Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an end face alignment device for aligning the end faces of steel pipes, etc., in the final packaging state, and more specifically, the present invention relates to an end face alignment device for aligning the end faces of steel pipes, etc. in the final package. Long timbers with various cross-sections form a cluster and bind together,
This relates to a device that performs end face alignment without noise during the flow process, and enables automation of the entire device.

The long materials are conveyed one by one on a chain conveyor skid parallel to the longitudinal direction for gathering and forming, but the unevenness due to irregularities on the end faces varies by about 50 m. Normally, when they are assembled on the skid, they are pushed with a pusher etc. to reduce the difference in unevenness and then transported to the collecting and forming means.
After formation, a stopper 1 is provided at the edge of the pond as shown in FIG.
Use the pressing machine 2 from the other end to align the pressing end surfaces. In addition, although this is not shown in the drawings, pushers are provided at both ends to simultaneously press. However, in the former case, it is necessary to move the stopper according to the length of the pipe, but this is difficult due to the configuration of the equipment, and manual attachment and detachment is the only option.

In the latter case, after forming, bundling, and moving the material, it is pressed from both sides, but this requires a pusher with a large pressing force, which has the disadvantage of causing scratches on the long material. The present invention eliminates the above-mentioned drawbacks, and in the process of sequentially collecting and sending long pieces of paper for forming, the end face is first aligned almost to the reference position using an end face correction conveyor, and the second correction is made at the forming position. By correcting the formation order for each part, the end faces can be neatly aligned.

The reason why the stopper 1 is required in the method shown in FIG. 1 is that if the pressing machine 2 makes corrections one step at a time, if the amount of correction is large, the movement of the correction material causes the lower member to move as well. In the next correction, most of the alignment is completed at the flow entrance of the long village, and in the second correction, the amount of correction is numerically about 2 meters at the forming position, and other members do not move.

In other words, it has the feature of not requiring a stopper. Embodiments of the apparatus of the present invention will be described below with reference to the drawings.

FIG. 2 is a three-dimensional perspective view of the apparatus, in which 3 is the largest part (for example, a pipe), and it is assembled on skids 4 provided at intervals.

Reference numeral 5 denotes a take-in conveyor that separates and takes in the long materials 3 on the skid 4 one by one, and a plurality of conveyors are arranged in parallel at regular intervals.

6 is an alignment conveyor for sequentially and parallelly taking in the longest materials 3 conveyed from the intake conveyor 5; 7 is a conveyor for correcting the end face of the long materials; and 8 is a conveyor between the alignment conveyors 6 and along the conveyance path. This is an alignment roll that is appropriately placed in the middle of the elongated material 3 so as to be perpendicular to the elongated material 3.

FIG. 3' shows the relationship of the above-mentioned members, in which the end face correction conveyor 7 is installed at the illustrated position on the outlet side of the intake conveyor 5 and the side face of the alignment conveyor 6. is received by a part of the endless conveyor surface that is tilted linearly, and the long material 3 is advanced at a constant speed, and the alignment roll 8 of the arrangement described above is moved to the other end side by the amount of irregularity of the long material 3. It is moved laterally while transferring the upper part, and sent out along the reference line A at the exit side of the end face correction conveyor 7.

Next, the end face correction conveyor 7 will be explained with reference to FIG.
1 is an endless vertical flat chain arranged, for example, in a triangular shape, constituting the end face correction conveyor 7, and 10 is a sprocket wheel, which moves the chain by driving an arbitrary sprocket wheel.

Note that the drive device is branched from the intake conveyor 5 and will not be described in detail. 11 is the conveyor frame, pedestal 1
2, and can be moved by the adjustment amount of the reference position.

13 is a moving screw for the frame 11.

Next, the alignment roll 8 will be described in detail with reference to FIGS. 5 and 7. 14 is an alignment roll shaft, and 15 is a divided roll obtained by dividing the alignment roll, which freely contacts the alignment roll shaft 14. There is.

The reason for this division is that the long material 3, which is moving in parallel at regular intervals, is moved laterally by the end face correction conveyor 7, so the dividing roll rotates by the amount of movement for each piece, and the long material 3 is This is because it prevents injuries. A brake shoe 16 is fixed to the tip of the cylinder 17 and applies a brake to the entire length of the alignment roll 8.

To explain each of the above members in a series of operations, the conveyor claws of the intake conveyor 5 take in the longest village 3 one by one,
It is delivered to the alignment conveyor 6. In this process, the end surface correction conveyor 7 laterally moves the uneven end surfaces of the long materials 3 one by one toward the other end in accordance with the material advancing speed. At this time, the long material 3 is on the alignment roll 8, and each long material is on the divided rolls of the alignment roll 8 and moves laterally. Since steel pipes are usually formed into a hexagonal shape, the long materials 3 are collected in groups of the first and second stages at the bottom of the hexagon and fed into the forming frame. Therefore, the steel pipes in the intake conveyor 5 and the alignment conveyor 6 must be stopped after each group has been converged. Since this stop occurs during the end face correction, due to the inertia of the lateral movement of the long material 3, the divided rolls of the alignment roll 8 are free for the reason mentioned above, so they move due to inertia and the pipe ends are not aligned, and the alignment occurs at the same time as the stop. The roll 8 is braked by pressing the brake shoe 16 at the tip of the cylinder 7. Next, the second pipe end correction will be explained based on FIG. 6, but in this case, as mentioned above, the correction amount is approximately 2
It is within the ratio.

Reference numeral 1 denotes a bearing for the guide rod 20 which is attached to and supported by a frame on the foundation, and 24 is a holding plate provided on the front surface of the holding plate 19 for holding down the long material 3 from above and correcting lifting of the longest material 3. , the holding plate 24 is held by a support 22 via a cylinder 23. In FIG. 6, when the largest material 3 arrives at each stage, the cylinder 18 pushes the push plate 19
The final pipe end alignment is performed by advancing the pipe, but unlike the conventional method, a stopper (Fig. 1) is not required, and the forming and collecting process of the long material 3 can be fully automated, preventing noise and The effect of significantly shortening the binding time is significant.
