Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for feeding individual sheets of breathable sheets, which could not be properly fed using the conventional paper feeding method using a vacuum, when feeding special sheets with breathability such as non-woven fabrics used in printing etc. Regarding a paper feeding device using an adhesive tape that was developed so that paper can be appropriately fed in the feeding direction of each sheet through the adhesive tape, in particular, the downward pressure of the adhesive blade is kept elastic, and the bottom surface of the blade is The reason is that it is configured so that it is always parallel to the sheet.

Normally, paper is fed to the printing machine using the vacuum method, but the paper feeding sheet is made of a breathable sheet such as porous Japanese paper, porous Western paper, cloth, or the surface has been treated with a montre-like fuzzy texture. In the case of sheets, the current situation is that the paper cannot be fed using the vacuum method, and in this case, the actual situation is that one sheet is fed manually.

In addition, when feeding the above-mentioned breathable sheets using the vacuum method, conventionally the breathable sheet is lined with a non-breathable sheet and used for printing, and the backing paper is peeled off after printing. be.

Therefore, carrying out such lining work brings about many disadvantages, such as a rise in material costs, an accompanying increase in work costs, and loss of time.

The present invention eliminates such drawbacks in view of the above-mentioned conventional examples, makes it possible to appropriately feed a breathable sheet that could not be fed using the vacuum method, and allows paper feeding to be performed in sheets when printing on a breathable sheet made of non-woven fabric or the like. In addition to being able to properly feed each sheet as it is through the adhesive tape, it is also possible to achieve stable engagement between the blade that adhesively holds the sheet and the sheet. An example will be described.

In FIG. 1, reference numeral 1 denotes a breathable sheet made of a non-woven fabric or the like made of a suitable number of sheets, and 2 a paper feeding device disposed opposite to the upper surface of the sheet.

The paper feeding device 2 schematically includes a first paper feeding section 2 having an adhesive blade 4 for drawing out the adhesive tape 3.
a, and a second paper feed section 2b having a brush 5 whose directionality is maintained, and the first paper feed section 2a and the second paper feed section 2b are shown in FIG. 4 in correspondence with each other in the width direction. They are arranged oppositely at a predetermined interval.

The first paper feed section 2a includes an adhesive blade 4 having a pressing surface for press-bonding the adhesive surface of the adhesive tape 3, which is sequentially fed out from one reel 6 toward the other reel 6', to one surface of the sheet. , a rod 7 for abutting or floating the adhesive blade against one surface of the sheet, a movable frame 8, a connecting rod 9 for vertically moving the movable frame, a movable frame 10 opposite to the side surface of the movable frame 8, Movable frame 8
and a pivot 11 that connects the movable frame 10, an adhesive tape feed lever 13 that is arranged on the movable frame 10 and rotates by collision with the opposing stopper 12, and the adhesive blade 4 is further connected to the movable frame 8.
It is attached smoothly to the

In the above, the adhesive blade 4 is allowed to slide vertically along the inclined groove 14 provided between the movable frame 10 and the movable frame 8 side,
A pin 15 protruding from the adhesive blade 4 engages with a slot 16 formed in the movable frame 10 to prevent the adhesive blade 4 from falling.

On the other hand, the stopper 12 and the movable frame 1
The stopper 17 that collides with the rear end of the upper surface of
a and a movable arm 20b pivotally connected to the shaft, and a spring 21 is attached to the movable arm 20b via a bracket 22 for applying a downward pressure to the movable arm 20b.

Note that 13a is a stopper that regulates the lowering position of the feed lever 13 attached to the movable frame 10 and the movable frame 10 itself, and prevents the feed lever 13 from rotating when pushed up by the spring 13b, and prevents the movable frame 10 from moving by the spring 10a.
23 is a backing plate that is in contact with the upper surface of the rear end of the seat 1;
Reference numeral 24 denotes a blower foot located at the upper part of the rear end side of the seat 1.

The second paper feed section 2b consists of movable arms 26, 27, 27' driven by opposing cams 25, and a directional brush 5 provided at the tip of a bracket 28 held by the movable arms. The brush 5 includes a vacuum mechanism 5a for pressing the brush against the sheet 1 surface with a constant pressure, and an air blower for preventing the sheet 1 from being inserted twice by making the brush 5 slide well between the lower sheets. It consists of a mechanism 5b.

Therefore, in the second paper feeding section 2b, when the cam 25 rotates clockwise in the drawing, the movable arm 27 first moves to the support shaft 2.
The brush 5 is moved back and forth by a follow-up mechanism in which the movable arm 26 rotates to the right around the support shaft 26a, and then by a follow-up mechanism in which the movable arm 26 rotates to the left around the support shaft 26a.

In the above, the rotation of the cam 25 is
This is done in conjunction with the operation of the connecting rod 9 on the a side, and 2
Reference numeral 9 denotes a transfer roller for forcibly sending the sheet 1 fed out a predetermined distance by the second paper feeding section 2b to the supply side of a printing machine or the like.

Next, to explain the operation of the present invention, the adhesive tape 3 is fed out from the lower surface of the adhesive blade 4 with the adhesive surface facing the sheet side, and as the connecting rod 9 descends, the adhesive blade 4 is moved as shown in FIG. It is pressed against one side of the sheet.

Here, the adhesive blade 4 is simply brought into contact with the sheet 1 surface by the downward pressure of the connecting rod 9.

Therefore, the adhesion pressure of the adhesive blade 4 to the sheet surface is such that even though the upper surface of the sheet fluctuates in horizontal position with an unbalanced element due to the lower table lifter, appropriate adhesion can be achieved with the above-mentioned cushioning elastic pressure. . Note that the adhesive blade 4 is attached to the blade holder 4' as shown in FIG.
The portion may be made of an elastic material for cushioning purposes.

In the vertical movement of the movable frame 9, as the movable frame 8 rises in parallel, the movable frame 10 also rises until it comes into contact with the stopper 17, and the movable frame after colliding with the stopper 17 10 makes a tilting motion to gradually pull up the reel 6 side by the rising action of the pivot 11, and with this tilting motion, the adhesive blade 4
is pushed diagonally forward along the inclined groove 14 of the movable frame 8 by engagement with the pin 15 and the groove hole 16.

Therefore, the adhesive blade 4 is not simply raised, but is pushed forward while facing the sheet 1 by the upward slope of the movable frame 10.
Sheet 1 lifted upward by adhesive blade 4
It is easy to pass under the footboard 23 and the footboard 24,
Moreover, the sheet 1 can be fed out in the supply direction.

On the other hand, when the movable frame 10 rises to a predetermined position, the feed lever 13 collides with the stopper 12 and rotates clockwise by a predetermined amount, preparing to wind up the adhesive tape 3 by a predetermined amount.

Note that the backing plate 23 serves to prevent the second sheet from being pulled up in an adhesive manner with respect to the first sheet 1 pulled up by the adhesive blade 4, and the blower foot 24 blows the air released from this into one sheet. It is sent between the first and second sheets to separate the two sheets appropriately.

In response to the above-mentioned operation of the first paper feed section 2a, the second paper feed section 2b operates in synchronization with this, and the brush 5 is moved in front of the sheet 1 for the sheet 1 pulled up by the adhesive blade 4. The surface of the brush 5 is pressed against the sheet 1 by the vacuum mechanism 5a, and when the first sheet feeding section 2a is lowered, the brush 5 is pressed against the sheet 1 by the operation of the second sheet feeding section 2b. 1 is sent out to the transfer roller 29 side while sliding from the second sheet.

In this way, the sheet 1 held by the adhesive blade 4 is released from the adhesive blade 4 by being sent out by the brush 5 when the adhesive blade 4 is lowered, and the sheet is thereafter carried out by the transfer roller 29. Note that the air blowing mechanism 5b is for creating an air layer between the first and second sheets to improve separation between them, and the brush 5 is for making use of the air permeability of the sheet 1. The air serves to prevent the second sheet from coming into contact with the brush 5 side.

When the first paper feed section 2a descends, the feed lever 13 separates from the stopper 12 and rotates back to a predetermined position by the spring 13b, and as the reel 6' rotates due to this return rotation, a new adhesive surface is created under the adhesive blade 4. It is fed out and used for pulling up the next sheet (see Figure 1). Further, after the sheet 1 is held by the transfer roller 29, the second sheet feeding section 2b also returns to the position shown in FIG. 1 via a return spring (not shown), completing one cycle of the sheet feeding process. .

Incidentally, after the above cycle is completed, the blower foot 24 also returns upward, and at this timing, although not shown in the figure, the pallet on which the sheets 1 are stacked can rise slightly via a micro switch, and the pallet carrying the sheets 1 to be supplied can rise slightly. The top surface always remains in the same position.

The present invention is constructed as described above, and even if the paper feeding sheet is a breathable sheet such as a non-woven fabric, the paper feeding can be carried out appropriately by progressively lifting the adhesive blade 4 of the first paper feeding section 2a by sliding it upward. Sheet 1
Taking out each sheet and the brush 5 of the second paper feed section 2b
By properly feeding each sheet by the air blowing mechanism 5b, it is possible to easily and reliably feed two sheets without causing the disadvantages of two-sheet feeding. When the adhesive blade 4 is tilted in the direction, the inclined groove 14
The adhesive blade moves diagonally upward in the paper feeding direction with the bottom facing toward the paper feed sheet, and the adhesive blade moves diagonally upward in the paper feeding direction compared to the case where the adhesive blade is fixed to a movable frame and moves in an arc. It can be moved widely in the paper direction, and the sheet lifted by the adhesive blade 4 can be reliably moved in the paper feeding direction without getting caught in the front end of the blower foot. Then,
Even if the paper feeding sheet is a thin sheet with a small basis weight, it can be fed very appropriately without causing double sheet feeding, and for those involved in paper feeding work, it can relieve the stress of paper feeding work and the paper feeding work. This can greatly contribute to labor saving and elimination of wasted sheet loss seen in paper feeding losses. Note that the paper feeding device 2 consisting of the first paper feeding section 2a and the second paper feeding section 2b actually feeds both areas of the paper feeding sheet 1 around the blowing foot 24 as shown in FIG. It has been set up.

The present invention provides a movable frame that moves in a direction perpendicular to the surface of the paper feed sheet, and a movable frame that has an adhesive tape on the lower surface that is in contact with the surface of the paper feed sheet that has air permeability. The adhesive blade is disposed between a tilting movable frame that is pivotally connected and can tilt upwards on the paper feeding sheet surface, and the adhesive blade is equipped with a pin that engages with the tilting movable frame, so that it follows the tilting movable frame and tilts upward. Since the movable frame is provided with a slanted groove that guides the adhesive blade that moves diagonally upward in the paper feeding direction, when the movable slanting frame rotates and tilts the paper feeding sheet upward, the slanted groove This allows the adhesive blade to move diagonally upward in the paper feeding direction with the adhesive blade facing toward the paper feeding sheet, allowing for greater movement of the adhesive blade in the paper feeding direction, ensuring that the sheet lifted by the adhesive blade is moved in the paper feeding direction. It has the advantage of being able to be moved.
