[0019]
Next, the configuration of the reverse transfer mechanism 30 which is the main part of the present invention will be described in detail with reference to FIGS. The reversing / transferring mechanism 30 is disposed adjacent to the transfer conveyor at the card reversing / transferring position, and as main mechanism members, a rotating cylinder 31 serving as a rotation driving means, reversing arms 32A and 32B, A power transmission means 33 for transmitting the rotation of the rotary cylinder 31 to the reversing arms 32A and 32B, an adsorption nozzle 34, and the like.
[0020]
More specifically, the rotary cylinder 31 has an output shaft 36 that can be rotated forward and backward, and is mounted on the apparatus main body base 29 via a frame 26. A timing pulley 37 is attached to the output shaft 36 so as to be integrally rotatable.
[0021]
The power transmission means 33 includes timing pulleys 39A and 39B which are attached to the sub-frame 26a via a bearing (not shown) so as to be rotatable with respect to the rotary shafts 38A and 38B, and timing pulleys 39A and 39B. 39A, 39B and an endless timing belt 40 that is wound around the outside of the timing pulley 37 and is integrally formed. The rotary shafts 38A and 38B are divided into left and right and are arranged in parallel to each other.
When the rotary cylinder 31 is rotated and the timing pulley 37 is rotated together with the output shaft 36, the power transmission means 33 transmits the rotation of the timing pulley 37 to the timing pulleys 39A and 39B via the timing belt 40. The timing pulleys 39A and 39B can be integrally rotated in the same direction, and the rotation shafts 38A and 38B are rotated together in the same direction by the rotation of the timing pulleys 39A and 39B.
[0022]
Of the reversing arms 32A and 32B, one arm 32A is attached to the other end of the rotating shaft 38A so as to be integrally rotatable, and the other arm 32B is attached to the other end of the rotating shaft 38B so as to be integrally rotatable. The two arms 32A and 32B have the same structure, except that the rotary shafts 38A and 38B attached thereto are different. Accordingly, the corresponding parts are described with the same reference numerals, and the arms 32A and 32B are bent in the middle to form a substantially square shape, and the tip side is offset from the rotary shafts 38A and 38B by a predetermined amount. At the positioned position, it is extended into the platen 9 on the chain 1 in a state parallel to the rotation shafts 38A and 38B. Each of the arms 32A and 32B has two suction nozzles 34, which are vacuum suction means attached to the brackets 41, with the bracket 41 fixed to the distal end side. The suction nozzle 34 sucks the card C on the platen 9 and holds it detachably.
The arms 32A and 32B and the suction nozzle 34 rotate 180 degrees according to the direction of rotation when the rotary cylinder 31 is rotated and the rotary shafts 38A and 38B are rotated integrally therewith. Yes. Further, as shown in FIG. 1, the suction nozzle 34 sucks the card C simultaneously with the rotation and rotates 180 degrees so that the back surface of the card C can be reversed to the upper surface. By operating simultaneously, the two cards C are also reversed at the same time. 1 and 3, the solid line and the alternate long and short dash line indicate the inverted state. After the reversal, the chain 1 is fed by the amount corresponding to the two platens 9 by the drive of the motor 16, that is, by two pitches.
[0023]
FIG. 4 is a flowchart showing an example of the operation procedure of the reverse moving mechanism 30 described above. Therefore, the operation of the peripheral structure of the reversing operation mechanism 30 will be described with reference to the flowchart shown in FIG.
First, when the sensors 28A and 28B detect that the two cards C have been transported to the position to be reversed, the detection signals are transmitted to the control unit 3 (steps S1 and S2). The rotary cylinder 31 is rotated by the control (step S3). Then, the timing pulley 37 attached to the output shaft 36 of the rotating cylinder 31 sends the timing belt 40 by a predetermined length according to the rotation direction, whereby the timing pulleys 39A and 39B are also rotated by a predetermined amount, and integrated with this. The rotary shafts 38A and 38B are rotated by half (180 degrees).
As a result, the arms 32A and 32B attached to the rotary shafts 38A and 38B rotate upward toward the lower surface of the card C on the platen 9 (step S4), immediately before the suction nozzle 34 comes into contact with the lower surface of the card C. The lower surface of the card C is vacuum-sucked to hold the card C, and the rotation is continued (step S5).
Further, the card C sucked and held by the suction nozzle 34 is reversed and transferred by two pitches on the conveyor by the rotation of the arms 32A and 32B as shown by a one-dot chain line in FIG. Is held on the conveyor facing up. This completes the inversion (steps S6 and S7).
Subsequently, the arms 32A, 32B after the card reversal rotate about 180 degrees from the position shown by the one-dot chain line in FIG. 1 to the position shown by the solid line by the reverse operation of the rotating cylinder 31, and wait at the return position. (Steps S8 and S9). And if it moves on a conveyor by 2 pitches and the new card | curd C is arrange | positioned on the suction nozzle 34, the same operation | movement will be repeated again.
Therefore, the card C sent to the position corresponding to the reverse transfer mechanism 30 is turned over in one operation via the arms 32A and 32B of the reverse transfer mechanism 30, and is transported again. Even an inspection device or a printing device can easily and rationally inspect the front and back surfaces (upper and lower surfaces) and print on the front and back surfaces (upper and lower surfaces).
[0024]
In the above embodiment, the structure for transmitting the rotational drive using the timing pulley (37, 39A, 39B) and the timing belt 40 is disclosed. However, this is not necessarily required, and for example, a combination of gears or the like is used. The rotation may be transmitted.
Moreover, although the case where the single-row chain 1 was used as the transfer conveyor has been described, it is not necessarily a single-row chain. For example, the holder 5 is attached to one side of the steel belt and the same as the case of the chain 1 is used. The platen 9 may be attached to the steel belt at the same interval, and a belt guide for positioning in the X and Y directions may be provided.
Further, the platen 9 may be provided so as to protrude in opposite directions from both sides of the chain.
Moreover, although the case where the card | curd C was handled was demonstrated, it is applicable not only when a card-shaped component etc. are conveyed, but being limited to a card | curd.
