Description

CZ 31379 Ul

A device for automatically stacking multiple side-by-side flat objects

Technical field

The technical solution relates to a device for automatically stacking more side-by-side flat objects, in particular paper, foil, plastic and textile material.

BACKGROUND OF THE INVENTION

Known devices for stacking webs of material are designed such that a mechanical device places the web of material by swinging from above onto an already stacked stack of paper. The warehouse is usually carried out at the perforation and the mechanical device is synchronized with the perforation. However, complicated synchronization has to be used for this method of folding paper, and the need for synchronization increases when folding multiple unwinding paper webs in one operation. This complicated synchronization must ensure that, in the case of a plurality of unrolled webs, all paper webs are perforated in one plane and that the stacks do not grow. Such complex mechanisms are described, for example, in EP 2520526 or EP 2298681 or US 5030192.

The essence of the technical solution

The disadvantages of the known devices for stacking more side-by-side stripes of flat objects are eliminated by a device according to the invention which comprises a flat object container, feeds a unit located behind the container, a sensor that controls the unwinding of flat objects from the container or controls the speed of stacking flat objects, which aligns the unfolding flat objects before entering the movable folding table. SUMMARY OF THE INVENTION The movable folding table comprises a rotatably mounted first stacking belt and a second stacking belt, the movable folding table being supported in a linear guide formed from a fixed frame of the stacking device. The first stacking belt and the second stacking belt are arranged in triangles on rollers. The first rolls and the second rolls (9, 9.2) of each strip (8.1 and 8.2) are rotatably supported in the frame of the movable folding table, the third rolls are supported on the support members perpendicular to the frame of the movable folding table. The support elements on which the third cylinders are rotatably mounted are fixedly connected to the frame of the movable table. Under the third rollers, unidirectional rollers are mounted on the support elements through which a flat stacked item is guided from below between the first stacking belt and the second stacking belt. Each stacking belt is connected on a horizontal side to a fixing bar that is rigidly connected to a fixed stacking device. Above the stacking strips, abutment stops are placed above each stacking strip, which are also firmly attached to the frame of the stacking device. The frame of the movable folding table is connected to a mechanism which is controlled by the motor.

The advantage of the technical solution is that the simple construction of the stacking device, side-by-side strips of stacked objects always enter the folding table from below perpendicularly, which prevents the strips from twisting or jamming. By varying the width and length of the stacking table, very long folds of perforated stacked items can be achieved.

Example of technical solution implementation

Referring now to Figure 1, there is shown an apparatus 100 for automatically stacking a plurality of unwrapping flat perforated objects 20, such as paper tickets, side by side. The machine comprises a roll of paper webs 1, a feed unit 2 which is located behind the tray 1 and feeds the unwinding stacks of stacked tickets 20 into a guide bar 4 that aligns the unfolded flat ticket strips 20 before entering the movable folding table 7. Between the feeders a sensor 3 is provided by the unit 2 and the guide bar 4, which controls the input loop of the strips of the perforated objects 20 or controls the unwinding speed of the flat objects from the magazine 1 or controls the stacking speed of the flat objects entering the movable folding table 7. belt 8.1 and second stacking belt 8.2. The two stacking belts 8.1 and 8.2 are arranged in a triangle 10 and are supported on rollers 9. The first rollers 9, 9.1 and the second rollers 9, 9.2 of each stacking belt 8.1 and 8.2 are rotatably supported in the frame 7.1 of the movable folding table 7, the third rollers 9, 9.3 are mounted on the support elements 13 perpendicular to the frame 7.1 of the movable folding table 7, the support elements 13 being fixedly connected to the frame 7.1. The movable folding table 7 with stacking belts 8.1 and 8.2 is mounted in a linear guide 11 formed in a fixed frame 12 of the stacking device. Under the third rollers 9.3, on the support elements 13 are placed unidirectional rollers 5, which are guided perpendicularly from below between the first stacking strip 8.1 and the second stacking strip 82, i.e. between the shorter sides of the triangle 10 flat unwinding webs 20. from the bottom into the stack of already folded paper strips 20, the stacking strips 8.1 and 8.2 must be moved in the horizontal plane, i.e. in the linear guide 11 of the frame 12, but at the same time must roll on rolls 9.1 to 9.3. However, during this rolling, the stacking belts 8.1 and 8.2 must be rigidly connected to the fixed frame 12 of the stacking device 100. Therefore, the stacking belts 8.1 and 8.2 are connected to a fixing bar 14 which is anchored to the fixed frame 12 of the stacking device. When stacking the ticket strips 20 it must also be ensured that the stacked papers do not disprove when the movable folding table 7 is moved. For this purpose, between the fixing stops 14 above the stacking belts 8.1 and 8.2, there are flying stops 15 which are also fixedly fixed to the frame 12 of the stacking device 100. It is advantageous to set the flying stops 15 to the length of the perforation of the folded papers 20. the stacking step between the perforations of the folded tickets 20 is adjusted by the crank linear mechanism 16, which is controlled by the motor 17. The crank linear mechanism 16 is connected to the frame

Movable folding table.

The function description of stacking perforated paper strips includes:

- according to the length of the folded ticket strips 20 with the linear crank mechanism 15, adjust the step length of the linear movement of the movable folding table 7 to determine the fold line in the folded ticket 20 and also set the distance between the flying stops 15

- from the magazine 1, the folded ticket strips 20 are guided manually over the guide bar 4 between the unidirectional rollers 5 and further guided manually between the third rollers 9.3 and the second rollers 9.2 onto the surface of the first stacking strip 8.1 belt)

- on the first stacking strip 8.1, the guided strips 20 are aligned so that a first row of stacked ticket strips 20 is formed in the line of perforation and this first row is mechanically loaded from above by a flat sheet-like thrust element 18,

- a motor 17 is actuated to operate the linear crank mechanism 18, which controls the alternating linear movement of the folding table 7, whereby the folding table 7, which is housed in the linear guide 11 of the frame 12 of the device 100, begins to move to the left. When moving to the left of the folding table 7, the first stacking belt 8.1 and the second stacking belt 82 also move to the left.

8.1 and 82 are supported on rollers 9 which are supported in frame 7.1 of the folding table 7 and in a support element 13 connected to the frame 7.1, and wherein both strips 8.1 and 8.2 are still connected by a fixing bar 14

-?.

With the frame 12 of the device 100, with the linear movement of the folding table 7, the tensioning belts 8.1 and 82 also roll over the rollers 9, which rotate clockwise as the folding table 7 moves. This linearly rolling movement of the stacking belts 8.1 and 8.2 causes the ticket belts 20 to slide from below from right to left on the side of the second stacking strip 82 under the first manually positioned row of ticket belts 20,

- as soon as the folding table 7 operated by the linear crank mechanism 16 reaches the end of the set linear movement step in the linear guide 11, i.e. to the point of perforation of the folded ticket strips 20, i.e. to the left side of the movable folding table 7 operated by the motor 17 changes the direction of movement of the folding table 7 and starts moving the folding table 7 to the right,

- at the moment the folding table 7 moves to the right, the rotation direction of the rollers 9 and the rolling direction of the first belt 8.1 and the second belt 82 deposited on the rollers 9 also change. The rollers 9 start to rotate counterclockwise, causing the folded ticket strips 20 in the place of the line of perforation and their underfeed from the left - right side of the belt 8.1 under the last stored row,

as soon as the folding table 7 operated by the linear crank mechanism 16 reaches the end of the set linear movement step in the linear guide 11, i.e. to the point of perforation of the folded ticket strips 20, i.e. to the right side of the movable folding table 7 operated by the motor 17 changes the direction of movement of the folding table 7 and starts moving the folding table 7 to the left,

- when the folding table 7 moves to the left, the rotation direction of the rollers 9 and the rolling direction of the first belt 8.1 and the second belt 82 deposited on the rollers 9 again change. The rollers 9 start to rotate clockwise causing the folded ticket strips to bend 20 at the point of the line of perforation and their shifts from right to left on the side of the belt 82 below the last stored row,

- the alternating direction of the linear movement of the folding table 7 from left to right and right-to-left and the associated changes in the rolling direction of the stacking belts 8.1 and 82 are repeated after the specified number of stacked paper-tickets 20 has been stitched. stack of stacked tickets 20. It may now be followed by re-engaging the engine 16 and repeating stacking or the remainder of the unstacked ticket strips removed from rollers 9 and feed elements 2, 4 and 5.

Industrial applicability

The machine can be used to automatically stack multiple strips of perforated papers, such as tickets, flat sheets, flat textiles, or rubber strips.
