Abstract

PURPOSE:To enable a rolled steel material of squared section to be revolved around almost its axial core serving as the center, by providing an almost L-shaped receiving member, whose two receiving sides form an angle of about 90 deg., so as to perform a turning motion on a lifting shaft. CONSTITUTION:A squared sectional material 7, supported onto a conveying surface 8 of a roller conveyer, is supported onto a receiving side 6a and straight floated by coaxially actuating a lifting cylinder 1 and a revolving cylinder 13 and lifting a receiving member. Thereafter the receiving member 6 is revolved along a guide hole so as to support the squared sectional material 7 onto a receiving side 6b by stopping the lifting cylinder 1 while continuously actuating the revolving cylinder 13. And the squared sectional material 7 can be returned onto the conveying surface 8 of the roller conveyer in a condition that the material 7 is revolved in a 90 deg. angle by actuating the lifting cylinder 1 and the revolving cylinder 13 to be simultaneously contracted.

This device has the drawback that when the steel material is turned, the position of the steel material shifts significantly in the width direction, and also has the drawback of damaging the R4 material and making a lot of noise. Additionally, a device has been used in the past in which the steel material is suspended over a chain temporarily installed in its width direction, and the chain lifts the steel material from the conveyor and rotates it.In this case, the noise is low and there is little lateral slippage, but scratches are eliminated. It was impossible to do so, and there was no certainty in its operation.

The distance should be approximately half the width of the rectangular material from the sides.

2 is a lifting shaft connected to the end of the operating shaft with a pin 3;
4 is a bearing that vertically guides the lifting shaft 2; 5 is a support fixed to the upper end of the lifting shaft 2; In the abbreviated-shaped receiving portion 6, the internal angle α formed by both receiving portions 6a and 6b is 90 degrees. Reference numeral 7 indicates a meat material with a side length of W, 8 indicates a conveyance surface of a roller conveyor that supports the meat material, and 9 indicates a supporting member 6.
The guide hole is formed in an arcuate shape, and the guide hole is formed so that its center of curvature 0 is located at a distance of 1/2 W (that is, half the width dimension of the meat material 7) from both receiving portions fla and fib. do. Further, the outer periphery +t10 of the receiving member 6 is formed concentrically with the guide hole 9. Then, the guide rollers u, u attached to the support 5t are loosely fitted into the guide hole 9, and the guide roller n is brought into sliding contact with the outer green 10, so that the support member 6 can freely pivot around the point 0. I will support you as much as possible. 1
Reference numeral 3 denotes a rotating cylinder that is swingably supported by a horizontal shaft 14 on one side of the lifting cylinder 1, and the operating shaft end of the cylinder is pivotally connected to one end of the support member 6 by a pin.

It is sufficient to guide the meat material 7 so that it can rotate about a point that is approximately half the width W of the meat material 7 away from the branch. still,
The center of rotation of the support member may be slightly shifted depending on the tolerance of lateral displacement of the material to be turned, so the center of rotation of the support member and the distance from both support members should be centered around half the width of the meat material. As long as it is within the range of about ±3096.
