  The present invention relates to a vending machine door device that opens and closes the front surface of a vending machine body, and more specifically, an outer door that is rotatably attached to one end portion in the left-right direction of the vending machine body, and the outer door. The present invention relates to a door device for a vending machine having an inner door rotatably attached to the back surface of the vending machine.

  Conventionally, what was described in patent document 1 is known as a door apparatus of this kind of vending machine. This door device includes an outer door attached to the left end of a vertically long box-shaped vending machine main body having a front opening and a product storage portion therein, and is rotatable about an axis extending in the vertical direction. An inner door is provided on the rear surface of the door so as to be rotatable about an axis extending in the vertical direction near the axis. The former opens and closes the front of the vending machine main body, while the latter opens and closes the back of the outer door and has a detachable product display on the surface of the outer door.

  The inner door of the door device is opened and closed when maintenance of the product display is performed. Specifically, the maintenance work is performed as follows. First, the outer door is opened largely to the front of the vending machine body. In this case, the inner door rotates in front of the vending machine body together with the outer door, with the back surface of the outer door closed. Next, the inner door is rotated to the vending machine body side and opened. Thereby, the product display provided in the inner door is exposed to the outside, and the product sample and the product panel are exchanged or cleaned. And after completion | finish of a maintenance operation | work, an inner door is rotated to the outer door side, and the inner door is latched to an outer door in the state which closed the back surface. Then, the outer door is closed by rotating the outer door to the vending machine main body side.

  Such a door device generally closes the outer door by forcibly pressing the inner door toward the outer door as the outer door is closed, even when the inner door is not locked with the outer door closed. In this state, an inner door closing mechanism that automatically locks to the outer door is provided. Therefore, even if the operator does not intentionally close the inner door or forgets to close it after the product display maintenance work is completed, the inner door is removed by the inner door closing mechanism. With the back of the door closed, it is locked to the outer door.

  However, when the outer door is closed without closing the inner door, the following problem may occur. That is, an operator who does not know that the vending machine has an inner door closing mechanism or an operator unfamiliar with the operation of the vending machine door immediately before the inner door is automatically closed by the inner door closing mechanism. If you notice that you forgot to close the inner door and open the outer door, the free end of the inner door hits the side wall of the vending machine body, and that side wall gets in the way, and you can pull the inner door to the front of the vending machine body. It may disappear. This is because the center of rotation of the inner door is located inward of that of the outer door, so that when the outer door is opened in the above-described situation, the free end side of the inner door swells outward. This is because the inner door rotates. Further, if the outer door is forcibly opened while the inner door is in contact with the side wall of the vending machine body, the inner door may be deformed.

  The present invention has been made to solve the above-described problems. The outer door is closed without closing the inner door, and the outer door is opened before the outer door is completely closed. Even in such a case, an object of the present invention is to provide a vending machine door device that can prevent the inner door from being pulled out or deformed from the vending machine main body.

  Next, the operation of the inner door 24 when the outer door 22 is closed without closing the inner door 24 will be described with reference to FIGS. FIG. 7 shows a state in which the main door 3 is largely opened, and more specifically shows a state in which the outer door 22 is located at the outer door opening position while the inner door 24 is slightly opened. . From this state, first, the outer door 22 is pressed toward the vending machine body 2 side. Thereby, the outer door 22 rotates toward the outer door closed position. In this case, the inner door 24 has substantially the same angle as the beginning of the closing operation of the outer door 22 until the contact roller 61 of the inner door delivery device 51 contacts the inner door guide plate 52 on the vending machine body 2 side. While being held, it rotates together with the outer door 22. Further, as shown in FIG. 8A and the corresponding FIG. 10A, immediately before the contact roller 61 contacts the inner door guide plate 52, the contact roller 61 positioned at the protruding position It protrudes slightly to the right from the extended portion 72b of the door guide plate 52. Therefore, when the contact roller 61 contacts the inner door guide plate 52, it first contacts the front end of the extending portion 72b.

  Next, after the contact roller 61 contacts the inner door guide plate 52, the outer door 22 is further pressed toward the vending machine body 2 as shown in FIG. 8 (b) and the corresponding FIG. 10 (b). In addition, as the outer door 22 further rotates toward the outer door closing position, the entire inner door 24 moves to the left, and the contact roller 61 of the inner door feeder 51 moves the inner door guide plate 52. Rolling on the extended portion 72b and the inclined portion 72a. In this case, the contact roller 61 is pressed from the inner door guide plate 52, and thereby rotates to the retracted position side against the urging force of the torsion coil spring 62.

  Then, as shown in FIG. 9A, when the outer door 22 is further pressed toward the vending machine main body 2 and the outer door 22 reaches the outer door closing position and is completely closed, the spacer of the inner door 24 is reached. When 42 abuts on the front door 8 of the product storage / dispensing device 5 </ b> A, the inner door 24 rotates to the inner door closed position and is locked to the outer door 22 by the locking fitting 43. In this case, as shown in FIG. 11A corresponding to FIG. 9A, the stopper portion 56 of the inner door delivery device 51 comes into contact with the protruding portion 71 b of the inner door guide plate 52. When the outer door 22 is opened while the inner door 24 is locked to the outer door 22, the inner door 24 rotates together with the outer door 22 to the front of the vending machine body 2.

It is sent to the front of the vending machine main body 2 by the inner door delivery machine 51. Thus, the reason why the inner door 24 is sent forward is as follows. That is, as shown in FIGS. 8B and 10B, the contact roller 61 of the inner door delivery device 51 contacts the inclined portion 72a of the inner door guide plate 52 and the torsion coil spring 62 is attached. In a state in which it is pressed against the retreat position side against the force, a reaction force of the restoring force to the projecting position side of the torsion coil spring 62 acts on the contact roller 61 from the inclined portion 72a. The reaction force component acts in a direction in which the inner door 24 is rotated clockwise around the rotation shaft 23 a of the inner door hinge 23, that is, in a direction in which the inner door 24 is rotated forward of the vending machine body 2. To do. Thereby, when the outer door 22 is opened from the state of FIG. 8B, the inner door 24 is sent out to the front of the vending machine body 2.

  As described above in detail, according to the present embodiment, when the outer door 22 is closed without closing the inner door 24, the outer door 22 is opened before the outer door 22 is completely closed. In this case, the inner door 24 is fed forward of the vending machine body 2 by the cooperation of the inner door feeder 51 and the inner door guide plate 52. Therefore, for example, an operator unfamiliar with the door operation of the vending machine operates to close the outer door 22 without closing the inner door 24 and opens the outer door 22 before completely closing the outer door 22. Even in this case, unlike the conventional case, it is possible to prevent the inner door 24 from being pulled out from the vending machine body 2 or from being deformed.

  In addition, this invention can be implemented in various aspects, without being limited to the said embodiment described. In the embodiment, the case where the door device of the present invention is applied to a vending machine in which the vending machine main body and the main door both have a product storage unit has been described, but the main door has a product storage unit. It can of course be applied to vending machines that are not. Moreover, in such a main door, the present invention can also be applied with the rear door of the commodity display that is opened and closed when the commodity sample is exchanged or maintained as the inner door of the present invention.

  Further, in the embodiment, the rotatable contact roller 61 is used for the inner door delivery device 51, but instead, it is movable between the protruding position and the retracted position, and slides on the inner door guide plate 52. It is also possible to employ possible members.

  Furthermore, in the embodiment, the inner door guide plate 52 having the inclined portion 72a inclined with respect to the inner surface of the right side wall 4a of the case 4 is used, but the inclined portion 72a is not inclined and the right side of the case 4 is inclined. It is also possible to employ an inner door guide plate 52 that extends in the front-rear direction along the inner surface of the wall 4a. However, in this case, the contact roller 61 of the inner door delivery device 51 always comes in contact with the inner door guide plate 52 in a pressed state in front of the rotation shaft 23a of the inner door hinge 23.
