Abstract

An object of the present invention is to provide a gap-free foreign matter removing apparatus that completely removes magnetic foreign matter in a medium supplied by dropping.
A large number of teardrop-shaped or drop-shaped bar magnets disposed in a chamber 2 of the apparatus are inclined and disposed without gaps when viewed from the falling direction of a medium 4. Thereby, the magnetic foreign material 3 is completely removed. The bar magnets are arranged to be inclined with respect to the falling direction of the medium, and the bar magnets are arranged so that the inclination directions are the same or opposite to each other.

Description

  The present invention relates to a foreign matter removing device that removes magnetic foreign matter contained in a medium to be supplied by dropping, and in particular, a plurality of upper and lower bar magnets arranged in the device have gaps when viewed from the falling direction of the medium. The present invention relates to a foreign matter removing apparatus without gaps that is arranged without any gaps.

In many cases, the fall-supplied medium contains magnetic foreign matter, and in this state, a foreign matter removing apparatus has been conventionally used to remove the medium being sent to the next process side. This foreign matter removing apparatus is configured by arranging a large number of the internal bar magnets. For example, the apparatus shown in “Patent Document 1” can be cited as an example.
JP 2003-211022 (FIG. 1)

  The “magnetic foreign matter removing method and apparatus” of “Japanese Patent Application Laid-Open No. 2003-211022” of “Patent Document 1” has a large number of bar magnets (8) arranged in a chamber (1). These bar magnets (8) are arranged in the vertical direction (same direction) and the horizontal direction with respect to the medium drop supply direction, and these bar magnets (8) have a gap when viewed from the medium drop direction. Are arranged in a state.

  In the case of the “magnetic foreign matter removing device” having the above-described structure, a medium to be dropped and fed is sent through the gap between the bar magnets (8), and some of them are not magnetically attached to the bar magnet. As a result, there is a problem that the magnetic foreign matter cannot be completely removed.

  The present invention has been devised to solve the above problems, and an object of the present invention is to provide a gap-free foreign matter removing device in which a fallen and supplied medium always comes into contact with a bar magnet to completely remove magnetic foreign matter. And

  In order to achieve the above object, the present invention provides a foreign matter removing device for magnetically removing magnetic foreign matter in a fall-supplied medium, wherein the device is a cylinder that opens up and down. The bar magnet includes a bar magnet disposed on the upper side and a bar magnet disposed on the lower side of the bar magnet as viewed from the falling direction of the medium. It is characterized by being arranged without gaps.

  The invention of claim 2 is characterized in that the bar magnet is of a teardrop type or a drop type, and the bar magnet is arranged to be inclined with respect to the falling direction of the medium.

  Further, the invention of claim 3 is characterized in that the bar magnets are arranged in the same direction or in opposite directions.

  According to the non-gap foreign matter removing apparatus of claim 1 of the present invention, since the bar magnets arranged in the apparatus are arranged without gaps, all of the fall-supplied medium contacts the bar magnet and is included in the medium. The magnetic foreign matter is completely removed by magnetic adhesion.

  Further, according to the gapless foreign matter removing apparatus of claim 2 of the present invention, since the bar magnet is made of a teardrop type or a drop type and is disposed at an inclination, the magnetic foreign matter is sent without being deposited on the bar magnet. As a result, the magnetic foreign matter is completely removed.

  Further, according to the gap-free foreign matter removing device of claim 3 of the present invention, the inclination direction of the tear-type or drop-type bar magnet is arranged in the reverse direction, and the same even if the inclination directions are different. Magnetic foreign matter is removed. In addition, the selection of the inclination direction as the same or the reverse direction is performed corresponding to the entire structure of the apparatus, and the degree of freedom of arrangement of the apparatus structure is improved.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a gap-free foreign matter removing apparatus according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic longitudinal sectional view showing the overall structure of the foreign substance removing apparatus without gaps.
As shown in the figure, the gap-free foreign matter removing apparatus 100 includes a chamber 2 in which openings 5 and 6 are formed on the upper and lower sides, and a bar magnet 1 disposed in the chamber 2.

  In the present embodiment, a teardrop-type or drop-type bar magnet 1 is employed, but the bar magnet 1 may have another shape as long as it is arranged without a gap. However, this tear-type or drop-type bar magnet 1 is desirable for removing magnetic adhesion without depositing magnetic foreign matter.

As shown in FIG. 1, the bar magnet 1 is disposed to be inclined with respect to the falling direction of the medium 4 (the X direction in FIG. 2A).
FIG. 2A clearly shows the arrangement structure of the bar magnet 1 in FIG. 1, and the bar magnet 1 is the base of the bar magnet 1 at the bottom of the line along the X direction from the top 1a of the bar magnet 1 on the upper side. It arrange | positions so that the part 1b may contact | connect.
Accordingly, when FIG. 2A is viewed from above along the falling direction (X direction) of the medium 4 (see arrow A), the bar magnets 1, 1, 1 are arranged without a gap as shown in FIG. 2B. Has been.
With the above structure, all of the medium 4 dropped and supplied from the upper opening 5 comes into contact with the bar magnet 1, and all the magnetic foreign matter 3 contained in the medium 4 is magnetically attached to the bar magnet 1 and removed. Further, as described above, the bar magnet 1 is of a teardrop type or a drop type, and the medium 4 or the magnetic foreign matter 3 is not deposited on the top portion 1a of the bar magnet 1. Thus, the medium 4 from which the magnetic foreign material 3 has been removed is sent from the lower opening 6 to the next process side.

  In the first embodiment, the tear-type or drop-shaped bar magnet 1 is arranged to be inclined in the same direction. However, in the “Example 2”, the bar magnet 1 is arranged in different inclination directions as shown in FIG. The In other words, the X-direction line from the top portion 1a of the upper bar magnet 1 is arranged in a state where the top portion 1a of the lower bar magnet is in contact, and the lower bar magnet 1 is also in contact with the top portion 1a. It is arranged with. With the above structure, when the bar magnets 1, 1, 1 are viewed from the direction of the arrow A in FIG. 2A, the bar magnets 1, 1, 1 are arranged without a gap in substantially the same manner as in FIG. As described above, the magnetic adhesion removal of the magnetic foreign matter 3 almost the same as that described in the first embodiment can be performed.

  In the above description, the inclination is the same for all the bar magnets 1, but the inclination may not be the same. Further, the structure of the apparatus and the structure of the bar magnet are not limited to the contents described above. Of course, those of the same technical category are adopted.

  The present invention can be applied to all types of foreign matter removing apparatuses and has a wide range of uses.
