However, as shown in FIG. 13, the conventional material replenishing device 100 has a storage section 101 in which a plurality of materials 3 are stored in alignment along the longitudinal direction and a kicker attached to the bottom surface of the storage section 101 so as to be vertically movable. (elevating member) 102, and by raising the kicker part 102, only one material 3 located on the upper surface of the kicker part 102 is raised and sent to the bar feeder through the supply port 103. However, as shown in FIG. 14, since a plurality of kicker portions 102 are arranged at predetermined intervals along the longitudinal direction of the material 3, when an arbitrary material 3 is not taken out by all the kicker portions 102 at the same time, , only the part of the material 3 taken out by the kicker part 102 of a part rises, and it may become the taking-out failure.

Various causes are conceivable for this failure to take out. For example, when taking out a bar with a thin wire diameter, when a plurality of materials 3 are stored, they are twisted with each other without being maintained in alignment. In some cases, it is conceivable that this twisting prevents all kickers 102 from picking up a particular material 3 .

In addition, in the event of an unsuccessful ejection, even if the kicker part is lowered, the material that was unsuccessfully ejected returns to the storage unit in a twisted state. It was necessary to align the materials stored in the storage unit each time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems. Even in such a case, it is possible to prevent twisting of the materials stored in the storage unit in an aligned state, and to adjust the alignment state when twisting occurs, and to check whether the kicker unit is properly taking out the materials. It is an object of the present invention to provide a material replenishing device that can discriminate.

In order to solve the above problems, a material replenishing device according to the present invention is a material replenishing device for replenishing a bar feeder with bars or the like as materials, wherein the materials are stored in an aligned state along the longitudinal direction. and a supply port for supplying the material, which is attached so as to be vertically movable from the bottom surface of the storage unit toward the supply port, and a plurality of materials are arranged at predetermined intervals along the longitudinal direction. a kicker section, a plurality of detection sections arranged near the upper end of the kicker section in a state where the kicker section is raised to the maximum and other than the kicker section , and arranged substantially horizontally corresponding to each of the kicker sections; A movable stopper part is provided so as to be able to move freely in and out in a direction intersecting the up-and-down direction of the part, and to return the material to the storage part when the material raised by the kicker part fails to be taken out. .

Further, in the material replenishing device according to the present invention, it is preferable to include a stirring lever portion having one end attached to the bottom surface so as to be able to swing and the other end arranged so as to be able to move up and down as the kicker portion moves up and down. be.

Further, in the material replenishing device according to the present invention, it is preferable that the other end of the stirring lever portion is capable of coming into contact with an engaging portion formed on the kicker portion.

In the material replenishing device according to the present invention, the movable stopper portion moves in a direction of protruding into the storage portion after the kicker portion is raised, and moves in a direction of retreating from the storage portion after the kicker portion is lowered. It is preferable to move.

Further, in the material replenishing device according to the present invention, the movable stopper portion moves toward the direction of protruding into the storage portion and is placed on the kicker portion when at least one of the detection portions does not detect the material. It is preferred to return the depleted material to the storage.

According to the present invention, since the kicker section is provided with a plurality of detectors arranged substantially horizontally, it is possible to automatically determine whether or not the material taken out from the material bundle is correctly taken out.

In addition, since the stirring lever part that swings as the kicker part moves up and down is attached to the bottom surface of the storage part, the twisting of the material bundle is prevented by arranging the alignment of the materials, and the kicker part can properly take out the material bundle. operation can be realized.

A material supply device 1 according to the present embodiment supplies materials to a material supply machine 2 that supplies materials to a material processing machine called a lathe as an example. 2 are located adjacent to each other.

As shown in FIG. 1, the material supply device 1 includes a main body 5 that supplies bars as materials to the material supplier 2, and a base 7 that supports the main body 5 at a predetermined height.

As shown in FIG. 2, the main body 5 opens and closes a cover portion (not shown) to supply a plurality of long materials 3 from the outside, and stores the plurality of long materials 3 in an aligned state along the longitudinal direction. a storage unit 11, a kicker unit 14 attached to the bottom surface 13 of the storage unit 11 so as to be vertically movable in the height direction, a detection unit 15 located near the upper end when the kicker unit 14 is raised to the maximum, and a material from the vicinity of the upper end. It has a slope 17 extending toward the supply device 2 and a supply port 12 for supplying material to the material supplier 2 via the slope 17 .

The kicker part 14 moves up and down so as to extend upward from the bottom surface 13, thereby taking out one material from the bundle of the materials 3 stored in the storage part 11 and lifting the material 3 taken out to one end of the slope 17. - 特許庁. At this time, since the kicker portion 14 is tilted toward the storage portion 11 side from the vertical direction and ascends and descends, even when a plurality of materials are placed on the upper end of the kicker portion 14 as the kicker portion 14 rises, the upper end of the kicker portion 14 does not move. Materials other than the materials in contact with each other are dropped into the storage section 11 so that only one material can be taken out.

Further, the bottom surface 13 of the storage section 11 is formed so as to be inclined downward toward the kicker section 14, so that the material bundle stored in the storage section 11 moves toward the kicker section 14 by its own weight. ing. Thereby, after one material 3 is taken out by the kicker part 14, the remaining material moves to the side of the kicker part 14 and prepares for the next take-out.

Further, as shown in FIG. 3 , a plurality of kicker portions 14 are arranged at predetermined intervals along the longitudinal direction of the material 3 , and even if the material 3 is a wire rod with a small diameter, the material 3 has its own weight. It is possible to lift it almost horizontally without bending in a bow shape.

Further, the detection units 15 are arranged substantially horizontally at predetermined intervals corresponding to the kicker units 14 . The detection unit 15 may adopt any configuration as long as it can detect the presence or absence of the material 3 taken out by the kicker unit 14. For example, it is preferable to use a proximity sensor.

As described above, the material replenishing device 1 according to the present embodiment includes the detection units 15 corresponding to the respective rising ends of the kicker portion 14. Therefore, when the material is properly placed on the kicker portion 14, all Since the detection unit 15 is turned on at the same time, it is possible to determine that the material has been correctly taken out from the storage unit in this case. In FIG. 3, the case where a plurality of kicker units 14 and detection units 15 are arranged at approximately equal intervals has been described. They may be arranged at uneven intervals by appropriately adjusting the intervals according to their positions.

Further, as shown in FIG. 5, in a state in which the materials 3 are not properly placed on all the kicker portions 14 and take-out failure occurs, the detection portions 15 corresponding to the kicker portions 14 on which the materials 3 are not properly placed (see FIG. 5 Since the two central detectors 15) in 1 do not turn on, it can be determined that an ejection failure has occurred in this case. When it is determined that the material 3 has been unsuccessfully taken out, the movable stopper portion 16 (to be described later) returns the unsuccessfully taken out material 3 to the storage portion 11 .

As shown in FIG. 4 , a movable stopper portion 16 having a substantially L shape is attached near the kicker portion 14 . The movable stopper portion 16 is preferably arranged at least between the kicker portions 14 , and is attached so as to be movable in a direction intersecting the upward/downward direction of the kicker portion 14 . It is configured to move in a projecting direction and in a retracting direction from the storage portion 11 . In addition, the movable stopper portion 16 is configured so as not to protrude toward the storage portion 11 from the end surface of the kicker portion 14 on the storage portion 11 side when moved in the direction of protruding toward the storage portion 11 .

The movable stopper portion 16 includes a push-out portion 16a extending along the lifting direction of the kicker portion 14 and a base portion 16b extending horizontally from the lower end of the push-out portion 16a. When taking out the material 3, the material 3 is guided in the vertical direction. At this time, the position of the push-out portion 16a is such that the kicker portion 14 protrudes toward the storage portion 11 side according to the material diameter of the material 3 to be taken out so that the kicker portion 14 can take out the material 3. The position of the movable stopper 16 is adjusted so as to be substantially the same as or slightly larger than the material diameter of . Further, as shown in FIG. 6 , when the detection unit 15 determines that the material 3 is unsuccessful, the movable stopper unit 16 moves so as to push out the material 3 toward the storage unit 11 , and the material on the kicker unit 14 is pushed out. 3 can be returned to the storage unit 11 .

Next, as shown in FIGS. 7 and 8 , a stirring lever portion 19 is attached to the storage portion 11 so as to be swingable with respect to the bottom surface 13 . One end of the stirring lever portion 19 is attached to the swing shaft 21 so as to be able to swing, and the other end is disposed so as to be able to come into contact with a projecting engaging portion attached to the kicker portion 14 . As shown in FIG. 8, the stirring lever portion 19 is lifted toward the storage portion 11 as the other end of the stirring lever portion 19 comes into contact with the engaging portion 18 as the kicker portion 14 moves up and down. The stirring lever portion 19 is supported by the stopper 20 and accommodated in a state substantially parallel to the bottom surface 13 when the kicker portion 14 is retracted downward. The engaging portion 18 may have any shape as long as it is a protrusion capable of coming into contact with the other end of the stirring lever portion 19. For example, it is preferable to use a cam follower or the like.

In this way, since the stirring lever portion 19 swings as the kicker portion 14 moves up and down, the bundle of materials 3 is moved to one side (right side in FIG. 8) of the storage portion 11 and aligned while the kicker portion 14 moves up and down. condition can be adjusted. It is preferable that the engaging portion 18 attached to the kicker portion 14 can change its attachment state so as not to come into contact with the stirring lever portion 19 . With this configuration, it is possible to select to adjust the aligned state of the bundle of materials 3 by the stirring lever portion 19 as necessary.

Next, the operation of the material supply device 1 according to this embodiment will be described with reference to FIGS. 9 to 12. FIG. As shown in FIG. 9 , the kicker part 14 is raised to take out one material 3 from the bundle of materials 3 stored in the storage part 11 . At this time, the movable stopper portion 16 is retracted toward the supply port 12 so that the pushing portion 16a guides the material 3. As shown in FIG. The position of the movable stopper 16 at this time is adjusted to a position where the amount of protrusion of the kicker portion 14 toward the storage portion 11 side is substantially the same as or slightly larger than the material diameter of the material 3, as described above. .

Here, when all of the detection units 15 are turned on at the same time by the detection units 15 described above, the taken-out material 3 is raised to the slope 17 and supplied from the supply port 12 to the material feeder 2 (not shown).

Next, as shown in FIG. 10 , after the material 3 is supplied, the movable stopper portion 16 is moved toward the storage portion 11 and moved to substantially the same position as the end surface of the kicker portion 14 on the storage portion 11 side. At this time, the bundle of materials 3 stored in the storage unit 11 may be moved slightly toward one side of the storage unit 11 (the right side in FIG. 10), or the bundle of materials 3 may be moved to a position where it is not moved. I don't mind. As shown in FIG. 11, after the kicker portion 14 is lowered while the movable stopper portion 16 is moved toward the storage portion 11, as shown in FIG. It is possible to prevent the bundle of materials 3 from being disturbed due to the forceful movement of the bundle of materials 3 to the left side of the storage section 11 (material take-out position) due to the descent of the section 14 . At this time, by moving the movable stopper part 16 to the retracted position at a slow speed, the bundle of materials 3 can be moved to the material take-out position without disturbing the aligned state of the bundle of materials 3.例文帳に追加

9, the material 3 can be returned to the storage portion 11 by the movable stopper portion 16 described above when it is determined that the material 3 has been unsuccessfully taken out. The alignment of the bundle of materials 3 may be arranged by adjusting the joining portion 18 and swinging the stirring lever portion 19 . When the stirring lever portion 19 is swung to align the bundle of the materials 3, the movable stopper portion 16 is moved toward the storage portion 11 side, so that even if the kicker portion 14 is raised, the kicker portion 14 is Only the agitation of the bundle of material 3 can be performed without taking out the material 3 by means of .
