SU1386524A1 - Apparatus for emptying soft containers - Google Patents

Abstract

The invention relates to the field of loading and unloading and mo. It can be used when unloading soft disposable containers in construction, food and other industries of the national economy. The purpose of the invention is to increase the reliability of work. The soft container with the bulk material is lowered onto the cutting mechanism located in the housing 1. In this case, the container is cut by knife elements 2 fixed on the conveyor 3 placed in the upper rigid casing 4. The lower hard casing A enters at a right angle into the upper casing through the groove 6. The subsequent cutting of the bottom of the container is carried out by the blade elements 2 of the lower rigid casing 4. Under the influence of the mass of material, the bottom opens and the material is poured out. The pieces of the product are ground in a crusher 7. 5 Il. S (l

unloading and transport and warehousing operations and can be used to mechanize the unloading of disposable soft containers in the construction, food and other sectors of the national economy.

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

FIG. 1 shows a device for unloading soft containers; in fig. 2 is a view A of FIG. one; in fig. 3 - a common knife element; in fig. 4 is a view B in FIG. 3; on - a knife element, a section.

The device includes a housing 1, a mechanism for cutting containers secured therein, including mutually perpendicular knife elements 2.

The mechanism for cutting the containers is made of one above the other in mutually perpendicular vertical planes of the conveyors 3 and the rigid shells 4 enclosing them, while the knife elements 2 are located on the conveyors 3, and in the upper part of each case a knife slot elements 2.

The hard shells 4 are inserted one into the other through the slots 6 at a right angle and are in different horizontal planes. At the same time, in the upper part, the width L of the hard shells 4 is smaller than the width a of the knife elements 2 which protrude above them, and in the lower part of the base with rigid shells more than the width d in which the knife elements are recessed, i.e. these dimensions are related by the following inequality

Thus, the bottom of the container is cut into four pieces and, under the action of the mass of the product, opens and the product falls out.

If the product has an angle of repose of 45-75 or more or, during transportation and storage, it is packed inside the container and turned into

0 into the monolith, the container is lowered and discharged to the neck. At the same time, the knife elements simultaneously cut and the product, which falls out of the container in pieces, is crushed into crushers.

In this case, the emptying part of the container does not touch the lower parts of the knife elements 2, which can lead to grinding or tearing of individual

0 pieces of container material, since the lower parts (idle branches) of knife elements 2 are submerged: in rigid shells 4. At the same time, the cut parts of the bottom of the container do not touch the hammers

The Qra of the body 1, the unstitched parts of the container also do not touch the lower parts of the knife elements 2.

The use of the invention in the national economy in the unloading of soft containers with bulk material

Formula and goiter R e e N and b a d c. Crusher 7 is located from the knife elements at a distance H, which is greater than the height of the expanded container, i.e. H L + K (where L is the height of the container; K is the height of 1/4 of the cut bottom of the container). The blade elements 2 are equipped with an electric drive 8, The device works as follows. The container is lowered into the housing .1 and its bottom is first cut into two parts by a moving, top-down knife element 2. Then, when the container is further lowered, its bottom is cut into two more parts by the knife element 2 below. A device for unloading soft containers, comprising a housing, a mechanism for cutting containers therein, including mutually perpendicular knife elements, characterized in that, in order to increase reliability of operation, the mechanism for cutting containers consists one above the other in mutually perpendicular the vertical planes of the conveyors and the rigid shells encompassing them, at that time the knife elements are located on the conveyors, and in the upper part of each case there is a slot above the conveyor branch for knife elements. & ud / i tel at  one 2 Fig.Z
