Description

Automatic bottle arranging device for plastic bottles

Technical Field

The invention relates to an automatic plastic bottle arranging device suitable for arranging plastic bottles on a packaging production line.

Background

An automatic unscrambler is one of the necessary devices in a packaging line to unscramble bottles as much as possible into an upright position. It is known that when the bottles are put on the production line, the posture is usually messy, and the requirements of the packaging production line on the posture of the bottles cannot be met. In the embodiment of the invention, the automatic bottle arranging device for the plastic bottle production line is suitable for arranging plastic bottles with bottle necks, and realizes automatic arrangement of the plastic bottles by utilizing the property of impact resistance and the property of inversion stability of the plastic bottles.

An automatic bottle unscrambler belongs to front-end equipment of an automatic packaging production line, and the quality and efficiency of unscrambling bottles influence the subsequent production efficiency and production quality. The automatic bottle arranging machine has the basic function of automatically arranging the plastic bottles in the plastic bags into an upright state and continuously conveying the plastic bottles to a production line. The traditional bottled water distributor is used by a plurality of manufacturers, and the traditional bottled water distributor mostly adopts a turntable with a relatively simple structure. The carousel adopts the state of putting flatly at present, hardly accomplishes the carding of plastic bottle, often needs the relatively complicated bottle tilting mechanism of reconfiguration structure for this reason, leads to reason bottle inefficiency, and adaptability is poor. Meanwhile, because the plastic bottles are in a conveying state, the plastic bottles are relatively difficult to capture by the bottle turnover mechanism, and therefore the rotating speed of the rotating disc needs to be reduced so as to reduce the difficulty of capturing the bottles by the bottle turnover mechanism. In view of the need for a bottle unscrambler that automatically recognizes bottles in an inverted position, it is inevitable that an additional recognition device is required, further increasing the complexity of the unscrambler.

In view of the complex overall structure of the current automatic bottle arranging device for plastic bottles and the problem of capturing bottles in a circulation state, the overall yield of a production line is low, the adaptability is poor, the reliability is poor (the whole is complex, the links are many), especially, the current automatic bottle arranging device is mostly specially designed for plastic bottles with specific shapes, and the adaptability to the shapes of the bottles is relatively poor.

In addition, for example, the national drug administration has made GMP certification requirements for all pharmaceutical companies nationwide. If the enterprise wants to produce the medicine, the enterprise must obtain the verification certification of the medicine quality management, and when the medical equipment certification fails and the medical company cannot pass the GMP certification, the medical company does not have the qualification of producing the product. However, many pharmaceutical companies, such as Asahi pharmaceutical companies and Vigorean pharmaceutical companies, require a bottle collator that is capable of distinguishing GMP certified flat bottles. There are more first generation reason bottle machine in the current market, the reason bottle speed of this kind of reason bottle machine is slow to degree of automation is low, needs artifical supplementary reason bottle, and it is inaccurate if the plastic bottle catches, needs artifical supplementary upset plastic bottle, and not only inefficiency may have life safety risk moreover. Due to the problems of the first bottle unscrambler, the popularization and application of the bottle unscrambler also have difficulties.

As is known, in order to satisfy the requirement of people for drinking, the mouth of a plastic bottle is relatively small, while in order to satisfy the requirement of relatively large containing capacity, the body is relatively large, and a bottleneck is required to be transited between the mouth and the body, so that when the plastic bottle is in a positive state, the stability of the plastic bottle is relatively good due to the large supporting area, and when the plastic bottle is in an inverted state, the stability of the plastic bottle is relatively poor due to the small supporting area. In the embodiment of the invention, the characteristic of the plastic bottle is fully utilized, an inclined turntable is adopted, the included angle between the axis of the turntable and the horizontal plane is correspondingly 60-80 degrees, the turntable is required to restrict the height of the plastic bottle, the height is not too small, the plastic bottle is not easy to be too large, the plastic bottle is not easy to be clamped in when the turntable is too large, and the plastic bottle is easy to topple even if the plastic bottle is rightly arranged, therefore, the tooth grooves are set to restrict the height of the plastic bottle to be less than the length of the bottleneck of the plastic bottle and to be more than or equal to 5 cm.

Detailed Description

The basic features of the plastic bottle 17 have been explained above, and since the individual weights are not so great when the plastic bottle is empty, the collision with each other is not sufficient to damage the plastic bottle.

The stability of the plastic bottle 17 in the upright (upright) state and in the inverted (inverted) state has been described in principle in the above description, and will not be described again here.

The basic shape of the body of the present plastic bottle 17 is a cylindrical or right quadrangular shape, which is easily restrained by the tooth grooves 19 as shown in fig. 2.

Meanwhile, the bottle body part is relatively heavy and is easy to be placed downwards or with the large end facing downwards under the action of rolling envelope. During rolling, the tooth grooves 19 are engaged, so that a standing position is easily obtained, or the number of plastic bottles 17 in the tooth grooves 19 is relatively small in an inverted position.

In addition, the distance from the bottle opening to the bottle body of the plastic bottle 17 is different from 3.5cm (short neck bottle) to 12cm (long neck bottle), in the embodiment of the invention, the restraint height of the fluted disc, namely the tooth socket 19 on the turntable 7 is suitable for the plastic bottle 17 with a relatively larger bottle neck, and a numerical range is restrained, specifically, the tooth socket 19 on the fluted disc is used for being clamped into the bottle body, and the tooth socket 19 restrains the height of the plastic bottle 17 to be less than the length of the bottle neck of the plastic bottle 17 and more than or equal to 5 cm; when the rotating disk 7 is relatively thin, if the rotating speed of the rotating disk 7 is relatively high, the plastic bottles 17 are easy to fall from the tooth grooves 19 even if the plastic bottles 17 are in the right position.

Referring to the description, the automatic bottle arranging device for plastic bottles shown in the attached fig. 1 and 2 has a basic structure comprising a bottle arranging bin 11, a main shaft 3, a rotary table 7, a first driving mechanism for driving the rotary table 7 to rotate, and a conveying chain 16 for assisting the integration of the automatic bottle arranging device into a production line.

The bottle arranging bin 11 must be easy to load firstly, so that the upper part of the bin is an open hopper chamber, which is basically a hopper structure, so that the bottles can be easily loaded from the upper part, if a large number of the plastic bottles 17 are loaded in the bottle arranging bin 11, mutual interference easily generates a supporting effect, and the bottles are not favorably clamped to the tooth grooves 19, so that a special loading mechanism is also arranged in a preferred embodiment to control the loading speed.

The bottle arranging bin 11 is provided with a circular enclosing shell, the circular enclosing shell forms the lower part of the hopper chamber, the included angle between the axis of the circular enclosing shell and the horizontal plane is 60-80 degrees, namely, the circular enclosing shell is in an inclined state, and a bottle outlet is formed in the side face of the highest position of the circular enclosing shell to be connected with the conveying chain 16 as seen from the left part of fig. 2.

In addition, as for the circular enclosure, a gap is left between the circular enclosure and the turntable 7, and this gap serves as a gap for avoiding interference of movement, and theoretically, the smaller the gap is, the better the gap is.

The turntable 7 is attached to the spindle 3, the spindle 3 may be a fixed shaft or a rotating shaft, and the turntable 7 and the spindle 3 may be rotatably or fixedly connected to each other. In any form of assembly between the turntable 7 and the spindle 3, the turntable 7 is required to have a degree of freedom of rotation, here rotation about the axis of the spindle 3.

And the rotating disc 7 is a toothed disc, the toothed grooves 19 on the toothed disc are used for clamping the plastic bottles 17 and carrying the plastic bottles 17 to rotate, for example, in a state that the plastic bottles 17 are inverted, because the bottle mouths are in a supporting state, even if part of the bottle bodies of the plastic bottles 17 are restrained by the toothed grooves 19 at the moment, the plastic bottles 17 are still easy to fall out of the toothed grooves 19, and especially when the plastic bottles 17 run to the highest position, because the toothed grooves 19 are relatively long (measured in the radial direction of the rotating disc 7), the plastic bottles 17 are very easy to fall out of the toothed grooves 19 in the inverted state.

Based on the above principle, the inverted plastic bottle 17 can be automatically removed without adding a bottle body turning mechanism. And as can be seen from the foregoing description, the number of plastic bottles 17 rejected per revolution is not large, since the body is more easily engaged in the gullets 19.

Meanwhile, for the production line, the requirement of the rotating speed of the corresponding rotating disc 7 is not large, and relatively large centrifugal force cannot be generated.

Correspondingly, the main shaft 3 is arranged in the center of the circular enclosure and is coaxial with the circular enclosure.

For the conveyor line, a conveyor chain 16, as shown in fig. 2, is mounted at the bottle outlet for guiding out and conveying out the plastic bottles.

In some embodiments, a bottle discharging dial wheel may be independently configured for the conveying line, and the bottle discharging dial wheel belongs to a conventional configuration on a bottled liquid packaging production line, and is not described herein again.

In other embodiments, a purely mechanical construction may be used for the out-of-bottle treatment. As shown in fig. 2, if a baffle is arranged on one side of the rotating disc 7 during the rotation process, the baffle is arranged on the upper side of the rotating disc 7 and forms a part of a chord on the upper surface of the rotating disc 7, the part is not more than half of the chord, when the plastic bottle 17 runs to the part, the plastic bottle is gradually pushed out from the tooth groove 19 by the baffle, and the baffle is referred to as a guide-out plate 18 in fig. 2.

The guide-out plate 18 may also form part of a flap on both sides of the conveyor chain 16 in order to smoothly guide the plastic bottles 17 into the conveyor chain 16.

In addition, as for the turntable 7, which has a degree of freedom of rotation, a driving mechanism is required to drive the rotation thereof, and for this purpose, a first driving mechanism is provided for driving the turntable 7 to rotate. Rotation is the most common form of motion in the mechanical field and, for example, an electric motor, the basic motion of which is a rotation, may be transmitted to the turntable 7 using a gear train.

Preferably, the angle between the axis of the circular enclosure and the horizontal plane is 75 degrees, which is a better structural parameter determined by experiments, and the inverted plastic bottle 17 can be rejected without the inverted plastic bottle 17 falling out.

In order to reduce the abrasion of the plastic bottles 17 carried by the rotary table 7 in the rotating process, an annular slide way is arranged at the projection position of a sweeping ring where the tooth grooves 19 on the rotary table 7 are located on the bottom surface of the bottle bin 11; the sweep ring can also be understood as the motion track of the toothed groove 19, which corresponds to the annular part of the bottom of the plastic bottle 17, which is in contact with the bottle arranging bin 11, so that the abrasion to the plastic bottle 17 is reduced, and the influence on the aesthetic property of the plastic bottle 17 is reduced.

Furthermore, the annular slide way is provided with the polytetrafluoroethylene or modified polytetrafluoroethylene annular slide plate, and the polytetrafluoroethylene or modified polytetrafluoroethylene annular slide plate still has a relatively small friction coefficient under the condition of not coating a lubricant.

In order to reduce the weight of the turntable 7, in some embodiments, the turntable 7 is configured to be lightweight, i.e., assembled from a plurality of disks having a certain span. Specifically, the turntable 7 comprises the following structures:

an upper tray body;

the lower disc body is arranged in parallel with the upper disc body and determines the thickness of the rotary disc, a certain distance is reserved between the upper disc body and the lower disc body, the distance depends on the constraint height, the thicknesses of the upper disc body and the lower disc body can be relatively small, and when the upper disc body and the lower disc body are manufactured by steel plates, the steel plates can still have relatively high rigidity even if the thicknesses of the steel plates are relatively small.

After assembly, the assembly formed by the upper tray body and the lower tray body is required to have the constraint height.

Furthermore, a hub is provided for the connection between the upper and lower discs and for the assembly of the turntable 7 on the spindle 3.

In a preferred embodiment, the turntable 7 is mounted on said spindle 3 by means of bearings, i.e. the turntable 7 is rotatable with respect to the spindle 3.

Correspondingly, a large gear 6 is arranged on the hub of the rotary table 7; the lower end of the main shaft 3 is also provided with a small gear 4, the small gear 4 and the large gear 6 rotate oppositely, or the main shaft 3 is not a static shaft, and the main shaft 3 is also arranged on the frame 1 through a bearing.

It will be appreciated that the sizes of the bull gear 6 and the pinion gear 4 are a pair of opposing concepts, and in general, for gear drives, the bull gear 6 tends to attain a relatively low rotational speed and the pinion gear 4 tends to attain a relatively high rotational speed, wherein the bull gear 6 is used to drive the turntable 7 at a relatively slow speed and the pinion gear 4 is used to drive the dial 8 at a relatively high speed.

Furthermore, a dial 8 is fixedly connected to the upper end of the main shaft 3, the dial 8 is parallel to the rotary table 7, the dial 8 is mainly located on the rotary table 7, and the plastic bottles which are embedded in the tooth grooves 19 are swept down, so that when the rotary table 7 rotates at a slow speed, the plastic bottles 17 are secondarily dropped into a lower position of the bottle arranging bin 11.

As regards the dial 8, it may comprise a hub and spokes mounted in spoke fashion on the hub.

The following is a description of a first drive mechanism comprising a duplicate gear 10, one gear of the duplicate gear 10 meshing with the gearwheel 6 and the other gear meshing with the pinion 4 via an idler 5 to obtain different steering.

Correspondingly, the first driving mechanism further comprises a motor reducer assembly 2, and an output shaft of the motor reducer assembly 2 is connected with a gear shaft of the duplicate gear 10 through a coupler.

The motor reducer assembly 2 is a configuration of a common small-capacity motor at present, a reducer is configured for the motor reducer assembly when the motor reducer assembly leaves a factory, an all-in-one machine of the motor reducer is formed, and reliability and adaptability are relatively good.

In some embodiments, the tooth grooves 19 are U-shaped grooves, and the central axis of the U-shaped grooves is a radial line of the rotating disc 7, which is relatively good in adaptability to the bottle shape and easy to lead out by the lead-out plate 18, for example.

Preferably, the depth of the U-shaped groove in the radial direction of the rotating disc 7 is 1.5-2 times of the width of the U-shaped groove.

In the foregoing, it is pointed out that, in order to ensure the relative uniformity of the feeding speed of the carousel 7, in some embodiments, a specific feeding device is also provided, which comprises:

a feed hopper 15 for loading plastic bottles 17, which can be loaded in batches into the plastic bottles 17;

a conveyor extending to the lower part of the feeding hopper 15 or connected with the mouth of the feeding hopper 15 and further extending upward to a predetermined height to match the height of the bottle arranging bin 11;

and the discharge hopper 12 is used for receiving the upper end of the conveyor and guiding the plastic bottles 17 into the bottle arranging bin 11.

In a preferred embodiment, the conveyor is a screw conveyor, which facilitates a high conveying accuracy.
