Benefits of technology
This configuration enhances productivity by eliminating the need for uncoupling and coupling actions, allowing for efficient core sand distribution and packing, thereby improving overall core manufacturing efficiency.
Problems solved by technology
Since this core manufacturing apparatus ejects kneaded sand in a horizontal direction while the kneading vessel is in the horizontally lying state, it is difficult to pack the kneaded sand to the far corners of a mold.
However, this configuration has the disadvantage of poor core productivity due to the time taken for uncoupling and coupling actions.

Embodiment Construction
[0023]A specific embodiment to which the present disclosure is applied will be described in detail below with reference to the drawings. It is not intended that the present disclosure is limited to the following embodiment. To clarify the illustration, the following description and drawings are simplified as necessary.
[0024]Overall Configuration and Actions of Core Manufacturing Apparatus
[0025]First, the overall configuration and actions of a core manufacturing apparatus according to the embodiment will be described with reference to FIG. 1. FIG. 1 is side views showing the actions of the core manufacturing apparatus according to the embodiment. It should be understood that the right-handed xyz-orthogonal coordinate system shown in FIG. 1 and the other drawings is for the convenience of illustrating the positional relationship among components. Normally, a z-axis positive direction is a vertically upward direction and an xy-plane is a horizontal plane, which applies to all the drawi...

Provided is a core manufacturing apparatus including: a storage unit configured to store core sand; a kneading vessel configured to be fed with the core sand; a kneading rod configured to knead the core sand; and a piston configured to eject the kneaded core sand. The kneading vessel is capable of transitioning between a horizontally lying state and a vertically standing state and configured to be fed with the core sand in the horizontally lying state. The piston is configured to eject and pack the core sand into a mold with the kneading vessel in the vertically standing state. The storage unit is turnably coupled to the kneading vessel and configured to remain coupled to the kneading vessel in the same posture while the kneading vessel turns.
Description
INCORPORATION BY REFERENCE[0001]The disclosure of Japanese Patent Application No. 2019-228940 filed on Dec. 19, 2019 including the specification, drawings and abstract is incorporated herein by reference in its entirety.BACKGROUND1. Technical Field[0002]The present disclosure relates to a core manufacturing apparatus.2. Description of Related Art[0003]There are known core manufacturing apparatuses that manufacture cores by kneading core sand along with a binder etc. in a kneading vessel and ejecting and packing the kneaded core sand (kneaded sand) into a mold. A core manufacturing apparatus developed by the present inventors kneads core sand with the kneading vessel in a horizontally lying state, as disclosed in Japanese Patent Application Publication No. 2017-131913 (JP 2017-131913 A). Since this core manufacturing apparatus ejects kneaded sand in a horizontal direction while the kneading vessel is in the horizontally lying state, it is difficult to pack the kneaded sand to the far...
