Description

[Detailed Description of the Invention] This invention relates to a counting and display device for counting and displaying the number of yarn cuts by a slab catcher in an automatic yarn winding machine.

When rewinding spun yarn into cheese using an automatic winding machine, yarn defects such as slabs present in the spun yarn are cut and removed by a slab catcher installed in the winding machine. The number of times the yarn is cut by the slab catcher for each book is counted and displayed by a counter and a lighting display device provided for each winding spindle.

An embodiment of this invention will be described below with reference to the drawings.

As shown schematically in FIG. It has a well-known configuration in which it is rolled up as a cheese 8. Further, when the tube yarn 2 is wound up, it is automatically replaced with a new tube yarn by a tube exchange device (not shown), which also has a well-known configuration. In such an automatic yarn winding machine, this invention extracts signals from the yarn cutting operation of the slab catcher and the yarn changing operation (for example, rotation of the yarn case) of the yarn changing device, and generates signals as shown in Fig. 2. It performs signal processing.

That is, in FIG. 2, a pulse is generated in association with the yarn cutting operation of the slub catcher, and this pulse is transmitted to the side housing 9 of the winding spindle (FIG. 1).
The signal is applied to a counter 20 housed in an amplifier case 10 (FIG. 1) provided above the counter 20.
The count of the counter 20 is incremented by one.
The signal generated in association with the bobbin replacement operation accompanying the winding up of the bobbin is sent to the counter 20 and used to reset the count of the counter 20.

That is, the counter 20 counts the number of times the yarn is cut by the slab catcher between exchanges of the yarn.

The output of the counter 20 is applied to a setting switch 21 from time to time. The setting position of the setting switch 21 can be freely selected. The setting position of the setting switch 21 corresponds in stages to the number of thread cuttings, and the number of thread cuttings corresponding to the setting position is the number of thread cuttings corresponding to the setting position.
2 (Figure 3). For example, if the number of thread breaks is less than 2, the lamp will not light up, but if the number of thread breaks is 2 or more, the lamp will turn on and turn green, if the number of thread breaks is 4 or more, the lamp will turn yellow, and if the number of breaks is 6 or more, the lamp will turn yellow. A display method that appears red is adopted.

Note that the stop weight signal 25 can also be extracted from any output of the setting switch 21.

FIG. 3 is a detailed circuit diagram of the circuit shown in FIG. 2, in which the redo relay 13 is connected to the counting input terminal of the counter 20 via a waveform shaping circuit 30. Further, a switch 31 which is turned on when the yarn is replaced is connected to the reset input terminal of the counter 20 via a waveform shaping circuit 32.

Each output terminal of the counter 20 is connected to a setting switch 21, so that the count value of the counter 20 can be taken out at will according to the setting position of the setting switch 21.

The output terminal of the setting switch 21 is the transistor 2
The emitters of the transistors 26 and 27 are connected to two color light emitting diodes 23 and 24, green and red.

Each light emitting diode 23, 24 is attached to the housing 9 (FIG. 1) of each winding weight, so that an operator or the like can identify them when visiting a plurality of winding weights.

In the above configuration, when one thread is cut by the slab catcher, the reed relay 1
3 is turned on, a pulse is applied from the waveform shaping circuit 30 to the counter 20, and its contents are incremented by one. When one more thread is cut, the count of the counter 20 increases by one in the same way.

When the content of the counter 20 becomes, for example, a setting value "2" or more of the setting switch, the transistor 26 is turned on and the green light emitting diode 23 is turned on. When the content of the counter 20 exceeds the setting value "4" of the setting switch, both transistors 26 and 27 are turned on, and both the green light emitting diode 23 and the red light emitting diode 24 light up, giving a yellow color.

Furthermore, when the content of the counter 20 becomes "6" or more, the transistor 26 is turned off and only the red light emitting diode 24 is lit.

When the unwinding of one yarn is completed and the yarn is replaced, the switch 31 is turned on and the counter 2 is turned on.
0 is reset in preparation for the next yarn count.

With respect to the other winding weights, the number of yarn breaks by the slab catcher is counted and displayed for each tube yarn by the same device as in FIG. 2 or 3.

As mentioned above, this invention is designed to count and display the number of thread breaks by the slub catcher for each pipe thread in an automatic thread winding machine, so it is possible to count and display yarn defects such as slabs that exist in each pipe thread. This is a truly useful idea, as it not only provides useful process control information for previous processes such as the spinning process, but also provides information on the efficiency of the automatic thread winding machine and the quality of the wound cheese. It should be said.
