Abstract
A tag applicator, and a method, for applying a tag, having an elastic loop, to a product. The tag applicator includes a linear actuator, and a pair of tag arms, one end of each being pivotably connected to the linear actuator. The two arms are biased toward each other, such as by a spring. A separator is positioned between the tag arms, so as to force the tag arms to separate as the linear actuator extends. A finger or tag hook is connected at the end of each tag arm, configured and positioned to connect to or insert into the elastic loop, and to extend the elastic loop as the tag arms are separated. With the tag loop held open, the product moves into the loop, and the tag is thereby applied to the product.
Claims8
A tag applicator for applying a tag to a product, the tag having an elastic loop connected to a certain point on the tag, the tag applicator comprising:
- a linear actuator having a movable portion and a stationary portion;
- a pair of tag arms, one end of each being pivotably connected to and moving with the movable portion of the linear actuator;
- a single spring biasing the two arms toward each other;
- a separator, positioned between the tag arms and which is mounted so as not to be movable with respect to the stationary portion of the linear actuator, so as to force the tag arms to separate as the linear actuator extends;
- and
- a finger connected to each tag arm, configured and positioned to connect to the elastic loop, and to extend the elastic loop as the tag arms are separated so as to form the loop into a triangle, with the corners of the triangle being formed by the two fingers and the certain point on the tag, and into which triangle the product is moved in order to apply the tag to the product.
A tag applicator for applying to a product a tag having an elastic loop, from a bandolier of tags each having an elastic loop, the applicator comprising:
- a pair of infeed rollers, forming an infeed nip therebetween;
- a pair of outfeed rollers, forming an outfeed nip therebetween, and cooperating with the infeed rollers to separate one tag from the bandolier of tags, and position the elastic loop from that now separated tag in a predetermined location;
- a linear actuator;
- a pair of arms pivotably connected to the linear actuator, and biased toward each other;
- a separator, positioned between the arms, so as to force the arms to separate as the linear actuator extends;
- and
- a tag hook connected to each arm, configured and positioned to connect to the elastic loop, and to extend the elastic loop as the arms are separated.
A tag applicator for applying a tag to a product, the tag having an elastic loop connected to a connection point on the tag, the tag applicator comprising:
- a linear actuator having a movable portion and a stationary portion, the linear actuator capable of extending the movable portion with respect to the stationary portion;
- only two tag arms, one end of each tag arm being pivotably connected to the movable portion of the linear actuator, and the tag arms biased toward each other;
- a separator, positioned between the tag arms and which is mounted so as to remain stationary with respect to the stationary portion of the linear actuator as the movable portion extends, the separator thereby forcing the tag arms to separate as the movable portion of the linear actuator extends;
- and
- two fingers, one finger connected to each tag arm, the fingers configured and positioned to hook to the elastic loop, and to extend the elastic loop as the tag arms separate.
