To this end, the FRAME BODY material is made of iron FRAME BODY, the FRAME BODY is formed by the roll-perm method, and the roller shaft of the PLASTIC WHEEL CONVEYOR MODULES and FRAME BODY Provides a plastic wheel conveyor module and a method of manufacturing the roller guide which can be rotated by contacting plastic and metal by inserting roller guide in the middle of hole.

Description

The process of Plastic Wheel Conveyor Module with more to bear heavy load and low pitched sound (in low-price)}

1. Roll-Firming Technology Considering Plasticity of Steel Sheets:

The roller guide rail is made by bending the frame body of the plastic wheel conveyor module to the inside with the roll-perm machine at right angles.

2. Dimensional change prevention technology due to shrinkage of resin

The guides are made horizontally on the roller-guide to prevent dimensional changes due to shrinkage, and the sliding guides are embossed on the rails of the frame body on both guide tops to facilitate the insertion of the roller guides on the frame body, and to prevent shaking after assembly.

3. Using the roll-perm machine to prevent cracking of the material due to the plastic change, roll plate is used to prevent the separation of the roller guide shaft and roller in the frame of secondary banding technology PLASTIC WHEEL CONVEYOR MODULES Bending two times with a firming machine to hold both guides of the roller guide

4. Shape design and gate position and size setting technology to prevent warping

7 rollers can be assembled on the roll guide, but the proper thickness guarantee and gate setting minimize the resistance of the resin to the mold to reduce shear stress and prevent distortion.

The present invention is a roller shaft connected for rotation of the roller according to the movement of the load on the PLASTIC WHEEL CONVEYOR MODULES is inserted directly into the FRAME BODY HOLE of the PLASTIC WHEEL CONVEYOR MODULES. Minimizes

To reduce the FRAME BODY deformation caused by the load on the rollers, the FRAME BODY material was improved from AL FRAME BODY to GI FRAME BODY, and the FRAME BODY was changed from extrusion to roll-perm to FLEXIBLE PIPE RACK SYSTEM Improve the production of PLASTIC WHEEL CONVEYOR MODULES and manufacturing methods.

1.Reduce noise in PLASTIC WHEEL CONVEYOR MODULES

2. PLASTIC WHEEL CONVEYOR MODULES Improved by FRAME BODY material in order to prevent deformation due to the load applied, and distributes the load on FRAME BODY

3. Development of low-end products that can reduce processes and reduce prices by improving manufacturing methods

1.The roller shaft 130 connected for rotation of the roller 140 according to the movement of the load on the PLASTIC WHEEL CONVEYOR MODULES is inserted directly into the frame body hole 14a of the PLASTIC WHEEL CONVEYOR MODULES and rotates with the roller shaft 130 when rotating. In order to minimize friction noise caused by metal surface contact between the frame body holes 14a, the roller shaft 330 is inserted into the roller roller guide 320 made of resin, and the metal shafts are inserted into the frame body hole 310c again. Eliminates rotary contact

2. Change AL which is progressively deformed by load into iron (GI) material and piercing-hole 14a on the bottom surface 310a of the frame body 310 and the piercing-groove 12a on the side surface 330b. By dividing it into 3 types, A-TYPE which distributes weight of light weight and B-TYPE which has piercing-groove 12a only on the bottom surface 310a, and C-TYPE without piercing-groove.

3. The integrated roller-guide 320 reduces the number of labors and improves the insertion of the holes 220c into the grooves 320c to prevent noise from occurring on both side wall surfaces 110b of the main frame. Cost structure by mass-producing roll-forming machine through material improvement

1. Insert the roller shaft 330 into the roller-guide 320 and insert it into the FRAME BODY groove 310c to eliminate the rotational contact between the metal faces to reduce the coefficient of friction, thereby suppressing the noise generation. The noise generated when the load 20kg rolls on the 6 degree slope is 40db or less

2. The main frame 310 of the main frame 310 according to the distribution load by changing the material of the main frame 310 having a lower bottom surface (310a) and both side wall surfaces (310d) and guide grooves formed along the inner longitudinal direction to iron (GI) material. The load concentrated on the shaft 330 is changed by changing the roller guide 320 inserted into the guide groove 310c formed along the inner surface of the main frame 310 from the detachable to the integrated roller-guide to prevent progressive deformation. Oler-guide (320) to partially distribute the load of the base distribution load is increased from 170kgf / m to 220kg.f / m, the concentrated load is increased to 150 kgf / roll at the maximum 100kgf / roll

3. Insert the roller 340 into the shaft 330 through the integrated roller and then insert it into one plastic frame 320b, and insert the plastic frame into the shaft in the opposite direction and insert it into the guide groove formed along the inner side of the main-frame. Three steps of inserting process are made in two steps, and it has the effect of simplifying the process by reducing the separation phenomenon due to the one-piece type, and improves the mass productivity by developing the maniframe manufacturing method by the roll-perming method.

1. Review:

end. Easy to assemble and load should be evenly distributed

I. Must not be dislodged and must not come in contact with 100% shaft and main-frame

All. Must be mass-producible and reduce manufacturing costs

2. Investment section:

end. Roller guide (320), roller injection mold production

I. Dedicated roll-firming machine, punching mold making, etc.

3. Review and improvement contents at design time

end. Compensation for workability and separation problem due to separate roller type

I. Ease of workability and search for load distribution methods --- 1 roller-7 assembly per guide

All. Sharpening of the main-frame side causes roller damage and progressive noise --- Banding the roller contact with the side of the mainframe eliminates sharp parts

la. Noise is generated by contacting the main frame with the shaft play in the roller-guide side frame hole area.-Make a groove so that the shaft does not touch the roller-guide side part.

end. Scope of application: Used in places where low noise and friction generate less dust

I. Areas of application: storage of semiconductor components-racks, transport trolleys, transport trolleys for indoor work spaces such as various tests / practice, storage racks-racks, storage racks for low noise in hospitals and special places-racks
