Definitions

  • the invention relates to a device for deformation, in particular for punching and / or embossing blanks or tapes, in particular made of cardboard, with a table device which bears protruding deformation elements on the processing side, and with a roller device for pressing the blank or strip against the deformation elements, table - And roller arrangement can be moved relative to one another parallel to the processing side by means of a drive.
  • Various devices are known for punching and embossing blanks or strips. Basically, they have a processing table, which is usually provided with deformation elements on the top. These are essentially vertical punching knives or embossing bars.
  • the devices In order to press the material web to be processed against these deformation elements, the devices have pressure elements in the form of press rams or cylindrical or conical pressure rollers. The latter have the advantage that a high local stamping or embossing pressure can be generated due to the line contact of the jacket with low forces.
  • DE-GM 78 31 892 a pair of pressure rollers arranged one above the other simultaneously over the top and bottom of a flexible, however, to move the stationary work table. Similar arrangements can be found in DE-OS 36 14 575 and DE-OS 21 56 829 with the difference that pressure rollers are only moved over the top, which is also the processing side.
  • DE-PS 36 0 ⁇ 8 113 shows a kinematically reversed solution, in which fixedly mounted pressure rollers are provided on the top and bottom of a flexible processing table and the processing table with the blank to be processed is moved through the press nips formed by the pressure rollers.
  • the known devices can sometimes only be operated discontinuously. Their flexibility in terms of the type and extent of the deformations is also insufficient compared to today's requirements.
  • the invention is therefore based on the object of designing the simplest possible device of the type mentioned at the outset in such a way that blanks or strips can be processed as quickly and flexibly as possible.
  • the table arrangement has two processing tables with deformation elements and that the roller device has two pressure roller units, each processing table being assigned its own pressure roller unit and the processing tables and / or the pressure roller units being driven in opposite directions.
  • the alternative with oppositely moving pressure roller units and stationary processing tables is particularly advantageous because it can be designed in a structurally simple manner and enables the blanks or strips to be pulled through quickly and easily.
  • the processing of the blanks or strips is distributed over two processing tables within one device. This leaves it for example to only provide punching knives on the first processing table in the processing direction and only embossing strips on the second processing table, i.e. to distribute punching and embossing over two work steps.
  • the moving parts of the device are driven in opposite directions, so that no free inertia forces occur during their acceleration and deceleration, so that short cycle times can be achieved with a simple and therefore inexpensive device construction.
  • the basic idea of the invention can be realized in any configuration of the pressure roller units, that is to say also in those which have one or more pressure rollers on both sides of the processing tables, the processing tables being able to be rigid or flexible. For most purposes, however, it is sufficient if the pressure roller units are arranged only adjacent to the machining sides of the machining tables, which presupposes the rigidity of the machining tables, and if the pressure roller units each have only one pressure roller.
  • a transport device for transporting the blanks through the device which has transport elements for gripping the blanks on an edge lying transversely to the transport direction, and that the pressure rollers have recesses on the circumference which are designed in this way and are arranged so that they are opposite the transport device in the region of the dead center of the roller movements so that a collision with the transport elements is avoided.
  • This can be designed in such a way that the pressure rollers have a smaller diameter over a first circumferential section than over a second circumferential section, the second circumferential sections interacting with the deformation elements during the movement over the processing tables. This training enables it to arrange the usual transport devices in these areas without collisions between the pressure rollers and the transport elements.
  • At least one guide device is provided for the precise rotation of the pressure rollers.
  • This guide device can be designed as one or more roller tracks on which guide wheels seated on the axis of rotation of the pressure rollers roll. This can also be done in such a way that at least one of the roller tracks is designed as a toothed rack and the guide wheels are designed as toothed wheels. Due to the positive engagement, it is ensured that the rotational position is always such that a collision between the transport element and the pressure rollers is excluded.
  • the processing tables are expediently arranged next to one another in a plane and preferably so that the processing sides of the processing tables lie horizontally on the top.
  • This conventional arrangement has proven itself in single table devices. However, this does not conflict with arranging the processing tables vertically and with their backs facing each other.
  • the drive is designed such that the speed of the movement of the pressure roller units and / or the processing tables has a maximum in the middle of the path and does not decrease linearly to the end points of the path. This should preferably be a sinusoidal movement, as is caused by crank drives.
  • the pressure roller units are held on both sides on drive belts, for example drive belts designed as toothed belts, which can be moved back and forth via the drive.
  • the drive should at least have a meshing gear pair that cooperates with the drive belts, the gear pair being driven by a crank mechanism.
  • the angle of rotation of the gear pair (s) should be adjustable.
  • the drive has a motor and a gear unit which causes the opposite movement.
  • the gear unit should be designed in such a way that the dead centers of the roller movements of the pressure roller units lie outside the processing tables. This design is particularly advantageous if the pressure rollers have recesses in the sense mentioned above in order to avoid a collision with the transport elements.
  • At least one crank drive is particularly suitable as a gear here, expediently with a common crankshaft which has two crank pins offset by 180 °, which are connected to the pressure rollers and / or the processing tables.
  • a step gear can be connected upstream of the gear.
  • Such a stepping gear converts the continuous rotary movement coming from the motor into a stepping movement of the output shaft, with the aid of a globoid roller on the input side and an output disk provided on the circumference with roller bolts.
  • the advantage of such a step mechanism is that the Globo ⁇ d roller enables a particularly smooth and low acceleration movement sequence of the opposing elements. Operation and motor should preferably be arranged between the processing tables in order to use this space.
  • roller axes of the pressure roller units are inclined to the deformation elements. In this way, there is at most point contact with elongated deformation elements and not line contact. This allows punching and Emboss the blanks or strips with much less force.
  • the device (1) has two stationary processing tables (2, 3), which are arranged horizontally next to one another and rest on a device frame (not shown here). There is a frame on the top of each of the processing tables (2, 3) (4, 5) fixed. In the frame (4) lying first in the machining direction, vertically upright punching knives - designated by way of example (6) - are arranged. In the other frame (5) there are also vertically upstanding embossing strips - designated by way of example with (7) - the embossing stamp.
  • two cylindrical pressure rollers (8, 9) are arranged in such a way that their roller shells (10 ⁇ , 11) have horizontal surface lines. They can be moved horizontally in the directions of the double arrows (A, B), these directions being inclined at a small angle to the sides of the frames (4, 5).
  • the stub axles (12, 13) and (14, 15) of the pressure rollers (8, 9) are guided in slot guides (not shown here) in such a way that they carry out a horizontal translation movement over the processing tables (2, 3). In Figure (1) they are located near the outer end points.
  • crank rods (16, 17) or (18, 19) are connected to crank rods (16, 17) or (18, 19).
  • crank rods (16, 17) or (18, 19) on one side each lead to a common crank mechanism (20 ⁇ , 21). Both crank drives (20 ⁇ , 21) are connected by a common drive shaft (22).
  • crank mechanism (20 ⁇ ) seated at the free end of the drive shaft (22) has two crank disks (23, 24) which are connected via a crank pin (25) to which the crank rod (16) is articulated.
  • crank pin (25) On the free outside of the outer crank disk (24) there is another crank pin (26) which is offset by 180 ° from the crank pin (25) and on which the crank rod (17) is articulated.
  • crank mechanism (21) located on the other side has three crank disks (27, 28, 29), which are each connected via crank pins (30 ⁇ , 31) offset by 180 °. On one crank pin (30 ⁇ ) are the crank rod (19) and on the other crank pin (31) the crank rod (18) articulated.
  • Another section of the drive shaft (22) adjoins the crank disk (29). It leads into the driven side of a stepping gear (32) and is connected on the inside to a driven pulley which carries on its jacket a plurality of roller bolts which are freely rotatable about axes extending in the radial direction.
  • the roller bolts engage in a Globo ⁇ d roller, which carries cams on its jacket, on which the roller bolts are supported.
  • the globoid roller is connected to an electric drive motor (34) via an input shaft (33).
  • the drive motor (34) performs a constant rotary movement. This is converted into a stepping movement in the stepping gear (32).
  • the drive shaft (22) carries out a rotary movement of 180 ° with each step. As this also causes the crank pins (25, 26, 30 ⁇ , 31) to be pivoted through 180 ⁇ °, the result is that the pressure rollers (8, 9) are moved from one dead center position to the other dead center position.
  • the cams on the Globoid roller within the stepping gear (32) are shaped so that a gentle, i.e. smooth movement with low accelerations is guaranteed.
  • FIGS. (2) and (3) The sequence of movements of the pressure rollers (8, 9) is illustrated in more detail in FIGS. (2) and (3).

  • Figure (2) shows the position of the pressure rollers (8, 9) in the outermost dead center position, in which the roller shells (10 ⁇ , 11) of the pressure rollers (8, 9) no longer come into contact with the punching knives (6) or embossing strips (7) to have.
  • the crankpin (25, 26) are accordingly located on the side of the crank rods (16, 17) articulated on them. In this position, a sheet blank can be placed on the punch knives (6) or embossing strips (7) with the aid of a conventional transport device, not shown here, in a precisely defined position.
  • the transport device can be a transport device that moves over both processing tables (2, 3) in the plane of the drawing and that successively cuts into the device (1).
  • the drive shaft (22) is turned by 180 °. Accordingly, the crank pins (25, 26) pivot by the same amount and then assume the position shown in Figure (3).

  • crank pins (26, 27) and the center point of the drive shaft is dimensioned such that when the drive shaft (22) rotates 180 °, both pressure rollers (8, 9) are moved over the entire surface, which the frame (4 , 5) is narrowed down. The pressure rollers (8, 9) then assume the inner dead center position, as can be seen in FIG. (3).
  • the punched blank is moved horizontally with the transport device from the first frame (4) to the second frame (5) and deposited there.
  • the embossed blank located in the frame (5) is removed and, if necessary, fed to a further station for breaking out the punched sections.
