Definitions

  • the present invention relates to an attachment device for attaching valve sacks and in particular for attaching woven and / or sewn valve sacks onto a filler neck of a particularly rotating packaging machine.
  • Rotating packing machines with 4, 6, 8, 10, 12 or 16 or a different number of filling spouts have become known in the prior art. They are used for the effective filling of a wide variety of materials. For example, bulk goods such as cement are often filled using rotating packaging machines. Modern packing machines allow high filling rates, at which, for example, a sack or more is filled per second.
  • valve bags are pushed or shot onto the filling nozzle of the packing machine by an automatic device during the rotational movement.
  • the bags In order to achieve a high attachment rate, the bags have to be picked up in a defined manner and shot onto the filling spouts of the packing machine from a defined position.
  • valve bags made of paper When filling such bulk goods into valve bags made of paper, it is possible to work reliably with a high rate of attachment, since valve bags made of paper have a certain inherent rigidity.
  • valve sacks made of more flexible materials which for example consist of a fabric or a ribbon fabric made of plastic materials, then these valve sacks have a greater flexibility, which causes considerable difficulties in the automatic attachment.
  • valve bags made of fabric or ribbon fabric are shot onto the rotating filler neck of a packing machine.
  • the known device uses a tab-like area in certain valve sacks, which is created when sewing around and protrudes from the sack surface in order to blow a targeted blast of air underneath, with which the valve sack is positioned at an upper stop in a defined manner.
  • the known device works reliably and enables high attachment rates and high attachment rates, provided that a sufficient flap is formed on the valve bag, on which the blast of air can attack.
  • a sufficient flap is formed on the valve bag, on which the blast of air can attack.
  • reliable attachment only works at relatively low speeds or attachment rates.
  • the contact surface for the blast of air is not sufficient to quickly align the valve bag upwards.
  • Such a plug-on device does not work economically at low speeds.
  • An attachment device is used to attach valve sacks and, in particular, to attach woven and / or sewn (flexible) valve sacks onto a filler neck of a packing machine.
  • the attachment device comprises a gripper holder which can be moved between a receiving position and an alignment position and has at least one gripper in order to grip a valve bag in the receiving position.
  • the attachment device further comprises a blowing device with at least one air nozzle in order to align the valve bag in the alignment position (defined).
  • a receiving space for a sack section of the valve sack is formed between the gripper holder and the blowing device, at least in the alignment position of the gripper holder Receiving space aligned in order to act on opposite side walls of a valve sack received in the receiving space, and wherein a contact device with an upper stop delimits the receiving space and a valve sack can be aligned in a defined manner thereon.
  • the attachment device has many advantages.
  • a significant advantage of the invention The slip-on device consists in that the blower device with the air nozzle or air nozzles acts on the valve bag to be aligned from a side opposite the grippers. It has surprisingly been found that an effective attachment is possible with this. Surprisingly, it is not necessary to blow from below against a tab on the valve of the valve sack in order to thereby transport the valve sack upwards. The tab may not exist at all or hardly at all. The air blast occurs in particular from the side opposite the tab, so that the tab cannot contribute to the advance, if a tab is present at all.
  • the invention forms an air cushion on the side opposite the gripper, which also reduces any friction between the valve bag and any walls.
  • the valve sack with the gripper is picked up from a stack of sacks (e.g. lying horizontally on a table) and brought into a raised position. If air is directed in the direction of the valve bag only from the side opposite the gripper, the valve bag can slide on an air cushion and be aligned. In this case, the valve sack can also (at least partially) be transported in the vertical direction by the directed air flow due to the often very rough surface of woven and / or sewn valve sacks in order to be aligned.
  • a receiving space for a sack section of the valve sack is formed between the gripper holder and the blowing device, the gripper acting on a first side wall and in particular an upper side wall and the air nozzle acting on an opposite, second and in particular lower side wall of the valve sack.
  • the gripper picked up the uppermost valve sack of a stack of sacks on a pick-up table or, for example, received it via another gripper.
  • the gripper can grip the valve bag in particular in the valve area.
  • an abutment device with an upper stop limits the receiving space at the top.
  • a valve bag can be aligned in a defined manner on the upper stop.
  • the upper stop is preferably V-shaped.
  • an acute-angled area is formed on the V-shaped stop. This ensures a defined positioning of a valve bag on the upper stop.
  • the contact device comprises an angle plate.
  • the upper stop can be formed on the angle plate.
  • the upper stop can be formed by the angle plate.
  • the angle plate is designed in particular V-shaped and is open towards the receiving space, so that a defined alignment of a valve bag and in particular the valve area on the upper stop is made possible.
  • the gripper holder is preferably coupled to the blowing device. It is particularly preferred that the gripper holder can be moved relative to the blowing device.
  • the gripper holder and the blowing device are preferably pivotably coupled to one another. In this case, pivoting in opposite directions is possible, which, depending on the pivoting direction, leads to an enlargement or reduction of the recording space.
  • air openings are formed on the contact device and in particular on the angle plate. Some air openings are particularly preferably formed in the corner or in the vicinity of the corner or in the acute-angled area of the upper stop. The air openings allow air to escape from the receiving space through the air openings into the environment. This enables the air flow to be diverted from the air nozzles and thus a directed flow without congestion, which makes it easier to position the valve bag.
  • the gripper holder is preferably received pivotably on a gripper holder coupling.
  • the gripper holder coupling is movable in order to transfer the gripper holder from the receiving position into the alignment position.
  • the major part of the path of the gripper holder from the receiving position into the alignment position is particularly preferably achieved by moving the gripper holder coupling.
  • a not insignificant movement of the gripper holder can be carried out in order to reach the alignment position.
  • a drive device can be provided which is provided for pivoting the gripper holder and / or the blowing device.
  • the drive device is preferably formed by or comprises a cylinder drive.
  • the drive device is preferably coupled to the gripper holder coupling and to a swivel arm of the gripper holder.
  • a pivoting of the gripper holder on the gripper holder coupling is achieved. This preferably changes the angular orientation of the gripper holder relative to the gripper holder coupling.
  • the contact device and in particular the angle plate are preferably pivotably coupled to the gripper holder and can preferably be driven in a synchronized manner by means of the same drive.
  • the gripper holder is pivotably received on the gripper holder coupling or is pivotably coupled to it.
  • the gripper holder coupling is preferably pivotable between a lower receiving position and an upper transfer position. An additional pivoting of the gripper holder is achieved in particular by the drive device, which aligns the gripper or grippers and the air nozzle or air nozzles in accordance with the valve bag to be positioned.
  • a transport device for transporting an (aligned) valve bag which comprises at least one belt strip and / or at least one roller strip.
  • the transport device is preferably used to accelerate the valve bag, which is aligned (in the vertical direction), in the direction of the filler neck and finally to open it.
  • the bag valve can be opened during the acceleration.
  • the air nozzle is at least partially oriented in the direction of the V-shaped opening of the upper stop. An air flow is then achieved at least also in the direction of the upper stop, as a result of which more reliable positioning is achieved.
  • the blowing device preferably comprises a pipe with several air nozzles and is attached directly or indirectly to the angle plate.
  • a plurality of through openings are particularly preferably formed between the tube and the angle plate.
  • the attachment of the blower to the angle plate can take place via several (narrow) webs.
  • At least one additional nozzle which is oriented from a first side in the direction of the receiving space.
  • the additional nozzle acts on the first side surface of the valve bag.
  • a seam and / or a tab and / or a bag protrusion is provided on the first side surface of the valve bag.
  • the additional nozzle preferably blows under the tab on the first side surface of the valve bag.
  • the additional nozzle offers considerable advantages, since it can further improve the positioning quality and thus the attachment rate and the attachment rate.
  • the additional nozzle largely corresponds to the nozzle known from the prior art, with which, however, a sufficiently satisfactory result could not be achieved alone with difficult bag material and insufficient bag protrusions.
  • the reliability of the attachment is increased even further.
  • the sack section is enveloped with a directed air flow both from below and from above (on both sides).
  • the sack section, on which the air nozzle and the additional nozzle act for a defined alignment is aligned obliquely to the vertical.
  • the gripper is preferably aligned at an angle between about 30 ° and 80 ° and in particular between about 30 ° and 70 ° and preferably at about 50 ° +/- 15 ° to the horizontal.
  • the additional nozzle blows preferably on the wall arranged further up (upper wall or first side surface) and the air nozzle on the wall arranged further down (lower wall or second side surface) of the valve bag.
  • the method according to the invention is used to attach valve sacks and, in particular, to attach woven and / or sewn valve sacks (for example made of woven fabric) onto a filler neck of a particularly rotating packaging machine, with a valve sack being gripped with a gripper in a pick-up position and the valve sack with in an alignment position a blast of air from an air nozzle (defined).
  • the gripper grips the valve sack on a first side wall and the air nozzle acts on the opposite, second side wall, around the valve sack in an at least partially vertical direction Direction to align defined on an upper stop of a contact device.
  • the method according to the invention also has many advantages.
  • the method makes it possible to reliably and automatically attach valve sacks with a sack valve and two opposing side surfaces or side walls, even if the valve sacks have no or very short folded flaps and are made of flexible ribbon fabric.
  • the gripper preferably grips the upper side wall of a valve sack lying on a sack stack in order to then align it in a defined manner.
  • the air nozzle is at least partially aligned upwards and blows from below against the second side wall of the valve bag.
  • the gripper is released and the valve bag is freely guided in the air flow. This ensures that the valve bag is transported to the upper stop.
  • the force required for transport is applied to the rough side wall of the valve bag by the blast of air.
  • the air nozzle preferably blows from below against the sack wall located at an angle in the room and forms an air cushion between the wall of the valve sack and the angle plate, which reduces friction and ensures reliable transport to the upper stop.
  • the air nozzle is advantageously operated with an air stream at a higher level until a sensor detects the valve bag at an upper stop. Then the air flow can be reduced to a lower level or switched off. A reduction to a lower level prevents creases from forming in the upper area of the valve bag.
  • At least one additional nozzle and in particular several additional nozzles direct an air flow onto the upper side wall when the valve bag is to be aligned.
  • the additional nozzle sends preferably an air stream when the air nozzle and the gripper holder have been pivoted at least a little towards each other.
  • the air nozzle and the gripper holder are swiveled towards each other after a sack has been gripped and lifted.
  • the air flow from the additional nozzle can be reduced or, if necessary, switched off when a sensor detects the valve bag at the upper stop.
  • targeted blowing with the aid of the additional nozzle can support the release of the valve bag from the grippers.
  • one gripper or all grippers are designed as suction cups.
  • the suction cups are designed as suction cups.
  • the blowing device with the air nozzle or air nozzles is first activated in order to align the valve bag.
  • a folded end of a valve bag can be brought back into the appropriate and correct position.
  • the teat then lets go of the valve bag, for example by switching off the negative pressure on the teat.
  • the additional nozzle can then be activated in addition to the air nozzle, so that a particularly reliable transfer of the valve sack to the upper stop is ensured and the release of the sack is supported by the suckers if necessary.
  • the lower side wall of the valve bag slides obliquely upwards on the air cushion of the air nozzle until the valve bag rests against the upper stop.
  • the air supply can then be switched off at the air nozzle and reduced at the additional nozzle. This can save energy.
  • folds of flexible bags against the upper stop are reliably prevented. This positioning is maintained until the roller and belt strips are closed and the previously aligned valve bag accelerates towards the filling machine.
  • Figure 1 shows a strong Schematic top view of a packing system which comprises a rotating packing machine 101, an attachment device 1 and a discharge belt 120.
  • the packing machine 100 for filling valve sacks 10 has six filling nozzles 101 arranged distributed over the circumference, of which valve sacks 10 are each arranged on five filling nozzles 101.
  • the packing machine 100 is in the attachment position.
  • the angle sensor 102 has previously detected the rotating past of the next filling nozzle 101 in the predetermined angular position 103 and thus triggered the next attachment process.
