Description

products into the stacker, the function of a free-standing technological macaw for laying pressed products.

The purpose of the invention is the expansion of technological capabilities, providing a shorter time cycle of the technological process for the production of presses, ensuring better preservation of the cutting edges of pressed products from powder materials, when they are still soft, and easily subjected to scratches, chips and other defects, reducing the number of mechanisms and ensuring amenities, ease of debugging processes of functioning of the complex for pressing powder products,

In FIG. Figures 1-3 show an automated complex, a complex joint, consisting of a gripper drive and two mechanisms: a mechanism for removing products from the pressing zone and a mechanism for fixing the plates of transport plates.

The proposed device contains:

I - gripper drive, includes: 1 - additional gripper cylinder, 2 - robot gripper housing, 3 - articulated mechanism with movable levers;

II - a mechanism for removing pressed items from the pressing zone, consisting of: 4 - housing for the mechanism for removing pressed products, 5 - guides for the slider, G - slider, 7 - vacuum pipette (suction cup), 0 - air duct to the vacuum suction cup, 9 - an earring, 10 - the axis of attachment of the cylinder rod earring to the slider, 11 - the rod (piston) of the ram slide cylinder, 12 - the power cylinder housing, 13 - the housing earrings, 14 - the axis of the power cylinder attachment to the body of the removal mechanism, 15 - check flag, 16 - non-contact position sensor;

- III - the mechanism for fixing the drives of transport plates, consisting of: 17 - gripper brackets, 18 - joystick jaws, 19 - sensor mounting bracket, 20 - non-contact position sensor, 21 - rod with a rectangular groove, 22 - washers, in the amount of two pieces, 23 - springs, 24 - nuts for mounting the proximity sensor, two pieces, 25 - hollow threaded sleeve, 26 - cotter pin for mounting the sleeve to the rod, tactile device, 27 - control flag, 28 - control flag, 29 - strap for fixing on the case proximity sensor sensor side of the mechanism for laying transport plates, 30 - non-contact sensor.

The device operates as follows.

Grip 1 of the robot with the mechanism II of removal of the product approaches the pressing zone at the time of lifting the press tool up, to the upper final state, and on command

air is supplied from the press control circuit, under the action of which the rod of the power cylinder 11 through the earring 9 and the axis 10 moves the slider b along the guides 5 directly into the pressing zone of the press to

0 stop, and the suction cup (pipette) 7 captures the pressed product. Then, air is fed into the master cylinder 12 in the opposite direction, and the slider 6 along the guides 5 starts to return to the initial position 5. In this case, the flag 15, mounted on the slider, enters the contact zone of the sensor 16 when the slider reaches its initial position, and it triggers and gives an enable signal

0 to the press control circuit for a new cycle of work.

In the reverse movement, if the flag 15 has not reached the initial position, then the proximity sensor 16 does not work, and in

5, the press control circuit will generate an alarm prohibiting a new pressing cycle, since the previously pressed product has not been removed. - With the normal end of the slider movement of the slider 6 at the moment the proximity sensor 16 is triggered, the robot control circuit will also receive a command to move the gripper to the transport plate, after which the pressed

5 the product will be stacked by the robot. A signal for counting the filling of the plate will be sent to the circuit for counting the number of articles laid on the transport plate, after which a signal will be received to move the gripper (with a pick-up mechanism) again to the pressing area of the press and so cyclically until the entire transport plate is filled.

After the signal will be generated that the transport plate is full,

5, a signal arrives at the operation of the technological packaging installation mechanism, through which the second gripper mechanism III will come into effect; the jaws of the gripper 18 through the brackets 17 will be inserted about the center of the transport plate and triggered by a tactile device (jaw position sensor relative to the container), consisting of a mounting bracket 19, a proximity sensor 20 of the position, the rod 21,

55 washers 22 springs 23, nuts 24 and bushings 25,

cotter pin 26, flag 27, which when oppa. in the divided position of the transmitter, the moment when the jaw 18 of the robot grip

are in the slot of the transport plate.

The proximity sensor 20 will issue a circuit

control signal for the extension of the jaws 18 through the pneumatic cylinder 1 and the hinge mechanism 3.

The state of normal extension of the jaw jaws 18 (monitoring the position of the jaws inside the plate slot) is fixed by means of a flag 28 fixed to the lath 29 of the jaw body 2, while the proximity sensor 30 will give a signal at a certain position from the flag 28. According to this signal, the transport plate, if it is completely filled, will be transported to the stack-drive, and a free transport plate will be installed on this place with the same grasp.

On the guide elements in two extreme positions, elastic elements are fixed in the form of flat springs, which provide a clear fixation of the creep when moving the latter by the power drive, ensuring a stable position of the cushion and a good grip of the pressed blanks.

Such a constructive implementation of the complex provides a reduction of ... the required time by. auxiliary operations of the technological process, i.e. provides increased productivity, reduced material consumption of the structure ..

The invention provides a significant expansion of the technological capabilities of the complex for servicing several zones of the press, provides a significant economic effect from increased productivity, and saves material on mechanisms and their operation.
