Together with Fig. 2 to Fig. 5, the printing machine in this exemplary embodiment comprises referring to Fig. 1: workbench 50, be arranged on the virtual film feed lines, and this virtual film feed lines is in order to present film; Print roller 40, spaced apart and in order to be applied on the film on the workbench 50 by look being hindered agent with workbench 50, come the print surface (referring to Fig. 4) to film to carry out printing operation; And batcher 60, be arranged in a side of film feed lines, and in order to the non-print surface except print surface that grasps film to present film along the film feed lines.
And the printing machine in this exemplary embodiment comprises: intaglio plate 10, and spaced apart and have outer surface with workbench 50, look resistance agent is administered on this outer surface; Distributor 30 is in order to hinder look on the outer surface that agent is applied to intaglio plate 10; And scraper 20, contiguous distributor 30 is arranged and is removed unnecessary look resistance agent in order to the resistance of the look from the outer surface that is administered to intaglio plate 10 agent.
In this exemplary embodiment, intaglio plate 10 comprises gravure roll 10.Further, print roller 40 comprises that blanket covers roller (blanket roll) 40, blanket covers roller 40 and again is spread on the film on the workbench 50 in order to the look resistance agent that receives drawouts from gravure roll 10 and with this look resistance agent, and then the print surface of film is carried out printing operation.
Hereinafter, intaglio plate 10 will be called as gravure roll 10, and print roller 40 will be called as blanket and cover roller 40.Whether certainly, use gravure roll 10 or blanket to cover roller 40 and choose wantonly, this does not limit the scope of the invention.
Simultaneously, for ease of explanation, will illustrate sequentially that gravure roll 10, distributor 30, scraper 20, blanket cover roller 40 and workbench 50 and not according to its Ref. No., then batcher 60 and other elements will be described.
At first, gravure roll 10 is spread to the outer surface that blanket covers roller 40 for look is hindered agent.
Therefore, the top area of gravure roll 10 and the blanket length of covering roller 40 is approximate each other in size.Gravure roll 10 can be fixed on correspondence position.In this kind situation, blanket covers the look resistance agent that roller 40 moves and therefore sprawls from gravure roll 10 receptions towards gravure roll 10.
Then, distributor 30 is used for look is hindered the outer surface that agent is applied to gravure roll 10.Look resistance agent can be black ink, another kind of monochrome ink or polychrome printing ink.
Though unspecified, the outer surface of gravure roll 10 is formed with inhomogeneous pattern, and look resistance agent is adhered to (namely using) in this inhomogeneous pattern in fact.At this moment, inhomogeneous pattern can be that protrude or recessed.If inhomogeneous pattern protrudes, then look resistance agent is administered on the outer surface of protuberance 10b (referring to the amplifier section of Fig. 1) of protrusion and is spread to blanket and covers on the roller 40.And if inhomogeneous pattern is recessed, then look resistance agent is administered on the outer surface of groove 10a (referring to the amplifier section of Fig. 1) and is spread to blanket and covers on the roller 40.
When blanket covers that roller 40 receives the look resistance agent of sprawling from the outer surface of gravure roll 10 and this look resistance agent sprawled again (i.e. printing) to the film the time, for making the even thickness of the look resistance agent pattern on the film surface, making inhomogeneous pattern on the outer surface that is formed at gravure roll 10 have recessed form can be comparatively favourable.
When distributor 30 hindered look on the outer surface that agent is applied to gravure roll 10, look resistance agent in fact only must be administered to groove 10a (such as the amplifier section of Fig. 1).Yet, when distributor 30 hinders look on the outer surface that agent is applied to gravure roll 10, be difficult in fact at once look be hindered agent and use into look resistance agent optionally only is contained among the groove 10a.
Therefore, when distributor 30 hindered look on the outer surface that agent is applied to gravure roll 10, look resistance agent was sprawled widely and is applied on the whole outer surface of gravure roll 10.When using coloured resistance agent fully, remove and be administered to surperficial 10b but not look on groove 10a resistance agent (being unnecessary look resistance agent) can finally only be contained among the groove 10a Dry Sack resistance agent.For this reason, provide scraper 20, to remove gravure roll 10 unnecessary look resistance agent on every side.
The blade 22 that scraper 20 comprises hilt 21 and is coupled to hilt 21.

Because the end of blade 22 contacts with the outer surface of gravure roll 10, therefore when look hinders on the outer surface of gravure roll 10 that agent is administered to rotation, blade 22 can naturally scrape off and be administered to surperficial 10b but not look on the groove 10a hinders agent.Therefore, look resistance agent can finally only be contained among the groove 10a.
Opposite with gravure roll 10, scraper 20 can be movably.Though not shown, can use linear motor (linear motor) or similar device to the moving structure of scraper 20, be not limited in this.Alternatively, scraper 20 can be fixing, and gravure roll 10 can be movably.
Blanket covers roller 40 and receives the look resistance agent of sprawling from the outer surface of gravure roll 10 (namely being formed at the groove 10a (referring to Fig. 1) on the outer surface of gravure roll 10), and towards load on the workbench 50 and absorption and be attached to film on the workbench 50 and move and rotate in look hindered on the print surface that the agent pattern is printed on film.As mentioned above, the print roller 40 in this exemplary embodiment comprises that blanket covers roller 40.
The outer surface that covers roller 40 around blanket comes rolled sheet S, is spread on the thin plate S from gravure roll 10 look is hindered agent.Thin plate must be changed after reusing above the number of times of predetermined limits.Therefore, blanket covers roller 40 and is provided with thin plate replacing unit 41, to be used for easily changing thin plate.Thin plate is changed unit 41 not only makes thin plate S easily be changed, and gives the constant tension force of thin plate S, covers the external surface peripheral of roller 40 and can not relax thereby make thin plate S can be tightened up and be wound on blanket.
As mentioned above, in the printing machine according to this exemplary embodiment, must receive looks resistance agent and this look resistance agent is spread on the film on the workbench 50 again from gravure roll 10 because blanket covers roller 40, so blanket covers roller 40 and can move up and down, moves horizontally and rotate.
For this reason, blanket is covered roller 40 be connected to blanket and cover roller driver (not shown), with vertical movement, move horizontally and rotate blanket and cover roller 40.Described vertical movement, move horizontally and rotate and can pass through cylinder, linear motor and rotating motor respectively and easily realize, the detailed construction of therefore will be no longer blanket being covered the roller driver is given unnecessary details.

The major part of platform movement support 70 be coupled to the top of gripper shoe 58 and its only a part be coupled to the bottom of workbench 50, and then connect gripper shoe 58 and workbench 50.Platform movement support 70 comprises four movable support unit 70a～70d, and movable support unit 70a～70d is arranged at respectively four top corner location of gripper shoe 58.That is the arrangement form of four movable support unit 70a～70d will be called as rectangular layout.
Therefore, if four movable support unit 70a～70d are arranged to rectangular layout in four top corner zones of gripper shoe 58, then the supporting construction that has of this rectangular layout is more stable than general desired three-point type supporting structure.Therefore, even large blanket covers roller 40 and presses workbench 50 with high pressure during printing operation, workbench 50 can automatically not move yet.In other words, workbench 50 is subject to MIN promotion.It should be understood, of course, that workbench 50 can easily or efficiently accurately move along X-axis, Y-axis and θ axle.
For ease of explanation, will by counter clockwise direction these four movable support unit 70a～70d be called first to fourth movable support unit 70a～70d with respect to the regional A of Fig. 7.
First to fourth movable support unit 70a～70d comprises respectively: first to fourth motor 71a～71d; First to fourth ball screw 72a～72d is coupled to first to fourth motor 71a～71d and can passes through first to fourth motor 71a～71d and the rotation of ground, front and back; First to fourth swinging mounting 73a～73d is placed with relative with first to fourth motor 71a～71d and makes first to fourth ball screw 72a～72d between it, and in order to support rotationally the end of first to fourth ball screw 72a～72d; First to fourth movable block 74a～74d, when first to fourth ball screw 72a～72d rotated, described first to fourth movable block 74a～74d can move along the length direction of first to fourth ball screw 72a～72d; First to fourth intersects piece 76a～76d, and the direction that can intersect along the moving direction with first to fourth movable block 74a～74d is freely mobile; And first to fourth fixed cell 77a～77d, having relative end, these relative ends are fixed to respectively first to fourth and intersect the end face of piece 76a～76d and the bottom surface of workbench 50.
First to fourth motor 71a～71d is controlled independently by controller respectively.That is, cover the degree that roller 40 misplaces at X-axis, Y-axis and θ axle if calculate the film that is attracted on the workbench 50 by vacuum with respect to blanket, then controller can be respectively and is controlled independently first to fourth motor 71a～71d, so that workbench 50 can intersect moving of piece 76a～76d by first to fourth movable block 74a～74d and first to fourth.
Be mobile first to fourth movable block 74a～74d stably, provide a plurality of first to fourth track 75a～75d at the end face of gripper shoe 58, to be used for the movement of guiding first to fourth movable block 74a～74d.Therefore, the first to fourth movable block 74a～74d that moves along the length direction of first to fourth ball screw 72a～72d by the rotation of first to fourth ball screw 72a～72d can be stably mobile along first to fourth track 75a～75d.
As mentioned above, first to fourth movable block 74a～74d moves by the running of first to fourth motor 71a～71d.Yet opposite with first to fourth movable block 74a～74d, first to fourth intersects piece 76a～76d freely moves on first to fourth movable block 74a～74d.
For this reason, such as Fig. 8 and shown in Figure 9, a plurality of protuberance 78a and shifting axle 59 are provided, these outstanding 78a project upwards and form one with through hole 79a from the end face of the first movable block 74a, and this shifting axle 59 is coupled to movably protuberance 78a and intersects piece 76a to pass through hole 79a and to be fixed at least partly first.By this kind configuration, first intersects piece 76a can freely move by the length direction along shifting axle 59 on the end face of the first movable block 74a.Herein, can be at the second to the 4th movable support unit 70b, 70c and 70d and this kind configuration that protuberance 78a and shifting axle 59 are provided respectively in such as Fig. 8 and the first movable support unit 70a shown in Figure 9.For simplicity, will no longer be given unnecessary details the second to the 4th movable support unit 70b, 70c and 70d.
First to fourth movable support unit 70a～70d is arranged to rectangular layout at four corner region places of gripper shoe 58, so that workbench 50 can obtain more stable support.Yet workbench 50 must move to realize along X-axis, Y-axis and θ axle the alignment operation of film where necessary, and therefore the arranged direction of first to fourth movable support unit 70a～70d is also extremely important.In this exemplary embodiment, be formed at respectively the screw rod of arranging along diagonal among first to fourth ball screw 72a～72d among first to fourth movable support unit 70a～70d and be arranged to have the identical direction of essence at the end face of gripper shoe 58, thereby workbench 50 can be moved along X-axis, Y-axis and θ axle.Further, be arranged among first to fourth motor 71a～71d among first to fourth movable support unit 70a～70d the motor arranged along diagonal toward each other.By this kind structure, can easily along X-axis, Y-axis and θ axle (referring to Figure 11 to Figure 13) mobile working platform 50, therefore can carry out alignment operation to film more efficiently.
Be attracted to by vacuum in the lip-deep state of workbench 50 at film, workbench 50 moves along the in-plane (for example X-axis (referring to Figure 11), Y-axis (referring to Figure 12) and θ axle (referring to Figure 13)) of workbench 50, so that but alignment operation is carried out to film in relative elevation degree ground, this will be described below.
For proceeding this kind alignment operation, be arranged in the front at place, relative both sides of workbench 50 and back side up/down cylinder 53a and 53b and must be arranged in workbench 50 belows, the nargin (margin) that can move along X-axis, Y-axis and θ axle with the workbench 50 that guarantees to obtain to make adsorbent thin film.
In other words, if film is attracted on the workbench 50 by vacuum, then front and back side up/down cylinder 53a and 53b running is so that the lip-deep fringe region that is not attracted to workbench 50 of film is more lax than the lip-deep zone that is attracted to workbench 50 of film.
Then, platform movement support 70 running is with along X-axis (referring to Figure 11), Y-axis (referring to Figure 12) and θ axle (referring to Figure 13) mobile working platform 50, and is so that film can align with the relative position that blanket covers between the roller 40, as described below.
