Description

Technology Field

[0001] The present invention relates to the manufacture of an insulating glass plate having a glazing bar insert. Such an insulating glass plate has long been manufactured by inserting a glazing bar insert into a frame-type spacer before placing a second glass plate on a spacer applied to a first glass plate. Background Technology

[0002] Insulating glass sheets of the type mentioned above are known, for example, from DE 10 2004 043 581 A1. The insulating glass sheet has a frame-type spacer made of a thermoplastic spacer strand. A mentine bar holder designed as a mentine bar endpiece having a means for fixing to the spacer (tapered pins) is disclosed. Additionally, DE 10 2019 123 700 A1 discloses an insulating glass sheet formed by arranging two paste-type spacer strands with the frame-type spacer placed on top of each other, and solidifying them so that their heights together form the height of the spacer. A spacer strand is applied to each of the two glass sheets. Before joining the two glass sheets, a mentine grid is inserted into the spacer strand of one of the glass sheets and attached to the spacer strand. After that, a second glass plate is placed on top of it, and a spacer and a glazing bar insert are positioned between the two glass plates.

[0003] Production takes place on a production line comprising several stations where various steps are performed during the assembly of insulating glass panels. One of these stations is the Muntin bar station, where glazing bar inserts are manually inserted by an operator. In practice, it is common to hang prefabricated glazing bar inserts on a trolley equipped with cantilever arms and push the loaded trolley to the Muntin bar station. The operator then removes the glazing bar inserts from the trolley and inserts them into the spacers of the glass panels standing at the Muntin bar station.

[0004] As already described in DE 10 2004 043 581 A1, handling glazing bar inserts is not entirely easy, especially when they are for larger insulating glass panels. The glazing bar inserts do not behave like a rigid structure before being inserted, which makes it difficult to place such an arrangement precisely in a predetermined position on the first attempt. In the process, the glazing bar inserts can deform and / or damage the thermoplastic spacers, which are still soft, when an attempt is made to place them within the space enclosed by the spacers. Therefore, attempts have always been made to avoid applying force to or deforming the spacer strands, which are made of a paste-like material that has not yet hardened after being applied to the first glass panel, so as not to damage the appearance of the spacers in the finished insulating glass panel. The problem to be solved

[0005] The object of the present invention is to improve the handling and transport of glazing bar inserts in connection with the manufacture of insulating glass plates, particularly during the automatic insertion of glazing bar inserts. means of solving the problem

[0006] The above objective is achieved by a support device having the features described in claim 1, a transport trolley having the features described in claim 7, and a method described in claim 12. Additional advantageous embodiments of the present invention are the subject of dependent claims.

[0007] A support device for holding a glazing bar insert for an insulating glass plate during a transport process according to the present invention includes a muntin bar end holding mechanism having a loading direction. The loading direction extends along the muntin bar of the glazing bar insert loaded on the support device. The glazing bar insert comprises at least one muntin bar. The glazing bar insert may consist of a single muntin bar. However, the glazing bar insert may also include an arrangement of several intersecting muntin bars. Such an arrangement is sometimes referred to as a "muntin grid." The muntin bar may be formed by an elongated and / or stretched muntin bar profile. The muntin bar may have two ends configured for attachment to a spacer. The muntin bar profile may be designed as a hollow profile. The muntin bar may also be composed of several muntin bar profiles. The muntin bar profiles may be thin-walled hollow profile rods. The glazing bar insert comprises at least one elongated montine bar profile having a montine bar end facing the spacer. The support device can be loaded with the glazing bar insert by engaging the glazing bar insert with a montine bar end holding mechanism in the region of the free end of the montine bar. The free end of the montine bar can be engaged with the support device along the longitudinal direction of the montine bar, particularly parallel to the longitudinal direction of the montine bar.

[0008] In a method for transporting a glazing bar insert in connection with the manufacture of an insulating glass plate according to the present invention, the glazing bar insert is positioned such that the at least one montine bar extends vertically. The glazing bar insert may have a long side and a short side, particularly when intended for an irregular insulating glass plate. Before being loaded into a support device, such a glazing bar insert may be positioned upright on the short edge of the glazing bar insert so that the long side extends vertically. The glazing bar insert is loaded into the support device by engaging the free end of the at least one montine bar with the support device along the loading direction until the glazing bar insert is seated at a positioning stop associated with the support device. The glazing bar insert may be inserted into the support device with the free end of the at least one montine bar, such that the long side of the glazing bar insert held by the support device extends vertically. The above support device is transported to an automatic montine bar station in such a manner that it is maintained in an upright position, particularly on a short corner, together with the glazing bar insert. The glazing bar insert is unloaded by removing it from the support device by a gripping device in the opposite direction of loading. The loading direction may coincide with a vertical line.

[0009] The glazing bar insert is then rotated by a gripping device so that at least one montine bar, particularly the long side of the glazing bar insert, is extended horizontally. When assembling the insulating glass panels, the glass panels are typically transported through a production line so that their long sides are extended horizontally. The glazing bar insert, particularly with its long side extended horizontally, is inserted into a frame-type spacer by an automatic montine bar station. The insulating glass panel may comprise at least two glass panels and a frame-type spacer made of a plastic-based material. The spacer may have been applied to the first glass panel by applying a paste-type spacer strand, which is known to solidify later, in a frame-type manner to the first glass panel. The spacer strand may be a paste-type spacer strand made of a thermoplastic material and / or a reactive crosslinking material that is subsequently solidified. The first glass plate having the spacer is supplied to a known montine bar station, for example via a horizontal conveyor, before the glazing bar insert is inserted. The montine bar station may be an automatic glazing bar insert assembly station. The montine bar station may include several processing heads. Each processing head is configured to receive a montine bar end and embed it in a spacer strand. After the glazing bar insert is inserted, the glass plate is transferred to a pressing station and connected to another glass plate, as is known, so that the spacer and the glazing bar insert are positioned between the two glass plates. In the finished insulated glass plate, the spacer and the glazing bar insert are placed between the two glass plates.

[0010] A transport trolley for transporting a plurality of glazing bar inserts for an insulating glass plate according to the present invention has a loading direction that can be oriented particularly along a vertical line. The transport trolley can be moved manually by a worker or operator. The transport trolley includes a plurality of support devices arranged side by side in a transverse direction to the loading direction, each support device being for a single glazing bar insert, particularly one positioned upright on its short edge. Each support device is assigned a positioning stop that defines the position of the glazing bar insert after the free end of the at least one montine bar is coupled to the support device along the loading direction during the loading process. Each support device can be loaded as a glazing bar insert by coupling the free end of the at least one montine bar to the support device along the loading direction until the glazing bar insert is seated at the positioning stop assigned to the support device. When loading the above support device, the positioning stop can limit the displacement of the glazing bar insert combined with the support device along the loading direction.

[0011] The present invention has significant advantages:

[0012] ● The above method can be used to automatically insert glazing bar inserts into frame-type spacers, particularly during the manufacture and / or assembly of insulating glass panels.

[0013] ● Only a single glazing bar insert is held on each support device. This enables alignment, orderly transport, and easy removal of the glazing bar insert. Additionally, it prevents the glazing bar insert from falling off the transport trolley and / or being damaged during transport.

[0014] ● The glazing bar inserts can be aligned in a sequence corresponding to the assembly order of the relevant insulating glass panels on the production line, already during the loading of the support devices and / or transport trolleys. This eliminates the need for alignment at the montine bar station, making automatic feeding there very easy to implement.

[0015] ● The end of the montine bar that rests on the positioning stop ensures that the glazing bar insert is in a defined position within the support device. This can facilitate, for example, the automatic removal of the glazing bar insert by a robotic arm.

[0016] ● The above support device is particularly suitable for holding glazing bar inserts of different designs and sizes. Small and large glazing bar inserts can be securely held and positioned on the same support device. Additionally, a glazing bar insert consisting of only a single montine bar can also be held and positioned on the same support device.

[0017] ● The above support device and transport trolley enable handling of upright positioned glazing bar inserts (including vertically positioned single montine bars), thereby enabling space-saving and safe transport of glazing bar inserts.

[0018] In a further embodiment of the present invention, when loading onto a support device, the lower free end of the at least one montine bar may be provided to be inserted into the support device from above. Upon unloading, the montine bar held within the support device by the lower free end may be grasped by a gripping device in its intermediate section, and the glazing bar insert may be withdrawn upward from the support device. The gripping device may rotate the glazing bar insert until the montine bar held therein extends horizontally. To this end, the gripping device may be rotatably mounted on a movable robot arm. The gripping device may include a connection for the robot arm. The gripping device may be coupled to a rotary drive and / or may include a rotary drive. Thus, the gripping device, after withdrawing the glazing bar insert from the support device, rotates it to the orientation required for insertion into the montine bar station. In particular, the gripping device can exclusively grip the glazing bar insert only in the middle section of the montine bar held by the support device during unloading. This enables a space-saving and simple design of the gripping device.

[0019] The gripping device may grip a montine bar with two pairs of grippers spaced apart from each other. Each pair of grippers may include two gripping elements. When gripping, the gripping elements may come closer together. To this end, each gripping element may be coupled to a gripping drive unit. The gripping device may include a gripping drive unit, for example, which is a pneumatic cylinder. A first gripping element of a first pair of grippers may be connected to a first gripping element of a second pair of grippers by a first connecting bridge. A second gripping element of a first pair of grippers may be connected to a second gripping element of a second pair of grippers by a second connecting bridge. This may simplify the synchronous gripping movement of the gripping elements in the two pairs of grippers. The two pairs of grippers may be spaced apart from each other in the longitudinal direction of the montine bar to be gripped. This spacing may be selected to be slightly greater than the maximum possible height of the cross montine bars and may be between 8 mm and 45 mm. This spacing can ensure that montine bars having a cross montine bar in the center can also be gripped in the middle. In an embodiment, this spacing may be variable. The latter may enable additional gripping of the cross montine bar. The gripping device may have a support for the cross montine bar. This can improve the take-out and transport of unstable glazing bar inserts or montine grids by the gripping device.

[0020] In a further embodiment of the present invention, the support device may comprise a housing having a base side, a loading side, and two side walls. The loading side is opposite to the base side. The side walls extend from the base side to the loading side. The loading direction is directed from the loading side to the base side. The housing has a recess and / or opening for a mentine bar end coupled to the support device in the area of ​​the base side. A positioning stop for the mentine bar end may be disposed in the area of ​​the recess and / or opening. The opening in the base side may extend into the side walls. The positioning stop may be contained within the support device. Alternatively, an external positioning stop may be assigned to the support device. The mentine bar end holding mechanism may comprise at least one clamping device. The clamping device is configured to clamp a glazing bar insert coupled to the support device in the area of ​​the free mentine bar end. The free end of the at least one mentine bar of the glazing bar insert may be coupled to the clamping device along the loading direction. After the support device is loaded, the montine bar end clamping device can clamp the free end of the montine bar. The montine bar end holding mechanism may have a first clamping device and, downstream therefrom in the loading direction, a second clamping device. The support device may also be mounted on a conveyor belt or conveyor chain to transport the glazing bar insert to the montine bar station.

[0021] In a further embodiment, the clamping device may include at least two mutually facing mentine bar clamps. In particular, the clamping device may include at least one pair of two mentine bar clamps positioned facing each other. A second pair of mentine bar clamps may be positioned downstream of the first pair of mentine bar clamps in the loading direction. Each mentine bar clamp may form a guide means and / or holding means for the mentine bar of the glazing bar insert. The mentine bar clamps may include rollers and / or slide guides. The mentine bar clamps may clamp and hold the mentine bar from opposite sides. At least one of the mentine bar clamps may be movable transversely to the loading direction and / or transversely to the longitudinal direction of the mentine bar to be clamped. Thus, the mentine bar combined with the mentine bar end holding mechanism may be clamped transversely to the loading direction. This can ensure that the glazing bar insert is securely held during transport. Unintended detachment from the support device can be prevented. The movable mentine bar clamp can be spring-loaded in the direction of another mentine bar clamp. The clamping device may have an insertion area that tapers in the loading direction. In the insertion area of ​​the clamping device, the distance between the two mentine bar clamps may be reduced when viewed in the loading direction. At least one of the two mentine bar clamps may have a curved or inclined section in the insertion area. This ensures that when the mentine bar end is inserted into the mentine bar end holding mechanism, the mentine bar end pushes out the spring-loaded mentine bar clamp and thus is easily clamped by the two mentine bar clamps facing each other. This enables a simple design of the support device, as no driving unit is required to open and close the clamping device.

[0022] In a further embodiment of the present invention, the transport trolley may have a coupling for engaging the transport trolley with an automatic montine bar station. This allows the transport trolley, pushed by an operator to the montine bar station, to be parked there at a defined position, thereby enabling the glazing bar insert to be automatically removed. The transport trolley may have at least one additional support for a large glazing bar insert. The additional support may include an extendable support plate. The support plate may support the glazing bar insert held in the support device from below. The additional support may include a side guide. The side guide may be positioned over the support devices. Each support device may be assigned a side guide. The side guide may support the glazing bar insert laterally in the plane to which the glazing bar insert extends. The transport trolley may include 20 to 80, particularly 45 to 55, support devices. Each of the above support devices may have a montine bar end holding mechanism having a loading direction for an uprightly positioned glazing bar insert. The loading direction may be oriented vertically downward so that the lower free end of the vertically extending montine bar may be coupled to any one of the support devices of the transport trolley. All support devices of the transport trolley may have the same design. The positioning stop may extend transversely to the loading direction, particularly along all support devices of the transport trolley. The positioning stop may be formed by a positioning surface on the base plate of the transport trolley. The positioning stop may be configured to position the glazing bar insert so as to restrict the insertion movement of the montine bar into the support device in the insertion direction. The transport trolley may have a cleaning channel for the positioning stop. The cleaning channel may be formed by recesses and / or openings within the housings of the support devices arranged side by side.The above cleaning channel can be extended laterally in the loading direction.

[0026] FIG. 1 illustrates a rectangular insulating glass plate (1) comprising a first glass plate (2), a second glass plate (3), a frame-type spacer (4), and a glazing bar insert (5). The glazing bar insert (5) is designed as a montine cross and includes a horizontally extending montine bar (6) and a cross montine bar (7). The montine bar (6) has two montine bar ends (8) attached to the spacer (4). The cross montine bar (7) also has two montine bar ends (9) attached to the spacer (4). The montine bars (6, 7) are hollow profiles made of thin walls. The long sides of the insulating glass plate (1) and the glazing bar insert (5) extend horizontally. The spacer (4) is formed from a paste-like strand of a plastic-based material that solidifies after being applied to the glass plate (2), as is known.

[0027] FIG. 2 illustrates a transport cart (10) according to the present invention, which has a plurality of support devices (11) according to the present invention. The transport cart (10) has a frame (12) made of steel profiles and can be moved on four rollers (13). The rollers (13) can be designed as swivel casters or fixed casters as required. Two handles (14) are attached to the frame (12) and can be used by a worker to move the transport cart (10). The support devices (11) are placed on the base plate (15) of the transport cart (10), and various glazing bar inserts can be loaded from top to bottom along the loading direction (B). In FIG. 2, the first support device (11) is loaded with a montine cross (5) having a vertically extending montine bar (6) and a cross montine bar (7). The second support device (11) is loaded with a large upright montine grid insert (5') consisting of two vertical montine bars (6', 6") and two cross montine bars (7', 7"). During loading, the glazing bar insert (5, 5') is inserted into the support device (11) along the loading direction (B). The lower free end (8) of the montine bar (6) and the lower free end (8') of the montine bar (6') are inserted into their respective support devices (11) and joined with their respective support devices (11).

[0028] The transport trolley (10) has additional support members (16) for guiding and supporting the ends (9, 9', 9") of the cross montine bars (7, 7', 7"), particularly for large glazing bar inserts. The additional support members (16) extend along a vertical line and are attached to the frame (12) at spaced intervals. The additional support members (16) may be formed as a bar or a band, particularly an elastic band. Below the base plate (15), a separate additional support member (17) in the form of a support plate is positioned, particularly for large glazing bar inserts (5'). The additional support member (17) may be extended by pulling along the arrow (C). After extension, the additional support member (17) may support the large montine grid insert (5') at the lower free end (8") of the vertically extending montine bar (6") that is not coupled with the support device (11). See FIG. 2.

[0029] Each support device (11) has a housing (20) having a base side (21), a loading side (22), and two side walls (23, 24), see FIGS. 3 and 4. The housing (20) is mounted on a base plate (15) with its base side (21). The housing (20) has a recess (25). A positioning stop (26) is placed in the area of ​​the recess (25). The positioning stop (26) is schematically illustrated in FIG. 4 and is formed on the upper side of the base plate (15) in the transport cart (10). See FIG. 2. In the transport cart (10), the recess (25) of the support devices (11) arranged side by side forms a cleaning channel (27) for cleaning the positioning stop (26). If contaminants fall from above into the support device (11), they may accumulate on the positioning stop (26) and impede the precise positioning of the glazing bar insert (5, 5'). This also applies if chips are still present on or inside the Muntin bar end (8, 8') inserted into the support device (11). The cleaning channel (27) makes the positioning stop (26) easily accessible and allows it to be cleaned in a simple manner, for example by blowing compressed air through it.

[0030] The support device (11) has a montine bar end holding mechanism (30) consisting of two clamping devices (31, 32). The second clamping device (32) is positioned downstream of the first clamping device (31) in the loading direction (B). The clamping device (31) includes two montine bar clamps (33, 34) facing each other. The clamping device (32) includes two montine bar clamps (35, 36) facing each other. Each montine bar clamp (33, 34, 35, 36) is formed by a clamping roller mounted freely rotatable on an axis (37). Each axis (37) is mounted on a sliding piece (38) mounted within the housing (20) so as to be laterally moved in the loading direction (B). Each sliding piece (38) is spring-loaded and pressed against the montine bar (6) by a helical spring (39). When the montine bar (6) is pulled out of the support device (11), the distance between the montine bar clamp (35) and the montine bar clamp (36) and the distance between the montine bar clamp (33) and the montine bar clamp (34) decrease. The curved peripheral surfaces of the montine bar clamps (33, 34) form an insertion area (40) that tapers in the loading direction (B).

[0031] When loading the support device (11), the lower free end (8) is inserted into the support device (11) in the loading direction (B). Due to the insertion area (40), the mentine bar end (8) pushes the two mentine bar clamps (33, 34) away from each other against the force of the helical springs (39) and enters between the mentine bar clamps (33, 34). This also occurs in the mentine bar clamps (35, 36) as the mentine bar end (8) is further inserted into the mentine bar end holding mechanism (30). The insertion movement of the mentine bar end (8) in the loading direction (B) is limited by the fact that the mentine bar end (8) comes into contact with the positioning stop (26). The mentine bar end (8) coupled with the support device (11) is then in the position shown in FIG. 4 and is fixed within the mentine bar end holding mechanism (30) in a predetermined and secure manner.

[0032] FIG. 7 illustrates an automatic montine bar station (41) for inserting glazing bar inserts (5, 5'). A loaded transport cart (10) is parked at a defined position at the montine bar station (41). To this end, the transport cart (10) has a coupling (42) for connecting to the montine bar station (41). A robot arm (43) assigned to the montine bar station (41) can then unload the glazing bar inserts (5, 5') contained in the transport cart (10) and transfer them to the montine bar station (41).

[0033] The robot arm (43) includes a gripping device (50) illustrated in FIG. 8. The gripping device (50) has four gripping elements (51, 52, 53, 54) for gripping a Muntin bar (6, 6') at its center. The gripping elements (51, 52) form a first gripper pair (55). The gripping elements (53, 54) form a second gripper pair (56). The first gripping element (51) of the first gripper pair (55) is connected to the first gripping element (53) of the second gripper pair (56) via a connecting bridge (57). The second gripping element (52) of the first gripper pair (55) is connected to the second gripping element (54) of the second gripper pair (56) via a connecting bridge (58). The distance between the gripping elements (51, 52, 53, 54) can be varied along the double arrow (D) by the pneumatic drive unit (59). Due to coupling by the connecting bridge (57, 58), the two gripper pairs (55, 56) open and close synchronously when the montine bar (6') is grasped by the gripping device (50). Refer to FIG. 9. The second gripper pair (56) is spaced apart from the first gripper pair (55), so that the montine bar (6) can be grasped at the center where the cross montine bar (7) is located. Refer to FIG. 10. A support (60) for the cross montine bar (7) is placed between the gripper pairs (55, 56), which can stabilize the glazing bar insert (5) when the robot arm (43) moves. The gripping device (50) is attached to the robot arm (43) via the connecting part (61). Otherwise, the robot arm (43) is designed as is known and therefore does not need to be described in detail.

[0034] In order for the glazing bar insert (5') located within the transport carriage (10) by the automatic montine bar station (41) to be inserted into the spacer (4), the robot arm (43) moves the gripping device (50) to the center of the montine bar (6'), and the lower free end (8') of the montine bar (6') is coupled with the support device (11). The gripping device (50) grasps the montine bar (6') as shown in FIG. 9 and lifts the glazing bar insert (5') in the opposite direction of the loading direction (B), so that the lower free end (8') of the montine bar (6') is pulled upward out from the support device (11). This is shown in FIG. 5. At this time, the end of the montine bar (9', 9") located within the additional support (16) is guided upward within the additional support (16). Then, the robot arm (43) moves the gripping device (50) laterally in the loading direction (B) and moves the end of the montine bar (9', 9") out of the additional support (16), see FIG. 6. The glazing bar insert (5') is still positioned upright. The robot arm (43) then rotates the gripping device (50) so that the montine bar (6') extends horizontally.

[0035] The Muntin bar station (41) comprises one or more single-track horizontal conveyors (70), which are formed by a line of several drivable conveying rollers (71). See FIG. 7. Such horizontal conveyors (70) are known. A glass plate (2) stands on the horizontal conveyor (70) with its lower edge. The Muntin bar station (41) has a support wall (74), which, as is known, has an angle of 6° to 8° relative to the vertical to prevent the glass plate (2) from accidentally tipping forward and to support the glass plate (2) standing on and leaning against the horizontal conveyor (70). In FIG. 7, the glass plate (2) is transported into the Muntin bar station (41) from the left, and its long side extends horizontally, see FIG. 1. The Muntin bar station (41) comprises several processing heads (76) that can be moved parallel to the support wall (74). The montine bar station (41) includes multiple drive units coupled to a control system for motor-driven displacement of the processing head (76). Before the glazing bar insert (5') is inserted, the processing head (76) is moved to positions required to accommodate the montine bar ends (8', 8", 9', 9") according to the dimensions of the glazing bar insert (5'). Now, the glazing bar insert (5') can be transferred from the robot arm (43) to the montine bar station (41). In this process, the montine bar ends (8', 8", 9', 9") are taken in by the processing head (76), and the glazing bar insert (5') is positioned parallel to the support wall (74). The gripping device (50) is then opened and moved away from the glazing bar insert (5'). The gripping device (50) is moved back to the transport cart (10) by the robot arm (43) to unload the next glazing bar insert (5).

[0036] The processing head (76) is moved toward the support wall (74) along with the glazing bar insert (5') held therein, and is moved closer to the support wall (74) and the glass plate (2) standing there. The glazing bar insert (5'), oriented parallel to the glass plate (2), is inserted transversely into the glass plane into the space enclosed by the frame-type spacer (4) and into the spacer (4). After all the montine bar ends of the glazing bar insert (5') are fastened, all processing heads (76) are moved away from the support wall (74). The glass plate (2) with the glazing bar insert (5') inserted into the spacer (4) is then transported out of the montine bar station (41) by the horizontal conveyor (70). This empties the montine bar station (41) again, allowing the next glazing bar insert (5) to be inserted.
