Definitions

  • the invention relates to a device for producing angled bristles on bristle carriers, such as brushes, brooms and the like.
  • a method and a device for producing a brush seal for sealing against rotating or moving components are known, wherein a deformation unit is arranged in the device, which has a slope that corresponds to the slope of the bristle part to be bent, and then the inclined sloping area is followed by a flat area.
  • the bristles are brought to a temperature by means of a heater, which is necessary for performing the recrystallization annealing of the bristles.
  • the bristles are then cooled so that the inclination angle remains constant.
  • the resulting semi-finished brush is then reshaped so that it receives the desired sealing contour.
  • DE 3506231 C2 discloses a method for producing roller brushes which have a cylindrical carrier body, to which bristles are attached along strip-shaped regions and protrude from the outer surface of the carrier body.
  • a device is arranged on the lateral surface of the carrier body, which has an abutment that is shaped to match the strip-shaped regions of the bristles. This abutment has a lower height than the bristles protruding from the carrier body.
  • the carrier body is rotated relative to the device about its central axis and during this rotation the bristles are pressed in their lower region against the abutment, while their upper end region over the Survive abutments. In this position, the bending process takes place, in which the bristles rest against the abutment, the front end region of the bristles being bent around the abutment by means of a bending device.
  • the object of the invention is to develop a device for producing angled bristles on bristle carriers, in which the bristles are angled by a plurality of bristle carriers.
  • the object is achieved in that the bristles are plastic bristles that are heated up to the thermoplastic region in a container, the bristle carriers being able to be placed on a bristle carrier receptacle of a transport device, and a deformation unit is arranged in the container that has a bevel that is the bevel corresponds to the bristle part to be angled, and has a shape stabilization area following the bevel, the bristle carriers with the plastic bristles heated in the container stroking the bevel of the deformation unit, and these being angled at the level of the deformation unit and then passing through the shape stabilization area which the angled plastic bristles pass through the resulting shape holds, and a cooling and drying unit and a receiving and removing device for the bristle carrier are arranged in the container.
  • ne schematic representation of a device ne bristle holder receptacle, ne schematic representation of a housed device, ne side view of a deformation unit and top view, ne side view of a deformation unit with rods and
  • FIG. 7 shows a bristle holder receptacle with hollow bodies
  • FIG. 8 shows the bristle holder receptacle with clamping jaw slide
  • FIG. 9 shows the bristle holder receptacle with clamping levers
  • FIG. 1 shows a schematic representation of a device for producing angled plastic bristles 1 by means of heated liquid 21.
  • the basic structure of this device consists of a transport device 7, for example an endless conveyor belt 14, which has a bristle holder receptacle 6 in a receiving and removal device 12.
  • the bristle carriers 3 are inserted with the plastic bristles 1 upwards and are guided through a container 5 open at the top by means of the transport unit 7.
  • the container 5 is the liquid 21, which is heated to a temperature which corresponds to the thermoplastic region of the plastic bristles 1.
  • the plastic bristles 1 heated in this way stroke a deformation unit 4 in the container 5 and are thereby brought into the predetermined angled shape.
  • the transport device 7 is guided through a cooling and drying unit 11, where the plastic bristles 1 are cooled in order to maintain their angled shape, and are dried in order to subsequently remove them from the bristle holder receptacle 6 in the receiving and removal device 12.
  • FIG. 2 shows the individual parts of the bristle holder receptacle 6.
  • the bristle holder receptacle 6 consists of a U-shaped base holder 13 which is fastened on the conveyor belt 14 on the back and transversely to the running direction.
  • the two opposite surfaces of the base holder 13 have height-adjustable L-shaped guides 15.
  • an interchangeable slide 16 for receiving the bristle carrier 3 is inserted.
  • guide strips 17 are mounted transversely to the running direction of the conveyor belt 14 in parallel rows and at the same distance from one another. If the bristle carrier 3 is placed on the interchangeable slide 16 and pushed into the bristle holder 13, the plastic bristles 1 line up between the guide strips 17.
  • FIG. 3 shows a schematic representation of a housed device for producing angled plastic bristles 1.
  • the device consists of a container 5, in which a drum 24 is arranged which rotates about its longitudinal axis and which serves for the passage of the bristle carriers 3.
  • the bristle carrier receptacle 6 with the receiving and removal device 12 for the bristle carrier 3 with the plastic bristles 1 to be angled is located on the drum 24.
  • a supply line 28 for hot air 25 from a hot air unit 18 is arranged in the form of a jacket around part of the drum 24.
  • the hot air 25 emerges from openings 22 of the feed line 28 in the Annular space between the drum 24 and the feed line 28 and heats the plastic bristles 1 carried past on the bristle carriers 3. Following the feed line 28, the deformation unit 4 for the heated plastic bristles 1 adjoins the drum 24.
  • the bevel 8 of the deformation unit 4 restricts the annular space between the drum 24 and the deformation unit 4 until the height 10 of the bevel 8 of the deformation unit 4 is sufficient to bend the plastic bristles 1 on the guide bar 17 of the base holder 13 at the required angle ⁇ and the required length ,
  • the slope 8 of the deformation unit 4 is adjoined by a shape-stabilizing region 26, which keeps the angled plastic bristles 1 in the shape formed when the drum 24 passes through, at the drum 24 at a constant distance from the drum 24.
  • the cooling and drying unit 11 connects to the shape stabilization area 26.
  • the bristle carrier 3 then moves in the bristle carrier receptacle 6 by means of the drum 24 back to the receiving and removal device 12.
  • the deformation unit 4 shows the details of the deformation unit 4. It basically consists of an ascending bevel 8, to which the shape stabilization area 26 adjoins.
  • the shape stabilization area 26 is coated for the purpose of a high coefficient of friction.
  • grooves 20 are arranged on the slope 8 in the direction of the slope (see plan view).
  • rods 19 with grooves 20 arranged in the direction of the run-up can be attached to the bevel 8 transversely to the direction of run-up.
  • the bars 20 can be replaced by steps 29 with grooves 20.
  • These deformation units 4 can also be in the container 5 adjustable in height, as shown in FIG. 1.
  • the bristle lengths to be angled in the plastic bristles 1 can thus be set.
  • the guide strips 17 of the bristle holder receptacle 6 are designed as hollow bodies 23.
  • the hollow bodies 23 each have opposite openings 27 along their length.
  • supplied hot air 25 or liquid 21 emerges from the deformation area 2 of the plastic bristles 1 and heats this point up to the thermoplastic area in order to be subsequently angled in the deformation unit 4.
  • FIG. 8 shows the bristle holder receptacle 6 with a clamping claw slide 30.
  • the bristle holder receptacle 6 consists of the U-shaped base holder 13, which is fastened transversely to the transport direction on the transport device 7, for example on the conveyor belt 14.
  • the two legs of the base holder 13 have the L-shaped guides 15 on the inside.
  • a clamping jaw slide 30 is arranged such that it can be locked, the width of the clamping jaw slide 30 being adaptable to the width of a bristle carrier 3.
  • the bristle carrier 3 is clamped on the clamping jaw slide 30 by the bevel 8 at the two upper ends of the clamping jaw slide 30.
  • FIG. 9 shows the bristle holder receptacle with clamping levers.
  • the bristle carrier receptacle 6 consists of the U-shaped base holder 13, which is fastened transversely to the transport direction on the transport device 7, for example on the conveyor belt 14.
  • the two legs of the base holder 13 have the L-shaped guides 15 on the inside.
  • a bristle carrier clamping plate 33 is placed on the guides 15, a clamping lever 32 being articulated on each side of the L-shaped guides 15 on the two sides of the bristle carrier plate 33.
  • the bristle holders 3 are thus lockable and detachably fastened in the bristle holder receptacle 6.
  • the clamping claw slide 30 and the clamping lever 32 are connected to actuable control elements via switching linkages 31 for opening and closing.
