Description

TECHNICAL FIELD

[0001] The utility model relates to a steel rolling production line equipment field, concretely relates to a steel rolling production line transfer chain has steel detection device. BACKGROUND

[0002] The inspection bench area is mainly composed of three sections of transfer chains and a counter, and is responsible for counting the number of finished bars. Due to the fast rolling rhythm and diversified rolling varieties of the production line, the finished products need to be quickly and accurately moved to the inspection area for steel bar counting. The main function of this device is to effectively detect the finished steel in the transfer chain area, ensuring that the transfer chain can accurately move the finished products to the counting station for steel bar counting.

[0003] The inspection bench area input roller conveys the finished steel to the level position with the first section of chain, and the flat support device supports the steel on the first section of chain. The first section of chain moves a certain distance to clear the entrance, waiting for the next batch of steel. When the first section of chain is full of finished steel, the second section of chain starts to run. When the finished steel is transferred to the second section of chain steel detection device area, the third section of chain starts to move the steel. When the steel passes through the counting area installed in the middle position of the third section of chain, the steel bar counting is performed. When the counting reaches the set number, the three sections of chain are stopped at the same time, and the steel is separated. Since the running distance of the first and second sections of chain is calculated by using the encoder feedback data, a certain cumulative error is easy to occur, causing the accumulation of finished steel. Therefore, a steel detection device is installed at the tail of the second section of chain to accurately detect whether the finished steel has arrived, so as to accurately control the start and stop of the third section of chain.

[0004] The original steel detection device uses a diffuse reflection photoelectric switch. During use, the diffuse reflection photoelectric switch is easy to be damaged by high temperature, causing large spare part loss. At the same time, when the signal is abnormal, the steel is easy to accumulate on the third section of chain, causing certain difficulties in steel bar counting and separation. In addition, the finished steel rubs through the detection mechanism, causing large wear of the mechanism, short service life, and the need for re-welding or replacement of the detection mechanism after a period of time. Therefore, the present application provides a steel rolling production line transfer chain steel detection device to improve such problems. UTILITY MODEL CONTENTS
