Description

Device for mounting a rung part in a frame

Technical field

The invention relates to a device for mounting a rung part in a frame with means for clamping the frame. State of the art

When producing insulating glazing with sight bars WLssen <1 det Sprossentci 1 mounted in the space between the panes, they are first mounted in a spacer frame and then the frame prepared in this way is glued to both sides with glass panes. The spacer frame is e.g. B. an aluminum hollow profile. Due to its light construction, it is flexible to a certain extent. The rung parts are made, for. B. from intersecting wooden bars. The connection at the crossing point also allows slight Winkelver shifts. When installing the window, care must now be taken that the rung part, e.g. B. a rung cross, is mounted at right angles and rarely parallel with respect to the frame.

It is known to fix the frame on a table with a drawn line grid and to use the rung part adjusted with respect to the grid lines. The disadvantage of this method is that the angular accuracy of the fully assembled rung part in the frame strongly depends on the ability and the current condition of the worker.

It is also known to predrill the frame at the required points and then to insert the rung parts provided with a corresponding pin. This requires not only a high drilling accuracy and a separate machining ^¬ processing step for the shoot parts (for the production of Zap¬ fen), but still has the drawback is that the square-wave perpendicularity not guaranteed. Presentation of the invention

The object of the invention is to provide a device of the type mentioned, which enables wi nkelgetrcue and quick assembly of rung parts in frames. Furthermore, the device should be suitable for assembling frames of different sizes without retrofitting.

According to the invention, the solution is characterized in that an angle template, which can be freely displaced in at least two different directions while maintaining the angular position, is provided with means for holding the rung part in a desired angular position, so that the rung part is adjusted to the desired angle Assembly position can be pushed and connected to the frame

The angle template specifies the target angle position (e.g. 90 ° position) for the rung part, specifically a rung cross. The rung part need not yet be in the desired assembly position. While maintaining its angular position (with respect to the clamped frame), the rung part can then z. B. can be moved freely in a predefined level. I.e. the rung part can be led to the frame and fixed there.

It is essential for the invention that first and second means are provided for clamping the rung part and the frame, at least one of the two means comprising an angle template for holding the rung part or frame in a desired angular position, and that zumin¬ least one of the two means in at least two directions at various ^¬ which Beibehα1tung the Winl- elΪ> tel 1ung Reid tive to the other -are free verbchiebbcu, so the DASB Rung part and frame can be pushed and connected to one another in a desired mounting position.

According to a particularly preferred embodiment, the angle template is guided on two crossing parallel arms. Each parallel arm ensures parallel guidance in one direction on a predefined level. It is also possible to work with only one parallel running arm on which the angle template can be moved in one direction. The leadership can instead be done with an articulated arm, in which z. B. the angular position of the angle template is kept independent of the arm position by cables (similar to a drawing device).

The parallel running arms thus ensure that the angle template can be displaced relative to the clamped frame while maintaining the angular position. The angle template is e.g. B. by two low-friction linear guide systems (roller bearings or the like) on the two parallel arms ge.

To ensure parallel guidance, the parallel-running arms can be guided on rails by two - preferably end-mounted - mechanically coupled loudspeakers. The carriages can advantageously be locked in any position. For this, e.g. B. pneumatically or electromagnetically actuated brakes may be provided. In order to facilitate the assembly of individual rungs, a travel sensor can also be attached to the carriage to enable positioning according to the specified dimensions. The position of the transducer is z. B. digitally displayed. According to a further preferred embodiment, at least one parallel running arm is equipped with a clamping device, which is aligned with the angle template and can be used to fix one end of the rung part. A rung cross is therefore not touched at an angle in the center, but also at the end to be assembled. This jig is z. B. pneumatically or electromagnetically actuated.

The parallel arms can also have a device for attaching the rung part to the frame. So z. B. a nail gun aligned with the parallel arm, respectively. the clamped rung part be present, which can be applied and operated from the outside on the clamped frame. This has the advantage that the fastening pin is always shot in the right place. There are no target and bullet mistakes.

The angle template has z. B. a 90 ° -Sollwιnkelanschlag for a rung cross. A z. B. pneumatically or electro-magnetically actuated clamping device fixes the cross bar at the set angle stop. A particularly simple clamping device is characterized by a clamping slide that can be displaced on a bisecting line of the 90 ° setpoint stop. This therefore engages on the side of the rung cross which is diametrically opposite to that lying against the set angle stop. The clamping slide advantageously has a head which can be rotated about an axis perpendicular to the set angle stop. In this way, he can lay down flexibly on the cross of the rung part. This solution is particularly advantageous when rung parts of different thicknesses and cross bars with cross arms of different thicknesses are to be correctly clamped straight away and without problems. The device according to the invention can also be used for the assembly of rung parts with several cross points. Two or more angle templates can be provided by providing at least two parallel arms and at least one parallel to the first mentioned parallel arms and by an angle template being guided in each crossing point of the parallel arms. With three parallel arms two angular templates are possible, with four parallel arms four angular templates are possible.

If several angle templates are required, the solution with the parallel arms is superior to that with the articulated arms (simpler design, no risk of collision).

Further advantageous embodiments and combinations of features result from the detailed description and the entirety of the claims.

Ways of Carrying Out the Invention

1 has a rigid, rectangular frame construction which is formed by four rails 1.1, 1.2, 2.1, 2.2. They serve in pairs for the management of z. B. each have a parallel arm 3, 4. The parallel arm 3 is equipped at its ends with a carriage 5.1, 5.2, which on the rail 1.1, respectively. 1.2 is running. Analogously, the parallel arm 4 has two carriages 6.1, 6.2, which run on the rails 2.1, 2.2 parallel to one another. The parallel arms 3, 4 are at right angles to each other and can accordingly only move in the two mutually perpendicular directions of travel.

In the present example, the rails 1.1, 1.2 are longer than the rails 2.1, 2.2. This is because the spacer frames for Isoller glazing (which represent a preferred example of use) are generally rectangular. Basically, the shape and size of the frame construction are not important. It should also be noted that the perpendicularity is not mandatory, but rather results from the application chosen here.

The angle template 7 is located at the crossing point of the two parallel running arms 3, 4. It is supported on the parallel running arms 3, 4 with low friction. It follows from the preceding explanations that the angle template 7 can be moved freely in a predefined plane (within the frame construction defined by the rails 1.1, 1.2, 2.1, 2.2) while maintaining the angular position (relative to the frame of the device mentioned) .

At the intersection of rails 1.1 and 2. 2, a corner bracket 8 is rigidly mounted. It serves to clamp a spacer frame 11 (hereinafter referred to as frame 11) in which a crossbar 12 is to be mounted.

Before further details of the assembly device are to be dealt with, the handling will now be briefly explained.

In a first step, the frame 11, which in principle can have any dimensions, is placed on the device and fixed with the corner bracket 8 (cf. FIG. 1). Stops are provided on the carriages 5.2, 6.2, which are aligned with the corner bracket 8 and ensure that the corresponding sides of the frame 11 are exactly at right angles to one another. The perpendicularity "is thus guaranteed, regardless of where the parallel jaui ar im i, 4 are. In the next step, the cross bar 12 is placed in the angle template 7 (cf. item A of the cross bar 12). The clamping device provided on the angle template 7 is actuated and clamps the cross bar 12 exactly at a right angle. The rung cross 12 (which, as mentioned at the beginning, consists, for example, of two intersecting wooden profiles) is not absolutely rigid in itself, but can still change slightly in terms of angle. This minimal mobility is thus used during clamping in order to reach the desired angular position.

Now the crossbar can be moved from the (any) position A to the mounting position B. To do this, it is sufficient to grasp the angle template 7 and move it in such a way that the ends of the arms of the crossbar lie against the corresponding inner sides of the frame 11. When moving, the parallel running arms 3, 4 ensure that the angular position of the cross bar 12 with respect to the clamped frame 11 is maintained.

When the ends of the rung cross fit snugly on the two sides of the frame 11, which are above the rails 1.2 and 2 2, the corresponding ends of the rung cross 12 can be clamped with clamping devices which are provided on the carriages 5.2, 6.2 . The angle template 7 holding the cross bar 12 is thus also automatically held. Alternatively or additionally, locking devices of the carriages 5.1, 5.2, 6.1, 6.2 can be actuated in order to also fix the parallel running arms in this way.

Now the two clamped ends of the cross bar 12 can be connected to the adjacent sides of the frame 11. In the present example, thief happens by shoot a pen with the help of a nail gun 9, 10. Each nail gun 9, 10 is in the aligned position with the clamped cross bar 12, respectively. with the corresponding parallel running arm 3 resp. 4 arranged. It can be displaced in the direction of the corresponding parallel running arm 3, 4 in order to be able to be placed on the frame 11. It follows from what has been said that the pin is always shot centered with respect to the corresponding arm of the rung cross 11.

Next, all detents are released so that the frame 11 with the partially assembled cross bar 12 can be removed and rotated again by 180 °. The attachment of the two still free ends of the rung cross 12 proceeds in principle in accordance with the scheme already explained.

2 shows a representation of a preferred embodiment of an angle template 7. A first roller guide system 13 (linear guide) runs on the parallel arm 3 (shown in section in FIG. 2). It is rigidly connected to a second roller guide system 14, the latter rolling on the parallel running arm 4 (also shown only in part in FIG. 2). The directions of the two roller guide systems 13, 14 are perpendicular to each other.

2 that the parallel arms 3 and 4 are located in different planes.

On the upper roller guide system 13 in the present example there is a device for clamping a rung cross. This has three blocs niidet and 1-formly arranged bloc-t 1 ^' s, I ( ^• , i ⁿ are z. B-shaped, have a square base and are fastened in the corners of the square roller guide system 13. The two blocks 15, 16 form flush stop puddles 18.1, 18.2. Exactly right-angled? The two abovementioned stop surfaces 18.1, 18.2 are formed by the blocks 15 and 17 stop surfaces 19.1, 19.2 (which are hidden in the illustration according to FIG. 2).

The distances between the blocks 15, 16, 17 are so large that cross bars of different thicknesses can be inserted. A pneumatic cylinder 20 with a piston rod 21 and a head 22 is provided for fixing. The piston rod 21 moves on an angle bisector with respect to the stop faces 18.1, 19.1. The head 22 is essentially formed by a carrier which is articulated in the middle to the piston rod 21 and has two rollers 23.1, 23.2 at its two ends. The head 22 can be rotated about an axis perpendicular to the clamping plane of the crossbar (or the displacement directions of the angle template 7). When clamping the rung cross, the head 22 can adapt flexibly to the corresponding cross groove. The rollers 23.1, 23.2 prevent the rung cross from being damaged during clamping.

The pneumatic cylinder 20 is located in that corner of the roller guide system 13 which is diametrically opposite to that occupied by the block 15.

An embodiment of the carriage 5.2 is shown in FIG. 3. The frame 11 and the end of the cross bar 12 are drawn in dashed lines. On the carriage 5.2, the surface of which lies in the same plane as that of the roller guide system 13, a block 24 is mounted for the adjustment and fixing. Striking surface 27, which is flush with the stop surface 18.1 of the angle template 7 (cf. FIG. 2). The corresponding arm of the rung cross 12 is thus angularly adjusted both at the crossing point (through the stop surface 18.1) and at the end (through the stop surface 27). Opposite the block 24, a pneumatic cylinder 25 is provided which presses the arm of the cross bar 12 with the clamping head 26 against the stop surface 27.

The carriage 5.2 also has a block 28 with a stop surface 29 for the frame 11. The stop surface 29 is aligned with a corresponding stop surface of the corner bracket 8 (FIG. 1). The frame 11 is thus also fixed in its direction. Cross bar 12 and frame 11 can therefore be joined together at right angles.

A nail gun 9 is provided on the outer or rear side of the block 28, which can be moved towards and away from the frame 11. To shoot in the nail, it is placed on the frame 11, a guide (not shown) of the nail gun 9 inevitably ensuring that the nail is centered in relation to the arm of the cross bar 12.

The carriage 6.2 is essentially equipped in the same way as the carriage 5.2 just described.

Fig. 3 shows schematically a preferred embodiment to ensure the synchronism of the two carriages 5.1, 5.2 of the parallel arm 3. The rail 1.1 is z. B. laterally held by a carrier 30. A rack 31 is provided on its underside. A support 34 projects downward on the carriage 5.1. It has a bearing for a shaft 33. At the end of the shaft 33 there is a pinion 32 which clamps with the rack 31. The carriage 5.2 is symmetrical to the one just described. The shaft 33 (which runs in the same direction as the Paiallellautdπn 3) thus represents a mechanical connection between the two carriages 5.1, 5.2. Any displacement of the one carriage is forced via pinions 32 and shaft 33 ¬ commonly transferred to the other carriage

It should be noted that the distance between parallel arm 3 and shaft 33 makes it possible to move the parallel parallel arms through each other by arranging them at different heights without having to choose different designs.

The invention is of course not limited to the illustrated embodiments. So it is z. B. not mandatory that the angle template must run on two parallel arms. It can also be guided on a single one. However, only one end of the rung cross can then be held true to the angle (namely that which is in the same direction as the parallel arm).

It is also not imperative that the parallel arms are perpendicular to each other. It is sufficient if they cannot change their own angular position with respect to the clamped frame.

5 illustrates an articulated arm which can be used instead of the parallel running arms and has a fixed angular position of the end part. The construction is known per se and is therefore only briefly described. A circular disk 36 is fixed centrally in a fixed point 35. An arm 37 can also be rotated about the fixed point 35 at the opposite end of the arm 37 Smd concentrically mounted two circular disks 38 and 39 rotatably. The two circular disks 38, 39 are rigidly connected to one another and can only be rotated together about the axis of rotation 40. Another rotary arm 41 extends from the axis of rotation 40 and carries a circular disk 42 at the opposite end. Both the circular disks 38, 39 and the circular disk 42 are rotatably mounted on the arm 41.

The circular disks 36 and 38 have the same diameter and are connected by a cable 43. This is guided on the periphery of the circular disks 36 and 38 and holds the circular disks 36, 38 at an angle to each other. The circular disks 39 and 42 are connected by a cable 44. As a result, the circular disks 36 and 42 always have the same angular position, regardless of the position of the arms 37, 41. If the circular disk 36 is fixed to the frame structure of the device and the angle template is mounted on the circular disk 42, the angle template can be freely moved in one plane while maintaining the angular position. 5 is therefore essentially equivalent to the guides through parallel arms.

The size of the frame construction formed by the rails 1.1, 1.2, 2.1, 2.2 is in no way restrictive of the size of the spacer frame to be machined. The latter can be larger or smaller than the frame construction.

Also conceivable is a kinematic reversal in the sense that the sprout part is held stationary and the Abstandshal ^¬ terrahmen moves (while maintaining the angular position). The details shown with reference to FIGS. 2 to 4 can be replaced in their function by other constructions. The mechanical coupling via shaft and pinion can be let Wegge ^¬ if such. B. two spaced guide systems are provided at each end of a parallel running arm, which can ensure the required angular stability of the parallel running arm.

In terms of application, the invention is not limited to the assembly of rung parts in spacer frames. Rather, it can be used wherever a first construction element has to be connected simply and quickly to a second construction element. The connection between the two construction elements depends on the requirements and requirements of the individual case. Instead of pin connections, glue, soldering, welding or other connections can be made.

In summary, it can be stated that the invention has created a structurally simple and easy-to-use device which can be flexibly adapted to the mass of the assembly object and therefore has great advantages, in particular in production processes with small lot numbers.
