Description

  The present invention is a technique related to a unified management system for wood precut work that is managed by making paperless precut work.

  In the conventional construction method of wooden construction, each use and installation location in a factory that pre-cuts various types of building wood including structural materials such as beams and foundations and pillar materials (referred to as “pre-cut factory” in this specification). It is common to pre-cut (referred to as “pre-cut wood” in the present specification) as an actual product corresponding to the above and then carry it to a construction site for assembly.

  In a precut factory, usually, woodcutting work, processing work, and shipping inspection work (in this specification, collectively referred to as “wood precut work”), precut wood is used as an actual product at the construction site. It will be carried out.

  Here, the lumbering work refers to a work for preparing timber as a material necessary for each property in order to process a structural material for a house. Specifically, the necessary number of necessary materials should be prepared from the inventory shelf based on the wood table (use, tree type, grade, timber width, timber material, and material length described in the document) output by CAD. Done in

  In this case, the conventional method of tree-drawing work is to output a woodcut table as a form of, for example, about 10 sheets of A4 paper per building from precut input data at a management office in a precut factory, and rely on this woodcut table. The unloader performed the lumbering work.

  In addition, the processing work refers to the processing that is input in CAD by putting the material prepared in advance through the above-mentioned lumbering work into a processing machine prepared for horizontal material processing and column material processing. This refers to the business of manufacturing processed products from input materials according to data.

  In this case, the conventional methods of processing work are as follows. First, the process instruction, processing instruction, inking instruction, standard processing time instruction, and special instruction instruction for each property at the management office of the precut factory (each factory Output as a paper (for example, a sheet of about 60 sheets of A3 / A4 mixed paper per building), and the processing operator registers the processing data prepared separately in the processing machine. Therefore, it is done by processing.

  The processing work performed in such a precut factory is performed, for example, by performing a precut processing method disclosed in Patent Document 1 below using a predetermined precut facility.

Japanese Patent Laid-Open No. 2003-90078

  Furthermore, the shipping inspection business is whether pre-cut wood as an actual product processed by a processing machine used to process horizontal members or pillars is in accordance with the processing shape output by CAD. This is a job to confirm whether or not.

  In this case, in the conventional method of shipping inspection work, the paper used in the processing instruction work in the processing work is used as the required form, and the precut wood as the actual product is discharged from the processing machine in the order that considers the efficiency of the processing machine. Therefore, when the property processing is started, the shipping inspection operator at the exit of the discharge conveyor visually confirms a unique serial number printed in advance on the precut wood, and information on the member of the serial number from the necessary form This is done by searching for a page, comparing the necessary data described on the page with the actual discharged product, checking the dimensions, and if there is a missing item, marking the required form with a writing instrument and managing it.

  However, in the case of the wood pre-cutting work that has been done in the past, if it is a wood cutting work, the table will be output as a form of about 10 A4 sheets per building, so the property will be changed In such a case, generation management of the tree generation data is necessary, and each time a new generation is generated, there is a trouble that a replacement of about 10 sheets of A4 paper occurs.

  In addition, if there is a deficiency in generation management, the operating efficiency of the processing machine and the efficiency of the tree-making process will be reduced, resulting in a delay in the processing process, and the precut wood will be brought into the construction site. There were inconveniences such as delaying the reputation of the factory and causing additional factory expenses.

  In addition, if the wood pre-cut work is a processing work, for example, it is an instruction on a paper basis with a form of about 60 sheets of A3 / A4 mixed paper per building, so each time it is referenced, it can be returned to the processing machine operator's desk, There was a problem that the flow of work was inadequate, such as carrying it by hand and misplaced it.

  Furthermore, if there is a change in the property, it is necessary to manage the generation of the corresponding forms, and each generation must replace about 60 forms of A3 / A4 mixed paper per building. Inadequate generation management could lead to a decrease in the operating efficiency of the processing machine and a delay in the processing process, delaying the delivery of precut wood to the construction site, degrading the reputation of the factory, and incurring additional factory expenses There were inconveniences such as.

  On the other hand, if the wood pre-cutting work is a shipping inspection work, it is a paper-based instruction in the form, so every time you refer to it, you can return it to the shipping inspection operator's desk or carry it by hand and misplace it. There was a problem that caused deficiencies.

  In addition, when there is a change in the property, there is a problem that the on-site process is confused due to a discrepancy with the discharged precut wood due to the generation management mistake of the corresponding form and processing with the old form.

  In other words, since the shipping inspection work is performed on a paper basis, it is a troublesome task to find the corresponding page and description location of the discharged precut wood from the form of about 60 sheets of A3 / A4 mixed paper per building. There was a problem that forced me to. In addition, since confirmation of missing items is handwritten on the corresponding form, the final confirmation of missing items must be performed on all pages of the processing instruction sheet (average A3 paper 20 sheets / building), which is complicated. In addition, there was a risk of marking another precut wood.

  In other words, in the case of conventional wood pre-cutting operations, all are instructions on a paper basis, so there is a deficiency in generation management, delaying the delivery of products to the construction site, and gaining the reputation of the factory There were inconveniences such as dropping or incurring additional factory expenses.

  In the present invention, in view of the above-mentioned problems seen in the conventional method for wood precutting work, the tree management work, the precut processing work, and the inspection management of the precut wood that is the actual product are centrally managed by the overall management server. The purpose is to provide a unified management system for wood precutting work that can realize paperless cutting of wood precutting work.

  The present invention has been made to achieve the above-described object, and includes a lumbering apparatus for managing lumbering work, a processing work apparatus for managing precutting work for wood to be processed, and discharged precut wood. Ship inspection business equipment for inspecting and managing products, a central management server for managing each of these devices, processing information on the pre-cut wood to the shipping inspection business equipment, and a processing machine to the overall management server The head mounted display, which is composed of a processing machine host computer that sends the feedback information of each, and is mounted by the tree operator, the contents of the tree cutting work sent from the overall management server via the tree cutting work device, The head-mounted display worn by the machining operator is connected to the overall management server via the machining business device. The contents of the current inspection work sent from the central management server can be visually checked on the head mounted display that is installed by the inspection operator. If there is no problem with the wood finishing work that has been completed this time, the wood working device transmits a wood finishing completion to the related department, and the processing business device sends the head mounted display of the processing operator. When the pre-cut timber is discharged from the processing machine, the shipping inspection business device causes the processing machine to perform the current processing based on the instruction display to the processing machine via the processing machine host computer. The inspection standard information on the pre-cut wood for this time sent from The main feature is that it is possible to send an instruction display on the spray to confirm the comparison with the pre-cut wood for this time, and to send the result as the feedback information to the overall management server via the processing machine host computer. And

  According to the present invention, the overall management server is online for each head mounted display mounted by the wood operator, the processing operator, and the shipping inspection operator who are in charge of the wood pre-cut operation. Since necessary information can be indicated and displayed, by sending the necessary information including generation management, which was conventionally done on a paper basis, in a paperless manner, each operator's assigned duties can be accurately and efficiently performed. In addition to being able to carry out, it is possible to centrally manage the necessary information.
