Title
(EN) APPARATUS FOR VERIFYING THE PRESENCE, OR THE ABSENCE, OF AN ABRASIVE ELEMENT IN A MACHINE FOR WORKING SURFACES
(FR) APPAREIL PERMETTANT DE VÉRIFIER LA PRÉSENCE OU L'ABSENCE D'UN ÉLÉMENT ABRASIF DANS UNE MACHINE POUR LE TRAITEMENT DE SURFACES
Abstract
(EN)
An apparatus (100) for verifying the presence, or the absence, of an abrasive element (20) in a machine (1) for finishing surfaces comprising a support body (10) configured to removably engage the abrasive element (20). The support body (10) and the abrasive element (20) are, respectively, provided, at respective engagement surfaces (15, 25) with first and second engagement elements (13, 23) configured to move from an engagement configuration to a disengagement configuration, and vice versa. Furthermore, a displacement device (40) is provided to move the support body (10) in the space according to at least 1 degree of freedom. The apparatus, furthermore, provides at least a control station (250) equipped with a control device (70) comprising a control element (75) having a control surface (76) provided with third engagement elements (73) configured to engage with the first engagement elements (13) of the support body (10), and a detection device (80) configured to detect if an engagement between the control element (75) and the support body (10) has taken place.
(FR)
La présente invention concerne un appareil (100) permettant de vérifier la présence ou l'absence d'un élément abrasif (20) dans une machine (1) pour la finition de surfaces, comprenant un corps de support (10) conçu pour venir en prise de manière réversible avec l'élément abrasif (20). Le corps de support (10) et l'élément abrasif (20) sont respectivement pourvus, au niveau de surfaces de mise en prise respectives (15, 25), de premiers et deuxièmes éléments de mise en prise (13, 23) conçus pour se déplacer d'une configuration de mise en prise à une configuration de séparation et inversement. En outre, un dispositif de déplacement (40) est prévu pour déplacer le corps de support (10) dans l'espace selon au moins 1 degré de liberté. L'appareil comprend en outre au moins une station de commande (250) équipée d'un dispositif de commande (70) comprenant un élément de commande (75) ayant une surface de commande (76) pourvue de troisièmes éléments de mise en prise (73) conçus pour venir en prise avec les premiers éléments de mise en prise (13) du corps de support (10), et un dispositif de détection (80) conçu pour détecter si une mise en prise entre l'élément de commande (75) et le corps de support (10) a eu lieu.
