Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a working apparatus for continuously carrying out various operations such as airtightness inspection, liquid injection or tapping on an upright moving body such as a bottle container which is continuously transferred by a conveyor. Regarding

[0002]

2. Description of the Related Art A plurality of bottles that are continuously transferred are collectively held on an intermittent rotary table, and a fan-shaped plate having a filling nozzle corresponding to the bottles is moved up and down around a rotary table. After completing filling while pivotally supporting as much as possible and engaging with the rotary table via the rod when the fan-shaped plates descend, the fan-shaped plate is lifted to release the engagement of the rods. At the same time, a filling device is known in which a fan-shaped plate is returned to its original position by a return spring (Japanese Patent Publication No. 59-46874). The above-mentioned conventional device is accompanied by a vertical movement of the fan-shaped plate, so that vibration and impact are large, and in addition, the fan-shaped plate itself must be lifted together with a plurality of filling nozzles, and thus a large lifting force generator is required. Further, since the engagement and disengagement of the fan-shaped plate and the rotary table are performed by the engagement rod integrated with the fan-shaped plate, the rotary table on the drive side must be temporarily stopped and engaged and disengaged, so that the rotary table is necessarily intermittently rotated. I had to.

[0003]

SUMMARY OF THE INVENTION The present invention provides a quiet and highly efficient device by ameliorating these drawbacks.
In particular, the fan-shaped swivel plate and its rotation support shaft are not moved up and down but only horizontally rotated, and the engagement between the rotation table and the support shaft is smoothly performed by the ratchet mechanism provided on the gear that rotates in synchronization with the rotation table. It is something to do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 1 is a container rotating device, 10 is a supporting cylinder vertically fixed on a machine frame base plate 11, 12 is rotatably provided on the outer periphery of the supporting cylinder, and is provided with a boss 14. A container holding frame 13 is fixedly installed on the periphery of the table. 15
Is a first gear fixed to the lower surface of the turntable and drives the turntable. Reference numeral 2 denotes a swivel plate rotation return device, and 20 denotes a swivel support shaft penetrating the concentric shaft of the support cylinder 10 and vertically supported so as to be rotatable, and has a fan-shaped swivel plate 22 at its upper end. It is pivoted. A jig or a mounting head 26 for supporting the working device 3 such as a liquid filling nozzle, an air blowing nozzle for leak inspection or a tapping tool by a cylinder 25 or the like so as to be able to move up and down is provided on the outer circumferential arc portion 24 of the swivel plate. . Reference numeral 28 denotes a bearing that supports and holds the support shaft in the support cylinder. 30 is
It is a second gear that is the same as the first gear 15, and is rotatably fitted to the support shaft and is supported by a collar 32 that is axially attached to the support shaft via a thrust bearing 31.
Reference numeral 35 is a ratchet wheel located on the upper surface side of the second gear 30 and pivotally attached to the support shaft by key connection, and 37 is one notch step portion provided on the outer peripheral edge 36 of the wheel. 40
Is an engaging claw and has a pin 42 on the outer peripheral surface of the upper surface of the second gear.
It has a spring 43 which is pivotally attached by means of which the tip portion 41 is constantly urged against the outer peripheral surface of the ratchet wheel. Engaging claw 4
0 corresponds to a unit work angle of the swivel plate, and four pieces are provided at 90 ° angular intervals, for example. Reference numeral 44 denotes a rear end portion of the engaging claw, which projects to the outside of the second gear in the illustrated apparatus. Reference numeral 46 denotes an abutment pin fixed to the mechanism, which disengages the tip 41 of the engaging claw from the notch 37 of the wheel when abutting against the rear end 44 of the engaging claw. Reference numeral 50 is a rotation return means of the support shaft, and 52 is a coil spring provided at the lower end of the shaft.
The returning means is arbitrary, and can be realized by the lever 55 and the air cylinder 56 which are pivotally attached to the support shaft. By using the cylinder 56 and the spring 52 together and using the cylinder 56 as a shock absorber, the inertia during intermittent rotation and the shock during return from rotation can be mitigated. Reference numeral 60 is a drive device that rotates continuously or intermittently in one direction, and 63 is a drive shaft that stands upright in parallel with the support shaft 20. 66 is mounted on the shaft and drives the first gear 15 and the second gear 30, respectively.

[0006]

The containers transferred from a conveyor (not shown) are sequentially aligned and held on the turntable 12 in an upright state. The number of holding frames 13 is 24, and the first and second gears 15,
30 and the number of teeth of the first and second pinions 65 and 66 is 4: 1
Then, every one sixth rotation of the drive shaft 63, one holding frame is rotated, that is, at a pitch of 15 °. When processing containers in units of six, the unit working angle of the swivel plate is 90 °, so the engaging claws 40 are provided in units of 90 °. The intermittent rotation of the drive shaft 63 causes the first and second pinions 65 and 66 to rotate the first and second gears 15 and 30, respectively, in the same direction. Second
One of the engaging claws 40 on the gear engages with the notch step portion 37 of the ratchet wheel to rotate the support shaft 20 via the wheel 35, so that the fan-shaped swivel plate 22 rotates in synchronization with the rotary base 12. However, during this rotation, each working device 3 performs a predetermined work on the containers located immediately below or simultaneously or separately. When the rear end portion 44 of the engaging claw engaged with the notch step portion of the ratchet wheel contacts the contact pin 46, the tip 41 of the engaging claw is disengaged from the notch 37 as shown in FIG. Since it is released from the engaged state, the support shaft 20 is retained by the stored force of the return spring 52.
And the ratchet wheel 35 reverses in the direction of arrow B. As a result, the swivel plate 22 is returned to the original position, and the notch step portion 37 of the ratchet wheel is engaged with the subsequent engagement claw 40 to prevent reverse rotation, and the forward rotation is continued again by the turning force of the second gear 30. It is rotated in the direction of arrow A. When the drive shaft 63 is continuously rotating, the same operation as described above can be performed by adjusting the working time of the working device 3 and the return operation timing of the swivel plate.

[0007]

According to the device of the present invention, there is no vertical movement of the swivel plate on which the working device is mounted and the supporting shaft supporting the swivel table, regardless of whether the rotary table rotates continuously or intermittently. It can provide various working environment. In addition, the desired working position and rotation angle can be easily set by setting the position of the ratchet wheel, the engaging claws and the contact pin, and the synchronous rotation of the swivel plate and the original position return timing are accurately set.
Can be maintained.
