Abstract

PURPOSE:To accumulate leaves in a standing upright state without any trouble by a leaf dodging means which is protruded to the back of a fed leaf each time a leaf is fed by a leaf feed means and forms a leaf input space in a position right below a subsequent feed leaf. CONSTITUTION:Leaves 41 to which a long thin material is cut as it is fed are fed, in order, to a leaf holder 11 of a leaf accumulating means 1 by means of a leaf feed means 2, and are accumulated in a standing-upright state. A leaf dodging means 3 is protruded to the back of a leaf 41 each time the leaf 41 is fed and forms an input space for the leaf 41 in a position right below a subsequent feed leaf 41 as fall to the back (the feed side) and warp are prevented from occurring by regulating orientation of a rearmost leaf 41. This constitution inputs the leaves in an input space without interference of the subsequent leave 41 with the preceding leaf 41 and brings them into a standing- upright state. Repetition of the above motions causes proper truing of the selvages of the orderly fed leaves 41 to accumulate them in a standing-upright state.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to an apparatus for stacking continuously supplied leaves in an upright state, for example, for properly aligning leaves having an adhesive part for binding at the extreme part of the female side. The present invention relates to a stacking device suitable for stacking items while standing up.

PRIOR ART When forming a book block by cutting leaves one after another from thin long materials etc. that are continuously supplied and stacking them at a constant rate, it is often the case that the leaves are stacked in an upright position and the edges are aligned. It will be done.

In particular, when each leaf has an adhesive part on one side, and when each leaf is adhered by the adhesive part to form a book block, if the leaves are stacked flat, the adhesiveness will cause the upper surface of the preceding leaf to stick. It becomes difficult to slide the succeeding leaves and align the edges, resulting in problems such as poor i & stacking and poor alignment of the edges. For this reason, a method is adopted in which each leaf is stacked in an upright position and aligned.

Problems to be Solved by the Invention However, even when the above-mentioned leaves are fed one after another and accumulated in an upright state, the leaves may dance during feeding, or
This causes the upright leaves to warp and interfere with the subsequently supplied leaves, causing problems such as poor a-stack and poor alignment of the edges. In particular, when the leaf has an adhesive portion on one side, the adhesiveness increases the above-mentioned trouble.

The present invention provides an apparatus for stacking leaves in an upright state, which effectively solves the above problems.

Means for Solving the Problems The present invention provides an apparatus for properly stacking leaves in an upright position.
The apparatus is provided with an accumulation means having a leaf holder for accumulating leaves in an upright state, and a leaf supply means for sequentially supplying leaves to the leaf holder from an upper opening of the holder, The above-mentioned problem is solved by providing a leaf dodging means that protrudes behind each supplied leaf each time the leaf supplying means supplies leaves to form a leaf insertion space immediately below the front end of the subsequently supplied leaf. .

Further, the accumulation means may be formed of an impeller having a large number of leaf holders opening in the radial direction, and each of the leaf holders may be sequentially moved to the leaf supply position by intermittent rotation of the impeller. .

Further, the leaf supplying means can be constituted by a vacuum foil which suctions and holds the leaves on its circumferential surface and supplies the leaves to the leaf holder by rotation.

Further, the dodging means may be formed by a dodging pawl whose base end is rotatably supported, and may be arranged so that the tip of the dodging pawl projects behind the supply leaf during the rotation process.

The leaves that are cut while feeding the thin elongated material are sequentially supplied into the leaf holder of the accumulating means by the leaf supplying means and accumulated in an upright state. Each time each leaf is supplied, the above-mentioned dodging means protrudes behind the leaf and restricts the last leaf to prevent it from collapsing or warping backwards (toward the supply side), while directly placing the leaf directly below the front end of the leaf to be supplied subsequently. To form an insertion space and bring a subsequent leaf into the coterie insertion space into a standing state without interfering with the preceding leaf.

By repeating the above operations, the leaves that are supplied one after another are properly aligned and stacked upright.

EXAMPLES Hereinafter, examples of the present invention will be explained based on FIGS. 1 to 4.

The present invention provides a stacking means equipped with a leaf holder 11 for stacking four layers of leaves in an upright state, a leaf supply means 2 for sequentially supplying leaves 41 to the leaf holder 11 from an upper opening +2 of the holder 11, and A leaf dodging means 3 is provided which projects behind each supplied leaf 41 every time the leaf is supplied by the leaf supplying means 2 and forms a leaf insertion smooth S just below the front end of the leaf F & which is subsequently supplied.

The above-mentioned accumulation means 1 is an impeller 1 driven intermittently around an axis I4.
Consists of 3. For example, as shown in FIG. 4, the leaf 41 has a belt-like or dot-like adhesive 43 on one or both poles, such as the edges or the center of the leaf, as a typical example.

The impeller 13 has partitions 15 extending in the radial direction and arranged at equal intervals in the circular direction, and forming a leaf holder 11 opening in the radial direction between the partitions 15 . The leaf holder 11 has a leaf upright support surface 16 between the partition bases, which is perpendicular to the partition on each rotating side.

The partition 15 is preferably formed by arranging flat, square, or round bar shapes 7 that protrude in the radial direction at intervals in the axial direction of the impeller 13.

The impeller 13 is driven intermittently according to timing, moves each of the leaf holders 11 sequentially to the leaf supply position, receives a constant supply of leaves 41 from the leaf supply means 2, and moves the accumulator block 42 to the unloading position. do. As a means for taking out the accumulator block 4z from the leaf holder 11, an endlessly driven pusher y-9 is provided.
9 while the full bloom block 42 is stopped in a substantially flat state, the leaf upright support surface 16 of the leaf holder 11
9 towards the upper frontage 12, push the a-area surface pro 9 42 supported by the partition 15, and move outward F.
Carry it out.

The leaf supply means 2 comprises, for example, a vacuum foil 21 which holds the leaves 4 by suction on its circumferential surface and supplies the leaves to the leaf holder 11 by rotation.

The vacuum foil 21 has suction ports 22 arranged at equal intervals on its circumferential surface. Each suction port 22 communicates with a suction path 24 extending in the radial direction from the shaft portion 23, and
When it rotates near the top dead center of I, the suction passage 24 communicates with the suction source and starts sucking and adhering the leaves.When it rotates from the top dead center to near the side dead center in the direction of rotation, The same suction source is cut off and leaf adsorption is released (adsorption release point P,).
That is, the suction port 22 maintains leaf suction between the vicinity of the top dead center and the vicinity of the side dead center of the foil 21.

The thin long strip material 4 is the vacuum foil 2 that forms the leaf supply means 2! The blades are continuously fed near the top dead center of the blade, and during this time the blades are cut to a fixed size by the cutter 5 to form the holes 41 one after another. At the exit of the cutter 5, each leaf 41 is held between the endless conveyor belt 6 and the circumferential surface of the vacuum foil 21, and is transported around the same circumferential surface from just before the top dead center to just before the side dead center, and then the leaf holder 11 offered to. The endless conveyor belt 6 is a vacuum foil 2
The leaf 4 runs at the same speed and in the same direction as the leaf 21 attached to the circumferential surface from before the top dead center to before the side dead center.
Hold 1 and open the top of the leaf holder just before the side dead center! 2
The holding is released in the vicinity, and the foil 21 returns to just before the top dead center via the cutter exit side.

The suction port 22 is held by the conveyor belt 6 or -7
The front end of the leaf 41 starts suctioning near the top dead center of the vacuum foil 21, and even after it is released before the side dead center, the front end of the leaf continues to be suctioned for 11 times, and the front end of the leaf continues to attract the leaf of the leaf holder 11. The suction is released near the side dead center when the support surface 16 is reached, and the object is inserted into the holder 11.

As described above, the leaf holder 11 is formed by the partition I5 made of a pair of opposing rods 17, and the leaves 41 are sequentially accumulated in the partition 15 on the rotating side as a back-up material. In order to assist this accumulation, a first air nozzle 7 having a jetting force that is always weaker than that of the leaf suction port 22 is provided toward the back surface of the accumulated leaf, that is, the back surface of the rearmost leaf. It is arranged between the frontage weight 2 and the leaf upright support surface 16. In other words, it is disposed between the leaf open end of the conveyor belt 6 and the suction release point 22 of the suction port 22, and its ejection force presses the back surface of each leaf 41 that is successively brought in against the back surface of the already accumulated leaves.

Further, a second air nozzle 8 directed downward toward the leaf insertion portion of the upper opening 12 of the leaf holder 11 is provided. The second air nozzle 8 is located at the rear end in the feeding direction of the four leaves that have been sequentially inserted (at the top of the paddy when standing up in the leaf holder 11).
) is constantly ejected to the back surface of the leaf, and urges the leaf toward the upright support surface 16 while pressing the end of the leaf, which has been pushed toward the accumulation side by the dodging means 3, toward the accumulation side.

The dodging means 3 is formed by a dodging pawl 31 whose base end is rotatably supported. The dodging claw 31 is arranged so that the tip of the dodging claw protrudes behind the supply leaf during the rotation process, and at the time of the protrusion transition, the dodging claw 31 collects the back surface of the leaf that has been inserted at the end, preferably near the rear end of the leaf back surface. It is pushed to the side to form a space S for inserting the subsequent leaf. Therefore, this dodge claw 31
, that is, the dodging means 3 is the leaf 4 inserted at the rear end.
As a result, warping or falling down to the back side of 1 is prevented.

As a rotational driving means for the dodging claw 3I, for example, the dodging claw 31 is pivotally supported on a shaft 34 of a rotating wheel 33 such as a sprocket or a wheel, and the rotating wheel 33 is driven by a conductor 35 such as a belt or chain. By doing so, the above dodging claw 3
Obtain the rotation of I.

As a specific example of the above-mentioned dodging claw 31, as shown in FIG. 3, a leaf regulating part 36 is provided at the distal end and extends upward from the base end (toward the starting end of leaf insertion) in the protruding state, and the regulating part 36 is rotated. During the process, the vacuum foil 21 is arranged so as to protrude outward from its circumferential surface. As a result, as the foil rotates from the top dead center side to the bottom dead center direction, as shown in FIG. An insertion space S is formed directly below the front end of the leaf that is pushed to the side and subsequently supplied. At this time, dodge claw 31
By providing the regulating portion 36 of the above shape at the tip of the
An escape space 37 for the subsequent leaf is formed inside the regulating finger 36.

Although not shown, the other side of the dodging means 3 may be an eccentric cam ring in place of the dodging pawl 31, and the 10 center portion may be used as a regulating part, or the other side may be a chain or belt as shown by reference numeral 35. Endless drive! 11111' is extended to the leaf insertion position and rotated, a large number of protrusions corresponding to the dodging claws are provided at intervals on the surface of the endless drive band, and the leaf dodging work is performed with these protrusions. good.

By repeating the above-described leaf insertion operation, a constant number of leaves 41 are stacked upright in the stopped leaf holder 11, and a book block 42 is formed. When each leaf 41 has adhesive 43, each leaf 41 has 1! are attached to form a book block. This 1 m block 42 is carried to the unloading position by the intermittent rotation of the impeller I3, and the following empty leaf holder 11 is moved to the loading position and the loading operation is repeated again.

In addition, when supporting a leaf in an upright position, as long as the front end of the leaf is supported by a support surface, this includes not only a case where the leaf is supported upright but also a case where the leaf is supported in an inclined position.

The leaves that have been cut one after another from a thin elongated material according to the effects of the invention are carried into the leaf holder by a leaf supply means, such as a vacuum foil, and are inserted into the upright support surface from the upper opening of the leaf holder, thereby ensuring that the leaves are Accumulated in an upright position. At this time, the above-mentioned dodging means, for example, the dodging claw, is used to dodge the last leaf, secure a space for inserting the following leaf just below the front end, and allow the leaf to be properly inserted, raised up, and aligned. I take it. Therefore, the work of supplying leaves one after another and accumulating them in an upright state forms a constant weight block! f
This is carried out properly without causing A defects or ear alignment defects. In particular, each leaf has an adhesive part, and it can be very suitably implemented as an upright stacking means when a book block is formed by the adhesive part. That is, the accumulated I-rubble caused by the adhesive portion is reliably eliminated.
