Each slide base 21 is provided with a rodless cylinder 24 in parallel with the support rails 22, and a base end portion of each slide hand 23 is engaged with the rodless cylinder 24 (FIG. 2).
[0017]
As described above, the supply device 13 is opposed to the linear traveling portion of the endless chain 5 of the printing unit 1, and the swivel lifting platform 20 is configured such that its slide base 21 moves in the traveling direction of the endless chain 5. It is designed to rotate intermittently. The slide bases 21 are sequentially stopped in a posture that is parallel to the traveling direction of the endless chain 5. Further, the other slide table 21 faces the sub table 11 in this stopped state. The slide hand 23 is positioned on the moving center of the transport table 6 in which the CD adsorber 18 moves as the endless chain 5 travels with the slide table 21 facing the endless chain 5. At this time, the CD adsorber 18 of the slide hand 23 supported by the slide table 21 on the opposite side faces the sub table 11.
[0018]
A bracket 25 is provided downward on the slide hand 23 of the supply device 13, and the bracket 25 abuts on a dog 26 protruding from the side surface of each transport table 6 of the printing unit 1. The carriage 6 moves in synchronization with the travel of the endless chain 5. In this state, the center of the CD adsorber 18 of the slide hand 23 and the center of the recess 28a of the cradle 28 coincide with each other. Then, after moving over a predetermined distance, the slide table 21 rises. Thereafter, the swivel lift 20 is intermittently swung in the direction of the arrow (the travel direction of the endless chain 5), whereby the bracket 25 and the dog 26 are released from contact and the slide hand 23 is stopped. The slide hand 23 is moved in the reverse direction by the rodless cylinder 24 (FIGS. 3 and 4).

Then, the CD is supplied from the supply unit 3 a of the supply / discharge device 2 to the recess 28 a of the receiving table 28 of each conveyance table 6 in the downstream portion of the straight traveling unit on the return path side. The carriage 6 to which the CD is supplied is screen-printed by the first screen printing machine 9a in the straight traveling section on the return path side, and then the first, second, third, and fourth in the straight traveling section on the outbound path side. Offset printing is performed by each rotary printing machine 8a, 8b, 8c, 8d, and screen printing is further performed by the second screen printing machine 9b. Each printed CD is sequentially discharged by the discharge unit 3b of the supply / discharge device 2 in the recess 28a of the receiving table 28 of each transport table 6 in the upstream portion of the straight traveling unit on the return path side.
[0020]
The operation of the supply device 13 of the supply unit 3a in this operation will be described below. The swivel lift 20 of the supply device 13 moves up and down in conjunction with the travel pitch of the transport table 6 and performs the operations of suction and suction release of the CD suction unit 18 of the slide hand 23.
[0021]
That is, each slide hand 23 is returned by the rodless cylinder 24 to the upstream side of the swivel lift 20 in the swivel direction. By descending in this state, the CD adsorber of the slide hand 23 facing the sub-table 11 side. A CD is adsorbed at 18 and the CD adsorbed by the CD adsorber 18 of the slide hand 23 facing the conveyance table 6 side is adsorbed by the CD adsorber 18 on the recess 28 a of the receiving table 28 of the conveyance table 6. The CD is released and stored in the recess 28a.
[0022]
At this time, the transport table 6 moves at a constant speed, the bracket 25 of the slide hand 23 comes into contact with the dog 26 provided on the transport table 6, and the slide hand 23 moves integrally with the transport table 6. The CD is stored in the recess 28a. When the slide hand 23 facing the transport table 6 moves along with the transport table 6 by a predetermined distance and the CD is supplied to the transport table 6 during this time, the swivel lift table 20 is raised. Thereafter, the swivel lift 20 is intermittently swung in the direction of the arrow (the travel direction of the endless chain 5), whereby the bracket 25 is detached from the dog 26 and the slide hand 23 is stopped. Returned to the position. The above-described operation is repeatedly performed when the slide hand 23 that has adsorbed the CD from the sub-table 11 in the previous operation faces the transport table 6 side by the turning of the turning lift 20.
[0023]
On the other hand, the operation of the discharge device 15 is basically the same as the operation of the supply device 13, but the operation of the CD adsorber 18 of the slide hand 23 is reversed and faces the receiving table 28 of the transport table 6. Adsorption is performed when the slide hand 23 is lowered, and the suction is released in a state where the slide hand 23 is swung and lowered on the sub-table 14. Also in the discharge device 15, the slide hand 23 facing the transport table 6 is interlocked with the transport table 6 for a predetermined distance in the suction state.
[0024]
The supply device 13 and the discharge device 15 are intermittently operated, and the supply device 13 and the discharge device are provided by providing intermittently rotating tables on the pre-supply process side and the post-discharge process side of the supply device 13. The pre-supply process device and the post-discharge process device for each of the 15 can be smoothly connected to the supply device 13 and the discharge device 15, respectively.
[0025]
【The invention's effect】
According to the present invention, it is possible to smoothly supply and discharge the flat plate member to and from the conveying table that moves in the linear direction according to the traveling of the chain member by intermittently turning and raising and lowering the turning elevator. Each of the supply device and the discharge device that constitutes the supply / discharge device includes a swivel lift that intermittently swivels and lifts, and a slide hand that is slidably provided on a slide base provided on the swivel lift. Thus, the supply / discharge device composed of both devices can be installed in a small space on the side of the transfer table moving device. In addition, it is possible to smoothly connect the pre-supply process apparatus and the post-discharge process apparatus to the supply / discharge apparatus.
