Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a nameplate affixing device that simultaneously punches out a nameplate from nameplate printing paper and affixes it to an object.

[Conventional technology]

As shown in FIG. 1, a conventional nameplate pasting device uses a knife edge 4 to separate the nameplates 1 from a hoop material 3 pasted on a mount 2 at appropriate intervals by punching out printed nameplates 1 one by one in advance, as shown in FIG. , the nameplate 1 is suctioned by a suction piece 5 having a vacuum suction hole 6 and attached to an object (not shown) at a different position.

[Problem to be solved by the invention]

However, with such conventional nameplate affixing devices, it takes extra man-hours to punch out nameplates one by one from nameplate printing paper and affix them to the mounting paper in advance.
In addition to increasing the cost, when punching out the nameplate 1, there may be a misalignment between the center of the outer shape and the center of the print, and the position where the nameplate 1 is separated by the knife edge 4 may be uneven, causing the nameplate 1 to be attached to the suction piece 5. Since positional deviations tend to occur during suction, high precision cannot be expected in the positioning of nameplates on objects, and the defect rate due to deviations in the affixing positions is high.

In particular, when a scale is printed on the nameplate for adjusting the operating characteristics of the device, if the label is misaligned, the scale becomes inaccurate and the adjustment cannot be performed accurately.

SUMMARY OF THE INVENTION An object of the present invention is to provide a nameplate affixing device that can simultaneously punch out a printed nameplate and affix it to an object, and affix the nameplate to a required position on the object with high accuracy.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a nameplate printing paper feeding means for sequentially feeding in the longitudinal direction a nameplate printing paper on which a nameplate is printed and marks for longitudinal and lateral positioning with respect to the nameplate are attached; and a press device that punches out a nameplate from the nameplate printing paper using a cutting die consisting of a die and affixes the nameplate to an object using the die, and positions the nameplate with respect to the die before punching out the nameplate. Therefore, a longitudinal direction sensor detects the longitudinal positioning mark with respect to the nameplate and stops the feeding operation of the nameplate printing paper feeding means with respect to the cutting die; The printer is configured to include a lateral sensor that corrects the lateral position of the printing paper.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 2 to 7.

FIG. 2 is a diagram showing an example of a pattern of nameplate printing paper. Reference numeral 11 indicates nameplates printed at predetermined intervals in the longitudinal direction of the nameplate printing paper 10, and reference numeral 12 indicates longitudinal positioning of each nameplate attached by printing to the margin portion of the nameplate printing paper 10 where the nameplate 11 is not printed. Marks 13 and 14 are horizontal positioning marks, and the longitudinal positioning mark 12 is provided so that its right edge coincides with the center line of the nameplate 11.
The lateral positioning marks 13 and 14 are provided perpendicularly to the longitudinal positioning mark 12.
In order to increase positional accuracy, it is best to print these longitudinal positioning marks 12, 13, 14 at the same time as the name plate 11, but they may also be slits or punched holes.

In this embodiment, the nameplate 11 is a thermal relay (which detects the heat generated by overload current by the amount of deformation of the bimetal, and cuts off the current to the load circuit when the amount of deformation reaches an amount corresponding to the current value that should be operated). relay)
It is attached to the operating current adjustment dial. Nameplate 11
As shown in FIGS. 2 and 3, it consists of a circle and scales indicating operating current values provided at regular intervals along the circumference of the circle. This nameplate 11 is attached to a rotatably mounted operating current adjustment dial, and after being attached, it rotates together with the dial and stops at a predetermined scale position to set a predetermined operating current. Therefore, if a positional shift or an angle error (rotational shift in the circumferential direction) occurs during pasting, the scale will indicate an inaccurate operating current value, making it impossible to set the product operating characteristics correctly.

FIG. 3 shows the arrangement of each part of the nameplate affixing device. 1
Reference numeral 5 denotes a hoop material in which a nameplate printing paper 10 (with pressure-sensitive adhesive applied to the back surface) and a mount 16 shown in FIG. While applying braking force to the shaft 17 using a brake (not shown), the nameplate printing paper 10 and the backing paper 16 are separated and pulled out from the hoop material 15, and only the backing paper 16 is wound around the shaft 18. and the die 20, and after punching out the nameplate portion 11 there, the remaining part 2 of the nameplate printing paper 10 is
1 is wound onto a shaft 22. Winding shaft 1
As drive motors 8 and 22, nameplate printing paper 10
A motor capable of instantaneous stopping is used to enable highly accurate positioning. The die 20 has a corrugated surface 20a with protrusions along the traveling direction of the paper 10 on its surface so that the back surface of the nameplate printing paper 10 can be easily attached with adhesive glue, thereby reducing the contact area. Furthermore, this surface is hard chrome plated.

The punch 19 of the press device has a vacuum suction hole 23 opened at its end surface, and this vacuum suction hole 23 is connected to a vacuum pump (not shown) by a suction pipe 24. The object 25 (in this embodiment, it is an operating current adjustment dial rotatably provided on a thermal relay) is positioned so as to be centered with the punch 19 at a height corresponding to approximately the bottom dead center of the punch 19. .

Reference numeral 26 denotes reflective photosensors (longitudinal direction sensors) for detecting the longitudinal positioning marks 12 of the nameplate printing paper 10, and one is installed on each side of the punch 19 perpendicular to the paper surface. Reference numeral 27 denotes reflective photosensors (lateral sensors) for detecting the lateral positioning marks 13 and 14 of the nameplate printing paper 10, and these are also installed one each on each side of the punch 19 perpendicular to the paper surface.

28 and 29 are nameplate guides, nameplate printing paper 10
In order to correct the lateral position of the paper, the paper is configured to be movable in a direction perpendicular to the plane of the paper by a drive mechanism, which will be described later. 30 and 31 are guide rollers.

Next, the nameplate positioning procedure will be explained with reference to FIG.

FIG. 4a is an explanatory diagram of longitudinal positioning, and A,
B is a measurement point for longitudinal positioning, and when the photo sensor 26 detects the right edge of the longitudinal positioning mark 12 facing the nameplate paper winding direction, the longitudinal center of the nameplate 11 is located at the punch 19.
The winding shafts 18 and 22 are stopped from being driven.

Figure 4b is an explanatory diagram of lateral positioning; C, D
is the measurement point for lateral positioning.

Here, assuming that the output of the photo sensor 27 is ON when the measurement point is in the dark area of the paper, when the sensor outputs corresponding to measurement points C and D are both OFF, that is, both measurement points C and D are When the nameplate 11 is on the inside according to the lateral positioning marks 13 and 14, it is determined that the lateral center of the nameplate 11 coincides with the center position of the punch 19. In the positioning states shown in FIGS. 4a and 4b above, the longitudinal center of the nameplate 11, the lateral center, and the center of the punch 19 are aligned, and the nameplate is aligned with the punch 19. This means that there is no positional shift or rotational shift in the circumferential direction. That is, if any of the nameplates is misaligned, one of the longitudinal and lateral positioning marks printed near the nameplate will necessarily be misaligned from the measurement point. If the sensor output corresponding to measurement point C is ON and the sensor output corresponding to measurement point D is ON,
If it is OFF, the nameplate printing paper 10 is moved in the direction of arrow A. Conversely, if the sensor output corresponding to measurement point C is OFF and the sensor output corresponding to measurement point D is ON, the nameplate printing paper 10 is moved in the direction of arrow A. Move it in the direction of to correct the lateral position.

FIG. 5 shows an example of a lateral position correction mechanism. In the figure, 32 is a feed screw for laterally moving the name plate guides 28 and 29, and 33 is a drive motor thereof.
8 and 29 are moved laterally together with the nameplate printing paper 10.

FIG. 6 shows another example of the lateral position correction mechanism,
Wave surface 34 to prevent nameplate printing paper from adhering to the surface
Moving tables 34 and 35 on which A and 35a are formed
The nameplate printing paper 10 is sandwiched between clampers 38 and 39 operated by clamp cylinders 36 and 37, and is laterally moved by a feed screw 32. Drive motor 33 in FIGS. 5 and 6
Both are motors that can be stopped instantaneously.

FIG. 7 is an explanatory diagram of the nameplate pasting operation.

The press device is activated by signals from photosensors 26 and 27 that detect that the nameplate portion 11 of the nameplate printing paper is set in the correct position with respect to the punch 19.
The punch 19 descends. a is a vacuum suction hole 23 opened in the end face of the punch 19 to hold the nameplate printing paper 10.
This shows the nameplate part being absorbed. punch 19
further descends, and as shown in Figure b, the punch 19
The nameplate portion 11 punched out with the die 20 is carried to the attachment position while being attracted to the end face of the punch 19, and is attached to the object 25. After pasting, the vacuum suction is stopped and only the punch 19 is raised as shown in c of the same figure.

Therefore, if the object 25 and the punch 19 are aligned in advance, there will be almost no deviation in the position or angle of the affixed nameplate.

In order to prevent the printing paper 10 from adhering to the die 20 and the movable tables 34 and 35, wave surfaces are formed on the surfaces of these parts to make it difficult for the nameplate printing paper to adhere, and guide rollers 30 and 31 are used to prevent the printing paper 10 from adhering to these parts. It is sufficient to always leave a slight gap between the surface of each part and the nameplate printing paper so that even if it sticks, it can be peeled off by the winding force.

In the above embodiment, the nameplate is positioned both in the longitudinal and lateral directions using positioning marks. The nameplate printing paper may be fed intermittently at approximately constant intervals and longitudinal positioning using positioning marks may be omitted.
Even if the nameplates are printed on the nameplate printing paper at intervals, depending on the required accuracy, the lateral positioning mark may be omitted and the lateral positioning may be performed using only the nameplate guide.

As the nameplate printing paper feeding means, a dripping method using a feeding roller may be used instead of the winding method as shown in the above embodiment.

Further, in the above embodiment, a hoop material is used in which the nameplate printing paper and the mount are rolled together, but the mount may be omitted if the nameplate printing paper is unwound while peeling off the front and back sides.

In addition to the vacuum suction method for holding the punched nameplate on the end of the punch, there are other methods such as pricking the nameplate with a needle provided on the end of the punch.

[Effects of the Invention] As described above, the nameplate pasting device according to the present invention attaches positioning marks in the longitudinal direction and the lateral direction to the nameplate printing paper, and at the same time detects both of the above-mentioned positioning marks before punching out the nameplate printing paper. The feeding operation of the printing paper is stopped at a predetermined position relative to the cutting die, and the horizontal misalignment of the nameplate printing paper is corrected, so that the nameplate can be punched out and at the same time placed on the target object with high precision. It can be pasted.
