Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for obtaining a bundle of linear objects of a constant length from continuous linear objects.

Conventionally, bundles of linear materials such as hollow fiber reverse osmosis membranes, hollow fiber ultrafiltration membranes, hollow fiber artificial kidneys, synthetic tatami mats, brushes, etc. have been made using at least one continuous linear material of a certain length. It is made by cutting.

The method for obtaining the bundle of wires is to wind the continuously produced wires around a shrink frame, take out the cassette, make a bundle of thick circular wires, cut it to an appropriate length, and cut it into wires. A method for obtaining a bundle of linear objects, and a method for obtaining a bundle of linear objects by linearly drawing out continuously produced linear objects into appropriate lengths, cutting them, and accumulating them (Japanese Patent Application Laid-Open No. 57-171759 No.) is known.

In the former case, since the wires are wrapped around a shrink frame, the wires are bent at the corners of the frame, and when the bundle of circular wires is pulled out and cut, disturbances occur in the east direction of the wires. There's a problem.

In the latter, the operations of linearly pulling out, grasping, cutting, and stacking linear objects are performed in batches, and the speed depends on the drawing speed, so there is a problem that it is not suitable for increasing the speed.

In addition, in both cases, if a defect occurs in any part of a linear product that is continuously produced, even if the defect can be detected by some method, cutting and removing that part is a big problem because the work will have to be stopped. There was a problem.

For this reason, it is not possible to obtain a defect-free bundle from continuous linear objects containing defects, and it is inefficient to select only the linear objects with defects and remove them after forming the bundle by cutting them. Work was needed.

An object of the present invention is to provide a method and apparatus for obtaining a linear product of a certain length, which solves the above-mentioned problems.

The method of the present invention, which solves the above problems, cuts at least one continuous linear object to obtain a bundle of linear objects with a predetermined length. is inspected at any position, and the set section length with no defects is wound onto a non-defective track whose circumference is the same as the setting - section length or an integral multiple of the length, and only the set section length of the linear object that has at least a defect is placed on a non-defective track. The bundle of linear objects wound on the non-defective track and the non-defective track is transferred without cutting to the defective track that is close to the non-defective track and has substantially the same circumferential length and circumferential speed as the non-defective track. It is characterized by cutting at points to separate bundles of good and defective wire products.

Further, the apparatus of the present invention is an apparatus for cutting at least one continuous linear object to produce a bundle of linear objects having a predetermined length. A linear object defect detection means is installed at any position, and the settings are the same as the ward manager.
Alternatively, the winding means is installed at a certain distance from the defect detection means, and has a circumferential length that is an integer multiple and is equipped with a good track and a defective track separated by a separator, and the separator has a set section length and a winding means. A linear object transfer gate is provided for each length, and the linear object is moved at a constant speed in a non-defective track just before the winding means, and the linear object is moved at a constant speed in response to a defect signal from the defect detection means. A toranose means is provided for transferring only the head to the defective goods trunk and then returned to the trunk, a cutting means is provided for cutting the bundle of wires wound up by the winding means at the gate position, and a defect detection means and winding means are provided. The section head to which the detected defect belongs is determined based on the relationship between the distance to the winding means and the continuous winding speed, and when the section head reaches the winding means, at least one section length of the linear object is removed by the traverse means. It is characterized in that the defect detection means, the tiger/safe means, and the winding means are connected to the calculation means for giving an instruction to shift to a non-defective track.

In the present invention, when the number of wires wound on a non-defective track reaches a predetermined number, a plurality of winding means are arranged to automatically remove the wires. Continuous operation is possible by transferring the winding from the full tube side to the vehicle side and winding it up. The bundle of molten material on the winding means, which has become a full tube, is moved to the cutting means, and the wire material is cut at the transition point (gate position) by the cutting means and taken out.

Next, the present invention will be explained in detail with reference to the drawings.

1 and 2 show an outline of the method and apparatus of the present invention, in which the defect detection device #1, the traverse device 2, 3, the winding The winding devices 4 and 5 are arranged at a constant distance @L and L', and a defect signal indicating a defect in the linear object transmitted from the defect detection device 1 and the winding device 4 are arranged.
.

When the distance between the defect detection device 1 and the winding devices 4 and 5 is large, a support roll 7 for preventing deflection of the linear object is installed according to the distance.

Detection of defects in a running continuous linear object is performed using optical and electrical methods.

Next, the structures of the traverse devices 2 and 3 and the winding devices 4 and 5, which make it possible to distinguish between good and defective products from a running continuous linear object, will be described.

The traverse devices #2 and 3 operate to uniformly wind the wire material F on the non-defective track 9 of the winding device 4.5, which will be described later. track 1
It consists of an operation of shifting to 0 and returning. Although any means can be used to obtain these two operations, FIG. 4 shows an example of a mechanism using a combination of gears and cylinders.

The traveling linear object is positioned by a guide 15. The guide 15 is pressed by a nozzle 16 against a shaft 17 with a rack gear.

This pressing force must be sufficiently smaller than the force with which the cylinder 19 pushes out the guide 15. The guide 15 moves a certain distance 16 depending on the forward and reverse rotation of the pinion gear 18. This moving distance t6 corresponds to the non-defective track portion of the winding devices 4 and 5, which will be described later.
The operation to shift to 0 is to move the cylinder 19 a certain distance L7.
This can be achieved by going back and forth.

The winding devices 4 and 5 have a non-defective track 9, a defective track 10, and a separation body 11, as shown in Figures 3-A, 3-B, and 3-B.
, has a fall prevention body 12.13 for the linear object F. Separate body 1
1. At least one gate 14 is provided in the drop-off prevention body 12.13 so that the linear object can be transferred.

As for the arrangement of the winding device 4 and the winding device 5, it is desirable to arrange them symmetrically in a direction perpendicular to the running direction of the linear object, as shown in FIG. You can also.

The tension of the running continuous linear object F is determined by the ratio L'/W of the distance W of the moving linear object and the distance L' from the defect detection device 1 to the traverse devices 2 and 3. If you make it large enough, you can make it uniform. Moreover, the phenomenon of increase in the running speed of the linear object F that occurs when the linear object F is wound up by the winding device 495 is caused by increasing the running speed of the linear object F while keeping the tension of the traveling linear object F constant.
, 5, or by interposing a dancer roll between the distance L' (not shown).

Settings - The operation when the length is equal to the circumference of the good trunk 9 of the winding devices 4 and 5 is shown in Figures 5-A, 5-B, and 5-C.
This will be explained using figures.

As mentioned above, 5. Setting area length/-1+ t2 r A3
+ t4 p t5 has a length equal to the circumference of the non-defective track 9 and the defective track 1o. From the time when the gates 14 of the winding devices 4 and 5 come to the contact point between the running continuous linear object F and the non-defective track 9 (referred to as the J-L lower winding start point), the length of the winding unit 'I + t2 + t3... is determined.

Now, in Figure 5-A, the section length t of the running continuous linear object F is shown.
3 shows a state in which the defect detection device 1 detects the presence of a defect A. The position of the guide 15 of the traverse device 2 at this time is in the section t6 shown in FIG.

Next, consider a state in which the linear object F travels one length (one rotation of the winding device). Since the section length t1 is a good product, the guide 15 is on the non-defective track side at this point, and the section length t1 is wound onto the non-defective track 9 as shown in FIG. 5-B. Furthermore, linear object F
When the vehicle runs, the state shown in Fig. 5-C occurs. In this state, the positions of the winders 14 of the winding devices 4 and 5 are below the winding start point.

When the gate 14 reaches the winding start point, the guide 15 is pushed out by the cylinder 19 shown in FIG.
3 is transferred to the defective product track, and then the cylinder 19 is moved backward by the distance t7 at the time when the gate 14 of the winding device 4 comes to the winding start point, the guy F15 is pushed away by the spring 16 and the defect is Only the section head L3 that says this can be wound onto the defective product truck IO. Further, if the defect is near the set section length (the opening position in Fig. 4-C), the guide 15 is operated so as to wrap around the defective trunk 1o at two section lengths (t3 and !-<).

The timing at which the guides 15 of the traverse devices 2 and 3 start is determined by the aforementioned calculation bag #6.

FIG. 6 shows the shape of the bundle F' of the linear material wound up by the above operation. Figure 7-A is an enlarged view of the transition point.

The state in which the wire material F is wound up as shown in Fig. 7-B (i, a plurality of gates 14 of the winding devices 4 and 5 are provided, and the length of the wire material to be wound on the defective product track IOK is shortened. It is.

In this case, the setting 1 section length is not the circumference of the non-defective truck,
This is the distance between gates.

The winding method shown in FIG. 1 is a method of converging a plurality of traveling linear objects F and winding them while distinguishing between a good track 9 and a defective track loK linear objects F. In order to reduce the amount of wires wound on the defective product truck, a method is also available in which only the wires with defects are transferred to the defective product truck and wound from among the multiple moving linear products. Can be applied.

It can also be applied to a method in which good and defective tracks are arranged for each unit of a moving linear object, and a traverse device is arranged to carry out the above-described operation for each unit of linear object to wind it up.

As a next operation, when the winding device 4 in FIG.・Transfer from the traverse device 2 to the traverse device 3. By this operation, the traveling continuous linear material F is transferred from the full winding device 4 to the empty winding device 5.

When the transfer of the linear object is completed, the winding device 4 and the winding device 5
A cutting blade is inserted between the winding device 4 and the winding device 5 to cut the linear object F, and the winding device 4 on the full tube side is stopped.

At this time, it is preferable that the end of the kneaded material coming out of the winding device 4 and the linear objects entering the winding device #5 be gripped by an arbitrary gripping mechanism.

A bundle of linear objects of a certain length is taken out from the winding device #4 which has stopped until the empty winding device 5 is filled with the linear objects F, by the following operation.

As shown in FIG. 8, for example, after the winding device 4 with a full tube is moved onto the conveyor 21, the wire material is held down by the presser roll 2° to prevent the bundle F' of the wire material on the winding device from falling. holding a bundle of
A cutting blade is inserted into the transition point C (the position of the gate 14) from the non-defective track 9 to the defective track 1o of the linear material to cut it.

The tip of the cut bundle of linear objects F' is conveyed to the conveyor 21.
fall on top.

By cutting at the transition point, the leading end of the bundle F' of linear materials wound on the winding device 4 is separated into a bundle of good products and a bundle of defective products and falls.

Next, by continuously moving the conveyor 21 and the winding device 4 in the same direction and at the same speed, the bundle F' of linear materials of a certain length is separated into good products and defective products, and the wires are drawn without disturbing the bundle. It can be taken out in the longitudinal direction of the shaped object.

The empty winding device 4 is also moved to the winding position to prepare for the next switching.

As described above, by employing the operation of the present invention, it is possible to obtain a certain bundle of linear objects by distinguishing them into good products and defective products from continuous linear objects containing defects.

The present invention exhibits the following effects.

It is possible to process a continuous long linear object into a thicker bundle of linear objects without any disturbance.

When a continuous long linear object contains defects, it is possible to distinguish between good and defective products at the stage of constructing the linear object, which eliminates the involuntary work of removing defects after constructing the linear object. can.

Since the winding device is circular and has continuous rotational motion, it is possible to increase the speed. This method can be fully mechanized.

The method of the present invention can be widely used in the field of continuously manufacturing bundles of linear objects of a constant length.

Such fields include hollow fiber reverse osmosis membranes, hollow fiber ultrafiltration membranes, hollow fiber artificial kidneys, synthetic tatami mats, and brushes.
