Problems solved by technology

The disadvantage of this device is that it requires a considerable amount of space, which is caused (among other factors) by the blowing direction of the spray source (air nozzle) in the area below the opening roller
Furthermore, it is inconvenient for the injection source and valve to be freely located in the waste collection area, which can lead to substantial interference, interruptions, etc. to the operation
Another disadvantage is that the air nozzles with magnetic valves are arranged separately across the width of the roll

Embodiment Construction

[0027] Referring to Figure 1, in a device for detecting and separating foreign matter, for example in the Trützschler foreign matter separator SECUROMAT SP-F2, the upper inlet opening of the supply tank 1 is connected with the equipment for the pneumatic supply of fiber-air flow A, which consists of Fibrous material conveying fan (not shown), stationary air permeable surface 2 for separating (spraying) fibrous material B from air C by means of air extraction, and air flow guiding means 3 with movable elements; laterally on air permeable surface 2 The fibrous material in the airflow is repeatedly guided back and forth, and after the impact, the fibrous material basically falls from the air-permeable surface 2 due to gravity and enters the feed trough 1 downward. The slow rolls 4a, 4b have a double function: they act as delivery rolls for removing the fibrous material B from the feed chute 1 and at the same time as feed rolls for feeding the fibrous material B to the high speed o...

Abstract

In an apparatus in spinning preparation for separating foreign objects at conveying equipment for fibre material, at least one separation device is associated with the conveying equipment. The separation device comprises an arrangement for producing a blast of air that flows in the direction onto the conveying equipment and generates an air flow that detaches the foreign objects from the conveyed fibres and carries them away. The arrangement comprises a plurality of blast nozzles arranged across the width of the conveying equipment and connected to a compressed air pipe and to valves. To reduce the proportion of good fibres in the waste in a simple manner, and to allow a more selective action of the blast air current, a bar member for mounting the blast nozzles is present and the nozzles are integrated in the bar member.

Description

technical field [0001] The invention relates to a device for separating foreign matter at a conveying device for fibrous material (such as cotton, synthetic fibers, etc.) Equipment for generating a jet flow onto the conveying device, which generates an air flow that separates foreign objects from the conveying device and entrains them, the device comprising multiple nozzles. Background technique [0002] It is known from WO 89 / 01832 A to arrange a plurality of nozzles across the width at the outer wall of a pneumatic conveying duct through which the fibers and the air stream flow. The nozzles are freely arranged side by side and spaced apart from each other. For a 160mm wide delivery pipe, 8 nozzles will be sufficient. In order to release high-speed jet gas, a gas valve with a response time of 10 milliseconds or less is connected to the nozzle. In practice, valved nozzles are fixed to the outer wall of the delivery pipe. These side-by-side valves require a lot of space....
