Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a resistance value sorting device that can efficiently classify resistors having metal caps at both ends according to their resistance values while transporting the resistors.

A conventional resistance value classification device of this type will be explained with reference to FIGS. 1 and 2. First, in the figure, reference numeral 1 denotes a main body base, and on the concentric circle of this base 1, there are a plurality of (six in this embodiment) resistor extraction ports 2 for taking out resistors at arbitrary angles according to the resistance value. are arranged at equal intervals. Reference numeral 3 denotes a disk body 5 which is rotatably mounted on a rotating shaft disposed in the vertical direction of the body base 1.
and a disk cover 6 fixed to the upper surface of the disk body 5 with screws.The table disk 3 is constructed by a drive gear in which a part of the disk body 5 is driven by a motor (not shown). 4, and the table disk 3 is configured to rotate intermittently. A protective metal plate 7 is attached to the upper surface side of the peripheral edge of the disk cover 6 constituting the table disk 3 by suitable means such as screwing.
The peripheral edge of the disk cover 6 to which the protective metal plate 7 is attached is adapted to rotate above the resistor outlet 2 of the main body base 1 with a slight gap. The resistor outlet 2 is provided at the peripheral edge of the disk cover 6 including the protective metal plate 7.
Resistor insertion holes 8 are provided around the entire circumference on the same circumference and at the same intervals as the outlet 2, and a resistor (not shown) is inserted into this insertion hole 8. A protective metal plate 7 protects the disk cover 6 during insertion. A plurality of shutters 9 are provided so as to be located in the gap between the resistor outlet 2 and the peripheral edge of the disk cover 6, and each of the shutters 9 is driven by a solenoid 10 to retreat and close the resistor outlet 2 and the disk cover. The space between the outer edge and the peripheral edge of 6 is opened.

Now, the table disk 3 is being intermittently rotated one pitch at a time, and the resistor is inserted into the resistor insertion hole 8 at an appropriate position where the resistor outlet 2 is not present.
The resistor is being transported. At this time, the main body base 1
Needless to say, the resistor is constructed in a shape that prevents the resistor from falling through the insertion hole 8. The plurality of solenoids 10 are configured to operate according to the resistance value range of the resistor, and when the resistor is transported into the insertion hole 8, the solenoid 10 at a predetermined location is operated and the resistor is shut down. 9 is opened, it falls into the outlet 2 corresponding to a predetermined resistance value range. This allows the resistors to be classified according to their resistance values while being transported.

With this conventional sorting device, the number of classifications cannot be increased because the solenoid takes up a large amount of space, and since the shutter reciprocates, the rotation speed of the table disk cannot be made very fast, and it is very noisy. Moreover, it had disadvantages such as mechanical deterioration such as wear and tear on the shutter drive unit and the surface of the main body base on which the shutter slides.

The present invention has been made to eliminate the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to FIGS. 3 to 5.

First, in the figure, reference numeral 11 denotes a main body base, and on the concentric circle of this base 11 there are a plurality of outlets 12 (14 in this embodiment) for taking out resistors at arbitrary angles according to their resistance values. A take-out guide 13 is provided. Reference numeral 14 denotes a disk body 16 which is rotatably mounted on a rotating shaft 15 disposed in the vertical direction of the body base 11, and a disk cover made of an insulating material which is fixed to the upper surface of the disk body 16 with screws. 17, a part of the disk body 16 of the table disk 14 is engaged with a gear 18 driven by a motor (not shown), and the table disk 14 is rotated intermittently one pitch at a time. Configured for exercise. A disk cover 17 that constitutes this table disk 14
A protective metal plate 19 made of a non-magnetic material such as a stainless steel plate is attached to the upper surface side of the peripheral edge of the disc cover 17 by an appropriate means such as screwing. The main body base 11 is taken out and rotated above the guide 13 with a slight gap. The ejection opening 1 is located at the peripheral edge of the disk cover 17 including the protective metal plate 19.
Resistor insertion holes 20 are provided around the entire circumference on the same circumference as 2 and at the same intervals as the outlet 12, and a resistor having a metal cap at both ends is provided in this insertion hole 20. A protective metal plate 19 protects the disk cover 17 when the disk cover 21 is inserted. Reference numeral 22 denotes an electromagnet holding plate fixed to the main body base 11 with screws or the like so as to be installed with a slight gap above the portion of the table disk 14 provided with the outlet 12. It is made of metal that does not carry any stains. This electromagnet holding plate 22 has the same number of coils 23 facing the extraction guide 13.
An electromagnet 25 consisting of an iron core 24 is fixed by a mounting bracket 26, and the tip of the iron core 24 is installed in a recess 27 formed in the electromagnet holding plate 22 with a slight thickness left, and A cross-shaped groove 24' is provided at its tip to strengthen the magnetic force.

Now, the table disk 14 is being rotated intermittently by one pitch (distance between adjacent insertion holes 20), and the resistors 21 are sequentially inserted into the resistor insertion holes 20 at appropriate positions where there is no outlet 12. The container 21 is being transported. It goes without saying that the main body base 11 is configured in a shape that prevents the resistor 21 from falling through the insertion hole 20 when this outlet is not present. On the other hand, a large number of electromagnets 25 are operated simultaneously. Therefore, the metal part (cap part) of the resistor 21, which has entered the insertion hole 20 above the outlet 12 and is transported by the table disk 14, is magnetically attached to the iron core 24 (actually, the electromagnet holding plate They are attracted to and come into contact with the lower surface of the recess 27 of 22, and are transported one pitch at a time without falling from the outlet 12. At this time, a closed loop is formed between the electromagnet 25, the metal part of the resistor 21, the electromagnet holding plate 22, and the mounting bracket 26, so that the resistor 21 is magnetized. The plurality of electromagnets 25 are configured to momentarily cut off their operation according to the resistance value range of the resistor 21, and are configured to operate at any time after insertion into the insertion hole 20 until the first electromagnet 25 is placed. The resistor 21 whose resistance value has been measured at the point in time is transported without falling to the electromagnet 25 which stops operating within the corresponding resistance value range. The resistor 21 that has been transported to the electromagnet 25 corresponding to the corresponding resistance value range is separated from the iron core 24 when the operation of the predetermined electromagnet 25 is cut off, and instantaneously moves away from the extraction port of the extraction guide 13. He will be dropped to 12. At this time, since the electromagnet holding plate 22 and the protective metal plate 19 are made of materials that do not have residual magnetism (are not magnetic), the electromagnets 25 on both sides of the predetermined electromagnet 25 whose operation has been cut off are If the low resistor 21 does not fall due to residual magnetism, there will be no inconvenience at all. By configuring the electromagnets 25 provided in large numbers in this way to cut off their operation according to the resistance value range,
The low resistance resistors 21 that have been transported one pitch at a time are dropped into the outlet 12 within a predetermined resistance value range, and the resistors 2
1 can be classified.

The present invention is constructed as described above, and since the electromagnet is small, it is possible to attach a large number of electromagnets, and a large number of classifications can be achieved. Furthermore, since it uses electromagnets, there is no mechanical deterioration phenomenon, and no noise is generated. Furthermore, it is possible to provide an apparatus that performs effective sorting operations, such as increasing the rotation speed of the table disk.
