Description

Long material feeding device, coil winding device, and material bobbin installation method

The present invention relates to a long material feeding device, a coil winding device, and a material bobbin installation method. More specifically, the present invention relates to a long material feeding device and a coil that can easily and efficiently continuously feed a long material such as a rectangular wire. The present invention relates to a winding device and a material bobbin installation method.

A bobbin is often used to continuously feed a long material such as a wire. A long material is wound around the bobbin, and the long material is fed out by rotating the bobbin.
For example, a bobbin drum delivery stand that rotates a bobbin drum installed at a bobbin drum delivery stand position and feeds a wire wound around the bobbin drum is known (for example, see Patent Document 1).

In the apparatus disclosed in Patent Document 1, first, the bobbin drum is transported to the table position of the bobbin drum delivery stand by the transport conveyor and then placed on the pallet support plate. Then, the pallet support plate is lifted by a lift.
Thereafter, the two supporting rolls that are arranged opposite to each other and moved backward are moved forward by the cylinder to support the winding drum of the bobbin drum from below, and the lift is lowered. The two support rolls are rotatable.
The wire is fed out by driving one of the two support rolls and rotating the bobbin drum.

Will be. The weight of the bobbin drum on which the wire is wound is considerable, and the load applied to the two support rolls is naturally large.
As a result, depending on the material of the wound wire, the wire may be deformed. For example, most of the above-mentioned rectangular wires are copper products, and when a rectangular wire is wound around a bobbin drum, there is a problem that the soft rectangular wire is deformed due to the weight of the bobbin drum. Further, since the wire is drawn out from the state pressed by the two support rolls, there is a problem that the enamel or the like attached to the surface of the rectangular wire is peeled off due to friction at that time.

Furthermore, in the bobbin drum delivery stand disclosed in the above-mentioned Patent Document 1, a transport conveyor that transports the bobbin drum to the stand position, a lift mechanism that raises the bobbin drum, two support rolls that support the bobbin drum, and these support rolls Two cylinders that move back and forth, a presser roll that stabilizes the bobbin drum, and the like are required.

It is provided at an angle α. Here, when the inclination angle is steep, a large amount of labor is required to load the mounting plate 21. When the angle is too gentle, the length of the guide member 65 becomes long, and the installation space and material cost increase. .
A plurality of (six in this embodiment) legs 61 are equally arranged on the bottom plate 24, and the height of each leg 61 can be adjusted.

Next, a material feeding method of the flat wire W by the long material feeding device as described above will be described based on the flowchart of FIG.
First, as the first step (ST1), the lifter mechanism 42 is driven, the rotary driven shaft 36 is moved downward to be lowered to the initial position, and the material bobbin 10 is brought into a standby state.

Next, as a second step (ST2), when the introduction waiting state of the material bobbin 10 is confirmed, the operator loads (rolls) the material bobbin 10 from the tip of the guide member 65. It is carried on the mounting plate 21 and mounted on the mounting plate 21.
At this time, the material bobbin 10 is carried onto the placement plate 21 from the inclined upper surface portion 65 </ b> A of the guide member 65 via the upper end of the rotation driven shaft 36. Further, both outer ring portions 12 of the material bobbin 10 are in contact with the upper surface of the mounting plate 21 and are also in contact with the rotation drive shaft 26.

Next, as a third step (ST3), the lifter mechanism 42 is driven to lift the lifter nut 39, the support plate 38, the rotary driven shaft 36, and the like, and both the outer ring portions 12 of the material bobbin 10 are placed on the mounting plate 21. Floating from the top of the.
At this time, when the rotation drive motor 52 is first driven, the rotational force is transmitted from the second lift sprockets 44, 44 to the first lift sprockets 50, 50 via the chain 49, and this first lift sprocket. The lifter shaft 40 is rotated by the rotation of 50 and 50.

As a result, the lifter nut 39 screwed to the lifter shaft 40 is lifted, the support plate 38 connected to the lifter nut 39 is lifted, and the rotary driven shaft 36 supported by the support plate 38 is lifted.
As the rotary driven shaft 36 rises, the rotary driven shaft 36 and the outer ring portions 12 of the material bobbin 10 placed on the placement plate 21 come into contact with each other.
By further raising the rotary driven shaft 36, both outer ring portions 12 of the material bobbin 10 are pushed up, and both outer ring portions 12 of the material bobbin 10 are lifted from the upper surface of the mounting plate 21. And when it raises by the dimension L + L1 mentioned above, the position is the state set to the optimal position which can pay out the flat wire W.
At this time, the dog 60 fixed to the lifter nut 39 is detected by the lifter upper position sensor 57A, whereby the lift of the lifter nut 39 is stopped.

According to the first embodiment as described above, the following effects can be obtained.
(1) Both the outer ring portions 12 of the material bobbin 10 placed on the bobbin support device 20 are supported and rotated by the rotation drive shaft 26 and the rotation driven shaft 36 from the upper surface of the placement plate 21. By driving the drive shaft 26 and rotating both the outer ring portions 12 of the material bobbin 10, the rectangular wire W can be drawn out. As a result, the contact between the outer ring portions 12 of the material bobbin 10 and the upper surface of the mounting plate 21 is eliminated, and the frictional portion is reduced. Therefore, the material bobbin 10 can be easily rotated and the rectangular wire W is deformed. It can be fed out without causing damage to the surface and the flat wire W can be fed out with a simple configuration.

(2) A first sprocket 31 and a second sprocket 33 are provided in parallel with one plate-like bearing mechanism 28, and a feeding motor 34 is provided on the back surface of the bearing mechanism 28. Since one sprocket 31 is mounted on the rotary drive shaft 26, the configuration of the rotation transmission mechanism 30 can be compactly assembled.

(3) Since the lifter shaft 40 is formed of a trapezoidal screw, and the lifter nut 39 is screwed to the lifter shaft 40, the lifter shaft 40 can move up and down. Can be done accurately. Even if the motor 34 is stopped and the rotational driving force via the rotation transmission mechanism 30 is released, the material bobbin 10 and the rotary driven shaft 36 are lowered by their own weight due to the friction of the screw surface of the trapezoidal screw portion. Never do.

(4) If the lift 60 of the lifter nut 39 detects the dog 60 fixed to the lifter nut 39 by the lifter lower position sensor 58A attached to the storage box 43, the material bobbin 10 is loaded. It may be guided and placed on the placing plate 21. When the dog 60 is detected by the lifter upper position sensor 57A, the rotary driven shaft 36 lifts the outer ring portions 12 to the maximum, that is, the rectangular wire W. Is determined to be possible. When the dog 60 is detected by the upper lifter overrun sensor 57B and the lower lifter overrun sensor 58B, it is determined that the upper position sensor 57A or the lower position sensor 58A is poorly detected or the motor 52 is poorly controlled. The drive power is cut off and a trouble alarm is issued to prevent the lifter nut 39 from colliding with the first sprocket 44 mounted on the back surface of the upper plate 43C of the storage box 43 or the lower part of the lifter shaft 40. For this reason, abnormal feeding of the flat wire W can be prevented.

(5) The guide member 65 has an inclined upper surface portion 65A whose front end portion is grounded to the floor surface FL and whose rear end portion is positioned on the extension of the mounting plate 21 and whose height is the upper surface of the mounting plate 21. Have. Since the inclination angle α of the inclined upper surface portion 65A is set to 15 degrees, for example, when the material bobbin 10 is placed on the placement plate 21 from a predetermined location, a large force is required by the operator rolling it. It can be easily transported and set at a predetermined position. Therefore, there is no need for a large lifting device such as a crane.
