Description

Full-automatic bottle cap screwing device

Technical Field

The utility model relates to the technical field of liquid dressing filling, in particular to a full-automatic bottle cap screwing device.

Background

The liquid dressing is a liquid with disinfection effect, can directly act on pathogens, and has inhibitory effect on most bacteria, viruses and protozoa. When the liquid dressing is sprayed on the wound surface of a wound, a layer of protective film can be formed to protect the wound, and meanwhile, the wound is isolated from the outside, so that the invasion of outside germs is avoided, and meanwhile, the liquid dressing has a killing effect on germs around the wound. In the production of liquid dressing and in the subpackage packaging, filling equipment is generally used, and the filling equipment is used for filling the liquid dressing into packaging bottles. The packaging bottle consists of a bottle body and a bottle cap. During filling, the liquid dressing is filled into the bottle body through the filling opening, the filling is stopped after the set filling amount is reached, and then the bottle cap is pressed and fixed or fixed on the filling opening in a spinning mode, so that the bottle cap and the filling opening are combined into a whole, and the filling and packaging treatment of the packaging bottle is completed.

In the actual filling operation, the bottle body is transferred through the conveyor, filling is completed when the bottle body passes through the position right below the filling equipment, the bottle body continuously moves backwards, the bottle cap is placed in place relative to the bottle body through workers or a bottle cap feeding device, the bottle body continuously moves, the bottle cap is reliably buckled and pressed on the bottle body under the action of a bottle cap screwing device, filling and packaging of the liquid dressing are completed, and the liquid dressing is stored in a warehouse and delivered after labeling. When the bottle body is communicated with the bottle cap and is transferred to the position under the bottle cap screwing device, the bottle cap screwing device moves to drive the screwing pressure plate to move downwards until the bottle cap is completely pressed against the bottle cap, then the screwing pressure plate performs circumferential rotation movement under the action of rotation torque, and the bottle cap is screwed on the bottle body under the action of friction force. However, there are the following problems in actually performing the bottle cap screwing operation: 1) during the process of screwing the bottle cap, the bottle body is bound to be acted by external rotation torque, and particularly, along with the advance of the tightening process, the rotation torque value borne by the bottle body is synchronously increased. When the friction force generated by the bottom surface is not enough to resist the rotating torque, the bottle body is inevitably rotated, the final tightness of the bottle cap relative to the bottle body is influenced, the subsequent liquid dressing leakage phenomenon is caused, and the overall tightening efficiency of the bottle cap is reduced to a certain extent; 2) when the pre-screwing packaging bottle has larger contraposition deviation relative to the screwing pressure plate, the packaging bottle is easy to topple due to unbalanced downward pressure, and the subsequent screwing process cannot be normally carried out. Thus, a skilled person is urgently needed to solve the above problems.

SUMMERY OF THE UTILITY MODEL

Therefore, in view of the above-mentioned problems and drawbacks, the present invention provides a method for automatically applying a bottle cap to a bottle cap, which comprises collecting relevant information, evaluating and considering the relevant information, and performing experiments and modifications by a skilled person engaged in the industry.

In order to solve the technical problem, the utility model relates to a full-automatic bottle cap screwing device which comprises a rack, a sliding plate, an upper linear driving element and a screwing functional part. The frame crosses the conveyer, and it includes the roof and inserts N stands that match on the roof perpendicularly. The sliding plate is used for bearing the twisting function part, is arranged in parallel under the top plate and performs displacement motion along the vertical direction under the action of the upper linear driving element. The screwing function part comprises a screwing pressure plate and a rotary driving part. The rotary driving part is fixed on the top wall of the sliding plate. The screwing platen is used for directly screwing the bottle cap, is arranged in parallel just below the sliding plate, and can freely perform circumferential rotation motion around the central axis thereof under the action of the rotation driving part. In addition, the full-automatic bottle cap screwing device further comprises a clamping unit. The clamping unit comprises a front clamping sub-unit and a rear clamping sub-unit. The front clamping sub-unit and the rear clamping sub-unit are respectively arranged at the front side and the rear side of the screwing station in a one-to-one correspondence manner. When the bottle body and the bottle cap are stopped in place relative to the screwing station, the front clamping sub-unit and the rear clamping sub-unit act simultaneously to apply lateral ejection force to the side wall of the bottle body.

As a further improvement of the technical scheme of the utility model, the design structures of the front clamping sub-unit and the rear clamping sub-unit are consistent. For the front clamping sub-unit, it includes a front support seat, a front linear driving element and a front push plate. The front supporting seat is detachably fixed on the front side wall of the conveyor and is used for supporting and jacking the front linear driving element. The front push top plate is just corresponding to the screwing station for placement. When the front linear driving element is started, the front pushing plate moves towards or away from the bottle body so as to lock or unlock the relative position of the bottle body.

As a further improvement of the technical scheme of the utility model, a pushing notch is arranged on the rear side wall of the front pushing plate. Assuming that the outer diameter of the bottle body is d1, and the diameter of the pushing notch is d2, the diameter is more than 0 d2-d1 and less than or equal to 0.2 mm.

As a further improvement of the technical scheme of the utility model, when the bottle body is a glass bottle, the front push top plate is preferably a hard plastic plate; and when the bottle body is a plastic bottle, the front push top plate is preferably an elastic rubber plate.

As a further improvement of the technical scheme of the utility model, the upper linear driving element and the front linear driving element are both preferably cylinders; and the rotation driving part is preferably a reduction motor.

As a further improvement of the technical scheme of the utility model, the full-automatic bottle cap screwing device also comprises a guide assembly. The guide assembly is composed of N sliding sleeves. The sliding sleeves are all embedded on the sliding plate and are sleeved on the stand columns in a one-to-one correspondence manner and in a freely sliding manner along the up-down direction.

As a further improvement of the technical scheme of the utility model, the screwing functional part also comprises an elastic rubber pad. The elastic rubber pad is attached to the bottom wall of the screwing pressure plate, and the thickness of the elastic rubber pad is controlled to be 1-1.5 mm.

As a further improvement of the technical scheme of the utility model, the screwing functional part also comprises a cylindrical spring. The columnar spring is used for applying elastic downward force to the screwing pressure plate and sleeved on a power output shaft of the rotary driving part.

Compared with the full-automatic bottle cap screwing device with the traditional design structure, the technical scheme disclosed by the utility model is additionally provided with the clamping unit. When the bottle body and the bottle cap are parked in place relative to the screwing station, the front clamping sub-unit and the rear clamping sub-unit belonging to the clamping unit act simultaneously to apply lateral ejection force to the side wall of the bottle body, and the friction force triggered by ejection contact is used for resisting the rotation torque generated in the subsequent bottle cap screwing process, so that the problem of 'follow-up rotation' of the bottle body in the screwing process is avoided, and the bottle cap is ensured to have good tightness relative to the bottle body.

In addition, because the bottle body is simultaneously acted by the front clamping sub-unit and the rear clamping sub-unit, even if a larger alignment deviation occurs between the screwing pressure plate and the bottle body, the standing stability of the bottle body can be effectively ensured, and the phenomenon of toppling over caused by the action of unbalanced downward pressure is avoided.

Detailed Description

In the description of the present invention, it is to be understood that the terms "front", "rear", "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The utility model will be described in further detail with reference to an embodiment in which a fully automatic cap screwing device is associated with a filling line, which is arranged downstream of a cap feeder, as shown in fig. 1. When the bottle caps are placed in position relative to the bottle bodies and conveyed to the bottle cap screwing station under the conveying force of the conveyor, the full-automatic bottle cap screwing device acts to apply a rotating torque to the bottle caps until the bottle caps are reliably tightened on the bottle bodies.

Fig. 2 is a perspective view showing the fully automatic bottle cap screwing device according to the present invention, which is mainly composed of a frame 1, a slide plate 2, an upper cylinder 3, a screwing function part 4, and a clamping unit 5. Wherein, frame 1 strides across the conveyer, and it includes roof 11, stand 12, bottom plate 13 and supporting leg 4. The bottom plate 13 is arranged in parallel right below the top plate 11, and the two are connected and fixed by 4 pieces of upright posts 12. The legs 4 are vertically inserted into the base plate 13 and are fixed to the floor of the workshop by anchor bolts (as shown in fig. 3). The slide plate 2 is used to support the screwing function portion 4, which is arranged in parallel directly below the top plate 11 and performs displacement motion in the up-down direction by the action of the built-in cylinder 3. The screwing function portion 4 includes a screwing pressure plate 41 and a reduction motor 42 (shown in fig. 4). The reduction motor 42 is fixed to the top wall of the slide plate 2. The screwing platen 41 is used to screw the caps directly, is arranged in parallel directly below the slide 2 and is free to perform a circumferential rotation movement about its central axis under the action of a reduction motor 42. When the bottle cap screwing operation is executed, the upper air cylinder 3 is started, the screwing pressure plate 41 moves downwards synchronously along with the sliding plate 2 until the screwing pressure plate is contacted with the bottle cap, then the speed reducing motor 42 is started, the screwing pressure plate 41 continuously executes circumferential rotation motion around the central axis of the screwing pressure plate under the action of rotation torque, and meanwhile, the upper air cylinder 3 continues to push the sliding plate 2 to move downwards for a small distance until the bottle cap is completely screwed on the bottle body. It should be emphasized here that the clamping unit 5 includes a front clamping sub-unit 51 and a rear clamping sub-unit 52. The front clamping sub-unit 51 and the rear clamping sub-unit 52 are respectively arranged at the front side and the rear side of the screwing station in a one-to-one correspondence manner.

When the bottle body and the bottle cap are stopped in place relative to the screwing station, the front clamping sub-unit 51 and the rear clamping sub-unit 52 belonging to the clamping unit 5 act simultaneously to apply lateral ejection force to the side wall of the bottle body, and the friction force triggered by ejection contact is used for resisting the rotation torque generated in the subsequent bottle cap screwing process, so that the problem of 'follow-up' of the bottle body in the screwing process is avoided, and the bottle cap is ensured to have good tightness relative to the bottle body.

In addition, because the bottle body is simultaneously acted by the front clamping sub-unit 51 and the rear clamping sub-unit 52, even if a large alignment deviation occurs between the screwing pressure plate and the bottle body, the stability of the bottle body standing can be effectively ensured, and the phenomenon of toppling over caused by the action of unbalanced downward pressure is avoided.

It is known that the front clamping sub-unit 51 can adopt various design structures to realize the propping or clamping of the bottle body, but a design structure with simple design structure, easy implementation and high propping stability is recommended here, which is as follows: as shown in fig. 7, the front clamping sub-unit 51 is mainly composed of a front support base 511, a front cylinder 512, and a front pushing plate 513. The front support base 511 is detachably fixed on the front side wall of the conveyor, and is used for supporting the front cylinder 512. The front ejector plate 513 is placed right opposite to the screwing station. When the preposed air cylinder 512 is started, the preposed top pushing plate 513 carries out displacement movement towards/away from the bottle body so as to realize/release the locking of the relative position of the bottle body.

The rear clamping subunit 52 can be designed in a similar way to the front clamping subunit 51.

Furthermore, as shown in fig. 7, a pushing notch 5131 is formed on the rear side wall of the front pushing plate 513. When the bottle body and the cap are stopped in place with respect to the screwing station, the front clamping sub-unit 51 moves to perform a displacement motion with respect to the bottle body until the bottle body is completely inserted into the pushing notch 5131. Similarly, the rear clamping sub-unit 52 has the same design structure. Therefore, on one hand, the contact area of the front clamping sub-unit 51 and the rear clamping sub-unit 52 is ensured to be as large as possible when the front clamping sub-unit and the rear clamping sub-unit are in top contact with the bottle body, and larger circumferential friction force is favorably triggered; on the other hand, the bottle body is clamped into the pushing notch 5131, which means that the freedom of displacement along the left and right directions is completely limited, thereby being beneficial to ensuring the stability and consistency of the self direction in the subsequent bottle cap screwing process and better avoiding the phenomenon of 'toppling over'.

In general, assuming that the outer diameter of the bottle body is d1 and the diameter of the pushing notch 5131 is d2, 0 < d2-d1 is 0.2mm, considering the smooth insertion of the bottle body into the pushing notch 5131 and the stability of the bottle body against or clamped.

In addition, it should be noted that, in order to further enhance the effect of the bottle body being pushed or clamped, in the actual design, the material of the front pushing plate 513 should be carefully selected. The front ejector plate 513 is preferably a rigid plastic plate, for example, when the pre-clamped bottle body is a glass bottle; when the pre-clamped bottle is a plastic bottle, the front pushing plate 513 is preferably an elastic rubber plate.

Furthermore, as shown in fig. 2, it can be seen that a guiding assembly 6 is further added to the fully automatic bottle cap screwing device to ensure that the sliding plate 2 has good guiding precision when the dragging screwing function portion 4 performs displacement movement, thereby ensuring that the screwing pressure plate 41 has high alignment precision relative to the pre-screwing bottle body. Specifically, the guide assembly 6 is composed of N sliding sleeves 61. The sliding sleeves 61 are all embedded on the sliding plate 2, and are sleeved on the upright post 12 in a one-to-one correspondence manner and in a manner of freely sliding along the up-down direction.

It is known that the specific magnitude of the screwing force that can be applied to the closure by the screwing platen 41 during the actual screwing operation is a critical factor that limits whether the closure is screwed. In view of this, as a further optimization of the structure of the screwing function part 4, an elastic rubber pad 43 is added. The elastic rubber pad 43 is attached to the bottom wall of the screwing platen 41, and its thickness is controlled to be 1-1.5 mm (as shown in fig. 4, 5, 6). Compared with the metal screwing pressure plate 41, the elastic rubber pad 43 has larger relative friction coefficient when acting on the bottle cap, which is beneficial to ensuring that the torque is reliably and stably applied to the bottle cap.

Since the bottle cap is easily deformed when subjected to a rigid squeezing force, as a further optimization of the structure of the screwing function part 4, as also shown in fig. 4, 5 and 6, a cylindrical spring 44 is further sleeved on the power output shaft of the reduction motor 42. The cylindrical spring 44 can exert a resilient pressing force on the pressing plate 41. Thus, the bottle cap is effectively prevented from being subjected to the action of rigidity force at the moment of contact with the screwing platen 41, the integrity and consistency of the appearance of the bottle cap are ensured, and good bedding is further achieved for reliable screwing with the bottle body. In addition, it should be clarified that, by adopting the above technical solution, the cylindrical spring 44 always applies an elastic downward pressure to the screwing pressure plate 41 when the screwing operation is performed, and the above elastic rubber pad 43 is combined to better ensure that the torque is reliably and stably applied to the bottle cap.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
