The Although not shown, the guide groove 22 is provided with a magnetic strip extending in the front-rear direction. This magnetic strip is detected by a sensor (not shown) of the measuring instrument 3 and the moving distance of the measuring instrument 3 is measured. The A drop-off prevention member 21 for preventing the measuring instrument 3 from moving forward from the front end of the rail 2 is attached to the upper surface of the front end portion of the rail 2.

  As shown in FIG. 2, the measuring instrument 3 is supported by a main body 30 that is guided by the rail 2 and can move on the rail 2, and a mounting arm 36 that is attached to the upper surface of the main body 30. A display unit 35 for displaying a moving distance of the unit 30 on the rail 2, a moving grip 33 provided on the upper surface of the main unit 30 for manually moving the main unit 30 on the rail 2, and a left side surface of the main unit 30. And a clamp lever 34 that locks the movement of the main body 30. The moving distance of the main body 30 displayed on the display unit 35 is measured by detecting the magnetic strip with a sensor provided in the main body 30.

  The abutment device 4 includes a connecting body 40 disposed so as to be swingable in a vertical plane via a support shaft 42 attached in the front-rear direction on the right side surface of the main body 30, a main rod portion 51, and a sub rod portion 44 (whichever Through-holes for guiding in the front-rear direction and a guide support plate 43 attached to the rear side surface of the connection body 40, and passing through the guide support plate 43 and the connection body 40 in the front-rear direction. The main rod portion (which is an example of a contact guide body) 51 disposed on the front end and a spring whose front end is attached to the outer periphery of the main rod through hole of the guide support plate 43 and urges the main rod portion 51 in the rearward direction. 52 (which is an example of an urging means), and the front end portion is passed through the auxiliary rod through hole of the guide support plate 43, and the rear end face is attached to a contact block (described later) 45 together with the main rod portion 51. Contact block 45 A sub-rod portion 44 that is movable in the front-rear direction, and a contact block (an example of a contact member) whose front surface is attached to the rear end surfaces of the main rod portion 51 and the sub-rod portion 44 so that the rear surface can contact the workpiece. 45).

  Here, the main rod portion 51 will be described in detail. The main rod portion 51 includes a stopper ring 53 for receiving a backward biasing force by the spring 52 and a drop prevention ring 55 for preventing the main rod portion 51 from dropping from the connecting body 40 by the biasing force by the spring 52.

The stopper ring 53 has a structure in which the fixing position of the main rod portion 51 in the front-rear direction can be freely adjusted so that the urging force by the spring 52 can be adjusted. For example, by adopting a structure in which the stopper ring 53 is fixed to the main rod portion 51 with a screw 54, the fixing position can be freely adjusted in the front-rear direction.

  Next, the relationship between the main body 30 of the measuring device 3 and the connection body 40 of the contact device 4 will be described with reference to FIG. FIG. 3 is a partially cutaway sectional view of the central section in the front-rear direction of the main body 30 and the connection body 40 as viewed from the rear to the front. As shown in FIG. 3, the connection body 40 is formed with a projection 41 toward the main body 30, and the main body 30 is formed with a notch 31 on the surface facing the connection body 40. The connection body 40 is arranged so that 41 enters the notch 31. Further, a restriction bolt 32 is screwed into the main body 30 from above, and a lower portion of the restriction bolt 32 is protruded from the upper end surface of the notch 31, and the protrusion 41 is restricted by the lower end surface of the restriction bolt 32. Thus, the rotation of the connection body 40 in the direction in which the guide support plate 43 moves downward is restricted. On the other hand, since the notch 31 is formed in such a size that the lower end surface thereof does not come into contact with the protrusion 41, the connecting body 40 can be rotated in the direction in which the guide support plate 43 moves upward.

  On the other hand, as shown in FIG. 1, a support conveyor 10 for placing a workpiece is disposed in the frame portion 11 in the front-rear direction in which steel materials are assembled in a frame shape, and supports the workpiece while being disposed in the frame portion 11. And a plurality of rollers 12 that can be conveyed in the front-rear direction, and a telescopic leg portion 13 that supports the gantry 11. The length measuring device 1 is fixed onto the support conveyor 10 by a holding metal fitting 14 that connects the gantry 11 of the support conveyor 10 and the rail 2.

  The cutting machine 15 includes a cutting table 16 on which the workpiece is placed, a cutter unit 18 having a rotary cutter 19 for cutting the workpiece placed on the cutting table 16, and the cutter unit 18 above the cutting table 16. And a lever portion 17 that can hold and lower the cutter portion 18.

Hereinafter, workpiece length measurement and workpiece cutting using the length measuring device 1 will be described.
First, in order to obtain a state as shown in FIG. 1, the length measuring device 1 is arranged on the support conveyor 10 by a crane or the like and fixed by the holding metal fitting 14. Then, the length measuring device 1 is arranged in front of the cutting machine 15, and the expansion and contraction of the leg column 13 of the support conveyor 10 is adjusted so that the upper surface of the cutting table 16 and the upper end of the roller 12 of the support conveyor 10 are flush with each other. Thereafter, the cutting machine 15 and the length measuring device 1 are fixed.

  Next, as shown in FIG. 4A, the cutter unit 18 is lowered by the lever unit 17 of the cutting machine 15, and the measuring instrument 3 is moved backward by manually holding the moving grip 33 of the measuring instrument 3. Then, the rear surface of the contact block 45 is brought into light contact with the front surface of the rotary cutter 19 (so that the spring 52 does not contract). In order to use this position as a reference, a reset button (not shown) provided on the display unit 35 is pressed to reset measurement by the sensor. As a result, “0” is displayed as the movement distance on the display unit 35.

  Thereafter, the measuring instrument 3 is moved in the forward direction while confirming the moving distance displayed on the display unit 35. If the displayed moving distance matches the required workpiece length, the movement of the measuring instrument 3 is stopped, the movement of the measuring instrument 3 is locked by the clamp lever 34, and the measuring instrument 3 is fixed on the rail 2. To do.

  Then, as shown in FIG. 4B, the work W is placed on the upper surfaces of the cutting table 16 and the roller 12, and the work W is moved forward until the work W lightly contacts the rear surface of the contact block 45. Transport. When the work W pushes the contact block 45 and the spring 52 contracts due to this conveyance, the work W is gradually returned backward until the spring 52 does not contract.

The work W is measured by the above operation. That is, the length from the front end of the workpiece W to the scheduled cutting position matches the required length of the workpiece W.
Thereafter, as shown in FIG. 4C, the cutter portion 18 is lowered by the lever portion 17, and the workpiece W is cut by the rotary cutter 19. At the time of this cutting, the workpiece W is tilted from the cutting location, and the front end surface of the workpiece W pushes up the contact block 45 from the rear direction, but the contact block 45 moves forward and releases the force received from the workpiece W. Further, the contact block 45 moved in the forward direction pushes back the workpiece W in the backward direction by the biasing force of the spring 52.

  On the other hand, when the length measuring device 1 is not used, as shown in FIG. 3, the connecting body 40 is rotated in the direction in which the guide support plate 43 moves upward, and the abutment device 4 is moved toward the measuring device 3 side. Thus, when other work is performed on the support conveyor 10, the abutment device 4 does not interfere.

  Thus, even if the contact device 4 is fixed on the rail 2 together with the measuring device 3 by the clamp lever 34, the contact block 45 can move forward, so that the force received from the workpiece W being cut is released. Thus, damage to the length measuring device 1 can be prevented. Further, when the workpiece W is inclined, the contact block 45 pushes the workpiece W backward by the urging force of the spring 52, so that the cut workpiece W can be prevented from jumping and the inclination of the workpiece W during cutting can be suppressed. Thus, the rotating cutter 19 can be prevented from being damaged or worn. Furthermore, it is possible to prevent the length measuring device 1 from interfering with other work by rotating the connecting body 40 and bringing the abutment device 4 toward the measuring device 3 side.

By the way, although the said Example demonstrated the apparatus which integrated the length measuring apparatus, the support conveyor, and the cutting machine, you may use only with a length measuring apparatus.
Moreover, although the said Example demonstrated the length measuring apparatus for workpiece | work, it is not limited to the object for workpiece | work.

  Furthermore, the main material of the length measuring device in the above embodiment is suitable because it is lightweight and has corrosion resistance, considering the stability and corrosion resistance of the support conveyor to which the length measuring device is fixed, but is not limited thereto. However, other materials may be used.
