Definitions

  • This invention relates to an arrangement in a glass bending furnace in accordance with the preamble of claim 1 by means of which arrangement formation of glass sheet unloading and glass sheet loading times are prevented as capacity restricting factors .
  • the circulation time of carriage vertical motions including horizontal motions, lift motions, function of side members etc. typically take ab. 30 sec. Then the carriage is immobile in the lower part of said loading lift depending on the capacity of furnace each time. For instance, at a capacity of n pieces/h the time of standing still is (3600 sec) /n - 30 sec.
  • Fig. 1 is a schematic side view of a furnace embodiment.
  • Fig. 2 is schematic view of a furnace embodiment from above furnished with the arrangement as per this invention.
  • Figure 1 shows a serial furnace from one side, which has an upper rail 3 and an lower rail 4.
  • Glass sheet 9 for bending travels in mould carriage 8 on the upper rail from section 2a to another section 2b, 2 c etc.
  • the glass sheet On the upper rail the glass sheet is heated up to bending temperature.
  • the lower rail bent glass sheets 10 travel in mould carriage 8 via cooling sections to the unloading and loading end, which comprises also the lift section.
  • each mould carriage 8 stops in the respective section. The cycle includes the transmission time of one carriage and the stop time of one carriage .
  • Figure 2 shows the furnace from above.
  • bent glass sheets 10 travel in mould carriages 8 in turns to section 2a.
  • the mould with bent glass sheet 10b is shifted over to lift section 1, when carriage 8a with straight glass sheet 9d in the mould has been first elevated by the lift to upper rail 3.
  • the transmitter whose turn it is, e.g. device 5, collects glass sheet 10b and the mould pulling them to the side station onto transmitter 5.
  • the bent glass sheetlO is removed into pile 10.
  • a straight glass sheet from pile 9 is mounted in the mould as replacement .
  • transmitter 6 brings the mould and new glass sheet 9e to mould carriage 8b.
  • Carriage 8b is elevated by the lift and the arrangement is ready to receive and move the next mould carriage 8c to section 1 regardless of whether on the rail a transmission cycle is unfinished or not.
  • Transmitter 6 that has lastly brought a glass sheet takes the from first at section 1 arrived carriage 8c a mould and a glass sheet 10c and pulls the glass sheet aside for replacement.
  • mould carriage 8c is empty in section 1 and transmitter 5 brings the mould and a new glass sheet 9f into it.
  • mould carriage 8d arrived at least at section 2b during the transmission cycle, is moved to section 1 and transmitter 5 picks up mould and glass sheet lOd.
  • the transmitter that has lastly brought the mould and straight glass sheet to section 1, also takes the next at the section arrived bent glass sheet for transmission to the respective side station.
  • the transmitters can, each in its turn, keep each mould aside for a longer time for glass sheet replacement.
  • section 2b is empty on the lower rail at the moment shown.
  • One advantageous embodiment of the invention is that from section 2c the mould carriage travels forward still steered by the transmission cycle, i.e. pushed by the other carriages, but the carriage arrived at sections 2a and 2b or at least at section 2a is steered forward regardless of the transmission cycle. These carriages are moved in turns to lift section 1 substantially at once when the lift section is empty.
  • the next carriage for instance 8d, can freely enter the empty section not causing any forced transmission to the lift section in the arrangement as per this invention.
  • transmitters 5 and 6 are fork trucks with forks lifting the mould and taking it to the side station.
  • the side stations comprised in this invention bring about a remarkable growth of capacity.
  • the furnace construction includes a control centre 11 to steer the furnace operation.
  • the control of the timing of transmitter 5 and 6 functions can be made automatic and synchronous with the shit over of mould carriages from section 2a to section 1.

Abstract

L'invention concerne un agencement à l'extrémité du déchargement et chargement d'un four de bombage de verre à plusieurs sections, plus précisément un four dans lequel les feuilles de verre (9, 10) voyagent, le long d'un rail spécial, d'une section à la suivante dans des porte-moules (8) se déplaçant de façon cyclique sur ledit rail. Pour charger et décharger le verre bombé (10) du moule, ce dernier est déplacé dans le porte-moule (8) du rail au premier poste latéral et du second poste latéral, le moule contenant la feuille de verre (9) est déplacé dans ledit porte-moule, tandis que ledit porte-moule continue de se déplacer sur le rail. Aux deux postes latéraux, la feuille de verre bombée est retirée du moule et remplacée par une nouvelle feuille de verre (9). Dans chaque poste latéral, un élément de transmission des moules recueille les moules de la même section et les renvoie à la même section du four.
