Description

  The present invention measures (measures) the weight of an article (inspected object) manufactured by being packaged or cooked in the upstream part of the production line one by one with a weight inspection device installed in the downstream part of the line. Further, the present invention relates to a display device for a weight inspection apparatus that displays the measurement results in a plurality of display forms in an upstream portion of a line and a weight inspection system including the display device.

  Examples of the product production line include a bag package product production line and a baking line. The bag and packaging product production line has a tank for storing contents (liquid or powdered food, cosmetics, medicines, etc.) in the upstream part of the line, and contents supplied from the tank via a flow rate adjusting valve. A bag-making filling and packaging machine or a bag-feeding and filling machine that fills and packs a fixed amount, and an X-ray inspection device, a metal detection device, a weight inspection device, and a sorter at the downstream of the line Yes.

  The weight inspection apparatus includes a separate display device in the upstream portion of the line. The display device is configured to display the measurement results obtained by measuring the weight of bag-packed products (articles) one by one with a weight inspection device in a plurality of display forms.

  The flow rate adjusting valve is a content content setting means. In addition, the line upstream part is separated from the line downstream part, for example, is a semi-clean room, so that an operator cannot freely go in and out with the same work clothes.

  The bag and packaging product production line requires stable and precise control to supply a certain amount of contents from the tank to the packaging machine, but changes depending on the moisture absorption or viscosity of the contents and the liquid level in the tank. Therefore, it is very difficult to control the opening of the flow rate adjustment valve, which is the internal volume setting means.

  If the supply amount is too much, the manufacturer will be damaged. If the supply amount is too low, the content (weight) will be displayed incorrectly. Eliminated.

  The baking line has a conveyor in the upstream part of the line, for example, a tunnel part of several hundred meters, an oven on the inner surface of the tunnel part, and an X-ray inspection apparatus in the downstream part of the line. A metal detection device, a weight inspection device, and a sorter are provided.

  In the bread baking line, weighed bread dough is placed on a conveyor and transported at a sufficiently slow speed, and the bread dough is baked in the tunnel to produce bread (articles). The baking time is controlled by controlling the running speed of the conveyor. Or by adjusting the heating of the oven, and its control is extremely difficult.

  In other words, the conveyor of the baking line is not only a baking adjustment control means but also an internal capacity setting means, and when the running speed of the conveyor is increased (fastened), the baking time is shortened and the evaporation of moisture from the bread is reduced. Therefore, the result of the weight measurement by the weight inspection apparatus becomes heavy.

  In other words, if the bread is too heavy, it means that baking is inadequate, and since the article is a defective product, it is excluded by a sorter so as not to be distributed to consumers.

  Also, if the running speed of the conveyor is reduced (slow), the baking time becomes longer and the evaporation of moisture from the bread increases, so that the result of the weight measurement by the weight inspection device becomes lighter. That is, if the bread weight is too light, the bread will be excessively baked and the display of the content (weight) will be unreasonable, so it will be eliminated by the sorter so as not to damage the consumer.

  Therefore, conventionally, the display device of the weight inspection device is placed separately on the upstream line of the production line away from the weight inspection device, and the weight is measured one by one with the weight inspection device installed in the downstream portion of the line, The measurement result is transmitted to a display device and displayed in a plurality of display forms.

  As an example of such a separate operation control panel, it is constituted by a single separate operation panel provided in common to a plurality of weight sorting devices, and the judgment status by the weight sorting device of each line, etc. A weight selection system that displays on a common operation panel is disclosed (for example, see paragraph number 0032 of Patent Document 1).

  In the baking line, the elapsed time from the baking start time until the bread is conveyed to the weight inspection apparatus is a time lag, and it takes one hour if it is long.

  The display device of the conventional weight inspection device does not control the weight of the previous control even if the display value displayed on the display screen is observed after the time lag elapses after controlling the opening of the flow control valve or the conveyor.
