Description

Adjusting device and adhesive tape processing assembly

Technical Field

The application relates to an adjusting device and a rubber strip handling assembly for guiding a rubber strip.

Background

The adjusting device is used for compensating the change between the input speed of the adhesive tape and/or the output speed of the adhesive tape. In particular, the adjustment means provide a buffer between the glue strip input and output.

The known adjusting device comprises an adjusting roller, which extends in a direction perpendicular to the direction of transport of the strip of glue. The strip is guided onto a regulating roller to form a loop of strip material as a buffer. Said adjusting roller is movable in a direction perpendicular to the conveying surface of the strip of glue and tends to move away from the conveying surface to automatically adjust the length of the loop, thereby compensating for variations in the length of the strip of glue.

SUMMERY OF THE UTILITY MODEL

A disadvantage of the known device for guiding the strip of glue is that, in order to twist the strip of glue, the strip of glue has to be twisted more than one hundred and eighty degrees, either upstream or downstream of the adjusting device. Thus, due to the stiffness of the strip, it is required to maintain a predetermined minimum strip length between the adjusting device and the upstream or downstream roller in order to allow the strip to twist.

It is an object of the present application to provide an adjustment device which facilitates the twisting of the glue strip and/or reduces the minimum glue strip length required for the twisting of the glue strip.

The first aspect of the application provides an adjusting device, including base and first regulating roller, first regulating roller can rotate around first roller, can remove along adjusting direction for the base to buffer memory rubber belt strip's length, wherein first regulating roller can pivot around first pivot axle for the base, first pivot axle transversely extend to first roller axle.

By adjusting the angle of the adjusting roller relative to the base, the twisting of the rubber strip can be separated on two annular parts, namely the upstream and the downstream of the adjusting roller, so that the twisting of the rubber strip is convenient. The optimum angle may be selected according to the length and angle of each portion of the loop. This minimizes the stretching of the rubber strip and the adjusting device can apply a twist to the rubber strip in a smaller loop than in conventional adjusting devices. Thus, the minimum strip length between the adjusting device and the upstream or downstream roller can be made smaller.

In one of the embodiments, the first pivot axis extends parallel to the adjustment direction and/or in a vertical direction. The adjusting device can thus be pivoted in a plane parallel to the first and/or second transport surface.

In a further embodiment, the first conditioning roller comprises a plurality of individual rotating discs. Thus, friction between the dancer roller and the glue strip due to a difference in speed of the glue strip in a lateral direction, which is transverse to the glue strip path, can be reduced or avoided.

In a further embodiment, the adjusting device further comprises a second adjusting roller which is rotatable about a second roller axis and is movable in the adjusting direction for buffering the length of the further rubber strip, said second adjusting roller being pivotable relative to the base about a second pivot axis, which second pivot axis extends transversely to said second roller axis. Thus, two strips of glue can be conveyed past the adjusting device, each strip passing a respective adjusting roller.

In one embodiment thereof, said second pivot axis is parallel to the first pivot axis. Thus, the adjustment devices extend in the same plane.

In a further embodiment, the first regulating roller and the second regulating roller are symmetrically arranged on both sides of the regulating device. Thus, the adjustment device can exhibit the same cushioning effect.

In a further embodiment, the first adjustment roller is biased in the adjustment direction against the action of gravity. The loop of the glue strip can thus be automatically tensioned by gravity.

In an embodiment thereof, the adjusting device further comprises a counter mass for counteracting the effect of gravity. Preferably, the counter mass comprises a plurality of weights for adjusting the weight of said counter mass. Thus, the biasing force may be adjustable. Moreover, excessive stretching of the strip can be avoided. Thus, damage or breakage to the adhesive tape can be avoided.

The second aspect of this application provides a subassembly is handled to adhesive tape for along adhesive tape route guide rubber strip, include according to this application adjusting device, still include first adhesive tape guide spare for follow adhesive tape route guide adhesive tape along first transmission direction in first transmission face, and second adhesive tape guide spare, lie in along the adhesive tape route for the low reaches of first adhesive tape guide spare, be used for along second transmission direction guide adhesive tape in the second transmission face, adjusting device set up first adhesive tape guide spare with between the second adhesive tape guide spare, the adhesive tape is handled the subassembly and is set up to guide the adhesive tape to pass through along the adhesive tape route from first adhesive tape guide spare adjusting device to second adhesive tape guide spare, first regulating roller set up to be the angle of regulation that the slope extends for first transmission direction.

The treatment assembly comprises an adjustment device according to the present application, thus having the effects described above. In particular, the distance between the adjusting device and the first glue strip guide and/or the second glue strip guide can be reduced compared to conventional handling assemblies.

In an advantageous embodiment, the adjustment angle is an acute angle.

In a further embodiment, the first conditioning roller extends in a conditioning plane parallel to the first transport plane. Thus, stresses in the lateral direction of the strip can be avoided.

In a further embodiment, the second transmission direction is opposite to the first transmission direction. The handling assembly is thus able to reverse the direction of transport of the strip of glue and turn said strip of glue at the same time.

In a further embodiment, the first transport plane is parallel to the second transport plane. Thus, the strip can be turned over more than one hundred and eighty degrees.

In a further embodiment, the second tape guide is arranged above the first tape guide. Thus, the length of the glue strip transported between the dancer roller and the second glue strip guide is larger than the length of the glue strip between the dancer roller and the first glue strip guide.

A third aspect of the application provides a strip handling assembly for guiding a rubber strip along a strip path, comprising a first strip guide, for guiding the glue strip along a glue strip path in a first transport direction in a first transport plane, and a second glue strip guide, located downstream along the glue strip path with respect to the first glue strip guide, for guiding the glue strip in a second transport plane in a second transport direction, said glue strip handling assembly further comprising an adjustment device, said adjusting means being arranged between said first and second glue strip guides, the glue strip handling assembly being arranged to guide the glue strip along a glue strip path from the first glue strip guide through said adjusting means to the second glue strip guide, the adjusting device comprises a first adjusting roller which is arranged to extend at an inclined adjusting angle relative to the first conveying direction.

By adjusting the angle of adjustment of the roller relative to the base, the twist of the strip can be divided between two annular portions, upstream and downstream of the roller. This minimizes the stretching of the rubber band strip and the adjustment device can apply a direction change in a smaller loop than conventional adjustment devices.

FIG. 1 is a strip handling assembly 1 according to an embodiment of the present application. The adhesive tape handling assembly 1 is arranged to handle adhesive tapes, in particular rubber tape strips 9. The strip 9 comprises a first planar or substantially planar side 91 and a second planar or substantially planar side 92 opposite the first side 91.

The glue strip handling assembly 1 is arranged to guide the glue strip 9 along a glue strip path S. The described glue strip handling assembly 1 comprises a first glue strip guide 2 for guiding a glue strip 9 along a glue strip path S in a first transport direction T1 within a first transport plane P1. The presented glue strip handling assembly 1 further comprises a second glue strip guide 3 for guiding a glue strip 9 in a second transport direction T2 within a second transport plane P2. The second tape guide 3 is located downstream of the tape path S with respect to the first tape guide 2. In this embodiment, the first tape guide 2 and the second tape guide 3 are rollers.

As further shown in FIG. 1, the handling assembly 1 is arranged to twist the strip 9 along the strip path S. In particular, processing assembly 1 is arranged to twist glue strip 9 from a first direction at first transport plane P1 to a second direction at second transport plane P2.

In other words, the angular positioning of the adjustment rollers 41,42 relative to the base 40 is adjustable. In particular, the first dancer roller 41 may pivot about a first pivot axis C1 that is transverse to the first roller axis B1. Accordingly, the second dancer roller 42 is pivotable about a second pivot axis C2 that is transverse to the second roller axis B2. In the present embodiment, the first pivot axis C1 is parallel to the second pivot axis C2, and extends in a vertical direction. In other words, the first and second dancer rollers 41,42 extend within the dancer plane P3. The adjustment plane P3 is preferably parallel to the first transport plane P1 and/or the second transport plane P2.

As best shown in fig. 2, each adjustment arm 46 is rotatable about a respective pivot axis C1, C2. The adjustment arm 46 includes a slot 48 that extends circumferentially about the pivot axes C1, C2, respectively. The adjustment rollers 41,42 also each include a fastener 47 that is inserted into a slot 48 of the adjustment arm 46. The fasteners 47 can be loosened to adjust the angular positioning of the respective adjustment roller 41,42 or the fasteners 47 can be tightened to secure the adjustment rollers 41,42 in place.

Both adjusting rollers 41,42 extend at an adjusting angle a relative to the first transport direction T1. In the embodiment shown, the second dancer roller 42 extends perpendicularly to the first transport direction T1. The first adjusting roller 41 extends at an adjusting angle a with respect to the first conveying direction, which is inclined, in particular acute.

When both of the dancer rollers 41,42 are in a position extending perpendicular to the first conveyance direction T1, the first roller shaft B1 is aligned with the second roller shaft B2. In this particular case, the adjustment rollers 41,42 are arranged symmetrically with respect to the sliding carriage 45. However, as shown in fig. 2, the adjustment rollers 41,42 may also be arranged asymmetrically.
