Description

Detailed Description of the Invention (Industrial Application Field) The present invention suspends roving windings in two rows, front and rear, from a creel, and also suspends roving windings carried into a preliminary roving rail extending above the front side of the creel. The present invention relates to a method and apparatus for carrying in preliminary roving in a spinning machine, in which a roving exchange operation with a bobbin winder is carried out every other row along the longitudinal direction of the spinning frame using a roving machine.

(Prior Art) In a spinning frame, roving is pulled out from a roving thread suspended from a creel at a high position and is supplied to a draft bar located below. Then, as the supply of roving to the draft bar progresses and the roving winding becomes empty or nearly empty, it is necessary to replace it with a new roving winding. However, the rovings are hung higher than the worker's height, and in recent years the booth has been reduced to 3.
K (around 1), and each spinning machine requires 400 pieces, making the roving work a chore for workers.Therefore, automation of the roving changing work has been proposed. In the roving changing method using a roving changing machine, when spinning rovings of the same size are suspended from the front or rear rows of the creel, the maximum diameter of the rovings should be less than or equal to the bobbin hanger pitch of the creel. As a result, there is a problem in that the large packaging of roving is regulated by the value of the creel bobbin hanger pitch.For example, Japanese Patent Laid-Open No. 62-62928 discloses a method for solving this problem. 1
As shown in Figure 1, spinning is started with full roving windings and medium roving windings S suspended in every other row from the two rows of bobbin hangers at the front and rear of the creel, and after the spinning has progressed, the spinning is suspended. A method has been proposed in which the roving winding S that approaches the end of the roving is sequentially replaced with the preliminary roving winding F that has been carried into the preliminary roving winding rail in advance.

(Problems to be Solved by the Invention) In the conventional roving changing method, when the number of preliminary roving turns suspended on the preliminary roving winding rail is the same as the number of roving turns suspended in one row of creels, As shown in FIGS. 11(a) and 11(b), when changing the roving thread in the odd row 1] and when changing the roving thread 114 in the even row
As a result, the position of the preliminary roving winding suspended on the preliminary roving winding rail is shifted by one pitch. Therefore, for both odd and even rows, the number of roving turns on the preliminary roving rail is one more than the number of rovings for one row of creel (! In this way, the rovings 117 in the odd rows are changed two by two in order from the spare roving windings placed at the right end in FIG. When changing rovings, two rovings are changed starting from the second roving winding from the right, and can be used for both odd and even rows. In a configuration in which one more spare roving roll is carried in than the roving roll, the spinning process and the roving culm are directly connected by a conveyor rail, and the roving roll doffed by the roving machine is directly transferred to the spare roving roll as a spare roving roll. When adopting a system in which the roving is carried into the roving, there is a problem in that the one spare roving that remains when the roving is changed becomes a hindrance to smoothly doffing the roving in the roving process.

The present invention has been made to solve the above-mentioned problems, and its purpose is to suspend roving threads in two rows in the front and back from a creel, and to connect the roving threads with the preliminary roving windings carried into the preliminary roving winding rail. In a spinning machine that performs yarn H work on every other row, the spinning process and roving process are connected by a conveyance path, and the roving roll doffed in the roving process is carried directly to the preliminary roving winding rail. It is an object of the present invention to provide a preliminary roving carrying method and loading amount that can smoothly carry out yarn change work and doffing work in a roving process.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention, a preliminary roving winding rail and a conveyance path continuous with the rail are moved, and at a predetermined interval, the same number of roving windings as one row of creel is The transport body with the spare roving winding suspended thereon is moved so that its stopping position is one of the creel's roving winding rows from the stopping position at the time of the previous roving change operation.
The roving is carried into the preliminary roving rail so that the position is shifted by the pitch.

In addition, as a preliminary roving carrying device, a preliminary roving winding rail is provided on the front side of the creel from which roving windings are hung in two rows, front and rear, and the preliminary roving winding rail is carried in to the rail. A carrier machine is used in which the same number of spare roving windings as the number of roving windings for one row of creels are hung at predetermined intervals on a conveying body that moves on a continuous conveying path, and the conveying body is connected so as to be removable. At Glj 11, while the roving Vi machine performs the roving change operation every other row along the longitudinal direction of the spinning frame frame,
A movable body is provided at a predetermined position at the end of the preliminary roving winding rail on the conveyor loading side, the movable body being movably disposed along the rail and reciprocated between an operating position and a standby position by a drive device. The movable body has an engagement lever that engages with an engagement portion provided at a predetermined position of the conveyance body.When the movable body is placed in a standby position, the engagement lever is placed in a retracted position, and when the movable body moves forward, the engagement lever engages with an engagement portion provided at a predetermined position of the conveyance body. They are each movably arranged in an engagement position where they can be engaged with each other.

(Function) In the preliminary roving carrying method of the present invention, the creel 1 is
I hung the same number of spare rovings as the rows of rovings! ! 22 The roving is carried in so that its stopping position is shifted by one pitch of the roving winding row of the creel from the stopping position during the previous roving change operation, and the roving of odd rows or even rows is transported. The arrangement position of the preliminary roving winding is changed accordingly.

In addition, in the invention described in the second claim, the conveying body suspending the same number of secondary roving windings as the roving windings for one row of C creels at a predetermined interval is always moved to a predetermined position on the preliminary roving winding rail by the @ machine. The rovings are also carried into a suitable position when changing the rovings in either the odd or even rows. Then, when the movable body is moved back and forth by the drive device, the engaging lever engages with the engaging portion of the conveying body to move the entire conveying body from one position to another. This is done by moving the roving winding row of the creel by one pitch.

(Example 1) A first example embodying the present invention will be described below with reference to FIGS. 1 to 5. As shown in FIG.
On one side (only one side shown), a preliminary roving winding rail 2 is provided extending along the creel, and the preliminary roving winding rail 2 is connected to a main conveyance rail 3 as a conveyance path continuous to the roving process (not shown) via a branch part 3a. are connected. Each rail 2.3 is formed with an opening in cross section, and is used to suspend the preliminary roving winding [or the roving bobbin after being used in the spinning machine frame 1] and transport the roving bobbin between the roving and spinning processes.

As the engagement lever 18 rotates, the positioning lever 17 is reciprocated between an engagement position where it engages with an engagement row 56 serving as a positioning engagement portion and a retracted position where it disengages from the roller 6. It looks like this. The rotating shaft 16 is supported so as to pass through a block 20 fixed to the preliminary roving winding rail 2, and has a holding lever in the middle thereof that holds the positioning lever 17 in the engaged position and the retracted position. Structure (not shown)
is provided. On the side of the preliminary roving winding rail 2 there is a first
．． As shown in FIG. 3, when the positioning lever 17 is rotated to the engagement position with the engagement roller 6, a stopper 21 that prevents the lever 17 from rotating further from the same position is attached to the engagement lever 18. is fixed in a position where it can be engaged with. or,
When the positioning lever 17 is rotated from the engagement position to the retracted position, a stopper 22 for preventing the positioning lever 17 from further rotating beyond the retracted position is attached to the lever 19.
is fixed in a position where it can be engaged with.

A support shaft 23 is provided closer to the main transport rail 3 than the rotation shaft 16, and a separation lever 24 for releasing the connection between the transport body 4 and the coupling body 12 is attached to the support shaft 23 at the base end thereof. It is rotatably supported. A lever 25 for interlocking the positioning lever 17 and the separation lever 24 is fitted to the upper end of the rotation shaft 16 so as to be integrally rotatable, and a lever 25 extending substantially parallel to the separation lever 24 is attached to the tip of the lever 25. A narrow end of an operating lever 27 is connected to the guide pin 26 through an elongated hole 27a, and has an engaging protrusion 27b at one end thereof that can be engaged with the separation lever 24. The separation lever 24 is the positioning lever 17
When the actuating lever 27 is disposed at the engagement position with the engagement roller 6, the engagement with the engagement protrusion 27b of the operating lever 27 is released, and it is rotated downward by its own weight and engaged with the hook 10 of the conveyor 4. The hook 10 is rotated to the open position. As shown in FIG. 4, the preliminary roving winding rail 2 is formed with through holes 2a and 2b through which the positioning lever 17 and the separation lever 24 can enter into the rail.

On the active side (left side in Figure 1) of the spinning frame frame 1, the carrier 4 carried into the preliminary roving winding rail 2 is moved in cooperation with a positioning lever 17 to avoid any hindrance to the roving change operation. A 9A device 28 with a press is provided to hold it in a predetermined position so that it does not come. The pressing force device 28 is composed of an air cylinder 29 provided along the longitudinal direction of the preliminary roving winding rail 2, and a pressing member 30 fixed to the tip of the piston rod 29a, and is capable of adjusting the supply air pressure. The pressing force can be changed.

Next, a method for introducing a preliminary roving using the apparatus configured as described above will be explained. When performing roving change work on the roving windings S suspended on the odd-numbered row side, the carrier 11 moves the branch section 3a corresponding to the preliminary roving winding rail 2 that requires the transporting body 4 into the conveying body 4. After the last part of the transporter 11 has passed through, a sensor installed in the rear transporter 11 detects a stop position display member provided at a predetermined position and stops, and then the rearmost transporter 11 passes by 1!1gl as shown in Fig. 1(a).
111 moves backward, and the carrier 4 and the connecting body 12 are carried into the preliminary roving rail 2. When the transport body 4 starts to be carried in, the positioning lever 17 of the connection/disconnection device 14 is placed in a retracted position in which the engagement roller 6 cannot be engaged;
The separation lever 24 is disposed at a retracted position where it does not engage with the engagement protrusion 27b of the operating lever 27 and prevent the engagement roller 6 from passing. Therefore, the carrier 4 is smoothly carried into the preliminary roving winding rail 2 as the carrier 1f111 retreats. At this time, the roller 32 mounted on the coos 31 suspended from the rear of the coupling body 12 is held in a retracted position where it cannot engage with the engagement lever 18, and the roller 32 passes below the engagement lever 18. . When the roller 32 passes below the engagement lever 18, the WiIll stops and enters the state shown in FIG. . Next, when the 111fi11 moves forward, the roller 32 engages with the engagement lever 18 of one of the connection and disconnection devices 14 disposed near the main transport rail 3, and from this state, the m machine 11 moves further forward. As a result, the engagement lever 18 is rotated clockwise from the state shown in FIG. 1<a>, and the positioning lever 17 is also integrally rotated clockwise. At this point, the connector 12
Since the connection between the transport body 4 and the transport body 4 is not released, the transport body 4 also moves integrally with the coupling body 12. When the coupling body 12 moves to the point where the engagement between the roller 32 and the engagement lever 18 is released, the positioning lever 17 moves into its fitting recess 17a.
is engaged with the engagement [1-ra 6] provided at the rearmost portion of the conveyor 4. Also, at this time, the separation lever 24 is disengaged from the engagement protrusion 27b of the operating lever 27, rotates downward due to its own weight, and engages with the hook 10 provided at the rear of the carrier 4. At the same time, the hook 10 is rotated to a position where it is released from the locking pin 13 of the connecting body 12.

Then, as the Wi machine 11 moves further forward, the carrier 4 is separated from the connecting body 12 and remains within the preliminary roving winding rail 2, as shown in FIG.
2 to the position where the transport body 4 needs to be carried out.

The conveyor body 4 separated from the connecting body 12 is pressed and urged toward the gear end side by the pressing and urging device 28 provided on the outer end side, and the engagement row 56 at the other end is held in a predetermined position by the positioning lever 17. and is placed in a predetermined position suitable for odd row roving table operations.

On the other hand, when carrying in the preliminary roving winding F prior to the work on the even-numbered rows of roving stands, the carrier 11 controls the position of the spare roving winding rail 2 of the spinning machine stand that needs to be carried from the machine Then, upon receiving an instruction to carry the machine to the east side, it moves to a position corresponding to the spare roving winding rail 2. Then, in the same manner as described above, the carrier 4 is carried into the preliminary roving winding rail 2 from its rear side.

Then, when the case 31 moves to a position corresponding to the other connection and disconnection device 14 disposed at the back of the preliminary roving winding rail 2, the carrier 11 stops, and the O-ra 32 is connected to the engagement lever 18. The #li carrier 11 placed in the engageable position starts moving forward. Then, in the same way as above, 11 aircraft 1
1, the O-ra 32 and the engagement lever 18 engage with each other, and similarly to the above, the positioning lever 17 engages with the engagement row 56 provided at the forefront of the conveyor 4 and stops at a predetermined position. At the same time, the carrier 4 is separated from the connecting body 12, and the first
Figure (C) shows the acceptance state. In this state, the preliminary roving winding F suspended from the conveyor 4 is in a suitable position for the even-numbered rows of roving stands.

In addition, when carrying out the carrier 4 from the preliminary roving rail 2, the carrier 11 moves backward by 91, the connecting body 12 enters the preliminary roving rail 2, and the rear end of the connecting body 12 When the m mechanism 1 continues to move back and forth from the state in which the m mechanism 1 is in contact with the front end of the carrier 4, the carrier 4 moves to the left (preliminary roving rail 2) from the position shown in FIGS. 1(b) and 1(C). move to the back side). As a result, the positioning lever 17 is rotated clockwise, and the engagement between the fitting recess 17a and the engagement roller 6 is released. On the other hand, when the positioning lever 17 is rotated, the operating lever 27 is moved via the lever 25, and its engagement protrusion 27b engages with the separation lever 24, thereby causing the separation lever 24 to engage with the hook 10. It is rotated upward from this position and moved to a retracted position that allows each engagement roller 6 of the conveyance body 4 to pass therethrough. As a result, the hook 10 engages with the hooking pin 13, and the connecting body 12 and the conveying body 4 are connected. Next, as the carrier 11 moves forward, the carrier 4 is carried out from within the preliminary roving winding rail 2.

(Example 2) Next, a second example will be described according to FIGS. 6 to 9. In this embodiment, the 1lEi machine 11 always transports the carrier 4 to a predetermined position suitable for the roving tables in odd-numbered rows, and moves it to a position suitable for the roving tables in even-numbered rows using another feeding mechanism. This embodiment differs greatly from the previous embodiment in that In addition, as shown in FIGS. 9(a) and 9(b), one connection and disconnection device r1114 is provided at a predetermined position at the end of the carry-in side of the preliminary roving winding rail 2. Nearby feeder 33
is installed. As shown in FIGS. 6 and 7, a pair of brackets t and 34a are provided on the upper surface of the preliminary roving winding rail 2.

34b is fixed with a part thereof protruding to the side of the rail 2, and a support rod 35 is fixed parallel to the preliminary roving rail 2 between both brackets 34a and 34b.

A movable body 36 is supported on the support Orad 35 so as to be movable along the preliminary roving winding rail 2, and a bracket 34
It is fixed so as to be integrally movable via a bracket 38 with respect to a piston rod 37a of a cylinder 37 as a drive cylinder 37 fixed to a.

A support shaft 39 is fixed to the movable body 36 so as to extend in the vertical direction and partially protrude from the lower surface of the movable body 36 . An engagement lever 41 and a lever 42 are supported on the protruding end of the support shaft 39 via a rotating member 40 so as to be able to move in one direction. When the engagement lever 41 is installed at the same height as the engagement roller 6 of the conveyor 4 carried into the preliminary roving winding rail 2, it has a length such that its tip can intersect with the preliminary roving winding rail 2. is formed. A pin 43 is fixed between both levers 41 and 42, and the other end of a spring 45 is hooked to a hook pin 44 protruding from the lower surface of one end of the movable body 36.
3, and the engagement lever 41 is biased in a direction intersecting the preliminary roving winding rail 2 (clockwise in FIG. 6).

The lower surface of the movable body 36 is in contact with the lever 42 and the lever 42 is in contact with the lever 42.
and a stopper 46 that prevents the engagement lever 41 from being rotated excessively beyond the position perpendicular to the preliminary roving winding rail 2.
is installed protrudingly. On the other hand, in the preliminary roving winding rail 2, there is a long hole 47 in the upper part of the side wall on the side opposite to the engaging lever 41, which allows the engaging lever 41 to enter into the preliminary roving winding rail 2.
is formed along the support rod 35. Also, at the time when the screw-in rod 37a is retracted and the movable body 36 is placed in the standby position (the position indicated by 8 in FIG. 6), the J3
In front of the stopper 46 (to the left in FIG. 6) is a regulating roller 48 that engages with the engagement lever 41 to regulate its rotation.
is attached via a bracket 49.

Next, the operation of the apparatus configured as described above will be explained. In the feeding device 33, the movable body 36 is maintained at the standby position shown by A in FIG. 6, except when performing the roving change operation for even-numbered rows. In this state, the engagement lever 41 comes into contact with the regulation roller 48, resisting the biasing force of the spring 45, and retreats so that the leading end cannot engage with the engagement roller 6 of the conveying body 4 carried into the preliminary roving winding rail 2. held in position. In this state, the carrier 11 carries the carrier 4 into the preliminary roving rail 2 in the same manner as in the previous embodiment. The carrier 11 is always the carrier 4
The transport body 4 is carried into a predetermined position where the engagement roller 6 at the forefront can engage with the positioning lever 17 of the connection/disconnection device 14 . Next, as the carrier 11 moves forward, the carrier 4 and the connecting body 12 are cut 1311 in the same manner as described above, and at the same time, the carrier 4 is cut 1311 in a manner suitable for changing the odd-numbered rows of rovings as shown in FIG. 9(a). placed in position. Therefore, in the case of an odd-numbered phase system, the roving change operation is performed by the roving change machine in a state where the connection between the feeder 4 and the connection body 12 is disconnected by the connection switching device 14. In other words, in the case of changing the roving in an odd row, the feed is 5A and 3.
3 does not require any operation. After the roving change operation is completed, the transport body 4 is carried out in the same manner as in the previous embodiment.

On the other hand, when it is necessary to change the rovings of even rows, the carrier 4 is first carried into a predetermined position by the carrier 11 in the same manner as described above, and then the connection and disconnection device 14 is moved as the carrier 11 moves forward. As a result of the operation, the conveyor 4 is separated from the connecting body 12 and placed in a position suitable for changing the rovings in odd rows. In this state, the feeding device 33 starts operating. As the cylinder 37 is activated and the piston rod 37a protrudes, the movable body 36
moves forward from the standby position along the support rod 35 (sixth
(move to the left in the diagram). As the movable body 36 moves forward, the engagement lever 41 and the lever 42 are rotated about the support shaft 39 in the direction a shown in FIG. 6 by the elastic force of the spring 45.

Then, the tip of the engagement lever 41 entered the preliminary roving winding rail 2 through the elongated hole 47 and rotated to a position perpendicular to the preliminary roving winding rail 2.
comes into contact with the stopper 46 and its rotation is restricted, and the engagement lever 41 is held in a state perpendicular to the preliminary roving winding rail 2, that is, in a position where it can engage with the engagement roller 6, as shown by the solid line in FIG. be done. As the movable body 36 moves further forward, the conveying body 4 is integrally sent to the back side of the preliminary roving winding rail 2 together with the engagement lever 41 via the engagement roller 6. When the carrier 4 moves by one pitch, the cylinder 3
7 stops, and the conveyor 4 is moved from the position ♂t, which is suitable for changing rovings in odd-numbered rows, to the back side of the split-phase bobbin rail 2 by one pitch, which is suitable for changing rovings in even-numbered rows. placed in a suitable position. The rear end of the carrier 4 is in contact with the pressing member 30 of the pressing and urging device 28 disposed on the out-end side, but when the piston rod 37a protrudes, the air pressure in the air cylinder 29 is reduced. It has been adjusted and the piston rod 37
As the screw a protrudes, the screw i/n bolt 29a is smoothly pushed into the air cylinder 29. Na, r'3, feeding device 3
3 moves the conveyor 4 from the position shown in FIG. 9(a) to the back side of the preliminary roving winding rail 2, the positioning lever 17 is rotated and engaged as shown in FIG. 9(b). It is placed at a retracted position where it cannot engage with the matching roller 6. After the conveyor 4 is placed at a position suitable for changing the even-numbered rows of rovings, the roving changing machine performs the roving changing operation.

After completing the roving table work, the feed device 33 is activated based on the completion signal.
The cylinder 37 is actuated and its piston 37a is activated.
is pulled in, and the movable body 36 moves backward. Also, after the cylinder 37 is activated, the air cylinder 29 of the four-force pressing device 28 is activated.
The air+1 force is increased, the piston 0 end 29a protrudes, and the conveying body 4 is moved to the gear N7 lnd side l\wJ via the pressing member 30.

As the movable body 36 moves backward, the engagement lever 41 moves rightward from position 8 δ in FIG. 6 in a state perpendicular to the preliminary roving winding rail 2. After moving to the position where it engages with the regulation roller 48, the engagement lever 41 moves as the movable body 36 moves.
is rotated counterclockwise in FIG. 6 against the elastic horn of the spring 45, and when the movable body 36 is placed in the standby position v3, the engagement lever 41 is withdrawn from the preliminary roving winding rail 2. and is placed in a retracted position where it cannot engage with the engagement roller 6. After that, the original position where the carrier 4 was brought in by the carrier 4111,
In other words, it is placed at a suitable position on the odd-numbered rows of roving tables. From this position, the carrier 4 is moved by 1lfllllll.
will be carried out.

Note that the present invention is not limited to the above-mentioned embodiments, and for example, an engaging member as shown in FIG. 50 and a spring 51, or adopt a device with a different configuration as a connection/disconnection device, or set the loading position of the 1M1111 to a position suitable for changing even rows of roving, and use the feeding device flff33 to change the rovings of odd rows. The roving may be moved to a suitable position for changing the roving. Further, in the feeding device of the second embodiment, a combination port of a Tanabata and a ball screw may be used instead of the cylinder 37 as a means for reciprocating the movable body 36. In this case, if a motor whose rotation amount can be adjusted, such as a motor or a step motor, is used, the position at which the conveying body 4 and the connecting body 12 are separated by the connecting and disconnecting device is not necessarily an odd number column or an even number column. Even if it is not a suitable position for column fl eJ,
It becomes possible to accurately determine the arrangement of the carrier 4 based on the stop position of the moving body 36.

(Effects of the Invention) As described in detail above, according to the present invention, the roving table work of the preliminary roving winding carried into the preliminary roving winding rail and the roving winding suspended from the creel is carried out by the roving changing machine. When performing every other row, even when full bobbins doffed from the roving machine are transported to the preliminary roving winding rail 2 via the interlocking conveyor, the roving can be changed between odd and even rows without any problem, and even in the roving process. It becomes possible to carry out the ball 1!11 work without hindrance. Furthermore, in the invention as set forth in claim 2, since the position of the person carrying out the conveyor by the carrier is always constant, the control of the BVA machine becomes easy when the number of spinning machines is large. In addition, the loading and unloading of the conveyor and the feeding by the feeding device 33 are performed automatically, but if for some reason the position of the conveyor is mixed up, a By operating the feeding device 33, the arrangement position of the carrier 4 can be changed in a cylindrical manner.

Roving windings are suspended from the creel in two rows in the front and back, and the roving change operation with the preliminary roving windings carried into the preliminary roving winding rail extending in the front direction of the creel is carried out. In a spinning machine that uses a thread changing machine to wind every other row along the longitudinal direction of the spinning machine frame, a preliminary roving winding rail and a conveying path continuous to the rail are moved, and at a predetermined interval, the same number of rovings as one row of creel are wound. Place the carrier with the spare roving winding suspended therein into the spare roving winding rail so that its stopping position is shifted by one pitch of the roving winding row of the creel from the stopping position during the previous roving change operation. How to carry in the preliminary roving into the spinning machine. 2. A preliminary roving winding rail is provided above the front side of the creel that suspends the roving windings in two rows in the front and back, and the preliminary roving winding rails are transported to the rail by moving through the preliminary roving winding rail and a conveyance path that is continuous with the rail. The same number of spare roving windings as the number of roving windings for one row of creels are suspended from the body at predetermined intervals, and the conveying body is connected so as to be able to come and go. In a spinning machine that uses a thread changing machine to move every other row along the longitudinal direction of the spinning machine frame, a spinning machine is provided at a predetermined position on the conveyor carry-in side end of the preliminary roving winding rail so as to be movable along the rail. and a movable body that is reciprocated between an operating position and a standby position by a drive device, and the movable body has an engagement lever that engages with an engagement portion provided at a predetermined position of the conveyance body. A preliminary roving carrying device for a spinning machine, which is movably arranged in a retracted position when the movable body is placed in a standby position and in an engagement position capable of engaging with the engaging portion when the movable body moves forward.
