- a belt conveyor is suitable for long-distance conveyance at a low price, but has a lower conveying speed than other types in which positioning accuracy of conveyed objects is low.
- the belt conveyor requires a large installation space that is proportional to the transport distance.
- the screw-type feeder improves the transfer accuracy by using a polished ball screw, and also enables transfer at medium and high speeds. Nevertheless, in the case of using an expensive polished ball screw, it becomes a cost-push factor, which makes the apparatus expensive.
- the screw feeder is not space-saving, but also has a short transport distance, which makes long-distance transport such as a belt conveyor difficult.
- the cylinder type feeder Similar to the screw type feeder, the cylinder type feeder has problems such as difficulty in long-distance conveyance and high price, and has not been achieved as compact as space-saving type. Above all, the practical difficulty of the cylinder type feeder is that it is difficult to change the transfer stroke arbitrarily.
- a timing belt type feeder is lower in cost than a screw type feeder using a polished ball screw.
- the transport distance of the timing belt can be set longer than that of the screw feeder / cylinder feeder.However, there are restrictions on the production and loosening of the belt may occur. Is difficult. In other words, the timing belt type feeder does not become as long as the belt conveyor, but the transport distance is shortened accordingly. Robots, on the other hand, are much more accurate and sophisticated, but too expensive. Also, it is suitable for continuous transport over long distances.
- an object of the present invention is positioning accuracy 'long distance transfer' remote transfer ⁇ controllability, high precision feed, high speed feed, low price ⁇ simple configuration ⁇ space saving ⁇ light weight ⁇ Particle generation countermeasures ⁇
