Description

[0001]
[Industrial application fields]
The present invention relates to a label printing / applying device for attaching a printed label such as a quality display or a date quality display on an article such as a chicken egg or fruit.
[0002]
[Prior art]
In the egg laying date display, a sticky label printed with a date is attached to each so-called packed egg. After packing the eggs, they are conveyed on the conveyor in the longitudinal direction, and the printing sticking device performs printing on the label in synchronization with the sticking and feeding.
[0003]
[Problems to be solved by the invention]
The present invention is intended to increase the speed of the pasting portion without increasing the speed of the printing means.
[0004]
In the present invention, it is possible to provide printing means at intervals different from the intervals between the affixing means with respect to a plurality of rows of label affixing means installed with a certain width, such as hen eggs conveyed in 2 rows An object of the present invention is to provide a label printing / applying device.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, in the apparatus of the present invention, a printing feed means for printing on a label and a sticking feed means for sticking the label to an article such as an egg are provided separately. The release paper with the printed label in between is held in a relaxed state, that is, a sagging state.
[0006]
Also, the printing means and the label running means for printing so that the number of printed labels existing between the two running means is always more than a certain number by counting the number of labels attached to the articles such as eggs. A control device for controlling (print feeding means) is provided.
[0007]
Further, after printing on a plurality of rows of labels that run in parallel with the width of the release paper, a regulating member for changing the running center of the printed release paper to the transport row width of the article to be attached is provided between the two running means. It is effective when it is provided.
[0008]
The printing means preferably uses a print head portion of a dot printer or an ink jet printer, and is preferably operated in synchronism with the print feed means of the label which is the printing medium. The drive source of the print feed means is a pulse motor or the like. Use a servo motor.
[0009]
In addition, a good result can be obtained when a pulse motor or a servo motor is used as the drive source of the sticking and feeding means to perform frequent intermittent operation, sudden start and stop according to arrival of the article to be stuck.
[0010]
[Action]
The label printing / applying apparatus configured as described above starts to use after storing a predetermined number of printed labels in the relaxed portion (5) in the initial state.
[0011]
In the above apparatus, the pasting and feeding means operates in response to the arrival of the article to be pasted and feeds the printed labels one by one to stick the article to be pasted. The drive of the sticking and feeding means performs an intermittent operation.
[0012]
When the counting device for the number of stickers prepared in the control device counts out a certain number of labels, the control device performs continuous printing on a predetermined number of labels by operating the print feeding means and the printing means installed upstream of the label tape. The labels present in the relaxed portion (5) are replenished, and a certain number of labels are always stocked.
[0013]
Here, the operation of the printing and feeding device is controlled so as to continuously print a plurality of labels, and the driving of the sticking and feeding is controlled so as to stop every time one feeding operation is performed per article to be stuck. . As a result, it is possible to run the printing feed at a speed slower than the sticking feed running speed.
[0014]
By controlling the printing means to continuously operate so that characters, symbols, etc. are printed on a fixed number of labels, the printed label is sent out at a higher speed without being limited by the limit speed of the printing means. Also, the number of labels consumed in the relaxed portion (5) is replenished without delay by counting the number of times of the sticking and feeding operation.
【Example】
[0015]
The embodiment will be described with reference to the drawings. In FIG. 1, the arrival of the ten-packed chicken egg pack 10 conveyed by the conveyer (9) to the label attaching portion is detected by the egg detector (23).
[0016]
The control device (4) receives the detection signal from the egg detector (23) and drives the sticking and feeding means (2) to send out one label. The one label is controlled to be sent out from the affixing part (11) with the adhesive surface down, at a speed approximately equal to the transport speed of the transport conveyor (9) and at the timing when the top surface of the egg reaches the label. The sticky side of the label that has been sent out is pasted on the top of the egg.
[0017]
When the label detector (22) detects one label feed, the sticking feeding means (2) stops the feeding operation and waits for the next egg detection signal to be input from the egg detector (23). The control device starts sending out one label and simultaneously adds 1 to the pasting number counter prepared in the control device.
[0018]
At the same time that the label application starts to apply the fifth label, the control device replenishes the label stocked in the loosening part (5) with the print means (3) and the print feed means (1). Is operated to print predetermined character symbols on five labels in succession.
[0019]
The release paper winding means (8) is always driven to wind the release paper with a constant tension, and the release paper after the label is peeled off at the affixing section (11) is taken up.
[0020]
In this embodiment, two sets of printing means (3) are arranged in close contact with each other with a width of about 20 mm for printing two rows of label tapes, and the relaxed portion (in which the tape after printing is in a relaxed state) In 5), a regulation guide (12) is provided to widen the two rows of tapes having the center distance of 20 mm to 47 mm which is the top width of the two rows of eggs. Each label expanded to the top width of the egg by the regulation guide (12) is configured to pass through the resistor (6) pressed with felt to obtain a certain tension at the affixing part (11). .
[0021]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
[0022]
The label affixing operation needs to send out the label at a speed approximate to the conveyance speed of the article corresponding to the arrival of the article to be affixed. Further, since the labels are attached to individual articles one by one, the feeding is an intermittent operation.
[0023]
The apparatus of the present invention is configured so that a predetermined number of printed labels are always stocked in the relaxed portion, and the stocked printed labels are used for affixing and feeding requiring high speed operation. It is supposed to be. The label running speed during printing, which is directly influenced by the performance of the printing apparatus, is configured to be driven by a printing drive means prepared separately.
[0024]
In the present invention, the label running speed at the time of printing is controlled so as to continuously print a predetermined number of sheets. Therefore, the number of labels attached and fed intermittently within a predetermined number of continuous printing times does not exceed the number of printed sheets. The speed can be increased within the range, and it is possible to cope with the high-speed conveyance of the article to be pasted.
[0025]
In addition, the amount of stock in the slack section (stock section) is measured by subtracting the number of labels from the number of printed labels, so there is no need to prepare a special detection device, and the tape is virtually tension free during this time. This makes it possible to change the tape running interval in the stock section.
[0026]
The tape running interval change in the stock section makes it easy to change the attaching interval to the article to be attached to be transported in a plurality of rows, and to the article to be attached that has a large attaching interval and is conveyed in a plurality of rows. Labeling is realized by one apparatus of the present invention.
[0027]
Further, by reducing the label in the stock portion by the subtraction calculation, it becomes possible to detect the consumption of a predetermined number of sheets simultaneously with the start of the pasting and feeding of a predetermined number of labels. Replenishment can be started immediately, and it has become possible to cope with an increase in the conveying speed of articles to be pasted.
