Abstract

The arrangement of the drive of the feeding crossbar, intended especially for a multiple feeding device of bar material with a magazine, which drive consists of a link chain and a drive rotary motor with a clutch, or a rotary hydraulic motor. The solution to the problem is the possibility of automatic adaptation of the feeding device to different lengths of bar material, stored alternately in one common magazine and its reliable feeding. This is achieved by reducing the number of feeding crossbars from three according to the current state of the art to two according to the proposed state, which two feeding crossbars are arranged symmetrically

Description

1 21 1563

The present invention relates to a drive beam drive arrangement for a multiple bar material feed device with a cartridge which consists of a link cell and a rotary drive motor with a clutch or rotary motor.

This so far known multiple feed device of bar stock with container j, provided by three feed bars, mounted on a link chain in three equal ranges, equal to the length of the aligned bar material, the length of which has to be permanently maintained in this case. The fulfillment of this condition, resulting from the function of the prior art multi-feed device of bar stock with a container, is in practice unsuitable because the bar material is not produced in exactly the same length and considerable loss would occur when aligned.

The above drawbacks are eliminated by the arrangement of the feed conveyor drive according to the invention, the essence of which is that it is based on an articulated. the chains are symmetrically fixed by two feeder trays, with a rotary hydraulic motor or a continuous torque device mounted both in the mud and in motion on the articulated chain drive wheel.

Advantages and advantages of the displacement drive arrangement according to the invention are mainly due to the fact that, in conjunction with the multiple feed device of the bar stock with the container, it allows automatic adjustment of this feed device to a length of bar material disposed alternately in one common container and its reliable administration. An example of a displacement displacement arrangement according to the invention is shown in the drawing in which FIG. 1 is an elevational view and FIG. 2 podorysný pohlad. for such an arrangement.

The main parts of the drive arrangement of the feeding beam according to the invention are: link chain, drive wheel 15, rotary hydraulic motor 9, or other drive device.

Two feeder crossbars 1, 3 on the hub 15 are mounted symmetrically on the link refilter. the link chain is connected to the rotating hydraulic motor or drive gear by a permanent torque both in the mud and in the motion.

The function of the drive of the feed cross member according to the invention is as follows: Feeder 13, whose face 16 rests against the feed bar material 11, is moved in a forward direction 17 by spring latches 12 and straight ratchets 14, the second feed bar 13 being moved by the link chain 4. to the starting position. The rotary, hydraulic motor 9, or other suitable continuous torque drive device, presses the delivery cross member 13 onto the feed bar material 11 with a constant force that is less than the frictional resistance of the bar 11 being fed.

As soon as the feeder cross member 13 executes the last stroke, the rear face 3 of the feeder cross member 13 leaves the face 10 of the guide flap 7 and by pulling the link chain 4 by the pressure of the bar material 5 in the container 12, the feeder cross member 13 is pushed downwards 8. The face 16 of the feeding cross-member 3 leaves the feed bar material 11 and on the guide plate 7 a further feed bar material 6 '

In order to guarantee a reliable function, the last cross bar 13 feeds the bar material 11 about 1 mm behind the container wall 2 As soon as the entire bar 13 leaves the bar 11, the rotating hydraulic motor or other supercharger starts to rotate with its constant torque. the wheel 15 and the link reel 4 carry the free feeder cross member 13 until its face 16 abuts against the other rod 6 being fed. *

Since the frictional resistance of the other bar stock being fed is greater than that of the feed bar 13 exerted by the constant torque from the rotary hydraulic motor 9 or the drive device, the feed bar 13 stops and its spring-loaded latches 12 are provided for a new feed shot with straight ratchets 14.
