The tape sticking and sealing device 10 is provided so that a tape reel 11 of an adhesive tape B wound in a cylindrical shape is mounted on a reel roller 12 and is rotatable. The adhesive tape B is pulled out from the tape reel 11 via the tension roller 13. The tension roller 13 is rotatably supported, and the surface thereof is knurled so that the amount of contact with the adhesive surface of the adhesive tape B becomes small and does not slip.

  A receiving plate 14 is fixed next to the tension roller 13, and a pressing plate 15 is provided for the receiving plate 14. The presser plate 15 is connected to the piston rod of the air cylinder 16 and has a structure capable of reciprocating in the orthogonal direction with respect to the receiving plate 14. The receiving plate 14 and the pressing plate 15 are configured to sandwich the pulled-out adhesive tape B, but the pressing plate 15 has a cross section so that the contacting surface is made small in order to press the adhesive tape B from the adhesive surface side. Is formed in a U-shape. Moreover, in order to suppress adhesion | attachment with the adhesion surface, it is preferable to stick the adhesive tape B to the front-end | tip part, and to make the pressure plate 15 easy to peel off.

  The tape affixing and sealing apparatus 10 is configured with a presser mechanism having such a receiving plate 14 and a presser plate 15, and a cutting mechanism having a cutting blade 17 adjacent thereto. The cutting mechanism has a structure in which the cutting blade 17 is connected to the piston rod of the air cylinder 18 and the cutting blade 17 can reciprocate so that the adhesive tape B intersects from a substantially orthogonal direction. FIG. 2 shows a state after the adhesive tape B has been cut. At this time, the cutting tip portion Ba of the adhesive tape B is free by a predetermined length. This portion becomes a grip portion for picking up the cutting tip portion Ba and pulling out the adhesive tape B.

  Accordingly, the tape sticking / sealing device 10 has a sticking mechanism for sticking the adhesive tape B to the kraft paper bag 1 as a packing member in a state where the adhesive tape B1 after being pulled out and cut is sucked and held. Is provided. The sticking mechanism is provided with a suction holding block 21 and connected to a vacuum pump (not shown) via a hose 22. The suction holding block 21 has a suction hole 21b formed in the suction surface 21a, and the cut sealing adhesive tape B1 closes the suction hole 21b, so that the sealing adhesive tape B1 is sucked by the suction of the vacuum pump. It is configured to be held by suction.

  In addition, the pasting mechanism is provided with a sandwiching plate 23 for sandwiching the cutting tip portion Ba of the adhesive tape B drawn from the tape reel 11. The clamping plate 23 is arranged so that the cutting tip Ba is pressed against the suction holding block 21 on the side far from the tape reel 11. The sandwich plate 23 that is in contact with the adhesive surface of the adhesive tape B has a U-shaped cross section so that the contact surface is small, and in order to suppress adhesion with the adhesive tape B, the adhesive tape Bx is attached to one end. , The non-adhesive surface is pressed. And the brush 24 for rubbing the attachment location of the kraft paper bag 1 is being fixed to the other end of the clamping board 23. FIG.

  The suction holding block 21 and the clamping plate 23 are integrally formed via an actuator block 25 and are slidably supported. The actuator block 25 is connected to a slider 32 attached to the guide rail 31. The slider 32 is connected to a chain 34 that is hung on a sprocket 33 that is rotated by a drive motor, and can move along the guide rail 31 as the chain 34 rotates. With such a slide mechanism, the suction holding block 21 is configured to reciprocate between the cutting / sucking position of the sealing adhesive tape B1 shown in FIG.

  The actuator block 25 includes an air cylinder that reciprocates the suction holding block 21 in a direction orthogonal to the suction surface 21a, and an air cylinder that reciprocates the air cylinder 26 that supports the clamping plate 23 in a direction parallel to the suction surface 21a. Is provided. And the clamping plate 23 connected with the air cylinder 26 becomes a structure which can reciprocate in the direction orthogonal to the adsorption | suction surface 21a.

  Then, the sticking process by the tape sticking / sealing apparatus 10 will be described. 3-9 is the top view which showed typically the tape sticking sealing device 10, and has shown the sticking process of the adhesive tape for sealing in steps. First, as shown in FIG. 3, the adhesive tape B extending from the tape reel 11 is pulled out via the tension roller 13 and is pressed between the presser plate 15 and the receiving plate 14 which are pushed out by the extension operation of the air cylinder 16. It is sandwiched. The suction holding block 21 and the clamping plate 23 are arranged at the positions shown in FIG. Specifically, it can be sandwiched between the cutting tip portion Ba of the adhesive tape B by the sandwiching plate 23 and the right end portion of the suction surface 21a of the suction holding block 21 (end portion in the pulling direction side of the adhesive tape B). Placed in position.

  Therefore, as shown in FIG. 4, the air cylinder 26 is contracted, and the tip of the clamping plate 23 is pressed against the suction surface 21 a of the suction holding block 21, and the space between the suction surface 21 a and the clamping plate 23 is pressed. The cutting tip Ba of the adhesive tape B is sandwiched between the two. Next, as shown in FIG. 5, the pressing plate 15 is retracted by the contraction operation of the air cylinder 16, and the pressed adhesive tape B is released. Then, when the slider 32 (see FIG. 2) moves to the right side of the drawing, the adhesive tape B is pulled out from the tape reel 11 with the clamping plate 23 and the suction holding block 21 holding the cutting tip Ba. The adhesive tape B is pulled out by the length of the suction surface 21a.

  Subsequently, as shown in FIG. 6, the presser plate 15 is pushed out again by the extension operation of the air cylinder 16, and the adhesive tape B is sandwiched between the receiving plate 14. Thereafter, the cutting blade 17 is protruded by the extension operation of the air cylinder 18, and the adhesive tape B is cut by intersecting from the orthogonal direction. At this time, since the suction holding block 21 is in a state where the adhesive tape B is stuck to the suction surface 21a by suction using a vacuum pump, the sealing adhesive tape B1 separated by the cutting blade 17 is sucked. The state of being stuck without being peeled off from the surface 21a is maintained. Since the cutting blade 17 is cut in accordance with the end of the suction holding block 21, the sealing adhesive tape B1 has a length substantially equal to the size of the suction holding block 21.

  Next, as shown in FIG. 7, the clamping plate 23 is separated, but the sealing tape B1 for sealing is still attached to the suction surface 21a. At this time, the clamping plate 23 is first separated from the suction surface 21 a by the extension operation of the air cylinder 26. Then, after the air cylinder 26 supporting the sandwiching plate 23 is separated from the actuator block 25 by the air cylinder in the actuator block 25, the air cylinder 26 contracts and the sandwiching plate 23 is illustrated as shown in FIG. It is arrange | positioned with respect to the pasting surface of this at the position (distant position) retreated from the adsorption surface 21a. However, the brush 24 protrudes closer to the kraft paper bag 1 than the position of the suction surface 21a.

  The kraft paper bag 1 is packed with an article 80 as shown in FIG. 1 (a), and then conveyed to the side of the tape affixing / sealing device 10 by a conveyor. As shown in FIG. The flap part 1b is formed in the part 1a, and it is folded from right and left. Then, the sealing adhesive tape B1 attached to the suction holding block 21 is attached to the folded flap portion 1b. First, as shown in FIG. 8, the slider 32 (see FIG. 2) moves to the right side of the drawing, so that the suction holding block 21 moves to the kraft paper bag 1 side. At that time, the preceding brush 24 rubs the flap portion 1b, so that the dust at the portion where the sealing adhesive tape B1 is applied is removed.

  Then, the slider 32 stops when the suction holding block 21 is positioned in front of the kraft paper bag 1, and the air cylinder in the actuator block 25 causes the suction holding block 21 to move into the kraft paper bag 1 from one direction as shown in FIG. Pressed. Thereby, the adhesive tape B1 for sealing is affixed on the right and left flap parts 1b formed in the opening part 1a of the kraft paper bag 1, and sealing is performed. Then, the suction of the vacuum pump stops, the air cylinder in the actuator block 25 contracts, and the suction holding block 21 leaves the raft paper bag 1 leaving the sealing adhesive tape B1. Thereafter, the state shown in FIG.

  According to such a tape sticking and sealing apparatus 10 of the present embodiment, the adhesive tape B is drawn straight from the tension roller 13 and cut, and is attached to the kraft paper bag 1 that is a packing member as it is. It is considered that the movement of the adhesive tape is reduced in a series of flows, and the amount of dust floating in the air is less than that of the conventional one. Also, until the sealing adhesive tape B1 is attached to the kraft paper bag 1, the entire adhesive surface of the adhesive tape B is in contact with only one location of the tension roller 13, so the adhesive of the sealing adhesive tape B1 We can prevent weakening power.

  Furthermore, according to the tape sticking / sealing device 10, since the movement of the adhesive tape until it is attached to the kraft paper bag 1 is small as described above, the entire device can be configured compactly. Moreover, since the adhesive tape B1 for sealing is simply pasted against the kraft paper bag 1, the structure of the tape affixing / sealing device 10 is simplified, and in this respect as well, the entire device is made compact. Is possible. In addition, since the brush 24 removes dust from the sealed portion of the kraft paper bag 1, the adhesion of the sealing adhesive tape B1 can be improved.

As mentioned above, although embodiment was described about the tape sticking sealing apparatus of this invention, this invention is not necessarily limited to this, A various change is possible in the range which does not deviate from the meaning.
For example, in the above embodiment, the tension roller 13 is configured to contact the adhesive surface side of the adhesive tape B. However, the positions of the reel roller 12 and the tension roller 13 are changed, and the adhesive tape B pulled out from the tape reel 11 is used. The tension roller 13 may be in contact with the non-bonding surface side.
Further, although the air cylinder is used as each actuator for operating the presser plate 15, the cutting blade 17, the suction holding block 21, and the clamping plate 23, an electric cylinder or the like may be used.
