Description

Technical Field

[0001] This utility model relates to the field of wire reel technology, specifically to a wire reel for an automated three-dimensional warehouse with over-limit detection. Background Technology

[0002] With social development and improved living standards, the market demand for spinning is increasing, and its production process is receiving more and more attention. Transportation is a very important part of the production process, but the existing production and spinning methods are mostly manual transportation, which cannot effectively classify products and make it difficult to find the required products conveniently and quickly. In addition, products are often disordered during transportation. Therefore, people use spinning wheels to move bobbins in automated warehouses and transport them to transfer vehicles.

[0003] Due to their unique shape (such as long length, easy bending, or tangling), wire-cart-type goods are prone to exceeding preset loading boundaries (such as fork extension range or loading platform size) during automated storage and retrieval due to factors such as stacker crane platform positioning deviations, goods tilting, or external vibrations. This can lead to goods colliding with the racks, falling, or even equipment damage. Existing automated warehouses cannot dynamically identify the over-limit status of wire-carts, which can easily cause accidents.

[0004] Therefore, it is necessary to invent a wire car for automated storage and retrieval systems with over-limit detection to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a wire trolley for an automated storage and retrieval system with over-limit detection. By cooperating with the mounting plate and the over-limit detection mechanism, the weight of the wire trolley itself can be detected, thereby solving the problem that existing automated storage and retrieval systems cannot dynamically identify the over-limit status of the wire trolley, which can easily lead to accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire trolley for an automated three-dimensional warehouse with over-limit detection, comprising a mounting plate, an over-limit detection mechanism disposed below the mounting plate, the over-limit detection mechanism comprising a threaded rod rotatably connected to the inside of the mounting plate, a lifting plate being threadedly connected to the outer wall of the threaded rod and slidably connected to the inside of the mounting plate, a sliding groove being formed on the surface of the lifting plate and an L-shaped support plate being slidably connected within the sliding groove, a reflective material being coated on the back side of the L-shaped support plate, two sets of support screws being fixedly connected to the front end of the L-shaped support plate, an over-limit laser transceiver being fixedly connected to the bottom surface of the lifting plate, a warning laser transceiver being fixedly connected above the over-limit laser transceiver, the warning laser transceiver being fixedly connected to the lifting plate, and buzzers being disposed on both sides of the warning laser transceiver. By sliding the L-shaped support plate, the bottom end of the warning laser transceiver reflects the signals from the over-limit laser transceiver and the warning laser transceiver, thereby determining whether an over-limit has occurred, and then triggering an alarm via the buzzers.

[0007] Preferably, the L-shaped support plate is internally slidably connected to a sliding rod, which is fixedly connected to the sliding groove of the lifting plate. The outer wall of the sliding rod is fitted with a butterfly spring, and the top of the butterfly spring is fixedly connected to an elastic pad. The L-shaped support plate is elastically supported by the cooperation of the sliding rod and the butterfly spring.

[0008] Preferably, the inner sidewall of the mounting plate is slidably connected to two sets of connecting frames, the connecting frames are fixedly connected to both ends of the lifting plate, and the outer sidewall of the connecting frames is fixedly connected to a drive box, so that synchronous lifting is achieved through the connection between the connecting frames and the lifting plate.

[0009] Preferably, the output end of the drive box is fixedly connected to a toggle block, which is slidably connected to the surface of the connecting frame. The drive box drives the toggle block to push the bobbin on the surface of the lead screw to move along the lead screw.

[0010] Preferably, a servo motor is fixedly connected to the top of the mounting plate, and the output end of the servo motor is fixedly connected to the threaded rod. Activating the servo motor enables the lifting plate and the connecting frame to be raised and lowered.

[0011] Preferably, a movable carriage is fixedly connected to the bottom end of the mounting plate, and a main vehicle body is fixedly connected to the front side of the mounting plate, so that the mounting plate and other parts can move through the main vehicle body.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] By combining the mounting plate with the overload detection mechanism, the displacement changes of the L-shaped load-bearing plate are monitored in real time using the laser ranging principle, thereby identifying the weight changes during the loading process of the cable drum. The dual-probe design, which integrates an overload laser transceiver and a warning laser transceiver, can distinguish between critical overload (early warning) and actual overload (alarm), providing more accurate safety protection. The detection mechanism is integrated into the bottom of the lifting plate, requiring no additional installation space, which meets the stringent requirements of automated warehouses for equipment compactness.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1-5The diagram shows an automated storage and retrieval system (AS / RS) with over-limit detection, comprising a mounting plate 1. An over-limit detection mechanism 2 is disposed below the mounting plate 1. The over-limit detection mechanism 2 includes a threaded rod 201 rotatably connected to the interior of the mounting plate 1. A lifting plate 202 is threadedly connected to the outer wall of the threaded rod 201 and slidably connected to the interior of the mounting plate 1. A sliding groove is formed on the surface of the lifting plate 202, and an L-shaped support plate 203 is slidably connected within the sliding groove. The back side of the L-shaped support plate 203 is coated with a reflective material. Two sets of support rods 204 are fixedly connected to the front end of the L-shaped support plate 203. An over-limit laser transceiver 207 is fixedly connected to the bottom surface of the lifting plate 202. A warning laser transceiver 208 is fixedly connected above the over-limit laser transceiver 207 and is fixedly connected to the lifting plate 202. Buzzers 209 are installed on both sides of the body 208. By sliding the L-shaped support plate 203, the bottom end of the L-shaped support plate 203 reflects the signals of the over-limit laser transceiver 207 and the warning laser transceiver 208 to determine whether the limit is exceeded. Then, the buzzers 209 sound an alarm. A sliding rod 205 is slidably connected inside the L-shaped support plate 203 and is fixedly connected to the sliding groove of the lifting plate 202. A butterfly spring 206 is sleeved on the outer wall of the sliding rod 205 and an elastic pad is fixedly connected to the top of the butterfly spring 206. The L-shaped support plate 203 is elastically supported by the cooperation of the sliding rod 205 and the butterfly spring 206. Two sets of connecting frames 4 are slidably connected to the inner wall of the mounting plate 1. The connecting frames 4 are fixedly connected to both ends of the lifting plate 202. A drive box 5 is fixedly connected to the outer wall of the connecting frame 4. Synchronous lifting is achieved by connecting the connecting frame 4 and the lifting plate 202.

[0024] Refer to the instruction manual appendix Figure 1-5 A toggle block 6 is fixedly connected to the output end of the drive box 5. The toggle block 6 is slidably connected to the surface of the connecting frame 4. The drive box 5 drives the toggle block 6 to push the bobbin on the surface of the lead screw 204 to move along the lead screw 204. A servo motor 3 is fixedly connected to the top of the mounting plate 1. The output end of the servo motor 3 is fixedly connected to the threaded rod 201. Starting the servo motor 3 realizes the lifting of the lifting plate 202 and the connecting frame 4. A movable carriage 8 is fixedly connected to the bottom end of the mounting plate 1. A main body 7 is fixedly connected to the front side of the mounting plate 1. The main body 7 drives the movable carriage 8 to move along the connecting frame 4. Mounting plate 1 moves with other parts. Through the cooperation of mounting plate 1 and over-limit detection mechanism 2, the displacement change of L-shaped bearing plate 203 is monitored in real time by laser ranging principle, thereby identifying the weight change during the loading process of the cable. The dual-probe design of over-limit laser transceiver 207 and warning laser transceiver 208 can distinguish between critical overload warning and actual over-limit alarm, providing more accurate safety protection. The detection mechanism is integrated into the bottom of lifting plate 202, requiring no additional installation space, which meets the stringent requirements of the automated warehouse for equipment compactness.

[0025] The working principle of this practical application is as follows:

[0026] Refer to the instruction manual appendix Figure 1-5 After the bobbin is loaded onto the thread support rod 204, its weight is transferred to the L-shaped support plate 203, forcing the support plate to move down along the sliding rod 205 and compress the disc spring 206. The downward movement distance is inversely proportional to the load weight. The over-limit laser transceiver 207 vertically emits a laser to the reflective material on the back of the L-shaped support plate 203. The intensity of the received reflected signal increases as the downward movement distance of the support plate increases. When the reflected signal meets the preset threshold, it is determined to be an over-limit state, triggering the buzzer 209 alarm. When it is necessary to transfer the bobbin, the servo motor 3 drives the threaded rod 201 to adjust the height of the lifting plate 202 so that it is aligned with the transfer trolley. The drive box 5 pushes the bobbin through the toggle block 6, so that the bobbin is transferred from the thread support rod 204 to the transfer trolley, thereby completing the transfer.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
