Abstract: 1388442 Label applicators SHINSEI INDUSTRIES CO Ltd 5 June 1972 [5 June 1971] 26162/72 Heading B8F A hand operated label applicator has labels peeled from a backing tape at an edge 40, the leading edge of a label 12a being detached being held by a member 62 which moves with the label until the label registers with a presser 90; the presser is then actuated by a spring 140 and applies the label to an article. The label tape is led from a reel 10 over guide rollers 31 to the separating edge 40, the spent tape passing between guide and clamping members 70, 72 out of the applicator. The applicator is operated by pivoting a lever 210 towards a handle 22, causing a cam surface 213 of the lever to release a clamping part 721 of the guide member 72 to free the spent tape. Lever 210 is pivotally connected at 231 to a lever 230 which is thus pivoted about a pin 212 and in turn pivots a lever 240 about an adjustable fulcrum 242. Lever 240 acts through a spring 250 on a lever 82 which is pivoted to a lever 80 and initially pivots lever 82 to clamp the tape between the ends of levers 80, 82, and subsequently pivots the levers 80, 82 together in order to feed the tape. A pawl 63 is pivoted to a tape holder 64 which is pivoted to a frame 61 carrying the label holder member 62 and reciprocatable in guideways 23 provided in the applicator casing. A spring 632 biases an end 631 of the pawl 63 into engagement with the leading end of the penultimate label 12b on the tape, and the tape holder 64 clamps the label tape against a surface 614 of the frame 61. Movement of the tape thus causes the frame to shift upwardly until the end label 12a registers with the presser 90, at which point the frame 61 is held by a stop 65 with the leading edge of the label supported by the member 62. The label feed is thus stopped, but futher movement of the lever 210 is permitted due to the spring 250. Meanwhile the movement of the lever 230 has tensioned the spring 140 of the presser mechanism, the presser being held inoperative by a latch 160. At the end of the movement of lever 210 a member 150 releases the latch 160 and the spring 140 actuates the presser 90 which applies the label to an article. On release of lever 210, it is pivoted clockwise by a spring, and a latch 271 is shifted leftwardly engaging a latch arm 633 of the label sensing pawl 63 and shifting it clockwise and tape holder 64 anti-clockwise to release the label tape. The frame 61 is then shifted downwardly by a spring 615, this movement releasing pawl 63 from the latch 271 so that the pawl 63 is shifted anti-clockwise into contact with the tape by the spring 632. When the pawl engages the leading end of the penultimate label it causes holder 64 to pivot into contact with the tape and the frame 61 to be held in its initial position. The label holder member 62 is adjustable in the frame 61 and may comprise a plurality of elements to suit labels of different shapes. The label feed can be adjusted for labels of different sizes by adjustment of the fulcrum 242 which is provided by a pin on a lever 243 pivoted at one end and having a pin at its other end selectively engageable in a number of holes provided in the applicator casing.
