Movement is restricted.

  On the other hand, when the solenoid 40 is excited (driven), the plunger 43 is retracted, and the link member 27 is positioned upward against the urging force of the link spring 30. In a state where the link member 27 is disposed upwardly against the urging force of the link spring 30, as shown in FIG. 6, a stopper pin 28a is disposed at the upper end portion of the stopper pin insertion hole 263 and the pedal stopper pin is supported. The pedal stopper pin 28b is disposed at the upper end of the groove 264. In this state, the stopper abutting portion 253 of the second pedal member 25 abuts on the stopper pin 28a, thereby restricting the backward movement of the second pedal member 25 and resisting the biasing force of the second pedal member spring. The second pedal member 25 moves forward and is disposed at the advanced position. In addition, the rotation stopper member 29 is disposed at the retracted position while being in contact with the pedal stopper pin 28b by the urging force of the pedal operating member spring. When the rotation stopper member 29 is disposed at the retracted position, the pedal operating shaft 29a is disengaged from the fitting portion 243a of the first pedal member 24. Therefore, the first pedal member 24 moves backward due to the weight of the product and moves to the retracted position. Will be placed.

  In the commodity carry-out device configured as described above, the link member 27 is arranged below by the urging force of the link spring 30 in the sales standby state. In addition, the solenoid 40 is in a demagnetized state (non-energized state), and as shown in FIG. 4, the pedal stopper pin 28b is disposed at the restricting position, thereby restricting the backward movement of the rotation stopper member 29. Thereby, the pedal operation shaft 29a of the rotation stopper member 29 in which the retreat movement is restricted is fitted into the fitting portion 243a of the guide groove 243 of the first pedal member 24, and the retraction of the first pedal member 24 disposed at the advanced position is performed. Movement is restricted. As a result, the downward movement of the lowest product in contact with the first pedal member 24 is restricted, and the products are respectively stored in the product storage passage 13 in a lying posture. During this time, air adjusted to a predetermined temperature by driving the heat exchanger is supplied to the product storage 4, so that the product stored in the product storage passage 13 is maintained at a desired temperature state.

  By the way, in such a sales standby state, the second pedal member 25 is biased by the second pedal member spring, and the stopper pin 28a comes into contact with the recess 252 so that the second pedal member 25 moves backward from the product storage passage 13 ( (Standby position).

As a result, the downward movement of the next product is allowed, and then the next product is brought into contact with the first pedal member 24 that has moved forward, so that the downward movement is restricted and the product returns to the sales standby state.

  The commodity dispensing apparatus 20 further has the following configuration. As shown in FIGS. 7 and 8, the base member 21 has a support portion 32 formed at the lower edge thereof. The support portion 32 is formed by raising a part of the lower edge portion of the base member 21 between the one bearing piece 23 and the bearing portion 26, that is, between the components supporting the stopper shaft 28c. The stopper shaft 28c is supported in a mounted state.

  Moreover, as shown in FIG.9 and FIG.10, the shaft contact part 33 is provided in the base member 21 between the left-right paired bearing piece 23 and its own side wall 21a. The shaft abutting portion 33 is formed by bending a tongue-like portion formed by a notch, and a shaft (the first swing support shaft 24a and the first swing support shaft 24a) that penetrates the hole 231 of the bearing piece 23. 2 When the rocking support shaft 25a) is displaced in the direction of the central axis, it abuts and restricts further displacement. Further, as shown in FIG. 11, on the surface facing the insertion hole 22 of the bearing piece 23, the holes formed in the bearing piece 23 (the first swing support shaft 24a and the second swing support shaft 25a are respectively provided). A cylindrical bearing portion 232 that communicates with a through hole 231 is formed. The inner diameter of the bearing portion 232 is adjusted to be slightly larger than the outer diameter of the shaft (the first swing support shaft 24a or the second swing support shaft 25a) that passes through the bearing portion 232.

  Further, as shown in FIG. 12, the base member 21 is provided with the fixing piece 31 and the locking piece 34 described above. The fixed piece 31 is a pair of left and right parts formed by cutting and raising at the attachment site of the solenoid 40 in the base member 21. Each of the fixing pieces 31 includes a root portion 311 and a mounting portion 312.

  As shown in an enlarged view in FIG. 13, the root portion 311 is a portion continuous with the base member 21, and is separated from the base member 21 in a manner parallel to the driving direction of the solenoid 40, that is, the moving direction of the plunger 43. It is extended in the mode to do. Further, at both end portions of the root portion 311, curved portions 311 a that are curved toward the solenoid 40 are formed, so that the fixed piece 31 has a diaphragm structure. Further, an arcuate cutout 311b is formed in the curved portion 311a which is both end portions of the root portion 311.

  The attachment portion 312 extends from the extending end portion of the root portion 311 to the side. The attachment portion 312 is formed with a screw hole 312a through which a fastening member is inserted.

  The locking piece 34 is formed by bending the base member 21 stepwise, and locks the solenoid 40 to itself. A reference numeral 35 in FIG. 12 is a pressing piece that restricts the solenoid 40 from moving in a direction away from the base member 21 during the assembly operation of the commodity dispensing device 20.

  14 and 15 are schematic views showing the internal structure of the solenoid 40 shown in FIGS. The solenoid 40 exemplified here includes a yoke (fixed iron core) 41, a bobbin 42, and a plunger (movable iron core) 43. The yoke 41 is U-shaped, and the bobbin 42 is held by the yoke 41 around which a coil is wound. The plunger 43 is movable along the vertical direction, and is inserted into the bobbin 42. In such a solenoid 40, the suction part 41 a of the yoke 41 is provided in a manner to be detached from the bobbin 42. In the solenoid 40, when the coil is in a non-energized state, the separation distance between the suction portion 41a of the yoke 41 and the plunger 43 is approximately the same as that of the conventional configuration. That is, the extension length of the plunger 43 is increased by the amount by which the suction portion 41 a of the yoke 41 is detached from the bobbin 42. Thereby, the length of the plunger 43 in the bobbin 42 when the coil is in a non-energized state is longer than the conventional one.

  The base member 21 is provided with a reinforcing member 50 as shown in FIGS. The reinforcing member 50 is a flat plate member disposed in such a manner as to connect between the components supporting the stopper shaft 28 c, that is, between the one bearing piece 23 and the bearing portion 26, and stores the product of the link spring 30. The other side of the passage 13 is covered.

  According to the commodity dispensing apparatus 20 according to the present embodiment having the above-described configuration, the support portion 32 formed by raising a part of the lower edge portion of the base member 21 mounts the stopper shaft 28c. Since it supports in the state made into the state, it can prevent that an excessive load and a bending moment act on this stopper axis | shaft 28c, and are damaged. Therefore, it is possible to use the rotation stopper member 29 having a versatility applicable to various commodity storage passages 13 and having a small width dimension, and the rotation stopper member 29 can be shared. Therefore, it is possible to prevent the stopper shaft 28c of the rotation stopper member 29 from being damaged and reduce the manufacturing cost.

  Further, the shaft abutting portion 33 provided on the base member 21 makes it possible to shorten the length of each of the first swing support shaft 24a and the second swing support shaft 25a. The lengths of the dynamic support shaft 24a and the second swing support shaft 25a can be reduced to the minimum necessary length, and the material cost required for the first swing support shaft 24a and the second swing support shaft 25a is reduced. It becomes possible to make it. Further, the bearing piece 23 is provided with a cylindrical bearing portion 232 in a form communicating with a hole 231 (a hole through which each of the first swing support shaft 24a and the second swing support shaft 25a passes) 231. Even if the thickness of the base member 21 is reduced, the first swing support shaft 24a and the second swing support shaft 25a can be favorably supported.

  According to the commodity dispensing device 20, the fixing piece 31 that fixes the solenoid 40 is cut and raised in such a manner that the base portion 311 continuous with the base member 21 is parallel to the driving direction of the solenoid 40 (the movement direction of the plunger 43). Therefore, even when the thickness of the base member 21 is reduced, the base member 21 has sufficient strength, and there is no possibility that the root portion 311 deteriorates with time and is damaged. Therefore, the solenoid 40 can be favorably supported while reducing the manufacturing cost. In particular, a diaphragm structure for forming the curved portion 311a is provided at both end portions of the root portion 311 and an arc-shaped notch 311b is formed in the curved portion 311a, thereby eliminating a portion where stress is concentrated by driving the solenoid 40. Accordingly, the solenoid 40 can be favorably supported. Further, since the solenoid 40 can be locked by the locking piece 34 provided on the base member 21, the solenoid 40 can be easily positioned and can be assembled without the need for a jig or the like. .

  According to the commodity dispensing device 20, the engagement claw 27 a of the link member 27 that is inserted into the engagement hole 43 a of the plunger 43 that reciprocates by the solenoid 40 and engages with the plunger 43 is formed at the upper end of the link member 27. Is formed by being bent toward the opposite side of the product storage passage 13, it becomes possible to assemble the solenoid 40 after attaching the link member 27 during the assembly work of the product delivery device 20. The adverse effect of attaching the link member after attaching the solenoid as in the prior art can be eliminated, and the respective constituent members can be assembled independently. Therefore, the assembly work can be facilitated.

  According to the product dispensing apparatus 20, the solenoid 40 disengages the suction part 41a of the yoke 41 from the inside of the bobbin 42 around which the coil is wound, and the suction part 41a of the yoke 41 when the coil is in a non-energized state. And the distance from the tip of the plunger 43 inserted into the bobbin 42 is maintained, the length of the plunger 43 inside the bobbin 42 is increased. The initial suction force can be improved while maintaining the stroke. By improving the initial suction force as described above, the plunger 43 and the yoke 41 can be thinned, and as a result, the manufacturing cost can be reduced.

  According to the product dispensing device 20, the reinforcing member 50 connects between the components supporting the stopper shaft 28 c, that is, between one bearing piece 23 and the bearing portion 26, and the product storage passage of the link spring 30. 13, the link springs 30 are prevented from being damaged when they are installed back to back, and the components (one bearing piece 23 and the bearing portion 26) that support the stopper shaft 28 c are provided. Can be reinforced.
