SU97881A1 - Machine for sorting tubes and tubular parts by wall thickness - Google Patents

Description

One of the most important causes of large scrap and large wastes in an electrovacuum production is the lack of machines for sorting tubular glass blanks along the walls.

In the proposed automaton, we provide the possibility of sorting tubes into tubular blanks but thickly and otherwise, using the well-known method of sorting the article: pp by weight.

The peculiarity of the described automaton is that coherence by weight} is provided without any weight and related executive devices, and directly as a result of the direct influence of the weight of the sorted trough, on the position of the rotary beam, different angles (depending on the thickness, wall of the tube) for directing the tubes to different compartments of the receiving bin.

The drawing shows schematically the proposed machine.

Tubes calibrated in length and outer diameter are laid in the hopper. With

pomosh, and c) a gear drum 2, tubes from buicker 1 are fed to a sorting device 3, made in the form of a rocker arm and located under the outlet opening of the drum casing 2. In the initial position, the rocker arm 3 rests on the support 4.

Due to the unequal weight of the tube walls of different thicknesses, rolling down the beam 3, the latter is tilted at different angles. Depending on the well angle of the angle of inclination of the rocker arm, the pipes fall down along different trajectories. A divider 5 is installed along the path of the tubes to the tubes in two compartments 6 of the primer bunker. Thin-walled pipes fall into the left section of the bunker, while thicker walls pipes fall into the right section. To soften the impact of the tubes and even lay them, there are two rubber braking and laying guides 7, and the bottom of the receiving hopper is rounded.

The adjustment of the machine is made by moving the divider 5 to the left or to the right, as well as by moving the weight S, fixed on the yoke 3 ...

To achieve greater precision in sorting, tubular parts are passed through several appropriately configured automats. Subject invention

1. A machine for sorting tubes and tubular parts by wall thickness, comprising a loading hopper for tubes calibrated in length and outer diameter, a rotating toothed drum for feeding the tubes from the loading hopper to the sorting device and a receiving bin with two compartments different in that

that, in order to simplify the construction, the sorting device is made in the form of a rotary beam, located under the outlet of the drum casing and deviating under the action of the weight of the tube fed by the drum, different angles depending on the thickness of the tube wall to direct the tubes to different compartments of the receiving bin.

2. The device of claim 1, characterized in that in order to mitigate the impact of the tubes when they fall into the receiving bin, the rezipovye guides are located on the path of their movement from the rocker arm to the bunker.
