Description

Unmanned self checkout {Unmanned self checkout}

The present invention relates to an unmanned self-checkout counter, and more specifically, it can contribute to reducing labor costs by allowing people to calculate and pay for the items they purchase without a store clerk, and in particular, unlike before, envelopes are automatically issued. This is about an unmanned self-checkout counter that can increase convenience of use and significantly improve structure and space efficiency compared to the conventional method.

After purchasing goods at a department store or supermarket (goods store), etc., a POS (Point Of Sales) system is usually used to pay. Here, the POS system is a system that combines the functions of a cash register and a computer terminal, and is a computer that calculates by reading the code printed on the price tag with a reader. Typically, it refers to a terminal installed in front of the cash register and is handled by a clerk who is allowed access.

The method of calculating items using a POS system is traditional and is still used in most supermarkets, but recently, unmanned self-checkout machines are becoming more widespread, especially in large stores.

The unmanned self-checkout counter is a type of computer for calculations with the POS system mentioned above built in, and allows individual consumers to directly calculate and pay for purchased items without a clerk by touching the screen. These unmanned self-checkout machines are gradually spreading in line with the recent trend of unmanned operations.

Although these unmanned self-checkout machines have the advantage of reducing labor costs and being convenient to use, existing unmanned self-checkout machines generally only have the function of self-checking out purchased items, so bags for packaging items must be handled separately. There is a downside to this.

Usually, payment is made by placing an envelope next to the cash register, but in this case, separate personnel may be needed to dispense the envelope, which does not correspond to complete unmanned operation. In particular, considering that the existing method may be structurally or spatially inefficient in that it requires a separate structure or space to load or place envelopes next to the checkout counter, a new concept of unmanned self-service machine with an envelope dispensing function is proposed. The need for checkout counters is emerging.

Referring to these drawings, the unmanned self-checkout unit according to this embodiment can calculate the items purchased by the person and pay for them without a clerk, contributing to reducing labor costs. In particular, unlike the prior art, the unmanned self-checkout machine can contribute to reducing labor costs, and in particular, unlike the conventional bag, it is possible to use an envelope, that is, a unit envelope (60 ) can be paid automatically, which not only improves convenience in use, but also improves structure and space efficiency significantly compared to before.

The unmanned self-checkout unit according to this embodiment, which can provide this effect, includes a product calculator 1 with a built-in means for calculating purchased products, and a product calculator 1 provided on one side of the product calculator 1 to package the purchased products. Envelopes are built in and may include an automatic envelope dispensing machine 100 that automatically dispenses envelopes when the product calculation is completed.

Let’s briefly learn about the product calculator (1). The product calculator 1 is, for example, an unmanned calculation computer called a kiosk, and may include a calculator body 10 and a touch screen 20 provided on one side of the calculator body 10.

The calculator body 10 is equipped with a device, such as a barcode reader, to read information on purchased items. A fixed or handy barcode reader may be applied to the calculator body 10. Of course, methods other than the barcode reader can also be applied to the calculator body 10, and all of these matters should be considered to fall within the scope of the present invention.

The touch screen 20 is a part where purchased items are actually displayed on the screen. All matters related to product information, purchase (payment), such as price, quantity, discount, card payment, etc. can be easily implemented through touch.

For reference, the appearance, shape, and structure of the product calculator 1 shown in FIG. 1 are only one example. In other words, the article calculator 1 does not necessarily have to have the same structure as that shown in FIG. 1 . Accordingly, the present invention is not limited to the shapes in the drawings.

As described above, the automatic envelope dispensing machine 100 is provided on one side of the product counter 1 and has a built-in envelope for packaging the purchased product, and serves to automatically dispense the envelope when the product calculation is completed.

Since the automatic envelope dispensing machine 100 is applied to the unmanned self-checkout counter according to this embodiment, it is possible to implement completely unmanned automation by breaking away from the previous method of dispensing envelopes next to the checkout counter.

Meanwhile, the automatic envelope dispensing machine 100 applied to this embodiment can cut the roll type roll envelope 50 into at least one unit envelope 60 using the perforation line 70, as shown in FIG. 2. This is a roll-type envelope automatic dispensing machine (100) that is provided.

In this way, when the roll-type envelope automatic dispensing machine 100 is applied, convenience can be provided in that it can be used for a long period of time by installing the roll envelope 50. However, when applying this roll-type envelope automatic dispensing machine (100), if one unit envelope (60) is torn from the roll envelope (50) using the perforation line (70), the back side of the unit envelope (60) is opened during the process of opening the unit envelope (60). The bag may be pushed to one side, making it difficult to use. Therefore, this embodiment provides a roll-type envelope automatic dispensing machine 100 that prevents this phenomenon from occurring.

The roll-type envelope automatic dispenser 100 is provided on one side of the dispenser main body 110 and the dispenser main body 110, and includes a roll bag holder 120 on which the roll envelope 50 is rotatably mounted, and the dispenser main body ( 110) and connected to the roll bag 50, and may include an envelope supply unit 130 that supplies while rotating the roll bag 50 so that the unit envelope 60 can be cut from the roll bag 50. there is.

The dispenser main body 110 is a structure that forms the skeleton of the roll-type envelope automatic dispenser 100. The structure and composition of the roll envelope holder 120, envelope supply unit 130, etc. are provided at each location in the dispenser main body 110.

The roll bag holder 120 is provided on one side of the dispenser main body 110 and forms a place where the roll bag 50 is rotatably mounted. The roll bag holder 120 can be applied in a structure that allows the roll bag 50 to be easily replaced.

A remaining roll amount detection sensor (not shown) may be provided around the roll bag holder 120. If a roll remaining amount detection sensor is provided, the remaining roll amount can be easily detected and quick response is possible without having to frequently open the roll-type envelope automatic dispenser 100. Information about the remaining roll amount may be displayed on the touch screen 20.

Meanwhile, the envelope supply unit 130 is provided in the dispenser main body 110 and connected to the roll envelope 50, and rotates the roll envelope 50 so that the unit envelope 60 can be cut from the roll envelope 50. It plays a supply role.

This envelope supply unit 130 includes an envelope drive motor 131 that provides driving force to rotate and supply the roll envelope 50, and is disposed in the unit envelope 60 area, which is the tip area of the roll envelope 50, A driving roller 132 that rotatably supports the unit envelope 60 is connected to the bag driving motor 131 and the driving roller 132, and the power of the bag driving motor 131 is applied to the driving roller 132. The motion transmission unit 140, which transmits rotational motion, is disposed on the outside of the driving roller 132 across a space through which the unit envelope 60 passes, and rotates with the driving roller 132 to move the unit envelope 60. It may include a driven roller 133 that supplies.

In this embodiment, at least one of the driving roller 132 and the driven roller 133 may be used as a rubber roller made of rubber. Accordingly, the plastic unit bag 60 can be exposed to the outside for a desired length without slipping between them.

The external exposure length of the unit envelope 60 exposed to the outside through the driving roller 132 and the driven roller 133 by the operation of the envelope driving motor 131 can be appropriately controlled by the controller 190.

At least one tension roller 134 is provided around the driving roller 132 and the driven roller 133. The tension roller 134 is provided on the path where the roll bag 50 is unwound, and serves to provide tension to the roll bag 50 to prevent the unwound roll bag 50 from sagging.

Accordingly, the position of the tension roller 134 may vary depending on the remaining amount of the roll bag 50, and a roller movement guide 135 is provided to guide this. The roller movement guide 135 is an arc-shaped bar member whose one end is rotatably connected to the dispenser main body 110 and whose other end movably supports and guides the tension roller 134.

An arc-shaped slit 111 is formed on the side of the dispenser main body 110 to guide the movement trajectory of the roller movement guide 135 connected to the tension roller 134. Due to the structure of the roller movement guide 135 and the arc-shaped slit 111, the tension roller 134 is stably guided in a given trajectory, thereby maintaining tension on the roll bag 50 so that the unwinding roll bag 50 does not sag. can be provided.

At least one guide roller 136 is provided around the tension roller 134. The guide roller 136 is disposed on the path where the roll bag 50 is unwound, and guides the bag as it is unwound from the roll bag 50. Accordingly, the number of guide rollers 136 can be appropriately selected.

The motion transmission unit 140 applied to the bag supply unit 130 is connected to the bag drive motor 131 and the drive roller 132, and converts the power of the bag drive motor 131 into the rotational movement of the drive roller 132. It plays a role in conveying. Various types of motion transmission units 140 can be applied, and in this embodiment, the pulley and belt types are applied.

The motion transmission unit 140 applied to this embodiment includes a drive pulley 141 connected to the motor shaft of the envelope drive motor 131, a driven pulley 142 axially coupled to the drive roller 132, and a drive pulley. It may include a belt 143 that is connected to 141 and the driven pulley 142 and transmits the driving force of the envelope drive motor 131 to the driven pulley 142 through the drive pulley 141. Accordingly, when the envelope drive motor 131 operates, the drive roller 132 rotates due to the action of the drive pulley 141, the belt 143, and the driven pulley 142, thereby rotating the driven roller 133. Due to the rotation of the roller 132 and the driven roller 133, the unit envelope 60 may be exposed to a certain amount. Then, the user can tear off the unit envelope 60 using the perforation line 70 and use it.

The roll-type envelope automatic dispensing machine 100 is further provided with a roller rotation mounting unit 150. The roller rotation mounting unit 150 has a driven roller 133 rotatably mounted and includes an envelope upper support 151 that supports the upper upper region of the unit envelope 60. Since the upper area of the unit envelope 60 can be stably supported by the upper envelope support 151 of the roller rotation mounting unit 150 forming a wide surface, the phenomenon of the unit envelope 60 being pushed to one side can be eliminated.

The roller rotation mounting unit 150 is provided with a mounting unit raising and lowering driving unit 155. The mounting unit raising and lowering driving unit 155 is connected to the roller rotation mounting unit 150, and serves to drive the roller rotating mounting unit 150 up and down so that the driven roller 133 approaches or is spaced apart from the driving roller 132. The mounting unit raising and lowering drive unit 155 is for adjusting the gap between the driving roller 132 and the driven roller 133, and can be applied as a screw-type manual structure.

Meanwhile, as described above, when the bag supply unit 130 operates, the unit bag 60 at the front end of the roll bag 50 can be torn off and used. That is, when the envelope drive motor 131 operates, the drive roller 132 rotates due to the action of the drive pulley 141, the belt 143, and the driven pulley 142, thereby rotating the driven roller 133. Due to the rotation of (132) and driven roller 133, the unit envelope 60 may be exposed to a certain amount. Then, the user can tear off the unit envelope 60 using the perforation line 70 and use it.

However, at this time, in the process of tearing the unit envelope 60 while applying force, the rear envelope may be pushed to one side. In this case, the envelope becomes stuck between the driving roller 132 and the driven roller 133, so the equipment leads to malfunction. Therefore, a means to prevent this shape is needed, which is handled by the up/down press 160 and the press up/down drive unit 170.

The up/down press 160 corresponds to the upper envelope support 151 of the roller rotation mount 150 with the unit envelope 60 in between, and includes an envelope lower support 161 that supports the lower region of the unit envelope 60. It is a structure that is driven up/down with respect to the roller rotation mounting unit 150. The up/down press 160 is made of an L-shaped steel plate structure similar to the roller rotation mounting unit 150.

The press up/down drive unit 170 is provided in the dispenser main body 110 and one side is connected to the up/down press 160, and when the unit envelope 60 is opened using the perforation line 70, the upper end of the envelope is supported. The action of 151 and the bag lower end support 161 serves to drive the up/down press 160 up/down so as to support the roll bag 50 at the rear end.

In other words, when opening the unit envelope 60 through the perforation line 70, holding the envelope behind it can eliminate the phenomenon of the envelope being pushed to one side, so during this operation, the press up/down drive unit ( 170) drives the up/down press 160 up so that the upper envelope support 151 and the lower envelope support 161 hold the envelope at the back.

A press up/down guide 163 is connected to the up/down press 160. The press up/down guide 163 is connected to the up/down press 160 and serves to guide the up/down movement of the up/down press 160.

And, a press raising/lowering driving unit 165 is connected to the up/down press 160. The press lifting and lowering driving unit 165 drives the up/down press 160 to raise and lower so that the driving roller 132 approaches or is spaced apart from the driven roller 133, similar to the action of the mounting unit lifting and lowering driving unit 155 described above. It plays a role. The press raising and lowering driving unit 165 is also for adjusting the gap between the driving roller 132 and the driven roller 133, and can be applied as a screw-type manual structure.

In this embodiment, the press up/down drive unit 170 is driven by a cam type and drives the up/down press 160 up/down. ) is applied. Since the cam-type press up/down driving unit 170 is applied, the up/down operation of the up/down press 160 can become flexible and accurate.

This cam-type press up/down drive unit 170 includes a press drive motor 171 that generates a driving force to drive the up/down press 160 up/down, and an up/down press 160. ) is connected to a cam member 172 whose main surface is in contact with the envelope lower support 161, a press drive motor 171, and a cam member 172, and the driving force of the press drive motor 171 is provided through a gear method. It may include a gear box 180 that transmits the rotational movement of the cam member 172.

In addition, the gear box 180 includes a box bracket 181 and a drive gear 182 connected to the motor shaft of the press drive motor 171, and is disposed within the box bracket 181 and meshes with the drive gear 182. A first driven gear 183 is rotatably connected to the box bracket 181 and a gear shaft 186 to which the first driven gear 183 is connected to one side is disposed on the outside of the box bracket 181. A second driven gear 184 rotatably connected to the other side of the gear shaft 186, and a third driven gear 185 tooth-meshed with the second driven gear 184 and coaxially connected to the cam member 172. ) may include.

Accordingly, when the cam member 172 is arranged, for example, as shown in FIGS. 15 to 17 by the action of the gear box 180 by the operation of the press drive motor 171, the cam member 172 moves the up/down press 160. Since it is pressed in the P1 direction of 15, the up/down press 160 can operate up, and as a result, the envelope is pressed between the upper support 151 and the lower support 161 of the bag. can be fixed. Therefore, even if force is applied to tear the front unit envelope 60, the envelope is not pushed to one side.

Meanwhile, a controller 190 is further applied to the unmanned self-checkout counter according to this embodiment. The controller 190 controls the operations of the bag supply unit 130 and the press up/down drive unit 170 with an organic mechanism based on the action of tearing the unit bag 60 from the roll bag 50. That is, when the envelope payment (supply) signal is transmitted, the unit envelope 60 is exposed to the outside by the envelope supply unit 130, and then the up/down press 160 is activated by the press up/down drive unit 170. It is controlled so that the rear envelope can be fixed by moving up.

At this time, the operation of the press up/down driving unit 170 has a separate photo sensor capable of detecting the area of the perforation line 70, and the controller 190 operates the press up/down driving unit 170 based on its signal. You can also control the operation of .

The controller 190 performing this role may include a central processing unit (191, CPU), memory (192, MEMORY), and support circuit (193, SUPPORT CIRCUIT).

In this embodiment, the central processing unit 191 operates the bag supply unit 130 and the press up/down drive unit 170 based on the action of tearing the unit bag 60 from the roll bag 50 through an organic mechanism. It may be one of a variety of computer processors that can be applied industrially to control

Memory 192 (MEMORY) is connected to the central processing unit 191. Memory 192 is a computer-readable recording medium that can be installed locally or remotely, for example, in a readily available storage medium such as random access memory (RAM), ROM, floppy disk, hard disk, or any other digital storage form. It may be at least one memory.

The support circuit 193 (SUPPORT CIRCUIT) is combined with the central processing unit 191 to support typical operations of the processor. This support circuit 193 may include a cache, power supply, clock circuit, input/output circuit, subsystem, etc.

In this embodiment, the controller 190 controls the operations of the bag supply unit 130 and the press up/down drive unit 170 with an organic mechanism based on the action of tearing the unit bag 60 from the roll bag 50. However, this series of control processes, etc. may be stored in the memory 192. Typically, software routines may be stored in memory 192. Software routines may also be stored or executed by other central processing units (not shown).

Although the process according to the present invention has been described as being executed by software routines, it is also possible that at least some of the processes according to the present invention are performed by hardware. As such, the processes of the present invention may be implemented as software running on a computer system, as hardware such as an integrated circuit, or as a combination of software and hardware.
