DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport belt and a transport belt .
With a cloth belt for polishing balls that is provided facing the feed belt
Pachinko ball is pinched, and the pinched pachinko ball is
From the lower part of the cloth belt by the rotation of the lifting belt
The present invention relates to a ball polishing / lifting device which is lifted upward and polished by the cloth belt .

[0002]

Conventionally, so as to face a fabric belt for <br/> ball polish pachinko ball holding surface of the conveyor belt to sandwich the pachinko balls
In a ball polishing / lifting device that transports while polishing, the cloth belt with dirt on pachinko balls is manually pulled and rolled in or folded at the end of the hall business or when dirt is very dirty. Thus, it is stored in a cloth belt mounting box formed on the back of the ball polishing and transporting device.

[0003]

However, since the above-mentioned work is performed in a narrow space of the pachinko island stand, the workability is poor. Since the cloth belt winding operation competes with other operations, improvement thereof has been desired. The present invention
In view of the above circumstances, an object of the present invention is to provide a ball polishing / lifting device which can smoothly and easily take up a soiled cloth belt.

[0004]

In order to achieve the above object, according to the first aspect of the present invention, a pachinko ball is held between a conveyor belt and a ball polishing cloth belt provided facing the conveyor belt. Then, in a ball polishing / lifting device that lifts the pinched pachinko balls from a lower portion to an upper portion of the cloth belt by rotation of the lifting belt and grinds with the cloth belt, the ball polishing / lifting device includes: A cover plate that can be installed with the cloth belt facing the pachinko ball pinching surface of the conveyor belt, and the cover plate has a winding mechanism that winds up a used cloth belt by a driving force of a motor; To prevent unnecessary feeding of the cloth belt
Disposed a sending unit for pressing the fabric belt, the moving direction of the pachinko balls clamping face of the fabric belt by winding operation of the winding mechanism are the same as the moving direction of the pachinko balls clamping face of the conveyor belt Direction. With this configuration, when lifting the pachinko balls by the rotation of the conveyor belt, the frictional force at the time of polishing the pachinko balls applied to the cloth belt is in the lifting direction, that is, the moving direction of the conveyor belt in the pachinko ball holding surface. Therefore, if the feeding unit is fixed to the cloth belt, the frictional force causes the cloth belt itself to extend in the same direction as the moving direction of the conveyor belt, causing slack at the top of the cloth belt. However, since the winding mechanism operates in the direction of winding up the slack of the cloth belt, the slack due to the elongation of the cloth belt can be smoothly absorbed, and the ball polishing and lifting device due to the slack is adversely affected. (Loosening of slack by pachinko balls, lowering of lifting capacity) and the like can be prevented beforehand, so that the work of winding the cloth belt can be performed smoothly and easily. In addition, friction when polishing pachinko balls on the cloth belt
Since the force is the same as the moving direction of the conveyor belt, the winding mechanism
Motors are not overloaded because some motors are not overloaded.
Data capacity can be reduced and the back of the cover plate
In addition, a motor of the winding mechanism can be provided. Further
In addition, the take-up mechanism section and the sending section are arranged on the back of the cover plate.
Before installing these devices on the cover plate and adjusting
Shipment of the ball polishing equipment after completing the work
This makes it possible to simplify on-site work.
Further, in the invention according to claim 2, the winding mechanism section includes:
A tension driving unit configured to include a plurality of rollers disposed at a position where the used cloth belt is pressed so as to be in a meandering shape and pulling the used cloth belt by rotating at least one roller with a motor; A winding unit provided separately from the pulling drive unit and winding the cloth belt pulled in the pulling drive unit into a roll by the driving force of a motor. With this configuration, the pulling operation and the winding operation of the cloth belt can be performed by separate motors, so that the winding operation can be performed smoothly. It can be pressed and pulled in a meandering manner, and the pulling operation can be performed reliably.

Is turned manually to pull out the required length of the fabric belt 80 downward. Thereafter, the cloth belt 80 is inserted from the lower part to the upper part of the front surface of the cover plate 8 in the opened state, and the cloth belt 80 is inserted between the driving roller 20 and the pressure roller 21 of the tension driving unit 11. At this time, the interval between the pressing roller 21 and the driving roller 20 is loosened, and the fabric is rolled down onto the winding shaft 33 for forming the fabric belt roll 80b after use by hanging downward and passing the back side of the rotating shaft 35. The front end of the belt 80 is fixed, and then the drive roller 20 and the pressure roller 21 are pressed. The extra belt 80 pulled out is wound around the winding shaft 33, and in this state, the winding cam 37 of the holding lever frame 34 is brought into contact with the outer periphery of the cloth belt roll 80b after use. As described above, the cloth belt 80
After the installation of the cover, the cover plate 8 is closed and the fastening lever 9 is closed.
To make the cloth belt 80 and the transport belt 5 face each other.

Next, the operation during driving of the ball polishing and lifting device 1 will be described. When the ball polishing and conveying device 1 is being driven, the pulling motor 17 and the winding motor 4 of the winding mechanism 10 are driven.
1 is constantly driven to rotate. Therefore, the cloth belt 80 is always wound up, but is actually wound up by the following operation. That is, while the pachinko balls are being conveyed by the conveyor belt 5, the cloth belt 80 is always forced up by the frictional force. For this reason, in the portion of the tension drive section 11,
Since the cloth belt 80 becomes slack, the sliding support 13
Is the lower position. When the slide support base 13 is at the lowered position, the connecting rod 70 is also lowered, and the engaging claw 69 of the stopper lever 67 is engaged with the ratchet gear 66. For this reason, since the rotation of the large-diameter pressure contact roller 63 is stopped, the large-diameter pressure contact roller 63 and the small-diameter pressure contact rollers 64 and 6 are stopped.
5, the supply of the cloth belt 80 is also stopped.

In this state, the cloth belt 80 is not pushed up by the frictional force of the conveyor belt 5, but the tension motor 17 is driven, so that the cloth belt 80 is pulled in the tension drive unit 11. . Then, when the retraction is continued, the sliding support base 13 gradually starts to rise,
Eventually, it rises to a position where the engagement between the engagement claw 69 of the stopper lever 67 and the ratchet gear 66 is released. When the engagement between the engaging claw 69 and the ratchet gear 66 is released, the large-diameter pressure contact roller 63 and the small-diameter pressure contact rollers 64, 6
5, the feeding of the cloth belt 80 is restarted, and the cloth belt 80 is pushed up by the frictional force of the transport belt 5 so that the cloth belt 8
0 is loosened, the slide support 13 is lowered, and the engagement claws 69 of the stopper lever 67 are engaged with the ratchet gear 66. Then, the cloth belt 80 is wound by the winding mechanism 10 while repeating the above-described operation.

As described above, in the present embodiment, the transport

As a result, the moving speed of the cloth belt 80 is determined by the rotation speed of the pulling motor 17, The cloth belt 80 can be moved with a substantially constant degree of contamination because it can be always constant, and the cloth belt 80 is automatically wound up, so that the cloth belt 80 is wound in a narrow island stand. It is not necessary to perform the work, and the cloth belt
The take-up movement of 0 can be easily performed. Further, since the used fabric belt 80 is wound up in a roll shape, the mounting place can be made small, and it can be used for a long time by one long fabric belt roll, and the frequency of replacing the fabric belt is reduced. be able to. In addition, the work of replacing the rolled cloth belt can be easily performed. In the above embodiment, the tension motor 17 and the winding motor 41
The motor capacity does not need to be so large, and the tension drive unit 11 and the winding unit 12 can be designed to be compact.

In the above-described embodiment, an example has been described in which the tension motor 17 and the winding motor 41 are constantly driven to rotate. However, the driving may be intermittently controlled at predetermined time intervals.

[0024]

As apparent from the above description, according to the first aspect of the invention, when the pachinko balls are lifted by the rotation of the conveyor belt, the frictional force applied to the pachinko balls on the cloth belt during polishing is: The lifting direction, that is, the same direction as the moving direction of the conveyor belt on the pachinko ball pinching surface, the cloth belt itself is moved by the frictional force by the frictional force if the sending unit is in a state where the cloth belt is fixed. Direction, the slack occurs at the top of the cloth belt, but the winding mechanism operates in the direction to wind up the slack of the cloth belt. Can be absorbed into the polished ball-feeding device due to looseness (including slackness caused by pachinko balls,
(Reduction of the lifting capacity) can be prevented beforehand, so that the work of winding the cloth belt can be performed smoothly and easily.
Also, the frictional force when polishing pachinko balls on the cloth belt is carried.
