Definitions
- the invention relates to a bar arrangement with a bar for holding gauge parts (modules) of tufting and knitting machines consisting of module bodies and tools held therein, with a receiving space extending over the entire length of the bar.
- U.S. Patent 44 83 261 shows e.g. such a bar, in which the modules are immersed in a receiving space extending over the entire length of the bar.
- Such a bar usually has a length of several meters and requires the attachment and, if necessary, replacement of a large number of the modules described above. Consequently, it takes a lot of time to equip or convert such a bar.
- the object of the present invention is to provide a bar arrangement with which the equipping or retrofitting is simplified, accelerated without reducing the precision of the assembly and, moreover, simple replacement of individual modules is made possible.
- each clamping screw has one has in the guide groove engaging guide pin and that the head of each clamping screw is sunk in the bore of a module body or a pressure piece .
- the modules can be combined outside of the bar with a fitting piece and, if necessary, with an additional pressure piece to form a composite. These composites can then be quickly and easily threaded into the intermediate space of the bar arrangement and fixed there by tightening the 5 tensioning bars. By loosening the clamping bar and loosening the clamping screws, individual modules can be exchanged, in particular to replace broken tools.
- the bar arrangement according to the invention can be designed such that each module body is clamped between a fitting piece and a pressure piece by means of at least one clamping screw.
- the head of the clamping screws should not be countersunk in the module body, but in a pressure piece.
- the bar arrangement according to the invention can also be designed such that the module body protrudes beyond the fitting piece from the bar arrangement and that a stop shoulder of the module body against a dimensioned surface of the adapter. Through the interaction of the stop shoulder of the module body and the dimensional surface of the fitting, the entry depth of the module and thus that of the tools contained therein are precisely defined.
- the bar arrangement according to the invention can be designed in such a way that the width of the composite of module body, adapter piece and optionally pressure piece is up to 1/10 mm larger than the minimum distance between the stop surface and the inner surface of the tensioning strip. In this way, a secure clamping of the composites in the space between the bar arrangement is ensured.
- the bar arrangement according to the invention can also be designed such that pressure screws are screwed into the tensioning bar, which are each effective against a pressure piece of a composite or against a module body. In this way, the groups become each by pressing
- the bar arrangement according to the invention can also be designed such that the bar has an L-profile rotated by 180 ", a first leg of this profile forming the ceiling surface and being screwed to the tensioning strip, while the second leg is Stop surface forms.
- the bar arrangement according to the invention can also be designed in such a way that a module is assigned 30 modules.
- each module body has at least one opening for the passage of a clamping screw.
- the bar arrangement according to the invention can also be designed such that the opening in the module body is designed as an elongated hole that is open at one end. This training can be useful when replacing individual modules.
- FIG. 1 shows a section through a bar arrangement according to the invention with modules carrying tufting needles
- FIG. 2 shows a side view of a module according to FIG. 1
- FIG. 3 shows a further embodiment according to the invention with modules carrying grippers
- FIG. 4 shows a section through a bar arrangement according to FIG. 1, pressure screws being provided in the tensioning bar
- FIG. 5 shows a side view of a module according to FIG. 1 with an elongated hole open at one end.
- a first leg 2 of this profile has a ceiling surface 3.
- a second leg 4 has a flat stop surface 5 which extends normal to the ceiling surface 3.
- the stop surface 5 is provided with a continuous guide groove 6 over its length.
- a clamping bar 8 is screwed to the first leg 2 of the bar 1 by means of screws 7.
- the clamping bar 8 can extend over the entire length of the bar 1 or can be divided into several sections. It has a flat inner surface 9 which is directed parallel to the stop surface 5. Push-through openings 10 for clamping screws 11 are provided in the clamping strip 8.
- the ceiling surface 3 forms a receiving space 12 with the stop surface 5, which is additionally limited by the inner surface 9 of the tensioning strip 8.
- Each adapter 13 has two mutually parallel sides 16, 17 and an outer dimension surface 18.
- the side 16 of adapter 13 lies against the stop surface 5 of the bar 1.
- the adapter 13 also has a head surface 19 which 10 comes to rest on the ceiling surface 3.
- a threaded bore 20 is provided for a clamping screw 11.
- the needle module 14 has a module body 21 in which exactly 22 needles 22 are positioned.
- the module body 21 has an opening 23 through which a clamping screw 11 can be inserted.
- a stop shoulder 24 is provided on the module body 21 and comes into contact with the dimensioned surface 18 of the adapter 13.
- the pressure piece 15 has two parallel sides, one of which rests on the module body 21 and the other on the inner surface 9 of the clamping bar 8.
- a threaded hole 25 for a clamping screw 11 is provided in the fitting 13.
- Each clamping screw 11 has a guide pin 26 at its front end.
- At least one clamping screw 11 connects a fitting piece 13, a needle module 14 and a pressure piece 15 to form a composite whose width measured in the direction of the axis of the clamping screw 11 is slightly larger than the length measured in the same direction
- the clamping screw 11 has a countersunk head 27 which is arranged countersunk in the threaded bore 25 of the pressure piece 15.
- the composites are put together outside the ingot arrangement and then inserted into the receiving space 12 from one end of the ingot arrangement, the guide pins 26 of the composites being guided in the guide groove 6.
- the needle modules 14 abut one another directly and the heads 27 of the clamping screws 10 are located behind the push-through openings 10 of the clamping strip 8.
- FIG. 3 shows a bar 1 with a ceiling surface 3 and a stop surface 5.
- a bar 8 is connected to the bar 1 by means of screws 7.
- a receiving space 12 is thus formed.
- the gripper module 30 has two stop shoulders 32, 33, which come to rest on a dimension surface 34 of the adapter 13 and on the clamping bar 8.
- modules are introduced and replaced in the manner already described. 4 largely corresponds to that of FIG. 1.
- a ⁇ pressure screw 36 is provided in the threaded bar 35 in a threaded bore 35, at least for each assembly, so that the clamping can be set and released separately for each assembly.
- an elongated hole 39 0 which is open at one end is provided in the module body 38 of a module 37 for receiving a clamping screw 11, so that the removal or insertion of a module 37 is possible without the clamping screw 11 to have to pull out of the module 37.
- the module 37 has two stop shoulders 40 so that it can function in the same way in the two positions rotated by 180 ° with respect to one another. ⁇ In this way, rotary movements are spared and assembly is accelerated.
- the bar arrangement can be used with various types of modules. It is possible to use modules that carry tools arranged in several rows. Furthermore, it is possible to use several rows of modules lying next to one another, that is to say with tools (22) arranged in several rows, eg. B. tufting needles to work.
