Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an under-roller type wire winding device, which can be equipped with large-diameter and small-diameter drums.

[Conventional technology and its problems]

An under roller type wire winding device will be explained with reference to FIGS. 1 and 2. In general, two under rollers 1 and 1' are arranged horizontally in a pit 2, , 1', the shaft d of the drum D is supported from above by a bearing 17 provided on a frame 16 on the pit 2, and the drum D is rotated by driving the under rollers 1, 1'. It is used to wind wires such as cables.

However, in this wire winding device, if the drum D is large enough to ride on the under rollers 1 and 1',
A drum D that can wind up the filament but does not rest on the under rollers 1 and 1', that is, a small diameter drum that passes between the under rollers 1 and 1'.
D′ has a problem that makes it unusable.

[Purpose of invention]

In view of the above points, it is an object of the present invention to provide an under roller type wire winding device that can arbitrarily mount large and small drums.

[Means for achieving the purpose of the invention]

In order to achieve the above object, the present invention provides the above-mentioned well-known wire winding device with an elevating roller that is movable up and down by a drive source between the under rollers, and which is mounted on one of the under rollers and the elevating roller. A bearing was installed in the frame to support the shaft of the small-diameter drum.

[Effect]

In the wire winding device constructed in this way, first, when installing a large diameter drum, the lifting roller is lowered below the under roller, and the drum is placed between both under rollers. The shaft is supported by a bearing,
On the other hand, when installing a small-diameter drum that cannot be placed between both under rollers, raise the lifting roller to the same horizontal position as the under roller and place the drum between one of the under rollers and the lifting roller. The shaft is supported by a bearing, and both under rollers or the under roller and the lifting roller are rotated at the same circumferential speed to rotate the drum and wind the filament.

After winding is completed, when the elevating roller is raised, the elevating roller kicks up and pushes out the drum, and the drum is removed from the device.

〔Example〕

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 and 1' are under rollers driven by a drive source (not shown) via shafts 5 and 5' in bearings 4 and 4' installed on the back 3 of the pit 2.
Between the under rollers 1 and 1' there is a sprocket 6,
6' and the endless chain 7, the driving force is transmitted, and the under rollers 1 and 1' rotate at the same circumferential speed.

One end of an arm 8 is rotatably fitted to both ends of the shaft 5 of one under roller 1, and a bearing 9 is provided at the other end, that is, the free end. It is rotatably supported through.

There are pits 2 at both ends of the shaft 11 at the free end of the arm 8.
The bearing 9 is connected to the end of the ram 15 of a hydraulic cylinder 14 which is erected via a pin 13 to a pin seat 12 provided at the bottom of the cylinder.
The lifting roller 10 moves up and down around the shaft 5 to the same horizontal position as the upper and lower positions of the under rollers 1 and 1'.

Reference numeral 15 denotes a large shaft holding means, and a frame 16 is erected on the side upper surface of the pit 2, and a guide column 18 of an open sliding bearing 17 is provided at the center of the frame 16. The opening sliding bearing 17 has a screw shaft 19.
extends through the top of the frame 16, and a handle nut 20 is screwed onto the threaded shaft 19 so as to be rotatable without any movement in the axial direction.
By turning , the open sliding bearing 17 slides up and down the guide column 18 .

Reference numeral 21 denotes a small shaft holding means, in which a bracket 22 is erected on the upper surface of the free end of the arm 8, and a screw shaft 24 with a handle 23 fixed to the end thereof is held up by the bracket 22.
It is threadedly inserted into a nut 25 fixed to the end thereof, and an open bearing 26 is loosely fitted to the lower end of the nut 25.

In this embodiment, the "frame" referred to in the "Utility Model Claims" is comprised of the inner circumferential wall of the pit 2 and the frame 16, and the "bearing" is comprised of the open sliding bearings 17, 26.

This embodiment is constructed as described above, and its operation will be explained next.

First, when mounting a large-diameter drum D, the ram 15 of the hydraulic cylinder 14 is lowered to lower the elevating roller 10 below the under rollers 1 and 1', and between the under rollers 1 and 1' ni drum D
On the other hand, when mounting a small-diameter drum, the elevating roller 10 is raised to the same horizontal position as the under rollers 1 and 1', and the tread plate 2 is
7 on top of the under roller 1', and a small diameter drum is placed on one of the under rollers 1 and the lifting roller 10.
Place D′.

After that, turn the handle 20 or 23 to lower the open sliding bearings 17, 26 and lower the drum D.
Fit it onto the shafts d, d' of D' and support it from above, and in this state both under rollers 1, 1' or under roller 1
And by rotating the lifting roller 10, the drum D,
Rotate D′ and wind up the filament.

When the mounted drums D and D' are fully wound, in order to remove them from the winding device, press the ram 15 of the hydraulic cylinder 14.
By extending the drums D and D' to a large extent and raising the elevating roller 10 greatly, the mounted drums D and D' are kicked out in the direction of the arrow.

In the above embodiment, the lifting roller 10 can be raised and lowered by a screw nut elevator instead of the hydraulic cylinder 14.

Further, gears can be used instead of the endless chain 7 as the driving force transmission means for the under rollers 1, 1'.

Although the driving force is not transmitted to the lifting roller 10 in the above embodiment, it may be connected to the under roller 1 by a chain so that it rotates at the same circumferential speed.

Although the small shaft holding means 21 has a cantilevered structure, it can also have a double-sided structure similar to the large shaft holding means 15.

Further, in the above embodiment, each member is directly installed in the pit 2 with anchor bolts, but it is also possible to assemble a base frame and install it on this.

[Effects of the invention] The present invention is configured as described above, and uses the lifting roller to mount a small diameter drum that could not be mounted on a conventional winding device, so it is possible to use drums of various diameters. This has the effect of increasing the scope of use.
