DE1007279B - Winding drum for band iron reel with two segments that can be pivoted in opposite directions - Google Patents

Description

GERMAN

The invention aims to improve a known design of drums for such band iron reels from, which have two segments that can be pivoted in opposite directions. When spreading the same will inevitably also cause two terminal strips to close, one of which one on the fixed part of the drum and the other on a segment, d. H. movable, is arranged.

A clamping effect independent of the belt thickness To obtain the strips, the movable terminal strip is now cushioned and according to the invention by means of a spherical head, d. H. freely adjustable, held on the segment.

However, the basic idea of using a terminal strip is, on the one hand, more independent of the tape thickness Cushion clamping effect and on the other hand independent stroke of the clamping rod, at a other reel type with an inner clamp already known. In contrast, the invention in the present Case seen in the transfer of this measure to the type of reel in question here.

Another feature of the invention is that the drum has a clamping point on each segment, d. H. has two mirror-inverted clamping points.

In the drawing, an embodiment according to the invention is shown, namely shows

Fig. 1 is the front view of the object of the invention, while

Fig. 2 shows partly the section AA and partly the side view;

Fig. 3 shows an enlarged section of Fig. 1, namely the clamping device.

The segments 1, which are pivotably mounted about the bolts 2 in the drum body 14, are pivoted apart by the displacement of the wedges 3 and returned to their original position by means of tension springs 19 after the wedges 3 have been released again. The wedges 3 are moved back and forth in the axial direction of the inner shaft via bolts 4, a cross member 5, an inner shaft 6, a lever 7 pivotable about a bolt 8 and a piston rod with piston 9. The piston rod with piston 9 is moved in the cylinder 10 by means of oil or air pressure. The drum body 14 is connected to the hollow shaft 18, which simultaneously represents the bearing and the drive of the tape reel. The band 11, which is pushed between the clamping strips 12 and 13 when the clamping jaws are in the closed position, automatically becomes a winding drum for the iron reel when the clamping jaws are moved apart

with two in opposite directions

pivotable segments

Applicant:

Mannesmann-Meer Aktiengesellschaft,
M. Gladbach

Walter von Dorp, Rheydt,
has been named as the inventor

clamped between the terminal strips. Such a type of reel is known.

It is now the terminal block 12 with the drum body 14 and the terminal block 13 with the Segment 1 connected, according to the invention in such a way that the terminal strip 13 on the ball head 15 a screw 16 is seated and is always pressed against the ball head with the aid of a spring 17.

Claims (2)

Patent claims: 1. Winding drum for band iron reel with two pivotable in opposite directions Segments that inevitably close when the drum diameter is expanded two clamping strips intended to hold the circumference of the band is effected, one of which is attached to one Segment, d. H. movable, and the other is arranged on the fixed part of the drum, thereby characterized in that the movable terminal strip (13) is cushioned in a known manner and by means of a spherical head (15), i.e. freely adjustable, is held on the segment (1). 2. Device according to claim 1, characterized in that the drum on each segment (1) a terminal point, d. H. has two mirror-inverted clamping points. Considered publications:
