Next, the operation of driving the link mechanism 54 of the first payout mechanism 501 in the merchandise unloading device 5 by the motor drive unit 70A to pay out the merchandise will be described with reference to FIGS. 32 to 34. 32 to 34 show the main parts of the first payout mechanism in the product unloading device 5, FIG. 32 is an operation explanatory view before the product loading, FIG. 33 is an operation explanatory diagram in the sales standby state, and FIG. 34 is an operation at the time of sale. It is explanatory drawing.

As shown in FIG. 32, the pedal member 52 of the first payout mechanism 501 protrudes into the product storage passage 43 before the product is loaded, and the stopper member 53 is retracted from the product storage passage 43. In this case, the cam protrusion 7151 of the output gear 715 of the motor drive unit 70A is located at the frontmost position (see (a) of FIG. 27). Further, the pressing piece for the carrier switch 716 provided on the back surface of the output gear 715 is located at the foremost position, and the carrier switch 716 is in the ON state. As a result, the motor 711 is stopped, and the tip end portion 718b of the link lever 718 is located at a position separated rearward from the engaging piece 544 provided at the front end of the link member 541a (see also FIG. 17). Therefore, the link member 541a is in a retracted state due to the urging force of the return spring 540. Further, the pedal member 52 is in a protruding position opened to the maximum opening degree in the product storage passage 43 by the urging force of the torsion coil spring (not shown). The operating range of the pedal member 52 is restricted by the cooperation with the rear link pin 55 inserted into the deformed hole 523 provided in the bearing portion 522 of the pedal member 52, and the pedal member 52 does not open more than the maximum opening degree. .. As described above, when the pedal member 52 is opened to the maximum opening degree, the bearing portion 522 of the pedal member 52 is located on the rear end side of the bearing portions 515 and 515, and the first sold-out detection mechanism 81 is accompanied by this. The detection lever 801a of the above slides to the rearmost position, and the sold-out detection switch 802a is in the ON state. On the other hand, the stopper member 53 receives the front link pin 56 that has moved to the retracted position in the concave sliding groove 533a formed in the stopper wall 533 and is maintained in the retracted position retracted from the product storage passage 43.

In such a standby state, the first loaded product G comes into contact with the holding portion 521 of the pedal member 52 which is opened to the maximum opening degree and is in the protruding position. When the product G comes into contact with the product G, the pedal member 52 rotates toward the retracted position. Due to this rotation, the lock groove portion 523a of the deformed hole 523 in the bearing portion 522 of the pedal member 52 comes into contact with the rear link pin 55 that has moved to the retracted position, and the pedal member 52 is locked to the protruding position protruding into the product storage passage 43. , The product G held by the pedal member 52 is the product with the highest sales order (sales product G1) (see FIG. 33). In this way, when the pedal member 52 is rotated so as to protrude from the maximum opening degree to the product storage passage 43 with an opening degree smaller than the maximum opening degree, the detection lever of the first sold-out detection mechanism 81 When the 801a (contact portions 8013, 8013) are pressed against the bearing portion 522 of the pedal member 52, the pedal member 52 advances and the sold-out detection switch 802a is turned off. The next loaded product is stacked on the sold product G1 held by the pedal member 52 to become the next sold product G2, and the subsequently loaded products are sequentially stacked on the next sold product G2.

The product G housed in the product storage rack 4 in this way is cooled or heated by the cooling / heating unit 7 and stored in a cold or hot state suitable for sale, and is in a sellable state (sales standby state). In such a sales standby state, when a sales command is given to the motor drive unit 70A based on the operation of the product selection switch, the motor 711 built in the motor drive unit 70A is reversely driven and is driven in reverse through the gear transmission mechanism 714. The output gear 715 rotates in the clockwise direction in FIG. 29 (a). When the output gear 715 rotates, the pressing piece provided on the back surface of the output gear 715 separates from the contact of the carrier switch 716, the carrier switch 716 is turned off, and then the carrier switch 716 is turned on (that is,). The motor 711 is reversely driven (the period until the output gear 715 makes one rotation). When the cam protrusion 7151 comes into contact with the base end portion 718a of the link lever 718 from the front due to the rotation of the output gear 715, the link lever 718 rotates in the counterclockwise direction in FIG. 29 (a). By rotating the link lever 718 in the counterclockwise direction, the tip portion 718b abuts on the contact piece 5411a provided on the engaging piece 5411 of the link member 541a, and the link member 541a becomes the urging force of the return spring 540. Move forward against it. Then, while the cam protrusion 7151 is in sliding contact with the base end portion 718a of the link lever 718 (see (b) of FIG. 29), the link member 541a is held in the advanced state.

As the link member 541a advances, the rear link pin 55 supported by the link member 541a also advances and separates from the lock groove portion 523a of the deformed hole 523 of the pedal member 52, so that the rear link pin 55 locks the rear link pin 55 to a protruding position. The locked pedal member 52 is unlocked. As a result, the pedal member 52 moves toward the retracted position against the urging force of the torsion coil spring (not shown) due to the load of the product (see FIG. 32). By moving the pedal member 52 to the retracted position, the product G1 for sale passes through the pedal member 52 and is carried out to the rear. When the product G1 passes through the pedal member 52, the pedal member 52 returns to the protruding position by the urging force of the torsion coil spring (not shown).

On the other hand, the stopper member 53, which receives the front link pin 56 held by the link member 541a in the standby state for sale in the concave sliding groove 533a and is maintained in the retracted position, moves forward together with the link member 541a. Is pushed out toward the protruding position by coming into contact with the wall surface of the sliding groove 533a (see FIG. 34). Then, the front link pin 56 advances to a position of the stopper member 53 facing the stopper surface 533b of the stopper wall 533, so that the front link pin 56 comes into contact with the stopper surface 533b and the movement of the stopper member 53 to the retracted position is restricted. Then, the stopper member 53 that has moved to the protruding position abuts and holds the next sale product G2 that moves backward when the sale product G1 is carried out, and restricts the next sale product G2 from moving backward. To do.

The operation of moving the stopper member 53 from the retracted position to the protruding position to hold the next sold product G2 while retracting the pedal member 52 to the retracted position and paying out the sold product G1 is performed by the cam protrusion 7151 of the output gear 715. It is executed during a predetermined time during sliding contact with the base end portion 718a of the link lever 718.

Then, when the contact between the cam protrusion 7151 and the base end portion 718a of the link lever 718 is released by the rotation of the output gear 715, the link member 541a retracts due to the urging force of the return spring 540. Due to the retreat of the link member 541a, the front link pin 56 supported by the link member 541a enters the sliding groove 533a from the stopper surface 533b of the stopper member 53 and moves the stopper member 53 toward the retracted position. By moving the stopper member 53 to the retracted position, the next-sale product G2 held by the stopper member 53 moves rearward and comes into contact with the pedal member 52 opened to the maximum opening degree. After that, the lock groove portion 523a of the deformed hole 523 in the bearing portion 522 of the pedal member 52 comes into contact with the rear link pin 55 that has moved to the retracted position, and the pedal member 52 is locked to the protruding position protruding into the product storage passage 43. The next sale product G2 is held as a sale product. Then, when the cam protrusion 7151 returns to the standby position due to the rotation of the output gear 715, the contactor of the carrier switch 716 is pressed by the pressing piece, and the carrier switch 716 is turned on. As a result, the drive of the motor 711 is stopped and the state returns to the sales standby state.

The cam protrusion 7151 of the output gear 715 returns to the standby position after the contact between the cam protrusion 7151 and the base end portion 718a of the link lever 718 is released by the rotation of the output gear 715 in the clockwise direction. On the way, it comes into contact with the base end portion 717a of the other link lever 717, but the locking piece 717c made of an elastic member is elastically deformed to allow the link lever 717 to rotate, so that the cam protrusion 7151 is prevented from moving. It returns to the return position without any problem. The link lever 717 returns to the standby posture shown in FIG. 29 (a) by the action of the locking piece 717c when the cam protrusion 7151 passes through.

The operation of driving the link mechanism 54 (link member 54b) of the second payout mechanism 502 in the product carry-out device 5 to pay out the goods is performed by the motor 711 built in the motor drive unit 70B (see (a) of FIG. 29). Is carried out by reverse driving. In this case, similarly to the operation of the motor drive unit 70A, the output gear 715 is rotated in the clockwise direction by the reverse drive of the motor 711, and the cam protrusion 7151 provided on the back surface of the output gear 715 and the link lever 718 cooperate. The link member 541b of the second payout mechanism 502 is operated by the operation. As a result, the pedal member 52 and the stopper member 53 of the second payout mechanism 502 are alternately infested in the product storage passage 43 to carry out the sales product G1 and hold the next sales product G2 as a sales product on the pedal member 52. To return to the standby state.

Next, FIG. 39 shows the product G (for example, a square PET bottle) by adjusting the distance between the product unloading device 5 and the passage surface of the product storage passage 43 by the attachment 20 laid on the product storage shelf 10. It shows the case where it is stored. FIG. 39 shows an example in which a cylindrical can product G is stored in the uppermost product storage shelf 10 and a square PET bottle G is stored in the second product storage shelf 10 from the top. The operation of adjusting the distance between the attachment 20 laid in close contact with the plate surface (passage surface) of the product storage shelf 10 and the product unloading device 5 is as described above together with FIGS. 10 to 14 and the like. Duplicate explanations will be omitted.

Further, assuming that the product storage passage 43 accommodating the square PET bottle G is the product column C4 shown in FIG. 35, the operation of the product unloading device 5 is the product unloading device 5 in the product column C4 of FIG. 35 described above. It is the same as the operation of. In this case, the second attachment 22 constituting the attachment 20 is set in a state where the passage surface forming portion 220 is inclined to an inclination angle larger than the inclination angle of the passage surface forming portion 210 of the first attachment 21, and thus is sold. The product G1 (square PET bottle on the second attachment 22 having a large inclination angle) can be reliably slid and dropped into the product drop passage 46.

When the product storage passage 43 (product column) containing the square PET bottle G is used as the product column for a cylindrical can product, the attachment 20 is operated to make close contact with the plate surface (passage surface) of the product storage shelf 10. And return it to the laid state. In this way, it is not necessary to attach / detach the attachment 20 from the product storage shelf 10.

By the way, in this type of product storage rack (slan truck) 4, the axis of the product is the product while the product is rolling or sliding in the product storage passage 43 when the product is loaded (when the vending machine is installed or when the product is replaced). There is a risk of causing product jams such that the product changes its posture so as to be inclined from the direction perpendicular to the traveling direction (front-back direction) of the product and stops in the middle of the product storage passage 43. Further, the product first loaded in the product storage passage 43 (when the vending machine is installed or when the product is replaced) is held by the pedal member 52 of the product unloading device 5 arranged at the product carry-out port 45 of the product storage passage 43. However, when the first loaded product G (sold product G1) is held by the pedal member 52 in a state of changing its posture and tilting, the product storage of the stopper member 53 that holds the next sold product G2 is performed. The protrusion to the passage 43 may be hindered by the product G1 for sale and cause a product jam that locks the product. When product clogging occurs in this way, in this embodiment, the product storage shelf 10 is composed of a front side shelf member 11 and a rear side shelf member 12 divided in the front-rear direction, and the rear side shelf member 12 is a pair of left and right racks. Since the front side shelf members 11 are detachably arranged on the pair of left and right rack side plates 41 and 41 while being erected on the side plates 41 and 41, the product storage rack 4 is attached to the inside of the refrigerator as follows. It is possible to eliminate product clogging.

That is, when the product G is on the front shelf member 11, the product G is inserted into the product storage passage 43 while visually observing the product G stored in the product storage passage 43 from the front of the product storage passage 43. Take out one by one. When the product jam is not cleared even if the product G on the front shelf member 11 is taken out (when the product jam occurs in the area of the rear shelf member 12), the front shelf member 11 is moved to the front as described above. The side shelf member 11 is removed from the rack side plates 41, 41 in the reverse order of the mounting procedure on the rack side plates 41, 41. In this case, the rear engaging claws 2111b (2211b) of the pair of front and rear engaging claws 4211b, 4211b (2211b, 2211b) provided on the partition member 42 before the front side shelf member 11 is removed are used as the rear side shelf member. The partition member 42 is removed from the product storage rack 4 together with the front side shelf member 11 by pulling it out from the setting grooves 127R and 127L (127M) formed in 12. As described above, by removing the front side shelf member 11, it is possible to insert a hand to the position of the rear side shelf member 12. After that, the product G on the rear shelf member 12 is taken out to clear the product clogging. In this way, since the front side shelf member 11 can be removed to clear the product clogging, the product storage rack 4 stored and installed in the vending machine can be removed and taken out to the outside of the vending machine to clear the product clogging. It is possible to avoid the complicated work of solving the problem.

As described above, according to the product unloading device of the vending machine according to this embodiment, the product storage shelf 10 is arranged so as to be inclined so that the product unloading port 45 is lower than the product input port 44.

Therefore, when selling the product S stored in the product storage passage 43 corresponding to the four rows of short size products S, the DC motors 711 of the two motor drive units 70A and 70B are individually rotated in the normal direction. Alternatively, by reversing, the short-sized product S stored in each product storage passage 43 can be individually and stably carried out, while the product stored in the product storage passage 43 corresponding to the two rows of long-sized products L. When selling L, the DC motors 711 of the two motor drive units 70A and 70B are synchronized to rotate forward or reverse, respectively, to stabilize the long-sized product L stored in each product storage passage 43 individually. The product can be carried out, and the number of drive means can be reduced while making it possible to sell different types of products having different lengths on one product storage shelf 43.

In the above-described embodiment, an example of selling products stored in four rows of product columns defined on the product storage shelf 10 by using two motor drive units 70A and 70B has been described. When a product column having only two rows on the left and right is defined on the storage shelf 10, one drive means (for example, a motor drive unit 70A) is used, and the product storage passage 43 is provided via the link mechanism 54 and the link mechanism 54.
