Tool module for textile machines
The invention relates to a tool module ( 10 ) having a module body ( 11 ), which has a contact surface ( 21 ) and an orienting structure ( 22 ). A fastening opening ( 29 ) and additionally at least one, preferably a plurality of additional openings ( 33, 34 ) extend through the contact surface ( 21 ). The area of one additional opening ( 33 ) or ( 34 ) is larger than, preferably considerably larger than, for example at least twice or three times as large as the cross-sectional area of the fastening opening ( 29 ). Thus, a module body ( 11 ) is provided, by means of which an increased operating speed of the textile machine can be achieved.
1. A tool module ( 10 ), particularly for tufting applications, comprising:
a module body ( 11 ) that comprises an alignment structure ( 22 ) including an abutment surface ( 21 ) for positioning at a bar,
tools ( 12 - 18 ) held in the module body ( 11 ),
a fastening opening ( 29 ) that penetrates the abutment surface ( 21 ) and the module body ( 11 ),
at least one additional opening ( 33 , 34 ) that penetrates the abutment surface ( 21 ) and the module body ( 11 ) that is separate from the fastening opening ( 19 ),
wherein the at least one additional opening ( 33 , 34 ) of the module body ( 11 ) is arranged in a zone between the fastening opening ( 29 ) and a ridge ( 26 ) arranged adjacent to a narrow side ( 20 ) of the module body ( 11 ) and serves as an alignment structure ( 22 ), and
wherein the module body ( 11 ) is separated into a fastening section ( 31 ) and a tool holding section ( 32 ) by the at least one additional opening ( 33 , 34 ), wherein the fastening section ( 31 ) and the tool holding section ( 32 ) are connected with each other via at least two webs ( 33 , 38 , 39 ).
2. The tool module according to claim 1 , wherein the abutment surface ( 21 ) has a flat configuration.
3. The tool module according to claim 1 , wherein the alignment structure ( 22 ) comprises projections ( 23 , 24 ) extending away from the abutment surface ( 21 ).
4. The tool module according to claim 3 , wherein the projections ( 23 , 24 ) include two prismatic, cylinder-shaped or dome-shaped projections ( 23 , 24 ) that extend parallel to each other away from the abutment surface ( 21 ).
5. The tool module according to claim 1 , wherein the ridge is an interrupted or continuous ridge ( 26 ) and is part of the alignment structure ( 22 ) adjoining a narrow surface ( 20 ) of the module body ( 11 ) and extending beyond the abutment surface ( 21 ).
6. The tool module according to claim 4 , wherein the projections ( 23 , 24 ) are arranged on a reference line ( 28 ) that is oriented parallel to the ridge ( 26 ).
7. The tool module according to claim 6 , wherein the fastening opening ( 29 ) is arranged on the reference line ( 28 ).
8. The tool module according to claim 1 , wherein the fastening opening ( 29 ) is configured in an insert ( 30 ) provided with an inner thread.
9. The tool module according to claim 1 , wherein the at least one additional opening comprises two openings ( 33 , 34 ) that are separate from the fastening opening ( 29 ).
10. The tool module according to claim 9 , wherein the two openings ( 33 , 34 ) are configured mirror symmetrically to each other.
11. The tool module according to claim 6 , wherein the at least one additional opening comprises two openings ( 33 , 34 ) arranged on a second reference line that is parallel to the reference line ( 28 ) on which the projections ( 23 , 24 ) are arranged.
12. The tool module according to claim 1 , wherein the at least two webs ( 37 , 38 , 39 ) comprise equal cross-sections.
13. The tool module according to claim 1 , wherein the module body ( 11 ) is a molded part.
