The frame body 25 is set to be inclined in the direction in which the label piece 1 falls.

The mounting frame 25 is rotatable with a pivot 26 on the main body 23, and is pushed upwardly toward the rear side by the compression action of a spring 30 provided at the base 29 of the frame.

Furthermore, a microswitch SW connected to the electromagnet Mg2 of the cutting and reversing device E is set facing the frame base 29.

Further, this mounting frame 25 is provided with an actuating member 27 and a stopper 28 for receiving the label piece 1 facing the inclined lower end of the heater 24 on the back side of the pushed-up rear part. .

Next, inside the case body 23, there are provided label sticking members 44a and 44b that can be flipped up to the right and left by a link mechanism.

Specifically, a pressure-receiving member 32 is set at the position of the rotation locus of the actuating member 27 of the above-mentioned placement frame 25, and the pressure-receiving member 32 has a rotation shaft 43a fixed to which one label sticking member 44a is fixed. be.

Next, this pressure receiving member 32 is connected to a first link 34 via a fixing pin 33, and is tilted in the same direction of inclination as the mounting frame 25 by the compression action of a spring 36 provided on a pivot 35 of the first link 34. It is always pushed up.

The pivot 35 is a pivot point at one end of a pivot link 38 having a fulcrum shaft 37, and the pivot point at the other end of the pivot link 38 is the pivot 39 of the second link 40.

Further, the end of the second link 40 is connected to a driven link 42 with a fixing pin 41, and a label sticking member 4 is attached to the driven link 42.
4b is fixed, and the rotating shaft 43b is fixed.

After activation of the label, the product is pressed against the inclined placement frame 25, thereby causing the frame 25 to rotate clockwise about the pivot 26 against the spring 30.

Then, the actuating member 27 comes into contact with the pressure receiving member 32, further resists the spring 36, and pushes down the pressure receiving member 32.

Therefore, one label sticking member 44 is attached via the rotating shaft 43a.
Start lifting a counterclockwise.

In synchronization with this operation, the first link 34 is actuated in the direction of arrow 46 by the pressing down action of the pressure receiving member 32, so that the rotation link 38 is rotated counterclockwise about the fulcrum shaft 37.

Therefore, since the second link 40 operates in the direction of the arrow 47,
The other label sticking member 44b begins to flip up clockwise via the driven link 42 and the rotation shaft 43b.

By further pushing down this mounting frame 25, both of the pair of comb-shaped label sticking members 44a, 44b are lifted up as shown by the two-dot chain line in FIG. The heat-sensitive label piece placed on 44b is elastically attached to the product.

That is, label sticking members 44a+44b made of elastic material
The flip-up operation is a state in which the surface of the label piece 1 is stroked, and this label piece is attached to the product.

After pasting the label on the product, place the product on the mounting frame 25.
By removing it from the frame 25, the mounting frame 25 and the pair of labeling members 44a, 44b are returned to their original positions by the reaction of the springs 30, 36.

According to the present invention, as described above, the actuating member 27 is provided at the rotating tip of the mounting frame 25 that can be freely pushed down with respect to the case body 23 equipped with the heater 24, and the actuating member 27 is provided on the rotating locus of this member. A pressure receiving member 32 of the link mechanism is provided, and an elastic member is attached to the rotation shaft 43a or 43b of the link mechanism, faces the opening 25a and the slit 25b of the placement frame, and is disposed on the heater. Since the label sticking member 44a or 44b consisting of the label sticking member 44a or 44b is configured to be able to be flipped upward, the activated label piece present on the label sticking member can be reliably stuck to the product via the heater.

Furthermore, by using an elastic material as the flip-up type label adhesive member, it is possible to adhere closely to products exhibiting an uneven shape, which is useful for attaching this type of heat-sensitive label.

In addition, since the product is not directly bonded to the heated surface of the heater, it also has the advantage of not melting transparent vinyl packaging materials, which are often used for perishable products.
