Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a can conveying system in a spinning factory.

[Prior Art] Generally, in a spinning factory, from the acceptance of raw cotton to the mixed cotton,
Yarn is produced through various processes such as card, comb preparation, comb, kneading I, kneading II, roving, spinning and rewinding.

Conventionally, among these steps, a card is put in a can and conveyed as a carrier medium of a sliver between the card step and the roving step. FIG. 18 shows a conventionally known can conveying system, in which (a) conveys the can 1 by placing the can 1 on a convey roller 201 which is not driven or is driven, and (b) shows a convey belt 202. The can 1 is placed on the can and conveyed, and (c) shows the can hooked by the can hook hook 203 so that the rear edge of the can is hooked and conveyed. Further, as shown in FIG. 19, the can 1 discharged from the combing machine 2a is gripped by the arm 205 of the robot 204 and rotated 180 degrees to rotate the belt 2
The form to put on 06 is also known.

[Problems to be Solved by the Invention] However, all of the conventional can transfer systems are in the form of transferring cans on the ground side, which is an obstacle when an operator walks. In addition, a floor space dedicated to the transfer machine is required, which causes an increase in the installation area of the entire spinning factory. Furthermore, when the can transportation equipment is used in the existing factory, the space between the spinning machines is small, and obstacles such as pillars of the building cannot be avoided, so that the can transportation path of the shortest distance cannot be secured.

The object of the present invention is made in view of the above problems,
An object of the present invention is to provide a can transportation system that does not require a space on the floor and can freely take a can transportation route with the shortest distance.

[Means for Solving the Problems] In the can transporting system of the present invention, a plurality of machine stands of the previous step of the two steps in the spinning factory are arranged along a general passage, and the front portion is separated by the general passage. In addition to arranging a plurality of machine stands and conveyors for supplying empty cans in the post-process that receives the actual cans from the process, the traveling truck that runs on the ceiling side is arranged along the above general passage, and this traveling route Two traveling carriages are pair-traveled in a pair, and one traveling carriage suspends a cage that is formed with an inlet for inserting an actual can on the front process side and an outlet for outputting an actual can on the rear process side so that it can be raised and lowered. On the traveling carriage, cages that have an inlet for inserting empty cans on the conveyor side and an outlet for outputting empty cans on the previous process side are hung so that they can be raised and lowered, and the actual or empty cans are stored in each cage and the cage is the machine base. Above the height of While moving up to the position, it runs between the machine and the conveyor that deliver the cans, and at the can delivery position, the cage descends to the ground position to land, and the cans delivered from the machine or the conveyor are placed in the cage. It is configured to receive the cans by pushing them into the machine base with pushers provided in the cage.

[Operation] Since the sliver can is housed in a cage and the cage is conveyed in the air so as to pass above the process, it is possible to avoid obstacles up and down and convey. Therefore, unlike the case where the can is transported on the ground side, there is no need for a space on the floor dedicated to the transport machine, and there is no hindrance when the operator walks. Such an effect becomes remarkable when the traveling path of the traveling vehicle is arranged so as to serve also as a general passage between machine bases or processes.
Further, the sliver is not compressed by the vibration during traveling, so that the thickness unevenness is prevented from being generated in the subsequent process.

In addition, while the runway of the traveling carriage is arranged between the spinning machine bases of the two steps, the cage is provided with entrances and exits for passing the cans on both side surfaces facing each other in both steps, so Cans can be taken in and out of the machine base, and even when traveling back and forth with the traveling carriage as a single track, the cans can be exchanged and there is no need to take up a large space between processes.

Further, since the cage is hung up and down freely on the traveling carriage and the cage is lowered to land on the can for handing the cans, it is not necessary to provide an elevating device on the ground at the delivery position of the process.

[Examples] Hereinafter, the present invention will be described based on illustrated examples.

(1) Example 1 FIG. 1 is an example of a can conveying system from the combing process to the kneading process.

As described above, the actual cage 11 is also provided with the pusher 31 and the stopper 61 having the same structure. 73 is a frame.

(B) Can transport between combing and kneading process Next, the operation of the traveling carriage in the can transporting system from the combing process to the kneading process will be described.

Returning to FIG. 1, the can 1 is delivered by the traveling carriage 7 between the combing process 2 and the drawing process 3 which are installed facing each other. Each machine stand of the combing process 2 and the drawing process 3 is divided into A, B, and C groups, and one empty can conveyor 5 belongs to each group. One of the traveling carriages 7 is in charge of one area of these A, B and C groups.

The functions of the traveling carriage 7 in the groups A, B, and C are the same, so the group A will be described here.

First, each traveling carriage 7 stands by above the delivery position P0 of the empty can conveyor 5 on the side of the drawing process 3, and this position P0 is set as the moving origin. At this movement origin P0, two empty cans 1a transferred from the empty can conveyor 5 are accommodated in the empty cage 12 of the traveling carriage 7, and the actual cage 11 does not accommodate the actual can 1b.

As shown in FIG. 11, the traveling carriage 7 moves to the side of the comb machine 2a of the group A which has output the full canning warning signal, for example, the comb machine "# 10". The carriage 7 stops the actual cage 11 above the comb machine "# 10" and lowers it. When the full can signal is output after the real cage 11 has landed, the operation of the comb machine 2a is stopped, and from the comb machine 2a, two full can cans 1b are placed in the real cage 11. It is pushed in at the same time. At this time, as shown in FIG. 3, when the actual cage 11 is landed, the engaging claws 22 formed on one side of the placing surface portion 21 and the engaging gears formed on the combing machine 2a in the combing step 2 The claws 24 and the claws 24 are engaged with each other in a wavy shape to form a groove 26 that is open upward. Therefore, the height error between the placement surface portion 21 of the actual cage 11 and the delivery position of the comber machine 2a is absorbed, and the actual can 1b delivered from the comber machine 2a can be smoothly delivered. Further, the actual can 1b taken into the actual cage 11 is positioned on a predetermined mounting surface by the stopper 61 provided on the outlet 17 side, and is prevented from coming off the actual cage 11.

The real cage 11 that has received two real cans 1b from the comber machine "# 10" moves up, and then the traveling carriage 7 moves by one pitch between the real cage 11 and the empty cage 12, and the comber machine "# 10".
An empty cage 12 is located in front of the empty cage 12 in place of the actual cage 11. An empty cage 12 descended, landed, and was housed in it 2.
Push out one empty can 1a with pusher 31 at the same time. If an abnormal load is applied to the pusher 31 that pushes out the empty can 1a, the ball bearings 45a to 45d shown in FIG. 6 slide axially on the guide rod 33 to absorb the occurrence of the abnormal load, Ensure safety. Sky Kens 1a comber machine “# 10”
The empty cage 12 pushed out and handed over rises.

Thus, the actual can 1b is received and the empty can 1a is delivered, and the delivery to the comb machine "# 10" is completed. In this way, in the combing process 2, the dispensed real can 1b is replaced with the empty can 1a in the empty cage 12. Then, the comb machine 2a receiving the empty can 1a restarts the operation.

The traveling carriage 7 for the group A, which has been handed over, moves to the kneading machine 3a in the drawing step 3 in the next step, for example, # 4, in which the request for the actual can is made in the group A.

As shown in FIG. 12, the traveling carriage 7 moved to the kneading machine # 4.
Lowers the real cage 12 accommodating the two real cans 1b to land it. Upon landing, the stopper 61 is retracted. In the actual cage 12, the pusher 31 pushes out the actual can 1b onto the delivery conveyor 3b. The actual can 1b is taken into the drawing machine 3a, while the actual cage 11 that has completed the delivery moves up and returns to the empty can conveyor 5 side, which is the moving origin P0 together with the empty cage 12.

As shown in FIG. 13, the empty cage 12 is lowered at the movement origin P0, and the empty cage 12 pushed out from the empty can conveyor 5 is positioned and accommodated in the stopper 61 by the stopper 61 in the empty cage 12 retracted from the pusher 31. . The empty cage 12 accommodating the empty can 1a rises, and waits at that position until the combing machine 2a outputs a full can warning signal. When the full can warning signal is received, the empty can 1a and the actual can 1b are delivered by the above procedure. That is, the empty can 1a of the empty can conveyor 5 is replaced with the actual can 1b produced in the combing process 2, the actual can 1b is conveyed to the next drawing process 3 and handed over, and then the empty can conveyor 5 is empty. The operation of receiving the can 1a is performed.

In this way, the traveling rail 6 is arranged on the ceiling side also for the general passage between the machine bases or the processes, and the cans 1 are hung by the cages 11 and 12 of the traveling carriage 7 suspended up and down. Can be transported in the air. In addition, it is possible to avoid the interfering object from side to side or up and down and convey it. Further, it can be applied to both single-track and double-track, and cans can be received and put in and out freely on all sides, and the traveling vehicle itself can be used with one unit, two units connected, a pair of two units, or a combination thereof.

(2) Example 2 In the above example, the delivery of the can 1 between the combing process and the filament process was described. However, as shown in FIG. 14, the cages 11, 1 are also similarly set between the card / commer preparation process, the comb / drawing process, and the drawing / roving process.
You can deliver Kens 1 by 2.

(A) System Configuration In FIG. 14, 81 is a card machine, 82 is a comber preparation machine including a sliver wrap machine and a ribbon wrap machine, 2a is a comber machine, and 3a is a first mixing I and a second continuous II. Is a roving machine, and 84 is a stock room for the roving machine. In FIG. 14, eight card machines 81, two combing machines 82, 14 combing machines 2a, and four kneading machines 3 each constituting one group are shown.
a Only five sets of rovings 83 and one stockroom 84 are shown, but as suggested for the rovings 83, other sets of sets connected to them are also on the left side of the figure.

Between the machine array for the card process and the two comber preparation machines 82, along the machine array for the card process, there is a transportation path 85 for waiting for transportation of the cans 9 that are in full operation and in process. An empty can conveyer 86 for stocking empty cans 9a is arranged on the ground side and extends in the direction of the comber 2a at a right angle from the right end of the transport path 85. Further, an empty can conveyor 5 extending in the same direction as the empty can conveyor 86 in the same direction as the empty can conveyor 86 over the kneading process and the roving process is arranged on the ground side. The size of the can 9 handled between the card process and the combing preparation process is different from that of the can 1 handled between the combing process and the kneading process, and the can 9 is larger.

On the other hand, on the ceiling side of the spinning factory, between the card machine 81 and the comber preparation machine 82, a runway 91 composed of the running rails 6 (Fig. 2) is arranged in a closed loop along the machine stand arrangement of the card process. It is installed, and the traveling carriage 10 is hung on it. This traveling carriage 10 has an actual cage 11 and an empty cage 12 like the traveling carriage 7 described above, but since the size of the can 9 to be handled is large, the actual cage 11 and the empty cage 12 have a can 9
Basically, it has the same configuration as the traveling carriage 7 except that each one is stored and is automatically transported.

Between the combing process and the kneading process, a runway 92 for the traveling carriage 7 used in FIG. 1 is arranged. However, this runway
Unlike in the case of FIG. 1, 92 is formed in a closed loop shape. In addition, a runway 93 for the traveling carriage 7 is also provided between the kneading process and the roving process. This runway 93 does not form a closed loop, it extends linearly from the end to the beginning of the frame arrangement of the kneading machine and the stock room for the roving process.
It is curved to the entrance of 84. Further, in the roving process as well, the runway 94 for the traveling carriage 7 is arranged in a closed loop. The runway 94 is surrounded by the empty can conveyor 5 for each unit, with one group consisting of the above-mentioned five rovings 83 and the stock room 84 as one unit, and the runway 94 for each unit is defined by a switch table 95. They can be connected to each other, so that the entire machine frame arrangement of the roving process consisting of multiple groups can be
It can be reconstructed into two closed loops.

(B) Can transportation during the card / commer preparation process In FIG. 14, the position of the empty can conveyor 86 with respect to the runway 91 is the origin position of the traveling carriage 10. First, the traveling carriage 10
Stand by at the origin position Q0 of the empty can conveyor 86, and at this moving origin Q0, the empty can conveyor 86 will empty the can to the empty cage 12.
Handed over one 9a. The traveling trolley 10 moves to the card machine 81 that has output the full can signal, for example, the “# 8” side, and stops the actual cage 11 above the full cans pick-up position (the position of the hatched circle). To lower this. When the real cage 11 is landed, one full can can 9b is pushed into the real cage 11 from the card machine "# 8". At this time, the actual can 9b is smoothly transferred due to the crossed engagement state of the inclined engaging claws 22 of the mounting surface portion 21 and the inclined engaging claws 24 of the cover machine 81 described in FIG. . Further, the actual can 9b is prevented from coming off the actual cage 11 by the stopper 61.

The real cage 11 that has received one real can 9b from the card machine "# 8" moves up, then the traveling carriage 10 moves slightly, and the empty can lowering position of the card machine "# 8" (the position of the white circle)
Before, the empty cage 12 is positioned. When the empty cage 12 descends and lands, the pusher 31 operates to push out the empty can 1a in the empty cage 12. After that, the empty cage 12 rises.

Thus, in the card process 81, the paid-out real can 9b and the empty can 9a are replaced.

The traveling carriage 10 that has completed the transfer moves toward the comber preparation step of the next step, stops at the full cans lowering position Q1 on the transport path 85, and disposes the actual cage 12 accommodating the actual cans 9b. Lower and land. The stopper 61 is retracted, and the pusher 31 moves the actual can 1b in the actual cage 12 to the transport path 85.
Pushed out. The actual cage 11 which has completed the delivery moves up and returns to the empty cage 12 with the empty cage 12 toward the empty can conveyor 85 which is the moving origin Q0.

16 pieces of the real cans 9b on the transport path 85 are set in each combing preparation machine 82 as one set. In FIG. 14, the actual can 9b in the process is shown by a white circle with an X mark. In each comber preparation machine 82, first, the sliver from this real can 9b
16 doubling with sliver wrap machine and 1.4 ~
Draft about 1.5 times to make a wrap, then wrap this wrap about 5.5 to 6.0 times with a ribbon wrapping machine and double the resulting fleece to finish it on the conveyor 87 as shown in Fig. 15. Produces wrap 88. The finishing wrap 88 on the conveyor 87 is the wrap transporter 89.
As a result, eight pieces of one comber machine are simultaneously pulled up from the conveyor 87 and conveyed in the air, and set on one comber machine 2a.

The combing machine 2a consists of 8 heads, the lap 88 supplied by each head is combed, and the obtained sliver is combined and drafted into 2 comb slivers. Paid.

(C) Can transport between combing and kneading process The runway 92 is the same as that already described with reference to FIG. 1, and the can is delivered in the following manner.

Normally, each traveling carriage 7 stands by above the position of the empty can conveyor 5 (moving origin P0), and two empty cans 1a are accommodated in the empty cage 12.

When the full boom warning signal is output from the combing process, the traveling vehicle 7 moves to the combing machine 2a that has output the warning signal as shown in FIG. 15, and dismounts the actual cage 11. When the full can signal is output, the two real cans 1b are pushed into the real cage 11 from the comb machine 2a. The real cage 11 that has received the real can 1b rises as shown on the left side of FIG. 15, and after the position of the traveling carriage 7 is corrected, the empty cage 12 descends as shown in FIG. The empty cans 1a are pushed out, and then the empty cage 12 rises.

Thus, the traveling carriage 7 which has completed the delivery to the combing machine 2a and has received the real can 1b moves along the runway 92 in the direction of the arrow 90, and the kneading machine on which the instruction to request the real can is made.
Move to 3a. When it comes to the position of the kneading machine 3a, the actual cage 12 containing the actual cans 1b is lowered to the full cans lowering position (the position of the circle with diagonal lines), and the actual cans 1b are transferred to the transfer conveyor 3b (the first). (Fig. 12).

The actual cage 11 that has been delivered to the combing process rises,
The traveling carriage 7 returns to the empty can conveyor 5 side, which is the movement origin P0. Then, the empty cage 12 is lowered at the moving origin P0, the empty cans 1a from the empty can conveyor 5 are accommodated, the empty cage 12 is moved up, and the comer machine 2a waits for the full can warning signal to be output again. .

(D) Can transportation between kneading and roving steps One kneading machine 3a is composed of two weights, and usually about ten kneading machines 3a are provided.
Unit 4 is composed of Unit 4. On the other hand, one roving machine 83 in the roving process comprises 120 spindles, and about 15 roving machines 83 are usually provided. In this embodiment, the first to fifth machines make up a group. .

Returning to FIG. 14, the traveling carriage 7 on the runway 93 between the kneading and roving processes
Is a configuration having only the real cage 11. Traveling trolley 7
Moves the actual can lowering position of stock room 84 Origin
R0 is configured to reciprocate between the origin position R0 and the actual can pick-up position of each kneading machine 3a (the position of the circle marked with diagonal lines).

When two real cans 1b are produced in one of the kneading machines 3a, the traveling carriage 7 moves to the kneading machine 3a, descends the real cage 11, and receives the two real cans 1b. After that, the actual cage 11 is lifted and transferred to the air to the actual can lowering position (moving origin R0) of the stock room 84 in the roving process. Then, the actual cage 11 accommodating the two actual cans 1b is lowered, and the two actual cans 1b are extruded from the actual cage 11 and delivered to the stock room 84 of the roving process.

Then, again, for the kneading machine 3a having produced two real cans 1b (the above-mentioned real cans 1m), the real cans 1b are picked up, and the cans 106 of the stock room 84 in the roving process are used.
Hand over to. By repeating this, the actual cans 1b are sequentially stored in the stock room 84 in the roving process. The actual cans 1b are sequentially transferred from the can conveyor 106 to the standby conveyor 107 in the stock room 84, and a total of 120 actual cans 1b are waited on the standby conveyor 107 in four rows of thirty.

(E) Stock room. Transferring cans between roving machines As mentioned above, one roving machine comprises 120 spindles. Therefore, when the cans currently set on the roving machine 83 become empty,
120 empty cans and Man cans must be exchanged at the same time. It takes 2-3 days for the cans set on the roving machine 83 to become empty, but once the cans become empty, 120 empty cans must be immediately replaced with actual cans. This is because productivity does not rise. However, since a normal roving machine usually has four stages and two stages at a time, it is possible to take a form in which 120 units are not exchanged at the same time. In the roving machine, about 15 winding bobbins (shino winding) are doffed (produced) in one can.

Therefore, the runway 94 for conveying the cans in the roving process comprises one group consisting of the above-mentioned five rovings 83 and the stock room 84.
As a unit, not only is it surrounded by a closed loop,
The switch table 95 and the intermediate connection path 110 can connect the running paths 94, 94 for each unit to each other.

As shown in FIG. 17A, the switch table 95 has a straight path 108 and a branch curved path 109, and one of them is moved so as to be located between the runway 94 and the intermediate connection path 110. This is a possible configuration. That is, in the case where the traveling trolleys 7 of each unit are connected to each other so that the traveling carriage 7 goes straight, FIG.
As described above, the straight road 108 is located between the runway 94 and the intermediate connecting path 110. Further, when the runways 94, 94 for each unit are separated to form a single runway 94, that is, when the traveling carriage 7 is curved, as shown in FIG.
Is located between the straight part of the runway 94 and the turn road.

In the case of this embodiment, the empty can conveyor 5 is also included in the closed loop of the runway 94 of one unit. The traveling carriages 7 are of a type having one cage each, and there is no distinction between actual cages and empty cages. In addition, the traveling carriages 7 are independent of each other and are not in a connected pair.

Now, assume that 120 cans are emptied in one roving machine 83 in the group A shown in the right side of FIG. 14, for example, No. 1 "1". In this case, the switch tables 95, 95 are simultaneously
The runways 94, 94 for each unit are connected to form a closed loop as a whole. As a result, all the traveling carriages 7 belonging to the track 94 for each unit move into the group A. When the traveling carriages 7 have all moved into the group A, the switch table
95, 95 are restored to their original state all at once, and the independent runway of Group A 9
Return to 4.

In parallel with the above operation, the exchange of the empty can and the actual can is started from the nearest traveling carriage 7.

As described in detail, when the doffing signal is output from the roving machine “1”, the traveling carriage 7 moves the real can 1b to the full cans picking position R1 of the standby conveyor 107 of the stock room 84 at the picking position R1.
With the individual pieces stored, move to the canning can lowering position R4 of the roving machine “1” and lower the canning can. On the other hand, the roving machine “1”
Empty cans that have been used in R2 at the transport position such as a conveyor
Have been transferred to the location. Then, the traveling carriage 7 takes in these two empty cans at the same time, lifts them up, moves to the empty can lowering position R3, lowers the empty cans there, and delivers the empty cans 1a onto the empty can conveyor 5. This sky can 1a
Is carried on the empty can conveyor 5 and is carried to the empty can pick-up position P0 on the runway 92 between the combing and kneading steps.

In this way, all the traveling carriages 7 are fully mobilized,
Receiving empty can 1a and actual can 1b for roving machine "1"
Of 120 empty cans 1a in a short time
And the real can 1b. Then, the roving machine "1" which has received 120 actual cans 1b restarts the operation.
Further, the switch table 95 is switched, and the traveling carriages 7 other than the group A return to the track 94 of the group to which they belong. In the roving machine, about 15 winding bobbins (shino winding) are dot-finged (produced) in one can.

[Effects of the Invention] In summary, according to the present invention, the following excellent effects are exhibited.

Since the sliver cans are hung by the cage of the traveling carriage and transported inside the factory, it is possible to transport the cans in the air, which was not done in the past. There is no need for a space above the floor dedicated to the transfer machine as in the case of transferring cans on the ground side, and obstacles can be left and right without increasing the installation area of the entire spinning factory.
It is possible to ensure the shortest can transportation path while avoiding up and down, and also to be used as a general path between machine bases or processes so as not to be an obstacle when the operator walks. Furthermore, the sliver is not compressed by the vibration during traveling, so that the thickness unevenness is prevented from occurring in the subsequent process.

Further, since the sliver cans themselves can be automatically and unmanned transferred, which has not been achieved in the past, an automatic connection between the processes is possible, which provides a basis for automating all the processes of the spinning mill.
