SU854845A1 - Method and device for one-by-one separating of workpieces - Google Patents

Description

The invention relates to the mechanization of procurement and relates to the automation of the process of supplying long products, mainly angular, to technological lines.

A known method for the single-piece separation of workpieces, mainly long products, using electromagnetic grippers, including the capture of the workpiece and its movement fl The method is carried out by a device for piece-by-piece separation of workpieces, containing a table for stacking workpieces, electromagnetic grippers mounted on a common base, cut-offs and guides rigidly fixed to mentioned table.

The disadvantage of this method is that it does not provide for the piece feed of oriented blanks.

The purpose of the invention is the expansion of technological capabilities of the method.

The goal is achieved by the fact that after the capture of the workpiece, the latter is oriented by turning on and off the electromagnetic grippers.

device for implementing * the proposed method, the common base is mounted with the possibility of rotation • from the drive in a vertical plane, and the guides are made curved, while the cut-offs are mounted on rails with the possibility of extension.

In FIG. 1 shows a device for implementing the proposed method, General view; in FIG. 2 - the same, top view; in FIG. 3 - cutter; in FIG. 4-6 - options for the position of the gripping workpiece.

The device contains a table 1 for placement on its surface 2 of the rolling package of blanks 3 and stops 4 ^ Table 1 is mounted with the possibility of rotation relative to the horizontal axis 5 by means of a hydraulic cylinder

6-. The common base 7, on which the electromagnetic grips 8 are mounted, is mounted to rotate from the actuator 9 relative to the horizontal axis 10. On the table 1, curved guides 11 are fixed that protect the working surfaces 12 of the electromagnetic grippers 8. Curved guides 11 have a radius of curvature equal to the radius the circumference described by the working surfaces 12 of the electromagnetic grippers 8. On the curved guides 11 are mounted cut-offs 13 mounted in the housing 14 with the possibility of extension ek cam guides 11 by means of the adjusting screw 15 and provided with a spring 16. Between guide 11 and the discharging roller table 17 is placed. step conveyor 18.

And set equal to about half the fault width of the shelf of the workpiece.

The device for implementing the method can be easily automated by installing in the area where the workpiece is oriented, a sensor that gives a command either to turn on the step conveyor or to repeat the cycle.

The application of the proposed method and device will significantly facilitate the work of the operator and automate one of the time-consuming processes, in addition, expanding the technological capabilities of both the method and the device.

(54) SUBSCRIBING A PLANT OF STEPPED DEPARTMENT OF PREPARATIONS AND A DEVICE FOR ITS IMPLEMENTATION The invention relates to the mechanization of harvesting and relates to automating the process of supplying rolled sections, mainly angular, to technological lines. - A method is known for single piece separation of workpieces, mainly fortieth hire, using electromagnetic grippers. including gripping the workpiece and moving it. The method is carried out by a device for single piece separation of the workpieces containing a table for laying the workpieces mounted Electromagnetic grippers, cut-offs and guides fixed on the above-mentioned table, on a common basis. The disadvantage of this method lies in the fact that it does not provide for the single-piece supply of oriented blanks. The purpose of the invention is expansion. Technological possibilities. The goal is achieved by the fact that after the seizure of the workpiece is subsequently oriented by switching on and off the electromagnetic grippers. In the device for the implementation of the proposed method, the common base is installed with the possibility of rotation from the drive in the vertical plane, and the guides are curved, with the cut-off devices mounted on the guides with the possibility of admission. FIG. 1 shows a device for carrying out the proposed method, general view; in fig. 2 - the same, top view; in fig. 3 - cutter; in fig. 4-6 — Positions of the gripping blank. The device comprises a table 1 for placing on its surface 2 rolls of a package of blanks 3 and stoppers 4. Table 1 is mounted to be rotated about a horizontal axis 5 by means of a hydraulic cylinder 3 6-. The common base 7, on which the electromagnetic g} akhvats 8 are fixed, is rotatably mounted from the actuator 9 relative to the horizontal axis 10. Curved guides 115 are rigidly fixed on the table 1 and protect the working surfaces 12 of the electromagnetic grips 8. Curved guides 11 have a radius curvature equal to the radius of the circle described by the working surfaces 2 of the electromagnetic grippers 8. On the curvilinear guides 11 there are fixed cutters 13 mounted in the housing 14 with the possibility of extending across the curvilinear guides 11 by means of a rotary screw 15 and equipped with a spring 16. Between the guides P and the diverting roller table 17 are alternated step conveyor 18. The method is carried out as follows. The package of blanks 3 is placed on the surface 2 of the rolling table 1 and rolled by switching on the hydraulic cylinders 6. Tilting the table 1 towards the guides 11, the electromagnetic grippers 8 are turned on, while one of the blanks is attracted to their working surface 12, and table 1 is deflected to the side limiters 4. Thereafter, the actuator 9 rotates the common base 7 to a certain extent and turns off the electromagnets so that the gripped workpiece 19 is oriented on the cutters 13. In this case, the workpiece can be in one of the positions Q, f or -8. From positions d or b, the workpiece falls back onto the table, since the center of gravity of its cross section is not above the supporting surface of the cutter 13 (in this case, the cycle is repeated), but in position B the workpiece remains on the cutter 13 and subsequently turning the base 6 is fed in the transfer zone to the step conveyor .18 and further to the station. roller table 17. When changing the size of the blanks, the protrusion size of the clipper 13 is adjusted by a screw 15 5 and is set to approximately half the width of the shelf of the workpiece. A device for carrying out the method is easy to automate by installing on a site where the workpiece / sensor is oriented, which gives the command to either turn on the stepping conveyor or repeat the cycle. The application of the proposed method and device will significantly ease the work of the operator and automate one of the labor-intensive processes, in addition, the technological capabilities of both the method and the device are expanded. Claim 1. The method of single piece separation of billets, mainly long products, with the help of electromagnetic grippers, including gripping the billet and moving it, characterized in that, with the aim of expanding technological capabilities, after gripping the billet, the latter is oriented by turning on and off the electromagnetic grippers. 2.
