[0001] The present invention relates to a precut processing device. [Background technology]

[0002] Conventionally, a construction method using precut processing has been adopted in which processed materials (products) such as beams, pillars, and finials used in building structures such as houses are manufactured by wood processing equipment (precut processing equipment) in a precut factory, making it possible to omit cutting processing at the construction site and efficiently manufacturing building structures. In the precut factory, processed materials are manufactured by cutting lumber (input materials) as materials using a processing machine. The input materials and processed materials are transported appropriately to required locations, and finally, after being stacked in multiple layers, they are packaged with cable ties or the like. The packaged processed materials are loaded onto truck beds or the like and shipped to the construction site (see Patent Document 1). [Prior art documents] [Patent documents]

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic diagram for explaining an example of a precut processing device 10 according to the present invention, showing a state in which the precut processing device 10 is viewed in plan. In FIG. 1, electrical wiring connecting the processing machine 11, the moving device 12, the conveying device 13, the member placement device 14, the inspection device 15, and the control device 16 is omitted. In addition, the direction of the outline arrow indicates the direction in which the input material and the processed material advance, and the line arrow indicates the operation direction of the conveying device 13 (contact portion 13a) and the member placement device 14 (support portion 14a). In addition, the arrangement positions of the processing machine 11, which processes the input material and the processed material, the inspection device 15, and the control device 16 are indicated by thick solid lines, the operable range MR of the contact portion 13a of the conveying device 13 is indicated by dotted lines, and some components such as the frame and operation mechanism of the conveying device 13 are omitted from the illustration, and some of the input material and the processed material are illustrated for reference.

[0015] The precut processing device 10 processes materials (products) such as pillars, cross members, beams, and feather-shaped materials used in houses. The precut processing device 10 processes rod-shaped members having a longitudinal direction as input materials, and is characterized in that both the input materials and the processed materials (hereinafter also referred to as "materials to be transported") can be transported by a common transport device 13. As shown in FIG. 1, the input materials are placed so that their longitudinal directions face the same direction (X direction) at positions (input material placement section 14b, input section 12a) before and after the transport of the input materials by the transport device 13, and positions (discharge section 12b, processed material placement section 14c) before and after the transport of the processed materials (products). The input material placement section 14b, the input section 12a, the discharge section 12b, and the processed material placement section 14c are arranged in a line along the Y direction intersecting the X direction. Below, the basic configuration of the precut processing device 10 will be described, and then the characteristic configuration will be described with reference to FIG. 2.

[0016] The precut processing apparatus 10 comprises a processing machine 11, a moving device 12, a transport device 13, a member placement device 14, an inspection device 15, and a control device 16. Note that the configuration of the precut processing apparatus 10 is one example, and some of the devices such as the inspection device 15 do not necessarily need to be provided, and the precut processing apparatus 10 can also be configured by combining devices that add other functions, such as a printing device for printing identification information for each processed material and a dust collection device for collecting dust.

[0017] The processing machine 11 is a device for cutting input materials to manufacture processed materials as products, and can be configured with processing machines capable of various types of processing, or can be configured with dedicated machines corresponding to different types of processing, such as cutting processing, side processing, and end processing. FIG. 1 illustrates a case where the precut processing device 10 is equipped with two processing machines 11, but the number of processing machines 11 is not limited to two, and one, or three or more may be provided. In addition, a configuration is illustrated in which the moving path along which the input materials or processed materials are processed by the processing machine 11 passes through one (one) path, but a branch portion is present in the path, and the input materials or processed materials may proceed in parallel, for example, to include a path portion that does not pass through.

[0018] The moving device 12 is a device that allows the moving of materials to be moved along a predetermined moving path, such as materials to be moved that have been processed by the processing machine 11, or materials to be input before being processed by the processing machine 11. The moving device 12 can utilize various conventional mechanisms, and can be configured using a rotating roller or a rotating belt that supports the underside of the material to be moved, or a device (traverser) that clamps both sides of the material to be moved and moves it along the moving path.

[0019] The conveying device 13 is a device that allows the input material or processed material (material to be conveyed) to be conveyed to come into contact with the contact part 13a and move upward, and then move linearly to the horizontal side. The conveying device 13 can use various conventional mechanisms, and can be configured, for example, as a gantry-type crane that can move the contact part 13a linearly in the Y direction along a rail that continues in the Y direction. The contact part 13a is also configured to be movable in the X direction, which is the same as the longitudinal direction of the material to be conveyed. In this way, when input materials of different lengths are used, the contact part 13a can be moved to a position close to the center of gravity of each input material, and each input material can be conveyed in a stable state, and the processed materials can be stacked in a package shape including a portion where multiple pieces are arranged in the longitudinal direction. The contact part 13a can be configured as a suction pad type device that generates negative pressure on the contact surface to adsorb the material to be conveyed and move it, or as a conveying hand type device that can clamp and hold both sides of the material to be conveyed in the width direction from the horizontal side and lift it up.

[0020] The inspection device 15 is a part of the moving path along which the workpiece can be moved by the moving device 12, and is provided in a section along which the workpiece processed by the processing machine 11 is moved by the moving device 12. The inspection device 15 is configured to be able to inspect the details of processing by the processing machine 11. Specifically, the inspection device 15 is configured by a device that can acquire inspection data by irradiating both ends of the workpiece along the longitudinal direction with a laser to measure dimensions or by taking images. The inspection data acquired from the inspection device 15 is input to the control device 16, which compares the shape data and dimensional data for precut processing with the actual dimensions and shape data of the workpiece to inspect the details of processing, such as the presence or absence of processing and the accuracy of processing. The inspection of the details of processing can also be performed by comparing the teacher data and the image using artificial intelligence (AI). Note that the inspection device 15 and the control device 16 may acquire other data, such as the length of the workpiece, the warp in the longitudinal direction, and the cross-sectional size of the workpiece, in addition to the shape of both ends of the workpiece, and inspect the details of processing other than both ends of the workpiece.

[0021] The control device 16 is a device that controls the operation of the processing machine 11, the moving device 12, the conveying device 13, the member placing device 14, etc., and conveys the input material and the processed material along the movement path, thereby performing precut processing on the input material. The control device 16 is composed of devices including a calculation processing device that performs various calculations, a storage device that stores information for controlling programs and drive mechanisms and information necessary for executing programs, an input / output device that transfers data with the processing machine 11 and an external input device (such as a memory stick), an operation device such as a mouse or keyboard that allows the worker to input the processing order of the processed materials, etc., and a display device that displays progress information such as the processing order of the processed materials and the processing results, etc., and can be composed of a personal computer, for example.

[0022] Next, the characteristic configuration of the precut processing device 10 will be described with reference to Fig. 2. Fig. 2 is a side view of the input / output area R2 of the precut processing device 10 as seen from the direction of the arrow S in Fig. 1. For ease of understanding, Fig. 2 also illustrates the input material and processed material, and omits the illustration of some devices such as the processing machine 11.

[0023] As shown in Fig. 1, the precut processing device 10 is configured such that a processing area R1, an input / output area R2, and a working area R3 are positioned side by side in the horizontal direction (X direction) in a plan view. The processing area R1 is an area for processing input materials to produce processed materials, and is configured to include a processing machine 11 and a part of a moving device 12. The input / output area R2 is an area for inputting input materials and stacking processed materials. The working area R3 is an area for carrying in input materials and carrying out unloading work for unloading processed materials stacked in a predetermined packing form.

[0024] The input / discharge area R2 is set in accordance with the range (operable range MR) in which the contact portion 13a of the conveying device 13 can transport the material to be transported, and as shown in Fig. 2, is composed of the input material placing portion 14b, the processed material placing portion 14c, the input portion 12a, the discharge portion 12b, and the temporary placement portion 17. The input material placing portion 14b is a portion on which the input material can be placed, and the processed material placing portion 14c is a portion on which the processed material can be placed. The input material placing portion 14b and the processed material placing portion 14c are composed of the member placing device 14 on which the input material and the processed material can be placed, and although a case where they are composed of the same device is illustrated, they may be composed of different devices. In addition, the arrangement of the input material placement section 14b, the processed material placement section 14c, the input section 12a, the discharge section 12b, and the temporary placement section 17 is not limited to the order of arrangement shown in FIG. 1, and they may be arranged in other orders. Also, the precut processing device 10 may be configured by providing another member placement device 14 (for example, the processed material placement section 14c) at a position outside the operable range MR of one conveying device 13.

[0025] The input section 12a and the discharge section 12b are formed as part of the moving device 12. The input section 12a corresponds to the most upstream part of the movement path along which the moving device 12 moves the input material to the processing machine 11, and is disposed at a position where the input material can be linearly transported in the Y direction from the input material placement section 14b by the contact section 13a of the transport device 13. The discharge section 12b corresponds to the most downstream part of the movement path along which the processed material (product) processed by the processing machine 11 is moved, and is disposed at a position where the processed material can be linearly transported in the Y direction from the discharge section 12b to the processed material placement section 14c by the contact section 13a of the transport device 13.

[0026] As shown in Fig. 1, the member placement device 14 preferably includes a moving mechanism that can move the support part 14a that supports the lower side of the input material or the processed material between a preparation position (first position shown by a solid line in Fig. 1) where the material to be transported is transported by the transport device and a working position (second position shown by a two-dot chain line in Fig. 1) that is set on one side (-X direction side) along the X direction with respect to the preparation position. The support part 14a may be configured in a flat plate shape, or may be configured by installing a columnar support material capable of supporting the lower side of the input material at multiple locations spaced apart in the X direction so as to face the Y direction intersecting the longitudinal direction of the input material. The moving mechanism that moves the support part 14a can be configured by combining a slide mechanism such as a rail with a power source such as a motor, or may be configured by using a moving mechanism that can be moved by the human power of an operator.

[0027] The worker moves the support part 14a of the member placement device 14 to the working position, and transports a packing material in which a large number of input materials are bundled together using a transport machine such as a lift, and places it on the top of the support part 14a. After that, the worker moves the support part 14a to the preparation position using the movement mechanism, so that the input materials are prepared at a position where the transport device 13 can transport the input materials. In addition, by providing the member placement device 14 with a movement mechanism, the movement distance over which the transport device 13 moves the input materials and processed materials can be set short. For example, the processed material placement part 14c and the discharge part 12b can be arranged side by side, and the input material placement part 14b, the temporary placement part 17, and the input part 12a can also be arranged side by side, so that the input and discharge area R2 can be set within a small space.

[0028] Furthermore, the work area R3 in which the work position is set is provided on one side along the X direction (-X direction side) as viewed from the input / output area R2 in which the member mounting device 14 is provided, and the processing area R1 (processing machine 11) is provided on the other side (+X direction side) opposite the work area R3 with respect to the input / output area R2 (member mounting device 14). This allows the space around the work area R3 to be set large, making it easy to carry out tasks such as bringing in input materials and unloading processed materials.

[0029] The moving mechanism of the member placement device 14 may be configured to be controlled by the control device 16, or the support part 14a may be operable by direct operation of the control device 16. In addition, it is preferable that the display part and the operation part (e.g., the touch panel 18) for operating the contact part 13a of the transport device 13 and the moving mechanism of the member placement device 14 (support part 14a) are provided in the working area R3 or are installed facing the working area R3. For example, a display corresponding to the case where the input material placement part 14b is empty due to the input material being exhausted, or a display corresponding to the completion of loading of the processed material (product) may be displayed on the display part of the working area R3 so that the worker can check it. In addition, it is preferable that the contact part 13a and the support part 14a can be moved by operating the operation part of the working area R3 without the worker moving to the installation position of the control device 16. Furthermore, the support portion 14a does not necessarily need to be configured to be movable, and may be configured as a fixed platform without a moving mechanism, and the input material may be slid and transported from the working area R3 side to the support portion 14a.

[0030] The member placement device 14 is preferably configured to be capable of placing both input materials and processed materials, and each member placement device 14 is preferably configured to be usable as either the input material placement section 14b or the processed material placement section 14c. For example, when the input materials placed on the input material placement section 14b are empty, a selection screen that allows the operator to select whether to use the member placement device 14 as the input material placement section 14b or the processed material placement section 14c may be displayed on the display section, and the object to be placed may be set to either the input material or the processed material depending on the selection result. In addition, it is not necessarily required for the operator to set the object to be placed, and the control device 16 may be configured to include a control for selecting and determining the object to be placed depending on the progress of processing.

[0031] It is preferable that the member placing devices 14 are provided at two or more locations in one precut processing apparatus 10, and one can be used as the input material placing section 14b and the other as the processed material placing section 14c. Three or more member placing devices 14 (three or more locations) may be provided, two or more of them may be arranged next to each other in the Y direction, or a member placing device 14 (for example, the input material placing section 14b) may be provided outside the input section 12a (upper side in FIG. 1), and a part of the member placing device 14 may be used as the temporary placement section 17.

[0032] Also, the input material placement section 14b may be set at two or more locations to allow input of the input material, and rod-shaped members (materials) with different cross-sectional sizes may be placed on each of the input material placement sections 14b to process the input material. This allows the input materials with different cross-sectional sizes to be input to the moving device 12 in a mixed order, and processed materials (products) with different cross-sectional sizes can be efficiently manufactured. In this case, whether the member placement device 14 is the input material placement section 14b or the processed material placement section 14c, and information on the cross-sectional size may be input (set) to the control device 16, and the control device 16 may control the operation of the conveying device 13 so that it functions as the set placement section. The input of information on the material and the setting of the placement section may be manually input by an operator, or material information such as a barcode on which information such as the cross-sectional size and length is printed may be added to a packaging section in which a large number of input materials are packed, and the material information may be input to the control device 16 by an imaging device such as a camera.

[0033] The temporary placement section 17 is a section where the input materials can be temporarily placed before being inputted into the input section 12a, and is illustrated as being located on one side along the Y direction (+Y direction side) of the input material placement section 14b. The control device 16 controls the operation of the conveying device 13 to convey the input materials before being inputted into the input section 12a from the input material placement section 14b to the temporary placement section 17, and temporarily place them there. For example, in a situation where the number of input materials remaining is low, by conveying the remaining input materials from the input material placement section 14b to the temporary placement section 17, the input materials placed on the input material placement section 14b can be eliminated early, and the carrying-in work for packaging the next input materials and placing them on the input material placement section 14b can be started at an early stage.

[0034] Since the temporary placement section 17 is provided within the movable range of the conveying device 13, it can also convey and temporarily place processed materials before they are conveyed from the discharge section 12b by the conveying device 13 to the processed material placement section 14c. This makes it possible to change the order in which the processed materials are conveyed to the processed material placement section 14c so that the processed materials are packed in a predetermined manner, even if the order in which the processed materials are stacked in a line in the processed material placement section 14c differs from the order in which the processed materials are completed. In addition, since the temporary placement section 17 is configured to be able to temporarily place both the processed materials and the input materials, it is possible to temporarily place the processed materials and the input materials more efficiently within a limited area than when a temporary placement space for the processed materials and a temporary placement space for the input materials are set separately.

[0035] The temporary placement section 17 may be provided in multiple locations instead of one. It is also preferable to provide the temporary placement section 17 between the input material placement section 14b and the processed material placement section 14c as the temporary placement section 17. In this case, both the input material and the processed material can be easily transported to the temporary placement section 17 over a short distance.

[0036] According to the precut processing device 10 described above, the contact portion 13a of the conveying device 13 is configured to be linearly movable along the Y direction, and both the input material and the processed material can be conveyed from the input material placement portion 14b to the input portion 12a by the linear movement of the contact portion 13a along the Y direction. Therefore, the installation cost of the conveying device 13 can be reduced compared to providing a separate conveying device 13 for each of the input material and the processed material.

[0037] In addition, the input material placement section 14b, the processed material placement section 14c, the input section 12a, and the discharge section 12b are each configured to be able to place the input material or the processed material with the same direction (X direction) as the longitudinal direction. The processed material placement section 14c, the input section 12a, and the discharge section 12b are each located on one side (+Y direction side) or the other side (-Y direction side) along the Y direction with respect to the input material placement section 14b, and are arranged so that they are positioned side by side. Therefore, the input material placement section 14b, the processed material placement section 14c, the input section 12a, and the discharge section 12b can be arranged together as the input and discharge area R2, and the input material carry-in space and the processed material carry-out space can be set so that they are gathered in a limited space. In addition, since the work areas for bringing in input materials and removing processed materials can be located close to each other, it is easier to share the work space for each task, making it easier to secure a large work space.

[0038] The present invention is not limited to the above-described embodiment, and may be modified as described below. In this case, each of the configurations described below may be applied to the above-described embodiment, or multiple configurations described below may be combined and applied to the above-described embodiment.

[0039] In the above embodiment, the case where only one contact part 13a is provided on the conveying device 13 is illustrated, but two or more contact parts 13a may be provided to enable simultaneous conveyance of two or more conveying target materials. For example, a gantry-type crane that can move the contact part 13a in the Y direction along a rail may be provided with two or more suspended contact parts 13a and configured to be movable by a common rail, one of which is used mainly for conveying input materials and the other is used mainly for conveying processed materials, and when the materials to be conveyed that need to be conveyed are biased toward either the input materials or the processed materials, the multiple contact parts 13a may be used to efficiently convey the materials to be conveyed.
