DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for separating and conveying a sand casting, which can automatically separate and convey products, weirs, and sand in a frame releasing step in a sand casting method.

[0002]

2. Description of the Related Art Conventionally, in a frame release process in a sand casting method, sand is separated from a product with a weir in a first step, and the product and a weir are cut and separated in a second step. Conventionally, since workers cut high-temperature products and weirs in dust and sort them by hand, the working environment was extremely poor, and the workplace was a 3K workplace with danger.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned conventional problems, and is a sand mold capable of separating sand, separating products and weirs, sorting and automatically conveying the sand. The purpose of the present invention is to provide a casting separation / transportation device.The gist of the purpose is to provide a weir portion of an unframed sand casting in a transport booth provided on a vibrating device that vibrates in the transport direction. A rail that can be placed and support the product portion in a suspended manner; a stopper that is provided at a predetermined position in the transport direction of the rail and that can contact the weir portion to separate the weir portion; A product transfer mesh provided to receive the separated and dropped product portion, and a lower sand transfer surface for receiving the sand falling through the product transfer mesh,
That is, they are arranged along the transport direction.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall side view of the apparatus 1 for separating and conveying sand-cast products, FIG. 2 is an enlarged front view of a main part of the apparatus for separating and conveying, and FIG. FIG.

[0005] In the figure, a separating / transporting device 1 is provided with a vibrating device 2 at a lower portion, and a conveying booth 3 is arranged on the vibrating device 2.
Is configured such that a plurality of vibration generators 5, 5, 5 are attached to a base 4 at predetermined intervals, and each vibration generator 5 is driven by a motor and eccentrically rotates to generate vibration. Each of the vibration generators 5 is arranged so as to be able to apply vibration in the transport direction from the left side to the right side in the drawing. That is, the vibration generators 5, 5 and 5 apply vertical vibrations in an inclined manner from left to right.

A transfer booth 3 provided on the vibrating device 2 along the transfer direction from left to right, as shown in an enlarged view in FIG. 2, has an upper frame 6 and vertical frames 7, 7 in a gate frame shape. Are provided from the upper frame 6 and hanging bars 8 are provided. Support bars 9 and 9 connected to the hanging bars 8 and extending inward in the horizontal direction from the vertical frames 7 and 7 on both sides are provided. Rails 10, 10 are arranged facing each other with a gap formed between opposing inner end faces of the support bars 9, 9, and are cast into the gap between the rails 10, 10 by a sand casting method. It is configured so that the weir Sb of a cast product can be placed thereon, and in a state where the weir Sb is placed on the pair of rails 10, the part of the product Sa hanging from the weir Sb is a rail 10.
It is configured to be supported in a hanging manner below the lower part 10.

Below the rails 10, 10, a product transport mesh 12 is provided substantially horizontally in parallel with the rails 10, 10, and the product transport mesh 12 is formed into a mesh shape through which sand can pass. A lower gutter section 11 having a cross-sectional gutter shape to which the lower ends of the vertical frames 7, 7 are fixed.
The bottom surface of the lower gutter portion 11 forms a sand transport surface 11a which is substantially parallel to the product transport mesh 12 and receives sand. That is, in the transport booth 3 of the present example, the rails 10 and 10 are disposed above, the product transport mesh 12 is disposed below and parallel to the rails 10, and the sand transport surface 11a is further disposed below. Has become.

As shown in an enlarged view of a main part of FIG. 3, a stopper 15 is disposed at a predetermined position on the rails 10, 10. Pulley 14 through
The weir Sb is placed on the rails 10 and 10 so that the product S
The stopper 15 is brought into contact with the weir Sb in the middle of being transported from the left to the right in the suspended state, and vibration is applied together with the contact force of the stopper 15, whereby the weir Sb is cut and separated from the product Sa. After the weir Sb is separated, the stopper 15 is configured to operate the cylinder 13 to move upward and release the stopper.

In such a configuration, in the unraveling step after the casting operation into the sand mold is finished, the product S with sand is formed.
a and the weir Sb are pushed by the actuator, and FIG.
Is placed on the rails 10 in such a state, and the vibration of the vibration device 2 in this state is an inclined vibration capable of applying a conveying force from the left to the right.
The weir Sb vibrates and moves from 0 to 10 from left to right while the product Sa is suspended, and the sand is first separated by the vibration, and the sand passes through the product transfer mesh 12 and the lower sand transfer surface 1.
1a, and is conveyed to the rightmost exit side while the sand ball is broken by vibration.

When the weir Sb on the rails 10, 10 reaches a predetermined position, as described above, the stopper 15 comes into contact with the base of the weir Sb as shown in FIG. The weir Sb is separated from the product Sa, and the product Sa falls downward and is placed on the product transport mesh 12, and is gradually transported to the right end exit side by the vibration applied to the product transport mesh 12. At the same time, the separated weir Sb is conveyed to the right end exit side by vibration on the rails 10 and 10, and the sand is automatically separated, and the weir Sb and the product Sa are separated.
In the sorted state, the products, the weir, and the sand are conveyed by vibration to the rightmost outlet side, and can be automatically conveyed to the next process. All the steps that have been manually sorted are automated, and the work can be reduced.

[0011]

According to the sand casting separation / transportation apparatus of the present invention, a weir portion of an unframed sand casting is placed in a transportation booth provided on a vibrating device for applying vibration in the transportation direction. A rail capable of supporting the product portion in a suspended manner, a stopper provided at a predetermined position in the conveyance direction of the rail and capable of contacting the weir portion and separating the weir portion, and a lower portion of the rail. The product transport mesh that is provided to receive the separated and dropped product portion and the lower sand transport surface that receives the sand that falls through the product transport mesh are arranged along the transport direction, so that First, the sand is separated, and the sand is conveyed while vibrating on the sand conveying surface.The weir portion placed on the rail is separated by the stopper and conveyed along the rail. Done The product is placed on the product transport mesh and transported, and the separation and transport are automatically performed, and all the separation and sorting operations that were conventionally performed manually can be automated and performed. This has the effect that the work involved can be reduced by automation.
