Field of application of the invention The Eifindung relates to a shearing device, preferably for profile glass with wire insert. The device is particularly suitable for the shearing of preferably inserted in U-profile glass wires directly

after breaking the glass, especially on the continuously produced glass strand.

It is advantageous bsi profiled glass with wire insert as well as for shearing wires of the wire or Drahtornamentglases

applicable.

The device is intended for use in the glass industry. Characteristic of the known state of the art The construction of known technical solutions is based on the utilization of relative movements between

glass pieces to be separated to the continuously transported glass strand or glass ribbon (DT-PS 649127). At the same time, the piece of glass to be separated is removed from the glass ribbon at a lower speed at a higher speed. This has the disadvantage that the wire inserts succeed and after separating wire ends protrude from the peeled glass piece and the continuously running glass band and Auesplitterungen the finished product denier reduce the quality.

The solution, which was set forth in DE-AS 2213969, carries the different glass dimensions (leg height, profile width)

not bill.

The shearing of the wire reinforcement shown in WP 248794 by means of sliding carriage, train-pressure rod and geared motor

means a drive effort additional to the BrechwaUenantrieb. In addition, due to the large distance to the

Breakage and the shearing off of the wires in an unenhanced position of the glass strand Chipping on the profiled glass End surfaces can not be completely avoided. Dio in the AT-PS 382 603 explained variant of breaking armienen glass strands using burner flame and the Shearing * by means of abrasion has some disadvantages in terms of shearing off the reinforcements Shearing is not done simultaneously, the legs of the U-profile glass and abzuscherenden piece of glass touch each other

during the shearing off. In addition, the sheared glass piece is not printed after shearing back to the starting position.

Object of the invention

The invention is based on the objective of developing a shearing device, preferably for profiled glass with wire mesh, which, in addition to reducing the outlay for the Brtch shearing process and the space requirement, primarily contributes to the further reduction of chipping on the glass.

When shearing the wire insert, the legs of the successive glass pieces should be at a distance from each other, with the aim that chipping on the glass are prevented and thus a consistently good quality of the finished products is guaranteed.

Explanation of the essence of the invention

The invention has for its object to break U-Profilglax pieces in the continuous manufacturing process during transport of the glass strand and shear the wire insert, so that the U-profile glass pieces can be abgetraqen in finished length of the production line i. When shearing it should come after breaking no additional chipping.

Erfindungsgomiß the object is achieved by a shearing device, preferably for F. jfilglas with wire insert, in which a transversely to the conveying direction of the breaking U-profile glass stocked with sliding rollers sliding piece is arranged axially displaceable on olner crushing roller and HalUrollen atf the crushing roller arranged axially fixed are, preferably such that a

Retaining rollers and a sliding roller for different width U-profile glass is adjustable, un-r ¹ that an outer cam and a Inside cam plate are arranged, which are fastened with screws on the front sides of the sliding piece, and the Cams, preferably ball-bearing, attached to the crushing roller bearing rollers are assigned. Sliding and Retaining rollers are advantageously designed keglig, the Kegligkeit is 2% to 5%. The solution is particularly characterized by a transversely to the conveying direction of the breaking U-profile glass with slide rollers

stocked sliding piece and arranged on the crushing roller retaining rollers, which are designed to be adjustable according to the U-profile width.

The device is advantageously designed in that the sliding rollers at the same time, d. H. if the retaining rollers the Guide the glass strand sideways and lift the crushing roller, the U-profile piece and the glass strand, abut the U-profile piece. A further advantage is that the glass strand not bent horizontally and the U-profile glass piece after breaking and Shearing is returned by the sliding rollers in the output direction, whereby the positioning accuracy for the

subsequent removal device is ensured.

The device is also advantageously designed in that all device parts below the glass transport plane

are arranged and are only above this during the crushing and Abschr rvo.'ganges.

Advantages are also in the structure of Schtebemechanisnvjs by means of cams, whereby no separate drive

necessary is. The small distance in the direction of rotation of the Brichwalze successively arranged sliding and holding rollers ensure the initiation of the shearing immediately after breaking the glass strand in its raised position, whereby no additional chipping occurs.

In the event that the profile glass legs are inclined slightly outwards, the arrangement of conical retaining rollers and conical Sliding rollers advantageous because too high bending stress of the profile glass leg, which can lead to breakage, prevents The construction of the sliding and holding rollers is designed to accommodate forces of the order of 100 to 400N

become.

The profile glass strand passes after passing through the cooling path on a roller conveyor first to the cutting device, then to Crushing, shearing device. After the interface of the glass strand has reached the crushing roller, it becomes in Rotary movement brought and the crushing bar raises the glass strand, causing it breaks. At the same time are the Retaining rollers next to the glass strand and the sliding rollers next to the U-profile glass piece immediately before the break point. At the same time, the outer cam plate with its cam extends to the roller mounted on the crushing roller bearing, whereby

over the ski piece and the slide rollers the U-profile glass piece against the held by the holding rollers

Profilglasstrang advanced and sheared the inserted wires werdon. The inner Kurvenscheibi secured by an appropriate design on a mounted on the crushing roller bearing roller

(Immediately after the shearing off of the wires) the return movement of the backward movement directed against the shearing direction

Sliding piece, the sliding rollers of the U-profile piece. Due to the further rotation of the crushing roller to its starting position of the glass strand and the U-profile piece

lowered onto the roller conveyor and brought holding and sliding rollers below the glass plane.

Thus, a continuous-working crush-shear device was developed, taking advantage of by the Crushing roller »initiated rotary motion of the mechanism for shearing the wire inserts is driven. In addition to the Saving a second drive for the shearing and the associated space saving creates the advantage that the Wires are sheared off when the glass is raised at the break point and the legs of the successive glass S'.ücke have a distance from each other, wcdurcii chipping on the glass are prevented and thus a consistent

good quality of the finished products is created.
