Description

The invention relates to a device for assembling insulating glass panes made of glass panels, which has a first horizontal conveyor with a conveyor track, a turning station, a second horizontal conveyor with two conveyor tracks and an assembly and pressing station, wherein the first horizontal conveyor the glass panels to be assembled into insulating glass panes to the rotating station, and the second horizontal conveyor conveys the glass sheets from the turning station to the assembling and pressing station, and a method for assembling insulating glass sheets from glass sheets, wherein the glass sheets are conveyed from a single-lane first horizontal conveyor to a turning station, in the turning station a first of two a glass sheet Pair of Educational Glass Panels rotated 180 ° and paired with a second glass sheet, and the pair of glass sheets thus formed is conveyed from a two-track second horizontal conveyor to an assembling and pressing station.

Such a device and such a method are known from DE 10 2012 000 464 A1 as well as the priority of this application WO 2013/104542 A1 known. In these documents, an apparatus and a method for assembling insulating glass panes of glass panels is described, which has a first horizontal conveyor with a conveyor track, a turning station, a second horizontal conveyor with two conveyor tracks and an assembly and pressing station, the first horizontal conveyor to zusammenzusetzenden the insulating glass panes Glass panels are conveyed to the turning station, the turning station pairs two glass panels and the second horizontal conveyor conveys the paired glass panels from the turning station to the assembly and pressing station. The turning station before or arranged downstream of a removal station is arranged, through which a glass panel conveyed by the single-lane first horizontal conveyor can be moved out of the transport path and brought into a parking lane. The rotating station in the conveying direction below a buffer station is arranged, in which two or more paired in the rotating station glass panel pairs can be introduced.

The known device is characterized by a short cycle time and thus a high production rate. By now provided that glass panels, which are not now to be assembled with the immediately preceding glass sheet to an insulating glass, removed in the removal station from the transport path of the first horizontal conveyor and parked in this station, the production reliability of the device according to the invention is significantly increased since It is no longer necessary, especially in the assembly of triple insulating glass, to comply with a complicated order of the glass panels in their task. Rather, the glass plates to be assembled in each case into an insulating glass pane can be placed directly one behind the other be, which is simplified in an advantageous manner, the production process.

In the aforementioned DE 10 2012 025 639 A1 Furthermore, a particularly suitable for use in the aforementioned device rotating station is described. This has a rotating frame with support walls which are inclined relative to the vertical. A device using this rotating station is characterized by a simple construction and a rapid operation, which leads to higher cycle times in the production of double or multiple insulating glass panes. The V-shaped configuration of the rotating frame with respect to the vertical inclined support walls here has the advantage that no additional means such as support rollers are required for supporting the glass panels; Rather, the inclination of the support walls relative to the vertical causes the glass panels to rest safely on the support walls by the action of gravity and therefore no fixation of the glass panels before, during or after rotation is required. As a result, performance increases over the known devices are possible, which may be two to four times.

A central component of the known device is thus the turning station used in her, which serves for pairing the glass panels. For this purpose, the turning station, after a first glass sheet has been introduced into this, performs a rotation through 180 °. Then the second glass sheet is placed in the turning station and the two glass sheets are combined to form a pair of glass sheets. It follows, however, that the length of the glass panels to be machined with the known device is limited by the length of the working space of the rotating station, since - as described above - the individual glass panels must be introduced into the turning station and rotated by it, thus pairing corresponding glass panels can be carried out.

For a variety of applications, however, it is desirable that in such a device insulating glass panes of different lengths can be produced, so that in a kind of "tandem operation" both "small" glass panels, that is, glass panels, which are introduced into the turning station and from her can be rotated, so even "large" glass panels, that is, glass panels whose length is greater than the available for receiving a glass panel in the turning station working space, can be processed. If the turning station is dimensioned in such a way that it can also process these "large" glass sheets, this leads to an increase in the cycle time and thus to a reduction in the production rate for "small" glass sheets, since one is also designed for "large" glass sheets Turning station construction-wise and dimensionally slower turning than one in which only "small" glass panels can be processed. The seemingly obvious way of simply enlarging the turning station to allow for tandem operation is therefore eliminated if a high production rate is to be achieved with "small" glass panels.

From the DE 44 37 998 A1 a device for the assembly of insulating glass panes is described from glass panels, which makes it possible to produce two or three glass panels existing insulating glass panes. In the former case of a double insulating glass pane, a first glass sheet is first conveyed on the first horizontal conveyor and enters the turning station. The glass sheet moves along a support wall of the horizontal conveyor, which is inclined by a few degrees, in particular by 6 °, to the vertical. The turning station has a mounted on one foot and according to the inclination of the support wall of the horizontal conveyor a few degrees inclined against the horizontal bogie, on which two parallel conveyor tracks are provided, each consisting of a horizontal row of synchronously driven rollers with matching diameter whose Rotary axes lie in a common plane which runs at a right angle to the support wall of the horizontal conveyor. To support the glass sheets has the rotating station of the known device support roller lines, namely one support roller line in Connection to the two rows of driven rollers, wherein between each two driven rollers is a support roller which projects slightly above the top of the driven rollers. One of the two conveyor tracks is still assigned a third support roller line which is substantially level with the first two support roller rows, but is between the two, in such a way that the support rollers of the support roller line in the spaces between the driven rollers in one of the two conveyor tracks intervention. The support roller rows thus assume the function of the support wall of the horizontal conveyor in the known rotary station. Since this support roller rows of the rotating station and the support wall of the horizontal conveyor are aligned, that are arranged at the same angle to the vertical, a glass panel can be easily transported from the first horizontal conveyor in the turning station. The bogie runs with multiple wheels on a circular path on top of the foot of the turning station, wherein the rotary drive z. B. via a pneumatically driven friction gear. The axis of rotation of the turning station is centered with respect to the length of the turning station and is close to the plane in which the axes of the support rollers of the central support roller line lie. Since the foot of the rotary station and thus the axis of rotation of the bogie is inclined at the same angle to the horizontal as the support wall of the horizontal conveyor to the vertical, the glass sheet in the starting position of the rotating device supporting support roller rows are again rotated at 180 ° to the rotation of 180 ° Supporting wall of the horizontal conveyor arranged to vertical, only offset by twice the radius of rotation relative to this position. As soon as the first glass sheet with its rear edge has run into the rotating frame of the turning station, it is stopped in a predetermined position and the rotating frame is rotated by 180 °. The glass sheet is then again arranged at the angle of the support wall of the horizontal conveyor to the vertical, but it is no longer in the plane of this support wall, but is removed from it by the aforementioned distance. It falls with its upper edge of the first support roller line against the adjacent second support roller line and is thus held by this support roller line quasi floating. After the rotary motion is completed by 180 ° and the rotating frame of the rotating station is fixed in this position, the second, with a spacer occupied glass panel in the second conveyor of the turning station promoted on the first horizontal conveyor until it is congruent with the first glass sheet. The second glass sheet and the first glass sheet are thus parallel and spaced from each other.

From this position, the two glass panels, as soon as the assembly and pressing device is ready and opened, are conveyed together by the second horizontal conveyor and simultaneously into its press nip. For this purpose, the two glass sheets are synchronously advanced by the two conveyor belts of the second horizontal conveyor until they have arrived with their front edge at the outlet end of the assembly and pressing station, where they are stopped in a predetermined position. Then, in a manner known per se, the filling of the insulating glass panes with a gas and their assembly to the finished insulating glass pane. In order to assemble a triple insulating glass pane consisting of three glass panels, it is provided that first of all a first and a second glass panel are assembled into a glass panel pair in the described manner. Meanwhile, the third glass panel is fed into the turning station and rotated there by 180 °. Once the first and second glass sheets are assembled, the blank formed therefrom is fed out of the assembly and pressing station, stopped on a subsequent further horizontal conveyor, and the first glass sheet is there provided with a further spacer. Meanwhile, the third glass sheet on the second conveying path is fed to the movable pressing plate of the assembling and pressing station. Thereafter, the occupied with the second spacer blank is returned to the assembly and pressing device and there positioned congruent with the third glass panel, assembled with this and optionally. Provided with a heavy gas filling. Thereafter, the thus assembled triple insulating glass sheet is pressed and conveyed away.

This known device has the disadvantage that it allows only very slow cycle times, since the supply of the second glass sheet of a pair of glass sheets to be assembled into a two-pane insulating glass pane can only then take place after the first glass sheet has been rotated by 180 ° from the turning station as described was rotated and fixed there in its "floating" position. For this purpose, as also already described, it is necessary for the supporting line rollers supporting the glass panel to be positioned before rotation of the glass panel can take place. The requirement to fix the glass sheet in its rotated position, further brings with it the disadvantage that with the known device only rectangular glass sheets with at least the same dimension in height and therefore no model formats can be processed. In addition, it is necessary that the glass panels to be assembled into an insulating glass pane are placed in a defined order.

This known device further has the disadvantage that it has only a very low clock rate and thus a low production capacity in the production of triple-insulating glass panes. In order to produce a triple insulating glass pane, after assembly, the resulting blank from the assembly and pressing station must be moved out to secure a further spacer to one of the two glass plates forming the blank. Thereafter, the blank together with the spacer attached to it must be conveyed back into the assembly and pressing station before it can be assembled with the third glass panel to a triple-glazed pane, which increases the cycle time again considerably. The function of the known turning station contributes primarily to rotate the coated side of functional glasses by 180 ° inwards before assembly without this coated side is touched. For this purpose, significantly longer cycle times are accepted. This disadvantageously reduces the production capacity of the known device.

A development of the known from the aforementioned document device is in the EP 0 857 849 A2 disclosed. From this document, a device for assembling insulating glass panes of glass panels is known, which has a horizontal conveyor on which the insulating glass panes or their blanks stand upright. Above the horizontal conveyor, a support device is arranged, on which lean the standing on the horizontal conveyor insulating glass panes or their blanks. For the assembly of the insulating glass panes it is provided that a supported on its first surface first glass sheet is conveyed to a certain position on a first path of the horizontal conveyor in the turning station. Then, a second glass sheet is conveyed to a certain second position on the first path of the horizontal conveyor in the turning station. Then, the first and the second glass sheet in the turning station are displaced by a second web of the horizontal conveyor parallel to the first web. This shifting of the first and the second glass sheet is effected by the fact that the receiving them rotating frame of the rotating station is rotated by 180 ° about an axis parallel to the glass panels by 180 °, so that the first located on the first conveyor track first and second glass panel after this Turn on the second conveyor of the rotary conveyor passing through the horizontal conveyor. By this measure it is achieved that then the first conveyor track is free for the transport of the third and the fourth glass panel. The third and fourth sheets of glass are conveyed until the two sheets of glass have arrived on the first web of the turning station, with either the first and second or third and fourth sheets carrying a frame-shaped spacer on their unsupported surface. The two glass panel pairs, ie the first and the third and the second and the fourth glass panel are positioned parallel and congruent at a distance from each other and simultaneously transferred to the assembly and pressing device. This known device has - since it uses the same turning station as that from the DE 44 37 998 A1 known device - also their disadvantages. In particular, it has the disadvantage that it allows only extremely expensive to produce triple insulating glass panes.

The DE 10 2004 009 858 B4 describes a method and apparatus for positioning mutually opposite glass sheets in a vertical assembly and press apparatus which is part of the production line for insulating glass sheets. In this production line, a first glass sheet and a second glass sheet provided with a spacer are supported on a horizontal conveyor and, leaning against an inclined first support, are fed to the assembling and pressing apparatus of the production line. This has an arrangement of two pressing plates, which are convertible from a first position in which they are inclined in the opposite direction, in a second position in which they are parallel to each other. The first glass sheet leaning against the first supporting means is conveyed on a first portion of the horizontal conveyor to a predetermined first position in which it is stopped and which is in front of the assembling and pressing apparatus. Then, this first glass sheet is transversely to the conveying direction of the horizontal conveyor in a position opposite the first layer in which it is leaning on the horizontal conveyor standing against a second support means, which is inclined in the opposite direction than the first support means transferred. The leaning against the first support means second glass sheet is conveyed to the aforementioned first position. This process is followed by concurrent feeding of the first and second glass sheets, the glass sheets resting against their respective support means on a second section of the horizontal conveyor which is drivable separately from its first section. By repeating the aforementioned steps for glass panels, which are intended for assembly of at least one further insulating glass pane, at least once, a second pair of glass sheets is formed. In this case, the first pair of glass sheets already standing on the second section of the horizontal conveyor is advanced by more than the length of the or each pair of glass sheets that follow each other. The thus formed two glass panel pairs are then introduced by a concurrent Weiterfördern on the second portion of the horizontal conveyor in the open assembly and pressing device having a third portion of the horizontal conveyor, which is separately from the second section of the horizontal conveyor eintragbar introduced, and the insulating glass pane is assembled.

It is an object of the present invention, a device and a method of the type mentioned in such a way that in a simple manner an efficient production of insulating glass panes of different lengths is possible.

To achieve the above object, the device according to the invention proposes that the rotating station in the conveying direction of the glass panels below a rotatable buffer station is arranged.

According to a further solution to this problem, it is proposed according to the invention that the turning station has a rotating device and at least one extension device which can be coupled to the rotating device and is rotatable therewith in the coupled state.

The inventive method provides that for the assembly of further glass sheets, these glass sheets are conveyed through the rotating station to a rotatable buffer station, that in the rotatable buffer station a first of two glass panel pair forming glass panels rotated by 180 ° and subsequently with the in the rotatable buffer station is introduced paired second glass panel.

The measures according to the invention have the advantage that in this way advantageously in a single device and with a single method in a kind of "tandem operation" in a first operating mode the production is "smaller" and in a second operating mode the production is "large" insulating glass panes From two or more glass panels is made possible, without losing the advantages that are given in the aforementioned device and the aforementioned method in the production of "small" insulating glass, in particular a short cycle time and a high production rate to lose. By the invention it is provided that the device according to the invention and the inventive method are designed such that in the processing of "small" glass panels in the first mode of operation, the device works the same way and the process is carried out exactly as in the known device and the known method is the case, and only for the processing of "large" glass panels in the second mode, the buffer station is rotated or the rotary station is extended by the coupling of at least one extension device, remain the advantageous properties of the known device and the known method in the processing of " small "glass panels fully preserved. The device according to the invention is operated only in its second operating mode, in which a rotational movement of the buffer station or an extension of the rotating station takes place, if this is necessary for the processing of correspondingly large glass sheets: By these measures, an apparatus is advantageously created, which is characterized by a simplified structure and a faster operation, which leads to higher cycle times in the production of double or multiple insulating glass panes.

An advantageous development of the invention provides that the rotatable buffer station has a rotating frame with support walls which are inclined relative to the vertical. Such a measure has the advantage that the resulting V-shaped configuration of the rotating frame of the rotatable buffer station with respect to the vertical inclined support walls requires no further means for supporting the "large" glass sheet during its processing in the inventively provided rotatable buffer station. There are thus achieved by this embodiment, the same advantages as they are given, if according to a further advantageous embodiment of the invention also the turning station has a rotating frame with support walls which are inclined relative to the vertical. The V-shaped configuration of the rotating frame of the rotatable buffer station with respect to the vertical inclined support walls has the advantage that for supporting the "large" glass panels, especially in their rotated position by 180 °, no additional means such as support rollers, which - as described above - must be positioned consuming, are required. Rather, the inclination of the support walls relative to the vertical causes the glass panels safely rest on the support walls by the action of gravity. Since no fixing of the glass panels before, during and after rotation is required, the buffer station according to the invention operates quickly: Immediately after the first glass panel enters the buffer station, the "large" glass panel leaning on the first support panel can be rotated. After completion of this turning operation, it is then possible to immediately introduce the second "large" glass panel in the buffer station according to the invention, wherein it rests against the second support wall. It is thus possible even with "large" glass panels performance increases over the known device, which may be two to four times.

Preferably, the rotary station upstream of the rotating station is also provided with V-shaped arranged support walls. This thus also rotates faster than the known from the cited document rotary station, which leads to higher cycle times of the buffer station according to the invention and the V-shaped rotating station using apparatus for the production of insulating glass panes. The two such paired glass sheets can then be transported immediately to the further processing station of the apparatus adjacent to the buffer station and the V-shaped turning station.

The V-shaped design of the buffer station and the V-shaped rotating station also have the advantage that not only rectangular glass panels can be processed with it, but also model formats, since for positioning the "large" and the "small" glass panels no further Facilities more required are. This is particularly advantageous for glass panels with a sensitive coating, since this coating is not exposed to mechanical loading during the entire manufacturing process.

A further advantageous development of the invention provides that at least one extension device, which can be coupled to a rotating device of the rotating station according to the invention, has a rotating frame with support walls inclined towards the vertical. The advantages of the V-shaped design of the corresponding rotary frame described above for the rotatable buffer station and the rotary station are consequently also realized in the rotary station according to the invention consisting of the central rotary device and at least one extension device.

A further advantageous development of the invention provides that the rotatable buffer station has two conveyor tracks which can be driven independently of one another, the first conveyor track and, in the rotated state of the rotatable buffer station, the second conveyor track being aligned with a first conveyor track of the rotary station.

A further advantageous development of the invention provides that the turning station has two conveyor tracks which can be driven independently of each other, and that the first conveyor track and in the rotated state of the rotary station the second conveyor track are aligned with the first conveyor track of the first horizontal conveyor.

A further advantageous development of the invention provides that the swivel station upstream or downstream of a swap station is arranged, through which a glass panel conveyed by the single-track first horizontal conveyor can be moved out of the transport path and brought into a parking lane. By these measures is advantageously a device for assembly created by insulating glass, which is characterized by a short cycle time and thus a high production rate. By now provided that glass panels, which are now not to be assembled with the immediately preceding glass panels to an insulating glass, removed in the invention provided for retrieval from the transport path of the first horizontal conveyor and parked in this station, the production reliability of the device and the invention significantly increased process according to the invention, since it is no longer necessary, especially in the assembly of triple insulating glass, to comply with a complicated order of the glass sheets in their task. Rather, the glass sheets to be assembled in each case into an insulating glass pane can be placed directly one behind the other, as a result of which the production process is simplified in an advantageous manner. The measures according to the invention now also make it possible to assemble several glass sheets into a corresponding number of insulating glass panes in the assembly and pressing station. The device according to the invention and the method according to the invention are also suitable in particular for model glass panes. Another advantage is that with the described device and the described method, in particular functional glass panes, which have a coating on one side, can be assembled together to form corresponding insulating glass panes.

A further advantageous embodiment of the invention provides that the removal station is arranged in front of the turning station. According to the invention, it is thus provided that the removal station is arranged between the single-lane first horizontal conveyor and the two-lane rotary station. This ensures that the retrieval station can be easily formed because the glass panel to be parked in each case only needs to be removed from a single conveyor track.

A further advantageous embodiment of the invention provides that the removal station is arranged after the turning station. Such a measure has the advantage that in this way a short cycle time is achieved in the turning station, since the aging takes place only after the pairing of the glass panels in the turning station and the removal of the corresponding glass panel can advantageously be done only when the required number of paired glass panels, which are assembled in the assembly and pressing station to a glass panel pair, in the Turning station were paired.

A further advantageous development of the invention provides that the glass panel to be outsourced is moved by the turning station into the removal station. Such a measure has the advantage that the removal station can be arranged outside the actual transport path of the glass panels and the auszulagernde glass sheet can be performed by a rotational movement of the rotating station and then conveying the auszulagernden glass sheet from the turning station in the removal station. Such a measure has the advantage that in this way already existing devices can be retrofitted in a simple manner.

A further advantageous development of the invention provides that the rotatable buffer station is assigned a lock station and / or the rotary station is assigned a further lock station. This measure according to the invention has the advantage that this makes it possible in a simple manner to introduce or remove glass sheets from the device.

Further advantageous developments of the invention are the subject of the dependent claims.

In the Figures 1a-1d and 2a-2d Now, a generally designated 1 embodiment of an apparatus for assembling insulating glass panes is shown, the individual stations are substantially known and therefore not described in detail. The device 10 has a single-track first horizontal conveyor 20, which has a conveyor track 21. The conveyor track 21 of the first horizontal conveyor 20 may be formed in a known manner by a row of driven rollers 22. But it is also possible to use a circulating conveyor belt or similar device for this purpose. The first horizontal conveyor 20 has a support means 23 which, in the embodiment described here, is inclined, preferably inclined at 6 ° to the vertical, and on which the glass sheets are supported during their transport movement. Also, such a horizontal conveyor 20 is known and therefore need not be described in detail. He passes through a washing station 30 in which to be assembled to the insulating glass pane glass panels are cleaned. The glass panels set up in a receiving station (not shown) and cleaned in the washing station 30 are brought by the first horizontal conveyor 20 - past a visit and frame setting station 32 - to an outfeed device 40, the structure and function of which will be described below. In the conveying direction below, a rotating station 50 is arranged, the two conveyor tracks 51 a and 51 b (see FIG. 1b ), wherein the conveyor track 21 of the first horizontal conveyor 20 - corresponding to the rotational position of the rotary station 50 - either with the first conveyor track 51 a or 51 b aligned with the second conveyor track, so that the glass panels from the first horizontal conveyor 20 in each of its conveyor track 21st aligned conveyor tracks 51 a or 51 b of the rotating station 50 can be passed. In the conveying direction connects to the turning station 50, a two-lane second horizontal conveyor 60, the two conveyor tracks 61 a and 61 b (see FIG. 2b ) having. These are aligned with the conveyor tracks 51 a, 51 b of the rotating station 50, so that glass panels located on these conveyor tracks 51 a, 51 b can be transferred to the conveyor tracks 61 a, 61 b of the second horizontal conveyor 60.

The rotating station 50 driven by a drive means 50 "has a length which allows glass panels 1A, 2A to be inserted therein, these glass panels 1A, 2A having a first length l _1. A rotating frame 52 of the rotating station 50 is substantially orthogonal Rotatable to the conveying direction of the glass panels axis, so that after a 180 ° rotation of the in FIG. 1 front end 52a, which faces a buffer station 70, in the rotated state then the first horizontal conveyor 20 and its second end 52b of the buffer station 70 faces. The rotary frame 52 rotatably driven by a drive device 50 'is essentially formed by two support walls 53a and 53b inclined relative to the vertical, preferably at an angle of 6 °, having a plurality of support rollers (not shown) along which the glass sheets are movable , The supported by the first support wall 53a glass plate sets with its lower edge in this case on rollers of the first conveyor track 51 a and on the second support wall 52b supporting glass plate sets on rollers of the second conveyor track 51 b. The rotary station 50 is thus formed in two lanes and the rollers of the first conveyor track 51 a and the rollers of the second conveyor track 51 b are independently drivable, so that - as described below - on each of the two tracks of the rotary station 50 one or more located on a track Glass panels can be moved independently of the located on the other track glass panels. For further details regarding the structure and operation of the rotary station 50 is on the DE 10 2012 000 464 A1 Reference is made, the disclosure of which is the subject of the present application by this reference.

The second horizontal conveyor 60 has two preferably independently drivable sections 60a and 60b. The first portion 60a passes through the buffer station 70 and the second portion 60b passes through an assembly and press station 80. The construction of a preferred embodiment of the buffer station 70 and the assembly and press station 80 are in the international patent application WO 2005/080739 to which reference is made to avoid repetition and their disclosure by this reference to the subject this application is made. In the following, therefore, the special design, the buffer station 70 and the assembly and pressing station 80 will be explained only to the extent that is expedient or necessary for the understanding of this application.

In contrast to the known from the aforementioned document buffer station, the buffer station 70 of the device 1 described here is designed to be rotatable, so that after a rotation of 180 ° in her FIG. 1 front end 70a, which is associated with the rotating station 50, in the rotated state then the assembly and pressing station 80 and its rear end 70b of the rotating station 50 faces. The driven by a drive device 70c buffer station 70 has a rotatably driven by the drive means 70c rotary frame 72, which - as well as the rotating frame 52 of the rotating station - against the vertical, preferably at an angle of 6 °, inclined support walls 73a and 73b having a Has a plurality of support rollers (not shown), along which the glass sheets are movable. The rotatable buffer station 70 in this case has a length which allows at least one glass panel 3A, which has a length l ₂ with l ₂ > l _{1 to introduce} and rotate. The supported by the first support wall 73a glass plate sets with its lower edge thereby on rollers of a first conveyor track 61a of the first portion 60a of the second horizontal conveyor 60 and on the second support wall 73b supporting glass plate sets on rollers of a second conveyor belt 61 b of the first portion 60a of second horizontal conveyor. The buffer station 70 is thus - like the turning station 50 - formed in two lanes and the rollers of the first conveyor track 61 a and the second conveyor track 61 b of the first portion 60 a and the second portion 60 b of the second horizontal conveyor 60 are preferably independently driven, so that for each of the two tracks of the buffer station 70 and / or the assembly and pressing station 80 can be moved one or more on one track glass panels independently of the located on the other track glass panels.

The basic operation of the device is based on the Figures 1a-1d explained. With the device 1, "small" glass sheets 1A, 1B and 2A, 2B are respectively assembled into an insulating glass sheet 1AB and 2AB, that is, glass sheets 1A, 1B, 2A, 2B inserted into and rotated by the turning station 50 can be, the rotatable buffer station 70 of the given first mode of operation of the device 1 is operated in a "passive mode", that is, it is in its normal position and performs no rotational movement during the processing of the "small" glass panels. The operation of the device 1 described is thus the same as in the above-mentioned DE 10 2012 000 464 A1 as well as the WO 2013/104542 A1 described device.

For the sake of completeness, this mode of operation but briefly based on the Figures 1a-1d A first glass panel pair 1AB composed of two glass sheets 1A and 1B is already present in the buffer station 70; a first glass sheet 2A is inserted in the turning station 50.

How out Figure 1 b can be seen, then the rotating station 50 is rotated by 180 ° until it is in their in Figure 1 c arrived position shown. Then, by means of the first horizontal conveyor 20, a second glass sheet 2B is introduced into the turning station and paired to a glass sheet pair 2AB.

Like from the Figure 1d can be seen, the second pair of glass panel 2AB is then introduced into the buffer station 70, wherein during the introduction process of this second glass panel pair 2AB the already located in the buffer station 70 first glass panel pair 1AB is moved further, so that then the two Glass panel pair 1AB and 2AB are located in the buffer station 70. These are then introduced in a manner known per se and therefore not described in more detail from the second horizontal conveyor 60 in the assembly and pressing station 80 and assembled there in a likewise known manner to form a double insulating glass pane.

Now with the device 1 "large" glass sheets 3A, 3B, ie glass sheets 3A, 3B, whose length l _{2 is} greater than the length l _{1 of} the glass sheets 1A, 1B, 2A, 2B, which can be rotated by the rotating station 50 , so will from the Figures 2c-2d The turning station 50 and the rotatable buffer station 70 are shown in the representation of FIG. 2a in their basic position, the support walls 53a and 73a and 53b and 73b of the rotating frame 52 and 72 of the rotating station 50 and the rotatable buffer station 70 are thus aligned with each other, so that a first "large" glass panel 3A - FIG. 2a seen - can be introduced through the rotating station 50 in the buffer station 70.

Is this glass panel 3A now - as previously a "small" glass panel 1A or 2A rotary station 50 was introduced into the rotatable buffer station 70 is introduced, so is on the first support wall 73a of the rotary frame 70, it will - as out FIG. 2b visible - the rotatable buffer station 70 rotated by 180 °. Thus, the in Figure 2c shown position. It can be seen that the first glass panel 3A now faces the observer. Then, the second glass sheet 3B is inserted through the rotary station 50, which is still in its home position, into the rotatable buffer station 70 and then rests on the second support wall 73b. As a result, the "large" glass sheets 3A, 3B are then paired to form a glass sheet pair 3AB, just as the "small" glass sheets 1A, 1B and 2A, 2B in the rotating station 50 are paired with glass sheet pairs 1AB and 2AB, respectively were. The glass panel pair 3AB is then introduced into this station in a manner known per se by the first section 60a of the second horizontal conveyor 60 and its second section 60b passing through the assembly and pressing station 80 and converted in a known manner into a double section. Insulated glass pane assembled.

As can be seen from the above description, in assembling the "small" glass panels 1A, 1B and 2A, 2B, the rotatable buffer station 70 serves to glass panel pairs 1AB and 2AB, respectively, for buffering these glass panel pairs before they be introduced together into the assembly and pressing station 80. The buffer station 70 therefore preferably has a length which is dimensioned such that not only "large" glass sheets 3A, 3B having the length l ₂ can be processed therein, but also at least two "small" glass sheets in it Pairs 1AB, 2AB, which have a length l ₁ , can be accommodated. Of course, it is also possible to form the buffer station 70 in such a way that more than two glass panel pairs 1AB, 2AB, each having the length h, can be accommodated in it. In the case shown here, the buffer station 70 has a length which is the inclusion of three glass panel pairs 1AB, 2AB, each having a length l ₁ , as well as "large" glass panels 3A, 3B with a length to l ₂ = 3 l ₁ allowed. It will be apparent to those skilled in the art from the foregoing description that the sizing of the length of the rotary buffer 70 shown in the Figures and described above is only exemplary. It is preferred that the rotatable buffer memory 70 for receiving two "small" glass panel pairs 1AB, 2AB each having a length l ₁ and a "large" glass panel pair 3AB with a length l ₂ = 2 l _{1 is} formed.

In the Figures 3a-3d and 4a-4d Now, a second embodiment of a device 1 'is shown, wherein corresponding stations and components are provided with the same reference numerals and will not be described in more detail.

The device 1 'of the second embodiment has a buffer station 70', which is now - in contrast to the rotatable buffer station 70 of the first embodiment - not necessarily rotatable, but is stationary in the embodiment described here. The skilled person will be apparent from the following description that this buffer station 70 ', which is arranged between a turning station 50 of the first embodiment corresponding turning station 50' and the assembly and pressing station 80, although advantageous for an efficient production process, but not mandatory and therefore can also be omitted.

The essential difference between the two embodiments is that, in the device 1 'of the second embodiment, the rotating station 50' takes over the function of the rotatable buffer station 70 of the first embodiment, that is, it is designed so that it both the smaller "Glass sheets 1A, 1B, 2A, 2B, which have the length l ₁ , as well as those" large "glass sheets 3A, 3B having a length l ₂ > l ₁ allowed. For this purpose, it is provided that the rotating station 50 'has a rotating device 50a', which is formed like the rotating station 50 of the first embodiment and is therefore not described in detail. The essential constructive difference between the turning station 50 'of the second embodiment and the turning station 50 of the first embodiment is now that the turning station 50' at least one, in the embodiment described here has two connectable extension devices 50b 'and 50c', which is connected to the rotator 50a ' can be coupled and thus the rotating device 50a 'extend so far that with her also "large" glass panels 3A, 3B are rotatable. In the exemplary embodiment shown here, the extension devices 50b 'and 50c' are each arranged on one side of the rotary device 50a '. In principle, it is also possible to provide only one extension device on one side of the rotary device 50a ', which then has to be dimensioned correspondingly long. However, the solution is not preferred since this results in an asymmetrical structure of the rotating station 50 '.

Each of the two extension devices 50b 'and 50c' preferably has in each case a frame 52 'with each inclined against the vertical support walls 53a' and 53b ', which are aligned with the support walls 53a, 53b of the rotating frame 52 of the rotator 50a'.

The operation of the device 1 'of the second embodiment is now as follows: If' small 'glass panels are to be processed with the device 1', then the two extension devices 50b 'and 50c' are decoupled from the rotator 50a ', as shown in FIG FIG. 3a is shown. In this first mode Thus, only the rotating device 50a 'of the rotating station 50' rotates in the device 1 '. This corresponds to the function of the rotating station 50 of the first embodiment. A first glass sheet 1A is - as described above - introduced through the first extension means 50b 'in the rotator 50a', this is then rotated by 180 °. Then, a second glass sheet 1B - again inserted through the first extension means 50b 'decoupled from the rotating means 50a' into the rotating means 50a 'and in this paired to a glass sheet pair 1AB. This will then - as from the Figure 3c seen - brought by the also of the rotating station 50a 'decoupled second extension device 50c through to the buffer station 70' or - if this, as stated above, is not provided - directly into the assembly and pressing station 80 introduced (see 3d figure ).

In order now in the turning station 50 'and "large" glass panels 3A, 3B to rotate, is now - as out FIG. 4a can be seen - provided that the extension devices 50b 'and 50c' are coupled to the rotator 50a ', so that these two extension devices 50b' and 50c 'together with the rotator 50a' can be rotated. A first glass sheet 3A is then inserted into the rotating station 50a thus extended (in the same way as the "small" glass sheets 1A and 2A are introduced into the turning station 50) ( FIG. 4b ). The turning station 50 'will then - as out Figure 4c visible - rotated by 180 °. Then, the second glass sheet 3B is inserted into the rotating station 50 ', whereby the glass sheet pair 3AB is formed. This will then - as in FIG. 4d shown - introduced by the buffer station 70 'or directly into the assembly and pressing station 80.

The devices 1 and 1 'described thus allow in an advantageous manner by the above-described two modes of operation a "tandem mode" in which a single production line both "small" glass sheets 1A-2B, that is, glass sheets of length l _1, in the turning station 50 and in the rotator 50 'can be introduced and rotated in this, as well as "large" Glass panels 3A, 3B, that is, glass panels of length l ₂ > l ₁ , which no longer fit into the rotating station 50 and in the rotator 50 'to process, without thereby in particular in the processing of these aforementioned "small" glass panels no opposite the one from the DE 10 2012 000 464 A1 or the WO 2013/104542 A1 known device, a reduced efficiency, in particular a higher cycle time occurs.

Further details of the devices 1 and 1 'are now described below: Before the glass sheets 1A, 2B, 3A, 3B are transported by the first horizontal conveyor 20 from the washing station 30 to the rotary station 50, they pass through the unloading station 40. Their task is a glass panel located on the conveyor track 21 of the first horizontal conveyor 20 to remove from this track, so that by the first horizontal conveyor 20, the further glass panel placed behind this glass panel can be promoted from the washing station 30 to the rotating station 50. The removal station 40 thus displaces a glass panel in it from the first track formed by the conveyor belt 21 of the first horizontal conveyor 20 to a second track in which the glass panel thus displaced can be "parked". For further details of this removal station 40 is in turn to the aforementioned patent applications of DE 10 2012 000 464 A1 and the WO 2013/104542 A1 directed. The retrieval station 40 is in turn advantageous if the described devices 1, 1 'not only - as described above - double insulating glass panes, but in particular triple insulating glass panes to be produced.

The above description has assumed that double insulating glass panes are produced from "small" glass sheets 1A, 1B and 2A, 2B and "large" glass sheets 3A, 3B, of course. In the case of the "small" glass panels 1A, 1B and 2A, 2B, which are to be assembled with further glass panels 1C and 2C into triple insulating glass panes, this is done in the first operating mode of the apparatuses 1b or 1 ', in the the buffer station 70 or 70 'is operated in its "passive mode" at the buffer station 70 as in FIG DE 10 2012 000 464 A1 as well as the WO 2013/104542 A1 described and in the FIG. 5 After each two glass sheets 1A, 1B and 2A, 2B were paired in the rotating station 50 and placed in the buffer station 70 (lines 1 to 7 of FIG. 5 ), these glass sheets 1A, 1B and 2A, 2B are transported from the second horizontal conveyor 60 to the assembling and pressing station 80 (line 8). After assembling these glass sheets 1A, 1B and 2A, 2B to the two glass sheet pairs 1AB and 2AB, that is, to a first member of the triple insulating glass sheet to be produced therefrom, the thus formed members become on the second conveying sheet 61b of the second horizontal conveyor 60 associated side of the assembly and pressing station 80 stored. Then, third glass sheets 1C and 2C are moved through the rotating station 50 and the rotatable buffer station 70 on the first conveying track 61a of the second horizontal conveyor 60 to the assembling and pressing station 80, opposite to the glass sheet pairs 1AB, 2AB already located and assembled therein ( Line 9) and then assembled by a corresponding operation of the assembly and pressing station 80 into "small" triple insulating glass panes 1ABC, 2ABC (line 10). For further details of this assembly is based on the aforementioned publications DE 10 2012 000 464 A1 respectively. WO 2013/104542 A1 directed.

In order to assemble also "large" glass panels 3A, 3B together with another "large" glass panel 3C to form a triple insulating glass panel, as in the flow chart of FIG FIG. 6 First, the two "large" glass sheets 3A and 3B are paired as described above in the rotatable buffer station 70 of the apparatus 1 (lines 1 to 3 of FIG FIG. 6 ). The two glass sheets 3A and 3B are then conveyed from the two conveying tracks 61a and 61b of the second horizontal conveyor 60 to the assembling and pressing station 80, assembled there into a glass sheet pair 3AB, and assembled on the second conveying track 61b side - And pressing station 80 filed. Then, another "large" glass sheet 3C is formed by itself in this second mode in its "passive mode" located rotary station 50 and the rotatable buffer station 70 of the device 1 therethrough on the first track 61a of the second horizontal conveyor 60 to the assembly and pressing station 80 moves and there with the already located in this station glass panel pair 3AB a "large" triple insulating glass pane 3ABC assembled (lines 4 to 7).

The device described is not only suitable for the efficient production of insulating glass panes of different lengths, but also advantageously makes it possible to simplify their manufacture, according to a method described in US Pat FIGS. 7 to 10 illustrated third embodiment, a input and / or rejection of individual glass panels is feasible. The third embodiment corresponds to its basic structure according to the first of the two embodiments described above, so that corresponding components provided with the same reference numerals and will not be described in detail.

It is envisaged that the rotatable buffer station 70 of the device 1, an input and / or Ausschleusestation, hereinafter briefly lock station 90, is assigned. This lock station 90 serves to remove individual glass sheets 1A-3B from the transport path of the glass sheets, if this is required or required for manufacturing reasons. In particular, defective glass sheets 1A-3B or glass sheets, which for other reasons are to be removed from the transport path to the assembly and pressing station 80, can thereby be removed. The third embodiment of the described device 1 thus allows an individual discharge of a glass sheet 1A-3B located in the transport path, which will be described in detail below. As a result, the production process is accelerated in an advantageous manner, since it was no longer - as in known devices - was required to "drive the device 1" by the glass plates in their succession before the auszuschleusenden glass panels to the assembly and Press station 80 had to be conveyed and assembled there before the defective or For other reasons, glass plate to be removed from the transport path could be removed from the device 1 by being moved through the assembly and pressing station 80.

As will also be apparent from the following description, it is preferably also possible for individual glass sheets 1A-3B to be introduced into the buffer station 70 by the transfer station 90. Such a measure is particularly advantageous if z. B. special glass panels with a special, especially sensitive coating to be processed, which should not go through the entire transport path between the feeding station 20 and the buffer station 70 due to their sensitivity or other reasons.

In order to be able to accomplish the discharging and / or preferably also an introduction of a glass panel from or into the transport path of the glass panels, it is provided that - as best of FIG. 9 it can be seen - the lock station 90 is arranged at the turning circle K of the rotatable buffer station 70 such that in a discharge position of the buffer station 70 located in this, auszuschleusende glass panel can be transferred from the buffer station 70 in the lock station 90. For this purpose, the buffer station 70 of hers in the FIGS. 7 and 8th shown basic position in which the buffer station 70 is in the transport path of the glass sheets 1A-3B - as described above - in an in FIG. 9 moved lock position shown. In this, the rotatable buffer station 70 is oriented such that one or more glass sheets 1A-3B can be transferred to the lock station 90.

In the case shown here, the lock station 90 - as in FIG. 7 illustrated - a horizontal conveyor 91 with a conveyor track 91 ', which - according to the conveyor track 21 of the first horizontal conveyor 20 - is formed by a row of driven rollers 92. However, it is also possible here to use a circulating conveyor belt or a similar device for forming the conveyor track 91 '. The lock station 90 has a support 93 which, in the case shown here, has a support wall 93a which has a plurality of support rollers (not shown) along which the glass sheets are movable. The supported by the support wall 93a glass panel sets with its lower edge on the rollers 92 of the conveyor track 91 'of the horizontal conveyor 91. The formation of the support wall 93a corresponds to that of the support wall 73a of the buffer station 70 and, like this, is inclined with respect to the vertical, so that in the lock position of the buffer station 70 the support wall 93a is aligned with the corresponding support wall 73a or 73b of the buffer station 70. The glass panel to be ejected can thus be easily moved from the corresponding support wall 73a or 73b to the support wall 93a of the lock station 90.

In the described embodiment, the lock station 90 consists of two units 90a and 90b, which are formed as described above. This is not mandatory. Rather, it is also possible that the support wall 93a and the conveyor track 91 'are integrally formed.

It is assumed above that the support device 93 has a support wall 93a with support rollers. This is not mandatory. It is also possible to provide, instead of the support rollers, an air cushion or similar means which causes the glass panels 1A-3B to be supported as they move through the conveyor track 91 '.

Should now a glass panel, z. Example, the glass sheet 3 A, which is located on the first conveying path 61 a of the first portion 60 a of the second horizontal conveyor 60 and is supported by the first support wall 73 b of the rotary buffer station 70 are brought into the lock station 90, the rotatable buffer station 70 so far rotated until the first support wall 73a with the support wall 93a of the lock station 90 is aligned. The first conveyor track 61 a of the rotatable buffer station 70 and the conveyor track 91 'of the horizontal conveyor 91 of the lock station 90 then move this glass panel 3A from the rotatable buffer station 70 into the lock station 90, whereby it is discharged from the transport path of the device 1.

Since, as described below, the glass sheets 1A-3B are already paired with the rotatable buffer station 70, it is necessary or expedient to remove another glass sheet from the rotatable buffer station 70 and thus from the apparatus 1 for a variety of applications. Should now z. B. a correlated with the glass sheet 3 A glass panel 3 B, which is located on the second conveyor track 61 b of the first portion 60 a of the second horizontal conveyor 60 and is supported by the second support wall 73 b of the rotatable buffer station are discharged from the device 1, the rotatable buffer station 70 is rotated such that the second support wall 73b with the support wall 93a of the lock station 90 is aligned. The discharging of this second glass sheet 3 B is then the same as the previously described discharging the first glass sheet 3 A.

In the above description, it is assumed that the lock station 90 is formed in one lane, ie, that the horizontal conveyor 91 has only a single conveyor track 91 a. From the above-described discharge of the second glass sheet 3B, it is quite expedient that two or more glass sheets located on different conveyor tracks 61a and 61b are discharged simultaneously or in succession. For this purpose, it is expedient that the lock station 90 is formed two lanes. It then has - not shown in the figures - a further conveyor track and a further support means, which are formed according to the conveyor track 91a and the support means 93. The support walls 93a are thus again arranged in a V-shape. In the lock position of the rotatable buffer station 70 thus aligns the first support wall 73a with the support wall 93a and the second support wall 73b with the other support wall. This allows two glass sheets 3A, 3B, which are each located on one of the two conveyor tracks 61a and 61b of the buffer station 70, to be transferred into the lock station 90 at the same time.

In the exemplary embodiment described here, it is assumed that large glass sheets 3A, 3B are to be discharged through the buffer station 70 and the lock station 90. As a result, the lock station 90 has a length which corresponds to the length of the buffer station 70, so that "large" glass panels 3A, 3B can also be accommodated in the lock station 90. Of course, if only "small" glass sheets 1A-2B are to be discharged for certain applications, then it is not necessary for the lock station 90 to have the length described above. In this case, it is also sufficient that the lock station 90 has only one of the two units 90a and 90b forming it.

For introducing a glass sheet 1A-3B into the buffer station 70, the procedure is as follows: The glass sheet to be inserted is fed into the lock station 90. Then, the buffer station 70 is moved to its lock position, so that in turn the rotatable buffer station 70 and the lock station 90 are aligned. Then, from the conveyor track 91 'of the horizontal conveyor 91 of the lock station 90, the glass panel placed in it is introduced into the rotatable buffer station 70.

Preferably, it can also be provided that the device 1 has a further lock station 100, which is assigned to the rotary station 50 and arranged at its turning circle K '. This then serves for the discharge of glass sheets 1A-2B from the turning station 50. The further lock station 100 has a horizontal conveyor 101, which has a conveyor track 101 'with rollers 102. It is a support means 103 provided with a support wall 103a, which also has not shown support rollers here. The support wall 103a of the support device 103 is in turn inclined to the vertical in such a way that it is aligned with the cooperating support wall 53a or 53b of the rotating station 50. The further lock station 100 is thus designed in accordance with the lock station 90, so that a further description of the same is not required. The input and / or ejection of a glass sheet from or into the rotating station 50 is carried out accordingly the manner in which the input and / or ejection of a glass sheet from the rotatable buffer station 70.

In the above description of the other lock station 100 it was assumed that these - like those in the FIGS. 7 to 10 Locking station 90 shown - is formed single track. But it is - as described above in the lock station 90 described above - possible to form the further lock station 100 two lanes, so that it then has two conveyor tracks and two support means, which are preferably oriented inclined opposite to the vertical, so that in turn the V-shaped Design is given. In the lock position of the lock station 90, one of the two support walls 53a or 53b then aligns with the support wall 103 and the second support wall 53b or 53a with the further support wall. The statements made on the two-lane design of the lock station 90 apply correspondingly to the further lock station 100.

The described device can also be designed according to the second embodiment, i. h., That the turning station 50 'is enlarged, so as to process also large glass panel 3A, 3B, as described with reference to the second embodiment. In this case, it is then advantageous that the further lock station 100 preferably has a length which also allows the discharge of large glass sheets 3A, 3B. It then corresponds to its function and its structure after the lock station 90. The turning circle K 'of the rotating station 50' is then given by its length and the length of one or preferably both extension devices 50b 'and 50c'.
