    Low-knuckle gripper
    The invention relates to a picking system for automated picking of articles with a detection station for detecting the position of an article to be picked on a supply conveyor unit and with a articulated arm gripper for picking up the article from a storage loading aid from the supply conveyor unit and for placing the article in an order loading aid on a conveyor unit, wherein the articulated arm gripper is positionable by a kinematic unit of the order-picking system within a working range of the kinematic unit and wherein the articulated-arm gripper has a substantially vertical longitudinal arm and a kinked arm which can be bent by a kink angle and on which a gripping device for gripping the article is provided.
    The document EP 1 160 166 B1 discloses a sorting system in which articles in the form of food slices on a first conveyor belt are fed to two robots with which the food slices are sorted into a package on a second conveyor belt. The robots have a kinematics unit, which is formed by a so-called delta kinematics with three delta arms. On the kinematic unit, a gripper is mounted, with each of which a food slice is picked up with a suction gripper from the first conveyor belt and stored on an inclined surface in a package on the second conveyor belt. For this purpose, the gripper has a fixed to a longitudinal arm to a certain, once set angle bent arm.
    An optical detection station has a detection cone. which is directed to the first conveyor belt and detects the position of the food slices on the conveyor belt. This position information is transmitted to a control device of the sorting system, which controls the two robots. To pick up a food slice, the kinematic positions the gripper immediately above the food slice on the first conveyor and the suction pad sucks the food slice. For depositing the food slice, the controller positions the gripper with the picked food slice above a free position of the package. In this case, during the positioning of the gripper from the first conveyor belt to the second conveyor belt, an angle of rotation of the gripper about the longitudinal arm of the articulated arm gripper is always equal to a first angle of rotation during picking up the food disc adjusted to an always same second rotation angle for dispensing the food slice. The suction gripper then delivers the food slice into the packaging. The articulation angle of the arm was once set in the structure of the picking system to the position of the feed conveyor unit and the discharge unit.
    In the known sorting system has proven to be a disadvantage that with the gripper only articles can be taken from the flat first conveyor belt and stored in the flat package on the second conveyor belt. The supply of food slices on the first conveyor belt does not take place from storage loading aids but these are occasionally fed to the robots. The situation is different for articles to be picked from a picking warehouse, which are usually stored in certain warehouse loading equipment. This results in the Kinematikeinheil and in particular for the articulated arm gripper other requirements that are not met by the known gripper.
    The invention has for its object to provide an automated picking system with a Knickarmgreifer, are avoided in the above-mentioned disadvantages. According to the invention, this object is achieved in that the articulated arm gripper is designed for holding the article to be picked from bearing storage aids transported on the supply conveyor, the longitudinal arm of the articulated arm gripper being at least twice as long and in particular at least five times as long as the articulated arm of the articulated arm gripper and in that the detection station is adapted to detect the three-dimensional position of the article in the storage loader and that the articulation angle of the articulated arm and a rotation angle of the articulated arm gripper about the longitudinal arm are freely adjustable depending on the detected position for gripping the article.
    As a result, the advantage is obtained that the articulated arm can also grip items from a storage loading aid, which are optionally positioned strongly inclined or difficult to access. Articles in a storage load support are greatly inclined, in particular when a flat article surface is inclined to the horizontal and optionally collides with the loading equipment wall. Articles are difficult to access in a storage loader especially if they are in one of the Fxken of the
    • · · «·» ··· · · · * · · · · · · · «♦♦ ··«
    Storage loader lie or, if they are partially hidden under other items in the form of bulk material from possibly different items.
    Due to the three-dimensional detection of the position of the article to be picked in the storage loader and the free adjustability of the bending angle and the angle of rotation of the articulated arm in combination with the relatively long Längsann and short articulated arm of Knickarmgreifer can be precisely adjusted and positioned so that even in Lagerladehilfsmittel difficult to reach To be picked articles with maximum gripping force and precision.
    If the gripping device is designed as a suction gripper, then it has proven to be advantageous to suck the article with the suction pad and support against at least two and particularly advantageous against at least three supports. This prevents the article from oscillating during order picking when accelerating the kinematic unit or even from the suction gripper. It is particularly advantageous to adjust the support points depending on the article size or article weight in order to obtain the largest possible contact surface within the support points. For this purpose, the distance of the support points of the suction pad can be adjusted electromechanically, or it can be the entire gripper, replaced in a Greifkrwcchselstation described below, against a gripper with other support points.
    Furthermore, it has proved to be advantageous to provide the articulated arm of the articulated arm gripper immediately after gripping the article either by gravity or for example by means of a return spring vertically, ie in the direction of the longitudinal arm. This allows the gripping device fix the recorded article much safer.
    Depending on the spatial position which the article to be picked occupies in the storage load aid, and depending on which position of the storage load aid the article is to be received with the articulated arm gripper, different approach strategies or driving journeys of the kinematics unit for positioning the articulated arm gripper are advantageous. If the article to be picked is difficult to access or difficult to grasp, because the articulated arm gripper has only relatively little space for gripping the article, then it has proven to be advantageous for the articulated arm gripper with the articulated arm positioned vertically downwards to move from the kinematic unit to the position is positioned to receive the article, and that the kick arm is only then inserted into the opening position of the kicking arm.

    Control device predetermined, bending angle is adjusted. On the other hand, an easily accessible in the male Lagerladehilfsmiltel article can be taken up faster when the articulated arm of the articulated arm gripper is already set during the positioning by the kinematic unit to the predetermined kink angle and angle of rotation.
    Furthermore, it has proved to be advantageous if articles to be picked for an order are initially deposited on one intermediate buffer platform by one or more storage loading aids which are delivered on the supply conveyor and are poured together into the second order loading device associated with the order. It is particularly advantageous in this case with respect to shock sensitive, to be picked items to picking or because of their size or weight as the first or last to be placed in the order loading aid articles from the articulated arm directly into the order loader. The other items (first group) poured from the intermediate buffer platform into the order loader may be poured before or after the item (second group) directly picked into the order loader.
    In order to adapt the picking system for automated picking to different types of stock and order loading equipment (e.g., different materials, dimensions, pitches within the load supports), it is advantageous to provide a picker change station. The control device can thus depending on the nature of the storage loader or depending on the type of contract lad ehilfsmittels by means of the kinematic unit, parked on the kinematic unit, Knickarmgreifer station in the gripper exchange station and a mechanism ansteuem attached another suitable articulated arm gripper from the gripper changing station to the kinematic unit , It could also be carried out only a change of already attached to the kinematic unit Knickarmgrcifem. For example, the control device could adapt the articulated arm gripper by means of a turret device depending on the type of storage loading aid and the order loading aid as a function of the ratio of the article dimension to the loading aid dimension.

The detection station 2 is formed by a combination of sensors together with associated object recognition software, which is processed by a control computer, not shown in FIG. Such a detection station 2 is already known from the prior art, which is why will not be discussed in detail. It should be noted, however, that the detection station 2 detects not only the position of the article P (its coordinates) but also its spatial orientation, that is, its position (e.g., angle of its surfaces in a spatial coordinate system). 6 • * * · • * * ·
    In one, not shown in the figure I, warehouse picking system 1, the articles to be picked are stored in warehouse loaders LLH various dimensions, shapes and weights. Depending on the type of article or type of bearing, warehouse load supports LLII may have different ratios of base area to side wall number and height. The control computer compiles corresponding incoming sales orders, picking orders. According to the order control, a conveyer system conveys the stock loading aids LLH of the articles P to be picked from the automated warehouse and transports them to a feed conveyor Z constituted by a conventional conveyor belt. The feed conveyor Z first conveys the storage load supports LLH through the detection station 2 and then to a kinematic unit K, which receives the corresponding number of articles P to be picked from the storage load support LLH and deposits them in the order load support ALH on a discharge conveyor A.
    FIG. 2 shows in more detail the kinematics unit K, the feed conveyor Z with storage loading aid LLH and the discharge conveyor A with order load aids ALII in the working space R. The kinematic unit K is formed by a delta kinematics with three double arms 7 and a rotary arm DA and is controlled by the control computer to position an articulated arm gripper 6 fixed to the kinematic unit K within the working range of the kinematic unit K and to turn the articulated arm gripper 6 about its own axis , Such a kinematic unit K is known for example from the document W02005 / 051812 Al. According to another exemplary embodiment of the invention, it would also be possible to realize the kinematic unit K by any type of industrial robot to which the articulated arm gripper 6 would be attached.
    In the figure 3 right, the function of the articulated arm gripper 6 is shown as a symbol image. The articulated arm gripper 6 has a longitudinal arm 8, which is substantially vertical in the operating position, and an articulated arm 9 which can be bent by a bending angle W. With the rotary arm DA of the kinematic unit K, the articulated arm gripper 6 can be turned continuously about the axis of the longitudinal arm 8 into a rotational angle DW predetermined by the control computer. The articulated arm gripper 6 has, as a gripping device for gripping articles P, a suction gripper S with a suction bellows SB. A, not shown in the figures, pneumatic device sucks, controlled by the control computer, the article to be picked for picking up the article P by means of suppression in
    * I 7: •. »*« • t *
    Suction bellows SB on. To release the article P, the suppression is compensated, whereupon the sucked article is released from the suction bellows SB.
    In the figure 3 right an article P is further shown, which is positioned obliquely on the container wall BW of Lagerladehilfsmittles LLH. Due to the ratio of small container base to high container wall height, the articulated arm gripper 6 has a longitudinal arm 8, whose length LI is three times longer than the length L2 of the articulated arm 9. As a result, it is advantageously achieved that articles P can also be picked up from small storage loading aids LLH with the kinematic unit K and can be picked into the order loading aids ALH. It is particularly advantageous in this case that the detection station 2 detects not only the position of the article P in the storage loading aid LLH but its three-dimensional position. As a result, the bending angle W and the rotation angle DW can be set by the control computer such that the articulated arm 9 is perpendicular to the surface of the article P at which the suction gripper S attaches. For this reason, despite a small suction bladder SB, the article P having maximum suction force can be surely picked up and held from the storage loader LLH.
    Depending on the type of load equipment, the longitudinal arm may also be formed five or twenty times as long as the articulated arm in order to reliably reach all gripping points in the warehouse loading aid LLH and to reliably pick up the item P even in inaccessible positions of the article P to be picked. In the figure 3 left a storage loading aid LLH is shown with a high container wall BW, from the corner of the articulated arm gripper 6 receives a last item P. On the basis of this FIG. 3 on the left, it can be seen with what small space requirement the articulated arm gripper 6 can take articles P from the storage loading aids LLH. To illustrate this even better, a conventional gripper 20 according to the prior art is shown in Figure 11. With reference to this Figure 11, the problem with such a gripper 20, the product P on its surface 21 in a narrow storage loader LLH to grasp immediately apparent.
    In FIG. 4, on the left, a storage loading aid LLH is shown, in which articles P to be picked are sorted next to one another. In Figure 4 right another situation is shown, are arranged to be picked in the article P as bulk material. In practice, there are also mixed forms of sorted articles P and
    Schültgutanordnungen. FIG. 5 shows a pure bulk material situation of articles P whose spatial position is detected by the detection station 2, so that the articulated arm gripper 6 can grasp one or more of these articles P safely and pick them into one of the order loading containers LLH.
    Four further examples of storage load supports LLH are shown in FIG. 10, in which a different number of smaller storage load carrier containers are accommodated in a bottom of the warehouse loader LLH. Articles of different quantities and sizes can be stored efficiently in these different storage loaders LLH. With the articulated arm gripper 6, items from the small storage container for storage containers can be gripped well and safely and picked.
    FIG. 6 shows the articulated arm gripper 6 of the picking system 1 according to FIG. 1 in a side view and a front view. In Figure 7, the articulated arm gripper 6 is shown in an oblique view. The articulated arm gripper 6 has a holding device 10 with which the articulated arm gripper 6 is fastened to the kinematic unit K. This holding device 10 is in this case realized such that a, not shown, mechanics of the kinematic unit K solve the holding device 10 by a control command of the control computer and can fix it again. This is necessary because the kinematic unit K of the picking system! has a, not shown in the figures, gripper changing station with different Knickarmgreifern. Depending on the nature of the storage loader and the article P to be picked on the feed conveyor Z, the kinematic unit K can be moved under control of the control computer to the gripper change station to release the kinked arm gripper 6 attached to the kinematic unit K from the kinematic unit K, and one others, in the gripper change station in stock to attach Knickarmgreifer to the kinematic unit K. The articulated arm gripper 6 in the gripper changing station can have different length ratios of the longitudinal arm 8 to the articulated arm 9, narrower or wider, or also have the necessary stability to carry larger loads. In this way, the advantage is obtained that the kinematic unit K including articulated arm gripper 6 can be automatically adapted to different article sizes and storage loading aids during picking during picking.
    It may be mentioned that the gripper changing station could also be realized in the manner that two or more grippers are attached directly to the kinematic unit K. For example, these could be attached to the kinematic unit K by means of a turret holder, wherein in each case one of these grippers would be rotated to the operating position and controlled by the control computer for gripping articles P.
    In the figures 6 and 7 further two pneumatic cylinders 11.1 and 11.2 are shown parallel to the longitudinal arm 8. About the respective compressed air connections 12 is controlled with the pneumatic cylinders 11.1 and 11.2, controlled by the control computer, the bending angle W of the longitudinal arm 8 to the articulated arm 9. The Kickarm 9 also has four supports 13 which surround the suction bellows SB of the suction pad S immediately. The suction bellows SB is acted upon to receive an article P via a vacuum port 14 with a negative pressure. As a result, the suction bellows SB contracts and the article P is pressed against the four supports 13. In this position, the article P is kept particularly strong and reliable by the suction gripper S and does not start to oscillate even during abrupt acceleration or deceleration by the kinematic unit K.
    In Figure 8 left a square area of the packaging of an article P is shown. After determining the exact position of an article P by the detection unit 2, the control computer determines the easiest to be included with the articulated arm gripper 6 article P in Lagerladehilfsmiltel LLH and on which surface of the article P of the suction gripper S can best apply. Once the surface is fixed, the centroid of that surface is determined and the control computer controls both the kinematic unit K and the articulated arm gripper 6 so that the center M of the support ring AR of the suction bladder SB attaches to the centroid of the selected surface. The bending angle W and the rotation angle DW of the articulated arm gripper 6 about its longitudinal arm 8 are adjusted so that the articulated arm 9 is exactly perpendicular to the selected surface. The Abslützungen 13 are here at support points AP on the surface of the package. The larger the support surface AF defined by the support points AP is on the surface of the article P, the more reliable the article P is held by the suction gripper S. As a result, the article P with maximum gripping force can be received by the articulated arm gripper 6.
    The control computer determines the control of the movement of the articulated arm gripper 6 using a collision avoidance algorithm. When approaching the articulated arm gripper 6 to the article P and when removing the sucked article P with the articulated arm gripper 6, the control computer takes into account the dimensions of the kinked articulated arm gripper 6 and the sucked article P to collide with the container wall BW or the articles remaining in the storage loader LLH P to avoid.
    It is now particularly advantageous that the supports 13 of the articulated arm gripper 6 are made adjustable. The distance of the supports 13 from each other is determined by the control computer when it is determined on which surface of the article P the suction gripper S will receive the article P. In Fig. 8 right an example of a rectangular area of the packaging of an article P is shown. The control computer adjusts the supports 13 on the articulated arm gripper 6 in such a way that the largest possible support surface AF results. In this way, articles P can also be reliably picked up on the longitudinal side of their packaging. This adjustment of the supports 13 can be done electromechanically or pneumatically, both continuously or in predetermined stages, or by replacing the gripper in a gripper changing station.
    Depending on how much space is in the storage container filled with the articles P, storage aid LLH for receiving the to be picked by the control computer (the control device) article P, the control computer, the suction gripper S according to different driving trips to the selected area of the article P move. If the articulated arm gripper 6 has relatively little space for receiving the article P, because the article P is difficult to access, then it has proven advantageous for the kinematic unit K to have the articulated arm gripper 6 with an articulated arm 9 (articulation angle W) aligned in the direction of the longitudinal arm 8 = 180 degrees) positioned immediately in front of the article P to be picked up. Only in this position of the articulated arm gripper 6, as the last positioning before sucking the article P, the articulated arm 9 is bent to the predetermined by the control computer, bending angle W. As a result, the articulated arm gripper 6 can advantageously also be positioned in very inaccessible places in the storage loading aid LLH for receiving an article P. kl
    However, if the article P is freely accessible in the bin loader LLH for the articulated arm gripper 6, then the time to pick the article P from the storage loader LLH into the order loader ALH can be reduced by the articulated arm 9 already during the positioning of the articulated arm gripper 6 by the kinematic unit K is bent by the bending angle W. The angle of rotation can be adjusted independently of the selected Ansteuerfahrt already during the positioning of the articulated arm gripper 6 by the kinematic unit K to the rotation angle DW, since this does not increase the interference contour of the articulated arm gripper 6. By this temporally parallel setting of the kinematic unit K and the articulated arm gripper 6, the throughput of the order-picking system 1 can be increased and the order-picking system 1 thus made more economical.
    FIG. 9 now shows a picking system 15 with an intermediate buffer platform 16 as an intermediate buffer, on which articles P to be picked for 1 to n different orders can be buffered to 1 to n buffer units 17 and 18. The articles P picked up by the kinematics unit K from the respective storage loading aids LLH are deposited on the buffer unit 17 or 18 associated with the order. When all or parts of the item P to be picked for the order are on the buffer unit 17 or 18, the control computer controls a mechanism which tilts the articles P of the tilting surface 17 or 18 into the order loader ALH associated with the order. As a result, a substantial decoupling of the picking up of articles P from the storage loading aids LLH and the dispensing of picked up articles P into the order loading aids ALH is achieved.
    It may be mentioned that as an intermediate buffer, for example, also a platform with a pusher, a plate which is pulled away under the articles P, could serve a funnel-shaped chute including folding control or a slide device including folding control. Furthermore, the number of two Zwischenpuffem is to be understood only as an example, since an arbitrarily large number of intermediate buffers for short-term storage to be picked items to be picked P could be provided. It has proved to be particularly advantageous if individual articles P to be picked, which are sensitive with respect to vibrations or are first picked by the articulated arm gripper 6 directly into the order loading aid ALH, are first picked into the order loading aid ALH because of their size or weight. The other articles P (first group) poured from the intermediate buffering platform 16 into the order loading aid ALH may be poured into the order loading aid ALH before or after the article P (second group) picked directly into the order loading aid ALH.
    It may be mentioned that the joint of the articulated arm gripper can be designed as a ball joint, as a film hinge or according to another type of joint.
    The actuators of the articulated arm gripper can be pneumatically, hydraulically executed with single-acting or double-acting cylinders. It would also be possible to ensure the drive of the articulated arm from a remote servo motor via a cable or a linkage. Furthermore, sensors could be provided on the articulated arm gripper, which monitor both the pivoting movement and the gripping function.
    It may be mentioned that the gripper could also be formed by a different gripper type. Thus, for example, a forceps gripper could be provided which removes the articles P by friction from the Lagerladehilfsmittei.
    It can be mentioned that also more than one article could be picked at once with the gripper.
    It may be mentioned that the kinematic unit could be realized by a delta kinematics, but also by a robot arm or another mechanism known to a person skilled in the art.
