[0002]

2. Description of the Related Art An example of extrusion equipment for extruding a metal material will be schematically described with reference to FIG. The extrusion equipment has an extruder 1 and a rear surface treatment equipment 2. The rear surface treatment equipment 2 includes a platen pre-cutting machine 3, an initial table 4, a runout table 5, which are successively provided on the extrusion side of the extruder 1, a puller 6 which reciprocates along the runout table 5, and Adjacent to the run-out table 5 is a direction perpendicular to the extrusion direction (arrow a direction) (arrow b).
Direction), a cooling table 7, a stretcher table 8, a transport table 9, and a saw table 10, which are successively provided, a stretcher 11 provided on both sides of the stretcher table 8, and a feed side of the saw table 10. A cutting machine 12 and the like are provided. The cooling table 7, stretcher table 8, and transport table 9 are composed of a plurality of belt conveyors, and the saw table 10 is composed of a plurality of drive rollers.

The extrusion equipment described above operates as follows.
The heated metal material is hot extruded by the extruder 1. The extruded material extruded from the extruder 1 is pulled by the puller 6 while applying a constant tension, and is extruded on the runout table 5 via the initial table 4.
When extruded to a predetermined length, extrusion is stopped and the extruded material is cut by the platen pre-cutting machine 3. The cut extruded material is moved by driving the puller 6 or the run-out table 5 to align the head-side end portion. The grip of the tail end of the extruded material by the puller 6 is released, the extruded material on the runout table 5 is transferred to the cooling table 7 by overlifting, and the cooling table 7 is driven to extrude the extruded material in the extruding direction ( The sheet is conveyed in a direction perpendicular to the direction of arrow a) (direction of arrow b). The extruded material on the cooling table 7 is cooled by forced air cooling with a fan.

The cooled extruded material is conveyed to the stretcher table 8. This extruded material is stretcher 1
No. 1 pulls in the longitudinal direction and bends and cools by cooling. For example, the tail stock 11a and the head stock 11b hold both ends of the extruded material in the longitudinal direction, and one stock is moved in a direction away from the other stock to pull the extruded material. After this, the extruded material is conveyed to the saw table 10 by the conveying table 9, the saw table 10 is driven to send the extruded material in the direction of arrow c, and the cutting machine 12 cuts the set length.

As described above, both ends of the extruded material on the run-out table 5, which has been gripped and released by the puller 6 and has been cut, that is, the extruded material that has been extruded, are free. On the other hand, the extruded material is cooled immediately after extruding and heat shrinkage starts. In addition, a long extruded material having an irregular cross section does not have uniform heat shrinkage in the cross sectional direction. For this reason, the extruded material having the above-described long and irregular cross section is bent and warped before the stretcher 11 grips the head-side end and the tail-side end.

As described above, the extruded material that is bent or warped may have the head-side end portion and the tail-side end portion that are not aligned in the conveying direction, and may not be gripped by the stretcher 11. . In this case, the stretcher 11 is capable of gripping the head-side end portion and the tail-side end portion of the extruded material by a manual operation of the operator. Therefore,
Bending or warping of the extruded material is a hindrance to automation of the post-processing work of the extruded material.

Various extrusion equipments have been proposed which are capable of reducing the above-mentioned bending and warpage of the extruded material. For example, the extrusion equipment disclosed in Japanese Patent No. 2665702 has been proposed. Specifically, grip the end of the extruded material on the head side, run in the extrusion direction in cooperation with the puller, and then run the head clamp that runs to the stretcher along the traverse table and the tail side end of the extruded material. It is equipped with a tail clamp that grips and travels to the stretcher, and by transporting it to the stretcher while holding the head side end and tail side end of the extruded material with the head clamp and tail clamp, Reduces bending and warping.

[0008]

The head clamp described above includes a first traveling guide suspended on the ceiling along the extrusion line, a second traveling guide suspended on the ceiling along a traverse table (cooling table), and a second traveling guide. It is composed of a slider attached to the first and second traveling guides, a clamp body provided on the slider so as to be movable up and down by a lifting cylinder.
For this reason, vibration may occur when the slider moves from the first traveling guide to the second traveling guide, and the vibration is transmitted to the extruded material being held, and the extruded material interferes with the traverse table (cooling table). May hurt you.

By combining the above movements, the end portion of the extruded material on the head side can be continuously held halfway through the first cooling table 7a. Further, by swinging the arm 29 up and down and rotating the main body 33 (grasping portion 13a) about the horizontal axis with respect to the arm 29, the first and second gripping pieces 35 and 36 are moved to the position directly below the one shown in FIG. It can be in a facing posture or a diagonally downward posture. Therefore, it is possible to grip and release the extruded material having any cross-sectional shape, and surely grip the extruded material having any cross-sectional shape.

The tail side holding device 14 will be described with reference to FIGS. A moving body 14a that reciprocates in the pushing direction (direction of arrow a) at a position above the first cooling table 7a, a multi-joint arm member 14b attached to the moving body 14a, and the multi-joint arm member 1

The specific shape of the moving body 14a will be described.
A horizontal member 41 is fixed to a plurality of columns 40 provided upright on the base 20, and an auxiliary member 42 is attached to the lower surface of the horizontal member 41. A pair of guide rails 43 are attached to each of the auxiliary members 42. The guide rail 43 faces the extrusion direction and is located above the first cooling table 7a. The movable body 14a has a horizontal portion 44 and a pair of vertical portions 45, and has a substantially U-shape facing upward. The upper guide roller 46 and the lower guide roller 47 attached to each vertical portion 45 contact the upper and lower surfaces of the guide rail 43. There is. A rack 48 is continuously attached to the lower surface of the one guide rail 43 in the longitudinal direction. A moving motor 49 is attached to the moving body 14 a, and a pinion 50 rotated by the moving motor 49 meshes with the rack 48. Therefore, by rotating the pinion 50 with the moving motor 49, the moving body 14 a reciprocates along the guide rail 43 in parallel with the pushing direction.

A concrete shape of the multi-joint arm member 14b will be described. A swinging body 51 mounted on the lateral portion 44 of the moving body 14a so as to be rotatable about a vertical axis, a first arm 52 mounted on the swinging body 51 so as to be vertically swingable, and a vertical swinging motion on the first arm 52. A second arm 53 freely attached and a third arm 54 rotatably attached to the second arm 53.
And a fourth arm mounted on the third arm 54 so as to be vertically swingable.
The arm 55, a rotary shaft 56 rotatably attached to the fourth arm 55, and a motor (not shown) that swivels, vertically swings, and rotates the arm 55 constitute an articulated arm member 14b.

The grip portion 14c has a main body 57 attached to the rotary shaft 56, a first grip piece 58 and a second grip piece 59 attached to the main body 57. The first grip piece 58 is fixed, and the second grip piece 59 moves in the grip direction and the grip release direction. The first and second grip pieces 58, 59 may be moved in the grip direction and the grip release direction.

Because of this, the articulated arm member 1
By operating 4b, the gripping part 14c can be moved in parallel from the first position on the runout table 5 side to the second position in the middle of the first cooling table 7a. Further, by operating the articulated arm member 14b, the first and second gripping pieces 58,
It is possible to set 59 to the position shown in FIG. Therefore, the tail side end of the extruded material on the runout table 5 is grasped by the grasping portion 14c, and the operation of the articulated arm member 14b is controlled when the extruded material is conveyed by the first cooling table 7a.
By moving in parallel with the conveyance of the first cooling table 7a, it is possible to continue gripping to the second position. In addition, since it is possible to grip and release the extruded material having any cross-sectional shape, it is possible to reliably grip the extruded material having any cross-sectional shape.

Next, the operation will be described. The extruded material is extruded onto the runout table 5 while being pulled by the puller 6, and when the extruded material is extruded to a predetermined length, the puller 6 is stopped. The moving body 14a aligns the grip portion 14c of the tail side holding device 14 with the tail side end portion of the extruded material, and the grip portion 14c.
The tail end of the extruded material is gripped with c. For example, in FIG.
As shown in, the first and second gripping pieces 58 and 59 are set in the vertical posture, and the tail side end portion of the extruded material on the runout table 5 is gripped. The puller 6 releases the grip of the extruded material,
It retreats upward and moves to the extruder 1 side. The extruded material is cut by the platen pre-cutting machine 3, and the moving body 14a is moved in the extruding direction to align the head side end portion of the extruded material. As a result, the puller 6 can be moved to the extruder 1 immediately after the extrusion of the extruded material is completed, so that the extrusion work efficiency is improved.

The head side end of the extruded material is held by the holding portion 13a of the head side holding device 13. For example, as shown in FIG. 2, the first and second gripping pieces 35, 36 are set in a vertical posture, and the head side end portion of the extruded material on the runout table 5 is gripped. As a result, the head-side end portion and the tail-side end portion of the extruded material on the run-out table 5 are respectively gripped. After this, the extruded material on the runout table 5 is transferred to the first cooling table 7a. For example, the run-out table 5 is lowered to the first cooling table 7
When it is transferred onto a, the arm 29 is swung downward while moving the moving body 22, and the gripping portion 13a is rotated to descend the first and second gripping pieces 35 and 36 in a straight line. Similarly, when the run-out table 5 is lowered and is transferred onto the first cooling table 7a, the articulated arm member 1
4b is operated to lower the grip portion 14c straight.

After the extruded material is transferred to the first cooling table 7a, the first cooling table 7a is driven to convey the extruded material. At the same time, the moving body 22 is moved to the first
By moving in synchronization with the cooling table 7a, the grip portion 13a moves in synchronization with the first cooling table 7a. Similarly, when the extruded material is conveyed on the first cooling table 7a, the articulated arm member 14b is operated to move the gripping portion 14c in parallel with the extruded material in synchronization. By doing so, the head side end and the tail side end of the extruded material conveyed by the first cooling table 7a can be continuously held. After the extruded material has been conveyed to the middle of the first cooling table 7a, the first cooling table 7a and the grips 13a and 14c are stopped. The above state is maintained until the next extruded material is extruded onto the runout table 5, and the head side end and the tail side end of the extruded material are continuously held.

In this way, when the extruded material is conveyed from the run-out table 5 to the middle of the first cooling table 7a, the head-side end portion and the tail-side end portion of the extruded material are continuously gripped, so that the extruded material due to heat shrinkage. Bending and warping can be reduced. When the extruded material is conveyed after the middle of the first cooling table 7a, the head-side end and the tail-side end of the extruded material are in a free state, so that some bending and warping occurs. Since the thermal contraction is greatest when the first cooling table 7a is conveyed partway, the bending and warpage can be greatly reduced if the first cooling table 7a is gripped during the conveyance. The time for gripping the extruded material is set appropriately. Further, the extruded material may be gripped partway through the second cooling table 7b.

As described above, by gripping the head-side end portion and the tail-side end portion of the extruded material respectively, when the bending and warpage of the extruded material due to the heat shrinkage are prevented, the heat shrinkage of the extruded material is large. When an attractive force equal to or greater than a certain attractive force acts between the side holding device 13 and the tail side holding device 14, the articulated arm member 14b operates and the grip portion 14c can move to the head side. That is, the movable part such as the arm of the multi-joint arm member 14b is held by the electric motor so as not to move, and moves when an external force equal to or greater than the holding force acts. Therefore, excessive force is not applied to the extruded material, and the cross-sectional shape does not change.

Further, the grip portion 13 of the head-side holding device 13
a rotates around the horizontal axis with respect to the arm 29, and the gripping portion 14c of the tail side holding device 14 rotates around the horizontal axis by the multi-joint arm member 14c, so that the first cooling table 7a.
During the process, the extruded material can be turned over 90 degrees. For example, as shown by the phantom line in FIG. 2, the moving body 22 is moved to the middle of the first cooling table 7a, and as shown by the phantom line in FIG. 5, the grip portion 14c is moved to the middle of the first cooling table 7a. . In this state, the first cooling table 7a is stopped. The main body 33 with the rotation motor 34
To rotate the first and second gripping pieces 35, 36 of the gripping portion 13a.
Is in a sideways posture as indicated by a virtual line in FIG. At the same time, the articulated arm member 14b is operated to operate the grip portion 14c.
The first and second gripping pieces 58 and 59 are set to the sideways posture as shown by phantom lines in FIG.

By doing as described above, the extruded material extruded in the vertical orientation is inverted 90 degrees in the horizontal orientation on the first cooling table 7a. Therefore, it is possible to prevent the extruded material from falling down when the extruded material is conveyed after the middle of the first cooling table 7a. That is, the extruded material having a rectangular cross section is extruded in a posture in which the short side is horizontal and the long side is vertical, that is, the vertical orientation, in order to reduce the area in contact with the runout table 5. This vertically oriented extruded material is unstable and may fall down when it is conveyed by the cooling table 7. If the extruded material falls down, the surface will be scratched. Therefore, as described above, the extruded material extruded in the vertical orientation is reversed to the horizontal orientation so that it can be stably conveyed.

[0033]

According to the invention of claim 1, the tail side end of the extruded material extruded on the runout table 5 is grasped by the grasping portion 14c of the tail side holding device 14, and the moving body 14a is cut after the extruded material is cut. By moving in the extrusion direction, the extruded material can be moved in the extrusion direction and aligned. After that, the head-side end of the extruded material is gripped by the grip 13a of the head-side holding device 13, and the grip 13a is moved to the moving unit 1.
3b moves to the middle of the cooling table 7, and at the same time, the articulated arm member 1 of the tail side holding device 14 described above.
4g can be operated to move the gripping part 14c to the middle of the cooling table 7. The gripping portion 13a, gripping portion 14c until the next extruded material is extruded onto the runout table 5.
Can be stopped at the above-mentioned position, and the head side end and the tail side end of the extruded material can be continuously gripped.

Thus, the head side end and the tail side end of the extruded material on the run-out table 5 which has been extruded can be gripped, and the extruded material can be conveyed to the middle of the cooling table 7 while being gripped. Therefore, the bending and warping of the extruded material due to the heat shrinkage can be reduced.

Further, the tail side holding device 14 is the moving body 1
As the multi-joint arm member 14b moves in the push-out direction together with 4a, the grip portion 14c moves in the push-out direction, and the multi-joint arm member 14b is operated while the moving body 14a is stopped to move the grip portion 14c to the cooling table 7. Since it moves halfway, the gripping portion 14c can smoothly change the moving direction. Therefore, the extruded material gripped by the gripping portion 14c does not interfere with the cooling table 7 and are not damaged.

According to the second aspect of the invention, the grip portion 13a of the head side holding device 13 rotates about the horizontal axis with respect to the arm 29, and the arm 29 swings up and down with respect to the moving body 22. By doing so, by combining those movements, the gripping portion 13a can grip and release the gripping material corresponding to the extruded material of any cross-sectional shape. Further, the head-side end of the extruded material held by the holding portion 13a can be turned over 90 degrees on the cooling table 7. Further, since the grip portion 14c of the tail side holding device 14 is rotated around the horizontal axis by the multi-joint arm member 14b, the grip portion 14c can be gripped / released in correspondence with extruded materials having any cross-sectional shape. Furthermore, the tail side end of the extruded material gripped by the gripping portion 14c can be turned over 90 degrees on the cooling table 7. Therefore, the extruded material having any cross-sectional shape can be reliably gripped, and the extruded material can be inverted by 90 degrees on the cooling table 7. Therefore, the extruded material extruded in the vertical orientation is placed in the horizontal orientation on the cooling table 7, and thereafter. Can be stably transported.
