Hereinafter, with reference to the accompanying drawings an example of the use of the wrapping device for wrapping paper according to an embodiment of the present invention will be described in detail.

As shown in Fig. 2 to Fig. 4, in a state where the wrapping paper 61 for displaying the expiration date or the like is seated on the bottom plate 100 under the seal type 62, the first stamp of the seal type 62 After maintaining the temperature of the heater 78 embedded in the type 62a at the set temperature (about 170 ° C.), the operation switch 77 is pressed to operate the driving motor 50 when the driving motor 50 is driven. Cam member 52 fixed to the boss (50a) mounted on the rotary shaft of the) is to cam movement.

As the upper end is connected to the cam member 52 as described above, the drive shaft 53 for converting the rotational motion of the drive motor 50 into a linear motion is lowered, so that the lifting member 59 connected to the lower end of the drive shaft 53 is interlocked with the base. It is lowered with respect to the member 51. At this time, since the elastic member 76 having the upper end fixed to the elevating member 59 is tensioned, the lever 69 is rotated clockwise around the rotating shaft. (The winding roller 68 is not rotated at this time.)

When the lifting member 59 descends, the heater block 63 fixed to the lower end of the guide rod 60 fixed to the lifting member 59 so as to be movable is lowered simultaneously. At this time, when the drive shaft 53 is lowered to the lowest position (refer to the "bottom dead center" where the cam member 52 shown in Figure 4 is located at the bottom of the boss 50a), the four corners of the heater block 63 Pressing the stamp tape 54, which is relaxed from the tape supply reel 55 by the guide roller 65 coupled to the pressure pin 64 fixedly liftable to and wound around the tape take-up reel 56, 61) Settle on.

After the seal tape 54 is seated on the wrapping paper 61 by the guide roller 65, the seal type 62 is fixed to the bottom surface by the compressive force of the elastic member 80 installed on the guide rod 60. Since the heater block 63 is pressurized, the sealing tape 54 (for example, a thin film-shaped carbon tape or the like is used) is pressed by the sealing plate which is fixed to the bottom surface of the seal type 62 and heated. 61, the expiration date of the food and the like can be displayed. At this time, since the guide roller 65 is pressed by the compressive force of the elastic member 81 coupled to the pressing pin 64 fixed to the bottom of the heater block 63, the stamp tape 54 when stamping on the wrapping paper 61 Can be prevented from flowing.

At this time, the technical information of displaying the expiration date and the like on the surface of the wrapping paper 61 by pressing the sealing tape 54 on the wrapping paper 61 by the seal type 62 having the heater 78 maintaining the set temperature, Since the technical content used in the art, detailed descriptions of their configuration and operation are omitted.

After the stamping operation is completed on the wrapping paper 61 as described above, when the drive shaft 53 due to the drive of the drive motor 50 is raised to the initial position (shown in Figure 3), the rotary shaft fixed the winding roller 68 The elevating member 59 is raised to some extent by the inclined portion 71 (for example, formed by a cam curve) formed on the cam plate 72 so as to support one end of the lever 69 which is fixed coaxially to the shaft. In this case, since the lever 69 is rotated by the restoring force of the elastic member 76, the stamp tape 54 can be wound around the tape winding reel 56 that is interlocked due to the rotation of the winding roller 68. .

Due to this, it is possible to prevent the seal tape 54 from being pulled so that the seal tape 54 is wound around the tape winding reel 56 before being completely detached from the seal tape 54 ( Conventionally, since the lever rotates immediately when the lifting member is raised while the stamping plate is pressing the stamping tape, the winding roller is rotated).

Therefore, after the seal plate of the seal type 62 is completely removed from the seal tape 54, the tape winding reel 56 connected to the take-up roller 68 by the belt 67 is rotated by the take-up roller 68. As it is rotated, the stamp tape 54 is wound from the tape supply reel 55 as long as the stamp tape 54 is wound on the tape winding reel 56 and at the same time the winding tape 54 is wound on the tape winding reel 56.

On the other hand, when lifting the seal type 62 in the vertical reciprocating motion of the elevating member 59 to seal the wrapping paper 61, the elevating piece 58 fixed to the inner surface of the elevating member 59 is the base member 51 It is supported in rolling contact with a bearing 57 mounted opposite to it. As a result, by minimizing the load generated when the elevating member 59 is elevated due to the driving of the driving motor 50, durability of the corresponding component may be improved (in the past, the LM guide when elevating the elevating member with respect to the base member). Overloading of the drive motor).

On the other hand, the elastic member 75 is coupled to the rotary shaft 73 is rotatably mounted to the elevating member 59, the tape supply reel 55 is fixed to the elevating member both ends of the band-shaped rubber plate 74 in friction contact It is possible to prevent the tape supply reel 55 from being arbitrarily relaxed by (tensile coil spring). This makes it possible to keep the tension of the stamp tape 54 relaxed from the tape supply reel 55 constant.

On the other hand, although not shown in the drawings, when the drive shaft 53 for elevating the above-mentioned lifting member 59 is reciprocated up and down, by mounting the cylinder rod of the air cylinder to the lifting member 59, the drive motor 50 The cost can be reduced by reducing the number of parts, such as the boss 50a and the cam member 52.
