Description

Parts supply device

The present invention relates to a component supply apparatus in which a component housed in a storage container is lifted by a lift member and transferred to a transfer unit, and the component is supplied to a target location by the transfer unit.

In Japanese Patent Laid-Open No. 2002-362951, a part stored in the bottom of a container is lifted by a lift bar and transferred to a standby container. When the number of parts in the standby container reaches a predetermined number, an operator A technique for opening a lid and taking out a component is disclosed.

JP 2002-362951 A

In the technique disclosed in the above-mentioned patent document, the lift rod has a double structure in which the inner rod is inserted into the hollow tube, and when raising the part, the inner rod is in a position retracted from the hollow tube. Yes, the inner rod advances at the fully raised position, and the part falls into the standby container.

With such a structure, there is a problem that only one part rises when the lift bar is raised once, and the conveyance efficiency is not improved. Moreover, since it is a double-structure lift bar, the mechanism for operating it is complicated, which is disadvantageous for making the apparatus compact.

The present invention has been provided to solve the above-described problems, and an object thereof is to provide a component supply device that can efficiently transport a plurality of components and simplify the device structure.

According to the first aspect of the present invention, a lower part is formed in the vicinity of the end of the bottom member of the storage container, and a lift member that raises a part waiting on the lower part is raised and lowered along the inner wall of the storage container. Arranged in a state where it can be moved, the part lifted by the lift member is transferred and a transfer means for transferring the part to the destination is provided, and the part where the part is transferred to the transfer means is set near the lift position of the lift member A component supply device is provided.

A lift member is formed in a state in which a low part is formed in the vicinity of the end of the bottom member of the storage container, and a lift member that raises a part waiting on the low part can be moved up and down along the inner wall of the storage container. Can be moved up and down along the end of the storage container to increase the capacity of the storage container as much as possible. That is, since the low part is located in the vicinity of the end portion of the bottom member, the lift member can also be arranged close to the end portion of the storage container, and accordingly, expansion of the component accommodation space is realized.

Since the lift member moves up and down along the inner wall of the storage container, the components placed on the upper surface of the lift member rub against the inner wall or rise with a slight gap between them. For this reason, the state where the component is placed on the upper surface of the lift member is maintained, and the component is reliably transferred to the transfer means, and the operational reliability of the apparatus is improved. Then, by setting the parts placement surface of the lift member large, a large number of parts can be transferred in a single ascending operation, and the conveyance efficiency can be improved.

In addition, since the lift member moves up and down along the inner wall of the storage container, it is possible to reliably lift the parts waiting in the low part, and the lift member's lift resistance that rises by dividing the parts group is increased. As a result, the lift driving force of the lift member can be reduced. For example, if the lift member is moved up and down by an air cylinder, it is effective for reducing the size of the air cylinder.

Since the part where the parts are transferred to the transfer means is set in the vicinity of the lift position of the lift member, the parts can be reliably transferred to the transfer means. At the same time, an elongate transfer means such as a linear feeder can be arranged along the side surface of the storage container, which is effective for making the entire apparatus compact.

According to a second aspect of the present invention, there is provided a component supply apparatus in which the transfer means is constituted by an elongate rectilinear feeder, and the rectilinear feeder is disposed along a straight lateral surface of the storage container.

組み合わせ By combining the elongated transfer means and the straight lateral surface of the storage container, the integration of the storage container and the transfer means can be achieved with a minimum space, which is effective for making the apparatus compact.

According to the third aspect of the present invention, a partition control member for dividing the storage container into a first storage space and a second storage space is provided, and the first storage space stores a large amount of parts replenished from the outside. The second storage space is a standby space in which the parts raised by the lift member are made smaller than the large amount of parts in the first storage space, and between the lower end portion of the partition control member and the bottom member, A component supply device is provided in which a part that goes from the first storage space toward the second storage space is intertwined with each other and a passage portion that limits the amount of movement of the component to the second storage space is formed.

For example, parts that are angular or jagged like male screws, such as bolts with washers or projection nuts with welding protrusions, can be entangled or stuck together when they pass through the passage. As a result, smooth passage becomes difficult. Since such a passage restriction is imposed on the passage portion, the amount of components stagnating in the second storage space is significantly smaller than the amount of components stored in the first storage space. The second storage space functions as a standby space for such a small amount of parts. For this reason, the number of parts that can be raised by the lift member is not excessive, and the power required to raise the lift member is reduced. Can be made. For example, when the lift member is raised by an air cylinder, the air cylinder can be downsized and the amount of compressed air to be used can be reduced, which is economical.

In other words, for example, in the case of a component stored in a large amount like the first storage space, it is necessary to overcome the resistance due to the weight of the large amount of components or the entanglement between the components, and push up the lift member. Since a small amount of parts are waiting in the space, the lift resistance of the lift member is reduced.

On the other hand, in the first storage space, the function of storing a large amount of parts is surely fulfilled by the passage restriction in the passage portion, and even if the storage space of the first storage space is enlarged, the second storage space is excessive. Adverse effects such as supply can be avoided, and the part supply interval to the first storage space can be extended, which is advantageous in terms of supply control of parts.

As described above, it is possible to increase the amount of parts stored in the first storage space and appropriately reduce the amount of parts waiting in the second storage space.

According to a fourth aspect of the present invention, there is provided a component supply apparatus configured such that the passage portion is formed at a location close to the lift member, and a component that has passed through the passage portion is guided toward the lift member. .

Since the passage portion is formed at a location close to the lift member, the parts whose movement amount is limited in the passage portion are guided toward the lift member. That is, since the number of passages is limited at the passage part and moves toward the lift member, the number of parts lifted by the lift member does not become excessive, and the lifting load of the lift member is reduced.

According to the fifth aspect of the present invention, an elongated guide inclined surface toward the low part is formed in a part of the inclined surface of the bottom member of the second storage space, and the guide inclined surface is viewed in the width direction. The component supply device is configured in a horizontal state or in an inclined state so that the end on the partition control member side becomes higher and lowers toward the lower part side. Is done.

The parts stored in the second storage space are guided to the low part by sliding down the guiding inclined surface. This is because a part of the parts stored in the entire second storage space is guided to a low part through an elongated guide inclined surface without stagnation. After that, it moves to the low part. In other words, among the parts in the entire second storage space, the parts on the guiding inclined surface slide down the elongated inclined surface toward the low part, so that the parts in the second storing space reliably pass through the guiding inclined surface in the low part. That is, the parts are transferred onto the lift member, and the parts are reliably supplied to the target place by the lift and the operation of the transfer means.

Since the guide inclined surface is horizontal when viewed in the width direction, the parts existing on the guide inclined surface are less likely to fall from the guide inclined surface, and the number of parts heading to the lower part is further increased. Along with this, the number of parts raised by the lift member increases, and the number of transports in the transport means can be secured without shortage.

Furthermore, since the guide inclined surface is configured in a state of being inclined so that the end on the partition control member side becomes higher, in the case where the guide inclined surface is arranged along the inner wall of the storage container, The parts placed on the guiding inclined surface will slide down while rubbing the inner wall of the storage container, which makes it difficult for the parts on the guiding inclined surface to fall from the guiding inclined surface and increase the number of parts toward the low part. It is suitable for.

When the transfer posture of the parts is abnormal or the size of the parts is too large or too small, the parts are configured to fall into the second storage space from the sorting member arranged in the transfer means. Sometimes. When such a fall configuration is adopted, the fallen parts are preferentially transferred by the lift member by receiving the fallen parts with the guide inclined surface, and the parts storage amount in the second storage space As a result, the parts can be supplied smoothly without excessively increasing the amount of the current.

Since the parts transferred onto the lift member are in various postures, all the parts transferred to the transfer means are not conveyed in a normal posture. For this reason, a part with an abnormal posture falls from the sorting member to the second storage space with a certain probability. The parts that have fallen in this manner are preferentially guided to the low part through the guide inclined surface, whereby the amount of parts stored in the second storage space can be optimized.

Next, a mode for carrying out the component supply apparatus of the present invention will be described.

1 to 8 show a first embodiment of the present invention.

First, the target parts will be explained.

18A, 18B and 18C show the target parts. FIG. 18A shows a bolt with a washer. The bolt 1 includes a shaft portion 2 and a head portion 3. The head 3 is composed of a hexagonal portion 3A and a washer 3B having a diameter larger than that of the shaft portion 2. The washer 3 B is assembled to the small diameter portion 5 of the shaft portion 2, and is allowed to move loosely without coming off the shaft portion 2.

18B, the head 3 is constituted by a hexagonal portion 3A and a flange 6 molded integrally with the hexagonal portion 3A. In addition, the external thread is processed in the axial part 2, the external thread is shown only in FIG. 18A and 18B, and illustration of the external thread is abbreviate | omitted in other figures.

FIG. 18C shows a shaft-shaped component with a head constituted by a short cylindrical head 7 and a shaft portion 8 without a male screw. The three types of parts are all made of iron. Other than these components, projection nuts that are square and have welding projections formed at the four corners can be targeted. Such a projection nut is also a component provided with an angular projection-shaped portion like the washer-attached bolt.

There are various target parts as described above, but here, the bolt 1 with a washer shown in FIG. 18A.

Next, the storage container will be described.

The storage container 9 that accommodates a large number of bolts 1 has a square box shape when viewed from directly above. Stainless

steel wall plates

12, 13, 14, and 15 are welded to four sides of the bottom member 10 made of a stainless steel square plate material.

A low part 16 is formed in the vicinity of the end of the bottom member 10 of the storage container 9. This low part 16 is arranged in the upper right of FIG. For this purpose, a first inclined surface 17 that decreases toward the right in FIG. 1 and a second inclined surface 18 that decreases toward the upper side in FIG. 1 are formed. Since the first inclined surface 17 and the second inclined surface 18 are steeply inclined from the middle, a broken line 19 appears. By combining the first inclined surface 17 and the second inclined surface 18, the low portion 16 is formed in the corner portion of the square storage container 9 formed by the wall plate 12 and the wall plate 15.

Although not shown, it is desirable to provide an opening / closing lid on the storage container 9 so that impurities such as iron scraps are not mixed into the bolt 1.

Next, the lift member will be described.

A square passage hole 20 is opened at the upper right corner of the bottom member 10. The lift member 22 is constituted by a member formed by elongating a thick plate material, and is lifted and lowered in a substantially vertical direction. A mounting surface 23 on which the bolt 1 is mounted is formed on the upper surface of the lift member 22. The mounting surface 23 may be a horizontal surface, but is a flat inclined surface that lowers the wall plate 15 side in order to prevent the bolt 1 from spilling down. This inclination angle θ is shown in FIG. The lift member 22 is made of stainless steel, which is a nonmagnetic material.

When the lift member 22 is positioned at the lowest position, the mounting surface 23 is in a state of being continuous with the inclined bottom member 10 (second inclined surface 18) as shown in FIGS. 3 and 5A. . In this way, the bolt 1 that has moved to the low part 16 is waiting on the placement surface 23.

The lift member 22 is arranged in a state where it can be moved up and down along the inner wall of the storage container 9. Here, the lift member 22 moves up and down along the inner surfaces of the wall plate 15 and the wall plate 12. Ascending and descending along the inner surfaces of the wall plate 15 and the wall plate 12 means that the outer surface of the lift member 22 moves up and down while rubbing against the inner surfaces of the wall plate 15 and the wall plate 12, or the outer surface of the lift member 22 is the wall. This means that the plate 15 and the wall plate 12 are moved up and down with a slight gap between them. The number of bolts 1 to be placed is determined by the width of the placement surface 23. In the case of illustration, there are three.

The air cylinder 24 for raising and lowering the lift member 22 is fixed to the wall plate 12, and the piston rod 26 of the air cylinder 24 is coupled to the support plate 25 coupled to the lower end of the lift member 22. The lift member 22 moves up and down as the air cylinder 24 outputs advancing and retracting.

Next, the entanglement between bolts will be described.

FIG. 6A shows an intertwined state between the bolts. When a large number of bolts 1 are accommodated in the storage container 9, the corners of the end of the shaft portion 2 bite into the threads of the bolts 1, the flanges 6 overlap each other, and the peaks are aligned with the valleys of the threads. Since various entanglements and struts occur due to factors such as the action of the weight of the bolt 1 and the like, even if the inclination of the first inclined surface 17 or the second inclined surface 18 is given, It may be impossible to slide down.

Such a phenomenon sometimes occurs due to the above-described entanglement and tension, and once it occurs, it becomes a group of parts in which a large number of bolts 1 are intertwined and restrained. In this state, as shown in FIG. 6B, an air space 27 where the bolt 1 does not exist is formed, and a phenomenon that the bolt 1 does not stand by on the mounting surface 23 of the lift member 22 occurs, and the bolt 1 is not transferred. It becomes possible.

In order to prevent such a so-called locked phenomenon, a suction means for sucking a part of the part group in which the bolts 1 are entangled with each other to the low part 16 side or an extrusion for extruding a part of the part group to the low part 16 side. Means are provided.

FIG. 7 shows an example of suction means. A permanent magnet 28 is embedded in the lift member 22, and its height position is a position at which the bolt 1 can be attracted to the low portion 16 when the lift member 22 is raised most. That is, when the lift member 22 is positioned at the uppermost position, the permanent magnet 28 stands by near the second inclined surface 18.

When the permanent magnet 28 stops at the position shown in FIG. 7, the bolt 1 in a restrained state is attracted toward the permanent magnet 28. The part is unraveled. Subsequently, the unwinding operation is continuously expanded in a chained manner, and the range of the unconstrained state in the region near the permanent magnet 28 is widened. In this way, a part of the entangled parts group is sucked to the low part 16 side, and the bolt 1 is made to wait by partial unraveling, and further, the unraveled range is expanded and the lift member 22 is emptied. Reliable transfer without operation is realized.

It should be noted that the permanent magnet 28 can be arranged outside the wall plate 15 as indicated by a two-dot chain line in FIG.

On the other hand, FIG. 8 shows an example of the extrusion means. An air cylinder 55 is attached to the outside of the storage container 9, and an extrusion member 56 that advances and retreats by the air cylinder 55 is disposed so as to protrude into the storage container 9. Here, the pushing member 56 is formed by a piston rod of the air cylinder 55. Although not shown, it is also possible to weld an extrusion plate to the tip of the extrusion member 56 and apply an extrusion force to a large number of bolts 1 on a wide surface of the plate.

When the pushing member 56 is forcibly advanced toward the parts group in a restrained state, the entanglement and tension between the bolts are broken, and the bolt restraint on the extending direction side of the pushing member 56 is released. By such unraveling, the first inclined surface 17 is slid down while the bolt 1 is forcibly pushed out, the bolt 1 is made to reach the area of the air space 27, and the standby of the bolt 1 on the mounting surface 23 is made.

Next, the transfer means will be described.

The transfer means is for transferring the bolt 1 lifted by the lift member 22 to the target location. For example, the bolt 1 is transferred to the target location with a predetermined posture. As this transfer means, various types such as those for sliding down the bolt 1 and those for transferring using vibration can be adopted. Here, the latter is a vibration type linear feeder.

A straight feeder which is a transport means is indicated by reference numeral 29. The rectilinear feeder 29 is arranged along the outer side surface of the wall plate 15 whose flat direction is flat and straight. In the rectilinear feeder 29, a receiving member 30 to which the bolt 1 is transferred, a suspending member 31 continuing to the receiving member 30, and a selecting member 32 continuing to the suspending member 31 are linearly arranged. Then, the bolt 1 is supplied from the sorting member 32 to the target location, or is supplied to the target location via the suspension member 33 similar to the suspension member 31.

As shown in FIG. 4, the receiving member 30, the hanging member 31, the sorting member 32 and the hanging member 33 are coupled to the elongated base member 35 through bolts or the like via

support members

36, 37, 38 and 39. It is. The base member 35 is disposed above the stationary member 41 by two obliquely disposed leaf springs 40, and the electromagnet 42 imparts vertical vibration to the base member 35, thereby feeding leftward in FIG. An output component is formed and bolt transfer is performed.

In order to concentrate the bolt 1 at the center of the receiving member 30, an inclined surface 43 with a lowered center is formed on the left and right to form a shallow V-shaped cross-section 44. The place where the bolt 1 is transferred, that is, the V-shaped cross section 44 is arranged in the vicinity of the lifted position of the lift member 22. As shown in FIGS. 3, 5 A, and 7, when the lift member 22 is positioned at the uppermost position, the placement surface 23 and the V-shaped cross-section 44 are adjacent to each other with the wall plate 15 therebetween.

As shown in FIG. 5B, the suspension member 31 is supported on a sliding surface 46 of a pair of parallel rail members 45 in a state where the lower surface of the washer 3B, that is, the lower surface of the head 3 can slide. And the axial part 2 passes between the rail members 45 in a suspended state. The lower portions of the rail members 45 are integrated by a connecting member 47.

Next, the fall structure part will be described.

In the parts supply process place, normal bolt 1A of normal length, overlong bolt 1B that is too long, overshort bolt 1C that is too short, etc. may be transported in the vicinity, for some reason, for example, An operator may mistakenly mix the excessive bolt 1B and the excessive bolt 1C into the normal bolt 1A. The sorting member 32 is arranged in a state of being continuous with the suspension member 31 in preparation for such abnormal mixing. Further, if the normal bolt 1A is turned upside down or is not properly suspended, it may be transported in an abnormal posture. In such a case, it is necessary to eliminate the normal bolt 1A. is there.

This selection member 32 is a core member, and a falling structure portion of a shaft-shaped component with a head is formed.

The sorting member 32 is a structural part that causes the

bolts

1B and 1C having an abnormal length to fall into the storage container 9 and the normal bolt 1A having an abnormal posture to fall, and as shown in FIGS. 5C, 5D, and 5E. In addition, the left side of the sorting member 32 is opened. This opening is made toward the open space 48. At the same time, a notch 15 A is provided in the upper part of the wall plate 15 so that the abnormally long bolts 1 B and 1 C can fall into the storage container 9. As described above, when the length of the bolt 1 conveyed in a suspended state by the rail member 45 is abnormal, the abnormal component is removed from the rail member 45 by falling.

As shown in FIG. 5C, a flat first sliding surface 32A on which the lower surface of the head 3 (the lower surface of the washer 3B) slides, and a flat second sliding surface 32B on which the lower end portion (lower end surface) of the shaft portion 2 slides. The vertical distance between the sliding

surfaces

32A and 32B is the same as the length of the shaft portion 2. And while the central axis of the shaft part 2 passes through the substantially central part of the second sliding surface 32B, the first sliding surface 32A is shifted to the side inclined from the central axis of the shaft part 2. It is arranged in. By doing so, the lower surface of the head 3 and the lower end of the shaft portion 2 simultaneously slide on the first sliding surface 32A and the second sliding surface 32B, respectively.

Then, the abnormally

long bolts

1B and 1C fall down in the direction indicated by the arrows in FIGS. 5D and 5E. On the other hand, the sorting member 32 is arranged in a posture inclined to the side opposite to the falling direction. That is, the upper side of the sorting member 32 is inclined rightward with respect to the vertical line OO.

The normal bolt 1A is supported so that the lower surface of the head 3 and the lower end of the shaft portion 2 can simultaneously slide on the first sliding surface 32A and the second sliding surface 32B, respectively, as shown in FIG. 5C. In a stable state as if leaning, it is transferred as it is and transferred to the suspension member 33.

As described above, since the lower surface of the head 3 and the lower end of the shaft portion 2 are simultaneously sliding on the first sliding surface 32A and the second sliding surface 32B, the vibration of the rectilinear feeder 29 is applied to the normal bolt 1A. However, stable transfer can be performed without falling.

When the excessively long bolt 1B is transferred to the sorting member 32, the head 3 is placed at a position floating from the first sliding surface 32A, so that the standing state of the bolt 1B becomes unstable, and vibration is added thereto. Then fall down as if falling down to the arrow line. Further, the upper side of the excessively long bolt 1B is slightly inclined to the right side of the vertical line OO, but falls due to the above unstable state and vibration. It is also possible to make the overhanging bolt 1B slightly tilted to the left side of the vertical line OO so that the sorting member 32 is slightly tilted so that it can easily fall.

As shown in FIG. 5D, the excessively long bolt 1 B becomes unstable because the outer peripheral portion of the head 3 comes into contact with the upper portion of the sorting member 32, and the vibration is also generated from the contact portion. This is because there is a space between the head 3 and the first sliding surface 32A.

When the lower end portion of the shaft portion 2 of the excessively long bolt 1B is received by the second sliding surface 32B and the head 3 is lifted from the first sliding surface 32A, the conveying force acts on the excessively long bolt 1B. The head 3 is inclined rearward in the conveying direction, the corner of the head 3 is received by the first sliding surface 32A, and the corner of the lower end of the shaft portion 2 is in contact with the second sliding surface 32B. The corner portion of the portion 3 may move so as to drag the first sliding surface 32A. That is, the excessively long bolt 1 B is inclined to the rear side in the conveying direction, and the lower end portion of the shaft portion 2 is in an inclined state preceding the head portion 3. Such an inclined state is not a state in which the first long sliding surface 32A and the second sliding surface 32B are slidable on the lower surface of the head and the lower end of the shaft portion of the excessively long bolt 1B, respectively. Therefore, the support stability of the excessively long bolt 1B cannot be maintained and falls from the sorting member 32.

In the inclined state as described above, the corner portion of the head 3 hits the opening-side corner portion 11 on the shaft portion 2 side of the first sliding surface 32A, so that the force toward the opening side of the sorting member 32 acts on the head 3. There is a phenomenon that. Such a force component causes a reliable fall.

In some cases, the inclination direction of the excessively long bolt 1B in the conveying direction is opposite to the above direction. Also in this case, since the corner portion of the head 3 hits the opening-side corner portion 11, the force toward the opening side of the sorting member 32 acts on the head 3, and the force component surely falls.

When the overshort bolt 1C is transferred to the sorting member 32, the head 3 is placed at a position lower than the first sliding surface 32A, so that the standing state of the bolt 1C becomes unstable, and vibration is added thereto. Then fall down as if falling down to the arrow line. Further, since the upper side of the overshort bolt 1C is slightly inclined to the left side of the vertical line OO, it is easy to fall. As shown in FIG. 5E, the excessively short bolt 1C becomes unstable because the outer peripheral portion of the head 3 comes into contact with the upper portion 32C of the sorting member 32 and is tilted further to the left than the vertical direction. It is to become a posture.

When the length of the normal bolt 1A is changed, the sorting member 32 is removed from the support member 38 and replaced with a sorting member 32 having a different interval length between the first sliding surface 32A and the second sliding surface 32B. By doing so, it is possible to flexibly cope with normal bolts 1A having different lengths.

For example, when the receiving member 30 is coupled to the base member 35, although not illustrated, a fixing bolt inserted from the lower side of the base member 35 may be screwed into the receiving member 30 through the support member 36. There are two ways. Similarly, since the selection member 32 can be attached and detached with the same fixing bolt as that of the receiving member 30, it is possible to easily cope with the case where the length of the normal bolt 1A is changed.

In order to smoothly transfer the bolt 1 from the suspension member 31 to the selection member 32, the rail member 45 on the wall plate 15 side has a length L (see FIG. 1) longer than the rail member 45 on the other side. Is set longer by As shown in FIG. 5B, since the bolt 1 that has been transferred in a suspended state has a difference in length L, the rail member 45 on the side far from the wall plate 15 comes first when the bolt 1 is reached. I am interrupted. For this reason, the bolt 1 inclines so that the wall board 15 side may become high. Due to such an inclination, transfer is performed in a state along the sorting member 32 inclined outward. That is, as shown in FIG. 5C, the normal bolt 1A smoothly moves to the sorting member 32.

If for some reason the bolt 1 is transported sideways on the suspension member 31 or the head 3 is transported with the head 3 facing down, the bolt 1 is not properly suspended. It falls from 31 to the sorting member 32 side and collides with a part of the sorting member 32. As a result, the bolt 1 is repelled and falls into the storage container 9.

Thus, if the bolt posture on the suspension member 31 is abnormal or the length of the bolt is too long or too short, they all fall into the storage container 9 and are in the state shown in FIG. 5C. Only the normal bolt 1A passes, and the abnormal bolt can be reliably removed. In other words, as shown in FIG. 5C, the lower surface of the head 3 slides on the first sliding surface 32A, and the lower end of the shaft portion 2 slides on the second sliding surface 32B. The normal bolt 1A is allowed to pass only when it is present.

Next, the configuration after the sorting member will be described.

After the sorting member 32, it is put in a receiving box or transferred to a hanging member 33 as shown. Here, a predetermined number of bolts are passed from the suspension member 33 by the counting unit 49, accumulated in the standby box 50, and the lid of the box 50 is opened to take out the predetermined number of bolts 1.

There are various configuration examples of the counting unit 49. Here, this is a type in which the pair of regulating

members

52 and 54 are advanced and retracted. The restricting member 52 that advances and retreats with the air cylinder 51 advances to stop the first bolt 1, and the restricting member 54 that advances and retreats with the air cylinder 53 stands by at the retracted position. When the restricting member 54 advances to stop the movement of the second bolt 1 and then the restricting member 52 moves backward, only the first bolt 1 falls into the standby box 50.

After that, when the regulating member 52 retreats and the regulating member 54 moves backward at the same time, the second bolt 1 is stopped at the first position, and the second bolt falls in the above order. Made.

Protective plates

21 and 34 are provided to prevent the bolt 1 from falling from the linear feeder 29 to the outside. The protection plate 21 has an elongated L shape when seen in a plan view, and is fixed to the end surface of the receiving member 30 by bolting or the like. Further, the protection plate 34 is fixed to the rear surface of the sorting member 32 by bolting or the like.

Next, the transfer behavior of the bolt will be described.

As shown in FIGS. 1, 2, 3, and 5 A, when the lift member 22 is positioned at the lowest position by the operation of the air cylinder 24, a plurality of bolts 1 are mounted on the lower portion 16 including the mounting surface 23. Is in a waiting state. When the lift member 22 rises in this state, the bolt 1 on the placement surface 23 rises while rubbing the inner surface (inner wall) of the wall plate 15, and the placement surface 23 is adjacent to the V-shaped cross-section 44. Stop.

Since the mounting surface 23 is lowered on the V-shaped cross section 44 side, the bolt 1 passes through the upper end of the wall plate 15 and is transferred onto the V-shaped cross section 44.

As shown in FIG. 5A, the bolt 1 has various postures on the V-shaped cross-section 44, such as sideways, a handstand with the head 3 on the lower side, and a slanted state. . When these bolts 1 are transferred on the V-shaped cross-section 44 by vibration, the bolts 1 are placed along the valleys of the V-shaped cross-section 44. In such a state, when the shaft portion 2 enters the rail member 45 with its own weight, the lower surface of the head 3 is received by the sliding surface 46, and the bolt 1 is suspended.

In such a neck hanging state, the hanging member 31 is moved and transferred to the sorting member 32, the normal bolt 1A is transferred in the state shown in FIG. 5C, and the excessively long bolt 1B and the excessively short bolt 1C are transferred to FIGS. 5D and 5E. Fall down toward the arrow as shown. In this way, only the normal bolt 1A passes through the counting unit 49 and is sent to the standby box 50.

It should be noted that, instead of the various air cylinders described above, an electric motor that outputs and retreats can be employed. It is also possible to replace the permanent magnet with an electromagnet.

The above-described advance / retreat operation of the lift member and the operation of the counting unit can be easily performed by a generally adopted control method. A predetermined operation can be ensured by combining an air switching valve that operates with a signal from the control device or the sequence circuit, a sensor that emits a signal at a predetermined position of the air cylinder, and transmits the signal to the control device.

The operational effects of the first embodiment described above are as follows.

The operational effects related to the lift of the low-part parts are as follows.

A low portion 16 is formed in the vicinity of the end of the bottom member 10 of the storage container 9, and a lift member 22 that raises the bolt 1 waiting in the low portion 16 is arranged in a state where it can be moved up and down along the inner wall of the storage container 9. Therefore, the lift member 22 can be moved up and down along the end of the storage container 9 to increase the component capacity of the storage container 9 as much as possible. That is, since the low part 16 is located in the vicinity of the end of the bottom member 10, the lift member 22 can also be arranged close to the end of the storage container 9, and accordingly, the component storage space can be expanded. To do.

Since the lift member 22 moves up and down along the inner wall of the storage container 9, the bolt 1 placed on the mounting surface 23, which is the upper surface of the lift member 22, rises while rubbing the inner wall. For this reason, the state in which the volt | bolt 1 was mounted in the mounting surface 23 of the lift member 22 is maintained, and the volt | bolt 1 is reliably transferred to the linear feeder 29 which is a transfer means, and the operation | movement reliability as an apparatus improves. And by setting the parts mounting surface of the lift member 22 large, a large number of bolts 1 can be transferred by a single ascending operation, and the conveyance efficiency can be improved.

Further, since the lift member 22 is moved up and down along the inner wall of the storage container 9, the bolt 1 waiting in the low part 16 can be reliably lifted, and the lift member is lifted so as to separate the parts group. Therefore, the lifting resistance of the lift member 22 can be reduced. For example, if the lift member 22 is moved up and down by an air cylinder, it is effective for reducing the size of the air cylinder.

Since the receiving member 30 on which the bolt 1 is transferred to the linear feeder 29 is set in the vicinity of the lift position of the lift member 22, the bolt can be transferred to the linear feeder 29 reliably. At the same time, since the elongate transfer means such as the rectilinear feeder 29 can be arranged along the side surface of the storage container 9, it is effective for making the entire apparatus compact.

The lift member 22 moves up and down at the corner portion of the rectangular storage container 9, that is, the corner portion formed by the wall plate 12 and the wall plate 15. On the other hand, a receiving member 30 which is a component transfer starting point of the linear feeder 29 is also arranged adjacent to the corner portion. Accordingly, since the end portion of the rectilinear feeder 29 viewed in the longitudinal direction has a positional relationship adjacent to the end portion of the storage container 9, a combination in which the rectilinear feeder 29 is closely aligned with the storage container 9 is established. Thus, downsizing of the apparatus is promoted.

By configuring the transfer means as an elongated unit such as the rectilinear feeder 29 and arranging it along the straight lateral side surface of the storage container 9, a space where integration of the storage container 9 and the rectilinear feeder 29 is minimized. This is effective for reducing the size of the apparatus.

Since the air cylinder 24 for raising and lowering the lift member 22 is attached to the outer wall surface of the storage container 9, the integration of the air cylinder 24 and the storage container 9 can be achieved with a minimum space, which is effective for making the apparatus compact. is there. The air cylinder 24 is an elevating means for the lift member 22, and can be replaced with an air cylinder 24 and can be an advancing / retracting output type electric motor.

The operational effects related to releasing the entanglement of parts are as follows.

Since the parts are iron bolts 1 that are piled up erratically, other thread ridges match the thread valleys, the corners of the head 3 bite into the thread valleys, 3 are brought into close contact with each other, or the weight of the bolt 1 is applied to form various entanglements and tensions, so that a large number of bolts 1 are intertwined and constrained. By sucking a part of the bolt 1 in a bundled state in this way to the low part 16 side by suction means such as a magnet 28, a collapse phenomenon occurs in a part of the component group.

Thus, a part of the group of parts that are in a bound state is broken and unwound, and the unwinding operation is continuously expanded in a chained manner, so that the range of the unrestrained state near the suction means 28 is widened. In this way, a part of the intertwined parts group is sucked to the low part 16 side, and the bolt 1 is made to stand by at the low part 16 by partial unraveling, and the movement of the bolt 1 is promoted.

In this way, the bolt 1 can be surely kept on standby at the low part 16, so that the bolt 1 can be supplied to the target location with the lift member 22 as the lifting means with high reliability.

Furthermore, since the bolt 1 that is waiting in the low part 16 is moved, it is possible to avoid raising the parts group that are piled up in a staggered manner. Therefore, the rising resistance of the lift member 22 is reduced, and the lift driving force of the lift member 22 can be reduced. For example, if the lift member 22 is moved up and down by the air cylinder 24, it is effective for reducing the size of the air cylinder 24.

If the pushing member 56 is a pushing means instead of the suction means 28 as described above, the pushing force acts on a part of the bundled parts group, and the bolt 1 in this portion collapses.

<Part of the group of parts in a bundled state is broken and unraveled in this way, and the unwinding operation is continuously expanded in a chained manner, and the range of the unconstrained state in the region near the pushing member 56 is widened. In this way, it is possible to move a part of the entangled or strung parts group to the low part 16 side and to make the bolt 1 stand by at the low part 16 by partial unraveling. Promotion is made.

Since the permanent magnet 28 as the suction means is arranged in a state of being embedded in the lift member 22, the attachment position in the vertical direction of the permanent magnet 28 is selected, and the permanent magnet 28 is permanently linked to the lifting operation of the lift member 22. The magnet 28 can be made to stand by at an optimal position. That is, when the lift member 22 is raised to the uppermost position, the permanent magnet 28 is placed at a position close to the low portion 16, so that the bolt 1 is released from the bundling group of the bolts 1 and the low portion 16. When the lift member 22 is lowered to the lowest position, the bolt 1 can be surely kept on standby on the placement surface 23.

The operational effects related to the sorting member are as follows.

As described above, the sorting member 32 is formed with the first sliding surface 32A and the second sliding surface 32B on which the lower surface of the head 3 and the lower end portion of the shaft portion 2 slide simultaneously, and the sorting member 32 is abnormal. The rail member 45 is continued in a state of being inclined to the opposite side to the falling direction of the bolt of the length. For this reason, the bolt 1 having a normal length slides simultaneously with respect to the first sliding surface 32A and the second sliding surface 32B, that is, the lower surface of the head 3 and the lower end portion of the shaft portion 2 are simultaneously supported by both sliding surfaces. . The sorting member 32 is provided with the inclination in the above-described direction. Accordingly, the normal bolt 1A is maintained in a stable posture by the support at the two locations on both sliding surfaces and the above-described inclination, and is reliably transferred. That is, in order to drop the

bolts

1B and 1C having an abnormal length from the sorting member 32, the falling side is opened, but the normal bolt 1A is transported without any risk of falling.

When the excessively long bolt 1B is transferred from the rail member 45 to the sorting member 32, the lower end portion of the shaft portion 2 comes into contact with the second sliding surface 32B, but the head portion 2 is separated upward from the first sliding surface 32A. Placed in position. For this reason, when the standing stability of the excessively long bolt 1B is lowered and vibrations for conveyance are added thereto, it is impossible to maintain the standing state, and the sorting member 32 falls to the opposite side of the inclination direction. It falls like this.

When the lower end portion of the shaft portion 2 is received by the second sliding surface 32B and the head 3 is lifted from the first sliding surface 32A like the overlong bolt 1B, the conveying force acts on the overlong bolt 1B. Thus, the head 3 is inclined rearward in the conveying direction, the corner of the head 3 is received by the first sliding surface 32A, and the corner of the lower end of the shaft portion 2 is in contact with the second sliding surface 32B. The corner of the head 3 may move so as to drag the first sliding surface 32A. That is, the excessively long bolt 1 B is inclined to the rear side in the conveying direction, and the lower end portion of the shaft portion 2 is in an inclined state preceding the head portion 3. Such an inclined state is not a state in which the first sliding surface 32A and the second sliding surface 32B are slidable on the lower surface of the head of the bolt and the lower end of the shaft, respectively. Therefore, the support stability of the excessively long bolt 1B cannot be maintained and falls from the sorting member 32.

As described above, when the excessively long bolt 1B is tilted in the transport direction, the head 3 hits the open-side corner 11 of the first sliding surface 32A, so that the head 3 is open on the sorting member 32, that is, in the open space 48. It will be in the state where it extrudes to the direction, and, thereby, the excessively long volt | bolt 1B falls.

When the overshort bolt 1C is transferred from the rail member 45 to the sorting member 32, the lower end portion of the shaft portion 2 comes into contact with the second sliding surface 32B, but the head portion 3 is located at a position lower than the first sliding surface 32A. If the lateral stability 32C of the sorting member 32 comes into contact and the standing stability of the overshort bolt 1C is lowered, and if vibrations for conveyance are added thereto, it becomes impossible to maintain the standing state. It falls as if it falls to the opposite side of the tilt direction.

Further, when the head 3 comes into contact with the open side corner 11 of the first sliding surface 32 A during the transitional period when the overshort bolt 1 C is transferred to the sorting member 32, the overshort bolt 1 C is elasticated at the open side corner 11. It falls as it is.

When the normal bolt 1A reaches the sorting member 32 in a state where the normal bolt 1A is turned sideways or the head 3 is on the lower side, it falls down mainly in a state where it hits the open side corner 11 and is bounced.

9 to 11 show a second embodiment of the present invention.

Example 2 is of a type in which a partition control member is provided in a storage container and the storage container is divided into a first storage space and a second storage space.

The bottom member 10 is formed by a first inclined surface 17 that is lowered toward the right side in FIG. 9 and a second inclined surface 18 that is lowered toward the upper side, and a single broken line 19 is formed on the boundary between both inclined surfaces. Appears in the direction.

A partition control member 60 for dividing the storage container 9 into a first storage space 9A and a second storage space 9B is provided. The partition control member 60 is formed of a flat plate-like member made of a material such as a steel plate or a stainless steel plate. Or you may comprise by flat members, such as a metal-mesh and punch metal. Here, it is a stainless steel plate, and both ends thereof are fixed to the inner surfaces of the

wall plates

12 and 14 by bolting or welding.

The first storage space 9A is a space for storing a large amount of bolts 1 replenished from the outside, and the second storage space 9B is a bolt 1 that is lifted by the lift member 22 from a large number of parts of the first storage space 9A. The waiting space is also reduced. As apparent from FIG. 9, in order to store as much bolt 1 as possible, the area of the first storage space 9A viewed in plan is wider than the area of the second storage space 9B.

Between the lower end part of the partition control member 60 and the bottom member 10, the bolts 1 heading from the first storage space 9A toward the second storage space 9B are entangled with each other, and the passing part 61 restricts the amount of bolt movement to the second storage space 9B. Is formed. There are various ways of forming the passage portion 61. As shown in FIG. 10A, an elongated board having a constant vertical width is attached to a predetermined height to form an opening space between the lower edge 60A of the board and the bottom member 10, and Is a passing portion 61.

Since the surface of the bolt 1 is jagged due to the formation of the male screw, the washer 3B is wobbled, or the head 3 is angular, when a large number of bolts 1 pass through the passage portion 61, the bolts 1 It becomes difficult for each part to be entangled or to be stretched and to pass through the passing part 61 smoothly. By giving such difficulty of passage, the amount of bolt movement from the first storage space 9A to the second storage space 9B is limited.

As shown by the arrow 62 in FIG. 11, the large number of bolts 1 replenished to the first storage space 9 A by the operator fills the space 9 A, but the second storage space 9 B side is in the passage portion 61. Due to the passage restriction, the number of bolts waiting there is significantly smaller than the storage amount of the first storage space 9A. When the bolt 1 in the second storage space 9B thus reduced is transferred by the lift member 22 to the rectilinear feeder 29 as the transfer means and the standby number is reduced, the entanglement and the tension between the bolts 1 in the passage portion 61 are reduced. In order to loosen the fit, it is replenished to the second storage space 9B side.

The lower edge portion 60A shown in FIG. 10A is linear in the horizontal direction. As described above, since a large number of bolts 1 are restricted by the passage portion 61, the piled height of the bolts 1 in the second storage space 9B, that is, the standby number is set by the height position of the lower edge portion 60A. .

The opening shape of the passage portion 61 is various shapes depending on the shape and size of the part. As shown in FIG. 10A, when the lower edge portion 60A extends linearly in the horizontal direction and the passage area of the passage portion 61 is sufficiently large, the first inclined surface 17 and the second inclined surface 17 Since the bolt 1 is concentrated too much on the low part 16 due to the combination of the surfaces 18, as shown in FIG. 10A, the end of the partition control member 60 is extended downward to provide a regulating piece 60B. With this restricting piece 60B, the number of bolts 1 passing through the low portion 16 side of the passage portion 61 is reduced, the standby bolt amount of the low portion 16 is reduced, and the lift load of the lift member 22 is reduced.

The partition control member 60 shown in FIG. 10B is obtained by extending a regulating projection piece 60C downward from the central portion of the lower edge portion 60A in the horizontal direction, whereby a bolt from the first storage space 9A to the second storage space 9B. The amount of movement is optimized.

The partition control member 60 shown in FIG. 10C is configured such that the lower edge of the partition control member 60 is an inclined lower edge portion 60D that matches the inclination of the first inclined surface 17, and the amount of bolt passing through the inclined lower edge portion 60D. Is increasing.

Further, as shown in FIG. 9, the partition control member 60 is arranged in parallel with the wall plate 13 and the wall plate 15, but this is arranged in an oblique direction, curved or bent, The passing amount of the passing part 61 and the bolt storing amount of the second storing space 9B can be adjusted.

As described above, it is possible to appropriately select the opening shape of the passage portion 61 and select the number of bolts to be waited at which location in the second storage space 9B.

In order for the bolt 1 to fall from the sorting member 32 to the second storage space 9B, the fall height H for that purpose must be formed in the second storage space 9B. In the second storage space 9B, since the standby number of the bolts 1 is much smaller than that of the first storage space 9A, the fall height H can be secured as shown in FIG. If the amount of bolt in the second storage space 9B is full as in the first storage space 9A, a sufficient fall height H cannot be ensured, so the fall is not made vigorously or the fallen bolt 1 bounces. Although it spills outside the storage container 9, such an abnormal phenomenon does not occur here.

Other configurations are the same as those of the first embodiment including the portions not shown in the drawing, and members having similar functions are denoted by the same reference numerals.

The operational effects of the second embodiment described above are as follows.

Since the bolt 1 is a component having a square shape or a jagged shape such as a male screw, when the bolt 1 passes through the passage portion 61, the bolts 1 are intertwined with each other or stuck together, making smooth passage difficult. Since the passage part 61 is subjected to such a passage restriction, the bolt amount stagnating in the second storage space 9B is significantly smaller than the bolt amount stored in the first storage space 9A. The second storage space 9 B functions as a standby space for the bolt 1 that has been reduced in this way. For this reason, the number of bolts raised by the lift member 22 is not excessive, and is necessary for raising the lift member 22. Power can be reduced. It is economical because the air cylinder 24 for lifting the lift member 22 can be downsized and the amount of compressed air to be used can be reduced. Further, when the lift member 22 is moved up and down by an electric motor of advancing / retreating output type instead of the air cylinder 24, it is effective for saving power consumption.

In other words, for example, when the bolt 1 is stored in a large amount like the first storage space 9A, it is necessary to push up the lift member 22 by overcoming the resistance due to the weight of the large amount of bolts and the entanglement or tension between the bolts. However, since the bolt 1 reduced in quantity is waiting in the second storage space 9B, the rising resistance of the lift member 22 is reduced.

On the other hand, in the first storage space 9A, the function of storing a large amount of bolts 1 is reliably achieved by the passage restriction in the passage portion 61. Even if the storage space of the first storage space 9A is enlarged, the second storage space An adverse effect such as excessive supply to 9B can be avoided, and the bolt supply interval to the first storage space 9A can be extended, which is advantageous in terms of bolt supply management.

As described above, it is possible to increase the bolt storage amount in the first storage space 9A and to appropriately reduce the bolt standby amount in the second storage space 9B.

Other functions and effects are the same as those of the first embodiment.

12 to 14 show Embodiment 3 of the present invention.

In Example 3, the passage portion 61 of the partition control member provided in the storage container is formed at a location where the bolt 1 is guided toward the lift member 22.

As shown in FIG. 12, the partition control member 60 has a long plate 60E and a short plate 60F formed in a horizontally long inverted L shape, and a passage portion between the lower end of the short plate 60F and the bottom member 10 (18). 61 is formed. Then, as shown in FIG. 13, the passage portion 61 is also formed at the end portion of the long plate 60E by cutting the end portion of the long plate 60E in an oblique direction.

The passage portion 61 formed as described above is formed at a location approaching the lift member 22. That is, as shown in FIG. 12, the lift member 22 is disposed on the upper right side of the storage container 9, and the passage portion 61 is formed on the right side of the partition control member 60. With such an arrangement, the passage portion 61 is formed at a location close to the lift member 22.

Inclined guide plates

60G and 60H are formed on the upper edges of the long plate 60E and the short plate 60F, and when the large number of bolts 1 are replenished to the first storage space 9A as indicated by the arrow 62, the first storage space 9A is smoothly supplied. And is not spilled toward the second storage space 9B.

The bolt 1 stored in the first storage space 9 A passes through the passage portion 61 and slides down the second inclined surface 18 and is guided toward the lift member 22 as indicated by an arrow 63. Although the passage 61 is formed as described above, the shape of the passage opening in this portion, such as stopping the cut portion in the oblique direction formed at the end of the long plate 60E, can be changed to the shape and size of the part or lift. Various changes can be made according to the number of times the member 22 is raised and lowered.

Other configurations are the same as those of the previous embodiments, including portions not shown, and the same reference numerals are used for members having similar functions.

The operational effects of the third embodiment described above are as follows.

Since the passing portion 61 is formed at a location close to the lift member 22, the bolt 1 subjected to the movement amount limitation in the passing portion 61 is guided toward the lift member 22 by the second inclined surface 18. That is, since the number of passages is limited by the passage portion 61 and moves toward the lift member 22, the number of bolts lifted by the lift member 22 does not become excessive, and the lifting load of the lift member 22 is reduced.

The bolt 1 that has passed through the passage portion 61 is guided toward the lift member 22, and on the other hand, the bolt 1 falls from the sorting member 32 to a location separated from the lift member 22. As a result, it is possible to prevent the lift member 22 from being excessively biased and distributed, and the lifting load of the lift member 22 is reduced.

Other functions and effects are the same as in the previous embodiments.

15 to 17 show a fourth embodiment of the present invention.

In Example 4, a long and narrow guide inclined surface toward the low part 16 is formed on a part of the inclined surface 17 of the bottom member 10 of the second storage space 9B.

The guiding inclined surface 65 is formed by a long and narrow inclined surface toward the low portion 16 on a part of the inclined surface 17 (the first inclined surface 17) of the bottom member 10. The guide inclined surface 65 is configured in a horizontal state as viewed in the width direction or in an inclined state so that the end portion on the partition control member 60 side becomes higher and becomes lower toward the low portion 16 side. It is configured as follows.

As shown in FIGS. 15, 17 A, and 17 B, the guide inclined surface 65 is formed of an elongated flat plate surface having a width W and is lowered toward the low portion 16 side. Since the inclined surface 17 is formed in a state of being continuous with the guide inclined surface 65, a broken line (ridge line) indicated by reference numeral 66 appears. The cross section (17A)-(17A) in FIG. 15 is FIG. 17A, and the cross section (17B)-(17B) in FIG. 15 is FIG. 17B.

Furthermore, the guide inclined surface 65 is in the horizontal direction when viewed in the width direction, that is, the width W direction. As shown in FIGS. 17A and 17B, the surface of the guide inclined surface 65 matches the horizontal line 67 when viewed in the cross section of the guide inclined surface 65. That is, the guide inclined surface 65 is not inclined in the horizontal direction, and the component transfer direction is inclined low. Alternatively, the guide inclined surface 65 is inclined so that the end on the partition control member 60 side becomes higher when viewed in the width direction, that is, the width W direction. That is, as shown in FIG. 17C, the guide inclined surface 65 has a higher end on the partition control member 60 side, and therefore, an inclination angle θ is formed.

The guiding inclined surface 65 is disposed along the inner wall of the wall plate 15, and the lower end portion thereof is continuous with the low portion 16. Alternatively, the guide inclined surface 65 may be arranged in the oblique direction of FIG. 15 without being along the inner wall of the wall plate 15, and the lower end portion thereof may be continued to the low portion 16.

The operational effects of the fourth embodiment described above are as follows.

The bolt 1 stored in the second storage space 9B is guided to the low part 16 so as to slide down the guide inclined surface 65. This is because a part of the bolt 1 stored in the entire area of the second storage space 9B is guided to the low part 16 via the elongated guide inclined surface 65 without stagnation, and thus the bolt 1 in the second storage space 9B. Successively shifts to the low part 16 via the guide inclined surface 65. In other words, among the bolts 1 in the entire area of the second storage space 9B, the bolt 1 on the guide inclined surface 65 slides down the elongated inclined surface toward the low portion 16, so that the bolt 1 in the second storage space 9B is guided and inclined. It is reliably transferred onto the low part 16, that is, the lift member 22 through the surface 65, and the parts are reliably supplied to the target location by the lift and the operation of the transfer means (straight forward feeder) 29.

Since the guide inclined surface 65 is horizontal when viewed in the width W direction, the bolt 1 existing on the guide inclined surface 65 is less likely to fall from the guide inclined surface 65, and the low portion 16. As a result, the number of parts going to the head can be increased, and the number of bolts lifted by the lift member 22 can be increased accordingly.

Alternatively, since the guide inclined surface 65 is configured in an inclined state so that the end portion on the partition control member 60 side becomes higher, the guide inclined surface 65 is disposed along the inner surface of the wall plate 15 of the storage container 9. In such a case, the bolt 1 placed on the guide inclined surface 65 slides down while rubbing the inner surface of the wall plate 15 of the storage container 9, whereby the bolt 1 on the guide inclined surface 65 is guided and inclined. This is suitable for increasing the number of bolts that are less likely to fall from the surface 65 and go to the lower portion 16.

If the transfer posture of the bolt 1 is abnormal or the size of the bolt 1 is too large or too small, the bolt 1 falls from the sorting member 32 arranged in the linear feeder 29 into the second storage space 9B. May be configured. When such a falling configuration is adopted, the falling bolt 1 is preferentially transferred by the lift member 22 by receiving the falling bolt 1 by the guide inclined surface 65, and the second storage space 9B As a result, the bolts can be supplied smoothly without excessively storing the bolts.

Since the bolts 1 transferred onto the lift member 22 are in various postures, all of the bolts 1 transferred to the linear feeder 29 are not conveyed in a normal posture. For this reason, the bolt 1 in an abnormal posture falls from the sorting member 32 to the second storage space 9B with a certain probability. The bolt 1 that has fallen in this way is guided preferentially to the low part 16 via the guide inclined surface 65, whereby the bolt storage amount in the second storage space 9B can be optimized.

Other functions and effects are the same as in the previous embodiments.

As described above, the present invention is a component supply device that can efficiently transport a plurality of components and simplify the device structure. Therefore, it can be used in a wide range of industrial fields, such as a car body screwing process for automobiles and a sheet metal assembling process for home appliances.
