Description

Printing roller for a printer with coated transport section

The invention relates to a printing roller for a printer for printing

marking profiles, a printer with such a printing roller, an arrangement with such a printer and a method for producing a printing roller,

Printing rollers are regularly used to print on print media. These rollers transport the print medium, e.g. paper, to a print head and optionally press it against the print head. With print media such as paper, feeding is relatively easy by rubberizing the print roller.

A printer with a printing roller for paper is described in US 2008 / 083 732 A1.

The pressure roller has fine particles to improve the transport of the paper,

If spatially extended and/or rigid printing media are to be transported compared to paper, the transport is usually more complex and the printing rollers are more susceptible to wear. WO 2018/1899066 A1 describes a printer for printing marker strips, whereby the printer has a motor-driven, rotatably mounted

Feed shaft and a print head. It is provided that the rotatably mounted feed shaft has at least one section provided with a sawtooth-like toothing, which, when the feed shaft rotates, directly on the

Marker strips are in contact so that the feed speed of the marker strip is synchronized with the peripheral speed of the feed shaft. However, this printer is complex to manufacture and requires a high contact pressure in order to achieve satisfactory transport. However, if the pressure is too high, permanent, visible impressions can remain in the marker strips, which reduces the quality of the end result. Setting a print with satisfactory

Results can sometimes be difficult for the user, but this can be done, for example,

Changing a ribbon may be necessary more often. This may result in unsatisfactory print results.

Further printers are described in US 4,780,729 A and WO 2019 / 238 492 A1,

The object of the present invention is to facilitate the transport of marking profiles to

To improve the printing of the marking profiles,

This object is achieved by an article having the features of claim 1,

Accordingly, a printing roller for a printer for printing marking profiles comprises a shaft, at least one support section mounted on the shaft and a transport section arranged adjacent to the at least one support section and connected to the shaft in a rotationally fixed manner for feeding the marking profiles by rotating the

Shaft, wherein the transport section is arranged opposite the at least one support section in

With respect to a rotation axis defined by the shaft, it is radially offset so that its

Holder for the marking profile is formed, whereby the transport section is formed by a

base body is formed on which a friction-increasing coating is applied,

This is based on the idea that especially the materials that are soft to the

Transport section enable a high durability, e.g. steel or aluminum, have a very low friction with the material, are typically made of soft marker strips, e.g. plastic such as PA, PC or PE. So even a

Gearing can only achieve a reliable feed with sufficient pressure,

A friction-increasing coating Kst compared to the material of the base body with the material of the marking profiles solves this problem in a simple way, so that a particularly reliable and easily adjustable transport is possible, well for the

Structure of the component and for the contact of the marking profiles different properties are provided. Such a printing roller also allows a particularly robust and durable design. The transport of marking profiles for printing the

Marking profiles improved,

The coating optionally comprises corundum, a carbide, in particular tungsten carbide, and/or diamond or consists of them. These materials are particularly durable and allow particularly good transport results.

Optionally, the (or a) material of the coating has a Mohs hardness of 8 or more, of 7 or more, in particular of 8 or more, in particular of 9 or more. Particularly good transport results can also be achieved in this way.

For example, the coating has a grain size of 0.1 mm to 0.5 or 0.7 mm, in particular from 0.1 mm to 0.25 mm. This prevents visible impressions particularly effectively and at the same time ensures particularly good friction with the

marking profiles,

Optionally, the coating is glued to the base body, e.g. with a resin or the like. Alternatively or additionally, the coating can be embedded in the material of the

Base body and anchored thereto, for example, a particularly effective

Anchoring is possible by applying the coating galvanically. Nickel is optionally deposited here, grains of the coating can be nickel-plated. The coating can also be applied by flame spraying.

Furthermore, the coating can be applied by chemical vapor deposition (SVD). Here, for example, carbon atoms of the gas are deposited as

Diamanic crystallites on the tool surface.

The at least one support section may comprise a carrier and a

Ring, The carrier is rotatably mounted on the shaft and/or the ring is rotatably mounted on the carrier. This way the print head can be protected from damage,

The ring optionally includes or consists of an elastic material, especially rubber. This enables particularly good protection of the print head, even if no

Marking profile is inserted into the printer and the print head is closed.

Optionally, the ring has a thickness of 0.5 mm to 3.0 mm. This allows a gule

Suspension and its guien compensation of inaccuracies,

The at least one support section, or at least a part thereof, such as the carrier and/or ring, can be rotatably mounted on the shaft as already mentioned.

Print head must be protected from damage.

For example, two support sections are provided. Between the two

The transport section can be arranged in support sections. This means that the marking profile can be supported laterally on both sides.

It can be provided that the base body of the transport section is formed by a sleeve that is in rotationally fixed engagement with the shaft, thereby creating an exchangeable arrangement, e.g. with several different

Transport sections for different shaped marking profiles. Alternatively, the

Base body e.g. formed by a part of the shaft and/or formed integrally with it, which allows a particularly robust design,

Optionally, the shaft has a form-fitting profile, particularly a D-profile, at least in sections. This makes it easy to provide a rotationally fixed mounting.

For example, the at least one support section and/or the transport section are attached to the shaft and, optionally, secured axially to the shaft on both sides by means of a stopper that can be releasably fixed to the shaft. This allows an easily replaceable

unity must be created.

It can be provided that the shaft has an inlet for driving by a motor of the

printer, so the shaft can be easily removed and reinserted.

In addition, a reliable drive can be guaranteed. For example, the

Intervention has a form-fitting profile, such as a Sschskaniprolil.

According to one aspect, there is provided a method of manufacturing a printing roller according to any embodiment described herein, comprising the following

Steps: Manufacture or provide the base body for the transport section and

Applying a coating (particularly one that increases friction) to the base body to produce the transport section,

The idea underlying the invention will be explained in more detail below using the embodiments shown in the figures. They show:

Fig. 14 is a view of an electrical terminal which is connected to a

Marking element can be marked using one of the marking profiles shown in Fig. 12 or 13.

Fig. 1 shows a printer 2 for printing marking profiles 3 in an arrangement with a marking profile 3 inserted into the printer 2. The marking profile 3 is here at the

Stimselte shown and is longitudinally extended. For example, the marking profile 3 is

Roll unrolled. The marking profile 3 can be longer than 10 om, in particular longer than 1m. The marking profile consists of a (particularly thermoplastic) plastic, e.g. polyamide or polycarbonate. Example shapes of marking profiles are explained below in connection with Fig. 12 and 13.

The printer 2 further comprises a printing roller 1, which is driven by a motor 21 of the

printer 2. The printing roller 1 is rotated about a rotation axis D relative to a

Housing 22 of the printer 2 is rotatably mounted, the printing roller 1 comprises a shaft 10.

In the present case, one end of the shaft 10 of the printing roller 1 is mounted in a pivot bearing 24.

The pivot bearing 24 is mounted here on the housing 22. The pivot bearing 24 is, for example, a plain bearing, although a ball bearing, roller bearing or the like is also conceivable. The pressure roller 1 is arranged in the housing 22 so as to be rotatable relative to the housing 22. The other end of the shaft 10 is in positive engagement with a

Motor output shaft of a transmission driven by the motor 21, which is connected to the

Motor 21 forms a motor-gearbox unit.

The printing roller 1 further comprises at least one support section 11A, 118 mounted on the shaft, in the example shown two such support sections 11A, 118, and a transport section 12 arranged adjacent to the at least one support section 11A, 118 (namely here between the two support sections 11A, 118) and connected in a rotationally fixed manner to the shaft 10 for feeding the marider profile 3 by a rotation of the shaft 10 about the axis of rotation D caused by the motor 21.

The transport section 12 is radially offset from the support sections 11A, 118 in relation to the axis of rotation D defined by the shaft 10, so that a receptacle À for the marking profile is formed. The support sections 11A, 118 have a larger

diameter (perpendicular to the axis of rotation D) than the transport section 12. The

Support sections 11A, 118 have a circular cylindrical outer shape. As explained in more detail below, the transport section 12 is formed by a base body 120 on which a friction-increasing coating is applied. In the example shown, the transport section 12 has a circular cylindrical shape.

A print head 20 of the printer 2 is arranged adjacent to the printing roller 1. In the example shown, the printer 2 is designed as a thermal transfer printer,

Thermal transfer printers are particularly well suited to create marking profiles 3, e.g.

Production of labels to be printed, A transfer film 23 (e.g. in the form of a carrier film with a color layer) is transported through the marking profile 3 under the fixed print head 20 (in the housing 22) (here, for example, in the form of a thermal line),

Here, (small) electrical resistances in the print head 20 are

Electricity pulses are used to heat the transfer foil 23, so that the heat generated in conjunction with the pressure of the print head 20 on the transfer foil 23 causes colour dots to be

Transfer foil 23 can be removed and applied (permanently) to the marker profile (e.g. on labels of marker profile 3). This creates a printed image. The transport of the

Marking profile 3 is carried out by means of the pressure roller 1.

The printer 2 optionally comprises a cutting device for cutting the printed marking profile 3 to form individual marking elements, e.g. labels,

Fig. 2-4 show two printing rollers 1, 1° with different transport sections 12, 12'. The printing roller | according to Fig. 3 and 4 is the printing roller 1 from

Fig. 1. The pressure rollers 1, 1° of Fig. 2 and 3-4 can, apart from the

Transport sections 12, 12° must be identical, optionally this is a

Kit with a single shaft 10 onto which the different transport sections 12, 12° can be fitted to form the different pressure rollers 1, 1°.

A kit or set comprises e.g. single wells 10, two support sections 11A, 11B (and optionally two stoppers 13 described below) and two or more different, interchangeable transport sections 12, 12°.

The respective pressure roller 1, 1° comprises, in addition to the shaft 10, the support sections 11A, 11B and two stoppers 13. Since these components are identical for both pressure rollers 1, 1°, their function and structure will now be explained using the pressure roller 1 of Fig. 3-4, which, however, applies analogously to the pressure roller 1" according to Fig. 2.

The shaft 10 has a longitudinally extending shaft, which is provided with a form-fitting profile. The form-fitting profile allows the attachment of correspondingly shaped components, secured against rotation relative to the shaft 10 about the axis of rotation D. The shaft 10 has a flattening 101 on one side along its longitudinal extension,

While the shaft is otherwise circularly cylindrical, the flattening 101 has a flat surface. In cross-section, the shape of a D results, so that the

The form-fitting profile is designed as a D-profile, but it should be noted that other form-fitting profiles are also conceivable, e.g. with a polygonal cross-section,

At one end, the shaft 10 has a pin 102 which can be inserted into the pivot bearing 24 in order to be rotatably supported therein. At the opposite end

At the end, the shaft 10 has an engagement 100, which is provided with a hexagonal contour or other form of hexagonal contour, for example. The engagement can be mounted on a corresponding shaft driven by the motor 21. It should be noted that the motor-side end of the shaft 10 can alternatively be designed as a SUf or the like (and/or the bearing-side end as an engagement). On the motor side, the shaft is (on a

Coupling section, such as 2.8, the engagement 100) can be coupled to the motor 21 in such a way that the motor 21 can transmit a torque to the shaft 10. On the bearing side, the shaft 10 is rotatably mounted with a coupling section, such as the St).

The transport section 12, the seat sections 11A, 11B and the sloppers 13 are each sleeve-shaped and can be plugged onto the shaft 10 and, in the assembled state,

As can be seen in particular from Fig. 7, 9 and 10B, the transport section 12 has an inner contour which is designed to match the form-fitting contour of the shaft 10. In the present case, the inner through-opening of the transport section 12 is provided with a rotation lock 122 which in the example shown is formed by a flat

Surface is formed in the otherwise circular inner contour. The

Transport section 12 thus has an inner D-profile. The transport section 12 is axially (with respect to the axis of rotation D} attached to the shaft 10 and can be moved along the shaft 10 and at the same time by the relative rotation between the

Transport section 12 and the shaft 10 are secured against such rotation by the form-mechanical engagement of the form-mechanical contours. A rotation of the shaft 10 thus causes a

rotation of the transport section 12.

The support sections 11A, 118 have a circular inner contour, as

This is particularly evident from Fig. 5 and 8. This allows the support sections 11A, 118 to be placed on the shaft 10 and rotated relative to the shaft 10 about the axis of rotation D. The support sections 11A, 115 form a glass bearing with the shaft 10. The

Support sections 11A, 118 are in this case designed identically to one another,

When the support sections 11A, 11B come into contact with the print head 20, they can rest on the print head while the shaft 10 is rotated in the support sections 11A, 11B.

This protects the print head. As illustrated in particular in Fig. 8, the support sections 114, 115 each have a carrier 110, which has the inner opening for the shaft 10, and a ring 111 surrounding the carrier 110. In the present example, the carrier is made of a metallic

Material, e.g. aluminum or steel. The ring 111 is made of

This allows unevenness to be compensated and the protection of the print copy 20 to be further improved. The King 111 has a radial direction in

With respect to the axis of rotation D, it has a thickness ranging from 0.5 mm to 3.0 mm.

The print head 20 is movable relative to the shaft 10 between an open position and a closed position. In the open position, a marking profile 3 can be inserted and, for example, the transfer film 23 can be changed. Furthermore, the printing roller 1 can be replaced. Even if the print head 20 is brought into the closed position, if no marking profile 3 is inserted (or if a marking profile is inserted which does not protrude beyond the support sections 11A, 11B), the support sections 11A, 11B having the rings 111 protect the print head 20.

The stoppers 13 can also be fitted onto the shaft 10 and each have a

Fastening element 130 for fixing the respective stopper 13 to the shaft 10. In the example shown, the fastening elements 130 are each designed in the form of a screw. This means that the stoppers 13 can be easily screwed onto the shaft 10. This

Stoppers 13 thus allow axial securing on the shaft 10.

In the assembled state, see in particular Fig. 4, the transport section 12 is arranged between the two support sections 11A, 11B and the transport section 12 and the

Support sections 11A, 11B are arranged together between the two Siopperm 13,

Thus, the transport section 12 and the support sections 11A, 11B are axially fixed to the shaft 10, wherein the support sections 11A, 11B are rotatable.

The support sections 11A, 118 have a larger diameter than the

Transport section 12. This creates a holder À for the marking profile 3,

Example of Fig, 3-4 (see also Fig, 5 and 6) the receptacle A is circular cylindrical, A

The surface area M (see z.8. Fig. 10A) of the transport section 12 is circular cylindrical.

Shell surface M extends essentially from one support section 11A to the other

support section 115,

The transport section 12 has a stop 123 on each side of the casing surface M, see e.g. Fig. 7, 10A and 10B. In the example shown, the stops 123 are each designed in the form of a flange. The stops 123 cause a clamping contact with the support sections 11A, 11B. The stops 123 and the casing surface M are formed by the base body 120 of the transport section 12.

The base body 120 has the aforementioned friction-increasing coating 121 on the surface M. The coating 121 has a material with a Mohs hardness of 7 or more, of 8 or more (optionally of 3 or more) and here comprises, for example, corundum, alternatively or additionally a carbide, in particular

Tungsten carbide, and/or diamond, The coating 121 comprises grains of this material,

The grains have a grain size of 0.1 mm to 0.25 mm, here 0.25 mm. The grains are galvanically applied to the base body 120, alternatively glued on (or attached to it in some other way or deposited on it, e.g. by means of CVD). The

Coating 121 of the transport section 12 is shown in Figs. 3 and 4 by a

Dots are illustrated and shown in Fig. 5-108 only for reasons of simplified

Illustration not shown. The coating 121° of the transport section 12’ is illustrated in Fig. 2 by hatching and also in Figs. 11A-11B8 only from

Not shown for reasons of simplified representation.

The coating 121 allows a particularly good drive of the plastic marking profile 3, ensures a particularly low and, if present at all, also particularly constant slip of the marking profile 3 during transport (printing) and has a long service life. As a result, very good 358 printing results are possible.

The previously described interchangeability of the transport section 12, 12° also enables the processing of different profile geometries with the printing roller 1 (by the transport section 12, 12' being designed, for example, in the form of an exchangeable sleeve). The transport section 12, 12' can also be easily exchanged by the user for alternative marking profiles 3. After exchanging exchangeable parts, no new adjustment is required on the printing roller 1. One of the stoppers 13 (here the motor-side stopper 13) can be left on the printing roller 1. In addition, the

Pressure roller 1 can be adjusted if necessary for optimal positioning on the material path of the

printer 2 can be adjusted.

Fig. 5-9 illustrate the transport of the marking profile 3 through the printing roller 1 according to Fig. 3-4. The marking profile 3 is also shown in Fig. 12. The marking profile 3 has a printing surface 30 and a foot. The printing surface 30 and the foot are connected to one another via a web (in this case asymmetrical, namely arranged on one side of the foot). The (convex in this example) printing surface 30 is formed on an upper side © of the marking profile 3, the foot on a lower side U. The foot is inserted into the receptacle À of the printing roller 1, so that the lower side U on the

Coating 121 rests, The marking profit 3 is thus driven on the underside U, while the upper side © faces the print head 20, The material section forming the printing surface 30 rests with rope end sections on the two

Support sections 11A, 118, see e.g. Fig. 1, 5 and 6. In this way, the printing surface 30 is additionally supported, while the foot rests laterally on the support sections T1A, 116 and is thus secured against lateral slipping (parallel to the axis of rotation D}.

At the base, the marking profile has 3 locking elements 31, a printed section of the

Marking profile 3 can be used to mark a device, e.g.

Identification of a terminal 4, as shown in Fig. 14. The terminal À, here in the form of a series terminal, has several electrical connections 40 for electrical conductors. On the terminal 4 there is a receptacle 41 for a section of the

Marking profile 3 is formed. On the holder 41, locking elements 410 are formed, with which the locking elements 31 of the marking profile 3 can lock. Thus, a printed section of the marking profile 3 can be easily inserted into one or more such

terminals (or other devices}.

Fig. 13 shows a differently shaped marking profile 3 compared to Fig. 12. The marking profile 3 according to Fig. 13 has a surface section which has a top side ©' and its

bottom U’ and on the top 0° a (in this example flat)

Printing surface 30°, On the underside U locking elements 31 are designed for locking e.g. with the holder 41 of the terminal 4 or another device,

To transport the marking profile 3°, the printing roller 1° can be used as shown in Fig. 2. For this purpose, for example, the printing roller 1 can be removed from the printer 2 if it is located therein and the printing roller 1° as shown in Fig. 2 is inserted. The transport section 12, 12° can also be easily replaced.

The transport section 12° is illustrated in Figs. 2, 11A and 115. An outer

Circumferential surface of the base body 120° of the transport section 12° has a

Bottom U of the marking profile 3° has a suitable shape. In the example shown, the outer circumferential surface has two circumferential grooves and a circular cylindrical area in between in the axial direction. The coating 121° is formed both on the grooves and on the circular cylindrical area, although it would also be conceivable to form the coating 120 only on the grooves or only on the circular cylindrical area. The ring-shaped

Holder À is designed to transport the marking profile 3°. The inserted

Marking profile 3° borders with its printing surface 30’ on the print head 20. As already described, the base body 120° also has a rotation lock 122 on the inner opening for the shaft 10, see Fig. 11B,

embodiment, but can also be implemented in a completely different way,
