RU2384509C2 - Facility for unloading items of low durability from package - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: facility consists of rotary driven mechanism containing forks whereon package is placed and of guides mounted on forks; carriage with cover (6) travels along guides. The cover is equipped with rotary blades (8) which can be fixed in a closed position by means of lever (9) with pneumatic cylinder (10). Space inside the movable cover is divided into several volumes with partitions coated with elastic material.

EFFECT: facilitating automated unloading items of low durability from package without damage.

Description

The invention relates to the field of mechanical engineering, in particular to the construction of hoisting-and-transport machines, and can be used for unloading low-strength products from containers in the manufacture of products from powder materials: in powder metallurgy, chemical and other industries.

A product tilter is known, including two mutually perpendicular supports mounted on a frame rotatable from the drive, on one of which a latch is mounted movably on the rails from the drive screw, and a safety stop mounted on the frame, equipped with an additional drive latch, movably mounted on the second support by means of additional rails, in this case, one of the supports is made in the form of parallel rollers, and the other in the form of fixed parallel beams (Authors see foliage of the USSR No. 1331755, IPC B65G 47/00, 1987).

The disadvantage of the tilter is the inability to use it for unloading products of low strength from containers.

The task to which the invention is directed is the development of such a design that would ensure automatic, without damage, unloading of products of low strength from containers and transferring them for further transportation to the transport system.

This is achieved by the fact that, in contrast to the known tilter design, the proposed design is equipped with a rotary mechanism from the drive, consisting of forks on which the container is mounted, and guides mounted on forks, along which the carriage with a cover having rotary blades can be fixed with the possibility of their fixation in the closed position, and the space inside the movable cover is divided into several volumes by partitions covered with elastic material. Partitions installed inside the movable lid divide the space formed by the lid and container into compartments.

The device includes a rotary mechanism 1 mounted on a shaft on a frame 2. A gear 3 is also rigidly fixed to the shaft, which is connected via a chain to the drive sprocket 4 (Fig. 1). The swivel mechanism has the ability to rotate 180 ° from the lower position to the upper and vice versa. This mechanism (figure 2) consists of forks 5, on which there are mounted guides along which the carriage with a movable cover 6 moves. The carriage with a cover is moved with the help of a pneumatic cylinder 7. The rotary blades 8 are mounted on the cover, which are locked through the lever 9 in the closed the position of the pneumatic cylinder 10. Partitions 11, covered with elastic material and installed inside the movable lid, divide the space formed by the lid and container into compartments.

Figure 1 shows the device, a General view;

figure 2 - diagram of the device;

figure 3 - scheme of the proposed device.

The device operates as follows.

The rotary mechanism 1 is in the initial position shown in figure 1.

First step. Technological packaging with products is placed on the forks of this rotary mechanism. The movable lid 6 is lowered and rigidly fixes this container. In this case, the space inside the lid is divided into several small volumes by partitions 11 covered with elastic material.

Second step. The swivel mechanism rotates 180 ° to the upper position. Products are poured onto the bottom of the movable cover. Since partitions covered with elastic material and installed inside the movable lid divide the space formed by the lid and the container into compartments, the products do not have time to accelerate to a considerable speed when being poured from the bottom of the container to the lid and are not damaged.

Third step. Under the action of the pneumatic cylinder 7, the movable cover is lowered to the lower position.

Fourth step. Under the action of the pneumatic cylinder 10, the fixation of the blades is removed, which, under the weight of the products, are ajar.

Fifth step. Under the action of the pneumatic cylinder 7, the movable cover rises up. Products remain on the discharge surface. In the upper position of the cover, the pneumatic cylinder 10 rotates the blades in the closed position and fixes them.

Sixth step. The rotary device returns to its original lower position, the movable lid is lifted, making it possible to replace empty containers.

Claims (2)

1. A device for unloading products of low strength from containers, including a frame and a drive, characterized in that it is equipped with a rotary mechanism from the drive, consisting of forks on which the container is mounted, and guides mounted on forks, along which the carriage with a lid, having rotary blades with the possibility of their fixation in the closed position, and the space inside the movable cover is divided into several volumes by partitions covered with elastic material. 2. The device according to claim 1, characterized in that the partitions installed inside the movable cover of the partition divide the space formed by the cover and container into compartments.
