Definitions

  • the invention relates to a method and a device for sealing insulating glass blanks.
  • the sealing compound When sealing, i.e. when filling the edge joint of insulating glass blanks with sealing compound, the sealing compound is introduced into the edge joint from at least one filling nozzle that is moved along the edge joint of the insulating glass blank.

  • DE 29 07 210 A1 is a method of sealing Insulating glass blanks described in which the throttling of the supply of sealing compound always takes place simultaneously with the slowing down of the movement of the insulating glass blank.
  • the insulating glass blank is moved linearly with interruptions during the filling of edge joints parallel to the transport direction and the filling nozzle is moved transversely to the conveying direction when the insulating glass blank is stationary when edge joints aligned transversely to the conveying direction are to be filled.
  • the filling nozzle can be displaced on a beam which is oriented transversely to the conveying direction and which is attached to the machine frame in a non-adjustable manner in the conveying direction. This also applies to devices with two filling nozzles. Both known automatic sealing machines, the filling nozzle or the filling nozzles are not movable in the conveying direction of the insulating glass blank.
  • the one-nozzle sealing machine from Erdmann with the type designation " 7500 Series Vertical IG Secondary Sealer "is arranged in an insulating glass line of the type” Erdmann Vertical Insulating Glass (IF) Line "(cf. www.youtube.com/watch?v GlwRurxOtVo, uploaded 02.10.2010 ).
  • the automatic sealing machine has a supporting wall for insulating glass blanks, which is formed by several bars that are fixedly mounted in the machine frame and equipped with freely rotating rollers.
  • Linear conveyors in the form of conveyor belts with lateral guide rollers (on the inlet side) and in the form of conveyor rollers (on the outlet side) are provided at the lower edge of the support wall. The linear conveyor on the inlet side is lowered when sealing is carried out.
  • suction heads are provided as holding devices for the insulating glass blank to be sealed, which can be adjusted back and forth across the supporting wall.
  • the suction heads can be placed on an insulating glass blank to be sealed.
  • the insulating glass blank is held exclusively by the suction heads, which are arranged in the supporting wall, so that the edges of the insulating glass blank are free and the sealing nozzle can be moved around the insulating glass blank along the four edges, while in the edge joint of the insulating glass blank sealing compound is filled.
  • a support finger is assigned to each suction head.
  • the support fingers can independently of one another from a horizontal pivot axes Ready position can be pivoted into an approximately horizontal effective position.
  • a support finger is swiveled up from below in contact with the lower edge of the insulating glass blank.
  • the support finger is pivoted downwards when the sealing nozzle moves along the lower edge of the insulating glass blank during sealing.
  • the problem with the known methods for sealing and with the devices proposed for this purpose is that because of the filling nozzle / filling nozzles which cannot be adjusted or displaced in the conveying direction, moving the insulating glass blank through a sealing station when sealing edge joints that are transverse to the direction of movement of the insulating glass Blanks run, interrupted and must be resumed. This extends the cycle time because the insulating glass blank is slowed down and accelerated. This problem occurs particularly with large and heavy insulating glass blanks.
  • US 2015/0354266 A1 shows and describes a method and a device for producing insulating glass, comprising a device for attaching a spacer to a glass pane and a device for filling the edge joint of an insulating glass blank with filler (sealing station).
  • a filling nozzle on a bar can be adjusted transversely to the conveying direction of the insulating glass blank in order to seal sections of the edge joint of the insulating glass blank that are oriented transversely to the conveying direction.
  • the bar itself can also be adjusted in the conveying direction so that it can be moved further together with an insulating glass blank so that space is created for the removal of another insulating glass blank.
  • US 2015/0354266 A1 does not disclose that an insulating glass blank is moved in the conveying direction when sections of the edge joint of the insulating glass blank that are oriented transversely to the conveying direction are sealed will.
  • the in US 2015/0354266 A1 The reference to a continuous movement of the insulating glass blank is intended to mean that the insulating glass blank never has to be moved against the direction of conveyance, as shown in US 2015/0354266 A1 , Paragraph [0074] is expressly mentioned.
  • the invention is based on the object of designing the sealing of insulating glass blanks in such a way that the disadvantages that occur during sealing due to the braking and acceleration of insulating glass blanks are no longer present.
  • the basic idea of the invention is that the at least one filling nozzle is moved during the sealing, in particular at least during individual sections of the sealing, parallel to the direction in which the insulating glass blank is moved during the sealing.
  • the filling nozzle can be moved in the same direction as the insulating glass blank to be sealed or in the opposite direction.
  • One possible embodiment of the method according to the invention provides for the insulating glass blank to be sealed to be moved continuously during sealing, the at least one filling nozzle with the insulating glass blank being moved when the direction of movement (conveying direction) of the insulating glass blank non-parallel areas of the edge joint of the insulating glass blank are sealed.
  • the insulating glass blank is (briefly) stopped during sealing.
  • Such a case exists, for example, when long (large) insulating glass blanks are to be sealed in the conveying direction.
  • the area in which the filling nozzle can be moved in the conveying direction can be too short, so that the filling nozzle arrives at the end of its movement range before the section of the edge joint of the insulating glass blank that is oriented transversely to the conveying direction and is to be filled with sealing compound filled (sealed).
  • the method according to the invention usually allows the insulating glass blank, according to a preferred embodiment of the method, to be moved continuously in the conveying direction, if necessary at different, high speeds.
  • the possibility provided according to the invention also allows the filling nozzle to be moved in the conveying direction, so that with small insulating glass blanks only the filling nozzle is moved and the insulating glass blank is not moved or only moves slightly in the conveying direction.
  • the speed with which the filling nozzle is moved in order to adapt it to the prevailing circumstances (size of the insulating glass blank, cross-sectional size of the edge joint of the insulating glass blank).
  • the speed of the movements of the filling nozzle both in and across the conveying direction does not have to be be constant, but can also be changed within the scope of the invention during a sealing process.
  • the possibilities allow not only to change the speed at which the insulating glass blank is moved (in the conveying direction), but also to change the speed at which the filling nozzle is moved, in particular to change it independently of one another, so that cycle times optimized and the (horizontal) dimensions of the sealing station can be reduced without the advantages of the invention being lost.
  • Another advantage of the invention consists in adapting the cycle times of the method according to the invention and the device according to the invention to the capacities of upstream and downstream system parts without adversely affecting the quality of the sealing of insulating glass blanks.
  • the required relative movement between the filling nozzle and the insulating glass blank can be achieved by moving only the insulating glass blank or by both move the insulating glass blank and the filling nozzle in the conveying direction at different speeds.
  • the filling nozzle When filling sections of the edge joint that are parallel to the conveying direction, the filling nozzle is not moved transversely to the conveying direction. When “inclined” or “curved” sections of the edge joint are to be filled with sealing compound, the filling nozzle is moved transversely to the conveying direction in order to follow the "inclined” or “curved” section of the edge joint.
  • An advantage of the method of operation proposed according to the invention when sealing insulating glass blanks is that the sluggish regulation of the amount of sealing compound that is dispensed from the filling nozzle into the edge joint per unit of time is achieved by the quick regulation of the speed of the movements of the filling nozzle and / or of the insulating glass blank can be compensated.
  • Another advantage of the method according to the invention and the device according to the invention is that the movements of the insulating glass blank required in the prior art without it being sealed ("empty runs") in order to correctly align it for sealing relative to the at least one filling nozzle , are dispensable.
  • the insulating glass blank, while it is being sealed is moved continuously in the conveying direction.

  • the at least one Filling nozzle when introducing sealing compound into sections of the edge joint aligned transversely to the conveying direction at the same speed V 2 as the insulating glass blank is moved in the conveying direction and additionally transversely to the conveying direction.
  • the at least one filling nozzle in addition to its movement parallel to the conveying direction, is moved transversely to the conveying direction when introducing filling compound into sections of the edge joint that enclose an angle to the conveying direction.
  • a single filling nozzle is used, from which sealing compound is successively introduced into all sections of the edge joint of an insulating glass blank.
  • the at least one filling nozzle when the sealing compound is introduced into a section of the edge joint aligned parallel to the conveying direction, is moved in the conveying direction at a speed V 2 , which is dependent on the speed V 1 of the movement of the insulating glass
