Description

  The present invention relates to a ruled line forming device that can bend a resin corrugated board, and more specifically, a resin that can reliably form a ruled line by using a small ruled line roller having a small heat capacity by preheating the resin cardboard board with a laser beam. The present invention relates to a ruled line forming apparatus for corrugated board.

  For example, when manufacturing a container or the like formed by folding a synthetic resin corrugated board (plastic corrugated board) into a box shape, it is possible to fold by forming a ruled line at the folding part of the resin corrugated board that has been cut into the required developed shape I have to. As an apparatus for forming a ruled line on a resin corrugated board, for example, as shown in Patent Document 1, a ruled line thermal processing machine equipped with a heated blade is used, and the heated blade is pressed to a predetermined portion of the resin corrugated board and the back plate A V-groove ruled line is formed by melting in a state where the film remains, and can be bent at the ruled line.

  However, in the ruled line thermal processing machine using the above-described blade, in order to form a ruled line of a certain length at a time, a long blade must be used, which increases in size and weight. The blade has to be heated by the electric heater of the output, and there is a problem that the apparatus itself becomes large.

In addition, since the length of the blade is limited with respect to the ruled line to be formed, when forming a long ruled line, with the edge of the blade aligned with a part of the previously formed ruled line, again However, it has to be pressed and melted while positioning to form ruled lines, and the ruled lines are likely to be discontinuous, and the alignment work is troublesome, and the ruled lines cannot be formed efficiently.

  The above problem is that a heating roller is used instead of a blade, and a ruled line is formed by rolling while pressing the heated ruled line roller against a predetermined portion of the resin corrugated board to leave the back plate and melt it. Can be solved. When such a heated ruled line roller is used, the ruled line roller itself rotates when the ruled line roller is moved in pressure contact with the resin corrugated board.

However, since the amount of rotation is small with respect to the movement of the ruled line roller, there is a problem that the resistance of the ruled line roller is moved and the resin corrugated board around the V-groove is easily broken by the movement resistance. In particular, the resin corrugated board is integrally formed so that a large number of ribs (eyes) extending between a front plate and a back plate in a certain direction to form a gap therebetween are extended at equal intervals. When a ruled line perpendicular to the eyes is formed on the corrugated cardboard, it is possible to avoid breakage even if movement resistance due to the pressing force of the ruled line roller acts on the ribs, but the ruled line in the direction matching the eyes When forming the front plate or the back plate, the front plate or the back plate was easily broken due to the movement resistance due to the pressing force of the ruled line roller.

As a result, when a product is manufactured using a resin corrugated board in which the front or back plate of the ruled line portion is broken, the quality of the folded portion is deteriorated, resulting in a problem that the product becomes defective.

In addition, in order to continuously form a long ruled line with a heated ruled line roller on the resin corrugated board, it is necessary to increase the heat capacity of the ruled line roller, so the forming roller itself is enlarged and a high-output heater is used. Although necessary, the apparatus itself has a problem of increasing in size and weight. In addition, when a small (small diameter) ruled line roller is used, it is necessary to heat the ruled line roller more than necessary, and the ruled line formation portion of the resin corrugated board is melted and whitened by heat, resulting in poor appearance. Have a problem.

The problem to be solved is that when a ruled line is formed with a heated blade, the length of the blade is restricted, so that it tends to be discontinuous when forming a long ruled line, and labor is required for alignment. Therefore, the ruled line cannot be formed efficiently. In addition, when forming a ruled line using a heating roller, a rotation resistance is generated by the rotation of the heating roller being delayed with respect to the movement of the heating roller relative to the resin cardboard board, and the resin cardboard board at the periphery of the ruled line is caused by the rotation resistance. Is easy to break.
In order to increase the heat capacity of the crease roller, it is necessary to use a heater with a large calorific value. However, if a small crease roller is used, the crease roller is overheated and the crease part of the resin corrugated board is It is in the point which causes whitening and the appearance defect.

  According to the present invention, a ruled line roller press-contacted with a resin corrugated board in which a large number of ribs extending in a predetermined direction between a front plate and a back plate are provided with gaps is at least one of the first and second moving members. In a ruled line forming apparatus for forming a ruled line by moving in at least one of a direction corresponding to the rib of the resin corrugated board and a direction orthogonal to the rib, at a rotational speed synchronized with the moving speed of the ruled line roller with respect to the resin cardboard board The main features include a rotating member that rotates the ruled line roller, and heating means that is disposed on the lower side of the ruled line roller in the direction of rotation, and heats and softens the resin corrugated board to a temperature slightly lower than the melting temperature. To do.

  The present invention can efficiently form a continuous ruled line even if it is a long ruled line. In addition, when forming a ruled line using a heating roller, the rotation of the heating roller is prevented from being delayed with respect to the movement of the heating roller relative to the resin cardboard plate, and the resin cardboard plate at the periphery of the ruled line is prevented from breaking. can do. While miniaturizing the apparatus using a small ruled line roller, it is possible to prevent the ruled line portion of the resin corrugated board from whitening and to prevent the appearance of the resin corrugated board from being defective.

Converge to a wider required beam diameter.

Next, the cutting action and ruled line forming action of the resin corrugated board 20 by the ruled line forming apparatus 1 configured as described above will be described.
First, the cutting action of the resin corrugated board 20 will be described. The resin corrugated board 20 is placed on the placing table 21 of the main body frame 3 while being positioned and fixed and held by negative pressure suction from the suction holes 21a. At this time, the first and second traveling bodies are moved to the origin position with respect to the mounting table 21.

Based on the cutting start position data set in advance in the above state, the electric motors 9 and 17 are driven and controlled to move the traveling body 7 and the movable body 17, and the cutting blade 55 a of the cutting and ruled line unit 22 is made of resin cardboard. The plate 20 is positioned above the cutting start position.

In the above state, after the electric motor 29 is driven and controlled to move the elevating plate 27 downward or at a synchronized timing, the operating member 41 is operated to move the second mounting plate 37 downward, and the cutting blade 55a is moved to the resin cardboard. After piercing the board 20, for example, the electric motor 17 is driven and controlled, and the movable body 17 is moved in the front-rear direction perpendicular to the eyes of the resin cardboard board 20 to cut the resin cardboard board 20. (See Figure 3)

In order to cut the resin corrugated board 20 in the left-right direction that coincides with the eyes after the cutting in the front-rear direction perpendicular to the eyes is completed, first, the operating member 41 is moved backward to move the second mounting plate 37 upward. After moving and releasing the piercing of the cutting blade 55a from the resin corrugated board 20, the electric motor 57 is driven and controlled so that the cutting member 55 is rotated in the left-right direction shown in the drawing where the direction of the cutting blade 55a coincides with the eye. .

In the above state, the operating member 41 is actuated again to move the second mounting plate 37 downward and pierce the cutting blade 55a into the resin corrugated board 20, and then drive the electric motor 9 to control the traveling body 7 in the resin corrugated board. The resin corrugated board 20 is cut by moving in the left-right direction that coincides with the eyes of the board 20. (See Figure 4)

By repeating the above operation, the resin corrugated board 20 is cut in the front-rear direction and the left-right direction to form a desired developed shape.

In order to cut the resin corrugated board 20 at a desired angle with respect to the front-rear direction, for example, the electric motor 57 is driven and controlled in accordance with the angle while the second mounting plate 37 is moved upward. Then, after the cutting member 55 is rotated in a direction in which the direction of the cutting blade 55a coincides with the above angle, the operation member 41 is operated to move the second mounting plate 37 downward, and the cutting blade 55a is moved to the resin corrugated board. In a state where the electric motors 9 and 17 are pierced into 20, the drive control of the electric motors 9 and 17 is performed with the rotation amount corresponding to the angle, and the cutting blade 55a is moved in a direction corresponding to the angle to be cut.

Next, in order to form a V-groove ruled line that becomes a crease in the resin corrugated board 20 cut into a desired developed shape by the above operation, the motor is electrically operated based on preset ruled line start position data and the like as described above. The motors 9 and 17 are driven and controlled to move the traveling body 7 and the movable body 17, respectively, and the ruled line roller 53 of the cutting and ruled line unit 22 is positioned above the ruled line start position of the resin corrugated board 20.

In addition, the electric motor 63 is driven and controlled at the timing synchronized with the above operation or after the above operation so that the rotating arm 61 is positioned relative to the fixed arm 59, and the laser light output head 65 is positioned below the rotation direction of the ruled line roller 53. Turn to.

After driving and controlling the electric motor 29 in the above state and moving the elevating plate 27 downward or at a synchronized timing, the operating member 39 is operated to move the first mounting plate 35 downward, and the electric heating member moves the required temperature. Then, the ruled line roller 53 heated to is pressed against the resin corrugated board 20. At this time, the ruled line roller 53 is pressed against the resin corrugated board 20 with the back plate remaining. Further, the laser beam output head 65 is opposed to the upper surface of the resin corrugated board 20 located below the ruled line roller 53 in the rotational traveling direction with a predetermined interval.

In the above state, the laser beam oscillation device is driven to output laser beam from the laser beam output head 65, and the laser beam is applied to the lower upper surface of the resin corrugated board 20 in the direction of rotation of the ruled line roller 53 with a required spot diameter. By converging, the electric motor 17 is driven and controlled while the resin corrugated board 20 is heated to a temperature at which the resin corrugated board 20 is not melted and softened, specifically, a temperature slightly lower than the temperature at which the resin corrugated board 20 melts. The electric motor 45 is moved in the front-rear direction perpendicular to the eyes of the corrugated cardboard plate 20 and driven at a timing synchronized with the start of driving of the electric motor 17 and with the rotation amount corresponding to the movement amount of the movable body 17 in the front-rear direction. The rotating ruled line roller 53 is moved. (See Figure 5)

As a result, the ruled line roller 53 is pressed against the resin corrugated board 20 heated by the laser beam output from the laser beam output head 65 while rotating, and in the front-rear direction with the back board remaining on the resin corrugated board 20. An extending V-groove ruled line is formed. At this time, the ruled line roller 53 is rotated by an amount of rotation corresponding to the amount of movement with respect to the front-rear direction to prevent movement resistance with respect to the resin cardboard plate 20, thereby preventing the resin cardboard plate 20 from breaking at the periphery of the ruled line. .

After the formation of the ruled lines in the front-rear direction with respect to the resin corrugated board 20 is completed, in order to form further ruled lines in the left-right direction that coincide with the eyes, first, the operating member 39 is moved back to move the first mounting plate 35. After moving upward and releasing the pressure contact of the ruled line roller 53 against the resin corrugated board 20, the electric motor 51 is driven to rotate the ruled line roller 53 in the left-right direction shown in the figure, which coincides with the eyes, and the electric motor 63 is operated. By rotating in the reverse direction as described above, the rotation arm 61 is rotated so that the laser beam output head 65 is positioned below the ruled line roller 53 in the rotation direction.

In this state, the actuating member 39 is actuated again to move the first mounting plate 35 downward to press the ruled line roller 53 against the resin corrugated board 20 and to move the laser light output head 65 of the ruled line roller 53 on the resin corrugated board 20. It is made to oppose with the required space | interval with respect to the upper surface of the rotation progress lower side. In this state, the laser light oscillation device is driven to output laser light from the laser light output head 65, and the laser light is converged with a required spot diameter on the lower upper surface of the resin corrugated board 20 in the direction of rotation of the ruled line roller 53. As a result, the electric motor 9 is driven and controlled while the resin corrugated board 20 is heated to a temperature at which the resin corrugated board 20 is not melted and softened, specifically, a temperature slightly lower than the temperature at which the resin corrugated board 20 is melted. In the state where the back plate is left behind the resin corrugated board 20 while the electric motor 45 is driven and controlled by the amount of rotation corresponding to the amount of movement of the traveling body 7 in the left and right direction while being moved in the left and right direction matching the eyes of the plate 20 A V-groove ruled line extending in the left-right direction is formed. (See Figure 6)

At this time, the ruled line roller 53 avoids the occurrence of movement resistance with respect to the resin corrugated board 20 by rotating by the rotation amount corresponding to the movement amount in the left-right direction in the same manner as described above. Prevent breakage.

By repeating the above operation, desired ruled lines extending in the front-rear direction and the left-right direction are formed on the resin corrugated board 20.

For example, in order to form a ruled line that is inclined at a desired angle with respect to the front-rear direction on the resin corrugated board 20, the electric motor 51 is driven in accordance with the angle while the first mounting plate 37 is moved upward. The direction of the ruled line roller 53 is controlled to rotate in a direction that coincides with the above angle, and the electric motor 63 is driven to control the rotation arm 61, so that the laser beam output head 65 is positioned below the rotation direction of the ruled line roller 53. Rotate to

In this state, the actuating member 39 is actuated again to move the first mounting plate 35 downward to press the ruled line roller 53 against the resin corrugated board 20 and to move the laser light output head 65 to the ruled line roller 53 on the resin corrugated board 20. The electric motors 9 and 17 are respectively driven and controlled by the rotation amount corresponding to the angle in a state of being opposed to the lower upper surface of the rotation traveling direction of the laser beam, and the laser beam output head 65 and the ruled line roller 53 are integrated in a direction matching the angle. A ruled line that coincides with the above angle is formed by the ruled line roller 53 while being moved and heated on the upper surface of the resin corrugated board 20 by laser light.

In the above description, the heating means is constituted by the laser light output head 65 connected to the laser light oscillation device. However, the heating means of the present invention is, for example, by a heated air injection member that injects air heated to about 500 ° C. The resin corrugated board 20 corresponding to the lower side of the direction of rotation of the ruled line roller 53 may be softened by preheating with heated air.

In the above description, the first to third rotating members are constituted by the electric motors 45, 57, 63. However, the rotation angle of the ruled line roller 53, the cutting member 55, and the laser light output head 65 (heated air injection member) is constant. In this case, a linear motion member such as an air cylinder may be connected to these via a link and rotated.

In the above description, when the ruled line roller 53 is changed to a direction coinciding with the direction of the eyes on the resin corrugated board 20 or a direction perpendicular to the eyes, the electric motor 63 is driven to drive the laser light output head 65 (the heated air injection member). ) Is positioned on the lower side of the rotation direction of the ruled line roller 53, but the rotation direction of the first mounting plate 35 is at a required angle, for example, a direction coincident with the eyes of the resin corrugated board 20, and perpendicular to the eyes. The two ruled line rollers 53 are provided so as to move in the vertical direction at an angle of 90 degrees facing the direction of rotation, and two laser beam output heads are provided at positions corresponding to the lower side of the rotation direction of each ruled line roller 53. The structure which arrange | positioned 65 (heating air injection member) may be sufficient. In this modified example, the electric motor 45 as the first rotating member that changes the rotation traveling direction of the ruled line roller 53 can be eliminated.

Further, the above description is based on the ruled line roller 53 heated by the laser beam output from the laser beam output head 65 in a state in which the resin corrugated board 20 corresponding to the lower side of the ruled line roller 53 in the rotational traveling direction is preheated and softened. Further, the V-shaped ruled lines are formed by melting, but as shown in FIG. 7, the resin corrugated board 20 preheated by laser light (heated air) and softened without melting is melted or melted. A V-shaped ruled line in which gaps are sealed may be formed by press-contacting a ruled line roller heated at a temperature lower than the temperature to stretch and deform the resin plate on the front side.
