BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube changing device and a roving machine in a roving machine equipped with an upper-supported flyer.

[0002]

2. Description of the Related Art In recent years, there has been a remarkable tendency in roving machines to achieve higher speeds and large packages in order to improve productivity.
Therefore, the doffing operation of removing the full bobbin from the bobbin rail and the operation of inserting the empty bobbin into the bobbin wheel not only require a considerable amount of labor (especially doffing operation) but also increase the time required for the operation. As a result, the operating rate of the roving machine is reduced. For this reason, various proposals have been made regarding automation of the pipe replacement operation including the doffing operation and the subsequent supply of the empty bobbin.

Conventionally, for example, Japanese Patent Application Laid-Open No. 58-81624 has proposed an apparatus shown in FIG. This apparatus is provided above the roving machine 101 so that the rail 10 is perpendicular to the machine base longitudinal direction (perpendicular to the paper).
2 is provided, and a crane 103 is provided movably along the rail 102. The crane 103 has transport rails 104, 10 having substantially the same length as the entire length of the roving machine 101.

A carriage (not shown) in which bobbin hangers 108 are arranged in one row at the bobbin pitch of the roving machine 101 is provided on the transport rails 104 and 105. On the front side of the roving machine 101, a tube changing machine 109 is disposed so as to be movable between a standby position shown in FIG. 19 and a working position proximate to the roving machine 101 advanced from the position.

At the time of a pipe change operation, the crane 103 is moved and arranged at a position where the first transport rail 104 faces the pipe change arm 110 of the pipe changer 109 at the standby position. In this state, the refilling machine 109 moves forward to the working position, suspends the full bobbin F on the bobbin rail 111 on the refilling arm 110, then retreats to the standby position and arranges the refilling arms 110 in a line. I do. Next, the elevating device 106 operates to lower the first transport rail 104. Then, after the full bobbin F is hung on the bobbin hanger 108, the transport rail 104 rises and returns to the original position. Next, the crane 103 is moved to a position where the second transfer rail 105, on which the empty bobbin E is suspended from the bobbin hanger 108, faces the tip of the replacement arm 110, and the elevating device 107 operates to operate the second transfer rail 10
5 falls. Then, after the empty bobbin E is delivered to the replacement arm 110, the second transport rail 105 rises and returns to the original position. Next, the refilling machine 109 moves to the working position, and places the empty bobbin E on the bobbin rail 111.
It returns to the standby position and the pipe replacement work is completed.

Japanese Patent Application Laid-Open No. 6-41827 proposes an apparatus shown in FIG. This replacement device 112
Is disposed in front of the roving frame 101 over the entire length of the frame. The refilling device 112 includes a refilling head 114 provided with a refilling arm 113 arranged in a staggered manner in opposition to the bobbin of the roving machine 101, and the refilling head 114 has a standby position indicated by a solid line by a pantograph mechanism 115; The bobbin transport body 117 that stands by on the support rail 116 disposed above the roving machine 101 can move up and down between a bobbin transport body 117 and a corresponding elevated position indicated by a chain line.

On the front side of the tube changing device 112, pegs 118 for temporarily placing empty bobbins E are arranged in a staggered manner along the roving machine 101. In addition, the replacement head 114 is used to move the replacement arm 113 forward and backward simultaneously to a position above the bobbin rail 111, and a long arm of the replacement arm 113 arranged in a staggered manner. And a telescopic mechanism for expanding and contracting.

[0007] The tube changing device 112 performs a tube changing operation by a combination of lifting and lowering of the tube changing head 114 by the operation of the pantograph mechanism 115 and longitudinal movement of the tube changing arm 113 by the operation of the tube changing arm back-and-forth moving means and the expansion and contraction mechanism. I do. At the time of a pipe replacement operation, first, the empty bobbin E suspended from the bobbin hanger 119 of the bobbin transport body 117 is removed and placed on the peg 118. Next, the full bobbin F on the bobbin rail 111 is hung on the tube changing arm 113, the full bobbin F is taken out from the roving machine 101, and hung on the bobbin hanger 119 of the bobbin transport body 117. Thereafter, the empty bobbin E mounted on the peg 118 is mounted on the bobbin wheel of the bobbin rail 111.

Then, as shown in FIG. 10A, after the bobbin rail 3 is raised to the winding position, winding of the roving is restarted.

Next, the motor 19 is rotated forward and the support rail 5 is rotated.
Is lowered. After the support rail 5 is lowered by a predetermined amount, the motor 19 is driven to rotate in the reverse direction and the support rail 5 is raised to a predetermined position, and the state shown in FIG. The bobbin hanger 6 was inserted into the full bobbin F while the support rail 5 was lowered by a predetermined amount, and the locking portion (not shown) was locked to the full bobbin F when the support rail 5 was lowered to the predetermined position. State. Then, the support rail 5 slightly rises from that state, so that the full bobbin F is suspended from the bobbin hanger 6.

Next, the servo motor 27 is rotated in the reverse direction to
4 retreats to the standby position, and becomes the state shown in FIG. In this state, each fork 30, 31 is full bobbin F
It is arranged at a position that does not hinder the upward movement of the vehicle. Next, the motor 19 is driven in the reverse direction to raise the support rail 5 to the raised position (standby position), and the state shown in FIG.
A series of replacement work is completed. Until the next full package, the bobbin transporter 7 with the full bobbin F suspended is carried out from the support rail 5 to the spinning process, and the bobbin transporter 7 with the empty bobbin E suspended is supported instead. It is carried into the rail 5.

This embodiment has the following effects. (1) The full bobbin F and the empty bobbin E can be suspended simultaneously on the forks 30, 31 arranged at the same pitch as the bobbin wheel pitch P. Accordingly, the empty bobbin E or the full bobbin F is temporarily suspended by simultaneously suspending the empty bobbin E received from the bobbin carrier 7 and the full bobbin F taken out from the roving machine 2 on the forks 30 and 31 at the time of the pipe replacement operation. It is possible to transfer the full bobbin F to the bobbin transporter 7 common to the empty bobbin E and the full bobbin F, that is, the bobbin transporter 7 after the empty bobbin E is removed, even if there is no place where the empty bobbin E is removed. Become.

(2) Two types of long and short forks 30, 31
Are formed by a common fork body 35 and two types of support plates 33a and 33b having different lengths. Therefore,
When the fork (supporting piece 35a) is damaged, only the fork body 35 need be replaced instead of replacing the entire fork. Further, since the fork main body 35 is formed by casting, the manufacturing cost becomes easier as compared with the case where the bobbin suspension portions 36a and 36b are formed by cutting.

(3) The forks 30, 31 are fixed to the cart 24 constituting the tube replacement device main body 22, and are arranged at predetermined positions by the advance and retreat of the cart 24, so that the forks 30, 31 themselves can be expanded and contracted. The configuration is simpler than when the configuration is made as described above. Further, the bending moment acting on the forks 30, 31 can be reduced, and the movement and delivery of the full bobbin F can be performed smoothly even when the rigidity of the forks 30, 31 is low.

(4) The full bobbin F is
1, the bending moment acting on the forks 30, 31 is smaller than when the full bobbin F is hung on the front bobbin hanger 36 a.

(5) When the empty bobbin E is delivered to the bobbin wheel 4 and the forks 30 and 31 are retracted to a position where they do not hinder the operation of the roving machine 2 during the pipe changing operation by the pipe changing apparatus body 22, The operation of the table is resumed. That is,
Since the machine is restarted before the completion of the transfer operation, the machine stop time is shorter than when restarting the machine after the completion of the transfer operation, and the operating rate of the roving machine is improved. I do.

(6) The fork body 35 is fixed to the support plates 33a, 33b with the step 35b formed at the base end being in contact with the distal ends of the support plates 33a, 33b.
It is easy to fix the fork body 35 straight to the support plates 33a, 33b. Also, fork 30,
Even when 31 is moved to the full bobbin F receiving position, even if it comes into contact with the full bobbin F and receives an impact, most of the force is carried by the support plates 33a and 33b, and the shearing force acting on the bolt 34 is reduced. It becomes smaller and the durability is improved.

(7) Since the support plates 33a and 33b are fixed to the support plate 29 in a state where the steps are in contact with the tips of the support plates, the same effects as in (6) can be obtained.

(8) Since the rubber magnet 41 is provided on the front bobbin suspension portion 36a on the front side where the bobbin suspended on the forks 30, 31 is likely to swing, the empty bobbin E suspended on the bobbin suspension portion 36a swings. Is suppressed, and the moving speed of the bogie 24 is increased to shorten the tube change time.

(9) Since the support rail 5 is fixed to the support bracket 10 which is raised and lowered along the column 11 by the ball screw mechanism, it is compared with a configuration in which the support rail 5 is raised and lowered while being suspended by a chain or the like. Therefore, even if the lifting speed is increased, the swing of the bobbin hanger 6 is reduced. Therefore, it contributes to shortening of the tube replacement time.

(10) Since the refilling operation is started at the same time as the full-package signal, the stop of the machine is stopped compared to the case where the refilling operation is started after the machine stops when the bobbin rail 3 is lowered to the doffing position. Time is shortened.

(Second Embodiment) Next, a second embodiment will be described with reference to FIGS. In this embodiment, the support rail 5 for supporting the bobbin carrier 7 is a roving machine 2.

Then, the control device restarts the machine based on the detection signals of the optical sensors 42 and 43 and the sensor 60.

Next, the operation of the device configured as described above will be described. During operation of the roving machine 2, the pipe replacement device 47 interferes with the empty bobbin E when ascending, as shown in FIG. 12, where the tips of the forks 30 and 31 are near the bottom of the empty bobbin E suspended on the bobbin carrier 7. The empty bobbin E or the full bobbin F does not interfere with the empty bobbin E when loading and unloading the bobbin carrier 7. This position is a position that does not interfere with the roving machine 2 when the forks 30, 31 are arranged at the lowest position together with the support plate 50, and is opposed to a position close to the roving machine 2.

Then, a pipe replacement operation is started based on the full-fill command, and the motor 19 is driven to rotate in the reverse direction, so that the forks 30 and 3 are driven.
The support plate 50 is raised together with the support bracket 48 to a position where 1 is slightly lower than the flange 39 of the empty bobbin E. In this state, the forward / backward movement means 54 is moved forward, the drive rod 56 is moved forward (moves downward in FIG. 13), and each link 58 is rotated counterclockwise in FIG.

Is done. Next, the replacement arm back-and-forth moving means 54
Is moved forward and the forks 30 and 31 are
15 and the front bobbin hanging portion 36a is disposed at the third operating position corresponding to the flange 39 of the full bobbin F as shown in FIG. Bobbin rail 3 in that state
Is lowered, the bobbin wheel 4 is separated from the bottom of the full bobbin F, and the full bobbin F is hung by the bobbin hanging portion 36a on the front side. Next, the replacement arm back-and-forth moving means 54 is moved backward, and the forks 30 and 31 are arranged at the standby position.
The state shown by the solid line in FIG. Next, the motor 19 is driven in the reverse direction to raise the support plate 50. During the ascent, the pipe replacement arm longitudinal movement means 54 is moved forward, the support plate 50 is located at the second operating position, and the full bobbin F is moved to the bobbin hanger 6.
And it is in a state of facing. Then, in this state, the support plate 50 is moved to the highest position, and the state shown by the chain line in FIG. In this state, the full bobbin F is locked on the bobbin hanger 6.

Next, the exchanging arm fore-and-aft movement means 54 is moved backward, and the forks 30 and 31 are arranged at the standby position.
As shown by a solid line in FIG.
It is in a state of being hung. Next, the motor 19 is driven to rotate forward, and the support plate 50 is lowered to a state where it is arranged at the lowest position as shown by a chain line in FIG. Next, the tube changing arm front-rear movement means 54 is advanced, and the support plate 50 is arranged at the fourth operation position, and the empty bobbin E faces the bobbin wheel 4 as shown in FIG.
From this state, the bobbin rail 3 is lifted, the bottom of the empty bobbin E is fitted to the bobbin wheel 4, and the flange 39 of the empty bobbin E is raised from the bobbin suspension portion 36b. Next, the exchanging arm fore-and-aft movement means 54 is retracted to place the support plate 50 at the standby position, and FIG.
The state shown by the solid line in FIG. Then, from this state, the motor 19 is driven to rotate in the reverse direction, and the support plate 50 is raised, and the state shown by the chain line in FIG. The empty bobbin E
Is mounted on the bobbin wheel 4 and the support plate 50
Is arranged in the state shown by the solid line in FIG. 17B, the machine is restarted based on the detection signals of the optical sensors 42, 43 and the sensor 60.

In this embodiment, in addition to the effects (1), (2) and (5) to (10) of the first embodiment, the following effects can be obtained. (11) The bogie 24 is not present, and the support plate 50 for supporting the forks 30 and 31 and the like are in the roving mode during the machine operation.
The floor surface can be used effectively because it is arranged at a standby position above the floor.

(12) The horizontal movement range of the forks 30, 31 is limited to the forks 30, 31 and the bobbin wheel 4.
Is set between a position for transferring the full bobbin F or the empty bobbin E between the position and the close position that does not interfere with the roving machine 2. Therefore, the stroke amount of the forks 30 and 31 can be set to a necessary minimum, and the space occupied by the tube replacement device 47 can be reduced. Further, a mechanism for moving the forks 30, 31 back and forth (replacement arm fore-and-aft movement) can be reduced in size. Further, when the full bobbin F is hung on the forks 30, 31 and the forks 30, 31 are most advanced, the bending moment acting on the members supporting the forks 30, 31, etc. becomes small, so that each member is required. The strength can be reduced, and the manufacturing cost of the device can be reduced.

(13) Since the full bobbin F is hung on the bobbin hanging part 36a on the front side to perform the pipe replacement work, the empty bobbin F is hung on the bobbin carrier 7 and then the empty bobbin F is hung on the back side. An operation of mounting the bobbin E on the bobbin wheel 4 is performed.
Therefore, the time at which the bobbin carrier 7 on which the full bobbin F is suspended can be carried out is earlier than in the embodiment. Further, the amount of movement of the forks 30, 31 in a state where the full bobbin F is suspended from the forks 30, 31 is reduced, and the power consumption is reduced.

(14) Since the two rollers 51 supported by both support plates 53 move along the support frame 49,
Even if the full bobbin F is hung on the forks 30 and 31 and a large bending moment acts on the support plate 50, the front roller 51 abuts on the inner lower surface of the support frame 49, and the rear roller 51 is supported by the support frame 49. The support plate 50 is smoothly moved back and forth in a state where the support plate 50 is in contact with the inner upper surface of the support plate 49.

The embodiment is not limited to the above, and may be embodied as follows, for example. As shown in FIG. 18, the lower side of the front side portion of the fork body 35 is bulged to be thicker and the recess 37 is formed deeper. In this case, the empty bobbin E suspended from the front bobbin suspension portion 36a is suspended slightly lower than the full bobbin F suspended from the rear bobbin suspension portion 36b. Then, the entire peripheral surface of the flange portion 39 faces the wall surface 37a of the concave portion 37, and the effect of preventing shaking is improved. When the empty bobbin E suspended from the forks 30 and 31 is mounted on the bobbin wheel 4, the empty bobbin E is mounted on the bobbin wheel 4 even if the height of the flange portion 4 a is the same as in the above embodiment. In this state, the flange 39 of the empty bobbin E rises from the bobbin suspension 36a while the flange 39 of the full bobbin F is fitted to the bobbin suspension 36b. Therefore, with a simple modification of only the fork main body 35, the effect of preventing the bobbin suspended on the front bobbin suspension part 36a from swinging is improved.

The fork body 35 may be manufactured by pressing or cutting instead of casting. ○ Forks 30 and 31 are connected to fork body 35 and support plate 3
3a and 33b may be formed integrally with one plate.

The concave portion 38 of the bobbin hanging portion 36b on the back side
Also, a rubber magnet 41 may be provided. Also, the recesses 37, 3
The rubber magnet 41 may be omitted from FIG. In the first and second embodiments, instead of starting the refilling operation based on the full-package signal, the starting time of the refilling operation is set to a predetermined time approaching full filling. The predetermined time is longer than the time required for the fork 30, 31 to move to the position where the full bobbin F is suspended after the start of the pipe replacement operation. It is set so that the time required to descend to is slightly shorter. In this case, compared to the case of the first or second embodiment, the time from the standstill of the machine to the completion of the pipe replacement work is shorter.

In the pipe replacement device according to the second embodiment, after the bobbin carrier 7 having the empty bobbin E suspended thereon is carried into the support rail 5, the empty bobbin E is transferred to the fork 3 before being full.
It may be suspended at 0, 31 and stand by at the standby position. In this case, only the total time of the work time for removing the empty bobbin E from the bobbin hanger 6 and suspending it on the forks 30 and 31 after the start of the pipe replacement work and the time required for the reciprocating movement from the standby position to the highest position. The replacement work time can be reduced.

In the pipe replacement device of the first embodiment, the empty bobbin E is suspended on the bobbin suspension 36b on the back side and the full bobbin F is suspended on the front bobbin as in the case of the second embodiment. The pipe replacement operation may be performed such that the pipe is suspended on the suspension portion 36a. In this case, if the lifting device 9 and the bogie 24 are operated during the operation of the roving machine 2 and the bogie 24 is made to stand by at the standby position while the empty bobbin E is suspended by the forks 30 and 31, Similarly, it is possible to shorten the time required for the replacement operation.

In the pipe replacement device of the second embodiment, the full bobbin F is hung on the bobbin hanging portion 36b on the back side and the empty bobbin E is hung on the front bobbin as in the first embodiment. The pipe replacement operation may be performed such that the pipe is suspended on the suspension portion 36a. In this case, the restart time of the machine can be earlier than in the second embodiment.

In the second embodiment, instead of the Scott Russell linear motion mechanism, the support plate 50 may be moved by a ball screw mechanism as the pipe replacement arm longitudinal movement means 54. For example, the right and left support frames 4
9, a ball screw mechanism is disposed along the support frame 49, and a support plate 50 is connected to each ball nut via a connecting plate.
Concatenate. Then, both screw shafts are driven by independent motors in a state synchronized with each other.

The detecting means for detecting that the empty bobbin E has been delivered to the bobbin wheel 4 at the time of the pipe replacement work includes:
An ultrasonic sensor may be used instead of the two sets of transmission type optical sensors 42 and 43. For example, the empty bobbin E mounted on the bobbin wheel 4 on the frame side of the roving machine 2
The empty bobbin E moves the bobbin wheel 4 according to the time until the ultrasonic wave is transmitted toward the
Detects that it has been attached to

The operation of taking out the full bobbin F from the roving machine 2 and the operation of attaching the empty bobbin E to the bobbin wheel 4 are automatically performed. The suspension of the full bobbin F on the bobbin hanger 6 and the removal of the empty bobbin E are performed. May be performed by a user. For example, in the first embodiment, the support rail 5 is moved up (standby position) shown in FIG.
And the like, the bottom of the empty bobbin E can be moved to two positions, a lower position slightly above the forks 30, 31. Then, the operator moves the empty bobbin E suspended from the bobbin carrier 7 of the support rail 5 disposed at the lowered position to the bogie 24.
After the work of suspending the bobbin F on the forks 30 and 31, the bogie 24 is operated to take out the full bobbin F from the roving machine 2.
Then, the worker hangs the taken-out full bobbin F on the bobbin hanger 6 of the bobbin carrier 7. Thereafter, the support rail 5 moves to the ascending position, and the bogie 24 moves forward and backward to mount the empty bobbin E on the bobbin wheel 4. In this case, there is no need to work in a bent posture, which places a heavy burden on the operator, and the lifting control of the lifting device 9 is simplified.

The refilling device is not limited to a device that takes out the full bobbin F or mounts the empty bobbin E to the bobbin wheel 4 all at once. It may be applied to a wagon-type refilling device that performs refilling work.
