Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a long strip-shaped steel material, a long strip-shaped aluminum material, or the like, which is used to remove the edge of the tip of the long strip-shaped material. Material edge processing equipment.

[Conventional technology]

When winding long strips such as long strips of steel and long strips of aluminum into a coil in a tight and tight manner (for example, after rolling the long strips, coil them in order to make a package for the user. In the case of winding, the edge of the leading end of the long strip of material bites into the inner surface of the long strip of material wound thereon, causing a situation in which the surface is flawed.

In order to avoid such a situation, there is a method of artificially removing the edge of the front end portion of the long strip-shaped material by using a grinder before winding the long strip-shaped material. The work of removing artificially by using a grinder requires skill in order to perform it with high accuracy, and is extremely troublesome and has poor workability.

Therefore, conventionally, a clamp device that presses the tip side of the work downward from above is provided, and the tip side of the work is supported by a guide roller from below,
Using a grinding cutter that can move laterally in the direction perpendicular to the work traveling direction, mechanically process the edge of the tip using a steel plate tip grinding device configured to chamfer the work tip. It has also been attempted (see, for example, JP-A-63-237858).

[Problems to be Solved by the Invention]

In the conventional structure that performs the above mechanical processing, it is advantageous in that the removal of the tip edge that requires a great deal of work can be efficiently performed by using the mechanical force, but in this conventional structure, There are the following problems.

That is, the tip portion of the long strip is usually deformed in the thickness direction of the strip, and on the production line, it is cut in a certain length on the good side. It is usually conveyed, and from these facts, the leading end of the long strip is deformed in the thickness direction, or the leading edge is completely in the transport direction of the long strip. It may be sent in an inclined state instead of in an orthogonal posture.

The deformation of the long strip in the thickness direction can be solved to some extent by using the clamp device pressing from above and the guide roller supporting from below. When the thickness of the strip-shaped material is large or the amount of deformation is large, if a strong pressing force is applied to eliminate the deformation, the surface may be damaged. Conversely, if the pressing force is weak, the deformation cannot be resolved. It may be cut as it is and the edge of the tip may remain in the part.

Further, the edge of the long strip cannot be clamped by the upper and lower clamps or rollers even at a position very close to the tip of the end of the strip to be processed.
It is always held in a state of slightly protruding from the holding position. For this reason, if the long strip is thin, it will bend in the longitudinal direction if it is pressed too strongly near the tip with a processing device. Is required. However, the thinner the product, the more likely it is to deform in the thickness direction, and it is also a very difficult technique to accurately control and set the vertical position of the processing device so as to reliably cut the edge of the thin long strip. This is a major obstacle to enabling mechanical processing of edges.

Furthermore, when the long strip-shaped material is fed in a state where its leading edge is not orthogonal to the traveling direction, only a part of the leading edge can be removed, and many edges remain. There was also the problem of being lost.

In the present invention, the edge of the tip of the long strip is efficiently used by using mechanical force, and further, the thickness of the long strip, the degree of deformation of the tip in the thickness direction, or the long strip. The purpose is to enable accurate removal regardless of the presence or absence of the inclination of the leading edge with respect to the transfer direction.

[Means for solving the problem]

The technical means of the edge treatment equipment for a long strip-shaped material according to the present invention, which has been taken to achieve the above-mentioned object, is to position the tip end in the longitudinal direction of the long strip-shaped material, and then clamp the vicinity of the tip end in both thickness directions. And a carriage that moves in the width direction of the long strip along the front end of the long strip whose end is sandwiched by the sandwiching device. Accordingly, a processing device that processes and removes the edge of the tip portion is provided on the carriage via a holding device that holds the edge, and the holding device includes an elastic holding portion mounted on the carriage side and a processing device side. The elastic holding portion is constituted by a combination with a guided portion, and the elastic holding portion is balanced by an upward elastic biasing force of the coil spring and a downward biasing force of the drive cylinder. The processing device is configured to elastically hold the long strip material so as to be displaceable in the thickness direction, and the guided portion is deformed in the thickness direction with respect to the elastic holding portion. Further, the guided portion is attached to the elastic holding portion so as to be rotatable about a pivot axis along the thickness direction of the long strip-shaped member, and the long portion. The urging force is applied by the urging means from the front end side of the strip-shaped material in the longitudinal direction, so that the processing device is brought into contact with the front end surface of the long strip-shaped material. .

[Work]

The effect of taking the above technical means is as follows.

a. Of the holding devices that hold the processing device to the carriage, the elastic holding part that moves with the carriage in the width direction of the long strip is elastically held so as to be displaceable in the thickness direction of the long strip. At the same time, since the guided portion that supports the processing device is linked to the elastic holding portion so as to follow the deformation in the thickness direction, the long strip-shaped material is deformed in the thickness direction. Even if there is a problem, the processing apparatus can be moved up and down in the thickness direction following this.

b. Elastic holding of the processing device by the elastic holding portion is performed by a balance between the weight of the processing device itself, the upward elastic biasing force of the coil spring, and the downward biasing force of the drive cylinder. Therefore, the appropriate position adjustable range of the processing device in the thickness direction of the long strip to be processed can be set large.

In other words, in the case where the processing device is simply lifted and supported by the coil spring, the position where the apparent weight of the processing device with respect to the long strip-shaped material becomes zero is the vertical direction when the tension of the coil spring is in balance with the processing device weight. However, if the level changes even a little from now on, the weight of the processing equipment will be heavily loaded on the processing target part of the long strip, and excessive pressing may occur. . Further, in the case of lifting and supporting the processing device by simply using the drive cylinder (in this case, the direction of the force acts upward), the position control of the processing device by the drive cylinder is used for the edge forming portion of the long strip-shaped material. It is extremely difficult to do exactly so that the level is accurately matched.

Compared with these, in the present invention, since the expansion and contraction amount of the drive cylinder is controlled so that the coil spring is extended according to the level of the long strip-shaped material, that is, the tension of the coil spring and the downward biasing force ( The level of the balance between the weight of the processing device and the urging force of the drive cylinder)
Since the level can be adjusted according to the level of the long strip to be processed, the level adjustment range can be set broadly.

Moreover, due to deformation of the long strip in the thickness direction,
Even if the position of the end of the long strip fluctuates up and down a little, the vertical position of the processing device is not completely fixed, but is determined by the balance with the tension of the coil spring. Therefore, it is not necessary to strictly control the vertical position of the processing device even if the amount is small, and to move it. Therefore, there is an advantage that the position control of the processing device becomes simple.

c. The guided portion on the side supporting the processing device is rotatably attached to the elastic holding portion attached to the carriage about a pivot axis along the thickness direction of the long strip-shaped material. Further, since the urging force is applied by the urging means from the front end side in the longitudinal direction of the long strip-shaped member, the long strip-shaped member is tilted so that its leading edge is not orthogonal to the transfer direction. Even when it is sent, the guided portion can be rotated around the pivot shaft axis so as to match the inclination of the tip edge, and the processing device can be moved in the direction of the tip edge.

〔The invention's effect〕

The effects of taking the above technical means are as follows.

That is, even if the long strip-shaped material is deformed in the thickness direction, the processing device can be moved up and down in the thickness direction without a large change in the pressing force against the long strip-shaped material. Even if the strip-shaped material is slightly deformed in the thickness direction, the edge can be reliably formed. Moreover, the vertical position of the processing apparatus can be easily adjusted without requiring strict control.

Further, even if the long strip-shaped member is fed in a tilted posture in which the leading edge thereof is not orthogonal to the transport direction, the guided portion is moved around the pivot shaft axis in a state of matching the tilt of the leading edge. Since the processing device can be moved along the direction of the tip edge while rotating, there is an advantage that the edge can be removed efficiently and surely without the inconvenience of damaging the long strip.
