Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing table for a cutting machine, which is used when cutting a tool with a cutting machine such as a plasma cutting machine.

[0002]

2. Description of the Related Art Conventionally, for example, as a plasma cutting machine, a three-dimensional main body frame is provided with a portal frame movable in the X-axis direction, and a machining torch provided in the portal frame is movable in the Y-axis direction. A head is provided. Further, a processing table for loading works is fixedly provided on the body frame.

With the above construction, after the work is loaded on the working table, the gate frame is moved in the X-axis direction and the working head is moved in the Y-axis direction. Is performed.

[0004]

By the way, in the above-mentioned conventional plasma cutting machine, since the processing table is fixedly provided on the body frame, when the work is heavy, the work is handled by the operator. However, it is difficult to load the workpieces onto the processing table or carry out the workpieces by using a carrier such as a crane or a forklift. Therefore, it is necessary to carry out the work while observing the interference between the cutting torch and the carrying device, which makes it difficult to carry in and carry out the work.

Further, when a large-sized work is cut on the working table and it is difficult to take out the cut object from the periphery of the working table, an operator must climb on the working table to work. There was a danger that it did not happen.

In order to solve the above problems, an object of the present invention is to provide a cutting machine which can easily carry in and carry out a work regardless of whether the work is heavy or large in size. The purpose is to provide a processing table.

[0007]

In order to achieve the above object, the present invention is a processing table for a cutting machine, on which a work to be cut by a cutting machine is placed, which is provided in an upright body frame. In order to load and unload the work from one side and to the same direction, a processing table composed of a conveyor that is movable in the front-rear direction is provided.

[0008]

By adopting the processing table for a cutting machine of the present invention, a processing table composed of a conveyor that is movable in the front-rear direction is provided in the upright body frame. After the work is loaded on the processing table, desired cutting processing is performed.
When the cutting process is completed, the processing table is moved in the same direction and the work is carried out in the same direction.

[0009]

Embodiments of the present invention will be described in detail below with reference to the drawings.

Referring to FIGS. 1 and 2, for example, a plasma cutting machine 1 as a cutting machine is provided with an upright body frame 3, and the body frame 3 is provided with a plurality of upright columns 5. It is composed of a plurality of reinforcing frames 7 extending in the Y-axis direction supporting the columns 5, and a plurality of upper frames 9 provided on the columns 5 extending in the X-axis direction.

An X-axis rail 11 extending in the X-axis direction is laid on the upper frame 9, and a gate-shaped frame 15 is provided in the X-axis direction via a plurality of guide members 13 on the X-axis guide rail 11. It is movably installed.

With the above structure, when a drive motor (not shown) is driven, the gate-shaped frame 15 is guided by the X-axis guide rail 11 via the guide member 13 by the ball screw, nut member, etc., and moved in the X-axis direction. Will be done.

A Y-axis guide rail 17 extending in the Y-axis direction is laid on the gate-shaped frame 15.
A support member 21 is provided on the shaft guide rail 17 via a guide member 19 so as to be movable in the Y-axis direction. A cutting torch 2 is provided on the front side (right side in FIG. 1) of the support member 21.
3 is provided via a bracket 25.

With the above structure, when a drive motor (not shown) is driven, for example, the support member 21 is guided by the Y-axis guide rail 17 via the guide member 19 via the ball screw, nut member, etc., in the Y-axis direction. Will be moved.

Therefore, by moving the gate-shaped frame 15 in the X-axis direction and moving the support member 21 in the Y-axis direction, the cutting torch 23 is moved in the X-axis and Y-axis directions.

A bracket 27 is integrally attached to the inside of each of the upper frames 9.
Between 7 is a rotatable rotary shaft 29F extending in the Y-axis direction,
29B is supported.

Drive sprockets 31R and 31L and driven sprockets 33 are provided on both sides of the rotary shafts 29F and 29B.
R and 33L are fitted, and chains 35L and 35R are respectively wound around the drive sprockets 31R and 31L and the driven sprockets 33R and 33L. A driven pulley 37 is fitted to one end of the rotary shaft 29F.

On the other hand, a bracket 39 is attached to the column 5 on the left side in FIG. 1, and a drive motor 41 is provided on the bracket 39. This drive motor 4
A drive pulley 43 is fitted on the output shaft of No. 1, and a belt 45 is wound around the drive pulley 43 and the driven pulley 37.

Further, a conveyor table 49 as a processing table is formed by arranging needle-like objects 47 on the chains 35L, 35R for placing, loading and unloading the work W at appropriate intervals.

With the above structure, when the drive motor 41 is driven, the drive pulley 43, the belt 45, and the driven pulley 37.
The rotary shaft 29F is rotated via the. This rotating shaft 29F
The rotation of the drive sprockets 31R and 31L causes the chains 35R and 35L to rotate and rotate counterclockwise or clockwise.

On the rear side of the frame body 3 (on the right side of the right column 5 in FIG. 1), an auxiliary table 51 for temporarily placing the work W is provided, and a product G discharged from the conveyor table 49 after cutting. Is provided with a product receiving box 53.

With the above structure, a heavy work W is loaded on the auxiliary table 51 by, for example, a crane or a forklift. When the auxiliary table 51 is operated and the work W is transferred onto the plurality of needle-shaped objects 47 of the conveyor table 49, the drive motor 41 is rotated in the forward direction, and the conveyor table 49 moves leftward in FIG. Then, the work W is positioned on the conveyor table 49. Then, the cutting torch 23 is moved in the X-axis and Y-axis directions, whereby the workpiece W is subjected to desired cutting.

When the drive motor 41 is rotated in the reverse direction after the cutting process is completed, the conveyor table 49 moves rightward in FIG. 1 and the work W is returned to the auxiliary table 51, at which time the product G is removed from the work W. It falls and is stored in the product receiving box 53.

Thus, the conveyor table 49 as a processing table is moved in the front-rear direction so that the work W is carried in from one side and carried out in the same direction. Therefore, the work W is a heavy object. Also,
Alternatively, even if it is a large size, it can be easily loaded and unloaded.

The present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes. In the present embodiment, the plasma cutting machine is described as an example of the cutting machine, but a laser processing machine or the like may be used.

[0026]

As will be understood from the above description of the embodiments, according to the present invention, since the construction is as set forth in the claims, even if the work W is a heavy object, Alternatively, even if it is a large size, it can be easily loaded and unloaded.
