Description

DETAILED DESCRIPTION OF THE INVENTION In general, it is well known that in the fiber manufacturing process, a continuous fiber bundle is once stored in a can, and then a plurality of cans are put together and taken out from the can again for processing in the post-processing process. There are 3.

For example, in the spinning process of short fibers such as polyester and polyamide, the spinning speed is an order of magnitude higher than the post-processing speed such as drawing and cutting, so it is impossible to make the spinning process and post-processing process continuous, and once The method used is to store it in cans.

Conventionally, as a method for storing fiber bundles in a can, the fiber bundles are ejected with an air nozzle and placed on the can, and the nozzle is rotated around its axis, or the nozzle is swung back and forth and left and right.
Alternatively, there is a method in which the fiber bundle is dropped onto a fixed location and the table on which the can is placed is rotated and revolved, or moved back and forth and left and right to store the fibers in the can.

In any of the above methods, when the can becomes full, it must be replaced with an empty can.

During the exchange of cans, the fiber bundles continue to fall, so the fiber bundles are received in a tray while the fiber bundles are being replaced by empty cans, and then the tray is moved above the waste storage box. Then, the fiber bundles that are connected between the receiving tray and the can that has finished storing fiber bundles and the can that has started storing fiber bundles are cut by a cutting device installed between these cans and the waste storage box, and then placed in the receiving tray. An automatic method for disposing of fiber bundles is known in which the remaining fiber bundles are discharged into a waste storage box. However, in the above case, the fiber bundles remaining in the tray are discharged to the waste storage box, which increases the amount of waste and reduces the yield of the product.
When moving the tray above the waste storage box, the fiber bundles may be slippery because they are coated with oil, but the fiber bundles may be unnecessarily drawn out of the can due to their own weight and fall to the floor. Trouble is likely to occur.

The present inventors have conducted research on a fiber bundle processing operation that does not cause the above-mentioned troubles when automating the fiber bundle processing operation during the changeover from full cans to empty cans, and have arrived at the present invention.

That is, when the present invention replaces a can that has finished storing fiber bundles with five empty cans, a sorting head having a sorting plate swingably held on both can sides is positioned above the gap between the two cans, While holding that position, it moves in synchronization with the replacement of both cans, and by the fiber bundles falling onto the distribution plate, the distribution plate is tilted from the can side where the fiber bundles have been stored to the empty can side to bundle the fibers. It is characterized by switching the supply to the empty can side, then cutting the fiber bundle supported by the sorting head by a cutter built into the head, and then returning the sorting head to the standby position. do. This method consists of a distribution plate that is swingable between a can that has finished storing fiber bundles and an empty can that will replace the can, and a cutter that cuts the fiber bundle that has been passed from the can that has finished storing fiber bundles to the empty can. Sorting head with
The head is provided with a delivery device that moves the head in synchronization with the replacement of both cans while positioning the head above the gap between the can in which the fiber bundle has been stored and the empty can, and returns the head after cutting the fiber bundle supported by the head. This can be done by doing something to j to return it to its position. Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is a fiber bundle, and the fiber bundle is made by converging yarns spun from several to several dozen spinning heads through each guide, and then passing through a capstan roller, a gear nip roller, and a machine sector (Figure 1). (not shown), and is stored in a can 3 placed under the duct 2.

The can 3 is traversed back and forth and left and right by a chain conveyor 4 that traverses in the A-B direction, and a cart 5 that traverses in the C-D direction perpendicular to the conveyor 4, and the fiber bundle 1 is locally stored. It is now possible to prevent When a predetermined amount of fiber bundle 1 is stored in the can 3 in this way, the can 3 is returned to a predetermined position, such as the center, directly under the duct 2, and then replaced with a waiting empty can 3a. Ru.

There have been many proposals for braking such cans. For example, an automatic counter (not shown), which sets the fiber bundle length from the rotational speed of a capstan roller, provides a signal indicating that a predetermined length of fiber bundle has been supplied. When the (full can signal) is issued, the chain conveyor 4 and the trolley 5 return to their normal positions (initial positions), and then a timer (not shown) controlling the conveyor receives the groove can signal issued by the auto counter. This can be implemented by assembling a sequence circuit so that the chain conveyor 4 rotates in the direction of arrow B for a predetermined time when the time is up.

A guide rail 17 for transporting the sorting heads 6 is provided parallel to the chain conveyor 4.

As shown in FIGS. 2 and 3, the main body 6a of the sorting head 6 has a concave shape when viewed from the front, and is provided with skirt portions 6b at the front and rear thereof.

Reference numeral 7 designates a cutter portion, and 10 represents a cylinder built into the head body. Usually, a cylinder rod 9 protrudes to close the entrance of a U-shaped groove 8 in the cutter portion 7.

Furthermore, a cutter 11 made of an electric heater is fixedly installed below the cylinder rod 9 facing the cutter part 7.
The cylinder 10 and the cutter 11 are energized to the cutter 11 when, for example, an auto-counter full signal is issued so as not to lose their operating timing.The cylinder 10 also has an auto-counter and a timer for controlling the cutter cylinder. It is made to operate when the fiber bundle 1 comes to be stored in the empty can replaced by the full can.

Further, on the shoulder 12 at the tip of the head body, there is provided a tongue-like distribution plate 13 whose width gradually decreases toward the tip, so that the distribution plate 13 can be swung laterally with respect to the longitudinal direction of the head body. It is provided so as to be swingable in the direction of the can 3a in which the fiber bundle has been stored and the empty can 3.

At this time, the distribution plate 13 is preferably installed so that its tip faces the cutter portion 7, and its width is set to be sufficiently large considering the gap between full and empty cans when changing cans. on the other hand,
A shoulder 14 on the root side of the head body slopes downward toward the cutter part 7. 13a also connects the front edge of the distribution plate to 13b
indicates the trailing edge.

The head 6 is attached via a connecting rod 15 to a slider 16 that is loosely engaged with the guide rail 17 so as to be perpendicular to the guide rail 17. The guide rail 17 has both ends 17
a, 17b are slightly sloped downward and are supported by lifting cylinders 18, 20. The elevating cylinder 18 is longer than the other elevating cylinder 20, and when these shafts 19 and 21 rise, the guide rail 17
so that it has a downward slope toward the insertion side of the empty can. At this time, a head having a shape in which the skirt portion 6b of the head is removed may be used so that the end of the fused fiber bundle hangs outside the can.

At this time, the height at which the guide rail 17 is lifted is sufficient as long as the lower end of the hanging rod 22 attached to the head body 6a exceeds the upper edge of the empty can 3a.

Further, the length of the hanging rod 22 is sufficient so that its lower end is located below the upper edge of the empty can 3a when the guide rail 17 is held at the normal position. Reference numeral 23 denotes a rotation prevention rod for preventing rotation of the slider, and a wheel 24 is provided near the lower end of the rod.

Reference numeral 25 denotes a guide plate on which the wheel 24 rolls, and its width must be sufficient to prevent the wheel 24 from derailing when the guide rail 17 moves up and down.

The guide plate 25 and the lifting cylinders 18, 20 are fixed to a support column 26, and the support column 26 is fixed to a plate 27 attached to the truck 5.

28 is a roller conveyor on the empty can supply side, and 29 is a roller conveyor on the can discharge side.

At this time, the head 6 is adjusted and attached to the connecting rod 15 so that the distribution plate 13 passes directly under the duct 2 when the empty can is transported.

Hereinafter, the operating state of the device of the present invention will be explained. When the auto counter that measures the amount of fiber bundles 1 supplied from the start of storage detects that the can 3 storing the fiber bundles is full, the chain conveyor 4 is stopped by a signal from the auto counter.
The cart 5 supporting the chain conveyor returns to its initial position at the time when fiber bundle storage was started.

At the same time, the roller conveyor 28 below the empty can 3a on standby rotates, and the empty can 3a is pushed onto the chain conveyor and approaches the can 3 that has finished storing fibers. At this time, the hanging rod 22 of the sorting head 6 hits the edge of the empty can 3a, and the sorting head 6 is drawn out from the standby position by the empty can 3a. This state is shown in FIG. Next, when the timer for controlling the conveyor times out and the chain conveyor 4 rotates in the direction of arrow B and the full cans 3 and empty cans 3a begin to be replaced, the sorting head 6 moves between the full cans 3 and the empty cans 3a. It is transported by the empty can 3a while maintaining its position above the gap.

Eventually, the fiber bundle 1 comes into contact with the distribution plate 13 as shown in FIG.
3 switches to the empty can 3a, and the fiber bundle 1 is promptly thrown into the empty can 3a.At the same time, the fiber bundle 1 slides on the front edge 13a of the distribution plate 13, and the tangles and lumps are sorted out, and the fiber bundle 1 is almost elongated. In this state, it is guided 9 to the cutter section 7 and supported by the cylinder rod 9 (FIG. 8). The surface of the cylinder rod 9 is easily slippery, and the separation of the fiber bundle is facilitated. Furthermore, when the chain conveyor 4 rotates and reaches a predetermined location of the empty can 3a, for example, the center, directly below the duct 2, the chain conveyor 4 temporarily stops, the cylinder 10 is activated, and the cylinder rod 9 pulls in the fibers. When the bundle 1 falls onto the cutter 11, it touches the cutter 11, which is already energized and heated, and is fused, and its ends slide on the skirt portion 6b of the head and are stored in the respective cans 3 and 3a. .

After cutting the fiber bundle 1, the can 3 is transferred to a roller conveyor 29 on the delivery side.
Paid out by.

At the same time, chain conveyor 4 A-B
can 3a due to the movement in the C-D direction and the movement of the trolley 5 in the C-D direction.
swings back and forth, left and right, and the fiber bundle 1 is housed uniformly and without unevenness.

After that, when the truck 5 moves toward the D direction, the lifting cylinder 1
8 and 20 operate and the guide rail rises, the head 6
is guided by the guide rail 17 and automatically returned to the empty can insertion side.

When the head 6 returns, the front edge 13 of the distribution plate is placed along its path.
It is convenient to provide a projection (not shown) that can be touched by a to automatically change the orientation of the distribution board. In the above explanation, the case where the sorting head 6 is moved by the empty can 3a as a means for sending out the head has been explained, but the present invention is not limited to this. For example, the empty can can be moved by a piston or a chain belt. It is possible to adopt a method in which the container is moved in synchronization with the movement of the container, or a method in which it is pulled by a full can.

Furthermore, the cutter section 7 is not limited to the structure described above, and may be designed in any desired manner.

for example,. As shown in FIG. 3, it is also possible to provide a push-cut cutter 11a that faces the concave groove 8 and opens and closes the groove. Furthermore, the return means for the head is not limited to the above-mentioned ones, and for example, a piston,
Alternatively, it is possible to employ a means for returning to the original state using a chain belt or the like.

As described above, according to the present invention, not only is the fiber bundle 1 quickly switched from a can that has finished storing fibers to an empty can by the distribution plate, but also that the fiber bundle 1 is The tangles and clumps are removed, and the cutter section 7
Even if the fiber bundle is introduced into the machine, it does not immediately touch the cutter 11 (11a), and is once supported by the cylinder rod 9 or the groove 8 of the cutter part, so that the tangles of the fiber bundle are removed there as well, and the fiber bundle is in an elongated state. The result is a complete cut without any miscuts.

Moreover, the fiber bundle 1 supplied from the duct 2 is distributed to the distribution plate 1.
3, the fibers are sorted from the cans 3 that have finished storing them to the empty cans 3a, so they are stored in the cans 3a without waste, and the product yield is greatly improved compared to conventional equipment. It also prevents contamination due to falling off.
