Description

Technical Field

[0001] This invention relates to the field of mechanical automation, and more specifically to a sealed automatic unpacking and unloading system for bagged products. Background Technology

[0002] The raw materials used in chemical production are mostly solid powders or granules. These raw materials need to be packaged before transportation or use. The packaging forms usually include small bags, ton bags, cans, drums and other forms. For small bags, which are generally 10-30 kg (depending on the specific gravity), the bags are often made of flexible materials, making them difficult to handle and open by machinery. Therefore, these small bags are usually opened manually. There are two methods of manual unpacking: destructive unpacking and protective unpacking. However, no matter which method is used, dust is inevitably generated, which is harmful to the health of workers. In addition, manual unpacking is labor-intensive for workers, resulting in high labor costs for manufacturers and a greater loss of raw materials.

[0003] Therefore, there is an urgent need for an automatic unpacking system for small-packaged goods that can automatically unpack and feed materials while avoiding the loss and waste of raw materials. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems of manual unpacking of bag packaging in existing technologies, such as high costs and dust generation. This invention provides a closed, automatic unpacking and unloading system for bag packaging. In this system, the bag packaging is automatically unpacked and unloaded on an unpacking and unloading machine within a sealed chamber. The unpacking and unloading machine uses a gripping hook on a gripping trolley to directly pierce the bag packaging and, in conjunction with a rotatable roller below, stably grips the bag packaging. A conveying mechanism drives the gripping trolley to move to one side along a preset direction, while the roller rotates and a blade cuts at least one opening in the bag packaging, allowing the raw materials inside to leak out and ultimately be collected in a material collection tank below the unpacking and unloading machine.

[0005] To achieve the above objectives, the present invention provides a sealed automatic unpacking and unloading system for bag packaging, comprising: a sealed chamber; an unpacking and unloading machine fixedly connected to the sealed chamber; and a material collection tank disposed below the unpacking and unloading machine; wherein the unpacking and unloading machine comprises: a bag-grabbing trolley with a bag-grabbing hook that can pierce the bag packaging when extended; a conveying mechanism for driving the bag-grabbing trolley to move in a preset direction; a roller disposed below the bag-grabbing trolley and capable of rotation; a first driving device for driving the roller to rotate; and a blade fixedly connected to the roller for cutting the bag packaging.

[0006] Preferably, the conveying mechanism includes: a transmission screw, which is connected to the bag-grabbing trolley; and a second driving device for driving the transmission screw to move the bag-grabbing trolley along a preset direction.

[0007] Preferably, the unpacking and unloading machine further includes: a vibrating roller, which is disposed below the bag gripping trolley and can rotate, for vibrating the bag packaging.

[0008] Preferably, the vibrating roller is provided with prismatic teeth of different heights.

[0009] Preferably, the system also includes a dust removal system connected to the sealed chamber, the dust removal system comprising an induced draft fan and a bag filter.

[0010] Preferably, the idler roller is provided with coarse threads.

[0011] Preferably, there are two coarse threads symmetrically arranged, and the two coarse threads rotate in opposite directions.

[0012] Preferably, it also includes a feeding conveyor device capable of lifting the bag packaging to a preset height above the idler roller.

[0013] Preferably, the bag-grabbing trolley is equipped with a grid, and the bag-grabbing hook can pass through the grid to pierce the bag packaging.

[0014] Preferably, the sealed chamber has a waste bag outlet facing downwards on one side.

[0015] It is easy to see from the above technical solution that the advantages of the present invention are:

[0016] 1. The unpacking and unloading machine is set up in a sealed chamber to ensure that there is no dust or waste of raw materials during the entire process.

[0017] 2. The grab hook directly pierces the bag packaging and, together with the rotatable roller below, can stably grab the bag packaging.

[0018] 3. The feeding conveyor can lift the bag packaging to a preset height to compensate for the height difference between the idler roller and the bag packaging during feeding.

[0019] 4. The vibrating roller is located below the bag-grabbing trolley and can rotate, which can vibrate the bag packaging to improve the unloading effect.

[0020] 5. The ribbed teeth of different heights on the vibrating roller make it easier for the raw materials inside the bag to leak out.

[0021] 6. The idler rollers are equipped with coarse threads, which can increase the friction between the idler rollers and the bag packaging.

[0022] 7. Two coarse threads are symmetrically arranged, and the two coarse threads rotate in opposite directions. When rotating, they can push the bag packaging to the center position, making it easier to grasp and improving the stability of the overall unpacking and unloading.

[0023] 8. The bag grabbing trolley is equipped with a grid. The grabbing hook can pass through the grid to pierce the bag packaging in order to grab the bag packaging. When the grabbing hook retracts, the grid can block the bag packaging and the grabbing hook, so that the bag packaging will fall off by its own weight after unloading. Attached Figure Description

[0034] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0035] It should be noted that similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures, or the orientation or positional relationship commonly used when the product of this application is in use. They 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. Therefore, they should not be construed as limitations on this application.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] It should be noted that, in the embodiments of this application, "cutting" refers to using a blade to cut at least one opening in the bag packaging so that the solid powder or granular raw materials inside the bag packaging can leak out, thereby achieving the purpose of automatic unloading.

[0038] In this embodiment, "vibration" refers to the frequent contact of the bag packaging with the vibration roller 206 from the bottom, combined with the bag packaging's own weight, to make the solid powdery or granular raw materials inside the bag packaging leak out as much as possible, thereby improving the unloading effect.

[0039] The "coarse thread" used in this application embodiment refers to a thread with a larger pitch. The coarse thread in this application embodiment is used to increase the friction between the idler roller 203 and the bag packaging. Considering that the raw materials in the bag packaging are solid powder or granules and have a certain size, the coarse thread with a larger pitch allows the raw materials to pass through the bag body and abut against the threads of the coarse thread, thereby obtaining a larger contact area with the bag packaging and improving the conveying effect of the idler roller 203 on the bag packaging.

[0040] The “grid” used in this application refers to a blocking member with a through section at the top and bottom. The shape of the through section can be a common strip, or a parallelogram, a circle, or an irregular shape. When the grab hook extends, it can pass through the through section of the grid to pierce the bag packaging, so as to achieve the purpose of grabbing the bag packaging. When the grab hook retracts, the grid can block the bag packaging and the grab hook, so that the bag packaging after unloading can fall off by its own weight.

[0041] In this embodiment of the application, "the material collection tank 300 is located below the unpacking and unloading machine 200" means that, with the ground as the standard, the distance from the material collection tank 300 to the ground is less than the distance from the unpacking and unloading machine 200 to the ground, that is, the material collection tank 300 is closer to the ground than the unpacking and unloading machine 200.

[0042] In this embodiment of the application, "the idler roller 203 is located below the bag-grabbing trolley 201" means that, with the ground as the standard, the distance from the idler roller 203 to the ground is less than the distance from the bag-grabbing trolley 201 to the ground, that is, the idler roller 203 is closer to the ground than the bag-grabbing trolley 201.

[0043] In this embodiment of the application, "the vibrating roller 206 is located below the bag-grabbing trolley 201" means that, with the ground as the standard, the distance from the vibrating roller 206 to the ground is less than the distance from the bag-grabbing trolley 201 to the ground, that is, the vibrating roller 206 is closer to the ground than the bag-grabbing trolley 201.

[0044] The following will be combined with the appendix Figure 1-3 The technical solution provided in this application is described.

[0045] Example 1:

[0046] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure. Figure 2 This is a structural schematic diagram of the unpacking and unloading machine 200. Figure 3 This is a structural schematic diagram of the unpacking and unloading machine 200 from another perspective, that is, relative to... Figure 2 A schematic diagram from another angle perpendicular to the viewpoint.

[0047] This application provides a sealed automatic unpacking and unloading system for bag packaging, including a sealed chamber 100, an unpacking and unloading machine 200, and a material collection tank 300. The unpacking and unloading machine 200 is fixedly connected inside the sealed chamber 100 for unpacking and unloading the bag packaging. The material collection tank 300 is located below the unpacking and unloading machine 200 to facilitate the collection of raw materials inside the bag packaging. Further, the unpacking and unloading machine 200 includes a gripping trolley 201, a conveying mechanism 202, a roller 203, a first driving device 204, and a blade 205. The gripping trolley 201 is equipped with a gripping hook 201a, which can pierce the bag packaging when extended. The conveying mechanism 202 drives the gripping trolley 201 to move in a preset direction. The roller 203 is located below the gripping trolley 201 and can rotate. The first driving device 204 drives the roller 203 to rotate. The blade 205 is fixedly connected to the roller 203 for cutting the bag packaging. Figure 1 As shown, the preset direction in this embodiment is the horizontal direction, that is, the conveying mechanism 202 can drive the bag-grabbing trolley 201 to move in the horizontal direction. Obviously, the preset direction can also have an inclination angle, which can achieve the same purpose as this embodiment, that is, it should also be within the protection scope of this embodiment. The first driving device 204 in this embodiment can be a motor, etc.

[0048] Through the above technical solution, the bag packaging is automatically unpacked and unloaded on the unpacking and unloading machine 200 inside the sealed chamber 100. The sealed chamber 100 ensures that there is no dust or waste of raw materials during the entire process. The unpacking and unloading machine 200 directly pierces the bag packaging with the grabbing hook 201a on the grabbing trolley 201 and works in conjunction with the rotatable roller 203 below to stably grab the bag packaging. The specific grabbing timing can be selected by touching the limit switch or photoelectric sensor. The conveying mechanism 202 drives the grabbing trolley 201 to move to one side along the preset direction. At the same time, the first driving device 204 drives the roller 203 to rotate. The blade 205 on the roller 203 cuts at least one opening in the bag packaging, allowing the solid powder or granular raw materials inside the bag packaging to leak out and finally be collected in the material collection tank 300 below the unpacking and unloading machine 200.

[0049] In a preferred embodiment, such as Figure 2 As shown, the conveying mechanism 202 includes a transmission screw 202a and a second driving device 202b. The transmission screw 202a is connected to the bag-grabbing trolley 201. The second driving device 202b can drive the transmission screw 202a to move the bag-grabbing trolley 201 along a preset direction. In this embodiment, the transmission screw 202a drives the bag-grabbing trolley 201 to move. The transmission screw 202a has high selection accuracy and stable transmission. It can be used in conjunction with photoelectric sensors and other automation systems to achieve high-precision fully automatic completion of the entire process.

[0050] In a preferred embodiment, a dust removal system (not shown) connected to the sealed chamber 100 is also included. The dust removal system includes an induced draft fan and a bag filter. In this embodiment, the dust generated during the entire process is drawn into the bag filter by the induced draft fan of the dust removal system, and the lost material can also be recovered, and the exhaust gas is discharged in compliance with standards.

[0051] In a preferred embodiment, please refer to Figure 1 It also includes a feeding conveyor 400, which can lift the bag packaging to a preset height above the idler roller 203. In this embodiment, the feeding conveyor 400 can lift the bag packaging to a preset height to compensate for the height difference between the idler roller 203 and the bag packaging during feeding. Specifically, the feeding conveyor 400 in this application adopts a belt conveyor, which is suitable for the transmission of bag packaging, is stable, and has low cost.

[0052] Example 2:

[0053] The only difference between this embodiment and Embodiment 1 is that it also includes a vibrating roller 206, which improves the unloading effect. Other technical solutions are the same as or similar to Embodiment 1, so this embodiment will not be described further.

[0054] like Figure 2 As shown, the unpacking and unloading machine 200 also includes a vibrating roller 206. The vibrating roller 206 is located below the bag gripping trolley 201 and can rotate. It can vibrate the bag packaging. In this embodiment, the vibrating roller 206 makes frequent contact with the bag packaging from the bottom and vibrates it in combination with the bag packaging's own weight, so that the solid powder or granular raw materials inside the bag packaging can leak out as much as possible, thereby improving the unloading effect.

[0055] In a preferred embodiment, the vibrating roller 206 is provided with prism teeth (not shown) of different heights. The prism teeth of different heights can make the bag packaging move up and down more during the process, and the vibration amplitude and frequency are greater, which is more conducive to the leakage of raw materials inside the bag packaging.

[0056] Example 3:

[0057] The only difference between this embodiment and Embodiments 1 and 2 is that the idler roller 203 is also provided with coarse threads, which improves the conveying effect of the idler roller 203. Other technical solutions are the same as or similar to Embodiments 1 and 2, so this embodiment will not be described again.

[0058] In this embodiment, the idler roller 203 is provided with coarse threads (not shown). The coarse threads can increase the friction between the idler roller 203 and the bag packaging. It is particularly noteworthy that, considering that the raw materials in the bag packaging are solid powder or granules with a certain size, the coarse threads with a larger pitch can allow the raw materials to pass through the bag body and abut against the threads of the coarse threads, thereby obtaining a larger contact area with the bag packaging and further improving the conveying effect of the idler roller 203 on the bag packaging.

[0059] In a preferred embodiment, two coarse threads are symmetrically arranged, and the two coarse threads rotate in opposite directions. In this embodiment, when the two opposite coarse threads rotate, they can push the bag packaging to the center position, which facilitates its gripping and improves the overall stability of unpacking and unloading.

[0060] Example 4:

[0061] The only difference between this embodiment and Embodiments 1, 2 and 3 is that the bag-grabbing trolley 201 is equipped with a grid to facilitate the automatic removal of the unloaded bags. Other technical solutions are the same as or similar to Embodiments 1, 2 and 3, so this embodiment will not be described further.

[0062] In this embodiment, the bag-grabbing trolley 201 is equipped with a grid (not shown). The bag-grabbing hook 201a can pass through the grid to pierce the bag packaging in order to achieve the purpose of gripping the bag packaging. When the bag-grabbing hook 201a retracts, the grid can block the bag packaging and the bag-grabbing hook 201a, so that the bag packaging after unloading can fall off by its own gravity. Specifically, the timing of the retraction of the bag-grabbing hook 201a can be achieved by touching a limit switch or a photoelectric sensor. After the bag packaging falls off, the bag-grabbing trolley 201 returns to the initial position to prepare for the next cycle operation.

[0063] In a preferred embodiment, such as Figure 2 As shown, a waste bag outlet 101 is provided on one side of the sealed chamber 100 facing downwards. In this embodiment, after the bag packaging is unloaded, it is discharged from the waste bag outlet 101, realizing a fully automated process of unpacking and unloading the bag packaging.

[0064] In summary, it is evident from the above embodiments that this application provides a closed automatic unpacking and unloading system for bag packaging, used for fully automated unpacking and unloading of bag packaging in factories or laboratories. This improves the efficiency of the entire work process, avoids the high costs of manual unpacking, and eliminates dust generation and material waste throughout the process. During operation, the bag packaging is conveyed to the working position of the unpacking and unloading machine 200 by the feeding conveyor 400. The rollers 203 inside the unpacking and unloading machine 200 convey the bag packaging in a designated direction. Simultaneously, the second drive device 202 drives the transmission screw 202a to move the gripping trolley 201 above the bag packaging to prepare for gripping. During gripping, the gripping hooks 201 on the gripping trolley 201... A piercing hook 201 passes through the grid to grab the bag packaging. Once the grabbing is complete, the second drive device 202 continues to drive the transmission screw 202a to move the grabbing trolley 201 in the designated direction. At the same time, the first drive device 204 drives the idler roller 203 to rotate. The blade 205 on the idler roller 203 cuts at least one opening in the bag packaging, allowing the solid powder or granular raw materials inside the bag packaging to leak out and be collected in the material collection tank 300 below the unpacking and unloading machine 200. When the grabbing trolley 201 moves to the other end, the grabbing hook 201a retracts, and the grid blocks the bag packaging and the grabbing hook 201a, causing the unloaded bag packaging to fall off by its own weight and be discharged from the waste bag outlet 101.

[0065] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application also intends to include these modifications and variations.
