Description

[Detailed description of the invention] The present invention is a cropping process that is added to remove cut scraps from the product pass line in a cold shearing machine that cuts a long wire rod product after the rolling process to a fixed size. Regarding equipment.

Traditionally, most of the cropping process has been done manually, which is inefficient and dangerous. Mechanical crop processing devices include a side pusher method that removes crops to the side, but when a hole blade is used as the lower shear blade to cut multiple products at the same time, products stuck in the holes may be removed. Cannot be used because crop cannot be pushed sideways.

Also, when installing a forward and backward crop processing device, due to the equipment configuration of this type of cold shear, the crop processing device must be placed between the shear blade and the product holding roller, otherwise the crop processing device cannot move forward. There is a problem that the presser roller sometimes gets in the way. Due to this conflict, the presser roller has to be placed in front of the crop processing device, that is, in a direction away from the blade, and as a result, poor presser movement causes poor cutting and bending due to wobbling during cutting. Furthermore, since the transportable length cannot be shortened, the crop length becomes long, resulting in a decrease in yield and an increase in the size of incidental equipment such as crop shoots and bags. Additionally, the structures tend to be large, complex, and expensive.

The cropping device of the present invention has been developed to solve the above-mentioned problems of the conventional cropping technology, and its configuration is such that the front roller table is located at the maximum position relative to the shearing blade in a sizing shearing machine for wire rod-shaped products. The combination of the tip roller and the presser roller placed above it is used as a pinch roller for holding and transferring the product, and is placed close to the shearing blade so that it can be lowered from the product pass line, and the crop pincher can be raised and lowered to the height of the product pass line. It is characterized in that it is provided so as to be able to move back and forth in the front and rear directions beyond the position of the lowered roller set.

That is, in the present invention, a presser roller is used, and by being placed as close as possible to the shearing blade, it plays the role of holding the product during shearing. Therefore, there is no need to separately provide a product presser, and by omitting it, the distance between the shearing blade and the presser roller can be shortened. Further, the presser roller works in combination with the most advanced roller of the front roller table to move the product forward and backward. The presser roller thus serves two active functions. Then, passively, this roller set is lowered and retracted from the product pass line height.

In this state, the crop picker can freely move forward and backward in the direction of the product pass line. Furthermore, since the crop shear can be placed far from the shearing blade position, the roller set can be placed close to it. In this way, the configuration of the device of the present invention can only be realized through the mutual relationship of the four roles of the presser roller.

Hereinafter, the present invention will be explained in detail with reference to specific embodiments shown in the accompanying drawings. FIG. 1 is a side view showing related parts of a shearing machine and a crop processing apparatus according to an embodiment of the present invention, and FIG. 2 is an enlarged side view of the crop processing apparatus.

In this embodiment, a plurality of long wire rod-shaped products are lined up and placed on the front roller table 2 of the shearing machine 1, conveyed along the pass line P to the left in FIG. 1, and guided to the entrance guide 3. It passes between the upper blade 4 and lower blade 5 of the shearing machine 1, and the rear roller table 6
conveyed above. Then, it stops when it hits a sizing machine (not shown), and the upper blade 4 descends toward the lower blade 5, thereby cutting by a down cut method. The rear roller table 6 carries out the material to be cut to size in the direction of the pass line.

In the present invention, the most advanced roller 2a of the front roller table 2 is placed as close as possible to the shearing blades 4 and 5, that is, near the entrance guide 3, and is operated by an air cylinder 10 connected to support arms 9 on both sides. It is equipped to be tiltable downward about the axis of the next roller 2b.

A presser roller 11 disposed above and combined with the most extreme roller 2a is supported between the ends of support levers 12 on both sides, and the lever 11 is centered around the shaft 15 of the crop processing device 14 fixed to the shear body 13. Air cylinder 16 connected to the other end
It is equipped so that it can be tilted downward.

The set of the presser roller 11 and the leading edge roller 2a is configured as a pinch roll that pinches the product at the pass line height between them and is rotatably driven to transfer the product in the front and back direction of the pass line. By tilting downward, the rollers 11 and 2a are lowered and retracted from the product pass line height as shown by chain lines in FIG.

The crop pusher 17 is attached to the tip of the crop pusher 18 at an intermediate position between the support levers 12 on both sides of the presser roller. Crop push shear 1
8 is guided by a horizontal guide 19 of the frame 14 and supported by an air cylinder 20 connected thereto so as to be movable forward and backward in the pass line direction. The crop pusher 17 is rotatably supported by a shaft 21 at the tip of the crop pusher 18, and is moved by an actuator 22 between an upwardly retracted position and a downwardly operating position. In the normal state, it is retracted upward and is located farther from the shearing blades 4 and 5 than the presser roller 11, and when pushing out the crop, it descends to the operating position and is moved in the pass line direction by the crop pusher 18. The crop is now being pushed forward.

The operation of the crop processing apparatus of the present invention having the above structure will be explained with reference to the related operation diagram of the crop kicker 17, the presser roller 11, and the most extreme roller 2a of the front roller table in FIG.

Figure 3 A shows product A on the front roller table 2.
This shows a state in which the product is sent in the pass line direction by rollers 11 and 2a, and the product is pressed by the presser roller 11 to perform cutting of the leading end and successive cutting of the length-sized material.

FIG. 3B shows a case where the crop length is short and comes off from the front roller table 2 due to the rear end cropping process or the like. In this case, the presser roller 11 and the most extreme roller 2a are lowered, and the lowered crop kicker 17 is advanced to push out the crop A'. After extrusion, the crop pusher 18 is retracted into position.

FIG. 3C shows a case where the rear end is cropped and the crop length is long and the rear end is on the front roller table. In this case, as shown in FIG. 3D, the pinch roller set 11, 2a is driven to advance the crop A' to the point where it can be advanced, cut off its tip, and then cut off the remaining crop A'' as shown in FIG. As shown in E, it is extruded in the same manner as in FIG. 3B.

The device of the present invention is also capable of dispensing the crop to the front side when the length of the crop is long, and as shown in FIG. into another shoot bag (not shown) on the side. This long trailing end crop A' can be used as material for shorter short lengths.

According to the present invention having the above structure and operation, the following effects can be obtained.

(a) Since the product is pressed and cut by a presser roller close to the cutting blade, defects in the cut surface are prevented and the shape of the product is improved.

(b) The length of the waste crop is reduced.

(c) Since crop processing is performed in an orderly manner without interfering with other operations, processing capacity can be increased.

(d) The equipment is constructed in a relatively simple and intensive manner.

(e) Ancillary equipment such as chute, bag, etc. shall be installed on the rear side unless pulling back a long crop.
In addition, there is no need to increase the size.

(f) Labor-saving can be achieved due to the rational and reasonable operation method.

(g) Improved safety.
