Description

  The present invention relates to a product dispensing device, and more specifically, a product dispensing that is applied to a vending machine that sells products such as canned beverages and beverages containing plastic bottles, and appropriately transports products stored in a product storage passage. It relates to the device.

  2. Description of the Related Art Conventionally, in a vending machine that sells products such as canned beverages and beverages containing plastic bottles, a product storage rack is provided in a product storage in a main body cabinet that is a main body of the vending machine. The product storage rack includes a product storage passage that extends in the vertical direction, and a product carry-out device that is disposed below the product storage passage.

  The commodity carry-out device includes a lower pedal and an upper pedal. The lower pedal and the upper pedal are linked to an AC solenoid, which is an actuator, via a link. When the AC solenoid is energized, the lower pedal and the upper pedal are moved forward and backward appropriately in the product storage passage.

  In such a product carry-out device, in the standby state, the upper pedal is in a state of retreating from the product storage passage, while the lower pedal is in a state of moving forward into the product storage passage. Thereby, the lower pedal abuts on the lowest product stored in the product storage passage, and the downward movement of the product stored in the product storage passage is restricted.

  When a product delivery instruction is given, in the product delivery device below the product storage passage for storing the corresponding product, the upper pedal advances into the product storage passage via the link when the AC solenoid is energized. By moving and contacting the second lowest product, the product and the product stored above the product are restricted from moving downward. Also, when the AC solenoid is energized, the lower pedal moves backward from the product storage passage, the lowest product is carried out downward only, and when the product passes through the lower pedal, the lower pedal is attached with a spring. Moves into the product storage passage by force. Thereafter, when the energized state of the AC solenoid is released and the energized state is established, the lower pedal that has moved forward into the product storage passage is in a state in which the backward movement is restricted, and the upper pedal is moved backward from the product storage passage. Thus, the standby state described above is restored.

  In the above product storage rack, two product storage passages are generally adjacent to each other in the front and rear, so that the product carry-out device applied to each product storage passage is entangled back to back and arranged in the product storage passage. It is configured to be installed. In such a product carry-out device, an AC solenoid that is a driving source is required for each of the product carry-out devices entangled.

  Therefore, in order to reduce the manufacturing cost by reducing the drive source, the product carry-out devices from which the AC solenoids are removed are back to back with each other, and the drive source and the cam are provided between them. A product dispensing device has been proposed in which each product delivery device is driven by rotation (see, for example, Patent Document 1).

Japanese Patent No. 2749917

  However, in the merchandise dispensing apparatus proposed in Patent Document 1, the merchandise carry-out apparatuses from which the AC solenoids are removed are back to back with each other, and the drive source and cam are provided between them. Although the number of drive sources can be reduced, it is difficult to use only one of the two product carry-out devices separated from each other as a constituent element. In other words, the product dispensing apparatus proposed in Patent Document 1 can be applied to a product storage rack having an even number of product storage passages adjacent to each other in the front and rear directions, but a product storage rack having an odd number of product storage passages may be used. It could not be used as an individual product delivery device. In addition, the product dispensing device is provided with two types of product delivery devices having different widths corresponding to the types of product storage racks, that is, products having a relatively small maximum width and products having a relatively large maximum width. Generally, a product carry-out device having a width corresponding to the maximum width of a product stored in the rack is mounted on the product storage rack.

  In view of the above circumstances, the present invention provides a product dispensing device that can reduce manufacturing costs and can flexibly respond to the number of product storage passages adjacent to each other in the front and rear directions. Objective.

  In order to achieve the above object, a product dispensing apparatus according to the present invention is applied to one product storage passage that stores a product that has been input along the vertical direction. While restricting the movement of the stored product to move downward, when driving, one product unloading device that unloads the lowest-order product stored in the one product storage path, Applied to the other product storage passage that is adjacent to the one product storage passage and stores the introduced product along the vertical direction. In the standby state, the product stored in the other product storage passage is downward. When moving, the other product unloading device for unloading the lowest-order product stored in the other product storage passage downward is entangled back to back with each other. In the product delivery device that can be operated, the one product delivery device is disposed so as to be able to rotate forward and backward around the central axis of the drive source of the product and the other product delivery device. When a carry-out command is given, it rotates in one direction from the predetermined standby position by the driving force from the drive source, while when the other product carry-out device is given a carry-out command, the standby An output member that rotates in the other direction from the position by the driving force from the drive source, and is provided so as to be rotatable about its own axis in correspondence with the product carry-out device, and in a normal state, the corresponding product carry-out device In the unloading standby state, and when the driving force is applied by the rotation of the output member, the link lever that drives the corresponding product unloading device and the standby position by the unloading command. If the output member rotated in the direction or the other direction does not return to the standby position within a predetermined set time, the output member is rotated in the other direction or one direction to return to the standby position. Control means for performing a retry process for rotating the output member in one direction or the other direction, and the control means drives the drive source in the retry process performed in response to the carry-out command. When the number of times is equal to or greater than a predetermined threshold, the driving of the commodity carry-out device is restricted until a predetermined pause time elapses.

  According to the present invention, in the product dispensing device, the drive source is common to the one product delivery device and the other product delivery device.

  According to the present invention, in the product dispensing device, the drive source is a DC motor.

  According to the present invention, when one merchandise unloading device is given a drive source of the one merchandise unloading device and the other merchandise unloading device and a carry-out command, the one product carry-out device is responsive to the carry-out command. Since the apparatus and the other product carry-out device are alternatively selected and provided with drive force applying means for applying drive force from the drive source, the number of drive sources is reduced with respect to the number of product carry-out devices. Manufacturing cost can be reduced. Moreover, since one of the product carry-out devices is provided with the drive source and the driving force applying means, only one of the product carry-out devices can be used. That is, the present invention can be used not only for a product storage device provided with even-numbered product storage passages arranged in the front-rear direction but also for a product storage device provided with odd-numbered product storage passages arranged in the front-rear direction. Accordingly, it is possible to reduce the manufacturing cost and to flexibly cope with the number of commodity storage passages adjacent to each other in the front and rear directions.

  Further, according to the present invention, when the number of times the drive source is driven in the retry process performed in response to the carry-out command is equal to or greater than a predetermined threshold, a predetermined pause time elapses. Since the drive of the product carry-out device is restricted until this time, it is possible to prevent the drive source from being burned out due to a temperature rise.

The pedal operation shaft 361 is a shaft-like member disposed substantially in the horizontal direction, and both ends thereof are fitted into the guide grooves 283 of the lower pedal 28.

  A pedal operation spring (not shown) is interposed between the rotation stopper 36 and the base 21. The pedal operating spring is always urged toward the direction in which the rotation stopper 36 advances and moves with respect to the first product storage passage 13a.

  Such a rotation stopper 36 is urged by a pedal operation spring toward the advancing movement direction with respect to the first product storage passage 13a, and the pedal stopper pin 34b enters the recess 36b of the rotation stopper 36. Thus, movement in the retreating movement direction is restricted by contacting the pedal stopper pin 34b, and an initial position in a state of moving forward with respect to the first commodity storage passage 13a is set. Further, since the lower pedal 28 is biased by the lower pedal spring 28b, both ends of the pedal operation shaft 361 are positioned at the fitting portions 283a of the guide groove 283, and the lower pedal 28 is the first product. An initial position is set at a position where the storage passage 13a has moved forward.

  The pedal link 35 is a long plate-like member extending along the vertical direction, and extends upward after the upper portion is bent forward. A contact piece 351 that extends rearward and then extends obliquely upward is provided on an upper portion of the pedal link 35, and a locking portion 352 that locks the link spring 35a is provided. . The link spring 35a is interposed between the pedal link 35 and the base 21, and always urges the pedal link 35 downward.

In addition, the pedal stopper pin 34b is disposed at the upper end of the pedal stopper pin support grooves 23b4 and 24c2. In this state, the stopper abutting portion 293 of the upper pedal 29 abuts on the stopper pin 34a, so that the backward movement of the upper pedal 29 is restricted, and the upper pedal 29 moves forward against the urging force of the upper pedal spring. And placed in the advance position.

  On the other hand, since the restriction of the backward movement by the pedal stopper pin 34b is released, the turning stopper 36 is released from the restriction of the backward movement around the stopper shaft 34c. Here, the rotation stopper 36 is subjected to a load of a product that is in contact with the lower pedal 28 maintained at the advanced position by the rotation stopper 36, and the restriction of the backward movement of the rotation stopper 36 is released. As a result, the rotation stopper 36 starts to move backward. When the retreating movement of the rotation stopper 36 is started, the pedal operation shaft 361 is disengaged from the fitting portion 283a of the lower pedal 28. Therefore, the lower pedal 28 is allowed to retreat about the first swing support shaft 28a and the product is moved. The load moves backward against the elastic urging force of the lower pedal spring 28b (see FIG. 8).

  When the lower pedal 28 moves backward as described above, the base end portion of the lower pedal 28 is separated from the first sold-out contact portion 32 of the first sold-out link 30 as shown in FIG. One sold-out link 30 is in a free state. Thereby, in the 1st sold-out detection switch 26, the contactor 26a is urged | biased by the spring, and becomes an attitude | position which stood up, and maintains an OFF state.

  The stopper shaft 34c ′ is a shaft-like member disposed substantially horizontally between the bearing portion 24 ′ and the second left bearing piece 23b ′, and supports the rotation stopper 36 ′ at an intermediate portion thereof. ing.

  The rotation stopper 36 ′ is configured such that the stopper shaft 34 c ′ is inserted through the insertion hole in the base end portion and can swing around the central axis of the stopper shaft 34 c ′. 23b '.

  The distal end portion of the rotation stopper 36 ′ extends outward in the radial direction of the stopper shaft 34 c ′, and when the swing stopper 36 ′ swings around the central axis of the stopper shaft 34 c ′, the second end is inserted through the second insertion hole 23 ′. It is possible to move forward and backward in the product storage passage 13b.

  The rotation stopper 36 ′ has the pedal operation shaft 361 ′ by passing a pedal operation shaft 361 ′ (see FIG. 4) through a through hole (not shown) at the tip. The pedal operating shaft 361 'is a shaft-like member disposed substantially in the horizontal direction, and both ends thereof are fitted into the guide grooves of the lower pedal 28'.

  A pedal operation spring (not shown) is interposed between the rotation stopper 36 'and the base 21'. The pedal operation spring is always urged toward the direction in which the rotation stopper 36 'moves forward with respect to the second product storage passage 13b.

  Such a rotation stopper 36 'is urged by a pedal operating spring toward the advancing movement direction with respect to the second product storage passage 13b, and a pedal stopper pin 34b is placed in the recess 36b' of the rotation stopper 36 '. ′ Enters and abuts against the pedal stopper pin 34b ′ to restrict the movement in the backward movement direction, and the initial position in the state where the second product storage passage 13b is advanced is set. Yes. Further, since the lower pedal 28 'is urged by the lower pedal spring 28b', both ends of the pedal operation shaft 361 'are positioned at the guide groove insertion portions, and the lower pedal 28' An initial position is set at a position where the second product storage passage 13b has moved forward.

  The pedal link 35 ′ is a long plate-like member extending in the vertical direction, and extends upward after the upper portion is bent rearward. An abutment piece 351 ′ extending forward and then obliquely upward is provided on the upper portion of the pedal link 35 ′, and a locking portion 352 ′ for locking the link spring 35a ′ is provided. Is provided. The link spring 35a 'is interposed between the pedal link 35' and the base 21 ', and always urges the pedal link 35' downward.

  In a state where the pedal link 35 ′ is urged by the link spring 35 a ′ and disposed below, the recess 292 ′ of the upper pedal 29 ′ disposed at the retreat position is in contact with the stopper pin. In addition, the rotation stopper 36 'disposed at the advanced position is in contact with the pedal stopper pin 34b', and the backward movement of the rotation stopper 36 'is restricted. Further, the pedal operation shaft 361 'of the rotation stopper 36' arranged at the advanced position is fitted into the fitting portion of the lower pedal 28 ', whereby the lower pedal 28' arranged at the advanced position is retracted. It is regulated.

  On the other hand, in a state where the pedal link 35 ′ is disposed above against the urging force of the link spring 35 a ′, the stopper abutting portion 293 ′ of the upper pedal 29 ′ abuts on the stopper pin, so that the upper pedal The retreat movement of 29 'is restricted, and the upper pedal 29' moves forward against the urging force of the upper pedal spring and is disposed at the advance position.

  On the other hand, since the restriction of the backward movement by the pedal stopper pin 34b 'is released, the restriction of the backward movement around the stopper shaft 34c' is released from the rotation stopper 36 '. Here, a load of a product in contact with the lower pedal 28 ′ maintained at the advanced position by the rotation stopper 36 ′ is applied to the rotation stopper 36 ′, and the rotation stopper 36 ′ restricts the backward movement. When the is released, the rotation stopper 36 'starts to move backward. When the retreating movement of the rotation stopper 36 'is started, the pedal operation shaft 361' is disengaged from the fitting portion 283a of the lower pedal 28 ', so that the lower pedal 28' retreats about the first swing support shaft 28a '. It is allowed to move backward against the elastic biasing force of the lower pedal spring 28b 'due to the load of the product.

  When the lower pedal 28 ′ moves backward as described above, the base end portion of the lower pedal 28 ′ is separated from the second sold-out contact portion 52 of the second sold-out link 50, and as a result, the second sold-out link 50. Will be free. Thereby, in the 2nd selling-out detection switch 27, it will be in the stand-up attitude | position by the contactor 27a being urged | biased by a spring, and an OFF state is maintained. That is, when the lower pedal 28 ′ moves backward, the second sold-out link 50 does not press the contact 27 a of the second sold-out detection switch 27, as in the standby state with the product.

  The product delivery device 20 is configured by tying the first product delivery device 20a and the second product delivery device 20b having the above-described configuration back to back using the harness guide 25 as a guide member. In this case, the first link lever 461 constituting the drive unit 40 has a tip portion located below the contact piece 351 of the pedal link 35, and the second link lever 462 has a tip portion pedaled. It is located below the contact piece 351 'of the link 35'.

  FIG. 20 is a block diagram showing a characteristic control system of the commodity dispensing apparatus 20. As shown in FIG. 20, the commodity dispensing apparatus 20 includes a dispensing control unit 50. The payout control unit 50 controls the operation of the product payout device 20 according to programs and data stored in the memory 51 and can communicate with the vending machine control unit 100 that controls the sales operation of the vending machine. Is. Processing performed by the payout control unit 50 will be described later.

  The commodity dispensing apparatus 20 configured as described above is as follows in the standby state. In the following description, the product stored in the first product storage passage 13a is also referred to as “first product”, and the product stored in the second product storage passage 13b is also referred to as “second product”.

  In the drive unit 40 provided in the first product carry-out device 20a, the cam portion 443a and the pressing piece 443b of the output gear 443 are located at the uppermost position, and the pressing piece 443b presses the contact 45a of the carrier switch 45. ing. In this case, the carrier switch 45 is turned on. In such a standby state, the distal end portion 461b of the first link lever 461 constituting the drive unit 40 is at a position spaced downward from the contact piece 351 of the pedal link 35, and the distal end portion 462b of the second link lever 462 is The pedal link 35 'is at a position spaced downward from the contact piece 351' of the pedal link 35 '.

  Therefore, in the 1st goods carrying-out apparatus 20a, as shown in FIG. 5, the pedal link 35 exists in the state arrange | positioned below. In addition, the product placed on the upper surface of the lower pedal 28 by the product introduced into the first product storage passage 13a causes the lower pedal 28 to be in a product-waiting posture, and the upper pedal 29 is stored in the first product storage. The posture is retreated from the passage 13a (see FIG. 23A). Thus, since the lower pedal 28 is in the standby state with the product, the first sold-out detection switch 26 is in the off state with the contact 26a standing up.

  Further, in the second product carry-out device 20b, the pedal link 35 'is in a state of being disposed below, the lower pedal 28' is in a product-holding posture, and the upper pedal 29 'is in the second product storage passage. The posture is retreated from 13b (see FIG. 24A). Thus, since the lower pedal 28 'is in the commodity standby position, the second sold-out detection switch 27 is in the off state with the contact 27a standing.

  In such a product dispensing apparatus 20, when the dispensing control unit 50 inputs the first product unloading command given from the vending machine control unit 100, the motor 43 is driven to rotate forward.

  When the motor 43 is driven to rotate forward in this way, the output gear 443 to which the driving force of the motor 43 is transmitted via the worm gear 441 and the intermediate gear 442 rotates in the clockwise direction when viewed from the front.

  When the output gear 443 rotates clockwise as viewed from the front, the pressing piece 443b of the output gear 443 is detached from the contact 45a of the carrier switch 45. Accordingly, the contact 45a of the carrier switch 45 is released from the pressed state and switched from the on state to the off state, and an off signal is given to the payout control unit 50.

  When the cam portion 443a contacts the base end portion 461a of the first link lever 461 from above by the rotation of the output gear 443, the first link lever 461 rotates counterclockwise as viewed from the front. When the first link lever 461 rotates counterclockwise, the tip end portion 461b moves upward. As shown in FIGS. 21 and 22, the tip portion 461b moves upward as described above, thereby contacting the contact piece 351 of the pedal link 35 and resisting the urging force of the link spring 35a. The link 35 can be moved upward by a predetermined distance, and while the cam portion 443a is in sliding contact with the base end portion 461a, the pedal link 35 can be kept moved upward by a predetermined distance. it can.

  In this case, when the first link lever 461 is in sliding contact with the cam portion 443a, the surface (A) including the portion in sliding contact with the cam portion 443a has its own central axis (the central axis of the first link shaft 42e). The output gear 443 is adjusted so as to be substantially orthogonal to a plane (B) including the stop axis of the output gear 443.

  As the pedal link 35 moves upward, the stopper pin 34a moves upward from the lower ends of the stopper pin insertion holes 23b3 and 24c1, and the pedal stopper pin 34b extends from the lower ends of the pedal stopper pin support grooves 23b4 and 24c2. Move upward.

  At this time, since the stopper pin 34a moves upward while contacting the edge wall of the recess 292 of the upper pedal 29, the upper pedal 29 is initially resisted against the urging force of the upper pedal spring as shown in FIG. Move forward from position. The advance movement of the upper pedal 29 is performed by the upward movement of the stopper pin 34a. Then, when the stopper pin 34a reaches the upper end portions of the stopper pin insertion holes 23b3 and 24c1, the stopper pin 34a contacts the stopper contact portion 293 and restricts the retraction of the upper pedal 29.

  Then, the upper pedal 29 that has moved forward contacts the first product (hereinafter also referred to as the next product) from the lowest position, and restricts the next product from moving downward.

  On the other hand, since the rotation stopper 36 is loaded with a product that is in contact with the lower pedal 28 maintained at the advanced position, the regulation of the backward movement is released by the upward movement of the pedal stopper pin 34b. As a result, the rotation stopper 36 starts to move backward.

  Thus, when the rotation stopper 36 starts to move backward, the pedal operation shaft 361 comes out of the fitting portion 283a, and the lower pedal 28 starts moving backward against the urging force of the lower pedal spring 28b by the weight of the product. The pedal operation shaft 361 of the rotation stopper 36 that has come out of the fitting portion 283a moves along the first guide portion 283b toward the position where the first guide portion 283b and the second guide portion 283c intersect.

  Thereafter, as shown in FIG. 23 (c), the lower pedal 28 moves backward due to the weight of the lowest product, and the downward movement of the lowest product is allowed, and the lowest product is carried out downward. (See FIG. 8). The carried-out merchandise is guided to the merchandise carry-out port 3c through the merchandise shooter 5 and can be taken out via the merchandise take-out port 2a.

  Here, when the lowest product passes through the lower pedal 28, the lower pedal 28 is moved toward the advanced position by the elastic biasing force of the lower pedal spring 28b, and the rotation stopper 36 is also moved by the elastic biasing force of the pedal operating spring. Move toward the advance position. When the lower pedal 28 and the rotation stopper 36 move toward the advanced position, the pedal operation shaft 361 held at the position where the first guide portion 283b and the second guide portion 283c intersect with each other moves toward the insertion portion 283a. 2 It moves along the guide part 283c, and the lower pedal 28 and the rotation stopper 36 return to the advance position.

  During this time, the pedal link 35 moves upward, the stopper pin 34a is positioned at the upper end of the stopper pin insertion holes 23b3 and 24c1, and the pedal stopper pin 34b is positioned at the upper end of the pedal stopper pin support grooves 23b4 and 24c2. become.

  Thereafter, when the contact between the cam portion 443a and the base end portion 462a is released by the rotation of the output gear 443, the pedal link 35 is urged by the link spring 35a and moves downward.

  The downward movement of the pedal link 35 causes the stopper pin 34a to move downward from the upper end portions of the stopper pin insertion holes 23b3 and 24c1, and the pedal stopper pin 34b moves downward from the upper end portions of the pedal stopper pin support grooves 23b4 and 24c2. Move to.

  When the pedal stopper pin 34b moves to the lower ends of the pedal stopper pin support grooves 23b4 and 24c2, the pedal stopper pin 34b comes into contact with the recess 36b on the back side of the rotation stopper 36 that has returned to the advanced position. As a result, the movement in the backward movement direction is restricted, and as shown in FIG. 23 (d), the lower pedal 28 moves forward with respect to the first product storage passage 13a by the urging force of the lower pedal spring 28b. Return to posture. As a result, the first sold-out detection switch 26 is switched from the off state to the on state, and an on signal is given to the payout control unit 50.

  On the other hand, the upper pedal 29 is urged by the upper pedal spring and moves backward as the stopper pin 34a moves downward. As a result, the downward movement of the next product is allowed, and then the next product abuts on the lower pedal 28 that has moved forward, and the downward movement is restricted. On the other hand, as shown in FIG. No. 28 shifts to a standby state with a product and returns to a standby state.

  In the drive unit 40, the cam portion 443 a then comes into contact with the base end portion 462 a of the second link lever 462 due to the rotation along the clockwise direction when viewed from the front of the output gear 443. In this case, the second link lever 462 is restricted from rotating about the central axis because the locking portion 462c is in contact with the right edge 472 of the left opening. Therefore, the locking portion 462c is elastically deformed so as to allow the proximal end portion 462a to approach the locking portion 462c, and does not hinder the movement of the cam portion 443a due to the rotation of the output gear 443.

  Then, when the cam portion 443a returns to the standby position by the rotation of the output gear 443, the pressing piece 443b presses the contact 45a of the carrier switch 45, and the carrier switch 45 switches from the OFF state to the ON state, and the ON signal Is given to the payout control unit 50. Immediately after the pressing piece 443b presses the contact 45a of the carrier switch 45, the cam portion 443a is detached from the base end portion 462a of the second link lever 462, and the second link lever 462 is returned to the original state by the locking portion 462c. Return. Thereafter, the payout control unit 50 stops driving the motor 43.

  On the other hand, in the product dispensing device 20, when the dispensing control unit 50 inputs the second product carry-out command given from the vending machine control unit 100, the motor 43 is driven in reverse.

  When the motor 43 is driven in reverse as described above, the output gear 443 to which the driving force of the motor 43 is transmitted via the worm gear 441 and the intermediate gear 442 rotates in the counterclockwise direction when viewed from the front.

  When the output gear 443 rotates counterclockwise when viewed from the front, the pressing piece 443b of the output gear 443 is detached from the contact 45a of the carrier switch 45. Accordingly, the contact 45a of the carrier switch 45 is released from the pressed state and switched from the on state to the off state, and an off signal is given to the payout control unit 50.

  When the cam portion 443a comes into contact with the base end portion 462a of the second link lever 462 from above by the rotation of the output gear 443, the second link lever 462 rotates in the clockwise direction when viewed from the front. When the second link lever 462 rotates in the clockwise direction, the tip end portion 462b moves upward. In this way, the distal end portion 462b moves upward to contact the contact piece 351 ′ of the pedal link 35 ′, and the pedal link 35 ′ is directed upward against the urging force of the link spring 35a ′. Further, while the cam portion 443a is in sliding contact with the base end portion 462a, the pedal link 35 'can be kept moved upward by a predetermined distance.

  In this case, the second link lever 462 is not clearly shown in the drawing, but when the second link lever 462 is in sliding contact with the cam portion 443a, the surface including the portion in sliding contact with the cam portion 443a has its own central axis (the center of the second link shaft 42f). Axis) and a plane including the stop axis of the output gear 443 is adjusted so as to be substantially orthogonal.

  As the pedal link 35 'moves upward, the stopper pin moves upward and the pedal stopper pin 34b' also moves upward.

  At this time, the stopper pin moves upward while coming into contact with the edge wall of the recess 292 'of the upper pedal 29', so that the upper pedal 29 'resists the urging force of the upper pedal spring as shown in FIG. Then move forward from the initial position. The advancement movement of the upper pedal 29 'is performed by the upward movement of the stopper pin. When the stopper pin reaches the upper end portion of the stopper pin insertion hole, the stopper pin abuts against the stopper abutting portion 293 'to restrict the retraction of the upper pedal 29'.

  Then, the upper pedal 29 ′ that has moved forward contacts the second product from the lowest (hereinafter also referred to as the next product), and restricts the next product from moving downward.

  On the other hand, since the rotation stopper 36 'is loaded with a product abutting against the lower pedal 28' maintained at the advanced position, the backward movement is restricted by the upward movement of the pedal stopper pin 34b '. As a result of the release, the rotation stopper 36 'starts to move backward.

  When the rotation stopper 36 'starts to move backward as described above, the pedal operation shaft 361' comes out of the fitting portion, and the lower pedal 28 'starts moving backward against the urging force of the lower pedal spring 28b' by the weight of the product. To do. The pedal operation shaft 361 ′ of the rotation stopper 36 ′ that has come out of the fitting portion moves along the first guide portion toward the position where the first guide portion and the second guide portion intersect.

  Thereafter, as shown in FIG. 24C, the lower pedal 28 'moves backward due to the weight of the lowest product, and the downward movement of the lowest product is allowed, and the lowest product is moved downward. It is carried out. The carried-out merchandise is guided to the merchandise carry-out port 3c through the merchandise shooter 5 and can be taken out via the merchandise take-out port 2a.

  Here, when the lowest product slips through the lower pedal 28 ', the lower pedal 28' is moved toward the advanced position by the elastic biasing force of the lower pedal spring 28b ', and the rotation stopper 36' is also a pedal operating spring. It moves toward the advance position by the elastic biasing force. When the lower pedal 28 ′ and the rotation stopper 36 ′ move toward the advanced position, the pedal operation shaft 361 ′ held at the position where the first guide portion and the second guide portion intersect with each other toward the insertion portion. 2 Move along the guide, and the lower pedal 28 'and the rotation stopper 36' return to the advanced position.

  Thereafter, when the contact between the cam portion 443a and the base end portion 462a is released by the rotation of the output gear 443, the pedal link 35 'is urged by the link spring 35a' and moves downward.

  Due to the downward movement of the pedal link 35 ', the stopper pin moves downward and the pedal stopper pin 34b' also moves downward.

  When the pedal stopper pin 34b 'moves to the lower end of the pedal stopper pin support groove, the pedal stopper pin 34b' comes into contact with the recess 36b 'on the back side of the rotation stopper 36' that has returned to the advanced position. As a result, the movement in the retreating movement direction is restricted, and as shown in FIG. 24 (d), the lower pedal 28 'is advanced to the second commodity storage passage 13b by the urging force of the lower pedal spring 28b'. Return to the no-standby posture. As a result, the second sold-out detection switch 27 is switched from the off state to the on state, and an on signal is given to the payout control unit 50.

  On the other hand, the upper pedal 29 'is urged by the upper pedal spring and moves backward as the stopper pin 34b' moves downward. As a result, the next product is allowed to move downward, and then the next product abuts against the lower pedal 28 'that has moved forward and is restricted from moving downward, as shown in FIG. The pedal 28 'shifts to the product-holding posture and returns to the standby state.

  In the drive unit 40, the cam portion 443 a then comes into contact with the proximal end portion 461 a of the first link lever 461 due to the rotation along the counterclockwise direction when viewed from the front of the output gear 443. In this case, the first link lever 461 is restricted from rotating around the central axis because the locking portion 461c is in contact with the left edge 471 of the right opening. Therefore, the locking portion 461c is elastically deformed so as to allow the proximal end portion 461a to approach the locking portion 461c, and does not hinder the movement of the cam portion 443a due to the rotation of the output gear 443.

  Then, when the cam portion 443a returns to the standby position by the rotation of the output gear 443, the pressing piece 443b presses the contact 45a of the carrier switch 45, and the carrier switch 45 switches from the OFF state to the ON state, and the ON signal Is given to the payout control unit 50. Thereafter, the payout control unit 50 stops driving the motor 43.

  FIG. 25 is a flowchart showing the processing contents of the first product carry-out process performed when the payout control unit 50 is given a first product carry-out command from the vending machine control unit 100. The first product carry-out process is performed at the same time as the first product carry-out operation by the product dispensing device 20 described above, but here, for convenience of explanation, it will be described separately from the carry-out operation.

  In the first product carry-out process, the payout control unit 50 drives the motor 43 to rotate forward (step S101), and from the carrier switch 45 until a preset time (for example, 1 to 2 seconds) preset in the memory 51 elapses. A wait state is waited for whether or not an ON signal is given (steps S102 and S103). That is, it is monitored whether or not the output gear 443 rotates once within the set time.

  As a result, when the carrier switch 45 is turned on within the set time (step S102: Yes, step S103: No), the payout control unit 50 stops the forward rotation drive of the motor 43 (step S104), and the procedure To end the current process.
