  As shown in FIG. 1, in the shot blasting apparatus 10 according to the present embodiment, a projection material is projected by a projector 20 in a projection chamber 14 </ b> A onto a long processed object 12 to be conveyed. The In addition, a guide roller group 40 is provided on the conveyance line of the object to be processed 12, and the object to be processed 12 is guided to the downstream side in the conveyance direction by the guide roller group 40. Here, the object 12 to be processed is guided in the horizontal direction toward the downstream side in the transport direction in the first region 41 including the region where the projection material is projected by the projector 20, and downstream in the transport direction from the first region 41. The second region 42 on the side is guided in the upward direction toward the downstream side in the transport direction. For this reason, the deposit on the object 12 to be processed is dropped downward in the second region 42 by the air resistance and gravity during the ascending conveyance.

The first direction conversion roller 50 is disposed on the most downstream side of the first direction conversion roller 50. On the other hand, the second direction conversion roller 52 is provided downstream of the first direction conversion roller 50 in the transport direction and upstream of the third direction conversion roller 54 in the transport direction. Is also disposed on the upper side, and the winding portion 52A is set below the straight line connecting the winding portion 50A of the first direction conversion roller 50 and the winding portion 54A of the third direction conversion roller 54. Yes. For this reason, the object 12 to be processed rises in the second region 42 between the winding portion 50A of the first direction conversion roller 50 and the winding portion 52A of the second direction conversion roller 52 toward the downstream side in the transport direction. After being guided and conveyed in the direction (in a gently inclined state), it is further upward (close to vertical) between the winding portion 52A of the second direction conversion roller 52 and the winding portion 54A of the third direction conversion roller 54. (In state) guided and conveyed. Thereby, between the winding part 52A of the 2nd direction conversion roller 52 and the winding part 54A of the 3rd direction conversion roller 54, while the deposit | attachment on the to-be-processed target object 12 is dropped more effectively, the 1st The diameter of the first direction conversion roller 50 provided at the most upstream portion in the conveyance direction of the two regions 42 can be suppressed.

Such a configuration is preferable from the viewpoint of removal, but it is also possible to adopt a configuration in which the spraying device sprays gas downward on the object to be processed.

  Further, in the above embodiment, the air blower device 56 is arranged on the downstream side in the transport direction with respect to the first direction conversion roller 50 (the most upstream portion in the transport direction of the second region 42) and on the upstream side in the transport direction with respect to the second direction conversion roller 52. However, the spraying device may be disposed, for example, on the downstream side in the transport direction with respect to the second direction conversion roller (52) and on the upstream side in the transport direction with respect to the third direction conversion roller (54). The second direction conversion roller (52) may be a grooved roller having a groove formed on the outer peripheral surface, and the suction port (58A) of the suction duct (58) is in the transport direction more than the second direction conversion roller (52). You may arrange | position in the downstream.

  In the above embodiment, the suction port 58A of the suction duct 58 that communicates with the suction side of the dust collector 60 is located above the transport line of the object 12 to be processed in the second region 42 and upstream of the gas outlet 56A in the transport direction. This arrangement is more preferable from the viewpoint of effectively sucking dust and the like in the blow-off chamber 14B, but the suction port of the suction duct may be arranged at another position. Further, the number of suction ducts is not limited to the example of the above embodiment.

  Moreover, in the said embodiment, the 1st direction conversion roller 50 is made into the grooved roller by which the groove | channel 50B (refer FIG. 3) was formed in the outer peripheral surface, The to-be-processed target object 12, the 1st direction conversion roller 50, Such a configuration is more preferable from the viewpoint of facilitating removal of dust or the like that has entered between the two, but the first direction changing roller may be a roller in which no groove is formed.

  Moreover, in the said embodiment, although the six groove | channel 50B (refer FIG. 3) is formed in the 1st direction conversion roller 50 as an example, the groove | channel of the case where a groove | channel is formed in the 1st direction conversion roller is shown. The number is not limited to the example of the above embodiment.

  Moreover, in the said embodiment, the carrying-in roller 44 is made into the rubber roller, and from the viewpoint of suppressing the influence on the to-be-processed object 12 when a projection material enters between the to-be-processed object 12 and the carry-in roller 44. Although such a configuration is more preferable, the guide roller group may be configured not to include a rubber roller in the first region.

  Furthermore, in the above embodiment, the shot processing apparatus is the shot blasting apparatus 10, but the shot processing apparatus may be applied to, for example, a shot peening apparatus.

In addition, the said embodiment and the above-mentioned some modification can be implemented combining suitably.
