Abstract

PURPOSE:To smoothly turn round a large-sized plate and to prevent worsening a working environment caused by noise, by providing plural rotating wheels of which a rotating shaft is abutted on a side end of the large-sized plate in the axial direction to be rotated with the rotation of the large-sized plate. CONSTITUTION:One frame 3 is set in a horizontal state, the large-sized plate A is mounted on the frame by a crane, conveyer, etc. Then, both frames 3, 3 are erected by a cylinder 10, when these go to nearly vertical states, abutted interposing the large-sized plate A. When the abutted frame is slightly rotated rightward, the large-sized plate A is moved to the rightward frame 3' by its dead weight, after that rotates along with the frame 3' to be a reversed horizontal state. At the time of delivering this, a revolving shaft 8 is rotated with moving the large-sized plate A, and due to the existence of a spring 7, the auxiliary arms 4a, 4b of both frames 3, 3 move corresponding to the thickness of the large-sized plate A. Thus without generating a clearance between the large-sized plate A, the delivering is smoothly performed without generating the noise.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an apparatus for reversing large plates such as iron plates.

[Conventional technology and its problems]

This type of conventional reversing device has a plurality of radial arms protruding from two horizontal rotating shafts at predetermined intervals along the axial direction on the same plane, and each arm is connected by a span. The integrated large plate mounting frame is moved by a drive machine.
They are mounted so that they can rotate in opposite directions from a substantially vertical direction.

However, in this conventional example, when the large board is transferred from one frame to the other frame (during delivery), the large board slides, causing a loud noise, resulting in a deterioration of the work environment.

(Object of the Invention) The present invention takes the above points into consideration and aims to provide a reversing device that can smoothly transfer a large plate.

[Means to achieve the purpose]

In order to achieve the above object, the present invention attaches both of the above-mentioned frames to a single rotating shaft, and furthermore, attaches the rotating shafts on which the side edges of the large plates come into contact at required intervals in the axial direction. We set up multiple locations.

[Effect]

The reversing device configured in this way reverses a large board in the same manner as in the past, but when rotating the large board by placing it on a frame,
The side edge of the large plate comes into contact with the rotating ring, and as the large plate rotates, the rotating ring also rotates, so the large plate rotates smoothly, and the large plate can be transferred between both frames smoothly due to the rotation of the rotating ring. It is done.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a horizontal rotating shaft 1 is provided in the focus P via a bearing stand 2, and a frame 3.3 for the large plate AR1 in the radial direction is attached to the rotating shaft 1. ' are mounted so as to be rotatable in opposite directions from a substantially vertical direction by a hydraulic cylinder 10. Instead of the hydraulic cylinder 10, various driving devices such as a screw jack can be used.

The frame 3.3' has a plurality of arms 4 in a span 5.
The arm 4 is composed of an auxiliary arm 4a having a roller 6 and a main arm 4b supporting the auxiliary arm 4a via a spring 7 so as to be movable up and down. Therefore, when the large plate A is placed on the frame 3.3', even if the large plate A has undulations, each auxiliary arm 4
Due to the movement of a, the undulation is absorbed and the frame 3.
3', a large plate A is perfectly supported. The springs 7 are provided in pairs in the width direction of the main frame 4b.

As shown in FIGS. 2 and 3, the rotating shaft 1 is provided with rotating shafts 8 at required intervals in the axial direction, and as shown in FIG. 4, a large plate A is mounted on the auxiliary arm 4a. When the frame 3 rotates upward when placed, the large plate A moves toward the rotating shaft 1 side by the rollers 6 and comes into contact with the rotating ring 8. From then on, the rotating shaft 8 rotates as shown by the chain line in the figure. Guide the side edge of large plate A. An elastic body 9 made of synthetic resin or the like is provided at the base end of the auxiliary arm 4a.

The embodiment is configured as described above, and its operation will be explained next.

Now, as shown by the solid line in FIG. 1, when one frame 3 is in a horizontal state, when a large plate A such as a steel plate is placed on the frame 3 by a crane, conveyor, etc., the cylinder 1
0, both frames 3 and 3' are erected and come into contact with each other with the large plate A interposed therebetween, as shown by the chain lines in Figure 1 (when both frames 3 and 3' are in an almost vertical state. Frame 3' has been erected in advance. It is also good. From this state, if you turn a little to the right, you will see a large plate A.
is transferred to the right frame 3' by its own weight, and thereafter rotates together with the frame 3' to be in an inverted horizontal state. During this delivery, the rotating wheel 8 rotates as the large plate A moves, and the presence of the spring 7 causes the auxiliary arms 4a, 4b of both frames 3.3' to move in accordance with the thickness of the large plate A. Therefore, there is no gap between the large plate A and both auxiliary arms 4a, 4a, and the transfer is carried out smoothly and no noise is generated.

Note that the cylinders 10 on the same side of the rotating shaft 1 must be synchronized.

〔Effect of the invention〕

The present invention is constructed as described above, and the large plate is guided by the rotary wheel, so that the large plate is smoothly reversed, and the work environment is not deteriorated due to noise or the like.
