Description

  The present invention relates to a vibration type component conveying apparatus that vibrates a component conveying member having a linear conveying path and conveys components on the conveying path.

  As a device that aligns small components such as electronic chip components while conveying them by vibration (aligns the posture of the components) and supplies them to the next process, it has a chute (component conveying member) with a linear conveying path formed. In addition, a vibratory parts conveying apparatus having a bowl with a spiral conveying path on the upstream side of a vibratory linear feeder that is easy to adjust the parts supply speed and connected with a vibratory bowl feeder that can store many parts. Often used.

  In the vibratory parts conveying apparatus as described above, the bowl of the bowl feeder is vibrated to convey the parts thrown into the bottom of the bowl through a spiral conveying path, and from the outlet to the inlet of the conveying path of the straight feeder chute The parts are delivered to the machine and the chute of the linear feeder is vibrated, so that the parts on the chute conveyance path are conveyed linearly and supplied to the next process. However, since the vibration direction, vibration frequency, and amplitude are generally different between the bowl feeder and the linear feeder, it is necessary to provide a gap between the conveyance path outlet of the bowl feeder and the conveyance path inlet of the linear feeder at the parts transfer section between both feeders. There is a tendency to clog or catch parts in this gap. Therefore, normally, the parts transfer section overlaps the bowl transfer path with the bowl transfer path higher than the chute transfer path so that the parts can be easily transferred from the bowl feeder to the straight feeder (for example, patents). Reference 1).

  However, when a drop is provided between the conveying paths of the parts delivery unit in this way, even if the parts are aligned by the bowl feeder, the posture changes due to the impact when the parts move to the linear feeder, There may be overlap. In a linear feeder, the cross section of the transport path is often formed in a shape that restricts the behavior of the parts, such as a V-groove and a U-groove, so that the overlapped parts are easily transported as they are.

  On the other hand, in Patent Document 2, the cross section of the conveyance path of the linear feeder is formed in an R-groove shape, thereby increasing the degree of freedom of the behavior of the component, and the component that has been conveyed in a state of being overlapped or arranged in two rows. It has been proposed to make it easier to align the lines in a row. However, even if the conveyance path has an R-groove shape as described above, when the component conveyance amount increases, a component in a defective posture or a component in an overlapped state is conveyed.

  For this reason, in general, a sorting portion is provided on the chute of the linear feeder to reliably align the components in the middle of the conveyance path. And as the alignment means, the compressed air is blown to the parts in the defective posture, and the parts in the defective posture are excluded from the conveyance path (for example, refer to Patent Document 3), or the wiper protruding onto the conveyance path of the sorting unit In many cases, a part that removes only the upper part of the parts conveyed in an overlapping state from the conveyance path is employed.

JP 2000-118682 A JP 2007-308216 A Japanese Patent Laying-Open No. 2007-284156 (FIG. 9)

  However, even in the vibration type component conveying apparatus provided with the sorting unit having the alignment means as described above, the sorting unit is sufficiently aligned depending on the conveyance conditions, as described below with reference to FIGS. 10 to 12. There are things that cannot be done.

  10 (a) to 10 (c) show a vibration-type component conveying apparatus for aligning and conveying a substantially rectangular parallelepiped-shaped component P (see FIG. 2). An example of the sorting unit 53 provided for the purpose is shown. In the sorting section 53, the transport path 52 is formed in a V-shaped cross section, and a block-shaped wiper 54 that protrudes onto the transport path 52 is provided on one side (in the width direction) of the transport path 52.

  The wiper 54 is formed such that its inlet portion (upstream end portion in the transport direction) 54a is inclined toward the downstream side in the transport direction toward the other side of the transport path 52. The wiper 54 is opposed to the conveyance path 52 by a downwardly inclined surface 54b, and a ventilation plate 55 is fixed to the upwardly inclined surface 54c formed between the downwardly inclined surface 54b and the upper surface by screws 56. Yes. Further, air passages 57 and 58 communicating with the wiper 54 and the air passage plate 55 are provided, and the air passage 58 of the air passage plate 55 opens above the transport passage 52 so that the air flow of the wiper 54 from the compressed air source (not shown) can be performed. The compressed air supplied to the path 57 is jetted obliquely downward toward the outside slightly of the other side edge of the transport path 52.

  In this vibration type component conveying apparatus, as shown in FIGS. 11A to 11C, the sorting unit 53 has an attitude in which the longitudinal direction is directed to the conveying direction (hereinafter, this attitude is referred to as “good attitude”). The parts P that have been conveyed enter the inside of the wiper 54 without coming into contact with the wiper 54 in a stable state where the entire part P is within the width of the conveyance path 52. Then, as shown in FIG. 12A, even if the well-positioned part P entering the inside of the wiper 54 passes through the opening of the ventilation path 58 of the ventilation plate 55, that is, below the air outlet 59, the air Since the compressed air ejected from the ejection port 59 hardly hits, it is conveyed downstream without changing the posture.

  Here, the gap between the downwardly inclined surface 54b of the wiper 54 and the side wall on the other side (outside in the width direction) of the conveyance path 52 is set to a dimension that allows only one good-positioned component P to pass therethrough. For this reason, although illustration is omitted, when the component P in a good posture is conveyed in a state of being overlapped along the side wall on one side of the conveyance path 52, only the upper component P of the component P is the entrance of the wiper 54. After colliding with the part 54 a, it is guided by the inlet part 54 a and falls to the other side of the conveyance path 52.

  On the other hand, as shown in FIG. 11 (c), the part P that has been transported to the sorting unit 53 in a defective posture (the orientation in which the longitudinal direction is directed to the width direction of the transport path) has a transport path formed in a V-shaped cross section. It leans on one of the side walls of 52 and causes either one end in the longitudinal direction to protrude to the side of the conveyance path 52. Of these, the part P that leans against the side wall on one side of the transport path 52 and protrudes at one end in the longitudinal direction to the one side of the transport path 52 has its protruding part at the inlet 54a of the wiper 54. , It falls to the other side of the conveyance path 52, as is the case with the upper side of the above-mentioned superposed part P having a good posture.

  On the other hand, among the parts P in the defective posture, the parts P leaning against the side wall on the other side of the transport path 52 and protruding one end portion in the longitudinal direction to the other side of the transport path 52 are Since the protruding portion does not contact the wiper 54, as shown in FIGS. 11A and 11B, the protruding portion enters the inside of the wiper 54 together with the component P in a good posture.

  As shown in FIG. 12 (b), the defective part P entering the wiper 54 usually protrudes from the other side of the conveyance path 52 when it reaches the lower side of the air outlet 59 of the ventilation plate 55. Compressed air is sprayed onto the carrier path 52 so that it rotates from the contact position with the other side edge of the transport path 52 as a fulcrum and falls from the transport path 52.

  However, when the component P in a poor posture is conveyed in the state of being sandwiched between the components P in a good posture from the front and rear (upstream side and downstream side in the conveyance direction), as shown in FIG. 54, even if a part P in a bad posture that enters inside 54 receives compressed air ejected from the air outlet 59 of the ventilation plate 55 at one end and rotates to some extent, the other end tilts downward on the wiper 54. When it comes into contact with the surface 54b, the rotation is restricted by friction with the wiper 54 and the front and rear parts P, and may not be excluded from the transport path 52. If the defective part P is not removed by the sorting unit 53 and is transported downstream in this way, troubles such as part clogging are caused and the parts supply capability of the vibration type part transport device is reduced. .

  Here, if the amount of compressed air ejected from the air jet port 59 of the ventilation plate 55 is increased, even if the component P in the poor posture is sandwiched between the components P in the good posture as described above, the component P in the defective posture is obtained. However, when the compressed air ejected from the air outlet 59 expands, a swirl is generated and the component P, which has been in a good posture, becomes unstable due to the swirl. It will fall from the conveyance path 52, and there exists a possibility that component supply capability may fall large. Therefore, the amount of compressed air cannot be increased unnecessarily in order to eliminate defective posture parts P.

  Accordingly, the present invention is to make it possible to reliably eliminate defective parts and to obtain a stable component supply capability in a vibration-type component transport apparatus that targets components that are elongated in one direction for alignment supply. Is an issue.

  In order to solve the above problems, the present invention has a conveyance path that linearly conveys a part that extends long in one direction, and the width dimension of the conveyance path is in the middle of the conveyance path from the longitudinal dimension of the part. Provided with a sorting section that is formed in a short length, and a wiper that projects upward from one side of the transport path to the sorting section. In the sorting section, either one end in the longitudinal direction is directed to one side of the transport path. The protruding part is dropped to the other side of the conveying path when the protruding part collides with the entrance of the wiper, and either one end in the longitudinal direction protrudes to the other side of the conveying path. In the vibratory component conveying device, the protruding portion of the wiper is configured to drop to the other side of the conveying path when the protruding portion receives the compressed air ejected from the air ejection port in the wiper. On the opposite surface in the vertical direction, A part having a posture in which a guide groove gradually approaching the other side of the conveyance path toward the downstream side of the conveyance path is provided, and any one end in the longitudinal direction protrudes to the other side of the conveyance path in the wiper. However, by receiving the compressed air and rotating with the contact position with the other side edge of the conveyance path as a fulcrum, the other end is conveyed in a state of being fitted in the guide groove of the wiper, It was made to fall to the other side of the conveyance path at the downstream part of the wiper. According to this configuration, the part that has entered the inside of the wiper with a defective posture in which either one end in the longitudinal direction protrudes to the other side of the conveyance path can be reliably removed at the downstream side portion of the wiper. Parts clogging and the like are less likely to occur downstream from the sorting section, and the parts can be stably supplied to the next process.

  In the above configuration, when the conveyance direction dimension of the air ejection port is set to be three times or more the longitudinal dimension of the component, the component in the defective posture is fitted in the guide groove of the wiper at the other end. In this case, the distance traveled through the wiper becomes longer, so that parts with a defective posture can be more reliably eliminated.

  In addition, if the guide groove of the wiper is formed with an inclination of 10 to 20 degrees with respect to the transport direction, the part with the other end fitted in the guide groove of the wiper has a higher transport speed. Since it can be transported without being lowered and removed from the transport path, the stability of the component supply capability can be improved.

  In addition, by providing a plurality of rows of the guide grooves of the wiper in parallel with each other, the probability that the other end of the defective posture part fits into the guide groove of the wiper is increased, and the defective posture part is more reliably eliminated. It can also be done.

  Here, if the pitch of the guide groove of the wiper is set to ¼ or less of the width of the part, the part in a good posture (position in which the longitudinal direction is directed to the transport direction) contacts the surface of the wiper facing the transport path. Even in such a case, it is difficult to enter the guide groove, so that the components in good posture can be smoothly conveyed to the downstream side.

  Further, if the cross-sectional shape of the periphery of the groove edge of the guide groove of the wiper is formed in a square shape with the groove edge of the guide groove as a vertex, the other end portion of the defective posture part fitted in the guide groove is Since it becomes difficult to escape due to being caught, it is possible to more smoothly convey and remove parts in a defective posture within the wiper.

  Further, in the case where the transport path is formed in a V-shaped cross section in the sorting section, the inclination direction dimension of the other side wall of the transport path having the V-shaped cross section is set to the other side wall of the transport path. By setting a dimension smaller than the distance from the center of gravity of the component in a posture in which any one end in the longitudinal direction protrudes to the other side of the transport path in a leaning state, to the side wall on one side of the transport path, When the component in the defective posture receives the compressed air, it becomes easy to rotate using the contact position with the other side edge of the conveyance path as a fulcrum, and the component in the defective posture can be removed more smoothly.

  As described above, the vibration type component conveying apparatus of the present invention gradually moves toward the downstream side of the conveying path on the surface facing the conveying path of the wiper projecting upward from one side of the conveying path by the sorting unit. By providing a guide groove approaching the other side, a part with a defective posture with one end protruding to the other side of the conveyance path receives compressed air when it enters the wiper and rotates. It is transported with the end part fitted in the guide groove of the wiper, and is surely excluded from the transport path at the downstream part of the wiper. Is less likely to occur, and parts can be stably supplied to the next process.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 9. The vibratory component conveying apparatus of the embodiment shown in FIG. 1 performs the alignment supply of a substantially rectangular parallelepiped component P that extends long in one direction as shown in FIG. 2, and a vibratory bowl feeder 11 and a downstream side thereof. A vibration type linear feeder 21 is provided. Then, by vibrating the bowl 12 of the bowl feeder 11, the component P put into the bottom of the bowl 12 is conveyed by the spiral conveying path 13, and the chute (component conveying member) 1 of the linear feeder 21 is discharged from the outlet. By delivering the part P to the entrance of the straight conveyance path 2 and vibrating the chute 1 of the linear feeder 21, the part P on the conveyance path 2 of the chute 1 is conveyed linearly and supplied to the next process. ing.

  Since the bowl feeder 11 and the linear feeder 21 have different vibration directions, vibration frequencies, and amplitudes, the conveying path 13 of the bowl 12 is set higher than the conveying path 2 of the chute 1 at the parts transfer portion between the feeders 11 and 21. Both conveying paths 13 and 2 are overlapped so that the parts can easily transfer from the bowl feeder 11 to the linear feeder 21.

  The linear feeder 21 is provided with a sorting unit 3 in the middle of the conveying path 2 of the chute 1, and the sorting unit 3 eliminates the defective posture parts P, and the downstream portion of the sorting unit 3 has a good posture. Only the part P is conveyed to the exit in the same posture. The part P removed by the sorting unit 3 is returned to the bottom of the bowl 12 of the bowl feeder 11.

  The sorting portion 3 of the chute 1 of the linear feeder 21 has the same basic configuration as the conventional one, and the conveyance path 2 has a V-shaped cross section as shown in FIGS. 3 (a) and 3 (b). A block-shaped wiper 4 is provided on one side (inward in the width direction) of the conveyance path 2 so as to project onto the conveyance path 2. In the sorting unit 3, the width dimension of the conveyance path 2 is formed to be shorter than the longitudinal dimension of the component P.

  The wiper 4 is formed such that an inlet portion (upstream end portion in the transport direction) 4a is inclined toward the downstream side in the transport direction toward the other side of the transport path 2. The wiper 4 is opposed to the conveyance path 2 by a downward inclined surface 4b, and a gap between the downward inclined surface 4b and the side wall on the other side (width direction outer side) of the conveyance path 2 is in a good posture (longitudinal direction). Is set to a dimension that allows only one component P to pass therethrough.

  Further, an upwardly inclined surface 4c is formed between the downwardly inclined surface 4b and the upper surface of the wiper 4, and the ventilation plate 5 is fixed to the upwardly inclined surface 4c with screws 6. Further, air passages 7 and 8 communicating with the wiper 4 and the air passage plate 5 are provided, and the air passage 8 of the air passage plate 5 opens above the transport passage 2 so that the air flow of the wiper 4 from the compressed air source (not shown) can be performed. The compressed air supplied to the path 7 is jetted obliquely downward toward the outside slightly of the other side edge of the transport path 2.

  Here, the opening of the ventilation path 8 of the ventilation plate 5, that is, the air outlet 9 is considerably longer than the conventional one in the conveyance direction and is formed to be three times or more the longitudinal dimension of the component P.

  Further, the downwardly inclined surface 4b of the wiper 4 (the surface facing the conveyance path 2 in the vertical direction) gradually moves toward the downstream side of the conveyance path 2 (at an inclination of 10 to 20 degrees with respect to the conveyance direction). A plurality of guide grooves 10 approaching the other side of 2 are provided in parallel with each other, and the pitch is ¼ or less of the width dimension of the component P. And the cross-sectional shape of the groove edge peripheral part of each of these guide grooves 10 is formed in the corner | angular shape which makes the groove edge of the guide groove 10 a vertex, Thereby, the cross-sectional shape of the downward inclined surface 4b of the wiper 4 is the whole. It has a saw blade shape.

  Next, based on FIG. 4 thru | or FIG. 7, the behavior of the components P in the selection part 3 of the chute | shoot 1 is demonstrated. The sorting part 3 of the chute 1 not only carries the component P in a good posture alone, but also overlaps the component P in a defective posture (the orientation in which the longitudinal direction is in the conveyance path width direction) or in a good posture. The part P in the state is also conveyed. This is because, as described above, the conveyance path 2 of the chute 1 is lower than the conveyance path of the bowl, and even when the part P aligned by the bowl feeder 11 is transferred to the linear feeder 21, the posture is changed by the impact. This is because they overlap with other parts P. The parts P conveyed to the sorting unit 3 behave differently as follows depending on their postures.

  First, as shown in FIGS. 4 (a) and 4 (b), the part P that has been transported alone to the sorting unit 3 in a good posture is in a stable state in which the entire part is within the width of the transport path 2. Enter the inside of the wiper 4 without contacting the 4. And even if the component P in a good posture that has entered the inside of the wiper 4 passes below the air outlet 9 of the ventilation plate 5, the compressed air ejected from the air outlet 9 hardly hits it. It is conveyed downstream without being changed and supplied to the next process.

  On the other hand, although illustration is omitted, when the component P in a good posture has been conveyed in a state of being overlapped along the side wall on one side of the conveyance path 2, only the upper component P is the inlet portion of the wiper 4. After colliding with 4a, it is guided by the inlet 4a and falls to the other side of the conveyance path 2.

  Further, the part P that has been transported to the sorting unit 3 in a defective posture leans against one of the side walls of the transport path 2 so that either one end in the longitudinal direction protrudes to the side of the transport path 2. Become. Of these, the part P that leans against the side wall on one side of the conveyance path 2 and protrudes at one end in the longitudinal direction to one side of the conveyance path 2 has its protruding portion as the inlet portion 4 a of the wiper 4. , It falls to the other side of the conveyance path 2 in the same manner as the above-mentioned part P on the upper side of the superposed good posture.

  Further, among the parts P in the poor posture, the part P leaning on the side wall on the other side of the conveyance path 2 and protruding one end in the longitudinal direction to the other side of the conveyance path 2 is shown in FIG. ) And (b), since the wiper 4 is not touched, the wiper 4 enters the wiper 4 together with the component P in a good posture. And when it reaches the lower part of the air jet outlet 9 of the ventilation plate 5, by compressing air to the part which protrudes from the conveyance path 2 other side, as shown to Fig.5 (a), (b), It rotates until the other end abuts on the downward inclined surface 4b of the wiper 4 with the contact position with the other side edge of the transport path 2 as a fulcrum. At this time or immediately after that, the other end of the component P is fitted into one of the guide grooves 10 formed in the downward inclined surface 4 b of the wiper 4.

  Here, since the guide groove 10 of the wiper 4 is formed so as to gradually approach the other side of the transport path 2 toward the downstream side of the transport path 2 as described above, the other end portion of the guide groove 10 As shown in FIGS. 6 (a) and 6 (b), the part P fitted into one is transported to the downstream side of the transport path 2 even if it is sandwiched between the parts P in a good posture from the front and rear. As the other end approaches the other side of the conveyance path 2, the rotation angle with the contact position with the other side edge of the conveyance path 2 as a fulcrum increases, and FIGS. 7 (a) and 7 (b). As shown in FIG. 4, the sheet is dropped to the other side of the conveyance path 2 at the downstream portion of the wiper 4.

  As described above, the vibration type component conveying apparatus is configured such that the upper part of the components P in the good posture conveyed in an overlapping state in the sorting unit 3 provided in the middle of the conveying path 2 of the chute 1 of the linear feeder 21. The part P and the part P in which one end part in the longitudinal direction protrudes to one side of the transport path 2 are removed by the inlet part 4a of the wiper 4, and transports either one end part in the longitudinal direction. The part P that protrudes to the other side of the path 2 rotates in response to the compressed air ejected from the air outlet 9 of the ventilation plate 5 in the wiper 4, and the other end fits into the guide groove 10 of the wiper 4. Since it is transported in a clogged state, it has fallen to the other side of the transport path 2 at the downstream portion of the wiper 4, so that there is a component clogging etc. downstream of the sorting section 3 of the transport path 2. Providing parts P to the next process in a stable manner, unlikely to occur It can be.

  And the following points also contribute to improving the stability of the component supply capability by more reliably removing the component P in a defective posture. First, the air ejection port 9 of the ventilation plate 5 is formed so that the conveyance direction dimension is three times or more the longitudinal dimension of the component P, and the component P in a poor posture fits into the guide groove 10 of the wiper 4 at the other end. The distance that the wiper 4 is transported in the retracted state can be long.

  Further, the guide groove 10 of the wiper 4 is formed with an inclination of 10 to 20 degrees with respect to the conveying direction, and the part P having a bad posture in which the other end is fitted into the guide groove 10 is increased in conveying speed. It can be transported without being lowered and removed from the transport path 2.

  A plurality of rows of guide grooves 10 are provided in parallel with each other, and the pitch thereof is ¼ or less of the width dimension of the component P, so that the other end of the component P in the defective posture is securely fitted into the guide groove 10. The part P in a good posture is stuck and eliminated, and even if it comes into contact with the downwardly inclined surface 4b of the wiper 4, it does not easily enter the guide groove 10 and can be smoothly conveyed downstream.

  Further, the cross-sectional shape of the periphery of the groove edge of the guide groove 10 is formed in a square shape with the groove edge of the guide groove 10 as a vertex, and the other end portion of the component P in a poor posture fitted in the guide groove 10 is Since it is difficult to escape due to being caught, it is possible to smoothly convey and remove the parts P in a defective posture within the wiper 4.

  In addition, by appropriately setting the size of the conveyance path 2 of the chute 1 according to the parts P to be aligned and supplied as described below, the parts P in the defective posture can be more smoothly eliminated. it can.

  That is, for example, as shown in FIG. 8, the dimension of one side of the square cross section at both ends in the longitudinal direction of the parts P to be aligned and supplied is W, the dimension in the longitudinal direction is 2W, and the center of gravity is the center position of the shape. Suppose that In this case, as shown in FIG. 9, the inclination direction dimension X of the other side wall of the conveyance path 2 is set to a defective posture (one end portion in the longitudinal direction in a state leaning on the other side wall of the conveyance path 2). Is set to a dimension smaller than the distance Y (= W) from the center of gravity G of the part P of the part P of the part P of the conveying path 2 to the other side of the conveying path 2, thereby causing the defective attitude When the part P receives compressed air, it becomes easy to rotate with the position of contact with the other side edge of the conveyance path 2 as a fulcrum, so that the part P in a defective posture can be removed more smoothly. At the same time, in order to stably carry the component P in a good posture, it is preferable to set the inclination direction dimension X of the side wall on the other side of the carrying path 2 to about 2/3 W.

  In addition, the present invention is not limited to the vibratory component conveying device in which the vibratory linear advance feeder is connected to the downstream side of the vibratory bowl feeder as in the above-described embodiment, and a linearly extending part extending in one direction is conveyed. The present invention can be widely applied to a vibration type component conveying apparatus including a component conveying member that conveys along a path.
