An entrance passage 6 is provided on the lateral side surface of the case body 1, and a part passage member 7 having a rectangular cross section communicated with the entrance passage 6 is welded to the case body 1. The shaft-like component 5 that has entered the case body 1 through the component passage member 7 and the inlet passage 6 is received by the transfer member 8 and is transferred toward the outlet passage 9 formed in the lid member 3. ing. The transfer member 8 is inserted into the case main body 1 so as to be able to advance and retreat.

Japanese Patent No. 2521557

  The state shown in the figure shows that the shaft-like component 5 introduced into the housing recess 12 is waiting at the delivery position as shown in FIG. Here, when compressed air is jetted from the air injection port 13 and the air flow hits the lower end surface of the part, the part rises, but at the same time as this rises, the air radiates and spreads in all directions, and the sliding It leaks toward the inlet passage 6 and the air cylinder 10 through the gap L. That is, air leaks through the sliding gap L of people.

  Since the air flow due to such air leakage is made in a narrow sliding gap of people, continuous noise such as “shoes” is generated greatly, which is not preferable in terms of factory environment. Moreover, the air flow rate increases, which is not preferable from the viewpoint of energy saving. Furthermore, since the air pressure acting on the parts decreases and it takes a long time for the delivery speed to increase, the delivery efficiency cannot be improved sufficiently. In particular, in the case of pneumatic conveyance, it is important that the initial speed reaches a predetermined speed in a short time. If this is insufficient, high-speed conveyance is impossible. And since the air injection port is formed in a part of the case main body, there arises a problem that it is difficult to blow air onto the optimal part of the part. Furthermore, it is indispensable to always keep the distance between the air injection port and the component in the shortest state in order to ensure an appropriate initial speed.

  The present invention has been provided to solve the above-described problems, and an object of the present invention is to provide a component delivery device that can efficiently deliver components with air leakage minimized.

According to the first aspect of the present invention, an advancing / retracting type transfer member is inserted into the case main body, and a shaft-shaped component receiving recess provided in the transfer member is formed at a location matching the inlet passage of the case main body. In a type in which an exit passage in which the housing recess matches by moving a predetermined distance is provided in the case body,
An air injection port for sending out the shaft-shaped component in the housing recess from the outlet passage by air injection is located at the bottom of the housing recess in the axial direction of the shaft-shaped component through the air passage formed in the transfer member. It opens toward the lower surface, and the receiving recess is shifted to the side opposite to the direction in which the shaft-shaped component enters the receiving recess from the position of the center line of the transferring member in the same direction as the forward and backward movement of the transferring member. When the transfer member moves a predetermined distance and matches the outlet passage, the housing recess becomes a space sealed by the inner surface of the case body, and this space communicates only with the outlet passage except for the air injection port. The component delivery device is configured as described above.

  Since the air for delivery is injected into the housing recess through the air passage formed in the transfer member, the leaked air passage is slightly between the opening periphery of the housing recess and the inner surface of the case body. Only the sliding gap in the proper area is obtained. As described above, since there are only a few air leaks, the noise associated with the air circulation described above is significantly reduced. At the same time, since the amount of air leaking is small, the consumption of compressed air can be saved.

  By reducing the amount of air leaked, the air pressure behind the part can be set high, thereby rapidly increasing the part delivery speed, increasing the so-called initial speed, and delivering the part quickly, and high-speed conveyance. Can be achieved to improve the transmission efficiency.

  Since the air injection port opens toward the housing recess, setting the opening location and direction according to the component shape, component mass, etc. reduces the amount of air to be injected and speeds up component delivery. This makes it possible to improve the delivery efficiency and reduce the consumption of compressed air. By selecting the opening location of the air injection port, it is also possible to cause the injection air to act on the component as a dynamic pressure, thereby realizing faster component delivery.

The receiving recess has a structure in which only a portion matching the inlet passage and a portion where parts are sent out from the receiving recess are opened, and the receiving recess is blocked by the inner surface of the case body when the transfer member moves by a predetermined distance. This space is configured to communicate with the outlet passage .

  Therefore, as described above, the passage portion of the air leaking from the housing recess moved a predetermined distance is only a small sliding gap between the opening peripheral portion of the housing recess and the inner surface of the case body, and the sealed housing. The recessed space communicates with the outlet passage. Therefore, the housing recess moved by a predetermined distance becomes a space having a good sealing property, and the air injected into the housing recess is effectively blown against the component under a situation where the amount of leakage is small.

The Yes air supply tube connected to the air passage so as to protrude to the outside from the through hole provided in the case body, the through hole is set to a size to allow the forward and backward displacement of the air supply pipe due to the forward and backward movement of the transfer member Tei Ru.

  With such a configuration, the air supply pipe follows the forward / backward movement of the transfer member and moves in the through hole, so that air is reliably injected into the housing recess. Since the air supply pipe is joined to the transfer member, the location of the air leak is only a slight sliding gap between the peripheral portion of the opening of the housing recess and the inner surface of the case body.

  Hereinafter, the form for implementing the components sending out device of the present invention is explained.

  1 to 5 show a first embodiment.

  The parts to be sent will be described.

  Examples of the parts sent out in the present invention include various types such as a cylindrical shaft-shaped part as shown in FIG. 9, a rectangular parallelepiped square part, and a part such as a nut. Here, the flanged shaft-like component 20 shown in FIG. 1C is made of iron. This is composed of a shaft portion 21 in which a male screw is formed, a circular flange 22 formed integrally with the shaft portion 21, and a circular welding projection 23 formed in the center portion of the flange 22. This component is a projection bolt welded to a steel plate component or the like by electric resistance welding. The dimensions of each part are as follows: the diameter and length of the shaft part 21 are 5 mm and 14 mm, the diameter and thickness of the flange 22 are 14 mm and 1.2 mm, respectively, and the diameter and protrusion height of the welding protrusion are 8 mm and 1.3 mm. is there.

  Next, the overall structure of the component delivery device will be described.

  FIG. 1A is a plan view of the entire apparatus, and is illustrated with a lid member 26 described later removed in order to facilitate understanding of the internal structure. A flat upper surface 25 is formed in a box-shaped case body 24 having a substantially rectangular parallelepiped shape, and a plate-like lid member 26 is in close contact with a bolt (not shown) as shown in FIG. It is fixed. In addition, the code | symbol 27 shown to FIG. 1 (A) is a screw hole of the said volt | bolt. Note that FIG. 3A is a cross-sectional view of (3)-(3) in FIG.

  An inlet passage 28 is provided on the lateral side of the case body 24, and a component passage member 29 is welded to the case body 24 in a continuous state. As shown in FIG. 2B, the component passage member 29 is of a type that transports the shaft-shaped component 20 in a suspended state, and is formed on the upper surface of the U-shaped member 31 opened upward and on the lower surface of the flange 22. Is formed, and a passage space 33 through which the shaft portion 21 passes is formed. Therefore, the shaft-like component 20 is transferred to the inlet passage 28 in a suspended state as shown in FIG. The parts passage member 29 extends from the parts feeder 34.

  The inlet passage 28 includes a sliding surface 35 continuous with the sliding surface 32 and a passage space 36 continuous with the passage space 33 so that the shaft-like component 20 from the component passage member 29 can smoothly enter. Has been. The sliding surface 35 is formed with a step portion 37 on the upper surface portion of the case body 24 so that the lower surface of the flange 22 can slide in the same direction when a transfer member 38 to be described later moves.

  Next, the transfer member will be described.

  The transfer member 38 is formed by processing a square block-shaped member. A housing recess 40 for receiving the shaft-like component 20 is formed in a state opened to the side of the transfer member 38. As shown in FIG. 4C, the housing recess 40 includes a small recess 41 that receives the shaft portion 21 and a large recess 42 that receives the flange 22. As shown in FIGS. 1, 2, and 4, the back portion of the small recess 41 has an arc-shaped cross-sectional shape that receives the shaft portion 21. Only the portion on the inlet passage 28 side and the portion on the side communicating with the outlet passage 58 described later are opened in the housing recess 40. A flat support surface 44 formed at the boundary between the small recess 41 and the large recess 42 is formed in a state of being smoothly continuous with the sliding surface 35 described above, and supports the flange 22.

  As shown in FIG. 3, the transfer member 38 is inserted into the case main body 24 so as to advance and retreat while sliding on the inner surface of the case main body 24, and the piston rod 46 of the air cylinder 45 coupled to the case main body 24 transfers the transfer member 38. Coupled to the end of member 38. The transfer member 38 advances and retreats in the left-right direction in FIG. 1A and in the direction perpendicular to the paper surface in FIG.

  Next, the insertion recess will be described.

  The vertical direction in FIG. 1A is the width direction of the transfer member 38, and the center line OO is the same as the forward / backward direction of the transfer member 38. This center line OO is the center position of the transfer member 38. The accommodating recess 40 is arranged so as to be shifted toward the inlet passage 28 from the center position of the transfer member 38. An insertion recess 48 is formed in a portion of the transfer member 38 opposite to the inlet passage 28. The insertion recess 48 is a groove-like portion extending in the same direction as the forward / backward direction of the transfer member 38. The back portion of the insertion recess 48 reaches close to the small recess 41, thereby forming a thin portion 49.

  The insertion recess 48 has a groove shape in cross section, but as shown in FIG. 3C, it is also possible to form the housing recess 48 in a notch shape instead of a groove shape.

  Next, the magnet will be described.

  An insertion hole 50 is formed in the back plate 47 of the case main body 24, and an elongated long permanent magnet 52 is penetrated there. And the front-end | tip part of the permanent magnet 52 is located in the vicinity of the said thin part 49. FIG. The base end portion 53 of the permanent magnet 52 is welded to a fixed piece 54, and this fixed piece 54 is coupled to the back plate 47 with a bolt 55. With such a magnet arrangement, the tip of the magnet 52 is positioned close to the shaft-shaped component 20 in the housing recess 40. In order to set such a positional relationship, a magnet 52 is arranged on an extension line in the entrance direction of the shaft-like component 20 in the inlet passage 28. That is, the inlet passage 28 and the permanent magnet 52 are opposed to each other on both sides of the case body 24.

  As shown in FIG. 4A, the permanent magnet 52 is formed by arranging five permanent magnets and enclosing them in an elongated container 56. The polarities of the portions where the magnets arranged in close contact with each other are in a reverse polarity relationship such as S vs. N. Therefore, the magnetic field lines of the entire permanent magnet 52 are in the form indicated by reference numeral 57, and the magnets attract each other.

  Next, the exit passage will be described.

  The above-described outlet passage 58 is formed at a position where the accommodation recess 40 is matched by the movement of the transfer member 38 by a predetermined distance. Here, it is a through-hole opened in the lid member 26, and is shown by a two-dot chain line in FIG. 3 (A) and in FIG. 4 (E). A supply passage pipe 59 is connected to the outlet passage 58, and the shaft-like component 20 reaches the target location through the supply passage pipe 59. The supply passage pipe 59 is also indicated by a two-dot chain line in FIG. In addition, the cross-sectional state which shows the state in which the accommodation recessed part 40 corresponds to the exit channel | path 58 in this way is the same as FIG.

  As shown in FIG. 2, a receiving surface 60 that receives the flange 22 of the next shaft-shaped component 20 when the transfer member 38 moves to the outlet passage 58 side is formed.

  When the accommodating recess 40 moves a predetermined distance and matches the outlet passage 58, the accommodating recess 40 is sealed by the inner surface 61 of the case body 24, and becomes a closed space in a state of communicating only to the outlet passage 58 side.

  Next, air injection will be described.

  In order to send out the shaft-shaped component 20 in the housing recess 40, an air injection port 63 is opened into the housing recess 40. The air injection port 63 opens into the housing recess 40 through an air passage 64 provided in the transfer member 38. This opening is arranged at the bottom of the small recess 41, and the air jet from here is blown directly onto the lower surface of the shaft portion 21. Accordingly, the dynamic pressure of the blast air acts positively on the shaft-like component 20.

  An air supply pipe 65 is welded to the air passage 64, and the air supply pipe 65 goes out through a through hole 66 formed in the back plate 47 of the case body 24. The through hole 66 is set to a size that allows the air supply pipe 65 to move forward and backward as the transfer member 38 moves forward and backward. Therefore, as shown in FIG. 4D, when the back plate 47 is viewed from behind, the through hole 66 has a horizontally long shape extending in the forward and backward direction of the transfer member 38. The insertion hole 50 is located above the through hole 66.

  Since the air for delivery is injected into the housing recess 40 through the air passage 64 formed in the transfer member 38, the leaked air passage is located at the opening peripheral portion 67 of the housing recess 40 and the inner surface of the case body. Only a sliding gap in a small area between 61 and 61 is obtained. In FIG. 4C, the region is indicated by a two-dot chain line, and this is an opening peripheral portion 67. In this way, the number of air leakage locations is greatly reduced as compared with the case described with reference to FIG. 9, which is useful for reducing noise accompanying air leakage and reducing air consumption.

  When the component delivery device for delivering the projection bolt 20 having the dimensions as described above has a structure as shown in FIG. 9, the noise at a location 1 m away from the device was 88 decibels. On the other hand, the noise of the component delivery device in which the housing recess 40 and the air passage 64 are formed as in this embodiment is 72 decibels at the same location 1 m away, and noise reduction is achieved by minimizing the air leakage location. Significant improvement was observed. Similarly, the amount of air consumed is also reduced.

  As shown in FIG. 3B, the air injection port 63 can be opened from the side of the small recess 41. In this case, the static pressure is more dominant than the dynamic pressure with respect to the shaft portion 21. Since there is little air leakage from the opening peripheral part 67, it becomes possible to make effective use of a static pressure in this way. Furthermore, the air supply pipe 65 connected to the transfer member 38 can be extended directly below the case main body 24, and in this case, a through hole 66 is provided on the lower side of the case main body 24.

  In the above-described first embodiment, the jet air heading into the housing recess 40 is used as the preliminary air jet, and the air jet transported to the target location is transferred to the shaft-like component 20 that has reached the supply passage pipe 59 by the preliminary air jet. Main air injection can be used. As shown by a two-dot chain line in FIG. 3A, an air pipe 62 for supplying air for main air injection is connected to the supply passage pipe 59.

  In order to strongly apply the magnetic force of the permanent magnet 52 to the shaft-shaped component 20, the material constituting the entire case main body 24, the transfer member 38, the fixed piece 54, the container 56, and the like is a non-magnetic material such as stainless steel or synthetic resin. Used. Here, it is stainless steel.

  Note that, instead of the air cylinder 45 described above, an electric motor that outputs and retreats may be employed.

  Next, a modified example of the magnet arrangement will be described.

  FIG. 5 shows a modification of the structure in which a magnetic force is applied to the shaft portion 21. FIG. 5A shows a case where the shaft portion 21 is long, and two permanent magnets 52 are arranged for this purpose. The other configuration is the same as that of the structure of FIG. 3 including a portion not shown, and members having the same function are denoted by the same reference numerals.

  In FIG. 5B, the insertion recess 48 is eliminated, and a permanent magnet 52 is attached to the case main body 24 at a location facing the inlet passage 28, and a magnetic attraction member 69 magnetized by this magnet serves as a transfer member. 38, and the tip of the magnetic attraction member 69 is disposed close to the shaft 21 in the small recess 41. The magnetic attraction member 69 is made of a magnetic material, and the shape thereof is a long and narrow bar, and is made of iron. The lines of magnetic force formed by the magnetic attraction member 69 are the same as those shown in FIG. The other configuration is the same as that of the structure of FIG. 3 including a portion not shown, and members having the same function are denoted by the same reference numerals. 5D is obtained by replacing the permanent magnet 52 in FIG. 5B with an electromagnet 70. FIG. The other configuration is the same as the structure of FIG. 5B and FIG. 3 including a portion not shown, and members having the same function are denoted by the same reference numerals.

  In FIG. 5C, the exciting iron core 71 of the electromagnet 70 attached to the transfer member 38 is used as the magnetic attraction member 69, and the tip of the magnetic attraction member 69 is arranged close to the shaft-like component 20 in the housing recess 40. It is a thing. The electromagnet 70 is arranged in a state of being embedded in the transfer member 38, and the electric wire 72 to the electromagnet 70 passes through the through hole 73. The through hole 73 is formed to be elongated like the through hole 66 in order to follow the advancement and retraction of the transfer member 38. The lines of magnetic force formed by the electromagnet 70 are the same as those shown in FIG. Other configurations are the same as the structures of FIGS. 5B, 5D, 3 and the like, including portions not shown, and members having similar functions are denoted by the same reference numerals.

  FIG. 5E shows the tip of the magnetic attraction member 69 shown in FIG. The other configuration is the same as the structure of FIG. 5B and FIG. 3 including a portion not shown, and members having the same function are denoted by the same reference numerals.

  Next, the operation of the component delivery apparatus in the first embodiment will be described.

  FIG. 1A shows a state in which the housing recess 40 matches the inlet passage 28 and the shaft-like component 20 is introduced into the housing recess 40. In such a position of the transfer member 38, the tip of the magnet 52 is positioned close to the shaft-shaped component 20, so that the shaft-shaped component 20 is drawn into the housing recess 40 with a strong suction force. Then, the movement of the air cylinder 45 moves the transfer member 38 to the left, and the accommodation recess 40 matches the outlet passage 58. This matched state is shown in FIG. When the carrier air is ejected from the air ejection port 63 in this state, the shaft-like component is sent upward in FIG. 3A and is transferred through the supply passage tube 59 to reach the target location.

  Further, when the shaft-like component 20 passes through the outlet passage 58 and moves into the supply passage tube 59, it is also possible to perform main air injection from the air tube 62 so that the shaft-like component 20 reaches the target location at high speed. It is.

  The above-described operation can be easily performed by a generally employed 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.

  6 to 8 show a second embodiment.

  In the second embodiment, a shaft-shaped part that has entered from one inlet passage is received in a plurality of receiving recesses and is sent out from a plurality of outlet passages.

  As shown in FIGS. 6 and 7, the transfer member 38 is provided with two accommodating recesses 40, and the distance between them is S. FIG. 7 is a plan view in which the location of the air passage 64 is traversed. The air injection port 63 opened in each housing recess 40 and the air passage 64 formed in the transfer member 38 are the same as in the first embodiment. The air supply pipe 65 connected to these air passages 64 extends to the outside from an elongated through hole 66 provided in the back plate 47.

  As shown by a two-dot chain line in FIG. 7, two supply passage pipes 59 joined to the outlet passage 58 are disposed, and the interval dimension is twice the dimension S, which is indicated as 2S in the drawing. It is. The inlet passage 28 is located at the center of the distance dimension 2S.

  As shown in FIG. 8, a main air injection port 74 is opened in the vicinity of the outlet passage 58 in order to transfer the shaft-shaped component 20 that has entered the supply passage pipe 59 from the outlet passage 58 to the target location at a high speed. An air pipe 62 is connected to this. The main air injection port 74 is open to both supply passage pipes 59. And the said air injection port 63 in Example 1 is made into the preliminary | backup air injection port 63 here.

  FIG. 8 also shows an operation system diagram for performing air injection and the operation of the transfer member 38. Compressed air from the air pump 76 is supplied to the air passage 64, the air injection port 74, and the air cylinder 45 through the air switching valve 77, and a control device 78 that controls the air switching valve 77 is installed. . The control device 78 uses a normal sequence circuit or a simple computer device. Various signals necessary for transmitting the control signal are input to the control device 78, and a position signal indicating where the transfer member 38 is stopped is also input. Further, the air injection from the preliminary air injection port 63 is a short time until the shaft-like component 20 reaches the supply passage pipe 59, and the injection time is set by a timer device built in the control device 78. The air injection timing from the main air injection port 74 is made after a predetermined time has elapsed from the air injection start timing from the auxiliary air injection port 63. The elapse of the predetermined time is counted by the timer device.

  In the second embodiment, the number of the accommodating recesses 40 is two, but it is also possible to increase the number to three and four. Other configurations are the same as those of the first embodiment including the portions not shown, and members having the same functions are denoted by the same reference numerals.

  Next, the operation of the component delivery apparatus according to the second embodiment will be described.

  FIG. 6 shows a state in which the left receiving recess 40 is aligned with the inlet passage 28, and the shaft-like component 20 (not shown in FIG. 6) is introduced by the permanent magnet 52. Here, the air cylinder 45 driven by the operation of the control device 78 moves the transfer member 38 to the left, and the accommodation recess 40 matches the supply passage pipe 59 on the left side of FIG. In this coincidence state, the accommodation recess 40 has an air leakage portion minimized in the peripheral portion 67 of the opening, so that the jet air from the preliminary air injection port 63 is effectively applied to the shaft-like component 20 in a state where the leakage amount is small. Sprayed from the outlet passage 58 to the supply passage pipe 59. At this time, the air for conveyance is injected from the main air injection port 74, and the shaft-shaped component 20 is transferred to the target location. Thus, when the shaft-shaped component 20 is delivered from the left receiving recess 40, the right receiving recess 40 matches the inlet passage 28, and the components are received.

  Thus, when the air injection from the main air injection port 74 is started, the transfer member 38 is immediately shifted to the right side, and the state shown in FIG. 6 is obtained. Therefore, this time, the right receiving recess 40 is aligned with the right supply passage pipe 59, and the same feeding as the above-described operation is performed. As described above, the shaft-like component 20 is sent from the housing recess 40 to the supply passage pipe 59 and air injection is started from the main air injection port 74, and at the same time, the transfer member 38 switches and moves. As a result, when the shaft-shaped component 20 is moving along the long supply passage pipe 59, the next shaft-shaped component 20 is introduced into the receiving recess 40, and this is then delivered from the other supply passage tube 59. . Therefore, the time during which the shaft-like component 20 passes through the supply passage pipe 59 can be saved, and an efficient operation of the component delivery device can be obtained.

  The operational effects of the first embodiment and the second embodiment are as follows.

  The tip of the magnet 52 that has entered the insertion recess 48 is positioned close to the shaft-shaped component 20 in the storage recess 40 when the storage recess 40 is aligned with the inlet passage 28. Therefore, the component suction force into the housing recess 40 can be applied strongly, and the shaft-like component 20 is reliably introduced into the housing recess 40. Since the shaft portion 21 has a small diameter, even if it is a small receiving recess 40 (small recess 41), the permanent magnet 52 can enter the insertion recess 48 and the tip of the magnet can be positioned close to the shaft portion 21. Part suction is performed reliably. For example, when the diameter of the shaft-shaped component 20 is small, the state in which the magnet tip is close to the shaft portion 21 can be ensured in this way, so that the attractive force to the shaft-shaped component 20 can be applied appropriately.

  Furthermore, since the insertion recess 48 is arranged in the same direction as the advancing and retreating direction of the transfer member 38, the transfer member 38 can be freely advanced and retracted while the magnet 52 is in the state of entering. In a state where the transfer member 38 moves by a predetermined distance and the accommodation recess 40 is aligned with the outlet passage 58, no attracting magnetic force acts on the shaft-shaped component 20 in the accommodation recess 40. The frictional force between the inner surface of the recess disappears. Accordingly, it is possible to minimize the pressure of the jet air to the housing recess 40 and the air flow rate, which is effective for reducing the jet air and reducing the air noise.

  The magnet 52 has a long shape, and the base end portion 53 is fixed to the back plate 47 of the case main body 24.

  Therefore, it is possible to insert the tip of the insertion recess 48 to the back with a long magnet shape, and to position the tip portion close to the shaft portion 21 with certainty. Furthermore, since the base end portion 53 of the magnet 52 is fixed to the case main body 24, the relative position between the inlet passage 28 of the case main body 24 and the magnet 52 can be accurately set in a state of being opposed to each other.

  The housing recess 40 is formed by being shifted from the center position OO of the transfer member 38 toward the inlet passage 28, and the insertion recess 48 is formed at a portion opposite to the inlet passage 28.

  In this way, the housing recess 40 is formed by being shifted toward the inlet passage 28 from the center line OO in the same direction as the forward / backward direction of the transfer member 38, that is, the center position seen in the width direction of the transfer member 38. On the opposite side, an insertion recess 48 having a space required for magnet insertion can be reliably formed.

  The part to be delivered is a flanged shaft-like part 20 in which the flange 22 and the shaft part 21 are integrated, and the sliding surface 35 and the shaft part 21 on which the lower surface of the flange slides pass through the inlet passage 28. A passage space 36 is provided.

  Therefore, the shaft-like component 20 is slid on the lower surface of the flange and passed through the space of the shaft portion 21 and smoothly passes through the inlet passage 28 and is introduced into the housing recess 40.

  The component delivery device is of a type that eliminates the insertion recess 48, and an advancing / retracting transfer member 38 is inserted into the case body 24. An outlet passage 58 is formed in the case body 24 so as to match the receiving recess 40 when the transfer member 38 moves by a predetermined distance, and the part 20 is sucked into the receiving recess 40. In the type in which a magnet is disposed, a magnet 52 is attached to the case body 24 at a location opposite to the inlet passage 28, and a magnetic attraction member 69 magnetized by the magnet 52 is attached to the transfer member 38. The component delivery device is characterized in that the tip of the suction member 69 is disposed in the vicinity of the component 20 in the housing recess 40.

  When the accommodating recess 40 is aligned with the inlet passage 28, the magnetic lines of force 57 formed by the magnet 52 pass through the accommodating recess 40 through the magnetic attraction member 69. As a result, the magnetic lines of force 57 reach the component 20 that has entered the inlet passage 28, and the component 20 is attracted into the accommodating recess 40. Therefore, the component suction force into the housing recess 40 can be exerted strongly, and the component 20 is reliably introduced into the housing recess 40. Since the shaft portion 21 has a small diameter, even if the housing recess 40 is small, the tip portion of the magnetic attraction member 69 is located close to the shaft portion 21, so that component suction is reliably performed. For example, when the diameter of the shaft-shaped component 20 is small, the state in which the tip of the magnetic attracting member 69 is close to the shaft 21 can be ensured in this way, so that the attractive force on the component 20 can be applied appropriately. .

  Further, in a state where the transfer member 38 moves by a predetermined distance and the accommodation recess 40 matches the outlet passage 58, no attracting magnetic force acts on the component 20 in the accommodation recess 40, so the shaft portion 21 and the inner surface of the accommodation recess The frictional force between the two has disappeared. Therefore, the pressure of the blast air and the air flow rate with respect to the component 20 in the housing recess 40 can be minimized, which is effective for reducing the blast air and reducing the air noise.

  The accommodating recess 40 is formed by shifting toward the inlet passage 28 from the center position OO of the transfer member 38, and the magnetic attraction member 69 having a long shape is formed at a portion opposite to the inlet passage 28. Has been placed.

  In this way, the housing recess 40 is formed by being shifted toward the inlet passage 28 from the center line OO in the same direction as the forward / backward direction of the transfer member 38, that is, the center position seen in the width direction of the transfer member 38. A member dimension for arranging the magnetic attraction member 69 is secured in the portion of the transfer member 38 on the opposite side, and the magnetic attraction member 69 can be reliably arranged.

  This is a component delivery device of a type using an electromagnet 70, and an advancing / retracting transfer member 38 is inserted into the case main body 24, and the housing recess 40 of the shaft-like component 20 provided on the transfer member 38 is an inlet of the case main body 24 An exit passage 58 is formed in the case main body 24 at a position that matches the passage 28, and the transfer recess 38 moves by a predetermined distance to match the receiving recess 40, and a magnet that attracts the component 20 into the receiving recess 40. In the arrangement type, the exciting iron core 71 of the electromagnet 70 attached to the transfer member 38 is a magnetic attraction member 69, and the tip of the magnetic attraction member 69 is close to the shaft portion 21 in the housing recess 40. A component delivery device characterized by being arranged.

  When the accommodation recess 40 is aligned with the entrance passage 28, the magnetic lines of force 57 formed by the electromagnet 70 pass through the small recess 41 through the exciting iron core 71 that is the magnetic attraction member 69. As a result, the magnetic line of force 57 reaches the shaft portion 21 that has entered the inlet passage 28, and the shaft portion 21 is attracted into the housing recess 40. Therefore, the component suction force into the housing recess 40 can be exerted strongly, and the component 20 is reliably introduced into the housing recess 40. Since the shaft portion 21 has a small diameter, even if it is a small receiving recess 40, the tip portion of the magnetic attraction member 69 (excitation core 71) is located close to the shaft portion 21, so that component suction is reliably performed. . For example, when the diameter of the shaft-shaped component 20 is small, the state in which the tip of the magnetic attraction member 69 is close to the component 20 can be ensured in this way, so that the attractive force to the component 20 can be applied appropriately.

  Further, when the transfer member 38 moves by a predetermined distance and the accommodation recess 40 matches the outlet passage 58, the energization to the electromagnet 70 is stopped and the attractive magnetic force disappears. In this state, since the attractive magnetic force does not act on the component 20 in the housing recess 40, the frictional force between the component 20 and the inner surface of the housing recess 40 has disappeared. Therefore, the pressure of the blast air and the air flow rate with respect to the component 20 in the housing recess 40 can be minimized, which is effective for reducing the blast air and reducing the air noise.

  Since the air for delivery is injected into the accommodation recess 40 (small recess 41) through the air passage 64 formed in the transfer member 38, the leaked air passage location is the periphery of the opening of the accommodation recess 40. There is only a slight sliding gap between 67 and the inner surface 61 of the case body. As described above, since there are only a few air leaks, the noise associated with the air circulation described above is significantly reduced. At the same time, since the amount of air leaking is small, the consumption of compressed air can be saved.

  By reducing the amount of leaked air, the air pressure behind the part can be set high, thereby rapidly increasing the delivery speed of the part 20, increasing the so-called initial speed, and delivering the part quickly. The conveyance can be realized and the transmission efficiency can be improved.

  And since the air injection port 63 is opening toward the accommodation recessed part 40 (small recessed part 41), by setting this opening location and opening direction according to component shape, component mass, etc., the amount of injection air is set. The parts can be sent at a high speed with a reduced amount, and the sending efficiency can be improved and the consumption of compressed air can be reduced. By selecting the opening location of the air injection port 63, it is also possible to cause the injection air to act on the component 20 as a dynamic pressure, thereby realizing faster component delivery.

  The accommodation recess 40 has a structure in which only a portion that matches the inlet passage 28 and a portion where the component 20 is sent out from the accommodation recess 40 are opened, and when the transfer member 38 moves a predetermined distance, The space was sealed by the inner surface 61 of the case body 24, and this space was configured to communicate with the outlet passage 58.

  Therefore, as described above, the passage portion of the air leaking from the housing recess 40 moved by a predetermined distance is only a small gap between the opening peripheral portion 67 of the housing recess 40 and the inner surface 61 of the case body. The enclosed recess space communicated with the outlet passage 58. Therefore, the housing recess 40 moved by a predetermined distance becomes a space having a good sealing property, and the air injected into the housing recess 40 is effectively blown against the component 20 in a situation where the amount of leakage is small.

  An air supply pipe 65 connected to the air passage 64 is protruded to the outside from a through hole 66 provided in the back plate 47 of the case main body 24, and the through hole 66 is an air supply pipe 65 accompanying the forward and backward movement of the transfer member 38. The size is set to allow the forward and backward displacement.

  With such a configuration, the air supply pipe 65 moves in the through hole 66 following the forward / backward movement of the transfer member 38, and air injection into the housing recess 40 is ensured. Since the air supply pipe 65 is structured to be joined to the transfer member, the location of the air leakage is only a slight sliding gap between the opening peripheral portion 67 of the housing recess 40 and the case body inner surface 61. .

  As described above, the air injection from the auxiliary air injection port 63 causes the shaft-like component 20 to escape from the housing recess 40 into the supply passage tube 59, and subsequently, the conveyance air enters the supply passage tube 59 from the main air injection port 74. Be injected. Since the transfer member 38 can be moved to the next position at the same time as the conveying air is jetted, the transfer member 38 operates efficiently, and the delivery efficiency of the component delivery device is improved.

  The preliminary air injection port 63 opens toward the housing recess 40 (small recess 41) through an air passage 64 formed in the transfer member 38.

  Since the air for delivery is injected into the small recess 41 through the air passage 64 formed in the transfer member 38, the leaked air passage is located at the opening peripheral portion 67 of the housing recess 40 and the inner surface of the case body. Only a sliding gap in a small area between 61 and 61 is obtained. As described above, since there are only a few air leaks, noise associated with air circulation is significantly reduced. At the same time, since the amount of air leaking is small, the consumption of compressed air can be saved.

  By reducing the amount of leaked air, the air pressure behind the part can be set high, thereby rapidly increasing the delivery speed of the part 20, increasing the so-called initial speed, and delivering the part quickly. The conveyance can be realized and the transmission efficiency can be improved.

  And since the air injection port 63 is opened toward the inside of the small recess 41, the opening location and the opening direction are set according to the part shape, the part mass, etc., thereby reducing the amount of the injected air and sending out the parts. Can be performed at high speed, and it is possible to improve the delivery efficiency and reduce the consumption of compressed air. By selecting the opening location of the air injection port 63, it is also possible to cause the injection air to act on the component 20 as a dynamic pressure, thereby realizing faster component delivery.

  One entrance passage 28 is provided, and a plurality of receiving recesses 40 that match the entrance passage 28 are provided.

  When the component 20 that has entered the first receiving recess 40 from the one inlet passage 28 is moved to the outlet passage 58 side, the second receiving recess 40 is aligned with the inlet passage 28 to introduce the component. Made. The component 20 of the first housing recess 40 is sent to the supply passage pipe 59 by air injection from the preliminary air injection port 63 and the main air injection port 74. When the air injection from the preliminary air injection port 63 is completed with respect to the first component 20, the transfer member 38 is immediately moved to move the component 20 of the second accommodation recess 40 to another outlet passage 58. Similarly, preliminary air injection and main air injection are performed. By such a series of operations, the parts 20 introduced into the plurality of receiving recesses 40 are efficiently delivered.

  In the above-described embodiment, the component is introduced into the housing recess by the magnetic attraction force. However, the component passage member that guides the component into the case body is arranged in a substantially vertical direction, and the housing recess is caused by the gravity of the component. It can also be dropped inside. Therefore, in the description of the scope of claims, means for introducing the component into the housing recess is not described.

  As described above, according to the present invention, since it is a parts delivery device that can effectively attract parts by a magnet, effectively inject parts by air, and increase delivery efficiency, It can be used in a wide range of industrial fields such as welding processes and sheet metal welding processes for household appliances.
