The damper 41 has an engaging protrusion 41a that can be engaged with the shaft portion 11 of the commodity door, and engages with the commodity take-out door 10 through the engaging protrusion 41a. The damper 41 is for reducing the speed of the closing movement of the product take-out door 10.

  Such a third opening / closing unit 40 is applied to the outward opening type product take-out door 10. That is, the present invention is applied to the product takeout door 10 that moves forward and closes backward.

  In the vending machine having the above-described configuration, the product take-out door 10 can be opened and closed as follows. Here, the case where the 1st opening / closing unit 20 is provided is demonstrated.

  When a predetermined money is inserted and the product selection button 3 is pressed, the product carried out from the column inside the main body cabinet 1 reaches the product outlet 8. At this time, when the opening command is given from the controller, the motor 21 is driven to rotate forward, whereby the drive shaft rotates. As the drive shaft rotates, the actuator 22 provided in engagement therewith also rotates. At this time, the contact state between the actuator 22 and the closing detection microswitch 26a is released, and the closing detection microswitch 26a changes from the on state to the off state.

  Due to the rotation of the actuator 22, the connecting member 24 engaged with the actuator 22 via the spring 23 rotates in the same direction in synchronization with the actuator 22. As a result, the product takeout door 10 having the shaft portion 11 engaged with the connecting member 24 swings rearward around the shaft center of the shaft portion 11 and moves open. That is, the product take-out door 10 moves open against the urging force of the spring 23.

  When a part of the rotating actuator 22 comes into contact with the opening detection microswitch 26b, the opening detection microswitch 26b, which was in the off state, is turned on, and a signal indicating that the product take-out door 10 is in the opening position is sent to the controller. As a result, the drive of the motor 21 is stopped by the command from the controller, and the commodity take-out door 10 stops the opening movement at the open position. As a result, the product outlet 8 is opened, and the user can take out the product.

  After a predetermined time has passed, the motor 21 is driven in reverse by receiving a close command from the controller, whereby the drive shaft rotates in the reverse direction. By rotating the drive shaft, the actuator 22 provided in engagement therewith also rotates in the reverse direction. At this time, the contact state between the actuator 22 and the opening detection microswitch 26b is released, and the opening detection microswitch 26b changes from the on state to the off state.

  Due to the rotation of the actuator 22, the connecting member 24 engaged with the actuator 22 via the spring 23 rotates in the same direction in synchronization with the actuator 22. Thereby, the product take-out door 10 having the shaft portion 11 engaged with the connecting member 24 swings forward around the shaft center of the shaft portion 11 and closes and moves.

  When a part of the rotating actuator 22 comes into contact with the closing detection micro switch 26a, the closing detection micro switch 26a, which has been turned off, is turned on, indicating that the product take-out door 10 is in the closed position. As a result of outputting the signal to the controller, the drive of the motor 21 is stopped by a command from the controller, and the commodity take-out door 10 stops closing at the closed position. That is, the product outlet 8 is closed.

  As described above, in the first opening / closing unit 20, the motor 21 and the actuator 22 constitute a drive mechanism, and the spring 23 and the connecting member 24 constitute a first urging means. The vending machine including the first opening / closing unit 20 and automatically opening the product take-out door 10 (automatic opening structure) is configured to manually open the product take-out door 10 as follows. It can be changed to (manual opening structure).

  The above-described commodity take-out door 10 automatically swings backward and moves open. However, when changing to a door that manually swings backward and opens, FIG. As shown, after removing a part of the cover member 9, the fastening state by the fastening member is released, and the first opening / closing unit 20 is removed. At this time, the engagement state between the shaft portion 11 of the product take-out door 10 and the connecting member 24 is released, and the couplers 27a and 27b are removed. Then, the second opening / closing unit 30 as described above is attached to the position where the first opening / closing unit 20 is provided. Specifically, a fastening member such as a bolt is passed through the screw hole 34 a provided in the attachment piece 34 of the attachment metal 30 a and attached to the main body cabinet 1. At this time, the shaft portion 11 of the product take-out door 10 is caused to enter the engagement hole of the connecting member 33 to engage both. Thereafter, the replacement of the first opening / closing unit 20 to the second opening / closing unit 30 is completed by attaching a part of the cover member 9 removed earlier.

  In the vending machine to which the second opening / closing unit 30 is attached in this manner, when the user applies a pressing force to the product take-out door 10 from the front, the product take-out door 10 opens and moves rearward. As a result, the product outlet 8 is opened. On the other hand, when the product take-out door 10 is brought into a free state, the product take-out door 10 is closed and moved forward by the urging force of the spring 32, whereby the product take-out port 8 is closed. That is, the vending machine has been changed to a manual opening structure. Here, in the second opening / closing unit 30, the spring 32 and the connecting member 33 constitute second urging means.

  The vending machine may be changed from a structure in which the commodity take-out door 10 swings rearward and opens (inner opening structure) to a structure that swings forward and opens (outer opening structure). it can.

  As shown in FIG. 2, after removing a part of cover member 9, the fastening state by a fastening member is cancelled | released and the 2nd opening / closing unit 30 is removed. At this time, the engagement state between the shaft portion 11 of the commodity take-out door 10 and the connecting member 33 is released. Then, the third opening / closing unit 40 as described above is attached to the position where the second opening / closing unit 30 is provided. Specifically, a fastening member such as a bolt is passed through the screw hole 43 a provided in the attachment piece 43 of the attachment metal 40 a and attached to the main body cabinet 1. At this time, the engagement protrusion 41 a of the damper 41 is engaged with the shaft portion 11 of the commodity extraction door 10. And the makeup | decoration frame 8a which forms the lower edge of the goods outlet 8 is once removed, the lower end part of the goods extraction door 10 is located ahead of the goods outlet 8, and after that, the once-removed makeup frame 8a is made into the original location. Attach to. Thereby, the product take-out door 10 is always positioned in front of the product take-out port 8. At this time, the product take-out door 10 normally closes the product take-out port 8 by its gravity. By attaching a part of the cover member 9 removed previously, the replacement from the second opening / closing unit 30 to the third opening / closing unit 40 is completed.

  In the vending machine to which the third opening / closing unit 40 is attached in this way, when the user swings the product takeout door 10 forward, the product takeout door 10 opens and moves forward. As a result, the product outlet 8 is opened. On the other hand, when the product take-out door 10 is brought into a free state, the product take-out door 10 is closed and moved rearward due to gravity, whereby the product take-out port 8 is closed. At this time, the product take-out door 10 is closed while being decelerated by the action of the damper 41. Thus, the vending machine has been changed to an outwardly opening structure.

  As described above, in the vending machine according to the present invention, the product extraction door 10 is automatically opened and manually opened only by exchanging the first opening / closing unit 20 and the second opening / closing unit 30. It is possible to change between and the work is easy. In addition, since the attachment metal 20a that accommodates the constituent members of the first opening / closing unit 20 and the attachment metal 30a that accommodates the constituent members of the second opening / closing unit 30 have the same shape and size, the first opening / closing unit. There is no possibility that an excessive dead space is generated by exchanging 20 and the second opening / closing unit 30. Therefore, it is possible to easily change between a method of automatically opening and moving the product take-out door 10 and a method of manually opening and moving without causing an excessive dead space.

  According to the vending machine, the second door opening / closing unit 30 and the third door opening / closing unit 40 are exchanged and the lower end position of the commodity outlet door 10 is set forward of the commodity outlet 8 so that the commodity outlet door 10 can be changed. It can be changed between the inward opening method and the outward opening method, and the work is simple. Further, since the attachment metal 30a for accommodating the constituent members of the second opening / closing unit 30 and the attachment metal 40a for accommodating the constituent members of the third opening / closing unit 40 have the same shape and size, the second opening / closing unit. There is no possibility that an excessive dead space is generated by exchanging 30 and the third opening / closing unit 40. Therefore, the product take-out door 10 can be easily changed between the inner opening method and the outer opening method without causing an excessive dead space.

  Further, in the vending machine, when the first opening / closing unit 20 is attached, the driving force of the motor 21 is transmitted to the product take-out door 10 via the spring 23 to open and move the product take-out door 10. Even if there is an act or dangerous action such as pinching a hand, there is no possibility that the external force caused by the action is directly transmitted to the motor 21 and the force transmitted from the product take-out door 10 to the outside is only the urging force of the spring 23. Safety can be ensured without management by a sensor or the like. Therefore, the motor 21 can be prevented from being broken by an external force while securing safety with a simple structure.
