Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a reversing device for reversing a plate.

[Conventional technology and its problems]

Generally, when grinding both sides of a plate using a surface grinder, after grinding the top surface, the plate is turned upside down and the bottom surface is ground.

By the way, conventionally, when reversing a plate material.

Board material made by several workers! Either by holding the plank and turning it over, or by hoisting the plank using a hoist crane, the worker turned it over while dropping one end of the plank. In any case, the plate material is turned over manually, which causes problems in that the work is difficult and the workers are highly fatigued.

[Means for solving the gap]

In this invention, there is provided a transfer means for loading and transferring a plate material, and by rotating the transfer means from below to upward, the plate material which has been placed *a at the tip Is of the transfer means is placed on the upper surface.
The above problem is solved by a configuration including a rotating arm that rotates the plate in this state until the top surface of the plate faces downward, thereby inverting the plate at the rear end of the transfer means. ing.

Next, the plate material reversing device ai2 will be explained. The plate material reversing device w12 is composed of a belt conveyor (transfer means) 7 and a single reversing mechanism 8.

The conveyor 7 is constructed as follows.

That is, a position 1zK at a predetermined distance from the 7th frame 5b of the rice-boot conveyor 4 is a machine frame 9 parallel to the frame 5b.
is installed. A drive shaft 11 is rotatably attached to the machine frame 9 to which a plurality of pulleys lO, 10, . . . are fixed at predetermined intervals in the longitudinal direction. This drive shaft 11 is adapted to be rotated by a drive device 12. On the other hand, below the rollers 6 of the T-Ra conveyor 4 and near the frame 5a, there is a frame 5a. A machine frame (not shown) is arranged in parallel, and a driven shaft 14 to which a plurality of boots IJ-13, 13, etc. are fixed at a predetermined distance of 1% 11g4 in the longitudinal direction is movable up and down on this machine frame. , and is rotatably mounted.

Then, one roller 6 #6 of the roller conveyor 4 is located opposite to the pulleys 13, 13, and so on.
The roller conveyor 4 is located at an intermediate pressure, and its traveling direction is perpendicular to the conveying direction of the roller conveyor 4.

Further, the driven shaft 14 can be moved up and down Vcs by cylinders 16, 16 installed below both ends thereof, and at its rising end, each belt 15,
The upper surfaces of the tips of the rollers 15 are positioned above the upper surfaces of the rollers 6, 6, and so on.

Based on the above configuration, the belt conveyor 7 moves the plate placed on the rear end side in the direction of the hit arrow with the tip end raised, and transfers it to the upper side of the roller conveyor 4. First, the tip of the belt conveyor 7 is lowered and the plate material is placed on the rollers 6, 6, etc. It is now possible to place

Next, the reversing machine tR8 is configured as follows. That is, in the conveying direction of the belt conveyor 7, I11'1
At the outer positions on both sides of the belt conveyor 7, mounts 17 and 18 and mounts 18 and 18 are respectively installed so as to face each other. These opposing frames 17.1
Shaft bodies 19 and 19 are rotatably attached to the shafts 8, 17 and 18, respectively. These shafts 19, 19 are mounted perpendicularly to the conveying direction of the belt conveyor 7 in the shape WJ5, and are located at predetermined intervals in the longitudinal direction. 20-20-°
.

The ends of the plurality of auxiliary arms 21, 21, . . . are fixed. Furthermore, one end portions of arms 22, 22 are fixed to one end portions of the shaft bodies 19, 19, respectively. The other end portions of these arms 22, 22 are linked and connected to the tip portions of pistons 24, 24 of cylinders 23, 23, which are arranged approximately horizontally, respectively.

Based on the above configuration, the reversing mechanism 8 includes the pistons 24 and 24.
