Detailed Description of the Invention

[Industrial applications]

The present invention cuts a marking tape (mark tape) into a predetermined length between sheets such as sheets to be stacked,
Alternatively, a mark tape inserter for inserting in a continuous multi-stage pleated shape without cutting, particularly, a tape held on a reel is fed by a tape feeding mechanism and guided by a tape guide and provided at the tip thereof. The present invention relates to a mark tape inserter that is inserted between sheets from a discharge port of a cutter block.

[Prior art]

An example of such a mark tape inserter is,
The one disclosed in Japanese Patent Laid-Open No. 103658 is conventionally known. This is because a flexible long sheet is slidably fitted in the tape guide, and when the tape is not cut, this long sheet is pushed out from the tip of the tape guide together with the tape under the tape, The tape is pushed by the tip of this long sheet to form a fold, and the tape is formed into a continuous multi-stage pleated shape and is inserted between the sheets. Also, when cutting the tape, the long sheet is retracted.

[Problems to be Solved by the Invention]

However, according to this, when inserting without cutting the tape, the tape is pushed by the end of the long sheet, so that even if the tape can be accurately fed to the uppermost surface of the stack of sheets, the long sheet can be fed. The tape may come off the sheet as the sheet retracts. Also, when cutting the tape to a specified length and inserting it between the sheets, the tip of the tape is completely released and becomes free, and the sheet falls on it, If the carp curls because of the remaining curl,
There are problems such as an insertion error and the tape falling off due to the wind from the sheets falling. An object of the present invention is to solve such a problem, that is, when a tape is cut and inserted, it can be accurately inserted even if the tape is curled, and a continuous multi-stage pleated shape is formed without cutting. It is an object of the present invention to provide a mark tape inserter that can fold a tape and insert it properly at a predetermined position even when it is inserted by using the mark tape inserter.

[Means for Solving the Problems]

In the mark tape inserter according to the present invention, the tape held on the reel 3 is fed by the tape feeding mechanism, guided by the tape guide 4, and the cutter block 5 provided at the tip thereof.
The guide tape 17 is a mark tape inserter for feeding between stacked sheets from the discharge port 10 of the above, and a guide plate 17 is hinged to the cutter block 5 above the discharge port 10 by a hinge 19 so as to be vertically rotatable. A sheet receiving plate 15 is slidably mounted on the seat 17 so as to be slidable forward and backward, and the rear end of the sheet receiving plate 15 is moved forward and backward so that the piston rod 14
Is connected to the tip of the via a connecting fitting 16. Further, below the discharge port 10 of the cutter block 5, there is provided a pleated plate 20 which is formed into a continuous multi-stage pleated shape and which holds the folds of the tape to be inserted between the stacked sheets.

[Action]

Before sending out the tape, the sheet receiving plate 15 is advanced by the air cylinder 13 while being guided by the guide plate 17 to a position above the uppermost surface of the stacked sheets, and the sheet receiving plate 15 catches the falling sheet while the tape is being received. When the required number of sheets are stacked on the sheet receiving plate 15, the sheet receiving plate 15 is retracted, the required number of sheets are newly stacked and the tape is sandwiched, and then the tape is removed. When cut, the cut tape pieces are properly inserted into a predetermined stacking position. In this case, since the height of the tape discharged from the discharge port 10 of the cutter block 5 is lower than that of the sheet receiving plate 15, even if the tape is curled upward, the tape is pressed by the sheet receiving plate 15 and guided there. While being conveyed, the sheet is fed below the sheet that is temporarily received by the sheet receiving plate 15. If you insert the tape in multiple continuous pleats without cutting it, advance the sheet receiving plate 15 to above the uppermost surface of the stacked sheets before feeding the tape, and remove the falling sheets. When the tape is sent to the lower side of the sheet receiving plate 15 while receiving it by 15, the tape is meandered between this sheet receiving plate 15 and the uppermost surface of the stack of sheets, and when the required number of sheets are stacked on the sheet receiving plate 15. When the sheet receiving plate 15 is retracted, the meandering tape is folded and accurately inserted into a predetermined stacking position as the required number of sheets are newly stacked. In this case, since the pleating plate 20 is vertically provided below the discharge port 10 of the cutter block 5, the pleating plate 20 can press the tape to form the pleats of a certain size accurately. . The sheet receiving plate 15 is penetratingly attached to the guide plate 17 at the discharge port 10 of the cutter block 5 so as to be slidable back and forth.
Since 17 is hinged to the cutter block 5 by a hinge 19 so as to be vertically rotatable, and the rear end of the sheet receiving plate 15 is connected to the tip of the piston rod 14 of the air cylinder 13 via a connecting fitting 16. When changing the vertical inclination of the sheet receiving plate 15, the guide plate 17 is removed from the cutter block 5 by changing the installation height of the air cylinder 13 itself or the height of the rear end of the sheet receiving plate 15 by the connecting fitting 16. It is possible to deal with the sheet receiving plate 15 in a state where the sheet receiving plate 15 is inserted through the guide plate 17 without being installed.

【Example】

An embodiment of the present invention will be described in detail below with reference to the drawings. 1 to 3, a reel 3 is slidably installed on a rear side of a main body 1 incorporating a known tape feeding mechanism, a cutter driving source, etc., and a main body 1
A tape guide 4 having a sheath shape is horizontally projected on the front side of the tape guide, and a cutter block 5 containing a rotary cutter is fixed to the tip of the tape guide 4. This rotary cutter has a lever 6, a link rod 7, fixed to one end thereof,
Main body 1 via disc crank 8 and link rod 9
Is connected to the cutter driving source in the inside. The winding tape T held on the reel 3 passes through the inside of the main body 1 and straightly penetrates through the tape guide 4, and is fed by the tape feeding mechanism inside the main body 1 to be discharged from the discharge port 10 on the front surface of the cutter block 5. Is discharged. A pair of short columns 11 are erected and fixed to the middle portion of the tape guide 4, and a cylinder holder 12 is screwed to these columns 11 so that the height of the cylinder holder 12 can be adjusted. And this cylinder holder
An air cylinder 13 is installed between 12 and the main body 1. At the tip of the piston rod 14 of this air cylinder 13, the rear end of the elongated sheet receiving plate 15 is an L-shaped connecting fitting 16
Are connected by. This sheet receiving plate 15 is a guide plate
A guide groove (not shown) formed in the upper surface of 17 is penetrated so as to be slidable back and forth, and is pressed by a lid plate 18 from the upper side so as not to come off the guide groove. The guide plate 17 is hinged to the cutter block 5 by a hinge 19 so as to be rotatable up and down, and the height of the cylinder holder 12 is adjusted to change the installation height of the air cylinder 13 itself, or the seat by the connecting fitting 16 is used. By changing the height of the rear end of the receiving plate 15, without removing the guide plate 17 from the cutter block 5, the sheet receiving plate 15 can be vertically attached to the upper and lower sides of the sheet receiving plate 15 while the sheet receiving plate 15 is inserted through the guide plate 17. The tilt of can be adjusted. Further, an inverted L-shaped pleat press plate 20 is detachably attached to the lower surface of the cutter block 5 with a set screw 21. Its mounting position can be adjusted back and forth. Next, the operation of this mark tape inserter will be described. FIG. 4 shows a case where the tape T is cut and inserted between the stacked sheets P as a tape piece T ′ having a predetermined length from the side. In this case, the sheet receiving plate 15 is moved forward by the air cylinder 13, the sheet receiving plate 15 is positioned slightly above the uppermost surface of the sheets P ′ already stacked, and then the sheet receiving plate 15 is sequentially dropped. While receiving the sheet P by the sheet receiving plate 15, the tape T is fed by a predetermined length and discharged from the discharge port 10 of the cutter block 5. At this time, since the ejection height of the tape T is lower than that of the sheet receiving plate 15, even if the tape T curls upward, the sheet T is pressed by the sheet receiving plate 15 and falls. The sheet P is separated from the sheet P, and is reliably inserted between the sheet P stacked on the sheet receiving plate 15 and the uppermost surface of the sheet P ′ already stacked. When the required number of sheets P are stacked on the sheet receiving plate 15, the air cylinder 13 is returned to operate to retract the sheet receiving plate 15, and then the cutter driving source is operated to cut the tape T with the rotary cutter. , Tape T is sheet receiving plate 15
The sheet P is pressed by a required number of sheets P which are separated from the top and newly stacked at the same time, and the sheet P is cut after being sandwiched between the required number of sheets P and the uppermost surface of the already stacked sheets P '. Therefore, the cut tape piece T '
Is reliably inserted between these sheets P, P '. FIG. 5 shows a case where the tape T is inserted into a continuous multistage pleated shape without cutting. In this case, the sheet receiving plate 15 is advanced by the air cylinder 13 in the same manner as above, and the tape T is fed by a predetermined length while receiving the sheets P that are sequentially falling by the sheet receiving plate 15. When the tape T is ejected from the ejection port 10 of the cutter block 5,
The sheet P'is meandering between the uppermost surface of the already stacked sheets P'and the sheet receiving plate 15. Therefore, when the air cylinder 13 is returned to the original position and the sheet receiving plate 15 is retracted, the meandering portion of the tape T is pushed away by the required number of sheets P which are separated from the sheet receiving plate 15 and are stacked at the same time. The required number of sheets P and the uppermost surface of the already stacked sheets P ′ are sandwiched and folded, and a part of them is not sandwiched to form a fold-shaped portion Ta, which protrudes from the sheets P ′. At this time, since the vertical portion of the pleat pressing plate 20 hangs from the lower side of the cutter block 5, the pleat-shaped portion Ta is prevented from swelling more than a predetermined amount by the pleat pressing plate 20. And the tape T tends to be placed on the uppermost surface of the sheets P ′ already stacked. The size of the pleated portion Ta can be adjusted by adjusting the mounting position of the pleated plate 20 with respect to the cutter block 5 back and forth. Although one embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications and applications are possible without departing from the basic idea thereof.

【The invention's effect】

According to the present invention, the sheet receiving plate is slidably attached to the guide plate provided on the upper side of the discharge port of the cutter block and is moved forward and backward by the air cylinder. While advancing to the uppermost surface of the stack of sheets while guiding with the guide plate, the tape is sent to the lower side of the sheet receiving plate while the falling sheet is received by this sheet receiving plate, and the tape is curled upward. If the tape is curled, it will be fed below the sheet that was temporarily received by this sheet receiving plate while pressing and guiding the tape with the sheet receiving plate. It can be inserted, and even when it is inserted in a continuous multi-stage pleated shape without cutting, it can be inserted accurately at a predetermined position. Also, when inserting the tape in a pleated shape without cutting it, the pleating plate is hung vertically below the discharge port of the cutter block. Sano folds can be formed accurately. Further, the sheet receiving plate is mounted on the upper side of the discharge port of the cutter block so as to be slidable back and forth on the guide plate, and the guide plate is hinged to the cutter block by a hinge so that the sheet receiving plate can be rotated up and down. The rear end is connected to the tip of the piston rod of the air cylinder via a connecting metal fitting, so when changing the up and down inclination of the sheet receiving plate, the installation height of the air cylinder itself or the sheet receiving plate of the connecting metal fitting should be used. By changing the height of the rear end, it is possible to cope with the sheet receiving plate being inserted through the guide plate without removing the guide plate from the cutter block.
