  Hereinafter, a frame material printing apparatus 10 according to a first embodiment of the present invention will be described with reference to FIGS. The frame material printing apparatus 10 is a transfer mechanism on which an elongate frame material 12 that is a workpiece to be printed such as drawing or printing is placed, and the frame material 12 can be transferred in the X-axis direction, which is the longitudinal direction. A roller conveyor 14 is provided. Furthermore, a printer unit 16 provided with a printer head 17 capable of moving on the roller conveyor 14 in the Y-axis direction and the Z-axis direction perpendicular to the X-axis, and a control unit 18 for controlling the operation of the printer unit 16 are provided. .

  The frame material 12 is an aluminum extruded profile, and as shown in FIG. 2, has a total length L and a cross-section having a square shape with a length D on one side. A hollow hole 20 is provided in the central portion and four corners of the cross section, and a T-groove 22 is provided from the four sides toward the central portion of the cross section. The opening 22a of the T-groove 22 has a width of the dimension α, and the groove 22b that enters the inside from the opening 22a has a width of the dimension β that is wider than the dimension α.

  The roller conveyor 14 includes four support legs 14b that support the conveyor body 14a from below, a number of rollers 14c that are horizontally mounted on the conveyor body 14a and that support the frame material 12 from below, and at least described below. A driving device (not shown) for controlling the rotation of the roller 14c below the printer head 17 is provided. In the roller conveyor 14, the length of the transfer surface formed by the rollers 14 c in the transfer direction is set to about 2.5 times the total length L of the frame material 12. A positioning guide (not shown) may be provided on the roller conveyor 14 in order to define the position where the frame material 12 is placed on the roller conveyor 14. Further, the roller conveyor 14 may be replaced with a belt conveyor or the like having a similar function, and a feed mechanism for the frame material 12 may be provided on the printer unit 16 side described later using the roller conveyor as a free roller.

  The printer unit 16 has a support column 24 that can be moved up and down in the Z-axis direction by a lifting mechanism (not shown), and is provided substantially horizontally from the upper end of the support column 24, and has a length approximately equal to the width of the roller conveyor 14. A head mounting portion 26 is provided. Inside the head mounting portion 26, an ink tank (not shown) filled with printing ink, a Y-axis slide rail, and a head driving mechanism are provided. The printer head 17 is disposed downward from the head mounting portion 26 and is movably mounted on the Y-axis slide rail by a head driving mechanism. The printer head 17 receives ink supplied from the ink tank and performs predetermined printing on the frame material 12. It can be carried out.

  As the ink, for example, a quick-drying thermosetting ink or an ultraviolet curable ink is selected by providing an ultraviolet lamp. Thereby, work efficiency is good and the handling of the frame material 12 after drawing or printing is also easy. Furthermore, the ink can be wiped off after being cured by applying an alcohol or a solvent.

  The printer unit 16 is disposed substantially above the center of the roller conveyor 14. Accordingly, when the frame material 12 moves from end to end on the roller conveyor 14, the printer head 17 can perform printing on the entire upper surface of the frame material 12.

  The control unit 18 is configured by a computer or the like provided with a terminal that can be operated by the worker, and controls the operation of the printer unit 16 based on a program registered in advance or an individual command input by the worker. The control unit 18 may also perform operation control of the roller conveyor 14 at the same time.

  The design printed by the control unit 18 on the surface of the frame material 12 is such that when a plurality of parts produced by cutting the frame material 12 are assembled to form a structure, specific parts are placed in contact with each other. For example, a partner identification mark for identifying a counterpart part, a bolt identification mark written in the vicinity of the mounting position of the fixing bolt.

  Specific examples of symbols are shown in FIGS. Here, two relatively long vertical parts 28 and 30 and four relatively short horizontal parts 32, 34, 36, and 38 are cut out from the frame material 12 having an overall length L, and these are assembled in a lattice shape to form a structure. The case where 40 is formed will be described. The structural body 40 is arranged in a lattice shape as shown in the plan view of FIG. 5, and in the assembled state, the left end surface of the horizontal parts 32, 34, 36, 38 abuts on a predetermined position on the right side surface of the vertical part 28, The right end surface comes into contact with a predetermined portion on the left side surface of the vertical part 30.

  For example, in the case of the vertical part 28, as shown in FIG. 3A, “1A”, “2A”, “3A” of the opponent specific marks indicating the opponent's horizontal parts 32, 34, 36, 38 on the upper surface of the vertical part 28. The character “4A” is printed. In addition, this partner identification mark can also be used as a position identification mark indicating the contact position because it also serves as a mark of the position where the other party's lateral part contacts depending on the printing position. A plurality of short horizontal lines are drawn as easy position specifying marks.

  On the right side surface of the vertical part 28, as shown in FIG. 3B, the horizontal part which is a position specifying mark is in an area (contact area) where the end surfaces of the other side parts 32, 34, 36, 38 abut. A cross-sectional view is drawn. With such a design, it is easy to visually judge even when the cross-sectional shape of the horizontal part is asymmetric and must be attached in consideration of directionality. Further, on the side of the position specifying mark, a bracket position mark surrounding a region where a mounting bracket 42 to be described later is mounted is drawn, and further, a bolt used to fasten and fix the other side part via the mounting bracket 42. The character of the bolt specific mark “M6” indicating 44 types is printed.

  In the case of the horizontal part 34, as shown in FIG. 4A, characters “2A” and “2B” are printed on the upper surface of the horizontal part 34, which are counterpart identification marks indicating the counterpart vertical parts 28 and 30. . The counterpart identification mark also serves as a mark for identifying the contact position of the counterpart vertical parts 28 and 30 based on the printing position.

  Further, as shown in FIGS. 4B and 4C, a bracket position mark is drawn on the front and back of the vertical part 28 so as to surround a region where a mounting bracket 42 to be described later is attached. The bolt specific mark “M6” indicating the type of the bolt 44 used for tightening and fixing via the mounting bracket 42 is printed.

  Similarly, the position specifying mark, the other party specifying mark, the bolt specifying mark, and the bracket position mark are also printed at predetermined positions on the other vertical parts 30 and horizontal parts 32, 36, and 38.

  By using the frame material printing apparatus 10 configured as described above, a predetermined design can be easily printed on the frame material 12 having a long length. As a result, the structure 40 can be easily assembled.

  Furthermore, the following effects are obtained by applying the predetermined printing as described above to the frame member 12. First, six parts on which predetermined marks are printed are arranged in a grid pattern as shown in FIG. At this time, since each part should just arrange | position so that a mutual position specific mark and the other party specific mark may appear correspondingly, it can carry out easily and correctly.

  Also, each part is mounted and fixed in the shape of an L-shaped mounting bracket 42 having through holes formed on two surfaces, a bolt 44 having a specification designated by a bolt specific mark, and the width of the opening 22a of the T groove 22 of each part. The method shown in FIG. 6 is performed using a nut 46 and a nut holder 48 having an outer shape larger than the dimension α and smaller than the width dimension β of the groove 22b. At this time, the bolt 44 to be used can be accurately recognized by the bolt specific mark, and the mounting position of the mounting bracket 42 can be recognized at a glance and can be noticed at a glance by the bracket position mark. .

  In addition, the position identification mark, counterpart identification mark, bolt identification mark, and bracket position mark exposed on the surface can be wiped off by applying alcohol or solvent after the assembly of the structure 40 is completed. The body 40 can be finished nicely.

  Next, a frame material printing apparatus 50 according to a second embodiment of the present invention will be described with reference to FIG. Here, the same components as those of the frame material printing apparatus 10 are denoted by the same reference numerals, and description thereof is omitted. The frame material printing apparatus 50 includes a printer unit 52 that self-travels on the frame material 12 as a work and performs drawing or printing on the surface of the frame material 12. Therefore, it does not include a frame material 12 transfer mechanism such as the roller conveyor 14 of the frame material printing apparatus 10.

  The printer unit 52 includes a substantially rectangular main body 54, a printer head 17 (not shown) provided downward in the center of the lower surface of the main body 54, and a pair of left and right travel guides that are engaged with the outer sides of the left and right side surfaces of the frame member 12. A part 56 and a self-propelled mechanism (not shown) that moves the main body 54 on the frame member 12 in the longitudinal direction are provided. Other configurations are the same as those of the frame material printing apparatus 10.

  Due to such a configuration, the printer unit 52 can freely move to an arbitrary position and perform drawing or printing accurately. Further, since a transfer mechanism for the frame material 12 is not required, a large space is not required for installation of the apparatus itself. Further, the function and effect of the control unit 18 is the same as that of the frame material printing apparatus 10.

  The traveling guide 56 utilizes the characteristics of the outer shape of the frame material, which is a metal continuous body having a predetermined cross-sectional shape, and is, for example, a T-groove that is a rail-shaped groove formed on the surface of the frame material 12. It is good also as a form engaged with 22.
