As shown in FIGS. 3 and 7, the printing table 2 has a mounting surface for the card 100 to be printed on its upper surface, and a space 2a formed inside the printing table 2. Many small holes are formed towards the surface. Also, an air suction hose 17 connected to the printing table 2 communicates with the space 2a.
The other end of the air suction hose 17 is connected to the fixed shaft 15 via a rotary joint 19, and is connected to a vacuum device (not shown) through a passage 15a formed in the fixed shaft 15, whereby the card 100 A suction means is configured.

This rotary joint 19 is connected to the holding arm 3 by a connecting member 16, and is configured to rotate together with the holding arm 13 around the fixed shaft 15.

Further, around the space 2a, a card positioning pin 22 is arranged so as to be able to protrude and retract through a hole passing through the upper part in one direction, and a downward force is applied to the positioning pin 22 by a spring. In the Tsutomu state, it is immersed from the top surface of the printing table 2. As shown in FIG. 12, the positioning pins 22 include a plurality of pins (six in this embodiment) arranged around the card 100 placed on the printing table 2.
It is composed of a and 22b. In FIG. 12, there is J'3, 22a is a positioning pin that protrudes onto the printing table 2 before the card 100 is placed, and 22b is the card 100/'.
This is a positioning pin that is made to protrude from the hole that has been cut out.

FIG. 11 (A>(B)) shows another example of the card positioning pin, in which the positioning pin 22 passes through the hole 90 of the printing table 2 by ξ1.
A pin 92 rotatable around a shaft 91 is attached to the tip of G, and a clockwise rotational force is applied by a spring 93. Then, when the positioning pin 22c is turned upward from the retracted state shown in FIG. 11(A), the pin 92 rises while rotating counterclockwise, as shown in FIG. You will be pushed from the other side. If this structure is used in place of the positioning pin 22b, when the card 100 is fed onto the printing table 2, even if the position of the card 100 is shifted and its side is located on the hole 90, the pin 92 This has the advantage that the card 100 can be positioned more smoothly.

The actuating member 4 does not rotate relative to the holding part 3a,
It is fitted in such a way that it can move only in the axial direction, and as shown in FIGS. 3 and 7, push-up pins 42 are attached around the upper end of the pin 42, respectively, facing the respective positioning pins 22, and as shown in FIGS. A cam follower 44 is attached to the side. Further, a rib 47 is attached to the upper side thereof, and a spring 43 is opened and opened between the rib 47 and the holding portion 3a to apply a force in the direction () to the holding member 4.

The cam follower 44 is crimped onto the cam 18 which is supported by a support member 20 that is connected to the frame 12 of the device. As shown in FIG. 7, this cam 18 is formed only in a part of the circumferential direction (the A circumference and the B station).

Is there a printed t on the inside of the guide rail 9? Positioning member 2
3 is attached, and this positioning member 23 is formed with a through hole 23a through which the printing table passes, and the printing table 2 rises from the state on the left side of FIG. The dimension of the Q passer 23a is formed to be slightly larger than the outer circumferential dimension of the printing table 2 so that the flange ffIJ2b contacts the lower surface of the positioning member 23 through the hole 23a.

8 to 10 show the supply means +15 and ejection means for the card 100, and a bracket 34 is attached to the upper part of the fixed shaft 15.
A roller holding arm 33 is attached to the distal end of the bracket 34 via a horizontal shaft 33a so as to be rotatable around this @33a. This roller holding arm 33
A card feed roller 31 is attached to the tip of the card.
On the other hand, a weight 35 is attached to the base end of the holding arm 33 to adjust the pressing force of the roller 31 against the printing table 2. The card 10 is placed on the surface of this roller 31.
In order to exhibit good frictional force against zero, the card is covered with rubber or sponge, and is configured to be rotated by a motor 32 to pull the card 100 supplied onto the printing table 2 to a predetermined position.

Further, a cylinder 24 is attached to the bracket 34 facing the base end of the holding arm 33, and by pressing down the base end of the holding arm 33 and rotating the holding arm 33 around 4433a, the roller 31 is moved back from the printing table 2.

At a position adjacent to the printing table 2, there is a magazine 26 for stacking and storing cards 100 to be stamped, and a loading R1.
A predetermined amount of cards 100 are stacked in the magazine 26 and the peripheral edge thereof is supported by a guide rod 27. The loading device 39 is configured such that the bushing blade 29 is moved forward and backward by a piston rod 37 of a cylinder 36 via a bracket 38.

It touches the other two sides of 0.

Further, a holding arm 85 is attached to the fixed shaft 15, and a guide groove 81 is formed on the opposing inner surfaces of the holding arm 85, and a leaf spring 82 that allows movement in only one direction is formed in the guide groove 81. is provided. A cylinder 83 is attached to the base end of the holding arm 85, a cam member 84 is attached to the tip of the piston rod, and a spatula plate 80 that projects downward is attached to the cam member 84. At the same time, both ends of the cam member 84 fit into the guide groove 81.
has been incorporated into.

Then, when the cylinder 83 is extended from the state shown in FIG.
The cam member 84 moves along the guide 17i81, passes the leaf spring 82, is guided by the leaf spring 82 by the contraction of the cylinder 83, passes above the guide groove 81, and descends after reaching the left end. Return to original position. With this operation, the tip of the spatula plate 80 pushes the card 100 on the printing table 2 and moves to the position shown by the imaginary line, thereby causing the card 1
Send 00 into chute 86 and card 10 from here.
0 is discharged onto a belt conveyor 87.

Next, the operation of this device will be explained. First, in the indexing table device 1, at the A station where the card 100 is supplied, the printing table 2 is in a lowered position supported by the cam 64, and the cam follower 44 is located on the cam 18, as shown in FIG. The actuating member 4 is then in an intermediate position. In this state, the push-up pins 42 of the printing member 4 project only the positioning pins 22a shown in FIGS. 8 and 13 onto the printing table 2.

In this state, the card 100 is fed onto the printing table 2 of the Δ station by the card feeding device. This operation will be explained with reference to FIGS. 8 and 10.
The button blade 29 is moved to the left by the first movement, and the card 100 at the lowest position in the magazine 26 is pushed out onto the printing table 20.

At this time, positioning pins 22a protrude above the printing table 2, and by pressing the card 100 fed onto the printing table 2 against the positioning pins 22a with the roller 31, the card 100 is set at a predetermined position.

Next, the holding arm 3 is rotated around the fixed lN 115 by the driving device 11, and the printing table 2 is moved to the position shown in FIGS. 1 and 8.
Move to station. At this time, the rotary joint 19 connected to the holding arm 3 by the connecting member 16 also rotates at the same time (see FIG. 3).

As a result, as shown in FIG. 7, the cam follower 45 of the shaft 40 rolls on the cam 64, causing the printing table 2 to move horizontally a. The positioning pins 22b also protrude above the printing table 2, and the card 100 is surrounded and positioned together with the positioning pins 22a.

Further, a suction device (not shown) reduces the pressure in the space 2a of the printing table 2 through the passage 15a1 and the vacuum hose 17, thereby adsorbing and fixing the card 100 on the printing table 2 onto the printing table 2. During this operation, the card 100 is supplied onto the subsequent printing table 2 at the A station by the same operation as described above.

Further, the printing table 2 is rotated to the C station controller, and the card 100 is placed on the printing table 2 of the subsequent A station.
While moving from station B to station C, cam follower 44 comes off from cam 18, so
The moving member 4 is lowered by the force of the spring 43, so that the push-up pin 42 is lowered and the positioning pins 22a and 22b are lowered.
is inserted from above the printing table 2.

Then, as the holding arm 3 continues to rotate further, as shown in FIG. 7, the cam follower 45 rolls on the inclined surface of the cam 61, causing the marking IE table 2 to turn upward and reach the D station. In this state, the printing table 2C is positioned close to the lower side of the positioning member 23 so as to extend to the left side in FIG. Subsequently, the cam 61 is pushed up by the operation of the cylinder 6, and the printing table 2 is fitted into the positioning member 23 as shown on the right side of FIG. In this state, there is a slight gap between the printing table 2 and the positioning member 23, and since the printing table 2 has room to move in the horizontal direction, the printing table 2 is moved diagonally by the clamp pin 63 shown in FIG. Press it from the side to press it against the wall surface of the through hole 23a of the positioning member 23 and fix it.

Further, as shown in FIGS. 3 and 6, by operation #J of the cylinder 7, the pattern 71 is inserted from the side under the cam 61 to support the cam 61 via the row 562. This is to prevent the printing table 2 from moving downward when printing pressure is applied to the printing table 2 at m-.

In this way, by moving the carriage 5 along the guide rail 9 while completely preventing the horizontal and vertical movement of the printing table 2, printing is performed on the card 100 on the printing table 2 of the D station. Do the following. This printing is performed by a blanket 51, and this blanket 51
printing plates 5a and 5b on which ink of a predetermined color is placed;
As it passes over, the ink is transferred (see FIGS. 1 and 2) and printed onto the card 100 at the D station.

After the above printing is completed, the clamp pin 63 is moved back to release the horizontal fixation to the printing table 2, and the cylinder 7
By the operation of the cylinder 6, the cam 61 is moved back from the bottom side of the cam 61, and the printing table 2 is moved downward from the positioning member 23, and then the holding arm 3 is rotated. Therefore, avoid moving from D station to E station.

Then, it reaches the J station after passing through the FSG, H, and 1 stations, but when moving from the L station to the J station, the printing table 2 is rotated by the cam 61, as in the case of reaching the D station. The printing table 2 is further raised by the cylinder 6 and fitted into the positioning member 23 from below. After fixation in one horizontal direction by the clamp pin 63 and fixation in the vertical direction by the wedge 71, printing is performed by the holder of the carriage 5 in the same manner as described above. In this printing, the printing plate 5a is used.

The ink i of a different color from the ink of 5b is the printing plate 5c.

5d, printing is performed by the blanket 51.

Then, upon reaching the L station via the K station, the J node 100 printed by the publishing device shown in FIGS. 8 and 9 is ejected. That is, at the printing station, the vacuum hose 17 communicates with the popular passage 15b via the rotary joint 19, so that the printing table 2
Air is sent into the inner space 2a to release the card 100 from being adsorbed, and the card 100 is pushed by the spatula plate 80 by the operation of the cylinder 83, pushed out to the shooter 86, and discharged by the belt conveyor 87.

The printing table 2 then moves to the A station, and the cycle from supplying the card 100 is repeated in the same manner.

As described above, while the printing table 2 rotates once by the holding arm 3, the △ station controller supplies the card 100, the D station and the J station print in different colors, and the printed card 100 is ejected from the station. In this embodiment, this operation is sequentially performed in the same manner in each of the 12 printing machines located at A-L.

The card 100 is fed onto the printing table 2 by accurately positioning it using the positioning pins 22a and 22b, and during printing, the printing table 2 is completely fixed by the crank pin 63 and the pattern 71. Since the printing is performed in a state in which the colors are aligned, there is no misalignment between the colors, resulting in precise printing.

In the above embodiment, an example was shown in which the pair of printing means were arranged so as to be located on the circular locus of the printing table, but three or more m1 means may be arranged. Further, the number of printing tables 2 is not limited to 12, and can be set arbitrarily.

(Effects of the Invention) As explained above, the present invention moves a plurality of card printing tables arranged along a circular trajectory at intervals between customers, and sequentially prints cards using a plurality of printing means. Since it uses two-dimensional printing, it is possible to precisely print multiple colors without causing any misalignment.
