[0024] Reference Figure 1 to Figure 4 The automatic straightening device for an inverted bottle in an embodiment of the present invention comprises a conveying device 10, two straightening mechanisms and a guide plate mechanism for flipping the bottle mouth direction of the inverted bottle. The two straightening mechanisms are a first straightening mechanism 21 near the entrance of the conveying device 10 and a second straightening mechanism 22 near the exit of the conveying device 10. The guide plate mechanism is located between the two straightening mechanisms.

[0025] The conveying device 10 includes a conveyor belt driven by a motor. Guardrails 12 are provided on both sides of the transmission device 10. Specifically, the guardrails 12 are provided on both sides above the conveyor belt to prevent the bottles from falling and causing losses during the conveying process. The conveying device 10 is divided into two conveying channels by a partition 11. The partition 11 is provided along the conveying direction. The two conveying channels are a straightening channel and a non-straightening channel, respectively. The straightening mechanism and the guide plate mechanism are both located on the straightening channel. Preferably, the non-straightening channel is provided with guardrails 12 and partitions 11 on both sides, one side of the straightening channel is the partition 11, and a baffle 13 is provided between the other side of the straightening channel and the guardrail 12. The baffle 13 is provided along the conveying direction of the straightening channel. Furthermore, two inclined plates are provided at the entrance of the conveying device 10, one of which connects the inner side of the guardrail 12 and the end of the partition 11, and the other is connected to the end of the inner baffle 13 of the guardrail 12. The two inclined plates form a bucket-shaped conveying space, so that the bottles entering the conveying device 10 can enter the straightening channel one by one in an orderly manner through the conveying space to avoid mutual interference in the straightening channel.

[0026] A flow dividing mechanism is provided between the guide plate mechanism and one of the straightening mechanisms. Preferably, a flow dividing mechanism is provided between the guide plate mechanism and the first straightening mechanism 21. A flow dividing mechanism may also be provided between the entrance of the conveying device 10 and the first straightening mechanism 21. Figure 3 , the diverter mechanism includes a diverter plate 40 for blocking upright bottles, the diverter plate 40 is provided with a through hole for allowing inverted bottles to pass through, the partition 11 is provided with a notch, and the diverter plate 40 is obliquely connected to one side of the notch of the partition 11. Specifically, one end of the diverter plate 40 is connected to the baffle 13, and the other end of the diverter plate 40 is connected to the side of the notch of the partition 11 close to the end of the conveying direction, and the diverter plate 40 and the notch of the partition 11 together form a conveying port that can convey upright bottles to the non-straightening channel. Taking the diverter mechanism between the first straightening mechanism 21 and the conveying device 10 as an example, when the bottle is transported to the diverter plate 40 by the conveyor belt, the inverted bottle can continue to move along the straightening channel through the through hole on the diverter plate 40, while the upright bottle is blocked by the diverter plate 40 due to the height limit, and under the action of the continuous friction force of the conveyor belt, it passes through the notch on the partition 11 along the inclined direction of the diverter plate 40 and enters the non-straightening channel to prevent the upright bottle from affecting the straightening action of the inverted bottle in the straightening channel. In addition, considering the convenience of collecting bottles at the outlet of the conveyor 10, a diverter mechanism may be provided between the second straightening mechanism 22 and the outlet of the conveyor. During the conveying process, some bottles may not be straightened by the straightening mechanism due to different sizes, damage or mechanical errors of the equipment. Therefore, the upright bottles are diverted by the diverter mechanism to enter the non-straightening channel and finally discharged and collected from the outlet, while the bottles that have not been straightened continue to be conveyed along the straightening channel, without affecting the subsequent bottle conveying.

[0027] Each straightening mechanism is installed above the conveying device 10 through a bracket. Optionally, the bracket is installed horizontally above the conveying device 10, and the straightening mechanism includes a hook, which is hinged on the bracket through a mounting portion. In a natural state, the hook is vertically downward and the hook mouth faces the entrance of the conveying device 10. When an inverted bottle with the bottle mouth in the same direction as the conveying direction is transported to the straightening mechanism, the hook hooks the bottle mouth of the inverted bottle. As the conveyor belt exerts force on the inverted bottle, the inverted bottle and the hook rotate along the hinge point, so that the inverted bottle can stand upright. When the bottle mouth is upward, the hook still hooks the bottle mouth, causing the bottle to rotate backward at a certain angle, while causing the hook to detach from the bottle mouth, but the bottle will not fall over; when the hook detaches from the bottle mouth, the bottle swings forward under the action of gravity until it stands firmly as an upright bottle, and the hook returns to its original position under the action of gravity. When the inverted bottle with its mouth in the opposite direction to the conveying direction is transported to the straightening mechanism, the hook contacts the bottom of the inverted bottle and thus cannot reverse the inverted direction of the bottle, and the inverted bottle continues to move along the conveyor belt.

[0028] The baffle 13 is provided with an opening, see Figure 2 The guide plate mechanism includes two parallel first guide plates 31 and a second guide plate 32, wherein one first guide plate 31 is connected obliquely to the side of the opening of the baffle 13 close to the entrance of the conveying device 10, and the other first guide plate 31 is connected obliquely to the partition 11, and a guide channel is formed between the two first guide plates 31, and the second guide plate 32 is connected to the other side of the opening of the baffle 13, and the second guide plate 32 and the guide channel are arranged in a V shape. Preferably, the two ends of the second guide plate 32 are respectively connected to the opening of the baffle 13 and the inner side of the guardrail 12, and the second guide plate 32 includes a first group of plates 321 and a second group of plates 322 connected to each other, the first group of plates 321 is vertically connected to the inner side of the guardrail 12, and the angle between the second group of plates 322 and the conveying direction is an acute angle. The inverted bottle with the mouth direction opposite to the conveying direction moves along the straightening channel until it enters the guide channel between the two first guide plates 31. The inverted bottle moves along the guide channel at an angle, and then changes the angle of inclination under the friction of the conveyor belt and the blocking action of the first set of plates 321. Under the action of the force of the conveyor belt, the inverted bottle fits the second set of plates 322, and moves along the second set of plates 322 with the conveyor belt. The direction of the bottle mouth changes and it re-enters the straightening channel. The inverted bottle moves along a V-shaped track in the guide plate mechanism, so that the direction of the bottle mouth changes. The length of the first set of plates 321 is less than the height of the bottle, so as to avoid the inverted bottle being unable to move along the direction of the second set of plates 322 due to the blocking of the first set of plates 321.

[0029] As a further preferred embodiment, a first transition plate 51 is provided between the first straightening mechanism 21 and the entrance of the conveyor 10, and a second transition plate 52 is provided between the guide plate mechanism and the first straightening mechanism 21. The first transition plate 51 and the second transition plate 52 are both arranged above the conveyor 10. The working principle of the first transition plate 51 is the same as that of the second transition plate 52, and the first transition plate 51 is used as an example below. Optionally, the first transition plate 51 is made of a wear-resistant rough material, and both ends of the first transition plate 51 are fixed to the inner side of the guardrail 12. It is located above the conveyor belt and very close to the conveyor belt, but does not contact the conveyor belt, so that the bottle can transition from the conveyor belt to the first transition plate 51. When the bottle passes through the first transition plate 51, due to the large friction between the bottle and the first transition plate 51, the bottle is easily accumulated on the first transition plate 51. When the number of accumulated bottles reaches a certain amount, the bottle can transition from the first transition plate 51 to the conveyor belt. The function of the first transition plate 51 is to cause the bottles to pile up and decelerate when passing through the first transition plate 51, so that when transitioning to the conveyor belt, the distance between each bottle will be pulled apart to ensure that the subsequent bottle straightening work can be carried out independently without interference. Furthermore, the inlet of the conveyor 10 and the outlet of the non-straightening channel can be respectively provided with an inlet transition plate and an outlet transition plate to ensure the orderly entry and delivery of the bottles.

[0030] The operation process of the present invention is as follows: multiple bottles enter the straightening channel one by one, and the upright bottles enter the non-straightening channel through the notch of the partition 11 after the diversion of the diverter plate 40, and the inverted bottles continue to move along the conveyor belt in the straightening channel. When passing through the first straightening mechanism 21, the first straightening mechanism straightens the inverted bottles whose bottle mouth direction is the same as the conveying direction, and through the diversion of the diverter mechanism, the inverted bottles whose bottle mouth direction is opposite to the conveying direction continue to move in the straightening channel. Under the action of the conveyor belt, the first guide plate 31 and the second guide plate 32, the inverted bottles move in a V-shaped trajectory, so that the bottle mouth direction is reversed and enters the straightening channel again, and is straightened by the second straightening mechanism 22. The upright bottles after straightening enter the non-straightening channel through the diversion of the diverter mechanism, and are then collected; and individual inverted bottles that have not been straightened due to various reasons are discharged along the straightening channel.

These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
