Description

The invention relates to a machine-building and can be used in the automation of production processes, for example, in installations on production lines of linear production.

The purpose of the invention is to increase the reliability of the conveyor.

FIG. 1 shows a general conveyor, a plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 - node I on

fig o 2; in fig. 4 — node II in FIG. 1 in FIG. 5 is a section BB in FIG. four.

The carousel conveyor contains, becoming a platform 15 which is rotatable relative to the bed 1 platform, consisting of nine working elements 2 arranged in increments along the circumference. Vertical axis 3 is located on frame 1. Each working element 2 is connected to vertical axis 3 by means of a horizontal beam 4 and rests on rollers 5. Beams 4 are connected to vertical axis 3 through a central rotary element with bearing 6 installed on frame 1. On frame 1, which rests on frame 1 and pillars 8, there is a bracket 9 with an actuator mounted on it, designed in the form of a power cylinder - hydraulic cylinder 10 Pri. This, on the frame 7, there are fixed guides 11. In fixed directions 11 is moved by the slider 12 with the protrusion 3, with the protrusion 13, the anvil 14 and the pushing element hinged on it, which is made in the form of a vertically disposed position hinged on the 15 axis of the pushing two shoulders . At the same time, the upper end of the pushing lever 16 is arranged to cooperate with the stop 14, and at the lower end of the lever 16 there is a stop roller 17, which is rotatable around its longitudinal axis, which is mounted with the possibility of alternate interaction with the side surfaces of the beams 4.

The thrust roller 17 has a spherical surface for better disengagement from the beams 4. The beams 4 are connected to the central pivot element in which the bearing 6 is placed, by means of axes 18. On the frame 7 also mounted bracket 19, on which the axis 20 is fixed, on

with which the fixing element is hinged in the form of a two-arm fixing lever 21 with an offset center of gravity.

At the upper and lower ends of the two shoulders lever 21, pivoting rollers 22 are mounted around the longitudinal axis of the fixing two shoulders lever 21, which also have a spherical surface.

The two-arm locking lever 21 is located relative to the lever 16 at a distance allowing the platform to make a turn of one position. The lever 16 is fixed by the stop 14 when the working stroke of the hydraulic cylinder 10 and free when idling.

In the initial position, it is located at a distance L from beam 4 of one of the nine working elements of 2 platforms. The size L depends on the radius R, the circumference of which should not touch beam 4. It is taken from the calculation of the center of gravity of the lever 16 and roller 17 below the center of axis 15. In the leftmost position of the slide 12, the protrusion 13 is positionable to interact with the upper fixing roller 22, and the lower fixing roller 22 is mounted to cooperate with other side surfaces of the beams 4.

The conveyor works as follows.

The hydraulic cylinder 10, leaning through the bracket 9 on the frame 7 and the pillars 8, begins to move in the direction of 11 the slider 12 with the lever 16 located on the axis 15. The roller 17, resting on the beam 4 and rolling along it, starts rotate the beam 4, while the upper part of the lever 16 abuts against the abutment 14. With the help of the axes 18, the remaining eight positions of the working elements on the central pivoting element rotate up to the abutment of the beam 4 into the lower roller 22 of the lever 21, and the protrusion 13 - into the upper roller 22 lever 21. As a result, all nine positions of the working elements of the platform will be chickpeas at a certain angle and locked.

When idling the hydraulic cylinder 10 (back), the lever 16 freely bends around the roller 17, the beam 4, and after leaving the engagement with it returns to its original position, since the center
