Description

  The present invention relates to a merchandise sorting system, and more particularly to a merchandise sorting system that sorts merchandise by putting the merchandise into each shipping pallet prepared for each of a plurality of shipping destination stores.

  As a conventional example of sorting various types of products that are sequentially supplied by product type by shipping destination each time they are supplied, an operator manually places them on a pallet for each shipping destination placed at a fixed location. A so-called seeding method in which products are put in order is known (see, for example, Patent Document 1 (FIG. 8)).

  In this seeding method, as shown in FIG. 10, the sorting worker 101 takes out two to three kinds of desired products from the product shelf 103, puts them on the cart 105, and pallets 109 of the fixed shelf 107 classified by shipping destination. The product is put in like a seed. It is shipped when all the products are ready on the shipping destination pallet 109.

  On the other hand, as another conventional example, as shown in FIG. 11, a sorting operation using a rotary tray device 110 that conveys a tray 113 is also known. This conventional example includes two rotary tray devices 110, a worker 111 is disposed between the two rotary tray devices 110, and the worker 111 is behind the worker 111. In this method, a product is taken out from 112, and the product is alternately placed into two trays 110 that are placed on and transported to the two rotary tray devices 110 (for example, Patent Documents). 1 (FIG. 1).)

  However, according to the conventional example using the seeding method of FIG. 10, the flow line of the worker 101 is long and the work efficiency is poor. In addition, when many types of products are required per pallet 109, several operations must be repeated to put all the products into the pallet 109, and the work time becomes longer and the product is shipped. There was a problem that the work could not be done at once and was inefficient.

  Furthermore, with the recent increase in convenience store openings, the number of destination stores has increased and the number of orders per store has decreased. With the conventional sowing method, the number of fixed locations for placing pallets has increased, and one fixed location has been established. The problem that the number of stacking steps per unit has been reduced and the space efficiency of the sorting area has been reduced has become apparent.

  On the other hand, according to the conventional example of the rotating tray method of FIG. 11, when there are few retail stores that order the product and there are few trays that require product input, the desired tray is transported to the operator input position. There is a waiting time until the product is loaded, and the trays are transported in units of stacks, so the product input height varies depending on the order quantity, resulting in poor work efficiency. There is a problem that there is a limit to speeding up the operation speed.

  The present invention has been made to solve such a problem, shortening the work flow of the worker, reducing the waiting time for the product input work, and improving work efficiency and saving space. The purpose is to obtain a product sorting system for planning.

The merchandise sorting system according to the present invention is a merchandise sorting system for sorting merchandise by putting the merchandise into each shipping pallet prepared for each of a plurality of shipping destination stores, and placing the shipping pallet on a predetermined basis A loop conveyor that conveys in a loop on the track, and a pallet that sorts the shipping pallet placed on the loop conveyor into an in-process pallet that is continuously loaded with products and a full pallet that is full of products A sorting means; a transfer means for sending out the shipping pallet sorted out as an in-process pallet by the pallet sorting means; and a predetermined product input for the shipping pallet sent from the loop conveyor by the transferring means A product loading conveyor that transports the product to a position and returns it to the loop conveyor after the product is loaded; Placed side by side one or more for each of the shipping destination store on top of the conveyor, the said shipping pallet sorted and packed pallet by sorting means, removed from the loop conveyor, stacking device for stacking sequentially stage by the shipping destination store Is a product sorting system.

  According to this invention, it is configured as described above, and it is transported to a predetermined product input position by the loop conveyor and the product input conveyor, and the full shipping pallets are stacked, and only the in-process pallet is transferred by the loop conveyor. As a result, it is possible to shorten the work flow of the operator, reduce the waiting time for the product input work, increase work efficiency, and save space.

Embodiment 1 FIG.
FIG. 1 is a perspective view showing the configuration of a product sorting system according to Embodiment 1 of the present invention. FIG. 2A is a top view showing the commodity sorting system, and FIG. 2B is a side view. The product sorting system of the present invention responds to orders for small quantities of various products from retail stores such as supermarkets and convenience stores for products that are sequentially supplied in large quantities by product type at shipping sites, distribution centers, distribution centers, etc. It is particularly suitable for sorting.

  As shown in FIG. 1 and FIG. 2, the product sorting system in the present embodiment has one or more units that place a shipping pallet for loading sorted products and convey it in a loop on a predetermined track. The loop conveyors 1A to 1D (four in FIG. 1) and the shipping pallet sent from the loop conveyors 1A to 1D are transported to a predetermined product input position, and after the products are input, the loop conveyors 1A to 1D are again transferred to the loop conveyors 1A to 1D. One full product loading conveyor 2 to be returned and the full shipping pallet 12 which is full of products provided on the top of the loop conveyors 1A to 1D are taken out from the loop conveyors 1A to 1D and sequentially stacked for each destination store. A stacking device 11 is provided.

  Further, in the present embodiment, an empty pallet supply device 3 for automatically supplying a new shipping pallet (empty pallet) to the product input conveyor 2, and a label attaching device for attaching a barcode label for identifying the pallet to the supplied empty pallet 4. A work instruction device 8 that provides input instruction information for the worker 7 regarding the shipping pallet that has been conveyed to a predetermined product input position 6 of the product input conveyor 2, and a computer 14 that controls the entire apparatus. Furthermore, it is provided.

  The barcode label for pallet identification attached by the label attaching device 4 is printed with a barcode including ID information for identifying the pallet, and shipping destination store information (such as shipping destination store name). Product information (product name, product classification, manufacturer name, etc.) and stacking information (such as the address number of the stacking device to be stacked) are printed together. Accordingly, each worker can easily determine whether the pallet is correct or not, and thus can prevent erroneous delivery after shipment.

  As shown in FIG. 1 and FIG. 2, each loop conveyor 1 </ b> A to 1 </ b> D is configured by installing two forward and reverse roller conveyors in parallel. Thereby, the pallet conveyed to the downstream end 13 of the forward row is transferred to the upstream end position 15 of the backward row by the lateral feed mechanism. Similarly, the pallet that has reached the downstream end 9 in the reverse row is transferred to the upstream end position 10 in the forward row by the lateral feed mechanism. By doing so, loop-shaped conveyance is performed. Further, a branch mechanism (transfer means) is provided at the downstream end 9 of the return of each loop conveyor 1A to 1D, so that it escapes from the loop-shaped conveyance, and the product loading conveyor from each loop conveyor 1A to 1D. 2 The lower pallet can be carried out and transferred. Similarly, the upstream upstream end 10 also has a branching mechanism (returning means), and carries the pallet from the lower stage of the product input conveyor 2 to the loop conveyors 1A to 1D. In addition, what is necessary is just to comprise a transfer means and a return means from the short belt conveyor or the arm etc. which rotate, for example.

  As shown in FIG. 1 and FIG. 2 (b), the product input conveyor 2 is configured by installing two forward and reverse belt conveyors in two upper and lower stages. The lower conveyor is connected to each of the loop conveyors 1A to 1D. The pallet that has reached the downstream end of the lower conveyor is transferred to the upstream end of the upper conveyor by the lifter mechanism. In the upper conveyor, after merging with the pallet supplied from the empty pallet supply device 3, the pallet is transported to the product input position 6 and the pallet is temporarily stopped, and the product is input by the operator 7. The pallet that has completed the introduction of the product is transferred to the lower conveyor when it is conveyed to the downstream end of the upper conveyor, and is transferred to each of the loop conveyors 1A to 1D after being conveyed by the lower conveyor.

  As for the stacking device 11, the number according to the number of stores of the shipping destination is arranged in the upper part of each loop conveyor 1A-1D (that is, the stacking device 11 is provided on a one-to-one basis with respect to the shipping destination. ing.). Each stacker 11 is assigned an address number for each store of the shipping destination. The pallet transported on the loop conveyors 1A to 1D reaches the position of the stacking device 11 having an address number that matches the address number indicating the ship-to store, which can be read from the pallet identification bar code label affixed to the pallet. At that time, the sheet is stopped and stacked on the stacking device 11 as indicated by an arrow X in FIG. 1 by a lifter mechanism installed at the lower part of the conveyors of the loop conveyors 1A to 1D. The state where pallets are stacked on each stacking device 11 is shown in FIGS. 1 and 2B.

  At the time when the sorting of the products is completed, the pallet for each shipping destination store stacked in the stacking device 11 is transferred onto the loop conveyors 1A to 1D in units of stacking as indicated by the arrow Y in FIG. It will be posted. The transferred stack unit is transported to the shipping place by transporting the loop conveyors 1A to 1D in the forward direction. At this time, the reverse conveyor is reversed, and the stacked units are shipped by conveying the stacked units 12 in the same direction as the forward conveyor.

  FIG. 3 is a block diagram showing the internal configuration of the commodity sorting system in the present embodiment. The configurations shown in FIGS. 1 and 2 are denoted by the same reference numerals. As shown in FIG. 3, the merchandise sorting system in the present embodiment is connected to an existing host 20, and includes a work instruction device 8, a computer 14, a foot switch 16 provided at the feet of the worker 7, a label sticking device 4, Product loading conveyor 2, loop conveyors 1 </ b> A to 1 </ b> D, stacking device 11, weight checker 17 for monitoring the weight of the pallet, and information on a pallet identification barcode label attached to the pallet. A pallet bar code reader 18 for reading the pallet, a sensor 19 for detecting the conveyed pallet, and an empty pallet supply device 3.

  The weight checker 17 is provided on the product loading conveyor 2 and measures the difference weight between the pallet weight of the shipping pallet before the product is loaded and the pallet weight after the product is loaded and compares it with a pre-registered reference weight for each product. This is to prevent mistakes in product introduction.

  The foot switch 16 has two foot switch buttons, and a shipping pallet placed on the loop conveyors 1A to 1D is replaced with a full pallet full of products and an in-process pallet that continuously inputs products. The pallet sorting means for sorting into two is configured.

  The work instruction device 8 includes a touch monitor 8a and a product barcode reader 8b. The computer 14 includes a control personal computer 14a, a sequencer 14b, and a printer 14c.

Next, the operation will be described.
In the initial state, the empty pallets are stacked in the empty pallet supply device 3, and the pallets are not present in other devices.

  Prior to the sorting operation, the shipping plan information is read into the computer 14. The computer 14 performs address assignment processing of the stacking apparatus 11 for each store of the shipping destination based on the shipping plan.

  Next, the worker 7 is arranged at the product input position 6, and the stacking unit 5 of the product supply pallets containing the products to be sorted is arranged, and the shipping operation is started.

  When the operator 7 causes the product barcode reader 8b of the work instruction device 8 to read the product identification barcode label of the product (type A) to be sorted first, the sequencer 14b of the computer 14 places an order for the product. The store is searched, and the corresponding empty pallet for shipping is automatically and sequentially supplied from the empty pallet supply device 3 to the product input conveyor 2. At this time, the label sticking device 4 sticks the pallet identification barcode label to the empty pallet. Note that the pallet identification bar code label includes address number information corresponding to the store to which the product is shipped.

  The pallet with the barcode label attached is conveyed by the product input conveyor 2 and reaches the product input position 6. Up to this point, the operator 7 is instructed to display information such as the type and number of products to be put on the pallet by the touch monitor 8a of the work instruction device 8.

  The worker 7 puts the product into the pallet based on the instructed information, and when the loading is completed, presses the foot switch 16 disposed on the floor of the worker 7's foot to complete the work to the computer 14. Tell. The foot switch 16 is composed of two foot switch buttons for in-process and full load, and the operator 7 selects whether the pallet into which the product has been loaded is the in-process pallet or the full pallet, and the foot corresponding thereto Press down one of the switch buttons. The in-process pallet is a pallet that has sufficient pallets and can be used for continuous product introduction, and the full pallet is a full pallet.

  The pallet into which the product is loaded is transferred to the lower stage of the product loading conveyor 2 after the foot switch 16 is pressed and conveyed, and there is a stacking device 11 to which the address number of the store to which the pallet is shipped is assigned. Transferred to one of the loop conveyors 1A to 1D.

  The pallet conveyed to the loop conveyor (any one of 1A to 1D) is conveyed in a loop shape and reaches the stacking device 11 having the address number assigned to the store to which the pallet is shipped. A sensor 19 is provided in front of the stacking apparatus 11 (upstream by a predetermined distance), and the address number of the pallet is detected. Based on this address number, a distinction is made between the in-process pallet and the full pallet input from the foot switch 16 to the computer 14. Thereby, when the said pallet is an in-process pallet, it is conveyed downstream as it is and a loop-shaped conveyance is continued. When the pallet is a full pallet, the product pallet stops at the position of the stacking device 11 and is stacked on the stacking device 11 by the lifter mechanism of the stacking device 11. The lifter mechanism may be configured by an arm whose tip is driven up and down to lift the pallet.

  By repeating the above-described series of operations, the introduction of the product is completed on all pallets for the store where the product (product type A) is ordered.

  Subsequently, the operator 7 reads the product identification bar code of the product (product type B) into the product barcode reader 8b of the work instruction device 8 in order to sort out the products (product type B) of different products. Similar to the product type A, the computer 14 searches for a store where the product is ordered.

At this time, based on the data stored in the computer 14, it is searched whether or not the pallet of the store to which the product (product type B) is to be introduced already exists as a work pallet on the loop conveyors 1A to 1D. If the pallet is present, the pallet is transferred from the loop conveyors 1A to 1D to the product input conveyor 2 when the pallet reaches the return downstream end 9 of the loop conveyors 1A to 1D. In addition, a sensor 19 is also provided in front of the return downstream end 9 (upstream by a predetermined distance), and the address number of the pallet is detected. Based on this address number, it is searched whether or not the pallet of the store to which the product (product type B) is to be input. Thus, if the pallet is a pallet of the store to which the product (product type B) is to be input, The product is transferred to the product input conveyor 2, and the other components are conveyed downstream as they are, and the looped conveyance is continued.
On the other hand, when there is no work-in-process pallet on the loop conveyors 1A to 1D, the empty pallet is supplied from the empty pallet supply device 3 as in the case of the product (product type A).

  By repeating the above series of operations sequentially for each product such as product (product type A), product (product type B),..., Product (product type Z), it is possible to obtain all product types and all shipping destination stores. Complete sorting work.

  In the above description, the bar code of the next product (product type B) is read after the product (product type A) has been input in order to simplify the description. However, in actual operation, The reading of the barcode of (product type B) is carried out without waiting for completion of the product (product type A) when the stack unit of the product is supplied in the vicinity of the product input position. By operating in this manner, the in-process pallet of the product (product type B) is searched when the product (product type A) is being continuously input, and immediately after the product (product type A) is completely input. The product (product type B) can be input to the product.

  After completing the sorting operation, a shipping operation for performing the shipping operation is performed. When sorting is completed, the stacking units for each shipping destination store are stacked in all the stacking apparatuses 11, and the height of the stacking units varies depending on the order quantity. Perform leveling operation to keep the stacking height constant.

  For the stacking unit (for store a) stacked downstream of the loop conveyors 1A to 1D, the bottom pallet of the adjacent stacking unit (for store b) is cut out one by one for store a The above stacking unit is sequentially stacked, and the above is repeated until a predetermined height is reached.

  Next, the adjacent stacking unit (for store c) is cut out and stacked into the remaining stacking unit for the store b. If the stacking unit for store c does not reach the predetermined height even when all the stacking units for store b are loaded, by loading the stacking unit of the adjacent stacking unit (for store d), Repeat until the desired height is reached.

  Through the series of operations described above, all the stacking units are stacked again to a certain height, thereby completing the leveling operation and shipping the stacking units from the shipping port 13. At this time, the reverse conveyor of the loop conveyor reverses and ships the stack unit by feeding the stack unit in the same direction as the forward conveyor.

  As described above, in the present embodiment, when all the products are supplied and the products are shipped, the stacking unit 11 and the loop conveyors 1A to 1D are used to separate the stacking units and stack again. By doing so, the stacking height of the shipping stack unit is adjusted within a certain range in accordance with the height of the loading platform of the shipping truck. Therefore, the stacking device 11 and the loop conveyors 1A to 1D constitute a height adjusting means for adjusting the stacking height.

  As described above, in the present embodiment, the products are loaded into each shipping pallet prepared for each of a plurality of shipping destination stores, transported by the loop conveyor, and the full pallets are sequentially stacked. As a result, the products that are sequentially supplied in large quantities can be efficiently sorted every time a product arrives according to orders of small quantities of various products from multiple stores. Further, since the pallet is supplied to the product input position 6 by the loop conveyors 1A to 1D and the product input conveyor 2, it is not necessary for the worker to walk and move for product input. Significantly shortens and improves work efficiency. Further, by connecting a plurality of loop conveyors 1A to 1D to a single product input conveyor and collecting the pallets conveyed by the plurality of loop conveyors 1A to 1D into a single product input conveyor 2, the loop conveyor 1A It becomes possible to create a queue of in-process pallets on the 1D and the product input pallet 2, minimizing the manual waiting time of the worker 7, and improving the efficiency of the product input work. . In addition, since the stacking device 11 is provided above the loop conveyors 1A to 1D, the full pallets are stacked on the stacking device 11 so that only empty pallets and in-process pallets that require product input are transported. In addition, it is possible to increase the transport operation speed and to save the sorting space.

Embodiment 2. FIG.
The second embodiment has the same configuration as the first embodiment and the operation is almost the same, but in order to improve the space efficiency of the merchandise sorting place, pallets for a plurality of stores are mixedly loaded in the same stacking device 11. This is a method of stacking and re-stacking the stacked unit for each destination store at the time of product shipment. In the present embodiment, reference is made to FIGS. 1 to 3 described above, and description thereof is omitted here.

  In the stacking apparatus 11 excluding several stacking apparatuses 11 on the side of the shipping port 13 of the loop conveyors 1A to 1D, a plurality of stores by shipping destination are allocated to one stacking apparatus. For this reason, as shown in FIG. 4, pallets for shipping to a plurality of stores are mixedly loaded in the stacking units 30 and 31. The work is performed in this mixed state during sorting work.

  After the sorting operation is completed, when an empty stacking device 11 is generated on the shipping port 13 side of the loop conveyors 1A to 1D by the leveling operation of the shipping operation, the dividing operation of the mixed loading unit is performed. As shown in FIG. 5, the dividing operation is performed by cutting out the bottom pallets of the mixed loading units 30 and 31 one by one and stacking them again in the empty stacking devices 11A, 11B, 11C, and 11D. Do.

  As described above, in the present embodiment, the same effects as those of the above-described first embodiment can be obtained, and furthermore, by palletizing a plurality of stores for a single stacking device 11 in a mixed manner.

When the in-process pallet arrives at the connection portion 41 from the first loop to the second loop, the pallet identification bar code of the in-process pallet is read by the pallet bar code reader 18 (see FIG. 3) to move to the second loop. The computer 14 determines whether to load or transfer to the first loop return sequence.

  The basic control method for determining the transfer is that the in-process pallet that is scheduled to be put in the product will be transferred to the first loop and the other in-process pallet will be transferred to the second loop. To do. Further, when the pallet is a full pallet and the stacking device 11 of the ship-to store is on the second loop side, the pallet is transferred to the second loop.

  Similarly, when the in-process pallet arrives at the connection portion 41 from the second loop to the first loop, it is transferred to the first loop by reading the pallet identification bar code of the in-process pallet, or the second loop Judge whether to transfer to the column. In this case, it is assumed that the pallet on which the product is scheduled to be transferred is transferred to the return line of the first loop, and the pallet that is not transferred is transferred to the forward line of the second loop. In addition, it is assumed that the pallet is moved between both loops as appropriate according to the traffic congestion situation of both loops.

  As described above, in the present embodiment, the same effects as those of the above-described first embodiment can be obtained, and further, the sorting operation of the shipping pallet can be performed by dividing each loop conveyor 1A to 1D into two blocks.
