Description

Technical Field

[0001] This utility model relates to the field of filling line technology, and in particular to an automated collaborative conveying device for cups and caps during the filling process. Background Technology

[0002] A filling line is an automated production line used in the production process to fill liquids, powders or other materials into containers (such as cups). Filling lines are widely used in many industries such as food, beverages, pharmaceuticals, and cosmetics, and are an indispensable part of modern manufacturing. In a filling line, after the cups are transported to the filling unit and filled, they need to be sealed to ensure that the material does not leak. Sealing methods include screw capping, pressure capping, heat sealing, and cold sealing.

[0003] In existing filling lines, the conveyor line first transports cups to the filling unit, and after filling, it transports them to the next station, where they wait for manual or capping mechanisms to place the caps on the cups. Then, the capping mechanism locks them in place. This process suffers from the problem of asynchronous transport of cups and caps, leading to production interruptions or defective products. Secondly, the lack of an automatic rejection function requires manual intervention to handle defective caps, increasing labor intensity and production costs. Therefore, we propose an automated collaborative conveying device for cups and caps during the filling process to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose an automated collaborative conveying device for cups and caps in the filling process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated collaborative conveying device for cups and caps during the filling process includes a conveyor line one and a conveyor line two, as well as a turntable one and a turntable two. A rotating shaft is fixedly connected to the bottom center of each of the turntables one and two. Multiple semi-circular slots are provided on the outer side of each of the turntables one and two. A detection mechanism, a recycling mechanism, and a material replenishment mechanism are provided on the outer side of the turntable two.

[0007] The detection mechanism includes a photoelectric camera, which is used to capture detailed images of the cover; the feeding mechanism includes a third conveyor line and a pusher cylinder, which is used to push the cover on the third conveyor line into the second turntable.

[0008] In a preferred embodiment, turntable one and turntable two are arranged symmetrically from left to right, with turntable two positioned above turntable one. The rightmost semicircular notch of turntable one and the leftmost semicircular notch of turntable two are located on the same vertical line, and the positions of the rightmost semicircular notch of turntable one and the leftmost semicircular notch of turntable two are set as overlapping areas.

[0009] In a preferred embodiment, a retaining ring two is provided on the outer side of the turntable two, and a movable section is provided on the retaining ring two. The output end of the push cylinder is fixedly connected to the movable section, and the conveyor line three is provided on one side of the movable section.

[0010] In a preferred embodiment, the first turntable and the second turntable are slidably connected by the same sector ring. The top of the sector ring has a rectangular opening, and a rotating plate is rotatably mounted on one side of the inner wall of the rectangular opening via a hinge. A driving mechanism is provided at the bottom of the sector ring, which is used to drive the rotating plate to swing downward. The recovery mechanism is located below the rotating plate.

[0011] In a preferred embodiment, the first conveyor line includes two sub-lines, with a U-shaped ring fixedly connected to the same side of the two sub-lines. The first conveyor line is used to convey the cup body into the first turntable and receive the cup lid assembly sent out by the first turntable. The U-shaped ring is used to support the cup body that follows the first turntable in a circular motion.

[0012] In a preferred embodiment, a retaining ring is fixedly installed above the U-shaped ring. The inner wall of the retaining ring is set with a sloping arc surface. The retaining ring is used to limit the cup body.

[0013] In a preferred embodiment, the detection mechanism further includes an analysis system and a transmitter. Receivers are provided on both the feeding mechanism and the driving mechanism. The analysis system controls the start and stop of the feeding mechanism and the driving mechanism through the cooperation of the transmitter and the receiver.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By driving two rotating shafts to rotate in opposite directions at the same frequency, turntable one rotates clockwise and turntable two rotates counterclockwise. The semi-circular bayonets on turntable one and turntable two overlap in the overlapping area, realizing the connection between the cup body and the lid body. This achieves synchronous delivery of the cup body and the lid body, ensuring the consistency of time and space between the two, precise matching, and avoiding production interruptions or quality problems caused by asynchrony.

[0016] 2. The system captures detailed images of the lid using a photoelectric camera, analyzes the images, and controls the feeding mechanism and drive mechanism to start based on the analysis results. This enables the recycling of defective lids and the feeding of the semi-circular opening of empty lids. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 An automated collaborative conveying device for cups and caps during the filling process includes a conveyor line 1 and a conveyor line 2, as well as a turntable 3 and a turntable 4. A rotating shaft 15 is fixedly connected to the bottom center of both the turntable 3 and the turntable 4. Multiple semi-circular slots 5 are provided on the outer side of both the turntable 3 and the turntable 4. A detection mechanism, a recycling mechanism and a material replenishment mechanism are provided on the outer side of the turntable 4.

[0026] The detection mechanism includes a photoelectric camera 6, which is used to capture detailed images of the cover; the feeding mechanism includes a conveyor line 10 and a push cylinder 7, which is used to push the cover on the conveyor line 10 into the turntable 4.

[0027] It should be noted that the detection method for the cap in this embodiment can also be applied to the detection of the cup. The reason for setting up the detection of the cap is that even if the cap has cracks or dimensional deviations that result in poor sealing of the cup, the cup is always facing upwards on the filling line, and the leakage is not easy to be detected. Therefore, the necessity of detecting the cap is much greater than that of the cup, which can save equipment costs.

[0028] like Figure 1 As shown, turntable 3 and turntable 4 are arranged symmetrically from left to right. Turntable 4 is located above turntable 3. The rightmost semicircular notch 5 of turntable 3 and the leftmost semicircular notch 5 of turntable 4 are located on the same vertical line. The positions of the rightmost semicircular notch 5 of turntable 3 and the leftmost semicircular notch 5 of turntable 4 are set as the overlapping area 16.

[0029] like Figure 2 and Figure 3 As shown, a retaining ring 2 8 is provided on the outer side of the turntable 2 4, and a movable section 9 is provided on the retaining ring 2 8. The output end of the push cylinder 7 is fixedly connected to the movable section 9. The conveyor line 3 10 is located on one side of the movable section 9. Initially, the movable section 9 coincides with the retaining ring 2 8, serving as a limiting mechanism for the cap. The caps transported by the conveyor line 3 10 are all photoelectrically detected. Because the conveyor line 3 10 is used to replace caps, it is stationary most of the time, allowing sufficient time for detection without affecting the cycle time of the filling line.

[0030] like Figure 4 and Figure 5 As shown, a sector ring 11 is slidably connected between turntable 3 and turntable 4. A rectangular opening 17 is provided at the top of the sector ring 11. A rotating plate 12 is mounted on one side of the inner wall of the rectangular opening 17 via a hinge. A drive mechanism is provided at the bottom of the sector ring 11. The drive mechanism is used to drive the rotating plate 12 to swing downward. A recovery mechanism is provided below the rotating plate 12.

[0031] like Figure 4 and Figure 5 As shown, conveyor line one includes two sub-lines, with a U-shaped ring 13 fixedly connected to the same side of both sub-lines. Conveyor line one is used to convey the cup body into turntable one 3 and receive the cup lid assembly sent out by turntable one 3. The U-shaped ring 13 is used to support the cup body as it follows the turntable one 3 in circular motion. In this utility model, a retaining ring one 14 is fixedly installed above the U-shaped ring one 13. The inner wall of retaining ring one 14 is set with a sloping arc surface. Retaining ring one 14 is used to limit the cup body. The sloping arc surface on retaining ring one 14 can better fit the cup body at a certain angle, providing support and limiting the movement of the cup body.

[0032] In this embodiment, the detection mechanism also includes an analysis system and a transmitter. Receivers are provided on both the feeding mechanism and the drive mechanism. The analysis system controls the start and stop of the feeding mechanism and the drive mechanism through the cooperation of the transmitter and the receiver.

[0033] It should be noted that the photoelectric camera 6 is a CCD camera. The CCD camera can capture detailed images of the cover, and then analyze the images through a dedicated software algorithm to detect whether there are defects in the cover. This detection process is non-contact and can be completed quickly and accurately, meeting the high-speed detection requirements in large-scale production environments. The analysis system controls the start and stop of the feeding mechanism and the drive mechanism based on the detection results. The main moving parts of the feeding mechanism are the conveyor line 3 10 and the push cylinder. The conveyor line 3 10 is driven by a servo motor. The drive mechanism includes an electric push rod and a connecting rod, which are rotatably connected to the electric push rod and the rotating plate 12, respectively.

[0034] The working principle of this utility model is as follows: the rotating motor drives two rotating shafts 15 to rotate in opposite directions at the same frequency through the gear differential, thereby driving turntable 3 to rotate clockwise and turntable 4 to rotate counterclockwise. The semi-circular bayonet 5 on turntable 3 and turntable 4 overlap in the overlapping area 16, realizing the connection between the cup body and the lid body in the overlapping area 16, and then the conveyor line 1 and conveyor line 2 are started synchronously.

[0035] Conveyor line two transports the cover into the semi-circular slot 5 on turntable two 4. For ease of description, the position of the rightmost semi-circular slot 5 on turntable two 4 is designated as position one, the position of the semi-circular slot 5 above the turntable 12 is designated as position two, and the position of the last semi-circular slot 5 on turntable two 4 is designated as position three. Turntable two 4, through the cooperation of the semi-circular slot 5, retaining ring two 8, and fan-shaped ring 11, drives the cover to perform a circular motion. When the cover moves to position one, the photoelectric camera 6 captures a detailed image of the cover. The analysis system analyzes the image. If the cover has defects, such as cracks, dimensional deviations, or irregular shapes, etc., it is classified as follows: The analysis system controls the feeding mechanism and drive mechanism to start through the cooperation of the transmitter and receiver. First, the drive mechanism drives the rotating plate 12 to swing downward. The cover continues to move to position two and will fall into the recycling mechanism along the inclined rotating plate 12. At this time, the cylinder pushes the moving section 9 to move backward, releasing the obstruction of the conveyor line 10. The conveyor line 10 transports the qualified cover to the front of the moving section 9. The semi-circular slot 5 of the empty cover moves from position two to position three, pushing the cylinder to drive the moving section 9 and the new cover forward, so that the new cover is put into the empty semi-circular slot 5, realizing the function of replacing the unqualified cover.

[0036] The left sub-line of conveyor line 1 transports the cup into the semi-circular bayonet 5 on turntable 3. Turntable 3 drives the cup to move in a circular motion through the cooperation of the semi-circular bayonet 5, retaining ring 14 and U-shaped ring 13. During this process, the filling mechanism fills the cup. After the cup is filled, it moves to the overlapping area 16. At the same time, the qualified cap or the replaced cap continues to move from position 3 to the overlapping area 16. Since it loses the support of the fan-shaped ring 11, the cap falls into the cup, realizing the assembly function of the cap and the cup. Afterwards, the right sub-line of conveyor line 1 transports the assembled cap and cup to the next station for subsequent processing.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
