  Furthermore, the lower end side which is one end part of the longitudinal direction of the angle adjustment frame 30 of the elongate rectangular flat plate which protruded upwards from these installation frames 26 is connected with the both ends of the longitudinal direction of a pair of installation frames 26. Yes. These angle adjustment frames 30 are attached in a state where the longitudinal direction is along the vertical direction, and a pair of installation frames are provided with one side surface in the thickness direction of the angle adjustment frame 30 being spaced apart from each other in parallel.

These angle adjustment holes 31 pass through in the thickness direction of the angle adjustment frame 30, and are the central portion in the width direction of the angle adjustment frame 30 and the central portion in the longitudinal direction of the angle adjustment frame 30. Is provided.

  A hinge bolt 32 is inserted into the angle adjustment hole 31 of the angle adjustment frame 30 from the outside of the angle adjustment frame 30. These hinge bolts 32 are screwed and bolted to both ends in the longitudinal direction of an elongated flat plate-like holding frame 33 attached between the angle adjusting frames 30 installed facing each other. Here, these holding frames 33 are welded and fixed to both longitudinal ends of the lower end surface of the conveyor body 4 in a state where the longitudinal direction of the holding frames 33 is along the width direction of the conveyor body 4. Yes. Further, at both ends in the longitudinal direction of these holding frames 33, rectangular flat plate-shaped connecting surface portions 34 parallel to the axial direction and the height direction of the conveyor body 4 are provided. The connecting surface portions 34 are formed with bolt stop holes 35 in which thread grooves into which the hinge bolts 32 can be screwed are formed on the inner peripheral surface.

  Therefore, by loosening the bolting of the holding frame 33 to the bolt fixing hole 35 by the hinge bolt 32, the holding frame 33 is appropriately moved in the vertical direction within the angle adjustment hole 31 of the angle adjustment frame 30 of the gantry 25. The height position of the conveyor body 4 held by these holding frames 33 and the inclination angle θ in the transport direction B of the transport surface 9 of the conveyor body 4 can be adjusted. Accordingly, the angle of the conveyor body 4, that is, the inclination angle θ of the conveyance surface 9 in the conveyance direction B can be adjusted by the hinge bolt 32, the angle adjustment hole 31 of the angle adjustment frame 30, and the bolt stop hole 35 of the holding frame 33. An adjustment mechanism 36 is configured.

  Here, the angle adjusting mechanism 36 is an inclination adjusting mechanism for discharging cutting fluid that adjusts the inclination of the conveying surface 9 of the conveyor body 4, and the conveying surface 9 is directed from the conveying upstream side D to the conveying downstream side C. The cutting fluid E discharged together with the conveyed product A is caused to flow on the conveying surface 9 by its own weight from the conveying downstream side C toward the conveying upstream side D through the drain hole 12. It is discharged from the drain pipe 13 and stored in the cutting fluid recovery tank 14 for recovery. Specifically, the angle adjusting mechanism 36 is configured so that the cutting fluid E can flow out from the drain hole 12 of the conveying surface 9 of the conveyor body 4 and be discharged at a predetermined time of, for example, about 7 minutes. 9 is inclined downward from the transport downstream side C of the transport surface 9 toward the transport upstream side D, for example, by 5 ° or more and 6 ° or less.

  On the other hand, on the downstream side C of the conveyor body 4 of the conveyor 1, receiving a chip collection line or the like on which the conveyed product A conveyed by the rotation of the screw 15 in the conveyor body 4 is conveyed and discharged. The input port of the member 37 is disposed so as to face the conveyed product outlet 10 located on the downstream side D of the conveyor body 4.

  Next, the function and effect of the illustrated embodiment will be described.

  When a conveyed product A such as swarf discharged from a machine tool or the like is introduced into the arc-shaped conveying surface 9 of the conveyor body 4 from the conveyed product input port 5, the coiled screw 15 is rotated. The locking surface 17 of the peripheral surface portion 16 of the screw 15 conveys the conveyed product A on the conveying surface 9 while pushing it.

  At this time, the transported object A is transported per unit time toward the transport downstream side C of the transport surface 9 while being locked by a predetermined amount corresponding to the height F of the locking surface 17 of the screw 15. It is gradually pushed in a state where the upper limit of is restricted.

  That is, when the transported object A is larger than the height F of the locking surface 17 of the screw 15 on the transport surface 9 of the conveyor body 4, it can be locked by the locking surface 17 of the screw 15. A certain amount of the conveyed product A is pushed, and a certain amount or more of the conveyed product A passes through the hollow portion 17a of the screw 15 and is left behind. Then, it is again locked and conveyed.

  Therefore, by the rotational drive of the screw 15 of the conveying device 1, a predetermined amount of the conveyed product A that can be locked by the locking surface 17 of the peripheral surface portion 16 of the screw 15 is continuously conveyed, and the conveyor body 4 is conveyed. The material is discharged from the object outlet 10 to the receiving member 37. As a result, it is possible to prevent bridge-shaped clogging that occurs when a large amount of the conveyed product A is put into the receiving member 37 as shown in FIG.

  Further, the height F of the peripheral surface portion 16 of the screw 15 of the conveying device 1 is adjusted, the rotational speed of the screw 15 is adjusted, and the inclination angle θ of the conveying surface 9 of the conveyor body 4 of the conveying device 1 is set. By adjusting, it is possible to adjust the transport amount per unit time of the transported object A transported by the rotation of the screw 15.

  Further, a drain hole 12 is provided on the transport upstream side D of the transport surface 9 of the conveyor body 4 of the transport device 1, and the transport surface 9 is directed from the transport downstream side C to the transport upstream side D by the angle adjustment mechanism 36. Since the cutting fluid E is discharged onto the transport surface 9 together with the transported material A and is transported on the transport surface 9, the cutting fluid E is transported on the transport surface 9 of the conveyor body 4 by its own weight. And the outer peripheral surface 18 of the peripheral surface portion 16 of the screw 15 through the gap G between the conveying surface 9 and the upstream side D of the conveying surface 9. The cutting fluid E flows from the drain hole 12 of the conveying surface 9 to the drain pipe 13. And is recovered into the cutting fluid recovery tank 14.

  Therefore, the cutting fluid E discharged from the machine tool together with the conveyed object A on the conveying surface 9 of the conveyor body 4 is separated from the conveyed object A conveyed on the conveying surface 9 and collected. Therefore, the transported object A transported on the transport surface 9 is separated from the cutting fluid E and dried, and the transported object A is transported upstream D of the transport surface 9 by rotating the screw 15 while being dried. Can be transported continuously from the transport toward the transport downstream side C.

  Further, the bolt fixing of the holding frame 33 to the bolt fixing hole 35 by the hinge bolt 32 of the angle adjusting mechanism 36 is loosened, and these holding frames 33 are directed in the vertical direction within the angle adjusting hole 31 of the angle adjusting mechanism 36 of the gantry 25. By appropriately moving, it is possible to adjust the height position of the conveyor body 4 held by these holding frames 33 and the inclination angle θ of the conveyor surface 4 of the conveyor body 4 in the transport direction B.

  Therefore, the height position and the inclination angle θ of the conveying surface 9 of the conveyor body 4 of the conveying device 1 can be adjusted with a simple operation by simply loosening and retightening the two hinge bolts 32 of the angle adjusting mechanism 36. The cutting fluid E discharged on the transfer surface 9 is transferred to the drain hole 12 on the transfer upstream side D while the transfer object A is transferred to the transfer downstream side C by a predetermined amount by the rotation of the screw 15 in the transfer surface 9. The angle can be easily adjusted to ensure the drop.

  Further, even when the installation location of the conveying device 1 changes, the adjuster screw 28a of the height adjusting mechanism 28 is rotated so that the conveyed product A discharged from the machine tool is reliably conveyed. The height position of the conveyance surface 9 of the conveyor body 4 of the apparatus 1 can be easily adjusted.

  Furthermore, since the hollow coiled screw 15 is lighter than a solid screw formed in a spiral shape without opening the central portion, the power consumption of the electric motor 22 for rotating the screw 15 can be reduced. .

  In this way, even if a large amount of the conveyed product A is put into the conveyor body 4, the amount that can be transferred by the hollow coiled screw 15 is limited, and the excess conveyed product A gets over the coiled screw 15 and returns to the original state. Therefore, the present invention can be applied when the supply amount of the conveyed product A is limited. At this time, the screw 15 in which the rod-shaped square member is formed into a coil shape is fitted to the conveyor body 4 on the outer peripheral surface and pushes the conveyed product A on the front surface. Is stable, and a certain amount of the conveyed product A can be efficiently transferred.

  In addition, since the conveyed product outlet 10 is opened on the upper side of the conveyor body 4 installed in an inclined manner and the drain hole 12 for discharging liquid is opened on the lower side, the liquid in the conveyed item A can be discharged. Then, it can be separated to the opposite side of the conveyed product discharge side by its own weight dropping action, and discharged from the drain hole 12 to the outside.

  The height of the conveyor body 4 can be adjusted by the height adjusting mechanism 28 provided on the gantry 25, and the relationship between the height at which the conveyed product A is input into the conveying apparatus 1 and the height at which the discharged material A is received. Optimal state is obtained. Further, by adjusting the inclination angle of the conveyor body 4 by the angle adjusting mechanism 36, the discharge position of the conveyed product A can be adjusted and the supply amount can also be adjusted. Furthermore, the conveyed product A can be automatically transferred by rotating the screw 15 by the screw driving device 20.

  In each of the above-described embodiments, the structure provided with the angle adjusting mechanism 36 that can adjust the height position of the conveying surface 9 of the conveyor body 4 of the conveying device 1 and the inclination angle θ in the conveying direction B has been described. When the cutting fluid E conveyed onto the conveying surface 9 of the main body 4 is conveyed to the conveying upstream side D of the conveyor main body 4 and can be separated from the conveyed product A, the conveying surface 9 of the conveyor main body 4 is not inclined. Can be installed horizontally. Furthermore, a height position adjusting means capable of adjusting the height position of the conveyor body 4 in the width direction can be provided.

  Further, the outer diameter of the peripheral surface portion 16 of the screw 15 is made smaller than the inner diameter of the conveying surface 9 of the conveyor body 4 so that the space between the conveying surface 9 of the conveyor body 4 and the outer peripheral surface 18 of the peripheral surface portion 16 of the screw 15 is reduced. In this configuration, a predetermined gap G is formed and the cutting fluid E discharged onto the conveying surface 9 is passed through the gap G. However, at least a part of the outer peripheral surface 18 of the peripheral surface portion 16 of the screw 15 is used. Further, at least a part of the conveying surface 9 of the conveyor body 4 is provided with a not-shown recess or groove having a concave cross section through which the cutting fluid E can pass, or the peripheral surface portion 16 of the screw 15 and the conveying surface 9 of the conveyor body 4 are decentered. Alternatively, a gap G through which the cutting fluid E can pass may be formed at least partly between the conveying surface 9 of the conveyor body 4 and the outer peripheral surface 18 of the peripheral surface portion 16 of the screw 15.
