Abstract

PURPOSE:To improve the availability of winder by moving a bobbin failed of pick finding immediately from pick finding unit through feedback path to pick finding station then executing pick finding again and reducing supply of misbobbin. CONSTITUTION:A bobbin failed of pick finding is immediately returned through the stations G, H to receiving station A without delivered from the station F onto a conveyor 87 and controlled to be applied with pick finding operation again prior to the bobbin on the conveyor 87. Upon reaching of failing times of pick finding of specific bobbin to setting time, it is delivered from the station F onto the carrying path 7 without functioning a movable guide 27. Since the bobbin will circulate along a rotary board and applied with pick finding operation until mis-pick finding is repeated by setting times, success rate of pick finding is high resulting in improvement of availability of winder.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a yarn end processing device, and more particularly to a processing system in a spinning bobbin feed device.

[Conventional technology]

A spinning bobbin wound on a spinning machine, especially a ring spinning machine (
The bobbin (hereinafter simply referred to as bobbin) is supplied to the next process, the wine goo, and is rewound into -2 packages. A punch winding is applied to the upper or lower end of the take-up pipe, and before feeding the yarn to the wine goo, the punch winding is unwound and a convenient end of the yarn is opened to start winding.

That is, a device generally called a pick-up device is installed near the wine machine, and the bobbins transferred from the spinning machine are supplied to the wine goo through the pick-out device.

“[The problem to be solved by the invention] When the bobbin that has been successfully tapped by the spinning device is fed to the wine gourd, the yarn end that has been pulled out and the yarn end on the winding package side are automatically spliced and the bobbin is wound. However, even if a bobbin with a failed lead-out is fed to the winder, it is impossible to splice the yarn and is immediately ejected from the winding position without being rewound. The bobbins that had been successfully meddled with were also supplied to Winegoo, causing a decline in Wineter's work efficiency.

The present invention aims to solve the above problem.

[Means for Solving the Problem] The remaining part of the annular transfer path is used as a feedback passage for bobbins that have failed to be picked, and the bobbins that have failed to be picked at the processing station are immediately handled without being ejected from the picking device. It is designed to be transferred to a processing station via a feedback path.

Example] Embodiments of the device of the present invention will be described with reference to the drawings.

In Fig. 1, an annular transfer path (υ) is arranged in the middle of the bobbin (1) conveyance paths (2) and (7), and the receiving station (A) position of the annular transfer path (υ) is at the loading path (2). The bobbin unloading station (D position) of the annular transfer path (L) is connected to the unloading station (7). The passage (L2) is used as the feedback passage for the uncoupled bobbin. That is, the passage (Ll) is the passage from the station prisoner to the station (F'') in the direction of arrow (6), and the passage (L2) ) is a path from station (F) to station (N) in the same direction.

The spun bobbin (1) is transferred in the direction of the arrow (3) along the conveyance path (2) in the tray (normally inserted) and reaches the receiving position fm (A) of the pick-out device. Rotating plate (

A roller αυ is arranged to pull out the thread connected between the cutter 00 and the cutter 00, and lightly wrap it around the surface of the thread layer. Station (Bl
At station (Q), the bobbin (1b) is rotated by a friction roller in the direction (6) for unwinding the wound yarn, and at station (Q) is rotated by roller αυ in the winding direction a.Furthermore, at station (D), Yarn end suction and loosening device α that sucks and loosens free yarn ends
A slit is arranged, for example, composed of a saccidine mouse α with a slit α. In this position, the bobbin (

At O, a thread end insertion mechanism Ql is provided which cuts the thread pulled out from the bobbin into a certain length and inserts the thread end into the center hole (to) of the bobbin (1e).

As shown in Figure 3, the bobbin tray D in this embodiment has a base Cυ and a bobbin insertion peg (2) integrally formed on a disc-shaped base (7), and the inside is open at the bottom. A hollow part q is formed, and the peg (2) has an air passage hole.
By applying a suction air flow in the direction of arrow (A) inside the tray ('I'), suction force (hob ) is what works.

FIG. 2 shows a plan view of the bobbin processing station. Tray (TA) with ivy bobbin inserted in the receiving position (A)
is the processing station (% ~
When reaching F), the bobbin that has been successfully taken out is transferred to the conveyance path (7).
The bobbin that has been ejected or has failed to be ejected is blocked by the movable guide (27a), and then passes through the passage (L2) to reach the ejecting processing receiving position (4) again to repeat the same operation as described above. It has become. That is, the processing station is equipped with a sensor for detecting the end of the pick-up yarn, and when the sensor detects that there is no yarn, a rotary solenoid, etc. This prevents the tray (Tf) from being dispensed when it has reached position (II).

In addition, in Fig. 2, processing stations (B) (C

The tray transfer path is configured by the following.

The tray receiving grooves (5a) to (5h) are formed by approximately the inner half of a circle having a diameter approximately equal to the diameter of the tray, and in the case of this embodiment, the tray receiving grooves (5a) to (5h) are
It is formed at a pitch of 8a.

Further, at two positions around each of the receiving grooves, a pair of rollers (8) and (81) are mounted on the shaft M (
It is located at 11. The contact surface of the roller (8ρ (82)) with the tray protrudes from the circumferential surface (81) of the receiving groove by 5 degrees, and the outer circumferential surface of the tray and the inner circumferential surface of the receiving groove do not come into full contact.

The kite plate 01 has a gap above the rotary plate (4) and has arcuate grooves (84a) to (84h) formed at the same position as the receiving groove. As shown in Figure 12, the base of the tray ('l'1 ■υ
Arc-shaped grooves (84a) to (84h) are located in the portions to prevent the tray from falling or flying upward during transportation.

In addition, in FIG. 4, a plate 01 having a smooth sliding surface with a thickness substantially equal to the thickness of the tray conveyor (8''I) is fixed on the bottom plate on the tray transfer path, and the plate 01 is fixed to the tray transfer path. conveyor ← η station from above (

Next, we will explain the ejecting action of the ejecting device having each of the above-mentioned mechanisms. In Fig. 11, the arrow (

) into the receiving groove (5a). When the phototube sensor (PS) detects the passage of the tray, the rotating plate (4) rotates by one pitch in the direction of the arrow (6) with a fixed time delay via a timer. That is, phototube processor (PS)
Since the rotary plate does not rotate unless it detects the passage of a tray, each station of the rotary plate (4)
There is always a tray received in the receiving grooves (5a) to (5o) of A) to (E), and each station console (4) is empty.
) ~ (It does not appear in the smell. In addition, depending on the case, the receiving groove (5g) (5h) after the dispensing station (F'') may be empty or have a tray present. That is, in the apparatus of the above embodiment, as will be described later, the hohino that misses the thread end is not delivered onto the delivery station (conhair f3η) but immediately passes through the stations (G) and (H) and returns to the receiving station (5). It is controlled by the control device so that it is returned to the bobbin on the conhair and subjected to the picking process again in priority to the bobbin on the conhair.

The bobbin (1b) that has reached the processing station (B) is cut by the cutter device 00 by unwinding the punch wound around the lower end of the bobbin.

Next, move the bobbin of the station run (B) to the station (
It is transferred to the O position, and in this position, the friction roller 0
υ comes into contact with the tray (Tc) and the bobbin (
1c) is rotated in the thread winding direction, and the unraveled thread connected between the bobbin (1c) and the cutter 00 of the previous station (2) is wound on the thread layer surface of the bobbin (1c). Note that winding the thread end in this case does not mean grasping the thread end and actively winding it around the bobbin, but simply winding the thread with the free end lightly passively by rotating the bobbin. By simply winding the yarn, it will not be wound so tightly that it will be difficult to pull out the yarn end on the υ stage.

Next, the bobbin (1d) that has reached station ■ is rotated in the direction in which the thread is unraveled by contact with the friction roller α71 ('I'd), and the thread is unraveled. Succidin mouse αQ located close to the surface of the layer
The thread end is loosened and suctioned. The pulled out thread is the first
Move along the slit ←no shown in the diagram to reach the station (I
The thread crosses between J) and the slit.

Next, when the bobbin is transferred from station (G) to station (G), the pulled out thread (Y3) is guided by the cutter device inner hekite plate 04 and passes through the built-in thread detector, as shown in the first figure. Let feeler work.

At this time, a suction airflow is generated in a suction pipe (not shown) located below the station (scent tray (Te)), and the thread end cut at the cutter position is sucked and inserted into the bobbin center hole a barrel. , the thread end drawing process is completed.

Therefore, when the bobbin reaches the station (1'l), the thread end of a certain length is suspended from the bobbin head into the center hole.
Furthermore, the bobbin is placed on a tray and is discharged onto a conveyance path (7) for supply to the wine gourd.

In addition, in this embodiment, the bobbin that fails to be ejected is not ejected even if it reaches the station (force), and reaches the station prisoner again via the bypass station (G) (to). As mentioned above, simply move the movable guide (Fig. 2 @) provided at station (8) to the position (
Simply moving the bobbin to 27a) is inefficient, since if one bobbin continues to fail to eject, the bobbin that cannot be ejected will be linked endlessly to stations (4) to (2).

Therefore, in this embodiment, when the number of failures in unloading a particular bobbin reaches the set number, the movable guide is not operated and the transfer path is moved from the station (F) to the
7) It is designed to be paid out upwards. That is, a bypass circuit is provided that can track the bobbin that has failed to be picked out.

In Figure 7, the bobbin receiving groove divided into 8 equal parts is connected to the boat 0.
(PorLO-) ~ Named port 7. A station having a thread detection feeler (60a) on a metal plate (the bobbin receiving groove in the second position is designated as boat 0, and the rotation in the opposite direction to the rotation of the rotary plate is designated as boats 1 to port 7. Also, in FIG. 9, the shift register O to 7 in (N) correspond to boats 0 to port 7. Note that bypassing is allowed up to two times, and when discharging a bobbin that has failed three times to the conveyance path (7), each shift register O Set the counter (CO) ~ (C7) corresponding to ~7 to "3".
If the input misses in the state shown in the figure, the shift register starts from 0, so the content of the counter (CO) becomes "1" under the AND condition of the register O and the output miss signal. At the same time, the solenoid (S''+, ) for the movable guide is driven by the feed error signal to bypass the bobbin.

Next, as shown in Figure 8, when the rotary plate (4) advances one pitch,
The shift register advances to register 1 according to the rotation signal (S) of the rotary plate, and if there is a mistake in starting, the counter (C
The content of 1) becomes 111. Therefore, in this case as well, the solenoid (B) is driven to bypass the lead-out mis-bobbin, as described above.

When the rotary plate (4) rotates once and port 0 comes to the input error detection section again, the shift register returns to register O, and if there is an input error here, the content of the counter (CO) becomes "1".
It is added to become "2". In this case as well, the solenoid (5) is driven and the bobbin that failed to be picked out the second time is again bypassed.

In this way, the contents of the counter (CO) are changed to the set value "3".
'', the output of the counter (CO) is set as a solenoid drive prohibition signal, the bobbin is delivered to the transport path (7), and the counter (CO) is reset.

However, if the bid is successful on the second or third time, the counter that matches the boat is reset by the AND condition of the shift register and the bid success signal (Sl), and the solenoid can be driven at any time. Since there is no such bobbin, the successful bobbin is delivered onto the conveyance path (7).

In this way, if a predetermined number of times of mistaking occurs, the bobbin can be chained along the rotary plate and subjected to the picking operation.

In addition, if you simply repeat the regular threading process on a bobbin that has been misaligned once, there is a high possibility that the misalignment will occur again. For this reason, for example, when bypassing, at station (C1 or station 2), a saw blade-like searcher that touches the surface of the yarn layer of the bobbin to search for the yarn end, or an elastic plate-like body that strikes the surface of the yarn layer. It is effective to install a correction device that makes it easier for the yarn end to separate from the yarn layer.In this case, a bobbin that has been successfully pulled out the first time will not be affected by the correction device, so it will not work normally. It does not damage the thread layer surface of the bobbin.

〔Effect of the invention〕

As described above, in the present invention, a bobbin that fails to be picked out is not ejected from the picking device, but is immediately transferred to the picking processing station computer through the feedback passage, and is subjected to the picking operation again. It is possible to increase the operating efficiency of the wine machine.
