BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a full wrap formed by a lap forming machine as a pre-process, is hung and conveyed, and is supplied onto a lap roller of a lap feeding section of a post-process machine. In order to smoothly perform lap splicing in the lap transport splicing system that peels off the end and automatically or manually wraps it to the preceding lap of the post-process machine,
The present invention relates to a technique for controlling the position of the lap end of a full lap.

[0002]

2. Description of the Related Art As a conventional lap transport joint system,
There is a Japanese Patent Publication No. 5-36330. According to this
A movable frame that runs between the lap former of the pre-process machine and the comber as the post-process machine rotates the center hole of the lap bobbin with a full lap suspension mechanism that has hooks that sandwich the center hole of the lap bobbin from both sides in the axial direction. Small ball wrap hanging mechanisms that freely support and rotate the small ball wraps are provided so that they can be raised and lowered, respectively. When the comb moves up, the lap sheet is consumed on the feeding part of the comb as it is combed and becomes a small ball wrap, and when the comber stops, the small ball wrap is suspended from both sides of the center hole of the lap bobbin by the small ball wrap suspension mechanism. Supply wrap (hereinafter, old lap) that is connected from this small ball wrap to the combing unit by lifting it from the Cutting is performed upstream of the feed roller, and then the full wrap suspension mechanism is lowered to place the full wrap on the lap roller in the wrap feeding section of the comber, and then the lap end of this full lap is stripped by the air from the air nozzle. Then, hang it down along the fleece guide of the lap feeding section, and then when you activate the comber, the feed roller in front of the fleece guide will overlap the lap end of the full lap with the old lap to perform lap joining. ing. And, conventionally, the lap end of the full wrap is easily peeled off by the air from the air nozzle,
Moreover, the lap former side has aligned the full wrap position at the stripping position so that when it is peeled off and hangs down, the trailing end of the preceding old wrap is lap-joined favorably and the lap margin is provided.

[0003]

By the way, as shown in FIG. 9, the peeling position B of the wrap end suitable for the lap joint is a horizontal center line CL passing through the center of the full wrap 100.
It will be considerably lower. In the above-mentioned conventional technique, the lap end is positioned at such a lap end stripping position B (FIG. 9) by the lap former, and the full lap suspending mechanism suspends the full lap in the state (FIG. 9). of),
Since it is conveyed above the comber (in FIG. 9), the lap end at the stripping position B hangs down as shown in FIG. 9 due to the airflow acting on the lap end during conveyance, vibration during conveyance, etc. When placed on the roller 41 (see FIG. 9).
In addition, the hanging lap portion La was caught between the lap roller 41 and the lap roller 41, and even if it was blown with air, it could not be peeled off and automatic lap joining could not be performed. Also, only full wrapping is patented 1688
Even if it is done automatically like No. 739, and when the lap joint is dependent on human hands, when the lap portion of the full wrap is sandwiched between the lap roller and the lap roller, the heavy full wrap is lifted and the lap end is taken out to wrap. There was a problem of heavy labor that had to be passed on. Such a problem occurs not only between the lap former and the comber, but also between the sliver lap machine as a pre-process and the ribbon wrap machine that performs lap joining as a post-process.

[0004]

SUMMARY OF THE INVENTION The present invention is a lap transport splicing system for suspending and transporting a full lap from a preceding process machine onto a lap roller of a spinning machine for lap splicing. The purpose is to prevent the wrap end from hanging down during suspended transportation, and to control the position of the lap end so that the lap joint can be performed smoothly.
Before hanging the full wrap, wrap the full wrap end,
The peeling prevention position is set so that the lap end does not peel off during suspended conveyance, and the lap end of the full lap supplied onto the lap roller in this state is reversed independently of the lap roller to a suitable peeling position for lap joining. It is characterized by being located at.

[0005]

According to the above, the wrap end of the full wrap formed by the previous process machine is positioned at the peeling prevention position on the outer periphery of the wrapping machine, and in this state, it is hung and conveyed using the center hole. , The end of the wrap does not peel off during hanging transportation. Therefore, when the full bobbin is supplied and placed on the lap roller of the post-process machine, the lap end does not get caught between the lap roller and the lap roller. Then, the full lap placed is reversed by the reverse rotation of the lap roller to move the lap end from the peeling prevention position to the peeling position suitable for lap joining, so that the lap joining (automatic or manual) thereafter is performed. Will be smooth. It is preferable that the peeling prevention position is set above the horizontal line below the horizontal center line passing through the center of the lap bobbin of the full wrap in the horizontal state. It is more preferable to set the position beyond the vertical center line passing through the center of the full wrap to be conveyed.

Above the calendar roller 6, a swing lever 15 a for discharging the full wrap 100 onto the lap conveyer 3 is supported by a discharge cylinder 15 so as to swing.

The control device 20 for controlling the lap winding device 2 judges that the full lap has been reached by the length measurement signal from the winding length measuring device 21 for the lap sheet U, which is connected to the winding drum 5. Then, the stop command is output to the main motor 10. Then, after the winding drum 6 is stopped, a command to rotate only the auxiliary motor 11 is output for the time set in the timer 22 in the control device 20. afterwards,
The pressure of the pressure cylinder 14 is released, and the lap plate 1
It is programmed in advance so that the holding of the lap bobbin 13 by 2 is released, a command for rocking the rocking lever 15a is output, and the full bobbin 100 is discharged onto the lap transport conveyor 3.

During the time set in the timer 22, only the auxiliary motor 11 is rotated to rotate only the take-up drum 5 in the take-up direction, and the lap sheet U is moved between the take-up drum 5 and the calendar roller 6. After cutting, the bobbin 100 is rotated by the rocking lever 1 so that the cutting end (lap end) is continuously rotated.
In a state of being kicked by 5a, rolling on the guide plate 16 and discharged onto the lap transfer conveyor 3,
The time is set to rotate to the wrap outer peripheral position C which is the peeling prevention position A. This peeling prevention position A is used when the lap transport joint device 30 described later sandwiches the center hole 13A of the lap bobbin 13 from both sides and transports the lap bobbin 13 in a suspended state with the shaft center horizontal.
Is a position that does not easily fall off, and is at least a position above the wrap stripping position B when joining the wraps in the circumferential direction, preferably above the horizontal center line CL, in the comber 4. In addition, as shown in FIG.
When the position exceeding the vertical center line CV is set as the peeling prevention position A, the peeling prevention becomes more effective. In the present application, the timer 22 of the control device 20 and the winding drum 5 that is independently rotated constitute a lap end preliminary positioning device 25 that positions the lap end of the full wrap 100 at the peeling prevention position A on the outer circumference of the lap. . Preliminary positioning device for lap end 2
As described above, 5 uses the lap cutting rotation of the take-up drum 5 as described above, but the lap take-up device 2 does not perform such position control and separates the lap take-up device 2 in front of the lap take-up device 2. A pre-positioning device for the full lap 100 is provided in the pre-positioning device, and a pair of rollers for mounting and rotating the lap and a lap end detector are provided at a predetermined position facing the outer circumference of the full lap. The lap end may be positioned at the peeling prevention position A by the lap end detector while rotating the full lap by the roller.

Next, the full wrap 100 is conveyed to the comber 4,
The lap conveying and splicing device 30 for splicing the laps will be described, but since this device is that of Japanese Patent Publication No. 5-36330, it will be briefly described. As shown in FIGS. 3, 6, and 7,
The movable frame 31 that travels above the lap conveyor 3 and above the comb 4 has a pair of openable and closable hooks 32 that sandwich the center hole 13A of the lap bobbin 13 from both sides in the axial direction. Full wrap suspension mechanism 33, a pair of openable and closable support arms 35 having rotating rollers 34 that rotatably support the center hole 13A of the lap bobbin 13 from both axial sides, and a small ball rotatably supported by the support arm 35. Small bead wrap suspending mechanisms 38 each having a number of small bead wrap discharge units 37 each composed of a rotating roller 36 that is pressed against the outer periphery of the wrap 101 and is positively rotated by a motor are provided so as to be vertically movable. The small lap discharge unit 37 is provided with an air nozzle 39 for peeling off the lap end of the full wrap 100 placed on the lap roller 41 of the comb 4.

The comber 4 includes a plurality of combing units 4
A pair of front and rear wrap rollers 41 corresponding to each combing unit 4A are rotatably supported by the frame. The front and rear wrap rollers 41 are
It is continuous in the longitudinal direction, and each wrap roller 41 is shown in FIG.
As shown in FIG. 3, the detaching roller and the like of the combing unit 4A are transferred to the main motor 45 via the wrap roller drive system (lap roller reverse rotation drive device) 43 including the differential gear mechanism 42 and the combing unit drive system 44, respectively. It is connected. The auxiliary input shaft of the differential gear mechanism 42 is connected to a reverse rotation motor 46, and the main motor 45
When the reverse rotation motor 46 is driven in a state in which the driving of No. 1 is stopped, only the lap roller 41 is rotationally driven in the wrap winding direction. The reverse rotation motor 46 is not driven during normal combing, and normally the combing unit 4A
The lap roller 41 and the lap roller 41 are rotatably driven at a predetermined number of rotations by the power of the main motor 45.
The combing unit 4 rotates in the wrap feeding direction.
A wrap sheet U is supplied to A. 47
Is a fleece guide.

The controller 50 of the comber 4 controls the reverse rotation motor 46 in addition to various controls during normal combing. That is, when a signal indicating that the full wrap 100 has been placed on the lap roller 41 is transmitted from the control device 60 of the lap transport joint device 30, the reverse rotation motor 46 is activated by the control device 5.
A command to rotate is issued for the time set in the timer 51 inside 0. The time set in the timer 51 is the rotation time required to position the lap end of the full wrap 100, which was in the peeling prevention position A, in the peeling position B where the air nozzle 39 peels it off.

Wrap winding device 2 of ribbon wrap machine 1
When the lap winding is performed and the full lap 100 is reached, the controller 20 issues a stop command to the main motor 10,
The winding drum 5 stops. Next, the auxiliary motor 11 is rotated for the time set by the timer 22, whereby only the winding drum 5 is rotated in the winding direction while the calendar roller 6 is stopped, and the lap sheet U is transferred to the calendar roller 6.
And the take-up drum 5 is cut, and the cut end is continuously rotated to be positioned at the wrap outer peripheral position C. Next, the pressurization of the pressurizing cylinder 14 is released, the holding of the lap bobbin 13 by the lap plate 12 is released, and the swing lever 15a kicks out the full wrap 100 on the winding drum 5. The full wrap 100 rolls on the guide plate 16, contacts the stopper 17, and is placed on the lap transport conveyor 3. At this time, the end of the wrap which was at the wrap outer peripheral position C is located at the peeling prevention position A.

Whenever one full wrap 100 is discharged, the lap transport conveyor 3 is intermittently transferred by the interval L of the combing unit 4A, and six full wraps 100 are placed on the conveyor 3 at the interval L. While maintaining this state, the conveyor 3 is continuously driven to position the six full wraps 100 at the full lap preparation position directly behind the combing unit 4A. At this time, needless to say, the wrap end of each full wrap 100 is the peeling prevention position A. Then, the full-wrap suspending mechanism 33 of the full-lap transport joint device 30 descends, and the hooks 32 grasp and lift the center holes 13A of the lap bobbins 13 of the six full-laps 100. Then, in the suspended state, the comb 4 is moved upward (FIG. 3). At this time, the wrap end tries to be peeled off due to the vibration caused by the conveyance or the air flow acting on the lap end along with the movement, but the lap end is at the peeling prevention position A, so that it is prevented from peeling off and hanging down. It

Above the comber 4, the small ball wrap suspending mechanism 38 first descends to support the small ball wraps 101 on the lap rollers 41 of the comber 4 in the stopped state, respectively.
The rotating roller 36 is rotatably clamped and lifted, and the rotating roller 36 is pressed against the outer circumference of the small ball wrap 101 (FIG. 4). Then, the movable body 31 is slightly moved forward, the small ball wrap suspension mechanism 38 is lowered, and at that position, the rotary roller 36 is driven to connect to the combing unit 4A. (Old wrap) L2 is wound and cut. Then, the full wrap 100 is supplied onto the wrap roller 41, and the full wrap 10 is fed from the hook 32.
0 is released. In this way, when the full wrap 100 is placed on the lap roller 41, the lap end does not hang down during the air conveyance, so the lap end is not caught between the lap roller 41 and the lap roller 41. When the control device 60 of the lap conveyance joint device 30 notifies the control device 50 of this opening completion, the control device 50 outputs a rotation command to the reverse rotation motor 46 for the time set in the timer 51. Reverse motor 46
Rotation of the lap roller 41 via the differential gear mechanism 42.
And the full wrap 100 is rotated in the winding direction so that the wrap end that was at the peeling prevention position A is located at the peeling position B.

When the lap end is positioned at the stripping position B in this manner, air is ejected from the air nozzle 39 toward the lap end. Since the lap end is at the peeling position B, it is easily peeled off from the outer circumference of the lap and the fleece guide 4
7 It hangs along the top. Then, when the machine base is driven and the lap roller 41 is rotated in the feeding direction, the new lap L1 is fed toward the feed roller and overlapped with the cut end of the preceding old lap L2, and the lap joining is completed. . In this embodiment, the lap joining is automatically performed. However, the present invention can be applied to the case where the lap transport is automatically performed and the lap joining is manually performed. In addition, when the full wrap is rotated by the winding drum of the wrap winding device and the cut wrap end is positioned at the wrap outer peripheral position C which becomes the peeling prevention position A subsequently after cutting, in the present application, Rotation was performed while the full wrap was being pressed against the winding drum by the pressure cylinder, but as the applicant of the present application previously filed as Japanese Patent Application No. 4-353256, the winding drum was stopped after the pipe was fully stopped. Drive the cutting machine to cut the lap sheet between the calendar roller and the take-up drum, stop the take-up drum at this cutting timing, and then apply the pressure of the lap bobbin to the take-up drum at the time of taking up the wrap sheet. If the pressure is made smaller than the pressure, the winding drum is rotated, and the cut end of the lap sheet is positioned at the wrap outer peripheral position C, which is the peeling release position B after being kicked out. Deformation becomes small lap, improved accuracy of the rotational positioning.

[0017]

As described above, according to the present invention, the wrap end of the full wrap formed by the pre-process machine is positioned at the peeling prevention position on the outer periphery thereof, and in this state, the center hole is utilized. Since it is suspended and conveyed, it is possible to prevent the wrap end from peeling off and hanging down during suspended conveyance. Therefore, when the full wrap is placed on the lap roller of the post-process machine,
It is possible to prevent the lap end from being caught between the lap roller and the lap roller. Then, the full lap placed is reversed by the reverse rotation of the lap roller to move the lap end from the peeling prevention position to the peeling position suitable for lap joining, so that the lap joining (automatic or manual) thereafter is performed. Can be performed reliably and smoothly.
