Description

[0001] The invention relates to a dividing device for separating bristle bundles from a bristle supply, comprising a divider which has a plurality of bundle receiving notches radially incorporated into the outer surface on an outer surface curved along a circular arc and which is pivotable about a pivot axis between a bundle receiving position on a bristle supply and a bundle delivery position at a downstream station, in particular a transport device for conveying separated bristle bundles, and with an ejection device for ejecting bristle bundles positioned in the bundle receiving notches.

[0002] Furthermore, the invention also relates to a brush manufacturing machine, in particular for anchorless fastening of bristle bundles in brush bodies, with a dividing device.

[0003] Such compartment devices and such brush manufacturing machines are known from the prior art in various embodiments.

[0004] German patent application DE 100 62 398 C5 discloses a method for forming a bristle bundle, in which a receiving device is moved past at least one filament container, in which bristle filaments contained in the filament container are picked up and fed to a removal device. DE 100 62 398 C5 further discloses a device for forming a bristle bundle with a rotatably mounted receiving device, the outer circumferential surface of which seals at least one filament container and has at least one bristle filament receptacle, and which is movable from a first position, in which the bristle filament receptacle communicates with a filament container, to a second position for removing a bristle bundle formed by the bristle filaments contained in the bristle filament receptacle.To reduce the stress on the device and the noise associated with carrying out the method, it is proposed that the receiving device be driven in a continuous, unidirectional rotation. With regard to the method, DE 100 62 398 C5 proposes that the receiving device be rotated continuously.

[0005] Document DE 40 40 297 C2 discloses a brush manufacturing machine with a bristle feed from a bristle supply to a brush body or the like, wherein the brush manufacturing machine has a bundle divider arranged at the bristle supply for removing bristle bundles from the bristle supply, to which an intermediate conveying device is assigned, which has a rotatably mounted circular disk that has edge-open bundle receiving openings for individual bristle bundles located on the outer edge.The brush manufacturing machine is characterized in that a slide is provided at a transfer point between the bundle divider and the circular disc for transferring an unfolded bristle bundle from the bundle divider to the circular disc, that an outer edge cover, which closes the bundle receiving openings on the outside, is arranged between the transfer point for the bristle bundles conveyed by the bundle divider and the removal point, that a removal device for the bristle bundles is provided at a removal point, which has an ejection device with an ejector that can be inserted approximately axially parallel into the receiving openings of the circular disc, and that a brush body or a perforated plate for receiving the ejected bristle bundles can be positioned at the removal point.

[0006] German patent application DE 197 45 024 A1 discloses a brush manufacturing machine with a multi-stage magazine. The magazine has several feed channels, defined by side guides, with discharge ends for feeding bristle bundles from different bristle stores to a bundle divider with a divider notch for a packing tool. An intermediate conveying device is arranged between the discharge ends of the magazine feed channels and the bundle divider. This intermediate conveying device has at least one receptacle for individual bristle bundles, which can be selectively assigned to the discharge ends of the individual feed channels. The receptacle(s) of the intermediate conveying device can be positioned at the bundle divider for transferring the received bristle bundles.

[0007] In brush manufacturing machines used to produce toothbrushes with anchorless technology, bristle filaments stored in a bristle magazine, also known as a material box, are taken from the bristle supply by means of a divider. The divider has several bundle-receiving notches along part of its circumference. The bristle magazine comprises a channel in which the individual bristle filaments are loosely arranged. These can be pressed against the divider by means of a material pusher or bristle pusher. When the divider is passed by an open side of the channel, the bristle filaments are pressed against an end face of the divider, where the bundle-receiving notches are located.The size of the bundle receiving notches essentially determines the total number of bristle filaments that are separated and combined into a bristle bundle, and thus ultimately also the size of the bristle bundle in the brush to be manufactured.

[0008] Once the divider has reached its bundle discharge position at a downstream station, the bristle bundle located in at least one bundle receiving notch must be transferred to downstream production stations.

[0009] In previously known partitioning devices, the bristle bundles are pressed out of the bundle-receiving notches of the partition by means of a so-called pusher disc. The pusher disc is moved in a linear motion transverse to the longitudinal direction of the individual bristle filaments and transverse to the partition (cf. Fig. 1 and Fig. 2) This causes the bristle bundles to be pushed out of the bundle-receiving notches. Especially if the divider is a rotatable dividing disc with a round outer contour in which several bundle-receiving notches are formed, problems can arise when the bristle filaments are pushed out of the radially arranged bundle-receiving notches in the outer edge area of ​​the dividing disc.

[0010] It can happen that bristle filaments get caught on the edges of external bundle-holding notches during the squeezing process, meaning that not all bristle filaments located within these notches can be fed to a subsequent processing step or station. Furthermore, bristle filaments remaining on the divider can cause disruptions in the subsequent squeezing process. A non-radial, but parallel, arrangement of several bundle-holding notches in a divider would facilitate linear squeezing in one direction of movement. However, this approach would have several disadvantages. Firstly, depending on their position on the circumference of the divider, the bundle-holding notches would have different geometries while maintaining the same fill area. This would be particularly noticeable if the divider is a circular squeezing disc.Reproducible filling of the individual bundle-receiving notches adjacent to the channel of the previously described bristle magazine would therefore be virtually impossible. On the other hand, the individual bundle-receiving notches of such a divider would have to be designed taking into account their arrangement on the divider. This would involve a considerable increase in design effort.

[0011] The object of the invention is therefore to create a dividing device and a brush manufacturing system of the type mentioned above, with which the aforementioned disadvantages in dividing bristle bundles from a supply of loose bristle filaments can be avoided or at least reduced.

[0012] To solve this problem, a partitioning device of the type mentioned at the outset is proposed, comprising the means and features of the independent claim directed to the partitioning device. In particular, to solve the problem, a partitioning device of the type mentioned at the outset is proposed, in which the ejection device is configured to move at least two contact areas of the ejection device, which act upon bristle bundles during the ejection process, in ejection directions oriented differently relative to each other with respect to the axis of rotation of the partition, in order to eject bristle bundles from bundle-receiving notches of the partition. In this way, the contact areas can be moved with ejection movements coordinated with the position and orientation of at least two bundle-receiving notches. This allows at least two of the bundle-receiving notches of the partition to be emptied more efficiently and precisely.

[0013] In other words, it is possible to use the ejection device to laterally eject a bristle bundle positioned in at least one bundle receiving notch, with the divider in the bundle delivery position, over the open edge of at least one bundle removal notch, from the bundle receiving notch and transversely or perpendicularly to the longitudinal extent of the bristle bundle and / or the individual bristle filaments.

[0014] It can be particularly advantageous if the extrusion directions of the at least two contact areas are radially oriented with respect to the curved outer surface of the divider.

[0015] During the extraction process, the extraction device can exert an extraction force radially oriented with respect to the curved outer side of the divider on each bristle bundle positioned in at least two of the bundle receiving notches, so that the bristle bundles can be extracted from the bundle receiving notches in a radial or nearly radial direction transversely or perpendicular to the longitudinal extent of the bristle bundles.

[0016] The divider may be a preferably circular, rotatable partition disc about its axis of rotation. To generate the pivoting or rotating movement of the divider, which is particularly circular, the partitioning device may include a drive device. This drive device may be called a rotary drive device and may be configured to pivot or rotate the divider. In this way, the divider can then be moved between the bundle receiving position and the bundle discharge position by means of the drive device of the partitioning device.

[0017] In one embodiment of the dividing device according to the invention, the at least two contact areas can be arranged on a common pressure element of the ejecting device that is movable with the ejecting device.

[0018] In another embodiment of the dividing device according to the invention, at least one contact area of ​​the at least two contact areas can be arranged on a first pressure element movable with the ejection device and at least one further contact area of ​​the at least two contact areas can be arranged on a further pressure element of the ejection device movable with the ejection device.

[0019] The pressure element or elements can be moved by means of the ejection device in ejection movements relative to the divider and the bundle receiving notches, either transversely or perpendicularly to the axis of rotation of the divider.

[0020] The ejection device can therefore comprise at least two or three, or even more, such pressure elements. One of the pressure elements may be assigned to only one bundle-receiving notch. However, it is also possible for one of the pressure elements to be assigned to several bundle-receiving notches, so that the previously described relative movement of the corresponding pressure element to the divider and to the bundle-receiving notches is used to eject the bristle bundles arranged in the bundle-receiving notches in a radial direction, or at least in an almost radial direction.

[0021] To set the pressure element(s) in motion, the ejector device can have at least one ejector drive. Each pressure element can be assigned its own ejector drive. However, it is also conceivable to assign one ejector drive to two or more, or even all, of the pressure elements of the ejector device.

[0022] The partitioning device can include a counter-holding device. This counter-holding device can have at least one counter-holder that is associated with, for example, the at least one pressure element of the ejection device mentioned above, and can be moved in a counter-holder movement directed transversely or perpendicular to the partitioner, coordinated with the ejection movement of the pressure element and / or at least one contact area of ​​the at least two contact areas. The movements can be coordinated such that the distance between the at least one counter-holder and the at least one pressure element remains constant or is reduced. The counter-holder can be used to transfer the bristle bundles, which have been ejected from the bundle-receiving notches by means of the at least one contact area and / or pressure element, into a transfer position for a downstream station.This downstream station can, for example, be a transport device for conveying the bristle bundles taken from the bundle receiving notches.

[0023] In one embodiment of the partitioning device according to the invention, the ejection device may have two actuating bars as pressure elements, each pivotable about a pivot axis. The pivot axes of the two actuating bars may be spaced apart from the axis of rotation of the partition. Each of these actuating bars has a section designed to eject bristle bundles from bundle-receiving notches on the partition and pivotable past it for this purpose. Each of the bar sections may have an end face on which at least one of the at least two contact areas is formed. Preferably, in their initial position, the end faces of the bar sections each extend along a circular arc that is parallel to the curved outer surface of the partition.In this way, the section of the bar, bent along a circular arc and thus having a smaller radius than the curved outer surface of the divider, can be guided along the divider, particularly along a flat side of the divider, from behind past several bundle-receiving notches in a pivoting motion directed away from the divider's axis of rotation, in order to express bristle bundles positioned in the bundle-receiving notches. The at least one contact area on one section of the bar is moved in a different expressing direction than the at least one other contact area on the other section of the bar.

[0024] The curved end face of a strip section can be bent by a radius corresponding to the radius of an imaginary arc connecting several of the bundle-receiving notches at their base. In the initial position of the respective strip section, i.e., before it is pivoted to expel the bristle bundles positioned in the bundle-receiving notches, the curved end face of the strip section can then rest tangentially against several bundle-receiving notches, so that bristle bundles positioned therein can be simultaneously pushed out of the bundle-receiving notches when the push bar is pivoted. The pivot axes of the push bars can advantageously be aligned parallel to the axis of rotation of the divider.

[0025] In another embodiment of the dividing device according to the invention, the ejection device may include a holder, a pusher, and an elastically deformable pressure element. This elastically deformable pressure element may, for example, be a pressure bellows and / or a pressure hose, preferably made of plastic, rubber, or synthetic rubber. The at least two contact areas may be formed on an end face of the elastic pressure element, which faces the bundle-receiving notches in the initial position of the elastic pressure element. Furthermore, the ejection device of this dividing device according to the invention includes a holder and a pusher with which the pressure element can be deformed.The holder has a contact surface as an abutment for the elastically deformable pressure element, against which the pressure element can rest and which is preferably curved along a circular arc parallel to the circular arc of the outer side of the divider. The pressure element can then be deformed by the pusher and by the contact surface acting as an abutment in such a way that the end face of the elastically deformable pressure element facing the bundle-receiving notches in its initial position, on which the at least two contact areas are formed, is pushed past the bundle-receiving notches by the deformation, preferably uniformly radially. This allows bristle bundles located in the bundle-receiving notches to be expressed out of the bundle-receiving notches in a radial or at least nearly radial direction.

[0026] In another partitioning device according to the invention, the ejection device can have several push pins as a pressure element. At least one of the at least two contact areas is formed on the head sides of the push pins facing the bundle receiving notches. The push pins can each be assigned to at least one bundle receiving notch or to several bundle receiving notches. With the ejection device, they can be moved in ejection movements oriented differently relative to each other, whereby the contact areas formed on their head sides are also moved in differently oriented ejection movements. It can be particularly advantageous if each bundle receiving notch is assigned such a push pin. In this way, the bristle bundles can be ejected radially from all bundle receiving notches of the partitioner that are in the dispensing position.

[0027] It can be advantageous if the ejector device has a pin guide for the multiple push pins and a pin slide. This pin slide can be moved linearly relative to the divider and also has a guide groove. The push pins can each have a guide roller that can be arranged in this guide groove. The guide groove can then serve as a control cam, with which the linear movement of the pin slide can be converted into different ejection movements of the push pins. In this way, the linear movement of the pin slide can be converted into differently oriented radial ejection movements of the push pins with the help of the guide groove and the guide rollers of the push pins.In order to compensate for differing feed rates of the individual push pins depending on the position of the push pins on the push pin slide, it may be advantageous if the push pins are spring-loaded push pins with a stop and / or if the guide groove is designed in such a way that a displacement of the push pin slide relative to the divider results in identical feed rates of several or all push pins.

[0028] In yet another embodiment of the partitioning device according to the invention, the pressure element can be a plate-shaped spring element. This can comprise a base spaced apart from the partition and a plurality of spring fingers directed radially outwards from the base and angled relative to this direction of the partition, serving as pressure elements of the ejection device. The spring element can be arranged relative to the partition such that, by approaching the base and the partition, the spring fingers perform differently oriented ejection movements, in particular radially oriented ejection movements with respect to the curved outer surface of the partition, to empty the bundle receiving notches.

[0029] Depending on the embodiment of this compartment device, the disc-shaped spring element can be a fixed spring element or rotatable about an axis of rotation of the compartment. Preferably, the spring element can then rotate around the axis of rotation of the compartment along with it.

[0030] The partitioning device according to the invention can include a bristle magazine with a bristle pusher. With this bristle pusher, a supply of loose bristle filaments arranged in the bristle magazine can be pushed towards the dispensing position, in particular against the partition. Using this bristle pusher, the several bundle-receiving notches arranged on the outer circumference of the partition can then be filled with bristle bundles.

[0031] The partitioning device according to the invention also includes a transport device for conveying separated bristle bundles. This transport device comprises a hose holder on which a number of transport hoses corresponding to the number of bundle-receiving notches on the partitioning device are arranged for conveying bristle bundles. The transport hoses can be attached to the hose holder by means of hose sleeves. The transfer of bristle bundles expressed from the bundle-receiving notches to the transport device can be facilitated if the hose holder is connected to a counter-holder of the partitioning device, for example, the counter-holder already mentioned, and can move with it.

[0032] The aforementioned problem is also solved by a brush manufacturing machine of the type mentioned at the outset, incorporating the means and features of the independent claim directed to the brush manufacturing machine. In particular, a brush manufacturing machine of the type mentioned at the outset, comprising a dividing device according to the invention, is proposed to solve this problem.

[0033] Exemplary embodiments of the invention are described in more detail below with reference to the drawings. These are shown in a partially schematic representation.

[0034] In the following description of various embodiments of the invention, elements that are functionally identical are given the same reference numbers even if they differ in design or shape.

[0035] The Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13 to Fig. Figure 14 shows a partitioning device designated as a whole by 1 for partitioning bristle bundles 2 from a bristle supply 3 with a partitioner 5, which has an outer surface 6 curved along a circular arc and a plurality of bundle receiving notches 7 radially inserted into the outer surface 6.

[0036] The Fig. 1, Fig. Figures 1a and 2, 2a show a brush manufacturing machine 4 which has a partitioning device as is known from the prior art. This partitioning device, known from the prior art, is associated with the disadvantages mentioned at the outset.

[0037] Instead of the compartment device known from the prior art, one of the devices described in the Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13 to Fig. 14 illustrated compartment devices 1 in the Fig. Brush manufacturing machine 4 shown in 1 to 2a can be used.

[0038] The dividers 5 of the divider devices 1 according to the invention can be pivoted about a rotational axis R of the divider 5 between a bundle receiving position adjacent to the bristle supply 3 and a bundle discharge position at a downstream station 8. At the station 8 of the in the Fig. The brush manufacturing machine 4 shown in 1 to 2a is a transport device 8 for forwarding separated bristle bundles 2 to downstream work stations.

[0039] The compartment devices 1 also each have an ejection device 9 for ejecting bristle bundles 2 positioned in the bundle receiving notches 7.

[0040] Each of the ejection devices 9 is designed to move, for example, two contact areas 10 of the ejection device 9, which bear bristle bundles 2, in relation to the rotation axis R of the divider 5 in ejection directions oriented differently to each other, in order to eject bristle bundles 2 from bundle receiving notches 7 of the divider 5.

[0041] In the exemplary embodiment of the compartment device 1 according to the Fig. 5 and Fig. 6 and 10 to 13 define the extrusion directions of the at least two contact areas 10 with respect to the curved outer surface 6 of the divider 5 as radially oriented, so that the bristle bundles 2 positioned in the bundle-receiving notches 7 are subjected to a radially oriented extrusion force and can be extruded from the bundle-receiving notches 7. This prevents the bristle bundles 2 from becoming caught on the edges of the bundle-receiving notches 7 during extrusion, thus avoiding the loss of individual bristle filaments or the retention of individual bristle filaments within the bundle-receiving notches 7.

[0042] For all compartment devices 1, as described in the Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13 to Fig. As shown in Figure 14, the dividers 5 are each designed as circular divider discs rotatable about the axes of rotation R. The divider devices 1 also each have drive devices 11 for pivoting or rotating the dividers 5. This allows the dividers 5 to be pivoted or rotated between the bundle receiving position adjacent to the bristle supply 3 and the bundle discharge position adjacent to the downstream station 8, in order to bring the bundle receiving notches 7 into the required position for receiving bristle bundles 2 and for discharging bristle bundles 2.

[0043] In the exemplary embodiment of a compartment device 1 according to the Fig. 11, Fig. 12, Fig. 13 to Fig. 14. The at least two contact areas 10 are arranged on a common pressure element 12 of the ejection device 9, which is movable with the ejection device 9. In the other embodiments of compartment devices 1 according to the Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 to Fig. It is provided that at least one contact area 10 of the at least two contact areas 10 are arranged on a first pressure element 12 movable by the ejector 9, and at least one further contact area 10 of the at least two contact areas 10 are arranged on a further pressure element 12 of the ejector 9 movable by the ejector 9. In order to be able to actuate the pressure elements 12, the ejector 1 has an ejector drive 9a.

[0044] The compartment device 1 also has a counter-holding device 13. Such a device is included in the Fig. Figures 1 to 2a illustrate the counter-holding device 13, which comprises at least one counter-holder 14 that is assigned to one of the existing pressure elements 12 and can be moved in a counter-holder movement oriented transversely or perpendicularly to the divider 5, coordinated with the ejection movement of the pressure element 12. The counter-holder 14 prevents the bristle bundles 2 from being lost during ejection with the aid of the respective pressure element 12. The movement of the counter-holder 14 can be coordinated with the ejection movement of the respective pressure element 12 to which the counter-holder 14 is assigned, such that the distance between the counter-holder 14 and the pressure element 12 remains constant or is reduced during the ejection process.

[0045] In the exemplary embodiment of the compartment device 1 according to the Fig. 3 and Fig. Figure 4 provides that the ejection device 1 has two actuating bars 15 as actuating elements 12, each pivotable about a pivot axis S spaced apart from the rotation axis R of the divider 5. Each actuating bar 15 is provided with a bar section 16 which can be pivoted past the divider 5 to eject bristle bundles 2 from bundle receiving notches 7 of the divider 5. The bar sections 16 each have end faces 17 which extend along a circular arc that, in the initial position of the respective bar section 16, is arranged or aligned parallel to the curved outer surface 6 of the divider 5. At least one contact area 10 of at least two contact areas 10 is formed on the end face of each of the two bar sections 16.

[0046] In the exemplary embodiment of the compartment device 1 according to the Fig. 11, Fig. 12, Fig. 13 to Fig. Figure 14 provides that the ejection device 9 has an elastically deformable pressure element 18 as a pressure element 12. This elastically deformable pressure element 18 is, for example, a pressure bellows or a pressure hose, which may be made of plastic, rubber, synthetic rubber, or other suitable materials. At least two contact areas 10 are arranged on an end face 19 of the elastically deformable pressure element 18 facing the bundle receiving notches 7. These contact areas are movable in different ejection directions. The ejection device 1 has a holder 20 with a contact surface 21 as a support for the pressure element 18 and a pusher 22 with which the elastic pressure element 18 can be deformed. This is done by moving the pusher 22 past the holder 20 in the direction of the divider 5.This causes the elastically deformable pressure element 18 to be compressed in such a way that, due to the holder 20, it only deflects in a radial direction, i.e., away from the axis of rotation R of the divider. This is possible because the contact surface 21 of the holder 20 is curved along a circular arc parallel to the curved outer surface 6 of the divider 5. The elastic pressure element 18 can be deformed by the pusher 22 and the contact surface 21 such that the end face 19, facing the bundle receiving notches 7 in its initial position, with its at least two contact areas 10, is pushed radially past the bundle receiving notches 7 in the extrusion direction by the deformation.

[0047] In the exemplary embodiment of a compartment device 1 according to the Fig. 5 and Fig. Figure 6 provides that the ejection device 9 has several push pins 23 as pressure elements 12. In the present embodiment, each of the 12 bundle receiving notches 7 is assigned such a push pin 23. At least one contact area 10 is formed on the head sides 24 of the push pins 23 facing the bundle receiving notches 7. The push pins 23 can be moved by the ejection device 9 in ejection movements oriented differently relative to each other. The different ejection movements of the push pins 23 are oriented such that the contact areas 10 on the head sides 24 of the push pins 23 can be moved radially or at least almost radially past the curved outer surface 6 of the divider 5 to empty the bundle receiving notches 7. This facilitates residue-free and minimally disruptive emptying of the bundle receiving notches 7.

[0048] The Fig. 5 and Fig. Figure 6 shows that the ejector device 9 comprises a pin guide 25 for the twelve push pins 23. The push pins 23 are guided in this pin guide 25 such that they can each be moved in a radially oriented ejection movement relative to the curved outer surface 6 of the divider 5. Furthermore, the ejector device 9 of this divider device 1 has a pin slide 26. This pin slide 26 is displaceable relative to the divider 5 and includes a guide groove 27 in which the push pins 23 are arranged with their associated guide rollers 23a. The guide groove 27 serves as a kind of control cam, which translates the movement of the pin slide 26 into the desired ejection movement of the individual push pins 23. The push pins 23 can be designed as spring-loaded push pins 23 with a stop.Thus, depending on the position of the individual push pins 23 on the pin slide 26, different ejection paths can be compensated for, if necessary. It is also possible that the guide groove 27 is designed such that a displacement of the pin slide 26 relative to the divider 5 results in identical advances of all push pins 26, so that several or even all bundle receiving notches 7 of the divider 5 can be emptied equally well and reliably.

[0049] In the embodiment of the compartment devices 1 according to the Fig. 7, Fig. 8, Fig. 9 to Fig. Figure 10 provides that the ejection device 9 comprises a disc-shaped spring element 28. This disc-shaped spring element 28 has a base 29 spaced apart from the divider 5 and a plurality of spring fingers 30, directed radially outward from the base 29 and angled relative to the base 29 in the direction of the divider 5, serving as pressure elements 12. The spring element 28 is arranged relative to the divider 5 such that the spring fingers 30 perform differently oriented ejection movements as the base 29 approaches the divider 5, essentially radial ejection movements with respect to the curved outer surface 6 of the divider 5.
