因にもなる。2. Description of the Related Art Conventionally, in a food production conveyor line or the like in which a toothed belt is driven by meshing with a toothed pulley to convey articles such as confectionery on the toothed belt surface, powder of confectionery dough is used. In some cases, crumbs after baking are mixed in and intervene in the tooth spaces between the toothed belt and the toothed pulley. If foreign matter such as broken scraps is particularly hardened in continuous operation while staying in the tooth groove on the pulley side, poor meshing occurs with teeth on the toothed belt side, causing so-called "tooth skipping" of the teeth on the toothed belt. Occur. When the tooth jump occurs, the belt itself vibrates due to the impact when returning to the pulley side, which may cause inconvenience such as the conveyed article on the belt dancing and dropping.

中央を高く所要の曲率で円弧状に成形したものである。A conveyor toothed belt according to the present invention requires a tooth provided on a main body to have a high center in a tooth thickness direction when an article is conveyed by an operation by meshing with the toothed belt. It is formed into an arc shape with a curvature.

を防ぐ。[Function] Since the teeth are formed in an arc shape so as to have a middle height in the tooth thickness direction, foreign matter staying in the tooth groove on the toothed pulley side is inclined especially during operation by meshing with the toothed belt. Naturally eliminated along the surface. In addition, since the teeth are middle and high, the toothed belt is moved to the center during operation to prevent lateral displacement.

The main body 10 has a tooth 1 having a tooth profile with a predetermined module and pitch.
1 is provided, and the tooth 11 is formed in a so-called crown shape whose center is higher in the tooth thickness direction indicated by reference numeral t.
That is, the tooth 11 having the tooth thickness t has both a tooth tip 12 and a tooth root 13 which form a gentle arc from one side to the other side with the same curvature r and are pressed or machined with a convex cross section.

かに排除される。Therefore, in the toothed pulley of the embodiment, during operation by meshing with the toothed belt, foreign matters such as broken dust generated from articles being conveyed by the toothed belt, especially the teeth 11 on the pulley side.
Even if it stays in the tooth space between the tooth tip 12 and the tooth root 13, it slides down to both sides in the tooth thickness direction along the aspect of the middle-high arc. In this way, the foreign matter staying in the tooth space is promptly removed without accumulating.

し出す機能をも持ち合わす。Further, since the teeth 11 of the toothed pulley are formed in a crown shape, a force for moving the toothed belt in operation toward the center of the tooth thickness t acts, and the toothed belt is laterally displaced from the toothed pulley. Can be prevented. Even if it is difficult to remove foreign matter from the tooth groove on the pulley side, the centering action of the toothed belt is due to the repulsive force generated when the toothed belt is moved to the center in the tooth thickness direction during operation. It also has a function of forcibly sliding off foreign matter that tends to stay on a curved surface and pushing it out of the pulley body 10.

中央寄せ機能が得られて横ズレを防ぐことができる。As described above, in the toothed pulley for conveyance according to the present invention, the tooth profile is formed in a circular arc shape having a high center in the tooth thickness direction, so that the toothed belt can be operated during meshing operation with the toothed belt. In particular, foreign matter generated from conveyed articles does not stay in the tooth space on the pulley side and is quickly and naturally removed.
It is possible to prevent tooth jumping on the toothed belt side. Also,
At the same time, by setting the tooth profile in the shape of a middle-high arc, the centering function of the toothed belt can be obtained and lateral displacement can be prevented.
