    专利说明:

    The invention relates to a manually operated device for collecting Fallobst with a driven, radially projecting bending elastic receiving elements having receiving roller for Fallobstaufnahme and a collecting receptacle, wherein between the receiving roller and the receptacle receiving a guide for the recorded from the receiving elements Fallobst is provided.
    DE 102005000874 A1 shows a hand-operated device for collecting fallen fruit which comprises a pickup roller driven by a guide wheel with radially elastic bending receiving elements in the form of bristles, a collecting container and a plurality of guide rails for a guide device and arranged between the pickup roller and the collecting container having recorded by the receiving elements Fallobst. The disadvantage of this, however, that already detected by the receiving elements Fallobst is damaged because this either rolls back the guide before it enters the collection because it is impaled by the jointly driven with the guide wheel bristles, or because it is between these bristles and the guide rails is trapped. Above all, damage to the fallen fruit occurs when the device is moved backwards when maneuvering, because in this case, the pickup roller changes its direction of rotation and already expelled fallen fruit again expels.
    The invention is therefore based on the object, a hand-operated device for collecting Fallobst in such a way that damage to the fall can be avoided regardless of the direction of travel.
    The invention achieves the stated object by virtue of the fact that the guide device has a convex pretensioning region and a concave expansion region for the receiving elements adjoining it in the direction of the collecting container holder.
    According to these measures, the guide, which may be formed, for example, as a grid, an S-shaped profile, wherein the transition region between bias and relaxation area represents the turning point. In the course of the rotation of the pickup roller, the pickup elements come with their end sections coming from ground level onto the end section of the convex preload area. As a result, the projecting end portions of the receiving elements are stopped in their tangential movement, while the fall of them and conveyed to the convex biasing region of the guide is prevented from rolling back by the receiving elements. Since the roll lug of the receiving elements continues to move in accordance with the rotational movement of the take-up roll while its end portions are initially stopped by the guide, a stress may build up in the take-up elements due to its bending elasticity. Subsequently, a correspondingly biased receiving element moves the detected Fallobst along the Vorspannungsbereiches before him until it emits the previously stored restoring force to the Fallobst momentarily as an impulse in the transition region of the guide according to the change in curvature of the S-profile. As a result, the fruit experiences a higher speed of movement than would have been possible only by the rotation of the pickup roller. In this case, this speed is sufficient to transport the fall over the transition area along the relaxation area of the guide into the collecting receptacle or a collection container or a box provided there. Due to the steady decrease in the slope of the relaxation area due to its concave configuration, the fallen fruit is braked again on the way into the collecting container so that it gets in as gently as possible there. To ensure that the fallen fruit also gets into the collecting container or box provided for this purpose and does not fall off the guide laterally, a protective grid can be provided on the two lateral sides of the guide and the collecting container receptacle.
    Although it is not important that the receiving elements are formed, for example, omega-shaped or in loop form, particularly advantageous conditions arise when the bending elastic in the tangential direction of the pickup roller receiving elements form a roll neck and an end portion, the end portion has a higher bending elasticity than having the roll approach. Due to these features, deflection does not occur uniformly over the entire length of a female member, but extends primarily over its more flexurally elastic end portion. Thereby, the end of the receiving element is displaced due to a deflection to a lesser extent along the tangential trajectory, so that sufficient space is provided between the receiving elements in the circumferential direction and a circumferentially subsequent receiving element is not limited in its recording process of the fallen fruit. The different bending elasticity of the end portion and roll neck of a receiving element according to the invention is not to be understood solely as meaning that due to a corresponding material composition there is a gradual decrease in the bending elasticity from the end portion to the roll neck. The local weakening of the end section, as a result of which it subsequently becomes more flexurally elastic, can be achieved by recesses provided there. These recesses allow, according to a mass reduction of the end portion, that the pulse provided according to the deflection of the end portions fails only as high as necessary in order to convey the fallen fruit as gently as possible along the guide into the collecting container. Furthermore, it can be avoided by the recesses, in particular if they are formed hole-shaped, that on the Fallobstwiesen or Fallobst existing impurities are carried unnecessarily.
    When axially arranged in a row receiving elements, the problem arises of selectively occurring high force peaks during a pick-up cycle, since the entire series of recording elements is biased simultaneously and the pickup roller must provide a disproportionately high torque at those times. If the restoring force stored in the receiving elements is then abruptly transferred to the detected fall, the forces released by it may cause collisions of the fall or may transport it into the collecting container at too high a speed, thereby damaging it. Therefore, it can be provided according to the invention that the receiving elements are arranged in the tangential direction in the gap offset axially extending rows on the receiving axis. As a result of these measures fewer pieces of fallen fruit are detected during a pick-up cycle, so that the moment load on the pick-up roller may be lower due to the folded pieces or the pre-tensioning area, resulting in an overall higher operational stability of the device. In addition, the staggered in the tangential direction gap arrangement of the receiving elements that the moment load fails more consistently and has no periodically occurring force peaks, as at any time a constant number of Fallobststücken and preloaded receiving elements induces the moment load, which ultimately results in a smoother running of the pickup roller and as a whole, the risk of damage of the fallen fruit can be reduced. Moreover, it has proved to be particularly advantageous for the receiving operation of the fallen fruit when a lateral guide for the fallen fruit to be collected is formed by the two adjacent receiving elements of a receiving element. As a result, a detected Fallobststück is prevented not only by the pulse-transmitting receiving element from rolling back, but also laterally supported by the two adjacent, offset in the tangential direction of rotation receiving elements. Subsequently, the detected Fallobststück can be safely transported to the guide, wherein the guide also ensures that the accelerated by the impulse transmitted from the receiving element Fallobst passes on a straight path along the guide into the sump.
    In order to allow a damage-free picking up even with uneven floors and to avoid damage even when the device during
    Ranging is moved backwards, it is proposed that the guide for adjusting the bias of the receiving elements on the side of the relaxation area hinged to a frame and is supported on the side of the biasing range via adjustable length spacers on this frame. Thereby, the guide is rotatably mounted around the relaxation area, wherein the axis of rotation parallel to the longitudinal direction of the pickup roller extending axis may be arranged in a range from the turning point of the guide to the end portion of the concave relaxation area. Because of these features, the guide is adjustable in height relative to the ground level, which give way depending on the bump the guide and thus can adapt to the particular terrain. The end portion of the preload region is therefore always in a favorable position for the Fallobstaufaufnahme near the bottom. If the device is also moved backwards during maneuvering, it is possible, due to the height-yielding guide, to prevent damage to the tattle pieces located underneath the device, since they can not be pinched and crushed between the guide device and the floor. In addition, a separate restoring device can be dispensed with, since the receiving process, the receiving elements open anyway on the convex bias voltage range and press the spacers back against the frame. By adjustable in length and supported on the frame spacers also the bias of the receiving elements can be adjusted so that the transmitted through the receiving elements impulse can be matched to the size of the collected fall fruit.
    In order to allow a collection of the fall even with uneven floors and the case required different maneuvering movements of the device so that it is not damaged, the pickup roller can have an independent, controllable in the speed drive. Thus, the pulse to be transmitted to the Fallobst can be adjusted over the speed of the drive roller to thereby avoid damage to the Fallobststücke by high pulse bursts. Since regardless of the maneuvering direction, the direction of rotation of the pickup roller can be maintained, a damage-free collection of Fallobst is also effected in a backward movement together with the flexibly mounted guide. In addition, it is possible to use a commercially available cordless screwdriver as a drive device, since the design-related lower moment load of the pickup roller a lower power requirement, which can be covered by such a cordless screwdriver already.
    In the drawing, the subject invention is shown, for example. Show it
    Fig. 1 is a side view of a hand-operated device according to the invention for collecting Fallobst and
    Fig. 2 is a plan view of Fig. 1 on a larger scale.
    The hand-operated device according to the invention for collecting Fallobst has a pick-up roller 1 with radially projecting flexurally elastic receiving elements 2, which is fastened to a frame 3. In order to facilitate the transport of the device, the frame 3 can be designed to be foldable. The device can also have telescoping grip parts 4 connected to the frame 3 in order to be able to adapt the device to the size of the user and to be able to carry out manually operated maneuvering movements. To enable the device to move, the device has wheels 5. Thus, the captured by the receiving elements 2 Fallobststücke arrive without damage in a provided in the receptacle receptacle 6 box, is located between the pickup roller 1 and the receptacle 6, an S-shaped guide 7, which has a convex preload area 8 and in the direction of the receptacle receptacle 6 thereto Has concave relaxation area 9 for the receiving elements 2. In this case, during a picking cycle, the end portion of a receiving element 2 is bent back and biased by the end portion of the convex biasing portion 8, along the guide 7 to its turning point and 10 moves the previously stored restoring force as a pulse to the moving Fallobststück from, so this along the concave Relaxation area 9 passes into the box provided the collection receptacle 6. In order to avoid lateral fall of the fallen fruit, a protective grid 11 may be provided on the two lateral sides of the guide 7 and the collecting container receptacle 6.
    The receiving elements 2 can be arranged in axially extending rows, which are offset in the tangential direction to gap on the receiving roller 1, wherein the two adjacent receiving elements 2 of a receiving element 2 can form a lateral guide for the fallen fruit to be collected.
    The guide 7 can be hinged to adjust the bias of the receiving elements 2 on the side of the relaxation area 9 on a frame 3 and be supported on the side of the biasing region 8 via adjustable in length spacers 12 on this frame 3.
    In an area provided for this purpose, an independent and controllable in the speed drive for the pickup roller 1 may be arranged, wherein the torque transmission of the drive shaft 14 may be carried to the pickup roller 1 via a belt drive 15.
