The best mode for carrying out the present invention will be described.
1 is an external perspective view showing an example of a magnet conveyor according to the present invention, FIG. 2 is a schematic side view of the magnet conveyor according to the present invention, and FIG. 3 is a diagram showing an internal structure of a portion A in FIG. is there. In FIG. 3, only the middle part of the chain is shown for easy understanding of the drawing, and the upper part and the lower part of the chain are shown by alternate long and short dash lines.
The magnet conveyor (1) according to the present invention is configured to adsorb a material made of a magnetic material such as a metal that can be attracted to a magnet (hereinafter referred to as an object to be transported) to a transport surface (2) by using a magnetic force. It is an apparatus that conveys the object to be conveyed from the upper position to the upper position and further aligns the objects to be conveyed. For example, the object to be conveyed is most effective in aligning a deformed member having a head portion and a body portion such as a screw or a pin.

The magnet conveyor (1) is a pair of left and right rotating surfaces disposed below the left and right ends of the conveying surface (2) in the width direction of the conveying surface (2) where the object to be conveyed is conveyed along the surface. A sprocket (3, 4), a pair of left and right chains (5) wound around the sprocket (3, 4) and moving along the transport surface (2) at a position below the transport surface (2), The left and right chains (5) are provided with holding bodies (9) attached at predetermined intervals along the length direction of the chain (5).
The transport surface (2) is a surface on which the object to be transported is transported along the surface, and a horizontal surface (21) formed in a predetermined length range from one end to the other end, and a horizontal surface (21). A curved surface (22) formed in an arc shape with a constant radius so as to gradually become a higher position from a terminal portion of the curved surface, and a vertical surface (23) formed perpendicular to the upper end portion of the curved surface (22). And is formed from.
The length of the horizontal surface (21) formed on the transport surface (2) is not particularly limited, but is at least a quarter or more, more preferably 3 minutes, with respect to the overall horizontal length L of the transport surface (2). The length is one or more.
In the magnet conveyor (1) according to the present invention, since the horizontal surface (21) having a predetermined length is formed on the transport surface (2) as described above, the object to be transported is supplied directly to the horizontal surface (21). It becomes possible to convey, and a relatively large amount of objects to be conveyed can be supplied at a time and efficiently conveyed.

The curved surface (22) formed on the transport surface (2) is an arc-shaped surface having a constant radius as described above.
The central angle of the arc forming the curved surface (2) is approximately 90 °, and the curved surface (22) is formed by the arc of the lower right quarter of the circle. The central angle is not particularly limited, but is preferably approximately 90 ° because the transport surface (2) has a vertical surface (23) described later.
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 radius R of the apparatus is relative to the total length L (horizontal length) of the apparatus. More than a certain ratio, more preferably more than a certain ratio for 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 (22) having an arc shape with a constant radius is formed on the conveying surface (2), so that even when a large amount of objects to be conveyed is supplied to the horizontal surface (21) at a time, the curved surface (22) is curved. Since the object to be conveyed that cannot be adsorbed by the magnetic force when being moved upward along the surface (22) cannot slide up the curved surface (22), it slides down and is solidified by being supplied in large quantities at a time. The transported object is unraveled and transported smoothly.

Side plates (11) are provided at both left and right ends of the transport surface (2) so as to protrude from the upper surface of the transport surface (2). The side plates (11) are cross-linked with a plurality of conveyance amount adjusting materials to be described later.

Due to the transfer path (25), the object to be conveyed that has reached the upper end of the conveying surface (2) falls to a predetermined location. As this transfer path (25), a shooter may be provided.
In addition, it is preferable that the demagnetizer (26) is provided in this transfer path (25), and the to-be-conveyed object which transfers this transfer path (24) can be demagnetized. By providing the demagnetizer (26), the object to be conveyed conveyed on the conveying surface (2) is magnetized, so that the object to be conveyed can be reliably demagnetized by the demagnetizer (26). It will be possible.
The demagnetizer (26) is not particularly limited as long as it can demagnetize the object to be transported in the transfer passage (25), but a cylindrical demagnetizer provided to cover the transfer passage (25) is preferable. . This is because a magnetic field can be generated by using the cylindrical demagnetizer so as to surround the object to be conveyed in the transfer passage (25).

As shown in FIG. 2, an upper sprocket (3) and a lower sprocket (4) are disposed at the start end (lower end) and the end end (upper end) of the transport surface (2), respectively. (3, 4) is composed of a pair of left and right sprockets arranged side by side in the width direction of the conveying surface (2).
An endless chain (5) is wound around each of the left and right sprockets from the upper sprocket (3) to the lower sprocket (4). These chains (5) are connected to the upper and lower sprockets (3, 4). ) And continuously move slightly below the conveying surface (2).

Further, a sprocket (31) is also disposed below the upper sprocket (3), and a sprocket (32) is also disposed between the sprocket (31) and the lower sprocket (4). The tension of the chain (5) is adjusted by winding the chain (5) around the upper and lower sprockets via the sprocket.

These holding bodies (9) are each provided with one or a plurality of permanent magnets (91).

The magnet (91) attached to the holding body (9) is preferably provided so that it can be detachably attached to the holding body (9). In the example shown in FIG. 3, an example in which three magnets are provided is shown, and FIG. 4 shows an example of attachment of magnets, (a) four are arranged, (b) two are arranged, (c) is An example in which one is arranged is shown.
For example, in the arrangement of the magnets as shown in FIG. 4, when the magnet conveyor (1) is actually used, the object to be conveyed M is attracted and conveyed for each magnet as shown in FIG. Become so. In FIG. 5, only one object to be conveyed M is depicted for each magnet, but the number of objects (M) to be adsorbed 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 (91), the object to be conveyed (M) is conveyed only to the place where the magnet (91) is arranged.
The arrangement of the magnet (91) of the holding body (9) included in the magnet conveyor (1) of the present invention is such that the holding bodies (9) on both sides arranged along the length direction of the endless chain (5). It is provided so as to be different from the arrangement of the magnets (91) of (see FIG. 6).
The magnet (91) provided in the holding body (9) is arranged in the holding body (9) arranged on both sides of the holding body (9) provided endlessly along the chain (5). Provided to be different from the arrangement of the magnet (91).
The arrangement of the magnets (91) of the plurality of holding bodies (9) arranged endlessly along the chain (5) is different from the arrangement of the magnets of the adjacent holding bodies, and each holding body (9) When the number of transported objects (M) to be transported is different, the transported object (M) is prevented from being conveyed in a lump when the holder (9) transports the transported object (M). This is because the object to be conveyed (M) can be reliably arranged in a certain direction in the conveyance amount adjusting material (10) described later.

  The arrangement of the magnet (91) of the holding body (9) is not particularly limited as long as it is different from the arrangement of the magnet (91) of the holding body (9) adjacent to both sides as described above. The arrangement of the magnets (91) of the holding body (9) is, for example, the full width in the longitudinal direction of the holding body (9) in order to break up the piles of the mass of the object to be conveyed (M) and convey them as a small amount of mass The magnet (91) is arranged at an appropriate interval (for example, 1 to 3) in the longitudinal width of the holding body (9) in order to dispose the arrangement of the magnet (91) on the holder and the object (M) to be conveyed individually. In order to convey the object (M) in the vicinity of either the left or right side plate (11), the width of the holder (9) in the longitudinal direction An arrangement or the like provided in the vicinity of either the left or right side plate (11) is conceivable. And it is possible to employ | adopt the structure which arrange | positions sequentially the holding body (9) by which the magnet (91) is arrange | positioned in this way in the length direction of a chain (5).

The arrangement of the magnets (91) is not particularly limited. For example, as shown in FIG. 6, the holding body (9) of the first stage (N1) includes four magnets (91). Two holding bodies (9) of the second stage (N2) are arranged with an interval corresponding to one magnet (9), and the holding bodies (9) of the third stage (N3) are arranged on the stage (N2). One magnet (91) is arranged at intervals of the fourth stage (N4), and two magnets (91) are arranged from the left end to hold the fifth stage (N5). Two magnets (91) are arranged side by side from the right end of the body (9).
The arrangement of the magnet (91) as described above is not particularly limited. For example, the pile of the conveyed object M can be broken by the holder (9) of the first stage (N1). Next, a small amount can be conveyed and quantified by the holder (9) of the stage (N2). Next, the conveyance amount adjusting material (10) can easily arrange the objects to be conveyed (M) by the holding body (9) of the step (N3). The transported object (M) disposed on the front right side of the transport surface (2) is transported by the holder (9) of the step (N4), and is disposed on the front left side by the retainer (9) of the step (N5).

In addition, when the transport surface protector is worn, it is possible to use it for a long time only by replacing the transport surface protector.
In addition, this conveyance surface protection body is stuck and provided over the full length and full width of a conveyance surface (2) using a double-sided tape on the surface.
The above is the configuration of the magnet conveyor (1) of the present invention.

Hereinafter, the operation of the magnet conveyor (1) according to the present invention will be described with reference to the drawings.
FIG. 14 is a diagram showing an operating state of the magnet conveyor according to the present invention.
First, before operating the magnet conveyor (1), a predetermined interval between the first transport amount adjusting material (X), the second transport amount adjusting material (Y), and the third transport amount adjusting material (Z) is set to the object to be transported ( Determine according to M). When transporting a thick transport object M, the predetermined intervals d1, d2, and d3 are widened. When transporting a thin transport object M, the predetermined distances d1, d2, and d3 are provided. You can narrow it. In addition, it is preferable that the predetermined space | interval d of the conveyance amount adjustment material 10 provided in the magnet conveyor 1 of this invention is provided 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.
The present invention is most effective in conveying and aligning headed deformed members such as screws and pins.
A large amount of conveyed object M is supplied to the hopper (6). When the magnet conveyor (1) starts to operate, the chain (5) below the conveying surface (2) is operated.
The transfer object M is transported by the magnet (91) of the holder (9) provided in the chain (5). At this time, since the arrangement of the magnet (91) of the holding body (9) is the arrangement as described above (see FIG. 6), first, the first holding body (4) in which the four magnets (91) are arranged ( According to 9), the piles of the object to be conveyed M are broken, and the masses that have become smaller are conveyed.

Next, when passing through the first transport amount adjusting material (X), the overlapping transported object M is removed, and the transport amount is adjusted to a certain level to a certain extent (see FIG. 8). At this time, the removed transported object M is transported by the holding body (9) in which the next two or one magnet (91) is arranged. This holding body (9) Since the magnet arrangement different from that of the holder (9) conveyed first is performed, the object M to be conveyed is conveyed by an arrangement different from that of the first holder (9).
That is, quantification is performed so that a predetermined transport amount is transported by thinning out the transport object M transported by the holding body (9).

The transported object M that has reached the second transport amount adjusting material (Y) cannot be removed by the first transport amount adjusting material (X) by the second transport amount adjusting material (Y). The object M can be removed, and the object to be conveyed M is directed in a certain direction (direction along the flow of the conveying surface (2)) by the resistance force of the flexible member (A).
The transported object M that has passed through the second transport amount adjusting material Y has about one transported object M with respect to the magnet (91) included in the holding body (9) at this time.
When the vertical surface (23) is moved up and transported, the flow of the transport surface (2) and the transported object M are parallel to each other with the magnet (91) adsorbed by the weight of the transported object M as a rotation axis. It rotates on the vertical plane (23) until it becomes. Accordingly, the objects to be transported M are arranged and transported in the same direction as the flow of the transport surface (2) while moving up the vertical surface (23).
The conveyed object M that has been conveyed and arrived at the upper curved surface (24) is sent to the transfer passage (25).
Under the present circumstances, even if the to-be-conveyed object M which peels from the perpendicular | vertical surface (23) of a conveyance surface (2) and falls arises, this to-be-conveyed object M is received and conveyance surface (2) by the 3rd conveyance amount adjustment material (Z). Can be returned to.

Since the article (M) transferred to the transfer passage (25) passes through the demagnetizer (26), demagnetization is performed.
The article M to be demagnetized is transferred to the feeder (27) through the transfer passage (26) and the guide passage (26a). The conveyed object M transferred to the feeder (27) is disposed between the inclined portion (27a) and the guide plate (27b), and a part thereof is between the inclined portion (27a) and the guide plate (27b). The body part (M1) is sandwiched and aligned (see FIG. 12B).

The conveyed object M is transferred to the removing means (28) of the feeder (27). At this time, the removal means (28) is not aligned (the body portion (M1) is not sandwiched between the inclined portion (27a) and the guide plate (27b)). 28b) to be dropped into the notch (28a).
The aligned objects (M) are transported in the straight direction through the feeder (27).
At this time, the article M to be transported that has dropped onto the notch (28a) is transported through the transport path (29) to the hopper (6), and again from the hopper (6) to the magnet conveyor (1). Will be supplied.

Since the feeder (27) has the sensor (30), when it is detected that a larger amount of the object M to be conveyed than the predetermined setting is conveyed to the feeder (27), the magnetic conveyor (1) is stopped. The supply of the transferred object is automatically stopped.
