Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum tilting mechanism of a continuous blasting apparatus for continuously blasting an object to be processed which is moved and passed through a drum.

[0002]

2. Description of the Related Art Conventionally, in a continuous blast apparatus as described above, the drum is tilted and adjusted so that the blast processing can be performed by changing the moving speed depending on the type of the article to be processed. One example is Japanese Patent Application Laid-Open No. 6-14344.
As shown in Japanese Patent Application Laid-Open Publication No. H10-163, there is known a tilting frame on which a drum is mounted, in which one end is rotatable up and down to support a shaft and the other end can be raised and lowered by a cylinder.

[0003]

However, in the above-described drum tilting mechanism, a heavy object such as a drum and a tilting frame supporting the drum is tilted to an appropriate tilt angle by a cylinder in accordance with the type of a workpiece. This has to be maintained, and there is a problem that the cylinder is always under pressure, buckling occurs in the cylinder, damaging the sealing material and causing oil leakage, etc. The present invention has been made in view of the above-described problems, and has as its object to provide a drum tilting mechanism of a continuous blasting device that can reliably perform tilt adjustment of a drum with a simple mechanism without adversely affecting a cylinder. I do.

[0004]

In order to achieve the above object, a drum tilting mechanism of a continuous blasting apparatus according to the present invention is arranged such that a lower portion of one end of a tilting frame on which a drum is installed is rotated up and down on a support base provided on a base. A stay support, which supports the lower frame near the other end of the tilting frame and the base via a lifting cylinder, and which is provided with a stepped notch near the lifting cylinder on the base. A table is installed, and a lower extending stay is rotatably suspended in correspondence with the stepped groove on a lower surface corresponding to a stay receiving table of the tilting frame, and a central portion of the stay and the tilting frame are provided. Are connected via an adjusting cylinder.

[0005]

Embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, a tall support 2 is installed on one end (left end in FIG. 1) of the base 1, and one end of a tilting frame 3 is vertically connected via a connecting pin 4 on the support 2. It is rotatably supported.
An elevating cylinder 6 is provided on the upper part of the base 1 near the other end (the right end in FIG. 1) via a mounting base 5 so as to be able to rotate left and right. The tip of a piston rod 6A of the elevating cylinder 6 is The tilting frame 3 is connected to a lower portion near the right end so as to be rotatable left and right.

Further, at a position near the elevating cylinder 6 in the mounting table 5, a stay receiving table 8 provided with grooves 7, 7 whose surface is cut out stepwise is mounted. Also, on the lower surface of the tilting frame 3 corresponding to the stay support 8,
A stay 9 extending downward is rotatably suspended from the stepped grooves 7,7. Further, the stay 9
Adjustment cylinder 1 between the central portion of
The stay 9 can be stopped by the operation of the adjusting cylinder 10 in any of the grooves 7.

A confirmation sensor 11 for confirming the setting of the stay 9 is provided on an upright surface of each of the grooves 7, 7 of the stay receiving stand 8, and a lower end of the stay 9 is provided with the confirmation sensor 11. A detection sensor 12 for detecting that each groove 7 corresponds to each groove 7 is provided. Further, a spacer mounting structure (not shown) in which a spacer 13 is made detachable is formed on each bottom surface of each groove 7, 7 of the stay receiving base 8.

[0008] The apparatus constructed as described above performs the following operation according to the article to be blasted. First, the elevating cylinder 6 is extended to rotate the drum (not shown) together with the tilting frame 3 around the connecting pin 4 and the stay 9 is once lifted from the stay receiving stand 8. Next, the adjusting cylinder 10 is operated to make the stay 9 correspond to the required groove 7. At this time, it is detected by the detection sensor 12 provided at the lower end of the stay 9 that it is opposed to the necessary groove 7. Next, the raising / lowering cylinder 6 is contracted to lower the tilting frame 3 and the drum (not shown), and the lower end of the stay 9 contacts the corresponding groove 7 to stop the lowering. Being supported.

When the inclination angle of the drum is not sufficient only by the engagement between the groove 7 and the stay 9, the spacer 13 can be attached to the groove 7 to finely adjust the inclination angle of the drum. Therefore, in FIG. 1, since five grooves 7, 7 are provided, at least ten kinds of inclination angles can be selected. When the inclination angle of the drum is not so large, the stay receiving part is not required. Grooves 7, 7 of table 8
Can be reduced to make the stay receiving stand 8 smaller. In this way, the continuous blasting process is started by adjusting the inclination angle of the drum so as to optimize the feed speed of the article to be processed. Next, when the object to be processed changes and the inclination angle of the drum is changed, an operation of adjusting the inclination angle according to the object to be processed is performed in the same manner as described above.

[0010]

According to the present invention, as is apparent from the above description, the lifting and lowering of the drum is performed by the raising and lowering cylinder, and the tilt of the drum is adjusted by the engagement between the groove notched stepwise and the stay. Because of the drum tilting mechanism described above, the tilt angle can be surely adjusted without adversely affecting the cylinder.
