This application is a 371 of International Application PCT/JP2010/003236 filed 13 May 2010 entitled “Printing Blanket, Printer And Method For Producing Printing Blanket”, which was published on 9 Sep. 2011, with International Publication Number WO 2011/108034 A1, and which claims priority from Japanese Patent Applications No. 2010-49269 filed on 5 Mar. 2010 and 2010-97747 filed on 21 Apr. 2010, the content of which is incorporated herein by reference.
The present invention generally relates to printing blankets, printing devices, and methods of manufacturing printing blankets, and particularly relates to a printing blanket suitable for pad printing that involves picking up ink and transferring the picked-up ink to a to-be-printed surface, a printing device having the printing blanket, and a method of manufacturing the printing blanket.
Pad printing is a conventional process in which a printing blanket (i.e., a printing pad) is pressed against a printing original plate (i.e., an image plate), on which ink is disposed in accordance with a printing pattern, so as to transfer (pick up) the ink from the printing original plate, and then the printing blanket is pressed against a to-be-printed surface so as to transfer (deliver) the ink to a to-be-printed surface, whereby the printing pattern is printed onto the to-be-printed surface. There is disclosed an invention in which, in order to prevent reduction in the printing quality, a printing original plate is reciprocally moved so as to shake and stir ink in an ink box that is in contact with the printing original plate and thereby make the ink less likely to be cured (see Patent Literature 1, for example).
Patent Literature 1: Japanese Unexamined Patent Application Publication No. 2008-114496 (Pages 9-10, FIG. 1)
According to the invention disclosed in Patent Literature 1, a printing blanket is an elastic body made of silicone rubber or the like containing silicone oil so as to impart elasticity (flexibility), and is formed in a substantially hemispherical shape (bullet shape) or a substantially semi-cylindrical shape (bullet-shaped cross section). Further, in order to make the printing blanket fit to the to-be-printed surface, the printing blanket needs to be soft (i.e., have a low elastic modulus and be easily elastically deformed).
However, when the printing blanket is pressed onto the printing original plate and is deformed, silicone oil in the printing blanket may come out to the surface thereof, or the printing blanket may become locally worn or damaged, which results in the following problems.
(a) It becomes difficult to transfer (deliver) the ink from the printing original plate to the printing blanket, which results in a blurred or unclear printing pattern being printed on the to-be-printed surface.
(b) Further, ink and silicone oil accumulate on the printing original plate, and the resulting excessive amount of ink and oil contaminate the printing original plate. The contaminants are transferred to the printing blanket, which results in a smeared printing pattern being printed on the to-be-printed surface.
(c) Furthermore, in the case of removing ink not having been picked up and remaining on the printing original plate, frequent cleaning may cause damage to the printing original plate and roughen the surface thereof, which may reduce the service life of the printing original plate. This leads to frequent replacement with a new printing original plate, resulting in increased printing costs (equipment costs).
(d) In the case of applying a coating to the to-be-printed surface with the printing pattern printed thereon, the coating is repelled by the silicone oil component, and therefore a desired coating cannot be formed.
(e) On the other hand, in the case where the hardness of the printing blanket is increased, it becomes difficult to print the printing pattern across a wide area on a curved surface. Then, the printable area is reduced, which may result in reduced design properties of the printing pattern. In the case of printing the printing pattern across a wide area, it is necessary to perform small area printing a plurality of times, which increases the print costs.
(f) Further, since the ink is transferred to the to-be-printed surface by pressing the printing blanket against the flat printing original plate and the curved to-be-printed surface, the distal end (the lowermost point or the lowermost line) of the printing blanket and the portion in the vicinity thereof become particularly degraded or damaged, or the printing blanket may become damaged by a protruding portion of the to-be-printed surface. Such local degradation or damage makes the printing blanket unusable, and thus the entire printing blanket is discarded.
The present invention has been made to overcome the above problems. A first object of the present invention is to provide a printing blanket that excellently fits to a curved to-be-printed surface while preventing silicone oil contained in the printing blanket from coming out to the surface of the printing blanket when the printing blanket is deformed. A second object of the present invention is to provide a printing device having the printing blanket. A third object of the present invention is to provide a method of manufacturing a printing blanket that, even if the printing blanket is locally degraded or damaged, does not need to be discarded entirely and can perform high-quality printing.
(1) According to the present invention, there is provided:
a printing blanket that is configured to pick up ink, which has been applied to a printing original plate in accordance with a printing pattern, from the printing original plate by being pressed against the printing original plate and then deliver the picked-up ink to a to-be-printed surface by being pressed against the to-be-printed surface, and thereby print the printing pattern on the to-be-printed surface, the printing blanket including a double-layer structure having:
a flexible elastic body containing silicone oil; and
a lesser-flexible coating layer containing silicone oil and covering a part of a surface of the elastic body.
(2) With regard to (1) described above, the elastic body has a cylindrical shape, and the coating layer covers an outer circumferential surface of the main body.
(3) With regard to (1) described above, the elastic body has a substantially semi-cylindrical shape, a substantially conical shape, or a substantially pyramidal shape, and the coating layer covers a predetermined area of the elastic body containing an apex thereof.
(4) With regard to (3) described above, the thickness of the coating layer is greater at the apex of the elastic body and in the vicinity of the apex than at a position away from the apex.
(5) Further, according to the present invention, there is provided:
a printing device including:
the printing blanket of any one of (1) through (4);
a pad mounting unit on which the printing blanket is disposed;
a moving unit configured to movably support the pad mounting unit;
a controller configured to control movement of the moving unit; and
a main body in which the moving unit and the controller are disposed.
(6) Further, according to the present invention, there is provided:
a method of manufacturing a printing blanket including an elastic body having a substantially semi-cylindrical shape and a sheet bonded to a side surface of the elastic body having a substantially arcuate cross section, the method including the steps of:
molding an elastic body having a substantially semi-cylindrical shape;
forming a sheet having a predetermined size;
placing the sheet on a flat surface;
pressing a side surface of the elastic body against the placed sheet; and
applying an adhesive to one or both of the side surface of the elastic body and a surface of the sheet against which the elastic body is to be pressed, prior to the pressing step;
wherein the sheet is bonded to the side surface of the elastic body in the pressing step.
(7) With regard to (6) described above, the method further includes the step of applying a mold release agent to any one of the side surface of the elastic body, the surface of the sheet against which the elastic body is to be pressed, and the adhesive.
(8) With regard to (6) or (7) described above, the sheet and the elastic body contain silicone oil, and the sheet is less flexible than the elastic body.
(i) A printing blanket according to the present invention includes a double-layer structure having a flexible elastic body and a lesser-flexible coating layer covering a part of the surface of the elastic body, and therefore excellently fits to a curved to-be-printed surface. Thus, when the printing blanket is deformed, silicone oil contained in the elastic body is substantially blocked by the lesser-flexible coating layer covering the surface of the elastic body, which makes the silicone oil less likely to come out to the surface of the coating layer. Accordingly, it is possible to solve the problems (a) through (d) described above. The number of coating layers is not limited to one. That is, in the case where two, three, or more coating layers are provided, the printing blanket has a three-layer structure, a four-layer structure, or a multi-layer structure having more than four layers.
It should be noted that, in this specification, an elastic body is not limited to those in which the relationship between a load applied thereto and the amount of deformation due to the applied load is liner, but may include those in which that relationship is non-linear and which returns to the original shape immediately after or with a delay of a predetermined time period from when a load having been applied thereto is removed.
Further, “flexible” and “soft” refer to a property of being easily deformed by application of a relatively lower load. For example, in the case of the materials that linearly deform elastically, “flexible” and “soft” are equivalent to having a low elastic modulus. On the other hand, “lesser-flexible” and “hard” refer to a property of requiring a “relatively higher load” to be applied for deformation compared to that required by a substance that is “flexible” or “soft”.
(ii) Further, since the thickness of the coating layer is greater at the apex of the elastic body, which is more likely to be worn (degraded or damaged) due to a higher load applied thereto, than in the other area, it is possible to prevent the service life from being reduced due to local wear.
(iii) A printing device according to the present invention has a printing blanket that solves the problems (a) through (e) described above, and therefore can print a clean printing pattern at low cost.
(iv) According to a method of manufacturing a printing blanket of the present invention, the side surface of an elastic body is pressed against a sheet disposed on a flat surface, and thus a printing blanket including an elastic body having a side surface with the sheet bonded thereto is manufactured. That is, the lowermost portion of the side surface of the elastic body comes into contact (line contact) with the sheet. Then, as the elastic body is pressed further, the contact area gradually expands from that position. Therefore, air is prevented from being trapped on the contact surface (i.e., the bonding surface).
Accordingly, it is possible to pick up ink, which has been applied to a printing original plate in accordance with a printing pattern, from the printing original plate accurately (i.e., while preventing a part of the ink from not being picked up (from remaining thereon)), and transfer the ink to a to-be-printed surface accurately. The sheet can be manufactured at low cost, and it is easy to remove a degraded or damaged sheet from the elastic body and bond a new sheet thereto. This allows the elastic body to be used repeatedly and thereby achieves low printing costs.
(v) Further, a mold release agent may be applied to any one of the side surface of the elastic body, the surface of the sheet against which the elastic body is pressed, and the adhesive so as to facilitate replacement of sheets.
It should be noted that the elastic body is made of the same material as related-art printing blankets. Further, although the material of the sheet is not particularly limited, the sheet is capable of picking up ink, which has been applied to a printing original plate (not shown) in accordance with a printing pattern, from the printing original plate when being pressed against the printing original plate, and is capable of delivering the picked-up ink to a to-be-printed surface when being pressed against the to-be-printed surface. Accordingly, the sheet has the substantially same function as the elastic body.
(vi) Moreover, the sheet has elasticity (flexibility) so as to excellently fit to a curved to-be-printed surface. Thus, when the elastic body is deformed, silicone oil contained in the elastic body is substantially blocked by the lesser-flexible sheet covering the surface of the elastic body, which makes the silicone oil less likely to come out to the surface of the coating layer. Accordingly, it is possible to solve the problems (a) through (e) described above.
(vii) The sheet may be less flexible than the sheet in order to make the substantial blocking effect by the sheet more pronounced. The present invention, however, is not limited thereto.
Embodiment 1: Printing Blanket
Referring to
The elastic body 1a and the coating layer 1d contain silicone oil in order to ensure transfer (pick-up and deliver) of ink and to impart elasticity (flexibility) thereto. The coating layer 1d is harder (contains a smaller amount of silicone oil) than the elastic body 1a.
Accordingly, the elastic body 1a is easily deformed, and the coating layer 1d is deformed in accordance with deformation of the elastic body 1a. Therefore, the printing blanket 1 excellently fits to the curved to-be-printed surface. Further, when the printing blanket 1 is deformed, the silicone oil contained in the elastic body 1a is substantially blocked by the coating layer 1d surrounding the elastic body 1a. Also, the content of the silicone oil in the coating layer 1d is small. Therefore, the silicone oil is less likely to come out to a surface 1e of the coating layer 1d.
It should be noted that, in the present invention, the number of coating layers 1d is not limited to one, and additional one, two, or more coating layers may be provided on top of the coating layer 1d. In this case, the printing blanket 1 has a three-layer structure, a four-layer structure, or a multi-layer structure having more than four layers.
The coating layer 1d is bonded to the elastic body 1a. Therefore, in the case where the coating layer 1d is worn (degraded or damaged), the entire or a part of the worn coating layer 1d may be removed such that a new coating layer may be formed thereon by using a coating process or the like. In this case, the printing blanket 1 has a double-layer structure formed of the original elastic body 1a and a new coating layer, or has a three-layer structure formed of the original elastic body 1a, a part of the worn original coating layer 1d, and a new coating layer.
It should be noted that, although the entire (360 degrees) outer circumferential surface of the elastic body 1a is covered by the coating layer 1d in the above description, the present invention is not limited thereto. For example, half the outer circumferential surface (180 degrees) or a third of the outer circumferential surface (120 degrees) of the elastic body 1a may be covered by the coating layer 1d. Further, in place of a cylindrical shape, the elastic body 1a may have a semi-cylindrical shape such that a part or a front portion of the arcuate surface thereof may be covered by a coating layer.
Since the printing blanket 1 is formed such that the silicone oil is less likely to come out to the surface 1e, the following advantageous effects are obtained.
(A) Ink applied to a printing original plate (not shown) is reliably transferred to the printing blanket 1. This allows a printing pattern (not shown) to be clearly printed on a to-be-printed surface.
(B) Ink is prevented from accumulating on the printing original plate (not shown), whereby the printing original plate is prevented from being contaminated. This allows a printing pattern to be printed clean without any smear (not shown).
(C) Further, there is no need to frequently clean the printing original plate (not shown), which prevents the surface thereof being roughened and thus extends the service life thereof. This reduces the frequency of replacing with a new printing original plate, resulting in reduced printing costs (equipment costs).
(D) In the case where the coating layer is worn (degraded or damaged), the printing blanket can be used continuously only by replacing the entire or a part of the coating layer 1d without replacing elastic bodies, which results in low material costs.
(E) Further, it is possible to print a printing pattern across a wide area on a curved surface using a single printing blanket 1. This simplifies the printing process and thereby reduces the printing costs. This also makes it possible to impart design properties to the printing pattern and thereby enhances the commercial value of the print object.
(F) Furthermore, even in the case of applying a surface treatment such as coating onto the to-be-printed surface, since there is little silicone oil adhering the to-be-printed surface, the coating is prevented from being repelled by the silicone oil, which allows a high-quality to-be-printed surface (coating surface) to be obtained.
Referring to
The elastic body 2a has a substantially arcuate triangular cross section with the side faces 2b projecting outward. The adjacent side faces 2b are smoothly connected to each other, and the apex 2c where the four side faces 2b meet has a substantially partial spherical shape.
The elastic body 2a and the coating layer 2d contain silicone oil in order to ensure transfer (pick-up and deliver) of ink. The coating layer 2d is harder than the elastic body 2a.
Accordingly, the elastic body 2a is easily deformed, and the coating layer 2d is deformed in accordance with deformation of the elastic body 2a. Therefore, as in the case of the printing blanket 1 of Example 1, the printing blanket 2 excellently fits to the curved to-be-printed surface, and the silicone oil is less likely to come out to a surface 2e of the coating layer 2d.
It should be noted that, although a part of the side faces 2b containing the apex 2c of the elastic body 2a is covered by the coating layer 2d in the above description, the present invention is not limited thereto. The entire side faces 2b may be covered by the coating layer 2d. Further, in place of a substantially quadrangular pyramidal shape, the elastic body 2a may have a shape similar to a three-sided pyramid, or a five or more-sided pyramid. The elastic body 2a may have a conical shape with a rounded apex.
Referring to
The elastic body 3a and the coating layer 3d contain silicone oil in order to ensure transfer (pick-up and deliver) of ink. The coating layer 3d is harder than the elastic body 3a. Further, since the apex 3c and a portion in the vicinity of the apex 3c are more likely to be worn (degraded or damaged) due to high pressure applied thereto, the thickness of the coating layer 3d is greater in this area than in the area away from the apex 3c.
Therefore, as in the case of the printing blanket 1 of Example 1, the printing blanket 3 excellently fits to the curved to-be-printed surface, and the silicone oil is less likely to come out to a surface 3e of the coating layer 3d. Further, although the apex 3c and a portion in the vicinity of the apex 3c are more likely to be worn due to high pressure that is applied thereto due to a pressing motion upon picking up the ink and upon delivering the ink to the to-be-printed surface, since the thickness of the coating layer 3d is greater in the vicinity of the apex 3c, the service life of the printing blanket 3 is extended.
Further, only by forming a new coating layer for only a worn portion or only a predetermined area containing the worn portion, the original printing blanket 3 and the remaining portion of the original coating layer 3d can be used continuously. Therefore, with inexpensive repairs, the printing blanket 3 can be used for a long period of time. Furthermore, as in the case of the printing blanket 1, a wide area of the coating layer 3d may be replaced. This results in low component costs.
It should be noted that the shape of the elastic body 3a is not limited and may have a shape similar to a cone or pyramid, or a semi-cylindrical shape. Further, the size of the area covered with the coating layer 3d is not limited as long as the area contains the apex 3c.
Embodiment 2: Printing Device
Referring to (a) of
The main body 11 includes a main body base 11a, a main body stand 11b fixed to the main body base 11a, and a main body rail 11c fixed to the upper end of the main body stand 11b.
The moving unit 12 includes an X-direction moving beam 12x movably supported by (disposed on or suspended on) the main body rail 11c, a Y-direction moving beam 12y movably supported by (disposed on or suspended on) the X-direction moving beam 12y, and a lifting unit 12z that is disposed on the Y-direction moving beam 12y and is configured to lift and lower the pad mounting unit 13.
The pad mounting unit 13 includes a mounting bar 13a configured to be lifted or lowered by the lifting unit 12z, and a mounting plate 13b fixed to the lower end of the mounting bar 13a. The printing blanket 2 is mounted on the lower surface of the mounting plate 13b.
The controller 14 moves the moving unit 12 so as to perform printing in accordance with an entered predetermined printing procedure. That is, the printing blanket 2 is moved to a position facing a printing original plate (i.e., an image plate) 4 on which ink is disposed in accordance with a printing pattern, and is lowered to be pressed against the printing original plate 4, so that the ink is transferred to (picked up by) the printing blanket 2. Then, the printing blanket 2 is lifted, is moved to a position facing a print object 5, and is lowered so as to transfer (deliver) the ink to a to-be-printed surface. Thus, a printing pattern is printed on the surface of the print object 5.
Thus, since the printing device 10 includes the printing blanket 2 (Example 2), it is possible to print a clear and clean printing pattern on the to-be-printed surface at low costs. It is also possible to enhance the commercial value of the print object by printing a printing pattern with design properties imparted thereto.
It should be noted that the printing blanket 1 or the printing blanket 3 may be used in place of the printing blanket 2.
Further, the moving unit 12 illustrated in the above description is formed of members that move in three directions, respectively. However, the present invention is not limited there to, and the moving unit 12 may include a robot whose distal end is movable in three directions.
Referring to (b) of
The main body 21 includes a main body base 21a, a main body stand 21b fixed to the main body base 21a, and a main body rail 21c fixed to the upper end of the main body stand 21b.
The moving unit 22 is movably supported by (suspended on) the main body rail 11c, and is configured to move itself in accordance with a control signal from the controller 24.
The pad supporting unit 23 has an end mounted on the moving unit 22 and the other end rotatably supporting the center of the printing blanket 1.
The controller 24 moves the moving portion 22 so as to perform printing in accordance with an entered predetermined printing procedure. That is, when the moving unit 22 moves rightward, the printing blanket 1 rotates while being pressed against a printing original plate (i.e., an image plate) 4 on which ink is disposed in accordance with a printing pattern, so that the ink is transferred to (picked up by) the printing blanket 1. Then, when the moving unit 22 moves leftward, the printing blanket 1 rotates while being pressed against a print object 5 so as to transfer (deliver) the ink to a to-be-printed surface. Thus, a printing pattern is printed on the surface of the print object 5.
In order to prevent the surface le of the printing blanket 1 from sliding with respect to the surface of the printing original plate 4 and to prevent the surface le of the printing blanket 1 from sliding with respect to the surface of the print object 5, the moving speed of the moving unit 22 is equal to the peripheral speed of the surface 1e.
Thus, since the printing device 20 includes the printing blanket 1 (Example 1), it is possible to print a clear and clean printing pattern on the to-be-printed surface at low costs. It is also possible to enhance the commercial value of the print object by printing a printing pattern with design properties imparted thereto.
Embodiment 3: Method of Manufacturing Printing Blanket
Referring to
The elastic body 31 includes a side face 31a defining a convex surface, another side face 31b that is plane-symmetric to the side face 31a, a ridge line 31c (technically, this portion has a certain width, but is referred to as a “line” for explanation purposes) smoothly connecting between the side surface 31a and the side surface 31b, and a mounting surface 1d serving as a mounting surface to be attached to a printing apparatus (not shown).
It should be noted that the ridge line 31c defines the lowermost end of the elastic body 31. Further, the cross sections of the side faces 31a and 31b do not have a perfect semicircular shape, but have a bullet shape (see (a) of
The sheet 32 has a rectangular shape with a predetermined thickness (e.g., 1 mm), and is capable of picking up ink, which has been applied to a printing original plate (not shown) in accordance with a printing pattern, from the printing original plate when being pressed against the printing original plate, and is capable of delivering the picked-up ink to a to-be-printed surface (not shown) when being pressed against the to-be-printed surface. The material (substance) thereof is not particularly limited.
The elastic body 31 is also capable of picking up ink, which has been applied to a printing original plate (not shown) in accordance with a printing pattern, from the printing original plate through the sheet 32 when being pressed against the printing original plate, and is capable of delivering the picked-up ink to a to-be-printed surface (not shown) through the sheet 32 when being pressed against the to-be-printed surface. The material (substance) thereof is not particularly limited.
Next, a description will be given of a manufacturing method with reference to
An elastic body 31 having a substantially semi-cylindrical shape (a bullet-shaped cross section) is molded.
Also, a sheet having a predetermined size (thickness, vertical length, and horizontal length) is formed. The sheet may be obtained by molding a sheet into a predetermined size, or by cutting a large sheet into a rectangle of a predetermined size.
Subsequently, the sheet 32 is placed on a flat surface 33 (see (b) of
Then, an adhesive (not shown) is applied to the side faces 31a and 1b and the ridge line 31c, and the elastic body 31 is lowered in the normal direction of the flat surface 33 so as to be pressed against the sheet 32 (see (a) and (b) of
Then, when the entire surface of the sheet 32 comes into contact with (is bonded to) the elastic body 31, lowering of the elastic body 31 is stopped.
Then, immediately after stopping lowering of the elastic body 31, or after maintaining the elastic body 31 in a pressed state for a predetermined time period after stopping lowering of the elastic body 31, the elastic body 31 is lifted. Thus, the elastic body 31 returns to the original shape. In this way, a printing blanket 30 formed of the elastic body 31 with the sheet 32 bonded thereto (see (c) of
Since the printing blanket 30 does not have any bubble (that is small enough to be invisible to the naked eye) trapped on the bonding surface of the sheet 32, it is possible to prevent a part of the to-be-printed surface from not being printed (prevent blank portions from remaining on the to-be-printed surface) and therefore to perform high-quality printing.
Moreover, the sheet 32 can be manufactured at low cost, and it is easy to bond the sheet 32 to the elastic body 31. Therefore, even if the surface of the sheet 32 is locally degraded or damaged due to use, the degraded sheet 32 can be removed and replaced with a new sheet 32 at low cost. This allows high-quality printing to be performed continuously at low cost.
On the other hand, in the case of forming, in place of the sheet 32, a coating body having an inner surface that has a shape matching the shapes of the side faces 31a and 1b of the elastic body 31 and having a predetermined thickness by molding using a die, it is necessary to form a die for each shape of the elastic body 31, resulting in an increase in the manufacturing cost of the printing blanket. Further, when bonding the coating body to the elastic body 31, air is trapped between the inner surface of the coating body and the side faces 31a and 1b of the elastic body 31, and therefore high-quality printing cannot be performed.
It should be noted that, although an adhesive is applied to the elastic body 31 before the pressing step, the present invention is not limited thereto. An adhesive may be applied to the sheet 32 in place of the elastic body 31, or to both the sheet 32 and the elastic body 31. Further, the method of applying an adhesive is not particularly limited. An adhesive may be applied using a brush, or may be applied by spraying using a spray.
Further, the sheet 32 may be placed on a concave surface 34 having an arcuate cross section (see

Referring to (b) of
According to the present invention, a printing blanket excellently fits to a curved to-be-printed surface while preventing silicone oil contained in the printing blanket from coming out to the surface of the printing blanket when the printing blanket is deformed. Accordingly, the present invention is widely used as printing blankets of various shapes and sizes, and printing devices having the printing blankets. Further, a sheet is bonded to an elastic body while preventing air from being trapped therebetween, which allows high-quality printing to be performed. Therefore, it is possible to manufacture a printing blanket at low cost. Accordingly, the present invention can be widely used a printing blanket manufacturing method for manufacturing printing blankets of various shapes and sizes.
