摘要:
Recording papers (P) stacked up on a tray (45) are conveyed as being attracted with vacuum by the conveying belt (98) located above or beneath. To convey the recording papers (P) one by one, air flow (C) is blown to the front edges of the recording papers (P) to separate them. Accordingly, plural nozzles (96) are disposed in the widthwise direction of the recording papers (P), and the air flows (C) from the nozzles (96) are directed to converge at the upstream side of the conveying direction (A2). By setting this converging position near the both ends in the widthwise direction of the recording papers (P), the recording papers (P) may be separated securely and stably.

The apparatus (38) comprises a laying plate (149) on which sheets (P) are stacked up; feeding means (220) disposed above the sheets (P) for vacuum attracting, partly deforming in the widthwise direction and feeding the top sheet (P1); and air flow forming means (168) for injecting an air flow (D) toward the deformed parts of said top sheet (P1).

Le dispositif concerne une table (1) d'aspiration qui, dans une machine de travail de feuilles pour la production d'emballages, transfère la dernière feuille inférieure d'un paquet à une station suivante de travail. La table (1), munie de nombreuses buses (3,4) d'aspiration et de souffage, est montée sur un bâti creux (B) mobile par rapport à un carter fixe (2) de distribution d'aspiration et de pression. Le carter (2) comprend un arbre de distribution (D) et des tubes (T₁) pouvant coulisser à l'intérieur de guidages correspondants (G₁) prévus dans le bâti (B). Tous ces éléments sont munis de conduits (10, 11, L₁, L₄, R p , R₃, O₃, 100, S₁) qui, en fonction de la position angulaire de l'arbre de distribution (D) et de la position de la table (1), permettront de mettre les buses (3,4) sous aspiration ou pression.

The integrated, automated composite material manufacturing system for pre-cure processing of preimpregnated composite materials, and particularly, for one-sided preimpregnated composite materials includes a computer control subsystem (150) for controlling and synchronizing the pre-cure processing operations, a material cutting station (20) for controlled cutting of preimpregnated composite materials into individual composite plies (GP) of predetermined size and shape based upon composite ply configurations stored in the computer control subsystem (150), a ply unloading station (30) for providing automatic pickup, transfer and placement operations to unload the individual composite plies (GP) utilizing a multiplicity of bi-functional transfer feet that are automatically, selectively activated to form a predetermined combination operative to engage and retain and disengage and release the tacky surface of individual composite plies (GP), a ply transfer subsystem (50) automatically operative to transfer composite plies (GP) between the unloading subsystem (30) and a ply inverting subsystem (60) for rotating individual composite plies (GP) to place the non-tacky surface up, a ply transfer/layup subsystem (90) to transfer composite plies (GP) to a composite article mold having a mold surface and to layup the transferred composite plies (GP) on the mold surface, and a ply conforming subsystem (110) for conforming said layed up composite plies (GP) with the mold surface.
摘要:
A reciprocating vacuum shuttle plate co-operates with a knife gate (112) and high-friction rollers (118,120) positioned between the knife gate (112) and an additional conveyor formed by a driven feed roller (94) and an idler feed roller (96). The high-friction rollers (118,120) form a singulator gap (188) with shoulders (184) of a vacuum-groove (186) on a sheet-engaging surface of the reciprocating shuttle plate. The knife gate (112) holds back other sheets in the stack and the singulator separates any double sheets which pass the knife gate (112). A transition tray downstream of the additional conveyor provides a transition to clamps of an endless chain. The transition tray comprises an endless conveyor belt with a floating feed roller biased thereagainst. The position of the floating feed roller can be adjusted so as to space it approximately a sheet length from a stationary clamp on the endless chain. The shuttle plate comprises upper panels one of which is a vacuum-groove panel which can be interchanged with one another on a shuttle plate frame so that the position of the vacuum-groove panel can be changed. A thumb mechanism provides resistance to falling sheets so that a forward-most sheet has reduced pressure on it.

Tête de dépilage, pour l'extraction un à un d'une pile notamment horizontale, d'objets plats (2) disposés verticalement, comportant un bras pivotant (18) muni d'une courroie mobile et perforée (7), guidée et tendue entre deux rouleaux (9,10) à axes parallèles et verticaux (11,12) pouvant occuper respectivement deux positions où, dans l'une la courroie du bras est en contact avec le premier objet de la pile s'étendant sensiblement parallèlement à la courroie et dans l'autre le bras est dégagé de la pile. Selon l'invention, cette tête se caractérise en ce que le bras pivotant comporte, montée à l'intérieur de la courroie entre les rouleaux, une cage parallélépipédique ( 21 ), ouverte sur l'une de ses faces verticales dirigée vers le premier objet de la pile au contact de la courroie mobile, cette cage étant raccordée à ses extrémités haute et basse (22,23) démunies de fonds par un conduit de liaison (27) avec une tubulure d'aspiration (34), propre à créer dans la cage et à travers la courroie perforée, une dépression attirant le premier objet, ainsi plaqué contre la courroie et entraîné avec celle-ci.
