Description

Technical Field

[0001] The present application relates to the technical field of lifting and loading equipment, and in particular to an automatic copper stack transfer device. Background Art

[0002] As an important industrial metal material, copper is often stored and transported in the form of stacks during smelting, processing and warehousing. After copper metal is smelted, when it is supplied to the downstream industry, copper plates can usually be packaged into copper stacks for transportation through steel belts, etc. This involves the transfer of copper stacks from conveyor lines and warehouses to loading vehicles.

[0003] Traditional loading operations mainly rely on electromagnetic lifting, mechanical clamping, bundling and other methods. As for electromagnetic technology, it is often used for the transportation of steel materials. Since copper materials are not magnetic, it is basically not applicable. In the mainstream technical solutions, it is difficult to automate the loading operations by mechanical loading. In order to ensure the safety and reliability of the operation, the operator needs to control the clamping and release of the copper stack. More complex copper stack packaging or fixing methods, such as wire rope or steel belt packaging, are too complicated and are rarely used in temporary loading and unloading operations. In general, there is currently a lack of lifting equipment that can be used for fully automatic operations in copper stack loading and unloading operations. Summary of the invention

[0004] In view of the fact that the current copper stack loading equipment generally has a low degree of automation and it is difficult to achieve the requirements of production line automation, the present application provides an automatic copper stack transfer equipment.

[0005] The present application provides a copper stack automatic transfer device, including a scissor support assembly and a locking assembly; The scissor brace assembly includes two groups of clamping arms that are rotatably arranged around the same rotation axis. The clamping arms generally have a relatively fixed clamping portion and a suspension portion. When the suspension portion moves upward around the rotation axis, the clamping portions of the two scissor brace assemblies are relatively close to each other. The locking assembly enables the clamp arm to alternately switch between a locked state and an unlocked state on the rotating axis: the clamp arm is unlocked when clamping and is locked when releasing.

[0006] Preferably, the clamping portion comprises a contact portion and a connecting portion, the contact portion contacts the surface of the target product to achieve a clamping function, and the connecting portion is used to connect the suspension portion and the contact portion.

[0007] Preferably, the distance between the connecting parts of the two clamping arms is smaller than the distance between the clamping parts, so that when the target product contacts the connecting part, the connecting part can be driven to rotate around the rotation axis to open the clamping part.

[0008] Preferably, the locking assembly has a guide sleeve and a support member fixed to the cross bracing assembly, and also has a locking pin movably disposed within the locking assembly. The locking pin can move axially along the guide sleeve and can rotate about an axis within the guide sleeve; the contact section at the lower end of the locking pin extends out of the guide sleeve to contact the target product. The locking pin has a locking section at the upper end, and a support section and a rotation driving section located between the locking section and the contact section; The rotation driving section drives the locking pin to rotate between a first preset position and a second preset position when the locking pin moves up and down; in the first preset position, the support member causes the locking pin to be at a high point, and the locking pin enters the locking groove of the clamping arm to lock the clamping arm; in the second preset position, the support member causes the locking pin to be at a low point, and the locking pin exits the locking groove of the clamping arm to enable the clamping arm to move.

[0009] Preferably, the support member has a through hole for the support section to pass through under the second preset position.

[0010] Preferably, the support member has a through hole for the support section to pass through under the second preset position.

[0011] Preferably, the rotation driving section includes a main rotation structure and a secondary rotation structure respectively located at both ends of the guide sleeve; both the main rotation structure and the secondary rotation structure are composed of mutually meshing tooth-shaped edges provided at the end of the guide sleeve and on the circumferential surface of the locking pin.

[0012] Preferably, during the upward stroke and the downward stroke of the locking pin, the main rotation structure and the secondary rotation structure respectively play a role alternatively; The main rotation structure realizes the rotation of the locking pin, so that the support section switches between a first preset position passing through the through hole and a second preset position not passing through the through hole.

[0013] Preferably, the secondary rotation structure is used to drive the through hole to rotate by a specific angle to prepare for the next rotation of the main rotation structure.

[0014] Preferably, the locking assembly includes an induction device and a locking assembly. The locking device is used to lock the state of the clamping arm on the rotating shaft, and the induction device is used to detect the copper stack.

[0015] Through the cooperation of the locking assembly and the cross bracing assembly provided in this application, the clamping and releasing of the lifting equipment are automatically controlled according to the specific situation of the copper stack, thereby realizing a completely automated material transfer and handling operation of the lifting equipment corresponding to the copper stack.

Detailed implementation manners

[0018] The technical solutions of the present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments. In this specification, the dimensions of the drawings do not represent the actual dimension ratios. The drawings are only used to reflect the relative positional relationship and connection relationship between components. Components with the same name or the same reference numeral represent similar or identical structures, and are for illustrative purposes only.

[0019] The present application provides a scissor lifting equipment. The lifting equipment 1 first includes an X-shaped bracing component 11 that performs the operations of clamping and transferring steel plates, and also includes a locking component 12. The X-shaped bracing component 11 includes two groups of clamping arms 111 that are rotatably arranged around the same rotating shaft 112. The clamping arms 111 generally have relatively fixed clamping parts 114 and suspension parts 115, and usually ensure that when the suspension parts 115 make upward movements around the rotating shaft 112, the clamping parts 114 of the two X-shaped bracing components 11 approach each other relatively. This enables the two relatively approaching suspension parts 115 to possibly clamp the copper stack W when the steel wire ropes are stressed and tighten the suspension parts 115.

[0020] Basically, the X-shaped bracing component 11 is an implementation of the prior art, which can achieve the basic goal of clamping the copper stack, but cannot achieve reliable process control. On the one hand, it is impossible to more precisely control the timing of clamping and releasing, resulting in unsmooth coordination of the overall equipment during the loading and unloading process, that is, the clamping and releasing of the copper stack and the transfer of the copper stack cannot be well matched, so that the connection process is not smooth and there may be potential safety hazards. For example, when the copper stack is not reliably clamped and the movement is triggered, it may cause the copper stack to become unstable or fall during the movement. On the other hand, such an X-shaped bracing component 11 must require manual operation by the operator because it cannot achieve reliable state confirmation and movement connection. Finally, it should be noted that during the manual operation process, not only should attention be paid to the timing of clamping and releasing of the X-shaped bracing component 11, but also it is necessary to ensure that the clamping arms 111 are in a suitable open state before clamping so that the copper stack W can enter between the two clamping arms 111.

[0021] The locking assembly 12 of the present application includes a sensing device 121 and a locking device 122. The locking device 122 is used to lock the state of the clamping arm 111 on the rotating shaft 112, that is, to prevent the clamping arm 111 from rotating around the rotating shaft 112. The sensing device 121 is used to detect the copper stack W.

[0022] The two cooperate to complete the following tasks. First, during the clamping process, when the sensing device 121 detects that the copper stack W is located at a preset position between the two clamping parts 114, the unlocking of the locking device 122 is triggered. The preset position can be defined in advance by adjusting the accuracy and state of the sensing device 121. Due to the above linkage between the sensing device 121 and the locking device 122 during clamping, once the copper stack W enters the preset position between the clamping parts 114, the locking of the locking device 122 on the scissors brace assembly 11 can be released. At this time, the lifting wire rope can control the clamping arm 111 to rotate around the rotating shaft 112 together, so as to achieve the purpose of clamping the copper stack W by the clamping parts 114.

[0023] Second, during the release process, when the sensing device 121 detects that the copper stack W is located at a preset position between the two clamping parts 114, the locking of the locking device 122 is triggered, so that the clamping arm 111 is locked after being opened around the rotating shaft 112 to a preset state, that is, the clamping arm 111 is maintained at a certain opening degree until it is unlocked during clamping.

[0024] The above operations during the clamping step and the release step objectively achieve such a closed loop. That is, the release step realizes the opening and holding of the clamping parts 114, that is, resets, so that the clamping parts 114 can be applied to the next clamping process without adjustment. Then, during the operation process, the expected clamping and transfer function is realized through the clamping operation.

[0025] The above settings of the two operations of clamping and releasing of the locking assembly 12 are necessary. The clamping operation solves the timing and reliability problems of the operation of clamping the copper stack W. The release operation is still necessary because usually, under the self-weight of the scissors brace assembly 11, if not locked, during the process of the wire rope hanging the scissors brace assembly 11 into the clamping position, the distance between the clamping parts 114 is relatively close, rather than in the required open state. This means that if the holding operation after release is not set, the clamping parts 114 cannot complete the initial state setting during clamping, that is, open at a suitable opening degree so that the copper stack W can enter between the clamping parts 114.

[0026] Figure 1It is an embodiment of the lifting device 1. The clamping portion 114 may have a contact portion 116 and a connecting portion 117, wherein the contact portion 116 contacts the surface of the copper stack W to achieve a clamping function, and the connecting portion 117 is used to connect the suspension portion 115 and the contact portion 116. The connecting portion 117 is not limited to the connecting function, and is also used to perform some auxiliary functions in certain circumstances. The connecting portion 117 particularly preferably provides an opening function of the auxiliary clamping portion 114. Specifically, in the process of releasing the copper stack W, the clamping portion 114 is required not only to lose the clamping of the copper stack W after the wire rope is unloaded, but also to be partially opened to achieve resetting and maintenance. The existence of 1 lies in that, after the wire rope is unloaded, the relative height between the scissors-strut assembly 11 and the copper stack W changes, so that the scissors-strut assembly 11 descends relative to the copper stack W, which makes the copper stack W contact the connecting part 117 and push the connecting part 117 to open around the rotating axis 112, thereby realizing the opening function of the clamping part 114. In some embodiments, this function is not necessarily achievable during the release process.

[0027] Specifically, the distance between the connecting parts 117 of the two clamping arms 111 is usually smaller than the distance between the clamping parts 114, so that when the copper stack W contacts the connecting parts 117, the connecting parts 117 can be driven to rotate around the rotating shaft 112 to open the clamping parts 114. Further, the connecting parts 117 can be expanded in a trumpet shape from top to bottom, such as the inclined transition shown in the figure. The purpose is to gradually open the clamping parts 114 as the copper stack W contacts.

[0028] The locking assembly 12 can be implemented by means of electronic devices or mechanical devices. When the electronic method is usually adopted, the sensing device 121 can be a sensor device that senses the presence of copper stacks, such as a photoelectric sensor, a pressure sensor, etc., and naturally, it is not limited to the above sensor types. The locking device 122 can generally be implemented by a device that implements mechanical locking or electromagnetic locking. The mechanical locking device can be a locking device based on a movable key or a pin arranged on the rotating shaft 112, or it can be a locking component arranged at the contact part of the two clamping arms 111. This locking component can be an insert type or an extrusion type, such as a friction self-locking wedge component.

[0029] An embodiment of the present application provides a locking assembly 12 for a mechanical device. In a specific mechanical locking assembly 12, the sensing device 121 and the locking device 122 can be understood as integrally arranged without strict distinction. In the illustrated locking assembly 12, there is a guide sleeve 123 fixed to the scissors brace assembly 11 and a support member 124. There is also a locking pin 126 movably arranged within the guide sleeve 123. The locking pin 126 can not only move axially along the guide sleeve 123 but also rotate around an axis within the guide sleeve 123. The sensing section 264 at the lower end of the locking pin 126 extends out of the guide sleeve 123 for contacting the copper stack W. Under the resistance of the copper stack W, the locking pin 126 can move upward. In the case of no contact, the locking pin 126 will fall to the possible lowest point. In this regard, the lower end of the locking pin 126 is equivalent to the aforementioned sensing device 121.

[0030] The locking pin 126 has a locking section 261 at the upper end, and a support section 262 and a rotation driving section 263 located between the locking section 261 and the sensing section 264. The support section 262 has a non-rotary cross-section. At the same time, there is a through hole 125 on the support member 124 for the support section 262 to pass through in a specific state. Briefly speaking, when the locking pin 126 has a specific phase angle relative to the guide sleeve 123, the cross-section of the support section 262 is completely within the space of the through hole 125, then the support section 262 can pass through the through hole 125, and thus the locking pin 126 can descend to the low point A. In other cases, since the support section 262 cannot pass through the through hole 125 after rotating a certain angle, the support section 262 supports above the support member 124, and at this time it is at the high point B. At the high point B, the locking section 261 enters the corresponding locking groove on the clamping arm 111 to prevent the rotation of the clamping arm 111. At the low point A, the locking section 261 exits the corresponding locking groove in the clamping arm 111, restoring the possibility of rotation between the clamping arms 111.

[0031] The switching between the low point and the high point depends on the rotational movement of the locking pin 126. In the present application, through the rotation driving section 263, the up-and-down movement of the locking pin 126 driven by the copper stack W or its own weight is synchronously converted into a rotational movement. It includes a main rotation structure 265 and a secondary rotation structure 266 respectively located at both ends of the guide sleeve 123. Both the main rotation structure 265 and the secondary rotation structure 266 are composed of tooth-shaped edges that can mesh with each other, which are arranged at the end of the guide sleeve 123 and on the circumferential surface of the locking pin 126. During the upward stroke and the downward stroke of the locking pin 126, the main rotation structure 265 and the secondary rotation structure 266 respectively play a role alternately. Among them, the main rotation structure 265 realizes the rotation of the locking pin 126, so that the support section 262 switches between the phase where it can pass through the through hole 125 and the phase where it cannot pass through the through hole 125. The secondary rotation structure 266 is used to drive the through hole 125 to rotate a specific angle to prepare for the next rotation of the main rotation structure 265.

[0032] In the illustrated example, the main rotating structure 265 is located at the lower end of the support member 124, and the secondary rotating structure 266 is located above the support member 124. Obviously, the main rotating structure 265 plays a role when rising, and the secondary rotating structure 266 plays a role when descending. The tooth-shaped structure of 2 is periodically arranged in four groups, that is, during one rising process, the locking pin 126 rotates 90 degrees. The support section 262 can be a non-rotating cross-section, such as an elliptical or other polygonal cross-section, or a technical solution of laterally arranging the intercepting pin 267 in the figure. The shape of the through hole 125 on the support member 124 is not particularly required, and only needs to satisfy that the support section 262 can pass through the through hole 125 at a preset first phase and cannot pass through the through hole 125 at a second preset position after rotation.

[0033] During the clamping process, the copper stack W jacks up the contact section 264, the locking pin 126 rotates to the second preset position, the support section 262 passes through the support member 124 and enters below the through hole 125 or the support member 124. The locking pin 126 is at the low point B, and the locking section 261 withdraws from the clamping arm 111. The clamping arm 111 can rotate, so that the copper stack W can be clamped during the process of lifting the scissors bracing assembly 11.

[0034] During the release process, as the scissors bracing assembly 11 descends, the copper stack W contacts the contact section 264 again and jacks up the contact section 264. Under the structure of the main rotating structure 265, the locking pin 126 will alternate between the high point A and the low point B. Therefore, after being jacked up again, the locking pin 126 will be at the high point A. That is to say, the locking pin 126 will enter the locking groove on the clamping arm 111 to prevent the rotation of the clamping arm 111, so that the clamping arm 111 is maintained at a certain opening until the next round of clamping starts. It should be noted that the main rotating structure 265 has four tooth-shaped structures evenly distributed in this embodiment. Uniform setting is not necessary, as long as two rotating positions with different phases are ensured. As for whether it is 90 degrees between the two rotating positions, we do not require it.

[0035] The above content is only a description of the preferred implementation manner of this application, and does not limit the scope of this application. Without departing from the design spirit of this application, various deformations and improvements made by those of ordinary skill in the art to the technical solution of this application should fall within the protection scope determined by the claims of this application.
