[0081] Specifically, the loading component 100 comprises a bearing part 110, a rotating disc 120 and a knocking mechanism unloading cylinder 130, the rotating disc 120 is rotatably arranged on the bearing part 110, a plurality of unloading cylinders 130 are distributed along the circumference of the rotating disc 120, the bearing part 110 is provided with at least one unloading opening 140 matched with the unloading cylinder 130, the material enters the packaging bag through the unloading opening 140 and the unloading cylinder 130, a plurality of knocking mechanisms are arranged on the rotating disc, the plurality of knocking mechanisms are arranged in correspondence with the plurality of unloading cylinders and are used for knocking each unloading cylinder.

[0082] In the embodiment, the knocking mechanism can adopt the knocking mode of a vibration motor or an air cylinder, and the main function is to avoid the accumulation of powder in the unloading cylinder 130.

[0083] It should be noted that the bearing part 110 is a cylindrical structure with a sealed top, and the bearing part 110 is coaxially arranged with the rotating disc 120.

[0084] It should be noted that the number of the blanking cylinders 130 can be adjusted according to the actual process and the setting of the work stations, and in the embodiment, seven blanking cylinders 130 are preferably adopted to form a seven-station design.

[0085] Through the above design, the packaging bags can be conveyed one by one to the filling component 100 by the packaging bag conveying component 200, and the materials can be conveyed to the filling component 100 by the material conveying component 300, and the packaging bags are filled by the filling component 100; through the integration of the packaging bag conveying component 200, the material conveying component 300 and the filling component 100, automatic material conveying, automatic packaging bag conveying and automatic filling are realized, so that automatic production is realized, and the work efficiency is greatly improved, and the labor loss is reduced.

[0086] Overall, the multi-station packing machine 2000 provided by the embodiment of the application has high automation, greatly improves the work efficiency, reduces the excessive loss of labor, and is beneficial to realize automatic production.

[0087] Further, in the embodiment, in order to enable the packaging bag to be clamped on the blanking cylinder 130 after being sleeved on the blanking cylinder 130, a clamping assembly 150 is specially added, the clamping assembly 150 comprises a first clamping arm 151, a second clamping arm 152, a first bag straightening hook 153 and a second bag straightening hook 154, the first clamping arm 151 and the second clamping arm 152 are movably arranged on the two sides of the blanking cylinder 130 respectively, and the first clamping arm 151 and the second clamping arm 152 can move relative to each other along a first direction to clamp the packaging bag on the blanking cylinder 130.

[0088] The first bag straightening hook 153 and the second bag straightening hook 154 are movably arranged on the two sides of the blanking cylinder 130 respectively, and the first bag straightening hook 153 and the second bag straightening hook 154 can move relative to each other along a second direction to straighten the bag opening of the filled packaging bag; the first direction and the second direction are located in the same plane and perpendicular to each other.

[0089] It should be noted that the first direction and the second direction are only virtual directions, and are only used to illustrate the movement directions of the first clamping arm 151 and the second clamping arm 152 and the movement directions of the first bag straightening hook 153 and the second bag straightening hook 154.

[0090] In the embodiment, the first clamping arm 151 and the second clamping arm 152 are rotatably arranged on the turntable 120, and the first clamping arm 151 and the second clamping arm 152 are located on the two sides of the blanking cylinder 130 respectively, and the first clamping arm 151 and the second clamping arm 152 are respectively connected with a first air cylinder for driving the first clamping arm 151 and the second clamping arm 152 to rotate to move closer to or away from the blanking cylinder 130, so that the two sides of the opening of the packaging bag are clamped on the two sides of the blanking cylinder 130, and the clamping of the packaging bag is realized.

[0091] In addition, the first bag hook 153 and the second bag hook 154 are rotatably arranged on the rotating disc 120, and the first clamping arm 151 and the second clamping arm 152 are respectively arranged on both sides of the dispensing cylinder 130 away from the first clamping arm 151 and the second clamping arm 152, and the first bag hook 153 and the second bag hook 154 are respectively connected with a second cylinder for driving the first bag hook 153 and the second bag hook 154 to rotate to approach or move away from each other and the dispensing cylinder 130.

[0092] In actual use, the first bag hook 153 and the second bag hook 154 are initially arranged close to the dispensing cylinder 130 (closed state), and the first clamping arm 151 and the second clamping arm 152 are arranged away from each other (open state), when the packaging bag is sleeved on the dispensing cylinder 130 (the first bag hook 153 and the second bag hook 154 are located in the packaging bag), the first cylinder drives the first clamping arm 151 and the second clamping arm 152 to approach each other to clamp the packaging bag on the dispensing cylinder 130; after the loading is completed, the first cylinder drives the first clamping arm 151 and the second clamping arm 152 to move away from each other, and at the same time, the second cylinder drives the first bag hook 153 and the second bag hook 154 to move away from each other, at this time, the packaging bag is lowered under the action of gravity, and the first bag hook and the second bag hook 154 straighten the bag opening of the packaging bag.

[0093] Through the design of the first bag hook 153 and the second bag hook 154, the bag opening of the packaging bag can be straightened after the loading is completed (since the bag opening of the packaging bag needs to be sewn later, and in the traditional production, the bag opening of the packaging bag needs to be manually straightened before entering the sewing machine 3000), so that the packaging bag can directly enter the sewing machine 3000, greatly improving the work efficiency.

[0094] In the embodiment, at least one material conveying component 300 is matched with the dispensing opening 140;

[0095] At present, the powder is transported by the auger mechanism 310, but the precision of the auger conveying mechanism is difficult to control, and the accurate conveying of the precise weight material cannot be realized. In order to solve this problem, part of the equipment adopts a double auger structure, that is, two auger mechanisms 310 with different diameters are arranged, when a large range of feeding is required, the auger with a larger diameter is used to convey the material, when the material approaches the threshold, the auger with a larger diameter is closed, and the auger with a smaller diameter is used for micro-feeding, so as to control the feeding amount, and the feeding amount is relatively more accurately controlled, but this way still has great disadvantages, first, although the auger with a smaller diameter is used for micro-feeding, based on the structural characteristics of the auger conveying, although the up and down floating amount of the feeding amount can be greatly reduced, but the problem of accurate feeding cannot be solved; second, when two augers are used, a tee joint is needed to make the two sets of augers communicate with the storage bin, which results in a large overall difference from the storage bin to the auger, and the pressure borne by the auger is large, which is easy to cause the auger to be damaged; third, the tee joint causes the material to pass through the tee joint with more corners, when the powder material is conveyed, the corners of the tee joint are easy to accumulate and cause blockage.

[0096] Based on the above problems, in the embodiment, the material conveying component 300 comprises: an auger mechanism 310, a material cutoff mechanism 320 and a weighing mechanism 330, the material cutoff mechanism 320 is arranged at the discharge port of the auger mechanism 310, the weighing mechanism 330 is arranged at the discharge port of the material cutoff mechanism 320, the discharge port of the weighing mechanism 330 is communicated with the lower outlet 140, and a cutoff valve is arranged at the discharge port of the weighing mechanism 330.

[0097] The material cutoff mechanism 320 is arranged at the discharge port of the auger mechanism 310, and is used to cut off the material at the discharge port of the auger mechanism 310; the material cutoff mechanism 320 comprises a discharge cylinder 321 and a cutoff door 322, the discharge cylinder 321 is connected with the auger mechanism 310, and the inner cavity of the discharge cylinder 321 is communicated with the discharge port; the discharge cylinder 321 has a discharge port on the side close to the ground, and the cutoff door 322 is rotatably arranged in the inner cavity of the discharge cylinder 321 and is located below the discharge port; so that the material is cut off in the inner cavity of the discharge cylinder 321.

[0098] It should be noted that the diameter of the discharge cylinder 321 is greater than the diameter of the auger conveying channel, so that the discharge cylinder 321 has a larger inner cavity to facilitate the flow of the material.

[0099] In actual use, the weighing mechanism 330 is arranged below the discharge port of the discharge cylinder 321, which can weigh the material discharged from the discharge port in real time, so as to accurately control the weight.

[0100] It should be noted that the cut-off door 322 is connected with a driving shaft 324, both ends of the driving shaft 324 are rotatably penetrated through the side wall of the discharge cylinder 321, and one end of the driving shaft 324 is provided with a rotating arm 325, and the side wall of the discharge cylinder 321 is provided with a driving cylinder 326, and the output end of the driving cylinder 326 is rotatably connected with the end of the rotating arm 325 away from the driving shaft 324.

[0101] When the material is conveyed, the material is first continuously conveyed by the auger mechanism 310, and then the material discharged from the discharge port enters the inner cavity of the discharge cylinder 321, and then is discharged through the discharge port, and the weighing mechanism 330 below weighs in real time, and when the weight reaches the threshold value, the control cut-off door 322 is closed, the cut-off door 322 closes the inner cavity of the discharge cylinder 321, so that the excess material discharged from the auger is cut off in the discharge cylinder 321, and the accuracy of the weight of the material entering the weighing mechanism 330.

[0102] It should be noted that since the material enters the weighing mechanism 330 from the discharge cylinder 321 by gravity, considering the distance between the cut-off door 322 and the weighing mechanism 330, there will be a certain error of the material, so in the actual production process, the distance between the cut-off door 322 and the weighing mechanism 330 should be as small as possible, so as to further reduce the error.

[0103] Through the above design, the cut-off door 322 can effectively cut off the material after being discharged from the auger mechanism 310 and before entering the weighing mechanism 330, so as to effectively control the excess material into the weighing mechanism 330, and further improve the accuracy of material conveying. When conveying the material next time, the material cut off this time can enter the weighing mechanism 330 first, and will not cause waste of the material.

[0104] Overall, the material conveying mechanism provided by the embodiment of the application can effectively and accurately control the amount of material conveyed by the auger mechanism 310, so as to realize the precision control of material discharge, and further improve the accuracy of material conveying.

[0105] In some embodiments, the cross section of the cut-off door 322 matches the cross section of the discharge cylinder 321, and the center line of the rotating shaft 341 of the cut-off door 322 passes through the center axis of the discharge cylinder 321.

[0106] It should be noted that in order to reduce the material accumulation caused by the corners of the equipment, in the embodiment, the discharge cylinder 321 adopts a cylindrical shape, and the diameter of the cut-off door 322 is the same as the inner diameter of the discharge cylinder 321.

[0107] Another need to be explained is, due to the driving mode of the cutoff door 322 adopts cylinder drive, considering that the cylinder only has the starting point and the end point of the stroke, therefore, in the actual implementation process, when the cylinder is in the stretched state, the cutoff door 322 rotates to its plane perpendicular to the ground, when the cylinder is in the contracted state, the cutoff door 322 rotates to its plane sealing the inner cavity of the discharge cylinder 321.

[0108] In other embodiments, the inner wall of the discharge cylinder 321 is provided with a support plate 323, the support plate 323 is located below the discharge port, the side edge of the support plate 323 away from the side of the auger mechanism 310 is rotatably connected to the cutoff door 322 through the driving shaft 324, and the remaining side edges are connected to the inner wall of the discharge cylinder 321; the two side edges of the cutoff door 322 along the central axis direction of the driving shaft 324 are attached to the inner wall of the discharge cylinder 321.

[0109] Specifically, the cutoff door 322 has a first side edge 3221, a second side edge 3222, a third side edge 3223 and a fourth side edge 3224, the first side edge 3221 is connected to the rotating shaft, the second side edge 3222 and the third side edge 3223 are respectively attached to the inner wall of the discharge cylinder 321, and the fourth side edge 3224 has a gap with the inner wall of the discharge cylinder 321; and the fourth side edge 3224 is connected with an extension plate 327; along the central axis of the discharge cylinder 321 and towards the side away from the discharge port, the extension plate 327 is inclinedly arranged.

[0110] It should be noted that the gap between the fourth side edge 3224 and the inner wall of the discharge cylinder 321 is adjusted according to the actual work; since the cutoff door 322 is closed, the auger mechanism 310 has stopped working, therefore, the remaining falling material will not fall from the gap between the fourth side edge 3224 and the inner wall of the discharge cylinder 321.

[0111] Another need to be explained is that the length of the extension plate 327 is the same as the length of the cutoff door 322, and the design of the extension plate 327 can effectively prevent the material intercepted by the cutoff door 322 from falling off the cutoff door 322.

[0112] Through the above design, the rotation radius of the cutoff door 322 can be effectively reduced, so that the cutoff door 322 rotates more flexibly, and the smaller rotation radius can more accurately control the falling amount of the material, avoiding that too much material still falls from the discharge port into the weighing mechanism 330 in the process of rotating and closing.

[0113] In this embodiment, in order to further avoid the pressure of the material in the large material storage bin at the auger inlet, which easily leads to the damage of the auger, and to avoid material caking, a material loosening mechanism 340 is specially added at the inlet of the auger mechanism 310, which is used to scatter the material entering the inlet.

[0114] Specifically, the loosening mechanism 340 comprises a rotating shaft 341, a first blade group and a second blade group. The rotating shaft 341 is rotatably arranged at the feeding port, and the central axis thereof is parallel to the central axis of the auger mechanism 310. A plurality of first blade groups are arranged along the central axis of the rotating shaft 341. A plurality of second blade groups are arranged along the central axis of the rotating shaft 341. The plurality of first blade groups and the plurality of second blade groups are sequentially arranged along the central axis of the rotating shaft 341.

[0115] In addition, the first blade group comprises a plurality of first loosening blades 342. The plurality of first loosening blades 342 are arranged along the axial direction of the rotating shaft 341.

[0116] The second blade group comprises a plurality of second loosening blades 343. The plurality of second loosening blades 343 are arranged along the axial direction of the rotating shaft 341.

[0117] It should be noted that the plurality of first blade groups are arranged at intervals, so that there is a gap between adjacent first blade groups, and the plurality of second blade groups are arranged in the gaps between adjacent first blade groups, thereby further improving the loosening efficiency.

[0118] It should be noted that the corresponding planes of the first loosening blades 342 and the corresponding planes of the second loosening blades 343 have a certain angle, that is, the first blade group and the second blade group are staggered, thereby further improving the loosening efficiency.

[0119] In addition, the height of the second loosening blade 343 is less than the height of the first loosening blade 342. The falling material can be first loosened by the first blade group, and when the loosened material continues to fall, the height of the second loosening blade 343 is less than the height of the first loosening blade 342, so that the material contacts the second loosening blade 343 and is loosened again, thereby improving the loosening efficiency.

[0120] In addition, in the present embodiment, the rotating shaft 341 is connected to the rotating shaft of the auger mechanism 310 through a belt and a belt pulley, so that the loosening mechanism 340 and the auger mechanism 310 are driven by the same driving source to rotate simultaneously, thereby greatly saving energy and enabling synchronous start and stop.

[0121] In the present embodiment, the control part is realized by a commonly used sensor. First, the weighing mechanism 330 is a weighing sensor, which monitors the weight data in real time and sends the data to the central control system. The central control system determines whether the data reaches the threshold value. When the threshold value is reached, a control signal is sent to the driving cylinder 326, and the driving cylinder 326 starts to work. This control board is a conventional prior art, which will not be described here.

[0122] In actual use, first, the auger mechanism 310 rotates, conveying the material while driving the loosening component to rotate, and the first blade group and the second blade group rotate to scatter the material entering the auger mechanism 310. At this time, part of the material is discharged from the discharge port into the discharge cylinder 321. Since the cutoff door 322 is in an open state, the material falls into the weighing mechanism 330 by gravity after passing through the inner cavity of the discharge cylinder 321. The weighing sensor detects the weight data in real time. When the weight of the material in the weighing mechanism 330 reaches a threshold value, the central control system controls the driving cylinder 326 to move, thereby driving the driving shaft 324 to rotate, driving the cutoff door 322 to rotate to be parallel to the ground, and cutting off the material in the discharge cylinder 321.

[0123] In the present embodiment, the material conveying component 300 preferably adopts at least two sets, thereby further improving work efficiency.

[0124] In the present embodiment, the packaging bag conveying component 200 includes a bag feeding mechanism 210 and a bag opening mechanism 220. The bag feeding mechanism 210 is used to convey the packaging bags one by one. The bag opening mechanism 220 is used to open and convey each packaging bag to be sleeved on the discharging cylinder 130. The clamping assembly 150 clamps the packaging bag on the discharging cylinder 130.

[0125] The bag feeding mechanism 210 includes a bag feeding conveying table 211 and an opening assembly 212. The opening assembly 212 is arranged at the discharge end of the bag feeding conveying table 211, so as to open the bag opening of the packaging bag.

[0126] The bag opening mechanism 220 includes a supporting part 221, a first opening assembly 222, and a second opening assembly 223. The supporting part 221 is rotatably arranged at the discharge end of the bag feeding mechanism 210. The first opening assembly 222 is arranged on the supporting part 221 and is used to open the bag opening of the packaging bag in a third direction. The second opening assembly 223 is arranged on the supporting part 221 and is used to open the bag opening of the packaging bag in a fourth direction. The third direction and the fourth direction are in the same plane, and the third direction and the fourth direction have an included angle A.

[0127] Specifically, the opening assembly 212 includes a driving member, a first opening suction disc 2121, and a second opening suction disc 2122 connected with the driving member. The first opening suction disc 2121 and the second opening suction disc 2122 form a gap for accommodating the bag opening of the material bag. When the bag feeding conveying table 211 conveys the material bag to the discharge end, the driving member can drive the first opening suction disc 2121 and / or the second opening suction disc 2122 to separate after moving close to each other, so as to open the bag opening of the material bag.

[0128] It should be noted that the third direction and the fourth direction are virtual directions, which are only used to express two different directions for opening the bag opening of the packaging bag.

[0129] In order to further expand the opening area of the packaging bag after being opened, the included angle A is 30°≤A≤90°, preferably 90°, so as to ensure that the packaging bag is opened from the vertical direction.

[0130] The first opening assembly 222 comprises a first bag stretching part 2224, a second bag stretching part 2225, a first support arm 2221, a second support arm 2222, and a bag stretching cylinder group 2223. The first bag stretching part 2224 and the second bag stretching part 2225 can be relatively close or far apart in the first direction.

[0131] One end of the first support arm 2221 is connected with the first bag stretching part 2224, and the other end is rotatably connected with the support part 221. One end of the second support arm 2222 is connected with the second bag stretching part 2225, and the other end is rotatably connected with the support part 221. The bag stretching cylinder group 2223 is movably connected with the first support arm 2221 and / or the second support arm 2222.

[0132] It should be noted that the rotatable connection of the first support arm 2221 and the second support arm 2222 with the support part 221 can adopt the form of a rotating shaft 341 or other common rotating connection forms, which will not be described here. In addition, the center lines of the rotating shafts 341 of the first support arm 2221 and the second support arm 2222 are parallel, and perpendicular to the center line of the rotating shaft 341 of the support part 221.

[0133] Specifically, in order to ensure that the angles of rotation of the first support arm 2221 and the second support arm 2222 are the same when this method is used, a limiting assembly 230 is specially added. The limiting assembly 230 comprises a limiting connecting rod 231 and a connecting arm 232. One end of the connecting arm 232 is connected with the second support arm 2222, and the other end extends away from the second bag stretching part 2225 along the axial direction of the second support arm 2222. One end of the limiting connecting rod 231 is rotatably connected with the first support arm 2221, and the other end is rotatably connected with the end of the connecting arm 232 away from the second support arm 2222.

[0134] It should be noted that the center axis of the connecting arm 232 is parallel to the center axis of the second support arm 2222, and the connecting arm 232 spans the center line of the rotating shaft 341 of the second support arm 2222 (i.e. the center line of the rotating shaft 341 of the second support arm 2222 passes through the center of the connecting arm 232).

[0135] Another point to note is that the distance from one end of the limiting connecting rod 231 to the center line of the rotating shaft 341 of the first support arm 2221 is the same as the distance from the other end of the limiting connecting rod 231 to the center line of the rotating shaft 341 of the second rotating arm 325.

[0136] Through the design, the first supporting arm 2221 and the second supporting arm 2222 can be driven to rotate around the rotation shaft 341 as the axis by the stretching or contraction of the bag stretching cylinder group 2223, so as to drive the first bag stretching part 2224 and the second bag stretching part 2225 to approach or move away from each other, thereby achieving the third direction opening of the packaging bag. In addition, under the action of the limiting assembly 230, the angles of rotation of the first supporting arm 2221 and the second supporting arm 2222 can be ensured to be the same.

[0137] The above two modes are only different in the implementation process, but the ultimate goal is to realize the relative motion (approach or move away from each other) of the first bag stretching part 2224 and the second bag stretching part 2225. In addition, there are other structures in the prior art that can realize this function, which will not be described here.

[0138] In the embodiment, the first supporting arm 2221 is provided with a first extension part 2226 at the end away from the supporting part 221, the central axis of the first extension part 2226 is perpendicular to the central axis of the first supporting arm 2221, and the first bag stretching part 2224 is arranged at the end of the first extension part 2226 away from the first supporting arm 2221.

[0139] The second supporting arm 2222 is provided with a second extension part 2227 at the end away from the supporting part 221, the central axis of the second extension part 2227 is perpendicular to the central axis of the second supporting arm 2222, and the second bag stretching part 2225 is arranged at the end of the second extension part 2227 away from the second supporting arm 2222.

[0140] The first bag stretching part 2224 is arranged obliquely along the direction close to the bag opening of the packaging bag and away from the second bag stretching part 2225, and the included angle between the first bag stretching part 2224 and the first direction is an acute angle.

[0141] The first bag stretching part 2224 is arranged obliquely along the direction close to the bag opening of the packaging bag and away from the first bag stretching part 2224, and the included angle between the second bag stretching part 2225 and the first direction is an acute angle.

[0142] In the embodiment, the second opening assembly 223 includes a first bag opening assembly and a second bag opening assembly, the first bag opening assembly is arranged on the first bag stretching part 2224, and the second bag opening assembly is arranged on the second bag stretching part 2225.

[0143] Specifically, the first bag opening assembly includes a first bag opening part 2231 and a second bag opening part 2232; along the first direction, the first bag opening part 2231 and the second bag opening part 2232 are respectively arranged on the two sides of the first bag stretching part 2224 in a rotatable manner.

[0144] The second bag assembly comprises a third bag portion 2233 and a fourth bag portion 2234; along the first direction, the third bag portion 2233 and the fourth bag portion 2234 are respectively rotatably arranged on both sides of the second bag portion 2225.

[0145] It should be noted that the rotatable driving mode of the first bag portion 2231 and the second bag portion 2232 can adopt the mode of a finger air cylinder; similarly, the rotatable driving mode of the third bag portion 2233 and the fourth bag portion 2234 can also adopt the mode of a finger air cylinder.

[0146] Through such a design, the first bag assembly can be arranged on the first bag portion 2224, and the second bag assembly can be arranged on the second bag portion 2225, so that a channel for discharging is formed between the first bag portion 2224 and the second bag portion 2225, and no component obstructs the discharging channel, thereby reducing the influence on the material entering the packaging bag.

[0147] Specifically, in the embodiment, the first bag portion 2231 and the second bag portion 2232 extend in the direction close to the bag opening of the packaging bag; the third bag portion 2233 and the fourth bag portion 2234 extend in the direction close to the bag opening of the packaging bag.

[0148] In addition, in the embodiment, considering that when the packaging bag is opened along the second direction, the width of the packaging bag along the first direction will be reduced by a certain distance, therefore, in the embodiment, the bag stretching air cylinder group 2223 comprises a first air cylinder and a second air cylinder connected to each other, the center axes of the first air cylinder and the second air cylinder coincide, and the strokes of the first air cylinder and the second air cylinder are different, when the second opening assembly 223 starts to work, the first air cylinder or the second air cylinder contracts, so as to adjust the distance of the packaging bag along the first direction. (That is, the distance of the packaging bag shortened along the first direction after being opened along the second direction is equivalent to the stroke of the first air cylinder or the second air cylinder).

[0149] In actual work process, the opening assembly 212 first opens the bag opening of the packaging bag, at this time the support part 221 rotates until the first opening assembly 222 and the second opening assembly 223 are located in the inner cavity of the packaging bag, then the bag stretching cylinder group 2223 drives the first support arm 2221 and the second support arm 2222 to move away from each other, so that the first bag stretching part 2224 and the second bag stretching part 2225 stretch the bag opening of the packaging bag in the third direction, at this time, the support part 221 reversely rotates to drive the first support arm 2221 and the second support arm 2222 to rotate synchronously, thereby driving the packaging bag to move synchronously, in the moving process, the second opening assembly 223 works, the first bag opening part 2231 and the second bag opening part 2232 move away from each other, the third bag opening part 2233 and the fourth bag opening part 2234 respectively move away from each other in the fourth direction, so as to stretch the packaging bag in the fourth direction, until the support part 221 rotates to the packaging bag being sleeved on the discharging cylinder 130, at this time, the clamping assembly 150 works, the first clamping arm 151 and the second clamping arm 152 clamp the packaging bag on the discharging cylinder 130, then the first opening assembly 222 and the second opening assembly 223 reset, the support arm rotates by a certain angle until the first opening assembly 222 and the second opening assembly 223 are separated from the inner cavity of the packaging bag, then the bag stretching cylinder group 2223 is stretched by a certain angle to make room, after the room is made, the support arm is positively rotated to drive the first support arm 2221 and the second support arm 2222 to enter the next packaging bag to be filled (the packaging bag stretched by the opening assembly 212), and the operation is repeated to realize the continuous conveying of the packaging bag.

[0150] In the embodiment, the control system adopts conventional PLC control, which is a conventional technology and will not be described here.

[0151] In the embodiment, the sewing machine 3000 adopts a conventional sewing machine 3000 in the prior art, which has a conveying part and a sewing part, the first clamping arm 151 and the second clamping arm 152 of the packaging bag after being filled by the packing machine 2000 move away from each other in a reverse direction, so that the packaging bag falls under gravity, at the same time, the second opening assembly 223 works, the first bag opening part 2231 and the second bag opening part 2232 move away from each other, the third bag opening part 2233 and the fourth bag opening part 2234 respectively move away from each other in the fourth direction, so as to stretch the packaging bag in the fourth direction, the packaging bag falling under gravity falls on the conveying part for conveying, and then is sewn by the sewing part.

[0152] In this embodiment, the bag taking mechanism 500 includes a bag taking assembly 502 and a bag dragging assembly 503. The bag taking assembly 502 includes a first driving part 5021 and a first executing part 5022 connected with each other in transmission, and the first executing part 5022 is provided with a first adsorption unit 5023 for adsorbing the packaging bag. The first driving part 5021 inputs power to drive the first executing part 5022 to move, so that the first adsorption unit 5023 can change the pose to facilitate the adsorption work of the packaging bag.

[0153] The driving part can be an electric, pneumatic or hydraulic element as power, such as a cylinder, an oil cylinder, a motor and other servo elements capable of realizing automatic operation. The executing part is mainly an element capable of linear, steering and / or rotating, such as a linear driving mechanism, a multi-link turning mechanism or a gear transmission mechanism, etc. Any existing combined mechanism capable of realizing the specified pose of the first adsorption unit can be used, and no further limitation is made here.

[0154] The bag dragging assembly 503 includes a second driving part 5031 and a second executing part 5032 connected with each other in transmission, and the second executing part 5032 is provided with a second adsorption unit 5033 for adsorbing the packaging bag. Similarly, the driving part and the executing part are described above, and the power is inputted to the second driving part 5031 to drive the second executing part 5032 to move, so that the pose of the second adsorption unit 5033 is changed to facilitate the adsorption work of the packaging bag. The adsorption unit described above can be a flexible adsorption unit such as magnetic adsorption, vacuum adsorption, sticky adsorption or clamping adsorption, which is used to take turns to adsorb the stacked packaging bags, so that the uppermost packaging bag can be smoothly separated or not be adhered, and the purpose of transferring the single packaging bag to the transfer station is achieved.

[0155] The first driving part 5021 and the first executing part 5022 are connected in extension and retraction to move back and forth, so that the first adsorption unit 5023 can perform extension and retraction reciprocating shaking on the packaging bag when adsorbing the packaging bag, thereby facilitating the second adsorption unit 5033 to adsorb and transfer the single packaging bag. That is, the first driving part 5021 and the first executing part 5022 are connected in extension and retraction, and the extension and retraction connection can form reciprocating movement between them, so that the first adsorption unit 5023 can drive the packaging bag to reciprocating shake through repeated extension and retraction, and the packaging bag can be smoothly shaken off to the lower adhered packaging bag, and the purpose of transferring the single packaging bag is achieved. The extension and retraction connection for reciprocating movement can be realized by a linear extension and retraction mechanism, such as a screw worm assembly, a gear and rack assembly, etc. It can also be realized by a direct extension and retraction mechanism, such as a telescopic cylinder, an electric telescopic rod, etc. It can also be realized by a multi-link assembly, such as a crank slider mechanism, which aims to form an extension and retraction connection between the first driving part 5021 and the first executing part 5022, and no further limitation is made here.

[0156] In addition, the direction of the telescopic reciprocating shaking is consistent with the stacking direction of the packaging bags during work, so that the adhesion of the packaging bags can be shaken off fully, that is, reciprocating shaking is performed according to the stacking direction of the packaging bags, and the shaking-off effect is better. Through the above technical scheme, when the first adsorption unit 5023 preliminarily grabs, the single packaging bag that is left after reciprocating shaking is adsorbed, and the second adsorption unit 5033 is controlled to adsorb and transfer, which not only does not increase the floor space of the equipment, but also can maintain high-efficiency single packaging bag transfer operation. Compared with the way of directly grabbing the packaging bag by the traditional grabbing mechanism, especially for the uncoated packaging bag (the adhesion between them is stronger), the phenomenon of adhesion of the packaging bag can be avoided during transfer.

[0157] In order to further ensure the anti-adhesion effect, in some embodiments, the bag taking mechanism 500 further comprises a bag suction assembly 501, the bag suction assembly 501 comprising a third driving part 5011 and a third executing part 5012 connected with each other in transmission, and a third adsorption unit 5013 for adsorbing packaging bags is installed on the third executing part 5012, so that the third adsorption unit 5013 adsorbs the lower layer of the packaging bags when the first adsorption unit 5023 adsorbs the packaging bags. Through this technical scheme, the third adsorption unit 5013 of the bag suction assembly 501 can physically separate when the packaging bags are adhered, that is, the first adsorption unit 5023 adsorbs one or more layers of packaging bags (usually one layer) when it adsorbs the packaging bags. At this time, the third driving part 5011 drives the third executing part 5012 to act, so that the third adsorption unit 5013 contacts and adsorbs the lower layer of the packaging bags, and then physically separates the lower layer of the packaging bags from the uppermost layer of the packaging bags by the whole displacement, so as to achieve the purpose of fully preventing adhesion.

[0158] The driving part, the executing part and the adsorption unit can be configured according to the above related content. However, considering that the action of the bag suction assembly 501 is highly matched with the action of the bag taking assembly 502 and does not interfere with the movement, in this embodiment, the third driving part 5011 comprises a first moving assembly 50111 and a second moving assembly 50112, both moving assemblies have a fixed end as a mounting end and an action end as an output end, for example, a conventional linear motion mechanism or a motion mechanism with linear output.

[0159] The second moving assembly 50112 is installed at the output end of the first moving assembly 50111, and the third execution part 5012 is installed at the output end of the second moving assembly 50112, so that the third adsorption unit 5013 can form an opposite adsorption direction with the first adsorption unit 5023. That is, when the third adsorption unit 5013 and the first adsorption unit 5023 adsorb the packaging bag, they respectively form opposite forces, so as to adapt to the position requirement of the lower packaging bag and the uppermost packaging bag. And by adopting the two-stage displacement mode, the above-mentioned motion interference can be avoided, that is, the first moving assembly 50111 drives the second moving assembly 50112 to move, and the second moving assembly 50112 drives the third adsorption unit 5013 to move, which can better avoid the moving route of the first adsorption unit 5023 when adsorbing the packaging bag from the stacking pile.

[0160] The moving direction of the first moving assembly 50111 and the second moving assembly 50112 forms an included angle, which can adapt to the above-mentioned change direction movement. In the embodiment, for example, the first moving assembly 50111 moves horizontally, and the second moving assembly 50112 moves vertically. When the packaging bag is detected to be adhered, the first moving assembly 50111 and the second moving assembly 50112 can be controlled to move in sequence. The detection method can be thickness detection, weight detection, infrared distance detection, etc., but considering the simplicity and effectiveness of the detection method, the weight detection method is adopted in the embodiment, that is, the novel packaging bag taking machine 1000500 further comprises a weighing sensor 5024 in communication connection with the third driving part 5011. The weighing sensor 5024 is used to sense the weight of the packaging bag adsorbed by the first adsorption unit 5023, for example, the weighing sensor 5024 is arranged between the first driving part 5021 and the first execution part 5022 or between the first driving part 5021 and the mounting platform. The weight of the whole or part of the taking assembly 502 can be detected, and the weight of the packaging bag grasped can be judged according to the weight change before and after grasping, and then the number of the packaging bag grasped can be judged.

[0161] On the basis of the above scheme, considering the process of separating the two-layer packaging bag by the third adsorption unit 5013 and the first adsorption unit 5023, on the one hand, the separation efficiency can be improved, and on the other hand, the lower packaging bag separated from the third adsorption unit 5013 can be buffered. The air blowing assembly 504 is specially added, the air nozzle 5041 of the air blowing assembly 504 is arranged between the bag taking assembly 502 and the packaging bag stacking station, and is used to form air flow on the lower packaging bag when the third adsorption unit 5013 adsorbs the adhered lower packaging bag. In different embodiments, if the air nozzle 5041 of the air blowing assembly 504 is arranged between the bag taking assembly 502 and the bag taking assembly 502, it can promote the physical separation of the two-layer packaging bag, and if the air nozzle 5041 of the air blowing assembly 504 is arranged between the bag taking assembly 502 and the packaging bag stacking station, it can buffer the lower packaging bag separated from the third adsorption unit 5013, so that the third adsorption unit 5013 is smoothly separated, and the lower packaging bag falls smoothly to the packaging bag stacking station. Of course, if the air nozzle 5041 of the air blowing assembly 504 can act on the above two places, it can promote separation and also buffer the falling of the packaging bag.

[0162] In addition, the bag taking mechanism 500 further comprises a positioning assembly 505, which is installed on the packaging bag stacking station (such as the mounting frame of the bag taking assembly 502 or the rack 400 of the whole machine), and is used to position the adhered lower packaging bag after separation. That is, the packaging bag can be limited or positioned when the air nozzle 5041 acts, so as to prevent the packaging bag from deviating too much from the packaging bag stacking station during falling, and to affect the continuous action. Of course, the positioning assembly 505 can also have the function of edge alignment, that is, the stacking pile is aligned, so as to facilitate the accuracy of continuous grabbing operation. The structure of edge alignment can be to configure a push rod that can move normally at both sides of the packaging bag stacking pile. The axial direction of the push rod is consistent with the stacking direction of the packaging bag. When the push rod moves towards the packaging bag stacking pile under the action of the linear motion mechanism, the edges of the packaging bag stacking pile are aligned.

[0163] In some embodiments, in order to fully and stably adsorb the uppermost packaging bag, the first adsorption unit 5023 is provided in plurality, the plurality of first adsorption units 5023 are installed on the surface of the first execution part 5022 near the side of the packaging bag stacking position, and the plurality of first adsorption units 5023 form an array pattern corresponding to the corners of the packaging bag, that is, the plurality of first adsorption units 5023 synchronously adsorb the corners of the packaging bag, thereby achieving the purpose of fully and stably adsorbing. For example, in the present embodiment, the first execution part 5022 is an I-shaped frame, the size of which matches the size of the packaging bag. The size of the I-shaped frame can be changed by telescopic adjustment according to different packaging bag models. The first adsorption unit 5023 is formed on the lower surface of each end of the I-shaped frame. After the four first adsorption units 5023 are vertically moved, they can adsorb the four corners of the packaging bag.

[0164] In addition, in the present embodiment, in order to smoothly transfer the packaging bag by the bag dragging assembly 503, especially when the transfer distance is large, the bag dragging assembly 503 can have a corresponding structural basis. The second driving part 5031 is a bag dragging cylinder, and the second execution part 5032 is a swing arm. One end of the swing arm is hinged to an external platform (for example, the rack 400), and the other end is integrated with the second adsorption unit 5033. The second adsorption unit 5033 can be a flexible adsorption assembly or a rigid clamping assembly as described above. Taking the finger cylinder clamping as an example, the side of the packaging bag can be stably clamped and adsorbed. The telescopic end of the bag dragging cylinder is hinged to the middle of the swing arm, so that the swing arm can reciprocate along the hinged direction. That is, the bag dragging assembly 503 adopts the form of a swing arm, which can have a larger distance transfer structure condition or structural basis.

[0165] On the basis of the technical scheme, in order to make the packaging bag more easily adsorbed during the swing transfer, the axial direction of the swing arm and the adsorption direction of the second adsorption unit 5033 form an included angle, which is less than 80°. The purpose is to facilitate the clamping and adsorption of the second adsorption unit 5033 when the first adsorption unit 5023 adsorbs the packaging bag and the swing arm swings to the position close to the packaging bag. After the swing arm swings to the transfer position, due to the existence of the included angle, the packaging bag can be placed obliquely on the transfer position, that is, the side of the packaging bag clamped first is placed on the transfer position before the side not clamped, which can facilitate the action of the remaining components on the first placed side, and then the other side naturally falls down, thereby achieving the purpose of effective positioning.

[0166] The packaging bag taking machine 1000 further comprises a rack 400, the taking mechanism 500 is mounted on the rack 400, for example, the taking assembly 502 is detachably connected with the rack 400 through an adjustable support or a fixed support, the bag suction assembly 501 can be detachably connected with the rack 400 through an adjustable support, so as to realize the adjustment of the relative position of the bag suction assembly 501, and the bag dragging assembly 503 is connected with the rack 400 through a hinge, so as to realize the reciprocating swing.

[0167] The rack 400 is provided with a first stacking station P1 for placing the packaging bags, and the taking mechanism 500 is mounted on the rack 400 between the first stacking station P1 and the bag conveying table 211, so as to transfer the packaging bags in the first stacking station P1 to the bag conveying table 211.

[0168] The working principle of the automatic material packaging system is as follows:

[0169] ①Taking the packaging bag: after the packaging bags in the first stacking station P1 are preliminarily aligned, the taking assembly 502 starts to act, the first suction unit 5023 controls the edge corner of the uppermost packaging bag to perform the suction action, when the packaging bag is sensed to form the adhesion, the bag suction assembly 501 immediately acts, and the third suction unit 5013 forms the suction with the adhesion packaging bag to separate them. After the separation is completed, the bag dragging assembly 503 acts, that is, the rotating arm is controlled to rotate to the first stacking station P1, the second suction unit 5033 performs the clamping suction on the edge side of the packaging bag, and then the rotating arm is reset, so as to transfer the packaging bag from the first stacking station P1 to the bag conveying table 211;

[0170] ②Bag conveying: the opening assembly 212 first opens the bag opening of the bag, at this time the support part 221 rotates until the first opening assembly 222 and the second opening assembly 223 are located in the inner cavity of the bag, then the bag stretching cylinder group 2223 drives the first support arm 2221 and the second support arm 2222 to move away from each other, so that the first bag stretching part 2224 and the second bag stretching part 2225 stretch the bag opening of the bag in the third direction, at this time the support part 221 reversely rotates to drive the first support arm 2221 and the second support arm 2222 to rotate synchronously, thereby driving the bag to move synchronously, in the process of movement, the second opening assembly 223 works, the first bag opening part 2231 and the second bag opening part 2232 move away from each other, the third bag opening part 2233 and the fourth bag opening part 2234 respectively move away from each other in the fourth direction, thereby stretching the bag in the fourth direction until the support part 221 rotates to the bag being sleeved on the discharging cylinder 130, at this time the clamping assembly 150 works, the first clamping arm 151 and the second clamping arm 152 clamp the bag on the discharging cylinder 130, then the first opening assembly 222 and the second opening assembly 223 reset, the support arm rotates by a certain angle until the first opening assembly 222 and the second opening assembly 223 are separated from the inner cavity of the bag, then the bag stretching cylinder group 2223 is stretched by a certain angle for giving way, after giving way, the support arm rotates forward to drive the first support arm 2221 and the second support arm 2222 to enter the next bag to be filled (the bag opened by the opening assembly 212);

[0171] ③Material conveying: first, the auger mechanism 310 rotates, conveying the material while driving the material loosening part to rotate, using the first blade group and the second blade group to rotate to scatter the material entering the auger mechanism 310, at this time, part of the material is discharged from the discharge port into the discharging cylinder 321, since the cutoff door 322 is in the open state, the material falls into the weighing mechanism 330 after passing through the inner cavity of the discharging cylinder 321 due to gravity, the weighing sensor detects the weight data in real time, when the weight of the material in the weighing mechanism 330 reaches the threshold value, the central control system controls the driving cylinder 326 to move, thereby driving the driving shaft 324 to rotate, driving the cutoff door 322 to rotate to be parallel to the ground, cutting off the material in the discharging cylinder 321; then the cutoff door 322 in the weighing mechanism 330 opens, the material enters the bag clamped on the discharging cylinder 130, then the turntable 120 rotates the parts to repeat the work. When the bag leaves the discharging cylinder 130, first, the first cylinder drives the first clamping arm 151 and the second clamping arm 152 to move away from each other, at the same time, the second cylinder drives the first bag stretching hook 153 and the second bag stretching hook 154 to move away from each other, at this time the bag descends under the action of gravity, the first bag stretching hook and the second bag stretching hook 154 stretch the bag opening straight;

[0172] (4) The packaging bag is sewn: the packaging bag falling along with gravity falls on the conveying component to be conveyed, and then is sewn by the sewing component.

[0173] In summary, the application has high automation degree, greatly improves work efficiency, reduces excessive labor loss, and is conducive to realizing automatic production.
