Definitions

  • the invention relates to an arching-ready support assembly in a bending and/or tempering compartment for glass panels, said support assembly comprising a number of link bodies, which are connected to each other with articulated axles, and control link mechanisms present between the link bodies, which control arching of the support assembly to a constant-radius curve.
  • This type of support assembly is known from the Applicant's patent publication EP-I 385 795. This support assembly has proved highly useful.
  • An object of the invention is to improve this support assembly further so as to enable the arching of even long support assemblies to a precisely constant-radius curvature by means of simple and inexpensive actuators without the link gaps becoming an adverse factor or even to enable using the link gaps for providing very slight intentional curvature deviations.
  • Fig. 1 shows a support assembly of the invention and its arching apparatus in a side view
  • Fig. 2 shows more closely a portion of the support assembly in a side view
  • Fig. 3 shows the support assembly of fig. 2 in a straightened configuration.
  • Fig. 1 shows, on the left-hand side of a vertical line 6, a bending conveyor's support assembly 4 and, on the right-hand side, a tempering conveyor's support assembly 5.
  • the support assemblies 4, 5 are associated with each other without a mechanical coupling at an articulation point 6a, whereby the support assemblies 4 and 5 can be disengaged from each other as desired.
  • the articulation point 6a between the support assemblies 4 and 5 remains stationary, whereby the support assembly's 4 upstream end and the support assembly's 5 downstream end can be lifted and lowered for bringing the support assembly to a desired curvature and to a straight configuration.
  • the support assemblies 4 and 5 enable supporting the conveyor rolls of a bending conveyor and a tempering conveyor.
  • the support assemblies 4 and 5 include link bodies 9 present on the sides of the conveyors, i.e. at both ends of the rolls, which are provided with bearings for the conveyor rolls.
  • the link bodies 9, on the other hand, are connected to each other by a link mechanism shown in figs. 2 and 3, which forces the link bodies 9 to pivot relative to each other to an equal extent as the support assembly 4, 5 is being arched.
  • the link mechanism associated with each link body 9 includes three articulated arms 1, 2, 3, which couple each time three link bodies 9 with each other, such that the link bodies 9 are forced to pivot to a mutually equal extent, whereby the entire support assembly arches to a constant- radius curvature.
  • the disposition of articulation points for the articulated arms 1, 2, 3 has been described in more detail in patent publication EP-I 385 795 (Bl) and, hence, not discussed further in this specification.
  • Fig. 1 shows a servomotor 10, which by way of a clutch operates a ball screw 10a, which in turn pushes and/or pivots a lever system 11, upon which rests the support assembly established by the link bodies 9.
  • the support assembly 4 has its radius of curvature Rl adjustable by means of the servomotor 10.
  • the arching mechanism for the tempering conveyor's support assembly 5 includes a servomotor SMl and a ball screw 12a operated thereby, which, through the intermediary of arms 12b, arches a bridge established by the link bodies 9 and thereby an entire conveyor carried by the support assembly 5.
  • the arms 12b engage the support assembly 5 at a small distance from its ends.
  • a second servomotor SM2 uses a herringbone gear 16 to operate ball screws 17, which engage the support assembly 5 at its opposite outer ends.
  • the servomotors SMl and SM2 are operatively synchronized by means of an electrical gearbox to enable arching the support assembly 5 to the same radius of curvature.
  • the arching-ready support assembly 5 has its first section in the support assembly's middle portion and its second section in the support assembly's end portions.
  • the discussed support assembly 5 is preferably a tempering conveyor's support assembly, which is typically longer than the bending conveyor's support assembly 4.
  • the tempering conveyor's support assembly 5 is preceded by the bending conveyor's support assembly 4, which has its own separate servo drive 10, 10a, 11 for arching the support assembly 4 to a constant-radius curvature Rl.
  • the gaps of the link mechanisms can be controlled also in this instance in such a way that the support assembly 4 can always be arched with a desired radius of curvature.

Abstract

L'invention concerne un ensemble support prêt à incurver (5) dans un compartiment d'incurvation et/ou de trempe de panneaux de verre. Cet ensemble support comprend un certain nombre de corps de liaison (9), qui sont connectés entre eux par des axes articulés (9a). Entre les corps de liaison (9) des mécanismes de liaison de commande (un, deux, trois) commandent l'incurvation de l'ensemble support (5) selon une courbe de rayon constant. Une première section de l'ensemble support (5) est conçue pour être incurvée par un premier servomoteur (SM1) et une seconde section est conçue pour être incurvée par un second servomoteur (SM2).
