Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology delivers each cold and hot product to each store according to each store's order for products ordered from multiple stores such as Supermarket I stores. A picking system that selectively takes out ordered cold and hot products from shelves (product shelves) such as flow racks, transports them on a conveyor, and stores them in containers such as containers for each store; It belongs to the field of sorting system technology, in which cold and hot products of each type are taken out from containers such as containers conveyed by a conveyor and stored on shelves such as flow racks in a corresponding manner on the product shelves of each store.

<Summary of the gist> The invention of this application is a box in which low-temperature products such as fried shrimp, shumai, etc. are placed on a floor rack in a housing of a refrigerator, freezer, etc. that is kept at a predetermined low temperature. A conveyor is operated at the front of the housing to convey the containers, etc., and each ordered item is transferred from the 70-rack container to the container conveyed on the conveyor. Picking and storing of products, conversely, sorting of products that are stored in containers on a conveyor and transported by type, and selectively stored by type from the containers into boxes of different types of flow racks. This invention relates to a low-temperature product processing method for transferring products between the flow rack and a container on a conveyor, and a device directly used in the method. However, the dissipation of external cold air to the outside is prevented by using vinyl curtains such as strip-shaped loop type, air curtains, etc., and the housing is closed by shutters such as slat type during suspension periods when product delivery is not performed. A method for processing low-temperature products, in which product delivery data is electrically displayed in the product delivery area, and workers, etc. perform product delivery processing according to the displayed product delivery data. and an invention related to a device.

<Prior art> As is well known, as civil society improves, consumer life becomes significantly richer and the variety of products handled in the secondary market becomes richer. The dynamic processing of high-mix, low-volume products has expanded from the static processing of high-mix, low-volume products, and the distribution process has changed from the traditional high-mix low-volume processing to the largest material stock of products in the distribution process. As a result, the amount of intermediate stock has been reduced by changing to a dynamic distribution system in which products are moved and processed, and as a result, the processing of products in the distribution market is becoming more and more systematic and rapid. Moreover, there is an increasing demand for the process to be carried out accurately and under safe control conditions without compromising the quality of the product.

In particular, food products have a large impact on people's health, nutrition, hygiene, etc., so it is important to maintain quality control and precision preservation at the chronological stage from the producer to the consumer's consumption. Strictness is now required and, therefore, low-temperature products such as frozen foods and refrigerated foods whose preservation status is effectively maintained over time, ranging from product processing of fresh foods and raw foods immediately after production, to is becoming widely available.

However, when the low-temperature products are foods, unlike ordinary industrial products, they undergo complicated processing processes such as weighing, journalizing, and pricing in the distribution market, so they are exposed to intense temperatures. In many cases, the product undergoes a change in state, so reducing the time-based change in state during the processing process, especially during the process of transporting from the distribution center to each store, etc., eliminates the need to change the low temperature state. As a result, the selection and sorting of products by type from housings such as freezers and refrigerators to each store, picking for shipping and reverse sorting, has become more and more demanding. Consideration must be taken to prevent cold air at a predetermined low temperature from escaping outside the housing, and in addition, when transferring products from the housing of the refrigerator or freezer to the conveyor, the transfer must be carried out smoothly inside and outside the housing. There is.

Since these conditions conflict with each other, conventionally, in order to maintain the inside of the freezer or housing at a predetermined low temperature, workers have to go in and out between the housing and the conveyor when transferring products to and from the conveyor outside the housing. It moves, and even goes around between shelves such as flow racks in the housing.
Picking and sorting of the low-temperature products was done manually based on slips.

<Problems to be Solved by the Invention> Therefore, as mentioned above, in order to maintain the low temperature inside the housing at a predetermined level, keeping the shutter etc. in the closed state at all times makes it difficult for workers to receive goods between the inside of the housing and the conveyor. Air curtains, etc. were installed to provide support for the handover work, but due to the frequent entry and exit of the housing by workers, there was some amount of low-temperature cold air inside the housing escaping to the outside of the housing. However, due to the unavoidable point, there is the disadvantage of high strike prices from an economic standpoint such as power costs.
Also, for example, if the low temperature inside the refrigerator is 5°C and there is a temperature difference of 18°C outside the housing, there is an inconvenience that transporting the refrigerator will not affect the health of the worker due to entering and exiting the housing and the impact cannot be ignored. In addition, there is a risk that dust, etc. may enter and exit unexpectedly due to the movement of air as workers move in and out of the housing, and if handling procedures are unfamiliar, low humidity products may be There was also a disadvantage that the processing time could fluctuate over time and the low temperature state of low temperature products could deviate from the set low temperature range.

Therefore, in the conventional mode, for example, in the conventional mode of picking from a stock center such as a frozen food warehouse to each store, or in the conventional mode of sorting to shelves such as 70-racks for each store at the center, automatic System 5 of warehouse method via computer! ! l! There were problems that could not be solved by science and technology.

<Object of the Invention> The object of the invention of this application is to provide a method for picking and sorting between the housing of a refrigerator or freezer, etc., and the transport container of a conveyor for frozen and refrigerated foods such as fried shrimp based on the above-mentioned prior art. Solving the problems of handover processing is a technical issue, and in consideration of the special stocking conditions of low-temperature products such as frozen and refrigerated foods, it is necessary to improve the handling of low-temperature products between the housing and the conveyor not only during stocking but also during picking and sorting. (Even during the transfer process, the cold air inside the housing is prevented from escaping to the outside of the housing as much as possible,
While maintaining the low-temperature state of low-temperature products, the transfer work between the housing and the transport container on the conveyor can be carried out smoothly. 0 It is possible to take into consideration the low temperature maintenance state in the processing room, and in addition, insurance hygiene management can be performed reliably by maintaining the low temperature state of the product, and product processing data from the administrative system is used instead of primitive work based on slips. The purpose of the present invention is to provide an excellent low-temperature product processing method that enables picking and sorting operations to be performed reliably in accordance with the instructions and that is beneficial to the field of product movement technology in the distribution industry, as well as equipment that can be used directly in the method. .

<Means/effects for solving the problem> In order to solve the above-mentioned problem, the structure of the invention of this application, which is based on the scope of the above-mentioned patent claims, is to provide low-temperature products such as frozen and refrigerated foods such as fried shrimp. If the product shelves such as Florack installed inside the housing of a refrigerator or freezer at a predetermined low temperature are divided into stores, selectively sorting products into each column, or conversely, sorting to each store can be done by delivery. When picking products by product, a conveyor such as a belt conveyor is operated at the front of the housing of the refrigerator or freezer to transport containers such as containers. The product delivery data of low-temperature products accumulated by type on shelves such as 70-racks in each row of each row are displayed on the front or top of the relevant shelf using a photoelectric product delivery data display mechanism for workers to display. visually inspects and follows the displayed data, picks the low-temperature product from containers on shelves such as flow racks to containers on a conveyor, and delivers the product without relying on slips or the like or requiring any skill. , or sort the low-temperature products in containers transported by a conveyor to containers on shelves such as 70-racks organized by each store in the housing according to display data, and when picking and sorting, the 70- In front of shelves such as racks, install a strip-shaped curtain made of flexible material such as vinyl chloride, or use an air curtain to prevent the cold air inside the housing from escaping to the outside. The conveyor side of the housing is closed by a shutter when the transfer process is stopped.
The inside and outside of the housing are shut off to completely maintain the low temperature and sanitary conditions inside the housing, and picking of low-temperature products from shelves such as flow racks inside the housing to the conveyor and reverse sorting are carried out at hand. When switching, the gradient set of shelves such as flow racks can be changed freely, so that each store can selectively use picking and sorting in two ways using one system plant, and the shutter and shutter guide A heater such as a defrost heater may be installed on one or both sides to prevent shutter opening from being hindered by freezing of the shutter, and from a system perspective, a product delivery data display mechanism is installed in the housing prior to container transport on the conveyor. A technical measure has been taken to display the product delivery data, and to erase the data display after the delivery operation is completed so that the conveyor is advanced by one zone.

<Example> Next, an example of the invention of this application will be described below with reference to the drawings.

3- The illustrated embodiments are cold foods such as frozen foods such as fried shrimp and crab croquettes, fresh foods such as dried vegetables, frozen foods such as ramen and meat buns, and refrigerated drinks such as juice and milk. This is a mode in which products are picked and sorted for each store, and 1 shown in FIG. 1 is a low-temperature product processing device that is the center of one of the gist of the invention of this application. , and a pair of front and rear freezers on both left and right sides of the belt conveyor 5 interposed between the relay conveyor 3 and the front carry-in conveyor 4, and refrigerator housings 6.7.6', ? ' is attached.

A label printer 8 is provided facing the conveyor 5 near the base of the refrigerator housing 7.7 (near the delivery side), and an electrical equipment room 9 is also provided, and the base of the refrigerator housing 7' on the opposite side is A mechanical equipment room 8' is provided.

In addition, 10 is a container such as a container, and the conveyor 4.5 is formed into two stages, upper and lower, with the lower stage being for conveyance, and
The upper stage is a conveyor for returning empty boxes, as shown in Figure 2.

Thus, a predetermined number of multiple rows of product shelves, such as 4 rows, 5 rows, 6 rows, etc., are formed along the conveyor 5 in each housing 6, 6', 7.7'. In each row, the upper and lower four flow racks 11.11...
As shown in FIG. 1, it is formed on a frame 12.

Therefore, each flow rack 11 has as many as the types of low-temperature products to be processed, that is, the number of stages multiplied by the number of rows.As shown in FIG. 9, each flow rack 11 has a pair of flow rack frames 13. rollers 14, 14, . The slope is on a slope.

And, inside the frame 12, there are upper and lower sections for each row! A bar 16 is provided as a collar.

In addition, the flow rack frames 13 and 13 at each stage are frame 1.
2 via a pin 17, and its outer end is pivoted to an elevating frame 5 provided along the frame 12 via a pin 19, and the elevating frame 18 is a device frame. The handle lever 21 is connected via a pin 22 to the inner end of a handle lever 21 which is pivotally provided via a pin 20 to the inner end of the handle lever 21 .

Then, as shown in FIG. 11, the handle lever 21
A stopper pin 24.23 is provided on the device frame with notches 23.
24, the handlebar 21 can be engaged with the flexure of the handlebar 21 to maintain the stopped posture.

The handle lever 21 and its handle 21' constitute a mechanism for switching the flow rack 11 between a downward slope set for picking and an upward slope set for sorting.

Incidentally, bars 16' serving as stoppers are provided at the outer ends of the flow rack frame 13 in correspondence with each other.

As will be described later, during the picking process, by pushing the handle 21' of the handle lever 21 downward through the pin 20, the frame 18 is raised and lowered by a predetermined stroke, and each flow rack frame 13 is moved up and down through the pin 22. As shown by the solid line in FIG. 11, the container is inclined gently downward at a certain angle toward the conveyor 5, and the cardboard box 15 containing a predetermined type of low-temperature product is forwarded by its gravity. Then, the tips of these boxes are locked with the bar 16 of the stopper, and by removing the empty box, the following cardboard boxes 15 are sequentially advanced toward the bar 16, and the work is completed as shown in FIG. The worker 25 can freely pick containers from the flow rack 11 onto the conveyor 5 for each store into the container 10.

Then, as shown in Figure 1.7, the bar 1 of each stopper
From 6, a rectangular curtain 27 made of a flexible material made of vinyl chloride with slits 26, 26... is connected integrally at the rear end and hangs down in a loop style, and its lower end The housings 6, 6' and 7 are partially overlapped by the curtain 27 below, making it easier for the operator 25 to perform the picking process as shown in FIG.
．． It is possible to prevent the cold air inside the housing 7' from escaping to the outside of the housing 7 leg as much as possible even during the picking operation.

The curtain 27 serves as a low temperature maintenance mechanism.

Therefore, by lifting the handle 21' upwardly through the pin 20 as shown by the dotted line in FIG.
The lifting frame 18 is lowered to a predetermined level via the pin 17, so that each flow rack frame 13 is set upwardly in the direction of the conveyor 5 via the pin 17, so that each store from the containers 10 on the conveyor 5 is Florac 1
1 to facilitate the sorting process.

Also, conversely, the handle 21' allows you to
By arranging the flow rack 11 as a vine shelf downward to the conveyor 5, picking of containers 10 for each store by the conveyor 5 is performed.

As shown in FIG. 4, each housing 6.6', 7.
A suitable freezer 18 is installed on the ceiling inside the housing 7', and a circulation fan 29 is installed at the rear of the freezer 18 to maintain a uniform low temperature inside the housing.

Further, a work space 30 is provided below the fan 29 to facilitate maintenance, inspection, maintenance, etc., and doors 31 for maintenance, etc. are provided in each row on the rear wall portion. .

It goes without saying that the working space 30 and the door 31 can also be used for sorting the flow racks 11 for each store in each row from the back.

As shown in FIG. 4, a shutter mechanism 32 is provided at the top of the conveyor 5 as a low temperature maintenance mechanism when low temperature product delivery processes such as picking and sorting are stopped. The shutter guide is formed with a U-shaped cross section and stands upright in an inverted shape. Inside the shutter guide, slat type shutters 34, 34, etc., which can be moved freely via rollers 36, are installed via a predetermined number of joints 35 They are connected and can be raised and lowered, and opened and closed.
Furthermore, as shown in FIG. 4.6, the winding device 32 has an endless winding wire 39 that engages with a winding drum 38 provided at one end of a shaft 37 that inserts a torsion spring 36 therein. And, via a chain 42 stretched between sprockets 1 to 40 degrees 41, a shutter 34 can be opened and closed at the front of all the upper and lower flow racks 11, 11..., that is, on the conveyor 5 side, When not performing low-temperature product delivery processing such as picking or sorting, the housings are closed to prevent the cold air inside the housings 6.6' and 7.7' from escaping completely to the outside, and to maintain low temperatures. It is designed so that it can be measured.

In addition, when receiving such low-temperature products, if there is a risk that the shutter 27 may unexpectedly freeze water droplets against the shutter guide rail 33 during the non-processing state of the transfer operation, the next low-temperature product transfer processing operation should be carried out. Therefore, as shown in FIG. 5, in this embodiment, an appropriate defrost heater 43 is provided in the part of the shutter guide 33 where the shutter 34 is in the closed state position, so that the shutter during the next zero operation will be prevented. 34 is guaranteed to open and close smoothly.

Also, depending on the design, it is possible to provide a defrost heater not on the shutter guide 33 side but on the shutter guide 33 side of the shutter 34, or on both sides, and this is just a design issue. be.

As shown in FIG. 4, at a predetermined height above the shutter guide 33 70 of the shutter 34 and the uppermost part of the rack 11, photoelectric product transfer is carried out via brackets 44 in each row. A data display mechanism 45 is provided and is faced at an inclined angle for easy viewing by the worker 25, and in each row there is a fluorescent lamp indicator 46 as shown in FIG. A repeater is installed and will be described later, and it is displayed that, for example, 4 low-temperature products in the second stage of the row are to be picked (or picked), and the picking (or picking) is performed.
When the work is completed, the worker 25 presses a push button 47 serving as an erasing mechanism, so that the transfer data display on the indicator 1 46 disappears.

As shown in FIG. 3, the operating system of the low-temperature product processing apparatus 1 is such that a computer-operated ordering mechanism 48 at each supermarket store is connected to a computer-operated ordering mechanism 49 at the collection and delivery center, and a repeater 50, the label printer 8 and the conveyor 5 are operated, and as shown in FIG. When picking and receiving low-humidity products, by pressing the push button 47 after the transfer process is completed, the product transfer data for the low-temperature products in the relevant stage of the indicator 46 is erased and the data on the housing 6 of the refrigerator or freezer is cleared.
6', 7', 7' and 7', the conveyor 5 moves to 1 zone after the picking and passing process of all the low-temperature products in each row is completed and the indicator 46 of the low-temperature display mechanism 45 for all the rows is cleared. In other words, the picker is moved forward by the pitch of the store valve, and the handing over process is completed.

2 In the above-described configuration, first, when a predetermined product is accumulated by type in each stage of the flow racks 11 in each row of the housings 6.6' and 7.7' of the low-temperature product processing apparatus 1 by filling process, the empty state is housing 6.6', 7.7'
The worker 25 operates the freezer 28 and the fan 19 to bring the interior to a predetermined low temperature state, and when the freezer control device (not shown) detects that the low temperature state has been reached, the worker 25 closes the rear door 31. Hearing this, he entered the work room 30,
As shown in FIG. 11, the handle 2 of the handle lever 21
1' to lower the lifting frame 18, each flow rack frame 13 is tilted upward toward the outside, that is, toward the conveyor 5, as shown by the imaginary line in FIG. A standby state for filling operation is prepared.

Therefore, when a container containing a predetermined product is conveyed from the carry-in conveyor 4 via the computer-based instruction mechanism 9, a barcode label is affixed to the container, and the product delivery data of the corresponding column and stage of the product is displayed. For example, the indicator 46 of the mechanism 45 displays the number of stages of the product and the number of products to be filled in the stage. The worker 25 waiting there visually checks the display data of the indicator 46, takes out the product from the container 10 of the conveyor, and inserts the product into the container 15 of the corresponding flow rack 11 through the slit 26 by scraping the curtain 27. Inject the specified type of product.

In such a filling operation, the opening/closing wire 39 raises the shutter 34 along the guide rail 33 via the drum 38, the chain sprocket 40, and the torsion spring 36 to open the side of each housing closer to the conveyor. At that time, as mentioned above, since the defrost heater 4.3.43 is provided in the shutter guide 33 and has a defrost effect, the freezer 2
Even if the inside of the housing becomes cold due to 8, freezing between the shutter 34 and the guide rail 33 is prevented,
The shutter 34 is opened smoothly by the wire 39.

Therefore, even if the product filling work to the various types of flow rack shelves is being carried out while the transfer process is being carried out, the cold air inside the housings 6.6' and 7.7' is discharged from each curtain 27. This prevents it from escaping to the outside as much as possible.

In addition, as mentioned above, instead of the curtain 27, the air force tens 2
Setting it to 7 is within the range of design changes.

In each of the flow racks 11, the flow rack frame 13 is set so as to be inclined outwardly and downward, so that when each container 15 is filled with the relevant type of low-temperature product, its gravity By roller 14.14
The worker 25 sets the empty box on the upper side of the conveyor 5 on the flow rack frame 13 and performs the filling/handling process for each product type. Continue working.

In this way, when the transfer process is completed, the worker 25 presses the button on the product transfer data display mechanism 45 to receive and receive the filling of the products in the containers conveyed on the conveyor 5 for one zone into the flow rack 11. By pressing 47, the data display on the indicator 46 is erased, and when the erased display on all stages is erased, the conveyor 5 is moved by one zone by the computer's instruction mechanism 49, and the conveyor 5 is moved for each next product. Repeat filling.

In this way, it is ensured that the flow racks 11 for each product in each tier in each housing 6.6', 7.7' are filled with the corresponding product as designed, and that the Even if the housing is heated, the dissipation of cold air inside the housing is prevented as much as possible, and the intrusion of dust and the like is also prevented, so that the predetermined low temperature and sanitary conditions inside the housing are sufficiently maintained.

When all the flow racks 11 for each product type in each housing 6.6', 7.7' are filled with the corresponding type of product, the shutter 4 is lowered along the guide rail 33 via the wire 39. Then, the housing is closed, and the picking reception for the next store is prepared for the transfer operation.

Therefore, when picking ordered products for each supermarket store, the wire 39 is used)
Contrary to the book, the worker moves up the shutter 34 along the guide rail 33 to open it, opens @31 on the back side, enters the work chamber 30, and pulls down the handle 21' shown in Fig. 11. , the notch 23 of the handle lever 21 comes off the stopper 24 and the lifting frame 18
increases to a certain level, and the flow rack frames 13 simultaneously move toward the conveyor 5 via the pins 17 in a downward slope position as shown by the solid line in FIG.

Then, when the empty container 10 for each store is conveyed to the conveyor 5 via the carry-in conveyor 4, the barcode label of the store is attached by the label printer 8, and the barcode label for each store is attached to each housing 6.6', 7.7. The indicator 46 of the product delivery data display mechanism 45 provided at the top of the screen displays the row number and picking quantity of each product type, and the worker 25 visually observes the product delivery data display on the indicator 46. The products on that stage are then taken out through the slits in the curtain 27 and stored in the containers 10 on the conveyor 5.

Then, when the pick-up operation from the container 15 of the flow rack 11 of each stage to the container 10 of each store for the relevant type of low-temperature product is completed, the worker 25 presses the push button 27 of the product weighing data display mechanism 45. By pressing , the display data of the indicator 46 is erased, and when all the display data of the product delivery data display mechanism 45 is erased, the computer instruction mechanism 49 causes the conveyor 5
moves forward by one zone, that is, by one store, and the picking receiver for the next store's container 10 performs wave processing.

In this way, the worker 25 can perform work in and out of the housings 6.6' and 7.7' using other pipe slips by visually observing the product delivery data display on the indicator 46 of the overhead product delivery data display mechanism 45. Picking and receiving of ordered low-temperature products from the flow rack 11 for each store can be carried out quickly and smoothly by hand without having to do anything, and the curtain 27 allows the cold air inside the housing to dissipate to the outside. The low temperature condition inside the housing is maintained, and the intrusion of dust and the like into the housing is also prevented.

Then, during the lunch break or between the end of work and the start of work the next morning, the shutter 34 is pulled down along the shutter guide 33 to close each housing and the defrost heater 43 is operated in the same manner as described above. This sufficiently prevents the shutter 34 from opening next time it freezes.

The low-temperature state of each low-temperature product in each housing is sufficiently maintained.

Then, when all the picking work is completed, the next time the sorting work is done on the flow rack shelves for each store, the worker will move to the back door 3.
1 to enter the working chamber 30, and then move the flow rack frame 13 by the handle lever 21 via the handle 21'.
In preparation for sorting, the sorting tray is placed in a downward slope position toward the outside and performs the handing process.

When the products of each type are stored in the containers 10 of the conveyor 5 and transported, the worker 25 visually checks the indicator 46 of the product delivery data display mechanism 45 and moves them to the rack 70 on the shelf of a predetermined store. Sort the products by type.

9 It goes without saying that the embodiment of the invention of this application is not limited to the above-mentioned embodiments. For example, the picking operation is performed using the inner conveyor, and the filling operation is performed using the outer door 3.
4 may be opened and the disinfection may be carried out from within 30, and various configurations may be adopted in which a sterilizing light is attached inside each housing.

Also, in terms of design changes, as mentioned above, there are 71 changes regarding curtains.
An air curtain type may be used instead of the two types, an automatic type may be used instead of a manual type for changing the gradient of the flow rack, and the defrost of the shutter may be provided on the shutter side instead of the guide rail side as described above. Of course, it is also possible to make the product shelves stand up, and the product shelves are not limited to the floating type, but can also be flat shelves or simple shelves, and products may be placed directly in each column without a cardboard box. This is within the scope of design changes.

It should be noted that, prior to pasting the label in the printer 8 and transporting the container 10 by the conveyor 5, processing data display 0 of the quantity of the relevant type of product in each stage is performed on the indicator 46 of the product delivery data display mechanism 45. processed by computer.

Furthermore, it goes without saying that the product delivery data display mechanism may be arranged for each row or each stage, and it goes without saying that such technology is within the scope of design changes. .

Furthermore, the product delivery data display mechanism is within the range of design changes, such as changing to a cathode ray tube system or a liquid crystal television system.

The selective arrangement of the refrigerators and freezers in the housing along the conveyor can be changed depending on the application, and the cooling mechanism such as the freezer can be controlled by temperature. This is within the scope of design changes.

<Effects of the Invention> As described above, according to the invention of this application, basically the picking of low-temperature products such as frozen and refrigerated foods at each Supermarket store, etc. Product transfer processing between product shelves such as housing flow racks at the collection and delivery center and containers on conveyors, such as sorting and filling products on product shelves, is selectively performed by one plan 1 system. The advantage is that picking, sorting, or product filling can be freely selected, which is a highly flexible and excellent effect.

Moreover, even during picking, sorting, product filling, receiving, and handling operations, the cold air inside each housing is prevented from escaping to the outside, and the low temperature inside the housing can be maintained, thereby improving product quality control. This has the effect that the cleaning is carried out sufficiently, and also has the excellent effect that dust and the like are prevented from entering the housing, and sanitary conditions can also be maintained.

Therefore, cold air dissipation can be prevented by closing the shutter not only during picking, sorting, and product filling, but also during non-processing, thereby maintaining the low temperature inside the housing. The effect is that it can be done.

Therefore, the picking and sorting of frozen products such as refrigerated and frozen foods, and the receiving and filling of products can be carried out as designed while ensuring quality control and sanitary conditions. Ru.

Therefore, when receiving processing such as picking, sorting, and product filling, the product weighing data is displayed prior to the conveyor at the time of delivery, and after the product is processed, the display is erased at the product processing section. In order to operate the conveyor for each zone, it is possible to reliably fill the product shelves of each flow rack and the like, and to sort the products using the shelves as stores with the same accuracy as picking for each store.

In the low-temperature product processing equipment, the opening of each housing to the transport conveyor is handled by an air curtain or a run-type curtain made of a flexible material made of vinyl chloride, etc., during the transfer process. Because picking, sorting, and product filling are carried out, the dissipation of cold air inside the housing can be prevented even when low-temperature products are put in and taken out. Because it can be closed, and because product shelves such as flow racks are equipped with a switching mechanism between a downward slope set for picking and an upward slope set for sorting and product filling, it is possible to process low-temperature products. Because the equipment plant can be used for picking, sorting, and product filling, the initial cost of installation can be reduced, and workers can use the product delivery data display mechanism. Handling can be done just by visual inspection, there is no need for other personnel's skill, there is no need to rely on slips, etc., and there is no need to go in and out of the low-temperature housing, which improves health management. It also has a positive effect.

As described above, picking, sorting, and receiving/viewing processing of product filling can be done simply by visually checking the display data of the product delivery processing display mechanism, so it is possible to check the rows of product shelves in each flow rack while viewing the slip. This eliminates the need for cumbersome work such as having workers go around between stages, and it is only necessary to work along the conveyor, which is extremely efficient and has the effect of improving work accuracy accordingly.
