Description

[Detailed Description of the Invention] Generally, when forging, pressing, etc. are performed on materials such as steel materials such as round bars and square bars, a large number of materials are housed in a regular row on a conveyor at the processing site 1. At the processing site, the transported materials are individually pushed into a heating furnace using a pushing device such as an air cylinder, heated, and then taken out from the heating furnace and forged. The obtained materials are sequentially and individually pressed using a press machine or the like.

Therefore, in this case, the material transport device automatically and reliably stores and transports a large number of materials in a regular line on the conveyor without the need for manpower, thereby saving labor on material transport work and increasing transport work efficiency. In order to increase the amount of material, a mechanism is required that automatically supplies a predetermined amount of a large number of materials to a conveyor or the like in a material transport device in a line-up state.

The present invention fully satisfies the technical problem of automatically supplying a predetermined amount of a large number of materials to a conveyance means in line with a predetermined amount, which is required in such a material conveyance device. A material feeding mechanism in a material conveying device that can have a simple and compact structure without the need to increase the size of the mechanism depending on the length of the material, and can keep the price as low as possible. The purpose is to provide

Accordingly, the present invention provides a material transport device that stores a large number of materials such as steel materials input from a hopper in a transport means and transports them to a predetermined location via the transport means. A quantitative supply means is provided for supplying a predetermined amount of a large number of materials inputted to the conveyance means to the conveyance means, the conveyance means is disposed in a direction perpendicular to the direction in which the materials are supplied by the constant supply means, and the constant supply means of the conveyance means is provided. Above the end on the opposite side, a direction changing roller is arranged along the longitudinal direction of the conveying means, with a screw thread part protruding in a spiral shape on the outer peripheral surface in the longitudinal direction, and rotating in a counterclockwise or clockwise direction. It is characterized by the fact that

An example of implementing the present invention will be described with reference to the attached drawings.

Reference numeral 1 denotes a hopper into which materials 2 such as steel materials are loaded in bulk, and is installed on the top of a pedestal 3. At the bottom of the hopper 1, there is a hopper bottom plate 5 with a vibration motor 4 attached to the bottom surface.
is provided on the upper surface of a receiving plate 6 fixed to the pedestal 3 via a vibration absorbing material T such as a coil spring or rubber so as to be inclined slightly downward toward the exit of the hopper.

The material 2 put into the hopper is sent toward the outlet by the vibration of the hopper bottom plate 5.

At the front of the hopper bottom plate 5, a cylinder 8 is fixed to the pedestal 3 and has an inclination angle of about 45 degrees with respect to the bottom of the hopper 1 in order to push the material 2 toward the conveyor side, which is a conveying means. A piston 9 is slidably disposed within the cylinder 8.

The cylinder 8 has a rectangular cylindrical shape, and its side wall on the side of the conveyor extends upward as long as the side wall on the side of the hopper 1 (protruding slightly above the hopper bottom plate 5).
The piston 9 sliding inside has a prismatic shape corresponding to the shape of the cylinder 8.

One end of a crankshaft 10 is connected to the lower side of the piston 9 by a pin, and the other end of the crankshaft 10 is connected to the outer peripheral edge of a pulley 13 connected to a rotating shaft of a motor 11 by a belt 12. are connected.

Therefore, the piston 9 moves up and down, that is, slides back and forth, on the inner wall surface of the cylinder 8 via the crankshaft 10 as the pulley 13 rotates.

As shown in the first figure, the piston 9 is raised and lowered within a range where the upper surface of the piston 9 does not fall to 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 a vibrating chute placed between the cylinder 8 and the conveyor, or a vibrating chute with a vibrating motor 9 attached to the bottom surface, and is inclined downward from the cylinder 8 side to the conveyor side. Facing the top.

The bulk material 2 loaded 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 between the extended surface of the side wall of the cylinder 8 and the upper surface of the piston 9. A predetermined amount of material is pushed onto the chute 14 as the piston 9 rises.

Reference numeral 15 designates an existing vibrating conveyor as a conveying means, in which a belt is connected to a vibrating motor via a connecting arm and attached to a pedestal via a plate spring, and conveys the stored materials 2 by the vibration of the belt.

The vibrating conveyor 15 carries the material 2 supplied in a direction perpendicular to the chute 14, that is, from the fixed quantity supply means, to the front of the chute 14, which is disposed in front of the cylinder 8 and piston 9, which are fixed quantity supply means. A groove 16 is formed in the upper surface of the belt in a direction perpendicular to the supply direction and has a width for accommodating a single material 2 along the longitudinal direction.

Further, a step portion 17 is formed at the front end of the vibrating conveyor 15, and above the step portion 17, a baffle plate 18 having an arc-shaped notch on the lower surface is used to hold materials between the upper surface of the vibrating conveyor 15 and the upper surface of the vibrating conveyor 15. They are arranged at intervals slightly larger than the diameter of 2.

Reference numeral 19 denotes a direction changing roller for arranging and accommodating the used amount of material 2 supplied by the cylinder 8 and piston 9, which are quantitative supply means, in a line in the V-groove 16 of the vibrating conveyor 15, which is a conveying means. The material 2 is supplied from the quantitative supply means along the vibrating conveyor 15 above the end opposite to the chute 14 of the vibrating conveyor 15, which has a screw thread portion 20 protruding spirally on the outer circumferential surface. It is arranged perpendicular to the direction.

The baffle plate 18 projects from the bearing of the direction changing roller 19.

Now, a description will be given of a state in which materials 2 such as steel materials are transported to a processing site by the mechanism according to the above embodiment and the transport device connected thereto.

Numerous materials 2 loaded in bulk into hopper 1
is sequentially moved toward the outlet by the vibration of the hopper bottom plate 5, and when the piston 9 descends, a predetermined amount of the material 2 is accommodated between the extending side wall of the cylinder 8 in the constant supply means and the upper surface of the piston 9, and the cylinder A predetermined amount of material 2 accommodated in 8 is pushed onto chute 14 as piston 9 rises.

A predetermined amount of material 2 pushed onto the chute 14 falls along the chute 14 and comes into contact with the direction changing roller 19.

The direction changing roller 19 rotates in the direction of the arrow (counterclockwise) and has a screw thread portion 2 on the outer peripheral surface in the longitudinal direction.
0 is formed to protrude spirally in the screw-saving direction, so that a predetermined amount of the material 2 that has come into contact with the direction changing roller 19 comes into contact with the direction changing roller 19 by the feeding action of the screw thread part 20. The end of the vibrating conveyor 15 is swung toward the rear side of the vibrating conveyor 15, turned sideways, and accommodated in the V-groove 16 of the vibrating conveyor 15;
Due to the vibration effect, the material is transported to a predetermined position relative to a pushing device such as an air cylinder or a press device at the processing site.

Note that when the direction conversion roller 19 is rotated in the opposite direction to the arrow, that is, clockwise, the inward conversion roller 19
The end portion of the material 2 that has come into contact with the vibration conveyor 15 is swung toward the front side of the vibration conveyor 15, and the direction of the material 2 is also changed laterally, and the material 2 is accommodated along the inside of the groove 16 of the vibration conveyor 15.

Further, when the spiral winding direction of the screw thread portion 20 on the outer circumferential surface of the direction conversion roller 19 is provided in the left-hand thread direction, contrary to the above, the direction conversion roller 19
Due to the counterclockwise rotation of the material 2, the end portion of the material 2 that has come into contact with the direction changing roller 19 is swung toward the front side of the vibrating conveyor 15, and the direction is changed sideways, and the direction changing roller 190 is rotated clockwise. The end portions are swung toward the rear side of the vibrating conveyor 15, turned laterally, and accommodated along the V-grooves 16 of the vibrating conveyor 15, respectively.

The vibrating conveyor 15 is formed with a V-groove 16 that is a material storage path with a width that accommodates a single material 2, and normally a predetermined amount of material 2 is conveyed by the direction changing action of the direction changing roller 19.
The materials 2 are transported by the vibrating conveyor 15 in a line along the groove 16, but sometimes some of the materials 2 are transported in an upright state rather than lying down, or some of the materials 2 It is also possible that the materials 2 are transported in an irregularly lined state, such as when the materials 2 are transported in an overlapping state riding on other materials 2, and in that case, the vibration conveyor 15
This state is released by the stepped portion 17 and the baffle plate 18.

That is, when a part of the material 2 is conveyed in an upright state and reaches the step 17, the upper end of the material 2 contacts the baffle plate 18 and is tilted and falls along the step 17, causing vibrations. It is accommodated in the groove 16 of the conveyor 15 in a lying state along the groove.

In addition, when a part of the material 2 is conveyed in an overlapping state on top of another material 2, the upper material 2 is transported by the baffle plate 18.
The material 2 on the lower side falls along the step 17, and after the lower material 2 falls, the material 2 on the upper side falls along the step 17 and similarly falls on the vibrating conveyor 15. It is accommodated in the V-groove 16 in a lying position along the V-groove 16.

FIG. 3 shows another embodiment of the quantitative supply means, which is composed of a cylinder and a piston as in the case of FIG. 1, but unlike the case of FIG. 1, the cylinder 8' is connected to the hopper bottom plate 5. A piston 9' is disposed perpendicularly to the bottom of the hopper at the front end of the cylinder 8', and the upper surface of the piston 9', which reciprocates within the cylinder 8', is tilted downward at an angle of approximately 45° toward the lower part of the vibrating conveyor 15.
This is a sloped surface.

In this case, the piston 9' moves vertically up and down inside the cylinder 8', but the upper surface of the piston 9' is inclined downward at an angle of about 45 degrees toward the vibrating conveyor 15. Therefore, a predetermined amount of material 2 contained in the cylinder 8' is pushed out from the hopper bottom plate 5 onto the chute 14 as the piston 9' rises.

Also, FIG. 4 shows another embodiment of the quantitative supply means, and unlike the cases of FIGS. 1 and 3, it is not based on a cylinder and a piston, but is based on the rotating operation of a rotary plate. be.

That is, the hook-shaped rotary plate 2 has a downward arc-shaped material stopper plate 21 on the hopper bottom side at the front of the hopper bottom plate 5.
2, and the rotary plate 22 is rotated between the hopper bottom plate 5 and the chute 14 using an air cylinder or a hydraulic cylinder 23.

In this case, when the rond of the cylinder 23 is extended and the rotating plate 22 is at the position shown by the solid line in FIG.
When the rond of the cylinder 22 is shortened, the rotating plate 22 becomes the fourth
It rotates counterclockwise as shown by the imaginary line in the figure, and accordingly, a predetermined amount of material 2 stored in the rotary plate 22 is delivered onto the chute 14.

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.

Then, when the cylinder 23 is extended again, the rotary plate 22 rotates clockwise from the position shown by the imaginary line in FIG. 4 to the position shown by the solid line, and this operation is repeated.

In the above embodiment, the reciprocating sliding operation of the pistons 9, 9' in the quantitative supply means is performed by a pulley and a crankshaft connected to a motor, but there is no need to limit it to this, and for example, a reversible motor can be used. A rack attached to the lower side of the piston may be engaged with a pinion connected to the piston, or a pressure fluid such as an air cylinder or a hydraulic cylinder may be used.

Furthermore, although the reverse rotation operation of the rotary plate 22 in the quantitative supply means is shown to be performed by an air cylinder or a hydraulic cylinder 23, there is no need to limit it to this, and a pulley connected to a motor and a crankshaft are used to rotate the rotary plate 22. Alternatively, a pinion and rack connected to a reversible motor may be used.

Further, the relationship between the quantitative supply means and the hopper is shown in which the hopper bottom plate 5 and the piston 9 are arranged separately, but there is no need to limit it to this. For example, one end of the hopper bottom plate 5 is connected to the hopper The other end of the hopper may be pivotally attached to the inner wall of the hopper 1 so that the hopper bottom plate 5 moves up and down as the piston moves up and down. It is sufficient that the hopper is disposed between the hopper and the conveying means so that a predetermined amount of the liquid can be supplied to the conveyor serving as the conveying means.

As described above, the present invention provides a material transport device that stores a large number of materials such as steel materials input from a hopper in a transport means and transports them to a predetermined location via the transport means. A quantitative supply means such as a cylinder and a piston or a rotary plate is provided to supply a predetermined amount of a large number of materials input from a hopper to a conveying means, and the conveying means is arranged in a direction perpendicular to the direction in which the materials are supplied by the quantitative supply means. At the same time, above the end of the conveying means on the opposite side to the quantitative supply means, a direction changing roller is conveyed, which has a screw thread portion spirally protruding from the outer peripheral surface in the longitudinal direction and rotates counterclockwise or clockwise. Since it is arranged along the longitudinal direction of the means, a large number of materials are not supplied to the conveying means at once unlike when materials are directly supplied from a hopper to the conveying means, and the materials are automatically supplied by a predetermined amount, that is, to a certain extent. 1 and 1
The axis of the screw thread portion 20 on the outer circumferential surface of the direction changing roller 19 Due to the feeding action along the direction,
Depending on the spiral winding direction of the screw thread portion 20 and the counterclockwise or clockwise rotation direction of the direction changing roller 19, the material that has come into contact with the direction changing roller 19 is
The end portion thereof is swung along the longitudinal direction of the direction changing roller 19, that is, toward the rear side or the front side of the conveying means, and lies in a lying state within the conveying means, and the direction is changed. They are arranged and housed in a row, respectively.

Therefore, there is no need to manually or using other equipment to line up the materials in a line and send them to the fixed quantity supply means, but simply to randomly feed the materials from the hopper. It is possible to reliably store the materials in a line along the longitudinal direction, and in addition, it is not necessary to supply the materials to the conveying means one by one using the quantitative supply means, but rather to supply them in a certain amount at a time. This makes the material supply work efficient and labor-saving, as well as being economical.

Since the material is fed by the reciprocating movement of the piston or the rotating operation of the rotary plate, there is no need to increase the size of the mechanism depending on the length of the material, and the structure is simple and compact. The price can be made as low as possible.
