Since the conveyor, which also served as a weighing pan, was required to function only as a conveyance means, it was kept in constant operation. However, if the carry-in conveyor that carries products into the above-mentioned device and the conveyor that also serves as a weighing pan are arranged perpendicularly to each other, and the conveyor that also serves as a weighing pan is kept in continuous operation, the transfer of products may be difficult. The problem is that it is difficult to transport the materials reliably.

In order to solve the problems of the prior art described above, the present invention aims to reduce the size of the device and improve the positional accuracy of label pasting, and also provides a device that functions reliably as a conveyance device even when no labels are required. With the goal.

The device of the present invention that achieves this purpose is a weighing and pricing device in which a carry-in conveyor for carrying in products is connected to a weighing conveyor equipped with a weighing device, and a label printer is disposed above or below this weighing conveyor. The conveyor is arranged so that its conveyance direction is perpendicular to the carry-in direction of the carry-in conveyor, a detector is provided to detect when a product is carried on the weighing conveyor, and whether or not the label printer issues a label is selected. Provide a means of selection,
If label printing is selected by the selection means, the weight data is printed and issued by the label printer using the detection signal of the detector and the weighing signal of the scale, and the label printer prints and issues the weight data in synchronization with the pasting operation of the label printer. The weighing conveyor is driven to carry out the product, and when the selection means selects not to issue a label, the control means drives the weighing conveyor using the detection signal from the detector and the weighing signal from the scale to carry out the product. It is characterized by having been provided.

The above-mentioned weighing conveyor may be either a roller conveyor or a belt conveyor, and the conveyor may be horizontal or inclined depending on the shape of the carry-in path.

In addition, the label pasting method using a label printer is such that the printer is installed above the weighing conveyor and the label is pasted on the top of the product.The bottom pasting method is where the printer is installed below the weighing conveyor and the label is pasted on the bottom of the product. You are free to use any method of pasting.
