Next, the operation of the printing plate supply apparatus 1 will be described with reference to FIGS.
Description will be given according to the control flowchart shown in FIG.
First, in step S1 of FIG. 6, checking of each part and movement of the origin are performed as initial settings. For example, punch unit 5
The contact pins 55a, 55b, 55c, 55d of 0 are moved to the origin of the punch table 51 in the outward direction. In step S2, an operator's start instruction from the operation panel 14 or an automatic operation start instruction from another controller 13 is waited for. When the start instruction is issued, the process proceeds to step S3. In step S3, it is determined whether or not a printing plate supply command for taking out the printing plate from the predetermined pallet 23 and supplying it to the conveyor 3 has been issued. In step S4,
It is determined whether or not a printing plate supplement instruction has been issued. In step S5, it is determined whether or not another processing instruction has been issued.
If it is determined that no other processing command has been issued, step S
Return to 2.

When it is determined that the printing plate supply command is issued, the process proceeds from step S3 to step S6. Step S6
Then, a printing plate supply process (described later) is executed. If it is determined that the printing plate supplement instruction has been issued, steps S4 to S
Move to 7. In step S7, a printing plate supplement process (described later) is executed. If it is determined that another processing instruction has been issued, the process proceeds from step S5 to step S8. Step S
At 8, the other processing according to the command is executed.

In the printing plate supply process of step S6 of FIG. 6, in step S11 of FIG. 7, the pallet elevating part 34 is positioned 50 mm below the target pallet position by driving by a motor and a ball screw (not shown). That is, the pull-out rail pair 42 is located 50 mm below the target rail pair 22 on which the pallet 23 is mounted. In step S12, the engaging member 45 of the drawer means 43 provided in the pallet elevating part 34 is moved from the side opposite to the pallet side to the pallet side by an air cylinder (not shown). Due to this movement, the recess 46 formed in the engaging member 45 is arranged below the pin 26 standing on the target pallet 23. In step S13, the pallet elevating part 34 is raised by 50 mm. Due to this rise, the recess 46 of the engaging member 45 engages with the pin 26, and the rail pair 42 for pulling out and the rail pair 22 on which the target pallet 23 is placed are positioned on the same straight line. Step S
At 14, the fixing means 27 is operated to release the fixing of the pallet 23. In this embodiment, the fixing means 27 is a mechanism that opens and closes by a solenoid between a position where the roller 25 of the pallet 23 is locked and a position where the roller 25 is opened.

In step S15, the engaging member 45 is returned to the side opposite to the pallet. Therefore, the pallet 23 engaged with the engaging member 45 is pulled out from the rail pair 22 to the pull-out rail pair 4
2 is pulled out. At this time, the guide roller 47 guides the pallet 23 so that the pallet 23 can be smoothly pulled out onto the pull-out rail pair 42. When the sensor 48 confirms that the drawing of the pallet 23 is completed, the process proceeds to step S16. In step S16, the air cylinder 39 is moved to the front side of the apparatus in FIG. 2 by an appropriate driving unit according to the size of the printing plate. Since the printing plate is stored in the pallet 23 according to the size and the type of positive / negative, the printing plate size can be determined by selecting the pallet 23. In the subsequent step S17, the air cylinders 37 and 39 are operated to lower the front suction means 36 and the rear suction means 40 onto the printing plate in the pallet 23 that has been pulled out. In step S18, a vacuum pump (not shown) is operated to suck the printing plate by the front suction means 36 and the rear suction means 40. At this time, according to the size of the printing plate, the front suction means 36 and the rear suction means 4
Each of the suction areas 0 may be switched.

When the suction of the printing plate is confirmed by an appropriate vacuum switch or the like, the front suction means 36 is operated at step S19.
Raise. Then, in step S20, the rear suction means 40 is raised. The reason why the front side suction means 36 is raised before the rear side suction means 40 is to prevent the two printing plates from being picked up and to facilitate the separation. A publicly known peeling claw or a separating means by blowing air may be provided together to ensure the reliability.

In step S21, the engaging member 45 is returned to the pallet side and the pallet 23 is stored on the original rail pair 22. After the sensor 28 confirms that the pallet 23 has returned to the pallet storage portion 20, the pallet 23 is fixed again by the fixing means 27 in step S22.
In step S23, the pallet elevating part 34 is moved downward by 50.
After moving by mm, the engagement between the engagement member 45 and the pin 26 of the pallet 23 is released. After that, in step S24, the engaging member 45 is moved to the side opposite to the pallet side and returned to the original state. Step S
At 25, the pallet elevating unit 34 is lowered to lower the printing plate sucked and held by the printing plate transport unit 33. When the printing plate descends onto the punch section 50, the suction of the printing plate is released in step S26.

Next, the operation from punching the printing plate to conveying it to the conveyor will be described with reference to FIG. In the initial setting of step S1 in FIG. 6, each contact pin 55a, 55b, 55c, 55d of the punch section 50 is moved to the outside of the punch table. When the printing plate is supplied onto the punch table 51 in this state, step S
In 27, the hit pin 55a is moved by an amount corresponding to the biting amount of punching. Subsequently, in step S28, the hit pin 55a is moved to the punch block 53 side to insert the printing plate into the punch block 53, and the hit pin 5
5b and 55c are also moved toward each other to position the printing plate. In the present embodiment, these hit pins are controlled so as to move in advance according to the size of the printing plate.For example, it is possible to detect whether a predetermined pressure is applied to the hit pins by a micro switch or a pressure switch. The movement of the hit pin may be stopped, or the movement of the hit pin may be stopped by detecting the position of the printing plate end portion.

Contact pins 55a, 55b, 55c, 55
When the movement of d, is completed and the printing plate is detected by the sensor 57 for confirmation, the process proceeds to the next step S29. In step S29, the positioned printing plate is moved to the punch table 5
Then, in step S30, the punch block 53 is operated by a driving unit (not shown) to perform a predetermined punching process. In the punching process, the punch block 53 may be selectively operated depending on the type of the printing plate and the shape of the pin when the plate is attached to the plate-making machine or the printing machine in the subsequent step. In step S31, the suction of the printing plate is released, and then in step S32, the printing plate is punched by the block 53.
Eject more. That is, the hit pins 55a, 55b,
While returning 55c to the origin, move the hit pin 55d toward the center of the punch table 51 to move the punch block 53.
The printing plate inserted in is discharged from the punch block 53.

The punching operation in the punch section 50 is completed by the above operation. Subsequently, the printing plate is discharged from the punch unit 50 to the conveyor 3 by the operation from step S33. First, in step S33, the discharge carrier 64 of the discharge unit 60 is moved to the punch side along the guide pair 63 by an air cylinder (not shown). In step S34, the ejection portion suction means 66 is lowered to the punch side end portion of the printing plate by the air cylinder 65 provided in the ejection carrier 64. When the lowering is completed, the printing plate is sucked in step S35. The ejector suction means 66 may switch the suction area in accordance with the size of the printing plate, like the front suction means 36 and the rear suction means 40. When the suction is completed, the discharge portion suction means 66 is raised in step S36. In the following step S37, the discharge carrier 64 is returned to the conveyor 3 side. At this time, since the discharge portion suction means 66 holds only the punch side end portion of the printing plate, the non-punch side of the printing plate is moved by the movement of the discharge carrier 64. Usually, the back surface of the printing plate is not related to image formation, and therefore some scratches are allowed. In this embodiment, a guide guide 52 is provided on the punch block 53 in order to prevent the occurrence of scratches on the back surface of the printing plate and to facilitate transportation.

In step S38, the discharge portion suction means 66
Is lowered on the printing plate holding table 11 of the conveyor 3, and the punch holes machined by the punch section 50 are moved to the printing plate holding table 11
Engage the pin. In step S39, the suction by the discharge portion suction means 66 is released, and the discharge portion suction means 66 is raised to deliver the printing plate to the conveyor. In the printing plate replenishing process in step S7 of FIG. 6, when the operator issues an instruction to replenish the pallet 23 with an appropriate printing plate, first, the printing plate transport unit 33, which interferes with the replenishment, is retracted upward. Therefore, in step S41 of FIG. 9, the pallet elevating part 34 is moved to the uppermost part. At this time, the printing plate transport unit 33 on the pallet elevating unit 34 also moves to the uppermost position.
In the following step S42, the printing plate transport section 33 is locked by the locking means 70. That is, the locking means 70 raises the engaging member 71 by rotating the engaging member 71 inside the main body frame by a predetermined angle by the rotary air cylinder 72. Will support. As a result, even if the pallet elevating unit 34 descends, the printing plate transport unit 33 can be retained at the uppermost position. Hereinafter, from step S43 to step S
Since the processing up to 47 is the same as the processing from step S11 to step S15 of the printing plate supply processing shown in FIG. 7, the description thereof is omitted here. When the pulling out of the pallet 23 is completed in step S47, step S48
Then, the pallet elevating part 34 is lowered to the refill position while holding the pallet 23. This replenishment position is, for example, as shown in FIG. 10, a height where the operator can easily replenish the pallet with printing plates.

Here, the pallet elevating part 3 for pulling out the pallet 23 and for holding the pallet 23 and elevating the pallet 23.
4 is provided, the vertical mechanism for pulling out the pallet 23 can also be used for the vertical movement of the pallet 23 itself. Therefore, the printing plate can be replenished with a simpler structure than the conventional one. When the pallet 23 is lowered to the replenishment position in step S48, the operator replenishes the pallet 23 with the printing plate. In step S49, the operator waits for input of a replenishment completion command. When the replenishment completion command is input, the pallet 23 is stored again. That is, step S50
After the pallet elevating part 34 is raised to the original pallet storage position in step S51, steps S51 to S54 are performed, but this operation is also the same as steps S21 to S24 in FIG.

Next, from step S55, the printing plate transport unit 3 is started.
Perform the return operation of 3. That is, in step S55, the pallet elevating part 34 is raised to the uppermost part, and the printing plate conveying part 33 is placed on it again. In step S56, the rotary air cylinder 72 is operated to release the lock. Then, in step S57, the pallet raising / lowering section 34 is returned to the origin while the printing plate conveying section 33 is placed.

[0033]

In the printing plate supply device according to the present invention, space is saved because the pallets supported so as to be drawn out are stacked. Further, since the vertical movement mechanism necessary for pulling out these pallets is used so that the pulled-out pallets themselves can also be moved up and down, even if the pallets are high and stacked, the printing plates can be replenished at a low position.
