9 Claims, 7 Drawing Figures COIN CIRCULATING FEED CONVEYOR BACKGROUND OF THE INVENTION This invention is in the field of supply conveyors and particularly the field of conveyors for supplying coins to coin processing machines.
Many business enterprises involve the handling of a great number of coins necessitating sorting, counting, separating and wrapping coins in accordance with their denomination. In a great number of instances, the bulk of coins to be handled is very large, and many of the processes, for example, counting and wrapping coins of the same denomination, necessitates the use of a multiplicity of machines and the supply of coins thereto has presented problems. It is important that each machine of a group be constantly supplied with sufficient coins to keep it operating at maximum efficiency.
SUMMARY OF THE INVENTION The present invention may be summarized by pointing out that the apparatus involved comprises means for constantly circulating a mass of coins in sufficient quantity to maintain an adequate supply at the entrance of each of the machines to be fed. In general, the invention comprises a circulating conveyor arrangement that constantly circulates a mass of coins around a closed path along which directing means are provided for directing coins from the path to the respective processing machines so that an excess of coins is always available at the entrance to each processing machine.

FIG. 7 is a view similar to FIG. 6 taken on the line 7-7 of FIG. 1.
DESCRIPTION OF A PREFERRED EMBODIMENT In FIG. 1, numeral 2 indicates a supply hopper that may be filled with coins at some remote location, then transported to the apparatus shown and placed on a suitable holder 4 for directing coins to an elevating conveyor 6. The elevating conveyor 6 discharges elevated coins, through a suitable chute 8 onto the conveyor arrangement 10 of the present invention. The conveyor 10 distributes the coins to each of a plurality of coin processing machines 12, only schematically shown in the drawings. The machines 12 shown in the drawings are coin counting and wrapping machines. For purpose of illustration only, it is assumed that all of the coins are of the same denomination and the machines 12 arrange the coins in stacked order, count predetermined numbers of coins and wraps each counted group of coins into a single package. The details of construction and/or operation of the coin wrappers 12 will not be described since they comprise no essential part of the present invention. It is to be noted that the conveyor system 10 is supported on suitable uprights or standards 14 to extend over the supply hoppers 16 of machines 12 and suitable chutes 18 or the like direct coins from the conveyor system 10 into the hoppers 16.
Referring now to FIG. 3, the conveyor system 10 comprises a pair ofendless conveyor belts 20 and 22. Each belt is trained over a small roller 24 at one end and over a larger diameter roller 26 at its other end. Suitable motors 28 (see FIGS. 1 and 4) are arranged to drive the respective belts so that their upper runs move in opposite directions, as will be described, coins delivered to the conveyor system through chute 8 are carried in one direction by one of the belts, then transferred to the other belt and moved in the opposite direction along generally parallel paths. As the coins reach the starting end of the apparatus on the second belt, they are again transferred to the first belt for recirculation. Arranged between the two parallel paths are openings 30 in a guiding wall, to be described, whereby coins travelling along the parallel paths may drop into the chutes 18 for flow to the respective processing machines 12.
Referring now to FIGS. 4-7, the conveyor system 10 comprises a framework defining an upstanding inverted V-shaped central member comprising outwardly and downwardly sloping side walls 32, which are shown arranged at right angles to each other and defining an uppermost generally horizontal crest or ridge 34, in the form of a relatively sharp apex. The framework includes upwardly and outwardly extending bottom walls 36 and outermost walls 38 parallel to the sloping walls 32. Each of the outer walls 38 terminates in an upwardly extending flange portion 40. It will thus be seen that the walls 32, 36, and 38 define generally upwardly facing channels and the conveyor belts 20 and 22 along with their rollers 24 and 26 are arranged to operate within those channels. As is apparent from FIG. 4, the larger diameter rollers 26 are of such diameter that the outer peripheries of the belts thereon are substantially tangent to the wall 32 of the opposite channel whereas the rolls 24 are of much smaller diameter. Thus, the upper run of each conveyor belt 20 and 22 extends from a lower level at one end of the apparatus to a higher level at the other end, the higher level being at least as high as the crest 34 previously referred to. The lower runs of the belts extend and run along the bottom walls 36. In this manner coins deposited on the upper run of either belt will be carried thereby in an upwardly sloping path to one end of the apparatus where they can slide laterally off that belt over the crest 34 and onto the lower end of the upper run of the other belt for movement in the opposite direction.
The above-described function is repeated at the other end of the apparatus and thus coins remaining on the belt are continuously circulated along the walls 32. It is to be noted that the coin carrying surfaces of the belts 20 and 22 slope toward the walls 32, at substantially right angles thereto, and thus all coins on the belts gravitate toward the. walls 32.
FIG. 5 illustrates schematically the structure at each end of the apparatus wherein an outer end wall 42 closes the ends of the channels formed between walls 32 and 38 and flanges 40, then extends inwardly to define the top wall 44 of a housing enclosing the ends of the conveyor belts. An inner downwardly extending wall portion 46 defines the terminal ends of the channels along which coins are moved and as shown in FIGS. 4 and 5, the wall 46 extends downwardly into close proximity to the upper surfaces of the belts 20 and 22. The belts move under the edges of the wall 46 and in such close proximity thereto that coins cannot pass thereunder. As is clear from FIG. 5, coins moving to the right on the upper belt shown in that figure will impinge the wall 46 and be directed thereby laterally of and over the crest 34 to gravitate downwardly onto the lower end of the belt in the other channel to thus reverse the flow of coins.
As shown in FIGS. 3, 6 and 7, upstanding flanges defining a divider wall 48 extend upwardly from the crest 34 throughout the major length thereof but the wall 48 terminates in opposite ends 50 (see FIG. 3) at positions spaced inwardly from the end walls 46. The divider wall 48, however, extends past the endmost openings 30. Thus, the upstanding wall or divider 48 prevents movement of the coins from one channel to the other except at the ends of the apparatus.
FIG. 7 shows one pair of openings 30 for receiving and directing coins into a chute 18 leading to one of the hoppers 16. While not shown in FIG. 7, it is to be understood that coins are supplied to the conveyor system in such quantity that the chutes 18 and hoppers 16 will be maintained full of coins at all times and those coins unable to enter an opening 30 because of the mass of coins therebelow are merely carried past that respective opening 30 to be available at succeeding openings as the circulating coins move therepast. It is to be noted that the openings 30 are arranged in pairs directly opposite each other in the walls 32 so that coins may enter any chute 18 from either of the conveyor channels.
As is also apparent from FIGS. 4, 6 and 7, the channels defined by walls 32, 36 and 38 are provided with interior transverse walls 52 arranged to slidably support the upper runs of the belts 20 and-22.
While a single specific embodiment of the invention has been disclosed herein, it is to be understood that other embodiments may be resorted to within the scope of the appended claims. For example, a single conveyor belt could be employed with suitable roller means at the ends of the apparatus to direct the belt from one channel of the apparatus into the other channel for movement in the reverse direction. Furthermore, other conveying instrumentalities, other than endless belts, might be employed to move coins along the channels. While the apparatus has been constructed with reference to forwarding coins of the same denomination to counting and wrapping machines, the same is merely illustrative of the invention and it is to be understood that even coins of random denomination could be thus directed to a plurality of machines for processing the coins in some other manner.
