Definitions
- the invention relates to a method and a device for applying tapes, namely tear tapes or the like, to a transported material web according to the preamble of patent claim 1 and patent claim 2.
- the outer wrappings of packs are usually provided with a tear-on tape that is welded on or glued on.
- the blank of the wrapping is separated from a continuous, uninterrupted web (wrapping material web).
- the separately produced tear tape separated from a ribbon web, is placed and connected to the wrapping material web.
- the invention is based on the object of proposing a method and a device for merging and uniting ribbons and wrapping material web, in which or at which the machine is operated at high working speeds and yet a flawless and material web-friendly transfer of the separated ribbon to the wrapping material web is ensured.
- the web of wrapping material is in fact transported continuously.
- a certain section of the wrapping material web is moved discontinuously, namely in cycles, with respect to the remaining part.
- the device according to the invention is provided with guides, namely deflection members, in particular deflection rollers for the web of wrapping material, which can be moved back and forth simultaneously on both sides of the transmission section. These are moved in such a way that the area between these deflecting elements, including the transmission section, stands still during one phase, so that the tear tape fed from below or above can be transferred to the web of wrapping material without any problems. Then this section is given a correspondingly higher, compensating speed by counter-movement of the deflection members.
- the deflection rollers are arranged on rockers, which form complementary web loops that build up and break down.
- features of the invention relate to the design and arrangement of the rockers and their drive. Furthermore, features of the invention relate to the design of the separating device for producing the tapes.
- strips 11 separately produced are applied to a wrapping material web 10 and connected by thermal welding.
- the wrapping material web 10 can be made of cellophane and the ribbon 11 consist of an appropriate material.
- the tapes 11 are brought up to the wrapping material web 10 from below, with the longitudinal axis pointing in the conveying direction of the wrapping material web 10.
- the transfer of the ribbon 11 to the wrapping material web 10 takes place in the region of a transfer section 12 of the wrapping material web 10. This runs essentially horizontally or slopes slightly in the transport direction.
- the transmission section 12 is essentially delimited by deflection rollers 13 and 14.
- the transfer section 12 stands still at the moment of transfer of the ribbon 11, while the wrapping material Y ahn 10 is continuously conveyed outside of this section, preferably at a uniform speed.
- the transfer section 12 is correspondingly accelerated after taking over the ribbon 11.
- web loops 15 and 16 are formed, which complement one another to an always constant overall size of a “web supply”.
- the web loops 15, 16 change their size continuously during the non-uniform, intermittent movement of the wrapping material web 10 in the region of the transfer section 12 or in the region extending between deflection rollers 17 and 18 of rockers 19 and 20.
- the above-mentioned rockers 19, 20 produce the changing web loops 15 and 16 by means of a swiveling pivoting movement.
- the respective end positions of the rockers 19, 20 and the deflection rollers 17 and 18 arranged on them are shown by solid or dashed lines in FIG. 1 .
- the web loops 15 and 16 are formed in the present case by the deflecting rollers 17 and 18 between fixed counter-rollers arranged at an appropriate distance from one another.
- the rocker 19 is assigned two deflecting rollers 21 and 22 which are arranged one above the other at a distance.
- the web loop 16 is formed between the deflection roller 14 at the end of the transfer section 12 and a deflection roller 23 arranged at a distance below it.
- the section stopped during the transfer of the ribbon 11 is longer than the transfer section 12.
- a pair of guide rollers 24 is provided here.
- the synchronous drive of the rocker arms 19, 20 takes place here via a common drive arm 25, which is moved back and forth in a pivoting sense and which is connected to the two rocker arms 19, 20 via push rods 26 and 27.
- the rockers 19, 20 including the drive arm 25 and a number of the deflecting rollers are mounted here on a common support plate 28 of the device.
- the flat transfer section 12 of the wrapping material web 10 is guided over a fixed table 29. Its support plate 30 for the wrapping material web 10 is inclined downwards in the conveying direction. A counter plate 32 is formed below the support plate 30 with a wedge-shaped intermediate piece 31. This is part of a separation and transmission unit 33 for the ribbon 11.
- a ribbon web 34 runs below the table 29, namely directly below the counter plate 32 in the direction transverse to the conveying direction of the wrapping material web 10. Below this, the ribbons 11 are each cut off at the free edge of the ribbon 34, that is to say transversely to the conveying direction thereof. The tapes 11 are accordingly fed with their longitudinal axis lying in the conveying direction or longitudinal direction of the wrapping material web 10 and attached to the underside thereof.
- the ribbon web 34 is fed to the separation point by a traction unit 35.
- This consists of a lower, cyclically rotated drive roller 36 and a counter roller 37 extending above the ribbon track 34.
- the drive roller 36 is driven by a reciprocating arm 38 in each case around a feed section of the ribbon track 34 in the direction of rotation.
- a freewheel 39 designed in the usual manner brings about a drive-free return of the drive roller 36 into the starting position.
- the free front end of the ribbon web 34 is clamped in at the moment, namely for the moment a separating cut is being carried out.
- a clamping strip 40 with elastic support 41 is moved against the ribbon 34 and presses it against the underside of the counter plate 32.
- the ribbon 34 is controlled so that it is slightly, namely about the width of a ribbon 11, about the counter plate 32 protrudes. This protruding end is separated by an up and down movable cutting knife 42 by upward movement.
- the counter plate 32 or its edge facing the separating knife 42 acts as a counter knife.
- the separating knife 42 is provided with suction bores 43 on the upper side, namely in the area of the support of the ribbon 11. These are subjected to negative pressure at the moment of separation and afterwards. As a result, the cut ribbon 11 is fixed on the top of the cutting knife 42. In the further course, this acts as a transport organ for the ribbon 11 until it lies against the underside of the wrapping material web 10.
- the table 29 or its support plate 30 is provided with an elongated opening 44 in the region of the movement path of the cutting knife 42. Through this the upper part of the separating knife 42 with the ribbon 11 passes through until it abuts the web of wrapping material 10.
- an elongate, rod-shaped counter-holder 45 is arranged such that it can be moved up and down. The latter receives contact with the wrapping material web 10 on the opposite side thereof when the ribbon 11 is fed.
- the counter-holder 45 is equipped with a heating cartridge 46 in the present case. This enables the ribbon 11 to be fixed to the wrapping material web 10 by thermal welding.
- the above-described movable parts of the separation and transmission unit 33 are not moved in a translatory manner, but in a pivoting sense.
- the separating knife 42 can be moved about a pivot bearing 47 by a tension spring 48, by means of which the separating knife 42 is always preloaded in the direction of the wrapping material web 10.
- the opposite movement can take place here via a shaft extending in the area of the pivot bearing 47.
- the counter-holder 45 can also be pivoted, specifically around the axis of the deflection roller 14.
- the swivel drive can take place through the shaft extending in the region of the bearing or the deflection roller 14.
- the suction bores 43 of the separating knife 42 are supplied via a central suction line 49.
- the wrapping material web 10 is driven by drive means, not shown in detail here, in particular pulling roller pairs, namely continuously drawn off.
- the pivoting movement of the rockers 19, 20 is controlled synchronously with the separation and transmission unit 33.
- Fig. 1 the moment of reversal of movement of the wings 19, 20 is shown. This causes the transmission section 12 or the area of the wrapping material 10 between the rockers 19 and 20 to come to a standstill. During this standstill phase, the material loop 16 is increasingly built up, while the web loop 15 decreases.
- the movement of the rockers 19, 20 takes place, with the result that the area of the wrapping material web 10 between the rockers 19, 20 is accelerated to a correspondingly higher speed. Accordingly, counter-current movements or correspondingly increased synchronous speeds are generated quasi in this area.
