Definitions
- the invention relates to a module and bar for tufting tools, in particular needle module and needle bar, in which the tufting tools are cast at one end into a plate-shaped base body of the module, the length of which corresponds to a multiple of the center distance of the cast-in tufting tools and the one level , on a flat contact surface of the bar and has at least one opening through which a fastening screw can reach and be screwed into the bar.
- the basic module body has an opening, e.g. in the form of a hole through which a screw is passed.
- a corresponding threaded hole is provided in the bar.
- a bar with a module is known, in which the module additionally has a stop bar and a vertically running guide bar which engages in a corresponding groove in the needle bar.
- the guide bar should align and center the module.
- the mounting hole extends through the guide bar.
- the stop bar does not always strike the bar exactly, so that the module can move slightly vertically with large forces.
- a bar with modules for tufting tools is already known, in which a longitudinal groove is incorporated into the bar and each module engages in this groove with a protruding shaped piece, so that the module is held against rotation is.
- the module is to be held in a vertical and horizontal direction by means of a dowel screw or a collar which surrounds the bore of the module and which engages in the bar.
- this module When installed, this module is relatively secure against rotation, but must be fixed with a special dowel screw for precise installation in the longitudinal direction of the bar. If no such fitting screw is used, the module can be displaced, albeit slightly, in the longitudinal direction of the bar due to the considerable thread forces on the tools. The shift is reflected in the uneven structure of the goods made with the tools.
- the invention has for its object to design the modules or the bar with simple means so that a module is securely fixed in all directions.
- the object is achieved in that the module is positively fixed to the bar in the vertical direction with a first tongue and groove connection and in the horizontal direction with a second tongue and groove connection and is non-positively connected with the fastening screw in the direction of the bar is held.
- the arrangement can be designed such that a continuous horizontal longitudinal groove is provided both in the bar and in the module in order to form the first tongue and groove connection and that a common key engages in both longitudinal grooves.
- the arrangement can, in a preferred manner according to the invention, also be designed in such a way that a continuous horizontal longitudinal groove is formed in the bar to form the first tongue and groove connection and a horizontal bar protruding normal to its flat surface is formed on the module and is formed in the Longitudinal groove of the bar engages positively.
- the arrangement can also be constructed according to the invention in such a way that a continuous horizontal longitudinal groove is introduced into the module to form the first tongue and groove connection and a horizontal bar protruding normal to its contact surface is formed on the bar, which is inserted into the longitudinal groove of the Module engages positively.
- the arrangement can also be designed such that the module has two longitudinal grooves separated from one another by a crosspiece, that the crosspiece positively engages in a correlating recess of a parallel key inserted in a longitudinal groove of the bar, the area between the recesses ⁇ che positively engage in the longitudinal grooves of the module.
- protruding fitting pieces can be provided according to the invention, each of which engages in a form-fitting manner in an elongated hole provided in the module.
- transverse grooves can also be provided and at least one vertical bar that is normal to the horizontal bar and is formed on the module, which is in such a groove of the bar intervenes positively.
- grooves extending transversely thereto can be provided and vertical bars which extend into the bar and which are normal to the horizontal bar can be formed on them Intervene in the form of the module.
- the arrangement can also be designed such that the module has an elongated hole running in the vertical direction, the width of which corresponds to the diameter of a dowel screw with which the module is fastened to the bar.
- the elongated hole can be open both in this embodiment and in the embodiment with a fitting as a second tongue and groove connection to the upper edge of the module.
- the grooves can be milled.
- the module can have a second flat surface on the side opposite the flat surface, on which corresponding strips are formed.
- the module can then also be used in an arrangement rotated by 180 °.
- molded strips are provided, these should preferably be worked out as a fit.
- the strips can be molded onto the module using the injection molding process.
- the invention has the advantage that the module is fixed so that it can be shifted and rotated in all directions when it is inserted.
- a normal screw connection can be used to hold onto the bar.
- FIG. 1 shows a first embodiment of the invention in perspective view
- FIG. 2 shows a module corresponding to the embodiment of FIG. 1 in a perspective top view of the contact surface
- FIG. 4 shows the key designed according to the embodiment of FIG. 3,
- FIG. 5 shows a module corresponding to the embodiment according to FIG. 3 in a perspective view
- 6 shows a further embodiment of the invention in perspective view
- Fig. 7 shows a module according to the embodiment of FIG. 6 in perspective view
- Fig. 10 is a module corresponding to the embodiment of FIG. 9 in perspective view
- FIG. 11 shows a cross section through a module corresponding to FIG. 10.
- the drawings show a module with a basic body 1. With its flat surface 2, the module rests on the contact surface 3 of a needle bar 4.
- the tufting needles 5 are cast with their pistons in the basic body 1.
- the base body 1 is provided with a bore 6, through which a screw 7 is passed and with which the module can be held on the needle bar 4.
- a T-shaped molding consisting of a horizontal web 8 and a vertical web 9, is formed on the base body 1.
- the horizontal web 8 is received by a longitudinal groove 10 in the needle bar 3.
- vertically directed grooves 12 are provided in a vertical extension between the longitudinal groove 10 and the lower edge 11 of the needle bar 4.
- the grooves in the needle bar are milled.
- the webs 8 and 9 are worked as a fit for the grooves.
- the module With the screw 7, the module is attached to the needle bar 3 and is thus also fixed in the remaining sixth direction. Even with high forces, the module cannot be displaced or rotated. When replacing modules, the position of the replaced module is taken up again without any adjustment measures by a new module.
- Figures 3-5 show a second variant of the invention.
- a special key 13 is inserted into the longitudinal groove 10 of the needle bar 4 and engages with its parts which protrude beyond the contact surface 3 into two horizontal grooves 14 of the module.
- Both grooves 14 extend from the edge of the Grundgro ⁇ ers 1 and leave a web 15 between them, which engages in a corresponding recess 16 of the key 13.
- the grooves 14 are already molded during the manufacture of the module by injection molding and do not have to be specially worked out.
- FIGS. 6-8 show a further variant of the invention.
- the needle bar 4 has a continuous longitudinal groove 10.
- a parallel key 17 is inserted into the longitudinal groove 10 and its part protruding beyond the contact surface 3 projects into a longitudinal groove 18 of the module.
- the module is thus fixed in both vertical directions.
- the fixation in the horizontal directions takes place by means of a fitting piece 19.
- the fitting piece 19 is inserted into a groove-like recess in the needle bar 4, which attaches directly to the upper edge of the needle bar 4.
- the opening in the module is not designed as a hole, but rather as a U-shaped opening 21 which is open at the top.
- the length of the adapter 19 in the axial direction of the needle bar 4 is dimensioned such that the module with its U-shaped opening 21 can be positively placed on the part of the adapter 19 projecting beyond the contact surface 3 of the needle bar 4.
- the needle bar 4 has a continuous longitudinal groove 10, in which a fitting spring 17 is inserted.
- the module is correlated with a longitudinal groove 18.
- the Fi The module is fixed in the longitudinal direction of the needle bar 4 by a fitting screw 22.
- the opening in the module is designed as an elongated hole 23, the width of the elongated hole 23 corresponding to the diameter of the fit of the fitting screw 22. The module is thus clearly fixed in all directions.
