When the inner paper 11 is fed to the falling position, one of the folded pieces 14 bordering on the fold 11a of the two-fold portion of the inner paper 11 is placed above the suction port 8 and held horizontally by suction. The other main piece 15 with the eye 11a as a boundary is made to stand diagonally upward, so the workpiece 2 falls onto the folding piece 14, and in this state the Okigami 11 workpiece 2 is folded into the inner paper. The main piece 15 is sent to the section 16 via the movement of the conveyor 7, where the main body piece 15 is bent onto the workpiece 2 by a bending plate 18 caused by a rotating member 17.

The present invention relates to a proposal for a new feeding device for the above-mentioned inner paper supply unit 10, which will be described in detail with reference to FIGS. 2, 3, and 4 below. As shown in the figure, folded pieces 21b and main body pieces 21 are formed by folds 21a in the accumulation part 20.
The inner sheets 21 with C folded in half are stacked and stored in the vertical direction with the folded pieces 21b placed at the bottom.

At this time, the two-folded part with the fold 21a as the folded part is supported by a folded part support roller 23 that is rotatable in the direction of arrow A about the pivot 22, and the main piece 21C side is the part of the stacking part 20. It is supported by the support bottom part 24, and the two-folded part is located at the open bottom surface of the accumulation part 20.

In the lower part of the stacking part 20 on the side of the support bottom 24, air is blown into the inside of the bifold part with the fold line 21a as the base, so that the folded piece 21b separates from the main piece 21C and is folded by the support roller 23. An air blowing nozzle 25 is disposed so as to hang downward with the support portion as a fulcrum, and a peeling roller 26 at the tip of the folded piece 21b is provided at the front end, and a pull-out roller 27 having the same tip is provided at the front end of the folded piece 21b. The provided advancing/retracting member 28 is disposed so as to be freely movable in the direction of the arrow.

A drive roller 29 is located at an intermediate position between the folded portion support roller 23 and the reciprocating member 28 including rollers 26 and 27.

A conveyor belt 31 is disposed obliquely downward as shown in the figure, and a support plate 32 is disposed on the back side of the belt 31 on the carrier side, and a support plate 32 is disposed on the back side of the belt 31 on the carrier side. A guide plate 33 that also slopes in parallel.
is placed.

Also, on the carrier side of the belt 31, there is a feed roller 34' which rotates in contact with the belt 31 and feeds out the inner paper 11, and a feed roller 34' is rotatably held at the tip of an arm 35 provided using a guide plate 33. It is.

In the figure, 7 is a conveyor for transporting the workpiece 2 shown in FIG. 1, 8 is its suction port, 19 is a suction air chamber, 2 is the workpiece, and 4 is the direction of the arrow R shown in FIG. 6 is a side guide member that can move forward and backward in the direction of the arrow, and a stopper 5 shown in FIG. 1 is also provided, although not shown. It is exactly the same as that of .

According to the inner paper supply device of the present invention, the bifold inner paper 21
are stacked and stored in the stacking section 20,
One sheet is taken out and supplied from the lowest inner sheet 21 in the following manner.

That is, as shown in FIG. 3 from the state shown in FIG.
The overlapping part of b and the main body piece 21C swells, and the lower folded piece 21b separates from the main body piece 21C and hangs downward using the support roller 23 as a fulcrum below the open bottom of the stacking part 20. At the same time, the advancing/retracting member 28 moves forward in the direction of the arrow, so that the tip peeling roller 26 and the pull-out roller 27 move together, and the roller 26 reliably separates the tip of the folded piece 21a downward. At the same time, the entire weight of the laminated inner paper 11 is supported by this roller 26, and the folded part support roller 23 is retracted downward as shown in the third figure, leaving the folded part of the lowermost inner paper 11 in a free state. The leading end of the folded piece 21b separated and suspended by the pull-out roller 27 is pressed against the upper end of the carrier surface of the inclined conveyance belt 31, and as the conveyance belt 31 rotates downward, the inner paper is separated from the folded piece 21b with the folded piece 21b at the beginning. 11 is sent downward by the frictional force of the belt 31.

At this time, as shown in the third figure, the folded piece 21b has already been pulled out horizontally onto the conveyor 7 in the previous step, and the main body piece 21C is attached to the conveyor belt 31 and the guide plate 3.
3, the work 2 on the mounting member 4 falls onto the folded piece 21b as the member 4 retreats in the R arrow direction, and the movement of the conveyor 7 This inner paper 11 is conveyed along with the work 2 in a direction perpendicular to the drawing, and is directed to the inner paper folding section 16 explained in FIG. 1.

At this time, the paper 21 is reliably held and transported by the conveyor 7 through the suction negative pressure generated by the suction port 8 and the suction chamber 19 of the transport conveyor 7 .

Next, as shown from the state in FIG. 3 to the state in FIG. 4, on the side of the inner paper 21 which was pulled out onto the conveyor belt 31 with the folded piece 21 b at the beginning, the tip of the folded piece 21 b was held by the arm 35. Feed roller 34 and belt 3
At the same time, the advancing and retracting member 28 retreats in the direction of the arrow, and the tip peeling roller 26 and the pull-out roller 27 also retreat together, and at the same time, the folded part support roller 23, which had been temporarily evacuated, returns to its old position. It moves back and supports the entire weight of the laminated inner paper 21.

In this way, the lowest inner sheet 21 is continuously fed downward via the guide plate 33 via the feed roller 34 and the conveyor belt 31.

At this time, on the conveyor 7, the middle paper 11 in FIG.
and the workpiece 2 have completely moved, and the carrier surface of the conveyor 7 in contact with the lower end of the conveyor belt 31 is in an empty state, while the new workpiece 2 is placed on the mounting member 4 as explained in the first diagram. As supplied.

Next, as shown in the state shown in FIG. 4 to the state shown in FIG. At the same time, the rear end of the main body piece 21C passes the feed roller 34 and is lowered until it is no longer pinched, and at this time the folded piece 21B advances onto the conveyor 7 as shown in the figure and assumes a horizontal position. When the rear end of the main body piece 21C passes the feed roller 34, the downward movement of the inner paper 21 stops, and it stands still in the unfolded posture of a dogleg shape as shown in FIG.
The workpiece 2 on the mounting member 4 will be waiting for it to fall onto the folded piece 21b on the conveyor 7 (
During this time, the conveyor belt 31 may be in a stopped state).

At this time, the position of the workpiece 2 on the mounting member 4 is regulated via the side guide member 6 and the stopper 5 shown in the first diagram, and the folded piece 21b has advanced onto the conveyor 7.
The mounting member 4
As the workpiece 2 moves backward, the workpiece 2 is dropped onto the folding piece 21b, and when the workpiece 2 falls, the placement member 4 and the side guide member 6 return to their old positions and wait for the next workpiece 2. However, when two or three works 2 are to be dropped onto the folded piece 21b and polymerized, this dropping operation may be repeated.

Thereafter, the process of taking out and supplying one sheet of the lowest inner sheet 21 is automatically repeated in the order shown in FIG. 2.3.4.

The present invention is as described above, and automatically and easily takes out the bi-folded inner paper 21 from the storage position in the stacked state one by one, starting from the lowest one, and transfers it to the workpiece 2. Excellent in terms of supply.

In this case, in the present invention, when taking out the folded part, air is blown into the folded overlapping surface of the folded part in the form of two folds to separate the lower folded piece 21b downward, and in synchronization with this. The advancing tip peeling roller 26 reliably pushes the tip outward and widens it, allowing the folded piece 21b to be separated from the main piece 21C and hang down.
The inclined conveyor belt 31 is
The inner paper 21 can be pulled out by the frictional force of the belt 31, and the inner paper 21 can be pulled out very smoothly and reliably with the folded piece 21b at the beginning.

Furthermore, the folded piece 21b pressed against the belt 31 side by the pull-out roller 27 is reliably fed out to the rear end of the main piece 21C of the inner paper 21 by the rotating feed roller 34, and the rear end of the roller 34 is By separating, the supply of the inner paper 21 is stopped, and the folded piece 21
Advancement of only b onto the conveyor 7 is easily regulated,
This facilitates superposition of the workpiece 2 onto the folded piece 21 b through the dogleg-shaped unfolding and feeding of the inner paper 21 without sending it out more than necessary, and the workpiece 2 can be easily superimposed on the folded piece 21 b under the necessary unfolded posture of the folded paper 21. Automatic take-out and supply of the inner paper 21 to the work 2 is achieved, and the efficient supply of the inner paper 21 to the work 2 allows the work 2 and the inner paper 2 to be
The present invention is excellent in that it is possible to efficiently automate the automatic packaging work with 1 and to automatically supply the inner paper 21 in a bi-folded state.
