Abstract

PROBLEM TO BE SOLVED: To minimize the failure of the device and vessel by providing a control device by which the command of the operation stop of a filling device and the warning thereof is carried out on the basis of the phase difference between the detection signal of a first approach switch and that of a second approach switch. SOLUTION: While a first approach switch (a first KS) 71 detects the passage of the detection piece 62b that has been provided to the lower part of a star hub 62 and sends out an ON signal, in its normal operating condition, it synchronizes with the ON signal of the reference from the second KS of the synchronizing device in the same phase. When nonconformity is caused in the engagement or the like of a bottle 51, a driving shaft cylinder 64 continues rotation relatively with regard to the star hub 62 to which a star wheel 61 has been fixed, and becomes in a racing condition. Since the deviation in the phase of the cylinder 64 with regard to the ON signal of the reference from the second KS is caused, deviated time between both phases is compared with a control device, and when the time difference exceeds a given value, it is judged that nonconformity is caused, and the operation of the filling device is stopped, and warning is given to the workers. As a result, the damage in the parts can be reduced.

2. Description of the Related Art A conventional star wheel device has a structure as shown in a vertical sectional view of FIG. 7 and a plan view of FIG. Here, the star wheel 3 is made of synthetic resin or the like, and 12 recessed curved arc-shaped recessed pocket portions 3a adapted to the diameter of the bottle are provided around the outer peripheral portion thereof at equal pitches. The star hub that attaches the star wheel 3 to the star wheel drive shaft 11 is an inner star hub 21 that forms a central part.
The outer star hub 22 is divided and assembled into an outer star hub 22 that forms an outer peripheral portion of the outer star hub 22. The outer star hub 22 is coaxially rotatably mounted on the lower end flange portion 25 of the inner star hub 21. The inner star hub 21 has a plurality of bolts 6
Is fixed to the upper end flange of the star wheel drive shaft 11, and the vertical star wheel drive shaft 11 is rotatably supported by a vertical bearing 7. The star wheel drive shaft 11 is rotated by the rotation of a bottling machine (not shown),
The inner star hub 21 fixed to the star wheel drive shaft 11 by the bolt 6 is rotated. The outer staring surface of the inner star hub 21 is provided with four ball insertion holes 21a in the radial direction indicated by broken lines at four locations. On the other hand, on the inner peripheral surface of the outer star hub 22, a radial ball plunger 24 is provided at a position corresponding to each ball fitting hole 21a. The ball plunger 24 is screwed into the outer star hub 22, and the inner star hub 21 is screwed depending on the screwing amount.
The pressing force with respect to the ball fitting hole 21a can be adjusted. The circumferential arrangement distribution of these four ball plungers 24 and the ball fitting holes 21a is such that when the inner star hub 21 and the outer star hub 22 are relatively rotated once, they are fitted at only one position. They are arranged at unequal pitches. A pair of upper and lower parallel star wheels 3 having pockets 3a on the outer periphery are fixed to the outer star hub 22 at the inner periphery by a plurality of bolts 8. In the star wheel device having such a configuration, the star wheel drive shaft is rotated by the rotation of the bottling machine, and the inner star hub 21, the outer star hub 22, and the star wheel 3 are also rotated. Containers such as bottles, which are supplied to the pocket portions 3a of the star wheel 3 as the star wheel 3 rotates, are held in the pocket portions 3a in an upright posture and publicly transferred. At that time, an accident such as a bad bottle supply state or a bite of the bottle or an overturned bottle occurs, and an abnormal load is applied to the star wheel 3. At that time, if an abnormal load exceeds a preset pressing force of the ball plunger 24 against the ball fitting hole 21a, the ball plunger 24 is disengaged from the ball fitting hole 21, and the star wheel 3 idles to rotate the star wheel 3 or the like. It is designed to prevent bottle damage. To restore the star wheel 3 in the idling state and set it to the normal state, all the ball plungers 24 are fitted into the ball fitting holes 21a by rotating the star wheel 3 at most once. It is possible to return to the relevant position.

In such an apparatus, as shown in FIGS. 1 and 2, a driving shaft cylinder 64, a ball plunger 63, a star hub 62 and a star wheel 61 which are integrally connected through a cycloid gear 67 by the operation of the filling device 54. Rotates. At that time, the bottles 51 supplied to the star wheel device 60 are indexed at equal intervals by the indexing screw 52, delivered to the pocket portion 61a of the star wheel 61, guided by the guide 53, and transferred. Here, as shown in FIGS. 2 and 4, the first proximity switch 71 detects the passage of the detection piece 62b provided on the lower portion of the star hub 62, and as shown in FIG. But
In a normal operating state, the second proximity switch 57 of the synchronizer
It is in phase with the reference ON signal from (FIG. 5). Now, when the bottle supply state to the star wheel device 60 is poor and a problem such as biting of the bottle 51 occurs, a force for stopping the rotation acts on the star wheel 61, and the star wheel 61 and the drive shaft cylinder 64 continue to rotate. The working tangential force increases. When this tangential force exceeds the set value, the ball of the ball plunger 63 and the fitting hole 64a are disengaged, and the drive shaft cylinder 64 continues to rotate relative to the star hub 62 to which the star wheel 61 is fixed. It becomes idle. At this time, the first
The ON signal output from the proximity switch 71 (FIGS. 2 and 4) is delayed from the second proximity switch 57 (FIG. 5) as shown in FIG. Since a phase shift occurs with respect to the reference ON signal of (2), the time when the phases of both are shifted (hatched portion in FIG. 6B) is compared by a controller (not shown), and this time difference is a constant value. If it exceeds, it is judged that a problem has occurred and the operation of the filling device is stopped, an alarm is issued and the worker is notified. The set value of the tangential force at which the engagement between the star hub 62 and the drive shaft cylinder 64 is released is adjusted by the screwing amount of the ball plunger 63, and the disengaged ball plunger 63 and the ball fitting hole 64a are The drive shaft cylinder 64 can be re-engaged and restored to the normal state while the drive shaft cylinder 64 makes one rotation at the maximum.

In short, according to the present invention, a horizontal star wheel in which a plurality of semicircular pockets are recessed at equal intervals on the outer peripheral portion, and fixed at regular intervals along the outer periphery of the star wheel. In the star wheel device of the filling device that transfers the container while guiding the side of the container such as a bottle with the arc-shaped guide, the center hole of the star wheel is attached to the upper part, and a plurality of ball plungers are radially attached to the body. And a coaxial star hub each having the same number of detection pieces as the above-mentioned pockets in the lower part, and a ball plunger on the outer peripheral surface of the body part that is coaxially rotatably externally inserted through a bearing on a vertical center fixed shaft. A drive shaft cylinder having a plurality of ball fitting holes at opposite positions, the upper part of which is fitted in the center hole of the star hub to rotatably support the star hub, and the star hub. First to detect the passage of the detection unit
A proximity switch, a detection plate that rotates in synchronization with the drive shaft cylinder and has the same number of detection units as the pockets, a second proximity switch that detects passage of a detection piece of the detection plate, the first proximity switch, When a trouble such as biting of a container such as a bottle occurs due to the provision of a control device that stops the operation of the filling device and issues an alarm based on the phase difference between the detection signals of the second proximity switch, A safe and economical star wheel device that reduces the size of the overload on the device side, promptly detects abnormalities, stops the operation, alerts the workers, and minimizes damage to the device or container. Therefore, the present invention is extremely useful industrially.
