Description

The present invention relates to a three-dimensional printer capable of laminating predetermined materials to form a laminate having a desired shape.

A three-dimensional printer usually has a nozzle capable of discharging molten resin and a table capable of sequentially receiving the molten resin discharged from the nozzle and stacking them upward, and the nozzle and the table are orthogonal to each other in the X-axis direction. , By moving relative to the Y-axis direction and the Z-axis direction, a laminate having a desired shape can be formed on the table. Further, the table is swung around the B axis (centered on an axis substantially parallel to the mounting surface of the table) to incline the laminate on the table at an arbitrary angle, and the table is rotated to be on the table. The undercut portion is formed by rotating the laminate around the C axis (centering on an axis substantially orthogonal to the mounting surface of the table) to rotate the laminate on the table and discharging the molten resin from the nozzle. It has been proposed that the laminate having the above can be molded with high accuracy.

However, in the process of ejecting the molten resin material from the nozzle to form the laminate, the applicant suspends the molding once, and then ejects the molten resin material from the nozzle again to perform the subsequent lamination, due to the interruption. We have proposed a three-dimensional printer provided with a heating means that heats and melts a laminated portion that has been cooled and solidified to enable further lamination (see, for example, Patent Document 1). In such a conventional three-dimensional printer, a blow heater is arranged in the vicinity of the nozzle, and after the molding is interrupted and the laminate is cooled and solidified, the molten resin material is discharged again from the nozzle to restart the lamination. It was configured so that it could be melted by injecting hot air from the blow heater to the part to be made to melt.

It may be the fixing material D3.

The moving means is such that the discharging means 2 and the table 3 can be moved relative to the X-axis direction. In the present embodiment, the moving means 4 for the X-axis, the moving means 5 for the Y-axis, and the moving means for the Z-axis are moved. It is composed of means 6. Of these, the X-axis moving means 4 and the Y-axis moving means 5 are attached to the frame F2 located at the upper part of the housing K, and move the discharging means 2 and the cutting tool 11 described later in the X and Y directions. The Z-axis moving means 6 is attached to the frame F1 located on the side of the housing K, and the holding means 12 can be moved in the Z direction.

Specifically, as shown in FIGS. 2 and 4, the X-axis moving means 4 has a ball screw N1 that rotates by driving an actuator such as a motor m1 and a slide that slides along the rail L1 by the rotation of the ball screw N1. It is configured to have a member T1. Further, as shown in the figure, the Y-axis moving means 5 has a ball screw N2 that is rotated by driving an actuator such as a motor m2, and a slide member T2 that slides along the rail L2 by the rotation of the ball screw N2. It is composed of.

The rail L1 extends in the X-axis direction in the frame F2 of the housing K, and the slide member T1 can be moved in the X-axis direction along the rail L1 by the rotation of the ball screw N1. The slide member T1 extends in the Y-axis direction, and the slide member T2 can be moved in the Y-axis direction along the rail L2 by the rotation of the ball screw N2. Further, a mounting member B1 to which the discharging means 2 and the cutting tool 11 are attached is fixed to the slide member T2, and the ball screw N1 is rotationally driven to move the discharging means 2 and the cutting tool 11 in the X-axis direction.

That is, according to the instruction by the control means 9, the moving means (X-axis moving means 4, Y-axis moving means 5 and Z-axis moving means 6), the B-axis swinging means 7, and the C-axis rotating means 8 are arbitrarily selectively selected. By moving the discharge means 2 and the table 3 relative to each other, a laminate having a desired shape can be formed on the receiving member 14.

In particular, by arbitrarily operating the B-axis swinging means 7 and the C-axis rotating means 8, the resin material can be laminated while the laminate is tilted and rotated by a predetermined angle, so that the resin material can be laminated upward. Even when molding a laminate having a wide portion (undercut portion), it is possible to prevent the molten resin from hanging downward due to gravity when molding the undercut portion, which is unnecessary as a product. Molding of the support structure (support structure) can be eliminated.

It is possible to move the magazine 15 to the position and automatically attach the desired cutting tool 11 to the spindle S.

In the process of ejecting the molten resin material from the nozzle portion 2a of the ejection means 2 to form the laminate, the heating means 10 temporarily interrupts the molding due to, for example, cutting by the cutting tool 11, and then again the molten resin material from the nozzle. Is discharged to perform the subsequent lamination, the laminate cooled and solidified by the interruption is heated and melted to enable further lamination. Here, as shown in FIGS. 13 to 17, the heating means 10 according to the present embodiment has a box-shaped accommodating means 10a capable of accommodating the laminate on the receiving member 14, and the laminate housed in the accommodating means 10a. It is configured to have a heater 10b capable of heating an object.

Specifically, the accommodating means 10a is composed of a box-shaped member having an internal accommodating space facing sideways at the opening A, and can be accommodated in the internal accommodating space by inserting a laminate through the opening A. In addition, a heater 10b for heating the internal accommodation space by generating heat when energized is attached. As a result, the laminate on the receiving member 14 can be accommodated inside the accommodating means 10a, and the accommodated laminate can be heated by the heat generated by the heater 10b.

Further, as shown in FIGS. 13 to 17, the heating means 10 according to the present embodiment is movable by the drive mechanism P. The drive mechanism P is attached to a pinion P1 that can be moved by an actuator such as a cylinder S1, a rack P2 that is attached to a moving member H1 connected to the accommodating means 10a and meshed with the upper part of the pinion P1, and a fixing member H2.

Further, as shown in FIGS. 5, 13, 16, 17 and the like, the heating means 10 according to the present embodiment is a cover member installed in the housing K (in the present embodiment, installed at a position adjacent to the magazine 15). The accommodating means 10a is arranged in the cover member 13 through the opening 13a formed at a predetermined position of the cover member 13 by driving the drive mechanism P, and the accommodating means 10a is in a standby position inside the cover member 13 and the cover member. It is capable of moving between 13 external containment positions.

However, in the present embodiment, as shown in FIG. 13, the table 3 (and the receiving member 14) is arranged in the direction in which the accommodating means 10a of the heating means 10 opens, and as shown in FIG. 16, B The table 3 is swung by the shaft swinging means 7 by about 90 degrees so that the laminate on the receiving member 14 faces the opening A of the accommodating means 10, and the accommodating means 10a is driven by driving the drive mechanism P. By moving from the standby position to the accommodating position, as shown in FIG. 17, the laminate can be inserted through the opening A of the accommodating means 10a and accommodated.

In this way, in the state where the laminate is accommodated in the accommodating means 10a, by rotating the table 3 with the C-axis rotating means 8, the laminate on the receiving member 14 can be heated by the heater 10b while rotating. Has been done. In particular, in the present embodiment, by covering the opening A of the accommodating means 10a with the table 3 (which may be the receiving member 14), the laminate can be heated by the heater 10b while keeping the inside of the accommodating means 10a substantially sealed. ing. Strictly speaking, a slight clearance is formed between the table 3 and the peripheral edge of the opening A of the accommodating means 10a, but it is sufficient if the accommodating means 10a can be substantially sealed.

Further, the heating means 10 according to the present embodiment includes a fan 10c capable of introducing outside air into the accommodating means 10a and allowing the air heated by the heater 10b to circulate in the accommodating means 10a. The fan 10c is attached to the wall portion of the accommodating means 10a to which the heater 10b is attached, and is operated by energization to introduce outside air into the accommodating means 10a, thereby causing the inside of the accommodating means 10a heated by the heater 10b. Air can be circulated around the laminate.

When the heating by the heating means 10 is completed, the drive mechanism P is driven to move the accommodating means 10a from the heating position (see FIG. 17) to the standby position (see FIG. 16), and then the B-axis swinging means 7 Is operated to swing the table 3 back to the original normal state (see FIG. 13), and the molten resin discharged from the discharge means 2 is further laminated on the heated laminate. A shutter 13b (see FIG. 5) that closes the opening 13a is attached to the cover member 13, and the shutter 13 is in a closed state except when the laminate is heated. As a result, chips and the like generated during cutting are prevented from entering the inside through the opening A of the accommodating means 10a.

According to the present embodiment, the heating means 10 has a box-shaped accommodating means 10a capable of accommodating the laminate on the receiving member 14, and a heater 10b capable of heating the laminate accommodated by the accommodating means 10a. Therefore, for example, after the ejection and laminating of a predetermined material are interrupted by cutting with the cutting tool 11, the laminated material can be sufficiently and evenly heated so that further laminating can be performed with high accuracy.

Further, by covering the opening A of the accommodating means 10a with the table 3 or the receiving member 14, the laminate can be heated by the heater 10b while keeping the inside of the accommodating means 10a substantially sealed, so that the heating efficiency is further improved. It is possible to heat the laminate sufficiently and evenly in a short time. When the laminate is heated by the heating means 10, the opening A of the accommodating means 10a may be covered with another means, or the opening A may be heated without being covered.

Further, the table 3 is arranged in the direction in which the accommodating means 10a of the heating means 10 opens, and the table 3 is swung by the B-axis swinging means 7 to open the laminate on the receiving member 14 in the accommodating means 10a. Since the laminate was placed facing A and the laminate was inserted through the opening A of the accommodating means 10a to be accommodating, the B-axis swinging means 7 was used to enter the opening A of the accommodating means 10a on the receiving member 14. Can be confronted with each other, and the laminate can be smoothly accommodated in the accommodating means 10a. In the present embodiment, the accommodating means 10a is moved to accommodate the laminate, but the table 3 or both the table 3 and the accommodating means 10a are moved to accommodate the laminate in the accommodating means 10a. You may do it.

Furthermore, in a state where the laminate is accommodated in the accommodating means 10a, by rotating the table 3 with the C-axis rotating means 8, the laminate on the receiving member 14 can be heated by the heater 10b while rotating. Therefore, the C-axis rotating means 8 can be used to rotate the laminate in the accommodating means 10a, and the entire laminate can be heated more evenly. In addition, the heating means 10 according to the present embodiment includes a fan 10c capable of introducing outside air into the accommodating means 10a and allowing the air heated by the heater 10b to circulate in the accommodating means 10a. Can be heated even more evenly.

Further, the holding means 12 for holding the table 3 while enabling swinging around the B-axis α and rotation around the C-axis β is provided, and the holding is performed by the weight of the laminate on the receiving member 14. Since the bending direction γ of the means 12 and the swinging direction of the table 3 by the B-axis swinging means 7 are matched, the bending amount of the holding means 12 due to the weight of the laminate is swung by the B-axis swinging means 7. Can be corrected with, and the laminate can be formed with higher accuracy.
