Abstract

PURPOSE:An automatic winder capable of selecting and feeding wound yarn depending upon degree of going up and down of a stock bar, by setting the stock bar between a position to release the wound yarn from a cradle of a bobbin winder unit and a conveyor for wound yarn. CONSTITUTION:The guide path 18 consisting of the bottom plate 19 and the side plate 21 is set between the conveyor 17 for sending wound yarn laid behind the bobbin winder unit U and the position 21 to release the wound yarn P from the cradle 1 of the bobbin winder unit U. The stock bar 24 to stop rolling of the wound yarn P once is set on the way. The stock bar 24 is a bar parrallel to the wound yarn P, and attached to the arm 25 in a shakable way round the shaft 28. The wound yarn P having bobbin diameter corresponding to degree of going up of the stock bar 24 is sent to the conveyor 17. Consequently, the wound yarn P can be selected depending upon bobbin diameter.

Description

[Detailed description of the invention] related to music.

In an automatic wine goo consisting of a large number of winding units installed in parallel, a full package wound up to a set amount is automatically doffed, and the doffed full package is transferred to the unit installed on the back of the unit. The applicant has previously proposed a device that transfers and discharges on a conveyor that extends along the line. That is, as shown in Japanese Patent Application Laid-Open No. 56-132269, a full package detached from a cradle arm is caused to fall under its own weight onto a belt conveyor provided at the back of the unit.
It is a device for transporting. In this device, the packages rolled up in each unit are automatically transferred to one side of the wine goo, so when connecting to another transfer device for the subsequent process, or manually processing the stored full packages. In some cases, it is convenient to distribute different kinds of pipe threads to separate winding units, that is, when the wine goo is divided into several unit groups and different kinds of pipe threads are wound by one automatic wine goo. The following disadvantages arise.

In other words, in the above device, when the wound packages are doffed, they are automatically conveyed one after another on a belt conveyor, so the winding time to the exit of the conveyor varies depending on the number of thread breakages. Full packages from each unit are carried out at random, and full packages of different types of yarns are mixed at the exit of the belt conveyor, necessitating extra manual sorting work.

Particularly in the case of similar threads, sorting becomes extremely difficult.

The above-mentioned disadvantage is that even if the winding start time and other timings are set apart for each group of units that are assigned to wind different kinds of pipe threads, the winding speed of each unit may vary depending on the number of thread cuts, etc. Since the times are different, the winding time in each unit will eventually become completely random and will not be resolved.

This invention also provides a method for winding different kinds of pipe threads in one automatic wine goo as described above, and the full package is completely separated into different kinds of pipe threads and transported out of the automatic wine goo. This eliminates the above-mentioned inconvenience.

Examples will be described below based on the drawings.

In Fig. 1, (b) indicates 6 parallel lines perpendicular to the paper surface.
An automatic wine goo with a winding unit (U) of 0 spindles,
Each unit (U) is equipped with a cradle part (1) that supports the winding package (P), a traversing drum (2) that contacts and rotates the package while traversing the yarn, and winds it by a known method. will be held. (3) is a well-known magazine for storing a plurality of yarns, and in order to wind up, for example, two types of different types of yarns in the 60-spindle automatic wine gourd, it is possible to manually wind up each unit. A method of inserting different pipe threads into the above-mentioned magazine (3) (for example, using a trolley-type pipe delivery device disclosed in JP-A-54-27037, for example, inserting different pipe threads into the 1st to 40th spindles) There are a semi-automatic method in which the pipe threads are automatically supplied and the pipe threads are supplied to the remaining 41st to 6th spindles manually, and a fully automatic method as described below.

That is, as shown in the schematic plan view of the bottom of the automatic wine goo (5) in FIG. A pipe delivery path (FA) in which only the pipe yarn circulates and a pipe delivery path (FB) in which only the B pipe system circulates via the pipe sorting and conveying device (5T-) are connected, for example, to a belt conveyor (4). Same as guide plate and belt conveyor (4
) and a guide plate, and the above-mentioned pipe delivery path (FA
) circulates around Yu-maru.

In the knitting group (UA) (for example, the 1st to 40th spindles), the A-pipe yarn is wound, and in the unit group (UB) (for example, the 41st to 6th spindles) where the tube yarn distribution path (FB) circulates, The B pipe system may be wound up.

The pipe (5) is taken into each unit from the pipe delivery path (FA) (FB) as shown in a perspective view in Fig. 3. (
unit (U) by guide plates (6) and (7) between
), a rotating disk (9) is provided below the passage (8), and a guide plate (11) is provided at the entrance of the passage (8) to connect the pipe and yarn intake port (12). The pipe yarn (5) is inserted into the peg tray (14) which forms a surplus pipe yarn outlet (13) and moves on the delivery path (FA) (FB) by the rotation of the rotating disk (9). What is necessary is to introduce it into the winding position (arm) directly below the unit. In addition, (15) is a turning lever for discharging an empty bobbin that also serves to position the yarn (15) introduced into the winding position (arm), and (16) is a lever for discharging the empty bobbin by blowing out compressed air to pre-dangle it into the woodwind. The nozzle is a nozzle that blows up the ends of the yarns that are being held, and the tube yarn sorting and conveying device (ST) is formed by forming circumferential grooves with different heights for each tube yarn in the disc part of the peg tray (14), A cam device that engages with the circumferential groove to allocate the destination of the peg tray, or a sensor that detects the iron ring by attaching iron rings provided at different heights for each pipe thread to the disc part of the peg tray (14). It is sufficient to use a switching device or the like that swings according to the detection signal of the sensor to allocate the destination of the peg tray.

If you use the third method above, two automatic wine goos can be connected to one
It is possible to automatically supply more than one type of different types of pipe threads, and if the number of pipe threads is further branched and increased, three or more types of different types of pipe threads can be automatically supplied.

As described above, in one automatic wine goo (B), a large number of units can be combined into two or more unit groups (UA) ('UB).
Although a method has been described in which two or more types of different types of pipe yarns are simultaneously wound with the same wine goo, any of the methods may be adopted and is not related to this invention.

Considering the following, in the wine goo with the 6o weight stand shown in Fig. 1, the unit group (
The present invention will be described by taking as an example a case in which the unit group for winding the B pipe yarn is set to unit group <UB) in which the 41st to 60th spindles are set as UA).

In other words, returning to Figure 1 again, the unit (
A conveyor bell 1-(17) for transporting a full package is disposed extending along the unit (U) on the back of the unit (U), that is, when the yarn running path side is the front side. At each unit position, there is provided a guide path (18) formed by a bottom plate (19) and a side plate (21) for guiding a full package to be removed from the cradle portion (1)'' from the removal position in the conveyor running direction. , the guide path (18) is slightly inclined toward the conveyor (F) side, and has an inclination angle e sufficient for the full package (P) detached from the cradle part (1) to roll under its own weight. (4th
Figure) (22) is a guide bar fixed along the side of the conveyor belt (17), the guide bar (22) extends across all units, and rolls on the guide path (18). It has the role of a stopper and posture control for the package placed on the conveyor belt (17), and uses the rebound when the package collides with the guide bar (22) to keep the axis of the package moving on the conveyor belt. The thread layer on the outer surface of the package and the guide bar (22) are set and fixed at a position where they are not in contact with each other during package transportation.

A stocking device (23) as described below is provided at the end of the guide path (18) to temporarily stop the full package leaving the cradle portion.

That is, the stock device (23) shown in FIGS. 4 to 6 includes a stock bar (24) that is separately provided every 10 spindles and extends along the unit, and the stock bar (24). Bearings (27) supported via brackets (25) at appropriate intervals and fixed to the machine frame (26)
a support bar (28) supported by the bracket (28);
5), the stock turning fluid cylinder (31) is connected to one of the sidemost brackets (25) via a lever (29) that is integrally fixed thereto.

That is, in this example, since the winding unit has 60 spindles, six units of the stock device (23) having the same structure are consecutively arranged as shown in the sixth figure.
Hereinafter, one set of stock devices will be explained in detail.

That is, a support bar (28) is attached to the lower end of the connecting rod (33) connected to the piston rod (31a) of the fluid cylinder (31) which is supported (32) on the machine frame (26).
The lever (29), which can be pivoted around the lever, is pivotally mounted, and the stock bar (24) is
rotated between the solid line position and the two-dot chain line position in Figure 4, and the above positioning was achieved! 4. , positioning is possible.

It is provided at a position where the circular arc locus (34) of the center of the cupper (24) passes (Fig. 4).

Furthermore, the length L) of the guide path (18) corresponds to the separation position of the full package from the cradle section and the conveyor (17).
In between, there is no interference between the package (P) at the above position, and at least one full package can exist between both package (P) positions, and the stock bar (24)
It is advantageous for the length to include a distance sufficient to prevent the stock bar (24) from interfering with the packages (P) on the conveyor (17) when the stock bar (24) rotates.

Note that the doffing of each unit above is carried out using the traveling body (3) shown in Figure 1.
5). That is, the traveling body (
35) is suspended via wheels (37), and the traveling body (35)
) is equipped with a doffing mechanism (not shown) to remove the full package (P) from the cradle part (1), and the empty bobbin stored in the traveling body (35) is supplied to the cradle part to restart winding. is now being carried out.

When winding is performed at a certain point and a certain amount of yarn layer is formed,
By the doffing operation described above, the full package is separated from the cradle section and temporarily stopped at the position where the guide path (18) is located and the stock bar (24) is provided at the end.

In other words, as mentioned above, in each winding unit, the time required to complete the winding varies depending on the number of thread breakages, etc., and even if winding is started at the same time, the doffing time differs for each unit. Packages doffed at different times (
P) are all stopped by the stock bar (24) regardless of the unit (U) or yarn type. Therefore, after a certain period of time, the stock bars (24.1) to (24.4) of the unit group (UA) will contain the full package (pA) of A-pipe yarn, and the stock bar (24.1) of the unit group (UB) will have a full package (pA).
4, 5 x 24, 6) is a full package of B tube yarn (PB
) is stopped and temporarily stopped (as shown in Figure 6), but the stock bars (24.1) to (24.6) are rotated according to the following time schedules, respectively. A full package (PA) of A-pipe yarn and a full package (PB) of B-pipe yarn are carried out at different times.

That is, each stock 2 bars (24.1) to (24
・Solenoid no. of the fluid cylinder (31) in 6).

'f(SV) is connected to the circuit shown in Figure 7, and by switching each snap switch (Sl) to (S6), it is connected to either of the parallel circuits (a) and (b) connected to the power supply. In this example, the solenoid pallet X corresponding to the stock bar (24.5) (24.6)
(SV) is connected to the circuit (b) side. Then, the parallel circuit (a) (one includes a timer (TMa)
Switches (Sa) and (Sb) that are turned on and off at fixed time intervals by (TMb) are interposed, and each timer (T
Ma) (TMb) is set to a time t that is about 20% shorter than the average winding time T by the automatic winder, and the time-up timings of the timers (TMa) and (TMb) are shifted by dt dark time (for example, 5 minutes). It is set to do so.

Therefore, for example, if the average winding time T is 60 minutes,
Assuming that the opening time interval t of the stock bar (24) is set to 50 minutes and the delay time dt is set to 5 minutes, the time chart for each stock bar (24.1) to (24.6) is shown in Fig. 8. The full package (PA
) is (TA), the stock bar (24・1) ~ (
24.4), and are immediately (within at least 5 minutes) carried out by the conveyor (17), and after the carrying out is completed (dt from the time point (TA)
time later) When the full package (PB) of the B tube yarn of the unit group (UB), which was stopped by the stock bar (24.5) (24.6), reaches (TB), the stock bar (24.5) (24.6)
・5) (24.60) They are released all at once by the turning movement and are immediately carried out on the conveyor (17).

The shift dt between the dime-up timings of the timers (TMa) and (TMb) is varied and set depending on the speed of conveyor (17).

Furthermore, according to the time chart in Fig. 8 above, the first turn (T
A) is before the average winding time T has elapsed, so it is expected that only a small number of full rolls/N6 cages that were wound very quickly will be taken out, but from the second and subsequent turns (TA), the average About 40 full packages (PA) are taken out all at once, and when the stock bar (24.5) (24.6) turns (TB), an average of about 20 full packages (PB) are delivered each time. are carried out all at once.

In addition, each full package (PA) (PB) that was carried out
The overhead conveyor (43) is shown schematically in FIG. ), or an end feeler (not shown) may be provided at the end of the conveyor (17), and a notification device such as a lamp or an alarm connected to the end feeler may be used to alert the operator to a full book. The operator is notified of the delivery of the package (PA) or (PB) and its arrival at the end of the conveyor (17), and the notified worker transfers the package (PA) to a different container for each yarn type at the exit position of the conveyor (17).
Alternatively, (PB) may be received, and in any case, the full packages (PA) and (PB) of different types that have been stopped by the stocking device (23) are different in time and are not of the same type. Because they are carried out all at once,
Packages of different types are not randomly mixed together at the exit of the conveyor, and later sorting work is omitted.

Furthermore, in the above example, the stock device (23) is provided independently for every 10 spindles, and the snap switches (Sl) to (S6)
Each stock bar (24・1) to (24
・Since the operation timing in step 6) can be easily switched between using the timer (TMa) and using the timer (TMb), the lot size of each pipe yarn changes and each unit group (UA) If you want to change the proportion of (UB), for example, change the 1st to 30th spindles to a new unit 7
1 (UA), and the 31st to 60th spindles are a new unit group (
tJB), in the above example, stock/<
- By simply switching the snap switch (S4) corresponding to (24.4), packages that are stopped by the stock bar (24.4) can be newly ejected at the timing of (TB), making it easy to change the relevant unit group. Can correspond to

In addition, when winding three or more types of different types of pipe threads, for example, the 1st to 20th spindles are used as the unit group for winding the A pipe thread, and the
The 1st to 50th spindles are the unit group for winding the B tube yarn, and the 51st to 50th spindles are
In cases where 60 spindles are used as a unit group for winding C pipe yarn,
The power supply circuits (a) and (b) are further branched to form three parallel circuits, and each stock bar has an operating fluid cylinder (31).
Connect the threaded connection corresponding to the snap switch (Sl) (8
2XS3) to circuit (a), snap switch (54)
(S5) is connected to the circuit (b), and the snap switch (S6) is connected to the newly branched circuit, so that the stock device (23) corresponding to each unit group can be connected in parallel with each other caused by different timers. The rotation movement may be made according to the determined operation timing.

In any case, as is clear from the above description, in the doffing system of the present invention, in an automatic winder in which a large number of winding units are arranged in parallel, the doffing system extends along the units and places a fully wound package on it. A stocking device for temporarily stopping a full package is provided in the middle of a package guide path provided between a traveling conveyor and a position where a full package leaves the cradle portion of each winding unit. Each unit group of the automatic wine goo divided above can be operated independently.Thus, the doffed packages temporarily suspended in the stocking device can be individually released for each unit group. This allows the packages rolled up by each unit group to be carried out without mixing them up.
