Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cutting apparatus, and more particularly to a cutting apparatus that can perform work efficiently without placing a burden on an operator when cutting a wide variety of workpieces little by little.
[0002]
[Prior art]
When cutting a long workpiece, for example, a long steel material into a number of short steel pieces, place the steel material on a conveyor and feed it toward the cutting machine, clamp the steel material with a vice and cut it to the desired size with a cutting machine After that, it is general to repeat the operation of releasing the clamp and feeding the steel material again to the cutting machine.
[0003]
By the way, in actual cutting work, work pieces having different outer diameters, materials, or cross-sectional shapes may be required little by little depending on the convenience of the product using the work pieces. When cutting a small number of workpiece pieces, it is necessary to stop the cutting operation and replace the long workpiece on the conveyor with another long workpiece having a different outer diameter.
[0004]
[Problems to be solved by the invention]
However, in the conventional cutting device, when an operator tries to change a long workpiece manually, it becomes a heavy burden on the operator, and when an operator tries to change a long workpiece using a crane or a hoist, However, there was a problem that work efficiency was poor in any case.
[0005]
In view of such problems, the present invention has an object to provide a cutting apparatus capable of efficiently performing work without placing a burden on an operator when cutting a wide variety of work pieces little by little. .
[0006]
[Means for Solving the Problems]
Therefore, the cutting device according to the present invention is configured by being fixed on the floor surface and configured by arranging a plurality of conveyors in parallel and extending in the longitudinal direction. A transport line that is fed toward the transport line, a movable table that is movably provided in a direction perpendicular to the transport direction on the transport direction end side of the transport line, and the transport conveyor mounted on the movable table. A cutting machine that cuts the long work fed by the machine, and a clamp mechanism that is provided between the cutting machine and the conveyor and grips the fed long work. .
[0007]
When performing a cutting operation by providing a conveyor for each of a plurality of types of long workpieces, a method of fixing the cutting machine on the floor and moving the plurality of conveyors in the width direction with respect to the cutting machine is conceivable. However, in the case of such a system, in addition to the overall width of the plurality of transfer conveyors, a space for moving the plurality of transfer conveyors in the width direction is required. A large drive mechanism is required to move the entire transport conveyor in the width direction.
[0008]
One of the features of the present invention is that a plurality of transport conveyors are provided in parallel to each other, and the cutting machine is moved in the width direction on the end side in the transport direction of the plurality of transport conveyors. Accordingly, since the cutting machine only needs to be moved with respect to the plurality of conveyors, it is sufficient if there is a space for fixing the plurality of conveyors, and the cutting machine is smaller than the plurality of conveyors. Even when a drive mechanism for moving the actuator is provided, a small drive mechanism is sufficient.
[0009]
In addition, as described above, in the method of moving the transport conveyor in the width direction, the transport conveyor is heavy, and combined with the weight of the long work that is loaded, the whole becomes very heavy, and the transport conveyor starts to move in the width direction. Not only does it take time to stop, but it can be difficult to stop at the exact position due to the inertia of the run.
[0010]
On the other hand, another feature of the present invention is that the cutting machine is moved in the width direction. The cutting machine itself is lighter than the conveyor and workpiece, and the movement can be started and stopped quickly and accurately.
[0011]
In addition, when a work is fed by a conveyor and cut by a cutting machine, a clamp mechanism that grips the work is necessary so that the work does not shift during the cutting operation. If the position is displaced in the width direction, the clamp mechanism hits the workpiece and the workpiece is damaged, which may cause a product defect.
[0012]
On the other hand, in the present invention, the cutting machine can be stopped accurately, and the cutting machine is smaller and lighter than the conveyor, and after the movement of the cutting machine is stopped, the operator can Since the function of finely adjusting the stop position by pushing and pulling can be easily given, the concern about the product defect due to the scratch on the workpiece can be surely solved.
[0013]
The movable table equipped with the cutting machine can be moved freely, and it may be moved by pushing and pulling by hand, but is it possible to move it in the direction perpendicular to the conveyance direction by installing a drive mechanism? Good. As this drive mechanism, a known method such as a motor method, a rack and pinion method, a cylinder method, or the like can be adopted.
[0014]
As long as a cutting machine can cut | disconnect a workpiece | work, any methods, such as a saw blade type, a shearing type, a plasma type, may be sufficient.
[0015]
The clamp mechanism may be provided on the terminal side of each of the plurality of conveyors, but in that case, a large number of clamp mechanisms are required. Therefore, the clamp mechanism is preferably provided between the cutting machine on the movable table and the conveyor. This clamping mechanism can adopt a known method such as a screw feed type vise, a cylinder type vise or the like.
[0016]
The workpiece pieces after cutting may be received by the movable table, but if a large number of workpiece pieces are cut within a short time, the workpiece pieces may not be received by the movable table. Therefore, it is preferable to further include a receiving line for receiving a work piece cut by the cutting machine.
[0017]
The receiving line may be a table, but considering the case where a large number of work pieces are fed one after another, it is preferable that the receiving line be constituted by a conveyor made up of free rollers. This receiving line may be provided over the entire width in the width direction of the transport line, or may be configured to move with the movable table.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on specific examples shown in the accompanying drawings. FIG. 1 shows a preferred embodiment of a cutting device according to the present invention. The cutting apparatus of this example includes a conveyance line 10, a movable table 20, and a receiving line 30.
[0019]
In the transport line 10, a frame 11 is fixed on the floor surface, and a plurality of transport conveyors 12 are arranged on the frame 11 so as to extend in parallel with each other in the longitudinal direction. In each of the plurality of conveyors 12, drive rollers are appropriately arranged on the start side, the middle, and the end side, while free rollers are arranged therebetween, and the drive rollers are driven by a drive motor or other drive source (not shown). It is designed to rotate.
[0020]
A movable table 20 is provided on the end side of the transport line 10 in the transport direction. A wheel (not shown) is provided at the lower end of the leg of the movable table 20, and a drive motor and other drive sources (not shown) are mounted on the lower side of the movable table 20, and the movable table 20 is driven as described above. The vehicle travels in a direction orthogonal to the conveying direction. In addition, you may make it provide a guide rail on a floor surface so that the movable table 20 drive | works stably.
[0021]
A known saw blade type cutting machine 21 is mounted on the movable table 20, and a known clamping mechanism, for example, a hydraulic cylinder type clamping mechanism 22 is provided between the cutting machine 21 and the conveying line 10. A long workpiece W fed from the line 10 is gripped. Since the structures of the cutting machine 21 and the clamp mechanism 22 are not directly related to the present invention, detailed description thereof will be omitted.
[0022]
A receiving line 30 is provided on the side opposite to the conveying line 10 when viewed from the movable table 20. In this receiving line 30, wheels are provided at the lower leg ends of the frame 31, and a drive motor and other drive sources (not shown) are provided in the frame 31. The frame 31 is orthogonal to the workpiece conveyance direction by the drive source. It is designed to travel in the direction to do. A guide rail for traveling the frame 31 may be provided.
[0023]
On the frame 31 of the receiving line 30, two conveyors 32, 32 are arranged in parallel with each other and extending in the longitudinal direction. The conveyor 32 is configured by arranging free rollers, so that the received work pieces can be conveyed freely.
[0024]
For example, when a work piece having a cross-sectional plate shape, a work piece having a hollow cross-sectional shape, a work piece having a square cross section, and a work piece having an L-shaped cross section are required in small amounts, they are arranged in parallel as shown in FIG. A long workpiece W1 having a flat cross-sectional shape, a long workpiece W2 having a hollow cross-sectional shape, a long workpiece W3 having a square cross-section, and a long workpiece W4 having an L-shaped cross-section are disposed on each of the plurality of conveyors 12. Use a crane, hoist or the like to mount it in advance or during cutting work.
[0025]
Next, the movable table 20 is stopped by traveling to the position of the conveyor 12 on which the long workpieces W1 to W4 to be cut are mounted, and the receiving line 30 is also driven in synchronization with the movable table 20, After the long workpieces W1 to W4 are fed to the movable table 20 by a predetermined size by the conveyor 12, and clamped by the clamping mechanism 22, the long workpieces W1 to W4 are cut by the cutting machine 21, and the obtained workpiece pieces are received. Since it is fed onto the line 30, the clamp is released.
[0026]
At that time, if the position of the movable table 20 in the width direction can be finely adjusted by the operator's pushing and pulling after the traveling is stopped, it is possible to prevent the long workpieces W1 to W4 from being damaged by the clamp and to avoid product defects.
[0027]
If work pieces having the same cross-sectional shape are required, the movable table 20 may be stopped at the same position, the long works W1 to W4 may be fed by a predetermined dimension, clamped and cut.
[0028]
Further, when work pieces having different cross-sectional shapes are required, the movable table 20 and the receiving line 30 are stopped by traveling to the position of the conveyor 12 on which the long work pieces W1 to W4 having the cross-sectional shapes are mounted. Clamping and cutting may be performed.
[0029]
As described above, the cutting operation can be performed very efficiently when cutting a wide variety of work pieces little by little. In addition, using a crane or a hoist, the long workpiece can be mounted on the conveyor in advance or during cutting of another long workpiece, and the burden on the operator is extremely small.
