Abstract

In order to determine the theoretical minimum clamping pressure required in carton clamp handling of heavyweight corrugated package (HCP) such as large packages or unitized agricultural product packages, a numerical model of clamping pressure was developed. To develop the model, the dynamic load factor was measured at the handling test course which was designed on the basis of actual handling environment of the target HCP. Also, the static-frictional coefficients between the HCPs and between the HCP and a rubber contact pad of carton clamp arm were analyzed. The main factors in the developed numerical model of clamping pressure were the handling load weight and the effective contact area of the carton clamp arm. In addition, field tests were performed to validate the theoretical minimum clamping pressure calculated from the model. Averaged slip distance from the single package and two packages handling was estimated as a 3.2 mm through field test, and it is expected that the 3.2 mm slip distance will be acceptable for a safe operation in the handling environment. The suggested analytical approach with the numerical model can be a useful means for estimating the clamping pressure of the carton clamps used to handle the HCP.

Highlights

Transport packaging is increasingly considered to be a critical component to promote the efficiency of the entire logistics process such as transport, inventory, warehousing and communication[1,2,3]
2.1 Static-frictional coefficients The static-frictional coefficients between the outer liners of the corrugated paperboard and between the outer liner and a rubber contact pad of the carton clamp arm were measured. Both the machine direction (MD) and cross-machine direction (CD) of the outer liners were used as sample materials, and these samples are separated with three different materials which are commonly used in South Korea as the outer liners of corrugated paperboard

Summary

Introduction

Transport packaging is increasingly considered to be a critical component to promote the efficiency of the entire logistics process such as transport, inventory, warehousing and communication[1,2,3]. The transport packaging can be importantly considered to reduce the loss of agricultural products during the transport process[4,5,6]. It needs to efficiently interact with materials handling environment during the logistics process[7,8]. The main advantage of carton clamp is pallet-less loads handling That is, it enables the handling of various loads, such as home appliances and packaged food or agricultural products without the need for a pallet or skid[9,10]. Carton clamp has limitations when considered from a holistic
