Abstract

<P>PROBLEM TO BE SOLVED: To provide an apparatus for sticking a label without staining a surface of a sticking object. <P>SOLUTION: According to the structure of the apparatus, when the label is stuck to the sticking object, a gap G is secured between an upper surface of a glass sheet 90 as the sticking object and a sticking roller 3 so as not to scrape the surface of the glass sheet 90 by the roller or the like, and a front end of the separated label 98 is inserted into the gap. By lifting the entire body of the glass sheets 90 piled up on each other, bringing a paste surface at the front end of the label 98 into contact with the glass sheet 90, and rotating the sticking roller 3, sticking of the label and glass delivery are carried out in cooperation with each other. A delivery roller 5 on a downstream side makes contact with a lower surface of the glass sheet 90, and therefore it does not stain the upper surface. Further the apparatus is comprised of a thickness absorbing section 7, and therefore even if the thickness of each glass sheet 90 is uneven, the thickness absorbing section 7 can absorb the unevenness, to thereby make the sticking surface of the glass sheet horizontal. <P>COPYRIGHT: (C)2006,JPO&NCIPI

And a proximity device for bringing the transparent plate and the delivery roller close to each other when the label is supplied to the gap from the label device.
According to the said structure, there exists an effect which can be affixed on a transparent board immediately, after printing a necessary matter on a label, without polluting the surface of a transparent board. For this reason, there is an advantage that it is difficult to make an error in the correspondence between the sample and the label.

  According to the label sticking device of the present invention, the surface of the transparent plate is not soiled, and there is an effect that it is possible to automate the label sticking that has conventionally relied on manual work.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is an overall schematic view of a label printer according to the present invention. The label printer includes a label sticking device 1 and is configured to stick a label supplied from a printing mechanism to an object.

First, the configuration of a printing mechanism that is a label supply device will be described.
As shown in FIG. 3, a label 98 is attached to the glassine 99 wound around the label stocker 40, and printing is performed on the label 98 by the print head 45. 44 is a platen. The thermal transfer ribbon 42 is wound around a thermal transfer ribbon stocker 41 and is wound around a transfer ribbon winding 43 via a print head 45.
The glassine 99 is bent at the peeling portion 46, and the label 98 is peeled off from the glassine 99 and supplied to the label applying device 1. Specifically, as will be described later, the label 98 is stopped in a state where the tip of the label 98 has entered under the sticking roller 3. An adhesive is applied to the back surface of the label 98 so that it can be easily adhered to the glass plate 90.
47 is a peeling roller, and 48 is a sensor.
The above-described configuration of the printing mechanism is an example of a conventionally known mechanism, and other mechanisms can be employed.

  The label attaching device 1 has a glass plate holding device 2, and a glass plate 90 to which a label 98 is to be attached is stocked. The glass plate holding device 2 is provided with a stock magazine 20 and an elevator 21 for raising and lowering the inside of the stock magazine 20. The elevator 21 is raised by driving the raising and lowering mechanism 22 to raise the glass plate 90 and supplied from the printer side. The label 98 to be used is stuck on the glass plate 90.

  The glass plate 90 is a preparation in this embodiment, and is a thin rectangular glass plate of about several millimeters as shown in FIG. And the sticking part 91 is formed in one edge part, The coating material about 10-15 micrometers thick is apply | coated to this sticking part 91. FIG.

The stock magazine 20 holds and holds a plurality of the glass plates 90, and a label 98 is attached in order from the uppermost glass plate 90, and is sent to the next process by the feed roller 5 and the shooter 6.
The elevator 21 is moved up and down by the drive of the lifting mechanism 22, and is lifted every time the glass plate 90 is sent out to raise the next glass plate 90 to the label attaching position.

As shown in FIG. 4, the glass plate 90 is stopped so as to form a predetermined gap G between the glass roller 90 and the label 98 peeled off by the peeling portion 46, and the leading end is buried in the gap G. It comes to stop at.
In this state, the elevator 21 rises, the label 98 is pressed against the glass plate 90 by the application roller 3 as shown in FIG. 5, and the label 98 is applied while being fed in the direction of the feed roller 5 by the rotation of the application roller 3. Done. The glass plate 90 with the label 98 attached is sent to the next process by the feed roller 5 and the shooter 6.
In the above configuration, the affixing roller 3 does not contact the surface of the glass plate 90 but only contacts the label 98, so that the affixing roller 3 does not contaminate the surface of the glass plate 90.

  The rising position of the glass plate 90 is detected by the upper limit detection sensor 4 so that the step L from the upper surface of the glass plate 90 to the upper end 25 of the magazine corresponds to 1.5 sheets of the glass plate 90 as shown in FIG. The rising stop position of the glass plate 90 is adjusted. Thereby, only the uppermost glass plate 90 is sent to the feed roller 5 side.

As shown in FIG. 6, the thickness absorption part 7 is provided on the elevator 21, The thickness absorption part 7 absorbs the thickness of the sticking part 91 shown in FIG. 2, and keeps the glass plate 90 horizontal. It has become.
That is, the tilting plate 70 is pivotally supported by the support shaft 71 and is pressed upward by the spring 72, and the glass plate 90 is placed thereon. As shown in FIG. 6, when there are many glass plates 90, the deflection amount D is large due to the weight of the glass plates 90, and the accumulated thickness of the pasting portion 91 is also eliminated. Further, as shown in FIG. 7, when the glass plate 90 is small, the deflection amount D is also small, and the thickness to be eliminated is also reduced according to the amount of the glass plate 90.
If the spring force of the spring 72 is adjusted to an appropriate value, the thickness of the affixing portion 91 is eliminated and the glass plate 90 always maintains a horizontal position, so that the label 98 can be affixed smoothly.

Next, the operation will be described.
The label 98 is affixed to the glassine 99 which has been treated so as to be peelable by applying a release agent, wound on a roll, and attached to the label stocker 40. The label 98 fed out from the label stocker 40 is overlapped with the thermal transfer ribbon 42 and supplied to the print head 45 and the platen 44 to perform printing. The sensor 48 is a sensor for detecting the leading edge of the label by the amount of light transmitted through the portion where the glassine 99 alone and the glassine 99 / label 98 overlap in order to determine the position to start printing. The platen 44 and the ribbon transfer ribbon take-up 43 are rotated by applying power from a motor (not shown).

The label 98 printed out from the printing mechanism comprising the head 45 and the platen 44 peels off the label 98 from the mount 99 by pulling the mount 99 back at an acute angle and pushes it out in the direction of the affixing roller.
The peeled label 98 stops the peeling by letting the tip of the label 98 into the gap G under the sticking roller 3. To stop, the stop position can be controlled by obtaining print data in which the label length is previously incorporated from an external computer.
Next, the elevator 21 is raised, the glass surface comes into contact with the tip of the peeled label 98, the adhesive surface applied with the adhesive applied to the back side of the label 98 comes into contact, and simultaneously, the pasting roller 3 and the feeding roller 5 are rotated and pasted. The glass 90 is sent out.

  As described above, the upper end 25 of the magazine is lower than the upper limit position by the level difference L corresponding to 1.5 sheets of glass thickness, so that only the uppermost glass plate 90 is transported and is lower than the second sheet. The glass plate 90 is stopped by the wall and is not carried out. Since the auxiliary feeding roller 5 rubs the lower surface of the glass plate 90, the surface is not soiled.

The upper limit detection sensor 4 detects that the upper surface of the glass plate 90 is at the label attachment position. It is also used to form a gap G between the application roll 3 and the upper surface of the glass plate 90 when the label 98 is peeled off. Follow the steps below.
1. When the feeding of the previous glass plate 90 is finished, the elevator 21 is raised until the upper surface of the next glass plate 90 is detected by the upper limit detection sensor 4.
2. The elevator 21 is lowered to create a gap G into which the tip of the peeled label 98 enters.
The drive of the elevator 21 is preferably determined by using an AC motor with an angle detection encoding or a stepping motor.

As described above, in the glass plate 90 of the type in which the pasting portion 91 is coated, the thickness of the paint is usually 10 to 15 μm. When the glass plates 90 are stacked, the pasting portion 91 portion becomes thick and a height difference is generated, and when 100 sheets are stacked, a height difference of 1 mm or more is generated. Therefore, the horizontal state of the glass plate 90 in the stock magazine 20 differs depending on whether the number of glass plates 90 is large or small.
For example, when 100 sheets of 10 μm are stocked, it is 1 mm, and when 50 sheets are stacked, the height difference is 0.5 mm. 1 mm corresponds to the thickness of one piece of glass.

As described above, in this embodiment, one side of the tilting plate 70 is supported by the support shaft 71, and the other one can be moved up and down by the spring 72. When the weight of the glass plate 90 is added, the support shaft 71 becomes a fixed end, and one side of the tilting plate 70 sinks to a position where it is suspended from the deflection of the spring 72. When the weight of the glass plate 90 is heavy, the deflection amount D of the spring 72 is large, and when the number of glass plates 90 is small and the weight is light, the deflection amount D of the spring 72 is small. Since the deflection amount D of the spring 72 is proportional to the weight, the affixing portion 91 can be kept horizontal regardless of the number of glass plates 90 to be stocked.
Although the case where the glass plate 90 is used as the transparent plate has been described in the above description, the configuration of the present invention can be applied even if the object to be labeled is plastic.

A control block diagram for realizing the above operation is shown in FIG.
Receives data for printing from a computer and information on the size of a label to be pasted from an external interface.
The received print data is drawn and developed in a memory using a dot matrix such as characters and bar codes, and sent to the print head.
The printing position is controlled based on the label tip position detected by the printing position detection sensor, and peeling is performed simultaneously with printing.
After peeling, the glass is fed out by the pasting motor drive circuit, and then the elevator motor is rotated up and down while monitoring the upper limit position detection sensor.
Next, if the next print data is received, the next printing and pasting operation is performed. A CPU is mounted to control them as a whole.
