Abstract

PURPOSE:To improve the shape of cut plates and to feed and stack smoothly said plates to and by a piler with the decreased generation of the defective plates by installing a tension controller such as a bridle roll on the upstream side of a shearing machine adjacently thereto. CONSTITUTION:A tension controller 20 such as a bridle roll is installed on the upstream side of a shearing machine 9' adjacently thereto and further a leveler 19 is installed on the upstream side thereof. The flatness of a steel strip prior to shearing is therefore improved and the shape of the cut plate after shearing is improved. The cut plate discharged from the machine 9 is easily transferred on a belt conveyor when said plate arrives at an electromagnetic roll. The shearing line is thus smoothly and continuously operated and production efficiency is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a 99-cut line VC of a copper strip, and more specifically to a shearing line that sequentially shears and stacks cut plates of a predetermined size from a thin plate unwound from a steel strip carp/L. .

A shearing line for copper strips is usually equipped with a plurality of pilers in which a large number of cut plates are neatly arranged to undergo VC shearing one after another. The cut boards that have been sheared 1' are transported to a piler by a belt conveyor and stacked, but during transportation, cut boards with defective shapes are separated from accepted products as rejected products. Both are then transported separately to a piler and stacked on top of each other. However, in the previous example, the shape of the cut plate after shearing was unexpectedly bad, resulting in not only defective products, but also problems with the upper and lower electrical connections.
Collision occurs when transferring from the straight roll to the belt conveyor, and centering failure occurs at the side guides of the laminated section, causing line speed inhibition. The present invention aims to solve these problems occurring with conventional rope shear lines.

The purpose of the present invention is to not only improve the shape of the cut plate taken out after shearing and reduce the occurrence of defective products, but also to prevent the cut plate from colliding during transportation, causing no tarnishing defects, etc. The objective is to obtain a shear line for copper strips that can be smoothly fed to the piler and laminated, which is useful for improving confectionery efficiency.

According to the present invention, a tension adjustment mechanism such as a priddle roll is installed adjacent to the shearing machine on the upstream side thereof, thereby eliminating loop equipment and creating a tight line, and installing it further upstream. The shear line of the copper strip can be obtained by being equipped with a shape correction mechanism such as a leveler.

Now, an embodiment of the apparatus of the present invention will be described as follows based on the accompanying drawings.

Referring to FIG. 1, a typical conventional steel strip shear line is shown 7'. The unwinding machine 2 equipped with the coil 1 is moved from the left end π stationary to the right (lI) at a predetermined distance from the unwinding machine 2.
A side trimmer 4 and a pinch roll 5 are arranged in order at ll. Steel; jiF is pulled out from the 4-piece 2 to form the free loop 3, and then the side trimmer 4
and the pinch roll 5 to form a safety free loop 6. Side ripper 4 cuts off the ears from the steel strip, and pinch roll 5 feeds the steel strip to the right side. On the downstream side 1111 of the right free loop 6, an automatic surface flaw inspection device 7, a pinhole inspection device and a thickness gauge 8 are arranged in order, and further downstream a shearing machine 9 is installed. The belt conveyor 121/l on the downstream side 1 of the shearing machine 9 includes several pairs of electromagnetic rolls (10, 11), (10', 11') for sorting cut plates.
), (10".

11") is installed, and the accepted products and rejected products are guided to the upper or lower conveyor direction based on the signals from the inspection devices 7 and 8 and sorted.
Sorted by 0', 11'7'L,2',2'
It is sent from the Sibelt conveyor 12Vc to the piler 13, 14 and is laminated 2'. The passed product is an electromagnetic roll (10"
.

11'') [The sheets are sorted into the order of shearing 2 and then conveyed by conveyor 12 to the piler 15.16 where they are stacked. Not only does the cut plate have a poor shape, resulting in defective products, but it also does not transfer smoothly from the electromagnetic roll to the conveyor 12, making it necessary to stop the shear line and correct the defect in the cut plate. As mentioned above, this causes a decrease in speed.

FIG. 2 shows the shearing line of the present invention, and shows the shearing machine 9'
Adjacent to the pc, a tensile circumferential bale structure 20 such as a "second-rate +1 VC priddle roll" is installed, and furthermore, a shape correction mechanism such as a leveler] 9 is installed on the θ1 side. The conventional free loops 3 and 6 installed before and after the guide trimmer 4 (Fig. 1)? Abolished, volume m4
! 2 and the priddle roll 20 so that a tension of 7'L is applied to the steel strip.

The leveler 19 applies to the steel strip, and the effect of straightening the steel strip is further promoted by increasing the tension of the steel plate.

By combining the tension of the copper strip with a leveler 19 such as a priddle roll 20, which can adjust the tension of the copper strip, a high viscosity flatness according to the well-known tension level for bending and tension straightening can be obtained. It is now possible to use a tension leveler quip that can be used before shearing! Since the flatness of the # band is improved, the shape of the cut plate after shearing is also improved. Therefore, cut it out from the shore! 15. (When reaching the in-roll, the belt conveyor 12
It is possible to improve the production rate by running the shearing line smoothly and without interruption without causing problems when changing over. Since the leveler transmits the driving power of the priddle through the copper strip 2, it does not need to be driven, and the running speed of the steel strip and the circumferential speed of the rolls match well, and there is no difference between the running speed of the copper strip and the circumferential speed of the rolls. - Prevent slippage from occurring on the copper strip due to crests. Furthermore, by applying tension to the copper strip, the copper strip is no longer shaken up and down, so that the measurement accuracy of the inspection instruments 7 and 8 can be improved. Also, set free loops 3 and 6 to 1
The total length of the child's ``Nishitatamari'' breaking line has been shortened.

Another advantage of the present invention is that basic costs can be reduced and factory layout can be made more efficient.
