2. Description of the Related Art When replenishing medals to a plurality of slot machines and a medal lender installed between them in a linearly arranged transportation place, for example, at a game hall, a partition plate is divided into a plurality of parts except an upper part inside. There is one in which a bucket provided with a bottom lid that can be opened and closed is run and the bottom lid is opened at the replenishment location to replenish.

[0003]

SUMMARY OF THE INVENTION In the bucket transport device described above, the bucket is connected to the timing belt stretched between the driving pulley and the driven pulley, and the bottom lid is connected between the other driving pulley and the driven pulley. It was connected to a stretched timing belt so that each drive source could be driven by another drive source in synchronization with each other. At the replenishment position, the bottom lid is stopped and the bucket is advanced to open the bottom lid to replenish the transported object. As described above, if the driving means for the bucket and the bottom lid are driven by different driving sources, acceleration and deceleration will occur at the start of running and when the origin is stopped, so even if the encoder detects rotation, In some cases, the synchronized control could not be performed, the bucket and the bottom lid were misaligned with each other, and the transported object dropped.
Therefore, an object of the present invention is to provide a bucket transporting device that can synchronize the driving means for the bucket and the bottom lid with each other at the time of starting and at the time of stopping so as not to be displaced from each other.

[0004]

In order to achieve the above object, the present invention provides the following bucket carrying device. In other words, the object to be conveyed such as medals is stored in a bucket having a bottom lid and is conveyed to a plurality of linearly arranged places as needed, and the drive means of the bottom lid is directly connected to the drive means of the bucket. The bucket and the bottom lid are configured to be synchronously driven by a single drive source, and the drive means for connecting the bucket and the bottom lid can be released to open the bottom lid at the replenishment position. It is a bucket transport device.

[0005]

Since the driving means for the bottom lid is directly connected to the driving means for the bucket and the bucket and the bottom lid are driven in synchronization by one driving source, the bucket travels with the bottom lid closed.
At the replenishment position, the drive means of the bottom lid is released from the direct connection state with the drive means of the bucket and stopped by the braking action, and only the bucket is connected to the drive source. Can be dropped. After replenishment, the bucket retracts to the bottom lid stop position and closes the bottom lid. In this closed state, the drive means for the bottom lid is directly connected again to the drive means for the bucket, so that the bucket and the bottom lid together return to the origin.

The driving portion of the timing belt 5 is composed of a pulley 10 driven by a motor 8 via a speed reducer 9 as shown in FIG. 13, and the timing belt 5 is stretched between a pulley 10 and a driven pulley 11. The timing belt 5 is also provided with gap adjusting pulleys 12 and 13 on the driving portion a and the driven portion b in order to keep the distance from the timing belt 4. A sensor mounting plate (14) is provided below the traveling origin c on the driving side of 12, 13.
Is attached to the deceleration position sensor (15) of both the bucket (1) and the bottom lid (3), the stop position sensor (16) of the bucket (1) and the stop position sensor (17) of the bottom lid (3). Is attached. Each of the above sensors has a bucket (1) and a bottom lid (3) at the traveling origin (c).
It detects the deceleration and stop position of. The side surface of the bucket has a detection plate (18) corresponding to the sensors (15) and (16), and a stop position sensor (17) of the bottom lid (3).
Is adapted to be activated by the bottom lid (3) itself.

Now, a large number of medals are always put in the bucket (1) and stand by. Next, the bucket (1) is driven by a motor (4a) and a speed reducer (5a) in response to a request signal for a medal to be supplied
The vehicle is driven by a timing belt (4) driven by a pulley (6) via. The bottom lid (3) also moves at the same speed as the bucket (1) by the timing belt (5) driven by the pulley (10) via the motor (8) and the speed reducer (9).
Then, it stops at the replenishment destination that issued the request signal from the preset movement distance of the replenishment destination. After stopping at the supply destination, the bucket (1) advances to open the bottom lid (3) and drop the transported object on the medal receiving hopper (2). After the replenishment, the bucket (1) retracts and closes the bottom cover (3), and then the bottom cover (3) and the bucket (1) together return to the traveling origin c, and the deceleration position sensor (15) decelerates. Stop position sensor (1
Stop at 6) and (17).

Using the above-described bucket transporting apparatus, the bucket (1) is transported in a state as shown in FIG. 14 in which a partition plate (23) having the inside divided equally except the upper portion is set as shown in FIG. To be done. That is, the temporary holding tank (2
After confirming that the bottom lid (21) of 2) is closed, the medals are discharged from the tank (19) to the temporary storage tank (22) through the discharge chute (20). When controlling the number of sheets with high accuracy, a counting sensor is provided at the discharge part of the tank (19). When the approximate number of sheets is sufficient, the operating time of the discharge part of the tank (19) is controlled. After confirming that the bucket (1) is empty and is located under the temporary holding tank (22) and the bottom lid (3) is closed, the bottom lid (21) of the temporary holding tank (22) is opened by an opening / closing means. . The speed at which this bottom lid (21) is opened depends on the partition plate (2) of the bucket (1).
Set so that medals fit evenly in each room separated by 3). Then, the bucket (1) is called by the above-mentioned transfer means and is transferred to the upper part of the hopper (2) to which the medal is supplied, and stopped. After the stop, the bottom cover (3) is opened in the same manner as described above, and after replenishment, the bottom cover (3) closes the bucket (1) with the progress of the bucket (1) and closes the bucket (1) and the bottom cover (3). Tank together (2
Return to the bottom of 2).

In the above-described transporting apparatus, the driving means for the bucket and the driving means for the bottom lid are driven by different driving sources, so acceleration and deceleration are involved at the time of starting and stopping, so even if they are rotated by an encoder. It is difficult to synchronize even if it is detected. The main idea is to improve this. That is, the driving means for the bottom lid is directly connected to the driving means for the bucket so that the bucket and the bottom lid can be driven synchronously by one driving source. As a result, synchronization can be achieved even during acceleration or deceleration at the time of starting or stopping, and the bottom lid and the bucket do not move while deviating from each other.
However, in order to open the bottom cover at the replenishment position, the drive means for the bucket and the bottom cover can be released from the direct connection state, and the drive means for the bottom cover is provided with a braking action. One of them is a two-clutch system.
1 to 3, a shaft (27) is driven by a motor (25) via a coupling (26) to drive a pulley (28) of the bucket (1). Motor (2
5) and the bucket drive shaft (27) may be driven by a timing belt as shown by the other dotted line for direct drive. The pulley (29) and the pulley (24) are interlocked by the belt (30), but the bottom lid drive shaft (31) is interlocked with the pulley (29) via the clutch (32) to drive the bottom lid of the pulley (33). The shaft (31) is braked by a clutch (34).

Now, when the clutch (32) is turned on and the clutch (34) is turned off and the motor (25) is started to drive the pulley (24) and the pulley (29) through the belt (30), the pulley (33) is driven. And the pulley (28) are interlocked with each other, and the bucket (1) and the bottom lid (3) travel together and stop at a fixed position. The clutch (3
2) is turned off, the bottom lid drive shaft (31) is freed, and the bottom lid drive shaft (31) is turned on by turning on the clutch (34).
Stop. Then, the motor (25) is activated, and the pulley (28) is driven by the activation to move the bucket (1) forward with the bottom lid (3) stopped, so that the bottom lid (3) is opened and medals are supplied. . After replenishment, the bucket (1) returns to the stop position of the bottom lid (3). When the clutch (32) is turned on and the clutch (34) is turned off, the motor (2
5) is activated, the bucket (1) and the bottom lid (3) travel together and return to the origin. With the above configuration, the driving means of the bottom lid (3) can be directly connected to the bucket driving means and can be synchronized with each other, and the bucket (1) and the bottom lid ( There is no deviation from 3). In the replenishment position, however, the bottom lid driving means can release the direct connection state with the driving means of the bucket (1) so that the braking action is exerted by the driving means of the bottom lid (3) in association with the releasing operation. Only the bucket (1) can be moved forward and backward by stopping the bottom lid (3), and the bottom lid (3) can be opened at the replenishment position to drop the medal to the replenishment position and the bottom lid (3) after replenishment. ) Can be closed.

FIGS. 4 to 9 show a mechanical detent system using one clutch so that the drive means of the bottom lid (3) can be directly connected to the drive means of the bucket (1) to be released. . As shown in FIG. 6, the spring (42) is attached to the tubular body (41) fixed to the bracket (40) of the bucket (1).
The bucket (1) and the bottom lid (3) can be integrated by using the plunger (43) which is biased by and is fitted into the hole (3a) of the bottom lid (3).
Further, as shown in FIGS. 7, 8 and 9, a plunger (44) which can be inserted into and removed from the bracket (45) of the bucket (1) by a push pull or a rotary sole (46) is used, and this is used for the hole (3a) of the bottom lid (3). The bucket (1) can also be integrated with the bottom lid (3) by fitting into the bottom cover (3). The bottom lid (3) is driven by the driving means by the pulley (37) of the bottom lid driving shaft (38) in FIG. 4, but is directly connected to the driving means of the bucket (1) by the above structure. become. The bottom lid drive shaft (38) is configured to be braked by the clutch (39). Now turn off the clutch (39)
In this state, the motor (35) is activated, and the pulley (36) activates the drive means of the bucket (1). In this case, since the plunger (43) is urged downward by the spring (42) and locked in the hole (3a) of the bottom lid (3), the driving means of the bucket (1) and the bottom lid driving means are interlocked. work. Therefore, the bottom lid (3) and the bucket (1) travel together.

Then, at a fixed position, the clutch (3
9) When turned on, the shaft (38) is braked to stop the bottom lid (3) and only the bucket (1) is moved forward and backward to open or shield the bottom lid (3). At this time, since the bucket (1) advances while the bottom lid (3) is stopped, the plunger (43) can be retracted against the force of the spring (42) to unlock. Therefore, the bucket (1) can move forward freely. Then, when the bucket (1) returns to the stop position of the bottom lid (3) after replenishing medals, the plunger (43) fits into the hole (3a) and is locked. Therefore, the bucket (1) and the bottom lid (3) can be returned to the origin as a unit. In FIGS. 6, 7 and 8, the push-pull or rotary solide has a similar locking mechanism so that the bottom lid (3) and the bucket (1) are integrated or released. In the mechanical detent type embodiment described above, the driving means of the bottom lid (3) can be directly connected to the driving means of the bucket (1), and the bucket ( There is no disengagement between 1) and the bottom cover (3). At the medal replenishment position, however, a braking action acts on the drive means of the bottom cover (3) to stop the bottom cover (3), and by operating only the drive means of the bucket (1) in this stopped state, the bottom cover ( It is possible to cancel the state in which the drive means of 3) is directly connected to the drive means of the bucket (1), and it is possible to freely move only the bucket (1) forward and backward. All of the above are one embodiment, and any means can be adopted as the drive means for the bucket (1) and the bottom lid (3).

[0014]

According to the present invention, the drive means for the bottom lid is directly connected to the drive means for the bucket, and the bucket and the bottom lid can be driven synchronously by one drive source. Even if the accelerating action and the decelerating action are applied, they do not deviate from each other, so that the trouble that the transported object falls from the bucket does not occur. Further, since the direct connection state of the drive means between the bucket and the bottom lid can be released at the replenishment position, only the bucket can move forward and backward with the bottom lid stopped, the bottom lid is opened and the transported object is dropped to the replenishment position. The bottom lid can be closed. Then, since the driving means for the bottom lid and the driving means for the bucket are directly connected again with the bottom lid closed, the bucket and the bottom lid can be returned together to the origin. According to the present invention, the driving means for the bucket and the bottom lid can be synchronized with a simple configuration, and the bottom lid can be opened and closed in synchronization with the replenishment position.
