JPS592505Y2 - Weighing device - Google Patents

Description

[Detailed description of the device] This device is designed to measure the weight of each unit while transporting the weight to be weighed, which has been packaged and packaged in a substantially constant shape and separated into units, and a label indicating the weight of the unit. This allows for automatic issuance of .

Generally, most of this type of work is done manually, and although it requires a lot of man-hours, there are many errors in the work, and improvements are desired.

In view of these points, the present invention aims to improve work efficiency and prevent erroneous work by automating weighing, calculation, label display, etc.

That is, this invention includes a supply conveyor for transporting the weight objects separated into units, a weighing conveyor that receives the weight objects, weighs them, and then transfers and discharges them.
A device that sets the tare of the heavy object to be weighed, a device that calculates the weight based on signals from the tare setting device and the weighing conveyor, and a device that displays the weight of the heavy object on the label when the calculation of the weight calculation device is completed. Separated from the printing device, each conveyor is provided with a device that detects a weight to be weighed on its way and stops driving the conveyor, and is driven when the printing device finishes printing.

To explain this with reference to the attached drawings, in the figure, 1 is a heavy object detection device consisting of a phototube that detects the presence of a heavy object 12 near its end and stops the electric motor 2 that is its drive source. A supply conveyor 4 is equipped with a device 3, and 4 is a short weighing conveyor equipped with a heavy object detection device 7 on its way, similar to the supply conveyor 1, and is installed on a scale 5 to weigh a heavy object 12 to be weighed. ,
The numeric keypad 10 converts the value into an electrical signal and serves as a storage device.
It is now possible to put it into the

Both conveyors 8 and 8 are made to run in the direction of the arrow, and the running speed of the weighing conveyor 4 is set to be faster than that of the other conveyors 1 and 8.

9 is a device for setting the tare weight of the heavy object 12 to be weighed, and a signal from this device is input to the numeric keypad 10 and sent to the weighing conveyor 4.
Due to the operation of the detection device 7 at
It will be put into 1.

This converter bar 11 has a mechanism that calculates the net weight of the weight to be weighed 12 based on signals from the numeric keypad 10, and a mechanism that converts these signal values into numbers and prints them at predetermined positions on the label. Furthermore, a mechanism is provided for operating electric motors 2 and 6 to drive conveyors 1 and 4 at the same time as printed labels are issued.

In such a configuration, when a tare value is input to the device 9, -
When the conveyors 1, 4, and 8 are driven to supply the heavy object 12 to be weighed, the heavy object 12 to be weighed blocks the detection device 3, and the conveyor 1 is stopped by the operation of the device 3, and the heavy object 12 to be weighed is stopped by the operation of the device 3. stops moving.

At this time, if there is a heavy object 12 on the weighing conveyor 4, the weighing conveyor 4 measures the weight while moving the heavy object 12, and transmits the signal to the numeric keypad 10.

Then, the conveyor 4 stops when the heavy object 12 to be weighed blocks the detection device 7.

At this time, the numeric keypad 10 is activated by the operation of the detection device 7, and transmits the stored tare weight signal and total weight signal of the heavy object 12 to be weighed to the converter bar 11.
The net weight of the product is calculated, and a label with the gross weight, tare weight, and net weight printed on it is issued.

As the labels are issued, the electric motors 2 and 6 are activated and the conveyors 1 and 4 are driven, so the weighed items 12 are quickly sent from the conveyors 4 to 8, and the items 12 waiting to be weighed are sent from the conveyor 1 to the conveyor 1. 4, and weighing and labeling are performed in the same manner as above by the operation of each device.

In this way, the weighing operation of the heavy objects 12 to be weighed that are sent in one after another is performed, and the printed label issued from the converter bar 11 is printed on the surface of the heavy object 12 discharged onto the conveyor 8 by the conveyor 8. will be attached sequentially.

As is clear from the above explanation, this invention is designed to link a conveyor that repeatedly stops and stops, a calculation device, and a label printing device. According to this system, by setting a tare, weighing, Calculations and label issuance can be performed continuously and automatically, which not only further improves work efficiency but also prevents erroneous work.

Moreover, each conveyor can detect and stop the heavy objects to be weighed, so there are advantages such as reliable weighing of each heavy object.
Its industrial value is extremely large.

In the previous example, a computing device and a printing device were used in one unit, but this could also be a separate device, and a device equipped with other work means could be used to perform other tasks at the same time. For example, it is okay to create a daily report.
