The ink 68 is softened by the solvent and is easily adhered by the adhesion roller 916.
去除部90具有被固定於基座50之汽缸94。汽缸94具有進行上下移動之銷95。於銷95固定有上下部97，上下部97藉由銷95之上下移動而進行上下移動，其結果，刮取式刮漿板91、黏著滾輪部910及溶劑滾輪部920會上下移動。The removal part 90 has a cylinder 94 fixed to the base 50. The cylinder 94 has a pin 95 that moves up and down. The upper and lower parts 97 are fixed to the pins 95, and the upper and lower parts 97 move up and down by the up and down movement of the pins 95. As a result, the scraping squeegee 91, the adhesive roller part 910 and the solvent roller part 920 move up and down.
＜＜熱風供給部300＞＞
利用圖1、圖2、及圖18，對熱風供給部300進行說明。熱風供給部300如圖1與圖2所示般，被配置於印刷部60與工件搭載部30之下。熱風供給部300被固定於基座50。熱風供給部300具有熱風器301、導管302、熱風吹出器303、及上下銷304與上下汽缸305。熱風器301具有加熱器及送風機，而生成熱風306。導管302係運送熱風306之送風管。熱風吹出器303係對環狀皮帶41吹出熱風306之器具。＜＜The hot air supply part 300＞＞
The hot air supply unit 300 will be described with reference to FIGS. 1, 2, and 18. The hot air supply unit 300 is arranged under the printing unit 60 and the workpiece mounting unit 30 as shown in FIGS. 1 and 2. The hot air supply unit 300 is fixed to the base 50. The hot air supply unit 300 includes a hot air heater 301, a duct 302, a hot air blower 303, upper and lower pins 304 and upper and lower cylinders 305.

As shown in Fig. 19(a), the hot air blower 303 is composed of a hollow pipe in the shape of a square formed by a plurality of rows and a plurality of columns. As shown in Fig. 19(b), the hot air blower 303 may also be a hollow box shape.
上下汽缸305被固定於基座50。上下銷304可上下移動地被安裝於上下汽缸305。上下銷304之上部被固定於熱風吹出器303之下端。控制部110藉由控制上下汽缸305使上下銷304上下移動，而使熱風吹出器303上下地移動。控制部110以於移動平台150之旋轉時不會妨礙旋轉之方式，使熱風吹出器303向下移動。控制部110於進行印刷時，使熱風吹出器303向上移動。控制部110於進行印刷時，自熱風吹出器303將熱風吹抵於環狀皮帶41之下表面，而於環狀皮帶41之下表面存在有油墨68之情形時，加熱油墨68而防止油墨68固化之情形。由於油墨68藉由熱風供給部300而不會固化，因此去除部90可容易地將油墨68去除。The upper and lower cylinders 305 are fixed to the base 50. The up and down pins 304 are mounted on the up and down cylinders 305 so as to be movable up and down.

The control unit 110 moves the hot air blower 303 downward in a manner that does not hinder the rotation when the mobile platform 150 rotates. The control unit 110 moves the hot air blower 303 upward when printing. When the control unit 110 performs printing, the hot air blower 303 blows the hot air against the lower surface of the endless belt 41, and when there is ink 68 on the lower surface of the endless belt 41, it heats the ink 68 to prevent the ink 68. The situation of curing. Since the ink 68 is not cured by the hot air supply part 300, the removing part 90 can easily remove the ink 68.

＜＜抽氣部55＞＞
利用圖5，對抽氣部55之構成進行說明。抽氣部55具有複數個抽氣溝57及複數個按壓面59。複數個抽氣溝57與複數個按壓面59交替地且平行地被配置。抽氣溝57係沿著左右方向延伸的溝，且與抽氣管56連通。抽氣溝57被形成於沿著左右方向所排列之貫通孔48的正下方。按壓面59係與環狀皮帶41之內表面接觸之平面。抽氣溝57之左右方向之長度較工件69之左右方向之長度短。位在複數個抽氣溝57之前後方向之兩端之2條抽氣溝57的距離，較工件69之前後方向之長度短。亦即，抽氣溝57存在於工件69之外形之內側，且抽氣溝57不會自工件69之外側突出。＜＜Exhaust part 55＞＞
5, the structure of the suction part 55 is demonstrated. The suction part 55 has a plurality of suction grooves 57 and a plurality of pressing surfaces 59. The plurality of suction grooves 57 and the plurality of pressing surfaces 59 are arranged alternately and in parallel.

The pressing surface 59 is a flat surface in contact with the inner surface of the endless belt 41. The length of the suction groove 57 in the left-right direction is shorter than the length of the workpiece 69 in the left-right direction. The distance between the two air extraction grooves 57 located at the two ends of the air extraction groove 57 in the front and back direction is shorter than the length of the workpiece 69 in the front and back direction. That is, the suction groove 57 exists inside the outer shape of the workpiece 69, and the suction groove 57 does not protrude from the outer side of the workpiece 69.
***動作之說明***
使用圖6，對網版印刷裝置100之網版印刷方法進行說明。又，對於步驟S15至S18中皮帶驅動裝置200之皮帶驅動方法進行說明。***Description of action***
Using FIG. 6, the screen printing method of the screen printing apparatus 100 will be described. In addition, the belt driving method of the belt driving device 200 in steps S15 to S18 will be described.
以下之動作係藉由被設置於網版印刷裝置100之控制部110所執行。再者，於網版印刷裝置100存在有2個皮帶移動機構40，圖6之左側係1個皮帶移動機構40之動作，圖6之右側係另1個皮帶移動機構40之動作。2個皮帶移動機構40之動作相同，僅動作時期會錯開。首先，對第1工件搭載部30之情形即圖6之左側之1個皮帶移動機構40之情形進行說明。The following operations are executed by the control unit 110 provided in the screen printing apparatus 100. Furthermore, there are two belt moving mechanisms 40 in the screen printing apparatus 100. The left side of FIG. 6 shows the operation of one belt moving mechanism 40, and the right side of FIG. 6 shows the operation of another belt moving mechanism 40. The actions of the two belt moving mechanisms 40 are the same, and only the action time will be staggered. First, the state of the first work mounting portion 30, that is, the state of the one belt moving mechanism 40 on the left side of FIG. 6 will be described.
首先，於電源接通之時間點，控制部110藉由位置移動部180使驅動部170成為下降之狀態，使去除部90成為下降之狀態，並使印刷刮漿板62向前方向移動，而將印刷刮漿板62定位於印刷開始位置。於電源接通之時間點，第1記憶體與第2記憶體之位置偏移量為0。First, at the time when the power is turned on, the control unit 110 uses the position moving unit 180 to lower the driving unit 170, to lower the removal unit 90, and to move the printing squeegee 62 in the forward direction. The printing squeegee 62 is positioned at the printing start position. At the time when the power is turned on, the positional offset between the first memory and the second memory is 0.
步驟S11a：工件設置步驟、抽氣開始步驟
藉由未圖示之工件搬入機構，將工件69載置於位在第1工件搭載部30之環狀皮帶41。工件69如圖2所示般自左朝右被搬入。工件69之位置被預先決定，工件69藉由工件搬入機構而相對於環狀皮帶41準確地被定位而被載置。控制部110藉由抽氣器96開始進行抽氣部55之抽氣。抽氣部55由於自被配置於抽氣溝57之貫通孔48對空氣進行抽氣，因此工件69密接於環狀皮帶41之外表面，被載置於環狀皮帶41之工件69可不會位置偏移地被固定於環狀皮帶41。由於在抽氣部55存在有密接於環狀皮帶41之內表面之按壓面59，因此環狀皮帶41不會因抽氣而向下方變形。Step S11a: Workpiece setting step, air extraction start step
The workpiece 69 is placed on the endless belt 41 of the first workpiece carrying portion 30 by a workpiece carrying mechanism (not shown). The work 69 is carried in from left to right as shown in FIG. 2. The position of the work 69 is determined in advance, and the work 69 is accurately positioned with respect to the endless belt 41 by the work carrying mechanism and placed on it. The control unit 110 starts the air extraction of the air extraction unit 55 through the air extractor 96. Since the air suction part 55 sucks air from the through hole 48 arranged in the air suction groove 57, the workpiece 69 is in close contact with the outer surface of the endless belt 41, and the workpiece 69 placed on the endless belt 41 may not be positioned. It is fixed to the endless belt 41 in an offset manner. Since there is a pressing surface 59 in close contact with the inner surface of the endless belt 41 in the suction portion 55, the endless belt 41 is not deformed downward due to suction.
步驟S12：平台旋轉步驟(正旋轉)、版框位置調整步驟
於時刻T1，控制部110使移動平台150正旋轉180度。由於皮帶移動機構40與抽氣部55會一起旋轉，因此工件69密接於環狀皮帶41之外表面，而不會有因旋轉而位置偏移之情形。Step S12: platform rotation step (positive rotation), plate frame position adjustment step
At time T1, the control unit 110 rotates the mobile platform 150 forward by 180 degrees. Since the belt moving mechanism 40 and the air suction part 55 rotate together, the workpiece 69 is in close contact with the outer surface of the endless belt 41 without position shift due to rotation.
於時刻T1，控制部110藉由儲存於第1記憶體之位置偏移量使版框位置調整部65動作。控制部110將儲存於第1記憶體之X軸方向(左右方向)與Y軸方向(前後方向)之位置偏移量之值之正負未經加工所得到的值，發送至版框位置調整部65。控制部110將儲存於第1記憶體之X軸方向與Y軸方向之位置偏移量之值之正負未經加工所得到的值發送至版框位置調整部65，其理由在於：印刷位置與拍攝位置位在以平台軸156為中心旋轉180度之對稱的位置。例如，控制部110在位置偏移量沿著X軸方向(例如左)有+1 mm之情形時，指示網版製版63之位置沿著X軸方向(例如左)偏移+1 mm。控制部110在位置偏移量沿著Y軸方向(例如前)有+1 mm之情形時，指示網版製版63之位置沿著Y軸方向(例如前)偏移+1 mm。控制部110將反轉儲存於第1記憶體之θ軸方向(旋轉方向)之位置偏移量之值之正負所得到的值，發送至版框位置調整部65。控制部110在位置偏移量在θ軸方向上為+1度之情形時，指示網版製版63之位置朝軸方向旋轉-1度。At time T1, the control unit 110 operates the frame position adjustment unit 65 by the position shift amount stored in the first memory. The control unit 110 sends the positive and negative values of the positional offset values in the X-axis direction (left-right direction) and the Y-axis direction (front-rear direction) stored in the first memory to the frame position adjustment unit. 65. The control unit 110 sends the positive and negative unprocessed values of the positional offset values in the X-axis direction and the Y-axis direction stored in the first memory to the frame position adjustment unit 65. The reason is that the printing position and The shooting position is a symmetrical position rotated by 180 degrees with the platform axis 156 as the center. For example, when the position shift amount is +1 mm along the X-axis direction (for example, the left), the control unit 110 instructs the position of the screen plate making 63 to shift along the X-axis direction (for example, the left) by +1 mm. When the position shift amount is +1 mm along the Y-axis direction (for example, the front), the control unit 110 instructs the position of the screen plate making 63 to shift along the Y-axis direction (for example, the front) by +1 mm. The control unit 110 sends the value obtained by reversing the positive and negative values of the positional offset in the θ-axis direction (rotation direction) stored in the first memory to the frame position adjustment unit 65. When the positional deviation amount is +1 degree in the θ axis direction, the control unit 110 instructs the position of the screen plate making 63 to rotate -1 degree in the axis direction.
步驟S13a：印刷步驟、熱風供給步驟
若移動平台150將工件69運來，控制部110便會於時刻T1，使上下柱51下降，並藉由印刷部60進行印刷。控制部110使印刷刮漿板62，一邊自前朝後移動一邊進行印刷。控制部110使印刷刮漿板62自印刷開始位置移動至印刷結束位置。控制部110使印刷刮漿板62，一邊自以平台軸156為中心之半徑方向之內側朝外側移動一邊進行印刷。控制部110使印刷刮漿板62，一邊朝與移動平台150之旋轉方向正交之方向移動一邊進行印刷。控制部110使印刷刮漿板62，一邊朝與移動平台150之外周圓之切線正交之方向移動一邊進行印刷。由於印刷刮漿板62朝半徑方向移動，因此印刷刮漿板62之移動不會對移動平台150施加使其旋轉之力。亦即，於印刷過程中移動平台150不會旋轉。由於藉由沿著半徑方向進行印刷不會對平台軸施加旋轉力，因此可提高印刷精度。由於自半徑方向之內側開始印刷，因此相較於自半徑方向之外側開始印刷，印刷開始時使平台軸156傾斜之力的力矩較小。環狀皮帶41之上外表面之高度由於與移動平台150之表面之高度相同，因此移動平台150不會成為印刷之阻礙。例如，印刷部60係設為進行在工件69之表面整體塗佈油墨68之所謂滿版印刷者。於進行滿版印刷之情形時，油墨68存在有會滴落於工件69之周圍之可能性。抽氣部55由於僅對工件69之背面之外周的內側進行抽氣，因此抽氣部55不會吸到滴落於工件69之周圍之油墨68。Step S13a: printing step, hot air supply step
If the moving platform 150 transports the workpiece 69, the control unit 110 will lower the upper and lower columns 51 at the time T1, and the printing unit 60 will perform printing. The control unit 110 causes the printing squeegee 62 to perform printing while moving from front to back. The control unit 110 moves the printing squeegee 62 from the printing start position to the printing end position. The control unit 110 causes the printing squeegee 62 to perform printing while moving from the inner side in the radial direction with the table shaft 156 as the center to the outer side. The control unit 110 causes the printing squeegee 62 to move in a direction orthogonal to the rotation direction of the moving platform 150 while printing. The control unit 110 causes the printing squeegee 62 to move in a direction orthogonal to the tangent to the outer circumference of the moving platform 150 while printing. Since the printing squeegee 62 moves in the radial direction, the movement of the printing squeegee 62 does not apply force to the moving platform 150 to rotate it. That is, the mobile platform 150 will not rotate during the printing process. Since printing along the radial direction does not apply rotational force to the table shaft, printing accuracy can be improved. Since printing is started from the inner side in the radial direction, the moment of the force that tilts the table shaft 156 at the start of printing is smaller than when printing is started from the outer side in the radial direction. Since the height of the upper outer surface of the endless belt 41 is the same as the height of the surface of the mobile platform 150, the mobile platform 150 will not become an obstacle to printing. For example, the printing section 60 is one that performs so-called full-page printing in which the ink 68 is applied to the entire surface of the workpiece 69. In the case of full-page printing, the ink 68 may drip around the workpiece 69. Since the suction part 55 only sucks the inner side of the outer periphery of the back surface of the work 69, the suction part 55 does not suck the ink 68 dripping around the work 69.
若移動平台150將工件69運來，於時刻T2，控制部110便會將來自熱風器301之熱風306供給至導管302，使熱風吹出器303上升，而印刷中吹出熱風。若印刷結束，控制部110便使上下柱51上升，而使印刷部60上升。又，控制部110使熱風之供給停止，並使熱風吹出器303下降。If the moving platform 150 transports the workpiece 69, at time T2, the control unit 110 will supply the hot air 306 from the hot air device 301 to the duct 302, so that the hot air blower 303 will rise, and the hot air will be blown out during printing. When the printing is finished, the control unit 110 raises the upper and lower columns 51 and raises the printing unit 60. In addition, the control unit 110 stops the supply of hot air, and lowers the hot air blower 303.
步驟S19a：刮漿板移動
控制部110在使印刷部60上升之後，將印刷刮漿板62自印刷結束位置移動至印刷開始位置。亦即，控制部110使印刷刮漿板62自後朝前移動而將印刷刮漿板62定位於印刷開始位置。Step S19a: Move the squeegee
After the control unit 110 raises the printing unit 60, it moves the printing squeegee 62 from the printing end position to the printing start position. That is, the control unit 110 moves the printing squeegee 62 from back to front to position the printing squeegee 62 at the printing start position.
步驟S14：平台旋轉步驟(逆旋轉)、版框位置調整步驟
於時刻T3，控制部110使移動平台150逆旋轉180度。控制部110藉由儲存於第2記憶體之位置偏移量，使用與在步驟S12所述之版框位置調整步驟相同的值來使版框位置調整部65動作。使第1工件搭載部30與第1記憶體之位置偏移量對應，並使第2工件搭載部30與第2記憶體之位置偏移量對應，其理由在於：考慮到存在有基於正旋轉之定位與基於逆旋轉之定位之定位誤差間有差異存在的可能性。亦即，控制部110由於基於正旋轉定位之印刷之位置調整係使用正旋轉定位之位置偏移量，而基於逆旋轉定位之印刷之位置調整係使用逆旋轉定位之位置偏移量，因此可忽視正旋轉與逆旋轉之定位誤差。Step S14: platform rotation step (reverse rotation), plate frame position adjustment step
At time T3, the control unit 110 reversely rotates the mobile platform 150 by 180 degrees. The control unit 110 uses the same value as the plate frame position adjustment step described in step S12 to operate the plate frame position adjustment unit 65 by using the position shift amount stored in the second memory. The reason for making the first work mounting part 30 correspond to the positional offset of the first memory and the second work mounting part 30 to the second memory corresponds to the positional offset is: There is a possibility that there is a difference between the positioning error of the positioning and the positioning based on the reverse rotation. That is, since the position adjustment of printing based on forward rotation positioning uses the position offset of forward rotation positioning, and the position adjustment of printing based on reverse rotation positioning uses the position offset of reverse rotation positioning, the control unit 110 can Ignore the positioning error of forward rotation and reverse rotation.
步驟S15a：拍攝步驟、皮帶循環開始步驟
於時刻T4，控制部110藉由相機66來拍攝第1工件搭載部30之工件69。控制部110根據第1工件搭載部30之工件69之圖像來計算位置偏移量，並將位置偏移量儲存於第1記憶體。於拍攝後，控制部110以如下方式開始環狀皮帶41之循環。控制部110開始馬達71之逆時針之旋轉，而將上下汽缸81之上下銷82向上推。藉由上下銷82之上升，移動座77以旋轉軸85為中心朝逆時針方向旋轉。若移動座77朝逆時針方向旋轉，驅動滾輪73之外周便與傳遞滾輪46之外周接觸。如此一來，控制部110便將皮帶移動機構40與驅動機構70加以連結。此處，所謂連結係指驅動滾輪73之外周與傳遞滾輪46之外周接觸，且驅動滾輪73之旋轉引起傳遞滾輪46之旋轉的狀態。Step S15a: shooting step, belt loop start step
At time T4, the control unit 110 uses the camera 66 to photograph the workpiece 69 of the first workpiece mounting unit 30. The control unit 110 calculates the positional deviation amount based on the image of the workpiece 69 of the first workpiece mounting unit 30, and stores the positional deviation amount in the first memory. After shooting, the control unit 110 starts the loop of the endless belt 41 in the following manner. The control unit 110 starts the counterclockwise rotation of the motor 71 and pushes the upper and lower pins 82 of the upper and lower cylinders 81 upward. As the upper and lower pins 82 rise, the moving base 77 rotates counterclockwise with the rotation shaft 85 as the center. When the moving base 77 rotates in the counterclockwise direction, the outer circumference of the driving roller 73 comes into contact with the outer circumference of the transmission roller 46. In this way, the control unit 110 connects the belt moving mechanism 40 and the driving mechanism 70. Here, the term “connection” refers to a state in which the outer circumference of the driving roller 73 is in contact with the outer circumference of the transmission roller 46, and the rotation of the driving roller 73 causes the rotation of the transmission roller 46.
馬達71之逆時針方向之旋轉係使滑輪72旋轉，而滑輪72之旋轉係經由傳遞皮帶76使滑輪74旋轉。藉由滑輪74之旋轉，驅動滾輪73朝逆時針方向旋轉。驅動滾輪73之逆時針方向之旋轉係使傳遞滾輪46旋轉，而傳遞滾輪46之旋轉係使滑輪47旋轉。滑輪47之旋轉係經由傳遞皮帶49使滑輪44旋轉。藉由滑輪44之旋轉，皮帶滾輪42朝順時針方向旋轉。藉由皮帶滾輪42之旋轉，環狀皮帶41朝順時針方向循環。若馬達71朝逆時針方向旋轉，環狀皮帶41便向右移動，而將工件69朝右方向移動。The counterclockwise rotation of the motor 71 rotates the pulley 72, and the rotation of the pulley 72 rotates the pulley 74 via the transmission belt 76. By the rotation of the pulley 74, the driving roller 73 rotates in a counterclockwise direction. The counterclockwise rotation system of the driving roller 73 rotates the transmission roller 46, and the rotation system of the transmission roller 46 rotates the pulley 47. The rotation of the pulley 47 rotates the pulley 44 via the transmission belt 49. By the rotation of the pulley 44, the belt roller 42 rotates in a clockwise direction. By the rotation of the belt roller 42, the endless belt 41 circulates in the clockwise direction. If the motor 71 rotates in the counterclockwise direction, the endless belt 41 moves to the right, and the workpiece 69 is moved to the right.
步驟S16a：抽氣停止、工件搬出步驟
控制部110於工件69朝右方向被搬出為止，持續進行皮帶循環，並於工件69朝右方向被搬出之後，停止抽氣部55所進行之抽氣。於工件69之搬出後，存在有會在環狀皮帶41之表面殘留滴落於曾配置有工件69之外周部分之油墨68的可能性。Step S16a: Steps to stop air extraction and move out the workpiece
The control unit 110 continues the belt loop until the workpiece 69 is carried out in the right direction, and after the workpiece 69 is carried out in the right direction, the air extraction by the exhaust unit 55 is stopped. After the workpiece 69 is carried out, there is a possibility that the ink 68 dripping on the outer circumference of the workpiece 69 may remain on the surface of the endless belt 41.
步驟S17a：油墨去除步驟
控制部110於工件69之搬出後，進一步繼續進行皮帶循環。控制部110使汽缸94之銷95上升，而使黏著滾輪916與溶劑滾輪926接近於環狀皮帶41之下外表面，並且使刮取式刮漿板91接觸於環狀皮帶41之曲面。首先，刮取式刮漿板91刮取殘留於環狀皮帶41之表面之油墨68。溶劑滾輪926一邊對殘留於環狀皮帶41之表面的油墨68施加壓力，一邊供給溶劑。黏著滾輪916藉由黏著力將殘留於環狀皮帶41之表面之油墨68加以去除，並且取出位在貫通孔48之油墨68。Step S17a: Ink removal step
After the workpiece 69 is carried out, the control unit 110 further continues the belt loop. The control unit 110 raises the pin 95 of the cylinder 94 so that the adhesive roller 916 and the solvent roller 926 are close to the lower outer surface of the endless belt 41, and the scraper blade 91 is brought into contact with the curved surface of the endless belt 41. First, the scraping squeegee 91 scrapes the ink 68 remaining on the surface of the endless belt 41. The solvent roller 926 supplies the solvent while applying pressure to the ink 68 remaining on the surface of the endless belt 41. The adhesive roller 916 removes the ink 68 remaining on the surface of the endless belt 41 by the adhesive force, and takes out the ink 68 located in the through hole 48.
環狀皮帶41由於分別由黏著滾輪916、溶劑滾輪926、及2個支承滾輪98所夾持，因此即便對黏著滾輪916與溶劑滾輪926施加上升壓力，環狀皮帶41亦不會朝上方向變形。又，2個彈簧913之彈力相同，而將黏著滾輪916保持為水平，且黏著滾輪916相對於環狀皮帶41沿著前後方向均勻地接觸。假設在黏著滾輪916於黏著滾輪916之上升時間點無法均勻地接觸之情形時，由於黏著滾輪916亦可藉由旋轉軸912而旋轉，使左右被彈簧913上推，因此黏著滾輪916之前後方向整體可藉由上升壓力施加於黏著滾輪916，而密接於環狀皮帶41。溶劑滾輪926亦與黏著滾輪916同樣地，前後方向整體可密接於環狀皮帶41。Since the endless belt 41 is clamped by the adhesive roller 916, the solvent roller 926, and the two support rollers 98, even if the adhesive roller 916 and the solvent roller 926 are applied with upward pressure, the endless belt 41 will not deform upward. . In addition, the elastic force of the two springs 913 is the same, and the adhesive roller 916 is kept horizontal, and the adhesive roller 916 is in uniform contact with the endless belt 41 in the front-rear direction. Suppose that when the adhesive roller 916 cannot be evenly contacted at the time when the adhesive roller 916 rises, since the adhesive roller 916 can also be rotated by the rotating shaft 912, the left and right sides are pushed up by the spring 913, so the adhesive roller 916 is in front and back directions The whole body can be applied to the adhesive roller 916 by ascending pressure to be closely attached to the endless belt 41. The solvent roller 926 is also the same as the adhesive roller 916, and the entire front and rear direction can be in close contact with the endless belt 41.
步驟S18a：皮帶循環停止步驟
控制部110於去除油墨68之後，使汽缸94之銷95下降，而結束油墨去除作業。又，使上下汽缸81之上下銷82下降，解除驅動滾輪73與傳遞滾輪46之連結，而結束皮帶移動機構40之驅動。然後，設置工件69，並開始新的印刷。Step S18a: Belt loop stop step
After removing the ink 68, the control unit 110 lowers the pin 95 of the cylinder 94 to end the ink removal operation. In addition, the upper and lower pins 82 of the upper and lower cylinders 81 are lowered, the connection between the driving roller 73 and the transmission roller 46 is released, and the driving of the belt moving mechanism 40 is terminated. Then, the workpiece 69 is set, and a new printing is started.
其次，對第2工件搭載部30之情形即圖6之右側之另1個之皮帶移動機構40之情形進行說明。Next, the state of the second work mounting portion 30, that is, the state of the other belt moving mechanism 40 on the right side of FIG. 6 will be described.
步驟S19b：刮漿板移動
電源接通後，控制部110在使印刷部60上升之後，使印刷刮漿板62朝前方向移動，而將印刷刮漿板62自印刷結束位置移動至印刷開始位置。Step S19b: Move the squeegee
After the power is turned on, the control unit 110 moves the printing squeegee 62 in the forward direction after raising the printing unit 60 to move the printing squeegee 62 from the printing end position to the printing start position.
步驟S12：平台旋轉步驟(正旋轉)、版框位置調整步驟
於時刻T1，控制部110使移動平台150正旋轉180度。如前所述般，控制部110使用儲存於第1記憶體之位置偏移量來使版框位置調整部65動作。Step S12: platform rotation step (positive rotation), plate frame position adjustment step
At time T1, the control unit 110 rotates the mobile platform 150 forward by 180 degrees. As described above, the control unit 110 uses the position shift amount stored in the first memory to operate the frame position adjustment unit 65.
步驟S15b：皮帶循環開始步驟
控制部110於移動平台150之旋轉後，同時地開始工件搭載部30之工件69的搬出與印刷部60對工件69的印刷。於時刻T2，控制部110藉由相機66來拍攝第2工件搭載部30之工件69。控制部110根據第2工件搭載部30之工件69之圖像來計算位置偏移量，並將位置偏移量儲存於第2記憶體。於拍攝後，控制部110開始進行皮帶循環開始步驟。步驟S15b之皮帶循環開始步驟的動作，與步驟S15a之皮帶循環開始步驟的動作相同。Step S15b: Belt cycle start step
The control unit 110 simultaneously starts the unloading of the workpiece 69 of the workpiece loading unit 30 and the printing of the workpiece 69 by the printing unit 60 after the rotation of the moving platform 150. At time T2, the control unit 110 uses the camera 66 to photograph the workpiece 69 of the second workpiece mounting unit 30. The control unit 110 calculates the positional deviation amount based on the image of the workpiece 69 of the second workpiece mounting unit 30, and stores the positional deviation amount in the second memory. After the shooting, the control unit 110 starts the belt loop start step. The operation of the belt cycle starting step of step S15b is the same as the operation of the belt cycle starting step of step S15a.
步驟S16b：抽氣停止、工件搬出步驟
步驟S16b之抽氣停止、工件搬出步驟的動作，與步驟S16a之抽氣停止、工件搬出步驟的動作相同。Step S16b: Steps to stop air extraction and move out the workpiece
The operation of the pumping stop and workpiece unloading step in step S16b is the same as the operation of the pumping stop and workpiece unloading step in step S16a.
步驟S17b：油墨去除步驟
步驟S17b之油墨去除步驟的動作，與步驟S17a之油墨去除步驟的動作相同。Step S17b: Ink removal step
The operation of the ink removal step of step S17b is the same as the operation of the ink removal step of step S17a.
步驟S18b：皮帶循環停止步驟
步驟S18b之皮帶循環停止步驟的動作，與步驟S18a之皮帶循環停止步驟的動作相同。Step S18b: Belt loop stop step
The operation of the belt circulation stopping step in step S18b is the same as the operation of the belt circulation stopping step in step S18a.
步驟S14：平台旋轉步驟(逆旋轉)、版框位置調整步驟
於時刻T3，控制部110使移動平台150逆旋轉180度。如前所述般，控制部110藉由儲存於第2記憶體之位置偏移量，使版框位置調整部65動作。Step S14: platform rotation step (reverse rotation), plate frame position adjustment step
At time T3, the control unit 110 reversely rotates the mobile platform 150 by 180 degrees. As described above, the control unit 110 operates the frame position adjustment unit 65 by the position shift amount stored in the second memory.
步驟S13b：印刷步驟
若移動平台150將工件69運來，控制部110便於時刻T4使上下柱51下降，並藉由印刷部60進行印刷。步驟S13b之印刷步驟的動作，與步驟S13a之印刷步驟的動作相同。若移動平台150將工件69運來，控制部110便於時刻T4使熱風吹出器303上升，並供給熱風。若印刷結束，控制部110便使上下柱51上升，而使印刷部60上升。又，控制部110使熱風之供給停止，並使熱風吹出器303下降。Step S13b: Printing step
If the moving platform 150 transports the workpiece 69, the control unit 110 facilitates the lowering of the upper and lower columns 51 at the time T4, and the printing unit 60 performs printing. The operation of the printing step of step S13b is the same as the operation of the printing step of step S13a. If the mobile platform 150 transports the workpiece 69, the control unit 110 facilitates the raising of the hot air blower 303 at the time T4, and the hot air is supplied. When the printing is finished, the control unit 110 raises the upper and lower columns 51 and raises the printing unit 60. In addition, the control unit 110 stops the supply of hot air, and lowers the hot air blower 303.
步驟S19b：刮漿板移動
控制部110於使印刷部60上升之後，使印刷刮漿板62自印刷結束位置移動至印刷開始位置。亦即，控制部110使印刷刮漿板62自後向前移動而將印刷刮漿板62定位於印刷開始位置。Step S19b: Move the squeegee
After the control unit 110 raises the printing unit 60, it moves the printing squeegee 62 from the printing end position to the printing start position. That is, the control unit 110 moves the printing squeegee 62 from back to front to position the printing squeegee 62 at the printing start position.
如以上所述，控制部110使驅動滾輪73之位置進退而使驅動滾輪73接觸於傳遞滾輪46。控制部110於移動平台150未移動之情形時，將皮帶移動機構40與驅動機構70加以連結而使環狀皮帶41循環。此外，控制部110於移動平台150進行移動之情形時，進行解除皮帶移動機構40與驅動機構70之連結的控制。As described above, the control unit 110 advances and retreats the position of the drive roller 73 to bring the drive roller 73 into contact with the transmission roller 46. When the moving platform 150 is not moving, the control unit 110 connects the belt moving mechanism 40 and the driving mechanism 70 to circulate the endless belt 41. In addition, the control unit 110 performs control to release the connection between the belt moving mechanism 40 and the driving mechanism 70 when the moving platform 150 is moving.
***實施形態1之效果***
根據該實施形態，由於旋轉力藉由自半徑方向之內側朝向外側進行印刷而不會施加於平台軸，因此可提高印刷精度。根據該實施形態，由於控制部110使移動平台150正旋轉及逆旋轉並藉由印刷部60來執行印刷，因此相較於使移動平台150僅正旋轉或僅逆旋轉來進行印刷之情形，位在移動平台150之下之零件的配置會變容易。根據該實施形態，由於控制部110重複地使移動平台150正旋轉及逆旋轉，因此纜線及信號線不會捲繞。根據該實施形態，由於去除部90將油墨68加以去除，因此可使環狀皮帶41循環而進行網版印刷。由於去除部90位於環狀皮帶41之正下方，因此在將油墨68去除時，可利用油墨68之重力來將油墨68去除。根據該實施形態，由於驅動機構70、去除部90、及熱風供給部300向下移動，因此皮帶移動機構40可利用移動平台150進行旋轉移動。本實施形態之控制部110由於在移動平台150之旋轉後，同時地開始工件搭載部30之工件69的搬出與印刷部60對工件69的印刷，因此可謀求時間之縮短化。本實施形態之控制部110由於在印刷後之印刷刮漿板之移動時，開始工件搭載部30之工件69的設置，因此可謀求時間之縮短化。***Effects of implementation form 1***
According to this embodiment, since the rotational force is not applied to the table shaft by printing from the inner side to the outer side in the radial direction, the printing accuracy can be improved. According to this embodiment, since the control unit 110 rotates the mobile platform 150 forwards and backwards and performs printing by the printing unit 60, compared to the case where the mobile platform 150 is rotated only forward or reversely for printing, The disposition of the parts under the mobile platform 150 will be easier. According to this embodiment, since the control unit 110 repeatedly rotates the moving platform 150 forward and backward, the cables and signal lines are not wound. According to this embodiment, since the ink 68 is removed by the removing unit 90, the endless belt 41 can be circulated to perform screen printing. Since the removing portion 90 is located directly below the endless belt 41, when the ink 68 is removed, the gravity of the ink 68 can be used to remove the ink 68. According to this embodiment, since the driving mechanism 70, the removing part 90, and the hot air supply part 300 move downward, the belt moving mechanism 40 can be rotated using the moving platform 150. Since the control unit 110 of the present embodiment simultaneously starts the unloading of the workpiece 69 of the workpiece loading unit 30 and the printing of the workpiece 69 by the printing unit 60 after the rotation of the moving platform 150, the time can be shortened. The control unit 110 of the present embodiment starts the installation of the workpiece 69 of the workpiece loading unit 30 when the printing squeegee is moved after printing, so that the time can be shortened.
***其他構成***
工件搭載部30與皮帶移動機構40的數量並不限定為2個。移動平台150亦可具有1個、3個、4個、或5個以上之工件搭載部30與皮帶移動機構40。該實施形態亦可應用於工件搭載部30與皮帶移動機構40之數量為1個且工件搭載部30與皮帶移動機構40之位置被固定於不藉由移動平台150進行旋轉移動而是前後地直線移動之平台之情形。該實施形態亦可應用於工件搭載部30與皮帶移動機構40之數量為1個且工件搭載部30與皮帶移動機構40之位置不會移動而是被固定之情形。控制部110亦可並非使馬達71朝逆時針方向旋轉而將工件69向右搬出者，而使馬達71朝順時針方向旋轉而將工件69朝左方向搬出。載置於環狀皮帶41之工件69的數量並不限定為1個，亦可將工件69同時地載置複數個，並利用1次印刷對複數個工件69進行印刷。驅動力之傳遞並不限定於利用滑輪與皮帶之情形，亦可為利用齒輪之齒之咬合的情形。***Other components***
The number of the workpiece mounting portion 30 and the belt moving mechanism 40 is not limited to two. The moving platform 150 may also have one, three, four, or five or more workpiece loading parts 30 and a belt moving mechanism 40. This embodiment can also be applied to the number of the workpiece mounting portion 30 and the belt moving mechanism 40 is one, and the positions of the workpiece mounting portion 30 and the belt moving mechanism 40 are fixed in a straight line back and forth without being rotated by the moving platform 150. The situation of the mobile platform. This embodiment can also be applied to a situation where the number of the workpiece mounting portion 30 and the belt moving mechanism 40 is one, and the positions of the workpiece mounting portion 30 and the belt moving mechanism 40 are not moved but are fixed. Instead of rotating the motor 71 in the counterclockwise direction to carry out the workpiece 69 to the right, the control unit 110 may rotate the motor 71 in the clockwise direction to carry out the workpiece 69 in the left direction. The number of workpieces 69 placed on the endless belt 41 is not limited to one, and a plurality of workpieces 69 may be placed at the same time, and the plurality of workpieces 69 may be printed by one printing. The transmission of driving force is not limited to the use of pulleys and belts, but may also be the use of gear teeth.
去除部90亦可並非對工件69進行滿版印刷者，而是僅對工件69之外周之內部進行印刷之情形。去除部90除了環狀皮帶41之表面的油墨68以外，亦可使用於用來將環狀皮帶41之表面的異物或灰塵去除。去除部90既可不被固定於基座50，亦可被固定於移動平台150。於去除部90被固定於移動平台150之情形時，去除部90始終位於皮帶移動機構40之下部，而與移動平台150之旋轉一起，去除部90與皮帶移動機構40同時地旋轉。去除部90只要在皮帶移動機構40之下部，即可被固定於任意處。若油墨68之去除延遲，由於會存在有油墨68自環狀皮帶41掉落之可能性，因此去除部90較佳係被配置於接近工件69之排出位置的位置。The removal part 90 may not be the one that performs full-page printing on the work 69, but only the case where the inside of the outer periphery of the work 69 is printed. In addition to the ink 68 on the surface of the endless belt 41, the removing portion 90 can also be used to remove foreign matter or dust on the surface of the endless belt 41. The removal part 90 may not be fixed to the base 50 or may be fixed to the mobile platform 150. When the removing portion 90 is fixed to the moving platform 150, the removing portion 90 is always located under the belt moving mechanism 40, and together with the rotation of the moving platform 150, the removing portion 90 and the belt moving mechanism 40 rotate simultaneously. The removal part 90 can be fixed to any place as long as it is under the belt moving mechanism 40. If the removal of the ink 68 is delayed, since the ink 68 may fall from the endless belt 41, the removal portion 90 is preferably arranged at a position close to the discharge position of the workpiece 69.
實施形態2.
於實施形態2中，對與實施形態1之不同點進行說明。Implementation form 2.
In the second embodiment, the differences from the first embodiment will be described.

＜＜皮帶移動機構40＞＞
皮帶移動機構40具有前進傳遞滾輪461及後退傳遞滾輪462。前進傳遞滾輪461係傳遞使環狀皮帶41前進之驅動力的滾輪。後退傳遞滾輪462係傳遞使環狀皮帶41後退之驅動力的滾輪。前進傳遞滾輪461與後退傳遞滾輪462藉由固定具58可進行旋轉地被固定於移動平台150之固定板99。前進傳遞滾輪461於側邊具有滑輪471，藉由前進傳遞滾輪461之旋轉而使滑輪471旋轉。後退傳遞滾輪462於側邊具有滑輪472，且滑輪472藉由後退傳遞滾輪462之旋轉而旋轉。於滑輪471與滑輪44繞掛有傳遞皮帶491。於滑輪472與滑輪45繞掛有傳遞皮帶492。＜＜Belt moving mechanism 40＞＞
The belt moving mechanism 40 has a forward transmission roller 461 and a backward transmission roller 462. The forward transmission roller 461 is a roller that transmits the driving force for moving the endless belt 41 forward. The retreat transmission roller 462 is a roller that transmits the driving force that causes the endless belt 41 to retreat. The forward transfer roller 461 and the backward transfer roller 462 are rotatably fixed to the fixed plate 99 of the mobile platform 150 by the fixture 58. The forward transmission roller 461 has a pulley 471 on the side, and the pulley 471 is rotated by the rotation of the forward transmission roller 461. The backward transmission roller 462 has a pulley 472 on the side, and the pulley 472 rotates by the rotation of the backward transmission roller 462. A transmission belt 491 is hung around the pulley 471 and the pulley 44. A transmission belt 492 is wound around the pulley 472 and the pulley 45.
＜＜驅動機構70之驅動部170＞＞
驅動部170具有前進驅動滾輪731及後退驅動滾輪732。前進驅動滾輪731係產生使環狀皮帶41前進之驅動力的滾輪。後退驅動滾輪732係產生使環狀皮帶41後退之驅動力的滾輪。前進驅動滾輪731與後退驅動滾輪732可進行旋轉地被安裝於移動座77。前進驅動滾輪731將滑輪741固定於旋轉軸。後退驅動滾輪732將滑輪742固定於旋轉軸。於滑輪72、滑輪741及滑輪742繞掛有1條傳遞皮帶76。＜＜Drive unit 170 of drive mechanism 70＞＞
The driving unit 170 has a forward drive roller 731 and a backward drive roller 732. The forward driving roller 731 is a roller that generates a driving force for moving the endless belt 41 forward. The backward driving roller 732 is a roller that generates a driving force for retreating the endless belt 41. The forward driving roller 731 and the backward driving roller 732 are rotatably mounted on the moving seat 77. The forward drive roller 731 fixes the pulley 741 to the rotating shaft. The backward driving roller 732 fixes the pulley 742 to the rotating shaft. A transmission belt 76 is wound around the pulley 72, the pulley 741, and the pulley 742.
***動作之說明***
於使工件69朝右方向移動之情形時，進行與實施形態1之步驟S15之皮帶循環開始步驟相同的動作。亦即，控制部110將上下汽缸81之上下銷82上推，使移動座77朝逆時針方向旋轉，而使前進驅動滾輪731之外周接觸於前進傳遞滾輪461之外周。馬達71之逆時針方向之旋轉係使滑輪72旋轉，而滑輪72之旋轉係經由傳遞皮帶76使滑輪741旋轉。藉由滑輪741之旋轉，前進驅動滾輪731朝逆時針方向旋轉。前進驅動滾輪731之逆時針方向之旋轉係使前進傳遞滾輪461旋轉，而前進傳遞滾輪461之旋轉係使滑輪471旋轉。滑輪471之旋轉係經由傳遞皮帶491使滑輪44旋轉。藉由滑輪44之旋轉，皮帶滾輪42朝順時針方向旋轉。藉由皮帶滾輪42之旋轉，環狀皮帶41朝順時針方向循環。如此一來，若馬達71朝逆時針方向旋轉，環狀皮帶41便向右移動，而將工件69朝右方向移動。***Description of action***
When the workpiece 69 is moved in the right direction, the same operation as the belt loop start step in step S15 of the first embodiment is performed. That is, the control unit 110 pushes up the upper and lower pins 82 of the upper and lower cylinders 81 to rotate the moving base 77 in the counterclockwise direction, so that the outer circumference of the forward drive roller 731 contacts the outer circumference of the forward transmission roller 461. The counterclockwise rotation of the motor 71 rotates the pulley 72, and the rotation of the pulley 72 rotates the pulley 741 via the transmission belt 76. With the rotation of the pulley 741, the forward drive roller 731 rotates in a counterclockwise direction. The counterclockwise rotation of the forward drive roller 731 rotates the forward transmission roller 461, and the rotation of the forward transmission roller 461 rotates the pulley 471. The rotation of the pulley 471 rotates the pulley 44 via the transmission belt 491. By the rotation of the pulley 44, the belt roller 42 rotates in a clockwise direction. By the rotation of the belt roller 42, the endless belt 41 circulates in the clockwise direction. In this way, if the motor 71 rotates counterclockwise, the endless belt 41 moves to the right, and the workpiece 69 is moved to the right.
於使工件69朝左方向移動之情形時，控制部110將上下汽缸81之上下銷82下壓，使移動座77朝順時針方向旋轉，而使後退驅動滾輪732之外周接觸於後退傳遞滾輪462之外周。馬達71之順時針方向之旋轉係使滑輪72旋轉，而滑輪72之旋轉係經由傳遞皮帶76使滑輪742旋轉。藉由滑輪742之旋轉，後退驅動滾輪732朝順時針方向旋轉。
後退驅動滾輪732之順時針方向之旋轉係使後退傳遞滾輪462旋轉，而後退傳遞滾輪462之旋轉係使滑輪472旋轉。滑輪472之旋轉係經由傳遞皮帶492使滑輪45旋轉。藉由滑輪45之旋轉，皮帶滾輪43朝逆時針方向旋轉。藉由皮帶滾輪43之旋轉，環狀皮帶41朝逆時針方向循環。如此一來，若馬達71朝順時針方向旋轉，則環狀皮帶41便向右移動，而將工件69朝右方向移動。When the workpiece 69 is moved to the left, the control unit 110 presses down the upper and lower pins 82 of the upper and lower cylinders 81 to rotate the moving seat 77 in the clockwise direction, so that the outer periphery of the reverse driving roller 732 contacts the reverse transmission roller 462 Outside the week. The clockwise rotation of the motor 71 rotates the pulley 72, and the rotation of the pulley 72 rotates the pulley 742 via the transmission belt 76. With the rotation of the pulley 742, the backward driving roller 732 rotates in a clockwise direction.
The clockwise rotation system of the backward driving roller 732 rotates the backward transmission roller 462, and the rotation system of the backward transmission roller 462 rotates the pulley 472. The rotation of the pulley 472 rotates the pulley 45 via the transmission belt 492. By the rotation of the pulley 45, the belt roller 43 rotates counterclockwise. By the rotation of the belt roller 43, the endless belt 41 circulates in the counterclockwise direction. In this way, if the motor 71 rotates in the clockwise direction, the endless belt 41 moves to the right, and the workpiece 69 is moved to the right.
***實施形態2之效果***
於將環狀皮帶41向右移動之情形時，位在右邊之皮帶滾輪42拉曳環狀皮帶41。相反地，於將環狀皮帶41向左移動之情形時，由位在左邊之皮帶滾輪43拉曳。如此，由於不會將環狀皮帶41朝移動方向推壓，因此環狀皮帶41之形狀不會變形。***Effects of Implementation Mode 2***
When the endless belt 41 is moved to the right, the belt roller 42 on the right pulls the endless belt 41. Conversely, when the endless belt 41 is moved to the left, it is pulled by the belt roller 43 on the left. In this way, since the endless belt 41 will not be pushed in the moving direction, the shape of the endless belt 41 will not be deformed.
***其他構成***
於實施形態2中，亦可取代環狀皮帶41，而使用捲取型之捲料(roll material)。捲筒紙或捲筒不織布較為柔軟。於實施形態2中，由於可將捲筒材朝左右之移動方向拉曳，因此即便為柔軟之捲料，亦可不使捲料朝捲取方向與捲回方向變形地使其移動。亦即，實施形態2之皮帶亦可並非環狀皮帶，實施形態2之皮帶亦可為帶狀之長尺寸物。捲料係不循環之皮帶之一例。***Other components***
In the second embodiment, instead of the endless belt 41, a roll material of the winding type may be used. Roll paper or roll non-woven fabric is softer. In the second embodiment, since the roll material can be pulled in the moving direction of left and right, even if it is a soft roll material, it is possible to move the roll material without deforming it in the winding direction and the winding direction. In other words, the belt of the second embodiment may not be an endless belt, and the belt of the second embodiment may be a belt-shaped long article. An example of a belt that does not circulate the coil.

In the fifth embodiment, differences from the first embodiment will be described.
***構成之說明***
圖10至圖13係實施形態5之網版印刷裝置100之前視構成圖與AA線剖面圖。圖10至圖13雖與圖1至圖4對應，但不同點在於移動平台150之底板153與固定具58。於實施形態5中，移動平台150之底板153亦存在於コ字型之切缺處，於移動平台150之存在於コ字型之切口之底板153的中央，形成有使環狀皮帶41之外下表面露出之開口部154。開口部154係與皮帶移動機構40之平面形狀相同大小之矩形，環狀皮帶41之整個外下表面被露出於下方。於開口部154之兩側，於左右豎立設置有3個固定具58。如圖12、圖13所示，於一個固定具58存在有測微計158與導件159，藉由調整測微計158可使固定具58之位置沿著導件159朝左右移動，而可調整皮帶移動機構40之滾輪之旋轉軸之左右位置。又，固定具58並非被固定於移動平台150之固定板99者，而被固定於移動平台150之底板153。實施形態5之固定具58相對於各滾輪自底板153朝上方向被豎立設置。皮帶滾輪42、皮帶滾輪43、傳遞滾輪46及支承滾輪98，藉由自底板153豎立設置之固定具58可進行旋轉地被固定於移動平台150。控制部110於移動平台150移動中使刮取式刮漿板91、黏著滾輪部910及溶劑滾輪部920下降至較移動平台150之底板153之下表面更低的位置。控制部110於油墨68之去除時，使刮取式刮漿板91、黏著滾輪部910及溶劑滾輪部920上升，並通過開口部154而將油墨68加以去除。由於在底板153形成有開口部154，因此驅動機構70與實施形態1同樣地，可相對於環狀皮帶41之外下表面，進行油墨68之去除。***Description of composition***
10 to 13 are a front view of the screen printing apparatus 100 according to the fifth embodiment and a cross-sectional view along the line AA. Although FIGS. 10 to 13 correspond to FIGS. 1 to 4, the difference lies in the bottom plate 153 and the fixture 58 of the mobile platform 150. In the fifth embodiment, the bottom plate 153 of the mobile platform 150 also exists in the U-shaped cutout. In the center of the bottom plate 153 of the mobile platform 150 that exists in the U-shaped cut, there is formed a ring belt 41 outside The opening 154 exposed on the lower surface. The opening 154 is a rectangle with the same size as the plane shape of the belt moving mechanism 40, and the entire outer and lower surface of the endless belt 41 is exposed below. On both sides of the opening 154, three fixtures 58 are erected on the left and right. As shown in Figures 12 and 13, there are a micrometer 158 and a guide 159 in a fixture 58. By adjusting the micrometer 158, the position of the fixture 58 can be moved to the left and right along the guide 159. Adjust the left and right positions of the rotating shaft of the roller of the belt moving mechanism 40. Moreover, the fixture 58 is not fixed to the fixed plate 99 of the mobile platform 150 but is fixed to the bottom plate 153 of the mobile platform 150. The fixture 58 of Embodiment 5 is erected in the upward direction from the bottom plate 153 with respect to each roller. The belt roller 42, the belt roller 43, the transmission roller 46, and the support roller 98 are rotatably fixed to the moving platform 150 by a fixture 58 erected from the bottom plate 153. During the movement of the mobile platform 150, the control unit 110 lowers the scraper squeegee 91, the adhesive roller portion 910 and the solvent roller portion 920 to a lower position than the bottom surface of the bottom plate 153 of the mobile platform 150. When the ink 68 is removed, the control unit 110 raises the scraper squeegee 91, the adhesive roller portion 910, and the solvent roller portion 920, and removes the ink 68 through the opening 154. Since the opening 154 is formed in the bottom plate 153, the drive mechanism 70 can remove the ink 68 from the outer and lower surface of the endless belt 41 in the same manner as in the first embodiment.
實施形態6.
於實施形態6中，對與實施形態5之不同點進行說明。Embodiment 6.
In the sixth embodiment, differences from the fifth embodiment will be described.
***構成之說明***
圖14係實施形態6之網版印刷裝置100之構成圖。實施形態6之網版印刷裝置100係將實施形態2之皮帶移動機構40與驅動機構70之驅動部170應用於實施形態5之網版印刷裝置100者。如此，亦可將實施形態2與5加以組合。***Description of composition***
Fig. 14 is a configuration diagram of a screen printing apparatus 100 according to the sixth embodiment. The screen printing apparatus 100 of the sixth embodiment applies the belt moving mechanism 40 and the driving part 170 of the driving mechanism 70 of the second embodiment to the screen printing apparatus 100 of the fifth embodiment. In this way, Embodiments 2 and 5 can also be combined.
實施形態7.
於實施形態7中，對與實施形態5之不同點進行說明。Implementation mode 7.
In the seventh embodiment, the differences from the fifth embodiment will be described.
***構成之說明***
圖15、圖16係實施形態7之基座50與移動平台150之前視構成圖與AA線剖面圖。實施形態7之移動平台150係使實施形態1之移動平台150之構成簡化，而將固定板99直接固定於平台軸156者。根據實施形態7，移動平台150之構成變簡單。***Description of composition***
15 and 16 are a front view of the structure of the base 50 and the mobile platform 150 and the cross-sectional view along the line AA of the seventh embodiment. The mobile platform 150 of the seventh embodiment simplifies the structure of the mobile platform 150 of the first embodiment, and the fixed plate 99 is directly fixed to the platform shaft 156. According to the seventh embodiment, the structure of the mobile platform 150 is simplified.
實施形態8.
於實施形態8中，對與上述實施形態之不同點進行說明。Embodiment 8.
In the eighth embodiment, the difference from the above-mentioned embodiment will be described.
***構成之說明***
圖17係實施形態7之網版印刷方法之流程圖。實施形態8之圖17與實施形態1之圖6之不同點在於以下兩點。***Description of composition***
Fig. 17 is a flowchart of the screen printing method of the seventh embodiment. The difference between FIG. 17 of Embodiment 8 and FIG. 6 of Embodiment 1 is the following two points.
不同點1
本實施形態之控制部110於印刷部60對工件69的印刷時，僅執行印刷部60對工件69的印刷。於圖17中，於印刷步驟S13a與印刷步驟S13b之執行時，停止其他動作。亦即，皮帶循環開始步驟15b會在印刷步驟S13a結束之後開始。又，皮帶循環開始步驟15a會在印刷步驟S13b結束之後開始。由於在印刷步驟S13a與印刷步驟S13b之執行時不執行其他動作，因此於印刷時不會產生因其他動作所產生之振動。因此，可進行準確之印刷。Difference 1
The control unit 110 of this embodiment only executes the printing of the work 69 by the printing unit 60 when the work 69 is printed by the printing unit 60. In FIG. 17, when the printing step S13a and the printing step S13b are executed, other actions are stopped. That is, the belt loop start step 15b will start after the printing step S13a ends. In addition, the belt loop start step 15a starts after the printing step S13b ends. Since no other actions are performed during the execution of the printing step S13a and the printing step S13b, vibrations caused by other actions will not be generated during printing. Therefore, accurate printing can be performed.
不同點2
本實施形態之控制部110於工件搭載部30之工件69的設置時，僅執行工件搭載部30之工件69的設置。於圖17中，於工件設置、抽氣開始步驟S11a與工件設置、抽氣開始步驟S11b之執行時，停止其他動作。亦即，印刷刮漿板之移動會在工件設置、抽氣開始步驟S11b結束之後開始。又，印刷刮漿板之移動會在工件設置、抽氣開始步驟S11a結束之後開始。由於在工件設置、抽氣開始步驟S11a與工件設置、抽氣開始步驟S11b之執行時不執行其他動作，因此於工件之定位時不會產生因其他動作所產生之振動。因此，可進行準確之定位。Difference 2
When setting the workpiece 69 of the workpiece loading unit 30, the control unit 110 of the present embodiment only executes the setting of the workpiece 69 of the workpiece loading unit 30. In FIG. 17, other actions are stopped when the workpiece setting, the pumping start step S11a and the workpiece setting, the pumping start step S11b are executed. That is, the movement of the printing squeegee will start after the workpiece setting and the air extraction start step S11b ends. In addition, the movement of the printing squeegee will start after the completion of the work setting and the exhaust start step S11a. Since no other actions are performed during the execution of the workpiece setting, the pumping start step S11a and the workpiece setting, and the pumping start step S11b, there will be no vibration caused by other actions during the positioning of the workpiece. Therefore, accurate positioning can be performed.
亦可僅執行不同點1與不同點2之任一者。It is also possible to execute only one of difference point 1 and difference point 2.
***實施形態之補充***
於實施形態中，雖已對網版印刷裝置100之情形進行說明，但皮帶驅動裝置200並不限定於使用於網版印刷裝置100，而可使用於其他裝置。例如，皮帶驅動裝置200可藉由取代印刷部60而使用塗裝部、表面加工部等來使用於塗裝裝置、表面加工裝置等。***Supplement to the implementation form***
In the embodiment, although the screen printing device 100 has been described, the belt drive device 200 is not limited to being used in the screen printing device 100 and can be used in other devices. For example, the belt drive device 200 can be used in a coating device, a surface processing device, etc., by using a coating portion, a surface processing portion, etc., instead of the printing portion 60.
控制部110之功能亦可由軟體與硬體之組合來實現。亦即，亦可由軟體來實現控制部110之一部分，並由硬體來實現控制部110之其餘部分。The function of the control unit 110 can also be realized by a combination of software and hardware. That is, a part of the control unit 110 can also be realized by software, and the rest of the control unit 110 can be realized by hardware.
實施形態係較佳之形態的例示，並非意圖限制本發明之技術範圍者。實施形態既可局部地加以實施，亦可與其他形態組合而實施。又，亦可將上述實施形態加以組合。使用流程圖等所說明之順序係本發明之方法或程式之順序之一例。The embodiment is an illustration of a preferable form, and is not intended to limit the technical scope of the present invention. The embodiment can be implemented partially or in combination with other forms. In addition, the above-mentioned embodiments may be combined. The sequence described using the flowchart and the like is an example of the sequence of the method or program of the present invention.
