A known automatic line for processing locks of blades, containing an installation for melting an alloy with metering devices and mechanisms for producing briquette, machines for processing locks of blades, a transport system with single-piece mechanisms, connecting an installation for melting an alloy with machines for processing locks of blades, mechanics rotation of briquettes and the mechanism for unloading finished products, located in the installation for melting alloy 1J. The disadvantage of the known line is the limited operational capability. The aim of the invention is to improve the operating conditions of an automatic line for processing locks of shovels. This goal is achieved by the fact that in an automatic line for processing locks of blades containing a plant for melting an alloy with metering devices and mechanisms for producing briquettes, a mill for processing locks of blades is to be transported. a system with mechanisms for piece delivery, connecting the installation for melting the alloy with the machines for processing the padlocks, the mechanism for returning the briquettes and the mechanism for unloading finished and The equipment placed in the melting unit of the alloy, the unloading mechanism for finished products is made in the form of a tank with holes with a tapping tray, installed with the possibility of rotation in the vertical plane and sequential interaction with the mechanism of briquette return and additionally introduced into the device of the gravitational tray, fixed from the outside of the plant to melt the alloy. . FIG. 1 shows the automatic line in the plan; in fig. 2 is a section A-A in FIG. 1; in fig. 3 is a section b-B in FIG. one; in fig. A - section BB in FIG. 2; in fig. 5 is a section of YYD in FIG. 2. The automatic line contains machines 1 for processing locks of blades, a rotary-dividing table 2 on which devices 3 for clamping briquettes 4 with blanks are fixed. The number of devices 3 on the table 2. Corresponds to the number of positions of machine tools 1. Opposite each working position in the technological equipment of the machine 1, a power table 5 is installed with a processing head 6 on which a cutting tool (not shown) is attached. Before the loading position of the machine 1 there is free space. The automatic line also contains an installation 7 for melting the alloy, which has a tank 8, placed in the casing 9. Between the tank 8 and the casing 9 there is heat insulation 10. The tank 8 is filled with coolant. In the lower part of the tank 8 installed heaters 11, for example, electric type heater. A tank 12 for the alloy is fixed inside the tank 8 above the heaters 11. Bath 12 is fully immersed in the coolant. Water is used as a coolant for the VUD alloy, and oil is used for the bismuth-tin alloy. In the tank 8, metering devices 13 are installed, connected to the alloy bath 12 and connected to the cream faucet 14 through a control valve 15. The dosing device 13 has a mechanism 16 for controlling the flow rate of the alloy. The alloy melting unit 7 also contains mechanisms 17 for producing a briquette, which have cassettes 18 and 19 for casting the billet and producing briquettes. The cassettes 18 and 19 have holes for the passage of the pushing rods 20 and 21. Each cartridge 18 and 19 has a movable wall 22 and 23 driven by the mechanisms 17 for producing briquettes and sets of pins 24 and 25 for distribution. allowance. The actuator and mechanism for pinning the pins 24 and 25 are not shown in the drawing. The cassette 18 is shown with an open wall 22. The briquette 26 is pushed out after casting the blank with the alloy. The cassette 19 is closed by the wall 23. The cassette 19 is equipped with the blank 27 and the allowance is distributed, which is indicated by the folded pins 25. The cassette 19 is prepared for casting the blank 27 alloy. Both mechanisms 17 for receiving a briquette are mounted on a common table. In addition, the automatic line contains a transport system linking the installation 7 for melting the alloy with the machines 1, consisting of roller conveyors 28 with gripping mechanisms 29 and with a drive 30, piece-output mechanisms 31, made in the form of carriages 32 with drives 33, and also a manipulator 34 located between the machines 1 with the possibility of transferring the briquettes from the roller conveyors 28 to the machines 1 and from the machines 1 to the mechanisms 35 for returning the briquettes 26 to the installation 7 for melting. The mechanism 35 for returning the briquettes to the installation 7 for melting the alloy is made in the form of two trays 36 and 37. One tray 36 is fixed obliquely to the installation 7 for melting the alloy. The other tray 37 is mounted obliquely to the automatic manipulator 34 and is equipped with a rotation actuator 38 around the horizontal axis of the hinge 39. In the tray 36, a valve 40 is mounted with a latch 41. In addition, the automatic line is equipped with an installation 42, for example, a rotor type for removing burrs from the workpiece . This installation is connected to the installation 7 for melting the alloy by transporting the device 43 and has a mechanism for loading billets (not shown). Plant 7 for melting the alloy has, as a briquette accumulator, a tank 44 with a discharge tray with a turn actuator 45, which functions as a device for unloading billets after the briquettes are melted. The tank 44 is installed in the tank 8 above the bath 12 and has openings for the alloy to exit and for draining the coolant to rotate it to unload the blanks on the gravity tray 46. The alloy melting unit 7 can be equipped with an electric pump 47 for circulating the coolant through the tank 44 during smelting blanks from briquettes. The roller conveyors 28 are equipped with sensors 48 and 49 for the presence of briquettes in the respective carriages 32. Common for both roller conveyors the receiver 50 of briquettes is equipped with an adjustable stop 51. The automatic line is perpendable and works as follows. Each machine 1 for machining padlocks sets up processing of padlocks of compressor blades. At the same time for machine tools -1 choose the same different size of the blades. In accordance with the chosen blade size, the required cassettes 18 and 19 are installed into the mechanisms 17 for producing a briquette for casting blanks with the alloy and producing briquettes. Sets of pins 24 and 25 of the mechanisms 17 for producing a briquette are set to the size of the blades. In the bath 12 of the installation 7, the alloy is melted by means of electric heaters 11 and a heat carrier. The dosing devices 13 are adjusted by the regulating mechanisms 16 to the alloy rate specified for each cartridge 18 and 19. The alloy in the cassettes 18 and 19 is fed through the corresponding valve 14 when the control valves 15 are turned on. Before pouring the alloys into the cassettes 18 and 19, workpieces are installed in them and the stock is automatically distributed in a cassette closed with a movable wall 22 and 23 using sets of pins 24 and 25 The blanks are inserted into cassettes 18 and 19 alternately: first into one cassette 18, and then into another 19. The casting of the blank with alloy occurs automatically after the end of the process of distribution of the stock. When cooled, the alloy hardens and a briquette 26 is obtained with the billet. After the hardening of the alloy has finished, the movable wall 22 moves away from the cassette 18, and a grip 29 is inserted between this wall 22 and the cassette 18. The cassette 18 is released from the briquette 26 using the ejector 20. By the reverse movement of the grip 29, the briquette 26 is loaded onto a roller conveyor 28. Briquette 26 slides along the roller conveyor 28 and into the carriage 32. Subsequent briquettes 26 obtained in the cassette 18 are also unloaded onto the roller conveyor 28, and these briquettes 26 accumulate one after the other in front of the carriage 32 at the bottom of the roller conveyor 28. Similarly, they load Ricket to another carriage 32. Only here after casting alloy preform 27 in the cartridge 19 and for producing the preform 26, the last ejector 21 is discharged from the cassette 19 after retraction of the movable wall 23 and the gripper 29 when the actuator 30 is fed to the conveying device. All described operations are carried out automatically.

The presence of briquettes in the carriages 32 is signaled by the corresponding sensors 48 and 49. The carriages 32, using their drives 33, feed the briquettes individually into the receiver 50. The manipulator 34 picks up the briquette 26, which is in the middle position relative to the loading positions of the process equipment 1, takes the briquette 26 of receiver 50 and sets it in accordance with a predetermined program into device 3 of machine 1. When gripping briquette 26 in receiver 50, the manipulator 34 fills the briquette 26 to the stop 51, ensuring that the position of the briquette 26 is identical during loading and installation machine 1. After the preform 26 to the corresponding device 3 automatically preform 26 is clamped in this device 3, and the manipulator 34 returns to its original position.

In machines 1, devices 3 with clamped briquettes 26 are automatically moved by means of rotary-dividing tables 2 from the loading position to the working position and from one working position to another. At the working positions of the machines 1, the lock of the blade filled with the alloy in the briquette is processed. Processing is performed after automatic movement on the power tables 2 of the processing heads 6 with the cutting tool in the direction opposite to the tables 2 of the fixtures 3. At the same time the heads 6 make first fast approach of the tool to the briquettes 26 clamped in the fixtures, and then transferred to the working feed with the removal of the allowance from the blade lock protruding from the briquette 26, each head 6 of machines and technological equipment and 1 has its own insight, tuned to perform a specific operation, for example, milling the front surfaces of the lock, then the soles, sides of the sides, baldness and pulling the profile of the lock. In accordance with the standard size of the blade being processed, each machine 1 has its own period of processing the workpiece, i.e. own cycle of work associated with the longest operation performed on the machine. After performing such an operation, a machining head with a tool that removed an allowance for this operation.

moves away from the device with the workpiece in briquette 26 and the next rotation of the dividing table 2 takes place with the change of the adaptation of 3 working positions. In this case, the device with machined workpiece in the briquette, which has passed all the working positions, again goes to the loading position of the machine tools 1. A new processing cycle on the corresponding machine 1 starts with turning the dividing table 0 2 and all the processing heads 6 with the tool to the tools 3 to hold in them with briquettes 26 with seals. The manipulator 34 removes the billet 27 of the machine 1 processed in the briquette 26 and transfers said briquette 26 to the briquette return mechanism 35. Immediately after unloading the briquette

0 26 with the processed billet onto the briquette return mechanism 35, the manipulator is .34 lowered down and takes the next briquette 26 from the receiver 50 for loading onto the appropriate stand 1.

I will remove the blanks processed in the briquette from the machines 1 when the latter are loaded with new briquettes 26, o-. There is a manipulator 34 on a certain cycle, fixed for each machine in its own software device. Therefore, the manipulator 34 may not follow the sequence in the operation of the machines 1, and all

The workpiece processed in a briquette is removed 5 times from one or another machine 1, for which in carriage 32 there is a briquette 26 with a workpiece 27, which is indicated by sensors 48

0 or 49, and in which the rotation of the dividing table 2 occurred with the transfer of the device 3 from the billet 27 processed in briquette 26 to the loading position after the completion of operations for processing its lock.

The briquette return mechanism 35 supplies the briquette 26 with the treated billet 27 to the installation 7 to melt the alloy. At the same time, the drive 38 turns the tray 36 around the horizontal axis of the hinge 39 connecting the movable tray 36 inclined to the manipulator 34 with the fixedly mounted tray 37 mounted inclined to the installation 7 for melting the alloy. The briquette 26 with the processed workpiece 27, after raising the tray 36, rolls down the trays 36 and 37 and

 t

through the window in the unit 7 for the melting of an alloy, covered with a valve 40, falls into the tank 44, immersed in the coolant. In the tank 44, the briquettes 26 melt with the processed blanks 27 and accumulate them as they arrive from the working machines 1. To accelerate the melting of the briquettes 26, they turn on the pump 47 supplying the heat carrier to the tank 44. The alloy obtained as a result of melting the briquettes is drained through holes in the bottom of the tank 44 into the bath 12 below it, from which this alloy is fed to the filling of new briquettes, as described above.

After filling the container 44 with the billet 27, the locking 41 of the shutter 40 is automatically turned on. Now the briquettes 26 with the processed billet 27 are accumulated in the tray 37. This ensures a complete

039938

melting of blanks from briquettes that were last delivered to tank 44, due to a matched time. The blanks 5 freed from the alloy by turning the container 44 are unloaded onto the gravity tray 46, through which they enter the installation 42 for removing burrs.

Meanwhile, the tank 44 is returned to the coolant and shut off

the latch 41 of the flap 40, and the briquettes 26 accumulated in the tray 37 with the processed billets 27 are rolled into the tank 44 for melting. With 15 this in the tank 44 continue to receive such briquettes from machines 1.

Such a constructive implementation of the mechanism for unloading the finished padlock locks allows fully automating the unloading of the finished padlock locks and ensuring a closed automatic cycle for processing the padlock locks.
