Abstract
Description
[Technical field]
[0001] The present invention relates to a precut processing device. [Background technology]
[0002] It has been known that structural materials (processed parts) such as beams, columns, slats, and insulation materials used in buildings such as houses are cut in advance at a precut processing factory, reducing the amount of work required at the construction site, thereby efficiently manufacturing buildings. In the precut processing factory, structural materials are manufactured using a precut processing device, and information related to each structural material, such as letters and ink lines, is printed on the structural materials by a printing device.
[0003] In addition, many structural materials are transported to the construction site in a state where they are sorted into multiple packages, such as by the location of use, to facilitate work at the construction site. As a method for classifying the materials into multiple packages, sorting conditions based on openings and dividing wall surfaces into multiple parts have been proposed (for example, see Patent Documents 1 and 2). [Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2018-195019 A [Patent Document 2] Patent Publication No. 2022-019037 Summary of the Invention [Problem to be solved by the invention]
[0005] However, in the case of sorting conditions in which the opening or wall surface is divided into multiple parts, the number of structural materials contained in each package is reduced, but the number of packages is likely to increase. This may lead to problems such as time and effort required to find the necessary packages. In other words, there may still be room for improvement in the sorting conditions that can be used to sort and transport structural materials.
[0006] The present invention has been made to solve the above-mentioned problems, and has an object to provide a precut processing device that can suitably set sorting conditions that can be used for packaging processed parts. [Means for solving the problem]
[0007] To achieve this object, the precut processing device according to claim 1 comprises: A processing means for performing cutting processing; a printing means capable of printing on the processed parts processed by the processing means, The printing means is characterized in that it prints, as sorting information corresponding to predetermined sorting conditions, at least room information in which different information is set corresponding to each room space when the interior of a building is divided by interior walls, on the processed parts to which the room information has been set.
[0008] The precut processing device according to claim 2, A processing means for performing cutting processing; a transfer means capable of placing a plurality of processed parts processed by the processing means and transferring the processed parts to a part placement section provided at a plurality of locations; a control means for controlling the operation of the transport means to transport the processed parts so that the processed parts are sorted onto the plurality of part placement sections based on a predetermined sorting condition; The sorting conditions include at least a sorting condition based on room information in which different information is set corresponding to each room space when the interior of the building is divided by inner walls, The control means is configured to be capable of setting two or more processed parts corresponding to the room spaces in multiple locations having different room information to be cut from one material, to control the processing means to process the processed parts in a mixed order corresponding to the arrangement positions of the room spaces in multiple locations, and to execute control to transfer the processed processed parts to one of the multiple part mounting sections that is set corresponding to the room information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The precut processing device 100 is a device that prints sorting information on processed parts PT processed by a processing machine 1 and can transport the processed parts PT in a sorted state based on the sorting information to a plurality of part placement units 40. The precut processing device 100 of the present invention uses room information corresponding to each room space when the interior of a building is divided by inner walls as a sorting condition, and realizes control that can set a large number of processed parts with different sorting information to materials with good yield. Below, a basic configuration example of the precut processing device 100 will be described, followed by a configuration using room information and a configuration related to allocation of processed parts with good yield.
[0014] 1 is a schematic diagram showing the configuration of a precut processing apparatus 100. The precut processing apparatus 100 includes a processing machine 1 as processing means for processing a material (material wood), an upstream transfer device 2 and a downstream transfer device 3 as transfer means for transferring a structural material (hereinafter referred to as a processed part PT) processed by the processing machine 1, and a control device 9 for controlling the processing machine 1, the upstream transfer device 2, and the downstream transfer device 3.
[0015] The raw material is wood used as the material to be processed by the precut processing device 100, and is brought into the precut processing factory in a state where it has been processed to a certain cross-sectional shape (for example, a square shape with one side being 105 mm long or a square shape with one side being 120 mm long) and a predetermined length (for example, 3.8 m). A plurality of types of wood with different lengths and cross-sectional dimensions may be used as the raw material, and the processed part PT is efficiently manufactured by feeding the raw material according to the cross-sectional dimensions of the processed part PT into the precut processing device 100. For ease of understanding, an example of processing in which a large number of processed parts PT are manufactured using raw materials of a certain length and with a certain cross-sectional dimension will be described below.
[0016] The processing machine 1 is a device that performs cutting processing such as cutting a material and forming tenons and grooves for joining to other processed parts PT, and is equipped with cutting tools, a drive mechanism, etc., and also with a printing device 1a that can print letters and symbols on the processed parts PT. The upstream transfer device 2 and the downstream transfer device 3 are devices (transfer devices) that can transfer the processed parts PT in a state where they are sorted into a plurality of waiting positions (part placement section 40) based on sorting conditions so that packaging can be made easy. Note that in this embodiment, a case where two transfer devices 2 and 3 are combined will be described, but this is not limiting, and the transfer device may be configured by one integrated device, or three or more transfer devices may be combined.
[0017] The upstream transfer device 2 is a device that receives the processed parts PT manufactured by the processing machine 1 and separates the processed parts PT to be transferred to the downstream transfer device 3 from the processed parts PT not to be transferred to the downstream transfer device 3. A control device 9 controls whether the processed parts PT supported by the upstream conveyor 21 are advanced toward the downstream transfer device 3 side or toward the horizontal table 24 side. The processed parts PT that are not advanced toward the downstream transfer device 3 side and are made to wait on the horizontal table 24 are transferred to the horizontal table 24 by being pushed toward the inclined table 23 side by a pressing device 22, for example.
[0018] In addition, FIG. 1 illustrates a case in which the upstream conveyor 21 and the downstream conveyor 31 are arranged side by side with respect to the part placement section 40 of the downstream transfer device 3, the horizontal table 24 and the part placement section 40 are provided on one side (the front side of FIG. 1) of the traveling direction of the processed part PT transferred by these conveyors 21, 31, and the part placement section 40 and the horizontal table 24 are arranged side by side along the traveling direction of the processed part PT, but this is not limited to the above. The horizontal table 24 or another part placement section may also be provided on the opposite side (the back side of FIG. 1) of the part placement section 40 of the downstream transfer device 3 across the downstream conveyor 31, and waiting positions for the processed parts PT may be set on both sides intersecting the traveling direction of the upstream conveyor 21 and the downstream conveyor 31.
[0019] The horizontal table 24 and the part placement section 40 of the downstream transfer device 3 can be sorted using one or more sorting conditions, such as the unit of classification as a package or the length of the processed parts PT. The horizontal table 24 and some of the part placement sections 40 can also be used as a temporary storage area for the processed parts PT, and the processed parts PT can be transferred to the part placement section 40 to be finally transferred as a package after being temporarily placed thereon. The transfer of the processed parts PT after being temporarily placed may include a case where the worker manually performs the transfer, or a case where the precut processing device 100 performs the transfer under the control of the control device 9. For example, the operable range of the transfer mechanism 32 of the downstream transfer device 3 can be expanded to above the horizontal table 24, and the processed parts PT temporarily placed on the horizontal table 24 by the transfer mechanism 32 can be controlled to be transferred to the part placement section 40 of the downstream transfer device 3.
[0020] The downstream transfer device 3 is provided with a downstream conveyor 31 capable of receiving the processed parts PT transferred from the upstream transfer device 2 and transferring them linearly. The processed parts PT transferred by the downstream conveyor 31 are transferred to one of a plurality of part placement sections 40 by a transfer mechanism 32. The part placement section 40 is configured by arranging a large number of collection units 33 each having a support surface on which the processed parts PT can be placed one above the other. The transfer mechanism 32 may be any mechanism capable of transferring the processed parts PT transferred by the downstream conveyor 31 to the part placement section 40, and may be configured, for example, by a ceiling crane using a suction pad that hoists and moves the processed parts PT, or may be configured by a multi-joint robot.
[0021] The part placement units 40 are provided at a plurality of locations and are configured to form a plurality of waiting positions that are sorted for easy packing. Each part placement unit 40 is configured to be capable of placing a plurality of processed parts PT, and processed parts PT (hereinafter also referred to as "related parts group") associated by a predetermined sorting condition are placed on one part placement unit 40 in a state where they are grouped together. When one related parts group cannot be accommodated on one part placement unit 40, the control device 9 may include a control to place one related parts group on two or more part placement units 40. Two or more related parts groups may be placed on one part placement unit 40. For example, the placement of one related parts group on one part placement unit 40 may be started, and when the placement is completed, another related parts group may be placed on top of it, so that the processed parts PT are placed so that different related parts groups are lined up above each other.
[0022] The control device 9 controls the precut processing device 100, and controls the operation of the processing machine 1, the upstream transfer device 2, and the downstream transfer device 3 to produce processed parts PT from the input materials, and transfer the processed parts PT to the horizontal table 24 or the part placement unit 40 in a sorted state. The control device 9 can be configured, for example, by a personal computer, and is configured with a control unit 90 as a main body, a display unit 91 that outputs various data and the operating status of each device, and an input unit 92 such as a connection unit, a keyboard, and a mouse for inputting data. The control unit 90 is also configured with a storage device such as a ROM (IC chip) and RAM (magnetic disk or SSD) that store various programs and various data, a processing unit (CPU) that executes programs and performs arithmetic processing on various data, etc.
[0023] The control unit 90 stores a program for extracting, from the CAD data of the building input from the input unit 92, mutually identifiable information (hereinafter also referred to as individual identification information) for the number of processed parts PT required for production, and information regarding the processing required for each processed part PT (hereinafter also referred to as processing information). The individual identification information is composed of information including the location in the building where the processed parts PT are used, their length, cross-sectional size, and the type of the processed parts PT, and the extracted individual identification information is used to determine the horizontal stand 24 and the part placement unit 40 that will be the standby position after processing. The individual identification information is also used when the printer 1a prints print information based on the individual identification information onto the processed parts PT.
[0024] As one piece of individual identification information of each processed part PT, room information is stored in the control unit 90. The individual identification information including the room information may be configured to be stored in association with each processed part PT as part of a program for generating precut data, or a part of the individual identification information including the room information may be configured to be set by an operator to the processed part PT.
[0025] Next, the room information will be described mainly with reference to Fig. 2. Fig. 2(A) is a schematic diagram showing a part of the floor plan of the building CT, Fig. 2(B) is a schematic diagram showing a part of the elevation of the building CT, and Fig. 2(C) and (D) are diagrams showing examples of the contents of the printed information.
[0026] As shown in Fig. 2(A), a building CT often has an interior space surrounded by an exterior wall W1, which is divided into multiple room spaces by interior walls W2. Examples of room spaces include a living / dining / kitchen area (LDK), a bedroom, a space that combines a bathroom and toilet, and an entrance hall. Spaces such as stairs and corridors can also be identified as room spaces.
[0027] The horizontal outer periphery (exterior surface) of the room space is made up of an outer wall W1 and an inner wall W2, and the outer wall W1 can be constructed by attaching wall materials to the surface of a pillar material as a framework. The inner wall W2 that separates each room space can also be constructed by combining pillar materials and wall materials, and is not shown in FIG. 2(A). The room space can be set corresponding to a room space where the processed part PT, which is installed so as to be continuous on the vertical side of the building CT, is located at a corner of the outer periphery of the room space, and can also be set corresponding to a room space where the processed part PT is located at multiple points on the periphery (for example, a curved inner wall W2) without being limited to the corner of the periphery.
[0028] Furthermore, many structural materials are used on the periphery of the room space, such as the foundations installed on the foundation, the underlayment materials (fireworks, joists, joists, etc.) used under the floor surface, the boards and braces that make up the floor and ceiling surfaces, the rafters used on the upper side of the room space on the top floor, etc. Each of these structural materials is assigned room information corresponding to the room space in which it is located on the periphery, and each structural material is managed by the control device 9 using the room information.
[0029] 2(A) shows an example of managing processed parts PT using room information including the letters "A" for the entrance, "B" for the bathroom and toilet, "C" for the living / dining / kitchen area, and "D" for the bedroom. This allows the control device 9 to execute sorting based on the room information, making packaging easier, and also facilitating packaging and identification of structural materials used in close proximity, including structural materials manufactured by the precut processing device 100 or other processing devices.
[0030] 2(B) illustrates an elevation view of a building CT in which an entrance opening D1 and openings D2 and D3 constituting windows are installed on a wall. The processed part PT constituting the outer wall W1 of the entrance including the opening D1 is set with room information that combines character information indicating the room information (e.g., "R"), character information corresponding to the entrance (e.g., "A"), and character information corresponding to the outer wall W1 (e.g., "SK"), and is managed as individual identification information by the control device 9.
[0031] 2(C) shows an example of a case where room information is included in the print information printed on the processed part PT. The room information includes the letter "R" indicating that it is room information, the letter "C" corresponding to the living / dining / kitchen room, and the letter "SK" corresponding to the exterior wall W1, and is also combined with the letter "1" (number).
[0032] Here, for the exterior wall W1 and the interior wall W2, at a construction site, the processed parts PT related to the exterior wall W1 may be assembled first, so it is preferable to enable selection of separate packaging for room information that includes characters corresponding to the exterior wall W1 (e.g., "SK") and that does not include such characters (e.g., "UK" corresponding to the interior wall W2). That is, it is preferable to enable setting of processed parts PT with common exterior wall identification information as a sorting condition based on individual identification information such as information corresponding to the exterior wall W1 included in the room information (hereinafter referred to as "exterior wall identification information"). In detail, it is preferable to include in the control device 9 a program that can execute control of transporting the processed parts PT in a sorted state to a plurality of part placement units 40 using the exterior wall identification information and printing the exterior wall identification information on the processed parts PT.
[0033] As for the exterior wall W1, as shown in Fig. 2(A), within the perimeter of the room space of the building CT, there are cases where an exterior wall W1 on the entrance side (lower side of Fig. 2(A)) and an exterior wall W1 on the opposite side (upper side of Fig. 2(A)) are formed, such as the exterior wall W1 of an LDK. In this way, when the components of the two exterior walls W1 are spaced apart, it may be preferable to package them separately. For this reason, it is preferable to include directional information indicating the direction of the building CT in the room information, and Fig. 2(C) shows an example in which the number "1" is included as directional information in the room information.
[0034] The number "1" as the direction information can be information indicating one direction in the building CT. If the entrance of the building CT is set to face south, the number "1" is used as a character indicating the exterior wall W1 located on the south side in the room space. For the opposite side (for example, the north side), other information (for example, the number "2") is used. For a direction other than the direction indicated by the information "1" and "2" (horizontal direction in FIG. 2(A)), room information can be set using other direction information (for example, the letters "a" and "b"). By managing the room information using the direction information in this way, when the exterior walls W1 are located in multiple directions in one room space, it is possible to easily manage the processed parts PT, for example, by packaging them separately.
[0035] FIG. 2(C) illustrates an example of a case in which the individual identification information includes, in addition to the room information, type information consisting of characters indicating the type of the processed part PT (e.g., "partition stud"), floor information consisting of characters indicating the floor (e.g., "1" indicating the first floor), position information consisting of a number indicating the location where the processed part PT is used (e.g., "nu / 6"), and length information consisting of a number indicating the length of the processed part PT (e.g., "2000"). The individual identification information (printed information) printed on the processed part PT is not limited to including all of the information shown in the examples, and may use part of the information shown in the examples, or may combine other information in addition to the information shown in the examples.
[0036] The room information may use predetermined characters (numbers, alphabets, etc.), and room information may be set for each room space in alphabetical or numerical order. In addition, the room information may use kanji characters or characters such as "LDK" or "Entrance", and may include symbols and figures corresponding to each room, and may include figures corresponding to the shape, position, and use of the room. The room information may be set, for example, when inputting a floor plan using a design CAD. The design CAD may include a control for assigning room information (identification information) such as numbers, letters, or symbols such as A, B, C, or 1, 2, 3 to each room space, or a function for setting room information manually by a person inputting the design CAD may be included in the design CAD.
[0037] FIG. 2(D) illustrates another embodiment of the printed information including room information. Specifically, the room information is displayed as "south exterior wall of living room" to indicate the name, direction, and location of use in characters. Also, the information (opening information) is included by displaying "RC1SKD" and using the last letter "D" to indicate that the processed part PT is used around the opening. Also, the information is displayed as "RCa interior wall" to indicate that the interior wall is in the direction corresponding to "a" for the letter "RC" corresponding to the room information of "LDK". Furthermore, the information is displayed as "RABC interior wall - standing pillar" to indicate that the processed part PT (PT1 in FIG. 2(A)) is used in the boundary part where the entrance corresponding to "A", the bathroom / toilet corresponding to "B", and the LDK corresponding to "C" are adjacent to each other. Also, FIG. 2(A) illustrates an example in which the interior wall W2 located in the boundary part between two room spaces can be identified by room information located on both sides of the boundary part such as "RAB" and "RBC". The display of the room information may be any of those described above, or may be a different display, or may be a combination of a plurality of displays of room information.
[0038] In this way, the precut processing device 100 can print print information including room information as sorting information corresponding to the sorting conditions on the processed parts PT processed by the processing machine 1. Furthermore, the precut processing device 100 can transfer the processed parts PT to a plurality of different waiting positions (horizontal platform 24, a plurality of part placement units 40) based on the room information under the control of the control device 9. This allows room information corresponding to each room space when the interior of the building CT is partitioned by the inner wall W2 to be used as a sorting condition. In this case, compared to the case where a wall surface or an opening is used, room information common to a large number of processed parts PT installed in close positions can be printed, and packaging based on the room information can also be performed. Therefore, it is possible to efficiently identify the necessary structural materials from a large number of structural materials.
[0039] Next, a configuration for allocating processed parts PT with a high yield will be described with reference to Figs. 3 to 5. The processing machine 1 performs processing on a material based on processing information (precut data) generated by CAD to manufacture processed parts PT. In processing by this processing machine 1, not only one processed part PT is manufactured from one piece of material, but also other processed parts PT may be manufactured using scrap material remaining after processing one processed part PT. By reducing the amount of leftover material after the processed parts PT are manufactured from the material, processing with a high yield can be performed. The combination of processed parts PT manufactured from one piece of material can be determined using a parts manufacturing sorting process (S10) as a program of the control device 9.
[0040] 3 is a flow chart showing the part manufacturing sorting process S10 of the precut processing apparatus 100 by the control device 9. The control of the precut processing apparatus 100 first involves a target part selection process S20 for selecting parts to be processed (target parts). The selection of the target parts can be performed by having the control device 9 read the precut data and displaying the target parts for processing on the display unit 91 so that the worker can select them.
[0041] Here, the target parts to be processed can be all parts in a building, or parts included in each part such as each floor or the outer wall W1 and the inner wall W2, and it is preferable to configure the system so that the worker can select the target parts to be processed. In addition, it is preferable to set the target parts to be processed to include a large number of parts that can be sorted into multiple part placement units 40 according to the sorting conditions, which can increase the yield. For example, it is preferable to set the target parts to include the number of parts to be sorted to 5 or more so that they can be sorted into 5 or more part placement units 40, and it is more preferable to set the target parts to have the number of parts to be sorted to 10 or more.
[0042] In addition, the downstream transfer device 3 is provided with, for example, 18 part placement units 40, and when target parts are selected with a sorting number of 18 or less, the processed parts PT can be directly transferred to one of the part placement units 40 and sorted without using a temporary storage area. In addition, the sorting number of parts to be processed does not necessarily need to be set to be less than the number of part placement units 40, and may be greater than the number of part placement units 40. In this case, it is preferable that each part placement unit 40 is provided with an alarm device 34 (see FIG. 1) that notifies the completion of placement of all the processed parts PT to be placed by turning on a lamp or outputting a sound, etc., and the worker confirms that placement is completed by the notification from the alarm device 34, and after placement is completed, the worker packs the parts and moves one related part group from the part placement unit 40, thereby setting an empty part placement unit 40, and setting an unset sorting number thereto to set a new sorting position.
[0043] Once the parts to be processed are selected, a combination of processed parts PT to be assigned to the material is set as a material setting process S30. Since the downstream transfer device 3 is provided with multiple part placement units 40, the processed parts PT can be sorted into a large number of categories using sorting information. Therefore, even if a combination of processed parts PT cut out from a single piece of material includes parts that will be used at work locations far away on a construction site, they can be transferred to the part placement units 40 that are individually set as packaging units. The combination of processed parts PT can be assigned manually by an operator, but is preferably determined using a program in the control device 9, and the control content using the program will be described with reference to FIG. 4.
[0044] 4 is a flowchart showing the material setting process S30. When the material setting process S30 starts, first, the parts to be processed are sorted in order of length (S31). Thereafter, if there are parts of the same length, the parts are sorted in order of sorting number (S32). The sorting numbers may be prioritized by the worker, or a program for generating precut data or a program for designing a building CAD may include a program for setting the priority order of the sorting numbers. When setting by the program, the priority order may be set based on the order in which the house is constructed (for example, in the case of a multi-story house, the lower side is given priority) or the layout position.
[0045] After the process of S32, a new material is set for the first target part among the target parts for which a material has not been set (S33). When using materials with the same cross-sectional shape and the same length, this material setting can be done, for example, by setting material numbers in order starting from 1 and allocating a target part to each material number. When the material includes some materials whose length is different from the standard, in the process of S33, the target part with the longest length is set with priority from among the target parts that can be processed within the length range of the material for which the target part is set. Note that for materials with non-standard lengths, an input screen may be displayed that allows the worker to set the target parts individually, making it possible to set the target parts.
[0046] After the process of S33, the remaining length of the material remaining when the set target part is machined is calculated (S34), and it is determined whether there is a target part that can be manufactured with that remaining length (S35). If it is determined in the process of S35 that there is a target part that can be manufactured (S35: Y), a material number is set for the first target part among the target parts that can be manufactured (S36), and the process returns to S34 and is repeated.
[0047] If it is determined in the process of S35 that there are no target parts that can be manufactured (S35: N), it is determined whether there are any target parts for which a material has not been set (S37), and if there is a corresponding target part (S37: Y), the process returns to the process of S33, the material number is updated by one, and the target part is assigned to the next material (S33). By performing the material setting process S30 in this way, a target part for processing can be set for each material.
[0048] After the material setting process S30, as shown in Fig. 3, a processing transfer process S40 is performed in which the processing machine 1 is controlled to manufacture processed parts PT from the materials, and then the transfer devices 2, 3 are controlled to transfer the processed parts PT to a part placement unit 40 that corresponds to the sorting conditions. The processing transfer process S40 includes a process of setting the part placement unit 40 that corresponds to the sorting conditions, and the process contents will be described with reference to Fig. 5.
[0049] 5 is a flowchart showing the processing transfer process S40. In the processing transfer process S40, first, the processing order of the materials is determined. The processing order of the materials is determined so that priority is given to processing of materials including those with small sorting numbers. Specifically, the processing order of the materials is rearranged so that materials (material numbers) including target parts with small sorting numbers are positioned first (S41). This allows processed parts PT to be manufactured with priority given to those with small sorting numbers, and makes it easier to complete packaging in the order of the sorting numbers.
[0050] After the process of S41, materials (material numbers) containing target parts with the same sorting number are rearranged in order of length so that the longer ones are processed first (S42). By manufacturing processed parts PT with priority given to the longer ones, the longer processed parts PT are more likely to be placed on the lower side on the part placement unit 40, so that the package shape when packed is more stable and the work of switching the processed parts PT up and down on the part placement unit 40 can be reduced.
[0051] When the processing order of the materials is determined in the processes of S41 and S42, processing of the unprocessed target parts is started according to the processing order of the materials (S43), and it is determined whether a sorting position is set for the target parts to be manufactured with the material number for which processing is to be performed (S44). If the part placement unit 40 for sorting the processed parts PT is not set as a sorting position in the process of S44 (S44: N), the part placement unit 40 is set as a sorting position for the sorting number of the target parts for which a sorting position is not set (S45). For example, the part placement unit 40 is set as a sorting position from the back side along the transfer direction of the processed parts PT by the transfer device. If it is determined that a sorting position is set in the process of S44 (S44: Y), the process of S45 is skipped and the process proceeds to S46.
[0052] In the process of S46, the processed target parts (processed parts PT) are transported to the sorting position (S46), and if the processing and transport of all the target parts are not completed (S47: N), the process returns to S43 and executes the processing. When the processing and transport of all the target parts are completed (S47: Y), the processing and transport process S40 ends. Note that, for ease of understanding, the flowchart in FIG. 5 illustrates a process in which the target parts are processed one by one in sequence and then transported, and then processing of another target part is started, but this is not limiting, and it is preferable to perform multiple processes in parallel to increase the productivity of the precut processing device 100. For example, the processing process of S43 and the transport process of S46 may be controlled to proceed in parallel for multiple processed parts PT.
[0053] Next, a specific example of the above-mentioned processed part manufacturing process executed by the control device 9 will be described with reference to Fig. 6 to Fig. 8. Fig. 6 is a diagram illustrating the process of rearranging the target parts by the material setting process S30, and Fig. 7 is a diagram illustrating a situation in which the target parts are assigned to multiple materials by the material setting process S30 and the processing order is determined by the processing transfer process S40. Fig. 8 is a diagram illustrating a situation in which the sorting positions are set for the sorting numbers.
[0054] In Fig. 6(A), sorting numbers 1 to 8 are set, and eight types of room information such as "RA" and "RC1" are set as room information corresponding to each room space shown in Fig. 2(A) so as to correspond to each sorting number. Although an example is shown in which only one or two parts are set as the target parts for processing for each sorting number, in reality, many target parts such as five to ten parts are set. In addition, an example is shown in which a structural material is manufactured for the exterior wall W1 as the room information.
[0055] Room information "RA" for sorting number 1 illustrates an example in which target parts corresponding to the exterior wall W1 around the entrance, target parts used for the exterior wall W1 on the south side (lower side of Figure 2(A)) and west side (left side of Figure 2(A)), are sorted using common room information. When the section is shorter than the exterior walls W1 of other room spaces, such as the perimeter of the room space of room information "RA", the number of processed parts PT used will be fewer. In such cases, it is preferable to use room information that does not include directional information, which prevents the number of sorts from increasing excessively and allows sorting to be done so that processed parts PT used nearby are grouped together.
[0056] When the part manufacturing sorting process S10 (see FIG. 3) is performed, various information including the material length and sorting number for the target parts to be processed selected by the target part selection process S20 (see FIG. 3) is stored in the control device 9 as shown in FIG. 6(B). In FIG. 6(B) and FIG. 6(C), elongated graphic data representing the material length is shown in schematic form corresponding to the length of each target part. When the material setting process S30 is performed by the control device 9, the multiple target parts are rearranged in order of length using the material length data as shown in FIG. 6(C). In addition, parts of the same length are rearranged in order of their sorting numbers.
[0057] After that, the material setting process S30 assigns target parts to a plurality of materials as shown in FIG. 7. Specifically, among the target parts that have been rearranged as shown in FIG. 6(C), they are assigned to materials in order starting from the first one for which a material has not been set. For example, if the length of the material is 3800 mm, the material with the first material number (material 1) is assigned No. 1 as a target part with a material length of 2000 mm. Since the remaining length after manufacturing No. 1 is "3800-2000=1800", a target part that can be manufactured in 1800 mm is selected. Note that it is preferable to calculate the remaining length not by subtracting only the material length (length) of the target part, but by using a material length that takes into account the length to be cut in the cutting process (for example, the cutting allowance of the circular saw) (for example, the length obtained by adding 10 mm to the material length of the target part). In addition, in the following explanation and in Figures 7 and 8, for ease of understanding, the sorting number is indicated in parentheses after the part number. For example, No. 1(1) indicates that the sorting number is 1.
[0058] Here, when selecting target parts to be assigned to materials, it is possible to set target parts from among the target parts using only their length, but it is also possible to select them including other conditions. Figure 7 shows an example of a case where the range of the same sorting material is used to select target parts. The range of the same sorting material determines the upper limit of the number of different sorting numbers and the range of types when target parts with different sorting numbers are assigned to materials. For example, the difference in the size of the sorting numbers can be set to 5 or less. In addition, the type can be set to select target parts limited to only those with the same or similar types in terms of the location of use, such as exterior and interior walls, or one layer and two layers, or the type in terms of use, such as openings and flooring.
[0059] The process using the sorting same material range can be included as part of the process of S35 of the material setting process S30 (see Fig. 4). As a result, in the process of setting another target part for the remaining length (the process of S36 in Fig. 4), it is possible to set another target part with a long length for which cutting processing has not been set, from among a plurality of target parts included within an upper limit range set by a predetermined number as a range with different sorting numbers as sorting information or within an upper limit range set by a predetermined condition, as a processing target for one material.
[0060] By using the sorting range of the same material, processed parts PT with similar sorting numbers or processed parts PT of the same or similar type are more likely to be manufactured from the same material. Therefore, for example, it is possible to prioritize the manufacture of processed parts PT with similar sorting numbers compared to the case where only the length is used as a condition. In this case, it is possible to easily complete the manufacture of processed parts PT at the part placement unit 40 and transition to a state where packaging is possible, and since packaging work can be efficiently carried out even if the number of part placement units 40 is limited, it is possible to reduce the number of situations where the precut processing device 100 stops operating.
[0061] In FIG. 6(C), target parts with a remaining length of 1800 mm that can be manufactured include No. 2 (6), No. 3 (6), and No. 4 (7), which are target parts with a material length of 1500 mm. However, these target parts have sorting numbers 6 and 7, which do not satisfy the condition of the same material sorting range within 5 (for sorting number 1, up to sorting number 5). In this case, the next longest parts with a material length of 1000 mm, No. 6 (5) and No. 7 (4), become selection candidates, and since sorting numbers 4 and 5 satisfy the condition of the same material sorting range, No. 7 (4), which has the smallest sorting number, is assigned to material number 1 (material 1). Similarly, target parts are assigned to materials 2 to 5, and the material setting process S30 is completed.
[0062] When the material setting process S30 is completed, the processing transfer process S40 is executed, and the processing order of the materials 1 to 5 is set based on the material length and sorting number of the target parts. The processing order is set by giving priority to the target parts with the smallest sorting number, followed by those with the longest length. When the processing order is set, processing is performed on each material according to the set processing order. If the sorting positions of the target parts have not been set at the timing when this processing starts, as shown in FIG. 8, the sorting positions are set for the sorting numbers corresponding to the sorting information in order from the tip side (left side in FIG. 8) of the transfer direction (arrow direction in FIG. 8) of the processed parts PT on the downstream conveyor 31, as shown in FIG. 8. The setting method and timing of this sorting position are not limited to this, and other methods can be applied. For example, the sorting positions may be specified in advance by the worker, or the sorting positions may be arranged in the order of the sorting numbers.
[0063] In this way, the material setting process S30 includes a process as a long part setting means for setting a long part for which cutting is not set as a processing target for one material from among a large number of target parts (machined parts) including processed parts PT with different sorting information and the same cross-sectional dimensions (processing of S33 in FIG. 4), and a process as a different part setting means for setting another long part for which cutting is not set as a processing target for one material from among multiple processed parts with different sorting numbers as sorting information for the remaining part when the processed part set by the long part setting means is cut from the material (processing of S36 in FIG. 4). Therefore, it is possible to set two or more processed parts with different sorting information to be cut from one material, and it is possible to preferentially set a long processed part PT from multiple processed parts with different sorting information as a processing target.
[0064] This process of setting the processing target for the material by giving priority to the long processing target parts can avoid setting a large number of short parts to the material first. Since short parts can often be set either individually or in combination with multiple parts based on the remaining length of the material, the degree of freedom in setting them based on the remaining length of the material is higher than if long parts were left unset. Therefore, by executing the material setting process S30, which basically gives priority to long parts and sets them to the material, on the precut processing device 100, it is possible to easily set the processing target while also making it easier to perform processing with a high yield.
[0065] Furthermore, the processing transfer process S40 includes a process as a processing order determination means (processes of S41 and S42 in FIG. 5) that determines the processing order of a plurality of materials after the process of setting a plurality of processing target parts with different sorting information as processing targets for a plurality of materials is completed. Therefore, the processing order of materials is set based on the sorting information (sorting number), and it is possible to prioritize some sorting positions so that processed parts PT are gathered together and made ready for packaging.
[0066] The processing transfer process S40 also includes a process for setting the placement positions of the component placement units 40 with respect to the sorting information based on the processing order of the processed parts PT, which is determined by the processing order of the materials (processings of S44 and S45 in FIG. 5). Since the placement positions of the component placement units 40 can be determined by giving priority to parts with earlier processing orders, the possibility of needing a temporary placement space is reduced, and the limited number of component placement units 40 can be used efficiently.
[0067] The control device 9 can also be set to cut two or more processed parts PT corresponding to a plurality of room spaces having different room information from one material, and can control the processing machine 1 to process the processed parts PT in a mixed order corresponding to the arrangement positions of the plurality of room spaces, and can execute control to transfer the processed processed parts PT to one of the plurality of part placement units 40 that is set corresponding to the room information. This makes it possible to pack based on the room information while facilitating processing with a high yield rate.
[0068] The present invention is not limited to the above-described embodiment, and it can be easily imagined that various improvements and modifications are possible within the scope of the present invention, and for example, the present invention may be modified as described below.
[0069] In the above embodiment, the processing machine 1 has been described as being configured to process rod-shaped wood, but it may also be configured to process other materials such as metal or resin, or to process materials of shapes other than rod-shaped. For example, it may be configured to process a plate-shaped material to manufacture plate-shaped parts, print information on one or more of the manufactured plate-shaped parts, and place them in a sorted state on each of the part mounting sections 40.
[0070] In addition, a control device 9 in which a program for a precut processing device including a material setting process S30 and a processing transfer process S40 is stored may be attached to a conventional precut processing device, or a precut processing device 100 corresponding to an embodiment of the present invention may be configured by installing a program for a precut processing device in the control device of a conventional precut processing device.
