Description

[Detailed description of the invention] [Background and purpose of the invention] The present invention relates to a winding device.

FIG. 2 shows a conventional example of a winding device.
As shown in the figure, this device includes a rotating flange 1, a bobbin 2 having a hollow hole located adjacent to the rotating flange 1, and a winding shaft 3 inserted into the hollow hole of the bobbin 2. In this device, a bobbin 2 is passed through a take-up shaft (reel shaft) 3, and rotation is transmitted by a pin 4 on one surface of a rotating flange, and on the other side, the bobbin 2 is clamped and fixed using a flange or a taper collar 5 with screws. Then, the bobbin 2 is rotated by the rotation of the rotating flange 1, and the electric wire is wound onto the bobbin 2. However, with this device, in addition to the bobbin 2, the taper collar 5, tightening nut 6, etc. must be set in 2 to 3 stages in order to install the bobbin 2, which is cumbersome, and in order to remove the bobbin 2, it is necessary to wind a fully wound bobbin. It has to be pulled out from the take-up shaft 3, resulting in poor workability.

FIG. 3 shows another conventional example of a winding device. As shown in the figure, this device includes a rotating flange 1, a bobbin 2 having a hollow hole arranged adjacent to the rotating flange 1, and a bobbin 2 fixed to the rotating flange 1 through the hollow hole of the bobbin 2. It is equipped with an extract banding arbor shaft body 7, etc. In the figure, 8 is a spring, 9 is an expel, and 10 is a shoe. In this device, the hollow hole of the bobbin 2 is tightened and fixed by the extract banding arbor shaft body 7. That is, the EXPEL 9 is moved in the direction of the arrow in the figure and tightened and fixed. By the way, in this device, although the bobbin 2 is easy to install and has good workability in attaching and removing, the structure of the arbor shaft body 7 itself is complicated and expensive.

FIG. 4 shows still another conventional example of a winding device. As shown in the figure, this device is equipped with a rotating flange 1, a bobbin 2, a take-up shaft (reel shaft) 3, etc. Taper collars 5 are used at both ends of the bobbin 2, and are tightened with screws to transmit rotation and fix the device. It is something to do. However, the threaded portion of this device is tightened during rotation, and when removed, the screw becomes tight and difficult to remove. In addition, it is troublesome to have to turn the screw many times, and the reel shaft 3
In order to pass the bobbin 2 through the bobbin, it is necessary to remove the bobbin 2 to remove the fully wound bobbin, which is poor work efficiency.

FIG. 5 shows still another conventional example of a winding device. As shown in the figure, this device includes a rotating flange 1, a bobbin 2, a spring 8a, a bobbin fixing shaft 11, a handle 12, etc., a bobbin 2 is placed on the surface of the rotating flange 1, and a hollow hole of the bobbin 2 and The bobbin fixing shaft 11 is passed through an insertion hole provided in the rotating flange 1 and screwed to fix the bobbin 2. A pin 4 for transmitting rotation to the bobbin 2 is attached to the rotating flange 1 (however, there is also one that does not use the pin 4 and transmits the rotation by the tightening force of the screw of the bobbin fixing shaft 11).
Similar to the case shown in FIG. 4, this device has to be turned many times to tighten the screw, and the screw portion is tightened during rotation and cannot be removed, resulting in poor workability.

The present invention has been made in view of the above points,
It is an object of the present invention to provide a winding device that allows easy attachment and detachment of a bobbin to a rotating flange.

A lock pin is buried in a part of the periphery of the bobbin fixing shaft, and a plurality of pin grooves into which the lock pins are inserted are provided in a part of the outer periphery of the bobbin fixing shaft in the axial direction, and the bobbin fixing shaft is inserted and rotated, and the lock pin is inserted into the bobbin fixing shaft. The bobbin fixing shaft is fixed to the rotating flange by fitting into the pin groove, whereby an insertion hole into which the bobbin fixing shaft is inserted is formed in the center of the rotating flange. A lock pin is embedded in a part of the periphery of the insertion hole, and a plurality of pin grooves into which the lock pins are inserted are provided in a part of the outer periphery of the bobbin fixing shaft in the axial direction,
When the bobbin fixing shaft is inserted and rotated, the bobbin fixing shaft is fixed to the rotating flange by fitting between the lock pin and the pin groove.

[Example] The present invention will be described below based on the illustrated example. FIG. 1 shows an embodiment of the invention. Note that parts that are the same as those in the conventional system are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, the rotating flange 1
An insertion hole into which the bobbin fixing shaft 11 is inserted is provided at the center, and a lock pin 13 is embedded in a part of the periphery of this insertion hole, and the lock pin 13 is inserted into a part of the outer periphery of the bobbin fixing shaft 11. A plurality of grooves 14 are provided in the axial direction, the bobbin fixing shaft 11 is inserted and rotated, and the lock pin 13 and the pin groove 14 are fitted to lock the bobbin fixing shaft 1.
1 is fixed to the rotating flange 1. By doing this, an insertion hole into which the bobbin fixing shaft 11 is inserted is provided at the center of the rotating flange 1, and a lock pin 13 is embedded in a part of the periphery of this insertion hole, and the bobbin fixing shaft 1
A plurality of pin grooves 14 into which lock pins 13 are fitted are provided in a part of the outer periphery of the lock pin 1 in the axial direction. Then, when the bobbin fixing shaft 11 is inserted and rotated, the bobbin fixing shaft 11 is fixed to the rotating flange 1 by the engagement between the lock pin 13 and the pin groove 14, and the bobbin 2 can be attached to and removed from the rotating flange 1. It is possible to obtain a winding device that makes it possible to easily perform the following steps.

That is, the bobbin fixing shaft 11 is inserted and rotated, and the lock pin 13 and the pin groove 14 fit together to fix the bobbin fixing shaft 11 to the rotating flange. A taper collar 5 and a spring 8a were provided. By doing this,
Not only is it easy to attach and fix the bobbin 2 to the rotating flange 1, but it is also easy to remove it. That is, the bobbin 2 is set on the rotating flange 1, the bobbin fixing shaft 1 is inserted, and the pin groove 14 provided in the bobbin fixing shaft 11 is aligned with the lock pin 13 provided in the insertion hole of the rotating flange 1. Fix the bobbin 2 to the rotating flange 1 by turning it 90 degrees in the cutting direction (cutting in the opposite direction to the winding direction). A taper collar 5 and a spring 8a are attached to the bobbin fixing shaft 11 so that the bobbin 2 can be adjusted or centered according to the diameter and height of the hollow hole of the bobbin 2. The rotation of the bobbin 2 is transmitted by the pin 4 on the rotating flange 1, and the longitudinal direction of the bobbin 2 is held down by a bobbin fixing shaft 11. Several pin grooves 14 are provided in the bobbin fixing shaft 11 according to the type of bobbin 2, so that several types of bobbins 2 can be fixed using the same bobbin fixing shaft 11. The bobbins 2 shown in the same figure are PT25 (25Kg taper bobbin) and PT60 (60Kg taper bobbin).
It is a bobbin.

After setting the bobbin 2 by aligning it with the pin 4 on the rotating flange 1, insert the bobbin fixing shaft 11 into the insertion hole provided in the rotating flange 1, or insert the lock pin 13 and the bobbin according to the height of the bobbin 2. Gently push the bobbin fixed shaft 11 until it lines up with the pin groove 14 on the fixed shaft 1.
Rotate 90°. The pin groove 14 has a somewhat ragged shape so that the lock pin 13 can be guided into the pin groove 14 even if it is slightly misaligned. Further, the spring 8a is used to absorb errors in the height of the bobbin 2 and to ensure a pressing force to keep the bobbin 2 fixed, and the taper collar 5 is used to adjust the center position of the bobbin 2 with respect to the diameter of the hollow hole of the bobbin 2. A taper is provided at the tip so that it can be adjusted to match the size of the hole. The anti-rotation pin 15 also serves as a slide guide for the tapered collar 5 in the vertical direction, but may be omitted. In order to set the pressing force of the bobbin 2 according to the type of bobbin 2 and the winding tension, the amount of slide of the taper collar 5 and the size of the spring system of the spring 8a are determined within a certain range for the type of bobbin 2. There is a need. Accordingly, bobbin fixing shaft 11, lock pin 1
3 and the dimensions of the pin groove 14.

By doing so, the bobbin 2 is pressed and fixed to the rotating flange 1 side by the force of the spring 8a via the taper collar 5. After full winding, the bobbin 2 can be released by turning the bobbin fixing shaft 11 90 degrees in the opposite direction, removing the pin groove 14 of the bobbin fixing shaft 11 from the lock pin 13, and pulling it out. This allows the bobbin 2 to be attached and removed easily. Since the bobbin fixing shaft 11 is lifted by a person, it is lightweight and easy to handle. In this way, according to this embodiment, not only is it easy to attach and detach the bobbin 2 to the rotating flange 1, but also the bobbin fixing shaft 1
Since only 1 has to be operated, the structure is simple and the workability is good.

Note that the spring 8a built into the taper collar 5 may be attached to the rotating flange 1 side, and the taper collar 5 may be made into a fixed collar and fixed to the bobbin fixing shaft 11. By doing so, the force for tightening the bobbin 2 is generated by the spring 8a provided on the rotating flange 1 side, and errors in the height dimension of the bobbin 2 can be similarly absorbed.

Furthermore, in this embodiment, the bobbin fixing shaft 11 is rotated in the opposite direction to the rotating direction of the rotary flange 1 to lock it, but the pin groove 14 into which the lock pin 13 is fitted is also provided in the opposite direction, so that it can be rotated in both directions. The bobbin fixing shaft 11 may be rotated to lock it.

Further, it can be used not only in a vertical type as in this embodiment but also in a horizontal type.

[Effects of the Invention] As described above, the present invention can provide a winding device in which the bobbin can be easily attached and detached from the rotating flange, and the bobbin can be easily attached and detached from the rotating flange.
