Definitions
- the invention is based on a method for making available an elongated molding and for inserting the molding in a hollow profile rod with a constant over its length cross-section with a given width and height. From the molded part, a frame-shaped spacer for insulating glass panes is subsequently formed, in which the molded part bridges a gap in the spacer.
- Plug connector for the insertion process in a defined position takes.
- the connector must be isolated the plug tool and fed in a defined orientation. It is known to use vibratory conveyors for this purpose.
- Insulating glass panes are manufactured with different distances between the individual panes of glass. Most of the distance is in the range between 6 mm and 30 mm.
- insulating glass panes with varying formats and varying distances between their glass panes are produced in irregular succession, depending on the order received. Accordingly, you need spacers with different width and accordingly also connectors with correspondingly different width. This has the consequence that you hold on a glass manufacturing line connector with different widths on stock and - in the automated production of frame-shaped spacers - must also provide their own vibratory conveyor for each connector. This is complex, especially since the vibratory conveyors need plenty of space, represent a costly investment and are also prone to failure.
- curved spacers can also be formed from more than one hollow profile bar. Since the hollow profile bars are usually produced in fixed lengths of eg 5 m, it is useful for insulating glass panes with a circumference of less than 5 m to avoid waste, to connect the hollow profile bars by connectors endlessly together. Such a compound of hollow profile bars in succession is mandatory if a frame-shaped spacer is to be manufactured for an insulating glass pane whose circumference is greater than the length of a single hollow profile bar.
- hollow profile rods rectangular spacer frame by first cut four hollow profile bars in the required length for the four legs of the spacer frame and then connects these four legs together by right angle elbows, which in the holder at a corner of the space abutting ends two hollow profile bars are introduced.
- right angle elbows which in the holder at a corner of the space abutting ends two hollow profile bars are introduced.
- straight connectors you need in this case for insulating glass with different disc spacing different width elbows, for each spacer four pieces that - if they are to be inserted automatically - are also supplied by different vibratory conveyor.
- the present invention has for its object to provide a way as straight connectors and / or angle pieces for spacers in insulating glass can be supplied with less effort and introduced into a hollow profile bar.
- a strand-shaped semifinished product which has a has constant cross-section over its length.
- the semi-finished product is positioned relative to a cutting tool so that a predetermined distance of the semi-finished on one side and the remaining portion of the semi-finished product on the other side of the cutting tool and measured in the longitudinal direction of the semi-finished length of the predetermined section on the clear width of the hollow profile bar is tuned, in which the molding is to be inserted.
- the predetermined section of the semifinished product is gripped by means of a mechanical gripper and only then separated from the strand-shaped semifinished product.
- the molding formed by the separation is inserted without releasing it in the meantime, with a gripper in the hollow profile bar.
- the invention makes a fundamental departure from the previous approach in the manufacture of frame-shaped spacers for insulating glass panes.
- the inserted into the hollow profile bar moldings, whether straight connectors or contra-angles, are no longer produced in a single mold technology, delivered in containers, separated by vibrating conveyor, fed, taken and plugged, but they are in place in the operation of an insulating glass manufacturer, in spatial Relation to the facilities with which the insulating glass manufacturer, the spacers are made, formed from a strand-shaped semifinished product with a constant over its length cross-section by cutting individually in the order required for the spacers to be produced.
- Differently wide and equally high connectors are inventively formed from one and the same strand-shaped semifinished product with the individually desired width by cross-cutting.
- the sections to be separated from the semifinished product are first gripped by means of a mechanical gripper, then separated and subsequently inserted into the hollow profile rod, without the molded part - a straight connector or a threaded connector.
- kel Culture - to be released in the meantime.
- the strand-like semi-finished products required for the method according to the invention can be produced inexpensively, either by extruding from metal, in particular from aluminum or from an aluminum alloy, or by extruding plastic.
- the use of a strand-shaped semifinished product made of plastic is preferred because plastics are less expensive than aluminum and, because of their lower heat conductivity compared to metals, allow insulating glass panes with a lower heat transfer value than spacers made of metal hollow profiled bars.
- Plastics with a strength that meets the typical conditions of use in an insulating glass pane, are known in the art. Suitable z.
- polyamides polyethylene, polypropylene, polystyrene, polycarbonate, polytretrafluoroethylene and ethylene-propylene terpolymer (EPDM). These are also suitable for the extrusion of hollow profile rods made of plastic. However, mostly hollow profile bars for spacers are made of aluminum or steel, in particular stainless steel.
- Hollow-section bars can be transported and stored in a cost-effective and space-saving manner as connectors and contra-angle handpieces produced in single-forming technology.
- the strand-like semi-finished products can be procured from a supplier, but also produced by the insulating glass manufacturer.
- the molded parts are under positive mechanical control from their manufacture by separation from the semi-finished product to insertion into the hollow profile rod. Random, disorderly movements that could complicate the gripping and insertion of the connectors or elbows can be excluded according to the invention.
- the separated from the semi-finished molding is inserted by means of the same gripper in the hollow profile bar, which holds it already during the separation of the semifinished product.
- This is the apparatus and movement of the simplest way of working. But it is also possible to proceed so that the molded part of the gripper, which holds the molding when separating the semi-finished, passed to a second gripper and is inserted by this in the hollow profile bar. With this procedure, shorter cycle times can be achieved because the processes of separating and inserting into a hollow profile rod can take place side by side in terms of time.
- the moldings are inserted without play or largely free of play in the predetermined hollow profile bars and held captive therein, preferably by friction.
- This can be achieved with suitably dimensioned rigid moldings, but also with moldings which, in addition to sufficient rigidity and dimensional stability, also have a certain resilience which gives rise to a restoring force.
- the shaped parts will be elongated, possibly angled structures.
- the molded parts produced by transverse division of the strand have a longitudinal section which coincides with the cross section of the strand-shaped semi-finished product.
- the method according to the invention is carried out so that the cutting tool and the hollow profile rod, in which the molded part to be separated is to be inserted, are arranged in a fixed spatial relationship, which is chosen to be consistent for each separating operation and for the subsequent insertion. Furthermore, it is advantageous to arrange the cutting tool so that it has a constant parting plane.
- the hollow profile bar is arranged parallel to the parting line of the cutting tool, in particular parallel to the predetermined portion of the semi-finished product, which is to be separated, and that the gripper for inserting the molded part in the hollow profile bar exclusively a translatory Movement performs. All these four measures mentioned serve to simplify the movement for the transfer of the moldings from the cutting tool into the hollow profile bar into it, the solid spatial relationships
- Fix points or fixed reference points or reference lines for the movement of the gripper which simplify its control, help prevent incorrect positioning and promote fast operation.
- the separating tool and the end of the hollow profile bar, in which the shaped part is to be inserted first are arranged in a fixed spatial position Relationship to each other.
- the separating tool and at least one of the two hollow profile bars, preferably both hollow profile bars into which the angle piece is to be inserted, are arranged with their ends in a fixed spatial relationship to one another at.
- the molded part may also be a two-legged structure, which is foldable from an extended position to an elbow, with which two hollow profile bars can be connected to each other via corner.
- Foldable elbows are known from the USA by prior use, but prefabricated in single mold technology. If a molded part, which is foldable to an elbow, processed, one preferably moves so that the cutting tool and at least one of the two hollow profile bars are arranged for this purpose with one of its ends in a fixed spatial relationship to each other.
- a further advantageous embodiment of the invention is that the hollow profile bar at the locations where a corner of the spacer is to be formed, with a extending over the corner away recess provides for the production of a spacer with curved corners, without the hollow profile bar there completely to sever, that then you insert a molding, which is a sauschenkliges structure and from an extended position to an elbow through the recess into the still elongated hollow profile bar and then forms the corner of the spacer by the hollow profile bar together with the in it located molding bends.
- the molding must not secure the cohesion of the corner, but the predetermined angle, which should have the spacer at the corner.
- Such two-legged structures which can be folded into an angle piece and spacers with a continuous outer wall produced therewith are disclosed in German patent application DE 10 2005 037 303.8 with priority from January 18, 2005, to which reference is hereby made for further details. Reference is made.
- Such two-legged structures which can be folded into an angle piece can likewise be manufactured and processed extremely inexpensively by the method according to the invention.
- the method is preferably carried out so that the cutting tool and the respective recess in the hollow profile rod, in which the durable molded part is to be inserted in be arranged in a fixed spatial relationship to each other.
- the hollow profile rod preferably has an outer wall which forms the outside of the spacer and remains untouched in the formation of the recess. Rather, the recess should extend at the point provided for the corner from the inner wall of the hollow profile rod opposite the outer wall in the two flanks of the hollow profile rod, which later face the glass panes of the insulating glass pane, in the direction of the outer wall, without severing them.
- the recess on the later inner side of the spacer on both sides of the corner provided for the point to extend, to an overall length which is smaller than the length of the foldable molding, so that this after the Insertion in the hollow profile bar captive caught in it.
- the semi-finished product is preferably cut between counter-movable cutting edges of the cutting tool. This has the advantage that its tendency to shift during the cutting process is low, which in turn facilitates gripping in the gripper.
- the cutting edges can be movable knives act. But it is also possible to cut the semifinished product by means of a rotating cutting tool, in particular to saw, which comes in particular for metallic semi-finished products and for angular semi-finished products in question.

- Figures 17 to 22 show successive stages of transfer and insertion of the foldable molding into a hollow profile rod.
- Figure 1 shows a cutting tool 1 with a stator 2, in which two mutually parallel blade holder 3 and 4 are mounted in opposite directions parallel to each other displaceable.
- the structure of the separating tool 1 is shown in detail in Figures 5 to 8.
- the first knife holder 3 carries a first knife 5.
- the second knife holder 4 carries a second knife 6.
- the two blades 7 of the blades slide past each other during the separation process and define a parting plane 8.
- stator 2 In the stator 2 is a perpendicular to the parting plane 8 extending shaft 9 gela- on which an eccentric lever 10 is fastened, which is pivotable back and forth by a pressure cylinder 11.
- eccentric lever 10 On the eccentric lever 10, two rollers 12 and 13 are attached.
- the rollers 12 and 13 are freely rotatable about axes which are parallel to the shaft 9 and arranged eccentrically with respect to the axis of the shaft 9.
- the first roller 12 is arranged in a cutout 14 of the first knife holder 3.
- the second roller 13 is mounted in a cutout 15 of the second knife holder 4.
- the two cutouts 14 and 15 are the diameter of the rollers 12 and 13 adapted slots, which serve to guide the rollers 12 and 13.
- the rollers 12 and 13 By operating the pressure cylinder 11, the rollers 12 and 13 move due to their eccentric bearing in opposite directions up and down, thereby causing an opposite movement of the blades 5 and 6 between the position shown in position 7, in which the arrangement of the blades 5 and 6 open is, and the position shown in Figure 8, in which the arrangement of the blades 5 and 6 is closed and a separation process is completed.
- the cutting tool 1 is perpendicular to the parting plane 8, a strand-shaped semifinished product is supplied, which in the example of Figure 1 is an extruded plastic profile, which consists of a plate 17 on which on both sides of a centrally disposed web 18, which the plate 17th crosses at a right angle, a series of fins 19 is provided which extend obliquely to the plate 17 in such a way that their free ends are directed obliquely in the direction of the web 18.
- the semifinished product 16 can be gradually moved and fed to the cutting tool 1.
- the separating tool 1 can separate 16 different-width molded parts 22 of the semi-finished product, of which three examples are shown in Figure 1.
- the semifinished product 16 is advanced by means of the jaws 20 and 21 until a section 16a corresponding to the desired width of the shaped part 22 projects beyond the parting plane 8, see FIG.
- a gripper 24 is provided, which has two jaws 25 and 26.
- the gripper 24 is displaceable on the one hand in a direction perpendicular to the parting plane 8. This direction is shown by an arrow 27.
- the gripper 24 is displaceable in a direction parallel to the parting plane 8 and parallel to the plate 17 of the semi-finished product 16; this direction is shown by an arrow 28.
- the two directions of movement are sufficient to transfer a connector 22 from the cutting tool 1 in a hollow profile rod 23 when it is in a matched to the cutting tool 1 reference position in which the hollow profile rod 23 parallel to the parting plane 8 and parallel to the cutting edges 7 of the knife. 5 and 6 and in the amount of the semi-finished product 16.
- the gripper 24 already grips the section 16a of the semifinished product 16 protruding beyond the parting plane 8 before it is cut off.
- the gripper 24 holds the portion 16a during the cutting process. This is easily possible because the blades 5 and 6 move in opposite directions and perpendicular to the plate 17 of the semi-finished product 16, so that the cutting process is virtually no tendency to shift the portion 16 a. If the portion 16a is cut off, and thereby the connector 22 is formed, it removes the gripper 24 from the cutting tool 1 in the direction of arrow 27 until it is in alignment with the hollow profile rod 23, see Figure 2.
- the gripper 24 moves in the direction of Arrow 28 - see Figure 3 - and puts the connector 22 in the hollow section bar 23 until the web 18 abuts the edge of the hollow section bar 23.
- the hollow profile rod 23 is fixed for this purpose in its predetermined position, e.g. clamped or positioned against a stop.
- the semifinished product 16 is already advanced a bit further by the pliers with the jaws 20 and 21 to the separating cut for to prepare the next molded part 22.
- the gripper 24 opens, moves against the direction of arrows 28 and 27 back to the cutting tool 1 and there takes the now positioned next section 16a of the semifinished product.
- the end of a further hollow profile rod 23a can be inserted onto the section of the connector 22 projecting from the hollow profile rod 23, as shown in FIG.
- the connector 22 is always in a defined position; he is never left to himself. This allows the process to be carried out at high speed and with high precision.
- the gripper 24 moves, regardless of the width of the connector 22, only consistent paths. It can be based on the same reference lines despite different width connector 22:
- As a first reference line 31 the center line between the two cutting edges 7 and 8 is suitable.
- As a second reference line 32 is a longitudinal edge of the forcibly positioned and supplied semi-finished product 16, for example, in Figure 1 shown left edge of the semifinished product 16, soft on the left edge of the jaws 25 and 26 of the gripper 24 can be aligned, or the web 18.
- a third reference line 33 determines the altitude of the hollow section bar 23 and a fourth reference line 34 sets the Position of the end of the hollow section rod 23 fixed, in which the connector 22 is to be inserted.
- the sequence shown in FIGS. 1 to 4 is not mandatory.
- the altitude (reference line 33) of the hollow section bar 23 can be chosen differently.
- the gripper 24 must then additionally be able to perform a movement in a direction perpendicular to the arrow 27 and perpendicular to the arrow 28. It is also possible to perform with the gripper 24 only a reciprocating movement in the direction of the arrow 27 and to perform the connector by moving the hollow profile rod 23 against the gripper 24.
- FIGS. 9 to 15 differs from the exemplary embodiment illustrated in FIGS. 1 to 8 in that the semi-finished product 16 has a different cross-sectional shape such that the severing tool 1 does not operate with two knives which are displaceable relative to one another but with a rotating cutting disc 35 which can be designed in particular as a saw blade.
- a collecting device 36 is provided under the cutting disk 35, in which the cutting disk 35 is partially immersed. Any supporting and guiding devices for the semifinished product, which can be arranged between the pliers with the jaws 20 and 21 on the one side and the separating tool 1 on the other side, are omitted in FIG. 9 as well as in FIG. 1 for reasons of clarity.
- the gripper 24 is of similar construction as in the example of Figure 1, but is additionally pivotable about an axis 37 which is perpendicular to the cutting wheel 35 and thus perpendicular to the parting plane 8.
- the strand-shaped semi-finished product 16 has in cross-section two equally long legs 38 and 39, which are connected by a foil joint 40.
- the two legs 38 and 39 have on one side flexible blades 41, which protrude a little above the foil joint 40.
- the side facing away from the slats 41 of the legs 38 and 39 is - apart from an insertion bevel 42 at the tips of the legs 14, 15 - flat and extends in an extended position of the legs parallel to the outside of the film hinge 40th
- a stop 43 and 44 is formed by the height of the legs 38 and 39 is increased stepwise approximately to the thickness of the wall of the hollow profile bar 23 in the vicinity of the foil joint 40.
- the leg 39 has in the vicinity of the foil joint 40 a recess 45 which is open on its side facing the opposite leg 38.
- the leg 38 in the vicinity of the foil hinge 40 has a hook 46 which points in the direction of the tip of the leg 38.
- the hook 46 is the recess 45 in the other Schwenkel 39 opposite.
- the hook 46 is formed and arranged so that it engages in the opposite recess 45 when the two legs 38 and 39 are pivoted about the foil joint 40.
- the hollow profile bar 23 has an outer wall 48, two flanks 49 and an inner wall 50 parallel to the outer wall 48. At one location of the hollow profile bar 23 at which a corner is to be formed, it is provided with the recess 47 extending from the inner wall 50 to extends into the flanks 49.
- flanks 49 there are two mutually congruent opposing parts of the recess 47, which have the shape of a rectangular miter cut, the top of which is equal to the inside of the outer wall 48 and determines the position of a bending axis around which the corner is to bend.
- the inner wall 50 is removed over a predetermined length in its entire width, this length being distributed uniformly on both sides of the miter cut.
- the gripper 24 is first in the direction of arrow 27 of the cutting disk 35th removed until the molding 22 is located exactly above the recess 47 of the positioned in a predetermined reference position hollow profile rod 23. Then, the gripper 24 is pivoted about its axis 37, whereby the leg 39 dips into the recess 47 until it comes to lie flat therein, as shown in Figure 11. If necessary, the gripper 24 for this purpose can still be approximated perpendicular to the direction of the arrows 27 and 28 of the hollow profile rod 23.
- the gripper is not shown in FIG.
- the gripper is moved in the direction of the arrow 28, as a result of which the shaped part 22 is displaced into the hollow profile bar 23 as far as the stop at the edge of the recess 47, as shown in FIG.
- the gripper 24 then releases from the leg 38 of the molding 22, whereupon it automatically pivots into the recess 47 under the action of a restoring force originating from the film hinge 40 and assumes the position shown in FIG. Should the restoring force of the foil joint 40 not be sufficient for this, the leg 38 can additionally be acted upon by a ram, not shown, in order to press it into the recess 47.
- the molding 22 is now moved in the recess 47 to center it.
- the stop 43 is provided: If it hits the edge of the recess 47, the shaped part 22 is centered, as shown in FIG. In this position, both legs 38 and 39 lie with their ends under the inner wall 50, so that the molded part 22 is caught captive.
- the hollow profile rod 23 can now be transferred to another working position, in which it is bent at the location at which the miter cuts of the recess 47, folding the molding 22 to a corner. In the 90 ° position, the two legs 38 and 39 of the molding 22 lock automatically and thereby stabilize the corner, which advantageously has a continuous outer wall 48.
- the third embodiment illustrated in FIGS. 16 to 22 differs from the second embodiment shown in Figures 9 to 15 is that the gripper not only two jaws, but three jaws 52, 53 and 54 which are formed in the present case as cylindrical rods or fingers.
- the three jaws 52, 53, 54 are arranged parallel to each other so that a central jaw 52 is movable perpendicular to a plane spanned by the two outer jaws 53 and 54, between a first position in which the middle jaw 52 below this Plane is located, and a second position in which the middle jaw 52 is above this plane spanned by the two outer jaws 53, 54 level.
- the main body of the gripper which carries the jaws 52, 53 and 54 and their actuators is not shown for reasons of clarity.
- the portion 16a to be cut off from the semifinished product 16 is first grasped by the jaws 52 to 54 so that the two outer jaws 53 and 54 engage the upper side of the legs 38 and 39, while the middle jaw 52 engages the foil hinge 40 from below , After the separation of the molding 22, the gripper moves first perpendicular to the blade 35 in the direction of arrow 27 away from this until the molding 22 is located directly above the recess 47 of a located in a predetermined reference position hollow profile rod 23, wherein the reference position is selected so that the middle jaw 52 is perpendicular to the miter cuts of the recess 47, see Figure 17.
- the molding 22 is bent at its foil joint 40 around the middle jaw 52 around by the middle jaw 52 raised relative to the outer jaws 53 and 54 or the outer jaws 53 and 54 are lowered relative to the central jaw 52, see Figure 17.
- the gripper is moved perpendicular to the direction of the arrow 27 in the direction of the arrow 30 down, whereby the ends of the legs 38 and 39 dive into the recess 47 , as shown in oblique view in FIG. 18 and in a longitudinal section through the hollow-section bar 23 in FIG. 19 lt is.
