Abstract

The present invention provides a posture changing device capable of holding a conveyed object in a standard posture, and changing the posture of a conveyed object in a poor posture. The posture changing device mounted on a vibrating conveyor device is characterized by having an injection hole (50b) opened at a bottom part of a conveyance path of the vibrating conveyor device, and an air supply unit that supplies compressed air to the injection hole (50b). Thereby, the conveyed object can be pushed in the conveying direction through the vibration of the vibrating conveyor device and the compressed air ejected from the injection holes. In addition, in contrast to the case where the injection hole is arranged above the conveyance path, the injection hole is close to the conveyed object on the conveyance path, so that the compressed air can be accurately brought into contact with the desired conveyed object, and the orientation of the injection hole can be prevented from changing during use of the vibrating conveyor device.

Description

posture changing device

The present invention relates to a posture changing device used in a vibrating conveyor. That is, it relates to a posture changing device mounted on a vibration-type conveying device that conveys conveyed objects (parts) through vibration, that is, a so-called feeder (Parts Feeder).

(a) to (c) in FIG. 11 are explanatory diagrams showing a state in which a conveyed object is conveyed by a vibrating conveyor. As shown in (a) to (c) of FIG. 11 , generally speaking, the vibration conveyor 70 vibrates the conveyance path 72 with the vibration V using an exciter (not shown), thereby conveying the conveyance object CN in the conveyance direction F. . This vibration V reciprocates obliquely upward on the downstream side and obliquely downward on the upstream side in the conveyance direction F. Specifically, the conveyed object CN starts from the first position P1 ((a) in FIG. 11 ) on the conveying path 72 and moves obliquely upward from the conveying path 72 in the conveying direction F, that is, in the injection direction T. It flies up ((b) in FIG. 11) and lands at the second position P2 of the conveyor path 72 ((c) in FIG. 11). Thereby, each time the conveyed object CN flies up due to the vibration V, it is conveyed toward the conveying direction F by the distance d between the first position P1 and the second position P2.

At present, as described in Patent Document 1, for example, as a conventional posture changing device used in such a vibrating conveying device, a vibrating conveying device configured to convey toward the conveyor from an upper position of the conveying path has been proposed. By injecting compressed air diagonally downward toward the downstream side and installing obstacles on the wall of the conveyor path, thrust is exerted on the conveyed object and the conveyed object is caught on the obstacle and rotated, thereby moving the conveyed object from its unfavorable posture. Change to standard posture.

In addition, for example, as described in Patent Documents 2 and 3, a vibrating conveyor device is proposed that is configured to inject air obliquely toward the downstream side in the conveying direction from the left and right sides of the conveying path toward the center to prevent The rupture, defect, stagnation, and blockage of the conveyed material will cause the conveyed material to be transported.

Furthermore, for example, as described in Patent Documents 4 to 6, a conveying device is proposed which is configured to inject air diagonally upward from the bottom of the conveying path toward the downstream side in the conveying direction, and to suspend the conveyed object on the conveying path. At the same time, it is adjusted to the standard posture for transportation. Prior technical literature patent documents

However, the vibrating conveyor (component conveyor) described in Patent Document 1 injects compressed air diagonally downward from the upper position of the conveyor path toward the downstream side in the conveyance direction, so there is a predetermined distance from the air injection port to the conveyor path. distance, there is a problem that the compressed air diffuses from the air injection port until it comes into contact with the conveyed object, making it difficult to accurately bring the compressed air into contact with the desired conveyed object, and because the air injection port is arranged at the edge of the conveying path Since the direction of the air injection port can be changed due to the upward position, there is a problem that if the direction of the air injection port deviates from the set posture, it is very difficult to return the direction of the air injection port to its original state.

The vibrating conveying devices (vibrating feeders, conveying devices) described in Patent Documents 2 and 3 inject compressed air obliquely toward the downstream side of the conveying direction from the left and right sides of the conveying path toward the center, so that the surrounding area of the conveying path is The structure becomes complicated, so there are problems such as the vibrating conveyor device becomes larger and the manufacturing cost increases. In particular, when the conveyed objects are electronic components, the size of the vibrating conveyor device is incompatible with the times as electronic components have been miniaturized recently.

The conveying devices described in Patent Documents 4 to 6 (air flow posture arrangement conveying device, air flow arrangement bottle cap feeder, container arrangement method) are conveying devices that use air flow to float conveyed objects and convey them. There is a problem that if this conveyor device is directly applied to a vibration-type conveyor device that conveys conveyed objects by vibration as shown in (a) to (c) in Figure 11, the conveyed objects may be blown up more than necessary, which may cause the conveyor to blow up. As a result, the standard posture of conveyed objects is distorted.

Therefore, the present invention was completed in order to solve the above-mentioned problems, and its subject is to provide a posture changing device that can maintain the standard posture of the conveyed object and change the defective posture of the conveyed object into the standard posture.

In order to solve the above problem, the attitude changing device of the present invention is mounted on a vibrating conveyor, and is characterized by having an injection hole opened at the bottom of a conveyance path of the vibrating conveyor and an air supply for supplying compressed air to the injection hole. supply unit.

According to the present invention, the posture changing device is mounted on a vibrating conveyor and has an injection hole opened at the bottom of a conveyance path of the vibrating conveyor and an air supply unit for supplying compressed air to the injection hole, thereby making it possible to The conveyed object is pushed in the conveying direction by both the vibration of the vibrating conveyor device and the compressed air injected from the injection hole, and compared with the case where the injection hole is arranged above the conveying path, due to the The injection hole is close to the conveyed object on the conveying path, so that the compressed air can be accurately contacted with the desired conveyed object, and the direction of the injection hole can be prevented from changing during use of the vibrating conveying device.

In the present invention, it is preferable that the conveyed object conveyed by the vibrating conveyor device is a substantially rectangular parallelepiped, and the posture in which the longitudinal direction extends along the conveying direction is set as the standard posture, and the longitudinal direction is orthogonal to the conveying direction. When the posture extending in the direction is a bad posture, let the length of the longitudinal direction of the conveyed object be L and the inclination angle of the conveyed object be αt, so that the distance between conveyed objects connected in the conveying direction is Compressed air is injected from the injection hole at a distance greater than L/2·sinαt.

According to the present invention, the conveyed object conveyed by the vibrating conveyor device is a substantially rectangular parallelepiped, and the posture in which the longitudinal direction extends in the conveying direction is regarded as the standard posture, and the posture in which the longitudinal direction extends in the direction orthogonal to the conveying direction is regarded as the standard posture. In the case of a bad posture, when the length of the conveyed object in the longitudinal direction is L and the inclination angle of the conveyed object is αt, the distance between the conveyed objects connected in the conveying direction is greater than L/ By injecting compressed air from the injection holes in the 2. sinαt method, conveyed objects with poor postures can be rotated without coming into contact with conveyed objects before and after the conveying direction. In addition, the tilt angle αt and the distance L/2·sinαt change with time t.

In the present invention, it is preferable that the injection hole extends from the lower side of the conveyance path to The bottom of the conveyor path. According to the present invention, the injection hole extends from the lower side of the conveying path to the conveying path at an inclination angle ranging from 15° to 25° from bottom to upward when the upstream side of the conveying direction is set to 0°. The bottom of the conveyor path is injecting compressed air through the injection hole from the bottom of the conveyor path at an inclination angle ranging from 15° to 25° upward when the downstream side of the conveyance direction is 0°. Therefore, , the compressed air can be sprayed at an acute angle toward the downstream side of the conveying direction, which can suppress the conveyed objects from being blown upwards on the conveying path, and can push the conveyed objects in the conveying direction while maintaining the standard posture, thereby expanding the flow of compressed air The distance between a pushed conveyor and its subsequent conveyor.

In the present invention, it is preferable that compressed air is always injected from the injection hole. According to the present invention, since the compressed air is always injected from the injection hole, the conveyed object reaching the opening of the injection hole can be continuously pushed in the conveying direction.

In the present invention, it is preferable that a plurality of the injection holes are provided at a predetermined interval along the conveying direction at the bottom of the conveying path. According to the present invention, since a plurality of the injection holes are provided at predetermined intervals in the conveying direction at the bottom of the conveying path, the same conveyed object can be given multiple opportunities to change its posture.

In the present invention, it is preferable that the injection hole is formed by connecting a feed member in which a groove is formed and an opposing member, and the injection hole is formed by the bottom surface and inner surface of the groove and the opposing member. It is surrounded by the surfaces that are in contact with the feeding component.

According to the present invention, since the injection hole is formed by docking the feed member formed with the groove and the opposing member, the injection hole is formed by the bottom surface and the inner surface of the groove in the feed member and the The facing member is surrounded by the surface that is in contact with the feeding member. Therefore, the injection hole can be formed more easily than when the injection hole is formed by punching a member made of one block. Moreover, the inclination angle and size of the injection hole can be easily set. (invention effect)

As described above, according to the present invention, since the compressed air is supplied through the air supply unit to the injection hole opened at the bottom of the conveying path of the vibrating conveying device, the following excellent effect can be achieved: the vibration of the vibrating conveying device can be transmitted through Both the compressed air from the injection hole and the compressed air from the injection hole maintain the posture of the conveyed object in the standard posture, and change the posture of the conveyed object in the defective posture.

The first linear feeder 20 and the second linear feeder 30 are arranged adjacent to each other so that their conveying directions F and R are opposite to each other. One conveyor path 22 in the first linear feeder 20 is configured to extend along the longitudinal direction of the conveyor body 21 and to be able to deliver conveyed objects in a standard posture to other devices at the downstream end 22a. The other conveyance path 23 extends parallel to the one conveyance path 22 and conveys conveyed objects excluded from the one conveyance path 22 due to poor posture in the same conveyance direction F as the one conveyance path 22 . The downstream end of the other conveyance path 23 of the first linear feeder 20 and the upstream end of the conveyance path 32 of the second linear feeder 30 are connected so as to be able to deliver conveyed objects. The downstream end of the conveyance path 32 of the second linear feeder 30 is connected to the upstream end of one conveyance path 22 of the first linear feeder 20 so as to be able to deliver conveyed objects. Thereby, the conveyed material is configured to circulate between the first linear feeder 20 and the second linear feeder 30 . The hopper 40 is used to store conveyed materials and to gradually and in small amounts input the conveyed materials into the conveying path 32 of the second linear feeder 30 .

FIG. 3 is an enlarged view schematically showing the range enclosed by the dashed-dotted line A in FIGS. 1 and 2 . As shown in FIG. 3 , the conveyed object CN is conveyed on the conveying paths 22, 23, and 32 of the vibration conveying device 10. The conveyed object CN is not particularly limited. It is assumed that the conveyed object CN is a rectangular parallelepiped with rounded corners, and the length L in the long side direction is greater than the width W and thickness in the short side direction (L>W). As an example, the conveyed object CN is an electronic component such as a resistor, a laminated ceramic capacitor, an inductor, a diode, a transistor, etc., and electrodes are provided at both ends in the longitudinal direction. The size of the conveyed object CN is not particularly limited. It can be 0603 (L=0.6mm×W=0.3mm), 0402 (L=0.4mm×W=0.2mm), or 0201 (L=0.25). mm×W＝0.125mm).

Returning to FIGS. 1 and 2 , the posture changing device 50 of this embodiment is installed at a position surrounded by the one-dot chain line A of the vibrating conveyor device 10 . Specifically, the attitude changing device 50 is mounted on the conveyor body 21 of the first linear feeder 20 and is disposed in the center of the conveyor path 22 of the first linear feeder 20 .

As shown in FIGS. 4 and 5 , the posture changing device 50 includes a feeding member 51 , an opposing member 52 , and an air supply unit (not shown).

Here, in FIGS. 3 to 7 , the direction indicated by the arrow Up is the upper side (in FIG. 3 , it is the front side of the paper, and in FIGS. 4 to 7 , it is the upper side of the paper). Let the direction indicated by the arrow Dw be the lower side (in Fig. 3, it is the back side of the paper, and in Figs. 4 to 7, it is the lower side of the paper.). Set the directions indicated by arrow Up and arrow Dw to the up and down directions. Let the direction indicated by the arrow In be the inner side (in Figure 3, it is the upper side of the paper, in Figure 4, it is the left side of the paper, in Figure 5, it is the back side of the paper, and in Figures 6 and 7, it is the upper left side of the paper.) . Let the direction indicated by the arrow Ot be the front side (in Figure 3, it is the lower side of the paper, in Figure 4, it is the right side of the paper, in Figure 5, it is the front side of the paper, in Figures 6 and 7, it is the lower right side of the paper) .). Let the direction indicated by the arrow In and the arrow Ot be the width direction. Let the direction indicated by the arrow Us be one end side (the left side of the paper in Figures 3 and 5, the front side of the paper in Figure 4, and the lower left side of the paper in Figures 6 and 7.). Let the direction indicated by the arrow Ds be the other end side (the right side of the paper in Figures 3 and 5, the back side of the paper in Figure 4, and the upper right side of the paper in Figures 6 and 7.). Let the direction indicated by the arrow Us and the arrow Ds be the long side direction. These directions represent relative positional relationships and do not represent absolute positional relationships with respect to the direction of gravity.

Fig. 6 is an enlarged perspective view showing the feeding member. As shown in FIG. 6 , the feeding member 51 is a substantially rectangular parallelepiped extending in one direction, and extends in the longitudinal direction indicated by arrows Us and arrow Ds. This feeding member 51 is provided with an inclined surface 51A and a front surface 51B on the front side indicated by arrow Ot. The inclined surface 51A is an inclined flat surface and gradually inclines from the front side toward the back side indicated by the arrow In as it goes from the lower side indicated by the arrow Dw toward the upper side indicated by the arrow Up. The front surface 51B is a flat surface and extends in the up-and-down direction indicated by arrows Up and Dw. The inclined surface 51A and the front surface 51B are formed over the entire length of the feed member 51 in the longitudinal direction from an end 51C on one end side indicated by an arrow Us to an end 51D on the other end side indicated by an arrow Ds. The inclined surface 51A and the front surface 51B are arranged vertically adjacent to each other and connected in the vertical direction. In other words, the upper side of the front surface 51B is connected to the inclined surface 51A, and the lower side of the inclined surface 51A is connected to the front surface 51B.

The feeding member 51 is provided with a recessed portion 51a, a groove 51b, and a fastening hole 51p. The recessed portion 51 a is a substantially rectangular recessed portion that extends upward from the bottom surface 51E of the feeding member 51 and is recessed toward the back side from the front surface 51B of the feeding member 51 . The upper side of this recessed portion 51 a is curved in an arc shape, and the lower side is open to the bottom surface 51E of the feeding member 51 . In addition, the front side of the recessed portion 51 a opens on the front surface 51B of the feeding member 51 .

The groove 51b is a groove that extends in one direction, extends obliquely from the upper part of the recessed part 51a to the lower part of the inclined surface 51A, and is recessed toward the back side from the front surface 51B. That is, the front side of the groove 51b opens in the range from the upper part of the recessed part 51a to the slope 51A. This groove 51b communicates with the recessed part 51a. In addition, the groove 51b extends obliquely upward in the longitudinal direction of the feeding member 51 . When the other end side of the feeding member 51 indicated by the arrow Ds is set to 0°, the inclination angle θ of the groove 51 b is within an angle range of 15° to 25° toward the upper side indicated by the arrow Up (15°≤ θ≤25°), preferably about 20° (θ≈20°).

The fastening hole 51p is circular, and is configured so that fasteners Bt such as screws and bolts can be inserted. This fastening hole 51p penetrates from the front surface 51B of the feed member 51 to the back surface 51F on the back side. In the illustrated example, there are three fastening holes 51 p, and they are arranged at intervals in the longitudinal direction of the feeding member 51 . Thereby, the feeding member 51 can be fixed by screwing the fastener Bt into the fastening hole 51p (refer to FIG. 5).

Returning to FIG. 4 , the opposing member 52 is substantially rectangular parallelepiped like the feeding member 51 and extends in the longitudinal direction. This opposing member 52 is provided with a slope 52A and a back surface 52B on the back side. The inclined surface 52A is an inclined flat surface and gradually inclines from the inner side toward the front side as it goes from the lower side toward the upper side. The back surface 52B is a flat surface and extends in the up-down direction. The inclined surface 52A and the back surface 52B are formed over the entire length of the opposing member 52 in the longitudinal direction from one end to the other end (not shown). The inclined surface 52A and the back surface 52B are arranged vertically adjacent to each other and connected in the vertical direction. In other words, the upper side of the back surface 52B is connected to the slope 52A, and the lower side of the slope 52A is connected to the back surface 52B.

The feeding member 51 and the opposing member 52 have the same length in the longitudinal direction. Therefore, the inclined surface 51A of the feeding member 51 and the inclined surface 52A of the opposing member 52 have the same length in the longitudinal direction, and the front surface 51B of the feeding member 51 and the back surface 52B of the opposing member 52 have the same length in the longitudinal direction. The height H1 of the front surface 51B of the feeding member 51 is the same as the height H2 of the back surface 52B of the opposing member 52 (H1=H2) (see FIGS. 4 and 6 ). Thereby, when the front surface 51B of the feeding member 51 and the back surface 52B of the opposing member 52 are brought into contact with each other, the front surface 51B of the feeding member 51 and the back surface 52B of the opposing member 52 are in contact over the entire surface, and the feeding member The inclined surface 51A of 51 and the inclined surface 52A of the opposing member 52 are arranged to face each other in a V-shape that is open toward the upper side. That is, the inclined surface 51A of the transmission member 51 and the inclined surface 52A of the opposing member 52 form a V-shaped groove (see FIG. 4 ). This groove extends in the longitudinal direction of the feeding member 51 and the opposing member 52 .

As shown in FIGS. 3 and 4 , the feeding member 51 and the opposing member 52 are mounted on the conveyor body 21 of the first linear feeder 20 . At this time, the feeding member 51 and the opposing member 52 are arranged adjacent to each other on the back and front sides and connected in the width direction, and the front surface 51B of the feeding member 51 and the back surface 52B of the opposing member 52 are in contact with each other. Therefore, a V-shaped groove composed of the respective slopes 51A and 52A is formed between the feeding member 51 and the opposing member 52 . This groove extends in the conveying direction F and forms part of the conveying path 22 of the first linear feeder 20 . In other words, the inclined surface 51A of the feeding member 51 and the inclined surface 52A of the opposing member 52 constitute a part of the conveyance path 22 . Therefore, when the conveyance object CN is conveyed on the conveyance path 22, the conveyance object CN passes through the groove formed by the slope 51A and the slope 52A.

As shown in FIG. 6 , in this state, the introduction hole 50 a and the injection hole 50 b are formed between the feeding member 51 and the opposing member 52 . This introduction hole 50a is surrounded by the inner surface and the bottom surface of the recessed portion 51a of the feeding member 51 and the back surface 52B of the opposing member 52, and is configured to be airtight. The injection hole 50b is surrounded by the inner surface and the bottom surface of the groove 51b of the feed member 51 and the back surface 52B of the opposing member 52, and is configured to be airtight. The back surface 52B of the opposing member 52 corresponds to the surface that comes into contact with the feeding member.

This introduction hole 50a communicates with the injection hole 50b. Specifically, the upper end of the introduction hole 50a communicates with the lower end of the injection hole 50b, the lower end of the introduction hole 50a opens on the bottom surface 51E of the feed member 51, and the upper end of the injection hole 50b opens on the lower side of the slope 51A, that is, the conveyor The bottom of road 22 is open (refer to Figure 3). Therefore, when compressed air is introduced into the introduction hole 50 a from the bottom surface 51E of the feeding member 51 , the compressed air is supplied toward the injection hole 50 b through the introduction hole 50 a and is ejected from the bottom of the conveyance path 22 .

The injection hole 50b is narrower and more elongated than the introduction hole 50a. Therefore, the injection hole 50b can increase the flow rate of the compressed air injected into the introduction hole 50a. In addition, the injection hole 50b extends obliquely upward toward the conveyance direction F. The inclination angle of the injection hole 50b is the same as the inclination angle θ of the groove 51b. When the conveyance direction F (horizontal direction) is 0°, it is inclined upward in the range of 15° to 25°, and more preferably about 20°. °. In other words, the injection hole 50b extends downward from the bottom of the conveyance path 22 at an inclination angle ranging from 15° to 25° when the upstream side of the conveyance direction F is 0°. Therefore, the compressed air can be ejected from the bottom of the conveyance path 22 obliquely upward toward the conveyance direction F at an acute angle. This compressed air can prevent the normal posture of the conveyed object CN from being distorted, so that the conveyed object CN can be pushed toward the conveying direction F while maintaining the standard posture of the conveyed object CN.

The air supply unit has an air supply device such as a supply pipe, a hose, and a compressor (not shown). One end of the supply pipe is inserted into the introduction hole 50 a from the bottom surface 51E of the feed member 51 . The other end of the supply pipe is connected to the hose. This hose is connected to the air supply. Therefore, the introduction hole 50a, the supply pipe, the hose, and the air supply device are connected. That is, when the air supply device is driven, the compressed air is sequentially poured from the air supply device into the introduction hole 50a through the hose and the supply pipe, and is supplied from the introduction hole 50a to the injection hole 50b. This air supply device is configured to always supply compressed air. Thereby, compressed air is always injected from the injection hole 50b. In addition, a solenoid valve capable of adjusting the flow rate of compressed air may be provided between any of the supply pipes, hoses, and air supply devices. The air supply unit is equivalent to a concept including an introduction hole 50a, a supply pipe, a hose, an air supply device, and a solenoid valve.

Figure 7 is an enlarged perspective view of another feeding component. As shown in FIG. 7 , the other feeding member 61 is a substantially rectangular parallelepiped extending in the longitudinal direction and has the same dimensions as the feeding member 51 . The feed part 51 is provided with one set of recesses 51a and grooves 51b, while the other feed part 61 is provided with two sets of recesses 61a, 61a' and grooves 61b, 61b'. One set of recessed portions 61a and grooves 61b and the other set of recessed portions 61a′ and grooves 61b′ are provided on the front side of the other feeding member 61 at intervals in the longitudinal direction. The recessed portions 61a, 61a′ of the other feeding member 61 are the same as the recessed portion 51a of the feeding member 51, and the grooves 61b, 61b′ of the other feeding member 61 are the same as the groove 51b of the feeding member 51. The same parts as those of the feeding part 51 in the other feeding part 61 are denoted by the same reference numerals, and description thereof is omitted.

Like the feeding member 51 , this other feeding member 61 is mounted on the conveying body 21 of the first linear feeder 20 in a state where its front surface 61B is in contact with the back surface 52B of the opposing member 52 . At this time, two sets of introduction holes 60a, 60a' and injection holes 60b, 60b' are formed between the other feeding member 61 and the opposing member 52. The introduction hole 60a and the injection hole 60b of one set are spaced apart from the introduction hole 60a' and the injection hole 60b' of the other set along the conveyance direction F of the 1st linear feeder 20. The introduction holes 60a, 60a' are the same as the introduction hole 50a, and the injection holes 60b, 60b' are the same as the injection hole 50b.

In this state, the slope 61A of the other feed member 61 and the slope 52A of the counter member 52 are arranged to face each other in a V-shape, forming a V-shaped groove. This groove forms part of the conveying path 22′ of the first linear feeder 20. At the bottom of this tank, that is, at the bottom of the conveyance path 22', two injection holes 60b, 60b' are opened at intervals along the conveyance direction F. This allows compressed air to be blown twice to the same conveyed object CN.

Fig. 8 is an explanatory diagram when rotating a conveyed object. As shown in FIG. 8 , in the vibration conveyor 10 , the conveyed objects CN are continuously conveyed on the conveyance path. At this time, if there is no gap before and after the conveyed object CN, the conveyed object CN cannot be rotated. Here, the standard posture of the conveyed object CN is an posture in which the longitudinal direction of the conveyed object CN extends along the conveying direction F (horizontal direction), and the defective posture of the conveyed object CN is one in which the longitudinal direction of the conveyed object CN is orthogonal to the conveying direction F. The posture of extending in the direction (up and down direction). In FIG. 8 , among the three conveyed objects CN, the postures of the two conveyed objects CN and CN on both sides are standard postures, and the posture of the conveyed object CN in the middle is a defective posture.

When rotating the conveyed object CN from the defective posture to the standard posture, let the length of the conveyed object CN in the longitudinal direction be L, let the inclination angle of the conveyed object CN be αt, and let the distance between the front and rear gaps of the conveyed object CN be are Fr and Bk, then the distances Fr and Bk become L/2·sinαt (Fr=L/2·sinαt, Bk=L/2·sinαt). The distance Fr of the front gap of the conveyed object CN is the same as the distance Bk of the rear gap of the conveyed object CN (Fr=Bk). If the distances Fr and Bk between the front and rear gaps are smaller than L/2·sinαt, the conveyed object CN will collide with the conveyed objects CN and CN connected to the front and rear, so the conveyed object CN cannot be rotated. Therefore, the distances Fr and Bk between the front and rear gaps of the conveyed object CN must be larger than L/2·sinαt (Fr≥L/2·sinαt, Bk≥L/2·sinαt). Here, the inclination angle αt of the conveyed object CN changes with time t. Therefore, the distances Fr and Bk of the front and rear gaps of the conveyed object CN change with time t.

More specifically, when the conveyed object CN is rotated from the bad posture to the standard posture, the inclination angle αt of the conveyed object CN changes from 0° to 90°. When the inclination angle αt of the conveyed object CN is 0°, the distances Fr and Bk between the front and rear gaps of the conveyed object CN are 0 (Fr=0, Bk=0). When the inclination angle αt of the conveyed object CN is 30°, the distances Fr and Br between the front and rear gaps of the conveyed object CN become L/4 (Fr=L/4, Bk=L/4). When the inclination angle αt of the conveyed object CN is 45°, the distances Fr and Bk of the front and rear gaps of the conveyed object CN become √2/4·L (Fr=√2/4·L, Bk=√2/4·L) . When the inclination angle αt of the conveyed object CN is 60°, the distances Fr and Bk between the front and rear gaps of the conveyed object CN become √3/4·L (Fr=√3/4·L, Bk=√3/4·L) . When the inclination angle αt of the conveyed object CN is 90°, the distances Fr and Bk between the front and rear gaps of the conveyed object CN become L/2 (Fr=L/2, Bk=L/2). Therefore, as the inclination angle αt of the conveyed object CN gradually changes from 0° to 90°, the distances Fr and Bk of the front and rear gaps of the conveyed object CN gradually become larger. Therefore, in order to rotate the conveyed object CN smoothly, the distances Fr and Br of the front and rear gaps of the conveyed object CN need to be increased as the conveyed object CN rotates around the center Q. In other words, the front-to-back distance of the conveyed object CN needs to be expanded as the conveyed object CN rotates around the center Q.

(a) to (c) in FIG. 9 are explanatory diagrams showing a state in which a conveyed object in a standard posture is conveyed by the posture changing device of this embodiment. As shown in (a) to (c) in FIG. 9 , in a state where three conveyed objects CN1 , CN2 , and CN3 are continuously conveyed on the conveying path 22 of the vibrating conveyor 10 , when the conveyed object CN1 in the standard posture reaches the injection When the object CN1 is above the opening of the hole 50b ((a) in Figure 9), the conveyed object CN1 flies up from the conveying path 22 obliquely upward in the conveying direction F ((b) in Figure 9) under the action of both the vibration V and the compressed air Ar. )), and falls onto the conveyor path 22 while maintaining the standard posture ((c) in Figure 9). Thereby, since both the vibration V and the compressed air Ar transmitted by the vibrating conveying device 10 push the conveyed object CN1 toward the conveying direction F, the distance between the conveyed object CN1 and the subsequent conveyed object CN2 can be enlarged. In FIG. 9 , the distance between the conveyed object CN1 and the conveyed object CN2 changes from the distance Fr1 to the distance Fr2. From the perspective of the conveyed object CN2 in the middle among the three conveyed objects CN1, CN2, and CN3, the distance of the front gap in the conveying direction of the conveyed object CN2 becomes larger.

(a) to (c) in FIG. 10 are explanatory diagrams showing a state in which the posture of a conveyed object with a bad posture is changed by the posture changing device of this embodiment.

The posture in which the longitudinal direction extends along the conveying direction F is regarded as the standard posture, and the longitudinal direction is orthogonal to the conveying direction F. When the posture extending in the direction is a bad posture, let the length of the longitudinal direction of the conveyed object CN be L and the inclination angle of the conveyed object CN be αt, so that the conveyed objects connected in the conveying direction F Compressed air Ar is injected from the injection hole 50b in such a manner that the distance Fr and Bk between CN is larger than L/2·sinαt, so that the compressed air Ar can be used to expand the distance Fr and Bk between the conveyed objects CN connected in the conveying direction F. The conveyed object CN with a bad posture is rotated without hindrance.

In this embodiment, the injection hole 50b extends from the lower side of the conveyance path 22 to the bottom of the conveyance path 22 at an inclination angle θ within an angle range of 15° to 25° from bottom to upward when the conveyance direction F is 0°. , whereby the compressed air Ar can be injected from the bottom of the conveyance path 22 at an inclination angle θ within an angle range of 15° to 25° when the conveyance direction F is 0°, so the conveyed object CN will not be blown away. To the extent necessary, the conveyed object CN in the standard posture can be pushed toward the conveying direction F while maintaining the standard posture of the conveyed object CN, and the conveyed object CN in an abnormal posture can be rotated.
