a) a first pivot axis S3, by means of which the eyeglass lens can be moved between the eyeglass lens magazine and the orienting station or the transport arm,
b) a second pivot axis S4, by which the eyeglass lens can be brought into an upside down position.
8. The blocking device according to claim 1, wherein one station is configured as a turning station with an axis of rotation D1, by which the block with the blocked-on eyeglass lens can be turned about a center axis of the block.
9. The blocking device according to claim 1, wherein at least two or three blocking stations are provided, each of which can be accessed via the transport arm and the conveying arm, andor one station is configured as a block magazine which can be accessed at least via the conveying arm.
10. The blocking device according to claim 1, wherein a dispensing unit for bonding compound is provided, having an axis of movement B1, by which the dispensing unit can be positioned in at least two different positions P1, P2, P3 in the area of the particular blocking station.
11. A method for blocking an eyeglass lens on a block, comprising the steps of:
a) picking a first eyeglass lens up by a transport arm,
b) handing the first eyeglass lens by the transport arm to a first blocking station,
c) blocking the first eyeglass lens onto the first block and leaving for a cooldown time in the blocking station,
d) during the cooldown time, passing a second eyeglass lens to the transport arm by a handover unit, being transported via the transport arm to the second blocking station and setting it down in the second blocking station, and
e) during this transport process and before the respective eyeglass lens is set down at the respective blocking station, the conveying arm removes a block from a block magazine and sets it down in the corresponding blocking station.
12. The method according to claim 10, wherein the conveying arm after the cooldown time removes the blocked-on eyeglass lens with a block from the particular blocking station and delivers it to the handover unit or the turning station.
13. The method according to one of claims 10, wherein the eyeglass lens is brought to bear against the abutment element by the handover unit or by the transport arm for the purpose of orienting the relative position to the conveying arm.
14. The method according to claim 13, wherein a retaining force of the handover unit or the transport arm is reduced as it is placed against the abutment element, so that a relative movement of the eyeglass lens relative to the handover unit is made possible.
15. The blocking device according to claim 2, wherein the retainer has a translatory axis T3 by which the retainer can be moved relative to the conveying arm in a direction parallel to the pivot axis S2, and wherein one station is configured as an orienting station, having an abutment element against which the eyeglass lens can be placed for orienting a relative position between the eyeglass lens and the retaining head.
16. The blocking device according to claim 15, wherein the orienting station has a translatory axis T4, by which the abutment element can be moved relative to the transport arm, wherein the abutment element has two abutment spikes, which can be brought between the retaining head and an eyeglass lens attached to it, wherein one handover unit and one eyeglass lens magazine are provided, wherein the handover unit serves to pick up from the eyeglass lens magazine and hand off to the eyeglass lens magazine and the handover unit has: a) a first pivot axis S3, by means of which the eyeglass lens can be moved between the eyeglass lens magazine and the orienting station or the transport arm, b) a second pivot axis S4, by which the eyeglass lens can be brought into an upside down position.
17. The blocking device according to claim 16, wherein one station is configured as a turning station with an axis of rotation D1, by which the block with the blocked-on eyeglass lens can be turned about a center axis of the block, wherein at least two or three blocking stations are provided, each of which can be accessed via the transport arm and the conveying arm, andor one station is configured as a block magazine which can be accessed at least via the conveying arm, and wherein a dispensing unit for bonding compound is provided, having an axis of movement B1, by which the dispensing unit can be positioned in at least two different positions P1, P2, P3 in the area of the particular blocking station.
18. The method according to claim 12, wherein the eyeglass lens is brought to bear against the abutment element by the handover unit or by the transport arm for the purpose of orienting the relative position to the conveying arm.
19. The method according to claim 18, wherein a retaining force of the handover unit or the transport arm is reduced as it is placed against the abutment element, so that a relative movement of the eyeglass lens relative to the handover unit is made possible.
