Description

The present invention relates to a system for sorting cases and loading carts in a distribution center, and more specifically, in a distribution center in which cases are sorted by delivery destination and loaded on carts with high efficiency and productivity. It relates to a case sorting and basket car stowage system.

First, a conventional example of case sorting and cage loading system in a distribution center will be described.

(Conventional example 1)
Conventionally, in a distribution center, as a method of sorting cases by delivery destination and loading them into carts, it is common to sort by conveyor and load carts based on the labels attached to the cases.

That is, as shown in FIG. 3, a large number of cases are transported by a transport conveyor 101 from an automated pallet warehouse, and in a delivery sorting area 102, a large number of loading conveyors are connected to the transport conveyor 101 in parallel and at intervals. A number of cases are sequentially transferred to 103A through 103J.

Then, each worker M who is standing by with a large number of basket cars 104 near each loading conveyor 103A to 103J sees the label of each case on each loading conveyor 103A to 103J and holds a specific case in his/her hand. It is to be loaded into the basket car 104 .

As for the conventional example 1, the invention of the "product case automatic stowage system" invented by the inventor of the patent document 1 can be mentioned.

The product case automatic stowage system picks up the corresponding product cases stored in the automated warehouse based on the shipping instruction information shown in FIG. Then, the characteristic information of the product case transported by the product transport step is recognized, and the recognized characteristic information is selected from among a plurality of storage transport means pre-allocated for each product case characteristic. A product case sorting step for sorting and transporting the product cases to a storage transport means corresponding to the above; A step of moving a cart truck to move the case to a stowage area, the shipping instruction information, the characteristic information of the product case recognized by the product case sorting step, and the placement of the product case on the transportation means for storage. stowage data is created from the state, and based on the stowage data, one of the plurality of car trucks moved to the stowage area by the car truck movement step is allocated to each shipping destination based on the shipping instruction information. a product case loading step of loading the product cases in a predetermined position and order on the car trucks, and a car truck unloading step of unloading each car truck on which the product cases are loaded by the product case stacking step from the stowage area. and a step, wherein the cart rack includes a rectangular product case mounting portion provided with a plurality of running wheels on the bottom side, and a frame erected vertically from one side edge of the product case mounting portion. Then, one end is attached to the frame and the other end is locked near the side edge of the product case placement portion on the side facing the frame, thereby stacking the product on the product case placement portion. and a product case fixing belt capable of fixing attached product cases.

In addition to Patent Document 1, Patent Documents 2 to 4 can be cited, and Patent Document 2 is shown in FIGS. A plurality of folded container chutes 50 assigned to each sorting destination, a folded container detection sensor 150 for detecting folded containers moving on the conveying line 30, folded container detection information from the folded container detecting sensor 150, and predetermined folded container chutes 50. Based on sorting instructions (package sorting information), at least one of a sorting line 40 and a plurality of folding container chutes 50 for guiding folded containers on the transport line 30 to folding container chutes assigned to respective folding container destinations. A grouping processing device 180 is provided for extracting specific folded containers from the conveying line 30 and accumulating them so that the folded containers are continuously discharged from one chute 50 for each destination.

In addition, in FIG. 1 of Patent Document 3, Patent Document 3 discloses a method of sorting goods that arrive in a mixed-loading manner in which different types of goods are mixed according to a plurality of destinations, in which first sorting equipment and second sorting equipment is used to perform a primary sorting process in which incoming goods taken out of mixed-type packing at the first sorting equipment are grouped into mixed boxes according to multiple sorting zones of the second sorting equipment, and the mixed boxes are stored at the first sorting equipment. 1 A process of conveying from the sorting equipment to each sorting zone of the second sorting equipment, and a final sorting process of putting the articles taken out of the mixing box into the final sorting opening for each destination in each sorting zone of the second sorting equipment. A method for sorting articles characterized by comprising

Furthermore, in Patent Document 4, in FIG. 1 of Patent Document 4, each received article is received and each article is sorted into each of a large number of frontages of a sorting zone to be sorted. Predetermine acceptance deadline rules that determine the acceptance deadline for the goods from the expiration date information of the goods, read the expiration date information attached to each item in the process of sorting the received goods, and use this expiration date information based on the acceptance deadline rule The acceptance period of the goods is calculated, the goods received within the acceptance period are sorted into a predetermined sorting destination corresponding to the delivery destination of the goods, and the goods received outside the acceptance period are returned. It is a method of sorting articles.

Therefore, in the inventions described in Documents 1 to 4 cited as Patent Documents of Conventional Example 1, as shown in the conventional example of FIG. , worker M is waiting.

Incidentally, Patent Documents 2 to 4 other than Patent Document 1 are conventional examples according to inventions other than those of the present inventors.

In addition, although the case label is checked and loaded into the relevant cart 104 , there are also problems in that loading errors occur at a certain rate and that the work of walking to the cart 104 with the case occurs.

Therefore, work and productivity are low, and mistakes occur, so a system that eliminates these problems is required.

(Conventional example 2)
The inventor of the present application developed the method shown in FIG. 4 and obtained a patent in 1998 ( Patent document 5).

In the method of the prior art 2, a large number of cases are conveyed by a transfer conveyor 201 from an automated pallet warehouse to a plurality of lanes 202A to 202E provided in a stacking station 200 so as to be divided into lanes 202A to 202E provided in the stacking station 200. Using a cage group 204 in which a plurality of cage trucks 203 arranged so as to correspond to 202E are assembled, each worker M loads a case into each cage truck 203 while watching the loading display instruction on the display.

In addition, in FIG. 4, 204A is an empty basket vehicle group.

However, in the case of Conventional Example 2, the speed at which cases are transported from the automatic pallet warehouse is not constant, and there is always unevenness.

After that, the cases are branched at the stowage station 200 and loaded onto the cage trucks 203. The types and numbers of cases for each cage truck 203 are also different, and lanes where more cases flow and lanes where less cases flow naturally occur.

If there are too many cases in one lane and the loading capacity is exceeded, the upstream conveyor will stop, and if there are too few cases, waiting will occur.

Moreover, various cases such as heavy ones, light ones, large ones, and small ones are flowed.

If a large and heavy case comes after a small and light case, the small case that has been loaded earlier will be temporarily placed on the ground in front of the basket car, and then loaded later. Wasteful work such as the one described above occurs not a little, and work productivity decreases.

JP 2015-37992 A Japanese Patent Application Laid-Open No. 2003-212314 JP-A-2004-67282 JP 2007-238332 A Patent No. 2966832

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the worker can load the case from the conveyor onto the cage car simply by changing the direction of his/her body. To provide a case sorting and cage truck loading system in a distribution center which can avoid such overwork.

A system for sorting cases and loading basket carts in a distribution center according to the present invention includes a distribution sorting area for sorting and stacking a large number of cases in a distribution center, and a large number of cases of different sizes from an automated pallet warehouse that constitutes the distribution center. a transport conveyor for transporting the case to the delivery sorting area, a right angle sorting conveyor installed in the delivery sorting area so as to be orthogonal to the transport conveyor, and arranged so as to occupy both sides of the transport conveyor in the delivery sorting area, A storage conveyor on which a large number of cases of different sizes sorted by a right-angle sorting conveyor are divided and transported toward workers waiting on the end side, and an arbitrary number of workers waiting on both ends of the storage conveyor are close to each other. and a group of basket cars arranged in a straight line parallel to the conveyer.

The features of the effects of the present invention will be further described below.

First of all, it is necessary to eliminate the work of walking carrying a case, which is overwork for workers.

The present invention is characterized in that the case can be loaded from the conveyor onto the cage car only by changing the direction of the body.

The loading time is only 2-3 seconds while holding the case. If the stacking work is continuously performed in 3 seconds, 1200 cases can be processed per hour.

In addition, by installing a right-angle branch conveyor for branching to the cage cart, it becomes possible to arrange the basket carts side by side without gaps, and as a result, the lateral movement distance of the worker can be shortened.

Next, as mentioned above, there is unevenness in the flow of cases, and it is necessary to eliminate cases that are concentrated in a certain lane, stopping the upstream conveyor, and waiting for cases to stop flowing.

Therefore, in the present invention, a sorting conveyor is installed in each delivery sorting area (loading area). The sorting conveyor sorts large and small cases for each basket car and can store them.

By installing a storage conveyor for each basket car, it is possible to absorb unevenness in the flow of cases from upstream.

In other words, the worker sees the accumulation of cases on the storage conveyor, moves laterally to the accumulated lane, easily, quickly, and without error, and loads the cases onto the basket car, and when finished, moves to the next accumulated lane. It becomes work to do.

This eliminates waiting and clogging, dramatically improving loading productivity.

Conventionally, depending on the size of the cases, there was a need to unload the loaded cases and load them again later. There are two storage conveyors, and workers select and load large or small cases to optimize loading. This eliminates wasteful transshipment work and improves productivity.

By installing two rows of conveyors in one cage truck, large and small cases can be efficiently stacked, but misloading does not occur because the cage truck and two rows of conveyors face each other.

It also eliminates the need for systems such as lamp guidance and display instructions. You can concentrate on the work of stacking without unnecessary operations, and anyone can easily work.

When the cart is full, the worker scans the barcode of the lane with a mobile device, prints a label from a mobile printer attached to the waist, attaches it to the cart, and transports it to the shipping platform.

According to the inventions of claims 1 to 7, the case can be loaded from the conveyor onto the basket car simply by changing the direction of the worker's body, which causes excessive work for the worker, such as walking while holding the case. It is possible to provide a case sorting and basket car loading system in a distribution center that can avoid this.

In addition, the right-angle sorting conveyor is composed of two types, a large-size case right-angle sorting conveyor and a small-size case right-angle sorting conveyor. Large and small cases can be efficiently loaded because the cases can be sorted and stored, and misloading can be avoided by having the large and small conveyors face each other for each basket car. A sorting and cart stowage system can be provided.

In addition, an arbitrary number of empty basket vehicles are arranged behind the basket vehicles arranged in a straight line in the delivery sorting area, so that when there is a shortage of basket vehicles, the replenishment time is short. Thus, it is possible to realize a case sorting and basket truck loading system in a distribution center capable of improving the workability of case sorting and basket truck loading work.

INDUSTRIAL APPLICABILITY The present invention is a case in a distribution center in which cases can be loaded from a conveyor onto a basket car simply by changing the direction of the worker's body, thereby avoiding excessive work such as walking with the case for the worker. For the purpose of providing a sorting and basket truck loading system, a delivery sorting area where a large number of cases are sorted and basket truck loading in the distribution center, and a large number of cases of different sizes from the automated pallet warehouse that constitutes the distribution center. a conveyer for conveying to a delivery sorting area; a right angle sorting conveyor installed in the delivery sorting area so as to be perpendicular to the transport conveyor; A storage conveyor in which a large number of cases of different sizes sorted by are divided and transported toward workers waiting on the terminal side, and an arbitrary number of workers waiting on both terminal sides of the storage conveyor. a group of basket cars arranged in a straight line parallel to the conveying conveyor, and the right-angle sorting conveyor is composed of two types of a large-size case right-angle sorting conveyor and a small-size case right-angle sorting conveyor; The storage conveyor was realized by making it possible to sort and store large and small cases by basket car in the delivery sorting area of each worker.

The system for sorting cases and loading carts in a distribution center according to an embodiment of the present invention will be described in more detail below with reference to the drawings.

As shown in FIGS. 1 and 2, a system 1 for sorting cases and loading carts in a distribution center according to this embodiment includes a delivery sorting area 3 for sorting and loading a large number of cases 2 in a distribution center. , a transport conveyor 10 for transporting a large number of cases 2 of different sizes from an automated pallet warehouse that constitutes a distribution center to a delivery sorting area 3; , which are arranged in the delivery sorting area 3 so as to occupy both sides of the transport conveyor 10, and a large number of cases 2 of different sizes sorted by the right angle sorting conveyor 11 are divided and directed to the worker M who waits on the terminal side. The storage conveyor 13 conveyed by the storage conveyor 13 and an arbitrary number of workers M waiting on both end sides of the storage conveyor 13 are arranged in a straight line parallel to the transfer conveyor 10 and on both sides of the storage conveyor 13. It has cage car groups 20, 20 arranged in line.

The cage car group 20 is composed of a large number of individual cage cars 21 . For example, the cage vehicle group 20 in one row is constructed by connecting 25 cage trucks 21, and the cage truck group 20 in the other row is similarly constructed by connecting 25 cage trucks 21.例文帳に追加

As shown in FIG. 2, the right-angle sorting conveyor 11 has a parallel configuration of two types, a large-size case right-angle sorting conveyor 11A and a small-size case right-angle sorting conveyor 11B. 11, in the delivery sorting area 3 of each worker M, the cases 2 different in size and size are sorted in units of basket carts 21, and transported to the workers and stored in two rows.

An arbitrary number (e.g., eight) of empty basket vehicles 30 are arranged behind the basket vehicles 20 arranged in a straight line in the delivery sorting area 3.

In the present embodiment, an example is shown in which each empty cage car group 30 is composed of, for example, 30 cage cars 31 .

Such provision of the empty basket truck group 30 shortens the replenishment time when the basket trucks are in short supply, and has the effect of improving the workability of case sorting and basket truck loading work.

Now, the configuration of the present invention described above includes the following configuration.

First, for the cases 2 from the automated pallet warehouse, before the cases 2 are carried from the transfer conveyor 10 to the right-angle sorting conveyor 11, the barcode (not shown) of each case 2 is read, and the size (weight) of each case 2 is read. (including weight and weight) and storage information corresponding to each sorting destination, and a sorting reading means 14 capable of inputting the recognition information as sorting control information for the right-angle sorting conveyor 11 is provided. (See Figure 1)

Therefore, according to the information read by the sorting reading means 14 provided in FIG. It is configured so that it can be transported to

As shown in FIG. 1, the right-angle sorting conveyors 11 are composed of two kinds of large size right-angle sorting conveyors 11A and small-size right angle sorting conveyors 11B in parallel as described above. A motorized roller conveyor (not shown) equipped with a right-angle branching device is employed for the right-angle branching to the installed storage conveyor 13 .

That is, a motor roller conveyor equipped with a right angle branching device is used for the right angle branching for each storage conveyor 13, and the right angle branching device equipped on the motor roller is POWER MOLLER (registered trademark) manufactured by Ito Denki Co., Ltd. A &idPAC (registered trademark) or the like is adopted, and the carrying-in case 2 can be branched at right angles to the storage conveyors 13 on both the left and right sides with respect to the direct transport direction, and can be sorted for storage.

When the cases 2 are conveyed into the right angle sorting conveyor 11 by the large size right angle sorting conveyor 11A and the small size right angle sorting conveyor 11B which are composed of the motor roller conveyors equipped with the right angle branching device, each case 2 is input. Based on the recognition signal received, the storage conveyor 13 is divided at right angles through the right angle branching device and sorted.

In addition, the right angle sorting conveyor 11 divides the cases 2 carried in from the transfer conveyor 10 into a large number of cases in a narrow space (horizontal space) that branches at right angles to the storage conveyors 13 arranged in rows on one side 25 and both sides 50 of the above 1 to 50. It can be configured to have a sorting frontage (a space in the row direction of the storage conveyor 13).

The storage conveyor 13 sorts and stores large and small cases 2 among the cases 2 with respect to one basket car 21 in the arrangement direction of the basket car group 20 with respect to the arranging direction. It is configured such that two storage conveyors 13 for storage are arranged in pairs.

In the configuration of FIG. 1, each of the storage conveyors 13 on one side 25 and both sides 50 has a pair of storage conveyors 13a for the small cases 2 and an adjacent storage conveyor 13b for the large cases 2, which are arranged on the terminal side. The storage conveyors 13a and 13b are alternately arranged facing each basket wheel 21 in the same manner.

Each of the storage conveyors 13 is composed of an inclined free roller conveyor (not shown), and the large cases 2 that are orthogonally sorted and branched at right angles by the large size right angle sorting conveyor 11A of the right angle sorting conveyor 11 are transferred to the storage conveyor 13b, and The small cases 2 sorted at right angles by the small-size right-angle sorting conveyor 11B and branched at right angles are stored in the storage conveyor 13a and can be stored in the opposing single basket car 21. - 特許庁

An example of a specific embodiment according to the configuration of the system 1 for sorting and loading carts in a distribution center according to the above description will be described.

First, the sorting of the case 2 and the flow of the stowage system 1 for the cage car 21 of the embodiment are sorted from the automatic pallet warehouse 5 in the system 1 to the storage conveyors 13 from 1 to 50 on both sides of the orthogonal sorting conveyor 11. 50 possible store shipment items are picked together (batch picking).

At this time, regarding the shipping order of the cases 2 from the automatic pallet warehouse 5, the barcode of each case 2 (including the characteristic information of each case 2 registered in the product master and the specified information such as the 50 stores) While reading through a bar code reader (not shown), the computer (control unit, not shown) controls shipment so that heavy cases and large-sized cases 2 are shipped first.

Such control can also be carried out through the sorting and reading means 14 described above.

In addition, such control is such that when the worker at the terminal of each of the storage conveyors 13 from 1 to 50 loads the cases 2 onto the respective cage carts 21 corresponding to them, the light small cases 2 come first, and then the heavy cases 2 come first. This is because when the large case 2 arrives, it is necessary to unload and reload the loaded product cases.

Therefore, the system 1 of the present invention is a system developed and invented also for avoiding and eliminating wasteful loading of the cage 21 by the worker.

As is clear from the above configuration, the system 1 of the present invention has one cage truck 21 for each cage truck 21 so that the work for loading the cage trucks 21 and the work for loading the cases 2 into the cage trucks 21 can be carried out more speedily and easily. It consists of a structure in which two rows of storage conveyors 13a and 13b for large and small sizes are alternately arranged in pairs.

In such a configuration, the operation of stacking the cases 2 on one cage truck 21 involves first stacking the heavy cases 2 and the large cases 2, and then stacking the cases 2 to a certain height relative to the cage truck 21. By stacking the light cases 2 and the small cases 2, damage to the cases 2 loaded in the basket truck 21 and stability of stacking in the basket truck 21 can be secured and the stability can be improved.

For this reason, as a method of sorting one basket car 21 into the storage conveyors 13a and 13b for large and small cases, the characteristic information of each product case 2 registered in the product master as described in the above configuration is Through the sorting and reading means 14, it is possible to automatically sort while reading in the carry-in process before right angle branching by weight and case size.

At this time, each case 2 carried into the right-angle sorting conveyor 11 having the above-described configuration is transferred to the storage conveyors 13a and 13b for each of 1 to 50 stores via the large-size right-angle sorting conveyor 11A and the small-size right-angle sorting conveyor 11B. It can be automatically sorted by right angle branching.

Therefore, the situation of the storage carried in and transferred to each of the storage conveyors 13a and 13b paired by the paired large and small size right angle sorting conveyors 11A and 11B of each of the storage conveyors 13 from 1 to 50 is determined by the work. A person visually observes this, and while moving laterally to the lane where the cases 2 are accumulated, the storage and the cage car 21 are arranged facing one to one (see FIG. 1). The loading operation for the cage truck 21 of the predetermined case 2 can be performed by the operation of loading the cage truck 21 without scanning this.

Therefore, in the system 1, when the case 2 is full in the basket car 21, the lane bar code (not shown) installed at the terminal of each of the storage conveyors 13 of the above configuration, for example, 1 to 50 While scanning this with a mobile terminal carried in advance by the worker, by inputting the full setting in advance, a barcode label for sorting the full cage 21 is output via the mobile printer carried by the worker. By configuring the label so that it can be printed out, the label is attached to the filled car 21.例文帳に追加

As a result, the sorting and loading of the basket trucks 21 for each of the 1 to 50 stores can be completed.
The full basket truck 21 is replaced with the empty basket truck 31 of the empty basket truck group 30 to continue the stowage operation.

The full basket trucks 21 are loaded in the space between the basket truck group 20 and the empty basket truck group 30 in the delivery sorting area 3 of FIG. It will be transported to a separate space.

In the above description, in the system 1 of the present invention, each storage conveyor 13 and the cage car 21 are substantially linked, and it is necessary to scan the label of the case 2 each time as in the conventional art. Cases can be easily loaded at a high speed without causing any mistakes in loading.

As is clear from the description of the above embodiment, in the system 1 for sorting cases and loading basket cars in a distribution center according to this embodiment, the worker M moves to a lane where there are many cases 2 on the storage conveyor 13, and picks up the baskets. Large and small cases are selected and loaded so that the cases can be properly loaded on the car 21.例文帳に追加

As a result, the redundant work of temporarily placing the case 2 in front of the cage car is eliminated, and the distance from when the case 2 is picked up to the cage car 21 is minimized.

That is, the continuous loading of Case 2 is possible, and the waiting time is almost eliminated, and the loading speed is increased. In addition, the storage conveyor 13 and the cage car 21 are one-to-one, and loading errors are eliminated.

A single worker can handle, for example, about 12 baskets while moving laterally, and the loading productivity can reach 500 cases per hour. In other words, it is possible to ensure productivity that is more than double that of the conventional method.

As described above, according to this embodiment, it is possible to greatly contribute to the improvement of the productivity of case sorting and loading work.

With the conventional method, the average number of cases that can be processed per hour is about 250. However, according to this embodiment, it is possible to process about 500 cases per hour, which doubles the productivity.

Another problem at distribution centers is securing workers. In particular, it is difficult to recruit people for simple tasks that require labor. According to this embodiment, the same processing can be performed by half the number of people as in the conventional case, and there is no need to walk while carrying a heavy case, and fatigue is reduced.

Furthermore, the stacking work passage is raised to the height of the casters of the cage truck 21, that is, to the floor surface of the cage truck 21, thereby facilitating the operation of lifting the cases. In terms of work, the work of lifting the case is more difficult than the work of lowering the case. Although the height is raised up to the height of the floor surface of the cage 21, the effect of reducing work is large.

INDUSTRIAL APPLICABILITY The present invention can be widely used in distribution centers and the like that handle commodities and articles in the food field, machine processing field, and other industrial fields.
