Description

An embodiment of the present invention relates to a bag storage device.

Self-checkout devices and accounting devices are known as devices that allow customers to process their own payments. For example, a self-checkout device is a device that allows customers to read product information and process their own payments. Also, for example, an accounting device is a device that allows customers to only process their own payments.

After using such a device to process the purchases, the customer places the items in a bag and takes them home. Such bags are called shopping bags, and are typically handed to customers by a store clerk in charge of customer service. Recently, it has also become common for customers to take the bags themselves, and for the bags to be hung around the device.

Also, for hygiene reasons, there are known techniques for storing multiple stacked bags on a pull-out shelf such as a soccer table, and techniques for folding multiple stacked bags and storing them in a bag storage device such as a holder or case. When the bags stored in the bag storage device run out, the store staff replenishes them with bags.

In each figure, the configuration is enlarged, reduced, or omitted as appropriate for the purpose of explanation. In addition, in the position of the bag storage device 1 shown in Figure 1, the surface on which the removal opening 231 of the housing 11 of the bag storage device 1 is provided is defined as the front, and the following explanation will be given with the front-rear direction, left-right direction, and up-down direction defined.

As shown in Figs. 1 to 5, the bag storage device 1 includes a housing 11, a tray 12, a holding member 13, and a speed change mechanism 14. The bag storage device 1 stores a plurality of bags 1000 removably in the housing 11, with the plurality of bags 1000 stacked to form a bag bundle 1001 being held by the holding member 13 in the tray 12. The bag storage device 1 is formed, for example, to be stackable.

In this embodiment, the bag 1000 is a so-called plastic shopping bag. As shown in Figs. 7 and 12, the bag 1000 comprises a main body portion 1011, a pair of handles (arms) 1012, and a hanging portion 1013. The main body portion 1011 is bag-shaped with one end closed and the other end open. The closed end of the main body portion 1011 forms the bottom of the bag 1000. In the following description, the extension direction of one edge that forms the bottom of the bag 1000 is referred to as the width direction of the bag 1000.

The pair of handles 1012 are integrally formed at the end of the opening side of the main body portion 1011. The hanging portion 1013 is one of the opening ends of the main body portion 1011 and is provided between the pair of handles 1012. The hanging portion 1013 has, for example, a hole 1014.

The hanging portion 1013 is integrally provided on the main body portion 1011 so as to be detachable from the main body portion 1011. As a specific example, a perforation or the like is formed at the boundary between the main body portion 1011 and the hanging portion 1013 for detaching the hanging portion 1013 from the main body portion 1011.

For example, as shown in Figures 7 and 12, multiple such bags 1000 are stacked to form a bag bundle 1001, folded in half at the main body portion 1011, and held by the holding member 13.

The housing 11 is a case that houses the tray 12. As shown in Figs. 1 to 4, the housing 11 has a pair of first walls 21, a pair of second walls 22, and a third wall 23. As shown in Figs. 1 and 4, the housing 11 also has an outlet 231 for removing the bag 1000. The housing 11 is formed, for example, into a rectangular box shape with an open back by the pair of first walls 21, the pair of second walls 22, and the third wall 23.

The pair of first walls 21 face each other at a distance that allows the tray 12 to be accommodated. The pair of first walls 21 face each other in the vertical direction. The upper first wall 21 is the top wall of the bag storage device 1. The lower first wall 21 is the bottom wall of the bag storage device 1.

As shown in FIG. 8, the lower first wall portion 21 has, on its main surface that forms the inner bottom surface of the bag storage device 1, a first engagement portion 211 that engages with a first stopper 312 (described later) of the tray 12, and a second engagement portion 212 that engages with a second stopper 313. Note that in FIG. 8, the lower first wall portion 21, the first engagement portion 211, and the second engagement portion 212 are indicated by two-dot chain lines.

The first engagement portion 211 is provided, for example, on the main surface of the lower first wall portion 21 at a position that engages with the first stopper 312 when the tray 12 is fully inserted into the housing 11. In this embodiment, the first engagement portion 211 is provided on the front side of the main surface of the lower first wall portion 21. The first engagement portion 211 engages with the first stopper 312 to restrict movement of the tray 12 in the direction of removal from the housing 11.

The second engagement portion 212 is provided, for example, in pairs. The second engagement portion 212 is provided, for example, at a position on the main surface of the lower first wall portion 21 where the tray 12 is pulled out from the housing 11 and the bags 1000 are replenished, where the second engagement portion 212 engages with the second stopper 313. In this embodiment, the second engagement portion 212 is provided on the rear side of the main surface of the lower first wall portion 21. By engaging with the second stopper 313, the second engagement portion 212 restricts the tray 12 from moving rearward beyond the position where the bags 1000 are replenished.

The pair of second walls 22 are continuous with the pair of first walls 21. The pair of second walls 22 face each other at a distance that allows the tray 12 to be accommodated. The pair of second walls 22 face each other in the left-right direction and form the left and right side walls of the bag storage device 1.

The third wall portion 23 has an outlet 231 in a part thereof. The third wall portion 23 is continuous with the pair of first wall portions 21 and the pair of second wall portions 22. The third wall portion 23 has, for example, a first inclined portion 232, a second inclined portion 233, an upper wall portion 234, a lower wall portion 235, and a pair of side wall portions 236. The first inclined portion 232 is inclined, for example, with respect to the opposing direction of the pair of first wall portions 21. The second inclined portion 233 is inclined, for example, with respect to the opposing direction of the pair of first wall portions 21 and is inclined in a different inclination direction from the inclination direction of the first inclined portion 232. The upper wall portion 234 is continuous with the upper first wall portion 21 and the first inclined portion 232. The lower wall portion 235 is continuous with the lower first wall portion 21 and the second inclined portion 233. The upper wall portion 234 and the lower wall portion 235 extend in the same direction as the first wall portion 21. The pair of side walls 236 are continuous with the first inclined portion 232, the second inclined portion 233, the upper wall portion 234, and the lower wall portion 235. The pair of side walls 236 extend in the same direction as the pair of second walls 22.

The outlet 231 is formed, for example, in a generally rectangular shape that is long in the left-right direction, i.e., in the opposing direction of the pair of second wall portions 22. The outlet 231 also includes a pair of openings 2311 that extend partially in the up-down direction from the center in the left-right direction, and a pair of openings 2312 that extend partially in the left-right direction from the center in the up-down direction.

As a specific example, the removal opening 231 is provided in the first inclined portion 232. The removal opening 231 faces the folded portion 1050 of the bag bundle 1001 stored in the housing 11. The pair of openings 2311 are arranged, for example, in the second inclined portion 233 and the upper wall portion 234. The pair of openings 2312 are arranged, for example, in the first inclined portion 232.

The outlet 231, which has a pair of openings 2311 and a pair of openings 2312, is long in the left-right direction, and its width in the up-down direction is set to be smallest at both ends in the left-right direction and largest in the center.

The removal opening 231 is set appropriately depending on the width of the bag 1000, the number of bags to be stored, etc., and may be shaped without a pair of openings 2311 and/or a pair of openings 2312, for example.

For example, such a housing 11 is formed by integrally molding a pair of first walls 21 and a pair of second walls 22 into a rectangular tubular shape, and covering one of the openings formed by the pair of first walls 21 and the pair of second walls 22 with a panel forming a third wall 23. The third wall 23 side of the housing 11 constitutes the front side, and the opening on the opposite side to the third wall 23 constitutes the back side.

The housing 11 may be constructed by assembling panels that respectively form the pair of first walls 21, the pair of second walls 22, and the third wall 23 to a rectangular frame. The housing 11 may also be formed by integrally molding the pair of first walls 21, the pair of second walls 22, and the third wall 23.

The tray 12 has a flat panel section 31, a rectangular frame-shaped rear wall section 32 provided on the rear end side of the panel section 31, a pair of storage sections 33 formed on both ends of the panel section 31 in the left-right direction, and a pair of arms 34 provided on each storage section 33.

The upper surface of the panel portion 31 increases in height at least from the center toward the front. The upper surface of the panel portion 31 supports a main body portion 1011 that is located below the folded-back portion 1050 of the bag 1000 (bag bundle 1001). As shown in FIG. 8, the panel portion 31 has a plurality of ribs 311, a first stopper 312, and a second stopper 313 on the lower surface facing the lower first wall portion 21.

The rib 311 extends along the front-rear direction of the underside of the panel portion 31. The first stopper 312 is a protrusion that protrudes downward from the underside of the panel portion 31 and is engageable with the first engagement portion 211.

The second stopper 313 is provided, for example, in pairs. The second stopper 313 includes a shaft portion 3131, a stopper body 3132 rotatably supported by the shaft portion 3131, a biasing member 3133 that biases the stopper body 3132, and a regulating portion 3134 that regulates the range of rotation of the stopper body 3132. The stopper body 3132 has an engagement protrusion 3135 at the front end with which the second engagement portion 212 engages.

The biasing member 3133 constantly biases the stopper body 3132 in a direction in which the opposing engagement protrusions 3135 of the pair of stopper bodies 3132 approach each other. The biasing member 3133 is, for example, a torsion spring. The restricting portion 3134 restricts the movement of the stopper body 3132 in a direction in which the engagement protrusions 3135 approach each other at a position where the second engagement portion 212 can engage with the engagement protrusions 3135 of the pair of stopper bodies 3132 each biased by the biasing member 3133.

The second stopper 313 and the second engagement portion 212 that engages with the second stopper 313 are positioned such that the rear ends of the pair of stopper bodies 3132 are exposed to the outside from the housing 11 when the tray 12 is located in the second position.

The rear wall portion 32 is formed in a rectangular frame shape to form an opening 321. The left and right width of the opening 321 is set to be equal to or greater than the width of the bag 1000. The top and bottom width of the opening 321 is set to be equal to or greater than the thickness of the bag bundle 1001. In other words, the opening 321 is set to an opening shape that allows the bag bundle 1001 to be inserted when the bag 1000 is inserted into the tray 12 and held by the holding member 13.

The storage sections 33 are provided on the left and right edges of the panel section 31. The storage sections 33 form the side walls of the tray 12. The storage sections 33 store part of the speed change mechanism 14. As shown in Figures 5, 8, and 9, the storage section 33 includes a slit 331 formed in the bottom wall and a first rail 332 formed in the side wall facing the other storage sections 33.

As shown in FIG. 8, the slit 331 is a rectangular opening extending in the front-rear direction. The first rail 332 is a linear opening extending in the front-rear direction. As a specific example, as shown in FIG. 5 and FIG. 9, the first rail 332 extends in the front-rear direction and is inclined in the front-rear direction and the up-down direction so that the front is higher than the rear in the front-rear direction.

One end of the arm 34 is rotatably supported behind the first rail 332 of the storage section 33. As shown in FIG. 4, the arm 34 is provided, for example, behind the first rail 332 and has a central shaft 341 supported by the storage section 33. The arm 34 can rotate around the central shaft 341, which serves as the center of rotation.

The arm 34 is formed long in one direction and has a second rail 342 that opens in the center along the longitudinal direction of the arm 34. The second rail 342 extends along the longitudinal direction of the arm 34 from one end (center axis 341) to the other end (forward), and is inclined at one end. Specifically, the arm 34 is in a position where the second rail 342 is aligned with the first rail 332 while the tray 12 is moving from the first position to the second position. The inclination direction of one end of the second rail 342 is a direction in which the arm 34 is inclined upward from the other end side toward the one end when the arm 34 extends in the front-rear direction, in other words, a direction in which the arm 34 is inclined backward from the other end side toward the one end when the arm 34 extends in the up-down direction.

Such a tray 12 can be inserted into the housing 11 and moved in the front-rear direction (one direction). The tray 12 moves in the front-rear direction within the housing 11, for example, between a first position and a second position. The first position is a position where the bag 1000 housed in the housing 11 and held by the holding member 13 within the tray 12 faces the removal opening 231, as shown in Figs. 1 and 2. The second position is a position where the tray 12 is pulled out from the housing 11, a part of the front of the tray 12 is placed within the housing 11, and the bag bundle 1001 is replenished to the holding member 13 within the tray 12, as shown in Fig. 12.

In the first position, the first stopper 312 of the tray 12 engages with the first engagement portion 211 of the housing 11. In the second position, the pair of second stoppers 313 of the tray 12 engage with the second engagement portion 212.

In the first position, the arm 34 is in a first posture in which the tip is located above the central axis 341 and extends forward, as shown in FIG. 9. In other words, in the first position, the arm 34 is in a first posture in which it extends at an upward incline from the rear side of the tray 12 toward the front side. That is, when the arm 34 is in the first posture midway from the first position to the second position, one end of the second rail 342 is located above the central axis 341.

In the second position, the arm 34 assumes a second posture in which the tip is positioned rearward of the central axis 341 and extends upward, as shown in FIG. 10. In other words, in the second position, the arm 34 assumes a second posture in which the arm 34 extends from the lower side of the tray 12 toward the upper side, tilting rearward. That is, in the second position, one end of the second rail 342 of the arm 34 is positioned rearward of the central axis 341.

The holding member 13 is provided in the tray 12. The holding member 13 folds and holds the bag bundle 1001, which is a stack of multiple bags 1000. When the tray 12 is housed in the housing 11, the holding member 13 has an end facing the removal opening 231, so that the folded portion 1050 of the held bag 1000 faces the removal opening 231.

The holding member 13 includes a support portion 41, a hook 42, a first guide 43, a second guide 44, and a pressing portion 45.

As shown in FIG. 6, the support section 41 has a support plate 411 formed in a plate shape, and a shaft section 412 that supports the folded portion 1050 of the bag 1000 and is provided in front of the support plate 411. The shaft section 412 located in front of the support section 41 creates the folded portion 1050 when the bag 1000 is folded. The support section 41 supports the folded portion 1050 with the shaft section 412, and supports the area above the folded portion 1050 with the upper surface of the support plate 411. Specifically, the upper surface of the support plate 411 supports the main body section 1011 above the folded portion 1050, the pair of handles 1012, and the hanging section 1013.

The hook 42 is provided on the upper surface of the support part 41 and behind the support part 41. The hook 42 holds the hanging part 1013 of the bag 1000.

A pair of first guides 43 are provided in front of the support part 41. The pair of first guides 43 protrude in the left and right directions from the side parts of the support part 41. For example, the pair of first guides 43 are provided on the shaft part 412 of the support part 41. The first guide 43 is inserted into the first rail 332. The first guide 43 inserted into the first rail 332 is held movably along the first rail 332 by the side wall of the storage part 33 in which the first rail 332 is formed. The tip of the first guide 43 is disposed in the storage part 43 of the first rail 332. For example, the first guide 43 is formed in a rod shape that is long in one direction along the extension direction of the first rail 332. In addition, the longitudinal length of the first guide 43 is set shorter than the first rail 332 so that the first rail 332 can be moved by a predetermined distance.

A pair of second guides (guides) 44 are provided behind the support portion 41. For example, the pair of second guides 44 are provided on the support plate 411 of the support portion 41. The second guides 44 are formed, for example, in a cylindrical shape with a central axis extending in the left-right direction. The pair of second guides 44 protrude in the left-right direction from the sides of the support portion 41, respectively. The second guides 44 are inserted into the second rail 342. The second guides 44 inserted into the second rail 342 are held by the arm 34 so as to be movable along the second rail 342.

The pressing portion 45 is provided on the support plate 411 so as to be movable relative to the upper surface of the support plate 411 of the support portion 41. The pressing portion 45 moves between a position spaced apart from the support plate 411 and a position in contact with the support plate 411. The pressing portion 45 is a pressing portion that presses the bags on the support plate 411. The pressing portion 45, for example, presses a pair of handles 1012 of the bags 1000 of the bag bundle 1001 supported on the support portion 41 toward the support plate 411. For example, a pair of pressing portions 45 are provided at the left and right ends of the upper surface of the support plate 411.

In this type of holding member 13, within the tray 12, a pair of first guides 43 are movably held on the first rails 332 of a pair of storage sections 33 of the tray 12, and a pair of second guides 44 are movably held on the second rails 342 of a pair of arms 34.

When the tray 12 is moved relative to the housing 11, the speed change mechanism 14 moves the holding member 13 within the tray 12 at a speed faster than the movement speed of the tray 12. In other words, the speed change mechanism 14 transmits the movement of the tray 12 moving between the first position and the second position to the holding member 13, and moves the holding member 13 at a speed faster than the speed of the tray 12. When the tray 12 is in the first position, the speed change mechanism 14 positions the front edge of the holding member 13 opposite the removal opening 231, and when the tray 12 is in the second position, positions the holding member 13 in a position where a bag bundle 1001 of multiple bags 1000 can be replenished.

For example, a pair of speed change mechanisms 14 are provided. The speed change mechanisms 14 are disposed in the left and right storage sections 33 of the tray 12, respectively. As shown in FIG. 5, the speed change mechanism 14 is a gear mechanism that changes the speed of the transmitted movement by a gear ratio. The speed change mechanism 14 includes a first gear 51, a second gear 52, and a third gear 53.

The first gear 51 is provided on the housing 11. For example, the first gear 51 is a rack with multiple teeth arranged in a straight line. Hereinafter, the first gear 51 will be described as the first rack 51. The first rack 51 is provided on both ends of the lower first wall portion 21 of the housing 11 in the left-right direction. The pair of first racks 51 is set to a length equal to the movement distance of the tray 12 moving between the first position and the second position, for example. The first rack 51 is provided on the upper surface of the lower first wall portion 21 at a position facing the slit 331 formed in the storage portion 33 of the tray 12. The first rack 51 extends along the front-rear direction. In other words, the first rack 51 extends along the movement direction of the tray 12 in the housing 11, in other words the longitudinal direction of the slit 331, and further in other words the front-rear direction.

The second gear 52 is provided on the holding member 13 and is housed in the storage section 33. For example, the second gear 52 is a rack with multiple teeth arranged in a straight line. Hereinafter, the second gear 52 will be described as the second rack 52. The second rack 52 is fixed to the end of the first guide 43 of the holding member 13. The second rack 52 is set to a length that does not interfere with other members in the storage section 33 when the holding member 13 moves in the tray 12 between the first position and the second position and the first guide 43 moves on the first rail 332. Furthermore, the second rack 52 extends in the same direction as the extension direction of the first guide 43 in the storage section 33.

The third gear 53 is housed in the housing portion 33 and is rotatably held in the housing portion 33. The third gear 53 meshes with the first rack 51 and the second rack 52. The third gear changes the speed of movement transmitted from the first rack 51 to the second rack 52 by the gear ratio. The third gear 53 is, for example, a gear train made up of multiple gears. Hereinafter, the third gear 53 will be described as the third gear train 53.

As a specific example, the third gear train 53 includes a single driving gear 531, a single or multiple first driven gears 532, and a single or multiple second driven gears 533. In this embodiment, as shown in FIG. 4, a configuration in which two first driven gears 532 and two second driven gears are provided will be described. Note that the minimum number of second driven gears 533 is set to, for example, one less than the total number of driving gears 531 and first driven gears 532.

The drive gear 531 includes a first gear portion 5311 with a first pitch circle and a second gear portion 5312 with a second pitch circle. The first pitch circle of the first gear portion 5311 is formed with a larger diameter than the second pitch circle of the second gear portion 5312. A lower part of the first gear portion 5311 protrudes downward from the tray 12 through the slit 331 of the storage section 33. The lower part of the first gear portion 5311 protruding from the slit 331 meshes with the first rack 51. The second gear portion 5312 meshes with the second rack 52.

One of the two first driven gears 532 meshes with the two second driven gears 533 and also meshes with the second rack 52. The two first driven gears 532 have a plurality of teeth set on a third pitch circle that is smaller in diameter than the first pitch circle. The third pitch circles of the two first driven gears 532 may be set to the same diameter or different diameters. The third pitch circle may be set to the same diameter as the second pitch circle or different diameters. In this embodiment, an example is described in which the third pitch circles of the two first driven gears 532 are set to different diameters and are set to a smaller diameter than the diameter of the second pitch circle.

The other of the two first driven gears 532 meshes with one of the first driven gears 532 and also meshes with the second rack 52. In the following description, one of the first driven gears 532 is referred to as the first intermediate driven gear 5321, and the other second driven gear 533 is referred to as the first end driven gear 5322.

The first intermediate driven gear 5321 includes a third gear portion 5323 having a third pitch circle and a fourth gear portion 5324 having a fourth pitch circle. The third pitch circle of the third gear portion 5323 is set to a larger diameter than the fourth pitch circle of the fourth gear portion 5324. The third gear portion 5323 meshes with the second rack 52. The fourth gear portion 5324 meshes with one of the second driven gears 533.

The first end driven gear 5322 has a plurality of teeth formed on a third pitch circle. Here, the third pitch circle of the first end driven gear 5322 is set to a smaller diameter than the third pitch circle of the third gear portion 5323 of the first intermediate driven gear 5321, but may be the same diameter.

The second driven gear 533 meshes with the drive gear 531 and the first driven gear 532, or with the first driven gears 532. As a specific example, one of the two second driven gears 533 meshes with the drive gear 531 and the first intermediate driven gear 5321. The other of the two second driven gears 533 meshes with the first intermediate driven gear 5321 and the first end driven gear 5322.

The pitch circle of the second driven gear 533 is appropriately set according to the pitch circles of the primary and secondary gears and the speed ratio of the rotational speed transmitted from the primary gear to the secondary gear.

Such a speed change mechanism 14 is arranged in the storage section 33 so that the first pitch circle of the first gear portion 5311 of the drive gear 531 overlaps with the pitch line of the first rack 51. In addition, the speed change mechanism 14 is arranged in the storage section 33 so that the second pitch circle of the second gear portion 5312 of the drive gear 531, the third pitch circle of the third gear portion 5323 of the first intermediate driven gear 5321, and the third pitch circle of the first end driven gear 5322 overlap with the pitch line of the second rack 52.

When the tray 12 is moved in the front-rear direction in the housing 11, the third gear train 53 of the speed change mechanism 14 also moves. When the third gear train 53 moves, the drive gear 531 moves relative to the first rack 51 fixed to the housing 11, and the drive gear 531 rotates. When the drive gear 531 rotates, the rotation of the drive gear 531 is transmitted to the second driven gear 533 on one side, the first intermediate driven gear 5321, the second driven gear 533 on the other side, and the first end driven gear 5322.

When the drive gear 531 rotates, the second rack 52 meshing with the drive gear 531 moves along the first rail 332. Here, the third gear train 53 has a speed change ratio set so that the moving speed of the second rack 52 is faster than the moving speed of the tray 12. That is, the rotation speeds of the second gear portion 5312 of the drive gear 531, the first intermediate driven gear 5321, and the first end driven gear 5322 are set to a speed faster than the moving speed of the tray 12. Therefore, the speed change mechanism 14 moves the second rack 52 at a speed faster than the moving speed of the tray 12 in accordance with the movement of the tray 12. And the support portion 41 to which the second rack 52 is fixed moves in accordance with the movement of the second rack 52.

Next, an example of a method of using the bag storage device 1 configured in this manner will be described with reference to Figures 5, 9 to 15. As a specific example, an example of a method of refilling the bags 1000 when the remaining amount of bags 1000 stored in the bag storage device 1 has run out will be described.

First, a worker such as a store clerk who is replenishing the bags 1000 in the bag storage device 1 confirms that the shaft portion 412 of the support portion 41 is exposed from the removal opening 231 of the bag storage device 1 and that there are no bags 1000 inside the bag storage device 1, and then begins the task of replenishing the bags 1000.

The worker places his/her fingers on the rear wall portion 32 of the tray 12, which is in the first position shown in FIG. 5, and pulls out the tray 12 toward the rear of the bag storage device 1. When the worker pulls out the tray 12, the engagement between the first engagement portion 211 of the housing 11 and the first stopper 312 of the tray 12 is released. This causes the tray 12 to move rearward, as shown in FIG. 9.

As the tray 12 moves rearward, the drive gear 531 of the speed change mechanism 14 rotates through the first rack 51, and the second rack 52, which is fixed to the holding member 13, moves rearward. The holding member 13 has the first guide 43 movably held on the first rail 332, and the second guide 44 held on the second rail 342. Thus, the holding member 13 moves from the front side to the rear within the tray 12 along the first rail 332, from the position shown in FIG. 5 to the position shown in FIG. 9.

When the operator further pulls out the tray 12 toward the second position, the holding member 13 moves further rearward from the position shown in FIG. 9. At this time, the second guide 44 of the holding member 13 presses rearward the rear end (one end) of the second rail 342 of the arm 34. When the arm 34 is in the first position midway from the first position to the second position, one end of the second rail 342 is positioned above the central axis 341. Therefore, the arm 34, with one end of the second rail 342 pressed by the second guide 44, rotates about the central axis 341 to move from the first position in FIG. 9 to the second position in FIG. 10.

When the operator pulls out the tray 12 from the middle of the way to the second position to the second position, the second engagement portion 212 of the housing 11 engages with the regulating portion 3134 of the second stopper 313, and the movement of the tray 12 is restricted. At this time, the second guide 44 of the holding member 13 rotates the arm 34 to the second position as shown in FIG. 10. Then, when the tray 12 is pulled out to the second position, the second guide 44 of the holding member 13 moves along the second rail 342 of the arm 34 in the second position as shown in FIG. 11. Therefore, the holding member 13 is erected so as to be inclined slightly backward.

At this time, the holding member 13 is in a position in which the hook 42 is located above the support plate 411, as shown in Figures 11 to 15. By pulling out the tray 12 to the second position in this way, the bag storage device 1 is in a state in which the tray 12 and the holding member 13 can be replenished with bags 1000.

Next, as shown in FIG. 12, the worker positions the bag stack 1001 to be replenished so that the width direction of the main body portion 1011 of the bag 1000 is the left-right direction. Then, the worker inserts the pair of handles 1012 side into the openings 321 of the rear wall portions 32 of the pair of trays 12. The worker also moves the pressing portion 45 away from the support plate 411.

As shown in FIG. 13, the worker inserts the hook 42 into the hole 1014 of the hanging portion 1013 of the multiple bags 1000 in the bag bundle 1001, and hangs the bags 1000 by the hook 42. Then, as shown in FIG. 14, the worker moves the pressing portion 45 toward the support portion 41, and the pressing portion 45 presses the pair of handles 1012. At this time, the worker holds the pair of handles 1012, for example, and extends the handles 1012 upward as shown in FIG. 14.

When the pair of handles 1012 are pressed by the pressing portion 45, the worker releases the grip of the handles 1012. This causes the tips of the handles 1012 to bend downward, as shown in FIG. 15. Through these steps, the bag bundle 1001 is set on the holding member 13.

Next, the operator pushes the rear wall portion 32 of the tray 12 in the second position shown in FIG. 11 to move the tray 12 toward the front of the bag storage device 1 and insert the tray 12 into the housing 11. This causes the tray 12 to move forward from the second position toward the first position. As the tray 12 moves forward, the drive gear 531 of the speed change mechanism 14 is rotated by the first rack 51, and the second rack 52 fixed to the holding member 13 moves forward.

The first guide 43 of the holding member 13 is held movably on the first rail 332, and the second guide 44 is held on the second rail 342. Thus, in the holding member 13, the second guide 44 moves forward and the first guide 43 moves downward from the position shown in FIG. 11 to the position shown in FIG. 10. This changes the inclination angle of the support part 41 from the position of the support part 41 in FIG. 11 to the position of the support part 41 in FIG. 10. Then, the second guide 44 moves to one end of the second rail 342 of the arm 34 in the second position.

Furthermore, with the second guide 44 positioned at one end of the second rail 342 of the arm 34 in the second position, the operator inserts the tray 12 toward the first position. At this time, the second guide 44 of the holding member 13 presses the rear end (one end) of the second rail 342 of the arm 34 forward and downward. Also, at this time, in the second position of the arm 34, one end of the second rail 342 is behind the central axis 341. Therefore, the arm 34, with one end of the second rail 342 pressed by the second guide 44, rotates around the central axis 341 to change from the second position of FIG. 10 to the first position of FIG. 9.

When the worker inserts the tray 12 into the housing 11 from the middle of the path from the second position to the first position, the drive gear 531 of the speed change mechanism 14 rotates by the first rack 51 as the tray 12 moves forward, and the second rack 52 fixed to the holding member 13 moves forward. Thus, the holding member 13 moves from the rear side to the front side in the tray 12 along the first rail 332 from the position shown in FIG. 5 to the position shown in FIG. 9. Then, when the worker inserts the tray 12 to the first position, the first engagement portion 211 of the housing 11 engages with the first stopper 312 of the tray 12, and the tray 12 is positioned at the first position. When the tray 12 is positioned at the first position, the folded portion 1050 of the bag bundle 1001 arranged on the shaft portion 412 of the support portion 41 faces the removal opening 231, and the bags 1000 can be removed from the removal opening 231. Through these steps, the bags 1000 are replenished in the bag storage device 1.

According to the bag storage device 1 configured in this manner, the tray 12 is moved relative to the housing 11 between the first position and the second position, and the holding member 13 can be moved by the speed change mechanism 14. When the tray 12 is in the first position, the holding member 13 is located in front of the tray 12, and faces the removal opening 231. When the tray 12 is in the second position, the holding member 13 is located behind the tray 12, and is in a position where the bags 1000 can be replenished.

Therefore, the bag storage device 1 can move to a position where it is easy to set the bag 1000 on the holding member 13 simply by pulling the tray 12 out of the housing 11 to the second position. Also, the bag storage device 1 can position the bag 1000 set on the holding member 13 at a position where it can be removed from the removal opening 231 by inserting the tray 12 into the housing 11 to the first position. Therefore, the bag storage device 1 can easily set the bag 1000 on the tray 12. Also, the bag storage device 1 does not need to pull the tray 12 completely out of the housing 11, and does not need to move the holding member 13 separately relative to the tray 12. Therefore, the bag storage device 1 can reduce the number of operations required to set the bag 1000.

In addition, when the tray 12 is located in the second position, the holding member 13 is exposed from the tray 12, which improves the ease with which an operator can set the bag 1000 on the holding member 13.

The speed change mechanism 14 transmits the movement of the tray 12 to the movement of the holding member 13, and changes the movement speed of the holding member 13 to a speed faster than the movement speed of the tray 12. When the tray 12 is moved to the first position and the second position, the speed change mechanism 14 can move the holding member 13 within the tray 12. Thus, when the tray 12 moves between the first position and the second position, the holding member 13 faces the removal opening 231 at the first position of the tray 12. Furthermore, when the holding member 13 is exposed to the outside from the rear of the tray 12 at the second position, it is in a position that makes it easy to set the bag 1000.

Furthermore, when the tray 12 is in the second position, the holding member 13 has the support portion 41 standing upward and the hook 42 positioned upward. Therefore, when the bag 1000 is placed in the tray 12 and held by the holding member 13, the task of holding the hanging portion 1013 of the bag 1000 becomes easy.

The holding member 13 also presses the handle 1012 of the bag 1000 toward the support portion 41 with the pressing portion 45. This prevents the handle 1012 of the bag 1000 from bending. By pressing the handle 1012 with the pressing portion 45, when the bag 1000 is removed from the removal opening 231, the handle 1012 of the bag 1000 stacked with the removed bag 1000 can be prevented from popping out of the removal opening 231.

The tray 12 also has a first stopper 312 that engages with the first engagement portion 211 of the housing 11 in the first position. This allows the tray 12 to be positioned in the first position when inserted into the housing 11, so that the holding member 13 is positioned in a suitable position relative to the removal opening 231. Furthermore, because the first stopper 312 engages with the first engagement portion 211, the movement of the tray 12 is restricted by the engagement between the first stopper 312 and the first engagement portion 211 when the bag storage device 1 is lifted, etc. Thus, the bag storage device 1 can prevent the tray 12 from falling from the housing 11.

The tray 12 also has a second stopper 313 that engages with the second engagement portion 212 of the housing 11 in the second position. This restricts the tray 12, pulled out of the housing 11, from moving rearward from the second position. Therefore, the bag storage device 1 can hold the tray 12 in the second position, and the bag 1000 can be set without completely removing the tray 12 from the housing 11. This eliminates the need to completely remove the tray 12 from the housing 11, and also eliminates the need to secure a place to store the tray 12.

When the tray 12 is to be completely removed from the housing 11, the rear ends of the pair of stopper bodies 3132 of the pair of second stoppers 313 are operated in a direction in which they approach each other. This causes the restricting portions 3134 of the pair of second stoppers 313 to move apart, so that the tray 12 can be completely pulled out from the housing 11 by pulling out the tray 12.

As described above, the bag storage device 1 according to this embodiment makes it easy to replenish the bags 1000.

The embodiment is not limited to the above embodiment, and the components can be modified without departing from the spirit of the embodiment. For example, the bag storage device 1 may have a configuration that guides the position of the bag 1000 held by the holding member 13 in the left-right direction (width direction of the bag 1000) and fixes the bag 1000 so that it does not move in the left-right direction.

For example, the bag storage device 1 according to the second embodiment will be described with reference to Figs. 16 to 18. Note that among the components of the bag storage device 1 according to the second embodiment, components similar to those of the bag storage device 1 according to the first embodiment described above are given the same reference numerals, and detailed descriptions thereof will be omitted. Also, Figs. 16 to 18 show only the essential components.

Figure 16 is an explanatory diagram showing the configuration of the main components of the bag storage device 1 according to the second embodiment, including the tray 12, the holding member 13, the pair of central guides 16, the pair of moving mechanisms 17, the pair of bag guides 18, and the bag 1000. Figures 17 and 18 are explanatory diagrams that show a schematic configuration of the central guide 16 and the moving mechanism 17, and an example of the operation. In Figure 16, the solid lines show the state in which the pair of central guides 16 are close to each other, and the two-dot chain lines show the state in which the pair of central guides are separated from each other.

The bag storage device 1 includes a housing 11, a tray 12, a holding member 13, a speed change mechanism 14, a central guide 16, a moving mechanism 17, and a bag guide 18. The bag storage device 1 according to the second embodiment includes the bag storage device 1 according to the first embodiment described above, and further includes the central guide 16, the moving mechanism 17, and the bag guide 18. Therefore, in the description of the bag storage device 1 according to the second embodiment, only the central guide 16, the moving mechanism 17, and the bag guide 18 will be described, and the description of the other components will be omitted.

The central guides 16 are provided on the left and right sides of the support portion 41. The opposing surfaces of the pair of central guides 16 extend in the front-rear direction. The central guides 16 are arranged on the panel portion 31 of the tray 12 with a gap between them and the upper surface of the panel portion 31. The central guides 16 move in the left-right direction toward and away from each other. Movement of the central guides 16 in directions other than the left-right direction is restricted by the configuration of the central guides 16, the tray 12, and the restricting portions provided on the holding member 13, etc.

The moving mechanism 17 moves the pair of central guides 16 closer to and farther apart in the left-right direction as the tray 12 moves in the front-rear direction. As a specific example, the moving mechanism 17 includes a first operating rod 61, a second operating rod 62, a biasing member 63, a first operating unit 64, and a second operating unit 65. As the tray 12 moves, the moving mechanism 17 has the first operating unit 64 operating the first operating rod 61 and the second operating unit 65 operating the second operating rod 62.

The first operating rod 61 has a first rotation axis 611. The first operating rod 61 rotates around the central axis 611 by operation of the first operating unit 64. The first operating rod 61 is rotatably supported by the tray 12 or the holding member 13. When the first operating rod 61 is operated and rotated by the first operating unit 64, it rotates the second operating rod 62.

The second operating bar 62 rotatably supports the central guide 16. The second operating bar 62 has a second rotation shaft 621. The second operating bar 62 is rotatably supported on the tray 12 or the holding member 13. When the second operating bar 62 is operated by the first operating unit 64, the second operating bar 62 rotates around the second rotation shaft 621 in a direction in which the pair of central guides 16 move apart. When the second operating bar 62 is operated and rotated by the second operating unit 65, it rotates around the second rotation shaft 621 in a direction in which the pair of central guides 16 move closer to each other.

The biasing member 63 biases the second operating bar 62 in the rotational direction around the second rotation axis 621 where the pair of central guides 16 approach each other. As a specific example, the biasing member 63 is a tension spring. The biasing member 63 biases the second operating bar 62 in the direction where the pair of central guides 16 approach each other while the pair of central guides 16 move away from the position where they are close enough to guide the bag 1000 to a predetermined distance. Then, when the pair of central guides 16 move away from each other by the predetermined distance, the biasing member 63 reverses the biasing direction and biases the second operating bar 62 in the rotational direction around the second rotation axis 621 where the pair of central guides 16 move away from each other.

The first operating unit 64 is provided inside the housing 11. The first operating unit 64 comes into contact with the first operating rod 61 and operates the first operating rod 61 while the tray 12 is moving from the first position to the second position.

The second operating unit 65 is provided inside the housing 11. The second operating unit 65 comes into contact with the second operating bar 62 and operates the second operating bar 62 while the tray 12 is moving from the second position to the first position.

As shown in FIG. 16, a pair of bag guides 18 are provided on the support portion 41, for example, on the left and right sides of the shaft portion 412. The bag guide 18 includes a guide portion 71 that extends in the left and right directions, and a guide plate 72 that can move along the guide portion 71.

The guide portion 71 guides the guide plate 72, for example, in the left-right direction. The guide plate 72 can be manually moved along the guide portion 71. The pair of guide plates 72 also regulate the movement positions of the pair of central guides 16 in the direction in which they approach each other. That is, as shown in FIG. 16, the pair of guide plates 72 face the pair of central guides 16 in the left-right direction. The pair of guide plates 72 guide the position of the central guide 16 so that the pair of approaching central guides 16 can press the bag 1000 with a predetermined pressing force against the bag 1000 due to the movement of the tray 12.

For example, the main surface of the central guide 16 facing the guide plate 72 is partially recessed, and the guide plate 72 is placed in the recess of the central guide 16. This makes the main surfaces of the guide plate 72 and the central guide 16 facing the bag 1000 flush with each other.

According to the bag storage device 1 configured in this manner, when the tray 12 is moved from the first position to the second position relative to the housing 11, the first operating unit 64 operates the first operating rod 61. The first operating rod 61 rotates the second operating rod 62 against the bias of the biasing member 63, and the movement mechanism 17 changes from the state shown in FIG. 17 to the state shown in FIG. 18. The movement mechanism 17 separates the pair of central guides 16, and the width of the pair of central guides 16 increases. Therefore, when the bag 1000 is set on the holding member 13 of the tray 12 in the second position, a space for setting the bag 1000 can be secured between the pair of central guides 16. In addition, the biasing member 63 reverses the direction in which it biases the second operating rod 62, so that the pair of central guides 16 is maintained in a separated state.

Furthermore, according to the bag storage device 1, when the tray 12 is moved from the second position to the first position relative to the housing 11, the second operating unit 65 operates the second operating rod 62. At this time, the second operating rod 62 resists the bias of the biasing member 63 immediately after the start of operation, and then rotates due to the biasing member 63 being biased by the biasing member 63 with the biasing direction reversed during operation. Therefore, the movement mechanism 17 changes from the state shown in FIG. 18 to the state shown in FIG. 18, and the pair of central guides 16 approach each other.

As a result, the pair of central guides 16 press against the sides of the bag bundle 1001 held by the holding member 13, guiding the position of the bag bundle 1001. At the same time, the second operating rod 62 rotates the first operating rod 61. At this time, the second operating rod 62 is constantly urged by the urging member 63 in a direction in which the pair of central guides 16 approach each other and guide the sides of the bag bundle 1001. In this way, the central guide 16 and the moving mechanism 17 can appropriately align the bags 1000 in the left-right direction with respect to the removal opening 231.

Therefore, in addition to the effects of the bag storage device 1 according to the first embodiment described above, the bag storage device 1 can align the bag bundle 1001 (bags 1000) in the left-right direction of the support portion 41 using a pair of central guides 16.

The movement mechanism 17 is driven by the movement of the tray 12. Therefore, the central guide 16 can be moved closer to or farther away by the worker moving the tray 12 in one direction. Therefore, when replenishing the bags 1000, the bag storage device 1 does not require the worker to operate the central guide 16, reducing the number of operations.

In addition, the bag guide 18 can adjust the position of the pair of central guides 16 relative to the bag 1000, so the contact of the central guides 16 with the bag 1000 can be adjusted to match the size of the bag 1000.

As described above, the bag storage device 1 according to the second embodiment makes it easy to replenish the bags 1000.

Furthermore, the present invention is not limited to the above-mentioned embodiments as they are. In the above-mentioned examples, the bag storage device 1 is configured to move the holding member 13 relative to the tray 12 using a speed change mechanism 14 that uses various gears and racks, but is not limited to this. The speed change mechanism 14 is only required to be able to move the holding member 13 within the tray 12 by the movement of the tray 12, and to move the holding member 13 at a speed faster than the movement speed of the tray 12. For example, the speed change mechanism 14 may be composed of only rotating gears without using racks, or may be composed of a combination of belts, pulleys, etc. without using gears.

In the above example, the bag storage device 1 is provided with a pair of central guides 16, a pair of moving mechanisms 17, and a pair of bag guides 18 as the second embodiment, but is not limited to this. For example, the bag storage device 1 may be configured to have a pair of central guides 16 and a pair of moving mechanisms 17, but not a pair of bag guides 18. Also, the bag storage device 1 may be configured to have a pair of bag guides 18 and manually guide the bags 1000, without having a pair of central guides 16 and a pair of moving mechanisms 17. Also, the pair of moving mechanisms 17 is not limited to the above example, as long as it is configured to be able to move the pair of central guides 16 depending on the position of the tray 12.

In the above example, the bag storage device 1 has been described as having a configuration in which the housing 11 has the removal opening 231 for removing the bag 1000, but this is not limited to the above. For example, the bag storage device 1 may have the opening 321 as the removal opening for the bag 1000. That is, the front surface of the bag storage device 1 may be on the rear wall portion 32 side of the tray 12, and the opening 321 may be the removal opening for the bag 1000. Also, for example, both the removal opening 231 and the opening 321 may be the removal opening for the bag 1000.

The bag storage device 1 may also be configured such that the housing 11 does not have an outlet 231, and only the opening 321 in the rear wall 32 of the tray 12 serves as the outlet for the bags 1000. In a bag storage device 1 configured in this way, the rear wall 32 side of the tray 12 serves as the front side, and the opening 321 serves as the outlet. In addition, the bag storage device 1 can move the tray 12 from the front side of the bag storage device 1 to the second position to set the bag bundle 1001.

According to at least one of the embodiments of the bag storage device described above, the remaining amount of bags can be visually confirmed.

Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
