Title:
ROTARY DRUM COIN STACKING AND DISPENSING DEVICE
United States Patent 3703903


Abstract:
A coin dispensing mechanism comprising a plurality of coin dispensing stations, each station including a rotary drum having a circumferential flanged edge containing a plurality of holes mounted within a stationary wheel having a circumferential overhanging portion which forms a circumferential slot with the flanged edge of the rotary drum. The drum will rotate through a reservoir of coins during which coins will drop through the holes and into the circumferential slot. The coins will then be engaged by pins mounted on the outside of the flanged edge of the drum and transported through the circumferential slot until they come in contact with a coin chute located at the top of the drum into which they are deposited. When the coin chute is full, the drum will stop.

Description:
BACKGROUND OF THE INVENTION:

The present invention is directed to a mechanism for dispensing coins which is located within a checkout counter. In the checkout operation, an optical reader unit is used to read tags located on the merchandise and to operate a data collecting device which computes the total cost. This arrangement measurably increases the speed of the check-out operation of the merchandise. As a result, there is a need for a coin dispenser which will always be in condition to provide change and which can be quickly and easily loaded with coins for dispensing.

SUMMARY OF THE INVENTION

It is an object of this invention to provide a coin dispenser which will be easy to load and will be in condition to dispense coins as long as there are coins in the coin-hopper.

It is another object of this invention to provide a change dispenser which is capable of receiving coins in bulk for loading and which will quickly transport the coins to a coin chute for dispensing therefrom. In order to carry out these objects, there is provided a coin dispenser comprising a plurality of sensing stations, each composed of a rotary drum mounted within a stationary wheel, the drum and the wheel having co-extending circumferential flange portions forming a slot, a plurality of holes located in the flange portion of the drum and abutting means mounted on the outside of the flange portion of the drum adjacent to each of the holes. A coin hopper adapted to receive coins in bulk form is mounted adjacent to the rotating drum and is in communication with the bottom of the drum. As the drum rotates, coins will drop through the holes to be engaged and carried by the abutting means through the circumferential slot to a coin chute located at the top of the drum. Coins located in the coin chute are dispensed by operation of a gate located in the chute.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention is directed to a change dispenser for dispensing coins as change as a result of a merchandise transaction. The change dispenser comprises five coins dispensing mechanisms, each of which dispenses a single coin denomination. Since each coin dispensing mechanism is of the same construction, the present description will be limited to a single dispensing mechanism.

Referring to FIGS. 1 and 2, there is shown a typical coin dispensing mechanism utilized in the change dispenser. The mechanism includes a stationary disc member 20 to which is attached to open-ended coin hopper 21. The disc 20 has a slot 22 into which coins 23, located in the hopper, will fall through. The disc 20 has also a circumferential flange portion 24. Secured to the disc member 20 is a bushing 25, within which is positioned a pair of bearings 26 rotatably supporting one end of a drive shaft 27 operated by a motor 28.

Connected to the drive shaft 27 by means of a slip clutch 30 is a drum member 31 having a circumferential flange portion 32, within which are located a plurality of holes 33 (FIG. 3) large enough for one of the coins 23 to drop through. The drum member 31 is positioned within the flange portion 24 of the disc 20. Mounted adjacent to and downstream of each of the holes 33 on the outside of the flange portion 32 are a pair of pin members 34. As shown in FIG. 2, the pin members 34 are located in a circumferential slot formed by the flange portion 24 of the disc 20 and the flange portion 32 of the drum member 31.

Located in the flange portion 24 on the top side of the disc member 20 is a slot 35 (FIG. 4) within which is located an elongated center portion 36 of the flange portion 24. Mounted within the slot 35 is one end of a coin chute 37 which is attached to the disc member 20 by means of studs 38. A bottom portion 40 of the chute 37 extends within a slot 41 (FIG. 2) located in the center of the flange portion 32 of the rotating drum. At the bottom of the chute 37 is a gate member 42 mounted on the armature 43 of a solenoid 44. Located beneath the end of the chute 37 is a coin receptacle 45.

In the operation of the change dispenser, the operator will load the hopper 21 of each coin dispenser with coins of one denomination. The motor 28 will then operate, thereby rotating the drum 31 in a clockwise direction as viewed in FIG. 1. As the drum rotates, coins 23 will fall from the coin hopper 21 by means of gravity through the slot 22 in the disc 20 to the inside of the flange portion 32 of the rotating drum 31, where they will then fall through the holes 33 into the slot formed by the flanges of the disc 20 and the drum 31. The coins will then be engaged by the pins 34 and carried by the movement of the drum to the top of the disc 20 where they will be guided into the coin chute 37 by the bottom portion 40 of the coin chute. As the coins fill up the coin chute, there will be reached a point where the last coin in the coin chute will engage a coin carried by the pins on the rotating drums which will result in the stopping of the drum. The drum 31 will then slip on the drive shaft 27 due to the action of the slip clutch 30. Whenever change is to be dispensed, the solenoid 44 will be energized, thus withdrawing the gate 42 from the coin chute 37 allowing the proper number of coins to drop from the coin chute into the coin receptacle 45. After the proper number of coins have been dispensed, the solenoid will be de-energized to move the gate back into the chute. As the coins are dispensed from the chute, the drum 31 will be released to rotate to feed new coins into the coin chute until the gate is returned to its blocking position. It will thus be seen from this construction that the coin chute will always be filled with coins until the supply of coins in the coin hopper 21 is exhausted. When this occurs, the operator can easily fill the hopper with coins.

While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and detail may be made therein without departing from the sphere and scope of this invention.
