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. 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.

  • 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.

Abstract

L'invention concerne un système de platine comprenant une platine (1) servant à maintenir des modules dont chacun comporte un nombre de corps (21; 31; 38) portant des outils de tufting, de tricotage ou de tricotage Rachel, et présentant chacun deux faces parallèles. Il est prévu dans cette platine (1) qu'une surface de couverture (3) plane et qu'une surface d'arrêt (5) plane perpendiculaire à la précédente, délimitent un espace s'étendant sur toute la longueur de la platine (1). Une barre de serrage (8) vissée sur la platine (1) comporte une surface intérieure (8) parallèle à la surface d'arrêt (5). La barre de serrage (8) comporte des ouvertures de passage pour des vis de serrage. Il est prévu dans la surface d'arrêt (5) de la platine (1) une rainure de guidage (6) s'étendant sur toute sa longueur. Chaque corps de module (21; 31; 38) est serré contre un adaptateur (13) à l'aide d'une vis de serrage (11), au moins sur le côté qui fait face à la surface d'arrêt (5). La largeur de l'ensemble formé par les corps de module (21; 31; 38), l'adaptateur (13) et éventuellement une pièce de poussée (15) supplémentaire, est adaptée à l'écart existant entre la surface d'arrêt (5) et la surface intérieure (9) de la barre de serrage (8). Chaque vis de serrage (11) comporte un téton (26) qui s'engage de manière guidée dans la rainure de guidage (6). La tête de chaque vis de serrage (11) est encastrée dans l'alésage d'un corps de module (21; 31; 38) ou d'une pièce de poussée (15). Ce système de platine simplifie l'équipement et l'adaptation d'unités de ce type et facilite le remplacement d'outils défectueux.
