(54) DEVICE FOR LAYING THE SHEET MATERIAL INTO PACKAGES

. t

The invention relates to processing equipment for stacking and can be used for stacking sheets of ferromagnetic material in bags.

A device for stacking sheets in packages is known, comprising a feed roller, a stop for stopping the sheet and a receiving table. On the moving axes Q of the feeding roller table, there are installed c, spacing rollers, between which an abutment comes in, which provides for stopping the sheet at the end Jl.

A disadvantage of this device is the possibility of simultaneously laying sheets of different lengths and configurations in several packages.

The purpose of the invention is to expand the technological capabilities of the device 20. .

This goal is achieved by the fact that the stop for stopping the sheet is located above the working surface of the roller table and is made of magnetic material 25 of cylindrical shape.

FIG. 1 is a schematic image, but the proposed device; in fig. 2 is the same, top view in FIG. 3 is a diagram of sequential position of sheets.

when laying and positioning them in relation to the magnetic stop.

On the frame 1 of the device, end sprockets 2, enveloped by roller table 3, are installed. On top of the frame, guides 5 are mounted, to which the carriages 6 carrying magnetic stops 7 of cylindrical shape and sensors 8, for example contactless, actuated from a ferromagnetic material can move and secure. The carriages b are fastened with screws 9. Magnetic stops 7 for setting the sheet are installed at the minimum possible distance from the axes 4. In this example, the device is equipped with two magnetic stops for stopping the sheet for simultaneous typing of two packages. On the ribbed surface of the receiving table 10, fixed stops 11 and pushers 12 are installed, provided, for example, with a pneumatic drive. As stops 11; and the pushers 12 can be installed at any place on the receiving table 10. The movement of the roller table 3 is driven by the drive 13. The device works as follows. The stacked sheets, for example, long and short, go to the roller table 3. Upon further movement, the front ends of the sheets are picked up by magnetic stops 7 and stop, and the contact of the sheet with the stop for the stop of the Ea sheet takes place on the plane, and Hie rto the end face. The rear ends of the stopping sheets, bending under our own weight, fall under the next axis 4 and begin to lay down on the receiving table 10. After the last axis leaves under the sheet, the front 1 Sdyö11 sheet will be fixed on the magnetic stop to stop the sheet turning on the cylindrical surface of the latter (Fig. 3). The next axis 4 tears off the front end of the sheet from the magnetic stop 7 and the sheet is completely laid on the receiving table 10. In this case, the package of short sheets is typed faster than the package of long sheets. Due to the fact that the sheets are in contact with the stop for stopping the sheet with a plane rather than an end, and due to the cylindrical shape of the stop allowing the sheet to unfold, the sheet is detached without deformation of the latter. This ensures stacking of sheets of different lengths at the same time regardless of the difference in the distance between the working surface of the roller table 3 and the plane of stacking the sheet in packets of different grooves. In addition, stacking of sheets of complex configuration, such as an oblique edge, is provided.

Claims (1)

%. / due to the fact that as the height of the package is raised, the front edge of the sheet falls from a different height, the package itself is taught with an uneven end. To align the ends of the package, the fixed stops 11 and the pushers 12 serve. After the sheet has fallen onto the bag, the next sheet, under the sensor 8, gives the command to actuate the pusher 12, and the latter moves the sheet to the stop 11, and then moves to its original position to receive the next sheet. For a set of several packages of short sheets in one row, the carriage b is moved along the guides 5 and secured in place by the screw 9, the support 11 and the pusher 12 are rearranged on the receiving table 10 and the device is ready for the next package. Claim 1. Device for stacking sheet material in packages containing feed roller, stop for sheet shutdown and receiving table, characterized in that, in order to expand the device’s Jrehnologic capabilities, stop for stopping sheet is located above the working surface of the roller table and is made of magnetic material .. 2. The device according to claim 1, is different from the fact that the stop has a cylindrical shape. Sources of information taken into account during the examination 1.
