  • ABSTRACT [30] Foreign Application Priority Data Ma ⁇ ' 27. 1972 Germanv .1 22259014 A machine the tying of Packages WhiCh Compriscs l a tying arm extending above the package and moving 52 U.S. c1. .v 100/27 around An ekmgflted fir clement w COM p 51 1111. Cl B6Sb 13/10 Or Wire) is fed to the arm from a pp y drum- The [53] Field of Search 100/27 3 1 53 9 tying arm moves around the drum and the tying arm is arranged on a shaft.
  • Machines having a double-arm tying device are also known.
  • the one arm serves for placing the tying element around the package, while the other arm carries the supply drum. Twisting can thus be practically avoided, but increased power is required for the operation of the machine. Furthermore, it is necessary to provide a correspondingly large brake device in order to stop the tying arm after placing of the tying element around the package.
  • a machine for the tying of packages (having a tying arm, which extends above the package and moves around it, to which arm the tying element is fed from a supply drum, the supply arm moving around the tying drum, which is arranged on the shaft of the tying arm).
  • the tensioning device By means of this tensioning device, such an intermediate amount can be stored, that a certain amount of storage is always present, even in the case of large packages. If the tractive force exceeds a predetermined value, the tensioning device brings the brake of the supply drum into a release position.
  • the tensioning device is simple in its construction. It consists essentially of a swing arm arranged on the tying arm and bearing a guide roller on its free end; it is provided with an eccentric on its articulated end. When a certain position of swing is exceeded, the eccentric then actuates the brake which is operatively connected to the supply drum.
  • the brake comprises a jaw brake constructed in such manner, that the eccentric of the swing arm lies between the free sections of the brake jaws.
  • the drum on the axis of the tying arm, is secured in its attached position indirectly by a vertical wall of the supplementary table.
  • the supplementary table can be brought by simple manipulation out of engagement with the axis of the tying arm.
  • the supplementary table also serves to support the packages placed on the machine table. The supplementary table and the machine table leave a gap between each other, through which gap the tying element is conducted.
  • FIG. 1 is an elevation of the machine showing an intermediate position of the tying arm.
  • FIG. 2 is an elevation of the upper portion of the machine shown on an enlarged scale
  • FIG. 3 is a longitudinal section through the machine drawn to the scale of FIG. 2.
  • the machine comprises a machine frame 2 provided with legs 1.
  • the machine frame 2 carries the tabletop 3.
  • a drive 4 and a welding unit 5 arranged below the tabletop 3.
  • the columns 6 are connected by a horizontal cross member 7.
  • the latter is provided with a collar 8 welded thereon.
  • Cross member 7 and collar 8 serve to receive the tying-arm shaft 9.
  • the tying-arm shaft 9 is provided at its end with a threaded section 10, which serves to receive the threaded nuts I].
  • the tying-arm shaft 9 has stepped sections l2, l3 and 14. On section 12 there are antifriction bearings 15 on which is mounted the tying arm 16. In the region of the anti-friction bearings 15, the tying arm 16 is provided with a supporting ring 17. The latter is provided on the end facing the cross member 7 with a sprocket wheel 18 on which a chain 18 (FIG. 1) leading to the drive 4 acts. Via this sprocket wheel 18, the tying arm 16 can be swung around the shaft 9 of the tying arm.
  • the stepped section 13 supports the bushing 20 by means of the antifriction bearings 19. At the end thereof facing the section 12, a disk 21 is welded. The said bushing receives the sleeve 22 of the supply drum 23.
  • a recess 24 is provided in the free end of the bushing 20.
  • a pot-shaped bushing 25 In the recess 24 there is guided a pot-shaped bushing 25.
  • the edge 25' of the pot bears at its end a supporting disk 26 for the supply drum 23, while the bottom 25" of the pot is acted on via an antifriction bearing 27 by a compression spring 28.
  • This compression spring 28 rests against a collar 30 of a bushing section 33 rigidly connected with the vertical wall 31 of the supplementary table 32.
  • a sliding bolt 34 for the mounting of the bushing section 33 on the stepped section 14 there is employed a sliding bolt 34 the fork tines 34' of which extend over flattened portions 14 lying parallel to each other of the stepped section 14.
  • the flattened portions 14' are so large that they permit a slight axial displacement of the bushing section 33 on the stepped section 14 in the direction indicated by the arrow .r.
  • the bushing section 33 is always held in the one end position by means of the compression spring 28.
  • the compression spring 28 provides, via the pot-shaped bushing and supporting disk 26, an axially nondisplaceable seat for the supply drum 33 on the bushing 20.
  • a lock screw 35 which passes through a longitudi nal slot 36 in the bolt 34.
  • the lock screw 35 extends from the vertical wall 31 of the supplementary table 32.
  • the lock screw 35 For the changing of the tie supply drum, the lock screw 35 must be loosened. The bolt 34 must then be shifted in the direction indicated by the arrow y in such a manner that the tines 34' of the bolt 34 move back completely from the flattened portions 14' of the stepped section 14. Thereupon the supplementary table 32 together with the bushing section 33 and the pot-shaped bushing 25 and support disk 26 can be withdrawn from the shaft 9 of the tying arm. In order to facilitate this withdrawal of the supplementary table 32. the end supporting surface 32' of the supplementary table 32 is swingable around the hinge 29 into the position shown in dot-dash lines in H6. 3. After the insertion of a new supply drum 23, the above-mentioned parts are again brought into the position shown in the drawing.
  • the tying arm 16 moves around the drum 23 in the direction indicated by the arrow 1. This direction corresponds to the direction of unwinding of the tying ele ments.
  • the tying arm 16 is angular. It consists of the two angle legs 16 and 16".
  • the leg 16' provided with the supporting ring 17 is provided with a bearing pin 37.
  • Eccentric 39 and swing arm 38 are rigidly connected with each other.
  • the swing arm 38 is under the action of a torsion spring 40 which urges the swing arm in the direction indicated by the arrow u.
  • the end position of the swing arm 38 is limited when the radially protruding sections 39' of the eccentric 39 strike against the corresponding pin-like stops 41 of the tying arm 16 (See FIG. 2).
  • the eccentric 39 extends between two paralleldirected sections 42 of the brake jaws 43.
  • the latter are supported on the side of the tying-arm shaft 9 opposite the eccentric 39 on corresponding pins 44 of the tying arm 16.
  • the brake jaws 43 rest against the outer surface of the brake ring 45 which is connected in suitable manner with the disk 21.
  • This brake position is maintained by a tension spring 46 which extends between the parallel-directed sections 42 of the brake jaws 43.
  • the swing arm 38 at its free end bears the tyingmeans guide roller 47.
  • the angle leg 16' of the tying arm 16 bears a guide roller 48 which lies on the same plane as the tyingmeans guide roller 47.
  • the further guide rollers 49, 50 and 51 which lie in relatively staggered planes are rotatably supported.
  • the guide rollers 50 and 51 are seated on an end angle piece 52 of the leg 16".
  • the tying element pulled off from the tyingmeans drum 23 is placed in the path indicated by the arrow over the guide rollers 49-51.
  • the tying element is a flat plastic tape guided so that the element leaving the guide roller 51 rests with its wide surface parallel to the surface of the package and in this way permits a twistfree placing of the tying element around the package.
  • FIG. 1 there is shown in dot-dash lines the starting position of the tying arm 16.
  • the swing arm 38 which forms the after-tensioning device has stored an unwound intermediate supply.
  • the end of the tying means is located, in accordance with the starting position, in a clamp 54 of the welding unit 5.
  • the tying arm then again assumes the position shown in dot-dash lines in FIG. 1. Due to the tensile stresses occuring upon the tying of the package, the swing arm 38 can move in opposition to the direction in which it is urged by its spring.
  • the eccentric 39 After exceeding a certain position of swing, the eccentric 39 strikes the sections 42 of the brake jaws 43 which in their turn move away from the outer surface of the brake ring 45 and permit rotation of the tying-means drum 23. In this way, excessively large withdrawal tensions in the tying means are excluded. After the tying means have been placed in this manner around the package, the ends of the tying means can be tied and the tying means cut, but in such a manner that the end of the tying means is held by the clamp 54.
  • An apparatus for tying a package by slinging a tying element therearound comprising;
  • a tying arm swingably mounted on said support for slinging said element about said package from an end of said arm;
  • a supply drum mounted on said support with its axis coinciding with said swing axis for feeding said element to said arm;
  • said device comprises a swing arm pivotally mounted on said tying arm; spring means biasing said swing arm relative to said tying arm in one direction, a guide roller on a free end of said swing arm and engaging said element, and eccentric means operated by said swing arm and connected to said brake.
