Let M be a natural number less than or equal to n and greater than or equal to 2. Based on M of the above first processing information (two pieces of first processing information, first processing information 81 and first processing information 82) out of the n+1 pieces of first processing information, first processing plan information (first processing plan information 91) is generated for successively generating M types of processed products (two types of processed products, processed product 81A and processed product 82A) based on each of the M pieces of first processing information.

When the generation of one of the two types of workpieces (workpiece 82A, workpiece 83A) generated by the operation of the processing unit based on the second processing plan information described above is completed, and the generation of the other of the two types of workpieces is not yet completed, a third processing plan information (third processing plan information 93) is generated for the continuous generation of the incomplete workpiece (workpiece 83A) and the workpiece (workpiece 84A) based on the remaining number (remaining number Y) of the incomplete workpiece (workpiece 83A), the first processing information (first processing information 83) corresponding to the incomplete workpiece, and one of the first processing information (first processing information 84) from the n+1 pieces of first processing information excluding the M pieces of first processing information and the specific processing information described above, based on the remaining number (remaining number Y) of the incomplete workpiece (workpiece 83A), the first processing information (first processing information 83) corresponding to the incomplete workpiece, and one of the first processing information (first processing information 84) excluding the M pieces of first processing information and the specific processing information described above, A control device for a rebar processing machine that operates the processing unit based on the above-mentioned processing plan information (third-party processing plan).

[0009] (3) A control device for a rebar processing machine as described in (1) or (2), The above processor is Second processing information (second processing information 85) is obtained which defines the cutting dimensions for the remaining material of a length that makes it impossible to produce a workpiece based on the first processing information described above.

A rebar processing plan generation program that causes a processor to execute a step to generate second processing plan information for continuously generating the incomplete workpiece and the workpiece based on the first processing information, when the generation of a part of the M-type workpiece is completed by the operation of the processing section of a rebar processing machine that can be operated based on the first processing plan information described above, and the generation of the other part of the M-type workpiece is not yet completed, based on the remaining number of the incomplete workpiece, the first processing information corresponding to the other part, and the first processing information excluding the M pieces of the n+1 pieces of the first processing information, wherein the second processing plan information is generated for continuously generating the incomplete workpiece and the workpiece based on the first processing information. [Effects of the Invention]

[0011] According to (1) and (4), first processing plan information is generated based on a portion (M pieces) of the n+1 pieces of first processing information, and processing is started based on this first processing plan information. Therefore, compared to the case where first processing plan information is generated based on all of the n+1 pieces of first processing information, the load required to generate the first processing plan information can be reduced, and the time until processing can be started can be shortened. After processing based on the first processing plan information has started, second processing plan information is generated according to the progress of processing, and processing is carried out based on this second processing plan information. In this way, processing plan information can be appropriately updated according to the progress of processing, so the time until the production of all processed products can be shortened. In addition, by updating the processing plan according to the progress, it is also possible to reduce the amount of waste material that is discarded.

[0012] According to (2), the first processing plan information, the second processing plan information, and the third processing plan information are each generated based on two first processing information pieces. Therefore, the processing load for generating the first processing plan information, the second processing plan information, and the third processing plan information can be reduced.

[0013] According to (3), since the first processing plan information is generated based on the second processing information, it is possible to achieve both effective utilization of leftover materials and improved efficiency in the production of processed products.

[0014] [Figure 1] FIG. 1 is a schematic diagram showing a schematic configuration of a reinforcing bar processing machine 100. [Figure 2] FIG. 2 is a schematic diagram for explaining the processing content of the control unit 50.

Mode for Carrying Out the Invention

[0015] FIG. 1 is a schematic diagram showing a schematic configuration of a reinforcing bar processing machine 100. The reinforcing bar processing machine 100 performs processing of reinforcing bars including cutting. The reinforcing bar processing machine 100 may only perform cutting of reinforcing bars, or may perform cutting and bending of reinforcing bars. When performing cutting and bending of reinforcing bars, the order of cutting and bending may be either first. Hereinafter, the reinforcing bar processing machine 100 will be described as performing cutting and bending of reinforcing bars.

[0016] The reinforcing bar processing machine 100 includes a reinforcing bar standby unit 10 for waiting for the reinforcing bar before processing, a processing unit 20 for performing processing of the reinforcing bar (in this example, cutting and bending), a reinforcing bar storage unit 30 for storing the processed product of the reinforcing bar obtained by the processing in the processing unit 20, a supply unit 40 for supplying the reinforcing bar waiting in the reinforcing bar standby unit 10 to the processing unit 20, a control unit 50 for overall control of the entire reinforcing bar processing machine 100, and an operation unit 60. The reinforcing bar storage unit 30 may be provided with a mechanism capable of sorting according to the type of processed product (length, bending shape, etc.). The processing unit 20 and the supply unit 40 constitute a processing unit for performing processing of reinforcing bars including cutting.

[0017] The control unit 50 is a form of a control device and includes a processor such as a CPU (Central Processing Unit) and a memory. The control unit 50 performs various processes by the processor executing a program. The processor of the control unit 50 may be configured by a single one or may be configured by a plurality of ones. When the processor of the control unit 50 is configured by a plurality of ones, these plurality of processors do not need to be provided in the same place. The control unit 50 only needs to be in a place where it can communicate with the control target of the reinforcing bar processing machine 100, and may be provided in a device different from the reinforcing bar processing machine 100.

[0018] The operation unit 60 is an interface for inputting various types of information and various operation instructions. The operation unit 60 includes a touch panel integrated with the display device, a keyboard, buttons, or a mouse. Information input from the operation unit 60 is transmitted to the control unit 50. The control unit 50 and the operation unit 60 may be composed of, for example, a general-purpose smartphone or tablet terminal.

[0019] The control unit 50 controls the machining processing unit 20 and the supply unit 40 in order to continuously generate multiple types of workpieces based on information input from the user.

[0020] Figure 2 is a schematic diagram illustrating the processing of the control unit 50. As a preparatory step before starting processing, the user inputs the necessary information (hereinafter referred to as "first processing information") for generating each of several types of workpieces using the operation unit 60. The first processing information defines the processing details, including the cutting dimensions of the reinforcing bars, the bending dimensions of the reinforcing bars (bending position, bending angle, etc.), and the number of processing units (total number of workpieces required). If the processing unit 20 only performs cutting, the first processing information does not include information on the bending dimensions of the reinforcing bars.

[0021] Figure 2 shows an example in which a user inputs four pieces of first processing information (first processing information 81, first processing information 82, first processing information 83, and first processing information 84) corresponding to four types of workpieces in order to generate those four types of workpieces. The first processing information 81, first processing information 82, first processing information 83, and first processing information 84 are stored in the memory of the control unit 50.

[0022] Hereinafter, a workpiece produced by processing based on the first processing information 81 will be referred to as workpiece 81A, a workpiece produced by processing based on the first processing information 82 will be referred to as workpiece 82A, a workpiece produced by processing based on the first processing information 83 will be referred to as workpiece 83A, and a workpiece produced by processing based on the first processing information 84 will be referred to as workpiece 84A.

[0023] The user can set the processing priority for each of the four first processing information by operating the control unit 60. In the following, it is assumed that the priority is set in the order of first processing information 81 > first processing information 82 > first processing information 83 > first processing information 84.

[0024] The rebar processing machine 100 is equipped with a trimming function that cuts excess material (hereinafter referred to as "excess material") to a uniform length so that it can be used for other purposes when, as a result of generating multiple workpieces from a single standard-length rebar, excess material of a length that makes it impossible to generate workpieces based on the first processing information is generated.

[0025] When the user utilizes this trimming function, they input second processing information, which specifies the cutting dimensions for excess material generated during continuous processing, via the operation unit 60. Figure 2 shows an example where the user has input the second processing information 85. The second processing information 85 is stored in the memory of the control unit 50.

[0026] In addition, the user inputs information about the reinforcing bars to be placed in the reinforcing bar waiting area 10, such as standard length, diameter, and type of reinforcing bar, using the operation unit 60. Figure 2 shows an example in which the user has inputted reinforcing bar information 86. The reinforcing bar information 86 is stored in the memory of the control unit 50.

[0027] In the rebar processing machine 100, when processing is performed on a standard-length rebar based on the first processing information, the remaining material obtained after processing is of a length that allows for the creation of a workpiece based on the first processing information, and this process is repeated on the remaining material. Let's consider the case where, as a result of multiple processings on a standard-length rebar, surplus material is obtained. In this case, if the length of the surplus material exceeds the length specified in the second processing information 85, the surplus material is cut to the length specified in the second processing information 85, and a rebar of that length is stored in the rebar storage section 30. If the length of the surplus material is less than the length specified in the second processing information 85, the surplus material is discarded without being cut. After that, a new standard-length rebar is supplied to the processing section 20, and processing is performed on that rebar.

[0028] When the control unit 50 receives an instruction to create a processing plan by pressing the processing preparation button included in the operation unit 60, it retrieves the first processing information 81, first processing information 82, first processing information 83, first processing information 84, second processing information 85, and rebar information 86 from memory.

[0029] Next, the control unit 50 makes various settings of the processing unit 20 and the supply unit 40 in accordance with the rebar information 86 so that processing suitable for the rebar to be processed can be performed.

[0030] Next, the control unit 50 selects M of the first processing information 81, 82, 83, and 84 in order of priority, starting with the highest priority. M is a natural number greater than or equal to 2, and less than or equal to the number of acquired first processing information items minus 1. In this case, since 4 first processing information items were acquired, M will be "2" or "3". As an example, if 3 first processing information items were acquired, M will be "2". As another example, if 5 first processing information items were acquired, M will be "2", "3", or "4".

[0031] Thus, when the control unit 50 acquires n+1 pieces of first processing information, where n is a natural number of 2 or greater, it selects n or fewer pieces, and at least two pieces, from the acquired n+1 pieces of first processing information, in order of the highest priority set. In the example in Figure 2, n=3. The case where M=2 will be explained below. In the case of M=2, first processing information 81 and first processing information 82 are selected.

[0032] Next, the control unit 50 generates first processing plan information 91 for successively generating a workpiece 81A based on the first processing information 81 and a workpiece 82A based on the first processing information 82, based on the selected first processing information 81 and first processing information 82, second processing information 85 and rebar information 86.

[0033] The control unit 50 sets the processing priority according to the priority set for the first processing information in the order of (processing based on first processing information 81) > (processing based on first processing information 82) > (trimming of surplus material), and then determines the number of times and the order in which processing based on the first processing information 81 and first processing information 82 will be performed on the standard length reinforcing bars so that the length of the surplus material will be as short as possible. Furthermore, for the surplus material obtained as a result of these processing, the control unit 50 determines the number of times trimming will be performed so that the maximum number of reinforcing bars of the length specified in the second processing information 85 can be obtained. In this way, the first processing plan information 91 is generated.

[0034] While not limited to this, as an example, the first processing plan information 91 specifies that, for a standard-length reinforcing bar, processing based on the first processing information is performed three times, followed by processing based on the second processing information once, and finally, the surplus material is cut once, thereby obtaining two processed parts 81A, one processed part 82A, and one piece of trimmed surplus material, all in a continuous process.

[0035] If the user has not entered the second processing information 85, the control unit 50 generates first processing plan information 91 for successively generating processed products based on the first processing information 81 and first processing information 82, respectively, based on the selected first processing information 81 and first processing information 82 and the rebar information 86.

[0036] In this case, the control unit 50 can determine the processing priority order according to the priority set for the first processing information, in the order of (processing based on the first processing information 81) > (processing based on the first processing information 82), and then determine the number of times and the order in which processing based on the first processing information 81 and the first processing information 82 will be performed on the standard length reinforcing bars so as to minimize the length of surplus material.

[0037] Next, when the control unit 50 receives a processing start instruction by pressing the processing start button included in the operation unit 60, it activates the processing processing unit 20 and the supply unit 40 based on the generated first processing plan information 91 to start processing the reinforcing bars in accordance with the first processing plan information 91.

[0038] As the reinforcing bars are processed according to the first processing plan information 91, depending on the content of the first processing plan information 91, it is possible that the generation of one of the workpieces 81A or 82A may be completed first. For example, consider the case where the generation of workpiece 81A is completed, but the generation of workpiece 82A is not yet complete. In this example, the control unit 50 executes the processing plan information update process when the generation of workpiece 81A is completed.

[0039] In this update process, the control unit 50 subtracts the number of workpieces 82A that have been produced up to the present from the number of processing steps included in the first processing information 82 to derive the remaining number of workpieces 82A to be produced X. The control unit 50 also selects one of the first processing information 83 and first processing information 84 with the highest set priority from the first processing information 81, first processing information 82, first processing information 83, and first processing information 84 that have been obtained from memory, excluding those that have already been selected. In this case, first processing information 83 is selected.

[0040] Then, the control unit 50 generates a second processing plan information 92 for successively generating the remaining X workpiece 82A and the workpiece 83A based on the first processing information 83, based on the remaining X, information other than the number of processing steps included in the first processing information 82 corresponding to the workpiece 82A, the first processing information 83 selected above, the second processing information 85, and the rebar information 86.

[0041] For example, the control unit 50 sets the processing priority in the order of (processing based on the first processing information 82) > (processing based on the first processing information 83) > (trimming of surplus material), and then determines the number of times and the order in which processing based on the first processing information 82 and the first processing information 83, respectively, is performed on the standard-length reinforcing bars so that the length of the surplus material is minimized. Furthermore, for the surplus material obtained as a result of these processes, the control unit 50 determines the number of times trimming is performed so that the maximum number of reinforcing bars of the length specified in the second processing information 85 is obtained. In this way, the second processing plan information 92 is generated.

[0042] When the control unit 50 generates the second processing plan information 92, it activates the processing processing unit 20 and the supply unit 40 based on this information to start processing the reinforcing bars according to the second processing plan information 92.

[0043] As the reinforcing bars are processed according to the second processing plan information 92, depending on the content of the second processing plan information 92, it is possible that the generation of one of the workpieces 82A or 83A may be completed first. For example, consider the case where the generation of workpiece 82A is completed, but the generation of workpiece 83A is not yet complete. In this example, the control unit 50 executes the processing plan information update process when the generation of the remaining X number of workpieces 82A is completed.

[0044] In this update process, the control unit 50 subtracts the number of workpieces 83A that have been produced up to the present from the number of processing steps included in the first processing information 83 to derive the remaining number Y of workpieces 83A that should be produced from now on. The control unit 50 also selects the first processing information 84 from the first processing information 81, first processing information 82, first processing information 83, and first processing information 84 that have been obtained from memory, excluding those that have already been selected.

[0045] Then, the control unit 50 generates a third processing plan information 93 for successively generating a workpiece 83A of the remaining number Y and a workpiece 84A based on the first processing information 84, based on the remaining number Y, information other than the number of processing units included in the first processing information 83 corresponding to the workpiece 83A, the first processing information 84 selected above, the second processing information 85 and the rebar information 86.

[0046] When the control unit 50 generates the third processing plan information 93, it activates the processing processing unit 20 and the supply unit 40 based on this information to start processing the reinforcing bars in accordance with the third processing plan information 93.

[0047] In the above description, the control unit 50 generates the second processing plan information 92 using either the first processing information 83 or the first processing information 84, excluding the one that has already been selected from the first processing information 81, first processing information 82, first processing information 83, and first processing information 84. However, the second processing plan information 92 may also be generated using both of these.

[0048] In this case, the control unit 50 only needs to generate second processing plan information 92 for successively generating workpiece 82A of the remaining number X, workpiece 83A based on the first processing information 83, and workpiece 84A based on the first processing information 84, based on the remaining number X, information other than the number of processing units included in the first processing information 82, the first processing information 83, the first processing information 84, the second processing information 85, and the rebar information 86. In this case, the generation of third processing plan information 93 is unnecessary.

[0049] When M=3, the control unit 50 generates first processing plan information 91 for successively generating three types of processed objects, processed object 81A, processed object 82A, and processed object 83A, based on the first processing information 81, first processing information 82, first processing information 83, second processing information 85, and rebar information 86.

[0050] Let's assume that, as a result of processing based on this first processing plan information 91, the generation of some of the three types of processed objects (for example, processed object 81A) is completed, while the generation of the other parts of the three types of processed objects (for example, processed objects 82A and processed objects 83A) is not yet complete. In this case, the control unit 50 should generate second processing plan information 92 for the continuous generation of the remaining number of processed objects 82A and processed objects 83A, and a predetermined number of processed objects 84A, based on the remaining number of processed objects 82A, the remaining number of processed objects 83A, the first processing information 82, the first processing information 83, the first processing information 84, the second processing information 85, and the rebar information 86.

[0051] Furthermore, we assume a case where, as a result of processing based on this first processing plan information 91, the generation of some of these three types of processed objects (for example, processed object 81A, processed object 82A) is completed, while the generation of the other parts of these three types of processed objects (for example, processed object 83A) is not yet completed. In this case, the control unit 50 should generate second processing plan information 92 for the continuous generation of the remaining processed objects 83A and a predetermined number of processed objects 84A, based on the remaining number of processed objects 83A, the first processing information 83, the first processing information 84, the second processing information 85, and the rebar information 86.

[0052] As described above, the rebar processing machine 100 generates first processing plan information 91 based on the first processing information 81, first processing information 82, first processing information 83, and a portion of the first processing information 84, and processing is started based on this first processing plan information 91. Therefore, the load required to generate the first processing plan information 91 can be reduced, and the time until processing can be started can be shortened. Furthermore, after processing based on the first processing plan information 91 has started, the processing plan information is updated according to the progress of processing. In this way, the processing plan can be appropriately updated according to the progress, so the time until the production of all processed parts can be shortened. In addition, by updating the processing plan according to the progress, it is also possible to reduce the amount of waste material that is discarded.

[0053] Furthermore, since the rebar processing machine 100 generates processing plan information based on the second processing information 85, the processing plan can be determined flexibly. For example, if a large amount of leftover material shorter than the length specified in the second processing information 85 (leftover material to be discarded) is generated, the order in which the processed products are produced can be changed to reduce such leftover material so that leftover material of the required length remains. This makes it possible to achieve both effective utilization of leftover material and improved efficiency in producing processed products. [Explanation of Symbols]
