Definitions

  • the invention relates to a method and an apparatus for producing brushes which have a bristle carrier in which one or more bristles are fixed.
  • a bristle carrier in which one or more bristles are fixed.
  • Such a device is known for example from DE 196 34 278 A1 or
  • a stuffing station in which a stuffing tool is moved along a linear or slightly arcuate path with individual bristles or bristle tufts against the bristle carrier to force the bristle or bristle tufts into corresponding openings in the bristle carrier. Between each push, the bristle carriers are reoriented in two directions to align a free opening with the stuffing tool. There are several options for this orientation.
  • DE 196 34 278 A1 proposes to bring about the alignment 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 transversely to the direction of rotation, in which the holders are moved.
  • the object of the invention is to develop a method and a device that allow a simple, inexpensive construction of the device, the method should be reliable and easy.
  • the object is achieved by a method for producing brushes which have a bristle carrier in which one or more bristles are fixed and which is characterized by the following steps:
  • the holder on which the processing is taking place, is uncoupled from the chain link in any direction or to be aligned chain link from the rest of the chain. Rather, the entire located in the processing station chain link is aligned together with adjacent chain links, so less effort for the positioning of the bristle carrier in the processing station is required. In addition, chain and holder can be easily performed. Individual guides between chain link, holder and / or bristle carrier are no longer necessary.
  • the machining tool can perform a plurality of machining actions in which the bristle carrier to be processed is positioned differently from the machining tool, wherein the different positions are approached by the positioning means by moving the chain link in two directions.
  • An example of such a processing tool is a stuffing tool with individual Stopfh Wegney Co.
  • the chain is pivoted laterally in front of the processing station starting over several chain links.
  • the chain link which is located in the processing station, laterally moved, but an entire portion of the chain is pivoted laterally, so that the mobility of individual chain links to each other must be less than in the case 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 a chain length.
  • the folding is then increased and / or reduced. If the endless chain between two sprockets would be stretched so that a kind of oval results, all chain links of the chain, since it is stretched, would have to be moved for the rapid movement in the direction of rotation of the chain link in the processing station. This is on the one hand due to the inertial mass of the entire chain disadvantageous and otherwise the whole chain would thus permanently back and forth 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 stuffing station, in which a stuffing tool pushes at least one bristle, in particular a plurality of bristle tufts, into associated openings in the bristle carrier.
  • a stuffing tool pushes at least one bristle, in particular a plurality of bristle tufts, into associated openings in the bristle carrier.
  • the bristle carrier is positioned by the chain link is aligned.
  • the stuffing tool can only be moved back and forth along a fixed path of movement against the bristle carrier. This means that the stuffing tool itself is not aligned in multiple directions.
  • the alignment is rather over the bristle carrier. Laterally between the individual movement strokes, the bristle carrier is displaced by the positioning device in order to align another opening for darning with the stuffing tool.
  • the above object 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 circulating, endless chain with individual, pivotally attached chain links, on which holders for holding bristle carriers are provided, at least one processing station for performing at least one manufacturing step of the brush along the chain, wherein in the processing station, a processing tool for the bristle carrier is available.
  • the device comprises a positioning device in the processing station which is coupled to the chain link located in each case in the processing station.
  • the positioning device can align the chain link in at least two intersecting directions, wherein the positioning device and the machining tool are controlled such that the positioning device aligns the chain link and thus the bristle carrier to be processed relative to the machining tool for the subsequent processing step before machining.
  • the device according to the invention is in particular for carrying out the inventive Provided method and provides that the positioning device aligns the chain link in two directions and not only the holder on the chain link. After the adjacent chain links are coupled unchanged on the chain link to be aligned, the adjacent chain links are moved when aligning the located in the processing station chain link.
  • the chain according to the invention is preferably mounted so that it can pivot laterally in a direction transverse to the direction of rotation of the chain a plurality of chain links in front of the processing station.
  • the chain has a web guide, the web guide having a rigid portion over which the chain is positioned laterally away from the processing station.
  • the chain is laterally movable between the rigid section and the processing station, in particular pivotable.
  • the chain should therefore not be displaced and pivoted laterally over a large part of the chain length, but only in a relatively short section in front of the machining tool.
  • the chain is guided laterally exactly, so that here, for example, the holder can be fitted with the bristle carriers or the bristle carrier can be removed from the holders or other processing operations are performed, such as rounding or cutting the bristle ends.
  • the pivotable portion is moved laterally when aligning the chain link in the processing station laterally, u. U. also in the second direction.
  • the processing station may be a stuffing station with a stuffing tool, the stuffing tool preferably being moved against a sprocket.
  • the sprocket can thus absorb the forces directly through the stuffing tool, so that the bristle carrier is held stable and the entire holding system is little or not at all compliant.
  • the chain runs in the processing station via at least one sprocket.
  • the positioning device engages the sprocket and shifts this and thus the chain in two directions.
  • the chain itself is positioned very accurately, because the sprocket engages positively in the chain.
  • the sprocket is in particular a driven sprocket.
  • the pivotable portion of the web guide extends between the rigid portion and the positionable sprocket.
  • a simple embodiment of the positioning device is an XY carriage, which can be a favorable purchased part and, for example, comprises two electric motors which can be moved in two perpendicular directions, in particular servomotors.
  • the drive of the sprocket preferably sits on such an XY carriage so that sprocket and drive are moved together.
  • FIG. 1 shows a schematic side view of an embodiment of the device according to the invention for carrying out the method according to the invention
  • Figure 2 is a plan view of the device of Figure 1
  • FIG. 1 shows a device for producing brushes, which comprises a plurality of stations, namely a supply station 10 for bristle carrier 12 (see FIG. 2), a stuffing station 14 with a stuffing tool 16, in which the bristle carrier is stuffed with bristle tufts, a shearing station 18 in which the free ends of the bristle tufts are cut off, and a subsequent rounding station 20 in which the cut, free ends of the bristle tufts are rounded off.
  • the processing tools are thus stuffing tools, cutting and Abrundtechnikmaschinemaschinee.
  • a removal station 22 is provided, in which the finished brush 24 of the device are removed.
  • the holders 30 may be integral with the links 28 or may be attached to the outside of the links 28, for example, via 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, d. H. they are not displaceable during the process described below relative to their associated chain links 28 on which they are mounted.
  • the chain 26 comprises at least one driven sprocket 32 and an opposite sprocket 34, which may also be driven, but synchronized with the sprocket 32.
  • the sprocket 32 has two lateral gears 33 connected to a common drive shaft 35 are attached, which in turn from a drive motor 36, in particular in the form of an index motor is driven.
  • the chain 26 is held laterally between the gears 33.
  • Adjacent chain links 28, see Figure 1 are interconnected by a hinge 38 which projects laterally from the chain links.
  • the gears 33 have at their periphery recesses 41 (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 web guide 40 in the region of the joints 38, and indeed, as Figure 2 shows, by two lateral, z. B. U-shaped rails 42. Between these rails 42, the chain can be minimally moved transversely to the direction of rotation U at most, so that it is guided very well on the side.
  • the web guide 40 has for the relative to Figure 1 upper strand of the chain 26 and for the lower strand each have a rigid portion 44.
  • the chain in this rigid portion 44, the chain, as explained above, the side as good as not dodge in this direction to be perfect.
  • the rigid portion 44 does not extend all the way between the two sprockets 32, 34, but extends from the sprocket 34 to a location 50 that terminates a plurality of links 28 in front of the sprocket 32.
  • Between the point 50 and the sprocket 32 includes for the upper and for the lower run a pivotable portion 52 of the web guide 40 to the respective rigid portion 44 at.
  • the joints 38 are also received in two lateral U-shaped guides.
  • the movable portions 52 are preferably pivotable via a bearing or hinge 54 in the region of the transition to the respective rigid portion 44, as shown by the double arrow in Figure 2.
  • the respective pivotable portion 52 are also still pivotable about bearings 56 in the vertical direction to be minimally moved.
  • the stuffing station 14 which constitutes a processing station, there is a positioning device 60 (see FIG. 3) via which the sprocket 32 can be adjusted in two mutually perpendicular directions X and Y.
  • the direction X is the direction transverse to the circumferential direction U, and the direction Y is perpendicular thereto and preferably vertical.
  • the chain is moved from the point 50 together with the pivotable portion 52 of the web guide to openings 62 (see Figure 3) in the bristle carrier 12, which is to be stuffed with bristle tufts in to align this direction to the stuffing tool 16.
  • the stuffing tool 16 can make only a reciprocating feed movement in the direction Z (see Figure 2).
  • the axis Z is oriented so that it intersects the central axis A of the drive shaft 35 (see Figure 3).
  • the drive motor 36 together with the sprocket 32 is seated on an X-Y carriage 63 which has a base 64 on which a carriage 66 sits, which is along a guide 68 in the X direction by a motor 70, in particular a servomotor, movable ,
  • the pedestal 64 may be vertically aligned therewith via guides 72.
  • the Drive motor 74 then moves pedestal 64 vertically in the Y direction. Also, the motor 74 is preferably a servomotor.
  • the movement of the bristle carrier 12 in the Y direction can also be carried out by the motor 36 of the chain, in which case, however, it is necessary for the chain to be accommodated without play between the toothed wheels 33.
