Box conveyer and foundry production system

Abstract

The invention discloses a box conveyer. The box conveyer comprises a rack, a moving trolley and a driving part, wherein a guide rail is arranged on the rack; the moving trolley can be arranged on the rack in a sliding manner along the guide rail; pushing heads are arranged on the moving trolley and used for pushing sand boxes; the driving part is arranged on the rack and used for driving the moving trolley to reciprocate along the guide rail. In the box conveyer, the pushing heads reciprocate along with the moving trolley, so that pushing of the sand boxes can be repeated. Obviously, the box conveyer can independently convey one or more sand boxes and avoids the situation that the sand boxes are conveyed one by one in a jacking manner on the whole foundry production line, so that the influence on the precision in conveying the sand boxes to a station from thermal expansion and cold contraction is reduced or even avoided to be conductive to operating the sand boxes at the station. The invention further discloses a foundry production system which employs the box conveyer, and the sand boxes can be accurately positioned on the station after being conveyed by the box conveyer, so that convenience is brought for a user to implement operations at the station.

Description

technical field [0001] The present invention relates to the technical field of machinery industry, more specifically, to a box feeder, and also to a casting production system using the above box feeder. Background technique [0002] There are many stations for different processes on the casting production line, each station is connected to each other through the roller table, the sand boxes are distributed on the roller table during production, and each sand box is offset in turn, and the sand boxes on the entire production line are used by the latter during transportation. The sand box is conveyed by sliding along the roller table against the previous sand box. [0003] However, the number of sand boxes on the casting production line is large, and each sand box has a large size difference under the action of thermal expansion and cold contraction. After the expansion or cold contraction of multiple successively offset sand boxes is superimposed, it is difficult to transport...

Problems solved by technology

[0003] However, the number of sand boxes on the casting production line is large, and each sand box has a large size difference under the action of thermal expansion and cold contraction. After the expansion or cold contraction of multiple successively offset sand boxes is superimposed, it is difficult to transport the sand boxes by the above method. Accurate positioning on the station, without operating the sand box on the station

[0004] In addition, the processes completed by each station on the casting production line are different, and the process at some key stations takes a long time, but the sand boxes of the entire production line are transported one by one above the other, resulting in the rapid completion of process operations. The station needs to wait for the process at the above key station to be completed before the sand box can be transported and the process operation for the next sand box can be carried out again
