Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to information instruction adjustment for reeling in an automatic reeling machine.

(Prior art) The function of automatic yarn reeling machines, which started from multi-filament reeling machines, has shifted from fixed position reeling to constant fineness reeling. The instruction is to stop the thread tension in a small frame.

The welding instruction, as shown in Figure 1.5, is to instruct the fineness limit, and the frictional resistance of the yarn when it is inserted into the slit 3 during reeling is the set load of the sensor 2. In other words, when the sensor 2 turns downward due to the search lever 8
This is the same as when the load lever 6 is operated in the downward direction of the sensor 2 in synchronization with the operation of.

The retrieval lever 8 is connected to a forward lever 14 that is "operated intermittently by the cam 19 of the drive wheel" and swings back and forth under the pin 4 of the sensor 2, so that the 7th part of the lever touches the pin 4. We are giving instructions to attach the fish on the condition that it will be caught.

(Problem to be Solved) When the two moving parts of the search lever 8 collide with the pin 4 of the sensor 2, the force of the search lever 8 to move further causes the detection indicator bar 18 to move forward.
We are pulling up and performing splicing.

For this reason, the search lever 8 and the pin 4 of the sensor 2 are severely worn, and after further collision, the search lever 8 stops and the thread remains in the slit 3 of the sensor 2 for a long time until the welding is completed. This results in accidents such as garbage clogging.

The present invention cuts off the contact between the search lever 8 and the pin 4 of the sensor 2, eliminates wear, and makes the movement of the sensor 2 only due to the original relationship between the frictional resistance of the thread and the eccentric load, increasing sensing accuracy. , solenoids 20 and 22 are used to instruct the welding and stop of the small frame.

Furthermore, information on granulation and number of knots is proposed as reeling information.

(Means for solving problems) This will be explained with reference to FIGS. 1 and 2.

The sensor case 1 has a sensor 2, a slit, and a load receiver with a pin 5.
Of the structure near the current sensor equipped with a load lever 6 and a search lever 8, the search lever 8 in Fig. 3 may be removed, or the pin 4 may be discarded or shortened. ,
A photosensor 11.12 is provided as an example of a single actuation reactant that breaks contact with the search lever 8.

This will be explained with reference to FIG.

Of the current structure in which the front moving lever 14 welding instruction lever 16 is provided on the acceleration wheel cam 19 and the welding instruction rod 18 is used to issue welding instructions, the welding instruction rod 18 is separated and a solenoid 20 is provided.
Although not shown, a sensing cycle extraction device is provided on the drive wheel camshaft.

A one-shot solenoid 22 is provided on a lever 21 of a stop lever.

A control device 23 is provided near the sensor case 1 or in a separate location for each component.

(effect) The "load lever" will be explained with reference to FIG.

An actuation reactor is provided which operates when the load lever 6 lifts the load receiving bin 5 of the sensor 2 in a counterclockwise direction about the load lever shaft 7.

The actuating reactant is the photosensor 11.12 in FIG.
In Fig. 6, lla transmission type photosensor, in Fig. 7, 1
1c and 12c lead sensors and magnets.

Of course, a reflective photosensor that utilizes reflection from the plate-like surface may also be used.

The "search lever" will be explained with reference to FIG.

An actuation reactor is provided at a position that senses when the search lever 8 turns clockwise about the search lever shaft 10.

The actuating reactor is the transmission type photosensor 11.1 in Figure 3.4.
2, and in FIG. 6, the leet sensor llb, 12b,
and a magnet, which is a transmission type photosensor 11d in Fig. 7, but the mounting position is limited to this. Drive wheel cam 19
It may be provided at any position where it operates during previous searches.

"Common use of load lever and search lever" The photosensors 11 and 12 are located at a position that satisfies the sensing positions of the load lever 6 and the search lever 8 at the same time, and the movements of both are similar to IL and 12 in FIGS. 3 and 4. show.

"Current welding instruction mechanism" FIG. 5 is a drawing showing the relationship between the area around the acceleration wheel cam 19 and the area around the sensor case 1.
4 by a rod, and the fibrillation lever 14 corresponds to "the position of the welding instruction lever shaft 17 being moved up and down by the operation of the drive wheel cam 19" with the movement lever shaft 15 as the center. Operates left and right.

At this time, when the search lever 8 hits the pin 4 of the sensor (as shown in Fig. 1.2), the fibrillation lever 14 stops moving, so the position of the welding instruction lever shaft 17 stops and continues upward. The force 1 moving forward causes the welding instruction lever 16 on the back side of the fibrillation lever 14 to pull up the welding instruction rod 18 with the welding instruction lever shaft 17 as its center.

"Gluing Instruction" The explanation so far has been about the welding instruction structure of the currently used automatic yarn reeling, and the present invention is to connect the currently used welding instruction rod 18 to the welding instruction lever 16.
The welding instruction solenoid 20 is connected to the welding instruction solenoid 20, and the welding instruction rod 18 is pulled up based on instructions from the control device 23.

``Cycle timer'' The fineness sensing mechanism is ``intermittent search and one cycle in which the yarn passes through the slit twice to prevent clogging of the slit.''
In order to obtain a 4-second cycle timer, the drive wheel camshaft is rotated, and since one revolution is processed as one cycle (not shown in the figure), a cam is provided on this shaft to obtain a cycle signal.

"Load lever sensor time chart" ■Chapter 6.7, 8
This will be explained using figures.

Before the cycle starts, the load lever 6 moves the sensor 2 around the load lever shaft 7 due to the load applied to the load lever hole 6a.
Since the load receiver applies an upward force to the bottle 5, the sensor 2 is facing downward and the load lever 6 is facing upward.

The load lever 6 is separated from the slit of the photosensor lla, and the photosensor lla is installed at a position where a truth value is output to the control device 23.

If the truth value is H at this time, it indicates that the sensor 2 is facing upward, so A = the thread is cut off below the sensor slit, and the thread above the slit touches the sensor. It is pulled upwards.

B = The sensor is not in the designated position, or is abnormally facing upwards or cannot move.

Due to an accident such as this, the small frame was stopped and one rework was ordered.

■The next operation will be explained with reference to FIG.

When the search starts, the thread is inserted into the slit 3 of the sensor 2, so the shock of insertion and frictional resistance cause the sensor 2 to face upward, except in the case of ultra-fine threads, so the light from the photo sensor lla is The output shows the truth value H.

■After that, if the fineness of the thread is thicker than the fineness limit, the truth value H. If it is thin, the sensor 2 changes downward and becomes the truth value, so the broken line indicates that the truth value changes depending on the fineness limit.

■The search operation in current automatic reeling machines involves passing the yarn through the sensor slit to prevent it from clogging with dust, so the sensor 2 turns downward and the truth value returns; however, if the truth value H A, light cutting can be predicted due to dust clogging of the slit.

B. Previous processing = When searching, the thread is supposed to enter the slit, but in the case of extremely thick thread, it cannot enter the slit and the thread runs, so the sensor is pointing upward.

etc., so the small frame stop instruction is given.

(2) Since the cycle ends after the cycle is returned and the page is inserted, the sensor 2 repeats up and down one more time, and the truth value becomes L-H-L.

If there is no change in the last truth value, the previous A accident can be predicted, so an instruction is given to stop the /h frame.

With the above operation, the output from the photosensor lla becomes the time chart of A=load in FIG.

This will be explained with reference to the search lever sensor time chart J, Figure 5.7.8.

Before the start of the cycle, the search lever 8 and the photosensor 11d are in the positional relationship shown in FIG. 7, and the search lever 8 is placed in the slit of the photosensor to output a truth value.

When the activation lever 14 pushed out by the rotation of the drive wheel cam 19 advances the search lever 8 one step clockwise, the thread is inserted into the slit 3 of the sensor 2.

The search lever 8 moves away from the slit of the photo sensor lid and becomes the truth value H shown in FIG.

After T seconds, when the forward moving lever 14 advances further, the thread passes through the sensor slit, but the truth value is at that point, and after 12 seconds the retrieval lever 8 returns counterclockwise - T seconds later, it returns to the original position. When it returns to the position, the truth value returns, so in the time chart of FIG. 8, B=search.

This will be explained with reference to FIG. 9, "Time Chart of Timer 2.3."

The cycle timer described above is used as an intermittent sensing mechanism in current automatic machines, and the rotation of the drive wheel camshaft is variable, allowing the intermittent time to be adjusted as desired. This must be synchronized.

Therefore, in the cycle, the time chart T1 is obtained as an electric signal from the acceleration wheel camshaft, and the four stages of cycle start, search (1 to 1.5 seconds), slit passage, and page insertion are output as pulses T1. .

T2 is obtained by converting the counter of T1 into a binary number counter using a flip-flop, and T3 is obtained by further converting the counter into a binary number counter.

(Example) The usage of the sensor and timer of the patent claim @(A) of the present invention will be explained with reference to FIG. 9.

The time chart is composed of four sets: A = load and T1 to 3 = timers, and the truth value is determined by the progress of each.
The yarn reeling condition is determined by classifying the combinations of truth values input into the program in the control device as shown in the table below in FIG.

At the start of the cycle timer = 1, immediately after = 2, search = 3,
The stages of slit passage = 4 and slit insertion = 5 are determined in synchronization with the operation of the drive wheel cam, and when these truth values are sorted out, progress is good = OK, small frame stop = stop, and 3 stages of welding
classified into types.

As mentioned above, small frame stoppages are classified into various causes, but as shown in the table below the drawing, the truth values of the stoppages are all different, so it is useful to understand which cause of the stoppage is caused and to consider subsequent processing. It is something.

When the small frame is decided to stop, the small frame will be stopped automatically.

A stop command is given, the count is made, and the cumulative number becomes the data that determines the quality of the thread.When deciding whether to weave, the welding operation must be started immediately.
It is possible to correct and instruct the graining, and by indicating and recording the number of welding requests as the total number per set of automatic machine, it is useful for determining the operation of the automatic machine, and the number of welding requests is an indicator of the quality of the yarn. The most closely related and continuous attachment requests are those that can predict some sort of accident.

The usage of the sensor and timer according to claims (A, B) of the present invention will be explained with reference to FIG.

The time chart is made up of four sets: A = load, B = search, and T1-2 = timer.Compared to Figure 9 in the previous section, timer T3 has been changed to the output of the search photo, and regarding the data. It's the same.

The usage of the shared sensor and timer according to claim (3) of the present invention will be explained with reference to FIG.

The time chart of the photosensor that satisfies the load and search levers at the same time is indicated by F, and T1-3 = timer 4.
It is composed of groups.

Although the truth tables for the three categories of OK, stop, and welding are different for the three sets of time charts above, the classification based on the 4Mi combinations is the same, so the program for processing the given data and giving instructions is They are the same, and can be solved by incorporating a simple IC.

(Effect of idea) The present invention has the following effects.

1. Since instructions for splicing and malfunctions can be recorded, it is easy to manage and treat the cocoons and thread during reeling, and the quality of the thread can be guaranteed.

2. Since there is no contact between the search lever and the sensor, sensing accuracy can be increased and the service life can be extended.

Information on cocoons and threads during reeling such as tree 3, extra-large thread, ultra-fine thread, light cutting, and abnormal accidents can be obtained.
