Description

Technical Field

[0001] The present invention relates to a film forming apparatus including a discharge unit that discharges a coating agent, and a method for manufacturing a film part.

Background Art

[0002] Conventionally, a printing device for a frame material has been proposed that prints a position identification mark indicating the position where a mating part abuts and a mating part identification mark for identifying the mating part on the surface position where parts made of a frame material, which is an aluminum extruded shape, abut against each other (see, for example, Patent Document 1). For the ink used for printing in this printing device for a frame material, thermosetting ink or UV ink that can be wiped off by applying alcohol or a solvent after assembling the structure is used.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Generally, when an operator assembles a structure (such as a prototype or a product) composed of a plurality of parts, the operator performs the work while referring to a procedure manual on which drawings, instructions, etc. are described. At that time, when there are a plurality of similar parts or when the fixed position, mounting angle, etc. are strictly specified, the operator needs to confirm the procedure manual and the parts with a tool. Specifically, the operator repeatedly compares the drawing and the parts, or uses a ruler, a jig, etc. to carefully assemble, so the work efficiency deteriorates. Also, if an error or assembly defect is detected in the next process or inspection process, the operator has to go back to the previous process and reassemble.

[0005] As with the frame material printing equipment mentioned above, directly printing onto aluminum material with thermosetting or UV ink requires solvents such as alcohol to remove the ink. In this case, safety concerns for workers (allergies, skin irritation, organic solvent poisoning, etc.) and handling precautions are necessary, posing challenges to the work environment. Furthermore, depending on the material of the parts (e.g., acrylic), there is a concern that alcohol may cause chemical cracks and damage.

[0006] The object of the present invention is to provide a coating forming apparatus and a method for manufacturing coated parts that can easily remove markings for improving assembly work efficiency and avoid limitations on the material of the parts. [Means for solving the problem]

[0007] In one embodiment, the coating forming apparatus includes a dispensing unit that dispenses a peelable, water-soluble coating agent, and a control unit that acquires information on a coating area that is part of the target surface of a part used in the assembly of a structure and includes a portion to be marked, and controls the dispensing unit to dispense the coating agent onto the coating area of ​​the part. [Effects of the Invention]

[0008] According to the above embodiment, markings for improving assembly work efficiency can be easily removed, and limitations on the material of the parts can be avoided. [Brief explanation of the drawing]

[Figure 5B] This is an explanatory diagram (part 2) illustrating the assembly of parts and the removal of the coating agent in one embodiment. [Figure 5C] This is an explanatory diagram (part 3) illustrating the assembly of parts and the removal of the coating agent in one embodiment. [Figure 6] This is a perspective view showing a coating forming apparatus according to a modified embodiment. [Modes for carrying out the invention]

[0010] Hereinafter, a method for manufacturing a coating-forming apparatus and a coated part according to one embodiment of the present invention will be described with reference to the drawings.

[0011] Figure 1 is a perspective view showing the coating forming apparatus 1.

[0012] Figure 2 is a block diagram showing the main control configuration of the coating forming apparatus 1.

[0013] Note that the front-to-back, up-and-down, and left-to-right directions shown in Figure 1 and Figures 5A to 5C and 6 described later are examples where the main scanning direction D1 is the left-to-right direction and the sub-scanning direction D2 is the front-to-back direction. For example, the front-to-back and left-to-right directions are horizontal, and the up-and-down direction is vertical.

[0014] As shown in Figure 1, the coating forming apparatus 1 comprises a dispensing unit 10, a marking unit 20, a gantry unit 30, and a table 40. Also, as shown in Figure 2, the coating forming apparatus 1 comprises a control unit 51, a storage unit 52, a display unit 53, an input unit 54, and an interface unit 55.

[0015] The discharging unit 10 is, for example, a dispenser that discharges a peelable water-soluble coating agent C (illustrated with a dot pattern in FIG. 5A etc.). The area where the discharging unit 10 discharges the coating agent C is the coating area A1 shown in FIG. 4 described later. The coating agent C is mainly composed of, for example, a water-soluble resin. As the coating agent C, a known paint or the like for use as a whiteboard with a peelable arbitrary wall surface can be used.

[0016] The discharging unit 10 moves in the main scanning direction D1 along the front surface of the horizontal part 31 of the portal unit 30. Therefore, the discharging unit 10 can be called a carriage having an actuator (main scanning driving unit) such as a motor for moving the discharging unit 10 in the main scanning direction D1. Further, since the portal unit 30 described later moves in the sub-scanning direction D2, the discharging unit 10 can also move in the sub-scanning direction D2. Therefore, the discharging unit 10 can discharge the coating agent C at an arbitrary position on the target surface P1a which is the upper surface of the first part P1 placed on the table 40. Here, the first part P1 is used for the assembly work of a structure including attachment (such as adhesion, fastening, fitting, etc.) to the second part P2 shown in FIG. 5A. The first part P1 and the second part P2 are made of, for example, an acrylic material, and the first part P1 has a flat plate shape. The second part P2 includes a large-diameter cylindrical portion and a small-diameter cylindrical portion that protrudes radially from the outer periphery of the large-diameter cylindrical portion.

[0017] The discharging unit 10 may have a drying part such as a heater or a hot air generator to dry the discharged coating agent C. Alternatively, the drying part may be arranged in the coating forming apparatus 1 independently of the discharging unit 10.

[0018] The marking unit 20 is, for example, an inkjet head, and forms markings M1, M2 (see FIGS. 5A, etc.) on the coating agent C. The markings M1, M2 may be formed by a non-aqueous ink (such as an oil-based ink or a UV ink). The marking unit 20 is arranged to be movable in the main scanning direction D1 and the sub-scanning direction D2, similar to the ejection unit 10, for example, by being fixed to the ejection unit 10. Therefore, the marking unit 20 can form a marking M1 (M2) at any position on the target surface P1a (P2a), which is the upper surface of the first part P1 (or the second part P2) placed on the table 40.

[0019] As shown in FIG. 4, the marking M1 of the first part P1 may include an information display portion M1a, an angle display portion M1b, and a position display portion M1c. The information display portion M1a may be a portion for displaying work information (assembly information) such as "fix the part (2) to a", part names, comments, etc. The angle display portion M1b is a portion for displaying, as an example of a mark indicating the mounting angle (orientation) with respect to another part such as the second part P2, a "straight line", and the character "a", which is an example of supplementary information for the mounting angle. The position display portion M1c is a display portion representing the mounting area A2 of another part such as the second part P2, and may be, for example, a "broken line" surrounding the mounting area A2.

[0020] As shown in FIG. 1, the portal unit 30 has a horizontal portion 31, a right leg portion 32, and a left leg portion 33, and exhibits a portal shape. Since the ejection unit 10 moves along the front surface as described above, a rail extending in the main scanning direction D1 and guiding the ejection unit 10 may be provided on the front surface of the horizontal portion 31. The right leg portion 32 supports the lower right portion of the horizontal portion 31, and the left leg portion 33 supports the lower left portion of the horizontal portion 31.

[0021] The gantry unit 30 is positioned to straddle the table 40, and its right leg 32 and left leg 33 move along the left and right sides of the ground in the sub-scanning direction D2. Therefore, the gantry unit 30 has an actuator (sub-scanning drive unit) such as a motor to move the gantry unit 30 in the sub-scanning direction D2. In addition, it is preferable that a pair of rails extending in the sub-scanning direction D2 and guiding the right leg 32 and left leg 33 be provided on the floor or the like at the bottom of the right leg 32 and left leg 33.

[0022] Table 40 has a table on which parts such as the first part P1 are placed. The upper surface of Table 40 is provided with a reference section 41 used for positioning the first part P1. This reference section 41 is, for example, an L-shaped positioning projection, against which the first part P1 is pressed. The reference section 41 can be used in common for positioning the first part P1 when the coating agent C is dispensed by the dispensing section 10 and for positioning the first part P1 when the marking M1 is formed by the marking section 20. Note that the reference section 41 is not limited to a positioning projection, but may also be a mark placed on the upper surface of Table 40 or a mark such as laser light emitted by the laser irradiation section. Even if the reference section 41 is a mark, if the dispensing section 10 or the marking section 20 recognizes the reference section 41 by imaging, the reference section 41 can be used for positioning the first part P1. In addition, a guide section used for holding the position of the first part P1 may be provided on Table 40 separately from the reference section 41. Additionally, attachments for bundling and installing multiple pieces of lumber as parts, or attachments for dispensing the coating agent C while rotating a cylindrical part, may be used.

[0023] The control unit 51 shown in Figure 2 has a processor (e.g., CPU: Central Processing Unit) that functions as an arithmetic processing unit that controls the operation of the coating forming apparatus 1, and controls the operation of each part of the coating forming apparatus 1. As will be described in detail later, the control unit 51 acquires information on the coating area A1 and controls the dispensing unit 10 to dispense the coating agent C onto the coating area A1 of the first part P1 (second part P2). The information on the coating area A1 can be acquired from a user terminal via the interface unit 55, which will be described later, or from the storage unit 52 or input unit 54, which will be described later.

[0024] The memory unit 52 may include, for example, a ROM (Read Only Memory), which is a read-only semiconductor memory in which a predetermined control program is pre-recorded, or a RAM (Random Access Memory), which is a semiconductor memory that can be written to and read at any time and used as a working memory area as needed when the processor executes various control programs, or a hard disk drive.

[0025] The display unit 53 includes a display, lamps, etc., that show various types of information.

[0026] The input unit 54 is an operation key, touch panel, etc., that accepts input information from the user (operator). A single operation panel may function as both the display unit 53 and the input unit 54.

[0027] The interface unit 55 exchanges various types of information with external devices such as a user terminal that transmits information about the coating area A1 and markings M1 and M2 to the coating forming apparatus 1.

[0028] Next, the manufacturing method of the coated part will be explained using the first part P1 as an example, referring to the flowchart in Figure 3. Here, the coated part is the part (first part P1) to which the coating agent C has been applied.

[0029] As shown in Figure 3, the control unit 51 acquires information about the coating area A1 from the user terminal or the input unit 54 (step S1). This information about the coating area A1 may include information about the position of the coating area A1 on the target surface P1a of the first part P1, and may also include information such as the discharge amount (thickness of the coating agent C). The information about the coating area A1 and the marking M1, which will be described later, may be created, for example, when the designer creates the design data using CAD. The positions of the coating agent C and the marking M1 may be set according to the reference unit 41. The control unit 51 acquires information about the coating area A1 from the designer terminal, user terminal or input unit 54 via the interface unit 55, but it may also acquire previously acquired information about the coating area A1 from the storage unit 52. Alternatively, the control unit 51 may determine the position (information) of the coating area A1 based on the acquired marking M1. In this case, it can be said that the control unit 51 acquires the coating area A1 by determination.

[0030] As shown in Figure 4, the coated area A1 is only a portion of the target surface P1a of the first part P1. Furthermore, the coated area A1 is preferably located in the area surrounding the mounting area A2 on the target surface P1a of the first part P1, where other parts (for example, the second part P2 shown in Figure 5A) are attached, excluding the mounting area A2. For example, the coated area A1 may be the area excluding a slightly larger area than the mounting area A2 (for example, a circular area). Note that since the marking M1 is formed on the coating agent C as shown in Figure 4, the coated area A1 can be said to be the area that includes the part to be marked.

[0031] Returning to Figure 3, the control unit 51 acquires information about the marking M1 from the user terminal or input unit 54, similar to the information about the coated area A1 (step S2). This information about the marking M1 is, for example, printed image data and may include an information display portion M1a, an angle display portion M1b, and a position display portion M1c, as described above. Furthermore, the marking portion 20 does not only form the marking M1, but may also decorate the areas without the coating agent C with an arbitrary design (which will not be removed after completion) by printing. Note that the information about the coated area A1 and the information about the marking M1 may be acquired simultaneously, or the marking M1 may be acquired first.

[0032] Based on the acquired information about the coated area A1, the control unit 51 controls the dispensing unit 10 to dispense the coating agent C onto the coated area A1 of the first part P1 (step S3).

[0033] Subsequently, if the discharge unit 10 has a drying unit such as a heater or a hot air generator, the control unit 51 dries (forced-drys) the coating agent C using the discharge unit 10 (step S4). Alternatively, the control unit 51 automatically removes the first part P1 from the coating forming device 1 to allow the coating agent C to air dry or be forced-dried using an external drying device, or notifies the operator, for example, by a display on the display unit 53, to remove the first part P1 from the coating forming device 1.

[0034] After the coating agent C has dried, the control unit 51 controls the marking unit 20 to form the marking M1 on the coating agent C (step S5), and the process shown in Figure 3 is completed. As a result, the first part P1 (coated part) with the coating agent C and marking M1 formed on it is completed, as shown in Figure 5A.

[0035] As shown in Figure 5A, the coating agent C and marking M2 are formed on the second part P2 in the same manner as the flowchart shown in Figure 3. As described above, the second part P2 includes a large-diameter cylindrical portion and a small-diameter cylindrical portion that protrudes radially from the outer circumference of the large-diameter cylindrical portion. The coating agent C of the second part P2 is formed in a coating region (the same region as the coating agent C shown in Figure 5A) that includes the marking M2 (the portion to be marked) and is part of the target surface P2a, which is the outer surface of the large-diameter cylindrical portion. The marking M2 of the second part P2 includes an information display portion M2a and an angle display portion M2b. The information display portion M2a is the part that displays the letters "(2)" which represent the part name of the second part P2. The angle display portion M2b is the part that displays "straight line", which is an example of a marker that represents the mounting angle (direction) with other parts (first part P1), and the letter "a", which is an example of supplementary information for the mounting angle. Although the explanation is omitted, the small-diameter cylindrical portion of the second part P2 is also pre-fixed to the large-diameter cylindrical portion in the same manner as the second part P2 is attached to the first part P1 (illustrations of the coating agent C and marking M2 are omitted).

[0036] Next, referring to Figures 5A to 5C, we will explain the assembly of the coated parts (first part P1 and second part P2) and the removal of the coating agent C.

[0037] As shown in Figure 5A, the first part P1 and the second part P2 have the markings M1 and M2 described above. Therefore, the worker looks at the text "Align part (2) with a and fix it" in the information display part M1a of the marking M1 of the first part P1, and first prepares the second part P2 which corresponds to "part (2)".

[0038] Then, as shown in Figure 5B, the worker places the second part P2 within the position indicator M1c of the first part P1 and adjusts the angle of the second part P2 by aligning the "straight lines" marked with the letter a on the angle indicators M1b and M2b of the first part P1 and the second part P2. This allows for positional adjustment of the first part P1 and the second part P2 without misalignment or misalignment of angles. The worker then attaches the second part P2 to the first part P1 by adhesive or other means. The worker assembles the parts while referring to the diagram in the procedure manual and the markings M1 and M2 on the first part P1 and the second part P2, but it is also possible to fix the first part P1 and the second part P2 by referring only to the markings M1 and M2.

[0039] Once the installation of the first part P1 and the second part P2 is complete, the worker can peel off the coating agent C by hand if it can be removed while maintaining its sheet-like form. Alternatively, the worker can remove the coating agent C by wiping it with a nonwoven cloth soaked in water. As a result, the markings M1 and M2 are removed together with the coating agent C, as shown in Figure 5C. Note that the worker may lift the coating agent C by hand in large areas and wipe it off in small areas such as gaps.

[0040] In the embodiment described above, the coating forming apparatus 1 comprises a discharge unit 10 and a control unit 51. The discharge unit 10 discharges a peelable, water-soluble coating agent C. The control unit 51 acquires information on a coating area A1 that includes a portion of the target surfaces P1a and P2a of a first part P1 and a second part P2 (an example of a part) used in the assembly of a structure, and which includes a portion to be marked (step S1), and controls the discharge unit 10 to discharge the coating agent C onto the coating area A1 of the first part P1 and the second part P2 (step S3).

[0041] Furthermore, from the perspective of a method for manufacturing coated parts, the manufacturing method includes acquiring information on a coated area A1 that includes a portion of the target surfaces P1a and P2a of a first part P1 and a second part P2 (an example of a part) used in the assembly of a structure, and which includes a portion to be marked (step S1), and discharging a peelable water-soluble coating agent C onto the coated area A1 of the first part P1 and the second part P2 (step S3).

[0042] This allows workers to perform assembly work while viewing the markings M1 and M2 formed on the target surfaces P1a and P2a of the first part P1 and second part P2, respectively, thus improving the efficiency of the assembly process. Furthermore, since a water-soluble coating agent C is dispensed onto the first part P1 and second part P2, even if markings M1 and M2 are formed on the coating agent C, they can be easily removed together with the coating agent C by peeling off the coating agent C. Therefore, solvents such as alcohol are not required to remove the markings M1 and M2, thus avoiding the need for worker safety precautions (allergies, skin irritation, organic solvent poisoning, etc.) and handling precautions. In addition, acrylic materials that are prone to chemical cracking due to alcohol can be used as the first part P1 and / or second part P2. In the case where markings M1 and M2 are directly formed on the target surfaces P1a and P2a using easily removable water-based ink, the markings M1 and M2 do not adhere properly, and the ink of the markings M1 and M2 is repelled or rubbed off, making it impossible to streamline the assembly process. Therefore, according to this embodiment, the markings M1 and M2 used to streamline the assembly process can be easily removed, and the limitations on the material of the parts (first part P1 and / or second part P2) can be avoided.

[0043] Furthermore, by dispensing the coating agent C onto a portion of the target surfaces P1a and P2a of the first part P1 and second part P2, including the area to be marked, the amount of coating agent C used can be reduced compared to applying the coating agent C to the entire surface P1a and P2a using, for example, a brush. Also, the coating agent C can be applied even if the target surfaces P1a and P2a are curved or uneven (rough) surfaces. In addition, by dispensing the coating agent C with precision at any desired position, the coating agent C can be dispensed close to the mounting area A2 of the first part P1 where the second part P2 is attached, forming a position indicator area M1c such as a "dashed line" surrounding the mounting area A2 on the coating agent C, or preventing the coating agent C from entering the mounting area A2. Therefore, assembly work efficiency is further improved.

[0044] In this embodiment, markings M1 and M2 are formed on the coating agent C using a non-aqueous ink on the area to be marked. The coating agent C is mainly composed of a water-soluble resin and is peeled off integrally with the markings M1 and M2 while maintaining its sheet-like state or by wiping.

[0045] In this way, markings M1 and M2 are formed with non-aqueous ink, allowing them to be formed on a water-soluble coating agent C. Furthermore, by peeling off the coating agent C together with the markings M1 and M2, either while maintaining its sheet-like state or by wiping, the markings M1 and M2 can be removed even more easily. However, if markings M1 and M2 are formed with water-based ink on a coating agent C whose main component is a water-soluble resin, the coating agent C will dissolve.

[0046] Furthermore, in this embodiment, the coated area A1 is located around the mounting area A2 on the target surface P1a of the first part P1, where the second part P2 (an example of another part) is attached.

[0047] Therefore, it is possible to avoid the coating agent C entering the mounting area A2 and hindering the attachment of the first part P1 and the second part P2. Furthermore, compared to a configuration in which the coating agent C remains in the mounting area A2 after assembly, it is also possible to avoid the coating agent C showing through and impairing the appearance, or the coating agent C affecting the optical performance of the structure, when at least one of the first part P1 and the second part P2 is transparent.

[0048] In this embodiment, the coating forming apparatus 1 further comprises a marking section 20 and a reference section 41. The marking section 20 forms markings M1 and M2 on the portion of the coating agent C intended for marking. The reference section 41 is used in common for aligning the first part P1 (or second part P2) when the coating agent C is dispensed from the dispensing section 10 and for aligning the first part P1 (or second part P2) when the markings M1 and M2 are formed in the marking section 20. From the viewpoint of the method for manufacturing the coated part, the manufacturing method further includes forming markings M1 and M2 on the portion of the coating agent C intended for marking, and uses a reference section 41 common to both aligning the first part P1 (or second part P2) when the coating agent C is dispensed and for aligning the first part P1 (or second part P2) when the markings M1 and M2 are formed.

[0049] As a result, from the perspective of the coating forming apparatus 1, the coating agent C and markings M1 and M2 can be formed in a single coating forming apparatus 1. Furthermore, even if the first part P1 and the second part P2 are removed from the coating forming apparatus 1 to allow the coating agent C to air dry outside the coating forming apparatus 1 or to be forcibly dried in a drying apparatus outside the coating forming apparatus 1, the positional displacement of the first part P1 and the second part P2 between the formation of the coating agent C and the formation of the markings M1 and M2 can be prevented by using the reference part 41. Also, from the perspective of the method of manufacturing the coated part, a coated part with the coating agent C and markings M1 and M2 formed on it can be manufactured.

[0050] In the above description, the coating forming apparatus 1 shown in Figure 1 is assumed to include both a dispensing unit 10 and a marking unit 20. However, the coating forming apparatus 1 only needs to include at least a dispensing unit 10 and a control unit 51. Furthermore, from the viewpoint of the manufacturing method of the coated part, it is sufficient if only the coating agent C is formed among the coating agent C and markings M1 and M2. Therefore, a coating forming apparatus 2 without a marking unit 20 may be used, as shown in the modified example in Figure 6. In this case, the markings M1 and M2 may be formed by a marking forming apparatus arranged separately from the coating forming apparatus 1, or by handwriting by an operator. Note that the coating forming apparatus 2 shown in Figure 6 is the same as the coating forming apparatus 1 shown in Figure 1, but without the marking unit 20.

[0051] Furthermore, in the above description, the coating forming apparatus 1 is a flatbed type equipped with a gantry unit 30, and the dispensing unit 10 can be moved in the main scanning direction D1 and the sub-scanning direction D2. However, the dispensing unit 10 and the first part P1 only need to move relative to each other in the main scanning direction D1 and the sub-scanning direction D2. For example, the table 40 on which the first part P1 is placed may move in the main scanning direction D1 and the sub-scanning direction D2, or a conveyor (belt conveyor or roller conveyor) that transports the first part P1 may be used instead of the table 40. Alternatively, the dispensing unit 10 may be a line head that dispenses the coating agent C over the entire main scanning direction D1, and the dispensing unit 10 and the first part P1 may move relative to each other only in the sub-scanning direction D2.

[0052] Furthermore, while the above description described an example in which the markings M1 and M2 have information display portions M1a and M2a, angle display portions M1b and M2b, and position display portion M1c, the markings M1 and M2 may also represent other content, such as including at least one of the information display portions M1a and M2a, the angle display portions M1b and M2b, and the position display portion M1c.

[0053] Furthermore, in the above description, the coating agent C (coating area A1) is positioned to surround the mounting area A2 of the first part P1. However, since the coating agent C only needs to be provided in the area where the markings M1 and M2 (marking areas to be formed) are formed, the position of the coating agent C can be determined arbitrarily. For example, the coating agent C may be located only in the area where the markings M1 and M2 are formed, or it may be located in multiple separate areas on a single target surface P1a, P2a. Also, the target surfaces P1a, P2a on which the coating agent C is dispensed may be surfaces that do not include the mounting area A2, i.e., surfaces to which other parts cannot be attached. In addition, the coating agent C may be dispensed on multiple target surfaces P1a, P2a of a single first part P1 or second part P2. Furthermore, in the above description, the coating agent C is peeled off after assembly. However, for parts used as jigs, peeling off the coating agent C may be omitted. Furthermore, while the dispensing section 10 is preferably a dispenser that dispenses the coating agent C downwards, it may also be a spray or the like that dispenses the coating agent C in such a way that it spreads out as it goes downwards.

[0054] It should be noted that the present invention is not limited to the embodiments described above, and the components can be modified and implemented in practice without departing from the spirit of the invention. Furthermore, various inventions can be formed by appropriately combining the multiple components disclosed in the embodiments described above. For example, all the components shown in the embodiments may be combined as appropriate. It goes without saying that various modifications and applications are possible without departing from the spirit of the invention.
