DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a label sticking machine for sticking a large number of labels on a wound tape one by one to a product.

[0002]

2. Description of the Related Art A label sticking machine of this type draws out a tape by gripping a handle, peels off a label adhered to the tape, and sticks the label on an object. In order to regulate the sliding stroke length of the sliding piece, a conventional label sticking machine is provided with a stopper that can move within the sliding stroke, and the stopper is positioned and fixed with a screw or the like so that the tape feeding length can be adjusted. Had been adjusted. Further, various mechanisms for providing a label sensor and stopping a subsequent label have been proposed.

[0003]

However, in the conventional label sticking machine as described above, if the stopped label is slightly riding on the sensor, when the sensor is lifted in the next operation, the label is simultaneously read. Since it is lifted and sent out, there is a drawback in that it hinders peeling and sending out work.

An object of the present invention is to provide a label sticking machine in which a label does not get on a label sensor and is not lifted in view of the conventional drawbacks.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the gist of the present invention is to feed a tape by a feeding mechanism operated by a handle operation, and to peel off a label adhered to the tape. A label attaching machine for attaching the label to an object, wherein the swingable sensing claw and label press attaching member, and the tape swingably attached to the tip of the sensing claw and label press attaching member. When feeding out, a sensing claw and label presser that engages with the tip of the label adhered to the tape to recover and angularly displaceably and angularly displaces the sensing claw and label presser mounting member in conjunction with the angular displacement; The tape dispensing length that is angularly displaced in conjunction with the angular displacement of the sensing claw and label press attaching member and is dispensed by the dispensing mechanism is automatically adjusted to match the adhesive pitch of the label, and And adjusting stop lever for stopping the movement of the mechanism out, and a disengagement member for releasing the engagement of said detecting pawl and label presser to label the tip in conjunction with the return movement of the handle, sensing displaced the angle Claw and label holder
Has a label holding part and a tip part, and the label is
When contacting the front end, the label presser
Holds the upper front and senses with the tension spring
The tip touches the label when the claw and label holder is lowered.
Is to delay the time it takes to do so.

[0006]

In the label sticking machine according to the present invention, since the label stopper and the label presser have an integral structure, it is possible to stop the label and at the same time physically press the leading end of the label, thereby preventing the label from getting on the label. .

By the pressing action of the pressing piece 4b, the roller on the tip end 42b side of the engagement releasing member 42 is adjusted by the adjustment stop lever 39.
Of the claw attachment member 28 and the sensing claw and label presser 29 are displaced in a direction of separating from the tape through the engaging shaft 36 by the action of the tension spring 37. The label presser 29 is restored from the standing state with respect to the tape to the original position along the tape,
It is possible to prepare for the next engagement (see FIGS. 5 and 6).

Next, the operation of the label sticking machine according to the embodiment of the present invention will be described. The tape T passes from the partial circumferential surface 1d of the concave portion 1g to the guide surface 6b of the peeling guide member 6 through the flat surface 1e, the guide plate 33 and the sensing claw / label presser 29, and the tape T is directed at the tip of the peeling guide member 6. Is sharply changed to fit inside the holding plate 13g and the door body 13 and a center hole is loosely formed in the outer periphery of the tape holding member 3 so that the front end is guided to the outside through the teeth 13a of the door body 13. It is fitted and mounted at a predetermined position.

When the handle 4 is closed by operating the handle 4 opened with respect to the grip 1c, the guide rod 26
The leading end of the tooth 24a of the claw piece 24 catches the tape T between the receiving guide plate 31 of the door body 13 and feeds out the tape T in the forward stroke of the feed claw 18 sliding along a. At this time, the direction of the tape T can be changed by the peeling guide member 6, but the label L adhered to the tape T is peeled from the tape T so as to proceed straight without changing the direction, and the sensing claw and label presser 29 The leading end of the label L1 adjacent to the peeled label L engages, is angularly displaced at the leading end of the label L, and the leading end stands on the guide surface 6b of the peeling guide member 6 fixed to the bonding machine main body 1. Upon receiving the reaction force from the guide surface 6b, the claw mounting member 28 is angularly displaced to move the engagement shaft 36.

The adjustment stop lever 39 is angularly displaced by the movement of the engagement shaft 36, the saw-tooth plate 41 moves toward the adjustment piece 27, the tip of the adjustment claw 43 is hooked on the teeth of the saw-tooth plate 41, and the label is The slide piece 22 and the feed claw 18 are positioned and stopped at a predetermined position corresponding to the bonding pitch. The label L remains at the pressing piece 7b of the pressing roll 7 with the bonding surface facing outward.

The remaining label L can be pressed against an object and attached to a predetermined position. Next, when the hand is released from the handle 4, the handle 4 returns to the closed state by the action of the tension spring 8, and at this time, the adjusting claw 43 comes into contact with the tooth slope of the sawtooth plate 41 and moves while separating from the receiving portion 27c. Within the last three degrees of the return stroke, the pressing piece 4b of the segment 4a comes into contact with the rod-shaped projection 42c, and the disengagement member 42 is angularly displaced, so that the roller is located on the tip 42b side of the disengagement member 42. The adjustment stop lever 39 is pressed, whereby the sensing claw and label presser 29 moves in a direction away from the guide surface 6b and the tape T, and the leading end is separated from the leading end of the label L1 and restored to the original position by the action of the tension spring 37. . At this time, the movement of the label by the tension spring 37 and the sensing claw / label press 2
There is a time difference in the descent of 9.

In this label sticking machine, the tape holding member 3, the peeling guide member 6 and the door 13 are of a cantilever type, and only one end is supported. It is possible to easily cope with tapes having a wide range of widths, such as wide ones protruding from the length of the member.

The label sticking machine according to the present invention is not limited to the above embodiment, but may be of a type using a pair of rollers as a feeding mechanism. A circular saw-shaped disk having serrated teeth is mounted on the roller shaft, and an adjusting claw 43 is provided on the adjustment stop lever 39 side. When the adjustment stop lever 39 is angularly displaced, the adjustment claw 43 is turned into a circular saw-shaped circle. The rotation of the roller may be stopped by bringing the roller into contact with the teeth of the plate, and various other types known in the art may be used, and various other modifications are possible.
