この考案は、鉄板等の大板を反転する装置に関
する。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device for reversing large plates such as iron plates.
この種の従来の反転装置として、特開昭50−

As a conventional reversing device of this type,
As described in Japanese Patent No. 14227, a horizontal rotating shaft is provided with a plurality of radial arms protruding from the same plane at predetermined intervals along the axial direction of the rotating shaft, and each arm is connected by a span. There is one in which a pair of integrated large plate mounting frames are mounted so as to be rotatable in opposite directions from a substantially vertical direction by a drive machine.

行せず大きな音が生じ、作業環境の悪化を招いて
いる。 However, in this conventional example, a protrusion is provided on the rotation axis side of the frame, and when the frame is reversed, the side edge of the large plate is brought into contact with this protrusion, thereby fixing the movement of the large plate toward the rotation axis in the radial direction of the reversal. are doing. For this reason, when a large plate is transferred from one frame to another (during delivery), the large plate slides on the protrusion, and due to the sliding resistance, the large plate does not transfer smoothly and becomes large. This creates noise and causes a deterioration of the working environment.
このため、従来では、特公昭47−51631号公報
に示されるように、大板の回転中心部に、その大
板側縁の回転軌道跡に沿う周面の回転輪を設ける
技術がある。 For this reason, conventionally, as shown in Japanese Patent Publication No. 47-51631, there is a technique in which a rotating ring is provided at the center of rotation of a large plate, the circumferential surface of which follows the rotation trajectory traces of the side edges of the large plate.
しかしながら、この技術においては、両アーム

て受取り側にかなり倒伏させなければならない。
この受渡し側アームの大角度の回転は、作業時間
が長くなるうえに、駆動機が油圧シリンダの場
合、そのストロークが長くなつてスペース的に問
題が生じる。 However, in this technology, when the large plate is delivered when both arms are upright, the side edge of the large plate comes into contact with the rotating wheel and is pushed toward the delivery side (see frame 3 in the embodiment), causing the rotating wheel to collapse the large plate. If the large plate is rotated in the opposite direction, the large plate may slide toward the delivery side and may not be turned over smoothly. Therefore, both arms are
They must be lowered together to a considerable angle. That is, the delivery side arm must go beyond its upright position and lie down considerably on the receiving side.
This large-angle rotation of the delivery-side arm not only increases the working time, but also causes problems in terms of space because, if the drive device is a hydraulic cylinder, its stroke becomes long.
また、アームには、その長さ方向に大板を円滑
に移動させる手段を設けて、大板側縁を回転輪に
円滑に当接させることが好ましい。 Further, it is preferable that the arm is provided with a means for smoothly moving the large plate in the length direction thereof, so that the side edge of the large plate is brought into smooth contact with the rotating ring.
この考案は、以上の点に留意し、大板がスムー

In order to solve the above problems, in this invention, in the above-mentioned large plate reversing device, a rotating ring on the circumferential surface along the rotation locus of the side edge of the large plate is attached to the rotation center of the large plate, and the rotating ring is attached to the rotation axis of the large plate. A plurality of arms are provided at required intervals in the axial direction of the main arm, and an auxiliary arm having the same length is attached to the upper surface of the main arm rotated by the drive machine via a spring so as to be able to move toward and away from the main arm in the vertical direction. The auxiliary arm is provided with rollers at required intervals in the longitudinal direction for moving the large plate placed thereon, and the outer periphery of each rotating ring is provided at the base end of the auxiliary arm of the receiving frame. A vertical extrusion portion protruding inward from the surface is provided, and the roller side surface of the extrusion portion is on the inside approaching the outer peripheral surface level of the rotating ring when the auxiliary arm is parallel to the main arm, The upper end is located higher than the upper end of the roller, and the protrusion length of the extrusion portion is such that when the auxiliary arm is inclined downwardly outward in the longitudinal direction with respect to the main arm, the upper end protrudes from the outer circumferential surface of the rotating shaft.

As shown by the chain lines, both frames 3, 3' are erected and come into contact with each other with the large plate A interposed therebetween when they are in a substantially vertical state. The frame 3' may also be erected at the front. If you turn slightly clockwise from this state, 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 due to the presence of the spring 7, the auxiliary arms 4a, 4a of both frames 3, 3' 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. Further, the extrusion portion 11 prevents the side edge of the large plate A from moving toward the frame 3 side. Therefore, the delivery is carried out smoothly and no noise is generated.
