Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is a device for transporting a large number of coins from a low position to a high place using a bucket cart. This invention relates to a bucket reversing mechanism in an automatic coin feeding device that drops coins into a chute and supplies them through the chute.

(Prior Art) Conventionally, a wide variety of automatic coin feeding devices using buckets have been developed, and one with a structure using an endless belt and wire has been proposed.
A widely used device using the endless belt has a mechanism in which coins fall to the opposite side when the bucket is turned over at the top, and a structure using a wire is disclosed in Japanese Utility Model Application Publication No. 57-42469. A publication has been proposed, and the claims are set forth below.

At the lower level, a bucket loaded with coins is raised by an elevating means, and at the upper level, the bucket is reversed by a guide means to drop the coins from the bucket to a receiving chute, which is provided between the receiving chute and a branch chute connected thereto. A bucket type coin supply device in which a sorting shutter is operated by an electric drive means to supply coins dropped into a receiving chute to a predetermined branching chute, the bucket being interlocked with reversal of the bucket by the guide means,
A bucket-type coin supply device comprising a locking means for locking the sorting shutter operated when the electric drive means is turned on.

(Problem to be solved by the invention) However, among the conventional techniques described above, the bucket structure of the endless belt that reverses at the top is such that the coins fall on the opposite side, so there is a problem between the bucket and the conveyance frame. If the coin falls through the required gap provided, and if the gap is reduced, the bucket may come into contact with the frame due to the bending of the endless belt, causing noise or even damage. The number of parts increases because the buckets must be installed at equal intervals, and in the case of structures using wire, rollers protruding from the sides of the buckets fit into the guide grooves of the block fixed to the guide. It is guided along the groove, reversed and discharged, but it is a mechanism that fits into the guide groove of the block, so if it swings during lifting due to the weight inside the bucket, it will not fit into the guide groove and will stop at the block. There was also the problem that the curved guide groove did not follow smoothly. Therefore, since the reversing structure is complicated, there was a problem in that it took time and effort to repair.

This idea was devised in view of the above circumstances.
A motor for raising and lowering the bucket is installed on the back of the central part of the vertically installed frame, and a chute that opens on the upper side is fixed, and an upper locking part with a long side and an obliquely bent upper locking part and a lower part are attached to the upper side of the opening of the chute. A lower locking portion bent into a short side shape is provided on the side, and when the bucket is moved up and down by the drive of the motor, a guide roller provided above the rear portion of the bucket comes into contact with the upper locking portion, and the roll is stopped. When the chute moves, the bucket flips sideways into the chute and coins are thrown in. When the motor drives in reverse, the bucket starts to descend, and when the guide roller comes into contact with the lower locking part and rolls, it returns to its original position. It is an object of the present invention to provide a bucket reversing mechanism in an automatic coin feeding device that is capable of returning to its original state.

(Means for solving the problem) The collected coins are stored in a bucket at a specific location at a low position, raised to a high place by a lifting means, and the bucket is reversed by an upper limit switch and a guide means provided at a high place. In a coin feeding device that drops stored coins into a chute, then lowers the bucket by the elevating means and stops by a lower limit switch, a frame is erected, and the bucket is raised and lowered from the central part of the back of the frame. A wire is attached to the motor, and the wire is fixed to a pedestal via a pulley at the tip of the frame.The pedestal has rollers fixed to its upper and lower ends, and a reversing shaft installed near the center allows the bucket to be rotated. is rotatably mounted, a bucket holder and an angle stop plate are provided adjacent to the lower center, a bucket holder for storing coins is provided on the front of the holder, and a bucket holder is provided on the side of the frame that protrudes from the front parallel to the rail. A guide plate is provided, and a guide roller provided above the rear of the bucket rises as the wire rises, and a guide plate is provided with a long side and diagonally above the opening of the chute provided in the side of the frame. When the guide roller comes into contact with the bent upper locking portion and rolls, the bucket is reversed via the reversing shaft, allowing the stored coins to fall into the chute, stopping the reversing at the angle stop plate, and causing the motor to When the bucket cart is lowered by the reverse drive of A bucket reversing mechanism in an automatic coin feeder, characterized by:

(Function) The function of the bucket reversing mechanism in the coin automatic feeder of the present invention configured as described above is that the lifting speed of the bucket and the standby time of the bucket at the lowest position are set in the control box. After waiting for the set time, the motor will start and start rising. When the guide roller installed above the rear of the elevated bucket cart comes into contact with the upper locking part and rolls, the bucket cart gradually tilts sideways via the reversing shaft of the pedestal, and when rotated approximately 90 degrees, the angle changes. stopped by a stop plate,
The pedestal on which the bucket is attached rises further,
When the switch actuator contacts the upper limit switch, the motor reverses and the pedestal lowers. When the guide roller comes into contact with the lower locking part of the bucket that has been tilted as the pedestal descends, the bucket that has been tilted as the pedestal descends gradually returns to its original position, and then descends in the restored state and engages the switch actuator. The technical problem was solved by making the motor turn off when the bucket touches the lower limit switch, and the bucket goes into standby mode until a set time, repeating the operations in sequence.
