| 摘要 |
The invention relates to a lock (1) which can be actively released and locked by control technology, particularly for use in automatic storage machines having a plurality of compartments with compartment doors (2) which are to be opened individually, and to an automatic storage machine having at least one such lock (1). The lock (1) comprises a detent pawl (14), which can lock a locking element (9), which is permanently connected to a compartment door (2), in the lock such that the compartment door (2) can be held in closed position. The lock further has a first electric drive element (17) which transitions the detent pawl (14) from the locking position to a release position upon the applying of electrical power, such that the compartment door (2) can be opened. The lock (1) further comprises a security device (32), which prevents an automatic reset of the detent pawl (14) from the release position to the locking position when the lock (1) is in an unpowered state or the automatic storage machine is in an unpowered state, and an unintentional, accidental or improper locking of a compartment door can thus be avoided. In order to properly lock a compartment door, the security device (32) of the lock (1) comprises a second electric drive element, by means of which the detent pawl (14) can be transitioned back to the locking position thereof upon the applying of electrical power to said second electric drive element during closing of the compartment door (2). |

1. A lock (1) which can be actively released and locked by control technology, particularly for use in automatic storage machines having a plurality of compartments with individually opening compartment doors (2), with a locking element (9) insertable into the lock (1), for example a locking hook or locking bolt, which locking element (9) can be locked in the lock (1) and thereby keeps a compartment door (2) securely connected to the locking element (9) in a closed position, with a detent pawl (14) which can be adjusted rotationally to a limited degree, which on adopting its locking position (36) via at least one movably mounted coupling member (12) cooperates with the locking element (9), wherein the forces from the locking element (9) resulting from an opening force on a held closed compartment door (2) are transmitted via the at least one coupling member (12) to the detent pawl (14) and from a pivot axis (23) of the detent pawl (14) to a housing (3) of the lock (1), and with a first electric drive element (17) coupled movably to the detent pawl (14), in particular a first electromagnet (18), for the controlled adjustment of the detent pawl (14) from the locking position (36) into a release position (41), wherein the lock (1) comprises a security device (32), which security device (32) comprises a blocking element (33) which blocking element (33) with a detent pawl (14) located in release position (41) adopts a blocking position (40), and wherein a means (41a) for holding the blocking element (33) in the blocking position (40) is designed such that in the unpowered state of the lock (1) or in the unpowered state of a higher control device (64) functionally connected to the lock (1), the automatic restoring of the detent pawl (14) from the release position (41) to the locking position (36) is prevented, and wherein the security device (32) comprises a second electric drive element (47), in particular a second electromagnet (48), by means of which second electric drive element (47) on charging with electric power the blocking element (33) can be moved from its blocking position (40) into a release position (38) so that with an existing power supply for the lock (1) or the higher control device (64) functionally connected to the lock (1) during the closing of the compartment door (2) the detent pawl (14) can be moved into its locking position (36). |
