Description

The invention relates to mechanical engineering and can be used to accumulate and transport products in robotic metalworking lines.

The purpose of the invention is to expand the technological capabilities of the device by ensuring the accumulation and movement of products of different sizes.

Figure 1 shows the device, front view; figure 2 is the same, the view in the plan; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 2; figure 5 is a section bb In figure 4.

The device comprises a frame 1, a drive 2, guides 3, on. which are mounted infinitely closed parallel installed conveyors 4 and 5 with slots 6 for placing products 7. Loaders installed in the conveyors are made in the form of two pairs of prisms 8 with a lifting mechanism.

Each pair of prisms is mounted on rods 9, which are mounted on carriages 10. An adjusting screw 11 is provided for fixing the prism 8 to rod 9. Rollers 12 are installed at the ends of the rods.

The prism 8 lifting mechanism is implemented in the form of articulated parallelograms, the rotary links 13 of which are made in the form of double-arm levers, the free ends of which are articulated to the rods 14 and 15 of the two-rod power cylinder 16, rigidly mounted on the frame 1 perpendicular to the axis of the conveyors 4 and 5. In each hinge parallelogram, in the movable main link 17, there is a guide in which the rollers 12 of the rods 9 are located.

In addition, in each carriage 10, the leveling rollers 18 are arranged to smoothly move the rods 9. The carriages 10 and the conveyor 5 are respectively installed in the guides 19 and 20 with the possibility of horizontal movement in a direction perpendicular to the longitudinal axis of the conveyors.

The movement mechanism of each carriage 10 consists of a nut 21 installed in the carriage body, a screw 22 mounted on the frame 1, and a drive 23..

The conveyor movement mechanism .5 consists of nuts 24 mounted on the housing 25 of the movable conveyor 5, screws 26 mounted on frame I, the actuator 27 and the synchronizing chain transmission 28.

The device works as follows.

When the drive 2 is turned on, the conveyors begin to move along the guides 3. At the same time, the slots 6 installed on the conveyors 4 and 5, with the products 7 placed on them, also begin to move in the direction of the load handlers. When the product reaches the first pair of prisms in the course of the movement, the conveyors stop av. laiyuts. The ram 16 is engaged. The force from the rods 14 and 15 is transmitted to the hinge parallelograms. The 4-key main links 17 of these parallelograms are lifted and, through the rollers 12, simultaneously lift the bars 9 with the prisms 8 mounted on them

The product, located above the first pair of prisms 8, is picked up by these prisms and is placed in the working area of the manipulator grips. In this case, the manipulator puts the processed product into the second pair of prisms, and then, the manipulator arm with the grip makes a swinging motion and takes the grip, the product from the first pair of prisms,. After removing the product, the loading cranes are lowered due to the activation of the rod 15 of the double-rod cylinder 16 .

The article located on the prisms 8 is lowered onto the sockets of the conveyors 4 and 5.

The accuracy of supplying the part to the zone of operation of the grippers of the manipulator is ensured by the adjusting screw 11. As the screw 11 rotates, the height of the prism 8 changes.

The readjustment of the device is as follows. According to the program incorporated in the computer, the drive 27 of the movable conveyor 5 is turned on, the rotation is transmitted through the synchronizing chain transfer 28 to the screws 26. Rotating, the screws 26 interact with the nuts 24, moving the conveyor 5 by the required amount, ensuring the movement of the product of the required plate and configuration.

Similarly, changeover occurs prism 8 overheating. According to a given program, the drive 23 is turned on, the screws 22 interact with the nuts 21 and move the carriages 10 along the guides 19 by a predetermined amount. Rollers 12 rods 9 move

on the movable main link of the pivotal parallelogram, made in the form of a guide. When the device is in semi-automatic mode, the setting of conveyors and carriages can be done manually. For this, instead of drives on screw gears, handles are installed.
