Description

  The present invention relates to a bag-breaking apparatus for taking out waste stored in a flexible container bag (hereinafter simply referred to as "flexure") out of the bag.

  FIBC is used to transport and store radioactive waste, general waste, industrial waste, etc. When removing stored items, the contents of the container are removed by breaking the bag. In particular, when decontaminating land contaminated with radioactive materials in recent years, contaminated soil, plants, trees and litter are temporarily stored in a container, transported to a predetermined intermediate storage facility, and the contents are removed at the disposal site. To break the bag.

  As a device for realizing the above-mentioned bag breakage, in Patent Document 1, a ring-shaped flexible substrate is provided at the upper portion of the hopper, and a device provided with a rotating body having a cutting blade protruding upward on the outer periphery of the flexible substrate is disclosed. It is disclosed.

  Further, in Patent Document 2, a laser cutting unit which forms an opening including the center on the bottom surface of the container on the flexible container mounting plate, provides an upper and lower movable plate in the opening, and moves along the outer peripheral edge of the opening. Discloses a device for laser cutting the bottom of the flexible container on the flexible container mounting table and opening the opening by moving the movable plate downward to discharge the contents of the flexible container from the opening.

  Further, in Patent Document 3, a plurality of movable floors are provided, and a predetermined gap (a linear cutting guide groove) is formed in the closed state of the movable floors, and the bottom of the FIBC on the movable floor is cut and cut by a cutting means. There is disclosed a bag-breaking apparatus which allows the contents of the flexible container to fall naturally with the movable floor opened.

  The conventional bag-breaking apparatus basically adopts a configuration in which the bottom surface of the flexible container is cut from below, so the contents fall down on the cutting mechanism when the contents fall after cutting, so the cutting mechanism Parts and structures are required for protection. For example, a cutting blade rotating body (Patent Document 1) requires a structure for preventing entry of stored items between the fixed flexible substrate and the moving table (Patent Document 2) or movable floor (Patent Document 3). In this case, the evacuation mechanism for the cutting mechanism is required before the content of the container is discharged (before the movement of the floor), and the device becomes complicated.

  Also, since the bottom of the flexible container in the content storage state is in a curved state, and the boundary between the bottom of the flexible container and the peripheral surface is in a curved state even if placed on a flat mounting surface, the flexible container is cut from below the bottom However, since the peripheral surface of the flexible container is not reached, there is a risk that contents may exist between the cut bottom surface and the peripheral surface.

  Therefore, the present invention proposes a flexible container bag tearing apparatus which has a simple cutting mechanism and reliably discharges the contents of the flexible container.

  The apparatus for tearing a flexible container bag (Flecon) according to claim 1 of the present invention rotatably incorporates a cylinder having a predetermined volume into an appropriate base frame, and a rotational drive unit for rotating the cylinder. A bag supporting part not attached to the cylinder opening and not closing the cylinder opening at an appropriate position below the cylinder opening is branched from the base frame and provided at the outer peripheral position of the cylinder opening to be able to advance downward inside the opening. A cutting mechanism is disposed.

  According to the third aspect of the present invention, the apparatus for tearing a flexible container according to the present invention has a support arm projecting toward the center of the base frame at an appropriate height of the support and is rotatable on the upper surface of the intersection of the support arms. The bottom plate of the container housed in the cylinder is placed on the bag holder, and the rotation of the container with the rotation of the cylinder can be smoothly performed. And the space between the support arms becomes the drop space of the contents.

  According to the fourth aspect of the present invention, the apparatus for tearing off a bag according to the fourth aspect of the present invention has the cutting mechanism section constituted by a rotary blade having a drive motor, and an existing electric tool can be adopted. It is possible to use inexpensive existing parts even for the consumption of

  Further, the apparatus for tear-off a container of a flexible container according to claim 5 of the present invention has a discharge unit to the outside of the base frame corresponding to the size of the cylindrical opening, for example, a discharge conveyor, a discharge slope, etc. The contents fall out of the container and are immediately discharged out of the base frame, and the next bag-breaking operation is in a standby state.
