Description

Apparatus for producing and/or processing glass strips and methods of using the same

The present invention relates to an apparatus for producing and/or processing a glass strip as described in the first paragraph of the patent application, and a method of using such a device as claimed in claim 20 of the patent application.

In the manufacture of sashes, the workpiece consisting of pretreated wood strips and a number of associated glass strip edges are shaped. First, in the first process, the wood strip (workpiece) is pre-shaped in the slotting machine, and wherein the unprocessed or partially shaped glass strip edge is separated from the subsequent window slot of the window frame or sash . In other processes, the sash member is finally shaped and machined, and the glass strip is finally shaped and chamfered to the correct length. However, such a scheme is more cumbersome.

It is an object of the present invention to design a device of the same type and a method of the same type in a manner such that the glass strip is simply fabricated from the workpiece, separated and further processed.

In terms of equipment of the same type, the solution of the present invention for achieving the above object is the feature of claim 1 of the patent application, and the invention is used in the same type of method. The solution to achieve the above objectives is the feature of claim 20 of the scope of patent application.

The apparatus of the present invention has the processing machine provided with a plurality of tools for completely shaping the longitudinal sides of the glass strips as the workpiece passes through the processing machine. At least two tools are adapted to separate the final shaped glass strip from the workpiece. Subsequent processing of the longitudinal sides of the glass strips is then no longer necessary. Thus, the shaped or pre-shaped workpiece and the shaped glass strip edge are removed from the processing machine as separate components.

The processing machine is preferably a slot machine capable of processing all four sides of the workpiece during the passage. Wherein, the glass strip edge is also separated from the workpiece.

Preferably, a tool is provided on the horizontal spindle, the tool being located in the region above the workpiece in the conveying path of the workpiece through the processing machine. By means of this tool, a first slit can be created on the top surface during the passage of the workpiece, whereby the glass strip edge is partially separated from the workpiece.

Depending on the direction of travel of the workpiece through the processing machine, the tool is preferably provided after the tool, preferably having a rotational axis that is inclined relative to the direction of transport of the workpiece. The two tools are preferably spaced a certain distance back and forth along the conveying direction of the workpiece, so that the desired slit can be smoothly and accurately produced in the workpiece.

The other tool having an inclined axis of rotation preferably consists of a saw blade and a frustoconical cutter. This tool constitutes a chisel that can machine the underside of the glass strip. The desired separation slit is created in the workpiece by the disc saw blade to separate the glass strip edges.

Preferably, a split wedge or split wedge shaped support is disposed downstream of the other tool.

The separated glass strip edge and the remaining portion of the workpiece are preferably simultaneously The discharge port of the processing machine is removed. Preferably, only the side of the glass strip is gripped and further processed while the remainder of the workpiece is further conveyed through a conveyor for further processing.

According to a further embodiment of the device according to the invention, at least one storage device is arranged downstream of the processing machine. The storage device is provided with at least one, preferably two, gripping units for removing the glass strips from the processing machine and storing them on at least one storage rack.

According to a preferred embodiment, one of the gripping units is a 2-axis gripping unit for transporting the side of the glass strip in two mutually perpendicular directions. The gripping unit preferably receives the final shaped glass strip removed from the processing machine.

Preferably, the other gripping unit is a 3-axis gripping unit for transporting the side of the glass strip in three mutually perpendicular directions.

According to a preferred embodiment, the two gripping units can be adjusted to a transfer position in which one of the gripping units transmits the glass strip edge to the other gripping unit. Upon removal of the strip from the processing machine, one of the gripping units receives the strip of glass and transports it to the transfer position. The second gripping unit receives the glass strip edge. Once the transfer is complete, the first grip unit can be moved back to the processing machine to receive the next glass strip edge. During this time, the glass strip can be conveyed to another processing and/or processing system by the second gripping unit.

Preferably, one of the gripping units grips the edge of the glass strip at the discharge opening of the processing machine and delivers it to the transfer position. In the case where the edge of the glass strip has not been completely separated from the workpiece, the travel speed of the first gripping unit is synchronized with the feed speed of the glass strip in the processing machine. Once the glass strip is completely separated and as appropriate The gripping unit is completely pulled out of the processing machine, and the gripping unit can immediately transport the strip side to the transfer position in a manner independent of the feed rate of the processing machine.

According to a preferred embodiment, the device is provided with at least one miter saw for performing beveling on the side of the glass strip if necessary. "Missing saw" also refers to a chisel used to machine a bevel on the edge of the glass strip.

Preferably, the apparatus has a left miter saw and a right miter saw for performing a left chamfer and a right chamfer on the side of the glass strip by the miter saw.

According to a preferred embodiment, in order to achieve a neat chamfer, a clamping station is provided in front of each miter saw of the device. The glass strips are clamped in the clamping stations for chamfering. Since the glass strip is clamped in the two clamping stations, a neat and precise beveling can be achieved.

Preferably, the second gripping unit for transporting the strip of glass to the miter saw and the corresponding clamping station enters a pressureless state. In this way, a small air gap is created between the clamping element of the second gripping unit and the edge of the glass strip. Therefore, in the case where the glass strip is clamped in the clamping station of the miter saw, the second gripping unit can be moved along the X-direction of the glass strip. Therefore, for example, during the beveling by the left miter saw, the second gripping unit can be moved along the edge of the glass strip toward the right end of the glass strip edge, thereby clamping the glass strip edge by the second gripping unit. In this end region, the glass strip edge is conveyed to the right miter saw after the beveling by the left miter saw. Since the glass strip side is clamped by the second gripping unit in proximity to the right end of the glass strip side, the glass strip side can be accurately inserted into the clamping station located before and behind the right miter saw.

Preferably, the storage device is provided with a plurality of storage compartments for the sides of the glass strips for storing the glass strips in an orderly and precise manner.

These storage compartments are height adjustable in the Z direction.

The apparatus is preferably provided with at least one pusher for moving the edges of the glass strips in the storage compartments into a plurality of receiving openings.

The accommodating ports are preferably overlapped and arranged side by side to accommodate a large number of glass strip edges in a small space. The storage compartments are height-adjustable so that the glass strips can be smoothly pushed into the overlapping openings.

The accommodating ports are preferably disposed on a transport vehicle, and the transport vehicles can be removed after the accommodating ports are filled to further utilize the glass strip edges, for example, for manufacturing sashes.

When the method of the present invention is used, the gripper unit grips the edge of the glass strip removed from the discharge port of the processing machine. At this point in time, the glass strip edge has not been completely separated from the workpiece. Therefore, the gripping unit is synchronized with the feed rate of the processing machine before the end of the glass strip is gripped.

Once the strip edge is completely separated from the workpiece and optionally pulled by the gripping unit from the processing machine, the strip side is immediately conveyed by the gripping unit to the processing unit for processing the strip side.

The processing units are preferably miter saws or chisels for beveling the glass strips to a final length.

According to a preferred method, the gripping unit conveys the edge of the glass strip to a miter saw. Before the miter saw, the glass strip edge is clamped or clamped before and after the miter saw, if necessary, in order to carry out a neat chamfer. During the implementation of this beveling operation, the clamping of the gripping unit enters a no-pressure state. In this way, a small air gap is produced between the clamping element of the gripping unit and the edge of the glass strip. Thereby, the gripping unit can be moved along the side of the glass strip to another glass The end of the strip moves. The gripping unit can re-clamp the glass strip edge at a distance from the end of the glass strip edge, so that after performing one of the chamfering, the glass strip side is conveyed to the opposite miter saw so that A bevel is performed on the other end.

After the desired chamfering has been carried out, preferably in the case of clamping into a pressureless state, the gripping unit is moved along the edge of the glass strip to about half the length of the side of the glass strip. At this point, the glass strip is clamped by means of the gripping unit. The clamping before the miter saw can then be released. The glass strip can then be stored in the storage compartment by the gripping unit.

According to a preferred embodiment, the glass strip is conveyed to a transfer position by the gripping unit. The glass strip edge is transferred to the other gripping unit in the transfer position.

The subject matter of the present application is also given by the disclosure of all the disclosures and features of the disclosure. Information and features that are novel in nature, either individually or in combination, with respect to the prior art, even if they are not the subject of the patent application, are inventive features.

The invention will now be further described with reference to the embodiments shown in the drawings.

By means of the device, the strips are sawed from the workpiece (hereinafter referred to as wood strips) and the strips are pre-machined for further processing of the sash parts or sash parts. To this end, the apparatus has a processing machine 1, which is preferably a slotting machine. In the processing machine, the strips are processed during the passage and the strips are separated from the strips. The basic structure of the slotting machine is shown in FIG. The grooving machine has a table on which the wood strip 2 is conveyed through a number of conveying elements, preferably feed rollers, through the machine. The feed rollers abut against the top surface of the wood strip 2 under pressure and transport the wood strips through the machine. The feed zone of the grooving machine has a horizontal lower spindle 3 on which a tool for processing the underside of the wood strip 2 is provided. In the conveying direction 4, the slotting machine has a vertical right spindle 5 located behind the lower spindle 3, on which is provided a tool for machining the right longitudinal side of the strip 2 in the conveying direction. In the conveying direction 4, the slotting machine has a left spindle 6 located behind the lower spindle 3, carrying a tool for machining the left longitudinal side of the strip 2 in the conveying direction.

Downstream of the left spindle 6, there are two horizontal upper spindles 7 and 8 spaced apart by a distance, carrying tools for machining the top surface of the wood strip 2.

In the conveying direction 4, the slotting machine is provided with a horizontal lower spindle 9 arranged at a distance from the upper spindle 8, by means of which the tool of the lower spindle can machine the underside of the strip 2. Finally, the grooving machine is provided with a glass edge saw 10 for separating the glass strip edges from the wood strip 2, the separation mode will be explained below. The rotating shaft of the glass strip saw 10 is inclined with respect to a vertical line.

Figures 13 to 15 show the strip 2 from the discharge side of the slotting machine 1, and the operation of separating the strip side 11 from the strip 2 will be described in connection with these figures. During the passage, all four sides are machined by the slotting machine 1 in a conventional manner. The right longitudinal side of the strip 2 is machined by means of a tool 12 which is arranged on the right spindle 5 and rotatable about the axis 13. In this case, for example, the right longitudinal side 14 is machined in such a way as to retain the protruding side 15 near the top surface. Once the strip 2 enters the working area of the horizontal upper spindle 8, the longitudinal direction along the strip 2 is achieved on the top surface 18 by means of a tool 16 provided on the upper spindle that is rotatable about an axis perpendicular to the conveying direction 4. Extended cut or shape. The tool 16 is of a design or styling scheme such that the glass strip edge 11 to be separated has a desired outer contour in this area. The shaping operation can also be assigned to the two spindles 7, 8 depending on the specific situation. For example, the sawing marks can be carried out by the upper spindle 7, and the saw marks can be reshaped by the spindle 8. In the area of the upper main shaft, the wood is still very dense, so Excellent surface quality for this final styling operation. The side surface processed by the upper tool is the visible surface after the glass strip 11 is loaded. At present, the method for separating the edge of the blank glass strip is to perform horizontal sawing on the right main shaft according to the width of the edge of the blank glass strip, and on the upper main shaft, or by using a separate glass strip saw from above. The edges are separated. With this treatment, high-quality machining cannot be performed by the upper tool because the horizontal saw marks provided in advance cause the strip edges to no longer be sufficiently stably connected to the wood strip. Therefore, during processing, the edges of the glass strip may vibrate due to excitation.

During the further passage of the strip 2 through the slotting machine, the glass strip edge 11 is completely separated from the strip 2 by the glass strip saw 10. For example, the axis of rotation 19 of the glass strip saw 10 is at an angle of about 65° with respect to the vertical. The glass strip saw 10 and the tool provided thereon are of a design in order to machine the glass strip 11 on the bottom surface and at the same time completely separate the glass strip from the strip 2, wherein the strip side 11 obtains the desired The final shape. The glass strip saw 10 can be constructed in different ways, depending on the design of the glass strip 11 . In the present embodiment, the glass strip saw is composed of a saw blade 10a and a truncated cone cutter 10b (which may be, for example, a chisel).

Figures 13 and 14 show, in broken lines, the final shape of the glass strip 11 after separating the glass strip edges 11. Figure 15 shows an exemplary final shape of the wood strip 2 in dashed lines. As shown in Fig. 15, the glass strip saw 10 is designed to be spaced apart from the final shape 20 of the strip 2. Therefore, when the final shape is produced on the right longitudinal side of the strip 2 using the corresponding tool, there is still sufficient material available. This is preferably achieved by performing a split cut in a manner that is inclined relative to the horizontal plane. This solution can be achieved where the axis of rotation 19 is at an angle relative to the vertical line as described above.

During the single pass of the strip 2, the slotting machine can be used to The desired longitudinally shaped glass strip edge 11 is separated from the wood strip 2. Thereby, the glass strip edge 11 can be manufactured at low cost.

Figure 16 exemplarily shows how the sash can be made using the remaining parts of the strip 2 separated by the strip 3, the final processed part in another processing step, and the strip side 11. Figure 16 shows a portion of the lower frame member of the sash containing the components of the wood strip 2, which bears against the edge of the glazing 21. The edge region of the glazing is supported on the support surface 22 of the slat. On the opposite side, the glazing 21 is held through the glass strip 11 which is snapped into the recess 23 of the strip 2 by the projecting side edges 15. With this coverage, the length tolerances of the glass strips and sashes can be compensated without the need to implement this compensation in a visible manner. Here, there is a strip of glass that is turned over.

The glazing 21 is sealed by two seals 24, 25 which are disposed between the strip 2 and the glass strip 11. In order to form a receiving cavity corresponding to the seals 24, 25, corresponding bevels 26, 27 are provided on the side of the strip 2 and the glass strip 11 facing the window pane 21. The inclined surface 27 of the glass strip 11 is a surface which is generated by a rotating shaft having a certain angle when the glass strip saw 10 is subjected to the separating operation.

Since the glass strip edge 11 is separated from the wood strip 2 in the manner described in the slotting machine 1, the final shaped glass strip edge 11 and the remainder of the pre-formed wood strip 2 are from the discharge opening 28 of the slotting machine 1 ( Figure 1) Removed. The strip 2 reaches a conveying device 29 which is preferably an endless conveyor belt. The strip 2 is conveyed by this conveyor to other processing systems or, for example, to a collection point (not shown) in which the strip 2 is intermediately stored for further use.

The grip unit 32 has a slider 43 that is movable along the track 44 in the X direction. The track is placed on the lateral supports 45, 46 extending in the Y direction by both ends so that the tracks 44 can be moved along the Y direction along the supports. The transverse brackets 45, 46 are placed on the upper ends of the columns 47, 50 which are supported on the ground. The lateral brackets 45, 46 and the columns 47 and 51 are all part of the frame. A rail 33 is fixed to the two columns 49, 50 so that the grip unit 31 can travel along the X direction along the rail. The rails 33 are located below the lateral brackets 45, 46 at a distance from each other to prevent the gripping unit 31 from colliding with the lateral brackets during the X-direction.

In order to move the slider 43 along the rail 44, a driver 51 is provided. On the slider 43, a vertical bracket 52 is provided in such a manner as to be movable in the Z direction, the end of which carries two clamping members 53, 54. The lower clamping element 54 is embodied as a support strip against which the glass strip edge 11 in the clamping position rests On the support strip. The support strip 54 also has a vertically extending abutment surface 83 (Fig. 9) against which the glass strip edge 11 in the clamped position abuts. The upper clamping element 53 can be adjusted in the Z direction by the drive unit 55. The design of the drive unit 55 equipped with the guide is similar to the drive unit 41 equipped with the guide 40.

The grip unit 32 is provided with a further clamping element 89 which is arranged on the swivel arm 90. The swivel arm employs a mounting arrangement that is rotatable about a horizontal axis X extending in the X direction. In the region between the rotary shaft 91 and the clamping element 89, the piston rod 92 of the drive unit 93 is snapped onto the swivel arm 90, which is mounted in a manner that is rotatable about a horizontal, X-direction axis 95. The free end of the support arm 94. The support arm 94 extends laterally beyond the bracket 52 to which it is secured. The glass strip edge 11 can be clamped on the left side by means of the clamping element 89. All of the clamping elements 53, 54, 89 are located at substantially the same height relative to the clamped glass strip side 11.

The grip unit 32 is capable of moving along the track 44 in the X direction. The track 44 itself can be moved in the Y direction along the lateral brackets 45, 46 which are parallel to each other. The bracket 52 containing the clamping elements 53, 54, 89 is capable of moving in the Z direction.

An intermediate storage rack 30 is provided in the area between the columns 47 to 50 for intermediate storage or storage of the glass strip edges 11. The intermediate storage rack 30 is height adjustable in the Z direction. To this end, the intermediate storage rack 30 can be mounted on two or more of the columns 47 to 50, for example, in a height adjustable manner.

As shown in Figure 11, the intermediate storage rack 30 has a plurality of storage compartments 56 extending in the X direction for storing the glass strip edges 11. The storage compartment 56 can be formed, for example, by a sheet of corresponding shape. In order for the gripping unit 32 to reliably store the glass strip edges 11 in the storage compartment 56, the adjacent storage compartments along the X-direction are spaced apart from each other by a certain distance. In this region, the clamping elements 53, 54 are included, The gripping unit 32 of 89 can be moved in to store the glass strip edge 11.

In the region of the transverse bracket 45, a left miter saw 57 or machining unit is provided on the post 50, and relatively, in the region of the transverse bracket 46, a right miter saw 58 is provided on the post 49. By means of the two miter saws 57, 58, a bevel can be performed on the end of the glass strip 11 as needed. The left miter saw 57 (Fig. 9) has a circular chisel 59 that is rotatable about an axis that is inclined relative to the X direction for tilting the ends of the glass strips 11. The advantage of replacing the circular saw blade with a chisel 59 is that no debris is generated when the bevel is implemented. The chisel 59 is located in the shield 60. A circular chisel 59 is placed on the shaft driven by the drive unit 91. The drive unit 61 is fixed to a bracket 62 that is held on the lateral bracket 45.

In the region in front of the miter saw 57, a clamping station 63 is provided which has a clamping element 64 which is adjustable in the Y direction and a clamping element 71 which is from top to bottom. Depending on the conveying direction 4 of the strip 2 passing through the slotting machine 1, the clamping station 63 containing the clamping elements 64, 71 is located to the left of the side of the glass strip and is located in front of the miter saw 57. After the miter saw 57 a further clamping station 84 is provided which has two clamping elements 85, 86. The glass strip edge 11 is clamped on the left side by the clamping element 85. The clamping element 86 snaps onto the glass strip 11 and clamps it from top to bottom.

The right miter saw 58 (Fig. 10) has a drive unit 65 for rotationally driving the saw blade 66. The saw blade 66 is located below the shield 67. The drive unit 65 is mounted on a bracket 68 that is fixed to the post 49. The axis of rotation of the miter saw 58 is also inclined relative to the X direction, but is inclined relative to the axis of the left miter saw 57.

Also in the region in front of and behind the miter saw 58 are clamping stations 69 each having at least one clamping element 70 which is adjustable in the Y direction for lateral clamping of the glass strip 11 . With the clamping element, the side of the glass strip is both in front of the saw and behind the saw Clamping. By means of the clamping element 72, the glass strip edge 11 is clamped from top to bottom before the miter saw 58. The clamping stations of the miter saws 57, 58 are suitably arranged in a manner fixed to the apparatus. For the sake of clarity, Figures 9 and 10 do not fully show the support scheme for the clamping stations 63,69.

The glass strip side 11 stored on the intermediate storage shelf 30 is fed to the compartment truck 74 by means of a pusher 73 (Fig. 3) having a plurality of overlapping and side-by-side tubular receiving openings 75 for the glass strip side 11. The pusher 73 adopts a design scheme so as to be able to snap into the storage compartment 56 or abut against the storage compartment to reliably move the edge of the glass strip located in the storage compartment into the receiving compartment of the compartmental vehicle 74. 75. The number of storage compartments 56 in the Y-direction on the intermediate storage rack 30 is the same as the number of receptacles 75 on one of the compartments 71. As exemplarily shown in FIG. 3, the glass strip side 11 located in the intermediate storage rack 30 is simultaneously pushed into the receiving opening 75 of the compartment car 74 by the pusher 73. The pusher 73 extends in the Y direction and is movable by both ends along the rails 76, 77 extending in the X direction. For example, the pusher 73 can be driven in some manner by a drive belt 78 located on either side of the rails 66, 67 such that the pusher 73 moves in the direction of the arrow 79 (Fig. 3) to push the strip side 11 into the receiving opening. 75, and moving the pusher in the opposite direction. The intermediate storage rack 30 is height-adjustable in the Z-direction so that the intermediate storage rack can be positioned relative to the compartment car 74 to fill the glass strip edge 11 for each layer of the compartment car 74.

The compartment 74 is movable, so that the compartment can be removed in order to remove the glass strip 11 from the compartment for further use. The compartment car 74 is moved to the intermediate storage frame 30 in a manner between the columns 47, 50 (Fig. 1), and the compartment car is fixed as appropriate, thereby smoothly positioning the glass strip 11 from the storage compartment 56. Move into the receiving port 75.

On the bottom surface of the storage unit having the intermediate storage layer 30, which faces away from the miter saws 57, 58, a slide 80 (Fig. 2) is provided. For the sake of clarity, the slide is not shown in Fig. 1. The slide The columns 47, 48 extend obliquely rearwardly and downwardly, and are used to feed the blank glass strips accumulated during processing into the blank strip car 81. The rough strip side car 81 can also be moved.

In the slotting machine 1, the four sides of the strip 2 are machined in the manner described, and the strip side 11 is separated, and the glass strip is finally shaped. The shaped wooden strip 2 and the shaped glass strip edge 11 are removed from the discharge opening 28 of the slotting machine. The glass strips 11 are conveyed by the two gripping units 31, 32 to the miter saws 57, 58 (see below for specific ways), so that the chamfering is carried out if necessary. The sawn glass edge 11 is then stored on the intermediate storage shelf 30 in a predetermined manner. The glass strip 11 is then pushed into the receiving opening 75 of the compartment car 74 by the pusher 73.

Subsequently, as shown in Fig. 16, the glass strip edge 11 is joined to the wood strip 2 which has been shaped in the slotting machine 1 to form a window sash. Therefore, the glass strip edge 11 and the wood strip 2 separating the glass strip edges are stored in a predetermined manner. In order to subsequently join the sash, the glass strip 11 is rejoined with the corresponding strip 2 . This makes it possible to achieve a highly integrated form of the sash.

The glass strips can be smoothly matched to the wood strips through a computer-controlled storage solution. The miter saws 57, 58 may be arranged to be inclined at a fixed angle (preferably 45) with respect to the longitudinal axis of the glass strip edge 11. However, according to a preferred embodiment, the miter saws 57, 58 can be adjusted to different tilt positions. In this case, the miter saws 57, 58 are rotatable about a vertical axis. During the sawing process, the glass strip edge 11 is reliably clamped, so that a neat chamfer can be achieved.

During the passage of the strip 2 through the slotting machine 1, the strip side 11 is separated from the strip 2 by means of a tool 10 provided on the last spindle. The rotating shaft 19 of the glass strip saw 10 is arranged obliquely (Figs. 4, 5, 12 and 15). The glass strip saw 10 has a splitting wedge 96 disposed downstream of the passing direction, which constitutes an additional support member, whereby the glass strip 11 can be neatly trimmed from the strip 2 Separate and guide the edge of the glass strip. The pressing roller, not shown, immediately after the sawing of the glass strip, can press the glass strip 11 onto the support as needed, so that the end of the glass strip is at the point of time when the strip is completely separated from the strip. Being reliably guided and maintained.

The gripping unit 31 is positioned on the outlet 28 of the slotting machine 1 in such a way that the gripping elements 37, 38 of the gripping unit are able to snap the glass strip from above and below to clamp it.

Since the glass strip 1 and the wood strip 2 are fed out of the discharge port 28 through the conveying member of the slotting machine 1, the machine feed in the X direction is realized by the driver of the grip unit 31. For this purpose, a control system (not shown) is provided which synchronizes the conveying speed of the gripping unit 31 with the feed speed of the slotting machine. After the synchronization is achieved, the clamping elements 37, 38 are gripped by the press fit in a manner spaced apart from the front end of the glass strip 11 in the feed direction, in particular by the upper clamping element. Move down to clamp the glass strip from top to bottom. The distance from the front end of the glass strip is, for example, about 120 to 150 mm. The length of the shortest glass strip side is, for example, about 380 mm, and the length of the longest glass strip side is, for example, about 3000 mm.

Once the glass strip edge 11 is completely separated from the wood strip 2 by the glass strip saw 10 in the slot machine 1, the gripping unit 31 is further moved along the track 33 in the X direction until the glass strip side 11 is completely removed from the slot machine 1. Subsequently, the bracket 36 containing the clamping members 37, 38 is moved in the Z direction into a transfer position in accordance with a predetermined degree of travel. In this transfer position, the glass strip 11 is received by the grip unit 32. This gripping unit adopts the following arrangement: it abuts the gripping unit 31 in the region between the gripping unit 31 and the slotting machine 1. The gripping unit 32 can be fed into the transfer position by a corresponding movement in the X, Y and Z directions. Figure 7 shows this transfer position in which the two gripping units 31, 32 are closely arranged side by side. Grasping unit 32 first moves in the X direction, then in the Y direction, and finally in the Z direction. In this case, the gripping unit 32 is positioned in such a way that the gripping elements 53, 54, 89 receive the strip side 11 in the manner of the gripping elements 37, 38 of the gripping unit 31. The above operation is found in the first processing scheme, that is, the oblique processing is performed on both sides of the glass strip through a precise final length. This processing scheme is described below. The portion of the glass strip 11 on the right side of the grip unit 31 in Fig. 7 is clamped by the clamping members 53, 54, 89. Thus, in this transfer position, the clamping elements 37, 38 and 53, 54, 89 of the two gripping units 31, 32 simultaneously clamp the glass strip 11 in a short time.

Once the gripping unit 32 clamps the glass strip edge 11 in the transfer position, the clamping by the gripping unit 31 is released. The gripping unit 32 is then moved forward in the Y direction by the movement of the slider 44, thereby moving the glass strip edge 11 out of the gripping elements 37, 38 of the gripping unit 21. The bracket 52 holding the glass strip 11 of the gripping unit 32 can then be moved upward in the Z direction and moved back in the Y direction to a certain extent in order to move the gripping unit 31 back in a manner to be passed by the gripping unit 31. Return to the discharge port 28 of the slot machine 1.

The gripping unit 32 is moved further to convey the clamped glass strip edge 11 to the miter saws 57,58. During the miter saw, the grip unit 31 can receive the next glass strip edge 11 and deliver it to the transfer position in the manner described above.

By means of the gripping unit 32, the glass strip edge 11 is first conveyed along the X-direction to the left miter saw 57. The clamping stations 63, 84 are open. In the region of the clamping stations, a (not shown) sensor is provided for detecting the front end of the glass strip 11 in the conveying direction. The sensor emits a corresponding signal to provide a precise axial position of the strip of glass in the apparatus and relative to the gripping unit 32 to position the glass strip 11 by the gripping unit 32. After positioning, in the folder The glass strip side is clamped in the station 63. For this purpose, the clamping element 64 of the clamping station 63 is laterally oriented and the clamping element 71 is pressed from above towards the glass strip edge 11. The chamfering is carried out in the area behind the clamping station 63.

During the beveling process, or after the glass strip 11 is clamped in the clamping station 63, the clamping of the gripping unit 32 enters a no-pressure state. As a result, a small air gap is formed between the clamping elements 53 , 54 , 89 and the glass strip 11 , which is, for example, only approximately 1/10 to 3/10 mm. The grip unit 32 moves in the X direction toward the right end of the glass strip side 11. The grip unit 32 clamps the glass strip 11 in a manner spaced a distance from the end (e.g., about 120 to 150 mm). From this point on, the clamping in the region of the clamping station 63 can be released. The gripping unit 32 transports the clamped glass strip side 11 in the X direction to the right miter saw 58 so as to be chamfered on the right side of the glass strip side 11 by the right miter saw. Since the clamping is performed at a small distance from the right end of the glass strip, the gripping unit 32 can accurately feed the glass strip edge 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 station 69 clamp the glass strip side 11 from the side and from above. A chamfer is performed between the two clamping stations 69. The glass strip 11 thus has a precise part length.

Once the glass strip 11 is clamped in the clamping station 69, the clamping of the gripping unit 32 enters a pressureless state, thereby constituting the smaller portion described above between the clamping members 53, 54, 89 and the glass strip side 11. Air gap. Thus, the gripping unit 32 can be moved back along the glass strip 11 until about half the length of the glass strip edge is reached. Subsequently, the clamping elements 53, 54, 89 clamp the glass strip 11 there. After the chamfering is performed, the clamping of the clamping station 69 is released. In this case, the gripping unit 32 is caused to move a certain extent in the X direction such that the glass strip side 11 is removed from the clamping station 69. The glass strip 11 can then be stored in the storage compartment 56 of the intermediate storage bin 30 by means of the gripping unit 32 in a controlled manner. The gripping unit 32 can be moved into the adjacent storage by its lower clamping element 54 The intermediate portion between the cells is placed so that the glass strip 11 is reliably stored. Since the gripping unit 32 grips the glass strip edge 11 at half the length thereof, the glass strip edge in the intermediate storage rack 30 will span the gap between the axially aligned adjacent storage compartments 56.

In the case where the clamp station 69 is opened, the debris 82 accumulated after the miter saw operation is dropped into the waste container (not shown) through the passage.

The intermediate storage rack 30 has a number of storage compartments 56 that are stored in the control system. Therefore, the position of each of the glass strip edges 11 in the intermediate storage rack 30 is clear.

The glass strip 11 stored in the intermediate storage rack 30 is then pushed into the receiving opening 75 of the compartment car 74 by the pusher 73 in the manner described above. The intermediate storage rack 30 is moved in the Z direction in a manner to push the glass strip side 11 into the desired layer of the receiving opening 75. The glass strip 11 is pushed in by some means by the pusher 73 so that it protrudes slightly from the receptacle 75 as shown in FIG. Thereby, the glass strip edges can be conveniently taken out from the corresponding receiving openings 75 when the sash is manufactured. The position of each glass strip 11 in the compartment car 74 is detected by the control system so that the matching strip 2 and the glass strip 11 are used in the manufacture of the sash.

For example, some sashes are divided by a frame strip that extends between the sash sides opposite each other. Therefore, for such sash sides, two glass strip edges are required, which extend from the frame strip to the adjacent sash side. By means of the device, the glass strip edge 11 can be correspondingly divided into two glass strip sides. First, when the glass strip 1 is removed from the discharge opening 28 of the grooving machine 1, the glass strip side is clamped by the gripping unit 31 in the manner described above. First, the gripping unit 31 is moved in the X direction in synchronization with the feeding of the slotting machine 1, and then the gripping unit is completely pulled out from the slotting machine 1. The grip unit 31 is then moved up into the transfer position in the Z direction. The gripping unit 32 moves along the X direction along the track 44, and then causes the track to move in the Y direction on the lateral brackets 45, 46. To the extent that the grip unit 32 is located beside the grip unit 31. The bracket 52 is then moved a certain degree in the Z direction to clamp the glass strip edge 11 by the gripping unit 32. The glass strip 11 is pressed against the upward abutment surface 83 of the pressing element 54 by the clamping element 89 (Fig. 9). The clamping element 53 above the gripping unit 32 clamps the glass strip 11 from top to bottom.

Subsequently, the clamping of the grip unit 32 enters a no-pressure state. In this way, a small air gap of about 1/10 to 3/10 mm is produced between the clamping elements 53, 54, 89 and the glass strip 11 , the glass strip being fixed to the clamping elements 53 , 54 through the four sides. Between 89 and the abutment surface 83. The upper clamping strip 53, the lateral clamping strip 89, the lower clamping strip 54 and the abutment surface 83 form a channel in which the glass strip edge 11 can be perfectly aligned and the gripping unit can also be The channel moves in the X direction.

The gripping unit is moved along the X direction along the glass strip edge 11 into a position in which the glass strip edge can be divided into two glass strip side members by a left miter saw 57 and simultaneously on the right glass strip side member. Perform the required beveling operation. That is, the length of the left member is taken into account in terms of the axial clamping position. Once this position is reached, the glass strip 11 is clamped by the grip unit 32. From this point on, the clamping applied through the grip unit 31 can be cancelled. As previously described, the gripping unit 32 is moved in a manner such that the gripping unit 31 travels along the track 44 toward the discharge opening 28 of the slotting machine 1 to receive the next glass strip edge 11 there.

The gripping unit 32 is moved to the left miter saw 57 in the manner described above such that the glass strip edge 11 gripped by the gripping unit enters the clamping station on the left miter saw 57 during the X-direction travel. 63, 84. A sensor disposed in the region of the clamping stations detects the left end of the glass strip edge 11. From this point on, the glass strip edge 11 can be moved in the X direction to a predetermined extent to perform the first beveling operation by the miter saw 57. Through this operation, the glass strip 11 is divided into two parts. A piece from which the left end of the resulting right glass strip member is chamfered. In this chamfering operation, the glass strip side 11 is clamped in the clamp stations 63, 84, so that a neat chamfer can be performed.

With the glass strip 11 clamped in the clamping stations 63, 84, the clamping of the gripping unit 32 enters a pressureless state, resulting in between about 1/10 of the clamping element and the edge of the glass strip. Small air gap of 3/10mm. From this point on, the gripping unit 32 can be moved along the X-direction along the right glass strip member to a degree such that the clamping elements are spaced a predetermined distance from the right end of the right glass strip member as described above. From this point on, the right glass strip side member is gripped by the grip unit 32 and the clamping in the clamping station 63 is cancelled. The left part continues to be clamped in the clamping station 84.

From this point on, the grip unit 32 can transport the right glass strip member in the X direction to the right miter saw 58. The clamping station 69 is open. After clamping by the clamping station 69, the right beveling operation is performed on the right glass strip side member. Since the two miter saws 57, 58 are chamfered at both ends of the right glass strip member, the right glass strip side member has an accurate component length.

After the chamfering operation is performed, the clamping of the gripping unit 32 enters a pressureless state, so that it can be moved along the X direction along the right glass strip side member until the gripping unit is located at one half of the right glass strip side member. Length. From this point on, the right glass strip side member can be gripped by the grip unit 32. In this case, the clamping of the right glass strip side member in the clamping station 69 is eliminated in such a way that the clamping elements 70, 72 are moved laterally or upwards. The right glass strip side member can then be stored in the intermediate storage rack 30 by the gripping unit 32 in the manner described above.

The debris accumulated on the right miter saw 58 during the beveling process falls through the passage into the waste container.

The left glass strip side member is clamped in a clamping station 84 (Fig. 9) located behind the left miter saw 57. The two clamping elements 85, 86 of the clamping station clamp the left glass strip side member from above and from the left side. The entire clamping station 84 is capable of moving in the Y direction in the direction of the arrow 87. To receive the left glazing side member clamped in the clamping station 84 by the gripping unit 32, the clamping station 84 is advanced a certain degree in the direction of the arrow 87 such that the left glazing side member and the miter saw 57 Separate enough distance. Thereby, the clamping elements 53, 54, 89 of the gripping unit 32 can receive the left glass strip side member. This left glass strip side member is conveyed by the gripping unit 32 to the miter saws 57, 58 to perform beveling at both ends.

With the apparatus of the present invention, beveling can be performed only on one end of the glass strip side 11. If a bevel is to be performed on the left side of the glass strip 11, the process is the same as that described above for the beveling on both sides. After the glass strip 11 is transferred from the gripping unit 31 to the gripping unit 32 in the manner described above, the glass strip is conveyed to a certain extent by the gripping unit 32 until the area of the left miter saw 57 is located. The sensor inside detects the front end of the strip to accurately determine the axial position in the device. In other operations, the strip side is always either clamped in one of the clamping units or clamped in the gripping unit 32 so that the position is no longer lost. Therefore, in other processing and processing, the glass strip edge can always be accurately positioned through the X-axis of the grip unit 32. The glass strip side is clamped in the clamping station 63, and a bevel cut is performed on the left end of the glass strip side 11 by a miter saw 57. At the same time or subsequently, the clamping of the gripping unit 32 enters a pressureless state, so that the gripping unit 32 can be moved to one half of the length of the glass strip side 11. At this point, the glass strip edge 11 is clamped and the base gripping unit 32 stores the glass strip side in the intermediate storage rack 30.

If a bevel is to be performed on the right side of the glass strip 11, the process differs from the previously described process of beveling on both sides in that no chamfering is performed at the left end. Since only the left oblique This process is required on the saw blade for the optical sensor for accurate position determination. If the right miter saw also has an optical sensor that detects the right end of the glass strip, the glass strip can also be immediately transported to the right miter saw. In this case, the self-carrying unit 31 is transferred to the gripping unit 32 in such a manner that the gripping unit 32 receives and clamps the glass strip edge at the right end of the side of the glass strip in the X direction. Other processes are as described above. The sides of the chamfered glass strips are stored in the intermediate storage rack 30 or fed into the blank strip side cart 81, depending on the particular desired and other operations.

Finally, the glass strip 11 may not be chamfered. In this case, on the discharge opening 28 of the slotting machine 1, the glass strip edge 11 is gripped by the gripping unit 31 in the manner described above and conveyed to the transfer position, in the transfer position The glass strip 11 is transferred to the grip unit 32 in the manner described above. The gripping unit feeds the glass strip edge 11 into the area above the slideway 80 (Fig. 2). In this case, the gripping elements of the gripping unit 32 are opened, so that the glass strip side 11 enters the blank strip car 81 through the chute 80.

Such glass strip edges do not necessarily have to be finalized in the slotting machine, for example only by planing. For example, in the case where the wood strip 2 is not used to manufacture a sash, but is used to manufacture a window frame, the edges of the glass strips accumulate. The window frame does not require a glass strip. The final processing of these pre-machined glass strip edges can be carried out in subsequent processing steps and the sashes can be made from such glass strip edges.

By means of the apparatus according to the invention, the strips 11 which have been finally shaped in the slotting machine 1 can be separated from the strips 2 which have been machined in the slotting machine 1 so that the strips 11 and the strips 2 are discharged in the slotting machine 1 The ports 28 are separated from one another. According to the subsequent processing purpose, the glass strip 11 is conveyed by the gripping units 31, 32 to the left miter saw and/or the right miter saw 57, 58 This performs a corresponding beveling operation on the glass strip side 11. In the region of each miter saw 57, 58 a clamping station is provided in front of and behind the saw so that the glass strip 11 is gripped or clamped during the beveling process. This allows the beveling to be performed accurately. The glass strip 11 can always be accurately inserted into the clamping stations by the gripping unit 32, in particular by positioning the gripping unit 32 in the region where the beveled end is required, in particular in the use of a longer length The edge of the glass strip 11 can thus accurately deliver the chamfered end to the clamping stations. The clips entering the pressureless state constitute the passage in which the glass strip edges have a small gap, so that the gripping unit 32 can enter different positions of the glass strip 11 along the side of the glass strip, wherein The straight state of the (especially longer) glass strips can be maintained or straightened to achieve reliable clamping, processing and transport of the glass strips 11 in the apparatus. That is, with the device, the final shape of the longitudinal side of the glass strip can be carried out in the slotting machine in a fully automated process, and the strip side can be separated from the strip, and downstream handling and processing can be used as needed. The device performs beveling so that the glass strips are ready for direct loading.

When the transfer is made, the gripping unit 32 always abuts first to the gripping unit 31 and clamps the glass strip side. If the glass strip 11 is to be gripped at another position, the grip unit 31 is brought into a pressureless state and travels in the X direction. In the case of unclamping, the glass strip side 11 sag and may be twisted by internal stress, so that the grip unit 32 cannot be gripped at a certain distance from the grip unit 31.

As an alternative to the gripping units 31, 32, other manipulators, such as robots, may also be employed. Depending on the required throughput or productivity, it is also possible to use only one gripping unit 32 or robot that takes the strip side out of the slotting machine and also transports the strip side to the strip side saws.

According to another embodiment, two gripping units 31 are arranged in the X direction in turn, and when the glass strip edge 11 leaves the slotting machine 1, after the speed synchronization is achieved, the first of the gripping units is as described above. The end of the discharge side of the glass strip is clamped. The second gripping unit located between the first gripping unit and the discharge side of the slotting machine in the passing direction remains stationary until the glass strip edge 11 is nearly separated, and then the second gripping unit is realized and Synchronize the speed and clamp the rear end of the glass strip, the right end. This makes it possible to achieve an optimum holding of the glass strip 11 at the point in time when the complete separation takes place.
