The present invention relates to a method of circulating a can between a spinning device and a stretching device during a process of manufacturing a synthetic fiber soup.

In a conventional spinning apparatus, a plurality of discharge yarns (for example, about 20) are collected and capped by a capstan roller of a focused yarn. And a pair of nip reels are transported to the cans by interposing an inlet of a shoot or ejector that is fixed or oscillated. A cans (hereinafter referred to as full tube cans) carrying a focused thread of a constant length or a certain weight are sequentially transported to a predetermined storage place by a truck driven by a worker. And a predetermined number (5-40) of full tube cans are transported one by one from the storage area to the creel of the drawing device, and are drawn out to the creel section by individual focusing yarns. Then they are stretched together.

Here, the radiation take-off is 300-2,000m / min in hunger condition such as 2 -2 million De, while the stretching treatment is 50-300m / min to collect 50-300m / min. Do it at low speed. Therefore, the difference between the time from the start of storing the focusing thread to the empty cans and the time from the completion of the drawing process by drawing out the focusing thread from the full pipe cans to the air pipes It is roughly determined according to the difference in processing speed mentioned above. When the drawing process is completed and the cans are made to the mission, all the blank cans are taken out from the creal part to the empty cans storage place one by one by the vehicle, and then the required number of full tube cans are transported from the above-mentioned storage place to the creal part to be extended again. Is performed. Meanwhile, the bincans, which are transferred to the bincans storage area, are sequentially transported to the head of the focusing team.

The problem with the conventional circulation system between the spinning device and the stretching device is that a large amount of manpower is required for the replacement job of the cans in the crease part (the operation of taking out the empty cans and subsequently bringing in the full tube cans). Even if it is necessary to concentrate, and even if manpower is concentrated, the replacement work time of the cans is relatively long (about 1 hour), the operation rate of the stretching apparatus is decreased, the transfer efficiency of the cans is poor, and the cans wait unnecessarily. The result is a very large space inside the room where the cans operate. In particular, such a problem becomes remarkable when a large capacity ratio (a large number of lengths of the size of a connected thread of a case becomes large) is implemented.

In view of such a problem, the present invention provides a method of transporting the cans well and improving the operation rate of the stretching treatment, and also capable of reducing the manpower and energy and increasing the capacity. That is, according to the present invention, a spinning device for storing yarns focused on a plurality of emission yarns is placed in a cans, and a device for drawing out the focused yarns from a predetermined number of cans through an upper creel and focusing them again and again. In the method of circulating the cans, a path through the palmar part of the focused yarn and a pair of parallel straight paths branching out from the path into the crease and extending below the core part are installed at the bottom and are separated from the branch position of the path. It is conveyed to the storage unit through the empty cans on the closed road leading to the storage area, and collects the focusing thread. Only the predetermined number is brought in on the other open road Cans due to the new end seuneun a radiation stretching method for synthetic fiber tow comprising a step that is taken out from the closed to the open-circuit prior to transfer of mangwan kaenseu reached by palmar through the branch location.

Here, Gaero means that Lo became unable to go further.

An example of an apparatus for implementing the present invention will now be described with reference to FIGS. 1 and 3.

As shown in FIG. 1, the radiator installed on the second floor discharges the polymer from a nozzle having a plurality of holes (not shown), and cools it in the cooling radiator 1 to steer it to deflect the roller. Sends dozens of threads to the focusing guide 3 through 2, draws them out to the capstan roller 4, and guides them through the guide roller 5 to the nip reel 6 with teeth on the main surface. It is to be grabbed and sent out. The focusing yarn Y, which is continuously sent out from the naprail 6, is stored at a speed of 1,000 m / min in the cans 8 through the normal inlet 7 installed on the first floor with a thickness of 360,000 De.

In the present embodiment, the ejector or the like is used in the inlet 7 to perform the oscillation movement in the left and right, and in the front and rear (refer to the front and back direction of the ground). The cube-shaped case 8 (weight of about 0.15 tons) of 2.0m × 2.0m × 2.0m is stopped below the inlet 7, but as a means of storing the focusing thread Y in the case 8 via the inlet 7, For example, the inlet 7 may be a fixed chute, and a can traverse system in which the can 8 traverses from side to side and back and forth can be used. When the specified amount of focusing thread V is stored in KS 8, it is exchanged for an empty KS.

Moreover, it takes about 60 minutes for the cans to be fully filled, which is called canopy time.

As shown in Fig. 2, the transverse drawing apparatus, which stores the focusing thread Y under the inlet 7 and has a quantitative amount (approximately 2 tons in weight), as shown in FIG. It is installed above the front 22 and is transported down the creel 18 extending in the same direction as the longitudinal direction of the stretching apparatus.

Here, only 12 predetermined full canals 8 are fixed. The focusing thread Y drawn from the corner tube can 8 is lifted to the creel 18 and travels at a speed of about 50 m / min horizontally on the guide rods 19 and 20 with the guide pin upright, and the guide stand 21 (each focus). Enter the drawing device 22 through the hole through which there are a number of holes through which yarn can pass.

) Guide (not shown) 3-6 feeds with a focusing thread through 1 or several target tow via an oiling bath 23, a tensioner (not shown) The undrawn tow (43.2 million De) is stretched and heat-treated at about four times at a drawing speed of 200 m / min by a steam bath or hot water bath, a drawing roller, a drying roller (not shown above), or the like.

The stretching apparatus 22 is provided with the above-mentioned elements symmetrically on both sides of the block 25 which accommodates the drive source main irrigation system, but FIG. 2 shows only one side element. For one side of drawing device 22, cans 8 are arranged in two rows below cline 18, with one row being the processing line and the other row being the standby line. That is, while the focused yarn from the cans of the processing line is subjected to the stretching process, only a predetermined number of full tube cans are sent to the waiting line one by one. When the cans in the processing line become empty, the focused yarn is drawn out from the cans in the waiting line (and thus, the processing line and the waiting line are exchanged), and the empty blanks remaining in the new waiting line are taken out one by one to take out all empty cans After this is completed, the filling cans are sent to this waiting line as before.

In addition, it takes about 20 hours if there is no failure in the stretching device and the next process until each scan of the processing line becomes empty, but it takes 22-23 hours because it is actually wound around the rollers and failure occurs due to poor crimping. .

The cans circulation device between the above-described processing and waiting line below the creil and the storage portion directly below the inlet is described in detail with reference to FIGS. 1 and 3.

At the bottom of the first floor, a straight tube feed path a _{1 which} extends from the lower part of the inlet 7 to the drawing device 22, a straight can feed path a ₂ connected to the end of the tube pipe supply path a _{1, and} an end thereof is a with a _2, a blank kaenseu waiting in a line connected to a _3, a blank kaenseu transported on the straight line connecting the end of a ₃ to atmosphere a _4, and the ends are connected to the empty kaenseu a ₄ to transfer also the supply mangwan kaenseu a Chill as one end is connected to the bincan supply path a ₅ leading to ₁ , the canal feed path a ₂ , and the other end is located below the core of the crease 18 (the side close to the stretching device 22). Straight openings B ₁ , B ₂ , C ₁ , C ₂ extending in parallel to each other and parallel to each other (as described above, B ₁ and B ₂ and C ₁ and C ₂ are alternately the cross-line process and is the standby line) and the end portion is connected to a middle part ₂ to the transfer kaenseu Has as a spare line is D _1, D ₂ are installed in a spherical (溝狀). The furnace a ₁ , a ₂ , a ₃ , a ₄ , and a ₅ form a lung furnace A according to the present invention. Moreover, the connection of the angles is at right angles, but to facilitate the exchange of the cans.

정도(50-90%가 바람직한 범위이다)로 형성되어 있으나 이것은 캔스 8을 이들의 로상(路上)에 정치하는데 알맞기 때문이다.The groove widths of the roads a ₁ , a ₃ , a ₅ , B ₁ , B ₂ , C ₁ , C ₂ , and D extending in the same direction as the length of the creel 18 are all the widths of the cans 8.

It is formed to a degree (50-90% is a preferable range), because it is suitable for placing the Kance 8 on their furnace.

On the other hand, the a ₂ and a ₄ groove widths extending perpendicular to the longitudinal direction of Crail 18 are 10-50% larger than the width of KS 8 in order to allow stable and easy exchange of the KS between other furnaces. Formed.

In the above-mentioned canal conveyance path, the pipes plying supply path a ₁ empty canned atmosphere a ₃ empty cans supply path a ₅ are provided with positions p ₁ , p ₂ , and p ₃ , respectively.

On the other hand, as a transportation device for moving in the canister conveying path, it is installed to reciprocate the three blocks of the positions p ₁ , p ₂ , p ₂ , p ₃ and p ₃ p ₁ to exchange the cans, but as shown in FIG. The transport device 10 between the positions p ₃ and p ₁ is independently of each other by an attached lifting motor (not shown) on the traveling body 10b having the wheel 10a driven thereon by an attached driving motor (not shown). It uses the two cargo bases 10c and 10d which can be elevated. On the other hand, the conveying devices 11 and 12 between the positions p ₁ and p _{2 and} between the positions p ₂ and p ₃ are driven by an attached driving motor (not shown), and the wheels 11a are stopped by brakes (not shown). The lower part is provided with the wheel 11c, 12c which is driven by the main driving bodies 11b and 12b which have 12a in the lower part, and the wheel 11c and 12c which stop by a brake (not shown) by the attached driving motor (not shown), The sub-cars 11e and 12e are provided with cargo carriers 11d and 12d on the upper side, which can be lifted and lifted by a motor (not shown). It is mounted on the upper rail (not shown). These transport devices 10, 11 and 12 are designed to travel on rails 13 (part of which are shown in FIG. 2 but most of which are not shown) attached to each furnace. Furthermore, each conveying apparatus is provided with a winding body (not shown) of a rod connected to a fixed portion in the lines a ₁ , a ₂ , and a ₃ for sending power control signals for each motor.

The conveyance of the cans due to these conveying devices is performed as follows.

The conveying device 12 normally waits at the standby position S ₁₂ (connected position with a ₃ for the empty scan waiting path) defined on the empty can transport path a ₄ , but the sub-drive 12e of the transport device 12 is empty from the main vehicle 12b. stops to enter therein in which out over a ₃ to atmosphere lowering the freight cradle 12d below of what is at the nearest position to the atmosphere in a ₃ atmosphere of empty kaenseu above position S ₁₂ state (as represented for the 1a turning this state) Then lift the cargo tray 12d to lift the empty can slightly off the floor. (Claim 1c gives the status) is hayeoseo maintain state careless haengche 12e is running a a ₃ above to an empty kaenseu atmosphere and is ridden up over the shareholders haengche 12b of the carrier 12 that may be waiting in the waiting position S _12. Following carrier 12 travels up the feed path a ₄ and comes to a stop with the emptycan supply feed path a ₅ .

The subchance 12e with the emptycane placed on the cargo stand 12d exits from the main vehicle 12b above the supply path a ₅ (Figure 1 indicates this case) and stops at the position p ₃ where the cans are exchanged.

The cargo tray 12d is lowered to stop the empty can on the bottom surface as indicated by the dotted line in FIG. After that, the subordinate vehicle 12e travels backwards to the present time, and climbs onto the main vehicle 12b, and goes to get the next empty can in a timely manner.

Before the focused yarn Y enters a certain amount into the can 8, the conveying apparatus 10 goes to have an empty can set at the position p _{3 which} is exchanged as described above. In this case, the transport device 10 stops when the cargo tray 10c near the transport path a ₄ enters the inside of the bottom of the empty cans while the two cargo trays 10c and 10d are lowered. It stays in this state and travels in the downward direction of the inlet 7 and stops when the other cargo base 10d enters the bottom of the can 8 during the storage (Figure 1 shows the state).

And running only slightly up towards a ₁ above to mangwan kaenseu transfer afloat the mangwan kaenseu 8 by raising the cargo base 10d from the bottom surface when the converging yarns Y are collections certain amount within kaenseu of the head 8 at a position p ₁ to send and receive kaenseu and Once the center of the empty can stops at the position below the inlet 7, the cargo tray 10c is lowered to stop the empty can on the bottom, and then drive again. When the KS 8 arrives at the position P _1, it stops and lowers the cargo tray 10d. The standby position S ₁₀ defined between the positions P ₁ and P ₃ , for example, as shown in FIG. Allow it to return and wait until the next cancel change.

The drawer 22 is now processing the drawer withdrawal from the cans stationed on B ₂ and C ₂ with dogs, and the 12 bin cans are processed on B ₁ with dogs and no cans on C ₁ with dogs. As described above, a case in which a full tube can be sent to the position p ₁ is exchanged to C ₁ in turn, and only a predetermined 12 are brought in.

Carrier 11 when the air typically is in the standby position S ₁₁ (mangwan kaenseu connection with a ₂ to a feed position) binary appointed over a ₄ to kaenseu transfer and although the value at a position p ₁ to and Suga mangwan the can of which inadvertent haengche 11e Enter and stop with the cargo stand 11d lowered, raise the cargo stand 11d, lift the crown tube from the bottom, and climb onto the main driving system 11b. (Fig. 1 shows this state.) And the conveying device 11 travels on the canal transport path and stops at the opening position with the opening C ₁ . Here careless haengche 11d is stopped when from the main driving dog comes up positions C ₁ pieces doeyeo progress toward the inside of the above C ₁ kaenseu first storage area hayeoteul mangwan can Suga position in Q _1. Wherein the cargo base 11d is lowered mangwan can seuneun it is to stand in a storage location Q ₁ first kaenseu. And the traveling body portion 11e is higher than the top of the dog sat on the shareholders, and stops driving the C _1, reverse haengche (and FIG. 2 L shows this state). The transport ₁₁ then returns to the standby position S ₁₁ . In the same manner, the full tube cans on the feed passage a ₁ are sequentially transferred to the _{second and twelfth} place of storage Q ₂ -Q ₁₂ on C ₁ .

This import takes about 12 hours.

In addition, the conveying device 11 stops at the connection position with the opening B ₁ by traveling on the conveying path a ₂ from the stand-by position 11 in order to transfer the empty can over the opening B ₁ by using the conveying interval of the full tube can. 11e to the open-circuit went to pick up (the closer to a ₂ to transfer), and then travel back again empty kaenseu above, B ₁ is stopped at the connecting position with a ₃ to empty kaenseu atmosphere.

The careless haengche 11e come up front what to run out into the atmosphere blank kaenseu in a witty status over a ₃ closest to a ₂ to the transfer of a ₃ blank kaenseu politics over into the atmosphere goes back with a witty empty kaenseu. The conveying device 11 then returns to the contact point B ₁ with the opening above the canal conveyance a _{2 and} transfers the next empty can on the opening B ₁ to the atmosphere a ₃ as before. Hereinafter, this is repeated to dispense all empty cans from above B ₁ . In addition, the transport units 11 and 12 are used to clean the empty cans on a ₃ as empty canned atmospheres. If the empty cans are reduced to a predetermined number (e.g., called six) between the ps exchange position p ₂ and the standby position S _{12 of} the transportation device 12, the transportation device 12 is moved to the pance exchange location p ₃ After the transfer, the sub-driving body 12e reciprocates over a ₃ to the atmosphere, and transfers only six empty cans one by one to the position close to the waiting position S ₁₂ .

Then transported to a careless haengche 11e of the delivery device 11 waits a ₃ to give exchanging a blank kaenseu political closest to the receiving position p ₂ p ₂ position above and return to pick up the next blank kaenseu. At this time, the empty cans fixed at the position p ₂ which the sub-driving body 12e exchanges are moved to the standby position S ₁₂ by traveling for five empty cans to the position immediately after the six empty cans that have been transferred.

Hereinafter, only 12 empty blanks are settled between the positions p ₂ and the standby positions S _{12 which} are exchanged repeatedly. By it, and then send and receive position p ₂ and to the atmosphere in the transfer of a ₃ cans remaining between the connecting position with a ₂ seuneun position to and by careless haengche 11e p 1 each move towards the _second it is to stand closer to the front.

When the carrying out of the predetermined number of full pipe cans over C ₁ is completed, the following is carried out in the same way as for the full pipe cans above B ₁ .

)되었을 경우 전후하여 감겨진 량의 차(반캔스 또는 테니어가 부족된 반캔스)가 가끔 발생한다.However, if the radiator does not break down, it takes about 24 hours to make 24 full tube cans, but it takes about 22-23 hours by winding the draw roller and replacing the spinning nozzle. Therefore, the operating capability of spinning process and drawing revolution is substantially balanced, but if the focusing thread is wound around the take-off roller or one strand of the emitting thread is

), The amount of rolled up and down (half-cancel or half-canal lacking tenor) sometimes occurs.

Therefore, in this embodiment, D ₁ is provided as a preliminary place to put these cans to be classified. The cans are transferred to D ₁ preliminarily by conveyers 10 and 11. The cans placed in D ₁ are preliminarily numbered, and when the stretching process is stopped (for example, when the spinning process is stopped for a long time), the batters are treated together.

On the contrary, when the stretching process does not have a big problem or a failure of the spinning process, there may be one to several full-length cans per day. As a result, in the present embodiment, these remaining full tube cans are preliminarily transferred to D ₂ by the transport apparatuses 10 and 11 so that any of the openings B ₁ , B ₂ , C ₁ , and C ₂ is preferentially open to the openings. It is brought in.

While one embodiment of the present invention has been described, sequence control is used to control a motor used for lifting and lowering the cargo stopper of each transport device.

Therefore the positions p ₁ , p ₂ , p ₃ , S ₁₁ , S ₁₂ and into a ₁ and into a ₂ of into B ₁ , B ₂ , C ₁ , C ₂ , D ₁ , D ₂ into a ₄ and into At each connection position of a ₅ , detecting the arrival of each traveling body is to detect the presence of as many cancels as necessary in the furnace and at a ₃ , B ₁ , B ₂ , C ₁ , C ₂ , D ₁ , and D _2. It is installed around the furnace, respectively. These detection means are sent to the Seikens control panel together with the single yarn detector of the radiator, the detector detector, the head length of the focusing yarn, the measuring device and the like. The signal from such a control panel is given to each conveying apparatus through the above-mentioned code, and controls conveyance of the above-mentioned case.

Moreover, in the embodiment, D ₂ is used as a preliminary furnace to keep the remaining tube pipe canned, but this may use a portion of the tube tube supply path a ₁ (between positions p ₁ and S ₁₁ ) as a temporary storage place. In this case, the cans to be classified cannot be immediately brought into D ₁ immediately, and thus a means for determining the cans is needed.

In addition, the transport devices 10, 11 and 12 are intended to cover only p ₂ and p ₃ between p ₁ and p ₂ between watches p ₃ and p ₁ which are sent and received from the lungs, respectively, but include positions p ₁ , p ₂ and p ₃ , respectively. Only appropriate sections may be allowed to overlap.

For example, inadvertent haengche 12e of the carrier 12 is in the empty kaenseu clean up easily when it to advance from the position p ₂ a ₃ above to the atmosphere until it biased on a ₂ at the feed kaenseu 12 minutes.

Next, another embodiment of the present invention will be described with reference to FIG. This is a circulator of the cans applied to the simultaneous storage of 200,000De focused fodder tanks, which are supplied at a speed of 1,000m / min, at the same time, so that each water pipe time is 110 minutes. Each tonnage treatment line is lined with fourteen canned lines and stretched 4.2 times at a speed of 330 m / min.

The stretching time is theoretically 23 hours but actually 25 to 26 hours.

In this circular seam, the furnace a ₂ , a ₃ , a ₄ and the bincane supply passage a _{6 in} addition to the same furnace closed as those of the furnace a ₁ , a ₂ , a ₃ , a ₄ indicated in the first embodiment. mangwan kaenseu to supply a _7, a _8, are provided in the closed circuit ₉ a. The furnace a ₆ , a ₇ , a ₈ has the same structure as the above-described furnace a ₁ , a ₃ , a ₅ and the like, and also has the structure of the furnace a ₈ degree with a ₂ , a ₄ . In addition to a ₂ hayeoteul it is only just extend a ₂ in the embodiment of the first. Rows a ₆ and a ₇ communicate directly underneath the second inlet 7 ′ and are the same as those of furnace a ₁ and a ₅ communicate underneath the first inlet 7. For a ₆ , a ₇ , and a _9, there are positions p ₄ , p ₅ , and p ₆ , respectively. And from the driving position to give a ₇ p ₅ in the receiving with a ₆ to and from the receiving location, and p ₄ of a transport device for the exchange of kaenseu is used it is identical to the carrier 10 described in the first embodiment. The same conveying device as the conveying device 12 described in the first embodiment is used as the conveying device for conveying the full tube can be transferred from the positions p ₅ to p ₆ . And for transferring to an empty kaenseu position to exchange the empty kaenseu of a ₃ p ₄ to the atmosphere above the handle and the carrier 12 itself shown in FIG. 1 for transfer to the position p _3.

Is also a mangwan kaenseu from position p ₆ to and open-circuit _{B 1, B 2, C 1} , the carrier 11 itself shown in FIG. 1 for transferring from the position p ₁ to and is being conveyed to any of the C ₂ to handle.

Although two embodiments of the present invention have been described above, the position of sending and receiving the cans may be determined at the connection position of each path. This is, for example, in the embodiment shown in FIGS. 1 to 3, the conveying apparatus 10 drives all the roads a ₁ and a _5, and the conveying apparatuses 11 and 12 are sub-drives 11e and 12e (also attached thereto). Instead, run a ₁ , a ₄ and run B ₁ , B ₂ , C by using a stand fitted with the cans fixed so that the quadrilateral upper surface of the main driving body 11b, 12b is flush with the base surface. ₁ , C ₂ and preliminary D ₁ , D ₂ are installed and run the same as the sub-drive 11e removed, respectively, the transport device 10 and the sub-drive on the main tracks 11b, 12b, placed on the track receiving the return and also received This can be done by having the cans of the tracks rolled back.

In addition, a device for traversing with a can may be provided in a part of the closed path (for example, just below the inlet 7 of the embodiment). In addition, a communication path may be provided between the adjacent system decommissioning systems, and may be used for conveying a full tube and / or empty cans. In this way, when the processing capacity of the radiating device and the stretching device is different due to a failure, there is an advantage that can complement each other when the same product. This is for example possible because standing continuous with those of the adjacent series to a _2, a ₄ in FIG. 3 on both sides, respectively (in normal time, and store the cover which the lid).

The effect by the present invention is as follows.

The circulation of the cans is performed smoothly and efficiently, and at the same time, the focusing thread of the stretching treatment is quickly replaced. Therefore, the ability of the spinning device and the stretching device can be easily harmonized, and the overall operation rate, production capacity improvement, and manpower and energy saving can be achieved. In particular, when the capacity is increased, such an effect is very large.

In addition, the canisters placed on the crease section are straight lines extending in parallel with the creels. Safe operation can be performed from the drawing apparatus side through the opening without crossing the conveying path.

In the above description, the case where each traveling body travels in the groove provided on the bottom surface has been described, but the bottom surface or the stand may be driven.

That is, FIG. 5 is a schematic diagram showing an implementation state when the sub-driving body runs the bottom surface F ₀ or the main driving body runs in the groove, and FIG. 6 is a front sectional view of FIG.

In FIG. 5 and FIG. 6, an angle 8a is provided at the bottom of the can 8, and the can 8 can be placed on the bottom surface F ₀ by the angle 8a. The subordinate vehicles 11e and 12e can also be grooved underneath the cans 8 if they drive above the bottom surface F _{0. Each} cargo 8a of the cans 8 is separated from the bottom when the cargo base 11d or 12d lifts the bottom of the cans 8. This becomes possible.

The main driving bodies 11b and 12b carry the bottom surface F ₁ in the groove with the subordinate driving bodies 11e and 12e and the cans 8 loaded.

In this way, since the running surface of the sub-driving body can be the bottom surface, it is possible to drastically reduce the grooves installed in the bottom surface, so that people's traffic and work are better. In addition, When the side stand F ₁ provided on the bottom surface F ₀ to the bottom surface it may be running over the ground surface shareholder haengche.
