Description

A BUCKET CONVEYOR BACKGROUND OF THE INVENTION a. Field of the Invention This invention relates to a bucket conveyor, and more particularly to a bucket conveyor for collecting medals, coins, medallions or the like (hereinafter merely referred to as medals, coins or the like) and delivering them to coin exchanging machines, automatic coin exchanging machines, ticket selling machines, game machines, ball issuance machines, and medal issuance machines.

b. Background Art In many pin ball game shops of various types, there are disposed, in an array of pin ball game machines aligned in a lengthwise direction called an "island", ball issuance machines or medallion issuance machines alongside the pin ball game stands. At one end of the island is usually disposed a container(s) for recovering medals or coins or the like, for example, a safe. There is further provided a bucket conveyor for supplying coins or medals to the abovementioned coin exchanging and ball issuance machines or medallion issuance machine(s).

More illustratively, a belt conveyor is disposed behind the pin ball game stands. The belt conveyor receives thereon medals or coins from the coin exchanging and ball issuance machines or medal issuance machines which have been thrown therein by players in the island and transfers them to the end of the island where they are accumulated in the container.

There sometimes arises shortage of medals or coins in these coin exchanging and ball issuance machines or medal issuance machines. For this reason, means for replenishing such shortage, for example, bucket conveyors, are provided to supply medals or coins.

Bucket conveyors of the conventional type for the purpose of recovering coins has a plurality of buckets 4 opened outward, as shown in Fig.1. In this connection, it is to be noted that the shape of the coins or medals used for this purpose is flat as different from balls such as those used for pin ball game which are freely rotatable under its weight due to the gravity, and such coins or medals are required to be forcibly transferred by way of a belt conveyor 2 or the like. In a kind of bucket conveyor 1 which brings up medals or coins in vertical direction, medals or coins are likely to fall into a gap at the inlet and be clamped between some members of the conveyor and apt to lock the bucket at the position, thereby resulting in damage to the conveyor or to the motor which drives the conveyor.This gives a serious influence on the operation of the bucket conveyor 1 for bringing up the coins or medals.

A bucket conveyor for conveying game balls is disclosed by Japanese examined Patent Publication for Opposition (Kokoku) No.54-26935 and is well known, in which an endless chain consisting of a number of links each consisting of a pair of link plates being opposed parallel, one at one side and the other at another side and each carries a bucket fixed thereto and the entire endless bucket conveyor is driven between an upper sprocket and a lower sprocket, and a group of buckets carried by link plates at one side convey game balls became dirty, while the other group of buckets carried by the link plates at another side convey polished balls.

However, the above-mentioned bucket conveyor is very complicated in construction, since each link constituting a loop consists of a pair of link plates or wheels and is attached with a fixing piece for carrying a discrete bucket, so it requires many parts and many steps for assembling them, increasing the manufacturing cost of the conveyor.

It is also well known such type of bucket lifting machine which comprises a plurality of buckets coupled through hinged coupling members and carries balls or medals from a lower position to an upper position, as disclosed by Japanese Patent examined Publication for Opposition (Kokoku) 54-42151.

However, since the opened mouth of the buckets of this conveyor is directed outward and the buckets are positioned inside, it is very difficult to receive medals or coins into the bucket through the opened mouth, and moreover, since the buckets are driven by a engageable rod attached to a rotary drum, the entire construction of the conveyor becomes inevitably complicated, consequently medals or coins are liable to be clamped during transportation between the engageable rod of the lower drum and the bucket, thereby it results in damage to the clamped coins or medals and further there arises misfitting between the rod of the upper drum and the bucket and thereby brings about unsteady function of the entire conveyor.Japanese Patent No.32118 is known as one directed to an automatic grain feeding machine for conveying grains from lower side portion to upper side portion by a plurality of box-like buckets each one of them is formed as a container being closed at its rear part in the direction of its ascending movement and these buckets are connected together with the opened mouth being directed inward to constitute a ring. However, since this machine comprises supporting pieces for mounting each bucket on the seat of the supporting piece through a pin(s) and is attached to two parallel belts, it is also complicated in construction and requires, large number of material, long time for mounting the buckets, many steps of assembly and high costs.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks encountered in the conventional conveyors, the present invention aims to obviate aforesaid problems and to provide a bucket conveyor capable of performing recovery and taking up of medals, coins or the like smoothly, in large number and with high extent of efficiency, but without accompanying any clamping or any possible damage to the medal or coins being handled during the conveying work, and yet more simple in construction, with less number of parts, less assembling steps, with less amount of material and lower cost.

The bucket conveyor of this invention comprises: a plurality of buckets each of which is formed as a boxlike container with its opened mouth being directed to the inside of the conveyor and a pair of rims on the upper end of the opposing sides of said opened mouth are provided with a set of coupling member through which one bucket is coupled to other adjacent buckets one by one to constitute a loop of buckets and the rear end of each bucket in the direction of ascending movement is formed as a bottom of a container;; a pair of sprockets one located at the upper position and the other at the lower position, each of said sprocket consisting of a pair of sprocket plates being opposed with each other with space or gap the length of which is made sufficient to receive therein the opened mouth of said bucket, and each having a plurality of recesses formed on its outer periphery to receive therein said coupling member, wherein:: according to a first embodiment, each of said sprocket plate is formed as a planar plate excepting the recesses and two sheets of the sprocket plates are placed being coaxially opposed with each other to constitute a sprocket assembly, and the pair of sprockets are disposed in such a manner that one at the upper position and the other at the lower position, and the portion of the opened mouth of the body of said bucket is interposed between said opposing sprocket plates with least clearance and the coupling members of each bucket is received in and rests on a recess one after another as the buckets are driven in an endless manner.

In the second embodiment, a single sprocket is disposed either as an upper sprocket or as a lower sprocket and said sprocket plates are formed as a planar plate excepting the recesses and two sheets of the sprocket plates are placed being coaxially opposed with each other to constitute a sprocket assembly, and a pair of rail are attached to the sprocket and are extended between the sprocket and the portion opposite to said sprocket, and each of the buckets is provided with a pair of rollers each disposed at one axial end of the coupling piece, so that each bucket can conveyed with the rollers rolling over the pair of rails.

BRIEF DESCRIPTION OF THE DRAWINGS Fig.1 is a shematic front view showing a conventional bucket conveyor; Fig.2 is a partly fragmented schematic front view showing an embodiment of the present invention; Fig.3 is a side view of the bucket conveyor shown in Fig.2; and - Fig.4 is a perspective view showing the way of coupling adgacent two buckets together and Fig.5 is a perspective view showing another embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Explanation will now be made in detail by referring to the accompanying drawings. In FIg.l and 2, bucket conveyor 5 comprises a plurality of box-like buckets 6 having a cross, sectional shape almost alike a parallerogram and each of its two opposing side faces is formed as a parallerogram, so that the rear part 6a of the bucket in the assending direction inclines downward, that is, the bottom of the bucket opposite to the opened mouth inclines downward in the ascending direction, and the upper edge of the two remaining side faces defining the opened mouth 7 of the bucket 6 are attached with hinge type coupling members 8, 9a and 9b mating with the coupling member of adjacent bucket.

A pair of sprockets 11 and 12 are disposed at an upper and a lower position, respectively, which rotate and support the buckets 6 in upright state and make them to travel around the sprockets 11 and 12 as an endless conveyor. The sprocket at the upper side consists of a pair of coaxially disposed parallel sprocket plates or wheels lia and lib, similarly the sprocket 12 at the lower side consists of a pair of coaxially and parallely dispose sprocket plates or wheels 12a and 12b, and each of these sprocket wheels lla, llb, 12a and 12b are provided with a plurality of recesses 13 around the outer peripheral face and the space defined between the wheels lea and lib and that between 12a and 12b, respectively, is kept to form a gap having a width to allows the bucket 6 to fit in the gap so that the opened mouth 7 of the bucket can be placed in the gap, and the upper sprocket il is provided with a motor for driving the conveyor.

Moreover, the opened mouths 7 of the plurality of buckets being in engagement with the upper sprocket 11 and the lower sprockets 12 are placed in the gap or space defined between the two opposing wheels 11a and lib, and between 12a and 12b, and both axial ends of each pin 10 for coupling two adjacent buckets one after another (refer to Fig.4) are engaged with the recesses 13 of the plates or wheels lla, llb, 12a and 12b. A trough 14, for receiving medals or coins 16 having been carried upward by the bucket 6, is disposed under the sprocket 11 and covers the width of the gap between the wheels 11a and llb, and a chute 15 for introducing medals or coins, is disposed above the sprocket 12 and cover the width of the gap between the wheels 12a and 12b.The box-like bucket 6 has, as shown in Fig.4, an opened mouth 7 one end rim of which in the direction of travel has a central hinge 8 and the other end rim opposing the central rim has a pair of end hinge pieces 9a and 9b at its both lengthwise ends and the gap between the hinge pieces 9a and 9b has a width able to receive the central hinge 8.Two adjacent buckets 6 can be coupled together being allowed free swing motion by fitting the central hinge 8 of one bucket 6 in the gap between the pair of hinge pieces 9a and 9b of the other bucket 6 and then inserting a pin 10 passing through these members 8, 9a and 9b and yet both tip ends of the pin 10 project beyond the axially outer most end of each hinge pieces 9a and 9b, thereby hinge coupling are completed on the opposing sides of the opened mouth 7 of the bucket 6 and the adjacent buckets are coupled one by one and the projected both ends at respective hinge coupling portion can engage with and rest on the plurality of recesses formed on the outer periphery of the sprockets 11 and 12.

A bucket conveyor 5 assembled as a continuous loop by coupling a plurality of buckets 6 through respective coupling hinge member, is completed by way of coupling the central hinge 8 formed on one rim of the opened mouth 7 of one bucket 6 with the hinge pieces 9a and 9b formed on the rim of the other bucket 6 and by inserting the pin 10, through these members and this way of hinge coupling is made with least clearance between each hinge members.

Explanation will be made next on the manner of operation and the function of the above-mentioned embodiment.

Medals or coins 16 introduced through the feed chute 15 are received through the gap between the two opposing plates or wheels 12a and 12b of the lower sprocket 12 then into the opened mouth 7 of the bucket or bucket 6 just being under the chute 15 and finally into the body of the bucket type container. The trained buckets in the advancing stroke move upward one by one by the rotation of the upper sprocket 11 driven by a driving means (not shown) and through the pins 10 engaging with the plurality of recesses 13.Since each bucket 6 is formed as a container, the rear part of which in the direction of advancing movement inclines downwards, there is no fear that the medals or coins in the bucket 6 run away outside the bucket 6 even in its vertical upward travel after it has received the medals or coins from the chute and all the medals or coins 16 contained in-the bucket 6 at its lowermost position are carried upward to the top of the upper sprocket 11 with no loss of medals or coins due to the escape of the loaded medals or coins.

Upon arrival of the bucket 6 at the top of the upper sprocket 11, the opened mouth 7 of the bucket 6 is turned downward thereby allowing all the medals or coins 16 in the bucket to run away from the bucket 6 down to the receiving trough 14 through the gap between the opposing plates of the sprocket 11 and finally to the spot where they are desired to be delivered.

As an alternative means, it is also possible to make the hinge pieces of the bucket, instead of the pin, engage the recesses on the outer periphery of the sprocket.

As a second embodiment of the present invention, a bucket conveyor 17 in which each coupling pin 19 couples adjacent bucket 18, is provided with a pair of rollers 20a and 20b, at its both lengthwise ends, as shown in Fig.5, and a pair of rails 22a and 22b are attached to the sprocket which can be installed alone either as an upper sprocket 11 or as a lower sprocket and is extended around the sprocket 11 or 12 and to the portion opposite to the sprocket, so that each bucket can be smoothly driven with its roller rolling over the rains 22a and 22b, in addition, each of the rails can further be attached with a flange 23a or 23b, respectively, namely two side flanges per one rail (not shown) can be provided to prevent the rollers 20a and 20b from derailing As explained heretofore, the bucket conveyor of the present invention comprises coupling members formed on the upper rims of the two opposing sides of the opened mouth of a box-like bucket having a bottom at the rear portion in the direction of upward movement, and the opened mouth of the bucket being disposed directed to inside of the container and a plurality of buckets are coupled together one by one as a loop through the coupling members.

Each of pair of sprockets, an upper sprocket and a lower sprocket, consists of a pair of sprocket plates or wheels having a plurality of peripheral recesses and being coaxially and parallely disposed in such a manner that the gap between these sprocket wheels can receive the bucket, and since the sprockets are disposed one at the upper position and the other at the lower position and the buckets assembled into a loop is extended between and around the two sprockets and the coupling members of the bucket are received and can rest on the recesses.

In addition, the body of the buckets and the sprockets are coupled with least clearance, and in the second embodiment the buckets can roll over the endless rails. By virtue of these features, the bucket conveyor of the present invention is very suitable for collecting and delivering articles such as medals or coins to be used for ball games, because there is no fear that such medal or coins being clamped or running away from the bucket and thus resulting in deformation of the conveyed articles or causing damage to the driving means and, as a consequence, the bucket conveyor of this invention is able to smoothly collect the articles with no fear of loss due to escaping of the medals or the like during conveying, and it is also possible to collect and transfer a large number of medals or coins with high efficiency and deliver them to the place where they are desired to be replenished, and thereby the function of such collecting and delivering system for such medals or the like can be leveled up. IN addition, by attaching a pair of endless rails, such undesirable rolling or swing motion of the bucket on their halfway between the upper sprockets and lower sprocket as encountered in two sprocket type mean which is liable to result in escaping of the coins or the like during transportation can be eliminated.

Although the present invention has been disclosed by referring to the detailed description, embodiments and the accompanying drawings, it will be appreciated that the technical concept of the present invention is not limited to those described in the specification and any other modification can be made within the sope but without deviating from the spirit of the present invention.
