Abstract

(57) [Summary] [Objective] The present invention aims to reliably take out rod-like or tubular works one by one. [Structure] Only one rod-shaped workpiece W is magnetically attached between a pair of magnetic material pieces 14 and 15 which are energized to the electromagnet 13 and are in contact with the electromagnet 13, and the outer sides of the magnetic material pieces 14 and 15 are attached. Provided is a work take-out device 11 in which non-magnetic bodies 16 and 17 are covered so that a work W is not magnetically attached.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a work take-out device for taking out rod-like or tubular works made of magnetic material such as iron one by one.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 3, there is provided a work picking device (1) in which a pair of magnetic material pieces (4,5) are brought into contact with the lower end of an electromagnet (3) housed in a case (2). ing. In the work take-out device (1), a large number of works W are produced by energizing the electromagnet (3) and magnetically sticking a rod-like work W made of a magnetic material such as iron to the magnetic material pieces (4,5). Only one work W is picked up from.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional work take-out device (1), only one work W is not necessarily magnetically attached between the magnetic material pieces (4,5), and it is particularly desirable to increase the magnetic attachment force. When one magnetic piece (4) is the N pole and the other magnetic piece (5) is the S pole, the work W is also magnetically attached to the outside of the magnetic pieces (4,5). It is easy and it is not possible to take out the work W one by one.

[0004]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention makes a pair of magnetic material pieces (14, 15) in contact with an electromagnet (13) face each other at a predetermined interval, and the magnetic material pieces (14, 15) are opposed to each other. The work picking device (11) is provided in which the outer side of (15) is covered with a non-magnetic material (16, 17).

[0005]

[Action]

 Only one rod-shaped work W made of a magnetic material is magnetically attached between the magnetic material pieces (14, 15) of the work extracting device (11) of the present invention. Since the non-magnetic material (16, 17) is coated on the outside of the magnetic piece (14, 15), the work W is magnetically attached to the non-magnetic material (16, 17) on the outside. Absent.

【Example】

 The present invention will be described with reference to an embodiment shown in FIGS. 1 and 2. An iron core (13A) having an H-shaped cross section and the iron core (13A) are wound around a case (12) of a work take-out device (11). An electromagnet (13) including a coil (13B) is housed, and a pair of left and right magnetic material pieces (14, 15) are in contact with the lower surface of the iron core (13A) of the electromagnet (13). The magnetic piece (14, 15) has an L-shaped cross section and is made of a magnetic material such as iron. The outside is covered with a non-magnetic material (16, 17) such as brass or plastic. 15) is fixed to the lower surface of the iron core (13A) of the electromagnet (13) by screws (20, 21) together with the non-magnetic material (16, 17) through the long holes (18, 19), The gap between the pieces (14, 15) can be adjusted according to the diameter of the work W.

In the work take-out device (11), when the coil (13B) of the electromagnet (13) is energized, one of the magnetic material pieces (14, 15) becomes an N pole and the other becomes an S pole. A rod-shaped work W made of a magnetic material such as iron can be magnetically attached between (14, 15). At this time, as shown in FIG. 2, the axis P of the work W is correctly aligned with the center line CL of the gap between the magnetic pieces (14, 15), so that the work take-out position is accurate. Further, since the work W is not magnetically attached to the non-magnetic material (16, 17) outside the magnetic material pieces (14, 15), only one work W is necessarily taken out.

When the work W is separated from the work take-out device (11), the electromagnet (13) may be energized or a reverse current may be instantaneously applied to the electromagnet (13). The N and S poles of the magnetic pieces (14, 15) are reversed and can be forcibly separated by the repulsive action of the magnetic force.

[0009]

[Effect of device]

 Therefore, in the present invention, it is possible to accurately take out the rod-shaped works one by one.
