No need to decode model codes — answer a few questions about your operation and the system returns the recommended models and full machine code for upstream induction, the identification section (DWS) and downstream sorting, following Jaytom's tier-selection rules. All rules come from Jaytom's confirmed technical specifications and measured project data, not from estimates.
The essence of full-line selection is to fix each level in the order “parcel type → recognition → induction → sorting”. Each step answers only one key question, which brings the chance of a mismatch down to the minimum.
First measure three things:max single-item weight、Maximum parcel length、Peak throughput requirement. These three determine all tiers below.
The grade is set in five steps: drive boundary (30 kg), scale length formula, single / dual scale, number of vision faces and buffer section, which outputs the complete JT-DWS machine code.
Set the number of transverse rows n by belt width and the number of longitudinal rows m by the degree of stacking; outputs the SGL model and the footprint of the whole line.
Small and medium parcels at high speed → cross-belt ZX; medium/large or irregular → wheel divert BL; flat parcels at branch offices → Z-type shuttle. Specify by parcel type and number of destinations.
Select according to actual site conditions; results refresh instantly. The output is a complete machine code that can be used directly for proposals and quotations.
Go directly to the selector by product— To view a single machine on its own, skip the four steps and click any item below to open the selection/demo screen for that product.
Already have a JAYTOM model code? Paste it in to decode its configuration segment by segment — tabletop / disc type / belt width, chutes, servo stages, throughput, power and footprint, all in one read. Supports SGLsingulator, ZXmodule-belt sorter, BLpop-up wheel sorter, JT-DWSDWS scanning unit, MAFive product lines of manual-assisted sorting stations; case-insensitive, and both × / x notations are accepted.
※ Reverse-lookup results are parsed segment by segment per JAYTOM's finalized specification. Items marked ⚠ are non-compliant or non-standard combinations — confirm with technical staff before ordering. Final specifications are subject to the technical agreement.
※ The selector calculates per Jaytom's confirmed criteria; final specifications are governed by the technical agreement. Throughput is a theoretical equipment-side figure; actual capacity depends on parcel mix, gap and upstream induction rate. For engineering purposes, apply a 0.8 factor.
Below are Jaytom's finalized model-selection rules, ready for direct use in solution review.
| Step | Decision basis | Conclusion |
|---|---|---|
| ① Drive type | Maximum single-item weight | ≤30 kg → direct-drive motor roller (E); >30 kg → servo motor (S) |
| ② Weigher length | Scale length − 250 × line speed ≥ longest parcel length (375 mm deducted at 1.5 m/s) | 1000 / 1600 / 1800 / 2000 — take the smallest sufficient grade |
| ③ Single / dual weigher | Throughput >4000 parcels/h, or a high share of long items | One scale is enough, no waste; for >4000 use dual scales (D1600 / D2000) |
| ④ Number of scan faces | Barcode orientation and tipping probability | Parcels that may flip over → top-scan V1; occasional flips → five-side V5; soft mail bags → six-side V6 |
| ⑤ Buffer section | Downstream equipment type | 1500/2000 is mandatory when connecting to a wheel divert sorter; never fitted when connecting to a cross-belt sorter |
| items | Rules |
|---|---|
| First set n (transverse rows) | Derived from the belt width: 600 → n=4 (200 carriers); 800 → n=4; 1000 → n=5; 1200 → n=6 |
| Then set m (rows along the direction) | By degree of stacking: standard m=4; severe stacking m=5~6; limited space m=3 |
| Capacity formula | Q = release speed ÷ (average parcel length + target gap) × 3600; engineering capacity = Q × 0.8 |
| What sets the capacity limit | Determined only by three quantities: speed v, item length L, and clear spacing d; increasing the belt width or the number of chutes NoHigher throughput |
| items | Rules |
|---|---|
| Main category (by item type) | Standard medium and large items →Large-wheel divert(φ200 large disc + φ120 small disc); many small items, requiring good small-item passage →Direct-drive divert(all φ120, close-packed) |
| Servo zone count (by throughput) | 1 section 3800 · 2 sections 5000 · 3 sections 6000 · 4/5 sections 6500 parcels/h (rated for 400×400 parcels) |
| Model notation | BL-{docking width}M{no. of large wheels}D{no. of small wheels}-{N}S; the direct-drive version writes only the D segment; the close-packed version places B before the segment; N = number of servo groups (1~6) |
| items | Rules |
|---|---|
| Slat chain width | 300 / 400 / 500 / 600 / 800 mm, determining which parcel types can pass (the longest side must not exceed the chain slat width) |
| Chute length | 750 / 1000 / 1200 / 1500 / 2000 mm — take the smallest sufficient grade for the parcel type |
| Number of chutes | 3–20 per side (40 on both sides at most), determined by the number of sorting lanes; each additional lane means one more central sorting section |
| Model notation | ZX-{chute length}-{O head and tail section / I central sorting section}-{chain slat width} |
These are the pitfalls most easily hit on site; checking them once at the proposal stage saves a great deal of rework.
| Wrong configuration | Consequence | Correct practice |
|---|---|---|
| Connecting to a wheel divert sorter without a buffer section | Chute data has not returned while the parcel has already passed the sorting zone → “recognized but cannot be routed out” | A buffer section is mandatory: 2000 if space allows, otherwise 1500 |
| Fitting a buffer section when connecting to a cross-belt sorter | Duplicated investment and wasted space | The 1750 mm cross-belt head section includes a buffer as standard and is always omitted |
| Motorized roller solution for 50 kg parcels | Roller overheating, gear tooth breakage, stall | >30 kg: switch to the servo drive — this cannot be solved by raising power |
| Higher speed with unchanged weigher length | Sampling window compressed → larger weighing deviation and higher missed-weighing rate | Recalculate by Lmax = scale length − 250×v; lengthen the scale or switch to dual scales if necessary |
| The servo long weighing platform still uses 750 W | Sluggish start/stop, longer time to reach steady speed, sampling window cut short | Scale length ≥1600 → 1.0 kW; heavy-load high-speed combination → 1.5 kW |
| No item singulation upstream | Clustered inbound items cause duplicated numbers, missed scans and crossed weighing records | Before the DWS, single, ordered items with a clear gap must be guaranteed (≥400 mm recommended) |
| Oversized items forced onto a standard scale | The largest dual weigher D2000 has an effective window of only 1625 mm; parcels longer than 1625 mm suffer missed weighing and scanning failures | If item length > 1625 mm, reduce line speed v to widen the window, or use a custom extended weighing bed; do not place the order directly |
