A so-called serpentine vending machine that sells products such as canned beverages is known.
[0003]
As shown in FIG. 9, in the vending machine main body 2 whose front opening is opened and closed by the front door 1, the storage conveyance paths 5 for storing products 4 such as cans extend vertically in a meandering manner. Three to six rows (in the case of four rows are shown in FIG. 9) are arranged in the front-rear direction. Between the lower ends of the storage conveyance path 5, a product delivery device 6 for sequentially delivering the stored products 4 is provided in every other row, and the product 4 delivered by the product delivery device 6 is sent by a chute 7. It is guided and paid out to the product outlet 8.
[0004]
As shown in FIG. 10, the commodity dispensing device 6 is a state in which a pair of dispensing units 10 are arranged back to back, and a commodity width regulating plate 9 is provided at a position facing the dispensing unit 10 across the storage conveyance path 5. The payout units 10 are arranged so as to face the lower end portions of the storage conveyance paths 5.
[0005]
As this type of payout unit 10, there is one disclosed in JP-A-11-232542. As shown in FIGS. 11 and 12, the payout unit 10 is disposed so as to face the lower end portion of the storage conveyance path 5, and is supported by the frame 11 having a plurality of opening windows and the like. An upper stopper 13 that is pivotally supported by the formed upper shaft 12 and protrudes into the storage transport path 5 to restrict the second product 4 from dropping from below the storage transport path 5. A lower stopper 15 that is pivotally supported by the supported lower shaft 14 and protrudes into the storage conveyance path 5 to regulate the fall of the first product 4 from below in the storage conveyance path 5, and a dispensing unit 10 is arranged on the back surface side of the frame 11 that does not face the storage conveyance path 5 and is connected to a solenoid 16 for raising and lowering its retracting portion 16a and an upper end thereof to the retracting portion 16a of the solenoid 16; A drive arm 17 having a return spring 18 biased downward via a drive pin 20 locked to the lower end, and a groove portion 13b between a protrusion 13a that is inserted into the upper portion of the drive arm 17 and bulges to the back side of the upper stopper 13. The upper drive pin 19 inserted into the lower end of the drive arm 17, the lower drive pin 20 inserted into the lower end of the lower stopper 15 and capable of coming into contact with the protrusion 15a that bulges to the back side of the lower stopper 15, the upper stopper 13 and the lower The stopper 15 is fixed to the frame 11 so as to extend vertically at a position near the center of the back surface side of the stopper 15, and supports the longitudinal intermediate portions of the upper shaft 12 and the lower shaft 14 through insertion holes (not shown), Receiving portions having long pin holes 21c and 21d for guiding one end sides of the upper drive pin 19 and the lower drive pin 20, respectively. 21 and is integrally formed with the frame body 11, and is detachably attached to the frame body 11 and a rising piece 22 for guiding the other end sides of the upper drive pin 19 and the lower drive pin 20 by the long hole shape portions 22a and 22b. A harness guide 23 for guiding the harness of the solenoid 16 and the like is provided.
[0006]
When the solenoid 16 is not energized, the drive arm 17 is pulled downward by the urging force of the return spring 21 and engages with the upper drive pin 19 inserted through the drive arm 17 as shown in FIG. While the upper stopper 13 is in the retracted posture, the lower stopper 15 is pushed out by the lower drive pin 20 inserted through the drive arm 17 to be in the protruding posture. Thereby, the drop of the product 4 at the lower end of the storage conveyance path 5 is regulated by the lower stopper 15, and the commodity 4 in the storage conveyance path 5 is held.
[0007]
When the solenoid 16 is energized, as shown in FIG. 12, the retracting portion 16a of the solenoid 16 is raised, so that the drive arm 17 is moved upward, and the upper stopper 13 that engages with the upper drive pin 19 is pushed out to protrude. On the other hand, the lower drive pin 20 is disengaged from the protrusion 15a of the lower stopper 15, and the lower stopper 15 is rotated to be stored. Accordingly, the lower stopper 15 stores the lower product 15 while the second product 4 falling from the lower side of the storage conveyance path 5 is regulated by the upper stopper 13 and the product 4 above the second lower side of the storage conveyance path 5 is held. Since it is in the posture, there is no longer anything that regulates the drop of the first product 4 from below the storage conveyance path 5, and only this product 4 is paid out.
[0008]
Since the pair of payout units 10 are arranged in a back-to-back state without interfering with each other, the solenoid 16, the drive arm 17, the upper drive pin 19, the lower drive pin 20, and the return spring 18 are arranged biased to one side, Correspondingly, the protrusion 13a of the upper stopper 13 that engages with the upper drive pin 19 and the protrusion 15a of the lower stopper 15 that contacts the lower drive pin 20 are also provided on one side.
[0009]
Here, the upper drive pin 19 and the lower drive pin 20 are disposed through the receiving member 21 that supports the longitudinal intermediate portions of the upper shaft 12 and the lower shaft 14. Therefore, since there is nothing that restricts the position of the upper drive pin 19 and the lower drive pin 20 in the lateral direction at the end portion on the receiving member 21 side, the lateral direction of the upper drive pin 19 and the lower drive pin 20 is reduced. In order to restrict the movement, the upper drive pin 19 and the lower drive pin 20 have large-diameter heads (headers) 19a and 20a at one end, and the upper drive pin 19 and the lower drive pin 20 have a large diameter. The heads 19a and 20a are sandwiched between the rising piece 22 and the harness guide 23 so as to be regulated in position. Further, as shown in FIG. 13, the upper stopper 13 has a recess 13c formed on the back surface thereof and a notch 13d formed on the tip thereof in order to avoid interference with the receiving member 21. .
[0010]
[Problems to be solved by the invention]
By the way, in such a conventional vending machine product delivery device, the receiving member 21 supports the longitudinal intermediate portions of the upper shaft 12 and the lower shaft 14 to prevent the upper stopper 13 and the lower stopper 15 from being bent. Also serves as a role. However, since the upper drive pin 19 and the lower drive pin 20 pass through the receiving member 21, the strength of the receiving member 21 is insufficient, and the upper stopper 13 and the lower stopper 15 are reliably bent. There is a possibility that it cannot be prevented, resulting in problems such as defective payout and multiple bottle discharge.
[0011]
Further, since the upper drive pin 19 and the lower drive pin 20 penetrate the receiving member 21 and there is nothing that restricts the position in the lateral direction at the end on the receiving member 21 side, the upper drive pin 19 and the lower drive pin 20 As described above, a device having large-diameter heads 19a and 20a at the opposite end is required, and the manufacturing cost is increased accordingly.
[0012]
Further, since the notch 13d is formed at the tip of the upper stopper 13, the tip of the upper stopper 13 is easily bent so as to be twisted in the rotation direction (circumferential direction), thereby supporting the product 4. There is a possibility that it cannot be supported by bending, and in this case, there is a concern that a large number of books may be dispensed at a time. In addition, when the product 4 is a PET bottle having a substantially square cross section, the corner of the product 4 is easily caught by the notch 13d of the upper stopper 13, and in this case, the upper stopper 13 does not return to the accommodation position side. There is a risk of a so-called return failure state.
[0013]
The present invention solves the above-mentioned problems, and there is no need for an automatic vending machine in which the upper stopper and the lower stopper are not bent abnormally, the upper stopper is not returned to a defective state, and the manufacturing cost can be reduced.
