Abstract

PURPOSE:To prevent a generation of abrasion and to maintain a surface quality of a product by installing a skew roller between a freely ascending and descending roller and a lifting skid equipped on a line table to reduce a rubbing at displacing a material. CONSTITUTION:When the material W is reached on a prescribed position, the roller 3 is descended from the upper surface to the under side of the skew roller 12. Thus, the material W on the roller 3 is moved on the skew roller 12. Then, after sending off the material, the roller 3 is ascended to prepare advancing a next material. The material W on the skew roller 12 is moved to another end by a rotation of the skew roller 12, and scooped up by the lifting skid 13 at the time as the rotation of the skew roller 12 is stopped. Then, the material W is rotated on the skid to move on a accumulating skid. In this way, the material is moved without getting an abrasion on the material.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for stacking elongated materials such as steel materials in an aligned state.

(Prior art) In a long steel rolling line, long products that have been hot-rolled or products that have been cut with a hot saw are kept in an aligned state in order to be sent to the next process such as cooling, cutting, and finishing. In many cases, a plurality of sheets are stacked, and a device shown in FIG. 3 is generally used as an alignment and stacking device for this purpose.

In the figure, 31 is a run-in table in which a plurality of motor-driven rollers 32 are arranged along the material travel path, and 33 is a skew row 534 on the side of this run-in table 31.
The material (long steel) W conveyed on the run-in table 31 is a skew table with a plurality of
is pushed sideways and transferred onto the skew table 33. The materials W conveyed diagonally forward on this skew table 33 advance to a position where their tips hit the stopper 36 and are aligned, and after a plurality of materials W are accumulated, the stopper 36 is lowered or raised. It is sent to the next process by a run-out table 37 consisting of a row of rollers. 38
is a guide roller that guides the side surface of the material W on the end side.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional material alignment and accumulation device 30,
First, when the material is transferred from the run-in table 31 to the skew table 33, scratches occur because the material slides on the rollers 32, and in the case of round materials, the material is transferred on the skew table 33 due to extrusion by the pusher 35. Accidents caused by collisions with pre-assembled materials were likely to occur. Furthermore, since the materials W are aligned and stacked on the skew table 33, the front matter is held at a stopped position by the stopper 36 on the rotating skew roller 34 until the final material among the plurality of materials is aligned. A large amount of scratches occur due to the slip with 34.

Furthermore, since the materials are accumulated on the skew table 33, the direction of conveyance after accumulation is limited to one direction.

This invention solves the above-mentioned conventional problems, and aims to provide a material alignment and stacking device in which the occurrence of material scratches is small and the direction of conveyance after stacking can be freely selected.

(Means for Solving the Problems) However, the material alignment and accumulation device of the present invention includes a run-in table in which a roller for supporting the material can be raised and lowered vertically, and a skewed roller located directly below the material travel path of the run-in table. a skew table on which one end of the roller is located and equipped with a variable speed drive device for the skew roller; a plurality of accumulation skids arranged on the side of the other end of the skew roller; and a vicinity of the other end of the skew roller. This material alignment and accumulation device is provided with an elevating and lowering skid which is disposed so as to be movable up and down, and whose sloping upper surface reaches above the other end when reaching the upper limit.

(Function) In the material alignment and accumulation device of the present invention, the rollers of the run-in table transport the material in the upper limit state, and transfer the material onto one end of the skew roller in the downward stroke. Skew 1 - The speed of the roller is changed by a variable speed drive, and the material arriving near the other end of the skew roller is decelerated and skimmed onto an ascending lifting skid while being conveyed at zero speed (stopped) or at a low speed. The materials are transferred or slid along the sloped upper surface of the lifting skid, and are aligned and collected on the collecting skid. Since the material is accumulated on a stationary accumulation skid, it can be carried out in a desired direction by roller drive or lateral carrier transfer and sent to the next stage.

(Example) An example of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is a run-in table, and a roller 3 for supporting material driven by a motor 2 is tiltable around a support shaft 5 supported by a bracket 4 as shown in FIG. 2, and is not shown. An eccentric disc cam 7 is fixed to a drive shaft 6 which is rotated at low speed by a motor, and a link 8b is fixed to a ring 8a which is rotatably fitted to the cam.
As shown by arrow X, it is driven up and down (swinging). A free roller 9 guides the material W on the material traveling path 10, and is rotatably supported around a vertical axis. Reference numeral 11 denotes a skew table in which one end 12a of a plurality of skew rollers 12 is located directly below the material running path 10, and a motor (not shown) for driving each skew roller 12 is a known motor such as an inverter device. It is designed to be driven at variable speed by a variable speed drive (control) device. Reference numeral 13 denotes an elevating skid provided near the other end 12b of the skew roller 12, which is tiltable around a support shaft 15 supported by a bracket 14 as shown in FIG. 2, and is rotated at low speed by a motor (not shown). An eccentric disk cam 17 fixed to a driven drive shaft 16 moves up and down as shown by arrow Y (Jl movement) via a link 18b fixed to a ring 18a rotatably fitted to the cam.
It is becoming more and more popular. A plurality of stacking skids 19 are arranged along the material alignment direction parallel to the material running path 10 on the side of the skew roller 12, and are shaped like an abutment fixed on a foundation.

In order to align and accumulate materials W made of round steel using the material alignment and accumulation device 20 having the above configuration, first, the run-in table 1 transports the materials W along the material travel path 10 in the direction of arrow Z. The roller 3 is swinging at a low speed in the direction shown by the arrow The material W is one end 1 of the skew roller 12
It will be transferred to 2a. After this transfer, the roller 3 reaches the lowest point and then reverses and rises to prepare for the next material to enter. On the other hand, the material W transferred onto the skew table 33 is conveyed diagonally forward by the skew roller 12 as shown by the arrow R, and as it reaches the other end 12b of the skew roller 12, the skew roller 12 is decelerated by a variable speed drive device. is,
It is in a stopped state or a very low speed driving state, and in this state, it is scooped up by the lifting skid 13 which is rising. The skew row 512 is accelerated for conveying the next material,
On the other hand, as the lifting skid 13 continues to rise, its upper surface 13a becomes an inclined surface with the accumulation skid 19 side facing down, as shown by the chain line, and the material W is transferred on this upper surface 13a and transferred onto the accumulation skid 19. Ru. By repeating the above process multiple times, a plurality of materials W are aligned and stacked on the stacking skid 19, so these materials are moved to the side as shown by arrow S by a carrier A7 (not shown) or run out (not shown). All you have to do is raise the rollers on the table and carry it out in the longitudinal direction. Note that the accumulation skid 19 may be constituted by an O-roller that rotates around a horizontal axis, and this roller may be rotationally driven only during unloading.

In this way, when the material is transferred from the run-in table 1 to the skew table 11 and from the skew table 11 to the accumulation skid, the material hardly slides and is even more stationary. Accumulation skid 1
Since they are stacked on the skid 9, they do not slide on the skid while waiting for stacking. In addition, since the skew roller 34 is driven at a variable speed, it is possible to perform smooth transfer with little slip when transferring from the run-in table 1, and when transferring to the accumulation skid 19 by the elevating skid 13, collision of materials with each other due to deceleration is possible. It is possible to prevent this.

The present invention is not limited to the above-mentioned embodiment. For example, instead of the above-mentioned configuration in which the rollers 3 and the elevating skids 13 of the run-in table 1 move up and down by tilting, they are not tilted and are guided in the vertical direction to move up and down. It may also be configured to move up and down.

Although the case where the material is round steel has been described above, the present invention can be applied to an arrangement and accumulation device for square steel and other materials having various cross-sectional shapes. Note that in the case of a cross-sectional shape other than circular, the material will slide on the lifting skid 13 for a short time due to transfer, so it is preferable that the upper surface 13a of the lifting skid 13 be made of a smooth material such as a stainless steel plate. Furthermore, it is particularly preferable to arrange a large number of free rollers in parallel on the upper surface to eliminate sliding.

(Effects of the Invention) As explained above, according to the present invention, the material is transferred between each component device by the rollers that move up and down or the skid, and is aligned and accumulated on the accumulating skid in a stationary state. This greatly reduces the number of scratches caused by motion and greatly contributes to improving the surface quality of the material. Further, since the materials are transferred to the accumulation skid after being brought to a stop or deceleration state by a skew roller driven at a variable speed, collision accidents of materials can be prevented.
