Inkjet printing system with a transportation and storage container for web material for forming an air permeable, endless transport belt

BACKGROUND OF THE INVENTION

1. Field of the invention

The invention relates to a transportation and storage container for web material for forming an air permeable, endless transport belt and a method for forming such a transport belt. 2. Description of Background Art

Endless transport belts are applied in inkjet printers to transport a print medium along an inkjet printhead assembly. The belts are air permeable and positioned over a suction chamber, which applies an underpressure to the print medium through the belt. The belts are generally formed from a web material, such as film. The web material is processed into such an endless belt in several steps. The processing steps include cutting the web material to a predetermined length, perforating the web material to form a plurality of through-holes therein, and/or fixing the ends of the cut material together to form an endless belt. Transportation and/or storage containers for transporting such web materials between the different processing steps and their installation in a printer are known. Such containers are generally boxes comprising one or more rollers inside them, wherein the web material can be pulled out of the box via an opening. It was however found that using such boxes resulting a loss of web material due to relatively long exposure of the web material to ambient conditions between processing and storage steps.

SUMMARY OF THE INVENTION

It is an object of the invention to provide transportation and storage container for web material which helps improve the efficiency of web material use.

In accordance with the present invention, a container according to claim 1 and a method according to claim 9 are provided. This transportation and storage container for web material for forming an air permeable, endless transport belt comprises: - a substantially closed housing; - a first and a second storage rod positioned inside the housing for holding wound-up

100209NL01 2 web material; - at least one guide roller defining a transport part extending between the first and the second storage rod; - a mounting recess provided in the housing for mounting a web material processing station on the housing; - a first and a second opening provided in the housing at the mounting recess through which openings the transport path extends to outside of the housing.

The guide rollers are positioned such that web material can be wound and/or unwound on and/or from the storage rods. Therein the web material passes through the mounting recess, wherein a processing station can be mounted. The openings are provided at the mounting recess, such that the web material can enter the processing station as soon as it exits the housing. Similarly, the processed web material can go back into the housing directly after leaving the processing station. As exposure of the web material is minimal, the chance of degradation or damage to the web material is small. The container allows for the processing of any desired length of web material with minimum material losses. Thereby the object of the present invention has been achieved.

More specific optional features of the invention are indicated in the dependent claims.

In an embodiment, the container further comprises a rotational support upon which the storage rods are mounted, such that the storage rods are rotatable around a common rotational axis positioned between the storage rods. The storage rods are secured to the rotary support, which is rotatable around the common rotational axis. The common rotational axis is positioned between the storage rods, such that both storage rods revolve in elliptical and/or circular motion around the common rotational axis, when the rotary support is rotated. The rotary support may for example be a disc or wheel, provided at either end of the storage rods. By rotating the rotary support, the storage rods preferably undergo a circular motion, wherein they alternatingly take each other's place or angular position. The common rotational axis is preferably mounted on the housing of the container, such it can rotated from outside of the container, either by hand or by motor.

In an embodiment, the container further comprises two first guide rollers, each positioned aligned with a respective one of the openings, such that a position of the

100209NL01 3 transport path between the openings remains unchanged, regardless of the amount of web material present on the storage rods. The diameter of the wound-up web material on the storage rods changes while winding and unwinding. In consequence, the position of portions of the transport path extending directly from the storage rods changes. On either side of the storage rods the transport path curves around the respective one of the two first guide rollers. These two first guide rollers are in a fixed position with respect to their respective openings, and are preferably adjacent to and/or at the same (height) level as their respective openings. This fixes the transport path extending through the openings, without concern of the amount of wound-up web material on the storage rods.

In consequence, the openings can be narrow since the transport path is accurately fixed at the openings. This also aids during processing as it is not desired that the transport path in the processing station changes during processing.

In an embodiment, the at least one guide roller defines a U-shaped transport path, wherein the legs of the U-shape extend towards respectively the first and a second storage rods and the mounting recess is provided at a central portion of the U-shape.

The transport path is formed as a loop. The storage rods are in a central portion of the box, wherein sufficient space is available for rotating the storage rods to wind up web material.

In an embodiment, the first and a second openings are positioned opposite to one another on opposite sides of the mounting recess. In absence of the processing station, one opening faces the other. A straight or linear transport path is thereby formed between the openings. This external transport path section is defined by the positions of the two first guide rollers and aligned with a transport path section of the processing station when it is mounted in the mounting recess.

In an embodiment, the container further comprises two second guide rollers, such that all guide rollers are positioned in an rectangular configuration. The first and second guide rollers are each positioned at a respective corner of an imaginary rectangle extending inside the housing. The storage rods as well as the mounting recess can thus be centrally positioned in said rectangle. This results in a space-efficient configuration. It will be appreciated that additional guide rollers besides the before mentioned four guide rollers may be applied to form the transport path.

100209NL01 4

In an embodiment, the first and second storage rods are positioned in between the two second guide rollers. The second guide rollers preferably provide a curve or turn in the transport path bending the transport path towards the first guide rollers. The first guide rollers bend the transport path towards and through the openings. The storage rods are positioned in between the second guide rollers, while the mounting recess and/or the openings are positioned between the first guide rollers. This allows for a space efficient configuration, wherein the storage rods and the second guide rollers are located in a first portion {e.g. a first half) of the housing, and the first guide rollers, the openings, and the mounting recess in a second portion (e.g. a second half).

In an embodiment, the mounting recess is positioned over the first and the second storage rods. A compact container is achieved by letting the transport path loop around the guide rollers in their rectangular configuration. The mounting recess is positioned closely to the storage rods, while leaving room for winding up web material. The mounting recess is positioned over the storage rods in a first direction, which may be the vertical direction. The guide rollers allow the web material to extend away from the storage rods and/or through the openings and the mounting recess in a second direction perpendicular to the first. The second direction may be the horizontal direction. Between respective pairs of the first and second guide rollers the transport path extends in the first direction, on either side of the mounting recess.

In an embodiment, the openings are formed as slits in the housing. Exposure of the web material to the ambient is preferably minimized. Thereto the openings are provided as narrow slits with a length at least that of the web material. The width of said slits is preferably kept as small as possible.

In an embodiment, a material of the housing is air tight. The housing, with the possible exception of the openings, is preferably air tight and/or moisture proof. This aids in protecting the web material during transport and storage.

The present invention further relates to a method for forming an air permeable transport belt, comprising the steps of: a) transporting a first length of the web material through at least one of two

100209NL01 openings in a housing of a transportation and storage container via guide rollers to a pair of storage rods and winding up the web material by rotating the pair of storage rods around a common rotational axis; b) mounting a first processing station in a mounting recess on the transportation and 5 storage container; c) unwinding the web material from the pair of storage rods inside the housing of the container via the guide rollers through at least one of the openings to the first processing station, where the web material undergoes a first processing step;

Cc) re-inserting the processed web material into the housing via one of the openings via guide rollers to the pair of storage rods, where the web material is re-wound, followed by: d) removing the first processing station from the mounting recess; e) transporting the container to a second processing station, where the steps b to d are repeated.

The container may be configured as described above and used to transport the web material in between processing steps. Before and/or after every processing step, the web material can be wound-up on the storage rods. The respective processing station is placed in the mounting recess, after which the web material is unwound from the storage rods, via the guide rollers, through the one or more openings, and across the mounting recess. The web material thus passes through the mounted processing station with minimum exposure to the ambient. The processed web material is re-wound onto the storage rods. Thus, an exact length of the web material can be cut and processed without exposure to the ambient. This reduces the risk of damage and degradation of the web material, decreasing the potential loss of web material. After processing, the processing station is removed. The re-wound web material is safely stored inside the housing, allowing it to be stored and/or transported to a further processing station, where the web material can be unwound for further processing and/or testing. This may be repeated until completion of the endless, air permeable belt. In another embodiment, the air permeable belt is then mounted in an inkjet printing system.

The present invention further relates to a printer comprising an air permeable transport belt formed by the above described method.

Further scope of applicability of the present invention will become apparent from the

100209NL01 6 detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the present invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the present invention will become apparent to those skilled in the art from this detailed description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will now be described with reference to the accompanying drawings, wherein the same reference numerals have been used to identify the same or similar elements throughout the several views.

Fig. 1 shows the transportation and storage container 1 for moving web material between processing stations (20 in Fig. 7) and also for storing web material for later processing. The web material is meant for forming an endless transport belt for an inkjet

100209NL01 7 printer. Such belts are used to transport sheets of print media along a printhead assembly. These belts are provided with through-holes and positioned over a suction chamber, which allows an underpressure to be applied to the sheets through the through-holes in the belt. In this particular example, the belt is formed of a plastic material. Using plastics reduces the material costs for such a belt.

The transportation and storage container 1 in Fig. 1 comprises a housing 2. The housing in Fig. 2 is formed as a substantially rectangular box. Inside the housing 2 a pair of storage rods 4, 6 is provided on a rotary support 3. The storage rods 4, 6 are positioned centrally in the housing 2, adjacent to one another, in a lower half of the housing 2. The storage rods 4, 6 are rotatable inside the housing 2 around the common rotational axis 13. The storage rods 4, 6 are intended for winding up or unwinding web material (the winding process will be explained with respect to Figs. 3 to 6). The storage rods 4, 6 are positioned sufficiently remote from the walls of the housing 2 (and other components) to allow a substantial amount of web material to be wound up on the storage rods 4, 6. Each storage rod 4, 6 is further rotatable around its respective rotational axis 5, 7. It will be appreciated that the storage rods 4, 6 may also be rigidly secured to the rotary support 3 in a different embodiment. The rotational axes 5, 7 are provided on the rotary support 3. The rotary support 3 itself is also rotatable around its common rotational axis 13. The common rotational axis 13 of the rotary support 3 is different from the rotational axes 5, 7 of the storage rods 4, 6. The common rotational axis 13 is positioned centrally in between the storage rods 4, 8. In consequence, the rotational axes 5, 7 of the storage rod 4, 6 can be moved along a circular trajectory. By moving through this circular trajectory the storage rods 4, 6 alternate in their positions.

This allows a length of plastic web material to be wound up on the storage rods 4, 6, as will be shown in Figs. 3 to 6. The rotary support 3 is mounted on the housing 2 by means of a suitable bearing, but has a driving element extending outside the housing 2.

A drive motor may be provided to rotate the rotary support 3 by engaging the driving element, though manual driving can also be applied.

Additionally, guide rollers 8-11 are provided inside the housing 2. The guide rollers 8-11 define a transport path P, as indicated in Fig. 2. The transport path P extends from one storage rod 4, 8 to the other via the guide rollers 8-11. Initially, as shown in Fig. 3, the transport path P also extends cross-wise between the storage rods 4, 6. The guide

100209NL01 8 rollers 8-11 thereto define a looping transport path P to supply web material to the storage rods 4, 6 (and/or to unwind it from there). The guide rollers 8-11 are positioned at respective corners of an imaginary rectangle positioned inside the housing 2. The storage rods 4, 6 are positioned centrally or symmetrically in the transport path P.

The first or upper guide rollers 8, 11 align the transport path P with the openings 14, 15 in housing 2. The openings 14, 15 are formed as slits in the housing at the edges of the mounting recess 18. These slits can be very narrow, since the first guide rollers 8, 11 fix the transport path P between them. Regardless of the amount of web material on the storage rods 4, 8, the transport path section between the first guide rollers 8, 11 will not change. This also advantageous as the processing station 20 requires a well defined and unchanging transport path P as well.

The openings 14, 15 are positioned in opposing walls of the mounting recess 18. The mounting recess 18 provides a space for a web material processing station 20, as shown in Fig. 3. The mounting recess 18 is dimensioned to fit the processing station 20.

The mounting recess 18 is positioned between the upper guide rollers 8, 11 in the side view in Figs. 1-3. The openings 14, 15 are positioned such that the transport path P extends as a straight or linear portion through the mounting recess 18. The mounting recess 18 may be provided with mounting or securing means for attaching the processing station 20 to the housing 2. Second guide rollers 9, 10 are provided on opposite sides of the storage rods 4, 6 to extend the transport path P to the respective first guide rollers 8, 11. Each guide roller 8-11 defines a substantially right or 90° turn in the transport path P. This results in a compact configuration wherein the storage rods 4, 6, the openings 14, 15, and the mounting recess 18 are located between respective pairs of guide rollers 8-11.

The processing station 20 may be a (laser) puncher, welding device, cleaning device, measuring device, etc. Generally multiple processing steps are required for processing the web material into an endless transport belt, as well as tests to determine the quality of the belt. To ensure a minimal loss of material when forming such a transport belt, the following method steps are applied. The steps of this method are illustrated in Fig. 8.

In a first step i, a web material W is provided for winding it up on the storages rollers 4,

100209NL01 9 6. The web material W is threaded through the left opening 14 in Fig. 3 via the left guide rollers 8, 9 towards the storage rods 4, 6. The web material W therein crosses in between the storage rods 4, 6. In Fig. 3, the storage rods 4, 6 have been rotated, such that the web material W extends from the top side of one storage rod 4 to the bottom side of the other storage rod 8. From there, the web material W is fed via the right guide rollers 10, 11 to the right opening 15. The web material W extends out of the housing 2 via both openings 14, 15.

In step ii, the web material W is wound up on the storage rods 4, 6 by rotating the rotary support 3. The winding up is illustrated in Figs. 3 to 6. Fig. 3 illustrates the initial path P of the web material W when starting the rotation of the rotary support 3. It will be appreciated that the storage rods 4, 6 can also be positioned vertically above one another to allow the initial web material W to pass in between the storage rods 4, 6 more easily.

In Fig. 4 the rotatory support 3 is rotated half a turn with respect to Fig. 3. The web material W begins to partially wrap around both storage rods 4, 6. In Fig. 5, the rotary support 3 is rotated another half turn as compared to Fig. 4. The outer portions of the web material W now extend from one storage rod 4, 6 to the other. A subsequent half turn, as shown in Fig. 6, wraps a further portion of the web material W around the storage rods 4, 6. By repeating the movement in Figs. 5 and 6, the web material W may be wound up on the storage rods 4, 6 until the free ends of the web material W are positioned at the openings 14, 15.

The web material W is preferably a longitudinal plastic film. While inside the container 1, the web material W can be stored and transported without fear of contamination or material degradation. In step iii, the container with the web material W is transported to a second processing station 20, for example an attachment station, which first processing station 20 is mounted in the mounting recess 18. The attachment station 20 connects the free ends of the web material W to one another, creating an endless web or belt. Such an attachment station may be a welding or adhering station.

In step iv shown in Fig. 7, the first processing station 20 is removed from the mounting recess 18. Next, in step v, the container 1 is transported to a second processing station

100209NL01 10 20 (or the processing station 20 may be brought to the container 1). In step vi, the web material W is unwound from the storage rods 4, 6 and transported via the guide rollers 8, 11 through the openings 14, 15. The web material W thereby passes through the second processing station 20, where the web material W undergoes a second processing step vii, for example the formation of through-holes in the web material W by (laser) punching. During processing the web material W has minimal exposure to the ambient as it enters or exits the container 1 in the direct vicinity of the second processing station 20. After completion of the second processing step, the second processing station 20 is decoupled from the mounting recess 18. Optionally, in case the web material Wis still unwound in the second processing station 20, a step of re- winding the web material W, as in step ii may be performed. Steps iii to vii may be repeated for additional processing of the web material W, for example applying coatings or performing measurements to determine one or properties of the web material W for e.g. quality checks. In a final step, the web material W is removed from the container 1 and mounted as a transport belt in a printer 1.
