From trader to steel service centre

With more than 6,000 loading and unloading operations per month and shipping in four shifts, six days per week, Becker Stahl-Service in Bönen, Germany, provides just-in-time deliveries to satisfy its customers' wishes.

该公司是一家钢铁贸易商,总部位于Unna-Bönen,现已发展成为一家拥有400多名员工的钢铁服务中心,销售、储存、处理和加工钢铁。

产品范围包括宽幅带、狭缝带betway88娱乐、板材、坯料和梯形坯料,有多种饰面和涂层。由于其60%以上的产品是为汽车和汽车供应行业的客户生产的,供应商必须满足这一行业的高要求质量和生产标准。

An annual sales volume of some 1 million tonnes combined with stocks of approx. 200,000 tonnes and short production lead times has made the supplier a leader in the European steel trade sector. The company has been part of the Klöckner Group since 2010.

由于磁力提升设备,存储容量增加

在Becker Stahl Service的仓库中运行的起重机是内部物流系统的主要组成部分,将生产、储存和运输业务相互联系起来。它们对整个过程的效率和灵活性有很大的影响。起重机的最大可能可用性具有最高优先级。两台Demag Coilmaster工艺起重机负责Becker钢卷的半自动和全自动搬运。因此,二级起重机系统也可确保可靠运行。起重机1以全自动模式为线圈库提供服务。起重机2在半自动控制下运行,用于装卸进货卡车以及为仓库的前部区域(检疫区)提供服务。该起重机也可在自动模式下运行。必威体育

The load handling attachment is innovative: Demag process cranes are being used with coil magnets for the first time in a coil store:

  • 对可用空间的最佳利用:由于负载是从上方拾取的,因此钢卷之间的存储间隙仅为300 mm。这使商店的有效利用率提高了约30%。
  • 温和的处理负载:磁铁系统存在ures that the heavy, but also fragile, steel coils are handled carefully. Strategies can be configured to achieve the best possible placement of the relevant coils in the store – also in three-level stacks.
  • 高水平的安全性:除了激光控制的起重机和螃蟹定位系统外,两级切断操作的光屏障也确保起重机之间保持安全距离。起重机防撞系统由安全控制系统监控,该系统规定类别3.
  • Optimum efficiency: the store operates 24/7 without interruption with the highest possible efficiency. The required handling rates are achieved with the Demag warehouse management system, which is integrated into the host system infrastructure at Becker Stahl-Service.
  • Kind to resources: in addition to optimum utilisation of the available space, the crane systems also perform well in terms of power consumption. The energy recovered when loads are lowered is fed back into the in-house power supply system, which helps to reduce power consumption and the operating costs of the installation.

工艺步骤

Before the coils enter the store

The material is delivered to and shipped by truck at the Becker Nord facility. The goods are lifted off the trucks and deposited in the quarantine zone by the Coilmaster crane under manual control. In this area, the goods are registered, i.e. labelled and issued with a coil record document . The coil data are transferred to the warehouse management system and the ERP system (Baan), where the data are compared with the specifications saved in the system.

A sample of every coil is cut for quality assurance. The data available at Becker goes all the way back to the steel supplier, which enables all physical and chemical coil data to be accessed.

安全可靠地提取线圈

质量保证检查完成后,在手动控制下,用起重机将线圈运输到转移点进行自动处理。当磁铁接合负载时,激光束检查以确保线圈位于磁铁的中心。如有必要,在横向行驶方向上进行校正。这可确保仓库中的自动起重机精确地拾取和定位负载。磁铁的运行有两个安全级别:在第一阶段,负载被磁化并以爬行速度升高。当磁铁安全接合时,系统自动切换至满载模式,并以最大提升速度提升负载。

转移到自动起重机

在转移点,操作员将起重机切换到自动模式。仓库管理计算机(WMC)在自动区前面的隔离存储区内指定一个位置。线圈移交后,起重机返回隔离区,等待下一次卸货操作。

WMS将存储任务分配给自动起重机1包括源坐标和目标坐标的详细信息。通过使用激光传感器,起重机将起重机精确定位在线圈上方并将其提起,同时起重机称重装置测量线圈的准确重量。提升装置将磁铁和负载提升至最高吊钩位置,在此位置它们与机械导轨接合,以防止任何负载摆动。然后,自动起重机以最大速度移动到预定义的存储位置,并将线圈转移到存储位置。

Store structure

The store was designed according to geometric conditions. The widest coils are stored in the outer lines to utilise the crane approach dimension at the edge of the store. The warehouse management computer is aware of the dimensions, surface finish and grade of the materials. This enables the system to store the items appropriately.

线圈靠在所谓的线圈块上,线圈块反映了不同的宽度和直径。考虑到各种类型材料的存储策略,包括堆放物品的多阶段限制,例如,确保最大限度地利用可用空间以及安全可靠地处理材料。

Retrieval processes

Items are retrieved as required in production or to customer order according to a coil staging list. Items are transferred to production via cross-shaped turntables, which represent the interface between the store and the machines. The process crane deposits the coils and reports completion of transfer to the machine tools via a „handshake“ procedure. Partly used coils are also returned to the automated zone together with a data module via the turntable. To do this, the crane determines the current weight of the coil by means of an integrated weighing device.

Production and finished goods store

贝克斯塔尔服务has installed cut-to-length and slitting lines in bays 12 and 13, which are located immediately next to the store. Four manually operated Demag ZKKE double-girder overhead travelling cranes, which are equipped with radio controls, are used for handling the products in these production bays.

13号海湾配备了一台35吨的起重机和一台28吨的起重机。这两台起重机都使用C形钩来搬运狭缝带。两台20吨重的起重机配备DR-Pro缆绳起重机和抓斗,用于搬运托盘货物,在邻近的12号海湾作业,加工厚度达4毫米的金属板。
