Description

Technical Field

[0001] This invention relates to the field of flexible packaging material feeding technology, and more specifically, to a flexible packaging material feeding production line. Background Technology

[0002] In the pharmaceutical industry, rubber stoppers, aluminum caps, and combination caps are widely used. Typically, rubber stoppers, aluminum caps, and combination caps are placed in soft bags and sealed before use to facilitate their preservation and transportation.

[0003] In the existing technology, when feeding rubber stoppers, aluminum caps and combination caps, the main method is to manually use a blade to cut an opening in the soft bag, and then manually pour out the rubber stoppers, aluminum caps and combination caps from the opening. The poured-out rubber stoppers, aluminum caps and combination caps are then transported to the work station by manual labor. This method is labor-intensive, has high labor costs and low work efficiency.

[0004] Therefore, how to achieve automatic feeding of flexible packaging materials, reduce manual labor intensity, reduce labor costs, and improve work efficiency is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

When the second material distribution baffle blocks the branch conveyor line, the material is diverted and enters the first transfer guide under the baffle's limiting position. When the second material distribution baffle allows the branch conveyor line to pass, the material continues to be conveyed along the branch conveyor line. A third material distribution baffle is located at the junction of the second transfer guide and the branch conveyor line. When the material is conveyed to the position of the third material distribution baffle, the material is diverted and enters the second transfer guide under the limiting position of the third material distribution baffle.

[0042] The raw material warehouse is equipped with pallets for placing cartons containing the soft bags;

[0043] The unpacking, bag-removing, and stacking device is used to unpack the carton, remove the soft bags from the carton, and then load them into the soft bag carrier.

[0044] A bag material buffer position is used to place the soft bag carrier containing the soft bag;

[0045] An empty carrier temporary storage location is provided for placing the empty soft bag carrier.

[0046] An AGV (Automated Guided Vehicle) is used to transport the carton to the unpacking, bagging, and palletizing device, transfer the soft bag carrier containing the soft bag to the bag material buffer position, transfer the soft bag carrier in the bag material buffer position to the soft bag feeding station, and transfer the empty soft bag carrier at the soft bag feeding station to the empty carrier temporary storage position.

[0047] Optionally, the unpacking, bagging, and palletizing device includes:

[0055] The flexible packaging material feeding production line provided by this invention operates as follows: A first robot feeds a flexible bag from a positioning station into a flexible bag cutting device. The cutting device cuts open the opening of the bag containing material. Then, the first robot moves the cut bag above a hopper, pouring the material from the bag opening onto the hopper. Because the hopper is tilted at the entrance of the distribution conveyor line, the material automatically slides down the hopper to the distribution conveyor line under its own weight. The distribution conveyor line then transports the material to the usage station for use. The positioning station is used to place and position the flexible bags to ensure they are in the correct position so that the first robot can pick them up and feed them into the flexible bag cutting device.

[0056] It can be seen that the flexible packaging material feeding production line can realize the automatic feeding and automatic bag cutting functions of the flexible bag cutting device, and can realize the automatic pouring and automatic material conveying functions of the material inside the flexible bag. This can avoid manual bag opening, pouring and material transfer. Therefore, it realizes the automatic feeding of flexible packaging materials, reduces the intensity of manual labor, reduces labor costs and improves work efficiency. Attached Figure Description

[0081] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0082] The core of this invention is to provide a production line for feeding flexible packaging materials, which can realize automatic feeding of flexible packaging materials, reduce manual labor intensity, reduce labor costs, and improve work efficiency.

[0083] Please refer to Figure 1This invention provides a flexible packaging material feeding production line, including a flexible bag cutting device 1, a material distribution conveyor line 2, and a first robot 3. The flexible bag cutting device 1 is used to cut open the opening of a flexible bag 10 containing material (e.g., ...). Figure 8 (As shown); the material distribution conveyor line 2 is used to transport materials to the workstation. The inlet of the material distribution conveyor line 2 is equipped with an inclined hopper 213 (as shown). Figure 2 (As shown); the first robot 3 is used to feed the soft bag 10 from the positioning station into the soft bag cutting device 1, and move the cut-open soft bag 10 to above the hopper 213, pouring the material inside the soft bag 10 from the bag opening onto the hopper 213, so that the material automatically slides down the hopper 213 to the material distribution conveyor line 2. It should be noted that the positioning station is the station for positioning the soft bag 10, used to place the soft bag 10 to be opened and to position it in that position so that the first robot 3 can pick up the soft bag 10 to be opened.

[0084] In other words, during operation, the first robot 3 feeds the soft bag 10 from the positioning station into the soft bag cutting device 1. The soft bag cutting device 1 cuts open the opening of the soft bag 10 containing material. Then, the first robot 3 moves the cut soft bag 10 above the hopper 213 and pours the material from the opening of the soft bag 10 onto the hopper 213. Since the hopper 213 is inclined at the entrance of the material distribution conveyor line 2, when the material is poured into the hopper 213, it automatically slides down the hopper 213 to the material distribution conveyor line 2 under the action of gravity. Then, the material distribution conveyor line 2 transports the material to the use station for use. It should be noted that the positioning station is used to place and position the soft bag 10 to ensure that the soft bag 10 has the correct position so that the first robot 3 can pick up the soft bag 10 from the positioning station and feed it into the soft bag cutting device 1.

[0085] As can be seen, the embodiments of the present invention can realize the automatic feeding and automatic bag cutting functions of the soft bag cutting device 1, and can realize the automatic pouring and automatic material conveying functions of the material in the soft bag 10. This can avoid manual opening of the bag, pouring of material and transfer of material. Therefore, it realizes the automatic feeding of soft package material, reduces the intensity of manual labor, reduces labor costs and improves work efficiency.

[0086] It should be noted that this embodiment does not limit the specific number of the soft bag cutting device 1 and the first robot 3. In some embodiments, the number of the soft bag cutting device 1 and the first robot 3 are two each. One soft bag cutting device 1 and one first robot 3 are arranged together on the same side of the material distribution conveyor line 2. The two soft bag cutting devices 1 can be symmetrically arranged on both sides of the material distribution conveyor line 2. Similarly, the two first robots 3 can be symmetrically arranged on both sides of the material distribution conveyor line 2, that is, the material distribution conveyor line 2 is used for dual-station feeding.

[0087] It should be noted that this embodiment does not limit the specific structure of the material conveying line 2, as long as it can convey materials to the workstation.

[0088] Please refer to Figure 2 In some embodiments, the material distribution conveyor line 2 includes a main conveyor line 21 and at least one branch conveyor line 22 disposed on the side of the main conveyor line 21. The branch conveyor line 22 is used to connect with the workstation. When there are at least two branch conveyor lines 22, each branch conveyor line 22 is spaced apart along the length of the main conveyor line 21 on any side of the main conveyor line 21. The main conveyor line 21 is provided with movable first material distribution baffles 23 at the positions corresponding to each branch conveyor line 22. The first material distribution baffles 23 can block or allow the main conveyor line 21 to pass. When the first material distribution baffles 23 block the main conveyor line 21, the material is diverted and conveyed along the branch conveyor line 22 under the limitation of the first material distribution baffles 23. When the first material distribution baffles 23 allow the main conveyor line 21 to pass, the material continues to be conveyed along the main conveyor line 21.

[0089] In other words, this embodiment utilizes the main conveyor line 21 to transport materials to various branch conveyor lines 22, which then transport the materials to the designated workstations. At the junctions of the branch conveyor lines 22 and the main conveyor line 21, movable first dividing baffles 23 are used to allow materials to continue being transported along the main conveyor line 21 or along the branch conveyor lines 22 to the corresponding workstations. That is, this embodiment can transport materials to different workstations.

[0090] Understandably, the first material distribution baffle 23 can switch between a first position and a second position. When the first material distribution baffle 23 moves to the first position, it blocks the main conveyor line 21, preventing the material from continuing to be conveyed along the main conveyor line 21. Consequently, under the limitation of the first material distribution baffle 23, the material is diverted to enter the branch conveyor line 22, and then the material is sent to the workstation corresponding to the branch conveyor line 22. When the first material distribution baffle 23 moves to the second position, it clears the main conveyor line 21, allowing the material to continue to be conveyed along the main conveyor line 21 without entering the current branch conveyor line 22.

[0091] It should be noted that the first material distribution baffle 23, which is positioned along the main conveyor line 21 at the location corresponding to the last branch conveyor line 22 in its conveying direction, can also be a fixed material distribution baffle. This fixed baffle is located at the position that blocks the main conveyor line 21 and remains in that position at all times. When the material conveyed by the main conveyor line 21 reaches the fixed baffle, the baffle prevents the material from continuing to move along the main conveyor line 21 and redirects the material to enter the last branch conveyor line 22 in the conveying direction of the main conveyor line 21. This simplifies the structure of the first material distribution baffle 23 corresponding to the last branch conveyor line 22 in the conveying direction of the main conveyor line 21.

[0092] Furthermore, please combine Figure 2 and Figure 3 In some embodiments, the branch conveyor line 22 is inclined so that its end has a preset height difference from the main conveyor line 21, and the end of the branch conveyor line 22 is provided with a transfer guide plate 24 for accessing the workstation. That is, in this embodiment, the end of the branch conveyor line 22 and the main conveyor line 21 are at different height levels. The branch conveyor line 22 plays the role of transferring materials between different height levels. This is beneficial for setting the ends of the main conveyor line 21 and the branch conveyor line 22 on different floors, that is, setting the main conveyor line 21 and the workstation on different floors, realizing automatic material transfer across floors. This is beneficial for the automatic turnover of materials in the space at the height level of the main conveyor line 21, ensuring that the space at the height level of the main conveyor line 21 meets the requirements of the material turnover environment.

[0093] Additionally, when the material is conveyed to the end of the branch conveyor line 22, a transfer guide plate 24 is used to guide the material to the usage station. The transfer guide plate 24 can be tilted to allow the material to automatically slide down along the transfer guide plate 24 to the usage station. In some embodiments, a vibratory feeder can be installed at the usage station to allow the material to enter the vibratory feeder and be supplied to the required station.

[0094] In addition, to achieve mixed production of different materials, please combine... Figure 2 , Figure 3 and Figure 4In some embodiments, there are two main conveyor lines 21, arranged side by side, with different heights. A horizontal conveying section 221 is provided at one end of each branch conveyor line 22 near the main conveyor line 21, located below the two main conveyor lines 21. Each of the two main conveyor lines 21 has an inclined guide plate 27 corresponding to the respective branch conveyor line 22. The guide plate 27 is used to direct the material on the main conveyor line 21 into the corresponding branch conveyor line 22 after the material is redirected when the corresponding first material distribution baffle 23 blocks the main conveyor line 21. Each branch conveyor line 22 has two transition guide plates 24 at its end along its conveying direction, namely the first transition guide plate 241. The second transfer guide plate 242 and the first transfer guide plate 241 are provided with a movable second material distribution baffle 25 at the position where they meet the branch conveyor line 22. The second material distribution baffle 25 can block or allow the branch conveyor line 22 to pass. When the second material distribution baffle 25 blocks the branch conveyor line 22, the material is diverted into the first transfer guide plate 241 under the limitation of the second material distribution baffle 25. When the second material distribution baffle 25 allows the branch conveyor line 22 to pass, the material continues to be conveyed along the branch conveyor line 22. The second transfer guide plate 242 is provided with a third material distribution baffle 26 at the position where it meets the branch conveyor line 22. When the material is conveyed to the position of the third material distribution baffle 26, the material is diverted into the second transfer guide plate 242 under the limitation of the third material distribution baffle 26.

[0095] In other words, this embodiment uses two main conveyor lines 21 to convey materials to each branch conveyor line 22. For ease of description, the two main conveyor lines 21 are referred to as the first main conveyor line 211 and the second main conveyor line 212, respectively. Each branch conveyor line 22 acts as a mixed conveyor line to convey the materials conveyed by the first main conveyor line 211 and the second main conveyor line 212. Figure 3As shown, the height of the second main conveyor line 212 is lower than that of the first main conveyor line 211, which facilitates the installation of a guide plate 27 on the second main conveyor line 212 and avoids interference between the guide plate 27 on the second main conveyor line 212 and the first main conveyor line 211, so as to ensure that the first main conveyor line 211 and the second main conveyor line 212 are respectively connected to the same branch conveyor line 22. It is understood that the first main conveyor line 211 and the second main conveyor line 212 are respectively equipped with a first material distribution baffle 23 and a guide plate 27 at the positions corresponding to each branch conveyor line 22. In addition, each branch conveyor line 22 is equipped with a horizontal conveying section 221 at the end near the main conveyor line 21. The horizontal conveying section 221 is located below the first main conveyor line 211 and the second main conveyor line 212. The material conveyed by the first main conveyor line 211 falls into the horizontal conveying section 221 along the guide plate 27 set on the first main conveyor line 211 and is then conveyed by the corresponding branch conveyor line 22. The material conveyed by the second main conveyor line 212 falls into the horizontal conveying section 221 along the guide plate 27 set on the second main conveyor line 212 and is then conveyed by the corresponding branch conveyor line 22. That is, when the first material distribution baffle 23 is set on the first main conveyor line 211, the material will fall into the horizontal conveying section 221 along the guide plate 27 set on the second main conveyor line 212 and be conveyed by the corresponding branch conveyor line 22. When the first main conveyor line 211 is blocked, the first material distribution baffle 23 causes the material on the first main conveyor line 211 to change direction and enter the corresponding branch conveyor line 22 along the corresponding guide plate 27; when the first material distribution baffle 23 installed on the second main conveyor line 212 blocks the second main conveyor line 212, the first material distribution baffle 23 causes the material on the second main conveyor line 212 to change direction and enter the corresponding branch conveyor line 22 along the corresponding guide plate 27; that is, the first main conveyor line 211 uses the first material distribution baffle 23 and guide plate 27 of its corresponding branch conveyor line 22 to allow the material of the first main conveyor line 211 to enter the branch conveyor line 22, and the second main conveyor line 212 uses the first material distribution baffle 23 and guide plate 27 of its corresponding branch conveyor line 22 to allow the material of the second main conveyor line 212 to enter the branch conveyor line 22.

[0096] Meanwhile, each branch conveyor line 22 is equipped with two transfer guide plates 24 at its end. For ease of description, the two transfer guide plates 24 are referred to as the first transfer guide plate 241 and the second transfer guide plate 242, respectively. The first transfer guide plate 241 and the second transfer guide plate 242 are located on the side of the branch conveyor line 22 along the conveying direction of the branch conveyor line 22. The second transfer guide plate 242 is defined as being closer to the outlet position at the end of the branch conveyor line 22. Using the limiting position of the second material distribution baffle 25, the material conveyed by the first main conveyor line 211 or the second main conveyor line 212 can enter the first transfer guide plate 241. Using the limiting position of the third material distribution baffle 26, the material conveyed by the first main conveyor line 211 or the second main conveyor line 212 can enter the second transfer guide plate 242. That is to say, the second material distribution baffle 25 can switch between the third position and the fourth position. When the second material distribution baffle 25 moves to the third position (e.g., ...), ... Figure 5As shown), the second material distribution baffle 25 blocks the branch conveyor line 22, preventing the material from continuing to be conveyed along the branch conveyor line 22. At this time, under the blocking and limiting action of the second material distribution baffle 25, the material is diverted into the first transfer guide plate 241; when the second material distribution baffle 25 moves to the fourth position (as shown), Figure 6 As shown, the second dividing baffle 25 clears the branch conveyor line 22, allowing the material to continue being conveyed along the branch conveyor line 22. When the material reaches the third dividing baffle 26, the limiting action of the third dividing baffle 26 causes the material to change direction and enter the second transfer guide plate 242. It should be noted that the third dividing baffle 26 can be a fixed dividing baffle. This fixed dividing baffle is located at the position that blocks the branch conveyor line 22 and always remains in this position. When the material conveyed by the branch conveyor line 22 reaches the fixed dividing baffle, the fixed dividing baffle prevents the material from continuing to move along the branch conveyor line 22 and causes the material to change direction and enter the second transfer guide plate 242. This simplifies the structure of the third dividing baffle 26. Of course, in other embodiments, the third material distribution baffle 26 can also be a movable material distribution baffle. The third material distribution baffle 26 can switch between the fifth position and the sixth position. When the third material distribution baffle 26 is moved to the fifth position, the third material distribution baffle 26 blocks the branch conveyor line 22, so that the material cannot continue to be conveyed along the branch conveyor line 22. At this time, under the blocking and limiting action of the third material distribution baffle 26, the material is diverted to enter the second transfer guide plate 242. When the material conveyed by the branch conveyor line 22 needs to continue to be conveyed after reaching the second transfer guide plate 242, the third material distribution baffle 26 can be moved to the sixth position, so that the third material distribution baffle 26 can give way to the branch conveyor line 22, so that the material can continue to be conveyed along the branch conveyor line 22.

[0097] Therefore, this embodiment can realize the conveying of two different materials and avoid mixing of the two different materials, thus enabling mixed production of different materials. Of course, the first main conveyor line 211 and the second main conveyor line 212 can also convey the same material to improve conveying efficiency.

[0098] It should be noted that this embodiment does not limit the specific movement mode of the second material distribution baffle 25, such as... Figure 5 and Figure 6As shown, in some embodiments, a third bracket 254 is provided at the position where the branch conveyor line 22 docks with the first transfer guide plate 241. The third bracket 254 can span the branch conveyor line 22 and is equipped with a cylinder 253. The third bracket 254 is rotatably connected to a rotating shaft 255 via a bearing 251. The second material distribution baffle 25 is connected to one end of the rotating shaft 255, and the other end of the rotating shaft 255 is connected to one end of a connecting block 252. The other end of the connecting block 252 is connected to the cylinder 253, so that the cylinder 253 extends and retracts, and the connecting block 252 drives the rotating shaft 255 to rotate forward and backward, thereby causing the rotating shaft 255 to drive the second material distribution baffle 25 to switch positions. During operation, the cylinder 253 actuates, driving the connecting block 252 to drive the rotating shaft 255 to rotate around the bearing 251, thereby causing the rotating shaft 255 to drive the second material distribution baffle 25 to rotate, realizing the switching of the second material distribution baffle 25 between the third position and the fourth position. For example, as Figure 5 and Figure 6 As shown, when cylinder 253 retracts, the second material distribution baffle 25 is in the third position, blocking the branch conveyor line 22; when cylinder 253 extends, the second material distribution baffle 25 is in the fourth position, allowing the branch conveyor line 22 to pass. Furthermore, the specific movement modes of the first material distribution baffle 23 and the third material distribution baffle 26 described above can be the same as the specific movement mode of the second material distribution baffle 25, and will not be repeated here. It is understood that when the specific movement mode of the first material distribution baffle 23 is the same as that of the second material distribution baffle 25 described above, the main conveyor line 21 is provided with a third support 254 corresponding to the positions of each branch conveyor line 22. The third support 254 spans across the main conveyor line 21, and the other structures are as described above, except that the end of the rotating shaft 255 away from the connecting block 252 is connected to the first material distribution baffle 23. When the specific movement mode of the third material distribution baffle 26 is the same as that of the second material distribution baffle 25, a third bracket 254 is provided at the position where the branch conveyor line 22 and the second transfer guide plate 242 are connected. Other structures are as described above, except that the end of the rotating shaft 255 away from the connecting block 252 is connected to the third material distribution baffle 26.

[0099] It should be noted that when the first main conveyor line 211 and the second main conveyor line 212 convey different materials, in order to avoid material mixing, the first main conveyor line 211 and the second main conveyor line 212 do not simultaneously supply materials to the same branch conveyor line 22. For ease of description, the same branch conveyor line 22 is referred to as the target branch conveyor line 22. That is, when the material conveyed by the first main conveyor line 211 enters the target branch conveyor line 22, the material conveyed by the second main conveyor line 212 does not enter the target branch conveyor line 22. Similarly, when the material conveyed by the second main conveyor line 212 enters the target branch conveyor line 22, the material conveyed by the first main conveyor line 211 does not enter the target branch conveyor line 22, in order to avoid material mixing between the first main conveyor line 211 and the second main conveyor line 212. Specifically, this can be achieved by setting first material distribution baffles on the first main conveyor line 211 and the second main conveyor line 212 respectively, corresponding to the same branch conveyor line 22. 23 is used for control. For example, when the first material distribution baffle 23 of the first main conveyor line 211 blocks the first main conveyor line 211 so that the material conveyed by the first main conveyor line 211 enters the target branch conveyor line 22, then the first material distribution baffle 23 of the second main conveyor line 212 opens the second main conveyor line 212 so that the material of the second main conveyor line 212 continues to be conveyed after reaching the position of the corresponding target branch conveyor line. Similarly, when the first material distribution baffle 23 of the second main conveyor line 212 blocks the second main conveyor line 212 so that the material conveyed by the second main conveyor line 212 enters the target branch conveyor line 22, then the first material distribution baffle 23 of the first main conveyor line 211 opens the first main conveyor line 211 so that the material of the first main conveyor line 211 continues to be conveyed after reaching the position of the corresponding target branch conveyor line.

[0100] It should be noted that this embodiment does not limit the specific number of hoppers 213 at the entrance of a single main conveyor line 21. The number of hoppers 213 at the entrance of a single main conveyor line 21 can be one or at least two. In some embodiments, two hoppers 213 are provided at the entrance of a single main conveyor line 21. The two hoppers 213 are respectively located on both sides of the main conveyor line 21, and the two hoppers 213 are symmetrically arranged about the main conveyor line 21. This can realize material supply at two stations, which is beneficial to improving work efficiency.

[0101] Furthermore, in some embodiments, the hopper 213 is a funnel, and when the material is poured into the hopper 213, impurities in the material can fall out from the hole at the bottom of the funnel.

[0102] It should be noted that the above embodiments do not limit the specific structure of the soft bag cutting device 1, as long as it can open the soft bag 10.

[0103] like Figure 8 As shown, in some embodiments, the soft bag cutting device 1 includes a frame 11, at least one set of first clamping devices 12, two second clamping assemblies 13, a cutting blade 14, and a drive mechanism 15. The frame 11 mainly serves as a load-bearing unit, used to install and support the first clamping devices 12, the second clamping assemblies 13, the cutting blade 14, and the drive mechanism 15. The first clamping devices 12 are mounted on the frame 11. Each set of first clamping devices 12 includes two first clamping assemblies 121 arranged opposite each other at the same height. The two first clamping assemblies 121 in the same set are used to clamp the two sides of the top of the soft bag 10. When there are at least two sets of first clamping devices 12, the at least two sets of first clamping devices 12 are spaced apart in the vertical direction. The first clamping device 12 is positioned below the first clamping device 12 and is used to clamp the body of the soft bag 10. The cutting blade 14 is connected to the drive mechanism 15, which is located on the frame 11. When the first clamping device 12 is in one group, the cutting blade 14 is located below the height of the first clamping device 12. When the first clamping device 12 is in two groups, the cutting blade 14 is located in the gap between the heights of the two groups of first clamping devices 12. The drive mechanism 15 is used to drive the cutting blade 14 to move along the line parallel to the connection between the two first clamping devices 121 in the same group, so that the cutting blade 14 cuts open the opening of the soft bag 10.

[0104] When the first clamping components 121 are in a set, during operation, the soft bag 10 is fed into the cutting station of the soft bag cutting device 1. Then, the two first clamping components 121 in the set clamp the two sides of the top of the soft bag 10, and the two second clamping components 13 clamp the body of the soft bag 10. Thus, the soft bag 10 is positioned and clamped by the combined action of the first clamping device 12 and the two second clamping components 13. Then, the drive mechanism 15 is started, so that the drive mechanism 15 drives the cutting blade 14 to move along the line parallel to the connection between the two first clamping components 121 in the same set. Since the cutting blade 14 is located below the height of the first clamping device 12, when the cutting blade 14 moves, it horizontally cuts the soft bag 10 from below the first clamping device 12 to form a bag opening, so that the material (such as rubber stopper, aluminum cap or combination cap, etc.) inside the soft bag 10 can be poured out.

[0105] When there are two sets of first clamping components 121, during operation, the soft bag 10 is fed into the cutting station of the soft bag cutting device 1. Then, the two first clamping components 121 of one set clamp the two sides of the top of the soft bag 10 at the same height, and the two first clamping components 121 of the other set clamp the two sides of the top of the soft bag 10 at another height. That is, the two sets of first clamping devices 121 respectively clamp the two sides of the top of the soft bag 10 at two different heights, and the two second clamping components 13 clamp the bag body of the soft bag 10. Thus, the two sets of first clamping devices 121 are used to clamp the soft bag 10. Together with the two second clamping components 13, the soft bag 10 is positioned and clamped. Then, the drive mechanism 15 is activated, which drives the cutting blade 14 to move along the line parallel to the connection between the two first clamping components 121 in the same group. Since the cutting blade 14 is located in the gap between the heights of the two sets of first clamping devices 12, when the cutting blade 14 moves, it cuts the soft bag 10 between the two sets of first clamping devices 12 to form a bag opening, so that the material (such as rubber stopper, aluminum cap or combination cap, etc.) inside the soft bag 10 can be poured out. Understandably, when there are two sets of first clamping devices 12, the two sets of first clamping devices 12 work together to make the part of the top of the soft bag 10 located between the heights of the two sets of first clamping devices 12 more flat and taut, which is more conducive to the smooth cutting of the cutting blade 14. At the same time, after cutting, the upper set of first clamping devices 12 clamps the cut top material, and the lower set of first clamping devices 12 clamps the top of the cut bag body. At this time, under the combined action of the lower first clamping device 12 and the two second clamping components 13, the bag body of the soft bag 10 is in a taut state after cutting, avoiding the risk of the top of the bag body collapsing or tipping over due to the lack of clamping at the top of the bag body after cutting.

[0106] Of course, there can be three or more sets of first clamping devices 12. When there are three or more sets of first clamping devices 12, the three or more sets of first clamping devices 12 are arranged at intervals in the vertical direction. The first clamping components 121 of different sets of first clamping devices 12 clamp the two sides of the upper part of the soft bag 10 at different heights. In this case, the cutting blade 14 can be located in the gap between the uppermost set of first clamping devices 12 and the second set of first clamping devices 12 above. In this way, when the cutting blade 14 cuts open the bag opening of the soft bag 10, two or more sets of first clamping devices 12 can be used to clamp the cut bag body, providing a more stable clamping for the soft bag 10 after the bag opening is cut.

[0107] Therefore, the soft bag cutting device 1 can realize the automatic cutting function of the soft bag 10, avoiding manual cutting operation, thereby reducing reliance on people when opening the soft bag 10, reducing labor intensity, reducing labor costs, and improving work efficiency.

[0108] Furthermore, to facilitate the processing of the cut material at the top of the soft bag 10, in some embodiments, the drive mechanism 15 is connected to a control device. The control device controls the operation of the drive mechanism 15 so that the cutting blade 14 cuts from one side of the soft bag 10 to a preset distance from the other side of the soft bag 10, so that the cut material at the top of the soft bag 10 is not completely separated from the bag body. That is, when the drive mechanism 15 drives the cutting blade 14 to cut the soft bag 10, the cut material at the top of the soft bag 10 is not completely cut off from the soft bag 10, but a portion of the material remains uncut, so that the cut material at the top of the soft bag 10 is not completely separated from the bag body. At the same time, the cut portion is sufficient to allow the material inside the soft bag 10 to be poured out. In this way, after the material inside the soft bag 10 is poured out, the soft bag 10 can be discarded as a whole, avoiding separate waste processing of the cut material at the top of the soft bag 10 and the bag body of the soft bag 10.

[0109] It should be noted that the above embodiments do not limit the specific structure of the first clamping component 121, as long as the first clamping component 121 can clamp one side of the top of the soft bag 10. In addition, the above embodiments do not limit the specific structure of the second clamping component 13, as long as it can clamp the body of the soft bag 10.

[0110] Furthermore, to facilitate automatic feeding, automatic unloading, and automatic unloading of the soft bag cutting device 1, such as... Figure 9 As shown, in some embodiments, the end of the first robot 3 is provided with two opposing third clamping components 31 for clamping the two ends of the top edge of the soft bag 10 located at the positioning station; a bag receiving basket 32 ​​is used to receive the soft bag 10 after the bag opening is cut; a first vacuum suction bag assembly 33 extends into the bag receiving basket 32 ​​for suctioning the soft bag 10 that falls into the bag receiving basket 32; the first robot 3 is also used to drive the third clamping components 31 to move between the positioning station and the soft bag cutting device 1, so that the two third clamping components 31 clamp the soft bag 10 located at the positioning station. The top two ends of the soft bag 10 at the positioning station are positioned, and the third clamping assembly 31 clamps the soft bag 10 and sends it into the soft bag cutting device 1; after the soft bag 10 is cut open, the bag receiving basket 32 ​​is moved to the top of the hopper 213 and rotated, for example, by 180 degrees, so that the material in the soft bag 10 is poured onto the hopper 213. After the material is poured out, the bag receiving basket 32 ​​is moved to the top of the waste frame 102 so that the soft bag 10 falls into the waste frame 102 after the first vacuum suction bag assembly 33 removes the suction.

[0111] The positioning station refers to the station where the first robot 3 obtains the soft bag 10 containing materials. In this embodiment, the two opposing third clamping components 31 at the end of the first robot 3 automatically clamp the top two sides of the soft bag 10 containing materials. The first robot 3 moves to lift the soft bag 10 up and transfer the soft bag 10 lifted up by the third clamping components 31 to the soft bag cutting device 1, so that the soft bag cutting device 1 can automatically clamp and fix the soft bag 10 and automatically cut the bag, thereby cutting open the bag opening of the soft bag 10. When the first robot 3 moves the third clamping assembly 31 to the soft bag cutting device 1, and the two sets of first clamping devices 12 and two sets of second clamping assemblies 13 of the soft bag cutting device 1 clamp the soft bag 10 together, the first robot 3 moves the receiving basket 32 ​​to below the soft bag 10. After the cutting blade 14 completes the cutting and the two sets of first clamping devices 12 and two sets of second clamping assemblies 13 release the soft bag 10, the soft bag 10 automatically falls into the receiving basket 32 ​​by gravity. Then, the first robot 3 moves the receiving basket 32 ​​to the hopper 2. At point 13, the vacuum bag suction assembly picks up the soft bag 10 inside the bag receiving basket 32. Then, the first robot 3 rotates the bag receiving basket 32 ​​180 degrees so that the opening of the soft bag 10 faces downwards, allowing the material inside the soft bag 10 to pour from the opening into the hopper 213, whereby the material automatically slides down the hopper 213 to the material distribution conveyor line 2. Then, the first robot 3 moves the bag receiving basket 32 ​​to above the waste frame 102. At this point, the vacuum bag suction assembly breaks the vacuum, removing the suction force on the soft bag 10, causing the soft bag 10 to fall into the waste frame 102. Therefore, this embodiment can achieve automatic material grabbing of the soft bag 10, automatic feeding of the soft bag cutting device 1, automatic unloading of the soft bag cutting device 1, automatic dumping, and automatic disposal of the soft bag 10 after material dumping, further reducing manual operation and improving the degree of automation.

[0112] In addition, in order to achieve the positioning of the soft bag 10 at the positioning station, so that the third clamping component 31 can smoothly clamp the top edge of the soft bag 10, such as Figure 10As shown, in some embodiments, the soft-pack material feeding production line also includes a first roller conveyor 4, a lower bag-sorting plate 41, an upper bag-sorting rod 42, and a lifting member 44. The first roller conveyor 4 is used to convey the soft bags 10 with uncut openings to the end of the first roller conveyor 4, and the positioning station is located at the end of the first roller conveyor 4. The lower bag-sorting plate 41 is vertically and vertically disposed below the first roller conveyor 4, used to flatten the top of the downward-folded soft bags 10, and the top of the lower bag-sorting plate 41 is provided with a first air blowing hole pointing upwards, which is more conducive to flattening the top of the soft bags 10. The upper bag-sorting rod 42 spans across the... Above the first roller conveyor line 4, at the entrance of the positioning station, is a top bag plate 43 that is inclined toward the first roller conveyor line 4. The top bag plate 43 is provided with a second air blowing hole that is inclined in the opposite direction to the conveying direction of the first roller conveyor line 4. The top bag rod 42 can rotate to make way for the entrance of the positioning station. The lifting member 44 is raised and lowered below the first roller conveyor line 4. When the soft bag 10 is conveyed to the positioning station at the end of the first roller conveyor line 4, it lifts the top of the soft bag 10 so that the third clamping assembly 31 can clamp the top edge of the soft bag 10.

[0113] In other words, in this embodiment, the first roller conveyor 4 is used to transport the soft bag 10 containing materials to the positioning station. During the transport of the soft bag 10 by the first roller conveyor 4, when the soft bag 10 is transported to the preset position, the lower bag-collecting plate 41 is raised. At this time, the top of the lower bag-collecting plate 41 abuts against the side of the soft bag 10 against the first roller conveyor 4. During the continued transport of the soft bag 10, the top of the downward-folded soft bag 10 is flattened by the scraping action of the lower bag-collecting plate 41. During this process, the first air blowing hole at the top of the lower bag-collecting plate 41 blows air upward, which is more conducive to... The top of the soft bag 10, which is folded downwards, unfolds. As the soft bag 10 continues to be conveyed forward, it reaches the positioning station. At this time, the second air blowing hole of the upper bag plate 43 is tilted and blows air in the opposite direction to the conveying direction of the first roller conveyor line 4 to flatten the top of the folded soft bag 10. Then, the upper bag rod 42 rotates and moves away from the top of the first roller conveyor line 4 to make way for the entrance of the positioning station. At this time, the lifting member 44 rises and lifts the top of the soft bag 10 so that the third clamping assembly 31 comes to the positioning station and clamps the top edge of the soft bag 10.

[0114] As can be seen, in this embodiment, the lower bag-feeding plate 41 is used to flatten the top of the soft bag 10 that is folded downwards, and the second air blowing hole of the upper bag-feeding plate 43 is used to flatten the top of the soft bag 10 that is folded upwards, which serves to organize the top opening of the soft bag 10 during the conveying process. The lifting member 44 is used to lift the top of the soft bag 10, so that the third clamping component 31 can clamp the top edge of the soft bag 10.

[0115] It should be noted that in some embodiments, a position detection device 49 may be provided on the first roller conveyor line 4 to determine whether the soft bag 10 has reached the desired preset position. For example, when the soft bag 10 reaches the preset position, the lower bag sorting plate 41 is controlled to rise.

[0116] Furthermore, in order to automatically feed the first roller conveyor line 4, such as... Figure 7 As shown, in some embodiments, the flexible packaging material feeding production line further includes a flexible bag feeding station, a first support 45, a first vision inspection device 46, and a second robot. The flexible bag feeding station is located on the side of the entrance end of the first roller conveyor line 4 and is used to place the flexible bag carrier 101 containing the flexible bag 10. The first support 45 is set corresponding to the flexible bag feeding station, and the first vision inspection device 46 is movably set on the first support 45. The first vision inspection device 46 is used to detect the first flexible bag information of the flexible bag 10 on the flexible bag carrier 101. The end of the second robot is also equipped with a flexible bag picking device. The second robot is also used to drive the flexible bag picking device to pick up the flexible bag 10 on the flexible bag carrier 101 according to the first flexible bag information, and place the flexible bag 10 picked up by the flexible bag picking device to the entrance end of the first roller conveyor line 4. It should be noted that the flexible bag picking device can be a second vacuum suction bag assembly or a clamping assembly, as long as the flexible bag picking device can pick up the flexible bag 10 on the flexible bag carrier 101.

[0117] In other words, during operation, the first vision detection device 46 is moved to detect the soft bags 10 on the soft bag carrier 101 placed at the soft bag feeding station, determining the orientation and position of the soft bags 10, i.e., the first soft bag information. The first vision detection device 46 sends the first soft bag information to the second robot, causing the second robot to control its end-effector soft bag picking device to move accurately above the soft bag 10 to be picked up. The soft bag picking device then picks up the soft bag 10, and the second robot moves to place the soft bag 10 picked up by the soft bag picking device onto the first roller conveyor line 4. That is to say, the second robot has the function of automatically feeding the first roller conveyor line 4.

[0118] It should be noted that this embodiment does not limit the specific structure and detection method of the first visual detection device 46, as long as it can scan all the soft bags 10 inside the soft bag carrier 101 and confirm the first soft bag information of any one soft bag 10. In some embodiments, the first visual detection device 46 includes a 3D camera.

[0119] Furthermore, in some embodiments, a centering component 47 is provided on the first roller conveyor line 4. The centering component 47 is used to position the soft bag 10 in the middle of the first roller conveyor line 4. It should be noted that this embodiment does not limit the specific position or number of the centering component 47, as long as the centering component 47 is set on the conveying path of the soft bag 10 and can position the soft bag 10 in the middle of the first roller conveyor line 4. For example, the centering component 47 can be located at the end of the first roller conveyor line 4 to ensure that the soft bag 10 conveyed to the positioning station is in the middle of the first roller conveyor line 4, that is, the soft bag 10 is in the middle of the positioning station, which plays a limiting role for the soft bag 10, so that the soft bag 10 has a more correct position, which makes it convenient for the third clamping component 31 to clamp the top edge of the soft bag 10. Of course, in other embodiments, the first roller conveyor line 4 includes an inlet end, and a centering component 47 can also be provided at the inlet end of the first roller conveyor line 4 so that the soft bag 10 entering the first roller conveyor line 4 is located in the middle of the first roller conveyor line 4. This is beneficial for the soft bag 10 to be located in the middle of the first roller conveyor line 4 during the conveying process, and avoids the soft bag 10 from colliding with the side of the first roller conveyor line 4 during the conveying process.

[0120] It should be noted that this embodiment does not limit the specific structure of the centering component 47. In some embodiments, the centering component 47 includes two opposing limiting plates. The two limiting plates can also move relative to each other to adjust the position of the soft bag 10 passing through it, so that the soft bag 10 is centered.

[0121] In some embodiments, a spray pipe 48 is provided on the side of the first roller conveyor line 4. One end of the spray pipe 48 is connected to a spray liquid supply device to deliver the spray liquid supplied by the spray liquid supply device. The other end of the spray pipe 48 is connected to a spray head 481, which is located above and / or below the conveying path of the first roller conveyor line 4. The spray head 481 is used to spray the soft bags 10 on the first roller conveyor line 4 to clean or disinfect the soft bags 10. That is, during the conveying process of the soft bags 10 on the first roller conveyor line 4, the spray heads 481 above and / or below the first roller conveyor line 4 are used to spray the upper and lower sides of the soft bags 10 to clean or disinfect them. In some embodiments, the spray head 481 is used to spray alcohol on the upper and / or lower sides of the soft bags 10 for sterilization.

[0122] Furthermore, in order to achieve automatic turnover of the soft bags 10 containing materials from the raw material warehouse 5 to the soft bag feeding station, such as... Figure 11 As shown, in some embodiments, the flexible packaging material feeding production line also includes a raw material warehouse 5, a box unpacking, bag retrieval, and palletizing device 6, a bag material buffer position 7, an empty carrier temporary storage position 8, and an AGV trolley 9 (e.g., Figure 12As shown, the raw material warehouse 5 is equipped with a pallet for placing cartons containing soft bags 10; the unpacking and palletizing device 6 is used to unpack the cartons and remove the soft bags 10 from the cartons and load them into soft bag carriers 101; the bag material buffer position 7 is used to place the soft bag carriers 101 containing soft bags 10; the empty carrier temporary storage position 8 is used to place empty soft bag carriers 101; the AGV trolley 9 is used to transport the cartons to the unpacking and palletizing device 6, transfer the soft bag carriers 101 containing soft bags 10 to the bag material buffer position 7, transfer the soft bag carriers 101 in the bag material buffer position 7 to the soft bag feeding station, and transfer the empty soft bag carriers 101 in the soft bag feeding station to the empty carrier temporary storage position 8.

[0123] In other words, during operation, the AGV trolley 9 transports the cartons from the raw material warehouse 5 to the unpacking, bagging, and stacking device 6; the unpacking, bagging, and stacking device 6 unpacks the cartons and removes the soft bags 10 from the cartons, then loads them into the soft bag carrier 101; then, the AGV trolley 9 transfers the soft bag carrier 101 to the bag material buffer position 7, and the AGV trolley 9 transfers the soft bag carrier 101 from the bag material buffer position 7 to the soft bag feeding station. After the second robot has picked up all the soft bags 10 from the soft bag carrier 101 at the soft bag feeding station, the AGV trolley 9 transfers the empty soft bag carrier 101 at the soft bag feeding station to the empty carrier temporary storage position 8, thereby realizing the automatic turnover of soft bags 10 from the raw material warehouse 5 to the soft bag feeding station.

[0124] It should be noted that this embodiment does not limit the specific function of the unpacking, bagging, and stacking device 6, as long as it can unpack the carton and take out the soft bag 10 from the carton and put it into the soft bag carrier 101.

[0125] like Figure 12As shown, in some embodiments, the unpacking and palletizing device 6 includes a carton pallet station 61, a second support 62, a second vision inspection device 63, a carton cutter and lid remover 64, a strapping machine 65, a third robot 66, a second roller conveyor line 67, and a fourth robot 68. The carton pallet station 61 is used to place pallets that can hold cartons. The second vision inspection device 63 is movably mounted on the second support 62. The second vision inspection device 63 is used to detect the carton information of the cartons on the pallet and to detect the second soft bag information of the soft bag 10 inside the carton on the carton cutter and lid remover 64. The carton cutter and lid remover 64 is used to cut the top cover of the carton along the periphery of the top surface of the carton after the strapping of the carton is removed, and to remove the top cover. After the soft bags 10 inside the cardboard box are removed, the cardboard box is moved away. The strapping machine 65 is used to remove the cut strapping from the cardboard box. The third robot 66 is used to obtain the cardboard box from the pallet according to the cardboard box information, place the cardboard box on the box cutter and lid remover 64, and cut the strapping of the cardboard box. After the box cutter and lid remover 64 removes the lid, the soft bags 10 inside the cardboard box are placed on the second roller conveyor line 67 according to the second soft bag information. The cardboard box information here may include the spatial position information and orientation information of the cardboard box, etc. The second soft bag information here may include the position information and orientation information of the soft bag 10 inside the cardboard box, etc. In addition, the third robot 66 can obtain the cardboard box from the pallet according to the cardboard box information by using a suction cup device. The second roller conveyor line 67 is used to transport the soft bags 10. The fourth robot 68 is located at the end of the second roller conveyor line 67 and is used to load the soft bags 10 on the second roller conveyor line 67 into the soft bag carrier 101.

[0126] In other words, during operation, the AGV trolley 9 transports cartons from the raw material warehouse 5 to the carton pallet station 61 of the unpacking, bagging, and palletizing device 6. A second vision detection device 63 is used to detect the cartons at the pallet station 61 to determine their orientation, position, and the location of the packing straps—that is, the carton information. The second vision detection device 63 then sends this information to the third robot 66, which, based on this information, picks up the cartons from the pallet station 61 and places them on the box cutter / cap remover 64. The third robot 66 then cuts the packing straps on the cartons. The packing strap removal machine 65 then removes the cut packing straps from the cartons. Finally, the box cutter / cap remover... Machine 64 cuts off the top cover of the carton along the perimeter of the top surface of the carton, and the top cover is removed by the carton cutter and lid remover 64. At this time, by moving the second vision detection device 63, the direction, position and other information of the soft bag 10 in the carton on the carton cutter and lid remover 64 are detected, that is, the second soft bag information. The second vision detection device 63 sends the second soft bag information to the third robot 66. The third robot 66 obtains the soft bag 10 in the carton according to the second soft bag information and places the obtained soft bag 10 on the second roller conveyor line 67. The third robot 66 obtains the soft bag 10 in the carton by using a suction cup device to pick up the soft bag 10 in the carton, or by using a clamping device to clamp the soft bag 10 in the carton. The soft bags 10 are conveyed to the end of the second roller conveyor line 67; and the fourth robot 68 loads the soft bags 10 from the second roller conveyor line 67 into the soft bag carrier 101; during this process, after all the soft bags 10 in the carton have been removed, the carton cutter and cap remover 64 removes the carton. Therefore, this embodiment can automate the process from the carton on the pallet to the soft bags 10 in the soft bag carrier 101, including automatic carton unpacking, automatic carton transfer, automatic cutting of packing straps, automatic removal of packing straps, automatic transfer of soft bags 10, automatic transport of soft bags 10, and automatic unloading and stacking of soft bags 10. It should be noted that this embodiment does not limit the specific structure of the carton cutter and cap remover 64 and the packing strap remover 65, as long as they can achieve the corresponding functions.

[0127] It is evident that this soft packaging material feeding production line can automate the handling, unpacking, stacking, and feeding of materials packed in soft bags 10. Ultimately, it automates the intermediate process from material retrieval at the source to final material feeding, reducing manual labor intensity, lowering labor costs, and improving work efficiency. At the same time, it also reduces the harm of raw materials to the human body.
