Definitions

  • the invention relates to a strapping device according to the preamble of claim 1.
  • the band guide channel extends along a spatial path, which is equivalent to the fact that in some of the path curves the band plane at the curve exit is angled relative to the band plane at the curve entry, while in another part of the curves the band is practically in the same plane runs in and out.
  • a strapping device of this type is described, for example, in the earlier European patent application 92 119 169.8. Then the tape turns in just before the rewind the clamping head, for example, a left turn. It is stated that the band guide channel in the curve - as one cannot generally imagine - is inclined transversely to the direction of the band.
  • the invention has for its object to avoid such a forced inclination of the tape by means of a correspondingly shaped tape guide channel and still let the tape run in and out in the same plane even with relatively tight curves.
  • this object is achieved according to the invention by an "active curve" which has the characterizing features of claim 1.
  • the band guide channel in the curve area is replaced by the circumferential groove of a rotatably mounted and preferably driven roller, the bearing axis of which is the curve axis.
  • the tape is inserted tangentially into the groove and ends tangentially again after the desired curve.
  • the band forms waves from sections twisted to the right and left, the extent of the torsion to the left and right being different depending on the curve. As a result of this wave formation, the band with the wave tips presses against the groove side walls.
  • the roller is formed from sheet metal and has a rim whose cross-section corresponds to that of the desired circumferential groove and which is connected to a hub via a light wheel disc or spokes.
  • the circumferential groove have a trapezoidal cross section at the bottom of the groove and be at least as deep as the width of the band. It has already been mentioned that the band spreads due to the wave formation in the groove. Since the groove side walls are at an angle to one another, the band is displaced radially inwards, i. H. it rests on the groove bottom and does not tend to jump out of the circumferential groove as long as the band is only held in the circumferential groove at the ends of the groove arch. This is done through the inlet and outlet sections of the belt channel. The tendency of the tape to crawl inwards has the favorable effect that, apart from the beginning of the tape, the tape does not touch the cover sheet and therefore no sliding friction occurs as the tape passes.
  • the belt guide channel sections are connected tangentially at the inlet and outlet of the belt guide channel curve. Particular attention must be paid to the inlet side. If, which is to be regarded as advantageous, the groove is somewhat deeper than the band, then the inlet section is best arranged and dimensioned in such a cross-section that the band first enters the groove with the groove bottom and then only with the cover sheet in Touch comes. The beginning of the band is pushed away a little from the bottom of the groove and thus experiences an initial torsion, which periodically changes its direction in the following until the band runs out of the circumferential groove again, after which the elastic wave deformation is lost again.
  • the band guide channel is opened on at least one side so that the loop can emerge and be tensioned.
  • the opening of the tape guide channel can take place in such a way that the roller and the inlet and outlet channels are guided so as to be movable in the curve plane relative to the cover sheet and to the wall sections of these channels located on the outside of the curve, preferably approximately in the direction of the bisector the curve.
  • the movable parts of the inlet and outlet channel and the roller together with the bearing and drive or the cover sheet can be arranged on a common movable frame or holding plate, which can be moved back and forth with the aid of lifting cylinders or in some other way. If there is a left-hand and a right-hand curve with a deflection roller in one plane for the respective band guide channel, one becomes the roller in one curve and the other in the other Curve must make the cover sheet and the respective band guide frame parts movable.
  • the roller can be tilted or axially movable into an inclined position or that the roller is formed in two parts, a radial parting plane which penetrates the circumferential groove, an upper and separates the lower part of the roller.
  • the groove can be widened as desired by lifting the upper roller part relative to the lower part, so that the belt can easily pop out.
  • the role can also be inclined to the curve plane or to the inlet and outlet plane of the belt, ie with this plane inclined bearing axis, can be arranged.
  • the circumferential groove can have the same cross-sectional shape.
  • the storage and drive of which is not shown, has a continuous circumferential groove 2 with a trapezoidal cross section which widens inwards.
  • the cylindrical outer surface of the roller 1 is covered over an angle of approximately 90 ° by a normally fixed cover sheet 3 with a corresponding cylindrical inner surface, this inner surface having a number of fine circumferential grooves 13.
  • a narrow gap is provided between the cover sheet 3 and the roller 1, which enables a smooth rotation of the roller.
  • An inlet channel 4 and an outlet channel 6 with associated cover rails 5 and 7 are connected tangentially to the roller.
  • the inlet channel 4 has a belt guide groove 8 (FIG.
  • Band guide groove 8 of the inlet channel is at most as wide as the opening of the circumferential groove 2, better somewhat narrower (FIG. 4), so that the band 10 can run securely into the circumferential groove 2.
  • the arrangement of the inlet channel is made such that the beginning of the band 10, only a piece of which is shown, comes into contact with the groove bottom first and the other corner 13 of the beginning of the band then along the cover sheet 3 is slid around the curve. This corner 1 engages in one of the circumferential grooves 13 and is thus prevented from jamming in the gap between the roller 1 and the cover sheet 3.
  • FIG. 3 gives an idea of how the band 10 deforms in the circumferential groove 2. Only part of roll 1 is shown. The roller axis 11 is indicated. FIG. 3 can be seen in connection with FIG. 2.
  • the strip cross-section fluctuates between two extreme positions, for example in the cutting planes S1 and S2.
  • the fully extended cross section of the band 10 in FIG. 2 corresponds to the cutting plane S1.
  • the edge of the tape lies against the upper left corner of the circumferential groove 2.
  • strip cross section 10 ' the strip lies almost on the lower groove side wall.
  • the outlet is not critical.
  • the band guide groove 9 of the outlet channel is preferably larger in cross section than the band guide groove 8, so that the shaft deformation which is still partially present when it emerges from the circumferential groove 2 does not cause a braking effect.
  • the essential dimensions in the described embodiment are as follows: Bandwidth 5 mm Tape thickness 0.4 mm Depth of the circumferential groove 6 mm Width of the circumferential groove opening 1.5 mm Diameter of the roll 10 centimeters.
  • the cover sheet 3 and the two cover rails 5 and 7 of the inlet and outlet channels are fastened on a common sheet or other frame and thus together in the direction of the arrows 12 of the fixed channels 4 and 6 and the stationary roller 1 can be moved away.
  • it is a left turn.
  • the cover sheet and the cover rails would have to be stationary and, on the other hand, the roller and the channels should be arranged to be movable.
  • roller 1 is arranged parallel to the conveyor plane or to the plane of the incoming and outgoing belt 10, it could also be inclined in order to make room for conveyor devices, for example.
  • the spatial orientation of the circumferential groove 2 could be maintained unchanged.
  • the circumferential surface of the roll and the inner surface of the cover sheet would then be conical.
