Abstract
A feeding device includes a plurality of driving modules, a plurality of feeding modules and a plurality of couplers. Each driving module has a driving shaft pivotally mounted on a housing and driven by a power module to be rotated about an axis. Each feeding module includes a pivoting shaft substantially coaxial with the driving shaft, a suspending unit journalled on the pivoting shaft to be pivotable and having a bearing portion which is disposed to be biased downwardly by a spring member, a driven shaft mounted rotatably on the bearing portion, and a feeding roller driven by the driven shaft. Each coupler includes a transmitting shaft having two ends connected to the driving shaft and driven shaft by universal joints, respectively.
Claims8
A feeding device comprising:
- a housing;
- a power module;
- a plurality of driving modules, each including a driving shaft which is pivotally mounted on said housing and driven by said power module to be rotated about an axis;
- a plurality of feeding modules, each including a pivoting shaft which is mounted on said housing and which extends along the axis to be substantially coaxial with said driving shaft of a respective one of said driving modules, a suspending unit which is journalled on said pivoting shaft to be pivotable about the axis and which has a bearing portion offset from and parallel to the axis, a spring member which is disposed to bias said bearing portion downwardly, a driven shaft which is mounted on said bearing portion to be biased by a biasing action of said spring member and which is rotatable relative to said bearing portion, and a feeding roller which is mounted on and driven by said driven shaft;
- and
- a plurality of couplers, each including a transmitting shaft, a first universal joint interconnecting an end of said transmitting shaft and said driving shaft of a respective one of said feeding modules, and a second universal joint interconnecting an opposite end of said transmitting shaft and said driven shaft of the respective one of said feeding modules.
