Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a control circuit for a vending machine equipped with a plurality of carousel shelves each having a product storage section (compartment) divided into a plurality of segments.
This simplifies operations when filling products.

[Prior art and its problems]

It goes without saying that vending machines have different dispensing mechanisms depending on the product, and the methods of filling the vending machines with products also differ depending on the dispensing mechanism.

The present invention has been made especially for the mechanism shown in Fig. 1, which has problems during filling. The products 3 are stored as shown in FIG.
When you reach part 4, you open door 4 and take out the product with your hand.

Generally, the control circuit for this type of mechanism is not shown, but when a coin is inserted and the selling price is reached, the coin sorting/counting machine issues a bend signal that allows the product to be sold, and when the customer presses the product selection switch. The bend relay is activated and holds itself, and this bend relay drives the product delivery motor to rotate the carousel 1 one pitch, transporting the compartment containing the product to the sales outlet, and sends a reset signal to the coin sorting and counting machine. do. Then, one pitch of rotation at this time is detected by a carrier switch, and when one pitch of rotation is detected, the self-holding of the bend relay is released and the product returns to the sales standby state. In this way, if sales progress and the number of products decreases or disappears,
The product is filled.

By the way, when filling products, with the conventional control circuit, even if the large front door 5 is opened, the hand cannot reach behind the carousel 1.
In the free bend state, it was necessary to push the product selection switch one by one and advance the rotating shelf 1 one pitch at a time to fill the product. Therefore, when filling a plurality of carousels with products, one switch operation is required for each carousel to fill one product, which is cumbersome and increases the time required for filling.

[Purpose of invention]

In view of the above-mentioned points, it is an object of the present invention to provide a control circuit for a vending machine that can simplify the operation when filling a plurality of carousels with products.

[Key points of the idea]

The present invention adds a free bend switch and a loading switch that has individual contacts connected in parallel to each of the product selection switches to the conventional sales control circuit, and controls the operation of the free bend switch. Based on this, a bend signal is generated to create a free bend state, and the B contacts of these bend relays are bridged to enable multiple bend relays to operate simultaneously. By doing so, multiple rotating shelves can be rotated at the same time by simply operating the loading switch after turning on the free bend switch, simplifying operations when filling multiple rotating shelves with products. That is.

[Example of idea]

The present invention will be described in detail below with reference to the drawings.

FIG. 2 is a circuit diagram showing an embodiment of the present invention, and shows a control circuit for a vending machine equipped with a plurality of (two) rotating shelves. In the diagram, _X1 is the first bend relay,
X ₂ is the second bend relay, XA is the auxiliary relay, XB
is a time-limited relay, M ₁ is the first bend motor, M ₂ is the second bend motor, MS ₁₁ and MS ₁₂ are the first carrier switch, MS ₂₁ and MS ₂₂ are the second carrier switch, and P ₁ is the first product selection. Switch, P ₂ is the second
product selection switch, FV is _a free bend relay, FVS ₁ and FVS ₂ are free bend switches with residual contacts, _and LD _{1 is} a loading switch. This is an addition to the sales control circuit.

In the following description of the circuit configuration and operation order, the names of relays, switches, etc. will be omitted and only the symbols will be used.

First, the normal sales operation will be explained. When coins are inserted and the selling price is reached, a bend signal is emitted from the coin sorting and counting machine. Suppose that, for example, _P1 of the product selection switch is pressed. Since XB is excited when the power is turned on, X ₁ becomes XB ₂ −P ₁ −MS ₁₁
is excited through. Then X ₁ becomes MS ₁₁ −X ₁₂ −
XA holds itself through X ₂₂ and at the same time XA becomes X ₁₁ −X ₂₁
is excited through. When XA is energized, XA ₂ closes and XA self-retains through MS ₁₂ − MS ₂₂ , and X ₁
XA ₂ − is maintained even if the bend signal disappears.
A self-holding circuit is formed through X ₂₁ −X ₁₁ −X ₁ −MS ₁₁ −X ₁₂ −X ₂₂ . On the other hand, when XA is energized, the b contact of XA ₂ opens, so that XB is briefly disconnected, and eventually the b contact XB ₂ of XB closes and drives M ₁ via the a contact X ₁₃ of X ₁ . Due to the rotation of M ₁ , MS ₁₁ and MS ₁₂ move simultaneously, releasing the self-holding of X ₁ and XA, and M ₁
The first carousel is rotated one pitch and stopped in position by the MS ₁₂ , and the sale is performed. and,
A reset signal is sent to the coin sorting and counting machine via XB ₁ - XA ₁ to return it to the sales standby state. Even when P ₂ is pressed in one sales operation, X ₂ is excited and M ₂ is driven according to the same sequence of operations, and the product on the second carousel is sold.

Now, when filling products, regardless of the bend signal from the coin sorting and counting machine, FVS ₁ and FVS ₂ , which have residual contacts, are turned on to generate a bend signal and to excite FV. The action of FV closes FV ₁ . Here, in order to enable bend relays X ₁ and X ₂ to operate at the same time, the b contact of X ₂₂ , which is used to selectively operate _bend relays X _{1 and} It's connected. Although it is not shown in the figure, if there are three or more sets of rotating shelves, a bridge circuit should be constructed corresponding to the b contact of each bend relay connected in series in order to operate it selectively during normal sales. . And each bend relay X ₁ , X ₂
In order to ensure that the product selection switches P ₁ and P ₂ are operated at the same time, the two contacts of the loading switch LD ₁ are connected to P ₁ , P ₂ so as to bridge P 1 , P ₂ and XB ₂ , respectively. ₂ are connected in parallel. Therefore, if LD ₁ is operated after FVS ₁ and FVS ₂ are turned on,
Both X ₁ and X ₂ are self-supporting, and M ₁ and M ₂ rotate together. Then, when it is detected by each carrier switch that the two rotating shelves have been rotated one pitch, M ₁ and M ₂ are stopped, and the two rotating shelves are stopped at their regular positions. In this way, a plurality of rotary shelves can be rotated simultaneously by one operation of LD ₁ .

As described above, when filling products, FVS ₁ and FVS ₂ are input to create a free bend state, and FV forms a circuit that bridges the b contact of X ₂₂ , and multiple bends can be performed by operating LD _1. Relay X ₁ , X ₂
At the same time, switch to a self-holding circuit, and 1 of LD ₁
Since multiple rotating shelves can be rotated one pitch at a time by one operation, it is no longer necessary to operate each bend relay once through the product selection switch to fill the product. Comparatively, the filling time can be significantly shortened.

[Effect of idea]

According to the present invention as described above, a free bend switch and a loading switch having individual contacts connected in parallel to each of the product selection switches are additionally provided to the conventional sales control circuit, Based on the operation of the free bend switch,
In addition to generating a bend signal to create a free bend state, we also bridged the b contacts of these bend relays, which are used to selectively operate bend relays in normal sales, so that multiple bend relays can operate at the same time. By turning on the free bend switch and operating the loading switch, multiple rotating shelves can be rotated at the same time. Therefore, in order to sequentially fill each compartment of a plurality of carousels with products, there is no need to operate the product selection switch for each carousel and rotate the carousel to fill the compartments, as is the case in the past. The operation when filling the shelves with products can be simplified.
Furthermore, when filling products, the sales control circuit can be used to rotate multiple carousels at the same time and stop the carousels at a fixed position. There is no need to worry about malfunctions in subsequent sales operations.
