〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of the device of the present invention.

Following the end of the bobbin discharging conveyor (2) arranged along the winding unit of the automatic winder (1), the bobbin processing device (3) according to the present invention is installed. The bobbin processing device (3) includes a bobbin aligning device (4) that separates the various bobbins that are randomly transferred and arranges them in one line, and a discharging device for a bobbin with a residual thread such as a full bobbin or a half ball bobbin ( And 5) are provided on the in-conveyor (6). The empty bobbin and the bobbin with the minimal residual thread sent from the upper end of the incline conveyor (6) are supplied to the bobbin top end control device (8) via the chute (7). Subsequently, a bobbin discharge device (10) with a minimum amount of yarn is provided in the middle of the bobbin transport conveyor (9) whose azimuths are aligned. (11) is a lattice conveyor for carrying out the empty bobbins aligned in a certain direction to the next process, in which the bobbin receiving plate is fixed to the belt (12) which rotates in the vertical direction.

By the way, the bobbin delivered from the winder (1) onto the conveyor (6a) is delivered in various states as described above, and the amount of yarn layer, the direction of the bobbin, and the transfer of two or three bobbins in parallel. Etc. are extremely random. That is, the second
As shown in the figure, bobbins (B) may be overlapped and transferred at the conveyor end of the winder. The ink line conveyor (6) is provided with an aligning device (4) for aligning the bobbins in a line.

In FIGS. 1 and 3 and 4, one conveyor belt (6) forms the respective conveying paths of the horizontal portion (6a) and the inclined portion (6b), and on the belt (6) at a predetermined pitch, A locking piece (13) for locking is fixed to one end of the bobbin, and the bobbin is transported on the inclined portion (6b) by the locking piece (13).
Also, as shown in FIG. 4, the length of a certain range (for the angle (θ) in FIG. 1) moving from the horizontal part (6a) to the inclined part (6b) is as shown in FIG.
4) Guide surface (15) that guides the belt (6) inside (14)
A) and a pair of guide blocks (15) and (15) having inclined surfaces (15b) for guiding the bobbin (B) are fixed to the side plates. A gap is provided between the blocks (15) and (15) so that the locking piece) can pass therethrough.

The angle (θ) is an angle corresponding to a transfer path of at least the length of the bobbin. Further, the rising amount () of the locking piece (13) from the belt surface (6) is the empty bobbin (B1).
It is sufficient that the average value diameter (d1) is approximately equal to. The maximum diameter is preferably 1.5 times or less. That is, in the state shown in FIG. 4, the rising amount that allows two empty bobbins to be transferred simultaneously is not possible. Further above guide blocks (15)
The width (W) between the side plates (14) and (14) of the part (15) is set so that one full bobbin passes through and two empty bobbins cannot be transferred side by side. (16) is a guide roller for the belt (6).

Therefore, even if two bobbins (B1) and (B2) are transferred one on top of the other as shown in Fig. 3, only the lower bobbin (B1) is transferred by being pushed by the locking piece (13). However, the upper bobbin (B2) is not locked to the locking piece, and due to the inclination of the conveyor, the bobbin (B2) becomes a bobbin (B1).
It slides down on top and is locked by the next locking piece or, in some cases, by a further locking piece.

After all, the bobbins are separated one by one, and the slanted part (6
b) will be transferred upward.

Next, the bobbin discharging device with residual thread (Fig. 1 (5)) for checking the thread layer of each separated bobbin is shown in Figs.
This will be described with reference to the figure.

The bobbin discharging device (5) with residual thread is a bobbin sensor (17) with residual thread that engages with a yarn layer of the bobbin with residual thread on the inclined conveyor (6) and is displaced by a detection signal of the sensor. It is composed of a payout mechanism (18).

The residual thread detection sensor (17) has a support block (21) pivotally supported by a shaft (20) supported by a fixed bracket (19), and engages a thread layer on the block to rotate around the shaft (22). A displaceable feeler (23) and a microswitch (25) that comes into contact with and separates from the actuator (24) are installed in a part of the feeler (23). The feeler (23) is biased around the shaft (22) by a spring (26) counterclockwise in FIG. 5, and a brush-like engaging member (27) for engaging a thread is provided on the lower surface of the tip. It is a thing.

The bolt (28) in FIG. 6 is used for positioning the block (21) and is used for adjusting the distance from the frame (29) of the block (21). When using, screw the bolt (28) and brush (27)
It is convenient to adjust the lower end of the belt so that it is slightly closer to the belt (6) side.

In FIG. 5, (18) is an example of a means for discharging the bobbin (B2) with residual thread from above the conveyor (6), and the air nozzle (3
0) is arranged toward the bobbin on the conveyor.

Reference numeral (31) is a solenoid valve which operates by a detection signal of the sensor (17). A notch (32c) of sufficient length to discharge the bobbin with residual thread is formed in one guide plate (32b) of the guide plates (32a) (32b) on both sides of the conveyor, and the air jet (33)
The bobbin (B2) is easily discharged and dropped to the side of the conveyor. (34) of FIG. 1 is a container for the falling bobbin.

Next, the bobbin crest control device (8) will be described with reference to FIGS. The direction control device (8) is mechanically controlled by utilizing the difference in diameter between the small diameter side end portion (hereinafter referred to as the top portion) and the large diameter side end portion (hereinafter referred to as the tail portion) of the bobbin (B). To do. That is, the chute (7) that receives the bobbin falling from the upper end of the ink line conveyor (6)
Following this, the bobbin passes through the top end control passageway (35) and drops downward in the present embodiment. Following the chute (7), the slightly inclined receiving surface (36) is attached to the side wall (3
The cut-out piece (39) fixed to the receiving surface (36) and operated by the optical sensor (38) that detects that the bobbin (B1) is placed on the receiving surface (36) oscillates around the single axis (40). Be movably supported. An output shaft (42) of an actuator (41) such as a rotary solenoid or a motor is fixed to one end of the shaft (4c). By opening the cutout piece (39), the bobbin moves to the guide member (4
3) (44) Roll up. The guide members (43) and (44) have a width (S) smaller than the diameter (d1) of the top of the bobbin and a width (S) larger than the diameter (d2) of the bottom as shown in the eighth and ninth drawings. The passing gap (45) is formed.

Therefore, when the bobbin (B1) is to be placed as shown in FIG. 9, the bottom (B1b) is prevented from falling by the guide member (44), and the top (B1a) passes through the gap (35). So, the top (B1
It drops in the chute (46) as shown in Fig. 8 with a) facing down.

Similarly, when the bobbin's top is the opposite of that shown in FIG. 9, the bobbin is dropped with the top down. Therefore, the bobbin (B1) placed on the lower conveyor (9) from the chute (46) is transferred on the conveyor (9) with the top as the front when the conveyor (6) advances in the direction of the arrow (47). It is.

Then, a discharging device (10) for the bobbin with a minimum amount of yarn is provided on the way of the conveyor (9) in FIG.

This device is the same as the bobbin discharging device (5) with residual thread shown in the fifth and sixth figures, and the position of the feeler (23) is moved slightly to the conveyor side to detect the minimum residual thread. is there. That is, the bolt (28) shown in FIG. 6 is attached to the bracket (21).
The bracket (21) supporting the feeler (23) slightly rotates in the counterclockwise direction around the shaft (20) by screwing it in to the side, and the lower end of the brush (27) becomes a minimal residual thread. The position is adjusted so that it can be engaged. The point that the air is ejected from the conveyor (9) by the jet air is the same as the above, and the accommodating box (48) for the bobbin with the minimal residual thread is installed on the side of the conveyor (9) in FIG.

After passing through the above devices, only the empty bobbin is placed on the conveyor (9b) in FIG. 1, and subsequently, the empty bobbin is conveyed to the spinning machine side where the empty bobbin is required.

As a conveying means to the spinning machine, for example, a device as shown in FIGS. 1 and 10 can be connected.

That is, a vertical lattice conveyor (11) is installed after the horizontal conveyor (9), empty bobbins are conveyed upward one by one, and inserted into the tray (50) on the ceiling tray conveyor (49). After that, the empty bobbin integrated with the tray is conveyed to the spinning machine.

The vertical lattice conveyor (11) above has upper and lower pulleys (52) (5
2) The bobbin receiver (54) is fixed to the belt (53) hung between them at a constant pitch, and the empty bobbin (B1) delivered from the upper end to the chute (55) by appropriate means is It is mounted on the tray (50) that stands by.

That is, in this system, the fine spinning bobbins that have been doffed by the fine spinning machine are separately inserted into the tray (50),
After being transported to the winder side, the spinning bobbin taken out from the tray is supplied to a bobbin storage magazine provided in each winding unit of the winder. When the empty trays from which the spinning bobbins have been removed are transferred to the empty bobbin supply position (56), empty bobbins are inserted and supplied one by one from the lattice conveyor (11).

Therefore, the number of empty bobbins discharged from the winder shown in FIG. 1 does not always match the amount of empty trays generated, and for example, even when the empty tray reaches the empty bobbin supply position, the empty bobbin is not always on the lattice conveyor. Not necessarily, and conversely, even if an empty bobbin is on the lattice, it does not mean that an empty tray has arrived. Therefore, the lattice conveyor is provided with an empty pobin reserve device (57).

The reserve device (50) has a zigzag bobbin storage path (58) formed from the upper end to the middle of the lattice conveyor (11), and the inlet (59) is provided at the upper end of the storage path (58). A movable guide (60) for opening and closing is installed, and an empty bobbin cutting device (61) shown in FIG. 12 is provided at the lower outlet.

When the movable guide (60) is in the closed position shown by the solid line in Fig. 10, the empty bobbin falling from the lattice conveyor is the chute (55).
It is dropped onto the tray (50) through the tray (50) while the empty bobbin is in the zigzag reservoir (5
8) Drop in. Further, in FIG. 12, the bobbin cutting device (61) is a cutting piece which swings about one axis (62).
(63) (64), bobbin (B1) at the bottom of the storage channel (58)
Are cut out one by one, rolled on the guide plate (65), and supplied to the bobbin receiver (54) on the lattice conveyor (11). The cut-out pieces (63) (64) connected by the lever (68) to the member (67) that moves forward and backward by the drive of the electromagnetic solenoid (66) or fluid cylinder etc. are located at the two-dot chain line positions (63a) (64a) and the solid line position. (63) By moving between the areas further to the right of (64), empty bobbins are cut out one by one.

In addition, FIG. 11 shows the structure of the connecting portion between the horizontal conveyor (9) and the lattice conveyor (11). A notch (70) is formed in the side wall (69) of the horizontal conveyor (9) and a stopper (71) is formed.
The empty bobbin (B1) rolls on the bobbin receiver (54) on the lattice conveyor by the guide member (72) slightly inclined toward the lattice conveyor.

If the horizontal conveyor (9) also has a portion corresponding to the notch (70) and is inclined toward the lattice conveyor, the bobbins can be delivered and received more smoothly.

In such an empty bobbin processing device, since the bobbin discharged from the winder excludes the bobbin with residual thread, the bobbin with minimal residual thread, etc., the number of empty bobbins reaching the lattice conveyor (11) gradually decreases. . For this reason, the operator needs to supply the empty bobbin to the storage passage (58) as appropriate, but in this embodiment, the empty bobbin is only supplied onto the horizontal conveyor (9) in FIG. It is possible to transfer and store it to the storage channel (58) via (). In order to reduce the bobbin in the storage passage, a bobbin detection sensor such as a photoelectric type or mechanical feeler is provided at an arbitrary position of the zigzag storage passage, and when the sensor detects the absence of the bobbin, a warning means such as a lamp is activated. By doing so, it is possible to prompt the operator to supply the empty bobbin.

In the above apparatus, the bobbins of various random states discharged from the winder are aligned by the ink line conveyor (6). Subsequently, the bobbin with residual thread is discharged to the outside of the conveyor system detected along the inclined conveyor (6a), and the top of the bobbin is aligned through the direction and attitude control device (8). Since the bobbins with threads are detected and delivered along the horizontal conveyor (9), only empty bobbins remain on the conveyor.

Therefore, the selected empty bobbins can be carried to the spinning machine side by a carrying means such as the tray.

〔The invention's effect〕

As described above, in the present invention, it is possible to automatically select various bobbins discharged from the existing winder and convey only the empty bobbin, and between the existing winder and the spinning machine without the operator's hand. The empty bobbin can be transported.

That is, only empty bobbins discharged from the winder can be inserted into the tray one by one, and can be conveyed to the spinning machine side, and by providing a reserve device on the lattice conveyor, the empty bobbins can be smoothly supplied to the tray. It is possible,
The empty bobbin can be efficiently conveyed between the existing winder and the spinning machine without an operator.
