Description:
DISPENSING APPARATUS

Background of the invention

[0001] The invention relates to a dispensing apparatus for dispensing receipts, slips or tickets from a continuous strip of material.

[0002] Specifically, but not exclusively, the invention can be used in a dispensing apparatus for dispensing receipts, slips or tickets located in a public place, for example a self-service fuel dispenser that automatically generates a payment receipt for the customer.

[0003] The invention can be advantageously applied in any situation in which it is necessary to separate, intermittently, receipts, slips or tickets from a relatively long continuous strip.

[0004] In particular, the present invention refers to a dispensing apparatus made in accordance with the preamble of the first claim.

[0005] Such a dispensing apparatus is already known, from example from patent publication US 2006/0210344.

[0006] One of the problems of known cutting apparatuses of this type is to coordinate the intermittent advancement of the strip, necessary for the issuing of the ticket, slip or receipt, with tensioning of the strip, which is necessary for the stationary blade to be able to cut the end portion of the strip that will form the ticket, slip or receipt.

[0007] In particular, there is the risk that the strip of paper is tensioned when the driven advancement means of the strip is still active. This could cause different drawbacks, such as, for example, an irregular cut of the ticket and/or an entanglement of the strip and/or incorrect printing of the ticket and/or failure to dispense the subsequent ticket.

Summary of the invention

[0008] One object of the invention is to provide a solution to the aforesaid problem of the prior art.

[0009] One advantage is to ensure regular advancement and/or printing and/or cutting of the strip.

[0010] One advantage is to make a dispensing apparatus that is usable in particular in a dispenser of tickets or receipts starting from a continuous strip of material, which is able to ensure regular and orderly movement of the strip.

[0011] One advantage is to prevent entanglement of the strip and/or incorrect printing of the ticket.

[0012] One advantage is to give rise to a constructionally simple and cheap dispensing apparatus.

[0013] Such objects and advantages and still others are achieved by the apparatus, by the use and by the method according to one or more of the claims set out below.

[0014] In one example, a dispensing apparatus comprises: driven supply means arranged for making a strip of material advance along a preset path; sensor means that is able to send a signal indicating a strip tensioning situation (for cutting a ticket or receipt); (electronic) control means that, in response to this signal, interrupts (immediately) any advancement of the strip by the supply means.

[0015] In one example, a method comprises the steps of: providing a stationary blade along a supply path of a continuous strip of material; separating a receipt or ticket from the strip by a cut with the stationary blade when the strip is tensioned, for example by a user who pulls an end thereof; interrupting driven supply means, which make the strip advance, if a sensor detects that the strip has been tensioned to be cut by the stationary blade.

Brief description of the drawings

[0016] The invention can be better understood and implemented with reference to the attached drawings that illustrate one embodiment by way of non-limiting example.

[0017] Figure 1 is a diagram in a vertical elevation of one embodiment of the apparatus in question.

[0018] Figure 2 shows the apparatus of figure 1 in a different operating configuration.

Detailed description

[0019] With reference to the above figures, with 1 overall a dispensing apparatus has been indicated comprising a housing 2 having an outlet 3 from which a user can receive a strip 4 of material, in particular paper material or material similar to paper. The housing 2 is intended, in particular, to contain the various elements of the apparatus that will be disclosed below. The housing 2 may have, for example, a substantially box shape. The outlet 3 may comprise, for example, a slit (arranged horizontally in length) that is suitable for the passage of the strip 4 and is obtained in an outlet mouth arranged on a front wall of a dispenser of tickets and/or receipts.

[0020] The dispensing apparatus 1 is used, in particular, for separating, intermittently, receipts, tickets, or similar objects (for example a receipt or ticket printed in real time, at the request of a user, just before cutting) from a continuous strip of relatively long material.

[0021] The dispensing apparatus 1 may be used in combination with a printing device as part of a distributor or dispenser of receipts and/or tickets printed from a continuous strip (made of paper or similar material).

[0022] The dispensing apparatus 1 may be used, for example, in a dispensing apparatus for dispensing receipts and/or tickets that is located in a public place. In the case in point the dispensing apparatus 1 is used in a self-service fuel dispenser that automatically generates a payment receipt for the customer.

[0023] In the specific example the dispensing apparatus 1 comprises a supply path 5 of the continuous strip. This path 5 will be at least partially arranged inside the housing 2. The strip may advance to the outlet 3 guided to follow the supply path 5. The continuous strip 4 will be, in particular, guided by guiding means comprising, for example, fixed (shaped) guiding walls that convey the strip. On the path 5 roller guiding means (of known type) may be possibly arranged. In particular, the continuous strip may be fed from a magazine R (for example a roll or a reel) that may be housed inside the housing 2.

[0024] The dispensing apparatus 1 comprises a stationary blade 6 arranged for cutting the strip 4 along the supply path 5. In particular, the stationary blade 6 will be arranged upstream (with reference to an advancement direction of the strip along the path 5) of the outlet 3. The stationary blade 6 may have a cutting edge (for example of serrated or other type) extending transversely (perpendicularly) to the advancement direction of the strip 4 (in particular, to the advancement direction that the strip will have at the blade 6). The supply path 5 of the strip may comprise, at the stationary blade 6, a curve with the inner side facing the blade 6. The stationary blade 6 may comprise a flat body, for example with a laminar shape, having the aforesaid cutting edge.

[0025] The dispensing apparatus 1 may further comprise supply means for supplying the strip intermittently along the supply path 5. In particular the supply means will be arranged for making the strip advance until at least one end thereof emerges from the outlet 3. This end can, in particular, be grasped by the user to pull and thus tension the strip to have the ticket or receipt separated by means of the stationary blade 6. Cutting the strip 4 to separate the receipt or the ticket may in fact be caused by the user, who tensions the strip by pulling the end thereof that exits the outlet.

[0026] The supply means may be arranged, as in this example, along the supply path 5 upstream of the blade 6, in such a manner that the supply means is not able to tension the strip downstream of the blade. In the case in point there are no strip advancement or dragging means arranged downstream of the blade 6, i.e. arranged between the blade 6 and the outlet 3 of the strip 4.

[0027] The supply means may comprise, as in the example disclosed here, a printing device (in particular a thermal printing device) having at least one strip advancement roller 7. In the case in point, the printing device further comprises a (thermal) printing head 8 cooperating with and opposite the advancement roller 7. The strip 4 will pass, with intermittent (controlled) motion, between the (thermal) printing head 8 and the advancement roller 7, to print the receipt or ticket (in real time).

[0028] The printing device will be controlled by a (programmable) central processing unit CPU that will guide the intermittent advancement of the strip 4, in particular during the printing step.

[0029] The dispensing apparatus 1 may comprise, as in this example, a paper-finished sensor 9, for example a sensor without contact (optical, electromagnetic or other type of sensor). In the case in point, the paper-finished sensor 9 comprises a photocell. The paper- finished sensor 9 may be arranged between the stationary blade 6 and the outlet 3.

[0030] The apparatus 1 comprises at least one movable element 10 arranged for being moved by the strip 4 when the strip is tensioned (for example by a user, as in this case, or by tensioning means, in particular of mechanical type, in other examples), for being cut. The movable element 10 is capable of taking on at least one first normal rest position and at least one second position that is moved with respect to the first position.

[0031] When the strip portion 4 arranged downstream of the blade 6 is not tensioned, the movable element 10 will be in the first normal rest position (figure 1). When the strip portion 4 arranged downstream of the blade 6 is tensioned to separate the ticket by cutting the blade 6, the taut strip 4 will push the movable element 10 towards the second position (figure 2).

[0032] The movable element 10 may be arranged upstream of the stationary blade 6 (with reference to the advancement of the strip 4). In the case in point the movable element 10 is arranged contiguously alongside the stationary blade 6. In other examples, which are not shown, the movable element could be arranged far from the stationary blade 6.

[0033] The movable element 10 may be suitable for performing a rectilinear movement, as in the illustrated example, parallel to a lying plane defined by at least one part of the stationary blade 6 (in particular a flat blade part, for example of laminar shape, that has the cutting edge). In other examples, which are not shown, the movable element may perform an oscillating movement, for example a rotation around a hinge or round a rotation pivot.

[0034] The apparatus 1 may comprise elastic means 11 (for example at least one spring) operating in contrast with the movement of the movable element 10 performed by the tensioned strip 4. The elastic means will bring the movable element 10 in the first normal rest position after the strip portion (ticket or receipt) has been separated by the blade 6, so that the strip 4 is no longer taut.

[0035] The movable element 10 may be supported by the aforesaid elastic means 11. The elastic means could comprise, in other examples that are not illustrated, an elastic hinge, an elastic lamina, an elastically deformable portion of the same movable element, etc.

[0036] The dispensing apparatus 1 comprises sensor means to detect the movement of the movable element 10 performed by the strip 4 tensioned to be cut. This sensor means may comprise, in particular, a proximity sensor or a sensor detecting the presence/absence of the movable element 10. This sensor means may comprise, as in the specific example, a contactless sensor 12 (optical sensor, electromagnetic sensor, etc) operationally associated with the movable element 10 or with the elastic means 11. In particular, the contactless sensor 12 may comprise a photocell operationally associated with the movable element 10.

[0037] In one example that is not illustrated, the movable element could comprise an electric switch or pushbutton that can be moved by the strip from a first normal rest position (for example an open switch or pushbutton position) to a second position (for example a closed switch or pushbutton position) in which it is pressed by the tensioned strip. In this case, the sensor means may comprise, for example, an electric contact that is opened or closed according to the position (first or second) of the switch or pushbutton and which can send a corresponding opening or closing signal.

[0038] The dispensing apparatus 1 comprises control means (in particular of electronic type) configured for controlling the supply means (in particular the printing device having the strip dragging roller 7) in response to signals received from the sensor means (sensor 12). Such control means comprises means for interrupting the advancement of the strip 4 by the aforesaid supply means when the sensor means (sensor 12) detects the movement of the movable element 10 performed by the strip 4 that has been tensioned to be cut. In the case in point the control means comprises the central processing unit CPU which will be provided with the aforesaid means for interrupting that stops the advancement means of the strip as soon as the strip is tensioned. [0039] The aforesaid central processing unit may be programmable and the aforesaid interrupting means may comprise programme instructions that can be implemented by the control unit. Such programme instructions will implement a method for dispensing receipts or tickets that comprises at least the following steps: activating the driven supply means to supply (intermittently, in particular if a ticket or receipt is requested by a user) the continuous strip 4 of material along the supply path 5; detecting (by receiving a signal from the sensor means) the movement of the movable element 10 that is moved by the strip when the strip is tensioned to be cut; interrupting the supply means if it is detected that, at the movement of the movable element 10, the supply means is still active, so as to stop immediately the supply of the strip 4 to prevent the driven advancement of the strip simultaneously with the cutting of the ticket or receipt.

[0040] In use, when the user pulls the strip end that protrudes outside the outlet 3 (after the printing device has printed a strip portion), the strip is tensioned (to separate a ticket or receipt by cutting the strip portion 4 by the blade 6) and consequently the movable element 10 is lowered by the strip, which pushes the movable element 10 contrasting with the elastic means connected to the movable element. If, during this step of separating the ticket or receipt from the strip 4, the strip is still dragged forwards by the supply means (roller 7), the central processing unit CPU will immediately stop this supply means (roller 7), so as to ensure that the strip, whilst it is tensioned (downstream of the stationary blade 6), it is not simultaneously dragged forwards by driven supply means (upstream of the stationary blade 6).

[0041] Owing to the fact that the apparatus in question envisages this situation (i.e. simultaneity of tensioning and driven advancement of the strip), the operation of the apparatus is safe, regular and reliable: in particular cutting is precise and complete, the formation of entanglements and jams is prevented, the issuing of the subsequent ticket is guaranteed, the printing of the ticket is correct.
