Conveying material alignment method and conveyed material alignment system

The present invention relates to a method for arranging (regular arrangement) of conveyed objects and a system for arranging conveyed objects.

Conventionally, as a conveying device such as a feeder, a configuration in which conveyed objects such as electronic components are aligned in a predetermined posture to an inspection device, a mounting device, a transfer device, a tapping device, and the like are known. A variety of conveying devices supplied by the target device. In this type of conveying device, the posture of the conveyed object on the conveying path is identified by appearance measurement, and the conveyed object having an unacceptable posture is removed from the conveying path by blowing air flow or the like on the conveyed object based on the identification result, or the conveyed object is removed from the conveying path. Rotate and change its posture to unify the posture of the conveyed object.

However, there are conveyed objects including a magnetic material, such as a multilayer ceramic capacitor, among the conveyed objects. In such a conveyed object provided with a magnetic material, since the posture can be detected by magnetism or the posture can be changed by magnetic force, various methods of detecting the posture of the conveyed object using electromagnets or permanent magnets have been proposed (refer to the following Patent Document 1) and a method of changing the posture (refer to the following Patent Documents 2 to 4). prior art literature Patent Literature

Patent Document 1: Japanese Patent Laid-Open No. 2014-130912 Patent Document 2: Japanese Patent Laid-Open No. 5-229634 Patent Document 3: Japanese Patent Application Publication No. 5-43468 Patent Document 4: Japanese Patent Laid-Open No. 2011-18698

However, there are electronic devices including external electrodes made of magnetic bodies and electronic devices including internal electrodes made of magnetic bodies such as multilayer ceramic capacitors as conveyed objects that can perform magnetic detection as described above or change their posture based on magnetic force. . For these devices, the direction of the magnet is set to match the standard posture, so that the conveyed object is controlled to the standard posture by the magnetic force. For example, in the above-mentioned Patent Document 4, all the internal electrodes 3 of the electronic device 1 are set in a posture that matches the direction of the magnetic flux of the first magnet 21 (see FIGS. 1( c ), 4 , 8 , and 11 ). In addition, in this document, the electronic device 1 is attracted to the conveying surface by the magnetic attraction force of the second magnet 22, and the standard posture is maintained.

However, in recent conveying apparatuses, it is required to convey a large amount of fine conveyed objects, so it is necessary to arrange the conveyed objects conveyed at a high density in an orderly manner. However, in the above-mentioned conventional method, the conveyed objects are changed one by one. Therefore, if the conveying speed is directly increased, the conveying posture will be obstructed, and the arrangement cannot be arranged at a high speed and efficiently. When changing the posture of the object to be conveyed, the back and forth objects are involved in the object, and the posture of the object already in the standard posture is disturbed.

Therefore, the present invention is an invention to solve the above-mentioned problems, and its subject is to provide a method for arranging the conveyed objects which can be efficiently and reliably arranged regularly by magnetic force to make the conveyed objects conveyed at high speed and high density unobstructed.

In order to solve the above-mentioned problems, the method for arranging the conveyed objects of the present invention is based on the direction of the magnetic flux generated by the magnets arranged beside the conveying path in the process of conveying the conveyed objects including the magnetic body along the conveying path toward the conveying direction. The posture of the conveyed objects is controlled, and the direction of the magnetic flux on the conveying path is changed to the conveying direction, whereby the conveyed objects are arranged in the first order on the conveying path by the magnetic force. In the conveying posture, in this method of aligning the conveyed objects, during the conveying process of the conveyed objects approaching the upstream side of the magnet by being conveyed on the conveying path, the conveyed objects are unified on the conveying path into the first position. Two conveying postures, and through the magnetic repulsion between the conveyed objects, the spacing deviation of the front and rear conveyed objects in the conveying direction is reduced, wherein the second conveying posture is the alignment direction of the conveyed objects and In the posture in which the conveying directions are inconsistent, the alignment direction should be consistent with the conveying direction in the first conveying posture; then, the conveyed objects are conveyed on the conveying path to be away from the downstream of the magnet During the side conveying process, the conveyed object gradually changes its posture on the conveying path according to the change of the direction of the magnetic flux on the conveying path to the conveying direction, thereby finally becoming the alignment direction and the direction of the conveying. The first conveying posture in which the conveying direction is the same is adopted, so that the conveyed objects are arranged in an orderly manner. In this way, the direction of the magnetic flux is gradually changed after being unified into the second conveying posture by the strong magnetic field, and is gradually guided to the first conveying posture by the gradually weakening magnetic field, so that even if the conveying speed is high, it is possible to efficiently and reliably without any trouble. Arrange in order.

In this invention, it is preferable that the said conveyance object has a longitudinal direction, and the said longitudinal direction is the said alignment direction which matches the said conveyance direction in the said 1st conveyance attitude|position. Thereby, when the conveyed object approaches the magnet, the conveyed objects are unified on the conveying path into the second conveyance in which the longitudinal direction of the conveyed object does not coincide with the conveying direction Since it is easy to widen the interval between the conveyed objects before and after the posture, it is easy to further unify the deviation of the interval, so that the conveyed objects can be arranged more neatly in the first conveying posture. In this case, the second conveyance posture is preferably a posture in which the longitudinal direction is perpendicular to the conveyance direction. Thereby, since the interval between the objects to be conveyed can be further widened when the second conveyance posture is unified, it is easy to further unify the deviation of the interval, and finally, the objects to be conveyed can be arranged more neatly.

In this invention, it is preferable that the said conveyance object contains the said magnetic body so that the attitude|position in which the said alignment direction follows the direction of the said magnetic flux may be stabilized. In this way, the alignment direction of the conveyed objects can be controlled by the direction of the magnetic flux, and therefore, the magnetic flux distribution of the following form can be easily realized by setting the strength and position of the magnets, that is, after arranging in the second conveying posture A desired state of alignment in the first conveyance posture can be obtained. In this case, the alignment direction is preferably the longitudinal direction of the conveyed object. Moreover, it is preferable that the said 2nd conveyance attitude|position is the attitude|position in which the said alignment direction and the said conveyance direction are perpendicular|vertical. Furthermore, in this case, it is preferable that the said magnet has the magnetic pole which faces the direction perpendicular|vertical to the said conveyance direction with respect to the said conveyance path. However, the magnet may be arranged so that the direction in which a pair of magnetic poles are connected is parallel to the conveying direction with respect to the conveying path.

In the present invention, it is preferable that during the conveying process on the downstream side, as the conveyed object is conveyed toward the conveying direction and the magnetic influence exerted by the magnet on the posture of the conveyed object is reduced, The direction of the magnetic flux gradually approaches from the second direction corresponding to the second conveying posture to the first direction corresponding to the first conveying posture. Thereby, the position of the conveyed object can be smoothly changed from the second conveying position to the first conveying position, and the direction of the magnetic flux does not exceed the first direction until the magnetic influence of the magnet disappears, so there is no The first conveying posture of the conveyed object will be disturbed.

In this invention, it is preferable that the said conveyance path is comprised so that the said conveyance may be conveyed by the reciprocating vibration toward the diagonal front upper direction of the said conveyance direction. As a result, the conveyed object is conveyed in a suspended state through the above-mentioned vibration on the conveying path, so that the attitude control of the conveyed object by magnetism can be performed easily and with high accuracy.

In this invention, it is preferable that the said conveyance path is provided with the conveyance bottom surface part which has the cross-sectional profile of a concave curved surface. In this case, the conveying bottom portion having a circular groove such as an arc or U-shape, or other concavely curved cross-sectional profile, preferably has a shape in which the flat surface is smaller than the contact area of the conveyed object. Specifically, it is preferable that the radius of curvature R of the conveying bottom surface is larger than half of the maximum dimension K of the conveying object. In addition, when the conveyed object is in the shape of a rectangular parallelepiped, the maximum dimension K is the square root of the sum of the squares of the length L, the width W, and the height H, that is, K=(L ² +W ² +H ² ) ^1/2 . Here, when L>W and L>H, it is more desirable that the curvature radius R is larger than (1/2)L. In addition, the curvature radius R of the said conveyance bottom surface part may have a different value according to a position. However, it is preferable that the entire portion of the concave curved surface has a radius of curvature R that satisfies all of the above-mentioned conditions.

Next, the conveyed object arranging system according to the present invention includes a conveying object including a magnetic body, a conveying path for conveying the conveying object toward the conveying direction, and a magnet, and the magnet is arranged beside the conveying path and is located in the conveying path. A magnetic flux distribution that affects the conveying posture of the conveyed object is formed on the conveying route within at least a predetermined range in the conveying direction of the conveying path, and the conveyed object alignment system makes the conveyed object regular in the first conveying posture In this conveyed object alignment system, the conveyed object in which the magnetic flux is distributed in the predetermined range is conveyed on the conveying path toward the conveying direction and approaches the upstream side conveying path of the magnet In the area, the direction of the magnetic flux is gradually changed to a direction perpendicular to the conveying direction in such a way that the conveyed object is gradually guided to a second conveying posture different from the first conveying posture; The flow is distributed in the conveying path region on the downstream side of the conveying object away from the magnet by being conveyed on the conveying path toward the conveying direction, so as to gradually move the conveying object from the second conveying posture to the conveying direction. The first conveying posture guide is such that the direction of the magnetic flux is gradually changed toward the conveying direction.

In the present invention, it is preferable that the conveyed object has a longitudinal direction, and the longitudinal direction corresponds to the conveying direction in the first conveying posture. In this case, the second conveyance posture is preferably a posture in which the longitudinal direction is perpendicular to the conveyance direction.

In the present invention, it is preferable that the conveyed object contains the magnetic body so as to be stable in a posture in which the conveying direction in the first conveying posture coincides with the conveying direction along the direction of the magnetic flux. . In this case, the aligned direction is preferably the longitudinal direction of the conveyed object. Moreover, it is preferable that the said 2nd conveyance attitude|position is the attitude|position in which the said matched direction and the said conveyance direction are perpendicular|vertical. Furthermore, in this case, it is preferable that the said magnet has the magnetic pole which faces the direction perpendicular|vertical to the said conveyance direction with respect to the said conveyance path.

In the present invention, in the downstream conveyance path region, the conveyance is preferably carried out as the conveyance is conveyed toward the conveyance direction and the magnetic influence exerted by the magnet on the posture of the conveyance decreases. The direction of the magnetic flux on the road gradually approaches from the second direction corresponding to the second conveyance posture to the first direction corresponding to the first conveyance posture.

In the present invention, it is preferable to further include a discrimination control unit that controls the downstream side of the conveyance path region on the downstream side and at a position where the conveyed objects are arranged and conveyed in the first conveying posture. The conveyed object is discriminated, and the conveyed object is controlled according to the discrimination result. Examples of the discrimination control unit include a discrimination exclusion unit that excludes defective products or conveyed objects of poor posture from the above-mentioned conveyance path, and a discrimination inversion unit that rotates conveyed objects of poor posture to change the posture. (Inventive effect)

According to the present invention, it is possible to provide a method for arranging the conveyed objects, which can make the conveyed objects conveyed at high speed and high density without obstacles, efficiently and reliably arrange them regularly by magnetic force.

Next, embodiments of the present invention will be described in detail with reference to the drawings. First, with reference to FIG. 1 and FIG. 2, the vibrating conveying apparatus which comprises the conveyed object arranging system of this invention is demonstrated. The vibrating conveying device 100 includes a conveying object supply unit 110 provided on an installation table 101 , a first conveying unit 120 for conveying conveying objects supplied from the conveying object supply unit 110 , and the first conveying unit The second conveying part 130 of the conveyed material supplied from 120 . Since the first conveyance unit 120 and the second conveyance unit 130 are provided with vibration exciters, they are mounted on the support table 102 provided on the above-described installation table 101 via a vibration-absorbing material (coil spring, etc.) for vibration isolation. The conveyed material supply unit 110 includes a drive unit 111 and a hopper 112 attached to the drive unit 111 , and discharges the conveyed material on the hopper 112 to the first conveyance unit 120 .

The first conveying unit 120 is a so-called bowl feeder, and includes a rotary vibration exciter 121 and a bowl-shaped vibrating body 122 attached to the rotary vibration exciter 121 . The vibrating body 122 is provided with a conveying path 122t spirally ascending from the inner bottom, and the conveyed objects supplied to the inner bottom of the vibrating body 122 are slowly ascended along the conveying path 122t by the rotational vibration applied by the rotary vibration exciter 121 . Arrange in order.

The second conveyance unit 130 is a so-called linear feeder, and includes a linear vibration exciter 131 and linear vibrating bodies 132 and 133 attached to the linear vibration exciter 131 . Here, the vibrating body 132 includes a linear supply conveying path 132t connected to the outlet end of the conveying path 122t. In addition, the vibrating body 133 includes a conveying path 133t extending in parallel with the conveying path 132t, and the conveying path 133t is a conveying path for receiving the conveyed objects excluded from the conveying path 132t, and the conveying path 133t is opposite to the conveying path 132t. The conveyed object is conveyed in the direction, and the conveyed object is returned to the conveying path for recovery in the above-mentioned vibrating body 122 .

The magnet 137 is arrange|positioned by the said conveyance path 132t. The magnet 137 is not limited to various permanent magnets such as neodymium magnets, for example, and may be electromagnets. The magnet 137 is attached to the attachment member 136 held via the support arm 135 attached to the support member 134 attached to the support base 102 described above. In the illustrated example, the mounting member 136 is disposed on the vibrating body 132 side by passing the support arm 135 over the vibrating bodies 132 and 133 relative to the supporting member 134 provided on the vibrating body 133 side, so that the magnet 137 It is arranged at a position adjacent to the vibrating body 132 from the side opposite to the support member 134 . In the illustrated example, the vibrating bodies 132 and 133 are made of (non-magnetic) stainless steel such as SUS303 and 304, or a non-magnetic body such as aluminum or an aluminum alloy such as A5051 and A5052, as will be described later.

Next, the conveyed object according to the present invention will be described with reference to FIGS. 3 and 4 . As shown in FIG. 3, the conveyed object CA conveyed in this embodiment is comprised in the shape of a rectangular parallelepiped. The conveyance CA of the illustrated example is a multilayer ceramic capacitor including external electrodes OE1 and OE2 on the outside of both ends, and a plurality of internal electrodes IE1 and IE2 sandwiched by a dielectric body DE such as a ceramic layer inside the capacitor. In some cases, the internal electrodes IE1 and IE2 are made of Ni, and the external electrodes OE1 and OE2 are made of Cu. In the above-mentioned example, since the internal electrodes IE1 and IE2 are surrounded by a non-magnetic material such as a dielectric body DE such as a ceramic layer, the material Ni is a ferromagnetic material, so the conveyed object CA is strongly influenced by the magnetic field. In the illustrated example, the alignment direction of the conveyed object CA (corresponding to the longitudinal direction in the illustrated example), the alignment direction of the axis CAx coincides with the longitudinal direction of the internal electrodes IE1 and IE2. The alignment direction of the alignment direction (longitudinal direction) axis CAx corresponds to the conveyance direction F in the first conveyance posture which is the standard posture of the conveyed object CA.

As shown in FIG. 4 , when the conveyed object CA is placed in the magnetic field (magnetic flux distribution) generated between the pair of magnetic poles Ms of the magnet M, the longitudinal direction of the internal electrodes IE1 and IE2 which are ferromagnetic bodies (Fig. Since the magnetic polarization is generated in the direction of the length L indicated by 3) and becomes stable, the conveyed object CA is guided in such a posture that the direction of the length L follows the direction of the magnetic flux. In addition, since the internal electrodes IE1 and IE2 also follow the direction of the width W, when the direction of the width W and the direction of the height H are compared, the direction of the width W is more along the direction of the magnetic flux than the direction of the height H. The situation along the direction of the magnetic flux is more stable.

As shown in FIG. 5 , in the illustrated example, one magnetic pole 137 a of the magnet 137 is provided so as to face the conveyance path 132 t of the vibrating body 132 . Here, the conveyance path 132t facing the magnet 137 is a circular groove-shaped conveyance path portion 132tr having a bottom surface portion 132trb having a concavely curved cross-sectional profile. The above-mentioned cross-sectional profile may be an arc shape or a U-shape, but is preferably a smooth curved shape that allows easy change of the posture of the conveyed object CA. For example, the concave curved surface shape of the bottom surface portion 132trb of the conveyance path portion 132tr is set so that the radius of curvature R satisfies the condition represented by the formula R>(1/2)·L with respect to the length L of the conveyed object CA. More generally, in the above formula, the square root of the sum of the squares of the length L, the width W, and the height H (L ² +W ² +H ² ) may be used as the maximum dimension K of the conveyed object CA instead of the length L. ^1/2 . In the illustrated example, the cross-sectional shape perpendicular to the conveyance direction F of the bottom surface portion 132trb is an arc shape having a constant curvature radius R, but the curvature radius R may vary within the bottom surface portion 132trb. In this case, the average value of the curvature radius R of the bottom surface portion 132trb should just satisfy the above-mentioned conditions. However, it is more desirable that the entire curvature radius R of the bottom surface portion 132trb satisfies the above conditions. In addition, the upper limit of the radius of curvature R is preferably 5 times or less of the above-mentioned L or K, more preferably 3 times or less.

Moreover, as shown in FIG. 5, the magnetic pole 137a of the magnet 137 is arrange|positioned so that the said conveyance path part 132tr may be opposed to a horizontal direction. However, the magnetic pole 137a of the magnet 137 may be arranged so as to face the above-mentioned conveyance path portion 132tr from an up-down inclination direction. Furthermore, when the conveyance direction to be aligned is different from the embodiment, the direction connecting a pair of magnetic poles may be parallel to the conveyance direction F of the conveyance path, or may be arranged to face each other from above or below.

The vibrating body 132 shown in FIG. 5 actually shows a part of the vibrating body 132 , that is, a conveying section having a conveying path 132t. The conveying section is preferably made of a non-magnetic material such as non-magnetic stainless steel, aluminum, or aluminum alloy as described above. This is because the direction of the magnetic flux on the conveyance path 132t is not easily affected because the magnetic flux Φm passes through the conveyance section. This is especially true when the conveyance path 132t itself becomes a shadow of the conveyance section when viewed from the magnetic pole 137a of the magnet 137 in the direction of the magnetic flux Φm as in the example of the figure.

As shown in FIG. 6 , the magnetic field (magnetic flux distribution) formed by the magnet 137 forms the magnetic flux Φm shown by the two-dot chain line in the figure. Here, the magnetic flux Φm is represented by the product of the surface area Sm of the magnetic pole 137 a (Ms) and the magnetic flux density Bm on the magnetic pole 137 a (Ms). In addition, the distance Dm between the magnetic pole 137a (Ms) and the closest position 132tr0 of the conveyance path part 132tr is set according to the magnitude of the magnetic flux Φm. In addition, in this embodiment, since the magnet 137 is provided so that the magnetic pole 137a faces the conveyance path 132t, the said closest position 132tr0 becomes the position which the magnetic pole 137a faces.

If the above-mentioned closest position 132tr0 on the conveyance path 132t is used as a reference, when the conveyance CA is conveyed on the conveyance path 132t in the conveyance direction F, the conveyance path area on the upstream side is more upstream than the above-mentioned closest position 132tr0 In 132tr1, the conveyed object CA gradually approaches the magnet 137 as it is conveyed. Therefore, during this upstream conveying process, the magnetic flux density on the conveying path 132t gradually increases, and the direction of the magnetic flux Φm on the conveying path 132t increases from The conveyance direction F is gradually changed to a direction (width direction) perpendicular to the conveyance direction F. As shown in FIG. On the other hand, in the downstream side conveyance path region 132tr2 on the downstream side of the above-mentioned closest position 132tr0, the conveyed object CA gradually moves away from (away from) the magnet 137 as it is conveyed. Therefore, during this downstream conveyance process, The magnetic flux density on the conveyance path 132t gradually decreases, and the direction of the magnetic flux Φm gradually changes from the direction perpendicular to the conveyance direction F to the conveyance direction F. As shown in FIG.

In the present embodiment, in the above-mentioned conveyance path portion 132tr, the direction of the magnetic flux is at the most upstream portion within the magnetic influence range 132trs of the conveyance path where the magnetic influence of the magnet 137 acts on the conveyance CA on the conveyance path 132t. In accordance with the conveyance direction F, the direction of the magnetic flux is perpendicular to the conveyance direction F at the closest position 132tr0 described above, and further, at the most downstream portion, the direction of the magnetic flux matches the conveyance direction F again. In addition, the said magnetic influence means the influence of the attitude|position change of the conveyance object CA on the conveyance path 132t by the magnet 137. FIG. That is, the magnetic influence range 132trs of the above-mentioned conveyance path is a range in which the orientation of the conveyed object CA, viewed in the conveyance direction F of the conveyance path 132t, is influenced by the direction of the magnetic flux of the magnet 137 . In the present embodiment, the conveying object CA is conveyed in a state of floating on the conveying path 132t for a large number of times by the vibration conveying, and the conveying path portion 132tr is formed in a concave curved surface shape with the conveyed object. Since the contact area of CA becomes small, the posture of the conveyed object CA can be easily changed.

Normally, on the conveyance path 132t, the conveyance CA is conveyed in the conveyance direction F in various postures. In particular, in a vibrating conveying device, since the conveyed object CA travels in a suspended state through the vibration of the vibrating body 132, the posture of the conveyed object CA is easily changed, and as long as there is no restriction in the width direction, the conveying path is the same. As shown in the upstream portion of the magnetic influence range 132trs, the conveying posture of the conveyed object CA and the interval at the time of conveying are also disturbed. When the conveyed object CA advances in the upstream conveyance path region 132tr1 in this state, as shown by the magnetic attraction force Q shown in FIG. , the alignment direction (longitudinal direction) axis CAx, which is the direction of the length L of the conveyed object CA, is also gradually inclined. Finally, in the vicinity of the closest position 132tr0, corresponding to the fact that the direction of the magnetic flux is perpendicular to the conveyance direction F, the alignment direction axis CAx of the conveyed object CA is also perpendicular to the conveyance direction F. In addition, in this upstream conveyance path region 132tr1, the conveyance CA receives a slight magnetic attraction force Q due to the component of the magnetic flux in the conveyance direction F, so that the conveyance speed and the interval between conveyed objects CA slightly increase . In addition, in the example shown in the figure, there are many conveyed objects CA whose longitudinal direction is along the conveying direction F at first, and thereafter, due to the magnetic influence of the magnet 137, the conveyed objects CA gradually change their posture so that the longitudinal direction is perpendicular to the conveying direction F, so that the conveying path is The distance interval of the conveyance CA on 132t also gradually increases.

The conveyed object CA in the posture (second conveying posture) in which the alignment direction (longitudinal direction) axis CAx is perpendicular to the conveying direction F in the vicinity of the closest position 132tr0 is mainly the magnetic polarization (magnetization) of the internal electrodes IE1 and IE2 in the longitudinal direction. ). At this time, a mutual repulsive force is generated between the front and rear conveyed objects CA that are magnetized in the same direction in the same posture, and thus the distance from each other is increased, and the deviation of the distance from each other is reduced. In an ideal situation, the intervals of the plurality of conveyed objects CA at the position close to the closest position 132tr0 are approximately equal in the front and rear.

When the conveyed object CA passes through the closest position 132tr0, this time it moves away from the magnet 137 as it advances in the conveying direction F. Therefore, in the downstream conveying path region 132tr2, as opposed to the upstream conveying path region 132tr1 described above, it moves along the conveying direction F. The conveying direction F advances with the magnetic influence gradually decreasing, and the direction of the magnetic flux gradually inclines from the direction perpendicular to the conveying direction F and gradually changes toward the conveying direction F. FIG. Then, when the direction of the magnetic flux becomes a direction close to the conveying direction F and the alignment direction (longitudinal direction) axis CAx of the conveyed object CA approaches the conveying direction F corresponding to the magnetic flux, the magnetic attraction force Q shown in FIG. As shown in the figure, the magnetic influence gradually becomes smaller, and the posture change does not occur. Therefore, the conveyed object CA takes the conveying posture (first conveying posture) in which the alignment direction (longitudinal direction) axis CAx is aligned with the conveying direction F (first conveying posture), and maintains this The posture is advanced to the downstream side. At this time, the queue of the conveyed object CA starts from the upstream conveyance path region 132tr1 and passes through the closest position 132tr0, thereby reducing the deviation of the posture and the deviation of the interval in the second conveyance posture. When the conveyance path region 132tr2 is restricted to the first conveyance posture, a neatly aligned state (regularly aligned state) can be obtained. However, in this alignment state, the alignment is performed in the first conveyance posture in which the alignment direction axis CAx of the conveyed objects CA coincides with the conveyance direction F. However, in the case of the illustrated example, the first conveyance posture may include the following The above two postures are both: a posture in which the surface of the width W corresponding to the width direction of the internal electrodes IE1 and IE2 faces the bottom surface portion 132trb, and a posture in which the surface of the height H faces the bottom surface portion 132trb.

In the present embodiment, in the downstream conveyance path region 132tr2, as the conveyance CA is conveyed toward the conveyance direction F and the magnetic influence exerted by the magnet 137 on the posture of the conveyance CA is reduced, the magnetic flux Φm on the conveyance path 132t becomes smaller. The direction gradually approaches from the second direction corresponding to the second conveyance posture to the first direction corresponding to the first conveyance posture. Thereby, the conveyed object CA is gradually guided from the second conveying posture to the first conveying posture, and does not receive an opposite magnetic force (eg, returning to the second conveying posture), so even when being conveyed at a high speed , Even in the case of high-density conveyance, the conveyed objects CA can be efficiently and reliably aligned in the first conveyance posture. In order to form such a magnetic flux distribution, it is preferable to adjust the magnetic force of the magnet 137, the aforementioned distance Dm, and the like. In this embodiment, since the position of the attachment member 136 can be adjusted, the above-mentioned distance Dm can be adjusted. However, for example, the magnetic flux distribution may be adjusted by replacing the magnet 137 or by adjusting the power value such as the current value when an electromagnet is used. In this case, it is further preferable to analyze the magnetic influence on the conveyed object by processing the image obtained by the photographing device such as a camera, especially the above-mentioned closest position 132tr0 and its periphery or the downstream conveying path area 132tr2. The above-mentioned distance Dm or the above-mentioned power value is automatically controlled by analyzing the conveying posture of the conveyed object or its change form. For image processing in this case, AI such as pattern matching processing or a learned neural network can be used. Preferably, the manual distance Dm or power value adjustment unit or the automatic distance Dm or power value adjustment unit is installed on the controller of the conveying system.

FIG. 7 shows a wider extent of the transport path 132t. In the conveyance path 132t, a conveyance path portion 132tp is provided on the upstream side of the conveyance path portion 132tr, and a conveyance path shape having a flat bottom surface portion 132tpb is formed on the conveyance path portion 132tp. The flat bottom surface portion 132tpb has a characteristic that the conveyance posture of the conveyed object CA is relatively stable. At this time, in the illustrated example, by providing the conveyance path portion 132tp with a wide bottom surface portion 132tpb, it is possible to carry out the process in a state including the conveyed object CA with the alignment direction (longitudinal direction) axis CAx facing the width direction. delivery. Then, in the above-mentioned conveyance path portion 132tr, since the concave curved bottom surface portion 132trb makes it easy to change the conveyance posture of the conveyed object CA, the magnetic action by the magnet 137 is easily generated in the magnetic influence range 132trs of the conveyance path. posture changes.

On the other hand, the conveyance path part 132ts is connected to the downstream side of the conveyance path part 132tr. In this conveyance path portion 132ts, by having a conveyance path shape having a flat bottom surface portion 132tsb, the stability of the conveyance posture of the conveyed object CA becomes high. Here, the width dimension of the conveyance path portion 132ts is preferably a value corresponding to the first conveyance posture. In the case of the illustrated example, since the first conveyance posture is that the alignment direction (longitudinal direction) matches the conveyance direction F, the width of the bottom surface portion 132tsb is configured to be narrower than the upstream conveyance path portions 132tp and 132tr.

In this conveyance path part 132ts, the discrimination|determination control part 132S is provided in the conveyance path 132t. The discrimination control unit 132S is provided with an area for discriminating the appearance, posture, and other characteristics of the conveyed object CA, that is, a measurement area ME, and the conveyed object CA is discriminated by performing various measurements in the measurement area ME. The conveyed object CA is removed from the conveyance path 132t according to the discrimination result, or the conveyance posture is reversed. In the case of the illustrated example, when the conveyed object CA is discriminated through its image processing based on the image captured by the camera CM, and it is determined that the conveyed object CA is not suitable to be directly conveyed to the downstream side, the use of The air flow blown from the air outlet OP removes the conveyed object CA from the conveyance path 132t, or changes the posture of the conveyed object CA by inversion or other rotational action. As an example of the discrimination control unit 132S, it is possible to discriminate whether or not the rotational posture of the conveyed object CA around the alignment direction (longitudinal direction) axis CAx is appropriate.

In addition, the method and apparatus of the present invention are not limited to the above-described examples, and it goes without saying that various modifications can be added without departing from the gist of the present invention. For example, in the above-described embodiment, a posture is set such that one magnetic pole 137a of the magnet 137 faces the closest position 132tr0 of the conveyance path 132t, and the following magnetic flux distribution is formed in the magnetic influence range 132trs of the conveyance path.

For example, the magnets may be arranged such that the arrangement direction of a pair of magnetic poles is parallel to the conveyance path 132t, and the directions of the magnetic fluxes may be formed to be close to the conveyance direction F on the upstream side and the downstream side. The magnetic flux distribution is such that the vertical direction substantially matches the conveyance direction F in the vicinity of the closest position 132tr0. In this case, the conveyed object may be configured to assume the first transport posture when the direction of the magnetic flux is perpendicular to the transport direction F, and to assume the second transport posture when the direction of the magnetic flux coincides with the transport direction F. In addition, in the above-described embodiment, the case where the alignment direction axis CAx of the conveyed object CA is the longitudinal direction, and the alignment direction axis CAx is along the direction of the magnetic flux Φm is determined by the magnetic force The posture of the conveyed object CA is determined. However, the present invention is not limited to this case, and the alignment direction axis CAx may be in a direction other than the longitudinal direction. In addition, the alignment direction axis CAx may not be in the direction of the magnetic flux Φm, but may be, for example, in a direction similar to the magnetic flux Φm. A stable conveyance CA is maintained in the vertical direction of Φm.
