Description

[Detailed description of the invention] The present invention conveys the label peeled from the mount by the label peeling plate of the label printing machine into the label holding recess formed in the bottom plate of the label sticking device main body, The present invention relates to a structure of a label holding part in a label sticking device, in which a fan sucks a label that has entered the recess, holds it in the recess, and sticks the held label to a predetermined location on a product.

In a label sticking device having the above-mentioned function, when the label is conveyed toward the holding recess, the inertial force due to the conveyance is too large than the suction force of the fan, and the label does not enter the holding recess. Otherwise, there is a risk that the object may pass under the holding recess.

Therefore, the present invention provides a mechanism for a label holding part that solves these problems.

An embodiment of the present invention will be described below with reference to the drawings.

1 is a label issuing machine, and 2 is a label sticking device attached to the front of the issuing machine 1, which extends horizontally from the issuing machine 1.

3 is an adhesive box, and inside the box 3 is a partition plate 4.
It is divided into large room 5 and small room 6.

7 is a label holding port formed in the bottom plate 3a of the box 3 below the small chamber 6; 8 is a fan disposed in the large room 5; the air outlet 8a of the fan 8 is connected to the It penetrates through the partition plate 4 and is located above the label holding opening 7.

Reference numeral 10 denotes a pair of gates for opening and closing the air blowing path connecting the holding port 7 and the air blowing port 8a, and when the gate 10 is in the horizontal state shown in FIG.
The interior is divided into an upper chamber 6a and a lower chamber 6b, and the air blowing path is closed.

Although not shown, the upper chamber 6a communicates with the outside air via a communication hole.

12 is a communication hole formed in the partition plate 4 that communicates the upper chamber 6b with the large room 5; 16 is a disk fixed to the rotating shaft 9 of the gate 10; and 17 is a lower end that is the outer peripheral edge of the disk 16; A connecting rod connected with a pin in the vicinity, the connecting rod 1
7 is pulled upward from the state shown in FIG. 1 by a driving means such as a solenoid, the gate I.10 rotates 90 degrees and stands upright, opening the air blowing path and allowing air to flow from the blowing port 8a of the fan 8. The blown air reaches the label holding port 7.

65 is four notch grooves formed in the box bottom plate 3a from the label holding port 7 toward the label peeling plate 45,
It communicates with the lower chamber 6b.

Reference numeral 21 denotes a label conveying device provided under the box 3, which includes a guide plate 22 fixed to the bottom surface of the box 3 and guiding the label 25 to the label holding port 7, and a guide plate 22 provided close to the bottom surface of the guide plate 22. The belt conveyor 23 has a pair of mutually parallel frames 35 fixed to the lower surface of the box 3, and a label holding opening 7 that passes the end of the notch groove 65 on the side of the label peeling plate. A small diameter roller 36 whose both ends are rotatably supported by the frame 35 in the vicinity, and a spindle 37 whose both ends are rotatably supported by the frame 35 in the vicinity of the label issuing machine 1.
, a large-diameter roller 38 having four annular grooves 38 a fixed on the support shaft 37 , and a telescopic roller 4 extending between each annular groove 38 a of the large-diameter roller 38 and the small-diameter roller 36 . A drive that rotates the spindle 37 and large diameter roller 38 at high speed (approximately 100 m/min) through a rubber belt 39 and a pulley 40, a belt 41, and a pulley 42, which is installed on the bottom plate 3a of the box 3. It has a motor 43 and a presser roller 44 whose both ends are rotatably supported by the frame 35 and which approaches the upper end of the large diameter roller 38.

46 is a label guide stand arranged between the label peeling plate 45 and the large diameter roller 38; 49 is a label 25 with weight, unit price,
A printer drum 50 is used to print prices, etc., and a hammer 50 is used to press the label 25 onto the drum 49.

24 is a stopper for positioning the label 25 carried into the label holding port 7, and is screwed to the bottom surface of the box 3 along the label holding port 7.

Reference numeral 26 denotes label support bars arranged at regular intervals within the holding port 7.

The operation of the above structure will be explained.

For example, in a weight value marking device, when a weight is weighed on a scale, a predetermined label 25 is pressed against a printer column 49 by a hammer 50 in the label printing machine 1 based on the weighed value, and the weight, unit price, and price are printed on the label 25. etc. are printed.

Next, when the mount 51 and the label 25 are fed in the direction of the arrow, the label 25 is peeled off from the mount 51 by the peeling plate 45, passes over the guide 46, and the end of the label 25 is transferred to the large diameter roller 38 and the presser roller. 44.

Then, although this man-diameter roller 38 is rotating at high speed,
The label 25 is wound up at high speed and conveyed between each belt 39 and the guide plate 22 at high speed in the direction of the arrow, enters the holding port 7, hits the stopper 24, and is stopped by the holding port 7.

When the label 25 is in the holding hole 7, the game 1-
10 is horizontal and the air blowing path is blocked, and air is sucked by the suction port 8b of the fan 8 through the holding port 7, the notch groove 65, and the communication hole 12, and the sucked air is passed to the fan 8. from the air outlet 8a to the small room 6
It is blown out of the pasting box 3 through the upper chamber 6a.

Therefore, before the label 26 leaves the belt conveyor 23, it is sucked through the notch groove 65 and brought into contact with the box bottom plate 3a.

When the label 25 is completely separated from the belt conveyor 23, the label 25 advances in the direction of the arrow along the box bottom plate 3a, hits the stopper 24, and is sucked and held in the holding port 7.

By the way, if there were no notch groove 65, about half of the label 25 would be sucked through the holding port 7 when it leaves the belt conveyor 23, and the label 25 would be fed at high speed in the direction of the arrow. Because of this, there is a risk that the object may fly under the stopper 24 without hitting the stopper 24, as shown by arrow 2 in FIG.

According to this embodiment, the problem of looseness does not occur.

As described above, the label 25 that has entered the holding port 7 is sucked and sticks to the bar 26, and is held in the holding port 7 by suction.

Next, the product 28 is brought under the holding port 7, and the connecting rod 17
When the gate 10 is raised, the gate 10 rotates 90 degrees and becomes upright.

Then, the air blown from the outlet 8a of the fan 8 is blown toward the holding port 7, and the blown air causes the label 25 inside the holding port 7 to fly in the direction of arrow C, and the product 28 is It can be pasted at a designated location.

As described above, according to the structure of the label holding section in the label sticking device of the present invention, an appropriate number of cuts are made on the bottom plate of the label sticking device main body from the label holding recess toward the label peeling plate and communicating with the suction section of the fan. Since the notch groove is formed, the label conveyed toward the label holding recess is first sucked through the notch groove, and then sucked through the holding recess, so to speak, in two stages. It gets sucked in right in front of me.

Therefore, the label will not pass under the holding recess.
