Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a manufacturing device for a compensator installed between the bottom of an elevator box and a heavy cone in order to improve the stability of the elevator box. This invention relates to a compensating chain manufacturing device that prevents noise caused by collisions between chain rings during lifting and lowering.

[Conventional technology] Conventionally, as a compensating chain, which aims to prevent noise caused by the collision of chain rings as a box is raised and lowered, a chain is used as a core material, and a fiber rope is set around the core using a rope-making machine, and the chain is woven around the chain. It is known that it is wrapped in a rope shape with fiber cord (Utokai 58
−196354). And this compensation chain is
It is manufactured by using a general rope making machine as is, supplying a chain in place of the core material used in braided ropes, and directly casting fiber rope around the chain.

However, in the case of a compensatory chain manufactured using a general rope making machine as described above, the fiber rope wraps around the chain relatively tightly. This prevents the chain from bending, causing scraping noises when bent, and when the chain bends, the chain rings shift away from each other, and when they return to a straight line, they return to their original positions, producing collision noises. It is the cause of this. In addition, not only is there a limit to how loosely the fiber ropes are tied, but also twine is generally used as the fiber rope for cost reasons, and this tends to shrink due to moisture, so even if the fiber ropes are tied to a certain extent, Even if you hit it loosely, the fiber cords will shrink over time, causing the problem of noise generation.

[Problems to be solved by the invention] The invention easily creates a compensating chain that can reliably prevent the generation of noise by wrapping the chain loosely with the fiber cord without wrapping it tightly enough to impede the chain's flexibility. The problem to be solved is to enable manufacturing.

[Means for Solving the Problems] The measures taken in the present invention to solve the above problems are as follows: In a rope making machine that manufactures knitted ropes by weaving fiber ropes around a core material, The upper end of a guide tube through which the chain passes from the bottom to the top as a core material is located near the braiding position so that the fiber cord is braided on the upper end of the guide tube. To provide a compenchain manufacturing device characterized by being provided with a slide tube that slides up and down to push upward a fiber cord knitted on a guide tube.

[Function] According to the present invention, the fiber cord is once knitted on the guide tube, and then pushed up by the slide tube and around the chain that is moved upward through the guide tube. It will be moved. Therefore,
Even if the fiber rope is braided tightly against the guide tube, if the diameter of the guide tube is adjusted appropriately,
When it is moved onto the chain passing through the guide tube, it will wrap loosely around it. Further, since the braided fiber cord is pushed out as the slide tube slides up and down, even if the fiber cord is braided tightly against the guide tube, it will not be prevented from moving into the chain.

[Example] As shown in FIG. 1, a large number of bobbins 3 on which fiber cords 2 are wound are set up on an upper plate 1, and these bobbins 3 are arranged so that each fiber cord 2 is fed out and raised. The fiber cord 2 is knitted by rotating and moving on the board 1 along a fixed trajectory. Since such a knitting mechanism is well known as a general knitted rope netting machine, a detailed explanation thereof will be omitted here.

A guide tube 4 is erected in the center of the upper panel 1, passing through the upper panel 1. A chain 5 is passed through the guide cylinder 4 from below to above and is gradually moved. In addition, the upper end of the guide tube 4 is located near the point where the fiber rope 2 is braided.
The fiber cord 2 is braided at the upper end of the guide tube 4.

As shown in FIG. 2, a slide tube 6 is loosely inserted into the upper portion of the guide tube 4. The slide tube 6 is pushed up from below by a coil spring 7, and is slid up and down by periodically pulling down a rod 8 using a crank, cam, etc. (not shown). ing. When the slide tube 6 slides upward, the fiber rope 2 knitted on the guide tube 4 is pushed upward and removed from the guide tube 4, causing the guide tube to
It is transferred onto the chain 5 which moves upward through the interior. Furthermore, an F-shaped arm 9 is attached to the circumferential side of the guide tube 4. This arm 9 is for preventing the fiber rope 2 from becoming entangled with the slide tube 6 when the fiber rope 2 is knitted on the guide tube 4.

An introduction guide 10 for smoothly guiding the chain 5 into the guide cylinder 4 is attached to the lower end of the guide cylinder 4, and an alignment guide 11 is located further upstream of the introduction guide 10. . As clearly shown in FIG. 3, the introduction guide 10 is made by bending a U-shaped wire rod into an L-shape, and its upper end is attached to the lower end of the guide tube 4.
The chain 5 is guided so as to be sandwiched between the introduction guides 10 and smoothly guided into the guide cylinder 4. Further, the alignment guide 11 is made by bending a wire rod into a U-shape into an O-shape, and having two corner parts 12 protrude toward the upstream side from both sides of the curved part. The chain 5 is guided so as to be sandwiched between the alignment guides 11, and is aligned from both sides by the corner portions 12 to remove twists and the like. This alignment guide 11
By providing this, it is possible to prevent the chain 5 from being wrapped in the fiber cord 2 in a twisted and irregular state.

[Effect of the invention] According to the invention, the chain 5 can be wrapped loosely with the fiber cord 2, so even if the fiber cord 2 shrinks a little, the chain 5 can be tightly tightened from the surroundings.
There is no way to prevent bending. Therefore, it is possible to prevent noise from being generated due to interference with the flexibility of the chain 5. On the other hand, even if the chain rings of the chain 5 collide with each other to some extent, since the fiber cords 2 are wrapped around them, strong collision will not occur, and a compensating chain with excellent temperature raising effect can be obtained. Furthermore, the device has the advantage that it can be obtained by simple modification of conventional net making machines.
