ZRAY Releases Multi-Size Adjustable Carton Erecting Machine (3–5 min Changeover, L 200–550 mm Range) with Quick-Changeover System | ZRAY
Most case erectors lock an operator to one carton size per shift. In multi-SKU plants — contract packers, e-commerce and food lines — changeover, not speed, is the bottleneck. Handwheel adjustment of guides, platen and tape head costs 15–25 minutes per change. Three changes per shift means up to 75 minutes of dead time daily, about 375 lost hours per year on two shifts. ZRAY’s new multi-size adjustable carton erecting machine attacks this loss with a digital quick-changeover system built on SMED principles, cutting changeover from 25 minutes to 3–5 minutes.
How the Changeover Time Falls from 25 to 5 Minutes
| Step | Traditional | ZRAY quick-change |
|---|---|---|
| Side guide | 4–6 min | 0.5 min, quick clamp |
| Platen | 5–8 min | 1 min, quick-release |
| Height / length | 4–6 min | 1–2 min, digital handwheel |
| Tape head | 3–5 min | 0.5 min, tool-free clasp |
| 1st-piece check | 2 min | 0.5 min, auto check |
| Total | 15–25 min | 3–5 min |
The core mechanism pairs a digital counter handwheel with colour-mark scales, so each axis reads a number instead of a feel. Plates use a tool-free clasp and side guides slide on a quick-adjust rail — no spanner, no shim, no re-squaring by eye.
Adjustable Size Range and Board
| Range | Min | Max |
|---|---|---|
| Length (L) | 200 mm | 550 mm |
| Width (W) | 150 mm | 400 mm |
| Height (H) | 120 mm | 500 mm |
| Thickness | 3 mm | 9 mm (pre-crease 11 mm) |
| Flute / layers | B, C, E / 3-layer; BC, EB / 5-layer | |
| Weight | 350 g/m² | 1 000+ g/m² |
Flute direction stays vertical; board above 9 mm needs pre-creasing and a de-rated 30 CPM.
Recipe Management and Barcode Setup
Each size is stored as a recipe on the 7″ HMI (up to 100). The operator scans the job barcode and servo axes drive to stored dimensions, then the HMI runs a first-piece check. This removes the biggest changeover error: a wrong dialled number.
Post-Changeover Checklist
| # | Check | Pass criterion |
|---|---|---|
| 1 | Magazine / guides | Snug to board, skew ≤ 1 mm |
| 2 | Platen gap | Board + 0.5 mm |
| 3 | Tape offset | ±1.5 mm |
| 4 | Flap overlap | ≥ 50 mm |
| 5 | Squareness | ≤ 2 mm |
Alarm Codes Linked to Changeover
| Code | Description | Field action |
|---|---|---|
| AL-02 | Magazine empty | Re-square guides to board |
| AL-03 | Pickup miss | Re-check platen, humidity |
| AL-04 | Forming jam | Re-set platen to board + 0.5 mm |
| AL-06 | Flap not closed | Adjust roller 15–20 N |
| AL-08 | Conveyor overload | Clear downstream, re-tension |
Preventive Maintenance Schedule
| Interval | Tasks |
|---|---|
| Daily | FRL drain; 0.5–0.6 MPa; vacuum filter; cups |
| Weekly | Lube guides; belt; sensors; guides |
| Monthly | Vac filter; belts; frame bolts; calibrate |
| Quarterly | Cups; PLC I/O; gearbox; blades |
| Annually | Gearbox oil; bearings; insulation; re-level |
Capacity Payback
At 25 CPM a 20-minute changeover wastes ~500 cartons. Cutting to 4 minutes recovers ~480 minutes per shift over three changes — ~1 440 cartons — and ~360 hours per year on two shifts, the fastest payback for e-commerce, food and daily-chemical lines.
If your cartons arrive as three-piece blanks, see our Three-Piece Case Erector. For single-piece RSC runs, the Single-Piece Case Erector shares the same philosophy.
