Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for feeding labels to a labeling machine for automatically applying labels to containers such as bottles.

In the case of a conventional label pasting machine, sheets of labels cut to predetermined dimensions are stacked and stored in a label storage frame, and the label is pushed onto a tab provided in the label storage frame; Using the adhesive force of glue applied to a glue plate from the outside or the suction force of a vacuum head, one label was taken out, transferred to a container, and affixed. However, with this method of using single-fed labels, supply errors often occur, such as stored labels coming off the hook and falling off, multiple labels being taken out at the same time, or labels not being taken out at all. It was occurring in Especially if two labels are taken, the front label without glue,
That is, a situation occurs in which the label on which the date, expiration date, etc. are printed falls off after the label is removed, and a serious problem arises in that the manufacturing date, etc., of medicines and the like are not displayed. In addition, in pharmaceutical factories and cosmetic manufacturing factories that handle a wide variety of drugs using the same labeling machine, there is a risk that serious accidents may occur due to mixed labeling of different types of labels.

In order to solve this problem, a roll labeler is provided that rolls up a strip of paper on which labels are continuously printed, pulls it out, cuts it one by one, and attaches it to containers, and is especially used for pharmaceutical containers. Furthermore, compared to sheet-fed labels, they do not require label replenishment over a long period of time, so they have come to be used in various industries.

This conventional roll labeler is designed to cut a strip of paper on which labels are continuously printed and cut it into unit labels at the label supply position, but errors in the cutting position accumulate due to expansion and contraction of the paper. In order to avoid cutting the paper at the center of the label, it is necessary to print an alignment mark on the label and correct the cutting position while detecting this mark with a sensor. However, this cutting position correction device often malfunctions, and the cutting cutter not only needs to be resharpened every time a certain amount of cut is made, but also foreign objects can get stuck in the cutter, causing the machine to stop. The problem was that there were many accidents.

This invention was made in order to solve the problems of the conventional means described above. Labels that have been separated into unit labels in advance are connected in a band shape by a transport band, and the labels are sequentially pulled out by pulling out the transport band. , the unit labels are separated from the transport band at the label supply position and supplied to the labeling machine.

Next, the method and apparatus of the present invention will be explained based on the illustrated embodiments.

It is.

Regular label supply device 30 and spare label supply device 30
Since the basic configuration is the same as that of the regular label supply device 30, only the regular label supply device 30 will be described below.

FIG. 7 is a perspective view showing a label supply part of the apparatus of the present invention using the label paper 4a shown in FIG. When the label seat 15 of the transfer drum 13 enters the label supply position A, it rotates only one revolution. Although not shown in the figure, the rotational drive mechanism of the supply roller 40 is composed of, for example, an electric motor with a Geneva gear mechanism interposed therebetween, and its rotation timing is determined by the protrusion 41 installed on the transfer drum 13.
. . 41 is detected by the photoelectric sensor 42.

The supply roller 40 has an eccentric cylinder 39 connected to the transfer drum 13.
When the label seat 15 of the transport drum 13 enters the label supply position A, it rotates once and transfers the leading edge of the unit label 2 of the label paper 4a to the transport band i. , 1 is pressed against the tip of the label seat 15 that has entered the label seat 15 after being separated from the label seat 15. Then, the leading edge of the unit label 2a is attracted to the label seat 15 by the small hole 16, and as the transfer drum 13 rotates, the unit label 2a is separated from the transfer band 1.1 at the perforation 5 and is attached to the transfer drum 13. It is delivered. At this time, the winding roll 35 shown in FIG. 6 rotates in accordance with the circumferential speed of the transfer drum 13 and winds up the separated transfer bands 1, 1, and by the winding operation of the transfer bands 1, 1. The unit label 2 to be supplied next is delivered to the label supply position A.

FIG. 10 shows the label delivery member 34 when using the label sheets 4b to 4d shown in FIGS.
is the supply low. The supply roller 46 has a large diameter roller 47 at its center, and receiving blades 48 and 49 are formed at the upper and lower ends of the large diameter roller 47 to work together with the slitter 43 and 44 to transfer the unit label 2 to the transport bands 1 and 1. The structure is such that it can be separated from the That is, when the photoelectric sensor 42 detects that the label seat 15 enters the label supply position A, the slitter 43 .
44 and supply roller 46 rotate to separate the unit label 2 from the transport bands 1 and 1 and press it against the label seat 15, and the transport drum 13 receives the unit label 2 by the negative pressure acting on the small hole 16. It is. At this time, as described above, the winding drum 35 in FIG. The rotation will be stopped while the is being sent.

As mentioned above, when the label paper in the label roll 31 runs out, it becomes necessary to connect the rear end of the label paper to the label paper in the label roll 32.The end of the label paper is shown in FIG. If the transfer band 1 is shaped so that its end portion protrudes from the unit label 2, the leading edge of the new label paper 4n can be attached to the old label by overlapping the protruding portions 1a of the transfer band and gluing them together. It can be connected to the rear end of the bell paper 4.

Since conventional label paper did not have such a transport band 1, the labels overlapped at the joints of the label paper, resulting in an extremely unsightly appearance.However, the label paper 4a...4e of the present invention By using this, it is possible to avoid overlapping of unit labels at the connecting part of the label paper.

As can be understood from the explanation of the above embodiments, by using the label feeding method and device of the present invention, it is possible to avoid cutting errors caused by expansion and contraction of the label paper, and it is possible to avoid the cutting position detection mark on the label paper and its detection. Since there is no need to provide a cutting device, the problems with conventional roll labelers are solved, and there is no risk of supply mistakes such as taking two labels, and labels can be supplied extremely stably.
