In the following description, a description will be given of a structure in which a material transport apparatus is installed in a material transport apparatus to transport a material. As shown in Fig. 3, the material cutting apparatus 100 may include, for example, a work table 110 on which a work P is placed and transported, and a cutter 120 disposed on one side of the work table 110 to cut the work have. Thus, the workpiece is continuously cut by a cutter while being moved from a workbench, and is made into a specimen of a predetermined size. The material conveying device is installed on the work table of the material cutting device and continuously moves the material to the cutter by a predetermined length. The material conveying apparatus of the present embodiment is applicable to all the facilities for performing the set work by conveying the material in addition to the material cutting apparatus described above.

FIG. 1 and FIG. 2 show the construction of the material conveying apparatus according to the present embodiment.

The material conveying apparatus 10 of the present embodiment has a guide groove 22 through which a work P passes and a slit hole 24 communicating with the guide groove 22 at an upper portion of the guide groove 22 A moving bar 30 disposed above the board frame 20 so as to be movable along the slit hole 24 and a movable bar 30 mounted on the moving bar 30 and movable along the slit hole 24 And a moving part connected to the moving bar 30 and moving the moving bar 30 by a predetermined length along the slit hole 24 .

The board frame 20 is a rectangular plate structure, and a guide groove 22 is formed in a lower portion thereof. In the present embodiment, a plurality of guide grooves 22 may be regularly arranged with an interval therebetween. The number of the guide grooves 22 may be variously modified, and is not particularly limited. The guide grooves 22 are formed at the lower portion of the board frame 20 and both ends thereof are opened to allow the work to move along the guide grooves 22. [ The width of the guide groove 22 may be formed to have a size corresponding to the width of the work P.

Slit holes 24 are formed in the upper surface of the board frame 20 at positions corresponding to the guide grooves 22. The slit hole (24) extends along the guide groove (22).

The material transfer apparatus 10 of the present embodiment further includes a fixing section for fixing the board frame 20 on a work table (see 110 in FIG. 3) of a workpiece cutting apparatus (hereinafter referred to as 100 in FIG. 3) . As shown in Fig. 1, the fixing portion may be installed at both ends of the board frame 20. [ The fixing unit may be a magnetic body 26 mounted on the board frame 20 and attached to the work table by applying a magnetic force thereto.

Usually, the working table of the material cutting device is made of iron material. Accordingly, the magnetic body 26 provided on the board frame 20 is attached to the workbench made of iron by magnetic force, and the board frame 20 is fixed to the workbench.

The magnetic body may be a permanent magnet or an electromagnet. In case of the electromagnet, the magnetic force can be applied or the magnetic force can be removed depending on whether the electric current is applied or not, so that the board frame 20 can be selectively fixed to the work bench as needed. Thus, the board frame 20 can be easily separated from the work table by cutting the current of the electromagnet after the completion of the work by performing the necessary work by fixing the board frame 20 at a proper position by driving the electromagnet.

The adsorption unit is structured to be attached to the work using an air adsorption force. To this end, the adsorption portion of the present embodiment includes an adsorption tube 32 which is installed in the movable bar 30 and extends to the guide groove 22 through the slit hole 24 to adsorb the upper surface of the work P, And a control valve 36 installed on the suction hose 34 and controlling the suction force through the suction hose 34. The suction hose 34 is connected to the suction hose 34,

The suction hose 34 may be connected to a suction pump (not shown) for generating a suction force. The control valve 36 is installed in the suction hose 34 to apply or cut off the suction force through the suction hose 34.

The movable bar 30 is disposed in a direction perpendicular to the work moving direction. The moving bar 30 is extended to both ends of the board frame 20 and the suction pipe 32 is installed at a position corresponding to the slit hole 24, respectively. Therefore, by moving one moving bar 30, it is possible to simultaneously move a plurality of workpieces P placed in each guide groove.

In this embodiment, the travel bar 30 may be, for example, an empty pipe structure. A suction hose (34) is connected to one end of the moving bar (30) to be connected to an inner channel of the moving bar (30). A suction pipe (32) is connected to the lower end of the movable bar (30). When a suction force is applied to the inside of the movable bar 30 through the suction hose 34, a suction force is applied to each suction pipe 32 provided in the movable bar 30 and communicated with the inside thereof. Accordingly, when the front end of the adsorption tube 32 is in close contact with the surface of the work P, a vacuum pressure is formed therein, and the work P is adsorbed and attached to the adsorption tube.

As described above, by attaching the workpiece to the suction tube 32, the workpiece can be moved by moving the movement bar 30.

The suction pipe 32 is a part which is in contact with the material P and may further include a sucker 33 for increasing the adherence to the material at the tip thereof to increase the suction force. The suction plate 33 may be, for example, a circular plate structure made of a rubber material.

The moving unit is configured to move the moving bar 30 repeatedly by the same length in the material moving direction. The moving unit may include a driving cylinder 40 installed on the board frame 20 and disposed in a material moving direction and connected to the moving bar 30 to move the moving bar.

The drive cylinder 40 can be driven by air pressure or hydraulic pressure. Reference numeral 41 in FIG. 2 is a support bracket for mounting the drive cylinder 40 on the board frame 20.

When the driving cylinder 40 is stretched and driven, the moving bar 30 connected to the distal end of the piston rod 42 of the driving cylinder 40 is moved along the work moving direction. The suction pipe 32 provided on the movable bar 30 is attached to the work P via the slit hole 24 so that the work P is moved along the guide groove 22 as the movable bar 30 moves .

In addition, the apparatus of the present embodiment has a structure for adjusting the height of the moving bar 30 according to the thickness of the material P. Thus, interference between the adsorption tube 32 and the workpiece can be prevented, regardless of the thickness of the workpiece P, and the adsorption force can be increased by positioning the adsorption tube 32 on the workpiece P surface.

For this purpose, the material conveying apparatus 10 includes a vertical moving part for adjusting the height of the moving bar 30. [ The upper and lower portions of the upper and lower portions of the movable bar 30 are vertically extended on the upper portion of the moving bar 30 and are mounted on the guide holder 44 And a vertical member 46 that is slidably mounted.

Thus, the vertical bar 46 can be moved up and down along the guide holder 44 to move the bar 30 provided with the vertical bar 46 in the vertical direction in accordance with the thickness of the work P.

The lower end position of the suction pipe 32 provided at the lower end of the movable bar 30 is varied by moving the movable bar 30 up and down with respect to the guide holder 44. [ The movable bar 30 is moved up and down according to the thickness of the workpiece P moved along the guide groove 22 of the board frame 20 so that the position of the suction tube 32 is positioned on the upper surface of the workpiece P . Therefore, regardless of the thickness of the material, the adsorption tube 32 can be brought into close contact with the work P, and the adsorption force can be applied.

Here, the guide holder 44 may have a polygonal cross-sectional structure, and the vertical member 46 may have a polygonal cross-sectional structure corresponding to the guide holder 44. As the guide holder 44 and the vertical member 46 have a non-circular cross-sectional structure, rotation of the vertical member 46 relative to the guide holder 44 is prevented. This makes it possible to prevent the movable bar 30 from rotating about the vertical member 46 with respect to the guide holder 44 when the movable bar 30 moves according to the extension and retraction of the drive cylinder 40. [ Therefore, it is possible to linearly move the movement bar 30 along the slit hole 24 by the same length as the whole, and to move all the materials located in the guide grooves 22 by a fixed amount by the same length.

Hereinafter, with reference to Fig. 3, an operation of continuously transferring a workpiece by a fixed amount to the workpiece transferring apparatus of this embodiment will be described. Reference numerals not shown in Fig. 3 refer to Figs. 1 and 2. Fig.

The workpiece conveying device 10 of the present embodiment is fixedly mounted on the workbench 110 of the workpiece cutting device 100. [

When the board frame 20 of the material conveying apparatus 10 is fixed to the work platform 110, the work P is moved through the guide grooves 22 formed in the lower portion of the board frame 20. When the workpiece P is inserted into the guide groove 22 and placed on the work table 110, the workpiece conveying device 10 of the present embodiment is driven to continuously convey the workpiece P in a fixed quantity and cut to a predetermined size .

The control valve 36 is controlled and operated to apply a suction force to the suction pipe 32 of the movable bar 30 when the workpiece conveying device 10 is driven in a state where the work P is fitted and fixed in the guide groove 22 do. The material is attached to the adsorption tube 32 by the adsorption force of the adsorption tube 32.

The driving cylinder 40 is operated in a state in which the material P is attached to the suction pipe 32, so that the piston rod 42 is stretched. The movable bar 30 moves toward the cutter 120 as the drive cylinder 40 is extended. The material P is moved toward the cutter 120 like the moving bar 30 as the moving bar 30 moves while being attached to the suction pipe 32 of the moving bar 30. [

Thus, by moving the drive cylinder 40 to extend by a predetermined length, the work P can be moved toward the cutter 120 by a predetermined amount.

The workpiece P is moved and the cutter 120 is driven to cut the workpiece. After the material is cut, the driving cylinder 40 is continuously stretched to continuously move the workpiece P in a fixed quantity, and the cutter is also repeatedly driven to cut the workpiece that has been moved in a fixed amount.

The workpiece P can be continuously cut to a predetermined size by repeatedly driving the workpiece P by a constant amount of movement of the drive cylinder 40 and driving the cutter 120 repeatedly in accordance with the movement of the workpiece. By moving the workpiece by the drive cylinder 40 to the same length and cutting it, it becomes possible to continuously produce the specimen by cutting the workpiece in the same standardized size.

When the drive cylinder 40 is fully extended, the control valve 36 is driven to remove the suction force applied to the movable bar 30. [ The adsorption force for the material P is reduced, and the adsorption tube 32 and the material are separated. When the driving cylinder 40 is contracted in a state where the material and the adsorption pipe 32 are separated from each other, the movable bar 30 moves backward and returns to its original position. The movable bar 30 can be moved up and down so that the movable bar 30 can be lifted by moving the vertical member 46 upward relative to the guide holder 44 when the movable bar 30 is retracted. Accordingly, the suction tube 32 provided at the lower part of the moving bar 30 is separated from the upper surface of the material, and the moving bar 30 can be moved to the original position without interfering with the material. When the driving bar 40 is completely contracted and the moving bar 30 is moved to the original position, the above process is repeated to move the workpiece again, so that the workpiece can be continuously cut.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
