Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ink supply device that supplies ink to a porous printing body made of materials such as rubber, ceramics, glass, polyethylene, and polypropylene.
[0002]
[Prior art]
As a conventional ink supply device in which ink is held in a container, a brush is provided on the back of the lid of an ink bottle as in Japanese Utility Model Publication No. 54-25256, and a bottle or container as in Japanese Utility Model Publication No. 58-54372. A configuration in which an ink is applied by providing an application portion at the mouth, and a device in which a moisture absorbing member is provided inside to suck up ink as disclosed in Japanese Utility Model Publication No. 62-4527 are known.
However, each of these conventional ink supply devices has the following problems.
In Japanese Utility Model Publication No. 54-25256, since ink is supplied by a brush, the amount of ink supplied cannot be regulated, and there is a drawback that excessive ink is supplied.
Japanese Utility Model Publication No. 58-54372 has a configuration in which an application portion is held at the opening portion of the ink container, and the ink is applied by being pressed downward against the application portion. Accordingly, since the ink is used in a downward direction, there is a drawback that excessive ink flows from the application portion.
Japanese Utility Model Publication No. 62-4527 uses a suction member to suck up a liquid and supply the liquid from the tip. However, since this is also used upside down, there is a drawback that it is not possible to prevent ink blowing out and excessive ink supply, and a certain amount of ink cannot be supplied.
[0003]
[Problems to be solved by the invention]
As described above, the conventional ink supply tool has to be used with the container upside down, and is not suitable for supplying a certain amount of ink.
Accordingly, the present invention has been invented for the purpose of supplying ink to a porous printing body while keeping the container upright without being inverted.

[Example 1]
Hereinafter, the present invention will be described in detail by way of examples.
FIG. 1 shows the first embodiment.
Reference numeral 1 denotes a main body container having one end as an open end 3 and the other end as a bottomed portion 2. In the center of the bottomed portion 2 of the main body container 1, a support portion 4 that holds an ink supply body 6 described later is provided, and on the inner wall of the opening end 3 of the main body container 1, a rib 5 that holds the ink supply body 6 is provided. It is. The support portion 4 has a shape that does not hinder the inflow of ink into the ink supply body 6 and is provided with an ink inlet and a slit. The rib 5 has a shape provided with an air inlet or a slit so that air can be replaced.
Reference numeral 6 denotes an ink supply body, in which the lower part is an ink storage part 7 and the upper part is an ink donating part 8. The ink occlusion unit 7 is a bottomed cylindrical body having a shape in which one end of a cylinder is closed, and has an opening part downward and a closing part upward. Since the ink occlusion part 7 is hollow inside, the ink occlusion part 7 can be in contact with the ink over a wide area and can sufficiently absorb and hold the ink. The ink supply unit 8 is fixed to the closing portion of the ink storage unit. In the present embodiment, the ink supply unit 8 and the ink storage unit 7 are heated and melted and bonded and fixed to the contact portions on the outer peripheral side surfaces (bonding unit 9).
The main body container 1 contains ink 10.
[0006]
As for the material, the ink occlusion part 7 can be selected from natural fibers (cotton, hemp, etc.), synthetic fibers (polyester, nylon, etc.), synthetic resins (polyester, polypropylene, vinyl chloride, urethane, rubber, etc.), etc. In this embodiment, a polyester resin made of a porous body having open cells is used. The ink donating unit 8 can be made of the same material as the ink occluding unit 7, but in this embodiment, a polyester resin made of a porous material is used.
However, in the above case, the ink donating unit 8 must have a larger capillary force than the ink storage unit 7. This is because if the ink supply unit 8 is not always supplied with ink from the ink storage unit 7, ink cannot be supplied while the main body container 1 is in an upright state. In this embodiment, in order to provide a difference in capillary force, those having different bubble diameters are used. The ink occlusion unit 7 has a bubble diameter of 200 μm, and the ink supply unit 8 has a bubble diameter of 10 μm so as to satisfy the above conditions. ing.
[0007]
In the present invention, ink is supplied to the porous printing body 12 as follows.
First, the ink 10 is sucked up by the ink occluding portion 7, and the ink occluding portion 7 is saturated. Although the ink occlusion part 7 is relatively inferior in ink absorption, it is in the form of a bottomed cylindrical body having a hollow inside, so that it can be in contact with ink over a wide area and sufficiently absorbs and retains ink. be able to.
Next, since the pore sizes of the ink storage unit 7 and the ink supply unit 8 are changed, the capillary force of the ink becomes “ink storage unit <ink supply unit”, and the ink supply unit 8 always receives ink from the ink storage unit 7. Sucking up and keeping a certain amount of ink.
When the porous printing body 12 is put on the ink supply unit 8 in such a state, the porous printing body 12 starts to absorb ink, and the ink holding power of the porous printing body 12 and the ink holding power of the ink supply unit 8 are increased. When the equilibrium is reached, the ink supply ends.
Therefore, a constant ink is always supplied without excessively supplying ink to the porous printed body.
[0008]
[Example 2]
Next, Example 2 is shown in FIG.2 and FIG.3. A description of the same parts as those in the first embodiment will be omitted.
The ink supply 6 'has a lower portion as an ink storage portion 7' and an upper portion as an ink supply portion 8 '. The ink occlusion part 7 'is a bottomed cylindrical body having a shape in which one end of a cylinder is closed, and has an opening part downward and a closing part upward.
In this embodiment, eight reinforcing portions 13 'are erected in a radial pattern from the center of the closed portion of the ink occlusion portion 7'. In this way, when the porous printing body is pressed against the ink supply portion 8 'by applying pressure to the stamp to quickly supply the ink, the reinforcing portion 13' causes the entire ink supply body to be distorted. Not only can this be prevented, but the volume of the closed portion can be increased to hold more ink.
The reinforcing portions do not necessarily stand up to eight as in this embodiment, but a plurality (two or more) of the reinforcing portions may be provided radially from the center of the closed portion, or a plurality of vertical and horizontal standing in a lattice shape. May be.
Regarding the material, the ink occluding portion 7 'can be selected from natural fibers (cotton, hemp, etc.), synthetic fibers (polyester, nylon, etc.), synthetic resins (polyester, polypropylene, vinyl chloride, urethane, rubber, etc.), etc. However, in this embodiment, a polyester resin made of a porous body having open cells is used. The ink supply unit 8 'can be made of the same material as the ink storage unit 7', but in this embodiment, a polyester resin made of a porous material is used. In this embodiment, the ink occlusion unit 7 'has a bubble diameter of 200 μm and the ink supply unit 8 ′ has a bubble diameter of 10 μm. It is set so that the ink supply can always be received from the ink storage section 7 '.
Further, the hardness of the ink occlusion unit 7 'is set higher than the hardness of the ink donating unit 8'. In this embodiment, the hardness of the ink occlusion part 7 'is set to 88 (measured with a JIS A type rubber hardness meter), and the hardness of the ink donating part 8' is set to 20 (measured with a JIS A type rubber hardness meter). It is.
With this setting, when the stamp is pressed with a slight inclination, only the ink supply part 7 'is inclined together, so that the entire contact surface of the porous print body and the ink supply part 8' is in close contact and the ink permeates uniformly. Will be. (The ink occlusion unit 7 'is harder than the ink supply unit 8' and therefore does not tilt, and the entire ink supply unit is prevented from tilting and becoming unstable.)
Further, if the seal is released, the ink supply unit tries to restore the original shape, and at that time, the ink is sucked up and the instantaneous ink transfer to the ink supply unit is promoted.
