Description

Technical Field

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

[0002] Chinese utility model patent publication number CN212952671U discloses a drive device for a screw conveyor, including a drive mechanism and a chain conveying mechanism disposed on the screw conveyor; the drive mechanism includes a drive source and a drive disk driven to rotate by the drive source, the drive disk is provided with at least one universal coupling for adjusting the torque of the screw conveyor, the drive disk is provided with toothed grooves around its perimeter, and the drive disk drives the chain conveying mechanism to transmit along the helical track on the screw conveyor.

[0003] The drive unit of this screw conveyor uses a chain conveying mechanism installed along the spiral track. The material is transported via the carrying section of the chain conveyor, thus achieving spiral conveying and reducing the space occupied in the factory. However, the drive unit of this screw conveyor relies on a chain arranged along the spiral track. In practical applications, the winding spiral track easily leads to chain jamming. When there are many track layers, the use of a spliced ​​chain conveyor mechanism results in a complex structure and high manufacturing, use, and maintenance costs. In addition, other existing screw conveyors also use segmented synchronous belt mechanisms or blade-type transmission mechanisms with a spiral arrangement along the track, which also suffer from complex structures and high manufacturing, use, and maintenance costs. Furthermore, the structure of this type of machine is generally suitable for contact conveying of materials placed on a transfer platform, and cannot meet the specific needs of this application.

[0004] There is an urgent need to develop a technical solution to address the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a spiral lifting device that uses an independently driven rotating mechanism for horizontal rotation and an independently driven lifting mechanism for lifting motion, which are coupled through electromechanical coupling. This makes control easier and helps reduce manufacturing, use, and maintenance costs. 。

[0006] To achieve the above objectives, this utility model provides the following technical solution;

[0007] A spiral lifting device includes a rotating mechanism and a lifting mechanism for synchronously driving a transfer structure to move spirally along a spiral track;

[0008] The rotating mechanism is driven by a lifting mechanism, and the lifting mechanism is driven by at least one feeding arm.

[0009] During operation, the rotating mechanism drives the lifting mechanism and the material-picking arm to rotate. During the rotation of the lifting mechanism, the material-picking arm is driven to move up and down, so that the material-picking arm pushes or pulls the transfer structure to move along the spiral track.

[0010] Furthermore, the rotating mechanism includes a central shaft rotatably installed in a spiral track, at least one rotating arm frame connected to the central shaft, and a first drive mechanism for driving the central shaft to rotate; the lifting mechanism is installed on the rotating arm frame; during operation, the first drive mechanism drives the central shaft to rotate with the rotating arm frame, and then the rotating arm frame drives the lifting mechanism and the material feeding arm to rotate.

[0011] Furthermore, the lifting mechanism includes a transmission belt or transmission chain mounted on the slewing arm and a second drive mechanism for driving the transmission belt or transmission chain. At least one of the material-picking arms is driven to connect with the transmission belt or transmission chain. During operation, the second drive mechanism drives the transmission belt or transmission chain to move, causing the material-picking arm to move up and down, thereby pushing the transfer structure to move along the path of the spiral track.

[0012] Furthermore, the plurality of feeding arms are spaced apart along the axial direction of the central rotating shaft; the distance between two feeding arms located in adjacent layers of the spiral track is equal to the pitch of the spiral track.

[0013] Furthermore, the plurality of lifting mechanisms are arranged circumferentially around the reference circle of the spiral track.

[0014] Furthermore, it also includes a frame, on which both the rotating mechanism and the helical track are mounted.

[0015] Furthermore, the frame is provided with multiple mounting brackets in the circumferential direction around the reference circle of the spiral track.

[0016] Furthermore, the spiral track includes a track connecting frame, and the spiral track is spirally installed with the frame using the track connecting frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This spiral lifting device decomposes the spiral motion into independent drives of rotation and lifting under the drive of the rotation mechanism and the lifting mechanism. The horizontal rotation motion and the lifting motion are coupled together through electromechanical coupling, replacing the existing complex mechanical linkage conveying and mechanical structure. This makes the structure of the invention relatively simple, easy to control, and the spatial phase of the feeding arm and the spiral track is precisely matched. The failure rate is low during use, reducing the cost of manufacturing, use and maintenance. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] refer to Figure 1-3 As shown, a spiral lifting device includes a rotating mechanism 41 and a lifting mechanism 42 for synchronously driving the transfer structure 3 to move spirally along the spiral track 2.

[0024] The rotating mechanism 41 is driven by the lifting mechanism 42, and the lifting mechanism 42 is driven by at least one feeding arm 43.

[0025] During operation, the rotating mechanism 41 drives the lifting mechanism 42 and the material-pulling arm 43 to rotate. During the rotation of the lifting mechanism 42, the material-pulling arm 43 is driven to move up and down, so that the material-pulling arm 43 pushes or pulls the transfer structure 3 to move along the spiral track 2.

[0026] Specifically, while the material-pulling arm 43 is driven by the rotating mechanism 41 to rotate horizontally and push or pull the transfer structure 3 to unfold horizontally along the spiral track 2, the material-pulling arm 43 itself continuously pushes or pulls the transfer structure 3 to move towards the leading spiral track 2 through the continuous rising or falling movement of the lifting mechanism 42.

[0027] This spiral lifting device, driven by the rotating mechanism 41 and the lifting mechanism 42, decomposes the spiral motion into independent drives of rotation and lifting. By electromechanically coupling the horizontal rotation of the independently driven rotating mechanism 41 with the lifting motion of the independently driven lifting mechanism 42, it replaces the complex mechanical linkage conveying and mechanical structure of existing spiral conveyors, which are set up in segments along the spiral track, such as chain conveying mechanism, synchronous belt mechanism, and blade type transmission mechanism. As a result, the structure of this invention is relatively simple, the control is easier, and the spatial phase of the feeding arm 43 and the spiral track 2 is precisely matched, resulting in a low failure rate during use and helping to reduce manufacturing, use and maintenance costs.

[0028] This invention can be used for spiral lifting and conveying of various materials, enabling the classification, sorting and conveying of materials, so as to accurately sort and convey products to different floors and realize automated transportation across floors.

[0029] When this utility model is used for conveying meat products such as pig carcasses, the meat products are loaded by the transfer structure 3 and then conveyed along the spiral track 2. The spiral is lifted by the combined drive of the rotating mechanism 41 and the lifting mechanism 42, so that it adopts a horizontal transport line method compared with the existing slaughtering equipment. It is not only compact in structure and occupies little space, but also facilitates the setting of several required slaughtering, sorting and sorting workstations at different heights of the spiral track 2, thereby facilitating the realization of automation and batch processing on an assembly line.

[0030] In this embodiment, the rotating mechanism 41 includes a central shaft 412 rotatably installed in the spiral track 2, at least one rotating arm frame 413 connected to the central shaft 412, and a first driving mechanism 411 for driving the central shaft 412 to rotate; the lifting mechanism 42 is installed on the rotating arm frame 413; during operation, the first driving mechanism 411 drives the central shaft 412 to rotate with the rotating arm frame 413, and then the rotating arm frame 413 drives the lifting mechanism 42 and the feeding arm 43 to rotate.

[0031] Specifically, multiple lifting mechanisms 42 are arranged around the reference circle of the spiral track 2 on the rotating frame 413. The rotation of the first drive mechanism 411 realizes the rotation of the rotating arm frame 413, ensuring that the lifting mechanisms 42 installed on the rotating arm frame 413 can rotate along the inner circle of the spiral track 2. Multiple sets of lifting mechanisms 42 can be installed on the multi-set rotating arm frame 413 as needed, thereby realizing the pushing of multiple transfer structures 3, increasing the loading capacity of the spiral track 2, and improving the lifting and transportation efficiency of meat products.

[0032] In this embodiment, the lifting mechanism 42 includes a transmission belt or transmission chain 422 mounted on the slewing arm frame 413 and a second driving mechanism 421 for driving the transmission belt or transmission chain 422. At least one of the material-picking arms 43 is driven to connect with the transmission belt or transmission chain 422. During operation, the second driving mechanism 421 drives the transmission belt or transmission chain 422 to move, causing the material-picking arm 43 to move up and down, thereby pushing the transfer structure 3 to move along the path of the spiral track 2.

[0033] Specifically, the second drive mechanism 421 drives the lifting pulley 422, which in turn drives the material-pulling arm 43 to rise and fall, so that the material-pulling arm 43 can adapt to the height changes of the transfer structure 3 when it moves in the spiral track 2, ensuring that the material-pulling arm 43 can always be in contact with and push the transfer structure 3; during the descent, the rotating mechanism 41 reverses, and in conjunction with the descent of the second drive mechanism 421, the material-pulling arm 43 can similarly pull or block the transfer structure 3 that is spirally descending along the spiral track 2, thereby limiting the descent speed and improving the safety of meat product transportation and loading; and multiple material-pulling arms 43 are axially spaced on the central rotating shaft 412; the distance between two material-pulling arms 43 located in adjacent layers of the spiral track 2 is equal to the pitch of the spiral track 2, ensuring that the displacement stroke of each material-pulling arm 43 is precisely matched with the spatial phase of the spiral track 2; multiple material-pulling arms 43 are set in the same lifting mechanism 42, and one material-pulling arm 43 can be set in different spiral layers of the spiral track 2 to achieve synchronous batch material conveying in each spiral layer of the spiral track 2.

[0034] In this embodiment, preferably, the first drive mechanism 411 and the second drive mechanism 421 include, but are not limited to, variable frequency motors, servo motors, hydraulic motors, stepper motors, etc. The speed can be controlled by the frequency, pulse, or hydraulic flow given by the frequency converter. At the same time, negative feedback is introduced through the encoder to perform PID speed regulation on the dual drive speed of the first drive mechanism 411 and the second drive mechanism 421, so as to ensure the spatiotemporal consistency of power transmission again. Furthermore, the torque of the drive motor can be used to monitor the jamming abnormality during operation, and the electromechanical coupling of the first drive mechanism 411 and the second drive mechanism 421 can replace the complex mechanics of the existing screw conveyor.

[0035] In this embodiment, the feeding arms 43 are spaced apart along the axial direction of the central rotating shaft 412; the distance between two feeding arms 43 located in adjacent layers of the spiral track 2 is equal to the pitch of the spiral track 2, ensuring that the displacement stroke of each feeding arm 43 is precisely matched with the spatial phase of the spiral track 2.

[0036] Multiple material feeding arms 43 are set in the same lifting mechanism 42. One material feeding arm 43 can be set in different spiral layers of the spiral track 2 to realize synchronous batch material conveying in each spiral layer of the spiral track 2.

[0037] In this embodiment, multiple lifting mechanisms 42 are arranged around the circumference of the reference circle of the spiral track 2. The number of lifting mechanisms 42 can be set as needed. Multiple lifting mechanisms 42 are set to realize batch material conveying at multiple positions in each spiral layer of the spiral track 2.

[0038] In this embodiment, a frame 1 is also included, and the rotating mechanism 41 and the spiral track 2 are both mounted on the frame 1. The frame 1 is provided with a plurality of mounting brackets 11 around the circumference of the reference circle of the spiral track 2. The plurality of mounting brackets 11 are vertically arranged on the outer periphery of the reference circle of the spiral track 2. The spiral track 2 is installed in a spiral upward manner by using mounting brackets 11, which reduces the installation difficulty of the spiral track 2 and improves the overall stability of the spiral track 2.

[0039] In this embodiment, the spiral track 2 includes a track connecting frame 21, and the spiral track 2 is spirally installed with the frame 1 using the track connecting frame 21. The track connecting frame 21 can be installed in any form, such as fixed, suspended, or sliding assembly, which facilitates the installation and debugging of the spiral track 2, improves the stability of the spiral structure, and ensures the safe and stable completion of the lifting operation.

[0040] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by the spirit of this utility model.
