Description

[Detailed description of the invention] The present invention relates to a device for aligning the side edges of steel plates, and more specifically, for aligning the side edges of a large number of stacked steel plates having the same width with uneven side edge portions on the same vertical line. Regarding equipment.

A conventional device for aligning the side edges of a steel plate uses a flat base plate having dimensions larger than the vertical and horizontal dimensions of the steel plate;
It consists of at least two edge-setting rollers on each side that are attached to opposite side edges of both sides of the steel plate placed on the base. When aligning the side edges of the steel plates, a crane suspends a large number of stacked steel plates of the same size with uneven side edges, and the side edges of the steel plates are placed inside the upper end of the edge-aligning roller. Then, when the steel plate falls due to its own weight, the edge-setting roller rolls, causing the steel plate to fall to a position determined by the edge-setting roller. At the time of this falling, the side edges of the steel plate are aligned on the vertical line by an edge-aligning roller. However, with conventional equipment, it is difficult to use a crane to lower the steel plate so that the edge of the steel plate is placed inside the upper end of the edging roller, and the steel plate may fall off the edging roller during edging work. When doing so, there are problems such as the formation of eaves on the side edges of the steel plate. The present invention aims to solve this type of problem that occurs with previous devices for aligning the side edges of steel plates.

The purpose of this invention is to not only quickly and easily place multiple steel plates with irregular side edges that are lowered using a crane into a predetermined position, but also to place the steel plates on the same vertical line without damaging the side edges of the steel plates. The object of the present invention is to obtain a device for aligning side edges.

According to the present invention, a pair of groove-shaped frames 2 and 3 placed under the lowermost deck in the width direction of the steel plate and separated by a predetermined distance L in the longitudinal direction of the steel plate, and one side edge of the steel plate to be processed are provided. fixed bearings 4A, 4B fixed to the ends of each frame adjacent to the frame, and bearings 5A, 5B mounted on respective carts 6A, 6B reciprocatably mounted on each frame. At least two pairs of L-shaped alignment arms 7A, 7B, 7A', which are attached so as to rotate within a vertical plane in the width direction of the steel plate.
7B', and each alignment arm has an alignment completion position () where the L-shaped first leg 21 is upright, the second leg 22 is horizontal and extends below the steel plate, and a position where the first leg 21 is aligned with the vertical line. and a standby position ( ) in which it is tilted by an angle α to the side opposite to the steel plate, and is attached between the bearing and the first leg to maintain the first leg in the standby position at all times. A device for aligning the side edges of a steel plate is obtained, which is characterized by being equipped with a spring 11.

Now, an embodiment of the apparatus of the present invention will be described below with reference to the accompanying drawings.

It is pressed against the horizontal flange 2f of No. 2 from below, and locks the cart 6 to the groove-shaped pedestal 2.

In use, as shown in Figure 6a, the four alignment arms 7A, 7B, 7A', 7B' are placed in the standby position (), and the stacked steel plates W are lowered onto the top of these four alignment arms using a crane. Using the setting arm 13, the steel plate W is placed between these four alignment arms 7A, 7B, 7A', 7 with the side edge portion of the steel plate substantially aligned with the L-shaped corner 24 of the alignment arm.
When loading onto B', the lowest steel plate of the steel plates W comes into contact with the roller 20, and as these alignment arms rotate to the alignment arm completion position shown in Fig. 6b, the first leg of each alignment arm The lined surface of 21 laterally presses against the side edges of the steel plates to correct irregularities in the side edges of the multiple steel plates.

As described above, according to the present invention, each alignment arm is placed in a standby position () open to the steel material being lowered from above, so if the setting arm 13 is used, particularly careful alignment is possible. Loading of steel plates can be done quickly and easily without any need. Further, since the first leg 21 of each alignment arm rotates gradually in a direction that reduces the angle α, it does not damage the side edge of the steel plate.

At this time, the lowermost steel plate first comes into contact with the roller 20 provided at the tip of the second leg 22, so that the rotation of each alignment arm is smooth and the surface of the lowermost steel plate is damaged during this rotation. do not.
