Description

Technical Field

[0001] This utility model relates to a horizontal machining center production line, specifically a safe and reliable horizontal machining center production line. Background Technology

[0002] With the development of industrial automation and the advancement of global trade, the demand for production efficiency of parts and components is constantly increasing. Production lines are a crucial part of ensuring production efficiency, and safe and reliable production lines are important factors in ensuring continuous and stable operation and personal safety.

[0003] Currently, common horizontal machining center production lines still have certain safety control vulnerabilities, mainly stemming from operator errors or violations. For example, when personnel need to load and unload materials at the loading / unloading station, if they illegally enter the loading / unloading station from the loading side or chip conveyor side during automatic operation, it could lead to serious consequences such as falls or being crushed by workpieces. The loading / unloading station area is also relatively prone to personnel violations. Furthermore, during production line operation, if personnel enter the transport vehicle track area through the protective gate or the main unit side without authorization, collisions between the transport vehicle and personnel are likely to occur. Such safety accidents not only threaten personnel life and property safety but also seriously affect the stability and continuity of equipment operation, leading to decreased production efficiency and increased operating costs for enterprises. In addition, current common horizontal machining center production lines often fail to meet the stringent safety standards required for European CE certification, which significantly restricts the competitiveness of horizontal machining center production lines in the international market and hinders enterprises from expanding their overseas business. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide a safe and reliable horizontal machining center production line that addresses the shortcomings of existing technologies. This production line ensures continuous and stable production, improves production efficiency, effectively isolates personnel from hazardous areas, and fundamentally reduces the risk of accidental injury. While achieving human-machine isolation and reducing safety accidents, it also reduces maintenance costs caused by unexpected downtime and equipment damage, providing a solution for enterprises to continuously reduce operating costs and improve production safety and reliability.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a safe and reliable horizontal machining center production line, which includes a horizontal machining center, a transport vehicle, a loading and unloading station, and a production line control cabinet. The horizontal machining center includes a main machine, an APC rotary table, and an exchange table. The processing area of ​​the main machine and the processing area of ​​the production line are separated by a first lifting door. The processing area is equipped with a fence, and protective gates are installed on both sides of the fence. Several storage spaces are arranged on the inner and outer sides of the fence for storing the exchange table. A track is laid inside the fence, and the transport vehicle is slidably installed on the track for transporting the exchange table. The loading and unloading station is located on one side of the fence, and a second lifting door is installed between the loading and unloading station and the fence. The loading and unloading station includes safety protection. The system includes a loading / unloading station workbench, a workbench rotation and push-pull mechanism, a loading / unloading station operation panel, and a light strip. The safety protection device includes a front light curtain, a rear light curtain, and a magnetic switch. The front light curtain is located on the loading side of the loading / unloading station, and the rear light curtain is located above the second lifting door. The magnetic switch is installed at the chip discharge port of the loading / unloading station and is used to detect whether the chip discharge cart of the loading / unloading station is closed in place. The workbench rotation and push-pull mechanism is used to realize the rotation or push-pull action of the loading / unloading station workbench. The loading / unloading station operation panel and the light strip are respectively installed on the loading side of the loading / unloading station. The loading / unloading station operation panel is equipped with a first emergency stop button and a light curtain reset button. The light strip is used to display different working states of the loading / unloading station through different colors. The production line control cabinet is used to control the coordinated operation of the horizontal machining center, the transport cart, and the loading / unloading station.

[0006] This utility model relates to a horizontal machining center production line. A first lifting door separates the machining area of ​​the main machine from the waiting area of ​​the production line, preventing chips generated during workpiece processing from entering the waiting area. Simultaneously, a fence forms a hard barrier, effectively protecting the exchange worktable, transport vehicles, etc. A second lifting door separates the loading / unloading station area from the fenced area, preventing personnel from entering the fenced area from the loading / unloading station. A front light curtain prevents personnel from entering the loading / unloading station from the loading side, and a rear light curtain prevents personnel from stepping on workpieces placed in the loading / unloading station and entering the fenced area. When a person triggers either the front or rear light curtain, the production line stops working. At this time, pressing the light curtain reset button is required for the production line to restart normally. When a magnetic switch is triggered, the production line also stops working and needs to be restarted.

[0007] As a preferred implementation, the production line control cabinet can use high-reliability components that meet internationally recognized safety standards (such as UL, VDE, or CE directives) to ensure the safe and compliant operation of the entire production line. This effectively compensates for the deficiencies in safety control of existing horizontal machining center production lines, significantly reduces safety risks, and meets the stringent safety standards of European CE certification, thereby helping to enhance the international market competitiveness of the product.

[0008] Preferably, the protective gate is equipped with a gate operation panel and a gate lock. The gate operation panel has a second emergency stop button and a door interlock release button controlled by the production line control cabinet. The gate lock has a manual opening button located on the inside of the fence. The design of the gate lock, second emergency stop button, door interlock release button, and manual opening button further improves the safety of the production line and facilitates personnel escape from inside the fence.

[0009] Preferably, a control cabinet is installed on the underside of the transport vehicle, and the control cabinet is equipped with a manual operation panel and a third emergency stop button. In the event of accidental entry of personnel into the enclosure, this third emergency stop button can be triggered immediately to stop the transport vehicle quickly, thereby effectively controlling the risk and eliminating safety hazards.

[0010] Compared with existing technologies, this utility model has the following advantages: The horizontal machining center production line of this utility model has high safety and operational reliability. The production line integrates multiple safety protection designs in its overall layout, preventing personnel from accidentally entering the loading / unloading station and the transport vehicle operating area. It ensures continuous and stable production, improves production efficiency, effectively isolates personnel from dangerous areas, and fundamentally reduces the risk of accidental injury. While achieving human-machine isolation and reducing safety accidents, it also reduces maintenance costs caused by unexpected downtime and equipment damage, providing a solution for enterprises to continuously reduce operating costs and improve production safety and reliability.
