Description

The invention relates to a device for Processing of edges on profiled and plate-shaped Workpieces in a continuous process, with a rotating one Tool and one associated with it, the tool in Dependent on the tracer roller controlling the workpiece.

The object of the invention is one according to the aforementioned Kind built device to improve that for the edge processing using a special rotating tool relatively high wear area is used, which is dependent on tool wear simple and easily adjustable feeler roller for the Edge processing is controlled so that a long service life is achieved with perfect edge processing.

This object is achieved by the characterizing Features of claim 1 solved, the in the Advantageous design features listed subclaims and represent beneficial further training in problem solving.

The edge processing device according to the invention works with a flexible buffing or polishing disc or the like,  by a when the buffing or polishing disc is worn adjustable feeler roller is controlled.

The buffing wheel and the feeler roller are in one shared pivot lever and the feeler is regardless of the buffing wheel, depending on the degree of wear, adjustable.

The axis of rotation of the feeler roller is almost always outside the axis of rotation of the buffing wheel and the feeler roller always back to the processing area of the buffing wheel.

The tracer roller is perpendicular to the pass plane of the Workpiece and the buffing wheel is more advantageous Way arranged perpendicular to this pass plane, because of the flexibility of the buffing wheel, even with a vertical one Position, the frontal and longitudinal marginal edges of the profiled workpieces perfectly recorded and processed can be.

However, there is also the option of Buffing wheel in an inclined or inclined position adjust.

Anything can be done with this buffing or polishing disc vertical and convex profile edges, such as radii and bevels, to edit.

The feeler roller is smaller in diameter than that Machining diameter of the buffing wheel executed and if the buffing wheel is worn, the diameter of the Buffing wheel be smaller than the feeler roller, but through Adjustment of the feeler roller protrudes from the processing area of the Buffing wheel always over the sensing area of the sensing roller out.  

Tolerances in the sensing area of the sensing role play for the Buffing wheel doesn't matter due to its flexibility, but they become flawless thanks to the buffing wheel balanced.

Because it is perpendicular to the workpiece Tracer roller the entire height range of the front and rear Front edge of the workpiece cannot capture it is preferred, two in the direction of passage of the workpiece Arrange pairs of tracer rollers, each with a buffing wheel, so the top of the front edge and the back Edge and the lower area of the front and rear edge of the Workpiece can be detected properly.

In this case, it is preferred that the pairs of feeler rollers against one another and to provide pivotable into their space, so that the two pairs of rollers take up little space Take the direction of the workpiece.

Due to the relatively large wear area of the Buffing wheel and easy adjustment of the feeler roller the processing unit has a long service life been so that the replacement of the buffing wheel in larger time intervals can take place.

The particular advantage of the invention is that for Machining tool (buffing or polishing disc) only one tracer roller running on a workpiece reference surface is required.  

Based on the drawings, a Embodiment according to the invention explained in more detail. It shows:

Fig. 1 is a front view in partial section of the edge with pivotable Bearbeitungsvorrichung buff and associated sensing roller,

Fig. 2 is a schematic side view of the buffing wheel and tracer roller in two reclined positions of the feeler roller and the starting diameter and worn diameter of the buff,

Fig. 3 is a schematic side view of a processing unit formed from a plurality of buffing wheels with feeler rollers for the front and top and bottom edge machining of a continuous workpiece.

The device for processing the edges ( 1 a, 1 b, 1 c) on profiled and plate-shaped workpieces ( 1 ) in a continuous process has a rotating tool ( 2 ) and an associated tool ( 2 ) depending on the workpiece ( 1 ) controlling feeler roller ( 3 ).

According to the invention, the rotating tool ( 2 ) is formed by a flexible buffing or polishing disc or the like, which in the workpiece passage direction (A) on the front edge ( 1 d) and on / on the top / bottom ( 1 e) of the Rolling workpiece ( 1 ), perpendicular to the workpiece passage plane, is traced by a roller ( 3 ); The buffing wheel (2) and the follower roller (3) are mounted on a common pivot lever (4) and the follower roller (3) against the wearing off in the processing diameter of the buff (2) continuously adjustable.

The diameter (TD) of the feeler roller ( 3 ) is smaller than the initial diameter (SD) of the buffing wheel ( 2 ) and the feeler roller ( 3 ) lies at the exit diameter (SD) of the buffing wheel ( 2 ) with its axis of rotation ( 5 ) outside of it Rotation axis ( 6 ) of the buffing wheel ( 2 ).

In the case of buffing wheel wear, the feeler roller ( 3 ) is adjusted relative to the wearing buffing wheel diameter (ASD) in such a way that even when a diameter (ASD) of the buffing wheel ( 2 ) that is smaller than the feeler roller diameter (TD) is reached, this is also included their processing area (X) protrudes beyond the feeler roller ( 3 ) ( Fig. 1 and 2).

The feeler roller ( 3 ) is adjusted in the direction of wear to the buffing wheel ( 2 ) on the swivel lever ( 4 ).

The effective scanning range (ATB) of the feeler roller ( 3 ) is asymmetrical to the direction of adjustment of the feeler roller ( 3 ) relative to the buffing wheel ( 2 ) ( Fig. 2).

The feeler roller ( 3 ) runs with its axis of rotation ( 5 ) parallel and in a limit case when it is adjusted coaxially to the axis of rotation ( 6 ) of the buffing wheel ( 2 ).

The swivel lever ( 4 ) is made up of several parts and has an adjustment lever ( 7 ) which rotatably supports the feeler roller ( 3 ) and which is supported by means of an adjustment guide ( 8 ) on a bracket ( 10 ) which can be swiveled about the swivel axis ( 9 ) and on which the buffing wheel is attached ( 2 ) load-bearing drive ( 11 ), such as an electric motor, is flanged.

The multi-part swivel lever ( 4 ) is held on a device bearing ( 12 ) with the feeler roller ( 3 ) and the buffing wheel ( 2 ) with its swivel axis ( 9 ).

As seen from Fig. 1, the follower roller (3) with its lever (7) independently of the buff (2) against the same infinitely adjustable and the buff (2) with its drive (11) by a bearing flange (13) on the also fixed the adjustment lever ( 7 ) receiving bracket ( 10 ).

The feeler roller ( 3 ) lies mainly with its axis of rotation ( 5 ) outside the axis of rotation ( 6 ) of the buffing wheel ( 2 ) and both axes of rotation ( 5 , 6 ) only come in one position when the buffing wheel ( 2 ) is inevitably adjusted due to wear Tracer roller ( 3 ) in coaxial coverage.

The buffing wheel ( 2 ) is preferably also perpendicular to the passage plane of the workpiece ( 1 ), so that the buffing wheel ( 2 ) and feeler roller ( 3 ) run side by side at a parallel distance.

There is also the possibility of tilting and / or tilting the buffing wheel ( 2 ) with its drive ( 11 ) on the bracket ( 10 ) of the swivel lever ( 4 ) with respect to the workpiece ( 1 ) and with respect to the vertical feeler roller ( 3 ) at an adjustable distance by means of an axis ( 14 ) and a sliding piece ( 15 ).

During the passage of the workpiece (1), the follower roller (3) and the buff (2) is located in the workpiece pass-line and the follower roller (3) first comes against the front end edge (1 c) of the workpiece (1) and then from the workpiece (1) is pivoted with its pivot lever (4) to the top (or bottom), thus running on the front end edge (1 d), and thereby the vertical, oblique or curved is edge (1 c) of the workpiece (1) by buffing processed by means of the rotating disc ( 2 ). Then the sensing roller ( 3 ) runs on the top (or underside) ( 1 e) of the workpiece ( 1 ) and when the rear end edge ( 1 d) of the workpiece ( 1 ) is reached, the sensing roller ( 3 ) with the buffing wheel ( 2 ) again downwards or upwards and then the rear vertical, oblique or curved edge ( 1 c) is buffed.

Machining by buffing or polishing can be carried out on all profile edges with vertical edges, with convex radii and bevels. However, since the feeler roller ( 3 ) and thus the buffing wheel ( 2 ) can only grasp and process a part of the height of the upright edge ( 1 c) and can only process the upper or lower longitudinal edge ( 1 a, 1 b) when the workpiece is passed through , it is advantageous to provide the moving workpiece ( 1 ) with a processing unit consisting of a sensing roller ( 31 ) with a buffing wheel ( 2 ) for the upper workpiece front edge ( 1 c), a sensing roller ( 32 ) with a buffing wheel ( 2 ) for the lower workpiece Assign rear edge ( 1 c), a feeler roller ( 33 ) with a buffing wheel ( 2 ) for the upper workpiece rear edge ( 1 c) and a feeler roller ( 34 ) with a buffing wheel ( 2 ) for the lower workpiece front edge ( 1 c), as Fig. 3 shows.

The two tracing rollers ( 31 , 32 ) with an associated buffing wheel ( 2 ) for the upper workpiece front edge ( 1 c) and the lower trailing edge ( 1 c) as well as the two tracing rollers ( 33 , 34 ) with an associated buffing wheel ( 2 ) for the upper workpiece rear edge ( 1 c) and lower workpiece front edge ( 1 c) each form a pair of disks / rollers which can be swiveled into one another and one after the other as a function of the workpiece ( 1 ) passing through.

From Fig. 3 the pivoting of the associated roller pairs ( 31 , 32 ) and ( 33 , 34 ) is shown in dash-dotted lines, the one roller ( 31 ) or ( 32 ) ( 33 ) or ( 34 ) with its buffing disc ( 2 ) can only pivot when the other feeler roller ( 32 ) or ( 31 ) ( 34 ) or ( 33 ) is pivoted and thus space for the roller ( 31 ) or ( 32 ) ( 33 ) or ( 34 ) to be pivoted subsequently has made.

This arrangement and mutual swiveling of the roller pairs ( 31 , 32 / , 33 , 34 ) has achieved a relatively short throughput space, for example of 1100 mm.

There is also the possibility for the upper front and rear edge (1 c) in the passage direction (A) of the first two upper sensing rollers (3) each having a buffing or polishing disc (2) and behind the lower front and rear edge (1 c) to arrange two lower feeler rollers ( 3 ), each with a buffing or polishing disc ( 2 ), but a longer passage, for example of 1500 mm, must be accepted.

The asymmetrical scanning area (ATB) of the feeler roller ( 3 ) shown in FIG. 2 results from the fact that it can only ever detect a partial area of the height of the front edge ( 1 c).

The distance differences (Y 1 , Y 2 ) between the two edge areas of the scanning area (ATB) from the buffing wheel ( 2 ) that arise during the tracing roller adjustment have no effect, since the flexible buffing wheel ( 2 ) compensates for these differences.

For example, the feeler roller ( 3 ) has a diameter (TD) of 170 mm and the buffing wheel ( 2 ) has an initial diameter (SD) of 200 mm and can be worn down to a diameter (ASD) of 160 mm.
