The invention relates to ancillary equipment of blank production and can be used for orientation of sheets before carrying out separation operations.

The purpose of the invention is to increase the reliability of the device for the orientation of sheets and the expansion of its technological capabilities.

FIG. 1 shows a device for the orientation of sheets, a plan; in fig. section aa in figure 1; Fig. 3 shows an embodiment of the device;

The sheet orientation device comprises a cutting frame 1 mounted on wheels 2 on rails 3 with the possibility of moving along the longitudinal axis from the loading position where orientation takes place to the position of thermal cutting. At the same time, one of the wheels 2 is made with two flanges covering the rail 3, and the second wheel is mounted on the rail freely, which eliminates the possibility of displacement of the frame 1 in the transverse direction when moving it with the sheet to the cutting position

A longitudinal stop 4 is located on the lower surface of the frame 1. The device also contains two carriages 5 installed by means of wheels 6 on rails 7 placed parallel to rails 3. On each carriage 5 on two supports 8 and 9 are two-arm levers 10 and 11, the lower shoulders of which are pivotally connected respectively to the body 12 of the power qi. - the linder and the rod 13 of this cylinder The longitudinal stop 4 of the frame 1 is located between the upper arms of the levers 10 and 11, the upper arm of the lever 10 is arranged with the ability to interact with the support 4, and upper arm lever 11 - with

the ability to interact with the side with the ability to interact with the side surface of the frame 1 and the longitudinal edge of the oriented sheet 14. In the device support 9 of the lever 11 can be made in the form of a shaft 15, the length of which is comparable with the length of the largest sheet 14, while the upper part of the lever 11 can be made in the form of rigidly mounted on the shaft 15 and in parallel installed along the entire length of the length of a row of slats 16. In this case, the device contains only one carriage 5 fixedly mounted on the foundation.

The device works as follows.

The carriages 5 are set apart from each other, not exceeding the length of the sheet 14. A loading device (not shown) places the sheet 14 on the cutting frame 1 so that the longitudinal edge of this sheet protrudes from the side of the device beyond the lateral surface of the frame slightly exceeding the permissible positioning accuracy of the loading device when it is stopped, which is approximately 10 - 30 mm, depending on the weight of this device together with the sheet. In this case, the levers 10 and 11 are divorced and the stop 4 of the frame 1 is placed between ni-sh. Further, on each carriage 5, the power cylinder and its body 12 and the rod 13 start to move mutually, turning the levers 10 and 11 towards each other. In this case, if the upper arm of the lever 10 first abuts against the stop 4, then the cylinder body 12 stops and the rod 13 continues to move, turning the lever 1 1 until it touches the upper shoulder of the longitudinal edge of the sheet 14 .. With a further turn, the lever 11 moves the fox . t 14 relative to the frame until it is abutted against the lateral surface, frame 1 and the longitudinal edge of the sheet does not coincide with the lateral surface. cutting frame 1. Since frame 1 is mounted on rails 3 so that it is fixed in the transverse direction by wheels with two flanges, the lateral movement of frame 1 is also absent when it moves to the cutting position, the position of its side surface and the longitudinal edge of the oriented sheet is high; is.

If the upper arm of the lever 11 first moves to the edge of the sheet 14 when moving the cylinder body 12 and the rod 13, this lever will stop and lever 10 will rotate until it touches the stop 4, after which lever 10 will stop and lever 11 will begin to shift the sheet 14 to stop lever in the side surface of the frame 1.

The forces required to move the sheet in the direction perpendicular to its longitudinal axis are closed in the system frame 1, lever 11,
