Description
本發明係關於一種薄片進料搬送裝置及利用薄片進料搬送裝置之印刷機。 The present invention relates to a sheet feeding conveying apparatus and a printing machine using the sheet feeding conveying apparatus.
例如特開2012-25094號公報揭示了一種滾筒型網版印刷機。在揭示於此文獻上的印刷機方面，首先，利用薄片進料搬送裝置將單張薄片往可旋轉的印刷滾筒搬送。接著，在印刷滾筒上定好單張薄片的位置後，利用橡皮輥加壓網框之網版，印刷印刷滾筒上的單張薄片。薄片進料搬送裝置係將單張薄片載置於搬送帶上搬送。此時，為了提高搬送帶的單張薄片之搬送力，在搬送帶上將單張薄片利用輥等的推壓構件壓住、或者通過設置於搬送帶上的吸引孔吸附。 For example, Japanese Laid-Open Patent Publication No. 2012-25094 discloses a drum type screen printing machine. In the printing machine disclosed in this document, first, a single sheet is conveyed to a rotatable printing cylinder by a sheet feeding conveyance device. Next, after the position of the individual sheets is set on the printing cylinder, the screen of the frame is pressed by the squeegee to print a single sheet on the printing cylinder. In the sheet feeding conveyance device, a single sheet is placed on a conveyance belt and conveyed. At this time, in order to increase the conveyance force of the single sheet of the conveyance belt, a single sheet is pressed by a pressing member such as a roller on the conveyance belt, or is suctioned by a suction hole provided in the conveyance belt.
然而，利用輥等的推壓構件將單張薄片壓在搬送帶上的情況，推壓構件直接接觸於單張薄片。因此，單張薄片的印刷面上會受傷、或者污垢會附著。此外，在搬送帶上吸附單張薄片的情況，吸引力的調整困難。即，吸引力不適當時，無法良好地搬送單張薄片。此外，也無法良好地進行印刷前所實行的單張薄片的對準動作。 However, when a single sheet is pressed against the conveyor belt by a pressing member such as a roller, the pressing member directly contacts the single sheet. Therefore, the printed surface of the single sheet may be damaged or dirt may adhere. Further, in the case where a single sheet is adsorbed on the conveyor belt, it is difficult to adjust the attraction force. That is, when the attraction is not appropriate, the single sheet cannot be conveyed satisfactorily. Further, the alignment operation of the individual sheets which are performed before printing cannot be performed satisfactorily.
本發明之目的在於在各種用途的薄片進料搬送裝置，例如滾筒型網版印刷機所採用的薄片進料搬送裝置方面，解決上述問題。此外，本發明之目的在於提供一種利用薄片進料搬送裝 置之印刷機。 An object of the present invention is to solve the above problems in a sheet feeding conveyance device for various uses, for example, a sheet feeding conveyance device used in a drum type screen printing machine. Further, it is an object of the present invention to provide a sheet feeding and conveying device Set the press.
為了達成上述目的，在本發明之一態樣方面，提供一種利用搬送體搬送單張薄片之薄片進料搬送裝置。薄片進料搬送裝置具備朝向載置於搬送體上的單張薄片噴出氣體的吸引筒。薄片進料搬送裝置在吸引筒端部與單張薄片之間形成用以使氣體流出的間隔。此外，薄片進料搬送裝置利用流經間隔的氣體之吸引作用，將單張薄片保持於前述搬送體上而搬送。 In order to achieve the above object, in one aspect of the invention, a sheet feeding conveyance device that conveys a single sheet by a conveyance body is provided. The sheet feeding conveyance device includes a suction cylinder that ejects gas toward a single sheet placed on the conveying body. The sheet feeding conveyance device forms a space for the gas to flow out between the end portion of the suction cylinder and the single sheet. Further, the sheet feeding conveyance device transports a single sheet on the conveyance body by the suction action of the gas flowing through the space.
以下，就關於本發明第1實施形態之滾筒型網版印刷機及薄片進料搬送裝置，參照圖1A~圖2進行說明。 Hereinafter, the drum type screen printing machine and the sheet feeding conveyance apparatus according to the first embodiment of the present invention will be described with reference to Figs. 1A to 2 .

The sheet feeding conveyance device 2 is disposed on the upstream side of the printing drum 1 in the conveyance direction X of the sheet 7 . The single sheet take-out device 3 is disposed on the downstream side of the printing cylinder 1. The printing device 4 is disposed above the printing cylinder 1.
薄片進料搬送裝置2具備搬送輸送帶5。從送料器6一片一片地送出單張薄片7到搬送輸送帶5的搬入側端部。然後，單張薄片7被搬送到搬送輸送帶5的搬出側端部。在印刷前，進行單張薄片7的對準調整。因此，在單張薄片7的搬送方向X的下游端設有前套準板(未圖示)。前套準板鄰接於印刷滾筒1配置。此外，橫套準板(未圖示)設於搬送輸送帶5的兩側部。單張薄片7從搬送輸送帶5的搬入側端部被搬送到搬出側端部後，抵接於前套準板，並被橫套準板夾持。如此定好單張薄片7的 位置後，為設置於印刷滾筒1上的夾持器8所把持。 The sheet feeding conveyance device 2 includes a conveyance belt 5 . The single sheet 7 is fed one by one from the feeder 6 to the loading side end of the conveying conveyor 5. Then, the single sheet 7 is conveyed to the carry-out end portion of the conveyance conveyor belt 5. The alignment adjustment of the individual sheets 7 is performed before printing. Therefore, a front registration plate (not shown) is provided at the downstream end of the conveyance direction X of the single sheet 7. The front registration plate is disposed adjacent to the printing cylinder 1. Further, horizontal registration plates (not shown) are provided on both sides of the conveyance conveyor 5. The sheet sheet 7 is conveyed to the carry-out side end portion from the loading side end portion of the conveyance belt 5, and then abuts against the front registration plate and is sandwiched by the horizontal registration plate. So that the sheet leaf 7 is fixed After the position, it is held by the holder 8 provided on the printing cylinder 1.
在印刷滾筒1的上方支持著印刷網框9。印刷網框9在印刷滾筒1的搬入側端部與搬出側端部之間往復移動。即，印刷網框9沿著單張薄片7的搬送方向X而水平地往復移動。在印刷網框9的內側張設有網版9a。在網版9a的上方，可於上下方向上移動地支持著刮刀10及橡皮輥11。 A printing frame 9 is supported above the printing cylinder 1.

That is, the printing frame 9 is horizontally reciprocated along the conveying direction X of the single sheet 7. A screen 9a is stretched inside the printing frame 9. Above the screen 9a, the blade 10 and the rubber roller 11 are supported movably in the up and down direction.
印刷結束後，使印刷網框9從印刷結束位置回到印刷開始位置之際，刮刀10向下方移動。然後，刮刀10在網版9a上塗布油墨。單張薄片7為夾持器8所把持，決定單張薄片7對於印刷滾筒1的位置。其後，單張薄片7和印刷滾筒1共同旋轉。於是，印刷網框9與印刷滾筒1的旋轉同步從印刷開始位置移動到印刷結束位置。當時，橡皮輥11向下方移動，利用橡皮輥11將網版9a推壓於印刷滾筒1上。如此對於印刷滾筒1上的單張薄片7進行印刷。此時，印刷係從單張薄片7的搬入側端部依次進行。 After the printing is completed, when the printing frame 9 is returned from the printing end position to the printing start position, the blade 10 is moved downward. Then, the doctor blade 10 coats the ink on the screen 9a. The single sheet 7 is held by the holder 8 and determines the position of the sheet 7 against the printing cylinder 1. Thereafter, the single sheet 7 and the printing cylinder 1 rotate together. Then, the printing frame 9 is moved from the printing start position to the printing end position in synchronization with the rotation of the printing cylinder 1. At that time, the rubber roller 11 is moved downward, and the screen 9a is pressed against the printing cylinder 1 by the rubber roller 11. Thus, a single sheet 7 on the printing cylinder 1 is printed. At this time, the printing system is sequentially performed from the loading side end portion of the single sheet 7.
其次，就設置於搬送輸送帶5上的非接觸式搬送裝置12，參照圖1A及圖1B進行說明。 Next, the non-contact conveying apparatus 12 provided on the conveying conveyor 5 will be described with reference to FIGS. 1A and 1B.

The pressure control valve 24 or the flow rate control valve 24 is disposed between the supply of the gas to the gas supply pump 23 in each of the suction cylinders 15 and the suction cylinders 15 of each group. The gas suction pump 25 is connected to the suction plate 16. The gas suction pump 25 imparts attraction to a plurality of suction holes (not shown) provided on the suction plate 16.
如圖1B所示，搬送輸送帶5除了非接觸式搬送裝置12之外，還具備作為氣體回收機構的氣體回收裝置26。氣體回收裝置26回收從吸引筒15流出的氣體。氣體回收裝置26於搬送台 13的兩側部具備管道28。利用氣體吸引泵浦27，通過管道28吸引從吸引筒15流出的氣體。 As shown in FIG. 1B, the conveyance conveyor 5 includes a gas recovery device 26 as a gas recovery mechanism in addition to the non-contact conveyance device 12. The gas recovery device 26 recovers the gas flowing out of the suction cylinder 15. Gas recovery device 26 on the transfer table A pipe 28 is provided at both sides of the 13 . The gas is sucked by the suction pump 27, and the gas flowing out of the suction cylinder 15 is sucked through the duct 28.
其次，參照圖1A~圖2說明非接觸式搬送裝置12所進行的單張薄片7之搬送作用。 Next, the transfer operation of the individual sheets 7 by the non-contact conveying apparatus 12 will be described with reference to Figs. 1A to 2 .
如圖1A所示，首先，從送料器6一片一片地送出單張薄片7到搬送輸送帶5的搬入側端部。於是，單張薄片7被配置於吸引筒15的上方，並且被載置於搬送帶14上的搬送面14a上。 As shown in FIG. 1A, first, a single sheet 7 is fed one by one from the feeder 6 to the loading side end portion of the conveying conveyor 5. Then, the single sheet 7 is placed above the suction cylinder 15 and placed on the conveying surface 14a of the conveyor belt 14.
如圖2所示，來自氣體供應泵浦23的氣體(空氣)通過壓力控制閥24或流量控制閥24供應給吸引筒15之流入口19。然後，來自氣體供應泵浦23的氣體從吸引筒15之壓力室20通過流出口21，朝向載置於搬送帶14上的單張薄片7噴出。同時，來自氣體供應泵浦23的氣體通過上端凸緣部17a與單張薄片7之間的微小間隔G(例如約0.1mm)流出。 As shown in FIG. 2, the gas (air) from the gas supply pump 23 is supplied to the inflow port 19 of the suction cylinder 15 through the pressure control valve 24 or the flow control valve 24. Then, the gas from the gas supply pump 23 is discharged from the pressure chamber 20 of the suction cylinder 15 through the outflow port 21 toward the single sheet 7 placed on the conveyor belt 14. At the same time, the gas from the gas supply pump 23 flows out through a minute gap G (for example, about 0.1 mm) between the upper end flange portion 17a and the single sheet 7.
於開始印刷前，壓力室20內的氣體之壓力為壓力控制閥24或流量控制閥24所調節。利用在壓力室20增減的氣體之壓力，在單張薄片7與上端凸緣部17a之間產生微小的間隔G。因此，單張薄片7和吸引筒15被維持在非接觸狀態。此外，單張薄片7為氣體流經間隔G而產生的負壓所吸引。藉此，單張薄片7接觸於搬送帶14之搬送面14a而被保持。 The pressure of the gas in the pressure chamber 20 is regulated by the pressure control valve 24 or the flow control valve 24 before the start of printing. A slight gap G is generated between the single sheet 7 and the upper end flange portion 17a by the pressure of the gas which is increased or decreased in the pressure chamber 20. Therefore, the single sheet 7 and the suction cylinder 15 are maintained in a non-contact state. Further, the individual sheets 7 are attracted by a negative pressure generated by the gas flowing through the gap G. Thereby, the single sheet 7 is held in contact with the conveying surface 14a of the conveying belt 14.
即，氣體以高速通過上端凸緣部17a與單張薄片7的間隔G。因此，在間隔G的壓力降低時，吸引單張薄片7之類的向下之力開始起作用。此外，通過間隔G的氣體也起作用作為緩衝物，對於單張薄片7賦予向上之力。按照如上述的向下之力與向上之力的平衡設定間隔G，以保持單張薄片7。 That is, the gas passes through the gap G between the upper end flange portion 17a and the single sheet 7 at a high speed. Therefore, when the pressure of the gap G is lowered, the downward force attracting the single sheet 7 starts to function. Further, the gas passing through the gap G also functions as a buffer, and an upward force is applied to the single sheet 7. The interval G is set in accordance with the balance of the downward force and the upward force as described above to hold the single sheet 7.
如圖1所示，被吸引於搬送帶14之搬送面14a上的單張薄 片7利用搬送帶14被往印刷滾筒1搬送。然後，吸引板16吸引單張薄片7，並在該狀態下調整單張薄片7的方向。其後，搬送帶14停止，利用夾持器8把持單張薄片7。然後，決定單張薄片7對於印刷滾筒1的位置。當時，印刷滾筒1旋轉到開始印刷之間，吸引板16利用自己的吸引力繼續保持單張薄片7。再者，從吸引筒15流出的氣體被氣體吸引泵浦27吸引到管道28而被回收。 As shown in FIG. 1, the sheet is attracted to the conveying surface 14a of the conveying belt 14 The sheet 7 is conveyed to the printing cylinder 1 by the conveyance belt 14. Then, the attraction plate 16 attracts the single sheet 7, and adjusts the direction of the individual sheets 7 in this state. Thereafter, the conveyor belt 14 is stopped, and the single sheet 7 is held by the gripper 8. Then, the position of the sheet 7 to the printing cylinder 1 is determined. At that time, the printing cylinder 1 was rotated until the start of printing, and the attraction plate 16 continued to hold the single sheet 7 with its own attractive force. Further, the gas flowing out of the suction cylinder 15 is sucked into the duct 28 by the gas suction pump 27 to be recovered.
以下，就關於本發明第2實施形態之滾筒型網版印刷機及薄片進料搬送裝置，參照圖3A及圖3B進行說明。再者，關於第2實施形態之和第1實施形態同樣的部分，省略其詳細的說明。 Hereinafter, the drum type screen printing machine and the sheet feeding conveyance apparatus according to the second embodiment of the present invention will be described with reference to Figs. 3A and 3B. In the second embodiment, the same portions as those in the first embodiment are not described in detail.
如圖3B所示，在搬送台13上，於搬送中心12a的兩側分別設置各2條搬送帶14。各搬送帶14排列於搬送台13的寬度方向Y上。在搬送台13的搬送中心12a附近，全部配置有6組各2個排列於寬度方向Y上的吸引筒15之組。此等吸引筒15配置於隔著搬送中心12a的一對搬送帶14間。此外，在隔著搬送中心12a的一對搬送帶14的各搬送帶與鄰接於外側的搬送帶14之間分別配置有5個吸引筒15。吸引筒15從搬送輸送帶5的搬入側端部到搬出側端部配置成四排。 As shown in FIG. 3B, on the transfer table 13, two transfer belts 14 are provided on both sides of the transfer center 12a. Each of the conveyor belts 14 is arranged in the width direction Y of the conveyance table 13. In the vicinity of the transport center 12a of the transport table 13, all of the six sets of the suction cylinders 15 arranged in the width direction Y are disposed. These suction cylinders 15 are disposed between the pair of conveyor belts 14 that are separated from the conveyance center 12a. Further, five suction cylinders 15 are disposed between the respective conveyor belts of the pair of conveyor belts 14 that are separated from the conveyor center 12a and the conveyor belts 14 that are adjacent to the outside. The suction cylinders 15 are arranged in four rows from the loading side end portion of the conveying conveyor belt 5 to the carrying-out side end portion.
如圖3A所示，壓力調節裝置22在排列於寬度方向Y上的4個1組的吸引筒15及2個1組的吸引筒15的各吸引筒上具有各1個壓力控制閥24或流量控制閥24。再者，也可以省略4個1組的吸引筒15之中，位於搬送中心12a兩側的兩搬送帶14 間的吸引筒15。 As shown in FIG. 3A, the pressure adjusting device 22 has one pressure control valve 24 or a flow rate in each of the four suction cylinders 15 and the two suction cylinders 15 arranged in the width direction Y. Control valve 24. Further, among the four suction cylinders 15 of one set, the two conveyor belts 14 located on both sides of the transport center 12a may be omitted. The suction cylinder 15 between.
因此，上述各實施形態可取得如下的效果： Therefore, the above embodiments can achieve the following effects:
(1)單張薄片7在被吸引而接觸於搬送帶14的狀態下被搬送到印刷滾筒1。因此，不需要將單張薄片7壓在搬送帶14上的輥等的推壓構件。因而，在單張薄片7的印刷面上不會因推壓構件而受傷、或者污垢附著。 (1) The sheet sheet 7 is conveyed to the printing cylinder 1 while being sucked and brought into contact with the conveyance belt 14. Therefore, it is not necessary to press a single sheet 7 against a pressing member such as a roller on the conveying belt 14. Therefore, the printed surface of the single sheet 7 is not injured by the pressing member or the dirt adheres.
(2)吸引筒15朝向載置於搬送帶14上的單張薄片7噴出氣體。來自吸引筒15的氣體在上端凸緣部17a與單張薄片7之間形成間隔G。利用流經間隔G的氣體，吸引作用及緩衝作用的兩方作用於單張薄片7。藉此，可使單張薄片7不接觸於吸引筒15之上端凸緣部17a而進行保持。在此狀態下，單張薄片7被往印刷滾筒1搬送。因此，使單張薄片7的搬送狀態成為適當的狀態，可防止單張薄片7的搬送不良。此外，利用前套準板或橫套準板進行單張薄片7的對準調整之情況，調節在吸引筒15內增減的氣體之壓力。藉此，將單張薄片7的搬送狀態設定為適當的狀態，可相對於搬送帶14容易使單張薄片7移動。因此，也可以防止單張薄片7的印刷前對準動作不良。 (2) The suction cylinder 15 ejects gas toward the single sheet 7 placed on the conveyor belt 14. The gas from the suction cylinder 15 forms a space G between the upper end flange portion 17a and the single sheet 7. Both the suction action and the buffering action act on the individual sheets 7 by the gas flowing through the gap G. Thereby, the single sheet 7 can be held without being in contact with the upper end flange portion 17a of the suction cylinder 15. In this state, the single sheet 7 is conveyed to the printing cylinder 1. Therefore, the conveyance state of the single sheet 7 is made into an appropriate state, and the conveyance failure of the single sheet 7 can be prevented. Further, the pressure of the gas which is increased or decreased in the suction cylinder 15 is adjusted by the alignment adjustment of the single sheet 7 by the front registration plate or the horizontal registration plate. Thereby, the conveyance state of the single sheet 7 is set to an appropriate state, and it is easy to move a single sheet 7 with respect to the conveyance belt 14. Therefore, it is also possible to prevent the pre-printing alignment operation of the individual sheets 7 from being defective.
(3)吸引筒15配置於隔著搬送中心12a的兩側的搬送帶14間。此外，吸引筒15排列於單張薄片7的搬送方向X上。並且，吸引筒15也排列於搬送台13的寬度方向Y上。藉由此等排列，可賦予單張薄片7均等的搬送力，藉此，可順利地搬送單張薄片7。 (3) The suction cylinder 15 is disposed between the conveyor belts 14 on both sides of the conveyance center 12a. Further, the suction cylinders 15 are arranged in the conveying direction X of the single sheet 7. Further, the suction cylinders 15 are also arranged in the width direction Y of the conveyance table 13. By this arrangement, it is possible to impart a uniform conveying force to the single sheet 7, whereby the single sheet 7 can be smoothly conveyed.
(4)壓力調節裝置22在複數組的吸引筒15的各吸引筒上具有各1個壓力控制閥24或流量控制閥24。壓力控制閥24或流量控制閥24可變更各組的吸引筒15內的氣體之壓力或流量。 例如，若將吸引筒15內的壓力在搬送輸送帶5的搬入側端部設定得高於搬出側端部，則可增大作用於單張薄片7的向下之力，所以可順利地搬送單張薄片7。此外，若將吸引筒15內的壓力在搬送輸送帶5的搬出側端部設定得低於搬入側端部，則作用於單張薄片7的向上之力變大，所以可容易進行單張薄片7的印刷前對準動作。 (4) The pressure adjusting device 22 has one pressure control valve 24 or a flow rate control valve 24 in each of the suction cylinders of the plurality of suction cylinders 15 . The pressure control valve 24 or the flow control valve 24 can change the pressure or flow rate of the gas in the suction cylinders 15 of each group. For example, when the pressure in the suction cylinder 15 is set higher than the carry-out end portion of the transport conveyor 5, the downward force acting on the single sheet 7 can be increased, so that the pressure can be smoothly transported. Single sheet 7. In addition, when the pressure in the suction cylinder 15 is set lower than the loading-side end portion of the conveyance belt 5, the upward force acting on the sheet 7 is increased, so that the sheet can be easily formed. 7 pre-printing alignment action.
(5)利用氣體吸引泵浦27，通過管道28吸引從吸引筒15流出的氣體。因此，可防止粉塵或塵埃等滯留於薄片進料搬送裝置2上。此外，也可以使從吸引筒15噴出的氣體不流到印刷網框9。因此，可抑制塗布於印刷網框9之網版9a上的油墨之乾燥。 (5) The pump 27 is sucked by the gas, and the gas flowing out of the suction cylinder 15 is sucked through the duct 28. Therefore, it is possible to prevent dust, dust, and the like from remaining on the sheet feeding conveyance device 2. Further, the gas ejected from the suction cylinder 15 may not flow to the printing frame 9. Therefore, drying of the ink applied to the screen 9a of the printing frame 9 can be suppressed.
