Description

DETAILED DESCRIPTION OF THE INVENTION The present invention automatically weighs products, such as fruits and vegetables, fish and shellfish, while they are being packaged for retail use, and also displays the price of the weighing results printed on the product after packaging is completed. This relates to weighing, packaging, and price tags that automatically attach labels.

Conventionally, when products are wrapped in film and weighed and priced, the film-wrapped products are automatically transported from the packaging device to an automatic weighing and pricing device for weighing and pricing, i.e. , the packaged product is weighed, the price is printed on the label, and the printed label is attached to the film packaging.

Therefore, in this case, a packaging device that places the product on a tray and wraps it in film, and an automatic weighing and pricing device that automatically weighs the product and affixes a printed label to the film package of the product are required. This not only increases the size of the entire device, but also has drawbacks such as increased equipment costs.

The purpose of the present invention is to measure and measure products during packaging.
The object of the present invention is to eliminate the drawbacks of the prior art by providing a weighing, packaging and pricing device that can complete pricing.

Next, the configuration of a first embodiment of the present invention will be explained with reference to FIGS. 1 to 4.

On the supply side of a weighing, packaging, and pricing device (hereinafter simply referred to as a packaging device) 1, a tray 2 with products 3 such as fruits and vegetables or fish and shellfish placed thereon is fed into the packaging device 1. Chain conveyor 5,
That is, the conveyor surface 10 is rotated through the chain wheels 7 at both ends of the conveyor frame 6, and the conveyor frame 6 is rotated through the conveyor frame 6 at the left and right positions of the conveyor frame, through the pressing rods 9 attached between the chains 8.
A chain conveyor 5 is attached to supply the above packaged items 4 to the packaging device 1, and the chain conveyor 5
An automatic weighing device 12 is attached to the center in the longitudinal direction via a support stand 11, and the upper surface portion of the weighing pan 13 with a conveyor of the automatic weighing device 12 protrudes above the conveyance surface 10 of the chain conveyor 5.
The chain 8 is guided by the chain wheel 14 attached to the support base 11.
It passes through the center of the

When the intermittent drive device 15 for the chain conveyor 5 is operated in this state, the push rod 9 moves one pitch at a time to the position shown in FIG. The object to be packaged 4 is moved one pitch at a time to the weighing pan 13.
When it reaches the end of the weighing pan 1, the object to be packaged 4 is moved onto the weighing pan 1 by the rotation of the belt conveyor 16.
When the object 4 moves slightly above the weighing pan 13 along the belt conveyor 16 and reaches the center in the longitudinal direction of the weighing pan 13, the belt conveyor 16 automatically lowers and the object 4 moves slightly above the weighing pan 13. The weight of the packaged item 4 is automatically measured while being placed on the top surface.
Automatic weighing of the next packaged item 4 is started by the lifting of the belt conveyor 16 upon completion of weighing and the movement of the push rod 9 due to the intermittent drive of the chain conveyor 5.
Moreover, the packaged object 4 that has been weighed first is supplied from the chain conveyor 5 to the pedestal 17 of the push-up supply mechanism detailed in the specification of JP-A No. 52-126388, and then It is wrapped in a film by the same mechanism as described in the specification of No. 51-42049, and is delivered to the outside via the delivery guide mechanism 18.

Further, as shown in FIGS. 1 to 3, a pricing device 19 that operates in synchronization with the automatic weighing device 12 is located above a delivery guide mechanism 18 that serves as a delivery means for transporting film-wrapped products. When the packaged item 4 is attached and passes under the pricing device 19, a label on which the weight of the packaged item 4 weighed by the automatic weighing device 12 and a price corresponding to the weighing result is printed is attached to the packaged item. 4 can be pasted onto the wrapped film.

In addition, in the case of this embodiment, the automatic weighing device 12 has a separate frame and is incorporated into the packaging device 1 main body without being directly connected to the chain conveyor 5. The automatic weighing device 12 and the pricing device 19 can be easily removed, and this removal has the effect of easily converting the weighing and pricing packaging device 1 into a packaging device that does not require weighing and pricing.

Next, FIGS. 5 to 7 show a second embodiment of the present invention, and in this case, the chain conveyor is shorter in length than the chain conveyor 5 of the first embodiment and has a relatively slow product supply speed. The structure, operation, and effects of this embodiment are substantially the same as those of the first embodiment, except that an automatic measuring device 22 and a pricing device 23 are attached to a simplified packaging device 21 in which a device 20 is assembled into the main body of the packaging device.

Next, the effects of the present invention will be explained.

The present invention provides a packaging means for film-wrapping a product placed on a tray while moving the product upward through a push-up supply horizontal structure, and a packaging device that is attached to the product loading position of the packaging means to place the product on the tray. a conveyor for supplying the packaged items to the packaging means in a state where the products are placed on the tray; a measuring device provided at the bottom of the supply conveyor and weighing the products while the products are placed on the tray during the delivery on the supply conveyor; A carry-out means is attached to the product carry-out position of the means to carry out the film-wrapped product; and a carry-out means is attached to the upper part of the carry-out means on the way to carry out the product and prints data such as price on a label based on the weighing result from the weighing means. and a pricing means for pasting the printed label on the film of the packaged product carried out by the carrying out means.
It is in the pricing device.

In other words, in the past, packaging equipment and weighing/pricing equipment were separate units to weigh and price items after packaging was completed. Even if you think about it, weighing and pricing have traditionally been an integrated device, so even if it is a device that combines packaging, weighing, and pricing, it is not possible to use a device that weighs and prices items after packaging is completed. In contrast, the present invention inserts a packaging process between the weighing and pricing processes, which were originally thought to be inseparable, and transforms the entire device into a weighing, packaging, and pricing device. In particular, packaging, weighing, and
We were able to obtain the following effects (1) to (5) that cannot be obtained with pricing devices.

(1) Conventionally, the packaging equipment and the weighing/pricing equipment were separate units, and each work was performed separately. Therefore, each equipment had separate product loading/unloading equipment and temporary holding of products at each loading/unloading position. As a result, product packaging, weighing, and pricing require a considerable amount of equipment installation space and workers, whereas in the case of the present invention, the packaging equipment and weighing/pricing equipment are integrated. Moreover, a weighing means that also serves as the carry-in conveyor is installed at the position of the product carry-in conveyor of the conventional packaging device, and a pricing means is also installed on the product carry-out conveyor of the conventional packaging machine, thereby creating a weighing, packaging, and pricing device. The size of the product is almost the same as that of a single conventional packaging device, and the installation and work space for weighing, packaging, and pricing equipment can be reduced to less than half of the conventional one. Since this is done consistently, the number of workers can be reduced to less than half of the conventional number.

(2) As shown in (1) above, since weighing and pricing are performed at the product loading and unloading sections of conventional packaging equipment, the size of the weighing, packaging, and pricing equipment of the present invention is determined by weighing and pricing.・The size of the entire device including each pricing function can be made quite small, and there is no need for a special loading and unloading section for weighing and pricing, making it suitable for weighing, packaging, and pricing. The assembly man-hours and production costs of the device can be significantly reduced.

(3) Conventionally, the packaging equipment and the weighing/pricing equipment were separate units, so data settings for, for example, product type, number of products per unit package, etc. had to be set separately for each equipment. In contrast, in the case of the present invention, since the weighing, packaging, and pricing devices are integrated, the data setting can be completed with a single operation.

(4) In the case of the present invention, the weighing, packaging, and pricing devices are integrated, and weighing and pricing are performed automatically during the loading and unloading of products into packaging, so weighing and pricing are not included. Since weighing and pricing are performed within the working time required only for packaging the product, the time required for packaging, including weighing and pricing, can be significantly shortened.

(5) When packaging, packaging means that can perform random packaging using a push-up feeding mechanism can be packaged using trays of different sizes as necessary.
Various film widths and lengths can be used.

Therefore, it is natural to package the film to match the width and length of the tray for economic reasons, but
In actual work, the sizes of products and trays often change in units of 5 to 10 pieces, and in order to save time for changing films and converting film lengths, we have created products with larger widths and longer lengths than the trays. It is often used as is.

In this case, the number of grams of film varies by 1gr to 6gr, so in the conventional case of weighing and pricing after packaging is completed, accurate pricing cannot be achieved unless the tare data is changed for each packaging. In contrast, in the case of the present invention, even if the weight of the tare bag differs for each package, since the product is weighed together with a tray of a constant weight before packaging, accurate pricing can always be performed.

In addition, accurate pricing can be achieved by keeping the amount of wraps used constant regardless of the size of the product, that is, by keeping the tare data constant. As a result, packaging defects are more likely to occur when the product is small in volume, and the amount of wrap used is often wasteful, so the amount of wrap used must be varied depending on the bulk of the product.
