[Problems to be solved by the invention]
However, some mesh strainers are curved under the influence of the mesh material, and the peripheral edge is warped upward, so that the tip of the wedge-shaped locking member has the lowermost strainer and the strainer thereon. In some cases, the lowermost strainer cannot be separated, and as a result, the strainer cannot be supplied to the mold.
[0005]
An object of the present invention is to eliminate the above-mentioned disadvantages.
[0006]
[Means for Solving the Problems]
In order to achieve this object, in a casting strainer mounting device according to the present invention, a strainer housing cylinder is installed on a base and a slide member is relatively slidable with respect to the base by driving means, A wedge-shaped locking member protrudes from the slide member toward the strainer storage cylinder, and a casting strainer passage is provided on the strainer storage cylinder side from the wedge-shaped locking member, and at least the wedge-shaped locking member of the strainer storage cylinder is provided. A casting strainer stopper is provided on the opposite side to the lowermost casting strainer accommodated in a stacked state in the strainer accommodating cylinder by the slide member advancing toward the strainer accommodating cylinder, and a casting thereon. The wedge-shaped locking member is made to enter between the strainer and the casting strainer, and the lowermost casting strainer is separated. In the casting strainer separating device for discharging from the manufacturing strainer passage below the base, a lid is provided on the strainer housing cylinder, and an advance / retreat rod is inserted into the lid so as to be able to advance and retreat, and the tip of the advance / retreat rod is pressed. Since the member is fixed and the pressing member is fitted in the strainer housing cylinder, even the curved casting strainer is pressed downward by the weight of the pressing member in a state of being superposed substantially horizontally.
[0007]
In addition, if the advancing / retracting rod is urged to the distal end side by a tensile elastic member, the casting strainer superimposed with the pressing member can be pressed downward, so that the wedge-like shape is obtained even if the peripheral edge of the casting strainer is warped upward. The locking member can more easily penetrate between the lowermost strainer and the strainer thereabove, and thus more reliably supply the strainer to the mold.
[0008]
If a tension spring is used as the tension elastic member, the casting strainer mounting device can be easily manufactured and can be easily maintained.
[0009]
Also, if a proximity switch is installed on the lid and a dog is installed on the forward / backward rod, and the proximity switch is turned on when the dog approaches, the position of the dog is adjusted by adjusting the position of the dog. Since the position of the advancing / retreating rod with respect to the lid can be electrically notified, the casting strainer mounting device can be easily managed.

When it is moved forward and placed on the shelf board 12, it is positioned horizontally, and when it retreats and comes off the shelf board 12, as shown by a solid line in FIG. It is located in an inclined state toward B. At this time, since the cross section of the edge 121 of the shelf 12 is formed in an arc shape, the slide member 20 can smoothly swing as it protrudes from the edge 121 of the shelf 12. As a result, the strainer S can be smoothly dropped to a predetermined position. As described above, the shooter 27 can receive the strainer S in a horizontal state (see FIG. 4), and can attach the strainer S to the spout B in an inclined state (see FIG. 1).
[0027]
Next, the operation of the casting strainer mounting device M will be described.
[0028]
First, the support member 58 is lifted up against the tension spring 59, and the protrusion 582 is removed from the upper end recess of the advance / retreat rod 54. Then, while opening the lid 53, the advance / retreat rod 54 is lifted, and the pressing member 55 is taken out of the strainer housing cylinder 50. In this state, the required number of stacked strainers S is filled into the strainer housing cylinder 50 by an appropriate method. Then, the cover 53 is closed while the pressing member 55 is inserted into the strainer housing cylinder 50. Then, the support member 58 is lifted up against the tension spring 59, and the projection 582 is locked in the upper end recess of the advance / retreat rod 54. In this state, even if the stacked strainers S are curved, the strainers S can maintain a substantially horizontal state in the strainer housing cylinder 50 by the weight of the pressing member and the elastic force of the tension spring 59.
[0029]
Then, the piston / cylinder mechanism P is operated to move the slide plate 20 forward (to the right in FIG. 1) (see FIG. 1). Then, when approaching below the strainer housing cylinder 50, as shown in FIG. 4, the anti-locking member 22 side of the strainer S is stopped from moving forward by the projection 52, so that the locking member of the slide plate 20 is locked. 22 starts to separate the edge of the lowest end of the strainer S, and further guides it to the strainer passage hole 21 while moving forward. The strainer S that has passed through the strainer passage hole 21 falls and is accommodated in a lower shooter (horizontal state) 27. In this state, the piston / cylinder mechanism P is temporarily stopped and then operated again to move the slide plate 20 backward. Then, the shooter 27 is disengaged from the shelf board 12 and is inclined, so that the strainer S can be attached to the sprue portion B. When the slide plate 20 retreats, the next remaining strainer S is locked to the projection 52 on the locking member side, and therefore does not move following the slide plate 20.
[0030]
Further, in this embodiment, the rear end of the shooter 27 is swingably installed on the slide member 20, and is moved forward and backward on the shelf 12 together with the slide member 20, and the edge of the shelf 12 is When the cross section of is circular, the slide member 20 smoothly swings as it protrudes from the edge of the shelf 12, so that the strainer S can be smoothly dropped to a predetermined position.
[0031]
Further, in this embodiment, since the tip of the strainer housing tube 50 and the slide member 20 are not in contact with each other, the slide member 20 can always maintain a constant position with respect to the strainer housing tube 50. The positional relationship between the strainer S housed in the strainer housing cylinder 50 and the locking member 22 is always constant, and therefore, the strainer S can be easily separated in a stable state.
[0032]
In this embodiment, since the slide member 20 is provided with the slide groove 25 and the strainer housing cylinder 50 is provided with the projections 52, 52,... As a result of restricting the position of the tube 50 with respect to the slide member 20 in the forward and backward directions and the vertical direction, the positional relationship between the strainer S housed in the strainer housing tube 50 and the locking member 22 is always constant, and thus a stable state is achieved. This makes it easy to separate the strainer S.
[0033]
Further, if the tip of the hook member 22 is sharpened in a V-shape, even if the strainer S is a net, it can be separated smoothly.
[0034]
Further, if the cross section of the tip of the locking member 22 is sharpened in a V-shape, when the strainer S is separated, the lowermost strainer S from the plurality of overlapping strainers S, S,. It is easy.
[0035]
