Abstract

PURPOSE:To aim at the contraction and uniformization of a lashing wire pitch, by installing a bundle of messenger wire and cable as well as a lashing wire guide apparatus in the arm tip being projected in a delivery direction of the lashing wire. CONSTITUTION:A messenger wire 10 and a cable 11 both are passed through an inner cylinder 1 and further through a bundling pipe at the arm tip part. Next, one end of a lashing wire 7 being rolled round on a bobbin 3 is hooked to a delivery roller and also to a delivery guide roller 19 and locked to the messenger wire 10. And, when a machine is pulled forward, the lashing wire 7 is played out of the roller 19 and coiled in spiral form on the periphery of the messenger wire 10 and the cable 11. Since the lashing wire is played out of a spot in close vicinity to a bundling device and a cable and so on, irrespective of size in each cable diameter, a winding pitch can be made smaller and simultaneously uniformization can be brought to fruition.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a centering mechanism for a lashing machine.

As shown in FIGS. 1 and 2, a conventional lashing machine has an outer cylinder 2 rotatably provided on the outer periphery of an inner cylinder 1, and a bobbin 3 rotatably mounted on a shaft protruding from the outer surface of the outer cylinder 2. Also, a bevel gear 4 is provided on the rear flange 1aG of the inner cylinder 1.
A friction roller 6 having a pinion gear 5 that meshes with the outer cylinder 2 is rotatably provided on the outer surface of the outer cylinder 2. Then, one end of the lashing wire 7 wound around the bobbin 3 is let out and wound around the friction roller 6, and is further attached to the tip of a support rod 8 that protrudes rearward from the friction roller 6 (to the right in FIGS. 1 and 2). ◇Front part 7 of inner cylinder 1
The machine moves forward by pulling the train arm protruding from the lunge 1b 12 minutes forward (to the left in Figures 1 and 2), which causes the lashing wire 7 to be paid out from the bobbin 3, causing the friction roller 6 to rotate. As a result, the pinion gear 5 integrated therewith rotates along the outer periphery of the bevel gear 4. This causes the outer cylinder 2 to rotate around the outer periphery of the inner cylinder 1, so that the lashing wire 7 that is fed out spirally wraps around the outer periphery of the messenger wire 10 and the cable 11, and bundles them together. However, a centering mechanism 13 is provided on the rear surface of the rear flange 1a of the inner cylinder 1 so that the lashing wire 10 and the cable 11 can come out from the center of the machine. 13 Once hooked onto the feeding roller 9 of the support rod 8 that protrudes to the side of the outer periphery, the wire is directed from that point toward the Messenger wire 10 and the cable 11. The lashing wire 7 thus wraps around the mesh senger wire 10 and the cable 11 at a location remote from the machine.゛On the other hand, when the mama machine is towed, the machine shakes, and the mesh wire 10 and cable 11 that come out of the machine may also shake vertically and horizontally.
Coupled with the fact that the lashing wire 7 is wound around the metsenger wire 10 and the cable 11 at a position away from the cable 11, the pitch of the winding of the lashing wire 7 becomes uneven. Furthermore, if the cable 11 of this machine has a small diameter, it can only be wound at a large pitch, and the pitch will be uneven. If the cable diameter is small, a smaller machine may be used, but it is uneconomical to manufacture and prepare a machine with a different length to match the cable diameter.

Further, although the above conventional example is a movable lashing method, there is also a fixed lashing method different from this. That is, the shaft is passed through the traction arm 12 of the machine, so that the machine can be rotated freely and supported on a suitable object such as a utility pole, and one end of the lashing wire 7 is fixed to one end of the metsenger wire 10 and cable 11 that have passed through the machine. These messenger wires 10 and cables 11 are then pulled out. In this case, the Metsenger wire 10 and cable 11 that come out of the machine sway vertically and horizontally due to the extension of the Metsenger wire 10 and cable 11.
The lashing wire 7 is connected at a location away from the centering mechanism 13.
If the lashing wire IO and cable 11 are wrapped around each other, there is a risk that the mesh senger wire 10 and cable 11 may be placed at a position offset from the center of the two feed rollers 9, and the winding of the lashing wire 7 may be becomes non-uniform.

This is remarkable in the case of mobile devices.

This invention was made in view of these points, and instead of the conventional centering mechanism, an arm is made to protrude outward from the outer cylinder of the machine, and a convergence device for the mesh wire and cable is provided at the outer end of this arm. Along with this convergence device,
A guide roller for feeding out the lashing wire is installed close to the metsenger wire and cable.
This provides a centering mechanism for a lashing machine that can reduce the winding pitch of the lashing wire and make the pitch uniform regardless of the diameter of the cable.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 6. Swollen portions 14 a at both ends of the approximately U-shaped naam 14
A bolt hole 15 is bored in the blade, and a box-shaped frame 16 is provided at the center of the sword tip 14b, and a convergence tube 17t is rotatably provided, passing through the entire front and rear sides of the frame 16.

Furthermore, bearings 18 are provided protrudingly on both sides of the frame 16, and a guide roller 19 for feeding out the lashing wire 9 is rotatably provided on each of these bearings 18. Then, the bolt hole 15 of the bulging part 14a of the arm 14 is fitted into the bolt shaft of the friction roller 6 which protrudes from the outer surface of the outer cylinder 2 of the lashing machine, and the wing nut 21 is screwed onto the bolt hole 15 of the arm 14. is fixed to the outer cylinder 2.

To perform lashing using this rack:
It passes through the converging tube 17 of b. Then, one end of the lashing wire 7 wound around the bobbin 3 is paid out, and this is wound around the friction roller 6 and applied to the feeding roller 9.
The tip end 14b of the arm 14 is fixed to the mesh wire 10 by passing through the guide roller 19 for feeding out the lashing wire. When this lashing machine is pulled forward (to the left in FIGS. 3 and 6), the lashing wire 7 is fed out from the lashing wire feeding guide roller 19, and is attached to the outer periphery of the mesh wire 10 and the cable 11 as shown in FIG. The second part is wound in a spiral as shown in the figure. This also applies to fixed types.

The metsenger wire 10 and cable 11 that have passed through the inner cylinder 1 are bundled together through the convergence tube 17, while the lashing wire 7 is connected to the lashing wire at a location close to the convergence tube 17, the metsenger wire 10, and the cable 11. Since it will be fed out from the feeding guide roller 19, it will be wrapped around the messenger wire 10 and cable 11 very close to the convergence tube 17. Therefore, even if the metsenger wire 10 and the cable 11 move vertically and horizontally at the rear of the machine (or at the front in the case of a fixed type), the winding pitch of the lashing wire 7 is reliably uniform.

Furthermore, even in the case of a small diameter cable 11, by attaching the arm 14 having the converging tube 17 and the guide roller 19 for feeding out the lashing wire of the present invention to a large diameter machine, the cable 11 can be used with a small pitch and uniformly. can be wrapped around. Therefore, there is no need to prepare lashing machines with different diameters, which is economical.

Further, in the above embodiment, the frame 1 of the tip portion 14b of the arm 14
Since the converging tube 17 is rotatably provided in the cable 6, the cable 11 and the mesh wire 10 are not twisted due to friction. In addition, in the above embodiment, the converging tube 17 and the feeding guide roller 19 are positioned at a certain distance behind the machine via the arm 14 to resist the traction of the machine (in the case of a fixed type, the mesh tensioner wire 10
This is to avoid increasing the pull-out resistance.

In addition, the focusing tube 17 in the above embodiment is a focusing device (centering mechanism).
This is one embodiment, and instead of this, a four-sided roller, a seven-figure roller, etc. may be used.

Furthermore, it goes without saying that the focusing device of the present invention may be attached to a conventional centering mechanism.

As described above, in this invention, the end of the arm protruding in the direction in which the lashing wire is fed out converges the metsenger wire and cable, and the lashing wire is fed out from a location near the convergence device and the cable. The lashing wire wraps around the Metsenger wire and cable at a location close to the device.
Therefore, winding has the effect of making the pitch uniform.
