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.
No. 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 this device, the linear body pulled out from the bobbin is guided between the first and second hollow shafts, and then pulled out through the linear body guide hole to one end of the central rotating shaft to perform twisting. Because of this, the drawing direction of the wire is opposite on the first hollow shaft side and the second hollow shaft side, and in the case of relatively hard wire materials such as hard copper wire, it is necessary to twist them on the first hollow shaft side. It has been found that the twisting habits differ between when twisting is performed and when twisting is performed on the second hollow shaft side, and it has been found that the quality may not be constant.

[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 has a structure in which one end half has a larger diameter than the other end half, and one end half has a larger diameter than the other end half. A large number of linear body guide holes are provided in the axial direction in a part of the large diameter part that is larger in diameter than the small diameter part on the other end, and a large diameter guide hole is provided in one end of the large diameter part in the axial direction. A central rotating shaft is formed with an enlarged diameter portion having a large number of wire through holes, and a large diameter portion on one end side of the central rotating shaft and a small diameter portion on the other end thereof are coaxial with each other and relative to the central rotating shaft. a first hollow shaft and a second hollow shaft rotatably mounted; a first bobbin group and a second bobbin group respectively mounted on the first hollow shaft and the second hollow shaft; A clutch mechanism is provided, which stops one of the first hollow shaft and the second hollow shaft when rotating the other, and stops one when rotating the other. The body passes through the wire through hole of the enlarged diameter section, and the wire body drawn from the second bobbin group passes through the wire guide hole of the large diameter section, and the wire body is drawn out to one end of the central rotating shaft. On the side where the hollow shaft is rotating, the linear bodies pulled out from the bobbin group are twisted or wound, and on the side where the central rotating shaft is stopped, the bobbin This is characterized in that the winding of the linear body into the group or the exchange of empty bobbins and fully wound bobbins is performed.

In this way, the drawing direction of the linear body becomes the same on the first hollow shaft side and the second hollow shaft side, and it becomes possible to make the twist tendency the same.

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, with a large diameter portion 11a on one end and a 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). Moreover, the central rotating shaft 11 has an enlarged diameter part 11c having a larger diameter at one end (outer end) of the large diameter part 11a, and a large number of wire through holes 14 are formed in the enlarged diameter part 11c in the axial direction. has been done.
This central rotating shaft 11 is hollow, and a core material 17 can be passed through the hollow portion 15 thereof. 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 at one end 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 enlarged diameter portion 11c and slidable in the axial direction;
and a flange 45 fixed to the enlarged diameter portion 11c.
It consists of letters such as a. The clutch plate 43a is always spline connected to the first hollow shaft 23a,
Regarding rotation and stopping, it is integrated with the first hollow shaft 23a. When the clutch plate 43a is moved to the left as shown in the figure, it is disengaged from the fixed frame 19 and engaged with the flange 45a, so that the rotation of the central rotating shaft 11 is caused by the rotation of the first hollow shaft 23a.
transmitted to. On the other hand, when the clutch plate 43a is moved to the right, the engagement with the flange 45a is broken and the clutch plate 43a is engaged with the fixed frame 19.
The first hollow shaft 23a is in a stationary state.

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.

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. It is guided to the outer end side of the core material 17 through the guide pulley 61, the wire through hole 14, and the guide pulley 63, and is pulled out to one end of the central rotating shaft 11, and after being spread at equal intervals by the guide roll 53, the wire is twisted onto the core material 17 by the twisting cap 55. are twisted together.

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 at one end becomes empty, the rotation of the first flyer 37a is stopped, and the guide roll 39b and guide Pulley 65, linear body guide hole 13, guide pulley 6
The wire body 38 pulled out through the twisting cap 5
5, and then connect it to the second flyer 37.
Rotate b and restart 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,
Small diameter part 11b, enlarged diameter part 11c, linear body guide hole 1
3, wire through hole 14, hollow part 15, bearing 18, fixed frame 19, wheel 21, first hollow shaft 23
a. The second hollow shaft 23b 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 71a is arranged coaxially,
It is rotatably supported via a bearing. Similarly, a second bobbin support 71b 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 71a with their axes perpendicular to the first bobbin support 71a. Similarly, the same number of bobbins 25b are attached to the second bobbin support 71b.

Further, both ends of a first rotating frame 73a are fixed to both ends of the first hollow shaft 23a, so that the first rotating frame 73a 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 73a has a flyer 7 that pulls out the linear body 38 from the bobbin 25a.
5a is attached to each bobbin. Although not shown, a similar flyer is also attached to the second rotating frame.

Further, the first hollow shaft 23a and the first bobbin support 71a can be locked against relative rotation by a first locking mechanism 77a. This lock mechanism 77a changes the relative position of the bobbin 25a and the first rotating frame 73a between a position where the first rotating frame 73a straddles the bobbin 25a (the position shown) and a position where the first rotating frame 73a 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 71b can be locked against relative rotation by a second locking mechanism 77b. This lock mechanism 77b 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.

Next, 79 is a linear body winding mechanism, and the motor 8
1 rotates the rotating arm 83, 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 71b is rotated to wind the wire into another empty bobbin. The linear object winding mechanism 79 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 79 is also movable toward the other bobbin 25a, and when the bobbin 25a is stationary, it moves thereto and winds 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 73a 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 75a are twisted together by the twisting nozzle 55 is the same as that in the embodiment shown in FIG.

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 twisting is being performed, the linear body 38 is wound onto the bobbin 25b by the linear body winding mechanism 79. 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.

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 this case, each bobbin may be made rotatable about its support shaft, and the linear body may be pulled out in the axial direction of the hollow shaft.

Although the embodiment shown in FIG. 4 shows a structure in which the bobbin is not attached or detached, the bobbin supports 71a and 71b are omitted and the bobbin is detachably attached to the first and second hollow shafts 23a and 23b. It is also possible to exchange empty bobbins and fully wound bobbins when the machine is stationary.

〔Effect of the invention〕

As explained above, according to the present invention, the first and second hollow shafts are provided on the central rotating shaft, the first bobbin group and the second bobbin group are attached to each, and twisting is performed on one side. In a wire twisting/winding device that allows winding of the wire onto an empty bobbin or exchanging an empty bobbin and a fully wound bobbin while Since the direction in which the linear bodies are drawn from the bobbin group is the same, the twisting habits of the linear bodies are the same no matter which way they are twisted together, which has the advantage that a product of consistent quality can be obtained.
