    Description Technical Field The invention relates to a feeder for the ordered feeding of parts via a vibrating mechanism.
    Background Art Feeders are known that can move parts from a container to a feed position via a vibratable feed rail. In order to prevent several parts from arriving at the feed position at the same time or no part being there at all for a certain time, CN 103 449 171 proposes to provide suction mechanisms at a plurality of stowage chamber positions so as to hold a part at certain desired intervals. When a part is removed from the supply rail, all parts travel ahead of a stowage chamber position. The intake mechanism at the take-off point can be inverted to improve the reception of the part from the take-off point. However, even with this solution for small parts it is possible that at certain stowage chamber positions, two parts or no part arrives, so that it can interfere with the feeding mechanism.
    Other feeding mechanisms as in JP 2006 298 578 or in WO 12 078 112 use, instead of a vibrating mechanism, air openings in the guide rail for suction at stowing chamber positions or for moving the parts. But even here, for small parts at certain stowage chamber positions, two parts or no part can arrive.
    DISCLOSURE OF THE INVENTION It is an object of the invention to find a feeding device which reliably supplies (at) only a part at the feeding position when a part has been removed from the supplying position.
    According to the invention, this object is achieved in a feeding device according to claim 1.
    By combining the stop mechanism with the part detector at the stowage chamber positions, the feeder can accurately monitor and control the delivery of parts to the guide rail. Should a stowage chamber position remain vacant, the parts of the previous stowage chamber position can all move up one position. Thus, the one-time occupancy of each stowage chamber position can be ensured, and thus a quick tracking of a part to the feeding position can be secured when taken out of the feeding position. This monitoring capability of the stowage chamber positions thus improves the reliability of the delivery of the parts.
    Further advantageous embodiments are specified in the dependent claims.
    Brief Description of the Drawings The invention will be further described with reference to the accompanying drawings in which:
    Fig. 1 is a three-dimensional view of an embodiment of a feeding device;
    Fig. 2 is a side view of the feeder of Fig. 1;
    Fig. 3 is a plan view of the feeder of Fig. 1;
    Figure 4 is the section A-A through a guide rail of the feeder of Fig. 3. and FIG. 5 the section B-B through a guide rail of the feed device from FIG. 3.
    Modes for Carrying out the Invention Figs. 1 to 5 show a possible embodiment of a feeding device. The feeder serves to supply parts, for example, to a production machine which assembles a product of different parts. The parts are usually mechanical parts, and the feeder can also use electrical parts. The parts are usually smaller than 5 cm, in particular smaller than 1 cm. It could, for example, be parts of a movement.
    The feeder comprises a container 1, a guide rail 2, a Behälterrüttelmechanismus 3, a Längsrüttelmechanismus 4 and a control device.
    The container 1 is adapted to receive a plurality of parts to be supplied and to convey these to the upper edge of the container 1. In the illustrated embodiment, the container 1 is formed with a uniformly rising container wall (e.g., at an angle between 30 ° and 60 °). The rising container wall has, on the inside of the container 1, a step 11 which winds up helically along the container wall up to the upper edge of the container 1. This gradation 11 is designed to transport parts of the loading container bottom to the upper edge of the container. The helical step 11 terminates preferably where the guide rail 2 is to take over the parts from the container 1.
    The container 1 is mounted on a container shaking mechanism 3 which is adapted to vibrate the container 1 so that the parts migrate from the container bottom to the upper container rim, e.g. Preferably, the container shaker mechanism 3 generates circular vibrations which allow the parts to travel up the helical step. This can be achieved for example by a rotary vibrator. This can be achieved by a motor or by a piezo mechanism or by other means. The container mechanism 3 and the container 1 are preferably mounted on a common mounting plate 5.
    The guide rail 2 extends from the upper edge of the container 1 to a feed position and is adapted to convey the parts from the container 1 to the guide rail 2 to be transported to the feed position. Preferably, the guide rail has a recess 26 which extends along the longitudinal axis of the guide rail and serves to position the parts. In this embodiment, the recess has a triangular cross-section (see Fig. 5). Preferably, the guide rail 2 forms a plane along the longitudinal axis. The recess 26 is preferably arranged in the plane.
    The guide rail 2 is mounted on the longitudinal vibrating mechanism 4. The longitudinal jogging mechanism 4 is configured to shake the guide rail 2 so that the parts located on the guide rail 2 and in the recess 26, respectively, are moved from the container 1 along the longitudinal axis of the guide rail 2 to the feeding position. The longitudinal vibrating mechanism 4 preferably generates vibrations of the guide rail 2 in the direction of the longitudinal axis of the guide rail 2. This can be generated for example by a motor or a piezo mechanism. Preferably, the Längsrüttelmechanismus 4 and the guide rail 2 are mounted on the common mounting plate 5.
    According to the invention, the guide rail 2 now has a plurality of stowage chamber positions 21 for selectively supporting a part in each case along the feed rail 2. Each stowage chamber position 21 has a parts detector 23 and a stop mechanism.
    The part detector 23 of a stowage chamber position 21 is configured to detect whether a part is in the stowage chamber position 21 and / or if no part is in the stowage chamber position 21. As part of detector 23, a light barrier is preferably used. If the light barrier is interrupted, a part is at the appropriate stowage chamber position, otherwise it is empty. Preferably, the light barrier 23 is arranged so that the light beam of the light barrier extends through the recess 26. For this purpose, preferably recesses 28 are provided in the guide rail 2, which extend at right angles to the longitudinal axis of the guide rail 2 and guide the light beam of the light barrier 23 through the recess 26 (see Fig. 5). Preferably, the light beam of the light barrier 23 is arranged horizontally when the feeding device is set up in an operating state. Preferably, the light barrier is arranged so that the light beam of the light barrier 23 is arranged in a plane parallel to the plane of the guide rail 2 (also identical). Preferably, the light barrier is arranged in the guide rail 2, so that the light beam of the light barrier 23 extends in the guide rail. The described arrangement of the light barrier has the advantage that the detectors do not cover the guide rail 2 and that a user's hand over the guide rail 2 does not lead to an interruption of the light barrier. However, other part detectors 23, such as cameras, induction detectors, etc., may also be used.
    The stop mechanism of a jam chamber position 21 is adapted to hold a part against the force of the jogging mechanism 4 in the jam chamber position 21. Preferably, the stop mechanism has a suction mechanism. This can be formed by small openings in the guide rail 2 and in the recess 26 at the storage chamber position 21. Air is sucked through the opening, so that a part located in the stowage chamber position 21 is sucked to the opening. Preferably, each jam chamber position 21 has its own suction mechanism (e.g., pump) connected to the port. The suction mechanism is connected to a respective conduit 27 with the corresponding opening. Alternatively, it is also possible to connect the openings of the various stowage chamber positions 21 via lines with a common intake mechanism. The opening is preferably formed as an elongated slot extending along the longitudinal axis of the guide rail 2. This elongate slot is preferably located at the lowest point of the recess 26 or at the edge of the triangular recess 26 (and at the stowage chamber position 21). Furthermore, it is advantageous if the stop mechanisms are individually, i. can be controlled independently of the other stop mechanisms. The realization of the stop mechanism as suction has the further advantage that no structures on the guide rail 2 are necessary and this is easily accessible. This is particularly advantageous in combination with the arrangement of the light barriers 23 described above.
    Optionally, the guide rail 2 may still have a control position 22. The control position 22 is preferably arranged between the container 1 and the first storage chamber position 21. Alternatively, the control position 22 but also the first storage chamber position 21 correspond. The control position 22 comprises a control mechanism for controlling the correct positioning of the supplied part and a return mechanism 25 for returning an incorrectly positioned part into the container 1. The control mechanism preferably comprises a parts detector 24 and a camera (not shown). Once the parts detector 24 the presence of a supplied part in the

    Control position 22 detected, is taken with the camera an image of the position of the part. On the basis of the image, it is then decided whether the part is positioned correctly or incorrectly. The camera is preferably arranged below the guide rail 2 or the recess 26, which is designed to be transparent in the area of the control position 22 in order to detect the correct position with the camera through the guide rail 2 or the recess 26. The guide rail 2 or the recess 26 may be made of glass in this area, for example. The parts detector 24 may be formed like the parts detector 23 of a storage chamber position 21. If the check position corresponds to the first jam position 21, the parts detector 23 could also be used as the part detector 24. The return mechanism 25 is preferably a blower that blows the part back into the container 1. The guide rail 2 has at least one feed position. This could be, for example, at the end of the guide rail 2 opposite the container 1, e.g. when the feeding takes place through out of the guide rail 2. The feed position could also be a well-defined position on the guide rail 2 at which another machine is to pick up the part. This recording can be done for example by a tap, a suction, etc. This delivery position could, for example, represent one of the stowage chamber positions 23, e.g. those last passed from the part. It is also necessary for certain acceptance machines to simultaneously remove several parts at the same time. This could be realized by using multiple stowage chamber positions as feed positions. Preferably, however, a number of stowage chamber positions 21 are not used as feed positions, so that the feed position (s) can be replenished quickly and reliably after removal of the part. This can be realized, for example, by switching off the stop mechanisms of the stowage chamber positions 21, so that the parts stored therein continue to travel around a stowage chamber position 21 and the feed position is refilled. The control device, not shown, is connected to the part detectors 23 and the stop mechanisms. The controller obtains the detection result from each of the part detectors 23, so that the control device knows which stowage chamber positions 21 are occupied and which are not. The controller may drive the stop mechanisms (preferably individually), i. turn on and off. The control device controls the stop mechanisms in response to the obtained detection results of the part detectors 23. This is preferably done so that all stowage chamber positions 21 are occupied by a part. When a part is to be taken from the feed position or after this part has been taken from a filled feed position, the stop mechanism of the stowage chamber positions 21 is turned off so that the parts of the filled stowage chamber positions 21 can wander one position. Even if the control device detects that one of the stowage chamber positions is no longer occupied (for example because a part has fallen or has been removed from the supply rail), the control device can switch off the stoppage chamber stoppage stop mechanisms 21 before the empty stowage chamber position and thus the empty stowage chamber position 21 fill up while the stop mechanisms of the subsequent stowage chamber positions 21 are not turned off to continue to hold the parts therein. It is also possible to use the suction mechanisms of the filled stowage chamber positions 21 (not only off, but also) as blowing mechanisms, so as to move the parts more quickly out of the stowing chamber position 21 as the parts of the filled stowage chamber positions 21 continue to move one position should. In the embodiment shown, this is achieved in that the longitudinal axis of the channel 27 at the opening has a component in the direction of the longitudinal axis of the guide rail 2 in the direction of movement of the parts (see Fig. 4). Thus, by simply (and temporarily) switching the suction mechanism into a blowing mechanism, e.g. by changing the direction of rotation of the pump, the parts are moved faster out of the stowage chamber position 21. The control device may also drive other mechanisms of the feeder such as the Behälterrüttelmechanismus 3, the Längsrüttelmechanismus 4, the return mechanism 25 or the control trollmechanismus. claims
