Description

  This invention relates to what is sent out from a conveyance passage board such as a parts feeder so as not to overlap flat plate-like parts.

In a conveyance passage plate such as a parts feeder that sends out a flat plate-like component, the component is sent from the component storage portion to the component delivery portion via the conveyance passage plate. A conveyance path plate of this type is known from Japanese Patent No. 3416770, which describes a passage restricting member for discriminating the front and back of the projection nut in the component delivery section.
Japanese Patent No. 3416770

  In the conveyance path plate as described above, the front and back of the projection nut can be discriminated, but nothing has been paid to preventing the flat plate-like component from overlapping in the vicinity of the component delivery unit.

  The present invention has been provided to solve the above-described problems, and an object of the present invention is to provide a component feeding portion of a conveyance path plate that can feed plate-shaped components without overlapping.

Means to solve the problem

  The invention according to the first aspect is to receive the outer peripheral portion of the flat plate-like component on the guide surface of the guide step portion provided at the lower portion of the conveyance passage plate, and send out from the conveyance passage plate so as not to overlap the components. A flat reference guide surface is formed on the component delivery portion in a state where the guide step portion is continuous, and a suction means for closely contacting the component to the reference guide surface is provided. The friction force is set so as to be lower than the feeding output by the feeding operation of the transport passage plate, and a feeding pipe is provided for allowing a part that is in close contact with the reference guide surface to pass through in a state of being continuous with the reference guide surface. It is a parts delivery part of a conveyance passage board.

The invention's effect

  The flat plate-like component moves while being in close contact with the reference guide surface by the suction means while being supported by the guide surface of the guide step portion. Accordingly, the component enters the delivery pipe in a state of being in close contact with the reference guide surface, and is thus smoothly delivered to the delivery pipe. Since the parts are sucked by the reference guide surface, the adjacent parts are brought into contact with each other because the outer peripheral portion abuts against each other, so that the overlapping phenomenon that one part enters under the other part does not occur. . If they overlap, the dimension in the thickness direction will be excessive, so the parts will not enter the delivery pipe and will be clogged in the opening of the delivery pipe, and the delivery of parts will stop. However, in the present invention, since the overlapping phenomenon is prevented as described above, such an adverse effect can be avoided.

  Since the frictional force of the component against the reference guide surface generated by the suction means is set so as to be lower than the feeding power by the feeding operation of the conveyance path plate, the feeding of the component is achieved while maintaining the contact state of the component. Then, parts are sent out while maintaining a state where there is no overlapping phenomenon. In addition, since the reference guide surface is a flat surface, the parts can be securely adhered to each other, and the abutting state of the outer peripheral part of the adjacent parts can be reliably obtained, which is effective for preventing the overlapping of the parts. .

  According to a second aspect of the present invention, a component dropping part is provided on the reference guide surface, and a width dimension of the guide surface in the component dropping part is set smaller than a width dimension of the guide surface upstream of the component dropping part. The parts delivery part of the conveyance passage plate according to claim 1.

  As described above, since the width dimension of the guide surface in the part dropping part is set smaller than the width dimension of the upstream guide surface, when the parts overlap, the parts that are in close contact with the reference guide surface are It is transported normally without falling. However, the other component that is in close contact with the component that is in close contact with the reference guide surface is not received from the lower side by the guide surface, and thus falls. Therefore, only the parts that are in close contact with the reference guide surface are normally delivered to the delivery pipe in the correct posture. Furthermore, even when a foreign object such as iron scrap is present between the reference guide surface and the part, the support of the guide surface at the part dropping part cannot be obtained normally, so the part falls. In this way, it is possible to reliably remove components that are not properly in close contact with the reference guide surface, and to prevent abnormal entry into the delivery pipe.

  According to a third aspect of the present invention, the width of the guide surface in the component dropping portion is set to be smaller than the thickness of the component. .

  By setting the width dimension as described above, the part support of the guide surface at the part drop part is made in a slight width region, so that the part falls reliably against abnormal conditions such as duplication and foreign matter inclusion, and operation reliability Sex can be kept high.

  According to a fourth aspect of the present invention, the suction means is disposed behind the conveying path plate on which the reference guide surface is formed. The parts of the conveying path plate according to any one of the first to third aspects Part.

  Since the suction means is arranged as described above, the component is reliably sucked to the reference guide surface. Further, since the suction force is applied to the parts from the back of the transport passage plate, the suction force can be efficiently applied to enable strong suction.

  According to a fifth aspect of the present invention, there is provided the component feeding portion of the conveyance path plate according to any one of the first to fourth aspects, wherein the attraction means is a magnet.

  By selecting the attractive force and the number of magnets, the frictional force with respect to the reference guide surface of the part adapted to the feeding power of the conveying passage plate can be obtained.

  The invention according to claim 6 is the parts feeding section of the conveyance path plate according to claim 5, wherein the magnet is housed in a housing recess provided in the holding member in a state in which a plurality of magnets are movable.

Thus, it is possible to obtain an optimal magnet arrangement for component attraction. Moreover, since the said holding member can be handled as a magnet unit, a magnet can be arrange | positioned in an optimal position by changing the arrangement position and direction of a holding member.

  According to a seventh aspect of the invention, the holding member is in a state of being pressed directly or indirectly through a shim member for adjusting the attractive magnetic force behind the conveyance path plate on which the reference guide surface is formed. It is a components delivery part of the conveyance channel | path board of Claim 6.

  Since the holding member is pressed directly behind the conveyance path plate or indirectly through a shim member for adjusting the attractive magnetic force, the magnet can be easily arranged at the optimum position only by the pressing structure of the holding member. . In addition, since the holding member is disposed behind the conveyance path plate, it is easy to freely adjust the gap between the magnet and the part, and the suction force adjustment and the assembly of the holding member are simplified.

  According to an eighth aspect of the present invention, a locking guide member for locking the upper end portion of the component is attached along the longitudinal direction of the conveyance path plate at a portion where the inclination angle of the conveyance path plate is large. It is a components delivery part of the conveyance channel | path board in any one of Claims 1-7.

  When the inclination angle of the transfer passage plate is increased, the components are also inclined such that they are close to a vertical standing state. Since the upper end portion of the component is locked by the locking guide member in such an inclined state, the component can be prevented from falling to the side away from the conveyance path plate, and normal component transfer is achieved.

  Next, the best mode for carrying out the component delivery section of the conveyance path plate of the present invention will be described.

  1 to 10 show a first embodiment.

  First, a flat plate component will be described.

  FIGS. 10A and 10B show parts to be supplied in this embodiment. This component 1 is made of iron, a disk 4 is formed using a flat steel plate, and a through hole 5 is formed in the center thereof. This is a normal washer. As for the dimensions of each part, the diameter is 20 mm, the inner diameter of the through hole 5 is 8 mm, and the thickness is 1.6 mm.

  Further, the component 1 shown in FIG. 9 is also a target in the present invention. A flat steel plate is formed into a circular shape, and three welding projections 2 that are projection-shaped members are provided on one side at intervals of 120 degrees. Is formed. In addition, the component 1 has a through hole 3 in the center thereof. The component 1 has a diameter of 35 mm, a thickness of the steel plate of 1 mm, a height of the welding projection 2 of 1 mm, and an inner diameter of the through hole 3 of 8 mm.

  Parts 1 as shown in FIGS. 10C and 10D can also be the subject of the present invention. In this case, welding projections 7 are formed at the four corners of a square plate 6 formed of a steel plate in a square shape.

  The welding protrusions 2 and 7 described above are welded to the counterpart member by electric resistance welding. Therefore, when it is sent out from a conveyance path plate such as a parts feeder, the direction of the welding protrusions 2 and 7 must be set to a predetermined direction. The thickness of the part includes the height of the welding protrusions 2 and 7. In each component 1, reference numeral 8 indicates an outer peripheral portion of the component. The outer peripheral portion 8 is an outer peripheral surface formed by the thickness of the component 1 and forms a state in which the outer peripheral portions 8 of the adjacent components 1 abut against each other in the component delivery portion and do not overlap.

  In this embodiment, the conveyance path plate is applied to the parts delivery path of the parts feeder.

  Therefore, the overall structure of the parts feeder will be described.

  FIG. 1A is a perspective view of the bowl of the parts feeder 9 as viewed obliquely from above, and FIG. 1B is a simplified side view of the parts feeder 9 as a whole. The parts feeder 9 is configured such that a vibration generating unit 11 is arranged below a circular bowl 10 which is a vibration conveying type, and parts are conveyed by vibrations generated by the vibration generating unit 11. This vibration is a composite of circumferential and vertical vibrations, and the component 1 is transferred in one direction by this combined vibration.

  1A is a cross-sectional view taken along the line (2)-(2) in FIG. 1A, FIG. 3 is a cross-sectional view taken along the line (3)-(3), and (5)-(5 ) It is illustrated in the same manner up to the sectional view.

  An outer plate 13 made of a steel plate is provided in a state of standing substantially on the outer periphery of the circular bowl 10, and a conveyance passage plate 14 is provided spirally along the inner side of the outer plate 13. The conveyance path plate 14 transfers the component 1 accumulated in the component storage portion 15 of the bowl 10 to a component delivery portion 16 that is an outlet portion of the parts feeder 9. The conveyance path plate 14 is provided with an inclination such that the outer peripheral portion is lower than the inner peripheral portion. As can be seen from FIGS. 2 to 5, the inclination angle of the inclination gradually increases as it approaches the component delivery unit 16. That is, the angle is gradually changed in the standing direction.

  A guide step portion 17 is disposed on the outer peripheral side of the transport passage plate 14, and a guide surface 18 is formed by this step structure. Due to the inclination of the conveying passage plate 14, the component 1 is moved toward the outer peripheral side, and at this time, the outer peripheral portion 8 of the component 1 is transferred while being received by the guide surface 18, as shown in FIGS.

  A delivery pipe 19 having a rectangular cross section is disposed on the downstream side of the parts delivery section 16, and the parts 1 are supplied to a target location by a synthetic resin supply hose 20 connected thereto. The cross-sectional shape of the delivery pipe 19 is shown in FIG. 8 and will be described in detail later.

  Next, the locking guide member will be described.

  When the inclination angle of the conveyance path plate 14 increases and the conveyance path plate 14 approaches a state where the conveyance path plate 14 stands in the vertical direction, the lower part of the component 1 is placed on the guide surface 18, and the upper part of the part 1 is the conveyance path. There is a risk of separation from the plate 14. Such a separation occurs because the bowl 10 is vibrating.

  Therefore, the upper part of the component 1 is locked to prevent the above-described separation, that is, the falling phenomenon of the component 1. Therefore, as shown in FIGS. 1A, 4 and 6C, a locking guide member 27 is attached to the upper portion of the transport passage plate 14 by welding or the like. The locking guide member 27 is a long member having an L-shaped cross section, and is disposed along the transport direction of the transport path plate 14. The cross-sectional shape of the locking guide member 27 is a shape having a passage space portion 28 and a locking piece 29, and the locking piece 29 engages the upper part of the component 1 even if the component 1 is likely to fall down due to conveyance vibration or the like. Since it stops, it is transported in a normal posture.

  Next, the component sending unit will be described.

  A reference guide surface 33 is formed on the conveyance path plate 14 in the component delivery section 16. The surface of the reference guide surface 33 is flat so that the component 1 can be in close contact therewith. A delivery pipe 19 is connected to the end of the conveyance path plate 14, and the reference guide surface 33 and the guide surface 18 are continuous inside the delivery pipe 19 as shown in FIG. The inclination angle of the transport passage plate 14 gradually increases as it approaches the reference guide surface 33, and the reference guide surface 33 stands up substantially in the vertical direction. As shown in FIG. 8B, the passage width W 1 of the delivery pipe 19 is set slightly larger than the thickness of the component 1. In this example, the passage width W1 is 2.0 mm with respect to the thickness of the component of 1.6 mm, so that even if the components are transferred in an overlapping state, they cannot enter the delivery pipe 19. It has become.

  Various structures can be adopted as the structure for forming the delivery pipe 19, but as shown in FIG. 8B, here, the cover plate 21 is fixed to the transport passage plate 14 with a bolt or the like to form a closed cross-section pipe structure. Is forming.

  Next, the suction means will be described.

  In order to bring the component 1 into close contact with the reference guide surface 33, suction means is disposed behind the transport passage plate 14 on which the reference guide surface 33 is formed. As this attraction means, various types can be employed, but here a magnet 34 is employed.

  As shown in FIGS. 7A, 7B, 7C, and 7D, a magnet 34 composed of a plurality of magnet pieces 30, 31, 32 is disposed. As shown in FIG. 7D, the magnet pieces 30, 31, and 32 are elongated members having a substantially square cross section. A holding member 35 is formed of an elongated rectangular stainless steel plate, and a receiving groove 36 as a receiving recess is formed at the center thereof. The magnet pieces 30, 31, and 32 are fitted in a state in which the magnet pieces 30, 31, and 32 are snugly fitted in the accommodation groove. The magnet pieces 30, 31, and 32 are movable along the longitudinal direction in the accommodation groove 36. By selecting the length of the positioning member 37 inserted into the end of the receiving groove 36, the positions of the magnet pieces 30, 31, 32 are selected. Such position adjustment is performed in order to obtain the most effective magnet position for the component 1 in the component delivery unit 16. That is, the position of the magnet 34 is selected according to the length of the positioning member 37 and the welding position. The positioning member 37 is made of a nonmagnetic material such as stainless steel and is welded to the end of the holding member 35.

  As shown in FIGS. 6A and 6D, the holding member 35 is directly behind the conveyance path plate 14 on which the reference guide surface 33 is formed or indirectly through a shim member 24 for adjusting the attractive magnetic force. It is supposed to be pressed. In the case of illustration, it is an indirect case through three shim members 24. The holding member 35 is pressed against the conveyance passage plate 14 by the pressing plate 25, and this pressing is performed by the pressurizing bolt 26. In order to arrange such a pressure bolt 26, a stationary support member 40 is disposed, and the pressure bolt 26 is screwed into the support member 40 and pressed. Reference numeral 41 denotes a lock nut for preventing loosening. The shim member 24, the holding member 35, the pressing plate 25, the storage box 43 described later, and the like are made of stainless steel that is a nonmagnetic material. Alternatively, a synthetic resin can be used.

  Various structures can be employed to arrange the stationary support member 40 as described above, but the storage box 43 is used here. The opening side of the storage box 43 is welded to the back surface of the conveyance path plate 14, and a shim member 24, a holding member 35, and a pressing plate 25 are inserted into the inside from the conveyance path plate 14 side, and fixed with the pressure bolts 26. Has been. Further, in order to prevent the positional deviation in the vertical direction, a pressing plate 44 is applied to the upper side of the holding member 35 and is pressed by the pressure bolt 45. In FIG. 6A, the illustration of the cover plate 46 is stopped to make the internal structure easy to understand.

  Since the necessary shim member 24, holding member 35, pressing plate 25 and the like are stored in the storage box 43 in this way, the magnet can be easily inserted by simply inserting the shim member 24 and the like into the storage box 43 in sequence. 34 can be arranged. Further, since the attraction force of the magnet 34 to the component can be finely adjusted by the shim member 24, the frictional force of the component 1 with respect to the reference guide surface 33 is set so as to be lower than the feeding output by the feeding operation of the transport passage plate 14. Easy to do.

  As shown in FIG. 6E, the region where the width dimension W2 of the guide surface 18 is set smaller than the thickness dimension T (1.6 mm) of the component 1 is defined as the component dropping portion 47. W2 is 1.0 mm. A storage box 43 is disposed at a position corresponding to the component dropping portion 47.

  Because of the dimensional relationship as described above, when iron scrap 48 is interposed between the reference guide surface 33 and the surface of the component 1 as shown in FIG. Drop off surface 18. Such a drop prevents the component 1 that is not properly in close contact with the reference guide surface 33 from entering the delivery pipe 19. Furthermore, as shown in FIG. 6G, when one component 1 is correctly attached to the reference guide surface 33 and is correctly received by the guide surface 18, another component 1 may overlap. However, since the overlapped parts 1 cannot be supported by the guide surface 18, they immediately fall.

  The component 1 dropped from the conveyance path plate 14 by the function of the component dropping portion 47 as described above is received by a receiving box 31 provided outside the conveyance path plate 14 and returned to the return passage 32 shown in FIGS. 4 and 5. And returned to the component storage unit 15.

  As another example of the suction means, an air suction method can be adopted as shown in FIG. 6 (H). An air suction port 38 opened on the surface of the reference guide surface 33 is connected to a suction pump (not shown) via an air hose 39. The component 1 is attracted to the reference guide surface 33 by this air suction.

  As shown in FIG. 8, a groove 22 extending in the transport direction is formed on the reference guide surface 33, thereby reducing the frictional resistance of the component 1 against the reference guide surface 33. Then, foreign matters such as rust preventive oil and iron scrap adhering to the component are accommodated in the groove 22 so that the component 1 is securely adhered to the reference guide surface 33. A similar groove 23 is also formed on the inner surface of the cover plate 21.

  The parts feeder 9 described above is of a type that vibrates the bowl 10, but instead of this, a magnet is assembled to an upright rotating disk and the parts adsorbed by the rotation of the disk are guided to the parts delivery passage. Can be. That is, this is a case where the conveyance path plate is applied to the component delivery path.

  Furthermore, it can replace with the parts feeder 9 which sends out the stored components, and can be a thing of the type guide | induced to the components delivery path | route of a linear feeder. That is, this is a case where the conveyance path plate is applied to the component delivery path. The linear feeder conveys parts continuously by giving vibrations of parts conveyance to a long member forming the parts delivery path, and conveys the washer 1 along such a parts conveyance path. Then, the “part feeding section of the conveyance path plate” according to the present invention is assembled. The straight feeder will be described in detail in the second embodiment.

  Next, the lines of magnetic force due to the arrangement of the magnets will be described.

  Various combinations can be selected as to which surface of each magnet piece 30, 31, 32 is to be given polarity. FIG. 7 is a diagram showing a positional relationship between the magnet 34 and the washer 1. As shown in FIG. 4D, an S pole or N pole is set on the elongated surface, and an N pole or S pole is set on the opposite elongated back surface. By giving such a polarity, a line of magnetic force of the form indicated by reference numeral 49 is formed and passes through the washer 1. The washer 1 is attracted to the reference guide surface 33 by passing the magnetic lines of force 49 through the washer 1.

  In FIG. 7D, the abutting portion of the magnet pieces 30 and 31 faces the central portion of the component 1 immediately before the delivery pipe 19 as shown in FIG. By setting such a positional relationship, the magnetic force lines 49 can be applied to the component 1 in a state where the magnetic flux density is higher, which is effective in enhancing the attractive force of the component 1.

  The magnet 34 shown in FIG. 7 (E) is composed of two magnet pieces 30 and 31, and the substantially square surface at the end in the longitudinal direction of each magnet piece 30 and 31 is made an S pole or an N pole. The magnetic field lines formed thereby are indicated at 50. As the magnetic field lines 50 pass through the washer 1, the washer 1 is attracted to the reference guide surface 33 in the same manner as described above.

  In the case shown in FIG. 7F, a large number of circular magnet pieces 51 are accommodated in the wide accommodation groove 36. The circular magnet piece 51 can be formed into a thick disk shape or a cylindrical shape.

  The magnet attraction force obtained as described above is adjusted by adjusting the magnetic force of the magnet pieces 30, 31, 32 themselves or by adjusting the number of the shim members 24, and thereby the reference guide surface. Thus, the frictional force of the part 1 with respect to 33 is set so as to be lower than the feed output by the feed operation of the transport passage plate 14.

  In the case where a predetermined attractive force can be obtained simply by adjusting the magnetic force of the magnet pieces 30, 31, 32 themselves without using the shim member 24, the holding member 35 is directly brought into close contact with the back surface of the conveyance path plate 14. Can do.

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

  The flat washer 1 moves while being in close contact with the reference guide surface 33 by the magnet 34 while being supported by the guide surface 18 of the guide step portion 17. Therefore, the washer 1 enters the delivery pipe 19 in a state of being in close contact with the reference guide surface 33, so that the washer 1 is smoothly delivered to the delivery pipe 19. And since the washer 1 is attracted | sucked by the reference | standard guide surface 33, since the adjacent washers 1 will be in the state which the outer peripheral part 8 contact | abutted and contacted, it seems that one washer 1 enters the lower side of the other washer 1. Duplicate phenomenon does not occur. If the overlap state occurs, the dimension in the thickness direction becomes excessive, so that the washer 1 cannot enter the delivery pipe 19 and the opening of the delivery pipe 19 is clogged, and the delivery of the washer 1 is stopped. However, in the present embodiment, since the overlapping phenomenon is prevented as described above, such an adverse effect can be avoided.

  Since the frictional force of the washer 1 with respect to the reference guide surface 33 generated by the magnet 34 is set so as to be less than the feeding output by the feeding operation of the transport passage plate 14, the component is maintained while maintaining the close contact state of the washer 1. The delivery is achieved, and the parts are delivered while maintaining a state where there is no overlapping phenomenon. Further, since the reference guide surface 33 is a flat surface, the washer 1 is securely adhered, and the abutting state of the outer peripheral portion 8 of the adjacent washer 1 is reliably obtained, so that the washer 1 is prevented from overlapping. It is effective for.

  Further, since the washer 1 stands substantially vertically, the weight of the washer 1 acts on the guide surface 18 of the guide step portion 17 but does not substantially act on the reference guide surface 33. Therefore, it becomes easy to finely control the attractive force of the magnet 34, and the washer applied to the parts feeder 9, that is, the transport passage plate 14, by appropriately setting the frictional force with respect to the reference guide surface 33 of the washer 1. The relationship with the transmission output of 1 is optimized. In other words, it is possible to minimize the frictional resistance against the component conveyance while maintaining the close contact of the washer 1 with the reference guide surface 33.

  A component dropping portion 47 is provided on the reference guide surface 33, and the width dimension W2 of the guide surface 18 in the component dropping portion 47 is the width dimension W3 of the guide surface 18 on the upstream side of the component dropping portion 47 (see FIG. 6C). ) Is set smaller.

  As described above, since the width dimension W2 of the guide surface 18 in the component dropping portion 47 is set smaller than the width dimension W3 of the upstream guide surface 18, when the washer 1 overlaps, the reference guide surface 33 is set. The washer 1 that is in close contact with is normally transferred without falling. However, the other washer 1 that is in close contact with the upper side of the washer 1 that is in close contact with the reference guide surface 33 is not received by the guide surface 18 from the lower side, and thus falls. Therefore, only the washer 1 that is in close contact with the reference guide surface 33 is normally delivered to the delivery pipe 19 in the correct posture. Further, even when a foreign object such as iron scrap 48 is interposed between the reference guide surface 33 and the washer 1, the support of the guide surface 18 in the component dropping portion 47 cannot be obtained normally. 1 falls. In this way, the washer 1 that is not properly in close contact with the reference guide surface 33 is reliably removed, and abnormal entry into the delivery pipe 19 is prevented.

  The width dimension W2 of the guide surface 18 in the component dropping part 47 is set smaller than the thickness dimension T of the washer 1.

  By setting the width dimension W2 as described above, the component support of the guide surface 18 in the component drop portion 47 is performed in a slight width region, so that the component is surely dropped against an abnormal state such as duplication or foreign matter inclusion. The operation reliability can be kept high.

  The suction means is disposed behind the transport passage plate 14 on which the reference guide surface 33 is formed.

  Since the suction means is arranged as described above, the washer 1 is reliably sucked to the reference guide surface 33. Further, since the suction force is applied to the washer 1 from behind the transport passage plate 14, the suction force can be effectively applied to enable strong suction.

  The attraction means is a magnet 34.

  By selecting the attractive force of the magnet 34 and the number of the magnet pieces 30, 31, 32, it is possible to obtain the frictional force with respect to the reference guide surface 33 of the washer 1 adapted to the feed output of the transport passage plate 14.

  The magnet 34 is accommodated in a state in which a plurality of magnet pieces 30, 31, and 32 can move in an accommodation recess or accommodation groove 36 provided in the holding member 35.

  Since the plurality of magnet pieces 30, 31, 32 are accommodated in the accommodation groove 36 in a movable state, the position where the magnetic lines of force 49, 50 are formed with respect to the washer 1 by selecting the polarity arrangement, Thus, it is possible to freely select the direction of the magnetic lines 49 and 50 with respect to the washer 1 to obtain an optimum magnet arrangement for component attraction. Further, since the holding member 35 can be handled as a magnet unit, the magnet 34 can be arranged at an optimum position by changing the arrangement position and orientation of the holding member 35.

  The holding member 35 is in a state of being pressed directly or indirectly through the shim member 24 for adjusting the attractive magnetic force behind the transport passage plate 14 on which the reference guide surface 33 is formed.

  Since the holding member 35 is pressed directly behind the transport passage plate 14 or indirectly through the shim member 24 for adjusting the attractive magnetic force, the magnet 34 can be easily placed at the optimum position by only the pressing structure of the holding member 35. Can be arranged. In addition, since the holding member 35 is disposed behind the conveyance path plate 14, it is easy to freely adjust the distance between the magnet 34 and the washer 1, and the suction force adjustment and assembly of the holding member 35 are simplified. Is done.

  Furthermore, by using the storage box 43, the placement of the magnet 34 is completed by simply inserting the shim member 24, the holding member 35, the pressing plate 25, etc. into the storage box 43 in sequence. Therefore, the magnet placement operation is simplified, and the replacement operation of the magnet 34 can be easily performed.

  A locking guide member 27 that locks the upper end portion of the washer 1 is attached along the longitudinal direction of the transport path plate 14 at a portion where the inclination angle of the transport path plate 14 is large.

  When the inclination angle of the transfer passage plate 14 is increased, the washer 1 is also in an inclined state that is close to a vertical standing state. Since the upper end portion of the washer 1 is locked by the locking guide member 27 in such an inclined state, it is possible to prevent the washer 1 from falling to the side away from the conveyance path plate 14 and normal component transfer is achieved. The

  The conveyance passage plate 14 is a member that forms a component delivery passage of the parts feeder 9.

  With the above configuration, the washer 1 delivered from the parts feeder 9 normally enters the delivery pipe 19 without overlapping, and the parts feeder 9 with high operational reliability is obtained.

  FIG. 11 shows a second embodiment.
