Abstract

PURPOSE:To improve the efficiency of a casting treatment by disposing cyclically respective stations for casting take-out, sand striping, product sepn. and waste material recovery and transferring successively the castings grasped with a movable unit to each station. CONSTITUTION:The casting take-out station S1 is provided to the prescribed position on a pouring line B and the sand stripping, product sepn. and waste material recovery stations S2, S3, S4 are successively disposed to the angle positions of 90 deg. each. Plural sprue clamping devices 9 are vertically attached to the unit 1. The devices 9 clamp the casting sprues W21 in the station S1. The castings are transferred in the clamped state through the stations S2, S3, S4 by a lifting device 8 by which the sand stripping, product sepn. and waste material recovery are executed. The efficiency of the casting treatment is considerably improved by the above-mentioned method.

Description

[Detailed description of the invention]

(Industrial Field of Application) The present invention relates to a casting processing apparatus for removing and processing castings from a sand mold after pouring in a pouring line. (Prior art) Conventionally, in the Note 4 line for casting molds, the castings formed in the sand mold are taken out from the sand mold and then subjected to shot blasting or the like. 11 The sand is dropped and processed, and then separated into waste parts such as sprues and product parts and sorted (puro processing is performed). is JP-A-5B
There is something similar to that disclosed in the 50966 Bow Publication,
In addition, devices that separate and sort (f; In the previous case, the V11 force had to be transferred each time the casting taken out from the sand VI mold was subjected to the sand iS treatment or when moving from the sand removal treatment to separation and burial, and a series of In view of this problem, the purpose of the present invention is to separate the castings taken out from the sand mold from the sand dropper without transferring the castings. The object of the present invention is to provide a casting processing device that can carry out a series of processes up to sorting, thereby increasing the efficiency of the process. (Means for solving the problems) Above. In order to achieve the object, the solution of the present invention is to provide an unloading station at a predetermined position of the pouring line where the sand mold after pouring is conveyed with the top layer removed, and to the unloading station, On one side of the pouring line, there is a take-out station!, a point ↓ (a sand removal station, a product molecule IJ station d3, and a waste material collection station are arranged in order in a ring shape, and the station is circulated above each station). ) Set up a movable unit 1-.

[
On the other hand, a plurality of (f! lock clamp devices) are installed in the oT moving unit 1-5 so that they can be moved up and down.Meanwhile, a sand removal device is installed at the sand removal station to remove sand adhering to the castings, and a sand removal device is installed at the sand removal station to separate the products. The station is equipped with a product separation device that separates product feces from the waste parts such as the casting 1) + 13 sprue, and the waste collection station is equipped with a waste collection device that collects the waste parts of the casting. 47. Hold the sprue of the casting with the clamp device and take out the casting from the sand mold, and transport the casting sequentially to the sand drop station, product separation station, and waste material collection station while the sprue is clamped. It is something that has been completed. (Function) With the above configuration, in the present invention, the castings taken out from the sand mold by the molten rock clamping device are sequentially transferred to the sand removal station, product separation station, and waste material collection station while holding the castings in place. Therefore, at the sand removal station, the sand adhering to the PF material is removed by the sand removal device, at the product separation station, the product parts excluding the waste material are separated and collected from the casting by the product separation device, and at the waste material collection station, the waste material is collected. The waste material of the patterned material is collected by the device. (Example) An example of the present invention will be described below based on the drawings. Figures 1 to 3 show an example of the present invention. 7 casting duck 1!l equipment A is shown, and this casting processing equipment A is ?, 1
