    专利说明:

    The invention relates to a machine for making brushes with different motor-driven machining tools, in particular with a drilling device for drilling holes for tufts of bristles in brush bodies, a tufts feed device, an insertion device for inserting the tufts of bristles into the tufts holes as well as for bringing in anchors and securing the tufts of bristles in the tufts holes.
    In such brush-making machines, the individual machining tools are generally actuated by a central main drive shaft, a mechanical coupling, for example with levers, eccentrics or a similar device being associated with each tool. machining to achieve individual tool movement. This requires a considerable mechanical effort. This is why a secondary shaft is often coupled, for simplification purposes, to the main drive shaft, for example by means of a set of conical wheels which, in turn, carries elements of mechanical coupling for one or more machining tools. The mechanical effort is however very high even in this embodiment.
    Double discs with two levers and two rollers are often used as eccentrics, which requires a lot of space. If the tools are further away from the eccentric concerned, these eccentrics in particular need a lot of space and the associated levers are heavy because of their required dimensions and generate considerable inertial forces. With smaller dimensions and a smaller self-weight, there may be increased deformations and vibrations that are often not tolerable.
    Therefore, the problem is to provide a type of brushing machine of the type mentioned at the beginning, which has a simplified mechanical structure, which is compact and allows the reliable and precise operation of the machining tools.
    The solution according to the invention to this problem consists in that at least one servomotor or stepper motor, which is in driving connection with at least one drive mechanism coupled to the machining tool, is associated in each case with individual machining tools or groups of machining tools of the brush making machine and that the servomotors or stepper motors are connected to a central controller.
    Given the possibility of local arrangement of the servomotors or stepper motors with each time a drive mechanism and therefore also lighter, the need for space for the machine for making brushes is overall reduced, which means that also improves the possibilities of use of the machine for making brushes.
    Since actual control and positioning movements are not generated directly by servomotors or stepper motors, but via proven drive mechanisms downstream, servomotors or stepper motors can operate continuously and therefore in a manner not subject to wear. Because of the smaller sizes of the drive mechanisms, there are generally smaller masses to move and the inconveniences due to otherwise occurring vibrations are avoided. This in turn leads to higher rotational speeds and higher production capacity.
    Depending on the type and number of machining tools, a servomotor or stepper motor with its own drive mechanism is associated with each machining tool. However, it is also possible that several machining tools are driven by a drive mechanism and / or that a servomotor or a stepper motor is coupled to several drive mechanisms.
    An embodiment of the brush making machine provides that it has as a central control a main drive shaft which is actuated by a motor and which is connected to a sensor for determining at least the speed of rotation and in that a control link is provided between the sensor and the servomotors or the stepper motors.
    With the main drive shaft actuated by a motor, servomotors or stepper motors, which in turn are coupled to a drive mechanism, can thus be controlled by the control link and the control link. on the other hand, the driving mechanisms of machining tools, which are arranged in particular near the main drive shaft, can, if necessary, be directly actuated by the main drive shaft.
    Machining tools which are further away from the main drive shaft and / or those with a more complex working movement are actuated via servomotors or stepper motors and drive mechanisms associated, the control of servomotors or stepper motors taking place via an electrical control link and mechanical transmission elements, expensive, therefore not necessary. The drive connection in the electromechanical assembly between the main drive shaft and the machining tool may in particular have an encoder which converts the rotational movement (rotational speed, direction of rotation) of the drive shaft. main drive in electrical signals that are transmitted via an electrical control line to servomotors or stepper motors.
    In the case where no main drive shaft is required to operate the individual machining tools or if such a main drive shaft is not available, the central control can also be an electronic control. As a result, the mechanical stress is further reduced as well as the need for space, so that the entire brush-making machine can also be compactly mounted in cramped work environments. Even when an electronic control is used, the proven technique for converting the rotary motion of servomotors or stepper motors by means of drive mechanisms is always used.
    The drive mechanism for a machining tool may include an eccentric drive, a cam drive or rod drive. Virtually all necessary motion sequences can be converted for each tool.
    For example, the configuration according to the invention of a brush-making machine with electromechanical transmission between a control and a machining tool is particularly suitable for insertion tools. The slide of an insertion tool has to move back and forth at a rotational speed of about 90o rpm 15 times per second for a tool stroke of 50 mm or 100 mm for example. This movement must take place in such a way that at the dead point before movement, a stop occurs until the tuft of hair is introduced into the tuft of hair. In the rear dead center, a longer downtime must be observed and, in fact, during the time necessary for the tuft of hair to be brought in, the anchor wire to be brought in and the tongue to be grasped. anchor wire and tuft of hair. This means that in an embodiment where a servomotor or a stepper motor directly actuates the slide of the insertion tool, the servomotor or the associated stepper motor must change continuously between right and left with short or long stopping points. In addition, the speed of the forward movement must match the speed of advancement of the tongue to the extent that the tongue always runs a little faster than the slide. The tongue has the fastening means in front of it and the folded tuft is in front of the fastening means. The tongue must then always push. If the tool slide had to run faster, it causes the tuft of bristles tightened by folding, and the force link between tab, fixing means and tuft of hair disappears. When, later, the tongue becomes faster and exceeds the slide, it may be that the tip of the tongue no longer touches the thin fastening means, and there is then a blockage or the fastening means is not in a hurry at the same time in the brush body.
    There is therefore a comparatively complicated course of movement with at the same time a high working speed. Servomotors or stepper motors directly actuating the insertion tool accomplishing this complicated movement sequence are thus strongly stressed and wear out quickly.
    By interposing a proven drive mechanism between the servomotor or the stepping motor and the various individual moving parts of the insertion tool such as the tool slide, the tongue (pusher), the arcs and the like , the servomotor or stepper motor can be continuously rotated, allowing longer and trouble-free operation.
