Description

The invention relates to a plant for the production or manufacture and treatment of glazing beads according to the preamble of claim 1 and a method using such a plant according to the preamble of claim 12. Such a plant and such a method is known from DE 198 20 409 A1 known. In order to produce window sashes, workpieces made of pre-machined wooden shells and associated glazing beads are profiled. The wooden body (workpiece) is first pre-profiled in a first operation in a molding machine and thereby separated a raw or partially profiled glass strip from the later fold of the window frame or sash. In further operations, the window sash parts are finished profiled and finished and profiled the glass bar finished and cut to the correct length and miter. However, such an approach is cumbersome.

The invention has the object of providing the generic system and the generic method in such a way that glazing beads can be easily made from a workpiece, separated and treated further.

This object is achieved in the generic system according to the invention with the features of claim 1 and in the generic method according to the invention with the features of claim 12.

Advantageously, the processing machine is a molding machine with which the workpieces can be processed on all four sides in one pass. At the same time, the glass strip is also cut out of the workpiece. According to the invention, the one tool sits on a horizontal spindle, which is located in the transport path of the workpiece through the processing machine in the area above the workpiece. With this tool, a first cut can be produced during the passage of the workpiece in the upper side, with which the glass strip is partially separated from the workpiece. Preferably behind this tool, seen in the feed direction of the workpiece through the processing machine, there is the other tool, which according to the invention has a rotational axis lying obliquely to the transport direction of the workpiece. Since the two tools are spaced one behind the other in the transport direction of the workpiece, the required cuts in the workpiece can be provided easily and accurately.

The other tool with the oblique axis of rotation according to the invention is composed of a saw blade and a frusto-conical milling tool. This forms a chipper, with which the glass strip can be processed on the underside.

With the disc-shaped saw blade of the required separating cut in the workpiece for separating the glass strip is made. According to the invention, the severed glass strip and the remaining part of the workpiece exit simultaneously from the outlet of the processing machine. Advantageously, then only the glass bead is detected and further treated, while the remaining part of the workpiece is transported by a transport device for further processing.

In a further embodiment of the system according to the invention, the processing machine is followed by at least one depositing device. It is provided with at least one, preferably with two gripper units with which the glass strips of the processing machine can be removed and stored on at least one tray.

In a preferred embodiment, the one gripper unit is a 2-axis gripper unit, with which the glass strip can be transported in two mutually perpendicular directions. This gripper unit takes advantage of emerging from the machine, finished profiled glass bead.

Preferably, the other gripper unit is a 3-axis gripper unit, which can transport the glass strip in three mutually perpendicular directions.

The two gripper units are adjustable in a preferred embodiment in a transfer position, in which one gripper unit passes the glass strip of the other gripper unit. The one gripper unit takes over the glass strip when leaving the processing machine and transports it to the transfer position. The second gripper unit takes over the glazing bead. Once the transfer has taken place, the first gripper unit can return Move back to the processing machine to record the next glazing bead. During this time, the glass strip can be supplied by means of the second gripper unit of a further processing and / or treatment.

The one gripper unit advantageously detects the glass strip at the outlet of the processing machine and transports it to the transfer position. As long as the glass strip has not yet been completely separated from the workpiece, the traversing speed of the first gripper unit is synchronized with the feed rate of the glass strip in the processing machine. As soon as the glass strip has been completely separated off and has possibly been completely pulled out of the processing machine by the first gripper unit, the gripper unit can now transport the glass strip to the transfer position independently of the feed speed of the processing machine.

The plant is provided in a preferred embodiment with at least one miter saw, with the glass bar, if necessary, a miter cut can be generated. A miter saw should also be understood as a chipper with which a miter can be machined on the glazing bead.

Preferably, the plant has a left and a right miter saw, so that with these two miter saws, a left and a right Miter cut can be generated on the glass strip.

In order for a clean miter cut can be made, the system is provided in an advantageous training before the respective miter saw, each with a clamping station. The glass strip is clamped in the clamping stations for the miter cut. Due to the clamping of the glazing bar in these two clamping stations results in a clean and accurate miter cut.

Preferably, the second gripper unit, with which the glazing bead of the miter saw and the associated clamping stations is supplied, advantageously switched unpressurized. This results in a small air gap between the clamping elements of the second gripper unit and the glass strip. The second gripper unit can thereby be moved along the glass strip in the X direction, as long as the glass strip is clamped in the clamping stations in the miter saws. Thus, it is possible that the second gripper unit is moved along the glass strip in the direction of its right end during the time in which, for example, a miter cut is produced with the left miter saw, so that the second gripper unit can clamp the glass strip in this end region, to transport the glazing bead to the right miter saw after creating the miter cut using the left miter saw. Since the clamping of the glazing bar by the second gripper unit takes place near the right end of the glazing bead, it can be precisely inserted into the clamping stations in front of and behind the right miter saw.

Advantageously, the storage device is provided with storage compartments for the glazing beads, in which the glazing beads can be ordered and stored exactly.

The storage compartments can be adjusted in height in Z-direction.

The system is advantageously provided with at least one slide, with which the lying in the storage compartments glass strips can be moved in recordings.

The recordings are advantageously arranged above and next to one another, so that a large number of glass strips can be accommodated in a small space. Since the storage compartments are adjustable in height, the glass strips can be easily inserted into the superimposed receptacles.

The recordings are advantageously provided on a trolley, which can be moved away after filling the recordings, so that the glazing beads are made available for further use, for example to produce window sashes.

In the method according to the invention, the glass strip emerging from the outlet of the processing machine is detected by the gripper unit. At this time, the glass bead has not yet been completely separated from the workpiece. Therefore, the gripper unit is moved synchronously with the feed of the processing machine before it has detected the end of the glass strip.

As soon as the glass strip has been completely separated from the workpiece and optionally pulled out of the processing machine with the gripper unit, it is fed by means of this gripper unit to processing units with which the glass strip can be processed.

Advantageously, the processing units miter saws or chipper, with which the glass strip is cut to finished lengths and mitred.

In an advantageous method guide, the gripper unit transports the glass strip to a miter saw. The glass strip is clamped in front of and behind the miter saw, if necessary, so that a clean miter cut can be made. As long as the miter cut is performed, the clamping of the gripper unit is depressurized. This results in a small air gap between the clamping elements of this gripper unit and the glass strip. As a result, the gripper unit can be moved along the glass strip in the direction of the other end of the glass bead. There, the gripper unit can clamp the glass strip at a distance from the end again, so that the glass strip after generating the one miter cut to the opposite miter saw can be transported to make the miter cut now at the other end.

As soon as the required miter cuts have been produced, the gripper unit is advantageously moved downwards in the half-length along the glazing bead when the clamping is switched without pressure. There, the glass strip is clamped with this gripper unit. Then the clamp can be released in front of the miter saw. Then the glass strip with the gripper unit can be placed in the storage compartments.

In a preferred embodiment, the glass strip is transported with the gripper unit in a transfer position. Here, the glass strip is handed over to another gripper unit.

The system is used to cut out glazing beads from workpieces, which are referred to below as wooden cantilevers, as well as to pre-work the wooden shells for further processing of window sash and window frame parts. For this purpose, the system has a processing machine 1, which is advantageously a molding machine. In it, the wooden shells are processed as they pass through and the glass bar is cut out of them. The basic structure of the moulder is based on Fig. 12 explained. The moulder has a machine table on which the wooden shells 2 are transported by means of transport elements, preferably feed rollers, through the machine. The feed rollers are under pressure on the top of the wooden shells 2 and promote them through the machine. The moulder has in the inlet area a lower horizontal spindle 3, on which a tool sits, with which the underside of the wood sill 2 is processed. In the transport direction 4 behind the lower spindle 3, the moulder has a vertical right-hand spindle 5, on which a tool sits, with which the right in the transport direction longitudinal side of the wood sill 2 can be edited. In the transport direction 4 behind the right spindle 5 is a left spindle 6, which carries a tool for processing the left in the direction of transport 4 longitudinal side of the timber frame 2.

The left-hand spindle 6 is followed by two spaced-apart upper horizontal spindles 7 and 8, which carry tools with which the upper side of the wooden skirt 2 can be machined.

In the transport direction 4 at a distance behind the upper spindle 8, the molding machine is provided with a lower horizontal spindle 9, with the tool, the underside of the wood sill 2 can be edited. After all the moulder is provided with a glass bead saw 10, with the from the wood sill 2 in a manner to be described, a glass strip can be cut out. The axis of rotation of the glass bead saw 10 is at an angle to the vertical.

Based on Fig. 13 to 15 showing the wooden sill 2 from the outlet side of the moulder 2, the separation of a glazing bar 11 from the wooden sill 2 will be described. It is processed as it passes through the molding machine 1 in a known manner on all four sides. With the sitting on the right spindle 5 tool 12, which is rotatable about the axis 13, the right longitudinal side of the wood sill 2 is processed. In this case, the right longitudinal side 14 is processed as an example, so that near the top of a projecting web 15 stops. As soon as the wooden skirt 2 reaches the working area of the upper horizontal spindle 8, the tool 16 seated on it, which is rotatable about a horizontal axis lying perpendicular to the transporting direction 4, inserts into the upper side 18 a section running in the longitudinal direction of the wooden skirt 2 . running profiling introduced. The tool 16 is designed or profiled in such a way that the glass strip 11 to be separated out has the required outer contour in this area. Optionally, this profiling can be divided into the two upper spindles 7, 8, for example, can already be performed with the upper spindle 7 a saw cut, which is only nachprofiliert with the spindle 8. Since the wooden body is still very solid in the area of the upper spindles, a very good surface quality is achieved for this finished profiling. The pages processed by the upper tools are the later visible sides in the installed state of the glass strip 11. The usual today cutting raw glass strips takes place in that already on the right spindle a horizontal saw cut on the width of the raw glass strip and the bar already on the upper spindle or separated by using a separate glass bead saw from above. In this procedure, a high-quality machining with the upper tool is not possible because the bar with the previously introduced horizontal saw cut with no longer sufficient stability is associated with the wooden body. As a result, the glass strip can be excited during processing, for example, to vibrations.

Finally, during the further passage of the wooden skirt 2 through the molding machine with the glass bead saw 10, the glass strip 11 is completely separated from the wood skirt 2. The axis of rotation 19 of the glass bead saw 10 is an example at an angle of about 65 ° to the vertical. The glass bead saw 10 and the tool sitting thereon are designed so that with her the glass strip 11 processed at the bottom and at the same time is completely separated from the wood sill 2, wherein the glass strip 11 receives the required final profile. Depending on the design of the glass strip 11, the glass bead saw 10 may have different training. In the exemplary embodiment, it is composed of a saw blade 10a and a frusto-conical milling tool 10b, which may be a chipper, for example.

In the FIGS. 13 and 14 is indicated by dashed lines the end profile of the glass strip 11 after the separation of the glass strip 11. In Fig. 15 is an exemplary end profile of the wood sill 2 shown with dashed lines. How out Fig. 15 it can be seen, the glass bead saw 10 is formed so that it has a distance from the end profile 20 of the wood sill 2. As a result, there is still sufficient material available to produce the end profile with a corresponding tool on this right long side of the wooden skirt 2. This is advantageously achieved in that the separating cut is made obliquely to the horizontal plane. This is the case when the axis of rotation 19 as described above is at an angle to the vertical.

With the moulder described, the glass strip 11 is cut out with the required finished Längsprofilierung of the wood sill 2 in a single pass of the wood sill 2. As a result, the glass strip 11 can be manufactured inexpensively.

Fig. 16 shows by way of example how with the remaining after the separation of the glazing bar 11 and finished in a further processing step part of the wooden frame 2 and the glass strip 11, a window sash can be produced. Fig. 16 shows a part of the lower frame part of the window sash with a part of the wooden skirt 2, on which the edge of a window pane 21 rests. It is supported in the edge region on a support surface 22 of the wooden skirt. On the opposite side, the window pane 21 is secured by the glazing bar 11, which engages with the protruding web 15 in a recess 23 of the wooden skirt 2. This overlap makes it possible to compensate for length tolerances of the glazing bead and window sash without this becoming visually apparent. This is called a rebated glazing bead.

The window pane 21 is sealed by two seals 24, 25, which are introduced between the wooden skirt 2 and the glass strip 11. To form corresponding receiving spaces for the seals 24, 25, the wooden skirt 2 and the glazing bead 11 are provided on their sides facing the window pane 21 with corresponding oblique surfaces 26, 27. The inclined surface 27 of the glass strip 11 is the surface which is produced during the separation by the glass bead saw 10 as a result of lying at an angle of rotation.

Since in the molding machine 1 the glazing bead 11 is separated from the wooden scant 2 in the manner described, out of the spout 28 (FIG. Fig. 1 ) of the molding machine 1, the finished profiled glazing bead 11 and the remaining part of the pre-profiled wooden skirt 2 from. The wooden skirt 2 reaches a transport device 29, which is advantageously an endlessly circulating conveyor belt. With him, the wood sill 2 further processing is supplied or, for example, transported to a (not shown) collection point in which the wooden shells 2 are stored for further use. For the finished glazing beads 11, a clipboard 30 is provided, on which the glazing beads 11 are deposited. For this purpose, two gripper units 31, 32 are provided.

The gripper unit 31 (FIG. Fig. 4 ) is movable along a rail 33 by means of a carriage 34 in the X direction. For this purpose, a drive motor 35 is provided. On the carriage 34, a carrier 36 is adjustable perpendicular to the X direction in the Z direction. He has two clamping elements 37, 38, with which the glass strip 11 can be clamped ( Fig. 7 ). The carrier 36 can be connected via a motor 39 (FIG. Fig. 4 ) are driven. The lower clamping element 38 is a support strip, which is rigidly connected to the carrier 36 and on which the glass strip 11 rests in the clamping position. The support bar has an upright bearing surface 88, on which the glass strip 11 rests laterally in the clamping position. The upper clamping element 37 is adjustable in the Z direction. The clamping element 37 is seated on two guide elements 40, which can be moved by means of a drive unit 41 in the Z direction. The drive unit 41 is seated on a boom 42 of the carrier 36. The drive of the drive unit 41 is preferably a pneumatic cylinder, not shown.

The gripper unit 31 forms a 2-axis gripper, which can be moved in the X and Z directions.

The gripper unit 32 forms a 3-axis gripper, which can be moved in the X, Y and Z directions. The gripper unit 32 has a carriage 43 which is movable along a rail 44 in the X direction. It sits with its two ends in the Y-direction extending cross members 45, 46, along which the rail 44 can be moved in the Y direction. The cross members 45, 46 sit on the upper ends of columns 47 to 50, which stand up on the ground. The cross members 45, 46 and columns 47 to 51 are components of a machine frame. On the two columns 49, 50, the rail 33 is attached, along which the gripper unit 31 can be moved in the X direction. The rail 33 is located with a such a distance below the cross members 45, 46, that the gripper unit 31 does not come into collision with the cross members when moving in the X direction.

To move the carriage 43 along the rail 44, a drive 51 is provided. Slidable in the Z direction, a vertical carrier 52 is mounted on the carriage 43, which carries two clamping elements 53, 54 at the lower end. The lower clamping element 54 is formed as a support bar, on which the glass strip 11 rests in the transport position. The support bar 54 also has an upright abutment surface 83 (FIG. Fig. 9 ), on which the glass strip 11 rests laterally in the clamping position. The upper clamping element 53 can be adjusted by means of a drive unit 55 in the Z direction. The drive unit 55 with the associated guides is designed similarly to the drive unit 41 with the guides 40.

The gripper unit 32 is provided with a further clamping element 89, which is provided on a pivot arm 90. It is pivotally mounted on the carrier 52 about a horizontal axis 91 extending in the X-direction. In the area between the pivot axis 91 and the clamping element 89 engages the pivot arm 90, a piston rod 92 of a drive unit 93 which is pivotally mounted at the free end of a support arm 94 about a horizontal axis 95 lying in the X direction. The support arm 94 projects transversely from the support 52 to which it is attached. With the clamping element 89, the glass strip 11 can be clamped on the left side. All clamping elements 53, 54, 89 are approximately at the same height, based on the clamped glass strip eleventh

The gripper unit 32 can be moved along the rail 44 in the X direction. The rail 44 in turn can be moved in the Y direction along the mutually parallel cross members 45, 46. The carrier 52 with the clamping elements 53, 54, 89 can be moved in the Z direction.

In the area between the columns 47 to 50 is the clipboard 30, on which the glass strips 11 are stored or stored. The clipboard 30 is height adjustable in the Z direction. For this purpose, the clipboard 30 can be mounted adjustable in height, for example, on two or more of the columns 47 to 50.

As it turned out Fig. 11 results, the clipboard 30 in the X direction extending storage compartments 56, in which the glass strips 11 are stored. The storage compartments 56 may be formed, for example, by a correspondingly shaped sheet metal. So that the gripper unit 32 can reliably deposit the glazing beads 11 in the storage compartments 56, adjacent storage compartments are located next to one another at a distance in the X direction. In this area, the gripper unit 32 can retract with the clamping elements 53, 54, 89 in order to be able to deposit the respective glass strip 11.

In the region of the cross member 45, a left miter saw 57 or processing unit and opposite in the region of the cross member 46 on the pillar 49, a right miter saw 58 is provided on the column 50. With the two miter saws 57, 58 11 miter cuts can be attached if necessary at the ends of the glass strip. The left miter saw 57 ( Fig. 9 ) has an about an axis transverse to the X direction rotatable circular Zerspaner 59, with which the glass strip 11 can be machined at one end miter. The use of a chipper 59 instead of a circular saw blade has the advantage that miter cuts are not produced. The chipper 59 is located in a protective hood 60. The circular chipper 59 sits on a shaft driven by a drive unit 61. The drive unit 61 is mounted on a carrier 62, which is held on the cross member 45.

In the area in front of the miter saw 57 is a clamping station 63, which has a clamping element 64 which is adjustable in the Y direction, and a clamping element 71 from above. The clamping station 63 with the clamping elements 64, 71 is located, seen in the transport direction 4 of the timber frame 2 through the molding machine 1, on the left side of the glass bead and before Miter saw 57. Behind the miter saw 57, a further clamping station 84 is provided which has two clamping elements 85,86. With the clamping element 85, the glass strip 11 is clamped on the left side. The clamping element 86 engages over the glass strip 11 and clamps it from above.

The right miter saw 58 ( Fig. 10 ) has a drive unit 65 with which a saw blade 66 can be rotatably driven. The saw blade 66 is located below a protective hood 67. The drive unit 65 is mounted on a carrier 68, which is fastened to the pillar 49. The axis of rotation of the miter saw 58 is again oblique to the X direction, but opposite to the axis of the opposite left miter saw 57 opposite.

In the area in front of and behind the miter saw 58, a clamping station 69 is likewise provided, which has at least one clamping element 70 which is adjustable in the Y direction for the lateral clamping of the glass strip 11. With it the glass strip is clamped laterally both before and after the saw. With the clamping element 72 in front of the miter saw 58, the glass strip 11 is clamped from above. The clamping stations of the two miter saws 57, 58 are suitably arranged fixed system. The mounting of the clamping stations 63, 69 is in Fig. 9 and 10 not shown in full for the sake of clarity.

The glass strips 11 deposited on the clipboard 30 are removed by means of a slide 73 (FIG. Fig. 3 ) is supplied to a fan carriage 74, the above and juxtaposed tubular receptacles 75 for the glazing beads 11 has. The slider 73 is formed so that it can engage in the storage compartments 56 and rests on them, so that it can reliably move the therein glass strips in the receptacles 75 of the fan tray 74. The number of located on the clipboard 30 storage compartments 56 in the Y direction corresponds to the corresponding number of receptacles 75 of the fan tray 74 in a plane. As in Fig. 3 is exemplified, the in the trays 56 of the clipboard 30th located glass strips 11 at the same time pushed into the receptacles 75 of the fan carriage 74 with the slider 73. The slider 73 extends in the Y direction and is displaceable at both ends along each of an X-directionally extending rail 76, 77. The slider 73 can be driven, for example, by means of belts 78 which are located on both sides of the rails 76, 77 such that the slider 73 is moved in the direction of the arrow 79 (FIG. Fig. 3 ) can be moved to push away the glazing beads 11 in the receptacles 75 as well as in the opposite direction. Since the clipboard 30 is height-adjustable in the Z-direction, it can be positioned relative to the compartment carriage 74 so that each floor of the compartmentalized carriage 74 can be filled with the glazing beads 11.

The compartment car 74 is movable so that it can be driven away when sufficiently filled to remove the glazing beads 11 for further use. The compartment cart 74 is thus placed between the columns 47, 50 (FIG. Fig.1 ) moved up to the clipboard 30 and optionally fixed that the glazing beads 11 can be easily moved from the storage compartments 56 into the receptacles 75.

On the back of the miter saws 57, 58 facing away from the clipboard 30 having storage unit is a chute 80 ( Fig. 2 ), in the Fig. 1 for the sake of clarity is not shown. It extends between the columns 47, 48 obliquely backwards and downwards and serves to transport the raw glass strips arising during the machining process into a rough-bar cart 81. The Rohleistenwagen 81 is also mobile.

In the molding machine 1, the wood trim 2 is processed on its four sides in the manner described and the glass strip 11 separated and simultaneously profiled. The profiled wooden skirt 2 and the profiled glass strip 11 emerge from the outlet 28 of the molding machine. The glazing bead 11 is fed in a manner to be described with the two gripper units 31, 32 to the miter saws 57, 58 to the miter cuts, if necessary, perform. Subsequently, the finished sawn glazing beads 11 are stored defined on the clipboard 30. With the slider 73, the glazing beads 11 are then pushed into the receptacles 75 of the fan tray 14.

Since the glazing beads 11 and profiled in the molding machine 1 wooden shells 2 are then joined together to form the window sash, as based on Fig. 16 has been explained, the glazing beads 11 and the wooden shells 2, from which they have been cut out, laid down defined so that the glazing strips 11 are joined together with the associated wooden shells 2 during subsequent assembly to the window sash. This results in a very uniform picture of the sash.

The assignment of glazing bead and wooden frame is easily possible via a corresponding computer-controlled storage.
The miter saws 57, 58 may be arranged at a fixed angle, preferably of 45 °, obliquely to the longitudinal axis of the glass strip 11. It is advantageous, however, if the miter saws 57, 58 are set in different inclinations. In this case, the miter saws 57, 58 are pivotable about a vertical axis. During the sawing process, the glazing beads 11 are reliably clamped so that a clean miter cut can be made.

When passing the wooden beam 2 through the molding machine 1, the glazing bead 1 is separated from the wooden scant 2 by the tool 10 seated on the last spindle. The axis of rotation 19 of this glass bead saw 10 is arranged obliquely ( Fig. 4 . 5 . 12 and 15 ). The glass bead saw 10 has her downstream in the direction of passage a riving knife 96, which additionally forms a support and with which the glass strip 11 can be separated and guided cleanly out of the wood sill 2. A pressure roller, not shown, directly after the glass bead saw can if necessary press the glass strip 11 on this edition, so that the end of the glass strip at the time to which the Glazing bead is completely separated from the wooden body, safely guided and held.

The gripper unit 31 is positioned at the outlet 28 of the molding machine 1 so that its clamping elements 37, 38 engage over the glass strip at the top and bottom and then can tension.

Since the glass strip 1 are transported with the wooden frame 2 by the transport elements of the molding machine 1 from the outlet 28, the machine feed is taken over by the drive of the gripper unit 31 in the X direction. For this purpose, a control (not shown) is provided which synchronizes the transport speed of the gripper unit 31 with the feed speed of the molding machine. After synchronization, the clamping elements 37, 38 grasp the glass strip 11 at a distance from its front end in the feed direction, by virtue of the upper clamping element driving downwards, whereby the glass strip is clamped at the top and bottom. The distance from this front Glasleistenende is for example about 120 to 150 mm. For example, the shortest glazing bead may be 380 mm long and the longest glazing bead may be about 3000 mm long.

As soon as the glazing bead 11 in the molding machine 1 is completely separated from the wood scant 2 by the glazing bead saw 10, the gripper unit 31 continues along the rail 33 in the X direction until the glazing bead 11 has completely emerged from the molding machine 1. Subsequently, the carrier 36 is moved with the clamping elements 37, 38 in the Z direction by a predetermined amount in a transfer position. In this transfer position, the glass strip 11 is taken over by the gripper unit 32. This gripper unit is arranged so that it lies in the region between the gripper unit 31 and the molding machine 1 directly next to the gripper unit 31. In this transfer position, the gripper unit 32 can bring by appropriate method in the X, Y and Z directions. Fig. 7 shows this transfer position, in which the two gripper units 31, 32 are arranged close to each other. The gripper unit 32 is initially in the X direction, then in the Y direction and finally in the Z direction. In this case, the gripper unit 32 is positioned so that the clamping elements 53, 54, 89 can receive the glass strip 11 immediately adjacent to the clamping elements 37, 38 of the gripper unit 31. This is the case with a first processing possibility, if the glass strip on both sides mitred and with exact finished length is processed. This processing case will be described below. With the clamping elements 53, 54, 89 is then in Fig. 7 clamped to the right of the gripper unit 31 lying part of the glass strip 11. In this transfer position, the glass strip 11 is thus clamped over a short period of time simultaneously by the clamping elements 37, 38 and 53, 54, 89 of the two gripper units 31, 32.

As soon as the gripper unit 32 has clamped the glass strip 11 in the transfer position, the clamping is released by the gripper unit 31. Subsequently, the gripper unit 32 is moved in the Y direction by moving the carriage 44 to the front, so that the glass strip 11 comes out of the clamping elements 37, 38 of the gripper unit 31. Subsequently, the carrier 52 of the gripper unit 32 with the clamped glass strip 11 in the Z direction can be moved upward on the gripper unit 31 and in the Y direction to the rear so far that the gripper unit 31 can drive back to the outlet 28 of the molding machine 1 ,

The gripper unit 32 is moved on to transport the clamped glass strip 31 to the miter saws 57, 58. During miter sawing, the gripper unit 31 can pick up the next glazing bead 11 and bring it to the transfer position in the manner described.

With the gripper unit 32, the glass strip 11 is first transported in the direction of the left miter saw 57 in the X direction. The clamping stations 63, 84 are open. In the area of these clamping stations, a sensor (not shown) is provided with which the front end of the glass strip 11, which is in the transport direction, is detected. The sensor gives a corresponding signal, whereby the exact axial position of the glazing bead in the plant and with respect the gripper unit 32 is known to position the glazing bead 11 by means of the gripper unit 32. After positioning, the glazing bar is clamped in the clamping station 63. For this purpose, the clamping element 64 of the clamping station 63 are pressed laterally and the clamping element 71 from above against the glass strip 11. In the area after the clamping station 63, the miter cut is performed.

During miter cutting or after clamping the glass strip 11 in the clamping station 63, the clamping of the gripper unit 32 is depressurized. As a result, between the clamping elements 53, 54, 89 and the glass strip 11 forms a small air gap, which is for example only about 1/10 to 3/10 mm. The gripper unit 32 travels in the X direction in the direction of the right end of the glass strip 11. At a distance (for example about 120 to 150 mm) from this end, the gripper unit 32 clamps the glass strip 11. The clamping in the area of the clamping station 63 can now be released. The gripper unit 32 transports the clamped glass strip 11 in the X direction to the right miter saw 58 in order to perform a miter cut with it on the right side of the glass strip 11. Since the clamping takes place at a small distance from the right end of the glazing bead, the gripper unit 32 can accurately insert the glazing bead 11 in the X direction into the two clamping stations 69 in front of and behind the miter saw 58. The clamping elements 70, 72 of the clamping stations 69 clamp the glass strip 11 laterally and from above. The miter cut is made between the two clamping stations 69. The glass strip 11 is replaced by the exact part length.

As long as the glass strip 11 is clamped in the clamping stations 69, the clamping of the gripper unit 32 is depressurized, so that the described small air gap between the clamping elements 53, 54, 89 and the glass strip 11 is formed. As a result, the gripper unit 32 can travel back along the glass strip 11 to approximately half of its length. There then clamp the clamping elements 53, 54, 89, the glass strip 11. After the miter cut the clamping of the clamping stations 69 is released. The gripper unit 32 is then moved so far in the X direction that the glass strip 11 is released from the clamping stations 69. Then, the glass strip 11 can be stored with the gripper unit 32 in one of the storage compartments 56 of the clipboard 30 controlled. The gripper unit 32 can retract with its lower clamping element 54 in the intermediate region between adjacent storage compartments 56, so that the glass strips 11 can be stored reliably. Since the glazing beads 11 have been picked up by the gripper unit 32 at half the length, they lie in the clipboard 30 in such a way that they bridge the gap between adjacent, axially aligned storage compartments 56.

When the clamping stations 69 are opened, the remnant 82 left after the miter saw drops down over a channel into a waste bin (not shown).

The clipboard 30 has a defined number of trays 56 whose position is recorded in a controller. Therefore, the location of each glazing bar 11 in the clipboard 30 is accurately determined.

The stored in the clipboard 30 glazing beads 11 are then pushed in the manner described with the slider 73 in the receptacles 75 of the fan tray 74. The clipboard 30 is moved in the Z direction so that the glazing beads 11 can be pushed into the desired plane of the receptacles 75. With the slider 73, the glazing beads 11 are inserted so that they, as in Fig. 3 represented, still slightly protruding from the receptacles 75. As a result, the glazing beads can be easily removed from the corresponding receptacles 75 during the production of the window sashes. The position of the individual glazing beads 11 in the compartment trolley 74 is detected by the control, so that the matching wooden edges 2 and glazing beads 11 are used in the production of window casements.

There are window sashes, which are subdivided by, for example, a rung extending between opposite sides of the sash. As a result, two glazing beads are required for these casement sides, which extend from the rung to the adjacent casement side. With the described system it is possible to divide the glass strip 11 into two glazing beads. The glass strip 1 is first clamped in the manner described on leaving the outlet 28 of the molding machine 1 by the gripper unit 31. The gripper unit 31 is first moved in synchronism with the feed of the molding machine 1 in the X direction and then completely pulled out of the molding machine 1. Subsequently, the gripper unit 31 is moved in the Z direction up to the transfer position. The gripper unit 32 moves in the X direction along the rail 44, which is then moved in the Y direction on the cross members 45, 46 so far that the gripper unit 32 is adjacent to the gripper unit 31. Subsequently, the carrier 52 is moved so far in the Z direction that the glass strip 11 can be clamped with the gripper unit 32. With the clamping element 89, the glass strip 11 against the upward contact surface 83 (FIG. Fig. 9 ) of the clamping element 54. The upper clamping element 53 of the gripper unit 32 clamps the glass strip 11 from above.

Immediately thereafter, the clamping of the gripper unit 32 is depressurized. This results in a small air gap of about 1/10 to 3/10 mm between the clamping elements 53, 54, 89 and the glass strip 11, which is fixed on four sides between the clamping elements 53, 54, 89 and the contact surface 83. The upper terminal strip 53, the lateral terminal block 89, the lower terminal block 54 and the contact surface 83 form a channel in which the glass strip 11 properly aligned, but a method of gripper unit in the X direction is possible.

The gripper unit is now moved in the X direction along the glazing bead 11 into a position in which the glazing bar is cut into two glass glazing parts with the left miter saw 57 and at the same time the required miter cut can be made on the right glazing bead part. That is, in the axial clamping position, the length of the left section with considered. Once this position is reached, the glass strip 11 is clamped by the gripper unit 32. Now, the clamping can be canceled by the gripper unit 31. As described above, the gripper unit 32 is moved so that the gripper unit 31 along the rail 44 in the direction of the outlet 28 of the molding machine 1 can be moved to take over the next glazing bead 11 there.

The gripper unit 32 is then moved in the manner described to the left miter saw 57, so that the glass strip 11 clamped by it passes in the process in the X direction in the clamping stations 63, 84 located on the left miter saw 57. The arranged in the region of the terminal stations sensor detects the left end of the glass strip 11. Now, the glass strip 11 defined in the X direction can be moved so far that with the miter saw 57, the first miter cut can be performed. Through him, the glass strip 11 is divided into two parts, with the miter cut of the resulting right glass bead part is now mitred at its left end. During the miter cut, the glazing bead 11 is clamped in the clamping stations 63, 84 so that a clean miter cut can be made.

As long as the glass strip 11 is clamped in the clamping stations 63, 84, the clamping of the gripper unit 32 is depressurized, resulting in the small air gap of about 1/10 to 3/10 mm between the clamping elements and the glass strip. The gripper unit 32 can now be moved along the right glass bead part in the X direction so far that the clamping elements as described have a defined distance from the right end of the right glass bead part. Now this right glass bead part is stretched by the gripper unit 32 and lifted the clamping in the clamping station 63. The left section remains tensioned in the clamping station 84.

The gripper unit 32 can now transport the right glazing bead part to the right miter saw 58 in the X direction. The clamping stations 69 are open. After clamping by the clamping stations 69, the right miter cut is made on this right glass bead part. He has thus, since at both its ends with the two miter saws 57, 58, the miter cuts have been executed, its exact part length.

After execution of the miter cut, the clamping of the gripper unit 32 is depressurized so that it can be moved along the right glass bead part so far in the X direction until it is about halfway along this right glass bead part. Now this right glass bead part can be tensioned by the gripper unit 32. Then, the clamping of the right Glasleistenteiles is removed in the clamping stations 69 by the clamping elements 70, 72 are moved away laterally and upwards. With the gripper unit 32 now the right glass bead part can be stored in the manner described in the clipboard 30.

The remaining part of the miter cut at the miter saw 58 falls over the channel described in the waste container.

The left glass bead part is still clamped in the provided behind the left miter saw 57 clamping station 84 (FIG. Fig. 9 ). Their two clamping elements 85, 86 clamp the left glazing bead part from above and from the left side. The entire clamping station 84 is movable in the direction of arrow 87 in the Y direction. In order for the left glazing bead part clamped in the clamping station 84 to be taken over by the gripper unit 32, the clamping station 84 is moved so far in the direction of the arrow 87 that the left glazing bead part gets a sufficient distance from the miter saw 57. Then the clamping elements 53, 54, 89 of the gripper unit 32 can take over the left glazing bead part. With the gripper unit 32, this left glazing bead part is transported to the miter saws 57, 58 to make the miter cuts at both ends.

With the system described, it is possible that the glass strip 11 is provided only at one end with a miter cut. Do you want the miter? the left side of the glass strip 11 are made, the process is identical to the previously described process with miter cuts on both sides. After the transfer of the glass strip 11 in the manner described by the gripper unit 31 to the gripper unit 32, the glass strip is transported in the X direction by the gripper unit 32 until the sensor in the region of the left miter saw 57 detects the last beginning, whereby the exact axial Position in the plant is known. Since the glass strip is always clamped either in one of the clamping units or the gripper unit 32 in the further operations, the position position is no longer lost. As a result, the glass strip can always be exactly positioned over the X axis of the gripper unit 32 during further processing and handling. The glass strip is then clamped in the clamping station 63 and performed with the miter saw 57 at the left end of the glass strip 11 of the miter cut. In this case, or subsequently, the clamping of the gripper unit 32 is depressurized, so that the gripper unit 32 can be moved approximately in half the length of the glass strip 11. There, the glass strip 11 is clamped and stored by means of the gripper unit 32 in the clipboard 30.

If the miter to be made on the right side of the glass strip 11, the process is also identical to the previously described process with miter cuts on both sides with the difference that at the left end no miter cut is performed. Since the optical sensor for accurate position detection is provided only on the left miter saw, this process is necessary. If the right-hand miter saw also has an optical sensor that then detects the right-hand beginning of the glass strip, the glass strip can also be fed immediately to the right-hand miter saw. The transfer of the gripper unit 31 to the gripper unit 32 is then carried out so that the gripper unit 32 receives the glass strip in the X direction near the right end and clamps. The further procedure is as described. Depending on the desire and further handling, the one-sided mitred glass strips are stored in the clipboard 30 or placed in the Rohleistenwagen 81.

Finally, it is possible to use the glass strip 11 without miter cuts. In this case, the glass strip 11 is detected in the manner described at the outlet 28 of the molding machine 1 by the gripper unit 31 and transported to the transfer position, in which the glass strip 11 is transferred in the manner described to the gripper unit 32. It transports the glass strip 11 into the area above the chute 80 (FIG. Fig. 2 ). The clamping elements of the gripper unit 32 are then opened, so that the glass strip 11 passes through the chute 80 in the Rohleistenwagen 81.

Such glazing beads are not necessarily profiled in the moulder, but only planed, for example. You fall for example, if from the wooden shells 2 no window sash, but window frames are to be made. For window frames, glazing beads are not required. These pre-machined glass strips can be finished in a later processing step and used for the production of window sashes.

With the system described, it is possible already inside the molding machine 1 finished profiled glazing beads 11 to separate out of the processed in the molding machine wooden shells 2, so that at the outlet 28 of the molding machine 1 already separate glazing beads 11 and wooden shells 2 are available. The glazing beads 11 are transported by means of the described gripper devices 31, 32 to the left and / or the right miter saw 57, 58, depending on the further processing task, on which the respective miter cut is made on the glazing bead 11. In the area of each miter saw 57, 58 clamping stations are provided in front of and behind the saw, so that the glass strip 11 is clamped or clamped properly during the miter cut. This allows the miter cut to be made accurately. With the gripper unit 32, the glass strip 11 is always accurately introduced into the clamping stations by the gripper unit 32 is positioned in the region of that end at which the miter cut is to be performed. Especially with long glazing beads 11 is thereby ensuring that the end to be mitered is fed exactly to the clamping stations. Since the unpressurized jaws form the channel described, in which the glass strip has little play, the gripper unit 32 can be moved along the glass strip in the different positions with respect to the glass strip 11, whereby it is achieved that the glass strip, especially if it is longer is held straight or straightened so that a reliable clamping, processing and safe transport of the glass strip 11 is guaranteed in the system. The system thus makes it possible to profile glass strips in a moulder on the longitudinal sides in a fully automated process sequence and to cut them out of a wooden skirt and, if required, to execute the miter cuts using downstream manipulation and processing devices so that the glass strip is ready for installation ,

The transfer always takes place in such a way that the gripper unit 32 first moves directly next to the gripper unit 31 and clamps the glass strip. If the glass strip 11 must be detected at a different location, the gripper unit 31 is depressurized and then moved in the X direction. Since the glazing beads 11 can sag outside of the clamping and can also be rotated by residual stresses, it is not possible to grasp the gripper unit 32 at a distance from the gripper unit 31.

Instead of the gripper units 31, 32, other manipulators can also be used, for example robots. Depending on the required throughput or required quantity of power, only one gripper unit 32 or robot can be used, which removes the glazing beads both of the molding machine and supplies it to the glass bead saws.

In a further embodiment, two gripper units 31 are provided one behind the other in the X direction, of which the first clamps the glazing bead 11 on leaving the moulder 1 as described at the outlet end after the speed has been synchronized. The second gripper unit, which is provided in the direction of passage between the first and the outlet side of the molding machine, stops until the glass strip 11 is almost severed, then synchronized with the feed rate and then clamps the glass strip on the outlet side rear, so right end. This ensures that the glass strip 11 is optimally held at the time of complete separation.
