Description

[Detailed Description of the Invention] This invention relates to a combination scale used to pack easily damaged articles to be weighed into bags or the like at approximately predetermined weights.

2. Description of the Related Art Generally, articles to be weighed are sometimes packed into bags or the like in predetermined weights and sold. When making bags in this way, it is desirable to do all the work automatically to increase work efficiency, but if the items to be weighed are soft or easily lose their shape, it is important to avoid damaging them. It was both easy and difficult to come. Therefore, conventionally, a scale such as a top-pan automatic scale was used, and the weight of the articles to be weighed was adjusted by rearranging them in various ways to reach a predetermined weight, and then the articles were manually packed into bags or the like. Therefore, it was extremely inefficient and could not be improved without a lot of manpower.

The purpose of this invention is to provide a combination scale that can efficiently pack easily damaged items into bags or the like with a small amount of manual labor.

This invention will be explained below based on one embodiment shown in the drawings. In Fig. 1, 1 to 10 are measuring instruments,
The weighing pans are arranged in a line along the length of the box-shaped envelope 12 in the center thereof, and the weighing pans
are provided so as to protrude upward from the upper surface of each. On the upper surface of this envelope 12, these measuring instruments 1 to 10 are placed on both sides of the measuring instruments 1 to 10.
Selection result indicator lights 13 to 22 and carry-in weighing instrument indicator lights 23 to 32 are provided so as to correspond to each other.

As shown in FIG. 2, a support stand 33 is provided to protrude outward from the side surface of the envelope 12 on which the selection result indicator lights 13 to 22 are provided, and a support base 33 is provided on the side surface on which the selection result indicator lights 13 to 22 are provided. An unloading belt conveyor 34 is disposed parallel to the length direction of 12.

Reference numeral 36 denotes a panel, in which a control section 37 composed of, for example, a microcomputer is housed. This control unit 37 electrically combines various weighing signals sent from the weighing instruments 1 to 10, selects a combination of the weighing instruments 1 to 10 that provides a predetermined weight or a weight close to it, and displays the selection result. When the lights 13 to 22 corresponding to the weighing instruments included in the selected combination are turned on and the articles to be weighed are carried out from these weighing instruments, the carried-in weighing instrument indicator lights 23 to 32 are turned on for weighing carried out. It lights up the one that corresponds to the container.

In the combination scale configured in this way, the articles 35 to be weighed are now placed on the weighing pans of each of the scales 1 to 10, and the conveyor belt 34 for carrying out is running in the direction shown by the arrow in FIG. Suppose there is.
In this state, the control section 37 performs various combinations, and when, for example, the measuring instruments 1, 4, 6, and 8 are selected, the selection result indicator lights 13, 16, 18, and 20 light up.
In accordance with this instruction, a carry-out person 38 standing on the side of the carry-out belt conveyor 34 as shown in FIG. The loaded articles 35 to be weighed are conveyed by an unloading belt conveyor 34 and packed into a bag or the like at a predetermined position.

In addition, the article to be measured 3 from the weighing instruments 1, 4, 6, and 8
5 is discharged, the control unit 37 turns on the carry-in weighing instrument indicator lights 23, 26, 28, and 30. In accordance with this instruction, as shown in FIG. will be brought in. Thereafter, the articles 35 to be weighed are packed into bags or the like at approximately constant weights in the same manner.

In this combination scale, the selection result display lights 13 to 22 are provided to correspond to the measuring instruments 1 to 10 arranged in a row, respectively, and the belt conveyor 34 for carrying out is provided in parallel to these measuring instruments 1 to 10.
According to the lighting of the selection result indicator lights 13 to 22, the article to be weighed 35 is carried out from the selected one of the weighing instruments 1 to 10 onto the carrying out belt conveyor 34,
By simply carrying out the simple task of loading a new article to be weighed 35 into an empty weighing instrument, two people can efficiently pack the easily damaged articles to be weighed 35 into bags or the like at approximately a predetermined weight. can.

In the above embodiment, the carry-in weighing instrument indicator lights 23 to 32 are set to light up when the article to be weighed 35 is carried out from the weighing scales 1 to 10, but they are set to light up at the same time as the selection result indicator lights 13 to 22. You can also do this. In some cases, the loading scale indicator light 2
3 is unnecessary. In addition, a belt conveyor 34 for carrying out
However, any unloading device may be used as long as it can unload the articles to be weighed without damaging them.
