Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to an unloading device. Background Technology

[0002] In the production of seamless copper tubes for air conditioning and communication cables, horizontal rewinding is the final process before annealing. After the copper tubes are slit and wound into coils, the coils need to be separated from the drum for unloading. This separation and unloading process requires unloading equipment. Current unloading equipment uses hydraulic cylinders to control the lifting of the worktable. However, this design results in poor stability of the worktable, making the product prone to scratches during unloading due to the hydraulic cylinder's downward pressure. Furthermore, it hinders the maintenance and repair of the unloading equipment. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose an unloading device with a simple structural design, high stability, easy inspection and maintenance, and low failure rate.

[0005] The unloading device of this utility model includes: an unloading trolley, which includes a base, a linkage assembly, and a worktable. The worktable is located on the upper side of the base, and the linkage assembly is installed between the base and the worktable; a driving device, which includes a driver and a drive rod. The driver is connected to the drive rod, and the drive rod is connected to the linkage assembly. The driver and the unloading trolley are arranged along a first direction. The driver can push the unloading trolley to move along the first direction through the drive rod, and can control the movement of the linkage assembly to adjust the lifting height of the worktable.

[0006] According to the unloading device of this utility model, since the driver can push the unloading cart to move in a first direction through the drive rod and can control the linkage assembly to adjust the lifting height of the worktable, on the one hand, the number of drive sources of the unloading device can be reduced, so that the driver can control both the translation and lifting height of the unloading cart, thereby simplifying the structure of the unloading device, facilitating its inspection and maintenance, and reducing the failure rate of the unloading device. On the other hand, the linkage assembly can control the lifting height of the worktable, which can improve the stability of the worktable when carrying materials compared to the "hydraulic cylinder-driven worktable lifting" solution. Therefore, the unloading device of this utility model has a simple structural design, high stability, is easy to inspect and maintain, and has a low failure rate.

[0007] In some embodiments, the linkage assembly includes a first arm and a second arm, which are arranged crosswise. The lower end of the first arm is pivotally connected to the base, and the upper end of the first arm is pivotally connected to the worktable. The lower end of the second arm is slidable relative to the base along the first direction, and the upper end of the second arm is slidable relative to the worktable along the first direction.

[0008] In some embodiments, the unloading vehicle further includes a locking assembly connected to the second arm, and the drive rod is connected to the second arm via the locking assembly. The locking assembly is movable between a locked state and a released state. In the locked state, the locking assembly is fixed relative to the base so that the drive rod pushes the unloading vehicle to move in the first direction. In the released state, the locking assembly can slide relative to the base in the first direction so that the drive rod pushes the worktable to rise and fall.

[0009] In some embodiments, the locking assembly includes an adapter rod extending along a second direction, wherein the first direction, the second direction, and the vertical direction of the unloading vehicle are orthogonal to each other, the drive rod is fixedly connected to the adapter rod, the adapter rod is slidably connected to the base along the first direction, and the lower end of the second arm is pivotally connected to the adapter rod.

[0010] In some embodiments, the locking assembly includes an adapter rod and a latching rod, the adapter rod being fixedly connected to the drive rod, the latching rod being pivotally connected to the adapter rod, and the base having a locking port. In the locked state, the latching rod engages within the locking port, and in the released state, the latching rod disengages from the locking port.

[0011] In some embodiments, the base is provided with a return stop block. When the unloading vehicle moves toward the initial position in the direction close to the driver, the adapter rod abuts against the return stop block, and the locking rod engages in the locking port.

[0012] In some embodiments, the latching rod has a latching portion that engages within the locking port in the locked state. The unloading vehicle further includes a triggering component that engages at least partially within the locking port. When the unloading vehicle moves to a target position in a direction away from the driver, the triggering component can be triggered to push the latching portion out of the locking port.

[0013] In some embodiments, the triggering assembly includes a limiting block, a trigger rod, and an elastic reset member. The limiting block is located at the target position. The trigger rod and the elastic reset member are both located on the lower side of the base. The locking rod is located on the upper side of the base. The trigger rod extends along the first direction, with its first end extending outside the base. The second end of the trigger rod has a trigger portion that engages within the locking port. The elastic reset member is in contact with the trigger portion and presses it in the direction toward the limiting block. When the unloading vehicle moves to the target position in the direction away from the driver, the first end of the trigger rod contacts the limiting block and pushes the trigger rod to move in the direction away from the limiting block, so that the trigger portion disengages the locking portion from the locking port. When the unloading vehicle moves from the target position toward the driver, the trigger rod can separate from the limiting block. At this time, the elastic reset member presses the trigger portion in the direction toward the limiting block, so that the trigger portion returns to its pre-trigger position. In some embodiments, the trigger portion has a first inclined surface, the latching portion has a second inclined surface, and in the locked state, the first inclined surface and the second inclined surface cooperate, and both the first inclined surface and the second inclined surface extend upward at an angle close to the limiting block.

[0014] In some embodiments, the unloading vehicle further includes a traveling wheel disposed on the lower side of the base, and the unloading device further includes a track extending along the first direction, wherein the traveling wheel rolls in cooperation with the track along the first direction.

[0015] In some embodiments, there are at least two sets of connecting rod assemblies, which are arranged at intervals on the base along a second direction, wherein the first direction, the second direction, and the vertical direction of the unloading vehicle are orthogonal to each other.

[0016] In some embodiments, the driver includes a motor assembly, the drive rod is a lead screw, and the motor assembly is connected to the lead screw to drive the lead screw to move along the first direction.

[0017] In some embodiments, the unloading device further includes a contact sensor disposed on the worktable for sensing material on the worktable, the contact sensor being electrically connected to the driver. Attached Figure Description

[0027] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The following is a reference appendix. Figures 1 to 8 This invention describes an unloading device according to an embodiment of the present invention.

[0029] like Figures 1 to 4As shown, the unloading device of this utility model embodiment includes: an unloading cart 1 and a driving device 2. The unloading cart 1 includes a base 11, a connecting rod assembly 13, and a worktable 12. The worktable 12 is located on the upper side of the base 11. The connecting rod assembly 13 is installed between the base 11 and the worktable 12. The driving device 2 includes a driver 21 and a driving rod 22. The driver 21 is connected to the driving rod 22, and the driving rod 22 is connected to the connecting rod assembly 13. The driver 21 and the unloading cart 1 are connected along a first direction (e.g., ...). Figure 1 Arranged in the front-back direction, the driver 21 can push the unloading car 1 to move in the first direction through the drive rod 22, and can control the action of the linkage assembly 13 to adjust the lifting height of the worktable 12.

[0030] Understandably, the driver 21 remains stationary with respect to the ground, and the driver 21 can drive the drive rod 22 to move in the first direction, so as to correspond to the unloading vehicle 1 moving in the first direction (front and back direction).

[0031] According to the unloading device of the present invention, since the driver 21 can push the unloading cart 1 to move in the first direction through the drive rod 22 and can control the action of the linkage assembly 13 to adjust the lifting height of the worktable 12, on the one hand, the number of drive sources of the unloading device can be reduced, so that the driver 21 can control both the translation of the unloading cart 1 and the lifting height of the unloading cart 1, thereby simplifying the structure of the unloading device, facilitating the inspection and maintenance of the unloading device, and reducing the failure rate of the unloading device. On the other hand, the linkage assembly 13 can control the lifting height of the worktable 12, which can improve the stability of the worktable 12 when carrying materials compared with the "hydraulic cylinder driving the lifting of the worktable 12" scheme. Therefore, the unloading device of the present invention has a simple structural design, high stability, is easy to inspect and maintain, and has a low failure rate.

[0032] The unloading device of this utility model can be directly installed on the ground without digging a pit, thus eliminating the problem of copper buckles or other objects falling into a narrow pit, facilitating cleaning and equipment maintenance. In addition, since the unloading device can be directly installed on the ground, it is not limited by the width of the pit, meaning that the size of the workbench 12 can be designed according to the size of the material (copper coil), which helps to improve the applicability of the unloading device.

[0033] like Figures 1 to 3As shown, when the unloading trolley 1 is in the waiting position, the worktable 12 is in a lowered state. When material needs to be loaded, the unloading trolley 1 moves forward to move the worktable 12 below the material. Then, the linkage assembly 13 actuates to raise the worktable 12 to the corresponding height. After the drum and copper coil are separated, the unloading trolley 1 begins its return motion (moving backward). The driver 21 drives the drive rod 22 to move in the opposite direction, causing the worktable 12 of the unloading trolley 1 to descend. Once the worktable 12 has descended to its final position, the unloading trolley 1 moves backward as a whole until it returns to the waiting position. At this point, the return motion of the unloading trolley 1 is complete, and one cycle of the unloading trolley 1 is finished.

[0034] Optionally, such as Figures 1 to 4 As shown, the linkage assembly 13 includes a first arm 131 and a second arm 132, which are arranged crosswise. The lower end of the first arm 131 is pivotally connected to the base 11, and the upper end of the first arm 131 is pivotally connected to the worktable 12. The lower end of the second arm 132 is slidable relative to the base 11 along a first direction, and the upper end of the second arm 132 is slidable relative to the worktable 12 along the first direction. It can be understood that the crosswise arrangement of the first arm 131 and the second arm 132, generally forming a scissor-like structure, allows the first arm 131 and the second arm 132 to move in tandem along the first direction relative to the base 11 when the drive rod 22 pushes the second arm 132 to slide relative to the base 11. This enables the worktable 12 to rise or fall. This improves the stability of the worktable 12 when carrying materials, and the structural design is simple, facilitating subsequent maintenance and reducing the failure rate.

[0035] The linkage assembly 13 is at least two sets, and the two sets of linkage assemblies 13 are along the second direction (e.g., Figure 1 The workbench 12 is arranged at intervals in the left and right directions on the base 11, with the first direction, the second direction, and the vertical direction of the unloading vehicle 1 being orthogonal to each other. This can further improve the load-bearing capacity of the workbench 12 and avoid the problem of tilting when the workbench 12 is carrying materials.

[0036] Optionally, such as Figure 4 and Figure 5 As shown, the unloading vehicle 1 also includes a locking assembly 14, which is connected to the second arm 132. The drive rod 22 is connected to the second arm 132 via the locking assembly 14. The locking assembly 14 is movable between a locked state and a released state. In the locked state, the locking assembly 14 is fixed relative to the base 11 so that the drive rod 22 can push the unloading vehicle 1 to move in a first direction. In the released state, the locking assembly 14 can slide relative to the base 11 in the first direction so that the drive rod 22 can push the worktable 12 to rise and fall.

[0037] It is understandable that when the locking component 14 is in the locked state, during the forward and backward movement of the unloading vehicle 1 driven by the drive rod 22, the connecting rod assembly 13 will not move, meaning the height of the worktable 12 of the unloading vehicle 1 can remain relatively fixed. When the locking component 14 is in the released state, the drive rod 22 can push the connecting rod assembly 13 to move through the locking component 14. At this time, the first arm 131 and the second arm 132 can move synchronously to raise or lower the worktable 12. Thus, the unloading device of this embodiment can decouple the forward and backward movement of the unloading vehicle 1 from the lifting movement of the worktable 12, so as to realize the free switching between the forward and backward movement and the up and down movement of the unloading vehicle 1. It also has a simple structure, is easy to control, and has a low failure rate.

[0038] like Figure 1 , Figure 6 and Figure 7 As shown, the locking assembly 14 includes a transition rod 141 extending along a second direction. The first direction, the second direction, and the vertical direction of the unloading vehicle 1 are all orthogonal to each other. The drive rod 22 is fixedly connected to the transition rod 141. The transition rod 141 is slidably connected to the base 11 along the first direction. The lower end of the second arm 132 is pivotally connected to the transition rod 141. It can be understood that the transition rod 141 connects the two linkage assemblies 13 together so that the left and right linkage assemblies 13 can move synchronously, which helps to improve the stability of the worktable 12 of the unloading vehicle 1 when it is raised and lowered.

[0039] For example, such as Figure 6 and Figure 7 As shown, the end of the adapter rod 141 has a roller 1411, and the base 11 is provided with a guide rail 112. The guide rail 112 extends along the first direction, and the roller 1411 rolls and engages within the guide rail 112 to improve the smoothness of the adapter rod 141 when it moves along the first direction.

[0040] Optionally, such as Figure 6 and Figure 7 As shown, the locking assembly 14 includes an adapter rod 141 and a locking rod 142. The adapter rod 141 is fixedly connected to the drive rod 22, and the locking rod 142 is pivotally connected to the adapter rod 141. Figure 5 and Figure 8 As shown, the base 11 is provided with a locking port 111. In the locked state, the locking rod 142 engages within the locking port 111, and in the released state, the locking rod 142 disengages from the locking port 111. It can be understood that when the locking rod 142 engages within the locking port 111, the locking assembly 14 can be relatively fixed to the base 11. When the drive rod 22 provides a pushing or pulling force in the first direction to the unloading vehicle 1, the linkage assembly 13 will not drive the worktable 12 to rise or fall. That is, in the locked state, when the drive device 2 drives the unloading vehicle 1 to move in the forward and backward direction, the worktable 12 can remain stationary.

[0041] When the locking rod 142 disengages from the locking port 111, the locking assembly 14 is released from the base 11. When the drive rod 22 provides a pushing or pulling force in the first direction to the unloading vehicle 1, the drive rod 22 can push the locking assembly 14 to move in the first direction, and the scissor-type linkage assembly 13 will actuate to drive the worktable 12 to rise and fall. By setting the locking assembly 14 to the above-described structure, the unloading device of this utility model simplifies the implementation of the locking assembly 14 and makes it easy to manufacture.

[0042] Optionally, such as Figure 1 As shown, a return stop 16 is provided on the base 11. When the unloading vehicle 1 moves towards the initial position near the drive 21, the adapter rod 141 abuts against the return stop 16, and the locking rod 142 engages within the locking port 111. It can be understood that the return stop 16 can limit the movement of the adapter rod 141 to improve the accuracy of the unloading vehicle 1's movement. Figure 3 As shown, the return stop 16 is located on the side of the base 11 near the driver 21. When the adapter rod 141 moves backward to the limit position, the adapter rod 141 can abut against the return stop 16.

[0043] Optionally, such as Figure 5 and Figure 8 As shown, the latching rod 142 has a latching portion 1421. In the locked state, the latching portion 1421 engages within the locking port 111. The unloading carriage 1 also includes a triggering assembly 15, at least a portion of which engages within the locking port 111. When the unloading carriage 1 moves to the target position in a direction away from the drive 21, the triggering assembly 15 can be triggered to push the latching portion 1421 out of the locking port 111. It can be understood that when the unloading carriage 1 moves to the material picking position (i.e., the target position), the triggering assembly 15 can be triggered to disengage the latching portion 1421 from the locking port 111. Thus, when the drive rod 22 continues to move forward, since the locking assembly 14 is unlocked, when the drive rod 22 provides a forward thrust to the unloading carriage 1, the drive rod 22 can push the locking assembly 14 forward. At this time, the scissor-type linkage assembly 13 is extended to drive the worktable 12 to rise.

[0044] like Figure 4 and Figure 5As shown, the trigger assembly 15 includes a limiting block 151, a trigger rod 152, and an elastic reset member 153. The limiting block 151 is located at the target position. The trigger rod 152 and the elastic reset member 153 are both located on the lower side of the base 11. The locking rod 142 is located on the upper side of the base 11. The trigger rod 152 extends along a first direction. The first end of the trigger rod 152 extends out of the base 11. The second end of the trigger rod 152 has a trigger portion 1521. The trigger portion 1521 is fitted into the locking port 111. The elastic reset member 153 is connected to the trigger portion 1521 and presses the trigger portion 1521 in the direction toward the limiting block 151. When the unloading vehicle 1 moves to the target position in the direction away from the driver 21, the first end of the trigger rod 152 contacts the limit block 151 and pushes the trigger rod 152 to move in the direction away from the limit block 151, so that the trigger part 1521 disengages the locking part 1421 from the locking port 111.

[0045] Understandably, when the unloading trolley 1 moves to the target position, the trigger rod 152 can touch the limit block 151. Under the stopping action of the limit block 151 and the inertial force of the unloading trolley 1 moving forward, the trigger rod 152 can move backward relative to the base 11 to push the locking part 1421 out of the locking port 111 and unlock the locking component 14. Thus, when the drive rod 22 provides a forward thrust to the unloading trolley 1, the drive rod 22 can push the locking component 14 forward. At this time, the scissor-type linkage assembly 13 is opened to drive the worktable 12 to rise.

[0046] In addition, when the unloading vehicle 1 moves backward from the target position, the trigger rod 152 can separate from the limit block 151. At this time, the elastic reset member 153 presses the trigger part 1521 in the direction of the limit block 151 so that the trigger part 1521 is reset to the position before triggering, thereby preparing for the next reciprocating motion of the unloading vehicle 1.

[0047] For example, such as Figure 5 and Figure 8 As shown, the trigger part 1521 has a first inclined surface 15211, and the latching part 1421 has a second inclined surface 14211. In the locked state, the first inclined surface 15211 and the second inclined surface 14211 cooperate, and both the first inclined surface 15211 and the second inclined surface 14211 extend upwards at an angle close to the limiting block 151. Under the guidance of the first inclined surface 15211 and the second inclined surface 14211, the trigger part 1521 can more smoothly push the latching part 1421 upwards to the locking port 111, so that the unlocking process of the locking assembly is smoother, and the structural design is simple and easy to manufacture.

[0048] like Figure 4As shown, the unloading vehicle 1 also includes a traveling wheel 17, which is located on the lower side of the base 11. The unloading device also includes a track 3, which extends along a first direction. The traveling wheel 17 rolls in cooperation with the track 3 along the first direction. This can improve the smoothness of the forward and backward movement of the unloading vehicle 1. In addition, the cooperation between the traveling wheel 17 and the track 3 can ensure that the unloading vehicle 1 can travel in a straight line.

[0049] Optionally, the actuator 21 includes a motor assembly, and the drive rod 22 is a lead screw. The motor assembly is connected to the lead screw to drive the lead screw to move in a first direction. Compared with the solution of "actuator 21 is hydraulically driven", the transmission method of "motor + lead screw" has a certain rigidity, which can effectively solve the impact force generated by the downward pressing of the copper coil, and thus solve the quality problem of damage to the outer layer of the product.

[0050] Optionally, such as Figure 3 and Figure 4 As shown, the unloading equipment also includes a contact sensor 18, which is located on the workbench 12 to sense the material on the workbench 12. The contact sensor 18 is electrically connected to the driver 21 to improve the intelligence level of the unloading equipment during operation.

[0051] The working principle of the unloading device in this embodiment of the utility model is as follows: (1) The drive rod 22 of the unloading vehicle 1 is fixedly connected to the adapter rod 141, and the locking rod 142 is rotatably mounted on the adapter rod 141 through a pin. When the unloading vehicle 1 is in the waiting position, the locking rod 142 is in a horizontal state, and at this time the locking part 1421 is locked into the locking port 111 of the base 11. When the drive device 2 pushes the unloading vehicle 1 forward, the drive rod 22 pushes the adapter rod 141 to move forward, and the adapter rod 141 pushes the locking rod 142 to move. Since the locking rod 142 is relatively fixed to the base 11, it pushes the entire unloading vehicle 1 to move forward. The traveling wheel 17 on the lower side of the unloading vehicle 1 cooperates with the track 3. The traveling wheel 17 has a directional anti-detachment function to ensure that the unloading vehicle 1 can move in a straight line along the first direction.

[0052] (2) When the unloading vehicle 1 is pushed to the target position, the trigger rod 152 collides with the limit block 151 and pushes the trigger rod 152 to move. Under the interaction of the first inclined surface 15211 of the trigger part 1521 and the second inclined surface 14211 of the locking part 1421, the locking part 1421 of the locking rod 142 can be lifted upward, so that the locking part 1421 is no longer locked in the locking port 111 of the base 11.

[0053] (3) Drive rod 22 continues to advance under the action of driver 21, and adapter rod 141 continues to move forward. At this time, base 11 no longer advances. Adapter rod 141 drives linkage assembly 13 to advance along guide rail 112 so that linkage assembly 13 can rise according to the scissor lift principle until the worktable 12 is raised to a suitable position. Contact sensor 18 is triggered by material and sends a stop signal to driver 21, thereby completing the advance action of unloading car 1.

[0054] (4) When the unloading vehicle 1 finishes picking up the material, the unloading vehicle 1 starts the return action, the drive rod 22 pulls back in the opposite direction, and the transfer rod 141 moves back along the guide rail 112 to drive the linkage assembly 13 to move. When the worktable 12 is lowered to the position, the transfer rod 141 contacts the return stop 16.

[0055] (5) Drive rod 22 continues to pull back in the opposite direction. Under the action of return stop 16, transfer rod 141 pulls the unloading car 1 to move backward as a whole, so that the lowering action of unloading car 1 is switched to backward movement. Under the action of elastic reset member 153, trigger rod 152 is reset and no longer pushes up locking rod 142. At this time, locking rod 142 will return to its original position, and locking part 1421 will fall back into locking port 111 of base 11, automatically resuming the initialization of the next pushing action. Unloading car 1 moves backward until it reaches the waiting position and stops, completing the unloading operation.

[0056] The unloading device of this utility model has at least the following technical effects: (1) The unloading equipment does not need to be dug when it is installed. That is, the unloading equipment can be installed on the ground. Therefore, there is no problem of copper buckles or other objects falling into the narrow pit, which facilitates cleaning and equipment maintenance.

[0057] (2) The unloading equipment uses only one motor as the power source and uses a mechanical structure to realize the movement and up-down switching of the unloading vehicle 1. The structure is simple, the control is convenient, and the failure rate is low.

[0058] (3) The screw drive of the unloading equipment 2 is rigid, which can effectively solve the impact force generated by the downward pressure of the copper coil, and thus solve the quality problem of damage to the outer layer of the product.

[0059] (4) The advantage of the unloading equipment being installed on the ground makes the unloading equipment more adaptable. The structure of the unloading vehicle 1 can be designed according to the different product roll widths and is not limited by the foundation pit.

[0061] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
