The present invention relates to an ice cream selling machine, and more particularly to an apparatus for detecting the sale of ice cream.

Ice cream vending machines, unlike vending machines, in which selected drinks or items are automatically discharged according to the sales price, the mixed ice cream is stored in a container and the seller discharges an appropriate amount of ice cream. It is a device to sell.

That is, as shown in FIG. 1, when the ice cream container V is placed on the lower portion of the cap A installed on the front plate of the main body B, and the lever L is pulled downward, the rotation is simulated. As shown by the line, the piston (P) is moved upward along the cylinder (Clinder: C) to open the outlet (O) of the cap (A). At the same time, the detection device (not shown) detects this, and accordingly, the transfer screw S is rotated by a motor (M) so that the ice cream in the discharge pipe (G) supplied from the raw material container (X) is moved toward the cap (A) side. It is conveyed and discharged to the lower part of the cylinder C through the discharge port O.

In this way, the ice cream vending machine sells the ice cream by selectively driving the motor M according to the rotation of the lever L. In the ice cream vending machine, a sales sensing device for detecting the rotation of the lever L is indispensable. to be.

Figure 2 schematically shows such a conventional sales sensor. This is because the sensing rod 1 is inserted into the sleeve 2 of the main body B so that the sensing rod 1 is movably and the elastic bias is lowered by the plurality of springs 3 so that the front end of the piston of the sales device ( P) A micro switch (4) which is in contact with the upper end and operated by the intermittent plate 5 of the main body B is installed at a predetermined position of the sensing rod 1. Accordingly, when the piston (P) is raised by the rotation of the lever (L), the sensing rod (1) is raised together, the micro switch (4) is opened (open), the motor (M) is driven to sell ice cream, When the piston (P) is lowered, the sensing rod (1) is simultaneously lowered to close the micro switch (4) by the interruption plate (5) to stop the motor (M) to stop selling.

By the way, when the sales detection apparatus of the conventional ice cream vending machine is provided with a plurality of ice cream sales outlets, not only the separate sleeves 2 and springs 3 should be provided for each sales outlet, but also structured by a large number of components. It became complicated and the production was very troublesome. In addition, since the sensing rod 1 is configured to return by the elastic restoring force of the spring 3, when the spring 3 deteriorates due to prolonged use, the sensing rod 1 cannot be returned, and thus the motor M is continuously driven. There was also a problem that there is a great risk of failure. Therefore, conventionally, the safety and reliability of the use of the ice cream vending machine could not be guaranteed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sales sensing device for an ice cream vending machine that can accurately return a sensing rod without a separate spring in view of the above-described conventional problems, and has a very simple configuration regardless of the number of sales outlets.

In order to achieve the above object, the sales detection device for an ice cream vending machine according to the present invention is a sales detection device for an ice cream vending machine for selectively driving and stopping a corresponding driving motor by sensing the operation of a piston by a plurality of sales levers, respectively. And a plurality of sensing levers rotatably supported on the hinge shafts corresponding to the plurality of sales openings of the main body, the sensing levers of which the tip of the sensing rod contacts the upper end of the corresponding piston, respectively, And a plurality of micro switches fixed to the sales outlet to control the corresponding motors, and a plurality of pushers fixed to the respective sensing levers to selectively contact the micro switches.

According to one preferred feature of the present invention, the main body further comprises a stopper of an appropriate height installed in parallel with the hinge axis, and a plurality of engaging protrusions extending to the rear end of each sensing lever to selectively contact the stopper.

Accordingly, the present invention, since the detection lever is returned to its initial state by its own weight in accordance with the return of the piston by the sales lever even without a separate spring, it has a great effect on the safety and reliability of the use of the ice cream vending machine and the improvement of manufacturability.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings, in which portions not shown will be described with reference to FIG. 1.

In Figure 3, the sales detection device of the ice cream vending machine according to the present invention, the support plate 11 is fixed to the front plate of the body (B), the hinge shaft (hinge) at approximately intermediate positions of the support plate 11 is spaced at an appropriate interval therefrom shaft 12) is fixed in the horizontal direction. Under the hinge shaft 12, the support plate 11 is provided with a plurality of micro switches 13 for controlling the motor M of the sales outlet corresponding to each ice cream sales outlet of the main body B, respectively.

At a predetermined position of the hinge shaft 12, a plurality of sensing levers for selectively detecting the operation of the piston P by the sales lever L of each sales outlet of the main body B to selectively contact the corresponding microswitch 13 14 is rotatably supported. Since the detection lever 14 should be able to rotate about the hinge shaft 12 as the piston P rises, the hinge shaft 12 is preferably located inward of the piston P.

The sensing lever 14 includes a boss 15 rotatably inserting the hinge shaft 12 and a sensing rod 16 extending downward of the boss 15 to contact the upper end of the corresponding piston P. And an engaging protrusion 17 extending to the opposite side of the sensing rod 16 to prevent excessive rotation of the sensing lever 14 by the piston P. As a result, a stopper (19) contacting the engaging protrusion 17 of each sensing lever 14 is formed on the support plate 11 to the upper side of the hinge shaft 12 so as to protrude along the hinge shaft 12 at an appropriate length. The protruding length is preferably set such that the sensing lever 14 can be returned by its own weight after being rotated by the piston P.

On the other hand, on the outer circumference of the boss 15 of each sensing lever 14, a pusher 18 for selectively contacting the corresponding micro switch 13 is installed at an appropriate angle so as to be positioned inside the sensing rod 16.

The operation of the sales detecting apparatus according to the present invention configured as described above will be described with reference to FIG.

In FIG. 4, (a) is positioned at a position where each piston P closes the outlet O of the cap A in a state of being stopped, and each pusher 18 corresponds to the micro switch 13 of the outlet. ), The micro switch 13 is closed. In this state, when the seller pulls the sales lever L to sell the ice cream, as shown in (b), the piston P rises along the cylinder C so that the outlet O of the cap A is closed. Open. At the same time, the sensing lever 14 is rotated upward with respect to the hinge shaft 12 by the sensing rod 16 contacting the upper end of the piston P, so that the pusher 18 is rotated at the same time. The micro switch 13 is opened by falling. Accordingly, the motor (M) is driven to rotate the feed screw (S) is to be sold through the outlet (O) ice cream. At this time, the rotation of the sensing lever 14 is appropriately regulated by the engaging projection 17 contacting the stopper 19 of the support plate 11.

When the next seller returns the sales lever L to the initial state, as shown in (a), the piston P descends to close the outlet O, and at the same time, the detection lever 14 is driven by its own weight. It rotates downward about the hinge axis 12. Accordingly, the pusher 18 is rotated together with the sensing lever 14 to contact the micro switch 13 so that the micro switch 13 is closed. As a result, the driving of the motor M is stopped, and thus the transfer screw S is stopped to be in a suspended state.

As described above, according to the present invention, the sensing lever is automatically returned to its initial state by its own weight without a separate return means, and a plurality of sensing levers have a very simple configuration supported by one hinge shaft, thereby making it easy to reduce the number of parts. I can make it. In addition, since there is no fear of return failure of the detection lever, the failure rate of the vending machine is significantly reduced. Therefore, the present invention has a very excellent effect of greatly improving the safety and reliability of the use of the ice cream vending machine and manufacturability.
