Definitions
- the present invention relates to a method for driving the sealing elements of a packaging machine according to the preamble of independent patent claim 1 and a device for carrying out the method according to the preamble of patent claim 2.
- US Pat. No. 4,291,520 provides two separate sealing points for longitudinal seams and transverse seams.
- the hose is drawn off by means of a separate conveyor drive.
- the cross sealing jaws are driven separately and follow the bag on part of the way. If the hose is to be pulled off intermittently, this has a major influence on the heating power of the longitudinal seal, because the film material is moved unevenly through the sealing point and thus forms differently heated points.
- the bag lengths can be changed relatively easily, namely by The speed of the trigger is changed.
- the disadvantage is the synchronization of all three parts, namely the control of the longitudinal sealing means, the removal device and the movement of the transverse sealing jaws when the bag length changes.
- the object of the present invention is accordingly to create a drive for the sealing elements with simple adjustment and change of the bag length.
- the individually produced, filled bags B are gripped by a pair of pliers 12 and placed on a conveyor belt 13.
- the band-shaped packaging material V can be divided into two partial webs V1 and V2 in accordance with CH-A 416 434. To simplify the drawing, the supply roll located behind the hopper 1 and the separating knife are not shown. After separation, the two partial webs V1, V2 are brought into opposite webs B1, B2 via a first guide roller 14, a second guide roller 15 and two third guide rollers 16.
- the strips of the webs B1 and B2 reach the pair of sealing disks 6 away from the guide rollers 8.
- the hollow mandrel 4 is designed for a specific filling material, as any person skilled in the art should understand easily. Through the hollow mandrel 4, the filling material, measured for example by weighing, can freely pass from the filling funnel la into the bag.
- Fig. 2 the two webs B1, B2 are indicated as they enter the longitudinal sealing rollers 6.
- the wrapping of the sealing rollers 6, which is correctly shown in FIG. 1, has been dispensed with.
- the two sealing rollers 6 are coupled to one another by means of a pair of gearwheels 17, so that they are rotated together but in opposite directions.
- transverse sealing jaws 9 are only hinted at, the drive for opening and closing the jaws is omitted, in particular because this is not essential for the invention and is known to any person skilled in the art.
- the axis 20 of the one sealing roller 6 carries in its extension 21 two gears 24, 25 held on freewheel assemblies 22, 23.
- the freewheel assemblies are also well-known machine elements, such as those used by the Stieber Division of Borg-Warner Corporation under the designation NSS in the Trade. So that both gears 24, 25 are rigidly coupled in the same direction of rotation according to arrow A with the extension 21 and in the direction of rotation according to arrow B they rotate at idle
- Two racks 30, 31 are connected in one piece in a fork-like manner to a common carrier 32.
- a two-armed lever 33 is rotatably hinged at one end.
- This two-armed lever 33 is rigidly connected approximately centrally with a shaft 34 which is rotatably mounted on the frame of the packaging machine.
- a connecting rod 36 of an eccentric drive 37 is articulated.
- the carrier 32 is guided in a guide block 38 for a translatory back and forth movement.
- a gear 25 meshes directly with one rack 31 and the other gear 24 is in engagement with the other rack 30 via a freewheel gear 26.
- a movement of the gear rack 30 in the direction of arrow C causes the gear wheel 24 to rotate in the direction of arrow A.
- arrow D of the gear rack 30 turns the gear 24 freely.
- a movement of the rack 31 in the direction of arrow E causes a rotation of the gear 25 in the direction of arrow B, ie an idling movement.
- a movement of the rack 31 in the direction of arrow F is transmitted to the extension 21.
- Arrows which cause rotation of the extension 21 and, by means of the shaft 20, a rotation of the sealing rollers 6, that is to say the arrows A, C, F, have been shown filled in.
- the arrows for directions of rotation which do not cause the sealing rollers 6 to rotate, that is to say the arrows B, D, E, are shown as empty triangles. This arrangement thus brings about a two-stage rotation of the sealing rollers 6, namely a first stage when moving in the direction of arrow C and a second stage when moving in the direction of arrow F.
- the transverse sealing jaws 9 are connected to the shaft 34 via a lever arm 39, so that the movement of the eccentric drive 37 is transmitted to the shaft 34.
- the transverse sealing jaws 9 execute a reciprocating movement.
- the stroke of the transverse sealing jaws 9 is approximately the same as the stroke of the toothed racks, so that the feed of the bags can be adjusted to approximately twice the stroke of the transverse sealing jaws.
- the eccentric drive 37 consists of a pulley 40, which is driven by a drive belt 41 from a motor, not shown. To change the bag length, only the stroke of the eccentric drive 37 needs to be adjusted. For this purpose, a radial slot 42 (FIG. 3) can be provided in the pulley 40, so that the point of application of the connecting rod 36 can be changed radially by means of screw 43 and nut 44.
- Markings 51 on the bags can be monitored by means of a light barrier 50.
- An electromagnet 52 is actuated via an amplifier (not shown) and possible further electronic control means, which are also well known, and its armature 53 supports a scanning lever 54.
- This scanning lever 54 is biased by a spring 55 against a cam disk 56 which is rigidly connected to the pulley 40 by means of a shaft 58. If the light barrier does not emit a signal from a marking 51, the scanning lever 54 is released and a plunger 57, which carries the freewheel gear 26, pulls it downwards. Thus, the gear 24 is rotated by a small amount in the direction of arrow A and the marker 51 is pushed down the corresponding distance. This process can be repeated with each rotation of the pulley 40.
