Abstract

The application discloses a hooking assembly, a hooking device and automatic unpacking equipment. The hooking assembly comprises a rack, a hook, an elastic member and a detection member. The rack is provided with a mounting hole. The hook is arranged in the mounting hole and is movably arranged along the height direction of the hooking assembly relative to the rack. One end of the hook arranged out of the mounting hole forms a hook portion, which is used for hooking a lifting lug of a ton bag. The elastic member is connected between the other end of the hook arranged out of the mounting hole and the rack. The detection member is installed on the rack and is located on the side of the hook away from the hook portion. When the hooking weight of the hook is greater than a preset value, the hook drives the elastic member to elastically deform and separates from the detection member, so that the pressure of the hook on the detection member is prevented from exceeding the range of the detection member. When the hooking weight of the hook is less than or equal to the preset value, the elastic member drives the hook to abut against the detection member. The detection member is used for detecting the pressure of the hook on the detection member, and the weight on the hook is accurately measured through the pressure of the hook on the detection member.

Description

Technical Field

[0001] This application relates to the field of ton bag unpacking technology, and in particular to a hook assembly, hook device and automatic unpacking equipment. Background Technology

[0002] Traditional automated bag-unpacking equipment uses sensors attached to hooks to weigh the ton bags. The sensors detect the hook's tension to determine if the bag is successfully hooked and the degree of emptying. However, due to the significant weight difference between full and empty ton bags, a large-range sensor is required to prevent the hook's tension from exceeding its maximum range when the bag is full. Large-range sensors, however, have low weighing accuracy and cannot accurately measure the weight of empty ton bags, making it impossible to determine the weight of any remaining material. Summary of the Invention

[0003] This application provides a hook assembly, hook device, and automatic unpacking equipment to solve the problem of not being able to determine the weight of residual material in ton bags.

[0004] In a first aspect, embodiments of this application provide a hook assembly, which includes a frame, a hook, an elastic element, and a detection element. The frame has a mounting hole. The hook passes through the mounting hole and is movably disposed relative to the frame along the height direction of the hook assembly. One end of the hook extending through the mounting hole forms a bent hook portion, which is used to hook the lifting lug of a ton bag. The elastic element connects the other end of the hook extending through the mounting hole to the frame. The detection element is mounted on the frame and located on the side of the hook away from the bent hook portion. When the hook's weight exceeds a preset value, the hook causes the elastic element to elastically deform and separate from the detection element. When the hook's weight is less than or equal to the preset value, the elastic element causes the hook to abut against the detection element. The detection element is used to detect the pressure exerted by the hook on the detection element.

[0005] In conjunction with the first aspect, in some implementations of the first aspect, the detection element includes a detection part and an adjustment part. The detection part is mounted on the frame, and the adjustment part is connected to the detection part. The adjustment part is used to separate from the hook when the hook weight is greater than a preset value, and to abut against the hook when the hook weight is less than or equal to the preset value. The protrusion length of the adjustment part relative to the detection part in the direction toward the hook is adjustable.

[0006] In conjunction with the first aspect, in some implementations of the first aspect, the hook includes a hook member, a connector, and an abutment member. The connector is movably inserted into the mounting hole. The hook member is fixedly connected to one end of the connector that extends out of the mounting hole. The end of the hook member away from the connector forms the hook portion. The abutment member is located at the other end of the connector that extends out of the mounting hole and is fixed relative to the connector. The elastic member is connected between the abutment member and the frame. When the hook weight is less than or equal to a preset value, the detection member is used to abut against the connector and / or the abutment member.

[0007] In conjunction with the first aspect, in some implementations of the first aspect, the abutment is fixedly connected to the connector, or the connector abuts against the side of the abutment opposite to the hook.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the hook assembly further includes a guide member, the guide member being fixedly connected to the frame, the abutment member being provided with a guide through hole, the guide member passing through the guide through hole, the extension direction of the guide member being parallel to the height direction of the hook assembly, and the elastic member being sleeved on the guide member.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, the abutment includes a base and an extension, the extension being connected to the side of the base facing the frame, the extension and the base enclosing an accommodating space, the elastic member being located within the accommodating space and elastically abutting between the base and the frame, the base being fixed relative to the connector.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the hook assembly further includes a bag detection component, which is mounted on the frame and used to detect whether the hook is hooked onto the lifting lug.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the frame includes a first crossbeam, a second crossbeam, and two side beams, the first crossbeam and the second crossbeam being respectively connected between the two side beams, the first crossbeam and the second crossbeam being spaced apart, the detection element being mounted on the second crossbeam, the hook being movably connected to the first crossbeam, the elastic element being elastically abutting between the first crossbeam and the hook, and / or, the elastic element being elastically connected between the second crossbeam and the hook.

[0012] Secondly, this application provides a hooking device, which includes a mounting base, a translation drive, and two hooking assemblies as described above. The translation drive and the two hooking assemblies are mounted on the mounting base. The translation drive is used to drive the two hooking assemblies to move closer to or further away from each other in the width direction of the hooking assemblies.

[0013] In conjunction with the second aspect, in some implementations of the second aspect, the hook-hanging device further includes a striking assembly. The striking assembly includes a striking drive, a transmission component, and a striking rod. The striking drive is mounted on the frame. The striking rod includes a striking portion and a connecting portion. The striking portion is rotatably connected to the frame, and the connecting portion is fixedly connected to the striking portion. One end of the transmission component is rotatably connected to the striking drive, and the other end of the transmission component is rotatably connected to the connecting portion. The striking drive is used to drive one end of the transmission component to move linearly, and to cause the other end of the transmission component to drive the connecting portion and the striking portion to rotate relative to the frame.

[0014] Thirdly, this application provides an automatic unpacking device, which includes a cabinet and a hook device as described above, the hook device being movably installed inside the cabinet.

[0015] The hook assembly, hook device, and automatic unpacking equipment provided in this application are based on the hook being movable relative to the frame along the height direction of the hook assembly. When the hook weight is greater than a preset value, the hook causes the elastic element to deform elastically and separate from the detection element. When the hook weight is less than or equal to the preset value, the elastic element causes the hook to abut against the detection element. The detection element is used to detect the pressure exerted by the hook on the detection element. On the one hand, when the hook weight is greater than the preset value, separating the hook from the detection element can prevent the pressure exerted by the hook on the detection element from exceeding the detection element's measurement range, thus avoiding damage to the detection element. On the other hand, when the hook weight is less than or equal to the preset value, the elastic element causes the hook to abut against the detection element. Since the elastic element is connected between one end of the hook that passes through the mounting hole and the frame, and the detection element is located on the side of the hook away from the bent part, the elastic force provided by the elastic element can partially offset the weight of the hook, so that the pressure exerted by the hook on the detection element is within the measurement range of the detection element. Therefore, a high-precision detection element can be selected. The elastic element, by applying pressure to the hook on the detection element, can accurately measure the weight hooked on the hook, thereby enabling precise measurement of the weight of residual material in the unloaded ton bag. On the other hand, when the hook assembly hooks a full ton bag, if the hook fails to hook the bag's lifting lug, the elastic element drives the hook to abut against the detection element. When the hook successfully hooks the bag's lifting lug, the weight of the ton bag causes the hook to deform elastically, separating it from the detection element. Thus, the detection element's measurement of the hook determines whether the hook has successfully hooked the bag's lifting lug, achieving automatic detection of whether the hook assembly has successfully hooked the bag. Furthermore, after the hook assembly successfully hooks the bag, the detection element measures the hook's weight to determine if the bag has been completely unloaded. This allows the automatic unpacking equipment to accurately weigh the ton bags, automatically detect successful hooking, and automatically detect whether the bag has been completely unloaded, improving the automation level of the automatic unpacking equipment, reducing manual intervention, and increasing its working efficiency and safety.

The scope of protection of this application shall be determined by the appended claims.

[0030] For the sake of accuracy, all references to direction in this article should be expressed in terms of direction. Figure 1 and Figure 3 For reference, "length direction X" refers to the direction in which the moving device 42 drives the ton bag 1a to move relative to the cabinet 1, that is, Figure 1 The left and right directions (where the positive X-axis is to the right); the term "width direction Y" refers to the opening and closing direction of the two hook components 230 in the hook device 2, that is...

The length (X), width (Y), and height (Z) directions can be customized based on the specific structure of the product and the viewing angle of the accompanying drawings; this application does not impose specific limitations. For ease of description, the terms "up," "down," "left," "right," "front," and "back" in this application are relative positions and do not constitute limitations on implementation. Specifically, the length (X) direction of the hook assembly 230 is parallel to the length (X) direction of the hook device 2 and the automatic unpacking device 100; the width (Y) direction of the hook assembly 230 is parallel to the width (Y) direction of the hook device 2 and the automatic unpacking device 100; and the height (Z) direction of the hook assembly 230 is parallel to the height (Z) direction of the hook device 2 and the automatic unpacking device 100.

[0031] Please see Figure 1 , Figure 1 This is a cross-sectional view of the automatic unpacking device 100 provided in this application embodiment. The automatic unpacking device 100 includes a cabinet 1 and a hook device 2. The hook device 2 is movably installed inside the cabinet 1 and is used to hook or release ton bags 1a. Thus, the automatic unpacking device 100 provided in this application embodiment, based on the movable installation of the hook device 2 inside the cabinet 1, enables the ton bags 1a to move between different functional areas within the cabinet 1, thereby improving the working efficiency of the automatic unpacking device 100.

[0032] In some embodiments, the cabinet 1 is provided with a feeding bin 110 and a bag-breaking bin 130. The feeding bin 110 and the bag-breaking bin 130 are set up independently of each other, thereby realizing the modular setting of the automatic unpacking equipment 100. This allows for flexible combination of various modules according to different customer needs, meeting the different needs of different customers, improving product flexibility, simplifying the production process, making production more efficient, and facilitating assembly, repair and maintenance.

[0033] In some embodiments, the automatic unpacking equipment 100 may further include a shaping device 3. The shaping device 3 is disposed in the feeding hopper 110 and is used to shape the shape of the ton bag 1a, thereby making the shape of the ton bag 1a regular and avoiding the problem that irregular shapes such as tilted or conical ton bags 1a will affect the hooking success rate of the hooking device 2 and cause the ton bag 1a to be unstable and damage other mechanical components, thereby improving the hooking success rate of the hooking device 2 and improving the safety and reliability of the automatic unpacking equipment 100.

[0034] The automatic unpacking device 100 may also include, but is not limited to, a lifting device 41, a moving device 42, and a bag-breaking device 5. The lifting device 41 is located within the feeding hopper 110 and is independently configured with respect to the hook device 2. The lifting device 41 is used to drive the ton bag 1a towards or away from the hook device 2 along the height direction Z of the automatic unpacking device 100. Of course, in some other embodiments, the lifting device 41 is connected to the hook device 2, and the lifting device 41 is used to drive the hook device 2 towards or away from the ton bag 1a along the height direction Z of the automatic unpacking device 100. The bag-breaking device 5 is located within the bag-breaking hopper 130 and is used to automatically unpack the ton bag 1a. The moving device 42 is located at the top of the cabinet 1 in the height direction Z of the automatic unpacking device 100 and is connected to the hook device 2. The moving device 42 is used to drive the hook device 2 to move along the length direction X of the automatic unpacking device 100. Specifically, the moving device 42 is used to drive the hook device 2 to move between the feeding hopper 110 and the bag-breaking hopper 130.

[0035] In some embodiments, the automatic unpacking device 100 may further include a conveying device 43. The conveying device 43 is disposed within the feed hopper 110 and located below the hook device 2. The conveying device 43 is used to convey the ton bag 1a to the lifting device 41 or the hook device 2.

[0036] In some embodiments, the automatic unpacking equipment 100 may further include an air shower device 45. The air shower device 45 is disposed inside the feed hopper 110 and is used to remove dust and microorganisms adhering to the surface of the ton bag 1a, ensuring that the unpacking process of the ton bag 1a is carried out in a clean environment, thereby reducing the risk of material contamination.

[0037] In some embodiments, the cabinet 1 is further provided with a bag collection bin 150. The bag collection bin 150 is located between the feeding bin 110 and the bag breaking bin 130, and is independently set up from the feeding bin 110 and the bag breaking bin 130. Of course, in some embodiments, the bag collection bin 150 and the feeding bin 110 are integrated into one unit, that is, the bag collection bin 150 and the feeding bin 110 share a single bin. The automatic unpacking equipment 100 may also include a bag collection device 9. The bag collection device 9 is located inside the bag collection bin 150. The bag collection device 9 is used to collect the ton bags 1a after the unloading operation has been completed. In the embodiments of this application, the bag breaking device 5 breaks the ton bags 1a, the material is unloaded from the ton bags 1a, and then the hook device 2 moves the ton bags 1a after the unloading operation has been completed to the bag collection device 9, whereby the bag collection device 9 recycles the ton bags 1a, which helps to reduce costs.

[0038] In some embodiments, the automatic unpacking equipment 100 may further include a dust removal device 47. The dust removal device 47 is disposed on the outer wall of the cabinet 1, thereby facilitating the assembly, maintenance, and cleaning of the dust removal device 47. The dust removal device 47 is connected to at least one of the feeding hopper 110, the bag collecting hopper 150, and the bag breaking hopper 130, so that the dust removal device 47 can absorb dust from at least one of these three hoppers. In this embodiment, the dust removal device 47 is connected to the feeding hopper 110 and can absorb dust detached from the top, sides, and bottom of the ton bag 1a. The dust removal device 47 is connected to the bag collecting hopper 150 and can absorb dust generated by compressing the ton bag 1a, reducing dust emission within the bag collecting hopper 150. The dust removal device 47 is connected to the bag breaking hopper 130 and can absorb dust generated by unloading the ton bag 1a, reducing dust emission within the bag breaking hopper 130.

[0039] It should be noted that, Figure 1 The purpose is merely to illustrate the arrangement of cabinet 1 and hook device 2, and is not to make specific limitations on the connection position, connection relationship and specific structure of each component. Figure 1 The structure of the automatic package unpacking device 100 illustrated in this application embodiment is merely a schematic representation and does not constitute a specific limitation on the automatic package unpacking device 100. In other embodiments of this application, the automatic package unpacking device 100 may include... Figure 1 The automatic unpacking device 100 may include, but is not limited to, identification devices, gas storage devices, and air jet devices, or may contain more or fewer components, or combinations of certain components, or different components. For example, in this embodiment, the identification device is located on the outside of the cabinet 1. The identification device is used to identify the position of the ton bag 1a, so that the lifting lug 12a of the ton bag 1a is aligned with the hook device 2, thereby improving the success rate of the hook device 2 in hooking the lifting lug 12a. The gas storage device is used to spray compressed gas into different functional areas of the cabinet 1 through the air jet device. In this embodiment, the gas storage device and the air jet device cooperate to spray compressed gas into different functional areas of the cabinet 1, which can play a role in dust removal and decontamination. Exemplarily, the compressed gas can be air. The gas storage device can also be connected to the air shower device 45 to spray air into the feed hopper 110 through the air shower device 45.

[0040] It should be noted that the ton bag 1a is a large-capacity, high-load-bearing freight bag used for packaging and transportation, typically for transporting solid goods such as granular, powdery, and lumpy substances. The ton bag 1a is used to load materials, including but not limited to battery materials, food materials, pharmaceutical materials, fertilizer materials, and building materials; the materials loaded in the ton bag 1a are not limited herein. For example, in this embodiment, the ton bag 1a is used to load battery materials. Battery materials include, but are not limited to, positive electrode materials, negative electrode materials, conductive agents, or dispersants; or, various materials are mixed to form a battery mixture.

[0041] Please refer to the following: Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of the structure of a ton bag 1a provided in an embodiment of this application. The ton bag 1a includes a bag body 11a and lifting lugs 12a. In this embodiment, the lifting lugs 12a can be provided on the outer side wall of the bag body 11a. Of course, in some embodiments, the lifting lugs 12a can also be provided at the top of the four corners of the bag body 11a or other positions. The number of lifting lugs 12a can be set to one or more. Exemplarily, in this embodiment, two lifting lugs 12a are provided on the outer side wall of the bag body 11a. The two lifting lugs 12a are symmetrically arranged with respect to the central axis of the ton bag 1a, thereby improving the uniformity of force distribution after the ton bag 1a is hooked by the hooking device 2.

[0042] Please refer to the following: Figure 1 and Figure 3 , Figure 3 yes Figure 1 The diagram shows the structure of the hook device 2 in the automatic unpacking device 100. The hook device 2 includes a mounting base 210, a translation drive 220, and two hook assemblies 230. The translation drive 220 and the two hook assemblies 230 are mounted on the mounting base 210. The translation drive 220 drives the two hook assemblies 230 to move closer to or further away from each other in the width direction Y of the hook assemblies 230. This facilitates the two hook assemblies 230 to hook the two lifting lugs 12a of the ton bag 1a respectively, improving the success rate of the hook device 2 in hooking the ton bag 1a and preventing damage to the ton bag 1a by the hook device 2.

[0043] In some embodiments, the hook device 2 further includes a sealing cover 250. A translation drive 220 is disposed inside the sealing cover 250. Thus, the sealing cover 250 can seal the translation drive 220 disposed on the mounting base 210. On the one hand, dust generated during the ton bag 1a's unpacking process cannot enter the movement hinge of the translation drive 220, enhancing the movement reliability and connection stability of the translation drive 220 relative to the mounting base 210, avoiding wear problems caused by material dust entering the moving parts of the mechanical structure, and extending its service life. On the other hand, it prevents metal powder and debris generated by the movement wear between the translation drive 220 and the mounting base 210 from entering the material, avoiding material contamination and meeting the requirements of product quality and environmental protection.

[0044] Please refer to the following: Figure 3 , Figure 4 and Figure 5 , Figure 4 yes Figure 3 A schematic diagram of the hook assembly 230 of the hook device 2 after removing part of its structure. Figure 5 yes Figure 3 A partial structural diagram of the hook assembly 230 of the hook-hanging device 2 is shown below. The hook assembly 230 includes a frame 21, a hook 23, an elastic element 235, and a detection element 236. The frame 21 is provided with a mounting hole 2102. The hook 23 passes through the mounting hole 2102 and is movably disposed relative to the frame 21 along the height direction Z of the hook assembly 230. One end of the hook 23 protruding from the mounting hole 2102 forms a bent hook portion 2311. The bent hook portion 2311 is used to hook the lifting lug 12a of the ton bag 1a. The elastic element 235 is connected between the other end of the hook 23 protruding from the mounting hole 2102 and the frame 21. The detection element 236 is mounted on the frame 21 and is located on the side of the hook 23 away from the bent hook portion 2311. When the hook weight of the hook 23 is greater than a preset value, the hook 23 causes the elastic element 235 to deform elastically and separate from the detection element 236. When the weight hooked by hook 23 is less than or equal to a preset value, elastic element 235 causes hook 23 to abut against detection element 236. Detection element 236 is used to detect the pressure exerted by hook 23 on detection element 236.

[0045] In this embodiment, the hook 23 is inserted into the mounting hole 2102 and is movably positioned relative to the frame 21 along the height direction Z of the hook assembly 230. When the hook weight of the hook 23 is greater than a preset value, the hook 23 causes the elastic element 235 to deform elastically and separate from the detection element 236. When the hook weight of the hook 23 is less than or equal to the preset value, the elastic element 235 causes the hook 23 to abut against the detection element 236. The detection element 236 is used to detect the pressure exerted by the hook 23 on the detection element 236. On the one hand, when the hook weight of the hook 23 is greater than the preset value, separating the hook 23 from the detection element 236 can prevent the hook 23 from pressing against the detection element 236. If the pressure of the 6th element exceeds the range of the detection element 236, to avoid damage to the detection element 236, when the hook weight of the hook 23 is less than or equal to the preset value, the elastic element 235 drives the hook 23 to abut against the detection element 236. Since the elastic element 235 is connected between the other end of the hook 23 through the mounting hole and the frame 21, and the detection element 236 is located on the side of the hook 23 away from the hook portion 2311, the elastic force provided by the elastic element 235 can partially offset the weight hooked on the hook 23, so that the pressure of the hook 23 on the detection element 236 is within the range of the detection element 236. Therefore, a high-precision detection element 236 can be selected. The pressure exerted by the elastic element 235 on the hook 23 and applied to the detection element 236 can accurately measure the weight hooked on the hook 23, thereby enabling precise measurement of the weight of residual material in the unloaded ton bag 1a. On the other hand, when the hook assembly 230 hooks a full ton bag 1a, if the hook 2311 fails to hook the lifting lug 12a of the ton bag 1a, the elastic element 235 drives the hook 23 to abut against the detection element 236. When the hook 2311 successfully hooks the lifting lug 12a of the ton bag 1a, the weight of the ton bag 1a causes the hook 23 to elastically deform and separate from the detection element 236, thus allowing the detection element 236 to measure the weight of the material remaining in the ton bag 1a. The measurement can determine whether the hook 2311 of the hook 23 has successfully hooked the lifting lug of the ton bag 1a, realizing automatic detection of whether the hook assembly 230 has successfully hooked the bag. On the other hand, after the hook assembly 230 has successfully hooked the bag, when the ton bag 1a is unloaded, the detection component 236 can detect the hook weight of the hook 23 to determine whether the ton bag 1a has been unloaded. Thus, the automatic unpacking equipment 100 can accurately weigh the ton bag 1a, automatically detect whether the bag has been successfully hooked, and automatically detect whether the ton bag 1a has been unloaded. This improves the automation level of the automatic unpacking equipment 100, reduces manual intervention, and improves the working efficiency and safety of the automatic unpacking equipment 100.

[0046] The elastic force applied by the elastic element 235 to the hook 23 is in the opposite direction to the pulling force applied by the ton bag 1a to the hook 23, so as to partially offset the pulling force of the ton bag 1a by the elastic force of the elastic element 235. The pressure of the hook 23 on the detection element 236 is the difference between the elastic force of the elastic element 235 and the pulling force of the ton bag 1a. The detection element 236 indirectly measures the weight of the ton bag 1a by detecting the magnitude of the pressure of the hook 23. The greater the pressure of the hook 23 on the detection element 236, the smaller the weight hooked on the hook 23, and the less material remains in the ton bag 1a. The smaller the pressure of the hook 23 on the detection element 236, the greater the weight hooked on the hook 23, and the more material remains in the ton bag 1a. When the detection element 236 does not detect pressure, the ton bag 1a is not completely unloaded. The preset value corresponds to the magnitude of the elastic force exerted by the elastic element 235 on the hook 23 when the hook 23 and the detection element 236 are in critical contact. In other words, the preset value corresponds to the degree of deformation of the elastic element 235 when the hook 23 and the detection element 236 are in critical contact. The elastic element 235 can be configured as a spring, elastic rope, torsion spring, etc.

[0047] It is understood that the weight of the residual material in different ton bags 1a will vary when unloading is completed, but the weight of the residual material in different ton bags 1a will remain within a certain range. In this embodiment, the preset value is greater than or equal to the sum of the maximum possible weight of the residual material in the ton bag 1a and the weight of the ton bag 1a itself. The maximum value of the measurement range of the detection element 236 is greater than or equal to the sum of the weight of the ton bag 1a itself and the maximum weight of the residual material. In some embodiments, the preset value is greater than or equal to the sum of the average weight of the residual material in the ton bag 1a and the weight of the ton bag 1a itself. The maximum value of the measurement range of the detection element 236 is greater than or equal to the sum of the weight of the ton bag 1a itself and the average weight of the residual material. In some embodiments, the preset value can be the sum of the weight of the ton bag 1a itself and the maximum weight (or average weight) of the residual material plus a certain value, so as to achieve accurate measurement of the sum of the weight of the ton bag 1a itself and the weight of the remaining material before the ton bag 1a is unloaded.

[0048] In this embodiment, when the ton bag 1a is full, the sum of the weight of the ton bag 1a and the material is typically greater than or equal to 400 kg. After unloading, the sum of the weight of the ton bag 1a itself and the weight of the remaining material is typically less than or equal to 3 kg. Compared to traditional automatic unpacking equipment where the detection element is fixedly connected to the hook, this embodiment decouples the detection element 236 from the hook 23. The detection element 236 detects the pressure applied by the hook 23 to the detection element 236, indirectly measuring the sum of the weight of the ton bag 1a itself and the weight of the remaining material. This significantly reduces the required measurement range of the detection element 236, allowing for the selection of a high-precision, small-range detection element 236, thereby achieving accurate measurement of the sum of the weight of the ton bag 1a itself and the weight of the remaining material. The weighing accuracy and range of the detection element 236 can be specifically set according to actual needs, and are not specifically limited in this application. For example, the weighing accuracy of the detection element 236 can be less than or equal to 10 g.

[0049] In some embodiments, the detection element 236 includes a detection section 2361 and an adjustment section 2362. The detection section 2361 is mounted on the frame 21. The adjustment section 2362 is connected to the detection section 2361. One end of the detection section 2361 is fixedly connected to the frame 21, and the other end of the detection section 2361 is a free end. The adjustment section 2362 is connected to the free end of the detection section 2361. The adjustment section 2362 is used to separate from the hook 23 when the hook weight of the hook 23 is greater than a preset value, and to abut against the hook 23 when the hook weight of the hook 23 is less than or equal to the preset value.

[0050] The protrusion length of the adjustment section 2362 relative to the detection section 2361 toward the hook 23 is adjustable. On the one hand, the magnitude of the elastic force of the elastic element 235 is positively correlated with the degree of deformation of the elastic element 235. By adjusting the protrusion length of the adjustment section 2362, the degree of deformation of the elastic element 235 when the adjustment section 2362 and the hook 23 are in critical contact can be adjusted, thereby adjusting the magnitude of the preset value. On the other hand, when the detection section 2361, the adjustment section 2362, the hook 23 and the frame 21 are assembled, assembly errors are inevitable, which will cause errors between the distance between the adjustment section 2362 and the hook 23 and the set assembly distance. By adjusting the protrusion length of the adjustment section 2362, assembly errors can be eliminated, thereby improving the measurement accuracy of the detection section 2361 and reducing measurement errors. Compared with eliminating installation errors by reassembling, this method can reduce assembly difficulty, improve assembly efficiency, and reduce the manufacturing cost of the automatic unpacking equipment 100.

[0051] In some embodiments, the adjustment part 2362 is arranged in an arc shape on the side near the hook 23 to reduce the contact area between the adjustment part 2362 and the hook 23 and improve the sensing accuracy of the adjustment part 2362 on the pressure of the hook 23.

[0052] In some embodiments, the detection unit 2361 detects the pressure on the hook 23 by detecting the magnitude of strain. When the hook 23 abuts against the adjustment unit 2362, the detection unit 2361 generates strain. The detection unit 2361 can also detect the pressure on the hook 23 by detecting other physical quantities, which are not specifically limited in this application. For example, the detection unit 2361 can also detect the pressure on the hook 23 by detecting photoelectric signals, capacitance signals, electromagnetic signals, etc.

[0053] The hook 23 includes a hook 231, a connector 232, and an abutment 233. The connector 232 is movably inserted into the mounting hole 2102. The hook 231 is fixedly connected to one end of the connector 232 that extends out of the mounting hole 2102. The end of the hook 231 away from the connector 232 forms a hook portion 2311. In some embodiments, the hook 231 and the connector 232 are independently arranged and fixed together by means of screwing, snap-fitting, welding, etc. In some embodiments, the hook 231 and the connector 232 can be integrally formed.

[0054] The abutment 233 is located at one end of the connector 232 through the mounting hole 2102 and is fixed relative to the connector 232. The elastic element 235 connects the abutment 233 and the frame 21. When the weight hooked by the hook portion 2311 is greater than a preset value, the hook 231 causes the connector 232, along with the abutment 233, to move relative to the frame 21, and the abutment 233 causes the elastic element 235 to undergo elastic deformation. When the weight hooked by the hook portion 2311 is less than or equal to the preset value, the elastic element 235 causes the abutment 233, along with the connector 232 and the hook 231, to move relative to the frame 21.

[0055] In some embodiments, the abutment 233 and the connector 232 are fixedly connected. The abutment 233 and the connector 232 can be fixed together by means of screwing, snapping, welding, bonding, etc., or the abutment 233 and the connector 232 can be integrally formed.

[0056] In some embodiments, the connector 232 abuts against the side of the abutment 233 opposite to the hook 231. The hook 23 may further include an abutment portion 2321, which is fixedly connected to the connector 232 and abuts against the side of the abutment 233 opposite to the hook 231. The abutment portion 2321 and the connector 232 can be independently configured and fixed together by means of screwing, snap-fitting, welding, or bonding; alternatively, the abutment portion 2321 and the connector 232 can be integrally formed. Exemplarily, the abutment portion 2321 and the connector 232 are independent of each other, and the abutment portion 2321 can be configured as a nut, with the abutment portion 2321 threadedly connected to the connector 232.

[0057] When the hook weight of hook 23 is less than or equal to a preset value, the detection element 236 abuts against the connector 232 and / or the abutment element 233. The detection element 236 may selectively abut against the connector 232 and / or the abutment element 233 as needed for assembly, thereby improving the layout rationality of the components in the hook assembly 230. In some embodiments, when the hook weight of hook 23 is less than or equal to a preset value, the detection element 236 abuts against the connector 232. In some embodiments, when the hook weight of hook 23 is less than or equal to a preset value, the detection element 236 abuts against the abutment element 233. In some embodiments, when the hook weight of hook 23 is less than or equal to a preset value, the detection element 236 abuts against both the connector 232 and the abutment element 233.

[0058] In some embodiments, the hook assembly 230 further includes a guide member 234. The guide member 234 is fixedly connected to the frame 21. The abutment member 233 is provided with a guide through hole 2333. The guide member 234 passes through the guide through hole 2333. The extending direction of the guide member 234 is parallel to the height direction Z of the hook assembly 230. The guide member 234 is used to guide the movement of the abutment member 233, so that the abutment member 233 moves along the height direction Z of the hook assembly 230. Multiple guide members 234 can be provided, and the multiple guide members 234 are arranged side by side in parallel. Multiple guide members 234 can improve the stability of the movement of the abutment member 233 and avoid problems such as jerking or jamming caused by unbalanced force when the abutment member 233 moves along the guide member 234.

[0059] The elastic element 235 is sleeved on the guide element 234 to guide the elastic element 235 when it undergoes elastic deformation, reduce the influence of external disturbances on the elastic deformation of the elastic element 235, and improve the linearity of the elastic deformation of the elastic element 235, thereby improving the accuracy of the pressure of the hook 23 detected by the detection element 236.

[0060] The abutment member 233 includes a base 2331 and an extension 2332. The extension 2332 is connected to the side of the base 2331 facing the frame 21. The base 2331 and the extension 2332 can be integrally formed or can be independently formed. For example, two extensions 2332 are provided, and the two extensions 2332 are connected to opposite ends of the base 2331. The base 2331 is fixed relative to the connector 232. An accommodating space 2330 is formed between the extension 2332 and the base 2331. The elastic member 235 is located within the accommodating space 2330 and elastically abuts against the base 2331 and the frame 21. Thus, through the protective effect of the extension 2332 and the base 2331, the entry of external impurities into the accommodating space 2330 can be reduced or avoided, preventing impurities from damaging the elastic member 235 and improving the service life and reliability of the elastic member 235.

[0061] The frame 21 includes a first crossbeam 2121, a second crossbeam 2122, and two side beams 211. The first and second crossbeams 2121 and 2122 are respectively connected between the two side beams 211. The first and second crossbeams 2121 and 2122 are spaced apart along the height direction Z of the hook assembly 230. The first, second, and two side beams 2121 are detachably connected or integrally formed. A guide 234 is fixedly connected to the first and / or second crossbeams 2121 and 2122. A detection element 236 is mounted on the second crossbeam 2122. A hook 23 is movably connected to the first crossbeam 2121. A mounting hole 2102 is provided on the first crossbeam 2121. The detection part 2361 of the detection element 236 is fixedly connected to the second crossbeam 2122.

[0062] In this embodiment, for example, the elastic element 235 elastically abuts against the first crossbeam 2121 and the hook 23. Specifically, the elastic element 235 elastically abuts against the first crossbeam 2121 and the base 2331. The guide element 234 can be fixedly connected to the first crossbeam 2121. The extension 2332 can be connected to the side of the base 2331 facing the first crossbeam 2121. When the hook weight of the hook 23 exceeds a preset value, the hook 231, through the connector 232, drives the base 2331 to move closer to the first crossbeam 2121. The base 2331 compresses the elastic element 235, causing it to deform, and the connector 232 separates from the detection element 236. When the hook weight of hook 23 is less than or equal to the preset value, elastic element 235 pushes base 2331 to move away from first crossbeam 2121 under the action of elastic force, and base 2331 drives connector 232 to abut against detection element 236.

[0063] In some embodiments, the elastic member 235 is elastically connected between the second crossbeam 2122 and the hook 23. One end of the elastic member 235 is fixedly connected to the second crossbeam 2122, and the other end is fixedly connected to the abutment member 233 and / or the connector 232. The guide member 234 may be fixedly connected to the second crossbeam 2122. The extension 2332 may be connected to the side of the base 2331 facing the second crossbeam 2122. When the hook weight of the hook 23 exceeds a preset value, the hook member 231, through the connector 232, drives the abutment member 233 to move towards the first crossbeam 2121. The abutment member 233 and / or the connector 232 stretch the elastic member 235, causing it to deform, and the connector 232 separates from the detection member 236. When the hook weight of hook 23 is less than or equal to the preset value, elastic element 235 pulls abutment 233 and / or connector 232 to move under the action of elastic force, so that abutment 233 moves away from the first crossbeam 2121 and connector 232 abuts against detection element 236.

[0064] In some embodiments, multiple elastic elements 235 may be provided. Each of the multiple elastic elements 235 elastically abuts against the first crossbeam 2121 and the hook 23; or, each of the multiple elastic elements 235 elastically connects to the second crossbeam 2122 and the hook 23; or, a portion of the multiple elastic elements 235 elastically abuts against the first crossbeam 2121 and the hook 23, while another portion of the multiple elastic elements 235 elastically connects to the second crossbeam 2122 and the hook 23. The number of elastic elements 235 can be specifically set according to actual needs and is not specifically limited in this application. For example, the number of elastic elements 235 can be 2, 3, 4, etc.

[0065] In some embodiments, the hook assembly 230 further includes a bag detection element 237. The bag detection element 237 is mounted on the frame 21 and is used to detect whether the hook 23 has hooked the lifting lug 12a. Exemplarily, the bag detection element 237 can be configured as a micro switch. The body of the micro switch is fixedly connected to the side of the abutment 233. When the hook 23 moves relative to the frame 21, the abutment 233 causes the micro switch to move closer to or away from the first crossbeam 2121, and causes the trigger end of the micro switch to abut or separate from the first crossbeam 2121, thereby triggering or resetting the micro switch. When the trigger end of the micro switch abuts against the first crossbeam 2121, the micro switch is in a triggered state, indicating that the hook 23 has successfully hooked the lifting lug 12a of the ton bag 1a. When the trigger end of the micro switch separates from the first crossbeam 2121, the micro switch is in a reset state, indicating that the surface hook 23 has not hooked the lifting lug 12a of the ton bag 1a or the ton bag 1a has been unloaded. The bag-hanging detection element 237 can also be configured as other types of detection elements, which are not specifically limited in this application. For example, the bag-hanging detection element 237 can also be configured as a photoelectric switch, pressure sensor, etc.

[0066] Please refer to the following: Figure 4 and Figure 6 , Figure 6 This is a schematic diagram of the structure of the tapping assembly 27 provided in an embodiment of this application. In some embodiments, the hook device 2 further includes the tapping assembly 27. The tapping assembly 27 includes a tapping drive member 271, a transmission member 272, and a tapping rod 273. The tapping drive member 271 is mounted on the frame 21. The tapping rod 273 includes a tapping part 2731 and a connecting part 2732. The tapping part 2731 is rotatably connected to the frame 21. The connecting part 2732 is fixedly connected to the tapping part 2731. One end of the transmission member 272 is rotatably connected to the tapping drive member 271, and the other end of the transmission member 272 is rotatably connected to the connecting part 2732. The striking drive component 271 drives one end of the transmission component 272 to move linearly, and causes the other end of the transmission component 272 to drive the connecting part 2732 and the striking part 2731 to rotate relative to the frame 21. This causes the striking part 2731 to strike the ton bag 1a, increasing the falling speed of the material in the ton bag 1a, reducing residual material, and thus improving the emptying of the ton bag 1a and reducing material waste. In addition, the striking assembly 27 is mounted on the frame 21, which can improve the integration of the hook assembly 230 and improve space utilization. Compared with the traditional method of driving the striking rod to rotate through a swing cylinder, in this embodiment, the moving end of the striking drive component 271 moves linearly. By driving one end of the transmission component 272 to move linearly through the striking drive component 271, the structural size of the striking drive component 271 can be reduced, the motion inertia of the striking drive component 271 can be reduced, the impact force can be reduced, and the service life, stability, and reliability can be improved.

[0067] The hook-and-hanging device 2 also includes a striking cover 274. The striking cover 274 is connected to the frame 21 and encloses a sealed cavity. The striking drive component 271, the transmission component 272, and the connecting part 2732 are located inside the sealed cavity to prevent external dust from entering the striking drive component 271, the transmission component 272, the connecting part 2732, and their connections, thereby improving the service life and reliability of the striking assembly 27 and preventing metal powder and debris generated during the operation of the striking assembly 27 from entering the material, thus avoiding material contamination and meeting the requirements of product quality and environmental protection. The striking part 2731 is located outside the sealed cavity.

[0068] The frame 21 also includes a support plate 217. The support plate 217 is C-shaped. Both ends of the support plate 217 are bent relative to the center. The two ends of the support plate 217 are connected between the bottoms of two side beams 211. The center of the support plate 217 is flat and perpendicular to the height direction Z of the automatic unpacking device 100. A striking assembly 27 is installed in the center of the support plate 217. In some embodiments, the striking assembly 27 also includes a connecting pin, and the support plate 217 of the frame 21 has a pin hole through which the connecting pin passes. A striking cover 274 and the support plate 217 enclose a closed cavity. A striking part 2731 is fixedly connected to the end of the connecting pin located outside the closed cavity, and the striking part 2731 is rotatably connected to the frame 21 via the connecting pin. A connecting part 2732 is fixedly connected to the end of the connecting pin located inside the closed cavity, and the connecting part 2732 is fixedly connected to the striking part 2731 via the connecting pin. The slapping drive 271 drives the connecting part 2732 to rotate around the central axis of the connecting pin through the transmission part 272, and the connecting part 2732 drives the slapping part 2731 to rotate around the central axis of the connecting pin through the connecting pin.

[0069] In this embodiment, two striking rods 273 and two transmission components 272 are respectively provided. One end of each transmission component 272 is rotatably connected to the striking drive component 271, and the other end of each transmission component 272 is connected to the connecting part 2732 of the corresponding striking rod 273. In this way, the striking assembly 27 can drive two striking rods 273 to simultaneously strike the ton bag 1a through one striking drive component 271, which can increase the striking force on the ton bag 1a, improve the striking effect, simplify the structure of the striking assembly 27, and reduce production costs.

[0070] In some embodiments, the hook assembly 230 further includes a limiting member 24 and a limiting drive member 25. The limiting member 24 is rotatably mounted on the frame 21. The limiting drive member 25 is drively connected to the limiting member 24 and is used to drive the limiting member 24 to rotate, thereby locking the lifting lug 12a between the limiting member 24 and the hook 23; or, to pull the lifting lug 12a off the hook 23. Thus, on the one hand, by using hook 23 to hook the lifting lug 12a of the ton bag 1a, the existing automatic unpacking equipment avoids the problem of damage to the woven bag caused by puncturing the ton bag 1a to hook it, and may even cause the woven debris to contaminate the material, thus improving the quality of the material. On the other hand, the automatic anti-detachment and automatic detachment functions of the lifting lug 12a of the ton bag 1a are realized based on the rotation of the limiting component 24, which prevents the lifting lug 12a from accidentally slipping off the hook 23, improving safety. Moreover, the hook 23 does not need to be equipped with an additional drive structure and transmission structure, thereby improving the integration of mechanical parts, reducing the number and weight of parts, reducing assembly difficulty, and making the structure simple and compact, occupying little space and low cost. Furthermore, no manual intervention is required for unpacking, which improves the working efficiency and safety of the automatic unpacking equipment 100.

[0071] Understandably, after the hook 23 catches the lifting lug 12a of the ton bag 1a, the limiting drive 25 drives the limiting member 24 to rotate in the first direction, so that the lifting lug 12a is locked and maintained between the hook 23 and the limiting member 24. Specifically, the limiting member 24 and the hook 23 enclose a limiting space that restricts the lifting lug 12a, thereby preventing the lifting lug 12a from detaching. After the ton bag 1a is unloaded, the limiting drive 25 drives the limiting member 24 to rotate in the second direction, so that the limiting member 24 pulls the lifting lug 12a away from the hook 23, thereby realizing the detachment of the ton bag 1a and facilitating the subsequent ton bag 1a recovery operation. The first direction and the second direction are opposite.

[0072] In this embodiment, the limiting member 24 includes a rotating shaft 241 and a limiting rod 242. The rotating shaft 241 is rotatably mounted on the frame 21 and is connected to the limiting drive member 25. The limiting rod 242 is fixedly connected to the rotating shaft 241. The limiting rod 242 is positioned close to the hook 23. In the projection plane perpendicular to the central axis of the rotating shaft 241, the free end of the hook 23 is within the swing range of the limiting rod 242. Thus, on the one hand, the rotating shaft 241 is driven to rotate by the drive member to drive the limiting rod 242 to swing, thereby reducing the space occupied by the limiting member 24 on the frame 21 and improving the overall compactness of the hook assembly 230; on the other hand, in the projection plane perpendicular to the central axis of the rotating shaft 241, the free end of the hook 23 is within the swing range of the limiting rod 242, thereby improving the success rate of the limiting rod 242 in locking and releasing the lifting lug 12a. Of course, in some embodiments, the rotating shaft 241 can be omitted, that is, the limiting member 24 includes the limiting rod 242, and the limiting drive member 25 is directly used to drive the limiting rod 242 to rotate.

[0073] The limiting rod 242 is configured as either an arc-shaped rod or a straight rod. Therefore, on the one hand, under the same force, an arc-shaped rod deforms more easily than a straight rod, thus reducing the friction between the limiting rod 242 and the ton bag 1a and the frame 21 when the limiting member 24 rotates, preventing the limiting rod 242 from scraping against the ton bag 1a or the frame 21 and generating debris. On the other hand, a straight rod is easier to manufacture, and when the ton bag 1a is in the locked state, because a straight rod is less prone to deformation than an arc-shaped rod, the lifting lug 12a of the ton bag 1a can be more securely locked between the limiting member 24 and the hook 23. Exemplarily, in this embodiment, the limiting rod 242 is configured as an arc-shaped rod.

[0074] The hook 231 is provided with a clearance groove 2301. The limiting rod 242 is rotatably inserted into the clearance groove 2301. The hook 231 forms hooks on both sides of the clearance groove 2301. When the limiting rod 242 rotates, the two hooks can provide a limiting and guiding effect for the swing of the limiting rod 242, thereby improving the success rate of locking and disengaging the lifting lug 12a by the limiting rod 242.

[0075] At least two hooks 23 and at least two limiting rods 242 are provided. At least two limiting rods 242 are spaced apart on the rotating shaft 241 and correspond one-to-one with each hook 23. Therefore, on the one hand, by providing multiple hooks 23, the weight of the ton bag 1a can be distributed, reducing the pressure on each hook 23, thus extending its service life and reducing the risk of breakage. Furthermore, multiple hooks 23 provide multiple support points, improving the stability of the ton bag 1a and the accuracy of subsequent puncture. On the other hand, each hook 23 cooperates with a corresponding limiting rod 242 to achieve automatic locking and automatic unhooking of the lifting lugs 12a of the ton bag 1a, improving the working efficiency and safety of the automatic unpacking equipment 100.

[0076] Of course, in some embodiments, the number of limiting rods 242 may be greater than the number of hooks 23. Multiple limiting rods 242 are spaced apart on the rotating shaft 241. For example, one hook 23 may correspond to two or three limiting rods 242, thereby increasing the locking force and peeling force of the limiting member 24 on the lifting lug 12a. It should be noted that the number of hooks 23 and limiting rods 242 can be set according to factors such as the load-bearing capacity of the hook 23 and the size of the ton bag 1a; this application embodiment does not impose specific limitations.

[0077] Please refer to the following: Figure 4 and Figure 7 , Figure 7 yes Figure 3 A cross-sectional view of the hook assembly 230 of the hook device 2. In some embodiments, the hook assembly 230 further includes a position sensor 26, which is mounted on the frame 21 and is used to generate a sensing signal when the ton bag 1a is detected to have reached the position of the hook 23. The position sensor 26 and the hook 23 are arranged at intervals along the length direction X of the hook assembly 230. Thus, when the ton bag 1a is detected to have reached the hook position, it indicates that the hook 23 is in contact with the ton bag 1a, thereby improving the success rate of the hook 23 in hooking the lifting lug 12a of the ton bag 1a and improving the safety of the automatic unpacking equipment 100. The position sensor 26 can be, but is not limited to, a photoelectric encoder, a magnetic encoder, a laser rangefinder, an ultrasonic sensor, etc.

[0078] In this embodiment, a mounting bracket 215 is provided on the frame 21, and the positioning sensor 26 is mounted on the mounting bracket 215. The mounting bracket 215 is detachably connected to the frame 21. In some embodiments, the mounting bracket 215 is pivotally connected to the frame 21, so that when the ton bag 1a presses against the positioning sensor 26, the mounting bracket 215 rotates relative to the frame 21, thereby reducing the risk of the ton bag 1a being crushed by the positioning sensor 26 during the hooking process of the ton bag 1a, and extending the service life of the positioning sensor 26. The mounting bracket 215 can be configured as a triangular bracket, thereby improving the structural integrity and stability of the mounting bracket 215, reducing weight, and saving costs. Of course, in some embodiments, the mounting bracket 215 can also be fixedly connected to the frame 21, and the mounting component can also be configured in other shapes, such as L-shaped, square, etc.

[0079] In some embodiments, the hook assembly 230 further includes a pushing structure 265. The pushing structure 265 includes a pushing drive 2651 and a push rod 2652. The pushing drive 2651 is mounted on the frame 21. One end of the push rod 2652 is throttle-connected to the push rod 2652, and the other end of the push rod 2652 abuts against the mounting bracket 215. The pushing drive 2651 drives the push rod 2652 to push the mounting bracket 215, so that the positioning sensor 26 moves closer to or further away from the ton bag 1a. Thus, the positioning sensor 26 can be flexibly mounted on the frame 21, improving the detection accuracy of the positioning sensor 26. In some embodiments, a roller 2653 is provided at the end of the push rod 2652 facing away from the pushing drive 2651, thereby reducing the friction between the push rod 2652 and the mounting bracket 215 and improving the pushing effect.

[0080] Please see Figure 8 , Figure 8 This is a schematic diagram of the hook assembly provided in an embodiment of this application. In some embodiments, the frame 21 further includes a protective cover 216. The protective cover 216 is fixedly connected to the frame 21. The protective cover and the frame 21 enclose a mounting cavity, and the hook 23 and the limiting member 24 are disposed within the mounting cavity. Thus, the protective cover 216 can prevent materials or other impurity particles from entering the mechanical parts within the protective cover 216 and affecting operation, and can also prevent debris generated within the mechanical parts within the protective cover 216 from entering the material and affecting the quality of the material.
