A. Kempf

勝斐邇承攬 A. Kempf Getränkegroßhandel GmbHSI(肯普夫公司)的物流配送中心改造工程,結合無線射頻識別標籤系統(RFID)應用在關鍵的子流程吞吐量。植入 軟體介面的設置在一周內運作完成。並,這個自動無線射頻識別標籤系統解決方案為肯普夫公司每天節省8個人的工時。

內部物流是各部門優化生產力和有效率利用資源的關鍵。根據產業在經過了七至十年後,倉庫逐漸變的陳舊:有需淘汰的、破舊的及功能不足的。現代化設施可以提昇優化潛力高達30%。及包括資訊及確認技術,可提早看見節約和效益優勢。以位於德國歐芬堡的 A. Kempf Getränkegroßhandel GmbH 肯普夫公司為例。

自2002年以來,A. Kempf Getränkegroßhandel GmbHSI(肯普夫公司)一直是德國 Edeka Handelsgesellschaft SüdwestmbH (埃德卡公司)的全資子公司,為德國西南地區的食品零售業提供飲料配送服務。該公司在Offenburg(奧芬堡)和Balingen(巴林根)各擁有一個物流配送倉庫,每天配送125個客戶達110車次。在旺季時,每天有高達174,000產品以完整包裝方式從配送中心出貨。為了適應淡旺季出貨量的波動,該公司希望重整位於巴林根的飲料物流配送倉庫,以自動化方式執行出貨作業。倉庫重整以能適應未來的成長、實現廣泛的成本和作業流程改善為目標。為了達成這些目標,該公司選擇勝斐邇來執行此一專案。

內部物流專家推薦該公司使用有分流功能的動態流利架系統給出貨區用。在12層深巷道儲存系統中此訂單緩衝區有1, 152個棧板儲位提供給預先揀取訂單的棧板,及巡迴的棧板緩衝區內提供額外的720個棧板位置剛好是16部卡車裝載的量。類似的裝載過程中,來自訂單緩衝區的編輯巡迴緩衝是在巡迴緩衝區完成。 “隨著二層物品出貨邏輯的自動化和實施,我們能夠減少卡車在堆疊場吞吐量的時間,從最多四個小時到現在不到一個小時完成”肯普夫的巴林根的配送中心運營經理帕特里克解釋。由系統啟動訂單及編輯巡迴由廠區設計,肯普夫已經實現了從每小時90棧板增加到每小時240棧板的吞吐量。出貨緩衝區的容量增加了近一倍。

肯普夫公司依賴已被證實可用的條碼技術和掃描器。 Zurheide解釋說:“我們有信心,這是依據我們的流程所需要的正確的確認基礎。”雖然供應儲存,庫存轉移,出貨和出貨緩衝區是有效的,揀貨堆高機及堆高機在飲料倉庫內匯編訂單。每班使用六到八台的四輪堆高機,16台室內堆高機和30台揀料車。完成揀貨的棧板藉由輸送帶通過二層樓板進入雙棧板進料站。該系統將棧板自動引入至兩層式的出貨緩衝區的過程。訂單棧板及全部產品藉由通過第三個進貨口進入的通道存儲系統。

堆高機駕駛者和揀貨者透過無線網路從倉庫管理系統(WMS),取得他們需要揀貨的訂單資訊。在過去,要確認棧板已輸送進入三個進貨站的輸送系統,僱員必須掃描棧板上條碼以及進貨台本身的條碼。揀貨者掃描過程需約10秒鐘,堆高機駕駛員需約15秒鐘。 “這些都是我們與自動化系統的性能相較之下人工掃瞄的動作很容易被認定為損失更多時間的原因”Zurheide解釋。 “因此,我們尋找一個自動識別解決方案。我們當時的想法是想獲得資料與RFID技術。所以我們聯繫了SSI-SCHAEFER勝斐邇有限公司如何來實現這一點。

RFID體積小,無電池,記憶體由一個發射器和一個接收器組成。無線射頻識別標籤系統對於內部物流變得越來越重要。RFID的接收器,也被稱為標籤或晶片,可以被單獨編碼。與條碼不一樣的是RFID的數據記憶體可提供更高的容量。它們不需目視接觸便可以是讀出內部資訊。只要發射機在接收機的範圍內,它可以讀取和獲得數據資料。

One year after completing the restructuring of the distribution center, SSI Schaefer received the order to retrofit the in-feed station to RFID-technology. “We wanted to develop an optimal solution that allowed for continuous picking processes without time-consuming scanning processes at the pallet transfer,” explains Dominik Kampf, Service Account Manager at SSI Schaefer. “After the RFID-technology was set, we generated the necessary design, hardware and IT-interfaces to efficiently accommodate peak seasons and longterm growth.”

The hardware solution provided included three industry-standard UHF-RFID-read/write units, known as interrogators. They are used in the identification of body components in automobile production or at the backtracking of transport totes, among other things. With SSI Schaefer’s solution for Kempf, the interrogators are used to capture the picking vehicles and forklifts at the three pallet in-feed stations. Parallel to that, the Kempf employees receive an individual identification card with a RFID-chip that acts as a passive transponder. Data transfer is done via load or frequency modulation, and all material handling vehicles used for the pallet transfer are equipped with a special holder for the employees’ chip cards.

When dealing with metals and liquids the capture of RFID-signals is often impaired, making it difficult to display the information completely. For Kempf, a RFID-solution had to be developed which also supplied solid results even under these extreme conditions. “We used transponders and read units working in the high-capacity, ultrahigh frequency range of 869 MHz according to the Ultrahigh Frequency (UHF)-standard of the European Telecommunication Standards Institute (ETSI),” says Kampf. “With that, the data exchange is possible in the vicinity of liquids and metals.”

At the beginning of every shift, employees log in at their vehicle terminal and insert their chip card in the holder. During the shift, the WMS sends the respective picking and transport orders to the terminal. The employees then report the completion of the storage pallets to the WMS via the terminal which generates a telegram that is sent to the material flow computer. At that time, the material flow computer supplies the interrogators at the in-feed stations with individual pallet information, as well as employee identification details. From there, the read/write units know that a pallet transfer is pending and are expecting the arrival of material handling devices. At the transfer of the pallets onto the conveying system, the RFID-transponders within the chip cards are identified without any employee effort and the pallets are forwarded into the automated processes. “Transfer times are reduced from 10 or 15 seconds to two seconds each with RFID-capture”, summarizes Zurheide. “This is a sum of up to eight man-hours per day.”

Due to intensive preliminary work, SSI Schaefer was able to implement the retrofit project during running operation within one week. There were two days allotted for assembly and hardware installation, and five days for the successive modification of the IT. “First, we implemented data capture at the three in-feed stations in parallel with the barcode and RFID-system operation. Then we modified each of the three in-feed spurs to the RFID-solution”, explained Zurheide. “The entire in-feed processes are now running via RFID in a stable and error-free environment. With the RFID-solution we have further optimized the transfer processes and adjusted it to the high throughput capacity of our new system.”
