Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sliver splicing device in a roving frame.

[Conventional technology] In recent years, various types of automation have been carried out in spinning mills to save labor and improve productivity, and even in the roving process, pipe changes and bobbin conveyance have been automated, but sliver splicing work has not been carried out as before. It is done manually. Manual sliver joining work involves polymerizing the ends of two slivers and hand-rubbing the overlapping parts.The strength of the six overlapping parts is sufficient, and the joint part does not cause thick spots in the subsequent process. In order to do this, skill is required in the sliver splicing work. In order to solve this problem, Japanese Patent Laid-Open No. 62-97929 proposes a device that automatically performs the sliver splicing operation.

[Problems to be Solved by the Invention] The conventional sliver splicing device described above reliably performs the sliver splicing work, but in a rover frame, there are a number of sliver splicing work locations corresponding to the number of spindles, and a sliver splicing device is required for each location. Installing this will result in a significant increase in equipment costs. Since sliver splicing work is not performed frequently, an automatic machine that moves along a rail installed at a position corresponding to the position where sliver splicing work is required is equipped with a sliver splicing device.
It is conceivable to move an automatic machine to a position where the sliver splicing work is required and have it perform the sliver splicing work. However, if a movable continuous rail is provided at a position corresponding to the position where the automatic machine requires sliver splicing work, not only will the equipment cost be high, but the distance the automatic machine must travel will be longer. There is also the problem of 6. The present invention has been made in view of the above problems, and
The object of the present invention is to provide a sliver splicing device for a roving frame, which saves labor by performing the sliver splicing work using an automatic machine, and can reduce the number of running rails installed in the automatic machine.

[Means for Solving the Problems] In the present invention, a crane is provided above a plurality of roving frames arranged in parallel in a direction perpendicular to the longitudinal direction of the spinning machines, and the crane A running rail having at least a portion extending parallel to the longitudinal direction of the roving machine is fixed thereto, and an automatic sliver splicing machine that performs sliver splicing work on the sliver of a can placed at the rear of the roving machine is attached to the running rail. Equipped to run along the

1 Effect] With the above configuration, in the apparatus of the present invention, when sliver splicing is required, the crane is orthogonal to the longitudinal direction of the roving frame so that the running rail is in a state corresponding to the position where sliver splicing is required. direction and stop at the relevant position. Next, an automatic sliver splicing machine equipped on the traveling rail moves to a position where work is required, and performs the sliver splicing work at that position. Since the crane moves in a direction perpendicular to the longitudinal direction of the roving frame frame, the running rail can be positioned without unnecessary movement in a position corresponding to the point where the sliver splicing operation is required.

[Example 1] A first example embodying the present invention will be described below with reference to FIGS. 1 to 13.

As shown in FIG. 1, a plurality of roving frames 1 are arranged in parallel, and behind the roving frames 1, multiple rows of cans 8 for supplying sliver S to the roving frames are arranged in parallel.

Above the roving frame group 2, there is a pair of crane rails 15 that are perpendicular to the longitudinal direction of the roving frame 1 and one end of which is connected to the roving frame group 2.
It is constructed so that it extends from above to the outside. A talen 16 is suspended on the crane rail 15 via a driving roller 7a and a driven roller 17b, and is moved in a direction perpendicular to the longitudinal direction of the roving frame 1 by the forward and reverse rotation of the motor 8.

A traveling rail 19 having a length approximately equal to the entire length of the roving frame 1 is provided on the lower surface of the crane 16.

The running rail 19 is equipped with an automatic sliver splicing machine 22 which performs sliver splicing work on the sliver S of the can 8 so as to be movable. The sliver splicing machine 22 is the fourth to
As shown in FIG. 6, a box-shaped housing 23 is supported in a suspended state via a bearing 28 and a bracket 29 about a rotating shaft 26° 27 to which a pair of driving rollers 24 and a driven roller 25 are respectively fixed. . Bracket 2
9 is fixed to both sides thereof via support pieces 29a or bear links 29b that engage with the end face of one running rail to position the sliver splicing machine 22 in the lateral direction (only one side is shown). A motor 30 is fixed to the negative side of the housing 23, and a gear 32 that meshes with a gear 31 fitted to the rotating shaft 26 is fitted and fixed to its drive shaft 30a. The splicing machine 22 moves along the traveling rail 19. A positioning plate 33 is fixed to the outer lower part of the running rail 19, and engagement grooves 33a are formed on the lower surface thereof at predetermined intervals (!the pitch of the bobbin wheel of an FJI spinning machine) on six sides, and on the upper surface of the housing 23. A substantially U-shaped support bracket 34 is fixed at a position corresponding to the outside of the positioning plate 33. An engagement lever 35 or one end thereof is rotatably supported by the support bracket 34 in a state perpendicular to the positioning plate 33, and is connected to a plunger of a solenoid 37 via a link 36.

The engagement lever 35 is urged to rotate in the direction of engagement with the engagement groove 33a by a screw spring (not shown), and is brought into engagement with the engagement groove 33a by the action of the solenoid 37. It is arranged so that it can be rotated to an impossible position. Further, a proximity switch 39 is attached to the support bracket 34 for detecting a detection target plate 38 fixed to the positioning plate 33 at a predetermined interval in correspondence with each engagement groove 33a.

Inside the housing 23, a screw shaft 40 constituting the side of the ball screw m is rotatably supported in a direction perpendicular to the running rail 19, and a guide rod 41 (sixth
(shown in the figure) is fixed. A gear 44 that meshes with a gear 43 fitted to the drive shaft of the motor 42 is fitted to one end of the screw shaft 40 so as to be rotatable together. Also, the screw shaft 40
A movable bracket 46 having a pole nut 45 is supported on the guide rod 41 so as to be movable as the screw shaft 40 rotates. An arm 47 that extends and contracts in the vertical direction is fixed to the movable bracket 46 and is extended and contracted by hydraulic or pneumatic pressure. A sliver S is attached to the tip of the arm 47.
A sliver gripping device 48 is installed for gripping the sliver. The sliver gripping device 48 is composed of a fixed gripping piece 49 in the form of a fork, and a movable gripping piece 51 that is rotated by a rotary solenoid 50 attached to the base end of the fixed gripping piece 49 .

On the lower surface of the housing 23 is a picing unit 5 having a configuration similar to that of the device disclosed in Japanese Patent Application Laid-Open No. 62-97929.
2 is fixed. The piecing unit 52 is fixed such that its sliver introducing portion 52a faces the lateral movement path of the arm 47. A sliver taking-in arm 5 is provided at the lower left and right sides of the piecing unit 52.
3 and the sliver holding arm 54 or a drive device (not shown), the sliver is moved from the same position as the retracted position shown in FIG.
The clock is equipped with a 70-degree hour hand that can be rotated to an operating position. The sliver intake arm 53 is the 7.1st
As shown in Fig. 1, the sliver splicing 11!122 is placed on the roving frame 1 side (left side in Fig. 5) when the sliver splicing work is performed, and as shown in Fig. 8 <b>. The sliver holding arm 54 corresponds to the sliver introduction part 52a of the piecing unit 52 by the sliver taking-in arm 53. Sliver S moved to position
It is formed to a length that allows it to be suppressed and held. The housing 23 is equipped with a control box 55 that transmits and receives signals to and from a control device (not shown) and controls the motor 30, solenoid 37, motor 42, rotarynoid 50, and the like.

Next, the operation of the apparatus configured as described above will be explained. The crane 16 is on standby at the end of the roving a1 group, and the roving machines 1 are operated so that their full pipe times, ie, pipe change times, do not overlap.

Now, in this state, when the roving frame 1 approaches a full roving frame, a full roving frame warning signal is output from the roving frame 1 to the control device, and the control device recognizes the next roving ai that requires work, and sends the crane 16 to the concerned roving frame ai. A command signal for moving the spinning machine 1 to a corresponding working position is output. As a result, the crane 16 moves to a position corresponding to the row of cans that requires sliver splicing work and stops at the same position, and then the machine is stopped before the 1 ml roving becomes full. After the frame of the roving frame 1 is stopped, a movement command signal is output to the sliver splicer 822, the motor 30 is driven to rotate normally, and the sliver splice 1122 starts moving along the traveling rail 19. The stop position of the sliver splicing machine 22 is indicated by the number of detection plates 38 detected by the proximity switch 39, and the control box 55 issues a stop command to the motor 30 when the proximity switch 39 detects a predetermined number of liquid detection plates 38. At the same time, the solenoid 37 is energized. As a result, the motor 30 is stopped, and the sliver splicing machine 22 continues to move slowly along the traveling rail 19 by inertia.

On the other hand, the engagement lever 35 is rotated to the engagement position by the excitation of the solenoid 37, but comes into contact with the lower surface of the positioning plate 33 and its rotation is restricted, and the sliver joint 8122
As the engagement lever 35 moves, the positioning plate 3
It moves while touching the bottom surface of 3. When the sliver splicing machine 0-22 moves to a position where the engaging lever 35 corresponds to the engaging groove 33a, the engaging lever 35 or the engaging lever 33a engages to prevent the movement of the sliver splicing 1!22, and the sliver The splicing machine 22 stops at a predetermined position where a sliver splicing operation is required. Then, the sliver splicing operation is started at this position.

As shown in FIG. 7<a>, the can 8 is in a state where the used can and the spare can correspond to the lower part of the roller 56 that guides the sliver S to the draft part (not shown) of the roving frame 1. They are arranged in two rows along the longitudinal direction of the spinning machine 1. The sliver S housed in the full can is arranged such that its end extends along the longitudinal direction of the roving frame 1 at the center of the can 8, as shown in FIG.

As shown in FIG. 7(a), the sliver S from the can 8F in the front row to the roving frame 1 via the roller 56 extends in the vicinity of the lower part of the piecing unit 52 in parallel to the sliver introducing portion 52a. In this state, first, the arm 47 is slightly extended, and the fixed gripping piece 49 of the sliver gripping device W and 48 are
A sliver S is introduced in between. Next, the rotary linenoid 50 is actuated 1, and the movable gripping piece 51 is rotated to the gripping position as shown in FIG. Ru. Next, the arm 47 is retracted to its original position, and the sliver S is moved to the vicinity of the sliver introduction part 52a of the piecing unit 52. In this state, the sliver take-in arm 53 and the sliver holding arm 5

2a and held by both arms 53 and 54, resulting in the state shown in FIG. 7(b). Next, the motor 42 is driven to rotate normally, and the am 47 is moved to the sliver gripping device 4.
Piecing unit 5 while gripping sliver S
Start moving in the direction away from 2. At this time, the sliver S is transferred to the sliver introduction section 5 of the piecing unit 52 by the sliver take-in arm 53 and the sliver presser arm 54.
2a, the sliver S is cut as the arm 47 moves, resulting in the state shown in FIG. 7(C). After cutting the sliver S, the rotary renoid 50 is activated and the movable gripping piece 51 is moved to the release position as shown in FIG. 8(d), and the sliver gripping device 48 is released from gripping the sliver S. Or it will fall into the 8th floor of Kenshu. The arm 47 is moved to a position substantially corresponding to the end of the central sliver S of the can 8B, and at that point the normal rotation of the motor 42 is stopped.

Next, the arm 47 is extended and the sliver gripping device 48 is lowered to a position where it can engage with the sliver S end of the can 8B as shown in FIG. The end of S is fixed gripping piece 4
In this state, the rotary solenoid 50 is activated and the sliver S is held by the movable gripping piece 51 and the fixed gripping piece 49. Then, the arm 47 is retracted and the sliver S is pulled out from the can 8B, and the sliver S is pulled out from the can 8B.
It will be pulled up above. After the sliver gripping device 48 has risen to a predetermined position, the motor 42 is driven in reverse, and the arm 47 is moved together with the moving bracket 46 from the piecing unit 52 to the roving frame 1 side, as shown in FIG. 7(e). Sliver gripping device 48
The end of the sliver S gripped by the picing unit 52
The sliver is transported to a position corresponding to the sliver introducing portion 52a. Prior to the movement of the arm 47, the sliver taking-in arm 53 has been moved from the position shown in FIG. 8(d) to the retracted position shown in FIG. 8(e). As shown in FIG. 7(e), with the end of the sliver S connected to the full can 8B located at a position corresponding to the sliver introduction part 52a, the sliver intake arm 53 is placed at the position shown in FIG. 8(e). Then, the sliver S is rotated counterclockwise again to the state shown in FIG. 8(f), and the sliver S held by the sliver gripping device 48 is introduced into the sliver introducing portion 52a. Next, the motor 42 is reversely rotated to move the arm 47 in a direction away from the picing unit 52 as shown in FIG. 7(f), and the end of the sliver gripped by the sliver gripping device 48 is cut. Then, in this state, the piecing unit 52 starts operating and performs the joining operation 4 of the sliver S. On the other hand, the arm 47 is moved in the direction away from the rough spinning Ill by the forward rotation of the motor 42 and moved to a position corresponding to the empty can 8F, after which the rotary solenoid 50 is activated and the movable gripping piece 51 is placed in the release position. The S end of the cut sliver falls into the can 8F. After dropping the sliver end into can 8F, arm 4

) from the position shown in Figure 8(a).
After returning to the position shown in >, the sliver S after completion of joining is placed at the spinning position where it passes through the rollers 56 and reaches the roving tIA1 as shown in FIG. 7(h), thus completing the sliver splicing operation. After the sliver S is released from the piecing unit 52, the solenoid 37 is de-energized, the engagement lever 35 is placed in the retracted position away from the engagement groove 33a, and the motor 30 is driven to operate the sliver splicing machine 22. The machine moves to the next working position, and the sliver joining work is performed in the same manner as above.

When the sliver splicing work of all the weights that require sliver splicing work is completed, the sliver splicing machine 22 moves to the standby position. Next, the roving I11 is started and winding starts.
After the pipes are full, the machine is stopped. And full bobbin F
The bobbin is doffed from the roving frame 1, and instead, a tube change operation is performed in which the empty bobbin E is inserted into the bobbin wheel from which the full bobbin F was taken out.

Further, after the tube change operation is completed, the roving ra1 is restarted and starts winding the roving yarn.

As mentioned above, if the machine is stopped a little before the roving machine 1 stops full, and the sliver splicing work is performed, then the roving machine 11 is operated again until the roving is full, and then the pipe change work is performed. In this case, the overlapping portion caused by the sliver splicing is wound up by the first layer or the second layer of the bobbin where winding of the roving starts anew after the pipe change. Generally, the roving wound on the first or second layer of the roving bobbin is not used in the spinning machine and remains as residual roving, so the overlapped portion created by the sliver splicing process is used as spun yarn. 6 The quality of spun yarn in the first process improves. If this spliced joint portion may be used as spun yarn in the spinning process, the roving frame 1 may be stopped for the sliver splicing work at the same time as the full pipe is stopped, or at the same time as the pipe changing work. The order of the sliver splicing work is not particularly limited.

The above sliver splicing work is performed using can 8 in the front row (roving machine side).
Although we have explained the operation when F becomes empty, the case where can 8B in the back row becomes empty is shown in Fig. 11(a).
As shown in (h), the arm 47 moves slightly in the lateral direction, but the movements of the sliver gripping device 48, sliver take-in arm 53, and sliver holding arm 54 are the same as in the seventh stage.
It is the same as that shown in Figures (a) to (h) and Figures 8 (a) to (f). That is, as shown in FIG. 11(a), after the crane 16 stops at a position corresponding to the row of cans that requires sliver splicing work, the sliver S
is introduced into the sliver introduction part 52a of the piecing unit 52, and then, as shown in FIG. 11(b), the arm 4
The sliver S is cut by moving 7, and the grip on the sliver S is released at the position where the cut end of the sliver S is conveyed to a position corresponding to the empty can 8B as shown in FIG. 11(C). do. Next, Figure 11 (
As shown in (d), the end of the sliver S is pulled out from the can 8F in the front row, and as shown in FIG. The sliver S is introduced into the sliver introducing section 52a. Thereafter, the sliver gripping device 48 cuts the sliver S at its end side, and the cut end is placed in an empty can 8B as shown in FIG.
The sliver gripping device 48 is released at the same position, and after releasing the grip on the sliver S, the sliver S returns to the original standby position as shown in FIG. 11(h).

In the roving frame, the pitch of the bobbin wheels is smaller than the diameter of the cans, so the cans 8 are arranged in multiple rows at the rear of the roving frame 1. The number of rows of cans 8 used at one time on Rover 1 is 4.
In the case of rows, as shown in Fig. 12, the 8 sliver capacity of each row at the start of operation of the machine is adjusted to the doffing cycle, and the sliver capacity is 1/4.2/4.3 in order from the first row. /4.If set as 4/4, the sliver replacement period when can 8 becomes empty will be 2 in order starting from the first column.
Since the rows are visited in order from the third row to the fourth row, the sliver splicing work can be performed in sequence in conjunction with the pipe changing work, and the stopping time of the roving frame 1 is shortened. Moreover, it becomes easy to set the stopping position of the crane 16.

Furthermore, in this embodiment, as shown in FIG. 13, the rows of cans 8 are arranged so that the positions of the cans correspond to the pitch P of the bobbin wheel for 1 ml of roving, so that the sliver splicing machine 22 When the running rail 19'2 is moved and stopped at a predetermined work position in order to perform sliver splicing work, the stop position can be easily controlled. That is, when performing sliver splicing work on cans in the first row, for example, the sliver splicing machine 22 moves from the left side to the right side in FIG.
If you create a program that will first stop at the position where two detection plates 38 are detected, and then complete the sliver splicing work at that position, from then on, the program will stop every four detection plates 38 detected. .

#122 are sequentially stopped at predetermined positions. Similarly, when performing sliver splicing work on the second row, the proximity switch 39 sets a 10-g sensor that stops every time the detected plate 38 is counted four times from the beginning, and when performing sliver splicing work on the third row, The first stop is at the position where one detected plate 38 is detected, and from then on, a program is created to stop every four detected plates, and in the case of the fourth row sliver splicing work, the first detected plate 38 is stopped. The stop position of the sliver splicing machine 22 can be easily controlled by creating a program that stops the sliver splicer 38 at the position where three sliver splices are detected, and then stops every four sliver splices from then on.

[Example 2] Next, a second example will be described according to FIGS. 1.4 and 1.5. In the apparatus of this embodiment, after the crane 16 has stopped corresponding to the spinning frame 1, the sliver splicing machine 22 can be moved to a position corresponding to the sliver splicing work position of each can row. The apparatus differs from the apparatus of the previous embodiment in that running rails 19 are provided, each of which connects the ends of rails extending parallel to the longitudinal direction of the roving frame 1. Therefore, in the apparatus of this embodiment, the stopping position of each crane 16 is limited to a predetermined position corresponding to the roving frame 1, and at that position, the sliver splicing machine 22 runs toward the position where sliver splicing work is required. move on the sill 19.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and in addition to one rail for running a sliver splicing machine, a bobbin transport body having a bobbin hanger for one roving frame suspended from the crane 16 can run. A conveyor running rail may be provided that extends parallel to the longitudinal direction of the roving frame. In this case, when the bobbin bunker of the bobbin conveyor carried into the conveyor running rail is located above the spindle of the roving frame, the full bobbin doffed by the roving frame can be suspended. Then, with the full bobbin suspended, the crane 16 is moved to the unloading position of the bobbin conveyor, and at the unloading position, the conveyor running rail connects with the roving winding rail 1 of the spinning machine group, and the The bobbin conveyor inside the rail is carried out and conveyed to the roving rail of the spinning machine group.

``Effects of the Invention'' As detailed above, according to the present invention, the sliver splicing work, which was conventionally done manually, is automatically performed by the sliver splicing machine, and the sliver splicing machine roughly moves the upper part of the roving frame group. Since the sliver splicing machine is moved to the working position together with a running rail installed on a crane that moves in a direction perpendicular to the longitudinal direction of the spinning machine, the number of running rails for the sliver splicing machine is reduced, resulting in lower equipment costs.
