Description

I 1

It belongs to mechanical engineering, and can be used to automate metalworking and is an improvement to the device according to the author. No. 921790.

The chain of invention is an increase in labor productivity and the expansion of technological capabilities.

This goal is achieved by providing the simultaneous supply to the technological equipment of a section of two or more containers, and the design of the load handling device allows the container to be delivered differently in size configuration at a different level.

FIG. i presents the automated section, general view; in fig. 2 - the same, cross section; in fig. 3 - lifting device of the stacker crane; in FIG. 4, section A-A in FIG. 3; FIG. 5 shows a section BB in FIG. 3; in fig. 6 is a diagram of the operation of the load handling device of the stacker crane; in fig. 7-10 - embodiments of the load gripping device.

The automated part machining area controlled from a computer consists of automated technological units containing a CNC machine t, a machine tool 2 with a gripping head 3 moving along the center line tTamca 1 and a coordinate table 4 moving from the stepper actuator 5 in the direction perpendicular to the line of the centers of the machine 1, container 6 for blanks, finished products, tools, etc.

Above the automated technological units, a rack 7 of a transport accumulation system is installed, along guides 8 of which on rollers 9 a crane-head 10 moves, containing a 1G trolley driven by a horizontal movement and a lifting drive 12 to which on the ropes 13 through blocks 14, the lifting platform 15, the trolley 11 being equipped with guides 16 and 17 for the installation rollers 18 and 19 of the lifting platform 15, and for each loading machine position 20 containing the coordinate table 4 and the container table with tools With the guide, the guides 21 and 22 for the rollers 18 and 19 are installed.

The lifting platform 15 is provided with carriages 23 for a container with load-carrying 24, intermediate 25 and basic 26 sections, the basic sections 5 being rigidly connected to the block 27 of basic sections containing two chain conveyors 28 with a common drive, connected by common shafts 29 fixed to flap x crank levers 30,

 In addition, they are mounted on sub-supports in the extreme intermediate sections 25 of the carriages 23, connected by means of a block of 31 gears and rails with the load-bearing sections 24, and mounted

15 in common to all the carriages 23 of the movable support 32 mounted on the rollers 33 in the rails 34 of the load-lifting platform 15. The movable support 32 is connected by ropes 35 via blocks 36 to a counterweight 37 moving on the rollers 38 along the tracks 39 of the lifting platform 15 connected to the block of the base sections 26 with the help of rails 40 which engage

25 with 41 gears installed in pairs on shafts 42.

When additional carriages are installed using different containers according to the configuration (Fig. 7-10), the intermediate sections 25 of the carriages 23 are connected by strips 43 and 44 (Figs 9 and 10), and when using containers with different base levels under one of the containers carriages fitted nozzles 45

35 with fastener 46 (FIG. 10).

Automated plot works as follows.

The computer commands the microprocessor controlling the stacker crane 10 to take the required set of containers 6 with blanks, tools, etc. from the rack 7 and submit to the machine loading position 20 with the coordinate table 4 and the tool table, while the programs are transferred from the program library of the computer to the machine 1 and the microprocessor controlling the technological unit. The stacker 10 is moved horizontally to the required machine position 20, after it is stopped, the lift drive 12 is turned on, and the lifting platform 15 is lowered on the ropes 13, thrown over the blocks 14, while the setting rollers 18 and 19 are fixed in the guides 21 and 22. After stopping the lifting platform. 15, the drive of the chain conveyors 40 is activated.

the ditch 28, which with the help of crank levers 30 vu (moves the intermediate section 25, which in turn, vj (moves the load-carrying section 24 through the gear unit 31, while the common mobile support 32 moves along with the rollers 33 on the rollers 33 along the guides 34, and by means of the ropes 35, through the blocks 36, the movable support 32 moves the counterweight 37 in the opposite position, which is in the initial position in the center of gravity of the load-lifting rod 15. When the crank levers 30 pass the linear section of the chain conveyors 28, generally the movable support 32 is stopped, and with it the counterweight 37, with these levers, pivoting, raised (or lowered) bazo- O unit 27 sections the shafts 42 held in equilibrium by means of gear racks 40 and 41.

After carrying the curvilinear section of the chain conveyors 28, cranked rachags 30 return the sections of the carriages 23 and the counterweight 37 to their original position, then the Lift Drive 12 raises the lifting platform 15, while the rollers carry 24 sections 24 and lift the lifting platform 15 upwards. 18 and 19 are fixed in the guides 16 and 17 of the trolley 11. After the tare 6 is installed at the position 20, the installer installs the tool and fixture on the machine and gives the command to process, while the machine tool 2 from the original zero position is moved to the coordinate table 4 present in the zero position, and grip 3, remove the workpiece from the container 6 and sets in the machine chuck. 1. From the machine, the container is fed into the storage racks 7 in a similar manner, with the container being fed in both directions. In the period of operation of one machine 1, stacker crane 10 serves the other machines.

When the need arises to install containers on a roller table, simultaneously handle two or more containers (Fig. 7 and 8), special and enlarged containers (Fig. 9 and 10), the block of base sections is supplemented by carriages 23, which are connected with each other by strips 43 and 44, and when using containers with different levels of base on one of the carriages, nozzles 45 are installed with the help of fasteners 46 (Fig. 10).
