Abstract

A bulk feeder includes a feeder main body, a receiving member provided on the feeder main body and formed with a receiving region configured to receive a component discharged from a component case accommodating multiple components, a track member provided to be vibratable with respect to the feeder main body and formed with a conveyance path through which the multiple components are conveyed and a supply region that communicates with the conveyance path and opens upward to collect the multiple components, an excitation device configured to apply vibration to the track member so that the multiple components are conveyed along the conveyance path, and a connection member having flexibility and configured to connect between the receiving region and the conveyance path so that the multiple components flows through.

Claims (15)

1 . A bulk feeder comprising:

a feeder main body;

a receiving member provided on the feeder main body and formed with a receiving region configured to receive a component discharged from a component case accommodating multiple components;

a track member provided to be vibratable with respect to the feeder main body and formed with a conveyance path through which the multiple components are conveyed and a supply region that communicates with the conveyance path and opens upward to collect the multiple components;

an excitation device configured to apply vibration to the track member so that the multiple components are conveyed along the conveyance path;

a connection member having flexibility and configured to connect between the receiving region and the conveyance path, the connecting member having a tubular shape in which the multiple components flows through;

an air supply device configured to supply positive pressure air to flow the multiple components from the receiving member to the track member via the connection member; and

a controller including a processor configured to control the excitation device and the air supply device such that when the excitation device is operating, the air supply device is stopped, and when the air supply device is operating, the excitation device is stopped.

2 . The bulk feeder according to claim 1 , wherein the connection member absorbs vibration by being deformed in accordance with vibration of the track member when the track member is excited by the excitation device, and alleviates or blocks vibration transmitted to the receiving member.

3 . The bulk feeder according to claim 1 , wherein the connection member is a coil spring.

4 . The bulk feeder according to claim 3 , wherein the connection member is formed of a metal material.

5 . The bulk feeder according to claim 1 , wherein the connection member is formed of resin or rubber as a material.

6 . The bulk feeder according to claim 1 , wherein the receiving member is disposed below the track member.

7 . The bulk feeder according to claim 1 , wherein the receiving member has an inclined portion inclined with respect to a horizontal plane at least a portion of the receiving region.

8 . The bulk feeder according to claim 7 , wherein the inclined portion is located below a discharge port of the component case and has a planar shape.
