When the bottle conveying device is used, a plurality of multi-bottle-mouth compatible bottle conveying devices are usually arranged according to the conveying distance in the filling production process. In the following, two multi-bottleneck compatible bottle transfer devices are specifically used as an example, and for convenience of description, the multi-bottleneck compatible bottle transfer device is simply referred to as a bottle transfer device. As shown in fig. 5, two adjacent first bottle conveying devices 100 and second bottle conveying devices 200 are provided, wherein the first bottle conveying device 100 is engaged with the filling machine, and the second bottle conveying device 200 is output outwards. The first bottle transfer device 100 has two types of first and

second bottle holders

5 and 6 mounted therein. The second bottle transfer device 200 is provided with a third bottle gripper 5 'and a fourth bottle gripper 6' of two gripping types. The clamping calibers of the first bottle clamp 5 and the third bottle clamp 5' are the same and belong to the same clamping type, so that the first bottle clamp and the third bottle clamp are matched for use. The clamping calibers of the second bottle clamp 6 and the fourth bottle clamp 6' are the same, and belong to the same clamping type, so that the bottle clamps are matched for use.

When the mouth caliber of the bottle output by the filling machine is matched with the first bottle clamp 5, the first bottle clamp 5 is adopted for bottle transmission. The adjustment is driven by the servomotor 3 so that each bottle delivered by the filling machine is exactly received by one first bottle gripper 5 in the first bottle conveyor 100, while the adjustment is driven by the servomotor in the second bottle conveyor 200 so that each time a bottle delivered by the first bottle gripper 5 in the first bottle conveyor 100 is exactly received by one third bottle gripper 5' in the second bottle conveyor 200. When the bottle mouth of the bottle outputted by the filling machine is matched with the second bottle clamp 6 and the fourth bottle clamp 6 ', the bottle mouth is adjusted to use the second bottle clamp 6 and the fourth bottle clamp 6' according to the process. The adjustment is very convenient, and the bottle clamp is prevented from being frequently replaced, so that the manpower and material resources are saved, the time is effectively saved, and the production efficiency is greatly improved.

In addition, the top or the below of the clamping piece 11 on each bottle clamp is provided with a stop block 17, and the stop block 17 is arranged to play the following roles: the stop block 17 is abutted to the outer wall of the bottle opening, so that the bottle is kept in a vertical downward state in the conveying process and is not prone to skewing, the bottle can be smoothly transferred, accidents such as bottle falling, bottle clamping, bottle scratching and the like cannot happen, the bottle conveying efficiency is effectively improved, and the filling production quality is improved.

The setting method of the stopper 17 is specifically as follows: in the two adjacent bottle transfer devices, the first bottle gripper 5 and the third bottle gripper 5' of the first bottle transfer device 100 and the second bottle transfer device 200 transfer the bottles to each other, for example. If the stop in the first bottle gripper 5 of the first bottle transfer device 100 is above the jaws, then the stop in the third bottle gripper 5' of the second bottle transfer device 200 is below the jaws. That is, in two adjacent bottle conveying devices, the stopper on the bottle clamp in one bottle conveying device is above the clamping piece, and the stopper in the bottle clamp of the same clamping type in the other bottle conveying device is located from the clamping piece to the bottom. Like this, first bottle presss from both sides 5 and third bottle presss from both sides 5 ' when handing-over transmission, the clamping piece centre gripping of first bottle clamp 5 is in the bottom of support ring on the bottleneck, the dog that first bottle pressed from both sides 5 keeps off the top of leaning on at the bottleneck support ring, the clamping piece of third bottle clamp 5 ' then the centre gripping is at the top of the support ring of bottleneck, the dog that third bottle pressed from both sides 5 ' then keeps off the bottom of the support ring of leaning on at the bottleneck, this bottle keeps vertical decurrent state when effectively guaranteeing the handing-over transmission, thereby take place to fall the bottle when avoiding the bottle transmission, the fish tail bottleneck, phenomenons such as bottle extrusion take place, and then effectively improved bottle conveying efficiency, and effectively improved filling production quality.
