Description

[Detailed description of the invention] Industrial field of application This invention connects a plurality of carding machines and one drawing machine,
This invention relates to a continuous spinning device in which a carding machine and a drawing machine are connected, and the sliver spun from each carding machine is supplied to the draft zone of the drawing machine to perform doubling.

2. Description of the Related Art Conventional continuous spinning devices of this type are generally manufactured in Japanese Patent Publication No. 38-2.
As disclosed in Publication No. 5172 and Japanese Utility Model Publication No. 46-34341, a sliver conveying belt and a table are arranged behind the drawing machine, and a plurality of carding machines are lined up along these belts and tables. The sliver spun from each carding machine is placed directly on a belt or table and fed to the draft zone of the drawing machine. In addition, in a combination of a carding machine and a drawing machine, a sliver feeding device was developed in which the carding machine automatically conveys the full can containing sliver to the drawing machine.
It is disclosed in the publication No.

Problems to be Solved by the Invention In the case of the apparatus described in the above-mentioned Japanese Patent Publication No. 38-25172, etc., the same number of carding machines as the number of doublings of the sliver is required, and increasing the number of doublings increases the cost. In addition, the spinning capacity of the carding machine becomes larger than that of the drawing machine, and the spinning speed of the carding machine must be lowered to a speed considerably lower than its capacity, which poses the problem of becoming extremely uneconomical. Ta.

For example, if the spinning capacity of the drawing machine is 600 m/min and the spinning capacity of the carding machine is 150 m/min, and the number of doubling slivers is 8, the spinning speed of the carding machine will be 50% of its capacity. had to be lowered. In addition, since the sliver spun from the carding machine is directly supplied to the drawing machine, the sliver spun from the carding machine is once stored in a can, and then the sliver inside the can is pulled out and supplied to the drawing machine. Compared to the single method, the fiber hooks of the sliver fed to the drawing machine are reversed (rear end hook), and as a result, the drawing sliver is transferred to the second
When the fibers are sequentially supplied to a drawing machine, a roving frame, and a fine spinning frame, the hooks of the fibers supplied to the draft zone of the fine spinning frame become front end hooks, resulting in an unfavorable draft condition of the fibers. Therefore, as previously disclosed in Japanese Patent Publication No. 40-25177, a can containing filamentous sliver is turned upside down and the sliver is pulled out from the bottom when the sliver is housed, and then transferred to a second ridge line machine, etc. Attempts have been made to supply such equipment, but the equipment is complicated and expensive, and the reality is that it is not yet sufficient.

On the other hand, in the case of the device described in Japanese Patent Publication No. 39-16220, the full can containing sliver is automatically conveyed to the drawing machine process in the carding process, and the can is filled with sliver in the carding process. Since the sliver is drawn out from the can and fed, it does not have the problems of the conventional continuous spinning equipment mentioned above. However, although this equipment can automatically transport a full can, it is difficult to feed the sliver to the drawing machine. It is far from being a continuous spinning device because it cannot automatically supply the spinning cans, and there are practical problems in that it requires a large number of cans and increases equipment costs.

Means for Solving the Problems The present invention solves the above problems, makes it possible to fully utilize the spinning capacity of each carding machine, and allows the fiber hooks of the drawing machine fed sliver to be the front end hooks. The purpose is to provide a continuous spinning device that can automatically feed sliver spun by a cotton machine to a drawing machine continuously. The drawing machine is equipped with a sliver cutting device located at The can feed conveyor is arranged in a substantially semi-circular arc shape below the sliver supply conveyor, and a can rotating device is provided which can rotate full cans from the feed can placement position of the can feed conveyor to the inlet side. The sliver end portion located at the top of the full can is pulled out by moving between an outlet position near the top of the full can rotated by the can rotating device and a delivery position above the full can. The present invention is characterized in that it comprises a suction nozzle having a sliver shape, and a sliver gripping and supplying device configured to receive the end of the sliver from the suction nozzle at the delivery position and supplying it onto the sliver supply conveyor.

In each carding machine, the can in the sliver storage position is filled with the sliver being fed.

The can changing device operates to move the full can onto the can transport conveyor, and move the empty can to a can storage position, thereby storing the sliver in the empty can. In this case, the full can of sliver is cut by a sliver cutting device, the sliver end of which is positioned at the top of the full can.

The full cans transferred onto the can conveyor are conveyed to the can feed conveyor behind the drawing machine. In the can feed conveyor, the full can is first moved to the rotation position of the can rotation device, and the suction nozzle is moved to a position near the top of the full can at the rotation position,
Air is sucked through this suction nozzle. In this state, the full can is rotated by the can rotating device, and as a result, when the sliver end located at the top of the full can is opposed to the suction nozzle, the sliver end is attracted to the suction nozzle. The rotation of the full can is then stopped and the suction nozzle is moved to the upper transfer position to pull the sliver end upwards. The sliver end is then transferred to a sliver gripping and feeding device, which feeds it onto a sliver feeding conveyor, which feeds the full can of sliver into the draft zone of the drawing machine. Further, the full can is moved by one can when the preceding can becomes empty or close to the empty can, whereby the preceding empty can is sent to the can transport conveyor. The empty cans delivered onto this can transport conveyor are sent to the can exchange device of each carding machine.

Further, a bypass passage 64 for connecting the rain roller conveyor 61.62 is provided near the front end of the roller conveyor 61.62. A can 1 on the roller conveyor 62 is located at a position corresponding to the bypass passage 64.
A can return device 65 is provided for moving the cans through the bypass passage 64 onto the roller conveyor 61. This can return device 65 is constructed by providing a pressing tool 67 on a piston rod 66a of an air cylinder 66.
The can 11 is moved by pushing the side of the can 11.

69a and 69b are emitters and receivers for detecting that the can 11 has been transferred to the return position 68;
a photocell for detecting whether 1 is full or not;
Reference numeral 71 is a phototube that detects whether there is a full can Ilb at the receiving position 38, and when there is a full can Ilb at the receiving position 38, when the can 11 is moved to the return position 68, the air cylinder 66 is activated to return it. Rank! ! 68 cans 11 are pushed onto the roller conveyor 61, and when there is no full can llb at the receiving position 38, when the empty can 11a is moved to the return position, the air cylinder 66 is actuated to push the can lla onto the roller conveyor 61. It is configured to be extruded. In addition.

The can conveyor 4 may be constructed of a single roller conveyor that can rotate forward and backward, and may be controlled so that full and empty cans are alternately discharged onto the roller conveyor.

In the above configuration, when the can 11 in the sliver storage position 8 becomes full can 11b in each carding machine 2, the photocell 11 indicates that there is an empty can lla in the standby position @10.
After confirmation by 9, the air cylinder 15 is operated to push out the full can llb to the extrusion position 12 and at the same time supply the empty can lla to the sliver storage position 8. By this can exchange operation, the coiler wheel 7 and full can
The transitional sliver between the empty cans 11a and 11a is held between the sliver tray of the empty can 11a and the coiler plate 5, and between the full can 11b and the sliver holding plate 26, and then the empty can 11a is rotated by the rotary table 9, so that the empty can 11 is
The sliver end of the full can Ilb is cut on the la side, so that the sliver end of the full can Ilb hangs to the upper side of the full can Ilb.
After confirming with the light receiver 23b that there is no Ilb, the air cylinder 17 is activated to push out the full can 11b from the extrusion position 12 to the discharge position 24, and the extruded full can Ilb is transferred to the roller conveyor 61. The can delivery device 63 and roller conveyor 62 transport the cans in the direction of the arrow in FIG.

When the light receiver 69b detects that the full can 11b has been transferred to the return position 68, the receiving position i! When the phototube 71 detects that there is a full can 11b at the return position 68, the rotation of the roller conveyor 62 is temporarily stopped, and while the roller conveyor 62 is stopped, the air cylinder 66 is activated to return the full can 11b to the return position 68. is returned onto the roller conveyor 61. In general, by balancing the overall production capacity of each carding machine 1 and the production capacity of the drawing machine 2, the operation of returning the full cans Ilb is eliminated or reduced. be able to. In addition, a pool place for full cans 11 is provided between the return position 68 and the receiving position 38, and the above full cans 11
The return operation b may be eliminated. When the full can Ilb is moved to the return position 68, if the phototube 71 detects that there is no full can Ilb at the receiving position 38, the roller conveyor 62 continues to rotate, and the full can Ilb is Transferred to receiving position 38.

Next, when a detector such as a phototube (not shown) detects that the first sliver in the feed cans III row of the drawing machine 2 has run out or there is little left,
The can transfer arm 36 and the roller conveyor 33 simultaneously rotate to move the full can Ilb on the turntable 41 onto the roller conveyor 33, and at the same time move the full can Ilb onto the roller conveyor 33 and into the receiving position ffl.
! Move the 38 full cans llb onto the turntable 41.

Further, the empty cans lla on the roller conveyor 33 are sent onto the roller conveyor 61 of the can transport conveyor 4, and each feed can llc is moved by one can. When the can transfer arm 36 rotates 90 degrees and stops as described above, and the full can Ilb is moved onto the turntable 41, the rotation device 43 is actuated by a command to complete the operation, as shown by the solid line in FIG. The suction arm 45, which had been waiting at the retracted position shown in FIG. 3, rotates counterclockwise in FIG.
is lowered from the raised position via the swinging device 44 to the lowered position shown by the imaginary line in FIG. Suction by the suction nozzle 46 begins. Further, when the suction arm 445 reaches the lowered position and a limit switch (not shown) is activated, the turntable 41 rotates in response to the detection command, rotating the full can Ilb in the direction of the arrow, and as a result, the suction arm 445 hangs down from the full can Ilb. The end of the sliver is attracted to the wire mesh surface of the suction nozzle 46. When a detection device such as a phototube attached to the suction nozzle 46 detects the sliver captured by the suction nozzle 46,
When the rotation of the turntable 41 stops, the swinging bag [44] is activated by the detection signal, and the suction arm 45 rises from the lowered position and pulls out the sliver completely. When the suction arm 45 reaches the raised position, , the turning device 43 is activated, and the suction arm 45 turns clockwise in FIG. 3 and returns to the retracted position shown by the solid line in FIG. 3. As a result, the sliver pulled up from the full can Ilb is introduced between the fixed side gripping roller 53 and the movable side gripping roller 56 of the sliver gripping and supplying device 47 which is held in an open state at the gripping position as shown in FIG. be done. Next, when a detection device 58 such as a phototube detects the sliver introduced between the gripping rollers 53 and 56, the movable gripping roller 56 is moved by the detection signal.
The sliver is rotated clockwise in FIG. 4 via a swing motor (not shown), and the pulled up sliver is gripped by the movable gripping roller 56 and the fixed gripping roller 53.

Furthermore, when the sliver is gripped by the gripping rollers 53 and 56, the suction nozzle 46 and the suction arm 45, which were sucking the end of the sliver, stop the suction sources, and the tip of the sliver is pulled up onto the lower receiving plate. (Illustration omitted) Falling upward. When the tip of the sliver is released in this way, the reverse feed motor M1 is started and the friction roller 55
and 54, the fixed side gripping roller 53 and the movable side gripping roller 56 rotate in reverse to pull the gripped sliver back toward the full can 11b, and when the tip of the sliver is detected by a detection device 58 such as a phototube, Motor M for reverse feed
1 stops, and the gripping rollers 53 and 56 also stop. By pulling back the sliver, the amount of protrusion of the sliver end toward the delivery side of the gripping rollers 53 and 56 becomes extremely short. In this way, the sliver gripping and supplying device 47 that grips and pulls back the sliver pulled up from the full can llb has its swing arm 52 and gripping rollers 53, 56 connected to the next can transfer arm 36 and roller conveyor 3-. It waits at the gripping position until rotation 3 is performed. After that, the can transfer arm 36 and the roller conveyor 33 are rotated,
When one of the feed cans LLC becomes empty and the end of the sliver of the feed can LLC approaches the feed rollers 48a and 48b and a command is issued from a succession command means such as a phototube (not shown), that command is issued. Based on this, the swing motor 51 is activated, and the swing arm 52 and the grip rollers 53 and 56, which were waiting at the grip position, move forward to the supply position. In this case, gripping rollers 53 and 56
Because the length of the sliver end protruding toward the delivery side is short, it does not bend during the movement of the gripping rollers 53 and 56, and when the gripping rollers 53 and 56 reach the feeding position, The friction roller 54 fixed to the shaft end of the sliver comes into pressure contact with the rotating delivery friction roller 60, causing the gripping rollers 53 and 56 to rotate in the normal direction, and the gripped sliver is sent forward, and the tip of the sliver is It is sent between feed rollers 48a and 48b. In this way, the new sliver is fed to the feed roller 48a of the drawing machine 2.
, 48b, this feed roller 48a
A screw guide 49 arranged on the upstream side of the sliver rotates once by the rotation of the motor M2, and laterally moves the other sliver being spun by one pitch. In addition, when a new sliver is supplied to the drawing machine 2 as described above, the starting end of the sliver and the ending end of the sliver generally do not match the phase accurately, resulting in variations in the thickness of the spun sliver. However, this variation in the thickness of the sliver is removed by an autoleveler, making it possible to spin a uniform sliver. Further, when a new sliver is gripped between the feed rollers 48a and 48b, the movable gripping roller 56 and its swinging rod 57 are opened via a swinging motor (not shown), and the gripping rollers 53 and 56 are opened via a swinging motor (not shown). The sliver extracted from the screw guide 49 enters into the groove on one side of the screw guide 49 which is vacated by the lateral movement, and is continuously supplied.

Further, when a new sliver is pulled out from the gripping rollers 53 and 56, the gripping rollers 53 and 56 and the swinging arm 52
returns from the supply position to the gripping position via the swing motor 51, the gripping rollers 53 and 56 stop, and the movable gripping roller 56 remains open until the next time the sliver is supplied. After that, by rotating the can transfer arm 36 on the side of the drawing machine 2, the full can Ilb is placed on the turntable 41 at the exit position.
Each time the sliver is transferred upward, the suction arm 45, the sliver gripping and feeding device 47, etc. operate in the same manner as described above to automatically feed a new sliver between the feed rollers 48a and 48b of the drawing machine 2.

Next, the roller conveyor 61 of the can conveyor 4
The empty cans lla and full cans llb pushed upward are moved backward on the roller conveyor 61. When the light receiver 22b detects that these cans 11 have been moved to the supply position 21 corresponding to each carding machine 1, the phototube 19 detects that there is no empty can lla at the standby position 10. In this case, the can 11 is an empty can 11.
After confirming that it is a with the phototube 20, the roller conveyor 61 is temporarily stopped and the air cylinder 1
3 to take the empty can lla from the supply position 21 into the standby position 10. In this case, when there is an empty can lla in the standby position 10 or when the can 11 is full
When , the rotation of the roller conveyor 61 is continued,
The cans are circulated on the conveyor 4. In addition,
By balancing the capacities of the carding machine group 1 and the drawing machine 2, it is possible to eliminate or reduce the number of empty cans llb circulated by the can conveyor 4.

The sliver gripping and supplying device 47 in the above embodiment has a pair of gripping rollers 53 and 5 as the sliver gripping means.
6 has been described, the present invention is not limited to this, but as shown in FIG. ) and when pulling back the sliver, the sliver end.

By drawing the sliver into the inside of the apron-equipped gripping rollers 53A and 56A, the sliver will not protrude to the delivery side of the gripping rollers 53A and 56A, and bending on the upper surface of the sliver can be completely eliminated.

Further, the sliver gripping and supplying device 47 of the above embodiment includes one gripping roller 53.

56, the driving means for reverse feeding is a motor M1 and a friction roller 5.
5, and the drive means for feeding is constituted by the friction roller 54 fixed to the shaft end of the gripping roller 53, the friction roller 6o disposed on the drawing machine 2 side, etc., but the present invention is limited to this. Instead, the gripping rollers may be rotated forward and backward, respectively, via a common motor provided on the swing arm and capable of forward and reverse rotation, and transmission means such as a pulley and a belt. In addition, the gripping roller is attached to the swinging arm,
It goes without saying that these gripping rollers may be provided on a moving body that moves linearly toward the drawing machine 2, and that the design of each part may be changed as desired.

In addition, in the present application, the sliver cutting device is configured such that the end of the sliver is cut on the upper surface of the full can of sliver, and a disc-shaped or rod-shaped suction nozzle is positioned parallel to the upper surface of the full can of sliver. Alternatively, the end of the sliver may be sucked by rotating the full can.

Effects of the Invention As described above, in the present invention, the sliver spun by a carding machine is stored in a can, and the sliver is:
A can is conveyed to the can feed conveyor of the drawing machine, and the sliver drawn from the full can is fed to the drawing machine, so the fibers of the sliver fed to the drawing machine can be used as the front end hook. As a result, even in continuous spinning equipment, if the normal spinning process is used, in which the sliver from the drawing machine is loaded into the drawing machine and then loaded into the roving frame and spinning frame, the fibers that are fed into the draft zone of the spinning frame are hooked. The rear end hook can be used to create a good draft. In addition, since the spun sliver from each carding machine is stored in a can, and these cans are conveyed and supplied to the drawing machine, the spinning capacity of each carding machine and drawing machine is The spinning speed of the carding machine can be set to the optimal capacity of the carding machine without being limited by the drawing machine, and as a result, the number of carding machines in the continuous spinning machine can be reduced. This can reduce the overall cost. In addition, even if the full can is transported and set on the drawing machine as described above, the end of the sliver of the full can sent out from the carding machine is positioned at the top of the can, and the end of the sliver is Since the sliver is drawn upward in the drawing machine and the end of the sliver is mechanically fed to the drawing machine, the continuous supply of the sliver to the drawing machine can be automated, resulting in labor savings. . Further, since the suction nozzle rotates the suction can to extract the end of the sliver, the sliver can be extracted using a small suction nozzle.
