Description

Description: TECHNICAL FIELD The present invention relates to a bobbin hoisting tool, and particularly to a bobbin hoisting machine capable of hoisting and carrying a plurality of types of bobbins without replacing hooks for hoisting the bobbin. It is about ingredients.

[Prior Art] For enameled wire, for example, round enameled wire, from extra fine enameled wire (wire diameter is about 0.005 mm) to extra thick enameled wire (wire diameter is
There are an extremely large number of types up to 3.5 mm). In the case of enameled wire, the bobbin generally increases in proportion to the diameter, but in recent years, in order to streamline the coil winding work, there has been a growing demand for winding the enameled wire on a large bobbin. The types of bobbins are diversifying accordingly.

As a bobbin for winding the enamel wire, a tapered plastic bobbin 21 as shown in FIG. 4 is often used. Reference numeral 23 is a shaft hole, 24 is an upper collar, 25 is a body, and 26 is a lower collar. The body 25 has a tapered shape in order to smoothly draw out the enamel wire.

In such a bobbin, the winding weight of the enamel wire is, for example,
There are multiple types of bobbins such as 25 kg, 60 kg, and 270 kg, but as the winding weight increases, the shaft hole 23, upper collar 24,
The sizes of the body portion 25 and the lower brim 26 are also increased, and a hanging tool corresponding to them is required.

However, since the work efficiency is poor and the equipment cost is high if a suspender corresponding to each bobbin is prepared, it is desired to realize a suspender capable of transporting these various kinds of bobbins by one suspender. .

In Japanese Utility Model No. 52-119080, in order to be able to carry two types of bobbins with different shaft holes, a large-diameter cylindrical part is arranged above the small-diameter cylindrical part in two concentric cylindrical shapes. A bobbin lifting device has been proposed in which a pair of actuating levers having upper and lower claws protruding outward are provided in a cylindrical portion, and the claws of the actuating lever are projected and retracted from a retractable hole provided in the cylindrical portion to attach and detach the bobbin. .

[Problems to be Solved by the Invention] In such a bobbin suspender, when the claws are projected and retracted, a force for narrowing the outward bending portion provided on the upper portion of the actuating lever inward with human hands (using both hands). Must be applied, which causes a problem in work efficiency. Also, as the bobbin becomes larger, the strength of the actuating lever must be increased, and the weight of the actuating lever increases accordingly, and even greater force is required to act on the outward bending portion when the pawl is retracted. However, there will be a limit to manual operation.

The present invention has been made to solve the above-mentioned problems of the prior art, and efficiently lifts and transports two or more types of bobbins having different sizes, particularly bobbins having a large winding weight, without changing the lifting hooks. It is an object of the present invention to provide a bobbin hanger that can be used.

[Means for Solving the Problem] A bobbin suspending tool of the present invention is provided with a large body formed so as to be inserted into a shaft hole of a large bobbin and a lower body of the large body, and is inserted into the shaft hole of the small bobbin. A small body that is formed so that it can be opened and closed by rotating it around a pivot that is provided in the lower part of the large body and contacts the stopper provided in the lower part of the large body to open horizontally. A pair of large hooks formed so that the upper collar of the large bobbin can be retained and hooked, and provided on the lower part of the small body, which is opened and closed by rotating around a pivot, and is provided on the lower part of the small body. A pair of small hooks formed so that the upper flange of the small bobbin can be hooked while abutting against the stopper and keeping it open horizontally, and the center of the large body and the small body. It consists of a large hook and a rod that controls the opening and closing of the small hook through a link, and the load when the large bobbin is suspended is the stopper provided at the bottom of the large body. The load when the small bobbin is suspended to the large body via the above is added to the small body and the large body via a stopper provided at the bottom of the small body, and is configured not to be added to the rod. It is characterized by.

[Operation] By providing a large hook for lifting a large bobbin and a small hook for lifting a small bobbin in two stages, it is possible to lift and transport two types of bobbins of different sizes without exchanging the hooks.

In addition, both the large hook and the small hook are opened and closed by rotating around the pivot, and they are in contact with the stopper to maintain the horizontally opened state. In addition to the large body and the small body, the rod and link that control the opening and closing of the hook will not be directly added, and the handling and operability of these systems can be improved, and the opening and closing of the hook can be performed very easily with one touch. .

[Embodiment of the Invention] An embodiment of the present invention will be described with reference to FIGS. 1 and 2. 1 is a partial cross-sectional side view of an embodiment of the present invention, and FIG. 2 is a cross-sectional explanatory view taken along the line XX 'in FIG.

Reference numeral 1 denotes a large body, the outer diameter of which is slightly smaller than the diameter of the shaft hole of the large bobbin so that it can be inserted into the shaft hole of the large bobbin.

2 is a small body, which is connected to the lower end of the large body 1 and has an outer diameter slightly smaller than the shaft hole diameter of the small bobbin, so that it can be inserted into the shaft hole of the small bobbin. There is.

Reference numeral 9 denotes a large hook. The large hook 9 is rotatably attached to a lower portion of the large body 1 about a pivot 13 as a fulcrum and abutted against a lower stopper 7 to maintain a horizontally opened state. It is designed so that the upper collar of a large bobbin can be hooked and lifted.

Reference numeral 10 denotes a small hook. The small hook 10 is rotatably attached to the lower portion of the small body 2 about a pivot 14 as a fulcrum and abuts against a lower stopper 8 to maintain a horizontally opened state. It is designed to hang on the upper collar of a small bobbin.

3 is a rod, which is a large body 1 and a small body 2
Is provided so as to communicate with the central part of the. A lever 4 is attached to the upper portion of the rod 3 and projects to the outside of the large body 1. When the lever 4 and the handle 5 attached to the large body 1 are manually grasped and the lever 4 is pulled up, the rod 3 moves upward, and when the lever 4 is released, the rod 3 moves downward.

The rod 3 is a link 11 with a large hook 9 and a support.
The support 19 is fitted and fixed to the rod 3, and the support 19 and the link 11 are pin 16
Since the link 11 and the large hook 9 are rotatably connected by the pin 15, the link 11 and the large hook 9 are rotatably connected by the pin 15. Therefore, when the rod 3 is pulled up, the large hook 9 rotates about the pivot 13 in the direction of the arrow. Close. Thus, with the large hook 9 closed, the large body 1 is inserted into or removed from the shaft hole of the large bobbin. On the contrary, when the lever 4 is released and the rod 3 moves downward, the large hook 9 rotates and opens in the opposite direction, and the stopper 7 stops at a position horizontal to the installation surface. With the large hook 9 open like this, the large bobbin
The upper flange 24 of 21 can be hooked and lifted.

Similarly, the small hook 10 is rotatably connected to the rod 3 via the links 12 by the pins 17 and 18, and when the rod 3 is pulled up, the small hook 10 moves in the direction of the arrow with the pivot 14 as the fulcrum. Turn to close. Also,
Release the lever 4 and move the rod 3 downwards.
10 rotates in the opposite direction to open, and stops at a position horizontal to the installation surface by the stopper 8.

In this way, the rod 3 can be moved up and down by a one-touch operation of grasping and releasing the lever 4.
Thereby, the large hook 9 and the small hook 10 can be easily opened and closed. In particular, since the load of the bobbin is applied to the large body 1 and the small body 2 and not directly to the rod 3, the links 11 and 12 that control the opening and closing of the large hook 9 and the small hook 10, the structure of these opening and closing mechanisms is made lightweight. The simplification and easy opening / closing operation of the large hook 9 and the small hook 10 enable efficient lifting and carrying of the bobbin.

In FIG. 1, 6 is a bush for supporting the rod 3.

Next, the operation of hoisting and carrying the bobbin will be described with reference to FIG.

Operate the bobbin suspender 28 to move it above the small bobbin, grasp the lever 4 and the handle 5, lift the lever 4 and close the large hook 9 and the small hook 10, and move the bobbin suspender 28 to the shaft of the small bobbin. When descending along hole 23,
The small body 2 is inserted into the shaft hole 23. Then, when the lever 4 is released, the small hook 10 is opened by its own weight and comes into contact with the stopper 8 to be opened horizontally. In this state, when the bobbin suspending tool 28 is raised, the small hook 10 is lifted by the upper collar of the small bobbin. Can be hooked to 24 and lifted.

A large bobbin can be lifted in the same manner. That is, the bobbin suspending tool 28 is operated to move the bobbin up and down, grasp the lever 4 and the handle 5, and move the lever 4
With the large hook 9 and the small hook 10 closed, the bobbin suspending tool 28 is lowered along the shaft hole 23 of the large bobbin until the large body 1 is inserted into the shaft hole 23. Then, when the lever 4 is released, the large hook 9 and the small hook 10 open due to their own weight, and they come into contact with the stoppers 7 and 8 to open horizontally, and when the bobbin suspending tool 28 is raised in this state, the large hook 9 Is a large bobbin top guard 24
Can be hooked and lifted.

In the above embodiment, the large hook 9 and the small hook are used.
Although 10 is explained as opening by its own weight, a spring is attached to the upper part of the rod 3 so that the rod 3 can be pushed downward, and the downward movement of the rod 3 is facilitated, so that the large hook 9 and the small hook can be provided.
It is also possible to make 10 easy to open.

[Effects of the Invention] As described above, according to the present invention, by providing a large hook for lifting a large bobbin and a small hook for lifting a small bobbin in two stages, two types of bobbins of different sizes can be used without replacing the hooks. It is possible to lift and transport.

In addition, both the large hook and the small hook are opened and closed by rotating around the pivot, and they are in contact with the stopper to maintain the horizontally opened state. In addition to the large body and small body, which do not directly add to the rods and links that control the opening and closing of the hooks, the operability of these systems can be improved, and the opening and closing of the hooks can be performed very easily with one touch. , The bobbin can be lifted and transported efficiently.
