Further, a cylinder driving device as the processing object discharge mechanism 11 is attached to the cylindrical support frame 9 and the opening and closing door 7, and is also used as a device for rotationally driving the large cylindrical body 10.

Further, when the large-sized cylindrical body 10 is rotated counterclockwise, the processed object 13 is moved to the right side of the lower position of the large-sized cylindrical body 10, and therefore, is disposed in front of the casing 5 in an inclined and staggered state. The two projectors 16 and 16 on the upper surface of the outer wall of the portion are provided so that the projection material can be accurately projected in the axial direction of the large cylindrical body 10 (the front-rear direction of the large cylindrical body 10) to be large. The processed material 13 at the lower portion of the cylindrical body 10 and the processed material 13 which is moved to the right side of the large cylindrical body 10 and dropped to the lower position by gravity.

The large-sized cylindrical body 10 has an octagonal shape, and includes an octagonal tubular body 27 having a small diameter and a plurality of holes 24 formed in the upper and lower portions, and a discharge port 12 formed in the cylindrical body 27, forming The bottom plate 30 and the agitating plate 35 are substantially trapezoidal, and the agitating plate 35 is composed of a stirring plate main body 32, a return plate 33, and a fall prevention portion 34. The agitating plate main body 32 is substantially triangular and is inclined. 32c is fixed to the inner wall surface of the tubular body 27, and the inclined state 32c is the rear end portion 32b of the bottom plate side of the cylindrical body 27 of the agitating plate main body 32, which is located in the rotational direction than the distal end portion 32a of the input port 31 side.

The discharge port 12 includes two substantially trapezoidal openings 26 and 26 formed in the lower wall 25 of the tubular body 27, and engaging portions 28 and 28 formed at the side portions of the openings 26 and 26, respectively. And substantially trapezoidal covers 29 and 29 that are slidably engaged with the engaging portions 28 and 28 and formed with a plurality of holes 24.

The discharge port opening device 41 includes an arm case 42 fixed to the case 5, an arm rotation cylinder 43 pivotally supported by the wall case 42, and an arm main body 45 attached to the arm rotation cylinder 43. a top end portion rotatably supported by the wall housing by a pivot support pin 44; and grip portions 47, 47 mounted to the top end portion of the arm main body 45 via the air cylinder 46, and by air pressure or Hydraulically moves left and right (see Figure 5).

When the discharge port 12 is opened, the lids 29 and 29 of the tubular body 27 are gripped by the grip portions 47 and 47 of the discharge port opening device 41, and the openings 26 and 26 are opened, and then passed through the treatment discharge mechanism 11 (cylinder). The body drive device rotates the large cylinder 10 to discharge the processed material from the openings 26 and 26. In addition, when the opening/closing door 7 of the casing 5 is opened and the tubular support frame 9 is pulled out sideways, the discharge opening device 41 is attached to the casing so as to be located at a portion where the large cylindrical body 10 is located. 5.

A locking member 36 is mounted on the casing 5 and the opening and closing door 7, and the locking member 36 is kept closed. The closed state of the opening and closing door 7 of the opening 2 of the closed casing 5 is closed. Further, the locking member 36 may be of any conventional configuration as long as it can be easily locked and unlocked.

The method of using the bead breaking device 1 having the above configuration will be described. After the large cylindrical body 10 is placed outside the casing 5, the large-sized processed material 13 to be burred is put into the large cylindrical body 10.

Next, when the opening and closing door 7 is pressed in the direction of the casing 5, the opening and closing door 7 and the tubular support frame 9 slide along the outer fixed rail 6 and the inner fixed rails 8, 8, 8 and are covered by the opening and closing door 7. After the opening 2 of the casing 5, the opening and closing door 7 is locked to the casing 5 by the locking member 36.

Then, by driving the motor 37 attached to the opening and closing door 7 of the cylinder driving device, the cylindrical driving device is driven to rotate the large cylindrical body 10.

The processed material 13 inside projects the projection material 14.

Further, when the projectors 16 and 16 are driven, when the cooling burrs are easily removed, the opening and closing valve 38 of the refrigerant supply device 23 is opened, and the refrigerant is supplied into the beating chamber 3.

The processed material 13 accommodated in the large-sized cylindrical body 10 rides on the agitating plate main body 32 by the agitating plate 35 as the large cylindrical body 10 rotates, and the processed material 13 that rides on the agitating plate main body 32 does not return to the return plate 33. When it is lifted upward, the processed object 13 slides toward the rear end portion 33b side of the returning plate 33, and falls to the bottom surface of the large cylindrical body 10.

With this configuration, the workpiece 13 can be slid while being slid in the direction of the input port 31 of the large cylindrical body 10 and the bottom plate 30 (in the longitudinal direction of the axial direction of the large cylindrical body 10). The mixture is mixed so that the processed material 13 can be efficiently stirred.

After the burrs are removed from the processed material 13 in the large cylinder 10, the driving of the projectors 16, 16 is stopped, and the cylinder driving device is also stopped.

Next, the locking of the locking member 36 is released, the opening and closing door 7 is slid in the opening direction, and the tubular support frame 9 attached to the opening and closing door 7 is also moved to the outside of the casing 5, so that the large cylinder 10 is also located in the box. Outside the body 5. Further, at this time, the discharge port 12 of the large cylinder 10 is located at the upper portion.

Then, the arm rotation cylinder 43 of the discharge opening device 41 is extended, whereby the arm main body 45 is pivoted about the pivot support pin 44 and inclined forward. Next, the grip portion 47 is opened to the left and right to further extend the arm rotation cylinder 43, and the grip portion 47 is placed on the handle portions 29a and 29a of the lid bodies 29 and 29. Thereafter, the grip portion 47 is moved in the closing direction to grip the lid bodies 29 and 29. In this state, the air cylinders 46 are extended, and the lid bodies 29 and 29 are slid in the expanding direction, and the engagement state with the engaging portion 28 of the tubular body 27 is released, and the opening portions 26 and 26 are opened. Thereafter, the arm rotation cylinder 43 is contracted to rotate the arm body 45 in a direction away from the tubular body 27. Thereafter, the tubular body 10 is rotated by the processed material discharge mechanism 11 (cylinder driving device) so that the openings 26 and 26 are located at the lower portion, and the processed material 13 after the burrs are removed from the openings 26 and 26 via the lower guide 39. The medicine storage container 40 is dropped and discharged.

When the discharge of the processed material 13 is completed, the cylindrical body 10 is rotated by the processed material discharge mechanism 11 (cylinder driving device) until the openings 26 and 26 are located at the upper portion. Next, the arm rotation cylinder 43 is extended, the lid bodies 29 and 29 are positioned in the vicinity of the openings 26 and 26, and the lids 29 and 29 are engaged with the engaging portions 28, 28, 28, and 28 by contracting the cylinders 46. The arm rotation cylinder 43 is contracted to house the arm body 45 in the arm housing 42.

Further, the openings 26, 26 are formed in a substantially trapezoidal shape, and cards are provided on both sides thereof. In the joint portions 28 and 28, the lid body 29 having a similar shape to the openings 26 and 26 is engaged with the engaging portions 28 and 28, whereby when the lid members 29 and 29 are gripped by the grip portion 47, the lids 29 and 29 are opened. By moving it in the expansion direction, the engagement state can be released with a small stroke.

Then, the opening and closing door 7 is pressed in the direction in which the opening 2 of the casing 5 is closed, and the same operation as described above is performed to perform the operation of removing the burr from the workpiece 13.
