Abstract

PURPOSE:To provide a pallet for a shaft drive type conveyer of simple structure, in which even if water drops are stuck on a drive shaft, transporting force is not lowered in a device to transport members and products in a production equipment in particular. CONSTITUTION:Sand blast process is applied on the surface of a drive shaft 24 to increase the coefficient of friction between the drive shaft 24 and a drive roller 23. By this sand blast application, even if water drops are stuck to the drive shaft 24, the coefficient of friction between the drive roller 23 and the drive shaft 24 are not remarkably decreased, which can prevent the remarkable lowering of pallet transporting force. In addition, the simplicity of the structure makes it possible to place a pallet on an arbitrary position on a conveyer or to remove a pallet from an arbitrary position on the conveyer.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a pallet for a shaft-driven conveyor, and particularly to a pallet for use in a manufacturing facility.
Related to pallets for shaft drive conveyors that transport parts, products, etc.

0002

2. Description of the Related Art In recent years, with the rapid automation of factories, pallets for shaft-driven conveyors that convey parts, products, etc. at high speed have become indispensable.

[0003] The above-mentioned conventional shaft drive type conveyor pallet will be explained below with reference to the drawings.

In FIG. 3, 1 is a flat plate of a pallet, 2 is a vertical roller attached to the lower surface of the flat plate 1 by a mounting bracket 7, and 3 is a drive roller attached to the lower surface of the flat plate 1 by a bracket 8 and a lever 9. The drive roller 3 is swingable in the θ direction shown in FIG. 10 is a rail on which the vertical roller 2 rolls, and the frame 1
1, and this frame 11 is fixed to leg portions 12 to constitute a conveyor. 4 is a drive shaft fixed to the leg 12 via a plurality of bearings 13 and rotated by a motor 6 via a belt 5 at a location other than the bearings 13; This is a cover that prevents substances from falling or scattering.

The shaft-driven conveyor pallet constructed as described above is configured such that when the drive roller 3 is in the posture X shown in FIG. 3, the conveying force is transmitted from the drive shaft 4.

[0006]

[Problems to be Solved by the Invention] However, the above-mentioned pallet has a cover 14 that prevents water droplets from adhering to the drive shaft 4.
15, it is not possible to completely prevent this, and when water droplets adhere, the friction coefficient between the drive roller 3 and the drive shaft 4 decreases, resulting in a significant decrease in the conveying force. Furthermore, there was a problem in that it was very difficult to remove the pallets from the conveyor for maintenance. The present invention solves these problems, and the conveying force does not decrease even if water droplets adhere to the drive shaft.
The purpose of the present invention is to provide a pallet for a shaft drive type conveyor with a simple structure.

[0007]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the pallet for a shaft-driven conveyor of the present invention has a drive shaft subjected to side blasting on the surface.

[0008]

[Function] Due to the above-described structure, the pallet for a shaft-driven conveyor of the present invention can prevent water droplets from adhering to the drive shaft by side blasting the surface of the drive shaft. The friction coefficient between the pallet and the pallet does not decrease significantly, and the propulsion force of the pallet is prevented from decreasing significantly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A pallet for a shaft-driven conveyor according to an embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a plurality of rotatable vertical rollers 22 are attached to the left and right sides of the lower surface of the flat plate 21 via mounting brackets 27, and the rotating shafts 22a are perpendicular to the direction of travel and parallel to the ground. , a pallet having a drive roller 23 which is attached via a mounting bracket 28 and whose rotating shaft 23a is kept horizontal with the ground and whose angle with the traveling direction is variable between 90° and 45°; and a vertical roller. A pair of left and right rails 30 are arranged on the legs 32 via a frame 31 so that the rails 22 roll on the upper surface thereof, and a plurality of bearings 33 are arranged so that the rotation axis is parallel to the direction of travel and horizontal to the ground.
The conveyor has a drive shaft 24 supported by a motor 26 via a belt 25, and the drive roller 23 and drive shaft 24 are in contact with each other, and the angle between the rotation axes of the two is between 0° and 45°. A pallet for a shaft-driven conveyor, in which the propulsion force of the pallet on the conveyor is variable as the angle changes, and the pallet has drive rollers 2 on the surface of the drive shaft 24.
It has a sandblasted structure to increase the coefficient of friction with 3.

Next, the operation of the shaft-driven conveyor pallet of this embodiment will be explained. The conveyance force is transmitted to the flat plate 21 of the pallet from the drive shaft 24 via the drive roller 23. At this time, even if water droplets adhere to the drive shaft 24, the friction coefficient increases on the surface of the drive shaft 24. Because side blast processing is given,
The friction coefficient between the drive roller 23 and the drive shaft 24 does not decrease significantly, and it is possible to prevent the pallet conveyance force from decreasing significantly. Further, since there is no cover covering the drive shaft 24 from above or from the side, the pallet can be easily placed on or removed from any position on the conveyor.
