Definitions

the present invention relates to a cleaning device for a textile machine according to the preamble of claim 1.
a device of this type is known from US-A-4,572,745 without disclosing details of the suction duct and the blowing nozzle.
a cleaning device for a textile machine having a suction duct ( Figure 9,10) for sucking fly waste from the floor and a blowing nozzle that blows air and blows the fly waste settled on the floor towards that suction duct are arranged.
the shape of a fly waste suction opening (8a) of a suction duct (8) is formed into a wide rectangular shape.
the aforementioned blowing nozzle blows air from directly above the floor or at an angle and blows the fly waste settled on the floor to the suction nozzle.
a cleaning device formed in accordance with the invention has several advantages.
An air current is caused between the guide member and the floor in a direction that draws fly waste on the floor towards the area directly below the suction opening. This effect may be enhanced by bending the tip of the blowing nozzle parallel to the surface of the floor.
a stopper member may be attached to the guide member to prevent contact between the guide member and the floor. Due to this, when the suction duct carries out collection of fly waste on the floor, there is no suction of the guide member lower surface onto the floor by the flow of air generated towards the suction opening from the floor.
Figure 1 is a side view showing a summary of the layout of an embodiment of the cleaning device of the present invention and a winder comprising a plurality of winding units.

One cleaning device (101) is provided with two suction ducts (103A,103B) and two blowing ducts (104A,104B).
suction duct (103A) and the blowing duct (104A) are placed one side of the winding unit (U) opposite the blowing duct (104B) and the suction duct (103B) respectively.
suction duct (103A,103B) and each blowing duct (104A,104B) are attached to both sides of the cleaning device main body (101a) in the movement direction.
FIG 12 is an expanded sectional view of another embodiment of the end part of the suction duct of the cleaning device of the present invention.
An attachment (103f) for a suction duct comprising a suction opening (103a) and a guide member (103b) which may be attached to or removed from the end of the wall of the bracket forming the suction opening 103a are arranged on the end of the suction duct (103).
the guide member (103b) is attached level with the floor (F) so an air current is generated from the suction ducts (103A,103B) in the suction direction along the surface of the floor (F) near the suction opening (103b) when the air supply part is operated.
the suction opening (103a) is round and the guide member (103b) is a round plate arranged concentric with the suction opening (103a). Furthermore, the duct main body of the suction duct (103) comprises an extendable material and can extend in the vertical direction (direction of arrow (C) in Figure 12). The suction duct attachment (103f) is detachable from the suction duct (103).
a number of of stopper members (103d) are arranged at a number of places on the bottom surface (103c) of the guide member (103b).
the stopper member (103d) is a projecting semi-sphere and is continuous with the bottom surface (103c) of the guide member (103b). Under normal conditions, suction of dust such as fly waste is carried out with there being no contact between the surface of the floor (F) and the tip of the stopper member (103d).
Figure 13 is an exploded perspective view of the end part of the suction duct of Figure 12.
a bracket (109) is a hollow cylinder and is divided into a plurality (in the present embodiment: 2) of members (107,107) along the axial direction. Rim stoppers (107a) are arranged on each of the edges of the sides comprising the suction opening (103a). Also, a groove (108a) being a concave connector is arranged on one of the divided surfaces and a ridge (108b) being a convex connection part which connects with the groove (108a) is arranged on the other side (Refer to Figure 14). The groove (108a) and the ridge (108b) are formed along each of the respective dividing surfaces (107b) in the axial direction.
a hole (103e) in which the bracket (109) is inserted and a concave stopper (111) which fits with the aforementioned rim stopper (107a) are arranged on the center part of the guide member (103b).
the diameter of this hole (103) is the ths same as the diameter of the outer circumference wall of the bracket (109). It should be noted that each of the members (107,107) and guide member (103b) are constructed of synthetic polymer in order to maintain product lightness.
the operator assembles the bracket (109) by fitting together the groove (108a) and the ridge (108b) of one member (107) with the ridge (108b) and the groove (108a) of the other member. Then the operator inserts it in the guide member (103b) from the side on which the convex stopper (107a) is not arranged and pushes the guide member (103b) against the bracket (109) until the convex stopper (111) of the guide member (103b) connects with the rim stopper (107a).
the attachment (103f) assembled as described above is inserted into the end opening of the main body of the suction duct (103) by the end of the bracket (109). Afterwards, the stopper ring (110) is attached to the main body of the suction duct (103) at the inserted part and by tightening the stopper ring (110) , the attachment (103f) is fixed to the main body of the suction duct (103).
the groove (108a) is arranged on one dividing surface (107b) of the member (107) and the ridge (108b) is arranged on the other dividing surface (107b) but the groove (108a) may be arranged on both dividing surfaces (107b) of one member (107) and the ridge (108b) may be arranged on both dividing surfaces (107b) of the other member (107).
alternate grooves (108a) and ridges (108b) may be arranged in the longitudinal direction of the dividing surface (107b) of one of the members (107) and ridges (108b) and grooves (108a) corresponding to the aforementioned grooves (108a) and ridges (108b) may be arranged alternately on the other dividing surface (107b) of the member (107) opposite the aforementioned dividing surface (107b) (see Figure 15). Due to the construction of grooves (108a) and ridges (108b) as in Figure 15, there is no slippage between the assembled members (107,107) in the axial direction of the bracket (109). Furthermore, the stopper member may be arranged in a position other than the bottom surface of the guide member, for example projecting from a cylindrical bracket.
a blowing nozzle is attached to the end of the blowing duct of the cleaning device.
