Conventionally, when pulling out a strip from a pull-out device, it has been necessary to pass a lobe in advance from a roller at a conveyance end position to a roller at a conveyance start position in the pull-out device.

When the strip reaches the pull-out device after undergoing processes such as heat treatment, the tip of the sent-out strip is tied to the tip of the rope, and the rope is pulled from the conveyance end position to pull the strip into the pull-out device. This is to try to extract it from the

However, there is a need to pass the rope through several rollers from the conveyance end position to the conveyance start position, and to tie the end of the rope to the tip of the strip that has been sent to the bowing device, and to tie it to the end of the rope. The work was very tedious.

[Means for Solving the Problems] Therefore, in order to solve the above problems, the following measures were taken.

The strip pulling device according to claim 1 is provided with an endless chain for conveying the strip from the entrance to the exit of the pulling device, and rollers for guiding the strip from the outlet to the exit. A holding member is installed between the left and right endless chains, the tip of the strip is attached to the holding member, and as the endless chain runs, the strip attached to the holding member is attached to the end of the pull-out device. It is conveyed from the point to the exit.

Further, as in the device for pulling out a strip-shaped article according to claim 2, the holding member includes two cylindrical construction members that clamp the tip of the strip-shaped article and a holding cover, and the two construction members are connected to each other by a connecting member. Pins connected to each other and capable of fitting into pin holes of an endless chain are provided on both sides of the construction crotch member, and the holding cover is plate-shaped, and a cut-and-raised piece for pressing the strip is provided in the center. It is preferable that both opposing end edges be bent in the same direction so as to be able to hold the holding member.

[Function] In the belt-like object drawing device according to claim 1, the leading end of the belt-like object that has been sent out to the drawing device after undergoing a process such as heat treatment is attached to the holding member. Then, the holding member holding the strip is installed on endless chains provided on both left and right sides of the strip travel path. In this state, when the endless chain is driven, the holding member runs, and the strip is guided by the rollers and conveyed from the outlet of the drawing device to the exit. This makes it possible to automatically pull out the strip at the extraction section of the strip processing machine.

In the device for pulling out a strip according to the second aspect of the present invention, the distal end of the strip is wound around the construction member constituting the holding member, and the holding cover is placed over the distal end of the strip.

In this way, the tip of the strip is held between the holding members, and the pins at both ends of the holding member are fitted into the pin holes on both sides of the one pin hole in the link of the endless chain. Install the holding members on the left and right endless chains.

Thereafter, when the endless chain is driven by a drive source such as a motor, the holding section +4 runs accordingly, and the strip is subsequently conveyed from the outlet of the drawing device to the exit. At this time, since the tip of the strip is locked by the cut-and-raised piece provided on the protective cover, the strip will not easily melt. In addition, this holding member is large enough to be attached to the pin holes on both sides of the endless chain, so it can get caught between the chain wheels while running and stop midway. There is no fear that it will.

Thereby, the strip-like material can be drawn out even more effectively in the drawing-out section of the processing machine.

There is no such thing as unraveling from 0 and easily falling off. Furthermore, as shown in FIG. 4, the construction member 70 is large enough to be attached to the pin holes 81 on both sides of the endless chain 22 with one pin hole 81 interposed therebetween.
There is no risk of the chain wheel getting caught between the chain wheels and stopping midway. As the endless chain 22 continues to travel, the leading end of the strip A is sent out to the conveyance end position P.

As described above, according to the present invention, it is possible to automatically perform the opening and closing of the outlet section in the processing machine for strip material A, which has been troublesome until now.

When the leading end of the strip A reaches this conveyance end position P, a stop limit switch (not shown) provided in the vicinity is activated, and the running endless chain 22 is stopped.

As the endless chain 22 runs, the holding cover 71 is removed from the construction member 70 that has been transported to the transport end position P, as shown in FIG. Unwind the tip from the construction member 70. Thereafter, the pins 78 at both ends of the construction member 70 are pulled out from the pin holes 81 of the endless chain 22. This removal can be easily performed by shortening the construction member 70 using the spring action of the cork spring 75.

Then, the tip of the strip A that has been sent out to the conveyance end position itp, which is the exit of the pull-out device 6, and from which the construction member 70 and the holding cover 71 have been removed, is placed inside the front and rear support plates fixed to the support frame. Get into it. When the tip of the strip A reaches this vicinity, the shake-off roller 31 is rotated by a drive source different from the motor that runs the endless chain 22. This rotation causes the shaking-off roller 31 and the holding frame 32 connected by the connecting arm 36, and the support plates 34 and 35 disposed in the front and rear to be rotated.
swings back and forth. As a result, the strip A that has entered the inside of the support plate 34, 35 is shaken off at the rear of the processing machine, and is folded into a ball C placed on the floor. become.

Note that if the construction member To is constituted by two cylindrical rods 73 as in this embodiment, there is no risk that the construction member 70 itself will rotate; however, this is not always necessary, and the construction member 7o It is also possible to construct it by one cylindrical rod 73 and install it on the endless chain 22.

All other embodiments that fall within the scope of the claims are within the scope of this invention.
