The label is applied to the tip of the adjacent label for angular displacement, and the tip receives a reaction force from the guide surface 6b of the peeling guide member 6, and this reaction force causes the claw attachment member 28 to be angularly displaced. The adjustment stop lever 39 is angularly displaced, the teeth 41a of the sawtooth plate 41 are engaged with the adjustment claws 43 of the adjustment piece 27, and the adjustment piece 27 is positioned and stopped at a predetermined position.

4c and is slidable along these elongated holes, and furthermore, the elongated hole 39 at the end of the adjustment stop lever 39
It passes through ba.

The adjustment stop lever 39 is rotatably mounted at an intermediate position with a support shaft 40 provided on the side plate 1b, and the engagement shaft 36 slidably passes through an elongated hole 39a at one end near the sensing claw 29. , has a sawtooth plate 41 fixed to the other end. This sawtooth plate 41 is integrally fixed to the adjustment stop lever 39 with the teeth 41a facing the feed claw 18 side of the feeding mechanism 5 and substantially along the sliding direction of the feed claw 18.

The engagement release member 42 has a substantially V-shape and is pivoted at a predetermined position on the side plate 1b with a small lever shaft 42d, and has a tip 42b on the side close to the adjustment stop lever 39 and a base end 42a on the segment side. The base end 42a has a rod-shaped projection 42c that projects inward, and this rod-shaped projection 42c is connected to the segment 4.
It engages with a suppressing piece 4b formed outward on the edge of a, and its tip faces a fan-shaped groove 4C connected to the suppressing piece 4b.

This suppressing piece 4b presses the rod-shaped projection 42c and rotates the engagement release member 42 in the direction shown by arrow A during the return stroke of the handle 4 returning to the open state. Due to the suppressing action of the pressing piece 4b, the roller on the distal end 42b side of the disengagement release member 42 presses the end of the adjustment stop lever 39 on the serrated plate 41 side, and the distal end of the pawl mounting member 28 and The sensing claw 29 is displaced in the direction away from the tape, and by the action of the tension spring 37, the sensing claw 29 is restored from the state where it stood against the tape to its original position along the tape, for the next engagement. You can prepare.

Next, the operation of the label pasting machine according to the above embodiment of the present invention will be explained.

The tape T passes through the partial circumferential surface 1d of the concave portion 1g, the plane 1e, and between the guide surface 6b of the peeling guide member 6, the guide plate 33, and the sensing claw 29, and is turned at an acute angle at the tip of the peeling guide member 6. Instead, a center hole is formed in the outer periphery of the tape holding member 3 so that the holding plate 13g and the inside of the swinging door body 13 are aligned, and the tip of the tape holding member 3 is led out through the teeth 13a of the swinging door body 13. It is installed in a predetermined position with a loose fit.

When the handle 4 which is opened with respect to the grip 1c is operated and the handle 4 is closed, the tips of the teeth 24a of the claw pieces 24 touch the swinging door during the forward stroke of the feed claw 18 that slides along the guide rod 26a. The receiver of the body 13 captures the tape T between it and the guide plate 31 and feeds it out. At this time, the direction of the tape T is changed by the peeling guide member 6, but the label L adhered to the tape T changes its direction. The tape T is peeled off in an attempt to move straight without moving, and the tip of the sensing claw 29 engages with the tip of the label L adjacent to the peeled label L, causing an angular displacement at the tip of the label, causing the label to stick. The tip of the peeling guide member 6 fixed to the machine body 1 stands up against the guide surface 6b and receives a reaction force from the guide surface 6b to angularly displace the claw attachment member 28 and move the engagement shaft 36. Due to this movement of the engagement shaft 36, the adjustment stop lever 39 is angularly displaced, the sawtooth plate 41 moves toward the joint piece 27, and the tip of the adjustment pawl 43 is caught by the teeth of the sawtooth plate 41, and the adhesive pitch of the label is adjusted. The sliding piece 22 and the feed pawl 18 are positioned and stopped at the matched predetermined position. The label L remains on the pressing piece 7b of the pressing roll 7 with the adhesive side facing outward. This stuck label L can be pressed onto the object and affixed at a predetermined position. Next, when the handle 4 is released, the handle 4 returns to the closed state due to the action of the tension spring 8, and at this time, the adjusting pawl 43 contacts the slope of the teeth of the sawtooth plate 41, and the receiver moves away from the portion 27c. However, within the last 3 degrees of this backward stroke, the suppressing piece 4b of the segment 4a comes into contact with the rod-shaped protrusion 42c, causing the engagement release member 42 to be angularly displaced and the roller on the tip 42b side of the engagement release member 42 to be removed. The adjustment stop lever 39 is pressed, whereby the sensing claw 29 moves in a direction away from the guide surface 6b and the tape T, and its tip moves away from the tip of the label L, and is restored to its original position by the action of the tension spring 37.

In this label pasting machine, the tape holding member 3, the peeling guide member 6, and the swinging door body 13 are cantilevered, and only one end side is supported. It can easily accommodate tapes of a wide range of widths, from long lengths to wide tapes that protrude.

Note that the label sticking machine according to the present invention is not limited to the above-mentioned embodiment, and may be of a type that uses a pair of rollers as a feeding mechanism. A circular saw-shaped disk with teeth is attached to the roller shaft, and an adjustment pawl 43 is provided on the adjustment stop lever 39 side, so that when the adjustment stop lever 39 is angularly displaced, the adjustment pawl 43
It is sufficient if the roller is brought into contact with the teeth of a circular saw-shaped disk to stop the rotation of the roller, or it may be of various other conventionally known types, and various other modifications are possible. .

(Effects of the Invention) The present invention includes a swingable claw attachment member configured as described above, and a label that is swingably attached to the tip of the claw attachment member and adhered to the tape when the tape is fed out. a sensing pawl that engages with the tip of the pawl for restorable angular displacement and angularly displaces the pawl attachment member in conjunction with the angular displacement; The tape is automatically fed out in accordance with the adhesion pitch of the label by being equipped with an adjustment stop lever that automatically adjusts and matches the tape feeding length to the adhesion pitch of the label and stops the movement of the feeding mechanism. It is very convenient because the length can be adjusted and delicate positioning adjustments are not required, and it is equipped with an engagement release member that disengages the sensing claw from the label tip in conjunction with the return movement of the handle. , it has the effect of automatically making preparations so that there will be no hindrance to the next tape feeding operation.
