  As shown in FIG. 16, a transport endless body 51 such as a chain is hung up and down across a transport rotating wheel body 52 (only the upper transport rotating wheel body is shown) such as a pair of upper and lower sprockets. The product 54 is placed on the product shelf 53 attached to the transport endless body 51, and the product shelf 53 on which the product 54 is placed is lowered to the lower end position of the transport endless body 52 and downward. A product storage / conveyance device for a vending machine configured such that the product 54 is dropped and carried out from the product shelf 53 by being rotated in a facing posture is already known as disclosed in, for example, Patent Document 1 and the like. Yes. Note that reference numeral 60 in FIG. 16 denotes a drive motor that rotates the upper transport rotary wheel 52 and thereby moves the transport endless body 51 and the product shelf 53.

  In this type of product storage and transport apparatus, as shown in FIGS. 16 and 17, a storage column 50, which is a space in which the product storage and transport apparatus is disposed, includes an outer frame (rack case) 55 and a column partition plate. 56 and the like, and is partitioned into a substantially rectangular shape in plan view. In the storage column 50, a storage transport path (storage transport area) 58 for storing and transporting the products 54, a transport endless body 52, a product shelf 53 on which the products 54 cannot be placed, and the like are disposed. Thus, a non-storage area 57 in which the product 54 is not stored is provided. Here, a product replenishment opening 59 for replenishing the product 54 is provided on one side of the storage column 50 facing the storage transport passage 58, but a transport endless body 52 and the like are disposed. The non-storage area 57 is disposed at a location facing the product replenishment opening 59 in the storage column 50.

Japanese Patent Laid-Open No. 9-50574

  However, according to the product storage / conveyance device of the vending machine having the conventional structure, in the storage column 50, the non-storage region 57 in which the transport endless body 52 and the like are disposed faces the product replenishment opening 59. 17, as shown in FIG. 17, the dimension L2 is smaller than the depth L0 of the storage column 50 by a dimension L2 smaller than the dimension L1 of the non-storage area 57 in which the transporting endless body 52 and the like are disposed. Only the product 54 can be stored in principle. Accordingly, the storage column 50 is sold when the width (depth dimension L0) of the storage column 50 is limited, such as when the structure of the product storage and transport device is to be adopted in a storage column that has been widely used conventionally. This causes the problem that the products 54 to be processed are considerably limited.

  Further, when using the product storage and transport device of the vending machine having the conventional structure, if the product 54 has a size that is slightly larger than the dimension L2, the product 54 is placed on the product shelf 53 and then dropped off. It is conceivable to store the product 54 so that the end of the product 54 is brought into contact with the drop-off prevention door 61, but in this case, when the drop-off prevention door 61 is opened, The posture may change, and the product 54 may come out of the product supplement opening 59 and fall off.

  Moreover, since the collar part 53a formed in the edge part of the goods shelf 53 is the structure which latches to the pin 51a of the endless body 51 for conveyance, the attachment position of the goods shelf 53 is changed according to the change of goods 54, etc. In such a case, there is a high possibility that a large number of pins 51a are erroneously attached to the pin 51a adjacent to the appropriate pin 51a. For this reason, there is a problem that it takes much time and time to confirm the pin 51a to be attached.

  Furthermore, when the product 54 to be sold is changed from a large one to a small one and it is desired to increase the number of items to be stored, it is necessary to reattach the product shelf 53, and this requires a lot of labor and time. .

  The present invention solves the above-mentioned problems and difficulties, and can store a relatively large product without any trouble even when the width of the storage column is limited, and requires less labor and time to reattach the product shelf. In addition, it is an object of the present invention to provide a product storage and conveyance device of a vending machine that can be performed at the same time and that can also minimize the work of reattaching the product shelf itself.

In order to solve the above-mentioned problems and difficulties, the present invention relates to a transport endless body spanned between a pair of transport rotary wheels and a moving direction of the transport endless body. A plurality of product endless members attached to the transport endless body, and a product shelf on which the product is placed, and a region where the product shelf descends in a storage column partitioned in a substantially rectangular shape in plan view And a storage / conveying passage for storing and transporting the product, and a non-storage area in which the transporting endless body is disposed and the product is not stored, and the product is placed in the storage / conveying passage. A product storage / conveyance device for a vending machine configured such that the product shelf is lowered to the lower end position of the transport endless body and rotated downward so that the product is dropped and carried out of the product shelf. In the storage column A product replenishment opening is provided on one side facing the storage conveyance path, and the non-storage area is substantially orthogonal to the side surface of the storage column where the product replenishment opening is provided. A unit partition cover is disposed behind the non-storage area side of the transporting endless body disposed along the side surface and descending.

  With the above configuration, the non-storage area in which the endless body for conveyance is disposed is disposed along the other side surface that is substantially orthogonal to the surface of the storage column adjacent to the surface where the product replenishment opening is provided. The depth dimension of the storage conveyance path is substantially equal to the depth dimension of the storage column, so that a product having a relatively large size equivalent to the depth dimension of the storage conveyance path can be stored.

Further, the present invention is characterized in that a wall surface facing a tip end portion of a product shelf on which products are placed in the storage column is disposed in a fixed state . The configuration of this, the dimensions of the products, even if slightly larger than the depth of the storage conveyance path, by arranging to be inclined so as to prop up against one end of the product to the wall surface, that accommodates the commodity it can. In this case, since the wall surface is in a fixed state, even if a drop prevention door or the like is provided in the product replenishment opening, the product may come out of the storage conveyance path by the opening / closing operation of the drop prevention door. There is no problem.

Further, the present invention is characterized in that a chain cover that covers the transport endless body is disposed in front of the storage transport path side of the transport endless body on the descending side. In the present invention, the transporting endless body is attached with a mounting bracket detachably attached to the product shelf corresponding to a position where the product shelf may be disposed. From the mounting base that is locked to the mounting bracket, the first divided piece that is rotatably attached to the mounting base, and the second divided piece that is rotatably attached to the first divided piece It is characterized by being configured. With this configuration, even when changing the position of the product shelf, it is possible to relatively easily check the mounting bracket at a suitable position and attach the product shelf, and there is a possibility of attaching the product shelf to the wrong mounting bracket. It can be kept low. That is, for example, as compared with the case where a product shelf is attached to a pin of a chain, which is an example of an endless body for conveyance, it is not necessary to attach a product shelf while confirming a large number of pins, thereby reducing labor and time. In addition, it is possible to reduce the occurrence of problems such as attaching to a pin in the wrong place.

Further, the present invention provides the transport endless body spanned between the transport rotating wheels paired up and down, and the transport endless body spaced from each other with respect to the moving direction of the transport endless body. A plurality of endlessly mounted product shelves on which products are placed, and formed in a region where the product shelves descend in storage columns that are partitioned in a substantially rectangular shape in plan view, and store and transport the products And a non-storage area in which the endless body for transfer is disposed and no product is stored, and the product shelf on which the product is placed in the storage and transfer passage is endless for transfer A product storage and transport device of a vending machine configured to drop and unload a product from the product shelf by being lowered to the lower end position of the body and rotated to a posture facing downward, One facing the storage and conveyance passage For goods replenishment opening is provided on the surface, the non-receiving regions are disposed along the other side surface which is substantially perpendicular and adjacent to the one side the commodity replenishing opening is provided in the storage column, Auxiliary merchandise shelves on which small goods can be placed are disposed between the places where the merchandise shelves are attached in the transporting endless body so as to be able to be withdrawn and withdrawn from the storage and transport passage. According to this configuration, when a product to be sold is changed from a large one to a small product to increase the number of items to be stored, the auxiliary product shelf is used to store the product, thereby eliminating the trouble of reattaching the product shelf. be able to.

As described above, according to the present invention, the non-storage area in which the transporting endless body is disposed is placed on the other side surface that is substantially orthogonal to the side surface adjacent to the one side surface in which the product replenishment opening is provided. The unit partition cover is disposed at the rear side of the non-storage area of the conveying endless body that is disposed along the descending side, so that the depth dimension of the storage conveyance path becomes substantially equal to the depth dimension of the storage column. Thus, a relatively large product having a size equivalent to the depth dimension of the storage column can be stored. Therefore, even when the width dimension of the storage column is limited, it is possible to handle many types of products that can be sold, and it is possible to increase the added value as a product storage / conveyance device, and thus a vending machine.

  In addition, by arranging the wall surface facing the tip of the product shelf on which the product is placed in the storage column in a fixed state, it becomes possible to store even a product larger than the depth dimension of the storage column, More types can be handled as products that can be sold, and the added value as a vending machine can be increased. In addition, since the wall surface is fixed, even when an opening / closing door is provided in the product replenishment opening, the opening / closing operation of the opening / closing door may cause the product to fall out of the storage conveyance path. Therefore, good reliability can be obtained.

  In addition, by attaching a mounting bracket that can be attached to and detached from the product shelf to the transport endless body, when changing the position of the product shelf, the possibility of attaching the product shelf to an incorrect position is kept low. It is possible to improve convenience and reliability.

  In addition, by placing an auxiliary product shelf on which a small product can be placed between the places where the product shelf is attached in the transport endless body so that it can be withdrawn from and retracted into the storage transport passage, For example, when it is desired to increase the number of items to be stored by changing from a large product to a small product, the product can be stored using the auxiliary product shelf without reattaching the product shelf, and convenience is improved.

Protective cover members 36 and 37 are disposed in the vicinity of the back surface portion of the motor 24 and in the vicinity of the back surface portion of the sold-out detection lever 32.

  According to the above configuration, as shown in FIGS. 4A and 4B, the non-storage area B in which the drive unit 28 such as the chain 13 as an endless body for conveyance is disposed is provided in the storage column 10. Since the product replenishment opening 9 is disposed along the other side surface (the rear surface in this embodiment) that is orthogonal to the surface on which the product replenishment opening 9 is provided (the right side surface in this embodiment), the storage conveyance path A The depth dimension L3 of the storage column 10 is equal to the depth dimension of the storage column 10, and the product S having the same dimension as the depth dimension of the storage conveyance path A can be stored. Therefore, there is a limitation on the width dimension of the storage column 10 such that the storage stocker 4 provided with the commodity storage and conveyance device 30 must have the same dimensions as the storage stocker often used in general vending machines. Even in some cases, many types of products S including relatively large products S can be handled as products S that can be sold, and the added value as a vending machine can be increased. That is, as in the conventional product storage and transport apparatus shown in FIGS. 16 and 17, in the storage column 50, the non-storage area 57 where the transport endless body 51 and the like are disposed is opposed to the product replenishment opening 59. If it is provided at a location to be stored, it can store only the product 54 that is smaller than the depth dimension of the storage column 50 by a dimension smaller than the dimension of the non-storage area 57 in which the transporting endless body 51 and the like are disposed, Although the trouble that the goods 54 to sell will be limited arises, according to embodiment of this invention, such a trouble does not arise.

  Further, a column partition plate 11b (or a portion forming the back surface of the outer frame body 11a), which is a wall surface facing the tip of the product shelf 14 on which the product S is placed in the storage column 10, is disposed in a fixed state. Therefore, even when the dimension of the product S is slightly larger than the depth dimension of the storage transport passage A as shown by the first and second storage columns 10 (the product storage transport device 30) on the left side in FIG. By disposing one end portion of the product S (the front end portion of the product S in this embodiment) so as to lean against the wall surface (the column partition plate 11b or the portion forming the back surface of the outer frame body 11a). The product S can be stored satisfactorily. In this case, since the wall surface is fixed, even when the drop prevention door 22 is provided in the product replenishment opening 9, the product S comes out of the storage conveyance path A by the opening / closing operation of the drop prevention door 22. There is no inconvenience of falling, and good reliability can be obtained.

  Moreover, according to the said structure, the attachment bracket 35 which can be attached or detached with respect to the goods shelf 14 respond | corresponds to the position where the goods shelf 14 may be arrange | positioned in the chain 13 as an endless body for conveyance. Therefore, even when the position of the product shelf 14 is changed, it is possible to relatively easily check the mounting bracket 35 at a suitable position and attach the product shelf 14 to the wrong mounting bracket 35. The possibility of attaching the product shelf 14 can also be kept low. That is, for example, as compared with the case where the product shelf 53 is directly attached to the pin 51a of the chain 51 as shown in FIG. In addition, it is possible to reduce the occurrence of problems such as attaching to a pin in the wrong place.

  In the above embodiment, the case where only one shape of the product shelf 14 is attached to the mounting bracket 35 is described, but the present invention is not limited to this, and as shown in FIGS. The auxiliary product shelf 41 on which the small product S4 can be placed is stored and transported in the mounting bracket 35 disposed between the portions of the chain 13 as the transport endless body where the product shelf 14 is mounted. You may arrange | position in the channel | path A so that withdrawal / exit is possible. The auxiliary product shelf 41 is different from the product shelf 14 only in that the protruding length into the storage conveyance path A is shorter than that of the product shelf 14, and the other structure is the same as that of the product shelf 14.

  According to this structure, when the product S to be sold is changed from the large product S1 to the small product S2 to increase the number of stored items, the second and third rows from the left in FIG. 14 and the left in FIG. As shown in the column, by storing the product S2 using the auxiliary product shelf 41, the trouble of reattaching the product shelf 14 can be saved. When storing the large product S1, the auxiliary product shelf 41 is folded, so that the large product S1 can be stored and sold without any trouble without reattaching the product shelf 14.

  Further, in the above embodiment, a case where at least one row of storage stockers 4 provided in the vending machine 1 has the above-described structure is described. For example, as another storage stocker, for example, at the time of product delivery, the second from the bottom The case of using a so-called direct-stacking type product storage and conveyance device that pays out only the product at the lower end while pressing the product with a regulating body to prevent the product above it from falling is described. It is not limited. In the above embodiment, the case has been described in which the storage stocker 4 in which a plurality of rows of product storage / conveyance devices 30 and the like are arranged side by side is front and rear, and can be drawn back and forth. Instead, for example, the product storage and conveyance devices 30 are arranged on the left and right, the product replenishment opening 9 is provided in the front, and the non-storage space B in which the drive unit is disposed is placed on the left or right side of the storage column 10. They may be arranged close to each other, and similar effects can be obtained with such a configuration.

  In the above-described embodiment, the case where the chain 13 is used as the transport endless body and the sprockets 12 and 19 are used as the transport rotating ring body is described. However, the present invention is not limited to this. A toothed belt may be used, and a toothed rotating body may be used as the conveying rotating wheel, as long as it can move the product shelf with high accuracy.
