Description

Technical Field

[0001] This application relates to the technical field of automatic packaging equipment, and in particular to an automatic packaging production line for yeast powder. Background Technology

[0002] Currently, the packaging of yeast powder in the industry mainly relies on manual processes such as bagging, filling, and sewing. This method has extremely low automation, and because yeast powder has a very fine particle size, is lightweight, and easily disperses, the high-speed feeding and filling process generates a large amount of dust in the workshop, seriously endangering the respiratory health of operators. Furthermore, manual operation is prone to error, and a large amount of yeast powder dispersed during filling adheres to the inner wall of the packaging bag opening. During subsequent bag sewing or sealing processes, the yeast powder trapped between the seam and the bag body forms a fatal "powder trapping" phenomenon, leading to incomplete sealing and air leakage. This makes the highly biologically active yeast powder extremely susceptible to moisture absorption and clumping during subsequent storage and transportation, as well as contamination by other microorganisms, ultimately resulting in large-scale microbial inactivation or spoilage. Summary of the Invention

[0003] Therefore, it is necessary to provide an automated packaging line for yeast powder to address the problems of low automation, harm to personnel health, and impact on the packaging quality of yeast powder.

[0004] This application proposes an automated packaging production line for yeast powder, which includes:

[0005] A bag supply device, wherein the bag supply device is used to supply packaging bags one by one;

[0006] A bag opening device is located downstream of and connected to the bag supply device, and is used to open the packaging bag.

[0007] A filling device is located downstream of and connected to the bag opening device, and is used to fill the opened packaging bag with yeast powder.

[0008] A sealing device, located downstream of and connected to the filling device, is used to seal the opening of the packaging bag after the yeast powder has been filled to obtain yeast powder packaging; and

[0009] A palletizing device is located downstream of and connected to the sealing device, and is used to palletize the yeast powder packaging.

[0010] This automated packaging line for yeast powder is applied to production scenarios involving the automatic packaging of yeast powder, replacing traditional manual labor to improve efficiency and protect personnel safety. Specifically, during production, the bag feeding device first supplies packaging bags one by one to the bag opening device. The bag opening device then opens the bag, creating a pre-filling preparation state. Next, the filling device takes the opened bag and fills it with yeast powder until it is full. Then, the bags containing the predetermined weight of yeast powder are sent to the sealing device, which seals the bag opening to obtain a tightly sealed package of yeast powder. Finally, the bags of yeast powder are sent to the palletizing device for neat stacking, facilitating subsequent retrieval or transportation. Therefore, it can be seen that the automatic packaging production line for yeast powder in this solution can realize the fully automated packaging operation of yeast powder without human intervention, reducing the intensity of manual labor and lowering labor costs. At the same time, it effectively avoids the dust generated by the yeast powder being blown up, which may harm the health of personnel. Furthermore, the high-precision coordinated operation of each piece of equipment effectively solves the problem of large errors in manual operation and prevents yeast powder from adhering to the inner wall of the bag opening and causing "powder trapping" phenomenon, which would lead to the yeast powder in the packaging bag being contaminated by miscellaneous bacteria and affecting the quality.

[0011] The technical solution of this application will be further described below:

The second shaping belt is mounted on the second rotating mechanism and can rotate. A shaping channel is formed between the first shaping belt and the second shaping belt, and they can rotate synchronously and in the same direction.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] See Figure 1 This application illustrates an automatic packaging production line 100 for yeast powder, which includes a bag feeding device 10, a bag opening device 20, a filling device 30, a bag sealing device 40, and a palletizing device 50.

[0035] The bag feeding device 10 is used to supply packaging bags one by one; the bag opening device 20 is located downstream of the bag feeding device 10 and connected to the bag feeding device 10, and the bag opening device 20 is used to open the packaging bags; the filling device 30 is located downstream of the bag opening device 20 and connected to the bag opening device 20, and the filling device 30 is used to fill the opened packaging bags with yeast powder; the bag sealing device 40 is located downstream of the filling device 30 and connected to the filling device 30, and the bag sealing device 40 is used to seal the bag opening of the packaging bags after the yeast powder has been filled to obtain yeast powder packaging; the palletizing device 50 is located downstream of the bag sealing device 40 and connected to the bag sealing device 40, and the palletizing device 50 is used to palletize the yeast powder packaging.

[0036] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The automatic packaging production line 100 for yeast powder of this solution is applied to the production scenario of automatic packaging of yeast powder, replacing the traditional manual operation method, achieving the effect of improving quality and efficiency while protecting personnel safety. Specifically, during production, the bag feeding device 10 first supplies packaging bags one by one to the bag opening device 20. After obtaining the packaging bags, the bag opening device 20 opens the bag opening to form a pre-filling preparation state; then, the filling device 30 obtains the opened packaging bags and fills the bags with yeast powder until they are full; then, the packaging bags containing a predetermined weight of yeast powder are sent to the bag sealing device 40, which seals the bag opening to obtain a tightly sealed yeast powder package; finally, the bags of yeast powder are sent to the palletizing device 50 for neat stacking, facilitating subsequent retrieval or transportation.

[0037] Therefore, it can be seen that the automatic packaging line 100 for yeast powder in this solution can realize the fully automated packaging operation of yeast powder without human intervention, reducing the intensity of manual labor and lowering labor costs. At the same time, it effectively avoids the dust generated by the yeast powder being blown up, which may harm the health of personnel. Furthermore, the high-precision coordinated operation of each piece of equipment effectively solves the problem of large errors in manual operation and prevents yeast powder from adhering to the inner wall of the bag opening and causing "powder trapping" phenomenon, which would lead to the yeast powder in the packaging bag being contaminated by miscellaneous bacteria and affecting the quality.

[0038] Please continue reading. Figure 1 It should be noted that, where site conditions permit, the bag feeding equipment 10, bag opening equipment 20, filling equipment 30, bag sealing equipment 40 and palletizing equipment 50 are arranged in a straight line. By shortening the spacing between adjacent equipment, the material conveying efficiency is improved, which in turn helps to improve packaging production efficiency.

[0039] In one embodiment, the bag supply device 10 includes a bag storage bin, a bag retrieval mechanism, and a bag conveying mechanism. The bag retrieval mechanism is located between the bag storage bin and the bag conveying mechanism and is used to transfer the packaging bags in the bag storage bin one by one to the bag conveying mechanism. The bag conveying mechanism is connected to the bag opening device 20.

[0040] Specifically, the bag storage unit is used to store multiple folded packaging bags, such as stacked bags, saving storage space and ensuring neat arrangement, which facilitates the bag-retrieving mechanism to retrieve bags one by one. The bag-retrieving mechanism can adopt structures such as grippers or suction cups, which can reliably retrieve packaging bags one by one from the storage unit and transfer them to the bag conveying mechanism. The bag conveying mechanism then transports the packaging bags to the bag opening device 20, realizing automatic bag feeding without manual intervention.

[0041] The bag opening device 20 may include a first adsorption mechanism and a second adsorption mechanism. The first adsorption mechanism and the second adsorption mechanism are arranged opposite each other at intervals. After the packaging bag is fed between the two, the first adsorption mechanism and the second adsorption mechanism respectively adsorb and fix the opposite sides of the packaging bag, and then pull them in the direction away from each other, thereby opening the bag opening.

[0042] Please continue reading. Figure 1 Furthermore, in one embodiment, the automatic packaging line 100 for yeast powder also includes a bag opening fixing device 20a. The bag opening fixing device 20a is located downstream of the bag opening device 20 and is connected to both the bag opening device 20 and the filling device 30. The bag opening fixing device 20a is used to keep the packaging bag in an open position. By keeping the bag opening of the packaging bag open, the filling device 30 can continuously and safely fill the packaging bag with yeast powder, preventing the packaging bag from loosening and causing yeast powder leakage.

[0043] In actual production, due to the unique fermentation aroma of the yeast powder, it is very easy to attract a large number of live yeast insects (such as brewing bark beetles, black mealworms, etc.) to gather and fly in the packaging workshop. The packaging production line in traditional technology cannot prevent the yeast insects from mixing into the packaging bag at the moment of filling and sewing, thus forming serious biological foreign matter contamination in the finished product, directly destroying the purity of the liquor fermentation.

[0044] Please continue reading. Figure 2To address the aforementioned issues, in one embodiment, the automatic packaging line 100 for yeast powder further includes a protective cover 60 and a yeast insect removal device 60a. The protective cover 60 is installed outside the bag supply device 10 and the bag opening device 20, while the yeast insect removal device 60a is installed inside the protective cover 60 and works in conjunction with the bag opening device 20. The yeast insect removal device 60a is used to remove yeast insects from the packaging bags after the bag opening is opened. First, the protective cover 60, which covers the bag supply device 10 and the bag opening device 20, can block most yeast insects from the environment, preventing a large number of yeast insects from flying into the packaging bags after the bag opening is opened, thus affecting the quality of the yeast powder subsequently filled. Second, even if a small number of yeast insects fly into the packaging bags through gaps, the yeast insect removal device 60a can clean these few yeast insects before the yeast powder is filled, ensuring the cleanliness of the packaging bags.

[0045] Specifically, based on the above embodiments, the insect removal device 60a includes a first support, a second support, a blowing mechanism, a suction mechanism, and an insect collection box. The blowing mechanism is mounted on the protective cover 60 via the first support and is used to blow airflow into the packaging bag. The suction mechanism is mounted on the protective cover 60 via the second support and is arranged close to the bag opening of the packaging bag, and the suction mechanism is connected to the insect collection box.

[0046] The first bracket is used to mount and position the blowing mechanism on the inner wall of the protective cover 60, and the second bracket is used to mount and position the suction mechanism on the protective cover 60. Before the actual filling of the yeast powder, the blowing mechanism is activated to spray high-pressure clean airflow into the packaging bag, which can blow up any yeast insects, eggs, or other foreign objects that may remain in the bag and carry them to the bag opening. Then, the suction mechanism generates negative pressure suction to suck up and collect these yeast insects, eggs, or other foreign objects, thereby achieving the effect of cleaning the environment inside the bag. After this, the filling equipment 30 can normally fill the packaging bag with yeast powder, ensuring the quality of the yeast powder.

[0047] Specifically, the blowing mechanism includes a high-pressure air source, a solenoid valve, an air pipe, and a nozzle. One end of the air pipe is connected to the high-pressure air source, and the other end is connected to the nozzle. The solenoid valve is installed on any one of the high-pressure air source, the air pipe, and the nozzle to realize the on / off control of the high-pressure airflow ejected from the nozzle.

[0048] Furthermore, the nozzle includes a rotary driver and a nozzle head. The nozzle head is driven and connected to the rotary driver and can rotate circumferentially under the drive of the rotary driver, so that the high-pressure airflow ejected from the nozzle head can effectively and comprehensively sweep the entire inner wall of the packaging bag, avoiding the existence of residual dead corners that would affect the quality of the yeast powder that is subsequently monitored.

[0049] In addition, the suction mechanism includes a negative pressure fan, a suction pipe, and a suction head. One end of the suction pipe is connected to the negative pressure fan, and the other end is connected to the suction head. The air outlet of the negative pressure fan is connected to the insect collection box. The negative pressure fan draws air at high speed to generate negative pressure suction at the suction head, which in turn sucks in foreign objects such as asparagus larvae that are raised to the bag opening and transfers them to the insect collection box for temporary storage.

[0050] Preferably, the suction head is a ring tube with multiple suction ports that surround the edge of the bag opening, thereby ensuring that foreign objects such as insects raised from all directions can be thoroughly and effectively sucked up and removed, improving cleaning efficiency.

[0051] Please continue reading. Figure 1 Furthermore, based on any of the above embodiments, the automatic packaging production line 100 for yeast powder also includes a transfer device 30a. The transfer device 30a is disposed between the filling device 30 and the sealing device 40, and is used to transfer the packaged bags after filling from the filling device 30 to the sealing device 40. The packaged bags after filling with yeast powder can be automatically transferred to the sealing device 40 through the transfer device 30a without human intervention, realizing automated production and improving efficiency.

[0052] For example, the transfer device 30a consists of a rotatable power mechanism and a transfer robot. After the transfer robot grabs a packaging bag filled with yeast powder but not yet sealed from the filling device 30, the power mechanism drives the transfer robot to rotate the packaging bag to the sealing device 40, and the transfer robot can then release the packaging bag into the sealing device 40.

[0053] The bag sealing equipment 40 includes a sealing platform, a positioning and pressing component, and a sealing execution component. After the packaging bag is fed into the sealing platform by the transfer robot, the positioning and pressing component aligns the bag opening and presses it tightly. Then, the sealing execution component seals the bag opening.

[0054] Optionally, the sealing component can be any one of the following, including but not limited to heat sealing components and sewing components. The specific choice can be made flexibly according to actual needs, and no specific limitation is made here.

[0055] In one embodiment, the automatic packaging production line 100 for yeast powder also includes a bag-inverting device 70 and a shaping device 80. The bag-inverting device 70 is located downstream of the bag-sealing device 40, and the shaping device 80 is located downstream of the bag-inverting device 70.

[0056] The shaping equipment 80 includes a first rotating mechanism, a second rotating mechanism, a first shaping belt, and a second shaping belt. The first rotating mechanism and the second rotating mechanism are arranged longitudinally at intervals. The first shaping belt is mounted on the first rotating mechanism and can rotate. The second shaping belt is mounted on the second rotating mechanism and can rotate. A shaping channel is formed between the first shaping belt and the second shaping belt, and they can rotate synchronously and in the same direction. The shaping channel is used for the yeast powder packaging to enter for shaping treatment.

[0057] Normally, packaging bags are upright with the opening facing upwards before sealing. However, in subsequent stacking processes, they are usually required to be horizontal. Therefore, after the sealing process in the sealing equipment 40 produces a tightly sealed yeast powder package, it is immediately transferred to the bag-inverting equipment 70. The bag-inverting equipment 70 pushes the yeast powder package horizontally. However, considering that the yeast powder is unevenly distributed inside the packaging bag at this point, resulting in local bulges and collapses, which is not conducive to subsequent stacking, the horizontally laid yeast powder package is then immediately sent to the shaping channel of the shaping equipment 80. At this time, the first and second rotating mechanisms rotate synchronously in the same direction, driving the first and second shaping belts to rotate synchronously in the same direction, forming a squeezing and flattening effect on the yeast powder package, ensuring the flat shape of the yeast powder package and the stability of subsequent stacking.

[0058] Please continue reading. Figure 1 Furthermore, based on the above embodiments, the automatic packaging production line 100 for yeast powder also includes a pallet storage 90 and a pallet conveying device 90a. The pallet storage 90 is connected to the pallet conveying device 90a, and the pallet conveying device 90a is connected to the pallet stacking device 50. The pallet conveying device 90a transports pallets from the pallet storage 90 to the pallet stacking device 50, allowing the yeast powder packaging to be neatly arranged in the pallets. This ensures that during subsequent stacking, the pallets are stacked vertically, providing load-bearing capacity to prevent the yeast powder packaging from being damaged by pressure. It also facilitates the subsequent retrieval of yeast powder packaging from the entire pallet.

[0059] For example, the pallet can be any type of pallet, including but not limited to wooden pallets, plastic pallets, and metal pallets, and can be selected flexibly according to actual needs.

[0060] In one embodiment, the automated packaging line 100 for yeast powder also includes a pallet storage device 90b. The pallet storage device 90b includes a storage rack, a robotic arm, and a gripper. The storage rack has multiple storage locations arranged longitudinally. The robotic arm is mounted on the storage rack, and the gripper is connected to the robotic arm. The robotic arm provides the freedom of movement to deliver pallets from the palletizing equipment 50 one by one into different storage locations. In this way, multiple pallets filled with yeast powder packaging can be neatly stacked in the storage rack, achieving centralized storage and management.

[0061] It should be noted that the temporary storage rack is a three-dimensional frame with a cuboid structure. It has an opening on one side in the vertical direction, which is connected to each storage location, so that the robotic arm can drive the gripper to put the yeast powder into the storage location or take it out of the storage location.

[0062] The storage location is equipped with two parallel tracks spaced apart on the left and right. These tracks are designed to slide against the bottom of the pallet, reducing the sliding contact area and sliding resistance, and improving the smoothness of the pallet entering and leaving the storage location.

[0063] Furthermore, based on the above embodiments, the automatic packaging production line 100 for yeast powder also includes a material handling device 90c, which is located downstream of the pallet storage device 90b. The material handling device 90c is used to retrieve pallets of yeast powder packaging from the storage location. For example, the material handling device 90c can be a forklift, AGV, etc.

[0064] In addition, a 90d finished product warehouse can be configured to temporarily store the yeast powder packaging for subsequent loading and transportation.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
