Description

[Detailed description of the invention] The present invention relates to a wire coil end binding machine that mutually binds the winding start end and winding end of a wire rod coil wound on a winding bobbin on a winding machine. .

The present applicant captures the starting end of a wire rod to be wound on a winding bobbin in a catching claw of a catching plate that rotates together with the winding bobbin, and captures the ending end of the wire rod in the same catching claw after the wire is fully wound. It has been proposed to facilitate transportation and storage of the wire coil by fixing the intersection of the winding start end and winding end end to each other by appropriate means. In this way, the intersection between the starting end and the ending end of the wire coil can be fixed by welding or welding, but welding or welding has the risk of causing heat damage to the wire coil, so be careful when working. It must be made.

An object of the present invention is to provide a wire coil end tying machine that can easily bind and fix wire ends without causing thermal damage to the wire coil.

Embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 3 show a wire coil end binding machine 10 according to the present invention, and this end binding machine is a wire winding machine (not shown). The machine base 12 includes a base that rotates around a shaft 16 by one caster 14 and moves between an operating position in which it approaches the wire winding machine and a non-operating position in which it moves away from the wire winding machine. It is equipped with a stand 18. A motor 20 is attached to the lower surface of the machine base 12, and the shaft 16 is driven by this motor 20.

A cylindrical case 24 is fixed to the base 18 via an auxiliary frame 22, and a rotating shaft 28 is attached to this cylindrical case via a bearing 26, and the rotating shaft 28 projects forward from the case 24. The portion is covered by a cylindrical cover 30 screwed onto the case 24. As shown in FIG. 3, a substantially S-shaped blade 32 is screwed to the front end of the rotary shaft 28 that protrudes from the cover 30, and the rear end of the rotary shaft 28 that protrudes from the case 24 rotates around the rotary shaft 28. It is connected to a drive source 34.

In the illustrated embodiment, the rotary drive source 34 includes the rotary shaft 2
8, and a motor 38 mounted on the base 18. The motor 38 is connected to the sprocket 40 and the rear end of the rotating shaft 28, which is in front of the hand handle 36. The transmission is transmitted to the rotating shaft 28 through a chain 46 that extends between the sprocket 44, which is rotatably supported via a bearing 42, and a clutch 48 that is provided between the sprocket 44 and the rotating shaft 28. . Thus, the vane 32 can be rotated by the handwheel 36 or by the motor 38 with the clutch 48 engaged.

Next, to describe the usage state of the present invention, as shown in FIG.
The final end 1b of the fully wound winding is caught by the same catching claw of the catching plate, so these terminals 1a and 1b are tensioned so as to intersect and are pulled out. be done. After capturing the wire ends 1a and 1b in this manner, the motor 20 is driven to move the base 18 to the operating position as shown in FIGS. 1 to 3. In this case, the blade 32 is
If it is kept horizontal as shown in the figure, it will enter between the wire ends 1a and 1b as the base 18 moves to the operating position. In the operating position, the center of the blade 32 is the wire end 1
When lined up at the intersection point 1c of the wire rods 1a and 1b, and in this state turn the manual handle 36 or engage the clutch 48 to drive the motor 38, the blades 32 will rotate and the wire ends 1a and 1b will align at the intersection point 1c. Twisted and tied in the center. Therefore, the winding start end 1a and winding end end 1b of the wire rod coil on the winding bobbin are bundled and fixed.

In the above embodiment, the blade 32 is driven by either the handwheel 36 or the motor 38, but only one of them may be provided.

According to the present invention, as described above, it is possible to easily bind the intersection of the winding start end and the winding end end of the wire rod coil, and since heat is not required to fix them, there is no risk of thermal damage to the wire rod. In addition, the part of the binding machine that has the binding function consists only of one approximately S-shaped blade that engages the intersection of the winding start end and the winding end end of the wire coil, and its rotational drive system. Therefore, the structure is simple and the equipment is inexpensive, and furthermore, it is easy to handle because it is only necessary to move the blade so that both ends of the S-shape fit into the intersection of the wire ends to be bundled and drive the rotational drive source. It is easy to use and has practical benefits.
