Description

The invention relates to transporting devices that transfer products from one position to another, and can be used to transfer workpieces from a conveyor to a gas-cutting table.

The purpose of the invention is to increase reliability in the presence of harmful effects in the loading area.

FIG. 1 shows the device, top view; in fig. 2 is a section A-A in FIG. 1, in the position of the carriage and rod at the beginning of the operating cycle; in fig. 3 - the same, when removing the workpiece; in fig. 4 - the same, before laying the workpiece; in fig. 5 - the same, after laying the workpiece; in fig. 6 is a section BB in FIG. 2; in fig. 7 is a sectional view BB in FIG. 2; in fig. 8 - section GG in FIG. 7; in fig. 9 is a section DD in FIG. eight; in fig. 10 is a section E-E of FIG. 7; in fig. 11 is a section of the LF in FIG. YU.

The device for transferring products comprises a series of transporting mechanisms 1, which transfer the blanks from the feeding roller table 2 to the gas-cutting table 3. The last 3 consists of a cutting frame 4 mounted on the frame 4 of removable ribs 5 and a pallet 6 serving for collecting scale and burr. At the bottom of the gas cutting table, an air duct 7 is mounted with guides 8 along which the carriage 9 moves along the table, enveloping elastic rollers 11 with its rollers 10, providing a channel for passage and forced suction of harmful gases from the cutting zone. The carriage 9 is connected to the gas intake 12.

Each of the transporting mechanisms I comprises guides 13 fixed on the base 14 of the roller table 2, and a carriage 15 mounted in the guides 13 with the possibility of reciprocating motion and coupled by means of a gear rack and pinion 16 with a reversible drive.

A carriage 15 is mounted on the carriage 15, connected to the carriage 15 by means of levers 18 and 19, which form a hinge parallelogram with the carriage 15 and the bar 15.

The rotation of the levers 18 and 19 is limited by the stops on the carriage with quince surfaces that hold the rod 17 at different levels in the extreme positions of the carriage 15.

Gear 14 is fixed on base 14, and gears 21 and 22 are alternately connected to rack 19 on the carriage. The latter are kinematically connected to levers 18 and 19, respectively, by means of mechanisms that include bevel gears 23 and 24, 25 and 26, respectively. , screws 27 and 28, worm wheels 29 and 30, and overrunning clutches 31 and 32. Worm to 27 has a left turn direction, and worm to 28 has a right direction. In this case, the overrunning clutch 31 provides for the transmission of the moment counter-clockwise, and the clutch 32 - clockwise. To provide a trajectory for raising and lowering the bar 17, which is close to the vertical, the gear ratio between the wheels 21 and 22 and the axles of the levers 18 and 19 respectively t

demanding is i -, where t is the length

levers 18 and 19, D - pitch diameter wheels 21 and 22.

On bar 17, a flag is set 33, and on

The base 14 is a sensor 34 for issuing a command for reversing the drive.

The device works as follows.

.Packing 35, served by roller table 2,

stops above shtanga 17 (fig. 2), which occupies its lower position. When the drive is switched on, the rack-and-pinion gear 16 tells the carriage 15 to move to the right along the guide 13. At the same time

0, the gear wheel 21, which is engaged with the rack 20, through the wheels 23 and 25, the worm to 27, the worm gear 29 and the overrunning clutch 31 transmits the rotation of the levers 18 counterclockwise, while raising the rod 17. Due to the selected front, the exact ratio between the wheel 21 and the axis of the lever 18, the rod is mixed in a direction close to the vertical, and removes the workpiece 35 from the roller table 2. At the moment when the levers 18 and 19 reach the surfaces a, the gear wheel 21 comes out of engagement with the rail 20 and the bar begins move together with the carriage moving cooking zone gas cutting in the section 3 (Fig. 3).

When approaching the carriage 15 to the gas-cutting table 3, gear wheel 22 enters into engagement with the rail 20, and the torque from wheel 22 is not transmitted to the axis of the levers 19, since the overrunning clutch 32 operates in the free-wheeling direction.

0 When the bar 17 reaches the zone of the gas-cutting table 3 at the command of the sensor 34, the actuator changes direction of rotation from the action of the flag 33, and the carriage 15 begins to move to the left. At the same time, the gear wheel 22, which is engaged with the rack 20, via bevel gears 24 and 26, the worm to 28, the worm gear 30 and the overrunning clutch 32 transmits the rotation of the levers 19 clockwise, lowering itself with the rod. In the moment,

When the levers reach the surface e, the gear wheel 22 is disengaged from the rail 20 and the rod 17 moves together with the carriage 15 to its original position in the zone of the feeding roller table 2. In the process of approaching the carriage to the roller table, it engages with

5, the gear wheel 21 enters the bar 200, while the steep moment from it is not transmitted to the levers 18 due to the free running of the coupling 31.
