Definitions
- the present invention relates to a cleaning device for a machine for positioning wicks ("fiber placement") of preimpregnated carbon fibers and in particular to a device for filtering, extracting and removing the surface excess of fiber and resin from said wicks .
- wick positioning machines are well known as those manufactured by Cincinatti Milacron Inc. In these machines, a plurality of pre-impregnated resin fiber wicks from various rolls are conducted in the form of a band of wicks to an application head from which they are applied on a mold for the shaping of pieces with the desired shapes.
- Wick positioning machines are particularly used for the placement of layers of composite material on a mold with curved shapes, the wicks being very thin to be able to adapt them to the desired curved shapes.
- the material of the wicks is the prepreg, a mixture of fibrous reinforcement and polymeric matrix that is sticky in nature.
- the wicks which can have a width of, for example, 3.2 mm, circulate through the wick positioning machine in the form of a band of a plurality of wicks, for example 32 wicks, to the head of application in which the cutting, gripping and advancing systems of the material are integrated so that the wrapping of the piece is carried out in accordance with the previously established patterns.
- the band of wicks passes through very narrow guides and channels for each wick for the control of its displacements, which causes some degree of fluff, dry fibers, excess resin and surface dirt to be created by the simple friction of the material as it passes through said guide channels.
- said defects may be originally present in the wicks themselves since it is difficult to avoid them completely during their manufacture, especially in the case of very narrow wicks that require high precision in the impregnation and cutting operations.
- the objective of the present invention is to provide a satisfactory solution to the problem mentioned.
- the present invention provides a cleaning device for use in a pre-impregnated carbon fiber wick positioning machine that includes at least one guiding roller of a wick band up to an application head. That device comprises two filter elements arranged so that the band of wicks that are supported by two plates joined with adjustable means of tightening said filter elements and fastening / separating means to / from said machine circulates between them.
- the present invention provides a wick positioning machine with at least one cleaning device with the indicated characteristics that, preferably, is located at the exit of a guide roller.
- An important feature of the present invention is that the cleaning device must be used so that the filtering of the wick band is carried out before its entry into the application head and that eliminates excess lint, dry fibers and resin from the band to minimize the maintenance needs of the application head of the machine.
- the device can have a material evacuation element (dry fibers and resins) accumulated in the filter elements by means of vacuum, aspiration, etc., so that the wicks do not drag this material inside the head.
- a material evacuation element dry fibers and resins
- Figures 1a and 1b are schematic views of the cleaning device object of the present invention, before and after being applied to the wick band, respectively.
- Figure 2 is a schematic view of one of the filter elements of the cleaning device with individual guide channels for the wicks of the band, in order to prevent them from coming together, and therefore sticking the wicks to each other. - TO -
- Figures 3a and 3b show views of the cleaning device object of the present invention located in a wick positioning machine at the exit of a guide roller.
- the cleaning device 5 object of the present invention comprises two filter elements 11, 13 supported by two plates 15, 17 joined with adjustable clamping means 29 of said filter elements 11, 13 for application to the wick band 21 that circulates through the wick positioning machine before reaching the application head 25 which places the required layers 31 of material on a mold 33.
- Said plates 15, 17 also have fastening means (not shown). ) to the fiber positioning machine.
- the band 21 of wicks passes between the filter elements 11, 13 that collect the excess resin and fibers.
- the device 5 can include evacuation means 35 of said excess material, such as vacuum or aspiration systems, so as to avoid the possibility of risk that said excess material can subsequently adhere to the wick band 21.
- one of the filter elements 11, 13 has its inner face configured with guide channels 41 for each wick 43 of the band 21 so as to avoid interference between the wicks 43.
- the means for holding the device and joining the plates 15, 17 are designed so that the device 5 is easily adjustable to the wick band 21 and removable from the wick positioning machine to be able to change the filter elements 11, 13 with certain frequency since said evacuation systems cannot prevent the presence in the filter elements 11, 13 of a certain level of resin and adhered fibers.
- the most important requirements that device 5 must meet are the following:
- the filter elements 11, 13 must be made of a non-contaminating material of the pre-impregnated carbon fiber material that constitutes the band 21 of wicks. In addition, it must be ensured that there is no transfer of material from the filter elements 11, 13 to the wicks of prepreg. In a preferred embodiment they are made with cellular polyethylene foam.
- the function of the filter elements 11, 13 must be limited to the removal of the surface excess of fibers and resins, without affecting the material that constitutes the core of the wicks 43.
- Figures 3a and 3b show a cleaning device 5 according to the present invention applied to the wick band 21 at the exit of a guide roller 47 of a wick positioning machine.
- the present invention comprises the use of one or more cleaning devices 5 in a wick positioning machine in appropriate places, according to the specific configuration of each machine.
