Definitions

  • the invention relates to a device for handling the used packaging of a roll of material web behind a unpacking station for removing end covers and a peripheral sleeve and a method for handling the used packaging of a roll of material, in which the end packaging and the peripheral sleeve are removed from the roll.
  • Rolls of material web for example paper rolls, are packed for the purpose of transport and storage. In this case, they are usually wrapped in multiple layers with a packaging web, for example made of packaging paper, the individual layers being glued to one another in many cases. The envelope or circumferential envelope is then folded in at the end faces and closed with an end cover.
  • a packaging web for example made of packaging paper
  • the roll Before further processing of the roll, for example before printing on the paper web, the roll must be unpacked. It is common to first remove the end packaging by inserting a knife between the end of the roll and the end packaging. The roll is then rotated and the knife held. After a complete revolution, the end packaging is detached and can be removed, for example by placing it in a collection container. The other face is treated in the same way.
  • the roll is now only wrapped. This is cut open or blown open in the longitudinal or axial direction.
  • the covering then falls off at least on one side of the roll.
  • the other side may have to be cleared by hand or mechanically by rotating the roller on its support rollers.
  • the roll can then be removed and sent for further processing.
  • the circumferential envelope or packaging then lies on the floor and must be handled further for disposal.
  • the circumferential envelope forms a relatively large and thus heavy and, above all, relatively rigid layer. When spread out, their area can be more than 10 m2.
  • a unpacking station for paper rolls is known for example from US-A-50 16 429.
  • the paper roll to be unpacked is placed on rotating support rollers. Holding devices are brought up to the front of the system. Knives are attached to the holding means. When the carrier rollers rotate and thus also rotate the paper roll to be unpacked, the knives separate the end packaging from the paper roll from. A knife can then be moved axially over the roller to release the peripheral packaging.
  • This object is achieved in a device of the type mentioned at the outset by means of a folding device which folds the circumferential envelope together and presses it flat and a transport device which is arranged between the unpacking station and the folding device.
  • the transport device thus conveys the circumferential envelope released from the roll to the folding device.
  • the folding device collapses the circumferential envelope in multiple layers and presses it flat, so that a relatively compact structure is formed which can be handled more easily.
  • the folding device can be arranged at a certain distance from the unpacking station. It can therefore also take up a certain space. Accordingly, the folding device can be designed so that it can also fold and press stiffer materials. The device can thus be used relatively flexibly.
  • the folding device preferably has a winding device, in particular a winding shaft, which winds the circumferential envelope into a winding, and a downstream squeezing arrangement, in particular a squeezing roller arrangement, which compresses the winding.
  • a winding device in particular a winding shaft
  • a downstream squeezing arrangement in particular a squeezing roller arrangement
  • compresses the winding As a result, the circumferential envelope is folded and flattened using relatively simple technical means.
  • the circumferential cover can also be wound up with a relatively small amount of force even if the circumferential cover is stiffer.
  • the winding thus formed can then be compressed or squeezed, wherein the printing direction is substantially perpendicular to the axis of the winding. This requires a relatively large amount of force. However, this force can be easily applied because a wrap is much more manageable than an extended circumferential envelope.
  • the squeeze roller arrangement has a roller gap which is arranged essentially perpendicular to the axis of the winding shaft. If the winding is now moved along its axis, it can pass through the nip roller arrangement. As a result, a rapid compression of the winding is achieved. In addition, the entire wrap does not have to be compressed at once. Rather, it is gradually compressed over its length, which significantly reduces the effort.
  • a wiping device is advantageously arranged adjacent to the winding shaft and can be moved in the direction of the longitudinal axis of the winding shaft. With the help of the stripping device, the winding can be removed from the winding shaft. It is hereby achieved that the winding can be forcibly inserted into the nip roller arrangement.
  • the winding shaft has an axially extending recess into which the stripping device engages.
  • the winding is gripped with the full thickness over part of its circumference. When stripping, no axial displacements of the individual layers of the winding can occur. This increases the reliability of the device.
  • a cutting device is advantageously connected downstream of the nip roller arrangement.
  • the compressed wrap can be broken down into handy pieces. These pieces are smaller in size and lighter in weight, which makes them easier to handle.
  • a collecting container is arranged below the cutting device, one side wall of which is located below the space between the cutting device and the squeeze roller arrangement. The parts of the winding separated by the cutting device thus fall directly into the collecting container, so that further manual handling is unnecessary.
  • the squeeze roller arrangement preferably has at least one driven roller.
  • the nip roller arrangement can then be used simultaneously to pull the winding from the winding shaft or from the winding device. This further simplifies handling.
  • a control device which controls the feed of the roll through the nip roller arrangement.
  • the control device controls the feed via the driven roller in such a way that only a certain length of the compressed roll is passed through the cutting device. Then it stops the driven roller. The cutter can cut off the length and the process starts again.
  • control device controls the feed so that the piece of the winder remaining after the last cut of the cutting device has a predetermined minimum length which is shorter than the distance between the squeeze roller arrangement and Cutting device is. Over the minimum length, it can be ensured that even the last piece of the roll, which is no longer cut, falls into the collecting container without the collecting container having to be arranged directly under the nip roller arrangement. In addition, this control can ensure that all pieces of the winding remain machine-manageable.
  • the winding shaft preferably has a clamping device.
  • the clamping device clamps the front end, that is to say the end that first reaches the winding shaft, on the winding shaft, so that the winding shaft can wind up the circumferential sleeve with a certain tensile stress.
  • the wrap can be kept very compact, which saves valuable storage space when disposing.
  • the clamping device can preferably be actuated pneumatically or hydraulically with the aid of a fluid. Such actuation is easy to control.
  • the clamping then takes place, for example, by introducing the fluid, while the loosening can take place by draining the fluid. In this way it can also be ensured that the clamping device clamps the end of the circumferential envelope to be gripped uniformly over the entire length, as a result of which a relatively uniformly wound winding can also be formed.
  • the clamping device preferably has a peripheral section of the winding shaft which can be pivoted about an axis running essentially parallel to the winding shaft axis, the peripheral section in the tensioned state of the winding shaft forming part of the surface of a circular cylinder, the axis of which coincides with that of the winding shaft. If the clamping device is tensioned, that is to say holds the circumferential sleeve, the outer circumference of the winding shaft forms a circular line in cross-section over most of the circumference. Of the The winding is then wound essentially circularly. There are no disruptive bulges.
  • the peripheral section is connected to an installation of the winding shaft via a tension spring device.
  • the tension spring device pulls the peripheral portion inwards in the relaxed state of the clamping device, so that the effective diameter of the winding shaft is reduced. Then the finished winding can be removed more easily from the winding shaft.
  • a clamping force can be defined via the tension spring device.
  • the clamping device preferably has a hose which is arranged between the installation and the peripheral section and which can be pressurized by the fluid.
  • the hose When the hose is pressurized, it clamps the end of the peripheral sleeve between itself and the peripheral portion. With the help of the hose, a uniform axial distribution of the clamping force can be achieved.
  • a stop is advantageously provided which limits an inward movement of the peripheral section before the hose has reached its smallest volume during relaxation. This ensures that when the hose is relaxed, both the clamped end of the circumferential sleeve is released and a reduction in the effective diameter of the winding shaft is achieved. The finished winding can then be easily removed from the winding shaft.
  • the transport device advantageously has at least one pull roller arrangement at its entrance a driven roller and a nip, at least one roller being movably mounted to open the nip.
  • the nip is opened as far as possible to accommodate the front end of the circumferential sleeve. In many cases, due to the rigidity of the circumferential envelope, this end is still bent upwards, which is caused by a so-called "curling effect". If the nip is now opened far enough, the front end of the circumferential sleeve can still be inserted into the nip without problems. Then the roller gap can be closed and the conveying begins.
  • a support roller arrangement is provided with at least one driven roller on which the roll to be unpacked rests, the driven rollers of the tension roller and support roller arrangement having essentially the same peripheral speed. If the carrier roller is now driven, the unpacked roller acts as a counter roller. The circumferential sleeve is then rewound or pushed between the roller and the driven support roller. It then enters the open nip of the draw roller assembly. The tension roller arrangement closes the roller gap and the transport of the circumferential envelope now takes place simultaneously through the tension roller and the support roller arrangement. Since both roller arrangements have essentially the same circumferential speed, there can be neither an unfavorable tension in the spread circumferential envelope nor a warping. The circumferential envelope is drawn evenly into the transport device.
  • a guide channel leading up to the winding shaft is preferably provided between the pulling roller arrangement and the winding shaft.
  • the transport device then comes along a single pair of pull rollers.
  • This pair of pull rollers pushes the circumferential sleeve through the guide channel, which of course must have a width corresponding to the width of the circumferential sleeve, up to the winding shaft.
  • the circumferential sleeve is guided so that it also reaches the winding shaft with great reliability.
  • the guide channel can be pivoted away from the winding shaft at least with its end adjacent to the winding shaft. On the one hand, this makes it possible to ensure that the end of the circumferential envelope is reliably brought up to the winding shaft. On the other hand, the guide channel no longer interferes with the manufacture of the roll. The winding can reach the required thickness without colliding with the guide channel. Instead of a pivoting movement, another, e.g. translational movement of the channel end may be possible.
  • the winding shaft can be locked in a receiving position in which the clamping device is opposite the end of the guide channel and in a dispensing position in which the stripping device can be inserted into the axially extending recess formed in the area of the clamping device.
  • the design of the clamping device can be used to simultaneously produce the axially extending recess.
  • the circular outer shape of the winding shaft is disturbed as little as possible. In principle, as an additional measure, you only have to ensure that the winding shaft can stop in the two positions and is held there.
  • Sensor elements are preferably provided in the area of the squeeze roller arrangement and / or the pull roller arrangement, which detect the presence of the circumferential envelope and which are connected to the control device, wherein the control device controls the opening of the nips of the squeezing or pulling roller arrangement and / or the drive of the respective rollers depending on the presence of the circumferential envelope. As soon as the circumferential envelope has entered the pulling roller arrangement, this is detected by the sensors, which for example form a light barrier. The nip of the pull roll assembly can then be closed so that the transport of the peripheral sleeve through the pull roll assembly begins.
  • the entry of the winding into the nip roller arrangement can also be detected, so that the nip of the nip roller arrangement can be closed.
  • the treatment of the circumferential envelope can be largely automated. It is only necessary to initiate the disposal process and to ensure that the circumferential sleeve enters the pull roller assembly.
  • the object is achieved in a method of the type mentioned in that a wrap is made from the circumferential envelope and the wrap is compressed transversely to its axis.
  • the folding of the envelope is divided into two steps. First, a wrap is made that is much more compact and therefore easier to handle than the flat, circumferential cover. Then the wrap is compressed so that it takes up less space. In the end it is also achieved that the circumferential envelope is folded onto one another in multiple layers.
  • Sections are preferably severed in the longitudinal direction from the compressed roll. These sections are correspondingly easier to handle. Your disposal is simplified. With smaller sections, the filling level of a collecting container can be increased.
  • the sections fall into a collection container after separation.
  • a device 1 for unpacking a roll of material web 2, 2 ′ has an unpacking station 3, a transport device 4 and a folding device 5.
  • the unpacking station has a pair of support rollers 6, 7 which can be lowered from the position shown in solid lines to the position shown in dashed lines.
  • the support roller 6 can be driven by a motor 8, which can be actuated by an operator 10 via a foot switch 9.
  • the transport device 4 has, behind a small ramp 11, a pair of pull rollers 12, 13, of which the lower pull roller 12 can be driven by means of a motor 14, while the upper pull roller 13 can be pivoted from the position shown in solid lines to the position shown in broken lines one between the Pull rollers 12, 13 formed nip 15 to open relatively wide.
  • the actuation of the motor 14 can also take place via the foot switch 9, so that the supporting roller 6 and the pull roller 12 are always driven simultaneously.
  • the actuation of the motors 8 and 14 can also take place from another location, for example on a control panel 24.
  • the motors 8 and 14 are matched to one another in such a way that the two rollers 6, 12 always have approximately the same peripheral speed.
  • a guide channel 16 is arranged, which is delimited by two plates 17, 18.
  • the guide channel 16 has a relatively large width, which in the extreme case is sufficient to also accommodate a circumferential envelope of the longest roll 2, 2 'to be unpacked.
  • the guide channel 16 leads up to directly in front of a winding shaft 19, which is described in more detail in connection with FIGS. 3 and 4. At least the part 20 of the guide channel 16 or its housing 18, which is adjacent to the winding shaft 19, can be pivoted away from the winding shaft 20, so that it is ensured on the one hand that a circumferential sleeve 21 guided through the guide channel 16 is guided safely to the winding shaft 19, but on the other hand that Manufacturing a winding with the help of the winding shaft 19 is not hindered, even if the winding should finally have several layers.
  • the winding shaft 19 is mounted on one side in a housing 22 and is provided with a drive 23 which can set the winding shaft 19 in rotary motion.
  • the control panel 24 is also provided on the housing 22.
  • the housing 22 also carries a scraper 25 which is movable in the direction of the double arrow 26 on a guide 27.

  • the squeeze roller 30 can be driven by means of a motor 53.
  • a sensor device consisting of two sensors 32, 33 is provided, which detects the entry of a roll into the opened nip 31.
  • the sensor arrangement 32, 33 can be designed, for example, as a light barrier.
  • a cutting device 34 On the side of the pinch roller arrangement 28 facing away from the winding shaft, a cutting device 34 is provided, which has a knife 35 and a feed table 36 and a knife drive 37.
  • a collecting container 52 Arranged below the cutting device 34 is a collecting container 52, one side wall 54 of which is arranged below the space between the squeeze roller arrangement 28 and the cutting device 34. Parts cut by the cutting device 34 then fall directly into the collecting container 52. Parts that are no longer gripped by the cutting device 34 but are transported by the nip roller arrangement 28 can still fall into the container 52.
