Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ink container instrumentation wearing location for mounting the ink container containing an ink with a viscosity in the printing machine.
[0002]
[Prior art]
Ink containers used in printing presses such as stencil printers store a flexible inner bag in an outer box made of corrugated paper, etc., and remove the ink dispensing tube provided at the end of the inner bag. There are some which are configured to protrude outward from the inside of the box and to seal the protruding end with a cap. As an example, for example, a cartridge container described in JP-A-8-90787 can be cited.
[0003]
On the other hand, inks used in printing machines such as stencil printing machines are relatively viscous and difficult to flow. Therefore, in order to supply ink to the printing unit, it is necessary to suck the ink in the ink container with an ink pump. As a specific structure, a support for supporting the ink container in the direction in which the ink dispensing tube extends in the horizontal direction is provided, and the support is displaced in the horizontal direction together with the ink container. There is one configured to connect the ink outlet pipe of the ink container to the suction port of the ink pump. As an example, for example, a device described in Japanese Utility Model Laid-Open No. 7-26133 is cited.
[0004]
Nowadays, environmental regulations are strict in any industrial field, and the above ink containers are no exception. It is required to save resources and reduce waste. Therefore, there is a tendency to use an ink container in which an outer container for protecting the ink bag is omitted by simply connecting an ink outlet tube sealed with a cap to one end of the flexible ink bag.
[0005]
[Problems to be solved by the invention]
The operation of removing the cap from the ink dispensing tube of the ink container is generally performed with the ink dispensing tube facing upward, from a conventional and ergonomic viewpoint. Therefore, as described above, in order to connect the ink container to the ink pump, in the configuration in which the ink container is set on the support with the ink discharge pipe oriented horizontally, the ink container is mounted on the support. In many cases, the cap is removed from the ink pipe.
[0006]
However, when using a resource-saving ink container in which the outer box is omitted, the ink bag is deformed by the gripping force when the ink bag is gripped by one hand against the force of removing the cap. As a result, there is a problem that the ink is discharged from the ink discharge pipe to the surroundings even though the ink is viscous.
[0007]
The present invention has been made in view of the above problems, even in the case of using the ink container of resource saving type, and an object thereof is to allow preventing the ink ejection accident during cap removal operation of the cap.
[0008]
[Means for Solving the Problems]
[0010]
According to the first aspect of the present invention, there is provided an ink pump for sucking ink whose viscosity is set to a predetermined value, and a highly rigid ink injection sealed with a cap at one end of a flexible ink bag for storing the ink. a container support comprising a dispensing tube support portion for detachably supporting the ink spout tube of the ink container made by combining together decane in fitted state, the pouring and before hearing Nki dispensing tube A structure for detent consisting of a protrusion formed on the ink dispensing tube and a locking recess formed on the dispensing tube support, which engage with each other in a state in which the tube support is fitted, An opening position for opening the cap with the ink outlet tube of the ink container supported by the container support facing upward, and a suction port of the ink pump after the cap is opened A lying position where the ink dispensing pipe falls on the center line passing through the center. Rotation support means for rotatably supporting the container support between the container support and the container support positioned at the lying position in a direction of approaching and separating from the suction port of the ink pump in a substantially horizontal direction. And an ink container mounting device provided with guide means for movably supporting the ink container.
[0011]
Therefore, in a state where the container support is supported at the opening position, the ink container can be attached to the container support with the ink dispensing tube facing upward. In this state, the cap can be opened without holding the ink bag in a stable state where the ink container is supported by the container support. When the container support is rotated to the lying down position by the rotation support means, guided by the guide means and moved toward the suction port of the ink pump, the ink discharge pipe of the ink container is connected to the suction port of the ink pump.
