Definitions
- the invention relates to a device for producing brushware, in particular brushes or brooms, with a tamping tool for tamping bristle bundles in a ready bristle carrier and a bristle displacer for displacing already stuffed bristle bundles from a tamping area of the tamping tool.
- bristle displacers in the form of plates or metal sheets are acted upon directly by the tamping tool of the respective device during the tamping process and are thereby moved.
- a device of the type mentioned which has the means and features of the independent device directed to such a device claims.
- the tamping tool be connected and driven via a tool linkage and the bristle displacer via a displacer linkage with a common drive shaft of the device.
- the coupling between the common drive shaft and the tufting tool and the bristle displacer can be designed in such a way that the return of the bristle displacer is positively coupled to the return of the tufting tool from a tufting position.
- the tool coupling mechanism comprises a tool eccentric and the displacer coupling mechanism comprises a displacer eccentric.
- the tool eccentric and the displacer eccentric can be arranged on the common drive shaft. With the help of the two eccentrics, the rotational movement of the common drive shaft can be converted into a corresponding movement of the tufting tool and the bristle displacer.
- the bristle displacer can be pivoted about an axis of rotation in order to carry out a displacement movement. In this case, the axis of rotation can be aligned parallel or at right angles or transversely to the direction of movement of the tufting tool when tufting bristles.
- the bristle displacer can be moved in a displacement movement in the form of an arc or a circular arc. If the axis of rotation of the bristle displacer parallel to the
- the displacement movement of the bristle displacer can be fan-shaped.
- the device can have a switching device for changing a displacement direction and/or a displacement path of the bristle displacement device.
- the switching device comprises a guide carriage and a linear guide, along which the guide carriage is movably mounted. In this case, an angular position of the linear guide can be changeable in order to set the displacement direction and/or the displacement path of the bristle displacement device.
- the guide carriage and the linear guide can be components of the displacer coupling mechanism already mentioned above, via which the bristle displacer is connected to the common drive shaft of the device.
- a displacement direction of the bristle displacement device and/or a displacement path of the bristle displacement device can be dependent on the angular position of the linear guide.
- the guide carriage can be connected to the bristle displacer via at least one lever, in particular via at least one articulated lever. In this way, the movement of the guide carriage can be transferred to the bristle displacer. Depending on the alignment and angular position of the linear guide, along which the guide carriage can be displaced, the displacement path and/or the displacement direction of the bristle displacer can be transferred to the bristle displacer via the lever.
- the guide carriage can be connected to the common drive shaft via a transmission means of the displacement linkage, for example via a transmission lever and/or the displacement eccentric.
- a transmission means of the displacement linkage and a transmission means of the tool linkage can be arranged, in particular mounted, on a common axis.
- the common axis can be aligned transversely or parallel to the common drive shaft.
- Levers can be used as transmission means, which can interact with the respective eccentric in order to convert the rotational movement of the common drive shaft into a movement of the tufting tool and the bristle displacer.
- the tool linkage can have a link guide.
- the link guide can be arranged, for example, on the tamping tool.
- the previously mentioned transmission means can be connected indirectly to the tamping tool via the link guide.
- the tool eccentric and the displacement eccentric can be designed and arranged on the common drive shaft in such a way that the bristle displacement element is arranged in the displacement position while the tufting tool is in the tufting position. In this way, collisions between the tufting tool and the bristle displacer can be avoided. It is also possible for the tool eccentric and the displacement eccentric to be designed and arranged on the common drive shaft in such a way that the bristle displacement element has already assumed its displacement position before the tamping tool has reached its tamping position. In this way, collisions between the tufting tool and the bristle displacer can be avoided in a particularly reliable manner.
- the bristle displacer has a displacer ring, into which the tamping tool dips in the tamping position. A collision between the bristle displacer and the tamping tool can be effectively avoided in this way.
- a sufficiently large area of already stuffed bristle bundles can be kept free in a simple manner that is gentle on the bristle bundles. In this way, further bristle bundles can be stuffed without damaging neighboring bristle bundles or accidentally stuffing neighboring bristle bundles.
- an outer peripheral surface of a tool tip of the tamping tool is designed to correspond to an inner peripheral surface of the displacement ring. In this way, the tamping tool can rest against the inner peripheral surface of the displacement ring with its tool tip.
- the bristle displacer can have at least one deflection means.
- a displacement tip for example, can be provided as at least one deflection means.
- the at least one deflection means of the bristle displacer can be used to deflect laterally to a direction of movement of the bristle displacer bristle bundles that have already been stuffed into a bristle carrier. Such a lateral displacement can be particularly gentle on the already clogged bundles of bristles.
- a displacement tip can have laterally sloping displacement surfaces with which bundles of bristles that have already been stuffed can be displaced laterally reliably and gently.
- a longitudinal axis of the at least one deflection means can be transverse or perpendicular to the direction of movement of the bristle displacer be aligned.
- the at least one deflection means can be arranged on an outside of the displacement ring.
- a deflection means in the form of a displacement tip is arranged on two opposite outer sides of the displacement ring.
- the device may include a motor for driving the common drive shaft.
- an output shaft of the motor can be connected to the drive shaft via a drive belt.
- the device has a holder for receiving at least one bristle holder, which can be adjusted in at least two different axes relative to the tamping tool is.
- the device can have a magazine in which bristle filaments are stored.
- the bristle filaments can be removed from the magazine together into bristle bundles using a bundle divider of the device and fed to the stuffing tool.
- the device can have an anchor feed device, with which anchors for fastening bristle bundles in a bristle carrier can be fed to the stuffing tool of the device.
- Figure 18 is a perspective view of a
- Bristle displacer to illustrate a first movement pattern in which the bristle displacer is pivoted about an axis of rotation which is aligned parallel to the direction of movement of the tamping tool during the tamping process
- Figure 19 is a second schematic representation of a
- Bristle displacement to illustrate a second movement pattern in which a Axis of rotation about which the bristle displacer can be pivoted is aligned transversely or at right angles to the direction of movement of the tamping tool when tufting bundles of bristles, and
- FIGS. 21 and 23 show displaced bristle bundles in order to illustrate the mode of operation of the bristle displacer, which can be advanced from different directions.
- All of the figures show a device, denoted overall by 1, for producing brushware 2.
- the brushware 2 that can be produced on the device 1 shown in the figures are brushes, in particular toothbrushes.
- the device 1 has a tufting tool 3 for tufting bundles of bristles 4 into a ready-held bristle carrier 5 of brushware to be produced and a bristle displacer 6 for displacing tufts of bristles 4 that have already been stuffed out of a tufting area of the tufting tool 3 .
- the device 1 is characterized in that the tamping tool 3 is connected via a tool linkage 7 and the bristle displacer 6 is connected via a displacer linkage 8 to a common drive shaft 9 of the device 1 and is driven by this jointly positively coupled.
- the bristle displacer 6 has assumed a specific position in its movement cycle.
- the tool coupling mechanism 7 includes a tool eccentric 10.
- the displacer coupling mechanism 8 includes a displacer eccentric 11. Using the tool eccentric 10 and the displacer eccentric 11, a rotational movement of the drive shaft 9 can be transmitted indirectly to the tufting tool 3 and the bristle displacer 6. For this purpose, the tool eccentric 10 and the displacement eccentric 11 are arranged on the common drive shaft 9 .
- the bristle displacer 6 can be pivoted about an axis of rotation 12 in order to carry out a displacement movement. According to FIGS. 18 and 19, depending on the embodiment of the device 1, the bristle displacer 6 can be pivotable about an axis of rotation 12 which is aligned parallel to the direction of movement of the tufting tool 3 (compare FIG. 18) or is oriented transversely or at right angles to the direction of movement of the tufting tool 3 ( compare figure 19).
- the bristle displacer 6 follows a fan-shaped path
- the device 1 shown in FIGS. 1 to 17 comprises a switching device 13 for changing a displacement direction and/or a displacement path of the bristle displacement device.
- the switching device 13 makes it possible to move the bristle displacer 6 into the tamping area of the tamping tool 3 from different directions.
- the bristle displacer 6 is fed from bottom to top, which is made possible by a corresponding position of the switching device 13 . In this way, a lower partial field of a bristle field of the bristle carrier 5 can be stuffed with bristle bundles 4 .
- the bristle displacer 6 is advanced to displace already stuffed bristle bundles from top to bottom, which is also effected by a corresponding switching position of the switching device 13 . This promotes the stuffing of an upper partial field of the bristle carrier 5 with bristle bundles 4.
- the switching device 13 of the device 1 shown in the figures comprises a guide carriage 14 and a linear guide 15.
- the guide carriage 14 can be displaced along the linear guide 15, a movement of the guide carriage 14 being converted into a displacement movement of the bristle displacer 6.
- An angular position of the linear guide 15 along which the guide carriage 14 is displaced can be changed here.
- FIGS. 1 to 8 A comparison of FIGS. 9 to 14 and 17 makes this clear.
- the switching device 13 has an actuator 16 with which the linear guide 15 can be pivoted.
- the displacement direction of the bristle displacement device 6 is also dependent on the angular position of the linear guide 15 as is a displacement path covered by the bristle displacement device 6 .
- the guide carriage 14 is connected to the bristle displacer 6 via at least one lever, namely via at least one articulated lever 17 .
- a movement of the guide carriage 14 can be converted into a movement of the bristle displacer 6 via the articulated lever 17 .
- the guide carriage 14 is in turn connected to the common drive shaft 9 via a transmission means 18 of the displacement linkage 8, namely via a transmission lever, and the displacement eccentric 11 already mentioned above.
- the transmission means 18 of the displacement linkage 8 and a transmission means 19 of the implement linkage 7 are arranged on a common axis 20 and are rotatably mounted. Levers are used as transmission means 18 and 19 .
- the tool linkage 7 also includes a slotted guide 21 which is arranged on the tamping tool 3 and serves to transmit a drive movement to the tamping tool 3 .
- the tool eccentric 10 and the displacement eccentric 11 are designed and arranged on the common drive shaft 9 in such a way that the bristle displacement element 6 is arranged in the displacement position before and even while the tamping tool 6 is in the tamping position. This is illustrated in particular by the representation of the device 1 according to FIG.
- the bristle displacement device 6 has a displacement ring 22 .
- the tamping tool 3 can dip into this displacement ring 22 in the tamping position. This is illustrated, for example, in Figures 6, 12 and 17.
- the bristle displacer 6 also has two deflection means 26 which are designed as displacer tips with displacer surfaces that are inclined at the sides. Using the deflection means
- the two deflection means 26 are arranged on an outside of the displacement ring 22 of the bristle displacement device 6 .
- the device 1 comprises a motor 27 for driving the common drive shaft, the output shaft of which is connected to the drive shaft 9 via a drive belt 28 .
- the device 1 also includes a holder 29 for receiving a bristle carrier 5.
- the holder 29 can be adjusted in at least two different axes relative to the tufting tool 3 in order to be able to position the bristle carrier 5 relative to the tufting tool 3 for stuffing its receiving holes with bristle bundles 4 .
- the device 1 also has a magazine 30 in which bristle filaments are stored. The bristle filaments can be removed from the magazine 30 together into bristle bundles 4 with the aid of a bundle divider 31 of the device 1 and fed to the tufting tool 3 .
- the device 1 also has an anchor feed device 32 with which the anchor for fastening the bristle bundles 4 in the bristle carrier 5 can be fed to the tufting tool 3 .
- a device 1 for this purpose, which has a tamping tool 3 for tamping bristle bundles 4 in a bristle carrier 5 provided and a bristle displacer 6 for displacing already tamped bristle bundles from a tamping area of the tamping tool 3 .
