Detailed Description

Fig. 1 illustrates an exemplary abrasive article web 100 having two exemplary abrasive article units 110, 120. In the illustration, the abrasive web 100 is provided with two abrasive unit cells 110, 120, but the abrasive web 100 may have any number of abrasive unit cells 110, 120. Here, the grinding tool units 110, 120 each preferably have a plurality of grinding tools 132 for machining the surface.

Preferably, these abrasive tool units 110, 120 are configured as endless bands, in particular as parallel endless bands. Preferably, the abrasive tool units 110, 120 are cut and/or stamped from the abrasive web 100 by a laser cutting process. By means of such cutting and/or punching, the endless strips of the abrasive tool units 110, 120, in particular parallel to each other, are preferably formed. Preferably, the abrasive tool units 110, 120 configured as endless bands are rolled up into a roll, but can alternatively be stacked by folding.

According to the invention, the grinding tools 132 of the plurality of grinding tools 132 are designed for use with a grinding robot that performs robotic grinding. In this case, the grinding tool 132 is arranged as a grinding tool unit 110, 120, so that the grinding robot can automatically, preferably fully automatically, remove the respectively required grinding tool 132 as required, wherein the respective error rate is relatively low. In addition, the grinding robot preferably also automatically removes so-called broken pieces, i.e. worn grinding stones.

In one embodiment, the grinding tools 132 of the plurality of grinding tools 132 are each configured in the form of a round or circular grinding disk. Preferably, the grinding disks 132 each have a hole pattern 135 having a plurality of recesses 133. Preferably, the recesses 133 are configured as punched holes. The hole pattern 135 can be designed in any way and is not limited to the arrangement of the recesses 133 shown in fig. 1. Here, the grinding tool units 110, 120 may also comprise grinding tools 132 having different grain sizes and/or hole patterns, i.e., for example, one grinding sheet having a first grain size and/or a first hole pattern and a subsequent or adjacent grinding sheet having a second grain size and/or a second hole pattern.

It should be noted, however, that the configuration of the grinding tool 132 as a round or circular grinding disk is merely an exemplary feature and is not to be construed as limiting the invention. The abrasive article 132 may also have any other shape, such as an oval or in a polygonal type configuration.

Preferably, the grinding tools 132 of the plurality of grinding tools 132 are arranged next to one another in a grinding tool row 199 and are connected to one another at least in sections. Preferably, the grinding tools 132 of the plurality of grinding tools 132 are arranged in a straight line one after the other, but may also be arranged offset from one another. Furthermore, in fig. 1, the two grinding tool units 110, 120 in two adjacent rows are arranged offset from one another in the illustration, in order to preferably obtain a low heel. However, the two grinding tool units 110, 120 in two adjacent rows can also be arranged parallel to one another, so that preferably one grinding tool 132 of a grinding tool unit 110 is arranged next to the other grinding tool 132 of a grinding tool unit 120, in particular in line.

Furthermore, at least one and preferably two conveying regions 134, 136 are preferably formed between two adjacent grinding tools 132 of the grinding tool row 199. The two conveying regions 134, 136 are preferably of polygonal design, wherein the corners can be rounded. Preferably, the two conveying regions 134, 136 are polygonal in configuration. In this case, at least one corner, preferably all corners, are rounded, so that undesired splitting or undesired tearing of the grinding tool 132 can be prevented when the grinding tools 132 of the grinding tool row 199 are torn off. In addition, the conveying areas 134, 136 serve as mechanical stabilization to protect the grinder units 110, 120 against horizontal bending.

It is noted that the configuration of the conveying zones 134, 136 as polygons has merely an exemplary character and should not be considered as limiting the invention. The delivery zones 134, 136 can also have any other form, such as circular or oval.

The two conveying areas 134, 136 preferably each have at least one conveying recess 137 for the precise conveying of the grinder units 110, 120 by the conveying unit of the respective grinding robot. In this case, the at least one transport recess 137 is adapted correspondingly to the transport unit.

The at least one conveying recess 137 is preferably designed as a bore, wherein the conveying unit is preferably designed as a pin which penetrates into the bore 137 for conveying. Thus, the grinder units 110, 120 may be provided independently of the corresponding hole pattern 135 of the grinder 132. Furthermore, the described configuration of the conveying regions 134, 136 makes it possible to achieve a rapid exchange process of the grinding disk 132, which is important in particular in robotic grinding in order to achieve a better beat frequency of the workpiece to be machined.

In one embodiment, a perforated connecting area 138 is formed between each of the grinding tools 132 of the plurality of grinding tools 132 and the associated transport areas 134, 136, in order to tear off the grinding tool 132 from the grinding tool units 110, 120. The perforated connecting region 138 is configured here such that an easy machine tear-off process can be carried out.

Preferably, one grinding tool 132 of the plurality of grinding tools 132 and the two conveying regions 134, 136 associated with the grinding tool 132 each form a repeating unit 130. Here, it is preferable that the grinding tool unit 110, 120 has a plurality of repeating units 130.

Fig. 2 illustrates the exemplary grinding tool unit 110 of fig. 1 and illustrates the arrangement of the plurality of grinding tools 132 as a grinding tool row 199. Here, the grinding tool row 199 is illustrated as having four repeating units 130. It is noted, however, that the configuration of the abrasive row 199 with four repeat units 130 is merely exemplary in nature and should not be considered as limiting the present invention. The abrasive article column 199 may have any number of repeating units 130.

Preferably, the grinding tool unit 110, 120 alternatively or optionally has at least one coding 230, which preferably provides information about the grinding tool unit 110, 120, the repeat unit 130 and/or the grinding tool 132 of the plurality of grinding tools 132. Preferably, the at least one coding 230 of the grinding tool unit 110, 120 is associated with the at least one repeating unit 130, the at least one grinding tool 132 and/or the at least one conveying region 134, 136. Preferably, each repeating unit 130, each abrasive article 132, and/or each conveying region 134, 136 has a coding 230. In fig. 2, in the illustration and by way of example, each grinding tool 132 has a coding 230. Here, the encoding portion 230 may have any shape and be disposed at any position of the grinder units 110, 120, the repeating unit 130, the grinder 132, and/or the conveying regions 134, 136. The coding 230 is preferably configured in the form of holes, dots and/or codes. The alternative and/or alternative coding can be glued, printed and/or stamped in this case.

The information transmitted by the encoding section 230 can be explained, for example: there are also how many sharpeners 132 on the sharpener units 110, 120 and so a forecast is given about the need to replace the sharpener units. Alternatively or additionally, the coding 230 may provide instructions regarding the type and/or grit size, etc. of the abrasive article 132. Furthermore, the information can alternatively or optionally be configured as a marking of the blank.

Fig. 2 furthermore shows two conveying regions 134, 136, wherein in fig. 2 the conveying region 134 is shown above in the illustration and the conveying region 136 is shown below in the illustration to connect two adjacent grinding tools 132 to one another at least in sections. In this case, the two conveying regions 134, 136 preferably each have a conveying recess 137 in the form of a bore. However, it is to be noted that the two conveying regions 134, 136 can also be configured differently from one another. Accordingly, the two conveying regions 134, 136 can have different shapes and/or a different number of conveying recesses 137, for example.

Figure 3 shows an enlarged area of the abrasive article web 100 of figure 1. Fig. 3 shows a conveying area 134, which has a conveying recess 137, which is arranged centrally in the conveying areas 134, 136 in the illustration. It is to be noted, however, that the illustrated arrangement of the at least one conveying recess 137 has merely exemplary features and is not to be considered as limiting the invention. The at least one conveying recess 137 can be arranged at any point of the conveying area 134 and/or the conveying area 136, for example, also not centrally or offset. Furthermore, the two conveying recesses 137 can also be configured differently from one another. For example, the transport gap 137 of the transport region 134 is centered and the transport gap 137 of the transport region 136 is not centered.

The number of the conveyance empty parts 137 may be different. For example, the conveying area 134 may have different numbers of conveying empty portions 137 from the conveying area 136. It is to be noted, however, that the number of correspondingly based conveying recesses 137 is preferably adapted to the conveying unit of the grinding robot, so that the grinder unit 110 of fig. 2 can be conveyed smoothly and precisely by means of the conveying unit.

Figure 4 shows the abrasive article web 100 of figure 1 having five abrasive article units 110 in the illustration. It is noted, however, that the configuration of the abrasive article web 100 having five abrasive article units 110 is merely an exemplary feature and should not be considered a limitation of the present invention. The abrasive web 100 may also have more or less than five abrasive unit cells 110.

Figure 4 schematically illustrates the grinder unit 110 separated by a cutting line and/or a punching line 420. In this case, the grinding wheel units 110 are arranged side by side in a suspended manner, but the grinding wheel units 110 can also be rolled up into a roll or folded into a stack after cutting and/or punching, as described above.

Figure 5 shows an enlarged region of the abrasive article web 100 of figure 1 including a transport region 134 configured in accordance with another embodiment. The conveying area 134 has a polygon, which has six corners in the illustration. At least one side of the polygon is curved. In the illustration, three of the six sides of the transport region 134 are configured as arcs. Furthermore, the corners of the conveying region 134, which is designed as a polygon, are preferably designed to be rounded, similarly to the conveying regions 134, 136 of fig. 1 to 4.
