JP 2003-276846 A Japanese Patent No. 4276984 Japanese Patent Publication No. 07-005183

  The technique described in Patent Document 1 has a problem that it is difficult to increase the amount of parts stored in the hopper because the hopper is arranged at the lower part of the elongated chain with a magnet and the sliding plate. There is. In addition, there is a problem that it is impossible to reliably transfer a part that has been raised in a sliding state to the next conveying means.

  According to the technique described in Patent Document 2, there is a problem that it is difficult to accurately transfer the adsorbed nut to a specific portion of the transfer means.

  According to the technique described in the cited document 3, there is a problem in that it is difficult to accurately transfer a part to the transfer means by causing the part to reach a specific location of the transfer means.

  The present invention has been provided to solve the above-described problems, and an object of the present invention is to provide a component supply device and a supply method capable of transporting components reliably and efficiently and simplifying the device structure.

The invention according to claim 1 is a component supply device,
A storage container for parts composed of at least a wall plate and a bottom member;
A transfer substrate formed by one of the wallboards;
It is composed of a metal chain, a metal belt, a synthetic resin belt, and the like, and an endless rotating member that sets a movement path of components along the transport board according to the arrangement form;
A suction member attached to the circumferential member and moving along the outer surface of the transport substrate;
A magnet that is attached to the suction member and moves on a predetermined movement path while adsorbing the components in the storage container to the inner surface of the transport substrate and sliding the inner surface;
A transfer means which is provided outside the storage container and transfers parts from the storage container to a target location;
It is characterized by including a receiving member disposed on or in the vicinity of the moving path so as to receive the component that has been moved along the moving path and is disposed on the transfer means.

  It consists of a metal chain, metal belt, synthetic resin belt, etc., and an endless circular member that sets the movement path of the component along the transport board is provided depending on the arrangement form, and a magnet is attached to this circular member. The provided suction member is attached. Therefore, the moving path of the component attracted by the magnet can be freely selected by arranging the circulating member in an oval shape, a triangular shape having round corners, or the like. For this reason, it is realized that the component accurately reaches a predetermined location of the transfer means, and the operation reliability as the component supply device is improved.

  In addition, the transfer substrate that forms a part of the storage container is erected substantially vertically, and the bottom member is inclined with respect to the horizontal direction so that the transfer substrate side is lowered. As a result, it is possible to adsorb all the parts collected at the bottom of the storage container and collected at the bottom of the storage container and reach the receiving member of the transfer means. For this reason, all the parts in the storage container are used up, and the remaining of old parts can be avoided.

  The component that slides inside the transfer substrate reaches the receiving member of the transfer means along the movement path. At this time, since the component is received by the receiving member, the component remains on the receiving member, and thereafter, the suction member passes in a state where the component is not attracted. Accordingly, the components that have slid on the inner surface of the transfer substrate are accurately transferred onto the receiving member without being dispersed, and accurate component transfer is realized. Further, since there are a plurality of attracting parts by magnets, the parts move in a group having a width orthogonal to the traveling direction. For this reason, even if the receiving member is displaced in the vicinity of the movement path, the parts can be transferred to the receiving member as described above.

  A part of the storage container is formed by selecting the arrangement form of the orbiting member and making the movement path set by the movement trajectory of the suction member the so-called large turning form in which the depth direction and width direction of the storage container are increased. The surface area inside the transfer substrate can be increased, and accordingly, the storage volume of the storage container can be increased. That is, it is possible to increase the amount of parts accommodated.

  Since the suction member circulates within the range of the outer area of the transport substrate formed by one of the wall plates, the movable member can be compactly gathered along the transport substrate.

The invention according to claim 2 is a supply method,
A storage container for parts composed of at least a wall plate and a bottom member;
A transfer substrate formed by one of the wallboards;
It is composed of a metal chain, a metal belt, a synthetic resin belt, and the like, and an endless rotating member that sets a movement path of components along the transport board according to the arrangement form;
A suction member attached to the circumferential member and moving along the outer surface of the transport substrate;
A magnet that is built in the suction member and moves on a predetermined movement path while adsorbing the components in the storage container to the inner surface of the transport substrate and sliding the inner surface;
A transfer means which is provided outside the storage container and transfers parts from the storage container to a target location;
Preparing a component supply device configured to include a receiving member disposed on or in the vicinity of the moving path so as to receive the component that has been moved along the moving path, disposed on the transfer means;
The suction member is moved along the outer surface of the transport substrate by the revolving operation of the transport member, and the component adsorbed on the inner surface of the transport substrate is moved along the movement path along with the movement of the suction member. It is characterized in that the received part reaches the receiving member.

  The effect of the invention of the supply method is the same as that of the component supply apparatus.

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

  1 to 6 show a first embodiment of the present invention.

  First, the target part will be described.

  FIG. 9 shows the target part. FIG. 3A 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> 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.

  Moreover, what is shown to FIG. 9 (B) is comprised by the flange 6 by which the head 3 was shape | molded integrally with the hexagon part 3A and the hexagon part 3A. In addition, the external thread is processed into the axial part 2, the external thread is shown only in FIG. 9 (A) and (B), and illustration of the external thread is abbreviate | omitted in the other figure.

  FIG. 9C 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 that is attracted by a magnet.

  There are various target parts as described above, but here is the flange-integrated bolt 1 shown in FIG. 9B. The dimensions of the bolt 1 are 3 mm and 13 mm for the diameter and length of the shaft 2, 9 mm and 1 mm for the washer diameter and thickness, respectively, and 6 mm and 2.5 mm for the hexagonal corner dimensions and height, respectively. is there.

  As the target parts, those having the head portion and the shaft portion as described above are illustrated, but projection nuts, washers, shafts, and the like with welding projections can also be supplied as the subject of the present invention.

  Next, the storage container will be described.

  As shown in FIG. 1, the storage container 9 in which a large number of bolts 1 are stored has a rectangular box shape when viewed from directly above. A bottom member 10 is formed by forming a square plate made of stainless steel into an arc shape. Stainless steel wall plates 12, 13, 14, and 15 are joined to the four sides of the bottom member 10 by welding or bolting.

  The storage container 9 is provided with a transport substrate on which suction means for moving the bolt 1 in a sliding state or applying a magnet suction force to the bolt 1 is arranged. This transfer board is formed by one of wall plates 12, 13, 14, and 15. Here, the wall board 12 is used as a transfer board, and the transfer board is also denoted by the same reference numeral 12. The transport substrate 12 is composed of a flat plate material standing upright in the vertical direction, and is composed of a non-magnetic material such as stainless steel or synthetic resin in order to apply a magnet attraction force described later more strongly to the parts. Here it is made of stainless steel.

  As shown in FIG. 4, the bottom member 10 is inclined so that the side of the transport substrate 12 is lowered, and the vicinity where the bottom member 10 and the transport substrate 12 intersect is a low portion 16.

  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.

  The storage container 9 is disposed on the support plate 11 and is fixed to a stationary member 50 such as a machine frame.

  Next, the rotating member will be described.

  The circling member 17 is composed of a metal chain, a metal belt, a synthetic resin belt, or the like, and is an endless or annular member. Any of a metal chain, a metal belt, a synthetic resin belt, and the like may be used, but here, a metal chain hung on a sprocket wheel. This metal chain is also denoted by reference numeral 17.

  The sprocket wheel 18 is disposed near the outer surface of the transfer substrate 12. Various driving means such as an electric motor and a hydraulic motor can be adopted as the driving means for rotating the sprocket wheel 18, but the electric motor 19 is used here. A reduction box 20 having a reduction gear built in the electric motor 19 is integrated, and an output shaft 21 protruding from the reduction box 20 is coupled to the center of the sprocket wheel 18. The rotation axis of the output shaft 21 is perpendicular to the outer surface 12 </ b> A of the transport substrate 12. That is, the rotation axis of the output shaft 21 is arranged in the horizontal direction, and the disc-shaped sprocket wheel 18 and the transport substrate 12 are in a parallel positional relationship. The electric motor 19 and the deceleration box 20 are attached to the transport substrate 12 via an arm member 23 coupled to the transport substrate 12 by welding or the like.

  Next, the arrangement of the sprocket wheels will be described.

  As is clear from FIG. 2, the sprocket wheel 18 driven by the electric motor 19 is arranged slightly close to the lower side of the central portion of the transport substrate 12, and the sprocket wheel 24 is arranged immediately above. An endless metal chain 17 is stretched between the sprocket wheel 18 and the sprocket wheel 24. The rotating shaft 25 of the sprocket wheel 24 is supported by an arm member 26 having the same structure as the arm member 23 described above. In FIG. 2, the arm members 23 and 26 are shown by two-dot chain lines in order to make the surrounding structure easy to see.

  Both sprocket wheels 18 and 24 have the same diameter, so that the metal chain 17 is arranged in an oval shape. The positional relationship between the sprocket wheel 24 and the transport substrate 12 is the same as the positional relationship of the sprocket wheel 18 with respect to the transport substrate 12 as described above. Therefore, the rotating member 17 is in a positional relationship parallel to the transport substrate 12.

  In FIGS. 1 and 2, sprocket wheels and metal chains are simply illustrated, but are accurately illustrated in FIG. 5.

  Next, the suction member will be described.

  As shown in FIG. 5, a plurality of suction members 27 are coupled to the metal chain 17. Here, as shown in FIG. The suction member 27 circulates along the outer surface 12 </ b> A of the transport substrate 12. A magnet (permanent magnet) 29 is accommodated in a box-shaped container 28, and a magnet 29 is sealed by welding a lid plate 30. The container 28 and the cover plate 30 are also made of a nonmagnetic material such as stainless steel.

  The suction member 27 moves along the outer surface 12A of the transport substrate 12. As will be described later, when moving while sucking the bolt 1, the lid plate 30 rubs the outer surface 12 </ b> A of the transport substrate 12, but passes through a concave cross-sectional portion 53 described later and does not suck the bolt 1. Then, since a suction force toward the outer surface 12A is not acting, a slight gap is formed between the cover plate 30 and the outer surface 12A. Such rubbing movement and gap formation are set by the distance between the metal chain 17 and the outer surface 12A and the slackness of the metal chain 17.

  Various structures can be employed for coupling the suction member 27 to the metal chain 17. Here, one end of an elongated strip-shaped arm plate 32 is coupled to the metal chain 17 and the other end is coupled to the container 28 by bolts or welding. The coupling to the metal chain 17 is performed by caulking the coupling pin 33 of the chain to the arm plate 32, and reference numeral 34 indicates the caulking portion.

  Next, the movement route will be described.

  The suction member 27 circulates at a place separated from the metal chain 17 by an arm length of the arm plate 32 along an oval locus. This oval movement locus is a movement path. The movement path is indicated by a two-dot chain line in FIGS. 2, 5, etc., and is denoted by reference numeral 35, and is similar to the oval shape of the metal chain 17. As shown in FIG. 5B, a plurality of bolts 1 stored in the storage container 9 are attracted by a magnet 29 and moved in a sliding state while rubbing the inner side surface 12B of the transfer substrate 12. This movement locus is the movement path 35.

  The arc shape of the bottom member 10 described above is set along the elliptical arc shape.

  The receiving member of the transfer means described later is arranged on or near the movement path 35.

  Next, the transfer means will be described.

  The transfer means is provided outside the storage container 9 and transfers the bolt 1 coming out of the storage container 9 to a target location. The transfer means slides down the bolt 1 using a downward slope, or uses vibration. Various types, such as a transporting one, can be employed. Here, the latter is a vibration type linear feeder.

  A straight feeder as a transfer means is indicated by reference numeral 38. The rectilinear feeder 38 is arranged along the outer surface of the flat wall plate 15 in the longitudinal direction, that is, the transfer direction. In the rectilinear feeder 38, a receiving member 39 to which the bolt 1 is transferred, a suspending member 40 continuing to the receiving member 39, and a selecting member 41 continuing to the suspending member 40 are linearly arranged. Then, the bolt 1 is supplied from the sorting member 41 to the target location, or is supplied to the target location via the suspension member 42 similar to the suspension member 40.

  On the elongated base member 43, a receiving member 39, a hanging member 40, a sorting member 41, and a hanging member 42 are coupled via bolts or the like via support members 44, 45, 46 and 47. The base member 43 is arranged above the stationary member 50 by two obliquely arranged leaf springs 49, and the electromagnet 51 applies vertical vibrations to the base member 43, so that the feed to the left in FIG. An output component is formed and bolt transfer is performed.

  In order to concentrate the bolt 1 in the center of the receiving member 39, an arcuate surface 52 (see FIGS. 2 and 3) having a lowered center is formed to form a shallow concave cross-sectional portion 53. This concave cross section extends in the transfer direction of the transfer means 38. And the above-mentioned movement path | route 35 has passed the location where the volt | bolt 1 is transferred, ie, the concave-shaped cross-section part 53. Since a plurality of bolts 1 move in a group while rubbing the inner surface 12B of the transport substrate 12, even if the receiving member 39 is disposed at a position slightly deviated from the movement path 35, that is, in the vicinity of the movement path 35. The bolt 1 is supplemented on the receiving member 39.

  Note that the arcuate concave cross section 53 can be a V-shaped concave cross section composed of two flat slopes.

  As shown in FIG. 6B, the suspension members 40 and 42 are supported on the sliding surfaces 56 of the pair of parallel rail members 55 in a state where the lower surface of the flange 6, that is, the lower surface of the head 3 can slide. . And the axial part 2 passes through the passage space 54 between both the rail members 55 in a suspended state. The lower portions of both rail members 55 are integrated by a connecting member 57.

  Next, the guide member will be described.

  When the bolt 1 that has been attracted to and moved by the inner surface 12B of the transport substrate 12 is transferred onto the receiving member 39, one or two small bolts 1 cannot be placed on the receiving member 39, and the storage container 9 May fall into the inside. Such a fall lowers the transfer efficiency, so a guide plate 58 is arranged to prevent it. The guide plate 58 has a bowl-like shape protruding from the transport substrate 12 in a positional relationship that is continuous with the concave cross-sectional portion 53, and is disposed on the upper side of the storage container 9, and the inclined portion 59 that is lowered toward the concave cross-sectional portion 53 side. Is provided. Here, as shown in FIGS. 2 and 3, the guide plate 58 has an arc shape along the movement path 35, and the right side from the top is an inclined portion 59 that is inclined downward. The guide plate 58 is welded to the inner side surface 12B of the transport substrate 12.

  As shown in FIG. 3, the upper end of the wall plate 15 is a portion that is close to the side surface of the receiving member 39 and extends to the vicinity of the end portion of the guide plate 58.

  If the receiving member 39 is disposed at a position slightly deviated from the movement path 35, that is, in the vicinity of the movement path 35, there is a risk of bolt falling. In such a case, it is desirable to effectively utilize the guide plate 58.

  A protective plate 61 erected in the vertical direction is joined to the side surface of the receiving member 39 opposite to the guide plate 58 by welding or bolting. The protection plate 61 extends to the immediate vicinity of the inner side surface 12B of the transport substrate 12, whereby the receiving member 39 is disposed in a space portion where the protection plate 61 and the transport substrate 12 intersect. Therefore, even when the bolt 1 moves at a high speed, the bolt 1 received by the concave cross section 53 is abnormal due to the fall prevention function by the guide plate 58 and the barrier function by the protective plate 61 and the transport substrate 12. There is no scattering in the direction.

  Next, the sorting member in the transfer means will be described.

  When the bolt 1 is transported in an abnormal posture such as laterally or obliquely, it is necessary to eliminate such a bolt 1. Alternatively, in the part supply process location, a normal bolt 1A having a normal length, an excessively long excessive bolt 1B, an excessively short excessive bolt 1C, or the like may be transferred in the vicinity, for some reason. For example, an operator may mistakenly mix the excessive bolt 1B or the excessive bolt 1C into the normal bolt 1A. In preparation for such an abnormal mixture, the above-described sorting member 41 is arranged in a state of being continuous with the suspension member 40.

  The sorting member 41 is a structural part for dropping the normal bolt 1A in the abnormal posture and the bolts 1B and 1C in the abnormal length into the storage container 9, so that the left side of the sorting member 41 is opened as shown in FIG. ing. This open space is shown in FIG. 6 as an open space 62. At the same time, a notch 15A is provided in the upper part of the wall plate 15 so that the bolts 1A, 1B, 1C having an abnormal posture or an abnormal length can fall into the storage container 9.

  As shown in FIG. 6C, a flat first sliding surface 41A on which the lower surface of the flange 6 slides and a flat second sliding surface 41B on which the lower end portion (lower end surface) of the shaft portion 2 slides are formed. The vertical distance between the sliding surfaces 41A and 41B is the same as the length of the shaft portion 2 (the shaft portion 2 of the normal bolt 1A). By doing so, the lower surface of the flange 6 and the lower end of the shaft portion 2 simultaneously slide on the first sliding surface 41A and the second sliding surface 41B by the conveyance vibration. In order to smoothly transition the bolt from the suspension member 40 to the selection member 41, the passage space 54 of the suspension member 40 is communicated with the space above the second sliding surface 41B.

  Then, the bolts 1B and 1C having an abnormal length are tumbled in the direction indicated by the arrow lines in FIGS. 6D and 6E. On the other hand, the sorting member 41 is arranged in a posture inclined to the opposite side to the falling direction. That is, the upper side of the sorting member 41 is inclined rightward with respect to the vertical line OO. In order to prevent the bolt from falling to the outside opposite to the arrow, the protective plate 63 is fixed to the outer surface of the sorting member 41 by welding or bolting.

  The normal bolt 1A is supported so that the lower surface of the flange 6 and the lower end of the shaft portion 2 can simultaneously slide on the first sliding surface 41A and the second sliding surface 41B, respectively, as shown in FIG. In a stable state as if leaning to the right side, it is transferred as it is and transferred to the suspension member 42.

  When the excessively long bolt 1B is transferred to the sorting member 41, the flange 6 is placed at a position floating from the first sliding surface 41A, so that the standing state of the bolt 1B becomes unstable, and vibration is added thereto. Fall down in the direction of the arrow. Moreover, although the upper side of the excessively long bolt 1B is slightly inclined to the right side of the vertical line OO, it falls down due to the above unstable state. 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 41 is slightly tilted so that the sorting member 41 can easily fall. As shown in FIG. 6D, the excessively long bolt 1B becomes unstable because the outer peripheral portion of the flange 6 is in contact with the upper portion of the sorting member 41 and is in a posture close to the vertical direction. It is.

  When the overshort bolt 1C is transferred to the sorting member 41, the flange 6 is placed at a position lower than the first sliding surface 41A, so that the standing state of the bolt 1C becomes unstable, and vibration is added thereto. Fall down in the direction of the arrow. 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. 6E, the excessively short bolt 1C becomes unstable because the outer peripheral portion of the flange 6 comes into contact with the upper portion 41C of the sorting member 41 and is further leftward than the vertical direction. This is because the posture is inclined.

  When the length of the normal bolt 1A is changed, the sorting member 41 is removed from the support member 46 and replaced with a sorting member 41 having a different distance between the first sliding surface 41A and the second sliding surface 41B. By doing so, it is possible to flexibly cope with normal bolts 1A having different lengths.

  In order to smoothly transfer the bolt 1 from the suspension member 40 to the selection member 41, the rail member 55 on the wall plate 15 side is longer than the other rail member 55 by a length L (see FIG. 1). Only set longer. As shown in FIG. 1, since the bolt 1 transferred in the suspended state has a difference in length L, the rail member 55 on the side far from the wall plate 15 is first moved to the position of L. 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 41 inclined outward. That is, as shown in FIG. 6C, the normal bolt 1A smoothly moves to the selection member 41.

  If the bolt 1 is moved sideways or obliquely on the suspension member 40 for some reason, or if the head 3 is moved downward, the bolt 1 is not properly suspended. It falls from the suspension member 40 toward the sorting member 41 and collides with a part of the sorting member 41. As a result, the bolt 1 is repelled and falls into the storage container 9.

  Thus, if the bolt posture on the suspension member 40 is abnormal or the length of the bolt is too long or too short, they all fall into the storage container 9, as shown in FIG. Only the bolt 1 </ b> A in the state shown will pass, and the abnormal bolt can be reliably removed. In other words, as shown in FIG. 6C, the lower surface of the flange 6 slides on the first sliding surface 41A, and the lower end portion of the shaft portion 2 slides on the second sliding surface 41B. The normal bolt 1A is allowed to pass only when it is made.

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

  After the sorting member 41, it is put in a receiving box or transferred to a hanging member 42 as shown. Here, a predetermined number of bolts are passed from the suspension member 42 by the counting unit 64, accumulated in the standby box 65, and a predetermined number of bolts 1 are taken out by opening the lid of the box 65.

  There are various configuration examples of the counting unit 64. Here, this is a type in which the pair of regulating members 66 and 67 are advanced and retracted. The restricting member 66 that advances and retreats with the air cylinder 68 advances to stop the first bolt 1, and the restricting member 67 that advances and retreats with the air cylinder 69 stands by at the retracted position. When the regulating member 67 advances to stop the movement of the second bolt 1 and then the regulating member 66 moves backward, only the first bolt 1 falls into the standby box 65.

  Thereafter, when the restricting member 67 moves backward at the same time as the restricting member 66 advances again, the second bolt 1 is stopped at the first position, and the second bolt falls in the above order. Made.

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

  As shown in FIGS. 3 and 4, the sprocket wheel 18 is rotated by the electric motor 19 while the storage container 9 is filled with a large number of bolts 1, and together with the sprocket wheel 24 via the metal chain 17. Also rotates. As a result, the suction member 27 moves on the movement path 35. When the suction member 27 moves upward from the bottom of the storage container 9, the bolt 1 near the bottom is sucked to the inner surface 12 </ b> B of the transport substrate 12, but the magnet 29 passes due to the load of the stacked bolt 1. Then, the adsorption to the inner side surface 12B is released, and the bolt 1 existing deep in the bottom does not rise.

  When the suction member 27 passes through the upper zone 70 (see FIG. 3) of the storage bolt, the plurality of bolts 1 slides along the movement path 35 in a state of being sucked by the inner side surface 12B in a group. The suction member 27 is received on the concave cross section 53 of the receiving member 39, and the suction member 27 moves toward the bottom of the storage container 9 again leaving the bolt 1 on the concave cross section 53. Such a cyclic operation is continuously performed by the seven suction members 27. In the upper zone 70, since the load of the bolt 1 is slight, it moves while rubbing the inner side surface 12 </ b> B while being pulled by the magnet 29.

  When the suction member 27 moves while sucking the bolt 1, the suction member 27 is also sucked by the outer surface 12A, so that the cover plate 30 moves along the movement path 35 while sliding on the outer surface 12A.

  The bolt 1 that has reached the receiving member 39 has a posture such as a lateral direction or an oblique direction. At this time, while the posture of the bolt 1 is corrected in the longitudinal direction of the concave cross section 53 by the conveyance vibration of the rectilinear feeder 38, the bolt 1 moves to the suspension member 40 and enters the suspended state shown in FIG. The bolt 1 moves to the selection member 41 in this hanging posture, where the lower surface of the flange 6 slides on the first sliding surface 41A and the end surface of the shaft portion 2 slides on the second sliding surface 41B. Thereafter, the bolt 1 is transferred from the counting unit 64 to the standby box 65 via the suspension member 42.

  In addition, since the piled weight of a bolt will be reduced if the storage amount of the bolt 1 reduces, the bolt 1 attracted | sucked to the magnet 29 will move the movement path | route 35 so that the bolt 1 which has not received the attraction force may be divided. Move along.

  When the remaining bolts 1 in the storage container 9 are reduced by the operation as described above, the bolts 1 are concentrated on the lower portion 16 shown in FIG. The supply operation is performed until the suction bolt 27 is completely attracted to the concentrated bolt 1 and the bolt 1 is exhausted.

  In this embodiment, the bolt 1 having the head portion and the shaft portion is supplied as described above. However, as described above, even when supplying a projection nut, a washer, a shaft or the like with a welding protrusion, the bolt 1 is supplied. The same supply movement is possible. When supplying projection nuts, washers, shafts, etc., the structure of the receiving member 39, the suspension member 40, the selection member 41, etc. is changed to one that matches each part.

  Note that, instead of the air cylinder, an electric motor that outputs and retreats may be employed. It is also possible to replace the permanent magnet with an electromagnet. In the case of using an electromagnet, for example, an elongated power supply member is attached to the outer surface 12A of the transport substrate 12 along the movement path 35 in an insulating state, and is rubbed with a current collecting shoe attached to the suction member 27 while being attached to the electromagnet. Energize.

  Operations of the above-described electric motor, linear feeder, counting unit, and the like 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.

  In addition to a metal chain, a metal belt, a synthetic resin belt, and the like, an endless circular member 17 that sets a movement path 35 of the bolt 1 along the conveyance substrate 12 is provided depending on the arrangement form. A suction member 27 having a magnet 29 is attached to the member 17. Therefore, the moving path 35 of the bolt 1 attracted to the magnet 29 can be freely selected by arranging the rotating member 17 in an oval shape, a triangular shape having round corners, or the like. For this reason, it is possible to accurately reach the bolt 1 to a predetermined portion of the linear feeder 38 which is a transfer means, and the operation reliability as the component supply device is improved.

  In addition, the transfer substrate 12 that forms a part of the storage container 9 is erected substantially in the vertical direction, and the bottom member 10 is inclined with respect to the horizontal direction so that the transfer substrate 12 side is lowered. As a result, it is possible to adsorb all the bolts 1 collected at the bottom portion of the bottom member 10 and accumulated at the bottom of the storage container 9 and reach the receiving member 39 of the transfer means 38. For this reason, all the bolts 1 in the storage container 9 are used up, and the remaining of the old bolts 1 can be avoided.

  The bolt 1 sliding inside the transport substrate 12 reaches the receiving member 39 of the transfer means 38 along the movement path 35. At this time, since the bolt 1 is received by the receiving member 39, the bolt 1 remains on the receiving member 39, and thereafter, the suction member 27 passes in a bolt non-adsorbed state. Therefore, the bolt 1 that has slid on the inner surface of the transport substrate 12 is accurately transferred onto the receiving member 39 without being dispersed, and accurate bolt transfer is realized. Further, since there are a plurality of attracting bolts by the magnet 29, the bolt 1 moves in a group having a width orthogonal to the traveling direction. For this reason, even if the receiving member 39 is displaced in the vicinity of the movement path 35, the bolt can be transferred to the receiving member 39 as described above.

  By selecting the arrangement form of the orbiting member 17 and setting the movement path 35 set by the movement locus of the suction member 27 to the so-called large turning form in which the depth direction and the width direction of the storage container 9 are enlarged, the storage container 9 It is possible to increase the inner surface area of the transport substrate 12 that forms a part of the storage substrate 9, and to increase the storage volume of the storage container 9. That is, the capacity of the bolt 1 can be increased. In order to make the movement trajectory of the suction member 27 large, the storage volume of the storage container 9 can be appropriately selected by adjusting the length of the arm plate 32 serving as a distance piece.

  Since the suction member 27 circulates within a range of the outer area of the transport substrate 12 formed by one of the wall plates, the movable member can be compactly gathered along the transport substrate 12.

  The receiving member 39 of the rectilinear feeder 38 is disposed in the space portion at the corner where the transport substrate 12 and the protective plate 61 intersect, and the bolt 1 that has moved while sliding on the inner side surface 12B of the transport substrate 12 is located on the receiving member 39. Reach up. At this time, there is a possibility that the bolt 1 jumps outward from the receiving member 39 and falls, but such a bolt 1 is received by the protective plate 61 and the transport substrate 12 and does not fall. Therefore, the bolt 1 is reliably transferred to the receiving member 39 which is the start position of the linear feeder 38, and the transfer to the target position is achieved with high reliability.

  By arranging the guide plate 58 connected to the receiving member 39, even if the bolt 1 located at a location separated from the magnet 29 and weakened in attraction force is likely to fall, the bolt 1 remains on the guide plate 58. It moves while rubbing and reaches the receiving member 39 without dropping. In this way, as many bolts 1 as possible can be delivered to the receiving member 39. Further, since the guide plate 58 is installed, even if the receiving member 39 is deviated from the movement path 35, that is, even if the receiving member 39 is present in the vicinity of the movement path 35, the bolt 1 can be used. It slides down and reaches the receiving member 39, so that the bolt is surely moved.

  Since the rectilinear feeder 38 is disposed on the straight lateral side surface of the storage container 9, that is, outside the storage container 9 along the wall plate 15, the rectilinear feeder 38 and the storage container 9 can be compactly integrated. . Further, since the rectilinear feeder 38 is formed in a series of the receiving member 39, the suspending member 40, the selecting member 41, and the suspending member 42, the receiving of the bolt 1 and the removal of the abnormal bolt are smoothly achieved. .

  FIG. 7 shows a second embodiment of the present invention.

  In the first embodiment described above, the electric motor 19 protrudes from the storage container 9 in the direction of the rotation axis of the sprocket wheel 18, but in the second embodiment, the electric motor 19 is arranged next to the storage container 9. Thus, the protrusion as in the first embodiment is eliminated.

  An electric motor 19 and a speed reduction box 20 are arranged on the side of the storage container 9. A support member 36 is fixed to the support plate 11, and the deceleration box 20 is coupled thereon.

  FIG. 8 shows a third embodiment of the present invention.

  In this embodiment, the metal chain 17 is arranged in a triangular shape with rounded corners. In other words, the sprocket wheel 74 is newly added, and the metal chain 17 is stretched over the three sprocket wheels 18, 24 and 74.

  The sprocket wheels 18 and 74 are arranged below, and an expanded container space 75 is formed below the storage container 9. Here, the bottom member 10 has a flat plate shape. Other configurations are the same as those of the previous embodiments, including the portions not shown, and members having the same functions are denoted by the same reference numerals.

  With the above configuration, the container space 75 expanded below the storage container 9 is formed, and the capacity of the storage container 9 can be increased. Further, since the metal chain 17 between the sprocket wheels 18 and 74 is arranged in a substantially horizontal direction, the suction member 27 moves by attracting all the bolts 1 accumulated at the bottom of the enlarged container space 75. Is possible. Other functions and effects are the same as those of the previous embodiments.

  Furthermore, although not shown, drive means such as the electric motor 19 and the speed reduction box 20 can be disposed below the storage container 9 to operate the component supply device with a structure like the metal chain 73. .

  As a supply method, the suction member is moved along the outer surface of the transfer substrate by the rotating operation of the rotation member, and the component adsorbed on the inner surface of the transfer substrate is moved along the movement path along with the movement of the suction member. However, although the sucked component is received on the member, the effect is the same as that of the embodiment of the component supply apparatus.

  As described above, according to the apparatus of the present invention, parts can be reliably and efficiently conveyed, and the structure of the parts supply apparatus can be simplified. Therefore, it can be used in a wide range of industrial fields, such as an automobile body assembly process and a home appliance sheet metal assembly process.
