BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synchronization system and method of a press apparatus, and more particularly, to a synchronization system and method of a press apparatus that improves productivity by making the press cycle period and speed of each press apparatus equal in a process line composed of a plurality of press apparatuses And methods.
Generally, a press apparatus is a device for performing plastic working such as bending, throttling, and shearing of a material by using a mold, and is composed of a table on which a material is placed, a slide reciprocating linearly, and a motor for driving the slide.
Particularly, a plurality of press apparatuses arranged in a process in which a plurality of sintering processes are successively performed on one material are provided in the respective press cycles. That is, since the cycle of the reciprocating slide is different in order to perform the plastic working of the material, after the process is completed in one press apparatus, the material is transferred to the next press apparatus and the material must be supplied in accordance with the cycle of the press apparatus in order to perform the process. There is a problem in that a waiting time is required between the processes and thus the productivity is lowered.
In order to solve such a problem, Korean Patent Registration No. 10-1658899 discloses, as shown in FIG. 1, a press for pressing a material and a feeder for feeding the material to the press at a pitch in accordance with the operation of the press. And a tension unit for applying a back tension to the material in a direction opposite to the conveying direction of the feeder at the immediately preceding end of the press. In this case, the material is fed in accordance with the cycle of one press apparatus It is impossible to solve the above-mentioned problem in a process in which a plurality of press apparatuses are provided so as to perform continuous press work.
In order to solve the above-mentioned problems, the present invention provides a press apparatus for synchronizing a press cycle of each press apparatus in a process line composed of a plurality of press apparatuses to minimize a waiting time occurring during a process through a continuous press apparatus Synchronization system and method.
There is a configuration in which a press device body composed of a wheel rotated by a motor, a belt, gear, or the like, a slide reciprocating vertically through the rotation of the wheel, and a clutch provided on one side of the wheel, A reference press device composed of an inverter connected to the motor, an encoder provided at one side of the rotary shaft, and a synchronous controller connected to the inverter and the encoder to exchange signals, Wherein the reference press device and the synchronous controller of the slave press device are connected to each other by wire or wireless, or are integrated with each other.
According to another aspect of the present invention, there is provided a method of controlling a press apparatus, comprising: a first step of setting a SPM of a reference press apparatus using a synchronization system of the press apparatus configured as described above; A second step of generating drive pulses in the inverter of the press apparatus and transmitting the generated drive pulses to the synchronous controller; and a second step of driving the reference press apparatus by the drive pulses and generating angular pulses in the encoders of the reference press apparatus, And the SPM of the dependent pressing apparatus is set through a synchronous controller. When the SPM set in the fourth step is equal to or greater than 0, a drive pulse is generated in the inverter of the dependent press apparatus, And a second step of receiving the reference press apparatus received in the second step, And the drive pulse of the inverter of the subsidiary press apparatus synchronized in the sixth step is synchronized with the drive pulse of the inverter of the subsidiary press apparatus synchronized in the sixth step, A seventh step of driving the slave press device, generating an angle pulse at the encoder of the slave press device, and transmitting the generated angle pulse to the synchronization controller, and transmitting the angle pulse of the reference press device encoder transmitted to the synchronization controller in the third and seventh steps And an eighth step of comparing and synchronizing the angular pulses of the relative press machine encoder with each other.
According to another aspect of the present invention, in the eighth step, when the angle pulse of the reference press apparatus encoder is larger than the angle pulse of the dependent press apparatus encoder, the synchronous controller increases the inverter drive pulse of the slave press apparatus, If the angular pulse of the encoder is less than the angle of the dependent press machine encoder, the synchronization controller lowers the inverter drive pulse of the dependent press machine, and if the angular pulse of the reference press machine encoder is equal to the angle pulse of the dependent press machine encoder, And the drive pulse of the inverter of the dependent press apparatus is maintained.
As described above, according to the present invention, a synchronization system and method of a press apparatus includes a plurality of press apparatuses to synchronize slide cycles of respective press apparatuses in a process in which a continuous press operation is performed, thereby reducing standby time between press processes, There is an effect of improvement.
