Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present application relates to a roving end processing device for a roving bobbin doffed from a roving machine, and is capable of processing the roving end hanging from the roving bobbin for automated work. This is to facilitate the process.

Conventional technology and its problems Currently, there is a process of doffing the roving bobbin from the roving machine, transporting the doffed roving bobbin to the spinning machine, and hanging the transported roving bobbin from the creel of the spinning machine. The replacement work of replacing empty bobbins is completely automated. The cut end of the automatically doffed roving in the above process is only lightly attached to the outer circumferential surface of the roving bobbin due to fluff, and its holding power is weak. - Once sagging occurs, the weight of the dangling roving, vibrations, etc. will cause the roving to unravel, causing the roving end to tear and stick to surrounding equipment or be scattered. This has caused various problems.

For the purpose of preventing the above-mentioned roving ends from unraveling, the present applicant has previously published Japanese Patent Application Laid-open Nos. 62-282029 and 63-612.
As No. 2, we are proposing a device to prevent unraveling of the roving ends. These two conventional devices, while conveying the doffed roving bobbin, press the outer peripheral surface of the roving bobbin with a presser device and rotate the roving bobbin in the roving winding direction.
This device is designed to hold down the cut end of the roving that is attached to the outer circumferential surface, and has some effect as a device to prevent the cut end from unraveling, but the cut end is already unwound and hanging down. In some cases, the roving bobbin is simply pressed against the outer circumferential surface of the roving bobbin while it is hanging down, which not only causes inconvenience when connecting the thread when replacing the thread, but also causes the roving bobbin to have a wide contact area. Since it rotates in contact with the pressing device, it also has the disadvantage of roughening the surface of the roving.

Means for Solving the Problems In order to improve the drawbacks of the above-mentioned conventional apparatus, the present invention aims to improve the above-mentioned drawbacks of the conventional apparatus. In addition to providing a rotation mechanism that rotates the bobbin in the winding direction of the roving, a comb tooth-shaped scooping piece that scoops up the roving end hanging from the roving bobbin by rotation of the roving bobbin, and A processing head is provided which has a guide path for guiding the roving end to the outer peripheral surface of the roving bobbin without pulling it up, and a stroking surface for stroking the guided roving end. , to effectively and appropriately dispose of hanging roving ends.

The lifting device 6 in the conveyance path 5 configured as described above, specifically the lifter 13, is equipped with the roving end processing device 100 of the embodiment of the present application.
is attached, and the roving end processing device 100 has a lifter 13
A rotating mechanism 101 rotates the roving bobbin 9 transferred to the bed 24 in the winding direction of yarn 11, and a roving end 102 that comes into contact with the rotating roving bobbin 9 (Fig. 6.7) a processing head 103 that performs processing;
03 to a working position where it contacts the roving bobbin 9 and a non-working position where it separates from the roving bobbin 9.

First of all, the rotation mechanism 101 is configured as follows. On one side of the lifter 13 (the pedestal 106 fixed to the right side plate 105 in FIG. 1), a fitting protrusion 109° 109A is provided on both the front and rear ends of which a biasing member 108 and a workpiece 08A, which will be described later, are rotatably fitted. A bearing member 107 having a bevel gear 1 is attached to the front end of the bearing member 107.
10 is rotatably supported by an output shaft 111 having a gear 123 attached to its rear end. Therefore, this bevel gear 110 is
It meshes with a bevel gear 112 attached to the front plate 22, and a V pulley 113 is attached to the bevel gear 11.2.
are attached coaxially, and a V-belt 114 is wound between this V-pulley ↓ 13 and a V-pulley 26 provided at the lower end of the pivot shaft 25 of the peg 24 described above. Biasing member 108.
108Ali As shown in FIGS. 1 and 3, fitting holes 115 and 115 fit into the fitting protrusions 109 and 109A.
It is a roughly shaped lever with a hole A, and one biasing member 10
8 leg piece 108B is longer than the other leg piece 108C. This biasing member 108.108A is rotatably fitted into the fitting protrusion 109. Both leg pieces 108 fit into the workpiece 09A.
A connecting pin 116 connects B and 108C, and a pull pin 1 is attached to the leg piece 108B and the front plate 22.
A spring 118 is stretched between the two biasing members 108

Reference numeral 20 denotes an input shaft rotatably supported by the biasing members 108 and 108A, and this input shaft 120 is equipped with a drive wheel 121 and a gear 122 which are coated with rubber lining etc. to increase frictional resistance.
is attached, the gear 122 meshes with the gear 123 of the output shaft 111, and the drive wheel 121 is attached to the biasing member 108.1.
Due to the urging force of 08A, the guide rail 1 faces outward through the hole 124 (Fig. 1.3) bored in the side plate 105.
It is in pressure contact with 05. Since the rotation mechanism LOI has the above configuration, when the lifter 13 rises, the drive wheel 121 in pressure contact with the guide rail 15 rotates, and this rotation causes the input shaft 12 to rotate.
From gear king 22.123 output ill 11 to v pulley 113 via bevel gears 110 and 112, the roving bobbin 9 inserted into the peg 24 is rotated in the roving winding direction, that is, clockwise in FIG. Rotate in the direction.

A processing head 103 for processing the cut end 102 hanging down from the roving bobbin 9 is attached to a displacement mechanism 104 for displacing the processing head 103 between the working position and the non-working position, and the displacement mechanism 104 is connected to a parallel link as shown below. It consists of 1. In FIG. 3, reference numeral 125 denotes a louver, which is pivotally supported by a mounting shaft 126 installed so as to bridge between the left and right side plates 105, and 127.128
Of the 2.3 levers shown, the middle part of the second lever 127 and the lower end of the third lever 128 are pivoted to a bracket 129 attached to the front plate 22, and the upper ends of the respective levers 127 and 128 are There is a processing head 103 in the section.
A bracket 130 for mounting is pivotally mounted. Next 1
Reference numeral 31 denotes an operating lever, and as is clear from the drawing, the operating lever 131 is two levers that pass through a hole 132 bored in the front plate 22 and are sandwiched between the lower ends of the first and second levers 125 and 127. A cam follower 133 is attached to the rear end of the first operating lever 131. 134 is the second lever 127 and the operating lever 131
A spring is tensioned between the pivot point of , and a pull rod 135 installed as a bridge between both side plates 105, and this spring 134 causes the entire parallel link to rotate counterclockwise in FIG. peg 24
When the roving bobbin 9 is not inserted thereon, the second lever 127 hits a stopper 136 provided on the front plate 22, thereby restricting rotation beyond a certain limit. Finally, 137.137A is a cam plate, and a mounting plate 139 is attached to the horizontal crosspiece 138 horizontally suspended between the frames 14.
Slopes 137B to 137C, which correspond to the cam follower 133 and are spaced apart from each other by predetermined intervals 104A to 140B, are attached to the upper and lower ends of 9 so as to face each other. Since the displacement mechanism 104 has the above configuration,
When the lifter 13 moves up and down and the cam follower 133 rides on the cam plates 137, 137A, the operating lever 131
are pushed out against the spring toward the front (left side in FIG. 2), so the respective levers 125, 127, and 128 are positioned as shown by the imaginary line X1 in FIG. Set to the working position, cam plate 137, work 37A
If the roving bobbin 9 is not on the peg 24, the second lever 127 hits the stopper 136 as described above, and the respective levers 125. 127.128
is located as shown by the imaginary line X2 in FIG. become.

Finally, the processing head 103 will be explained.

The processing head 103 has a mounting plate 142 bent into a substantially arched shape attached to a bracket 130 pivoted to the upper ends of the second and third levers 127 and 128, and each plate is attached to each end of the mounting plate 142. It is being The processing head 103 has a bent substrate 143 as shown in FIGS. 1 and 3.
On the left side, that is, facing the rotational direction of the roving bobbin 9, comb-like scooping pieces 144 are formed at predetermined intervals, and the tips of the scooping pieces 144 are cut obliquely and are Top surface 1
45, the guide path 1 of the cut end 102 is located between each scooping piece 144.
It is 46. In addition, each scooping piece 144 extends diagonally forward straight as shown in FIG. 7, and when it comes into contact with the roving bobbin 9, a slight gap shown by α is created between the tip and the roving bobbin 9. This is done so that it does not come into direct contact with the roving bobbin 9. The opposite side of the scooping piece 144 is bent into an arc shape to form a caressing surface 147, and between the scooping surface 147 and the scooping piece 144, there are five or more recesses formed. The installation height of the processing head 103 is the same as that of the roving bobbin 9.
It is attached so as to correspond approximately to the end of winding on the roving frame 1.

The action will be explained below. As shown in FIG. 5, when the lifter 13 is at its lowest position, the cam follower 133 of the displacement mechanism 1O4 rides on the cam plate 137, so the processing head 103 is in the non-operating position as described above. When the roving bobbin 9 is transferred from the peg conveyor 4 and the lifter 13 rises, this rise causes the rotation mechanism 10 to
↓ is activated and the roving bobbin 9 on the bed 24 rotates clockwise in the roving winding direction in FIG.
As described above, the rotation of the rotation mechanism 101 is performed by moving the rubber-lined drive wheel 121 to the guide rail 15 by the pressure of the spring 118.
Since the spring 118 pressure is adjustable, the roving bobbin 9 can be smoothly rotated without any trouble such as slipping. As the lifter 13 rises, the cam follower 13
3 reaches the slope 137B of the cam plate 137, the displacement mechanism 1
04, the respective levers 125, 127, and 128, which were pulled by the spring 134 and were at the position shown by the imaginary line Xi, gradually swing counterclockwise in FIG. 2, and the cam follower 13
3 is just before the starting point 140A on one side of the intervals 140A-140B, each lever 125, 127, 128 is in an upright state as shown in FIGS. 2 and 3, and the processing head 1
The contact of the processing head 103 with the roving bobbin 9, where the processing head 103 comes into contact with the roving bobbin 9 and becomes the operating position, is due to the force of the spring 134. In addition, since the processing head 103 has only a portion of the scooping piece 144 and the caressing surface 147 in contact with the roving bobbin 9, and the contact area is small, the roving bobbin 9 rotates. Also, since there is a gap α between the tip of the scooping piece 144 and the roving bobbin 9, there is no risk that the tip will hit the rotating roving bobbin 9, and the roving can be moved smoothly. Rotate.

When the processing head 103 comes into contact with the roving bobbin 9 as described above, the cam follower 133 continues to rise during the interval 140A to 140B until the cam follower 133 rides on the next cam removal 37A at the top. As the thread bobbin 9 rotates, the caressing surface 147 caresses the outer periphery of the thread bobbin 9, and even when the cut end 102 of the roving is not unwound, the cut end 10
2 is surely pressed against the outer circumferential surface of the roving bobbin 9 to prevent it from unwinding afterwards.

Next, as shown in FIG. 6.7, the cut ends 102 of the rovings are unwound and, if they are hanging down, they are treated as follows. When the roving bobbin 9 rotates, the hanging cut end 102 is released from the roving bobbin 9 to form a balloon due to centrifugal force as shown by the imaginary line 102A, and in this state is rotated to the processing head 103. The cut end 102 is scooped up at a position extremely close to the release point 102B by any one of the plurality of scooping pieces 144, pulled up by the lifting surface 145 at the tip and guided to the guide path 146, and thereafter the cut end The roving yarn 102 is guided by the guide path 146 and wound in an orderly manner, and then stroked by the caressing surface 147 to ensure that it adheres to the roving bobbin 9 and is completely prevented from unraveling thereafter. As described above, the processing of the roving ends by the processing head 103 shown in this embodiment is performed using the plural scooping pieces 14.
4, the cut end 102 is scooped up at a position very close to (or coincides with) the point 102B where the cut end 102 is released from the roving bobbin 9, pulled up by the pulling surface 145, and guided to the guide path 146. As a result, the cut end 102 is not only wound up neatly in a layered manner similar to the way it is wound up in a rover, but also the upper end surface 1 of the guide path 146.
Since there is a large opening between 46A and the roving bobbin 9 (FIG. 6), the cut end 102 to be wound will not be damaged. Once the roving ends have been processed in this way, the cam follower 1
33 rides on the cam plate 137A again and the processing head 10
3 becomes a non-operating position, and the lifter 13 continues to rise to a predetermined position to move the roving bobbin 9 to the bobbin carriage 28.
The roving yarn is delivered to the bobbin hanger 29 and conveyed to the spinning frame 2 as described above, but since the cut end 102 is firmly attached to the roving bobbin 9 as described above, it must be unwound again during the conveyance. This eliminates problems such as thread breakage and fiber scattering in the spinning machine 2. In the description of the above embodiment, when the lifter 13 is at the lowest end, the cam follower 133 of the displacement mechanism 104 rides on the cam plate 137, and the processing head 103 is in the non-working position [Xl, and after gradually rising] Although the description has been given of the parts that are in contact with the rotating roving bobbin 9, the present invention is not limited to this, and the implementation of the present invention can be implemented in the following manner. The roving bobbin 9 is transferred by the transfer device 8 by rotation of the arm rod 10 so that it is transferred from the front side (diagonally downward side in FIG. 3) of the processing head 103 so as to be substantially directly opposed to it. When the plate 137 is removed and the lifter 13 is at its lowest position, the processing head 103 is positioned at the position X2 where the second lever 127 hits the stopper 16, and the roving bobbin 9 to be transferred is pushed back to move both of them. May be brought into contact.

Next, the embodiment shown in FIGS. 8 and 9 will be described. This embodiment was implemented, for example, in a wagon-type doffing machine shown in Japanese Patent Application Laid-Open No. 60-10593, where 201 is a doffing machine movably disposed along the front of the roving frame 200. Two sets of bevel bars 203 and 203A are attached to the frame 202 of the doffing machine 201 so as to be movable up and down by a suitable lifting mechanism. Further, in the frame 202, the roving bobbin 204 of the roving frame 200 is doffed and inserted into the peg 206 of the peg bar 203 which is descending.
Insert the empty bobbin 204A into A, take out the empty bobbin 204A from the descending bar 203A, and move it to the roving frame 20.
6 The peg 206 of the above-mentioned bed bar 203 is attached to the transfer bag @ 205 for insertion into the first
Similarly to the embodiment, the peg bar 20 is rotatably provided.
3 is rotated in the winding direction of the roving by an appropriate rotation mechanism. The processing head 103 is attached to the tip of a mounting lever 207 pivoted to a peg bar 203, and is displaced between an operating position and a non-operating position by a displacement mechanism 208, which will be described below. In this embodiment, the displacement mechanism 208 is composed of a spring 209 and a solenoid 210. The spring 209 biases the mounting lever 207 in the counterclockwise direction in FIG. , the solenoid 210 resists the spring 209 and the mounting lever 2
07 in the clockwise direction, and the processing head 103 is brought to the non-working position 11X1. As described above, the roving bobbin 204 is attached to the peg 206 of the descending bevel bar 203.
Insert and raise.

On the way, when the solenoid 2↓O is returned to its original position, the mounting lever 207 is pulled by the spring 209, and the processing head 103 comes into elastic contact with the roving bobbin 204 and becomes the working position as shown in Fig. 8. In this state, the roving By rotating the bobbin 204 in the winding direction of the roving, the ends of the roving are processed in the same manner as in the first embodiment. Note that the roving bobbin 204 may be rotated before the processing head 103 is displaced to the operating position.

Finally, a third embodiment shown in FIG. 10 will be described. In this embodiment, the processing head 103 is connected to the peg conveyor 2.
The rest is the same as the second embodiment, except for a rotation mechanism 233 which is attached to a frame 231 biased to the shaft 30 and rotates a roving bobbin 232, as is clear from the drawings.

As shown in the drawing, the peg conveyor 230 is rotatably mounted in correspondence with two rows of pegs 234, and two pairs of left and right processing heads 1 are provided in correspondence with the respective rows of pegs 234.
03 is provided. Reference numeral 235 designates a mounting lever pivotally supported on the frame 231, and the processing head 103 is mounted at the tip of the mounting lever 235. Each of the mounting levers 235 has a displacement mechanism 236.
The peg conveyor 230 is biased toward the center by a spring 237, and a stopper 238 prevents excessive rotation. 239 is a solenoid similar to the second embodiment, and each lever 235 is connected to a spring 237.
The processing head 103 is rotated in a direction away from the peg conveyor 230 against the pressure, and the processing head 103 is placed in a non-operating position. next,
The rotation mechanism 233 is configured as follows. The rotation mechanism 233 is a peg conveyor 230 as shown in the drawing.
A rotary belt 240 is rotatably provided on the frame 231 so as to be positioned on both sides of the motor 2.
41 to rotate each roving in the winding direction. The roving bobbin 232 inserted into the peg 234 of the peg conveyor 230 is stopped for a predetermined time in order to be transferred to the lifting device 6 (FIG. 5) as described above, and the roving bobbin corresponding to the rotating belt 240 is The lower part of the roving bobbin 232 is in contact with this, and the rotation of the motor 241 rotates each of the roving bobbins 232 in the roving winding direction, and then the solenoid 2
39 returns to its original position, the processing head 103 which was in the non-operating position is pulled by the spring 237 and comes into contact with the roving bobbin 232 to become the operating position, and thereafter the roving is processed in the same manner as in the above-mentioned second process and second embodiment. Process the edges.

Effects of the Invention As detailed above, in the present invention, a roving end processing device is provided in the middle of a conveyance path for conveying a roving bobbin doffed from a roving frame to a spinning frame via a predetermined route.

Since the roving end is processed as described above, if the cut end of the roving is not unraveled, the outer periphery of the roving bobbin is stroked with the stroking surface of the processing head and the subsequent unwinding is performed. Even in this case, since the contact surface with the roving bobbin is much narrower than in conventional devices, the roving on the outer peripheral surface will not be disturbed due to contact with the processing head. Furthermore, the present application.

In addition to the effect of preventing the cut end from unraveling as described above, if the cut end of the unwound roving is hanging down, one of the multiple scooping pieces may come loose from the roving bobbin. It is scooped up at a position very close to the free point of the cut end, pulled up on the pulling surface, guided to a guide path, and then guided by this and wound up, so that it is wound up in an orderly layered manner similar to the winding on a roving machine. Since the roving is stroked with the stroking surface and is not pressed down while hanging down like in conventional devices, troubles such as misfeeding are prevented, and a large opening is formed between the upper end of the guide path and the outer periphery of the roving bobbin. Therefore, the core portion is not damaged when the cut end is wound up. Furthermore, since a plurality of scooping pieces are provided in the shape of comb teeth, even if the unwinding part of the cut end fluctuates up and down, it can respond well and there is no scooping error, which is desirable for a roving end processing device. This invention satisfies all the requirements.
