Heavy Duty Steel Ball Transfer Conveyor Table

Katrangan

The ball transfer table is a special conveyor plate. Because there are many ball transfer rollers on it at a certain desity. And these ball transfer units not only have bearing capacity, but also can roll flexiblely. Mula, objects such as work boards and material bins can slide very flexibly. Therefore it greatly reduces the labor intensity of workers. According to different load requirements, it can set the distribution density of the ball transfer rollers arbitrarily. Mesthi wae, it can also choose ball rollers with different carrying capacity. There are light duty and heavy duty ball transfer tables.

Due to the flexible and diverse structure, ball transfer conveyor is used in many occasions, such as transportation, transition, ngowahi, lsp. Ball conveyor is suitable for conveying items with flat and smooth bottom surface, for example pallets. But it is not suitable for the transportation of uneven bottom surface (for instance ordinary turnover box) and soft bottom (such as cloth parcels).

How do ball transfer units work? or how does ball conveyor work?

The basic conveying principle of ball transfer unit is unpowered conveying by using ball motion. Mula, the object can move at will on the ball. Below is the structure of a ball transfer roller.

Sepisanan, the outermost part is the outer casing. And the shell is nested with transfer ball. Banjur, the transfer ball makes point contact with the small balls. The small balls are nested in the upper part of the lifting blocks. Pungkasane, the lifting blocks is connected with the inner wall of the bottom of the housing through the springs below.

When conveying items, the transfer balls are under pressure. Sanalika, the lifting block presses the springs to compress. So the transfer ball is retracted into the housing. But the ball can still ensure the normal rotation of the ball. After the object passes, the transfer ball returns to its original position due to the reaction force of the spring.

Material of ball transfer roller: waja karbon (galvanized), bearing steel (galvanized), Stainless steel SS304, SS404 stainless steel, nylon;
Countertop: made of steel plate bending or channel steel;
Legs: steel pipe or square tube. Ing tambahan, painting the frame surface.
The load-bearing capacity of each ball transfer unit: different specifications, different load-bearing, ranging from 2KG to 1200KG.

Contone, Before, we customized several ball transfer conveyor for a customer. The specification is L1400*W1400*H700mm. The following are the relevant specifications:

1. Bracket part: adopt 50*50*2T iron square through welding;
2. Table plate: made of T4mm iron plate. Salajengipun, welded reinforcing ribs at the bottom. Firnally, add SS201 stainless steel on the surface;
3. ball transfer rollers: flat-bottomed ball transfer unit with screw rod, and spacing is 100*100mm;
4. The height of ball transfer table is adjustable from 700~1000mm;
5. The surface of the iron parts needs painting, and the color is computer gray;
6. Processing quantity: 5 sets;

2. Load-bearing of ball roller conveyor:

The static load of ball transfer rollers is usually from 30-250KG/pc. So there are two kinds of ball transfer conveyors for choice. One is heavy duty ball transfer table. And another is light duty ball conveyor. If your application is for low load, you can choose the light duty ball transfer table. This ball conveyor table is usually made through a stamping process. Kosok baline, choose the heavy duty ball transfer conveyor. It’s usually manufactured by CNC precision lathe processing.

Kajaba iku, the load-bearing capacity of the ball conveyor is also related to the arrangement density of the ball transfer units. We can set the distribution density of the ball transfer rollers according to different load-bearing requirements. In order to ensure that the load surface remains on the ball transfer rollers without slipping, the distance between each ball transfer unit should be the minimum side length of the load surface divided by 2.5.

Second, the processing technology

Good processing technology determines the quality of the ball transfer units. The main production methods are stamping and CNC precision lathe finishing. After processing, it must check the appearance. And then it begin to undertake the next process—plating. In order to make it wear-resistant and corrosion-resistant, we need electroplating. Common types of electroplating are as follows, such as chrome plating, nickel plating, and zinc plating. After finish electroplating, we will check the electroplating pass rate. Sanalika sawise, it will assemble the ball transfer rollers. As we all know, the working principle of a ball transfer table and roller is the big ball rolling along with the small balls. The material of small balls is high-hardness bearing steel. So the service life and flexibility is better.

After finish assembly, it will check the mechanical parameters and flexibility of the ball transfer rollers. Determine whether the friction coefficient is lower than 0.05. If it is lower than 0.05, it is qualified. Kosok baline, if it is higher than 0.05, then it is not qualified.

Pungkasane, after finish inspection, we will do anti-rust treatment on the ball.

1. 1. Common installation methods of ball transfer units are as follows, such as self-tapping screws, rivets, bolts, drilling and pressing, DIN417 circlips, nuts and welding.

Sepisanan，”self tapping screw” lan “rivet” fit for light duty flanged type.
And then, “bolt” fits for heavy duty flanged type.
Kosok baline, “drilling and pressing” fits for none flange type.
Then the “DIN471 circlip” fits for none flange type with small sizes.
lan “nut” fits for bolt type;
Pungkasane, “welding” fits for carbon steel casing type.

2. After determin the installation method, distribute the ball transfer roller 3 evenly on the plate 1. On the ball transfer table conveyor, the distance between the balls is determined according to the load-bearing.

3. Sanalika sawise, make the 4pcs of support legs. And then install the legs 2 onto four corners of plate 1.

4. Pungkasane, install 4 universal wheels with brakes on the legs. Then the ball transfer table conveyor is produced.
