Description

Winding device, manufacturing equipment using the same, winding method and finished product manufacturing method

The present invention relates to a wire winding device for winding a wire around an outer periphery parallel to a rotation axis of a rotating winder, a manufacturing facility using the same, a winding method, and a finished product manufacturing method.

Conventionally, a wire winding method is known in which a coil bobbin, which is a winder, is attached to a winder holder and rotated, and a wire rod fed from a nozzle is wound around the coil bobbin and wound. Further, as a method of rotating the winder holder, a plurality of winder holders are connected to a rotating shaft of a single motor via a belt, and the plurality of winder holders are simultaneously connected by a single motor. It is known to rotate in the same direction.

However, if the motor is connected to the winder holder via a belt, the belt may be worn or stretched due to use and loosening may occur. As a result, the belt crest may jump over the crest of the pulley provided on the rotating shaft of the motor or the winder holder to cause a shift in the rotational position. Further, since there are many mechanical contact portions, energy loss at the contact portions is large, and there is a problem of heat generation due to wear.

In order to solve this problem, JP2002-43157A has a plurality of winding tool holders that can be rotated by attaching a winding tool, pivoted on a single base so as to be parallel to each other, and a plurality of winding tools can be mounted. A winding device is disclosed in which a rotary drive source is individually connected to a grip holder. In this winding measure, the controller rotates a plurality of rotational drive sources separately provided on the winder holder in synchronization with each other.

According to this winding device, a plurality of the same type of winding products can be obtained at a time by rotating a plurality of rotational drive sources in synchronization with each other. Since this winding apparatus does not use a belt coupling mechanism, there is no shift in rotational position due to belt wear, there is little energy loss, and there is no fear of heat generation due to wear.

Here, in recent years, it is also required to manufacture a small number of various types of winding products. Even when the same winding tool and wire are used, assembling and completing multiple types of winding products with different numbers of windings, winding directions, and pull-out positions of the wire It may be a product.

For example, when two types of winding products are assembled to obtain a finished product, two

winding devices

1 and 2 are prepared as shown in FIG. It is conceivable that the winding products 3a and 3b are separately obtained in step 2. After obtaining two different types of winding products 3a and 3b, the conveyor 4 transports the two types of winding products 3a and 3b to the assembling machine 6 via the inspection machine 5, and in the assembling machine 6 A finished product is obtained by assembling the two types of winding products 3a and 3b.

In this way, when a plurality of types of winding products 3a and 3b are assembled to obtain a finished product, winding products 3a and 3b having different specifications are required. 2 must be placed along the conveyor 4. Moreover, when the

winding devices

1 and 2 for the number of specifications are arranged along the conveyor 4, the cost increases because it is necessary to prepare a plurality of winding

devices

1 and 2, and the plurality of winding devices 1 and 2 A relatively large installation space is required in order to install with a gap necessary for work.

In addition, when a defect occurs due to the inspection performed by the inspection machine 5, the number of good winding products 3a and 3b supplied to the assembly machine 6 will not match. In this case, it becomes necessary to discard one lot or to supply spare winding products 3a and 3b that have been manually prepared by the operator onto the conveyor 4, thereby improving the productivity. Becomes difficult.

An object of the present invention is to provide a winding device capable of simultaneously manufacturing a plurality of types of winding products and a winding method using the same.

Also, an object of the present invention is to provide a manufacturing facility and a manufacturing method of a finished product that can improve productivity by assembling a plurality of types of winding products without loss.

Including an inspection process for inspecting each product, and an assembly process for assembling a plurality of types of winding products to obtain a finished product. In the inspection process, winding products that do not satisfy the predetermined requirements are excluded and assembled. When the necessary number of winding products is insufficient in the assembly process, a shortage signal is issued, and in the winding process after the shortage signal is generated, the number of obtaining the shortage of winding products is increased.

The storage device 51 in the control means 50 has an interface for inputting and outputting a control program via a selection circuit 80 described later, and is configured to store a plurality of control programs and output the control program via the interface. The

The electric control device 52 is provided with a memory 52a for temporarily storing the control program supplied from the storage device 51. The electric control device 52 drives and stops the X, Y, and Z

axis servo motors

Configured to let In the present embodiment, a plurality of electric control devices 52 are provided corresponding to the number of the rotational drive sources 19 and the nozzle position adjusting means 25.

Since the connection structure to the rotation drive source 19 and the nozzle position adjusting means 25 (FIG. 3) in the plurality of electric control devices 52 provided is the same, one of them will be described below as a representative. The electric control device 52 includes a spindle control circuit 53 that individually controls the spindle motor 19 to rotate the spindle 13 provided with the winder 18, and a nozzle position that controls the position of the nozzle 24 a that supplies the wire 23.

Further, the spindle motor 19 is configured to stop when the number of feedback pulses generated by the encoder 21 matches the number of input control pulses. The encoder 21 is configured to emit an origin position pulse when the rotation shaft of the spindle motor 19 reaches a predetermined position during one rotation.

Thus, according to the control program stored in the memory 52a, the electric control device 52 outputs the control pulse and rotates the spindle motor 19 until the origin position pulse arrives. In addition, when the transmission of the control pulse is stopped, the electric control device 52 is configured to set the spindle 13 to the initial position by automatically stopping the spindle motor 19 when a feedback pulse comes in.

The nozzle position control circuit 54 is a circuit that controls the nozzle position adjusting means 25 (FIG. 3). The position of the nozzle 24a is controlled by

separate servo motors

29, 32a, and 33 in the vertical direction, the horizontal direction, and the front-rear direction. The position of the nozzle 24a also needs to be moved in maintenance other than normal winding work. The nozzle position control circuit 54 includes an up / down direction control circuit 55, a left / right direction control circuit 56, and a front / rear direction control circuit 57 having the same circuit configuration as the spindle control circuit 53 described above.

Further, when the transmission of the control pulse is stopped, the electric control device 52 can set the X-axis actuator 32 to the initial position by automatically stopping the Z-axis servomotor 33 due to the incoming feedback pulse. .

Similarly, the left-right direction control circuit 56 controls the Y-axis servomotor 29 that moves the movable base 27 in the Y-axis direction. The Y-axis servo motor 29 is connected to the output terminal of the electric control device 52 via the counter 70, the D / A conversion circuit 71, and the amplifier 72, and starts rotating by the control pulse of the electric control device 52. The Y-axis servo motor 29 is configured to stop when the number of feedback pulses generated by the encoder 73 provided in the Y-axis servo motor 29 coincides with the input control pulse number.

Similarly, the front-rear direction control circuit 57 controls the X-axis servo motor 32a in the X-axis actuator 32 in which the nozzle means 24 is attached to the follower 32c. The X-axis servo motor 32 a is connected to the output terminal of the electric control device 52 via the counter 74, the D / A conversion circuit 75, and the amplifier 76, and starts rotating by a control pulse of the electric control device 52.

encoders

69, 73, and 77 are configured to emit an origin position pulse when the rotation shafts of the X, Y, and

Z axis servomotors

29, 32a, and 33 reach a predetermined position during one rotation. Therefore, the electric control device 52 outputs a control pulse and rotates the X, Y, and Z

axis servo motors

29, 32a, and 33 until an origin position pulse arrives. In addition, when the electric control device 52 stops sending the control pulses, the number of feedback pulses corresponding to the number of control pulses comes in, so that the

servo motors

29, 32a,

X-axis servo motors

Further, at the output end of the electric control device 52, in order to drive the clamp 48 and the elevator 49 with fluid pressure, an electromagnetic that switches air, which is a fluid sent to the clamp 48 and the elevator 49 from the air compressor 59 through the pipe 60, is switched. Output signal lines to the

valves

61 and 62 are connected.

The control means 50 provides any of the plurality of control programs stored in the storage device 51 to any of the plurality of electric control devices 52 and stores the same in the memory 52a. The control means 50 performs the electric according to the control program stored in the memory 52a. A selection circuit 80 for driving the control device 52 is provided.

The input circuit 81 such as a keyboard is connected to the selection circuit 80, and an output end of another device can be connected to the input end. The selection circuit 80 determines which of the plurality of control programs stored in the storage device 51 is to be provided to which of the plurality of electrical control devices 52 based on output information from the input unit 81 and other devices, The electric control device 52 is configured to be driven according to the control program. That is, the selection circuit 80 determines and provides which of the control programs stored in the storage device 51 is provided to each of the plurality of electric control devices 52.

For this reason, for example, when the winding tool holders 12 are provided in an even number, the selection circuit 80 controls the control drive program 19 for each rotational drive source 19 of one group that divides the even number of winding tool holders 12 into two. And another control program can be provided to each of the rotary driving sources 19 of the other group. That is, according to the selection circuit 80, different control programs can be provided to different electric control devices 52 in the plurality of electric control devices 52. According to this, although the winding apparatus 10 is a single apparatus, it becomes possible to manufacture two types of winding products simultaneously.

Next, a winding method using the winding device 10 will be described.

In the winding device 10, a plurality of winder holders 12 are pivotally supported on a single base 11. For this reason, in the winding method by the winding device 10, the winding tool 18 is attached to each of the plurality of winding tool holders 12 and rotated, and the wire 23 is wound around the rotating winding tool 18.

First, as a preparation stage, the wire 23 is unwound from a spool (not shown) arranged behind the base 11 and passed through a tension applying portion (not shown), and then inserted into the nozzle 24a. Further, as shown in FIG. 4, the end portion of the wire 23 is sandwiched between the

wire sandwiching portions

48 a and 48 b in the clamp 48. And the coil bobbin 18 which is a winding tool which winds up the wire 23 is attached to the attachment shaft 17 of each spindle 13.

In such a preparation state, when information indicating that the winding is started after the winding condition is input from the input unit 81, the selection circuit 80 selects the windings input from the input unit 81. A plurality of control programs stored in the storage device 51 are selectively supplied to each electric control device 52 according to the conditions. Each electric control device 52 temporarily stores the control program supplied via the selection circuit 80 in the memory 52a, moves the nozzle 24a in accordance with the control program, and attaches the coil bobbin 18 to the winder holder. 12 is rotated to start winding.

In the present embodiment, the coil bobbin 18 that is a winder includes a binding pin 18d. The winding procedure in this case will be described below. As shown in FIG. 4, first, the nozzle 24a is wound around the tangling pin 18d, and the wire 23 extending from the nozzle 24a to the clamp 48 is wound around the tangling pin 18d to obtain the wire rod 23a at the beginning of winding. After that, the elevator 49 (FIG. 3) ties the clamp 48 away from the pin 18d, ties the wire 23 in the vicinity of the pin 18d, and shreds the wire 23a in the vicinity of the pin 18d, leaving the wire 23a at the beginning of the winding on the pin 18d.

In this state, according to the control program that is selectively supplied from the storage device 51 shown in FIG. 1 by the selection circuit 80 and temporarily stored in the memory 52a, the electric control device 52, together with the coil bobbin 18, each winder holder 12 Rotate. Thereby, as shown in FIG. 5, the wire 23 fed from the nozzle 24 a is wound around the winding body portion 18 a of the coil bobbin 18.

That is, the spindle control circuit 53 starts to operate in accordance with a control program selectively supplied from the selection circuit 80 and temporarily stored in the memory 52a, and the winding is performed by driving the spindle motor 19 and rotating the coil bobbin 18. Is made. Here, when each spindle motor 19 operates, the coil bobbin 18 rotates by the number determined in the control program, and the wire rod 23 fed out from the nozzle 24a is wound around the coil bobbin 18 by the number of rotations.

Along with the winding of the wire rod 23, the electric control device 52 moves the nozzle means 24 that feeds the wire rod 23 in accordance with a control program temporarily stored in the memory 52a. Thereby, the winding position of the wire 23 is adjusted. That is, the vertical position direction control circuit 82 controls the distance between the outer periphery of the wire 23 wound around the coil bobbin 18 and the tip of the nozzle 24a to a predetermined position. The position of the nozzle 24 a is controlled by the left-right direction control circuit 56 corresponding to the winding layer of the wire 23. Further, the position of the nozzle 24 a is controlled by the front-rear direction control circuit 57 in accordance with the number of turns of the wire 23.

When the wire 23 is wound around the coil bobbin 18 a desired number of times, the nozzle 24a is moved by the nozzle position adjusting means 25 according to the control program provided through the selection circuit 80, as shown in FIG. Is rotated around another tangle pin 18d of each coil bobbin 18. As a result, the wire 23 extending from the nozzle 24a is entangled with the pin 18d to form the wire end wire 23b.

Further, according to the control program, the wire 23 extending from the binding pin 18d to the nozzle 24a is sandwiched between the wire sandwiching portions 48a of the clamp 48. Thereafter, the elevator 49 (FIG. 3) causes the clamp 48 to be separated from the pin 18d and the wire 23 to be tangled and shredded in the vicinity of the pin 18d to leave the winding end wire 23b on the pin 18d. Thereby, a series of winding operations are completed.

Here, in the winding method using the winding device 10, each electric control device 52 controls the plurality of winder holders 12 and the nozzle position adjusting means 25 to perform winding. Therefore, if the control program supplied from the selection circuit 80 is the same, the same winding can be performed to obtain the same winding product, and the control program supplied from the selection circuit 80 is different. Then, another winding is performed.

Therefore, in the winding method according to the present embodiment, the plurality of winder holders 12 are divided into a plurality of groups, and the control provided to the electric control device 52 that controls the winder holders 12 belonging to each group. Different programs for each group. As a result, the plurality of winder holders 12 are rotated independently for each group. Further, the tip of the nozzle means 24 is also moved independently for each group together with the rotation of the winder holder 12 in each group. That is, the plurality of winder holders 12 and the corresponding nozzle means 24 (supplying the wire 23) are operated independently under different conditions for each group. Thereby, a plurality of types of winding products are obtained simultaneously.

In this embodiment, since the four winder holders 12 are provided, the even-number winder holders 12 are divided into two groups. One control program is supplied to each electric control device 52 that controls the winder holder 12 and the nozzle position adjusting means 25 of one group. Another control program is supplied to each electric control device 52 that controls the winder holder 12 and the nozzle position adjusting means 25 of the other group. In this way, by rotating the winder holders 12 in one group and the other group separately and independently, the same number of two types of winding products can be manufactured simultaneously.

4 to 6, a coil bobbin 18 as a winding tool is provided with a tangled pin 18d, and two types of winding products B and C (FIG. 6) around which a wire 23 is wound are shown. The case where the same number is manufactured simultaneously is shown.

That is, in the embodiment shown in FIGS. 4 to 6, the coil bobbin 18 attached to two of the four winding tool holders 12 has two binding pins provided on the flange 18b on one side thereof. A winding product B is produced in which the winding wire 23a and the winding wire 23b are wound around 18d. Further, the coil bobbin 18 attached to the other two winder holders 12 is wound with the wire rod 23a at the beginning of winding on the binding pin 18d provided on the flange 18c on one side, and the other flange 18b. The winding product C in which the winding end wire 18b is entangled with the binding pin 18d provided on the winding product B is manufactured simultaneously with the winding product B.

As described above, in the winding method using the winding device 10, the rotational speed of the coil bobbin 18 as a winding tool and the movement of the nozzle 24 a are determined by a control program provided via the selection circuit 80. Specifically, in the winding method according to the present embodiment, the plurality of winder holders 12 are divided into a plurality of groups, and the plurality of winder holders 12 are separately and independently provided for each group. Rotate. For this reason, although it is the single coil | winding apparatus 10, multiple types of coil | winding products B and C can be manufactured simultaneously.

In particular, the tip of the nozzle means 24 for supplying the wire 23 to be wound around the winder 18 which is disposed with the tip facing the winder 18 and rotates is also provided on the winder holder 12 in each group. With rotation, each group is moved separately and independently. Thus, not only the number of windings of the wire 23 but also the drawing position of the wire 23 can be made different for each type of the winding products B and C.

Next, the manufacturing equipment 100 including the winding device 10 will be described.

As described above, the winding device 10 can simultaneously manufacture a plurality of types of winding products B and C, and a manufacturing facility 100 including the winding device 10 is wound by the winding device 10 as shown in FIG.

And an assembly machine 130 that is provided downstream of the inspection machine 120 and assembles a plurality of types of winding products B and C.

In the inspection machine 120, before the winding products B and C conveyed from the winding device 10 by the conveyor 110 are assembled by the assembling machine 130, the winding products B and C are wound according to a desired specification. Inspect whether or not the prescribed requirements are satisfied. Thereby, generation | occurrence | production of inferior goods is prevented beforehand. Specifically, in the inspection machine 120, the winding products B and C that do not satisfy the predetermined requirements as a result of the inspection are excluded from the winding machines B and C that do not satisfy the requirements. Exclusion means 121 is provided to prohibit further downstream transport. The exclusion means 121 in the figure is a robot having a gripping part 121a for gripping defective products.

The assembling machine 130 assembles a plurality of types of winding products B and C to obtain a finished product. In the assembly machine 130, since the winding products B and C may be excluded in the inspection machine 120 in the previous process, a detector that detects the conveyance state of the winding products B and C conveyed by the conveyance device 110. 131 is provided. For this reason, the assembling machine 130 is configured to assemble a plurality of types of winding products B and C whose conveyance state has been confirmed by the detector 131.
