Description

  The present invention relates to a wound core manufacturing apparatus, and more particularly, to a method for manufacturing a wound core made of a thin plate-like material.

  Since the core material corresponding to the top runner is supplied in a thin and long form (flat plate shape, width 100 to 300, thickness t 0.23 to 0.35), when configuring the iron core, It usually takes a shape.

  When manufacturing a wound core, conventionally, as shown in Patent Document 3, after a material is fed and cut, a predetermined number of a predetermined number of sheets are stacked while shifting the position in the longitudinal direction by a predetermined shift dimension. One laminated body block, stacked horizontally, wound around a core bar as an inner frame, and joined by butt joining (butt joining) or lap joining (overlap joining) at both ends of each laminated body block A rectangular wound iron core having a structure in which a step is arranged on one yoke part is manufactured. In addition, this process is performed consistently with one apparatus.

  An example from material feeding to lamination of a wound core is shown in FIG. Conventionally, the materials come into contact with each other at the time of feeding and stacking the materials, so that there is a problem that a resistance between the materials is generated due to friction or the like, resulting in a jam. The frequency of occurrence of jam increases from a material having a length of about 1100 mm or more (the conventional machine can manufacture up to 2000 mm or less).

  In the future, it will be necessary to cope with the large size and thinning of the material with the large-scale adaptation of the wound core, and it is necessary to support up to 4000 mm.

  Conventionally, in order to prevent this jamming, it has been necessary to slow down the material feeding speed or to assist the delivery to a fixed position by the operator as shown in FIG. For this reason, there was a problem of increased tact.

  As a countermeasure for preventing the winding iron core jam of the conventional long thin plate, there is a method of carrying and stacking using a conveyor and a magnetic body so that the materials do not come into contact with each other, as described in Patent Document 1, The conveyor and the magnetic material are difficult to suddenly brake, and are difficult to stack at a predetermined position at high speed, resulting in tact. Moreover, since the section until it is held by the conveyor and the section for dropping must be taken separately, there is a problem that leads to an increase in the size of the apparatus itself. Moreover, in patent document 2, it cannot respond about the thing from which a material width differs greatly, and the thing of falling from a center part is mentioned in the thing with a wide width | variety.

  In the present invention, two pairs of auxiliary hands are added to the material feeding and stacking unit. The auxiliary hand is started with a material feeding NC feeder shifted by a predetermined time, and is started in the middle of the material feeding. After that, it synchronizes with the feeding speed of the NC feeder and feeds the material while holding the material. In addition, by preparing two auxiliary hands, the movement from the gripping position to the feeding to the predetermined position is alternately operated, so that a significant time reduction can be expected. Further, the chuck portion of the auxiliary hand has a structure having a long claw-like object at the top and bottom, which is moved back and forth by an air cylinder to hold the material. When transporting a long object, it is held by the chuck of the auxiliary hand, sent out by the NC feeder, and pulled by the auxiliary hand. Moreover, it is also possible to carry in a form that is not held by the chuck but is hung on the nail under the auxiliary hand. The auxiliary hand can move in the vertical and horizontal directions according to the length and width of the material.

  That is, the present invention cuts a long thin plate into a predetermined size, shifts and stacks at a predetermined pitch, and in a wound core manufacturing apparatus that forms into an iron core shape, cuts the predetermined size and laminates it at the predetermined size. This is a wound iron core manufacturing apparatus having an auxiliary hand that moves at a conveying speed of the thin plate while gripping a thin plate.

  Further, according to the present invention, in the above-described wound iron core manufacturing apparatus, one auxiliary hand is provided on each side of the thin plate to be gripped, and when one auxiliary hand performs a feeding operation in the conveyance direction, The auxiliary hand is a wound core manufacturing apparatus that performs a returning operation without gripping.

  And this invention is the above-mentioned volume iron core manufacturing apparatus, The said auxiliary hand is provided one each on the both sides of the thin plate to hold | grip, When the auxiliary hands of both sides perform the feeding operation to a conveyance direction, It is a winding core manufacturing device that performs together.

  Furthermore, the present invention is the wound core manufacturing apparatus according to the above-described wound core manufacturing apparatus, wherein the auxiliary hand can be lifted while gripping the thin plate in a direction orthogonal to the thin plate to be conveyed.

  According to the present invention, after a long material is fed out and cut at a high speed with a thin plate, a predetermined length and a predetermined number of sheets are horizontally stacked while shifting the position in the longitudinal direction by a predetermined shift dimension, and a plurality of sheets are overlapped. It is possible. Since the auxiliary hand guides the material feeding and the movement to a predetermined position, the occurrence of jam can be drastically reduced even at a high speed operation. This eliminates maintenance time when a jam occurs. Ultimately, jam prevention and tact can be reduced.

FIG. 1 is a plan view of a top runner-compatible wound core manufacturing apparatus according to this embodiment. FIG. 2 is a side view of the apparatus. FIG. 3 shows an operation time chart of the present apparatus. The auxiliary hand 1 and the auxiliary hand 2 are provided on the left and right sides of the gantry 8 for placing the material. The long thin plate 6 as a material is fed at a high speed and a predetermined length from the previous process by the NC feeder 3, and when a predetermined time elapses, the auxiliary hand 1 and the auxiliary hand 2 start to operate. It operates while synchronizing. After that, when the predetermined dimension is reached, the thin plate 6 is cut by the cutting unit 4 and either the auxiliary hand 1 or the auxiliary hand 2 is horizontally shifted by a predetermined shift dimension in the longitudinal direction, and a predetermined number of sheets are horizontally placed on the gantry 8. stacked and go, the thin plate 6 which is stacked to a predetermined position in order to prevent the thin plate 6 at presser unit 7 is shift occurs due to the influence of the material between, but suppressed. At this time, the auxiliary hand 1 and the auxiliary hand 2 operate alternately between the predetermined material gripping position and the predetermined stacking position.

This unit is a part of the top runner-capable core manufacturing apparatus. As a whole, the top runner-capable core manufacturing apparatus is configured by stacking a plurality of thin plates 6 on the gantry 8 and then performing a post-process with a post-process hand. It is sent out and wound on a wound iron core.

  Details of the auxiliary hand 1 will be described. FIG. 4 shows a bird's eye view of the auxiliary hand 1. In this apparatus, the material is fed from the NC feeder 3 on the basis of the auxiliary hand 1 side. Therefore, the auxiliary hand 1 is less operated than the auxiliary hand 2.

  The operation of the auxiliary hand 1 is as follows. The operation in the material feeding (conveying) direction Y is guided by the LM guide 9a and the LM guide 9b, and the motor unit 10 and the rack 11 obtain the operation in the Y-axis direction. As an operation for holding the material of the auxiliary hand 1, first, the cylinder 12 is used as the Z-axis operation with respect to the step between the material delivery guide 5 and the gantry 8. A cylinder 13 is used to feed the material gripping portion 14 in the X-axis direction and perform an operation for avoiding the material. Finally, in order to hold the material, the chuck portion 15 is opened and closed by the cylinder 14.

  Next, details of the auxiliary hand 2 will be described. FIG. 5 shows a bird's-eye view of the auxiliary hand 2. In this apparatus, the auxiliary hand 2 has more operations than the auxiliary hand 1 in order to obtain a position that matches the predetermined width of the material.
