SU742296A1 - Receiving-despatching station of pipeline pneumatic transport system - Google Patents

Description

I

The invention relates to pneumatic conveying, in particular to receiving and sending stations of pipeline container pneumatic conveying systems.

A receiving-sending station of a pipeline container pneumatic transport system is known, comprising a chamber with an air duct, spring-loaded single-acting grippers and a stopper located inside chamber 1.

However, such a station only fixes the container and does not provide for its automatic unloading.

The purpose of the invention is to provide automatic unloading of containers.

This goal is achieved by the fact that the spring-loaded clamps are mounted for movement along the duct axis and at least one of them is provided with a finger, and the stopper is designed as a spring-loaded rod with a notch for the finger, and the air duct has a damper kinematically connected to the stopper rod.

FIG. 1 shows the receiving and departure station B when the container is transported; in fig. 2 - the same at the time of unloading the container.

The receiving-departure station contains a duct 1 mated with a transport duct and having a hatch 2 with a flap 3 for passage of the ampoule 4, which is carried by the container 5.

5 Above the hatch 2 are spring loaded

clamps 6, having bevels for passing the container 5 only from the side of the hatch 2. The clamps 6 are located in the housing 7 suspended on the springs 8. On the duct 1, along its axis, there are grooves 9 for clamps 6. On the side of the non-through part of the clamps 6, on A distance 10 is provided for holding the container 5 in the open position. It is located in the housing 11 with a spring 12 fixed on the air duct 1. An aperture 13 is provided for the stopper 10 on the air duct 1. The stopper 10 is connected by a thrust 14 to the flap 3 and has ring undercut 15.

On the housing 11 there is a guide 16 for the finger 17 fixed on the core 20 of the adapter 7.

Claims (3)

To seal the grooves 9 and the hole 13, a casing 18 is provided with a sealed hole for the thrust 14. For monitoring the passage of the container 5, a sensor 19 is installed between the hatch 2 and the housing 7. To control the unloading of the container 5, a sensor 20 is installed. packed in an ampoule 4 or an empty ampoule approaches the receiving and departure station from the hatch 2 side, the device passes inside the duct 1 and acts on the sensor 19. The sensor 19 sends a signal and the air flow is reversed by means of a pneumatic rifle (not showing ana) and opening the flap 3 hatches 2. When the flap 3 is rotated inside the air duct 1, around its axis, the hauling 14 is loosened and the stopper 10 is released, but it is still held by the finger 17. With a counter-flow of air, the container returns, sits on the latch 6, the housing 7 changes, stretching the spring 8 and the finger 17 leaves the annular recess 15, finally releasing the stopper 10, which under the influence of the spring 12 through the hole 13 enters the cavity of the duct 1. The springs 8 return the housing 7 with the latches 6 and the container 5 back. The container 5 with an open cavity is distributed between the stopper 10 and the latches 6. Ampoule 4 with a sample or empty through the flap 3 through the hatch 2 falls out of the container 5 (see Fig. 2). At the same time, the ampoule 4 acts on the sensor 20, which gives a signal for reversing the air flow with a pneumatic rifle (not shown) and closing the hatch 2 with a flap 3. The flap 3, by closing the hatch 2, by the grip 14, removes the stonor 10 from the cavity of the duct 1, compressing the spring 12. Thus, the container 5 is released and the air flow is carried away in the same direction. It moves under load. The springs 8 are compressed, move the body 7 with the latches 6 and the finger 17. The finger 17 along the guide 16 enters the recess 15 of the stopper 10. The receiving-sending device can also work in the loading mode. In this case, the device is rotated 180 °, and the flap 3 of the hatch 2 opens to the outside of the duct 1. Claim of the invention The receiving and sending station of the pipeline container pneumatic conveying system, comprising a duct chamber, spring-loaded single-acting grippers and a stopper located inside the chamber, characterized by that, in order to ensure the automatic unloading of the containers, the spring-loaded grippers are mounted with the possibility of movement along the duct axis and at least one of them is equipped with a finger m, and a stopper formed as a spring-loaded rod with a finger recess, the air duct has a flap, kinematically associated with the rod stopper.
