Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bobbin transfer device for a spinning winder in which a canopy spinning machine and an automatic winder are linked.

[Prior Art] Conventionally, as shown in FIG. 5, a bobbin transfer device for a spinning winder connects the bobbin conveying path 4 of the spinning machine 1 and the winder 2 at the interface section 3 between the spinning machine 1 and the automatic winder 2. It is directly connected to the bobbin conveyance path 5, forming one closed loop conveyance path as a whole. The bobbin transport path 5 of the winder 2 consists of a real bobbin transport 11@5a that receives the real bobbins 7 from the spinning fit, and an empty bobbin transport H5b that returns the empty bobbins 6 to the spinning machine 1.

The real bobbin 7 that has been groove-wound on the Tuna spinning machine 1 has all the spindles S1 to Sn.
They are all doffed all at once and supplied to and inserted into the bobbin tray 8 provided on the bobbin conveyance path 4 of the spinning machine 1. and,
The bobbin is sequentially conveyed from the interface section 3 to the actual bobbin conveyance path 5a, conveyed and supplied to each of the winding units W1 to Wn in the next process via the winding device 9, and is rewound.
The empty bobbin 6 now empty is transported on the empty bobbin transport path 5b and returned to the spinning frame 1.

At this time, in the interface section 3, a first sensor 10 detects the presence or absence of the empty bobbin 6 on the empty bobbin transport path 5b.
and a second sensor 11 for detecting the presence or absence of the real bobbin 7 on the real bobbin transport path 5, and operates as follows. That is,
The empty bobbin 6 cut out from the winder is the first sensor 1
When it reaches the 0 position, the first sensor 10 outputs an "empty bobbin arrival signal" and a "real bobbin request signal", thereby driving the transfer device of the spinning machine 1 by one pitch. That is, the spinning machine 1 executes extrusion of the real bobbin 7,
This is supplied onto the actual bobbin conveyance path 5. winder 2
rfI! J uses the second sensor 1l to confirm receipt of the real bobbin 7, and if the pushed out real bobbin 7 does not arrive within a certain period of time, it outputs a "real bobbin feeding abnormal signal". [Problems to be Solved by the Invention] However, in the conventional spinning wine goo bobbin transfer device, the real bobbin transfer path 5a and the empty bobbin transfer #I5
b constitutes one closed loop system as a whole. For this reason, among the bobbin conveyance paths 4 on the spinning spinning tR1 side, the spinning spinning R
Outward path 4a and return path 4b corresponding to each weight S1 to Sn of 1
Not only the upper real bobbin 7 but also each spindle S1 of the remaining spinning frame 1
Even the empty bobbins 6 on the conveyance path relay section 12 that do not correspond to ~Sn are all temporarily sent to the winder 2 side. When looking at this from the winder 2 measurement, the unnecessary empty bobbin 6 that has no relation to rewinding will pass through the conveyance path 5 once when the winder is open, which is not only wasteful in itself, but also
This results in a delay in the supply of real bobbins, and also causes various troubles because the empty bobbins 6 and the real bobbins 7 are mixed together.

Especially when rewinding thick thread using an automatic winder,
Since the processing time per bobbin is short, the bobbin supply operation tends to be delayed, and depending on the case, waiting time occurs in the winding units W1 to Wn.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a bobbin transfer device for a spinning winder that does not supply empty bobbins from the spinning machine to the winder. [Means for Solving the Problems] In order to achieve the above object, the spinning wine goo bobbin transfer device of the present invention makes the bobbin conveyance path of the spinning *IllJ a closed loop with a return path, and the delivery position of the return path is is the actual bobbin supply path that carries the tray and passes it to the winder.
An empty bobbin return path from the winder side is connected to the downstream receiving position, and a tray in the bobbin transport path that does not correspond to each spindle on the spinning machine side is fixed to the transport path, and empty bobbins that have arrived at the empty bobbin return path are fixed to the transport path. This configuration is provided with a means for confirming that the conveyor remains stationary for a predetermined period of time and then moving the conveyor path by one pitch.

[Function] When the bobbin conveyance path of the spinning machine is fed one pitch, all the bobbin trays in the bobbin conveyance path of the spinning machine are sequentially moved.
It comes to the delivery position of the return path of the spinning I measurement. Bobbin tray (actual bobbin) in the part that does not correspond to the stacking machine spindle
When the tray reaches the delivery position, the tray is transferred to the real bobbin supply path and is supplied to the wine goo side. However, when the bobbin tray (empty bobbin) that does not correspond to the spinning machine spindle comes to the delivery position, this bobbin tray is fixed to the bobbin m feeding path, so it cannot be transferred to the actual bobbin feeding path, and it remains as it is. Proceed downstream along the return path on the spinning machine side.

That is, the empty bobbin will not flow into the winder measurement.

When the fixed bobbin tray is present at the receiving position of the return path of the spinning machine, the empty bobbin that has arrived at the empty bobbin return path from the winder track stops because there is no empty bobbin in the return path of the spinning fill FJ. When this stopping is confirmed for a predetermined period of time, the bobbin transport path of the spinning machine is fed by one pitch. In this way, one-pitch feeding is repeated as long as the empty bobbin remains stationary, and all fixed bobbin trays are used for spinning.
It passes through the return path of the measurement. Then, from when the empty space of the real bobbin transferred to the real bobbin supply path reaches the receiving position of the return path on the spinning machine side, the empty bobbin that has been stopped and waiting in the empty bobbin return path starts spinning. It is accepted into the return path of fHFJ and returned to the spinning i measurement. The following empty bobbins are spun one after another after confirming that they have stopped for a predetermined time and feeding one pitch! It will be returned to you for measurement. In this way, spinning R
The PJ bobbin conveyance path can also be circulated for one cycle in the same way as in the winder measurement, and only trays of actual bobbins are supplied to the winder measurement, and empty bobbin trays are not supplied to the winder measurement. Therefore, the bobbin feeding capacity of the spinning winder as a whole is increased, and the bobbin feeding operation of the spinning winder as a whole is not delayed.

[Example] A preferred embodiment of the present invention will be described based on the accompanying drawings. In the spinning winder (not shown in FIG. 1), the bobbin conveyance path 4 of the spinning machine 1 and the bobbin conveyance path 5 of the automatic winder 2 are independent of each other, and closed loops I and II transport the trays 8 in the directions of the arrows, respectively. It is a transport route for That is, spinning machine 1
The bobbin transport path 4 is provided with a return ElB 1 3 in front of the interface section 3, which short-circuits the outgoing path 4a and the incoming path 4b. Further, the return path 13.1 in the interface section 3 is also short-circuited between the real bobbin conveyance path 5 and the empty bobbin conveyance path 5b of the automatic winder 2 by the return N14 before the interface section 3.
4 are connected by a real bobbin supply path 15 and an empty bobbin return path l6. In this case, the real bobbin supply path 15 is located upstream of the empty bobbin return path 16 when viewed from the tray transfer direction in the return path 13 of the spinning frame 1. Real bobbin supply path 15 and empty bobbin return li! The ends of 816 are at the same height level as the return path 13 of the spinning frame 1, and share half the width of the passage of the bobbin tray 8. This means that the real bobbin 7 of the spinning machine 1 is extruded from the outgoing path 4a of the bobbin transport path 4 and transferred to the real bobbin supply path 15, and the empty bobbin 6 from the transport path relay section 12 of the spinning machine 1 is returned as is. Pass route 13 and return to 1i
This is to make it possible to return to 1g4b.

A large number of bobbin trays 8 are arranged in a line on the closed-loop transport path 4 of the spinning machine 1 with front and back contact. The spinning machine 1 consists of a spinning machine group CI and an S i+ consisting of spindles S1 to S1.
It is divided into spinning machine group C2 consisting of 1 to Sn weights,
They only belong to the outbound route 4a and the return route 4b, respectively. Therefore, the transport path relay section 12 and the return #I13 do not have spinning machine spindles to which they belong, and even if the spinning tube yarns are doffed all at once, there is no real bobbin (tube yarn) in this area.
7 will not be produced, that is, it will remain as an empty bobbin 6. In order to prevent this empty bobbin 6 from running into the winder 2, the trays 8 in the conveyance path relay section 12 and the return path 13 are attached to the conveyor belt in advance by means of a fixed stage 17 (Fig. 2) such as a hook. Fixed. In order to fix the tray to the belt using the fixing means 17 in this way, the belt needs to be made into a closed loop with one round belt or with an endless flat belt arranged vertically. For convenience of explanation, FIG.
It is divided into a spinning machine group C2 with zero spindle, and eight trays b1 to b4, b5 are provided in the conveyance path relay section 12 and the return path 13, respectively.
This shows the case where ~b8 are consecutive. Real bobbin (pipe thread) 7
Trays bl to b4 are not produced. b5 to b8 are fixed in advance to the conveyor belt by the fixing means 17, and are always circulated together with the bobbin conveyance path 4. In the empty bobbin return path 16 of the interface section 3, a sensor 18 for detecting the arrival of the empty bobbin 6 is provided at a position two bobbin trays before the return path 13, that is, at a position two bobbin trays from the return path 13. One of the 9 sensors 18 is composed of a proximity switch that detects a tray, for example, and when it continuously detects the tray 8 of the empty bobbin 6 for a certain period of time, for example, 1 second, it considers the arrival of the empty bobbin 6 and issues an "empty bobbin arrival signal". ” is output. In response to this signal, the transfer device of the bobbin conveyance path 4 of the spinning machine 1 performs one-pitch drive. The above-mentioned time of 1 second is also the time required to feed one pitch. However, when the detection time of the sensor 18 is short, for example, 0.5 seconds, this is ignored as a mere passing of the empty bobbin 6.

Next, the operation of this embodiment will be explained with reference to FIGS. 2 to 4.

Here, it is assumed that real bobbins A1 to A100 are doffed in one doffing process by spinning machines CI and C2, and empty bobbins B1 to B100 are cut out by each winding unit W1 to Wn. The real bobbin 7 that has been fully wound on spinning machine 1 is transferred to spinning machine group C1.
The real bobbins A1 to A50 are real bobbins A1 to A50 in spinning machine group C2.
51 to A100 are doffed all at once, and supplied to and inserted into the bobbin tray on the bobbin conveyance path 4 of the grain huller 1. This one
In the state of doffing for the second time, as shown in Figure 2,
The fixed tray b4 is at the intersection position with the real bobbin supply path 15 (delivery position Pi), and the fixed tray b1 is at the intersection position with the empty bobbin return path l6.
The intersection position (located at the receiving position P2).

On the other hand, on the automatic winder 2 side, the real bobbin is rewound by each winding unit W1 to Wn while being inserted upright in the bobbin tray, and the empty bobbin 6 (81 to B1
00) are discharged from each winding unit W1 to Wn, transferred to the interface section 3, and formed in a row on the empty bobbin return path 16. (1) Continuous feeding of fixed trays and supply of real bobbins In FIG. Stop for a while. The sensor 18 is arranged to detect the empty bobbin 6 at the detection position Ps. Since the empty bobbin B1 remains stationary for a predetermined time (1 second), the sensor 18 outputs an "empty bobbin arrival signal".

As a result, the transfer device of the spinning frame 1 is driven by one pitch, and the real bobbin A1 comes to the delivery position Pl, and the fixed tray b2 comes to the empty bobbin receiving position ffP2.

Since the real bobbin A1 is half placed on the belt conveyor of the real bobbin supply path 15 at the delivery position P1, it is automatically carried in the direction of the arrow by the belt conveyor of the real/bobbin supply F#115 and reaches the delivery position! Pi becomes a blank space (X1). On the other hand, empty bobbin B1
cannot move into the bobbin transport path 4 because the fixed tray b2 exists at the receiving position P2 and is obstructed.

That is, the empty bobbin Bl still remains in the state shown in FIG. 2.

Since the empty bobbin B1 remains stationary for a predetermined period of time (1 second), the sensor 18 outputs an "empty bobbin arrival signal". As a result, the transfer device of the spinning machine 1 is driven by 1 bit,
The real bobbin A2 comes to the delivery position Pi, and the fixed tray b3 comes to the empty bobbin receiving position P2. Actual bobbin A at delivery position P1
2 is placed on the real bobbin supply path 15 and supplied to the winder 2. Similarly, the sensor 18 confirms that the empty bobbin B1 remains for 1 second, and the bobbin transport path 4 is fed by 1 pitch, so that the real bobbin A3 comes to the delivery position P1 and the fixed tray b4 comes to the receiving position P2. The real bobbin A3 is supplied to the winder 2. (2) Start of accepting empty bobbin (Fig. 3) Since the empty bobbin B1 is still in the state shown in Fig. 2, the sensor 18 again confirms that the empty bobbin B1 is stationary (for 1 second), and the bobbin transport path 4
1 pitch feed is performed. As a result, the real bobbin A4
is in the delivery position P1, empty space x 1 after sending out the actual bobbin (A1)
comes to the receiving position P2 (Fig. 3). The real bobbin A4 at the delivery position P1 is placed on the real bobbin supply path 15 and supplied to the winder 2, and the place where the real bobbin A4 was present becomes a vacant space X2.

On the other hand, as described above, since the receiving position P2 is the empty space X1, the empty bobbin B1 that has been parked up to that point is received in the empty space X1. The second empty bobbin B2 following this is placed in the empty space X1.
It is obstructed by the empty bobbin B1 that has entered, and stops at the detection position Ps. Therefore, after 1 second has elapsed, the bobbin transport F
I? I4 is advanced by one pitch.

Thereafter, in the same manner, 50 tons of real bobbins A5 to A are fed to winder 2, and empty bobbins 82 to B47 are fed to spinning 1.
Returned to 11fll.

(3) Arrival of fixed trays Subsequently, fixed trays b5 to b8 that were present in area 9'A of conveyance path relay section l2 arrive at delivery position P1.

Since these trays 8 are fixed to the bobbin conveyance path 4 by the fixing means l7, they are connected to the actual bobbin supply path 15 at the delivery position P1.
Even if the bobbin is halfway on the belt conveyor, it cannot go out of the bobbin conveyance path 4. In other words, the supply of real bobbins is no longer available.

However, there are already real bobbins A48 to A in the return path 13.
Since there are 50 empty spaces X48 to X50, empty bobbins 848 to B50 are sequentially received in these empty spaces X48 to X50 and returned to the spinning machine 1.

(4) Continuous feeding of fixed trays and supply of actual bobbins When the fixed trays b5 to b8 of the relay section 12 arrive at the receiving position P2 (Fig. 4), the same steps as already explained in Fig. 2 are carried out.
Since the empty bobbins B51 and subsequent ones come into contact with these fixed trays b5 to b8 one after another, the empty bobbins B51 become stationary again. In other words, while the retention time (1 second) is confirmed by the sensor 18, the bobbin transport R4 is carried out sequentially.
The I bit feed is performed. At this time, from the delivery position P1, the real bobbins A51 to A53 are supplied to the winder 2 through the real bobbin supply path 15. (5) End of 1st cycle In the same manner as described in (2) above when starting to accept empty bobbins, actual bobbins A54 to A100 are transferred to winder 2 fl.
The empty bobbins 851 to B97 are returned to the spinning frame 11 rules. When the fixed tray arrives, the empty bobbins 398 to 398 are placed in the empty spaces X98 to
The BIOOs are accepted one after another and returned to the R1 side.

The spinning machine 11 integrates the above-mentioned total of 108 pitches of feed and detects that the predetermined value has been reached and determines that one cycle is complete, or the tray marked in advance returns to its initial position. When this is detected, it is determined that one round is completed, and a permission signal is generated to enable the next doffing.

According to the above embodiment, the empty bobbins in the conveyance path relay section 12 and the return path 13 are not unnecessarily sent to the winder measurement, and the bobbin supply capacity of the entire spindle winder l is at least as low as conventionally. The number increases by the number of empty bobbins 6 in the conveyance path relay section 12. Therefore, even if the automatic winder handles a large yarn count and the rewinding time per bobbin is short, there will be no delay in the bobbin feeding operation of the entire spinning winder. [Effects of the Invention] In summary, According to the present invention, the bobbin transport path of the spinning a-open can also be circulated for one cycle in the same way as the winder, and only trays of real bobbins are supplied to the winder, and trays of empty bobbins are not supplied to the winder. The bobbin Q (feeding capacity) of the entire spinning winder is increased, and the bobbin feeding operation of the entire spinning winder is no longer delayed.
