DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire winding device for measuring a length of a low-strength wire such as an optical fiber or a thin metal wire while winding the wire on a winding drum.

[0002]

2. Description of the Related Art Conventionally, a measuring instrument for measuring a length while winding a wire rod used in an electric wire store is shown in FIG.
The structure shown in FIG. That is, the stripped wires and wires 10 are placed on a turntable 102 on a gantry 101, and the wires 10 are manually pulled out, passed through a measuring roller 103, and taken up by a winding drum 104.
(It may be a parasol). The manual handle 105 is rotated in the direction a in FIG. The display of the length by the measuring rule is mainly performed by reading the cumulative rotation angle (number of rotations × angle) of the measuring roller 103 using a measuring instrument 106 which is a mechanical counter.

[0003] Here, the cumulative rotation angle means a rotation speed n,
Assuming that the rotation angle from the reference point is θ, it refers to a numerical value represented by the product of nθ. This numerical value can be expressed by a relatively simple mechanical device. That is, if a scale plate corresponding to θ is provided on the gear, and a mechanical counter for accumulatively adding the gear every time the gear rotates once and the gear with the scale plate are interlocked, this can be easily obtained. . Therefore, measuring instrument 1
In order that the length of the electric wire can be represented by the cumulative rotation angle of 06, the size of the measuring roller 103, the gear ratio of the measuring instrument 106, and θ
Is prepared in advance so that the line length can be displayed, the cumulative rotation angle displayed by the measuring instrument 106 indicates the line length of the electric wire.

[0004] As described above, in the conventional length measuring device of the wire winding machine, the measuring roller 103 is connected to the wire rod 1.
It is performed by rotating by touching 0, and the length display can be easily displayed by the above-described method.
It is widely used without fundamental improvements.
Although an improved wire winding machine can be seen, the measuring instrument 106, which is a mechanical counter, has been replaced by an electric counter or a computer, and the entire apparatus has a structure similar to that of FIG. And electric wires and wires 10
The measuring roller 103 is still used for measuring the length of the wire.

[0005]

In recent years, the change in the industrial structure that is rushing into the industrial world has prompted the transition from the age of mass consumption and mass production to the age of information technology.
It is not immune to this change in industrial structure. This can be inferred from the fact that the main products of electric wires are changing from thick transmission lines and distribution lines to thin communication lines. On the other hand, the wire winding machine uses a machine having the same structure as that of the conventional one, so that a product defect often occurs in the wire. The main cause of product failure is measuring roller 1
03 damages the insulating coating of the wire 10 or the wire 1
0 itself was broken. As a result of the investigation, it was found that most of the product defects occurred when winding up the communication line. That is, the communication line in which the failure occurred is an optical fiber (outer diameter 125 μm = 0.125 mm)
And copper wire (outer diameter 0.13 mm), which is a core material of the wire, and gold wire for circuit wiring, etc., and the main electric wire in the modern age in the information age is a communication wire. Therefore, with the increase in the handling amount, the number of defective products has increased.

Generally, a thin wire such as an optical fiber, a gold wire, and a communication wire has low strength and is weak to an impact load in a tensile direction. In particular, when a lateral pressure is applied to the wire when a tensile load is applied. It has the property of easily breaking. As a result of investigating the cause of the disconnection, when a low-strength line such as an optical fiber or a communication line is measured by the conventional measuring device of FIG. 9, the measuring roller 103 applies lateral pressure to the wire 10,
Furthermore, since the winding drum 104 interlocked with the manual handle 105 applies a load to the wire 10 in the tensile direction,
At the portion where the measuring roller 103 and the wire 10 are in contact, the wire 1
0 was found to break.

[0007] Therefore, it is considered that such a problem will not occur if the measurement of the wire is performed by a non-contact method. As a result of studying the introduction of several technologies, a thin wire such as an optical fiber is measured by a non-contact method. It has been found that the optical Doppler method using a laser is a good method for performing the measurement by using.
However, it has been found that this measurement method is not suitable for measuring the length of a short wire rod that needs to be frequently changed in speed, since a constant linear speed is a prerequisite for measuring the length. . The present invention has been obtained as a result of conducting various studies as described above, and accurately measures the outer diameter information of a winding drum for winding a wire using a non-contact method (measuring means). It is an object of the present invention to provide a wire winding device capable of measuring the length of a thin wire without damaging or breaking the wire.

[0008]

In order to achieve the above object, the present invention provides a wire winding device for measuring the length of a wire while winding a low-strength wire such as an optical fiber or a thin metal wire on a winding drum. In the above, the wire wound on the winding drum is to be removed from the apparatus as a product integrally with or separately from the winding drum, and the outer diameter information of the winding drum is stored in a portion different from the winding drum. It comprises a replaceable outer diameter information transmitting means for transmitting in a non-contact manner, and a measuring means for measuring a winding length of a wire rod by measuring a cumulative rotation angle based on the outer diameter information transmitting means. is there. As the outer diameter information transmitting means, a proportional equivalent disk having the same diameter as the winding drum and connected via a power transmission element can be used. This proportional equivalent disk (outer diameter plate in the embodiment) can be used. By measuring the cumulative rotation angle of the proportional equivalent disk by applying measuring means (measuring roller in the embodiment) to the measuring means, the measuring means measures the strip length of the wire by equivalent conversion without contacting the wire. You can do it.

Further, the present invention relates to a wire winding device for measuring the length of a wire while winding a low-strength wire such as an optical fiber or a thin metal wire around the winding drum. An exchangeable outer diameter information transmitting means for transmitting the outer diameter information of the winding drum in a non-contact manner with the wire material, the outer diameter information being provided integrally with or separately from the winding drum as a product; Measurement means for calculating the winding length of the wire rod based on the outer diameter information of the winding drum transmitted by the transmitting means and the number of rotations of the winding drum is provided. And
As the outer diameter information transmitting means, an optical laser measuring device or a mechanical encoder device can be used. Can be measured.

[0010] In the wire winding device of the present invention, while the wire is wound, the measuring means (a measuring roller or the like) can measure the wire length in a non-contact manner with the wire, so that the breakage of the wire is eliminated. Is done. In addition, the apparatus of the present invention is not always suitable for measuring the length of a long wire or a thick wire, and is not always suitable, but measures a wire having a diameter of 10 μm to 1 mm with a length of about 10 m to 300 m. Has a sufficiently small error and is within the range of the test error, does not cause any problem, and is suitable for practical use. In other words, usually, the length of the wire sold at the store is in a unit of 10 m to 50 m,
If the diameter of the wire is about 0.125 mm to 1 mm, the error in the measurement strip length is sufficiently negligible.

FIG. 1 is an external view of a wire winding device according to a first embodiment of the present invention. The wire take-up device is provided on the gantry 1 and is provided with a wire 1 as a wire supply means.
0, a take-up (also called take-up) drum 3 as a wire take-up means for taking up the wire 10 from the feed drum 2, and a manual handle for manually driving the take-up drum 3 4, a winding shaft 5 of the winding drum 3 and a transmission mechanism 6 (see FIG.
(A power transmission element shown in FIG. 2), and an outer diameter plate (proportional equivalent disk) 7 as an outer diameter information transmitting means of the winding drum 3 and a measuring rule as a measuring means brought into contact with the outer diameter plate 7. A roller 8 and a measuring instrument 9 for measuring the cumulative rotation angle of the measuring roller 8 are provided. The outer diameter plate 7 is the winding drum 3
A member having the same diameter as that of the wire rod 10 attached to the measuring shaft 11 and measuring the rotation of the outer diameter plate 7 to be wound up.
Can be obtained by equivalently converting the length.

Further, this apparatus is provided with a traverser 12 for aligning and winding, for the purpose of adjusting the appearance of the product wound on the winding drum 3 and stabilizing the measuring accuracy. Is not always required.
The feed drum 2 is provided with an auxiliary power mechanism 14 on the supply shaft 13 of the feed drum 2 for the purpose of smoothing the rotation of the feed drum 2 and lowering its rotational resistance. It is not always necessary if the weight of the is light. The alignment winding traverser 12 and the auxiliary power mechanism 14 may be appropriately selected and mounted according to the user's request. The delivery drum 2 and the take-up drum 3 are supported on the gantry 1 by a tiltable stand 15. I have. The drums 2 and 3 have respective shafts 13 and
In the state attached to the shaft 5, all are fixed to the shaft.

FIG. 2 shows a power transmission element constituting the transmission mechanism 6 described above. The transmission pulley 1 corresponds to each of the winding shaft 5, the supply shaft 13, and the traverser drive shaft 16.
7, a belt 18 is wound between the winding shaft 5 and the transmission pulley 17, between the winding shaft 5 and the measuring shaft 11, and between the transmission pulleys 17, and between the supply shaft 13 and the transmission pulley 17, A removable belt 19 is hung between the traverser drive shaft 16 and the transmission pulley 17. In FIG. 1, components and mechanisms such as a hinge for folding the display lamp and the stand 15 and a lock mechanism are not shown. Similarly, FIG. 2 omits illustration of sensors, a disconnection alarm, a manual force synchronizer, a buffer mechanism, and a braking device.

Next, the winding operation of the wire rod 10 by the above-configured apparatus will be described. As the wire 10, a product drum on which a thin wire such as an optical fiber or an enamel wire is wound is set on the supply shaft 13 as the delivery drum 2. Then, the bobbin for sale is set on the winding shaft 5 as the winding drum 3. Next, the outer diameter plate 7 having the same outer diameter as the body diameter of the winding drum 3 is attached to the measuring shaft 1.
1, the measuring roller 8 is pressed against the outer diameter plate 7 to transmit the rotation of the measuring roller 8 to the measuring instrument 9. In this state, the wire 10 is pulled out from the delivery drum 2 so as not to sag, and wound around the winding drum 3 so as not to be cut. When it is confirmed that the wire rod 10 is wound around the winding drum 3, when the manual handle 4 is rotated in the direction a in FIG. 1, each shaft is driven via the power transmission element of the transmission mechanism 6. The wire 10 can be wound around the winding drum 3.

At this time, the power transmission element operates as shown in FIG. 2, and the force of rotating the manual handle 4 in the a direction acts on the winding shaft 5 to rotate it in the a direction. A belt 18 is hung on the winding shaft 5, and this also starts to move in the direction a in FIG. The force transmitted by the belt 18 rotates the measuring shaft 11, and the outer diameter plate 7 starts rotating in synchronization with the manual handle 4. Since the outer diameter plate 7 is interlocked with the measuring instrument 9 via the measuring roller 8, the accumulated rotation angle indicates the length of the wire 10. As described above, the outer diameter plate 7 is interlocked with the winding shaft 5 and
When the outer diameter of the outer diameter plate 7 is adjusted to the body diameter of the winding drum 3, the strip length can be equivalently measured based on the cumulative rotation angle of the outer diameter plate 7. As a result, the measurement of the length of the wire 10 can be performed without the measuring roller 8 being in contact with the wire 10. Therefore, the wire 1
0 does not break. When the diameter of the winding drum 3 is changed, the outer diameter plate 7 may be replaced with another one.

Further, by appropriately adding a conductive pulley 17 to the winding shaft 5 linked to the manual handle 4, a rotating force synchronized with the manual handle 4 can be given to an external device. FIG. 2 shows this state, and the transmission pulley 17 is shown.
By attaching a removable belt 19 to the traverser drive shaft 16 and the supply shaft 13, the rotational force from the manual handle 4 is transmitted. Therefore, the manual handle 4 is attached to the aligning winding traverser 12 and the auxiliary power mechanism 14.
Power from the vehicle. By appropriately selecting the attachment of the detachable belt 19, it is possible to add these devices and other devices that wish to synchronize with the manual handle 4.

Further, in the present apparatus shown in FIG. 1 as the outer diameter information transmitting means, the outer diameter plate 7 is used, and thereby, the procurement price of the entire apparatus is reduced to the present state (the price as of 1995).
Can be set to several hundred thousand yen or less and 30,000 yen or more.
Cost reduction can be achieved. This eliminates the need to introduce a computer by using the outer diameter plate 7, and can save labor costs for software production and hardware development, and as a result, such a low price can be realized. At present, in order to obtain the same effect as the device of the present invention with an optical fiber winding machine, a capital investment of 6 million yen to tens of millions of yen is required. Cost performance of several hundred times can be obtained. Note that the present invention is not limited to the use of the outer diameter plate 7 as the outer diameter information transmitting means, but may have a configuration in which a laser and a computer are combined as described later.

Next, a description will be given of a modification of the first embodiment. The delivery drum 2 serving as the wire supply means may be a turntable 102 as shown in FIG. What is necessary is just a form which has a structure which can be supplied stably. In the winding of a thin wire such as an optical fiber, in the case of a length of 10 m or less, once the wire is naturally dropped on the floor, and then slowly wound around the winding drum 3. Even such a primitive wire supply means can be employed for winding a short wire. Similarly, in the winding drum 3 as the wire winding means, a machine called a parasol generally used in an electric wire winding machine may be used, and the wire can be wound stably and reliably. As long as the means can be used, various configurations can be adopted according to the shape and use form of the device.

The auxiliary power mechanism 14 in the present apparatus
When the auxiliary power mechanism 14 is not used, a stand 15 may be provided at a place where the auxiliary traverser 12 is mounted. In addition, it is possible to wind up the wire rod 10 that has been stripped using the present apparatus. In this case, the turntable 102 shown in FIG. 9 is provided in a place where the stand 15, the delivery drum 2, and the auxiliary power mechanism 14 have been removed, or in an appropriate space of the gantry 1, and a tapping product is placed on the turntable 102. Can be done with Further, in the device of this embodiment, it is possible to wind the wire rod 10 hanging on the floor.

FIG. 3 is an external view of a wire winding device according to a second embodiment. In the second embodiment, the manual handle 4 is attached separately from the winding drum 3 so that manual vibration and impact are not transmitted directly to the winding drum 3. Winding with even higher precision than the apparatus of the embodiment can be performed. In addition,
The power transmission element of the transmission mechanism 6 is not shown, but the manual handle 4 and the winding drum 3 are connected via a power transmission mechanism. Also, although the alignment winding traverser 12 is omitted, it can be attached later.

FIG. 4 is an external view of a main part of a wire winding device according to a third embodiment. The third embodiment is an improvement of the device of the second embodiment, in which an outer diameter plate 7 used as outer diameter information transmission means is arranged coaxially with the winding drum 3, and the size of the winding drum 3 is reduced. This has the effect of preventing the user from forgetting to replace the outer diameter plate 7 when it is changed. Also,
There is also an effect that the structure is simplified and handling becomes easy. The manual handle 4 may be coaxial with the winding drum 3 as in the first embodiment, or may have the same configuration as in the second embodiment.

FIG. 5 is a conceptual diagram of a wire winding device according to a fourth embodiment. The apparatus of this embodiment utilizes belt conduction as an outer diameter information transmitting means, and the winding drum 3, the outer diameter plate 7 and the manual handle 4 are connected by a connecting shaft 20, and the outer diameter plate 7 and the transmission pulley 17 are connected. Means that the length of the belt 18 is measured by measuring the amount of movement of the belt 18 with the measuring roller 8 and the measuring instrument 9. The apparatus of this embodiment differs from the first and second embodiments in that a belt 18 for driving a measuring roller 8 is directly applied to the outer diameter plate 7. The operation is the same. According to this configuration, the measuring roller 8 and the measuring instrument 9 basically have the same structure as that of FIG.
Can be used and the cost performance is relatively good.

FIG. 6 is a block diagram of the measuring instrument 9 in the case where the electric outer diameter information transmitting means according to the fifth embodiment is used.
In this embodiment, the measuring instrument 9 is not constituted by a mechanical counter, but is constituted by an electric counter. The rotation of the winding shaft 5 is detected by a sensor 31 (or an encoder) and a counter 32. It is like that. The arithmetic unit 33 calculates the length of the wire based on the cumulative rotation angle based on the output of the counter 32 and the input of the outer diameter information (numerical value) of the winding drum 3 based on the electric signal from the outer diameter information transmitting means. Is displayed on the display 34. The input to the arithmetic unit 33 may be an input of a selection switch selected according to a predetermined type of the winding drum 3 instead of the outer diameter information.

FIGS. 7 and 8 are diagrams showing specific examples of the electric outer diameter information transmitting means. FIG. 7 shows a case where a laser is used.
FIG. 8 shows a case where an encoder is used. In FIG.
The point-like laser light from the laser device 41 is converted into a linear beam light by the scanner optical system 42, that is, a beam line 43.
Is converted to The beam line 43 is irradiated onto the winding drum 3 as shown in the figure, and transmits the size of the winding drum 3 to a line sensor 44. That is, if the beam line 43 is set so as to cover the body diameter portion of the winding drum 3, the shadow of the drum is projected on the line sensor 44, and the outer diameter information of the winding drum 3 is converted into an electric signal. This electric signal is input to an electric measuring instrument 9 shown in FIG. 6, and is used for measuring the length.

In the example shown in FIG. 8, a rotatable measuring arm 45 is brought into contact with the diameter portion of the winding drum 3 and the encoder 4 is rotated.
The body diameter of the winding drum 3 is obtained from the movement amount of the measurement arm 45 from the reference point No. 6, and the movement amount is represented as θ in the figure. The movement amount thus obtained is transmitted to the arithmetic unit 33 shown in FIG. 6 by the counter 32 as an electric signal of the outer diameter information, and the length measurement is performed.
There are two ways to use this method. One is to apply the measuring arm 45 to the winding drum 3 before winding and confirm that the outer diameter information has been transmitted to the arithmetic unit 33. And the other is to store the measurement arm 4
In this method, a frame having a small rotational resistance is attached to the reference numeral 5, and the outer diameter is continuously monitored even during winding. Further, the outer diameter plate 7 may be used instead of the winding drum 3, and the measurement arm 45 may be applied to the outer diameter plate 7.

The present invention is not limited to the configuration of the above embodiment, and various modifications are possible. For example, by changing the gear ratio of the measuring instrument to make the size of the outer diameter plate different from that of the winding drum, using a fishing reel for wire winding means or wire feeding means, or using a transformer, It is also possible to apply a device for winding such an electric coil, and furthermore, as exemplified by incorporating a power or shock absorber capable of cooperative operation (synchronous operation) with manual force, the present invention Without departing from the gist, it is also possible to use or replace devices, circuits and means having predetermined technical functions and their configurations.

[0027]

As described above, in the wire winding apparatus of the present invention, the outer diameter information of the winding drum can be accurately transmitted to the measuring means by using the outer diameter information transmitting means in a non-contact manner. In addition, it is possible to perform a highly reliable measurement of the length while winding the wire without damaging or breaking the wire. In particular, there is an advantage that the strip length can be measured without breaking a low-strength thin wire such as an optical fiber, a gold wire, and an enamel wire having an outer diameter of 1 mm or less. Further, by using an outer diameter plate having the same diameter as the winding drum as the outer diameter information transmitting means, the configuration can be greatly simplified and an inexpensive device can be realized. Further, by calculating the winding length of the wire based on the outer diameter information of the winding drum transmitted by the outer diameter information transmitting means and the number of rotations of the winding drum, a method of non-contact with the wire can be obtained. In addition, the winding length of the wire can be measured. As the outer diameter information transmitting means, an optical or mechanical measuring device can be used,
The outer diameter information is used as an electric signal, and by using this electric signal, a highly reliable strip length measurement can be performed without damaging or breaking the low-strength thin wire.
