DE2511625A1 - Counting circuit measuring and monitoring pile length - with counters relating pick numbers to warp length, esp. for towel looms - Google Patents

Abstract

An arrangement of counting mechanisms for measuring and monitoring the length of pile yarn feeding into a loom, esp. a towel loom, during a definite number of revolutions of the main shaft, includes a first pre-selectable impulse counter which can be set back to zero, and which receives the impulses from a device actuated by a thread length measuring wheel; and a second similar impulse counter receiving impulses generated by the main shaft; the counting process of the first impulse counter being interrupted by the second impulse counter, when the pre-set count number has been reached. To register the length of the threads, two adding impulse counters (Z1, Z2) which can be set back to zero electrically, and which have electrical switches, are provided. These can be set back to zero by a pre-contact switch (14) and connected to the impulse signaller (24) of a thread length measuring wheel by a preselected impulse counter (Z3) which can be electrically reset to zero, and which registers the revolutions of the main shaft. This is associated with the pre-contact with (14) and zero contacts controlling a switching circuit. In which there are two sets of contacts (29, 33). Contacts (33) effect the alternating connection of the impulse signaller (24) to the counting magnets of the counters (Z1, Z2) registering the length of the thread, and at the same time, contacts (29) effect the alternating switching of resetting magnets of these counters (Z1, Z2) to the pre-contact switch (14) of the counter (Z3) for the revolution ions of the main shaft. Measures continuously and monitors the running of the pile threads in separate machines, esp. in towel looms.

There is already a Fedeneinlaufmeßger @ t known (DT-OS 2 061 170), with which several warp beams can be measured in one measuring process.

It is provided that in a portable device several electrical Pulse counters are provided which show the revolutions the main shaft, Measure the run-in thread length and, if necessary, the length of the fabric. Which is the drive of the Create a pulse counter for the run-in thread length and, if necessary, for the fabric length Pulse generators are stationary attached to the measuring points of the textile machine. Of the electrical impulse transmitter for the impulse counter of the main wave has a readable Coupling.

The main disadvantage of this known meter installation is that continuous measurement and monitoring is not possible because both Main wave counter, as also the Fadenkängenz @@@ lar after each @@ Mafvorgang @ Again manually reset are @issen and each neve @ eßvergang initiated manually @@@@ got to.

A @ fg @@@ the present invention is to provide a counter arrangement of the Incoming g @@@@ nte @ Art to see that with the least possible effort Registration and monitoring of the pile thread infeed of the individual textile machines, in particular Prottierwebst @@ len, erl @@@ t.

This is achieved according to the invention by the fact that for thread length registration two adding, electrically resettable, with electric switches Verahlimpulse counter are provided, which alternately from one the revolutions the main shaft registering, electrically resettable, with a pre-clock and a zero switch controlling a switching device equipped Preselection counter on the pulse generator of the thread length measuring wheel schalt @ ar and through the Pre-contact can be reset.

In a further embodiment of the invention it is provided that the switching device is equipped with two switches, one of which switches alternately the pulse generator of the thread length measuring wheel on the counting magnets of the thread length register the preset pulse counter and the other at the same time change the C-e Switching over the zero setting magnets of this preselection pulse counter to the pre-contact of the causes the revolutions of the main shaft to register the preset pulse counter.

This circuit arrangement ensures that each The two preset pulse counters registering the thread length rulionde the measurement result of the previous measuring process until shortly before the start of the next but one measuring process holds and indicates that it is, however, at the time of switching when it returns is switched to the pulse generator of the thread length measuring wheel, already zeroed is, that has the advantage that not a single one Pulse from the pulse generator of the thread length measuring wheel is lost.

So at the end of each previous and at the beginning of each new counting process the preset pulse counter that registers the revolutions of the main shaft is also reset is set to its preselected output value and thus the relationship to be monitored between pile length and a certain number of traverses of the main wave is continuously maintained, it is provided in further development of the Erf @@@ ng that the zero switch of the preset pulse counter that registers the revolutions of the main shaft is switched to the zero setting magnet.

If it is further provided that the registering the thread length Preselection pulse counters have zero contacts that point to a common tool are switched, it is also possible with the counter arrangement according to the invention exceeding the permissible thread entry length per counting process, d.

If one further provides that the Mauptwellanm @@ turn to the zero switch registering preset pulse counter is another, manually resettable preset pulse counter connected, the @ en zero switch gives a switch-off signal for the machine in question delivers when a preset number of items is reached, the inventive Counter arrangement used for quantity-based production monitoring and control will.

With the aid of the drawing, an exemplary embodiment is now shown below the invention explained in more detail.

The number 360 in the preselection pulse counter Z1, however, reaches before the numbering pulse counter Z3 has counted 1500 pulses, see above a warning signal is given by closing the zero switch 9 on the warning lamp 42. Closing the zero switch 9 can also be used to switch off the machine.

However, during the course of 1490 weft, the pile length becomes of 360 centimeters is not reached, the 1490 th shot closes of the pre-contact switch 14, s @ that the reset magnet 8 of the preset pulse counter Z2 the back position causes this preset pulse counter Z2, wherein the number roller set @ on @@ ll and the number roller set 5 on the preselected number 360 is placed baz. remains set if this counter z @ before not in Betrich was.
