Description

[Detailed description of the invention] Blessings and advancement! The present invention relates to a bolt alignment device that sequentially distributes bolts continuously fed from a parts feeder into two rows and aligns a plurality of bolts at predetermined intervals.

Fox rice! For example, when assembling a cylinder block and a cylinder head in an engine assembly process, a cylinder head is usually provided on the cylinder block, and a connecting flange is formed on the upper peripheral edge of the cylinder block and the lower peripheral edge of the cylinder head, respectively. are placed one on top of the other through a gasket, a bolt is inserted into the bolt hole formed in the reconnection flange, and the inserted bolt is tightened to assemble.

Previously, workers had to manually insert the bolts, but 8 to 10 bolts are used to assemble each cylinder head and cylinder block, and the assembled cylinder heads, etc. Since the material was continuously sent over the top at a constant speed, the workers were forced to do hard labor, and the work efficiency was also poor.

Therefore, in order to improve the working conditions of workers and improve work efficiency, the applicant developed and proposed an alignment device that automatically aligns bolts [Japanese Patent Laid-Open No. 61-2410
See Publication No. 35].

As shown in Fig. 15, the above-referenced alignment device is, in principle, an alignment plate (2) in which a plurality of bolt holding grooves (1) (1), etc. are formed in the same arrangement as the bolt insertion holes of the cylinder head.
