The supply unit 42, the display device 43, the input device 44, the audio output unit 45, and the payment unit 46 are all peripheral devices of the management device 41 and are connected to the management device 41.

  The management device 41 receives the product information transmitted from the shopping basket 92. The “product information” here is information (product identification code) for identifying the product 91 and is, for example, a JAN (Japanese Article Number) code used in Japan. Furthermore, the management device 41 is configured to be able to communicate with a store terminal including, for example, a POS (Point Of Sales) terminal. The management device 41 can perform a checkout process for the product 91 based on the product information received from the shopping basket 92. The management device 41 is electrically connected to the bag supply device 2 and the bagging device 3 and is configured to be able to control the bag supply device 2 and the bagging device 3.

  The supply unit 42 is a device that supplies a specific commodity (for example, tobacco) to a customer. The display device 43 is a device that performs various displays for customers. The input device 44 is a device that accepts a customer's operation by, for example, gesture detection. Further, the input device 44 includes a microphone, and has a function of performing voice recognition and semantic analysis processing on a voice signal input to the microphone. Therefore, the customer can also perform voice operations (voice input). The audio output unit 45 is a device that includes a speaker and presents various types of information to customers by audio.

  That is, the sales system 4 uses the display device 43, the input device 44, and the voice output unit 45 as a user interface, thereby presenting various information to the customer by display or voice, and customer operations (including voice input). Can be accepted. However, the presentation of information by the sales system 4 may be realized by at least one of display and sound, may be realized by either display or sound, or is realized by a combination of display and sound. May be.

  The shopping basket 92 incorporates a circuit block including a battery and various circuits and modules that operate by receiving power supplied from the battery. The shopping basket 92 not only simply stores the product 91, but also has a function of communicating with the sales system 4 (management device 41) and a function of reading product information of the product 91. The shopping basket 92 reads product information using, for example, a bar code reader or an image sensor. Thereby, the shopping basket 92 can read the product information from the product 91 and transmit it to the sales system 4 while accommodating the product 91 picked up in the store by the customer.

  The bagging device 3 can pack the product 91 in the shopping basket 92. In other words, the customer puts the product 91 picked up in the store into the shopping basket 92 and places the product 91 together with the shopping basket 92 in the bagging space S <b> 1 described later, thereby causing the bagging apparatus 3 to pack the product 91. be able to. Therefore, the customer does not need to take out the product 91 from the shopping basket 92 for bagging, and can easily pack the product 91 using the bagging device 3. When a plurality of products 91 are accommodated in the shopping basket 92, the bagging device 3 can pack the plurality of products 91 in a lump. In the present embodiment, the management device 41 operates in conjunction with the sales system 4 so that the product 91 is packaged while the customer is paying for the product 91 in the sales system 4. 3 is controlled. For example, the bagging device 3 starts bagging of the product 91 with a trigger that the checkout process is started or completed in the sales system 4.

  The bag supply device 2 takes out the bags 7 one by one from the bag storage case 1 stocking a plurality of bags 7 and supplies the taken bags 7 to the bagging device 3 as “target bags”. In the present embodiment, the management device 41 controls the bag supply device 2 in conjunction with the bagging device 3 so that one bag 7 is always set (arranged) in the bagging device 3. In other words, the bagging device 3 is configured to perform bagging using one bag 7 supplied from the bag supply device 2, and each time the bagging device 3 performs bagging once. The new bags 7 are supplied from the bag supply device 2 to the bagging device 3 one by one in preparation for the next bagging. In other words, the bag supply device 2 starts the supply of the bag 7 to the bagging device 3 by using the completion of bagging by the bagging device 3 as a trigger.

  The bag storage case 1 is configured to store a plurality of bags 7 together. The bag storage case 1 is used in a state of being stored in a predetermined case storage space S2 (see FIG. 1). That is, the bag storage case 1 in a state where at least one bag 7 is stored is arranged in the case storage space, so that the bag supply device 2 can take out the bag 7 from the bag storage case 1. . The bag storage case 1 can be taken out from the case storage space S2, and the replenishment of the bag 7 to the bag storage case 1 is performed with the bag storage case 1 taken out from the case storage space S2.

  By the way, as shown in FIG. 3, the shopping support system 100 is provided around, for example, one counter stand 8 installed in a cash register counter of a store, except for the shopping basket 92. That is, around the counter stand 8, a bag storage case 1, a bag supply device 2, a bagging device 3, and a sales system 4 are provided. A plurality of such counter stands 8 may be installed for one store.

  In the example of FIG. 3, the bag storage case 1, the bag supply device 2, the bagging device 3, and the management device 41 are built in the counter base 8. Here, the bag storage case 1 is stored in a case storage space S2 set inside the counter table 8 in a state where it can be taken out.

  In the counter table 8, a recess 82 is formed that opens at a substantially central portion in the width direction (left-right direction) of the upper surface 81. The recess 82 forms a bagging space S1. In the example of FIG. 3, the shopping basket 92 is placed in the recess 82 (that is, the bagging space S <b> 1). However, the shopping basket 92 is held in a hand or placed on a cart when the customer moves in the store. Because it is used, it is not fixed in place. A collection device 83 that collects the shopping basket 92 is disposed in the back of the recess 82 when the counter table 8 is viewed from the front. Below the recess 82, the bagging device 3 is installed.

  Here, the shopping basket 92 is configured, for example, so that the bottom plate can slide. As a result, the bottom of the shopping basket 92 can be opened and closed, and the product 91 accommodated in the shopping basket 92 can be discharged from the bottom of the shopping basket 92. Further, the bottom surface of the recess 82 is configured by an openable / closable shutter 821 (see FIG. 1). In the state where the shutter 821 is opened, the placement surface 311 of the bagging device 3 located below the recess 82 is exposed from the bottom surface of the recess 82. Therefore, if the bottom plate of the shopping basket 92 placed in the bagging space S1 is opened with the shutter 821 opened, the product 91 in the shopping basket 92 is placed on the placement surface 311 of the bagging apparatus 3. Discharged. Details will be described in the column “(2.4) Bagging Device”, but the bagging device 3 packs the product 91 placed on the placement surface 311. Therefore, the product 91 in the shopping basket 92 can be packaged.

  The bag supply device 2 is arranged on the right side of the bagging device 3 when the counter table 8 is viewed from the front. The bag storage case 1 (case storage space S2) is arranged on the right side of the bag supply device 2 when the counter table 8 is viewed from the front.

  The supply unit 42 is suspended from the ceiling so as to be positioned above the counter base 8. The display device 43 is fixed to the lower surface of the supply unit 42 and is configured to project an image on a screen by, for example, a projection mapping technique. Here, the display device 43 projects an image on an area on the right side of the recess 82 of the upper surface 81 of the counter table 8 when the counter table 8 is viewed from the front. That is, the area on the right side of the recess 82 in the upper surface 81 of the counter table 8 is the screen of the display device 43. The input device 44 is installed on the upper surface 81 of the counter table 8 and at the back of the screen when the counter table 8 is viewed from the front. The input device 44 is integrally provided with an audio output unit 45.

  Moreover, the positional relationship and the shape of each part of the shopping support system 100 described above are merely examples, and can be changed as appropriate. For example, the bagging device 3 and the recess 82 may be disposed at one end portion (left end portion or right end portion) of the counter base 8 in the width direction (left-right direction). Further, the formation of the recess 82 in the counter table 8 is not essential for the shopping support system 100. For example, a bagging space S1 may be set on the upper surface 81 of the counter table 8.

  In the following description, it is assumed that the counter table 8 is installed in a direction in which the upper surface 81 of the counter table 8 is a horizontal plane unless otherwise specified. That is, the direction orthogonal to the upper surface 81 of the counter table 8 is the vertical direction (vertical direction). Further, hereinafter, the width direction (left-right direction) of the counter base 8 is referred to as “X-axis direction”, the depth direction (front-rear direction) is referred to as “Y-axis direction”, and the vertical direction (vertical direction) is referred to as “Z-axis direction”. To do. That is, the X-axis direction, the Y-axis direction, and the Z-axis direction are directions orthogonal to each other. Further, when distinguishing the positive direction and the negative direction in the Z-axis direction, the positive direction in the Z-axis direction is “upward” and the negative direction in the Z-axis direction is “ It is described as “downward”. Similarly, when distinguishing the positive direction and the negative direction in the X-axis direction, the positive direction in the X-axis direction is “right” and the negative direction in the X-axis direction is based on the direction in FIG. Is described as “left”. Similarly, when distinguishing the positive direction and the negative direction in the Y-axis direction, the positive direction in the Y-axis direction will be described as “front”, and the negative direction in the Y-axis direction will be described as “rear”. The arrows indicating the “X-axis direction”, “Y-axis direction”, and “Z-axis direction” in the drawings are merely shown for explanation, and do not involve an entity. However, these directions are not intended to limit the direction when the shopping support system 100 is used. For example, the shopping support system 100 is used in a state where the upper surface 81 of the counter table 8 is slightly inclined with respect to the horizontal plane. Also good.

(2.2) Bag Storage Case Next, the bag storage case 1 will be described in more detail with reference to FIGS.

  The bag storage case 1 stores a bag bundle 70 having a plurality of bags 7 in a state of being overlapped with each other in the first direction which is the thickness direction. The bag bundle 70 is connected to at least a part of the plurality of bags 7 in a state where the plurality of bags 7 are stacked. Thereby, it is possible to handle a plurality of bags 7 in an integrated state without the individual bags 7 being separated. That is, the bag storage case 1 does not store a plurality of bags 7 individually, but can store a plurality of bags 7 as a bag bundle 70 in which a plurality of bags 7 are bundled. Although the number of bags 7 included in the bag bundle 70 can be changed as appropriate, the bag bundle 70 is configured by bundling 100 bags 7 as an example.

  The bag storage case 1 includes a case main body 11 and a holding portion 12 (see FIG. 5B). The case main body 11 stores the bag bundle 70. The holding unit 12 holds the bag bundle 70 in the case body 11.

  Here, the case main body 11 has a central portion 113, a first end surface 111, a second end surface 112, and an outlet 13. The center portion 113 is located at the center in the second direction intersecting the first direction in the case body 11. The first end surface 111 and the second end surface 112 are located at both ends in the second direction. In the state where the bag storage case 1 is stored in the case storage space S2, the X-axis direction (left-right direction) is the first direction and the Z-axis direction (up-down direction) is the second direction. The “first direction” will be described as the X-axis direction, and the “second direction” will be described as the Z-axis direction. Furthermore, in the present embodiment, the lower end surface of the case body 11 is the first end surface 111 and the upper end surface is the second end surface 112.

  The take-out port 13 is an opening for taking out each of the plurality of bags 7 and opens at a position between the center portion 113 and the first end surface 111 in the Z-axis direction of the case body 11. On the other hand, the holding part 12 is located between the center part 113 and the second end face 112 in the Z-axis direction of the case body 11. That is, as shown in FIG. 5A, when the case main body 11 is divided into two in the Z-axis direction at the central portion 113, the outlet 13 is located in the region Z1 on the first end surface 111 side, and the holding portion 12 is the second end surface. It is located in the region Z2 on the 112 side. In other words, the outlet 13 and the holding part 12 are located on the opposite sides in the Z-axis direction with respect to the central part 113 of the case body 11.

  In the present embodiment, the case main body 11 further includes a body 114 and a cover 115. The body 114 and the cover 115 are made of synthetic resin, for example. The cover 115 forms a space for storing the bag bundle 70 between the body 115 and the body 114 in the X-axis direction. The body 114 and the cover 115 are combined in the X-axis direction to form the case body 11. Here, the cover 115 is configured to be openable and closable with respect to the body 114. That is, the cover 115 is configured to be movable between a closed position in which the bag bundle 70 is accommodated with the body 114 and an open position in which the bag bundle 70 is opened. In the present embodiment, the case body 11 has a pair of hinge structures 14 at one end in the Y-axis direction, and the cover 115 is connected to the body 114 by the pair of hinge structures 14. Further, the case body 11 has a pair of lock structures 15 at the other end in the Y-axis direction, and the cover 115 can be held in the closed position by the pair of lock structures 15. Therefore, the case main body 11 has a so-called laterally open structure in which the cover 115 can be opened and closed with one end portion in the Y-axis direction as an axis. FIG. 5A shows a state where the cover 115 is in the closed position, and FIG. 5B shows a state where the cover 115 is in the open position.

  The outlet 13 is formed on one surface of the case body 11 in the X-axis direction. Here, an outlet 13 is formed on the right side surface of the case body 11. In the present embodiment, the dimension of the cover 115 in the Z-axis direction is set to be smaller than the dimension of the body 114 in the Z-axis direction, and the cover 115 covers the lower part of the body 114 (the end on the first end surface 111 side). It is combined with the body 114 so as not to cover. Therefore, the outlet 13 is opened below the cover 115 on one surface of the case body 11 in the X-axis direction.

  Here, the bag bundle 70 has a separation portion 701 that is detachably connected to the plurality of bags 7. In the present embodiment, the separation portion 701 is connected to the central portion of the bag mouth 71 in each bag 7. A cut line 702 for separating individual bags 7 from the separation portion 701 is formed between the separation portion 701 and each of the plurality of bags 7. On the cut line 702, processing such as perforation is performed so that the bag 7 can be easily separated along the cut line 702. Each of the plurality of bags 7 is preferably embossed on the surface. Thereby, a pair of adjacent bags 7 are easily separated from each other in the state of the bag bundle 70, and one bag 7 is easily taken out from the bag bundle 70. Furthermore, although mentioned later in detail, when the surface of the bag 7 is embossed, the suction of the bag 7 with the vacuum suction pad is facilitated.

  The holding part 12 holds the separation part 701 of the bag bundle 70, and is configured to release the holding of the bag 7 by separating each of the plurality of bags 7 from the separation part 701. . In this embodiment, the holding | maintenance part 12 has the pin 121 and the holder 122, as shown to FIG. 5B. The pin 121 protrudes from the surface of the body 114 that faces the cover 115. The receiver 122 is a disc-shaped member made of an elastic body such as synthetic rubber and having a hole formed in the center thereof, and is disposed on a surface of the cover 115 facing the body 114. When the pin 121 passes through the hole of the separation part 701, the bag bundle 70 is held by the holding part 12 by the separation part 701. Further, in a state where the cover 115 is in the closed position, the pin 121 is inserted into the hole of the receiving member 122, thereby preventing the separation portion 701 from falling off from the pin 121.

  In short, the holding part 12 holds the separation part 701 so that the separation part 701 is sandwiched between the holder 114 and the body 114. In FIG. 5B, the area | region pressed by the receiving tool 122 in the separation part 701 is shown with the dashed-two dotted line. Therefore, in the state where the cover 115 is opened, that is, in the state where the cover 115 is in the open position, the holding of the bag bundle 70 by the holding unit 12 is released, and the bag bundle 70 can be replaced or replenished. In addition, each of the plurality of bags 7 is connected to the separation part 701 via the cut line 702, and therefore, the individual bags by the holding part 12 are separated from the separation part 701 by the cut line 702. 7 is released.

  Here, as shown in FIG. 5B, the plurality of bags 7 in the bag bundle 70 are directed with the bag mouth 71 facing upward (positive direction in the Z-axis direction) and each bag mouth 71 being closed, It is stored in the bag storage case 1 so as to overlap in the X-axis direction. Each of the plurality of bags 7 has a pair of handles 74 located at both ends of the bag mouth 71 in the Y-axis direction, and a central portion of the bag mouth 71 in the Y-axis direction is separated by a cut line 702. 701 is connected. In the bag storage case 1 according to the present embodiment, the bag bundle 70 stored in such a state is sandwiched between the body 114 and the cover 115. Therefore, in each of the plurality of bags 7, for example, when air enters from the bag mouth 71, the side peripheral portion 73 is suppressed from spreading in the X-axis direction, and the size of the bag bundle 70 in the X-axis direction is expanded. It is suppressed.

  With the configuration as described above, the bag storage case 1 can store a plurality of bags 7 together. In addition, since the bag storage case 1 holds the bag bundle 70 having the plurality of bags 7 by the holding unit 12, the plurality of bags 7 are prevented from being separated in the bag storage case 1. Furthermore, the bag storage case 1 can take out the bags 7 one by one from the outlet 13 located on the opposite side of the holding portion 12 in the Z-axis direction with respect to the central portion 113 of the case body 11. That is, at least one bag 7 is exposed from the outlet 13 formed on the right side surface of the case body 11. Since the outlet 13 is located at the lower end of the case body 11, the end of the bag 7 on the bottom 72 side is exposed from the outlet 13. Therefore, in a state where one bag 7 exposed from the outlet 13 is captured by some means, the bag 7 is pulled downward (in the negative direction in the Z-axis direction) to release the holding at the holding portion 12. The single bag 7 can be taken out from the bag storage case 1 through the outlet 13.

  Here, the body 114 has a pair of flanges 16 that cover the region between the pair of handles 74 in the bag mouth 71 from above. The pair of flange portions 16 are divided into two in the Y-axis direction by the holding portion 12.

  Further, the cover 115 has a through-hole 17 penetrating in the X-axis direction at a position facing the bag bundle 70 in the X-axis direction in the closed position. In the present embodiment, three through holes 17 are formed in the cover 115. By providing the through hole 17, the frictional resistance between the cover 115 and the bag 7 is reduced as compared with the configuration without the through hole 17, and the bag 7 can be easily taken out from the bag storage case 1. Become.

  The case main body 11 further includes a pair of restricting protrusions 116 protruding in the Z-axis direction from both end surfaces (first end surface 111 and second end surface 112) in the Z-axis direction. Each of the pair of restricting protrusions 116 is formed long in the Y-axis direction. The pair of restricting protrusions 116 restricts the movement direction of the bag storage case 1 in the Y-axis direction when the bag storage case 1 is put in and out of the case storage space S2.

  The case body 11 further has a handle 117. The handle 117 protrudes from one end surface of the case body 11 in the Y-axis direction. The handle 117 is used, for example, when taking out the bag storage case 1 from the case storage space S2.

  Incidentally, as shown in FIG. 6, the case main body 11 further includes a pressing portion 18. The pressing part 18 presses the handle 74 of the plurality of bags 7 in the bag bundle 70 from at least one of the X-axis directions. 6 is a cross-sectional view taken along line YY of FIG. 5A. In the present embodiment, the pressing portion 18 protrudes from the surface of the cover 115 facing the body 114. Furthermore, a recess 118 is formed at a position facing the pressing portion 18 in the body 114. As a result, the handles 74 of the plurality of bags 7 in the bag bundle 70 are pushed by the pressing portion 18 and are pushed into the recess 118. As a result, the handles 74 of the plurality of bags 7 in the bag bundle 70 are prevented from sagging due to their own weight, and the handles 74 are unlikely to fall apart.

  The case body 11 further has a cushion material 19 on the surface of the body 114 facing the bag bundle 70. The cushion material 19 is made of, for example, a sheet-like elastic body such as synthetic rubber. The cushion material 19 facilitates the capture of the bag 7 by the capture unit 21 of the bag supply device 2 described later.

(2.3) Bag Supply Device Next, the bag supply device 2 will be described in more detail.

  The bag supply device 2 is a mechanism that supplies the bag 7 to the bagging device 3. In the following, one bag 7 in a state from when the bag supply device 2 is taken out from the bag storage case 1 and supplied to the bagging device 3 will be described as a target bag 700 (see FIG. 7A). The bag supply device 2 operates so as to cover the support bag 31 (see FIG. 10) and the guide unit 32 (see FIG. 10) in the bagging device 3 with the target bag 700 with the bag mouth 71 facing downward. To do. Details of the bagging device 3 will be described in the section “(2.4) Bagging device”.

  As shown in FIG. 1, the bag supply device 2 includes a take-out mechanism 20, a bag opening mechanism 5, and a set mechanism 6. FIG. 1 is a view of the counter table 8 as viewed from the rear (negative direction in the Y-axis direction). A part of the counter table 8 is broken, and a bag storage case 1 and a bag built in the counter table 8 are shown. It is the schematic which made the main part of the supply apparatus 2 and the bagging apparatus 3 visible. In FIG. 1, illustration of components that are not necessary for the following description is omitted as appropriate.

  The take-out mechanism 20 takes out one target bag 700 located at one end in the X-axis direction among the plurality of bags 7 from the bag bundle 70 having the plurality of bags 7. In the present embodiment, the bag supply device 2 takes out the target bag 700 from the bag bundle 70 stored in the bag storage case 1. Specifically, the bag supply is performed in the state in which the bag storage case 1 described in the column “(2.2) Bag storage case” is stored in the case storage space S2 formed in the frame 80 of the counter base 8. The device 2 takes out a single bag 7 to be the target bag 700 from the bag storage case 1. In this embodiment, since the bag 7 can be taken out from the take-out port 13 formed on the right side surface of the bag storage case 1 as described above, the take-out mechanism 20 has a case housing space so as to face the take-out port 13. It is arranged on the right side as viewed from S2. Thereby, the take-out mechanism 20 can take out one bag 7 positioned at the right end among the plurality of bags 7 as the target bag 700.

  Here, the take-out mechanism 20 includes a capturing unit 21 and a moving unit 22. The capturing unit 21 captures the target bag 700. The capturing unit 21 is, for example, a vacuum suction pad, and a surface facing the bag storage case 1 is a suction surface that sucks the target bag 700. The moving unit 22 moves the capturing unit 21. The moving unit 22 moves the capturing unit 21 relative to the frame 80 of the counter table 8 at least between the capturing position and the reverse position. The “capturing position” here is the position of the capturing portion 21 when facing the target bag 700 in the X-axis direction, and as illustrated in FIG. 7A, the capturing of the bag storage case 1 stored in the case storage space S2. This is the position facing the outlet 13. That is, in a state where the capture unit 21 is at the capture position, the capture unit 21 is located on the right side when viewed from the take-out port 13. Further, the “reverse position” here is a position where the direction of the capturing part in the Z-axis direction is reversed with respect to the capture position, as shown in FIG. 7B. Although described in detail later, the take-out mechanism 20 is also used as a reversing mechanism for reversing the direction of the target bag 700 in the Z-axis direction.

  The bag opening mechanism 5 is a mechanism that opens the target bag 700 so that the bag opening 71 of the target bag 700 taken out by the take-out mechanism 20 is widened. That is, in the state of the bag bundle 70, the plurality of bags 7 are stored in the bag storage case 1 so as to overlap in the X-axis direction with each bag mouth 71 closed. Therefore, the bag opening 71 is also closed for the target bag 700 taken out by the take-out mechanism 20. Therefore, the bag supply device 2 performs a process of widening the bag mouth 71 by the bag opening mechanism 5 on the target bag 700 to be supplied to the bagging device 3, that is, to cover the bagging device 3.

  In the present embodiment, the bag opening mechanism 5 includes a first suction pad 51 and a second suction pad 52. The first suction pad 51 and the second suction pad 52 are located on both sides in the X-axis direction of the side peripheral portion 73 of the target bag 700 in a state where the capturing unit 21 is in the reverse position. Each of the first suction pad 51 and the second suction pad 52 is, for example, a vacuum suction pad, and the surface facing the target bag 700 in a state where the capturing unit 21 is in the reverse position is the target bag 700 (side circumferential portion). 73). The bag opening mechanism 5 moves the first suction pad 51 and the second suction pad 52 in a state in which the side peripheral portion 73 of the target bag 700 is sucked from both sides in the X-axis direction, thereby moving the target bag 700 away from each other. Spread the bag mouth 71.

  The set mechanism 6 puts the target bag 700 taken out by the take-out mechanism 20 on the guide unit 32 from above with the bag mouth 71 of the target bag 700 facing downward, so that the target bag 700 is placed against the bagging device 3. Is a mechanism for setting (preparing). Here, the setting mechanism 6 sets the target bag 700 by covering the target bag 700 opened by the bag opening mechanism 5 with respect to the support portion 31 and the guide portion 32 from above.

  In the present embodiment, the set mechanism 6 includes a preliminary opening part 61 and a second lifting part 62. The second elevating part 62 moves the guide part 32 in the Z-axis direction relative to the frame 80 of the counter table 8. That is, the guide part 32 located below the target bag 700 in the state where the bag opening 71 is opened at the preliminary opening part 61 is raised by the second elevating part 62 so that the guide part 32 is moved from the bag opening 71 of the target bag 700. Is inserted. The preliminary opening portion 61 is provided between the guide portion 32 and the bag mouth 71 of the target bag 700, and before the guide portion 32 is inserted into the bag mouth 71 of the target bag 700 from below, Open mouth 71. The preliminary opening portion 61 widens the bag mouth 71 of the target bag 700 so that at least the guide portion 32 can be inserted.

  Hereinafter, operation | movement of the bag supply apparatus 2 is demonstrated with reference to FIG. 7A-FIG. 8B. 7A to 8B schematically show the operation of the bag supply device 2, and illustration of the first elevating part 33 and the like is omitted as appropriate. Moreover, in FIG. 7A-FIG. 8B, the state of each part after a movement is shown with the imaginary line (two-dot chain line).

  First, as shown in FIG. 7A, the take-out mechanism 20 has a right end (one end in the X-axis direction) among the plurality of bags 7 stored in the bag storage case 1 in a state where the capture unit 21 is in the capture position. The single bag 7 located at is captured. Specifically, the capture unit 21 is exposed at the bottom 72 side end of the target bag 700 from the outlet 13 disposed at the lower end of the bag storage case 1. The target bag 700 is captured by adsorbing the end on the bottom 72 side from the right side. When the capturing unit 21 captures (sucks) the target bag 700, the moving unit 22 further pushes the capturing unit 21 further toward the target bag 700 from the position where the capturing unit 21 contacts the target bag 700, thereby capturing the capturing unit 21. Improves the certainty of adsorption.

  Then, the take-out mechanism 20 catches in the negative direction (downward) in the Z-axis direction that intersects (here, orthogonal) in the X-axis direction in a state where the target bag 700 is captured by the capture unit 21 arranged at the capture position. The target bag 700 is taken out from the bag bundle 70 by moving the unit 21 by the moving unit 22. At this time, in the bag storage case 1, the end portion on the bottom 72 side of the target bag 700 is pulled downward, and the target bag 700 is separated from the separation portion 701 by the cut line 702, whereby the target by the holding unit 12. The holding of the bag 700 is released. Thereby, the target bag 700 can be taken out from the outlet 13. That is, the take-out mechanism 20 moves the catcher 21 in a state where the single bag 7 (target bag 700) exposed from the take-out port 13 of the bag storage case 1 is captured in the Z-axis direction by the moving unit 22. Thus, the target bag 700 can be pulled out from the outlet 13.

  Here, when the capture unit 21 captures (adsorbs) the target bag 700, the capture unit 21 captures (adsorbs) the bonding portion 75 (see FIG. 4) located at the end portion on the bottom 72 side of the target bag 700. ) Is preferable. That is, each of the plurality of bags 7 has a bonding portion 75 in which a pair of sheets (a sheet forming the right side surface and a sheet forming the left side surface) are bonded together by heat welding or the like. The capturing unit 21 captures the bonding unit 75, so that when the moving unit 22 moves the capturing unit 21 in the Z-axis direction, the capturing unit 21 can evenly pull a pair of sheets constituting the target bag 700. 12, the holding of the target bag 700 by 12 is easily released. For the same reason, when the capturing unit 21 captures (adsorbs) the target bag 700, it is preferable that the capturing unit 21 captures a portion of the target bag 700 that is as close as possible to the bottom 72. That is, the closer the portion captured by the capture unit 21 is to the bottom portion 72 of the target bag 700, the more the pulling of the pair of sheets constituting the target bag 700 is performed when the moving unit 22 moves the capture unit 21 in the Z-axis direction. And the holding of the target bag 700 by the holding unit 12 is easily released.

  Here, the take-out mechanism 20 moves the capturing unit 21 in a state where the target bag 700 is captured to the inversion position by the moving unit 22. Accordingly, the take-out mechanism 20 can reverse the direction of the target bag 700 in the Z-axis direction from the state included in the bag bundle 70 with respect to the target bag 700 taken out from the bag storage case 1. That is, the moving unit 22 is not only pulled out of the bag storage case 1 by moving the capturing unit 21 in the Z-axis direction, but is further captured by the capturing unit 21 by moving the capturing unit 21. The direction of the target bag 700 is reversed. Thereby, the take-out mechanism 20 is also used as a reversing mechanism.

  In the state where the capture unit 21 has moved to the reverse position, as illustrated in FIG. 7B, the capture unit 21 sucks the end portion on the bottom 72 side of the target bag 700 to move the bag mouth 71 downward (in the Z-axis direction). The target bag 700 is held in an upside-down posture toward the negative direction. In this state, the moving unit 22 moves the capturing unit 21 straight to the right (positive direction in the X-axis direction).

  Thereafter, as shown in FIG. 7C, the bag opening mechanism 5 moves the second suction pad 52 located on the right side of the target bag 700 to the left (negative direction in the X-axis direction), and moves the target bag. The target bag 700 is sandwiched between the first suction pad 51 and the second suction pad 52 located on the left side of the 700. In this state, the bag opening mechanism 5 uses the first suction pad 51 and the second suction pad 52 to suck the side peripheral portion 73 of the target bag 700 from both sides in the X-axis direction. At this time, the suction of the target bag 700 by the capturing unit 21 is released, and the target bag 700 is released from the capturing unit 21. The bag opening mechanism 5 moves the second suction pad 52 straight to the right (positive direction in the X-axis direction) while sucking the target bag 700 with the first suction pad 51 and the second suction pad 52. The bag mouth 71 of the target bag 700 is expanded in the X-axis direction. Accordingly, the target bag 700 is pulled from both sides in the X-axis direction by the first suction pad 51 and the second suction pad 52, and is held in a state where the bag mouth 71 is open.

  Thereafter, as shown in FIG. 8A, the setting mechanism 6 moves the bagging device 3 (guide portion 32) located below the target bag 700 upward at the second lifting / lowering portion 62 (positive direction in the Z-axis direction). Move to. The details will be described in the section of “(2.4) Bagging device”. When the bag 7 is supplied to the bagging device 3 by the bag supply device 2, the guide unit 32 is raised by the second lifting / lowering unit 62. The first elevating part 33 of the bagging device 3 raises the support part 31. Thereby, when the bag 7 is supplied to the bagging device 3 by the bag supply device 2, both the support portion 31 and the guide portion 32 rise relative to the frame 80 of the counter base 8.

  At this time, prior to the guide portion 32 being inserted into the bag mouth 71 of the target bag 700 from below, the preliminary opening portion 61 widens the bag mouth 71 of the target bag 700. The preliminary opening portion 61 operates so as to widen the four corners (four corners in the XY plane) of the bag mouth 71 from the inside of the bag mouth 71, so that the guide portion 32 is moved with respect to the bag mouth 71 of the target bag 700. Secure the size that can be inserted. In this state, when the bagging device 3 (the support portion 31 and the guide portion 32) is raised to a predetermined position, as shown in FIG. 8B, the target bag 700 with the bag mouth 71 facing downward is placed in the bagging device 3. Can be covered from above. Thereby, the bag supply device 2 completes the supply of the target bag 700 to the bagging device 3.

  Hereinafter, a specific configuration of the bag supply device 2 will be described with reference to FIGS. 9 and 10.

  As shown in FIG. 9, the bag supply device 2 includes a capturing unit 21 and a moving unit 22 that moves the capturing unit 21 relative to the frame 80 of the counter base 8. The capturing unit 21 and the moving unit 22 constitute the take-out mechanism 20 as described above.

  In the example of FIG. 9, the capture unit 21 is configured to be movable in both directions between a capture position and a reverse position by a belt-driven moving unit 22. That is, the moving unit 22 includes a movable frame 221, a pair of pulleys 222, a pair of belts 223, a first motor 224, a pair of slide rails 225, and a second motor 226.

  The movable frame 221 is a frame-shaped member that is open on both sides in the X-axis direction, and is configured to be movable in the X-axis direction by a pair of slide rails 225 and a second motor 226. The pair of pulleys 222 are disposed at both ends of the movable frame 221 in the Z-axis direction. Each of the pair of pulleys 222 is configured to be rotatable about the Y axis as a rotation axis. The pair of belts 223 are disposed at both ends of the movable frame 221 in the Y-axis direction. Each of the pair of belts 223 is spanned between the pair of pulleys 222. The first motor 224 drives the pair of belts 223 by applying a driving force (rotational force) to one of the pair of pulleys 222 (upper side in the present embodiment). The pair of slide rails 225 is fixed to the frame 80 of the counter base 8 and restricts the moving direction of the movable frame 221 in the X-axis direction. The second motor 226 is a linear motion motor, and drives the movable frame 221 by applying a driving force along the X-axis direction to the movable frame 221.

  The capturing unit 21 is attached so as to be bridged between the pair of belts 223. Therefore, when the first motor 224 drives the pair of belts 223, the capturing unit 21 moves on an elliptical path that is long in the Z-axis direction and is formed on the outer periphery of the pair of belts 223. Here, the suction surface of the capturing unit 21 is directed to the side opposite to the pair of belts 223. Accordingly, when the first motor 224 drives the pair of belts 223 in a state where the capturing unit 21 captures the target bag 700, the target bag 700 has a long length in the Z-axis direction formed on the outer periphery of the pair of belts 223. Move on a circular path. In addition, when the second motor 226 drives the movable frame 221, the capturing unit 21 moves straight in the X-axis direction. With the above configuration, movement of the capturing unit 21 by the moving unit 22 as illustrated in FIGS. 7A to 7C is realized.

  Further, the first suction pad 51 in the bag opening mechanism 5 is fixed to the movable frame 221. Here, the suction surface of the first suction pad 51 is directed to the opposite side (right side) of the case housing space S <b> 2 and is exposed from between the pair of belts 223. A plurality of suction ports 511 are arranged on the suction surface of the first suction pad 51. Thereby, the moving part 22 moves the movable frame 221 in the X-axis direction, so that the first suction pad 51 moves in the X-axis direction together with the movable frame 221. With the above configuration, movement of the first suction pad 51 as shown in FIGS. 7A to 7C is realized.

  In the present embodiment, each of the capturing unit 21 and the first suction pad 51 is composed of a vacuum suction pad, and is thus connected to the vacuum pump by the hose 23. The vacuum pump is housed, for example, on the left side of the case housing space S2 in the counter base 8. In addition, a hose guide 24 that prevents the hose 23 from being caught between the belt 223 and the pulley 222 is attached to one belt 223.

  In addition, as shown in FIG. 10, the bag supply device 2 further includes a set mechanism 6 that includes a preliminary opening portion 61, a second elevating portion 62, and a link 63. That is, in the present embodiment, the set mechanism 6 includes a preliminary opening portion 61, a second lifting / lowering portion 62, and a link 63.

  The second elevating unit 62 includes a second support column 621 and a second arm 622. The second column 621 is a column that is long in the vertical direction, and is fixed to the frame 80 of the counter table 8. The second arm 622 is movable along the longitudinal direction (vertical direction) of the second support column 621. One end portion of the second arm 622 is mechanically coupled to the side surface of the guide portion 32. The 2nd raising / lowering part 62 raises / lowers the guide part 32 by moving the 2nd arm 622 to an up-down direction (lifting / lowering). The second elevating unit 62 includes an electric motor (motor), and is realized by an appropriate mechanism that can move the second arm 622 straight up and down by a driving force generated by the electric motor, such as a pantograph type or a rack and pinion type. The

  The preliminary opening 61 is composed of a plurality of (here, four) flaps 611. The plurality of flaps 611 are arranged separately on both sides in the Y-axis direction with respect to the guide portion 32. In the present embodiment, a pair of flaps 611 is located in front of the guide portion 32, and a pair of flaps 611 is also located behind the guide portion 32. Each of the plurality of flaps 611 is configured to be rotatable around a rotation axis 612 along the X-axis direction. The plurality of rotating shafts 612 are supported by a plurality of fixtures 64. The plurality of fixtures 64 are fixed to the frame 80 of the counter base 8. Each of the plurality of flaps 611 rotates and moves between a “standby position” (state shown in FIG. 10) along the horizontal direction and an “operating position” (state shown in FIG. 8B) along the vertical direction.

  The link 63 is a mechanism that opens and closes (rotates) the plurality of flaps 611 in conjunction with the second elevating unit 62. That is, when the second elevating part 62 raises the guide part 32, the plurality of flaps 611 are rotated via the link 63 so as to be flipped up from the standby position and moved to the operating position. At this time, the preliminary opening portion 61 widens the four corners (four corners in the XY plane) of the bag mouth 71 from the inside of the bag mouth 71 with a plurality of flaps 611 in the operating position. With the above configuration, the preliminary opening portion 61 operates so as to open the target bag 700 from the inside of the bag mouth 71 with the plurality of flaps 611 as the guide portion 32 moves upward, as shown in FIGS. 8A to 8B. Such an operation of the preliminary opening portion 61 is realized. It is preferable that the outer peripheral shape (the inner peripheral shape of the bag mouth 71) formed by the plurality of flaps 611 in the operating position is similar to the outer peripheral shape of the guide portion 32. When the bag filling is completed and the guide portion 32 is lowered, the plurality of flaps 611 are moved to the standby position.

(2.4) Bagging Device Next, the bagging device 3 will be described in more detail.

  As shown in FIG. 10, the bagging device 3 according to the present embodiment includes a support portion 31, a guide portion 32, and a first elevating portion 33.

  The support part 31 is formed in a rectangular plate shape. The upper surface of the support portion 31 constitutes a placement surface 311 on which the product 91 is placed. Here, the mounting surface 311 has a rectangular shape with rounded corners.

  The guide part 32 is formed in a cylindrical shape having at least an upper surface opened between the upper surface and the lower surface. In this embodiment, the guide part 32 is formed in the square cylinder shape which both the upper surface and the lower surface opened. The opening surface of the guide portion 32 is formed to be slightly larger than the placement surface 311, and the guide portion 32 is disposed around the support portion 31 along the outer peripheral edge of the placement surface 311. Here, the shape of the inner peripheral edge of the upper end surface of the guide portion 32 and the shape of the outer peripheral edge of the placement surface 311 are similar.

  The 1st raising / lowering part 33 changes the relative positional relationship of the support part 31 and the guide part 32 from a 1st state to a 2nd state. Here, the state in which the support portion 31 is located at the upper end portion of the guide portion 32 is referred to as a first state. When the relative positional relationship between the support portion 31 and the guide portion 32 is in the first state, the upper surface (mounting surface 311) of the support portion 31 and the upper end surface of the guide portion 32 are substantially flush with each other. Therefore, in the first state, the support portion 31 is disposed so as to close the opening on the upper surface side of the guide portion 32. The second state is a state in which the relative position of the support portion 31 with respect to the guide portion 32 is lower than the first state.

  In other words, the support part 31 moves relative to the guide part 32 in a space surrounded by the guide part 32. In the present embodiment, the first elevating unit 33 moves only the support unit 31 out of the support unit 31 and the guide unit 32 downward, thereby determining the relative positional relationship between the support unit 31 and the guide unit 32. The state is changed from the first state to the second state. That is, the support part 31 is configured to move in the vertical direction by the first elevating part 33 in the cylindrical guide part 32 fixed at a fixed position.

  More specifically, the first elevating unit 33 includes a first support column 331 and a first arm 332. The first support column 331 is a support column that is long in the vertical direction, and is fixed to the frame 80 of the counter base 8. The first arm 332 is movable along the longitudinal direction (vertical direction) of the first support column 331. The first arm 332 is inserted into the guide portion 32 through a slit formed in the side surface of the guide portion 32, and one end portion of the first arm 332 is mechanically connected to the lower surface of the support portion 31 inside the guide portion 32. Are combined. The 1st raising / lowering part 33 raises / lowers the support part 31 by moving the 1st arm 332 to an up-down direction (lifting / lowering). The first elevating unit 33 includes an electric motor (motor), and is realized by an appropriate mechanism such as a pantograph type or a rack and pinion type that can move the first arm 332 straight up and down by a driving force generated by the electric motor. The

  Hereinafter, operation | movement of the bagging apparatus 3 is demonstrated with reference to FIG. 11A-FIG. 12B. In FIG. 11A-FIG. 12B, operation | movement of the bag filling apparatus 3 is represented typically, and illustration of the bag supply apparatus 2, the 1st raising / lowering part 33, etc. is abbreviate | omitted suitably.

  11A to 11C show a process in which the product 91 is accommodated in the bag 7 when the relative positional relationship between the support portion 31 and the guide portion 32 changes from the first state to the second state. In the figure, a plurality of products 91 such as a plastic bottle beverage, a boxed confectionery, and a can juice are illustrated, but one product 91 may be provided. In addition, as an example here, the shopping basket 92 is removed from the bagging device 3 in the process of FIG. 11B, but the timing at which the shopping basket 92 is removed may be the process of FIG. 11C. It may be after that.

  First, when the relative positional relationship between the support portion 31 and the guide portion 32 is in the first state, as shown in FIG. 11A, the bag 7 with the bag mouth 71 facing down covers the support portion 31 and the guide portion 32. The bottom portion 72 of the bag 7 is supported by the placement surface 311. The bagging apparatus 3 sets the state shown in FIG. 11A to the standby state, and waits in the standby state until the shopping basket 92 containing the product 91 is placed in the bagging space (in the recess 82) on the placement surface 311. . In the present embodiment, when the shopping basket 92 is placed in the bagging space (in the recess 82), first, the shutter 821 constituting the bottom surface of the recess 82 is opened. Then, the product 91 in the shopping basket 92 is discharged onto the placement surface 311 of the bagging device 3 by opening the bottom of the shopping basket 92. As a result, the product 91 is placed on the placement surface 311 through the bag 7. At this time, the bottom 72 is held on the placement surface 311 by the holding force of the holding mechanism 34 described later in addition to the weight of the product 91.

  From this state (first state), the support part 31 moves relatively downward with respect to the guide part 32 in the first elevating part 33, whereby the bag 7 is guided to the guide part 32 as shown in FIG. Gradually pulled inside. At this time, the side peripheral portion 73 of the bag 7 continuing to the bottom portion 72 of the bag 7 is drawn into the guide portion 32 while being squeezed by the upper end surface of the guide portion 32. Therefore, the side peripheral portion 73 of the bag 7 is raised upward from the outer peripheral edge of the bottom portion 72 by the guide portion 32 around the support portion 31.

  And when the relative positional relationship of the support part 31 and the guide part 32 will be in a 2nd state, as shown to FIG. 11C, in the space enclosed by the guide part 32, the bag 7 turned over from the state of FIG. 11A. The product 91 is accommodated in the bag 7. At this time, the side peripheral portion 73 rises along the inner peripheral surface of the guide portion 32. Here, in the second state, the bagging device 3 is configured such that the height difference from the placement surface 311 to the upper end surface of the guide portion 32 is equal to or greater than the total length of the bag 7 in the vertical direction. The “total length of the bag 7 in the vertical direction” here is the total length including the pair of handles 74 of the bag 7, that is, the dimension from the bottom 72 of the bag 7 to the tip of the handle 74. As a result, the bag 7 fits in the space surrounded by the guide portion 32 up to the tip of the handle 74. Therefore, the bag 7 is in a state of standing up including not only the side peripheral portion 73 but also the handle 74.

  Next, the bagging device 3 drives the support part 31 by the first lifting part 33 and changes the relative positional relationship between the support part 31 and the guide part 32 from the second state to the first state. Thus, the bag 7 is discharged from the space surrounded by the guide portion 32.

  That is, as shown in FIG. 12A, the bag 7 on the placement surface 311 protrudes upward from the opening on the upper surface side of the guide portion 32 as the support portion 31 moves upward. Furthermore, as the support portion 31 moves upward, the bag 7 is completely discharged from the space surrounded by the guide portion 32 as shown in FIG. 12B. At this time, the bag 7 maintains an independent posture including the handle 74. Moreover, since the bag 7 is turned over from the state of FIG. 11A supplied with the bag supply apparatus 2 and accommodates the product 91, when the character or the like is printed on the bag 7, the reversely printed bag 7 is used. It is preferable.

  By the operation as described above, the bagging device 3 stores the product 91 placed in the bagging space on the placement surface 311 in the bag 7 and raises the handle 74 of the bag 7 in the state where the product 91 is raised. Can be delivered to the customer. When the product 91 disappears from the placement surface 311, the bagging device 3 newly sets the bag 7 and stands by in a standby state.

  By the way, in this embodiment, in addition to the support part 31, the guide part 32, and the 1st raising / lowering part 33, the bagging apparatus 3 has the holding mechanism 34 as shown to FIG. 13A-FIG. 13C.

  The holding mechanism 34 is a mechanism that holds the bottom portion 72 of the bag 7 on the placement surface 311. The holding mechanism 34 is configured to be switchable between a state in which the bottom 72 is held on the placement surface 311 and a state in which the holding is released. Here, “holding” means that the mounting surface 311 keeps supporting the bottom 72. That is, the holding mechanism 34 maintains the state in which the bottom portion 72 is in contact with the placement surface 311 and supported by the placement surface 311 from below. The bagging device 3 is configured so that the bottom portion 72 of the bag 7 is placed on the mounting surface 311 by the holding mechanism 34 while at least the relative positional relationship between the support portion 31 and the guide portion 32 changes from the first state to the second state. Keep holding.

  In the present embodiment, the holding mechanism 34 holds the bottom 72 by pinching the bottom 72 of the bag 7. Specifically, a pair of holding grooves 312 (see FIG. 10) along the X direction are formed at both ends in the Y direction on the upper surface (mounting surface 311) of the support portion 31. The holding mechanism 34 is provided in each of the pair of holding grooves 312, and holds the bottom portion 72 in the holding groove 312 by sandwiching the bottom portion 72 pushed into the holding groove 312. As shown in FIGS. 13A and 13B, the bottom 72 is pushed into the holding groove 312 by fins 822 that protrude downward from the lower surface of the shutter 821 that forms the bottom surface of the recess 82. The holding mechanism 34 includes a rotating shaft 341 and a pressing spring 342 formed of a leaf spring. By rotating the rotating shaft 341, the holding mechanism 34 moves the pressing spring 342 into the holding groove 312 and the holding groove 312. It moves between the retracted position retracted from.

  That is, when the bag 7 is supplied to the bagging device 3 by the bag supply device 2, the support portion 31 and the guide portion 32 are raised relative to the shutter 821 as shown in FIG. 13A. At this time, as shown in FIG. 13B, the bagging device 3 enters a standby state and waits with the support portion 31 and the guide portion 32 raised to the position where the fins 822 are inserted into the holding grooves 312. Thereby, a part of the bottom 72 is pushed into the holding groove 312 by the fins 822. In this state, the pressing spring 342 is in the retracted position. In this state, when the shopping basket 92 is placed in the bagging space (in the recess 82) and the shutter 821 is opened, a part of the bottom 72 is left in the holding groove 312 and the bagging device 3 is moved upward. Thus, the shutter 821 and the fins 822 are removed. At this time, as shown in FIG. 13C, the holding mechanism 34 rotates the rotating shaft 341 and moves the pressing spring 342 from the retracted position to the entering position. As a result, a part of the bottom 72 is pressed against the side surface of the holding groove 312 by the pressing spring 342 in the holding groove 312, and the holding mechanism 34 can grip the bottom 72 of the bag 7.

(4) Modifications The above embodiment is merely an example of the present invention, and the present invention is not limited to the above embodiment, and deviates from the technical idea according to the present invention even if it is other than the above embodiment. Various changes can be made in accordance with the design or the like as long as they are not.

  Hereinafter, modifications of the embodiment will be listed.

  The bagging device 3 is capable of bagging not only the product 91 in the shopping basket 92 but also the product 91 that is not in the shopping basket 92. In this case, the customer can cause the bagging apparatus 3 to pack the product 91 by placing the product 91 directly in the bagging space.

  The use of the bagging device 3 is not limited to the convenience store, and the bagging device 3 may be installed in a store other than the convenience store. Furthermore, for example, the bagging device 3 may be installed in a facility other than a store, such as an office or a factory.

  Moreover, the bagging apparatus 3 should just be the structure which accommodates the goods 91 in the bag 7, and accommodates the goods 91 in bags 7, such as not only a shopping bag as mentioned above but an eco bag, a net bag, etc. (bag) It may be configured to be stuffed). The material of the shopping bag is not limited to polyethylene but may be made of polypropylene, for example.

  Further, the shopping support system 100 may not be used in conjunction with the sales system 4 that can purchase the product 91 without requiring the operation of a store clerk as in the above-described embodiment. For example, like the so-called manned cash register It may be used in a situation where there is a store clerk at the checkout counter.

  Further, for example, the fact that the bagging device 3 and the sales system 4 are integrated in one housing (counter stand 8) is not an essential configuration for the shopping support system 100, and there are a plurality of components of the shopping support system 100. It may be provided in a distributed manner in the casing.

  Further, the bag supply device 2 may be configured to supply the bag filling device 3 after turning the bag 7 upside down. In this case, since the bag 7 is set in the bagging device 3 in an inverted state and further turned over to accommodate the product 91, the outer surface of the original bag 7 becomes the outer surface in the state in which the product 91 is accommodated. . Therefore, when characters or the like are printed on the bag 7, it is not necessary to use the reverse-printed bag 7.

  The bag storage case 1 preferably has a sensor for counting the remaining number of bags 7. In this case, if the remaining number of bags 7 in the bag storage case 1 is equal to or less than a set value (for example, 5 sheets), a notification that prompts the store clerk to replenish the bags 7 may be performed by the notification unit. preferable.

  In addition, the holding mechanism 34 of the bagging device 3 is not limited to the configuration in which the bottom portion 72 is held by picking the bottom portion 72 of the bag 7 as in the above-described embodiment.

That is, the take-out mechanism 20 may move the capturing unit 21 in the second direction intersecting the first direction that is the thickness direction of each of the plurality of bags 7 by the moving unit 22, for example, in the second direction. May be diagonally downward. At this time, the inclination angle of the second direction with respect to the vertical direction is preferably 30 degrees or less. The inclination angle in the second direction with respect to the vertical direction is more preferably 5 degrees or less. The smaller the inclination angle in the second direction with respect to the vertical direction, the easier it is for the bag 7 to be separated from the separating portion 701 at the cut line 702.

  The capturing unit 21 is not limited to the suction pad, and may capture the target bag 700 by, for example, a configuration in which the side peripheral portion 73 of the target bag 700 is picked.

  Moreover, in the structure which the capture part 21 captures the bonding part 75 (refer FIG. 4) located in the edge part by the side of the bottom part 72 among the object bags 700, the dimension of the bonding part 75 in a Z-axis direction is comparatively comparative. It is preferable to ensure a large value. Thereby, it becomes easy to capture (adsorb) the bonding part 75 in the capturing part 21, and the certainty of capturing the bag 7 by the capturing part 21 is improved.

  Moreover, the bag opening mechanism 5 is not limited to the configuration having two suction pads (the first suction pad 51 and the second suction pad 52), and may have three or more suction pads. Further, the bag opening mechanism 5 is not limited to the suction pad, and the target bag 700 may be configured to grip the side peripheral portion 73 of the target bag 700 or to send air to the target bag 700 from the bag port 71. You may open it.

  Further, the bag storage case 1 is not limited to the mode used in combination with the bag supply device 2, and may be used such that a person takes out the bag 7 by hand. The bag supply device 2 is not limited to the mode used in combination with the bag storage case 1, and for example, may be configured to take out the target bag 700 from the bag bundle 70 that is not stored in the bag storage case 1. Good.

  Further, when a plurality of types of bags 7 having different sizes or colors are used, different types of bags 7 may be stored for each bag storage case 1. In this case, it is preferable that the bag supply device 2 is configured to select one bag storage case 1 from the plurality of bag storage cases 1 at any time and take out the target bag 700 from the selected bag storage case 1.

  Further, the pressing portion 18 that holds the handles 74 of the plurality of bags 7 in the bag bundle 70 is not limited to the above-described configuration, and may be configured by, for example, an elastic roller. In this case, the handle 74 is released from the pressing portion 18 by rotating the roller.

  Further, the moving unit 22 is not limited to the belt drive type, and the capture unit 21 may be moved by a configuration such as a chain drive type or a robot arm, for example.

  In the above embodiment, the bag supply device 2 opens the target bag 700 with the bag opening mechanism 5 after reversing the direction of the target bag 700 in the Z-axis direction with the reversing mechanism. Not exclusively. That is, the bag supply device 2 may reverse the direction of the target bag 700 in the Z-axis direction by the reversing mechanism after opening the target bag 700 by the bag opening mechanism 5.

  The various modifications described above can be applied in appropriate combination.

(5) Summary As described above, the bag storage case (1) according to the first aspect of the present invention includes the case main body (11) for storing the bag bundle (70) and the bag in the case main body (11). A holding part (12) for holding the bundle (70). The bag bundle (70) has a plurality of bags (7) in a state of being overlapped with each other in the first direction which is the thickness direction. The case body (11) includes a central portion (113), a first end surface (111) and a second end surface (112), and an outlet (13) for taking out each of the plurality of bags (7). Have. The central portion (113) is located at the center of the second direction intersecting the first direction. The first end surface (111) and the second end surface (112) are located at both ends in the second direction. The outlet (13) opens at a position between the central portion (113) and the first end surface (111) in the second direction. The holding part (12) is located between the center part (113) and the second end face (112) in the second direction of the case body (11).

  According to this configuration, the bag storage case (1) can store a plurality of bags (7) together in a bag bundle (70). Moreover, since the bag storage case (1) holds the bag bundle (70) having a plurality of bags (7) by the holding portion (12), a plurality of bags (7) are stored in the bag storage case (1). ) Is suppressed. Further, the bag storage case (1) has a bag (7) from an outlet (13) located on the opposite side of the holding portion (12) in the Z-axis direction with respect to the center portion (113) of the case body (11). Can be taken out one by one. Therefore, the holding of the holding portion (12) is released by pulling the bag (7) in the second direction while the bag (7) exposed from the outlet (13) is captured by some means. It is possible to take out one bag (7) from the bag storage case (1). Therefore, even if a sufficient space cannot be secured on the side in the first direction with respect to the bag bundle (70), it is possible to take out one bag (7) from the bag storage case (1). Therefore, there exists an advantage that the effort concerning handling of a bag (7) can be reduced.

  In the bag storage case (1) according to the second aspect of the present invention, in the first aspect, the outlet (13) is preferably formed on one surface of the case body (11) in the first direction.

  According to this configuration, by pulling one bag (7) exposed from the outlet (13) formed on one surface of the case body (11) in the first direction in the second direction, the outlet (13) It is possible to take out one bag (7) from the bag storage case (1). Therefore, it becomes easy to set the exposed area of the bag (7) from the take-out port (13) to a size larger than that for capturing the bag (7). However, this configuration is not essential for the bag storage case (1). For example, the outlet (13) may be formed on one surface of the case body (11) in the second direction.

  In the bag storage case (1) according to the third aspect of the present invention, in the first or second aspect, the bag bundle (70) is detachably connected to the plurality of bags (7).

  According to this configuration, the bag supply device (2) can take out one target bag (700) from the plurality of bags (7) in the bag bundle (70) state. Moreover, since the bag supply device (2) takes out one target bag (700) located at one end in the first direction among the plurality of bags (7), a plurality of bag supply devices (2) can be used when taking out the target bag (700). It is suppressed that the bag (7) of sheets separates. Further, the take-out mechanism (20) moves the catching part (21) in the second direction by the moving part (22) in the state where the target bag (700) is caught by the catching part (21). The target bag (700) can be removed from the bundle (70). Therefore, even when a sufficient space cannot be secured laterally in the first direction with respect to the bag bundle (70), the target bag (700) can be taken out from the bag bundle (70). Therefore, there exists an advantage that the effort concerning handling of a bag (7) can be reduced.

  The bag supply device (2) according to an eighth aspect of the present invention is the bag supply device (700) according to the seventh aspect, so that the bag mouth (71) of the target bag (700) taken out by the take-out mechanism (20) is widened. It is preferable to further include a bag opening mechanism (5).

  According to this configuration, for example, when the target bag (700) is supplied to the bagging device (3), the operation of opening the target bag (700) can be automated. However, this configuration is not essential for the bag supply device (2), and the bag opening mechanism (5) can be omitted as appropriate.

  The bag supply device (2) according to the ninth aspect of the present invention preferably further comprises a reversing mechanism in the seventh or eighth aspect. The reversing mechanism reverses the direction of the target bag (700) in the second direction from the state included in the bag bundle (70) for the target bag (700) taken out by the take-out mechanism (20).

  According to this configuration, for example, when supplying the target bag (700) to the bagging device (3), the work of reversing the direction of the target bag (700) in the second direction can be automated. However, this configuration is not essential for the bag supply device (2), and the reversing mechanism can be omitted as appropriate.

  The bag supply device (2) according to the tenth aspect of the present invention is the bag supply device (2) according to the ninth aspect, wherein the take-out mechanism (20) is configured so that the direction of the capturing part (21) in the second direction is reversed. It is preferable to also serve as a reversing mechanism by moving the capturing part (21) according to 22).

  According to this configuration, the configuration of the bag supply device (2) can be simplified compared to the case where a reversing mechanism is provided separately from the take-out mechanism (20). However, this configuration is not essential for the bag supply device (2), and the reversing mechanism may be provided separately from the take-out mechanism (20).

  The bag supply device (2) according to the eleventh aspect of the present invention preferably further comprises a set mechanism (6) in any of the seventh to tenth aspects. The set mechanism (6) guides the target bag (700) taken out by the take-out mechanism (20) to the bagging device (3) with the bag mouth (71) of the target bag (700) facing downward.
