Description

(S) DEVICE FOR DAILY DISTRIBUTION

The invention relates to the field of automatic orientation of parts, to devices for fixing them in the capture zone by an industrial robot.

According to the main auth. No. there is a device for the piece-by-piece delivery of parts containing a storage tray, spring-loaded sash, a profile bracket located in the drive tray window with the possibility of diagonal movement relative to its planes and connected to a rod that is kinematically connected with spring-loaded sashes fixed on the tray- drive with the possibility of rotation tj.

However, the device has insufficient positioning accuracy due to the rigid coupling of the device with a vibration drive. This makes it difficult to use the device in precise and precise technological processes (for example, in assembly operations), since the interaction of DETAILS

devices in the complex, with the capture of an industrial robot ensures reliable operation in process automation, limited to the middle class of accuracy.

The aim of the invention is to improve the accuracy of the positioning of parts relative to the capture of an industrial robot.

This goal is achieved by

10 that the storage tray is made up of fixed and movable parts, the device is equipped with an additional drive, which is kinematically connected with the moving part of the tray-feeder mounted on the guides with the possibility of vertical movement and fixation.

Figure 1 shows the proposed device; in figure 2. - drive about 20 filing brackets.

Claims (1)

The device for single delivery of parts consists of a storage tray 1 fixed on the base 2c 3 by means of a flat spring 3, a movable tray connected to the base plate 5 by means of guides 6 and 7- A cylinder 8 for lifting the tray C fixed to the base plate 5, The headless cavity of which is connected to the power mains with the npo-manipulator control device (not shown). On base 9, flat springs 10 and 11 are fixed, holding back support plate 5. Holes 12 are made in the movable tray for clamps 13 rigidly fixed on the base 9. The connection of the tray-to the hopper I with the movable tray k is of gear-type and force-operated. 1 and 15 which interact with the guides 6 and 7 and the base plate 5. Parts 1b are located on the tray accumulator I and the movable tray 4. The stand is secured to the stand by the support 17 of the support brackets 18 and 19 of the stop 20 and the cylinder 21 of the diagonal movement of the profile bracket 22 relative to the tray k. On the support bracket 19, the left post 23 is fastened. In the right 17 and left 23 posts, the shutters 24 and 25 are rotatably mounted, which are pressed against the support bracket 19 by springs 26 and 27. The device 1 operates as follows. Along drive tray 1, the curved parts 16 are transported to the grip area. The extreme right part 16 is braked by the stop 20 and occupies the required position, supported by its end surface on the profile of the stop 20. Between the extreme right and following details 1b, it goes diagonally into a special window of protrusion beyond the plane of the movable tray, the profile bracket 22. Moves the profile clamp 22 cylinder 21 on command from the manipulator software control device. Thus, the second part 16 is unambiguously fixed at the sense of k. Then the cylinder 8 lifts the tray k vertically upwards, disconnecting it from the storage tray 1 by an amount due to the length of the guides 6 and 7. The locking pins 13 enter into the apertures 12, providing rigidity and excluding the displacement of the tray t relative to the base 9. the surface of the tray C, the protrusion above the plane of the storage tray 1,. 4 performs the function of a shutter and impedes the advancement of parts; the gripper of a manipulator (not shown) clamps two components 16 simultaneously and lifts them vertically upwards. At the same time, the parts 16, acting on the flaps 2 and 25, lift them, compressing the springs 25 and 26. After removing the details 16 from the tray k of the flap 2 and 25, the profile bracket 22 and the tray C itself return to their original positions with the help of springs 26 and 27, cylinders 21 and 8. The kinematic connection of the tray t with the base 9 is broken and contact with the storage tray 1 is established. Details 16, under the action of vibration, slip into the positioning zone and are fixed by the support bracket 18. Next, the cycle is repeated. The use of the proposed device allows to expand the scope of complex automation of production processes by switching from medium-precision to high-precision processes, and after a small improvement (by adding an additional profile bracket with a drive) to increase productivity. This significantly expands the functional properties of the device and allows, in addition, to vary the performance in a wide range by capturing one, two or at the same time three parts. The device can be used as part of the gripper of the manipulator, eliminating the need for a mechanism for supplying the gripping bodies to the part. Simplification of the gripper design reduces the weight of the manipulator, allowing either to increase productivity with constant accuracy, or to apply the complex to precision processes at constant performance. The performance of the movable chute function of the trimmer simplifies the design of the mechanism. Claims of the invention A device for the piece-by-piece delivery of parts according to ed. No. characterized in that, in order to improve the accuracy of positioning of parts, the device is equipped with an additional drive, and the tray collector is made of a composite
