Abstract

The application discloses a material bag separating mechanism, a material bag separating device and a bag feeder. The material bag separating mechanism (100) comprises a separating piece (110), a separating piece mounting seat (120) and a separating piece fixing seat (130). The separating piece (110) is used for separating adjacent stacked material bags and is mounted on the separating piece mounting seat (120). The separating piece mounting seat (120) is mounted on the separating piece fixing seat (130) in a lifting manner. The separating piece can separate the adjacent stacked material bags to overcome the adhesion caused by static electricity. The separating piece mounting seat can lift or lower the separating piece relative to the stacked material bag pile, so that the height of the separating piece can be adjusted when the height of the material bag pile is lowered along with the taking of the material bags. Therefore, the separating piece can always be at a proper height for the current material bag to be taken, and the separating piece can sufficiently separate the material bag to be taken.

Description

Technical Field

[0001] This application relates to the field of material packaging, and more specifically, to a material bag separating mechanism, a material bag separating device, and a bag feeding machine. Background Technology

[0002] Currently, fully automatic packaging machines use bag feeders to automatically supply bags, thereby improving automation and packaging efficiency. The bag feeder is used to individually remove bags from a stack of stacked material bags. However, due to static electricity, the stacked bags are prone to sticking together, causing the bag feeder to pick up too many bags at once, thus affecting other processes after bag feeding.

[0003] Therefore, how to improve the problem of bag adhesion is the technical problem that this application needs to solve. Summary of the Invention

[0004] In view of this, this application proposes a material bag separation mechanism to improve the adhesion during bag removal, thereby increasing the success rate of bag removal, bag feeding and packaging.

[0005] This application provides a material bag separation mechanism, wherein the material bag separation mechanism includes a separating component, a separating component mounting base, and a separating component fixing base. The separating component is used to separate material bags from adjacent stacks and is installed on the separating component mounting base. The separating component mounting base is vertically and flexibly installed on the separating component fixing base.

[0006] This 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 this application.

[0007] This application also provides a bag feeding machine, wherein the bag feeding machine includes the material bag separating device of this application and a bag positioning mechanism disposed adjacent to the material bag separating device, and the bag picking mechanism is configured to move the material bag above the bag positioning mechanism.

[0008] According to the technical solution of this application, the separator can separate adjacent stacked material bags to overcome the adhesion caused by static electricity. The separator can be raised and lowered relative to the stacked material bags via the separator mounting base, so as to adjust the height as the height decreases as the material bags are taken, ensuring that the separator is always at the appropriate height to act on the material bag to be taken, and fully separating the material bag to be taken.

[0009] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0024] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] According to one aspect of this application, a material bag separation mechanism is provided, wherein the material bag separation mechanism 100 includes a separating member 110, a separating member mounting base 120 and a separating member fixing base 130, the separating member 110 is used to separate adjacent stacked material bags and install them on the separating member mounting base 120, and the separating member mounting base 120 is vertically and vertically mounted on the separating member fixing base 130.

[0026] Using the material bag separation mechanism of this 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 stacked material bags via the separator mounting base 120, so that the height can be adjusted as the height decreases as the material bag is taken, ensuring that the separator 110 is always at the appropriate height to act on the material bag P to be taken, so as to fully separate the material bag P to be taken.

[0027] The separator 110 may take a suitable form, for example, it may include a brush, which allows the brush bristles to be inserted between adjacent material bags P to overcome electrostatic stripping of adjacent material bags P.

[0028] 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 is provided with a sliding groove 131, and the other is slidably disposed in the sliding groove 131. For example, in Figure 7 In the embodiment shown, the slide groove 131 is provided on the separator fixing seat 130, and the separator mounting seat 120 may be provided with a slider part that cooperates with the slide groove 131.

[0029] To allow the separator mounting base 120 to rise and fall relative to the separator fixing base 130, the material bag separating mechanism 100 may include a drive unit for driving the separator mounting base 120 to move along the slide 131. Specifically, the slide 131 may be a linear groove arranged along the height direction, and the drive unit may be configured in an appropriate form to drive the separator mounting base 120 to move linearly.

[0030] The drive unit can be controlled in an appropriate manner to adjust the position of the separator mounting base 120 according to the needs of the bag-removing operation, adapting to the current height of the material bag stack and ensuring that the separator 110 can act on the uppermost material bag to be removed. Specifically, the movement range and movement mode of the separator mounting base 120 can be reasonably set so that at least a portion of the separator 110 (i.e., any part between the upper and lower edges of the separator 110) can act on the material bag to be removed. For example, the separator mounting base 120 can be initially located at the highest position, and when the height of the material bag stack decreases due to bag removal, the separator mounting base 120 can be lowered so that at least a portion of the separator 110 can act on the height of the material bag to be removed. Alternatively, the separator mounting base 120 can be initially located at the lowest position, and can be raised during bag removal so that at least a portion of the separator 110 can act on the height of the material bag to be removed.

[0031] According to another aspect of this application, a material bag separating device is provided, wherein the material bag separating device includes the material bag separating mechanism 100 and the bag taking mechanism 200 of this application.

[0032] To enable the separator mounting base 120 to rise and fall relative to the separator fixing base 130, the material bag separating mechanism 100 may include a drive unit for driving the separator mounting base 120 to rise and fall. Specifically, the drive unit may be configured in an appropriate form to drive the separator mounting base 120 to move linearly along the height direction.

[0033] The bag-retrieving mechanism 200 can be of an appropriate form to perform bag-retrieving operations one by one from top to bottom of the material bag stack. Specifically, the bag-retrieving mechanism 200 can be raised and lowered to perform the bag-retrieving operation. Understandably, as the bag-retrieving operation proceeds, the height of the material bag stack gradually decreases, and the height of the separating member 110 needs to be adjusted accordingly. Therefore, the raising and lowering of the bag-retrieving operation can be linked to the height adjustment of the separating member 110. Preferably, the bag-retrieving mechanism 200 includes a raiseable suction cup 210, which includes a suction cup 211 and a tamping rod 212. The raising and lowering of the tamping rod 212 is linked to the drive of the driving unit. Specifically, as bag retrieval proceeds and the height of the material bag stack decreases, the driving unit can be actuated by the tamping rod 212 to move the separating member mounting base 120, thereby matching the height of the material bag P to be retrieved. This allows the separating member 110 to act on the material bag P to be retrieved (i.e., so that the material bag P to be retrieved is located between the upper and lower edges of the separating member 110) for separation during bag retrieval.

[0034] Furthermore, preferably, when using the separator 120 to separate adjacent material bags P, the separator 120 can be made to move downward relative to the upper material bag P to achieve a better peeling effect. For this purpose, the drive unit may include an elastic member 140 acting on the separator mounting base 120 and a drive unit 150 connected to the separator mounting base 120 to overcome the elastic force of the elastic member and drive the separator mounting base 120 to move. The descent of the tamping rod 212 can actuate the drive unit 150 to drive the separator mounting base 120 upward, so that the separator 110 can act on the material bag to be removed. The elastic force of the elastic member 140 is set to cause the separator mounting base 120 to move downward when the tamping rod 212 rises. That is, when the tamping rod 212 moves downward, it actuates the drive of the bag-retrieving unit 150, causing the separating element mounting base 120 to drive the separating element 110 to move upward against the action of the elastic element 140 to the position of the corresponding material bag to be retrieved. When the suction cup 211 picks up the material bag P and moves upward, the tamping rod 212 moves upward accordingly, and the separating element mounting base 120 moves downward under the elastic force of the elastic element 140. This causes the separating element 110 and the suction cup 211 to pick up the material bag P upward in opposite directions, thereby improving the peeling effect and success rate.

[0035] The elastic element 140 can be configured in an appropriate form to provide the required elastic force. Specifically, for example... Figures 7 to 9 As shown, the elastic element 140 can be a tension spring. One end of the tension spring can be fixed to the bottom of the separator fixing seat 130, and the other end can be connected to the bottom of the separator mounting seat 120, so as to always provide a downward pulling force to the separator mounting seat 120.

[0036] The drive unit 150 can be suitably configured to generate upward movement of the separator mounting base 120 by actuating the descent of the tamping rod 212. Figure 7 and Figure 8 In the illustrated embodiment, the drive unit 150 may include a transmission belt 151, a guide wheel 152, and a slider 153 capable of rising and falling relative to the separator mounting base 130. The guide wheel 152 is rotatably mounted on the top of the separator mounting base 130. The transmission belt 151 is arranged around the guide wheel 152 and its two ends are respectively connected to the separator mounting base 120 and the slider 153. The tamping rod 212 can move to engage with the slider 153 and drive the slider 153 to move against the elastic force. Specifically, when the suction cup portion 120 descends, the tamping rod 212 descends and abuts against the slider 153 through its lower end, causing the slider 153 to move downward, which in turn drives the separator mounting base 120 to move upward via the transmission belt 151.

[0037] In this application, to facilitate control and extend the service life of the material bag separation mechanism 100 (e.g., to avoid frequent changes in the degree of extension and contraction of the elastic element 140), it can be configured to always actuate the slider 153 by the tamping rod 212 to slide the same distance, that is, to always raise the separator 110 to the same highest position. It is understood that, to ensure effective action on the material bag to be retrieved, the height between the upper and lower edges of the separator 110 should not be less than half the highest height of the material bag stack, so that the height of any material bag to be retrieved is between the lower edge of the separator 110 at its lowest position (i.e., not moved upwards by the slider 153) and the upper edge of the separator 110 at its highest position (i.e., the highest position moved upwards by the slider 153). For example, the upper edge of the separator 110 at its highest position can reach the highest height of the material bag stack. In this case, when the material bag stack is high, at least the portion near the upper edge of the separator 110 at its highest position can act on the material bag to be taken and can move downward relative to the material bag to be taken during bag removal so that the material bag substantially 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 during bag removal so that the material bag substantially passes through the entire separator 110.

[0038] In this situation, it is understandable that as the stack of material bags is removed, the height of the topmost bag gradually decreases, and the stroke of the tamping rod 212 will decrease. To avoid damage to the tamping rod 212, its stroke can be made variable. For example, the tamping rod 212 can be made telescopic. Preferably, as... Figure 11 As shown, the suction cup portion 210 includes a mounting frame 213 and a compression spring 214. The suction cup 211 is mounted on the mounting frame 213. The mounting frame 213 is provided with a slide rail arranged along the lifting direction of the suction cup portion 210. The tamping rod 212 slides with the slide rail. The compression spring 214 is compressed between the mounting frame 213 and the tamping rod 212 to provide a downward force to the tamping rod 212. Specifically, the slide rail can be a vertically arranged through hole on the mounting frame 213. The tamping rod 212 passes through the through hole. A boss can be provided at the lower part of the tamping rod 212. The compression spring 214 can be arranged around the tamping rod 212. The two ends of the compression spring 214 can respectively abut against the lower edge of the through hole of the mounting frame 213 and the boss. Thus, as the height of the material bag stack decreases, the distance that the tamping rod 212 extends downward from the through hole decreases.

[0039] In addition, by setting a compression spring 214, damage caused by excessive reaction force on the tamping rod 212 can be avoided. The compression spring 214 can be set to have a hardness slightly greater than that of the elastic element 140, so that when the height of the material bag stack is high, it can support the tamping rod 212 to extend a longer distance out of the through hole and actuate the slider 153.

[0040] To facilitate the removal of bags from multiple stacks of material bags, preferably, such as Figures 1 to 5 As shown, the material separation device may include a conveyor belt 300, and 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-taking mechanism 200 is disposed above the aforementioned end of the conveyor belt 300 and includes a tamping rod 212 capable of connecting the driving portions of the first material bag separation mechanism 100a and the second material bag separation mechanism 100b respectively. The material separation device includes a plurality of second material bag separation mechanisms 100b spaced apart on the conveyor belt 300. Thus, the material bags can be separated at their respective two edges by the first material bag separation mechanism 100a and the second material bag separation mechanism 100b.

[0041] Multiple stacks of material bags can be roughly positioned between two adjacent second material bag separation mechanisms 100b. When it is necessary to remove a bag from a stack of material bags, the stack can be conveyed to one end of the conveyor belt 300, so that one side of the stack is positioned by the first material bag separation mechanism 100a and the other side by the second material bag separation mechanism 100b, thus cooperating with the bag removal mechanism 200 to remove the bag. After one stack of material bags has been removed, the adjacent stack of material bags downstream in the conveying direction can be conveyed to the same end of the conveyor belt 300 for bag removal operations.

[0042] To accommodate material bags of different sizes, preferably, the position of the tamping rod 212 is adjustable along the conveying direction of the conveyor belt 300. For example, in Figure 11 In the embodiment shown, the mounting bracket 213 may include a main body 2131 and a support 2132. The suction cup 211 is mounted on the main body 2131, and the tamping rod 212 is mounted on the support 2132. One of the main body 2131 and the support 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 support 2132 and the tamping rod 212 can be aligned with the appropriate mounting holes and the assembly holes and installed with fasteners to achieve position adjustment of the support 2132 and the tamping rod 212 relative to the main body 2131.

[0043] Furthermore, preferably, multiple first material bag separation mechanisms 100a and multiple second material bag separation mechanisms 100b can be provided transversely to the conveying direction of the conveyor belt 300. That is, as shown in the example... Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, multiple sets of second material bag separation mechanisms 100b are arranged along the transmission direction. Each set of second material bag separation mechanisms 100b is arranged transversely to the transmission direction. When taking out a bag, the two sides of the material bag to be taken out are separated by multiple first material bag separation mechanisms 100a and multiple second material bag separation mechanisms 100b respectively.

[0044] Correspondingly, the suction cup section 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. Furthermore, to provide balanced and stable adsorption to the material bag to be removed, the suction cup section 210 may include a plurality of suction cups 211, which may be evenly arranged in rows and columns to adsorb different parts of the surface of the material bag. Specifically, the suction cups 211 may be disposed on the lower side of the main body 2131, and the main body 2131 may be provided with an air extraction pipe 214 communicating with the suction cups 211. A guide sleeve 215 may be disposed on the upper side of the main body 2131 around the air extraction pipe 214, and a suction cup compression spring 216 may be disposed between the inner hole of the guide sleeve 215 and the outer circle of the air extraction pipe 214.

[0045] To facilitate precise positioning of the material bag and improve the accuracy and success rate of bag retrieval, preferably, the material separation device includes a baffle for positioning the material bag corresponding to the material bag separation mechanism 100, and the separating member 110 extends beyond the surface of the baffle to contact the material bag. The baffle maintains a relatively fixed positional relationship with the corresponding material bag separation mechanism 100. Specifically, as shown... Figure 1 As shown, 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 the same as the width of the material bag (the positions of the first baffle P1 and the second baffle P2 can be adjusted to suit material bags of different sizes). The distance between the separation element mounting seats 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. The distance between the front ends (i.e., the ends acting on the material bag) of the separation elements 110 of the first material bag separation mechanism 100a and the second material bag separation mechanism 100b is less than the width of the material bag. For example, the separation element 110 is a brush, with the root of the brush connected to the separation element mounting seat 120 and the tip of the brush being the front end of the separation element 110. The tip of the brush can extend into the material bags.

[0046] To balance the positioning function of the baffle and the separation function of the material bag separation mechanism 100, and to avoid interference between the separating component 110 and the baffle, preferably, the baffle and the corresponding material bag separation mechanism 100 can be arranged alternately transversely to the conveying direction. Specifically, the conveyor belt 300 can have multiple conveyor belt sections 310 arranged side by side. These multiple conveyor belt sections 310 can be driven by the same set of drive units 320 (including a drive shaft 321 and a pulley 322 driven by the drive shaft 321). The second baffle P2 and the second material bag separation mechanism 100b can be alternately arranged on the multiple conveyor belt sections 310. Figure 1 , Figures 4 to 6 As shown, five conveyor belt sections 310 are arranged in sequence. The first, third, and fifth conveyor belt sections 310 are respectively equipped with second material bag separation mechanisms 100b, and the second and fourth conveyor belt sections 310 are equipped with second baffles P2. The first material bag separation mechanism 100a is arranged in the conveying direction corresponding to the second material bag separation mechanism 100b, and the first baffle P1 is arranged in the conveying direction corresponding to the second baffle P2.

[0047] According to another aspect of this application, a bag feeding machine is also provided, wherein the bag feeding machine includes the material bag separating device of this application and a bag positioning mechanism 400 disposed adjacent to the material bag separating device, and the bag picking mechanism 200 is configured to move the material bag above the bag positioning mechanism 400.

[0048] In use, after the bag-taking mechanism 200 takes a bag from the stack of material bags, it can move the material bag above the bag positioning mechanism 400 and place the material bag at the bag positioning mechanism 400, thereby completing the bag supply.

[0049] 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 picking mechanism 200 can be configured to move the suction cup part 210 along the conveying direction so as to place the material bag at the bag positioning mechanism 400. Specifically, the bag picking mechanism 200 may include a bag transferring device 220 and a lifting device 230 for lifting the suction cup part 210. The bag transferring device 220 includes a fixing plate 221 for fixing to the mounting base (e.g., the crossbeam 540 of the frame 500 below), a slide rail 222 mounted on the fixing plate 221, a slider 223 that slides with the slide rail 222, a mounting bracket 224 for connecting the slider 223 and 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-picking position located above one end of the conveyor belt 300 and a bag-feeding position located above the bag positioning mechanism 400, so that after picking up the bag at the bag-picking position, the material bag is moved to the bag-feeding position, and after feeding the bag, it returns to the bag-picking position to pick up the bag again. The lifting device 230 can take an appropriate form, such as a cylinder, and can be connected to the main body 2131 to drive the suction cup 211 and the tamping rod 212 to rise and fall through the lifting main body 2131.

[0050] To facilitate the positioning of material bags, such as Figure 12 As shown, the bag positioning mechanism 400 may include positioning plates 410 positioned relative to each other to position the material bags. The distance between the positioning plates 410 is adjustable to facilitate positioning material bags of different sizes. Specifically, the bag positioning mechanism 400 may include a screw 401, a left-hand nut seat 402, a right-hand nut seat 403, and a drive unit for driving the screw 401. The screw 401 has threads with opposite directions on both sides. The left-hand nut seat 402 and the right-hand nut seat 403 are respectively disposed on the threads on both sides of the screw 401. The two positioning plates 410 are respectively mounted on the left-hand nut seat 402 and the right-hand nut seat 403 so that they can move closer to or further away from each other when the drive unit drives the screw 401 to rotate. The drive unit may be of an appropriate form to drive the screw 401 to rotate in both directions. For example, the drive unit may include a motor 404, a drive wheel 405, a pulley 406, and a transmission belt 407. The motor 404 drives the drive wheel 405, the pulley 406 is fixed to the middle of the screw 401, and the pulley 405 and the drive wheel 405 are driven by the transmission belt 407. In addition, to guide the positioning plates 410 to move closer or further apart, the bag positioning mechanism 400 may also include a positioning plate guide rail 408 and two positioning plate sliders 409 that slide in cooperation with the positioning plate guide rail 408. A left-handed nut seat 402 and a right-handed nut seat 403 are respectively mounted on the two positioning plate sliders 409.

[0051] The bag feeding machine of this application may include a frame 500 as the mounting base for various functional mechanisms and devices. Specifically, the frame 500 may include a platform 510, columns 520 supporting the platform 510, side baffles 530, crossbeams 540 connecting the columns 520, and reinforcing plates 550 for enhanced support. The platform 510 can be divided into areas according to the boundary between the material bag separation device and the bag positioning mechanism 400, and the positions and quantities of the columns 520, side baffles 530, crossbeams 540, and reinforcing plates 550 can also be set according to the partitioning of the platform 510. Specifically, in Figure 1 In the embodiment shown, the platform 510 includes a first area 511 for setting up a material bag separating device and a second area 512 for setting up a bag positioning mechanism 400. Columns 520 are erected at the four corners of the platform 510 and at the boundary between the first area 511 and the second area 512. A crossbeam 540 is provided between adjacent columns 520. The first area 511 has a first opening for arranging the conveyor belt 300 and side baffles 530 on both sides. The second area 512 has a second opening for arranging components such as the screw 401, the left-hand nut seat 402, and the right-hand nut seat 403. A guide rail mounting plate 560 for mounting the positioning plate guide rail 408 and an auxiliary mounting plate 570 for mounting components such as the motor 404 are provided on the lower side of the second area 512. A reinforcing plate 550 is provided on the lower side of the corner of the second area 512.

[0052] The operation of the material bag separation mechanism, material bag separation device and bag feeding machine of this application is described below with reference to the accompanying drawings.

[0053] First, the stack of material bags to be picked up (i.e., the working bag stack) is transported to the end of the conveyor belt 300, so that the two sides of the material bag stack are positioned by the first baffle P1 and the second baffle P2 respectively.

[0054] Then the bag removal operation can begin. Specifically, the lifting device 230 lowers the suction cup 211 and the tamping rod 212, causing the suction cup 211 to adsorb the material bag P to be removed. During the descent, the tamping rod 212 contacts the slider 153 and causes the slider 153 to descend to the bottom. The slider 153 pulls the separator mounting base 120 and the separator 110 to rise to their highest positions. At the same time, the elastic element 140 extends, providing a downward force on the separator mounting base 120. At this time, the material bag stack is relatively high. When the separator 110 is at its highest position, at least the upper edge of the separator 110 acts on the material bag P to be removed. When the lifting device 230 raises the suction cup 211 and the tamping rod 212, the separator mounting base 120 moves downward under the action of the elastic element 140. The separator 110 moves in the opposite direction to the material bag adsorbed by the suction cup 211, separating the material bag from the material bag stack below.

[0055] Then, the bag transfer device 220 moves the lifting device 230 and the suction cup 210 together from the bag-picking 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 this bag supply. Subsequently, the bag transfer device 220 moves the lifting device 230 and the suction cup 210 together from the bag-supply position to the bag-picking position for another bag picking operation.

[0056] As the bag removal process proceeds, the height of the material bag stack decreases, causing the separator 110 to act on the material bag P to be removed through other parts below its lower edge when it is at its highest position. The separation is completed by the reverse movement of the separator 110 and the material bag adsorbed by the suction cup 211.

[0057] Once all bags in a stack of material bags have been removed, the conveyor belt 300 will move downstream to the next stack of material bags (i.e., ...). Figure 2 The spare bag stack is moved to the end of the conveyor belt 300, so that both sides of the bag stack are positioned by the first baffle P1 and the second baffle P2 respectively, and then the bags can be removed from the bag stack. A sensor can be installed to monitor whether there are 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 transport a new bag stack when no bags are detected at the end of the conveyor belt 300.
