Description

Technical Field

[0001] The present invention relates to a print roller for a printer for printing marking profiles, a printer having such a print roller, an arrangement structure including such a printer, and a method for manufacturing the print roller. Background Technology

[0002] To print on printing media, a print roller is typically used. This roller feeds the printing media, such as paper, to the print head and optionally presses it against the print head. For printing media such as paper, forward feeding is relatively easy due to the rubberization of the print roller.

[0003] A printer having a print roller for paper is described in U.S. Patent document US 2008 / 089732 A1. This print roller has fine particles to improve paper transport.

[0004] When it is necessary to transport printing media that are large in space and / or relatively rigid compared to paper, the transport process is usually more complicated and the printing cylinders are more prone to wear.

[0005] WO 2018 / 189066 A1 describes a printer for printing marking tapes, wherein the printer has a rotatably supported feed shaft and a print head that can be driven by a motor. In this configuration, the rotatably supported feed shaft has at least one section with serrated teeth that directly abuts against the marking tape as the feed shaft rotates, thereby synchronizing the forward speed of the marking tape with the circumferential speed of the feed shaft. However, this printer is complex to manufacture and requires high clamping force to achieve satisfactory delivery. Excessive pressure may leave permanent and visible indentations on the marking tape, thus reducing the quality of the final result. Adjusting the pressure to achieve satisfactory results is often difficult for users, as this often requires frequent ribbon changes. Therefore, this can ultimately lead to unsatisfactory print results.

[0006] Other printers are described in US 4,780,729 A and WO 2019 / 238492 A1. Summary of the Invention

[0007] The purpose of this invention is to improve the conveying of marking profiles for printing marking profiles.

[0008] This objective is achieved by a subject having the features described in claim 1.

[0009] Therefore, a printer roller for printing marking profiles includes a shaft, at least one support section supported on the shaft, and a transport section arranged adjacent to the at least one support section and rotatably fixedly connected to the shaft for propelling the marking profile by rotation of the shaft, wherein, based on a rotation axis defined by the shaft, the transport section retracts radially relative to the at least one support section to form a receiving portion for the marking profile, wherein the transport section is formed of a substrate on which a friction-enhancing coating is applied.

[0010] This is based on the idea that materials that impart high durability to the conveyor section, such as steel or aluminum, typically have lower friction than materials commonly used for marking tapes, such as plastics like PA, PC, or PE. Therefore, even toothed structures require significant pressure to achieve reliable propulsion. This problem can be easily solved by employing a coating that increases friction with the marking profile material relative to the base material, resulting in a particularly reliable and easily adjustable conveying performance because it provides different properties for the component structure and the contact with the marking profile. This printing roller also enables a particularly robust and durable implementation. This improves the conveying of marking profiles intended for printing markings.

[0011] The coating selectively includes corundum, carbides, particularly tungsten carbide, and / or diamond, or is composed of the above materials. These materials exhibit extremely high durability and enable exceptionally superior transport performance.

[0012] Selectively, the coating material (or one of them) has a Mohs hardness of 6 or higher, 7 or higher, especially 8 or higher, especially 9 or higher. This also enables particularly good conveying performance.

[0013] For example, the particle size of the coating is 0.1 mm to 0.5 mm or 0.7 mm, particularly 0.1 mm to 0.25 mm. This not only effectively avoids the formation of visible indentations but also achieves excellent frictional properties with the marking profile.

[0014] Optionally, the coating can be bonded to the substrate, for example, by resin or similar materials. Alternatively or supplementarily, the coating can be introduced into the substrate material and anchored thereto, for example, in this manner. A particularly effective anchoring method is electroplating. A nickel layer can be deposited here. The coating particles can be coated with the nickel layer. Furthermore, the coating can be applied by flame spraying. Further still, the coating can be applied by chemical vapor deposition (CVD), in which carbon atoms in a gas, for example, are deposited on the tool surface in the form of diamond grains.

[0015] The support section of at least one of these sections may have a carrier and a ring surrounding the carrier. The carrier is rotatably supported on a shaft, for example, and / or the ring is rotatably supported on the carrier. This protects the printhead from damage.

[0016] The ring selectively contains or is composed of an elastic material, particularly rubber. This provides exceptionally good protection for the printhead, even when no marking profile is inserted and the printhead is closed.

[0017] The ring body selectively has a thickness ranging from 0.5 mm to 3.0 mm. This allows for good elastic support and effectively compensates for inaccuracies.

[0018] The support section of at least one of these sections, or at least a portion thereof, such as the carrier and / or ring, as previously described, may be rotatably supported on the shaft. This protects the printhead from damage.

[0019] For example, two support sections can be set up. A conveying section can be arranged between these two support sections. In this way, the marking profile can be laterally supported on both sides.

[0020] The base of the conveying section can be configured to consist of a sleeve that is rotatably and fixedly engaged with the shaft, thereby providing replaceable devices, such as multiple different conveying sections for marking profiles of different shapes. Alternatively, the base can be formed, for example, from a portion of the shaft and / or integrally formed with the shaft, achieving a particularly robust implementation.

[0021] Selectively, the shaft has at least segmental shape-fitting profiles, especially D-shaped profiles. This allows for easy retention of rotational fixation.

[0022] For example, at least one support section and / or conveying section is sleeved on the shaft and selectively secured axially to the shaft on both sides by a limiting member detachably fixed to the shaft. This allows for the formation of an easily replaceable unit.

[0023] The shaft can be configured to have an engagement portion for drive by a printer motor. This allows for easy removal and reinstallation of the shaft, and also ensures reliable drive. For example, the engagement portion may have a shape-fitting profile, such as a hexagonal profile.

[0024] According to one aspect, a printing cylinder for a printer used for printing marking profiles is provided, particularly a printing cylinder according to any one of the foregoing design schemes, comprising: a shaft, two support sections supported on the shaft, a transport section disposed between the two support sections and rotatably fixed to the shaft for propelling the marking profile by rotation of the shaft, wherein the transport section is composed of a substrate on which a coating (e.g., granular) is applied; and two retaining members detachably fixed to the shaft for axially fixing the support sections and the transport section to the shaft.

[0025] According to one aspect, a printer for printing marking profiles is provided, comprising a print roller according to any one of the designs described herein, and a print head arranged adjacent to or disposed adjacent to the print roller. The print roller is specifically arranged to press the marking profile against the print head.

[0026] According to one aspect, an arrangement structure is provided, comprising a printer according to any one of the design schemes described herein and a marking profile, wherein the receiving portion of the printer's print roller selectively has a shape that matches the bottom side of the marking profile.

[0027] In this device, the marking profile can be configured to have a printing surface on the upper side away from the bottom side, which can be printed by the print head.

[0028] Optionally, the marking profile has at least one snap-fit ​​element on its bottom side. The marking profile can, for example, be divided into multiple marking components. In this way, the marking components can be easily snapped onto, for example, an electrical terminal for identification.

[0029] According to one aspect, a method for manufacturing a printing roller according to any one of the design schemes described herein is provided, comprising the steps of: manufacturing or providing a substrate for a transport section, and applying a coating (especially a friction-enhancing coating) to the substrate to manufacture the transport section.

[0041] Figure 14 A view of an electrical terminal is shown, which can be accessed by... Figure 12 or Figure 13 The marking component is made of the marked profile shown. Detailed Implementation

[0042] Figure 1 A printer 2 for printing a marking profile 3 is shown, the printer and the marking profile 3 inserted into the printer 2 forming an integral arrangement. The marking profile 3 shown here is an end view and extends longitudinally. For example, the marking profile 3 can be unrolled from a roll. The length of the marking profile 3 can exceed 10 cm, and in particular, can exceed 1 m. The marking profile is made of a (especially thermoplastic) plastic, such as polyamide or polycarbonate. Exemplary molding forms of the marking profile will be combined later. Figure 12 and Figure 13 Further explanation.

[0043] Printer 2 also includes a print roller 1 driven by motor 21 of printer 2. Print roller 1 is supported in a manner rotatable about a rotation axis D relative to housing 22 of printer 2. Print roller 1 includes a shaft 10. In this embodiment, one end of shaft 10 of print roller 1 is supported in a rotary bearing 24. The rotary bearing 24 is mounted on housing 22. The rotary bearing 24 may be, for example, a sliding bearing, or a ball bearing, roller bearing, or a similar structure. Print roller 1 is rotatably arranged within housing 22 relative to housing 22. The other end of shaft 10 engages in a form-fit manner with the motor output shaft of a drive unit driven by motor 21, which together with motor 21 constitutes a motor-drive unit.

[0044] The printing roller 1 also includes at least one support section 11A, 11B supported on the shaft, and in the example shown, two such support sections 11A, 11B are included, as well as a conveying section 12 adjacent to the at least one support section 11A, 11B (located between the two support sections 11A, 11B) and rotatably fixedly connected to the shaft 10, for advancing the marking profile 3 by rotating the shaft 10 about the rotation axis D driven by the motor 21.

[0045] Based on the axis of rotation D defined by shaft 10, the conveying section 12 is radially recessed relative to the support sections 11A and 11B, thereby forming a receiving portion A for marking the profile. The support sections 11A and 11B (in the direction perpendicular to the axis of rotation D) have a larger diameter than the conveying section 12. The support sections 11A and 11B have a cylindrical shape. As will be further explained later, the conveying section 12 is constructed from a substrate 120 on which a friction-enhancing coating is applied. In the illustrated embodiment, the conveying section 12 has a cylindrical shape.

[0046] A printhead 20 of a printer 2 is arranged adjacent to the print roller 1. In the illustrated embodiment, the printer 2 is configured as a thermal transfer printer. Thermal transfer printers are particularly suitable for printing marking profiles 3, such as for label making. A transfer film 23 (e.g., in the form of a carrier film with an ink layer) is conveyed through the marking profile 3 to a location below the printhead 20 (here, for example, a thermal printhead) fixed within the housing 22. During this process, (tiny) resistive elements within the printhead 20 are heated by pulses of current, thereby causing ink dots to detach from the transfer film 23 and (permanently) transfer to the marking profile (e.g., the label portion of the marking profile 3) under the combined action of the resulting heat and the pressure exerted by the printhead 20 on the transfer film 23. This generates a printed image. The conveying of the marking profile 3 is accomplished by the print roller 1.

[0047] Printer 2 may optionally include a cutting device for cutting the printed marking profile 3 to form individual marking components, such as labels.

[0048] Figures 2 to 4 Two printing rollers 1 and 1' with different conveying sections 12 and 12' are shown. Figure 3 and Figure 4 The printing roller 1 shown is Figure 1 The printing roller 1 in the middle. Except for the differences in conveyor sections 12 and 12', Figure 2 and Figure 3-4 The printing rollers 1 and 1' shown may be identical. Alternatively, a build kit may be provided having a unique shaft 10 on which different transport sections 12 and 12' can be fitted to form different printing rollers 1 and 1'. This build kit or assembly may include, for example, a unique shaft 10, two support sections 11A and 11B (and optionally two retaining members 13 described later) and two or more different, replaceable transport sections 12 and 12'.

[0049] Each of the corresponding printing rollers 1 and 1', in addition to the shaft 10, also includes support sections 11A and 11B and two limiting members 13. Since these components are identical in both types of printing rollers 1 and 1', their functions and structures are determined accordingly. Figure 3-4 The printing roller 1 shown is used for illustration, but the same description also applies to printing roller 1. Figure 2 The printing roller 1' shown.

[0050] Shaft 10 has a longitudinally extending shaft with a form-fit profile. This form-fit profile allows correspondingly shaped components to be fitted onto it in a manner that prevents rotation relative to shaft 10 about the axis of rotation D. Here, shaft 10 has a flat portion 101 on one side along its longitudinal extension. The rest of the shaft is cylindrical, while the flat portion 101 has a plane. Its cross-section forms a D-shape, therefore the form-fit profile here is a D-shaped profile. Of course, other form-fit profiles can also be used, such as those with a polygonal cross-section.

[0051] Shaft 10 has a pin 102 at one end, which can be inserted into a rotary bearing 24 for rotatable support therein. Shaft 10 has an engagement portion 100 at the opposite end, which has, for example, a hexagonal profile or other shaped mating profile. This engagement portion can be fitted onto a corresponding shaft driven by motor 21. It should be noted that the end of shaft 10 on the motor side can alternatively be designed as a pin or similar structure (and / or the end on the bearing side can be formed as an engagement portion). On the motor side, the shaft (in the coupling section, for example, on the engagement portion 100) can be coupled to motor 21, so that motor 21 can transmit torque to shaft 10. On the bearing side, shaft 10 is rotatably supported (in the coupling section, for example, by a pin).

[0052] The conveying section 12, support sections 11A and 11B, and limiting member 13 are all sleeve-shaped and can be fitted onto the shaft 10, and are fitted onto the shaft in the assembled state. For example, they can be... Figure 7 , Figure 9 and Figure 10B As can be seen, the conveying section 12 has an inner contour that matches the shape-fitting contour of the shaft 10. Here, the inner through-hole of the conveying section 12 is provided with an anti-rotation structure 122, which in this example is formed by a flat surface within the inner contour, the rest of which is circular. Thus, the conveying section 12 has an internal D-shaped contour. The conveying section 12 (based on the rotation axis D) is axially fitted onto the shaft 10 and can slide along the shaft 10, while preventing such rotation through shape-fitting engagement of the shape-fitting contours for relative rotation between the conveying section 12 and the shaft 10. Therefore, rotation of the shaft 10 causes rotation of the conveying section 12.

[0053] For example, especially can be by Figure 5 and Figure 8 As can be seen, support sections 11A and 11B have circular inner contours. Therefore, support sections 11A and 11B are rotatably mounted on shaft 10 relative to shaft 10 about the axis of rotation D. Support sections 11A and 11B form a sliding bearing with shaft 10. Support sections 11A and 11B are identical in construction in this example.

[0054] When the support sections 11A and 11B contact the print head 20, they can support the print head, while the shaft 10 rotates within the support sections 11A and 11B, thereby protecting the print head. For example, it can be seen from... Figure 8 As seen in the diagram, support sections 11A and 11B each have a carrier 110 with an internal opening through which the shaft 10 passes, and a ring 111 surrounding the carrier 110. In this example, the carrier is made of a metallic material, such as aluminum or steel. The ring 111 is made of rubber. This compensates for unevenness and further enhances protection for the printhead 20. The ring 111 has a thickness ranging from 0.5 mm to 3.0 mm in the radial direction based on the axis of rotation D.

[0055] The print head 20 is movable relative to the shaft 10 between an open position and a closed position. In the open position, the marking profile 3 can be inserted, and the transfer film 23 can be replaced, for example. Additionally, the print roller 1 can be replaced. Even when the print head 20 is in the closed position without the marking profile 3 inserted (or when the inserted marking profile does not extend beyond the support sections 11A, 11B), the support sections 11A, 11B with the ring 111 still protect the print head 20.

[0056] The limiting member 13 can also be fitted onto the shaft 10 and each has a fixing element 130 for securing the respective limiting member 13 to the shaft 10. In the example shown, the fixing elements 130 are formed in the form of screws. Therefore, the limiting member 13 can be simply fixed to the shaft 10 by screws. The limiting member 13 thus achieves axial fixation on the shaft 10.

[0057] In the assembled state, especially as Figure 4 As shown, the conveying section 12 is arranged between two support sections 11A and 11B, and the conveying section 12 and the support sections 11A and 11B are arranged together between two limiting members 13. Thus, the conveying section 12 and the support sections 11A and 11B are fixed axially on the shaft 10, wherein the support sections 11A and 11B are rotatable.

[0058] The diameters of the support sections 11A and 11B are larger than the diameter of the conveying section 12. Therefore, a receiving portion A for the marking profile 3 is formed. Figure 3 –4 (see also) Figure 5 and Figure 6 In the example, the receiving part A is cylindrical. The outer peripheral surface M of the conveying section 12 (see example) Figure 10A It is cylindrical. The outer circumferential surface M extends substantially from one support section 11A to another support section 11B.

[0059] The conveying section 12 has stops 123 on both sides of its outer peripheral surface M (see example). Figure 7 , Figure 10A and Figure 10B In the example shown, the stops 123 are constructed in the form of flanges. The stops 123 abut against the support sections 11A and 11B without clamping. The stops 123 and the outer peripheral surface M are formed by the base 120 of the conveying section 12.

[0060] The substrate 120 has the aforementioned friction-increasing coating 121 on its outer peripheral surface M. This coating 121 is made of a material with a Mohs hardness of 7 or higher, preferably 8 or higher (selectively 9 or higher), exemplarily including corundum, and alternatively or supplementarily including carbides, especially tungsten carbide, and / or diamond. The coating 121 comprises particles of these materials. The particle size is from 0.1 mm to 0.25 mm, 0.25 mm in this example. These particles are applied to the substrate 120 by electroplating, or alternatively by bonding (or otherwise fixing or depositing thereon, e.g., by CVD). The coating 121 of the transport section 12 is... Figure 3 and Figure 4 In the middle, it is represented by dots, while Figure 5 -10B is for simplification only and is not shown. The coating 121' of the conveyor section 12' is in Figure 2The shaded area indicates the same thing. Figure 11A –11B is not shown for simplicity.

[0061] The coating 121 enables exceptionally good driving of the plastic marking profile 3, ensuring minimal slippage of the marking profile 3 during transport (printing), and even if slippage occurs, it remains extremely constant and has a long service life. This results in excellent printing quality.

[0062] The aforementioned replaceability of transport sections 12 and 12' also enables the use of the print roller 1 to handle different profile geometries (e.g., by designing transport sections 12 and 12' as replaceable sleeves). For other marking profiles 3, the user can also easily replace transport sections 12 and 12'. Furthermore, no mandatory new adjustments to the print roller 1 are required after replacing the replaceable parts. One of the limiting members 13 (here, the motor-side limiting member 13) can be retained on the print roller 1. Additionally, the print roller 1 can be laterally adjusted when needed for optimal positioning in the material transport path of the printer 2.

[0063] Figure 5 –9 shows the passage Figure 3 –4 shows the process of the printing roller 1 conveying the marking profile 3. The marking profile 3 is also shown in… Figure 12 The marking profile 3 has a printing surface 30 and a base. The printing surface 30 and the base are connected to each other by tabs (asymmetrically arranged in this example, i.e., arranged on one side of the base). The printing surface 30 (convex in this case) is formed on the upper side O of the marking profile 3, and the base is formed on the lower side U. The base is placed in the receiving portion A of the print roller 1, so that the lower side U contacts the coating 121. Thus, the marking profile 3 is driven at its lower side U, while its upper side O faces the print head 20. The material segment forming the printing surface 30 is placed on two support segments 11A, 11B by its lateral end segments, see, for example Figure 1 , Figure 5 and Figure 6 Therefore, the printing surface 30 receives additional support, while the feet are laterally attached to the support sections 11A and 11B, thereby preventing lateral sliding (parallel to the axis of rotation D).

[0064] At the base, the marking profile 3 has a locking element 31. The printed section of the marking profile 3 can be used to mark the equipment, for example, for marking such as... Figure 14The manufactured terminal 4. Here, the terminal 4 is in the form of a row terminal, for example, having multiple electrical connection portions 40 for electrical conductors. A receiving portion 41 for a section of the marking profile 3 is formed on the terminal 4. An engaging element 410 is formed on the receiving portion 41, which engages with the engaging element 31 on the marking profile 3. Thus, the printed section of the marking profile 3 can be easily inserted into one or more such terminals (or other devices).

[0065] Figure 13 It shows a shape different from Figure 12 The marking profile 3'. According to Figure 13 The marking profile 3' has a planar section with an upper side O' and a lower side U', and a printing surface 30' (planar in this example) is formed on the upper side O'. The lower side U' has an engaging element 31, for example for engaging with a receiving portion 41 of a terminal 4 or other device.

[0066] To transport the marking profile 3', you can use Figure 2 The print roller 1' is shown. For example, for this purpose, print roller 1 can be removed from printer 2 first (if print roller 1 is arranged in printer 2), and then inserted. Figure 2 The printing roller 1' is shown. During this process, the transport sections 12 and 12' can also be easily replaced.

[0067] Transport section 12' in Figure 2 , 11A As shown in 11B. The outer peripheral surface of the substrate 120' of the transport section 12' has a shape that matches the lower side U' of the marking profile 3'. In the example shown, the outer peripheral surface has two surrounding grooves and forms a cylindrical region between the two grooves in the axial direction. The coating 121' is formed both on the grooves and on the cylindrical region, wherein the coating 121' may also be formed only on the grooves or only on the cylindrical region. An annular receiving portion A' is formed for transporting the marking profile 3'. The marking profile 3' placed in the receiving portion A' abuts the print head 20 with its printing surface 30'. As previously mentioned, the substrate 120' also has an anti-rotation structure 122 at the internal opening for the shaft 10, see [link to previous section]. Figure 11B .

[0068] The method of manufacturing any of the above-mentioned printing rollers 1, 1' includes: manufacturing or providing a substrate 120, 120' for conveying sections 12, 12', and applying a coating on the substrate 120, 120' to manufacture the conveying sections 12, 12'.

[0069] The basic concept of the present invention is not limited to the above embodiments, and in principle it can also be implemented in completely different ways.
