DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a steel sheet laminated in a rectangular shape,
The present invention relates to a paper holding device for paper packaging for a large rectangular parallelepiped such as a wooden board or a glass board.

[0002]

2. Description of the Related Art As a mechanism for holding side folds in a paper package, for example, as shown in Japanese Patent Application Laid-Open No. 62-94514, for a small rectangular parallelepiped, the space between the holding plates installed according to the width of the object is set. There is a mechanism that presses the paper by passing it through. In this example, the folded folds have higher rigidity of the paper than the resistance of the presser plate, so it is difficult for folds and bulges to occur in the upward direction. Because the rigidity of the
Escape and swelling may occur, causing the package to be degraded.

The inventor of the present invention disclosed in Japanese Unexamined Patent Publication No. Hei 3-56210 that when a large rectangular parallelepiped package is automatically packaged on a transport roller table, the folding of the wrapping paper can be performed with extremely high precision. , A device that can fold ears with a small amount of slack was proposed. In FIG. 3, reference numeral 20 denotes a body winding station, and 21 denotes a paper folding station. The body winding station 20 has 12: rear edge folding device, 13: front edge folding device, 14: front edge folding device, 18: rear edge supporting mechanism, and 30: lower edge folding device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a packing paper holding apparatus for packing a paper excellent in packing form with a simple and single mechanism at various packing material heights.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a swing arm 2 having a folded plate 1 which is movable in a width corresponding to the width of a material 7 to be packed is provided on a base, and a brush 3 having a width larger than a maximum width is attached to a tip thereof. Is provided downstream of the turning plate, has a valve 5 for controlling the pressing pressure of the swing arm, and a flow rate regulator 6 for adjusting the swirling speed. The air actuator and the swing arm 2 which are operated by the supply of compressed air are rotatable. A large rectangular parallelepiped packing paper press device characterized by being connected to a.

According to the present invention, immediately after the material to be packed has passed between the folded plates for folding the paper folds to the side, the escape or bulge generated by pressing the upper surface of the material to be packed with a brush having a width equal to or larger than the maximum width of the material to be packed. By pressing and setting the pressing force arbitrarily, flexible pressing can be performed, and no paper tear or extra wrinkles are generated. Further, by pressing the width end of the material to be packed, the paper can be squared along the side.

Further, the swing arm lifted by the material to be passed does not jump due to the buffering action of the air actuator, and can always press the upper surface of the material to be packed with the brush within the turning range. , Get a good packaging.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The folded plate 1 according to the present invention is fixed to a gantry 10,
Can be adjusted according to the width of the folded plate 1, 1
Is given approximately to the width w of the packing material 7 and preferably has an inclination angle α in the packing material transport direction.

The swing arm 2 according to the present invention is provided near the folded plate and downstream of the folded plate, has a width equal to or greater than the maximum width of the material to be packed, and has an elastic brush 3 attached to the tip. The swing arm 2 is locked by the air actuator 4. The air actuator 4 is a circuit 1 provided with a valve 5.
1 and a circuit 12 having a flow controller 6 to adjust the pressing force and the turning speed of the swing arm 2. Further, since the air actuator and the swing arm 2 are rotatably connected to each other, it is possible to cope with packing materials having various heights.

That is, according to the present invention, the material is wound around the material to be packed,
When folding the side portion of the wrapped packing paper, the side surface can be held down by a folding plate. Furthermore, a swing arm with a brush whose width is greater than the maximum width of the material to be packed from the top surface is provided near the folded plate to suppress the escape and bulge to the top surface of the paper, and the holding force can be controlled, and the swing arm can rotate freely. Since the air actuator is provided so as to be locked, it is possible to cope with various widths and heights with a predetermined pressing force without drive control.

FIG. 2 illustrates the operation of the present invention. At the stage where the wrapping paper is wound around and the side folds are formed, and then the folds are folded into the side of the material to be packed, the upper folds when the material to be packed passes between the folded plates while being conveyed on the conveyor 8. It is folded down by the folded plate. Next, the material to be packed lifts the swing arm, which stands by at the side of the folded plate, to the upper surface. At this time, the air actuator is pressurized so as not to be pressed with a force higher than the required pressing force of the paper, the movement speed is adjusted, and a buffering action is performed. After the material to be packed whose top surface has been pressed down to allow the paper to escape has passed, the swing arm descends by its own weight. At this time, the speed control valve also functions as a buffer.

When the material to be packed is a steel sheet, for example, length:
Although it is 1470 to 3500 mm × width: 500 to 1250 mm, and lamination thickness: 50 to 400 mm, escape and bulging of the paper at the time of folding the paper can be suppressed.

[0013]

According to the paper holding mechanism of the present invention, the paper can be pressed flexibly using a brush and an air actuator even for a large rectangular parallelepiped paper package, and the arm can swing to various packing heights by swinging. It can be handled by a simple and single mechanism.
