The article 75 is conveyed in the second conveyance path 15 in the opposite direction to the first conveyance path 4 by the reciprocating linear movement of the second conveyance unit 13.

 In this case, vibration different from that of the first transport unit 2 is given to the second transport unit 15 by the cooperation of the guide mechanism 17 and the limiting mechanism 20. For example, as shown in FIGS. 7A and 7B, when the first conveyance path 4 is displaced forward in the horizontal direction (article conveyance direction) and upward in the vertical direction, the second conveyance path 15 is horizontal. Displaces forward in the direction and downward in the vertical direction. When the first transport path 4 is displaced rearward in the horizontal direction and downward in the vertical direction, the second transport path 15 is displaced rearward in the horizontal direction and upward in the vertical direction. The articles 75 in the second transport path 15 are transported in the direction opposite to the first transport path 4 by the reciprocating linear motion of the second transport path 15 in the horizontal direction (transport direction) and the vertical direction. .

  As shown in FIGS. 1 to 6 and FIGS. 8 to 10, the vibration applying mechanism 30 applies vibration for conveying the article 75 to the first conveying unit 2, and is a base (not shown). A housing 31 fixed to the upper portion of the housing 31, an input shaft 40 rotatably provided in the housing 31, and a first cam mechanism 41 provided in the housing 31 for converting the rotational motion of the input shaft 40 into a reciprocating linear motion. A second cam mechanism 50 that converts the rotational motion of the input shaft 40 into a reciprocating linear motion, an output unit 60 that is driven by the first cam mechanism 41 and the second cam mechanism 50, and a drive that rotationally drives the input shaft 40. And a source 65.

  Here, the first cam mechanism 41 has a function of converting the rotational motion of the input shaft 40 into a reciprocating linear motion in a first direction having at least the conveyance direction of the article 75, and the second cam mechanism 50 has the input shaft By having the function of converting the rotational movement of 40 into the reciprocating linear movement in the second direction having the normal direction component of the conveying surface 5 that conveys at least the article 75, and by synthesizing the reciprocating linear movement in these two directions The obtained vibration is given to the first transport unit 2 via the output unit 60. Since this vibration has a conveying direction component related to the inertial force term and a normal direction component related to the frictional force term necessary for effectively controlling the relative slip of the article 75 with respect to the conveying surface 5, the conveying surface 5 can be efficiently conveyed in the conveying direction.

  In the following description, the first direction is the horizontal direction (transport direction), and the second direction is the normal direction of the transport surface (vertical direction). However, the first direction is not necessarily limited to this direction. The reciprocating linear motion in one direction may include a component in a direction other than the transport direction, and the reciprocating linear motion in the second direction may include a component other than the normal direction. Alternatively, the transport direction in the first direction may be inclined by a predetermined angle from the horizontal, and the second direction may be the normal direction of the transport surface inclined.

  As shown in FIG. 8, the housing 31 has a box shape having a void inside, and a rectangular opening 32 penetrating the inside and outside of the void is provided on the upper surface side. In the empty space of the housing 31, a single input shaft 40 is horizontally and rotatably provided in the central portion, and the output portion 60 is disposed in the horizontal direction (article 75) at the inner portion of the opening 32 above the input shaft 40. The first cam mechanism 41 and the second cam mechanism 50 are provided between the output unit 60 and the input shaft 40.

  As shown in FIG. 8, the input shaft 40 is rotatably supported between a pair of front and rear walls 33, 34 of the housing 31 via a pair of bearings 35, 35, and one end portion penetrates the front wall. A drive shaft (not shown) of a drive source 65 provided on the outer surface side of the front wall of the housing 31 is connected to the protruding portion of the housing 31 via a shaft coupling (not shown). The input shaft 40 is configured to be rotationally driven through the drive shaft by driving the drive source 65.

  As shown in FIGS. 8 and 10, the output unit 60 is horizontally provided in a portion inside the opening 32 of the housing 31 and is a rectangular plate-shaped output unit main body 61 slightly smaller than the opening 32 of the housing 31. And a pair of rectangular plate-like lift members 62, 62 provided integrally at both ends in the longitudinal direction on the lower surface side of the output unit main body 61, and the first transport unit 2 is provided on the upper surface side of the output unit main body 61. It is fixed horizontally.

  A seal member 69 made of an elastic material such as rubber is interposed between the peripheral surface of the output portion main body 61 and the inner peripheral surface of the opening 32 of the housing 31. The lubricating oil 70 filled in the empty space is prevented from leaking out of the housing 31. The seal member 69 elastically deforms following the reciprocating linear movement of the output part main body 61 in the horizontal and vertical directions, thereby allowing the output part main body 61 to reciprocate linearly in the horizontal and vertical directions. .

  The pair of lift members 62, 62 are integrally provided on the lower surface side of the output unit body 61 so as to be orthogonal to the upper surface (or lower surface) of the output unit body 61, and both side surfaces 63, 63 ( The end surface along the conveyance direction of the article 75 is formed as a flat surface facing the vertical direction.

  As shown in FIGS. 8 to 10, the portion on the inner surface side of the housing 31 facing each side surface 63 of each lift member 62 is parallel to each side surface 63 of each lift member 62 and to each side surface 63. Plate-shaped guide members 36 each having a slidable flat guide surface 37 are integrally provided. Both the guide members 36 and 36 allow the lift members 62 and 62 to move in one horizontal direction (conveyance direction) and the vertical direction, and to move in the other horizontal direction (direction perpendicular to the conveyance direction). Be regulated. As a result, the output body 61 integrated with both lift members 62, 62 is allowed to move in one horizontal direction (conveying direction) and in the vertical direction, and in the other horizontal direction (direction perpendicular to the conveying direction). Movement is restricted.

  A predetermined gap (not shown) is provided between each side surface 63 of each lift member 62 and the guide surface 37 of each guide member 36 that slides with each side surface 63, and the viscous fluid 70 is placed in the gap. By interposing, it may function as a so-called oil film damper.

  That is, a predetermined gap is provided between each side surface 63 of each lift member 62 and the guide 37 face of each guide member 36, and the viscous fluid 70 is interposed in this gap, and in this state, each lift member 62 and each guide By moving the member 36 relative to each other, a velocity gradient is generated in the viscous fluid 70, and a force opposite to the relative movement acts between the lift member 62 and the guide member 36. This acts as a braking force that attenuates.

  In this case, since the housing 31 is filled with the lubricating oil 70 which is a viscous fluid as described above, the housing 31 has a gap between the side surfaces 63 of the lift members 62 and the guide surfaces 37 of the guide members 36. In this case, the lubricating oil 70 is always present, so that it can function as an oil film damper.

  Since the oil film damper can attenuate harmful vibrations of the transport unit 2 itself caused by the bending deformation of the transport unit 2, the first cam mechanism 41 and the second cam mechanism 50 operate as designed. Can be applied to the first transport unit 2.

  In addition, it is preferable to set the clearance gap between the lift member 62 and the guide member 36 in the range of 0.005 mm-0.05 mm. By setting the clearance within this range, it is possible to reliably prevent physical contact between the guide surface 37 of the guide member 36 and the side surface 63 of the lift member 62 and to reduce the backlash of the first transport unit 2. Can be suppressed.

  Further, a groove may be formed on at least one of the guide surface 37 of the guide member 36 and the side surface 63 of the lift member 62. By forming such a groove, the holding force of the viscous fluid 70 in the gap can be increased, so that the function as an oil film damper can be reliably obtained. The shape of the groove is not particularly limited as long as it increases the holding force of the viscous fluid 70.

 A second contact 55 of a second cam mechanism 50, which will be described later, is attached to the center of the lower end of each lift member 62, and the input shaft is supported by the cooperation of the second contact 55 and the second cam 51, which will be described later. The rotational motion of 40 is converted into a linear motion in the vertical direction and transmitted to both lift members 62, 62, and the output section main body 61 reciprocates linearly in the vertical direction via both lift members 62, 62.

A pair of first contactors 46, 46 are combined, and by the cooperation of the first cam 42 and the pair of contactors 46, 46, the rotational movement of the input shaft 40 is unidirectional in the horizontal direction (article 75 Is converted to a linear motion in the conveyance direction) and transmitted to the output unit 60, and the output unit 60 reciprocates linearly in one horizontal direction (the conveyance direction of the article 75).

  The first cam 42 is a disc-shaped rib cam in which a rib 43 is formed in an annular shape on the peripheral surface, and one side surface of the rib 43 is formed on the first cam surface 44 over the entire circumference, and the other side surface is formed. The first contactor 46 is engaged with the first cam surface 44 and the second cam surface 45, respectively.

  The first cam surface 44 and the second cam surface 45 of the first cam 42 are each formed in the same curved surface that is curved (displaced) in the axial direction of the input shaft 40 and rises perpendicularly from the outer peripheral surface of the input shaft 40.

As described above, the horizontal distance between the cam followers 46 and 46 is adjusted.

  The two cam followers 46 and 46 are configured to be able to adjust the distance between them. By adjusting the distance between the two cam followers 46 and 46, the roller 48, the first cam surface 44, and the first cam surface 44 of each cam follower 46 are adjusted. The contact pressure with the two cam surfaces 45 can be adjusted to a predetermined value, and a pressurized state that does not cause backlash can be created.

  By driving the drive source 66 to rotationally drive the input shaft 40, the first cam 42 is rotationally driven integrally with the input shaft 40, and on the first cam surface 44 and the second cam surface 45 of the first cam 42. The roller 48 of each cam follower 46 rolls while maintaining a contact state, and both cam followers 46 and 46 are unidirectional in the horizontal direction (conveyance) according to the curved surface shape of the first cam surface 44 and the second cam surface 45. The output section main body 61 of the output section 60 is displaced in the same direction integrally with both cam followers 46, 46, and the transport section 2 attached to the upper part of the output section main body 61 is integrated with the output section 60. Reciprocates linearly in one horizontal direction (conveyance direction).

  In this case, the first cam surface 44 and the second cam surface 45 of the first cam 42 are formed as curved surfaces that rise vertically from the outer peripheral surface of the input shaft 40, and are formed on the first cam surface 44 and the second cam surface 45. Each of the cam followers 46 in contact with each other is configured such that the axis of the support shaft 47 is oriented in the vertical direction and the roller 48 is rotated in the horizontal direction around the axis of the support shaft 47. At the time of driving, as shown by a two-dot chain line in FIG. 11A, both cam followers 46 and 46 move in the vertical direction integrally with the output unit 60, so both cam followers 46 and 46 are perpendicular to the output unit 60. The reciprocating linear motion in the direction is not hindered, and the output unit 60 can smoothly reciprocate linearly in the vertical direction.

  As shown in FIGS. 8 to 10, the second cam mechanism 50 is provided integrally with both sides of the first cam 42 of the input shaft 40, and is a pair of second drives that are rotationally driven integrally with the input shaft 40. The pair of second cams 51, 51 and the pair of second contactors 55 are constituted by cams 51, 51, and a pair of second contactors 55, 55 that mutually engage with the second cams 51, 51. 55, the rotational motion of the input shaft 40 is converted into a vertical reciprocating linear motion and transmitted to the output unit 60, and the output unit 60 reciprocates linearly in the vertical direction.

  Each of the second cams 51 is a disk-shaped groove cam, and a groove 52 having a predetermined width and depth centering on the axis of the input shaft 40 is annularly formed on one side surface. And the outer surface is formed in the 1st cam surface 53 and the 2nd cam surface 54, respectively.

  The first cam surface 53 and the second cam surface 54 are curved in a direction orthogonal to the axis of the input shaft 40 and are formed in curved surfaces parallel to the axis of the input shaft 40. The first cam surface 53 and the second cam surface A roller 57 of the second contactor 55 is engaged in a rollable manner in a groove 52 having a surface 54. The 1st cam surface 53 and the 2nd cam surface 54 are formed in the curved surface mutually parallel over the perimeter, and the cam curve of the 2nd cam 51 is comprised by this curved surface.

  Similar to the first contact 46, the second contact 55 is a cam follower 55 and is attached to the center of the lower end of each shift member 62 of the output unit 60. Each second contact 55 is fitted to the center of the lower end of each shift member 62, horizontally by means such as screwing, and vertically by the support shaft 56. The support shaft 56 is mounted parallel to the axis of the input shaft 40. Each roller 57 is engaged with the groove 52 of each second cam 51, and the circumferential surface of each roller 57 is the first cam surface 53 and the second cam surface 54. Are in contact with each other in a rollable manner.

  By operating the drive source 65 to rotationally drive the input shaft 40, both the second cams 51, 51 are rotationally driven integrally with the input shaft 40 and are engaged in the grooves 52 of the respective second cams 51. The peripheral surface of the roller 57 of each second contact 55 rolls on the first cam surface 53 and the second cam surface 54, and both the second contacts 55, 55 are the first cams of both the second cams 51, 51.

Then, the first transport unit 2 attached to the upper portion of the output unit main body 61 performs a reciprocating linear motion in the vertical direction integrally with the output unit 60.

In this case, the first cam surface 53 and the second cam surface 54 of each second cam 51 are formed in a curved surface parallel to the axis of the input shaft 40 and are engaged in the groove 52 of each second cam 51. Since each cam follower 55 is mounted so that the axis of the support shaft 56 is parallel to the axis of the input shaft 40 and the roller 57 is rotatable in the vertical direction, the first cam mechanism 41 causes the output unit 60 to move horizontally. When the reciprocating linear motion is performed, as shown by a two-dot chain line in FIG. 11B, both the cam followers 55 and 55 are displaced in the horizontal direction integrally with the output unit, so that both the cam followers 55 and 55 are output unit. The reciprocating linear motion of 60 in the horizontal direction is not hindered, and the output unit 60 can smoothly reciprocate linearly in the horizontal direction.
Although not shown, the second cam may be constituted by a plate cam having a cam surface formed on the peripheral surface.

  Next, the operation of the article transport apparatus 1 according to the present embodiment configured as described above will be described with reference to FIGS. 1 and 12. Here, X1-X2 indicates horizontal movement displacement of the output unit 60, and Y4-Y3 indicates vertical movement displacement of the output unit 60.

  First, when the input shaft 40 is rotationally driven by the operation of the drive source 65, the first cam mechanism 41 converts the rotational motion of the input shaft 40 into a horizontal reciprocating motion, and the second cam mechanism 50 rotates the input shaft 40.

  Then, the posture of the article conveyed in the first conveyance path 4 is determined by the posture determination plates 11 a and 11 b in the posture determination unit 10, and the article in the normal posture passes through the posture determination unit 10 and is first transported. It continues to be transported in the path 4 and is supplied to the next process continuous to the first transport unit 2. On the other hand, the article 75 in an irregular posture (abnormal posture) comes into contact with the posture determination plate 11a and enters the second conveyance path 15 of the second conveyance unit 13 from the first conveyance path 4 through the discharge port 8.

Since the second transport unit 13 is vibrated by transmitting the vibration of the first transport unit 2, it is not necessary to provide a separate drive source to vibrate the second transport unit 13. Circulation and storage can be performed. Therefore, when the article supply line is configured, the entire line can be made compact, so that space can be saved.

  Further, the posture determination unit 10 is provided in the middle of the conveyance direction of the first conveyance unit 2, and the article 75 with an abnormal posture is excluded from the first conveyance path 4 of the first conveyance unit 2, and the article 75 with a normal posture is obtained.

Only the article 75 in a regular posture can be reliably supplied to the next process.

  Further, since the vibration is applied to the transport surface 5 of the first transport unit 2 by the cooperation of the first cam mechanism 41 and the second cam mechanism 50, the proper vibration is determined according to the conditions such as the material and the determination method. Can be imparted to the conveying surface 5, and even an article such as a difficult-to-align part with little shape feature can be conveyed.

  Further, the output unit 60, that is, the first transport unit 2 is moved only in one horizontal direction and in the vertical direction in cooperation with the side surfaces 63 and 63 of the lift member 62 and the guide surface 37 of the guide member 36 on the inner surface of the housing 31. Since it is guided so as to be capable of reciprocating linear movement, it is possible to always carry out stable and uniform conveyance over the entire conveyance surface 5 and to smoothly deliver the article 75 to and from the second conveyance unit 13. It becomes possible.

  Furthermore, even when the horizontal amplitude of the conveyance surface 5 such as conveyance of relatively large parts is required, stable conveyance with little flapping can be performed, and even such articles are aligned. In this state, it can be supplied to the next process.

  Further, the vibration of the conveying surface 5 is generated by the independent first cam mechanism 41 and the second cam mechanism 50 in the horizontal and vertical reciprocating linear motions (vibrations), respectively, and these two reciprocating linear motions (vibrations). Therefore, the vibrations do not interfere with each other, and an accurate and stable operation can be obtained by the two cam mechanisms 41 and 50.

  Furthermore, since the vibration for conveying the article 75 is given to the conveyance surface 5 by synthesizing the vibration of the biaxial system, it becomes possible to give a two-dimensional arbitrary locus to the conveyance surface 5. Versatility can be improved.

  Furthermore, since the first cam mechanism 41 and the second cam mechanism 50 can freely set arbitrary timings, the movement of the conveyance surface 5 that is most suitable for conveyance according to use conditions such as material and conveyance capacity. Can produce.

  Further, since the output unit 60 is guided so as to be displaced in two directions by the cooperation of the lift member 62 and the guide member 36, it is caused by additional fluctuation, pitching vibration of the conveyance surface 5, and bending of the conveyance surface 5. It is difficult to be affected by vibration or the like, and stable and uniform conveyance is always possible over the entire conveyance surface 5.

  Even in the article transport apparatus 1 shown in this embodiment, the second transport section 13 is connected to the first transport section 2 that transports the article 75 as in the case of the first embodiment. Since the second transport unit 13 is vibrated by transmitting the vibration of the first transport unit 2 to the second transport unit 13, it is necessary to provide a separate drive source to vibrate the second transport unit 13. Rather, articles can be aligned, circulated and stored in a compact configuration.

While being able to reduce, it can prevent that a line stops with the articles | goods 75 of an abnormal attitude | position, and can improve production efficiency.

  Further, the first transport mechanism 2 is vibrated by the cooperation of the first cam mechanism 41 and the second cam mechanism 50, and the second transport section 13 is also vibrated by the cooperation of both the cam mechanisms 41, 50. The vibration of the first transport unit 2 is not affected by the vibration of the second transport unit 13, and the article 75 can be transported accurately and efficiently, and the alignment function of the article 75 is not degraded. Only the article 75 in a regular posture can be reliably supplied to the next process.

  Further, since the vibration is applied to the transport surface 5 of the first transport unit 2 by the cooperation of the first cam mechanism 41 and the second cam mechanism 50, the proper vibration is determined according to the conditions such as the material and the determination method. Can be imparted to the conveying surface 5, and even an article such as a difficult-to-align part with little shape feature can be conveyed.

  Further, the output unit 60, that is, the first transport unit 2 is moved only in one horizontal direction and in the vertical direction in cooperation with the side surfaces 63 and 63 of the lift member 62 and the guide surface 37 of the guide member 36 on the inner surface of the housing 31. Since it is guided so as to be capable of reciprocating linear movement, it is possible to always carry out stable and uniform conveyance over the entire conveyance surface 5 and to smoothly deliver the article 75 to and from the second conveyance unit 13. It becomes possible.

  Furthermore, even when the horizontal amplitude of the conveyance surface 5 such as conveyance of relatively large parts is required, stable conveyance with little flapping can be performed, and even such articles are aligned. In this state, it can be supplied to the next process.

  Further, the vibration of the conveying surface 5 is generated by the independent first cam mechanism 41 and the second cam mechanism 50 in the horizontal and vertical reciprocating linear motions (vibrations), respectively, and these two reciprocating linear motions (vibrations). Therefore, the vibrations do not interfere with each other, and an accurate and stable operation can be obtained by the two cam mechanisms 41 and 50.

  Furthermore, since the vibration for conveying the article 75 is given to the conveyance surface 5 by synthesizing the vibration of the biaxial system, it becomes possible to give a two-dimensional arbitrary locus to the conveyance surface 5. Versatility can be improved.

  Furthermore, since the first cam mechanism 41 and the second cam mechanism 50 can freely set arbitrary timings, the movement of the conveyance surface 5 that is most suitable for conveyance according to use conditions such as material and conveyance capacity. Can produce.

 Further, since the output unit 60 is guided so as to be displaced in two directions by the cooperation of the lift member 62 and the guide member 36, it is caused by additional fluctuation, pitching vibration of the conveyance surface 5, and bending of the conveyance surface 5. It is difficult to be affected by vibration or the like, and stable and uniform conveyance is always possible over the entire conveyance surface 5.

  Furthermore, since the 2nd conveyance part 13 is each provided in the both sides of the 1st conveyance part 2, the storage amount of the goods 75 in the 2nd conveyance path 15 can be increased rather than what is shown in 1st Embodiment. .
