Automatic vs semi-automatic rigid box machines

Which steps stay manual on a semi-automatic rigid box line

Gluing and wrapping are done by machine in both cases. What changes is the handling between them. On a semi-automatic line an operator places each taped shell on the glued sheet by eye, against printed marks, and feeds the forming machine. On an automatic line a camera reads the sheet and a robot arm places the shell.

Three levels of automation, step by step

For a lid-and-base rigid box there are three ways to equip the same five operations. The middle one is often overlooked: it keeps the separate machines of a semi-automatic line and automates only the positioning.

Corner pasting: HF-40 manual vs HF-500 automatic

Manual and automatic corner pasting machines.

Parameter	HF-40	HF-500
Speed	10–20 pcs/min	30–55 pcs/min
Largest box	500 × 450 × 150 mm	480 × 450 × 150 mm
Smallest box	40 × 40 × 10 mm	45 × 45 × 10 mm
Power	0.75 kW / 220 V	2.5 kW / 220 V
Weight	180 kg	1,000 kg

The two machines take almost the same range of boxes. The difference is the stroke: the HF-40 tapes one corner each time the operator presents the shell, and the HF-500 tapes all four at once. Four corners in one stroke also means the four are taped identically, which cuts rejects at the wrapping step.

Forming: HF-450 line vs HF-5040 automatic machine

A forming machine fed by hand against the all-in-one automatic machine.

Parameter	HF-450	HF-5040
Speed	15–20 pcs/min	18–25 pcs/min
Largest box	480 × 400 × 120 mm	500 × 400 × 120 mm
Smallest box	45 × 45 × 15 mm	65 × 65 × 20 mm
Positioning accuracy	—	±0.1 mm
Motor or heating power	2.5 kW / 220 V	15 kW / 380 V, 3-phase
Footprint (L × W × H)	1400 × 1100 × 2050 mm	8200 × 4200 × 2150 mm

Box-to-case assembly: HF-808 vs HF-8288

Semi-automatic and automatic assembly of an inner box onto a case.

Parameter	HF-808	HF-8288
Speed	15–22 pcs/min	15–22 pcs/min
Largest cover	980 × 450 mm	960 × 440 mm
Power	6 kW	8 kW
Weight	600 kg	1,200 kg
Footprint (L × W × H)	3200 × 1000 × 1850 mm	5550 × 2300 × 2200 mm

Both assembly machines are rated at 15–22 pieces per minute. They differ in how much of the handling the machine does: the HF-8288 is an automatic line 5.55 m long and 1,200 kg, the HF-808 a semi-automatic station 3.2 m long and 600 kg.

Is an automatic rigid box line faster?

Less than most buyers expect. The HF-5040 is rated at 18–25 pieces per minute and a line ending in an HF-450 at 15–20. A modular line with an HF-1050 positions at up to 30 sheets per minute, but the forming machine after it still wraps 15–20, so the line speed does not change.

What automation changes is consistency and handling. Every shell is placed to ±0.1 mm whoever is on shift, and the hand positioning station between gluing and forming disappears. Speed comes from adding forming capacity, not from automating the positioning.

Changeover and setup

• HF-450: the box size is entered on the touch screen and the forming parameters are set automatically.
• HF-500: electronic plus manual adjustment, and one machine covers a wide range of sizes.
• HF-5040: one control system sets the box size for every step, with a servo and pneumatic wrapping unit adjusted from the screen.
• HF-5040 loading: it carries a 1000 mm stack of board and a 500 mm stack of paper.

Upgrading a semi-automatic line in stages

1. 01

   Start with the semi-automatic set

   HF-1200, HF-500, HF-850A and HF-450. Choose the servo version of the HF-850A if automation is likely later.

2. 02

   Automate the positioning

   Add a Yamaha robot to the servo HF-850A to turn it into an automatic positioning machine, or replace the gluing machine with an HF-1050, which glues and positions to ±0.1 mm.

3. 03

   Add forming capacity

   Forming is the slowest step at 15–20 pcs/min, so a second forming machine is what raises the output of the line.

How to choose between automatic and semi-automatic

• Many sizes, short runs: semi-automatic machines change over with simple adjustments and suit a varied order book.
• Printed boxes with tight registration: camera positioning holds ±0.1 mm on every piece; hand positioning depends on the operator.
• Small boxes and thick board: the HF-450 forms down to 45 × 45 × 15 mm in board up to 4 mm. The HF-5040 starts at 65 × 65 × 20 mm and takes 1–3 mm board.
• Floor space: the HF-5040 needs about 8.2 × 4.2 m. An HF-450 is 1.4 × 1.1 m, plus the gluing machine in front of it.
• Power: the HF-5040 needs 380 V three-phase at 15 kW. The HF-40, HF-500 and HF-450 run on 220 V.
