Arrangement for covering a chip transport box |
| abstract |
Arrangement for covering a chip transport box including a cover which is adapted to be rolled up on and unrolled from a shaft and a swinging arm provided at each of two opposite walls of the chip transport box whereby one end of the swinging arm is pivotally journalled at the respective wall and at least one piston and cylinder unit connected to at least one of the swinging arms and to said wall for swinging the swinging arms and for extending the cover across the chip transport box from one side thereof to the other. The swinging arms do in their other ends rotatably carry the shaft for swinging the same across the chip transport box when the swinging arms are actuated by the piston and cylinder unit, and a pull-belt has one end attached to the chip transport box and its other end is adapted to be rolled up on and unrolled from the shaft in a reversed mode relative to the rolling up of and the unrolling of the cover in order to bring about the movement of the shaft which causes the cover to be rolled up on and unrolled from the shaft when the swinging arms are operated. The cover is in one end thereof rigidly attached to the shaft and in its other end it is directly or indirectly fastened to one of the walls of the chip transport box and the cover includes resilient members which in the final stage of the unrolling of the cover are extended and which act with a tensioning force on the cover whereby this is brought to close contact with the upper edges of the chip transport box. |
