Definitions
- the invention relates to a needle roller for perforating or picking up material pieces or webs according to the preamble of claim 1 and to a method for perforating or picking up material pieces or webs according to the preamble of claim 10.
- Needle rollers are often used to perforate webs of material, such as paper webs, from which pieces of tubing and ultimately sacks or bags are made. Such perforations are often created to vent such bags after filling can. The same applies to bags in which, for example, bread is packed. Here, the perforations produced in this way serve to remove the moisture.
- a device incorporating such needle rollers is described in EP 0 776 741 A1. Also, printed products are often provided with perforations as disclosed in US Pat. No. 4,055,101.
- needle rollers are also used for receiving pieces of material when it is necessary to remove a separated piece of material from the Matehaliser.
- One application is the removal of so-called flaps, ie pieces of material, in the course of the production of paper bags from sheet-like paper.
- needle rollers are rotatable in the machine frame or other components that are held in place during operation (hereafter For reasons of simplicity, the peripheral speed is equal to the transport speed of the webs or pieces in some applications, while in other applications the peripheral speed of the needle roller may differ from the transport speed
- the needle rollers may represent various embodiments However, common to all embodiments is a needle roller body which can roll with its outer circumference on the material web.
- the needles protrude beyond the outer surface of the needle roller body for piercing into the piece of material or into the material web.
- a common problem with needle rollers is the release of the piece of material or the web after the piercing.
- the needles and the web to solve again, without the needles influence, for example, on the
- the object underlying the present invention is therefore to propose a needle roller and a method in which or in which the needles and the material piece or web can be separated from each other in a simple manner.
- a needle roller which in addition to the features of the preamble of claim 1 also includes its characterizing features, as well as by a method according to claim 10.
- the needles are displaceable relative to the needle roller body.
- the needles after the Reception of the piece of material partially or completely back into the needle roller body, so that the piece of material rests on the outer surface of the needle roller body and is completely or at least largely stripped by this surface of the needles.
- a piece of material that has been taken by the needle roller can now be collected in a waste container or removed by another means, such as a nipple.
- the needles are said to have returned to their original position in this process after a complete rotation of the needle roller.
- the effect of the device according to the invention is especially great when the needles are once fully drawn into the needle roller body during this revolution ("low point") and once their maximum position, ie the "high point” (maximum distance of the needle tips from the outer circumference of the needle roller body). achieved. It is also conceivable that the needles have twice reached the positions described in each round.
- At least one needle bar is provided, on which a plurality of needles are arranged.
- This needle bar then extends parallel to the axis of rotation of the needle roller.
- a needle carrier which carries needles or the at least one needle bar.
- the needle carrier also advantageously extends parallel to the axis of rotation of the needle roller.
- the needle carrier is movable in the radial direction of the needle roller. It is advantageous in this case if the needle carrier can be moved on a cutting plane, which is spanned by the axis of rotation of the needle roller and a radial direction.
- the needle carrier can be guided by guides, in particular linear guide elements such as rails or sliding surfaces. If, on both sides of the needle carrier, needles are arranged parallel to the guides, then the one needle set can reach its peak while the other needle set can reach its bottom, and vice versa. With such an embodiment of the needle roller so two pieces of material can be removed by the movement of only one assembly from the material flow.
- the at least one needle bar can be detachably fastened to the needle carrier.
- This is to be provided in particular if two or more needle bars are provided on the needle carrier.
- one of the needle bars can be removed, so that only one piece of material is received per revolution of the needle roller.
- the needle bars may be screwed to the needle carrier. Other types of attachment are conceivable.
- This roller is fixed relative to the machine frame during rotation of the needle roller so that rotation of the needle roller provides movement of the needle carrier relative to the needle roller body.
- the guide curve is designed as a recess in the end face of the needle carrier.
- the roll can also roll on a control or guide curve, which is not or at least not arranged directly on the needle carrier.
- the guide curve has the shape of an ellipse. It is advantageous if the small semi-axis of the ellipse runs substantially perpendicular to the direction of movement of the needle carrier. In this elliptical shape, there are no major changes in the forces acting, so that the entire device is operated as low as possible wear.
- said elliptical shape of the guide curve with the guide direction of the needle carrier act from the roll and the Guides exerted forces not only radially outward, but also radially inward. If the latter were not the case, springs would have to be used, but their restoring force would be severely limited. The combination mentioned is therefore of great advantage.
- the already mentioned roller is arranged on a block.
- This block can be a cylindrical body.
- This block is rotatable relative to the needle roller and relative to the machine frame. This axis of rotation of the block is aligned with the axis of rotation of the needle roller. It is advantageous if two such blocks are provided, one at each end. The block can even be twisted during operation of the needle roller.
- the axis of rotation of the roller is arranged parallel, but eccentric to the axis of rotation of the block.
- a motor preferably an electric motor, is provided, with which said block is rotatable. If two blocks are provided, it is advantageous to couple them in a suitable manner, so that their rotation runs synchronously. This can be done for example via a geared shaft whose gears act on gears of the blocks.
- FIG. 1 is a side view of a first embodiment of a bag machine, in which a needle roller according to the invention is advantageously used
- Fig. 2 side view of a second embodiment of a
- FIG. 3 shows a detail view of a tear-off, in which a inventive
- Needle roller can be used advantageously,
- FIG. 4 shows a longitudinal section through a needle roller according to the invention
- FIG. 5 shows V - V from FIG. 4
- Fig. 1 shows a device 1 for the production of bags.
- the device 1 comprises an unwinding device 2, to which a material web 3 in the form of a roll 4 is fed. Starting from this winding 4, the web 3 is guided by guide rollers 5 of the cross-cutting station 6 or perforating station 6.
- This station 6 comprises one or more cross-cutting or transverse perforating knives not shown in detail, which circulates on a roller 7.
- the web 3 runs in this station 6 via a counter-pressure roller 8, which has the main purpose to provide the necessary for the cutting or perforating counter pressure.
- a tube 10 is formed from the material web 3, by the web 3 by means of guide elements, such as guide plates, taken laterally, so that the edges of the web subsequently overlap.
- the subsequently overlapping regions were already provided by means of the longitudinal glue 26 with a suitable adhesive.
- the paper web and gussets can be inserted. The insertion of the gussets can also be done after the hose formation.
- the tube 10 is now usually continued in the transport direction z.
- the tube 10 is singulated in the first tear-off 11 to pieces of tubing 12.
- the tube 10 is guided through the nip of a first pair of rollers 13.
- this passes into the nip of a second pair of rollers 14.
- the rollers of the second pair of rollers have constantly or at least temporarily a greater peripheral speed than the rollers of the first pair of rollers 13, the peripheral speed advantageously coincides with the transport speed of the tube 10.
- the second pair of rollers 14 engage the tube 10. This can be done by entering the leading end of the tube in the nip of the second pair of rollers.
- the rollers of the second nip 14 can also be moved relative to the hose 10, for example vertically, and applied to the hose.
- the tube ruptures along the cut or perforation introduced into the web at station 6.
- the piece of tubing 12 torn off from the tube now enters the floor gluing and floor folding station 15.
- the piece of tubing 12 is held on the floor maker cylinder 16.
- the forward-running tab of the tube piece which is usually components of the underside and the top is projected over, folded, so that parts of the lower layer rests after folding on the outside of the upper layer.
- the tab and / or the region of the outer side of the upper layer on which the tab rests after folding over provided with an adhesive, such as glue.
- the glue application device which is symbolized in FIG. 1 by the glue cylinder 17, serves this purpose.
- This tear-off station 18 is thus arranged downstream of the bottom maker cylinder 17.
- This station is basically constructed like the first tear-off station 11 and operates analogously. The distances between the two nips are set so that the nip of the roller pair 19 only the
- the bags are usually arranged vertically. From this table 22, the bags can then be removed in batches in a suitable manner.
- FIG. 2 again shows a device according to FIG. 1.
- the roller 50 of the roller pair 19 is designed as a needle roller, which is explained in more detail in Figure 3.
- the roller 51 is designed accordingly as a counter-pressure roller, which may include depressions into which the needles can dip. These depressions can be configured, for example, as boreholes or as grooves.
- Above the Needle roller 50 is provided as a suction configured Abstreif Marie, which has the purpose of removing a received in the nip by the needle roller 50 portion of material again from the needle roller 50.
- FIG. 3 shows an enlarged view of the roller pairs 19 and 20 of the second tear-off station 18.
- the roller 50 of the roller pair 19 is equipped with needles 55, two of which can be seen. These needles 55 are slidably mounted within the roller 50 and are moved out of the peripheral surface of the roller 50 just before or when they reach the counter-pressure roller 51. At this moment, the material section 38 should be detected. The tearing off of the material portion 38 is accomplished either by the retention by means of the needles 55 or by the material portion being held in the nip of the rollers 50 and 51, or by both.
- the needles 55 can be retracted again within the body of the roller 50, so that the suction of the material section is facilitated.
- the extension and retraction of the needles can be done for example by a guide surface, not shown.
- the needles may be spring-loaded, for example, so that they are in the basic position within the roll body. To extend the needle, these can then run over a guide surface, which is arranged so that the needles are pressed against the spring force to the outside. However, the needles can also be moved in another direction in the direction of the double arrow R, which indicates the radial direction of the roller 50.
- controllable pneumatic cylinders are conceivable.
- the peripheral speed of these rollers is substantially equal to the transport speed with which the bags or pieces of tubing are transported through the apparatus.
- the peripheral speed of the rollers 50 and 51 is smaller than this at least in the period between the detection of the material portion 38 and the tearing Transport speed to allow the tearing in the first place. Since, however, the average rotational speed, ie the distance after a complete rotation of the roller 50 divided by the associated time, must be equal to the transport speed, the roller 50 must be nonuniformly, that is driven with non-uniform angular or peripheral speed. This can be done for example via a known non-uniformity gear or a separate servo motor.
- the phase angle of the rollers 50 can be adjusted in the direction of the arrows ⁇ and - ⁇ in order to be able to process tube pieces or bags of different formats.
- FIG. 4 shows a preferred embodiment of a needle roller 50 and in particular the control of the displacement of the needles within this needle roller.
- the needle roller 50 initially comprises a cylinder body 60 which is designed as a hollow cylinder and which has a central opening 62 at its end faces 61. Externally, another hollow cylinder 63 is attached to one end face.
- the cylinder body 60 and / or, as shown in FIG. 4, the hollow cylinder 63 are rotatably supported by bearings 64 in the machine frame 25. At least one of the hollow cylinder 63 is acted upon by a drive with a torque.
- the drive may, for example, act on a toothed belt which transmits the drive torque to the hollow cylinder 63 by means of gears, which thus acts as a shaft.
- the hollow cylinder 63 may also be driven by its own motor. This drive arrangement can be gearless.
- the electric motor 77 arranged on the machine frame drives a gear wheel 78, which meshes with the drive gear wheel 79, which is fastened to the hollow cylinder 63.
- Another cylinder 65 penetrates both the hollow cylinder 63 and the central opening 62 and thus projects into the interior of the cylinder body 60.
- the hollow cylinder 63 can still on the cylinder 65 support.
- This cylinder 65 can be fixed to non-illustrated parts of the machine frame 25, but can also be rotated relative to this. This twisting possibility, as will be described below, serves to adjust the needles relative to the outer surface of the cylinder body 60.
- a needle carrier 67 is slidably mounted in guides 68, so that it is displaceable in the direction of the double arrow R relative to the cylinder body 60 (see Figure 5).
- the guides 68 consist in the embodiment shown in Figure 5 of two plane-parallel planes, which represent slip planes for the needle carrier. But you can basically be designed differently for this purpose, as long as they allow the displacement of the needle carrier 67 in the direction of the double arrow R.
- the needle carrier 67 carries on each of its two side surfaces a needle bar 75, which in turn each carry a row of needles 72 which can pass through bores 73. The bores are introduced into a closure bar 88.
- This locking bar 88 provides an elevation 56 opposite the outer surface 74, which ensures that the material portion can be torn from the bag.
- the needle roller and the platen roller 51 have no permanent contact and do not hold the material portion firmly.
- the elevation 56 passes the platen roller, the portion of material is firmly gripped and thereby torn off the bag while the portion is simultaneously received by the needles.
- the closure bar 88 may be releasably secured to the cylinder body 60 by suitable fasteners such as screws.
- the needle bars 75 may also be fastened to the needle carrier 67 with screws 76 (see FIG. 6).
- the needle bar can be easily removed.
- the resulting recess of the outer surface 74 can now be closed by a cover, not shown.
- Needle roller 50 then operates with only one needle bar and removes only one section of material 38 per turn (usually two).
- the needle roller is adaptable to particularly long lengths of the bag 39.
- the needle carrier 67 has elliptical recesses 70.
- rollers 71 which are fixed to the needle carrier 67 facing the end face of the cylinder 65, wherein the axis of rotation 87 of the roller 71 is not aligned with the axis of the cylinder 65, but is arranged eccentrically to this.
- the roller may be rotatably mounted on the cylinder 65.
- FIG. 6 shows the same roller 50 as FIG. 4, but further rotated by an angle of 90 °.
- Cylinder body 60 sunk.
- the lower needles 72 '("6 o'clock position") are extended as far as possible and project beyond them
- Cylinder body 60 is rotated in accordance with the arrow D, so remains as described, the roller 71 in position. However, the elliptical recess 70 rolls with the edge surfaces on the roller 71. Since the needle carrier is not freely movable, but only in the direction of the arrow R is displaceable, the needle carrier 67 is acted upon by the action of the roller 71 on the edge surfaces of the elliptical recess 70 with a resultant constraining force, which points in the direction R.
- the cylinders 65, 65' can now be rotated relative to the machine frame. This is possible even during operation of the device according to the invention. With the rotation of the cylinder 65 and the axis of rotation 73 of the roller 71 is pivoted by the same angular amount, which has the consequence that also the position in which the needles 72 and 72 'are extended as far as possible, is changed by this angular amount.
- a drive 80 for example a servo motor, is provided which is fastened to the machine frame 25 via suitable holders 81.
- the shaft 82 of the drive 80 carries a gear 83 which meshes with a drive gear 84 arranged on the cylinder 65.
- the drive gear 84 in turn drives another gear 85, this an actuating shaft 86 and the latter in turn a gear 85 'at.
- Gear 85 ' meshes with the drive gear 84' which is secured to the cylinder 65 '.
- the synchronization arrangement ensures that the drive gear 84' and thus the cylinder 65 'is equally adjusted.
- Said synchronization arrangement is shown only as an example, other types of arrangements are equally conceivable. In particular, can be dispensed with a motor adjustment for cost reasons and a manual adjustment by means of suitable hand wheels or levers are provided.
