TECHNICAL FIELD

The invention relates to a shaped pouch production machine developed to be used in the production of pouches used in sectors and areas that require special pouches such as jewellery, textile, bijouterie and toy shops.

BACKGROUND ART

As you can access in the link of https://www.youtube.com/watch?v=VDva- XAmZMo, which is in the state of the art, the article of the invention is approximately 18 meters long. It is quite heavy and therefore requires a lot of time and effort for its maintenance, repair and troubleshooting. As it occupies a lot of space, the cost of space also increases.

In the state of the art, it is required to use a large number of resistances in the machines used. Using a large number of resistors and high capacity motors means that the machine consumes a lot of energy, which naturally increases the electricity costs.

Another problem that is desired to be solved in the state of the art is that at least 2 people need to work in the existing machines, and on average, 3-4 people should work at the machine since the machine is long and consists of too many parts and areas.

Another problem to be solved in the state of the art is that the waste rate in the pouches is very high. In addition, since the existing machines work in the hot-cold- hot-cold logic and water is required for the cooling units, a lot of water is used to cool the machine.

In conclusion, the abovementioned shortcomings and the inadequacy of the current practice entail an improvement in the respective technical field. Thus, there is a need for an invention to overcome the described problems. DESCRIPTION OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

The preferred alternatives of the embodiments of shaped pouch producing machine innovation of the invention, which are mentioned in this detailed description, are only intended for providing a better understanding of the subject- matter, and should not be construed in any restrictive sense.

The invention relates to a shaped pouch production machine, as seen in Figure 1 and Figure 2, containing bobbin binding (1 ), second layer bobbin binding (2), edge control unit (3), cover tape apparatus (4), profile locking apparatus (5), tension control dancer (6), edge welding plunger (7), sonic welding (7.1), first elevator (8), shaped wide welding unit (9), second elevator (10), first servo puller (11), shaped cutting blade unit (12), second servo puller (13), separator pushing unit (14), product exit conveyor unit (15), third servo puller (16), cold guillotine blade (17) and exit conveyor (18).

Bobbin brakes of bobbin binding (1 ) and second layer bobbin binding (2) are extremely important in terms of keeping the material in a stable tension in the machine. This tension is controlled by the brakes in the bobbin binding (1). In preferred embodiment of the invention, bobbin binding (1) unit allows double binding of film bobbins of various raw materials with 1000 mm diameter and 700 mm width in single bobbin binding (1 ), 500 mm diameter and 700 mm width in second layer bobbin binding (2). These dimensions cannot be limited. Thanks to this double bobbin binding (1 ) feature, material of the upper and lower layers of the shaped cut packaging pouches to be produced can be selected freely. Bobbin binding (1) can be considered as the lower layer, and the second layer bobbin binding (2) as the upper layer, where one or more materials can be used. Examples: It allows the use of materials such as transparent laminated, graphic printed laminated, windowed laminated materials in the upper layer and laminated paper, cardboard, fabric, aluminum, metallized, etc. materials in the lower layer and manufacturing high-level tactile and visual products. The place where these two bobbins are present is where the materials are connected.

Edge control unit (3) is the unit that enables the single bobbin or double bobbin films moving on the machine to move in a straight line with the desired sensitivity. This unit continuously reads the defined edge of the bobbin with the photocell eye and moves the bobbin group to the required direction, preventing the film from slipping on the machine. It goes left and right with the car inside and keeps the goods in the center.

Cover tape apparatus (4) is an apparatus added according to the customer's demand for the pouches produced with the cover tape. Customers, who put their products in the packages manufactured, can use pouches that can be closed properly by using cover tape, getting rid of unaesthetic appearances for example due to duct tape. The cover tape apparatus (4) used in the invention provides this possibility. The roller presses on the cover tape apparatus (4) and the tape comes on the apparatus and the tape adheres and closes the mouth of the pouch.

Profile locking apparatus (5), reclosable profile locks are a feature that is growing at an extraordinary rate in the packaging industry and preferred by consumers. This lock system, which allows them to repeatedly open and close the pouches of the products they buy, can be applied perfectly thanks to the jaws on the machine. In this way, magnificent products will be produced by using this lock in shaped cut packaging pouches, creating an noncompetitive difference in the market. Instead of the profile locking apparatus (5), snap fasteners and Velcro fasteners can also be used. The pouch is inserted between the locking apparatus (5) and two lock jaws are joined and the lock is installed from both sides. Tension control dancer (6) provides a permanent flow of the material moving as start-stop fashion before the place where the dancer is used. During the operations on the machine, the goods have to stop in some areas and move nonstop in others. This tension, which is used to control the gap formed in start-stop and constant flow, also keeps the tension of the goods stable between the pulling rollers and the bobbin brake unwinding the goods. The tension control dancer (6) is the system that keeps the tension and compensation under control in the stations that require stop-start and continuous flow during the operations of the film, which is unwound from the bobbins in a controlled manner thanks to the brakes.

Sonic welding (7.1 ), which is a high frequency plastic welding technology, is a welding unit that ensures that extra thicknesses in the material caused by the locking system and similar applications are quickly crushed, and that a stronger fusion of the area where the lock applied to the produced packaging begins and ends is provided. Due to the size difference of the products to be produced, the sonic group can be precisely adjusted in order to weld to the desired place within the minimum and maximum length range allowed by the machine. The sonic welding (7.1 ) closes the pouch by sending a sound wave to the end of the lock. The edge welding piston (7), on the other hand, moves up and down and exerts the necessary physical pressure to weld the pouch.

The first elevator (8) and the second elevator (10) are intended to reduce the distance between two adjacent processing stations to multiples of the pitch distance of the product. The machine pulls the product, which is unwound from the bobbins in a controlled manner, in the desired product size at precise measurement values with servo motor rollers. This measurement of the pulled product does not correspond to the fixed center measurements between the stations. Elevators (8,10) and roller group equalize the goods pitch with the fixed measure between the two stations by lengthening or shortening the path that the goods will travel from the previous station to the next station. The shaped wide welding unit (9), which gives the machine its name, is the unit that heat-welds the outer edges of the desired width in the dimensions and forms determined according to the order. Welding jaws, which are prepared according to customer demand, provide the opportunity to easily connect to the unit from the center points with holes of fixed dimensions. The surface where the molds are attached is heated by the resistances placed in the aluminum body, and thus the mold easily reaches the temperature to weld.

The machine pulls the size of the desired product accurately at precise values, with the help of the servo-controlled rollers. There are 3 pulling roller groups in the machine. These are the first servo puller (11 ), the second servo puller (13) and the third servo puller (14). It is important to pull the product, on which processes such as welding and cutting, are made on these rollers, in a straight and wrinkle- free fashion from the first process to the last process. Puller rollers are driven by the bottom roller, and the top roller offers the advantage of easy transfer of goods as pressure rollers with pneumatic control. Servo pullers ensure that the pouches do not come wrinkled or stretched (11 ,13,16).

Shaped cutting blade unit (12) is the unit that comes after the unit that heat-welds the outer edges of the desired width in the determined dimensions and forms and produces the final product by cutting from the outer frame of this welding. Blade jaws, which are prepared according to customer demand, provide the opportunity to easily connect to the unit from the center points with holes of fixed dimensions. The mold of each blade is different, cutting is done with individual blades. It does not cut 100 % of the pouch, but ensures that it is cut to a large extent. After this step, the separator pushes the final product in the pushing unit (14) to separate the product from the material with a pneumatic cylinder and leaves it on the conveyor.

Product exit conveyor unit (15) is the place where the product to be seperated by pushing it with a pneumatic cylinder, is left on it. This unit enables the final product to be taken out of the machine, either by stacking on a piece-by-piece basis or by moving one pitch for each product, with the precision of a stepper motor. Cold cut guillotine blade (17): The machine can also be used for flat-cut goods with locks, bellows, snap fasteners, cover tapes, etc., in the non-shape cut works. For this, straight work can be cut easily by connecting the flat welding jaw to the shaped cutting units of the multifunctional machine. In straight cutting works, the products are cut with this cold cut guillotine blade (17) to obtain the final product.

The machine uses this exit conveyor (18), which is at the forefront in straight cutting works other than shaped cutting. Thus, both shaped cuts and straight cut products can be produced on the same machine. The final product comes out of this exit conveyor (18).
