Description

[Detailed description of the invention] The state in which the splicing mechanism operates in a reeling machine includes boiled cocoons and
It contains a lot of useful information on the reeling process.

In other words, there are effective cocoons and invalid cocoons in the number of cocoons, and invalid cocoons occur when there are many uncocooned cocoons or cocoons with poor cocoons in the cocoon feeder that circulate within the reeling machine. If the number of invalid coons increases due to a small number of cocoons or the cocoon threads are not properly transported to the cocoon collector, the number of cocoons per unit time will inevitably increase.

In this way, the frequency of the cocooning mechanism operation increases when there are few waiting cocoons in the cocoon feeder, or when there is something abnormal between the cocoon feeder and the cocoon collector and invalid cocoons occur frequently and become large. And, due to poor unraveling of the cocoons that are being reeled, the frequency of droplets increases.
The frequency may increase in order to maintain the desired fineness of the raw silk yarn.

When counting the number of welds and the number of effective welds, the conventional method based on the operator's vision can only handle two or three welds at most, and requires strict attention from the operator. Continuous measurement is not possible due to the required
It is not possible to accurately grasp and manage the status of the process.

In addition, if the frequency of invalid welding increases, especially if invalid welding continues continuously, yarn unevenness will occur in the raw silk threads, causing a significant deterioration in the quality of the raw silk.

On the other hand, in order to detect whether or not the cocoon has been effectively welded by driving the welding rod, there is a measuring means similar to the detection confirmation act that relies on the visual sense of the operator. Focusing on changes in the fineness of raw silk and changes in reeling tension due to being spliced into rows, the state in which the splicing rod is driven and immediately after that the fineness of raw silk increases or the reeling tension increases is considered to be effective splicing. If no change is found in the raw silk fineness or reeling tension even though the welding rod has been driven, it is possible to consider the method as invalid welding, but assuming an actual reeling process, these detection mechanisms It is extremely difficult from a management standpoint to install a large number of devices together and measure them continuously.

In the present invention, the number of welding times, the apparent effective welding number (hereinafter, "apparent effective welding") is simply "
The effective cocooning rate (referred to as "effective cocooning"), the effective cocooning rate, and the frequency at which invalid cocooning occurs are automatically and accurately measured, and the condition of the cocoons in the cocoon feeding machine and the cocoon transfer from the cocoon feeding machine to the cocoon gathering machine are measured automatically and accurately. Its purpose is to provide a device for estimating the state of the cocoon, the unraveling property of the cocoon, the unevenness of the raw silk yarn, etc., and obtaining information useful for controlling the process. A welding signal circuit, in which a differential circuit and a comparator are connected in sequence, is connected to the welding operation sensor provided for each yarn in a multi-thread reeling machine, and an integral circuit, a comparator, a differential circuit, and a comparator are connected in sequence. A continuous multi-time coupling signal circuit in which an effective coupling signal circuit, an integrating circuit, a comparator, an off-delay circuit, a differentiation circuit, and a comparator are sequentially connected is connected, and the said coupling signal circuit of each circuit, the apparent effective coupling signal circuit, and The continuous multiple welding signal circuits are each connected to a common counter for each welding, and the apparent effective welding rate is calculated from the count values of the welding signal and the apparent effective welding signal for a certain period of time or for each set number of weldings. The present invention is characterized in that it is equipped with a computing unit that performs the following operations.

Embodiments of the present invention will be described below with reference to the drawings.

In the block diagram of Figure 1, A, , A2・11・A
Numeral n designates a welding operation detection sensor provided in each of the reeling machine's multiple cords, which is composed of a microswitch or a proximity switch, etc., for detecting the operation of the weaving mechanism as a pulse signal.

EC1, EC2... Ecm is an electronic circuit connected to a welding operation detection sensor provided for each cord, and serves as a welding signal circuit that is determined by a differential circuit B, a comparator C, and a buffer D. , an effective combined signal circuit consisting of an integrating circuit E, a comparator F1, a differentiating circuit G, a comparator H and a buffer It consists of a joint signal circuit.

O is the output terminal U1, U2 of each joint signal circuit.
・・・・・・Electronic counter connected to Un, P is the output terminal of each effective connection signal circuit ■1, v2...
An electronic counter connected to Vn, S is an electronic counter connected to output terminals W1, W2...Wn of each continuous multi-time connection signal circuit, and these counters 0, P, S
are interlocked with the repetition timer T, respectively.

Q is a divider and R is a display.

Next, to explain its operation, the output signal of the welding operation detection sensor A1 shown in FIG. , obtain the signal shown at the beginning of Figure 2.

This is because if the welding signal shown in Fig. 2A is measured simultaneously from multiple corresponding other strings, it may be input to the counter superimposed with the detection pulse signal of the other strings and not be counted as a correct value. This converts it into an instantaneous pulse signal.

Next, as shown in FIG. All signals are converted into such instantaneous pulse signals.

The signal pulsed by the comparator C is counted by an electronic counter O via a buffer D which is connected to an OP amplifier.

On the other hand, the effective number of weldings and the frequency of consecutive multiple weldings are counted by passing the pulse signal from the welding signal detection sensor A1 through an integrating circuit E consisting of an OP amplifier, a capacitor, and a resistor. The voltage signal is integrated as shown in FIG.

This waveform shows an effective coupling, and as shown in the waveform conversion forms from E to G in Fig. 2, the rising part of the pulse waveform in Fig. 2 E is converted into an instantaneous pulse signal, so the differential The waveform differentiated via circuit G is sent to comparator H.
, a voltage signal higher than the voltage setting level Z is determined and converted into a pulse signal.

Thereafter, it is counted as the effective number of times in an electronic counter P via a buffer I constituted by an OP amplifier.

The frequency of continuous multiple coupling occurrences is determined by first using the signal from the integrating circuit E,
In other words, a comparator J that can vary the voltage setting level Y depending on the number of consecutive connections aimed at the signal shown in FIG.
As a result, a voltage higher than the voltage setting level Y is pulsed.

Since this pulse waveform may have two or more pulse waveforms as shown in Fig. 2H, it is converted into one pulse via the off-delay circuit K (Fig. 2).Next, this pulse waveform In order to extract only the rising portion of the voltage, a signal higher than the voltage setting level Z is determined by a comparator M via a differentiating circuit L (FIG. 2), and is converted into an instantaneous pulse signal (FIG. 2).

After that, through the buffer N which is monitored by the OP amplifier,
It is accumulated on an electronic counter S as the frequency of occurrence of continuous multiple welding.

The electronic counters o, p, s are linked with the repeat timer T,
After the arbitrarily set time has elapsed, a divider Q calculates an effective welding rate, which is a percentage of the effective welding count to the welding count, from the counts of the electronic counters 0 and P, and displays it on the display R.

It should be noted that the electronic counter O can preset the number of arbitrary weldings to be measured, and it is also possible to calculate the effective welding rate when O reaches the set value.

The operations of the other attachment operation detection sensors A2 to An and the electronic circuits EC2 to ECn connected thereto are also the same as described above.

In addition, in the automatic reeling machine, the activation timing of each welding mechanism is shifted based on four weaves as a unit, so if the number n of welding signal detection sensors A1 to An is within 4, the welding signal is detected. When attaching sensor A to the welding rod, the welding signal detection sensors A1 to A4 may be attached to the same position on the welding rod, but if n is 4 or more, the welding signal detection sensors are attached to the welding rod every fourth. It is necessary to slightly shift the position of sensor A, and to shift the timing of the rise of the welding signal pulse a little bit every four times.

As described in detail above, according to the present invention, it is possible to measure the number of times of weaving, the effective number of times of weaving, the effective welding rate, and the frequency of occurrence of continuous multiple weaving in multiple yarn reeling machines, so that it is possible for the yarn reeling manager to In this case, the number of effective splicings indicates the cocoon unraveling performance, the effective splicing rate and the frequency of consecutive multiple splicings indicate the state of the cocoon in the cocoon feeder, the cocoon feeder take-out efficiency, and the raw silk. It is possible to estimate the state of occurrence of thread spots in the rows.

Therefore, it is possible to control the reeling process in an optimal state using these data as feedback information, and this device has the advantage that it can also be applied as a detection sensor in an online control system using a computer.
