Description
The present invention relates to the screen printing apparatus of conductor printing on blank with predetermined pattern.
Figure 19 shows that existing screen printing apparatus.Figure 19 is the summary construction diagram of traditional screen printing apparatus.This screen printing apparatus has: the carrier band 102 that is formed with the band shape of ceramic blank sheet 101 in advance on the surface; Be equipped with the feed reel 103 of this carrier band 102; Be used to batch take-up reel 104 from the carrier band 102 of pulling out for roll coil of strip dish 103; For half tone 106, scraper plate 107 and the supporting station 108 of the ceramic blank sheet 101 that forms on the carrier band 102 that pulls out with screen painting electric conductivity tin cream 105; And the drying device 109 that is used to dry the electric conductivity tin cream 105 that is printed on the ceramic blank sheet 101.
This screen printing apparatus carries out following action by control device 113 controls.At first, air pump 112 makes among the air chamber 110a and acts on negative pressure, thereby by netted conveyer belt 111 carrier band 102 is attracted on the supporting station 108.Thus carrier band 102 is remained on the supporting station 108.Use half tone 106 and scraper plate 107 that electric conductivity tin cream 105 is printed on the ceramic blank sheet 101 then in this state.In case printing finishes, air pump 112 is promptly removed the suction function for air chamber 110a, and acts on some malleations a little and remove the absorption of carrier band 102 at supporting station 108.Rotate take-up reel 104 and feed reel 103 then so that carrier band 102 moves preset distance.At this moment, for preventing carrier band 102 damage, make conveyer belt 111 in the moving of carrier band 102, be rotated mobile along this moving direction.By carrying out above action continuously, promptly at the surface printing electric conductivity tin cream 105 of ceramic blank sheet 101.
On the other hand, carrier band 102 is before being winding to take-up reel 104, earlier by drying device 109 inside.In this drying device 109, the electric conductivity tin cream 105 that is printed on the ceramic blank sheet 101 is dried.
Yet this screen printing apparatus can not fully be guaranteed the durability of conveyer belt 111, therefore has the problem that must change the operation of conveyer belt 111 continually.It is former because conveyer belt 111 moves with 102 rotations of carrier band.But, can't solve problem by the material that changes conveyer belt 111 because conveyer belt 111 must have gas permeability.
The present invention in view of this, its purpose is to provide a kind of durability high and can reduce the screen printing apparatus of maintenance frequency.
For realizing above purpose, the screen printing apparatus of the present invention's first technical scheme, upload at supporting station and to be placed with the carrier band that the surface is formed with blank, the conductor of screen painting predetermined pattern on above-mentioned blank, it is characterized in that: the surface of above-mentioned supporting station is formed by porous plastid, and has the attraction mechanism that the carrier band is attracted to the supporting station direction through this porous plastid.
According to the present invention, the supporting station surface is formed by porous plastid, can utilize attraction mechanism through this porous plastid the carrier band to be attracted to the supporting station surface and also be kept.Herein, because of the supporting station surface system that contacts with the carrier band is formed by porous plastid, so durability is very high.
Again, the screen printing apparatus of the present invention's second technical scheme, be in the screen printing apparatus of technical scheme 1, it is characterized in that: be formed with an air chamber in the inboard of above-mentioned supporting station, the wall of at least one part of this air chamber is made of above-mentioned porous plastid, and above-mentioned attraction mechanism attracts the air in this air chamber.
According to the present invention, constitute by above-mentioned porous plastid because be formed on the wall of at least one part of air chamber of the inboard of above-mentioned supporting station, therefore, during air in attracting this air chamber, can make the attraction on porous plastid surface be tending towards even.So can not realize stable attraction and maintenance because of the inhomogeneous skew of carrier band or the wrinkling that causes that produce of attraction.
Again, the screen printing apparatus of the present invention's the 3rd technical scheme is in the screen printing apparatus of technical scheme 2, it is characterized in that: be provided with the stiffener that prevents the porous plastid distortion in the air chamber of above-mentioned supporting station.
According to the present invention, even, also can produce distortion because of stiffener prevents it in that pressure is added under the situation of porous plastid by attracting mechanism to make air chamber become negative pressure.Therefore, the supporting station surface can be remained stable face, so the carrier band can not be offset or produce wrinkling.Especially, when strengthening printing area for boosting productivity, through regular meeting because the distortion of porous plastid causes printing precision to worsen too greatly and easily, but in the present invention then owing to be provided with stiffener, so can prevent the deterioration of this printing precision.In addition, owing to used stiffener, can adopt the multiple different porous plastid of soft for example or slim shape.
Again, the screen printing apparatus of the present invention's the 4th technical scheme, be in technical scheme 2 or 3, in each the screen printing apparatus, to it is characterized in that: the air chamber of above-mentioned supporting station is divided into a plurality of little air chambers, and above-mentioned attraction mechanism can the independent separately air that attracts each little air chamber.
According to the present invention, above-mentioned air chamber is divided into a plurality of little air chambers, distributes so can arbitrarily set the attraction on porous plastid surface.Attraction as the surface of porous plastid is even, and the skew of carrier band or the wrinkling that cause because of attraction is inhomogeneous just can not take place, and can realize that this carrier brings the attraction and the maintenance of line stabilization into.
Again, the screen printing apparatus of the 5th technical scheme of the present invention, be in the screen printing apparatus of technical scheme 4, it is characterized in that: have controlling organization, it is will set that the attraction zone that makes the porous plastid surface is passed in time when beginning to attract for each stingy chamber the time difference for and the mode that enlarges is controlled above-mentioned attraction mechanism.
According to the present invention, attracting the carrier band is not to carry out simultaneously on the porous plastid surface, so when attracting the carrier band, bubble etc. can be enclosed between carrier band and the porous plastid, can not make the carrier band that skew or wrinkling take place yet, can realize this carrier is brought into the attraction and the maintenance of line stabilization.

Below in conjunction with the description of drawings embodiments of the invention.
(first example)
The screen printing apparatus of first example of the present invention at first, is described with Fig. 1 and Fig. 2.
This screen printing apparatus is the device that printing is used to form the electric conductivity tin cream of the internal electrode of these lamination-type parts etc. and conductive pattern above the ceramic blank sheet used in the manufacture process of for example laminated ceramic capacitor, laminate-type ceramic inductor, ceramic multilayer circuit board etc.
As shown in Figure 1, this screen printing apparatus has: the carrier band 2 that is formed with the band shape of blank 1 in advance on the surface; Be equipped with the feed reel 3 of this carrier band 2; Be used to batch take-up reel 4 from the carrier band 2 of pulling out for roll coil of strip dish 3.It is main component that carrier band 2 adopts with for example PETG (PET).Ceramic blank sheet 1 is pre-formed on carrier band 2 by wing (doctor blade) method etc.
Between feed reel 3 and take-up reel 4, dispose half tone 6, scraper plate 7 and the supporting station 8 on the surface that electric conductivity tin cream 5 can be printed on the ceramic blank sheet 1 that moves to take-up reel 4 from feed reel 3.And, dispose the drying device 9 that is used to dry the electric conductivity tin cream 5 that is printed on the ceramic blank sheet 1 in take-up reel 4 sides of half tone 6.
Supporting station 8 is configured in and is separated with carrier band 2 and the position relative with half tone 6, and being used for becomes the plane with 2 supportings of carrier band when the screen painting for making ceramic blank sheet 1.
Supporting station 8 has: the top box-like supporting station body 10 that is opening; And the flat porous scutum 11 that is used to seal the top opening of supporting station body 10.The circumference of porous scutum 11 is supported on the step-like support 10a on the internal face of supporting station body 10.The upper surface of the upper surface of porous scutum 11 and supporting station body 10 remains on same plane.Has an air chamber 12 that constitutes by this supporting station body 10 and porous scutum 11 in the inboard of supporting station 8.That is to say that the some of the wall of air chamber 12 is made of porous scutum 11.
Above-mentioned porous scutum 11 by ceramic sintered bodies (for example: the porous member with gas permeability of zirconium sintering metal body etc.) constitute, and for example adopt that the porosity is 60～80%, hole diameter is the porous member of 10～200 μ m.In addition, even the surface of porous scutum 11 preferably adopts carrier band 2 to wipe the smooth surface of the low-friction coefficient that moving porous scutum 11 and carrier band 2 both sides can not damage in the above.
Be formed with ventilation mouth 10b in the bottom surface of supporting station body 10.Ventilation mouth 10b connects air pump 14 through pipeline 13.This air pump 14 is controlled driving by control device 15, can be for air chamber 12 effect malleation and negative pressure.Therefore, when driving air pump 14 for air chamber 12 effect negative pressure, carrier band 2 promptly through porous scutum 11 be adsorbed to porous scutum 11 above direction and be maintained at the upper surface of this porous scutum 11.In addition, as removing the negative pressure that acts on air chamber 12 in this state, then can remove the effect that carrier band 2 is drawn to porous scutum 11.In addition, if, then carrier band 2 is drawn to the effect of porous scutum 11, also can between carrier band 2 and porous scutum 11, form some spaces a little except that removing energetically to air chamber 12 effect malleations.
This screen printing apparatus carries out following action by the control of control device 15.At first, air pump 14 is for air chamber 12 effect negative pressure, so that carrier band 2 is attracted on the supporting station 8 across porous scutum 11.Like this, carrier band 2 just is fixed on supporting station 8.Then, in this state, use half tone 6 and scraper plate 7 that electric conductivity tin cream 5 is printed onto on the ceramic blank sheet 1.In case printing finishes, air pump 14 is promptly removed the negative pressure that acts on air chamber 12, and acts on some malleations a little.Remove the absorption of carrier band 2 on supporting station 8 thus, and between supporting station 8 and carrier band 2, produce some spaces.Rotate take-up reel 4 and feed reel 3 then, make carrier band 2 move predetermined distance.In the moving process of this carrier band 2, keep positive pressure for air chamber 12 always.By carrying out above action continuously, the electric conductivity tin cream 5 of predetermined pattern can be drawn the surface of brush at ceramic blank sheet 1.
On the other hand, carrier band 2 passes through drying device 9 earlier before being winding to take-up reel 4.In this drying device 9, the electric conductivity tin cream 5 that is printed on the ceramic blank sheet 1 is dried.
The screen printing apparatus of this example is made of porous scutum 11 because of the upper surface of supporting station 8, has higher durability so compare with the device of the traditional netted conveyer belt of use.Therefore, can reduce the maintenance frequency of supporting station, and then improve convenience.
(second example)
Below by Fig. 3 the screen printing apparatus of second example of the present invention is described.
The difference of the screen printing apparatus of this example and first example is the structure of supporting station, and the structure of other parts is then identical.Therefore, below only be directed to supporting station structure describe, the explanation of other structure division then is omitted.
The supporting station 20 of this example has: the top box-like supporting station body 21 that is opening; Be used to seal the flat porous scutum 22 of the top opening of supporting station body 21; And be used to prevent that porous scutum 21 from producing the stiffener 23 of distortion.
Stiffener 23 by at least than the higher material of the rigidity of porous scutum 22 for example iron plate etc. constitute.In this stiffener 23, also be formed with a plurality of air-vent 23a.Internal face at supporting station body 21 is provided with stage portion and forms support 21a, with the circumference of supporting stiffener 23.Porous scutum 22 is overlapping and be configured on the stiffener 23.The upper surface of the upper surface of porous scutum 22 and supporting station body 21 is held in same plane.Be formed with an air chamber 24 that forms by this supporting station body 21 and porous scutum 22 and stiffener 23 in the inboard of supporting station 8.That is to say that the some of the wall of air chamber 24 is made up of the porous scutum 23 that the air-vent 23a from stiffener 23 exposes.In addition, the material of porous scutum 22 is identical with the material of first example.
On the bottom surface of supporting station body 21, be formed with ventilation mouth 21b.Ventilation mouth 21b is connected to air pump (diagram is omitted) through pipeline (diagram is omitted).This air pump is controlled driving by control device (diagram is omitted), and can be for air chamber 24 effect negative pressure and malleations.Thus, when driving air pump for air chamber 24 effect negative pressure, the carrier band that is positioned at the top of porous scutum 22 promptly attracted to porous scutum 22 upper surface direction and remain on the upper surface of this porous scutum 22.If remove the negative pressure that acts on air chamber 24 in this state, just can remove the effect that porous scutum 22 attracts the carrier band again.In addition, if to air chamber 24 effect malleations, then attract also can between carrier band and porous scutum 22, form some spaces a little the effect of carrier band except that removing porous scutum 22 energetically.
Therefore, in the supporting station 20 of this example, because dispose stiffener 23, so even be subjected to the deflection deformation that the brute force pushing of scraper plate also can prevent porous scutum 22 during screen painting in air chamber 24 sides of porous scutum 22.Similarly, when air chamber 24 becomes negative pressure state, also can prevent the deflection deformation of porous scutum 22.Therefore can prevent the ceramic blank sheet skew that the deflection deformation because of porous scutum 22 causes or wrinkling takes place, can carry out screen painting reliably.This is effective especially when enlarging printing area for boosting productivity.That is to say, generally speaking, along with the expansion of printing area, porous scutum 22 easily produces deflection deformation, therefore printing precision also worsens thereupon, but 20 of the supporting stations of this example are difficult for producing this deflection deformation, so also can not reduce printing precision even enlarge printing area.Effect as for other is then identical with first example.
(the 3rd example)
Below by Fig. 4 the screen printing apparatus of the 3rd example of the present invention is described.
The difference of the screen printing apparatus of this example and first example is the structure of supporting station, and the structure of other parts is then identical.Therefore, below only be directed to supporting station structure describe, the explanation of other structure division then is omitted.
The supporting station 30 of this example has: the top box-like supporting station body 31 that is opening; And the flat porous scutum 32 that is used to seal the top opening of supporting station body 31.Supporting station body 31 has: wall is provided with stage portion and the first support 31a that forms within it; With and upper surface and the first support 31a be same plane and hung into the second support 31b of leap on relative wall.The circumference of porous scutum 32 is supported on the first support 31a of supporting station body 31, and central portion is then supported by the second support 31b.The upper surface of the upper surface of porous scutum 32 and supporting station body 31 is in the same plane.Form air chamber 33 by this supporting station body 31 and porous scutum 32 in the inboard of supporting station 30.That is to say that the some of the wall of air chamber 33 is made of porous scutum 32.Again, the material of porous scutum 32 is identical with the material of first example.
On the bottom surface of supporting station body 31, be formed with ventilation mouth 31c.Ventilation mouth 31c is connected to air pump (diagram is omitted) through pipeline (diagram is omitted).This air pump is driven control by control device (diagram is omitted), and can be for air chamber 33 effect negative pressure and malleations.Thus, when driving air pump for air chamber 33 effect negative pressure, the carrier band that is positioned at the top of porous scutum 32 will attracted to porous scutum 32 upper surface direction and be maintained at the upper surface of this porous scutum 32.If remove the negative pressure that acts on air chamber 33 in this state, just can remove the effect that porous scutum 32 attracts the carrier band again.In addition, if to air chamber 33 effect malleations, then attract also can between carrier band and porous scutum 32, form some spaces a little the effect of carrier band except that removing porous scutum 32 energetically.
Therefore, in the supporting station 30 of this example, because air chamber 33 sides at porous scutum 32 are formed with the second support 31b that can be used as stiffener, the central portion that is used for supporting cellular scutum 32 is so even be subjected to the deflection deformation that the brute force pushing of scraper plate also can prevent porous scutum 32 during screen painting.Similarly, when air chamber 33 becomes negative pressure state, also can prevent the deflection deformation of porous scutum 32.Therefore can prevent the ceramic blank sheet skew that the deflection deformation because of porous scutum 32 causes or wrinkling takes place, can carry out screen painting reliably.This is effective especially when strengthening printing area for the raising productivity.That is to say, generally speaking, along with the expansion of printing area, porous scutum 32 easily produces deflection deformation, therefore printing precision is also being followed and is being worsened, but 30 of the supporting stations of this example are difficult for producing this deflection deformation, so also can not reduce printing precision even enlarge printing area.Effect as for other is then identical with first example.
(the 4th example)
Below by Fig. 5 and Fig. 6 the screen printing apparatus of the 4th example of the present invention is described.
The difference of the screen printing apparatus of this example and first example is the structure of supporting station, and the structure of other parts is then identical.Therefore, below only be directed to supporting station structure describe, the explanation of other structure division then is omitted.
The supporting station 40 of this example has: the box-like supporting station body 41 that forms the peristome of four rectangles in the above; And four flat porous scutums 42 that are used to seal each peristome of supporting station body 41.Supporting station body 41 is divided into four peristomes by cross over the inside casing 41a hang between the relative wall above inciting somebody to action.Be formed with support 41b at the internal face of the lower edge of inside casing 41a and supporting station body 41 towards the peristome inboard.Each porous scutum 42 supports circumference at each peristome place by this support 41b.The upper surface of the upper surface of porous scutum 42 and supporting station body 41 is positioned at same plane.Form an air chamber 43 by this supporting station body 41 in the inboard of supporting station 40 with porous scutum 42.That is to say that the some of the wall of air chamber 43 is made of porous scutum 42.Again, the material of porous scutum 42 is identical with the material of first example.
Be formed with ventilation mouth 41c in the bottom surface of supporting station body 41.Ventilation mouth 41c is connected to air pump (diagram is omitted) through pipeline 44.This air pump is driven control and can be acted on negative pressure and malleations to air chamber 43 by control device (diagram is omitted).Thus, when driving air pump for air chamber 43 effect negative pressure, the carrier band that is positioned at the top of porous scutum 42 will attract and be maintained at the upper surface of this porous scutum 42 towards the direction of the upper surface of porous scutum 42.If remove the negative pressure that acts on air chamber 43 in this state, just can remove the effect that porous scutum 42 attracts the carrier band again.In addition, if to air chamber 43 effect malleations then attract also can between carrier band and porous scutum 42, form some spaces a little the effect of carrier bands except that removing porous scutum 42 energetically.
In the supporting station 40 of this example, dispose four porous scutums 42 in the above.Because the area of porous scutum 42 is less than the area of first example, so can prevent the deflection deformation of porous scutum 42.Owing to can prevent the ceramic blank sheet skew that the deflection deformation because of porous scutum 42 causes or wrinkling takes place, so can carry out screen painting reliably.This is effective especially when strengthening printing area for the raising productivity.Effect as for other is then identical with first example.
(the 5th example)
Below by Fig. 7 to Fig. 9 the screen printing apparatus of the 5th example of the present invention is described.
This example and the difference of the screen printing apparatus of first example are that the structure of structure other parts of supporting station is then identical.Therefore, below only be directed to supporting station structure describe, the explanation of other structure division then is omitted.
The supporting station 50 of this example has: the box-like supporting station body 51 that forms the peristome of four rectangles in the above; And four flat porous scutums 52 that are used to seal each peristome of supporting station body 51.Supporting station body 51 is divided into four peristomes by crossing over partition wall 51a between the relative wall above inciting somebody to action.The upper surface of the upper surface of partition wall 51a and supporting station body 51 is in the same plane.On the internal face of supporting station body 51 and partition wall 51a, be provided with stage portion and form support 51b.Each porous scutum 52 supports circumference at each peristome place by this support 51b.The upper surface of the upper surface of porous scutum 52 and supporting station body 51 is in the same plane.Form four air chambers 53 in the inboard of supporting station 50 by this supporting station body 51 and partition wall 51a and porous scutum 52.That is to say that the some of the wall of air chamber 53 is made of porous scutum 52.Again, the material of porous scutum 52 is identical with the material of first example.
Bottom surface at each air chamber 53 of supporting station body 51 is formed with ventilation mouth 51c respectively.Ventilation mouth 51c is connecting pipe 54 respectively.As shown in Figure 9, each pipeline 54 connects into and trunk line 55 interflow, and is connected to air pump 56 through trunk line 55.This air pump 56 is driven control by control device 57, and can be to each air chamber 53 effect negative pressure and malleation.Thus, when driving air pump 56 for each air chamber 53 effect negative pressure, the carrier band that is positioned at porous scutum 52 tops will attracted to the direction of the upper surface of porous scutum 52, and be maintained at the upper surface of this porous scutum 52.If remove the negative pressure that acts on air chamber 53 in this state, just can remove the effect that porous scutum 52 attracts the carrier band again.In addition, if to air chamber 53 effect malleations, then attract also can between carrier band and porous scutum 52, form some spaces a little the effect of carrier band except that removing porous scutum 52 energetically.
In the supporting station 50 of this example, dispose four porous scutums 52 in the above.Because the area of porous scutum 52 is less than the area of first example, so can prevent the deflection deformation of porous scutum 52.This is effective especially when strengthening printing area for boosting productivity.Again, because form a plurality of air chambers 54 in the inboard of supporting station 50, so compare the upper surface attraction inequality that can prevent porous scutum 52 with first example.So can prevent the skew of ceramic blank sheet or wrinkling takes place, thereby can carry out screen painting reliably.Effect as for other is then identical with first example.
In addition, in this example,, also can as shown in Figure 10 each pipeline 54 be connected respectively to each air pump 56 though be that pipeline 54 is collaborated to carry out attraction work for each air chamber 53 to a trunk line 55 and by an air pump 56.In addition, also can in each pipeline 54, valve 58 be set as shown in Figure 11, utilize control device 57 to control the generation and the releasing of this valve 58 and then control attraction.In Figure 10 and example shown in Figure 11, though take place to distinguish control independently with the releasing attraction for each air chamber 53, even but in this case, the generation of this attraction can be set each air chamber 53 for and carries out simultaneously with removing, but also the setting-up time difference is carried out.

The difference of the screen printing apparatus of this example and first example is the structure and the adsorption structure of supporting station.The structure of other parts is then identical.Therefore, below only be directed to supporting station structure and adsorption structure describe, the explanation of other structure division then is omitted.
The supporting station 60 of this example has: the box-like supporting station body 61 that is opening in the above; And the flat porous scutum 62 that is used to seal the peristome of supporting station body 61.Supporting station body 61 is provided with partition wall 61a between wall in opposite directions.The upper surface of the support 61b that the upper surface of partition wall 61a forms with at the internal face of supporting station body 61 stage portion being set is positioned at same plane.The circumference of porous scutum 62 is by support 61b supporting, and central portion is then supported by partition wall 61a.The upper surface of the upper surface of porous scutum 62 and supporting station body 61 is positioned at same plane.Form four air chambers 63 separating by this supporting station body 61 and partition wall 61a and porous scutum 62 in the inboard of supporting station 60.That is to say that the some of the wall of each air chamber 63 is made of porous scutum 62.Again, the material of porous scutum 62 is identical with the material of first example.
On the bottom surface of each air chamber 63 of supporting station body 61, formed ventilation mouth 61c respectively.Ventilation mouth 61c is connecting pipe 64 respectively.Each pipeline 54 and the 5th example similarly connect into and trunk line (diagram is omitted) interflow, and are connected to air pump (diagram is omitted) through trunk line.This air pump is driven control by control device (diagram is omitted), and can be to each air chamber 63 effect negative pressure and malleation.Thus, when driving air pump for each air chamber 63 effect negative pressure, the carrier band that is positioned at porous scutum 62 tops will attracted to the direction of the upper surface of porous scutum 62, and remain on the upper surface of this porous scutum 62.If remove the negative pressure that acts on air chamber 63 in this state, just can remove the effect that porous scutum 62 attracts the carrier band again.In addition, if to air chamber 63 effect malleations, then attract also can between carrier band and porous scutum 62, form some spaces a little the effect of carrier band except that removing porous scutum 62 energetically.
Therefore, in the supporting station 60 of this example, because the central portion of porous scutum 62 is by partition wall 61a supporting, even be subjected to the deflection deformation that the brute force pushing of scraper plate also can prevent porous scutum 62 during screen painting.Similarly, when air chamber 63 becomes negative pressure state, also can prevent the deflection deformation of porous scutum 62.This is effective especially when strengthening printing area for the raising productivity.That is to say, generally speaking, along with the expansion of printing area, porous scutum 62 easily produces deflection deformation, therefore printing precision also worsens thereupon, but 60 of the supporting stations of this example are difficult for producing this deflection deformation, so also can not reduce printing precision even enlarge printing area.In addition, be formed with a plurality of air chambers 64 in the inboard of supporting station 60, so compare the upper surface attraction inequality that can prevent porous scutum 62 with first example.So can prevent the skew of ceramic blank sheet or wrinkling takes place.So can carry out screen painting reliably.Effect as for other is then identical with first example.
In addition, in this example, though be that pipeline 64 is collaborated a trunk line, and carry out attraction of each air chamber 63 etc. by an air pump, but also can be and as shown in Figure 11 as the Figure 10 in the 5th example, valve (diagram omit) is set in each pipeline 64, controls this valve and control the generation and the releasing of attraction by control device.
(the 7th example)
Below by Figure 14 to Figure 18 the screen printing apparatus of the 7th example of the present invention is described.
This example is the structure of supporting station and the mode that control attracts with the difference of the screen printing apparatus of the 6th example.The structure of other parts is then identical.Therefore, below only be directed to the structure of supporting station and mode that control attracts describes, the explanation of other structure division then is omitted.
The main difference point of the supporting station 70 of this example and the supporting station 60 of the 6th example is the number of the inboard air chamber that forms.That is to say that supporting station 70 has: the box-like supporting station body 71 that is opening in the above; And the flat porous scutum (Figure 14 illustrates omission) that is used for sealing the peristome of supporting station body 71.Between the relative wall of supporting station body 71, be provided with a plurality of partition wall 71a.The upper surface of the support (diagram is omitted) that the upper surface of partition wall 71a forms with at the internal face of supporting station body 71 stage portion being set is positioned at same plane.The circumference of porous scutum 72 is by support part supports, and central portion is then supported by partition wall 71a.The upper surface of the upper surface of porous scutum 72 and supporting station body 71 is positioned at same plane.Form a plurality of (having 81 among Figure 14) air chamber 73 that is separated into by this supporting station body 71 and partition wall 71a and porous scutum 72 in the inboard of supporting station 70.That is to say that the some of the wall of each air chamber 73 is made of porous scutum 72.Again, the material of porous scutum 72 is identical with the material of first example.
On the bottom surface of each air chamber 73 of supporting station body 71, be formed with ventilation mouth 71c respectively.Ventilation mouth 71c is connecting pipe (diagram is omitted) respectively.Similarly being connected to of the illustrated mistake of Figure 11 of each pipeline and the 5th example through valve (diagram is omitted) and trunk line (diagram is omitted) interflow, and be connected to air pump (diagram is omitted) through Trunk Line.This air pump and each valve are driven control by control device (diagram is omitted), and can be for each air chamber 73 effect negative pressure and malleation.Thus, when driving air pump for each air chamber 73 effect negative pressure, the carrier band that is positioned at the top of porous scutum will attracted to the direction of the upper surface of porous scutum, and be maintained at the upper surface of this porous scutum.If remove the negative pressure that acts on air chamber 73 in this state, just can remove the effect that the porous scutum attracts the carrier band again.In addition, if, then except that the effect that can remove porous scutum attraction carrier band energetically, also can between carrier band and porous scutum 72, form some spaces a little to air chamber 73 effect malleations.
Below describe the action when attracting the carrier band in detail.In this example, when attracting carrier band 74 like that shown in Figure 15～18, the top attraction zone of porous scutum 72 is controlled to passing in time and increases.In addition, region representation shown in Figure 15～18 bends is subjected to the zone that suction function attracts because of the driving of air pump.
For example in Figure 15, the valve corresponding with the pipeline that is connected in each air chamber 73 is controlled to the direct of travel in the past direction rear increase of attraction zone with respect to carrier band 74.In addition, in Figure 16, valve that will be corresponding with the pipeline that is connected in each air chamber 73 is controlled to the direction increase that attracts the zone to intersect vertically to the direct of travel with carrier band 74.In addition, in Figure 17, will the valve corresponding be controlled to and attract the zone irrelevant, but the mind-set circumference increases from porous scutum 72 with the direct of travel of carrier band 74 with the pipeline that is connected in each air chamber 73.In addition, in Figure 18, will the valve corresponding be controlled to and attract the zone to increase to oblique rear from front ends with respect to the direct of travel of carrier band 74 with the pipeline that is connected in each air chamber 73.
The supporting station 70 of this example is when attracting carrier band 74, owing to be that porous scutum 72 top attraction zones are controlled to pass in time and enlarge, so bubble can not be closed between carrier band 74 and the porous scutum 72.So can prevent the skew or the wrinkling of carrier band 74, thereby can carry out screen painting reliably.Then identical as for other effect with the 6th example.
By above specifying as can be known, according to the present invention because the supporting station surface is to form with porous plastid, thus can utilize attract mechanism and through this porous plastid with the absorption of carrier band and remain on the supporting station surface.Owing to form by porous plastid with the contacted supporting station of carrier band surface, so durability is very high.Thereby can reduce the maintenance frequency and the frequency of supporting station, can improve convenience.
