If, when the first workpiece is no longer needed for the first and third stations a411, a413, the support table a4 is moved away from the discharge opening with the transfer mechanism a 5. For example, in fig. 1, the supporting table a4 and the driving plate a31 move from front to back as a whole, and the driving plate a31 and the supporting table a4 avoid the discharge port as a whole, and at this time, although the first workpiece is no longer added into the vibrating bin a11 of the feeding mechanism, a small amount of the first workpiece may remain in the feeding guide rail a13 of the feeding mechanism, and the small amount of the first workpiece directly falls into the discharge bin for recycling. Similarly, when the second workpiece is no longer needed in the second station a412 and the fourth station a414, the supporting table a4 and the driving plate a31 are removed, and all the second workpieces left on the feeding mechanism are dropped into the receiving bin a7 through the material conveying guide rail a13 for recycling. Optionally, the number of the receiving bins a7 corresponds to the number of the discharge ports one by one and is located right below the discharge ports.
The feeding process of the switchable feeding device of this embodiment is as follows:
when a first workpiece needs to be conveyed to the first station a411 and the third station a413, the position of the supporting table a4 is changed under the driving of the transfer mechanism a5, for example, the supporting table a411 and the third station a413 move forward in fig. 1, so that the first station a411 and the third station a413 are respectively butted and communicated with the outlets of the first material conveying guide rail and the second material conveying guide rail, the supporting table a4 is in a non-material blocking state, and the lifting mechanism does not work; starting the feeding mechanism, and respectively conveying first workpieces to a first station a411 and a third station a413 through outlets of a first conveying guide rail and a second conveying guide rail of the feeding mechanism; when two first workpieces respectively slide on the first station a411 and the third station a413, the optical fiber sensor detects the first workpiece on the stations, a signal is sent to the controller, the controller controls the vacuum pump to be started according to the signal, so that the adsorption surface of the suction cup a6 forms negative pressure, and the first workpieces are adsorbed on the respective stations.
At this time, the transfer mechanism a5 drives the supporting platform a4 to move away from the discharge port, for example, to move backwards in fig. 1, the supporting platform a4 moves to the next working procedure, and the material taking mechanism takes away the first workpiece; the transfer mechanism a5 drives the supporting platform a4 to move forward, so that the first station a411 and the third station a413 are in butt joint communication with the outlets of the first material conveying guide rail and the second material conveying guide rail respectively, the next first workpiece just starts to slide on the first station a411 and the third station a413, and so on, and the first workpiece is continuously conveyed to the first station a411 and the third station a 413.
Or the lifting cylinder drives the supporting platform a4 to move upwards integrally, so that the side wall surfaces of the supporting platform a4 facing the outlets of the first material conveying guide rail and the second material conveying guide rail are blocked on the outlets of the first material conveying guide rail and the second material conveying guide rail; then the transfer mechanism a5 drives the supporting platform a4 to move away from the discharge port, for example, move backwards in fig. 1, the supporting platform a4 moves to the next working procedure, and the material taking mechanism takes away the first workpiece; the transfer mechanism a5 drives the supporting platform a4 to move forward, and the side wall surface of the supporting platform is always slidably stopped on the outlets of the first material conveying guide rail and the second material conveying guide rail in the process of driving the supporting platform to move by the transfer mechanism; then the lifting mechanism makes descending movement, so that the first station and the third station are reset to the positions where the first station and the third station are in butt joint communication with the outlets of the first material conveying guide rail and the second material conveying guide rail respectively, the first workpiece is received again, and by analogy, the first workpiece is continuously conveyed to the first station a411 and the third station a 413.
After the first workpiece is conveyed, the stations need to be switched, two feeding mechanisms are needed to respectively convey the second workpiece to the second station a412 and the fourth station a414, at this time, the lifting cylinder drives the supporting table a4 to integrally move upwards, so that the side wall surfaces of the supporting table a4 facing the first material conveying guide rail and the second material conveying guide rail are blocked on the outlets of the first material conveying guide rail and the second material conveying guide rail, the workpiece does not slide from the outlets of the first material conveying guide rail and the second material conveying guide rail, and the supporting table a4 is in a material blocking state; the second workpiece is prevented from scattering on the supporting table a4 or sliding on the first station a411 and the third station a 413; meanwhile, the transfer mechanism a5 drives the support table a4 to move forward (in front in fig. 1), so that the second station a412 and the fourth station a414 slide to positions above the outlets of the first material conveying guide rail and the second material conveying guide rail, and during the sliding process of the support table along with the transfer mechanism, the side wall of the support table a4 slidably blocks the outlets of the first material conveying guide rail and the second material conveying guide rail, and the support table a4 is still in a blocking state; then, the lifting mechanism a2 is started, the lifting mechanism a2 drives the supporting table a4 to move downwards, the second station a412 and the fourth station a414 descend and are respectively communicated with the outlets of the first material conveying guide rail and the second material conveying guide rail in a butt joint mode, the supporting table a4 is in a non-material blocking state, and the lifting mechanism a2 stops working; the outlets of the first material conveying guide rail and the second material conveying guide rail can respectively convey second workpieces to the second station a412 and the fourth station a414, and the conveying process of the second workpieces is the same as that of the first workpieces, so that no workpieces are scattered at the outlets of the first material conveying guide rail and the second material conveying guide rail in the switching process of different stations, and the confusion phenomenon that the same station receives different batches of workpieces is avoided.
As an alternative embodiment of the embodiment, the feeding mechanism may not be provided with the feeding guide rail, and the feeding mechanism is directly conveyed by the discharge port of the feeding channel a12, and correspondingly, the side wall of the supporting table a4 blocks or separates from the discharge port. Or as a modification, the feeding component can be other than the belt conveyor a14, or the feeding component can be not arranged, and the workpiece is added into the vibrating bin a11 manually. As a further variant, the feeding mechanism may also be an existing feeder.
