The case 40 is, for example, a rectangular parallelepiped box-shaped container, and includes an upper wall 41, a bottom wall 42, and four side walls 43, 44, 45, and 46 on the front, rear, left, and right sides. Tray openings 43a and 46a are formed in the front and rear side walls 43 and 46 of the case 40, respectively, into which the guide tray 31 of the holding tray 30 is disposed. The tray openings 43a and 46a are rectangular openings that are long in the first direction, and penetrate the side walls 43 and 46 of the case 40 in the inner and outer directions.

The pair of tray openings 43a and 46a are configured to have similar shapes, and for example, the width along the first direction is larger than the width direction dimension of the bag 100, and the vertical width along the third direction is larger than the stacking direction dimension of the bag bundle 100A. It also consists of a large number of people. For example, the front tray opening 43a is located slightly lower than the rear tray opening 46a, and a tray passageway is formed from the front tray opening 43a through the inside of the case 40 to the rear tray opening 46a. A holding tray 30 is disposed at. That is, the case 40 covers a part of the holding tray 30 and exposes at least a part of the area on the guide tray 31 where the bag 100 is arranged from the tray openings 43a and 46a.

The case 40 is provided with a thickness detection section 47. In this embodiment, the thickness detection section 47 includes a first displacement sensor 47a and a second displacement sensor 47b. The first displacement sensor 47a and the second displacement sensor 47b are respectively provided at two predetermined locations on the lower surface side of the upper wall 41 of the case 40 and facing above the plate portion 31a.

The first displacement sensor 47a is provided on the facing plate portion 31a at a position facing the detection portion C1 near the cutting portion 113b in the upper folded portion of the main body portion 111 of the bag 100. The first displacement sensor 47a detects the position of the detection region C1 on the outer surface of the folded bag bundle 100A at a predetermined timing or periodically, and transmits the detected position to the control unit 70.

The second displacement sensor 47b is located on the facing plate portion 31a at a position facing the detection portion C2 located on the bottom side of the folded portion 111a of the main body portion 111 of the bag 100 and at the lower folded portion. It is provided. The second displacement sensor 47b detects the position of the detection site C2 on the innermost side of the folded bag bundle 100A at a predetermined timing or periodically, and transmits the detected position to the control unit 70. Here, the second detection portion C2 is a detection position where the handle 112 and the holding piece 113 of the upper folded portion do not overlap.

A notification device 48 as a notification section is provided on the side wall 43 of the case 40. The notification device 48 includes, for example, a lighting device 48a such as an LED whose color and intensity of light can be changed. The notification device 48 is connected to the control unit 70, and under the control of the control unit 70 performs a lighting operation as notification processing.

The control unit 70 includes, for example, a processor, and manages the remaining amount of the bag based on information sent from the thickness detection unit 47. For example, the control unit 70 controls the operation of the notification device 48 based on information regarding the thickness detected by the thickness detection unit 47.

The control unit 70 performs a notification process to inform the user of the remaining amount of the bag 100, as an example of managing the remaining amount of the bag. For example, when the thickness of the bag bundle 100A falls below a certain value, the control unit 70 operates the lighting device 48a as a notification process, for example, lights up the lighting device 48a, assuming that the remaining amount of bags 100 falls below a certain number. Alternatively, for example, by changing lighting conditions such as color or blinking state, the user is informed that there are few bags left.

Note that the control unit 70 may be provided as a part of the notification device 48 or may be provided at another location of the bag holding device 10. Alternatively, the control unit 70 may be provided, for example, in a higher-level computer device connected to the bag holding device 10.

In the bag holding device 10 configured as described above, the holding tray 30 is inserted forward from the tray opening 46a at the rear of the case 40 along the tray path extending in the fourth direction downward from the front. It is positioned in contact with the rear surface of the front and rear side walls of the case 40 and set in the case 40. On the other hand, when the rear end portion of the holding tray 30 is pulled rearward from the rear tray opening 46a, the holding tray 30 is removed from the case 40.

When the holding tray 30 is removed from the case 40, the opening/closing plate 32a is rotated upward to open the plate portion 31a. In this open state, the main body part 111 of the bag bundle 100A is placed on the plate part 31a, the opening/closing plate 32a is closed, and the bent part 111a of the main body part 111 of the bag 100 is wrapped around the support rod 33 so that the handle 112 is in the front direction. Fold it so that it is placed in the Furthermore, the bag bundle 100A is placed on the holding tray 30 by placing the handle 112 on the opening/closing plate 32a. Furthermore, the bag bundle 100A is held on the holding tray 30 by hooking the hole 113a of the holding piece 113 onto the hook 35. At this time, the bottom of the bag 100 is led out from the front tray opening 43a, and the bent portion 111a of the bag 100 is exposed to the outside from the rear tray opening 46a.

In such a bag holding device 10, when a user pulls out the bags 100 from the tray openings 43a, 46a and uses them, the thickness of the bag bundle 100A in the main body 111 is reduced. For example, from the front tray opening 43a, the bags 100 on the inside of the fold are pulled out in order, and from the rear tray opening 46a, the bags 100 on the outside of the fold are pulled out in order. The control unit 70 controls the thickness detection unit 47 at a predetermined timing to perform a thickness detection process of detecting thickness information from the positions in the detection regions C1 and C2. Further, the control unit 70 detects the remaining amount and number of bags 100 from the data of the bag bundle 100A received from the thickness detection unit 47, and manages the remaining amount of bags. For example, when the thickness of the bag bundle 100A falls below a certain value, the control unit 70 determines that the remaining amount of bags 100 falls below a certain number and operates the lighting device 48a, for example, turns on the lighting device 48a, or the lighting device Notification processing is performed to change lighting conditions such as the color and blinking state of 48a to notify the user that the number of bags 100 remaining is small.

According to the bag holding device 10 according to this embodiment, it is possible to provide a bag holding device that can manage bags. That is, the bag holding device 10 manages and reports the number of bags 100 based on the thickness of the bag bundle 100A, and can realize the number management with a simple configuration in which a displacement sensor is disposed. Furthermore, in the bag holding device 10, the plurality of displacement sensors 47a and 47b are used to determine the positions of the first detection part C1 on the outer surface of the bag bundle 100A and the second detection part C2 on the inner surface of the bag bundle 100A that is folded in half. By arranging it at the detection position, the thickness information can be detected with high accuracy regardless of whether the bag 100 is pulled out from the front or rear. In addition, in the bag holding device 10, since the bag 100 that has been bent over the support rod 33 is held by the holding tray 30 that is tilted forward and downward, an appropriate tension is maintained by the weight of the bag 100, and the posture of the bag is stabilized. do. Furthermore, by restraining the bag bundle 100A with the sub-tray 32, the relationship between the thickness of the bag bundle 100A and the number of bags 100 is stabilized. Therefore, the thickness information of the bag bundle 100A can be detected with high precision using the displacement sensor.

Further, in the bag holding device 10, the thickness detection unit 47 can detect the thickness by setting the first detection portion C1 at a position where the bags 100 are unlikely to be scattered near the holding pieces 113 where the bags 100 are bundled by crimping. Information can be detected with high precision.

It should be noted that the present invention is not limited to the above-described embodiments as they are, but can be implemented by modifying the constituent elements within the scope of the invention at the implementation stage.

For example, in the first embodiment, an example is shown in which the displacement sensors 47a and 47b as the thickness detection section 47 are provided on the case 40 side, but the present invention is not limited to this. For example, in addition to the case 40, it may be provided at other locations such as the outer periphery of the plate portion 31a, the subtray 32, and the support rod 33.

Further, in the bag holding device 10 according to the first embodiment, an example is shown in which the detection parts C1 and C2 are arranged on the upper surface of the upper part and the upper face of the lower part of the folding, respectively, but the present invention is not limited to this. The position where the thickness is detected can be changed as appropriate, and may be only one of them.

For example, in the displacement sensor 47a, since the detection position C1 is arranged near the holding pieces 113 bundled by crimping or the like, it is possible to detect with high precision even with one displacement sensor 47a. Further, although a displacement sensor is used as the thickness detection section 47, the present invention is not limited to this.

For example, as another embodiment, a bag holding device 10A shown in FIG. The structure is such that the thickness at the bent portion 111a is detected. In the bag holding device 10A, the second damper section is provided on the outer periphery of the support rod 33 and is configured to press down the bag 100 from the outer periphery at a position close to the displacement sensor 47A. In this case as well, the thickness of the bag bundle 100A can be detected as in the first embodiment. Furthermore, since the bag bundle 100A is hung on the support rod 33 and held stably with an appropriate tension, if the position of the outermost bag 100 of the bag bundle 100A hung on the outer periphery of the support rod 33 is detected, The thickness of the bag bundle 100A can be detected with high precision. Therefore, even when the inner bag 100 of the bent part 111a is pulled out, and even when the outer bag 100 is pulled out, the position of the outer circumferential surface around the support rod 33 of the bent part 111a can be accurately determined. Thickness dimension can be detected. Furthermore, in the bag holding device 10A, a second damper section provided on the outer periphery of the support rod 33 at a position close to the displacement sensor 47A allows the support rod 33 to be moved from the outer periphery side in the same direction as the detection direction of the displacement sensor 47A. By pressing the bag bundle 100A toward the bag, it is possible to suppress the disorder of the bags 100 and reduce variations in thickness detection.

For example, in another embodiment of the bag holding device 10B shown in FIG. The structure is such that the thickness of the main body portion 111 located in the portion, that is, the dimension in the stacking direction, is detected. For example, it includes a transmission sensor 47B, a light emitting section 47c and a light receiving section 47d provided on the lower surface side of the opening/closing plate 32a of the subtray 32 and the upper surface side of the plate portion 31a facing the opening/closing plate 32a, respectively. That is, the light emitting section 47c and the light receiving section 47d are provided on one side and the other side in the stacking direction of the bag bundle 100A, respectively. In this case as well, the thickness of the bag bundle 100A can be detected as in the first embodiment. Furthermore, since the transmission sensor 47B is disposed between the opening/closing plate 32a and the plate portion 31a, it is less susceptible to the influence of external light and can therefore detect with high precision.

Further, a configuration may be adopted in which a plurality of thickness detection sections are provided at a plurality of different locations.

Further, the displacement sensors 47a, 47b, 47A, and the transmission sensor 47B as the plurality of thickness detection units may detect information on the presence or absence of the bag 100 as the thickness information.

For example, in the above embodiment, as an example of the notification processing, an example was shown in which the illumination device 48a is turned on to notify using light, but the invention is not limited to this. The notification process may be performed using a display or sound.

In the bag holding device 10 according to the first embodiment, an example has been shown in which the control unit 70 is provided in the bag holding device 10, but the control unit 70 is not limited to this, and is configured as a separate device and has a data processing function. It may be provided in a higher-level computer device having a. For example, a bag holding device 10C shown in FIG. 6 as another embodiment is connected to a checkout device 12 that is a host computer device. The configuration of the bag holding device 10C is similar to the bag holding device 10 according to the first embodiment except that it is connected to the checkout device 12.

As shown in FIG. 6, the checkout device 12 is a self-checkout POS (Point of Sales) terminal that is operated by a customer to perform checkout operations. The checkout device 12 includes a housing, an operation display section 52 as a notification section, a reading section 53, a receipt processing section 54, a money processing section 55, and a control unit that is connected to each section and controls the operation of each section.

A plurality of pieces of information, such as amount), touch panel input key display, etc., are switched and displayed depending on the processing stage.

Under the control of the control section 70, the monitor displays information regarding the thickness of the bag bundle 100A detected by the thickness detection section 47. The touch panel is provided on the surface of the monitor, and outputs information based on the position touched by the user to the control unit 70.

The reading unit 53 includes a barcode scanner and a card reader/writer.

The receipt processing section 54 includes, for example, a receipt storage section that stores a receipt paper wound into a roll, a receipt printer that prints on the receipt, and a receipt transport section that transports the receipt paper.

The control unit 70 includes, for example, a processor 71 such as a CPU, a main memory 72, an auxiliary storage device 73, a communication interface 74, and a system transmission line 75.

The control section 70 is connected to the operation display section 52, the reading section 53, the receipt processing section 54, and the money processing section 55, and controls the operation of each section. The control unit 70 drives the drive circuits of each unit, such as the monitor and the money processing unit 55, according to various programs based on data detected or input by various sensors, barcode scanners, card readers/writers, and touch panels. This controls the operation of each part.

For example, the control unit 70 drives the money processing unit 55 at a predetermined timing based on data detected by various sensors, a barcode scanner, a card reader/writer, a touch panel, or input, and performs money deposit/withdrawal processing. Performs various processing such as accounting, judgment, deposit, change calculation, change supply, etc.

Based on the thickness information of the bag 100 from the thickness detection unit 47, the control unit 70 performs a notification process to notify the user of the remaining amount of the bag as an example of remaining amount management. For example, the control unit 70 acquires the thickness information of the bag 100 from the 10C thickness detection unit 47 of the bag holding device via the communication interface 74, and when the thickness of the bag bundle 100A falls below a certain value, the Notification processing is performed assuming that the remaining number is below a certain value. For example, in addition to activating the notification device 48, or in place of the notification process by the notification device 48, notification information such as a message or an image indicating that there are few bags remaining is displayed on the operation display section 52.

According to any of the bag holding devices 10, 10A, and 10B described above, it is possible to provide a bag holding device that can manage bags.
