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 control device for a product dispensing device in a vending machine that alternately dispenses products in the front and rear directions from the storage column.

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 Japanese Utility Model Application Publication No. 51-74498. This is extremely expensive.

In view of this, the present invention is designed to control the dispensing devices with a single control switch regardless of the number of product dispensing devices even if the device has a plurality of product dispensing devices. The purpose is to minimize damage so that even if a part breaks down, the product will not be lost.

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

Reference numeral 2 denotes a product storage column which is supported approximately vertically on a mounting table 3 and stacks a large number of box-shaped products M such as cigarettes and gum back and forth. Dispensing ports 4 each having a sufficient area to send one product forward are provided at the lower ends of the front and rear surfaces.

The product dispensing device 5, which has a dispensing member 5a that slides on the placement platform 37, is attached to a movable 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. 14473, a bottle set up at one location on the peripheral edge of a rotating plate rotated 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. The electric motor rotates in response to a sales signal, and each time the rotary plate rotates 180 degrees, the moving platform 6 moves toward the rail 7.
Some move forward and backward along the

Another method, as in Utility Model Application No. 51-74498, is to integrate a loop-shaped internal gear body that meshes with a pinion rotated by an electric motor that rotates in response to a sales signal, and a movable base, so that the internal gear is rotated by the rotation of the electric motor. There is a so-called mangle gear mechanism in which a body and a moving table move forward or backward along a rail 7 to dispense products back and forth.

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

A fixing member, that is, a support plate 8 is fixed in the vertical direction to the right of the rightmost accommodation column 2, and axle rods 9a and 9b are fixed to the front and rear of the support plate 8, and the axle rod 9a , 9b are actuating members 10a, respectively.

10b is loosely fitted into the operating members 10a, 10b.
The operating member 10a is rotatable.

10b is common to all of the product dispensing devices 5 provided for each product storage column 2, and any of the product dispensing devices 5 operates as described below.

Further, between the front and rear operating members 10a and 10b, there is provided a switch operating member 12 whose intermediate portion is pivotally supported by a shaft 11 fixed to the support plate 8 so as to be freely rotatable.

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 10H.
2 and the rear operating member 1
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 denotes a biasing spring stretched between the two connecting members 15a and 15b to bias the switch operating member 12 to maintain the standby state, that is, the state in which the control switch 18 is pressed.

Note that the operating members 10a and 10b are connected to a plurality of the dispensing devices 5.
The operating parts 10C and 10 are arranged in the left direction, that is, in the depth direction in FIG. 2, so that the movement of any device can be captured.
d are extended.

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

The operation of the above configuration will be explained below with reference to FIG.

When a predetermined amount of money is inserted into a coin slot (not shown), a coin sorting and counting device (not shown) issues a sell signal.

Here, when the desired product selection switch 20A is activated, the selection relay 21A is energized, and furthermore, the relay 21A is self-held via its own contact 21a.

At this time, the drive device 22A of the product dispensing device 5 is energized through the contact of the selection relay 21A, and the moving platform 6 moves forward on the rail 7 from the state shown in FIG. 6, that is, starts moving from the standby state A. The dispensing member 5a starts pushing the product M.

Further, at this time, the control relay 23, which is normally energized, is de-energized by the energization of the selection relay 21A, so the on-delay timer 24 is energized but does not operate.

On the other hand, the movable table 6 eventually advances to the state shown in FIG. 4 and comes into contact with the actuating portion 10C of the actuating member 10a, and then advances further forward and connects the connecting member 15 to push the actuating member 10a forward as shown in FIG. The switch operating member 12 rotates about the shaft 11 as a fulcrum via a.

At this time, of course, the other actuating member 10b also rotates via the connecting member 15b (the state shown in FIG. 3).

Control switch 18 is therefore activated and capacitor C1 is charged.

Further, the movable table 6 enters the return path with state B in FIG. 3 as the top dead center.

The product M slides on the guide shoe 3a and reaches the sales outlet.

Then, when the movable table 6 reaches the state C shown in FIG.
Pressing operation is performed by 2.

Then, reset relay 2 is activated due to discharge of capacitor C1.
5 is energized, the self-holding of the selection relay 21A is released, the drive device 22A is de-energized and stopped, and the product dispensing device 5 enters a sales waiting state.

Then, the control relay 23 is energized and reset by releasing the self-holding of the selection relay 21A, so the on-delay timer 2
4 is de-energized and reset.

Further, the reset relay 25 is also de-energized after the capacitor C1 is discharged.

The delay time of the on-delay timer 24 is set to about 5 seconds, assuming that the energization time of the drive device 22A required for one sales operation is 2 seconds.

In the next sales operation, the product dispensing device 5 moves rearward to send out the product, moves further rearward from the position indicated by the chain dotted line 5' in Figure 4, and moves the actuating member 10b to the state shown in Figure 3, as described above. By the same operation, it returns to the position 5' in FIG. 4 and stops.

By the way, the operation in the case where, for example, the connecting member 15a comes off from the operating member 10a or the switch operating member 12 due to some kind of failure during the sales operation described above will be described.

Even if the moving table 6 moves and comes into contact with the actuating portion 10C of the actuating member 10a and moves further forward, the switch operating member 1
2 is in a state of limbo, the control switch 18 is pressed.
will stop working.

Therefore, the drive device 22A is kept energized, and the moving platform 6
This time, the product M enters the return route and then the outward route again, resulting in a defective state in which product M is not delivered. At this time, the failure indicator lamp 26 lights up via the NO contact of the control switch 1B, and the customer is informed of the failure. This can be displayed.

Furthermore, the on-delay timer 24 sets the delay time (
5 seconds), the contacts of the timer 24 are switched and the drive device 22A is de-energized, making it possible to minimize the above-mentioned malfunction.

However, as shown in FIG.
In the case where the biasing spring 19 tensioned between b is eliminated and the switch operating member 12 and support plate 8 are tensioned as shown by the broken line 19, the connecting member 15a is connected to the actuating member 1 as described above.
Even if the control switch 18 is removed from the switch operating member 12, the control switch 18 will be operated once in one reciprocation of the movable table 6.

In other words, the product dispensing device 5 dispenses two products for each sale.

In order to prevent this, it takes approximately 2 seconds for the selling operation to occur, so even if the delay time of the on-delay timer 24 is set to 3 seconds, for example, the product dispensing device 5 may operate depending on the load on its drive device. Not only is it difficult to prevent this completely because the time varies, but it is also possible that not even a single product will be produced, so this is not a very good solution.

The present invention overcomes these drawbacks.

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.

In addition, because the biasing spring that biases the switch operating member that operates the control switch to maintain it in the standby state is stretched between the two connecting members, damage caused by product failure due to failure can be kept to a minimum. The above-mentioned failure can be reliably dealt with.
