Abstract

The installation is for operating sinker levers in a high-speed shank machine and aligns the sinker levers with the shaft blades. The operating arm has a support surface for contact with the support, which is controlled by an electromagnet. The sinker lever is shifted by means of a double-armed lever with a spring and a roller and by using an operating arm. The use of a pair of electromagnets enables electronic programme design and control. As a result, programming is simplified and costs reduced.

Description

"Dispositif pour commander les releveurs de platines d'une
machine à tisser Dobby tournant à grande vitesse."
L'invention concerne un dispositif pour actionner les releveurs de platines d'une machine à tisser
Dobby marchant à grande vitesse qui subordonne les releveurs de platine suivant un programme aux lames.
"Device for controlling the plate lifters of a
Dobby weaving machine spinning at high speed. "
The invention relates to a device for actuating the plate lifters of a weaving machine
Dobby walking at high speed who subordinates the platen levers according to a blade program.

Les machines Dobby à grande vitesse connues subordonnent les releveurs de platine aux lames au moyen d'un levier actionné par un carton perforé La confection des cartons perforés est toutefois compliqúde et coûteuse,
L'objet de l'invention est de réaliser un dispositif pour machines Dobby qui permette de subordonner et commander électroniquement le releveur de platine par rapport aux lames et supprime ainsi la confection difficile des cartons perforés.
Known high-speed Dobby machines subordinate the platen levers to the blades by means of a lever actuated by a perforated cardboard The production of perforated cardboards is however complicated and expensive,
The object of the invention is to provide a device for Dobby machines which makes it possible to electronically subordinate and control the platen lifter with respect to the blades and thus eliminates the difficult preparation of perforated cartons.

A cet effet, l'invention propose que le guide linéaire soit pourvu d'une surface d'appui qui sert à dtablir le contact avec le support associé à ltélectro- aimant, cet électro-aimant commandant le support suivant un programme. To this end, the invention proposes that the linear guide be provided with a bearing surface which serves to establish contact with the support associated with the electromagnet, this electromagnet controlling the support according to a program.

D'autres avantages et caractéristiques de l'invention ressortiront de la description d'un exemple de réalisation et du dessin-annesé qui représente les parties de commande d'un mécanisme unitaire de machine Dobby suivant la demande de brevet P 23 00 032. Other advantages and characteristics of the invention will emerge from the description of an exemplary embodiment and from the drawing which represents the control parts of a unitary mechanism of a Dobby machine according to patent application P 23 00 032.

Le releveur de platine 1, 1' d'une machine
Dobby est subordonné à la lame 2, 2', avant même le point d'inversion au moyen d'un ressort 3, 3', et lui est relié.
The platen lifter 1, 1 'of a machine
Dobby is subordinated to the blade 2, 2 ', even before the reversal point by means of a spring 3, 3', and is connected to it.

Ce mouvement est rendu possible du fait que le releveur de platine 1, 1' est libéré par un levier à deux bras 4, 4', comportant une roulette 5, 5' et au moyen d'un guide linéaire 6, 6', par l'intermédiaire du support 7, 7' commandé par un éleetro-aimant. Le guide linéaire 6, 6' actionné par une came qui n'est pas représentée, est pourvu d'une surface d'appui 8, 8' qui sert à établir le contact avec le support 7, 7'. Ce support 7, 7' est associé à l'élec tro-aimant 9, 9' et est commandé par lui suivant un programme. Le support 7, 7' peut tourner sur un axe, et sort en tournant de sa position de base contre la force d'un ressort 10, 10' sous l'action de l'électro-aimant 9, 9'.This movement is made possible by the fact that the plate lifter 1, 1 'is released by a lever with two arms 4, 4', comprising a roller 5, 5 'and by means of a linear guide 6, 6', by through the support 7, 7 'controlled by an electromagnet. The linear guide 6, 6 ′ actuated by a cam which is not shown, is provided with a bearing surface 8, 8 ′ which serves to establish contact with the support 7, 7 ′. This support 7, 7 'is associated with the electromagnet 9, 9' and is controlled by it according to a program. The support 7, 7 'can rotate on an axis, and exits by rotating from its basic position against the force of a spring 10, 10' under the action of the electromagnet 9, 9 '.

Le support 7, 7' est ajusté dans sa position de base par rapport au guide linéaire 6, 6', par la traction du ressort 10, 10'. L'ajustement du support 7, 7' est toujours exécuté après qu'il se soit formé un jeu entre la surface du guide linéaire et le support 7, 7'.The support 7, 7 'is adjusted in its basic position relative to the linear guide 6, 6', by the traction of the spring 10, 10 '. The adjustment of the support 7, 7 'is always carried out after a clearance has formed between the surface of the linear guide and the support 7, 7'.

Si, suivant le programme, il doit se produire une élévation d'une lame (non représentée), le support 7 7' reste dressé dans sa position de base et est poussé contre le guide alinéaire~6 6' par le ressort 10, 10'. Le guide linéaire 6, 6', actionné par une came qui n'est pas représentée par l'intermédiaire d'un levier 4, 4' à deux bras qui s'appuie sur la butée 12, 12', et par l'intermédiaire du support 72 71, commence à libérer le releveur de platine au moyen de sa roulette 5, 5'. Le releveur de platine 1, 1' tourne, sous l'effet du ressort, sur la lame 2, 2' avant même le point d'inversion.Après que la lame 2, 2' a atteint son point d'inversion et qu'il s'est formé un jeu entre la lame 2, 2' et le releveur de platine 1, 1', il se produit une adjonction immédiate du releveur de platine 1, 1' à la lame 2, 2', ce qui est une condition de la rapidité de la marche de la machine. Du fait de la rotation de la lame 2, 2', avec le releveur de platine qui lui est adjoint, dans sa seconde position terminale et au moyen de différents mécanismes, l'élévation de la lame s'effectue. If, according to the program, there must be an elevation of a blade (not shown), the support 7 7 'remains upright in its basic position and is pushed against the linear guide ~ 6 6' by the spring 10, 10 '. The linear guide 6, 6 ', actuated by a cam which is not represented by means of a lever 4, 4' with two arms which rests on the stop 12, 12 ', and by means of the support 72 71, begins to release the plate lifter by means of its wheel 5, 5 '. The plate lifter 1, 1 'turns, under the effect of the spring, on the blade 2, 2' even before the point of inversion. After the blade 2, 2 'has reached its point of inversion and that a clearance has formed between the blade 2, 2 'and the plate lifter 1, 1', there is an immediate addition of the platen lifter 1, 1 'to the blade 2, 2', which is a condition of the speed of operation of the machine. Due to the rotation of the blade 2, 2 ', with the platen lifter which is attached to it, in its second end position and by means of different mechanisms, the blade is raised.

Si, conformément au programme, il doit s'eèc- tuer une descente de la lame, l'électro-aimant 9, 9' fait tourner le support 7 7' en dehors de la surface d'appui du guide linéaire 6, 6'. Le levier à deux bras 4, 4' est ajusté par l'effet du ressort 13, 13', dans les positions de base sur la butée 12, 12', et au moyen de la roulette 5, 51, le releveur de platine 1, 1' est associé au support 14, 141. Le releveur de platine l, 1' retournant en commun avec la lame 2, 2' au point d'inversion est éloigné de la lame 2, 2' par la traction du ressort 13, 13' avant même ce point d'inversion, et après qu'il s'est formé un jeu entre le releveur de platine 1, Il et le support 14, 14' de la machine
Dobby, il se produit une commande immédiate et une adjonction de ce releveur vers le support 14, 14', ce qui est une condition pour la rapidité de la marche de la machine.
If, in accordance with the program, the blade has to descend, the electromagnet 9, 9 'turns the support 7 7' outside the bearing surface of the linear guide 6, 6 ' . The lever with two arms 4, 4 'is adjusted by the effect of the spring 13, 13', in the basic positions on the stop 12, 12 ', and by means of the wheel 5, 51, the plate lifter 1 , 1 ′ is associated with the support 14, 141. The plate lifter 1, 1 ′ returning in common with the blade 2, 2 ′ at the reversal point is moved away from the blade 2, 2 ′ by the traction of the spring 13, 13 'even before this reversal point, and after a clearance has formed between the plate lifter 1, Il and the support 14, 14' of the machine
Dobby, there is an immediate order and an addition of this lifter to the support 14, 14 ', which is a condition for the speed of the machine.

Par suite, la lame 2, 2' tourne dans une autre position sans le releveur de platine 1, 1', lui soit relié, c'est-à-dire que la foule est abaissée. La commande du support 7, 7' par l'électro-aimant 9, 9' est fixée dans le programme qui est emmagasiné dans une mémoire qui ntest pas représentée et d'où elle est reprise séparément pendant le fonctionnement de la machine.  As a result, the blade 2, 2 ′ rotates in another position without the platen lifter 1, 1 ′, being connected to it, that is to say that the shed is lowered. The control of the support 7, 7 'by the electromagnet 9, 9' is fixed in the program which is stored in a memory which is not shown and from which it is taken up separately during the operation of the machine.
