Description

Technical Field

[0001] This utility model relates to the field of elevator landing door panel processing technology, and specifically discloses an elevator landing door panel processing and conveying equipment with an anti-slip structure. Background Technology

[0002] Elevator landing door panels are a crucial component of the elevator system, and their manufacturing precision directly impacts the overall quality and safety of the elevator. On the door panel processing production line, multi-roller conveyors are typically used for inter-process transfer. Operators place the door panels on the conveyor rollers, and relying on the rotation of the rollers or a slight incline, the door panels move forward under the influence of gravity or friction until they reach the designated processing station.

[0003] However, in practical applications, the existing conveying method suffers from slippage and misalignment of the door panels due to their smooth surfaces and limited friction between the conveyor rollers and the panels. This is particularly problematic during equipment start-up and shutdown, speed changes, or when transporting thicker or wider door panels. This slippage leads to uncertain positions of the door panels on the conveyor line, preventing them from reaching subsequent processing stations on time and accurately, severely disrupting production rhythm and reducing efficiency. Secondly, existing equipment positioning methods often rely on manual observation and operation of blocking components (such as manual baffles or pins). Manual operation is not only inefficient but also prone to positioning errors due to human judgment, directly causing deviations in subsequent punching, folding, and other processing steps, resulting in batch quality defects, material waste, and increased production costs. Utility Model Content

[0004] This utility model proposes an elevator landing door panel processing and conveying equipment with an anti-slip structure. The anti-slip structure of the elevator landing door panel processing and conveying equipment can effectively solve the problem of door panel slippage during conveying, achieve accurate automatic positioning of door panels, adapt to different specifications of door panels, improve conveying efficiency, reduce labor and maintenance costs, extend equipment life, and indirectly ensure the processing quality of door panels.

[0005] This utility model is implemented as follows: an elevator landing door panel processing and conveying device with an anti-slip structure includes a multi-roller conveyor frame and multiple conveying rollers disposed inside the conveyor frame. A base plate is fixedly installed at the bottom of the conveyor frame, and an anti-slip mechanism is provided at the top of the conveyor frame. The anti-slip mechanism includes two symmetrically distributed support plates fixedly installed on the upper end face of the conveyor frame. Each support plate has a movable moving component on its upper end face. The moving component includes a first moving box with an open side and a wedge-shaped second moving box. The first and second moving boxes are connected, and their open sides face the conveying direction. The interior of the first moving box is rotatably connected to two symmetrically distributed first rotating wheels, and the interior of the second moving box is rotatably connected to a second rotating wheel. The two first rotating wheels and the second rotating wheel are triangularly distributed, and the outer walls of the two first rotating wheels and the second rotating wheel are jointly fitted with a friction belt for pressing and conveying the door panel.

[0006] The top of the support plate is provided with a drive mechanism that can drive the moving component to move.

[0007] The tail end of the conveyor frame is provided with a positioning mechanism, which includes a second electric push rod and a blocking rod that is driven to rise and fall by the second electric push rod, as well as a position detector for detecting whether the door panel has reached the preset work position.

[0008] As a preferred embodiment of the elevator landing door panel processing and conveying equipment with an anti-slip structure according to this utility model, the positioning mechanism includes a second electric push rod fixedly installed on the top of the base plate, a movable plate fixedly installed at the output end of the second electric push rod, and a plurality of front-and-back distributed blocking rods fixedly installed on the top of the movable plate.

[0009] As a preferred embodiment of the elevator landing door panel processing and conveying equipment with anti-slip structure of this utility model, both the front and rear ends of the moving plate are slidably connected to a U-shaped frame fixedly installed on the top of the base plate.

[0010] As a preferred embodiment of the elevator landing door panel processing and conveying equipment with an anti-slip structure according to this utility model, a first electric push rod is fixedly installed on the top of the support plate, and a pressure sensor is installed between the output end of the first electric push rod and the first moving box.

[0011] As a preferred embodiment of the elevator landing door panel processing and conveying equipment with anti-slip structure of this utility model, the top of the support plate is fixedly installed with two symmetrically distributed slide rails, and the bottom of the first and second movable boxes are provided with slide grooves that slide in connection with the slide rails.

[0012] As a preferred embodiment of the elevator landing door panel processing and conveying equipment with an anti-slip structure according to this utility model, the outer side wall of the friction belt is provided with anti-slip protrusions.

[0013] In a preferred embodiment of the elevator landing door panel processing and conveying equipment with an anti-slip structure according to this utility model, the position detector is fixedly installed on the top of the tail end of the conveyor frame, and a PLC controller is fixedly installed on the outer side wall of the conveyor frame. The position detector and the second electric push rod are both electrically connected to the controller.

[0014] The beneficial effects of this utility model are:

[0015] 1. The anti-slip mechanism actively presses the door panel with the friction belt driven by the first electric push rod, providing a driving force far exceeding that of traditional pure rolling friction. This allows the door panel to maintain synchronous movement with the conveyor line even when accelerating, decelerating, or encountering slight resistance, completely solving problems such as inaccurate displacement and stagnation caused by slippage. It is especially suitable for smooth metal door panels. The high friction between the friction belt and the door panel surface makes it play an active driving role to a certain extent, assisting the conveyor roller in pushing the door panel forward, reducing the load on the conveyor roller, and making the conveying more stable and efficient.

[0016] 2. By employing a position detector, PLC controller, and electric actuator in conjunction with the positioning mechanism, fully automated positioning is achieved. This allows the door panel to be repeatedly and accurately stopped at the preset processing position, ensuring the accuracy of subsequent processing (such as drilling and riveting). This fundamentally avoids batch processing defects caused by deviations in the door panel's stopping position, significantly improving product quality consistency and pass rate.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4 An elevator landing door panel processing and conveying device with an anti-slip structure includes a multi-roller conveyor frame 1 and multiple conveying rollers 101 disposed inside the conveyor frame 1. A base plate 9 is fixedly installed at the bottom of the conveyor frame 1, and an anti-slip mechanism is provided at the top of the conveyor frame 1. The anti-slip mechanism includes two symmetrically distributed support plates 2 fixedly installed on the upper end face of the conveyor frame 1. Each support plate 2 has a movable moving component 3 on its upper end face. The moving component 3 includes a first moving box 301 with an open side and a wedge-shaped second moving box 302. The first moving box 301 and the second moving box 302 are connected and their open sides face the conveying direction. The interior of the first moving box 301 is rotatably connected to two symmetrically distributed first rotating wheels 4, and the interior of the second moving box 302 is rotatably connected to a second rotating wheel 401. The two first rotating wheels 4 and the second rotating wheel 401 are triangularly distributed, and the outer walls of the two first rotating wheels 4 and the second rotating wheel 401 are jointly fitted with a friction belt 402 for pressing and conveying the door panel.

[0025] The top of the support plate 2 is provided with a drive mechanism that can drive the movable component 3 to move.

[0026] The tail end of the conveyor frame 1 is provided with a positioning mechanism, which includes a second electric push rod 6 and a blocking rod 701 driven to rise and fall by the second electric push rod 6, as well as a position detector 5 for detecting whether the door panel has reached the preset work position.

[0027] In this embodiment: the door panel (elevator landing door panel) is placed on a conveyor line composed of multiple conveyor rollers 101. The first electric push rod 201 is controlled by the PLC controller to move the moving component 3 toward the door panel. The friction belt 402 of the moving component 3 is pressed against the upper surface of the door panel. Since the surface of the friction belt 402 is provided with anti-slip protrusions, its friction with the surface of the door panel is extremely large, providing an additional forward auxiliary thrust, effectively overcoming slippage, ensuring that the door panel is conveyed forward smoothly and accurately, reducing the load on the conveyor rollers 101, and making the conveying more stable and efficient.

[0028] When the door panel detaches from the friction belt 402 and continues to be conveyed by the conveyor roller 101 to the preset processing station at the tail end of the conveyor frame 1, the position detector 5 (such as a photoelectric sensor) fixedly installed at the tail end detects the door panel. The position detector 5 immediately sends a signal to the PLC controller. The PLC controller sends a command to the second electric push rod 6 of the positioning mechanism according to the preset program. At this time, the second electric push rod 6 quickly pushes the moving plate 7 to rise smoothly, so that multiple blocking rods 701 rise from the conveying path. The front end of the moving door panel is immediately stopped after contacting the blocking rod 701, thus accurately stopping at the predetermined processing position and ensuring the positional accuracy of subsequent processing.

[0029] As a technical optimization of this utility model, the positioning mechanism includes a second electric push rod 6 fixedly installed on the top of the base plate 9, a movable plate 7 fixedly installed at the output end of the second electric push rod 6, and a plurality of front and rear distributed blocking rods 701 fixedly installed on the top of the movable plate 7.

[0030] In this embodiment: the second electric push rod 6 is activated after receiving a signal from the position detector 5, and its output end extends upward, pushing the moving plate 7 and the multiple blocking rods 701 installed on it to rise together. These blocking rods 701 distributed front and back form a "barrier" on the conveying path of the door panel, thereby reliably preventing the door panel from continuing to move forward and achieving precise positioning. The design of multiple blocking rods 701 ensures the uniform distribution of the blocking force and prevents the door panel from tilting due to single-point force.

[0031] As a technical optimization of this utility model, both the front and rear ends of the movable plate 7 are slidably connected to a U-shaped frame 8 fixedly installed on the top of the base plate 9.

[0032] In this embodiment: when the second electric push rod 6 drives the moving plate 7 to rise and fall, the front and rear ends of the moving plate 7 will slide in the groove of the U-shaped frame 8, which plays a guiding and stabilizing role, ensuring that the moving plate 7 and the blocking rod 701 move vertically without swaying back and forth or left and right, thereby ensuring the accuracy and reliability of positioning.

[0033] As a technical optimization of this utility model, a first electric push rod 201 is fixedly installed on the top of the support plate 2, and a pressure sensor is installed between the output end of the first electric push rod 201 and the first movable box 301.

[0034] In this embodiment: when it is necessary to press the door panel, the output end of the first electric push rod 201 extends and pushes the entire moving assembly 3 (first moving box 301, second moving box 302 and internal rotating wheel and friction belt 402) downward, so that the friction belt 402 presses against the door panel surface. The pressure sensor can detect the pressure of the friction belt 402 pressing the door panel. By controlling the extension length of the first electric push rod 201, the pressing force on the door panel can be precisely adjusted to adapt to door panels of different weights or surface conditions.

[0035] As a technical optimization of this utility model, two symmetrically distributed slide rails 202 are fixedly installed on the top of the support plate 2, and the bottom of the first movable box 301 and the second movable box 302 are provided with slide grooves 303 that are slidably connected to the slide rails 202.

[0036] In this embodiment: the slide rail 202 fixed to the top of the support plate 2 cooperates with the slide groove 303 to form a sliding pair. When the first electric push rod 201 drives the moving component 3 to move, the slide groove 303 will slide precisely along the slide rail 202, ensuring that the moving component 3 remains stable during the movement and will not deviate or get stuck.

[0037] As a technical optimization of this utility model, the outer wall of the friction band 402 is provided with anti-slip protrusions.

[0038] In this embodiment, the anti-slip protrusions on the outer wall of the friction belt 402 greatly increase the coefficient of friction between the friction belt 402 and the door panel surface, which can significantly enhance the anti-slip effect and provide a more stable and reliable conveying auxiliary force.

[0039] As a technical optimization of this utility model, the position detector 5 is fixedly installed on the top of the tail end of the conveyor frame 1, and a PLC controller is fixedly installed on the outer side wall of the conveyor frame 1. The position detector 5 and the second electric push rod 6 are both electrically connected to the controller.

[0040] In this embodiment, the PLC controller is the brain of the system. The position detector 5 monitors the conveyor line in real time and sends a "door panel arrival" signal to the PLC. According to the preset program, the PLC immediately sends a command to the second electric actuator 6 to control it to rise and block the movement.

[0041] The working principle and usage process of this utility model are as follows: The anti-slip mechanism is set at the anti-slip position of the conveyor line, and one or more sets can be set. The device is connected to an external power supply. In use, the door panel is placed on the conveyor line composed of multiple conveyor rollers 101. The first electric push rod 201 is activated by the PLC, which pushes the moving component 3 to move along the slide rail 202 toward the door panel. The two first rotating wheels 4 and one second rotating wheel 401 arranged in a triangle in the moving component 3 move accordingly. The friction belt 402 they are fitted together will press against the upper surface of the door panel. Since the surface of the friction belt 402 has anti-slip protrusions, its friction with the surface of the door panel is extremely large. When the door panel attempts to move under the drive of the lower conveyor roller 101, the friction belt 402 "grabs" the door panel through this static friction, providing it with an additional forward auxiliary thrust, effectively overcoming slippage and ensuring that the door panel is conveyed forward smoothly and accurately.

[0042] When the door panel detaches from the friction belt 402 and continues to be conveyed by the conveyor roller 101 to the preset processing station at the tail end of the conveyor frame 1, the position detector 5, fixedly installed at the tail end, detects the door panel and immediately sends a signal to the PLC controller. The PLC controller, according to a preset program, sends a command to the second electric push rod 6 of the positioning mechanism. At this time, the second electric push rod 6 rapidly rises, pushing the moving plate 7 to rise smoothly under the guidance of the U-shaped frame 8, causing multiple blocking rods 701 to rise from the conveying path, forming a reliable physical barrier. The front end of the moving door panel is immediately stopped upon contact with the blocking rod 701, thus precisely stopping at the predetermined processing position. After the door panel completes processing at the current station, the system PLC controls the second electric push rod 6 to retract, causing the blocking rods 701 to descend and release the obstruction. At this time, the door panel can be removed or, driven by subsequent equipment, continue to flow to the next station. The equipment returns to its initial state, awaiting the conveying of the next door panel.
