[7] The upper blade 35 and the lower blade 36 are moved in the left-right direction (see f in FIG. 4). In the moving state of the upper blade 35, a work space in which the operator can insert a finger is formed on the remaining cut surface 38 of the strip steel plate 11 and the cut surface 38 of the new strip steel plate 11. In the moving state, an entry space into which the joining base 37 can enter is formed under the remaining cut surface 38 of the strip steel plate 11 and the cut surface 38 of the new strip steel plate 11.
[8] The joining base 37 is moved up and down and left and right to enter the entry space from below, and contact the lower surface of the remaining strip-shaped steel plate 11 and the lower surface of the new strip-shaped steel plate 11 from below (FIG. 4 f).
[9] The operator inserts fingers into the work area from above, and affixes the adhesive tape 41 on the upper surface of the remaining strip-shaped steel plate 11 and the upper surface of the new strip-shaped steel plate 11 (see f in FIG. 4). As shown in FIG. 5A, the adhesive tape 41 is applied obliquely along the cut surface 38 of the remaining strip-shaped steel plate 11 and the cut surface 38 of the new strip-shaped steel plate 11, and the remaining tape The strip steel plate 11 and the new strip steel plate 11 are joined via an adhesive tape 41. As shown in FIG. 6, this adhesive tape 41 is a non-magnetic one in which an acrylic transparent adhesive 43 is applied to a polyester film 42, and the width dimension in the left-right direction is set to 10 mm. The film 42 of the adhesive tape 41 is colored and opaque, and is set in a color different from that of the remaining strip-shaped steel plate 11 and the new strip-shaped steel plate 11. This adhesive tape corresponds to a tape.
[10] The front upper clamp 31 and the front lower clamp 32 are moved up and down to release the remaining strip steel plate 11, and the joining base 37 is moved up and down and left and right. Return to. The rear lower clamp 33 and the rear lower clamp 34 are moved up and down to release the new strip steel plate 11, and the rear lower clamp 33 and the rear lower clamp 34 are moved up and down to the initial position. Return to. Accordingly, in response to the operation of the feeder 14, the remaining strip steel plate 11 and the new strip steel plate 11 are integrally conveyed in the direction of the arrow X, and the operator has to set the new strip steel plate 11 on the feeder 14 and the like. The new strip-shaped steel plate 11 is sequentially conveyed to the processing stages S1 to S6 of the press machine 15 following the remaining strip-shaped steel plate 11 without being hung, and the processing stages S1 to S6 are applied to the new strip-shaped steel plate 11 following the remaining strip-shaped steel plate 11. Shearing is performed in order.

According to the said Example 1, there exists the following effect.
A new strip-shaped steel plate 11 is attached to the remaining strip-shaped steel plate 11 by applying an adhesive tape 41 between the end of the remaining strip-shaped steel plate 11 on the side opposite to the arrow X direction and the end of the new strip-shaped steel plate 11 on the arrow X-direction side. Joined. For this reason, in response to the remaining strip steel plate 11 being conveyed in the direction of arrow X by the feeder 14, a new strip steel plate 11 is supplied to the press machine 15 following the remaining strip steel plate 11, and the remaining strip steel plate 11 is supplied to the remaining strip steel plate 11. Since the new strip-shaped steel plate 11 is continuously pressed by the press 15, the amount of waste material is reduced and the time required for setup is also reduced. In addition, the decrease in tensile strength and the occurrence of strain, which are problems when welding thin steel strips 11, are eliminated. Accordingly, the transport strength of the strip steel plate 11 is improved, and the strip steel plate 11 is transported smoothly.

  Since the nonmagnetic adhesive tape 41 is used as a tape for joining the remaining strip steel plate 11 and the new strip steel plate 11, unlike the case of using aluminum tape as the tape, the stator punched plate 3 and the rotor punch Magnetic punching waste does not adhere to the punched plate 8. Therefore, when the stator core 1 is manufactured by stacking the stator punched plates 3, the quality of the stator core 1 is stabilized, and the rotor core 2 is manufactured by stacking the rotor punched plates 8. In this case, the quality of the rotor core 2 is stabilized.

  Since the adhesive tape 41 having a color different from that of the belt-like steel plate 11 is used as a tape for joining the remaining belt-like steel plate 11 and the new belt-like steel plate 11, it is visually checked whether or not the adhesive tape 41 is accurately applied to the target position. It becomes easy to confirm with.

  By cutting the respective end portions of the remaining strip-shaped steel plate 11 and the new strip-shaped steel plate 11 with the upper blade 35 and the lower blade 36, the remaining strip-shaped steel plate 11 and the new strip-shaped steel plate 11 are each provided with an inclined cut surface. 38 was formed, and an adhesive tape 41 was stuck between the remaining strip-shaped steel plate 11 and the new strip-shaped steel plate 11 in a direction along the two cut surfaces 38. Accordingly, since the adhesive surface of the adhesive tape 41 to the remaining strip-shaped steel plate 11 and the adhesive surface to the new strip-shaped steel plate 11 are increased, the bonding strength between the remaining strip-shaped steel plate 11 and the new strip-shaped steel plate 11 is increased. Moreover, the adhesive tape 41 gradually passes between the upper roller 18 and the lower roller 19 (see FIG. 5). Accordingly, since the force acting on the adhesive tape 41 from the upper roller 18 and the lower roller 19 is dispersed, the adhesive tape 41 is prevented from being peeled off when passing between the upper roller 18 and the lower roller 19.

  Since the adhesive tape 41 is affixed between the upper surface of the remaining strip-shaped steel plate 11 and the upper surface of the new strip-shaped steel plate 11, it becomes easier for the operator to insert the hand into the work space from above and apply the adhesive tape 41.

  After the curl of the new strip steel plate 11 was corrected by the leveler 13, the remaining strip steel plate 11 and the new strip steel plate 11 were joined with the adhesive tape 41. Accordingly, since the adhesive tape 41 does not pass through the plurality of leveler rollers of the leveler 13, the adhesive tape 41 is not peeled off by the force when passing through the plurality of leveler rollers.

  Since the gap 39 is formed between the two cut surfaces 38 when the remaining belt-like steel plate 11 and the new belt-like steel plate 11 are joined with the adhesive tape 41, the case where the two cut surfaces 38 are brought into contact with each other is different. The remaining strip-shaped steel plate 11 and the new strip-shaped steel plate 11 are not joined in a “<” shape. Therefore, the remaining strip steel plate 11 and the new strip steel plate 11 are smoothly conveyed to the press machine 15.

  FIG. 7 shows how the press machine 15 processes the remaining strip-shaped steel plate 11 and the new strip-shaped steel plate 11, and the adhesive tape 41 is stamped on the stator at the processing stage S5. By being punched together with the plate 3, it falls into the die D5 of the lower die 21, and the stator punched plate 3 to which the adhesive tape 41 is attached is discarded without being used as a product. That is, the adhesive tape 41 is affixed to a portion of the remaining strip-shaped steel plate 11 and the new strip-shaped steel plate 11 that is punched as the stator punching plate 3 and is not punched as the rotor punching plate 8. Affixed.

According to the said Example 2, there exist the following effects.
The adhesive tape 41 avoids the portion where the rotor punched plate 8 is punched out of the end of the remaining strip-shaped steel plate 11 on the side opposite to the arrow X direction and the end of the new strip-shaped steel plate 11 on the arrow X direction side. Was affixed. Accordingly, since a large number of rotor punched plates 8 can be punched from the remaining strip steel plates 11 and new strip steel plates 11, the number of stacked rotor punched plates 8 is equal to the number of stacked stator punched plates 3. However, the required number of stator punched plates 3 and the required number of rotor punched plates 8 can be secured with a small number of strip-shaped steel plates 11.

  As shown in FIG. 8, a plurality of positioning holes 40 are formed in each of the remaining strip-shaped steel plate 11 and the new strip-shaped steel plate 11. The plurality of positioning holes 40 of the remaining strip steel plate 11 are arranged in a line along the cut surface 38 of the remaining strip steel plate 11, and the plurality of positioning holes 40 of the new strip steel plate 11 are cut from the new strip steel plate 11. Positioning pins are inserted into the plurality of positioning holes 40 of the remaining strip-shaped steel plates 11 and the plurality of positioning holes 40 of the new strip-shaped steel plates 11, which are arranged in a line along the surface 38.

  The plurality of positioning pins are fixed to the joining table 37, and are inserted into the positioning holes 40 when the joining table 37 enters the entry space. The plurality of positioning pins serve to restrain each of the remaining strip-shaped steel plate 11 and the new strip-shaped steel plate 11 so as not to move to the target positions. The remaining strip steel plate 11 and the new strip steel plate 11 are prevented from shifting when the adhesive tape 41 is affixed. Each of the plurality of positioning pins escapes from the positioning holes 40 of the remaining strip-shaped steel plate 11 or the positioning holes 40 of the new strip-shaped steel plate 11 when the joining base 37 is moved to the initial position.

In the first to third embodiments, an aluminum tape may be used instead of the nonmagnetic adhesive tape 41.
In the first to third embodiments, the adhesive tape 41 may be automatically attached between the remaining strip steel plate 11 and the new strip steel plate 11 by a robot or the like.

In the first to third embodiments, a product different from the stator punching plate 3 and the rotor punching plate 8 may be punched from the strip steel plate 11.

  As mentioned above, although the Example of this invention was described, this Example is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
