Description

DESCRIPTION

Automatic desktop printer for security booklet documents

The present invention relates to desktop printers for security booklet documents and, in particular, to automatic desktop printers, in which the security booklet documents are documents such as p. eg, passports.

There are two categories of printers. A first category refers to manual feed printers. Such printers have good print quality, but are not suitable for industrial needs due to the time it takes to insert the booklet into the printer and remove it.

Such printers are known, for example, from document EP1520715 which describes a passport moving in a shuttle along a Y direction under a printing device that is stopped at least along the Y direction. Consequently, a passport needs to pass under the printing device twice before exiting the printer. Furthermore, the position of the shuttle must be known and controlled very precisely to obtain good print quality. JPH10329376 describes another type of passport printer, which uses rollers or possibly a conveyor belt to transport the passport.

A second category of printers refers to automatic feed printers. Such printers are more suitable for industrial needs and are known, for example, from documents such as US7931270, in which a large number of security documents or smart cards are arranged at an input station and collected in one direction. by means of a shuttle system that can be moved back and forth parallel to the longitudinal axis. The shuttle is designed in such a way that it can feed or withdraw documents from the exit areas of the processing stations by rotating movement or by means of a pusher. As for manual printers, these printers face the problem that the position of the shuttle must be known and controlled very precisely.

Therefore, there are specific printers for printing on security booklet documents, but they are complex, especially their print head assembly, heavy (not desktop) and therefore very expensive.

According to the present domain, Security Booklet 1 documents should be printed on one or two pages only. Both pages must be consecutive and on the same plane, which means that a sheet will not be flipped to print from one page to the other.

A security booklet document 1 comprises a seam 2 at its center.

The security booklet documents 1 are stacked in an input stacker (not shown). Preferably, they are stacked at least partially open on the page or pages to be printed. This avoids the need to implement a page turning mechanism within the printer 10. The security booklet documents 1 are fed from the input stacker to the input of a transport mechanism along the Y axis at a feeding direction. In this case, the security booklet documents are fully opened (180 degrees) through an input hopper (not shown) and pushed into the printer. A sensor inside the printer detects the presence of a security booklet document and automatically activates the conveyors. Thus, they enter the transport mechanism in a substantially flat, open position on the page or pages to be printed. Preferably the seam is parallel to the Y axis.

Transport mechanism

The printer 10 comprises a security booklet document transport mechanism, here after the concise transport mechanism, which allows a security booklet document 1 to move automatically along the Y-axis from an IN input to a OUTPUT output of the printer 10. The input of a security booklet document 1 into the transport mechanism can be detected by a sensor (not shown), typically an optical sensor and, for example, a photocell, or by any other mechanism detection.

The transport mechanism comprises a housing 101 that fits substantially parallelepiped, which simplifies construction of the printer.

Figure 2 is the same view as Figure 1, focusing on the housing 101, that is, where various elements of the printer, such as p. eg, the print bridge, which is described in more detail, has been omitted. As illustrated in Figure 2, the transport mechanism housing 101 comprises, at its entrance, a flat surface 102 on which a security booklet document 1 can slide, in this case a face-up security booklet document 1 and slides on its back.

Preferably, a security booklet document 1 can slide on the flat surface 102 with the help of at least one set of at least one roller 105 that grips said document.

In one embodiment, a single flat surface 102 and a single set of at least one roller 105 can be implemented. In that case, the set of rollers 105 is preferably located above the flat surface 102. In that case, the flat surface it can be smooth. Alternatively, the set of rollers 105 may be located below the flat surface, in which case said flat surface comprises a set of at least one through hole 104, that is, one through hole 104 per roller 105. A roller 105 projects to through its respective through hole 104 to grasp the rear of the security booklet document 1.

In one embodiment, a single flat surface 102 and two sets of at least one roller 105 can be implemented. This embodiment is the same as the previous one, with the second set of at least one roller 105 positioned opposite the first set of at least one roller. roller 105 with reference to the flat surface 102. In this way, the first set of at least one roller 105 can grip the back of the security booklet document 1 and the second set of at least one roller 105 can grip the front (that is, the pages to be printed) of the security booklet document 1.

Preferably, the transport mechanism comprises at its input a first set of at least one roller 105 located on top of the flat surface, and a second set of at least one roller 105 located below the flat surface. The first set and second set of rollers 105 are arranged so that a roller 105 of the first set faces a roller 105 of the second set through a through hole 104 in the flat surface. The rollers 105 are driven by an electric motor (not shown).

Preferably, the first set and the second set each comprise two rollers 105. The position of the rollers 105 is chosen so that each roller 105 faces a page to be printed. Alternatively, only one roller 105 can be used per set and positioned on each side of the seam of the security booklet document 1. Preferably, the rollers 105 located at the top of the flat surface are secured to one end of a spring 112 that applies a vertical force so that said roller or rollers can grasp a security booklet document 1 (see figure 8) .

The axis of rotation of the rollers 105, called the X axis, is perpendicular to the direction of the Y axis, as illustrated in Figure 3, which represents a front view of the inlet of the printer illustrated in Figure 2, seen slightly from above.

The rollers 105 of the first set and the rollers 105 of the second set rotate in opposite directions. A roller 105 is designed to be in contact with the security booklet document 1 through a respective through hole 104. When activated, a roller 105 grips the security booklet document 1 and its rotation causes the security booklet document 1 to slide along the Y-axis on the flat surface 102.

Accordingly, the flat surface preferably comprises at least one through hole 104. The first set of rollers 105 is located above the flat surface and the second set of rollers 105 is located below the flat surface. A roller 105 of the second set is capable of being in contact with the back of a security booklet document 1 to be printed through said set of at least one through hole 104.

In one embodiment, the printer 10 comprises a second flat surface 103, which advantageously also comprises a set of at least one through hole 104, that is, one through hole 104 per roller 105. The first set of rollers 105 is located above the second flat surface 103. One of the rollers 105 of the first set projects into a corresponding through hole 104 of the second flat surface 103 and is capable of being in contact with the page of a security booklet document 1 to be printed through said set of at least one through hole 104.

The flat surface 102 and the second flat surface 103 are advantageously similar in shape and size, but not parallel, and have a cross section that is V-shaped to facilitate the entry of a security booklet document 1 on the conveyor belts described below. continuation.

The transport mechanism comprises a first conveyor belt 106 and a second conveyor belt 107, positioned downstream of the rollers 105 in the direction of the Y axis. Each belt is elongated along the direction of the Y axis, and is positioned so that a security booklet document 1 slides from the flat surface on top of the conveyor belts, each belt being positioned on a respective side of the security booklet document 1. The first conveyor 106 and a second conveyor 107 are driven by a motor 111, preferably a shared motor for both belts.

Preferably, the conveyor belts each comprise a set of (longitudinal) stops or indices 108. The distance between two consecutive stops 108 is preferably equal to or slightly greater than the length of the security booklet document 1, and the distance between the two conveyor belts is substantially equal to the width of the security booklet document 1. By "slightly greater than" is strictly meant greater than a predetermined value.

Preferably, the transport mechanism comprises a first deck rail 109 and a second deck rail 110, each deck rail positioned above a respective conveyor belt and preferably having an L, C, or U-shaped cross section. Each rail Covering comprises a flat part, or lip, parallel to the direction of the Y axis, and configured to cover a lateral edge of the security booklet document 1 when said security booklet document 1 slides inside the transport mechanism on the conveyor belts. .

A printable page of a security booklet document 1 comprises a printable part located at its periphery. Preferably, the width of each lip is chosen to be less than or equal to the width of said non-printable portion.

Since the back of the security booklet document 1 is held both by the flat surface of the transport mechanism and by the conveyor belts, and its side edges are held below the cover rails, the security booklet document 1 it remains substantially flat during transport within the transport mechanism.

The rotation of the conveyor belts moves the security booklet document 1 from the entrance of the transport mechanism to its exit, through a flattening mechanism.

Flattening mechanism

A security booklet document 1 comprises several pages secured together along a seam, dividing the booklet into two sides. Because the pages to be printed are generally among the top of the booklet, when a security booklet document 1 is open on these pages, one side of the security booklet document 1 is normally thicker than the other.

A flattening mechanism is designed to be positioned underneath a security booklet document 1 to compensate for this difference in thickness so that both pages to be printed are substantially in the same horizontal plane.

Preferably, the flattening mechanism is stopped, secured to frame 11, and independent of the movement of the print bridge.

Alternatively, the flattening mechanism can be integral in translation with the impression bridge, but the construction is then more complex.

The flattening mechanism is located between the conveyor belts and comprises two pistons; a first piston 201 and a second piston 202. Each piston comprises a flat surface that can move vertically between an up position and a down position, and whose height is adjustable, in this case with a piston drive 204 and a spring 205 (figure 7 and figure 8). Figure 7 illustrates an enlarged view of the inlet of the printer of Figure 6 where the first flat surface 102, the second flat surface 103 and the first set of rollers located in the The upper portion of the second flat surface 103 has been omitted to better illustrate the conveyor belt 106. and its stops 108 within the housing 101.

The flat surface of a piston that contacts the back of the security booklet document 1 is designed to conform to the design of that security booklet document 1 and acts as a support for one side of the booklet.

The flattening mechanism has two sensors (not shown): one for the up position of the piston and one for the down position of the piston. These position sensors are in this case optical sensors. These two sensors control the piston drive 204. Both pistons, also called flatteners, are elastically loaded with a spring 205 to compensate for the thickness of the security booklet document.

Advantageously, the flattening mechanism can be activated by the mere position of the printing bridge or, as is the case here, by the position of the security booklet document on the conveyor belt 106, which is detected by a position sensor, in this case a Optical sensor (not shown) that detects the position of the security booklet document and stops the forward movement of the conveyor 106.

At the input of the printer 10, the back of a security booklet document 1 is in contact with both the conveyor belts and the flat surface. When the printer 10 is operated, the conveyor belts drag the security booklet document 1 which slides along the flat surface from the entrance of the printer 10 to the top of the flattening mechanism pistons where it reaches a position of impression. The conveyor belts are then stopped so that the security booklet document 1 remains in a stationary position for the printing operation.

Preferably, the transport mechanism comprises, at its entrance, a flat cover which is placed on the flat surface on which the security booklet document 1 is placed, in such a way that at least a part of a booklet document 1 of Safety that lies on the flat surface is covered by the flat cover.

Here, the flat cover is the second flat surface 103 described hereinabove.

The flat cover has a straight edge that is perpendicular to the Y-axis direction, and is designed to cover at least part of the non-printable area of a security booklet document 1.

Preferably, the flat cover allows a security booklet document 1 to slide underneath.

Preferably, the flattening mechanism also comprises a skirt 203, which is located opposite the straight edge of the flat roof and at approximately the same height, and has a straight edge that is perpendicular to the direction of the Y axis.

The skirt 203 can be moved in a translational or rotational movement between a rest position and the printing position where the printing operation described here below can occur.

In the rest position, the skirt 203 is open and the security booklet document 1 is conveyed under the skirt 203 by the conveyor belts.

In the printing position, the skirt 203 is operated in its closed position to cover the unprintable portion of a booklet edge.

Assuming that a security booklet document 1 is fed into the printer 10 with its seam parallel to the Y axis, and its top first, then the straight edge of the flat cover covers the unprintable bottom of the pages that are to be printed, the cover rails cover the non-printable side edges of the booklet, and the skirt 203 covers the non-printable top of the pages to be printed.

The two pistons of the flattening mechanism exert an upward force, and the straight edge of the flat roof, the cover rails, and the skirt cover 203 exert a downward force, acting as vertical stops.

Next, the booklet is held in a stationary position, called the printing position, for the printing operation which is operated with the aid of a printing bridge 301.

Impression bridge

Frame 11 also supports at least one print bridge 301, comprising a print head 315 and a set of at least one ink cartridge 302 (see Figure 5).

The printing bridge 301 comprises a pair of sliding elements, each sliding element 303 being designed to slide along a respective guide rail of the bridge, the shape of each sliding element 303 cooperating with the shape of its respective guide rail, the guide rails extend in a direction parallel to the Y axis.

Consequently, the printing bridge 301 can be moved on the security booklet document 1 longitudinally along the Y axis thanks to a pair of guide rails; that is, a first bridge guide rail 304 and a second bridge guide rail 305. Movement along the Y axis is controlled by a first sprocket 311 cooperating with a sprocket rail 312 as described below.

A track 306 having one end secured to the frame 11 and another end secured to the bridge allows to cover the electronic cables coming from the print bridge down to the electronic boards that are located within the frame of the printer. In this way, the electrical cables are protected, sheathed, when the printing bridge moves along the Y-axis. Preferably, the end of the track 306 that is secured to the bridge is secured to the top of a side flank 307 of the bridge, said track 306 being outside the bridge.

The print bridge 301 may comprise a shaft 308 of the print bridge 301 on which the print head is mounted and along which it can slide in both directions. The shaft 308 of the print bridge 301 is oriented in an X-axis direction, perpendicular to the Y-axis direction. The length of the bridge shaft is greater than or equal to the width of a security booklet document 1.

The printing bridge 301 may comprise a first housing 309, which is secured to an edge of the printing shaft and comprising a sliding member 303 that can slide along a guide rail of the frame 11. The first housing 309 comprises circuitry electronics for the print head. Preferably, the movable print head also remains in an opening of the first housing while it is in the home position, that is, it is not in use.

The printing bridge 301 may comprise a second housing 310 which is fixed to the other edge of the printing shaft and comprising another sliding element 303 which can slide along the other guide rail of the frame 11. The second housing 310 comprises an assembly of at least one first sprocket 311, which is mounted on a drive shaft 313.

The first sprocket is designed to cooperate with a toothed rail 312 that is secured to the casing 101 and which is parallel to the direction of the Y axis. Consequently, the movement of the casing 101 along the Y axis causes the casing to rotate. first sprocket.

Advantageously, the drive shaft comprises a coding disk 314 on the opposite side of the first sprocket, said coding disk allowing to locate the actual position of the print head along the Y axis.

Furthermore, the second housing 101 may comprise a set of toothed wheels, possibly gears and an electric motor, configured to drive the movement of the pistons of the flattening mechanism, acting as an eccentric drive.

Figure 5 illustrates the printer of Figure 1 viewed from its left side, and Figure 4 illustrates the printer of Figure 5 where the print bridge has been omitted. Similarly, Figure 6 illustrates the printer of Figure 5 where various components of the print bridge have been omitted, to better illustrate the first sprocket 311, the sprocket rail 312, and the encoder disk 314.

As can be seen in Figure 4 or Figure 5, an electric motor (not shown) rotates the drive shaft 313 and the first sprocket 311, which is rotationally connected to the drive shaft 313. Because the toothed rail 312 cooperates with the first sprocket 311 and is secured to the printing bridge 301, the rotation of the first sprocket 311 about the X axis drives the printing bridge 301 to move along the first and second rails 304, 305 guide of the bridge along the Y-axis direction. Since the coding disk 314 is fixed in rotation to the first sprocket 311, the position of the printing bridge 311 along the Y-axis is known.

In this way, it is also possible to use the simple position of the printing bridge 301 along the Y axis to activate a position of the pistons of the flattening mechanism, through actuation of the piston or pistons.

In another embodiment, the print bridge 301 may comprise a stationary print head as long as said print head is wide enough to cover the booklet page or pages to be printed.

Print operation

For the printing operation, the printing bridge 301 moves along the Y axis between a start position and an end position.

In the printing operation, the security booklet document 1 is held in a stationary position along the Y axis, typically stopping the rotation of the conveyor belts.

The pistons of the flattening mechanism are held in their upward position so that the pages of the security booklet document 1 to be printed offer a flat horizontal surface.

The skirt 203 is actuated in its closed position and the cover rails also act as stops against the vertical pressure of the pistons.

In this way, the security booklet document 1 is held in a stationary position both vertically and horizontally.

For printing to occur, the bridge moves along the Y-axis direction thanks to the first sprocket 311 as described above, and the print head moves along the X-axis direction to print. on the pages of document 1 of the safety booklet.

After printing is complete, the final position of the bridge is sensed by the encoder disk which in turn releases the pistons from the flattening mechanism, driving them to their down position and the skirt 203 is operated to open.

Preferably, after the printing operation is completed, the bridge returns to its initial position, the clamping device is opened and the booklet is transported to another side (the rear) of the printer 10, through the same transport means. Consequently, the conveyor belts are activated to move the security booklet document 1 along the Y-axis in the feeding direction. In this way, the security booklet document 1 can exit the printing bridge 301 away from the input stacker.

The security booklet document 1 can then be transported with the aid of the conveyor belts along the Y-axis direction to another area.

Frame 11 can support a second print bridge 301 in another area. The second bridge may be similar to the first bridge described above, located along the same guide rails or along a second pair of guide rails that are collinear to the first pair of guide rails described above.

At least one of the first print bridge 301 and the second print bridge may comprise a set of marking heads. By "marking head" is meant a device whose use marks the security booklet document 1 by locally altering its structure and comprising, for example:

- needles for micro perforation,

- a laser engraving device (where the heat from the laser is used to burn certain information onto plastic, metal or treated paper of the security booklet document),

- a laser ablation device (where the laser is used to produce certain additional personalization information, such as a photo micro-perforation in the security booklet document), or

- a thermal sublimation device.

One of the first printing bridge 301 and the second printing bridge may also comprise a set of at least one ink cartridge 302, said ink cartridge or cartridges being different from the ink cartridge or cartridges of the other of the first printing bridge 301 and of the second impression bridge. For example, the first print bridge 301 may support visible ink cartridge (s) and the second print bridge 301 may support non-visible ink cartridge (s) or needles.

For example, the first bridge comprises a first set of cartridges comprising visible inks (cyan, yellow, magenta, and black), and the second bridge comprises a second set of cartridges comprising invisible ink (eg, UV ink) or needles, etc.

Both the first and second bridges are configured to print serially on the same booklet pages, the bridge being advantageously independent of the second printer 10 from the first bridge.

In one embodiment, both the first and second jumpers are comprised of a printer 10. Alternatively, the first bridge is comprised of a first printer 10, and the second bridge is comprised of a second printer 10, working in series with the first. printer 10.

Printer 10 comprises two electronic circuits.
