Description

  The present invention relates to a component supply apparatus.

Conventional technology

  There is a component supply apparatus that includes a conveyance unit that arranges and conveys minute electronic components such as chip resistors and chip capacitors accommodated in the component storage unit, and a vibrator that vibrates the component storage unit and the conveyance path. When a component made of a material that is easily charged with static electricity is transported by this component feeder, static electricity is generated due to friction between the component and the transport path.

  When a large amount of static electricity is generated between the transfer surface of the transfer unit and the surface of the part that comes into contact with the transfer surface, the lighter parts or the parts and the bowl are attracted or repelled during transfer to align the parts. It interferes with transportation. In addition, if the component is supplied to the next process while being charged, dust in the air may adhere to the component and cause a defect in an electrical product in which the component is incorporated. As a countermeasure against static electricity in such a component supply device, in order to neutralize the charge charged to the component or the like by static electricity, it is possible to blow air mixed with static elimination ions toward the component conveyed from above the component supply device. Proposed.

  In addition, a technology has been proposed in which the component storage unit and the conveyance unit are configured by a single metal bowl, and the bowl is grounded to release static electricity charged in the bowl (see, for example, Patent Document 1).

JP 2001-39530 A

  However, when static electricity is generated between the bowl and the component, charges of opposite polarity are charged on the contact surfaces of the metal bowl B and the component W, as shown in FIG. When charges of opposite polarity face each other at a short distance such as between the metal bowl B and the part W, positive and negative charges are attracted to attract the metal bowl B and the part W, respectively. When the metal bowl B and the component W are attracted in this way, the ionized air ia from the outside does not reach between the metal bowl B and the component W, and the static electricity generated between the metal bowl B and the component W is It is not neutralized.

  Even in a state where the metal bowl B and the component W are attracted, the component W moves due to a collision between the components W, for example. Since the bowl B is made of metal and is a conductor, electric charges are induced on the surface of the bowl B by the electric charge of the charged component W. And as shown in FIG.14 (b), the electric charge induced | guided | derived to metal bowl B moves according to the electric charge charged to the component W. FIG. That is, since the state in which the metal bowl B and the part W are attracted is maintained, the ionized air ia from the outside does not reach the charged portion between the metal bowl B and the part W. Therefore, static electricity generated between the metal bowl B and the part W cannot be removed even if the part W moves. As described above, the conventional component supply apparatus cannot effectively remove static electricity generated between the component and the bowl.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to be able to effectively remove static electricity generated during transportation in a component supply device.

BEST MODE FOR CARRYING OUT THE INVENTION

  Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 6 are diagrams showing configuration examples of a vibratory bowl feeder 10 and a vibratory linear feeder 20 as component supply apparatuses according to the embodiment of the present invention. The vibratory bowl feeder 10 includes a bowl 11 and a vibratory bowl feeder vibrator 12. The bowl 11 is given a torsional vibration from a vibratory bowl feeder vibrator 12. Bowl 11 has as shown a cross-section of the bowl 11 in FIG. 5 which schematically shows a bottom 14 of a component housing, and a conveyor 15. The bottom portion 14 has a circular bottom surface 14a having a convex cross section at the center. The transport unit 15 is a side wall of the bowl 11, and has a spiral transport path 15 a extending from a part of the outer periphery of the bottom surface 14 a to the upper end of the outer periphery of the bowl 11. In addition, when it is not necessary to distinguish the bottom part 14 and the conveyance part 15 individually, it is only called the bowl 11. FIG. The vibratory bowl feeder vibrator 12 generates vibration by using, for example, an electromagnetic vibrator as a drive source. When the vibration of the vibratory bowl feeder vibrator 12 is transmitted to the bowl 11, a component (not shown) put into the bottom portion 14 of the bowl 11 moves on the conveyance path 15 a of the conveyance section 15, and the conveyance path From the terminal end 15a-end of 15a, it is fed into the vibration type linear feeder 20 through the arc-shaped crossing conveying section 16.

An ion generator 30 </ b> A as a static eliminator is provided in the vibrating bowl feeder 10. The ion generator 30 </ b> A discharges ionized air toward the bottom 14 of the bowl 11 and the transport unit 15. The ion generator 30 </ b> A removes static electricity generated by friction between the component and the bowl 11. A potential sensor 31 is provided in the vibrating bowl feeder 10. The potential sensor 31 measures the charging potential of the bottom 14 and the transport unit 15 in the bowl 11 in which the parts are accommodated and transported . Ionized air corresponding to the measurement result of the potential sensor 31 is released from the ion generator 30A.

  The vibration type linear feeder 20 includes a vibration type linear feeder vibrator 21 and a linear conveyance unit 22 attached to the upper part of the vibration type linear feeder vibrator 21. The vibration type linear feeder vibrator 21 has a fixed base 23. The transport unit 22 is coupled to the end of the cross transport unit 16. The vibration of the vibratory linear feeder vibrator 21 is transmitted to the transport unit 22, and components (not shown) move through the transport unit 22.

  An ion generator 30 </ b> B is provided above the vibration type linear feeder 20. As shown in FIG. 6, the ion generator 30 </ b> B blows ionized air ia toward the upper gap 22 a of the transport unit 22. The ion generator 30 </ b> B removes static electricity generated by friction between the component W and the transport surface 22 b of the transport unit 22. A potential sensor 32 for measuring the charging potential in the transport unit 22 is provided in the vibration type linear feeder 20. Ionized air corresponding to the measurement result of the potential sensor 32 is released from the ion generator 30B.

  The operations of the vibratory bowl feeder 10 and the vibratory linear feeder 20 are as follows. Parts are put into the bottom 14 of the bowl 11. When the bowl 11 is vibrated by the vibratory bowl feeder vibrator 12, the components are conveyed toward the outer periphery of the bottom surface 14 a of the bottom portion 14. Then, the components are transported on the transport path 15a of the transport unit 15 in a state of being aligned in a line. Subsequently, the component enters the conveyance unit 22 of the vibration type linear feeder 20 through the transfer unit 16 from the end 15a-end of the conveyance path 15a. The parts that have entered the transport unit 22 are transported by the transport unit 22 and delivered to the next process.

Details of the bowl 11 are as follows. The base part of the bottom part 14 of the bowl 11 and the conveyance part 15 are nonelectroconductive materials. The bowl 11 is made by cutting out a non-conductive material, for example. The base material is the basic structure portion 11b and the component storage portion or the transport portion 15 that is a portion that comes into contact with the component, that is, the component contact portion 11a . The basic structure portion 11b is a portion that retains the shape of the component storage portion or the conveyance portion, is vibrated by a vibrator, and transmits the vibration to the component. The non-conductive material is, for example, a synthetic resin material such as PET (polyethylene terephthalate), PP (polypropylene), epoxy resin, phenol resin, Teflon resin, and the like.

  The effects obtained by using the non-conductive material for the base of the bottom part 14 and the transport part 15 are as follows. When a part is thrown into the bottom part 14 of the bowl 11 and moves, or when the part 15 is transported, static electricity is generated between the part and the bowl 11 due to friction. When static electricity is generated, charges of opposite polarity are charged on the contact surfaces of the bowl 11 and the parts. In the example of FIG. 7A, a negative charge is charged on the bottom surface 14a of the bottom portion 14 or the contact surface on the bowl 11 side which is the transport path 15a of the transport portion 15, and a positive charge is charged on the contact surface on the component W side. To do. In this way, when charges having opposite polarities face each other at a short distance such as between the bowl 11 and the part W, the positive and negative charges attract each other, so that the bowl 11 and the part W attract each other. Therefore, since the ionized air ia from the outside does not reach between the bowl 11 and the part W, the electric charge charged between the bowl 11 and the part W is not neutralized.

Even when the bowl 11 and the component W are attracted in this way, the component W moves due to, for example, a collision between the components W. Since the base part of the bottom part 14 of the bowl 11 and the conveyance part 15 are nonconductive materials, the electric charge charged in the bowl 11 does not move. That is, as shown in FIG. 7B, even if the component W moves, the negative charge charged in the bowl 11 does not move but stops there. As a result, compared to the state shown in FIG. 7A, the bowl 11 and the component W are not attracted. Further, the part W and a part of the bowl 11 from which the part W is removed are in a state of being charged to the opposite polarity. Since it will be in such a state, parts W and a part of bowl 11 will be static-eliminated by spraying ionized air ia.

  In addition, when a non-conductive material, for example, a resin bowl 11 is used, the parts conveyance efficiency is improved for the following reason. The vibration frequency of the vibratory bowl feeder vibrator 12 depends on the weight of the bowl 11. When the weight of the bowl 11 is light, the vibration frequency is high. In the case of a high frequency, the parts are conveyed faster and in finer steps, and the conveyance efficiency is improved. Since the resin bowl 11 is lighter than the metal bowl, the parts conveyance efficiency can be improved.

  Furthermore, when a non-conductive material, for example, a resin bowl 11 is used, if the charge amount is the same when the bowl 11 is charged for the following reason, the resin bowl is compared with the potential of the metal bowl. 11 has a high potential. As a result, the resin bowl 11 has a greater force to attract ionized air than the metal bowl, and is easy to remove electricity. Further, when the charged charge amount is the same, the electric potential detected by the potential sensor 31 is larger because the resin bowl 11 has a higher potential than the metal bowl. Therefore, it is easy to perform control based on the measurement result of the potential sensor 31. Details will be described later.

  Here, FIG. 8 shows the reason why the potential of the charged resin bowl 11 is higher than the potential of the charged metal bowl B when the charged charge amount is the same. FIG. 8A corresponds to this embodiment. FIG. 8B corresponds to an example in which a metal bowl B is used. FIG. 8C corresponds to an example using a metal bowl B whose surface is coated with resin. First, the conditions are as follows to simplify the case. Non-conductive materials shall not be charged. The parts W are densely arranged on a 150 mm × 150 mm surface and arranged in a plate shape on one side. The electric charge charged to the component W exists uniformly only on the surface of the component W arranged in a plate shape on the bowl 11 side. That is, the component W is regarded as a single metal plate having a charge. Bowl 11 and bowl B are arranged below part W. The vibratory bowl feeder shaker 12 is disposed below the bowl 11 or the bowl B. That is, in the case of FIG. 8A, two metal plates, that is, parallel plates, of the component W and the vibratory bowl feeder vibrator 12, and in the case of FIGS. 8B and 8C, the component W and the bowl B. It is sandwiched between.

The relationship shown in Expression (1) is established for the charge Q, the charge potential V, and the capacitance C of the parallel plate. The charged charge Q in the formula (1) is obtained by the formula (2). In the formula (2), σ is the surface charge density of the charged charges of the parallel plate, and S is the area of the parallel plate. The capacitance C in the formula (1) is obtained by the formula (3). In equation (3), ε ₀ is the dielectric constant in vacuum, ε _r is the relative dielectric constant of the nonconductive material, and d is the distance between the two parallel plates. In the case of the present embodiment as shown in FIG. 8A, since the contact portion of the vibrating bowl feeder shaker 12 with the bowl 11 is a metal, the component W located in the bottom 14 of the bowl 11 and The metal distance d, that is, the distance between the two parallel flat plates, is the thickness of the bottom 14 of the bowl 11.

Therefore, the thickness of the bottom 14 of the bowl 11 is set to 5 cm, and the other elements in the expressions (2) and (3) are set to values shown in the following table. Since the charged charge Q is 2.25 × 10 ⁻⁷ [C] and the capacitance C is 7.92 × 10 ⁻¹² [F], the potential V of the bottom surface 14 a of the bowl 11 is 28409 [V]. It is.

  On the other hand, as shown in FIG. 8B, in the case of the metal bowl B, since the distance between the component W and the metal is a value close to zero, the capacitance C becomes a large value (formula (3)), The potential V on the bowl surface is a small value (formula (1)).

  For this reason, the potential of the charged resin bowl 11 is higher than the potential of the charged metal bowl.

A bowl with a resin coated metal surface is also conceivable. In this case, as shown in FIG. 8C, the distance d between the positive charge and the negative charge is the coating thickness. Since the coating thickness is several μm, the distance between the component W and the metal is shorter than that of the resin bowl 11, so that the capacitance C is large. Therefore, the potential of the bowl B when charged is smaller than the potential of the resin bowl 11. When the same charge amount Q = 2.25 × 10 ⁻⁷ [C] as described above is charged, for example, if the coating thickness is 5 μm, the capacitance C is 7.92 × 10 ⁻⁸ [F]. Then, the potential on the surface of the bowl B is 3 [V]. That is, it is much smaller than 28409 [V] which is the potential in the case of the resin bowl 11. As described above, the potential when the same electric charge is charged is highest in the case of the resin bowl 11 shown in FIG. 8A, and the metal bowl B having the resin coated on the surface shown in FIG. 8C. This is followed by the case of the metallic bowl B in which the resin is not coated on the surface shown in FIG.

In the above example, the base 14 of the bowl 11 and the base material of the transport unit 15 are non-conductive materials, but parts made of a conductive material such as metal may be added to the bottom 14 and the transport unit 15.

  An example of control based on the measurement result of the potential sensor 31 is as follows. Here, the case where the vibration intensity of the vibratory bowl feeder shaker 12 is controlled based on the measurement result by the potential sensor 31 will be described with reference to FIG.

  FIG. 9 schematically shows the vibratory bowl feeder 10 shown in FIG. In this example, a control device 51 is further provided.

The control device 51 controls the vibration intensity of the vibratory bowl feeder vibrator 12 according to the magnitude of the potential measured by the potential sensor 31. For example, when the potential of the bowl 11 in which the parts are accommodated and conveyed is less than 500V, the control mode of the control device 51 is the normal mode. In the normal mode, the control device 51 controls the vibratory bowl feeder vibrator 12 so that the bowl 11 vibrates at a vibration frequency and intensity that can more efficiently convey the parts based on the size and weight of the parts. To do. On the other hand, when the potential measured by the potential sensor 31 is equal to or higher than the threshold value of 500 V, the control mode is switched to the strong vibration mode. In the strong vibration mode, the control device 51 controls the vibratory bowl feeder shaker 12 so that the bowl 11 vibrates at a vibration frequency and intensity higher by a predetermined value than in the normal mode.

  In a situation where the potential is high, the positive and negative charges attracted by the component and the bowl 11 are high. Therefore, as described with reference to FIG. 7A, the force with which the bowl 11 and the component W are attracted is strong, and the component W is difficult to move. Therefore, the control device 51 switches the vibration of the vibratory bowl feeder shaker 12 from the normal mode to the strong vibration mode. By intensifying the vibration applied to the component W and moving the component W, the bowl 11 and the component W can be brought into the state shown in FIG. In the state shown in FIG. 7B, negative charges remain on the surface of the bowl 11 without moving, and positive charges remain on the surface of the component W facing the bowl 11. And the parts W and the bowl 11 are each neutralized by spraying ionized air.

  Next, the case where ionized air discharged from the ion generator 30A is controlled based on the measurement result by the potential sensor 31 will be described.

  Controlling ionized air is the following adjustment. It is to adjust the total amount of positive ions and negative ions, and to adjust the balance of positive ions and negative ions. Adjusting the balance between positive ions and negative ions includes releasing only positive ions or negative ions. A control mode in which positive ions and negative ions are released by the same amount is called a balanced mode, and a control mode in which positive ions and negative ions are released by different amounts is called an unbalanced mode.

  FIG. 10 schematically shows the vibratory bowl feeder 10 shown in FIG. In this example, a control device 61 is further provided. In this example, the control device 61 is incorporated in the ion generator 30A.

The control device 61 controls the ionized air emitted from the ion generator 30 </ b> A according to the magnitude of the potential measured by the potential sensor 31. For example, when the potential of the bowl 11 in which the parts are accommodated and conveyed is less than 500 V, the ion generator 30A operates in the balanced mode, and negative ions and positive ions are transferred from the ion generator 30A to the bowl 11. Released in a balanced manner. On the other hand, when the potential of the bowl 11 becomes 500 V or more, the ion generator 30A operates in the unbalanced mode, and a large amount of ions having a polarity opposite to the polarity of the charged component is released from the ion generator 30A. As a result, the parts are discharged efficiently.

  The ion generator 30A emits only ionized air having a polarity opposite to that of the charged component, or emits ionized air having a different balance between the amount of positive ions and negative ions. The amount of ionized air released from the ion generator 30A is variable. Thus, the control device 61 controls the balance between the amount of ionized air released from the ion generator 30A and the polarity. Thereby, optimal ionized air is emitted from the ion generator 30A. As a result, the parts are discharged efficiently. Note that the controller 61 may control only the amount of ionized air, may control only the balance of the polarity of ionized air, or may control both the amount of ionized air and the balance of polarity. Also good.

  In the above embodiment, the case where only the vibration intensity is controlled and the case where only the ionized air is controlled using the measured value of the potential sensor 31 are shown. In addition, vibration intensity control and ionized air control may be performed simultaneously. For example, the potential at which the vibration intensity control mode is switched is set to 500V, and the potential at which the control mode of ionized air is switched is set to 800V. Then, when the measurement result of the potential sensor 31 is 500 V or more and 800 V or less, the vibration intensity control mode is switched to the strong vibration mode, but the control mode of the ionized air remains in the balanced mode. In this state, the parts attracted by charging and the bowl 11 are separated. The static electricity generated between the component and the bowl 11 is removed by the ionized air.

  When the measurement result of the potential sensor 31 is 800 V or more, the control mode of the ionized air is switched to the unbalanced mode. The vibration intensity control mode is the strong vibration mode. In the strong vibration mode, the parts attracted by the charging and the bowl 11 are separated. At the same time, when the control mode of the ionized air is in the unbalanced mode, a large amount of ions having a polarity opposite to that of the charged component is discharged from the ion generator 30A, so that the component is efficiently discharged. . In this way, by controlling the vibration intensity and the ionized air at the same time, the parts are discharged more efficiently. The potential at which the vibration intensity control mode is switched and the potential at which the ionized air control mode is switched may be the same or different.

  The tact of the next process may be slower than the tact of the vibratory bowl feeder 10. In that case, the parts conveyed from the vibratory bowl feeder 10 cannot be processed in the next process and may stay in the conveyance unit 15 or the conveyance unit 22. In order to eliminate such stagnation, as shown in FIG. 11, an air supply pipe 33 is provided at a predetermined location of the bowl 11 and the parts to which the air supply pipe 33 has been conveyed are placed at the bottom as shown in FIG. 14 can be blown away. Since the parts are blown off by the air supply pipe 33, the parts are not transported to the next process.

  Although the case where the bottom 14 of the bowl 11 of the vibration type bowl feeder 10 and the base material of the conveyance unit 15 are made of a non-conductive material is mentioned, the base material of the conveyance unit 22 of the vibration type linear feeder 20 is made of a non-conductive material. You can also. Thereby, the static electricity can be effectively removed as in the case of the vibrating bowl feeder 10.

  The ion generator 30 </ b> A in FIG. 1 is provided above the bowl 11. The ion generator 30 </ b> A neutralizes the parts conveyed in the bowl 11. As shown in FIG. 11, an appropriate number of small holes 17 may be provided near the periphery of the bottom surface 14 a of the bowl 11, and ionized air may be blown upward from the lower side of the bowl 11 to the small holes 17.

  In the example of FIGS. 9 and 10, the vibration intensity of the vibratory bowl feeder shaker 12 and the ionized air from the ion generator 30 </ b> A are automatically set according to the potential value of the bowl 11 measured by the potential sensor 31. Controlled. As another example, as shown in FIG. 12, using a controller 50 having a mode switching unit that can manually switch between a normal mode, a strong vibration mode, a balanced mode, and an unbalanced mode. Vibration intensity and ionized air may be controlled. In the normal mode, the vibratory bowl feeder shaker 12 vibrates at a vibration frequency and intensity that can more efficiently convey the parts to be conveyed. In the balanced mode, negative ions and positive ions are released in a balanced manner from the ion generator 30A. In the strong vibration mode, the vibratory bowl feeder shaker 12 vibrates at a vibration frequency and intensity higher by a predetermined value than in the normal mode. In the unbalanced mode, a large amount of ions having a polarity opposite to that of the charged component is released from the ion generator 30A.

  The mode switching unit includes a push button switch 41 for designating the normal mode, a push button switch 42 for designating the strong vibration mode, a button switch 43 for designating the balanced mode, and a button switch for designating the unbalanced mode. 44 is provided.

FIG. 13 is a diagram illustrating another example of the component supply apparatus. The rectilinear component supply device 70 includes a rectilinear component accommodating portion 71 as two component accommodating portions and a rectilinear conveyer 72 . The rectilinear conveyance unit 72 is provided between the two rectilinear component housing units 71. The rectilinear conveyance section 72 has one end connected to one end 71b of each rectilinear component housing 71 and extends in parallel to the other side (right side in FIG. 13). The linear component housing 71 and the linear conveyance unit 72 are given vibrations from a vibrator (not shown) that supports them from below.

Parts are thrown into the upper surface of the other end 71a of each rectilinear component housing 71. The thrown-in components are conveyed to one end portion 71b of the linear component housing portion 71 by vibration applied from the vibrator, and are gradually aligned in a row therebetween. The aligned parts are transferred one by one from the one end 71b of the rectilinear component receiving portion 71 to the one end 72a of each rectilinear conveying portion 72, and the other end of the rectilinear conveying portion 72 (FIG. 13). Is conveyed to the right end). The parts conveyed to the other end of the straight type conveyance unit 72 are delivered to the next process.

In the rectilinear component supply device 70, the base material of the rectilinear component housing portion 71 and the rectilinear transport portion 72 is a non-conductive material.

By using the non-conductive material for the bases of the linear component receiving unit 71 and the linear conveying unit 72, in the linear component supplying apparatus 70, the components and the linear component accommodating unit 71 or the linear conveying unit are used. Even if static electricity is generated by contact friction with 72 or contact friction between parts, the static electricity is eliminated by ionized air. Therefore, the components can be smoothly conveyed without being attracted to the linear component housing part 71 or the linear conveyance unit 72 by electrostatic force.

In the rectilinear component supply apparatus 70, the charged electric potentials of the rectilinear component accommodating portion 71 in which the components are accommodated and the rectilinear conveying portion 72 in which the components are conveyed are measured by a potential sensor (not shown), and the charging potential is added according to the measured value. It is also possible to control the vibration intensity of the shaker or to control ionized air from an ion generator (not shown). Moreover, the controller 50 which has the mode switching part which can switch each of normal mode, strong vibration mode, balanced mode, and unbalanced mode manually which was illustrated in FIG. 12 can also be provided.
