Description

TECHNICAL AREA

[0001] The present utility model relates to the technical field of packaging equipment for food and pharmaceuticals, in particular to a separating device for rows of plastic containers. STATE OF THE ART

[0002] The all-in-one continuous blowing, filling, and sealing (BFS) machine is an efficient piece of pharmaceutical equipment. It can simultaneously extrude, form, fill, and seal medical-grade plastic particles such as polyethylene (PE) and polypropylene (PP) under aseptic conditions, offering the advantages of high production capacity, low energy consumption, easy maintenance, sterility, and a low waste rate. The all-in-one BFS machine allows the molten plastic tube embryo to be continuously formed, filled, and sealed without cutting, as in [unclear - possibly referring to a specific process or application]. Fig. Figure 1 shows the continuously formed row of bottles being transported via the conveyor belt to the stamping device, so that the plastic bottle body is separated from the waste after stamping.

[0003] Chinese patent document CN220389697U discloses a stamping device for rows of bottles. The positioning components of the bottle rows on the upper and lower dies are adjustable and slidable, as is the stamping head on the lifting bracket. Through the interaction of these two components, the device can adapt to the positioning and stamping of bottle rows with varying shrinkage rates, resulting in a good stamping effect and minimal burrs. The stamping surfaces of the stamping head are inclined towards the bottle heads of the row. During stamping, the stamping surface first makes contact with the bottle head, thus stamping out the more complex structure of the bottle head. The body and tail of the bottle are then stamped to complete the stamping effect.Compared to flat die-cutting, the contact area between the inclined die and the row of bottles is smaller, which reduces both the resistance and noise generated during the die-cutting process. However, as the width of the bottle row increases, multiple die-cutting heads must be mounted on the die holder. Since several die-cutting heads contact the bottle row simultaneously, the resistance and noise can increase significantly. Furthermore, the thin walls of the die are more prone to breakage, thus shortening its lifespan. CONTENTS OF THE PRESENT USE SAMPLE

[0024] The present utility model is explained in more detail below in conjunction with the drawings and specific embodiments of the description. Example I

[0025] Fig. 2 to Fig. Figure 4 shows an embodiment of a separating device for rows of plastic containers according to the present utility model. The separating device for rows of plastic containers according to the present embodiment comprises a punching arrangement 1, a punching drive part 2 (e.g., cylinder, electric push rod, etc.) for driving the raising and lowering of the punching arrangement 1, a lower clamping part 3, an upper clamping part 4, and a conveyor track 6, wherein a punching channel 41 for the passage of the punching arrangement 1 is arranged on the upper clamping part 4, wherein a first container discharge channel 31 is arranged on the lower clamping part 3, and wherein the punching arrangement 1 comprises a plurality of punching units 11 (In the present embodiment, a total of 3 punching units 11 are provided; of course, the number of punching units 11 can be further adjusted in other embodiments).(the container 71 is in particular designed as a bottle body), wherein the plurality of punching units 11 are arranged in the conveying direction of the conveyor 6, wherein the punching surfaces 12 of the at least two punching units 11 have different heights (since the height of the punching surfaces 12 is different, the distance to the upper end of the first container discharge channel 31 is also not the same, wherein the punching surface of the nearby punching unit 11 is punched first and the farther punching surface of the punching unit 11 is punched afterwards), wherein a buffer mechanism is arranged between the first container discharge channel 31 and the conveyor 6, wherein the buffer mechanism can support the containers obtained by punching the respective punching unit 11 in order to ensure that the containers obtained by punching the respective punching unit 11 can fall over the discharge channel and then simultaneously onto the conveyor 6.

[0026] The separating device for rows of plastic containers according to the present embodiment comprises several punching units 11, which is advantageous for improving punching efficiency. The height of the punching surfaces 12 of at least two punching units 11 differs, thus avoiding problems with high punching resistance and noise caused by punching all punching units 11 simultaneously. Due to the different heights of the punching surfaces 12 of the punching units 11, containers 71 fall successively. A buffering effect can be provided by the buffering mechanism. After all containers 71 have fallen onto the buffering mechanism, the buffering mechanism is opened again, so that the containers 71 fall simultaneously onto the conveyor 6.This avoids the problems of stacking and crushing caused by the successive falling of containers 71, resulting in a simple structure and good reliability.

[0027] In a preferred embodiment, it is provided that the distance of the punching surfaces 12 of the plurality of punching units 11 from the upper end of the first container discharge channel 31 gradually increases from one side to the other, with reference to in particular Fig. 3a and Fig. 3c, so that sequential punching from one side to the other can be realized by this construction, or wherein the at least two punching units 11 are arranged symmetrically, with reference to in particular Fig. 3d, so that this construction achieves symmetry and a good balance of forces, which is advantageous for improving the stability of the punching arrangement 1 during operation. Furthermore, it is provided that the upper clamping part 4 is provided with an upper fastening unit 42, wherein the lower clamping part 3 is provided with a lower fastening unit 32, with reference in particular to Fig. 3a and Fig. 6. The rows of plastic containers have waste edges. An upper fastening unit 42 and a lower fastening unit 32 are arranged opposite each other to grip and fasten the waste edge area of ​​the rows of plastic containers to be cut. The plastic containers are divided into independent rows for cutting. The plastic container units can be cut from the rows of plastic containers during punching by the respective punching units 11, which does not affect the fastening of the other plastic container units.

[0028] In the present embodiment, a release mechanism 5 is arranged below the lower clamping part 3, wherein the release mechanism 5 has a first deflection plate 51, with reference to in particular Fig. 2. The first deflection plate 51 can serve as a guide, which facilitates the falling of the container 71 onto the conveyor track 6. In the present embodiment, the buffer mechanism is provided to have a first buffer plate 53, which is flipped upwards and downwards, wherein the first buffer plate 53 can be aligned against the upper end of the first deflection plate 51, with reference in particular to Fig. 5c and Fig. 5d. The first buffer plate 53 is initially in a horizontal position, and the container 71 falls from the first container discharge channel 31 onto the first buffer plate 53. After all containers 71 have completely fallen onto the first buffer plate 53, the first buffer plate 53 is turned downwards to align with the upper end of the first deflection plate 51, so that the containers 71 are transferred to the first deflection plate 51 by gravity. Finally, the first buffer plate 53 is turned upwards for reset, a simple and reasonable design. Furthermore, an opening corresponding to the first divider plate 54 is provided on the first buffer plate 53. The first divider plate 54 can be passed through the opening in the first buffer plate 53 when the first buffer plate 53 is turned downwards.

[0029] In the present embodiment, a plurality of first separating plates 54 are arranged on the first deflection plate 51, wherein a second container drain channel 55 is formed between two adjacent first separating plates 54, wherein the plurality of punching units 11 is assigned to the plurality of second container drain channels 55 in a one-to-one correspondence, wherein a plurality of second separating plates 56 are arranged on the first deflection plate 51, wherein the plurality of second separating plates 56 is assigned to the plurality of first separating plates 54 in a one-to-one correspondence, with reference to in particular Fig. 4. The distance between the upper edge of the second separating plate 56 and the conveyor track 6 is greater than the length of the container. After the second separating plate 56 has been retracted to the first deflecting plate 51, a channel can be formed between the conveyor track 6 and the first deflecting plate for the movement of containers towards the conveyor track 6. The bottle bodies punched by the various punching units 11 are separated by the first separating plate 54 and the second separating plate 56, which is advantageous to prevent the bottle from tipping over and jamming during the downward movement of the bottle bodies, thus further improving reliability.

[0030] In the present embodiment, the buffer mechanism is provided to have a reciprocating second buffer plate 57, wherein the second buffer plate 57 is arranged in the area of ​​the first deflection plate 51 adjacent to the conveyor track 6, with reference to in particular Fig. 4a to Fig. 4c. The freely sliding bottle bodies may not all fall onto the conveyor 6 simultaneously, so there is a risk of bottle stacking and bottle jamming on the high-speed conveyor 6. The second buffer plate 57 provides a buffering effect. After all the bottle bodies have fallen onto the second buffer plate 57, the second buffer plate 57 moves so that the bottle bodies fall onto the conveyor 6 simultaneously, further improving reliability. Of course, in other embodiments, the buffering mechanism may also include only the second buffer plate 57 or only the first buffer plate 53.

[0031] In the present embodiment, the second buffer plate 57 acts synchronously with the second separating plate 56, so that a container drainage channel is formed between the first deflection plate 51 and the second deflection plate 52, with reference to in particular Fig. 4c. The container discharge channel between the first deflection plate 51 and the second deflection plate 52 can serve to form a support in the vertical direction to ensure that the container remains upright in the vertical direction after leaving the punching mechanism.

[0032] In the present embodiment, the second buffer plate 57 is a reciprocating plate and the direction of movement is perpendicular to the conveying direction of the conveyor track 6, with reference to in particular Fig. 5e and Fig. 5f. After all the bottle bodies have fallen onto the second buffer plate 57, the second buffer plate 57 moves to the side facing away from the conveyor 6, so that the bottle bodies fall onto the conveyor 6, resulting in a simple structure and requiring little space. Of course, in other embodiments, the second buffer plate 57 could also be an inverted structure or a telescopic structure, which are not repeated here.

[0033] In the present embodiment, a second deflection plate 52 is arranged on the side of the first deflection plate 51 facing away from the first container discharge channel 31 (the second deflection plate 52 is located in Fig. 2 to the right of the first deflection plate 51). The second deflection plate 52 works together with the first deflection plate 51, so that movement of the bottle body in the width direction of the conveyor track 6 can be limited, which facilitates the falling of the bottle body onto the conveyor track 6.

[0034] In the present embodiment, it is provided that the stamping surface 12 of the stamping arrangement 1 is designed at an angle, with reference in particular to Fig. 2. During the die-cutting process, the lower side of the die-cutting surface 12 is associated with the bottle neck of the bottle body. In the die-cutting process, the die-cutting surface 12 first comes into contact with the bottle neck, so that the bottle neck, with its more complex structure, is die-cut, and then the bottle body and tail are die-cut, which is advantageous for ensuring the die-cutting effect.

[0035] Furthermore, the punching drive part 2 is provided to have a mounting plate 21 and a plurality of bases 22 arranged on the mounting plate 21, wherein the plurality of punching units 11 are assigned to the plurality of bases 22 in a one-to-one correspondence, the punching unit 11 being firmly connected to the base 22 by means of a threaded fastening 23, resulting in a simple, reliable structure and easy disassembly and assembly. It is also advantageous for this purpose that the heights of the punching surfaces 12 of the punching units 11 are different. Example II

[0036] Fig. Figure 5 shows a method for separating the separating device described above for rows of plastic containers, comprising the following steps: S1. Securing rows of plastic containers 7: The rows of plastic containers 7 are transferred to the lower clamping element 3, so that the rows of plastic containers 7 are clamped by the interaction of the upper clamping element 4 with the lower clamping element 3. In the present embodiment, it is provided that the lower clamping element 3 is fixedly mounted and the upper clamping element 4 can be raised and lowered, so that after the rows of plastic containers 7 have been conveyed into position, the upper clamping element 4 is lowered to clamp the rows of plastic containers 7 between the upper clamping element 4 and the lower clamping element 3, with reference to in particular Fig. 5a and Fig. 5b. Of course, in other embodiments it is provided that the upper clamping part 4 is also fixedly mounted and the lower clamping part 3 can be raised and lowered, or that both can be raised and lowered separately. S2. Punching: The synchronous lowering of each punching unit 11 is driven by the punching drive part 2, so that the punching surface 12 of each punching unit 11 is punched successively at different heights from the upper end of the first container discharge channel 31, thus separating the containers 71 on the rows of plastic containers 7 from the waste, with reference to in particular Fig. 5c. S3. Exit: The stamped container 71 falls onto the buffer mechanism, so that all containers 71 fall onto the buffer mechanism, and then the buffer mechanism opens, so that the container 71 falls onto the conveyor track 6.

[0037] The stamped container 71 falls from the first container discharge channel 31 onto the first buffer plate 53, with reference to in particular Fig. 5d. After all containers 71 have completely fallen onto the first buffer plate 53, the first buffer plate 53 is turned downwards to be aligned against the upper end of the first deflection plate 51, so that the containers 71 are transferred under gravity onto the first deflection plate 51.

[0038] After all containers 71 have fallen onto the second buffer plate 57, the second buffer plate 57 moves to the side facing away from the conveyor track 6, so that the containers 71 fall onto the conveyor track 6 for conveying, or with reference to in particular Fig. 5e and Fig. 5f.

[0039] The method for separating the separating device for rows of plastic containers according to the present embodiment is provided. Several punching units 11 are punched successively at different heights, which is advantageous for improving punching efficiency, thus avoiding problems with high punching resistance and noise caused by punching all punching units 11 simultaneously. After all containers 71 have fallen onto the second buffer plate 57, the second buffer plate 57 is moved again so that the containers 71 fall simultaneously onto the conveyor 6. This avoids the problems of stacking and crushing caused by the successive falling of containers 71, which is a reasonable approach.

Any person skilled in the art can, without deviating from the scope of the technical solution of the present invention, use the technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention or to modify it into equivalent implementations.
