BRUSH FILLING DEVICE

Description

[0001] The invention relates to a brush stuffing device, comprising at least one magazine in which bristles are positioned adjacent to one another, pre-tensioned towards an outlet area, a tuft separator which sweeps along the outlet area of ​​the at least one magazine with an outer edge and has at least one receiving opening in the outer edge for at least one tuft to be separated, a stuffing tool which receives separated tufts from the tuft separator and which can be moved back and forth between a stuffing position and a filling position. A drive system moves the tuft separator relative to the at least one magazine from a rear dead center, in which bristles are pressed from the magazine into the receiving opening, to a front dead center, in which the tuft is discharged towards the receiving opening. A controller controls the drive system.

[0002] DE 30 16 790 A1 shows such a brush stuffing device.

[0003] Such tuft stuffing devices, as shown, for example, in WO 2020 / 094782 A1, operate at extremely high cycle rates of 1,000 stuffing processes or more per minute. Depending on whether the brush to be produced is to consist of the same bristles or different ones, e.g., different colored or different lengths, one or more magazines are used, each containing a package of bristles. Then, between individual stuffing processes, it is necessary to switch to another magazine without reducing the cycle rate if tufts with different bristles need to be stuffed next. There are brushes that have three or more different types of bristles, e.g., toothbrushes with white, red, and blue bristles, with bristles of different lengths, or with sharpened and unsharpened bristles, or with bristles of different diameters.Bristles can also be made of different materials or have different cross-sections and be used in the same brush. When separating the tufts from the magazine, it is important that the bristles pressed together at the sides can always slide back in when another tuft of bristles has been removed. However, some kind of blockage or clogging can occasionally occur, i.e. there are areas throughout the magazine where the bristles are pressed together excessively and areas where the pressure between the bristles is too low. This can then result in too few bristles being pressed into the receiving opening. The bristles usually move into the receiving opening at the rear dead center of the tuft separator, when it is abruptly braked and even stops briefly.Then the relative movement between the tuft separator and the bristles in the magazine is small (in the final phase of braking) or even zero.

[0004] The object of the invention is to reduce the aforementioned uneven densities or pre-tensions of the bristles within the magazine and to significantly reduce or even eliminate the resulting downtimes of the brush stuffing devices.

[0005] This object is achieved by a brush stuffing device of the type mentioned above, wherein the drive system can adjust the relative position of the rear dead center to the at least one magazine such that the rear dead center can be located in different sections of the outlet area of ​​the magazine from which tufts are removed, and bristles can be removed from these different sections of the outlet area.

[0006] The drive system is therefore not only designed to switch from one magazine to an adjacent magazine when multiple magazines can be connected and / or to move the tuft separator, but also ensures that tufts are removed evenly across the length of the outlet area and not always at the same point. This, it has been discovered, allows the entire bristle stack in the magazine to be pre-tensioned more evenly, preventing bristle buildup in sections of the outlet area that were previously never located at the dead center.

[0007] A variant of the invention provides for several usable magazines arranged side by side, and the drive system can move the relative position of each magazine, when activated for tuft removal, relative to the tuft separator in the area of ​​the receiving opening at the rear dead center. The drive system can adjust the relative position so that the rear dead center can be located in different sections of the outlet area of ​​the activated magazine, and bristles can be removed from these different sections of the outlet area. The drive system is thus capable of positioning all of the activateable magazines relative to the tuft separator so that tufts can be removed from different locations in each magazine.

[0008] The term "switching on" means that tufts are taken from the magazine that is currently switched on. Therefore, if different bristles are taken from different magazines to produce a brush, the magazines are switched on one after the other.

[0009] Of course, it's also possible to have two magazines containing the same bristles. This would be the case, for example, if a toothbrush predominantly uses white bristles and very rarely uses other colored bristles. In that case, it makes sense to fill two or three magazines with white bristles and one with red bristles.

[0010] There are various ways to change the relative position of the dead center to the outlet area of ​​the magazine(s). This can be achieved by the drive system moving the magazine itself, i.e. the currently activated magazine from which tufts are removed, or by adjusting the rear dead center. In the first case, this means that the rear dead center of the tuft separator remains constant in space, but the magazine is moved to this dead center. In the second case, it means that the tuft remover is moved further or less and pivoted so that its rear dead center is adjusted in space and can therefore come to rest in different sections of the outlet area. The magazine therefore remains spatially fixed. Of course, a combination of both movements would also be possible.

[0011] The various positions together can cover at least 50% of the outlet area of ​​at least one magazine, or all magazines in the case of multiple magazines. Alternatively or additionally, the various positions together can cover at least 50% of the outlet area in each outer third of the outlet area. The receiving opening has a certain width, which consequently not only removes bristles at specific points, but also lies at the rear dead center over a section of the outlet area. If these various positions are added together, the receiving opening is located in sections that cover 50% or more of the outlet area.

[0012] As it turns out, clogging and bristle buildup are most likely to occur near the ends of each outlet area. For this reason, an alternative or addition to the above-mentioned approach is to ensure that 50% of each outer third of the outlet area, which then borders the respective edge of the magazine, is covered by the positions of the receiving opening. This ensures that tufts are continuously removed from these sections of the outlet area that are prone to clogging.

[0013] It may also be advantageous, for example, to remove no tufts at all in the middle third or very few compared to the outer thirds of the recording area.

[0014] Furthermore, it is optionally provided that the control system is configured to equalize the use of the various relative positions of one magazine, or in particular of each magazine in the case of multiple magazines, over several consecutive filling processes of multiple brushes. Therefore, the focus is not necessarily on ensuring that the relative positions are distributed as evenly as possible across the outlet area of ​​each magazine when filling a single brush. Rather, when using the brush filling device across multiple brushes, additional attention is paid to ensuring that the relative positions used are equalized.For example, if ten relative positions are possible in each magazine and only three tufts are removed per brush, positions 1-3 are not always approached each time a brush is loaded, but also positions 4-10. For example, positions 1-3 are used for the first brush, positions 8-10 for a subsequent brush, and later also positions 4-7. This sequence is purely exemplary.

[0015] "Compensation" does not necessarily mean that at the end of a magazine's use, each position actually occurs exactly as frequently as the other position, but it does prevent the positions from clustering.

[0016] According to another variant of the invention, the control system is designed such that, over several consecutive filling processes of several brushes, it utilizes the relative positions at the end sections of the outlet area of ​​at least one magazine more frequently than between them. As already explained above, with certain bristles or magazines, there may be an increased risk of blockages, particularly in the end sections of the outlet areas (in a plan view, at the left and right ends of the outlet area). This can be counteracted by using these end sections more often to remove tufts than between them over the entire use of the bristle package in the magazine.

[0017] The control system is preferably designed such that when a magazine is switched on again it moves to a different relative position than the last relative position of this magazine during the previous switch-on, in particular to an adjacent position. If, for example, a magazine is switched on again, for example because the last brush produced is finished or because, for example, switching to a different magazine is carried out and then the original magazine is returned to, the magazine is switched on again. Here it should move to a different relative position than the last relative position of this magazine. For example, if the previous brush was moved to relative position 6 during the last tamping process, the subsequent brush will move to position 7 or, generally speaking, a position other than position 6 when the same magazine is switched on for the first time.

[0018] A further variant of the invention provides for several adjacent magazines that can be switched on to dispense tufts. The control system is designed in such a way that it has a predetermined sequence of the relative positions of the magazines stored during the stuffing process and, after switching on another magazine and returning to a previously used magazine, moves to a relative position different from the last one reached with the previous magazine. In particular, this position is the next position in the predetermined sequence. In the previously mentioned example with 10 positions per magazine, the sequence is, for example, positions 1, 3, 2, 5, 4, 7, 6, 9, 8 and 10. The first use of the magazine then moves to positions 1, 3, 2, followed by a pause. This pause occurs, for example, when the next brush is stuffed or when the system returns to this magazine after using another magazine.When the first magazine is used again, position 5 is used first, then position 4, and finally position 7, etc. Even with very consistent and possibly branched use due to sequences of positions not directly adjacent to each other, this ensures that the selected sequence is maintained beyond a single use of the magazine when this magazine is subsequently activated. This ensures that the preload in the magazine is uniformed throughout the entire magazine's use.

[0019] However, the control system can also be designed so that the adjacent relative positions are traversed one after the other when one or more brushes are being loaded, in addition to a single use of at least one magazine. Single use in this context means that the magazine is switched off or the brush is fully loaded and use of the magazine for this brush is ended. In the given example, the adjacent relative positions are positions 1, 2 and further ascending up to position 10. These positions are traversed one after the other. For example, if the loading of a brush or the use of a magazine ends at relative position 7, the next use continues at position 8.

[0020] Under certain circumstances, it may be advantageous not to necessarily specify the immediately next position as the mandatory next position, but rather to allow a certain distance between the positions. To this end, the invention provides that the control system is designed such that relative positions are approached one after the other, with a maximum of two intermediate positions between them. This means that there is a certain range within which the next position lies. An example of this would be the consecutive positions 1, 4, 2, 3, 6, 7, 5, 8, 9 and 10. Overall, the relative position moves upwards in number from 1 to 10, although there are some intermediate positions, such as positions 3 and 5, which are temporarily numbered in descending order.

[0021] According to a further variant, these relative positions, with a maximum of two intermediate positions between them, can be defined not only for the individual use of a magazine (for example, if the bristle requires twenty tufts of a magazine), but also for the filling of one or more brushes. In the aforementioned example, this would mean that a first brush uses positions 1, 4, 2, and a subsequent brush uses positions 3, 6, 7.

[0022] Once an end position has been reached, so to speak - end position 10 in this example - there are two different strategies for how to proceed. Overall, an overall movement takes place from the first end section of the outlet area to an opposite second end section of the outlet area, albeit with certain possible steps back in the opposite direction (e.g. after position 4 back to position 2 and then again to positions 3 and 6). One option is to start the next stuffing process at the first end section again after reaching the second end section. Alternatively, the process can continue at the second end section and then move back to the first end section. Example: After reaching position 10, positions 9, 8, 5, etc. follow until position 1 is reached again.

[0023] While the term "end section" expresses that a section in the region of the actual end of the outlet area is meant, according to a further variant, the invention provides for relative positions in which the lateral ends of the outlet areas are actually reached through the receiving openings. These are the transitions of the outlet area to the side walls of the magazine or to a stripper.

[0024] Further features and advantages of the invention will become apparent from the following description and the accompanying drawings, to which reference is made. In the drawings: Figure 1 a schematic view of a brush stuffing device according to the invention, Figure 2 a schematic view of a second variant of the brush stuffing device according to the invention with several magazines, Figure 3a schematic representation of the pressure distribution within a magazine during a tuft removal at the right end of the magazine, Figure 4 a schematic representation of the pressure distribution within a magazine when removing a bunch of cartridges in the area of ​​the left magazine end, Figure 5 different relative positions between dead center and magazine, Figure 6 a schematic representation of ten different relative positions between dead center and magazine, and Figure 7 a schematic overview of a brush head with numerous holes for tufts and an associated brush stuffing device with three different magazines.

[0025] In Figure 1 a brush stuffing device 10 is shown, which has a stuffing tool 12 with a tip 14 and a stuffing tongue 16, which can be moved along a direction X towards and away from a brush body 18, here the brush body 18 of a toothbrush.

[0026] A symbolically represented tuft of bristles 19 is removed by a tuft separator 20 from a magazine 22 in which bristles 24 are arranged vertically and laterally pre-tensioned as a package. This package is mechanically pre-tensioned in the Y direction, for example, by a spring, pneumatics, or hydraulics.

[0027] The tuft separator 20 is a plate-shaped and sickle-shaped part that can be reversibly pivoted about an axis A by means of a drive 26. The pivot angle is adjustable by the drive 26.

[0028] Due to the pre-tension, the bundle of bristles is pressed toward an outer edge 28 of the tuft separator 20. The magazine 22 includes lateral boundaries 30 that extend toward the tuft separator 20. The area of ​​the magazine 22 adjacent to the outer edge 28 is open, so that the bristles of the bundle directly abut the outer edge 28 in this so-called outlet area 32.

[0029] In the area of ​​the outer edge 28 the tuft separator 20 has, this is in Figure 2 and the enlargement within the Figure 2 can be seen, a receiving opening 34 for bristles, which are pressed into this receiving opening 34 by the pre-tension of the package and then form a tuft to be separated.

[0030] This tuft 19 is transported by the movement of the tuft separator 20 to a lateral feed opening 36 of the stuffing tool 12, picked up there and moved by the stuffing tongue 16 through the tip 14 into the corresponding opening in the brush body 18.

[0031] Optionally, an adjustment drive 38 can be provided for the magazine 22, which can move the magazine 22 in the Z direction into different positions relative to the axis A and to the bunch separator 20.

[0032] The variant of the brush stuffing device according to Figure 2 essentially corresponds to the Figure 1, so that only the differences need to be discussed below. Instead of one magazine 22, three magazines 22, 22' and 22" are positioned next to one another. The magazines 22 to 22' can have different bristles, e.g. white, red and blue bristles and / or bristles of different lengths, different flexibility or even different geometries, e.g. with rounded ends or pointed ends. Each magazine 22 to 22" has its outlet area 32, wherein the outlet area 32 of the activated magazine (here magazine 22) is delimited by the outer edge 28, whereas the outlet areas 32 of the deactivated magazines (here 22' and 22") are defined by a limiter 40 which is vertically offset from the tuft separator 20.

[0033] In Figure 2 is the one in Figure 1omitted, so-called stripper 42 is shown, which extends from the switched-on magazine to the feed opening 36 and closes the receiving opening 34 in this area.

[0034] The wiper 42 can have a tip 44 which projects laterally from the boundaries 30 into the package of bristles 34.

[0035] The movement of the tuft separator 20 is in the present embodiments according to the Figures 1 and 2 on a circular path around the axis A. The tuft separator 20 thus has a front dead center, in which it delivers tufts 19 into the stuffing tool 12, and a rear dead center, which Figure 2 which is located in the outlet area 32.

[0036] The position of the rear dead center relative to the exhaust area 32 and thus to the magazine 22 to 22" can be varied in different ways.

[0037] On the one hand, the drive 26, which may also include cams, stops, etc., can vary the pivoting angle of the tuft separator 20, so that the tuft separator 20 pivots back more or less far from the stuffing tool 12 and can thus come to rest in different sections of the outlet area 32.

[0038] The second variant of how the relative position of the rear dead center to the magazine 22 to 22' can be varied is carried out via the adjustment drive 38, which can adjust the magazine(s) 22 to 22' relative to the tuft separator 20 and thus to the rear dead center.

[0039] A third variant involves a combination of the above movements.

[0040] At the rear dead center, the pre-tension of the package causes rear bristles to press the bristles in the outlet area 32 into the receiving opening 34.

[0041] The adjustment drive 38 can not only vary the position of the currently engaged magazine 22 to 22" relative to the rear dead center, but can also engage each magazine if multiple magazines are present. Bunches are then removed from the engaged magazine.

[0042] The drives 26, 38 responsible for varying the relative position of the rear dead center to the tuft separator 20 form, individually or together, a drive system for this relative adjustment. It should be emphasized that the adjustment drive 38 does not necessarily have to be a single, isolated drive, but can be composed of several drives, each of which is individually responsible for switching on the magazines or individually for adjusting the relative position of the rear dead center to the tuft separator within each magazine 22 to 22".

[0043] Optionally, for example, the magazine can be engaged solely via the adjustment drive 38, and the relative displacement of the rear dead center relative to the engaged magazine can be effected via the drive 26. Alternatively, the drive 26 and the adjustment drive 38 can also work together to change the relative position. Finally, the adjustment drive 38 could be provided both for engaging the respective magazine 22 to 22" and for adjusting the relative position, so that the drive 26 does not have to set different pivot angles.

[0044] In the Figures 3 and 4The pre-tensions between adjacent bristles and, so to speak, the concentration and density of the bristles within the respective magazine, here magazine 22, are shown. In both variants, as has been customary in the prior art, only the same relative position of the rear dead center to the magazine 22 and thus to the outlet area 32 is always approached. Figure 3 the position of the rear dead center is always at the right end of the exhaust area 32, whereas in Figure 4 always at the left end near the stripper 42. It can be seen that the bristles are then always concentrated at the opposite end, which can lead to extreme compaction or a type of blockage. This means that in these areas, a steady increase in force occurs, and the bristles become increasingly fixed in position, meaning that no movement occurs here. This becomes increasingly detrimental to the removal of tufts the longer the brush tamping device runs.

[0045] To prevent this, the aforementioned drive system is used, which positions the rear dead center at different sections of the outlet area 32, so that tufts are continuously removed from these different sections. For example, a relative position of the receiving opening 34 to the outlet area 32 can be located on the far left, i.e., close to the wiper 42, approximately in the middle of the outlet area 32 or at the end of the outlet area 32 remote from the wiper 42. The three different variants according to Figure 5 even show that the receiving opening 34 can actually be located at the lateral ends of the outlet areas 32 (left and right illustration in Figure 5 ).

[0046] While the variant according to Figure 5 In each third of the exhaust area (left, middle and right) a relative position of the rear dead center is provided, in the variant according to Figure 6Ten different relative positions are possible. Position 1 and position 10 may be located directly at the respective lateral end of the outlet area 32, but they are Figure 6 slightly spaced therefrom, ie they are located in a respective end section of the outlet area 32.

[0047] Figure 7 shows the head of a toothbrush with a total of 38 different openings that are filled with bristles. The lines between the individual openings indicate the order in which bristles are filled.

[0048] Three different types of bristles are used for the toothbrush, from the 22" to the 22" magazine. For example, the bristles have different colors.

[0049] The order in which the bristles are filled depends on various factors, but in the variant shown, it is not selected in such a way that all holes are filled first, receiving the bristles from magazine 22, and then, so to speak, all from magazine 22', and then finally all from magazine 22". In view of the extremely high cycle rates, it is necessary that those holes that are close to one another are filled one after the other, so that the movement of the brush body between the individual cycles is as small as possible. This means that it is necessary to change the magazine between successive cycles and to switch on a different magazine.

[0050] In this example, tufts from magazine 22 are used to fill openings 1 to 3, 8 to 11, 17 to 19, and 25 to 31. Openings 4 to 7 and 32 to 38 are filled with tufts from magazine 22', and openings 12 to 16 and 20 to 24 are filled with tufts from magazine 22".

[0051] The removal of the individual tufts is carried out in such a way that different sections of the outlet areas 32 are located at the rear dead center and thus there is no accumulation or clogging within the package of tufts in the respective magazine 22 to 22".

[0052] Various variants are possible, some of which can be combined with each other, and are presented below.

[0053] A controller 50 is coupled to the drive system and thus to the drive 26 and to the adjustment drive 38. The controller 50 can store various variants of the sequence of the relative positions of the rear dead center in the respective exhaust region 32 and, so to speak, moves through these positions one after the other and knows which previous position was moved to.

[0054] The control 50 is designed such that it evens out the use of the different relative positions of the magazines 22 to 22" over several consecutive filling processes, not just by one brush, but by several brushes. This means that for each magazine 22 to 22", different sections of the respective outlet area 32 are covered evenly.

[0055] Alternatively, it may be advantageous to access the end sections more frequently, i.e., to use them more intensively than a middle section, since there is a higher risk of bristle "piling up" in the end sections. For example, it may be provided that tufts are removed less frequently in the middle third, relative to the length of the outlet area 32, than in each of the end areas, i.e., in their thirds. These thirds are referred to as the outer thirds.

[0056] The control 50 knows the last position reached in each magazine 22 to 22", even after the magazine has been switched on again. For example, if for holes 1 to 3 the positions 1 to 3 in magazine 22 (see Figure 6 ), then later, when holes 8 to 11 need to be plugged, the process will not start again with position 1, but rather positions 4 to 7 will be approached.

[0057] This means that the last relative position (here position 3) is not approached when the magazine is switched on again, but another position, in particular a neighboring position.

[0058] However, it is not necessary to move directly to the adjacent position; it is also possible to move to positions that are nearby and have a maximum of two intermediate positions between them. For the example, Figure 7 For holes 1 to 3, the magazine 22 would be moved to positions 1, 4, 3 and then for holes 8 to 11 to positions 7, 5, 8 and 6. For the following holes 7 to 19, positions 9, 10 and then again 1 etc. would have to be approached.

[0059] If a predefined sequence of positions is saved, this sequence will be followed in this sequence even after a single use of the magazine (i.e., after filling holes 1 to 3 and after stuffing a brush), and also during subsequent use, e.g., for brushes to be stuffed subsequently, so that a predefined use of the various sections of the respective outlet area 32 of each magazine 22 to 22' is ensured throughout the processing of the entire package of bristles 24. Therefore, in this variant, the stuffing of each brush does not begin again from the starting position, e.g., at position 1, but rather, attention is paid to the position in which the magazine was last used, and the sequence is then continued.

[0060] The specified sequence does not have to be designed in such a way that positions 1 to 10 ascend continuously or on average (based on the numbering) and then start again with position 1 or a position close to 1. This is possible, but it is also possible to move in a zigzag manner with regard to the numbering of the positions after reaching an end range, e.g. at position 10, in a continuous reverse sequence or an appropriately adapted sequence to the opposite end range, without jumping to this opposite end range. In a sequence without jumps, i.e. from 1 to 10, after reaching position 10, position 9 and thus position 8 and so on would be approached.

[0061] A variant of the invention provides that the various positions together cover at least 50% of the outlet area 32 of the magazine(s) 22 to 22' and / or the various positions together in each outer third of the outlet area cover at least 50% of this outlet area 32. In other words, the receiving opening 34 has a certain width that covers a small section of the respective outlet area 32 at the rear dead center. If all positions of the receiving opening 34 at the rear dead center are added together, this accumulated distance is 50% of the total distance of the outlet area 32, i.e., the area over which the bristles press against the tuft separator 20 and would, so to speak, emerge from the magazine 22 without the tuft separator. This applies correspondingly to the outer thirds.

[0062] Depending on the type of bristle and magazine geometry, there may even be no removal in the middle third.
