Abstract

PURPOSE:To enable label pasting on a meeting line of a wrapping paper even if the wrapping paper is thin by a method wherein a label supplying means is provided at a paper meeting line part which is detected by an ultrasonic sensor. CONSTITUTION:A label succession 26 is held in a roll on a holding reel 24 of a label supplier 22, and the label succession 26 consists of a beltlike peeling base paper 28 and a number of labels 30 attached temporarily with intervals on one main surface of the base paper 28. A peeling plate 32 of the label supplier 22 peels the labels 30 from the peeling base paper 28 of the label succession 26. A motor 36 of a winding reel 34 is connected to an output terminal of a control part 20, and the label supplier 22 is driven by a driving signal which is outputted from an output terminal of the control part 20 when a prescribed time period elapses after an ultrasonic sensor 18 detects a meeting line C of a wrapping paper B of a goods A. Further, the label supplier 22 is driven to paste a label 30 on the meeting line C when the meeting line C of the wrapping paper B of the goods A comes to a position of the peeling plate 32.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a label sticking device, and more particularly to a label sticking device that sticks a label to a seam portion of a wrapping paper used to package an article.

(Prior art) This type of conventional labeling device uses a photo sensor or a contact switch to connect the seam of the wrapping paper to the position of the seam of the wrapping paper, because the position of the seam of the wrapping paper changes as the size of the article changes. There is a device that detects the seam and attaches a label to the seam (a problem that the invention aims to solve). However, with this conventional label attaching device, for example, when the wrapping paper is thin, In some cases, it was not possible to detect the pressure at the seam of the wrapping paper using a photo sensor or a contact switch, and it was not possible to attach a label to the seam of the wrapping paper.

Therefore, the main object of the present invention is to provide a label sticking device that can stick a label to the seam portion of wrapping paper even when the wrapping paper is thin.

(Another Means to Solve the Problem) The present invention includes an ultrasonic sensor for detecting the seam of wrapping paper used to package articles, and a label that is supplied to the seam of the wrapping paper detected by the ultrasonic sensor. and a label supply means for applying the label.

(Function) The seam of the wrapping paper is detected by the ultrasonic sensor. Therefore, even if the wrapping paper is thin, the seams of the wrapping paper can be detected.

Then, the label supply means supplies the label to the detected seam portion of the wrapping paper.

Therefore, the label is attached to the seam of the wrapping paper.

(Effects of the Invention) According to the present invention, there is provided a label sticking device that can stick a label to the seam portion of wrapping paper even if the wrapping paper is thin.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

(Embodiment) FIG. 1A is a plan view showing an embodiment of the present invention, and FIG. 1B is a front view thereof.

This labeling device 10 includes a conveyor 12 for conveying articles A. As shown in FIG. This conhair 12 has two rotating shafts 14a and 1.4. b, and these rotating axes 1.4a and 14b have 2
Two healds 16a and 16b are hung at intervals.

An ultrasonic sensor 18 is provided between the two healds 16a and 16b of this conhair 120.

This ultrasonic sensor 18 is for detecting the seam C (see FIG. 2) of the wrapping paper B at the bottom of the article A conveyed by the container 12. The ultrasonic transmitter that transmits ultrasonic waves and its joint C
and an ultrasonic receiver for receiving the ultrasonic waves reflected by the ultrasonic wave, and outputs a detection signal when the seam C is detected.

This ultrasonic sensor 18 is connected to an input end of a control unit 20 that includes, for example, a timer. When a predetermined time set by a timer has elapsed since the detection signal was input to the input terminal of the control section 20, a label supply means 2 (to be described later)
It is configured to output a drive signal for driving 2 from its output end.

The label supply device 22 includes a holding reel 24 provided below the container 12, and a continuous label body 26 is held in a rolled form on this holding reel 24. This label continuous body 26 is made up of a large number of labels 30 temporarily attached at intervals to one main surface of a strip-shaped release mount 28.

This label feeding device 22 includes a peeling plate 32 provided between the two healds 16a and 16b of the container 12. This peeling plate 32 is for sharply folding back the peeling mount 28 of the continuous label body 26, peeling off the label 30 from the peeling mount 28, and feeding the label 30 upward.

A take-up reel 34 is also provided below the connector 712. This take-up reel 34 is
This is for winding up the peelable mount 28 that has been sharply folded back at 32. Therefore, a motor 36 is connected to this take-up reel 34.

The motor 36 of the take-up reel 34 is connected to the output end of the control section 20 described above. Therefore, this label supply device 22 is driven by a drive signal outputted from the output end of the control unit 20 after a predetermined time has elapsed since the ultrasonic sensor 18 detected the seam C of the wrapping paper B of the article A. .

In addition, the predetermined time in this case can be set to be the same as the time during which the article A is conveyed from the ultrasonic direction sensor 18 part to the peeling plate 32 part of the label supply device 22 by the conhair 12 by adjusting the timer of the control unit 20. and the time is set. Therefore, this label supply device 22 is driven when the seam C of the wrapping paper B to the article is located at the peeling plate 32 portion.

Therefore, in this labeling device 10, for example,
Seam C of wrapping paper B to the article whose bottom surface is shown in Figure 2
A label 30 can be attached to the portion as shown in No. 30.

Furthermore, in this labeling device 10, wrapping paper B is attached to the article.
Since the seam C is detected by the ultrasonic sensor 18, the seam C can be detected even if the wrapping paper B is thin.

Therefore, even if the wrapping paper B is thin, the label 30 can be attached to the seam C portion.
