Title:
TABLET CONTAINER TRANSFER DEVICE
Document Type and Number:
WIPO Patent Application WO/2001/076982
Kind Code:
A1
Abstract:
A tablet container transfer device wherein an arm (15) comprising a pair of gripping pieces (25) for gripping a tablet container (11) and a driving motor (24) for opening/closing the gripping pieces (25) is turned and vertically moved, thereby transferring the tablet container (11) from a tablet filling section (4) to a storing shelf (1). A value obtained by adding a margin current to a current value found during the normal driving of the driving motor (24) is set as a threshold. The device further includes a control means whereby if the current value exceeds the threshold as the load on the driving motor (24) increases when the tablet container (11) is gripped by the gripping pieces, the operation of the driving motor (24) is stopped. This makes it possible to produce the device at low cost by the existing facilities without adding a sensor or the like.
