Pallet Supply Frame Layout for Hoist-Free Controller Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of conventional pallet conveyance apparatuses is difficult in plants without hoisting devices like overhead cranes due to poor braking performance and the need for precise positioning, leading to lengthy installation times.
Innovation Solution
A pallet supply apparatus with a frame design that allows the controller to be installed without a hoisting device, featuring a cover that flips up to accommodate the controller, enabling easy assembly and alignment of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the controller is installed inside the frame of the pallet storage device, then the space for the whole apparatus is saved, but the installation becomes very difficult in plants without hoisting devices
Solution Approach 1:
The frame is divided into an upper frame and a lower frame that can be assembled separately. The controller is installed on the lower frame first, then the upper frame is attached to complete the assembly. This segmentation allows installation without hoisting devices while maintaining the compact integrated design.
Solution Approach 2:
The controller is preliminarily installed on the lower frame before the upper frame is attached. This preliminary action allows the controller to be positioned and secured easily without requiring overhead lifting equipment, as the installation is performed from below.
2Ease of manufacture
If the pallet storage is lifted by means of a hoisting device, then the controller and pallet storage can be installed, but the installation time becomes very long due to poor braking performance and swinging
Solution Approach 1:
The frame is segmented into upper and lower parts that can be assembled on the ground without lifting the entire pallet storage. This eliminates the need for hoisting devices and associated timing issues with braking and positioning.
Solution Approach 2:
Components are preliminarily assembled and positioned on the lower frame before final assembly. This preliminary ground-based assembly eliminates the time-consuming overhead lifting and precise positioning operations.
3Ease of manufacture
If a crane vehicle is used instead of an overhead crane, then installation is possible, but accurate fine positioning becomes difficult
Solution Approach 1:
The frame is divided into upper and lower sections that can be assembled separately on the ground. This segmentation eliminates the need for crane-based positioning, as the smaller components can be precisely aligned and assembled at ground level without requiring overhead lifting precision.

AI summary
The present invention includes a pallet storage device (30) having holding units (31, 32, 33) holding pallets (P) and a frame (40) supporting the holding units (31, 32, 33), a conveyance device (10) having a traveling base (11) having a traveling path (11a) extending along the pallet storage device (30) and a conveyance unit (15) loading and unloading the pallets (P) into and from the holding units (31, 32, 33) and conveying the pallets (P) to and from a predetermined place, and a controller (60) controlling operation of the conveyance device (10). The frame (40) has a space capable of receiving the controller (60) therein and has a plate-shaped cover (43, 48, 51) arranged to be located above the controller (60) and inclined downward toward the traveling base (11) side. The cover (43, 48, 51) is supported by the frame (40) such that a lower end of the cover (43, 48, 51) can be flipped up, and the cover (40) is configured such that the controller (60) can pass under the cover (43, 48, 51) when the lower end of the cover (43, 48, 51) is in a flipped-up state.
