Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is a method for folding processed strips onto a transport cart placed on the floor, which is connected to a pull-out device in a discharging section of a strip processing machine. This invention relates to a shaking-off device for shaking off layers.

[Prior Art] As a device for shaking off a strip, a horizontally swingable strip guide plate is provided below the final guide roller, and the strip guided by the final guide roller is shaken off from the lower strip. The object is passed through a guide plate, and its swinging motion causes the object to be swung into a cart placed on the floor.

[Problems to be Solved by the Invention] However, since the conventional shaking-off device merely shakes off the strip-shaped object, the joint of the strip-shaped object is placed inside the transportation trolley together with other parts. can be folded over. In this state, it is very troublesome to find a seam among a large number of folded strips.

Additionally, if the joint is to be brought out of the transport vehicle before it enters the transport vehicle, a joint monitoring personnel is required. When a monitoring staff member finds a joint, it is very inefficient to hold the joint in his hand and remove it from the transport trolley, and there is also the problem that mistakes in pulling out the joint may occur due to oversight.

[Means for solving the problem] Therefore, in order to solve the above problem, the following measures were taken.

In the shake-off device of the present invention, a pull-out device for pulling out the processed strip is installed in the outlet portion of the heat treatment machine, and a final guide roller for guiding the strip is disposed near the exit of this pull-out device. A pair of mating and opposing strip guide plates that swing horizontally are provided below the guide roller,
In the belt-shaped object shaking-off device, the belt-like object guided to the final guide roller after being sent out from the drawing device is shaken down downward through the pair of band-like object guide plates. A point detection sensor for detecting seams and marks of the strip is provided on the supply side, and at least one of the pair of strip guide plates has a two-layer structure of a fixed guide plate and a movable guide plate. The plate is supported by a shake-off device, and the movable guide plate is provided so as to be slidable downward along the fixed guide plate, and the movable guide plate moves downward as the point detection sensor detects a seam or mark on the strip. By sliding, the width of the strip to be shaken off is expanded, and the joint or mark portion can be pulled out to the outside of the strip-shaped article transporting cart.

[Function] In the shake-off device of the present invention, the processed strip is sent out from the drawer device of the outlet section of the processor. The strip is then guided by a final roller disposed near the exit of the drawing device to a pair of mating and opposing strip guide plates provided below the final roller. Since this strip guide plate is swingable in the horizontal direction, the strip passing through the strip guide plate swings along with this reciprocating motion. As a result, the strip is shaken off and folded into a strip transport trolley placed on the floor.

Furthermore, when a seam or a pre-applied mark on the strip reaches a point detection sensor provided on the strip supply side of the final roller, the point detection sensor detects the seam or mark. With this detection, the moving guide plate that constitutes the strip guide plate slides downward along the fixed guide plate. As a result, the length of the strip guide plate in the strip traveling direction increases, the width of shaking off the strip increases, and the joints and marks on the strip are automatically shaken out of the strip transportation trolley. It can be dropped.

[Example] Hereinafter, one embodiment of the present invention will be described based on the drawings.

Next, the operating state of this shake-off device 1 will be explained.

The strip-shaped material A that has been processed through steps such as heat treatment is pulled out by a bowing device H provided at the lead-out portion of the heat treatment machine. Then, it is guided to the final guide roller 12 by several rollers provided in this pull-out device H and the guide rollers 32 and 34. The strip A, which has passed through the final guide roller 2, is turned downward and enters between the fixed guide plates I8.20.

Along with this, a drive source such as a motor is operated to rotate the crank roller 2B. This rotation is transmitted to the support frame 14 by the crank arm 30, and the support frame I4
swings horizontally and in the longitudinal direction, and at the same time the fixed guide plate I8.20 swings. The strip A, which has passed through the fixed guide plates I8.20 after entering them, is shaken off by the above-mentioned rocking movement into the transport trolley C installed below these fixed guide plates I8.20. , and are folded up in a transportation trolley C.

As the strip A continues to travel, the joint N1 or mark N1 to the strip is sent out from the drawer H and reaches the point detection sensor 38, where it is detected. At the same time that the seam M or mark N1 is detected by the point detection sensor 38, the travel path MDI constant sensor 36 is activated.

The running path M measurement sensor 36 is for measuring the running distance from the position of the point detection sensor 38 of the seam M or the track Ll to the lower end of the fixed guide plate 18.20. When the measurement by the mileage measuring sensor 36 is completed, in other words, the seam M or mark M passes through the point detection sensor 38 and the fixed guide plate 18.2
When the belt reaches the lower end of 0, the air cylinder 26 is actuated by a signal from a control box (not shown), and the moving guide plate 22 or 24 slides downward at the traveling speed of the strip A and the speed between the tracks.

If the support frame 14 is tilted backward as shown in FIG. 3 at the time when the measurement by the travel distance lp setting sensor 36 is completed, a The moving guide plate 22 is moved by the air cylinder 2B. In the opposite case, the movable guide plate 24 is moved by the air cylinder 26 provided on the fixed guide plate 20. In any case, the width of shaking off the belt-shaped object will be expanded, and as a result, the part of the seam M or mark M in the belt-shaped object A will be
It can be automatically taken out to the outside.

In this embodiment, crank rollers 28 are provided on the pair of left and right support legs 12 in order to swing the support frame 14 back and forth, but this is not necessarily necessary and the final guide roller 12 may be used as a shaking-off roller, and one end of the crank arm 30 connected to the support frame 14 may be attached at a position off the center of the final guide roller 12.
