Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is an automatic winding system that continuously performs a winding process and a winding finishing process in which a finished coil bobbin is finished. The present invention relates to processing equipment, and in particular to a winding and winding finishing automatic continuous processing equipment in which the holding interval of the coil bobbin during the winding finishing process is reduced in order to improve the efficiency of winding finishing and reduce the area occupied by the equipment.

(Prior art) Conventionally, in this type of processing, the winding and winding finishing processes were performed in separate operations, including loading the coil bobbin onto the winding machine, removing it after the winding work was completed, and finishing the winding. Attachment and removal to and from each device are carried out by a worker or by a dedicated machine. Furthermore, a conveyor or the like is often used to transport the coil bobbin between the winding machine and each group of winding finishing devices.

(Problems to be Solved by the Invention) In recent years, winding work as well as winding finishing work has been automated, and there are some machines in which the feeding and discharging of coil bobbins is also performed by dedicated machines for each device that handles these processes.

Furthermore, there are some devices in which the arrangement of devices for the winding finishing process is devised to reduce the area occupied by the winding finishing process.

However, a conveyor or other bobbin transporting device is required to transport the coil bobbin that has been wound using a winding machine to the location where the first winding process takes place.
Since the coil bobbin is supplied to and discharged from the winding machine and winding finishing devices using a dedicated machine, a large area is required.

To solve this problem, the coil bobbin can be held and reciprocated in a straight line, stopped at a predetermined position, and delivered to the winding machine before and after winding work, or the bobbin can be moved while holding the bobbin to finish the winding. One possible method is to provide two coil bobbin conveying devices (hereinafter referred to as shuttles) that perform continuous processing. However, in this method, the distance between the shuttles for winding the coil bobbin and the rotating spindle must be the same as the distance between the winding machine and the rotating spindle holding the coil bobbin for winding.

On the other hand, the spacing between the coil bobbins held by the shuttle for the winding finishing process should be equal to the coil bobbin spacing required for soldering, cleaning, drying, and checking the continuity of the winding coil bobbin terminals. good. However, all these spacings are much narrower than the spindle spacing of the winding machine.

Therefore, if the coil bobbins held therein are transferred from the shuttle for winding work to the shuttle for winding finishing process while maintaining the same spacing, there is a problem that the efficiency of the winding work is extremely poor.

The purpose of the present invention is to solve these problems,
When the coil bobbins are transferred from the winding process shuttle to the winding finishing process shuttle, the distance between the coil bobbins is narrowed, thereby making it easy to downsize each device for the winding finishing process. The purpose of the present invention is to provide a continuous automatic processing device for winding finishing.

Therefore, the area occupied by the entire device is much smaller than before, and the layout for each device is also easier, allowing for continuous automatic processing of winding and winding finishing that improves product quality and reduces work time. The goal is to provide a method.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the continuous automatic processing device for winding and winding finishing of the present invention has a winding device 4 and a plurality of coil bobbins 2, 2...2. The first shuttle 10 that transfers and receives wires, and each winding finishing process device 70, 72, which moves the coil bobbins 2, 2...2 that have already been wound, performs each winding finishing process.
Second shuttle 20 with 74, 76, 78
, the first shuttle 10, the second shuttle 20, the winding device 4, and each device 70, 7 for the winding finishing process.
It has an electronic control device that synchronizes and controls the operations of 2, 74, 76, and 78.

The first shuttle 10 is the coil bobbin 2, 2...
2, the interval at which the second shuttle 20 holds the coil bobbins 2, 2, .

The electronic control device is configured by a programmed microcomputer, and controls the operation of transferring the coil bobbins 2, 2...2 from the first shuttle 10 to the second shuttle 20.
From among the coil bobbin groups held in a row at 0, the coil holding portions to be transferred are placed opposite each other at regular intervals to transfer the coils, and after the previous transfer, the first shuttle 10 and the first shuttle 10 The electronic control device controls the transfer of all wound coil bobbins 2, 2, .

Note that the coil bobbin is not shown in FIGS. 2 to 6 because it would be complicated.

First, the basic arrangement of this embodiment will be explained.

As shown in FIG. 2, in this embodiment, a parts feeder 1 supplies a coil bobbin 2 to the finger unit 11, and a parts feeder 1 faces a shuttle 10 that horizontally moves a finger unit 11 holding a coil bobbin 2, and a parts feeder 1 receives the coil bobbin from the finger unit 11. A main body of a winding machine 4 for winding the wire is arranged.

In addition, 3 is a spindle for rotating the coil bobbin 2 attached to the main body of the winding machine 4 to perform winding, and 5 is a spindle for winding the coil bobbin 2 attached to the spindle 3, or after winding is completed. This mechanism moves the nozzles that guide the winding all at once when the terminal is connected to the terminal.

In addition, the coil bobbins 2 and 2 of the parts feeder 1
The outlet for discharging and supplying the coil bobbin 2 is arranged at a position facing the pin into which the coil bobbin 2 is to be inserted with the finger unit 11 facing downward. Further, the spindles 3, 3...3 are positioned so that the coil bobbins 2, 2...2 can be delivered to the winding machine 4 when the finger unit 11 is in a horizontal position (indicated by the two-dot chain line in FIG. 1). It is located in

On the other hand, facing the shuttle 20 that horizontally moves the finger unit 21 holding the coil bobbin, there is a soldering process apparatus 70 having a solder bath 71 for soldering the terminals of the coil bobbin 2 that has already been wound, and , a cleaning machine 72 having a cleaning tank 73 containing a cleaning liquid to remove impurities attached during soldering, a hot air blower 74 having a hot air outlet 75 that blows out hot air for drying after cleaning, and a hot air blower 74 for cleaning windings. A defective product sorter 76 having a sensor section 77 for conducting a continuity test, etc., and a defective product discharging mechanism 78 for discharging the defective products into a case 79 for storing the defective products are arranged in a line. Note 8
0 is a conveyance device that conveys pallets 81 that receive finished products in line.

Further, the solder tank 71, the cleaning tank 73, the hot air outlet 75, and the defective product discharge mechanism 78 are arranged in a straight line facing the coil bobbins 2, 2...2 when the finger unit 21 moves downward. .

This device is equipped with an electronic control device (not shown) configured by a programmed microcomputer, which controls the winding machine 4, shuttle 10, shuttle 20, and each device for the winding finishing process (for the soldering process). Device 70, washing machine 72, hot air machine 7
4. The operations of the defective product sorting machine 76 and the defective product removal mechanism 78) are all controlled in synchronization according to the program.

Next, the drive mechanism for the finger units 11 and 21 will be explained. As shown in Figure 1, the first
A moving plate 12 having an internal thread is fixed to a finger unit 11 of a shuttle 10 and is fitted into a ball screw 13. When the ball screw 13 is rotated by the motor 14 via the shaft coupling 15, the movable plate 12 moves horizontally as shown by the arrow in the figure, and the finger unit 11 also moves above the linear guide rail 16. can be moved horizontally.

Similarly, a moving plate 22 with an internal thread is fixed to the finger unit 21 of the second shuttle 20.
is fitted into the pole screw 23. Therefore, when the pole screw 23 is rotated by the motor 24 via the shaft coupling 25, the moving plate 2
Since the finger unit 2 moves horizontally as shown by the arrow in the figure, the finger unit 21 can also be moved horizontally along the linear guide rail 26.

Finger unit 11 of first shuttle 10
is fixed to the rotating shaft 32 by shaft mounting blocks 33, 33, as shown in FIGS. 2 and 3. The rotating shaft 32 is a ball bearing 3
5 and 35, it is rotatably supported by a moving table 47 that can move horizontally on the linear guide rail 16. Note that the moving table 47 is movably supported on the linear guide rail 16 by a linear guide 48.

On the other hand, the rotating shaft 32 is coupled to the rotary actuator 30 via a shaft coupling 31. By driving the rotary actuator 30, the bobbin insertion pin 6 that holds the coil bobbin is inserted.
The orientation of the bobbin can be changed from sideways (the central axis of the bobbin being held is horizontal) to downward (the central axis of the bobbin being held is vertical) by rotating it 90 degrees. You can also turn it horizontally.

Similarly, the finger unit 21 of the second shuttle 20 is secured to the rotating shaft 52 by shaft mounting blocks 53, 53, as shown in FIGS. 4 and 5. The rotating shaft 52 is rotatably supported by ball bearings 55, 55 on a moving table (not shown) that can move horizontally on the linear guide rail 26.

On the other hand, the rotating shaft 52 is coupled to the rotary actuator 50 via a shaft coupling 51.

Therefore, by driving the rotary actuator 50, the direction of the bobbin insertion pin 7 that holds the coil bobbin is changed from sideways (the center axis of the bobbin being held is horizontal) to downward (the center axis of the bobbin being held is vertical). It can be changed by rotating 90 degrees to
Further, the direction of the bobbin insertion pin 7 can also be changed from downward to sideways.

Next, the structure and operation for advancing and retracting the bobbin insertion plates 6 and 7 and the bobbin removal plates 42 and 62 attached to the finger unit 11 or 21 will be explained.

As shown in FIGS. 2 and 3, the bobbin insertion pin 6 is attached to a pin mount 38 that moves together with a linear guide 36 that freely moves along a linear guide rail 37 attached to a finger board 34. It can be replaced depending on the size and shape of the coil bobbin being handled. Pin mounting base 3
8 is connected to the movable part of the air cylinder 40 via a pin mount drive plate 39. Since the air cylinder 40 is fixed to the finger board 34, the operation of the air cylinder 40 causes the pin mounting base 38 and therefore the bobbin insertion pin 6 to move forward in the direction of the central axis of the coil bobbin held by the pin, or It can be pushed back.

Further, as shown in FIGS. 2 and 3, the bobbin removal plate 42 is connected to the pin mounting base 38 via a linear guide 44 and a linear guide rail 43 so as to be freely movable along the linear guide rail 43. On the other hand, the bobbin removal plate 42 is connected to a movable block of a thin air cylinder 46 via a bobbin removal plate drive plate 45. Air cylinder 4
6 is fixed to the pin mount 38, so
By operating the air cylinder 46, the bobbin removal plate 42 can be moved forward or backward relative to the bobbin insertion pin 6.

Similarly, the bobbin insertion pin 7 is
As shown in the figure, a pin mounting plate 58 is fixed to a pin mounting plate driving plate 59 that moves in unison with a linear guide rail 56 that freely moves along a linear guide rail 57 mounted on a finger board 54.
The size of the coil bobbin that is installed and handled in
It can be replaced depending on the shape etc.

The pin mounting plate 58 is connected to the pin mounting plate driving plate 59.
It is coupled to the movable part of the air cylinder 60 via. Since the air cylinder 60 is fixed to the finger substrate 54, the operation of the air cylinder 60 allows the bobbin insertion pin 7 to move forward or backward in the direction of the central axis of the coil bobbin held by the pin.

Further, the bobbin exclusion plate 62 is shown in FIGS. 4 and 5.
As shown in the figure, it is connected to the pin mounting plate 58 via a linear guide 64 and a linear guide rail 63 so as to be freely movable along the linear guide rail 63. Further, a thin air cylinder 66 is fixed on the bobbin removal driving plate 65, and its movable part is a rising part 67 of the pin mounting plate driving plate 59.
Fixed.

Therefore, by operating the air cylinder 66, the bobbin removal plate 62 can be moved forward or backward relative to the bobbin insertion pin 7.

Next, a method of transferring the coil bobbin from the shuttle 10 to the shuttle 20 will be described.

FIG. 7 is a perspective external view of the coil bobbin 2 shown in FIGS. 1 and 8, but there are many other types of coil bobbins with different shapes and sizes that can be used in this embodiment. When transferring individual coil bobbins 2 that have been wound onto such coil bobbins from the finger unit 11 of the first shuttle 10 to the finger unit 21 of the second shuttle 20, the method shown in FIG. 8 is used. It will be held in

FIG. 8a shows that the finger unit 11 holding the coil bobbin 2 horizontally after winding has moved in front of the finger unit 21, and the center line of the bobbin insertion pin 6 is just now on the coil bobbin 2.
The figure shows a state in which the bobbin is stopped at a position that coincides with the center line of the bobbin insertion pin 7 that should receive the bobbin. From this state, the bobbin insertion pin 6 and the bobbin removal plate 42 are moved forward together, and the front ends of the bobbin insertion pin 6 and the bobbin insertion pin 7 are brought very close to each other, as shown in FIG.

Next, as shown in Figure c, by advancing only the bobbin removal plate 42, the bobbin insertion pin 6
The coil bobbin 2 held by the coil bobbin 2 is transferred to and held by the bobbin insertion pin 7. Thereafter, the bobbin removal plate 42 and the bobbin insertion pin 6 move back and return to the initial state. Note that each of the bobbin insertion pins 6 and 7 shown in FIGS. 4, 6, and 8 is provided with a crack 41 or 61 to prevent the coil bobbin 2 from falling when the pin is facing downward. However, if the coil bobbin is small and lightweight, even if the pin itself is rigid and has no cracks, changing the shape of the pin can utilize the elasticity of the inner wall of the coil bobbin hole to sufficiently prevent it from falling. can.

On the other hand, the bobbin insertion pins 6, 6, .
The coil bobbins 2, 2, 2 held by any one of the coil bobbins 42d can be sent out all at once.

Therefore, in the state shown in FIG. 1a, the three coil bobbins 2, 2, 2 of the first group can be transferred all at once from the finger unit 11 to the finger unit 21 by the method explained in FIG.

By making the second shuttle for the winding finishing process much narrower than the first shuttle that transfers the coil bobbin to and from the winding machine, each device for the winding finishing process The winding equipment and winding finishing equipment can be installed in an extremely narrow space, since there is no need to install a special machine for transferring coil bobbins, and each equipment can be placed close together. This has the effect of being able to be arranged all at once.

Additionally, work that is restricted by the structure of soldering tanks, cleaning tanks, etc. can be processed at the same time, greatly contributing to streamlining production by reducing work time.
