MATERIAL CONVEYING SYSTEM WITHOUT DUST RISING
Abstract
A material conveying system without dust rising, having a
plurality of trays; a transmission mechanism, for carrying the
trays and transmitting the trays in motion; and a controller, for
controlling the transmission mechanism, is characterized in that
the material conveying system without dust rising further has a

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a material conveying system
and, in particular, to a material conveying system without dust
rising, having the transmission shaft and the chain belt thereof
immersed in a liquid so as to keep the material from being
contaminated by abraded dust.
[0003] 2. Descriptions of the Related Art
[0004] Most of the traditional material conveying systems have an
effect of moving the material by a motor that is linked to a
transmission shaft, which in turns drives a chain belt with the
chain belt linked to trays or a transport belt. However, the
mechanical structure of the material conveying system, which is
constituted by the transmission shaft and the chain belt, is bound
to have abrasion as a result of long-term use. The abraded dust
will float in the space and probably contaminate the material
conveyed by the system. Therefore, contamination may be made in the
transportation of material that requires high precision and does
not allow dust contamination, to decrease the yield or to cause
flaws. Therefore, in current operating environments in dust-free
rooms, transport-belt material conveying systems are used seldom
for the sake of reducing the contamination of dust. However, for
the purpose for orientating to the automation of production chain,
there is an urgent need for a material conveying system without
dust rising, in which the contamination of dust occurs
unlikely.
SUMMARY OF THE INVENTION
[0005] The present invention relates to a material conveying system
without dust rising, for the objective to improve the traditional
material conveying system, wherein the material conveying system
without dust rising has the transmission shaft and the chain belt
thereof immersed in a liquid so as for the abraded dust resulting
from long-term use of the transmission shaft and the chain belt to
be contained in the liquid, but not to float in the space, and
thereby for the material to be kept from being contaminated by
abraded dust.
[0006] To achieve the objective described above, the material
conveying system without dust rising has a plurality of trays; a
transmission mechanism, for carrying the trays and transmitting the
trays in motion; and a controller, for controlling the transmission
mechanism, the system characterized in that the material conveying
system without dust rising further has a tank, which carries a
liquid, where the transmission mechanism is immersed in the liquid
so that the dust resulting from abrasion of the transmission
mechanism cannot float in the air.
[0007] Preferably, the liquid has low volatility, low
combustibility, no toxicity, and low corrosiveness, for more safety
and for preventing the mechanism that is immersed in the liquid
from being corroded.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] FIG. 1 is a top view of a first embodiment of the material
conveying system without dust rising according to the present
invention.
[0009] FIG. 2 is a cross sectional view of a second embodiment of
the material conveying system without dust rising according to the
present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0010] The present invention will be described fully with reference
to the accompanying drawings provided with preferred embodiments of
the invention, but it will be understood, prior to this
description, that modifications of the invention described herein
may be made by those skilled in the art while the functions of the
invention can be achieved. Therefore, it will be understood that
the following description is a general disclosure to those skilled
in the art and the content thereof is not intended to limit the
present invention.
[0011] Refer to FIGS. 1 and 2, which show a top view and a cross
sectional view, respectively, of an embodiment of the material
conveying system without dust rising according to the present
invention. In this preferred embodiment, the material conveying
system without dust rising according to the present invention
comprises: a controller 1, electrically connected to a motor 2, for
controlling the switch and rotation rate of the motor 2; a motor 2,
electrically connected to the controller 1 and linked to a
transmission shaft 3, for supplying power to the material conveying
system without dust rising; a transmission shaft 3, linked to the
motor 2 by one end and to a chain belt 4 by another one end, for
transmitting the chain belt 4; a chain belt 4, driven by the
transmission shaft 3, having a plurality of contacts disposed
thereon, each of which is respectively connected to one of a
plurality of tray holders 5; a plurality of tray holders 5, each of
which is connected to the chain belt 4 by one end and to one of a
plurality of trays 6 by the other end; a plurality of trays 6, each
of which has the bottom end thereof connected to one of the tray
holders 5, and having the face thereof for carrying material 9 to
convey; a tank 7, filled with a liquid 8, in which the mechanical
structure constituted by the transmission shaft 3, the chain belt 4
and the tray holders 5 is immersed. In transportation of material,
the material 9 may be placed on the trays 6 so as to be
transported.
[0012] According to this preferred embodiment of the present
invention, in the transportation of the material 9 by the conveying
system, the mechanical structure constituted by the transmission
shaft 3, the chain belt 4 and the tray holders 5 is immersed in the
liquid 8 so that the dust resulting from abrasion between those
members is kept in the liquid 8 but not floats in the air. Thus,
reduction of the concentration of dust in the air may be
facilitated. The material conveying system according to the present
invention is especially applicable, for example, to clean rooms or
to production lines strictly requiring the air quality. In
preferred embodiments, the liquid 8 in the tank 7 is preferably a
liquid having low volatility, low combustibility, no toxicity, and
low corrosiveness, such as silicone oil.
