Definitions

  • the invention relates to a drive or folding mechanism for a device for laying an in particular unfolded fiber material web, in particular a paper web, a corrugated paper web or a corrugated cardboard web, in a fan-fold fold.
  • a corrugated track is often used for packaging purposes, for example by laying corrugated cardboard layers separated from one another for cushioning goods that are to be transported next to one another.
  • a corrugated cardboard blank can be contoured on one side or on both sides.
  • one side is formed by a corrugated paper layer to which a smooth paper layer is glued to form the other side.
  • the corrugated cardboard web can also be formed by several flat and / or corrugated paper layers placed one on top of the other to increase the buffering property of the packaging material.
  • the cuboid Leporello folding stack has the advantage of space-saving storage compared to the cylindrical take-up roll because, on the one hand, a higher material density is achieved due to the Leporello folding that the respective wave-valley shape of opposing folded layers can interlock, and on the other hand the cuboid Leporello folding stacks are simple and space-filling can be stacked next to each other.
  • the Leporello folding has the advantage that the unfolding Leporello folding is stationary and does not, as in contrast to the roll, perform a rotational movement during development, which requires special storage properties and a need for hut space .
  • these are usually made available on rolls at the end of the production process, so that the creation of a fan-fold pile would first have to unwind the fiber material web from the reels and bring the fan-fold fold.
  • a device for laying an in particular unfolded, endless fiber material web in a fan-fold fold is from DE 196 44 383 C1 known.
  • the Leporello folding device has a drive mechanism in the form of a translationally reciprocable conveyor belt pair with two vertically arranged drive belts. In order to achieve the fan-fold zigzag fold, the vertically aligned drive belts are shifted translationally back and forth in the horizontal direction.
  • a drive mechanism for a fan-fold direction in which a drive roller connected upstream of a pair of pendulum rods pulls a radial path from a material web source and feeds it to the pair of pendulum rods, which is intended to form the fan-fold fold by pivoting to and fro.
  • DE 196 64 858 discloses a drive mechanism for a fan-fold fold in which a pull roller pulls off the material web.
  • the draw roller is fixedly attached to the support frame of the device of the fan-fold device.
  • the fanfold is carried out using a swivel arm with two guide pins.
  • JP 11 255423 A shows a drive mechanism for fan-fold folding, with a pair of rollers oscillating with the delivery part.
  • the folding of the paper web is supported by a hold-down mechanism at the turning points of the fiber material web.
  • the object is to overcome the disadvantages of the prior art, in particular to provide a drive mechanism for a fan-fold device and a fan-fold device in which, with the simplest possible construction, space requirements are as small as possible clean fan-fold for the fiber material web at conveying speeds of over 30 m / min.

  • the drive mechanism comprises a pivotably mounted pair of rollers lying opposite one another, which form a passage gap for the material fiber material web and, in particular, can be rotated for conveying the fiber material web through the passage gap. It is this pair of rollers which is intended to oscillate back and forth by a drive for pivoting the pair of rollers.
  • the passage gap defines an exit delivery direction of the fiber material web in the conveying direction away from the passage gap, which can in particular be defined by mutually parallel tangents on the smallest passage of the passage gap.
  • the exit delivery direction for the fiber material web defined by the passage preferably oscillates back and forth about a vertical. It can pass through a pendulum center passage position in the vertical while pendulum outer reversal positions laterally limit the pendulum amplitude of the pair of rollers, in particular the exit discharge direction.
  • a device oscillating back and forth with the pair of rollers for guided guiding of the fiber material web towards the fan-fold fold is arranged downstream of the passage gap. In order to be able to swing back and forth with the pair of rollers, the guide device is firmly attached to them.

  • the guide device has a driver, in particular two driver plates or rods that lie opposite one another, in particular that are arranged parallel to one another.
  • the driver limits a receptacle for a fiber material web leaving the passage gap in both pendulum directions, so that the fiber material web is entrained in the respective pendulum direction when it is passed through the receptacle. In this way, the desired tensile stress of the fibrous material web is communicated when the fibrous material web is slightly pulled from the last folded fold to the opposite side.
  • the driver is designed as a driver rod, there may well be a free space between the pair of rollers and the driver rod. It is not necessary to continuously provide a full-surface guidance between the passage gap and the driver rod.

  • the most retracted position is in Figure 4 shown, namely when the exit discharge direction A coincides with a vertical V, so the pair of rollers 57 passes through the pendulum center passage position.
  • the setting of the length of the guide shaft 25, the distance of the free end of the guide device 17 to the fan-fold 3 and / or the distance of the free end of the guide device 17 to the passage gap 13 depends in the embodiment according to the Figures 4 and 5 from the pivot position of the pair of rollers 5, 7. It is clear that other control parameters, such as the conveying speed, can also be used to regulate the distance and regulate the length of the guide shaft. It is clear that this distance regulation can also be implemented continuously and depending on the operation, that is, without a fixed backdrop.
  • the pulley connecting rod drive is implemented by several drive pulleys, with a motor-side drive pulley 41 driving a first pulley 45 via a connecting rod 43, which is in engagement with an output pulley 47 via the belt 49 in order to prevent the reciprocating movement of the pair of rollers 5 To realize 7.
  • the pendulum drive according to the Figures 6a to 6b is designed to convert a continuous rotational movement of the drive pulley 41 into a back and forth pivoting movement of the drive belt pulley 47 and thus of the pair of rollers 5, 7.
  • the connecting rod 43 is designed to be slightly shorter than the central axis distance between the drive pulley 41 and the first belt pulley 45.
  • the angular speed of the pendulum drive is negligibly low starting from the pendulum center passage position and gradually increases and reaches the highest angular velocity in position 2. In this way it is ensured that the exit delivery direction A does not remain in the reversing position for too long, but is brought back into the passage position in an accelerated manner.
  • the angular velocity is highest in positions 1, so that the corrugated cardboard paper material is conveyed the fastest towards the fan-fold fold in order to satisfy a higher material requirement.
  • the angular velocity decreases significantly from position 1 to position 2 and essentially reaches a minimum at position 2. From position 2 the angular velocity increases again and reaches its maximum in position 3, from where the angular velocity gradually decreases again and the minimum in position 4 reached. From position 4 to 1, the angular velocity increases again significantly.
  • the angular position profiles in particular the angular velocity profiles, run in opposite directions and are coordinated to the extent that less corrugated cardboard paper web material is made available in positions 2 and 4 and the positions are left more quickly, with more corrugated cardboard paper web material being made available in positions 1 and 3 and the positions are left more slowly. It turned out that with the above Angular speed settings a precise and uniform Leporello folding can be achieved even with regard to higher conveyor speeds, which can be over 40 or 50 m / min.
  • a pair of left and right low-pressure rams 51, 53 is provided for a leporello folding device 50 according to the invention, which can be shifted towards and away from the leporello fold 3 essentially in the vertical direction V.
  • the press-down rams 51, 53 can extend over the entire width of the web of corrugated cardboard.
  • the press-down rams 51, 53 are operated by an independent drive 55, which provides a continuous rotary movement of a drive disk in only one direction of rotation.

  • the press-down ram 51, 53 has a pressure engagement position in which the fan-fold is depressed for folding, and a release position in which the press-down ram 51, 53 releases the fan-fold 3.
  • the low-pressure ram comprises a comb structure 61 made up of several blunt ram prongs 63 arranged in a row, with adjacent ram prongs 63 being separated from one another at regular intervals by recesses.
  • the Leporello folding device has a retaining device in the form of a pair of left and right retaining feet 67, 69, each of which has a substantially horizontally extending finger arrangement.
  • the horizontal finger arrangement is dimensioned in such a way that it can move into and out of the recesses in the comb structure 61 of the press-down rams 51, 53.
  • the restraint device is connected to a drive device (not shown in more detail) which enables the respective restraint foot to be pivoted in and out substantially horizontally.
  • the retaining foot is dimensioned in such a way that it partially protrudes beyond the Leporello fold edge.
  • the purpose of the retaining device is to prevent the fan-fold folding from unfolding when the press-down ram 51, 53 moves away from the respective side of the fan-fold.
  • the restraint has a Active position in which it prevents the fan-fold 3 from unfolding, and a passive position in which it releases the fan-fold 3.
  • the press-down stamps and the retaining device can be structurally coordinated with one another in such a way that they come into contact with the fan-fold fold in the width direction of the fan-fold fold essentially at the same position adjacent to the respective fold.
  • the press-down rams and the retaining device have an axially symmetrical structure to a vertical axis V.
  • both the restraint device and the low-pressure device each have their own kinematics of travel that are coordinated with one another.
  • the respective left or right press-down ram should be moved into the release position when a respective left or right retaining foot has assumed the active position. If a respective left or right press-down ram is still in the pressure engagement position, a respective left or right retaining foot moves into the active position.
  • at least one of the four left and right retaining feet and press-down rams is in the active or pressure engagement position.
  • the guide device 17 is in the process of pulling the corrugated cardboard paper web from left to right from the folded edge that has just been implemented, while at the same time the coating device 37 smooths the layer underneath and the left retaining foot 69 keeps the fan-fold 3 stable.
  • the left press-down ram 53 is just about to press down on the fan-fold fold in order to apply a folding force to it and thereby to introduce an irreversible fold in the web of corrugated cardboard.
  • the press-down ram exerts a pressing force in its pressure engagement position, as shown in FIG Figure 9b is shown, the retaining foot 69 must first be pivoted out of its active position.
  • the upper layer of the fan-fold 3 can easily be placed further on the finger arrangement without the right retaining foot 67 having to be moved into the passive position, which is shown in FIG Figure 9c is shown.
  • the right-hand press-down ram 51 is brought into the pressure-engagement position in order to produce the fold.
  • the right retaining foot 67 can remain in the active position, and the left press-down ram 53 can be brought to the release position, while the left retaining foot is still holding down the fan-fold 3.
