TIMING BELT, AIRTIGHT STRUCTURE FOR SUCTION CONVEYOR AND BAG FILLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/040178
Kind Code:
A1
Abstract:
Disclosed are a bag filling device, an airtight structure for a suction conveyor and a timing belt which enable goods to be successfully sucked in and contribute to the reduction in size of suction conveyor belts. A timing belt (1) is equipped with a plurality of teeth (9) which are arranged in a line in the lengthwise direction of a belt (3), wherein through-holes (7) pierce the belt between the edge sections (5) on both sides of the widthwise direction of the belt. The teeth (9) are arranged further towards the inside, in the widthwise direction of the belt, than the edge sections (5) of the belt. The airtight structure (11) for a suction conveyor is provided with: the timing belt (1); a bottom surfacing (15), which supports the teeth (9) on the timing belt (1) so that they can slide in the lengthwise direction and wherein an air-path (13) for channelling negative pressure through the through-holes (7) is formed; and two airtight liners (17) which are in sliding contact with the respective edge sections (5) on both sides of the belt (3).
