品を除去している。 By the way, as one method for inspecting and removing products as good or defective, conventionally manufactured products are continuously fed to a belt conveyor, and the transported products are inspected by an inspection mechanism placed at a predetermined location on the belt conveyor. Inspect the product to identify good and bad products.
If the product is defective, the defective product is removed from the belt conveyor using mechanical removal means, such as an air cylinder, which is linked to the inspection mechanism.

共に、機械音による騒音が問題となつていた。 However, the above-mentioned mechanical removal means has a poor ability to follow the inspection mechanism's good/bad sorting operation, so in order to feed the products to the belt conveyor,
It is necessary to take precautions such as feeding at predetermined intervals or slowing down the speed of the conveyor, and noise caused by mechanical sounds has been a problem.

and a magnetic induction plate 7. The non-magnetic tube 5 is made of a non-magnetic material such as brass, and a coil 6 is wound around the non-magnetic tube 5. This coil 6 is located at a position P 1 a little distance apart in the axial direction from one end of the non-magnetic tube 5 (upper end in FIG. 2) and at a position P 2 at the other end of the non-magnetic tube 5 (lower end in FIG. 2). The coil 6 is wound around the non-magnetic tube 5, and the power supply circuit 3 is connected to the coil 6. The magnetic induction plate 7 consists of a center plate part 7a and a pair of side plate parts 7b, 7b hanging down from both ends of the center plate part 7a, and these are made of a magnetic material such as soft iron. A hole 8 having approximately the same diameter as the outside diameter of the non-magnetic tube 5 is bored in the center of the guide plate 7, and one end of the non-magnetic tube 5 is fitted into the hole 8. Therefore, the coil 6 is held by a magnetic induction plate 7, as shown in FIGS. 1 and 2.

流れる電流によつて決定される。 Therefore, the electromagnet structure 2 is arranged so that the other end P2 side of the non-magnetic tube 5 faces the conveyance surface of the belt conveyor, and the control circuit 4 is connected to a magnetic material or a material to be sorted which partially has a magnetic material. Part 9 (see Figure 2)
For example, if it is connected to an inspection mechanism that inspects washers, springs, resistors with magnetic caps, etc., it can be used to sort out whether the members 9 to be sorted are acceptable or defective after inspection. That is, the manufactured members 9 to be sorted are sequentially and continuously supplied to the conveyance surface of a belt conveyor, and the members 9 to be sorted conveyed by the belt conveyor are inspected by an inspection mechanism. If the inspection mechanism detects that the member 9 to be sorted is defective or non-defective, the inspection mechanism controls the control circuit 4.
The control circuit 4 determines timing so that the power supply circuit 3 is turned on when the member 9 to be sorted is conveyed substantially below the electromagnetic structure 2. When the power supply circuit 3 is turned on, a magnetic field H is generated within the non-magnetic tube 5 from the other end to one end of the non-magnetic tube 5, as shown in FIG. The member to be sorted 9 immediately begins to be attracted into the non-magnetic tube 5 by the electromagnetic force. Since the magnetic field H is largest at the center part 0 inside the non-magnetic tube 5, the member 9 to be sorted is gradually accelerated, and further decelerated as the member 9 to be sorted approaches the center part inside the non-magnetic tube 5. When the member 9 reaches the central part 0 in the non-magnetic tube 5, the member 9 to be sorted is attracted to the wall surface of the central part 0 in the non-magnetic tube 5 and stops (see FIGS. 2 and 4B). Therefore, the control circuit 4 controls the power supply circuit 3 at the point in time when the speed reaches the maximum while the material to be sorted 9 begins to be attracted, flies, reaches the center 0 in the non-magnetic tube, and stops.
When is turned off, the magnetic field H is no longer generated, and the member to be sorted 9 passes through the non-magnetic tube 5 due to inertia force and continues to fly above the non-magnetic tube 5 in FIG. , see Figure 4 A and B). Here, the timing at which the power supply circuit 3 is turned off by the control circuit 4 is as follows.
Although a timer or the like may be used, the value setting of the timer or the like is determined by the weight of the member 9 to be sorted and the current flowing through the coil 6.
そして、非磁性管５内から飛び出した被選別部
材の飛行領域に、ダクト、案内板等を配しておけ
ば、任意に被選別部材９の飛行方向を変えること
ができ、所定場所に不良品又は良品としての被選
別部材９を導くことができる。 If a duct, a guide plate, etc. are placed in the flight area of the materials to be sorted that fly out from inside the non-magnetic tube 5, the direction of flight of the materials to be sorted 9 can be changed arbitrarily, and defective products can be placed in a predetermined place. Alternatively, the members 9 to be sorted can be guided as non-defective products.
上記方法を実施する一具体例を示せば、被選別
部材９が数100ｇ以下のときにはコイル６に流す
電流は1.5A、電流回路４による電圧は45V通電時
間20ｍｓあれば足りる。被選別部材９の重量、大
きさが変わつた場合には、上記各値、装置１の大
きさを、適宜変えればよいのは勿論のことであ
る。 To give a specific example of carrying out the above method, when the member to be sorted 9 weighs several hundred grams or less, it is sufficient to apply a current of 1.5 A to the coil 6 and a voltage of 45 V from the current circuit 4 for a duration of 20 ms. Of course, if the weight and size of the member 9 to be sorted change, the above values and the size of the device 1 may be changed as appropriate.
以上一実施例について述べたが本発明にあつて
は、磁性体と非磁性体とからなる混合材において
の選別等、特許請求の範囲から逸脱しない範囲で
広く有効に利用できるものである。尚、「選別」
の概念には、特定の磁性体について一の場所から
他の場所へ移動させる広い概念が含まれるものと
する。 Although one embodiment has been described above, the present invention can be widely and effectively used for sorting mixed materials consisting of magnetic and non-magnetic materials without departing from the scope of the claims. In addition, "selection"
The concept includes the broad concept of moving a specific magnetic substance from one location to another.

とを利用するだけなので、次のような効果を奏す
る。(Effects of the Invention) As described above, the present invention merely utilizes the electromagnetic force and the inertia force caused by the flight of the object produced by the action of the electromagnetic force, and therefore has the following effects.

構によく見られるアーム、プランジヤー等、機
械的な負荷となる貫性モーメントがないのでス
ピードに対する追従性がよくなると共に、被選
別部材を所定場所に簡単に導くことができる。 Since there is no penetrating moment that causes a mechanical load on the arms, plungers, etc. that are often found in conventional sorting mechanisms for the sorting operation of the parts to be sorted, it is possible to follow the speed better, and it is easy to place the parts to be sorted in the designated place. can lead to.
