Utility Model Registration No. 2602327

  In the above-mentioned conventional apparatus, the opening is greatly opened over the entire area when the cover is open, so that the cover is large so as to correspond to the opening area of the opening. Yes. An increase in the size of the lid means that the stroke when moving the lid horizontally between the open position and the closed position becomes longer. The space to be secured will be increased.

  As a countermeasure, the lid is connected to the barrel tank by a hinge, and only a part of the upper surface of the barrel tank is opened and closed by the lid. A structure that is always closed can be considered. In this way, when the lid is opened, it is not necessary to retract the lid so that it protrudes to the side of the barrel tank, so there is no need to provide a space for opening and closing the lid on the side of the barrel tank.

  However, when manually loading the mass, the position where the worker stands when the mass is loaded must be set to a position different from the hopper that receives the discharged mass, so that the loading operation is facilitated. And an opening suitable for discharging are set in different areas. In such a form, when one of the two openings is to be enlarged, if the enlarged area interferes with the opening area of the other opening, the other opening must be narrowed. Don't be. For this reason, if the opening for opening is widened to give priority to the ease of the charging operation, there is a concern that the discharge efficiency will decrease, and conversely, if the opening for discharging is widened with priority given to the discharging efficiency, There is a concern that it will interfere.

  The present invention has been completed on the basis of the above-described circumstances, and uses a lid in which a loading opening and a discharging opening provided on the upper surface of a barrel tank are swingably supported by a hinge. It is an object of the present invention to provide a barrel polishing apparatus that can be opened and closed separately, so that both the opening area of the input opening area and the opening area of the discharge opening area can be secured large.

  As means for achieving the above object, the invention of claim 1 is fixed to the bottomed cylindrical barrel tank and the barrel tank in a form in which the opening on the upper surface of the barrel tank is partially closed. A closing member provided as a closing member, a closing lid member capable of opening and closing a part of the opening region of the opening not corresponding to the closing member, and the closing member and the closing lid member in the opening. A discharge lid member capable of opening and closing a part of the non-corresponding opening area, and a common lid member capable of opening and closing the opening area not corresponding to the closing member, the charging lid member and the discharge lid member in the opening. The closing lid member is attached to the closing member so as to be swingable about a first axis in a direction crossing the opening, and the discharging lid member is attached to the closing member. On the other hand, the direction intersecting the first axis, The shared lid member is swingably mounted about the second axis with respect to the charging lid member, and is attached to the discharge lid member. It is characterized in that it is attached to the lid member so as to be swingable about the first axis.

  According to a second aspect of the present invention, in the first aspect of the present invention, the cylinder body of an air cylinder is attached to the closing member so as to be swingable about a support shaft parallel to the first shaft, The lid member is characterized in that a rod extending from the cylinder body is attached so as to be swingable about a connecting shaft parallel to the first shaft.

<Invention of Claim 1>
In a state where all of the charging lid member, the discharging lid member, and the common lid member close the opening, when the swinging lid member and the common lid member are swung in the opening direction around the first axis, An opening area that does not correspond to the closing member and the discharge lid member in the opening is opened as a loading opening area, so that a mass can be poured into the barrel tank from the loading opening area.

  When all of the closing lid member, the discharging lid member, and the common lid member close the opening, when the ejection lid member and the common lid member are swung in the opening direction around the second axis, Since the opening area that does not correspond to the closing member and the charging lid member is opened as the discharge opening area, the mass in the barrel tank can be discharged from the discharge opening area.

  The opening area that is opened and closed by the common lid member in the opening can be shared by both the opening area for discharging and the opening area for discharging. Therefore, the opening area of the opening area for opening and the opening area of the opening area for discharging Both of these can be secured greatly.

<Invention of Claim 2>
Since the closing lid member and the common lid member are opened and closed using the driving force of the air cylinder, the burden on the operator is reduced.

The first hinge 20 includes a support member 21 fixed at a position near the right edge on the upper surface of the closing member 18, and a swing member 22 fixed at a position near the left edge on the upper surface of the closing lid member 19. The first shaft 23 connects the members 21 and 22 so as to be relatively rotatable.

  On the projection surface projected onto the opening 11 from above, the first axis 23 is oriented such that its extension line linearly crosses the opening 11 of the opening 11 in the front-rear direction. The first shaft 23 is located slightly to the left of the center of the opening 11 (that is, the right edge of the closing member 18 and the left edge of the closing lid member 19) in the left-right direction. In the vertical direction (a direction perpendicular to the upper surface of the closing member 18), it is located above the upper surface of the closing member 18 and the upper surface of the closing lid member 19.

  The discharge lid member 24 is made of a flat plate member made of metal, and has an arcuate edge extending in an arc shape from the rear end to the left front, and a front edge extending linearly from the front end of the arcuate edge to the right. And a straight right-side edge extending perpendicularly from the right end of the front edge portion to the rear end of the arc-shaped edge portion. The discharge lid member 24 has an opening area behind the closing member 18 in the left half area of the opening 11 (that is, an opening area not corresponding to the closing member 18 and the charging lid member 19 in the opening 11). It opens and closes.

  When the discharge lid member 24 is in a closed state in which the opening 11 is closed, the arc-shaped edge of the discharge lid member 24 is arranged so as to overlap the opening edge of the opening 11 concentrically from above. The front end of the arcuate edge is arranged adjacent to the rear of the rear end of the arcuate edge of the closing member 18. Further, the right edge of the discharge lid member 24 is arranged in the front-rear direction so as to be aligned with the right edge of the closing member 18. Furthermore, the front edge of the discharge lid member 24 extends in the left-right direction at a position slightly behind the center of the opening 11 and is arranged along the rear edge of the closing member 18.

  The discharge lid member 24 is swingably supported by a single second hinge 25 with respect to the closing member 18. The second hinge 25 includes a pair of front and rear connecting plates 26 fixed to a position in the vicinity of the rear edge on the upper surface of the closing member 18 and a position in the vicinity of the front edge on the upper surface of the discharge lid member 24. It is comprised from the 2nd axis | shaft 27 which connects the connection board 26 so that rotation is relatively possible.

  On the projection surface projected onto the opening 11 from above, the second axis 27 is oriented so that its extension line linearly crosses the opening 11 of the opening 11 in the left-right direction, that is, with the first axis 23. It is in a direction that intersects at a right angle. The second shaft 27 is located in the middle between the rear edge portion of the closing member 18 and the front edge portion of the discharge lid member 24 in the front-rear direction, and is in the vertical direction (perpendicular to the upper surface of the closing member 18). In the direction), it is disposed at a position slightly above the upper surface of the closing member 18 and the upper surface of the discharge lid member 24, that is, at a position closer to the upper surface of the closing member 18 than the first shaft 23.

  The shared lid member 28 is made of a metal flat plate member that is symmetrical to the discharge lid member 24, and has an arcuate edge extending in an arc shape from the rear end to the right front, and a left side from the front end of the arcuate edge portion. A front edge extending linearly to the left side, and a straight left side edge extending perpendicularly from the left end of the front edge to the rear and continuing to the rear end of the arcuate edge. This common lid member 28 is an opening area behind the opening area opened and closed by the closing lid member 19 in the right half area of the opening 11 (that is, the closing member 18 in the opening 11, the closing lid member 19 and The discharge lid member 24 and the non-corresponding opening area) are opened and closed.

  When the shared lid member 28 is in a closed state that closes the opening 11, the arc-shaped edge of the shared lid member 28 is arranged so as to overlap the opening edge of the opening 11 concentrically from above, The front end of the edge is arranged so as to be adjacent to the rear of the rear end of the arcuate edge of the charging lid member 19. Further, the left side edge of the shared lid member 28 is arranged in the front-rear direction so as to be aligned with the left side edge of the closing lid member 19. Furthermore, the front edge portion of the shared lid member 28 extends in the left-right direction at a position slightly behind the center of the opening 11 and is arranged along the rear edge portion of the closing lid member 19.

  The common lid member 28 is supported by the second lid 25 so as to be swingable about the second shaft 27 with respect to the charging lid member 19, and one first lid with respect to the discharge lid member 24. The hinge 20 is supported so as to be swingable about the first shaft 23. The second hinge 25 that supports the shared lid member 28 has the same form as that that supports the discharge lid member 24 on the closing member 18, and the first hinge 20 that supports the shared lid member 28 also has The closing member 18 has the same form as that supporting the closing lid member 19.

  The closing lid member 19 is opened and closed by an air cylinder 30. The air cylinder 30 has a well-known configuration including a cylinder body 31 and a rod 32 protruding from the tip of the cylinder body 31. The cylinder body 31 is swingably supported by a support shaft 34 so as to swing the head in the vertical direction with respect to a bearing arm 33 provided on the upper surface of the closing member 18. The tip of the rod 32 is supported by a connecting shaft 36 so as to swing in the vertical direction with respect to a connecting member 35 provided on the upper surface of the closing lid member 19.

  Both the axis of the support shaft 34 and the axis of the connecting shaft 36 are parallel to the first shaft 23. Further, the support shaft 34 is disposed above the first shaft 23 in the vertical direction. When the closing lid member 19 is in the closed state, the connecting shaft 36 is higher than the first shaft 23 and lower than the support shaft 34 in the vertical direction.

Next, the operation of this embodiment will be described.
When the mass is introduced into the barrel tank 10 from the state where the opening 11 of the barrel tank 10 is closed over the entire area, the air cylinder 30 is driven to contract the rod 32. Then, the connecting member 35 is pulled leftward so that the closing lid member 19 is lifted upward about the first shaft 23 as shown by a solid line in FIG. 2 and an imaginary line in FIG. Swing. The closing lid member 19 is connected to a common lid member 28 via a second hinge 25. The common lid member 28 has the same first axis as the swing center of the closing lid member 19. Since the discharge lid member 24 is also supported by the first hinge 20 having the 23, the common lid member 28 maintains the substantially same posture as the loading lid member 19, and the loading lid member 19. And swings upward about the first hinge 20.

  By swinging the closing lid member 19 and the common lid member 28 in the opening direction, the semicircular closing opening area which is the right half area of the opening 11 is opened largely. At this time, the closing lid member 19 and the common lid member 28 are opened while being displaced to the left opposite to the position where the operator stands (the position on the right side of the barrel tank 10) in order to load the mass. Therefore, when an operator inputs a mass from the right side of the barrel tank 10, the input operation is not hindered.

  When the mass charging operation is completed, the air cylinder 30 is driven, the charging lid member 19 and the common lid member 28 are returned to the closed state, and the opening 11 is closed over the entire region. Then, the motor 17 is started and the polishing operation by the barrel tank 10 is performed. During the polishing, the opening 11 of the barrel tank 10 is closed, so that the sound generated along with the polishing in the barrel tank 10 is difficult to leak to the outside of the barrel tank 10. Further, dust generated with the polishing is prevented from rising outside the barrel tank 10. Further, since the closing lid member 19 is held in the closed state by the air cylinder 30, there is no possibility that the closing lid member 19 flutters up and down due to vibration of the barrel tank 10 generated during polishing.

  After the polishing process is completed, as shown in FIG. 5, the barrel tank 10 is inverted to the discharge posture so as to be tilted backward. When the backward tilt angle from the polishing posture of the barrel tank 10 exceeds 90 ° in the process of reversal, the mass in the barrel tank 10 moves to the opening 11 side along the inner periphery of the barrel tank 10 by its own weight. At the same time, the discharge lid member 24 and the shared lid member 28 start swinging in the lid opening direction due to their own weight. By the swinging of the discharge lid member 24 and the common lid member 28 in the opening direction, the discharge lid has a comb shape behind the region of the opening 11 that is closed by the closing member 18 and the closing lid member 19. The opening area is opened, and from here, the mass is discharged out of the barrel tank 10 and falls onto the hopper 15.

  The opening area of the discharge opening area is narrower than that of the input opening area. In addition, the discharge opening region is a region in which the region opened and closed by the discharge lid member 24 and the region opened and closed by the common lid member 28 are combined. Of the discharge opening regions, the common lid member The area opened and closed by 28 also serves as a part of the input opening area. Further, when the barrel tank 10 is inverted, the closing lid member 19 is held in the closed state by the air cylinder 30, so that the area closed by the closing lid member 19 in the closing opening area is closed. Keep it as it is.

  When the discharge of the mass is completed, the barrel tank 10 is returned to the polishing posture. In the returning process, the opening degree of the discharge lid member 24 and the common lid member 28 gradually decreases, and when the barrel tank 10 returns to 90 ° with respect to the polishing posture, the discharge lid member 24 and the common lid member 28 are returned. Is almost closed. Thereafter, the discharge opening region is kept closed until the barrel tank 10 reaches the polishing posture.

  As described above, the barrel polishing apparatus according to the present embodiment includes the lid member 19 that supports the input opening and the discharge opening provided on the upper surface of the barrel tank 10 so as to be swingable by the hinges 20 and 25. 24 and 28, which are opened and closed separately, and even if the opening area for injection and the opening area for discharge are set adjacent to each other, the opening of the opening area for injection The purpose is to secure both the area and the opening area of the discharge opening region.

  Then, as a means for solving the problem, the closing lid member 19 is attached to the closing member 18 so as to be swingable around the first shaft 23 in a direction that crosses the opening 11 linearly, and the discharging lid member 24 is attached. The closing member 18 is attached to the closing member 18 so as to be swingable around the second shaft 27 in a direction intersecting the first shaft 23 and linearly crossing the opening 11. The member 19 is attached so as to be swingable about the second shaft 27 and attached to the discharge lid member 24 so as to be swingable about the first shaft 23.

  As a result, the opening area opened and closed by the shared lid member 28 in the opening 11 can be shared by both the opening area for input and the opening area for discharge that are set to be adjacent to each other. . Therefore, both the opening area of the input opening area and the opening area of the discharge opening area can be secured large.

  A cylinder body 31 of an air cylinder 30 is attached to the closing member 18 so as to be swingable about a support shaft 34 parallel to the first shaft 23, and is extended from the cylinder body 31 to the closing lid member 19. The rod 32 is attached so as to be swingable about a connecting shaft 36 parallel to the first shaft 23. Thereby, since the closing lid member 19 and the common lid member 28 can be opened and closed using the driving force of the air cylinder 30, the burden on the operator is reduced.
