This Application is Section 371 National Stage Application of International Application No. PCT/IB2015/053496, filed May 12, 2015 and published as WO 2016/181190 A1 on Nov. 17, 2016, in English, the contents of which are hereby incorporated by reference in their entirety.
Credentials include identification cards, driver's licenses, passports, and other documents. Such credentials are formed from credential or card substrates including paper substrates, plastic substrates, cards, and other materials. Such credentials generally include printed information, such as a photo, account numbers, identification numbers, and other personal information. Credentials can also include data that is encoded in a smartcard chip, a magnetic stripe, or a barcode, for example.
Credential production devices include processing devices that process credential substrates by performing at least one processing step in forming a final credential product. Such processes generally include a printing process, a laminating or transfer process, a data reading process, a data writing process, and/or other process used to form the desired credential.
In a printing process, a printing device is used to print an image either directly to the substrate (i.e., direct printing process) or to a print intermediate, from which the image is transferred to the substrate (i.e., reverse-image transfer printing process). Typical printing devices include a thermal print head, which prints an image by heating and transferring dye from a print ribbon, and an ink jet print head.
In a transfer or laminating process, an overlaminate material is transferred to a surface of the card substrate using a heated laminating or transfer roller. The material may be in the form of a patch laminate or a thin film laminate. The overlaminate material is typically one of two types: a patch laminate, or a fracturable laminate or transfer layer often referred to as a “thin film laminate.” The patch laminate is generally a pre-cut polyester film that has been coated with a thermal adhesive on one side. The transfer roller is used to heat the patch to activate the adhesive, and press the adhesive-coated side of the patch to a surface of a substrate to bond the patch to the surface.
Thin film laminates or transfer layers are fracturable laminates that are generally formed of a continuous resinous material that have been coated onto a continuous carrier layer or backing to form a transfer ribbon. The side of the resin material that is not attached to the continuous carrier layer is generally coated with a thermal adhesive which is used to create a bond between the resin and a surface of a substrate. The transfer roller is used to heat the transfer layer to activate the adhesive and press the adhesive-coated side of the transfer layer against the surface of the substrate to bond the material to the surface. The carrier layer or backing is removed to complete the lamination or transfer process.
The transfer layer or patch laminate may also be in the form of a print intermediate, on which an image may be printed in the reverse-image printing process mentioned above. In the reverse-image printing process, an image is printed to the exposed side of the transfer layer or patch laminate. Next, the printed image is registered with the substrate. The transfer roller is then used to perform the transfer or laminating operation described above to bond the transfer layer or patch laminate having the printed image to the surface of the card substrate.
Transfer printing devices generally require the loading of the print ribbon and the transfer ribbon (or a patch laminate ribbon) in the device, such that the print ribbon and the transfer ribbon are positioned for processing by the print head. Additionally, the transfer ribbon must be positioned for processing by the transfer roller. These ribbon loading processes can require the user to delicately feed the print and transfer ribbons through openings, around rollers, and attach an end of the ribbons to a corresponding take-up spool, for example. These ribbon loading processes may also require temporary displacement of one or more components relative to the installed ribbon, which can adversely affect operations of the transfer printing device.
Some embodiments of the invention are directed to a credential production device that is configured to perform at least one process on a substrate to form a credential product. In some embodiments, the credential production device includes a processing path, a transport mechanism, a processing assembly, and at least one assembly guide. The transport mechanism is configured to feed individual substrates along the processing path in a feed direction. The processing assembly includes a supply spool support, a take-up spool support, a plurality of ribbon supports, and a print head or a transfer roller. Each assembly guide is configured to guide movement of the processing assembly substantially perpendicularly to the processing path between an operating position and a loading position relative to the processing path.
In some embodiments, the processing assembly is cantilevered by the at least one assembly guide when the processing assembly is in the loading position. In some embodiments, the credential production device includes a main frame having a fixed position relative to the processing path, and each assembly guide includes a first guide member that is attached to the main frame, and a second guide member that is attached to the processing assembly and engages the first guide member. The second guide member and the processing assembly move between the loading and operating positions relative to the main frame and the first guide member. In some embodiments, the first guide member includes a channel that receives an end of the second guide member, and the second guide member slides within the channel of the first guide member as the processing assembly moves between the loading and operating positions.
In some embodiments, the processing assembly includes at least one motor. In some embodiments, the processing assembly includes a supply spool motor configured to rotate the supply spool support, a take-up spool motor configured to rotate the take-up spool support, a feed motor configured to drive rotation of a feed roller, a transfer roller motor configured to drive rotation of the transfer roller, a transfer roller lift motor configured to move an axis rotation of the transfer roller relative to a frame of the processing assembly, and/or a print head lift motor configured to move the print head relative to the frame of the processing assembly.
In some embodiments, the processing assembly is a transfer assembly comprising the transfer roller, which is configured to transfer a section of overlaminate material from a transfer ribbon extending between a supply spool supported by the supply spool support and a take-up spool supported by the take-up spool support to a substrate in the processing path when the transfer assembly is in the operating position. In some embodiments, the overlaminate material comprises a transfer layer or an overlaminate patch.
In some embodiments, the processing assembly is a print assembly comprising the print head, which is configured to print an image using a print ribbon extending between a supply spool supported by the supply spool support and a take-up spool supported by the take-up spool support when the print assembly is in the operating position.
In some embodiments, the credential production device includes both a transfer assembly and a print assembly, and the print assembly is configured to print an image to an overlaminate material of the transfer ribbon. The transfer assembly is configured to perform a transfer lamination operation, during which the imaged overlaminate material is transferred to a surface of a substrate in the processing path.

In some embodiments, the device 100 includes a processing path 104, a transport mechanism 106, and a substrate supply 108. The substrate supply 108 may be in the form of a container or cartridge that is configured to contain individual substrates 110. The substrates 110 are individually fed from the supply 108 along the processing path 104 in a feed direction 111, which is parallel to the processing path 104, for processing using the transport mechanism 106, which is controlled by the controller 102. In some embodiments, the transport mechanism 106 includes one or more motorized feed rollers or feed roller pairs 112, or other suitable mechanism. Sensors may be used to assist the controller 102 in the feeding of the substrates 110 along the processing path 104, and aligning the substrates 110 with substrate processing devices along the processing path 104.
The substrates 110 may take on many different forms, as understood by those skilled in the art. In some embodiments, the substrate 110 is a credential substrate. As used herein, the term “credential substrate” includes substrates used to form credentials, such as identification cards, membership cards, proximity cards, driver's licenses, passports, credit and debit cards, and other credentials or similar products. Exemplary card substrates include paper substrates other than traditional paper sheets used in copiers or paper sheet printers, plastic substrates, rigid and semi-rigid card substrates, and other similar substrates.
In some embodiments, the device 100 includes at least one processing assembly, generally referred to as 120. In some embodiments, the at least one processing assembly 120 includes an assembly 120A and/or an assembly 120B. While embodiments described herein may refer to both processing assemblies 120A and 120B, it is understood that such embodiments may apply to only a single processing assembly 120 of the device 100.
In some embodiments, each processing assembly 120 includes a supply spool support 122 (e.g., 122A, 122B), a take-up spool support 124 (e.g., 124A, 124B), and a plurality of ribbon supports 126 (e.g., 126A, 126B) that define a ribbon path 128 (e.g., 128A, 128B) on which a ribbon 129 (e.g., 129A, 129B) is supported. In some embodiments, the ribbons 129A and 129B each extend between a supply spool 130A and 130B to a take-up spool 131A and 131B, respectively. In some embodiments, the supply spool supports 122A and 122B are respectively configured to support the supply spools 130A and 130B, and the take-up spool supports 124A and 124B are respectively configured to support the take-up spools 131A and 131B, as shown in
In some embodiments, each of the processing assemblies 120 include an assembly guide 132 (e.g. 132A, 132B), which is schematically illustrated in
In some embodiments, each processing assembly 120 is cantilevered by the corresponding assembly guide 132 when the processing assembly 120 is in the loading position 136, as shown in the simplified side view of
In some embodiments, the cantilevered loading position 136 of each transfer assembly 120 allows for substantially unencumbered loading and unloading of the ribbon 129 in the assembly 120. In some embodiments, the supply spool support 122, the take-up spool support 124, the ribbon supports 126, and the ribbon path 128 are accessible for loading or unloading the ribbon 129 when the transfer assembly 120 is in the loading position 136, as generally shown in
In some embodiments, the ribbon 129 is installed in the processing assembly by first securing the supply spool 130 or the take-up spool 131 to the corresponding support 122 or 124. The ribbon 129 is then laid over the ribbon supports 126, and the non-secured spool 130 or 131 is then installed on the corresponding support 122 or 124 to complete the loading of the ribbon 129. In some embodiments, it is not necessary to feed the ribbon 129 through an opening when the processing assembly 120 is in the loading position 136. That is, a user is able to wrap the ribbon 129 around the corresponding ribbon supports 126 in one motion without having to feed the ribbon 129 through an opening due to the exposure of the ribbon path 128 while the assembly 120 is in the cantilevered loading position 136. The processing assembly 120 can then be moved back to the operating position 134 using the assembly guide 132 to allow a credential production process to be performed using the ribbon 129.

In some embodiments, the transfer assembly 120A is configured to perform a transfer operation using the ribbon 129A, during which a section of overlaminate material is transferred from the transfer ribbon 129A to a surface 150 of a substrate 110, when the transfer assembly 120A is in the operating position 134A. In some embodiments, the transfer assembly 120A includes a transfer roller 152, which heats and presses the section of overlaminate material against the surface 150 during a transfer operation while the substrate 110 is fed along the processing path 104, as illustrated in phantom lines in
In some embodiments, the section of overlaminate material is in the form of a transfer layer or an overlaminate patch.
In some embodiments, the transfer layer 154 includes a protective layer 164 located between the adhesive layer 158 and the carrier layer 156. Alternatively, the protective layer 164 may be combined with the adhesive layer 158. The protective layer 164 operates to provide protection to the surface 150 of the substrate 110 to which the transfer layer 154 is laminated. The protective layer 164 may also protect an image printed on the image receptive surface 160 when the transfer layer 154 is laminated to a surface 150 of a substrate 110. Other conventional materials or layers may also be included in the transfer ribbon 129A and the transfer layer 154.
As mentioned above, the transfer ribbon 129A may also comprise an overlaminate material in the form of an overlaminate patch, which can be transferred to the surface 150 of a substrate 110 during a transfer lamination operation using the transfer assembly 120A.
In some embodiments, the transfer assembly 120A includes a transfer roller lift mechanism 172 that is configured to move the transfer roller 152 relative to the processing path 104 between a retracted position (solid lines) and a laminating position (phantom lines), as indicated by arrow 174 in
As discussed below, this transfer operation may occur after an image is printed to an image receptive surface of the overlaminate material, such as to the surface 160 (
In some embodiments, the transfer assembly 120A includes one or more motors 178, as shown in
In some embodiments, the transfer assembly 120A includes a transfer roller lift motor 178B that is configured to move the transfer roller 152 and its axis of rotation 180 relative to the processing path 104, as indicated by arrow 174.
In some embodiments, the transfer assembly 120A includes one or more feed rollers 182, which are configured to drive the feeding of the transfer ribbon 129A along the ribbon path 128A. In some embodiments, the transfer assembly 120A includes a feed motor 178C that is configured to drive rotation of each feed roller 182.
In some embodiments, the transfer assembly 120A includes a platen roller 184 and a motor 178D that is configured to drive rotation of the platen roller 184.
In some embodiments, the transfer assembly 120A includes a supply spool motor 178E that is configured to control the feeding of the transfer ribbon 129A along the ribbon path 128A, and the winding and unwinding of the transfer ribbon 129A on the supply spool 130A. In some embodiments, the transfer assembly 120A includes a take-up spool motor 178F that is configured to drive rotation of the take-up spool support 124A, to control the feeding of the transfer ribbon 129A along the ribbon path 128A and the winding and unwinding of the transfer ribbon 129A on the take-up spool 131A.
In some embodiments, the transfer assembly 120A includes gears or other mechanisms that are disengaged from corresponding motorized gears or mechanisms supported by the frame 140 when the transfer assembly 120A is in the loading position 136A, and engage the corresponding motorized gears or mechanisms supported by the frame 140 when the transfer assembly 120A is in the operating position. In some embodiments, the gears of the transfer assembly 120A allow motors that are not supported by the transfer assembly 120A to drive one or more components of the transfer assembly 120A described above, such as the transfer roller 152, the feed rollers 182, the supply spool 130A or the supply spool support 122A, the take-up spool 131A or the take-up spool support 124A, the lift mechanism 172, and/or the platen roller 184, for example.
As mentioned above, in some embodiments, the credential production device 100 is configured to print an image to the overlaminate material before the overlaminate material is bonded to the surface 150 of the substrate 110 during a transfer lamination operation. In some embodiments, the processing assembly 120B is in the form of a print assembly, and the ribbon 129B is in the form of a print ribbon. In some embodiments, the print assembly 120B includes a print head 190 that is configured to print an image to the overlaminate material of the transfer ribbon 129A using the print ribbon 129B, as indicated in phantom lines in
In some embodiments, the print ribbon 129B is in the form of a thermal print ribbon, and the print head 190 is a conventional thermal print head that includes a plurality of heating elements. In some embodiments, the print assembly 120B includes at least a pair of ribbon supports 126B that are configured to support the print ribbon 129B for engagement with the print head 190 when the print assembly 120B is in the operating position 134B, as shown in
In some embodiments, the print assembly 120B utilizes an ink jet print head 190, which applies ink to the transfer ribbon 129A to produce a desired image on the overlaminate material. In this case, the print ribbon 129B, the supply spool 130B, the take-up spool 131B, and other ribbon supporting components of the print assembly 120B can be eliminated from the print assembly 120B shown in
In some embodiments, the print assembly 120B includes a print head lift mechanism 192 that is configured to move the print head 190 between a retracted position, in which the print head 190 does not press the print ribbon 129B against the transfer ribbon 129A supported by the platen roller 184, and a print position, in which the print head 190 presses the print ribbon 129B against the transfer ribbon 129A under the support of the platen roller 184, as indicated in phantom lines in
In some embodiments, the print assembly 120B includes one or more motors 194. In some embodiments, the print assembly 120B includes a motor 194A that is configured to drive the print head lift mechanism 192 to move the print head 190 between the retracted and print positions. In some embodiments, the print assembly 120B includes a supply spool motor 194B that is configured to drive rotation of the supply spool support 122B, and control the feeding of the print ribbon 129B along the ribbon path 128B, the winding of the print ribbon 129B on the supply spool 130B, and/or the unwinding of the print ribbon 129B from the supply spool 130B. In some embodiments, the print assembly 120B includes a take-up spool motor 194C that is configured to drive rotation of the take-up spool support 124B to control the feeding of the print ribbon 129B along the ribbon path 128B, the winding of the print ribbon 129B on the take-up spool 131B, and/or the unwinding of the print ribbon 129B from the take-up spool 131B.
In some embodiments, the print assembly 120B includes gears or other mechanisms that are disengaged from corresponding motorized gears or mechanisms supported by the frame 140 when the print assembly 120B is in the loading position 136B, and engage the corresponding motorized gears or mechanisms supported by the frame 140 when the print assembly 120B is in the operating position. In some embodiments, the gears of the print assembly 120B allow motors that are not supported by the print assembly 120B to drive one or more components of the print assembly 120B described above, such as the supply spool 130B or the supply spool support 122B, the take-up spool 131B or the take-up spool support 124B, and/or the print head lift mechanism 192, for example.
During a print operation, the print assembly 120B is moved to the operating position 134B using the assembly guide 132B. In some embodiments, the transfer assembly 120A is also moved to the operating position 134A using the assembly guide 132A. In some embodiments, the transfer ribbon 129A is fed along the transfer ribbon path 128A to align a desired section of the overlaminate material (transfer layer 154 or overlaminate patch 166) in position relative to the print platen 184 and the print head 190 using conventional techniques. In some embodiments, the print head 190 is moved from the retracted position to the print position using the print head lift mechanism 192, such that the print head 190 presses the print ribbon 129B against the transfer ribbon 129A, which is supported by the print platen 184. The print head selectively transfers print material from the print ribbon 129B to the overlaminate material of the transfer ribbon 129A using conventional techniques to form an image on the overlaminate material. In some embodiments, following the print operation, the print head 190 is moved to the retracted position using the print head lift mechanism 192.
The imaged overlaminate material or section of the transfer ribbon 129A is then fed to the transfer roller 152 by driving rotation of one or more feed rollers 182, the supply spool 130A, and/or the take-up spool 131A using the corresponding motors 178. In some embodiments, the transfer roller 152 is moved from the retracted position to the laminating position using the transfer roller lift mechanism 172. With the imaged overlaminate material of the transfer ribbon 129A aligned with the surface 150 of the substrate 110, the transfer roller 152 commences a transfer lamination operation, in which the transfer roller heats and presses the imaged overlaminate material against the surface 150 as the substrate 110 is fed along the processing path 104 using the transport mechanism 106. This bonds the imaged overlaminate material to the surface 150. The backing or carrier layer 156 is then removed from the transferred imaged overlaminate material to complete the transfer lamination operation. Following the transfer operation, the surface 150 includes the image, which is protected by the overlaminate material.
In some embodiments, the device 100 includes an accumulator 196. The accumulator 196 is configured to take up slack in the ribbon 129A during transfer and/or print operations, as indicated in phantom lines.
The credential production device 100 may include additional substrate processing devices, such as card rotators, a magnetic stripe reader/writer, a data encoder, or other substrate processing device, which can perform additional processes on the substrate 110. Such processing devices may be included in the at least one processing assembly 120. Once the processing of the substrate 110 is completed, the processed substrate 110 may be discharged from the device 100 into an appropriate bin, for example.
In some embodiments, each processing assembly includes at least one assembly guide 132. For example, in some embodiments, the transfer assembly 120A includes assembly guides 132A-1 and 132A-2, as shown in
In some embodiments, each assembly guide 132 includes a guide member 200, which is attached to the frame 140 of the device 100, as shown in
In some embodiments, the assembly guide 132 includes a member 202, which is attached to the processing assembly 120, such as a frame 203 (e.g., sidewalls) of the processing assembly 120, as shown in
In some embodiments, the guide member 202 is configured to move relative to the guide member 200 as indicated by arrow 204 in
In operation, a user can transition a processing assembly 120 from the operating position 134 to the loading position 136 by pulling the processing assembly 120 along the axes 206 of the guide members 200. Thus, the transfer assembly 120A can be transitioned from the operating position 134A (
Embodiments of the device 100 provide advantages over conventional credential production devices. For instance, the inclusion of motors (e.g., 178 and 194), processing devices (e.g., transfer roller 152, print head 190), ribbon supports 126, supply spool supports (122), and/or take-up spool supports (124) in the movable processing assembly 120 allows the relative positions of the components to be accurately maintained over numerous ribbon loading and unloading cycles. As a result, accurate alignment between the components can be maintained while facilitating simplified loading of a ribbon 129 (transfer ribbon 129A or print ribbon 129B) in the device 100. On a design point of view, in some embodiments of the device 100, each processing assembly will look like a modular drawer which can be pulled in and out of the main production device frame, to be loaded with ribbons, repaired, replaced, upgraded, etc. Embodiments of the credential production device 100 described herein also provide other advantages and benefits over conventional credential production devices.
Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
