Description

[Detailed description of the invention] The present invention relates to a measurement value labeling device for packaging articles and affixing a printed label created based on at least the measurement value of the article to the packaged article. The aim is to improve performance and reduce work space.

Fig. 1 shows a line-up of a conventional weighing and pricing device, in which a packaging machine 1, a weighing device 2, and a pricing device 3 are arranged from the upper side to the lower side of the article conveyance path, and after the packaging machine 1 completes packaging, The articles are conveyed by the belt conveyor 4 to the weighing position of the weighing device 2. For example, the conveyance of the articles is temporarily stopped at the weighing position, and the belt conveyor 4 detects that the weighed value output from the weighing device 2 is balanced. 5 to the pricing position of the pricing device 3, the pricing device 3 prints predetermined items on the label based on the weight value obtained by the weighing device 2, and the label is conveyed to the pricing position of the pricing device 3. It is configured to be affixed to items that have arrived. Here, the packaging operation of the packaging machine 1 is performed when an article is placed on the belt conveyor 6 based on the output of the article detection device 7 that detects that the article is placed on the article purchasing belt conveyor 6 of the packaging machine 1. It is configured to automatically transport and start. Therefore, with conventional weight value marking devices,
It is necessary to place the products on the belt conveyor 6 in a state where the products are completely arranged on the tray, and it is necessary to provide a work space in advance to arrange the products on the tray. It is also conceivable to provide a timer device on the belt conveyor 6 to carry out the plating and delay the output of the article detection device 7 for a predetermined period of time. It is necessary to set the time for a long time, and the time from the completion of the plating work to the start of conveyance reduces work efficiency, and this cannot be a solution to the above problem.

On the other hand, the weighing device of the present invention can avoid the above-mentioned problems by effectively utilizing the weighing device 2 arranged in the article conveyance path. An explanation will be given based on an embodiment shown in FIGS. 2 to 5.

Figure 2 shows the line-up of the weighing device,
A weighing device 2, a packaging machine 1, and a pricing device 3 are arranged from the upper side to the lower side in the article conveyance direction, and the articles are distributed from the weighing device 2 to the packaging machine 1 and from the packaging machine 1 to the pricing device 3.
are conveyed by belt conveyors 8 and 9, respectively. However, the conveyance operation of the belt conveyor 8 is controlled by the balance detection signal A of the weighing device 2, and the pricing device 3 receives weight information from the weighing device 2.
It is configured so that a label printed based on Dg is affixed to the product after packaging is completed.

FIG. 3 shows the configuration of the belt conveyor 8 whose conveying operation is controlled by the balance detection signal A, in which 10 is the weighing object holder of the weighing device 2, and 11 is the weighing device main body, which acts on the cradle 10. a load cell 12 as a load converter that detects a load value;
Amplifier 13 and load cell 1 via amplifier 13
An analog/digital converter 14 that converts two outputs into digital, a motion detector 15 that monitors weighing information Dg output from the analog/digital converter 14 to detect a balance state, and an overweight detection device 16 (described later), etc. Built-in. The belt conveyor 8 is operated continuously, for example, and one end on the upper side of the conveyance path is supported by an air cylinder device 17 so as to be movable up and down.

FIG. 4 shows the stem 18 of the air cylinder device 17.
3 shows a cross section taken along the line X-X in the state shown in FIG. When the stem 18 is raised, the forward belt 20 protrudes from the upper surface of the tray 10 and is configured to transport, for example, a tray 22 as an article placed on the upper surface to the packaging machine 1.

FIG. 5 shows an electrical system diagram, and 16 is the overscale detection section, which monitors the weighing information Dg, detects that it exceeds a predetermined weighing value, and outputs an overscale signal B. 23 is a switch for turning off the output of the balance detection signal (hereinafter referred to as balance signal) A of the output of the motion detector 15;
4 is an AND gate which outputs the logical product of the overscale signal B and the balance signal A via the switch 23. Reference numeral 25 denotes an air cylinder driving section of the air cylinder device 17, which is controlled by the output of the AND gate 24 to drive the stem 18 when the measured weight is less than a predetermined weight and the balance signal A is outputted via the switch 23. is configured to maintain the rising state for a predetermined period of time. 26 is the FIFo register,
The writing of the weighing signal Dg is instructed by the same AND gate 24 output every time a stem raising instruction is issued to the air cylinder device 17, and the written content is read out every time a readout signal R, which will be described later, is generated. There is. 27, the goods being conveyed to the pricing device 3 via the packaging machine 1 are conveyed to the belt conveyor 9.
A label is attached to the pricing device 3 using a position detection device that detects passage of a predetermined position.

With this configuration, the switch 23 first outputs the balanced signal A from the motion detector 15.
If we pay attention to the case where the handler places the tray 22 on the pedestal 10 and performs the work of plating the products in the make state in which the information is input to the AND gate 24, and in the standby state in which the stem 18 is lowered, Since the handler's hand is touching the transported object until the work is completed, the balance signal A is not input to the AND gate 24 via the switch 23, and even if the overscale detection signal B is Even in the state where no output is produced, no stem raising instruction is given to the air cylinder drive section 25, and the wrapping operation is not started during the plating operation. When the plating work is completed, unless the overscale detection signal B is generated, when the balance signal A is generated, the stem 18 is raised and the packaging operation is started, and the articles on the tray 10 are immediately transported to the packaging machine 1. be done. Along with this carry-in operation, the FIFo register 26 receives a write instruction and stores weight information Dg at that time. After the packaging is completed, the article is conveyed by the belt conveyor 9 toward the pricing device 3. When the position detection device 27 detects the article, it instructs the pricing device 3 to print a label, and the pricing device 3 transfers the label to the FIFo register 26. Output the readout signal R to the weighing information Dg
is read out, the label is printed, and when the article arrives at the label affixing position, the pricing device 3 affixes the printed label to the article.

Therefore, it is possible to carry out the work of plating the articles on the weighing device 2, so there is no need to provide any other space for the plating work. Further, when the plating work is completed, the balance signal A is generated, and the packaging operation can be started automatically and without delay, so that there is no reduction in work efficiency. In addition, packaging machine 1
By setting the setting value of the overscale detection unit according to the capacity of the packaging machine 1, it is possible to prevent articles exceeding the packaging capacity from being carried into the packaging machine 1. Failures due to clogging of articles can be prevented, and the structure can be simplified and the reliability of the device can be increased.

In addition, the switch 23 and a weight display section that displays the weighing information Dg as weight or a display section that displays the result of processing the weighed value using a predetermined value (such as the price of the object to be weighed obtained by processing the weighed value as a unit price) Of these, by arranging at least the switch 23 near the weighing device 2 and configuring it so that it can be operated by the person doing the serving work, a separate weighing device can be prepared by using the weight display section, etc. At least it can be arranged in fixed quantities.

In the above embodiment, the pricing device 3 is configured to accept the weighing information Dg from the weighing device 2 via the FIFo register 26, but this is because a plurality of articles are on the conveyance path between the weighing device 2 and the pricing device 3. This is only necessary in the case of processing speeds or the intervals between the articles introduced into the packaging machine 1, such as those that exist.

In addition, in the above embodiment, the articles are conveyed from the weighing device 2 to the packaging machine 1 via the belt conveyor 8, and the conveyance is turned on and off by moving the upper end of the belt conveyor 8 up and down in the conveying direction. However, the same effect can be obtained even if the rotation of the conveyor belt that performs conveyance is controlled by turning on and off.

As explained above, according to the present invention, the weighing device, the packaging machine, and the pricing device are sequentially arranged toward the downstream side in the article conveyance direction, and the packaging operation is started upon detection of the balance detection signal of the weighing device. Since the pricing device is configured to print a label based on the weighed value of the weighing device, it is possible to carry out work such as plating products on the weighing object holder of the weighing device. It is possible to reduce the work space because no separate space is required for plating, and since packaging can be done without delay after plating is completed, there is no reduction in work efficiency and it is expected to improve operability. It is.
