Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a packaging device for packaging a product such as fresh food stored in a polystyrene foam tray with a stretch film together with the tray.

(Prior Art) In recent years, in supermarkets and the like, mainly perishable foods that require freshness have tended to be sold in the form of pre-packaged products that are stretch-wrapped together with trays. A stretch wrapping device for manufacturing such pre-packaged products generally includes a carry-in conveyor equipped with a weighing device for weighing the products stored in a tray together with the tray, a lifter for pushing up the product received from the conveyor, and a roll of film. A strip-shaped film fed out from is cut into a predetermined length, and a peripheral edge of the film piece is folded into the bottom surface side of the tray pushed up by the lifter and wrapped, and a packaging mechanism is packaged by this packaging mechanism. It is composed of a discharge conveyor that receives and discharges the product, and a sealing mechanism that is disposed below the discharge conveyor and heat seals the film folded on the bottom side of the tray.

By the way, in this type of stretch wrapping device,
Various sizes of trays will be used depending on the size, shape, quantity, etc. of the products to be packaged, but the length of the film to be cut and the degree of tension are appropriate on the spot. If not set, the film will be excessively strained during the packaging process and the product will be damaged, or the film will not be long enough to cause packaging defects.

Therefore, conventionally, for example, a product master file (hereinafter referred to as a product master) stored in a memory of a control unit equipped in this type of stretch wrapping device.
In addition to the product name and other various kinds of product information, preset packaging conditions for the tray to be used are added, and when the product is designated, the packaging conditions of the corresponding tray are called. According to this, the packaging condition according to the tray used for each product is automatically set, and the above-mentioned problem is avoided.

On the other hand, in the distribution process of products, a pack center such as a vendor that pre-packages raw materials for a plurality of stores may intervene, and the stretch wrapping device for such a vendor has a memory of a control unit of the device. In addition, a tray master file (hereinafter referred to as tray master) that contains the packaging conditions set in advance corresponding to the size of the tray, and a product master that stores the product name, price and other fixed data attached to the product for each product, Enter a product number, store number, and tray number used for that store so that a store master file (hereinafter referred to as store master) that stores store names and other variable data for each store can be registered. As a result, the packaging conditions of trays used for products for each customer are called.

(Problems to be solved by the invention) However, in the conventional stretch wrapping machine with vendor specifications, the packaging condition of the tray to be used is set by manual input as described above. If the trays are different, the tray number must be input again each time the store changes, which not only causes a problem in work efficiency, but also increases the risk of defective products due to input errors.

The present invention addresses the above-mentioned problem in a vendor-specific stretch wrapping machine, and it is possible to automatically set appropriate wrapping conditions even when different types of trays are used in different stores for the same product. With the goal.

(Means for Solving the Problems) That is, the packaging apparatus according to the present invention is configured to include a packaging means for packaging the products stored in the tray by the stretch film, and stores the type of tray to be used for each store. Tray type storage means for each store, a product-specific tray storage means that can register a plurality of used trays corresponding to each type of used tray for each product, and a packaging condition set for each tray size. Packing condition storage means, product designation means for designating a product, store designation means for designating a store, and the type of tray used at the designated store is read out from the tray storage means used for each store, and the type of tray read out The tray to be used corresponding to is selected from the tray storage means for each product, and the packaging condition of the selected tray size is stored in the packaging condition storage means. And a control means for reading out from the device and operating the packaging means.

(Operation) According to the above configuration, the packaging condition of the tray used for the product for the store is automatically set only by specifying the product and the store, and therefore the tray for the store is manually set. The work efficiency is improved as compared with the case of setting by operation, and the risk of defective products due to input errors is reduced.

Moreover, when the types of trays used are common in each store, they can be used collectively in one group, so that data can be shared and the memory capacity can be significantly saved.

(Example) Hereinafter, an example of the present invention will be described.

As shown in FIG. 1, the packaging device 1 has a carry-in conveyor 3 provided with a weighing device 2 for weighing the weight of the product Y stored in the tray X, and a product Y received from the carry-in conveyor 3 that can be lifted and lowered. The lifter 4 and the strip-shaped film 5 pulled out from the roll 5a of the film 5 are cut into a predetermined length, and the peripheral edge of the film piece is folded into the bottom surface side of the tray X pushed up by the lifter 4.

Further, a label issuing machine 14 integrated with this is provided.

Then, the packaging device 1 has a packaging mode in which only the packaging work is performed on the products Y stored in the tray X, a pricing mode in which the weighing and pricing processes are performed on the packaged products Y, and a packaging mode. Packaging that consistently carries out operations from price to pricing
It is possible to switch to one of the pricing modes.

Next, the system configuration of the packaging device 1 will be described with reference to FIG. 2. First, the control unit 12 includes a CPU 15 that executes arithmetic processing and various control processing, a ROM 16 in which operation programs and the like are stored in advance, an arithmetic result and It has a rewritable RAM 17 in which other data is temporarily stored and an input / output interface 18 for input / output. And the above CP
The U15 is provided in the operation unit 11 of the console box 9 and has a key input unit 19 for inputting various control commands and numerical values, a system switch 20 for turning the system ON / OFF,
Various signals from a start switch 21 for turning ON / OFF the packaging device 1 and a mode changeover switch 22 for selecting one of the above modes are input through the input / output interface 18, and in accordance with these signals, The data in ROM16 is transferred to RAM17, various data read from ROM16 and RAM17 is output to the display 10, and the product Y based on the weighing signal from the weighing instrument 2 also taken in through the input / output interface 18 The price is calculated and the data is written in a predetermined area of the RAM 17 or a print signal is output to the label printer 13 via the input / output interface 18, and the product name and the store stored in the RAM 17 in advance. The weight and price of the product Y as well as the data such as the name are printed on a label and issued.

Further, the RAM 17 is provided with a tray master, a product master, and a store master.
As shown in FIG. 3, for each tray X, the tray number and
The packaging conditions for using the tray X, a tray master having a tray name, etc. are registered, and the product master has a product number and a product name for each product Y as shown in FIG. And a plurality of trays used for each product Y are registered.

For example, in the case of a product to be delivered to each supermarket of group A, the tray number (10) used for the product specified in that group is registered, and in the case of a product to be delivered to each supermarket of group B, the The tray number (20) used for the product designated by the group is registered, and further, in group C, the tray number (30) used for the product designated by the group is registered.

Furthermore, as shown in FIG. 5, the store master stores the store number of each store, the store name, and the type of tray used in the store, that is, the store is A.
When belonging to a group, the group name (A) is B
When belonging to a group, the group name (B) is
When belonging to the C group, the group name (C) is registered respectively.

Next, an operation example of the packaging device 1 will be described.
When the operation mode is selected by the operator operating the mode selection switch 22 after turning on the system switch 20, the CP
After setting the code indicating the selected mode in the work area of RAM17, U15 waits for the next execution command input.

In this case, assuming that the packaging / price mode is selected as the operation mode, the CPU 15 executes the control process according to the flowchart of FIG.

That is, the CPU 15 first determines the input of the product number in step S ₁ , and after entering the product number, proceeds to step S ₂ and waits for the input of the store number. And when the store number is entered,
Based on the store number and the product number, first, the group name G _T to which the corresponding store belongs is read from the store master.
In this case, when No. 1 is input as the store number, the code indicating the A group is read as the group name G _T.

Then, the CPU 15 executes step S ₄ to execute the group name G
It is determined whether _T matches the A group, and if YES is determined, the product master is searched, the tray number of the product used in the A group is read from the area of the designated product Y, and the work on the RAM 17 is read. Set in the area. In this case, if the product number 1 is input in step S ₁ , the tray number 10 is set as shown in FIG.

On the other hand, if the CPU 15 determines NO in step S ₄ , it proceeds to step S ₆ to determine whether the group name G _T matches the B group, and when YES, executes step S _7. while reading the tray number of items belonging to the B group from goods master, the group name G _T proceeds to step S ₈ when the result of determination is NO, it is determined whether they match the C group, determines that YES step the tray number belonging to group C running S ₉ read from the goods master. When it is determined that the tray is not in the C group, the CPU 15 is forced to read the tray number belonging to the A group.

Next, the CPU 15 searches the tray master with the tray number set in the work area of the RAM 17 as a search code, and when the tray number is found, reads the packaging conditions from the area of the number and sets it in the work area. At the same time, the name of the tray X is displayed on the display 10 so that the operator can start the switch 21.
Wait for input operation. (Step S ₁₀ ~S _13). Then, upon detecting the ON operation of the start switch 21 by the operator executes with packaging and values processed sequentially (step S _14). In this case, when No. 1 is entered as the product number and No. 1 is entered as the store number,
As described above, the packaging mechanism 6 operates under the packaging conditions corresponding to the tray number 10, and the product Y taken in from the carry-in conveyor 3 is packaged.

Incidentally, CPU 15 when the search error occurs in the search processing tray master in step S ₁₀ is made to branch from step S ₁₁ to step S ₁₅ so as to display a predetermined error message on the display 10.

As described above, since the packaging condition is automatically set only by designating the product and the store, it is not necessary to input the tray number even if the trays used for the same product are different.

In addition, in this embodiment, the group of trays X registered in the product master is three, but the number is not limited to this.

(Effect of the invention) As described above, according to the present invention, the packaging condition of the tray for the store is automatically set only by designating the product and the store. Therefore, the packaging condition can be manually operated. The work efficiency is improved as compared with the case of setting, and the risk of defective products due to input errors is reduced.

Moreover, for stores that share the same type of tray, 1
Since the tray information gathered in groups can be used,
There is also an advantage that the data is shared and the memory capacity is greatly saved.
