    The invention relates to a method and a device for adjusting a pusher (a tongue) forming part of a filling tool of a brush filling machine, is longitudinally slidably mounted in the lining tool and is removably and longitudinally adjustable connected to a stroke drive.
    With the pusher or tongue of a packing tool, a tuft of bristles is brought into a hole of the brush body together with an anchor or buckle serving as a fastening means. The position of the pusher in its front dead center must in this case be precisely adjusted. If the pusher comes too far forward, it pushes indirectly through the attachment means on the filaments of the folded pile of hair lying in front of it so that there is a risk that individual filaments are cut or cut and that the tufts of hair fall in later use, which is not acceptable especially for toothbrushes. If, on the contrary, the pusher does not advance far enough, the tuft of hair is not sufficiently pressed into the hole so that there remains a gap between the tuft and the bottom of the hole and between the tuft and the securing means and that individual filaments or tufts of whole bristles can easily be removed.
    Since a pusher wears or can also break, it is necessary from time to time to adjust the pusher again or to completely replace it. To simplify this positioning of the pusher for the inexperienced staff, various auxiliary devices have already been created. For example, DE 43 24 249 A1 discloses a device with which the pusher is fitted in its front dead center against an adjustment stop. This adjustment stopper is formed by a bristle body which is milled on the side of the holes and is covered with a plate, the plate having a thickness which corresponds to the material of the brush body removed by milling. The closed surface of the plate prevents the pusher from inadvertently entering a hole during adjustment, and is therefore not exactly positioned.
    The problem in this case lies in the fact that for each different brush body to garnish, it is necessary to manufacture an adjustment stop which is specific to it, which is related to corresponding efforts. In addition, it is not possible or possible only with considerable effort to change the depth of penetration of the pusher for testing purposes to be able to evaluate the result of the lining with different penetration depths of the pusher.
    Therefore, the problem is to create a method and a device of the type mentioned at the beginning with which a simple and precise adjustment and adjustment of the pusher are possible. In addition, a simple and definite modification of the adjustment position of the pusher must be possible.
    The solution according to the invention to this problem consists, as far as the method is concerned, in that the pusher travel drive is positioned in a predefined reference position or can be predefined in the momentary stopping region of the pusher. the packing tool in its forward dead center, in that the pusher is then adjusted with respect to its stroke drive in the longitudinal direction on an abutment element which can be positioned in front of the packing tool and in that finally, the pusher and his race training are connected to each other.
    The race training performs from the reference position a defined movement of residual race until it reaches its dead point before. If the pusher is manually adjusted to the stop member positioned in a defined position and is connected to the stroke drive in this position, the pusher also performs thereafter, after removing the stop member and set in motion stroke training, an axial movement of a defined extent to arrive exactly in the position of the desired forward dead center of the pusher. The adjustment and adjustment of the pusher are precise and simple to perform even for inexperienced staff.
    When for test purposes, the depth of penetration of the fastening means must be changed to optimize the pulling force for the tuft of bristles, it is necessary to move the neutral point before the pusher. For this purpose, it is appropriate for the stroke travel drive to be positioned from the reference position into a modified reference position so that the pusher is adjusted relative to its stroke drive in the direction of travel. the length on a stop element can be positioned in front of the lining tool and finally, the pusher and its stroke drive are connected to one another.
    If, for example, the reference position is moved backwards, that is to say that the running drive is stopped earlier than the initial reference position, the pushbutton is then moved thereafter over a longer length by the stroke drive, the forward dead center of the pusher is therefore further forward and the fastener penetrates deeper into the brush body.
    The change of the reference position can take place directly in degrees of the stroke training designed with a rotary eccentric. It is however more convenient to calculate the angular position of the stroke drive in one unit of length for the stroke travel length, preferably in tenths of a millimeter, since this represents a clearer magnitude for the user and a direct calculated correlation between the angular position and the stroke length is given.
    When the pusher wears or is damaged, it is replaced and a new pusher is newly adjusted as previously described. In the event of minor wear or damage, the pusher can also be ground and then continue to use. The dismantling of the pusher and its new assembly, however, take time.
    An idea of the invention which goes further therefore provides that before the adjustment of the pusher, described above, the pusher travel drive is positioned in a rear reference position within the momentary stopping region. of the packing tool in its rear dead point in which the free end of the pusher protrudes from the free end of the packing tool and that, in this position, the free end of the pusher is ground and / or milled . In this rear reference position of the pusher and the packing tool, there is sufficient space between the free end of the pusher and the packing site in which a brush body to be filled is arranged to position in front of the pusher a suitable machining device for grinding and / or milling. A pusher for fixing tufts of bristles with loops of circular section wire has at its free end a cavity with which the loop is guided. A pusher provided for this purpose is first ground, as a pusher for fixing anchors, perpendicular to its longitudinal axis and the cavity is then milled.
    In case of greater damage to the tip of the pusher, a piece of the free end of the pusher can also, if necessary, be first cut before grinding and / or milling.
    With regard to the device, the invention is characterized in that a control system is provided with a data memory for storing a predefined or predefined reference position for driving the filling tool. and blocking means for blocking the driving of the packing tool when it reaches the reference position in an adjustment mode of the device which can be adjusted with the control system and in that it is provided for the pusher a stop element that can be positioned in front of the filling tool.
    In this case, the result is the advantages already described in the explanation of the process according to the invention.
    Reference positions for different garnishing brushes, which may be called as needed, may also be stored in the data memory.
    In order to vary the depth of penetration of the fastening means into the brush body by displacement of the dead center before the pusher, for example for test lines, it is appropriate for an input unit to be able to enter change values. for the reference value is associated with the control system. The input of the modification values can preferably take the form of an indication of length, for example in tenths of a millimeter. This entered value is then converted by the control system into a corresponding angular position from which the rotary eccentric of the stroke drive will be moved before the pusher is connected to the stroke drive. In addition to the input unit, there can also be provided a screen or a similar display element with which the entered values can be displayed and controlled.
    The stop element may be, in the simplest case, a brush body to be lined.
    However, the abutment element is preferably a flat part which can be arranged on the brush body to be filled and the thickness of which corresponds to the distance of the lining tool in its forward dead point relative to a brush body. to garnish. During the entire process of adjustment and adjustment, the pusher is guided in the lining tool and abuts against the flat part in the adjustment position, the front end of the pusher aligning in this case on the end. free of the packing tool. Contrary to what happens by using a brush body as an abutment element, it is furthermore prevented that the pusher inadvertently penetrates, during the adjustment, into a tuft hole instead of abutting against the surface of the brush body. and as a result, the adjustment is not made with the desired accuracy.
    In order to replace and adjust the pusher simply and quickly, it is appropriate for the pusher to be connected with its stroke drive by a removable clamping and can slide longitudinally relative to the drive stroke in the release position. A damaged pusher can then, in the unclamping position, be removed simply in the direction of the length of the stroke drive and a new pusher can be introduced correspondingly. The tightening allows a quick, easy and reliable connection of the pusher and the stroke drive.
    A preferred embodiment provides that the stroke drive has a servomotor. In this way, a rallying of the desired reference position and a stopping and holding of the stroke drive in this position are possible. In addition, a very precise and fine modification of the reference position can be carried out so as to be able to make a micrometric change in the end position of the pusher. In addition, it is possible, if necessary, to give up separate parking brakes, since the stroke drive is sufficiently blocked by the single servomotor - at standstill. The servomotor - even thus forms the locking means for the packing tool.
    In this case, it is appropriate for a toothed belt transmission or a gear transmission to be associated with the servomotor of the stroke drive. Expensive and complex planetary gears are therefore not necessary to achieve a desired gear ratio. This also results in an advantage for maintenance work and the like in which the drive is moved manually by means of a steering wheel and, in this case, singularities during the course of the movement, due for example to a A tool that functions poorly or has problems transporting anchors or tufts, is transmitted to the steering wheel and can thus be noticed by the operator, singularities that would otherwise be eliminated by a planetary gear.
    The toothed belt transmission or the gear transmission can usually have a gear ratio in the range of 2: 1 to 6: 1.
    Since the movement of the pusher and the lining tool are coupled with each other, it is appropriate that the pusher travel drive and the lining tool drive have a common motor as an element. drive.
    In order to be able to grind the pusher in the device, in the event of damage, without having to disassemble and reassemble it, as has already been explained in the description of the process according to the invention, it is advantageous for the control system with the data memory for storing a rear reference position is designed for driving the packing tool and a locking means for blocking the driving of the packing tool when it reaches the position of rear reference is provided in a pusher machining mode of the device which can be adjusted with the control means and a machining device for the pusher which can be positioned in front of the packing tool and the free end of the pusher protruding from the free end of the lining tool is provided.
    In this case, the machining device for the pusher may in particular have a grinding device and / or a milling device. With a grinding device, the free end of the pusher can be polished by grinding and with a milling device, a cavity serving as a guide for a loop of wire of circular section as an anchoring element can be practiced in the pusher.
    It is possible that a grinding device and a milling device are positioned one after the other in front of the pusher. A combination tool in which a milling cutter and a grinding disc are suitably arranged on a common drive shaft is also conceivable.
    If the pusher exhibits gross damage or wear that can not be removed with a grinding device or can only be eliminated in a long time, it may be appropriate for the pusher to pusher has a cutting device. The damaged or worn end can then be cut first and grinding and / or milling then occur.
    To keep the pusher stopped during grinding and / or milling and to prevent oscillation of the pusher, it is advantageous that a slide which can be placed between the free end to be machined of the pusher and the packing tool is provided. for the pusher. This slide can surround the pusher for example in the manner of a fork and be inserted in a simple manner transversely to the longitudinal extension direction of the pusher in the corresponding machining region of the device and be removed again after machining the pusher .
    The machining device can be designed in a modular manner to be able to set it up simply on a machine frame of the device and to be able, if necessary, to equip a posteriori corresponding devices.
    The method according to the invention will be explained in more detail below with an embodiment of the device according to the invention on the basis of the drawing.
    In a schematic way,
    Fig. 1 to
    Fig. 5 show a device with a stroke drive in different adjustment positions during adjustment and adjustment of the pusher,
    Fig. 6 shows a pusher with a machining device for grinding the pusher, and
    Fig. 7 shows a pusher with a milling device for milling the pusher.
    In a device, designated in its entirety by 1, for adjusting a pusher 3 forming part of a lining tool 2 of a brush lining machine, the pusher 3 is mounted so as to slide longitudinally in the machine tool. 2 and is removably connected to a stroke drive 5 by means of a clamping device 4. In this case, the stroke drive 5 has a disk 6 driven by a servomotor (not shown) with a connecting rod. tongue 7 disposed eccentrically thereon. The lining tool 2 also has a not shown drive with which it can be moved in the longitudinal direction of the pusher 3.
    The lining tool 2 reaches a forward dead point in which it is disposed in front of a brush body 8 to be lined and remains for a determined time in this dead point, while the running drive 5 continues to move the pusher 3 until it comes out of the filling tool 2 and enters a hole 9 of the brush body 8. In doing so, the pusher causes a tuft of bristles to be inserted and a fastener, for example a small anchor plate (both not shown) and pushes them into the hole 9. The depth of penetration of the fastener which is determined by the dead point before the pusher must in this case be precisely this is observed so that, on the one hand, the tuft of bristles is firmly anchored in the hole 9 and, on the other hand, it is not damaged by the fixing element.
    To adjust and adjust the pusher 3, for example when it must be readjusted or completely replaced due to wear, the lining tool 2 is first brought to its position in the forward dead center according to Figure 1. In this case, the pusher 3 may, as shown in Figure 1, be retained in a position shifted back. However, it is also possible to proceed with this positioning of the lining tool 2 when the clamping device 4 is open or the pusher 3 is completely removed. According to FIG. 2, a flat piece serving as an abutment element 10 for the pusher 3 is then placed between the packing tool 2 and the brush body 8 arranged in front of the packing tool 2. The running drive 5 continues to move (arrow Pf1) until it is in a defined reference position. This reference position is at an angular distance before the position of the stroke drive in which the rod-shaped rod 7 is disposed parallel to the pusher 3 and the pusher 3 thus reaches its dead point before (Figure 5) and can stored in a data memory of a control device not shown to be able to rally automatically. Different reference positions can be defined for different brush bodies.
    According to Figure 3, when the clamping device 4 is open, the pusher 3 is then positioned so as to abut (arrow Pf2) against the stop member 10 with its front end. When the pusher 3 is aligned in this manner, the clamping device 4 is closed. After the stop member 10 has been removed (Fig. 4), the running drive 5 can continue to move (Fig. 5, arrow PF3). The pusher 3 then reaches exactly the desired depth of penetration in its dead point before. This adjustment and adjustment of the pusher 3 can be performed in a very simple and precise manner even by inexperienced operators.
    With the device 1 shown, it is also very easy to change the depth of penetration of the pusher 3, for example for series of tests, to test to which depth of penetration a tuft of bristles is optimally anchored.
    For this purpose, starting from the situation according to FIG. 2 with the race training 5 being in the reference position, the running drive 5 is moved by a modification value. This new position of the race training 5 then substantially represents a new modified reference position in which the pusher 3 is fitted to the abutment element as previously described. At each angle of a rotational movement of the disk 6 of the stroke drive 5 as a modification value directly corresponds a change in the depth of penetration of the pusher 3. The entry of the modification value can, therefore, be carried out as an angular value or preferably as length data, for example as penetration depth diverging by a few tenths of a millimeter. If the running drive 5 is moved in the direction of the arrow Pf1 with respect to the representation according to FIG. 2 to modify the reference position, the penetration depth of the pusher 3 decreases, since the residual travel movement is smaller. Correspondingly, the depth of penetration can be increased when the position of the stroke drive is shifted in the opposite direction to the direction of the arrow Pf3.
    Figure 6 shows the packing tool 2 in a rear reference position in which the damaged pusher 3 can be machined, without removing it from the device, by a machining device 11 shown in a highly schematized manner. After having reached the rear reference position of the packing tool 2, the machining device 11 is positioned relative thereto in front of the free end of the pusher 3 protruding from the packing tool 2. machining 11 according to Figure 6 has a grinding device 13 with which the free end of the pusher 3 can be ground in a straight line, in that the grinding device 13 is approaching the pusher 3 along the arrow Pf4 and is set in rotation along the arrow Pf5. Such a straight ground grinder 3 is suitable for anchoring the tuft of bristles with the small anchor plate 15 in a brush body.
    To avoid that, during machining, the pusher 3 oscillates with the machining device or is involuntarily deviated at its free end protruding from the lining tool 2, there is provided a slide 12 which surrounds the pusher 3 in the manner of a fork during machining and thus maintains it in a defined position.
    The machining device 11 according to FIG. 7 has a milling device 14 with which a cavity 117 can be made as a guide for the mouth of wire of circular section 16 serving as anchoring element in the free end of the pusher 3 .
