Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a machine for deburring thin sheets, plates or the like with a rotating wire brush, which deburrs at least one longitudinal edge of the workpiece as seen in the feed direction of the workpiece. It relates to a type in which a plurality of brushes driven in opposite directions are arranged side by side along the line.

Such a machine is known from GB 1488974. In this case, for each longitudinal line of the workpiece, viewed in the feed direction of the workpiece to be machined, two mutually adjacent bowl-shaped brushes are provided. The rotational axes of these brushes are located perpendicular to the direction in which the workpiece is fed, so that machining can be performed on the end faces of the brushes. In this case each brush has its own drive motor.

From US Pat. No. 3,400,449 an apparatus is known for preparing the surfaces of sheet metal or the like for welding operations. In this case too, the brush engages the edge of the workpiece. This device uses a circular brush whose axis is parallel to the edge of the workpiece, and is designed to work around its outer periphery. In this case, adjacent brushes are each offset in height and driven in opposite directions, but each has its own drive motor.

The object of the invention is as stated at the outset, so that the area to be deburred of a board, sheet metal or the like is treated as uniformly as possible and that fewer drive motors are required for the brushes than for the brushes. The objective is to provide a machine of a new type.

This task requires that the brush has at least one common
The problem is solved by the fact that the brushes are arranged on shafts extending parallel to the feed direction and that mutually opposite directions of rotation are obtained for the respective adjacent brushes via reversing gears, intermediate gears or the like. Ta. Thus, although the brushes are arranged on a single axis, each adjacent brush can be rotated in opposite directions. In this case only one drive motor can be used to drive the brushes in at least one direction of rotation or all the brushes on one shaft.

A particular advantage of such an arrangement is that, especially when the sheet metal or plate is relatively thin, the brushes acting at the outer periphery in one direction of rotation simultaneously deburr the lower edge of the sheet metal or plate in the opposite direction. The brush deburrs the upper edge. In other words, the sheet metal or plate can penetrate into the flexible circumferential region of the brush, so that, depending on the direction of rotation, the brush mainly processes the edges of the workpiece that lie ahead in the direction of rotation. Therefore, in this case 1
There is no longer a need to turn the workpiece over after two working steps in order to machine the raw edges of the workpiece.
Furthermore, any number of brushes can be arranged one after the other, since each brush does not have its own, space-consuming and structurally complex drive. The invention thus makes it possible to simultaneously deburr the upper and lower edges in a single working step.

The intermediate transmission can be constructed as a belt, toothed belt or gear transmission and can be branched off from a driven intermediate or transmission shaft.

Furthermore, in order to machine the parallel edges of a sheet metal, the brushes are arranged opposite each other, with the respective adjacent brushes being driven in opposite directions, even when the workpieces are relatively short. Also, the workpiece being sent is perfectly guided. This is because in this case approximately the same number of opposing force components act on the workpiece. Furthermore, it has been found to be advantageous in this case to arrange any number of brush pairs of oppositely driven brushes one after the other on the same shaft.

A particularly advantageous embodiment of the invention is characterized in that the brush in one direction of rotation is non-rotatably connected - for example via a key - to the driven shaft holding it, whereas the brush in the other direction A brush driven in the rotational direction is rotatably supported on the shaft. Thus, the brushes in one direction of rotation rotate together with the shaft holding them, while the brushes located between these brushes are each driven in the opposite direction via the intermediate gear mentioned above. In this embodiment with the brushes arranged non-rotatably on the driven shaft, it is therefore advantageous if the intermediate transmission is also branched off from the driven transmission shaft. however,
It is also possible to provide a common drive motor and a transmission for the shaft and the transmission shaft.

Furthermore, the modified embodiment of the present invention is characterized in that all the brushes are arranged on a hollow shaft, and a transmission shaft extending parallel to the inside of this hollow shaft is rotatably supported, and the hollow shafts are rotatable in opposite directions. between the brushes, at least one opening for an intermediate transmission, in particular a gear transmission or the like. Such an arrangement makes it possible to save even more space since parallel transmission shafts are eliminated. In this case, the hollow shaft and the transmission shaft may be driven respectively.

As already mentioned in the embodiment with two parallel shafts, in this case a shaft holding the brush in one direction of rotation in a non-rotatable manner and a transmission shaft, in particular a hollow shaft and a transmission shaft located inside it. They can also be driven by a single common drive motor via a clutch, transmission part or the like. However, in this case too, if a large number of brushes are arranged one after the other and a large force is required, each shaft can also be provided with its own drive motor.

Also, brushes driven in opposite directions are arranged on a common shaft, with one direction of rotation of the brush being non-rotatably coupled to this shaft and the other brush being rotatably supported on this shaft. In a variant embodiment, intermediate gears supported on the shaft and/or the housing are arranged between the respective counter-driven brushes. In this case, for example, friction wheels with stationary bearings and preferably connected to the housing can be provided on opposite sides of the brushes to be driven in the opposite direction. In this case, for example, a lamella or the like is arranged between two oppositely driven brushes, and an opening is provided in this lamina or the like between the sides of the brushes, in which the friction It is possible to arrange the car and its bearings so that they protrude on both sides. Between the two brushes, in each case a plurality of friction wheels, preferably two or three, whose axes are arranged radially, are uniformly arranged in a circle concentric with respect to the outer circumference of the brushes and the brush axis. It is advantageous to have In this way, the friction wheel acts evenly on the brush boss,
The rotation of one brush is transmitted to the adjacent brush by changing the direction of rotation.

Another embodiment of the invention is characterized in that a bevel gear transmission is provided between each two oppositely driven brushes, and at least one bevel gear meshing with the bevel gears on the brushes is stationary. Preferably, it is connected to the machine casing. In this case, in order to achieve as uniform a transmission of force as possible, the bevel gear connected to the brush must have at least two
It is advantageous to mesh the two bevel gears. One bevel gear is connected to the casing via a tension bolt or the like, and at the same time engages a stationary ring which is supported via a ball bearing on a common shaft. This ring holds another bevel gear. In this case, the angle of the teeth of this bevel gear can be selected as required. It is therefore even possible for the gearwheel engaging between the brushes to have spur teeth.

In some of the embodiments described above, an intermediate transmission or similar element can be placed in a cutout in the brush end face, so that only a narrow gap is formed between the brushes. This provides good guidance of the workpiece when feeding it. However, it is also possible to arrange a guide stop for the workpiece in at least one intermediate space between the brushes. This is advantageous if such an intermediate space between the brushes is required for the engagement of an intermediate transmission.

Furthermore, the efficiency of the machine of the present invention is determined by two parallel
The spacing can advantageously be increased in that the adjustable shaft is provided with counter-rotatable brushes. This makes it possible to process parallel edges of the workpiece at the same time or to arrange the projected contours of the brushes on parallel axes to intersect when viewed from the front. In this embodiment, a wedge-shaped space is formed between the two axes, through which one longitudinal edge of the workpiece passes. Such an arrangement is advantageous if both edges of the workpiece edge are to be machined simultaneously in one operation, even though the workpiece is relatively thick.

In the embodiment described above with two shafts with oppositely driven brushes for one longitudinal edge of the workpiece, it is also possible to have a respective coaxial brush for each longitudinal edge of the workpiece. In this embodiment as well, it is advantageous for the brush that loads one of the edges of the workpiece, preferably the upper edge of this workpiece, to have a higher rotational speed than the brush that loads the other edge. It is. In many cases, for example in the case of folded surfaces, there are severe burrs on one side which can only be removed with rapidly rotating brushes. A continuously adjustable drive can be used as the drive.

According to another embodiment of the invention, all the brushes are each rotatably mounted on a stationary shaft;
The shaft each has at least one transverse hole between two counter-rotatable brushes, in which a bearing pin is held which meshes with a bevel gear on the brushes arranged on both sides. or with a holder for a friction wheel which loads the sides of the brushes, one brush preferably arranged at the end of the brush row being connected to a drive for rotating it. ing.

Furthermore, it is advantageous if the at least two counter-driven brushes in each case are axially pressed against each other by at least one spring, preferably a disc spring. This is particularly advantageous if a friction wheel is used as the intermediate transmission.

This means that the invention allows adaptation to different workpieces during deburring, but in any case only the edges or narrow surfaces to be deburred are loaded with the brush. In this case both edges of one of the edges of the sheet metal are brushed or deburred. The machine according to the invention is therefore suitable for deburring small quantities of sheet metal of different dimensions. In this case only one row of brushes is provided, along which the workpiece is guided, or two such rows of brushes are provided, between which the workpiece is guided and a longitudinal cutting device for cutting the coil. It is possible to collaborate with

The invention will now be explained with reference to the drawings. The machine 1 described below, which is a structurally different embodiment of the idea of the invention, is used for deburring the edges of a sheet metal or plate 3 using rotating wire brushes 4 and 5. In both embodiments, a plurality of brushes 4, 5 are provided adjacent to each other in the feeding direction of the thin plate 3 and the edge 2 of the thin plate to be deburred. The axes of these brushes 4 and 5 are arrows
It extends parallel to the feed direction indicated by Pf ₁ ,
By means of these axes, the brush 4 is driven in the opposite direction relative to the brush 5. The brush 4 in one direction of rotation therefore deburrs the upper edge of the sheet edge 2 in the direction of rotation indicated by the arrow Pf ₄ in FIG. 1, whereas the brush 5 in the other direction deburrs the lower edge. From thin plate 3
The lower edge is deburred as it rotates against the surface. In this case, the brushes 4, 5 have the same diameter in both embodiments.

Furthermore, the respective adjacent brushes 4, 5 - the brushes forming a brush pair - have opposite rotational directions. However, in Fig. 12, there are four brushes 4,
In the case of a group of 5 brushes, both outer brushes 4 can be driven in one direction and the other inner brush 5 can be rotated in the other direction.

The guide or support for the workpiece or sheet metal 3, preferably the surface of the table 6, can be arranged as a diameter extension of the brushes 4 and 5 or parallel to it. It can be seen in FIG. 3 that in this embodiment the lamina 3 is located in the horizontal diametrical extension of the brushes 4 and 5 and is itself arranged so as to be guided horizontally. In this case, the table 6 is adjustable in height relative to its holder 7, so that the lamina 3 is brought into contact with the brushes 4 and 5 in a position arranged parallel to the horizontal diameter. ing. In this case, downward adjustment of the table 6 becomes a problem.
As a result, the brush 4 rotating against the thin plate 3 from above is made to act more strongly on the thin plate 3. As a result, the thin plate 3 is held more securely on the guide or table 6. Furthermore, in this case the upper edge of the sheet metal edge 2 is machined more strongly. This is advantageous in the case of sheet metals 3 which are cut by punching and in which the sheet metal edges located lower in the direction of the punching cutter protrude to a greater extent with respect to the sheet metal surface.
It is expedient for these more prominent edges to be directed upwards on the table 6 so that they can be fully captured by the strongly acting brush 4.

In addition to the height adjustment of the table 6, a lateral adjustment can be carried out using an eccentric 8 and a lever 10 which can be fixed in different holes 9. This adjustment possibility is shown in the embodiment of FIG. 5, but can be implemented in the same way in other embodiments. In particular, this lateral adjustment allows the table 6 to be adjusted later to a retracted brush contour when adjusting the height of the table 6. Furthermore, in the case of a machine 1 with parallel brush rows for simultaneously machining parallel sheet edges, the lateral adjustment also allows adjustment for workpieces of different widths.

According to the invention, brushes 4 and 5 with different rotational directions can be arranged on the same axis. This axis is designated by the reference numeral 11 in the embodiments of FIGS. 1-3. Similar axes are also provided in other embodiments and are mentioned separately in each case in the description.

The brush 4 in one direction of rotation is connected to the shaft 1 with the key 11a.
1, while the brush 5, which is driven in the opposite direction, is supported on the shaft 11 via a rolling bearing 11b and has a suitable drive device which varies depending on the embodiment. There is. Figures 1 to 5
In the embodiment shown, a belt or toothed belt drive 12 having a belt 13 and two belt pulleys 14, 15 is provided as a drive for the brush 5. The belt pulley 14 is seated on the transmission shaft 16, whereas the belt pulley 15 is connected to a bush 17 which holds the brushes 5 and is mounted on a rolling bearing as already mentioned above with respect to the shaft 11. or is integrally combined with it. This is particularly illustrated by the brushes 4, 5, which are shown in cross-section in FIG.

By means of this drive, a spacing or intermediate space 18 is created between oppositely driven adjacent brushes 4 and 5 of a brush pair. or,
A similar spacing or intermediate space 19 is provided between each pair of counter-rotating brushes 4, 5. In this embodiment, a stopper 20 is engaged in the intermediate spaces 18, 19, against which the thin plate 3 is placed against during processing. This prevents the lamina 3 from being pushed too deeply into the brushes 4, 5, which could be damaged or prematurely worn out.

In FIGS. 2 and 3 an embodiment is shown in which two rows of parallel brushes 4, 5 are provided facing each other at the same height. In this case, the distance between the two rows of brushes 4, 5 can be adjusted by means of a spindle 22 and a nut 23 arranged on the machine frame 21. The table 6 is in this case divided into two parts, one part is connected to the spindle 22,
The other part is connected to a nut 23.

The lateral stops 20 can be constructed as rollers 24 and driven to facilitate feeding.
In FIG. 3, drive is provided by the shaft 25 via a bevel gear 26 and a shaft section 27 which carries the roller 24 at its end. However, the conveyance of the sheet metal 3 can also take place in other ways, for example by conveyor belts or the like.

4 and 5, counter-rotating brushes 4, 5 are supported on parallel shafts 28 and 29, coaxially on the one hand and at different heights on the other hand; An embodiment is shown in which the brush contours partially intersect when viewed from the side. In this case, the shafts 28 and 29 are located vertically one above the other.

The shaft 29 is supported on a rocker 30, by means of which the mutual distance between the shafts 28 and 29 can be varied. Correspondingly, the degree of intersection or bite of the brushes on both axes 3
1 is expanded or contracted. FIG. 5 shows that between the respective brushes 4 and 5 between the two shafts 28 and 29, the sheet metal 31 to be deburred is well guided and, in particular, when the sheet metal 31 is a relatively thick sheet metal. It is clear that a bite 31 is provided in which the brush pair hits the edge of the side edge of the lamella 3 at an effective angle.

In the embodiment of FIG. 5, each brush hits the edge at an angle of approximately 45 DEG to the top or bottom surface of the sheet, so that the edges are effectively deburred. In this case, on the upper shaft 29 there are arranged the same number of brushes 4, 5 which rotate in opposite directions, and on the lower shaft 28 there are likewise the same number of brushes 4, which rotate in opposite directions. , 5 are provided. This means that the upper burrs on the sheet metal 3 are removed both from above by the brushes 5 and from the sides by the brushes 4 acting from below. Similarly, the lower burrs are processed by the brush 4 from below, and by the brush 5 from the side or above. This measure prevents further burrs from being created by deburring. This is useful when removing significant burrs, particularly prominent punching burrs. Also, kinematically, this procedure reduces the acting and reaction forces on each axis 28, 29, so that the forces that cancel each other out tend to be removed with different strengths. Having acted on the burr, the sheet metal 3 assumes a perfectly stable position during the deburring process.

There are various possibilities for driving these brushes 4, 5. Only one possibility is shown in FIGS. 4 and 5. In this case, the brush 4 is driven by a separate motor to rotate to the left on shafts 28, 29, whereas the brush 5 is driven to rotate to the right via a transmission shaft 16 and a belt drive 13. driven by In this case both axes 2
8, 29, or one of the shafts can be arranged on the rocking body 30.

If it is desired to save one motor in driving the shafts 28 and 29, the connection between the shafts 28 and 29 can be replaced by a toothed belt drive or a belt drive, as indicated schematically at 33 in FIG. This can be done by means of a variable shaft transmission in the form of a device. Depending on this connection, other rotational speed combinations are possible. This combination of rotational speeds can be implemented by means of a crossed belt drive and a gear reversing drive. What is important in each configuration is the number of brushes to be driven. In other words, if the number of brushes is small, a reversing drive can be provided if this is more advantageous than using a separate motor. In the case of machines with four brushes it is advantageous to use separate motors. This is because in this case the entire reversing drive and transmission can be saved.

In FIG. 6 an embodiment is provided in which the brushes 4 and 5 are provided with two parallel axes driven in opposite directions. In this case all brushes 4, 5 are arranged on at least one hollow shaft 34. Inside the hollow shaft 34 is a transmission shaft 3 extending in parallel.
5 is rotatably supported via a bearing 35'. In the region between the counter-rotating brushes 4, 5, the hollow shaft 34 has a recess 36 for an intermediate gear 37. The hollow shaft 34 is supported by the machine frame 21 via a bearing 34'.

In FIG. 6, the first intermediate transmission device 37 is
A gear transmission device is provided in which a gear 38 is non-rotatably attached to a transmission shaft 35 with a key 39. In the area of the recess 36, a further gear 40 is rotatably mounted on a shaft 41 which is fixed to the hollow shaft 34 in the area of the recess. This gearwheel 40 meshes with a ring gearwheel 42 with corresponding teeth, which is fixedly connected to the brush 5 which is rotatably mounted on the hollow shaft 34 via a rolling bearing 43 .

In this case, the hollow shaft 34 and the transmission shaft 35 are each driven. This can be done by each with its own drive motor or, as shown in FIG.
It can also be done via. By selecting the rotational speeds of the hollow shaft 34 and the transmission shaft 35, the brushes 4 and 5 rotating in opposite directions can be given the same or different rotational speeds.

In the embodiment shown in FIGS. 7 to 9, the oppositely driven brushes 4, 5 are arranged on a single common shaft 47. In this case as well, the brush 4 in one direction of rotation is connected to the shaft 4 via the key 11a.
The other brush 5 is rotatably supported on a shaft 47 via a rolling bearing 11b. Between the two oppositely driven brushes 4 and 5 of a brush pair there is provided an intermediate transmission, which is supported on the shaft 47 and/or on the machine frame or casing 21 and will be described in more detail below. There is.

In the embodiment shown in FIG. 7, a bevel gear transmission is provided as the intermediate transmission. In this case, at least one bevel gear 49 meshing with the bevel gear 50 of the brushes 4 and 5 is fixedly connected, that is to say to the machine frame or housing 21.

Furthermore, in FIG. 7, at least two bevel gears 49 are connected to the brushes 4, 5 to obtain a more effective power transmission and to avoid bevel gear tilting and the like. It meshes with 50. In this case, one bevel gear 49 is connected to the housing or machine frame 21 via a tension bolt 51 and at the same time has a ball bearing 5 on a fixed, common shaft 47.
2 on the supported ring 53. This ring 53 holds another bevel gear 49.
This bevel gear 49 is fixed to a ring 53 via a screw 54. Further, by screws 55 passing through the brushes 4 and 5 parallel to the shaft 47, bevel gears 50 are connected non-rotatably to the brushes 4 and 5, respectively.
are fixed to mutually facing sides of the bosses of the brushes 4 and 5. Furthermore, the bevel gear deflection transmission device 48
and tensile bolt 51, brushes 4 and 5
While there is a stopper of 20 between each,
The gap 56 between the two brush pairs is chosen to be as narrow as possible.

The intermediate transmission, in particular the intermediate transmission 37 of the embodiment shown in FIG. ing. This avoids a stop between adjacent brushes 4 and 5, for example in FIG.

In the embodiment of FIGS. 8 and 9, a friction wheel 58 is arranged in a recess 57 in the mutually facing sides of the brushes 4 and 5, which are driven in opposite directions.
A bearing 59 of this friction wheel 58 is connected to the casing 21 .

In the embodiments of FIGS. 8 and 9, two oppositely driven brushes 4 of each brush pair are used.
A thin plate 60 is arranged between and 5. This thin plate 60 is attached to the sides or notches 5 of the brushes 4 and 5.
7 has an opening 61 within which the bearing 59 of the friction wheel 58 is arranged so as to protrude to both sides. In this case, the bearing 59 of the friction wheel 58
a fixed shaft which is threadedly connected to the edge 62 of the opening 61, on which the friction wheel 58 is rotatably mounted.

As shown in particular in FIG. 9, between the two brushes 4 and 5 there are in each case a plurality of friction wheels, namely three friction wheels 58 in this embodiment, which move the shaft or bearing 59 in the radial direction. are uniformly arranged on a circle concentric to the brush outer circumference. This allows a corresponding type of force to be transmitted. What is important in this case is that the at least two counter-rotationally driven brushes 4 and 5 are pressed together axially by at least one spring, in this example a disk spring 63, so that the frictional forces are This means that information is being communicated well.

When the shaft 47 is rotated in the embodiment of FIGS. 8 and 9, the non-rotatably connected brush 4 is carried away without difficulty. This causes a rotation of a friction wheel 58 which is itself rotatable but does not change its position, by means of which the brush 5 , which is rotatably mounted on the shaft 47 , is moved in the opposite direction to the brush 4 . can be rotated.

In the embodiment shown in FIG. 10, all brushes 4 and 5 are each rotatably supported on a stationary shaft 64 via rolling or ball bearings 11b. Between each of the two counter-rotatable brushes 4, 5, the shaft 64 has at least one holding part, in this example a transverse bore 65, into which a bevel gear 67 is inserted. A bearing pin 66 having a diameter is retained. This bevel gear 67 meshes with bevel gears 68 arranged on the brushes 4, 5 on both sides. This arrangement corresponds to a certain extent to the embodiment of FIG. However, in this case an external connection to the machine frame or casing can be avoided. Furthermore, in this case at least the first brush 4 arranged at the end of the brush row is connected to a drive for rotating it. This drive is formed by a spur gear 70 and a further transmission part 71 acting on it.

The embodiment shown in FIG. 10 has the advantage that, in place of the bevel gears 67 and 68 provided in FIG. It can be easily combined with the embodiments shown in FIGS. 8 and 9.

In FIG. 12, an embodiment is shown in which the drive motor 44 drives brushes 4 and 5 which are driven in opposite directions via a belt drive 72 and directly drives the transmission shaft 16. In this case, on the shaft 11 there is first a non-rotatable brush 4, then a second rotatable, counter-driven brush 5, and then, for example, two non-rotatably coupled brushes 4, etc. is located.

According to the invention, a deburring machine 1 is obtained in different embodiments in which both edges of one of the longitudinal edges of the sheet metal can be processed in one working step without the need for turning the sheet metal over again. Due to the alternating arrangement of the brushes with different rotational directions, a uniform force is applied to the workpiece without the need for a drive motor for each brush. This results in hazard-free work.

Note that the individual features and configurations described in this specification can be applied individually or in arbitrary combinations.
