Description

Technical Field

[0001] The present invention relates to the technical field of collecting and grouping strip-packed products, and more particularly to an automatic collecting system for strip-packed products. Background Art

[0002] In the prior art, multi-lane stick-pack packaging products cover a wide range of markets, including food and pharmaceutical applications, such as coffee and milk powder, and pharmaceutical applications such as solid granules, pills, and oral liquids. In automated multi-lane stick-pack packaging, the stick-pack collection system plays a vital role in connecting the upstream and downstream processes of the fully automated production line, determining its production efficiency. Multi-lane stick-pack filling machines output by row (group), while normal production lines convey and carton the products in rows (groups). Furthermore, to ensure compact packaging, stick-packs require a 90-degree rotation before cartoning. Production speed is calculated based on the number of bags produced per row (group). The greater the number of bags produced per row (group), the higher the production efficiency. During processing, a row (group) is typically treated as a single unit, making it impossible to reject individual bags or sample them individually. Furthermore, since the filler outputs a fixed number of bags per row, this affects the number of bags per carton that the cartoner can pack, impacting product compatibility.

[0003] For example, a multi-lane stick-pack filling machine produces a single row of 10 bags, for example. After the filler, weighing and sampling operations are required. If a bag is underfilled, it must be automatically rejected. However, the normal production line process of rejecting or continuing to transport the bag after sampling would affect subsequent cartoning operations. Therefore, if a bag is detected as unqualified by weighing, the entire row is usually rejected. Then, qualified products are manually selected and boxed. This ultimately severely impacts production efficiency and increases labor costs and intensity.

[0004] In summary, how to improve the production efficiency of stick-packed products is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide an automatic material collection system for stick packs, which can effectively improve the product packaging production efficiency of stick pack products.

[0008] The first conveying device is provided with a weighing station for weighing a single bag of strip-wrapped products and a sampling station for sampling a single bag of strip-wrapped products. The feed port of the collecting device is located below the output end of the second conveying device, and the discharge port of the collecting device is located at the input end of the cartoning machine. The collecting device includes three rotatable synchronous belt material boxes for loading and moving strip-wrapped products. One of the three synchronous belt material boxes can receive a single bag of strip-wrapped products at the feed port, and the other two can cooperate at the discharge port to output grouped strip-wrapped products.

[0009] Preferably, the first conveying device includes a plurality of parallel tracks, a slider slidably connected to the tracks, and a first driving member for driving the slider to move back and forth. The slider is provided with a receiving groove for accommodating the strip-packed products, and a spacing is provided between two adjacent tracks.

[0010] Preferably, a rejection station for rejecting strip-packed products that do not meet the requirements is provided on the track, and the weighing station, the rejection station and the sampling station are arranged in sequence.

[0011] Preferably, the second conveying device includes a circulating rotatable conveyor belt and a second driving member for driving the conveyor belt to rotate.

[0012] Preferably, the collecting device includes a frame, three synchronous belt material boxes that can circulate along the outer periphery of the frame, and a control unit connected to each of the synchronous belt material boxes, and one end of the frame is provided with the feed port and the other end is provided with the discharge port;

[0013] The control unit is used to control one of the three synchronous belt material boxes to receive a single strip-packed product at the feed port, and the other two to cooperate with each other to output grouped strip-packed products at the discharge port.

[0014] Preferably, the synchronous belt material box includes two parallel synchronous belts, a main shaft and a material box for accommodating multiple strip-packed products, each of the synchronous belts is arranged on a driving wheel, the main shaft passes through the two driving wheels, the material box is arranged on the two synchronous belts, and a servo motor is provided on the main shaft, and the servo motor is connected to the control unit.

[0015] Preferably, a photoelectric detection switch is provided at the output end of the second conveying device, and the photoelectric detection switch is used to detect whether the second conveying device outputs the strip-packed product, and the photoelectric detection switch is connected to the control unit.

[0016] Preferably, the discharge port is provided with a pushing device for synchronously pushing out a plurality of strip-packed products, and the pushing device is connected to the control unit.

[0017] Preferably, it also includes a sterilization device for sterilizing the strip-packaged products, the input end of the sterilization device is connected to the discharge port of the first collecting device, the output end of the sterilization device is provided with a synchronous belt conveyor for conveying the strip-packaged products, the output end of the synchronous belt conveyor is connected to the second second conveying device, the output end of the second second conveying device is provided above the feed port of the second collecting device, and the discharge port of the second collecting device is connected to the input end of the cartoning machine.

[0019] When using the automatic stick pack collection system provided by the present invention, the filling machine can fill and output multiple parallel strips of stick packs. The first conveyor device can quickly convey each strip of stick packs longitudinally. During this longitudinal conveying process, individual bags of stick packs can be weighed and sampled to prevent stick packs that do not meet specified requirements from entering the subsequent packaging process. The stick packs can then be transported from the output of the first conveyor device to the input of the second conveyor device, transitioning from longitudinal conveying of entire strips to transverse conveying of individual bags. Therefore, even if unqualified stick packs are found in a strip, their removal will not result in insufficient product for subsequent boxing.

[0020] Afterwards, the stick-packed products can enter the feed port of the collection device from the output end of the second conveyor device. Individual bags of stick-packed products can then be sequentially loaded into the synchronous belt magazine and moved along with it. When the synchronous belt magazine containing multiple stick-packed products moves to the discharge port, multiple stick-packed products can be ejected from the magazine according to discharge requirements. If the number of stick-packed products in a single synchronous belt magazine is insufficient to meet discharge requirements, the next synchronous belt magazine can be controlled to move to the rear of the current magazine, allowing the two synchronous belt magazines to coordinate discharge. Finally, the stick-packed products discharged from the discharge port of the collection device can enter the cartoning machine for cartoning, completing the automatic packaging process for the stick-packed products.

[0021] In summary, the automatic material collection system for stick packs provided by the present invention can effectively improve the product packaging production efficiency of stick pack products. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The core of the present invention is to provide an automatic material collection system for stick packs, which can effectively improve the product packaging production efficiency of stick pack products.

[0037] Please refer to Figures 1 to 10 .

[0038] This embodiment provides an automatic stick pack collection system, comprising: a filling machine 1 for filling and producing stick pack products, a first conveying device 2 for longitudinally conveying the stick pack products in a row, a second conveying device 3 for transversely conveying the stick pack products in individual bags, a cartoning machine 4 for boxing the stick pack products, and a collection device 5. The input end of the first conveying device 2 is located at the output end of the filling machine 1, and the output end of the first conveying device 2 is located at the input end of the second conveying device 3.

[0039] The first conveying device 2 is provided with a weighing station 21 for weighing a single bag of strip-packed products and a sampling station 22 for sampling a single bag of strip-packed products. The feed port 55 of the collecting device 5 is located below the output end of the second conveying device 3, and the discharge port 56 of the collecting device 5 is located at the input end of the cartoning machine 4. The collecting device 5 includes three rotatable synchronous belt material boxes for loading and moving strip-packed products. One of the three synchronous belt material boxes can receive a single bag of strip-packed products at the feed port 55, and the other two can cooperate to output grouped strip-packed products at the discharge port 56.

[0040] It should be noted that a synchronous belt cassette is a box for collecting and holding stick-packed products. Each box is mounted individually on the synchronous belt of the collection device 5. The rotation of the synchronous belt enables the rotational movement of the box, thereby conveying the stick-packed products from the feed port 55 to the discharge port 56. Since the stick-packed products are conveyed on the second conveyor device 3 in a single-bag manner, that is, a single bag of stick-packed products enters the collection device 5 sequentially through the feed port 55, this device can implement a single-bag rejection operation in a fully automated multi-row stick-pack production line, effectively saving labor costs and improving production efficiency. Furthermore, this device utilizes the collection device 5 to meet the product quantity combination requirements of the cartoning machine 4, meeting the production line's ability to produce a variety of product specifications and maximizing profits.

[0041] During actual use, the shape, structure, size, position, etc. of the filling machine 1, the first conveying device 2, the second conveying device 3, the cartoning machine 4 and the collecting device 5 can be determined according to actual conditions and actual needs.

[0042] When using the automatic stick pack collection system provided by the present invention, the filling machine 1 can fill and output multiple parallel strips of stick packs. The first conveyor device 2 can quickly convey each strip of stick packs longitudinally. During this longitudinal conveying process, individual bags of stick packs can be weighed and sampled to prevent stick packs that do not meet specified requirements from entering the subsequent packaging process. The stick packs can then be transported from the output of the first conveyor device 2 to the input of the second conveyor device 3, transitioning from longitudinal conveying of the entire strip to transverse conveying of individual bags. Therefore, even if unqualified stick packs are found in a strip, their removal will not result in a shortage of products for subsequent boxing.

[0043] Afterwards, the stick-packed products can enter the feed port 55 of the collection device 5 from the output end of the second conveyor device 3. Individual bags of stick-packed products can then be sequentially placed into the synchronous belt magazine and moved along with it. When the synchronous belt magazine containing multiple stick-packed products moves to the discharge port 56, the multiple stick-packed products can be ejected from the synchronous belt magazine according to discharge requirements. If the number of stick-packed products in a single synchronous belt magazine is insufficient to meet the discharge requirements, the next synchronous belt magazine can be controlled to move to the rear of the synchronous belt magazine, allowing the two synchronous belt magazines to coordinate discharge. Finally, the stick-packed products discharged from the discharge port 56 of the collection device 5 can enter the cartoning machine 4 for cartoning, completing the automatic packaging process for the stick-packed products.

[0044] In summary, the automatic material collection system for stick packs provided by the present invention can effectively improve the product packaging production efficiency of stick pack products.

[0045] Based on the above embodiment, preferably, the first conveying device 2 includes a plurality of rails 23 arranged in parallel, a slider 24 slidably connected to the rails 23, and a first driving member for driving the slider 24 to move back and forth, the slider 24 is provided with a receiving groove for accommodating the strip-packaged product, and a spacing is provided between two adjacent rails 23.

[0046] It should be noted that the filling machine 1 can produce multiple rows of stick packs, each of which can be delivered longitudinally on the first conveyor 2. The terms "longitudinal" and "lateral" refer to the position of the cartoner 4. Furthermore, the weighing station 21 and the sampling station 22 can be positioned on tracks 23. When the stick packs move along the tracks 23 to the weighing station 21, they can be weighed. When the stick packs move along the tracks 23 to the sampling station 22, they can be sampled. During this process, the stick packs are conveyed in a flat position, eliminating the need for upright bagging. Furthermore, because the tracks 23 are arranged in parallel, the products delivered by the filling machine 1 do not need to be aggregated and can be conveyed directly in a straight line. This reduces the length of the first conveyor 2 and, consequently, the cleanroom floor space.

[0047] Preferably, a rejection station 25 is provided on the track 23 for rejecting unqualified stick-packed products. The weighing station 21, the rejection station 25, and the sampling station 22 are sequentially arranged. When the weighing station 21 detects that the weight of a stick-packed product does not meet the requirements, the stick-packed product can be rejected when it moves to the rejection station 25, thereby promptly rejecting the unqualified product.

[0048] Preferably, the second conveying device 3 includes a rotatable conveyor belt and a second driving member for driving the conveyor belt to rotate. The second driving member may include a servo motor, a rotating shaft connected to the output shaft of the servo motor, a driving wheel sleeved on the outer periphery of the rotating shaft, and a driven wheel used in conjunction with the driving wheel. The conveyor belt is wound around the outer peripheries of the driving wheel and the driven wheel. By controlling the operation of the servo motor, the conveyor belt can be rotated and transmitted. Moreover, the conveyor belt is controlled by the servo motor, which can achieve rapid transportation and rapid positioning.

[0049] It should also be noted that, taking the example of filling machine 1 producing 12 bags of stick-packed products each time, the first conveyor device 2 can simultaneously convey 12 bags of stick-packed products each time. In this case, the rapid conveying displacement of the second conveyor device 3 can be controlled to 15 to 16 bags each time. The extra three or four bags of space are used to start and accelerate the second conveyor device 3. The stick-packed products fall from the tail end of the first conveyor device 2 onto the conveyor belt of the second conveyor device 3, and then enter the collection device 5 for conveying in batches, ensuring that the stick-packed products can be quickly conveyed to the conveyor belt and the synchronous belt material box of the collection device 5. In addition, the stick-packed products are conveyed horizontally at high speed to the conveyor belt and the collection device 5, which can achieve rapid bag erection, reduce the risk of bag erection, and do not require a dedicated bag erection mechanism.

[0050] Preferably, the collecting device 5 includes a frame 54, three synchronous belt material boxes that can circulate along the outer periphery of the frame 54, and a control unit connected to each synchronous belt material box. A feed port 55 is provided at one end of the frame 54 and a discharge port 56 is provided at the other end; the control unit is used to control one of the three synchronous belt material boxes to receive a single strip-packaged product at the feed port 55, and the other two cooperate to output grouped strip-packaged products at the discharge port 56.

[0051] It should be noted that the collection device 5 can achieve single-bag feeding and multi-bag combined discharge, with a single-bag feeding speed of up to 20 bags / second. At the discharge port 56, two sets of synchronous belt magazines are used in conjunction to output products according to the set number of stick-packed products, thereby meeting the cartoning requirements of the cartoning machine 4. For example, any combination of 8, 10, 12, 15 bags, and so on, which does not exceed the number of single synchronous belt magazines, can be discharged. The stick-packed products output by the collection device 5 are already in a compact stand-up bag state, suitable for direct cartoning. Therefore, they can directly enter the material trolley of the cartoning machine 4 at the discharge port 56 for cartoning, and finally enter the boxing stage of the post-packing process.

[0052] Preferably, the synchronous belt magazine includes two parallel synchronous belts, a main shaft, and a magazine for accommodating a plurality of strip packs of products. Each synchronous belt is mounted on a driving pulley, the main shaft passes through the two driving pulleys, and the magazine is mounted on the two synchronous belts. A servo motor is mounted on the main shaft, and the servo motor is connected to a control unit. Therefore, by controlling the operation of the servo motor, the main shaft can be driven to rotate, thereby rotating the driving pulley, and then driving the synchronous belt to rotate, ultimately achieving the movement of the magazine.

[0053] It should be noted that the three synchronous belt material boxes can be named as the first synchronous belt material box 51, the second synchronous belt material box 52 and the third synchronous belt material box 53 respectively. The first synchronous belt material box 51 includes a first synchronous belt, a fourth synchronous belt, a first main shaft and a first material box. The first synchronous belt is provided on the first driving pulley, the fourth synchronous belt is provided on the fourth driving pulley, the first main shaft runs through the first driving pulley and the fourth driving pulley, and the first material box is provided on the first synchronous belt and the fourth synchronous belt;

[0054] The second synchronous belt magazine 52 includes a second synchronous belt, a fifth synchronous belt, a second main shaft and a second magazine. The second synchronous belt is provided on the second driving pulley, the fifth synchronous belt is provided on the fifth driving pulley, the second main shaft passes through the second driving pulley and the fifth driving pulley, and the second magazine is provided on the second synchronous belt and the fifth synchronous belt.

[0055] The third synchronous belt material box 53 includes a third synchronous belt, a sixth synchronous belt, a third main shaft and a third material box. The third synchronous belt is arranged on the third driving wheel, the sixth synchronous belt is arranged on the sixth driving wheel, the third main shaft passes through the third driven wheel and the sixth driving wheel, the third material box is arranged on the third synchronous belt and the sixth synchronous belt, the first synchronous belt, the second synchronous belt, the third synchronous belt, the fourth synchronous belt, the fifth synchronous belt and the sixth synchronous belt are arranged side by side in sequence, and the first main shaft, the second main shaft and the third main shaft are all provided with servo motors, and the servo motors are connected to the control device.

[0056] It should also be noted that the first synchronous belt is arranged on the first driving wheel, the first driven wheel and the first driven wheel, the second synchronous belt is arranged on the second driving wheel, the second driven wheel and the second driven wheel, the third synchronous belt is arranged on the third driving wheel, the third driven wheel and the third driven wheel, the fourth synchronous belt is arranged on the fourth driving wheel, the fourth driven wheel and the fourth driven wheel, the fifth synchronous belt is arranged on the fifth driving wheel, the fifth driven wheel and the fifth driven wheel, and the sixth synchronous belt is arranged on the sixth driving wheel, the sixth driven wheel and the sixth driven wheel.

[0057] Moreover, the first driving wheel, the second driven wheel, the third driven wheel, the fourth driving wheel, the fifth driven wheel and the sixth driven wheel are arranged in an aligned manner, and the first main shaft passes through the first driving wheel, the second driven wheel, the third driven wheel, the fourth driving wheel, the fifth driven wheel and the sixth driven wheel in sequence. The first driven wheel, the second driving wheel, the third driven wheel, the fourth driven wheel, the fifth driving wheel and the sixth driven wheel are arranged in an aligned manner, and the second main shaft passes through the first driven wheel, the second driving wheel, the third driven wheel, the fourth driven wheel, the fifth driving wheel and the sixth driven wheel in sequence. The first follower wheel, the second follower wheel, the third driving wheel, the fourth follower wheel, the fifth follower wheel and the sixth driving wheel are arranged in an aligned manner, and the third main shaft passes through the first follower wheel, the second follower wheel, the third driving wheel, the fourth follower wheel, the fifth follower wheel and the sixth driving wheel in sequence. By driving the first main shaft, the second main shaft and the third main shaft to operate, the first material box, the second material box and the third material box can be driven to move and transport,

[0058] It should be further explained that the preset position of the frame 54 can be set as the origin, which is used as a reference to control the movement of the receiving slots of the first, second, and third material boxes. Moreover, the frame 54 can be set to a shuttle-like structure, and the first synchronous belt material box 51, the second synchronous belt material box 52, and the third synchronous belt material box 53 can be controlled to rotate clockwise along the outer periphery of the frame 54. By controlling the operation of the servo motors of the first, second, and third spindles to drive the movement of the first, second, and third material boxes, each movement of each material box can move the receiving slot of the material box once, ensuring that each receiving slot can accommodate one product. Through the absolute displacement control method, while ensuring the precise positioning of the first, second, and third material boxes, each synchronous belt material box can be moved continuously and uninterruptedly, achieving the purpose of rapid material collection.

[0059] Preferably, a photoelectric detection switch 6 is provided at the output end of the second conveying device 3, and the photoelectric detection switch 6 is used to detect whether the second conveying device 3 outputs a strip-packaged product. The photoelectric detection switch 6 is connected to the control unit to ensure that whenever the second conveying device 3 outputs a strip-packaged product to the collecting device 5, the control unit can control the servo motor to operate to ensure that there is a material box for receiving the material at the feed port 55.

[0060] Preferably, the discharge port 56 is provided with a pusher device 7 for simultaneously pushing out multiple stick-packed products. The pusher device 7 is connected to the control unit. Specifically, when the stick-packed products, along with the magazine, reach the discharge port 56 and need to be discharged, the pusher device 7 is controlled to operate, thereby simultaneously pushing out the multiple stick-packed products. The multiple stick-packed products then enter the cartoning machine 4 for cartoning, thus completing the automatic packaging process for the stick-packed products.

[0061] In order to further illustrate the operation process of the material collecting device 5 , the operation process of the material collecting device 5 is described below with an example. Figure 3-10 The following is a timing diagram of the operation of the material collection device 5. Sequence A is the initial position of the material collection device 5, at which time the three groups of synchronous belt cassettes are in a standby state: the first synchronous belt cassette 51, the second synchronous belt cassette 52, and the third synchronous belt cassette 53. After the material collection device 5 begins collecting, the sequential operation sequence is from B to H. The basic process parameters of the material collection device 5 include: each group of synchronous belt cassettes can receive 20 strip packs of products, the feeding method is single product feeding, and the discharge method is the simultaneous discharge of each group of 6 products.

[0062] Sequence A: The three groups of material boxes are arranged in sequence at the original position. The first synchronous belt material box 51 waits for incoming materials at the feed port 55. The second synchronous belt material box 52 moves with the first synchronous belt material box 51. The third synchronous belt material box 53 moves with the second synchronous belt material box 52.

[0063] Sequence B: The first synchronous belt cassette 51 is filled with materials and reaches the discharge port 56, discharging 6 pieces at a time. The second synchronous belt cassette 52 feeds materials at the feed port 55, and the third synchronous belt cassette 53 follows the second synchronous belt cassette 52.

[0064] Sequence C: The first synchronous belt cassette 51 has two products remaining at the discharge port 56, which cannot meet the requirement of discharging all six products simultaneously. At this time, the second synchronous belt cassette 52 is full and reaches the discharge port 56. This position is calculated based on the current position of the first synchronous belt cassette 51. The first and second synchronous belt cassettes 51, 52 can then be used to output six products. At this time, the third synchronous belt cassette 53 is in the feeding state.

[0065] Sequence D: After the first synchronous belt cassette 51 has finished discharging the last two products, it immediately follows the third synchronous belt cassette 53. This position is calculated based on the current position of the third synchronous belt cassette 53. At this time, the second synchronous belt cassette 52 is discharging at the discharge port 56.

[0066] Sequence E: The second synchronous belt cassette 52 has four products remaining at the discharge port 56, which cannot meet the requirement of discharging six products simultaneously. At this time, the third synchronous belt cassette 53 is full of products and reaches the discharge port 56, which is calculated based on the current position of the second synchronous belt cassette 52. The second and third synchronous belt cassettes 52, 53 can then be used to output six products. At this time, the first synchronous belt cassette 51 is in the feeding state.

[0067] Sequence F: The second synchronous belt cassette 52 finishes discharging the last four products and immediately follows to the tail end of the first synchronous belt cassette 51. This position is calculated based on the current position of the first synchronous belt cassette 51. At this time, the third synchronous belt cassette 53 discharges products at the discharge port 56.

[0068] Sequence G: The number of products in the third synchronous belt cassette 53 at the discharge port 56 reaches an integer multiple of 6 and can be discharged. After the discharge is completed, the product directly reaches the tail end of the second synchronous belt cassette 52 to follow. The first synchronous belt cassette 51 waits in the waiting area for the third synchronous belt cassette 53 to leave the discharge port 56, and then enters the discharge port 56 position. At this time, the second synchronous belt cassette 52 is feeding at the feed port 55.

[0069] Sequence H: the first synchronous belt material box 51 discharges material at the discharge port 56 , the third synchronous belt material box 53 reaches the tail end of the second synchronous belt material box 52 and moves along, and the second synchronous belt material box 52 feeds material at the feed port 55 , which is similar to the state of sequence B.

[0070] The material collection device 5 utilizes a three-axis synchronous belt transmission method for material collection. Through the flexible combination of two sets of magazine outputs, it can meet the various configuration requirements of the cartoning machine 4 and enhance the compatibility of the production line. Furthermore, the material collection device 5 uses a servo motor to control the movement of the magazine. With absolute displacement control, while ensuring precise positioning of the magazine, the magazine can achieve accurate and continuous movement during the feeding process, achieving rapid material collection.

[0071] Preferably, it also includes a sterilization device 8 for sterilizing the strip-packaged products. The input end of the sterilization device 8 is connected to the discharge port 56 of the first collecting device 5. The output end of the sterilization device 8 is provided with a synchronous belt conveyor 9 for conveying the strip-packaged products. The output end of the synchronous belt conveyor 9 is connected to the second second conveying device 3. The output end of the second second conveying device 3 is provided above the feed port 55 of the second collecting device 5. The discharge port 56 of the second collecting device 5 is connected to the input end of the cartoning machine 4.

[0072] It should be noted that the structural principle of the strip packaging products that need to be sterilized is as follows Figure 2 As shown, two aggregation operations are required when adding a sterilization process. The first aggregation is performed after the filling machine 1 produces the strip-packed products to ensure that the strip-packed products can be collected in the container of the sterilization device 8. The arrangement of the strip-packed products after the sterilization operation is completed will be affected and cannot be directly boxed. At this time, the strip-packed products need to be re-arranged and aggregated. After the second aggregation, they can be successfully boxed.

[0073] Preferably, at least two synchronous belt conveyors 9 with different transmission speeds are provided between the output end of the sterilization device 8 and the second second conveying device 3, and the height of each synchronous belt conveyor 9 decreases successively along the conveying direction of the strip-packed products.

[0074] It should be noted that the products after sterilization are relatively concentrated, requiring multiple sets of synchronous belt conveyors 9. The speed difference of the synchronous belt conveyors 9 is used to widen the spacing between the strip-packed products, rearrange the strip-packed products, and realize the separation operation of the strip-packed products, ensuring that the strip-packed products can stably enter the collection device 5, ensuring the efficient operation of the production line. In addition, the height of the synchronous belt conveyors 9 decreases successively, meaning that the synchronous belt conveyor 9 closest to the sterilization device 8 is the highest, and the height of the subsequent synchronous belt conveyors 9 gradually decreases, and can be as low as the collection device 5. The purpose of setting the height difference for multiple sets of synchronous belt conveyors 9 is to enable more stable transmission of the strip-packed products.

[0075] In addition, it should be noted that a paddle can be provided on the synchronous belt conveyor 9 to guide and push the movement of the strip-wrapped products, so as to convey the strip-wrapped products to the collection device 5 at high speed, thereby realizing rapid collection and solving problems such as irregular distribution of the strip-wrapped products after sterilization.

[0076] It should be noted that the first conveying device 2 and the second conveying device 3 mentioned in this application document are only used to distinguish the difference in position and there is no order of precedence.

[0077] In addition, it should be noted that the orientation or positional relationship indicated by "in and out" etc. in this application is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of simplifying the description and facilitating understanding, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
