This application is a National Stage of International Application No. PCT/NZ2007/000364, filed Dec. 13, 2007.
This invention relates to improvements in and relating to animal tag applicators and/or tags therefor.
More particularly but not exclusively the present invention relates to applicators and/or tags which are suitable for farm animals such as sheep.
To the present time many tag applicators are able to be used solely for the application of a single tag to an animal, typically to its ear. Such applicators require the loading of discrete tags ready for each application with the consequential time and effort that this involves.
Other applicators however, have proposed the use of a strip of tags which can be loaded into an applicator so that tags can be sequentially dispensed from the applicator.
In U.S. Pat. No. 5,234,440, (Cohr), for example, a strip of tags is loaded into a magazine positioned alongside the applicator body. To dispense an individual tag, the operation of the applicator results in the front tag in the magazine being moved into the applicator body where a blade of a slider will sever the leading tag from the tag strip in the magazine and a tag advance mechanism will move the now separated tag to the front of the applicator where it can be secured to the animal. Typically such a side loading operation and the early separation of the tag from the strip has been found to provide various disadvantages, especially in the difficulty and unreliability of its operation.
In another applicator, as described in New Zealand patent 524953, (Eadie), this again provides a flat strip of tags which is located transverse of an applicator body. The tags are then fed individually and sequentially into the applicator body by a tooth wheel. This design results in the first two tags of the strip being unusable in each case and the side-loading operation also presents difficulties.
It is an object of at least preferred embodiments of the invention to provide an animal tag applicator and/or strip of tags which will at least obviate difficulties in previous applicators and/or strip of tags, or which at least will provide the public with a useful choice.
Further objects of the invention will become apparent from the following description.
According to one aspect of the present invention there is provided an animal tag applicator, including an applicator body adapted to receive therein a strip of longitudinally connected tags, transporting means provided for the body and adapted in use to engage with the said strip of tags, so that the strip is moved substantially longitudinally relative to the applicator body to position a front-most tag of the strip at a dispensing position, said applicator further including a dispensing means adapted to engage, in use, with said front-most tag so that it is separated from the next adjacent tag in the strip at said dispensing position to be secured about part of an animal, said transporting means being adapted to then be re-engageable with said strip to move the next front-most tag to said dispensing position.
Preferably, the transporting means is adapted to pull the strip longitudinally relative to the applicator body.
Preferably, the transporting means is adapted to engage a portion of the front-most tag in pulling the strip.
Preferably said applicator body is adapted to receive said strip of tags in which each tag of said strip includes a male portion flexibly interconnected with and facing towards, a female portion, the engagement of the dispensing means with the front-most tag resulting in the engagement of the male portion with the female portion and the separation of the front-most tag from the next adjacent tag.
According to a further aspect of the present invention a strip of tags for use in an applicator as defined in any one of the four paragraphs immediately above includes each tag having a male portion and a female portion, a connecting portion longitudinally connecting adjacent tags together to form said strip, said strip being adapted to engage in use with a transporting means so that the strip can be moved substantially longitudinally relative to an applicator body towards a dispensing position, said tags being adapted to be selectively engagable by a dispensing means whereby a front-most tag of the strip can be separated from its next adjacent tag so that said front-most tag can be secured about part of an animal.
Preferably said strip of tags has the male portion of each tag of said strip facing towards a respective said female portion.
According to a further aspect of the present invention, there is provided an animal tag applicator and/or an animal tag strip substantially as herein described with reference to the accompanying drawings.
Further aspects of this invention which should be considered in all its novel aspects will become apparent from the following description by way of example of possible embodiments.
a), (b), (c) (d) and (e): Show respectively, plan, side, rear, front and underneath views of a strip of tags according to one possible embodiment of the invention;
Referring to the accompanying drawings, an applicator according to one possible embodiment of the invention is referenced generally by arrow 1.
The applicator 1 may be manufactured from any suitable material or materials, such as metal and plastics. It is shown having a first handle portion 2 leading to a lower front jaw 6. The handle portion 2 provides an applicator body portion and is adapted to accommodate at least part of an elongate strip of tags 10. The handle 2 may as shown be in two parts 2A, 2B which may be screwed together at connection portion 40. It is envisaged that in some embodiments, for a shorter tag strip, the rear part of the handle 2B could be detached. A lower handle 3 is shown associated with a front upper jaw 7. The handles 2, 3 are shown pivoted together at 8.
The tags 10 of the strip, see

In this jaw-open position, see particularly

It will be appreciated therefore that the strip of tags 10 of the present invention is moved in a single longitudinal direction after the front-most tags have been separated from the strip and tagged to the animal, thus avoiding the problems associated with the lateral or sideways feed into the applicator body of earlier applicators. By pushing behind the front-most tag the rest of the strip of tags is in effect pulled through the applicator body. Also the strip of tags 10 is moved in its entirety through the applicator body so avoiding any premature separation of the individual tags from the tag strip. Additionally there is no wastage in that all the tags of the strip can be used.
Once a strip of tags has been loaded into the applicator 1 of the present invention, it can then be automatically used for sequential tagging operations until all the tags have been used up, and when a relatively simple re-loading operation can be effected.

The lost motion slot 43 enables the rearward movement of the pusher 18 into position behind the next tag 10. This is achieved by the lost motion preventing the slider 17 from moving forward as the tagger 1 is opened, after applying the tag 10A. This allows the blades 31A to clear the front edge of the next tag 10 before that tag moves forward to the front position in the jaws 6, 7. The delay or dwell is only for a short time before the pusher 17 takes up the “slack”. This avoids the blades 31A from preventing the next tag 10 from moving if the slider 7 was to move immediately, causing a jam.

It is seen therefore that the tagger and tag strip of the present invention may provide speedy and effective sequential tagging operations for a number of animals without reloading.
Where in the foregoing description, reference has been made to specific components or integers of the invention having known equivalents, then such equivalents are herein incorporated as if individually set forth. Also where reference in the specification, has been made to “ear tag”, it is to be understood that this encompasses tags and applicators therefor which may be suitable for application to any part of an animal's body.
Although this invention has been described by way of example and with reference to possible embodiments thereof, it is to be understood that modifications or improvements may be made thereto without departing from the scope of the invention as defined in the appended claims.
