Definitions

  • the invention relates to a system for producing insulating glass panes with the features specified in the preamble of claim 1.
  • a system for producing insulating glass panes with the features specified in the preamble of claim 1.
  • Such a system is known from EP 0 176 388 A1.
  • the known system has a horizontal conveyor for glass panels formed from several sections. In each section there is a horizontal stand-up conveyor, for example a line of synchronously driven rollers, on which the glass panels stand upright, whereby they are attached to a support device, in particular lean against a support wall which extends laterally above the erecting conveyor and determines a running level for the glass panels.
  • a nozzle which can be moved up and down parallel to the common axis of the support rollers and can be rotated about an axis passing through its mouth, which is perpendicular to the plane of the disk running.
  • the nozzle is mounted on a carriage which is guided on a column which is set up in front of the horizontal conveyor and is parallel to the plane of the disc.
  • the nozzle is fed with a plastic of a viscous-pasty nature, in which a drying agent is stored, which is able to bind moisture.
  • the plastic is a synthetic butyl rubber (a polyisobutylene).
  • the plastic is fed to the nozzle by means of a gear pump, which is arranged closely behind the nozzle.
  • the nozzle is moved along the edge of a glass sheet and thereby applies a plastic strand to the glass sheet along its circumference.
  • the cross section of the strand thus formed depends on the cross section of the nozzle opening, the flow rate of the plastic, the relative speed between the nozzle and the glass sheet, and on the toughness of the plastic.
  • the relative speed between the nozzle and the glass sheet and the throughput are maintained the plastic expediently constant.
  • a sensor In a forward position of the piston in the intermediate store, a sensor responds, which switches on a barrel pump, whereupon the nozzle pumps plastic through the hollow piston into the intermediate store, so that the piston withdraws until another sensor responds in a rearward piston position and the barrel pump again switches off. In this way, an uninterrupted operation with a constant inlet pressure for the gear pump is possible until the drum is empty.
  • the movement of the nozzle along the edge of the glass sheet takes place through an interplay of the movement of the nozzle in the vertical direction and the movement of the glass sheet on the horizontal conveyor in the horizontal direction as it is is also known for devices for automatically sealing the edge joint of already assembled insulating glass panes (DE-B-28 16 437 and DE-B-28 46 785). Then a spacer made of plastic can be applied to a glass sheet along its circumference by moving the glass sheet on the horizontal conveyor until it lies with its front, vertical edge in front of the support rollers, where it is stopped.
  • the nozzle In the case of glass panels which have an outline shape which deviates from the rectangle (so-called model disks), the nozzle is moved along the edges which are not parallel or perpendicular to the direction of travel of the horizontal conveyor by the drive of the horizontal conveyor and the drive for the vertical movement of the nozzle simultaneously and through Position sensors or program-controlled are coordinated.
  • a plastic strand to form a plastic-based spacer is applied along the entire circumference to a glass sheet, then this glass sheet is conveyed by means of the horizontal conveyor into an assembly and pressing station equipped with two parallel pressing plates, there a second, equally large glass sheet Positioned congruently opposite one another and connected to it by moving the pressure plates towards one another and pressed (calibrated) to a predetermined thickness of the insulating glass pane.
  • the edge joint existing on the outside of the spacer is then sealed with another plastic (usually with a hardening polysulfide) (DE-B-28 16 437, DE-B-28 46 785).
  • the system Before the section in which a plastic-based spacer is applied to a glass sheet, the system usually has a glass sheet washing machine with a subsequent drying zone and an intermediate transport path, which essentially consists of a horizontal conveyor with or consists of several sections.
  • Both glass panels which are assembled into an insulating glass pane, first pass through the washing machine.
  • the first of the two glass sheets runs through the section of the system in which the spacer is formed without a stop and, while the spacer is applied to the subsequent second glass sheet, is already in the assembly and pressing device for later assembly with the subsequent one Glass panel positioned.
  • the production performance of a production line for the production of insulating glass panes is determined by the slowest working station in the production line. In the present case, this is the section in which the plastic-based spacer is produced.
  • the working speed in this section cannot be accelerated arbitrarily for physical and technical reasons. An increase in the working speed would require an increase in the throughput of the pasty plastic through the nozzle. This in turn would require lowering the viscosity by increasing the temperature; however, there are narrow limits in that, with decreasing viscosity, the extruded strand applied to the glass sheet is no longer dimensionally stable, but changes its shape by flowing under the influence of gravity, which cannot be accepted for its use as a spacer.
  • the present invention has for its object to show a way, such as the working speed in the system can still be increased.
  • the system according to the invention is operated as intended so that the first glass sheet is one Pair of glass panels runs into the middle section of the horizontal conveyor and there is provided with the spacer from the nozzle; while this is happening, there is sufficient time around the second, subsequent glass sheet of the pair of glass sheets with the aid of the second glass sheet running plane around the first glass sheet being processed to lead around; This is served by the first subsection and the second subsection of the horizontal conveyor, which for this purpose can be moved parallel to itself from the first glass panel running level to
  • the first subsection of the horizontal conveyor is shifted from the first glass panel running level to the second glass panel running level; before, simultaneously or shortly thereafter, the second subsection is also moved from the first glass panel running level to the second glass panel running level.
  • the second glass sheet is then transferred from the first subsection to the second subsection by driving the horizontal conveyor in the second glass sheet running level and stopped there again.
  • the first subsection and the second subsection are then moved back into the first glass sheet running plane and, while the first glass sheet is being processed in the middle subsection, the second glass sheet is conveyed into the assembly and pressing device to be positioned there.
  • the first subsection is now ready to accept the first glass sheet of the next pair of glass sheets, so that as soon as the first glass sheet of the previous pair of glass sheets in the middle subsection has been finished and is transported to the assembly and pressing station, it will enter the middle subsection without delay to be provided with the spacer, with which the next Machining cycle begins.
  • the time required for the passage of a glass sheet of a pair of glass sheets can therefore be completely saved in the cycle time of the system.
  • the outlay on equipment required for this is comparatively low: only two subsections of the horizontal conveyor, which are present in any case, need to be designed to be transversely displaceable and linked in the second glass table running level by an additional horizontal conveyor, which is just as long as the middle subsection in the first disc running plane, in which the spacer is located is formed. No processing takes place in the second disc running plane, only conveying. Since most sections of the horizontal conveyor are already available in modular form in an insulating glass production line, the solution according to the invention does not require any additional development and construction effort.
  • the additional equipment required according to the invention is far exceeded by the increase in productivity of the production line.
  • the first and second subsections of the horizontal conveyor are expediently approximately the same length and approximately half as long as their mutual distance; you can then move the same glass sheet formats across, which are simultaneously provided with the spacer on the middle subsection of the horizontal conveyor (if only one nozzle is used, which can only be moved up and down and rotated, a glass sheet must be in full length before and during application of the spacer in the middle subsection of the horizontal conveyor can also be moved back).
  • the additional outlay on equipment required according to the invention is particularly low if the first and second subsections are only about two meters long and the intermediate subsection is only about four meters long. Then the vast majority of the glass panels, in which the length of an edge does not exceed two meters, can be processed in the manner described, in which one of the two glass panels of a pair of glass panels is guided over the second glass panel running level.
  • the small proportion of glass panels can be processed in the system according to the invention in a conventional manner by not moving the first and second subsections of the horizontal conveyor, but rather in the first glass panel running level lets stand and the first glass sheet of a pair of glass sheets without stopping through the middle subsection in the assembly and pressing station and the subsequent second spacer provided with the spacer; Since the processing time in such large dimensions in the other stations of the production line, in particular in the sealing station, is longer than in the case of smaller formats, the longer cycle time is not particularly significant due to the conventional processing of the large formats.
  • first and the second subsection of the horizontal conveyor are each provided twice, namely at a distance from one another parallel to the two glass panel running levels.
  • first and second subsections of the horizontal conveyor can be conveyed simultaneously in both disc running planes.
  • the transverse displacement of the two subsections parallel to one another is expediently carried out by a common drive.
  • the second glass panel running level preferably runs behind the first glass panel running level in order not to impair the accessibility of the front of the first glass panel running level in the region of the central subsection where the spacer is applied.
  • the section of a production line shown shows a section 1 of a horizontal conveyor, consisting of a first subsection 2, a middle subsection 3 and a second subsection 4.
  • the middle subsection 3 is composed of three successive parts, namely a part 5 on the inlet side, one middle part 6 and a discharge-side part 7.
  • the horizontal conveyor 1 has a horizontal stand-up conveyor 8 and support walls 9 extending in a common alignment, which extend laterally above the stand-up conveyor 8 and are inclined rearward by approximately 6 °, so that glass panels placed on the stand-up conveyor 8 lean against the support walls 9 can.
  • the erection conveyor 8 is formed by synchronously drivable rollers 10, the axes of which are oriented perpendicular to the support walls 9.
  • the stand-up conveyor is formed by two endless conveyor belts 11.
  • the support walls 9 are air cushion walls; they have openings from which air escapes, which comes from a blower 12 on the back of the support walls and generates an air cushion between the front of the support walls 9 and an attached glass sheet, on which the glass sheets can slide gently and tilt-proof.
  • a plurality of horizontally running suction conveyor belts 12 which are arranged at a distance from one another and which are driven synchronously with the conveyor belts 11 in the support wall 9.
  • the suction conveyor belts 12 suck in the glass sheets and thereby ensure an absolutely slip-free movement in this area.
  • Suitable suction conveyor belts are disclosed in DE-A-35 29 892 and EP-0 225 429.
  • a nozzle 13 Opposite the middle part 6 of the horizontal conveyor, a nozzle 13 is arranged, which can be moved up and down on a column 14, which stands in front of the middle part of the horizontal conveyor and, like the support walls 9, is inclined slightly backwards so that it is parallel to the Retaining walls runs.
  • a piston-cylinder unit 15 is moved up and down on the column 14, which contains the plastic-based material from which the spacer for the insulating glass is formed.
  • the nozzle is fed from the piston-cylinder unit 15 by advancing the piston of the piston-cylinder unit. In order to achieve exact quantity dosing of the material, the movement of the piston is controlled with the help of a displacement sensor.
  • the piston-cylinder unit 15 is provided twice, and the two units are Operated alternately: While one unit dispenses, the other is refilled.
  • a movable supply line 16 which can be switched by means of a rotary slide valve, is provided, which leads from a barrel pump 17, which is arranged on a barrel 18, to the piston-cylinder units 15.
  • the drum pump 17 can have the structure described in EP-0 171 309 B2.
  • a second horizontal conveyor 21 consisting of two identical sections 22 and 23, which are located exactly behind the middle subsection 3 of the first horizontal conveyor and, taken together, are as long as this.
  • sections 22 and 23 correspond to the first subsection 2 and the second subsection 4 of the front horizontal conveyor.
  • the front sides of the support walls in sections 22 and 23 define a second, rear glass panel running level.
  • Sections 2 and 24 are firmly connected to one another at their predetermined distance and can be moved together on rails 26 transversely to the glass panel running plane.
  • the subsections 4 and 25 are firmly connected to one another and transversely on rails 27 can be moved together to the glass panel running level. The shift takes place between a first position, shown in FIG.
  • the nozzle 13 applies the plastic spacer to the first glass sheet, the nozzle 13 and the glass sheet moving relative to one another, as described at the beginning.
  • the processing in the middle subsection 3 may be most advantageous to convey the first glass sheet from the middle subsection 3 via the section 25 in its forward position into the assembly and Press station and over the first subsection 2 in its rear position to run the first glass sheet of the subsequent glass sheet pair into the middle subsection 3.
  • the processing time of which in the middle subsection 3 is correspondingly longer there may be sufficient time to shift sections 25 and 4 into their rear position and sections 24 and 2 into their front position before the glass sheet processed in the middle subsection 3 removed and the first glass sheet of the next pair of glass sheets is conveyed into this subsection 3.
