Description

Must strip piecing devices based on AGV car

Technical Field

The utility model belongs to the technical field of spinning machine, especially drawing frame, strip and book combination machine and fly frame based on AGV car must a piecing devices.

Background

In the entire spinning mill, the slivers are transported between carding machines, drawing frames, sliver-lap combinations and roving frames. The transport is carried out by the sliver can carrying the sliver between the textile devices. The strands are stored in a sliver can with a certain length and weight. When the strand of beard in one can is used up, a new full can replaces the empty can with the used up strand of beard. In actual production, the replacement of the full can and the empty can is completed by a steward. The yarn-retaining device comprises a yarn-retaining drum, a yarn-retaining head and a yarn-retaining head, wherein the yarn-retaining drum is used for accommodating the yarn-retaining drum, the yarn-retaining head is used for accommodating the yarn-retaining drum, and the yarn-retaining head is used for accommodating the yarn-retaining drum.

The operation of such creels and sliver joints usually takes place at the creel position of the draw frame, roving frame and sliver lap combiner. The labor and time are wasted because the car stop worker undertakes the transportation of the empty cans and the full cans and the joint work of the fiber strands; in addition, the proficiency of the joints of each car stopper can affect the consistency of the strand joints, causing unnecessary quality fluctuation. With the development of intellectualization of spinning work, the method for transporting the fiber strands and the fiber strand joints by a car stop worker needs to be replaced by a more intelligent and automatic scheme. On one hand, labor can be saved; on the one hand, the consistency of the joint quality can be ensured.

In order to overcome the defects in the actual production, the utility model provides a technical solution. According to the scheme, the AGV car and the beard strip joint device are matched together to complete the automatic can replacement and beard strip joint processes, and manual transportation of cans and manual joints are replaced. The technical scheme has the obvious benefits that: automatic can replacement and beard strip joint are realized, the consistency of the quality of the beard strip joint is ensured, and labor is saved.

The utility model discloses in related:

the 'strands', also known as 'slivers', 'slivers' and 'fibre strips', are made from cotton fibres, viscose, wool, rayon and mixtures thereof. The utility model relates to a fiber sliver placed in a can, which is produced by a carding machine, a drawing frame or a combing machine.

The fiber strand column refers to a columnar shape formed by placing the fiber strand on the tray of the sliver can in a circle, and is called as the fiber strand column. The height of the whisker bars is reduced along with the reduction of the whisker bars in the sliver can.

"strand tail" means a tail end of a fiber strand that is cut or snapped to form a strand.

"full sliver" means a sliver containing sliver of a specified length or weight.

By "empty can" is meant a can with no strands or a small number of strands remaining.

An "AGV car" refers to an automated guided vehicle for transporting a can between various processes.

The utility model provides a technical scheme that its technical problem adopted is:

one or more strand piecing devices are arranged on a guide frame part of a drawing frame, a ribbon lap combination machine or a roving frame and are used for twisting the strand tail of a new full sliver can and the strand tail of a sliver can which is about to be used up together to form a piecing with the thickness as the original strand so as to ensure the continuous production of equipment.

The AGV carries cans among all processes: and conveying the full can produced in the previous process to a placing point of each can in the guide frame area, conveying the can with the strand being exhausted back to the previous process for continuously filling the strand, or conveying the empty can to a can station for waiting for filling the strand, and repeating the steps.

And a fiber strand state sensor on the fiber strand joint device monitors the fiber strand state of the sliver can in real time. When the strand inside the can is about to run out, the strand state sensor acquires this information and transmits it to the electronic control unit of the piecing device. The electric control part informs the splicing device to start to prepare the splicing, and simultaneously, the electric control part directly informs the strand splicing device to start splicing or informs the AGV car to start to prepare to transport the sliver by a host machine (a drawing frame, a ribbon lap combination or a roving frame); when the fiber strand grabbing component of the joint device grabs fiber strands of the sliver can to be used up, the AGV car transports the empty sliver can (allowing a small amount of fiber strands left in the sliver can) back to a sliver can warehouse or a sliver can station of the previous process; this, or another, AGV transports a new full sliver can from the previous process to the location of the original can (the can removed by the AGV). When a new full sliver can reaches a designated position (namely the original position of the can removed by the AGV car), the other sliver grabbing part of the joint device grabs the tail of the new full sliver can; the beard strip tails are randomly placed on the outer side of the sliver can, the sliver grabbing component of the joint device needs to drive the sliver can to slowly rotate by means of a sliver can driving wheel on an arm of the AGV, and the beard strip tails move along with the rotation of the sliver can until the beard strip tails are grabbed by the beard strip grabbing component; then, the two fiber strand grabbing parts send the grabbed fiber strand tails into the joint part to perform joint action, so that a joint as thick as the original fiber strand is formed.

As a preferred embodiment of the present invention, the beard strip connector device includes a first beard strip grabbing component, a second beard strip grabbing component, a beard strip connector component, a beard strip status sensor, and an electric control component. The sliver piecing device is located in the area of the creel part of the drawing frame, sliver lap combination machine and roving frame, preferably in the area above the horizontal plane of the top end of the can. There may be one strand connector device above each feed can or there may be one or more strand connector devices.

As a preferred embodiment of the present invention, the first beard strip gripping member is used for gripping a tail of a beard strip of a full sliver can. The second strand grasping part is used for grasping strands of an empty strand bobbin (a bobbin with the strands about to be used up) and forming a strand tail. The strand joint part is used for twisting the strand tails of the first strand grabbing part and the second strand grabbing part together to form a joint as thick and thin as the original strand.

As a preferred embodiment of the present invention, the beard strip joining device includes only one beard strip gripping member, one beard strip joining member and an electric control member. The sliver piecing device is located in the area of the creel part of the drawing frame, sliver lap combination machine and roving frame, preferably in the area above the horizontal plane of the top end of the can. There may be one strand connector device above each feed can or there may be one or more strand connector devices.

Detailed Description

Fig. 1 is a schematic illustration of a typical drawing frame with a sliver can. The draw frame L, which usually has 6 to 8 cans 3, is fed into the draw frame. The beard strips 2 of each can 3 are placed on a can tray 6 with a can spring 4 to form a rectangular beard strip column 5, the height of the beard strip column 5 is reduced along with the reduction of the beard strips 2 in the can 3, the weight of the beard strip column 5 is reduced, and the can tray 6 is gradually lifted under the thrust action of the compressed can spring 4, so that the top layer of the beard strip column 5 is always at the top end of the can 3. The can 3 is provided with a can pulley 7 and can be freely moved by the AGV car B. The sliver 2 is drawn from the sliver can 3, passes through a pair of sliver guide rollers 1 and enters a drafting part A of a drawing frame; after being drafted by the drafting part A, 6 to 8 of the fiber strands 2 fed from the can 3 form a fiber strand 2 of a preset weight, and the fiber strands 2 are placed in the can 3 layer by layer in a looping manner under the rotating looping action of the looping disc 8 to form a fiber strand column 5.

In the actual production at present, an operator feeds a can 3 filled with slivers into a drawing frame L to replace an empty can 3 with the slivers about to be used up, and manually twists the slivers 2 of the can 3 and the tails of new full cans together to form a joint, and when the joint is completed, manually removes the empty can 3. In the whole process, the removal and feeding of the sliver can 3 are both manually operated, and the splicing of the sliver is also manually finished. The operator undertakes the work of handling the joint of the can 3 and the sliver 2. In order to overcome the current defects, the embodiment is provided with a strand connector device C at the part L of the guide frame of the drawing frame and above the horizontal plane of the top end of the sliver can 3, and the strand connector device C is used for connecting the strand tail of the sliver can 3 to replace a manual connector. Meanwhile, the transport of the can 3 is performed by the AGV car B, instead of the current operator transporting the can 3.

FIG. 2 is a schematic view of a full sliver can with a sliver tail. A can 3 comprising: can pulley 7, can spring 4, can tray 6. The whisker band is placed on the upper surface of the can tray 6 to form a whisker column 5, and a section of whisker band is placed on the outer side of the can 3 to form a whisker band tail 10. This strand tail 10 is easily grasped.

Fig. 3 is a schematic view of a cartridge with an almost spent fiber strand. As the strands in the can 3 decrease, the height and weight of the strand column 5 also decrease. Because the weight of the beard strip column 5 is reduced, the compressed strip cylinder spring 4 lifts the strip cylinder tray 6, so that the beard strip column 5 is always positioned at the top end of the strip cylinder 3, and the advantage can ensure that the beard strip is easily grabbed.

Fig. 4 is a preferred embodiment of an embodiment of the present invention. The beard sliver junction device C is located in the area above the top level of the sliver can (G, GG), preferably in the area directly above the sliver can (G, GG).

The strand splicing device C comprises: a first strand grasping part 12, a second strand grasping part 13, a strand joint part 14, a strand state sensor 16, a joint device electrical control part 15, and a joint device C mounted on a slide rail 18 to be freely movable thereon. When the strand state sensor 16 detects that the strand 2 in the sliver can GG is about to run out, it sends a message to the electronic control unit 15 of the splice device. The electrical control unit 15 instructs the second strand grasping unit to start grasping the strand 2 of the strand package GG, ready to be fed into the strand joint unit 14. Next, the AGV car B holds the can GG, moves out of the current position, and conveys the can GG to a can station or a can bank of the previous process. Then, another AGV car B holds a new full can G from the previous process or can bank and transports it to the home position of can GG; when the sliver G reaches the home position of the sliver G, the first sliver grasping part 12 starts to grasp the sliver tail 10 of the sliver G, and during this grasping process, the sliver driving wheel 17 on the arm 11 of the AGV car B starts to drive the sliver G to rotate slowly in the direction S until the sliver tail 10 is grasped by the first sliver grasping part 12. Subsequently, the first and second strand grasping members 12 and 13 feed the strand tails (10, 2) to be grasped into the strand joint member 14, completing the joint.

AGV B of fig. 4 has two AGV wheels 11 for holding the can (G, GG) and four AGV wheels 9 for facilitating the travel of AGV B. The AGV car B holds the sliver can (G, GG) through the arm 11, and freely carries the sliver can (G, GG) to a designated destination under the action of the wheels 9. Preferably, the AGV has a transport can (G, GG) that is autonomously navigated by a predetermined map.

FIG. 5 is a schematic top view of an AGV car driving a can into rotation. The AGV vehicle B holds the sliver can G by two arms 11. The arms 11 of the AGV vehicle each have a can drive wheel 17. When the AGV vehicle B holds the sliver can G, the sliver can driving wheel 17 drives the sliver can G to rotate slowly in the direction S, and in this process, the strand tail 10 also moves along with the rotation of the sliver can G, so that the first strand grasping part 12 of the strand joint device C grasps the strand tail 10. An example of the direction of rotation is given by S in fig. 5, and the opposite direction of S is also optional.

FIG. 6 shows a method of splicing an AGV car to a sliver splicing device. The jointing method is that when the fiber strand 2 of the fiber strand drum GG is about to be used up, the fiber strand state sensor 16 is activated, and an electronic control component 15 of the jointing device C sends a command for starting to change the fiber strand drum and jointing; the strand splicing device C starts a splicing process, the second strand grabbing part 13 grabs the strand 2 of the sliver tube GG with the strand being about to be used up, and then the AGV car B moves out the empty sliver tube GG; the AGV vehicle B moves the full sliver can G into the position of the empty sliver can GG; the first beard strip grabbing part 12 grabs the beard strip tail 10 of the full bobbin G; the strand tails (2, 10) gripped by the first strand gripper unit 12 and the second strand gripper unit 13 are fed into the strand joint unit 14 to form a joint. In the whole joint process, the AGV vehicles B can be one vehicle or a plurality of vehicles can work together.

Various modifications, additions and substitutions for the specific embodiments described herein will occur to those skilled in the art without departing from the scope of the invention as defined by the accompanying claims.
