View Patent ↗A coiler device for winding a strip of cushioning material into a coil is disclosed. The coiler device includes a working plate, at least two winding pins and a driving mechanism. The working plate has a working surface, a rotation axis and at least two holes away from the rotation axis. The at least two winding pins are disposed through the at least two holes and protruding out of the working surface respectively when winding the strip. The driving mechanism is configured to rotate the working plate, wherein the at least two winding pins are retractable from the working plate through the at least two holes respectively.
1 . A coiler device for winding a strip of cushioning material into a coil, comprising:
a working plate having a working surface, a rotation axis and one or more holes through the working surface;
at least two winding pins disposed through the one or more holes of the working plate and protruding out of the working surface when winding the strip;
a rotational driven member coupled to the working plate, wherein the rotational driven member is configured to automatically rotate the working plate to wind the strip into the coil; and
a linear driven member coupled to the at least two winding pins, wherein the linear driven member is configured to automatically retract the at least two winding pins, wherein the at least two winding pins are retractable from the working surface through the one or more holes of the working plate to release the coil.
2 . The coiler device as claimed in claim 1 , further comprising:
a frame having a rotation axis as that of the working plate, wherein the at least two winding pins are attached to the frame; and
wherein the linear driven member is coupled to the frame to guide the frame along a direction parallel to the rotation axis.
3 . The coiler device as claimed in claim 2 , wherein the frame is disposed near one side of the working plate opposite to the working surface.
4 . The coiler device as claimed in claim 2 , wherein the linear driven member includes a trapezoidal lead screw or an actuator shaft disposed along the rotation axis, and the frame is rotatable around the trapezoidal lead screw or the actuator shaft.
5 . The coiler device as claimed in claim 4 , wherein a bearing is disposed between the frame and the trapezoidal lead screw or the actuator shaft.
6 . The coiler device as claimed in claim 4 , wherein the linear driven member is connected to a transmission.
7 . The coiler device as claimed in claim 1 , wherein the working plate is facing upward.
8 . The coiler device as claimed in claim 7 , wherein an angle of a predetermined degree occurs between the working plate and a horizontal level.
9 . The coiler device as claimed in claim 1 , wherein at least one of the at least two winding pins is bendable.
10 . The coiler device as claimed in claim 1 , wherein the at least two winding pins are made of flexible materials or have hinging portions protruding out of the working surface respectively.
11 . The coiler device as claimed in claim 1 , wherein a detection sensor is disposed on the working surface, and the detection sensor is configured to detect whether the strip of the cushioning material is in a winding process.
12 . A coiler device for winding a strip of cushioning material into a coil, comprising:
a main body;
a working plate having a working surface and a rotation axis;
at least two winding pins protruding out of the working surface when winding the strip;
a rotational driven member coupled to the working plate, wherein the rotational driven member is configured to automatically rotate the working plate with respect to the rotation axis to wind the strip into the coil; and
a linear driven member coupled to the at least two winding pins, wherein the linear driven member is configured to automatically retract at least one of the two winding pins into the main body to release the coil.
13 . The coiler device as claimed in claim 12 , wherein:
the working plate includes at least one hole away from the rotation axis; and
the at least one of the two winding pins is disposed through the at least one hole to be retractable into the main body through the at least one hole.
14 . The coiler device as claimed in claim 12 , wherein the working plate does not rotate when the at least one of the two winding pins is retracted into the main body.
15 . The coiler device as claimed in claim 12 , further comprising a visual scale disposed on the working surface for indicating a diameter of the coil of the cushioning material, wherein the rotational driven member stops rotating the working plate when the coil of the cushioning material is winded to a set diameter.
16 . The coiler device as claimed in claim 12 , further comprising at least one bearing or track guider member, wherein:
the working plate has a U or V shaped profile at an outer edge thereof; and the at least one bearing or track guider member is guided by the U or V shaped profile so that the working plate is kept from radial and axial movements.
17 . A coiler device for winding a strip of cushioning material into a coil, comprising:
a working plate having a working surface and a rotation axis; and
at least two winding pins disposed away from the rotation axis and protruding out of the working surface when winding the strip, wherein at least one of the at least two winding pins are at least partially formed from a flexible material or hinged adjacent to the working plate to allow bending or pivotable movement of the at least one of the at least two winding pins.
18 . The coiler device as claimed in claim 17 , wherein the at least one of the at least two winding pins is made of the flexible material.
19 . The coiler device as claimed in claim 17 , wherein the working plate includes at least two holes away from the rotation axis, and the at least two winding pins are disposed through the at least two holes respectively and protruding out of the working surface when winding the strip.
20 . The coiler device as claimed in claim 19 , wherein the at least two winding pins are disposed on a frame having a rotation axis the same as that of the working plate.
21 . The coiler device as claimed in claim 20 , further comprising:
a linear drive member coupled to the frame to guide the frame along a direction parallel to the rotation axis to retract the at least two winding pins from the working surface.
