As (A) of Fig. 3 with (B), the accommodating groove 12a that is used to take in electronic unit W is formed at the outer peripheral edges of turntable 12 in the mode of leaving the angle corresponding with the indexing transfer of turntable in a circumferential direction mutually, and accommodating groove is the pass through openings shape that has connected turntable.For example, if the indexing transfer of turntable 12 is 7.5 °, then leave 7.5 ° and make 48 accommodating groove 12a be formed at the outer peripheral edges of turntable 12 in a circumferential direction mutually.In an embodiment, the profile of electronic unit W is a rectangle, and accommodating groove 12a is bigger slightly than the overall dimension of electronic unit, is the pass through openings that its length direction is positioned at the rectangular shape of radial direction.
In the accommodating groove 12a of pass through openings shape, the electronic unit W that is taken in might come off, and therefore, the supporting disk 13 that has carried turntable 12 rotationally forms the diameter roughly the same with turntable so that its upper surface under cover accommodating groove 12a.Therefore, the electronic unit in the accommodating groove 12a can not come off from accommodating groove, but is accompanied by the indexing transfer of turntable, transmits in the enterprising line slip of supporting disk.
In addition, in the present invention, carry out the exchange of electronic unit in vertical direction, therefore in supply station A, the counter-rotating station C of the exchange of carrying out electronic unit, as described later, cut the part of supporting disk 13 and will raise member 20, counter-rotating platform 24 be configured in turntable 12 around, thereby can realize the exchange of the electronic unit on the vertical direction.
In the linear loader 14b of feed appliance, the path 14b1 that is used to supply with the cardinal principle U word cross sectional shape of electronic unit W be formed up to the accommodating groove 12a (12a1) that is positioned at supply station A under.In addition, stopper sheet 14b2 creep into to cross the accommodating groove 12a1 that is positioned at supply station A from the front end of linear loader 14b the turntable outer peripheral edges below mode extend, the stopper end 14b2 ' of stopper sheet is at the end of path 14b1, be positioned at accommodating groove 12a1 under.
From Fig. 4 (A) as can be known, dead ahead at the stopper end 14b2 ' of stopper sheet, the path 14b1 of linear loader is drawn out of at the end under accommodating groove 12a1, dispose under the path that is drawn out of the end of at and raise member 20, in supply station A, the path that accommodating groove 12a1, the end are drawn out of, raise member and have the relation that goes up rough alignment at above-below direction (vertical direction).
That is, raise member 20 aim at supply stations accommodating groove 12a1 the below and be arranged to can lifting, raise member and have adsorption hole 20a in the surface thereon, the stream 20b of the negative pressure air that is communicated with adsorption hole is formed on the axis direction.
Electronic unit W is from the main body 14a of feed appliance, the mode of pushing from behind to be linked to be delegation in the path 14b1 of linear loader transmits, so that be pressed and the mode of carrying the upper surface that raises member 20 when arriving the passage portion that is drawn out of the end of to as file leader's electronic unit W1, make to raise member and be roughly and carry out standby (with reference to (A) of Fig. 4) on the conplane position in the bottom surface of surface and path thereon.
In addition, be set as liftable, both can liftably be arranged at the linear loader 14b of feed appliance, also can be provided with dividually liftably supporting the supporting member and the linear loader that raise member as long as raise member 20.
File leader's electronic unit W1 arrives the passage portion that is drawn out of the end of to and carries the upper surface that raises member 20 and continue to be pressed when transmitting, shown in Fig. 3 (B), the forelimb that advances to the stopper end 14b2 ' of stopper sheet is blocked and rests on the upper surface that raises member, and electronic unit is aimed on above-below direction (vertical direction) with the accommodating groove 12a1 of supply station and located.
When the electronic unit W1 that detects the file leader when transducer etc. is positioned at the position (forelimb that advances to stopper end 14b2 ' is blocked and has carried out the position aimed at accommodating groove 12a1) of regulation, negative pressure air acts on the stream 20b that raises member, produces absorption affinity among Biao Mian the adsorption hole 20a thereon and electronic unit W is adsorbed onto its upper surface.And, make with the state that electronic unit W2 is adsorbed onto its upper surface to raise member 20 and rise, thereby being raised the accommodating groove 12a1 that is positioned at supply station, takes in electronic unit.Be raised among the accommodating groove 12a1 and when being contained, turntable 12 carries out indexing transfer when electronic unit is pushed, electronic unit slides on supporting disk 13 with the state that is received to groove and takes in and is transmitted, and leaves from supply station A.
In addition, rise to when entering in the accommodating groove 12a1, can hinder the indexing transfer of turntable 12, therefore raise member and obviously can not enter in the accommodating groove when raising member 20.
