Conveying line limiting device matched with an elevator in use and conveying line using device

Abstract

The invention discloses a conveying line limiting device matched with an elevator in use and a conveying line using the device. The conveying line limiting device comprises a goods blocking part which is hinged to swing up and down. The goods blocking part has a blocking position used for blocking goods and a releasing position for removing blocking in the swinging stroke. The goods blocking part is provided with an ejection transmission part or pressing transmission part which is overhung, is used for moving up and down relatively to the goods blocking part and is in transmission fit with a driving end to drive the goods blocking part to swing to the releasing position when a butting end of the elevator and a butting end of the conveying line are butted in place. A counter weight or return spring used for applying acting force to the goods blocking part to allow the same to swing to the blocking position is connected on the goods blocking part in a transmission manner. When the elevator and the conveying line are not butted in place, the counter weight or return spring can drive the goods blocking part to move to the blocking position to realize limiting, when the elevator and the conveying line are butted in place, the goods blocking part swing to the release position to ensure goods to pass through smoothly, and the conveying line limiting device is simple and compact in structure and reliable in working.

Description

technical field [0001] The invention relates to a conveying line limiting device used in conjunction with an elevator and a conveying line using the device. Background technique [0002] The conveyor line is a widely used article conveying device, such as the ground roller conveyor line. Many ground roller conveyor lines need to transport objects across workshops. In order to avoid blocking the road between the two workshops, the ground between the two workshops The roller table often needs to be partially installed underground, and the objects to be transported are conveyed up and down by elevators. However, sometimes due to wrong operation, signal abnormality, etc., the ground roller on the upper conveying line does not stop completely after the elevator falls, or the ground roller on the elevator does not stop completely when the elevator has not been lifted in place, or the goods are not completely stopped due to inertia. Or its own gravity on the conveyor line may caus...

Problems solved by technology

However, the limiting device in the prior art cannot be used in conjunction with the elevator, and cannot limit the position of the items at the corresponding butt end of the conveyor line of the elevator.
