AI Technical Summary
Existing brush drilling and packing machines struggle to achieve high cycle rates and compact design, particularly for elongated brushes like brooms, due to the need for precise, multi-directional movement of holders and significant moving masses, which limits efficiency and space utilization.
A method and machine design that utilizes a carousel with holders aligned parallel to the central axis, employing two separate drives for pivoting movements around parallel axes of rotation to minimize moving masses and increase compactness, allowing for efficient drilling and packing of elongated brushes by aligning brush bodies laterally and longitudinally.
The method and machine achieve higher cycle rates and a more compact design by minimizing moving masses and optimizing holder movement, enabling efficient drilling and packing of elongated brushes with angled bristle tufts, particularly for brooms, thereby enhancing production efficiency.
Description
[0001] The invention relates to a method for manufacturing elongated brushes having an elongated brush body and to a brush drilling and packing machine for carrying out the method.
[0002] In particular, the invention relates to a method and a machine in which elongated brush bodies are attached to holders which in turn are attached to a carousel rotating about a central axis.
[0003] Such carousel drilling and tucking machines for brushes have been known in principle for a long time. The advantage lies in the fact that several holders are mounted on the carousel, which accommodate the brush bodies and are rotated around the central axis. Various stations are provided around the circumference: a feed and / or removal station for brush bodies and finished brushes, a drilling station where holes are drilled into the brush body, and a subsequent tucking station where bristle tufts are inserted and secured in the previously drilled holes by means of an anchor (i.e., a bent wire loop or a flat wire plate).
[0004] While some brush bodies already have the holes for anchoring the bristle tufts pre-drilled during injection molding, these holes are essentially parallel to each other and aligned in the demolding direction. However, especially with household brushes and brooms, it's important that the bristle tufts aren't all parallel, but rather that it's possible to have angled bristle tufts, particularly at the edge of the brush body. For this reason, the holes are drilled separately for such brushes—that is, brushes that are not toothbrushes or nail brushes and are commonly referred to as household brushes and brooms.
[0005] Since the so-called hole pattern has numerous holes arranged side by side, the brush body is moved stepwise relative to the drill bit or tamping tool in the drilling station and subsequently in the tamping station to drill or tampe one hole after the other. The orientation of the brush body relative to the drill bit and tamping tool differs significantly from other holes in some cases to achieve the desired hole alignment. Therefore, the holders must be moved precisely in at least two spatial directions at high speed between the individual drilling and tamping cycles. To offer a highly efficient machine overall, the moving masses should be kept as low as possible.
[0006] The carousel, also known as a drum, rotates around its central axis, and in the prior art, the brush bodies are aligned with their longitudinal axis in the circumferential direction, i.e., in the direction of rotation of the carousel. This type of machine with such an orientation of the brush bodies has become established in the market. To increase the output rate, some models include two drilling stations and two tamping stations. With small brushes, 1,000 drilling and tamping operations per minute can be achieved; with larger brushes and brooms whose bodies have a length of at least approximately 400 mm, such cycle rates are not possible.
[0007] German patent applications DE 1 632 361 A1 and GB 275 692 A1 each disclose a brush drilling and packing machine comprising a drilling station and a packing station, which are traversed in the specified sequence. The brush bodies, which are fixed in holders, can be rotated about two different axes, the movement of which is mechanically linked.
[0008] The invention is disclosed in the claims.
[0009] The object of the invention is to provide a method for manufacturing elongated brushes, enabling brush drilling and packing machines to operate at higher cycle rates and be designed more compactly. A brush drilling and packing machine according to the invention is intended to achieve the same advantages.
[0010] The inventive method for manufacturing elongated brushes having an elongated brush body is characterized by the following steps: Providing a carousel that rotates about a central axis and on whose outer surface several holders are arranged one behind the other in the direction of rotation, providing a drilling station and a tamping station following in the direction of rotation, attaching elongated brush bodies to the holders such that one width direction of the brush body is aligned in the direction of rotation, rotating the carousel so that a holder is moved into the drilling station, drilling several holes into the brush body, wherein the movement of the brush body between drilling operations in the width direction is effected by pivoting the holder about two parallel, separate axes of rotation, wherein two separate drives are provided, with each axis of rotation being assigned one of the two drives, and rotating the carousel so that the drilled brush body is moved into the tamping station, and tamping bristle tufts into drilled holes by means of an anchor.The movement of the brush body between packing operations in the lateral direction is achieved by pivoting the holder about the two parallel, separate axes of rotation.
[0011] The inventive method results in an extremely compact carousel in which the holders can be located very close to the carousel's central axis, thus minimizing the moving masses. This is achieved, among other things, by aligning the elongated brush bodies essentially parallel (depending on the brush body's orientation relative to the so-called perforated grid). The relatively small width of the brush body and its perforated grid, compared to its length, allows the brush bodies, despite their considerable length, especially in the case of brooms, to be positioned close to the central axis. A further important factor enabling this arrangement of the brush bodies close to the central axis results from the holder's movement in the drilling and packing station, which aligns the brush body laterally.For this purpose, the individual holders are not driven by at least one linear movement and a linear drive, but exclusively by two separate pivoting movements, each with its own drive, around two spaced-apart, parallel, separate rotary axes. The rotary axes themselves require very little space in the lateral direction, and their drives can be positioned far from the holders. The lateral alignment of the brush bodies and the drive via the two rotary axes thus complement each other perfectly in a synergistic manner. The lateral direction is the circumferential direction, i.e., the direction and counter-rotation of the carousel.
[0012] A drilling operation and a plugging operation are each a singular stroke of the respective tool with which a hole is drilled or a hole is plugged.
[0013] Of course, several drilling and stuffing tools can be provided side by side in the drilling or stuffing station in order to work simultaneously on the same or different brush bodies.
[0014] In one embodiment of the invention, during drilling and plugging, the holder is moved longitudinally by linear movement of the holder and, when tilted longitudinally, about a further axis of rotation. This movement along a straight line allows for the creation of large longitudinal hole patterns. By pivoting the holder, the brush body is tilted longitudinally to also tilt the drill holes along this axis.
[0015] The axis for pivoting the holder for movement, more precisely for pivoting in the longitudinal direction, lies in particular tangential to the circumferential direction or in a radial plane (plane perpendicular to the central axis of the carousel).
[0016] The machine's compactness can be increased by using a rod for longitudinal swiveling, which extends within a rotating shaft for lateral swiveling. The rod transmits the movement from an electric drive directly to the holder, or via a linkage to the holder, allowing the drive to be positioned away from the holder and thus away from the brush bodies. The rod's placement within or through the rotating shaft ensures both high compactness and very low moving masses, which are also located close to the central axis.
[0017] A threaded rod (including ball screws) or rack can be used as a rod, for example.
[0018] For lateral movement, as mentioned, there are two axes of rotation, referred to below as the first axis and the second axis. The first axis of rotation is, for example, the central axis of the carousel, so the corresponding drive of the carousel has a dual function. Furthermore, the advantage of this design lies in the fact that the second axis of rotation and the first axis of rotation can be relatively far apart, which simplifies the placement of the motor for the second axis of rotation, allowing the second axis of rotation to be positioned much closer to the central axis compared to the prior art.
[0019] Further compactness is achieved if the second axis of rotation for lateral movement and the axis of rotation for longitudinal movement / tilting do not intersect, even if the aforementioned rod extends through the rotating shaft. For tilting movements around the two axes of rotation—namely, the second axis and the longitudinal axis—it would be advantageous if they intersected. However, this results in increased installation space in the radial direction relative to the central axis.
[0020] In this context, it is advantageous if the axis of rotation for movement / swivel in the longitudinal direction is radially further away from the central axis than the second axis of rotation, whereby the distance of the axis of rotation for movement / swivel in the longitudinal direction is defined as the smallest distance of this axis of rotation from the center line.
[0021] The longitudinal movement of the holder can be achieved by moving the carousel itself, i.e., without providing a linear guide on the carousel, which would increase the carousel's footprint and mass. Specifically, it is not the carousel itself that moves, but rather the base to which the carousel is attached.
[0022] The method according to the invention is particularly intended for the manufacture of brooms, with a perforated field which has a length of at least 100 mm.
[0023] Furthermore, the invention provides a brush drilling and stuffing machine for carrying out the inventive method, with a carousel rotating about a central axis, on the outer side of which several holders arranged one behind the other in the direction of rotation are provided, a drilling station and a tamping station following in the direction of rotation, elongated brush bodies attached in the holders, wherein the brush bodies have a longitudinal direction and a lateral direction and the brush bodies are seated in the holders such that the lateral direction is aligned in the direction of rotation, wherein the holders are each mounted for movement in the lateral direction during drilling and tamping about two parallel axes of rotation, to which separate rotary drives are assigned.
[0024] With regard to the idea according to the invention, reference is made to the previously described method in detail, in which context the advantages were also highlighted.
[0025] The holders for longitudinal movement / pivoting during drilling and plugging are mounted on a rotary axis and are linearly movable. Pivoting in the longitudinal direction moves the longitudinal ends of the brush bodies along a circular path with an axial forward and backward movement component.
[0026] This linear mobility can be designed so that all holders are moved together by a common drive.
[0027] One variation involves making the carousel linearly movable, particularly by moving its base to allow all supports to move linearly in the longitudinal direction. This reduces the complexity of the carousel's bearing system relative to the base, as this bearing system does not also need to incorporate linear bearings.
[0028] Another variant of the invention provides that a rotary axis for the lateral movement comprises a mechanical rotary shaft through which a driven rod extends, generating the pivoting movement of the holder about a rotary axis for the movement / pivoting in the longitudinal direction.
[0029] As previously explained in connection with the method according to the invention, this rod can be a threaded rod or a rack.
[0030] A further reduction in the complexity of the kinematics for longitudinal drive results from the fact that a rotary axis for lateral movement comprises a previously mentioned rotating shaft through which the driven rod extends or in which it is supported, with the rotary axis for longitudinal movement / swivel being supported on or within this rotating shaft. Thus, a separate base for this rotary axis is not required. The bearing arrangement is very compact in the lateral direction.
[0031] One embodiment of the invention provides that the rotary shaft has a recess in which a pivotable arm is mounted, which is directly connected to the holder. This pivotable arm is mounted on the axis of rotation for movement / pivoting in the longitudinal direction. As already explained, the axis of rotation for movement / pivoting in the longitudinal direction and the axis of rotation of the rotary shaft should not intersect.
[0032] Preferably, the brush bodies are those of a broom with a hole field length of at least 100 mm.
[0033] The width of the perforated panel is at least 10 mm.
[0034] The central axis of the carousel can be a first axis of rotation for movement in the lateral direction.
[0035] In this context, one variant of the invention provides that the second axis of rotation for movement in the lateral direction is located in a range of 125 to 175 mm away from the first axis of rotation, i.e., it moves around the axis of rotation over a diameter of 250 to 350 mm.
[0036] The brush bodies have an outwardly, i.e. radially outwardly pointing perforation field with an outer surface whose smallest distance to the central axis is in the range of 250 to 275 mm, so that the outer surface is moved on a circle with a diameter of 500 to 550 mm around the central axis.
[0037] Further features and advantages of the invention will become apparent from the following description and from the following drawings, to which reference is made. The drawings show: Figure 1 a perspective view of a variant of the brush drilling and stuffing machine according to the invention for carrying out the method according to the invention, Figure 2 the brush drilling and stuffing machine after Figure 1 , in which some dimensions are depicted, Figure 3 an enlarged sectional view in the area of the holder for a brush body of the brush drilling and packing machine according to the invention, and Figure 4 a schematic view of a drive unit for the holder of the brush drilling and stuffing machine according to the invention.
[0038] In Figure 1 Figure 10 shows a brush drilling and packing machine, which is designed as a carousel machine. A carousel 12, shown schematically and in a simplified manner, is rotatable about a central axis (hereinafter also referred to as the axis of rotation 14) to an unlimited extent. On the outside of the carousel 12, schematically depicted holders 16 are arranged, here three holders 16, which hold an elongated brush body 18.
[0039] The brush body 18 is here a brush body for a broom, which has a radially outwardly directed hole field 20, into which holes are first drilled and then bristle tufts 21 are stuffed into these holes using an anchor 23 (see Figure 3 ).
[0040] The brush drilling and packing machine has three stations distributed around the circumference of the carousel 12, preferably spaced 120° apart in the circumferential direction, although this is not to be understood as a limitation. The number of stations is also not limiting; however, in the illustrated variant, it is designed to make the carousel 12 as compact as possible.
[0041] In a front view (looking in the direction of arrow A) along the central axis, approximately at the eleven o'clock position, is the infeed and outfeed station, where brush body 18 is inserted into a holder 16 and the finished brush is removed from it. This can be done manually or automatically. Of course, separate infeed and outfeed stations can also be provided.
[0042] In the direction of rotation of the carousel 12, a drilling station with a drill 22 is attached, whereby of course several drills could also work simultaneously.
[0043] In the transport direction of the carousel 12 after the drilling station, a stuffing station is provided, with a magazine 24 for fibers, a singulation device 26 for bristle tufts 21 and a head 28 that can be moved linearly or on a curved path, in which a stuffing tongue is movable, with which an anchor 23 together with a bristle tuft 21 folded around the anchor 23 is driven into a hole in the brush body 18 in a known manner.
[0044] The brush bodies 18, which are machined on the machine 10, are all elongated and preferably also have an elongated perforated field 20. Preferably, the perforated fields have a length (here in the direction of arrow A) of at least 100 mm.
[0045] The machine 10 is characterized by a high degree of compactness, which is made possible by a synergistic effect regarding the arrangement of the brush bodies 18 and the movement kinematics of the holders 16.
[0046] The following section describes the more detailed construction of machine 10.
[0047] The carousel 12 is rotatably mounted on a base 30, in which, for example, the rotary drive for the carousel 12 is also housed.
[0048] The base 30 is movable in direction Y1 by a linear drive. This movement of the base 30 also moves the carousel 12 in this direction. This means that, in the illustrated embodiment, which is not to be understood as limiting, the carousel 12 is not moved relative to the base in direction Y1, but rather both move together.
[0049] The stuffing station is moved either as a whole towards the ZF and / or only the head 28. It is important that the feed movement, i.e. the extent of the movement towards the ZF (depth compensation), must be adjustable, because the holders 16 are at different distances from the central axis depending on their position.
[0050] The drill 22 is linearly adjustable in the direction Z 0 by means of its own drive, which can be attached to the base 30 and a corresponding linear guide, whereby the adjustment stroke is also variable here, even from borehole to borehole, in order to compensate for the different position of the holder 16 depending on the orientation of the holder 16 and its different distance to the central axis.
[0051] The movement of the carousel 12 around the central axis generates a motion component X 1. This motion component not only moves the holders 16 from station to station, but also determines and generates the orientation of the brush body 18 to the respective machining tool, i.e., to the drill 22 and the head 28, in a so-called width direction B in the drilling and tamping stations.
[0052] The width direction B runs in the circumferential direction, i.e. in the direction X 1 , of the carousel 12 (direction and counter-direction of rotation of the carousel 12) and perpendicular to the so-called longitudinal direction L of the brush bodies 18. When the brush body 18 is not cranked, the longitudinal directions L run parallel to the central axis in the state when these brush bodies 18 are received in the associated holders 16.
[0053] To drill the individual holes in the hole pattern 20, the holder 16 must be adjusted longitudinally L and laterally B, from stroke to stroke. Furthermore, it must be possible to pivot freely so that the hole pattern 20 can be tilted at various angles to the drill 22 and also to the head 28. This means that the individual drill holes are not only all parallel to each other, but can also be angled sharply to one another.
[0054] The movement in the lateral direction B is achieved not only by rotation about the central axis (hereinafter also referred to as axis of rotation 14), but also by pivoting about a second axis of rotation 34, about which the holders 16 can be rotated relative to the carousel 12 in the direction X 2. The corresponding second axis of rotation 34 is realized, so to speak, by a bearing of the holders 16 on or in the carousel 12 and has its own drives.
[0055] For the stuffing process, the movement in the lateral direction B is now determined by Figure 1 explained. It is assumed that when holder 16 is positioned in the packing station according to Figure 1The head 28 is aligned with a hole to fill it, which is located on the lower longitudinal edge of the brush body 18. To fill a hole in the same slot, which is located on the upper longitudinal edge of the brush body 18, the carousel 12 is pivoted clockwise (with respect to the viewing direction A) and simultaneously the holder 16 is pivoted counterclockwise about the second axis of rotation 34. This allows, for example, vertically superimposed, parallel holes to be filled. However, if the holes are, for example, oriented at an angle on the upper longitudinal edge, so that the brush has bristle tufts angled outwards towards the edge, as is usual, the holder 16 is pivoted less strongly counterclockwise about the second axis of rotation 34 after the carousel 12 has been rotated, so that the hole field 20 is no longer perpendicular to the movement of the head 28, but at an angle. The same applies to movement within the drilling station.
[0056] Each holder thus has its own drive around the second axis of rotation 34.
[0057] The movement in the lateral direction B is only achieved by the movement around the two axes of rotation, namely around the first axis of rotation 14, which is the central axis here, and around the second axis of rotation 34.
[0058] The alignment and movement / swivel in the longitudinal direction L during drilling and plugging is also achieved by two separate drives for each holder 16, whereby the pure longitudinal movement is carried out by a linear drive that enables linear bearing of the holders 16 and their movement in the direction of the axes of rotation 14, 34. For this purpose, for example, the so-called rotary shaft 36 of each holder 16, which is responsible for the rotation about the axis of rotation 34, can be adjusted more or less far from the carousel 12 in the direction of the axis of rotation 34.
[0059] Furthermore, a movement must also be implemented by which the brush bodies 18 can be pivoted or tilted in a second direction, namely in the longitudinal direction L, which runs perpendicular to the direction around the axis of rotation 34. For this purpose, rotary bearings 38 are provided on the rotary shaft 36, which define an axis of rotation 40 for adjustment in the longitudinal direction L and for tilting the brush bodies 18 in this direction. This direction is indicated by the arrow Y 2 in Figure 1 designated.
[0060] In Figure 3 The structure of the rotating shaft 36 is shown. As already mentioned in Figure 1 As can be seen, the rotary shaft 36 has a kind of recess or slot 44 in which the swiveling holder 16 is partially received.
[0061] The holder 16 is mounted in the rotary bearing 38 with its axis of rotation, more precisely with a pivot pin 46. The recess or slot 44 thus creates two opposing walls of the rotary shaft 36, in each of which the rotary bearings 38 are provided.
[0062] Furthermore, a rod 48 extends in the direction of the second axis of rotation 34, wherein, in the illustrated embodiment, this rod 48 is a rack that meshes with a toothed section (arm) of the holder 16. By moving the rod 48 in the direction of arrow B, the holder 16 is pivoted about the axis of rotation 40 and thus in the direction of arrow Y 2.
[0063] The rod 48 extends partially through the rotating shaft 36 and is adjustable relative to the rotating shaft 36 in the direction of arrow B. However, the rod 48, together with the rotating shaft 36, is pivoted about the second axis of rotation 34 in the direction X 2 in order to adjust the holder and thus the brush body 18 in this direction.
[0064] The previously mentioned movement of the rotating shaft 36 in the direction of the axis of rotation 34 is in Figure 3 symbolized by arrow C.
[0065] Figure 4 Figure 52 shows optional drives. The rotating shaft 36, which is only shown very symbolically in this case, can, for example, be set in rotation by a belt drive 50, a chain drive, or another type of transmission. A corresponding servo drive for this purpose is designated by 52.
[0066] Another servo drive 54 is responsible for the linear adjustment of the rod 48 by using its drive shaft to adjust a spindle 56 which is mounted in the rotary shaft 36 in a rotationally fixed but axially displaceable manner.
[0067] The rotary motion of the servo drive 54 is thus converted into an axial motion.
[0068] Another special feature is in Figure 3 As can be seen, the axis of rotation 34 is offset from the axis of rotation 40, so that these two axes of rotation 34 and 40 do not intersect. However, the axis of rotation 40 lies in a radial plane to the axis of rotation 34, which should not be interpreted as a limitation.
[0069] The compactness of the machine 10 in Figure 2 It can also be defined using numerical values. For example, the diameter D1, on which the axis of rotation 34 moves around the central axis, is between 250 and 350 mm.
[0070] The holders 16 are also arranged very close to the central axis. The perforated field 20, which is oriented exactly radially outwards, travels around the central axis on a circle with a diameter D 2 of only 500 to 550 mm.
[0071] The corresponding process for manufacturing elongated brushes with an elongated brush body therefore comprises the following steps: Providing a carousel 12 that rotates about a central axis and on the outer surface of which several holders 16 are arranged one behind the other in the direction of rotation, providing a drilling station and a tamping station following in the direction of rotation, attaching elongated brush bodies 18 to the holders 16 such that a lateral direction B of the brush body 18 is aligned in the direction of rotation, for example, so that the longitudinal direction of the elongated brush body runs parallel to the central axis, rotating the carousel 12 so that a holder 16 is moved into the drilling station, drilling several holes in the brush body 18, wherein the movement of the brush body between drilling operations in the lateral direction B is effected by pivoting the holder 16 about two parallel, separate axes of rotation 14, 34, and rotating the carousel 12 so that the drilled brush body 18 is moved into the tamping station, and tamping bristle tufts 21 into drilled holes by means of a Ankers 23.
[0072] In the longitudinal direction, the holder 16 is moved during drilling and plugging at least by moving the holder 16 in the linear direction L and, if an inclined position is desired, also by pivoting the holder 16 about the axis of rotation 40.
[0073] The corresponding axis of rotation 40 can be tangential to the circumferential direction with respect to the central axis.
[0074] Regarding the movement of the holder 16 about the axis of rotation 40, a rack can also be used instead of a rack, as in Figure 3 shown, the spindle 56 is used, which then extends to the holder 16 and meshes there with a helical toothing or a threaded nut or ball screw nut.
[0075] It should be emphasized that the aforementioned features are not necessarily functionally linked, but can also be used advantageously individually in differently designed drilling and stuffing machines.
