The focus is on the efficiency of models such as DSF-6000, DSF-2200, DBM-700, DBM-350, and DBM-150, as well as a comparison between systems with towers and feeders. The impact of the number of sheets, type of feeding system, and format limitations on speed and production efficiency is examined.
1. Comparison of Performance of Key Models
DSF-6000 vs. DSF-2200 (with DBM-700)
Model | Sheet Speed | Speed with DBM-700 | Efficiency |
---|---|---|---|
DSF-6000 | 3x faster than DSF-2200 | Double speed for 5+ sheets | High efficiency |
DSF-2200 | Normal | Limited | Lower efficiency |
The DSF-6000 is three times faster than the DSF-2200 in terms of sheet feeding speed. However, when combined with DBM-700, its productivity doubles only for sets of 5 or more sheets. The main limitation arises from the processing capacity of DBM-700, which creates a bottleneck.
2. Performance of Tower-Based Machines (DBM-700, DBM-350, DBM-150)
DBM-700 with Towers
Number of Sheets | A5 SEF | LTR LEF | LTR SEF | A4 SEF | LGL | B4 | A3 | LDR | SRA3 | Maximum |
---|---|---|---|---|---|---|---|---|---|---|
2-30 sheets | 5202 | 5150 | 5120 | 4812 | 4736 | 4500 | 4466 | 4260 | 4215 | 3603 |
- Performance: Maintains constant speed regardless of the number of sheets in the set.
- Key Feature: The tower system feeds all sheets simultaneously, making it extremely efficient for large formats and volumes.
- Limitations: Slower speeds for larger formats such as SRA3 and maximum size (610 mm).
DBM-350 with Towers
Number of Sheets | A5 SEF | LTR LEF | LTR SEF | A4 SEF | LGL | B4 | A3 | LDR | SRA3 | Maximum |
---|---|---|---|---|---|---|---|---|---|---|
2-20 sheets | 3000 | 3000 | 3000 | 3000 | 3000 | 2893 | 2877 | 2778 | 2758 | 2711 |
- Performance: Maintains a stable speed of 3000 sets/hour for smaller formats (A5, LTR, A4).
- Key Feature: Exceptionally stable performance for up to 20 sheets per set.
- Limitations: Lower speed for larger formats such as B4, A3, SRA3, and LDR.
DBM-150 with Towers
- Performance: 2400 sets/hour.
- Application: Suitable for small to medium production volumes.
- Key Advantages: Consistent performance regardless of the number of sheets.
3. Comparison Between Tower and Feeder Systems
System | Feeding Process | Speed | Performance | Maintenance |
---|---|---|---|---|
Towers | Feeds all sheets simultaneously | Constant speed | High efficiency | Low maintenance |
Feeders | Feeds sheet by sheet | Speed decreases with more sheets | Reduced for larger sets | Higher maintenance |
4. Key Takeaways
-
DBM-700 is the Most Productive Machine
- Maintains 5200 sets/hour for formats up to A4, even with 30 sheets per set.
-
DBM-350 and DBM-150 Offer Effective Solutions for Specific Needs
- DBM-350: Lower speed for larger formats but stable at 3000 sets/hour for smaller formats.
- DBM-150: Designed for small volumes and delivers 2400 sets/hour.
-
Tower Systems Outperform Feeders
- Higher productivity under all conditions.
- Constant speed for sets from 2 to 30 sheets.
- Less wear and lower maintenance costs.
Conclusion
This comparison demonstrates that tower systems significantly outperform feeders in terms of productivity, speed, and reliability. DBM-700 stands out as the leading machine for high volumes, while DBM-350 and DBM-150 are excellent choices for medium and small production needs. The tower system ensures simultaneous feeding of all sheets, maintaining constant speed and minimal wear on the machine.
