Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a wire bundler for winding wire, and particularly to improvements in the winding frame.

(Prior art) A wire rod bundle counting/binding wrapping machine usually includes a measuring unit that continuously measures the wire to be wound, a bundle counting machine that winds the measured wire onto a winding frame, and a winding unit. It consists of a binding section that bundles the bundled wire rods with string, a measuring section that weighs the bundled wire rods, and a paper wrapping machine that wraps the wire rods after weighing with wrapping paper.

As shown in FIGS. 11 and 12, the bundle counting machine includes a first flange disk 3 fixed to one end of a drive shaft 2 of the bundle counting machine 1, and a winding drum 4. This winding drum 4 has a diameter smaller than that of the flange disk 3 and is equally divided in the circumferential direction on the circumference of a concentric circle. The bar 5 is fixed to a rotating shaft 6 aligned with the drive shaft 2 below the winding drum 4, facing the collar disk 3, and facing the winding drum 4.
a second flange disk 7 whose free ends are arranged so as to be able to approach and separate; and a flange disk 7 which is fitted between these two flange disks 3 and 7 and movably in the axial direction on the winding drum 4. a third collar disk 8 having the same diameter as 7;
A plurality of spacers 9, for example, four spacers 9, are arranged between the flange disks 3 and 8 at equal intervals on the same circumference, and each of these spacers 9 is arranged between the flange disks 3 and 8. A winding frame 12 is formed by the second flange disk 7, the third flange disk 8, and the winding drum 4, and the spacer 9 connects the flange disk 7. The interval between and 8, that is, the bundle width of the wire rod to be wound is set.

After winding the wire around the winding frame 12, when the drive shaft 2 is moved upward as shown by the arrow in FIG. 15 and the disk 17 provided on the drive shaft 2, and each spring 18 stretched between the other ends 5b of the adjacent barbs 5. Due to the spring contraction force of the spring 19, each roller 20 provided inside the other end 5b of each barb 5 falls into the small diameter portion 2a provided at the tip of the drive shaft 2, and the free end of the winding drum 4 is reduced in diameter. As a result, the winding drum 4 can be easily removed from the wound wire bundle 13 as shown in FIG. As a result, a wire bundle 13 having a bundle width W as shown in FIG. 13 is obtained.

When changing the bundle width, for example, when changing from the bundle width W in FIG. 11 to the bundle width W (>W) in FIG. 14, remove each threaded rod 1o, pull out each spacer 9, and then The flange disk 8 is brought into close contact with the first flange disk 3, and each spacer 9 is attached to the upper surface of the first flange disk 3 in that state using a threaded rod 10 and a nut 11.
The tsuba disk 8 is tightly fixed to the tsuba disk 3 by
The distance between the second flange disk 7, that is, the bundle width is set to W.

In this way, the spacer 9 switches the winding width (bundle width) of the winding frame 12 into two stages. This switching work (setup change work) is performed by one worker, and the required time is approximately 20 minutes.

(Problem to be solved by the invention) The switching time of the winding width did not pose much of a problem in the era of same-lot, mass production because the linear speed of bundle take-up was relatively slow. As linear speeds increase, needs become more diversified, and as high-mix, small-loft production becomes established, shortening the so-called upper nodal amplifier time has become a focus, and speeding up of this switching work has also been required. .

Furthermore, the problem with the two-stage bundle width switching operation is that when switching to either side of the bundle width W<w>, when the napht 11 is removed in order to move the spacer 9, the third collar disk 8 by hand, and the tsuba disc 8 remains until the set is completely completed.
The point is that it can be adjusted by moving it up and down. This work may seem simple at first glance, but it is a difficult work that requires a lot of strength and requires only one worker. This is because even if the intermediate third flange disk 8 is tilted even slightly, the clearance between its inner diameter and the outer periphery of the winding drum 4 is small, causing it to twist and not move. This is because if the object falls suddenly, it must be moved up and down while maintaining a horizontal state, which requires force. Moreover, since there are movable parts such as the east moving device near the reel, there is not enough space to work, forcing workers to work in uncomfortable positions, which can cause back pain.
Alternatively, the intermediate flange disk 8 may not be able to support it enough and fingers may get caught, making it difficult to shorten the time required for the switching operation.
Further, there is a problem that this time also differs depending on the worker.

The present invention has been made in order to solve the above-mentioned problems, and provides a wire rod bundling machine that facilitates the wire width switching operation, shortens the switching operation time, and improves the safety of the operation. The purpose is to

The flange disk 8 moves downward and separates from the first flange disk 3. The transition ends at the position where each cam follower 40 fits into the lower locking portion 31C of each cam 131b.

Rotate the cylindrical cam member 31 to this final position (rotation angle θ)
After that, pull each knob 50°50 of the stopper 45.45 slightly outward to remove each pin 48 from ■a46d (only one is shown in Fig. 7), and rotate it 90° to remove the pin 48 from the slit 46C.
When the knobs 50.50 are released, each stopper bin 47.47 protrudes by spring force, and its tips 47b, 4
7b fits into the recesses 31f' and 31f' of the cylindrical cam member 31.

Thereby, the cylindrical cam member 31 is locked to the first collar disk 3.

In this state, each cam follower 40 is connected to each cam groove 31.
The third flange disk 8 is locked at the second bundle width switching position of b, and the third flange disk 8 descends to the lowest position as shown in FIG. The distance from the disk 7 is the minimum bundle width w (
<W), these first bundle width W and second bundle width w(
<W) is the difference ΔW between the upper and lower locking portions 31 of the cam groove 31b.
d, determined by the spacing between 31c. After the bundle width switching is completed, the handle 55.55 is removed from the cylindrical cam member 31 and attached to the holder 56.

When switching the bundle width from the second switching position to the first switching position, the cylindrical cam member 31 is rotated clockwise as shown by arrow C in FIG. 2, contrary to the above description. In this way,
Change the bundle width to 2 stages.
