Description

[Detailed description of the invention] (Field of industrial application) This invention transports medals and coins supplied from a collection lane to a low-position hopper to a high place using a bucket, and then returns the medals and coins to a high place in a predetermined position. This invention relates to a bucket-type medal transport device that opens an opening/closing lid provided at the bottom, drops the medals to the supply side, and supplies them to a supply lane or the like via a chute or the like.

(Prior art) Conventionally, a reversible medal transport device using a bucket has a mechanism in which the bucket is reversed when the bucket reaches the top using a wire winding method, and the medals fall downward from the bucket. Many things are used.

However, the medal conveyance device with such a mechanism,
When the bucket is turned over, medals may be thrown out and scattered, and medals may fall between the bucket and the transport frame. Contact may cause noise, or because the bucket is suspended by a wire, if the folding bucket that hangs the bucket gets caught when fitting with the rail, the wire may become loose, and sometimes it may malfunction or be damaged. Conventional medal conveyance devices have a large number of parts, so they have the disadvantage of requiring time to repair.

(Problems to be solved by the invention) In order to solve the above-mentioned drawbacks, the invention uses an endless wire to raise a bucket with a spring to absorb the wire elongation and an opening/closing lid at the bottom. The lid installed at the bottom of the bucket is automatically opened, the medals are dropped into the supply chute on the supply side, the bucket is stopped for a certain period of time, and the medals in the bucket are completely dropped, eliminating any remaining medals in the bucket. However, the opening/closing lid is returned to its original position during the lowering of the bucket.

(Means for Solving the Problems) The present invention has a system that allows the distance between the lower limit position where medals are dropped into a bucket with a lid that can be opened and closed at the bottom and the upper limit position where the medals are dropped into the chute to be raised. The bucket is raised and lowered by a lifting mechanism, and a bucket opening/closing rod protruding from the opening/closing lid works together with the rising bucket to open the opening/closing lid to the chute side by a guide mechanism, and the medals are dropped into the chute. an upper limit switch that senses the upper limit on the raised bucket;
A solenoid is used to operate the bucket locking rod for a certain period of time, which receives the bucket which has stopped rising due to ON, and the opening/closing lid of the bucket is opened for a certain period of time to eliminate any remaining medals in the bucket. In addition, an endless wire is used for the wire, and in order to absorb the elongation of the wire and maintain the tension of the wire, it is connected with a tension spring and provided in an endless shape.

(Example) Reference numeral A in the figure indicates a frame of the present invention, and reference symbol B indicates a rail provided on frame A.

Further, all operations of the present invention are controlled by a timer.

_M2 is a drive motor, and when the drive motor _M2 rotates in the normal direction, the bucket 6 rises, and when the drive motor M2 rotates in the reverse direction, it moves down.

The drive motor _M2 is connected to a pulley 2 provided below the frame A by an endless wire 3, and a bucket belt ₆ is attached to the endless wire 3. 6 is designed to move up and down, and when the motor _M2 is stopped, a reversal circuit is turned on to switch between reverse rotation and forward rotation in preparation for driving the motor _M2 .

The endless wire 3 is attached to the drive pulley 1a attached to the motor shaft 1 in a double-wound manner to prevent the drive pulley 1a from spinning idle, and one end of the endless wire 3 is connected to the first
As shown in the figure, the other end is connected to the upper part of the back of the bucket 6, and the other end is connected to the middle part of the back of the bucket 6 via a tension spring 4a in order to absorb the elongation of the wire and maintain the tension of the wire, making it endless. There is.

Further, the endless wire 3 is connected to the tension pulley 4 from a position facing the tension spring 4a.
It is always in a state of no deflection because it is pressed by the

Reference numeral 5 denotes a bucket locking portion, which is fixed to the back of the bucket 6. Furthermore, a limit switch operating plate 11 is provided on the back of the bucket 6, and a limit switch operating plate 11 is provided on the back of the bucket 6.
When it comes into contact with the upper limit switch _SW5 provided on the frame A, the drive motor _M2 stops for a preset time.

Simultaneously with the stoppage, the solenoid 13 is energized to tilt the bucket locking rod 12 forward, so that the bucket locking rod 12 supports the bucket locking portion 5 (see FIG. 1).

The bucket bag 6 is provided with a rail guide 15 on the upper part of the back side, and this rail guide 15 holds the rail B.
Accordingly, the bucket 6 is designed to move up and down, and an opening/closing lid 7 is attached to the bottom via a shaft 9 so as to be able to be turned upside down. The opening at the bottom of 6 is closed.

Therefore, the bucket 6 rises, and the bucket opening/closing rod 10 provided at the bottom of the opening/closing lid 7 comes into contact with the opening/closing rod receiving plate 14 attached to the frame A, and the opening/closing lid 7
is raised until it falls forward, the upper limit switch SW ₅ is activated, the drive motor M ₂ is stopped, and the medals in the bucket 6 fall through the supply chute 17 into the supply hopper 18 .

When the bucket 6 is lowered, the bucket opening/closing rod 10 is released from the opening/closing rod receiving plate 14, and the opening/closing lid 7 is automatically returned to its original position by the tensile force of the coil spring 8.

When the upper limit switch SW ₅ comes in contact with the limit switch operating plate 11 of the rising bucket 6, it automatically stops the rotation of the motor M ₂ and at the same time, the solenoid 13 is energized, and the bucket locking rod 12 is activated as shown in FIG. It is designed to tilt forward and support the bucket locking part 5.

Further, when the predetermined (previously set by a timer) stop time of the drive motor M ₂ when medals fall from the raised bucket 6 to the supply hopper 18 has passed, the drive motor M ₂ rotates again, and at the same time the solenoid 13 is demagnetized, the bucket locking rod 12 returns to its original position, and the bucket 6 descends.

The opening/closing rod receiving plate 14 is horizontally fixed to the frame A, and the bucket opening/closing rod 10 of the aforementioned opening/closing lid 7 is latched to the portion that protrudes forward (to the left in the drawing). As a result, the opening/closing lid 7 is tilted, and the medals in the bucket 6 fall into the supply hopper 18 via the supply chute 17.

SW ₆ is a lower limit switch, which is provided on the lower rear part of the frame A. When the bucket 6 is lowered, the limit switch operating plate 1 of the bucket 6 is lowered.
1 contacts the lower limit switch SW ₆ , it is activated and stops the drive motor M ₂ for a preset time. This stop time is the time for supplying medals into the bucket 6 and becomes the supply amount of medals.

When the drive motor _M2 stops, the collection hopper 19
The collection motor _M3 operates to feed medals from the collection hopper 19 into the bucket 6 via the supply chute 20, and the amount of medals supplied from the collection hopper 19 into the bucket 6 is controlled by a timer. Therefore, it can be set arbitrarily, and the bucket 6 is stopped for the set time.

Reference numeral 16 denotes a lower stopper, which supports the lowered bucket 6 at the lower limit position.

Furthermore, when the bucket 6 containing medals reaches the upper limit position, the supply hopper 18 becomes full after medal replenishment, and the switch SW ₃ is turned on, the bucket 6 descends and activates the lower limit switch SW ₆ . The drive motor _M2 stops and the bucket 6 waits on the lower stopper 16, but medals are fed from the collection hopper 19.

When the replenishment hopper 18 is no longer full, the switch SW ₃ is turned off, and the bucket 6 rises again to perform a predetermined operation.

In addition, if the bucket 6 containing medals is raised and the medals in the supply hopper 18 collapse, etc., and the medals hit the switch and the switch SW ₃ is turned on as in the case when the bucket is full, the bucket 6 will not be driven. Due to the reverse rotation of the motor M ₂ , the bucket 6 descends to the lower limit position with the medals accommodated in the middle, and the limit switch actuating plate 11 contacts the lower limit switch SW ₆ to stop the drive motor M ₂ , so that the bucket 6 is moved above the lower stopper 16 . to wait.

In this state, when the upper replenishment hopper 18 is no longer full and the switch SW ₃ is turned off, the bucket 6 rises again and performs a predetermined operation.

(Effects of the invention) As stated above, the invention uses a single endless wire powered by a motor to raise and lower the bucket, so it is a simple mechanism and an automatic system for reliably supplying and replenishing medals, coins, etc. It is a transport device with a small number of parts, low noise, and has excellent functions with fewer failures. Furthermore, since the drive motor is stopped under timer control when supplying medals to the bucket, there is the advantage that the time can be freely varied even if the amount of medals used changes depending on the application. Furthermore, when the medals in the bucket are replenished from the top, the remaining medals in the bucket are eliminated, so there is no longer any inconvenience caused by the remaining medals.
