In the fifteenth aspect of the present invention, since the carriage is advanced from the side to the lower side of the plate mounting position of the printing unit, the spaces on the upstream side and the downstream side of the printing material feeding direction in the printing unit can be effectively used. In addition, since the pan-pan positioning means and the transport cart positioning means make the pan-pan easy to be mounted on the printing unit by simply entering the transport trolley below the plate-mounting position of the printing unit, the operator moves the transport cart to the pan of the printing unit. After entering below the mounting position, there is no need to check the position of the panto with respect to the pantry mounting position by moving upstream and downstream of the printing material feeding direction of the printing unit.

According to a sixteenth aspect of the present invention, when the slide frame is slid in the transport cart entry direction with respect to the main frame, the plate boom can be mounted on the printing unit in a state where the transport cart enters below the boom mounting position. If the slide is retracted in the transport trolley retraction direction, the overall length of the transport trolley becomes shorter and more compact, so that the direction can be changed freely in a narrow place when conveying the pan out by the transport trolley, which simplifies the operation of the transport trolley. .

According to the seventeenth aspect of the present invention, the positioning plate can be easily moved to the display corresponding to the ends of the various pans by the slide operation of the sliders, and the preparation time for replacing the pans can be shortened.

In the eighteenth aspect of the present invention, even when the plate is inadvertently contacted with the positioning plate when the plate is loaded on the carriage, the positioning plate rotates downward in response to the bias force of the plate biasing member. The failure of the positioning plate can be prevented when the plate is in contact with the determining plate from above.

In the nineteenth aspect of the present invention, when the carriage cart enters from below the plate mounting position, the carriage bogie positioning means and the unit fixing side engage with each other by a coupling operation, whereby the carriage trolley can be firmly fixed to the unit fixing side.

In the twentieth aspect of the present invention, when the transport cart enters the printing unit, the hook is automatically engaged to the member to be engaged and the transport cart is fixed to the unit fixing side, so that the worker carries the transport cart separately from the operation of entering the transport cart into the printing unit. No troublesome work is required, such as fixing the trolley to the printing unit, and the transport trolley can simply be fixed to the unit fixing side.

While advancing to the end, the key 32b is inserted into the key groove 31b and the plate cylinder 31 is rotatably supported by the both side frames 2a. As shown in FIG. 2), the first driving unit 42 is controlled and the lifting unit 40 is lowered.

17 to 19, the control panel 7 controls and rotates the rotation drive unit 32c in a state in which the plate cylinder 31 is rotatably supported by the side frames 2a. Only the rotation angle θ ₃ is rotated by the downstream side plate 31 relative to the upstream side plate 31 of the printing unit 2.

Here, in FIG. 17 to FIG. 19, the pressure 37 shows the state in which the printed material W is pressed against the plate 31 from the upper side side plate 31 of the adjacent printing unit 2. When rotating the downstream side plate 31 only relative to the rotation angle θ ₃ , the pressure plate 37 is slid upward by a slide mechanism (not shown), and the pressure plate 37 is printed onto the plate plate 31. It is performed in the state which does not press the ash W from upper direction.

Next, a method of mounting the plate 31 on each printing unit 2 of the printing apparatus 1 will be described.

First, the operator H slides the positioning plate 57a to a position corresponding to the plate 31 to be replaced next to the display member 57i while the printing apparatus 1 is operating. The plate plate 31 is loaded on the plate plate rotating part 50 while the positioning plate 57a is brought into contact with the axial center end of the plate plate 31.

Next, as shown in Fig. 16 (a), the plate rotator 31 is rotated by the plate rotator 50 so that the tip of the protrusion 56d is in contact with the register mark 31c by tilting the bar 56c. In the state where the projection 56d is in contact with the register mark 31c, the brake lever 55a is operated to stop the rotation of the plate cylinder 31.

As described above, the transport trolley 5 on which the plate 31 is loaded is waited for each printing unit 2.

When the printing operation of the printing apparatus 1 is finished, the used plated copper 31 is separated from each printing unit 2 of the printing apparatus 1, and then the rotation driving unit 32c is driven to advance the key. The plate cylinder 31 is rotated so that the 32b is located at the upper end of the support shaft 32a.

Thereafter, as shown in FIG. 11, each of the transport trolleys 5 held for each of the printing units 2 enters below the plate mounting position of each of the printing units 2. When the carriage trolley 5 enters below the plate mounting position of the printing unit 2, the carriage trolleys 5 have projecting cross sections of both guide members 52a on both sides of the base frame 41. Since it is brought into the lower portion of the printing unit 2 while sliding contact, the position in the width direction of the transport cart 5 with respect to the printing unit (2) is determined.

Then, in the state of FIG. 11, if the transport cart 5 is further moved into the printing unit 2, as shown in FIG. 9, the striker 52d presses the hook 48c, and this hook 48c is carried out. It rotates in response to the biasing force of this coil spring Sp. Then, when the carriage cart 5 is further entered into the printing unit 2, the striker 52d corresponds to the coupling groove 48d, and the hook 48c is applied to the restoring force of the coil spring Sp. And a striker 52d is coupled to the coupling groove 48d, and the longitudinal position of the transport cart 5 with respect to the printing unit 2 is determined.

Therefore, when the transport cart 5 enters from below the plate mounting position of the printing unit 2, the transport cart positioning means 13 and the hook 48c are coupled by mutually engaging operation, and the transport cart 5 ) Can be firmly fixed to the unit fixing side of the printing unit 2.

Thereafter, as shown in Fig. 16C, the first driving unit 42 is driven and the lifting unit 40 is further raised to stop the printing unit 2 at a position in the middle of the vertical direction. As shown in Fig. 16 (d), the second drive unit 47 is driven, the plate cylinder 31 is rotated around the axial center, and the key groove of the plate cylinder 31 is driven by the non-contact sensor 6. (31b) The position data θ _b is detected.

And the position data (theta) _b of the key groove 31b detected by the said key groove position detection mechanism 60 by the said calculation part 7b, and the position of the register mark 31c memorize | stored in the said storage part 7a. Based on the data θ _a , the angles θ ₁ and θ ₂ around the axial center between the key groove 31b and the register mark 31c are respectively calculated.

In addition, in the upstream side plate 31 and the downstream side plate 31 of the adjoining printing unit 2, the calculation unit 7b of the downstream side plate 31 with respect to the upstream side plate 31 is used. Equation (1) which shows the rotation angle (θ ₃ ) for measurement

(1) θ ₃ = 2 (n + 1) π + θ ₁ -θ ₂ -L / r + θ _α (n is an integer)

Is expanded and extended to both end portions of the support shaft 32a in the axial direction of the plate 31. As shown in FIG. Then, while the key 32b is inserted into the key groove 31b, the plate cylinder 31 is rotatably supported by both side frames 2a.

As shown in Fig. 16G, the first driving unit 42 is driven to lower the lifting unit 40. Then, as shown in Figs. 17 to 19, the rotation driving unit 32c is moved. Drive and rotate the downstream side plate 31 only with the rotation angle θ ₃ relative to the upstream side plate 31 of the adjacent printing unit 2 to mount the plate plate 31 to the printing unit 2. Quit.

Therefore, the position data θ _a of the register mark 31c necessary for knowing the position of the register mark 31c with respect to the keyway 31b is obtained in advance in the state in which the plate 31 is loaded on the carriage cart 5. Therefore, the time taken to obtain the angles θ ₁ and θ ₂ around the center of the shaft between the register mark 31c and the keyway 31b is shortened after bringing the transport cart 5 into each printing unit 2. do. The position data (θ _b) of the printing drum 31 for each printing unit (2) both the location of the key groove (31b) prior to mounting on the side frame (2a) of data (θ _b) detected, and the key groove (31b) of And the rotation angle θ ₃ for carrying out weighing of the downstream side plate 31 with respect to the upstream side plate 31 of the adjacent printing unit 2 by the position data θ _a of the register mark 31c. As can be seen, immediately after mounting the plate (31) on both side frames (2a) of each printing unit 2, the scale of each plate (31) is automatically made. Therefore, the stop time of the printing apparatus 1 at the time of replacement of the plate | board 31 becomes short, and work efficiency improves.

Next, a method of separating the plate 31 from each printing unit 2 of the printing apparatus 1 will be described.

First, in a state in which the pans 31 are supported on each of the support shafts 32a, and the carriage trolley 5 without the pans 31 is carried under the printing unit 2, The first driving unit 42 is driven to raise the elevating unit 40 to an elevated end position, and the elevating unit 40 supports the plate 31.

Thereafter, in the step of guiding the plate ridge from the transport cart to the unit fixing side of the printing unit by the plate guiding means, the key groove position of the plate is detected, and further, the control means makes the dimensional data of the plate circumference. And based on the mark position data of the platen carried on the transport trolley, calculating the angle of the axial center around the keyway position of the platen and the mark,
Thereafter, the plate guiding means rotates the plate rim so that the key groove corresponds to the key on the unit fixing side of the printing unit, and also inserts the key into the key groove to position the plate rim and the plate rim. And a rotatable support method of the printing apparatus, characterized in that it is rotatably supported on the unit fixing side of each printing unit. 23. The method of claim 21,
The mark formed in the said plate is a reference mark,
The board is loaded on the transport trolley so that the reference mark is in a predetermined position, and the transport trolley is waited for each of a plurality of printing units.
The distance between the transfer positions (L) of the two printing units of the printing units to the printed material among the printing units, the radius (r) of the plate cylinder, and the reference mark position data of the plate cylinder loaded on the transport cart by the control means On the basis of the calculation, the angles (θ ₁ , θ ₂ ) around the center of the shaft between the key groove position and the reference mark in the upstream and downstream of the two printing units of each of the printing units are respectively calculated. The rotation angle (θ ₃ ) for estimating the downstream side cylinder with respect to the side cylinder is expressed by the following equation (1)
(1) θ ₃ = 2 (n + 1) π + θ ₁ -θ ₂ -L / r (n is an integer)
And calculate
And the rotating plate is rotatably supported on the unit fixing side of each printing unit, and then the downstream plate is rotated by only the rotation angle θ ₃ with respect to the upstream plate. . 23. The method of claim 21,
The mark formed in the plate is formed at a position increased or decreased by a predetermined angle with respect to a normal reference position for fitting a printed pattern from an upstream side plate ridge of the printing unit arranged in parallel to a downstream side plate plate. Is a quasi-mark
The board is placed on the transport trolley so that the provisional mark is in a predetermined position, and the transport trolley is waited for each of the plurality of printing units.
Distance between the transfer positions (L) of the printing units of the two printing units of the printing units to the printed material by the control means, the radius (r) of the plate cylinder, the provisional mark position data of the plate cylinder loaded on the transport cart, and On the basis of the reference position correction angle θ _α for correcting the downstream side plate to the normal reference position for fitting the printed pattern, the upstream side plate and the downstream side of the two printing units of each printing unit. The angle of rotation (θ ₁ , θ ₂ ) around the axial center between the keyway position in the plate and the provisional reference mark is calculated, respectively, and the angle of rotation (θ) for estimating the downstream plate cylinder with respect to the upstream plate cylinder. ₃ ) by the following formula (1)
(1) θ ₃ = 2 (n + 1) π + θ ₁ -θ ₂ -L / r + θ _α (n is an integer)
And calculate
And the rotating plate is rotatably supported on the unit fixing side of each printing unit, and then the downstream plate is rotated by only the rotation angle θ ₃ with respect to the upstream plate. .
