Description

A conveyor system that automatically adjusts the spacing between IV bags and supplies {CONVEYOR SYSTEM THAT AUTOMATICALLY ADJUSTS PRODUCT SPACING}

The present invention relates to a conveyor system that adjusts the spacing between the IV bags to be uniformly widened during the transfer process of the IV bags. More specifically, during the transfer of the IV bags through the conveyor for smooth pickup of the IV bags that are crowded together. It is about a conveyor system that can uniformly widen the spacing between IV bags.

In general, product transport conveyors are widely used for transporting parts or materials at industrial sites, moving semi-finished products, transporting coal and ore cargo at ports and mines, and transporting sand at construction sites. They have an automation function and continuously transport materials. It is a device that moves an item a designed distance.

This product transfer conveyor serves as a workbench and helps users go through various processes according to the order, functioning as an essential device for mass production.

Conventional product transport conveyors are often belt-type conveyors or roller-type conveyors, and various types such as trolley-type conveyors and wheel-type conveyors are also used depending on the purpose of use.

The goods transport conveyor requires a power device to have transport capacity and may require a guide to send goods in a desired direction and distance.

In addition, the driving part of the conveyor is designed by connecting a motor and a mechanism capable of reciprocating movement, such as a belt or roller. The ability to transport goods is determined by the torque and rotation speed of the motor. The stronger the torque, the more weight the goods can be transported. It can be moved, and the faster the rotation speed, the more distance the goods can be transported in a short period of time.

These conventional belt-type conveyors or roller-type conveyors have limitations in controlling the speed or direction of conveying goods.

In the case of the belt-type conveyor, the entire belt is designed to rotate at a constant speed in conjunction with a motor, and since the multiple items loaded on the belt all move at one speed, they are used by a pickup device for box packaging of products. When picking up a product, if several products are gathered on the conveyor, problems may occur that prevent the product from being picked up smoothly.

In addition, if the spacing between products moving through the conveyor is manually adjusted so that they can be smoothly picked up by the pick-up device, there is a problem that not only does the production cost increase, but the production speed is reduced due to manual work.

Republic of Korea Patent Publication No. 10-2019-0014289 (published on February 12, 2019) Republic of Korea Patent Publication No. 10-2016-0039791 (published on April 12, 2016) Republic of Korea Patent No. 10-2129335 (announced on July 3, 2020) Republic of Korea Patent No. 10-2067634 (announced on January 17, 2020)

Therefore, the purpose of the present invention is to automatically adjacent to each other the IV bags, such as IV bags, which may be stacked or partially overlapped during the process of being transported through a conveyor, so that they can be smoothly picked up by the pickup device during the quality check process. The goal is to provide a conveyor system that adjusts the spacing between them.

In order to achieve the object of the present invention described above, in one embodiment of the present invention, an infusion conveyor for transporting a transfusion bag, a first sensor unit for generating sensing information by detecting an infusion bag passing through the infusion conveyor, and A distribution conveyor installed at the rear of the input conveyor to transport the IV bags that have passed through the input conveyor and adjusting the moving speed of the IV bags so that the IV bags that have passed through the input conveyor maintain a certain distance from each other according to the sensing information, and the distribution A transfer conveyor installed at the rear end of the conveyor to transfer the IV bag that has passed through the distribution conveyor, a second sensor unit that detects the IV bag that has passed through the transfer conveyor and generates sensing information, and a second sensor unit installed at the rear end of the transfer conveyor A shuttle conveyor that provides a seating surface for the IV bags that have passed through the transfer conveyor and adjusts the length of the conveyor belt so that the IV bags that have passed through the transfer conveyor are introduced at predetermined intervals, and distribution according to the sensing information collected from the first sensor unit. Controls the rotational speed of the conveyor, extends the tip of the shuttle conveyor in the direction of the transfer conveyor according to the sensing information collected from the second sensor unit, and when a predetermined number of sensing information is collected from the second sensor unit, the tip of the shuttle conveyor Provides a conveyor system including a control unit that rotates to the initial position.

According to the present invention, the front-to-back spacing between the IV bags can be adjusted during the process of transporting the IV bags through the conveyor so that the front and back spacing between the IV bags that are crowded together can naturally be maintained at a certain distance even if the transportation of products such as IV bags is not stopped. You can.

In addition, the present invention increases the production speed because the spacing between the IV bags can be automatically adjusted during the transfer process of the IV bags, and because the IV bags can be arranged so that they do not overlap each other, the problem of being damaged during the pickup process by the pickup device is eliminated. can be prevented.

In addition, in the present invention, the spacing of the IV bags is adjusted according to the spacing of the pickup device during the transfer process of the IV bags, thereby preventing malfunction in which the IV bags are not picked up by the pickup device.
