Method and apparatus for facilitating cutting of a unit dose blister card
View Patent ↗An apparatus for facilitating cutting of unit dose blisters from a blister card is provided. The apparatus may include a platform, a clamp, a blade and a sensor. The blister card may be positionable on the platform for cutting. The clamp may be positionable to hold a portion of the blister card in contact with the platform for cutting when the clamp is seated. The clamp may be operatively coupled to a guillotine head. The blade may also be operatively coupled to the guillotine head. The guillotine head may be configured to move the blade through a range of motion that intersects a plane of the platform. The sensor may be positioned to detect a seating status of the clamp to enable control of movement of the guillotine head based on the seating status.
1. An apparatus for cutting a blister card, the apparatus comprising:
a platform on which the blister card is positionable for cutting;
a guillotine head comprising at least one elastic element, wherein the at least one elastic element comprises a compression spring;
a clamp comprising a portion of a card holder, the card holder being movable in a channel defined by a base, the clamp being positionable to hold a portion of the blister card in contact with the platform for cutting when the clamp is seated, the clamp being operatively coupled to a guillotine head by the at least one elastic element;
a blade operatively coupled to the guillotine head, the guillotine head being configured to move the blade through a range of motion that intersects a plane of the platform; and
a sensor positioned to detect a seating status of the clamp to enable control of movement of the guillotine head based on the seating status,
wherein the at least one elastic element is compressed to enable continued movement of the guillotine head through the range of motion that moves the blade to a position that intersects the plane of the platform to cut the blister card in response to the sensor detecting a seated condition of the clamp, and
wherein the blade is in slidable contact against the base as the at least one elastic element is compressed.
2. The apparatus of claim 1 , wherein the sensor determines a location of the clamp relative to the surface of the platform.
3. The apparatus of claim 1 , wherein the sensor is configured to detect the seating status after the at least one compression spring begins to compress and before the guillotine head passes the blade through intersection with the plane of the platform.
4. The apparatus of claim 1 , wherein the guillotine head is positioned to provide movement of the guillotine head in a plane that is substantially perpendicular to the plane of the platform.
5. The apparatus of claim 1 , wherein the clamp provides pressure to hold a portion of the blister card in contact with the platform such that the pressure increases while the blade initially passes through the plane of the platform.
