Giới thiệu hệ thống Kệ Pallet Flow (Pallet Flow Racking)
Kệ Pallet Flow (hay còn gọi là Kệ dòng chảy) là giải pháp lưu trữ hàng hóa tự động hóa cao. Giống như người anh em [Kệ Carton Flow] (dùng cho hàng nhẹ), Kệ Pallet Flow sử dụng các thanh ray chứa con lăn (rulo) để vận chuyển các pallet hàng nặng hàng tấn.
Đây là sự kết hợp hoàn hảo giữa mật độ lưu trữ cao của [Kệ Drive-In] và khả năng luân chuyển hàng hóa tuyệt vời của Kệ Selective.
Thông số kỹ thuật “Chuẩn Unirack”
| Tiêu chí | Thông số kỹ thuật |
| Tải trọng | 1000 – 3000 kg/pallet |
| Độ nghiêng sàn | 3% – 4% (Góc nghiêng tối ưu) |
| Hệ thống con lăn | Con lăn thép mạ kẽm cường lực |
| Hệ thống phanh | Có phanh hãm tốc độ (Brake rollers) an toàn |
| Phương thức lấy hàng | Xe nâng các loại |
| Quy tắc xuất nhập | FIFO (Nhập trước Xuất trước) |
| Màu sắc | Xanh – Cam (Sơn tĩnh điện) |
| Bảo hành | 5 năm |
Nguyên lý hoạt động và Hệ thống Phanh an toàn
1. Cơ chế trượt tự động
Các làn kệ được thiết kế nghiêng một góc nhỏ (khoảng 3-4 độ). Pallet được xe nâng đặt vào đầu cao (lối nhập), sau đó tự động trượt từ từ về phía đầu thấp (lối xuất) nhờ trọng lực.
2. Hệ thống kiểm soát tốc độ (Cực kỳ quan trọng)
Với tải trọng hàng tấn trượt trên dốc, nếu không có kiểm soát, pallet sẽ lao đi rất nhanh gây nguy hiểm.
Unirack trang bị hệ thống Con lăn phanh (Speed controllers) đặt đan xen trong đường chạy. Thiết bị này giúp kìm hãm tốc độ, đảm bảo pallet trượt đi nhẹ nhàng và dừng lại an toàn tại điểm lấy hàng.
Tại sao Kệ Pallet Flow là “Vua” của kho hàng thực phẩm?
1. Quản lý hạn sử dụng (Date) tuyệt đối
Nhờ tuân thủ nghiêm ngặt quy tắc FIFO, pallet nào nhập vào trước sẽ trượt ra để xuất trước. Đây là tính năng sống còn đối với các ngành hàng FMCG (Hàng tiêu dùng nhanh), thực phẩm, sữa, dược phẩm.
Giải pháp tối ưu cho ngành hàng FMCG cần tốc độ luân chuyển nhanh.
2. Tiết kiệm nhân công và nhiên liệu
Xe nâng không cần chạy sâu vào trong kệ (như Drive-In) hay chạy dọc theo các lối đi dài. Chỉ cần đứng ở đầu kệ để nhập/xuất. Điều này giúp giảm quãng đường di chuyển của xe nâng, tiết kiệm xăng/điện và nhân công lái xe.
3. Tối ưu diện tích kho lạnh
Chi phí vận hành kho lạnh rất đắt đỏ. Pallet Flow giúp tận dụng tối đa thể tích kho lạnh, giảm thất thoát nhiệt do ít phải mở cửa kho thường xuyên (do xe nâng ít di chuyển).
So sánh Kệ Pallet Flow và Kệ Drive-In
Cả hai đều tiết kiệm diện tích, nhưng mục đích sử dụng lại khác nhau:
| Tiêu chí | Kệ Drive-In | Kệ Pallet Flow |
| Quy tắc | LIFO (Vào sau ra trước) | FIFO (Vào trước ra trước) |
| Chi phí đầu tư | Thấp hơn | Cao hơn (Do hệ thống con lăn & phanh) |
| Tốc độ vận hành | Trung bình | Rất nhanh |
| Hàng hóa phù hợp | Hàng lưu kho lâu, ít hỏng | Hàng có hạn sử dụng ngắn (Date) |
Báo giá lắp đặt Kệ Pallet Flow
Do cấu tạo phức tạp với hệ thống con lăn và phanh hãm nhập khẩu, chi phí đầu tư Kệ Pallet Flow thường cao hơn các loại kệ tĩnh. Tuy nhiên, hiệu quả ROI (Hoàn vốn) mang lại từ việc tiết kiệm nhân công là rất lớn.
