Definitions

  • the invention relates to a device for applying fleece, in particular mineral wool fleece, to a support belt, with a feed belt for the fleece, with two pendulum-like, essentially parallel conveyor belts between which the fleece is transported and which is in a plane perpendicular to the support belt and swing perpendicular to the direction of movement of the support belt between two reversal points, the speed of the support belt being lower than the dispensing speed of the fleece, so that it comes to rest on the support belt in at least partially overlapping layers.
  • the fleece is always discharged at a constant speed between the conveyor belts, so that an uneven layer thickness of the fleece applied to the support belt, also called secondary fleece, transversely to the direction of movement of the support belt is the result.
  • a linear drive is provided for the conveyor belts, which can move the conveyor belts back and forth between the variably definable reversal points with variable speed.
  • the linear drive can be controlled so that when the width of the secondary fleece to be produced or the fleece plate is fixed, this information is converted into the pendulum motion. It is also possible to vary the speed in such a way that, for example, in one area of the support belt, the conveyor belts are continuously guided over it at a low speed, and therefore in a neighboring area at a higher speed. In this way, a nonwoven plate can be produced which initially has a greater, then a lower, density transversely to the direction of movement of the support belt.
  • the fleece plate has a greater layer thickness, the slower the speed of the drive and thus the pendulum movement in the corresponding area.
  • a limit switch which determines the maximum deflection of the conveyor belts, can advantageously be arranged on each side of the support belt. These represent an emergency circuit that prevents material from being placed beyond the actual support belt.
  • a double-sided toothed belt as the linear drive, which is arranged perpendicularly to the direction of movement of the support belt, the conveyor belts being fixed to a common carriage which is in engagement with the drive. This means that the movement of the conveyor belts is maintained at exactly one defined level.
  • the carriage can advantageously be provided on its underside with at least one roller, which closes contact with at least one of the limit switches.
  • an oven which is arranged essentially above the support belt and has a height adjustment on each side of the support belt, which can be adjusted independently of one another.
  • the oven can thus be adapted directly to the profile of the non-woven sheet and thus ensure optimal curing.
  • a pendulum 1 consists of a substantially horizontally arranged feed belt 10 for nonwoven material, which transports it to two conveyor belts 11, 12 which are arranged essentially parallel to one another and transport the fleece fed to them between them.
  • the conveyor belts 11, 12 are suspended in such a way that a pendulum-like movement is possible, which is coordinated in such a way that there is always a uniform conveying of nonwoven.
  • the output ends 13, 14, of the conveyor belts 11, 12 are located above a support belt 2, which moves perpendicular to the pendulum plane of the pendulum 1 at a substantially constant speed.
  • the conveyor belts 11, 12 are fixed together on a carriage 15 in their lower region, but above the discharge ends 13, 14.
  • This carriage 15 is provided with a drive sleeve 16 which engages with two toothed belts 43 belonging to a linear drive 4.
  • the toothed belts 43 are also arranged in the pendulum plane, that is to say perpendicular to the direction of movement of the support belt 2.
  • the carriage has two pairs of rollers 17, 18 at its front and rear ends, which rest on a support surface 45.
  • This contact surface 45 supports a bearing 44 and a gear 42 at the same time, the drive rod 43 being fixed between them.
  • a drive motor 41 is provided above the gear 42, so that it is possible to set the drive rod 43 in rotation, so that, via the engagement with the drive sleeve 16, the conveyor belts 11, 12, depending on the direction of rotation of the motor 41 and thus the drive rod 43, can be moved back and forth over the support belt 2.
  • the device is monitored by a control unit 3.
  • the fuse switch-off of two limit switches 46, 47 which are provided on the support surface 45 on each side of the support band 2 and each determine the maximum end position of the pendulum 1. An alarm can be given or an emergency stop can be triggered if the pendulum moves beyond these maximum end positions.
  • the pairs of rollers 17, 18 serve as sensors, so that, for example, a signal is given when the pair of rollers 17 touches the limit switch 46 and thus closes, or else the pair of rollers 18 cooperates with the limit switch 47 in the same way.
  • the contact between limit switch 46 and roller pair 17 can also trigger an alarm, while the emergency stop is only triggered when roller pair 18 contacts this limit switch 46.
  • a corresponding control can be provided in connection with the limit switch 47.
  • control unit 3 receives further information from a reference switch 21, which is assigned to the support belt 2.
  • This reference switch 21 sets the zero point of the support tape 2 fixed.
  • the contact point of the reference switch 21 is in turn located on the support surface 45 and can be closed via a contact provided on the slide 15, which can also exist in one of the two pairs of rollers 17, 18.
  • a frequency converter 30 receives information about the speed of the drive motor 41 via a data line 31 and transmits this to the control unit 3 via a data line 32.
  • the speed of the drive motor 41 can in turn be influenced via the motor cable 32 via the same data line 33.
  • An operating device 29 is connected to a host computer 35 via a data line 38.
  • the pendulum width can be entered via the control unit, i.e. the desired width of the non-woven sheet to be produced. This is usually 1800 to 2200 mm.
  • the master computer uses this to calculate the value for the pendulum movement to the right and to the left and transfers this data to the control unit 3 via the data line 34.
  • the master computer 35 also triggers the start of the pendulum 1 and monitors the data transfer on the line 34 and the state of the Overall system.
  • an output area 36 is provided which gives data from the host computer to the control device 3, for example the command to start the pendulum 1, and an input area 37 which receives data from the control device, for example about the current value of the pendulum movement.
  • the operator can now generate a desired plate quality via the operating device 39.
  • the control unit 3 then operates the drive motor 41 as required and simultaneously monitors the correct operation by information about its speed via the data line 31, the frequency converter 30 and the data line 33.
  • the drive motor 41 actuates the drive rod 43 in accordance with the signals received. which via their engagement with the drive sleeve 16 guide the conveyor belts 11, 12 fastened to the carriage 15 over the support belt 2.
  • Fig. 2 shows a cross section through an oven to be used with the device according to the invention.
  • This has an elongated housing 60, in which an endless conveyor belt, hereinafter referred to as the upper conveyor belt 70, is accommodated.
  • the upper conveyor belt 70 is guided by means of deflection rollers fixed to the side walls of the housing 60.
  • the top wall 61 and the side walls 62, 63 are thermally insulated, a further thermal insulation is arranged below the upper run 71 of the upper conveyor belt 70 and closes it off from the rest of the housing space in the region of the upper run.
  • a lower conveyor belt 75 is provided running parallel to the upper conveyor belt 70, the upper run 76 of which is opposite the lower run 72 of the upper conveyor belt 70.
  • the lower conveyor belt 75 is likewise enclosed in a housing 65 and guided by means of deflection rollers, the bottom wall 66 and side walls 67, 68 of the housing in turn being thermally insulated and further thermal insulation 69 being provided above the lower run 77 of the conveyor belt 75. Both conveyor belts 70, 75 can be heated.
  • the lower housing 65 is displaceable in the vertical direction with respect to the upper housing 60, which is brought about by hydraulic devices 80, 81 which are fixed to the side walls 63, 68 and 62, 67, respectively. These hydraulic devices 80, 81 can be operated independently of one another.
  • the fleece to be cured is fed to the furnace in such a way that it is guided between the upper side of the upper run 76 of the lower conveyor belt 75 and the lower side of the lower run 72 of the upper conveyor belt 70 and is heated at the same time.
  • the distance between the runs 72, 76 can be adjusted by appropriate control of the hydraulic devices 80, 81, this adjustment also being able to be carried out in accordance with control signals which are predetermined by the desired profile of the plate.
  • the heating effect of the furnace is thus optimally adapted to the profile of the plates.
