  The transport surface (1) is a surface on which the object to be transported is transported along the surface, and is formed so as to be at a high position from one end to the other end. To a horizontal plane (2) formed in a predetermined length range, a curved surface (13) formed into a curved surface having a constant radius continuously with the terminal portion of the horizontal plane (2), and the curved surface (13) A vertical surface (14) formed perpendicularly to the upper end of the upper surface and a curved upper surface (15) formed in an upward semicircular arc shape continuously to the upper end of the vertical surface (14). Has been.

The length of the horizontal surface (2) formed on the transport surface (1) is not particularly limited, but is at least a quarter or more, more preferably 3 minutes, with respect to the overall horizontal length of the transport surface (1). The length is one or more.
In the magnet conveyor according to the present invention, the horizontal surface (2) having a predetermined length is formed on the transport surface (1) as described above, so that the object to be transported can be supplied and transported directly to the horizontal surface (2). Thus, a relatively large amount of objects to be conveyed can be supplied at a time and efficiently conveyed.

These endless tracks (5 ) Continuously moves at a position slightly below the conveying surface (1) as the upper and lower rotating bodies (3) and (4) rotate.
A sprocket can be used for the rotating bodies (3) and (4), and a chain can be used for the endless track.

In addition, a rotating body (31) is disposed at a position below the upper rotating body (3), and a rotating body (32) is also disposed between the rotating body (31) and the lower rotating body (4). The tension of the endless track is adjusted by winding the endless track (5) around the vertically rotating body via these rotating bodies.
Further, the connecting shaft (33) for connecting the left and right rotating bodies constituting the upper rotating body (3) is connected to the rotating shaft of the motor (6), and the left and right rotating bodies are integrally formed by driving the motor (6). It is configured to rotate.

Between the left and right endless tracks (5) respectively wound around the left and right rotating bodies, connecting rods (7) are provided at predetermined intervals along the endless track length direction. It is provided so that a track | orbit may be connected, and the permanent magnet (8) is attached to these connection rods (7), respectively.
The number of magnets (8) attached to the connecting rod (7) is three in the illustrated example, but is not limited to this, and the number is increased or decreased according to the width of the transport surface (1). Moreover, it is good also as a structure which provides one magnet over the full length of a connecting rod (7).

A cylindrical drum (9) is externally fitted to a connecting shaft (33) that connects the left and right rotating bodies in the upper rotating body (3).
FIG. 4 is a front view of the drum (9), and FIG. 5 is a view showing the upper rotating body (3) and the endless track (5) in the sectional view taken along the line AA of FIG. In FIG. 5, the rotating body (3) shows only the tooth pitch circle by a one-dot chain line.
The left and right end portions of the drum (9) are externally fitted to a connecting shaft (33) between the left and right rotating bodies (3), and rotate together with the rotating body (3).
The drum (9) is composed of two semi-cylindrical members (91) and (92) obtained by dividing the cylinder into two in the circumferential direction, and these two semi-cylindrical members (91) and (92) are bolted (10). The cylindrical drum (9) is formed by connecting.
In the present invention, the drum (9) needs to be divided into at least two, but the number of divisions is not limited to two, and can be divided into three or more. It is.

The two semi-cylindrical members (91) and (92) are formed with magnet attachment portions (11) for attaching the auxiliary magnets (12) to the respective circumferential center positions.
The magnet mounting portion (11) has a magnet (8) attached to an endless track (5) wound around the auxiliary magnet (12) and the rotating body (3) at a distance from the center of the connecting shaft (33). ) And the semi-cylindrical member so as to be substantially the same.
In addition, when a drum (9) is divided | segmented into three or more members, it is good to provide a magnet attachment part (11) in each member, and to attach an auxiliary magnet (12).
As shown in FIG. 4, the magnet attachment portion (11) is formed over the entire length in the width direction of the drum (9), and a plurality (three in the illustrated example) of auxiliary magnets (12) are attached at equal intervals. .

In this auxiliary magnet (12), the object to be transported which has been transported along the surface of the transport surface (1) by the magnetic force of the magnet (8) attached to the endless track (5) is transferred from the vertical surface (14). When moving to the upper end curved surface (15), it is provided in order to assist the magnetic force of the magnet (8) and prevent the conveyed object from falling.
The magnet (8) and the auxiliary magnet (12) are displaced from each other in the circumferential direction of the rotating body and the drum so that the conveyed object can smoothly transition from the vertical surface (14) to the upper curved surface (15). In the position.

As described above, in order to reliably transfer the object to be conveyed that has been conveyed along the surface of the conveying surface (1) from the vertical surface (14) to the upper curved surface (15), the magnet (8) The positional relationship with the auxiliary magnet (12) becomes important. For example, if the circumferential interval between the magnet (8) and the auxiliary magnet (12) is large, even if the auxiliary magnet (12) is provided, the magnetic force cannot sufficiently assist the magnetic force of the magnet (8) and is covered. The conveyed product will fall.
In the present invention, the drum (9) is formed by combining a plurality of members divided in the circumferential direction so as to be separable, and the auxiliary magnet (12) is attached to each member. The direction position can be easily and freely set, the positional relationship between the magnet (8) and the auxiliary magnet (12) can always be set to an appropriate position, and the transported object can be reliably prevented from falling. It becomes possible.

Hereinafter, an operation of the magnet conveyor (100) according to the present invention having the above-described configuration will be described.
First, a metal object discharged from a machine tool such as a pressing device or a shearing device, or an object to be conveyed made of metal parts such as a nail or a screw, is first supplied to one end (starting end) of the conveying surface (1). At this time, since the horizontal surface (2) is formed within a predetermined length from one end of the transport surface (1), a relatively large number of objects to be transported can be supplied onto the transport surface (1) at a time. it can.

  The object to be transported supplied on the horizontal surface (2) of the transport surface (1) has an endless track (5) formed by the rotation of the rotating bodies (3) and (4) as the motor (6) is driven. By moving the lower position of (1) along the transport surface, the magnet (8) is subjected to the magnetic force and is transported along the transport surface while being attracted onto the transport surface (1).

As the magnet (8) moves, the object to be conveyed reaches the upper curved surface (15) from the curved surface (13) through the vertical surface (14) as shown in FIG.
When the transferred object moves to the upper curved surface (15) via the vertical surface (14), the magnetic force of the auxiliary magnet (12) attached to the drum (9) assists the magnetic force of the magnet (8). Thus, the object to be conveyed is reliably conveyed from the vertical surface (14) to the upper end curved surface (15) without falling.
Then, the conveyed object that has reached the upper curved surface (15) is released from the action of magnetic force by moving to the shooter (18), and falls to a predetermined position along the shooter (18).

Figure 7 is a schematic side view of a magnet conveyor of the second reference embodiment according to the present invention.
The magnet conveyor (200) of the second reference form is different from the magnet conveyor (100) of the first reference form described above in that a large number of objects to be conveyed are loosened at one end (starting end) of the carrying surface (1). However, the unwinding supply mechanism for supplying on a horizontal surface is provided.
FIG. 8 is a front view of the unwinding supply mechanism, and the unwinding supply mechanism is disposed on the horizontal surface (2) and is provided inside the hopper (19) and the hopper (19) to which the object to be conveyed is supplied. The loosening rod (20) has a substantially elliptical cross section and reciprocates around the axis, and the driving mechanism (21) drives the loosening rod (20) back and forth around the axis.

9 is a front view of the loosening bar (20), FIG. 10 is a plan view of the loosening bar (20), FIG. 11 is a view in the direction of arrow A in FIG. 10, and FIG. 12 is a view in the direction of arrow B in FIG.
The loosening rod (20) is formed by flattening a cylindrical pipe. As shown in the drawing, the base end portion has a circular cross section, but it is a substantially oval shape that gradually becomes flat from the midway portion to the distal end portion. It has a cross section of a pillar. However, in this invention, it is good also as a stick | rod which has the cross section of a substantially elliptic cylinder over the full length direction.
The tip of the loosening bar (20) is preferably rounded as shown by a broken line in order to prevent the conveyed object from being damaged.
And the connection hole (22) with a keyway for connecting with a drive mechanism (21) is provided in the base end part of the loosening rod (20).

The drive mechanism (21) is a mechanism for reciprocatingly driving the above-described loosening rod (20) within a range of half rotation or less around the axis, and is provided at an external position in the vicinity of the hopper (19).
The drive mechanism (21) includes a motor (22), a first rotating plate (23) that is connected to a rotation shaft of the motor (22) and rotates as the motor rotates, and a loosening rod (20). It comprises a second rotating plate (24) connected to the center and a connecting rod (25) connecting these first and second rotating plates.

The rotating shaft of the motor (24) is directly connected to the center of the first rotating plate (23) in the illustrated example, but may be indirectly connected via a track or the like.
The second rotating plate (24) is arranged above the first rotating plate (23) so that the center thereof is at the same height as the center of the loosening rod (20). (24) and the loosening bar (20) are connected by a cylindrical rotating bar (27) rotatably supported by a pair of bearings (26).
That is, one end of the rotating rod (27) is inserted and fixed together with a key into a connecting hole (22) provided at the proximal end of the loosening rod (20), and the other end is fixed to the second rotating plate (24). ) Is inserted into and fixed to the center hole (28), whereby the rotation of the second rotating plate (24) is transmitted to the unwinding rod (20) via the rotating rod (27). Yes.

The connecting rod (25) is pivotally attached so as to connect these rotary plates to a position eccentric from the rotation center of one surface of the first rotary plate (23) and the second rotary plate (24). Has been.
More specifically, a joint portion (29) having a cylindrical portion is provided at both ends of the connecting rod (25), and pins (30) are provided on the surfaces at positions eccentric from the centers of the rotary plates (23) and (24). ) And the pins (30) are inserted into the holes of the joint portion (29), so that both end portions of the connecting rod (25) are freely rotatable at the connecting portions with the rotating plates (23) and (24). It has become.
Here, the distance between the center of the second rotating plate (24) and the pin (30) is set longer than the distance between the center of the first rotating plate (23) and the pin (30), In the illustrated example, this is achieved by making the radius of the disk constituting the second rotating plate (24) larger than the radius of the disk constituting the first rotating plate (23).

Hereinafter, the operation of the drive mechanism (21) will be described.
When the motor (22) rotates in one direction, the first rotating plate (23) connected to the rotating shaft of the motor (22) rotates in one direction.
Assuming that FIG. 13 is in an initial state, when the first rotating plate (23) rotates, the second rotating plate (24) connected to the first rotating plate (23) by the connecting rod (25) is shown in FIG. As shown in FIG. 14, first, it rotates in the same direction as the first rotating plate (23) (right direction in the illustrated example).
When this rotation further proceeds, the pin (30) of the first rotating plate (23) reaches the upper end as shown in FIG. 16, but the second has a larger radius than the first rotating plate (23). In the rotating plate (24), the pin (30) does not reach the upper end.

Therefore, when the first rotating plate (23) continues to rotate, the distance between the pins (30) of the two rotating plates is fixed by the connecting rod (25), so the second rotating plate (24). Cannot continue to rotate in the same direction as the first rotating plate (23), but rotates in the opposite direction (left direction) as shown in FIG.
The reverse rotation of the second rotating plate (24) continues until the pin (30) of the first rotating plate (23) reaches the lower end position, but as shown in FIG. 13, the first rotating plate (23) When the first pin (30) reaches the lower end position, the pin (30) does not reach the lower end in the second rotary plate (24) having a radius larger than that of the first rotary plate (23). The second rotating plate (24) rotates again in the original rotating direction (right direction).

By the above-described series of operations, the second rotary plate (24) reciprocates around the axis in a range of half or less, and the unwinding rod (20) also reciprocates around the axis in a range of less than half a revolution. Come to drive.
However, in the present invention, the configuration of the drive mechanism (21) is not particularly limited as long as it can reciprocate the loosening rod (20) around the axis, and known cams, links, cranks, gears, and the like. It is possible to combine different mechanism elements into different structures.

  The unwinding rod (20) is reciprocated within a half rotation or less when the unwinding rod (20) rotates in one direction beyond the half rotation and the object to be conveyed is placed on the opposite side across the unwinding rod (20). This is because the transported object is hindered from being smoothly discharged from the hopper (19).

Moreover, the following effect | action is exhibited because the loosening rod (20) has the cross section of an elliptic cylinder.
First, since there is a substantially flat portion having a large surface area, a very large stirring effect can be obtained as compared with a circular section. And since there is no corner, a long thing flows smoothly along the surface of the loosening rod (20) without being caught, and thereby smooth stirring is performed.

Hereinafter, operation | movement of the magnet conveyor (200) of the 2nd reference form provided with the above-mentioned loosening supply mechanism is demonstrated.
When the object to be conveyed is supplied into the hopper (19), the loosening rod (20) is reciprocated around the axis within a half rotation or less in accordance with the operation of the drive mechanism (5) in the hopper (19). As a result, the object to be transported falls and is supplied onto the horizontal surface (2) of the transport surface (1) in a loosened state.
When the object to be conveyed supplied to the magnet conveyor (200) of the second reference form is a long object such as a nail or a screw, the objects to be conveyed supplied to the conveying surface (1) are entangled with each other so that the conveyance is smooth. However, since such a loosening supply mechanism is provided, the objects to be conveyed are prevented from being entangled with each other, and a smooth conveyance state can be maintained at all times.
Note that the object to be transported dropped on the transport surface (1) is moved along the transport surface by the same action as that of the magnet conveyor (100) of the first reference embodiment not provided with the above-described loosening supply mechanism. Will be transported.

Next, the magnet conveyor (300) of the 3rd reference form is explained.
Figure 17 is a schematic side view of a magnet conveyor third reference embodiment according to the present invention.
The basic configuration of the magnet conveyor (300) of the third reference form is the same as the magnet conveyors (100 and 200) of the first and second reference forms described above, but the transport surface (1) for transporting the object to be transported. It has a feature in the shape.

  The transport surface (1) is a surface on which the object to be transported is transported along the surface, the horizontal surface (2) formed in a predetermined length range from one end to the other end, and the horizontal surface (2 ) And a curved surface (13) formed in an arc shape having a constant radius so as to gradually become higher, and a vertical surface (14) formed perpendicular to the upper end of the curved surface (13). ) And an upper end curved surface (15) formed in an upward semicircular arc shape continuously with the upper end portion of the vertical surface (14).

The length of the horizontal surface (2) formed on the transport surface (1) is not particularly limited, but is preferably at least a quarter or more of the overall length (L) in the horizontal direction of the transport surface (1), more preferably. The length is one third or more.
In the magnet conveyor according to the present invention, the horizontal surface (2) having a predetermined length is formed on the transport surface (1) as described above, so that the object to be transported can be supplied and transported directly to the horizontal surface (2). Thus, a relatively large amount of objects to be conveyed can be supplied at a time and efficiently conveyed.

The curved surface (13) formed on the transport surface (1) is an arcuate surface having a constant radius as described above.
The central angle of the arc forming the curved surface (1) is 90 °, and the curved surface (1) is formed by the arc of the lower right quarter of the circle.
The radius (R) of the arc is not particularly limited, and can be set as appropriate according to conditions such as the height at which the object is transported. Preferably, the total length (L) (horizontal length of the apparatus) )), More preferably a certain ratio or more with respect to both the total length (L) and the total height (H) (vertical length) of the apparatus. This constant ratio is 40% or more, preferably 45% or more, and more preferably 50% or more. Specific values of R include, for example, about 300 to 500 mm.
In this way, the curved surface (13) having an arc shape with a constant radius is formed on the conveying surface (1), so that even when a large amount of objects to be conveyed is supplied to the horizontal surface (2) at a time, the curved surface (13) is curved. Since the object to be conveyed that cannot be absorbed by the magnetic force when being conveyed upward along the surface (13) slides down without being able to ascend the curved surface (13), the object to be conveyed that has been solidified by being supplied in large quantities at once. Objects are unraveled and transported smoothly.

Hereinafter, a description of the operation of the magnet conveyor (300) of the third reference embodiment according to the present invention having the above structure.
Conveyed objects made of metal scrap discharged from a machine tool such as a press device or a shearing device, or metal parts such as nails and screws are supplied into the hopper (19), and are conveyed from the bottom of the hopper (19). It is supplied to one end (starting end) of (1).
At this time, since the horizontal surface (2) is formed in a predetermined length range from one end of the transport surface (1), a relatively large number of objects to be transported can be supplied onto the transport surface (1) at a time. .

The object to be transported supplied on the horizontal surface (2) of the transport surface (1) has an endless track (5) formed by the rotation of the rotating bodies (3) and (4) as the motor (6) is driven. By moving the lower position of (1) along the transport surface, the magnet (8) is subjected to the magnetic force and is transported along the transport surface while being attracted onto the transport surface (1).
And a to-be-conveyed object is conveyed from a horizontal surface (2) to a curved surface (13) with a motion of a magnet (8), and raises along a curved surface (13).
At this time, the object to be conveyed that cannot be adsorbed by the magnetic force cannot move up the curved surface (13) and slides down along the curved surface, so that the object to be conveyed that has been solidified by being supplied in large quantities to the horizontal surface (2) at a time. Things are loosened.

  As shown in FIG. 18, the conveyed object that has risen along the curved surface (13) reaches the upper curved surface from the curved surface (13) through the vertical surface (14) to the upper curved surface (15). The conveyed object is released from the action of magnetic force by moving to the shooter (18), and falls to a predetermined position along the shooter (18).

FIG. 19 is a schematic side view showing the magnet conveyor according to the embodiment of the present invention .
The magnet conveyor (400) of the present embodiment is different from the magnet conveyors (100, 200 and 300) of the first to third reference embodiments described above in the shape of the transport surface (1).
Specifically, the conveyance surface (1) has a horizontal surface (2), a curved surface (13), and a vertical surface (14) in order from one end portion (start end portion) in that the magnet conveyor (300) of the third reference form. The upper end curved surface (15) is not provided, but instead the opposite end (end portion) of the conveying surface (1) is opposed to the horizontal plane (2) within a predetermined length range. A downward horizontal surface (411) formed, and an arc-shaped second curved surface (412) formed so as to connect the start end portion of the downward horizontal surface (411) and the end portion of the vertical surface (14). The entire conveyance surface has a substantially U-shape.

Also in the magnet conveyor (400) of this embodiment, the configuration in which the magnet moves along the transport surface (1) below the transport surface (1) is the magnet conveyor (100, 100) of the first, second, or third reference form. 200 or 300), and along with the movement of the magnet, the object to be conveyed moves on the surface of the substantially U-shaped conveying surface (1).
The length of the horizontal plane (1) and the radius of the arc constituting the curved surface (13) are preferably set similarly to the conveyors (100, 200 and 300) of the first to third reference embodiments.
Therefore, also in the magnet conveyor (400) of the present embodiment , the horizontal plane (2) is formed in a predetermined length range from one end of the conveyance surface (1), so that a relatively large number of objects to be conveyed can be transferred at a time. Since the object to be conveyed that cannot be attracted by the magnetic force can slide on the curved surface (13) without being lifted up, the object to be solidified can be supplied onto the curved surface (13). ) And is smoothly transported.

In addition, in order to move the magnet along the curvature of the second curved surface (412), as shown in the figure, a curved radius that is curved in the same manner as the curved surface (412) is formed above the second curved surface (412). A plate-shaped guide member (40) is provided.
The guide member (40) is made of a resin (for example, polyamide) having excellent wear resistance, and the endless raceway (5) extends along the upper surface of the guide member (40) as shown in FIG. By doing so, the endless track (5) is arranged along the curve of the second curved surface (412).
At this time, the distance (d1) between the second curved surface (412) and the endless track (5) is the distance (d2) between the downward horizontal surface (411) and the vertical surface (14) and the endless track (5). The position of the guide member (40) is set so as to be equal to the distance between and. This is because when d1> d2, the force with which the magnet attracts the object to be conveyed becomes weak at the second curved surface (412), and the object to be conveyed may fall.

In the magnet conveyor (400) of this embodiment , since the conveyance surface (1) is provided with the second curved surface (412) and the downward horizontal surface (411), the object to be conveyed supplied to the hopper (19) is After being sequentially transported from the horizontal surface (2) to the curved surface (13) and the vertical surface (14), the second curved surface (412) is conveyed along the downward horizontal surface (411), and ends at the downward horizontal surface (411). When it reaches the part, it is released from the magnetic force, falls downward, and is supplied to a predetermined container (410) or the like.
Therefore, according to the apparatus (400) of this embodiment , it becomes possible to supply a to-be-conveyed object almost directly above a supply point similarly to the conventional vertical conveyor.

Note that the method for releasing the object to be conveyed along the conveying surface (1) from the magnetic force reduces the magnetic force acting on the object to be conveyed by increasing the distance from the conveying surface to the magnet at the release point. This may be the same for the conveyors (100, 200 and 300) of the first to third reference embodiments described above.

In the present invention, the hopper (19) disposed above the horizontal surface (2) of one end (starting end) of the transport surface (1) is used to loosen the object to be transported supplied inside the hopper. A loosening mechanism is preferably provided (see FIG. 7).
This unraveling mechanism can utilize the unraveling mechanism employed in the magnet conveyor (200) of the second reference form described above.

The magnet conveyor (500) of the 4th reference form concerning the present invention is explained.
20 is an external perspective view showing a magnet conveyor according to the fourth embodiment of the present invention, FIG. 21 is a schematic side view of the magnet conveyor according to the fourth embodiment of the present invention, and FIG. It is a figure which shows the internal structure of A part. Note that, in FIG. 22, in order to make the drawing easy to see, only the midway portion of the endless track is illustrated, and the upper and lower portions of the endless track are indicated by alternate long and short dash lines.
The basic configuration of the magnet conveyor (500) of the fourth reference embodiment according to the present invention is the same as that of the magnet conveyor (400) of the above embodiment, and the description thereof is omitted. The magnet conveyor (500) of the fourth reference embodiment is different from the configurations of the first to third reference embodiments and the magnet conveyor of the above embodiment in the arrangement of the magnet (8) of the holding body (7), and It is that the conveyance amount adjustment material provided in each place of a conveyance surface (1) is provided.

The magnet (8) attached to the holding body (7) is preferably provided so as to be detachably attached to the holding body (7). The example shown in FIG. 22 shows an example in which three magnets are provided, and FIG. 23 shows an example of attaching magnets, in which (a) four pieces are arranged, (b) two pieces are arranged, and (c) An example in which one is arranged is shown.
For example, in the arrangement of each magnet as shown in FIG. 23, when the magnet conveyor (500) of the fourth reference embodiment is actually used, as shown in FIG. M) is attracted and transported. In FIG. 24, only one object (M) is depicted for each magnet, but the number of objects (M) to be attracted by the magnetic force is not limited. In the drawings shown below, the symbol (M) indicates a conveyed object.
Since the object to be conveyed (M) is conveyed by the attractive force of the magnet (8), the object to be conveyed (M) is conveyed only to the place where the magnet (8) is arranged.

The arrangement of the magnet (8) of the holding body (7) included in the magnet conveyor (500) of the fourth reference form is arranged on both sides arranged along the length direction of the endless endless track (5). It is provided so as to be different from the arrangement of the magnet (8) of the holding body (7) (see FIG. 25).
The magnets (8) provided in the holding body (7) are arranged so that the holding bodies (7) arranged on both sides of the holding body (7) provided endlessly along the endless track (5). ) Are provided so as to be different from the arrangement of the magnets (8) included in.
The arrangement of the magnets (8) of the plurality of holding bodies (7) arranged endlessly along the endless track (5) is different from the arrangement of the magnets of the adjacent holding bodies. 7) Since the number of objects (M) to be conveyed is different, when the holder (7) conveys the object to be conveyed (M), the object to be conveyed (M) is solidified and conveyed in an overlapping manner. This is because it is possible to prevent this, and in the transport amount adjusting material to be described later, the objects to be transported (M) can be reliably arranged in a certain direction.

  The arrangement of the magnet (8) included in the holding body (7) is not particularly limited as long as the arrangement is different from the arrangement of the magnet (8) of the holding body (7) on both sides as described above. The arrangement of the magnet (8) of the holding body (7) is, for example, the entire width in the longitudinal direction of the holding body (7) in order to break up the mass of the mass of the object to be conveyed (M) and convey it as a small mass. The magnet (8) is disposed at an appropriate interval (for example, 1 to 3) in the longitudinal width of the holding body (7) in order to individually convey the object (M) to be disposed or the magnet (8). In order to convey the object to be conveyed (M) in the vicinity of one of the left and right side plates (16) and the width in the longitudinal direction of the holder (7). The arrangement | positioning etc. which are provided in the vicinity of either side plate (16) of this are considered. And it is possible to employ | adopt the structure which arrange | positions sequentially the holding body (7) by which the magnet (8) is arrange | positioned in this way in the length direction of an endless track (5).

The arrangement of the magnets (8) is not particularly limited. For example, as shown in FIG. 25, the holder (7) of the first stage N1 has four magnets (8) arranged, and the second stage. Two N2 holding bodies (7) are arranged with an interval corresponding to one magnet 9, and one third holding body (7) of the stage N3 is arranged at an interval of the magnet (8) of the stage N2. Two holders (7) of the fourth stage N4 are arranged side by side from the left end, and magnets (8) are arranged, and two holders (7) of the fifth stage N5 are arranged side by side from the right end (8) ) Is arranged.
Although arrangement | positioning of the magnet (8) as mentioned above is not specifically limited, The peak of a to-be-conveyed object (M) can be destroyed with the holding body (7) of the step N1. Next, a small amount can be conveyed and quantified by the holder (7) of the stage N2. Next, the carrier (7) of the stage N3 can make it easy for the conveyance amount adjusting material to arrange the objects to be conveyed (M). The transported object (M) disposed on the front right side of the transport surface (1) is transported by the holding body (7) of the stage N4, and the transported object ( M) can be transported.
The transport surface (1) is disposed in parallel with the width direction of the transport surface (1) and over the entire width of the transport surface (1), and is disposed at a predetermined distance d from the transport surface (1). One or a plurality of conveyance amount adjusting materials are provided.

The predetermined interval (d) from the conveyance surface (1) on which the conveyance amount adjusting material is provided is not particularly limited, but is conveyed by the object (M) passing through the predetermined interval (d). Since the amount can be adjusted, the predetermined amount (d) may be adjusted by appropriately determining the transport amount of the object (M) desired by the user.
As shown in FIG. 26, the conveyance amount adjusting material includes a holding member (B) arranged parallel to the width of the conveyance surface (1) and substantially perpendicular to the conveyance surface (1), and a holding member (B ) From the flexible member (A) projecting toward the conveying surface (1). FIG. 7A is a perspective view showing the carry amount adjusting material, and FIG. 7B is a perspective view of the carry amount adjusting material provided with a protective member to be described later.
Since the flexible member (A) of the transport amount adjusting material (510) contacts the transported object (M), it is damaged even if the transported object (M) contacts the flexible member (A). It is necessary to form the material with no fear, and a flexible material such as urethane rubber is conceivable.

The flexible member (A) is formed in a square shape, and the length of the flexible member (A) in the longitudinal direction is slightly shorter than the distance between the left and right side plates (16). This flexible member (A) is provided with a notch (F) perpendicular to this side at a predetermined interval from one side of the conveying surface (1). The length of the cut (F) and the predetermined interval provided are not particularly limited, and may be appropriately provided according to the object (M) to be conveyed.
Since this flexible member (A) has a plurality of cuts (F), when passing through the conveyance amount adjusting material (510), the flexible member (A) is arranged parallel to the flow of the conveyance surface (1). The conveyed object (M) passes smoothly without receiving a large resistance force. On the other hand, the conveyed object (M) arranged at right angles to the flow of the conveying surface (1) receives a large resistance force from the flexible member (A). In order to decrease, the object to be conveyed (M) rotates on the conveying surface (1) around the point adsorbing to the magnet (8) and moves so as to be parallel to the flow of the conveying surface (1). Will do.

The holding member (B) may be formed so as to be attached to the left and right side plates (16). In the embodiment of the present invention, the holding member (B) is attached to the left and right side plates (16). ), A holding member (B) is provided at the attachment portion (C), and a flexible member (A) is provided so as to project from the holding member (B) toward the conveying surface (1). ing.
The means by which the holding member (B) holds the flexible member (A) is not particularly limited. In FIG. 26, the holding member (B) is screwed using a screw (D).
In addition, although this conveyance amount adjustment material (510) can also be attached so that the opposing side wall may be bridge | crosslinked, you may attach in parallel with the flow direction of a conveyance surface (1) along one side wall (16). Absent.

By providing the transport amount adjusting material (510), the transported object (M) is transported on the transport surface (1) by a magnetic force, so that an extra transported object (M) is generated by the attractive force of the magnet (8). Even in the case of being transported in multiple layers, it is possible to remove the excessively transported object (M) that overlaps reliably, and to act on the transported object (M) so as to face a certain direction.
A plurality of transport amount adjusting materials (510) may be provided along the transport surface (1), but at least in the vicinity of the terminal end of the horizontal surface (2) so as to be substantially perpendicular to the horizontal surface (2). The first transport amount adjusting material (X) or the second transport amount adjusting material (Y) provided so as to be substantially perpendicular to the curved surface (13) is provided in the vicinity of the end surface of the curved surface (13). It is preferable.

By providing this first transport amount adjusting material (X), when a large amount of transported object (M) is supplied and transported from the hopper (6) upstream of the horizontal surface (2) of the transport surface (1). However, the first conveyance amount adjusting material (X) can control the conveyance amount (see FIG. 27). In addition, the 1st conveyance amount adjustment material (X) may be arrange | positioned between a conveyance surface (1) and a horizontal surface (2), and may be provided on a horizontal surface (2).
The distance (d3) from the conveyance surface (1) on which the first conveyance amount adjusting material (X) is provided is maximally bent by the flexible member (A) of the first conveyance amount adjusting material (X). The vertical distance from the transport surface (1) at that time. This distance (d3) regulates the transport amount of the transported object (M) to be transported, and the transported object (M) that can pass the distance (d3) becomes the transport amount. (See FIG. 27B).

By providing the second transport amount adjusting material (Y) in the vicinity of the terminal portion of the curved portion (13), the transported object (M) transported in an overlapping manner uses the weight of the transported object (M). Can be reliably shaken and can act to direct the conveyed object (M) in a certain direction (see FIG. 28).
The distance (d4) from the transport surface (1) on which the second transport amount adjusting material (Y) is provided is maximally bent by the flexible member (A) of the second transport amount adjusting material (Y). The vertical distance from the transport surface (1) at that time. The second transport amount adjusting material (Y) is shaken by limiting the overlapping member of the transported object (M) to be transported by the distance (d4) between the flexible member (A) and the transport surface (1). It is possible to act so that the conveyed object (M) is directed in a certain direction (see FIG. 28B).
By this swinging off, the extra transported object (M) slides down the curved surface (13), and the transport amount by which the transported object (M) is transported can be adjusted with certainty.
A flexible protection member (E) is provided on the upstream side surface of the holding member (B) of the second transport amount adjusting material (Y) (see FIG. 26B). By providing the protective member (E), the object (M) to be conveyed is damaged when the object (M) falling from the vertical surface (14) is received by the second conveyance amount adjusting material (Y). You can receive without.

The transport surface (1) is a vertical surface (14) having a predetermined angle θ so that the third transport amount adjusting material (Z) is inclined downward with respect to the vertical surface (14), and the transport surface (1). ) Is preferably provided at a predetermined interval (d5).
The configuration of the third transport amount adjusting material (Z) is provided in the same manner as the second transport amount adjusting material (Y), and the transport surface (1) provided on the third transport amount adjusting material (Z). (D5) is a vertical distance from the conveyance surface (1) when the flexible member (A) of the third conveyance amount adjusting material (Z) is bent to the maximum.
By providing the third transport amount adjusting material (Z), it is possible to receive an object (M) that falls from the vertical surface (14), and the third transport amount adjusting material (Z) has a predetermined angle θ. By having the inclination, the received object (M) that has been received slides down on the conveyance surface (1) as it is, and can be sent back to the conveyance surface (1) (or the horizontal surface (2)) (FIG. 29). reference).
Further, the third transport amount adjusting material (Z), like the first and second transport amount adjusting materials (X, Y), is configured so that the transported object (M) passing therethrough is in a certain direction. It works by the flexible member (A) that the amount adjusting material (Z) has.

The protective member (E) described above is preferably provided on the downstream surface side of the third transport amount adjusting material (Z). This is because by providing the protection member E, the falling object (M) can be received without being damaged.
The predetermined angle θ of the third transport amount adjusting material Z is provided at 40 to 80 degrees, preferably 50 to 70 degrees, and more preferably 55 to 65 degrees.
The above is the configuration of the magnet conveyor (500) of the fourth reference embodiment of the present invention.

When transporting a thick transport object (M), the predetermined intervals (d3, d4, d5) are widened, and when transporting a thin transport object (M), it is predetermined. The intervals (d1, d2, d3) may be narrowed.
In addition, it is preferable to provide the predetermined space | interval (d) of the conveyance amount adjustment material (510) provided in the magnet conveyor (500) of a 4th reference form so that it may become narrow gradually from the upstream to the downstream. This is because the transport amount can be adjusted by being provided as described above.

  Next, when passing through the first transport amount adjusting material (X), the overlapped transported object (M) is removed and adjusted to a certain transport amount to a small extent (see FIG. 27). At this time, the removed transported object (M) is transported by the holding body (7) in which the next two or one magnet (8) is arranged. Since the arrangement of the magnets different from the (first conveyed) holding body (7) is performed, the object (M) to be conveyed is conveyed in a different arrangement from the previous (first holding body (7)). It will be. That is, quantification is performed so that a predetermined transport amount is transported by thinning the transported object (M) transported by the holder (7).

The transported object (M) that has reached the second transport amount adjusting material (Y) overlaps with the second transport amount adjusting material (Y), which could not be removed by the first transport amount adjusting material (X). The transported object (M) can be removed, and the transported object (M) is directed in a certain direction (direction along the flow of the transport surface (1)) by the resistance force of the flexible member (A). Work on. The transported object (M) that has passed through the second transport amount adjusting material (Y) has approximately one transported object (M) with respect to the magnet (8) of the holding body (7) at this time. Will be.
