2. Description of the Related Art In spinning machines, especially ring spinning machines, roving is pulled out from a roving winding suspended from a creel and supplied to a draft part below. As the roving continues to be supplied to the draft part and the roving winding becomes empty or near empty, it is necessary to replace it with a new roving winding. or roving the
Alternatively, it is necessary to insert the roving wound into the draft part of the spinning machine again.

In order to save labor in the spinning process, a roving change machine (Shino exchange machine) was proposed that sequentially performs the roving splicing work and roving change work from one end of the spinning machine frame (Japanese Patent Application Laid-Open No. 1983-1999). 5
7957, etc.), and has also been implemented. In this type of roving changing machine, the end of the roving is taken out by suction from a full bobbin (preliminary roving) for new replacement, and then the end of the roving is spun by a roving splicing device. Perform the work of splicing the roving to the inner roving. At that time, in order to make the length of the roving end protruding from the gripping part of the roving splicing device almost constant, a part of the roving thread that has been introduced is cut off, and a cotton collection box installed in the roving changer is installed. (cotton collection room), and when the cotton collection box is full of rovings, an operator manually removes the rovings in the cotton collection box.

0004

[Problem to be solved by the invention] However, since many spinning machines are installed in a narrow space in a spinning factory, there is a demand for a small roving changer, and the cotton collecting machine installed in the roving changer is required to be small. The volume of the box is also small. Since the roving supplied to the spinning frame becomes thick when spinning a thick count, when the roving changing machine performs roving changing work on one spinning frame, the roving is left in the cotton collecting box. When the box becomes full, the number of times the operator has to take out the roving from the cotton collection box increases, resulting in a reduction in work efficiency. In addition, when the roving yarn is collected from inside the cotton collecting box, especially when the roving yarn is made of 100% cotton containing a large amount of short fibers, a large amount of scattered fibers are generated and the work environment is not good.

The present invention has been made in view of the above-mentioned problems, and its first purpose is to completely automatically collect the roving from the cotton collecting chamber installed in the roving changing machine. The second purpose is to provide a cotton collection device for a roving changer that can perform the same operations, even when the rovings collected from the collection chamber of the roving changer are manually collected. It is an object of the present invention to provide a cotton collection device for a roving changer that can reduce the number of operations.

A discharge hole 21 a is formed at the tip of the discharge pipe 21 on the outer end (OE) side of the spinning frame frame 1 . Further, the base end of the discharge pipe 21 is equipped with a shutter (not shown) that can be opened only toward the discharge hole.
The suction action by the intake fan 16 is prevented from acting on the discharge hole 21a.

In order to prevent the fleece sent out from the draft part 7 from having an adverse effect on weights other than the thread cutting weight when the thread breaks during operation, the spinning frame frame 1 is provided with a device that reliably sucks up the fleece when the thread breaks. In addition, a pneumatic clearer (not shown) is equipped to remove fluff adhering to the front bottom roller during normal operation. A pneuma box 22 is provided. In addition, a concentrated cotton collection duct 23 is installed on the ceiling on the out-end (OE) side of the spinning machine frame 1, and the pneumatic box 22 is connected to the duct 24.
It is connected to the concentrated cotton collection duct 23 via. A valve 25 is provided in the middle of the duct 24 to control the suction action of the concentrated cotton collection duct 23 to the pneuma box 22.

A suction removal pipe 26 serving as removal means is connected to the duct 24 closer to the concentrated cotton collection duct 23 than the valve 25 . The suction removal pipe 26 exerts a suction action into the roving collection box 17 through the discharge pipe 21, and suctions and removes the rovings in the roving collection box 17. The suction removal pipe 26 is bifurcated, and its tip side extends horizontally toward the spinning machine frame at a height corresponding to the discharge hole 21a. As shown in FIG. 5, the end face of the inlet 26a of the suction removal pipe 26 is formed into an arcuate side surface, and is covered by a door 27 that opens and closes automatically. As shown in FIGS. 5 and 6, the door 27 is rotatably supported by a shaft 28 at its base end, and has a cover portion 27a formed at its tip end in sliding contact with the end surface of the inlet 26a of the suction removal pipe 26. An engagement surface 27b having an inclination of approximately 45 degrees is formed on the front surface of 27a. When the discharge pipe 21 moves toward the suction removal pipe 26, the upper end of the discharge pipe 21 engages with the engagement surface 27b of the door 27 and moves in that state, as shown in FIG. The door 27 is rotated from the closed position to the open position shown by the chain line.

Next, the operation of the apparatus constructed as described above will be explained. The roving changer 12 is mounted on both the left and right sides of the transport vehicle 13 and is transported to a position corresponding to the spinning frame frame 1 that requires roving changing work, and at that position, the roving change machine 12 is moved from the transport vehicle 13 to the spinning frame frame 1 side. The machine then moves along the rails 14 extending on both the left and right sides of the spinning machine frame 1 to sequentially perform roving changing work and roving splicing work.

During the roving change operation, as shown in FIG. 3, the suction nozzle 19 of the roving thread pick-up device is moved to a pick-up position corresponding to the lower end of the full bobbin F, and the end of the roving thread R is sucked from the full bobbin F. and interject. The ends of the rovings R that have been sucked into the suction nozzle 19 more than necessary during pick-up are cut by the roving cutting member, and the cut rovings R are stored in the roving collection box 17 through the suction pipe 18. be done. After the roving change operation is completed, the drive of the intake fan 16 is stopped, and the roving change machine 1
2 is moved to a predetermined position corresponding to the suction removal pipe 26 disposed on the out-end OE side of the spinning frame frame 1. When the roving changer 12 moves to a predetermined position, the inlet 26a of the suction removal pipe 26 is inserted into the discharge hole 21a of the discharge pipe 21, and the discharge pipe 21 and the suction removal pipe 26 are connected, as shown in FIG. . This allows the concentrated cotton collection duct 2
The suction action of 3 is the suction removal pipe 26 and the discharge pipe 21.
The roving R in the roving collection box 17 is sucked and removed through the discharge pipe 21 and the suction removal pipe 26 to the concentrated cotton collection duct 23. The rovings R are then conveyed to the raw cotton supply chamber by the concentrated cotton collection duct 23 and reused. When the roving changer 12 reaches the predetermined position, the valve 25 is closed by a detection signal from a detection sensor (not shown), and the suction action of the concentrated cotton collection duct 23 to the suction removal pipe 26 is strengthened, and the roving is collected. The suction removal of the rovings in the box 17 is ensured.

After a predetermined period of time (several seconds) has elapsed, the roving changer 12 starts moving toward the gear end, and after being loaded onto the transport vehicle 13 waiting at the gear end, the roving changer 12 starts moving toward the gear end, and is then loaded onto the transport vehicle 13 waiting at the gear end. It is transported to a position corresponding to the spinning machine stand, and the same action is repeated. Every time the roving changing machine 12 completes the roving changing work of one spinning frame frame 1, the roving in the roving collecting box 17 is automatically suctioned and removed.
The amount of roving accommodated in the roving becomes below a certain value, the suction force (air volume and static pressure) by the suction fan 16 does not decrease much, the suction action becomes stable, and suction errors during the pick-out operation are reduced.

Furthermore, in this embodiment, the rovings are suctioned and removed by using the concentrated cotton collecting duct 23 for the pneumatic device already installed in the spinning factory, so that the equipment cost is small. (Embodiment 2) Next, a second embodiment will be explained according to FIGS. 7 to 10. In this embodiment, the removal means for suctioning and removing the rovings in the roving collection box 17 of the roving changer 12 is provided on the gear end (GE) side of the spinning frame frame 1, as compared to the first embodiment. It is very different. The configuration of the roving changer 12 differs from the previous embodiment only in that the discharge pipe 21 is open above. A concentrated cotton collection duct 23 is disposed above the gear end (GE) side end. A suction removal pipe 29 is connected to the concentrated cotton collection duct 23 at a position corresponding to the discharge pipe 21 when the roving changer 12 is mounted on the transport vehicle 13. The suction removal pipe 29 is provided with a bellows portion 29a in the middle, and a valve 30 is provided near the upper end. Further, an air cylinder 31 is disposed at a position corresponding to the suction removal pipe 29 so as to extend in the vertical direction via a bracket 32, and the lower part of the suction removal pipe 29 is fitted into the tip of the piston rod 33. A support bracket 34 is fixed thereto. Then, due to the expansion and contraction of the piston rod 33, the suction removal pipe 29
However, the position where the discharge pipe 21 can be connected and the discharge pipe 2
1 and a position spaced apart from the position shown in FIG.

In this embodiment, the valve 30 is always closed and the piston rod 33 of the air cylinder 31 is kept in a retracted state. After the roving changing machine 12 finishes changing the roving of the spinning frame 1 in the same manner as in the above embodiment,
When it returns to the position corresponding to the carrier vehicle 13, the air cylinder 31 is activated and the piston rod 33 protrudes, as shown in FIG.
A suction removal pipe 29 is connected to the discharge pipe 21 as shown in FIG. In this state, the valve 30 is opened, and the rovings in the roving collection box 17 are suctioned and removed by the suction action of the concentrated cotton collection duct 23 via the discharge pipe 21 and the suction removal pipe 29.

(Embodiment 3) Next, a third embodiment will be explained with reference to FIG. In this embodiment, in the second embodiment,
The discharge pipe 21 side of the roving changer 12 is configured to be expandable and retractable,
The difference is that the suction removal pipe 29 side is fixed at a predetermined position. That is, the lower end of the suction removal pipe 29 is fixed at a predetermined position by the bracket 32. Further, an air cylinder 35 is fixed to the upper part of the roving changer 12, and a discharge pipe 21 is connected to the piston rod 36 of the support bracket 3.
It is fixed via 7. A bellows portion 21b is formed on the discharge pipe 21 so that it can expand and contract.

In this embodiment, as in the second embodiment, after the roving changing machine 12 has returned to the position corresponding to the transport vehicle 13 after completing the roving changing work on the spinning frame frame 1, the air cylinder 35 is activated. When activated, the discharge pipe 21 is connected to the suction removal pipe 29 . Then, the valve 30 is opened and the rovings in the roving collection box 17 are suctioned out. In the second embodiment, since the suction removal pipe 29 side is configured to be expandable and retractable, it is necessary to provide an air cylinder 31 at the gear end (GE) side end of each spinning machine frame 1 for expanding and contracting the suction removal pipe 29. There is. However, in this embodiment, since the discharge pipe 21 side expands and contracts, by simply providing one air cylinder 35 in the roving changer 12, the suction removal pipe 29 can be moved to any position corresponding to any spinning machine frame 1. Connection with the discharge pipe 21 is possible, the number of air cylinders is reduced, and the control circuit for operating the air cylinders is also simplified.

(Embodiment 4) Next, a fourth embodiment will be explained with reference to FIG. In each of the embodiments described above, removal means for removing the rovings in the roving collection box 17 of the roving changer 12, that is, suction removal pipes 26 and 29, were provided at each end of each spinning frame frame 1. On the other hand, this embodiment differs greatly from the previous embodiments in that the number of removing means is smaller than the number of spinning frame frames 1. That is, in this embodiment, one suction removal station 38 equipped with a suction removal pipe (not shown) having the structure of the second or third embodiment is provided for every three spinning frame frames 1. It is set in. Further, on the roving changer 12 side, a discharge pipe 21 having a structure corresponding to the suction removal pipe provided in the suction removal station 38 is provided. Then, when the roving changer 12 is moved to a position corresponding to the suction removal station 38, the rovings in the roving collection box 17 are removed by suction in the same manner as in the second or third embodiment. will be held.

When the roving changing machine 12 performs one roving changing operation (one spinning machine), the amount of roving R stored in the roving collecting box 17 depends on the count of the spun yarn. Differently, in the case of thick-count spinning, the roving collection box 17 becomes full after changing the roving once or twice, and in the case of fine-count spinning, the roving collecting box 17 becomes full after changing the roving several times. becomes. Therefore, in the case of fine count spinning, it is not necessary to remove the rovings in the roving collecting box 17 every time one or two roving changing operations are completed, and the roving changing machine 12 is connected to the suction removal station 38. When the roving is moved to the corresponding position, the roving in the roving collection box 17 is removed by suction.

In addition, in the case of thick-count spinning, it is necessary to remove the roving in the roving collecting box 17 every time one or two roving changing operations are completed; If the roving thread change operation is continued without suctioning and removing the threads, the suction efficiency will decrease and mistakes will occur in picking out the ends of the roving threads. In order to avoid this inconvenience, in the case of thick-count spinning, after one or two roving changes have been completed, the spinning frame is moved to the position corresponding to the spinning frame 1 that requires the next roving change. Beforehand, the roving changer 12 is transported by the transport vehicle 13 to a position corresponding to the suction removal station 38 . After the suction removal of the rovings in the roving collection box 17 is completed, the rovings are transported to a position corresponding to the spinning frame frame 1 that requires the roving replacement work, and the roving replacement work is performed. The time required for transporting the roving changer 12 by the transport vehicle 13 to the position corresponding to the suction removal station 38 or a predetermined spinning frame frame 1 is short, and the time required for the suction removal work is also short. There is no risk of interfering with the operation of the spinning machine stand 1.

Note that the roving changing machine 12 is provided with a counter for counting the number of roving changing operations, and when the number of roving changing operations reaches a predetermined value that requires removal of the roving in the roving collection box 17. At this time, the transport vehicle 13 may transport the roving changer 12 to a position corresponding to the suction removal station 38 in response to a signal from the counter, and perform suction removal. In this case, the number of suction removal stations 38 can be reduced. Since the predetermined value described above varies depending on the spinning conditions, it is preferable to use a variable set value for the counter. Further, the installation position of the suction removal station 38 may be a position that does not correspond to the spinning frame frame 1.

(Embodiment 5) Next, a fifth embodiment will be explained with reference to FIGS. 13 to 15. In this embodiment, the roving stored in the roving collection box 17 of the roving changing machine 12 is temporarily transferred to the transport vehicle 1.
This differs greatly from the previous embodiments in that the cotton is stored in the cotton collection chamber provided in No. 3 and then removed by suction using a suction removal means. An intake fan 40 driven by a motor 39 is provided above the cotton collecting chamber 41 near the spinning machine frame 1 of the transport vehicle 13. The cotton collection chamber 41 is the roving collection box 1 of the roving changing machine 12.
7, and the cotton collection chamber 41 is equipped with a roving changer 1.
A discharge pipe 42 as an expandable communication means connected to the second roving collecting box 17 and a connecting suction pipe 43 as a connectable suction means are connected to the left and right sides thereof in a horizontally extending state. Furthermore, a discharge pipe 44 serving as a communication means for communicating the cotton collecting chamber 41 with the outside is disposed at the upper part of the cotton collecting chamber 41 so as to extend upward. or,
An air cylinder 45 is fixed to the lower part of the roving changer 12 at a position corresponding to the connecting suction pipe 43, and an air cylinder 45 is fixed at a position corresponding to the connecting suction pipe 43.
2 is the piston rod 46 of the air cylinder 45.
It is fixed to via a support bracket 47.

A concentrated cotton collecting duct 23 is disposed above the gear end (GE) side end, and the concentrated cotton collecting duct 23 has a pipe similar to that of the second embodiment at a position corresponding to the discharge pipe 44. A suction removal pipe 29 having the configuration shown in FIG. and a position where the suction removal pipe 29 can be connected to the discharge pipe 44 by expansion and contraction of the piston rod 33;
It is arranged to be moved to a position spaced apart from the discharge pipe 44. Note that the suction removal pipe 29 is not provided for each spinning frame 1, but is provided at one location for a plurality of spinning machines.

In this embodiment, the roving changing machine 12 moves the transport vehicle 13 after completing the roving changing work of the spinning frame frame 1, as in the previous embodiment.
After returning to the position corresponding to , the air cylinder 45 of the roving changer 12 is activated and the piston rod 46 is protruded.
A discharge pipe 42 is connected to a connecting suction pipe 43. Next, the suction fan 40 of the transport vehicle 13 is driven, and due to its suction action, the rovings in the roving collection box 17 are drawn into the cotton collecting chamber 41.
After the suction removal is completed, the piston rod 46
is pulled in, and the connection between the discharge pipe 42 and the connecting suction pipe 43 is released. This work only needs to be done before the roving changing machine 12 starts the next roving changing operation, and while the spinning machine frame 1 is being transported by the transport vehicle 13 to the position corresponding to the spinning frame 1 that requires the roving changing operation. The roving change operation can be started immediately after arriving at the roving change machine table.

The rovings collected in the cotton collection chamber 41 of the transport vehicle 13 are discharged as appropriate during the operation of the roving changing machine 12. With the carrier vehicle 13 stopped at a position corresponding to the suction removal pipe 29, the air cylinder 31 is operated, and the piston rod 33
protrudes, and the suction removal pipe 29 is connected to the discharge pipe 44. Next, the valve 30 is opened, and the rovings in the cotton collection chamber 41 are suctioned and removed by the suction action of the concentrated cotton collection duct 23 via the discharge pipe 44 and the suction removal pipe 29.

Since the volume of the cotton collection chamber 41 of the transport vehicle 13 can be made much larger than that of the roving collection box 17 of the roving changer 12, the suction and removal work of the rovings in the cotton collection chamber 41 can be performed easily. The number of times is smaller than in each of the above embodiments. Although the time required for one suction removal operation is longer than in each of the above embodiments, the suction removal operation can be performed while the roving changer 12 is in operation. Alternatively, the suction removal pipe 29 may be installed at one or two locations and moved to the installation locations to perform the suction removal operation during the waiting time for the roving change operation of the roving changer 12. Note that when the transport vehicle 13 is provided with the discharge pipe 44 connected to the suction removal pipe 29 as in this embodiment, the discharge pipe 21 connected to the suction removal pipe 29 is installed in the roving changer 12.
The number of suction removal pipes 29 is reduced to 1 compared to the case where
/2.

(Embodiment 6) Next, a sixth embodiment will be explained with reference to FIG. In this embodiment, the configuration of the roving changing machine 12 remains the same, but the difference from the fifth embodiment is that the operator collects the roving in the cotton collection chamber 41 provided in the transport vehicle 13. ing. That is, the cotton collection chamber 41 is disposed on the opposite side of the transport vehicle 13 from the position facing the gear end (GE), and the connecting suction pipe 43 is extended accordingly. In addition, there is a door 4 in the cotton collection room 41 that can be opened and closed manually.
8 is provided.

In this embodiment, the rovings in the roving collecting box 17 of the roving changer 12 are suctioned and removed into the cotton collecting chamber 41 in the same manner as in the fifth embodiment. Then, the operator collects the rovings accumulated in the cotton collection chamber 41 as appropriate. Since the volume of the cotton collection chamber 41 of the transport vehicle 13 can be made much larger than that of the roving collection box 17 of the roving changing machine 12, the number of times the roving in the cotton collection chamber 41 is collected is lower than before. It will be much less. Further, the recovery operation can be performed even during the roving changing operation of the roving changing machine 12.

(Embodiment 7) Next, a seventh embodiment will be explained with reference to FIGS. 17 and 18. In this embodiment, the discharge pipe 21 of the roving changing machine 12 is connected to the pneumatic box 22 provided on the spinning frame frame 1, and the roving in the roving collecting box 17 is collected. This is different from the example. That is, the roving changer 12 has a discharge pipe 21 (not shown) having a discharge port at a position facing the pneumatic box 22 when the roving changer 12 stops at the outer end OE of the spinning machine frame 1. It is arranged so that it can move forward and backward with respect to the spinning frame frame 1 by the action of an air cylinder. Further, a side wall of the pneuma box 22 is provided with an openable and closable connection hole 50 into which the discharge port of the discharge pipe 21 is inserted. In this embodiment, the pneuma box 22 serves as the removal means.

In this embodiment, when the roving changer 12 reaches the outer end OE of the spinning frame 1, the running is stopped and the discharge pipe 21 is connected to the connection hole 50 of the pneumatic box 22.
connected to. Then, the valve 25 is opened, and the rovings in the roving collection box 17 are discharged through the discharge pipe 21 to the pneuma box 22, and are suctioned and removed through the duct 24 into the concentrated cotton collecting duct 23.

(Embodiment 8) Next, an eighth embodiment will be described with reference to FIG. In this embodiment, a cotton collection box 51 as another cotton collection chamber is installed at the out end OE end of the spinning frame 1, and the discharge pipe 21 of the roving changer 12 is connected to the cotton collection box 51.
This differs from the previous embodiments in that the rovings in the roving collecting box 17 are collected by connecting to the roving collecting box 17.

In this embodiment, when the roving changer 12 stops at the outer end OE of the spinning frame frame 1, the discharge pipe 2
1 is connected to the cotton collection box 51. Then, the suction fan 16 in the roving collection box 17 is reversed to feed the roving in the roving collection box 17 to the cotton collection box 51.

Effects of the Invention As described in detail above, according to the present invention, the roving temporarily stored in the cotton collection chamber equipped in the roving changing machine is periodically and automatically suctioned and removed. Since the amount of roving stored in the cotton collection chamber of the yarn changing machine is controlled to be below a certain value, the suction force does not decrease much and the suction action is stabilized, reducing suction errors during pick-up work. Furthermore, the cotton collection chamber of the roving changer can be made smaller, and the intake fan can be made smaller, reducing power consumption.

Furthermore, in the invention described in claims 2 and 3, the work of collecting the roving stored in the collecting chamber of the roving changing machine is performed completely automatically, and the roving is removed by the operator. Collection work is eliminated, resulting in labor savings. Further, in addition to the above-mentioned effects, the invention described in claim 3 reduces the number of collection operations to the concentrated collection duct, and the number of installation locations for the suction removal pipe can be further reduced.
