Kebutuhan manusia semakin lama semakin meningkat, berkembang dan bervariasi, untuk memenuhi kebutuhan tersebut industri membutuhkan suatu alat yang dapat mengontrol dan mengendalikan proses permesinan secara otomatis. Diantaranya industri yang memerlukan pengendalian kualitas secara otomatis adalah industri makanan dan minuman instan. Di Indonesia, industri minuman didominasi oleh hasil olahan minuman instan bubuk dan cair. Salah satunya minuman instan kopi, minuman kopi membutuhkan beberapa tahap pengolahan, salah satu yang terpenting adalah proses pemutuan biji kopi. Saat ini industri masih menggunakan tenaga konvensional yang memakan waktu, biaya, tenaga operator. Penentuan mutu dengan cara seperti ini mempunyai kelemahan dari sisi subyektivitas yang memungkinkan terjadinya kesalahan akibat kelelahan mata manusia terhadap contoh yang dianalisis. Untuk menanggulangi masalah tersebut perlu adanya mesin pemutuan biji kopi dengan sistem otomasi berdasarkan parameter besar dan kecilnya biji kopi. Dengan cara menghitung banyaknya biji kopi pada sampel 300 gram biji kopi. Penyelesaian rancang bangun ini dilakukan dengan 2 tahapan yaitu perancangan konveyor sabuk dan perancangan otomasi. Perancangan konveyor sabuk pemilah terdiri dari pemilihan konsep, desain rinci menggunakan aplikasi Solidwork dan proses pembuatan berdasarkan desain. Selanjutnya, perancangan otomasi menggunakan mikrokontroller Arduino Uno, sensor load cell dan sensor FC-51. Setelah peralatan sudah dipasang semua selanjutnya dilakukan pengujian didapatkan dari 300 gram biji kopi terhitung jumlah biji kopi yang bervariasi yaitu 907, 954, 976, 1007, dan 1036 biji kopi. Kemudian, ketinggian sensor yang optimal 6 cm dari permukaan belt conveyor dan kecepatan conveyor 1,52 m/menit agar pembacaan sensor FC-51 akurat.

In this paper we consider the structural and technological process of the combine used in the process of separate harvesting of grain crops, as well as a number of its parameters. Among the main units of the combine, we allocate a conveyor and devices for removing beveled stems from under the wheels of the vehicle. The principle of operation of the conveyor at different phases of the Reaper and especially the removal of cut stems from under the wheels of the vehicle during operation of the Reaper. The results of theoretical studies on the establishment of the optimal design of the parameters of the belt conveyor are presented, the ranges of their optimal values are considered and determined. Studies on the establishment of optimal parameters of the screw divider in the Reaper, which is the main component of the device for removal of beveled stems, are presented. Taking into account the optimal design and mode of operation of the screw divider, the correct work is provided to remove the cut stems from under the wheels of the harvester.

To address deficiencies in the process of fault diagnosis of belt conveyor, this study uses a BP neural network algorithm combined with fuzzy theory to provide an intelligent fault diagnosis method for belt conveyor and to establish a BP neural network fault diagnosis model with a predictive function. Matlab is used to simulate the fuzzy BP neural network fault diagnosis of the belt conveyor. Results show that the fuzzy neural network can filter out unnecessary information; save time and space; and improve the fault diagnosis recognition, classification, and fault location capabilities of belt conveyor. The proposed model has high practical value for engineering.

Based on air cushion belt conveyor, a new type of belt conveyor named water cushion belt conveyor is proposed. It has a wide scope of applications for its features such as stability and reliability, capability of full load start-up, and environment-friendliness. This paper studies the working mechanism and lubricating mechanism of the water cushion belt conveyor. The basic lubrication equation of the water cushion is deduced from the universal form of the Reynolds equation used to study the pressure film properties of the water cushion. The design of the key part of the water cushion device is described in details. The research can be taken as a reference in practical applications.

OPC has been widely applied to coal mine automation control system as an industry standard of communication between the field control substation and PC in the control system. In this paper, through the analysis and design for the transport system of coal mine belt conveyor, communication between the PC and S7-300 PLC is realized by using OPC technology. This paper gives the configuration scheme of OPC Server and develops the OPC Client program. The actual operation shows that the system is stable, reliable of communication and high of data real-time.
