The cutting part 60 is installed as a mandrel of the working blade 62-1 and the fixed blade 63 to the shaft 64 on the support 61 as shown in FIG. -1) is connected to the rod (67-1) and the shaft (66) of the cylinder (67) fixed to the support (61) by passing through the distribution hole (65) on the upper end of the working piece (62) integrally will be.

The operation relationship will be described below. The cathode 4 is fixed to the plate 3 on which the cathode 4 is fixed, and the cathode 4 is transported by an arbitrary conveying means and stopped, and the morph staple 5 wound in a roll is rolled by a motor. By a feeding device such as rotation of a predetermined length is drawn out. The mole strip 5 to be drawn out is connected to one surface by the guide piece 33 of the support bar 32 which is fixed by a fixing means such as the fixing frame 11 to maintain the connection state. 33 is held in the state between the grip pieces 46 and 47 of the tape holding arm 40 at the upper and lower sides.

In this state, when the cylinder 50 of the tape holding arm 40 is operated to discharge the rod 50-1, the operating piece 48 is rotated about the shaft 52 and thus the operating arm 45 is retracted. The gripping piece 47 on the working arm 45 side grips the mole staple 5 drawn out while abutting on the gripping piece 46 on the fixed arm 41 side.

After the gripping pieces 46 and 47 of the tape gripping arm 40 hold the mole-stape 5, the cutting portion 60 as shown in FIG. Cut off.

As the rod 67-1 is discharged by the operation of the cylinder 67, the mandrel 62 which is installed on the shaft 64 is rotated, so that the operating blade 62-1 moves toward the fixed blade 63. The morph staple 5 inserted in between is cut.

After the cutting is completed, as shown in FIG. 5, when the cylinder 13 operates to draw in the drawn rod 13-1, the movable table 20 moves together with the support 12. In addition, the molten staple 5 held by the tape holding arm 40 also moves to match the cathode 4 of the stationary pole plate 3.

After the movement of the movable table 20 is completed, as shown in FIG. 7, the cylinder 24 fixed to the support 12 operates to draw the rod 24-1 long. When the rod 24-1 is pulled out, the movable table 20 moves forward. At this time, the roller 22 mounted on the support plate 21 is rolled on the guide bar 17, and the guide rod 19 is attached to the support 12. Since the sliding movement in the fixed guide pipe 18, the moving table 20 is advanced in the forward direction.

In addition, when the moving table 20 moves forward, the roller 29 moves together with the tape holding arm 40 holding the mole staple 5, and the moving table 20 is progressively advanced, thereby holding the tape. Since the roller 29, which is installed on the arm 40, is gradually approached along the narrow guide groove 31, the tape gripping arm 40 is close to each other while the grip pieces 46 and 47 stop. It moves to the inside of the upper and lower sides of the pole plate 3 which is made.

In this manner, when the grip pieces 46 and 47 of the tape gripping arm 40 are moved closer and inward to each other, the morph staple 5 held by the grip arms 46 and 47 is the cathode 4. It is adhered to the upper and lower surfaces of the electrode plate 3 while covering the. When the movable table 20 is fully advanced and the grip pieces 46 and 47 of the tape grip arms 40 are moved inwards almost deeply, the cylinder 50 of each tape grip arms 40 operates to hold the grip state. Will be released.

The gripping state of the mole staple 5 is a state in which the rod 50-1 of the cylinder 50 is pulled out, and in this state, the cylinder 50 is operated in reverse to advance the rod 50-1. Since the piece 48 is rotated to push the operating arm 45, the holding piece 47 of the operating arm 45 is spaced apart from the holding piece 46 of the fixed arm 44 of the mole staple 5. The gripping state is released.

After the movement of the movable arm 20 and the tape grip arm 40 by the operation of the cylinder 24, the mole staple 5 is attached, and then the cylinder 24 is operated in reverse to move the movable arm 20 and the tape. When the gripper 40 is retracted, the tape grippers 40 which are retracted are moved while their rollers 29 are re-expanded again along the guide hole 31 of the adhesive guide guide 30.

When the movable table 20 is retracted, the push bar 34 fixed to the movable table 20 is stopped by the stopper 35, thereby stopping the shock.

When the movable table 20 is moved, the mole-staff 5 maintains a state in which the ball is supported by the guide piece 33 of the support bar 32 by a predetermined length again on the roll. As described above, the movable table 20 which is retracted in the state in which the morph staple 5 is pulled out again moves to the right side from the bonding position while the rod 13-1 is drawn out by the operation of the cylinder 13. When the movable table 20 is turned to the right, the morph staple 5 is introduced between the holding pieces 46 and 47 of the opened tape gripping arm 40. After the molten staple 5 is bonded to the pole plate (3) is discharged by any conveying means and a new pole plate (3) is supplied and stopped after the automatic self-adhesive device 10 according to the present invention 10 This is repeated.

According to the present invention configured and operated as described above, the tape grip arm 40 moves the top and bottom of the pulled-out mole staple 5 when the mole staple 5 is fed by a predetermined length in a state in which the mole staple 5 is swallowed in a roll shape. By holding the plate and cutting the gripped upper side, and then moving the movable table 20, a series of processes for attaching the cut morph staple 5 to the stationary pole plate 3 automatically are carried out. As a result, productivity can be improved, and accordingly, the adhesion state can be maintained uniformly, thereby improving the reliability of the quality.

In addition, if the position where the mole-stape is supplied and the position where it is held by attaching it is different from each other, it can be carried out continuously without interrupting work. Therefore, the text type for attaching the mole-stape 5 can be shortened. This can improve efficiency and thus further increase productivity.

In particular, when moving the movable table 20 forward and backward in the molten-stap automatic adhesive device 10 according to the present invention, the tape holding arm (40) holding the molten-stape (5) is close to each other or spaced apart, Since the tape gripping arm 40 is seen, the mole-staff 5 is automatically attached to the pole plate 3, and when retracted, it is filled with each other in a close state, almost similar to artificial attachment. It can be attached to a degree enough to improve the reliability of the adhesion.
