Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF THE INVENTION The present invention relates to hanging conveyance equipment employed, for example, in an internal combustion engine assembly factory, when internal combustion engines are conveyed sequentially to a plurality of work stations.

Conventional technology and its problems For example, as shown in Fig. 4, the fixed path 4 of the suspended conveyance device is formed at right angles to (along the obstacles) avoiding obstacles such as walls and various devices. At this time, the curved path portion (c) is formed to have a sufficient (large) radius of curvature to allow the trolley device (c) to move smoothly. Therefore, a crowded dead space is created outside the curved route section. Work station 4 to make effective use of this dead space.
It is conceivable that a trolley device (431) is provided in the curved path section i42 as shown by the imaginary line, and the trolley device (431) is stopped to carry out each of the hoisting operations on the objects to be conveyed via this trolley device Aj. However, it is difficult to position the trolley device 141 that is stopped on the curved path (c), and therefore the intended work cannot be performed accurately.
As shown in the figure, a method was proposed in which a trolley device (railway) was stopped at the end of the straight path section just before entering the curved path section (■), but according to this, the work station (A) would come out of the dead space (B). The straight path section below the curved path section 42 is an obstacle 141).
Since it has to be returned to the predetermined position with respect to K,
The curved route portion will have a complicated shape, and the curved route portion will be too close to the obstacle (c). As another conventional example, as shown in FIG.
A configuration with a turn tape /I/I4η having 61 is proposed. However, according to this conventional example, the work station is υ, and the trolley device (c) that supports the conveyed object that is not subjected to work must also be transferred to the turntable lumi 4η side once, and this work station 75760 You will want to be able to quickly pass through the sections. For this purpose, a bypass route (C) is provided as shown by the imaginary line, and those that do not receive work at the work station body are provided with the bypass route (4).
81, but this requires a space inside the fixed route frame to arrange the bypass route i4s.
