Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging equipment, and more particularly to a strip pack arranging device. Background Technology

[0002] After the strip bags (short for strip-shaped packaging bags) are packaged by the strip bagging machine, they must smoothly enter the guide mechanism. The connection between the strip bagging machine and the guide mechanism is crucial. A prior application, CN115744231A, discloses a continuous strip bag pushing mechanism and a strip bag conveying device. This mechanism uses multiple first push plates to continuously push strip bags forward on the first conveyor bottom rail, improving conveying efficiency and avoiding the drawbacks of reciprocating motion being greatly affected by inertia. It also helps keep rows of strip bags neatly arranged, preventing jamming or rear-end stacking. When a strip bag pushed by a flipping push plate needs to be sampled and weighed, the flipping push plate flips upward to separate from the strip bag and continues to move forward. After the strip bag is weighed, the next push plate takes over, eliminating waiting time and further improving conveying efficiency. The distance between two adjacent rows of strip bags on the first conveyor bottom rail is twice the distance between two adjacent first push plates, ensuring stable operation of the continuous strip bag pushing mechanism and preventing rear-end stacking of strip bags during weighing.

[0003] As users have higher requirements for packaging boxes, for strips with long horizontal seals, a portion of the horizontal seal needs to be folded in half before being packed into boxes to save packaging space. Traditional strip conveyor devices are not suitable for this purpose. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a simple strip pack folding device that can fold the strip pack horizontally to reduce its length.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A strip pack assembling device includes a conveying track and a bag folding station and a gathering station arranged sequentially along the length of the conveying track. The bag folding station is provided with a clamping member and a bending mechanism for bending the strip packs at one end near the gathering station. The bending mechanism includes a mounting member that can reciprocate along the width of the conveying track and a bending portion provided on the mounting member.

[0007] As a further improvement to the above technical solution: the end of the bag folding station away from the gathering station is also provided with a multiple station, the multiple station is provided with 2n first conveying channels along the width direction of the conveying track, n≥1, the bag folding station is provided with n second conveying channels along the width direction of the conveying track, and the second conveying channels can reciprocate along the width direction of the conveying track.

[0008] As a further improvement to the above technical solution: a groove is provided on the side wall of the second conveying channel, the clamping member is disposed in the groove, and the bending part is disposed between the clamping member and the gathering station.

[0009] As a further improvement to the above technical solution: the multiple station is provided with positioning components at both ends, and the positioning components are connected to positioning drive components to realize reciprocating movement along the length direction of the conveying track.

[0010] As a further improvement to the above technical solution: the strip pack aligning device also includes a clamping drive mechanism, which includes a first telescopic drive member, a clamping member mounting base and a first guide slider. The clamping member is disposed on the clamping member mounting base. The first telescopic drive member is connected to the clamping member mounting base. The clamping member mounting base is provided with a first linear guide rail that cooperates with the first guide slider.

[0011] As a further improvement to the above technical solution, buffer components are also provided at both ends of the clamping mounting base.

[0012] As a further improvement to the above technical solution: the first telescopic drive and the first guide slider are installed on the lower side of the conveying track.

[0013] As a further improvement to the above technical solution: the bending mechanism further includes a second telescopic drive component and a second guide slider, the second telescopic drive component being connected to the mounting component, and the mounting component being provided with a second linear guide rail that cooperates with the second guide slider.

[0014] As a further improvement to the above technical solution: the bending mechanism further includes a support, the second telescopic drive member and the second guide slider are respectively disposed on both sides of the support, the second linear guide rail is provided with a connecting block, the support is provided with a notch, the connecting block is located in the notch and connected to the second telescopic drive member.

[0015] As a further improvement to the above technical solution: the mounting component is located below the conveying track.

[0016] Compared with the prior art, the advantages of the present invention are as follows: The strip pack aligning device disclosed in the present invention has a clamping component and a bending mechanism at one end of the bag folding station near the gathering station. After the strip pack is conveyed into place, the clamping component clamps the horizontal seal of the strip pack to fix it in place. Then, the mounting component drives the bending part to move along the width direction of the conveying track, thereby bending the horizontal seal of the strip pack by about 90°. The clamping component releases the strip pack, and the strip pack continues to be conveyed to the gathering station. The bent horizontal seal is further bent by 180° to complete the fold. The structure is simple and effective, which can shorten the length of the strip pack and save the space of the packaging box. Attached Figure Description

[0025] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Figures 1 to 4 An embodiment of the pack arranging device of the present invention is shown. The pack arranging device of this embodiment includes a conveying track 1 and a bag folding station 3 and a gathering station 4 arranged sequentially along the length direction of the conveying track 1. The bag folding station 3 is provided with a clamping member 32 and a bending mechanism 6 for bending the pack at one end near the gathering station 4. The bending mechanism 6 includes a mounting member 62 that can reciprocate along the width direction of the conveying track 1 and a bending portion 33 provided on the mounting member 62.

[0028] In this embodiment of the strip pack aligning device, the bag folding station 3 is equipped with a clamping member 32 and a bending mechanism 6 at one end near the gathering station 4. After the strip pack is conveyed into place, the clamping member 32 clamps the horizontal seal of the strip pack to fix it in place. Then, the mounting member 62 drives the bending part 33 to move along the width direction of the conveying track 1, thereby bending the horizontal seal of the strip pack by about 90°. The clamping member releases the strip pack, and the strip pack continues to be conveyed to the gathering station 4 (specifically, the third conveying channel 41 of the gathering station 4, with the downstream of each third conveying channel 41 gradually converging). The bent horizontal seal is further bent by 180° to complete the folding. The structure is simple and effective, which can shorten the length of the strip pack and save the space of the packaging box.

[0029] Furthermore, in this embodiment, a multiple station 2 is also provided at the end of the bag folding station 3 away from the gathering station 4. That is, the multiple station 2 is located upstream of the bag folding station 3. The multiple station 2 has 2n first conveying channels 21 along the width direction of the conveying track 1, where n≥1. The bag folding station 3 has n second conveying channels 31 along the width direction of the conveying track 1. The second conveying channels 31 can move back and forth along the width direction of the conveying track 1. Since the number of second conveying channels 31 in the bag folding station 3 is only half that of the first conveying channels 21 in the multiple station 2, the spacing between the second conveying channels 31 is twice the spacing between the first conveying channels 21. This ensures that there is enough space on the sides of the second conveying channels 31 to fold the bag horizontally and avoids obstruction between adjacent bags. During operation, the strips in the first conveyor channel 21 (the 1st, 3rd, 5th, etc.) with odd numbers can be conveyed to the corresponding second conveyor channel 31. Then, the bag folding station 3 moves laterally along the width direction so that the first conveyor channel 21 (the 2nd, 4th, 6th, etc.) with even numbers are aligned with the second conveyor channel 31. The strips in the first conveyor channel 21 with even numbers can then enter the second conveyor channel 31. The structure is reasonable and effective.

[0030] Furthermore, in this embodiment, a groove 311 is provided on the side wall of the second conveying channel 31, and the clamping member 32 is disposed in the groove 311. The bending portion 33 is disposed between the clamping member 32 and the gathering station 4, or in other words, the bending portion 33 is located downstream of the clamping member 32. By providing a groove 311 on the side wall of the second conveying channel 31 and arranging the clamping member 32 in the groove 311, the layout is compact and occupies little space. The clamping member 32 can cooperate with the other side wall of the second conveying channel 31 to clamp the strip package. The structure is simple and effective.

[0031] Furthermore, in this embodiment, positioning components 22 (e.g., positioning plates, positioning rods, etc.) are provided at both ends of the multiple station 2. The positioning components 22 are connected to positioning drive components 23 (e.g., cylinders, hydraulic cylinders, or electric push rods, etc.) to achieve reciprocating movement along the length direction of the conveying track 1. After the strip package is in place, the positioning components 22 at both ends move closer together and clamp under the action of the positioning drive component 23, thereby positioning the strip package between the positioning components 22 at both ends, preventing back-and-forth movement, ensuring that all strip packages can reach the target position, facilitating the subsequent clamping and bending processes. The structure is reasonable and effective.

[0032] Furthermore, in this embodiment, the strip pack aligning device also includes a clamping drive mechanism 5. The clamping drive mechanism 5 includes a first telescopic drive member 51 (e.g., a cylinder, hydraulic cylinder, or electric push rod), a clamping member mounting base 52, and a first guide slider 53. The clamping member 32 is mounted on the clamping member mounting base 52. The first telescopic drive member 51 is connected to the clamping member mounting base 52. The clamping member mounting base 52 is provided with a first linear guide rail 54 that cooperates with the first guide slider 53. When it is necessary to clamp the strip pack horizontally, the first telescopic drive member 51 drives the clamping member mounting base 52 to move. Each clamping member 32 and the first linear guide rail 54 move synchronously with the clamping member mounting base 52. The first guide slider 53 cooperates with the first linear guide rail 54 to provide guidance for the movement of the clamping member mounting base 52, ensuring a smooth and stable movement process, avoiding deviation, and reducing movement resistance. Preferably, multiple first guide sliders 53 are arranged along the length direction of the first linear guide rail 54 to ensure the overall guiding effect of the first linear guide rail 54.

[0033] Furthermore, in this embodiment, buffer members 55 are also provided at both ends of the clamping member mounting base 52. The buffer members 55 at both ends can provide a buffering effect for the rapid reciprocating movement of the clamping member mounting base 52, avoiding excessive movement, and also improving the speed of directional switching of the clamping member mounting base 52 to a certain extent. The buffer members 55 can be, for example, springs, elastic rubber blocks, etc.

[0034] In a preferred embodiment, the first telescopic drive member 51 and the first guide slider 53 are installed on the lower side of the conveying track 1, which can effectively utilize the space on the lower side of the conveying track 1, making the device structure more compact and the appearance quality higher. It also helps to reduce the risk of contamination of the space above the conveying track 1 by the moving parts. Furthermore, the first telescopic drive member 51 can be directly installed on the lower side of the conveying track 1, and the first guide slider 53, etc., can be installed on the lower side of the conveying track 1 through a connecting plate, etc.

[0035] Furthermore, in this embodiment, the bending mechanism 6 also includes a second telescopic drive member 61 (e.g., a cylinder, hydraulic cylinder, or electric push rod) and a second guide slider 63. The second telescopic drive member 61 is connected to the mounting member 62, and the mounting member 62 is provided with a second linear guide rail 64 that cooperates with the second guide slider 63. When the strip needs to be bent horizontally, the second telescopic drive member 61 drives the mounting member 62 to move. The bending part 33 and the second linear guide rail 64 move synchronously with the mounting member 62. The second guide slider 63 cooperates with the second linear guide rail 64 to provide guidance for the movement of the mounting member 62, ensuring a smooth and stable movement process, avoiding deviation, and reducing movement resistance. Preferably, multiple second guide sliders 63 are provided along the length direction of the second linear guide rail 64 to ensure the overall guiding effect of the second linear guide rail 64.

[0036] Furthermore, in this embodiment, the bending mechanism 6 also includes a support 65, a second telescopic drive member 61 and a second guide slider 63 respectively disposed on both sides of the support 65, a connecting block 66 provided on the second linear guide rail 64, and a notch 651 provided on the support 65. The connecting block 66 is located at the notch 651 and connected to the second telescopic drive member 61. The second telescopic drive member 61 can drive the mounting member 62 to reciprocate through the connecting block 66 and the second linear guide rail 64. The notch 651 does not obstruct the reciprocating movement of the connecting block 66. The overall structure is compact, occupies little space, and has a reasonable layout.

[0037] As a preferred embodiment, the mounting component 62 is located below the conveying track 1, which can effectively utilize the space below the conveying track 1, making the device structure more compact and the appearance quality higher. It also helps to reduce the risk of contamination of the space above the conveying track 1 by moving parts.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
