Abstract

PROBLEM TO BE SOLVED: To provide an inexpensive and simple carrying apparatus wherein printing unit changing trucks are successively pushed out to a preparation area side without adding any special device such as transferring device. SOLUTION: A pin 12 for carrying is fixed on the back side of the bottom face of a printing unit changing truck 10 in a gravure printing machine and a carrying apparatus for carrying this truck 10 between the side of the printing machine and a preparation area consists of a chain conveyer 20 installed below the floor between the side of the printing machine and the preparation area and hooks 21 for hooking a pin 12 for carrying the truck 10 fixed on the chain conveyer 20. The truck 10 can be carried from the side of the printing machine to the preparation area only by hooking the hook 21 to the pin 12 for carrying and driving the chain conveyer 20.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gravure printing machine having a plurality of printing units.

[0002]

Conventionally, in a gravure printing machine, parts (mainly plate cylinders, doctors, applicators, pumps, ink tanks, etc.) to be replaced in each printing unit are switched by a cart (usually a trolley, a carriage). (Called "etc.") is made into a cassette, and a system for performing preparatory work by external setup is used. These printing unit replacement carts are moved and set from the operating side (man side) of the printing machine so as to pass through the frame portion of the printing unit at right angles to the web direction, and when the operating unit temporarily moves between the units. In some cases, it may be moved in parallel with the web direction and set.

The external setup preparation work using the dolly as described above may be carried out by the side of the printing machine, but in general, it is often carried out collectively after being manually carried to the preparation area. In any case, the transportation of these items was a heavy work due to the extremely heavy trolley, which caused the switching work to be prolonged. To reduce this heavy labor, it is possible to use some automated equipment to transport the trolley, but since there are usually multiple printing units, the trolley that has already been transported will have a different location for the next trolley. Need to be evacuated, and if an attempt is made to automate this evacuation, the transport system becomes redundant and expensive.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is that a dolly is sequentially pushed to the preparation area side without adding a special device such as a transfer device. It is to provide an inexpensive and simple transport device.

[0005]

In order to achieve the above object, the present invention has a carrying pin attached to the back side of the bottom surface of a printing unit exchange carriage in a gravure printing machine,
A conveyor device for transferring this carriage between the printing machine side and the preparation area, a chain conveyor installed under the floor across the printing machine side and the preparation area, and the chain conveyor attached to the chain conveyor. It is characterized by comprising a hook for hooking the carrier pin of the carriage.

[0006]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic plan view showing a printing machine room P and a preparation area A separated by a slide door D. A gravure printing machine (not shown) is installed in the printing machine room P, and since the ink is solvent-based, it has explosion-proof specifications.
The printing unit exchange cart 10 shown in the figure is taken out from the printing unit section of the gravure printing machine when printing is completed, and is installed in the groove of the floor across the printing machine side and the preparation area A. It is set on the hook 21 of. When all the carriages 10 are set, the gear 22 is driven and the chain conveyor 20 rotates, so that the carriages 10 are conveyed. That is, the transport pin 12 is attached to the bottom side of the bottom of the carriage 10 together with the wheels 11, and the hook 21 attached to the chain conveyor 20 hooks the transport pin 12 to move the carriage 10 from the printing machine room P to the preparation area. Transport to A. When the carriage 10 enters the preparation area A, the hook 21 sequentially pushes the carriage 10 to the preparation area A.

FIG. 2 is a schematic perspective view showing how the hook 21 hooks the carrying pin 12 of the carriage 10 to carry it, and FIG. 3 is a sectional view of the same. As shown in FIG. 2, the hook 21 has a notch on one side, and the transport pin 12 of the carriage 10 is inserted from the notch side and hooked. Two transfer pins 12 are provided on the back side of the bottom surface of the trolley 10, and correspondingly, two hooks 21 are provided for each trolley 10, so that the trolley 10 can travel stably. It is like this.

FIG. 4 is a schematic side view showing how the hook pushes the trolley to the preparation area. As shown in FIG. 1, the vicinity of the entrance of the preparation area A is the end point of the chain conveyor 20, and the hook 21 is provided as shown in FIGS.
When it reaches the end point, it wraps around under the chain conveyor 20. When the hook 21 wraps around the lower side of the chain conveyor 20, the transport pin 12 is disengaged from the hook 21, so that the carriage 10 is sequentially pushed out to the preparation area.

FIG. 5 illustrates a modification of the hook. In the modified example of FIG. 5B, the play portion of the transport pin is shaped so as to have a narrow play. Therefore, even if the chain conveyor 20 stops and inertia acts, the range in which the carriage 10 moves is narrow, and the impact can be suppressed low. At that time, since the wheels of the carriage 10 are parallel to the chain conveyor 20, the transport pin 12 of the carriage 10 does not come off the hook 21.

[0011]

As described above, the transporting device for the carriage for exchanging the printing unit according to the present invention hooks the transporting pin of the truck on the chain conveyor installed under the floor between the side of the printing machine and the preparation area. By attaching the hook, the carriage for exchanging the printing unit after printing is conveyed from the side of the printing machine to the preparation area, and then the carriage can be sequentially pushed out to the preparation area without using a special device such as a transfer device.
