摘要:
The present invention concerns a device for control of the traction force exercised upon a conveyor, for example in a press, which includes at least one measuring device (1) of the traction force. The device further includes control means (2,3) that include a device for conditioning (2) the recorded signal from the measuring device (1), and a data management and processing device (3) which, based on specific software, makes a comparison between the recorded signal and some preset comparison parameters, which include various ranges of comparison of force values programmed in function of each moment of the cycle and speed of the press, with each range being linked to different actions, devices and operations of the press.
摘要:
The transmission mechanism comprises a lever (12) which can rotate around an eccentric shaft (11) of a rotating disk-crank (10). The lever (12) is guided in its movement by cam means (15a) and acts upon an arm (19) which is attached for joint rotation to an output shaft (3). Advantageously the disk-crank (10) is driven through a connecting rod (8) from another disk-crank (1) which can rotate around a shaft which is different from that of the first disk-crank (10). It doesn't require adjustment or setting up and it has a low cost. The transport device has on the output shaft the wheels for drawing chains with transporting bars provided with clamps for the sheets.
摘要:
It includes at least one measuring device (2) of pressing force, and it is characterised in that it includes control means (3,4) and means for interaction (5,6) with the user, said control means including a device for processing (3) the recorded signal from the measuring device (2), and a device for data management and processing (4) which, based on specific software, makes a comparison between the recorded signal and some preset regulating parameters, obtaining an automatic correction of the regulation of the pressing force until an optimum force value is achieved.
摘要:
The clutch (1,21) transmits a movement generated by a drive shaft (3,23) to an output shaft (2,22), and the circuit includes at least one proportional-pressure valve (5,12,25) for the fluid and/or gas supplied to a clutch chamber (1,21), actuated in accordance with pressure-control signals (6,13,26) processed by a microprocessor (7,27), and means (4,24) for treating the fluid and/or gas supplied to said proportional pressure valve (5,12,25). It is characterised in that the circuit includes at least one fluid and/or gas proportional-flow valve (9,15,29) actuated in accordance with flow-control signals (11,16,31) processed by a microprocessor (7,27), at least one pressure tank (8,14,28) situated at the outlet from said at least one proportional-pressure valve (5,12,25), and a valve (10,30) connected to the clutch chamber (1,21) to activate filling or draining of the fluid and/or gas, such that the circuit provides at all times the necessary pressure (P) inside the clutch (1,21) to transmit the torque required in accordance with the movement of the output shaft (2,22).
摘要:
It comprises a main shaft (1) attached to a transmission element (2) that imparts an intermittent rotary movement to the main shaft (1), a positioning plate (8) attached to the main shaft (1), a drive sprocket (9) attached to a transmission shaft (4) of the sheet conveyor device, and a coupling device (13,14,19,20) able to transmit the movement of the positioning plate (8) to the drive sprocket (9). It is characterised in that the coupling device is a hydraulic and/or pneumatic proportional clutch which includes a pressure chamber (13) fed with a fluid and/or gas at a constantly adjustable pressure (P) by means of a hydraulic and/or pneumatic exterior circuit, a piston (14) that moves in response to said pressure (P), and means of engaging or disengaging the clutch (19,20) associated with the piston (14), the positioning plate (8) and the drive sprocket (9), in such a way that the clutch permits at all times delivery of the torque required in function of the main shaft's (1) movement.
