Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a washing machine used to wash ink fountains installed in various printing machines.

[Conventional technology]

Traditionally, ink bottles for printing presses were washed by hand, as there was no washing machine, by filling a bucket or other container with cleaning solution and dipping the ink bottle removed from the printing machine into the solution. .

[The problem that the idea aims to solve]

As mentioned above, the conventional cleaning method was to wash by hand, so using a cleaning liquid such as gasoline or other volatile oil is inconvenient for the health of the worker, and it is also unreasonable to have to re-wash because the cleaning cannot be done sufficiently. This is a method that consumes a lot of cleaning fluid.

[Means to solve the problem]

This idea was developed to solve the above problem.
A cleaning liquid circulation system in which an object A to be washed, such as an ink fountain with ink or the like adhered to it, is supported on a support part ₃₁ of a support shaft 3 which is rotated by a drive device 6 in a container 1. In the case where cleaning is performed using a nozzle 7 that sprays cleaning liquid, the support shaft 3 is provided so that both left and right end portions thereof protrude outside the container body ₁₂ of the container 1, and the support shaft 3 is attached to the container body. 1 ₂ , and the bearing shaft 3 has one end supported by a bearing 4, and a slider 5 ₁ provided at the other end on the opposite side. 1 ₂ is characterized in that it has a moving device 5 that engages with a moving bearing 5 ₂ provided at 1 2 .

[Effect]

To wash the ink fountain A for the next printing after finishing printing, with the lid 2 open, move the ink fountain A to the support part 3 ₁ of the support shaft 3 in the container 1 _. At the same time, the support part 3 ₁ is fixed by the fixing body 3 ₁₂ .
Next, the cleaning liquid reservoir ₁₃ of the container body ₁₂ is filled with the cleaning liquid, and the opening ₁₁ is closed with the lid 2.
When the cleaning liquid transfer device (for example, a pump) 8 is operated, the cleaning liquid in the reservoir 1 ₃ of the vessel 1 ₂ is sucked out of the vessel 1 ₂ by the transfer device 8 and is applied by the transfer device 8. The ink is forced to reach the nozzle 7 and is sprayed from the spout 7 ₁ toward the ink fountain A to wash away the ink adhering to the ink fountain A. However, in this state, the ink fountain A cannot be evenly washed, so this method is not suitable for this design. By operating the drive device 6, the support shaft 3 is rotated and reciprocated in the longitudinal direction of the support shaft 3, so that the cleaning liquid sprayed from the nozzle 7 is evenly radiated both inside and outside the ink fountain A. It provides a complete cleansing.

In addition, since the above-mentioned cleaning operation is performed with the opening 11 of the sealed container 1, that is, _the container body ₁₂ , being closed with the lid 2, the cleaning liquid is not scattered outside the container 1 during the cleaning operation. Can be washed.

The cleaning liquid in the container 1 is sucked out from the reservoir ₁₃ by a transfer device 8 such as a pump, transferred to the nozzle 7, and sprayed from the spout ₇₁ to the ink fountain A, which is the object to be cleaned.
and falls into the reservoir ₁₃ again. If a filter device 10 is provided between the container 1 and the pump during such circulation of the cleaning liquid, the dirty cleaning liquid will be filtered out and a clean cleaning liquid with no ink mixed therein will be obtained.

After washing the ink fountain as described above, stop all operations of the washer, open the lid 2, and transfer the ink fountain A to the ink fountain A of the fuser body 3 ₁₂ fixed on the receiver 3 ₁₁ . By disengaging the ink fountain A
can be taken out of the container body ₁₂ .

Inkwell A taken out from container 1 ₂ is again placed in the 6th inkwell.
As shown in the figure, it is installed in the printing press and provided for the next printing job.

It is a sealed container that can be opened and closed, and the lid 2 is connected to the container body 1 ₂ by a hinge 1 ₄ so that it can be opened and closed. 3 is a support shaft that supports ink fountain A;
The support shaft 3 has a support portion 3 ₁ formed by screwing together a bolt-shaped fixing body 3 ₁₂ that protrudes from the lower surface side toward the upper surface of a rectangular bar-shaped receiver 3 ₁₁ , and the ink fountain A is attached to the receiver 3 11 . 3 _1
A bolt-shaped fixing body ₃₁₂ is fixedly positioned on the receiving body 311 and screwed onto the lower surface of the fixing body 312, so that the ink fountain A can be detachably fixed to the receiving body ₃₁₁ . Furthermore, the left end of the support shaft 3 is a rotatable shaft with a cylindrical shape, and the right end has a bolt-shaped slider 5 ₁ with a thread and is supported by the container body 1 ₂ . The support of the support shaft 3 by this container body ₁₂ is such that the cylindrical shaft ₃₂ of the support shaft 3 is supported by a bearing 4 that can rotate and slide in the longitudinal direction of the shaft, and a bolt The shaped slider 5 ₁ engages with the nut-shaped slider receiving portion 5 ₂ to constitute the shaft moving device 5 , and when the support shaft 3 rotates, it is guided to the slider receiving portion 5 ₂ and moves the slider 5 . ₁ can move to the left or right. The means for moving the support shaft 3 in the longitudinal direction of the shaft is not limited to the above-mentioned embodiments, but may be any means that can move the support shaft 3 in the longitudinal direction while rotating. Furthermore, the means for positioning and fixing the ink fountain A on the receptor 3 ₁₁ is not limited to the above embodiment, and any means that can position and fix the ink fountain A on the receptor 3 ₁₁ may be used.

Ink fountain A is installed in printing machine B in contact with ink roller C, and the ink in ink fountain A that is taken out by ink roller C is transferred to the next ink roller and is deposited on the original plate for printing at the final stage. It is used for printing.

In the embodiment, the ink fountain A can be washed two times, but this number is not limited to the example. For single-color printing, it is sufficient that the ink fountain A can be washed one time, and for multi-color printing or color printing. In the case of printing such as photographs, it is sufficient that several parts can be washed at once, and the number is not specified.

[Effect of idea]

As mentioned above, this idea has the biggest disadvantage in that conventional cleaning operations for cleaning ink fountain A stained with ink during printing operations seriously contaminate hands, etc., and waste cleaning fluid. However, since it was difficult to perform accurate and reliable cleaning in a short period of time, the cleaning solution was sprayed powerfully into the ink fountain A in a sealed container 1, and the spray was evenly distributed over the entire ink fountain. Since the ink fountain A is cleaned accurately and reliably, no ink remains, and
It is efficient because the work can be done in a short time, and there is no need to stain the worker with ink-containing cleaning solution.
When the cleaning liquid is an organic solution, it is highly safe because it prevents the cleaning liquid from scattering or evaporating and causing hygiene problems such as inhalation by workers.
