Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a weighing label issuing device. [Prior Art] Conventional weighing label issuing devices generally install a printer near the label output port, feed the tape with labels pasted at regular intervals, pass the printing position of the printer, and detect the label. The printer detects the label one label behind the one to be printed, stops the tape feed, sets the front label at the printer's printing position, and the printer records the weight, unit price, price, and date on the front label. etc. were printed. [Problem to be Solved by the Invention] However, in the above-mentioned conventional weighing label issuing device, the tape feed is not stopped unless the label detector detects the rear label. If one of the labels attached to the tape is missing, for example, the label attached just before the missing part will be detected by the label detector at the rear even if the label attached just before the missing label reaches the printing position of the printer. Since the label was not detected, the tape feed was not stopped, resulting in the issue of unprinted labels. Moreover, when the label detector detects a label located immediately after the part where the label is missing, the tape feed stops and the printing operation is performed, but at this time, the printer's printing position is located at the part where the label is missing. As a result, the printer would run dry and the lifespan of the printer's hammer, dot head, etc. would be shortened. Therefore, the present invention eliminates the risk of issuing an unprinted label when a part of the label that is supposed to be attached to the tape at regular intervals is missing, and also extends the life of the printer by preventing dry printing of the printer. The purpose of the present invention is to provide a weighing label issuing device capable of weighing. [Means for Solving the Problems] As shown in FIG. 10, the weighing label issuing device of the present invention includes calculation means B that calculates a price from weight data taken in from a weighing section A and input unit price data. , a printer D that prints the weight, unit price, price, etc. on the label C, a label feed mechanism E that feeds the label C to the printing position of the printer D, and a rear label C ₁ that is fed by the label feed mechanism E. A label detector F detects the end and sets the front label _C2 at the printing position of the printer D, and this label detector F detects the front label C2.
a determining means G for determining the presence or absence of a detection output from the label detector F with _C2 set at the printing position of the printer D; and when this determining means G determines that a label is detected, it permits the printing operation of the printer D; The apparatus also includes a print control means H which prohibits the printing operation of the printer D when it is determined that no label is detected. [Operation] With a weighing label issuing device that employs such means, when the label detector detects the end of the rear label fed by the label feed mechanism, the front label is set at the printing position of the printer. The label feed is controlled to stop so that the At this time, there is a slight deviation before the label completely stops, and in anticipation of this deviation, the front label is set at the printing position of the printer. When a label further behind the rear label is detected by the label detector due to this label shift, it is determined that no label is missing, and printing operation on the front label is permitted. On the other hand, if the label detector does not detect a label, it is determined that a label further behind the rear label is missing, and the printing operation on the front label is prohibited. Therefore, unprinted labels are not issued, and blank printing of the printer is also prevented. [Example] Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing the external appearance, where 1 is a weighing section and 2 is the main body of the device. A display and operation section 3 and a label outlet 4 are provided on the front surface of the apparatus main body 2.

〔Effect of the invention〕

As described in detail above, according to the present invention, a label detector is used that detects the rear label and sets the front label at the printing position of the printer, and when the label detector stops detecting the label, the printer Since the printing operation of the printer is prohibited, if a part of the label that is supposed to be attached to the tape at regular intervals is missing, there is no chance of printing an unprinted label, and it also prevents the printer from printing blankly. It is possible to provide a weighing label issuing device with a simple configuration that can prevent the above problems and extend the life of the printer.
