DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0008]
FIG. 1 is a schematic plan view showing a printing press room P and a preparation room A separated by a slide door D. FIG. In the printing press room P, a gravure printing machine having a plurality of printing units U is installed. Since the ink to be used is solvent-based, the printing press room P is an explosion-proof area.
[0009]
FIG. 2 is a perspective view showing a conveyance state of the printing unit exchange carriage. The printing unit exchange carriage 10 has directional wheels 11 at four locations, and can be moved in any direction by being pushed. The printing unit exchanging carriage 10 is conveyed by a conveying apparatus 20 having a U-shaped enclosure frame 21 as a main part as viewed from above for enclosing it. The conveying device 20 is provided with two wheels 22 on both sides of the enclosing frame 21, thereby moving on the tracks of the two rails 1. At both ends of the U-shape of the enclosure frame 21, an arm 23 that rotates between an inward position that holds the exchange carriage 10 and an open upward position is attached. Corresponding to the holding position of the arm 23, the replacement carriage 10 is provided with a contact plate 12. Since the transport device 20 having the above configuration transports the exchange cart 10 with the wheels 11 by pushing it, the transport device 20 can be transported with only a small output power (motor 24), and thus the entire device can be downsized. The transport device 20 has an explosion-proof specification because it moves in the printing press room P, which is an explosion-proof area, and electricity is supplied from a power supply cable 3 that slides on the upper suspension rail 2.
[0010]
At the entrance of the printing press room P, a transfer device 30 of the printing unit exchange carriage 10 is installed. This transfer device 30 is a bi-directional slide fork mechanism, and transfers the prepared replacement cart 10 from the preparation chamber A to the transport device 20, and the post-printing replacement cart 10 from the transport device 20 to the preparation chamber A. . When the exchange cart 10 is transferred with the fork of the transfer device 30, the main body of the exchange cart 10 has no space for passing the fork, so it is necessary to pass the fork between the bottom and the floor of the exchange cart 10, and the transport device 20. Since the fork of the transfer device 30 passes over the surrounding frame 21 and scoops the lower part of the exchange cart 10, the transport device 20 does not interfere with the fork of the transfer device 30 (the exchange cart). The height from the floor of the bottom of the floor is 10) or less.
[0011]
The procedure for preparing the printing unit exchange carriage 10 that has been prepared in the preparation room A beside the gap between the printing units U is as follows. First, the exchange cart 10 transported from the preparation chamber A is transferred to the transport device 20 by the transfer device 30 at the entrance of the printing press chamber P. Here, the transfer means that the exchange cart 10 is placed in the U-shaped enclosure frame 21. After the transfer, the exchange carriage 10 is transported by the transport device 20 to the preparation position beside the printing unit U. When reaching the preparation position, the conveying device 20 is stopped, and after the stop, the arm 23 holding the exchange carriage 10 is vertically lifted to release the hold of the exchange carriage 10. When the arm 23 is lifted vertically, the transfer device 20 returns to the transfer device 30 (in the direction of the arrow in FIG. 3) leaving the exchange carriage 10 as shown in FIG. The above procedure is repeated for the necessary number of the exchange carts 10 in order from the back, that is, the printing unit U far from the preparation chamber A with respect to the home position of the transport device 20 (side of the transfer device).
[0012]
The procedure for collecting the used printing unit replacement carriage 10 placed next to the printing unit U after the printing is completed in the preparation room A is as follows. First, the transport device 20 moves to the exchange cart 10 placed at a predetermined position on the rail 1 beside the printing unit U with the arm 23 vertically raised. Next, when the exchange cart 10 is completely taken into the enclosure frame 21 of the transport device 20, the arm 23 is closed and the exchange cart 10 is held. If it hold | maintains, the conveying apparatus 20 will move in the state which hold | maintained the exchange trolley | bogie 10 toward the transfer apparatus 30. FIG. When the transfer device 20 arrives next to the transfer device 30, the transfer cart 10 is transferred to another transfer device in the preparation chamber A by the transfer device 30. On the other hand, the transfer device 20 collects the remaining used exchange carts 10 in order from the home position of the remaining exchange carts 10, that is, the exchange carts 10 closer to the preparation room A.
[0013]
Further, in the present embodiment, in order to allow the printing unit replacement carriage 10 to be pulled into the printing unit U with high accuracy, the guide rail 4 for pulling in the replacement carriage 10 is devised as shown in FIG. Has been given. That is, the planar shape of the entrance portion I of the guide rail 4 is Y-shaped as shown in the figure, and even if the exchange carriage 10 stops with a slight deviation from a predetermined position, the wheels 11 of the exchange carriage 10 are not connected to the guide rail 4. Made it easier to get into orbit. Further, as shown in FIG. 5, the direction of the wheels 11 can be easily corrected as shown in FIG. 6 when the exchange carriage 10 is retracted by giving the Y-shaped inlet portion I a gentle downward slope. did.
[0015]
【The invention's effect】
As is clear from the above description, the switching operation after the end of printing can be easily performed by using the transport device of the present invention. And since the conveyance apparatus of this invention conveys in the form which presses the printing unit exchange trolley with a wheel, since conveyance is possible with a small output power, the whole apparatus can be reduced in size. In addition, the fork of the transfer device for transferring the printing unit exchange carriage from the preparation chamber to the transfer device and from the transfer device to the preparation chamber can pass over the U-shaped enclosure frame which is the main part. As a result, the apparatus can be made compact.
