Description

  The present invention relates to a commodity dispensing apparatus, and more particularly, to a vending machine that sells commodities such as canned beverages and plastic bottled beverages, for example, commodity dispensing that appropriately unloads commodities stored in a commodity storage passage It relates to an apparatus.

  2. Description of the Related Art Conventionally, in a vending machine that sells products such as canned beverages and beverages with plastic bottles, for example, a commodity storage rack is provided in a commodity storage inside a main body cabinet which is a vending machine main body. The product storage rack has a product storage passage extending along the vertical direction, and a product unloading device disposed in the lower part of the product storage passage.

  The commodity carry-out device is configured to include 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, and appropriately moved to and from the product storage passage when the AC solenoid is energized.

  In such a product delivery device, in the standby state, the upper pedal is in a state of being retreated from the product storage passage, while the lower pedal is in a state of advancing and moving to the product storage passage. As a result, the lower pedal contacts the lowermost product stored in the product storage passage, and the downward movement of the product stored in the product storage passage is restricted.

  Then, when a product discharge command is given, in the product discharge device at the lower part of the product storage passage for storing the corresponding product, the upper pedal is advanced to the product storage passage via the link when the AC solenoid is energized. By moving and contacting the second lowest item, the item and items stored above the item are restricted from moving downward. Also, when the AC solenoid is energized, the lower pedal retracts from the product storage passage, the lowermost product is carried out only downward, and when the product slips through the lower pedal, the lower pedal is attached with a spring. Move forward to the product storage passage by force. Thereafter, when the AC solenoid is de-energized to be de-energized, the lower pedal advanced to the product storage passage is restricted from retreating movement, and the upper pedal is retracted from the product storage passage. Thus, the above-described standby state is restored.

  In the above-mentioned product storage rack, it is general that two product storage passages are adjacent to each other in the back and forth, and therefore the product unloading device applied to each product storage passage is assembled back to back and arranged in the product storage passage. It is configured to be installed. In such a product delivery device, an AC solenoid which is a driving source is required for each of the tied product delivery devices.

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

Patent No. 2749917 gazette

  However, in the product delivery device proposed in Patent Document 1, since the product delivery devices from which the AC solenoids have been removed are back-to-back with each other and the drive source and the cam are provided between them, the number of product delivery devices is increased. Although it is possible to reduce the number of drive sources, it has been difficult to separate the two product delivery devices assembled back-to-back as the component and use only one of them. That is, the product delivery apparatus proposed in Patent Document 1 can be applied to a product storage rack provided with an even number of product storage passages adjacent to each other in front and back, but for a product storage rack provided with an odd number of product storage passages It could not be used as an individual product delivery device. In addition, the product delivery device is provided with two types of product delivery devices having different widths corresponding to the types of product storage racks, that is, for products with relatively small maximum widths and products with relatively large maximum widths. It is general to mount a commodity unloading device having a width corresponding to the maximum width of the commodity stored in the rack on the commodity storage rack.

  SUMMARY OF THE INVENTION In view of the above situation, the present invention can provide a product dispensing apparatus capable of reducing manufacturing costs and flexibly responding to the number of product storage passages adjacent to each other. To aim.

In order to achieve the above object, the commodity delivery apparatus according to the present invention is applied to one commodity storage passage for accommodating input commodities along the vertical direction, and in the delivery standby state, the one commodity storage passage One of a commodity carrying-out device which carries out downward movement of the lowermost commodity stored in the one commodity storage passage while restricting the downward movement of the stored commodity, and driving it; The present invention is applied to the other product storage passage adjacent to the one product storage passage and storing the input products along the vertical direction, and in the unloading standby state, the product stored in the other product storage passage is directed downward. Control the movement toward the rear, while in the case of driving, the other goods delivery device for carrying out the lowermost goods stored in the other goods storage passage downward will be back-to-back with each other. In the commodity delivery device assembled in one of the above, the one commodity delivery device is disposed so as to be capable of rotating in the forward and reverse directions about the central axis of itself and the other commodity delivery device and one commodity delivery device. When an unloading command is given, while rotating from one of the predetermined standby positions toward one direction by the driving force from the drive source, when the unloading command is given to the other commodity unloading device, the standby is performed.

  In the base 21 ', a stopper pin (not shown), a pedal stopper pin 34b' and a stopper shaft 34c 'are provided between the bearing portion 24' and the second left bearing piece 23b '.

  The stopper pin is an axial member disposed along the substantially horizontal direction between the bearing portion 24 'and the second left bearing piece 23b'. The stopper pin is coupled to the pedal link 35 ', and can move along the vertical direction as the pedal link 35' moves in the vertical direction. The stopper pin is in contact with the recess 292 'of the upper pedal 29' at the initial position.

  The pedal stopper pin 34b 'is an axial member disposed along the substantially horizontal direction between the bearing portion 24' and the second left bearing piece 23b '. The pedal stopper pin 34b 'is coupled to the pedal link 35', and can move along the vertical direction as the pedal link 35 'moves in the vertical direction.

  The stopper shaft 34c 'is a shaft-like member disposed along the substantially horizontal direction between the bearing portion 24' and the second left bearing piece 23b ', and supports the rotation stopper 36' at the middle portion thereof. ing.

  The rotation stopper 36 'inserts the stopper shaft 34c' into the insertion hole at the base end, and can swing around the central axis of the stopper shaft 34c ', and the bearing 24' and the second left bearing piece It is arranged between 23b '.

  The rotation stopper 36 'has a pedal operation shaft 361' by passing a pedal operation shaft 361 '(see FIG. 4) through a through hole (not shown) at the tip end. 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 of the lower pedal 28'.

  A pedal operating spring (not shown) is interposed between the rotation stopper 36 'and the base 21'. The pedal operation spring always biases the rotation stopper 36 'toward the advancing movement with respect to the second product storage passage 13b.

  Such a rotation stopper 36 'is biased by the pedal operation spring in the direction of advancing and moving to the second product storage passage 13b, and the pedal stopper pin 34b is engaged with the recess 36b' of the rotation stopper 36 '. The movement in the backward movement direction is restricted by the fact that the '' enters and abuts against the pedal stopper pin 34 b ', and the initial position in the state of advancing and moving to the second product storage passage 13 b is set There is. Further, since the lower pedal 28 'is biased by the lower pedal spring 28b', both ends of the pedal operation shaft 361 'of the rotation stopper 36' are positioned at the fitting portion of the guide groove, and the lower pedal 28 'is An initial position is set at a position moved forward to the second product storage passage 13b.

  The pedal link 35 'is a long plate-like member extending along the vertical direction, and extends upward after being bent rearward at the top. At the upper portion of the pedal link 35 ', a contact piece 351' extending forward and then obliquely upward is provided, and a locking portion 352 'for locking the link spring 35a' is provided. It is provided. The link spring 35a 'is interposed between the pedal link 35' and the base 21 'and always biases the pedal link 35' downward.

  When the pedal link 35 'is biased downward by the link spring 35a' and disposed downward, the recess 292 'of the upper pedal 29' disposed at the retracted position abuts against the stopper pin. Moreover, the pivot stopper 36 'disposed at the advanced position abuts against the pedal stopper pin 34b', and the backward movement of the pivot stopper 36 'is restricted. Further, the pedal operating shaft 361 'of the rotation stopper 36' disposed at the advanced position is inserted into the insertion portion of the lower pedal 28 ', whereby the backward movement of the lower pedal 28' disposed at the advanced position is performed. It is regulated.

  On the other hand, in a state in which the pedal link 35 'is disposed upward against the biasing force of the link spring 35a', the stopper contact portion 293 'of the upper pedal 29' abuts on the stopper pin. The retrogressive movement of 29 'is restricted, and the upper pedal 29' is moved forward and arranged at the advanced position against the biasing force of the upper pedal spring.

  On the other hand, since the restriction of the retreating movement by the pedal stopper pin 34b 'is released from the pivoting stopper 36', the restriction of the retreating movement about the stopper shaft 34c 'is released. Here, a load of a product which is 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 retreating movement Is released, and the rotation stopper 36 'starts to move backward. When the backward movement of the rotation stopper 36 'is started, the lower pedal 28' moves backward about the first swing support shaft 28a 'because the pedal operation shaft 361' is disengaged from the insertion portion 283a of the lower pedal 28 '. The product is allowed to retract and resist against the elastic biasing force of the lower pedal spring 28b '.

  When the lower pedal 28 'is thus retracted, the base end of the lower pedal 28' is separated from the second sold-out contact portion 52 of the second sold-out link 50, resulting in the second sold-out link 50. Will be free. As a result, in the second sold-out detection switch 27, the contact 27a is biased by the spring to be in an upright position, thereby maintaining the off state. That is, also when the lower pedal 28 'moves backward, the second sold-out link 50 does not press the contact 27a of the second sold-out detection switch 27, as in the product-presenting standby posture.

  The commodity delivery device 20 is configured by assembling the first commodity carry-out device 20a and the second commodity carry-out device 20b having the configuration as described above back to back with the harness guide 25 as a guide member. And in this case, the first link lever 461 constituting the drive unit 40 has its tip end located in the lower area of the contact piece 351 of the pedal link 35, and the second link lever 462 has its tip end as a pedal It is located in the lower area of the contact piece 351 'of the link 35'.

  FIG. 20 is a block diagram showing a characteristic control system of the commodity delivery apparatus 20. As shown in FIG. As shown in FIG. 20, the commodity delivery apparatus 20 includes a delivery control unit 50. The payout control unit 50 centrally controls the operation of the commodity delivery apparatus 20 according to the program and data stored in the memory 51, and the input processing unit 501, the time measurement processing unit 502, the calculation processing unit 503, and the determination A processing unit 504, a motor drive processing unit 505, and an output processing unit 506 are provided.

  The input processing unit 501 inputs signals given from the first sold-out detection switch 26, the second sold-out detection switch 27, and the carrier switch 45. Further, the input processing unit 501 is to input a signal such as a command given from the vending machine control unit 100 that controls the vending operation of the vending machine.

  The time measurement processing unit 502 measures time in each process described later. The calculation processing unit 503 calculates an absolute value of a time difference of time measured by the time measurement processing unit 502 in each process described later.

  The determination processing unit 504 reads out various types of information stored in the memory 51 and compares the threshold included in the information with the absolute value of the time difference calculated by the calculation processing unit 503 to make a determination. Here, although various information is stored in the memory 51, in the present embodiment, first determination information, initial rotation time information and second determination information are stored. The first determination information includes a reference value that is a threshold in the assembly state determination process described later. This reference value is an experimentally determined threshold.

  The initial rotation information includes a first initial rotation time, which is an initial rotation operation time in one direction of the output gear 443 at the time of shipment of the vending machine on which the commodity delivery apparatus 20 is mounted, and an initial one in the other direction of the output gear 443. It includes the second initial rotation time which is the rotation operation time.

  The second determination information includes a first reference value and a second reference value as thresholds in the first deterioration determination process and the second deterioration determination process described later. The first reference value and the second reference value are experimentally determined thresholds.

  The motor drive processing unit 505 gives a drive command or a drive stop command to the motor 43 to drive or stop the motor 43. The output processing unit 506 is to perform various output processes, and in the present embodiment, outputs the determination result from the determination processing unit 504 to the vending machine control unit 100.

  In the goods delivery apparatus 20 comprised as mentioned above, it is as follows in a standby state. In the following, a product stored in the first product storage passage 13a will be referred to as a "first product", and a product stored in the second product storage passage 13b will be described as a "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 tip 461 b 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 tip 462 b of the second link lever 462 is It is at a position spaced downward from the contact piece 351 'of the pedal link 35'.

  Therefore, in the first product unloading device 20a, as shown in FIG. 5, the pedal link 35 is in the state of being disposed below. Further, the product is placed on the upper surface of the lower pedal 28 by the product inserted into the first product storage passage 13a, so that the lower pedal 28 is in the product-ready standby state, and the upper pedal 29 is the first product storage. It has a posture of retreating movement from the passage 13a (see (a) of FIG. 23). As described above, since the lower pedal 28 is in the product-ready standby posture, the first sold-out detection switch 26 is in the posture in which the contact 26a is erected and is in the OFF state.

  Further, in the second product carry-out device 20b, the pedal link 35 'is disposed at the lower side, the lower pedal 28' is in the product standby state, and the upper pedal 29 'is the second product storage passage. It is in a posture of retreating movement from 13b (see (a) in FIG. 24). As described above, since the lower pedal 28 'is in the commodity holding standby posture, the second sold-out detection switch 27 is in the posture in which the contact 27a is erected and is in the off state.

  In such a product delivery apparatus 20, when the delivery control unit 50 performs an input process of the delivery instruction for the first product given from the vending machine control unit 100, the motor drive processing unit 505 gives a drive instruction to the motor 43. The motor 43 is driven to rotate forward.

  As described above, when the motor 43 is driven to rotate forward, the output gear 443 to which the driving force of the motor 43 is transmitted through the worm gear 441 and the intermediate gear 442 rotates clockwise as viewed from the front.

  When the output gear 443 rotates clockwise as viewed from the front, the pressing piece 443 b of the output gear 443 disengages from the contact 45 a of the carrier switch 45. As a result, the contact 45a of the carrier switch 45 is released from the pressed state, switched from the on state to the off state, and gives an off signal to the payout control unit 50. Thus, the payout control unit 50 inputs the off signal from the carrier switch 45 through the input processing unit 501.

  When the cam portion 443a abuts on the base end portion 461a of the first link lever 461 from above due to the rotation of the output gear 443, the first link lever 461 rotates in a counterclockwise direction as viewed from the front. When the first link lever 461 rotates in the counterclockwise direction, the tip portion 461b moves upward. In this manner, the distal end portion 461b moves upward, and as shown in FIGS. 21 and 22, contacts the contact piece 351 of the pedal link 35 to resist the biasing 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 461a, the pedal link 35 can be held in a state of being 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 (i) including the portion in sliding contact with the cam portion 443a is the center axis of itself (the center axis of the first link shaft 42e) Adjustment is made so as to be substantially orthogonal to a plane (b) including the stop axis of the output gear 443.

  With the upward movement of the pedal link 35, the stopper pin 34a moves upward from the lower end portions of the stopper pin insertion holes 23b3 and 24c1, and the pedal stopper pin 34b moves from the lower end portions of the pedal stopper pin support grooves 23b4 and 24c2. Move upwards.

  At this time, since the stopper pin 34a moves upward while being in contact with the edge wall of the recess 292 of the upper pedal 29, as shown in FIG. 23 (b), the upper pedal 29 resists the biasing force of the upper pedal spring and initially Move forward from the position. The advancing 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, it abuts on the stopper abutting portion 293 to restrict the retreat of the upper pedal 29.

  Then, the upper pedal 29 moved forward is brought into contact with the second lowest first product (hereinafter also referred to as the next product), and regulates that the next product moves downward.

  On the other hand, since the load of the commodity coming in contact with the lower pedal 28 maintained at the advanced position is applied to the rotation stopper 36, the restriction of the retreating movement is released by the upward movement of the pedal stopper pin 34b. As a result, the rotation stopper 36 starts retreating movement.

  Thus, when the rotation stopper 36 starts retreating movement, the pedal operating shaft 361 comes out of the insertion portion 283a, and the lower pedal 28 starts retreating movement against the biasing force of the lower pedal spring 28b by the weight of the product. The pedal operation shaft 361 of the rotation stopper 36 which has come out of the insertion portion 283a moves along the first guide portion 283b toward a position where the first guide portion 283b and the second guide portion 283c intersect.

  After this, as shown in FIG. 23C, the lower pedal 28 retreats due to the weight of the lowest goods, and the downward movement of the lowest goods is permitted, and the lowest goods are unloaded downward. (See FIG. 8). The carried-out goods are guided to the goods discharge port 3c through the goods shooter 5 and are in a state where they can be taken out via the goods outlet 2a.

  Here, when the lowermost 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 by the elastic biasing force of the pedal operation spring. Move toward the exit 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 283 b and the second guide portion 283 c intersect is directed toward the insertion portion 283 a. Then, the lower pedal 28 and the rotation stopper 36 return to the advanced 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 biased by the link spring 35a to move downward.

  By the downward movement of the pedal link 35, the stopper pin 34a moves 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 end of the pedal stopper pin support grooves 23b4 and 24c2, the pedal stopper pin 34b abuts on the recess 36b on the back side of the rotation stopper 36 returned to the advanced position. Thus, movement in the backward movement direction is restricted, and as shown in (d) of FIG. 23, the lower pedal 28 moves forward with respect to the first product storage passage 13a by the biasing 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. Accordingly, the payout control unit 50 inputs the on signal from the first sold-out detection switch 26 through the input processing unit 501.

  On the other hand, the upper pedal 29 is biased by the upper pedal spring, and retreats along with the downward movement of the stopper pin 34a. As a result, the downward movement of the next product is permitted, and then the downward movement of the next product is restricted by coming into contact with the lower pedal 28 which has advanced, as shown in (a) of FIG. 28 shifts to a product presence standby posture and returns to the standby state.

  In the drive unit 40, the cam portion 443a comes in contact with the proximal end 462a of the second link lever 462 by the rotation of the output gear 443 in the clockwise direction as viewed from the front. In this case, the second link lever 462 is restricted in rotation around the central axis because the locking portion 462c is in contact with the right edge portion 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 the movement of the cam portion 443a due to the rotation of the output gear 443 is not inhibited.

  Then, when the cam portion 443a returns to the standby position by the rotation of the output gear 443 after that, the pressing piece 443b presses the contact 45a of the carrier switch 45 to switch the carrier switch 45 from the off state to the on state. Will be 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 disengaged from the base end 462a of the second link lever 462 and the second link lever 462 is returned to its original state by the locking portion 462c. To return. Thereafter, the payout control unit 50 gives a drive stop command to the motor 43 through the motor drive processing unit 505 to stop the drive of the motor 43.

  On the other hand, in the commodity delivery apparatus 20, the motor 43 is reversely driven when the delivery control unit 50 inputs and processes the delivery instruction of the second commodity given from the vending machine control unit 100.

  When the motor 43 is reversely driven in this manner, 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 a counterclockwise direction as viewed from the front.

  When the output gear 443 rotates counterclockwise as viewed from the front, the pressing piece 443 b of the output gear 443 disengages from the contact 45 a of the carrier switch 45. As a result, the contact 45a of the carrier switch 45 is released from the pressed state, switched from the on state to the off state, and gives an off signal to the payout control unit 50. Thus, the payout control unit 50 inputs the off signal from the carrier switch 45 through the input processing unit 501.

  When the cam portion 443a abuts on 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 clockwise as viewed from the front. When the second link lever 462 rotates in the clockwise direction, the tip end portion 462b moves upward. In this manner, the tip end portion 462b moves upward to abut against the contact piece 351 'of the pedal link 35', and the pedal link 35 'is directed upward against the biasing force of the link spring 35a'. Thus, while the cam portion 443a is in sliding contact with the base end portion 462a, the pedal link 35 'can be maintained in the state of being moved upward by a predetermined distance.

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

  Along with the upward movement of the pedal link 35 ', the stopper pin moves upward, and the pedal stopper pin 34b' also moves upward.

  At this time, since the stopper pin moves upward while being in contact with the edge wall of the recess 292 'of the upper pedal 29', the upper pedal 29 'resists the biasing force of the upper pedal spring as shown in FIG. And move forward from the initial position. The advancing movement of the upper pedal 29 'is performed by the upward movement of the stopper pin. Then, when the stopper pin reaches the upper end of the stopper pin insertion hole, the stopper pin abuts on the stopper abutting portion 293 'to restrict the retraction of the upper pedal 29'.

  Then, the upper pedal 29 'which has advanced and moved in contact with the second product from the bottom (hereinafter, also referred to as a next product) regulates the movement of the next product downward.

  On the other hand, since the load of the commodity coming in contact with the lower pedal 28 'maintained at the advanced position is applied to the rotation stopper 36', the restriction movement of the backward movement is caused by the upward movement of the pedal stopper pin 34b '. By being released, the rotation stopper 36 'starts to move backward.

  Thus, when the rotation stopper 36 'starts retreating movement, the pedal operation shaft 361' comes out of the insertion portion, and the lower pedal 28 'starts retreating movement against the biasing force of the lower pedal spring 28b' by its own weight. Do. The pedal operation shaft 361 'of the rotation stopper 36' removed from the insertion portion moves along the first guide portion toward a position where the first guide portion and the second guide portion intersect.

  After this, as shown in FIG. 24C, the lower pedal 28 'is retreated due to the weight of the lowest goods, and the downward movement of the lowest goods is permitted, and the lowest goods are downward. It is carried out. The carried-out goods are guided to the goods discharge port 3c through the goods shooter 5 and are in a state where they can be taken out via the goods outlet 2a.

  Here, when the lowermost 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 advanced 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 is moved toward the insertion portion. 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 biased by the link spring 35a' to move downward.

  By 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' abuts against the recess 36b 'on the back side of the rotation stopper 36' returned to the advanced position. This restricts the movement in the backward movement direction, and as shown in (d) of FIG. 24, the lower pedal 28 'is moved to the second product storage passage 13b by the biasing force of the lower pedal spring 28b'.
