Definitions
- the invention relates to a method for producing an insulating glass pane and to a device for applying a spacer to a glass pane having the features of the preamble of the independent claims.
- insulating glass panes are produced in which a spacer with a rectangular cross-section is mounted between two panes of glass.
- spacers are known in band form.
- Such spacers are already filled in their preparation with a desiccant and preferably stored on a reel or in a storage container.
- the drying agent is used to dehumidify the air space between two panes of glass and to ensure long-term dew point of -70 0 C if possible.
- WO 2005/078227 describes, for example, the production of such an insulating glass pane by means of a completely prefabricated spacer.
- the spacer is made of a foamed material, which is also provided with a drying agent.
- the spacer with the desiccant is stored in a storage container until it is needed for the installation of the insulating glass pane.
- the spacer and two glass panes are joined together to form an insulating glass pane.
- EP 1347142 B1 describes a device for automatically applying elastoplastic spacers to a glass pane. The spacer is unwound from a storage drum and transported without tension to the application.
- the known methods have the disadvantage that the drying agent is already introduced into the spacer during the production of the spacer. As a result, the drying agent can absorb moisture in an uncontrolled manner during storage of the spacer. When mounting the insulating glass is thus not known which remaining capacity for receiving moisture drying agent still has. In addition, neither the amount nor the type of desiccant can be selected for a particular spacer in the production of insulating glass.
- the method comprises the steps:
- the drying agent is introduced during or after the application of the spacer to the first glass pane.
- the spacer is made of such a flexible material that can be adjusted according to the contour of the glass.
- the spacer is made of silicone or similar flexible and UV resistant & fogging disciplineeren material. Foamed plastics for the spacer can preferably also be used.
- the spacer serves as a carrier for the desiccant.
- the term "during application” is to be understood as meaning that about the same time as the spacer is applied or immediately before the spacer is applied, the drying agent is also introduced into or onto the spacer in the same operation During this continuous application, the spacer is also continuously provided with desiccant
- the addition of the desiccant can occur anywhere on the path of the spacer to the glass pane at an opening of a storage container for the removal of Standhalter be applied.
- the desiccant is added to the spacer by means of a suitable device immediately upon application of the spacer to the glass sheet.
- a device for applying the spacer has an applicator head, which on the one hand automatically attaches the spacer in an edge region of the glass pane and at the same time provides the spacer with desiccant.
- the drying agent is applied to the glass plate only after the application of the spacer.
- the spacer is then already at least partially connected to the glass, for example by means of a butyl adhesive.
- An end face of the glass pane can then also serve as a guide aid for a suitable device for applying the drying agent.
- the bonding of the two glass panes with the spacer takes place in a known manner, preferably by means of adhesives. This process is known and will therefore not be explained further here.
- the drying agent is inserted into at least one cavity of the spacer.
- the spacer preferably forms a longitudinally extending cavity profile.
- the spacer may also be formed as an open profile, wherein - instead of the cavity - a recess on a surface of the spacer is provided, in which the desiccant is applied.
- the drying agent becomes applied in at least one closed cavity of a cavity profile.
- the cavity for filling the drying agent is opened substantially along its longitudinal direction.
- the cavity profile can either be completely closed, so that the cavity profile must be separated or cut open to open the cavity.
- the cavity profile is obvious, in particular has a longitudinal slot which is already mounted in the production of the cavity profile and which is closed by the internal stress of the profile. In this case, to apply the drying agent, it is sufficient to pull apart the cavity profile so that the desiccant can be filled into the cavity through the resulting gap.
- the cavity is opened so that even after the closure of the cavity, a gas connection between the cavity and a gap between two adjacent glass sheets is generated. This allows the desiccant to absorb the moisture stored in the space of the insulating glass pane.
- the opening of the cavity is preferably such that a first contact surface and a second contact surface of the spacer together define a longitudinal slot.
- the contact surfaces are substantially parallel to each other and in a plane parallel to a plane of the glass sheets.
- the contact surfaces can be even and thus form a dull shock.
- the contact surfaces are designed profiled. This results, for example, a tongue and groove-like connection of the two contact surfaces.
- the opening of the cavity is preferably along an existing slot in the spacer.
- Ren the slot is only generated when filling with desiccant.
- the opening, in particular the cutting, the cavity and the filling of the drying agent in a common step Preferably, a device with a combined separating and filling head is used for this purpose.
- the filling head with the separating tool placed in front thus preferably moves along the closed spacer and separates the cavity, so that the cavity can be provided with desiccant by a filling head.
- the filling head is guided through an already existing in the spacer parting line, in particular a slot formed by two contact surfaces. As a result, the cavity of the spacer must not be cut open.
- a further aspect of the invention relates to a device for applying a spacer to a glass pane and for introducing a drying agent into or onto a spacer by means of a filling head.
- the device comprises means for applying a flexible spacer along an edge region of a glass pane and means for applying a drying agent, in particular a filling head.
- the device is constructed in such a way that the spacer can be filled with desiccant during or after application to the glass pane.
- the devices for applying the spacer and for introducing the desiccant are integrated in a single machine, but alternative, a device of a plurality of individual components is conceivable.
- the device comprises a separating tool for opening a cavity to be filled with desiccant in the spacer.
- the cutting tool may comprise a blade with which a closed cavity of the spacer can be cut.
- the parting tool comprises two angularly arranged surfaces with which an already existing opening can be widened to the cavity, so that a filling head can insert the desiccant into the cavity.
- the separating tool is arranged in the direction of movement so directly in front of the filling head that the separation of the cavity and the filling with desiccant can be carried out in one working step.
- the direction of movement is defined as the direction in which the device moves relative to the spacer strip.
- the cutting tool can be moved along the fixed on a glass plate spacer. Preferably, however, the spacer is guided on the glass pane along the separating tool before application.
- the separating tool either remains in a fixed position or moves along the glass pane while simultaneously applying the spacer to the glass pane.
- Another aspect of the invention relates to a device for applying a spacer and for introducing a desiccant, which has a guide.
- this guide the spacer for filling with desiccant in the desired position is performed relative to the filling head or feasible.
- a separate guiding device is missing and the device is instead guided through the separating tool, which is preferably arranged in front of the filling head.
- the device can have an analysis device for measuring the degree of activity of the drying agent, it being possible in particular to measure the adsorption capacity of the drying agent by means of the analysis device. In this way, a quality assurance can be ensured.
- the analysis device can be connected to the feed channel via a bypass outlet.
- the degree of activity of the drying agent can be measured particularly easily and efficiently.
- the device may have a metering device for the drying agent, with which the filling of the spacer is adjustable.
- the metering device can have metering units which would each be assigned to a supply line.
