Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a workpiece conveyance device for a shearing machine, and more specifically, the present invention relates to a shearing machine having a feeding function at least perpendicular to the direction of conveyance of the workpiece. The present invention relates to a work transfer device for a ring machine.

[Prior Art] Relatively large shearing machines have a return device that pulls in a workpiece plate to a predetermined position before cutting, and pushes it back to the initial feeding device, that is, the front side of the shearing machine, after cutting. Many are equipped with a conveyor piler. A return conveyor piler usually has a plurality of belt conveyors arranged in parallel at the rear of the shearing machine frame, and is fed back and forth by a drive motor.
Further, the rearmost portion is a drive pulley, and the other end, that is, the end on the cutting blade side, can swing up and down using the pulley shaft as a fulcrum.

This raises the belt conveyor to the pass line level of the workpiece and pulls the workpiece into a predetermined position. Next, the belt conveyor is lowered to perform the cutting, and the belt conveyor carrying the cut plate is raised to the above-mentioned level. Then, the belt conveyor is operated to push the cut plate material back to the front side of the shearing machine, unload it, and then accept the next workpiece again.

[Problems to be Solved by the Invention] However, although the return conveyor piler transports the workpiece in the front-back direction, it cannot move the workpiece in any other direction. Therefore, when the workpiece is thick, large in size, and heavy, it is extremely difficult to pull the workpiece in a direction perpendicular to the conveyance path, that is, to the side, for the purpose of checking the details of the cut portion of the workpiece, for example. Furthermore, so-called feed-cutting, in which the workpiece is moved along the length of the cutting blade to perform a cut longer than the length of the cutting blade, is extremely difficult unless the workpiece is extremely lightweight.

The purpose of this invention was to solve the problems of the conventional devices mentioned above, and was developed to create a shearing machine that can easily carry out so-called lateral feeding perpendicular to the conveyance direction of the return conveyor piler by means of structural improvements. The present invention provides a workpiece conveyance device.

[Means for solving the problem] In order to achieve the above object, the present invention provides a beam member that is movable up and down at a rear position of a cutting section consisting of an upper blade and a lower blade of a shearing machine. A plurality of belt conveyors arranged in parallel in the longitudinal direction of the lower blade are supported, and a plurality of rotary body support members each having a rotary body on an upper surface are supported on the beam member between each of the belt conveyors. The rotating body support members are provided to be movable up and down so that the rotating bodies can freely move in and out of the upper surface of the belt conveyor.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

Referring to FIGS. 1 and 2, a plurality of front and rear blades are provided between the left and right machine frames 9 at the rear (on the right side in FIG. 1) of the cutting section 7 by the upper blade 3 and lower blade 5 of the shearing machine 1. For example, five small belt conveyors 11 as conveying devices are arranged in parallel. Each belt conveyor 11 is lined up with a slight gap 13 along the conveyance direction of the workpiece W.
A beam member 17 of the conveyor frame 15 is arranged in each gap 13.

Each belt conveyor 11 has a conveyor frame 15
A drive pulley 21 is pivotally supported on a column 19 at the rearmost part (rightmost side in FIG. 1). The top pulley 23 near the cutting section 7 swings up and down about the shaft of the drive pulley 21 as a fulcrum by a drive cylinder mechanism 25 connected between the upper part of the beam member 17 and the conveyor frame 15. When the drive cylinder mechanism 25 is operated to raise the top pulley 23, the belt surface 27 of the belt conveyor 11 is at the same level as the pass line of the workpiece W, that is, the front table 29 surface of the shearing machine 1.

When the drive pulley 21 is rotated clockwise in FIG. 1 in the above state, the belt conveyor 11 pulls the workpiece W to a predetermined position. Next, the drive cylinder mechanism 25 is operated to lower the top pulley 23 and the work W is cut, and the cut plate material is received by the belt conveyor 11. Now top pulley 2
3 and rotates the drive pulley 21 counterclockwise in Fig. 1, the cutting plate material is moved to the front table 2.
Pushed back to the 9 side.

Each gap 13 of the belt conveyor 11 configured as described above
A box 31 serving as a rotating body support member is provided on the side of the cutting section 7. Furthermore, a drive device 33 for moving the box 31 up and down is provided at the lower rear side of the box 31. More specifically, the third
As shown in FIGS. 4 and 5,
On the top surface of the box 31, as shown in FIG. 5, free bearings 35 as rotating bodies are arranged in three rows, and as shown in FIGS. 3 and 4, five free bearings are arranged in the left and right direction in FIG. It is installed.

The drive device 33 includes an air cylinder 37 that drives the box 31 in the front-back direction and in the left-right direction in FIG.
It is composed of a cam follower 39, a bending groove 41 into which the cam follower 39 is slidably fitted, and a slide guide member 43.

The air cylinder 37 is connected to the beam member 17 and the box 31.
connected between the sides of the Cam follower 3
9 are attached to project from the side surfaces of the beam members 17 on both the left and right sides of the box 31, two on each side of the box 31. Bend grooves 41 into which the cam follower 39 is slidably fitted are provided on both left and right side surfaces of the box 31. The slide guide member 43 smoothly guides the movement of the box 31 in the longitudinal direction.
It is attached to both inner surfaces of the left and right beam members 17 of the box 31.

When the box 31 is pushed forward to the left in FIG. 3 with the air cylinder 37, the cam follower 39
Since the upward slope of the bent groove 41 touches the box 31, the box 31 rises obliquely upward. Eventually, as shown in FIG. 4, the cam follower 39 reaches the horizontal part of the bent groove 41, and the box 31 stops rising. At this time, the top level of the free bearing 35 is set to be about 10 mm above the belt surface 27. When the air cylinder 37 is used to pull the box 31 to the right side in FIG. 4, the box 31 is lowered from the highest level in FIG. 4 to the lowest level in FIG. 3 in the opposite manner. At this time, the top level of the free bearing 35 is sufficiently lower than the belt surface 27.

Therefore, when the belt conveyor 11 is raised and the box 31 is also raised with respect to the workpiece W fed from the front table 29 of the shearing machine 1, the workpiece W is substantially supported by the free bearing 35. As a result, the workpiece W can be easily moved by hand on the free bearing 35 back and forth, left and right, and diagonally. If only the belt conveyor 11 is raised without raising the box 31, it goes without saying that the belt conveyor 11 can pull in the workpiece W and push back the cut plate material as before.

Note that when the box 31 is raised again as shown in FIG. 4, the vertical load due to the support of the workpiece W is applied to the cam follower 39 through the horizontal portion of the bending groove 41, so that no load is always applied to the air cylinder 37 side. . Box 31 when moving and placing the workpiece W on the free bearing 35 and the belt surface 27
The axial component of the vertical load acts on the air cylinder 37 only for a very short period of time during elevation.

The belt conveyor 11 and the box 31 are both raised to support the workpiece W on the free bearing 35 and move it back and forth and left and right to position it. After positioning, both the belt conveyor 11 and box 31 are lowered in preparation for cutting. The cut plate material now falls onto the belt conveyor 11 and is received. Next, the belt conveyor 11 is raised again,
The return conveyor is driven as a piler and takes out the cut plate material to the front table 29 side.

Also, when performing the feed end on the long planned cutting line, the belt conveyor 11 and the box 31 that were lowered during the previous stage of cutting are raised again, and the workpiece W is fed horizontally as described above. do. Then, the belt conveyor 11 and box 31 are lowered to perform the next cutting. Thereafter, repeat the above operation until the cutting is completed. The horizontally long plate material that has been cut in this way is taken out to the side by raising the belt conveyor 11 and the box 31 and using the free bearing 35.

In the case of this embodiment, since the free bearing 35 is used as the rotary body, the movement direction of the workpiece W is not only the direction perpendicular to the original transport direction of the conveyor line, that is, the transverse direction, but also the transport direction, i.e. It can be easily moved by hand in any direction, including front and back and diagonally.

As described above, according to the apparatus of the present embodiment, it is possible to move the workpiece W in the lateral direction perpendicular to the conveyance direction of the conveyor line even for a workpiece W having a weight exceeding a certain level, that is, a weight exceeding a weight that is difficult to lift and move by hand. It can be done easily and easily. Therefore, it becomes possible to check the details of the cut portion and finish the feed, which were extremely difficult with the conventional device, very easily, quickly and safely.

The device of the present invention is not limited to the above-mentioned embodiment, but can be modified in various ways. For example, a caster roll may be used instead of a free bearing as a rotating body. Alternatively, ball bearings or roll bearings may be arranged and mounted on the box 31 with their axes aligned with the conveyance direction of the conveyor line.

Alternatively, instead of the combination of the bending groove 41 and the cam follower 39, the box 31 may be raised and lowered by connecting the box 31 and the beam member 17 with two parallel links on the left and right sides. Moreover, even if a roll conveyor is used instead of a belt conveyor as a front-back conveyance device, the same function can be achieved by applying the present invention in the same manner.

[Effects] As can be understood from the above description of the embodiments, the present invention provides a shearing machine with an upper blade 3 and a lower blade 5, which are provided in a rear position of the cutting part 7, which is movable up and down. The beam member 17 is provided to support a plurality of belt conveyors 11 provided in parallel in the longitudinal direction of the lower blade 5, and a plurality of rotary body support members 31 each having a rotary body 35 on the upper surface are attached to each of the belt conveyors 11. The rotary body support members 31 are supported by the beam member 17 between the belt conveyor 11 and the rotary body support members 31 are vertically movable so that the rotary bodies 35 can freely move in and out of the upper surface of the belt conveyor 11. be.

As is clear from the above configuration, in the present invention, the rotating body support member supporting the rotating body 35 is
It is vertically movably supported by a vertically movable beam member 17 that supports a plurality of belts 11.
Therefore, according to the present invention, even when the belt conveyor 11 is lowered below the pass line, the rotating body 35
It is something that can make people appear. Therefore, the plate material that has been sheared and fallen by the upper blade 3 and lower blade 5 of the shearing machine is transferred to the belt conveyor 11.
The rotating body 35 does not get in the way when the belt conveyor 11 is raised to the pass line and the plate material is sent back to the front side again. Moreover, in the state where the rotating body 35 is made to protrude from the belt conveyor 11,
Since the portion of the plate that protrudes rearward from the lower blade 5 is supported, it is possible to easily shear the plate while feeding it in the longitudinal direction of the lower blade 5.
