Description

[Detailed description of the invention] This invention consists of a plurality of product storage columns in which a large number of products are stacked one on top of the other, arranged in parallel, and a product dispensing device provided for each storage column that moves in a straight line and reciprocates with a drive device to deliver the desired amount for each sale. The present invention relates to a vending machine that alternately dispenses products before and after the storage column, and relates to a control device for the product dispensing device.

Conventionally, this type of vending machine has been provided with a control switch for controlling the drive device for each product dispensing device, as shown in Utility Model Application Publication No. 51-74498. It was extremely expensive.

In view of this, the present invention is designed so that even if a plurality of product dispensing devices are provided, they are controlled by a single control switch regardless of the number of product dispensing devices.

An embodiment of the present invention will be described below in detail based on the drawings.

Reference numeral 1 denotes a main body of the vending machine, 2 a product storage column which is supported substantially vertically on a mounting table 3 and stacks a large number of box-shaped products M such as cigarettes and gum back and forth; A dispensing opening 4 having an area sufficient for sending one product forward is provided at the lower end of the front and rear surfaces of the column.

The product dispensing device 5, which has a dispensing member 5a that slides on the placement table 3, is attached to a moving platform 6 driven by a drive device (not shown) so as to reciprocate forward or backward in response to a sales signal. A moving table 6 is placed on rails 7.

Various configurations of the reciprocating drive device for the movable table 6 are conventionally known, and any of them may be used.
As in No. 8-14473, a pin set up at one location on the peripheral edge of a rotary plate that rotates by the rotation of an electric motor and a horizontal groove provided on the lower surface of the moving table 6 are slidably fitted together. In some models, an electric motor is rotated in response to a sales signal, and thereby the movable platform 6 moves forward and backward along the rail 7 every time the rotary plate rotates 180 degrees.

Another method involves rotatably supporting a pinion, which is rotated via a speed reduction mechanism by an electric motor started by a sales signal, on a swinging arm that is pivotally supported on a fixed member. A mangle rack with circular internal teeth is supported on a frame so that it can reciprocate linearly.
The mangle rack moves forward as the pinion rotates, and when the pinion engages along the arc at the front end of the mangle rack, the swinging arm rotates and the mangle rack moves backward, and the moving platform 6 is attached to the mangle rack. It moves forward and backward due to its position.

Such a mechanism was proposed in Utility Model Application No. 52-32399 and Utility Model Application No. 5
This is common in publications such as No. 1-74498 and Utility Model Application Publication No. 52-23595.

The product dispensing device 5 is provided for each product storage column 2.

A support plate 8 serving as a fixing member is fixed vertically to the right side of the rightmost storage column 2.

Axial rods 9a and 9b are fixed to the front and rear portions of the support plate 8, and the shaft rod 9a.

The upper ends of actuating members 10a and 10b are loosely fitted into the respective product storage columns 9b, and the actuating members 10a and 10b are rotatable. This is common to all of the product dispensing devices 5 provided, and any of the product dispensing devices 5 operates as described below.

And the operating member 10a before and after this. A switch operating member 12 is provided between 10b and is rotatably supported at its intermediate portion by a shaft 11 fixed to the support plate 8.

Both ends of the connecting member 15a are loosely fitted into a support shaft 13 fixed to the upper part of the operating member 12 and a support shaft 14 fixed to the front operating member 10a.
The support shaft 16 fixed to the lower part of the and the rear operating member 10
Both ends of the connecting member 15b are loosely fitted onto a support shaft 17 fixed to the connecting member 15b.

Reference numeral 1B denotes a control switch for controlling operation/stop of the drive device of the product dispensing device 5.

Reference numeral 19 indicates the upper part of the switch operating member 12 and the support plate 8.
A biasing spring tensioned between the control switch and the control switch constantly biases the operating member 12 in the rearward direction to maintain the switch operating member in a standby state, that is, in a state in which the control switch 18 is pressed. .

The actuating members IQa and 10b are arranged in the left direction, that is, in the depth direction in FIG.
, 10d are extended.

Furthermore, downwardly inclined guide shoes 3a and 3b are formed at the front and rear of the mounting table 3.

The operation of the above configuration will be explained below.

First, explanation will be given by taking the product dispensing device 5 on the rightmost side as shown in FIG. 2 as an example. FIG. 1B is pressed.

The drive device (not shown) of the product dispensing device 5 in the standby state A due to a sales command is energized, and the movable table 6 moves forward on the rail 7, and the dispensing member 5a is moved forward on the rail 7. Start pressing the lowest product M.

Then, the moving table 6 eventually moves to the operating portion 1 of the operating member 10a.
0C, and moves further forward to release the actuating member 10a.
In order to push the switch forward, the switch operating member 12 rotates about the shaft 11 via the connecting member 15a.

At this time, of course, the actuating member 1 is connected via the connecting member 15b.
0b also rotates to the state shown in FIG.

Therefore, the control switch 18 is actuated, but the moving platform 6 enters the return path with state B as the top dead center.

At this time, the product M slides on the guide shoe 3a and reaches the sales outlet.

When the movable table 6 is in state C, the switch operating member 1
2 is rotated about the shaft 11 as a fulcrum by the biasing spring 19 and returned to its original state, and the control switch 18 is pressed again by the switch operation member 12 to stop the drive, and the product dispensing device 5 is activated when the product is ready for sale. It is a state.

In the next selling operation, the product M is delivered to the rear by moving the product dispensing device 5 rearward, and the device of the present invention similarly pushes the actuating member 10b backward so that each part is in the state shown in FIG. It operates as follows.

It should be noted that the product dispensing device 5 indicated by the two-dot chain line is the one located to the left of the product dispensing device 5 located on the rightmost side.

As described above, in the present invention, a plurality of product storage columns are arranged side by side in which a large number of products are stacked one on top of the other, and a product dispensing device that is provided for each storage column and moves in a straight line and reciprocates by a drive device allows the product to be stored as desired for each sale. In a vending machine that alternately dispenses products from the front and back of the column, the operation of each dispensing device can be reliably captured, making it possible to control the drive device of each dispensing device with a single control switch, making it extremely inexpensive. It is something.
