Description

Sorting system for goods transportation

The present invention relates to a sorting system for transporting goods, and more specifically, to a sorting system for transporting goods that can place goods in the correct position on a cart of a sorter body by eliminating the phenomenon of goods being misaligned or blown away due to air resistance even when the goods are accelerated in the acceleration section of auto induction.

The term logistics is an abbreviation for physical distribution, and is a general term for the functions or activities that effectively move goods and products from producers to consumers. It generally refers to various activities such as packaging, unloading, transportation, storage, and information.

Normally, the transportation of goods and materials involves several processes such as packaging, storage, collection/loading, transportation, unloading/delivery, and storage. Regardless of the means of transportation used, the movement of goods and materials is impossible without going through these processes. The comprehensive view of all of these movements is physical distribution (logistics).

In recent years, mass production, mass sales, and mass consumption have become the trends of the times, and the importance of logistics is gradually increasing as the need to improve the flow of materials between them has grown.

In modern enterprises, not only the commercial distribution activities, that is, the transaction part, but also the logistics activities that accurately and quickly deliver goods to the hands of consumers have emerged as important parts. In other words, with economic development, the view emerged that it would be impossible to win in fierce corporate competition if only the reduction of production costs was pursued, and that distribution costs should also be reduced as much as possible.

Currently, as a means of logistics rationalization, the construction of distribution centers, which concentrate delivery centers, truck terminals, and warehouse complexes around large cities, the promotion of unit load systems, which seek to streamline transportation using containers or pallets, and cooperative integrated transportation, which aims to improve transportation efficiency through organic combination of each transportation agency, are being carried out, and some are being fostered by the government.

Although the term logistics is a very broad term, when applying its meaning to the environment of a distributor distributing specific goods or items (hereinafter collectively referred to as cargo), the series of actions of classifying, or sorting, cargo and transporting it can also be viewed as logistics.

A series of systems for sorting cargo in a logistics center (facility) are called a logistics transport sorting system. A logistics transport sorting system is also simply called a logistics sorter.

This sorting system for material transport is composed of various facilities, i.e., devices. For example, the sorting system for material transport includes an auto induction, which is a series of facilities that stably position cargo in designated locations on the sorter body, i.e., multiple carts.

At this time, in order to stably place or settle the cargo on the cart, which is the designated location of the sorter body implemented as a closed loop, an acceleration section in which acceleration is formed in the auto induction must be applied. In this case, there is a problem in which the cargo position is distorted or blown away due to air resistance resulting from the acceleration.

In particular, recently, there are many cases where cargo is packed in a plastic bag called a polybag. Since the weight of such cargo is small compared to its volume, the phenomenon of the cargo being out of position or flying due to air resistance when acceleration occurs in auto induction is bound to become even more severe. Therefore, it is difficult for the cargo to be properly positioned on the cart of the sorter body.

Accordingly, in order to prevent such problems, most distributors are applying methods of manual sorting or sorting by placing them on dedicated trays. Considering that this inevitably leads to problems such as reduced water flow, increased layout area, increased investment and production costs, and the need for additional installation of tray recovery systems, technological development is necessary to solve these problems.

In order to fully understand the present invention, its operational advantages, and the objects achieved by practicing the present invention, reference should be made to the accompanying drawings illustrating preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, the present invention will be described in detail by describing a preferred embodiment of the present invention with reference to the attached drawings. The same reference numerals presented in each drawing represent the same components.

FIG. 1 is a plan view of a sorting system for material transport according to one embodiment of the present invention, FIG. 2 is an enlarged view of a main part of FIG. 1, FIG. 3 is a detailed view of FIG. 1, FIG. 4 is a side view of FIG. 3 excluding the sorter body, FIG. 5 is a drawing emphasizing a cargo supporting device in FIG. 4, FIG. 6 is a structural diagram of an air injection unit, and FIG. 7 is a control block diagram for the sorting system for material transport of FIG. 1.

Referring to these drawings, the sorting system for transporting logistics according to the present embodiment is applied to a logistics center (facility) that transports and classifies cargo, and eliminates the phenomenon of cargo being misaligned or blown away due to air resistance even when the cargo is accelerated in the acceleration section of auto induction (120), thereby allowing the cargo to be properly placed on a cart (111, Cart) of the sorter body (110). Here, the cargo may be cargo packed in a polybag, which is a plastic bag.

As briefly mentioned above, in order to stably place or settle a cargo on the cart (111), which is the designated location of the sorter body (110) implemented as a closed loop, an acceleration section in which acceleration is formed in the auto induction (120) must be applied. In this case, there is a problem in that the cargo position is distorted or blown away due to air resistance resulting from the acceleration.

In particular, recently, there are many cases where cargo is packed in a plastic bag called a polybag. Since such cargo has a small weight relative to its volume, the phenomenon of the cargo being misaligned or blown away due to air resistance when acceleration occurs in the acceleration section of the auto induction (120) is bound to become even more severe. Therefore, it is difficult for the cargo to be properly positioned on the cart (11) of the sorter body (110).

Accordingly, a method of sorting manually or sorting by placing on a dedicated tray has been generally applied, but in such a case, problems such as a decrease in the amount of material handled, an increase in the layout area, an increase in investment and cost, and an additional installation of a tray recovery system inevitably arise. To solve these problems, a sorting system for material transport according to this embodiment can be applied.

The sorting system for logistics transport according to the present embodiment may include a sorter body (110), an auto induction (120) positioned adjacent to the sorter body (110), and a cargo supporting device (140) provided on the auto induction (120).

The sorter body (110) is equipped with a plurality of carts (111) that allow cargo to be placed while being sorted to a designated location. Cargo can be placed and placed on a corresponding cart (111) according to the type of cargo.

The auto induction (120) is placed adjacent to the sorter body (110) and is a means for loading cargo so that the cargo can be placed on the cart (111) of the sorter body (110). Therefore, the auto induction (120) takes on a conveyor structure.

This auto induction (120) may include a receive conveyor (121) that receives cargo, a synchronization conveyor (122) that is connected to the receive conveyor (121) to transport cargo but is inline with the receive conveyor (121) and forms an acceleration section of cargo that is faster than the receive conveyor (121), and a junction conveyor (123) that is connected to the synchronization conveyor (122) to transport cargo but has an end region disposed on the sorter body (110) so that the cargo joins the cart (111) of the sorter body (110).

The receiving conveyor (121), the synchronous conveyor (122), and the junction conveyor (123) all adopt a belt conveyor structure. However, in the case of the junction conveyor (123), a structure of multiple unit belt conveyors (123a, 123b, 123c...) with different lengths is adopted. This is because the junction conveyor (123) and the sorter body (110) must be arranged at an angle to each other. The angle between them is about 30 degrees, but this angle can be changed as desired.

A cargo size check unit (130) that checks the size of cargo can be placed between the receiving conveyor (121) and the synchronous conveyor (122).

The receiving conveyor (121), the synchronous conveyor (122), and the junction conveyor (123) forming an inline structure transport cargo and deliver it to the cart (111) of the sorter body (110).

At this time, as mentioned above, in order to stably place or settle the cargo on the cart (111), which is the designated location of the sorter body (110) implemented as a closed loop, an acceleration section in which acceleration is formed in the auto induction (120) must be applied. The acceleration section corresponds to the synchronous conveyor (122) and the junction conveyor (123).

At this time, the synchronous conveyor (122) is accelerated more than the receiving conveyor (121). And, the speed of the junction conveyor (123) may be the same as that of the synchronous conveyor (122) or may be faster than that of the synchronous conveyor (122). Typically, the speed of the junction conveyor (123) may be faster than that of the synchronous conveyor (122). Accordingly, the cargo may be accelerated while passing through the receiving conveyor (121), the synchronous conveyor (122) and the junction conveyor (123), and then transferred to the cart (111) of the sorter body (110).

In this way, when the receiving conveyor (121), the synchronous conveyor (122), and the junction conveyor (123) are all operated at an accelerated speed rather than a constant speed, the cargo placed and transported thereon, especially in the case of vinyl cargo that is easy to blow away as in this embodiment, may be misaligned or blown away due to air resistance resulting from the acceleration. In this case, it is difficult for the cargo to be properly positioned on the cart (11) of the sorter body (110). Therefore, the cargo supporting device (140) is applied.

A cargo supporting device (140) is provided in the auto induction (120) and supports the cargo so that the cargo does not become misaligned or blow away due to air resistance when transporting the cargo through the auto induction (120).

In this embodiment, the cargo supporting device (140) is applied as an air-injection type cargo supporting device (140) that induces the cargo to not be misaligned or blown away by the pressure of air. In other words, the cargo supporting device (140) in this embodiment has a structure that injects air.

In applying the air-jet type cargo supporting device (140), in this embodiment, the air-jet type cargo supporting device (140) is placed on a synchronous conveyor (122).

Of course, the air-jet type cargo supporting device (140) may be placed on the junction conveyor (123) in addition to the synchronous conveyor (122). However, since the position of the cargo may be distorted during the conveyance process when air is sprayed on the junction conveyor (123), the air-jet type cargo supporting device (140) is placed on the synchronous conveyor (122) in this embodiment.

An air-injection type cargo supporting device (140) may include a device frame (150) that is arranged on a synchronous conveyor (122) and forms a plurality of acceleration sections (151 to 153) along the cargo transport direction of the synchronous conveyor (122), and an air-injection unit (160) that is arranged on at least one side of the acceleration sections (151 to 153) of the device frame (150) and injects air to cargo passing through the corresponding acceleration sections (151 to 153).

Here, the plurality of acceleration sections (151 to 153) may include a first acceleration section (151) adjacent to the receiving conveyor (121), a second acceleration section (152) connected to the first acceleration section (151), and a third acceleration section (153) arranged on both sides with the second acceleration section (152) and the junction conveyor (123), and the air injection unit (160) may be arranged in the first and second acceleration sections (151, 152). Of course, the air injection unit (160) may also be arranged and operated in the third acceleration section (153), but the test results have proven that it is effective to arrange the air injection unit (160) in the first and second acceleration sections (151, 152) except for the third acceleration section (153).

Meanwhile, the air injection unit (160) applied to this embodiment is a fan motor type air injection unit (160) provided as a fan motor type, and is arranged in multiple units in the first and second acceleration sections (151, 152).

This fan motor-type air injection unit (160) may include a unit casing (161) coupled to one side of the device frame (150), an air blower (162) provided within the unit casing (161) that generates air and injects it onto cargo, and a blower supporter (163) that supports the air blower (162).

The unit casing (161) is provided with a rotation support member (164) that supports the air blower (162) and the blower supporter (163) so as to be rotatable as one body. Due to the rotation support member (164), the air blower (162) and the blower supporter (163) can be rotated as one body as shown in Fig. 6, and the direction of air injection toward the cargo can be adjusted by this action.

Meanwhile, the sorting system for logistics transport according to the present embodiment is further equipped with a speed detector (180) and a system controller (190) as means for controlling the system.

The speed detector (180) detects the speed of the synchronous conveyor (122). Then, the system controller (190) automatically controls the operation of the air injection unit (160) based on the detection information of the speed detector (180). In other words, the system controller (190) operates the air injection unit (160) only when there is acceleration, thereby causing air to be injected onto the cargo.

A system controller (190) that performs this role may include a central processing unit (181, CPU), a memory (182, MEMORY), and a support circuit (183, SUPPORT CIRCUIT).

The central processing unit (181) may be one of various computer processors that can be applied industrially to automatically control the operation of the air injection unit (160) based on detection information from the speed detector (180) in this embodiment.

The memory (182, MEMORY) is connected to the central processing unit (181). The memory (182) is a computer-readable recording medium that may be installed locally or remotely, and may be at least one readily available memory such as a random access memory (RAM), a ROM, a floppy disk, a hard disk, or any digital storage form.

The support circuit (183, SUPPORT CIRCUIT) is coupled with the central processing unit (181) to support typical operations of the processor. The support circuit (183) may include a cache, a power supply, a clock circuit, an input/output circuit, a subsystem, etc.

In this embodiment, the system controller (190) automatically controls the operation of the air injection unit (160) based on the detection information of the speed detector (180). A series of control processes, etc. may be stored in the memory (182). Typically, a software routine may be stored in the memory (182). The software routine may also be stored or executed by another central processing unit (not shown).

Although the processes according to the present invention have been described as being executed by software routines, it is also possible for at least some of the processes of the present invention to be executed by hardware. As such, the processes of the present invention may be implemented as software executed on a computer system, implemented as hardware such as an integrated circuit, or implemented by a combination of software and hardware.

Below, the operation of the sorting system for logistics transport according to the present embodiment is described.

As in Fig. 3, cargo, i.e., vinyl cargo, placed on the receiving conveyor (121) of the auto induction (120) is transported through the receiving conveyor (121), the synchronous conveyor (122), and the junction conveyor (123), and then delivered to the corresponding cart (111) of the sorter body (110). Since the air injection unit (160) of the cargo supporting device (140) injects air onto the cargo in the synchronous conveyor (122), even if the cargo is accelerated in the synchronous conveyor (122), the cargo does not shift in position or fly away, and as a result, the cargo can be properly positioned on the cart (111) of the sorter body (110).

According to this embodiment, which operates with the structure described above, even if the cargo is accelerated in the acceleration section of the auto induction (120), the phenomenon of the cargo being misaligned or blown away due to air resistance is eliminated, thereby enabling the cargo to be properly positioned on the cart (111) of the sorter body (110).

FIG. 8 is a plan view of a sorting system for material transport according to another embodiment of the present invention, FIG. 9 is a side view of FIG. 8 excluding the sorter body, and FIG. 10 is a control block diagram for the sorting system for material transport of FIG. 8.

Referring to these drawings, the sorting system for logistics transport according to the present embodiment may include a sorter body (110), an auto induction (120) positioned adjacent to the sorter body (110), and a cargo supporting device (240) provided on the auto induction (120). The structure, function, and role of these are the same as those of the above-described embodiment. Therefore, a duplicate description will be avoided.

Meanwhile, in the present embodiment, the cargo supporting device (240) includes an air injection unit (260), and the air injection unit (260) at this time is applied as an air nozzle-type air injection unit (260) provided as an air nozzle type.

This air nozzle-type air injection unit (260) may include an air supply duct (261) through which air is supplied, and an air nozzle (262) provided in multiple locations in the air supply duct (261) and delivering air within the air supply duct (261) to cargo.

A plurality of air nozzles (262) are provided at different locations in the air supply duct (261), which is a large structure, and the air nozzles (262) can only operate the corresponding air nozzles (262) according to the size of the cargo. Accordingly, an individual electronic valve (not shown) may be attached to the air nozzle (262), and the operation of this electronic valve may be controlled by the controller (290).

In other words, the controller (290) can control to operate only the corresponding air nozzle (262) among the plurality of air nozzles (262) based on the cargo size information from the cargo size check unit (130).

Even if this embodiment is applied, the phenomenon of the cargo being misaligned or blown away due to air resistance even when the cargo is accelerated in the acceleration section of the auto induction (120) can be eliminated, thereby allowing the cargo to be properly positioned on the cart (111) of the sorter body (110).

FIG. 11 is a side view of a sorting system for logistics transport according to another embodiment of the present invention, and FIG. 12 is a control block diagram for the sorting system for logistics transport of FIG. 11.

Referring to these drawings, the sorting system for logistics transport according to the present embodiment may include a sorter body (110), an auto induction (120) arranged adjacent to the sorter body (110), a cargo supporting device (340) provided in the auto induction (120), and a system controller (390). The structure, function, and role of these are the same as in the above-described embodiment. Therefore, a duplicate description is avoided.

A cargo supporting device (140) may include a device frame (150) that is arranged on a synchronous conveyor (122) and forms a plurality of acceleration sections (151 to 153) along the cargo transport direction of the synchronous conveyor (122), and an air injection unit (160) that is arranged on at least one side of the acceleration sections (151 to 153) of the device frame (150) and injects air to cargo passing through the corresponding acceleration sections (151 to 153). In the present embodiment, the air injection unit (160) may also be arranged on the first and second acceleration sections (151, 152).

The air injection unit (160) applied to this embodiment may also be a fan motor type air injection unit (160) provided as a fan motor type, and a unit mover (360) is connected to this air injection unit (160). The unit mover (360) is a means for moving the position of the fan motor type air injection unit (160) and is controlled by a system controller (390).

In the present embodiment, if a unit mover (360) that moves the position of a fan motor-type air injection unit (160) is further applied and these are controlled by a system controller (390), there is an advantage in that air injection to vinyl cargo can be accurately set.

Even if this embodiment is applied, the phenomenon of the cargo being misaligned or blown away due to air resistance even when the cargo is accelerated in the acceleration section of the auto induction (120) can be eliminated, thereby allowing the cargo to be properly positioned on the cart (111) of the sorter body (110).

As such, the present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should be considered to fall within the scope of the claims of the present invention.
