[Problems to be solved by the invention]
In the conventional label magazine described above, it is difficult to take out the labels one by one if the labels are pressed too hard with the label presser claw, and on the contrary, if the pressing force is weak, the labels pop out and cause trouble. The conventional label presser claw has almost satisfactory performance in terms of pressing the label with an appropriate force. However, the label taken out from the label magazine may have a cut of about several millimeters. A label that has been cut may be peeled off or broken from a flaw or the like. In particular, if the label contains moisture, peeling or breakage is likely to occur.
[0004]
Then, an object of this invention is to provide the label magazine which can prevent the cutting of a label, and its label press nail | claw.

[0007]
The resistance when the label gets over the label presser claw has a correlation with the height of the label engaging portion, and the higher the label engaging portion, the higher the resistance and the higher the possibility that the label will be broken. However, if the heights of all the label engaging portions mounted on the label magazine are uniformly reduced, the force with which the label engaging portion presses the label is insufficient, and the label tends to pop out. Therefore, if the height of some of the label engaging portions is set lower than the height of the other label engaging portions, the labels can be securely placed in the label magazine as compared with the case where the label engaging portions are uniformly lowered. The risk of notching the label while restraining can be reduced. In particular, when incision occurs only in some label presser claws, by forming only the label engaging part of the label presser claw lower than the others, it is possible to reliably prevent the cut while maintaining the effect of pressing the label. it can.

As shown in FIGS. 4 and 5A, the label pressing claw 25 includes a holder 31 that is attached to the inside of the holding frame 24 by using bolts 30 and a claw member that is attached to the tip 31a of the holder 31. 32. The holder 31 has a claw receiver 31 </ b> A and a spacer 31 </ b> B interposed between the claw receiver 31 </ b> A and the holding frame 24. FIG. 5A shows only one label pressing claw 25, but the other label pressing claw 25 basically has the same configuration. However, the claw member 32 may be partially different. The claw member 32 is screwed into the screw hole 31b of the holder 31 with a bolt 33 inserted through a long hole 32a extending in the laminating direction of the label 100, so that the label engaging portion 32b provided at the tip of the claw member 32 is inside the holding frame 24. It is fixed to the holder 31 in a state facing toward By loosening the bolt 33, the claw member 32 can be moved to adjust the position of the label engaging portion 32b in the label 100 stacking direction.
[0017]
The holder 31 can be bent and deformed inside the holding frame 24 with the mounting position of the bolt 30 as a fulcrum. Screw holes 24 a are formed in the holding frame 24 so as to overlap the holders 31, and adjustment screws 34 are attached to the screw holes 24 a. When the knob 34a of the adjusting screw 34 is turned, the protruding amount of the adjusting screw 34 from the screw hole 24a to the inside of the holding frame 24 changes, and the deflection amount of the tip of the holder 31 changes accordingly. Accordingly, the position of the label engaging portion 32b is set in the vertical direction with respect to the label pressing claw 25 attached to the upper and lower surfaces of the holding frame 24, and in the horizontal direction with respect to the label pressing claw 25 attached to the side surface of the holding frame 24. Can be adjusted. The position of the label engaging portion 32b of each claw member 32 is adjusted according to the warp or shape error of the label 100. A coil spring 35 is attached to the outer periphery of the adjustment screw 34. When the adjustment screw 34 is screwed in, the coil spring 35 is compressed, and the repulsive force biases the adjustment screw 34 away from the holding frame 24 (see FIG. 5B).
[0018]
FIG. 6 shows details of the label presser claw 25 used in the label magazine 16. FIGS. 6A to 6C show details of the A type label presser claw 25A, and FIG. The details of the label presser claw 25B are shown. When there is no need to distinguish between the label pressing claws 25A and 25B, they are referred to as label pressing claws 25. Further, the claw member used for the label presser claw 25A is indicated as 32A, and the claw member used for the label presser claw 25B is indicated as 32B. The label pressing claws 25A and 25B are different only in the label engaging portion 32b, and the other configurations are the same.
[0019]
As shown in FIGS. 6A to 6C, the label engaging portion 32b of the label pressing claw 25A is formed on the reference surface 32R and the tapered surface 32c provided over substantially the entire width of the reference surface 32R of the claw member 32A. The front end face 32d is substantially perpendicular to the front end face 32d. The gradient of the tapered surface 32c is almost constant. The intersecting ridge line portion 32e between the tapered surface 32c and the front end surface 32d is processed into a somewhat rounded shape by, for example, sandpaper. On the other hand, the label engaging portion 32b of the label pressing claw 25B has a curved tapered surface 32c 'that protrudes gradually from the reference surface 32R of the claw member 32B and a front end surface substantially perpendicular to the reference surface 32R. 32d '.
[0020]
The label presser claw 25B is the same as a conventionally used label presser claw, and the height h2 of the label engaging portion 32b from the reference surface 32R is set to 2.0 mm. On the other hand, the label pressing claw 25A is different from the conventional one, and the height h1 of the label engaging portion 32b is set to 0.7 to 1.3 mm, preferably 0.9 to 1.1 mm. When expressed as a ratio to the height h2, the height h1 is set to 35% to 65%, preferably 45% to 55% of the height h2. The reference surface 32R is positioned so as to substantially contact the bundle of labels 100 by the operation of the adjusting screw 34 described above. Therefore, the heights h1 and h2 of the label engaging portions 32b are substantially equal to the width with which the label engaging portions 32b engage with the label 100.
[0021]
FIG. 7 shows the arrangement of the label pressing claws 25 </ b> A and 25 </ b> B in the label magazine 16. FIGS. 7A and 7B respectively show preferred arrangements of the label pressing claws 25A and 25B with respect to the rectangular label 100. In either case, the label pressing tabs 25a and 100B are arranged on the side edges 100a along the longitudinal direction of the label 100. The claw 25A is provided with a label pressing claw 25B at the edge 100b. This arrangement is because the relationship between the label pressing claws 25A and 25B and the label 100 when the label 100 is taken out is taken into consideration.
[0022]
That is, as described with reference to FIG. 1, the pallet 15 of the label applicator 1 of the present embodiment is curved along the longitudinal direction of the label 100, and is pushed onto the label 100 while swinging around the axis 15a. By applying, the label 100 is taken out from the label magazine 16. 8A to 8C show the order in which the pallet 15 contacts the label 100. FIG. As is apparent from these drawings, the pallet 15 is abutted against the label 100 from one end in the swinging direction (FIG. 8A). As the pallet 15 swings, the contact range between the pallet 15 and the label 100 gradually increases toward the other end side through the center of the label 100 (FIGS. 8B and 8C). Since the turntable 15 (see FIG. 1) rotates in synchronization with this swinging motion, the pallet 15 is gradually pulled away from the label magazine 16, and as a result, the label 100 is pulled out from the label magazine 16.
[0023]
When the label 100 is taken out in this way, at the edges 100b and 100b in the longitudinal direction of the label 100 (corresponding to the swinging direction of the pallet 15), for example, as shown in part A of FIG. 100 is turned up and removed from the claw 25B. Therefore, there is no possibility of tearing at the edge 100b of the label 100. However, with respect to the side edge 100a of the label 100, in order to avoid interference with the claw 25A, the pallet 15 is provided with recesses 15b and 15b, and the engaging portion between the claw 25A and the side edge 100a enters the recess 15b (see FIG. 8 (b)), the side edges 100a stick to the pallet 15 on both sides of the recess 15b. When the pallet 15 is separated from the label magazine 16 in this state, the force for peeling the label 100 from the pallet 15 is concentrated on the engaging portion between the claw 25A and the label 100 as shown in part B of FIG. Works. Moreover, since the pallet 15 is swinging, the peeling force acts to tear the side edge 100a of the label 100 obliquely from one end of the engaging portion with the claw 25A. For this reason, the label 100 is cut. Therefore, if the side edge 100a is locked by the label pressing claw 25A with the low label engaging portion 32b, and the end edge 100b is locked by the label pressing claw 25B with the high label engaging portion 32b, the label pressing claw 25 is It is possible to prevent the label 100 from being cut while maintaining the force for pressing the label 100 properly.
[0024]
When using an elliptical label 100 'as shown in FIG. 7 (c), it may be handled in the same manner as described above, and the side edge 100a of the label 100' has an appropriate number (two in the illustrated example) of label pressing claws. What is necessary is just to hold | suppress with 25A and hold down a part other than that with B type label pressing claw 25B.
[0025]
【The invention's effect】
As described above, according to the label magazine of the present invention and the label presser claw using the label magazine, the label can be labeled with an appropriate force by appropriately setting the height of the label engaging part of the label presser claw. While locking in the magazine, it is possible to prevent the label from being cut by limiting the resistance when the label gets over the label pressing claw to an appropriate range. Thereby, it is possible to reliably prevent tearing or twisting of the label after sticking.
