てのみ考慮されてきた。The magnet type attracting device having the above-mentioned various structures is designed so as to obtain a desired attracting force according to the required application. The force has been considered only for the attraction force in the direction perpendicular to the attraction magnetic pole surface (for example, the attraction force indicated by F 1 in FIG. 8).

点から改良された磁石式吸着装置の提案はなかった。Increasing the attraction force in the direction perpendicular to the attraction magnetic pole surface is effective in applications such as hoisting and transporting an object to be attracted such as a steel plate or a machined work, but the attraction arrangement on the magnetic wall surface In applications such as a hanger used as a fixing tool or a fixing jig used on a magnetic surface plate, the attraction force in the parallel direction rather than the attraction force in the direction perpendicular to the attraction magnetic pole surface (for example, in FIG. 8). It is required to increase the adsorption force indicated by F 2 . However, up to now, there has been no proposal of an improved magnet type adsorption device from such a viewpoint.

いの煩雑さを招くこととなる。The attraction force in the direction parallel to the attraction magnetic pole surface is based on the attraction force in the direction perpendicular to the attraction magnetic pole surface of the yoke generated when the device and the object to be attracted attract each other. Since it is determined by the frictional force between the magnet and the magnet, if the size of the permanent magnet or electromagnet serving as the magnetic field generation source is increased simply for the purpose of increasing the vertical attraction force, the size of the apparatus itself becomes large and the handling becomes complicated.

FIG. 1 is a vertical cross-sectional explanatory view showing an embodiment of a magnet type attracting device of the present invention, and FIGS. 2 and 3 are partially enlarged explanatory views of a non-adsorbed object and an adsorbed object. The magnet type attracting device of FIG. 1 has the same basic configuration as the conventional magnet type attracting device shown in FIG. That is, the permanent magnet 3 serving as a magnetic field generation source is sandwiched between the pair of plate-shaped yokes 1 and 2 on one end side (upper end side in the figure). The contact surface with the object to be attracted (not shown) made of a magnetic material forms the magnetic pole surface for attraction.

Are arranged. As shown in FIG. 2, the prismatic synthetic rubber 40 has its tip portion (lower end portion in the figure) protruding from the magnetic pole surface for attraction, which is the tip portion of the pair of yokes 1 and 2 when the object to be attracted is not adsorbed. (T: amount of protrusion). Further, chamfered portions 41 and 42 are formed by grinding a predetermined amount on the inner portions of the tips of the pair of yokes 1 and 2, respectively.

る吸着を達成することとなる。When the magnet type attracting device is brought close to the object to be attracted 8 in this state, the tip of the prismatic synthetic rubber 40 first comes into contact with the object to be attracted 8 due to the attraction force of the attracting device.
As shown in FIG. 3, the tip end of the synthetic rubber 40 is slightly deformed and arranged in the chamfered portions 41 and 42 of the pair of yokes 1 and 2 to become substantially flush with the magnetic pole surface for attraction, and finally the pair of yokes. The attraction magnetic pole surfaces 1 and 2 come into contact with the object 8 to be attracted to achieve the desired attraction.

ことから従来に比べ大幅に増加する。In the magnet type attraction device having the above structure, the attraction force in the direction parallel to the attraction magnetic pole surface of the device is the attraction force in the direction perpendicular to the attraction magnetic pole faces of the pair of yokes 1 and 2. Generated by the synergistic effect of the frictional force due to the frictional force due to the elastic force acting in the direction perpendicular to the contact surface of the synthetic rubber 40 having a high friction coefficient with the object to be adsorbed 8 To increase.

成できなくなる。If the protrusion amount t of the synthetic rubber 40 from the magnetic pole surface for attraction is increased more than necessary, perfect contact between the magnetic pole surface for attraction of the pair of yokes 1 and 2 and the object to be attracted 8 is obstructed during attraction. As a result, a gap is formed between them to reduce the vertical attracting force. As a result, both the frictional force due to the vertical attracting force and the frictional force due to the elastic force of the synthetic rubber 40 are reduced. It becomes impossible to achieve an increase in the attraction force in the parallel direction.

The invention can be realized. Further, in the drawing, the contact surface of the synthetic rubber 40 with the object to be adsorbed 8 is shown as flat, but in order to obtain a larger frictional force, as described above, the contact surface has a predetermined unevenness. Forming a surface is also a desirable configuration.

A non-magnetic support member 51 to which is fixed is arranged via a leaf spring 52. As shown in the drawing, the tip end portion (lower end portion in the drawing) of the flat plate-shaped synthetic rubber 50 protrudes from the magnetic pole surface for attraction, which is the tip end portion of the pair of yokes 1 and 2 when the object to be attracted is not adsorbed. However, when the object to be attracted is adsorbed, the leaf spring 52 is deformed to be substantially flush with the attracting magnetic pole surface.
