Description

P4161NL01 1 A Method of Transporting a Media Web The invention relates to a method of transporting a media web through a printing system, the printing system comprising: - a first bearing support arranged for rotatably supporting a first media roll of a first media web, - a second bearing support arranged for rotatably supporting a second media roll of a second media web, - a print transport path, - a first supply path extending from the first bearing support to the print transport path, and - a second supply path extending from the second bearing support to the print transport path, the method comprising a step of attaching a length of the first media web as a leader section to a leading edge of the second media web. In a printing system arranged for printing on an endless media web that is withdrawn from a roll, a web transport system comprises several pairs of pinch rollers and guide plates that define a transport path for the web. When the web is pinched in the nip between a pair of pinch rollers, it can be advanced in transport direction, and the leading edge of the web is pushed through the path that is defined between the guide plates. However, if the web is limp or sticky, there is a risk that the leading edge gets caught and the web jams in the transport path.
In order to solve this problem, EP 3 214 027 B1 describes a method and a printing system of the type indicated above, wherein, when a limp media web has to be fed into the print transport path, a leader section that consists of a stiffer web material is attached to the leading edge of the limp web. The leader section is cut from the second media roll of the second media web that is made of the stiffer material. In the known method, the operations of cutting the leader section from the second media web and attaching it to the first web are performed in a storage compartment of the printer which accommodates the bearing supports and the media rolls. Then, due to the stiffness of the leader section that forms the leading edge of the web, the first media
P4161NL01 2 web can be safely fed into the print transport path, and the limper main part of the web will be drawn through the transport path by the leader section. It is an object of the invention to provide a method in which the operation of attaching the leader section to the web can be performed more easily. In order to achieve this object, the method according to the invention is characterized by the steps of: (a) supplying the first media web into the print transport path, (bp) cutting the first media web, thereby to separate the leader section from a remainder of the first media web, (©) withdrawing the remainder of the first media web into the first supply path, (d) supplying the second media web into the print transport path, (e) attaching a trailing end of the leader section to the leading edge of the second media web in the print transport path, and (f) transporting the leader section and second media web through the print transport path. This method has the advantage that the operations of cutting the leader section of the first web and attaching it to the second web, which operations typically involve manual work, do not have to be performed in the storage compartment of the printer, where access to the media rolls is restricted, but in the print transport path which is more readily accessible for the user. Moreover, the same transport mechanisms that are normally used for supplying the first or the second media web to the print transport path can also be used for bringing the webs into a suitable position for the operations of cutting and attaching. When these operations are completed, the leader section is already in the print transport path, so that the printing process can start more quickly. No spooling of the webs from one roll to the other nor a flip of the orientation of any of the rolls in the bearing support is required.
More specific optional features of the invention are indicated in the dependent claims. The invention also relates to a printing system configured for carrying out the method described above.
P4161NL01 3 An embodiment example will now be described in conjunction with the drawings, wherein: Fig. 1 is a schematic view of essential parts of a roll-to-roll-printer according to the invention; and Figs. 2t06 are views analogous to Fig. 1 and show successive steps of the method according to the invention.
As is shown in Fig. 1, a roll-to-roll-printer has a storage compartment 10 accommodating a first media roll 12 of a media web 14 rotatably supported on a first bearing support 16, and a second media roll 18 of a second media web 20 rotatably supported on a second bearing support 22. The storage compartment 10 may be configured as a drawer that can be drawn out of a body of the printer for loading new media rolls. The printer further comprises a print transport path 24 comprising guide plates 28 that define a passage along which the first media web 14 or the second media web 20 can be guided onto a platen 28 that constitutes a downstream part of the print transport path
24. The transport path 24 comprises a tiltable curved medium support surface 25, as known from EP 3248921 (B1), which is herein incorporated by reference. The first media web 14 bends along the curved medium support surface 25 towards the platen 28, thereby exerting a force on the curved medium support surface. In response to said force the curved medium support surface 25 may tilt. Displacement or tilt sensors 25° are provided to measure the displacement of the curved medium support surface 25. Said measured displacement may be used to determine a displacement of the first media web 14 on the platen 28 with respect to the intended path of the print station. Although not shown in the drawings, a print engine, e.g. an ink jet print head assembly, is disposed above the platen 28 and configured for printing an image onto the media web that is passed over the platen.
P4161NL01 4 A pair of pinch rollers 30 is arranged at an entry side of the platen 28 for drawing the web through an upstream part of the print transport path 24 and pushing it onto the platen 28.
The printer further comprises a first supply path 32 extending from the first bearing support 16 to the print transport path 24, and a second supply path 34 extending from the second bearing support 22 to the print transport path 24. The first and second supply paths 32, 34 merge into a vertically oriented upstream part of the print transport path 24, this part being configured as a cut-and-join station 36. Each of the first and second supply paths 32, 34 includes a pair of pinch rollers 38, 40 for drawing off the respective web from the media roll 12, 18 and pushing it into the print transport path 24. An electronic controller 42, which has only been shown symbolically in Fig. 1, is arranged for controlling the functional components of the printer, including drive motors for the bearing supports 16, 22 and the pairs of pinch rollers 30, 38, 40. A vertical branch of the print transport path 24 that includes the cut-and-join station 36 is covered by a removable cover 44. The cover 44 is preferably mounted on a hinge, such that pivoting the cover 44 removes the cover 44 from an access opening through which the cut-and-join station 36 is accessible to an operator. A sensor unit 46 is disposed at the vertical branch of the print transport path 24 in a position opposite to the cover 44 and is connected to the controller 42. When a print job requires that an image is to be printed, for example onto the first media web 14, the controller 42 activates the first bearing support 16 and the pair of pinch rollers 38, so that the web 14 is unwound from the first media roll 12 and is advanced through the supply path 32 into the print transport path 24. When the leading edge of the web has entered into the vertical branch of the print transport path 24, the leading part of the web is pushed upwards by the drive force that is exerted by the pair of print rollers 38, so that the leading edge will eventually reach the nip between the pair of pinch rollers 30 at the entry of the platen 28. Then, the web will be seized by the pair of pinch rollers 30 and will be drawn through the vertical branch of the print transport path 24 and pushed onto the platen 28. In the example shown, it is assumed that the first media web 14 is made of a relatively stiff material, whereas the second media web 20 is made of a relatively limp or weak
P4161NL01 material or a sticky material.
Due to the weakness of the second media web 20, there is a risk that the leading edge of the web cannot be pushed forward up to the pair of pinch rollers 30, because the frictional resistance in the print transport path 24 is so large that the web tends to buckle and to get jammed between the guide plates 26. For this 5 reason, if the second media web 20 is to be used for printing, a certain length of the first media web 14 is withdrawn and cut from the first media roll 12 so as to form a leader section that is then joined to the leading end of the weaker second media web 20. Consequently, a leading part of the second media web 20 will be formed by the stiffer leader section that can smoothly be pushed through the print transport path 24 until it is caught by the pair of pinch rollers 30. Then, the leader section and, thereafter, the part of the weaker web 20 that is pinched between the pair of pinch rollers 30 can safely draw the trailing part of the web through the print transport path.
The procedure that is applied when the printer is in the condition shown in Fig. 1 and a print job requires that an image is to be printed onto the weaker second media web 20 will now be described by reference to Figs. 2 to 6. It should be observed that the positions of the first and second media rolls 12 and 18 on the first and second media supports 16 and 22 might also be reversed, so that the weaker web would be withdrawn from the first bearing support 16. In any case, information on which type of media web is mounted on which bearing support is stored in the controller 42, so that the leader section will in any case be withdrawn from the media roll that contains the stiffer material, i.e. from the media roll 12 in this example.
The reversal may further be combined with printing on the inward facing side of a media roll, as known from EP3280367 (B1), which is incorporated herein by reference.
The media roll with the stiffer material is positioned on the second bearing support 22, from which a leader section is fed via pinch rollers 40. The media roll on the second bearing support 22 is then replaced by a guide element, for example an empty roll core of a media roll.
Preferably, the leader section is cut before replacing the media roll to allow the tray to be opened.
The weaker media is positioned on the first bearing support 16, however with the media roll in a winding direction reversed as compared to Figs. 1-6. The weaker media is unwound in a reversed direction as compared to Figs. 1-6 and guided via the guide element through pinch roller 40 for attachment to the leader section.
P4161NLO1 6 Thus, although the print job requires the second media web 20 to be the print medium, the controller will at first activate the first bearing support 16 and the pair of pinch rollers 38 for advancing the first media web 14 onto the platen 28, as has been shown in Fig. 2. When the condition shown in Fig. 2 has been reached, a user interface (not shown) of the printer will prompt the user or operator to open or remove the cover 44 so as to expose the portion of the web 14 that is located in the cut-and-join station 36.
In the condition shown in Fig. 3, the cover 44 has been removed or pivoted to its open position, so that the web 14 is accessible in the cut-and-join station 36. The user may now use a knife 48 for manually cutting the web 14 along a cut line that extends transverse to the longitudinal direction of the web. The knife 48 may be guided in a slit that is formed between two of the guide plates 26, so that a smooth cut is obtained.
When the cut has been performed, the user may notify this to the controller by tapping onto the sensor unit 46 or the curved medium support surface 25 connected to sensor unit 25’. The sensor units 25’, 46 may include a displacement sensor, a touch switch, a vibration sensor, or a proximity sensor for that purpose.
In Fig. 4, the cut has been performed, and the part of the web 14 that use to be leading part of the web and that is accommodated in the print transport path 24 and is held in the nip between the pair of pinch rollers 30 is separated from the remainder of the web and now constitutes a leader section 50 that is to be joined to the second web 20.
As soon as it has been confirmed that the cut has been made, the first bearing support 16 and the pair of pinch rollers 38 are driven in the opposite direction so as to withdraw the remainder of the web 14 into the position that has been shown in Fig. 4. Then, the second bearing support 22 and the pair of pinch rollers 40 are activated so as to advance the second media web 20 into the position shown in Fig. 4. In this position, the leading end of the web 20 has a slight overlap with the trailing end of the leader section
50.
Then, as has been shown in Fig. 5, the leading end of the weaker web 20 and the trailing end of the leader section 50 are manually joined together by means of an
P4161NL01 7 adhesive tape 52. In that process, the webs may be supported by a vertical wall of one of the guide plates 26 that delimits the transport path on the side of the sensor unit 48. Then, as is shown in Fig. 8, the user places the cover 44 back in its closed position, and the sensor unit 46 detects, e.g. by means of a magnetic switch, that the cover is in place again. This event triggers a command of the controller 42 to drive the second bearing support 22, the pair of pinch rollers 40 and also the pair of pinch rollers 30 for advancing the weaker second media web 20 with the leader section 50 attached thereto further towards the platen 28. In the situation shown in Fig. 6, the joint between the leader section 50 and the web 20, constituted by the adhesive tape 52, has reached a position on the platen 28. Now, optionally, the leader section 50 and the adhesive tape 52 may be removed. In any case, the weaker web 20 may be advanced further over the platen by means of the pair of pinch rollers 30, so that an image can be printed onto the web
20.
