Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extruder profile drawing device for drawing a profile extruded from an extruder.

[0002]

2. Description of the Related Art A mold material extruded from an extruder is clamped by a clamper provided on a puller of a mold material pulling device and is pulled by moving the puller to be drawn out on a runout table while maintaining a straight state.

As such a mold material pulling device, as shown in, for example, Japanese Patent Application Laid-Open No. 2-274309, a puller is reciprocally provided along a rail, a clamper is attached to the puller, and the puller is wound around a driving wheel and a driven wheel. The hanging wire rope was connected to the puller, and the puller was used as a driving device.The puller was returned to the extruder side to clamp the extruded mold material with a clamper, and in this state, the puller was moved forward to pull out the mold material. Things are known.

[0004]

The extrusion speed of the extruder is increased by increasing the reciprocating speed of the puller of the die member pulling device, or the productivity of the extruder is improved by providing two pullers facing each other. it can. However, when a cutting machine is installed on the extrusion side of the extruder and the mold material is cut by the cutter after the mold material is pulled out by the puller, the cutting operation is performed when the puller that has moved forward to the drawer end position is returned to the extruder side. It may interfere with the cutting machine of the machine, stop and wait the puller at a position where it does not interfere with the cutting machine, and after the cutting machine completes cutting, move the puller to the extruder side and use the clamper as the clamp position The mold material is pulled out by clamping the tip of the and moving forward.

For this reason, the puller reciprocating device for reciprocating the puller is stopped when the puller moves to the standby position when the puller is moved back, and when the cutting of the mold is completed, it is re-driven to move the puller to the clamp position. Will stop,
Clamping the puller from the standby position is very difficult because control of the puller drive device is very troublesome, and it is very difficult to move at a high speed due to the short distance from the standby position to the clamp position and to stop correctly at the clamp position. The moving speed to the position becomes slow, and the moving speed of the entire puller becomes slow, so that the productivity of the extruder deteriorates.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a die material traction device for an extruder which can solve the above-mentioned problems.

It is attached to 15. That is, the bracket 16 is attached to each of the pair of connecting members 14, 14, and the rocking body 17 is supported between the brackets 16 so as to be rockable left and right by the horizontal shaft 18, and the lever 19 provided on the lower part of the rocking body 17 and The rocking cylinder 20 over the cross member 13 of the pin 2
1 and 22, and a cylinder 23 is attached to the upper part of the oscillating body 17 so as to face the mold material extrusion direction.
A stopper piece 24 is attached to the third piston rod 23a.

Because of this, the rocking cylinder 20
When the oscillating body 17 is contracted to the standing posture shown in the drawing, the stopper piece 24 comes to a non-stop position separated from the puller 5, and the oscillating body 20 is extended to oscillate the oscillating body 17 so that the oscillating body 17 is in an oblique posture. Is the stop position facing the puller 5. Further, by extending and contracting the piston rod 23a of the cylinder 23, the stopper piece 24 moves in the die material pushing direction so that the stop position, that is, the standby position of the puller 5 can be adjusted.

As shown in FIGS. 4 and 5, the auxiliary drive unit 8 includes a pair of intermediate vertical members 3 forming the frame assembly 2.
It is mounted on a mounting cross member 31 which is installed horizontally at 0 and 30. That is, the one-side bracket 32 and the other-side bracket 33 are attached to the longitudinal surface 31a of the mounting horizontal member 31 at positions near both ends in the longitudinal direction, and the drive wheel 34 is rotatably supported by the vertical axis 35 on the one-side bracket 32. The driven wheel 36 of the side bracket 33 is rotatably supported by the vertical axis 37, and the chain 38 is wound around the drive wheel 34 and the driven wheel 36.

The cutting machine 9 has a base 50 as shown in FIG.
A movable body 51 is movably attached to the movable body 51, and a rotary blade 52 is rotatably attached to the movable body 51. By advancing the movable body 51, the extruded mold material A is cut by the rotary blade 52. When 51 is moved backward, rotary blade 52 and clamper 6
I try not to interfere.

Next, the operation will be described. After the mold material A is clamped by the clamper 6 of the puller 5 and the puller 5 is moved forward at high speed to complete the drawing, the movable body 51 of the cutting machine 9 is advanced to cut the mold material A by the rotary blade 52. At the same time, the rocking cylinder 20 is extended and the frame 17 is rocked to move the stopper piece 24 to the stop position facing the puller 5 and return the puller 5 at high speed. At this time, the pushing piece 39 of the auxiliary drive device 8 is in the position shown by the alternate long and short dash line in FIG. 4, that is, the position in which the switch 44 is turned on and the motor 41 is stopped.

As a result, the puller 5 comes into contact with the stopper piece 24 and stops at the standby position shown by the alternate long and short dash line in FIG. 4, and the clamper 6 is prevented from interfering with the cutting machine 9 during the cutting operation.

When the cutting machine 9 has finished cutting the mold material A, the movable body 51 is moved backward and at the same time the swing cylinder 20 is contracted to bring the stopper piece 24 into the non-stop position, and the motor 41 is driven to rotate and push the chain 38. The piece 39 is moved to the extruder 1 side along the guide 43, whereby the puller 5 is moved to the clamp position shown by the chain double-dashed line in FIG. It abuts 46 and stops. As a result, the motor 41 rotates in the reverse direction, the chain 38 rotates in the reverse direction, the pushing piece 39 moves in the opposite direction to the above, and when it comes to a position where it does not interfere with the receiving piece 40, the switch 44 is turned on, whereby the motor 41 stops. .

When the clamper 6 clamps the mold material A in the above-mentioned state, the puller 5 is moved forward at high speed to pull out the mold material A.

Since the puller 5 is moved from the standby position to the clamp position by the auxiliary drive device 8 in this way,
Can be quickly moved from the standby position to the clamp position,
Since the puller 5 moves forward at high speed by the drive device and returns to the standby position at high speed, the overall moving speed of the puller can be increased, and the drive device of the puller 5 can be controlled to drive at high speed and stop. The control becomes easy.

Further, since the pair of pullers 5 is provided in the embodiment, the pair of pullers 5 can be alternately moved forward and backward to pull out the mold material A, so that the mold material A can be efficiently drawn out.
