    An apparatus for feeding workpieces to a workpiece gripping position of a hand of an industrial robot, especially a workpiece feeder used for a limited axis robot, comprises a conveyor (3-5) which is mounted on a table (100) and has a plurality of pallets. Workpieces placed on the pallets are movable intermittently to a predetermined area of the robot, e.g. to a window in the table (100). Each of the pallets comprises a lower plate (202) having a central opening and an upper plate (201) mounted on the lower plate (202), and there is provided a lifting means (13) movable vertically through the window in the table (100) and the central opening in the lower plate (202), causing the upper plate (201) to move and to lift the workpiece placed on the upper plate (201) up to a workpiece gripping position of a hand of the robot.

    The invention relates to the automation of process equipment and can be used to sequentially feed the blanks to the coverage of the robot.
    The purpose of the invention is to increase the feed accuracy by eliminating the skew of the blanks as they move from the pallet to the coverage of the robot.
    FIG. 1 shows a device for the sequential supply of blanks to the coverage of a robot, a general view; in fig. 2 is a view A of FIG. one; on fig.Z - the mechanism of lifting billets to reach the robot; in fig. 4 - plate; figure 5 - subzone; in fig. 6 is a view B in FIG.
    The device for the sequential supply of blanks contains a frame 1 on which table 2 is fixed. On the floor 2 there is a horizontally closed conveyor 3 mounted, enveloping sprockets 4 and
    5, fixed, p. possibility of rotation on the table 2. The flexible conveying body of the conveyor is made in the form of a chain.
    6. The pallets 7 are cantilevered on the chain 6 kbnveyer 3 with uniform pitch from each other.
    The horizontally closed conveyor 3 is set in motion by electromotor 8 via gears 9 and 10, the latter being mounted on the shaft 11 sprockets 4. The star, 5 is mounted on the shaft 12. The shafts 11 and 12 sprockets 4 and 5 are installed in frame 1 bearing assemblies are respectively 13 and 14. In frame 1, under table 2, a billet lifting mechanism 15 is installed, comprising a platform 16 with guide rods 17 fixed on the underside of platform 16 and serving to prevent the platform 16 from rotating when it is raised and lowered.
    In the center of the platform 16 is installed the housing 18, made in the form of a cylinder. A nut 19 is fastened at the lower end of the housing 18. The screw 20, screwed into the nut 19, passes vertically through the housing 18. The asterisk 21 is mounted on the lower part 50 and passes through the window 38 in the table 2 and the driving screw 20. The lower end of the window 26 pallet 7, and pins 33 of the board - 20 is connected to the brake
    screw 20 is connected to 22. The lead screw 20 has supports for rotation, sprocket 21 bends around chain 23. The latter spins around sprocket 24, mounted on the shaft of the servomotor 25. In each pallet 7, a window 26 is made to pass through it platform 16 of mechanism 15 the molds 16 enter holes 32 made in the lower plane of the plate 27.
    55 When the upper surfaces of the stacked blanks 28 reach the level of the light source 34 and the photocell 35, the light beam between these two parts is interrupted, causing the blanks to remain. On each pallet, a plate 27 is loosely mounted, intended for laying blanks on them -28. With the lower plane of the plate 27 facing the pallet 7, the holes 29 and 30 are diagonally made. On the pallet 7, the pins 31 are arranged diagonally, respectively, the holes 29 and 30.
    In the center of the bottom plane of the plate 27, two holes 32 are made, and on the platform 16 of the lifting mechanism 15, the pins 33 are arranged, respectively, a hole 32 and 32. At the level of the corresponding setting position of the workpiece 28, a source 34 of light and photo element 35 are installed by a robot hand.
    Light source 34 and photocell 35, i.e. Photo sensor are not separately connected units, but may be connected. to the arm of the robot directly.
    The frame 1 is mounted on the support legs 36, and on the table 2 are mounted the limit switch 37, which determines the stopping position of the pallet 7 ,.
    In the hall 2, a window 38 is made for the passage of the lifting mechanism 15. The device works as follows.
    . Chain 6 horizontally closed conveyor 3 with attached to it
    The pallets 7 are driven by the electric motor 8 and stop at a predetermined position as a result of the operation of the limit switch 37 setting the position of the pallet 7. Then the servomotor 25 of the lifting mechanism 15 is turned on. The rotation of the servomotor 25 is transmitted to the spindle 20 via sprockets 24 and 21, around the chain 23. Rotating the spindle screw 20 leads to lifting the nut 19j screwed onto the spindle 20. The housing 18, on the lower end of which the nut 19 is mounted, is also lifted along with platform 16. As a result, platform 16
    50 passes through window 38 in table 2 and window 26 in pallet 7, and pins 33 of board
    forms 16 enter holes 32, made in the lower plane of plate 27.
    55 When the upper surfaces of the stacked blanks 28 reach the level of the light source 34 and the photocell 35, the light beam between these two parts is interrupted, causing a 3
    The engine and the instantaneous stop of rotation of the lead screw 20 by the brake 22, thereby stopping the rise of the plate 27.
    Thus, if the light source 34 and the photocell 35 are preset at a level corresponding to the gripping position of the workpiece with the robot hand, the workpieces 28 are successively transmitted to the gripping position of the workpiece with a robot hand (not shown).
    After the last workpiece 28 has been removed by the robot arm from the plate 27, the platform 16 is lowered. The plate 27 is placed on the pallet 7 and the pins 30 and 31 located on the pallet 7 enter into its holes 29 and 30, the Platform 16 is lowered to its original position, and the cycle is repeated.
