Description

[Detailed description of the invention] The present invention is a wire winding machine in which the winding start end of a wire rod to be wound on a winding drum is wound around an outer winding drum outside the winding drum. This relates to a fixing device that is fixed to the collar of a take-up drum.

Generally, when a wire such as an electric cable is wound around a winding drum, the starting end of the wire is led out of the winding drum for a considerable length so that various electrical or mechanical properties can be inspected. required. For this reason, when winding a wire rod in a wire rod winding machine, an outer winding drum is installed outside the winding drum, and the winding start end of the wire rod is wound onto this outer winding drum before the main winding. In the conventional technology, when removing the winding drum from the wire winding machine after the main winding of the wire rod, the worker tied the outer winding part with string, etc., and manually nailed this string to the collar of the winding drum. . However, this method requires hands to be inserted between the machines, which is not only unsafe, but also inefficient, and the product is easily damaged.

An object of the present invention is to provide an outer-wound part fixing device for a wire winding machine that can mechanically and efficiently fix the outer-wound part wound around the outer-wound drum.

Embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show a wire winding machine 12 equipped with an outer winding part fixing device 10 according to the present invention. Reference numeral 12 includes a pair of support shafts 16 and 16' rotatably attached to the machine base 14, and the winding drum 18 is supported by these support shafts 16 and 16'. One of the support shafts 16 has a bulge pin 16a on the flange portion that abuts against the flange of the winding drum 18. 18 in the rotational direction. This support shaft 1
A rotary drive source (not shown) is connected to 6, and the winding drum 18 is configured to wind the wire onto the winding drum 18.
Rotate. The wire winding machine 12 also has a support shaft 1
An outer drum 20 is rotatably supported at 6', and the outer drum 20 is rotationally driven by an auxiliary rotation drive source (not shown). On the outside of the outer drum 20, there is a crimping plate 22 that presses the winding start end of the wire led out to the outside of the outer drum 20 through the side ports (not shown) of the drums 18, 20 to the collar of the outer drum 20.
A crimping means 24 including a crimping means 24 is provided. In this state, the winding start end 1a of the wire rod 1 is wound around the outer winding drum 20 in a predetermined turn as the outer winding portion 2 by driving the auxiliary rotary drive source while applying a brake to the rotary drive source. (See Figure and Figure 4).

The outer winding part fixing device 10 of the present invention, as shown in FIG.
B and 10C, but since these device parts have the same structure, only one of them will be explained. 3 and 4 show one part of the device, which straddles the outer part 2 wound around the outer drum 20 and attaches the outer part 2 to the collar 18a of the take-up drum 18. Nail storage means 28 for storing a plurality of inverted U-shaped nails 26 to be driven in a fixed manner and biasing each nail 26A so as to be exposed at the nail driving position A; Remove one nail 26A from other nails and crimp plate 2
2 and a nail conveying means 30 for conveying one nail 26A so as to straddle the outer portion 2 through the notches 22a and 20b of the collar 20a of the outer drum 20; and a nail driving means 32 for driving one nail 26A into the collar 18a of the winding drum 18. Nail storage means 28
is provided with a spring 33 to expose one nail 26A to the nail driving position A, and this nail 26A is prevented from exceeding the nail driving position A by a stopper (not shown). The nail transport means 30 includes an inverted U-shaped transport tool 34 shaped to store one nail, and a transport tool 34 that stores one nail 26A from the position shown in FIGS. is notch 20
b and a fluid cylinder 36 that is driven through 22a to a position where it straddles the outer wound portion 2. The nail driving means 32 transfers one nail 26A, which has been moved so as to straddle the outer winding portion 2, to the carrier 34.
It consists of a hammer 38 that escapes from the winding drum 18 and hits the collar 18a of the winding drum 18, and a fluid cylinder 40 that drives this hammer.

This outer winding part fixing device 10 is a winding start end 1 of a wire rod.
After winding the wire rod 1 outward, and then winding the wire rod 1 into the winding drum 18, when the notches 20b and 22a of the outer winding drum 20 and the crimping plate 22 are aligned with the nail driving position A, the nail conveying means 30 is driven. One nail 26A is conveyed so as to straddle the outer part 2, and then the nail driving means 32
is driven to drive this one nail 26A into the collar 18a of the winding drum 18 while straddling the outer winding portion 2, thereby fixing the outer winding portion 2 to the collar 18a of the winding drum 18. In the embodiment of the present invention, since there are three device parts, one nail 26A is driven into each device part, and the outer winding part 2 is moved to the winding drum 18 in one operation.
can be fixed to.

According to the present invention, as described above, the outer portion of the winding drum that has been led out to the outside of the winding drum for a considerable length is automatically nailed, thereby safely and efficiently without damaging the product. There is a practical benefit in that the outer part can be fixed.
