However, such a conveyor belt has protruding portions on the conveying surface, so that the traveling vibration and traveling resistance when wheels such as work carts are grounded and rolled are large, and an excessive traveling load is imposed. There was a problem.
Also, when trying to design a high-density transport surface by closing the gaps in the pitch direction of the chain modules, the back bend radius on the inner circumference side of the belt due to the influence of contact failure of adjacent convex parts between the chain modules Since the intermediate idle roller and the like must be appropriately disposed, it is difficult to secure an appropriate belt slack on the belt return side.

  Therefore, the present invention solves the above-described problem, that is, the object of the present invention is to reliably slide an operator or a work carriage in a work area along an article production line, an assembly line, or the like. It is easy to transfer the work carriage by stopping the vibration and running resistance that tends to occur on the wheels of the work carriage and avoiding contact between the object support ribs between the chain modules. It is an object of the present invention to provide a work path conveyor chain that achieves downsizing and simplification of the conveyor by reducing the peripheral back bend radius.

  In order to achieve the above object, the invention according to claim 1 is configured by connecting a number of synthetic resin chain modules having anti-slip mounting surfaces of workers and work carts by connecting pins, and manufacturing articles. In a work path conveyor chain equipped with workers or work carts working in a work area along a line or assembly line, the chain modules are formed on the front and rear edges in the longitudinal direction of the connection, and through the connection pins And a module main body having a non-slip mounting surface formed between the front and rear of the hinge and being flush with the hinge. The non-slip mounting surface is assembled with a number of objective support ribs that protrude from the base surface with the anti-slip mounting surface carved inward so that it is flush with the anti-slip mounting surface. It is by provided to avoid contact between the objective supporting ribs in mutual pitch direction of the chain module is intended to solve the problems described above.

  In addition to the configuration of the invention according to claim 1, the work path conveyor chain of the invention according to claim 2 has a sawtooth-like cross-sectional shape of the objective support rib. Further solving the above-mentioned problems.

  In addition to the configuration of the invention according to claim 1 or 2, the work path conveyor chain according to the invention according to claim 3 has a number of objective supports that assemble the non-slip mounting surfaces of the chain module.

In addition to being able to mount workers and work carts working in a work area along the line, etc., the following specific effects can be achieved.

In other words, the work path conveyor chain according to the first aspect of the present invention has a number of objectives in which the non-slip mounting surface of the module body protrudes from the base surface in which the anti-slip mounting surface is carved inward. Because the support ribs gather together, the safety shoes worn by the workers and the wheels of the work carts and other rubber bottoms, such as the wheels, touch the ground while deforming into many objective support ribs. A reliable anti-slip function for workers and work carts.
In addition, since a large number of objective support ribs are provided so as to be flush with the anti-slip mounting surface, it is possible to reduce running vibration and running resistance that tend to occur when the wheels of the work carriage roll on the ground. Since the restraint is greatly suppressed, the movement of the work carriage can be easily achieved.

  And, the non-slip mounting surface of the module main body is protruded so as to be flush with the anti-slip mounting surface from the base surface of the module main body in which the anti-slip mounting surface is carved inward. A large number of chain modules are packed together with the objective support ribs so as to avoid contact between the objective support ribs in the pitch direction of the chain modules so as to close the gaps in the pitch direction of the chain modules. Since it is possible to avoid contact between the object support ribs between the chain modules when designing a transport surface laid with high density, the back bend radius on the inner circumference side of the belt can be reduced to reduce the size and simplify the conveyor. Can be achieved.

  Further, in addition to the effect of the invention according to the first aspect, the work path conveyor chain according to the second aspect of the invention has a sawtooth shape in the cross section of the objective support rib. Since the rubber bottoms such as safety shoes and work cart wheels worn by the person are deformed and deformed into a large number of objective support ribs assembled to the grounded position, it is further improved for the work person and work cart Secure anti-slip can be realized.

  In addition to the effect of the invention according to claim 1 or 2, the work path conveyor chain according to claim 3 of the present invention has a large number of objective support ribs for assembling the non-slip mounting surface of the chain module. However, it is arranged to present a combination pattern consisting of a large number of hexagonal shapes and rhombus shapes, so that the workers and work carts can be reliably prevented from slipping in any direction. can do.

Sectional drawing seen from the AA line of the chain module shown in FIG. 1, and its partially expanded view. The usage aspect figure of the conveyor chain for work paths which concerns on a present Example.

  In the work path conveyor chain of the present invention, a number of synthetic resin chain modules having anti-slip mounting surfaces for workers and work carts are connected by connecting pins, and the anti-slip mounting surfaces of the chain modules are slipped. The pitch direction of the chain module is assembled by a number of objective support ribs that protrude from the base surface with the stop mounting surface engraved to be flush with the anti-slip mounting surface to prevent the operator and work carriage from slipping. It is laid so as to avoid contact between the objective support ribs between each other, and it is easy to transfer the work carriage by reliably preventing the operator and the work carriage from slipping. If it is possible to reduce the back bend radius on the belt inner circumference side by avoiding the contact of the belt to achieve downsizing and simplification of the conveyor Specific embodiments of implementations no problem be any one.

  In other words, the synthetic resin material of the chain module used in the present invention is not limited as long as it can be molded at least and exhibits sufficient toughness and shape retention sufficient to mount an operator or work carriage. For example, polyethylene Resin, polypropylene resin, engineering plastic resin such as acetal resin, or reinforced resin in which reinforcing fibers such as glass fibers are contained in these resins may be used.

The shape of the chain module used in the present invention is such that a number of objective support ribs are assembled so that they are flush with the anti-slip mounting surface in a state where the anti-slip mounting surface is engraved, and the chain modules are arranged in the pitch direction. As long as it is laid so as to avoid contact between the objective support ribs, the “engraved state” in the present invention refers to the inside of the chain module, that is, the non-slip mounting surface. This means that the molding part is relatively projected by recessing the outer periphery of the modeling part inward, and if the modeling part can be formed, the processing means is molding processing, etc. Any of these may be used.
In addition, more specifically, a large number of hinge parts for connecting the connecting pins as disclosed in Japanese Patent Application Laid-Open No. 2006-111449 described above and connecting each other in a finger-set shape are connected in the connecting longitudinal direction. Needless to say, they are formed on the front and rear edges.
