Further, a bearing 37a on the inner end side of the horizontal pin 36 of the container presser 32 is mounted on the outer peripheral edge of the upper surface of the fixed plate 39 so as to be able to roll.
[0038]
Further, as shown in FIG. 3, a vertical operation cam 40 of the container presser 32 is partially attached to the outer peripheral edge side of the upper surface of the fixed plate 39 so as to protrude upward. As shown in FIG. 4A, the up / down operation cam 40 is formed in a substantially arc shape along the rotation path of the bearing 37a inside the container presser 32 as viewed from above. Further, as shown in FIG. 4B, the up / down operation cam 40 is provided with a substantially chevron-shaped protrusion 40b on the base surface 40a.
[0039]
A compression coil spring 41 is disposed around the support shaft 33 of the container holder 32 between the upper table 31 and the container holder body 34. The bearing 37 a on the inner end side of the horizontal pin 36 is always urged in a direction to be pressed against the outer peripheral edge of the upper surface of the fixed plate 39 by the spring force of the compression coil spring 41 and the weight of the container holder 32.
[0040]
A flat spindle guide 42 is attached to the outer periphery of the upper end of the guide tube 35. As shown in FIG. 4C, the spindle guide 42 is formed with a long hole 43 extending along the axial direction of the support shaft 33. A bearing 37 b on the outer end side of the horizontal pin 36 is inserted into the elongated hole 43. Thereby, the rotation prevention of the horizontal pin 36 is performed. When the turntable 15 rotates, the bearing 37 a on the inner end side of the horizontal pin 36 rotates along the outer peripheral edge of the upper surface of the fixed plate 39 as the upper table 31 that rotates integrally with the turntable 15 rotates. Move. At this time, when the bearing 37a on the inner end side of the horizontal pin 36 passes over the vertical operation cam 40 partially attached to the outer peripheral edge of the upper surface of the fixed plate 39, the vertical operation cam 40 The container presser 32 is raised by pushing up the bearing 37a. Thereby, the raising / lowering operation of the container holder 32 is controlled by the up / down operation cam 40. Then, the container presser body 34 of the container presser 32 is brought into contact with the mouth part 6 of the container 1 on the rotary table 16 and is held in a state where the mouth part 6 of the container 1 is pressed from above by the container presser body 34. It has become so. In this state, the rotary table 16 is driven to rotate, whereby the container 1 with a handle on the rotary table 16 is driven to rotate one or more times along the container receiver 16a.
[0041]
Further, a stopper support base 44 is disposed on one end portion side of the container receiver 16a in the vicinity of each rotary table 16. A stopper 45 is provided on the upper portion of the stopper support 44 so as to come into contact with a non-circular portion such as a portion where the handle portion 5 of the container 1 is formed.
[0042]
As shown in FIGS. 5A and 5B, the stopper 45 includes a swing member 47 supported so as to be rotatable about a swing shaft 46 extending in a substantially horizontal direction, and the swing member. 47 is provided with a vertically swinging lever type stopper body 48 fixed to 47, and a tension spring 49 for biasing the stopper body 48 in a direction in which the stopper body 48 is brought into contact with the non-circular portion of the container 1 with a handle on the rotary table 16. It has been. Here, the swing shaft 46 of the stopper 45 is pivotally supported by a bearing portion 44a on the upper portion of the stopper support base 44 as shown in FIG. Further, the stopper body 48 is detachably attached to the swing member 47 by a screw member 50.
[0043]
Further, the stopper main body 48 of the stopper 45 is always urged by the spring force of the tension spring 49 in the direction of turning counterclockwise in FIG. When the rotary table 16 is rotated, the stopper main body 48 of the stopper 45 is locked to the locking portion 5a formed by one side of the handle portion 5 as shown in FIGS. 5 (A) and 5 (B). Thus, the rotation of the container 1 with the handle on the turntable 16 is stopped.
[0044]
An air valve 51 for controlling the operation of the air clutch 22 is disposed on the inner side of the upper table 31. Further, a valve cam 52 for operating the air valve 51 is partially attached to the lower surface on the inner side of the fixed plate 39 so as to protrude downward. Here, the valve cam 52 is attached only to the section where each rotary table 16 needs to be rotated. The air valve 51 rotates integrally with the upper table 31, and the air valve 51 is turned on by the valve cam 52 only in a section where the rotation table 16 needs to be rotated when the air valve 51 is rotated. The connecting rotary tables 16 are rotated.
[0045]
Next, the operation of the present embodiment having the above configuration will be described. When the rotary container attitude control device 7 of the present embodiment is driven, the driving force from the drive gear 17 is transmitted, and the turntable 15 is rotated (revolved) around the main shaft 14. At this time, the container 1 before being attached with the cap supplied from the container supply conveyance line 9 is continuously fed from the feeding device 10 such as a star wheel to the entrance of the attitude control device 7.
[0046]
Further, the container 1 fed from the feeding position to the entrance of the attitude control device 7 is placed on the rotary table 16 in a state of being received by the container receiver 16a, and can be rotated around the rotation axis 18 about the axis. Supported by At this time, the directions of the handle portion 5 of the container 1 are different. Further, the stopper 45 is brought into contact with the outer peripheral surface of the container 1 on the table 16 at the same time when the container 1 is fed. Here, the stopper main body 48 of the stopper 45 is brought into contact with the outer peripheral surface of the container 1 on the table 16 while being stroked.
[0047]
In this state, the container 1 on each table 16 is rotated (revolved) in the counterclockwise direction in FIG. 1 along the rotation path about the main shaft 14 by the turntable 15. When the turntable 15 rotates, one idle gear 21a is driven to rotate along the fixed gear 20, and the rotation of the idle gear 21a is transmitted to the spindle gear 19 via the other idle gear 21b.
[0048]
The rotation of the spindle gear 19 is transmitted to the rotary shaft 18 of the rotary table 16 via the air clutch 22. The air clutch 22 is intermittently operated as the air valve 51 operates. When the air valve 51 is held in the OFF state, the air clutch 22 is held in the disconnected state. When the air clutch 22 is thus disconnected, the rotation of the spindle gear 19 is not transmitted to the rotary shaft 18 of the rotary table 16, and the rotary table 16 is held in a stopped state.
[0049]
Further, during rotation of the turntable 15, the upper table 31 rotates integrally with the turntable 15. As the upper table 31 rotates, the bearing 37 a on the inner end side of the horizontal pin 36 rolls along the outer peripheral edge of the upper surface of the fixed plate 39. At this time, when the bearing 37a on the inner end side of the horizontal pin 36 passes over the vertical operation cam 40 partially attached to the outer peripheral edge of the upper surface of the fixed plate 39, the vertical operation cam 40 The bearing holder 32 is pushed up, and the container holder 32 is raised. Thereby, the raising / lowering operation of the container holder 32 is controlled by the up / down operation cam 40.
[0050]
Further, during the rotation of the turntable 15, the air valve 51 is turned on by the valve cam 52 only in the section where the rotation table 16 needs to be rotated. When the air valve 51 is turned on, the air clutch 22 is switched to the connected state. When the air clutch 22 is thus connected, the rotation of the spindle gear 19 is transmitted to the rotary shaft 18 of the rotary table 16. Therefore, the rotary table 16 is rotationally driven (rotated) in the counterclockwise direction in FIG.
[0051]
Further, when the rotary table 16 is stopped before rotating, the container presser 32 is lowered, and the container presser body 34 of the container presser 32 is brought into contact with the mouth portion 6 of the container 1 on the rotary table 16. Then, the rotary table 16 is rotationally driven in a state where the mouth portion 6 of the container 1 is pressed from above by the container pressing body 34. At this time, the rotary table 16 has the handle 1 on the rotary table 16 along the container receiver 16a so that the stopper 45 always contacts the handle portion 5 of the container 1 regardless of the position of the stopper 45 in the container 1. Driven by one or more rotations.
[0052]
Further, when the turntable 16 rotates, the stopper 45 slides along the outer peripheral circle of the outer peripheral surface of the non-circular portion of the container 1. At this time, after the stopper 45 slides along the outer circumference of the container body 4, the tip of the stopper 45 is located between the container body 4 and the handle part 5 in the section between the container body 4 and the handle part 5. It is inserted into the recess. Subsequently, when the rotary table 16 further rotates, the stopper 45 is engaged in a state where the front end portion of the stopper 45 abuts against the engaging portion 5 a on one side portion of the handle portion 5. The stopper 45 is not engaged in a state where it is in contact with a portion other than the locking portion 5a on one side of the handle portion 5, and the rotating state of the turntable 16 is continued.
[0053]
When the stopper 45 hits the locking portion 5a on one side of the handle portion 5 of the container 1, the rotation of the container 1 is stopped. At this time, since the air clutch 22 is connected, the rotary table 16 tries to rotate, but when the air clutch 22 slips, the rotary table 16 also stops. As a result, as shown in FIG. 6, the transmission of the rotational driving force of the rotary table 16 is blocked by the air clutch 22 when the stopper 45 hits the locking portion 5 a on one side of the handle portion 5 of the container 1. Then, when the orientation of the container 1 is matched with the predetermined posture control position direction set in advance, that is, when the stopper 45 hits the locking portion 5a on one side of the handle portion 5, Direction regulation ends.
[0054]
Further, after the air clutch 22 is disconnected and the rotary table 16 is stopped, the container presser 32 is raised, and at the same time, the grip wheel 8 is fed so that the direction of the handle portion 5 of the container 1 does not go out of order, and is conveyed to the next process. . At this time, when the container 1 is delivered, the stopper 45 also escapes from the movement track of the container 1, so that the container 1 can be delivered to the gripping wheel 8 without interfering with the stopper 45.
[0055]
Furthermore, the container 1 in which the orientation of the handle portion 5 is aligned is fed into the capping device 2 while the direction of the handle portion 5 is maintained by the grip type wheel 8. Then, after the cap direction is regulated by the capping device 2, the cap is pushed into the container 1.
[0056]
Thereafter, the container 1 whose cap has been finished is fed out to the feeding line 11 for feeding by the star wheel of the feeding device 12 or the like. Further, the cap is inspected on the star wheel of the feeding device 12, and the defective container 1 in which no cap, indentation failure, direction failure or the like is detected is defectively discharged to the defective product delivery line 13.
[0057]
Therefore, the above configuration has the following effects. That is, in the container attitude control device 7 according to the present embodiment, the container 1 is supported on the turntable 15 so as to be able to come into contact with and separate from the container 1 on the table 16, and when the container 1 is fed into the rotary table 16 from the feeding position. A stopper 45 is provided in contact with the outer peripheral surface of the non-circular portion, and when the rotary table 16 rotates, the stopper 45 is brought into contact with the locking portion 5a on one side of the handle portion 5 of the container 1 by the air clutch 22. By blocking the transmission of the rotational driving force of the rotary table 16, the orientation of the container 1 is set in a specific posture control position direction, that is, the position where the stopper 45 abuts against the locking portion 5a on one side of the handle portion 5. Can be adjusted to the direction. Therefore, the grip-type wheel from the steering position in a state in which the orientation of the handle portion 5 of the container 1 with a handle in which a non-circular portion such as the handle portion 5 is formed on the outer peripheral surface is aligned with a specific setting direction. 8 can accurately carry out the work to be transferred to the next process in a short time.
[0058]
Further, in the present embodiment, the stopper main body 48 is detachably attached to the swing member 47 by the screw member 50, so that the replacement of the stopper main body 48 at the time of mold change is facilitated. Furthermore, the stopper body 48 can be easily removed from the swing member 47 when using a container that does not require direction regulation, such as a container other than the container 1 with handle. Therefore, the container 1 can be used in many types of containers other than products having similar shapes.
[0059]
Furthermore, since the container 1 with the orientation of the handle portion 5 aligned can be fed into the capping device 2 while the direction of the handle portion 5 is maintained by the grip type wheel 8, a large-capacity container such as edible oil or soy sauce Thus, operations such as aligning the direction of the cap spout and the handle portion 5 in the container 1 with a handle can be easily performed.
[0060]
In the present embodiment, the air clutch 22 is used as the clutch mechanism for interrupting transmission of the rotational driving force of the turntable 16, but the same effect can be obtained even if a mechanical clutch mechanism is used. As the clutch mechanism, an electromagnetic clutch or the like may be used as long as the same action can be obtained. Further, the rotary drive unit that rotates the rotary table 16 may have other configurations such as a motor and an air actuator as long as the same action can be obtained.
[0061]

In addition, a corresponding shape portion 64 a having a shape corresponding to the locking portion 5 a formed by one side portion of the handle portion 5 is formed at the contact portion of the distal end portion of the stopper main body 64 with the container 1.
[0067]
Next, the operation of the present embodiment having the above configuration will be described. FIGS. 11A to 11E show the operating state of the stopper 61 during rotation of the turntable 16 during driving of the container attitude control device 7 according to the present embodiment. FIG. 11A shows that the tip of the stopper main body 64 of the stopper 61 is placed on the rotary table 16 when the container 1 fed into the entrance of the attitude control device 7 from the feeding position is received by the container receiver 16a. The state inserted in the recessed part between the handle part 5 of the container 1 and the container main body 4 is shown. At this time, the stopper main body 64 of the stopper 61 is urged by the spring force of the tension spring 65 in the direction of turning clockwise in FIG. Therefore, the distal end portion of the stopper main body 64 is held in a state of being in contact with the outer peripheral surface of the container main body 4. In addition, in the position of FIG. 11 (A), pressure angle (theta) 1 when the front-end | tip part of the stopper main body 64 is contact | abutted with the outer peripheral surface of the container main body 4 is set small.
[0068]
Further, during the rotation of the turntable 15, the turntable 16 is driven to rotate in the counterclockwise direction in FIG. 11A only in a necessary section as in the first embodiment. When the turntable 16 is rotated, the stopper 61 is moved from the position shown in FIG. 11A to the position shown in FIG. 11B and then moved onto the outer peripheral surface of the container 1 at the position shown in FIG.

Therefore, in the present embodiment, a horizontal rocking lever type stopper main body 64 fixed to a rocking member 63 rotatably supported around a rocking shaft 62 extending in a substantially vertical direction is provided for rotation. When the stopper 61 abuts against the locking portion 5a on one side of the handle portion 5 of the container 1 when the table 16 is rotated, the transmission of the rotational driving force of the rotary table 16 is cut off by the air clutch 22 so that the container 1 The direction can be adjusted to a specific posture control position direction set in advance, that is, a position direction in which the stopper 61 abuts against the engaging portion 5a on one side of the handle portion 5. Therefore, also in this embodiment, as in the first embodiment, the orientation of the handle portion 5 of the handle-equipped container 1 in which the non-circular portion such as the handle portion 5 is formed on the outer peripheral surface is set to a specific setting direction. The operation of carrying the sheet from the steering position to the next process by the grip type wheel 8 in a state where the directions are aligned and the direction is adjusted can be accurately performed in a short time.
[0072]
12 and 13 show a third embodiment of the present invention. This embodiment is provided with a stopper 81 having a configuration different from the stopper 45 in the container attitude control device 7 of the first embodiment (see FIGS. 1 to 8). The other parts have the same configuration as the container attitude control device 7 of the first embodiment, and the same parts as those of the container attitude control device 7 of the first embodiment are denoted by the same reference numerals. A description thereof will be omitted here.
[0073]
That is, as shown in FIGS. 12 and 13, the stopper 81 according to the present embodiment is a horizontally swinging lever type stopper body supported so as to be rotatable about a swinging shaft 82 extending in a substantially vertical direction. 83 is provided.
[0074]
Here, the swing shaft 82 of the stopper 81 protrudes upward on the upper surface side of the stopper support base 84 as shown in FIG. Further, a bearing member 85 of a swing shaft 82 is mounted on the stopper support base 84, and the swing shaft 82 is pivotally supported by the bearing member 85.

A stopper bolt 89 for restricting the swing range of the stopper main body 83 is provided on the stopper bolt mounting base 88 so as to project on the swing track of the stopper main body 83.
[0077]
Further, the stopper bolt mounting base 88 is provided with a second spring receiving portion 90 bent in a substantially L shape. A tension spring 91 is installed between the first spring receiving portion 87 of the stopper main body 83 and the second spring receiving portion 90 of the stopper bolt mounting base 88.
[0078]
Moreover, as shown in FIG. 12, the container 1 with a handle used in the present embodiment has a handle portion 5 of the container 1 larger than the outer diameter of the outer peripheral surface of the container body 4, and the handle portion 5 of the container 1 is the container body. 4 is formed by a convex container with a handle protruding outside the outer peripheral surface.
[0079]
Next, the operation of the present embodiment having the above configuration will be described. When the container attitude control device 7 of the present embodiment is driven, the container 1 fed into the entrance of the attitude control device 7 is placed on the rotary table 16 and can be rotated around the rotation axis 18 around the axis. Supported by At this time, the directions of the handle portion 5 of the container 1 are different. Further, at the same time when the container 1 is fed, the tip of the stopper body 83 of the stopper 81 is brought into contact with the outer peripheral surface of the container 1 on the table 16.
[0080]
When the rotary table 16 is stopped before the rotation, the container presser 32 is lowered, and the container presser body 34 of the container presser 32 is brought into contact with the mouth portion 6 of the container 1 on the rotary table 16. As a result, the mouth portion 6 of the container 1 is pressed from above. In this state, the rotary table 16 is driven to rotate. At this time, the rotary table 16 is such that the front end portion of the stopper main body 83 of the stopper 81 contacts the handle portion 5 of the container 1 no matter where the front end portion of the stopper main body 83 of the stopper 81 is located.

[0081]
Further, when the turntable 16 is rotated, the tip end portion of the stopper body 83 of the stopper 81 slides along the outer circumference of the outer circumferential surface of the non-circular portion of the container 1. At this time, after the distal end portion of the stopper main body 83 of the stopper 81 slides along the outer peripheral circle of the container main body 4, the distal end portion of the stopper main body 83 of the stopper 81 is the handle portion 5 as shown in FIGS. 12 and 13. It is engaged in a state where it abuts against the locking portion 5a on one side. Note that the tip end portion of the stopper body 83 of the stopper 81 is not engaged when in contact with a portion other than the locking portion 5a on one side of the handle portion 5, and the rotating state of the turntable 16 is continued.
[0082]
Further, when the tip of the stopper main body 83 of the stopper 81 hits the locking portion 5a on one side of the handle portion 5 of the container 1, the rotation of the container 1 is stopped. As a result, the state in which the orientation of the container 1 is adjusted to the preset specific posture control position direction, that is, the tip end portion of the stopper main body 83 of the stopper 81 is one side portion of the handle portion 5 as in the first embodiment. At the time when it comes into contact with the locking portion 5a, the direction regulation of the container 1 is finished by the ratchet action.
[0083]
Therefore, in the present embodiment, a horizontal swing lever type stopper main body 83 supported so as to be rotatable about a swing shaft 82 extending in a substantially vertical direction is provided. The direction of the container 1 is determined by blocking the transmission of the rotational driving force of the rotary table 16 by the air clutch 22 when the front end of the stopper body 83 abuts against the engaging part 5a on one side of the handle part 5 of the container 1. Can be set in a specific posture control position direction set in advance, that is, a position direction in which the distal end portion of the stopper main body 83 of the stopper 81 abuts against the engaging portion 5a on one side portion of the handle portion 5. Therefore, also in this embodiment, as in the first embodiment, the orientation of the handle portion 5 of the handle-equipped container 1 in which the non-circular portion such as the handle portion 5 is formed on the outer peripheral surface is set to a specific setting direction. The operation of carrying the sheet from the steering position to the next process by the grip type wheel 8 in a state where the directions are aligned and the direction is adjusted can be accurately performed in a short time.
[0084]
Furthermore, in this embodiment, as shown in FIG. 12, the handle portion 5 of the container 1 is larger than the outer diameter of the outer peripheral surface of the container main body 4, and the handle portion 5 of the container 1 protrudes outside the outer peripheral surface of the container main body 4. Even the convex type container with a handle has an effect that the direction of the direction can be reliably controlled by the stopper body 83 of the horizontal swing lever type stopper 81.

The rotation of 1 stops. Then, when the orientation of the container 1 is matched with the predetermined posture control position direction set in advance, that is, when the stopper 45 hits the locking portion 5a on one side of the handle portion 5, Direction regulation ends. Thereafter, the outer peripheral surface of the container 1 is moved to the delivery position with the grip type wheel 8 while sliding along the friction member 102 of the container guide member 101. Then, the grip type wheel 8 is fed so that the direction of the handle portion 5 of the container 1 does not go out of order, and is conveyed to the next process.
[0091]
Therefore, the above configuration has the following effects. That is, in this embodiment, the container 1 held by each container receiver 16a is pressed against the friction member 102 of the container guide member 101 by the rotation support rollers 103a and 103b of each container receiver 16a, and the turntable 15 is shown in FIG. When the container 1 is rotated (revolved) in the clockwise direction as indicated by the arrow, the container 1 is rotated counterclockwise by the frictional resistance of the contact portion between the outer peripheral surface of the container 1 and the friction member 102 of the container guide member 101. It is designed to rotate (rotate) one or more times. Then, the friction resistance of the contact portion between the outer peripheral surface of the container 1 and the friction member 102 of the container guide member 101 in a state where the tip end portion of the stopper 45 abuts against the locking portion 5a on one side of the handle portion 5. By overcoming and stopping the rotation of the container 1, the direction of the container 1 is adjusted to a predetermined posture control position direction, that is, a position direction in which the stopper 45 hits the locking portion 5 a on one side of the handle portion 5. be able to. Therefore, also in this embodiment, as in the first embodiment, the orientation of the handle portion 5 of the handle-equipped container 1 in which the non-circular portion such as the handle portion 5 is formed on the outer peripheral surface is set to a specific setting direction. The operation of carrying the sheet from the steering position to the next process by the grip type wheel 8 in a state where the directions are aligned and the direction is adjusted can be accurately performed in a short time.
[0092]

[0096]
And in this Embodiment, the container 1 currently hold | maintained by the star wheel etc. of the feeding apparatus 10 is pressed against the belt 111 with the rotation support rollers 103a and 103b. Therefore, by driving the belt 111, the container 1 can be rotated (rotated) one or more times in the clockwise direction in FIG.
[0097]
Further, when the container 1 rotates on the star wheel or the like of the feeding device 10, the stopper 45 slides along the outer peripheral circle of the outer peripheral surface of the non-circular portion of the container 1 as in the first embodiment. Then, the stopper 45 is engaged in a state where the front end portion of the stopper 45 abuts against the engaging portion 5 a on one side of the handle portion 5. The stopper 45 is not engaged in a state where it is in contact with a portion other than the locking portion 5a on one side of the handle portion 5, and the rotating state of the turntable 16 is continued.
[0098]
