Description

  The present invention relates to a product storage device applied to a vending machine that sells products such as canned drinks and plastic bottled drinks.

  2. Description of the Related Art Conventionally, for example, vending machines that sell products such as canned beverages and plastic bottled beverages have a product storage device that includes a product storage column and a bucket that transports products. The product storage column stores a plurality of products in an aligned state. When the carry-out device is driven, the product storage column pays out products one by one from its front end.

  The bucket is for receiving a product paid out from the product storage column. This bucket is provided so as to be movable up and down and left and right in the front area of the product storage column by bucket driving means. The bucket driving means includes an X-axis transport mechanism that can move the bucket along the left-right direction, and a Y-axis transport mechanism that moves the bucket including the X-axis transport mechanism along the vertical direction. Has been.

  In such a product storage device, when a user inserts money of a predetermined amount or more and operates the product selection button, the bucket driving means is driven and the bucket is placed in front of the product storage column storing the products desired to be purchased. To move. Then, after the commodity is discharged from the commodity storage column to the bucket, the bucket is moved to the vicinity of the commodity outlet. Thereby, the user can take out the product through the product outlet (see, for example, Patent Document 1).

JP 2006-164050 A

  By the way, in the commodity storage device as proposed in the above-mentioned Patent Document 1, it is essential to move the bucket by driving the bucket driving means when paying out the commodity, and various controls are necessary for the movement of the bucket. It is said that. Therefore, the product storage apparatus not only has an excessive number of parts but also requires an expensive sensor and the like, resulting in an increase in cost.

  In view of the above circumstances, an object of the present invention is to provide a product storage device that can reliably take out products stored in a product storage column one by one while reducing costs.

To achieve the above object, the product storage apparatus according to the present onset Ming, a product storage column itself accommodates to line up the products in the product storage passage defining, moves forward and backward relative to the product storage passage In the normal state, it is provided so as to be able to rotate, and in the normal state, the downstream most downstream product is restricted from being taken out and taken out from the product storage passage. A first gate member that allows a product to be taken out, and a first gate member that is pivotably linked to the first gate member in a manner to move forward and backward with respect to the product storage passage. When the first gate member retreats from the product storage passage when the first gate member retreats from the product storage passage, the product moves into the product storage passage when the first gate member retreats from the product storage passage. And a second gate member that regulates the movement of the commodity adjacent to the downstream side, and is normally positioned at a reference position and the first gate member is retracted from the commodity storage passage. While moving from the reference position, the product is stored by being urged by a first slide member for bringing the first gate member into a free state and a biasing means in a normal state. When the second gate member advances into the product storage passage while being in contact with the second gate member retracting from the passage and the first gate member retracting from the product storage passage, A lock member that moves above the gate member and holds the second gate member in a posture of being advanced into the product storage passage, and is normally positioned at a reference position to make the lock member free. When moving from the reference position, a sales command is given, and a second slide member that disengages the lock member from above the second gate member by moving the lock member against the biasing force of the biasing means. In this case, the first slide member is brought into contact with the first slide member and moved from the reference position. On the other hand, when a release command or a refill command is given, the first slide member and the first slide member are moved. A switching cam member that contacts the two slide members and moves the first slide member and the second slide member from the reference position; and, in a normal state, the switching cam member, and the first slide member and the second slide located at the reference position. By contacting at least one of the members, the urging force of the cam urging means is brought into a non-engaging posture, while the switching cam member is given a refill command. When the first slide member and the second slide member are moved from the reference position, they are biased by the cam biasing means to be in the engaged posture, and the first slide member and the second slide member are moved from the reference position. An auxiliary cam member for holding, and in a standby state, the first slide member is positioned at a reference position to restrict the first gate member from retreating from the product storage passage, while a sales instruction is given The switching cam member moves the first slide member from the reference position to allow the first gate member and the second gate member to be in a free state, and allows the most downstream product to be taken out. When the product is taken out, the lock member moves above the second gate member that has advanced into the product storage passage and advances the second gate member into the product storage passage. Characterized by being adapted to hold the energized.

  In the product storage device of the present invention, the first slide member is normally positioned at the reference position and restricts the first gate member from retracting from the product storage passage, so that the product stored in the product storage column is taken out. Can be suppressed. Further, when the sales command is given, the switching cam member moves the first slide member from the reference position, so that the first gate member can be set free and the second gate member can be set free. it can. In this case, when the most downstream product in the product storage passage is taken out by the user, the first gate member retreats from the product storage passage, and the second gate member advances into the product storage passage. When the second gate member advances into the product storage passage, the lock member moves above the second gate member, so that the second gate member is held in the posture of entering the product storage passage. This restricts the product adjacent to the upstream side of the most downstream product from moving to the downstream side. Furthermore, when the release command is given, the switching cam member moves not only the first slide member but also the second slide member from the reference position, so that the lock member can be detached from above the second gate member, Accordingly, the first gate member can be advanced into the product storage passage, and the second gate member can be retracted from the product storage passage. Thus, by entrusting the user to take out the product, it is not necessary to use a bucket or bucket driving means as in a conventional vending machine, and the cost can be reduced. Moreover, even if the first gate member is retracted from the product storage passage, the second gate member advances into the product storage passage, so that the products can be taken out one by one from the product storage column. Therefore, it is possible to reliably take out the products stored in the product storage column one by one while reducing the cost. Further, the auxiliary cam member normally does not resist the biasing force of the cam biasing means by contacting the switching cam member and at least one of the first slide member and the second slide member located at the reference position. On the other hand, when the switching cam member moves the first slide member and the second slide member from the reference position when a replenishment command is given, the cam biasing means biases the engagement posture. Since the first slide member and the second slide member are held in a state of being moved from the reference position, the return load from the first slide member and the second slide member is transmitted to the switching cam member, and the drive source of the switching cam member For example, it is possible to prevent an unnecessary load from acting on the above.

  Next, the take-out mechanism 50 will be described. As shown in FIG. 11, the take-out mechanism 50 is provided for each product storage column 33.

  FIG. 24 schematically shows the product storage column 33 constituting the product rack 30a shown in FIG. 11, and is a longitudinal sectional view showing the case when viewed from the right side. 25 is a perspective view showing the take-out mechanism 50, FIG. 26 is an exploded perspective view of main elements of the take-out mechanism 50, and FIG. 27 is a side view of the take-out mechanism 50 viewed from the right side. These are the side views which looked at the extraction mechanism 50 from the left side.

  As shown also in FIG. 24, the take-out mechanism 50 is provided for each product storage column 33. The takeout mechanism 50 includes a first gate member 51 and a second gate member 52.

  The first gate member 51 extends in the left-right direction and is supported by a gate shaft portion 53 that is installed in an upper region of the foremost product, and a first base end portion 511, and the first base end portion 511. Is also provided with a first tip portion 512 that extends toward the front side and projects downward from the middle thereof. A sliding portion 512a constituting a curved surface is provided at a lower portion of the first tip portion 512. The first gate member 51 can be rotated around the central axis about the central axis of the gate shaft portion 53. A gate spring member 54 is interposed between the first gate member 51 and the gate shaft portion 53. Therefore, the first gate member 51 is biased by the gate spring member 54 and rotated downward, and the first tip portion 512 has advanced into the product storage passage 33a.

  Thus, when the 1st front-end | tip part 512 of the 1st gate member 51 has advanced into the goods storage channel | path 33a, this 1st front-end | tip part 512 is located in the front area of the foremost goods. When the first gate member 51 is rotated upward against the biasing force of the gate spring member 54, the first tip portion 512 is retracted from the product storage passage 33a.

  Such a second gate member 52 is connected to the first gate member 51 via a coil spring member 55. More specifically, when the coil spring member 55 is hooked between the hook groove 516 of the first gate member 51 and the hook groove 526 of the second gate member 52, the coil spring member 55 is urged to the first gate. The positional relationship between the member 51 and the second gate member 52 is defined.

  As a result, when the first tip 512 of the first gate member 51 has advanced into the product storage passage 33a, the second gate member 52 has its second tip 522 retracted from the product storage passage 33a. It is a posture. On the other hand, when the first front end portion 512 of the first gate member 51 is retracted from the product storage passage 33a, the second front end portion 522 is in a posture of being advanced into the product storage passage 33a. Thus, when the 2nd front-end | tip part 522 has advanced into the goods storage channel | path 33a, this 2nd front-end | tip part 522 is located in the front area of the 2nd goods from the forefront.

  The second gate member 52 includes a second engagement piece 523 that protrudes leftward. The second engagement piece 523 enters and locks into a recess on the front side of the first engagement piece 513 in the first gate member 51.

  Since the second gate member 52 is connected to the first gate member 51 via the coil spring member 55, the second gate member 52 basically rotates integrally with the first gate member 51. However, the second gate member 52 rotates upward against the urging force of the coil spring member 55 when a force for retracting the second tip 522 from the product storage passage 33a is applied. is there.

  FIG. 29 is an explanatory view schematically showing the restricting means 60 constituting the product storage device 20 shown in FIGS. 3 and 11. The restricting means 60 includes a guide member 61 and a piece member 62. The guide member 61 is provided in each of the product racks 30a to 30d so as to extend along the left-right direction in the upper front area of each product storage column 33.

  A plurality of piece members 62 are provided. These piece members 62 are accommodated in the accommodation area 61a of the guide member 61 so as to be slidable in the left-right direction. The total width of the spaces S1 and S2 formed in the accommodation area 61a in the restricting means 60 is slightly larger than the width of the protrusion 512b of the first gate member 51 constituting the take-out mechanism 50. .

  Therefore, as shown in FIG. 29 (b), when the protruding portion 512b of any one of the first gate members 51 enters the accommodation area 61a among the take-out mechanisms 50 arranged in each product storage column 33. In the accommodation area 61a, there is no space in which the protrusion 512b of the first gate member 51 of the other extraction mechanism 50 can enter.

  As described above, when the protrusion 512b of the first tip portion 512 of the first gate member 51 that retreats from the product storage passage 33a according to the product take-out operation enters the storage area 61a, The protrusion 512b of the first tip 512 of the first gate member 51 in the take-out mechanism 50 is prevented from entering the receiving area 61a, and the first gate member 51 in the other take-out mechanism 50 is turned upward. Is to regulate.

  FIG. 30 is a flowchart showing the main processing contents of the sales control processing executed by the control means 100 shown in FIG. The operation of the vending machine including the product storage device 20 will be described while explaining the sales control process.

  In the sales control process, the control means 100 validates the corresponding rack selection button 13 when the input amount (amount information) given from the money processing device 16 is equal to or higher than the commodity price (step S101: Yes). (Step S102).

  When the rack selection button 13 associated with the uppermost product rack 30a among the valid rack selection buttons 13 is pressed (step S103: Yes), the control unit 100 presses the rack selection button pressed. The light source 13a built in 13 is turned on according to a predetermined pattern (step S104). In step S104, the light source 13a is always turned on. Then, after executing step S104, the control unit 100 drives the motor M on the assumption that the sales instruction is given (step S105).

  When the “60 ° rotation position” is detected by the mode detection switch 6 (step S106: Yes), the control unit 100 stops driving the motor M and sets the light source 13a that is always lit in step S104 to a predetermined value. For example, blinking is performed according to the pattern (steps S107 and S108).

  And after implementing this step S108, the control means 100 drives the locking / unlocking mechanism 3 to make it unlocked (step S109). As a result, the user can move the outer door 2 open.

  Further, since the support rod 44 is stopped at the “60 ° rotation position”, the support rod 44 is rotated 60 ° clockwise from the “standby position”, and the first projecting piece 45a1 of the first switching cam member 45a is attached to the first slide plate 41. It abuts on the first slide abutting portion 414. As a result, the first slide plate 41 moves toward the left against the urging force of the first slide spring member 415, as shown in FIG.

  When the first slide plate 41 moves leftward in this way, the restriction piece 411b of the first slide plate 41 is detached from the lower region of the first engagement piece 513 of the first gate member 51, and the notch 412a is formed. The lower region of the first engagement piece 513 is opened. As a result, the first gate member 51 of each take-out mechanism 50 in the uppermost product rack 30a is urged by the gate spring member 54, but is free to rotate upward.

  By the way, in the product racks 30b to 30d other than the uppermost product rack 30a, the switching cam member 45 (second switching cam member 45b, third switching cam) attached at a height level corresponding to each product rack 30b to 30d. The member 45c and the fourth switching cam member 45d) are not in contact with the first slide contact portion 414 (see FIG. 18). Therefore, in the product racks 30 b to 30 d other than the uppermost stage, the first gate member 51 of the take-out mechanism 50 arranged in each product storage column 33 is regulated by the first slide plate 41. Therefore, in these product racks 30b to 30d, the products stored in the product storage columns 33 are prevented from being taken out.

  As described above, in the standby state, the rack selection mechanism 40 places all the product racks 30a to 30d in a state in which the removal of the product is restricted. On the other hand, when a sales instruction is given, the product rack 30a at the designated stage is provided. Only allow the product to be removed.

  Then, when the user performs a take-out operation to pull out the foremost product stored in, for example, the first product storage column 33 from the right of the product rack 30a, the take-out mechanism 50 operates as follows. As shown in FIG. 32, the first gate member 51 rotates upward so that the first tip portion 512 is retracted from the product storage passage 33a against the biasing force of the gate spring member 54. In this case, the second gate member 52 also rotates downward integrally with the first gate member 51 so that the second tip 522 advances into the product storage passage 33a. Thereby, the 2nd front-end | tip part 522 of the 2nd gate member 52 is located between the forefront goods taken out and the 2nd goods from the forefront.

  When the second gate member 52 rotates downward as described above, as shown in FIG. 33, the first gate member 51 rotates upward and the lock member 43 is urged by the lock spring member 436 to the right. Move towards you. And the protrusion piece 431a of the lock member 43 is located above the 2nd engagement piece 523 of the 2nd gate member 52, and, thereby, the 2nd gate member 52 is hold | maintained at the attitude | position rotated toward the downward direction. Thereby, the 1st gate member 51 is also hold | maintained at the attitude | position rotated toward upper direction. Therefore, the product stored on the rear side of the second product from the front cannot be moved forward, and a plurality of products can be restricted from being taken out forward in the same product storage column 33. .

  Further, in the first gate member 51 rotated upward, the protruding portion 512 b of the first tip end portion 512 enters the accommodation area 61 a of the guide member 61 constituting the restricting means 60. As a result, the first gate member 51 of the take-out mechanism 50 disposed in the other product storage column 33 in the uppermost product rack 30 a enters the receiving area 61 a of the guide member 61 due to the presence of the piece member 62. And is consequently unable to rotate upwards. Accordingly, it is possible to prevent the product from being taken out from the other product storage column 33 in the same product rack 30a.

  Here, the most recent product is taken out in the following posture. As described above, the rail member 34 is configured such that the front end portion (downstream side end portion) is curved in such a manner that the lower end portion gradually inclines downward, and the rear end portion 35a is regulated in a manner to advance into the product storage passage 33a. A member 35 is provided. Thereby, the foremost product is taken out in a forward leaning posture as shown in FIG. 32 without being taken out while maintaining the standing posture. That is, the restricting member 35 is provided in a lower area of the product storage passage 33a on the front side of the front product, and restricts the front product from being taken out in a standing posture and allows the front product to be taken out in a forward tilt posture. It is.

  In this way, when the user removes the last product from the predetermined product storage column 33, the take-out detection sensor 5 disposed in the product storage column 33 detects that fact and sends a detection signal to the control means 100. Will give.

  When a detection signal is given from the take-out detection sensor 5 and the outer door 2 is then closed and the door switch 4 is switched from the off state to the on state (step S110: Yes, step S111: Yes), the control means 100 It can be recognized that the front opening of the main body cabinet 1 is closed after the commodity is taken out.

  After recognizing such control, the control means 100 drives the locking / unlocking mechanism 3 to the locked state, and then turns off the light source 13a that has been turned on and off (steps S112 and S113). Thereafter, the control means 100 gives a take-out command output to the money processing device 16 and gives a release command to the motor M to drive it (steps S114 and S115).

  In the money processing apparatus 16 to which the withdrawal command output is given from the control means 100, when there is a change, the change is paid out to the coin return port 17, and the money corresponding to the commodity price is accommodated for each denomination.

  Further, by driving the motor M, the support rod 44 is rotated clockwise to the “standby position” which is a predetermined stop position.

  With the rotation of the support rod 44, the first switching cam member 45 a comes into contact with the second slide contact portion 424 of the second slide plate 42, with the second projecting piece 45 a 2 continuing from the first projecting piece 45 a 1. As a result, the second slide plate 42 moves to the left against the urging force of the second slide spring member 425. By moving the second slide plate 42 toward the left, the lock member 43 also moves toward the left against the urging force of the lock spring member 436 and is detached from above the second gate member 52. As a result, the upper region of the second gate member 52 is opened. Accordingly, the first gate member 51 is urged by the gate spring member 54 to rotate downward, and the second gate member 52 is also rotated upward. And the 1st front-end | tip part 512 of the 1st gate member 51 advances into the goods storage path 33a, and the 2nd front-end | tip part 522 of the 2nd gate member 52 retracts | saves from the goods storage path 33a. The product stored in the product storage passage 33a is pressed by the pusher member 343 and brought to the front side.

  Thereafter, when the contact between the second projecting piece 45a2 of the first switching cam member 45a and the first slide contact portion 414 and the second slide contact portion 424 is released by the rotation of the support rod 44, the first slide The plate 41 and the second slide plate 42 are urged by the first slide spring member 415 and the second slide spring member 425, respectively, move toward the right and return to the original state. Then, the restriction piece 411b of the first slide plate 41 is positioned below the first engagement piece 513 of the first gate member 51. Therefore, the first gate member 51 cannot be rotated upward.

  When the predetermined position, that is, the “standby position” is detected by the mode detection switch 6 (step S116: Yes), the control unit 100 stops driving the motor M (step S117), and then returns the procedure. To end the current process. According to this, one product selected by the user can be sold.

  On the other hand, when the door switch 4 is switched from the off state to the on state without receiving a detection signal from the take-out detection sensor 5 in the above step S110 (step S110: No, step S118: Yes), the control means 100 It can be recognized that the front opening of the main body cabinet 1 is closed without being taken out.

  After recognizing such control, the control means 100 drives the locking / unlocking mechanism 3 to the locked state, and then turns off the light source 13a that has been turned on and off (steps S119 and S120). Thereafter, the control means 100 gives a non-withdrawal command output to the money processing apparatus 16 (step S121). The money processing apparatus 16 to which the undrawn command output is given from the control means 100 pays out the inserted coins to the coin return port 17.

  Then, the control means 100 that has given the unremoved command output gives a release command to drive the motor M (step S122), and then returns to the procedure after performing the above-described steps S117 and S118. Terminate the process.

  Next, the case where a product is replenished in the vending machine will be described. FIG. 34 is a flowchart showing the main processing contents of the replenishment control processing performed by the control means 100 shown in FIG. The case where a product is replenished in the vending machine provided with the product storage device 20 will be described while explaining the replenishment control process.

  In the replenishment control process, when the mode selection button 14 is pressed by the administrator (step S103: Yes), the control unit 100 drives the motor M assuming that a replenishment command is given (step S132).

  When the “300 ° rotation position” is detected as a predetermined position by the mode detection switch 6 (step S133: Yes), the control unit 100 stops driving the motor M and drives the locking / unlocking mechanism 3 to unlock the motor M. A locked state is set (steps S134 and S135). Thereby, the administrator can move the outer door 2 open.

  Here, at the “300 ° rotation position”, as described with reference to FIG. 23, the third projecting pieces 45a3, 45b3, 45c3, and 45d3 of all the switching cam members 45 are the first slide plates in the product racks 30a to 30d. 41, the first slide contact portion 414 of the second slide contact portion 424 and the second slide contact portion 424 of the second slide plate 42 are contacted and moved to the left, and then the tip of the auxiliary cam member 46 rotated to the engagement posture. The portion 462 contacts the first slide protrusion 414a of the first slide contact portion 414 and the second slide protrusion 424a of the second slide contact portion 424, and the first slide plate 41 and the second slide plate 42 are used as a reference. It keeps moving from the position to the left.

  Thus, since the first slide plate 41 and the second slide plate 42 are held in a state of moving leftward from the reference position, the first gate member 51 of the take-out mechanism 50 rotates upward. It becomes possible.

  Then, as shown in FIG. 35, the supplementary product is caused to enter the product storage passage 33a from the front side. As described with reference to FIG. 10, when the restricting member 35 is pressed by a product that has entered from the front, the restricting member 35 is moved downward around the central axis of the restricting shaft portion 352 against the urging force of the restricting spring member 353. The rear end portion 35a is retracted from the product storage passage 33a by rotating toward the product storage passage 33a. Therefore, the supplementary product can enter the product storage passage 33a in a standing posture.

  When the supplementary product is made to enter the product storage passage 33a in the standing posture as described above, the cap 200 of the supplementary product slides in contact with the sliding portion 512a at the first tip portion 512 of the first gate member 51. Become. In this case, since the sliding part 512a of the first gate member 51 constitutes a curved surface, the first gate member 51 rotates upward by being pressed by the supplementary product. As a result, the second gate member 52 rotates downward according to the rotation of the first gate member 51.

  Therefore, as shown in FIG. 36, the entered product comes into contact with the second tip 522 of the second gate member 52. The second gate member 52 is rotated by the lock member 43. Since it is not restricted, as shown in FIG. 37, it rotates upward against the biasing force of the coil spring member 55 and the second tip 522 is retracted from the product storage passage 33a. Therefore, a predetermined number of products can be entered from the front area of the product storage column 33 and replenished.

  When the administrator presses the release button 15 after replenishing a predetermined number of products in this way (step S136: Yes), the control means 100 drives the locking / unlocking mechanism 3. After being locked, the release command is given to the motor M to drive it (steps S137 and S138).

  When the predetermined position, that is, the “standby position” is detected by the mode detection switch 6 (step S139: Yes), the control unit 100 stops driving the motor M (step S140), and then returns the procedure. To end the current process.

  As described above, in the vending machine according to the embodiment of the present invention, the rack selection mechanism 40 puts all the product racks 30a to 30d into a state in which the removal of the products is restricted in the standby state. Then, when a sales instruction is given, the rack selection mechanism 40 sets the product rack (30a) at the designated level to allow the product to be taken out. The take-out mechanism 50 disposed for each product storage column 33 normally restricts the removal of products stored in the product storage column 33, while the product rack (30a) having the product storage column 33 has a product rack (30a). If the rack selection mechanism 40 permits the removal of the product, it operates according to the product take-out operation to allow only the foremost product to be taken out. The restricting means 60 provided for each product rack (30a) has one of the take-out mechanisms 50 when the product selection of the product rack (30a) in which the product rack (30a) is provided is permitted by the rack selection mechanism 40. Is allowed to operate, and the other take-out mechanisms 50 in the commodity rack (30a) are restricted from operating. As a result, the user can purchase the desired product without using the bucket driving means as in a conventional vending machine. In addition, it is possible to retain the original function of a vending machine that sells products unattended. Therefore, the cost can be reduced by reducing the number of parts.

  In the product storage device 20 constituting the vending machine, the first slide plate 41 is normally positioned at the reference position and restricts the first gate member 51 from retracting from the product storage passage 33a. It can suppress that the goods stored in the column 33 are taken out. Further, the switching cam member 45 moves the first slide plate 41 from the reference position, whereby the first gate member 51 and the second gate member 52 can be brought into a free state. In this case, when the user takes out the foremost product in the product storage passage 33a, the first gate member 51 is retracted from the product storage passage 33a, and the second gate member 52 advances into the product storage passage 33a. When the second gate member 52 advances into the product storage passage 33a, the lock member 43 moves above the second engagement piece 523 of the second gate member 52, so that the second gate member 52 advances into the product storage passage 33a. Held in the same posture. This restricts the second product from the forefront from moving forward. Further, when the switching cam member 45 moves not only the first slide plate 41 but also the second slide member from the reference position, the lock member 43 is disengaged from above the second engagement piece 523 of the second gate member 52. Thus, the first gate member 51 can be advanced into the product storage passage 33a, and the second gate member 52 can be retracted from the product storage passage 33a. Thus, by entrusting the user to take out the product, it is not necessary to use a bucket or bucket driving means as in a conventional vending machine, and the cost can be reduced. Moreover, even if the first gate member 51 is retracted from the product storage passage 33a, the second gate member 52 advances into the product storage passage 33a, so that the products can be taken out from the product storage column 33 one by one. Therefore, the products stored in the product storage column 33 can be reliably taken out one by one while reducing the cost.

  In the product storage device 20 that constitutes the vending machine, the rail member 34 that constitutes each product storage column 33 supports the product cap mounting portion 200a to suspend the product in an upright position. Since it is stored in the storage passage 33a, it is possible to satisfactorily store the product in which the body portion 201 is stored in a deformed container such as a flat shape without causing product clogging.

  In the product storage device 20 constituting the vending machine, the protrusion 512b of the first gate member 51 that the regulating means 60 rotates upward in response to the product take-out operation has entered the storage area 61a. In this case, the protrusion 512b of the first gate member 51 in the other extraction mechanism 50 is prevented from entering the accommodation area 61a, and the backward movement of the first gate member 51 in the other extraction mechanism 50 is restricted. Thereby, it can prevent reliably that a some goods are taken out from one goods rack 30a-30d.

  In the product storage device 20 constituting the vending machine, since the product is stored in the product storage passage 33a in a standing posture, the product is placed horizontally as in the prior art described in, for example, Japanese Patent Publication No. 50-27749. Compared to the case where the product is stored in a tilted position and the product is viewed from the cap 200 side, the entire product can be visually recognized by the user, and the user can directly see and touch the purchased product. Can give the user a sense of security.

  In addition, the vending machine and the product storage device 20 can provide the following operational effects.

  Since the regulating member 35 in the product storage device 20 regulates that the foremost product is taken out in a standing posture and allows it to be taken out in a forward inclined posture, the take-out posture of the product can be controlled, Thereby, it is possible to suppress the user from taking out in an arbitrary posture, and it is possible to prevent the occurrence of a failure or the like induced by the user being taken out in an arbitrary posture. In particular, since the front end portion (downstream end portion) of the rail member 34 is curved in such a manner that the rail member 34 is gradually inclined downward, the product stored while being suspended on the rail member 34 is also reliably inclined forward. Can be taken out in a posture.

  In the above replenishment control process, as an example when the administrator depresses the mode selection button 14, the product replenishment has been described. However, in the vending machine according to the present embodiment, each product storage column 33 includes By pressing the mode selection button 14 by the administrator while the product is already replenished, the function as a refrigerated showcase can be exhibited instead of as a vending machine. That is, when the mode selection button 14 is pressed, the outer door 2 can be opened and closed by the locking / unlocking mechanism 3, and the removal of the products is permitted in all the product racks 30a to 30d. Accordingly, the user can open the outer door 2 and take out a desired product.

  The first gate member 51 and the second gate member 52 in the take-out mechanism 50 of the product storage device 20 are rotatable around the central axis of the common gate shaft portion 53, and the gate shaft portion 53 is the foremost product. It is provided in the upper area. Thereby, the distance between the first tip portion 512 of the first gate member 51 and the gate shaft portion 53 and the distance between the second tip portion 522 of the second gate member 52 and the gate shaft portion 53 can be shortened. A sufficient rotation distance between the first gate member 51 and the second gate member 52 can be secured. Further, when the first gate member 51 is released from being held in the state of being advanced into the product storage passage 33a, the sliding portion 512a of the first gate member 51 is in the state of advancement of the product storage passage 33a. When it is pressed while sliding on a product that has entered from the front side, the manager retreats from the product storage passage 33a to allow the product to enter, so that the administrator replenishes the product with only one hand without using both hands. It is possible to improve work efficiency.

  In the product storage device 20, the slide base member 322 that supports the first slide plate 41 and the second slide plate 42, and the cam base members 441 a to 441 d that support the cam mechanism include a guide protrusion 3221 formed on one side. Since the guide recess 4412 formed on the other side is engaged by fitting with each other, the first slide plate 41 and the second slide plate 42 supported by the slide base member 322 and the cam base members 441a to 441d are engaged. Positioning with the supported cam mechanism (the switching cam member 45 and the auxiliary cam member 46) can be performed with sufficiently high accuracy.

  In the product storage device 20, when the “300 ° rotation position” is set, the auxiliary cam member 46 is engaged and the first slide plate 41 and the second slide plate 42 are moved leftward from the reference position. Therefore, it is possible to prevent the return load from the first slide plate 41 and the second slide plate 42 from being transmitted to the switching cam member 45 so that an excessive load is applied to the motor M and the like. can do.

  In the vending machine, in the sales control process, the light source 13a built in the pressed rack selection button 13 is lit according to a predetermined pattern, so that the product racks 30a to 30d selected for the user are displayed. In addition to recognizing it, the purchase process can be appealed through the visual senses, which can motivate purchases.

  In the vending machine, the positions of the standby part, the sales part, and the replenishment part of the switching cam member 45 are made to correspond to the respective sides of the support rod 44 so that each position is set to 60 ° when the support rod 44 rotates 360 °. It is possible to arrange them evenly, so that the accuracy of positioning can be improved and the current position can be easily recognized.

  In the vending machine, the product racks 30a to 30d are fastened by a screw member N as a fastening member to a surface (front surface) facing the front opening of the rack support side plate 31 provided in the storage chamber 1a of the main body cabinet 1. Therefore, the operator can open and move the outer door 2 to open the front opening of the main body cabinet 1, and perform the attaching / detaching work of the product racks 30 a to 30 d from the front through the front opening. it can. Therefore, it is possible to easily attach and detach the product racks 30a to 30d and perform other operations at the place where the vending machine is installed.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  In the embodiment described above, one input processing unit 10 is attached to one main body cabinet 1 to constitute a vending machine. However, in the present invention, an input processing unit and a plurality of units that do not include input processing are provided. The vending machines may be configured by connecting one input processing unit and a plurality of main body cabinets by communicably connecting the main body cabinets. This also makes it possible to sell only one product desired by the user and to sell a wide variety of products.

  In addition, the products stored in one product rack may have the same price, but the present invention is not limited to this, and the products stored in one product rack may have different prices for each product storage column. Good. According to this, it becomes possible to sell a multi-price product even in one merchandise rack, and it is possible to increase the number of products sold while being compact as a whole vending machine.

  In embodiment mentioned above, the inside of the main body cabinet 1 can be visually recognized through the window part 2a of the outer door 2. As shown in FIG. In the present invention, not only the door body (outer door) but also the vending machine main body (main body cabinet) is formed of a transparent heat insulating glass material so that a window portion is formed in the vending machine main body. good. According to this, not only a door body but the inside can be visually recognized through the window part of a vending machine main body.
