Description

In particular, the present invention relates to a label sticking device that reduces noise and cushions impact force when sticking a label on an object to be stuck using magnetic force.

2. Description of the Related Art Conventionally, there has been known a label sticking device that holds a suction plate with a plurality of springs.
However, this kind of label sticking device sucks and holds the label with the suction plate and presses it against the adherend to stick the label, which puts a burden on the springs and screws that support the suction plate and makes it durable. There is a problem of lacking. For this reason, the springs and screws are periodically replaced, or a material having strength is used in consideration of durability.
In order to cope with the above problem, there is known a label sticking device that controls the pressing force on the adherend by changing the compression force of the spring (for example, the conventional technique of Patent Document 1 (FIG. 3)). reference).
However, the conventional label sticking apparatus has to adjust the spring pressure each time the adherend changes in hardness, but the spring pressure is very difficult to adjust and the working time can be several tens of minutes. Since there are many, there existed a problem of causing the work efficiency to fall.
Therefore, in Patent Document 1, pressure adjustment is achieved by causing the suction plate that has attracted the label to slip by a slip clutch provided in the power transmission portion of the advance / retreat mechanism. That is, the slip clutch is configured to slip when the pressing force that presses the suction plate against the adherend reaches a predetermined pressure. This is intended to reduce the impact force applied to the.
However, the label sticking device of Patent Document 1 has a problem in that the size of the device is unavoidable, for example, it is necessary to provide a timing clutch, including a slip clutch, in the advancing / retracting mechanism that moves the suction plate back and forth.
Japanese Patent Laid-Open No. 10-81320

Then, the sheet is wound around the backing sheet winding unit 59 via the auxiliary roller 62. The label L on which desired information is printed by the printing unit 57 is peeled off from the mount 60 and is temporarily held by the adsorbent 1 waiting in the vicinity of the printing mechanism 50 at the peeling unit 58 to which the mount 60 is turned. Is done. Then, the label L temporarily held by the adsorbent 1 is conveyed and pressed toward the object 52 by the cylinder 20 that moves forward and backward in synchronization with the conveyance of the object 52 on the conveyor 51 and is pasted. The

Next, an embodiment of the adsorbent 1 according to the present invention will be described mainly based on FIG. 2 and FIG.
FIG. 2 is a partially broken side explanatory view showing the main part of the adsorbent 1, and FIG. 3 is an explanatory view of a plane viewed from the direction of arrow III in FIG.
The adsorbent 1 is made of a metal such as aluminum, and mainly includes a first adsorbent body 2 and a second adsorbent body 10.
The first adsorbent body 2 is attached via a support plate 3 joined to the tip portion of the cylinder 20 and four support screws 5 with springs 4 provided on the support plate 3. Part 6 is formed. Further, the “plane” portion opposite to the surface supported by the support screw 5 and the entire surface of the flange portion 6 are covered with a first magnetic body 7. That is, the flange portion in FIG. 2 is provided on the first magnetic body 7 so as to be hooked on the flange portion 6 and the flat portion 8 located on the opposite side of the surface supported by the support screw 5. A first folded portion 9 is formed which includes a side folded portion 9a facing the side surface 6 and an upper folded portion 9b.

The second adsorbent body 10 is provided so as to cover the first adsorbent body 2, and the adsorbing portion 11 having the adsorbing surface 11 a on which the label L is adsorbed and temporarily held is provided on one side. In addition, a hollow portion 12 is formed by surrounding the case main body 18 so that the suction surface 11a of the suction portion 11 becomes an outer surface. The suction part 11 is formed with a plurality of suction holes 13 communicating with the hollow part 12.
Further, the second adsorbent body 10 is provided with a hose 14 having one end communicating with the hollow portion 12 and the other end connected to a vacuum device (not shown). By operating, the air A is sucked from the hose 14, the hollow portion 12 becomes negative pressure, the air A is sucked to the hollow portion 12 side from the suction hole 13 formed in the suction portion 11, and the label L is attracted to the suction portion 11. Specifically, it is sucked and temporarily held by the suction surface 11a.
Furthermore, a second magnetic body 15 is provided on the outer surface of the opposite position with the hollow portion 12 being separated from the attracting portion 11. The second magnetic body 15 is provided opposite to the first magnetic body 7, and a second folded portion 17 is formed in the same manner as the first magnetic body 7. More specifically, the flat surface portion 16 facing the flat surface portion 8 of the first magnetic body 7, the second side surface bent portion 17a facing the side surface bent portion 9a, and the first upper surface folded portion 9b. A second folded portion 17 formed of a second upper surface folded portion 17b opposite to the upper surface is formed.

The first and second magnetic bodies 7 and 15 are both magnetized to the same pole (S pole or N pole), and a little between the first magnetic body 7 and the second magnetic body 15. Is magnetized with an equivalent magnetic force to the extent that a large gap G is generated. That is, the first and second magnetic bodies 7 and 15 have the same polarity and are magnetized with an equivalent magnetic force such that a slight gap G is generated between them, so that the first adsorbent body 2 can be magnetized. The second adsorbent body 10 provided so as to cover the second adhering body body 10 includes a second folded portion 17 including a flat surface portion 16, a side surface folded portion 17 a and an upper surface folded portion 17 b formed on the second magnetic body 15. Are separated from each other by a magnetic repulsion against the first folded portion 9 composed of the flat surface portion 8, the side surface folded portion 9 a and the upper surface folded portion 9 b of the first magnetic body 7. It floats in the so-called floating state.
Reference numeral 19 denotes a magnetic coupling body that couples the first and second magnetic bodies 7 and 15. By connecting the first and second magnetic bodies 7 and 15 with the magnetic coupling body 19, the magnetic coupling body 19 is provided. It is intended to equalize.
Moreover, the 1st and 2nd magnetic bodies 7 and 15 can be created with a permanent magnet or an electromagnet. In the present embodiment, the description will be made on the assumption that “permanent magnet” is adopted, and reference will be made to the explanation in the case where “electromagnet” is adopted as necessary.

Next, the usage example of the label sticking apparatus using the adsorption body 1 of this invention is demonstrated.
The label L peeled off from the mount 60 by the peeling unit 58 is sucked and temporarily held by the suction body 1 waiting in the vicinity of the printing mechanism 50 and is synchronized with the conveyance of the object 52 on the conveyor 51. Then, the cylinder 20 is moved forward and backward to be carried toward the object 52 to be pasted.
Mainly, as shown in FIG. 2, the support plate 3 joined to the tip portion of the cylinder 20 and the adsorbent 1 attached via a support screw 5 with a spring 4 provided on the support plate 3 are The label L temporarily held by the action of the cylinder 20 advanced toward the object 52 is pressed and pasted.
When the label L is affixed to the adherend 52, the first magnetic body 7 and the second magnetic body 15 are repelled by magnetic force, and the first adsorbent body 2 provided with the first magnetic body 7 is used. On the other hand, the second adsorbent body 10 provided with the second magnetic body 15 provided so as to cover it is released by the repulsive force of the magnetic force, and enters the floating state with the gap G interposed therebetween. , The impact applied to the adsorbent 1 when the label L is applied is absorbed and buffered. As a result, the impact applied to the support screw 5 and the support plate 3 with the spring 4 and the cylinder 20 joined to the support plate 3 is reduced. The durability of the “attachment support component” of the adsorbent 1 such as the spring 4 and the support screw 5 is improved.
The shock buffering action is not only the repulsive force of the magnetic force between the flat surface portion 8 of the first magnetic body 7 and the flat surface portion 16 of the second magnetic body 15 provided so as to face the first magnetic body 7. Side surface bent portion 9a of the magnetic body 7, the side surface bent portion 17a of the second magnetic body 15 provided opposite thereto, further, the upper surface folded portion 9b of the first magnetic body 7, and this Since the upper surface turning portion 17b of the second magnetic body 15 provided so as to face the surface is repelled by magnetism, not only in the vertical direction, which is the forward / backward direction of the cylinder 20 in FIG. Even work. Thereby, since there is no contact between the metals of the first and second adsorbent bodies 2 and 10 made of metal (aluminum), generation of noise can be minimized.

In the above embodiment, the “permanent magnet” has been described as an example of the first and second magnetic bodies 7 and 15. However, when the “electromagnet” is employed, the first and second magnetic bodies 7 and 15 are connected to a voltage device (not shown) and connected to the voltage device. The repulsive force due to the magnetic force of the first and second magnetic bodies 7 and 15 can be adjusted depending on the voltage level. Therefore, the free / floating state of the first and second magnetic bodies 7 and 15 can be adjusted by adjusting the voltage of the voltage device (not shown) according to the “hardness” of the object 52 to be adhered. It is possible to easily realize an absorption / buffer state suitable for different impacts due to the difference in the “hardness” of the patch 52.

The “electromagnet” is demagnetized when a power supply (not shown) is turned off, and the repulsive forces of the first and second magnetic bodies 7 and 15 excited to the same polarity disappear. In particular, when the repulsive force between the upper surface folded portion 17b of the second folded portion 17 and the upper surface folded portion 9b of the first folded portion 9a disappears, the second adsorbent body 10 tends to fall downward in FIG. However, since the second folded portion 17 provided so as to cover the flange portion 6 of the first adsorbent body 2 gets on the flange portion 6 and is blocked, the second adsorbent body 10 falls. There is nothing.

It should be noted that the configuration and operation of the above-described embodiment are examples, and it goes without saying that they can be changed as appropriate without departing from the spirit of the present invention.

For example, in the above-described embodiment, the suction part 11 and the case main body 18 surrounding the suction part 11 are described separately. However, the present invention is not limited to this example, and is integrally molded. The hollow portion 12 may be formed by the “case body”.

In the above-described embodiment, for the sake of explanation, the example in which the adsorbent 1 moves back and forth in the up and down direction has been described. However, the present invention is not limited to this, and the cylinder 20 as the back and forth mechanism is disposed horizontally. Alternatively, the adsorbent 1 joined to the tip of the cylinder 20 may be advanced horizontally and the label L1 temporarily held by the adsorbent 1 may be attached to the side surface of the object 52. As described above, even when the adsorbing body 1 is advanced in the horizontal direction, that is, in a so-called “lateral position” state, the side bent portion 9a of the first magnetic body 7 and the second bent portion 9a provided opposite thereto are provided. In the state where the side bent portion 17a of the magnetic body 15 repels in the vertical direction and the front-rear direction by the magnetic force and the gap G is separated, the first adsorbent body 2 and the second adsorbent body 10 are released and floated. In addition, since the flat portions 8 and 16 are repelled by the magnetic force in the horizontal direction and are kept in a floating state, the “horizontal” state can be used.
