Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is provided with a discharging device for discharging products discharged from a product storage section based on a sales instruction to a product take-out port, and also for removing cold air inside the machine. In order to prevent warm air from flowing out, dust from entering the cabin, and theft of the product (hands being caught in the launch device), the product outlet is connected to the product storage area through an opening/closing door. Regarding the connection Zuru vending machine.

[Conventional technology]

Conventional vending machines of this type are equipped with an anti-theft door that can be moved between a position blocking and opening the product passage by being guided by a long hole provided on the upper and lower surfaces of the product outlet. A sliding plate that can freely come into contact with the shaft of the opening/closing door protruding from the hole is provided on the top surface of the product take-out port, and the sliding plate is switched between a contact position and a retracted position by a solenoid that operates based on the removal of the product. Accordingly, the intentional opening of the opening/closing door during the sales standby is regulated by contact with the sliding plate (see, for example, Japanese Patent Laid-Open No. 131189/1989).

[Problem to be solved by the invention]

Conventional vending machines of this type have a theft-prevention structure provided near the product outlet, so there is a problem in that the anti-theft lock is easily released. For example, in the prior art described above, the sliding plate may be lifted through the elongated hole to release the sliding plate from the shaft of the opening/closing door.

The present invention aims to solve the above-mentioned problems of the prior art, and aims to provide a vending machine which has a simple structure but can reliably prevent the opening/closing door from being opened intentionally.

[Means to solve the problem]

In order to achieve the above object, the vending machine of the present invention has the following features:
Mechanical linkage means is provided for converting the force of moving the product placement shelf toward the product takeout port, which constitutes a part of the carrying out device, into an opening force of the opening/closing door, and the operation of the mechanical linkage means is provided. A restricting locking means is provided inside the vending machine at a position away from the product outlet.

[Function] The product shelf provides an opening force for the opening/closing door by its movement. The mechanical linking means works to convert the force of movement of the product shelf toward the product takeout port into an opening force of the opening/closing door and transmits the same, and the locking means is provided at a position away from the product takeout port. make things possible.

〔Effect of the invention〕

Therefore, the present invention has the following effects.

According to the vending machine of the present invention, since the locking means for preventing theft is located at a distance from the product takeout port, there is no fear that the lock will be released through the product takeout port, and there is no possibility that the locking means will be released through the product takeout port. It has the effect of reliably preventing the opening.

Moreover, when selling, the door is forcibly opened using the moving force of the product shelf, so the door can be opened reliably. Furthermore, since the moving force of the product shelf is effectively used, a special drive device is not required even though the product is opened forcibly, and the product can be manufactured economically.

〔Example〕

An embodiment in which the present invention is applied to a serpentine vending machine will be described with reference to the drawings.

Figure 3 shows the entire vending machine, with a serpentine (b) that stores a large number of products (A) vertically in a product storage section (B) inside the machine, placed at predetermined intervals in the front, back, left, and right directions. They are placed side by side. The serpentine (b
) is provided with a product input slot that opens forward, and a dispensing mechanism (not shown) is provided at the bottom of the serpentine (b) for dispensing selected products based on sales instructions.

The vending machine has an inner door (C2) and a front door (CI).
The dispensed product (A>) is transferred to the horizontal conveyance device if, which is installed at the bottom of the front door (CI) of the vending machine.
(1), or the product shelf of the elevator equipment (3) (
3a) Uke is stopped on top.

Figure 1 shows the internal structure of the front door (C,) in detail.
I'm showing you. As shown in the drawing, the horizontal conveyance device (1) is a small conveyor that conveys the delivered product (A) to the side of the elevator device (3) and passes it there. The elevator device (3) has a structure in which a chain (3C) is wound between upper and lower sprockets (3b), and a product placement Wi (3a) is attached to this chain (3c). The product (A) dispensed at the bottom of the vending machine is placed in the product loading port 1 (3a) at the product outlet (2) provided at the top of the front door (C1) so that it can be easily received by the purchaser. The product loading shelf (3a) is capable of being lifted up, and moves back and forth between the standby position for receiving and receiving the product (A) to be carried out and the product take-out port (2) based on the arrival detection of the product (A). The attitude of the tray (3d) is changed at the position of the product outlet (2) and the product (A) to be carried out is slid down. Reference numerals (3e) and (3f) in the drawings represent a spring and a locking claw for changing the posture, and the spring (3e) maintains the tray (3d) in the mounting posture, and the locking claw ( 3f), the product shelf (3a) is connected to the product take-out port (
When reaching step 2), the tray (3d) is changed to the dispensing position against the force of the spring (3e).

The product outlet (2) is designed to prevent cold or warm air from flowing out of the vending machine, to prevent dust from entering the machine, and to prevent products from being stolen or people getting their hands caught in the elevator system (3). An opening/closing door (4) is provided to prevent accidents. On the path of movement of the product shelf (3a) to the product take-out port (2), the opening/closing door (4) is closed by the contact force with the product shelf (3a).
) The following configuration is provided as a mechanical interlocking means for opening.

That is, a swing lever (5) whose free end enters the movement path of the product shelf (3a) and whose base end is pivoted outside the movement path, and a pivot lever (5) of the opening/closing door (4). An opening/closing operation lever (6) fixed to one end of the support shaft (4a) is provided, and a spring (5a) urges the swinging lever (5) to enter the movement path. The lever (5) and the opening/closing operation lever (6) are connected by a swinging lever (
5) The vertical pin (5b) is movably inserted into and engaged with the elongated hole (6a) formed in the opening/closing operation lever (6).

The chain (3C) has the following configuration as a locking means that restricts the operation of the swing lever (5) only when the product shelf (3a) is in a standby position at the lower end of the vending machine. It is a provision. That is, the chain (3c) is provided with an L-shaped locking protrusion (R), and the product shelf (3a)
The locking protrusion (R) enters into the engaging portion (5c) formed at the tip of the swinging lever (5) when the lever is in the standby position for receiving the dispensed product (A). It is provided on the chain (3C).

Therefore, when the product shelf (3a) is in the standby position at the lower end of the vending machine, the locking protrusion (R) engages with the engaging portion (5C) and engages with the opening/closing lever (6). Intentional opening of the door (4) is restricted via the swing lever (5). When the product selected based on the sales command is delivered onto the product placement 1111] (3a) and the product placement @ (3a) begins to move upward, the chain (3C) rotates. The locking protrusion (R) moves and the restriction is released. When the product (A) to be delivered is lifted to the product take-out port (2) by the upward movement of the product placement shelf (3a), the cam roll (3g) of the product placement 1lI (3a) is moved upward during the lifting process. It contacts the swinging lever (5) and swings the swinging lever (5) against the force of the spring (5a) (see Figure 2). The swinging of this lever (5) that starts midway through lifting is transmitted to the opening/closing operation lever (6) and gradually opens the opening/closing door (4), thereby opening the tray (3d).
When the posture of the container is changed and the product (A) to be carried out is slid down, the container becomes completely open (see the opening in Figure 2).

In this embodiment, an example of application to a serpentine vending machine has been described, but the present invention is not limited thereto. The conveyance device of the present invention is not limited to the elevator device described in the embodiment, but may be a horizontal conveyance device as long as it is a device that carries out products to a product outlet. The mechanical linking means is not limited to one that converts a contact force with the product shelf into a releasing force. For example, a pinion gear may be provided on the product shelf, and the product may be moved along the movement path of the product shelf. A rack gear that meshes with the pinion gear may be provided near the outlet, and the opening/closing door may be opened using the rotational force of the pinion gear when the product placement shelf approaches the product outlet. Furthermore, if the structure of the carrying-out device is effectively utilized to switch between locking and releasing the locking means as in the embodiment, the structure can be simplified; A special driving means may be provided for this purpose, and the present invention suffices as long as the locking means is provided at a position away from the product outlet.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
