Technical Field

The invention relates to the technical field of conveying, in particular to a switchable feeding device.

Background

In the assembly industry of workpieces and products, the same feeding mechanism is generally used to feed different workpieces or different batches of workpieces to different stations. For example, two stations are used for receiving different workpieces, the two stations are respectively a first station and a second station, after the discharge port of the feeder conveys the first workpiece to the first station, the discharge port of the feeder is required to convey the second workpiece to the second station, at this time, the first station needs to be transferred away from the discharge port of the feeder, and the second station needs to be transferred to the discharge port of the feeder to switch the positions of the two stations, so that the discharge port of the feeder conveys the second workpiece to the second station.

The conventional switchable feeding device generally comprises a feeding conveyor, a first station and a second station which are arranged on a supporting disc, wherein the first station and the second station are positioned on the same circumference on the supporting disc, and a rotating motor for driving the supporting disc to rotate. When the rotating motor rotates to drive the supporting disc to rotate, so as to change the positions of the first station and the second station, for example, the first station is communicated with a discharge port of the feeding conveyor in a butt joint mode, and the first station is used for receiving a first workpiece; when the second workpiece is required to be received by the second station, the rotating motor continues to rotate, so that the second station rotates and is in butt joint communication with the discharge hole of the feeding conveyor, the second workpiece is received, and switching between the two stations is achieved.

However, in the switchable feeding device, when the rotary motor drives the supporting plate to rotate, the first station is transferred away from the lower part of the discharge port of the feeding machine, and the second station does not reach the lower part of the discharge port of the feeding machine, the discharge port of the feeding machine continuously outputs the second workpiece outwards, so that part of the second workpiece is bound to be scattered outwards, and the scattered second workpiece needs to be manually recovered and then loaded into the feeding mechanism, so that the feeding is inconvenient; meanwhile, if the rotary motor rotates untimely in the process of station switching, a second workpiece in the feeding machine discharging port is easily conveyed to the first station, the confusion phenomenon of two different workpieces appears on the first station, and the assembly process of subsequent different workpieces is influenced.
