SU104051A1 - A device for rewinding paper tape to reel recorders - Google Patents

Description

The subject of the invention is a device for rewinding a booming tape onto reels of recording apparatus with

two pairs of centering heads ALYA install paper, reel; ki and roll

A device for rewinding paper tape on a coil of recording instruments with two pairs of parallel-arranged sliding center heads with rotating tangent, one pair of which, designed for mounting the coil, is made driven, is known.

The described device differs from the known ones in that it is equipped with a device that provides a change in the tension of the winding tape when the width changes, as well as when the roll diameter changes during the rewinding process, which is necessary to maintain the specified tension conditions of the tape.

FIG. 1 shows a general view of the device; in fig. 2-circuit braking device.

The device has two pairs of parallel spaced center pivots with rotating centers. Pair 1, 2 is intended

for installation of the device roller and equipped with a manual drive 3 and an electric drive 4. Pair 5, 6 is intended for installation of a roll of paper.

Center heads / and 5, located on the left side of the device, can be rotated along cylindrical guides in the axial direction with the help of rack mechanisms, which is necessary when changing the width of the rewindable paper.

The center heads / and 2 are connected between themselves by a flat pantograph mechanism 7 (Fig. 2). When the grandma moves, this mechanism moves apart or slips.

The tension of the belt is adjusted by means of the brake levers 8, 9 of the rotating centers. These levers are connected by a ruler 10 parallel to the center axis. The ruler is simultaneously affected by buffer springs 11, 12 of a cylindrical sliding pair located perpendicular to the ruler. The sleeve / 5 of this pair is connected with the middle hinge 13 of the pantograph mechanism 7, and the hollow cylindrical rod 14 is connected with the swivel presser foot 15, resting 1, it is on the surface of the roll. The action of the mechanism 7 through the spring // and ruler 10 on the levers 8, 9 eliminates the automatic change of tension and changes the iirin of the tape, and influences the focus.

Claims (3)

1. A device for rewinding paper tape on reels of self-closing devices, equipped with two pairs of parallel, sliding, sliding centers with turn-on centers, one pair of which is designed for mounting the coil of the device, made driving, characterized in that The provision of a certain tension force, which automatically changes depending on the type of paper tape, the pair of attendants, when the tape is reattached, is intended to set the bobbin of the roll, connected with the passage between the heads Flat pantograph mechanism, the average luapiinp which is associated with the brake levers vrash, ayuschihs centers tse T | -rovyh attendants. 2. Device but n. 1, characterized in that, with the aim of automatic opening of the tabs / 5 and levers 8, 9, through the spring 12 and the ruler 10, the tension force is automatically varied as the roll diameter changes in the rewinding process. Mathematically changing the tension force when changing the diameter of the coil during the rewinding process, the device is equipped with a pivot presser foot on the surface of the coil, which is connected to the locking levers of the rotating centers. 3. A device according to claim 1 and 2, characterized in that, in order to provide a simultaneous impact of the pantograph and the pressure pad lia, the brake levers are rotatable; 1 centers, both brake levers are connected by means of a parallel axis of the centers of the ruler under the influence of two buffer springs perpendicular to it) aspololyi with a cylindrical skid; bushing of a bunker, the sleeve of which is connected with the middle ball and hollow drift; pin 1 with a rotary presser foot.  f   fe u vH GU A Gu oilrw EiijsaitnaiE , | k1IiPv1ZHCH GM1
