Abstract

The machining process involves machining the surfaces (2a) of flat workpieces (2) using rotating tools (5, 6). The workpieces and tools can move relative to each other. The surfaces can be machined selectively in the same machine tool by means of a tool unit containing a machining roll, e.g. a brush roll, and a tool unit containing plate-type tools.

Description

The invention relates to a method and an apparatus for processing surfaces of essentially flat workpieces, according to the generic term of claim 1 or according to the preamble of Claim 12.

Such methods and devices are used both for relatively large as well as for relatively small workpiece surfaces, for example for cleaning, grinding and Polishing the surfaces themselves as well as deburring from outside and inside edges of in any Cut out or punched out flat Workpieces used, for example made of sheet metal, Wood-based materials, plastics and the like manufactured could be.

For the aforementioned purposes, it is from practice already known, corresponding workpiece surfaces with rotating drivable processing tools edit, the workpieces generally under transported along the tools and thereby the tools against the workpiece surfaces can. Depending on the type of machining required, in the processing device either at least one Brush roller or at least one rotating sanding belt provided as a machining tool. Especially with the use of brush rollers and sanding belts it comes especially when editing from relative large workpiece surfaces are often undesirable Banding, which is why this processing rollers and grinding belts in addition to their orbital motion another roughly transverse to the workpiece transport direction aligned oscillatory movement is given however, which in many cases also leads to undesirable wavy shapes Strip leads.

In addition, for example from US-A-51 05 583 and EP-A-919 331 discloses devices in which a number of plate-shaped rotating around vertical axes Machining tools or brushes provided are, in addition to their own rotation by at least another common axis of rotation additional approximately planet-shaped Can perform rotary movements. This various rotary movements of the plate-shaped processing tools have the consequence that with simultaneous Feed movement of the workpiece several different Relative movements take place, whereby in different surface areas of the workpieces inevitably different intensive surface treatments be made. Apart from that is too consider that these known designs because of their basically processing tools rotating around vertical axes only for a limited type of surface processing can be used.

The invention has for its object a method according to the preamble of claim 1 and a device according to the preamble of claim 12 so that the processing device at relative low device effort and with optimal Machining result extremely reliable for very diverse Surface processing types can be used can.

This task is procedurally identified by the indicator of claim 1 and device-wise solved the characterizing part of claim 13.

Advantageous refinements and developments of Invention are the subject of the dependent claims.

A basic idea of the method according to the invention becomes seen in that the workpiece surfaces in at least a processing zone of the same processing device optionally by means of at least one processing roller containing first tool unit or one a group of plate-shaped processing tools containing second tool unit processed be, the processing roller approximately in its radial Direction and the plate-shaped editing tools approximately in their axial direction against the Workpiece surfaces.

The knowledge lies in this method according to the invention based on the fact that different workpiece surfaces and different types of materials only with optimally adapted processing tools can be edited. This can be a relatively large Group of surface types and types of materials especially cheap with roller-shaped processing tools and another large group of surface types and Material types particularly cheap with plate-shaped processing tools are processed, with the mentioned groups can partially overlap. If so in at least one processing zone one and the same processing device the at least a first tool unit containing a processing roller and the one group of plate-shaped machining tools containing second tool unit exchanged easily and relatively quickly can be extremely reliable and very diverse with optimal processing results Surface processing types (be it according to the Size and shape of the surfaces, be it in relation to the Type of material). It turns out especially as particularly advantageous if a Users of such a processing device only proportionately small quantities of workpieces with each specific types of surface processing or types of material (with the most suitable processing tools) edited and thus this processing device if equipped only with roller-shaped or only with plate-shaped processing tools would be completely underutilized.

It is special in this method according to the invention advantageous if one for each tool unit Tool storage frame with at least partially the same outer shape is used and each tool storage frame in the same recording subframe of a main fixture rack quickly replaceable can be installed or installed and removed.

According to a particularly preferred embodiment of the The inventive method are in the first tool unit a brush roller and in the second tool unit as plate-shaped processing tools adjustable against the workpiece surface Disc brushes used. Brush-shaped editing tools have proven themselves in practical use proven to be particularly versatile, with additional it should be noted that on the one hand the brush rollers and the plate brushes each for quite different ones Editing interventions are suitable and that to the other in addition there is the possibility of both specific for brush rollers as well as for plate brushes to use adapted bristle material (bristle trim), for more or less intensive editing to be able to generate.

In addition, advantageously still exist diverse possibilities of action in relation to the Rotary movements and the adjustment possibilities of both Brush rollers as well as the plate brushes, what from the later description of various embodiments still becomes clear.

The device designed according to the invention draws is characterized in that for at least one processing zone this device has at least one processing roller containing first tool unit and one at least one group of plate-shaped processing tools containing second tool unit provided and these tool units optionally for processing the workpiece surfaces are operable, whereby the processing roller with its outer peripheral surface in about radial direction and the plate-shaped processing tools with their outer faces roughly adjustable in the axial direction against the workpiece surfaces are.

According to a particularly advantageous embodiment of this Each tool unit has its own device Tool storage frame for arrangement and mounting of the editing tools on and it's one Quick change device for optional mutual Exchange of the various tool units provided each tool storage frame in its Shape and similar in its outer dimensions is designed so that it fits exactly in the same Sub-frame of the main device frame fixed but interchangeable. Through this If necessary, and if necessary, in rapid change very diverse or different Types of processing with optimal results can be processed, since one optimally corresponds to the desired one Machining result and the respective workpiece types adapted tool unit - because of the quick Interchangeability or interchangeability of the tool units - can be used.

Especially with this training with quick-change device a further embodiment of the invention has been found as very beneficial, after which each tool unit about their tool storage frame in the operating state firmly screwed to the sub-frame and loosened Installation and removal condition on slide rails this Supporting sub-frame supported and guided in this way is that it is from a long side of the device quickly installed and removed and thus a quick change the tool units can be made.

The overall structure of the processing device according to the invention 1 is first explained with reference to FIGS. 1 to 3, adding that there essentially - in a partially simplified form - only the device parts are illustrated to illustrate the invention be considered necessary.

This processing device 1 is used for processing of surfaces 2a of any, essentially flat Workpieces 2 (e.g. made of sheet metal, wood materials, Plastics and the like), which during their processing on a suitable transport device, for example a conveyor belt only indicated in Fig.1 3 for example in the direction of arrow 4 (Fig.2) below one or more processing tools each installed tool unit transported along become.

In the illustration in FIGS. 1 to 3 it is assumed that in the processing device 1 a first tool unit 5 is installed, in which a brush roller 6 as a processing roller or roller-shaped processing tool is arranged to be driven in rotation. How later The brush roller can be explained in more detail 6 - as known in principle - with your Outer peripheral surface in approximately the radial direction against the Workpiece surface 2a set or lifted off become, i.e. the brush roller 6 is with the entire first tool unit 5 in the direction of the double arrow 7, that is, in the vertical direction, to a sufficient extent and precisely adjustable.

The processing device 1 includes a main device frame 8, in which a main frame 9 with the help of two adjustment gears (e.g. worm gears) 10 and associated adjusting spindles 11 in the vertical direction and is therefore adjustable in height to ensure vertical adjustability or starting the respective tools (e.g. brush roller 6) according to double arrow 7 to guarantee against the workpiece surfaces 2a can. The adjusting spindles 11 can approximately in Hollow shafts of the adjustment gear 10 axially adjustable his. This axial adjustment (and thus the Height adjustment of the main frame 9 with it arranged device parts) can by any suitable Drive device happen; in this embodiment Air cylinders 12 are provided for this purpose. The axial adjustment path can also by suitable and preferably adjustable stops 13 (Fig.2) can be limited.

The axial adjustment explained above can be used to a certain extent as a double axial adjustment and thus as double height adjustment in the direction of the double arrow be carried out in such a way that in each case in the main device frame 8 built-in editing tools (Brush roller 6 or those to be explained later Disc brushes 25) on at least two adjustment paths vertically adjusted relative to the tool surfaces 2a can be, of which the first adjustment is the general Adjustability and adjustability and the second Adjustment path forms a predeterminable stroke size by which the machining tools from the workpiece surfaces 2a raised to an inactive disengaged position become. The latter can then be useful, for example may be required if workpieces 2 at a back and forth relative movement between the machining tools and machined the workpiece surfaces and the processing tools when reversing no processing in a starting position or the like Execute the workpiece surfaces, i.e. inactive should be. In this inactive or disengaged position it is generally sufficient if the tools only a few millimeters (e.g. 3 mm) from the Workpiece surfaces are lifted or removed. This lifting of the editing tools can be done automatically with the reversal of the relative movements (e.g. to Drive back). Regardless of this lifting of the processing tools around the predeterminable or The machining tools can be preset with the stroke size with the help of the adjustment gear 10 and the associated Adjustment spindles 11 via the first adjustment path with sufficiently large adjustment dimensions any general be employed or adjusted if necessary (e.g. with different workpiece thicknesses, after wear of the bristle trimmings of the processing tools etc.).

A swing frame 14 is also arranged in the main frame 9, the one at the ends by longitudinal guide pins 15 or the like in fixed guide bushings 16 in Direction of dashed double arrow 17 for one approximately across the workpiece 2 or its direction of transport stored back and forth movement according to arrow 4 is, i.e. this swing frame 14 can be a corresponding one transverse reciprocating relative movement between the workpieces 2 and the tools (e.g. roller 6). For this purpose Swing frame 14 on the main frame 9 a suitable Assigned oscillation drive 18, which u.a. a drive motor 18a, an angular gear 18b and a crank mechanism 18c can contain. Of course you could other suitable oscillation drives are also provided be such as a pneumatic cylinder or an electric cylinder.

For further explanation, first refer to FIG. 4 referred to 6, in which only the first tool unit 5 illustrated in different views is. It can be seen here that this first tool unit 5 - like any tool unit of the machining device 1 - its own tool storage frame 19 for arrangement, mounting and pivoting of the associated processing tool, i.e. in in this case the brush roller 6. In this Tool storage frame 19, the brush roller 6 is over their shaft ends 6a, 6b in two on this face Storage frame 19 hanging bearings attached down 20 rotatably mounted. That beyond the camp 20 extended a shaft end 6b of the brush roller 6 carries a non-rotatably attached drive wheel, which preferably in the form of a pulley or V-belt pulley 21 is formed. One takes into account the previous explanations for FIGS. 4 to 6 again reference to the overall representation of the processing device 1 to 3, then be first noted that this processing device 1 as an important feature a quick change device for optional mutual exchange which contains various tool units. Which also includes on the one hand, basically the tool storage frame each tool unit of the machining device 1, the tool storage frame of all tool units in their shape and in their external dimensions are of the same design and belong to the other also a sub-frame of the main device frame 8, this receiving subframe like this is executed that every tool storage frame fits exactly in it of the different tool units the processing device 1 fixed, but replaceable can be installed.

This tool storage frame 19 itself has essentially the shape of an elongated regular Rectangle of sufficient length.

If you look at it again in the aforementioned sense the whole processing device 1, then you can see in particular in Figure 2 first that the on the basis of Fig. 4 to 6 explained tool storage frame 19 in the already mentioned recording subframe which is preferably (according to this embodiment) formed by the swing frame 14 explained above is. In the illustrated in Figures 1 and 2 Operating state of the processing device 1 that the first tool unit 5 about their tool storage frame 19 firmly with the Swing frame (= sub-frame) 14 with the help of Screws 22 is permanently installed or screwed. On in this way the first tool unit 5 (as well any other tool unit that can be installed there) during of the machining company, on the one hand, directly or permanently with the swing frame 14 and the other - about this Swing frame 14 - also firmly connected to the main frame 9, so this tool unit 5 - and any other firmly connected tool unit - both the Oscillating movements (double arrow 17) of the swing frame 14 as well as the vertical adjustment or adjustment movements (Double arrow 7) of the main frame 9.

As can now also be seen in FIG. 2, the lower ones are Ends of the swing frame 14 in the form of bends 14a - pointing inwards - bent inwards, see above that they the side members 19a of the tool storage frame 19 reach under, these bends at 14a their upward-facing sides in the form of slide rails (if necessary or appropriate with sliding material pads) are trained. If now the screws 22 out the tool storage frame 19 are unscrewed and the latter or the associated tool unit 5 is in the released state, then supports this tool storage frame 19 via its side members 19a accordingly on the bends or slide rails 14a. In this released installation or removal state can the tool unit 5 or each tool unit - with support and guidance on the Slide rails 14a - from one long side (or one Front end) of the processing device 1 forth quickly each tool unit can be installed and removed exchanged for another tool unit become. A tool unit newly installed in this way supports itself after it is inserted into the receiving subframe or swing frame 14 first on the Slide rails 14a and then when they are in their exact installation position, using the Screws 22 firmly back onto the swing frame from below 14 are grown so that they can then in their Operating state in the processing device 1 located.

In the installed state (Fig. 1 and 2) this first Tool unit 5 is the V-belt pulley 21 of the brush roller 6 in the area of one end the processing device 1. Accordingly, in suitably in or on the main device frame 8 for the rotary drive of this brush roller 6 one Drive device 23 fixedly attached by a drive connection, preferably a belt drive or V-belt drive 24 with the drive wheel or V-belt pulley 21 installed in the swing frame 14 first tool unit 5 (or any other built-in tool unit) in drive connection stands. The drive device 23 or a corresponding one Drive motor can generally be customized for an overall Drive speed of the brush roller 6 designed his; however, it can be particularly useful if this drive device 23 with a speed control is equipped so that the different Machining tools with those considered to be optimal Rotation speeds (also in adaptation to different materials) can be driven. there it can also be particularly advantageous if the drive device 23 is designed so that the each processing tool used (be it a Brush roller 6 or more, be it plate-shaped Machining tools / disc brushes, as explained in more detail if necessary, with reversible direction of rotation can be driven.

A special feature of this processing device according to the invention 1 can generally be seen in the fact that one or each (if there are several of the same type and series-connected) processing zone this device 1 has at least one processing roller or brush roller 6 containing the first tool unit 5 and at least one group of plate-shaped Second machining tools Tool unit provided and these tool units optional, i.e. interchangeable for processing the workpiece surfaces 2a in the device 1 can be operated.

While now the processing device based on Figures 1 to 6 1 in connection with one interchangeable built-in or built-in, a brush roller 6 containing first tool unit 5 explained was based on the other figures described that and how a second tool unit with plate-shaped processing tools in the form of Disc brushes exchangeable in the processing device 1 can be installed.

Before going on to the different embodiments of this second tool unit is discussed first sent that in this second tool unit - regardless of which of the different embodiments - a sufficient number of plate-shaped Machining tools in the form of plate brushes 25 is provided, which are all designed in the same way, brush shafts 26 arranged substantially vertically have and accordingly about vertical axes of rotation are rotatably arranged - as in the various Recognize figures - at least by their opponents the workpiece surfaces to be machined, that is a downward facing outer face Have bristle trim 25a. In contrast is on the outer peripheral surface of the brush roller 6 - as in the Fig. 1, 2 and 4 indicated - an approximately radial bristle 6c attached.

7 to 10 in particular, let us now consider a first one Exemplary embodiment of the second tool unit 30 explained in which a number of plate brushes 25 are provided is. This second tool unit 30 has initially - as already mentioned above in connection with of the first tool unit 1 partially explained - its own tool storage frame 19 'for the arrangement and holding the associated processing tools, So the plate brushes 25 on. This tool storage frame 19 'in turn does not form only one Part of the associated tool unit, i.e. the second Tool unit 30, but also part of the already Quick change device of the Processing device 1 to an optional mutual Exchange of the different tool units to enable. Like a comparison of the graphic Representations in Figures 4 to 5 of the first tool unit 5, on the one hand, and Fig. 7 to 9 for this second tool unit, on the other hand, recognize well can, this tool storage frame 19 ' the second tool unit 30 in the form of an elongated one regular rectangle, not only its shape, but also its external dimensions are the same or the same size as those of the tool storage frame 19 of the first tool unit 5. This tool storage frame 19 '- how 8 and 10 in particular clarify - pronounced and longitudinal members 19'a which can be freely gripped from the outside on, so that this tool storage frame 19 'in turn fits exactly into the same mounting subframe, So the swing frame 14 of the main device frame 8 fixed but interchangeable, in exactly the same way as above in Connection with the tool storage frame 19 of the first tool unit 5 (in particular with reference to FIG. 2) in the individual has been explained, what to avoid be referred from repetitions.

In the first illustrated in FIGS. 7 to 10 Embodiment of the second tool unit 30 is provided that the plate brushes 25 on their as brush shafts 26 trained rotating shafts individually in the tool storage frame 19 'for example with the help of Rolling bearings 27 in the manner illustrated in Fig.10 are rotatably mounted. Two adjacent to each other Brush shafts 26 are on their plate brushes 25 opposite shaft ends 26a by a drive connection connected to each other with the drive first embodiment of the second tool unit 30 by a belt drive, preferably one Toothed belt drive 31 is formed. These are - as in particular 7 and 10 show - on the upper shaft ends 26a of the brush shafts 26 generally each two corresponding toothed belt pulleys 31a axially directly one above the other or a corresponding double disc non-rotatably attached.

So that the plate brushes 25 of this second tool unit 30 with the same drive device 23 as that Brush roller 6 of the first tool unit 5 driven are when this second tool unit 30 is operational is installed in the swing frame 14, is on the associated Tool storage frame 19 'at the same end as with the tool storage frame 19 of the first tool unit 5 again an identical drive wheel or a similar V-belt pulley 21 rotatably supported, the one on the belt drive (V-belt drive) 24 with the drive device 23 (see Fig. 2) and on the other hand via an angular gear 32 with the toothed belt drives 31 for the plate brushes 25 is connected to the drive. This angular gear 32 is thus - as shown in Figure 7 in particular - between the associated V-belt pulley 21 and the corresponding first tool-drive connection, i.e. the neighboring one Toothed belt drive 31 arranged, on this connection a further toothed belt drive 32a is provided (Fig. 7 and 9).

Based on the purely schematic partial plan view of the second tool unit 30 is briefly on the order the plate brushes 25 received. In this Fig. 11 shows that in at least one Arrange group and at least two transverse rows together Disc brushes 25 - viewed in plan - about are staggered to each other and that they are at least in relation to the workpiece transport direction (Arrow 4), but preferably also, as shown, overlap each other in the transverse direction. This evenly overlapping arrangement the plate brushes 25 can do this among them workpiece 2 transported through on its surface 2a of the plate brushes 25 or their brush trimmings 25a can be optimally processed. This brush plate assembly basically also applies to the following further described embodiments the second tool unit.

From the second embodiment of the second tool unit 30 is only a top view similar to FIG. 9 illustrated in Fig.12. The main difference between that explained with reference to FIGS. 7 to 10 first embodiment and this second embodiment of the second tool unit 30 in that in this second embodiment Drive connections between two adjacent ones Brush shafts 26 each through a gear transmission 33 is formed, each on two adjacent to each other Brush shafts 26 attached spur gears 33a and at least one reversing spur gear arranged between them 33b contains. Otherwise, this will also be the second Embodiment of the second tool unit 30 all Gear 33 in turn from the V-belt pulley 21 and the bevel gear 32 driven, the same as in Figures 7 and 9 on one Front end of the associated tool storage frame 19 ' are arranged, between angular gear 32 and the adjacent gear transmission 33 a similar adapted gear transmission 33 'can be provided. The tool storage frame 19 'is exactly the same here executed as he explained with reference to Figures 7 to 9 is.

While previously two typical with reference to FIGS. 7 to 10 and 12 Embodiments have been explained how in the second tool unit 30 all disc brushes 25 driven together via their brush shafts 26 13 to 16 is a third Illustrated embodiment in which each plate brush 25 assigned a separate drive motor 34 is, it is preferred, each drive motor 34 to be equipped with a separate speed control. The individual plate brushes 25 can on the downwardly projecting ends of the motor drive shafts 34a be attached so that the plate brushes 25 then again driven to rotate about vertical axes of rotation can be. Also in this third embodiment are the disc brushes 25 with their single drive motors 34 in its own tool carrier frame 19 'recorded and supported, the shape and External dimensions to those of the above based on approximately the Fig. 7-10 described tool support frame 19 'correspond.

Through this use of single drive motors 34 for the plate brushes 25 result in a wide range of variations, when editing various Workpieces. So the plate brushes 25 can all with of the same kind or individually or in groups with different ones Rotational speeds are driven. In addition, it can be advantageous if these plate brushes 25 are then infinitely adjustable Rotational speeds are driven, it also can also be an advantage if these plate brushes 25 optionally in one or the other direction of rotation can be driven, namely all plate brushes 25 each in one or the other direction of rotation or directed against each other individually or in groups. There is also the possibility for example in adaptation to the respective Workpiece width or to several arranged side by side Workpieces, all processing tools individually or to control and drive in groups.

Especially when using single drive motors 34 for the plate brushes 25, but possibly also when used a common drive device for everyone Disc brushes 25, there is also the possibility Disc brushes 25 individually, in groups or together against the workpiece surface 2a. This is For example, advantageous if the bristle trim 25a of the plate brushes worn to a certain extent is, i.e. there is the possibility of the plate brushes 25 according to their respective wear by an adjusted Readjustment.

In summary it can be said again that the surfaces according to this embodiment of the invention 2a of workpieces 2 in one and the same processing device 1 optionally by means of at least one Processing roller, preferably a brush roller 6 containing first tool unit 5 or - in exchange to do this - by means of a group of plate-shaped Processing tools, preferably disc brushes 25 containing second tool unit 30 machined become. It is then in each case corresponding Way, the brush roller 6 approximately in its radial Direction against the workpiece surfaces 2a, while the plate brushes 25 approximately in their axial Direction against the workpiece surfaces 2a are, in each case according to the double arrow 7 1 and 2. The workpieces 2 are then during processing their surfaces 2a with the help of Transport device 3 in the longitudinal direction under the processing tools, So the brush roller 6 or under transported along the plate brushes 25. Are there then the workpieces 2 are sufficiently firm or stationary deposited on the transport device 3, with it With the help of this transport device 3 continuously as required, batchwise or reversible relative to the processing tools are transported.
