Description

The inventive utility model relates to the field of processing paper, cardboard, thin flexible materials and can be used in lines for the production of corrugated cardboard for its transverse cutting into blanks of a given length from a continuously moving corrugated cardboard web.

A device is known for the transverse sections of blanks of a given length from a continuously moving web of material (patent for invention RU No. 2179514 dated 10.10.2000), where the segment of blanks has the direction of previously longitudinally cut strips of material in the upper and lower zones with upper and lower transversely cutting devices, mounted on a bed, the cutting organs of which, making translational movement across the blade, produce its cutting. Each cross-cutting device has its own electric drive, sensors for the length of the workpiece and engine shutdown, its own cutting body - a circular knife, freely suspended on two parallel branches of roller chains, tensioned on twin sprockets and driven by an electric drive with a frequency converter that allows you to adjust the linear speed of the cutting body.

The disadvantages of this device are the impossibility of cutting flexible materials (for example, thin, flexible, two-layer microcorrugated cardboard), in view of its “crushing” and shear along the cut line during cutting, the inability to mechanically stack cut sheets in a stack.

The purpose of the proposed utility model is to create a device capable of carrying out the process of transverse sections of a workpiece of a given length from a continuously moving flexible web of material with mechanized laying it in the foot.

This goal is achieved by the fact that the drive unit for supplying a flexible web of material, the unit for transverse cutting are combined in a single machine that is joined to the drive belt conveyor, the output of which is connected with the device for mechanized stacking of blanks in a stack on a lifting and lowering table-paver. The choice of stacker type is determined by the degree of flexibility of the material being cut and can be implemented in one of three options:

- adjustable guide lodgements - for a relatively rigid type of material;

- oscillating drive guide rollers - for flexible material;

- blowing with a slotted blower - for the most flexible materials.

On the bed of the cross-cutting machine (hereinafter referred to as SPR) there is a drive unit for refueling and promoting a flexible, continuously moving web of material, a unit for cross-cutting of a rotational type and a conveyor belt for selecting blanks. Figure 1 shows a General view of the SPR with one node of transverse cutting - a cut in a constant format for the entire width of the moving web of material. Figure 2 shows the nodes of the feed, transverse cutting, selection of blanks and two options for stacking them in feet on the table-paver. Figure 3 shows a third option for laying blanks.

Single transverse cutting machine (SPR) (Fig. 1, 2) has a frame 1 with located on it: drive unit for filling the web of material 2; a transverse cutting unit, consisting of a beam with a fixed knife 3 of the guillotine type, integral or integral, and a rotor with a movable knife 4, driven by a gear motor 5; belt drive conveyor selection of blanks 6; drive of the filling station and the selection conveyor 7. The device for the transverse cutting of workpieces also includes a table-stacker 8 with one of three (options 1 2, 3) stackers of workpieces in the foot: adjustable guide tool holders 9, swinging drive guide rollers 10, blowing flexible workpieces with a slot blower 11.

The transverse cutting device operates as follows: The strip of material being cut by the drive unit is directed to the rotary unit of the cross-cutting device. According to the signal of the workpiece length sensor (not shown in the figures), the working body of which has contact with the moving blade of the material being cut, the geared motor motor turns on (turns off), which drives the rotary knife shaft, which cuts the strip of the web of material across. The rotary movable knife is located relative to the fixed knife at a certain angle due to which, when the knife shaft is rotated, the cut is carried out according to the principle of scissors, a running cut point between the knives. When the engine is stopped, the cutting body is fixed in a strictly defined position, ready for the execution of the next cutting cycle. Cut blanks are selected by the conveyor belt and from it through the movable guide lodgements (option 1) or drive guide rollers (option 2), or by blowing the flexible sheet with the blower (option 3) are automatically stacked on the lifting-lowering table-stacker.

If there is a second transverse cutting drive unit in the SPR, it becomes possible to cut a material pre-cut along the web into two, variable in width of the web material, format.

Using this device allows the transverse cutting of a canvas of flexible materials and mechanize their stacking for further use in automatic lines, for example, for laminating microcorrugated cardboard.
