Title:
RECIPROCATION DEVICE
Document Type and Number:
Japanese Patent JP2022015172
Kind Code:
A
Abstract:
To provide a reciprocation device capable of surely moving a transportation object to a prescribed intermediate stopping position and positioning stably with inexpensive facility cost.SOLUTION: A reciprocation device has a rotary arm projectingly provided to a rotary driving shaft, a chain member connected to the rotary arm, and a holding body with a tip of the chain member connected thereto or with a shaft holding part of the rotary driving shaft attached thereto and holding a transportation object. The reciprocation device reciprocally moves the holding body by taking-up or rewinding the chain member by rotation of the rotary arm. The chain member has multiple link members, the rotary arm, each link member and the holding body are connected at rotatably connected connection parts, respectively, and each connection part has a rotation axis parallel to the rotary axis of the rotary driving shaft. At a prescribed rotary angle where the projection direction of the rotary arm from the rotary driving shaft is in parallel to the moving direction of the holding body, the rotary axis of the rotary driving shat and the rotary axis of each connection part are arranged on one plane parallel to the moving direction of the holding body.SELECTED DRAWING: Figure 1
