Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag mouth and a box lid,
Also, the present invention relates to an adhesive tape cutter with a tip bending mechanism for forming a non-adhesive portion for facilitating peeling at an end of the adhesive tape for sealing a bundle of loose materials.

[0002]

2. Description of the Related Art A non-adhesive portion provided at an end of an adhesive tape is used as a hole for opening a lid of a box sealed with the adhesive tape.

As an adhesive tape cutter device for forming such a non-adhesive portion, another tape for forming the non-adhesive portion is set in addition to the adhesive tape, and the tape for forming the non-adhesive portion is attached to the end of the adhesive tape by a predetermined length. There are known a type of feeding and sticking, and a type in which a paint foil tape is incorporated and set and a predetermined width of foil is stamped on an end of the adhesive tape.

However, such an adhesive tape cutter device requires a space for incorporating a tape for forming a non-adhesive portion or a paint foil tape, which not only hinders miniaturization of the device but also cuts the device. In addition, the mechanism of feeding and the like becomes complicated, and the necessity of a separate tape hinders cost reduction.

Accordingly, the present applicant has filed a Japanese Patent Application No. Hei 4-3268.
No. 0 (registered No. 2532027) proposes an adhesive tape cutter with a tip bending mechanism.

In this method, a tape bending veneer for bending an adhesive tape and a hammer-type two-fold body for folding the curved portion into two parts are provided at a position preceding the cutting position where the tape is cut at a predetermined length. A part (tip portion) of the tape itself is directly folded into two to form a non-adhesive portion, thereby easily obtaining a mouthpiece for sealing, bundling, and the like.

[0007]

However, in the above-mentioned conventional adhesive tape cutter with a tip bending mechanism, a first motor for feeding the adhesive tape and a swinging motor for bending the tape end are used. Since a second motor for swinging the arm is required, an installation space for incorporating these motors is required, which hinders further miniaturization of the apparatus.

[0008] In addition, when the characteristics of the first and second motors vary due to aging, the timing of sending the adhesive tape by the first motor and the timing of the bending process by the second motor are considered. There is a possibility that a shift may occur.

Further, when the tape end is bent, the tape tip is vertically pushed up by the tape bending plate, and the tape tip is bent in the vertical direction. Since the tape ejection port has a slightly upward habit, the bent portion may be caught by the tape ejection port when the tape ejection port is narrowed.

Further, since the power for performing the bending process of the tape end and the like is performed in conjunction with the movement of the elevating slide plate which performs the elevating operation by the swing of the swing arm, the respective linking operations are performed. If there is a slight deviation, a series of operations may not be performed reliably.

The present invention has been made in view of such circumstances, and has as its object to provide an adhesive tape cutter with a tip bending mechanism capable of reducing the size and improving the reliability of the apparatus.

The cutter 10 having such a structure performs the following operation. First, when attaching the tape body 151 to the cutter body 11, the cover body 50 of the cutter body 11 is opened to expose the adhesive tape reel 100 as shown in FIG.

In this state, the central portion of the tape body 151 is fitted to the reel body 110. Next, the end of the adhesive tape 150 of the tape body 151 is pulled out from the tape body 151,
After the adhesive tape 150 is engaged with the lower surface of the tape receiving roller 210 with the adhesive surface of the adhesive tape 150 facing down, the adhesive surface of the adhesive tape 150 is engaged with the tape feed roller 220.

Further, the end of the adhesive tape 150 is inserted between the tape feed belt 230 and the pressing roller 250,
The drive pulley 240 is rotated counterclockwise while the adhesive surface of the end of the adhesive tape 150 is adhered to the surface of the tape feed belt 230. Thereby, the adhesive tape 150 is sent out to the tape end processing mechanism 300 side as the tape feed belt 230 rotates. At this time, the adhesive tape 1
50 is sent out while being pressed against the tape forming groove 231 by the tape forming piece 260.

At this time, the adhesive tape 150 is pressed by the tape-curling piece 260 into the tape-curling groove 231 so that the tape is curled. The waist is held. For this reason, the end of the adhesive tape 150 sent out by the tape feed belt 230 is connected to the tape end processing mechanism 3.
After passing through 00, it can be smoothly fed out from the discharge port 13 shown in FIG. Thus, the mounting of the tape body 151 is completed.

When using the adhesive tape 150, first, a power switch (not shown) is turned on. here,
When using in the manual mode (a mode in which the tape length is arbitrarily set), the mode switch is set to the manual mode.

On the other hand, when using in the auto mode, the mode changeover switch is set to the auto mode side. At this time, the feed length, which is the used length of the tape, is set by the setting unit.

When the feed switch is pressed, the drive motor 201 of the tape feed mechanism 200 is driven. When the drive shaft 202 rotates clockwise in FIG. 2 by the drive of the drive motor 201, the clutch mechanism 20
By the operation of 3, only the driving gear 205 is rotated, and the driving force is transmitted to the receiving gear 702 attached to the shaft 703 via the chain belt 701 meshing with the driving gear 205.

With the rotation of the shaft 703, the drive pulley 240 attached to the rotation shaft 242 in FIG. 1 rotates, and the tape feed belt 230 rotates counterclockwise.
At this time, the tape feed roller 220 is connected to the shaft 703 described above.
By receiving a driving force from a rotating shaft 242 disposed coaxially with the shaft through a chain belt (not shown), the rotation is performed, and the adhesive tape 150 is pulled out from the tape body 151.

Here, in the manual mode, it is confirmed that the adhesive tape 150 has been sent out of a desired length from the discharge port 13, and when the finger is released from the feed switch, the drive of the drive motor 201 starts rotating clockwise. The rotation is switched to counterclockwise.

As a result, in FIG. 2, the drive gears 204 and 205 are rotated by the action of the clutch mechanism 203, and the chain belt 801 meshed with the drive gear 204.
Is transmitted to the receiving gear 802 via the
The cam mechanism 800 is rotated counterclockwise.

The rotation of the cam mechanism 800 causes the cutter mechanism 400, the folding mechanism 500, and the bending mechanism 600 to rotate.
Perform predetermined operations sequentially.

That is, first rotation of the first cam 820 in the counterclockwise direction causes the miniature bearing 861 attached to the lower end of the drive shaft 860 to be rotated by the second cam surface 822 as shown in FIG. By being shifted upward, the drive shaft 860 is pushed up.

With the upward movement of the drive shaft 860, for example, as shown in FIGS. 3 and 8, the link arm 440 rotatably connected via the connection shaft 445 resists the urging force of the coil spring 450. It rotates counterclockwise about the shaft 443 as a fulcrum.

As a result, the drive pin 442 on one end 441 of the link arm 440 is
22 to apply a downward pressing force to the cutter blade 42.
Decrease 0 gradually.

Then, as shown in FIG. 4, for example, when the cutting edge 421 of the cutter blade 420 is lowered to the vicinity of the tape receiving piece 14 provided near the tape discharge port 13,
The adhesive tape 150 is cut. At this time, the temporary holding surface 433 on the lower surface side of the temporary holding piece portion 432 comes into contact with the tape receiving piece 14 provided in the discharge port 13, and the adhesive surface of the adhesive tape 150 is attached to the tape receiving piece 14. Thus, an appropriate tension is applied to the cut portion of the adhesive tape 150, so that the cutting by the cutter blade 420 is performed smoothly. In addition, the cut adhesive tape 15
0 is separated from the rear adhesive tape 150 while being attached to the tape receiving piece 14, so that the cut adhesive tape 150 can be easily grasped.

At this time, as shown in FIG. 7, for example, the small roller 871 is connected to the second cam surface 832 of the second cam 830.
9, the connecting lever 873 is pushed rightward in the figure by the urging force of the coil spring 874, and the driving member 870 rotates clockwise via the shaft 872, as shown in FIG. I do.

With the movement of the connecting lever 873, a folding piece 513 made of resin is provided via the support arms 510 and 511 rotatably connected to the end of the connecting lever 873 via a rotating shaft 512. Rotates in the tape ejection direction.

At this time, for example, in FIG. 10, since the small roller 843 is shifted downward by the second cam surface 842, the frame 610 is pushed downward.

With the downward movement of the frame 610, the engaging pin 621 of the rotation support member 620 provided in the middle of the frame 610 is moved to the elongated hole 7 on the side surface of the second internal chassis 70.
Descend along 2 When the movement is restricted by contacting the lower end of the long hole 72, the miniature bearing 6
The rotation support member 620 rotates by retracting into the escape hole 611 while rotating. By this rotation, the bending piece 624 gradually turns to a horizontal state in which the pressing surface 623 side is upward.

As a result, the tip end of the adhesive tape 150 cut by the cutter blade 420 is folded back by a predetermined amount toward the folding piece 513 of the folding mechanism 500 with the adhesive surface side inside.

Further, in the present embodiment, the timing of cutting the adhesive tape 150 by the cutter mechanism 400 is given by the first cam 820, and the folding mechanism 5
Since the folding process timing of the cut portion by 00 is given by the second cam 830 and the folding process timing of the folding portion by the folding mechanism 600 is given by the third cam 840, the linkage operation of these various processes is shifted. A series of operations are reliably performed without any occurrence.

In the present embodiment, the first cam 82
When the link arm 440 swings by the rotation of 0 and the cutter blade 420 is lowered, the tape temporary holding piece 430 is moved.
The temporary holding piece portion 432 abuts on the tape receiving piece 14 provided in the discharge port 13 and sticks the adhesive surface of the adhesive tape 150 to the tape receiving piece 14, so that a proper tension is applied to the cut portion of the adhesive tape 150. Is provided, the cutting of the adhesive tape 150 by the cutter blade 420 is performed smoothly.

Further, in the present embodiment, the second cam 8
When the connecting lever 973 performs a horizontal operation by the rotation of the rotation of the lever 30, the folding piece portion 513 is moved in conjunction with this operation, and
In order to fit into the folded portion of the adhesive tape 150 which is being bent by the adhesive tape 150, the adhesive tape 1
The bent end of the adhesive tape 150 is not attached to the discharge port 1
3 can be discharged smoothly.

Further, in the present embodiment, when the frame 610 is lowered to a predetermined position by the rotation of the third cam 840, the bent piece 624 is rotated, and the pressing surface 623 is moved to the vicinity of the inside of the discharge port 13. The adhesive tape 150 is brought into contact with the fixed receiving surface 513 provided in a horizontal state from below.
Since the folded part of the cut part is bent, the adhesive tape 1
50 can be bent along the direction in which the adhesive tape 150 is fed out.
The 50 bent ends can be smoothly discharged from the discharge port 13.
