Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an apparatus for supporting a plurality of magnetic separators in an adjustable position.

[Prior art]

This type of magnetic separator is used to apply a magnetic field to the end surfaces of stacked sheets of sheet material, such as steel plates, to separate them. Therefore, the magnetic separator must be placed as close as possible to the end surface of the sheet material. Therefore, when the dimensions of the sheet material change, the mounting position of the magnetic separator is adjusted each time to an appropriate position using fixing means such as a tightening screw.

[Problems with conventional technology]

However, since such adjustment work is complicated, a lot of time and effort are spent on changing the setup.

In addition, for example, in a device such as that disclosed in Japanese Utility Model Application Publication No. 58-18641, the amount of movement of the pair of left and right magnetic separators is independent and not related to each other, making it difficult to align the pair of magnetic separators with respect to the sheet material. be.

[Purpose of invention]

Therefore, an object of the present invention is to enable the position of the magnetic separator to be easily adjusted when the dimensions of the sheet material change, thereby reducing the labor and time required for changeover.

[Means of solution and action of the invention]

Therefore, in the present invention, a pair of magnetic separators are slidably supported on a substrate by a slider, and a means for adjusting the position of these magnetic separators is composed of a reverse feed screw shaft, a feed nut, and a pair of links. There is.

As the feed screw shaft rotates, the feed nut and the pair of links, which are in a reverse screw relationship, convert the rotational motion of the screw shaft into linear motion and transmit it to the slider. At this time, since the pair of magnetic separators move by the same amount relative to the sheet material, changeover is easy, and there is no need to adjust the center alignment between the sheet material and the pair of magnetic separators.

〔Example〕

1, 2 and 3 show a magnetic separator support device 1 of the present invention.

A magnetic separator support device 1 is provided on a substrate 2. This substrate 2 has a square shape, for example, and supports a slider 4 slidably toward the center by a pair of guide members 3 at positions near each opposing side of its upper surface. Each slider 4 supports a magnetic separator 5 at its central portion in a manner that it can move toward the center and move toward and away from the magnetic separator 5.

On the other hand, the substrate 2 rotatably supports four feed screw shafts 7 along each side in a parallel opposed state by bearings 6 provided at each corner.
These feed screw shafts 7 are connected to feed nuts 9a, 9b by feed screws 8a, 8b in opposite directions.
are screwed together. Also, these feed nuts 9a,
9b is a pair of links 1 by pins 10 respectively.
It is connected to one end of 1. The pair of links 11 are connected to the back side of the slider 4 by a connecting pin 12 at the other end.

Adjacent ones of the four feed screw shafts 7 are connected to each other by bevel gears 13 and 14 at the ends so that rotation can be transmitted. One of the feed screw shafts 7 is provided with a handle 15 for operation. Note that a locking gear 17 is attached to one of the feed screw shafts 7, and a set screw 18 on the board 2 side allows all the feed screw shafts to be fixed at a predetermined rotational position in a non-rotating state. It's getting old.

Next, the operation of the magnetic separator support device 1 will be explained together with the function of the device.

When the worker rotates the handle 15 and moves the feed nuts 9a and 9b of the same feed shaft 7 in the direction toward each other, the pair of links 11 deform the isosceles triangle and move the slider 4 toward the center. move it. At this time, all the magnetic separators 5 move toward the center with the same amount of displacement and approach, for example, the outer peripheral surface of the disc-shaped sheet material 16 while maintaining the same distance.

On the other hand, if the worker rotates the handle 15 in the opposite direction to the above case, the feed nuts 9a and 9b will
The sliders 4 move away from each other, increasing the intersecting angle of the pair of links 11, and retreating the slider 4 together with the magnetic separator 5. In this way,
All the magnetic separators 5 advance or retreat toward the center by the same amount of movement from the four positions to prepare for changes in the external dimensions of the sheet material 16.

After the adjustment, the shaft 7 is set in a non-rotating state by the set screw 18, so that the magnetic separator 5 is reliably fixed in the adjusted position.

[Other Examples]

In the above embodiment, four magnetic separators 5 are provided as an example, but it is sufficient to provide at least one pair of magnetic separators 5, and therefore the other two may be omitted. .

Further, although the above embodiment includes the handle 15 as a rotating means for the feed shaft 7, this driving means can also be constructed by a motor that can control the amount of rotation and can rotate in either forward or reverse directions. .

[Effect of idea]

In the present invention, by rotating the feed screw shaft, at least one pair of magnetic separators move toward the center by the same amount, and move forward or backward, and can be set at the most appropriate position relative to the sheet material. There is no need for centering work, and this operation can be performed easily and with light operating force by rotating the feed screw shaft, so that setup changes can be made easily and quickly when the dimensions of the sheet material change.
