Definitions

  • the invention relates to a strapping machine which is to be arranged between a conveyor belt feeding the packages to be strapped and a conveyor belt removing the strapped packages, with a frame and a strapping unit which guides the strapping means around a package Rungs device and a below the conveyor track in the tying level, the loop ends of the tying means interconnecting closing device.
  • Strapping machines of this type are known and they serve, in particular, to strap up newspaper or illustrated stacks. However, other packages can also be tied using plastic tape, cord or wire. If plastic strapping is used for the strapping, the closing device of the strapping unit is a welding device, with the aid of which the ends of the loop which is guided around the package are welded to one another. If cord is used for the tying, the closing device is a knotting unit which knots the ends of the loop around the package.
  • the closing device can be a twisting device which twists or ties together the ends of the wire loops guided around the package. If a steel band is used for the strapping, the closing device is an embossing device which connects the ends of the steel band loop which is guided around the package by plastic deformation and, if appropriate, with the aid of a sheet metal locking clip.
  • the packages which had been fed from a conveyor belt had to be stopped, brought into the lacing position and, after the lacing, pushed back onto a conveying conveyor belt.
  • the braking of the packages, the strapping of the packages and the acceleration of the packages cause considerable delays in the conveyance of the packages.
  • the conveyor belts can only convey as many packages per unit of time as the strapping machine is capable of strapping per unit of time. As a result, the distances between the packages on the conveyor belt to be fed must be relatively large.
  • the object of the invention is to provide a strapping machine in which it is not necessary to stop the packages to make the strapping.
  • the strapping unit can be pushed back and forth in the conveying direction of the pack pieces in the frame and can be driven by a drive which is fastened to the frame and is effective in both directions, and in that on both sides of the strapping level on the strapping unit in height Conveying means are arranged on the conveyor track, which take over the packages to be strapped from the feeding conveyor belt and after moving the strapping
  • OMPI delivery unit in the conveying direction, deliver the tied package to the conveying belt.
  • the packages can be fed to the strapping machine in closer succession.
  • the strapping unit is moved in the conveying direction at approximately the conveying speed of the feeding conveyor belt, and the strapping is carried out at the same time.
  • the strapped package is released to the conveying conveyor belt and the strapping unit is pushed back to the feeding conveyor belt so that the next package can be picked up and strapped.
  • the strapping unit with the guide device, the closing device and the conveying means are attached to a slide-like frame, which is displaceably mounted on a straight guide mounted in the frame.
  • the funding on the sliding strapping unit can be roles that with a
  • These rollers can be freely rotating, so that the packages are pushed onto the freely rotating rollers of the strapping unit by the feeding carrier tape.
  • the strapping position of the packages on the strapping unit can be determined by a stop. Since the rollers are provided with a backstop, the package is taken along by the strapping unit moving in the conveying direction and strapped in the process. If the strapping unit is suddenly braked at the end of the displacement path, the strapped package lying on the rollers rotating freely in the conveying direction can continue to move in the conveying direction due to its inertia until it is taken over by the conveying conveyor belt. But it is also possible to drive the funding of the umm lacing unit.
  • rollers If these conveying means are rollers, the drive of these rollers must be controlled so that the drive is interrupted as soon as the package is in the strapping position. As soon as the strapping unit is in the vicinity of the discharge conveyor belt, the rollers can be driven again so that the strapped package can be delivered to the discharge conveyor belt.
  • the conveying means of the strapping unit are formed by at least one endless conveyor belt which, in the flight of the feeding conveyor belt, is arranged via an infeed roller mounted on the frame and a strapping unit in front of the strapping level, first downward pulley around the closing device of the strapping unit via at least one deflection roller mounted on the strapping unit, then upwards via a second reversing roller arranged in the flight of the conveyor behind the strapping plane and a strapping unit and in flight of the conveyor track via one Discharge roller mounted on the frame is guided and the empty run of the conveyor belt is returned to the feed roller via at least one return roller mounted on the frame below the strapping unit.

  • OMPI Fig. 2 is a side view of the strapping machine. In a position after strapping the package
  • Fig. 3 is a cross-sectional view.
  • Fig. 4 is a longitudinal sectional view and Fig. 5 is a plan view of the strapping machine
  • FIGS. 1 and 2 show, 1 packages 2, e.g. Stack of newspapers or the like is fed to a strapping machine 3 and the strapped packages 2 'are transported further by a conveying conveyor belt 4.
  • the strapping machine 3 is composed of a frame 5 and a strapping unit 6 mounted therein, which can be pushed back and forth in the conveying direction of the packages 2, with a guide device 8 and a guide device 8 which guides the strapping means 7 around the package 2 and one 3 shows the locking device 9 connecting the two ends of the loop of the strapping means which wraps around the package 2.
  • 'tying means uses a sealable plastic tape, then the Sch.vorrich- is processing a welding unit. If cord or the like is used as the strapping means, the closing device is a knotting unit. If wire is used as the strapping means, the closing device is a twisting device which twists the ends of the wire loop together.
  • the guide device 8 and the closing device 9 are located in the strapping plane. On both sides of the strapping level at the level of the conveyor track 6 conveying means 10 are arranged on the displaceable strapping unit, before the packages 2 to be strapped from the feeder
  • the conveying means 10 is a conveyor belt 30, which has a first reversing roller 12, a first upper deflecting roller 13, a first lower deflecting roller 14, a second lower deflecting roller 15, and a second upper deflecting roller via an infeed roller 11 16, a second reversing roller 17, a Abiauf ⁇ roller 18, a first return roller 19 and a second return roller 20 is guided so that the package 2 1 in the tying position is carried by the conveyor belt 30 on both sides of the tying level, but a gap 21 remains free between the two reversing rollers 12 and 17, through which the strapping means 7 is moved and brought into contact with the closing device 9.
  • One of the rollers 11 to 20 is designed as a drive roller.
  • tensioning and guide rollers 22 and 23 can also be provided.
  • the Abga ⁇ formed berolle 18 as a 'drive roller.
  • the roller 18 is driven via a chain 24 by an electric motor 25 attached to the frame 5 at a speed which corresponds to the conveying speed of the two conveyor belts 1 and 4.
  • the rollers 12 to 17 are mounted on a frame 26 which carries the strapping unit 6 with the guide device 8 and the closing device 9 and which can be moved on a straight guide fitted in the frame 5 is mounted, which is composed of two guide rods 27 fastened in the frame 26.
  • a piston-cylinder unit 28 one can also motor-driven spindle drive can be used.
  • the drive 28 moves the strapping unit in the conveying direction at a speed which corresponds to the conveying speed of the conveyor belts 1 and 4.
  • the conveyor belt 30 of the strapping unit 6 is also driven at the speed which corresponds to the conveyor speed of the conveyor belts 1 and 4. This has the effect that the packages 2 are taken over without delay or acceleration from the conveyor belt 1 to be conveyed, transported further and strapped in the process, and the strapped package 2 is delivered to the conveyor belt 4 being removed. Because the strapping unit 6 and the conveyor belt 30 have essentially the same speed when the strapping unit 6 or the frame 26 moves in the conveying direction, the conveyor belt 30 stands still relative to the strapping unit 6, so that despite the conveyor belt 30 continuing to run the strapping can be done. As FIG. 3 in particular shows, a plastic band is used as the strapping means 7, the loop ends of which are welded or heat-sealed by the closing device 9.
  • the closing device 9 is also provided with a separating device which separates the band loop placed around the package 2 from the band supply.
  • the guide device 8 has a guide frame which frames a rectangular passage 31 for the packages 2. Below the support level of package 2 there is a
  • OMPI aggregate a trigger and shooting device 32 for the strapping means 7.
  • the guide frame On the inner surface facing the package, the guide frame has a guide track.
  • the strapping band 7 is shot into this guideway by means of the pulling-off and shooting-in device, so that the beginning of the strapping means 7 is guided around the package 2 and the strapping means 7 forms a loop which wraps around the package 2 and which forms under Holding the beginning of the tape closed and then closed under tension.
  • the closing and severing device 9 the beginning of the band is connected to the end of the loop, in particular welded, and the loop thus closed is separated from the band supply.
  • the guideway is formed by a driving belt 33, the conveying speed of which is equal to or greater than the speed at which the strapping means 7 is inserted.
  • the driving belt 33 is an endless flat belt which is guided over guide rollers 34 and a drive pulley 35.
