The sub posture changing fluid ejection hole is formed so that the fluid is ejected from the sub transport path surface in a direction different from the sub transport fluid ejection hole, and the posture of the workpiece on the sub transport path surface is an irregular posture. Sub-guide means for guiding the workpiece along the sub-transport path surface is provided at a sub-posture change position for converting the state into the normal posture state.

  According to a third aspect of the present invention, in the second aspect of the present invention, the sub posture changing fluid ejection hole may be any one of a range from a direction orthogonal to the sub transport direction to an upstream direction of the sub transport direction. The fluid is characterized in that the fluid is ejected obliquely from the sub-transport path surface toward the direction, or is ejected vertically from the sub-transport path surface.

  The invention according to claim 4 is the invention according to claim 2 or 3, wherein the sub-transport road surface member has a position downstream of the sub-posture conversion position on the sub-transport path surface in the sub-transport direction. In order to discharge the workpiece in the irregular posture state to the outside in the width direction of the sub-transport path surface, a sub-discharge fluid jet hole for ejecting the fluid is provided, and the sub-discharge fluid jet hole is The fluid is formed so as to be ejected obliquely from the sub-transport path surface toward the outside in the width direction on the sub-transport path surface.

  The invention according to claim 5 is configured to convey the work, in which one end of the cylindrical portion is closed by the end surface portion, by the fluid, and is configured to be in a constant posture state in the conveyance process. A workpiece transfer and orientation control device, a main transfer path extending along a main transfer direction, and a main transfer fluid for ejecting the fluid from the main transfer path to transfer the workpiece in the main transfer direction In order to convert the workpiece in an irregular posture state other than the workpiece in a normal posture state in which the ejection hole and the end surface portion are directed to the main conveyance road surface side, the fluid is transferred to the main conveyance road surface. A main conveyance path surface member having a main posture changing fluid ejection hole ejecting from the main conveyance fluid ejection hole obliquely from the main conveyance path surface toward the downstream side in the main conveyance direction. A plurality of main posture changing fluid ejection holes are formed along the main transport direction and eject the fluid from the main transport path surface in a direction different from the main transport fluid ejection hole. The main guide means that guides the workpiece along the main conveyance road surface at a main posture conversion position that converts the posture of the workpiece on the main conveyance road surface from the irregular posture state to the normal posture state. It is characterized by being provided.

  The invention according to claim 6 is the invention according to claim 5, wherein the main posture changing fluid ejection hole is any one in a range from a direction orthogonal to the main transport direction to an upstream direction of the main transport direction. It is characterized by being formed so as to be ejected obliquely from the main transport path surface toward the direction or to be ejected vertically from the main transport path surface.

  The invention according to claim 7 is the invention according to claim 5 or 6, wherein the main transport path surface member has a position on the downstream side in the main transport direction from the main posture conversion position on the main transport path surface. In order to discharge the workpiece in an irregular posture outward in the width direction of the main conveyance path surface, a downstream main discharge fluid ejection hole for ejecting the fluid is provided, and the downstream main discharge fluid ejection The hole is formed so that the fluid is ejected obliquely from the main transport path surface toward the outside in the width direction on the main transport path surface.

  According to the invention described in claim 1 configured as described above, when fluid is ejected obliquely from the plurality of main transport fluid ejection holes on the main transport path surface toward the downstream side in the main transport direction, for example, the end surface portion is For a workpiece in a normal posture directed to the main conveyance path surface side, the fluid becomes a thin film-like high-speed fluid between the end surface portion and the main conveyance path surface and flows downstream in the main conveyance direction. Become. For this reason, the workpiece in the normal posture is in a stable state in which the end face is adsorbed to the main conveyance path surface because the thin film-like high-speed fluid becomes negative pressure, and is almost equal to the flow velocity of the high-speed fluid. It is transported downstream in the main transport direction at a speed.

  Further, the fluid ejected obliquely from the main transport fluid ejection hole has a partial speed in a direction of flowing out vertically from the main transport path surface, and a partial speed in a direction of flowing parallel to the main transport path surface toward the downstream side in the main transport direction. Therefore, a workpiece in an irregular posture state other than a workpiece whose end face portion is directed to the main conveyance path surface side can be maintained in a floating state from the main conveyance path surface and is conveyed in the main conveyance direction. Can do.

  However, since the workpiece in the irregular posture state is not attracted to the main conveyance path surface by the fluid, it is conveyed in an unstable state.

  For this reason, the workpiece in the irregular posture state is easily discharged from the main transport path surface by the fluid ejected obliquely with respect to the main transport path surface from the main discharge fluid ejection hole in the width direction of the main transport path surface. can do.

  That is, the fluid ejected from the main discharge fluid ejection hole has a partial velocity in a direction of flowing out vertically from the main transport path surface and flows parallel to the main transport path surface toward the outside in the width direction of the main transport path surface. Therefore, the workpiece can be floated with respect to the main conveyance path surface and can be easily carried out to the outside.

  Also, the workpiece in the normal posture state is affected by the fluid ejected from the main discharge fluid ejection hole, but in the main transport direction while being sucked to the main transport path surface by the fluid ejected from the main transport fluid ejection hole. Therefore, it is not discharged from the main conveyance path surface.

  Therefore, the work arranged in the normal posture state can be transported to the downstream side in the main transport direction without using the posture requisite device that has been essential in the past, so that the size can be reduced and the cost can be reduced. Can be achieved.

  According to the second aspect of the present invention, the base end portion is connected to the main discharge position from which the work on the main transport path surface is discharged, and the tip end portion is downstream in the main transport direction from the main discharge position on the main transport path surface. A sub-transport road surface member connected to a main confluence position located in the sub-transport road surface member, the sub-transport road surface member extending along the sub-transport direction from the base end to the tip end, and a main discharge A sub-conveying fluid ejection hole for ejecting fluid from the sub-conveying path surface to convey the work discharged from the position to the base end portion downstream in the sub-conveying direction, and a work in an irregular posture state is converted into a normal posture state. For this purpose, it has a sub attitude conversion fluid ejection hole for ejecting fluid from the sub conveyance path surface, so that the workpiece in the irregular posture state discharged from the main conveyance path surface is converted to the normal posture state and then returned to the main conveyance path surface again Can be returned.

  In this case, conversion of the posture of the workpiece from the irregular posture state to the regular posture state can be easily performed by the fluid ejected from the sub posture changing fluid ejection hole and ejected in a direction different from the sub transport fluid ejection hole. Can be done.

  That is, the workpiece in the irregular posture state is conveyed to the downstream side in the irregular posture state by the fluid ejected from the sub conveyance fluid ejection hole, but is different from the sub conveyance fluid ejection hole from the sub posture conversion fluid ejection hole. When the fluid is ejected in the direction, the flow of the fluid ejected from the sub posture changing fluid ejection hole and the sub transport fluid ejection hole is stagnant, and the flow of these fluids moving upward in the vertical direction from the sub transport path surface It becomes. In addition, the rotational force acts on the workpiece due to the interaction of the fluid ejected from the sub posture changing fluid ejection hole and the sub transport fluid ejection hole.

  For this reason, the workpiece in the irregular posture state once moves upward and rotates, and descends onto the sub-conveying road surface with the end face portion near the center of gravity directed downward. Thereby, the workpiece can be converted from the irregular posture state to the regular posture state.

  When the posture is changed, the workpiece in the irregular posture state where the end surface portion faces upward with respect to the sub-transport road surface is affected by the flow of fluid upward from the sub-transport route surface or the fluid ejected from each jet outlet. Since it is greatly affected by the rotational force due to the interaction, it moves higher upward and is rotationally driven with a large torque. Therefore, the upper end surface portion can be easily converted to the lower sub-transport road surface side.

  On the other hand, the work in an irregular posture state in which the cylindrical portion is oriented substantially parallel to the sub-transport road surface, the light side in the cylindrical portion moves upward due to the upward flow in the vertical direction from the sub-transport route surface, It will receive to the influence of the said rotational force by interaction of the fluid which ejects from each jet nozzle. Therefore, even in the case of a workpiece in such an irregular posture state, the end surface portion can be easily converted to the lower sub-transport road surface side.

  When the workpiece is thus converted to the normal posture state, the fluid ejected from the sub-transport fluid ejection hole flows as a thin film-like high-speed fluid between the end surface portion of the work and the sub-transport path surface. For this reason, after converting into the normal posture state, the workpiece can be transported to the downstream side in the sub transport direction in a stable state in which the work is adsorbed on the sub transport path surface.

  In addition, sub-guide means for guiding the work along the sub-transport road surface is provided at the sub-posture conversion position for converting the work posture on the sub-transport road surface from the irregular posture state to the normal posture state. When converted, it is possible to prevent the workpiece from falling from the sub-transport road surface.

  According to the third aspect of the present invention, the sub posture changing fluid ejection hole is slanted from the sub transport path surface in any direction in the range from the direction orthogonal to the sub transport direction to the upstream direction of the sub transport direction. Or the sub-conveying fluid ejection hole and the sub-conveying fluid ejection hole can partially stagnate partially. The flow of the fluid rising in the vertical direction from the sub-transport path surface can be made sufficiently. In addition, a large rotational force can be applied to the workpiece by the interaction of the fluid ejected from the sub posture changing fluid ejection holes and the sub transport fluid ejection holes.

  In the case of the sub posture changing fluid ejection hole for ejecting the fluid vertically from the sub transport path surface, the flow of the fluid rising in the vertical direction from the sub transport path surface can be directly obtained.

  Therefore, the workpiece in the irregular posture state can be more reliably converted to the regular posture state.

  According to the fourth aspect of the present invention, the workpiece in the irregular posture state is discharged to the outside in the width direction of the sub-transport road surface at a position downstream of the sub-posture conversion position on the sub-transport road surface in the sub-transport direction. Is provided with a sub-discharge fluid ejection hole for ejecting fluid, and the sub-discharge fluid ejection hole is formed so that the fluid is ejected obliquely from the sub-transport path surface toward the outside in the width direction of the sub-transport path surface. Therefore, even if the workpiece is not converted to the normal posture state at the secondary posture conversion position and the workpiece in the irregular posture state remains, move the workpiece in the irregular posture state to the outside of the secondary conveyance road surface. Can be discharged. The reason why only the workpiece in the irregular posture state can be discharged is that the same action as that of the main discharge fluid ejection hole and the main transfer fluid ejection hole described above can be generated.

  Therefore, only the workpiece converted into the normal posture state can be returned to the main conveyance road surface.

  According to the fifth aspect of the present invention, the workpiece in the irregular posture state can be converted into the regular posture state by the fluid ejected from the main posture changing fluid ejection hole. The reason why the workpiece can be converted from the irregular posture state to the normal posture state is that the same action as the action by the sub posture changing fluid ejection hole and the sub transport fluid ejection hole described above can be generated. .

  In addition, main guide means for guiding the work along the main transport road surface is provided at the main posture conversion position that converts the posture of the work on the main transport road surface from the irregular posture state to the normal posture state. It is possible to prevent the workpiece from falling from the main conveyance path surface.

  Therefore, the work arranged in the normal posture state can be transported to the downstream side in the main transport direction without using the posture requisite device that has been essential in the past, so that the size can be reduced and the cost can be reduced. Can be achieved.

  According to the sixth aspect of the present invention, the fluid is obliquely inclined from the main conveyance path surface in any direction in the range from the direction perpendicular to the main conveyance direction to the upstream direction of the main conveyance direction. Therefore, the workpiece can be reliably converted from the irregular posture state to the regular posture state. The reason why the workpiece can be reliably converted into the normal posture state in this way is that the same action as that of the sub attitude changing fluid ejection hole and the sub transport fluid ejection hole described above can be generated.

  According to the seventh aspect of the present invention, the workpiece in the irregular posture state is discharged to the outside in the width direction of the main transport road surface at a position downstream of the main posture conversion position on the main transport road surface in the main transport direction. Is provided with a downstream main discharge fluid ejection hole for ejecting fluid, and the downstream main discharge fluid ejection hole ejects the fluid obliquely from the main conveyance path surface toward the outer side in the width direction of the main conveyance path surface. Therefore, even when the workpiece is not converted to the normal posture state at the main posture conversion position, the workpiece in the irregular posture state can be discharged to the outside of the main conveyance road surface. The reason why only the workpiece in the irregular posture state can be discharged is that the same action as that of the main discharge fluid ejection hole and the main transfer fluid ejection hole described above can be generated.

  Therefore, only the workpiece converted into the normal posture state can be transported to the downstream side of the main transport road surface.

  In addition, a compressed air supply passage (not shown) is formed below the main conveyance path surface member 1 and the sub conveyance path surface member 2, and the main conveyance fluid ejection hole 12 and the main discharge passage are formed from the supply flow path. Air A is supplied to the fluid ejection holes 13, the sub-carrier fluid ejection holes 22, the sub attitude changing fluid ejection holes 23, the sub-discharge fluid ejection holes 24, and the like.

  Note that the cap W discharged from the opening 25a is reintroduced to the upstream side of the main conveyance path surface 11 sequentially or after a predetermined amount has been accumulated.

  In the workpiece conveying and posture arranging apparatus configured as described above, as shown in FIG. 2, the plurality of main conveying fluid ejection holes 12 on the main conveying path surface 11 are obliquely inclined toward the downstream side in the main conveying direction 11a. When the air A is ejected, for example, for the cap W in a normal posture, the air A becomes a film-like high-speed fluid between the end surface W2 and the main transport path surface 11 and flows downstream in the main transport direction 11a. It will be. For this reason, the cap W in the normal posture state is in a stable state in which the end surface portion W2 is adsorbed to the main transport path surface 11 because the high-speed fluid due to the air A becomes negative pressure, and the end surface portion W2 and the main transport The air is transported to the downstream side in the main transport direction 11a at a speed substantially equal to the speed of the air A flowing between the road surface 11.

  Further, the air A ejected obliquely from the main transport fluid ejection hole 12 has a velocity component in a direction ejected perpendicularly from the main transport path surface 11 and is parallel to the main transport path surface 11 toward the downstream side of the main transport direction 11a. Therefore, the cylindrical portion W1 is substantially parallel to the main transport path surface 11 even with the cap W in the irregular posture state in which the end surface portion W2 is positioned above the main transport path surface 11. The cap W in the irregular posture located at the position can be kept floating from the main transport path surface 11 and can be transported in the main transport direction 11a.

  However, since the cap W in the irregular posture state is not sucked into the main transport path surface 11 by the air A, the cap W is transported in an unstable state.

  For this reason, the cap W in the irregular posture state is caused by the air A jetted obliquely with respect to the main transport path surface 11 outward from the main discharge fluid ejection hole 13 in the width direction of the main transport path surface 11. It can be easily discharged from the road surface 11.

  That is, as shown in FIG. 3, the air A ejected from the main discharge fluid ejection hole 13 has a partial speed in a direction of ejecting vertically from the main transport path surface 11 and outward in the width direction of the main transport path surface 11. The cap W in an irregular posture state in which the end surface W2 is located above the main transport path surface 11 because of the partial speed in the direction of jetting parallel to the main transport path surface 11 (see FIG. 3A). ), The cap W (see FIG. 3B) in an irregular posture in which the cylindrical portion W1 is positioned substantially parallel to the main transport path surface 11 can also be floated with respect to the main transport path surface 11. At the same time, it can be easily carried out to the outer sub-transport road surface 21 side.

  Further, the cap W in the normal posture state is affected by the air A ejected from the main discharge fluid ejection hole 13, but is sucked into the main transport path surface 11 by the air A ejected from the main transport fluid ejection hole 12. Therefore, without being discharged from the main conveyance path surface 11, it is stably moved to the downstream side in the main conveyance direction 11a.

  For this reason, only the cap W arranged in the normal posture state can be transported downstream in the main transport direction 11a. In other words, when the cap W arranged in the normal posture state is transported to the downstream side of the main transport road surface 11, the conventionally required posture rearranging device becomes unnecessary.

  Further, a sub-transport road surface member 2 having a base end portion 2a connected to the main discharge portion 11b and a tip end portion 2b connected to the main junction portion 11c is provided. The sub-transport road surface member 2 extends along the sub-transport direction 21a. The existing sub-transport road surface 21, the sub-transport fluid ejection hole 22 for transporting the cap W discharged from the main discharge portion 11b to the sub-transport path surface 21 to the downstream side in the sub-transport direction 21a, and the cap in the irregular posture state. A sub-posture change fluid ejection hole 23 for converting W into a normal posture state, and a cap W in an irregular posture state at a position downstream of the sub-posture change fluid jet hole 23 in the sub-transport direction 21a. 21 has a sub-discharge fluid ejection hole 24 for discharging outward in the width direction, so that the cap W in the irregular posture state discharged from the main transport path surface 11 is converted into the regular posture state. Return to the main transport surface 11 again It is possible.

  In this case, the posture change of the cap W from the irregular posture state to the regular posture state is the air A ejected from the sub posture transforming fluid ejection hole 23 and the air ejected in a direction different from the sub transport fluid ejection hole 22. A can be easily performed.

  That is, the cap A in the irregular posture state moves to the downstream side in the sub-transport direction 21a in an unstable state by the air A ejected from the sub-transport fluid ejection hole 22, but the sub posture in the sub posture conversion unit 21b When the air A is ejected from the conversion fluid ejection hole 23, a braking force is applied to the cap W, and the flow of the air A ejected from the sub attitude conversion fluid ejection hole 23 and the sub-carrier fluid ejection hole 22 is delayed. These air A flows from the sub-transport path surface 21 upward in the vertical direction. In addition, the rotational force acts on the cap W by the interaction of the fluid ejected from the sub posture changing fluid ejection hole 23 and the sub transport fluid ejection hole 22.

  For this reason, as shown in FIGS. 5A to 5D, the cap W in the irregular posture state once moves upward and rotates, and then the sub-transport on the downstream side of the sub posture changing fluid ejection hole 23. At this time, as shown in FIG. 5D, the end surface W2 close to the center of gravity G of the cap W is lowered onto the sub-transport road surface 21 in a state of facing downward. become. That is, the cap W can be converted from the irregular posture state to the regular posture state.

  In this case, the cap W in the irregular posture state in which the end surface portion W2 is positioned above the sub-transport path surface 21 has a flow of the air A that moves upward in the vertical direction from the sub-transport path surface 21 and the ejection holes 23 and 22. Since it is greatly affected by the rotational force due to the air A ejected from the air, it moves greatly upward and is driven to rotate greatly. Therefore, it is possible to reliably convert the upper end surface portion W2 so as to be positioned on the lower sub-transport path surface 21 side.

  Further, the cap W in the irregular posture state in which the cylindrical portion W1 is positioned substantially parallel to the sub-transport path surface 21 has a flow of air A that moves upward in the vertical direction from the sub-transport path surface 21 and the ejection holes 23 and 22. The light side of the cylindrical portion W1 moves upward due to the influence of the rotational force caused by the air A ejected from the upper side, and the end surface portion W2 on the heavy side becomes the lower position. Therefore, even in the case of the cap W in such an irregular posture state, the end surface portion W2 can be easily converted to the sub-transport road surface 21 side.

  When the cap W is converted to the normal posture state in this way, the air A ejected from the sub-carrier fluid ejection hole 22 becomes a film-like high-speed fluid between the end surface portion W2 of the cap W and the sub-carrier path 21. Therefore, the cap W after being converted to the normal posture state can be maintained in a stable state in which the cap W is attracted to the main transport path surface 11 and can be transported downstream in the sub transport direction 21a. it can.

  In addition, as shown in FIG. 6, the sub posture conversion unit 21 b is provided with a sub guide wall 25 that guides the cap W along the sub transport path surface 21. It is possible to prevent the cap W from dropping from the sub-transport road surface 21 when the posture is changed by descending.

  In particular, since the sub posture changing fluid ejection hole 23 is formed so as to eject the air A obliquely from the sub conveyance path surface 21 in a direction orthogonal to the sub conveyance direction 21 a, The ejected air A has an advantage that the cap W can be raised higher from the sub-transport path surface 21 and a larger rotational force can be applied to the cap W.

  For this reason, the cap W can be reliably converted from the irregular posture state to the regular posture state.

  In addition, since the sub discharge fluid ejection hole 24 is provided in the sub discharge portion 21c, even if the cap W is not converted to the normal posture state in the sub posture converting portion 21b, it is irregular. The cap W in the posture state can be discharged to the outside of the sub transport road surface 21. The reason why only the cap W in the irregular posture state can be discharged is because the same action as that of the main discharge fluid ejection hole 13 and the main transport fluid ejection hole 12 described above occurs.

  Therefore, since only the cap W converted into the normal posture state can be returned to the main transporting road surface 11, only the cap W in the normal posture state can be sent to the capping machine. In addition, in this case, since the posture rearranging device that has been essential in the past is not necessary, the device can be reduced in size and the cost can be reduced. .

  Further, as shown in FIG. 7, the cap W in the normal posture state is converted into a state in which the opening portion is directed downward via the up-and-down conversion device 3, and then the bottle mouth is opened in a capping machine (not shown). It will be attached to the part.

{Different forms for carrying out the invention}

(Second Embodiment)
Next, 2nd Embodiment as a different form for implementing this invention is described with reference to FIG. However, elements that are the same as those shown in the first embodiment are denoted by the same reference numerals, and description thereof is simplified.

  The second embodiment differs from the first embodiment in that the cap W is converted into the normal posture state and converted into the normal posture state only in the main transport road surface member 1 without providing the sub-transport road surface member 2. It is the point which is the structure which discharges only the cap W which did not exist.

  That is, the main conveyance path surface member 1 is not provided with the main discharge portion 11b, the main junction portion 11c, the main discharge fluid ejection hole 13 and the openings 15a and 15b described above, and the irregularities other than the cap W in the normal posture state. In order to convert the cap W in the posture state into the normal posture state, a main posture conversion fluid ejection hole 16 that ejects air A from the main conveyance path surface 11, and a main posture conversion section provided with the main posture conversion fluid ejection hole 16 (Main posture conversion position) A downstream main member that is provided downstream of the main transport direction 11a from the main transport direction 11d and ejects air A to discharge the cap W in the irregular posture state outward in the width direction of the main transport path surface 11. And a discharge fluid ejection hole 17.

  The main posture conversion fluid ejection hole 16 is formed so as to eject air A from the main conveyance path surface 11 in a direction different from that of the main conveyance fluid ejection hole 12. In particular, the main posture changing fluid ejection hole 16 shown in this embodiment is configured to cause the air A to be inclined from the main transport path surface 11 in a direction orthogonal to the main transport direction 11a (in this embodiment, relative to the main transport path surface 11) It is formed so as to be ejected obliquely in the direction of 10 to 45 degrees.

  That is, the main posture changing fluid ejection hole 16 opens to the lower surface 14 (see FIG. 2) and the main conveyance path surface 11 of the main conveyance path surface member 1 and linearly extends between the lower surface 14 and the main conveyance path surface 11. It is inclined so as to be located on one side of the direction perpendicular to the main transport direction 11a as it extends toward the main transport path surface 11. And the inclination-angle with respect to the main conveyance path surface 11 of the main attitude | position conversion fluid ejection hole 16 is set to 10 to 45 degree | times as mentioned above.

  Further, the main posture changing fluid ejection hole 16 opens at a position substantially at the center of the opening portions of the two closest main conveyance fluid ejection holes 12 on the center line C1 of the main conveyance path surface 11, and air is passed through the opening. A is ejected.

  In addition, the main guide wall 15 in the main posture conversion unit 11d guides the cap W along the main transport path surface 11, so that the cap W can be used to convert the posture from the irregular posture state to the normal posture state. 11 as well as a guide for changing the posture.

  The downstream main discharge fluid ejection hole 17 is provided in a downstream main discharge portion (downstream main discharge position) 11e located on the downstream side of the main posture changing portion 11d in the main transport path surface member 1, and air A Inclined from the main conveyance path surface 11 toward the outside of one side of the main conveyance path surface 11 in the width direction (in this embodiment, outward in the right direction toward the downstream side of the main conveyance direction 11a) (this embodiment) Are formed so as to be ejected obliquely in the direction of 10 to 45 degrees with respect to the main transport path surface 11.

  That is, the downstream main discharge fluid ejection holes 17 open to the lower surface 14 and the main conveyance path surface 11 of the main conveyance path surface member 1 and extend linearly between the lower surface 14 and the main conveyance path surface 11. In addition, it is inclined so as to gradually be located outward as it goes toward the main conveyance path surface 11. The inclination angle of the downstream main discharge fluid ejection hole 17 with respect to the main conveyance path surface 11 is set to 10 to 45 degrees as described above.

  In addition, the downstream main discharge fluid ejection hole 17 has a center line C1 on the main transport path surface 11 and the other side in the width direction on the main transport path surface 11 (in this embodiment, the left side toward the downstream side of the main transport direction 11a). ) And the main guide wall 15, the air A is ejected from the opening.

  Further, the air A ejected from the downstream main discharge fluid ejection hole 17 is the two main transport fluids closest to the opening of the main transport fluid ejection hole 12 in a plan view when the main transport path surface 11 is viewed from above. It passes through the center between the openings of the ejection holes 12.

  However, the magnitude and direction of the flow velocity of the air A ejected from the downstream main discharge fluid ejection hole 17 are the air A and each main carrier fluid ejected from the downstream main discharge fluid ejection hole 17 in the plan view. It is set so that the flow combined with the air A ejected from the ejection holes 12 passes through the central portion in the main transport direction 11a direction in the opening 15c described later.

  An opening 15c for discharging the cap W in an irregular posture state from the main transport path surface 11 is formed in the main guide wall 15 on one side in the width direction of the main transport path surface 11 in the downstream main discharge section 11e. Yes.

  Note that the cap W discharged from the opening 15c is reintroduced to the upstream side of the main conveyance path surface 11 after being accumulated sequentially or after a predetermined amount.

  In the workpiece conveying and posture arranging apparatus configured as described above, the cap W in the irregular posture state conveyed on the main conveyance road surface 11 to the main posture converting fluid ejection hole 16 is converted into the normal posture state. Can do. The reason why the cap W can be converted from the irregular posture state to the regular posture state is that the same action as the action by the sub attitude changing fluid ejection hole 23 and the sub transport fluid ejection hole 22 described above occurs.

  Further, since the main guide wall 15 is provided in the main posture changing portion 11d, it is possible to prevent the cap W from falling from the main transport path surface 11 during posture changing. The reason why the cap W can be maintained on the main conveyance path surface 11 is that the same action as that of the sub guide wall 25 described above occurs.

  Further, since the downstream main discharge fluid ejection hole 17 is provided in the downstream main discharge portion 11e downstream of the main posture changing portion 11d on the main transport path surface 11, the cap W is extended in the main posture changing portion 11d. Even when it is not converted into the one normal posture state, only the cap W in the irregular posture state can be discharged to the outside of the main conveyance road surface 11. The reason why only the cap W in the irregular posture state can be discharged is because the same action as that of the main discharge fluid ejection hole 13 and the main transport fluid ejection hole 12 described above occurs.

  Therefore, since only the cap W converted into the normal posture state can be transported to the downstream side of the main transport path surface 11 without using the sub transport path surface member 2, the apparatus can be further reduced in size and cost. Can do.

  In each of the above embodiments, the sub posture changing fluid ejection hole 23 is configured to eject air A in a direction orthogonal to the sub transport direction 21a (center line C2), and the main posture changing fluid ejection hole 16 is formed as the main posture changing fluid ejection hole 16. The air A is configured to be ejected in a direction orthogonal to the transport direction 11a (center line C1). However, the sub attitude conversion fluid ejection holes 23 or the main attitude conversion fluid ejection holes 16 are arranged in the sub transport direction 21a or the main transport. Air A is jetted obliquely from the sub-transport path surface 21 or the main transport path surface 11 in any direction in the range from the direction orthogonal to the direction 11a to the sub-transport direction 21a or the upstream direction of the main transport direction 11a. Or you may form so that it may eject from the sub conveyance path surface 21 or the main conveyance path surface 11 perpendicularly | vertically.

  As the direction in which the air A is ejected is directed to the upstream side of the sub-transport direction 21a or the main transport direction 11a, the effect of moving the cap W upward by the jet of air A increases and the sub-transport fluid ejection The effect of applying a rotational force to the cap W is enhanced by the interaction with the air A ejected from the hole 22 or the main transport fluid ejection hole 12.

  Further, when the auxiliary posture changing fluid ejection hole 23 or the main posture changing fluid ejection hole 16 for ejecting the air A vertically from the sub conveying path surface 21 or the main conveying path surface 11 is provided, the effect of raising the cap W is further improved. Get higher.

  Moreover, although the example which used air as a fluid ejected from each ejection hole 12, 13, 16, 17, 22, 23, 24 was shown, it says that liquids, such as other gas and water, may be used. Not too long.
