BACKGROUND Field

[0001] Embodiments generally relate to systems and methods for producing pressware. More particularly, such embodiments relate to systems, forming die assemblies, and methods for producing paper plates.

Description of the Related Art

[0002] Machinery for making pressware typically has a pressware forming tool that utilizes die pairs. The die pairs generally have an upper male portion or punch as well as a lower female portion or die. The upper male portion is generally a movable die and the lower female portion is generally a stationary die that receives the upper male portion during production. Once the pressware is formed, the exiting formed pressware and the incoming unformed paperboard are typically on the same plane. Speed is limited due to the fact that the formed pressware must be sufficiently out of the lower female die to allow the unformed paperboard to enter the lower female die. The inherent slow rate of removing formed pressware and advancing incoming unformed paperboard on the same plane is inefficient with time and creates negative effects typically associated with pre-cut blank handling processes, such as complicated indexing of the pre-cut blanks advancing into the lower female die.

[0003] There is a need, therefore, for improved systems, forming die assemblies, and methods for producing pressware.

DETAILED DESCRIPTION

[0014] Figure 1 depicts a perspective view of a pressware system 50 for producing, forming, or otherwise making pressware products that can include a press assembly 100 and a paper feed system 60, according to one or more embodiments. Figures 2A-6B depict several perspective views of the press assembly 100. The press assembly 100 can be configured to produce pressware products and can include an upper moveable platen 140, a lower moveable platen 160, a stationary platen 120, a punch platen 130, and one or more forming die assemblies 150.

[0015] Each forming die assembly 150 can include an upper forming die 170 and a lower forming die 180. The upper forming die 170 can be coupled to the upper moveable platen 140 and the lower forming die 180 can be coupled to the lower moveable platen 160. The upper forming die 170 and the lower forming die 180 can be configured to adjoin or come together within a passageway 126 (shown in Figure 2 A), such as to contact and press a substrate for producing a pressware product.

[0016] Figures 1-6B depict the press assembly 100 having one forming die assembly 150 disposed between the upper moveable platen 140 and the lower moveable platen 160. However, the press assembly 100 can generally include a plurality of forming die assemblies 150, such as two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, or twenty forming die assemblies 150. In some configurations, the press assembly 100 can include two to about twenty forming die assemblies 150, two to about twelve forming die assemblies 150, two to about ten forming die assemblies 150, or two to about seven forming die assemblies 150 disposed between the upper moveable platen 140 and the lower moveable platen 160. In other examples, the press assembly 100 can include two to about six forming die assemblies 150. In other examples, the press assembly 100 can include two, three, four, or five forming die assemblies 150. Regardless of the number of forming die assemblies 150 in the press assembly 100, each forming die assembly 150 can include a set of the upper and lower forming dies 170, 180.

[0017] The stationary platen 120 can have an upper surface 122, a lower surface 124, and one or more passageways 126 extending through the stationary platen 120 between the upper surface 122 and the lower surface 124, as depicted in Figure 2 A. The stationary platen 120 can be directly or indirectly coupled to or otherwise attached to a support structure 102, such as a frame, a housing, a body, or other component of the press assembly 100, as depicted in Figure 1. In some examples, one or more ledges 108 can be coupled to one or more support structures 102 and the stationary platen 120 can be disposed on, coupled to, attached to, or otherwise supported by the ledges 108. The stationary platen 120 can be positioned or otherwise disposed in a horizontal or substantially horizontal position within the press assembly 100 such that the upper surface 122 can face the upper moveable platen 140 and the lower surface 124 can face the lower moveable platen 160, as depicted in Figures 1 and 2 A.

[0018] The stationary platen 120 can include the same number of passageways 126 as the number of forming die assemblies 150 included in the press assembly 100. Figures 1-6B depict the stationary platen 120 having one passageway 126 extending through the stationary platen 120. However, the stationary platen 120 can generally include a plurality of passageways 126, such as two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, or twenty passageways 126 extending therethrough and between the upper surface 122 and the lower surface 124. In some exemplary configurations, the stationary platen 120 can include two passageways 126 to about twenty passageways 126, two passageways 126 to about twelve passageways 126, or two passageways 126 to about seven passageways 126 extending through the stationary platen 120.

[0019] Figure 1 further depicts that the upper moveable platen 140 can be disposed above the stationary platen 120. The upper moveable platen 140 can be configured to move toward and away from the upper surface 122 of the stationary platen 120. The lower moveable platen 160 can be disposed below the stationary platen 120. The lower moveable platen 160 can be configured to move toward and away from the lower surface 124 of the stationary platen 120. In one configuration, the upper moveable platen 140 and the lower moveable platen 160 can be independently configured to move linearly. As used herein, the term "linearly" means any straight or substantially straight line or path. In another configuration, the upper moveable platen 140 and the lower moveable platen 160 can be independently configured to move non-linearly. As used herein, the term "non-linearly" means any non-straight line or path.

[0020] Referring again to Figure 1, the punch platen 130 can be disposed between the upper moveable platen 140 and the stationary platen 120. The punch platen 130 can have an upper surface 132, a lower surface 134, and one or more passageways 136 extending through the punch platen 130 between the upper surface 132 and the lower surface 134, as depicted in Figure 2A. The punch platen 130 can be positioned or otherwise disposed within the press assembly 100 such that the upper surface 132 can face the upper moveable platen 140 and the lower surface 134 can face the stationary platen 120, as depicted in Figures 1 and 2A. For example, the punch platen 130 is shown as horizontal or substantially horizontal (e.g., a horizontal position) relative to the movements of the upper moveable platen 140 and the lower moveable platen 160.

[0021] The punch platen 130 can include the same number of passageways 136 as the number of forming die assemblies 150 contained in the press assembly 100. Figures 1-6B depict the punch platen 130 having one passageway 136 extending through the punch platen 130. However, the punch platen 130 can generally include a plurality of passageways 136, such as two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, or twenty passageways 136 extending therethrough and between the upper surface 132 and the lower surface 134. In some exemplary configurations, the punch platen 130 can include two passageways 136 to about twenty passageways 136, two passageways 136 to about twelve passageways 136, or two passageways 136 to about seven passageways 136 extending through the punch platen 130.

[0022] The punch platen 130 can be configured to move (e.g., vertically move) toward and away from the stationary platen 120. In some embodiments, the punch platen 130 can be coupled to the upper moveable platen 140 or the stationary platen 120 by one or more punch springs 137, and/or one or more other extendable members. Extendable members can include, but not limited to, one or more mechanical, hydraulic, and/or pneumatic extendable members. Exemplary extendable members can be or include one or more springs, cams, rams, actuators, pistons, shafts, rods, arms, guides, rack and pinion systems, or any combination thereof. The one or more punch springs 137 can be configured to control at least a portion of the movement by the punch platen 130. The portion of the movement of the punch platen 130 can be independent of the upper moveable platen 140.

[0023] The press assembly 100 can also include a shearing die 131 that can include an upper shear 133 and a lower shear 135, as depicted in Figure 2B. The upper shear 133 can be coupled to the punch platen 130 and can be partially or completely disposed around the passageway 136, such as at or on the lower surface 134. The lower shear 135 can be coupled to the stationary platen 120 and can be partially or completely disposed around the passageway 126, such as at or on the upper surface 122. The upper shear 133 can be configured to move to at least partially extend into the passageway 126 and to cut a blank or substrate from an incoming web or paper 90. Subsequently, the blank or substrate can be further processed, such as pressed between the upper forming die 170 and the lower forming die 180, to produce the pressware product.

[0024] The press assembly 100 can include a plurality of the shearing dies 131, and can generally include the same number of shearing dies 131, as the number of forming die assemblies 150 contained in the press assembly 100. The press assembly 100 can include one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, or twenty of the shearing dies 131. In some configurations, the press assembly 100 can include two to about twenty of the shearing dies 131, two to about twelve of the shearing dies 131, two to about ten of the shearing dies 131, or two to about seven of the shearing dies 131. In some examples, the press assembly 100 can include two to about six of the shearing dies 131. In other examples, the press assembly 100 can include two, three, four, or five of the shearing dies 131.

[0025] Referring again to Figure 1, the paper feed system 60 can include one or more web or paper supplies or source 64 (e.g., rolls of web or paper), one or more decurling systems 66, one or more pull rolls 68, one or more paper feeds 72, 80, and one or more scoring units 78. Each of the decurling system 66, the pull roll 68, the paper feeds 72, 80, and the scoring unit 78 can be independently positioned or otherwise disposed in any position, including, but not limited to, horizontal positions, vertical positions, or any position therebetween. In one or more embodiments, the decurling system 66 can be disposed in a horizontal position and the scoring unit 78 can be disposed in a vertical position relative to the plane of the web or paper 90 passing therethrough, as depicted in Figure 1. In other embodiments, not shown, the decurling system 66 can be disposed in a vertical position, and independently, the scoring unit 78 can be disposed in a horizontal position relative to the plane of the web or paper 90 passing therethrough. Alternatively, in other embodiments not shown, the decurling system 66 and the scoring unit 78 can both be disposed in vertical positions or horizontal positions relative to the plane of the web or paper 90. In some embodiments, the scoring unit 78 can be disposed upstream of the paper feed 80, such that the web or paper 90 can be processed by the scoring unit 78 prior to passing through the paper feed 80, as depicted in Figure 1. In other embodiments, not shown, the scoring unit 78 can be disposed downstream of the paper feed 80, such that the web or paper 90 can be processed by the scoring unit 78 after passing through the paper feed 80.

[0026] The paper feed system 60 can be configured to treat, condition, and/or otherwise process fiber or paper containing materials and can feed or otherwise deliver a web of such fiber or paper containing material to the press assembly 100 for producing pressware products. In one embodiment, the paper feed system 60 can provide the web or paper 90 through the paper feed 80 and across the upper surface 122 of the stationary platen 120 along a web path or a web line 123, which can generally be in the plane of the incoming web or paper 90. The paper feed system 60 and the press assembly 100 can advance the web or paper 90 between the upper and lower forming dies 170, 180 of one or more forming die assemblies 150. The blanks or substrates 82 can be stamped, cut, or otherwise formed from the web or paper 90. The webbing scraps (not shown) can be formed from the remaining webbing or paper material from which the blanks or substrates 82 were cut. The webbing scraps (not shown) can be moved along the web line 123 and can be ejected out the opposite side of the press assembly 100 as the paper feed 80. A cutting tool 139, such as a blade, a scrap knife, or another type of blade or cutting instrument, can be disposed on the press assembly 100 and can be configured to sever or cut the webbing scrap 91 that exits from between the punch platen 130 and the stationary platen 120.

[0027] The formed substrates 82 can be processed to produce pressware products 92 which can be ejected or removed by different techniques from the press assembly 100. The pressware products 92 can be ejected or removed by movement of the lower knockout 184, by gaseous flow or burst from one or more nozzles 114, or a combination thereof. The pressware products 92 can be ejected or removed from the die assemblies 150 when the pressware products 92 are positioned below the web line 123. The pressware products 92 can be ejected or moved through one or more chute entrances 1 12 and to one or more chutes 1 10 via one or more nozzles 1 14. In one embodiment, the pressware products 92 can be ejected by a gaseous flow or one or more gas bursts directed by the nozzles 1 14 to move the pressware products 92 through the chute entrances 1 12 and to the chutes 1 10. Thereafter, the pressware products 92 can be moved from the chutes 1 10 to one or more conveying systems 1 16 to direct the pressware products 92 away from the chutes 1 10. Although Figure 1 depicts only one of the conveying systems 1 16 coupled to one of the chutes 1 10, one or more other conveying systems 1 16 can be operably coupled to the press assembly 100, such as to additional chutes 1 10.

[0028] The nozzles 1 14 can be disposed below the lower surface 124 of the stationary platen 120 and adjacent to each chute entrance 1 12 and/or each chute 1 10. The nozzles 1 14 can be configured to blow pressed products from the lower knockout 184 to the chute 1 10 via the chute entrance 1 12. The chutes 1 10 can be disposed at least partially below the lower surface 124 of the stationary platen 120 and the chute entrances 1 12 and can be attached to or formed within the lower surface 124 of the stationary platen 120. The chutes 1 10 and the chute entrances 1 12 can be configured to receive pressed products produced in the forming die assembly 150. In some examples, the press assembly 100 can also include two or more sets of the nozzles 1 14 and the chutes 1 10.

[0029] In one or more embodiments, the press assembly 100 for producing pressware can include a first driving member or the upper driving member 142 and a second driving member or the lower driving member 162, as depicted in Figure 1. The upper moveable platen 140 can be disposed above the stationary platen 120 and coupled to the upper driving member 142 and the lower moveable platen 160 can be disposed below the stationary platen 120 and coupled to the lower driving member 162. The upper driving member 142 can be configured to move (e.g., vertically move) the upper moveable platen 140 toward and away from the upper surface 122 of the stationary platen 120. Similarly, the lower driving member 162 can be configured to move (e.g., vertically move) the lower moveable platen 160 toward and away from the lower surface 124 of the stationary platen 120. The upper driving member 142 and the lower driving member 162 can be configured to provide movement (e.g., reciprocating movement) for the upper moveable platen 140 and the lower moveable platen 160, respectively, toward and away from the stationary platen 120. Each of the upper driving member 142 and the lower driving member 162 can be independently or include one or more rams, cams, actuators, shafts, arms, pistons, motors, or the like that can be configured to provide the movement toward and away from the stationary platen 120. In some examples, the upper driving member 142 and the lower driving member 162 can be independently or include one or more pneumatic or hydraulic rams, cams, actuators, or pistons. In other examples, the upper driving member 142 and the lower driving member 162 can be independently or include one or more shafts and/or motors, such as a concentric shaft coupled to a motor.

[0030] A system controller 70 can be operatively coupled to the press assembly 100 and the paper feed system 60 of the pressware system 50. The system controller 70 can include one or more microprocessors, one or more controllers, one or more switches, one or more software programs, and/or other equipment or devices that can activate and control one or more of components or systems of the pressware system 50, including, but not limited to, the paper feed system 60 and/or the press assembly 100. In one embodiment, as depicted in Figure 1, the system controller 70 can be a portion of or attached to the press assembly 100. In another embodiment, not shown, the system controller 70 can be independent or free standing from the press assembly 100. The system controller 70 can be independently operatively coupled to any components of the paper feed system 60 for advancing and processing the web or paper 90. For example, the system controller 70 can activate and subsequently operate or otherwise control the web or paper supplies or source 64, the decurling systems 66, the pull rolls 68, the paper feeds 72, 80, the scoring units 78, or any other component of the paper feed system 60. The system controller 70 can also independently be operatively coupled to any components of the press assembly 100 for further processing the incoming web or paper 90 and producing the pressware products 92. For example, the system controller 70 can activate and subsequently operate or otherwise control the upper driving member 142, the lower driving member 162, the lower knockout 184, the nozzles 114, the conveying systems 116, or any other component of the press assembly 100.

[0031] Figures 2 A and 2B depict perspective views of the press assembly 100. The upper forming die 170 can include a pressure ring 172, a forming punch 174, and an upper knockout 176. The pressure ring 172 can partially or completely encompass or encircle the forming punch 174 and the upper knockout 176. The pressure ring 172, the forming punch 174, and the upper knockout 176 can be configured to move with the upper moveable platen 140 toward and away from the lower forming die 180. Also, the pressure ring 172 and the upper knockout 176, independent of each other, can be configured to move separately of the forming punch 174 and/or the upper moveable platen 140. For example, the pressure ring 172 can be coupled to the upper moveable platen 140 by one or more pressure ring springs 173 and the upper knockout 176 can be coupled to the forming punch 174 by one or more upper knockout springs 177. Alternatively, not shown, the pressure ring 172 can be coupled to the upper moveable platen 140 by one or more extendable members (e.g., springs, pistons, actuators, cams, or rams) and the upper knockout 176 can be coupled to the forming punch 174 by one or more upper knockout springs 177 (e.g., springs, pistons, actuator, cams, or rams).

[0032] The lower forming die 180 can include a contour rim 182 and a lower knockout 184. The contour rim 182 can partially or completely encompass or encircle the lower knockout 184. The contour rim 182 and the lower knockout 184 can be configured to move with the lower moveable platen 160 toward and away from the upper forming die 170, and the lower knockout 184 can be configured to move separately of the contour rim 182. In some examples, the lower knockout 184 can be configured to be driven by a piston 186, such as a hydraulic or pneumatic piston, ram, cam, actuator, or shaft. In another embodiment, the press assembly 100 can include one or more lower forming springs 188 disposed within the lower forming die 180 or can be disposed between and coupled to the lower moveable platen 160 and the lower forming die 180. The lower forming springs 188 can be configured to produce a forming pressure across the forming die assembly 150. In some embodiments, the forming die assembly 150 can include one or more temperature control devices 152 within or coupled to the upper forming die 170 and/or the lower forming die 180. The temperature control devices 152 can be independently configured to maintain, regulate, and/or adjust (e.g., increase or decrease) the temperature of the upper forming die 170, the lower forming die 180, and/or portions or segments thereof. The system controller 70 can be operatively coupled to the temperature control devices 152 for independently controlling the temperatures of the upper forming die 170 and the lower forming die 180.

[0033] The press assembly 100 can also include a stripper plate 138 disposed from or below the lower surface 134 of the punch platen 130, depicted in Figures 2A and 2B. The stripper plate 138 can be coupled to the punch platen 139 by one or more stripper plate springs 128 disposed therebetween. The stripper plate 138 can be configured to move (e.g., vertically move) toward and away the upper surface 122 of the stationary platen 120 via the stripper plate springs 128. In one configuration, the stripper plate springs 128 can be disposed between and coupled to the punch platen 130 and the stripper plate 138. As shown in Figures 2 A and 2B, the stripper plate 138 is disposed below the lower surface 134 of the punch platen 130 with the stripper plate springs 128 in a decompressed state. In use, the stripper plate 138 can contact and tighten the incoming web or paper 90, such as to prepare the incoming web or paper 90 to be cut into substrates by the shearing die 131. As the stripper plate 138 contacts the incoming web or paper 90, compression in the stripper plate springs 128 can increase until the stripper plate springs 128 become fully compressed.

[0034] Any of the springs described herein, including, but not limited to, the stripper plate springs 128, the punch springs 137, the pressure ring springs 173, the upper knockout springs 177, and the lower forming springs 188, can be at a fully compressed state at different periods of the process cycle in the press assembly 100 or another press assembly. As used herein, in reference to any of the springs described herein, the term "fully compressed" means that the spring is compressed to a maximum compressibility of the spring relative to being used within a press assembly, but the spring itself can still have remaining compressibility. Similarly, as used herein, in reference to any of the springs described herein, the term "decompressed" means that the spring is decompressed to a maximum decompressibility of the spring relative to being used within a press assembly, but the spring itself can still have remaining decompressibility.

[0035] Figures 2A-6B depict exemplary views of the press assembly 100 at different opened or closed positions, according to one or more embodiments. The opened or closed positions of the press assembly 100 can be correlated to different stages of a process cycle.
