"Dispositif pour commander les releveurs de platines des
machines à tisser Dobby"
L'invention concerne un dispositif pour commander les releveurs de platines des machines à tisser
Dobby qui @ubordonne suivant un programme les releveurs de platines aux lames."Device for controlling the plate lifters of
Dobby weaving machines "
The invention relates to a device for controlling the plate lifters of weaving machines.
Dobby who @ubordinates according to a program the plate lifters with blades.
Les machines Dobby connues commandent les releveurs de platines sur les lames d'une machine Dobby au moyen d'un dispositif mécanique à impulsions compliqué. Known Dobby machines control the plate lifters on the blades of a Dobby machine by means of a complicated mechanical impulse device.
L'invention a pour but de réaliser un di- positif simple pour machine Dobby qui permette de subor- donner lez releveurs de platines aux lames pour leur commande. Ce problème est résolu suivant l'invention, du fait que chaque releveur de platine -est pourvu d'une surface d'application qui sert à établir le contact avec le support, ce dernier étant associé à l'électro-aimant et étant command par lui suivant un programme. The object of the invention is to produce a simple device for a Dobby machine which makes it possible to subordinate the plate lifters to the blades for their control. This problem is solved according to the invention, because each platen lifter -is provided with an application surface which serves to establish contact with the support, the latter being associated with the electromagnet and being controlled by him following a program.
D'autres avantages et caractéristiques de l'invention ressortiront de la description d'un exemple de réalisation représenté dans les dessins
Dans ces dessins, les figures 1 et 2 montrent la disposition qui permet de commander une lame suivant la demande N P 23 00 032.Other advantages and characteristics of the invention will emerge from the description of an embodiment shown in the drawings
In these drawings, FIGS. 1 and 2 show the arrangement which makes it possible to control a blade according to request NP 23 00 032.

Après libération du releveur de platine 1, 1' au moyen d'un support 5, 5', ce releveur de platine 1, 1' est de nouveau connecté à la lame 2, 2', et l'élévation de la lame, qui n'est pas représentée, est provoquée au moyen d'un autre mécanisme par sa rotation dans une autre position terminale. If, according to the program, there has to be a lifting of the not shown, the support 7, 7 ′ (FIG. 1) is rotated and is held by means of an electromagnet 8, 8 '.

After release of the plate lifter 1, 1 'by means of a support 5, 5', this plate lifter 1, 1 'is again connected to the blade 2, 2', and the elevation of the blade, which is not shown, is caused by another mechanism by its rotation in another terminal position.
Si, suivant le programme, la lame doit descendre, le support 7, 7' reste appuyé par la traction du ressort 10, 10', dans sa position de base et se dresse sur la butée 11, 11' (figure 1), où il retourne, en commun avec le guide de manoeuvre 12, 12' dans sa position de base, et le releveur de platine s'applique, après sa libération sur le guide 5, 5', par sa surface d'appui 6, 6', sur le support 7, 7'. La lame 2, 2'.tourne sans le releveur de platine 1, 12 1' engagé, c'est-à-dire que l'élément de foule, qui n'est pas représenté, descend. If, according to the program, the blade must descend, the support 7, 7 'remains supported by the traction of the spring 10, 10', in its basic position and stands on the stop 11, 11 '(figure 1), where it returns, in common with the operating guide 12, 12 'to its basic position, and the plate lifter applies, after its release on the guide 5, 5', by its bearing surface 6, 6 ' , on the support 7, 7 '. The blade 2, 2 ′. Rotates without the plate lifter 1, 12 1 ′ engaged, that is to say that the crowd element, which is not shown, descends.
La commande électro-magnétique du support 7, 7' se déroule suivant un programme qui est mis en mémoire dans une mémoire électronique, qui n'est pas représentée, d'où elle est reprise séparément pendant le fonctionnement. The electro-magnetic control of the support 7, 7 'takes place according to a program which is stored in an electronic memory, which is not shown, from which it is taken up separately during operation.
Ce mode de réalisation d'une machine Dobby commandée électroniquement permet le synchronisme de llac- tivité de la machine, c'est-à-dire que, pendant le retour, les fils de trame qui viennent d'être tissés peuvent outre retirés sans difficulté de la foule qui continue à avancer. This embodiment of an electronically controlled Dobby machine allows the synchronization of the activity of the machine, that is to say that, during the return, the weft threads which have just been woven can furthermore be removed without difficulty. of the crowd that continues to advance.
