As shown in FIG. 1, when two product carry-out devices 6 are arranged at the boundary between two product passages 53, each product carry-out device 6 is placed back to back, but each product made back-to-back The configuration of the mutual bearing member 63, link member 64, rotation stopper 66, and solenoid 69 of the carry-out device 6 is prevented from contacting and interfering with each other, thereby reducing the size of each product carry-out device 6 back to back. This is to improve efficiency. In addition, when the two product carry-out devices 6 are placed back to back, the tip surface 671 is disposed in order to prevent the tip surfaces 671 of the mutual flappers 67 at the retracted position from interfering with each other. It is formed in a comb-teeth shape. Of course, the extension portion 674 of the flapper 67 is similarly formed.

  The operation of the commodity carry-out device described above will be described with reference to FIGS. 2 and 5 to 7.

  First, the form shown in FIG. 2 is a sales standby state. The sales standby state is a state where the solenoid 69 is not energized and the link member 64 is urged downward by the link spring 643. That is, the upper link shaft 101 moves downward along the long groove 631 of the bearing member 63, and the lower link shaft 102 moves downward along the long groove 632 of the bearing member 63. In this sales standby state, the pedal 65 is in the advanced position by the elastic biasing force of the pedal spring 103a. Further, the pedal 65 receives the load of the product G because the product G at the lowest position of the product passage 53 is in contact with the holding surface 651. In the sales standby state, the rotation stopper 66 is at the advanced position by the elastic biasing force of the rotation stopper spring 104a. Further, the rotation stopper 66 receives the load of the product G applied to the pedal 65 because the support shaft 106 is in contact with the contact surface 653d of the deformed groove 653 in the pedal 65. Furthermore, the rotation stopper 66 is locked to the link member 64 by the lower link shaft 102 being fitted in the lock groove 661, so that its advance position is maintained. Thereby, the rotation stopper 66 maintains the advance position of the pedal 65 and prevents the pedal 65 from moving to the retracted position. Further, in the sales standby state, the flapper 67 is in the retracted position by the elastic biasing force of the flapper spring 105a. That is, in the sales standby state, all the products G are associated with the products G at the lowest position of the product passage 53 held on the holding surface 651 of the pedal 65 that is maintained at the advanced position by the rotation stopper 66. Is held. Further, in the sales standby state, since the flapper 67 is in the retracted position, the merchandise G is not involved.

  Next, the merchandise carry-out device 6 carries out the merchandise G as shown in FIGS. 5 to 7 in accordance with the sales instruction of the vending machine. As shown in FIG. 5, when the solenoid 69 is energized according to the sales command, the link member 64 is pulled upward against the elastic biasing force of the link spring 643 via the plunger 69a. Then, the lower link shaft 102 is detached from the lock groove 661 of the rotation stopper 66. When the lower link shaft 102 is disengaged from the lock groove 661, the rotation stopper 66 is permitted to move to the retracted position around the rotation stopper shaft 104. Here, the load of the product G is applied to the pedal 65 whose advanced position is maintained by the rotation stopper 66. That is, when the rotation stopper 66 is permitted to move to the retracted position, the pedal 65 is also permitted to move to the retracted position around the pedal shaft 103 and resists the elastic biasing force of the pedal spring 103a due to the load of the product G. And move toward the retracted position. As a result, the support shaft 106 of the rotation stopper 66 comes out of contact with the contact surface 653d of the pedal 65 and contacts the first guide surface 653a.

  Next, as shown in FIG. 6, the solenoid 69 is continuously energized, and the link member 64 is further pulled upward against the elastic biasing force of the link spring 643. Then, the pedal 65 further moves toward the retracted position against the elastic biasing force of the pedal spring 103a due to the load of the commodity G. As the pedal 65 moves, the rotation stopper 66 is guided by the support shaft 106 slidingly contacting the second guide surface 653b from the first guide surface 653a of the pedal 65, and the elastic biasing force of the rotation stopper spring 104a. Move toward the retracted position against

  Next, as shown in FIG. 7, the solenoid 69 is continuously energized, and the link member 64 is pulled up most against the elastic biasing force of the link spring 643. Then, the pedal 65 reaches the retracted position due to the load of the product G. As the pedal 65 moves, the rotation stopper 66 is guided by the support shaft 106 slidingly contacting the second guide surface 653b of the pedal 65 to reach the retracted position. At this time, when the product G at the lowest position can pass between the holding surface 651 of the pedal 65 and the passage width defining plate 62, the product G is detached from the lower side of the product carry-out device 6 and is taken out from the vending machine. It leads to an exit (not shown).

  Further, as shown in FIGS. 5 to 7, when the link member 64 is pulled upward from the sales standby state, the upper link shaft 101 is pulled upward by the upper engaging portion 641 of the link member 64, and the flapper 67. The groove 672 is in sliding contact with the sliding contact surface 672a of the groove 672 so as to be separated from the groove 672. Then, the flapper 67 moves toward the advanced position against the elastic biasing force of the flapper spring 105a around the flapper shaft 105 by the sliding contact surface 672a being pushed by the upper link shaft 101 moving upward. While the solenoid 69 is energized, the flapper 67 is maintained in the advanced position by the upper link shaft 101 being in contact with the sliding contact surface 672a. Then, the flapper 67 reaching the advance position contacts the product G having the tip surface 671 in the second position from the bottom, and holds the product G in the second position between the tip surface 671 and the passage width defining plate 62. To do. As a result, only the product G at the lowest position is carried out.

  Finally, when the product G at the lowest position is carried out, the product 65 at the second position from the bottom is held by the flapper 67 at the advanced position, so that the pedal 65 is released from the load of the product G. Then, the pedal 65 moves toward the advanced position by the elastic biasing force of the pedal spring 103a, and the rotation stopper 66 moves toward the advanced position by the elastic biasing force of the rotation stopper spring 104a. Then, the contact surface 653d contacts the support shaft 106 of the rotation stopper 66 that has returned to the advanced position (see FIG. 2). As a result, the pedal 65 is maintained at the advanced position and is prevented from moving to the retracted position by the rotation stopper 66.

  Further, when the lowest product G is unloaded, the unloading of the solenoid 69 is detected by the unillustrated product unloading detecting means detecting the unloading of the product G. That is, the link member 64 moves downward by the elastic biasing force of the link spring 643. Then, the lower link shaft 102 is pushed downward by the lower engaging portion 642 of the link member 64 and moves downward along the long groove 632 of the bearing member 63. As a result, the lower link shaft 102 is fitted into the lock groove 661 of the rotation stopper 66, and the pedal 65 and the rotation stopper 66 return to the advanced position (position in the sales standby state shown in FIG. 2).

  On the other hand, when the energization of the solenoid 69 is turned off and the link member 64 is moved downward by the elastic biasing force of the link spring 643, the upper link shaft 101 is pushed downward by the upper engaging portion 641 of the link member 64, It moves downward along the long groove 631 of the bearing member 63. As a result, the flapper 67 is released from the upper link shaft 101 and returns to the retracted position (position in the sales standby state shown in FIG. 2) by the elastic biasing force of the flapper spring 105a. And the goods G which were the 2nd position from the bottom currently hold | maintained with the flapper 67 are released, and reach the holding surface 651 of the pedal 65 which has returned to the advance position.

  In the above-described merchandise carry-out operation, the sold-out detection means 68 has the detection piece 681 pushed to the retracted position against the elastic biasing force of the detection piece spring 683 by the second product G from the bottom. For this reason, it is detected that there is a product G that can be sold with the switch 682 turned off. In this manner, the sold-out detection means 68 detects that there is a product G that can be sold when the product G at least the second position from the bottom exists in the product passage 53. On the other hand, when only the lowest product G is stored in the product passage 53, the sold-out detection means 68 does not have the product G that pushes the detection piece 681, so the detection piece 681 is elastically attached to the detection piece spring 683. It reaches the advance position by power. For this reason, it is detected that there is no product G that can be sold because the switch 682 is pushed by the arm 681b to be turned on.

  By the way, in order to attach the above-described product carry-out device 6 to the product passage 53, as shown in FIG. 8, the upper engaging portion provided at the upper end portion of the substrate 61 with respect to the upper pin 7a laid between the left and right side plates 51. Similarly, the upper engaging portion 61 d provided at the lower end portion of the substrate 61 is engaged with the lower pin 7 b installed between the left and right side plates 51.

  Here, the commodity carry-out device 6 according to the present embodiment has an extension portion 654 that extends to the left and right outwards of the substrate 61 in the pedal 65, and an extension that extends to the left and right outwards of the substrate 61 in the flapper 67. Part 674. Therefore, the spacer 8 is interposed between the side edge of the substrate 61 and the side plate 51 of the product passage 53, so that the substrate 61 of the product carry-out device 6 is restricted from moving along the upper and lower pins 7a and 7b. Therefore, between the width H1 between the left and right side plates 51, the substrate 61 has a width h smaller than the width H1, but the pedal 65 and the flapper 67 as the holding portions include the extension portions 654 and 674, and the left and right side plates. It has a width corresponding to the width H1 between 51. The width H1 between the left and right side plates 51 is formed corresponding to a product G (for example, a 500 ml can) having a relatively long longitudinal direction. That is, the pedal 65 and the flapper 67 having the extending portions 654 and 674 appropriately hold a product G (for example, a 500 ml can) having a relatively long longitudinal direction.

  On the other hand, as shown in FIG. 9, for the product passage 53 having the width H2 between the left and right side plates 51 formed corresponding to the product G (for example, a 350 milliliter can) having a relatively short longitudinal direction, The product carry-out device 6 using the substrate 61 is attached. The width h of the substrate 61 is substantially the same as the width H <b> 2 between the left and right side plates 51 of the product passage 53. In this case, the pedal 65 ′ and the flapper 67 ′, which are the holding portions, do not have the extending portions 654 and 674, but adopt a known form that fits in the opening 61 a of the substrate 61. That is, the pedal 65 ′ and the flapper 67 ′ that do not have the extending portions 654 and 674 appropriately hold the product G (for example, a 350 milliliter can) having a relatively short longitudinal direction.

  As described above, the product carry-out device 6 of the vending machine according to the present embodiment extends to the product passage 53 formed corresponding to the product G (for example, a 500 milliliter can) having a relatively long longitudinal direction. The pedal 65 having the portions 654 and 674 and the flapper 67 are employed to appropriately hold the product G having a relatively long longitudinal direction. On the other hand, for the product passage 53 formed corresponding to the product G having a relatively short longitudinal direction (for example, a 350 ml can), a pedal 65 ′ and a flapper 67 ′ having no extending portions 654 and 674 are employed. And the goods G whose comparatively short longitudinal direction is hold | maintained suitably. As a result, according to the width of the product passage 53 formed corresponding to the longitudinal direction of the product G, it is possible to adopt the product carry-out device 6 having the same main configuration other than the pedals 65 and 65 ′ and the flappers 67 and 67 ′. It becomes possible.

  Therefore, in the above-described merchandise unloading device of the vending machine, the pedal 65 and the flapper 67 as the holding portions having the extending portions 654 and 674 extending to the left and right outward of the substrate 61 are provided. By sharing the main configuration other than the flapper 67, it is possible to provide versatility to be attached to each product passage 53 formed corresponding to products having different lengths.

  In the above-described embodiment, the pedal 65 serving as the first holding unit is supported on the pedal shaft 103 and the flapper 67 serving as the second holding unit is supported on the flapper shaft 105. Although not clearly shown in the figure, the pedal 65 and the flapper 67 may be supported on one shaft. Furthermore, in embodiment mentioned above, it has the pedal 65 as a 1st holding | maintenance part, and the flapper 67 as a 2nd holding | maintenance part separately, hold | maintains the goods G of the lowest position with the pedal 65 in a sales standby state, Although it is configured to hold the product G in the second position from the bottom by the flapper 67 in the sales state, the present invention is not limited to this, and a holding unit in which the pedal 65 and the flapper 67 are integrated may be used, although not explicitly shown in the drawing.
