Description

Brushing processing equipment

Technical Field

The invention relates to a bristle processing device for grinding the ends of bristles, having a bristle box in which the bristles are arranged upright next to one another.

Background

A general bristle processing device is known from EP 1 535 534 A2. The disk moves along the outlet opening of the bristle magazine with the circumference of the disk and has grooves on the circumference, so that the bristles standing in the bristle magazine are pushed into the grooves, in such a way that the bristle tufts are moved out of the bristle magazine. The disk rotates and then transfers the bristle tufts to another disk, which in turn has cavities on its outer circumference. The second circle is a transition magazine with different openings on its outer circumference, for example bristle tufts of different colors to be loaded. The oscillating so-called tuft picker removes smaller tufts, which are just as large as necessary subsequently during the filling process, from the transition magazine. The second disk is transported, depending on the bristle tufts to be processed, to a bristle tuft picker in such a way that it removes individual bristle tufts, for example blue or white bristles, from the respective supply. A grinding wheel is provided above the first disk. The bristle tufts are transported in sequence under the grinding wheel and then moved axially to the grinding wheel so that the ends of the bristle tufts are pressed against the grinding wheel and can be rounded by rotating the grinding wheel. After grinding, the grinding wheel and the bristle tufts are moved axially away from one another, while the bristle tufts which have just been ground are conveyed further.

In the past, there have been many ideas to optimize mechanical grinding devices not to round the bristles, but to make them pointed. However, these grinding devices do not produce fine, virtually pointed bristles, and thus the conventional method to date, so-called chemical grinding, remains the best method for producing bristles that taper to a certain cone angle. However, this method has a great influence on the environment.

Disclosure of Invention

The object of the invention is to further develop a bristle processing device of the type mentioned at the outset in such a way that bristles with a small cone angle can be mechanically sharpened, producing bristles of high quality.

This object is achieved by a bristle processing device for grinding bristle tips, having: a bristle box in which bristles, which are erected adjacent to each other, are distributed; a plurality of transition cartridges in which grooves are formed into which bristle tufts are pushed from a bristle cartridge and are isolated, wherein tips of the bristle tufts axially protrude with respect to the respective transition cartridge; a receiving unit to which a plurality of transition cartridges are attached at the same time and are movable; a grinding device and at least one drive for the transition magazine and/or the receiving unit, wherein the bristle tufts located in the transition magazine can be moved relative to the grinding device by means of the drive and the bristle tips are ground at least on one side of the transition magazine during the movement.

The bristle processing device according to the invention provides that several transition cartridges can be arranged in one receiving unit, so that a large number of bristle tufts are accommodated and therefore positioned for the subsequent grinding process. The relative movement between the bristles and the grinding means, achieved by moving the bristles and/or the grinding means, ensures that the bristles in the plurality of transition magazines are processed simultaneously.

The movement of the bristle tufts during the grinding process relative to the grinding device ensures that the individual bristles are treated from all sides, resulting in a tip that is as far as possible in the central axis of the bristles and a tapering of the bristle ends.

The relative movement between the bristle tufts and the grinding means is preferably designed so that the individual bristles are ground evenly from all sides so that the bristle tips are on the central axis of the cylindrical bristles. Thus, the bristle tips are tapered.

The transition magazine is preferably a component which can be automatically detached from the receiving unit, which component can be coupled to the receiving unit by the delivery device and can also be detached from the receiving unit again. For example, with a quick-disconnect mechanical coupling.

Preferably, the transition cartridge is filled with bristle tufts on the outside of the receiving unit. For this purpose, for example, a filling station for the transition magazine is provided outside the receiving unit, in which filling station the bristle tufts are inserted into the recesses in the transition magazine. There are also delivery means for transferring the filled transition magazine to the receiving unit.

For example, the transition magazine may be a tray or have trays stacked one above the other.

The recess may be present on the outer periphery of the transition cartridge, so that the bristle tufts can be pressed laterally into the transition cartridge from the outside.

An alternative of the invention provides that a frame-like delimiting means is surrounded on the periphery of each transition cartridge, a part of which delimiting means is laterally open. The delimiting means fix the bristle tufts transversely in the respective recesses. The lateral open section serves to push the bristle tufts laterally from the bristle magazine into the groove via the open section. The transition magazine is rotatable relative to the delimiting means, so that the recesses are successively fed into the open section for lateral exposure and for enabling insertion of the bristle tufts.

In order to ensure that the bristle tufts remain in the intermediate portion even during the transfer from the filling station to the receiving unit, it is optional to place the delimiting means together with the relevant intermediate portion from the filling station into the receiving unit.

The at least one driver may be a driver for the transition cartridge and/or the receiving means. In this case, a common drive for the transition magazine and also for the receiving device can be provided, or one or more drives for the transition magazine and one or more separate drives for the receiving device can be provided.

The receiving unit itself can also be a rotatably mounted disc attached to the base, wherein the disc is rotatably driven. However, this is only one option.

In principle, there are a number of possibilities for moving the bristle tufts relative to the grinding device. One of the methods is to rotate the transition cartridge relative to the stationary receiving unit.

Another way is that only the receiving unit with the transition cartridge fixed therein rotates, and a third way is that the transition cartridge rotates relative to the receiving unit and, in addition, the receiving unit also rotates relative to the stationary environment, so that there are two superimposed rotational movements here.

Alternatively, the opposite ends of the bristle tufts may be ground simultaneously, such as by providing two grinding devices, wherein each grinding device is assigned to one end of a bristle tuft. That is, both ends of the bristle tufts of one transition magazine are processed simultaneously.

However, another variant provides that only the bristle tuft tips which project on the same side of the transition magazine are ground simultaneously. In order to subsequently grind the other ends, a deflecting device for the transition magazine is provided, which deflects the transition magazine relative to the grinding device after one end of the bristle tuft has been ground.

The diverting means may be, for example, a reversible tray that can receive, remove and invert the transition magazine into the second receiving unit. The steering device has, for example, a horizontal pivot axis, which should not be understood as limiting.

The diverting means may comprise some kind of X-Y carriage or X-Y-Z carriage which is freely programmable in at least one plane or in all spatial directions for removing transition cartridges in turn from the receiving unit. The carrier is then rotated 180 ° and the transition magazine is placed in the other position, i.e. the other receiving unit. There may of course also be a plurality of simultaneously operating carriers with one common pivot axis.

As mentioned before, it is advantageous, but not absolutely necessary, to provide the grinding device to grind all bristle tufts in the receiving unit simultaneously.

However, it is also possible to design the grinding device such that, in the case of a plurality of receiving units, all bristle tufts in the plurality of receiving units are ground simultaneously.

In particular, the grinding device is a grinding belt, i.e. an annularly closed circumferential grinding belt.

As already mentioned, a drive can be provided for rotating the transition cartridge relative to the receiving unit during grinding and/or at least one drive can be provided for rotating the receiving unit with the transition cartridge attached thereto during grinding.

The grinding device is optionally designed to be moved in a plurality of directions, such as in the case of a circumferential grinding belt, which can be rotated with another drive, such as about an axis which is perpendicular to the grinding plane or more generally the grinding surface.

Detailed Description

Fig. 1 shows a bristle processing device 10 with which the tips of bristles that have been separated into bristle tufts are mechanically sharpened.

The bristle processing device 10 comprises one or more bristle magazines 12 in which the bristles are erected adjacent to one another and are preloaded, i.e. with lateral pressure. Furthermore, the bristle processing device 10 also comprises one or more receiving units 14, which in the present example are of disc-shaped design, which should not be understood as limiting.

Here, a plurality of transition cartridges 16, which are illustrated in detail in fig. 3 and 4, are arranged on the outer circumference of the receiving unit 14 in complementary-shaped recesses. Separated bristle tufts are accommodated in a transition magazine 16, which is described in more detail below.

Before the right-hand receiving unit 14, a filling station 17 is functionally provided, in which the separated bristle tufts 42 are inserted into the respective transition magazines 16.

The receiving unit 14 is secured to a base 18, such as a pallet.

Furthermore, a so-called deflecting device 20 is provided, to which one or more invertible holders 22 are attached, with which the transition magazine 16 can be removed from one receiving unit 14 and inverted through 180 °, i.e. with the other surface facing upwards, and placed into the other receiving unit 14.

One or more grinding devices 24, here two grinding devices adjacent to each other are provided, vertically movable above the base 18, as illustrated in fig. 2.

The grinding device 24 comprises a driven endless belt 26.

The bristle processing device 10 will be described in still further detail below.

Fig. 3 shows one of a plurality of transition magazines 16 each having a plurality of disks stacked one above the other. In fig. 3, the transition magazine 16 also has an upper cover 28, which is removed in fig. 4.

Below the upper cover 28, at least one receiving disk 30 is arranged, which has a plurality of radial recesses 32 on the outer circumference. Each recess 32 is provided with a pressure assembly 34 radially inside the recess 32, which is arranged radially movably in a corresponding slot in the receiving disc 30 and is prestressed radially outwards by means of its own spring device 36.

The receiving pan 30 and the transition magazine 16 are surrounded on the outer periphery by a U-shaped delimiting means 38, which may have an annular slot on the inner side relative to the outer periphery of the receiving pan 30, which is smaller than the diameter of one bristle. This means that the delimiting means 38 ensure that the bristles are retained in the recess 32 with respect to their movement. Instead of a slot, the delimiting means 38 may optionally have an upper plate and a lower plate which are situated axially above and below the receiving sleeve 30, respectively, and which end radially inside the outer periphery of the receiving sleeve 30, so to speak surrounding the edge of the receiving sleeve 30, so that, viewed axially, no slot is created between the outer periphery of the receiving sleeve 30 and the delimiting means 38.

Receiving the pan 30, more precisely the entire transition magazine 16, is rotatable about the central axis X with respect to the delimiting means 38.

The delimiting means 38, as mentioned, is U-shaped and has a receiving opening 40, through which the bristle tufts can be inserted into the transition magazine 16. By way of example, two bristle tufts 42 are illustrated in fig. 3 and 4.

The grooves 32 are arranged relatively close to each other, but on the periphery of the transition cartridge 16 there is a so-called enclosure 44 in which there are no grooves 32. If the closure portions 44 are aligned with the receiving apertures 40 as shown in fig. 3 and 4, all recesses 32 are closed via the delimiting means 38 and the pressure assemblies 34 are pressed radially outwards so that the associated bristle tufts 42 are pressed towards the inside of the delimiting means 38, as a result of which the bristle tufts 42 are held firmly in the unit of the transition magazine 16 and the delimiting means 38. As a result, no bristles will fall out.

In order to fill the individual recesses 32, the bristle cartridges and the transition magazine 16 to be filled are brought closer together in the filling station 17 together with the delimiting means 38.

This process can be implemented in different ways and methods. For example, the bristle cartridge 12 in fig. 1 can be moved along the longitudinal axis a of the bristle cartridge as well as to the unfilled transition magazine 16. However, it is also possible to move the transition magazine 16 together with the delimiting means 38 to the bristle magazine 12 in the opposite way.

In each case, as shown in fig. 1, the transition cartridge 16 to be filled is filled outside the receiving unit 14. The so-called output opening at the front end of the bristle cartridge 12 moves into the receiving aperture 40 until it reaches the outer periphery of the receiving plate 30.

The transition cartridge 16 is then rotated about the rotational axis X of the transition cartridge 16 using a rotary drive 46, shown symbolically in fig. 4, so that the recesses 32 are filled one after the other with bristles. For filling, the pressure assembly 34 can be pressed radially inward via a projecting projection 48, here for example via a pin on the upper side, or generally via a mechanical coupling. This can be done, for example, via a wedge-shaped fixing guide, which is a rigid part that bridges the receiving opening 40 and is designed such that, during rotation of the receiving sleeve 30, the projection 48 is moved along the guide so as to be moved radially inward in order to be able to migrate again to the outside when it is removed again from the receiving opening 40. In this manner, filling is accomplished without the resistance of the pressure assembly 34.

If all recesses 32 have been filled, the respective transition magazine 16 together with the delimiting means 38 is transferred to the receiving unit 14 by means of the conveying means 50 (see fig. 1). The receiving unit 14 has a coupling geometry for the delimiting means 38, for example a groove complementary thereto, so that the unit consisting of the delimiting means 38 and the transition magazine 16 is securely placed into the receiving unit 14.

The transport device 50 may be, for example, a carriage which is placed on a linear drive, or may be an X-Y slide or an X-Y-Z slide with a carriage.

Of course, any other delivery device 50 is also contemplated.

Each receiving unit 14 may be rotatably mounted on the base 18, such as by a respective driver 52, for example, but not by way of limitation. When the transition magazine 16 is filled and transferred to the receiving unit 14, the transfer to the receiving unit 14 can be continued all the way via the rotatable drive 52.

Alternatively, the receiving unit 14 is non-rotatably attached to the base 18, so that the delivery device 50 can accurately place the filled transition magazine 16 into the corresponding aperture in the receiving unit 14 after a corresponding rotation in each orientation.

As can be seen in fig. 3 and 4, the bristle tufts 42 project axially relative to the transition magazine 16 and also project significantly with respect to the delimiting means 38 in both axial tuft ends.

When the grinding device 24 is lowered according to fig. 2, it can contact the upper ends of the bristle tufts and grind the upper ends.

During the grinding process, the bristle tufts move relative to the bed 18.

This movement can be achieved in a number of ways.

A first variant consists in that the drive 52 rotates the receiving unit 14 during the grinding process. Because the transition cartridge 16 is coupled to the receiving unit 14, the transition cartridge 16 also rotates.

Another variant is that the driver 52, or one or more drivers not comprising the driver 52, each moves the transition magazine 16 in the receiving unit 14 about its own axis of rotation X during the grinding process.

For this purpose, for example, a driver is provided below the base 18, to which the transition cartridge 16 is coupled when it is used.

As an alternative, a central drive, for example drive 52, may of course be present, which drives the individual transition cartridges 16 via a transmission similar to a planetary gear, that is to say as a central drive.

A third variant provides that during the grinding process not only the receiving unit 14 is rotated, but also each transition magazine 16 is rotated about its respective axis of rotation X. This ensures a superimposed rotational movement, as is the case with a planetary gear with a spinning sun gear and a simultaneously rotating planet carrier.

The grinding device 24 is large enough so that all bristles set in the receiving unit 14 are ground simultaneously.

The relative movement between the grinding means 24 and the individual bristles is selected such that the bristles are evenly ground from all sides. The tip formed by each bristle is then relatively precisely located on the central axis of the cylindrical bristle, resulting in a tapered end.

After the tips of all the bristle tufts 42 have been sharpened on one side of the receiving unit 14, the transition magazine 16 together with the delimiting means 38 is removed from the right-hand receiving unit 14 in fig. 1 via the deflecting means 20.

The carrier 22 grasps one of the transition cartridges 16 with the delimiting means 38 in the middle. The steering device 20 comprises a rotation motor 54 which turns the carriage 22 about a horizontal axis Y according to fig. 1. The carrier 22 can be adjusted in the plane of the base 18 and, in addition, in the vertical direction to grasp and store the individual transition magazines 16. The corresponding X-Y slide or X-Y-Z slide can be designed in different ways. For example, a corresponding slider may be disposed on the rotating rod 56 between the bracket 22 and the rotating rod 56.

Alternatively, the rotary motor 54 can also be arranged on a slide, at least on a slide which is movable along an axis.

In any case, each transition magazine 16 with the delimiting means 38 is inserted into the adjacent receiving unit 14 with the other flat side facing upwards by the deflecting means 20, so that the end of the unprocessed bristle tuft protrudes upwards.

At the same time or after the transfer of the transition magazine 16, which has just been filled with bristle tufts, is then inserted into the free position in the right-hand receiving unit 14.

When at least the left-hand receiving unit 14 has been filled, preferably the right-hand receiving unit 14 has been completely refilled, the grinding device 24 is lowered again, so that all bristles of at least the left-hand receiving unit 14, preferably the receiving units 14 on both sides, are ground again and pointed bristle ends are obtained.

In the variant according to fig. 1, a plurality of carriers 22 is present, so that the transition magazine 16 is replaced, introduced and removed more quickly.

The two grinding devices 24 illustrated in fig. 2 can also be considered as one grinding device 24, since both grinding devices are on a common vertical adjustment mechanism. The grinding device 24 can optionally also be moved via a common drive. Alternatively, a continuous sanding belt can also be provided, with which all bristles of both receiving units 14 can be sanded simultaneously.

Yet another embodiment provides that one or more carriers 22 do not remove the transition magazine 16 from the receiving unit 14, but that the receiving unit 14 and the transition magazine 16 and the delimiting means 38 located therein are gripped, disengaged from the respective drive 52 and rotated through 180 °, and then the bristle ends which are not pointed are directed towards the grinding device and lowered again. The other end of the bristle tuft is then pointed.

Fig. 5 shows a variant of the grinding device 24. Here too, a circumferential grinding belt 26 is provided, which is guided over a plurality of deflection rollers 72, at least one deflection roller 72 of which is driven.

In the illustrated example, there are three turning rolls 72 (this is not to be construed as limiting), and thus the belt 70 in side view has a triangular curve. Between the two lower turning rollers 72, a sanding plane 74 or, more generally, a linearly moving and rotating sanding plane on the bottom surface of the sanding belt 26 is created.

The grinding device 24 is furthermore rotated via a drive 76 about a rotational axis C, which is preferably perpendicular to the grinding plane 74. The transition cartridge 16 and the axis of rotation X of the transition cartridge 16 are symbolically shown.
