[0001] The present application relates to the field of material packaging, and more specifically, to a material bag separation mechanism, a material bag separation device, and a bag supply machine. Background Art

[0002] Currently, fully automatic packaging machines use bag feeders to automatically supply bags, improving automation and packaging efficiency. These machines remove bags individually from a stack of bags and then supply them. However, static electricity can cause stacked bags to stick together, causing the bag feeder to remove more bags than necessary, impacting other subsequent processes.

[0003] Therefore, how to improve the problem of bag adhesion becomes a technical problem that needs to be solved in this application.

[0004] Summary of the Invention

[0005] In view of this, the present application proposes a material bag separation mechanism to improve adhesion during bag retrieval, thereby increasing the success rate of bag retrieval, bag supply and packaging.

[0006] The present application provides a material bag separation mechanism, wherein the material bag separation mechanism includes a separator, a separator mounting seat and a separator fixing seat, the separator is used to separate adjacent stacked material bags and is installed on the separator mounting seat, and the separator mounting seat can be lifted and lowered on the separator fixing seat.

[0007] The present application also provides a material bag separation device, wherein the material bag separation device includes the material bag separation mechanism and the bag taking mechanism of the present application.

[0008] The present application also provides a bag feeding machine, wherein the bag feeding machine includes the material bag separation device of the present application and a bag position mechanism arranged adjacent to the material bag separation device, and the bag taking mechanism is arranged to be able to move the material bag above the bag position mechanism.

[0009] According to the technical solution of the present application, the separator can separate adjacent stacked material bags to overcome adhesion caused by static electricity. The separator can be raised and lowered relative to the stack of material bags via a separator mounting base, so that the height can be adjusted as the height decreases as the material bag is removed, ensuring that the separator is always at the appropriate height for the material bag to be removed, thereby fully separating the material bag to be removed.

[0025] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with the implementation methods.

[0026] According to one aspect of the present application, a material bag separation mechanism is provided, wherein the material bag separation mechanism 100 includes a separator 110, a separator mounting seat 120 and a separator fixing seat 130, the separator 110 is used to separate adjacent stacked material bags and is installed on the separator mounting seat 120, and the separator mounting seat 120 can be installed on the separator fixing seat 130 in a liftable manner.

[0027] Using the material bag separation mechanism of the present application, the separator 110 can separate adjacent stacked material bags P to overcome adhesion caused by static electricity. The separator 110 can be raised and lowered relative to the stack of material bags via the separator mounting base 120, allowing the height of the separator 110 to be adjusted as the height decreases as the material bag is removed, ensuring that the separator 110 is always at the appropriate height for the material bag P currently being removed, thereby fully separating the material bag P to be removed.

[0028] The separator 110 may be in an appropriate form, for example, may include a brush, so that the bristles of the brush can be inserted between adjacent material bags P to overcome static electricity and peel off the adjacent material bags P.

[0029] To facilitate the lifting and lowering of the separator mounting base 120 relative to the separator fixing base 130, corresponding lifting guide structures can be provided on both. For example, one of the separator fixing base 130 and the separator mounting base 120 can be provided with a slide groove 131, and the other can be slidably disposed in the slide groove 131. For example, in the embodiment shown in Figure 7, the slide groove 131 is provided on the separator fixing base 130, and the separator mounting base 120 can be provided with a slider portion that cooperates with the slide groove 131.

[0030] To raise and lower the separator mounting base 120 relative to the separator fixing base 130, the material bag separating mechanism 100 may include a driving unit for driving the separator mounting base 120 to move along the slide groove 131. Specifically, the slide groove 131 may be a linear groove arranged along the height direction, and the driving unit may be configured in an appropriate form to drive the separator mounting base 120 to move linearly.

[0031] The drive unit can be controlled in an appropriate manner to adjust the position of the separator mounting seat 120 according to the needs of the bag removal operation to adapt to the height of the current material bag stack and ensure that the separator 110 can act on the topmost material bag to be removed. Specifically, the range of movement and movement of the separator mounting seat 120 can be reasonably set so that at least a portion of the separator 110 (i.e., any portion between the upper and lower edges of the separator 110) can act on the material bag to be removed. For example, the separator mounting seat 120 can be initially located at the highest position. When the height of the material bag stack is reduced by bag removal, the separator mounting seat 120 is lowered so that at least a portion of the separator 110 can act at the height of the material bag to be removed. Alternatively, the separator mounting seat 120 can be initially located at the lowest position. When the bag is removed, the separator mounting seat 120 can be raised so that at least a portion of the separator 110 can act at the height of the material bag to be removed.

[0032] According to another aspect of the present application, a material bag separation device is provided, wherein the material bag separation device includes the material bag separation mechanism 100 and the bag taking mechanism 200 of the present application.

[0033] In order to lift and lower the separator mounting base 120 relative to the separator fixing base 130, the material bag separation mechanism 100 may include a driving unit for driving the separator mounting base 120 to lift and lower. Specifically, the driving unit may be configured in an appropriate form to drive the separator mounting base 120 to move linearly in the height direction.

[0034] The bag retrieval mechanism 200 can be configured to retrieve bags from the stack of bags one by one from top to bottom. Specifically, the bag retrieval mechanism 200 can be raised or lowered to perform the bag retrieval operation. As will be appreciated, as the bag retrieval operation progresses, the height of the stack of bags gradually decreases, necessitating corresponding adjustment of the height of the separator 110. Therefore, the raising and lowering of the bag retrieval operation can be linked to the height adjustment of the separator 110. Preferably, the bag retrieval mechanism 200 includes a liftable suction cup portion 210 comprising a suction cup 211 and a ramming rod 212. The raising and lowering of the ramming rod 212 is linked to the driving unit. Specifically, as the bag retrieval operation progresses, the height of the stack of bags decreases. The ramming rod 212 can activate the driving unit, causing the driving unit to move the separator mounting base 120 to match the height of the current bag P to be retrieved, enabling the separator 110 to engage the bag P to be retrieved (i.e., position the bag P between the upper and lower edges of the separator 110), facilitating separation during bag retrieval.

[0035] In addition, preferably, when the separator 120 is used to separate adjacent material bags P, the separator 120 can be moved downward relative to the upper material bag P to achieve a better peeling effect. To this end, the driving portion may include an elastic member 140 acting on the separator mounting seat 120 and a driving unit 150 connected to the separator mounting seat 120 to overcome the elastic force of the elastic member and drive the separator mounting seat 120 to move. The descent of the ramming rod 212 can actuate the driving unit 150 to drive the separator mounting seat 120 to move upward, so that the separator 110 can act on the material bag to be taken. The elastic force of the elastic member 140 is set to cause the separator mounting seat 120 to move downward when the ramming rod 212 rises. That is, when the tamping rod 212 moves downward, it activates the bag taking unit 150, so that the separator mounting seat 120 drives the separator 110 to overcome the action of the elastic member 140 and move upward to the position corresponding to the material bag to be taken. When the suction cup 211 sucks the material bag P and moves upward, the tamping rod 212 moves upward accordingly, and the separator mounting seat 120 moves downward under the elastic force of the elastic member 140, so that the separator 110 and the action of the suction cup 211 sucking the material bag P and taking the bag upward produce movements in opposite directions, thereby improving the peeling effect and success rate.

[0036] The elastic member 140 can be configured in an appropriate form to provide the required elastic force. Specifically, as shown in Figures 7 to 9, the elastic member 140 can be a tension spring, one end of which can be fixed to the bottom of the separator fixing base 130 and the other end can be connected to the bottom of the separator mounting base 120, thereby always providing downward tension to the separator mounting base 120.

[0037] The driving unit 150 can be configured to move the separator mounting seat 120 upward by the descent of the ramming rod 212. In the embodiment shown in Figures 7 and 8, the driving unit 150 can include a transmission belt 151, a guide wheel 152, and a slider 153 capable of being raised and lowered relative to the separator mounting seat 130. The guide wheel 152 is rotatably mounted on the top of the separator mounting seat 130. The transmission belt 151 is arranged to pass through the guide wheel 152 and has its two ends connected to the separator mounting seat 120 and the slider 153, respectively. The ramming rod 212 can move to engage with the slider 153 and drive the slider 153 to overcome the elastic force and move. Specifically, when the suction cup portion 120 descends, the ramming rod 212 descends and abuts the slider 153 through the lower end of the ramming rod 212, causing the slider 153 to move downward, and then driving the separator mounting seat 120 upward through the transmission belt 151.

[0038] In the present application, in order to facilitate control and extend the service life of the material bag separation mechanism 100 (for example, to avoid frequent changes in the degree of expansion and contraction of the elastic member 140), it can be configured so that the slider 153 is always pushed by the ram 212 to slide the same distance, that is, the separator 110 is always raised to the same highest position. It is understood that to ensure that it can act on the material bag to be removed, the height from the upper edge to the lower edge of the separator 110 should be no less than half the highest height of the material bag stack, so that the height of any material bag to be removed is between the lower edge of the separator 110 when it is in the lowest position (i.e., not driven upward by the slider 153) and the upper edge of the separator 110 when it is in the highest position (i.e., the highest position driven upward by the slider 153). For example, the upper edge of the separator 110 can reach the highest height of the material bag stack when it is in the highest position. In this case, when the material bag stack is high, when the separator 110 is in the highest position, at least the portion near the upper edge of the separator 110 can act on the material bag to be taken and can move downward relative to the material bag to be taken when taking the bag so that the material bag basically passes through the entire separator 110; when the material bag stack is low, the separator 110 can move downward relative to the material bag to be taken when taking the bag so that the material bag basically passes through the entire separator 110.

[0039] In this case, it is understandable that as the material bags are taken from the stack, the height of the top material bag gradually decreases, and the stroke of the tamping rod 212 will decrease. In order to avoid damage to the tamping rod 212, the stroke of the tamping rod 212 can be made variable. For example, the tamping rod 212 can be configured to be retractable. Preferably, as shown in Figure 11, the suction cup portion 210 includes a mounting bracket 213 and a compression spring 214, the suction cup 211 is mounted on the mounting bracket 213, and the mounting bracket 213 is provided with a slide arranged along the lifting direction of the suction cup portion 210, the tamping rod 212 is slidably matched with the slide, and the compression spring 214 is compressed between the mounting bracket 213 and the tamping rod 212 to provide a downward force to the tamping rod 212. Specifically, the slideway can be a vertical through-hole provided on the mounting frame 213, through which the tamping rod 212 is inserted. A boss can be provided at the bottom of the tamping rod 212, and a compression spring 214 can be provided around the tamping rod 212. The two ends of the compression spring 214 can respectively abut the bottom edge of the through-hole and the boss of the mounting frame 213. Thus, as the height of the material bag stack decreases, the distance that the tamping rod 212 extends downward from the through-hole decreases.

[0040] Furthermore, the provision of the compression spring 214 can prevent damage to the ram 212 caused by excessive reaction force. The compression spring 214 can be configured to have a hardness slightly greater than that of the elastic member 140, thereby supporting the ram 212 to extend a greater distance out of the through hole and actuate the slider 153 when the stack height of the material bags is high.

[0041] To facilitate bag removal from multiple stacks of material bags, preferably, as shown in Figures 1 to 5 , the material separation device may include a conveyor belt 300. The material bag separation mechanism 100 includes a first material bag separation mechanism 100a fixed adjacent to one end of the conveyor belt 300 and a second material bag separation mechanism 100b disposed on the conveyor belt 300. The bag removal mechanism 200 is disposed above the one end of the conveyor belt 300 and includes a ramming rod 212 capable of driving the first and second material bag separation mechanisms 100a, 100b, respectively. The material separation device includes a plurality of second material bag separation mechanisms 100b disposed at intervals on the conveyor belt 300. Thus, material bags can be separated at both side edges by the first and second material bag separation mechanisms 100a, 100b, respectively.

[0042] Multiple stacks of material bags can be positioned roughly between two adjacent second bag separation mechanisms 100b. When a bag needs to be removed from a stack, the stack can be conveyed to the one end of the conveyor belt 300 via the conveyor belt 300, so that one side of the stack is positioned by the first bag separation mechanism 100a and the other side is positioned by the second bag separation mechanism 100b, thereby cooperating with the bag removal mechanism 200 for bag removal. When a bag is removed from a stack of material bags, the adjacent stack of material bags downstream in the conveying direction can be conveyed to the one end of the conveyor belt 300 via the conveyor belt 300 for bag removal.

[0043] To accommodate material bags of different specifications, the position of the tamping rod 212 is preferably configured to be adjustable along the conveying direction of the conveyor belt 300. For example, in the embodiment shown in FIG11 , the mounting frame 213 may include a main body 2131 and a bracket 2132. The suction cup 211 is mounted on the main body 2131, and the tamping rod 212 is mounted on the bracket 2132. One of the main body 2131 and the bracket 2132 may be provided with a plurality of mounting holes arranged along the conveying direction, and the other may be provided with assembly holes corresponding to the mounting holes. Thus, the bracket 2132 and the tamping rod 212 can be positioned relative to the main body 2131 by aligning the appropriate mounting holes with the assembly holes and mounting them with fasteners.

[0044] In addition, preferably, multiple first bag separation mechanisms 100a and multiple second bag separation mechanisms 100b can be arranged transversely to the conveying direction of the conveyor belt 300. That is, as shown in Figures 1, 4, 5, and 6, multiple groups of second bag separation mechanisms 100b are arranged along the transmission direction, and each group of second bag separation mechanisms 100b is provided transversely to the conveying direction. When removing a bag, the two sides of the bag to be removed are separated by the multiple first bag separation mechanisms 100a and multiple second bag separation mechanisms 100b, respectively.

[0045] Accordingly, the suction cup portion 210 may include two rows of tamping rods 212 corresponding to the plurality of first material bag separation mechanisms 100a and the plurality of second material bag separation mechanisms 100b. In addition, to provide balanced and stable adsorption of the material bags to be taken, the suction cup portion 210 may include a plurality of suction cups 211. The plurality of suction cups 211 may be evenly arranged in rows and columns to adsorb different parts of the surface of the material bags. Specifically, the suction cups 211 may be disposed on the lower side of the main body 2131. The main body 2131 may be provided with an exhaust pipe 214 connected to the suction cups 211. A guide sleeve 215 may be provided on the upper side of the main body 2131 around the exhaust pipe 214. A suction cup compression spring 216 may be provided between the inner hole of the guide sleeve 215 and the outer circle of the exhaust pipe 214.

[0046] To facilitate precise positioning of the material bag and improve bag retrieval accuracy and success rate, the material separation device preferably includes a baffle for positioning the material bag relative to the material bag separation mechanism 100, and the separation member 110 extends beyond the surface of the baffle to contact the material bag. The baffle and the corresponding material bag separation mechanism 100 maintain a relatively fixed positional relationship. Specifically, as shown in FIG1 , the material separation device includes a first baffle P1 corresponding to the first material bag separation mechanism 100a and a second baffle P2 corresponding to the second material bag separation mechanism 100b. The distance between the first baffle P1 and the second baffle P2 can be consistent with the width of the material bag (the positions of the first baffle P1 and the second baffle P2 can be adjustable to accommodate material bags of different sizes). The distance between the separator mounting bases 120 of the first material bag separation mechanism 100a and the second material bag separation mechanism 100b can be greater than the width of the material bag, and the distance between the front ends (i.e., the ends that act on the material bag) of the separators 110 of the first material bag separation mechanism 100a and the second material bag separation mechanism 100b can be less than the width of the material bag. For example, the separator 110 is a brush, the base of the brush being connected to the separator mounting base 120, and the tip of the brush being the front end of the separator 110, which can extend between the material bags.

[0047] To balance the positioning function of the baffles with the separation function of the bag separation mechanism 100 and to prevent interference between the separation element 110 and the baffles, the baffles and corresponding bag separation mechanisms 100 are preferably arranged alternately transversely to the conveying direction. Specifically, the conveyor belt 300 may be provided with multiple conveyor belt sections 310 arranged side by side. Each of the conveyor belt sections 310 may be driven by a common drive unit 320 (comprising a drive shaft 321 and a pulley 322 driven by the drive shaft 321). The second baffles P2 and the second bag separation mechanism 100b may be alternately arranged on the multiple conveyor belt sections 310. As shown in Figures 1 and 4 to 6, five conveyor belt sections 310 are arranged in sequence. The second bag separation mechanism 100b is respectively provided on the first, third, and fifth conveyor belt sections 310, while the second baffles P2 are provided on the second and fourth conveyor belt sections 310. The first bag separation mechanism 100a is arranged corresponding to the second bag separation mechanism 100b along the conveying direction, and the first baffle P1 is arranged corresponding to the second baffle P2 along the conveying direction.

[0048] According to another aspect of the present application, a bag supply machine is also provided, wherein the bag supply machine includes the material bag separation device of the present application and a bag position mechanism 400 arranged adjacent to the material bag separation device, and the bag taking mechanism 200 is configured to be able to move the material bag to above the bag position mechanism 400.

[0049] During use, after the bag taking mechanism 200 takes a bag from the material bag stack, it can move the material bag to above the bag position mechanism 400 and place the material bag at the bag position mechanism 400, thereby completing the bag supply.

[0050] The bag positioning mechanism 400 and the material bag separation device can be arranged along the conveying direction of the conveyor belt 300. For example, the bag positioning mechanism 400 and the conveyor belt 300 can be arranged on both sides of the first material bag separation mechanism 100a along the conveying direction. The bag retrieval mechanism 200 can be configured to move the suction cup portion 210 along the conveying direction to place the material bag on the bag positioning mechanism 400. Specifically, the bag retrieval mechanism 200 can include a bag transfer device 220 and a lifting device 230 for lifting and lowering the suction cup portion 210. The bag transfer device 220 includes a fixing plate 221 for fixing to a mounting base (e.g., a crossbeam 540 of the frame 500 described below), a slide rail 222 mounted on the fixing plate 221, a slider 223 slidably engaged with the slide rail 222, a mounting frame 224 for connecting the slider 223 to the lifting device 230, and a moving unit 225 (e.g., a cylinder) for driving the slider 223. The moving unit 225 drives the slider 223 to move along the slide rail 222 between a bag removal position located above one end of the conveyor belt 300 and a bag supply position located above the bag positioning mechanism 400. This allows the slider 223 to move the bag to the supply position after the bag is removed from the bag removal position, and then return to the bag removal position after the bag is supplied to remove another bag. The lifting device 230 can be in any suitable form, such as a pneumatic cylinder. The lifting device 230 can be connected to the main body 2131 to drive the suction cup 211 and the tamping rod 212 to rise and fall via the lifting body 2131.

[0051] To facilitate positioning of the material bag, as shown in Figure 12, the bag positioning mechanism 400 may include positioning plates 410 for positioning the material bag relative to each other. To facilitate positioning of material bags of different specifications, the distance between the positioning plates 410 is adjustable. Specifically, the bag positioning mechanism 400 may include a screw 401, a left-handed nut seat 402, a right-handed nut seat 403, and a driving unit for driving the screw 401. The screw 401 is provided with threads of opposite rotation directions on both sides, and the left-handed nut seat 402 and the right-handed nut seat 403 are respectively provided on the threads on both sides of the screw 401. Two positioning plates 410 are respectively installed on the left-handed nut seat 402 and the right-handed nut seat 403 so that they can move closer to or farther away from each other when the driving unit drives the screw 401 to rotate. The driving unit can adopt an appropriate form to drive the screw 401 to rotate forward and backward. For example, the driving unit may include a motor 404, a driving wheel 405, a pulley 406, and a transmission belt 407. The motor 404 drives the driving wheel 405, the pulley 406 is fixed to the middle of the screw 401, and the pulley 405 and the driving wheel 405 are driven by the transmission belt 407. In addition, to guide the positioning plates 410 to move toward or away from each other, the bag positioning mechanism 400 may also include a positioning plate guide rail 408 and two positioning plate sliders 409 that slidably cooperate with the positioning plate guide rail 408. The left-handed nut seat 402 and the right-handed nut seat 403 are respectively mounted on the two positioning plate sliders 409.

[0052] The bag feeding machine of the present application may include a frame 500, which serves as the mounting base for various functional mechanisms and devices. Specifically, the frame 500 may include a tabletop 510, columns 520 supporting the tabletop 510, side panels 530, beams 540 connecting between the columns 520, and reinforcing plates 550 for enhanced support. The tabletop 510 may be divided into zones based on the boundaries between the material bag separation device and the bag positioning mechanism 400. The positions and number of the columns 520, side panels 530, beams 540, and reinforcing plates 550 may also be configured based on the zones of the tabletop 510. Specifically, in the embodiment shown in Figure 1, the table 510 includes a first area 511 for setting the material bag separation device and a second area 512 for setting the bag position mechanism 400. The four corners of the table 510 and the boundary between the first area 511 and the second area 512 are provided with columns 520, and cross beams 540 are provided between adjacent columns 520. The first area 511 is provided with a first opening for arranging the conveyor belt 300 and side baffles 530 are provided on both sides. The second area 512 is provided with a second opening for arranging components such as the screw 401, the left-handed nut seat 402, and the right-handed nut seat 403. The lower side of the second area 512 is provided with a guide rail mounting plate 560 for installing the positioning plate guide rail 408 and an auxiliary mounting plate 570 for installing components such as the motor 404. The lower side of the corner of the second area 512 is provided with a reinforcing plate 550.

[0053] The operation of the material bag separation mechanism, the material bag separation device and the bag feeding machine of the present application will be described below with reference to the accompanying drawings.

[0054] First, the material bag stack to be taken out (ie, the working bag stack) is transported to the end of the conveyor belt 300 by the conveyor belt 300 , so that both sides of the material bag stack are positioned by the first baffle P1 and the second baffle P2 respectively.

[0055] The bag removal operation can then begin. Specifically, the lifting device 230 drives the suction cup 211 and the ramming rod 212 downward, allowing the suction cup 211 to absorb the material bag P to be removed. During the descent, the ramming rod 212 contacts the slider 153 and drives the slider 153 downward to the bottom. The slider 153 pulls the separator mounting seat 120 and the separator 110 to their highest positions. Simultaneously, the elastic member 140 extends, exerting a downward force on the separator mounting seat 120. At this point, the stack of material bags is relatively high. When the separator 110 is at its highest position, at least the portion near the upper edge of the separator 110 acts on the material bag P to be removed. When the lifting device 230 drives the suction cup 211 and the ramming rod 212 upward, the separator mounting seat 120 moves downward under the action of the elastic member 140. The separator 110 moves in the opposite direction of the material bag absorbed by the suction cup 211, separating the material bag from the stack of material bags below.

[0056] The bag transfer device 220 then moves the lifting device 230 and the suction cup 210 from the bag removal position to the bag supply position, releasing the suction cup 211 and placing the material bag between the two positioning plates 410 of the bag positioning mechanism 400, completing the bag supply. Subsequently, the bag transfer device 220 moves the lifting device 230 and the suction cup 210 from the bag supply position to the bag removal position for another bag removal operation.

[0057] As the bag is taken out, the height of the material bag stack decreases, so that the separator 110 acts on the material bag P to be taken out through other parts below the lower edge when it is at the highest position, and the separation is completed by the reverse movement of the separator 110 and the material bag adsorbed by the suction cup 211.

[0058] When all bags in a stack of material bags have been removed, the conveyor belt 300 moves the stack of material bags downstream in the conveying direction (i.e., spare bag stack 1 in Figure 2) to the end of the conveyor belt 300, so that both sides of the stack of material bags are positioned by the first baffle P1 and the second baffle P2, respectively, and then the stack of material bags can be removed. A sensor can be provided to monitor whether there are material bags at the end of the conveyor belt 300. This sensor can be electrically connected to the drive control unit of the conveyor belt 300 to automatically control the conveyor belt 300 to convey a new stack of material bags when it detects that there are no material bags at the end of the conveyor belt 300.
