Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a package in a spinning and weaving apparatus consisting of a large number of spinning units (g units) arranged in parallel and a running body such as a yarn splicing cart that runs 7d to the large number of spinning units. The present invention relates to a yarn winding amount management device.

In a spinning device with a large number of spinning units arranged side by side as described above, even if spinning starts at the same time, problems such as yarn breakage (
2. Therefore, the winding packages of all units are never rolled up at the same time. Therefore, if it is attempted to manage the raw frying of the package using the container of the package, it is necessary to provide a package diameter detection device in each unit.

However, in the case of doing the above, the cost of installing a detection device in each unit increases, and if the diameter of the package to be doffed is changed, the detection device for that package diameter must be readjusted for all units. This required a lot of manpower and effort.

Therefore, the present invention includes installing an inclination angle indicating piece of the cradle in the cradle of each spinning unit, and detecting the inclination angle indicating piece on a traveling body that is running in a manner consistent with a large number of spinning units. The above-mentioned drawbacks are solved by providing a cradle inclination angle detecting means that issues a start/stop signal.

Spinning and winding can be separated.

In this example, the yarn splicing cart (1G) is provided with means (51) for pushing down the arm (38) that moves downward by -L.
The yarn splicing cart (16) is spun by the fat-separating device (26).

It looks like this.

Next, the spinning stop device of the spinning unit (2) will be explained.

In FIG. 5, C52)l and the bank roller (3)
The back roller (3
) and the bank roller (3) are connected via an electromagnetic clutch (not shown).

(54) is a drive line shirt I. which is connected with the rotation I'1IllI (53) by a bell I- (55).

(56) is a stop pin that plunges into the ratchet gear (52) marked -1- to stop the ratchet gear (52), and the stop pin (56) swings its base end into the machine frame (14). It is supported by a freely supported crank & (57), and can be moved by the rotation of the crank plate (57). It supports a connecting rod (59) that connects with the block (58).

A suction plate (61) is provided in the middle of the connecting rod (59), and when the suction plate (61) is attracted to or separated from the solenoid (62) fixed to the machine frame (14), The connecting rod (59) is held or made to be freely movable downward, so that the rotation of a rotation block (58), which will be described later, can be restricted.

The pivot arm (66) of the thread cutter (65) is connected to one end via the connecting rod (64), and the swing arm (66) of the thread trimmer (65) is connected to the connecting rod (64) at one end. A manual push button (68) is connected via a rod (67).

Further, (69) is the bank roller (3) and the rotating shaft (5:

5) - is constantly biased in the counterclockwise direction,
When the slab catcher (11) detects a slab or yarn breakage, the solenoid (62) is demagnetized by the detection signal from the slab catcher (11), and the suction plate (61) is moved from the solenoid (62). The rotation block (58) is rotated counterclockwise by the spring (71), and the stop pin (56) rises twice and engages the ratchet gear (52) to stop the back roller (3). The actuator (69a) falls into the recess of the cam (58a), the micro switch (69) is turned off, and the electromagnetic clutch between the back roller (3) and the rotating shaft (53) is turned off, and the flybar supply is stopped. Stop at roller (3) part 12
When the spinning is stopped, J2 is on its way.

When a slab is detected, the cutter (65) is activated by the rotation of the rotation block (58), so the thread (
Y) is cut there, and the thread part that connects the slab is back''
- The yarn is wound on the thread (12), but the later thread is spliced r3r'

L, the stop bottle (5) hardens, the electric clutch moves back, the 1-RA (3) rotates, the spinning continues for 111 minutes, and the yarn (Y) catches the slab catcher (11). As the engine starts running 1j, the solenoid (ti2) is output and energized and attracts & (61).

Next, I will explain 1'+: III.

In other words, the yarn (Y) spun through the draft device (7) and air injection nozzle (8) as described in 1- is passed through the nip roller (9) and the slab catcher (11) *;'p'

21) increases in slope.

Therefore, the above-mentioned yarn splicing trolley (16 months old, 1 digit proximity switch (23)) is moved to the appropriate pan cage (
12) If you align it with the diameter scale position, the cradle (
21) is tilted significantly and the head portion (22a) of the tilt angle indicating iron piece (22) attached to the cradle (21) reaches a predetermined position, that is, the package (12) has reached the predetermined winding diameter. If it is 1 hard, the relevant spinning unit (2)
Proximity switch (2

Kick out the extruded plate (72) (Fig. 6), which also serves as a display plate provided below the slab catcher (11) in (2), forward. Since the washer (74) is fitted and there is no friction, the yarn extrusion gear (24 month nil) provided on the traveling trolley (1 (3)-1) extrudes the thread instantly. Even if the yarn splicing table 1↑!, (!6) has gone too far, it will maintain its extended position.

Then, when the thread (Y) is pushed out from the slab catcher (11) by the push-out plate (72) which has been pushed forward as described above (dashed line in Figure 5), the slab catches as described above. The solenoid (62) is demagnetized by the - signal from the catcher (11), the suction plate (61) is separated, and the rotating block (58) rotates, spinning.

The output will be stopped. Further, in this embodiment, the above-mentioned cutting device (26) is activated by a signal from the slab catcher (11).

・The package (12) detects units (2) that have reached the set diameter one after another and performs the above operation, so each unit (2) 1U is equipped with a Even if it is not provided, the spinning of the unit (2) can be reliably stopped by accurately detecting that the package (12) has reached full capacity.

In addition, for each spinning unit (2), the inclination angle indicating iron piece (
22) to the cradle (21) (=1 position), small variations in the pan cage diameter for each unit (2) can be eliminated.

As described above, spinning is stopped and the knot cage (1

To perform the above operation manually, press the push button (68) of the spinning stop device and the spinning will be opened as described above. 26).

In the above embodiment, the yarn extrusion kicker (24) protrudes in response to the spinning stop signal from the proximity switch (23).
The spinning was stopped by demagnetizing the solenoid (62) by extruding the yarn (Y) in the slab catcher (11), but other relay means, such as the spinning Using a light emitting device that emits light in response to the spinning stop signal and a light receiving device installed on the machine frame (14) side, the spinning stop signal from the proximity switch (23) with -1'' is sent directly to the solenoid (62) as a degaussing command signal. The traveling body provided with the proximity switch (23) is not limited to the yarn splicing cart (16), but can also be used with a large number of spinning units (2).
(2)...If it is a running body that travels in a row, it may be an automatic doffing device, etc., or it may be a fluff removal blower device, etc. It is also possible to provide a new rail 7 and run a dedicated running body equipped with a detection means.

As is clear from the explanation below, the winding amount management device of the present invention includes a cradle inclination angle indicating piece 11 attached to the cradle of each spinning unit, and a device that runs along a large number of spinning and bonding units. Since the traveling body is provided with a cradle inclination angle detection means that detects the inclination angle indicator piece and issues a spinning stop signal, it is not necessary to install a package diameter detection device in each of a large number of spinning units. Accurately detects when the package diameter of the spinning unit reaches a predetermined diameter,
Spinning is stopped, that is, the winding amount is appropriately controlled.

Further, the pan cage winding diameter of all the spinning units can be changed simply by adjusting the inclination angle detection means provided on the traveling body, which is extremely efficient.
