As shown in FIG. 2, the pushing portion 61 is provided above the box 42, and has a push rod 63 which moves up and down by an air cylinder 62, and is attached to the tip of the push rod 63 and abuts on the pad 1. And a pad holder 64.

Next, referring to FIG. 8 and FIG.
1 will be described. The bag mounting table 72 is provided on the side of the storage section 41, and a plurality of pad storage bags 73 are stacked horizontally and can be moved in the center direction. Note that a guide 72a for regulating the position around the pad storage bag 73 is provided. The first suction unit 74 includes a base 75 on which a shaft 75
A is pivoted 90 degrees about A, and is reciprocally movable in the horizontal direction toward the center of the storage section 41.
Each of the suction cups A76 is attached. These suckers A7
6 is fixed to the base 75 by a screw penetrating the long hole, and if this screw is moved along the long hole, the suction cup A
The spacing between 76 can be changed.

The second suction part 77 is located on the opposite side of the storage part 41 from the first suction part 74, and is provided so as to be able to reciprocate in the horizontal direction. Two suction cups B78 are attached to the second suction section 77. These correspond to the suction cup A76 located at the center of the first suction section 74.
Further, the pad storage bag 73 is located below the storage section 41.
A pair of bag holding plates 79, which are in pressure contact with the inner surface of the bag, are provided so as to be vertically movable and horizontally movable. A chute 80 is provided below the storage section 41, and a pad unloading cylinder 81 for discharging a plurality of pats 1 packed in a bag is attached to a base of the chute 80.

Next, the operation of the above configuration will be described. First Step The pad material 2 is set in each of the left and right lower molds 12. Second Step The upper mold 13 is lowered to heat and compress the pad 2 to simultaneously form the pad 1 for the left shoulder and the pad 1 for the right shoulder.

Third Step When the upper mold 13 rises, the transfer unit 21 moves above the lower mold 12 from the standby position. Below the outlet 44 of the storage section 41, a pad storage bag 73 is suspended with its upper end opened. The swing arm 26 descends, and the left and right gripping devices 3
1 is operated to simultaneously grasp the pad 1 for the left shoulder and the pad 1 for the right shoulder in the lower mold 12 and move up.

Fourth Step (See FIG. 10) The transfer section 21 moves above the storage section 41. Sensor 51
Detects the pad 1, the swing arm 26 descends and the pad 1 for the right shoulder is inserted into the box 42. Then, the gripper 31 is released, and the pad 1 for the right shoulder is placed on the tray 46. Since the presser bar 53A presses the pad 1 for the right shoulder when the swing arm 26 moves up, the pad 1 for the right shoulder remains on the tray 46. In addition, the pad storage bag 73 is hung below the discharge port 44 of the storage unit 41 with its upper end opened. (See Fig. 11)

Fifth Step The first detector 52 detects insertion of the pad 1, and the counter 55 counts the number of stored pads 1. Sixth step (see FIG. 12) The turning arm 26 of the transfer unit 21 rotates 180 degrees to
After the direction of the pad 1 has been changed, the pad 1 descends, and the pad 1 for the left shoulder is inserted into the box 42 as in the fourth step.
The pad 1 for the left shoulder is placed on the pad 1 for the right shoulder inserted in the fourth step by the release of the gripping device 31. At this time, left
The neck part 1b of the right pad 1 is overlapped with the shoulder part
1a is located in the opposite direction. When the swing arm 26 moves up, the presser bar 53B presses the pad 1 for the left shoulder, and the pad for the left shoulder remains on the tray 46. The transfer unit 21 returns to the standby position.

Seventh Step When the transfer unit 21 returns to the standby position, the tray 46 is lowered by a predetermined height (the height of one set of pads 1). And
At the upper end of the box 42 is formed a space into which a set of pads 1 can be inserted. Eighth step The first to seventh steps are repeated.

Ninth Step (Refer to FIG. 13) When a predetermined number (10 sets) of the pads 1 are stored in the storage section 41, the counter 55 detects it, moves the tray 46 backward, and opens the discharge port 44. You. Push rod 6 of pushing part 61
3 descends, and the pad presser 64 pushes down the stored pad 1. The pad 1 descends along the inclined portions of the pair of bag guide plates 53 and is pushed into the pad storage bag 73. When the bag holding plate 79 moves inward, the ten sets of pads 1 fall onto the lower chute 80 together with the pad storage bags 73.

Tenth Step The push rod 63 is raised to the original position. The receiving tray 46 returns to the original position, and the discharge port 44 is closed. Eleventh Step The pallet unloading cylinder 81 operates and the chute 80
The plurality of pats 1 packed in the upper bag are carried out to the tip of the chute 80. The twelfth step (see FIG. 14) The bag mounting table 72 advances, and the suction cup A76
Suck one piece. When the suction cup A76 rotates 90 degrees, the pad storage bag 73 is suspended in a vertical state as shown by a two-dot chain line.

A thirteenth step (see FIG. 15) The suction cup A 76 and the pad storage bag 73 advance to below the center of the storage section 41. The suction cup B78 on the opposite side also moves forward and sucks the pad storage bag 73 from both sides as shown by the two-dot chain line. Fourteenth Step When the suction cups A76 and B78 recede, the pad storage bag 7
The top of 3 opens. Then, the bag holding plate 79 waiting above is lowered once, and as shown in FIG.
3 is pressed against the inside, and suspended with its upper end open.
Then, the bag holding plate 79 moves up to the original position again. Further, the pair of bag guide plates 53 is rotated, and the tips are inserted into the pad storage bag 73. Then, the process returns to the first step.

According to the above embodiment, the following effects can be obtained. Since the operation of packing the ten sets of pats 1 into the pad storage bags 73 from the molding of the pats 1 is automatically performed consistently, the combination of the left and right pats and the bag stuffing by manual operation are performed as in the related art. Need not be performed, and productivity can be significantly improved. 2. Since the discharge port 44 of the storage section 41 is closed by the tray 46, the pads 1 inserted from the insertion port 43 are stacked and stored. Further, when a predetermined number of pats 1 are inserted, the tray 46 is retracted to open the discharge port 44, so that the pats 1 are continuously inserted, stored, and discharged, and the production amount is increased.

3. The storage section 41 stores the pad 1 at the upper end of the box 42 because the first detecting section 52 detects the insertion of the pad 1 and lowers the tray 46 by a predetermined distance. Space is secured, and insertion of the pad 1 is reliably performed. 4. Since the grippers 31 are provided at both ends of the turning arm 26 in the transfer unit 21, the pads 1 for the left and right shoulders can be taken out at the same time. 5. The gripping device 31 pierces the two parallel gripping needles 34 into the pat 1, and the driving unit 36 expands the tips of the two gripping needles 34, so that the pat 1 can be reliably gripped and released. It is performed smoothly, and the pad 1 is not damaged.

6, since the swiveling arm 26 is configured to be rotatable, the pads 1 can be alternately stacked, and the thick portions do not overlap, so that the volume of bag packing can be reduced. 7. The pad storage bag 73 is continuously supplied from the bag supply unit 71 to the lower side of the storage unit 41 with the upper end opened, so that a continuous operation can be performed.
