The adhesive tape 14 is bent in a V shape in the longitudinal direction, and is linearly drawn out toward the vertical window 5a of the right-angled window 5 opening upward.

Reference numeral 17 denotes a side sticking plate having an elastic body such as rubber arranged facing the vertical window 5a of the right-angled window 5 stuck to the surface thereof.
17 is guided by a slide guide 22 horizontally mounted in the housing 1 and is attached to a tip end of a horizontal support shaft 28 which is loosely fitted to a sticking actuator 21 which is slidable toward the vertical window 5a. It is attached with a buffer spring 27 interposed.

Further, in the vicinity of the side sticking plate 17, a plate-like bottom sticking plate 23
Is horizontally projected on the sticking member 21, and a cutter 24 is provided on the lower end of the sticking member 21 below the bottom surface sticking plate 23 so that the tip of the lower surface of the vertical window 5a is desired. It is projected horizontally. Reference numeral 26 is a tension spring that constantly urges the tip of the bottom surface attachment plate 23 toward the side surface attachment plate 17 side.

Further, the sticking actuator 21 is pivotally attached integrally to the base of the bottom sticking plate 23 at the tip 20b of the swinging rod 20 which swings through a crank mechanism 19 attached to the rotary shaft of the swinging rod operating motor 18. The roller 2 is installed in the guide window 20d formed in the housing 1.
It is configured to slide by sliding 0c. The oscillating rod actuating motor 18 is configured to make one revolution by the actuation of the actuator 6a of the microswitch 6 facing the vertical window 5a.

Next, the operation of the present invention will be described. The adhesive tape reel 13 is attached to the support arm 12 whose position is adjusted by the adjusting screw 29 at the rear end of the housing 1.
Attached, and the adhesive tape 14 pulled out from this is passed through the guide rollers 15 and 16 and the knurled rollers 7 and 7'and the peeling plate
Set through 11 spaces.

Here, when the lid Aa of the predetermined box A is sealed with the adhesive tape 14, the box A is placed on the box entrance surface 4 of the housing 1 with the L-shaped sealing corner portion facing forward, When moved to the position of the step portion 3, the pair of actuators 6a, 6a of the microswitch 6 whose tip faces the vertical window 5a of the abutting surface of the right angle window 5 notched in the right angle step portion 3 are pushed, The micro switch 6 operates, the tape feed motor 9 is driven in conjunction with this, and the knurl rollers 7, 7'rotate, so that the tape peeling plate 11 reverses the V-shape from the lower edge of the knurl rollers 7, 7 '. Adhesive tape 14 sticked to the horizontal window 5b above
Is passed through and is linearly extended to the position of the vertical window 5a for a certain length.

In this case, one of the knurl rollers 7, 7'provided in series in series is constituted by a roller having a small diameter so that the number of rotations is twice as high as that of the other roller 7 '. Therefore, the adhesive surface of the adhesive tape 14 is fed toward the vertical window 5a so as to be separated from the knurled surface on the surface. Therefore, it is possible to prevent the malfunction due to the winding of the adhesive tape by the knurled roller.

On the other hand, the rocking rod actuating motor 18 is driven to make one revolution in conjunction with the micro switch 6, and in conjunction with this, the crank mechanism is engaged.
19 is rotated, and the swinging rod 20 is engaged with the tip 20b from the fulcrum 20a at the base end as a starting point, and the supporting roller 20c is rotated in the guide window 20d of the housing 1 in the left direction in the figure, The sticking actuator 21 connected to the tip 20b laterally moves toward the vertical window 5a along the slide guide 22 horizontally fixed to the housing 1. When the sticking actuator 21 is moved laterally, the side sticking plate 17 attached to the tip of the support shaft 28 that is loosely fitted to the sticking actuator 21 is repelled by the buffer spring 27 interposed and directed toward the vertical window 5a. The adhesive tape 14 that is gently pressed against the vertical window 5a is pressed against the non-adhesive back surface and is attached to the side corners of the box A that is pressed against the right angle window 5.

In this case, the adhesive tape 14 fed out has an adhesive surface on the side in contact with the knurled rollers 7, 7 ', that is, the side adhered to the box A.

At the same time that the adhesive tape 14 is adhered to the side corners of the box A, the cutter 24 horizontally installed at the lower end of the sticking actuation body 21 also moves laterally as the sticking actuation body 21 moves to the vertical window 5a. The adhesive tape 14 fed toward
Has its upper end adhered to the box A by the side sticking plate 17 and its lower end is sandwiched between the knurled roller 7 and the tape peeling plate 11 to cut the middle part thereof.

Furthermore, the adhesive tape 14 cut into a certain length is a sticking actuator.
Bottom sticking plate 23 with its base end attached to 21
By moving sideways with 21, the box A from the corner of the box A
It is attached along the bottom of the. That is, since the bottom surface sticking plate 23 is pressed at its base end by the spring 26 toward the side surface sticking plate 17 side, and the lateral movement of the sticking actuator 21 slides so that the bottom surface of the box A is pressed. The adhesive tape 14 is securely attached to the bottom of the box.

Thus, the adhesive tape 14 cut into a certain length by the cutter 24 is attached to the box A by the side attachment plate 17 and the bottom attachment plate 23 in the shape of an L-shaped corner portion on the side bottom and the bottom side. The opening angle a is sealed. In the figure, 30 indicates a preset counter for adjusting the length of the adhesive tape to be fed out.

Further, the sticking operation body 21 is moved to the return movement by the rotation of the crank mechanism 19 of the connected swinging rod 20, and the sticking operation body 21 laterally moves along the slide guide 22 and returns to the original position.

In the embodiment, an example in which a crank mechanism is used as the driving means for the sticking operation body 21 is shown. However, in addition to this, for example, a solenoid is used, and the base end of the swing rod 20 that drives the sticking operation body 21 is a solenoid. It is also possible to connect to the actuator.

<Effect of the Invention> As described above, the box sealer of the present invention forms a right angled step in the back of the box entrance surface, cuts out a right angled window, and detects the box at the position of the right angled window. Since the micro switch and the laterally movable pasting actuator that operates due to this switch are equipped with the side pasting plate, the bottom pasting plate, and the cutter, the work of pasting and sealing the adhesive tape on the box is simply the box Just place the on the box entry surface and press it to the right angle step,
Easy and reliable.

Moreover, in the present invention, the buffer spring is interposed on the support shaft on which the side sticking plate attached to the sticking actuator is loosely fitted, and the side sticking plate is buffered by the spring as the sticking actuator moves laterally. While gently moving toward the vertical window, gently press the adhesive tape toward the side corners of the box placed on the vertical window, and at the same time, the bottom attachment plate is biased by the spring at the base end. Since the tip slides along the bottom of the box and traces half of the adhesive tape that has not been attached to the bottom of the box to attach it, even if it is a soft box, it may be deformed during attachment. It is possible to attach the adhesive tape without fail.

Also, a pair of microswitch actuators that detect the box body are installed in parallel at the right-angled step, so the microswitch is not turned on unless the side surface of the box is in direct contact with the right-angled window. You can prevent wearing mistakes.

Furthermore, two knurled rollers for feeding the adhesive tape are provided in series, and one roller is compared to the other roller.
Since the number of rotations is set to be doubled, the adhesive tape is fed toward the vertical window so as to be peeled from the knurled surface on the surface, and it is possible to prevent erroneous operation due to being wound on the knurled roller side.
