Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a device for twisting a large number of linear bodies together or winding them around a core material. The linear body mentioned here includes wire rods such as electric wires and metal wires, as well as strips (tape), strings, tubes, and the like.

In the following description, the twisting device will be mainly explained, but the same applies to the winding device.

[Prior art and its problems]

Conventionally, commonly used twisting devices attach a bobbin wrapped with wires and perform twisting, and when the bobbin becomes empty, the empty bobbin is replaced with a fully wound bobbin, and further twisting is performed. It's becoming like that. For this reason, it is necessary to stop the operation of the twisting device while replacing the bobbin, and there is a limit to improving the operating rate of the device.

As a twisting device that does not require bobbin replacement, a device called a SKET type is conventionally known. This is a hollow rotating shaft, and a large number of pairs of bobbins are provided in the longitudinal direction of the rotating shaft, coaxially and rotatably relative to the hollow rotating shaft, and between the two bobbins of each set, Each bobbin is equipped with a flyer that unwinds the wire from the bobbin.The flyer pulls out the wire from one of the bobbins in each set, and guides the drawn wire through the rotating shaft to one end where it is unwound. While twisting is performed, the other bobbin from which the linear body is not drawn out is rotated by an external drive to wind up the linear body.

In other words, this twisting device consists of two bobbins, and while the wire is pulled out from one bobbin and twisted, the wire is wound into the other bobbin, and one bobbin is twisted. When the bobbin is empty, the wire is pulled out from the other bobbin that has been wound and twisted, and this process is repeated to perform twisting almost continuously.

However, this twisting device has the following problems. That is, since a flyer is provided for each pair of bobbins, the structure becomes complicated and the price becomes high. Furthermore, since the length of the rotating shaft becomes long, the so-called wire threading operation, in which the linear body pulled out from the bobbin is pulled out to one end through the hollow part of the rotating shaft, is troublesome and the workability is poor.

Therefore, the inventor first provided first and second hollow shafts on the central rotating shaft, attached a plurality of bobbins to each of them, and while performing combustion matching on one shaft, the empty bobbins on the other hand were We proposed a device for twisting and winding wires that can wind wires or exchange empty and fully wound bobbins (patent application 1983).
−231311, Patent Application No. 1983-239089, Patent Application No. 1983-
No. 250697). This device can shorten the overall length of the device,
In addition to simplifying the structure, one half of the central rotating shaft is made into a large diameter part and the other half is made into a small diameter part, and a large number of linear body guide holes are formed in the large diameter part of the one end in the axial direction. It has the advantage that wire threading work can be easily performed.

However, in order to improve the strength of this device, it is necessary to increase the diameter of the central rotating shaft, and as a result, the diameters of the first and second hollow shafts and the bearings that support them also increase, resulting in an overall increase in size in the radial direction. It was found that there were some drawbacks, such as the number of rotations being limited.

[Means for solving problems and their effects]

The present invention provides a device for twisting and winding linear bodies that solves the above-mentioned problems, and is configured such that one half of the wire has a larger diameter than the other half. , a central rotating shaft in which a large diameter portion on one end side is larger in diameter than a small diameter portion on the other end side, and a large number of linear body guide holes are provided in the axial direction; A first hollow shaft and a second hollow shaft are respectively attached to the small diameter end portion coaxially and rotatably with respect to the central rotating shaft, and a first hollow shaft and a second hollow shaft are attached directly or indirectly to the first hollow shaft. a first bobbin group attached to the second hollow shaft, and a second bobbin group attached directly or indirectly to the second hollow shaft; and when one of the first hollow shaft and the second hollow shaft is rotated, the other is rotated. and a clutch mechanism that stops one when rotating the other, and on the side where the hollow shaft is rotating, the linear body pulled out from the bobbin group is inserted between the first and second hollow shafts. and further pulled out through the linear body guide hole of the central rotation shaft to one end of the central rotation shaft,

A device for twisting and winding linear bodies, characterized in that the central rotating shaft is supported by bearings at both ends as well as at an intermediate portion between the first and second hollow shafts. It is.

In this manner, the present invention aims at reducing the diameter of the central rotating shaft by providing a bearing also in the intermediate portion of the central rotating shaft, thereby reducing the overall size and increasing the speed.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 to 3 show one embodiment of the present invention. In the figure, reference numeral 11 denotes a central rotation shaft, and one half of the central rotation shaft 11 (on the right side of the drawing) has a larger diameter than the other half, and the large diameter portion 11a on one end is larger than the small diameter portion 11b on the other end. A large number of linear body guide holes 13 are formed in the axial direction in the large diameter portion (see FIG. 2). This central rotating shaft 11 is hollow,
A core material 17 can be passed through the hollow portion 15. Further, the central rotating shaft 11 is rotatably supported by a fixed frame 19 via bearings 18 at both ends thereof, and is rotatably driven from the outside via a wheel 21 attached to the other end. .

A first hollow shaft 23a is coaxially disposed on the outer periphery of the large diameter portion 11a on one end side of the central rotating shaft 11, and is rotatably supported via a bearing. Similarly, a second hollow shaft 23b is coaxially arranged on the outer periphery of the small diameter portion 11b on the other end side of the central rotating shaft 11, and is rotatably supported via a bearing.

Further, a large number of bobbins 25a are arranged coaxially around the outer periphery of the first hollow shaft 23a, and each bobbin 25a is rotatably supported with respect to the first hollow shaft 23a via a bearing. These bobbins 25a constitute a first bobbin group 27a. Similarly, a large number of bobbins 25b are arranged coaxially around the outer periphery of the second hollow shaft 23b, and each bobbin 25b is rotatably supported with respect to the second hollow shaft 23b via a bearing. These bobbins 25b are the second bobbin group 2.
7b.

A gear 29 is integrally provided on one side of each bobbin 25a, 25b, and an electromagnetic clutch 31 for braking is provided on the opposite side. The electromagnetic clutch 31 of the first bobbin group 27a is supplied with power from one end of the fixed frame 19 via a brush 33a and a slip ring 35a, and the electromagnetic clutch 31 of the second bobbin group 27b is supplied with electricity from the other end of the fixed frame 19. Power is supplied from the end side via the brush 33b and slip ring 35b.

Further, a first flyer 37a that straddles the first bobbin group 27a is fixed to both ends of the first hollow shaft 23a, and rotates together with the first hollow shaft 23a. Similarly, the second hollow shaft 23b
A second flyer 37b that straddles the second bobbin group 27b is fixed to both ends of the second hollow shaft 23b.
It is designed to rotate as one. A guide roll 39a is attached to the first flyer 37a for guiding the linear body 38 drawn out from the bobbin 25a. A similar guide roll 39b is also attached to the second flyer 37b.

Further, a clutch mechanism 41a is provided between one end of the first hollow shaft 23a and the fixed frame 19. This clutch mechanism 41a has a central rotating shaft 11.
a clutch plate 43a that is rotatable relative to the clutch plate 43a and slidable in the axial direction;
It consists of a flange 45a fixed to 1, etc. The clutch plate 43a is always spline connected to the first hollow shaft 23a, and is integral with the first hollow shaft 23a regarding rotation and stopping. When the clutch plate 43a is moved to the left as shown in the figure, it disengages from the fixed frame 19 and engages with the flange 45a, so that the central rotation shaft 11
rotation is transmitted to the first hollow shaft 23a. Conversely, when the clutch plate 43a is moved to the right, the engagement with the flange 45a is broken and the fixed frame 1
9, the first hollow shaft 23a
becomes stationary.

A similar clutch mechanism 41b is also provided between the other end of the second hollow shaft 23b and the fixed frame 19. In the illustrated state, the clutch plate 43b is moved to the left, disengaged from the flange 45b, and engaged with the fixed frame 19. In other words, the second hollow shaft 23b is in a stationary state.

Next, 47 is a bobbin drive mechanism, which drives the rotation of the drive shaft 49 arranged parallel to the central rotating shaft 11 from the outside to the bobbin 25b by meshing with a gear train 51 and a gear 29 attached to the bobbin 25b. It rotates and drives. As shown in FIG. 3, this bobbin drive mechanism 47 includes a bobbin 25b
It can be set to a drive position (solid line) where it meshes with the gear 29, and a retracted position (dotted line) where it does not mesh with the gear 29 and does not interfere with the rotation of the flyer 37b. As shown in the figure, the bobbin drive mechanism 47 is set to the drive position when the rotation of the flyer 37b is stopped, and meshes with the gear 29 to rotationally drive the bobbin 25b. It involves 38 people. Of course, when rotating the bobbin 25b,
The flyer 37b is kept stationary at a position where movement of the bobbin drive mechanism 47 is not hindered.

In the illustrated example, since there is one set of bobbin drive mechanisms 47, the bobbin drive mechanisms 47 are moved in the axial direction to wind up the linear body for each bobbin. Bobbin drive mechanism 47
is also movable toward the first bobbin group 27a, and when the first flyer 37a is stationary, it rotates that bobbin 25a to feed the linear body supplied thereto from the outside. Get involved. Note that if the bobbin drive mechanism 47 is provided for each bobbin, it is possible to simultaneously wind the linear bodies onto a large number of bobbins at once.

Now, in order to reduce the diameter of the central rotating shaft 11, this device has a structure in which the intermediate portion of the central rotating shaft 11 is supported by a bearing. That is, the central rotation axis 1
A hub 61 is fixed to the outer periphery of the inner end of the large diameter portion 11a, which is the middle portion of the frame 1, and this hub 61 is supported by the fixed frame 19 via a bearing 63. A required number of wire through holes 65 are formed in the hub 61, and these wire through holes 65 are connected to the wire body 38.
The hub 61
There are the same number of guide pulleys 6 as wire through holes 65 on both sides of the
7,69 are installed.

Next, the operation of this device will be explained. In the illustrated state, the center rotation shaft 11 is
and the first hollow shaft 23a are directly connected, and the first flyer 37a is rotating around the first bobbin group 27a. Therefore, the linear bodies 38 are pulled out from each bobbin 25a by the rotation of the flyer 37a (the pulling tension is adjusted by the electromagnetic clutch 31), and the drawn out linear bodies 38 are moved by the guide rolls 39a to the first hollow shaft 23a. The central rotating shaft 11 The fibers are pulled out at one end, separated at equal intervals by a guide roll 53, and then twisted onto the core material 17 by a twisting nozzle 55.

On the other hand, on the other end side, the fixed frame 19 and the second hollow shaft 23b are directly connected by the clutch mechanism 41b, and the second flyer 37b is in a stationary state.
The linear body 38 is wound around b. When each bobbin 25b is fully wound, the bobbin drive mechanism 47
Set it in the retracted position and prepare for the next twisting.
Immediately before the bobbin 25a on one end side becomes empty, the rotation of the first flyer 37a is stopped, and the linear bodies 38 pulled out from the bobbin 25b on the other end side are attached to the rear end of each linear body 38 on the guide pulley 69. After that, the second flyer 37b is rotated to resume twisting. Twisting is performed continuously by repeating the above operations.

In the above embodiment, a case has been described in which one linear body is wound on each bobbin, but two or more linear bodies may be wound on each bobbin in parallel.

Next, FIG. 4 shows another embodiment of the present invention. In this device, a central rotating shaft 11, a large diameter portion 11a,

In this device, on the outer periphery of the first hollow shaft 23a,
A large number of them are perpendicular to each other (e.g. in the circumferential direction).
Four bobbins 25a are supported at 90° intervals. Each bobbin 25a can be attached to and detached from the hollow shaft 23a. Similarly, on the outer periphery of the second hollow shaft 23,
A large number of bobbins 25b are removably supported.

Further, bobbins 2 are provided at both ends of the first hollow shaft 23a.
Both ends of the first rotating frame 71a that straddles the first rotating frame 71a are fixed so that it rotates together with the first hollow shaft 23a. Similarly, the second hollow shaft 23

It is designed to rotate together with 3b.
A flyer 73a for drawing out the linear body 27 from the bobbin 25a is attached to the first rotating frame 71a for each bobbin 25a. A similar flyer 73b is also attached to the second rotating frame 71b.

The operation of this device is as follows. In the illustrated state, the central rotating shaft 11 and the first hollow shaft 23a are directly connected by the first clutch mechanism 41a, and the first rotating frame 71a and the bobbin 25a are rotating together with the first hollow shaft 23a. . The linear body 27 pulled out from each bobbin 25a by the rotation of the flyer 33a is guided to the inner end side of the first hollow shaft 23a by the guide roll 39a on the rotating frame 71a, and is guided by the guide pulley 67, the wire through hole 65, After passing through the guide pulley 69 and further passing through the linear body guide hole 13 formed in the large diameter portion 11a of the central rotating shaft 11 to one end of the central rotating shaft 11, and being separated at equal intervals by the guide roll 53. , are twisted together on the core material 17 using the twisting cap 55. On the other hand, on the other end side, the fixed frame 19 and the second hollow shaft 23b are directly connected by the clutch mechanism 41b, and the second rotating frame 71b is in a stationary state, so that it becomes empty while the above twisting is performed. The finished bobbin 25b and the fully wound bobbin (not shown) are replaced in preparation for the next twisting. Then, just before the bobbin 25a at one end becomes empty, the rotation of the first rotating frame 71a is stopped, and the linear bodies 38 pulled out from the bobbin 25b at the other end are attached to the rear end of each linear body 38 by the guide pulley 69. After that, the second rotating frame 71b is rotated to retwist. Combustion is performed continuously by repeating the above operations.

In the embodiment shown in FIG. 4, the case where one wire body is wound around each bobbin has been explained, but two wire bodies are wound around each bobbin.
It is also possible to wind the bobbin with one twist per turn of the filament.

In addition, in the embodiment shown in Fig. 4, the filament wound around the bobbin is pulled out in the axial direction of the bobbin by a flyer, but if the filament is a tape or two or more filaments are wound in parallel. In such a case, each bobbin may be made rotatable about its respective support shaft, and the linear body may be drawn out in the axial direction of the hollow shaft.

Next, FIG. 5 shows still another embodiment of the present invention. In this device, a central rotating shaft 11, a large diameter portion 11a, a small diameter portion 11b, a linear body guide hole 13, a hollow portion 15, a bearing 18, a fixed frame 19, a wheel 21, a first hollow shaft 23a, a second hollow Axis 23
b is the same as in the previous embodiment.

In this device, on the outer periphery of the first hollow shaft 23a,
A first bobbin support 81a is arranged coaxially,
It is rotatably supported via a bearing. Similarly, a second bobbin support 81b is coaxially arranged on the outer periphery of the second hollow shaft 23b and rotatably supported via a bearing.

Further, a plurality of (two in the illustrated example) bobbins 25a are attached to the first bobbin support 81a with their axes perpendicular to the first bobbin support 81a. Similarly, the same number of bobbins 25b are attached to the second bobbin support 81b.

Further, both ends of a first rotating frame 71a are fixed to both ends of the first hollow shaft 23a, so that the first rotating frame 71a rotates together with the first hollow shaft 23a. Similarly, both ends of a second rotating frame (not shown) are fixed to both ends of the second hollow shaft 23b,
It rotates together with the second hollow shaft 23b. The first rotating frame 71a has a flyer 7 that pulls out the linear body 38 from the bobbin 25a.
3a is attached to each bobbin. A similar fryer is also attached to a second rotating frame (not shown).

Further, the first hollow shaft 23a and the first bobbin support 81a can be locked against relative rotation by a first locking mechanism 83a. This locking mechanism 83a changes the relative position of the bobbin 25a and the first rotating frame 71a between a position where the first rotating frame 71a straddles the bobbin 25a (the position shown in the figure) and a position where the first rotating frame 71a does not straddle the bobbin 25a (a position perpendicular to the plane of the paper). ). Similarly, the second hollow shaft 23b and the second bobbin support 81b can be locked against relative rotation by a second locking mechanism 83b. This lock mechanism 83b is
The relative position between the bobbin 25b and the second rotating frame (not shown, but located perpendicular to the plane of the paper) is
This is for locking the second rotating frame in a position where it straddles the bobbin 25b (the same position as in the paper) and a position where it does not straddle the bobbin 25b (a position perpendicular to the paper).

Also, the clutch mechanism 41 on the first hollow shaft 23a side
The structures of the clutch plate 43a, flange 45a, clutch mechanism 41b on the second hollow shaft 23b side, clutch plate 43b, and flange 45b are the same as in the previous embodiment.

Further, a hub 61,
Bearing 63, wire through hole 65, guide pulleys 67, 6
9 is also the same as in the previous embodiment.

Next, 85 is a linear body winding mechanism, and a motor 8
7 rotates the rotary arm 89, and the linear body 38 is supplied from the outside to the stationary bobbin 25b.
It is something that involves. After winding the wire into one bobbin, the bobbin support 81b is rotated to wind the wire into another empty bobbin. The linear object winding mechanism 85 is retracted to a position where it does not come into contact with the rotating frame when the linear object is not being wound. The linear body winding mechanism 85 is also movable toward the other bobbin 25a, and when the bobbin 25a is stationary, it moves thereto to wind the linear body. If a linear body winding mechanism is provided for each bobbin, it is possible to simultaneously wind the linear body onto a large number of bobbins.

The operation of this device is as follows. In the illustrated state, the center rotating shaft 11 and the first hollow shaft 23a are directly connected by the first clutch mechanism 41a, and the first rotating frame 71a is locked in a position where it straddles the bobbin 25a. And the bobbin 25a is rotating together with the central rotating shaft 11. The path through which the linear bodies 38 drawn out from each bobbin 25a by the rotation of the flyer 73a are twisted together by the twisting nozzle 55 is the same as that in the embodiment shown in FIG. 4.

On the other hand, on the other end side, the fixed frame 19 and the second hollow shaft 23b are directly connected by the clutch mechanism 41b, and the bobbin 25b is in a stationary state. Further, the second rotating frame is locked in a position where it does not straddle the bobbin 25b (a position perpendicular to the plane of the paper). In this state, while the above-mentioned twisting is being performed, the linear body 38 is wound onto the bobbin 25b by the linear body winding mechanism 85. When each bobbin 25b is fully wound, the second rotating frame is returned to the position where it straddles the bobbin 25b and locked, in preparation for the next twisting. The subsequent operations are the same as in the embodiment shown in FIG.

〔Effect of the invention〕

As explained above, according to the present invention, first and second hollow shafts are provided on the central rotating shaft, and a plurality of bobbins are attached to each of the hollow shafts, so that while one is being twisted, the other is empty. In a wire twisting/winding device that is capable of winding a wire onto a bobbin or exchanging an empty bobbin with a fully wound bobbin,
Since the central rotating shaft is supported by bearings not only at both ends but also in the middle, the strength of the central rotating shaft can be reduced, and the diameter of the central rotating shaft can be reduced, which has the advantage of making the whole machine smaller and faster.
