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, having a frame and a strapping unit which has a guiding device which guides the strapping means around a package and a below the conveyor track in the Clasping plane arranged, which connects the loop ends of the strapping means together (z. B. GB-A-1 120 778).
  • 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.
  • 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, then the closing device is a knotting unit which knots the ends of the loop around the package. If wire is used for the strapping, the closing device can be a twisting device which twists or ties together the ends of the wire loop which is guided around the package.
  • 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 object of the invention is to provide a strapping machine in which it is not necessary to stop the packages for making the strapping.
  • the strapping unit in the conveying direction of the packages can be pushed back and forth in the frame and driven by a fixed to the frame, effective in both directions drive and that on both sides of the strapping level on the strapping unit at the level of the conveyor conveyor are arranged, which take over the packages to be strapped from the feeding conveyor belt and, after moving the strapping unit in the conveying direction, deliver the strapped package to the outgoing conveyor 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 delivered 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 guiding device, the closing device and the conveying means are attached to a slide-like frame which is slidably mounted on a straight guide mounted in the frame.
  • the funding on the sliding strapping unit can be rollers that are provided with a backstop. 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 carried 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.
  • the conveying means of the strapping unit are formed by at least one endless conveyor belt which is aligned with the feeding conveyor belt via an infeed roller mounted on the frame and a first deflecting roller arranged on the strapping unit in front of the strapping level, then down around the closing device of the
  • the strapping unit is guided around 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 mounted on the strapping unit and in the flight of the conveyor via a run-off roller mounted on the frame and the empty run of the conveyor belt over at least a return roller mounted on the frame below the strapping unit is returned to the feed roller.
  • FIG. 1 and 2 show, 1 packages 2, z. B. stack of newspapers or the like of a strapping machine 3 and the strapped packages 2 'transported by a conveying belt 4.
  • the strapping machine 3 is composed of a frame 5 and a strapping unit 6 mounted therein in the direction of conveyance of the packages 2 and can be pushed back and forth with a guiding device 8 which guides the strapping means 7 around the package 2 and a visible from FIG. 3, the two ends of the Package 2 wrapping loop of the strapping means connecting fastening device 9.
  • the closing device is a welding unit. If cord or the like is used as the tying 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, which take over the packages 2 to be strapped from the feeding conveyor belt 1 and, after shifting the strapping unit 6 in the conveying direction, delivers the strapped package 2 to the conveying conveyor belt 3.
  • 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, a second upper deflecting roller 16, and a second reversing roller 17 via an infeed roller 11 , a run-off roller 18, a first return roller 19 and a second return roller 20 are guided such that the package 2 'located in the strapping position is carried on both sides of the strapping plane by the conveyor belt 30, 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 discharge roller 18 is designed 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 is slidably mounted on a straight guide mounted in the frame 5, which is composed of two guide rods 27 fastened in the frame 26.
  • a pneumatic or hydraulic piston-cylinder unit 28 arranged parallel to the guide rods 27 in the frame 5, the piston rod 29 of which engages the frame 26, causes the strapping unit 6 to be pushed back and forth.
  • a motor-driven spindle drive can also 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 by the feeding conveyor belt 1 without delay or acceleration, transported further and strapped in the process, and the strapped package 2 is delivered to the discharging conveyor belt 4. Because during the movement of the strapping unit 6 or the frame 26 in the conveying direction the strapping unit 6 and the conveyor belt 30 have essentially the same speed, the conveyor belt 30 is stationary relative to the strapping unit 6, so that the strapping can be carried out despite the conveyor belt 30 continuing to run.
  • the guide device 8 has a guide frame which frames a rectangular passage 31 for the packages 2. Below the support level of the package 2 there is a trigger and shoot-in device 32 for the strapping means 7 in the strapping unit.
  • the guide frame has a guideway on the inner surface facing the package.
  • the strapping band 7 is shot into this guideway by means of the pull-off and shooting device, so that the beginning of the strapping means 7 is guided around the package 2 and the strapping means 7 forms a loop looping around the package 2, which is drawn in while holding the beginning of the band and then under Voltage is closed.
  • the closing and severing device 9 With the help of 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 shot.
  • the driving belt 33 is an endless flat belt which is guided over guide rollers 34 and a drive pulley 35.
  • a rotatable ring US Pat. No. 2,339,395 can also be used in a known manner.
  • the reversing rollers 12 and 17 are at a greater distance from the constriction plane than the reversing rollers 12 'and 17' of the side guide belts 30 'because the closing and severing device 9 is accommodated between them.
  • the reversing rollers 12 'and 17' of the side conveyor belts 30 ' are arranged so close together that only a gap remains between them through which the strapping means 7 can be moved.
  • the lateral guide belts 30 ' have the advantage that the package 2 is well supported even in the surrounding position.
  • the middle guide band 30 has the advantage that soft and sagging material, e.g. B. newspapers, well supported in the middle.
  • newspaper stacks can be conveyed at a conveying speed of 0.3 m / sec and at intervals of approximately 0.3 m and thereby tied up.
  • the travel path or displacement path of the strapping unit 6 is approximately 0.3 m. While the displacement speed of the strapping unit 6 in the conveying direction is approximately 0.3 m / sec, the return speed is approximately 0.5 m / sec.
  • the conveyor speeds can be increased considerably and the distances between the packages 2 to be strapped can be shortened accordingly.
  • the packages 2 to be strapped can already be picked up by the conveyor belt 30, 30 'of the strapping machine, while the preceding package 2 is still in the strapping position or is being delivered to the removing conveyor belt 4.
  • the strapping process is triggered by a push button or by a photocell.
  • FIG. 6 shows an exemplary embodiment in which all the conveying means of the strapping unit are rollers 40, which run freely in the conveying direction and which are provided with backstops.
  • the feeding conveyor belt 1 pushes the packages 2 to be strapped into the strapping position.
  • the strapping process and the displacement of the strapping unit 6 in the conveying direction are then triggered by a pushbutton switch or a selenium cell or the like.
  • the strapped package 2 rolls due to the inertia forces on the conveying belt.
  • FIG. 7 shows a guide of the conveyor belt 30, in which fewer deflection rollers are used than in the embodiment according to FIGS. 1, 2 and 4.
