    The invention relates to a device for bringing brush bodies of an inlet buffer into position with unsorted brush bodies to a filling machine with a device. for transporting brush bodies from the input buffer into the area of a transfer clamp for transferring the brush bodies of the transport device to a feed device associated with the filling machine, as well as with a position recognition device associated with the transfer clamp for the brush bodies fed to the transport device.
    For transporting brush bodies between an injection molding machine and a downstream packing machine, transport devices in the most diverse embodiments are part of the state of the art. Conveyor belts or revolving conveyor chains on which support devices for the brush bodies are used are often used. These conveyor belts are cyclically conveyed so that with each feed cycle all the brush bodies are transported simultaneously and fed to the packing device.
    The disadvantage in this case is that there must be a direct association of the packing machine and the injection molding machine with respect to the number of brush bodies manufactured or machined. The failure of one of the machines means that the other machines can not be used either.
    For a continuous workflow, it is therefore also already provided a buffer store along the transport device with which one can proceed to a temporal adaptation of the machining by intermediate storage and the delivery of brush body as needed. Even when disturbances occur in a machining machine, work can continue from the buffer magazine. For sampling and delivery of the injection molded parts, corresponding handling devices are provided.
    DE 699 03 777 T2 discloses a device in which brush bodies are fed from an injection molding machine and / or an input buffer via a transport device to a machine. transfer clamp by which the brush bodies are taken on the transport device and are placed in the corrected position on a feed device associated with a downstream machining station. To roughly separate the brush bodies, they are first placed on a conveyor belt from where they fall on the transport device. In this respect, however, it is problematic that a relatively large number of brush bodies may rest in an unfavorable orientation on the transport device so that these brush bodies can not be grasped by the transfer clamp and after having traveled the transport device must be brought again to this one.
    That is why the problem consists in providing a device of the type mentioned at the beginning with which it is possible to bring the brush bodies, in an improved manner in terms of position and orientation, towards the transfer clamp is possible and therefore to reduce the number of brush bodies that can not be picked up by the transfer clamp.
    The solution according to the invention to this problem consists in that between the input buffer and the transport device, there is provided a sorting device for orienting at least to a large extent the brush bodies in the same longitudinal position. . As a result, the brush bodies are brought onto the transport device in the already corrected position so that only a few brush bodies come to rest on the transport device in an orientation which does not allow them to be grasped by the gripper. transfer. The supply of the supply device brush body is thus improved and the number of brush bodies that run the entire transport device and must be returned to it is significantly reduced. Differences of the brush bodies with respect to an orientation in the same longitudinal position are, in this case, tolerable insofar as they do not prejudice the next position recognition and the subsequent transport of the brush bodies.
    A preferred embodiment provides that the sorting device has at least one grooved sheet having grooves oriented in the direction of travel of the conveyor for receiving the brush bodies and preferably being in operative connection with a vibratory drive. The brush bodies fed from the input pad fall on the grooved plate and are oriented in the conveying direction a comparatively short distance by the vibrating motion. In this case, most of the brush bodies turn lengthwise so that they fall into the grooves and thus arrive at the lengthwise arrangement on the conveyor. The grooved plate may, if necessary, be arranged obliquely downwards in the direction of transport so that the subsequent transport of the brush bodies can take place by gravity, thanks to a corresponding oblique position even without a vibrating drive.
    To subsequently separate the brush bodies, it may be appropriate for the sorting device to have a plurality of grooved plates arranged one after the other, the width of the grooves of a downstream grooved sheet being reduced relative to that of the grooved sheet in upstream of it. When one or more brush bodies are placed in a groove of the first grooved plate, they are, after transfer to the transport device, very close to each other or even above each other. Thanks to other grooved plates with the decreasing groove width, placed one behind the other, the brush bodies which are in a groove of the first grooved plate are distributed over several grooves of the grooved plate downstream so that these brush bodies, after transfer to the transport device, are at a distance from each other and can be better grasped by the transfer clamp. If necessary, a third and, if necessary, additional grooved plates may also be provided to optimize the separation of the brush bodies.
    To also obtain brush bodies oriented in the desired lengthwise direction, even in the case of brush bodies which do not rotate sufficiently with the vibrating movement to fall into the grooves, it is advantageous that at least one retaining rod protruding above the upper edges of the grooves at least on the first grooved sheet in the conveying direction. A brush body resting transversely on the upper edges of the grooves strikes during the forward movement of the retaining rod, whereby the brush body is held on one side against this point of contact, thereby turning, falling into one of the grooves and is thus oriented correctly in the direction of the length.
    The grooved plates of the sorting device preferably have a width which is somewhat less than twice the length of the supplied brush bodies.
    In the case where brush bodies still reach the transport device while being on top of each other, it can be provided to separate them, in the area of the transport device, a brush or a similar scraper to retain brush bodies lying one above the other. This scraper is disposed at a distance above the bearing surface of the carrier device for the brush bodies which allows brush bodies directly on the bearing surface to pass below the scraper and brush bodies that are higher up, so on another brush body, are retained. In this case the lower brush body continues its path until it is moved away from the region of the upper brush body and the latter thus falls on the transport device and can also be transported further under the scraper.
    A preferred embodiment provides that the position recognition device has a camera. With a camera, it is possible not only to detect the position of the brush bodies on the transport device but also other properties such as shape, size, direction of rotation and / or color of the brush bodies to proceed. sorting according to the corresponding properties and take with the transfer clamp only the desired brush bodies or to transmit to the transfer clamp information on the rotation if necessary to properly orient the brush bodies before the tool packing.
    In order to be able to subsequently treat a large amount of brush bodies and / or to treat brush bodies of different colors or with a different arrangement of the tuft holes or with other different properties by sorting them, it is appropriate that several packing are provided with supply devices which are respectively associated with them. The brush bodies may, after recognition by the camera of the position recognition device, be grasped by the transfer clamp in question and be transmitted to the supply device concerned.
    An embodiment provides in this case that each feed device multiple packing machines is associated with a separate transfer clamp. In this case, each transfer clip may also optionally be associated with a camera-specific position recognition device.
    A preferred embodiment, however, provides that all the feeders of the packing machines are associated with a common transfer clamp. This transfer clamp is, in this case, dimensioned and arranged in such a way that it reaches all the supply devices and the transport device. Since only one transfer clamp with a single camera and the related controls is required, the device can be realized in a compact and economical manner.
    In this case, it is appropriate that said at least one transfer clip is made as a tripod with three motorized adjustable arms for positioning a gripping element. Thus, fast and accurate movements can be made to transfer the brush bodies of the transport device on the different feed devices.
    It is advantageous that the feeding devices of the packing machines respectively have one or more buffer stores. The brush bodies are transferred from the transport device into a buffer store and pass from there for example onto a conveyor belt leading to the packing machine. If the packing machine fails, the brush bodies can nevertheless be placed in the buffer magazine. On the other hand, the filling machine can be supplied with brush bodies from the buffer store, when the transport device no longer provides brush bodies, for example due to a failure of the molding machine by injection producing the brush bodies. Thus, operation of a machine is always assured in case of failure of another machine.
    Brush bodies which have not been gripped by said at least one transfer clamp, for example because they are too close to each other or because the buffers of the feed devices are full, go as far as at the end of the transport device. There, they can fall into a collection container and be manually returned to the input buffer or the filling region of the sorting device. To automate this transport process, there can be provided a return device for bringing brush bodies not removed from the transport device to the filling area of the sorting device. This return device may preferably have a conveyor belt which is arranged below the transport device so that the brush bodies fall directly from the transport device onto the conveyor belt of the return device and are brought back onto it.
    The device according to the invention will be explained in more detail below on the basis of the drawings. Schematically, FIG. 1 shows a perspective view of a device according to the invention, FIG. 2 shows a top view of the device according to FIG. 1, FIG. 3 and FIG. 4 respectively show an embodiment of a transfer clamp serving for two delivery devices, FIG. 5 shows a detail view of the sorting device for orientation in the same longitudinal direction of the brush bodies, FIG. 6 shows a side view of a transfer clip made as a tripod, and FIG. 7 shows a top view of the transfer clip according to FIG. 6.
    A device for bringing brush bodies into the correct position to a packing machine 12a, generally designated 1, according to FIG. 1 an input buffer 3 for the brush bodies from which the brush bodies arrive in the unsorted position on a portion divider 4 and are transported to a sorting device 5. The sorting device 5 has two grooved plates 6a 6b arranged one behind the other which are in operative connection with a not shown vibration drive. Thanks to the vibrating movement, the brush bodies are on the one hand moved towards a transport device 7 and on the other hand rotated until they fall into the grooves of the first grooved plate 6a. Such brush bodies which are not yet rotated in the longitudinal direction at the end of the first grooved plate 6a and which rest ink on the upper groove edges 9 (FIG. 5) strike a retaining rod 8 by which they are retained. on one side and, in doing so, rotated until they also fall into one of the grooves of the first grooved plate 6a.
    It is possible that two brush bodies are in a groove of the first grooved plate 6a. To separate brush bodies that are thus one above the other, the groove width of the second grooved plate 6b is reduced with respect to the groove width of the first grooved plate 6a, which is visible in particular in the detailed representation of the sorting device 5 according to Figure 5. When the brush bodies fall in the longitudinal direction of the first on the second grooved sheet 6b due to the vibrating movement and the advancement caused by it , the brush bodies which were together in a groove of the first grooved plate 6a are distributed over a plurality of grooves of the second grooved plate 6b, so that these brush bodies are separated and are transferred to the subsequent transport section at distance from each other on the transport device 7 following it (Figure 1).
    The transport device 7 has a conveyor belt which is shown only schematically in FIG. 1 and on which, after having traversed the sorting device 5, the brush bodies come to rest at least to a large extent in the same longitudinal direction. and at a distance from each other. Along the conveyor 7, there are provided two feeders 11a, 11b which are arranged one behind the other in the direction of travel (Pf 1) and which are respectively associated with one of the packing machines 12a, 12b.
    To transfer the brush bodies of the transport device 7 to the feeders 11a, 11b, a transfer clamp 13a, 13b is provided each time. The transfer clamps 13a, 13b are shown in Figure 1 only schematically by a border limiting their working area.
    The brush bodies run on the conveyor belt below a first position recognition device 14a which is associated with the first transfer clamp 13a and which makes it possible to check in which position the brush body is on the conveyor belt for position the transfer clamp 13a accordingly. It also makes it possible to check whether the respective brush body is in a position and an orientation in which it can be grasped by the transfer clip 13a and, if appropriate, whether the brush body corresponds to appropriate criteria such that the shape and / or color. For this purpose, the position recognition device 14a may in particular comprise a camera. A sorted supply of the brush bodies to the different packing machines 12a, 12b can thus take place in order to be able, for example, to simultaneously treat brush bodies of different shape or to sort by color.
    If a brush body is recognized as suitable by the position recognition device 14a, the transfer clip 13a is correspondingly positioned to grip the brush body and transfer it from the transport device 7 to the feed device 11a. from where the brush body is fed to the filling machine 12a.
    The brush bodies that are not gripped by the first transfer clamp 13a continue to run on the transport device 7 and arrive below a second position recognition device 14b for a second transfer clamp 13b where the position and the properties of the brush body are again detected and the respective brush body is fed with the transfer clamp 13b to another feeding device 11b for a second filling machine 12b.
    Further correction of the position of the brush bodies can also be carried out, if necessary, with the transfer clamps, for example a rotation of the brush body by 180 °, so that all the brush heads to be filled with the different brush bodies are arranged on the same side and / or rotated about the longitudinal axis for the uniform orientation of the packing area.
    As can be seen from FIGS. 1 and 2, the brush bodies are respectively placed in a buffer magazine 10 associated with the feed devices 11a, 11b which, as soon as it is completely filled, is fed to the filling machine. 12a, 12b associated (arrow Pf2). As a result, the filling machines and the inlet buffer 3 or the injection molding device 2 serving therein (FIG. 2) are decoupled from one another so that in the event of failure of one of the devices 2, 12a, 12b, the other can continue to work.
    Brush bodies which have not been removed from the transport device 7 by any of the transfer clamps 13a, 13b, for example because they were too close to each other or to each other, because too much many brush bodies have been brought in or because the buffer stores 10 of the feeders 11a, 11b are full, fall at the end of the conveyor 7 on a conveyor belt 16 of a return device 15 underneath of it (Figures 1, 2, 6). This conveyor belt 16 moves along the arrow Pf3 in the opposite direction to the forward movement Pf1 of the transport device 7, so that the brush bodies are transported back and are again brought to the sorting device 5 by the intermediate of a lifting strip 17 which follows and which opens into the region of filling of the portion divider 4.
    Figures 6 and 7 show an embodiment of a transfer clamp as a tripod with three articulated arms 18 respectively in two parts which can be respectively driven by a motor 19 and which are connected in an articulated manner to each other. other at their ends facing the conveying device 7. At this end of the connecting side of the articulated arms 18, there is provided a gripping member 20 (Figure 6) with which a brush body 21 can be grasped, lifted and transferred onto the feeding device 11 (FIG. 7).
    In FIG. 6, it is also possible to see the return device 15 which runs under the transport device 7 and brings back the brush bodies 21a which have not been grasped by the transfer clip 13.
    Figures 3 and 4 show alternative embodiments for the transfer of the brush bodies of the transport device 7 to the feeding devices 11a, 11b of the packing machines. In this case, only one transfer clamp 13 is provided. This transfer clamp 13 has, according to FIG. 3, a working zone whose dimensions are such that it can serve both fed 11a, 11b.
    In the embodiment according to FIG. 4, there is also only one transfer clamp 13 which does not directly serve the feeders 11a, 11b, but deposits the brush bodies in buffer stores 10a. available separately. The buffer stores are transmitted, after filling, by means of transfer devices indicated by the arrows Pf4, to the feeders 11a, 11b. Thus, a transfer clip 13 having a reduced work area is sufficient.
    The two embodiments according to Figure 3 and 4 have in common that a single position recognition device 14 is necessary here too, which is why all the device 1 can be realized at an advantageous cost.
    The device 1 is not, as shown in the figures, limited to two feeding devices and packing machines. If necessary, three or more filling machines can be supplied with brush bodies.
    The transfer clamp can also be configured as a multiple clamp to simultaneously capture and transfer several brush bodies.
