DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a width cutting device for cutting one or both sides of a flat deck plate in the width direction.

[0002]

2. Description of the Related Art As shown in FIG. 4, which is an explanatory view of a width cutting process, a flat deck plate (hereinafter also referred to as a product) 10 having one side flat and a plurality of ribs provided on the other side.
Has the advantage of saving the amount of cast concrete compared to a deck plate with valley grooves, and is used as a formwork for concrete floors. When used as a mold, it is upside down from the illustration, and the flat surface is the upper surface. Meanwhile, depending on the beam span in the width direction of the deck plate on which the deck plates are laid, there may be a surplus in the width dimension at the end in the width direction of the deck plate. In this case, there is a case where a so-called width cutting process for cutting one side or both sides in the width direction of the deck plate to reduce the product width is performed (see A, B, C, and D in FIG. 4). Conventionally, the width cutting process is performed by passing a flat deck plate between a pair of upper and lower cutter rolls. However, the conventional width cutting device has only one pair of cutter rolls, and this cutter roll is manually operated. The mechanism was such that the cutter roll was moved in the product width direction by manually turning the handle to change the width cutting position. In addition, the conventional width cutting device is not linearly arranged on the roll forming machine (that is, it is not arranged on the extension of the forming direction), and is installed as a separate line once taken out from the run-out table in the lateral direction. It had been.

[0003]

As described above, the conventional width cutting device has only one set of cutter rolls and is manually adjusted in the width direction, so that the width cutting position can be quickly changed. Cannot be installed linearly downstream of the molding machine due to processing capacity limitations.
This method is performed on a separate line after being taken out in the horizontal direction. However, in this method, the efficiency of the width cutting process is low and the cost of the width cutting process is high. There's a problem. By the way, in order to efficiently lay out deck plates between beams at a construction site, it is sometimes required that the stacking order of the packing of the deck plates carried into the site be laid out and be in the same order. In this case, it is natural that deck plates with different width cutting positions are included in one package. However, a conventional width cutting device with a slow processing speed only copes with a case where products with a constant width cutting position are continuous. Therefore, it is not possible to immediately stack products that are continuously sent in the order of laying at the construction site as described above.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks, and can quickly respond to a change in the width cutting position, can be arranged on the extension of the roll forming machine in the forming direction, and can save equipment space. It is an object of the present invention to provide a flat deck plate width cutting device which does not occupy and can be easily stacked in the order of laying deck plates at a construction site.

[0005]

Means for Solving the Problems The present invention for solving the above problems is arranged on a roll forming machine extending in the forming direction, and is formed by the roll forming machine, cut into fixed lengths, and sent. > a wide cutting device for cutting the widthwise one side or both sides of the rat deck plate, provided one pair each product widthwise direction right and left pair of upper and lower cutter roller movable in the product width direction, feed Individual hula coming

And a scrap discharging device for discharging the cut right or left scrap.

[0006]

In the above construction, the flat deck plate (product) formed by the roll forming machine is cut into a fixed size, and then sent straight as it is to the width cutting device. In the width cutting device, one or both sides in the product width direction are cut by the left and right cutter rolls. In this case, the cutter roll is automatically moved by the cutter roll moving device in accordance with the width cutting position of the product to be cut to perform a predetermined width cutting process. Scrap generated by the width cutting is discharged by a scrap discharge device on the downstream side. Since the cutter rolls are provided on the left and right sides and are quickly moved by the cutter roll moving device, the width cutting position can be arbitrarily changed. Therefore, it is possible to perform width cutting in the order of stacking for product bundling and to send out the products, so that products having different width cutting positions can be stacked in an arbitrary order.

When the center rib 10a is guided by the guide member 46, it passes in a state where it is correctly positioned in the width direction, and the upper and lower cutter rolls 30 and 31 can correctly cut a predetermined position of this product.

The flat deck plate 1 shown in FIG.
0 is a key-shaped edge 10b bent at one end at a right angle
(See FIG. 4).
In the case of A type width cut product that cuts very close to 0b,
Since the scrap does not proceed linearly but proceeds with an irregular twist, it is very difficult to discharge the scrap smoothly. Therefore, the edge guide member 86 as shown in FIGS. 5, 6, and 7 may be disposed downstream of the cutter rolls 30, 31. The edge guide member 86 has a cross section having a substantially key-shaped cylindrical hollow portion 86a, and extends the front end of the lower plate 86b to extend the upper and lower cutter rolls 3.
It is arranged so as to be close to the meshing position K of 0,31.
FIG. 7 shows an arrangement in the case of the A-type width-cut product. The edge guide member 86 has a key-shaped cylindrical hollow portion 86 as viewed from the front.

According to the edge guide member 86, when cutting only the vicinity of the key-shaped edge 10b of the product 10, even if the scrap is twisted, the scrap passes through the key-shaped cylindrical hollow portion 86a. ， Can be smoothly guided and discharged. Of course, it is also effective as a guide for scraps in the case of B-type and C-type width cut products.

The deck plate to which the width cutting device of the present invention is applied is not limited to the flat deck plate having the cross-sectional shape shown in FIG. If the deck plate has a flat surface on one side, the shape of the rib itself is arbitrary.

The guide mechanism for guiding the passing product is not limited to the mechanism for guiding only the central rib 10a, but may be a mechanism for arranging a guide member between the ribs or another mechanism. Can be.

Although the tilt table for dropping the scrap has a rotatable structure in the embodiment, a fixedly tilted table may be used if the progress of the scrap until dropping is not hindered. Conceivable. In addition, the scrap discharging device of the embodiment includes a first discharging conveyor 65.
And an upwardly inclined second discharge conveyor 66 adjacent thereto
However, depending on the height position (discharge height position) of the scrap bucket 76, only the first discharge conveyor 65 may be used.
