Description
Technical Field
The present invention relates to a method for producing an elongated brush with an elongated brush body and a brush drill and packer for carrying out the method.
In particular, the invention relates to a method and a machine in which an elongated brush body is fixed to a holder which in turn is fixed to a turntable rotating about a central axis.
Background
Such rotary disc drills and packers for brushes have long been known in principle. The advantage is that there are a plurality of holders on the turntable for accommodating the brush body and rotating about the central axis, wherein a plurality of stations are provided on the circumference, i.e. supply and/or removal stations for the brush body and the finished brush; a drilling station in which holes are drilled in the brush body; and a stuffing station adjoining this, in which bristle bundles are inserted into the pre-drilled holes and fixed therein by means of anchors, i.e. by means of bent coils or platelets made of flat wires.
Although brush bodies exist which, when injection molded, already obtain holes for anchoring the bristle bundles, these holes are essentially parallel to each other and oriented in the demolding direction. However, it is important, especially in the case of household brushes and brooms, that the bristle bundles are not all parallel, but rather that it is possible to have inclined bristle bundles especially at the edges of the brush body. For this reason, holes are drilled separately for such brushes, i.e. for brushes which are not toothbrushes and not nail brushes in particular and are commonly referred to as household brushes and brooms.
Since the so-called hole area has a large number of holes arranged side by side, in the drilling station and thereafter in the filling station the brush body is moved stepwise further relative to the drill bit or the filling tool in order to be able to drill or fill the holes in sequence. The orientation of the brush body relative to the boring tool and the setting tool is in this case partially very different from the other bores in order to be able to achieve a bore orientation. Thus, the holder can be moved in at least two spatial directions with precision between the respective drilling and packing strokes at a high speed. In order to be able to provide a very powerful machine as a whole, the mass of the movement should be as small as possible.
The rotating disk, also called a drum, rotates about its central axis, and the brush body is oriented in the circumferential direction, i.e. in the direction of rotation of the rotating disk, by means of its longitudinal axis in the prior art. Machines of this type with such brush body orientation have gained acceptance in the marketplace. There are in part two drilling stations and two stuffing stations to increase throughput. In the case of small brushes, 1000 drilling and packing procedures per minute can be achieved, and in the case of larger brushes and brooms, the length of the body is at least about 400mm, which cannot be achieved.
Disclosure of Invention
The object of the present invention is to provide a method for producing an elongated brush, by means of which the brush drilling and packing machine can be operated at a higher cycle rate and is constructed compact. The brush drilling and stuffing machine according to the invention should achieve the same advantages.
The method according to the invention for producing an elongated brush with an elongated brush body is characterized by the following steps:
a turntable is provided, which rotates around a central axis and on an outer area of which a plurality of holders are provided in succession in the direction of rotation,
a drilling station and a stuffing station following in the rotation direction are arranged,
the elongated brush body is fixed to the holder such that the width direction of the brush body is oriented in the rotational direction,
rotating the turntable, causing the holder to move into the drilling station,
a plurality of holes are drilled into the brush body, wherein the brush body is moved in the width direction between the drilling processes by pivoting the holder about two parallel, spaced-apart axes of rotation, and
rotating the rotary disk to move the drilled brush body into the stuffing station, and
the bristle tufts are stuffed into the drilled holes by means of anchors, wherein the movement of the brush body in the width direction between stuffing processes is performed by pivoting the holder about two parallel, separate axes of rotation.
The method according to the invention ensures an extremely compact turntable, wherein the holders can be at a very small distance from the central axis of the turntable, so that the moving mass is small. This is achieved in particular as follows: the elongate brush bodies can be said to be oriented substantially parallel (depending on the orientation of the brush bodies relative to the so-called aperture region). The smaller width of the brush body and its aperture area relative to the length causes: despite the considerable length of the brush body, the brush body can still be arranged close to the central axis, in particular in the case of a broom. Another important factor for achieving such an arrangement of the brush body close to the central axis derives from the movement of the holder in the drilling and stuffing station for orienting the brush body in the width direction. For this purpose, the individual holders are not driven via at least one linear movement and one linear drive, but only via two independent, parallel, independent rotational axes which are spaced apart from one another and are realized by their own drives. The axes of rotation themselves require little space in the width direction, but their drives can be positioned away from the holder. The orientation of the brush body and the drive in the width direction via the two axes of rotation thus complement one another perfectly in a coordinated manner. The width direction is the circumferential direction, i.e. the rotational direction and the counter-rotational direction of the turntable.
The drilling process and the plugging process are each a single stroke of a corresponding tool by means of which the hole is drilled or plugged.
It is of course possible to arrange a plurality of drilling and loading tools side by side in the drilling or loading station in order to be able to work simultaneously on the same brush body or on different brush bodies.
According to one variant of the invention, the holder is moved in the longitudinal direction about the other axis of rotation by moving the holder linearly in the longitudinal direction and tilting the holder in the longitudinal direction during drilling and tamping. By means of this movement along a straight line, a large hole area can be achieved in the longitudinal direction. By pivoting the holder, the brush body is tilted in the longitudinal direction, so that the borehole can also be tilted along this axis.
The axis for pivoting the holder for movement, more precisely for pivoting in the longitudinal direction, is in particular tangential to the circumferential direction or lies in a radial plane (a plane perpendicular to the central axis of the turntable).
The compactness of the machine can be improved if the pivoting movement is performed in the longitudinal direction by moving a lever extending in the width direction in the rotation shaft for pivoting. Via the lever, the movement is transmitted by the electric drive in the direction of the holder or via the corresponding link to the holder, so that the corresponding drive can be positioned away from the holder and thus away from the brush body. The arrangement or extension of the rod in or by the rotation shaft ensures, on the one hand, a high compactness, while, on the other hand, the mass of the movement is very small and, furthermore, is close to the central axis.
A screw (which also includes a ball screw) or a rack can be used as a rod, for example.
As described above, there are two rotational axes for the movement in the width direction, hereinafter referred to as a first rotational axis and a second rotational axis. The first axis of rotation is for example the central axis of the turntable, so that the corresponding drive of the turntable has a dual function. Furthermore, this embodiment has the advantage that the second axis of rotation and the first axis of rotation can have a relatively large distance from one another, which simplifies the positioning of the motor for the second axis of rotation, so that the second axis of rotation as a whole can be positioned closer to the central axis than in the prior art.
Further improvement in compactness is achieved if the second rotation axis for movement in the width direction and the rotation axis for movement/pivoting in the longitudinal direction do not intersect each other even if the aforementioned lever does not extend through the rotation shaft. For tilting movements about two rotational axes, a second rotational axis and a rotational axis for the longitudinal direction, it is advantageous if the two rotational axes intersect. However, this causes an increase in the installation space in the radial direction with respect to the central axis.
In this case, it is advantageous if the axis of rotation for movement/pivoting in the longitudinal direction is radially further from the central axis than the second axis of rotation, wherein the minimum distance of this axis of rotation from the central axis is defined as the distance of the axis of rotation for movement/pivoting in the longitudinal direction.
The movement of the holder in the longitudinal direction can be performed by the movement of the turntable, i.e. not by providing linear guiding means on the turntable, which in turn increases the construction space of the turntable and its mass. In particular, the turntable does not move alone, but rather together with the base, on which the turntable is fixed.
The method according to the invention is provided in particular for manufacturing brooms having an aperture area of at least 100mm in length.
The invention also provides a brush drill and packer for carrying out the method according to the invention, the brush drill and packer having:
a turntable rotating around a central axis, a plurality of holders sequentially arranged in a rotation direction being provided on an outer area of the turntable,
a drilling station and a stuffing station following in the direction of rotation,
an elongated brush body fixed in the holder, wherein the brush body has a longitudinal direction and a width direction, and the brush body is arranged in the holder such that the width direction is oriented in the rotational direction,
wherein the holders are each mounted for movement in the width direction about two parallel axes of rotation during drilling and tamping, said holders being provided with separate rotary drives.
The advantages associated therewith are also highlighted with reference to the method detailed previously in relation to the concept according to the invention.
A holder for movement/pivoting in the longitudinal direction during drilling and tamping is supported on the rotational axis and is capable of linear movement. By pivoting in the longitudinal direction, the longitudinal end of the brush body moves axially forward and backward on a circular track in the longitudinal direction with a movement component.
Such linear movability can be configured such that all holders are moved together by a common drive.
In this case, a variant consists in that the rotary disk can be moved linearly, in particular by moving its base, to move all holders linearly in the longitudinal direction. This reduces the effort required for supporting the turntable relative to the base, since this support furthermore does not have to have a linear support.
Another variant of the invention proposes that the axis of rotation for the width movement comprises a mechanical rotation axis through which the driven rod extends, which produces the pivoting movement of the holder about the axis of rotation for movement/pivoting in the longitudinal direction.
The rod can be a screw or a rack as set forth above in connection with the method according to the invention.
Further reduction of the kinematic effort for driving in the longitudinal direction results from the following: the axis of rotation for movement in the width direction comprises a rotation shaft, which has been mentioned briefly before, through which the driven rod extends or in which the driven rod is supported, wherein the axis of rotation for movement/pivoting in the longitudinal direction is provided on or in the rotation shaft. A separate seat for the axis of rotation is thus not necessary. The support is constructed very small in the width direction.
Another variant of the invention provides that the rotation shaft has a recess in which a pivotable arm is supported, which is directly connected to the holder. The pivotable arm is supported on an axis for movement/pivoting in the longitudinal direction. As already stated, the axis of rotation for movement/pivoting in the longitudinal direction and the axis of rotation of the rotary shaft should not intersect.
Preferably, the brush body is a brush body having a length of at least 100mm in the aperture area of the broom.
The width of the hole area is at least 10mm.
The central axis of the turntable can be a first axis of rotation for movement in the width direction.
In this case, a variant of the invention proposes that the second axis of rotation for movement in the width direction lies in the range from 125mm to 175mm from the first axis of rotation, i.e. moves about the axis of rotation over a diameter of 250mm to 350mm.
The brush body has an outward, i.e. radially outwardly directed hole area, the smallest distance of its outer side from the centre axis being in the range of 250mm to 275mm, such that the outer side moves around the centre axis on a circle having a diameter of 500mm to 550 mm.

Detailed Description
In fig. 1, a brush drilling and stuffing machine 10 in the form of a rotary disk machine is shown. The schematically and simplified illustrated turntable 12 can be rotated about a central axis (also referred to as axis of rotation 14 in the following), more precisely in an unlimited range. The schematically shown holders 16 are arranged on the outside of the turntable 12, here three holders 16, which hold an elongate brush body 18.
The brush body 18 is a brush body for a broom, which brush body has radially outwardly directed hole areas 20, into which holes are first drilled and into which holes the bristle bundles 21 are then plugged with anchors 23 (see fig. 3).
The brush drill and packer has three stations distributed over the circumference of the rotary disk 12, which stations are preferably spaced apart from one another by 120 ° in the circumferential direction, but this is not to be understood as limiting, nor is the number of stations limited, but in the variant shown it is designed to be able to construct the rotary disk 12 as compactly as possible.
In a front view along the central axis (viewing direction in the direction of arrow a), there is a supply and removal station at about 11 o' clock, in which the brush body 18 is inserted into the holder 16 and the finished brush is removed from the holder. This can be done manually or automatically. Of course, it is also possible to provide supply and removal stations that are separate from one another.
Adjacent to the drilling station in the direction of rotation of the turntable 12 is a drilling station with a drill bit 22, wherein of course a plurality of drill bits can also be operated simultaneously.
Downstream of the drilling station in the transport direction of the rotary disk 12, a filling station is provided, which has a storage magazine 24 for the fibers, a separating device 26 for the bristle bundles 21 and a head 28 which can be moved linearly or on a curved path and in which a filling tongue can be moved, by means of which the anchor 23 together with the bristle bundles 21 folded around the anchor 23 is inserted into the holes in the brush body 18 in a known manner.
The brush bodies 18 formed on the machine 10 are all elongated and preferably also have elongated hole areas 20. The aperture region preferably has a length (here in the direction of arrow a) of at least 100mm.
The machine 10 is characterized by a high compactness, which can be achieved by a synergistic effect with respect to the arrangement of the brush body 18 and the movement kinematics of the holder 16.
The structure of machine 10 is described in more detail below.
The turntable 12 is rotatably supported on a base 30, in which a rotary drive for the turntable 12 is also arranged, for example.
The base 30 can be moved in the direction Y by a linear drive 1 And (5) moving. This movement by the base 30 also moves the turntable 12 in that direction. This means: in the embodiment shown, which is not to be understood as limiting, the turntable 12 is not oriented in the direction Y relative to the base 1 Moves, but both move together.
The stuffing station as a whole along direction Z F Motion and/or motion of only head 28. Here, theImportantly, the feed motion, i.e. along Z F The degree of movement of the direction (depth compensation) must be adjustable, since the holder 16 is at a different distance from the central axis depending on the position.
The drill bit 22 can be driven in the direction Z by its own drive and corresponding linear guide 0 The drive can be fixed to the base in a linear manner, wherein the adjustment travel is also variable here, as well as between the bores, in order to be able to compensate for the different orientations of the holder 16 depending on the orientation of the holder 16 and its different distances from the central axis.
Movement of the turntable 12 about the central axis produces a movement component X 1 . By means of this component of movement, not only the holder 16 is moved between the stations, but also in the drilling and tamping stations, via this component of movement X 1 The orientation of the brush body 18 in the so-called width direction B relative to the respective working tool, i.e. relative to the drill bit 22 and the head 28, is also determined and produced.
The width direction B is along the circumferential direction of the turntable 12, i.e. the direction X 1 (rotational direction and counter-rotational direction of the turntable 12) and extends perpendicularly to the so-called longitudinal direction L of the brush body 18. In the case where the brush body 18 is not bent, the longitudinal direction L extends parallel to the central axis in a state where the brush body 18 is accommodated in the associated holder 16.
In order to drill the individual hole areas 20, the holders 16 have to be adjusted in the longitudinal direction L and in the width direction B, more precisely between strokes. It must furthermore be possible to pivot at will, so that the hole area 20 can be tilted with respect to the drill bit 22 and the head 28 with different slopes. This means: the individual bores extend not only parallel to one another, but also at an angle to one another.
Movement in the width direction B is achieved not only via rotation about a central axis (hereinafter also referred to as the axis of rotation 14), but also by pivoting about the second axis of rotation 34, so as to enable the holder 16 to be moved in the direction X relative to the turntable 12 2 And (5) twisting. The respective second axis of rotation 34 can be said to be by supporting the holder 16 on the turntable 12 or in the turntable 12Implemented, and having its own driver.
For the stuffing process, a movement in the width direction B is now produced according to fig. 1. Assume that: in the position of the holder 16 in the filling station according to fig. 1, the head 28 is oriented with respect to the hole in order to be able to fill the hole, which is located on the lowermost longitudinal edge of the brush body 18. To fill the holes in the same column on the uppermost longitudinal edge of the brush body 18, the turntable 12 is pivoted clockwise (with reference to the viewing direction a) and at the same time the holder 16 is pivoted counter-clockwise about the second axis of rotation 34. Thus, for example, parallel holes vertically lying one above the other can be plugged. However, if the holes are oriented obliquely, for example on the longitudinal edge of the upper part, so that the broom has bristle bundles which curve outwards towards the edge, as is usual, the holder 16 is not pivoted so strongly counter-clockwise about the second axis of rotation 34 after rotation of the turntable 12, so that the hole region 20 is no longer at right angles to the movement of the head 28, but is instead inclined to the movement of the head 28. The same applies to the movement in the drilling station.
Each holder thus has its own drive about the second axis of rotation 34.
The movement in the width direction B takes place only by movement about two axes of rotation, namely about the first axis of rotation 14, here the central axis, and about the second axis of rotation 34.
The orientation and the movement/pivoting in the longitudinal direction L during drilling and tamping are likewise effected by means of two own drives for each holder 16, wherein the purely longitudinal movement is effected by means of a linear drive which enables a linear support of the holders 16 and their movement in the direction of the rotational axes 14, 34. For this purpose, for example, a so-called rotation shaft 36 of each holder 16, which is responsible for rotation about the rotation axis 34, can be adjusted more or less away from the turntable 12 in the direction of the rotation axis.
A movement must also be achieved, by means of which the brush body 18 can be tilted or tilted in a second direction, i.e. in a longitudinal direction L extending perpendicularly to the direction about the axis of rotation 34. For this purpose, a rotary support 38 is provided at the rotationOn the shaft 36, the rotational support defines a rotational axis 40 for adjustment in the longitudinal direction L and the brush body 18 is inclined in this direction. This direction is by means of arrow Y in fig. 1 2 And (3) representing.
The structure of the rotating shaft 36 is shown in fig. 3. As already seen in fig. 1, the rotational shaft 36 has some type of recess or slot 44 in which the pivotable holder 16 is partially accommodated.
The holder 16 is supported with its axis of rotation, in this case more precisely with a rotation pin 46, in the rotation support 38. Thus, two opposite walls of the rotation shaft 36 are created via the recess or slot 44, in which the rotation support 38 is arranged, respectively.
Furthermore, the lever 48 extends in the direction of the second axis of rotation 34, wherein the lever 48 is in the embodiment shown a toothed rack which engages with a toothed section (arm) of the holder 16. By moving the lever 48 in the direction of arrow B, the holder 16 rotates about the axis of rotation 40 and thus in the direction of arrow Y 2 Is pivoted in the direction of (a).
The lever 48 extends partially through the rotational shaft 36 and is adjustable relative to the rotational shaft 36 in the direction of arrow B. However, the lever 48 together with the rotation shaft 36 is along the direction X about the second rotation axis 34 2 Pivot so that the retainer, and thus the brush body 18, can be adjusted in that direction.
The aforementioned movement of the rotary shaft 36 in the direction of the rotary axis 34 is indicated in fig. 3 by arrow C.
Fig. 4 shows an alternative driver. The rotation shaft 36, which is shown only very symbolically in the present case, can be placed in rotation, for example, via a belt drive 50, a chain drive or another drive. For this purpose, a corresponding servo drive is denoted by 52.
Another servo drive 54 is responsible for the linear adjustment of the lever 48 by: the actuating drive adjusts the threaded spindle 56 by means of its drive shaft, which is mounted in the rotary shaft 36 in a rotationally fixed, but axially displaceable manner.
The rotational movement of the servo driver 54 is thus converted into an axial movement.
Another feature can be seen in fig. 3. The axis of rotation 34 extends offset from the axis of rotation 40 such that the two axes of rotation 34, 40 do not intersect. However, the axis of rotation 40 lies in a radial plane of the axis of rotation 34, which should not be construed as limiting.
The compactness of the machine 10 in fig. 2 can also be defined via numerical values. Thus, the diameter D of the axis of rotation 34 about the central axis 1 250mm to 350mm.
The holder 16 is also arranged very close to the central axis. The hole region 20, which is completely radially outward in terms of orientation, has a diameter D of only 500mm to 550mm 2 Is shifted around the central axis.
Accordingly, a corresponding method for manufacturing an elongated brush with an elongated brush body comprises the steps of:
a turntable 12 is provided, which rotates about a central axis and is provided on its outer region with a plurality of holders 16 arranged one after the other in the direction of rotation,
a drilling station and a stuffing station following in the rotation direction are arranged,
the elongate brush body 18 is fixed to the holder 16 such that the width direction B of the brush body 18 is oriented in the direction of rotation, wherein thus for example the longitudinal direction of the elongate brush body extends parallel to the central axis,
rotating the turret 12, so that the holder 16 moves into the drilling station,
holes are drilled into the brush body 18, wherein movement of the brush body in the width direction B between drilling is performed by pivoting the holder 16 about two parallel, spaced-apart axes of rotation 14, 34, and
rotating the rotary disk 12 to move the drilled brush body 18 into the stuffing station, and
the bristle bundles 21 are stuffed into the drilled holes by means of anchors 23.
During drilling and tamping, the holder 16 is moved in the longitudinal direction at least by moving the holder 16 in the linear direction L and also by pivoting the holder 16 about the rotational axis 40 at the desired tilting.
The respective axis of rotation 40 can be tangential to the circumferential direction relative to the central axis.
With respect to the movement of the holder 16 about the axis of rotation 40, instead of a toothed rack, as shown in fig. 3, it is also possible to use a threaded spindle 56 which then extends to the holder 16 and engages there with a helical tooth or a nut or a ball nut.
It is emphasized that the above-described features are not necessarily functionally related to one another, but can also be used advantageously individually in differently configured drilling and packer machines.
