Description

[Detailed Description of the Invention] This invention relates to an automatic dispensing device for dispensing bar-shaped materials such as round billets and materials with circular cross sections such as steel pipes to predetermined locations.

For example, when round billets are loaded into various types of equipment such as seamless steel pipe manufacturing equipment, a large number of round billets stored on racks or the like are usually bundled together with wires and then lifted and transported. On the other hand, since the inserted round billets are handled one by one, such as inspection and charging into the heating furnace, it is necessary to use wires to charge the transported round billets one by one into the equipment. Conventionally, a dispensing device has been used that collapses a large number of removed round billets into piles and arranges them one by one in parallel. FIG. 1 is a diagram schematically showing a conventional automatic dispensing device, in which stoppers 2, 3, and 4 are provided at the upper, middle, and lower parts of the inclined skid 1, respectively.
The upper and middle stoppers 2, 3 are attached to rotating shafts 5, 6 arranged below the upper surface of the skid 1, and the rotating shafts 5, 6 are connected to hydraulic cylinders 7, 8. The skid 1 is configured to be tilted toward the lower side by rotating the skid 1 via levers 9 and 10. The lower stopper 4 also has a function as a guide member, and the lower part of the skid 1 has a rotating arm 12 that scoops up the round billets 11 on the skid 1 one by one and sends them forward along the lower stopper 4. It is located. A large number of round billets 11, which have been bundled and lifted by wires 13 and transported, are lowered onto the upper part of the skid 1, and then moved to the above-mentioned stopper 2.
Remove the wire 13 while supporting it. In this state, the round billets 11 are piled up in a heap, and by tilting the upper stopper 2 by the hydraulic cylinder 7, the round billets 11 begin to roll on the skid 1, resulting in what is called a heap. A round billet 11 is lined up between the end and the stopper 3 in the middle. Then, by tilting the intermediate stopper 3 using the hydraulic cylinder 8, the round billet 11 further rolls on the skid 1, and the round billet 11, which is prevented from rolling by the lower stopper 4, continues to rotate as described above. The arm 12 scoops up and sends one by one to the front of the stopper 4 at the bottom, starting from the frontmost one.

However, the round billets 11 bundled with wires 13 and lowered onto the skid 1 are not necessarily parallel to each other because the external forces that act upon them when they are lifted or lowered onto the skid 1 are irregular and complex. , the end of one of the round billets 11 may get under another round billet 11, and the round billets 11 stacked in a pile can be prevented from interfering with each other by tilting the top stopper 2. It collapses irregularly. Therefore, the collapsed round billet 11 is not at right angles to the skid 1,
In such a case, the lower end of the inclined round billet 11 hits the preceding round billet 11 or the stoppers 3 and 4, and the round billet 11 stops. As a result, the round billets 11 cannot be arranged in close contact with each other in parallel. When such a situation occurs, the rotary arm 12 rotates the round billet 1.
Since it becomes impossible to scoop up the round billet 11, it is necessary for the worker to get on the skid 1 and correct the direction of the round billet 11.

In this way, with the conventional device shown in Fig. 1, it is not possible to completely eliminate the work performed by the operator.
It is difficult to automate, and not only does it place a heavy burden on workers, but it also poses safety problems.

This idea was made in view of the above circumstances, and it is possible to use a large number of target materials with circular cross sections such as round billets.
It is an object of the present invention to provide an automatic dispensing device that can automatically dispense one stick at a time at right angles to the rolling direction. The feature of this invention is that a tilting arm whose upper end moves toward the winding machine is placed at a predetermined distance from the winding machine that winds up filamentary objects such as chains or wires, and that the tilting arm is A frame having an upwardly open shape that engages the end of the filament at its upper end, has a slit through which the filament passes toward the back side, and accommodates a large number of target materials, is attached to a hoisting machine. and the tilting arm,
Further, a stopper is provided to prevent the tilting arm from tilting beyond a predetermined angle, and a skid is provided that slopes downward from the hoist, so that the filament in a relaxed state located on the back side of the frame is transferred to the hoist. By winding up the frame, the arms on both sides are tilted, and at the same time, the object material of the frame is lifted up by the filament and sent to the skid.

An embodiment of this invention will be described below with reference to FIGS. 2 and 3. FIG. 2 is a partially sectional front view of an embodiment of this invention, and the automatic dispensing device shown here uses a round billet 11 as a target material and is configured to be movable. That is, a frame 22 for accommodating a large number of round billets 11 is provided at the center of the upper surface of a self-propelled cart 21 that runs on rails 20. The frame 22 accommodates the round billet 11 facing the running direction of the trolley 21, and as shown in FIG. The frame 22 has a structure in which structural members such as steel plates are arranged in parallel at regular intervals.
has an overall shape that opens upward, and
The structure is such that slits penetrating from the back side to the front side (from the bottom side to the top side in FIG. 2) are formed at regular intervals. Note that the frame 22 has one end (the left end in FIG. 2) set lower than the other end, and a motor (not shown) as a hoist is installed near the lower end. A drive shaft 23 rotated by
1, that is, in a direction parallel to the round billet 11 within the frame 22. The chain sprocket 24 is attached to the frame 22 at a position corresponding to the slit. On the other hand, on the other end side of the frame 22 and on the back side of the frame 22, a tilting arm 26 whose lower end is engaged with a shaft 25 arranged on the upper surface of the truck 21 facing the traveling direction of the truck 21 is arranged. , the end of a chain 27 is attached as a filament to the upper end of the tilting arm 26. Tilting arm 26
is disposed at a position corresponding to the slit in the frame 22, and the chain 27 is wound around the chain sprocket 24, so that when the chain 27 is in a relaxed state, it passes through the slit in the frame 22. By rotating the chain sprocket 24 located on the back side and pulling the chain 27, the chain 27 is pulled out from the back side of the frame 22 through the slit to the front side, and at the same time, the tilting arm 26 is pulled out from the chain sprocket. It is configured to tilt toward the 24 side. Note that the other end of the chain 27 is
It is locked to a fixing pin 28 provided on the opposite side of the frame 22 with the drive shaft 23 as the center, and between the fixing pin 28 and the chain sprocket 24 there is a vertically movable shaft along a guide 29. A floating sprocket 31 having a counterweight 30 is provided, and the chain 27 is wound around the floating sprocket 31 from below. Therefore, as the chain 27 is wound up by the chain sprocket 24, the floating sprocket 31 is lowered by the weight of the counterweight 30, thereby absorbing the slack in the chain 27.

Furthermore, a cylinder 32 is disposed behind the tilting arm 26 to rotate the tilting arm 26 back. The cylinder 32 has a tube 33
Insert the rod 34 into the tube 3.
A spring 35 provided in the rod 34
The tube 33 is pinned to a predetermined fixed portion of the truck 21, and the tip of the rod 34 is pinned to the tilting arm 26. Further, a stopper 36 is provided on the cart 21 to abut on a predetermined location of the tilting arm 26 to restrict the tilting arm 26 from tilting beyond a certain angle.

And the skid 3 that rolls the round billet 11
7 is arranged so as to be inclined downward toward the side opposite to the frame 22 with its upper end near the chain sprocket 24. In addition, this skid 37
Equipment for charging round billet 11 (not shown)

1, and is configured as a short skid whose tip is close to the end of the sloped skid 38.

Next, the operation of the apparatus configured as described above will be explained. First, the chain 27 is sent to the tilting arm 26 side by the chain sprocket 24 and loosened, so that the tilting arm 26 is held in the position shown by the solid line in FIG. 2 by the elastic force of the spring 35 in the cylinder 32. , and the chains 27 are left slack toward the back side of the frame 22. In this state, the floating sprocket 31 is pulled up to its upper limit. The round billet 11 to be loaded into equipment not shown is a wire (not shown)
The frame 22 is bundled together and lifted up.
After that, remove the wire and attach it to frame 2.
Contained within 2. In that case, even if one end of a so-called sling wire is removed from the hook of the crane (each not shown) and the wire is pulled up, the chain 27 will be located on the back side of the frame 22, and the wire will remain attached to the chain 27. It does not get entangled with the . Further, the large number of round billets 11 from which the wires have been removed are once piled up on the frame 22. Next, when the drive shaft 23 is rotated by the motor, the chain sprocket 24 is rotated counterclockwise in FIGS. It begins to rise from the back side to the front side,
As a result, it comes into contact with the round billet 11 on the frame 22. In that case, the entire weight of the round billet 11 is applied to the cylinder 3 for returning the tilting arm 26.
2, the tilting arm 26 is pulled by the chain 27 and tilts as shown in FIG.
And when it is tilted by a predetermined angle, it comes into contact with the stopper 36. In this state, the upper end of the tilting arm 26, ie, one end of the chain 27, is located above approximately the center of the frame 22. Therefore, when the chain 27 is further wound up by the chain sprocket 24, the round billet 11 is lifted from the frame 22 by the chain 27 as shown in FIG. Force acts in the direction of twisting and bundling. As a result, while the round billets 11 are being lifted by the chain 27, their postures are gradually corrected so that the gaps between them become narrower. In other words, the round billets 11 are arranged in parallel with each other and in contact with each other. change.

Round billet 11 lifted in this way
is gradually pushed up to the upper end of the skid 37, and therefore, among the round billets 11 lifted by the chain 27, those that have passed above the chain sprocket 24 fall onto the skid 37, and as a result, The round billets 11 can be dispensed one by one. Furthermore, as described above, each round billet 11 that has been paid out rolls smoothly on the skids 37 and 38 because its posture has been corrected so that it is perpendicular to the rolling direction. Finally, the chain 27 is stretched linearly between the chain sprocket 24 and the upper end of the tilting arm 26 as shown by the chain line in FIG. can be paid out.

In addition, the chain 27 wound up by the chain sprocket 24 and sent to the fixed pin 28 side is
By lowering the floating sprocket 31, it is maintained in a constant shape, so that problems such as entanglement do not occur.

After the round billet 11 is removed, the chain sprocket 24 is rotated in the opposite direction to that described above to feed the chain 27 to the frame 22.
The tilting arm 26 is rotated back to its original position by the elastic force of the spring 35 in the cylinder 32, and then the chain 27 passes through the slit in the frame 22 and enters the rear side of the frame 22, so that the round billet 11 is returned to its receiving state.

In the above embodiments, round billets were used as the target material, but the device of this invention can also be used for dispensing cylindrical materials such as steel pipes. In addition, with this invention, a wire or the like can be used in addition to the chain shown in the above embodiment as the filament for hoisting the target material from the frame, and a drum rotated by a motor can be used as a hoist. You can also use In that case, it is preferable to provide some means so that when the filamentous body such as a wire is relaxed, the filamentous body passes through the slit of the frame and enters the back side of the frame.

As explained above, in the device of this invention, a tilting arm whose upper end moves toward the winding machine is arranged at a predetermined distance from the winding machine that winds up a filament such as a chain or wire, and the tilting arm The upper end of the frame is engaged with the end of the filament, and the frame has a slit through which the filament passes toward the back side, and is open upward and accommodates a large number of target materials. A stopper is provided between the machine and the tilting arm to prevent the tilting arm from tilting beyond a predetermined angle, and a skid is provided that slopes downward from the hoist and is located on the back side of the frame. At the same time as tilting the tilting arm by winding up the filamentous body in a relaxed state with a winding machine,
Because the material is lifted up on the frame by the filament and sent to the skid,
Since a force is applied to the target materials in the direction of bundling by lifting them, the target materials can be arranged perpendicular to the rolling direction, and since they are fed one by one to the skid in this state, the target materials can be rolled smoothly. Then, the skid shape is rolled into a predetermined position.
Therefore, since the device of this invention does not require any special manual work by the operator, it can automate the charging into designated equipment such as round billets, and can avoid dangerous tasks such as adjusting the posture of the target material on the skid. Work can be eliminated.
