Definitions

  • the invention relates to a method and a device for producing brushes which have a bristle carrier in which one or more bristles are fixed.
  • Such a device is, for example, from DE 196 34 278 A1 or the EP 0 563 419 B1 known. What these known methods and devices have in common is that the bristle carriers are moved along a revolving path on holders that are fastened to chain links of an endless chain. One or more processing stations are present along this path, through which the bristle carriers are transported and processed along the way. Such processing stations include, for example, stuffing, cutting off bristles or rounding off bristles. However, this list is not final.
  • the bristle carriers are clocked into the processing stations step by step and then guided out of the processing station again via the chain in the direction of the next processing station. In the processing station, the bristle carriers usually have to be aligned in two directions that intersect if this alignment does not take place by aligning the processing tool.
  • tamping station in which a tamping tool is moved along a linear or slightly curved path with individual bristles or bristle tufts against the bristle carrier in order to push the bristle or bristle tuft into corresponding openings in the bristle carrier.
  • the bristle heads are realigned in two directions in order to align a free opening with the tamping tool. There are several options for this alignment.
  • the DE 196 34 278 A1 proposes bringing about the orientation in the direction of rotation by moving the chain links and the orientation at right angles thereto by a relative movement of the holder on the associated chain links.
  • the holders have a longitudinal guide transverse to the direction of rotation, in which the holders are moved.
  • a brush manufacturing machine which has a spatially curved guide track in several directions. Corresponding curves run vertically but also horizontally in order to make the overall length of the brush manufacturing machine as small as possible and the transport device as compact as possible.
  • a chain consisting of several chain elements is guided in the guide track, on which holders for brush bodies are attached.
  • the individual chain links are connected to each other via a cardan joint in order to enable the relative movement of the chain links in many spatial directions.
  • the DE 10 2013 103 903 A1 also relates to a brush manufacturing machine having a track along which brush bodies are moved. Segments can be decoupled from the guide track relative to the rest of the guide track in order to move holders for brush bodies, which are moved along this guide track, in different directions during the tamping process.
  • the object of the invention is to develop a method and a device that allow a simple, inexpensive construction of the device, with the method being reliable and simple.
  • the holder on which the processing is currently taking place is not decoupled from the chain link in any direction, nor is the chain link to be aligned decoupled from the rest of the chain. Rather, the entire chain link located in the processing station, including adjacent chain links, is aligned so that less effort is required for positioning the bristle carrier in the processing station.
  • the chain and holder can be designed simply. Individual guides between the chain link, holder and/or bristle carrier are no longer necessary.
  • the processing tool can carry out several processing actions in which the bristle carrier to be processed is positioned differently from the processing tool, the different positions being approached by the positioning device by moving the chain link in two directions.
  • An example of such a processing tool is a tamping tool with individual tamping strokes between which the bristle carrier has to be repositioned.
  • the chain In order to align the bristle carrier in the processing station in a direction transverse to the direction of rotation of the chain, the chain is moved laterally over several chain links, beginning in front of the processing station pivoted. In order to realize the movement transverse to the direction of rotation, not only the chain link, which is located in the processing station, is moved laterally, but rather an entire section of the chain is pivoted laterally, so that the mobility of individual chain links relative to each other must be less than in the case that only the chain link located in the processing station is moved laterally to the rest of the chain.
  • the chain can be folded in sections before and/or after the processing station to produce an excess chain length. When aligning the chain link in the direction of rotation, the folding is then enlarged and/or reduced. If the endless chain were tensioned between two sprockets, resulting in a kind of oval, all chain links of the chain would have to be moved as well for the rapid movement in the direction of rotation of the chain link in the processing station, since the chain is tensioned. On the one hand, this is disadvantageous due to the inertial mass of the entire chain and, moreover, the entire chain would be moved back and forth permanently in the direction of rotation, so that a separate alignment of the chain in another processing station would no longer be possible.
  • the processing station is in particular a tamping station in which a tamping tool pushes at least one bristle, in particular several tufts of bristles, into associated openings in the bristle carrier.
  • the bristle carrier is then positioned between the individual stuffing strokes by aligning the chain link.
  • the tufting tool can only be moved back and forth against the bristle carrier along a fixed path of movement. This means the tamping tool itself is not oriented in multiple directions. Rather, the alignment takes place via the bristle carrier.
  • the bristle carrier is shifted laterally between the individual movement cycles by the positioning device in order to align another opening for stuffing with the stuffing tool.
  • the object mentioned above is also achieved by a device for producing brushes which have a bristle carrier in which one or more bristles are fixed.
  • the device according to the invention comprises a revolving, endless chain with individual chain links pivotably attached to one another, on which holders for holding bristle carriers are provided, at least one processing station for carrying out at least one manufacturing step of the brush along the chain, with a processing tool for the bristle carrier in the processing station is available.
  • the device comprises a positioning device in the processing station, which is coupled to the chain link located in the processing station.
  • the positioning device can align the chain link in at least two intersecting directions, with the positioning device and the processing tool being controlled in such a way that the positioning device aligns the chain link and thus the bristle base to be processed relative to the processing tool for the subsequent processing step before processing.
  • the device according to the invention is intended in particular for carrying out the method according to the invention and provides that the positioning device aligns the chain link in two directions and not just the holder on the chain link. After the adjacent chain links are coupled unchanged to the chain link to be aligned, the adjacent chain links are also moved when aligning the chain link located in the processing station.
  • the chain is preferably mounted in such a way that it can pivot several chain links laterally in front of the processing station in a direction transverse to the direction of rotation of the chain.
  • the chain has a track guide, the track guide having a rigid portion over which the chain is laterally positioned remote from the work station.
  • the chain is laterally movable, in particular pivotable, between the rigid section and the processing station.
  • the chain should therefore not be laterally shifted and pivoted over a large part of the chain length, but only in a relatively short section in front of the machining tool.
  • the chain is precisely guided laterally, so that the holders are fitted with the bristle carriers here, for example or the bristle bases can be removed from the holders or other processing operations can be carried out, such as rounding off or cutting the bristle ends.
  • Exact alignment of the movable part of the chain can be facilitated by the web guide having a pivoting section between the rigid section and the processing station, in which the chain is held transversely to the direction of rotation and is movable together with the pivoting section.
  • This pivotable section of the track guide relieves the joints between adjacent chain links.
  • the pivotable section is moved passively laterally, possibly also in the second direction.
  • the processing station can be a tamping station with a tamping tool, the tamping tool preferably being moved against a sprocket.
  • the sprocket can thus directly absorb the forces from the tufting tool, so that the bristle carrier is held stably and the entire holding system is little or not at all flexible.
  • the chain runs over at least one sprocket in the processing station.
  • the positioning device acts on the sprocket and moves it and thus the chain in two directions. This means that the chain itself is positioned very precisely, because the sprocket engages with the chain in a form-fitting manner.
  • the sprocket is in particular a driven sprocket.
  • a sprocket can act on opposite outer sides of the chain, with the two sprockets being rotationally coupled to one another. This means that the chain link located in the processing station is held directly on the sprocket at its two outer ends as viewed in the directions of circulation.
  • pivotable section of the web guide runs between the rigid section and the positionable chain wheel.
  • a simple configuration of the positioning device is an X-Y carriage, which can be a cheap purchased part and, for example, comprises two electric motors, in particular servomotors, that can be moved in two vertical directions.
  • the drive of the sprocket is preferably seated on such an X-Y carriage so that the sprocket and drive are moved together.
  • a device for manufacturing brushes which comprises a number of stations, namely a feed station 10 for bristle carriers 12 (see FIG figure 2 ), a tamping station 14 with a tamping tool 16 in which the bristle carrier is stuffed with tufts of bristles, a shearing station 18 in which the free ends of the tufts of bristles are cut off, and a subsequent rounding station 20 in which the free ends of the bristle tufts that have been cut are rounded off .
  • the processing tools are consequently stuffing tools, cutting tools and rounding tools.
  • a removal station 22 is also provided, in which the finished brushes 24 are removed from the device.
  • the bristle carriers 12 are transported through the stations and partly in the stations by a driven, revolving, endless chain 26, see FIG figure 2 , with chain links 28 arranged one behind the other and pivotably attached to one another, of which only two chain links are shown in figure 2 are provided with reference symbols.
  • Holders 30 are seated on the chain links 28 and have corresponding holding feet or recesses in order to accommodate and fix the bristle carriers 12 .
  • the holders 30 can be an integral part of the chain links 28 or, for example, can be fastened to the outside of the chain links 28 by a type of quick-release fastener.
  • the attachment of separate holders 30 to the chain links 28 has the advantage that the device can be converted very quickly if other shapes of bristle carriers 12 are to be processed in the device.
  • the holders 30 are fixedly mounted on the chain links 28, i. H. they are not slidable relative to their associated chain links 28 on which they are mounted during the process described below.
  • the sprocket wheel 32 has two side gears 33 which are fixed to a common drive shaft 35 which in turn is driven by a drive motor 36, in particular in the form of an index motor.
  • the chain 26 is held between the gears 33 laterally.
  • Adjacent chain links 28, see figure 1 are connected to each other by a joint 38 which protrudes laterally opposite the chain links.
  • the gear wheels 33 have recesses 41 on their circumference (see figure 1 ), which receive the joints 38 and thus transport the chain in the direction of rotation U intermittently.
  • the chain 26 is guided in a track guide 40 in the area of the joints 38, namely how figure 2 shows, by two lateral, z. B. U-shaped rails 42. Between these rails 42, the chain can at most be minimally moved transversely to the direction of rotation U, so that it is very well guided laterally.
  • the web guide 40 has based on the figure 1 upper strand of the chain 26 and for the lower strand in each case a rigid section 44.
  • the chain as previously explained, can hardly deviate laterally in order to be guided perfectly in this direction.
  • the rigid section 44 does not extend over the entire length between the two sprockets 32, 34, but extends from the sprocket 34 to a point 50 which ends several chain links 28 in front of the sprocket 32.
  • a pivotable section 52 of the web guide 40 connects to the respective rigid section 44 for the upper and for the lower run.
  • the movable sections 52 can preferably be pivoted via a bearing or joint 54 in the area of the transition to the respective rigid section 44, as indicated by the double arrow in FIG figure 2 shown.
  • the respective pivotable section 52 can also be moved minimally in the vertical direction in a pivotable manner about bearing 56 .
  • the tamping station 14 which represents a processing station, there is a positioning device 60 (see figure 3 ) available, via which the chain wheel 32 can be adjusted in two mutually perpendicular directions X and Y.
  • the X direction is the direction transverse to the circumferential direction U and the Y direction is perpendicular thereto and preferably vertical.
  • the chain is moved from the point 50 together with the pivotable section 52 of the web guide to open openings 62 (see Fig figure 3 ) in the bristle carrier 12, which is about to be stuffed with tufts of bristles, in this direction to the stuffing tool 16.
  • the tamping tool 16 can only perform a reciprocating infeed movement in the Z direction (see figure 2 ).
  • Axis Z is oriented to intersect central axis A of drive shaft 35 (see Fig figure 3 ).
  • the drive motor 36 together with the chain wheel 32 is seated on an XY carriage 63 which has a base 64 on which is seated a carriage 66 which is movable along a guide 68 in the X direction by a motor 70, in particular a servo motor.
  • the base 64 can be aligned vertically via guides 72 thereover.
  • a drive motor 74 then moves the base 64 vertically in the Y direction.
  • Motor 74 is also preferably a servo motor.
  • the movement of the bristle carrier 12 in the Y-direction can also be effected by the motor 36 of the chain, in which case, however, it is then necessary for the chain to be accommodated between the gear wheels 33 without play.
  • the guides 72 and the motor 74 are omitted.
  • the chain 26 can optionally be folded, for example, shortly before and after the chain wheel 32, i.e. both on the upper and on the lower strand, as in Figure 1a , shown above.
  • the fold bears the reference number 78.
  • This additional length of the chain 26 gained by the fold 78 allows it to be moved more easily in the Y-direction by the positioning device and is decoupled from the rest of the chain in this area.
  • the fold can be produced, for example, by an additional chain wheel 80 which begins after the pivotable section 52 of the web guide 40 .
  • the fold can be outwards, as in Figure 1a , run or inwards towards the other strand.
  • the bristle carriers 12 are slipped onto the corresponding holders 30 so that they sit on the holders 30 without play, with the openings 62, for example previously produced, pointing upwards.
  • the chain 26 is driven by the motor 36 in a fixed cycle.
  • a bristle carrier 12 As soon as a bristle carrier 12 has reached the tufting station 14, it is tufted with a plurality of tufts of bristles by the tufting tool 16, with figure 2 corresponding magazines 84 with differently colored bristles are shown, as is a so-called tuft separator 86.
  • the tufting tool 16 can be a conventional tufting tool, which is moved back and forth along the Z direction or along a trajectory and always picks up a tuft of bristles and places it in the corresponding opening 62, which is aligned straight towards the tamping tool 16. It can be stuffed with or without an anchor.
  • the positioning device 60 is used to align the bristle carrier 12 to be processed in the X and Y directions during the individual tufting strokes.
  • the corresponding bristle carrier is then indexed further until it comes to the shearing station 18 where the bristle ends are trimmed and then rounded off in the rounding station 20 .
  • the stations 18 and 20 can also be omitted if, for example, the bristles are not fixed in the corresponding opening 62 by an anchor, but their ends are first fused by heating in order to then be overmoulded.
  • holders 30 for several bristle carriers 12 can be used on individual chain links 28 .
  • a chain link 28 located in the tufting station 14 is positioned in the device in the X and Y directions, and the holder 30 is thus positioned on this chain link 28 together with the bristle carrier(s) 12 located thereon for processing positioned.
  • the point 50 is about one meter away from the chain wheel 32.
