(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a blast device 100 according to a first embodiment of the present invention.

  A blasting apparatus 100 according to the first embodiment includes a belt conveyor 1 corresponding to a first transport unit, a first blast unit 111, a reversing mechanism 2, and a belt conveyor 3 corresponding to a second transport unit. And a second blast part 112. The blast units 111 and 112 further include injection ports 12 and 14 and rotors 15 and 16.

  Further, the blasting apparatus according to the first embodiment includes a storage hopper 10, projecting material supply pipes 11, 13, a cut gate 17, a support member 7, contact sensors 8, 9, and a work inlet. 101 and a work outlet 102 are further provided.

  The workpiece W, which is a workpiece, is carried in from the carry-in entrance 101. The belt conveyor 1 conveys the loaded work W. The belt conveyor 3 conveys the workpiece W and carries it out to the carry-out port 102. The blast parts 111 and 112 eject the projection material from the ejection ports 12 and 14 by the rotors 15 and 16 to the workpiece W conveyed by the belt conveyors 1 and 3. The storage hopper 10 supplies the projection material to the blast parts 111 and 112 via the projection material supply pipes 11 and 13. The cut gate 17 adjusts the supply amount of the projection material supplied from the projection material supply pipe 11 to the blast unit 111 by opening and closing. The contact sensors 8 and 9 detect that the workpiece W has passed a predetermined position. The support member 7 supports the reversing mechanism 2 so as to be rotatable.

  FIG. 2 is a diagram showing the reversing mechanism 2 according to the first embodiment of the present invention. The reversing mechanism 2 includes a rotating shaft 22, a rotary cylinder 23 corresponding to a drive unit, a bottom surface portion 21 corresponding to a receiving portion, a side surface portion 24, a back surface portion 25, and an upper surface portion 26. The bottom surface portion 21 receives the workpiece W falling from the end E of the first transport unit 1 and reverses the workpiece W by a reaction force in the inclination of the bottom surface portion 21. The reversing mechanism 2 can be rotated around a rotation shaft 22, and the shape of the workpiece W, the weight of the workpiece W, the conveyance speed of the belt conveyor 1 and the belt conveyor 3, the belt conveyor 1 and the belt are rotated by the rotary cylinder 23. The rotation range, the rotation speed, and the rotation acceleration are controlled according to at least one of the conveyance acceleration of the conveyor 3 and the shape of the end portion E. The side surface portion 24, the back surface portion 25, and the top surface portion 26 hold the workpiece W received by the bottom surface portion 21 in the reversing mechanism 2.

  Next, the operation of the blast apparatus 100 will be described. First, as shown in FIG. 1, the workpiece W is sequentially carried into the blast apparatus 100 from the carry-in entrance 101 by the belt conveyor 1. In the middle of being conveyed by the belt conveyor 1, the workpiece W passes under the ejection port 12 of the blast unit 111. The workpiece W blasted by the blast unit 111 is conveyed to the end E of the belt conveyor 1 and falls from the end E to the reversing mechanism 2. When the work W falls to the reversing mechanism 2, the work W comes into contact with the contact sensor 8, and the contact sensor 8 detects that the work W has entered the reversing mechanism 2. When the contact sensor 8 detects the passage of the workpiece W, the belt conveyor 1 stops. By stopping the belt conveyor 1, it is possible to prevent a plurality of workpieces W from entering the reversing mechanism 2 at a time, and the workpieces W can be reliably reversed one by one. When the contact sensor 8 detects the passage of the workpiece W, the cut gate 17 is closed, and the supply of the projection material from the projection material supply pipe 11 to the blast unit 111 is stopped. By stopping the supply of the projection material at the same time as stopping the belt conveyor 1, a part of the workpiece W stationary under the blasting part 111 is prevented from being blasted for a long time, and the blasting process in the workpiece W is performed.
