Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip removing device for removing a chip remaining on a side edge of an adhesive piece when a paperboard for assembling a cardboard box is formed.

[0002]

2. Description of the Related Art Four side walls are bent at right angles to each other,
Adhesive pieces provided on the edge of the side wall plate at one end are bonded to the edge of the side wall plate at the other end to form a body on a square cylinder, and a canopy connected to the upper and lower edges of each side wall plate There is known a cardboard box formed by closing a lid with a flap and a bottom lid flap. In this type of corrugated cardboard box, a corrugated cardboard box assembling paperboard having a side wall plate, a lid flap, and an adhesive strip is formed by cutting a rectangular corrugated paperboard into a predetermined shape.

Prior to assembling the box, an adhesive is applied to the adhesive pieces while transporting the cardboard for assembling the cardboard box. Conventionally, the application of the adhesive to the adhesive piece is performed by pressing an adhesive application roller against the adhesive surface side of the adhesive piece that is conveyed and moved. But,
The application of the adhesive by the adhesive application roller has a relatively low accuracy, and there is a disadvantage that the application position is shifted or the adhesive is scattered due to the rotation of the application roller. Therefore, in recent years, a spray-type adhesive has been applied with high accuracy of the application position and less scattering of the adhesive. Prior to the application of the adhesive, the position of the adhesive piece is detected by a sensor or the like when the cardboard box assembling paperboard is being conveyed prior to the application of the adhesive. Squirting is done.

[0004] Incidentally, since the adhesive piece is formed in a protruding shape by cutting out the corrugated cardboard around the adhesive piece, the cutting off of the corrugated cardboard around the adhesive piece tends to be insufficient. For this reason, the swarf pieces that have been insufficiently cut may hang down to the side edges of the adhesive pieces in a state where the pieces are partially connected to the adhesive pieces.

When the position of the adhesive piece of the cardboard box assembling board being conveyed as described above is detected by a sensor or the like, if there is a hanging chip piece on the side edge of the adhesive piece, the sensor or the like is detected. Is inaccurate due to the chips, and the application position of the adhesive is displaced.

[0006]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention provides a method for cutting a cardboard box assembling paperboard which can reliably remove chips remaining on the side edges of the adhesive strip when forming the adhesive strip. It is an object to provide a debris removal device.

Since it is sandwiched and entangled, the chip pieces can be easily separated from the adhesive pieces in the middle of transport and removed.

Furthermore, the rotation axes of both rollers, the transport path gradually inclined provided et al is to approach to the transport path toward the downstream side from the upstream side of, cutting debris that moves are sent transportable However, since the rolled portions of the two rollers are obliquely opposed to each other, the chips can be reliably sandwiched between the two rollers.

[0010] Further, the swinging movement of the chip piece moving on both sides of the two rollers in a state of hanging down from the side edge of the adhesive piece along the conveyance path is restricted from both sides in the conveyance direction, and the chip is controlled. A guide plate which is inclined in a direction for guiding the piece in the direction of both rollers is provided.

Since the swarf pieces hang down from the side edges of the adhesive pieces, the swarf pieces may oscillate relatively greatly due to vibrations and the like accompanying conveyance. In the present invention, the provision of the guide plate regulates the position of the outer side of both rollers in contact with the swaying chip pieces,
The inclination of the guide plate guides the chip pieces in the direction of both rollers. Thus, even if the chip pieces are shaken, the chip pieces can be reliably brought into contact with both rollers and sandwiched between the two rollers, and the chip pieces can be reliably removed.

[0012] Further, a chip piece on the adhesive piece moving along the transport path is brought into contact with a chip piece on the adhesive piece at an upper position of the both rollers via the transport path, and the chip piece on the adhesive piece is attached to the adhesive piece. It is characterized in that chip piece contact means for hanging down is provided.

The swarf pieces hanging down from the side edges of the adhesive pieces may be repelled on the adhesive pieces by vibrations during transportation or the like, and may be in a state of being overlapped on the adhesive pieces. According to the present invention, the chip contacting means is provided, and the chip is brought into contact with the chip overlapping the adhesive piece.
Since the swarf is moved along with the adhesive together with the adhesive,
The chip pieces, the movement of which is restricted by the contact with the chip piece contacting means, are removed from the adhesive pieces. This allows
The chip pieces can be made to hang down from the side edges of the adhesive pieces, so that the two rollers can sandwich the chip pieces and separate the chip pieces smoothly.
