Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
195 words
A device for feeding electronic components packed in a tape to a pick-up position, said device being an exchangeable cassette and comprising: (a) a supply reel for said tape, (b) a holder for said supply reel, (c) a feeding mechanism provided with a feeding pin and coupled to said supply reel for moving said components to said pick-up position, (d) a locking mechanism provided with a locking pin coupled to said supply reel for preventing undesired rotation of said tape, (e) an ejection mechanism provided with an injection pin and coupled to said feeding mechanism for ejecting components from said tape at said pick-up position, (f) a wind-up mechanism coupled to said supply reel for guiding said tape along a path coinciding with said pick-up position, (g) sliding mechanism coupled to said feeding mechanism and said wind-up mechanism for driving said feeding and said wind-up mechanism, (h) and a housing secured to and providing a common support for said holder, and said mechanism and supplied with a support for said supply reel, a transport channel constituting a guide for said tape with said components to said pick-up position and a bearing for a take-up reel.
Claim 2
Independent Claim
195 words
A device for feeding electronic components packed in a tape to a pick-up position, said device being an exchangeable cassette and comprising: (a) a supply reel for said tape, (b) a holder for said supply reel, (c) a feeding mechanism provided with a feeding pin and coupled to said supply reel for moving said components to said pick-up position, (d) a locking mechanism provided with a locking pin coupled to said supply reel for preventing undesired rotation of said tape, (e) an ejection mechanism provided with an injection pin and coupled to said feeding mechanism for ejecting components from said tape at said pick-up position, (f) a wind-up mechanism coupled to said supply reel for guiding said tape along a path coinciding with said pick-up position, (g) sliding mechanism coupled to said feeding mechanism and said wind-up mechanism for driving said feeding and said wind-up mechanism, (h) and a housing secured to and providing a common support for said holder, and said mechanism and supplied with a support for said supply reel, a transport channel constituting a guide for said tape with said components to said pick-up position and a bearing for a take-up reel.
Claim 3
Dependent Claim
110 words
A device as claimed in claim 1, characterized in that the sliding mechanism comprises a feeding slide and a driving slide, which slides, viewed in the feeding direction, are positively coupled to each other by a shape connection and, viewed in a direction transverse to the feeding direction, are frictionally coupled to each other by a force connection, the feeding pin being secured on the feeding slide and the locking pin being secured on a lever rotatable about a fixed pivot shaft and co-operating with the feeding slide, while the driving slide co-operates with a cam system operative in the feeding direction and consisting of cam tracks and cam followers.
Claim 4
Dependent Claim
19 words
A device as claimed in claim 2, characterized in that the cam tracks are provided on exchangeable cam plates.
Claim 5
Dependent Claim
38 words
A device as claimed in claim 2 or 3, characterized in that the feeding slide is provided with guides co-operating with the driving slide, the driving slide and the guides being pressed against each other by a spring.
Claim 6
Dependent Claim
50 words
A device as claimed in claim 4, characterized in that the driving slide is displaced during the forward stroke against the action of the spring, the backward stroke taking place under the action of the spring, the spring simultaneously pressing the cam tracks and the cam followers against each other.
Claim 7
Dependent Claim
30 words
A device as claimed in claim 1, characterized in that the sliding mechanism is provided with an abutment arm which co-operates with a driving pin for driving the wind-up mechanism.
Claim 8
Dependent Claim
80 words
A device as claimed in claim 6, characterized in that the wind-up mechanism mainly comprises a driving disk on which the driving pin is secured, a friction coupling, a driven disk, a reel rim, a detachable reel flange and a cover plate connected to the housing, a feeding pawl being provided on the driven disk and a locking pawl being provided on the cover plate, which pawls co-operate with a pawl toothing at the inner periphery of the reel rim.
Claim 9
Dependent Claim
19 words
A device as claimed in claim 1, characterized in that the reel holder is pivotally secured on the housing.
