Is shown in. 19A and 19B, the substrate 51, the adjusting members 81 and 82, and the movable bearing member 60 are extracted and shown.

FIG. 19A shows a state in which the adjusting member 81 is pressed by the partition member 42 set on the product storage rack 10 and moved rearward. In this case, when the adjusting member 81 is pressed by the partition member 42 and moves rearward, the pressing piece 813 provided at the rear end slides on the L-shaped sliding piece 610a provided on the bearing portion 61 of the movable bearing member 60. The movable bearing member 60 is moved to the right side of the opening flanges 516 and 516 (see FIG. 6A) of the opening flanges 516 and 516 (see FIG. 6A) formed on both sides of the rear end side opening 513 of the substrate 51. ing. The position where the movable bearing member 60 moves to the right side opening flange 516 side of the opening flanges 516 and 516 (see FIG. 6A) is also referred to as an initial position.

As shown in (a) of FIG. 19, when the movable bearing member 60 is moved to the initial position, a pressing piece 823 is provided on the bearing portion 61 of the movable bearing member 60 at the rear end of the adjusting member 82. It is located at a position overlapping the character-shaped sliding piece 610b in the front-rear direction. In this state, when the adjusting member 82 is pressed by the partition member 42 and moves rearward, the pressing piece 823 provided at the rear end of the adjusting member 82 moves to the bearing portion 61 of the movable bearing member 60, as shown in FIG. The movable bearing member 60 is slid on the provided L-shaped sliding piece 610b to move the movable bearing member 60 leftward from the initial position by a predetermined distance L. Here, the adjusting member 81 moving rearward is adjusted by the L-shaped sliding piece 610a provided in the bearing portion 61 while the movable bearing member 60 is moving leftward from the initial position by a predetermined distance L. The member 81 comes into contact with a pressing piece 813 provided at the rear end of the member 81 and is pushed forward. As a result, the adjusting member 81 moves forward and returns to the standby position. Similarly to the adjusting member 81, the adjusting member 82 that has moved rearward also moves forward by the movement of the movable bearing member 60 to the initial position and returns to the standby position. Therefore, since it is not necessary to provide a spring for returning to the adjusting members 81 and 82, the number of parts can be reduced.

As shown in FIG. 20, the sold-out detection mechanism 91 of the payout mechanism 501 of the product unloading device 5A includes a detection lever 901 and a sold-out detection switch 902. The detection lever 901 includes a pair of left and right locking pieces 9012 bent downward from both left and right ends of a flat plate-shaped base end portion 9011, and a pair of left and right curled shapes formed by projecting rearward from the rear end of the base end portion 9011. It is made of a thin steel plate having an abutting part 9013 and a hook-shaped actuating piece 9014 at the tip extending forward from the base end 9011. The pair of left and right locking pieces 9012 are provided with bosses 9012a that are formed by extrusion in the directions opposite to each other. The sold-out detection switch 902 is made up of a micro switch locked and fixed to the substrate 51.

The detection lever 901 is mounted on bearings 514 and 514 provided on the rear end side of the substrate 51. In this case, the pair of left and right locking pieces 9012 of the detection lever 901 are arranged so as to cover the bearing portions 514 and 514 with the base end portion 9011 in a manner of straddling the bearing portions 514 and 514. At that time, the bosses 9012a and 9012a provided on the pair of left and right locking pieces 9012 and 9012 are fitted into the elongated holes 5144 and 5144 (see FIG. 6B) extending in the front-rear direction provided on the bearing portions 514 and 514, and the left and right pairs are formed. Of the four bearing portions 522 of the pedal member 52 in which the curled contact portions 9013 and 9013 are assembled to the bearing portions 514 and 514, the front of the bearing portions 522 at the left and right ends (see FIGS. 8 and 21A). It is configured to be positioned and located on the rotation locus. The diameters of the bosses 9012a and 9012a are smaller than the groove widths of the long holes 5144 and 5144, and the bosses 9012a and 9012a are loosely fitted in the long holes 5144 and 5144. As a result, the detection lever 901 can slide in the front-rear direction along the elongated hole 5144 in which the boss 9012a is loosely fitted. The operation piece 9014 of the detection lever 901 is configured to operate the contact 902a of the sold-out detection switch 902 fixed to the substrate 51 by sliding the detection lever 901 in the front-rear direction.

The pair of left and right curled contact portions 9013 and 9013 of the detection lever 901 are located in front of the bearing portions 522 (see FIGS. 8 and 21A) at the left and right ends of the pedal member 52 assembled to the bearing portions 514 and 514. It is located on the rotation locus and is configured so that the bearing portion 522 comes into contact with the rotation of the pedal member 52. In this case, although illustration is omitted, a pair of left and right curled contact portions 9013, 9013 of the detection lever 901 are urged by a biasing spring that biases the detection lever 901 rearward so that the left and right bearing portions of the pedal member 52 are supported. It always contacts 522. Therefore, the detection lever 901 slides in the front-rear direction in response to the protrusion of the pedal member 52 into the product storage passage 43 and the retreat movement from the product storage passage 43.

The sold-out detection switch 902 is configured to detect, via the detection lever 901, the state in which the pedal member 52 protrudes into the product storage passage 43 to the maximum opening degree. That is, the pedal member 52 is constantly urged toward the protruding position by the elastic urging force of the torsion coil spring 520 (not shown), and the maximum opening degree is obtained when the pedal member 52 protrudes into the product storage passage 43 without holding the product. When a product comes into contact with the pedal member 52 protruding to the maximum opening degree, the product slightly rotates in the direction of retracting from the product storage passage 43, and then the lock groove portion 523a of the deformed hole 523 in the bearing portion 522 of the pedal member 52 becomes The pedal member 52 is locked so that it abuts the rear link pin 55 retracted to the retracted position so as to project into the product storage passage 43, and the opening degree of the pedal member 52 in the locked state is smaller than the maximum opening degree. ing. In this way, the bearing portion 522 of the pedal member 52 is located on the rear end side of the bearing portions 514 and 514 with the pedal member 52 protruding to the maximum opening degree in the product storage passage 43, and accordingly, the detection lever It is detected that 901 slides to the rearmost position, the sold product contacts the pedal member 52 protruding to the maximum opening degree, and the pedal member 52 is slightly rotated in the direction of retracting from the product storage passage 43 and then locked. The lever 901 slides forward by a predetermined dimension. In the sold-out detection switch 902, when the detection lever 901 slides to the rearmost, the contact piece 902a of the sold-out detection switch 902 is pressed by the operating piece 9014 of the detection lever 901 to turn on, and the detection lever 901 moves to the rearmost. When a predetermined size is moved forward from the state in which the contact lever 901 has been moved to, the contact piece 902a of the sold-out detection switch 902 is released from being pressed by the operating piece 9014 of the detection lever 901 to be turned off. As described above, the sold-out detection switch 902 is configured to detect the state in which the pedal member 52 is projected to the maximum opening degree in the product storage passage 43 via the detection lever 901. In the control unit that processes the signal from the sold-out detection switch 902, when the ON signal from the sold-out detection switch 902 continues for a predetermined time, a process of determining "sold out" is performed.

The sold-out detection mechanism 92 corresponding to the payout mechanism 502 of the product discharge device 5A also includes a detection lever 901 and a sold-out detection switch 902. In this case, the detection lever 901 extends to the bearing portions 515 and 515 provided on the rear end side of the substrate 51, and the bosses 9012a provided to the pair of left and right locking pieces 9012 extend in the front-rear direction provided on the bearing portions 515 and 515. It is fitted in the long holes 5154 and 5154 and is mounted so as to be slidable in the front-rear direction. The pair of left and right curled contact portions 9013 provided at the rear end of the detection lever 901 and the bearing portions at the left and right ends of the four bearing portions 522 of the pedal member 52 assembled to the bearing portions 515 and 515. 522 (see FIG. 8 and FIG. 21A) and the operation of the sold-out detection switch 902 by the operation piece 9014 of the detection lever 901 are performed by the curled contact portion 9013 of the detection lever 901 of the sold-out detection mechanism 91 described above. The relationship with the left and right bearing portions 522 of the four bearing portions 522 of the pedal member 52 assembled to the bearing portions 514 and 514 and the operation of the sold-out detection switch 902 by the operating piece 9014 of the detection lever 901 are the same. Therefore, I will omit duplicate explanations here.

The sold-out detection mechanisms 93 and 94 corresponding to the payout mechanisms 503 and 504 of the product delivery device 5B also include detection levers 901 and 901 and sold-out detection switches 902 and 902. In this case, the sold-out detection mechanism 90B differs from the sold-out detection mechanism 93 described above in that the detection levers 901 and 901 respectively corresponding to the payout mechanisms 503 and 504 are attached to the movable bearing member 60 and the sold-out detection mechanism 90B is installed. Since they are the same except that they move in the left-right direction along with the movement in the left-right direction, the same parts are designated by the same reference numerals.

The detection lever 901 of the sold-out detection mechanism 93 is attached to the bearing portion 61 of the movable bearing member 60 provided on the substrate 51 so as to be movable in the left-right direction. In this case, the pair of left and right locking pieces 9012 and 112 of the detection lever 901 of the sold-out detection mechanism 93 straddles the ceiling wall 611 of the box-shaped bearing portion 61 so that the base end portion 9011 is attached to the ceiling of the box-shaped bearing portion 61. It is arranged so as to cover the wall 611. At that time, the bosses 9012a and 9012a provided on the pair of left and right locking pieces 9012 and 9012 are fitted into the longitudinal holes 618 and 618 (see FIG. 7) provided on the left and right side walls 612 and 613 of the bearing portion 61 and extending in the front-rear direction.

As described above, the bearing portion 522 (see FIG. 12) of the pedal member 52 assembled to the bearing portion 61 is configured to enter, and the pair of left and right curled contact portions 9013 is the bearing. By being immersed in the openings 611a and 611a of the portion 61, it is possible to contact the bearing portion 522 of the pedal member 52. In this case, although illustration is omitted, a pair of left and right curled contact portions 9013 of the detection lever 901 always contact the bearing portion 522 of the pedal member 52 by an urging spring that urges the detection lever 901 rearward. ing. Therefore, the detection lever 901 slides in the front-rear direction in response to the protrusion of the pedal member 52 into the product storage passage 43 and the withdrawal from the product storage passage 43. The relationship between the pair of left and right curled contact portions 9013 provided at the rear end of the detection lever 901 and the bearing portion 522 (see FIG. 12) of the pedal member 52 assembled to the bearing portion 61 is described above. The same relationship as the curl-shaped contact portion 9013 of the detection lever 901 of the cut detection mechanism 91 and the left and right bearing portions 522 of the four bearing portions 522 of the pedal member 52 assembled to the bearing portions 514 and 514. Is. Then, regarding the operation of the sold-out detection switch 902 by the operation piece 9014 of the detection lever 901, the detection lever 901 of the sold-out detection mechanism 93 is attached to the movable bearing member 60 and the movable bearing member 60 moves in the left-right direction. The operation is the same as the operation of the sold-out detection switch 902 by the operation piece 9014 of the detection lever 901 of the sold-out detection mechanism 91 described above except that the sold-out detection mechanism 91 is moved in the left-right direction.

The sold-out detection mechanism 94 corresponding to the payout mechanism 504 of the product discharge device 5B also includes a detection lever 901 and a sold-out detection switch 902. In this case, the detection lever 901 of the sold-out detection mechanism 94 is provided on the bearing portion 62 of the movable bearing member 60 that is provided on the substrate 51 so as to be movable in the left-right direction, and the bosses 9012a provided on the pair of left and right locking pieces 9012, 9012. 9012a is fitted in elongated holes 628, 628 provided in the left and right side walls 622, 623 and extending in the front-rear direction, and is attached in a manner slidable in the front-rear direction. In this case, a pair of left and right curled contact portions 9013 provided at the rear end of the detection lever 901 have openings 621a, 621a at both left and right sides provided at the rear end side of the ceiling wall 621 of the bearing 62 (see FIG. 7). Immerse yourself in. The left and right openings 621a and 621a provided on the rear end side of the ceiling wall 621 of the bearing portion 62 where the pair of left and right curled contact portions 9013 of the detection lever 901 are recessed are attached to the bearing portion 62. The bearing portions 522 (see FIG. 8) at the left and right ends of the pedal member 52 are configured to enter, and are attached to the pair of left and right curled contact portions 9013 and the bearing portion 62 of the detection lever 901. The relationship between the pedal member 52 and the bearing portion 522 and the operation of the sold-out detection switch 902 by the operating piece 9014 of the detection lever 901 are performed by the curl-shaped contact portion 9013 and the bearing portion of the detection lever 901 of the sold-out detection mechanism 93 described above. This is the same as the relationship with the left and right bearing portions 522 of the four bearing portions 522 of the pedal member 52 assembled to 514 and 514 and the operation of the sold-out detection switch 902 by the operating piece 9014 of the detection lever 901. Here, duplicate description will be omitted.

Here, an operation of driving the link mechanism 54 of the dispensing mechanism 501 in the product unloading device 5A by the motor drive unit 70A to dispense the product will be described.

As shown in FIG. 21A, the pedal member 52 of the dispensing mechanism 501 projects 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 projection 7151 of the output gear 715 of the motor drive unit 70A is located at the frontmost position (see FIG. 16A). Further, the pressing piece for the carrier switch 716 provided on the back surface of the output gear 715 is located at the most front, and the carrier switch 716 is in the ON state. As a result, the motor 711 is stopped, and the distal end portion 718b of the link lever 718 is located rearwardly from the engaging piece 544 provided at the front end of the link member 541a (see also FIG. 5D). Therefore, the link member 541a is in a retracted state by the biasing force of the return spring 540. Further, the pedal member 52 is in a projecting position which is opened to the maximum opening degree in the product storage passage 43 by the urging force of a torsion coil spring (not shown). The operation range of the pedal member 52 is restricted by the cooperation with the rear link pin 55 inserted through the deformed hole 523 provided in the bearing portion 522 of the pedal member 52, and the pedal member 52 does not open beyond 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 514 and 514, and accordingly, the sold-out detection mechanism 91 detects The lever 901 slides to the rearmost position and the sold-out detection switch 902 is in the ON state. On the other hand, the stopper member 53 is maintained at the retracted position in which the recessed sliding groove 533a formed in the stopper wall 533 receives the front link pin 56 moved to the retracted position and retracts from the product storage passage 43.

In such a standby state, the first loaded product G opens to the maximum opening degree and comes into contact with the holding portion 521 of the pedal member 52 at the protruding position. When the product G contacts, the pedal member 52 rotates toward the retracted position. By 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 at the protruding position protruding into the product storage passage 43. The product G held by the pedal member 52 becomes the first product in the sales order (sales product G1) (see FIG. 21B). In this way, when the pedal member 52 is rotated so as to be locked in a state of protruding from the maximum opening degree to the product storage passage 43 at an opening degree smaller than the maximum opening degree, the detection lever 901 of the sold-out detection mechanism 91 is moved. The sold-out detection switch 902 is turned off by being pushed forward by being pressed by the bearing portion 522 of the pedal member 52. The next loaded product is stacked on the sales product G1 held by the pedal member 52 to become the next sales product G2, and the products subsequently loaded are sequentially stacked on the next sales product G2.

In this way, the products G stored in the product storage rack 4 are cooled or heated by the cooling/heating unit 7 and stored in a cold or hot state suitable for sale and put into a state ready for sale (standby state for sale). 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 incorporated in the motor drive unit 70A is reversely driven and the gear transmission mechanism 714 is used. The output gear 715 rotates in the clockwise direction in FIG. When the output gear 715 rotates, the pressing piece provided on the back surface of the output gear 715 is disengaged 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 driven in the reverse direction 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. By the counterclockwise rotation of the link lever 718, the tip portion 718b abuts the engaging piece 544 of the link member 541a to move the link member 541a forward against the biasing force of the return spring 540. Then, while the cam projection 7151 is in sliding contact with the base end portion 718a of the link lever 718 (see FIG. 16B), the link member 541a is held in the advanced state.

The locked pedal member 52 is released. As a result, the pedal member 52 moves toward the retracted position against the biasing force of the torsion coil spring (not shown) by the load of the product (see FIG. 21C). By moving the pedal member 52 to the retracted position, the sale product G1 slips through the pedal member 52 and is carried out rearward. When the sold product G1 slips through the pedal member 52, the pedal member 52 returns to the projecting position by the urging force of a torsion coil spring (not shown).

On the other hand, the stopper member 53 that receives the front link pin 56 held by the link member 541a in the sale standby state in the recessed sliding groove 533a and is maintained at the retracted position is the front link pin 56 that advances together with the link member 541a. Is abutted against the wall surface of the sliding groove 533a, and is pushed out toward the protruding position (see FIG. 21C). Then, as the front link pin 56 advances to a position facing the stopper surface 533b of the stopper wall 533 of the stopper member 53, the front link pin 56 comes into contact with the stopper surface 533b to restrict the movement of the stopper member 53 to the retracted position. Then, the stopper member 53 that has moved to the projecting position abuts and holds the next-sale product G2 that moves backward when the sale-product G1 is unloaded, and restricts the next-sale product G2 from moving rearward. To do.

The cam projection 7151 of the output gear 715 is operated to move the stopper member 53 from the retracted position to the projecting position and hold the next sold product G2 while the pedal member 52 is retracted to the retracted position to dispense the sold product G1. It is executed during a predetermined time of sliding contact with the base end portion 718a of the link lever 718.

Then, when the contact between the cam projection 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. By retracting 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 the movement of 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 which is 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 at the protruding position protruding into the product storage passage 43. The next sale item G2 is held as a sale item. Then, when the cam projection 7151 returns to the standby position by the rotation of the output gear 715, the contact piece of the carrier switch 716 is pressed by the pressing piece, and the carrier switch 716 is turned on. As a result, the driving of the motor 711 is stopped and the state returns to the sales standby state.

After the contact between the cam protrusion 7151 and the base end 718a of the link lever 718 is released by the clockwise rotation of the output gear 715, the cam protrusion 7151 of the output gear 715 returns to the standby position. Although it abuts on the base end portion 717a of the other link lever 717 on the way, the cam projection 7151 is prevented from moving by allowing the locking piece 717c made of an elastic member to elastically deform and allowing the link lever 717 to rotate. Without returning to the return position. The link lever 717 returns to the standby posture of FIG. 16A by the action of the locking piece 717c when the cam projection 7151 passes.
