## Background
BACKGROUND
1. Field of the Invention
The present invention relates to removal devices, and particularly to a removal device which can efficiently remove a package from a component band.
2. General Background
Conventionally, there are a lot of electronic components arranged on a circuit board to form a circuit with a certain function, such as capacitors, resistors, and inductors. As showing in FIG. 1, a component band 1 fixed with above mentioning electronic components often is used during the assembly of the circuit board. The component band 1 includes a carrier band 2, and a package 5 attached on the carrier band 2. The carrier band 1 defines a lot of dents 3, and a lot of apertures 6 therein. Each dent 3 accommodates with an electronic component 4 therein. The package 5 is configured to prevent the components 4 from damaging. Before assembly, the package 5 must be removed by some tools to expose the components 4 on the carrier band 2 for easily being picked up. Japan Patent No. 9-64586 discloses a package removal device. The package removal device includes a conveyor band, and a collecting wheel. The component band moves through the package removal device, and the package winds around the collecting reel to be stripped from the component band. However, when many of the packages wind around the collected reel, the machine must stop to take down the collecting wheel for cleaning the packages. This is inconvenient and costly during the whole assembly process.
What is desired, therefore, is a package removal device which can efficiently remove a package from a component band.
SUMMARY
An exemplary of the package removal device is for removing a package from a component band to expose a carrier band. The package removal device includes a stand, a first scrolling unit includes a first gear, and a second scrolling unit includes a second gear. The stand includes a platform with an import end and an export end. The export end includes a locating gear mounted thereon, a first exit, and a second exit. The component band is separated into the package and the carrier band in the export end. The first gear meshes with the second gear to output the package from the first exit. The locating gear engages the carrier band to output the carrier band from the second exit.

A grading hole 89 is defined in a central portion of the second gear 85. A through hole 871 is defined in the second one-way bearing 87. The urging plate 88 includes a hollow sleeve 884 extending from an end thereof, and an aperture 882 and a through hole 886 defined therein.
Referring also to FIGS. 3 and 4, the first and second scrolling units are separately assembled to the stand 10.
The screw 40 is extended through the first mounting hole 32 of the main mounting board 30, the central hole 382 of the driving plate 38, the central hole 362 of the pressing plate 36 in turn to engage in the first stud 51. The hollow sleeve 341 of the relaying member 34 is extended through the hollow sleeve 563 of the swing plate 56, the through hole 531 of the first one-way bearing 53 to engage in the grading hole 55 of the first gear 52. The resilient member 58 is extended through the bushing 60. Two free ends of the resilient member 58 engage in the aperture 564 of the swing plate 56 and the slot 389 of the driving plate 38 respectively. Two free ends of the resilient member 48 engage in the aperture 364 of the pressing plate 36 and aperture 386 of the driving plate 38 respectively. Two free ends of the resilient member 39 engage in the slot 389 of the driving plate 38 and the rod 15 of the stand 10 respectively. The screw 95 is extended through the through hole 942 of the crank bar 94 to engage in the through hole 385 of the driving plate 38.
The second one-way bearing 87 engages in the grading hole 89 of the second gear 85. The screw 41 is extended through the through hole 886 of the urging plate 88, the gasket 47, and the through hole 871 of the second one-way bearing 87 to engage in the second stud 86. The third stud 92 engages in the hollow sleeve 884 of the urging plate 88. The screw 45 is extended through the second mounting hole 44 of the first mounting board 42, and the torsion spring 90 to engage in the third stud 92. Two free fingers of the torsion spring 90 are engaged in the aperture 882 of the urging plate 88 and the aperture 43 of the first mounting board 42 (see FIG. 7).
In work, the component band 1 is feed into the package removal device via the entry 141 of the import end 14a. The component band 1 contacts the post 13 and creeps along the platform 12 to the export end 14b. The component band 1 moves below the bridge 20 and is divided into the package 5 and the carrier band 2. The carrier band 2 moves on and passes through the second exit 22, with the apertures 6 engaging with teeth of the locating gear l8. The package 5 frictionally passes the blade 23 and is propelled in a different direction with the carrier band 2 out of the first exit 24. The package 5 moves along a lower circumference of the pole 28, an upper circumference of the spindle 11, and a lower circumference of the roller 368 of the pressing plate 36 to climb to the first gear 52. The second gear 85 is pushed away from the first gear 52, and the torsion spring 90 is twisted. When the package 5 moves on a top circumference of the first gear 52, the second gear 85 is released to mesh with the first gear 52. The package 5 moves between the first gear 52 and the second gear 85 and further moves into the ditch 46.
Referring also to FIGS. 5 and 6, a force is applied to the contact side 387 of the driving plate 38 to rotate the driving plate 38 clockwise. The pressing plate 36, the bushing 60, and the swing plate 56 are accordingly rotated clockwise. The second gear 85 is moved to clockwise rotate by the resilient member 48. The crank bar 94 is accordingly moved to rotate the leaf 17. The slider 21 moves away the second exit 22, with the pin 172 of the leaf 17 sliding in the channel 212 of the slider 21. The one-way ratchet 16 and the component band 1 keep still. The package 5 is accordingly stretched by the roller 368 of the pressing plate 36 and is separated from the component band 1 by the blade 23. Thus, the electronic components 4 of the component band 1 are exposed on the carrier band 2.
Referring also to FIGS. 3, 4 and 7, when the force is released, the resilient member 39 is restored to move the driving plate 38 back, the resilient member 48 is restored to move the pressing plate 36 back, and the resilient member 58 is restored to move the swing plate 56 back. Accordingly, the first gear 52 rotates anticlockwise to mesh with the second gear 85. The package 5 is moved along the ditch 46 via the first gear 52 and the second gear 85. The package 5 falls into a collecting box 8 passing along outer surfaces of the import end 14a. At the same time, the crank bar 94, the slider 21, and the leaf 17 move back to their respective original positions. The locating gear 18 accordingly rotates back to move the carrier band 2 pass the second exit 22.
With the recycle of the above operations, the package 5 is moved into the stand 10 from the import end 14a and the carrier band 2 is attained out of the export end 14b continuously. Without any stops, the package 5 is removed from the component band 1 during the work. The efficiency is increased.
The first gear 52 and the second gear 85 can be replaced by other elements, such as a pair of engaging wheels with enough frictions therebetween. The first one-way bearing 53 and the second one-way bearing 87 also can respectively be replaced by another unidirectional clutch member, such as a ratchet.
It is believed that the present embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the example hereinbefore described merely being a preferred or exemplary embodiment of the invention.
