Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roving end processing device for a roving bobbin conveyed along a conveying path between a roving spinning machine and a spinning spinning machine. The end of the roving yarn is processed to facilitate the automation work.

Conventional technology and its problems At present, the doffing of the roving bobbin from the roving machine, the transporting operation of transporting the doffed roving bobbin to the spinning machine, and the empty hung by the transported roving bobbin and the creel of the spinning machine The Shino exchange work, which also exchanges bobbins, and the transport work, which returns the roving bobbins used in the spinning machine to the spinning machine, are all automated. In the above, for example, the cut end of the roasted yarn that has been automatically doffed has a weak holding force as it is lightly attached to the outer peripheral surface of the roving bobbin by the fluff, so that the cut end is in the middle of transportation or when performing Shino exchange. There is a danger that it will hang away from the outer peripheral surface, and once drooping occurs, the unraveling of the roving proceeds due to the weight or vibration of the hanging roving, and the roving end breaks off and adheres or scatters to peripheral devices. And cause various troubles.

For the purpose of preventing unwinding of the roving end, the present applicant has previously proposed untwisting prevention devices for roving end as Japanese Patent Application Laid-Open Nos. 62-282029 and 63-6122. However, these two conventional devices hold down the outer surface of the roving bobbin with a pressing device and rotate the roving bobbin in the roving direction in the course of transporting the doffed roving bobbin, and adhere to the outer surface. It is designed to hold down the cut end of the roving, which has a certain effect as a device for preventing unwinding of the cut end.However, if the cut end is already unwound and drooping, Since it is only pressed against the outer surface of the roving bobbin while it is lowered, the drooping state of the roving is not eliminated, and in the case of a full roving bobbin, it is used for tapping during Shino splicing performed at the time of Shino replacement. In addition to inconvenience, the roving bobbin comes into contact with the presser device with a large contact area and rotates, so that the roving surface is roughened.

Means for Solving the Problems In view of the above prior art, the present application rotates the roving bobbin in the roving direction in the middle of the transport path for transporting the roving bobbin between the roving machine and the spinning machine. A rotatable mechanism is provided, and by rotating the roving bobbin, a tooth-shaped scooping piece of a comb for scooping the roving end hanging down from the roving bobbin, and the scooped roving end on the outer peripheral surface of the roving bobbin. With a stroke surface to be stroked, in addition to preventing the unraveling of the roving end of the roving bobbin conveyed between the spinning machine and the roving machine, it effectively and appropriately treats the hanging roving end. is there.

The roving end processing device 100 of this embodiment is attached to the elevating device 6 in the transport path 5 configured as described above, more specifically, the lifter 13, and the roving end processing device 100 is transferred to the peg 24 of the lifter 13. The roving bobbin 9 is brought into contact with the roving bobbin 9 which is rotated in the roving direction of the roving bobbin 9 and the roving end 102 (FIGS. 6 and 7). It comprises a head 103 and a displacement mechanism 104 for displacing the processing head 103 between a working position in contact with the roving bobbin 9 and a non-working position away from the roving bobbin 9.

First, the rotation mechanism 101 is configured as follows. The following urging members 108 and 108A are rotatably fitted to one end of the lifter 13 (to a frame 106 fixed to the right side plate 105 in FIG. 1) at both front and rear ends.
A bearing member 107 having 109A is attached, and an output shaft 111 having a bevel gear 110 attached to a front end and a gear 123 attached to a rear end is rotatably supported on the bearing member 107. The bevel gear 110 meshes with a bevel gear 112 attached to the front plate 22, and the bevel gear 112 has a V pulley 11
3 is coaxially mounted, and a V belt 114 is wound between the V pulley 113 and a V pulley 26 provided at the lower end of the pivot 25 of the peg 24. As shown in FIGS. 1 and 3, the urging members 108 and 108A are substantially L-shaped levers having perforated fitting holes 115 and 115A fitted into the fitting protrusions 109 and 109A.
The leg piece 108B of one urging member 108 is longer than the other leg piece 108C. The urging members 108 and 108A are rotatably fitted to the fitting projections 109 and 109A, and both leg pieces 108B and 108C
Are connected by a connecting pin 116, and a spring 118 is stretched between a leg piece 108B and an engaging pin 117 attached to the front plate 22, so that the two urging members 108 and 108A are The biasing force can be arbitrarily adjusted by adjusting the position of the locking pin 117 to the elongated hole 119 formed in the front plate 22 so as to be freely adjustable. ing. Reference numeral 120 denotes an input shaft rotatably supported by the urging members 108 and 108A. The input shaft 120 is provided with a drive wheel 121 and a gear 122 having rubber lining or the like to increase frictional resistance. Meshes with the gear 123 of the output shaft 111, and the drive wheel 121 faces the outside through a hole 124 (FIGS. 1, 3) formed in the side plate 105 by the urging force of the urging members 108 and 108A. Is pressed against. Since the rotation mechanism 101 has the above configuration, when the lifter 13 rises, the drive wheel 121 that is in pressure contact with the guide rail 15 rotates, and this rotation is performed by the input shaft 120, the gear 122, and the output shaft 111 by the bevel gear.
The roving bobbin 9 which is transmitted to the V pulley 113 via 110 and 112 and is inserted into the peg 24 is rotated in the roving direction of the roving, that is, clockwise in FIG.

A processing head 103 that processes the cutting end 102 hanging from the roving bobbin 9 is attached to a displacement mechanism 104 that displaces the processing head 103 between the working position and the non-working position.
The displacement mechanism 104 is made up of the following parallel links.
In FIGS. 1 to 3, reference numeral 125 denotes a first lever, which is pivotally supported by a mounting shaft 126 mounted so as to bridge between the left and right side plates 105, and of the second and third levers indicated by 127 and 128. The second lever 127 has an intermediate portion, and the third lever 1
28 is a bracket whose lower end is attached to the front plate 22
A bracket 130 is pivotally mounted on the upper end of each of the levers 127 and 128, and a bracket 130 on which the processing head 103 is mounted. Next, 131 is an operation lever, and the operation lever 131 is two levers as apparent from the drawing.
The first and second levers 125 and 127 are pivotally attached to the lower ends of the first and second levers 125 and 127 so as to sandwich them.
At the rear end, a cam follower 133 is attached. 134
Is a pivot rod between the second lever 127 and the operating lever 131, and a pulling rod 1 attached so as to bridge between both side plates 105.
The parallel link is urged by the spring 134 so that the entire parallel link rotates counterclockwise in FIG. 2, and the roving bobbin 9 is not inserted on the peg 24. In such a case, the second lever 127 hits the stopper 136 provided on the front plate 22 to limit the rotation of the second lever 127 beyond a certain limit. Finally, reference numerals 137 and 137A denote cam plates. A mounting plate 139 is mounted on a horizontal rail 138 which is suspended between the frames 14.
At the upper and lower ends, the slopes 137B to 137C corresponding to the cam follower 133 and having predetermined intervals 140A to 140B are attached to each other. Displacement mechanism
Since 104 has the above configuration, when the lifter 13 moves up and down and the cam follower 133 rides on the cam plates 137 and 137A,
Since the operating lever 131 is pushed out to the front (left side in FIG. 2) against the spring, each of the levers 125, 127, 12
8 is located as shown by the imaginary line X1 in FIG. 2 and the processing head 103 to be described later is in the inoperative position, and when it comes off the cam plates 137, 137A, that is, is pulled by the spring 134 between the above-mentioned intervals 140A to 140B, If there is no roving bobbin 9 on the peg 24, the second lever 127 hits the stopper 136 as described above, and the respective levers 125, 127, 128 are located as shown by the phantom line X2 in FIG. Further, when the processing head 103 described later comes into contact with the roving bobbin 9 to be in the operating position, the levers 125, 127, and 128 are in an upright state as shown in the drawing.

Finally, the processing head 103 will be described. The processing head 103 has a bracket 130 pivotally attached to the upper ends of the second and third levers 127 and 128, and a mounting plate 142 bent in a substantially arcuate shape, and one mounting plate 142 at each end of the mounting plate 142. ing. The processing head 103 picks up the comb teeth at predetermined intervals so as to face the left side of the bent substrate 143 as shown in FIGS. 1 and 3, that is, in the direction of rotation of the roving bobbin 9. A piece 144 is formed, and the tip of the scooping piece 144 is cut off obliquely to form a pull-up surface 145, and a space between the scooping pieces 144 serves as a guide path 146 for the cut end 102. Each scooping piece 144 extends straight and diagonally forward as shown in FIG.
When a contact is made between the tip and the roving bobbin 9, a slight gap is formed between the leading end and the roving bobbin 9 so as not to directly contact the roving bobbin. The opposite side of the scooping piece 144 is bent in an arc to form a rubbing surface 147, and a concave portion is formed between the rubbing surface 147 and the scooping piece 144, and configured as described above. The processing head 103 is mounted in such a manner that its mounting height substantially corresponds to the end of winding of the roving bobbin 9 in the roving machine 1.

The operation will be described below. When the lifter 13 is at the lowermost end as shown in FIG. 5, since the cam follower 133 of the displacement mechanism 104 rides on the cam plate 137, the processing head
103 is in the inoperative position as described above. When the roving bobbin 9 is transferred from the peg conveyor 4 and the lifter 13 rises, the rising mechanism activates the rotating mechanism 101 to move the roving bobbin 9 on the peg 24 clockwise in FIG. At this time, the processing head 103 has not yet contacted the roving bobbin 9. The rotation of the rotation mechanism 101 is performed by the rubber-lined drive wheel 121 as described above.
The pressure of the spring 18 makes pressure contact with the guide rail 15 and the pressure of the spring 118 is adjustable, so that the roving bobbin 9 is smoothly rotated without troubles such as slippage. When the cam follower 133 reaches the slope 137B of the cam plate 137 as the lifter 13 rises, the displacement mechanism 104 is pulled by the spring 134, and the respective levers 125, 127, 128 at the position indicated by the imaginary line X1 gradually move to the first position. In FIG. 2, it swings counterclockwise, and the cam follower 133
Immediately before the starting point 140A on one side of A to 140B, as shown in FIGS. 2 and 3, the levers 125, 127 and 128 are in an upright state, and the processing head 103 comes into contact with the roving bobbin 9 and acts. Position. Since the contact of the processing head 103 with the roving bobbin 9 is performed by the spring 134 force, by setting the spring 134 force to a desired optimum value, a light and elastic contact pressure can be obtained, and the processing head 103 Since only a part of the upper piece 144 and the stroke surface 147 are in contact with the roving bobbin 9, the contact area with the roving bobbin is much smaller than that of the conventional device. There is no gap between the tip of the scooping piece 144 and the roving bobbin 9 without roughening the outer periphery of the yarn bobbin.
As a result, there is no risk that the tip of the roving bobbin 9 will be pushed into the rotating roving bobbin 9, and the roving yarn bobbin 9 rotates smoothly.

When the processing head 103 comes into contact with the roving bobbin 9 as described above, the cam follower 133 has the next cam plate 137A on the upper side.
As it rises as it is during the interval 140A to 140B until it rides on, the rotation of the roving bobbin 9 strokes the stroked surface 147 around its outer periphery, and the cut end 102 of the roving is not unwound. Even if the cut end 102 is
To prevent it from unwinding afterwards.

Next, as shown in FIGS. 6 and 7, when the cut end 102 of the roving is unwound and is hanging, the processing is performed as follows. When the roving bobbin 9 rotates, the hanging cut end 102 is released from the roving bobbin so as to form a balloon by centrifugal force as shown by a virtual line 102A, and when the roving bobbin 9 rotates to the processing head 103 in this state. The cut end 102 is scooped up by one of a plurality of scooping pieces 144 at a position very close to the free point 102B, pulled up at the leading pulling surface 145 and guided to the guide path 146, and thereafter, the cut end 102 Is guideway 14
It is guided by 6 and wound neatly, then stroked on the stroke surface 147 and adheres firmly to the roving bobbin 9, and unwinding thereafter is completely prevented. As described above, the processing of the roving end by the processing head 103 shown in this embodiment is performed at any one of the plurality of scooping pieces 144 so that the cut end 102 is released from the roving bobbin 9. It is scooped up at a position very close to 102B (it may coincide with it), pulled up on the pulling surface 145 and guided and wound on the guide path 146, so that the wound cut end 102 is the same as the winding in the roving machine 1. Not only is it wound up in a layered manner, but also a large opening is formed between the roving bobbin 9 and the end surface 146A of the guide path 146 opposite to the pulling surface 145 (FIG. 6). Edge 102 is not damaged. When the processing of the roving end is completed in this way, the cam follower 133 rides on the cam plate 137A again, and the processing head 103 becomes the non-operating position, the lifter 13 ascends to the predetermined position, and moves the roving bobbin 9 to the bobbin cap. It is delivered to the bobbin hanger 29 of the carriage 28 and transported to the spinning machine 2 as described above.
Since the fibers 2 are securely adhered to the roving bobbins 9, the yarns are not unwound in the course of conveyance, and problems such as thread breakage and fiber scattering in the spinning machine 2 are eliminated. In the description of the above embodiment, when the lifter 13 is at the lowermost end, the cam follower 133 of the displacement mechanism 104 rides on the cam plate 137, the processing head 103 is at the non-operating position X1, and the processing head 103 is gradually raised and then rotated. Although the description has been given of the one that comes into contact with the roving bobbin 9 described above, the present invention is not limited to this, and the present invention is not hampered by the following. The transfer of the roving bobbin 9 by the transfer device 8 is performed by rotating the arm rod 10 on the front side of the processing head 103 (third side).
Since the cam plate 137 is removed and the lifter 13 is at the lowermost end, the second lever 127 is moved to the position of X2 where the stopper 16 is contacted. The two may be brought into contact with each other by positioning the head 103 and pushing it back with the roving bobbin 9 to be transferred.

Next, the embodiment shown in FIGS. 8 and 9 will be described. This embodiment is implemented, for example, in a wagon-type doffer disclosed in Japanese Patent Application Laid-Open No. 60-10593, and 201 is a doffer movably arranged along the front surface of the roving machine 200. The doffing machine
The frame 202 of 201 has two pairs of peg bars 203 and 203A,
It is mounted so as to be able to move up and down by an appropriate lifting mechanism. In the frame 202, the roving bobbin 204 of the roving machine 200 is doffed and inserted into the peg 206 of the descending peg bar 203, and the empty bobbin 204A is inserted into the peg 206A and the peg bar 203A descends. The empty bobbin 204A from the roving machine 200
A transfer device 205 for insertion into the device is attached. The peg 206 of the peg bar 203 is rotatably provided in the same manner as in the first embodiment, and rotates in the roving winding direction by a suitable rotating mechanism while the peg bar 203 is raised. The processing head 103 has a mounting lever 207 pivotally supported by the peg bar 203.
And is displaced between an operating position and a non-operating position by a displacement mechanism 208 described below. In this embodiment, the displacement mechanism 208 includes a spring 209 and a solenoid 210. The spring 209 urges the mounting lever 207 counterclockwise in FIG. 8, and the mounting lever 207 hits a stopper 211 to restrict rotation. Then, the solenoid 210 pushes the mounting lever 207 clockwise against the spring 209, and sets the processing head 103 to the non-operation position X1. As described above, the roving bobbin 204 is inserted into the peg 206 of the descending peg bar 203 and is raised, and when the solenoid 210 is restored to the old one on the way, the mounting lever 207 is pulled by the spring 209 and the processing is performed. The head 103 resiliently contacts the roving bobbin 204 and assumes the operating position as shown in FIG.
In this state, by rotating the roving bobbin 204 in the roving direction of the roving, the roving end processing is performed in the same manner as in the first embodiment. The roving bobbin 204 can 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 a peg conveyor 230.
The structure is the same as that of the second embodiment except for a rotation mechanism 233 for rotating the roving bobbin 232, as is apparent from the drawing. As shown in the drawing, the peg conveyor 230 is rotatably mounted so as to correspond to two rows of pegs 234, and is provided with a pair of left and right processing heads 103 corresponding to each peg 234 row. Two
Reference numeral 35 denotes an attachment lever pivotally supported by the frame 231. The processing head 103 is attached to the tip of the attachment lever. Each of the mounting levers 235 is urged toward the center of the peg conveyor 230 by a spring 237 constituting a displacement mechanism 236, so that the stopper 238 controls excessive rotation. Reference numeral 239 denotes a solenoid similar to that of the second embodiment. Each of the levers 235 is rotated in a direction away from the peg conveyor 230 against the spring 237 to set the processing head 103 in a non-operation position. Next, the rotation mechanism 233 is configured as follows. As shown in the drawing, a rotating mechanism 233 is provided on both sides of the peg conveyor 230 and rotatably provided with a rotating belt 240 on the frame 231.
The rotating belt 240 is rotated by the motor 241 in the roving winding direction. The roving bobbin 232 inserted in the peg 234 of the peg conveyor 230 is stopped for a predetermined time to be transferred to the elevating device 6 (FIG. 5) as described above, and the roving bobbin corresponding to the rotary belt 240 The lower part of 232 contacts this, and the rotation of the motor 241 causes the roving bobbin 2
By rotating each of 32 in the roving winding direction, and then the solenoid 239 is returned to the old state, the processing head 103 at the non-operation position is pulled by the spring 237 and comes into contact with the roving bobbin 232 to become the operation position. Thereafter, the processing of the roving end is performed in the same manner as in the first and second embodiments.

Effects of the Invention As described in detail above, the present application provides a roving end processing device in the middle of the roving bobbin transport path of the roving and spinning machines, and performs the processing of the roving end as described above. Therefore, if the cut end of the roving is not unwound, the outer periphery of the roving bobbin can be stroked on the stroke surface of the processing head to prevent and prevent subsequent unwinding. In addition to the effect of preventing unwinding of the cut end, when the cut end of the unwound roving is hanging, one of the plurality of scooping pieces is free from the roving bobbin. By scooping up the cut end, it can be rolled up neatly in a layered manner on the outer peripheral surface of the roving bobbin in the same manner as in the roving machine, and stroked on the stroked surface. ,
It is possible to prevent the roving bobbin from being conveyed while hanging down, and to prevent a trouble of misfeeding at the time of the splicing. In addition, since a plurality of scooping pieces are provided in the shape of a comb tooth, even if the unwinding portion of the cut end fluctuates up and down, there is no scooping error corresponding to this, and the roving end processing device It is an invention that satisfies all the requirements.
