[0032] The soft bag cutting device provided by the utility model, when the first clamping assembly is a group, when working, the soft bag is sent to the cutting station of the soft bag cutting device, and then, the two first clamping assemblies of the group are used to clamp the two sides of the top of the soft bag, and the two second clamping assemblies are used to clamp the bag body of the soft bag, so that the first clamping device and the two second clamping assemblies work together to achieve the positioning and clamping of the soft bag; then, the driving mechanism is started to drive the cutting blade to move along the direction parallel to the connecting line of the two first clamping assemblies in the same group. Since the cutting blade is located below the height of the first clamping device, when the cutting blade moves, the soft bag is horizontally cut from the bottom of the first clamping device to form a bag opening, so that the material (such as a rubber plug, an aluminum cover or a combination cover, etc.) in the soft bag can be poured out. When there are two groups of first clamping assemblies, during operation, the two first clamping assemblies of one group are used to clamp the two sides of the same height of the top of the soft bag, and the two first clamping assemblies of the other group are used to clamp the two sides of the other height of the top of the soft bag. That is to say, the two groups of first clamping devices are used to clamp the two sides of the top of the soft bag at two different heights respectively, and the two second clamping assemblies are used to clamp the bag body of the soft bag, so that the two groups of first clamping devices and the two second clamping assemblies work together to achieve the positioning and clamping of the soft bag; then, the driving mechanism is started to drive the cutting blade to move along the direction parallel to the connecting line of the two first clamping assemblies in the same group. Since the cutting blade is located in the gap between the heights of the two groups of first clamping devices, when the cutting blade moves, the soft bag is horizontally cut between the heights of the two groups of first clamping devices to form a bag opening, so that the material in the soft bag (such as a rubber plug, an aluminum cover or a combination cover, etc.) can be poured out. It can be understood that when there are two groups of first clamping devices, the two groups of first clamping devices work together so that the part of the top of the soft bag located between the heights of the two groups of first clamping devices is tightened and flatter, which is more conducive to smooth cutting by the cutting blade. At the same time, after cutting, the upper group of first clamping devices clamps the top of the cut material, and the lower group of first clamping devices clamps the top of the bag body after cutting. At this time, under the joint action of the lower first clamping device and the two second clamping components, the bag body of the soft bag after cutting is in a tensioned state, avoiding the risk of collapse or tipping over of the top of the bag body due to lack of clamping after cutting.

[0033] When there are more than three groups of first clamping devices, the more than three groups of first clamping devices are arranged at intervals in the vertical direction; the first clamping components of different groups of first clamping devices respectively clamp the two sides of the upper part of the soft bag at different heights. In this case, the cutting blade can be located in the gap between the height of the top group of first clamping devices and the second group of first clamping devices located above. In this way, after the cutting blade cuts the bag opening of the soft bag, more than two groups of first clamping devices can be used to clamp the bag body after the cut, so as to provide a more stable clamping for the soft bag after the bag opening is cut.

[0034] It can be seen that the soft bag cutting device can realize the automatic bag cutting function of the soft bag, avoiding manual bag cutting operation, thereby reducing the dependence on people when opening the soft bag, reducing manual labor intensity, reducing labor costs, and improving work efficiency.

[0035] The soft bag cutting system provided by the utility model comprises the soft bag cutting device mentioned above and has the same beneficial effects as the soft bag cutting device mentioned above. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0052] The core of the utility model is to provide a soft bag cutting device, which can reduce the dependence on people when opening soft bags, reduce the intensity of manual labor, reduce labor costs, and improve work efficiency. Another core of the utility model is to provide a soft bag cutting system including the above-mentioned soft bag cutting device, which has the same beneficial effects as the above-mentioned soft bag cutting device.

[0053] Please refer to Figure 1 , Figure 2 and Figure 3The embodiment of the utility model provides a soft bag cutting device 1, comprising a frame 11, at least one group of first clamping devices 12, two second clamping assemblies 13, a cutting blade 14 and a driving mechanism 15. The frame 11 mainly plays a bearing role and is used to install and support the first clamping device 12, the second clamping assembly 13, the cutting blade 14 and the driving mechanism 15; the first clamping device 12 is arranged on the frame 11, and each group of the first clamping device 12 includes two first clamping assemblies 121 arranged opposite to each other. The two first clamping assemblies 121 of the same group are used to clamp the two sides of the top of the soft bag 4. When there are more than two groups of the first clamping devices 12, the more than two groups of the first clamping devices 12 are arranged at intervals in the vertical direction. ; Two second clamping assemblies 13 are arranged opposite to each other and are arranged on the frame 11. The two second clamping assemblies 13 are located below the first clamping device 12 and are used to clamp the bag body of the soft bag 4; the cutting blade 14 is connected to the driving mechanism 15, and the driving mechanism 15 is arranged on the frame 11. When the first clamping device 12 is a group, the cutting blade 14 is located below the height of the first clamping device 12. When the first clamping device 12 is two groups, the cutting blade 14 is located in the gap between the heights of the two groups of first clamping devices 12. The driving mechanism 15 is used to drive the cutting blade 14 to move along a direction parallel to the connecting line of the two first clamping assemblies 121 of the same group, so that the cutting blade 14 cuts the bag mouth of the soft bag 4.

[0054] When the first clamping components 121 form a group, during operation, the soft bag 4 is fed into the cutting station of the soft bag cutting device 1, and then, two first clamping components 121 of a group are used to clamp the two sides of the top of the soft bag 4, and two second clamping components 13 are used to clamp the bag body of the soft bag 4, so that the positioning and clamping of the soft bag 4 are achieved by the joint action of a group of first clamping devices 12 and two second clamping components 13; then, the driving mechanism 15 is started, so that the driving mechanism 15 drives the cutting blade 14 to move along the direction parallel to the connecting line of the two first clamping components 121 of the same group. Since the cutting blade 14 is located below the height of the first clamping device 12, when the cutting blade 14 moves, the soft bag 4 is horizontally cut from the bottom of the first clamping device 12 to form a bag opening, so that the material (such as a rubber plug, an aluminum cover or a combination cover, etc.) in the soft bag 4 can be poured out.

[0055] When the first clamping assembly 121 is composed of two groups, during operation, Figure 2 As shown, the soft bag 4 is fed into the cutting station of the soft bag cutting device 1, and then, as shown in FIG. Figure 3As shown, two first clamping assemblies 121 of one group are used to clamp two sides of the same height of the top of the soft bag 4, and two first clamping assemblies 121 of another group are used to clamp two sides of another height of the top of the soft bag 4, that is, two groups of first clamping devices 12 are used to clamp two sides of the top of the soft bag 4 at two different heights, and two second clamping assemblies 13 are used to clamp the bag body of the soft bag 4, so that the two groups of first clamping devices 12 and the two second clamping assemblies 13 work together to achieve the positioning and clamping of the soft bag 4; then, the driving mechanism 15 is started to drive the cutting blade 14 to move along the direction parallel to the connecting line of the two first clamping assemblies 121 of the same group. Since the cutting blade 14 is located in the gap between the heights of the two groups of first clamping devices 12, when the cutting blade 14 moves, the soft bag 4 is horizontally cut between the heights of the two groups of first clamping devices 12 to form a bag opening, so that the material (such as a rubber plug, an aluminum cover or a combination cover, etc.) in the soft bag 4 can be poured out. It can be understood that when there are two groups of first clamping devices 12, the two groups of first clamping devices 12 work together so that the part of the top of the soft bag 4 located between the heights of the two groups of first clamping devices 12 is tightened and flatter, which is more conducive to smooth cutting by the cutting blade 14. At the same time, after cutting, the upper group of first clamping devices 12 clamps the top of the cut material, and the lower group of first clamping devices 12 clamps the top of the bag body after cutting. At this time, under the joint action of the lower first clamping device 12 and the two second clamping components 13, the bag body of the soft bag 4 after cutting is in a tensioned state, avoiding the risk of collapse or tipping over of the top of the bag body due to lack of clamping after cutting.

[0056] Of course, there may be more than three groups of first clamping devices 12. When there are more than three groups of first clamping devices 12, the more than three groups of first clamping devices 12 are spaced apart in the vertical direction; the first clamping components 121 of different groups of first clamping devices 12 respectively clamp the two sides of the upper part of the soft bag 10 at different heights. In this case, the cutting blade 14 may be located in the gap between the top group of first clamping devices 12 and the height of the second group of first clamping devices 12 located above. In this way, after the cutting blade 14 cuts the bag opening of the soft bag 10, more than two groups of first clamping devices 12 may be used to clamp the bag body after cutting, thereby providing a more stable clamping for the soft bag 10 after the bag opening is cut.

[0057] It can be seen that the soft bag cutting device 1 can realize the automatic bag cutting function of the soft bag 4, avoiding manual bag cutting operation, thereby reducing the dependence on people when opening the soft bag 4, reducing manual labor intensity, reducing labor costs, and improving work efficiency.

[0058] Furthermore, in order to facilitate the processing of the top cut material of the soft bag 4 after cutting, in some embodiments, the driving mechanism 15 is connected to a control device, and the control device is used to control the operation of the driving mechanism 15, so that the cutting blade 14 cuts from one side of the soft bag 4 to a preset distance from the other side of the soft bag 4, so that the top cut material of the soft bag 4 is not completely separated from the bag body. In other words, when the driving mechanism 15 drives the cutting blade 14 to cut the soft bag 4, the top cut material of the soft bag 4 is not completely cut off from the soft bag 4, but a part of the remaining material is not cut, so that the top cut material of the soft bag 4 is not completely separated from the bag body of the soft bag 4, and the cut part is sufficient to allow the material in the soft bag 4 to be poured out. In this way, after the material in the soft bag 4 is poured out, the soft bag 4 can be discarded as a whole, avoiding the waste treatment of the top cut material of the soft bag 4 and the bag body of the soft bag 4 separately.

[0059] In addition, the above embodiment does not limit the specific structure of the first clamping assembly 121, as long as the first clamping assembly 121 can clamp one side of the top of the soft bag 4. In some embodiments, a single first clamping assembly 121 includes two openable and closable clamping claws, so as to clamp two opposite faces on one side of the soft bag 4 with the two clamping claws. That is to say, the present embodiment uses two clamping claws to clamp two opposite faces on one side of the soft bag 4, which has a simple structure and is convenient for clamping. It can be understood that the two first clamping assemblies 121 in the same group clamp the opposite faces at the corresponding positions on both sides of the soft bag 4 at the same time, which is equivalent to fixing the two points on the top of the soft bag 4, so that the soft bag 4 is naturally suspended under the gravity of the material therein; when the first clamping device 12 is two groups, the four first clamping assemblies 121 of the two groups of first clamping devices 12 are used to clamp the four positions on both sides of the top of the soft bag 4 respectively, so that the soft bag 4 is naturally suspended, and under the clamping force of the four first clamping assemblies 121, the top of the soft bag 4 is flat, which is conducive to cutting the top of the soft bag 4.

[0060] It should be noted that the present embodiment does not specifically limit the action implementation method of the clamping jaws, as long as the clamping jaws can be opened and closed to clamp the two opposing surfaces on one side of the top of the soft bag 4 or release the soft bag 4. For example, in some embodiments, the clamping jaws are connected to the first cylinder, and the first cylinder drives the clamping jaws to move.

[0061] In addition, the above embodiment does not limit the specific structure of the second clamping assembly 13, as long as it can clamp the bag body of the soft bag 4. Figure 2In some embodiments, a single second clamping assembly 13 includes an abutment plate 131 for abutting against the side of the bag body, and bent edges 132 are respectively provided at both ends of the abutment plate 131. The bent edges 132 face the side where the other second clamping assembly 13 is located, and the edges 132 are used to gather the material in the soft bag 4. That is to say, the present embodiment utilizes two second clamping components 13 to respectively press against the bag body from both sides of the bag body, thereby realizing clamping of the bag body; when the bag body is clamped, the abutment plate 131 presses against the side of the bag body, and at the same time, the baffles at both ends of the abutment plate 131 have a limiting effect on the bag body at the side of the bag body, and the baffles at both ends of the abutment plate 131 are utilized to gather the material in the soft bag 4, to avoid excessive squeezing of the material in the soft bag 4 in a direction perpendicular to the connecting line of the two second clamping components 13 when the abutment plate 131 presses against the side of the soft bag 4, and the two second clamping components 13 fail to clamp the bag body tightly or the clamping is unstable, which is beneficial to improving the stability of positioning and fixing the bag body.

[0062] It should be noted that the specific implementation method of the abutment plate 131 is not limited in this embodiment, as long as the abutment plate 131 can be moved close to or away from the bag body of the soft bag 4 so that the two second clamping assemblies 13 can clamp the bag body. In some embodiments, the abutment plate 131 is connected to the second cylinder, and the abutment plate 131 is driven by the second cylinder to move.

[0063] In addition, the above embodiment does not limit the specific structure of the rack 11, as long as the rack 11 can play a bearing role. In some embodiments, the rack 11 is a frame structure.

[0064] In addition, the above embodiment does not limit the specific structure of the driving mechanism 15, as long as the driving mechanism 15 can drive the cutting blade 14 to move along a direction parallel to the connecting line of the two first clamping components 121 in the same group. In some embodiments, the driving mechanism 15 includes a moving module or a third cylinder. Further, in order to facilitate the structural layout, as shown in FIG. Figure 4 As shown, in some embodiments, the cutting blade 14 is connected to the driving mechanism 15 through a blade mounting frame 16. In addition, in some embodiments, the driving mechanism 15 is connected to the frame 11 through a first mounting plate 17.

[0065] Please refer to Figure 5 In addition to the above-mentioned soft bag cutting device 1, the utility model also provides a soft bag cutting system including the soft bag cutting device 1 disclosed in the above-mentioned embodiment, and the soft bag cutting system also includes a robot 2, and two oppositely arranged third clamping components 21 are provided at the end of the robot 2. The robot 2 is used to drive the third clamping components 21 to move between the positioning station and the soft bag cutting device 1, so that the two third clamping components 21 clamp the two ends of the top edge of the soft bag 4 located at the positioning station, and the third clamping components 21 send the clamped soft bag 4 into the soft bag cutting device 1.

[0066] It should be noted that, in the embodiment of the utility model, the positioning station refers to the station where the robot 2 obtains the soft bag 4 containing the material, which is used to place the soft bag 4 to be opened and position the soft bag 4 at the position. In this embodiment, two third clamping assemblies 21 arranged opposite to each other at the end of the robot 2 are used to automatically clamp the two sides of the top edge of the soft bag 4 containing the material, and the robot 2 is used to move the third clamping assembly 21 to lift the soft bag 4, and the soft bag 4 lifted by the third clamping assembly 21 is transferred to the above-mentioned soft bag cutting device 1, so that the above-mentioned soft bag cutting device 1 can automatically clamp and fix the soft bag 4 and automatically cut the bag, thereby cutting the bag opening of the soft bag 4. In other words, the robot 2 sends the soft bag 4 to the cutting station of the soft bag cutting device 1, and at this time, the two sets of first clamping devices 12 and the two second clamping assemblies 13 work together to automatically clamp the soft bag 4, so that the cutting blade 14 can automatically cut the soft bag 4 and cut the bag opening of the soft bag 4. It can be seen that this embodiment can realize automatic grabbing and loading of the soft bag 4, further reducing manual operations.

[0067] This embodiment does not limit the specific structure of the robot 2. In some embodiments, the robot 2 is a six-axis robot. In addition, this embodiment does not limit the specific structure of the third clamping assembly 21, as long as it can clamp the top edge of the soft bag 4. In some embodiments, the structure of the third clamping assembly 21 is the same as that of the first clamping assembly 121, which will not be repeated here.

[0068] Further, after the opening of the soft bag 4 is cut, in order to realize the automatic pouring of the material in the soft bag 4 and the automatic processing of the soft bag 4 after the material is poured out, please refer to Figure 6 and Figure 7 In some embodiments, a bag receiving basket 22 and a vacuum bag suction assembly 23 are further provided at the end of the robot 2. The bag receiving basket 22 is used to receive the soft bag 4 after the bag opening is cut; the vacuum bag suction assembly 23 extends into the bag receiving basket 22 to suck the soft bag 4 that falls into the bag receiving basket 22; the robot 2 is also used to drive the bag receiving basket 22 to move to receive the soft bag 4, and drive the bag receiving basket 22 to move to a first designated position, and drive the bag receiving basket 22 to rotate at the first designated position to pour out the material in the soft bag 4 from the bag opening, and after pouring out the material, drive the bag receiving basket 22 to move to a second designated position, so that the soft bag 4 falls into the second designated position after the vacuum bag suction assembly 23 removes the suction.

[0069] During operation, when the robot 2 drives the third clamping assembly 21 to move to the soft bag cutting device 1, so that the two groups of first clamping devices 12 and the two second clamping assemblies 13 of the soft bag cutting device 1 clamp the soft bag 4 together, the robot 2 drives the bag receiving basket 22 to move to the bottom of the soft bag 4, so that after the cutting blade 14 completes the bag cutting and the first clamping device 12 and the second clamping assembly 13 release the soft bag 4, the soft bag 4 automatically falls into the bag receiving basket 22 by gravity. At this time, the robot 2 drives the bag receiving basket 22 to move The robot 2 moves to the material pouring position, that is, the first designated position. At this time, the vacuum bag suction component 23 sucks the soft bag 4 in the bag receiving basket 22. Then, the robot 2 drives the bag receiving basket 22 to rotate, for example, rotates 180 degrees, so that the bag opening of the soft bag 4 faces downward, so that the material in the soft bag 4 is poured from the bag opening into the first designated position; then, the robot 2 drives the bag receiving basket 22 to move to the second designated position. At this time, the vacuum bag suction component 23 breaks the vacuum and removes the suction on the soft bag 4, so that the soft bag 4 falls into the second designated position.

[0070] In some embodiments, a waste frame is provided at the second designated position to receive the soft bag 4 after the material is poured out. That is, when the robot 2 drives the bag receiving basket 22 to move to the second designated position and the vacuum bag suction assembly 23 breaks the vacuum, the soft bag 4 falls into the waste frame, and the waste frame is used to collect multiple soft bags 4 so as to centrally process the waste of the soft bags 4 after the material is poured out.

[0071] To facilitate installation, Figure 7 As shown, in some embodiments, a second mounting plate 24 is provided at the end of the robot 2 , and the third clamping assembly 21 , the bag receiving basket 22 and the vacuum bag suction assembly 23 are all provided on the second mounting plate 24 .

[0072] In addition, in order to realize the positioning of the soft bag 4 at the positioning station, so that the third clamping assembly 21 can smoothly clamp the top edge of the soft bag 4, please refer to Figure 8 and Fig. 9In some embodiments, the soft bag cutting system further comprises a roller conveyor line 3, a lower bag sorting plate 31, an upper bag sorting rod 32 and a lifting member 34. The roller conveyor line 3 is used to convey the soft bags 4 whose bag openings have not been cut to the end of the roller conveyor line 3, and the positioning station is located at the end of the roller conveyor line 3; the lower bag sorting plate 31 is movably arranged below the roller conveyor line 3, and is used to flatten the top of the folded soft bag 4. The top of the lower bag sorting plate 31 is provided with a first blowing hole for blowing upwards, which is more conducive to flattening the top of the soft bag 4; the upper bag sorting rod 32 spans across the roller conveyor Above the roller conveyor line 3, at the entrance of the positioning station, an upper bag sorting plate 33 is connected which is inclined toward the roller conveyor line 3, the upper bag sorting plate 33 is provided with a second blowing hole which blows air in a direction opposite to the conveying direction of the roller conveyor line 3, and the upper bag sorting rod 32 can be rotated to make way for the position of the entrance of the positioning station; a lifting member 34 is liftably arranged below the roller conveyor line 3, and is used to lift the top of the soft bag 4 when the soft bag 4 is conveyed to the end of the roller conveyor line 3, that is, the positioning station, so that the third clamping assembly 21 can clamp the top edge of the soft bag 4.

[0073] That is to say, the present embodiment utilizes the roller conveyor line 3 to convey the soft bag 4 containing the material to the positioning station. During the process of conveying the soft bag 4 by the roller conveyor line 3, when the soft bag 4 is conveyed to the preset position, the lower bag sorting plate 31 is raised. At this time, the top of the lower bag sorting plate 31 abuts against the side of the soft bag 4 that is in contact with the roller conveyor line 3. During the continuous conveying of the soft bag 4, the top of the folded soft bag 4 is flattened under the scraping action of the lower bag sorting plate 31. In this process, the first blowing hole at the top of the lower bag sorting plate 31 blows air upward, which is more conducive to The folded-down top of the soft bag 4 unfolds; as the soft bag 4 continues to be conveyed forward, the soft bag 4 reaches the positioning station. At this time, the second blowing hole of the upper bag sorting plate 33 is tilted to blow in the direction opposite to the conveying direction of the roller conveyor line 3 to flatten the top of the folded-up soft bag 4; then, the upper bag sorting rod 32 rotates and turns away from the top of the roller conveyor line 3 to make way for the entrance of the positioning station; at this time, the lifting member 34 rises to lift the top of the soft bag 4, so that the third clamping assembly 21 comes to the positioning station and clamps the top edge of the soft bag 4.

[0074] It can be seen that the present embodiment utilizes the lower bag sorting plate 31 to flatten the downwardly folded top of the soft bag 4, and utilizes the second blowing hole of the upper bag sorting plate 33 to flatten the upwardly folded top of the soft bag 4, thereby playing the function of arranging the top bag opening of the soft bag 4 during the conveying process of the soft bag 4, and utilizes the lifting member 34 to lift up the top of the soft bag 4, so that the third clamping assembly 21 can clamp the top edge of the soft bag 4.

[0075] It should be noted that, in some embodiments, a position detection device 38 may be provided on the roller conveyor line 3 to determine whether the soft bag 4 has reached the desired preset position. For example, when the soft bag 4 reaches the preset position, the lower bag sorting plate 31 is controlled to rise.

[0076] Furthermore, if Figure 8 As shown, in some embodiments, a centering component is provided on the roller conveyor line 3, and the centering component is used to make the soft bag 4 be located in the middle position of the roller conveyor line 3. It should be noted that the present embodiment does not limit the specific position and quantity of the centering component, as long as the centering component is arranged on the conveying path of the soft bag 4, the soft bag 4 can be located in the middle position on the roller conveyor line 3. For example, in some embodiments, the centering component includes a first centering component 35, and the first centering component 35 is arranged at the end of the roller conveyor line 3, corresponding to the positioning station, and is used to make the soft bag 4 entering the end of the roller conveyor line 3 be located in the middle position of the roller conveyor line 3. That is to say, the present embodiment ensures that the soft bag 4 transported to the positioning station is in the middle position of the roller conveyor line 3 through the first centering component 35, that is, the soft bag 4 is located in the middle position of the positioning station, which plays a role in limiting the soft bag 4, so that the soft bag 4 has a more correct position, and it is convenient for the third clamping component 21 to clamp the top edge of the soft bag 4. In other embodiments, the centering component also includes a second centering component 36, and the roller conveyor line 3 includes an inlet end. The second centering component 36 is arranged at the inlet end of the roller conveyor line 3, and is used to make the soft bag 4 entering the roller conveyor line 3 be located in the middle position of the roller conveyor line 3; in this embodiment, by setting the second centering component 36, the soft bag 4 entering the roller conveyor line 3 is located in the middle position of the roller conveyor line 3, which is beneficial for the soft bag 4 to be located in the middle position of the roller conveyor line 3 during the conveying process, and to avoid the soft bag 4 from colliding with the side of the roller conveyor line 3 during the conveying process.

[0077] It should be noted that the present embodiment does not limit the specific structure of the first centering component 35 and the second centering component 36. In some embodiments, the first centering component 35 and the second centering component 36 have the same structure, and both include two relatively disposed limit plates. The two limit plates can also move relative to each other to adjust the position of the soft bag 4 passing therethrough so as to center the soft bag 4.

[0078] In addition, please continue to refer to Figure 8 In some embodiments, a spray pipe 37 is provided on the side of the roller conveyor line 3. One end of the spray pipe 37 is used to connect with a spray liquid supply device to convey the spray liquid supplied by the spray liquid supply device.
