ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a material picking device and a forming device for an automatic circulating carton opening machine, particularly to one having a revolving unit to swing around to continuously and quickly picking material carton boards from a material feed device of the machine and carrying them onto the forming guide plate to form the material into a carton shape.
As for cartons packed automatically, opening, forming and adhering operations are all performed by an automatic machine, no longer manually by workers. So, various carton machines have been offered by makers, but generally having the same operating method to sending out carton material boards by a material feed device and moved into a forming device for from it into a carton, and one example is shown in FIG.
9
.
The carton machine shown in
FIG. 9
has a forming device
10
to form a carton material board into a carton. The device
10
mainly has a first sucking disc
101
and a second sucking disc
103
pivotally connected to a connecting rod unit
102
. A crank
104
is provided under the connecting rod unit
102
and pivotally connected to an output shaft of an oil pressure cylinder
105
. When a carton material board is moved onto the first sucking disc
101
, it is sucked to the first sucking disc
101
, and then the oil pressure cylinder
103
immediately operates to carry the connecting rod units
102
move down and let the second sucking disc
103
move down in parallel to suck a carton material board. When the oil pressure cylinder
105
operates again, carrying the second sucking disc
103
move up in parallel, forming a flat carton material board into a carton shape.
The forming device just described above used the oil pressure cylinder
105
to move the second sucking disc
103
up and down for picking material and forming into a carton. But the output shaft of the oil pressure cylinder
105
needs not a little time in moving out and in, so therefore carton forming is slow, making up a disadvantage of the machine.
SUMMARY OF THE INVENTION
The main objective of the invention is to offer a material picking device and a forming device for an automatic circulating carton opening machine. The two devices are fixed on an intermediate portion of the table of the machine, and the material picking device includes a revolving unit and the forming device includes a forming guide plate. The revolving unit includes an elongate swinging arm, two rotating gear units fixed at two ends of the swinging arm. Each gear unit has a belt wheel at the outermost end connected to two parallel arms fixed with two material sucking discs. The forming guide plate is positioned on an intermediate portion of the table in front of the revolving unit and at one side of the moving route of the swinging arm. So, the two parallel arms are moved horizontally by operation of the rotating gear units of the swinging arm, and then the sucking discs continuously and alternately pick a carton material board from the material feed device of the machine, carrying the carton material board to let the board lie on the forming guide plate to be formed into a carton shape. Thus the two sucking discs alternately and continuously pick a carton material board, greatly increase operating speed of the automatic circulating carton opening machine.
