The single-layer grid chute for small items is centered around gravity sliding to transport small packages. In special circumstances, pre control measures are prepared around scenarios such as material blockage, overflow, abnormal shapes, loose equipment structure, environmental changes, emergency switching, etc., to reduce the risk of mainline stoppage, package damage, and personnel collision, and ensure that the sorting chain can be quickly handled and restored. The specific preparation contents are as follows:
1. Emergency preparedness for material blockage and package jamming
Install material blocking photoelectric detection and sound and light alarm devices at the entrance, middle section, and bottom of the chute; Prepare specialized clearing tools in advance (plastic push rods, anti slip gloves, hard and sharp tools are prohibited); The system pre-set the logic of locking the slot and diverting packages to the backup abnormal slot; Clarify the clearance operation process in advance, coordinate upstream shutdown before clearance, and prohibit reaching out to take out bags while running in the chute to prevent injury.
2. Preparation for warehouse explosion, overflow and overload
Set up full material detection at the bottom of the grid, automatically alert and pause feeding to the chute when the accumulation threshold is reached; Plan in advance for backup containers, turnover cages, and temporary diversion channels; Set up an overflow diversion scheme to avoid stacking packages too high and blocking the entrance of the chute in reverse, and to prevent chain jamming from affecting the upstream sorting main line; During peak hours, additional on duty personnel will be dispatched to conduct targeted inspections of high flow grid entrances.
3. Preparation for adaptation of irregular, oversized, and vulnerable parts
Clear the upper limit of the size of small items that can be passed through the chute in advance, and set up separate abnormal removal channels for packages that are too thick, soft, have protruding pendants, and are prone to slipping; Reserved flexible buffer pads and anti slip lining plates for quick installation on the inner wall of the chute; Prepare buffer protection accessories in advance for the compartments corresponding to fragile and high-value small items, reducing the probability of high-speed sliding impact damage; Wet water and adhesive packages are separated separately to avoid sticking to the inner wall of the chute and causing continuous jamming.
4. Preparation for Structure and Safety Protection
Regularly inspect the sliding groove bolts, support brackets, and splicing joints, prepare fasteners of the same specifications, and repair plates; Install protective barriers and fall nets at the edges and drop positions of the chute; Reserved operating platform for high-altitude chute maintenance position; Emergency stop points and warning signs should be kept intact and clear; In response to cracking of the chute and deformation of the board, temporary sealing and module replacement are prepared, supporting quick disassembly and replacement.
5. Preparation for special working conditions such as temperature, humidity, and environment
Prepare wiping tools and drying equipment in advance during humid and rainy seasons to prevent packages from slipping and staying in the trough; Verify the friction coefficient of the sliding groove lining in a low-temperature environment and replace the low friction lining plate if necessary; Check whether there is a risk of softening and deformation of plastic parts in high temperature environments; Outdoor chutes should be covered with rain to prevent rainwater from accumulating, soaking, and wrapping inside the chute.
6. System switching and business backup preparation
Pre configure chute fault markers and bypass switching functions in the automatic sorting system; When a single chute fails, the flow of the package can be switched to a backup grid or a manual processing station; Prepare paper waybill registration and manual sorting ledger, deal with power outages and system crashes throughout the line, ensure traceability of abnormal items, and prevent misclassification and loss of items.
7. Preparation of personnel and work plan
Provide training to on-site personnel on card blockage clearing, emergency stop operation, and isolation of damaged parts; Clearly define the fault reporting path and graded disposal time limit; Configure basic protective equipment, distinguish between different levels of abnormalities such as general blockage, large blockage, structural detachment, etc., to avoid improper handling and expansion of faults.
8. Post audit and spare parts reserve
Common vulnerable parts: wear-resistant lining plate, buffer rubber strip, fixed buckle, photoelectric sensor; After each abnormal handling is completed, record the causes of the card package (package type, stacking position, tilt angle issue), optimize the chute tilt angle and inlet guide structure in a targeted manner, and reduce the recurrence of similar problems.
