Abstract
The invention relates to a device for orienting elements, in particular filter elements (F), for fitting injection-molded parts, in particular pipette tips (P), comprising an accommodating container (1a) for accommodating the filter elements (F) as bulk material, a sieve plate (1), which forms the bottom of the accommodating container and which has bores (11) for accommodating individual filter elements (F), a buffer plate (2), which is arranged under the sieve plate (1) and which has bores (2.1) corresponding to the bores of the buffer plate (2) and which is arranged below the buffer plate in such way that the transfer plate can moved in relation to the buffer plate (2).
Claims15
A method for the alignment of individual elements, in particular filter elements (F), for mounting of injection molded parts, in particular the pipette tips (P), comprising the following steps:
- receiving the filter elements (F) as bulk material in a receptacle container (1a), wherein the bottom of the receptacle container (1a) is formed as a sieve plate (1) with bore holes (1.1) corresponding to the diameter of the filter elements (F),
- performing a rocking motion on the receiving container (1a) for transferring the disordered filter elements (F) into the bore holes (1.1) of the sieve plate (1),
- transferring said filter elements (F) of the sieve plate (1) into bore holes (2.1) of a buffer plate (2),
- making available said filter elements (F) in a predetermined position in the bore holes (2,1) of the buffer plate (2),
- transferring said filter elements (F) of the buffer plate (2) into bore holes (3.1) of a transfer plate (3), and
- transferring the filter elements (F) arranged in groups in the transfer plate (3) to a handling device.
An apparatus for aligning elements, especially filter elements (F), for mounting of injection molded parts, in particular pipette tips (P) comprising
- a receptacle container (1a) for receiving filter elements (F) as bulk material, a bottom of the receptacle container forming a sieve plate (1) with bore holes (1.1) for receiving individual filter elements (F),
- a buffer plate (2) disposed under the sieve plate (1) and having bore holes (2.1) corresponding to the bore holes of the sieve plate (1), and
- a transfer plate (3), which is disposed movable relative to the buffer plate (2), is located below the buffer plate (2) and having bore holes (3.1) corresponding
- to the bore holes of the buffer plate (3).
