Definitions

  • the present invention refers to a press jaw system, including two press jaws which are adapted to press a pressing material between them, and preferably intended to be applied to machines having press jaws movable in pairs for working upon a movable web of material or similar pressing material, said system being characterized by the fact that the press jaws are associated with pulling means which are arranged to be connected together and to provide the necessary pressing force by drawing the press jaws toward each other, the pressing force exerted by the jaws being wholly or partially compensated internally of the system by a corresponding pulling force in said pulling means.
  • the system according to the invention may be used for press jaws which are utilized for fiat pressing and transverse sealing of a tube to form filled, sealed packages. More particularly in devices of this kind and similar devices which operate with jaws movable along or together with a web of material, problems often arise by large reaction forces having to be taken up, for example by the machine frame. In the system according to the present invention, on the other hand, it is made possible for these reaction forces to be wholly or partially compensated internally in direct connection with the press jaws.
  • FIGURE 1 showing a lateral view of one press jaw belonging to the system, together with a link system which is intended for providing the movement of the jaw, and a detail of the other press jaw
  • FIGURE 2 shows the right hand side of the first-memtioned jaw, as seen from the line AA in FIGURE 1.
  • the system shown as an example includes two press jaws 1 and 2, the jaw 1 being mounted on a turning arm 3 which is mounted rotatable around a pivot shaft 4. On the turning arm 3, with the shaft 4 as a centre, there is further provided a toothed segment 5, which in FIGURE 1 has been shown diagrammatically by drawing the pitch lcircle thereof as a dash and dot line. Also the jaw 2 is mounted on a corresponding turning arm (not shown) connected to jaw 2 and having a corresponding toothed segment 5A which is in engagement with the segment 5. In FIGURE 1, however, these details have been omitted for simplicity.
  • an eccentric axle 6 is rotably mounted in a bearing 7.
  • This eccentric axle 6 at each end carries an eccentric pin 8 and a second eccentrically disposed pin 9, the pin 9 being intended to serve as a mover pin for moving a locking detent 10 mounted on the pin 9 against the action of a spring not shown at the rotation of the eccentric shaft 6 by means of a link 11.
  • this link 11 At one end this link 11 is rotatbly mounted on the eccentric pin 8, while its other end is arranged to carry out a movement which is positively controlled by a link and sliding arm system.
  • Said link and sliding arm system includes a three point link 12 which at one point B is rotatably connected with said other end of the link 11. With a second point C as the centre a guiding disk 16 is arranged on a shaft 13. This guiding disk 16 is mounted stationary in relation to the pivot shaft 4 of the turning arm 3. At a third point D on the three point link 12 the force which is to be transmitted to the turning arms 3 and the jaws 1 and 2 is applied. For example, this force may be carried to the point D by means of a Bowden-cable or similar element which should be able to transmit both pulling and pushing forces. How this takes place is of minor importance to the invention. For this reason this power transmission element has been omitted in the drawings.
  • the point D is caused to perform a positively controlled movement, which in the example shown takes place by means of a rectlinear guide from D to D.
  • the point C moves along the groove 15 in the guiding disk 16 to a position designated by C.
  • the point B moves positively controlled from B till B along the curved line 17.
  • the jaw 1 on the turning arm 3 is turned to the position designated by 1', at the same time as the eccentric axle 6 is rotated. This causes the eccentric line E-F to be moved first to the position designated by F'E" and then rotated with the rotation centre E of the eccentric axle 6 to the position FE'.
  • FIGURE 1 the positions of the points B, C and D corresponding to F have been indicated, which have been designated by B", C and D", respectively.
  • the movement of the point B to B may be provided in many ways.
  • One possibility is to have the link 11 guided direct by a cam guide of the desired shape.
  • the individual detailed constructions will moreover be very much dependent on the actual design of the machine to which the invention is to be applied. In certain cases it may then be suitable to guide each jaw Separately, the system described above generally being duplicated.
  • a press jaw system comprising: a set of press jaws, means to synchronize the movement of one jaw to bring it into pressing relation with the other of said jaws and means to pull said jaws towards one another by exerting a pulling force on one of said jaws.
  • one of said jaws is mounted on a turning arm, a shaft rotably mounted in said turning arm, a pin eccentrically mounted on said shaft, said detent pulling said jaws together being opera bly associated with eccentrically mounted pin.
