Abstract

An automatic dispensing device for products is provided, and includes a warehouse with a back guide, a front guide, and an intermediate movable guide so as to define product chutes arranged one behind the other. Each chute is adapted to hold a plurality of products, one stacked upon the other. An inclined ramp is provided at the lower end of the product chutes for receiving the products from the chutes. The movable guide is movable between lowered and raised positions to control which chute is in communication with the ramp so that products from only one chute are in communication with the ramp at a given time. A control element is provided on the ramp for automatically releasing one product at a time from the ramp.

Claims

1. An automatic dispensing device for products, comprising:

a warehouse having opposite side walls, a back guide, a front guide, and at least one movable guide between the front and back guide, said guides being substantially vertically oriented so as to define substantially vertical product chutes arranged one behind another, each chute having a lower outlet end being adapted to hold products stacked one upon another;

an inclined ramp at the lower end of the product chutes for receiving products from the chutes;

said movable guide being movable between a lowered position, wherein communication is prevented between the ramp and the chute behind the movable guide, and a raised position wherein communication is provided between the ramp and the chute behind the movable guide such that products are released on to the chute;

control means on the ramp for automatically releasing one product at a time from the ramp; and

power means for selectively moving the movable guide between said lowered and raised positions such that only one chute is in communication with the ramp at any time.

2. The device according to claim 1, wherein the control means consists of a star-shaped part presenting a series of peripheral stop notches being rotatably mounted on a central pin and a sliding plunger for acting on said star-shaped part in first and second positions, said plunger having a first means for maintaining the star-shaped part in a normal stop position when in said first position and a second means to rotate the star-shaped part by one notch causing the release of one product unit and to block the passing of the next product when the plunger is in said second position.

3. The device of claim 1 further comprising means for adjustably mounting said front guide and movable guide between said side walls so that the spacing between said front guide, movable guide and back guide is adjustable to accommodate various sized products.

4. The device of claim 1 wherein said movable guide includes an extendable and retractable extension member operatively connected to the power means for raising and lowering with respect to the outlet end of the chutes.

5. The device of claim 1 wherein said control means includes a movable star-shaped element being rotatably mounted on a central pin, and having a series of peripheral notches for engaging one product to prevent the release of said product.

6. The device of claim 5 wherein said control means further comprises a sliding plunger having means for normally maintaining the star-shaped element in a stop position and for periodically rotating the element by one notch to release one product and block the release of the next product.

7. The device of claim 1 further comprising sensing means for sensing the presence and absence of product on the ramp.

8. The device of claim 7 wherein the sensing means is operatively connected to the power means whereby upon sensing an absence of products on the ramp by the sensing means, the power means is actuated to raise the movable guide so as to provide communication between a product-containing chute behind the movable guide and the ramp.

9. The device of claim 8 wherein the movable guide includes a projection extending forwardly into the forwardly adjacent chute, the projection being adapted to support additional products loaded into the chute when the movable guide is raised and the rearward adjacent chute is in communication with the ramp.

10. The device of claim 9 wherein the projection extends from the movable guide at an angle corresponding to the angle of the ramp such that when the movable guide is lowered, the projection lies substantially flat upon the ramp.
