Description

Detailed Description of the Invention Generally, when forging materials such as steel materials such as round bars and square bars, a large number of materials are conveyed to the processing site using a conveyor, and the transported materials are air-filled at the processing site. The materials are individually pushed into a heating furnace using a pushing device such as a cylinder, heated in the heating furnace, and successively extruded outside to perform a forging process on the red-hot material. Therefore, in this case, in order for the pushing device, such as an air cylinder, to operate reliably and thereby individually accommodate the materials into the heating furnace, the materials must be placed on the conveyor in a line along the conveyor. It is necessary to ensure that they are received in orderly alignment and delivered to a predetermined position relative to the pushing device and the heating furnace. This material is stored and conveyed in a line along the conveyor not only when the material is subjected to forging, but also when the material is subjected to pressing using a press machine, etc. It is equally important.

In view of this situation, the present invention has been devised to automatically arrange the materials on a conveyor in a line along the conveyor, which is necessary when performing processing such as forging or pressing on the materials without requiring manual labor. By making it possible to ensure that the materials are stored and transported in regular alignment, it is possible to save labor in the work of transporting materials to the processing site and the work of supplying materials to the transport mechanism, and to increase the work efficiency. It is an object of the present invention to provide a material conveying device that can have a simple and compact overall configuration regardless of the length of the material, and can be made as inexpensive as possible.

Accordingly, the present invention provides a quantitative supply mechanism A that supplies a large number of materials such as steel materials inputted from a hopper to a conveying mechanism in predetermined quantities in a relatively large quantity, and a quantitative supply mechanism A that conveys a predetermined amount of materials supplied from the quantitative supply mechanism. A conveyance means having a storage mechanism B that is stored in the mechanism and a material storage path that is wide enough to store a single material.
C ₁ and an alignment means C ₂ for releasing the irregularly arranged materials on the material storage path of the transport means and aligning the materials in a single line on the material storage path. It consists of mechanism C. An example of implementing the present invention will be described with reference to the attached drawings FIGS. 1 to 3. Reference numeral 1 denotes a hopper into which materials 2 such as steel materials are thrown in in bulk, and is provided on the top of a pedestal 3. At the bottom of the hopper 1, a hopper bottom plate 5 with a vibration motor 4 attached to the bottom surface is fixed to the pedestal 3. The receiving plate 6 is provided with a vibration absorbing material 7 such as a coil spring or rubber interposed on the upper surface of the receiving plate 6 so as to be inclined slightly downward toward the exit direction of the hopper. The material fed into the hopper is sent toward the exit by the vibration of the hopper bottom plate 5.
A quantitative supply mechanism A that supplies a predetermined amount of material 2 inputted from the hopper to the conveyance mechanism C in a relatively large quantity is interposed between the hopper 1 and the conveyance mechanism C, and various structures are possible. ,
FIG. 1 shows a cylinder and a piston. That is, in FIG. 1, the cylinder 8 is located in front of the hopper bottom plate 5 at a distance of approximately
It is fixed to the frame 3 with an inclination angle of 45 degrees, and the cylinder 8 has a rectangular cylindrical shape and its transport mechanism C
The side wall of the hopper 1 extends upward longer than the side wall of the hopper 1 (protruding slightly above the hopper bottom plate 5), and a prismatic piston 9 is slidably disposed within the cylinder 8. There is. One end of the crankshaft 10 is connected to the lower side of the piston 9 by a pin.
The other end of the piston 9 is connected by a pin to the outer peripheral edge of a pulley 13 which is connected to a rotating shaft of a motor 11 by a belt 12.
3 causes the conveyor 8 to move up and down, that is, to slide back and forth, on the inner wall surface of the conveyor 8 via the crankshaft 10. The piston 9 is raised and lowered within a range in which the upper surface of the piston 9 does not fall below a position where the upper surface of the piston 9 is approximately at the same height as the hopper bottom plate 5 during the lowering. 14 is the cylinder 8 and the conveyance mechanism C
A chute installed between the conveyor C ₁ and the conveyor C 1 or a vibrating chute with a vibration motor attached to the bottom surface, the conveyor is inclined downwards towards the conveyor C ₁ , and the tip end is connected to the conveyor C 1 . ₁
Facing the top. The bulk material 2 fed into the hopper 1 descends on the hopper bottom plate 5 toward the exit, and when the piston 9 descends, a predetermined amount of material 2 is transferred to the extended surface of the side wall of the cylinder 8 and the piston 9. The piston 9 is accommodated between the piston 9 and the upper surface, and is pushed out onto the chute 14 as the piston 9 rises. Reference numeral 15 denotes an existing vibrating conveyor which is the conveying means C ₁ in the material conveying mechanism C. The belt is connected to a vibrating motor via a connecting arm and attached to a pedestal via a leaf spring. It transports material 2. This vibrating conveyor 15 is located at the other end of the quantitative supply mechanism A (actually, at the front of the chute 14).
A V-groove is disposed in a direction perpendicular to the supply direction of the material 2 supplied from the quantitative supply mechanism A, and a V-groove serving as a material storage path for storing a single material 2 along the longitudinal direction is provided on the upper surface. 16 are formed. In addition, a vibration conveyor 1 serving as a conveying means C ₁
A step portion 17 is formed at the front end of the material 2, and above the step portion 17, a baffle plate 18 having an arc-shaped notch on the lower surface is arranged between the upper surface of the vibrating conveyor 15 and the upper surface of the vibrating conveyor 15. The step portion 17 of the vibrating conveyor 15 and the baffle plate 18 serve as alignment means _C2 in the conveyance mechanism C. Reference numeral 19 denotes a direction changing roller serving as a storage mechanism B for storing a predetermined quantity of materials 2 supplied from the constant supply mechanism A into the conveying means C ₁ of the means mechanism C, and has a screw threaded portion on the outer circumferential surface in the longitudinal direction. 20 is formed to protrude in a spiral shape, and _the material is supplied from the quantitative supply mechanism A along the vibrating conveyor 15 above the opposite end of the chute 14 of the vibrating conveyor 15 serving as the conveying means C1. It is disposed in a direction perpendicular to the supply direction of No. 2. The baffle plate 18 in the alignment means C ₂ protrudes from the bearing of the direction changing roller 19.

The operation of the apparatus according to the above embodiment will now be explained. A large number of materials 2 loaded into the hopper 1 in bulk are sequentially moved toward the outlet by the vibration of the hopper bottom plate 5, and are moved between the extending side wall of the cylinder 8 and the upper surface of the piston 9 in the quantitative feeding mechanism A. When the piston 9 descends, a predetermined amount of material 2 is accommodated in the container, and is pushed out to the chute 14 as the piston 9 ascends. A predetermined amount of material 2 pushed out onto the chute 14 falls along the chute 14 and comes into contact with a direction changing roller 19 serving as a storage mechanism B. Direction changing roller 19
rotates in the direction of the arrow, and has a screw thread portion 20 spirally protruding from its longitudinal outer circumferential surface. Therefore, the material 2 in a predetermined quantity that comes into contact with the direction changing roller 19 is The direction is changed laterally by the feeding action of the screw screw portion 20, and the conveyor belts are accommodated in the V-groove 16 of the vibrating conveyor 15, which is the conveying means _C1 , and are lined up in a line in a lying state along the V-groove 16 within the V-groove 16. By the vibration action of the vibrating conveyor 15, the material is conveyed to a predetermined position relative to a pushing device such as an air cylinder or a press device at the processing site. The vibrating conveyor 15 is formed with a V-groove 16 which is a material storage path with a width that accommodates a single material 2, and the material is usually collected in a predetermined amount by the direction changing action of the direction changing roller 19. 2 are conveyed in a line along a V-groove 16 by a vibrating conveyor 15, but sometimes some of the materials 2 are conveyed in an upright state instead of lying down, or some of the materials 2 are conveyed in a straight line along a V groove 16. In some cases, the materials 2 are transported in an irregularly lined state, such as in a state where one part rides on another material 2 and is overlapped, and in that case, the step part 17 of the vibrating conveyor 15, which is the alignment means, This state is released by the baffle plate 18 and the baffle plate 18. That is, when a part of the material 2 is conveyed in an upright state and reaches the stepped portion 17, the upper end of the material 2 contacts the baffle plate 18, and the lower end contacts the baffle plate 18 and the stepped portion 17. A gap slightly larger than the diameter of the materials is provided between the vibrating conveyors 1 and 1.
Since it is sent forward by the feeding action of 5, it falls from the lower end side along the step 17 and is accommodated in the V-groove 16 of the vibrating conveyor 15 in a lying state along it. Furthermore, when a part of the material 2 is conveyed in an overlapping state on top of another material 2, the upper material 2 is temporarily prevented from traveling by the baffle plate 18, and the lower material 2 After the lower material 2 falls, the upper material 2 falls along the step 17 and similarly lies in the V-groove 16 of the vibrating conveyor 15 along it. be accommodated. Therefore, unlike the case where baffle plates are arranged at predetermined intervals on the top surface of a horizontal vibrating conveyor, the presence of the stepped portion 17 and baffle plate 18 prevents materials from being conveyed upright or overlapping each other. In any case, irregular conditions can be reliably released, and even if materials of considerable diameter and weight are continuously fed, they will not get jammed at the baffle plate. It can be transported smoothly, neatly, and in an aligned state.

FIG. 4 shows another embodiment of the quantitative supply mechanism A, which uses a cylinder and a piston as in the case of FIG. 1, but unlike the case of FIG. The upper surface of a piston 9', which is disposed perpendicularly to the bottom of the hopper at the front and slides back and forth within the cylinder 8', is transferred to the conveying means _C1.
The surface is sloped downward at an angle of about 45 degrees. In this case, the piston 9' moves vertically up and down inside the cylinder 8',
Since the upper surface of the piston 9' is inclined at an angle of about 45 degrees toward the conveying means _C1 , the predetermined amount of material 2 that has fallen into the cylinder 8' from the hopper bottom plate 5 is moved as the piston 9' rises. It is pushed out onto the chute 14.

Also, FIG. 5 shows another embodiment of the quantitative supply mechanism A, and unlike the cases shown in FIGS. 1 and 4, it is not based on a cylinder and a piston, but is based on a rotating operation of a rotary plate. be. That is,
A hook-shaped rotary plate 22 having a downward arc-shaped material stopper plate 21 on the hopper bottom side is disposed in front of the hopper bottom plate 5, and the rotary plate 22 is connected to the hopper bottom plate 5 and the chute 14 by an air cylinder or a hydraulic cylinder 23. It is designed to allow reverse rotation between the two. In this case cylinder 2
When the rod 3 is extended and the rotating plate 22 is at the position shown by the solid line in FIG. When the rod is shortened, the rotary plate 22 rotates counterclockwise as shown by the imaginary line in FIG. Sent out. At this time, the material stopper plate 21 on the rotary plate 22 closes the front of the hopper bottom plate 5, so that the material 2 on the hopper bottom plate 5 is prevented from falling downward.
When the rod of the cylinder 23 is extended again, the rotating plate 22 rotates clockwise from the position shown by the imaginary line in FIG. 5 to the position shown by the solid line, and this operation is repeated.

6 and 7 show other embodiments of the storage mechanism B, and unlike the case shown in FIG.
9' is disposed above the chute 14 side of the vibrating conveyor 15, that is, the hopper 1 side end, and a guide plate 24 is disposed above the opposite end of the vibrating conveyor 15, facing the direction changing roller 19'. is arranged. In this case, a predetermined amount of material 2 falling on the chute 14 in a certain amount first comes into contact with the direction changing roller 19', and is affected by the feeding action of the screw thread part 20' as the direction changing roller 19' rotates. As a result, the respective directions are changed so that they lie sideways, and they are accommodated in a lying state in the V-groove 16 on the upper surface of the vibrating conveyor 15, in contact with the guide plate 24 located in the front.

In the above embodiment, the existing vibration conveyor 15 is used as the conveyance means _C1 in the conveyance mechanism C, but there is no need to limit it to this, and for example, a belt or the like may be rotated between rollers or gears. There is no problem even if a so-called existing belt conveyor or chain conveyor is used. In addition, although a V-groove ₁₆ is shown as the wide material storage path formed on the upper surface of the conveyance means C 1 for accommodating a single material, instead of the V-groove, a V-groove 16 is used along the longitudinal direction of the conveyance means C ₁ . A pair of guide rods may be provided at intervals corresponding to the diameter of the material. In addition, quantitative supply mechanism A
Although the chute 14 is shown interposed between the feed mechanism A and the conveyance mechanism C, this is not necessarily necessary, and the quantitative supply mechanism A and the conveyance mechanism C may be arranged in close proximity. In addition, although the reciprocating sliding operation of the piston 9 in the quantitative supply mechanism A was shown as being performed by a pulley and a crankshaft connected to a motor, as shown in FIG. 'The piston 9 may be connected to the crankshaft 10, or it may be done using existing pressure fluid. moreover,
Although the hopper bottom plate 5 is shown as having a vibration motor attached to its lower surface and sending the material 2 to the quantitative supply mechanism A by vibration, it is not limited to this, and as shown in the eighth figure, one end of the bottom plate 5' can be It may be pivoted to the inner wall of the hopper, and the other end may be pivoted to the upper part of the piston 9. In this case, when the piston 9 descends, the bottom plate 5' rotates counterclockwise around the pivot point with the hopper inner wall, and the angle of inclination becomes steeper, so that the material 2 thrown into the hopper 1 The material 2 falls along the slope of the bottom plate 5' toward the piston 9, and is placed on the upper surface of the piston in predetermined quantities.As the piston rises, the materials 2 are collected in predetermined quantities. is pushed out onto the chute 14, and at this time, the bottom plate 5' rotates clockwise with the hopper 9' to the position of the imaginary line and its inclination angle becomes gentle, so that the material on the bottom plate 5' is pushed out. is prevented from falling onto the upper surface of the piston 9'.

As described above, in the present invention, a large number of materials inputted in bulk from a hopper are sent by a predetermined amount to a transport mechanism C by a constant supply mechanism A, and a storage mechanism B
, the direction of a predetermined amount of material supplied from quantitative supply mechanism A is changed and the material is stored in the material storage path on the upper surface of transport means C ₁ in transport mechanism C, and a part of the material is stored in the material storage path. When the conveyance means C 1 is conveyed in an irregularly lined state, the alignment means C ₂ by forming a stepped portion on the conveying means C ₁ and baffle plates arranged above the stepped portion at a predetermined interval can be used. I made it possible to release the condition by
Even if a large number of materials are continuously fed in bulk from the hopper, a certain amount of materials are always arranged in a line in a reclining state along the material storage path on the upper surface of the conveying means _C1 in a regular manner. In this state, the material is transported to a predetermined position to a pushing device such as an air cylinder and a heating furnace, or to a press device, etc. at the processing site, thus making it possible to efficiently feed materials to the transport mechanism. This method requires manual labor to accommodate and transport the materials in regular alignment in a line along the conveyor, which is necessary when the materials are subjected to processing such as forging or pressing. It is possible to automatically and reliably carry out the process without having to carry the material to the processing site, saving labor in transporting materials to the processing site and increasing work efficiency. It can be transported in a lined state, there is no need to increase the size according to the length of the materials, and the overall structure can be made simple and compact, resulting in the lowest possible price. It can be made at low cost.
