Definitions

  • the invention relates to a packaging machine according to the preamble of claim 1 and a method for packaging objects, in particular in a film tube.
  • Packaging machines are known, with which objects are packed in a film tube.
  • a closure device used for closing and severing the film tube has an upper punch above the film tube and a lower punch below it. These are simultaneously moved in opposite directions to one another in order to weld and cut through the film tube in one step. Since the articles are usually brought on a feed belt and discharged on a separate discharge belt, a band gap between the two belts is required on the closure device, so that the two punches can meet through them.
  • the invention has for its object an initially mentioned packaging machine and a method to create, with which problems of the prior art can be avoided and in particular a fast and reliable packaging of objects is possible.
  • a band gap adjustment is provided for opening and closing the band gap.
  • a mechanical positive coupling is provided between the punches and the bandgap adjustment on the one hand such that when moving the upper punch and lower punch each other to the band gap is further opened by the positive coupling after the stamp have set to each other in motion and just before they meet.
  • the mechanical forced coupling is such that the band gap moves back through the positive coupling or closes when the stamps move away from each other.
  • the inventive opening of the band gap in positive coupling with the vertical movement of upper punch and lower punch to each other is achieved that the steps are always coordinated.
  • the mechanical positive coupling is very advantageous and very important. Although it could in principle also be carried out with separately driven and tuned by electronic control functional units or drives. However, this has proven in practice to be too expensive or not sufficiently accurate. Furthermore, a mechanical forced coupling is much less prone to failure than an electronic solution, it also eliminates the need for the vote sensor.
  • the band gap adjustment on each of the band gap facing end roll of the feed belt and an end roller of the discharge belt can be displaced along the longitudinal direction of the bands, preferably at least in opposite directions for opening and closing the band gap.
  • only one end roll of a band can be moved for opening and closing the band gap, advantageously the discharge belt. This therefore means that the bands per se or their respective deflection and drive rollers remain essentially unchanged, in particular also the beginning of the feed belt and the end of the discharge belt. Only at least one of the band gap facing end rollers is moved, which changes their effective tape length and the width of the band gap.
  • rotatable end rollers and rigidly arranged knife edges can be provided as round or rounded end edges around which the band rotates. Above all, they can be used together with correspondingly suitable textile tapes, which overall reduces the design effort.
  • a compensation device is provided on each of the belts, with which the belt tension is maintained during movement of said end rollers, wherein in particular the compensation devices are of similar construction.
  • these balancing devices can absorb some tape length in the discharge belt, including, for example, a known S-like or similar multiple looped leadership of the band can be provided. So they allow almost a shortening of the top of the feed belt.
  • the conveyor belt length is added by the compensating device, so that the tape length of the top can extend. This is especially advantageous in the welding systems explained in more detail below.
  • the aforesaid balancing means are coupled directly to each other for fixed adjustment of the bandgap, this adjustment of the bandgap being independent of the opening or closing of the bandgap.
  • this coupling is adjustable in length for an extension or shortening of the band gap, which remains the same even with horizontal movement of the closure device.
  • the mechanical positive coupling according to the invention can be achieved by providing a driver driven by the closure device or by one of the punches, in particular vertically movable, which runs in a slot or curve-shaped groove.
  • the driver is advantageous a roller, so that friction can be minimized.
  • the backdrop advantageously has two areas with a vertical course, which are slightly offset from each other and are connected to each other by means of a bevel or an oblique oblique area. This results in a backdrop in the manner of an S-curve, but with a rather small curvature.
  • the transition of the vertical regions in the oblique region is advantageously rounded. Thus, reasonably gentle movements or no too jerky movements and accelerations, which would mean unnecessary mechanical stress.
  • an oblique region can have an angle of 30 ° to 60 ° to the vertical direction, particularly advantageously an angle of 40 ° to 50 °. This results in approximately uniform loads at the two transitions to the vertical areas.
  • An offset in the backdrop between the two vertical areas or their distance may correspond to the width of the backdrop in itself, but also be wider. This means that the offset is clearly present but not too large.
  • the offset of the two vertical areas of the backdrop to each other also defines the distance by which the bandgap is extended or extended. Thus, if the offset or distance is, for example, four centimeters, then the band gap is also opened four centimeters when the punches move together. The aforementioned transition from the oblique region to the vertical regions with its rounding determines acceleration and deceleration of the displacement device.
  • the positive coupling is formed so that over a certain range of movement of upper punch and lower punch on the closure device, so when moving in a vertical direction toward each other, yet no opening of the band gap occurs.
  • This can take into account the fact that upper punch and lower punch have a certain distance from each other through which the objects to be packaged must fit.
  • the two punches can continue to drive towards each other or a whole piece to drive towards each other before they hit the film tube. Therefore, no direct opening of the band gap is necessary here.
  • This opening is advantageous only when the driver reaches an activation area in the backdrop.
  • This activation area is advantageously the said oblique area in the backdrop.
  • the activation area or the oblique area in the backdrop is formed so that only shortly before the meeting of lower punch on the lower side of the belt driven by one of the punch driver reaches the activation area.
  • This can be advantageous one centimeter to four inches. Runs the driver then into the activation area or oblique area, so the slope forces in addition to the ongoing vertical movement in addition a horizontal movement, so moving along the backdrop, and this in turn a movement of the end roller, for example, the discharge conveyor. This has the consequence that the band gap opens for the lower stamp.
  • the link is mounted horizontally movable, advantageously in a link plate, and the driver in its vertical movement through the inclined region while the horizontally movably mounted link plate and coupled thereto Endrollenver ein or bandgap adjustment in desired degree moved.
  • the driver is advantageously arranged vertically movable on the closure device, in particular directly connected to the lower punch for a common and same vertical movement.
  • the closure device is movable along the transport direction of the objects for closing the film tube in continuously running objects synchronously with their movement.
  • the band gap is moved without changing its width, at least for a short way to accelerate or Aufsynchronify on the objects to be packaged.
  • the closure device is arranged on a horizontally movable carriage, wherein preferably at least one of the aforementioned compensation devices is connected or coupled with the carriage for a movement in the same direction. Simultaneously with the closure device and the band gap is moved or moved, for the time being without mandatory opening.
  • the closure device is thus brought to the speed of the film tube for a short time and runs with it for a short distance so that there is no movement relative to one another. Therefore, the two stamps can easily weld the foil tube or seal and cut. For this, in practice, a distance of a few centimeters, for example five centimeters to a hundred centimeters or even only ten centimeters to forty centimeters.
  • the balancing devices on the bands for the movement of the band gap are advantageously connected to the closure device or to a horizontally movable carriage on which the closure device is mounted.
  • the compensation devices can either be coupled to this slide or the closure device, or else directly to one another.
  • the horizontal movement imposed by the closure device or the driver is also transferred from one equalizing device to the other.
  • the band gap can be kept to a desired level or, depending on the objects to be packaged or the formation of the closure device, be adjusted to a fixed value.
  • the upper punch and lower punch are connected by means of arms with a release lever at opposite areas, so that the pivot point of the release lever is located therebetween.
  • a trigger lever can also a disc or the like. be provided.
  • the stamp By driving the release lever, the stamp can be moved synchronously or raised and lowered.
  • no dead band is provided therebetween, so that the pistons move at all movement of the release lever and also move accordingly.
  • the release lever itself can in turn be driven by a drive either via a lever or a joint rod or be provided directly with a rotary drive.
  • this is known per se from the prior art.
  • the distance between the upper punch and lower punch to each other or to the band gap is adjustable on the closure device.

  • the articles 13 are already packed in individual film bags 15, which are produced by separating the film tube 14.
  • Such packaging machines are basically known, see for example the DE 203 04 333 U1 ,
  • the articles 13 come from the right on the feed belt 17, which has an end roller 18 to the left and at the right end of an inlet roller 19.

  • a band gap 23 is formed between the right end roller 18 and the left end roller 21, a band gap 23 is formed. This can in practice a few millimeters to one Centimeters or a maximum of four centimeters. It should be as small as possible, so that short objects or those with unfavorably distributed center of gravity do not fall into the band gap 23 or slide in during transport and in particular during the transition from the feed belt 17 to the discharge belt 20.

  • the temporal progression of the method according to the invention on the basis of Fig. 4 starting from Fig. 2 means that with the onset of rotation of the release lever 41 and upwardly running lower punch 36, the roller 44 pushes the link plate 46 to the left to open the band gap 23. If the roller 44 moves in the upper straight portion 50, similar to the lower straight portion 48, outside the sloping area 49, so there is only a vertical process of the lower punch without the link plate 46 to move and thus to change the band gap 23. This is important above all in the upper straight region 50, which is why it has a very long design, so that the abutment 37 can retract into the then-opened band gap 23 and reach through it.
