Full scale introduction of Logistics support robot CarriRo® AD at Sagawa Global Logistics Co., Ltd.

-Higher efficiency and Labor saving achieved in warehouse operations-

CarriRo® AD (Autonomous Moving Model), a logistic support robot of ZMP Inc. in Bunkyo-ku, Tokyo (CEO , Hisashi Taniguchi, hereinafter ZMP) which started to be in sale since November 2018 got introduced to Sagawa Global Logistics Co., Ltd. where its Head office in Tokyo Shinagawa-ku (President and CEO, Kotobayashi Morishita), which develops domestic logistics business in the SG Holding Group, aims to streamline and reduce labor in-house work by automating transportation work.In January 2019, CarriRo® AD was introduced to the East Kanto branch Kashiwa SRC (Kashiwa city, Chiba prefecture).

At the SRC Branch, in addition to save the manpower which has become a serious problem of the society, the frequency of traffic in warehouse is high due to the relationship between the operation and work content inside the warehouse. As a result, minimizing the travel time of workers becomes is one of the most important priority to be considered in order to improve the productivity.​ ​

In order to solve this problem, the company decided to introduce our CarriRo® AD, which can be able to automatically perform carry and picking packages up to 300kg. We also provided a variable landmark that can be changed each time by setting the travel route in advance as a pattern. The practical use of CarriRo® AD was verified by December, and we believe that the product will enhance the efficiency as well as flexibility of warehouse operation.​ ​

Our Company has examined and verified CarriRo® AD’s performance for a month and, we concluded that instead of loading packages on CarriRo® AD, the capacity would be increased if we use CarriRo® AD to tow cargo and transport more luggage. The transportation time for picking goods from the receiving area to shelves has recorded to reduce for 3 hours per day (approximately 4 kilometers) compared to the conventional method. CarriRo® AD has been fully introduced at Kashiwa SRC because it was confirmed that this would lead to significant efficiency and labor savings.

The company will continue to optimize resources by using advanced technologies to save resources and achieve optimal logistics designs for customers.

One cargo was carried by one person in conventional method. With the introduction of CarriRo® AD, two cargoes can be carried unmanned.

■Unmanned means of transportation:
1. Conveys goods that have been received and inspected to a storage location about 70 meters away.
2. Reverse route transport of empty containers from storage location to receiving area.

【Logistics Support Robot CarriRo®】
CarriRo® is a bogie type logistic support robot which is available in two different modes. The Autonomous Moving mode model and a Following model. The latter can be operated using a joystick to move in karugamo mode which automatically follows a beacon (transmitter). By using CarriRo®, it is possible to raise the transport productivity up to about 3 times. With CarriRo® alone you can carry baggage of up to 150 kg, CarriRo® with an optional tow jig can carry about 300 kg of baggage for 8 hours in a row, improving the efficiency of picking operations in warehouses and distribution centers. It is also possible to substitute a belt conveyor or AGV (automatic guided vehicle) by using it for inter-process conveyance in the factory. Moreover, since the work load is greatly reduced, it becomes possible for women and elderly people to carry out the transportation work which was regarded as hard labor so far, so it can be used for expanding workers and promoting employment.
