Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a pressure-sensitive adhesive label to simply press the application head against the surface of the target article in response to irregularities, slopes, etc. of the surface. The present invention relates to a label sticking device that can accurately stick a label on a surface to which it is applied without requiring any special operations.

Various methods have already been proposed for means for peeling off a pressure-sensitive adhesive label from a backing tape, holding it by suction, and pasting it on the surface of an object to be pasted.

However, in the pasting heads used in conventional label pasting machines to perform both label holding and pasting operations, the surface holding the label moves straight against the target pasting surface, and then presses the label as it is. The surface to be adhered is, in principle, smooth or nearly smooth.

Therefore, if the label application surface is not parallel to the end face of the label application head, accurate label application will not be possible.

In order to deal with this situation, attempts have generally been made to attach a highly cushioning material such as a sponge to the label holding surface of the labeling head, and to have the label held by this material. However, this cannot solve all problems; for example, when attaching labels at high speed, if the article is not fed in the correct position when attached to the applicator head, incorrect labeling may occur. This can lead to problems such as labels peeling off during handling of the product after it has been pasted, or malfunctions due to frequent application of excessive external force to the label-holding direction of the label-pasting head. There is a need to solve it.

The present invention solves the above-mentioned problems that have been dealt with unsolved in the past, and provides a label pasting means that can immediately respond to the condition of the surface to be pasted and apply labels smoothly and without difficulty. It's about doing.

In the present invention, when applying a label to a surface to be applied, simply by pressing the application head, the label holding surface automatically corresponds to the surface to be applied. The label is applied and the reaction force is used to forcefully press the label to ensure that the label is attached.

In addition, the present invention is capable of attaching a label when the label holding surface of the label head comes into contact with the number of pieces 1 to be attached and a thrust force of more than a certain level is applied to ensure that the label is attached. This made it possible to confirm the following at the same time.

According to the present invention, in a label pasting machine using pressure-sensitive adhesive labels, the air suction holding type label pasting head that moves in a reciprocating straight line automatically maintains the normal posture of the label holder part vertically, horizontally, and vertically. When the label held by the label holder m1 is pressed against the surface to be applied of the handled article by moving forward of the label application head in a freely swingable state with a restoring function, the label holder portion is Applying an elastic force or thrust to the surface to be applied and pressing it, and displacing it in a direction corresponding to the surface to be applied,
This allows the held label to be applied to the surface of the article by blending it with the surface to which it is applied.

In addition, in the present invention, the movable support part of the label holder is retracted by pressing reaction force at the same time as the pasting head is activated, and when the moving amount exceeds a set amount, the appropriate pressing force is electrically detected and the label is removed. A mechanism was added to automatically check the adhesion.

Furthermore, in order to ensure such pasting operation, the present invention includes:
A box-shaped head main body is fixed to the tip of a driving body that moves in a reciprocating straight line, and a movable body that is movable back and forth is provided within the main body so that its axial center line coincides with an extension of the operating center line of the driving body.

A suction plate surface is formed with a large number of air intake holes communicating with the chamber, and the air intake chamber is connected to an air intake source.

In addition, in the present invention, the front surface of the label holder of the applicator head attached to the tip of the drive body is made into a circular curved surface, and the spherical holding connection part is provided at the center of the back to enable the swinging convexity. The center of the connecting part and the head attachment are connected with the rear part of the body by a tension spring to have an automatic center return function, and the front side of the label holder is provided with a cushion layer and has a large number of intake holes communicating with the internal intake chamber. An open suction plate surface was formed.

Furthermore, in the present invention, a pair of reciprocating drive bodies are provided at positions spaced apart from each other by an appropriate dimension left and right or up and down from the center of the mounting body of the label sticking head, and the movable ends of the drive bodies are connected to positions facing the back of the label holder. By operating this reciprocating drive body, the label holder is positively displaced so that the label can be pasted on the surface to be pasted in the shape of curve II'f1.

In the present invention, a mechanism is provided to move the labeling machine back and forth and back and forth in the radial direction perpendicular to the axis of movement of the labeling head as described in 2. By incorporating a rotating device that can change the direction between the dispensing position and the pasting position into a pasting machine, the inside of hot coils (thin steel plate coils) and other cylindrical articles can be easily attached. This made it possible to attach labels to part of the circumferential surface.

First, the head main body 10 is formed into a box with a rectangular cross section, and is attached to the operating rod 2 by a mounting plate 11 that also serves as a cover for the rear end opening hole 12.
is notched, and a bottom cover 14 is attached to the bottom opening.

The movable body 20 is formed into a rectangular tube shape, and protrusions 21.21 are symmetrically provided on both sides of the main body, and a bushing 23.2 is provided in a function hole 22 that is bored parallel to the protrusions 21, 21.
3 or a slide bearing is fitted, and the protrusion 2 is slidably supported on the guide shaft 15 arranged in parallel at a predetermined interval in the main body 10 via this bush.
The overall length l of the guide shaft 1 is determined to provide a sufficient space within the main body 10 for movement along the guide shaft 15.

A catch piece 24 having a spherical catch 25 formed on the entire surface is inserted and fixed into the front end of the sounding body 20, and a through hole 26 is formed in the center of the catch piece 24, and a hole 26 is formed at the rear of the spherical catch 25. Wide kerfs 27 are formed in the vertical direction on the inner side, and protrusions 28' and 28' are formed at opposite ends of the kerfs 27 and 27, respectively.
It can be inserted freely under L and forward and backward, and has a long hole 28" in the center.
A guide element 28 provided with is fitted.

The label holder 30 is horizontally elongated and has a rectangular shape suitable for handling labels, and includes a holder main body 31 having a depression forming an intake chamber 32 on the front side, and a suction cup 35 attached to cover the depression.
It consists of a spherical seat 33 of an appropriate radius fixed at the center of the back surface of the holding body 31, and a support shaft 34 is provided at the center of the spherical seat 33.
The middle part of the support shaft 34 is formed flat and inserted into the elongated hole 28'' of the guide 28, and the shaft end part 34'
A tension spring 39 is stretched between the center of the seat plate 29 attached to the rear end of the movable body 20, and the spherical seat 33 is in close contact with the spherical catch 25, so that the center of the support shaft 34 is normally aligned with the center of the movable body 20. matches,
This allows the label holder 30 to be supported.

The suction cup 35 of the label holder 30 has a sponge-like cushion layer 38 of a required area and appropriate thickness partially fitted and protrudingly attached to the front surface of the suction cup 35. A plate 37 is integrally attached, and a large number of small diameter intake holes 38 communicating with the intake chamber 32 are arranged at appropriate intervals on the suction plate 37 through the cushion layer 36. The elbow joint 40.40 attached to the upper part and the end joints 42.42 of the intake pipes 41, 41 inserted through and supported by the head mounting plate 11 are connected to the hose 4.
They are connected at 3.43 and connected to a separately installed air intake source.

A cam plate 60 is attached to the upper surface of the movable body 20, and the cam plate 60 can be adjusted in the front and back direction by shifting the dimension appropriately from the center line, and a mounting piece 51 is installed across the center of the upper surface υ1-1p section 16 of the main body 10.
A limit switch 52 is fixedly arranged on the lower surface, and the operating piece 52' of this limit switch 52 is arranged such that the roller 53 attached to the tip comes into contact with the cam 50, and when the moving body 20 retreats, an electric signal is sent to confirm label attachment. This was done in such a way that it was communicated to the necessary parts.

The operating mode of the apparatus according to the embodiment of the present invention constructed as described above is as follows: The label adhering head 1 receives the label at the label adsorption & dispensing position using well-known means and holds the label by suction.
The label holder 3 moves forward by actuating the driver toward the target object that has been moved to the pasting position of the pasting device by a conveyor or the like.
When the label held on the suction plate 37 surface on the front surface of 0 is brought into contact with the target surface A of the object, the suction plate surface of the label holder 30 is held in the label holding state until it is pasted as described above. Since the support shaft 34 protruding from the center of the back of the holding body 31 and the center of the rear end of the movable body 20 are tensioned by a tension spring 39, they move in a state perpendicular to the straight direction, and therefore the label is adsorbed and held on the surface A to be attached. If the surfaces are parallel to each other, the application head 1 moves straight and comes into contact with the surface, which increases the elasticity of the cushion layer 36 and the movable body 2.
0 is movably supported within the head body 10, an equal pressing force is applied to the entire surface of the label by the compressive reaction force of the spring 45 acting on the rear end, and the label can be reliably attached.

As the applicator head 1 moves straight, the label-adhering surface of the article sent to the adhering position is not parallel to the label suction-holding surface, as shown in FIG.

:! : When the applicator head 1 moves forward and the label holder 3
When a part of the label suction holding surface 37 of No. 0 comes into contact with a part of the adhered surface A, the holding body 30 is attached as the base is a spherical seat 33, and as the driving body moves forward. The free side is attached along the spherical seat 25 according to the resistance of the abutted part [the label holder 30 rotates in the direction A, that is, the label holder 30 swings due to the sliding engagement between the spherical seat 33 and the seat 25. The moving body 20 moves in a convex manner, displacing the direction of the label suction holding surface so that it entirely follows the surface to which it is attached, and applying an amount of propulsion force that is permissible in such a state. Acting splash 4
Since the label moves backward against the force of 5, the label is strongly pressed and adhered to the surface to be adhered by the reaction force.

As mentioned above, even if the label application head 1 is tilted to the left or right or up and down with respect to the straight line, the label can be held in the same manner as described above. The body 30 has a spherical seat 33 and a catch seat 25 as its mounting parts.
The swinging motion of the staff allows the label to be freely displaced and placed on the surface to be affixed, allowing the label to be affixed in the same way as in the normal case, and in both the parallel state and the slanted and irregular state. Even in this case, since the back of the label suction surface is formed with a cushion layer 36 of an appropriate thickness, as well as the above-mentioned oscillation ringing mechanism of the label holder 30, the surface to be adhered is not a smooth surface. Even if the surface is slightly uneven or gently curved, the cushion layer 36 can assist in adapting to the surface condition and attaching the label.
This has made it possible to perform labeling operations that are overall accurate and effortless and smooth.

In this operation, when the head 1 moves to the retracting process after pasting the label, if the pressure air is switched and supplied to the intake chamber 32, the pressure will flow through the hole 38 communicating from the intake chamber to the surface of the suction plate 37. The label can be easily transferred to the surface to be affixed, improving work efficiency.

As the labeling head 1 begins to move to the backward step, the reaction force of the spring 45 is gradually removed, the movable body 20 returns to its original position, and the external force acting on the label holder 30 is removed. At the same time, the spherical seat 33 is automatically returned to its normal position by the force of a tension spring 39 tensioned on a support shaft 34 protruding from the center of the spherical seat 33, and becomes ready for the next operation.

In addition, when the movable body 20 moves back and forth during pasting operation, the bushes 23.23 in the protrusions 21.21 on both sides of the movable body 20 move toward the guide shaft 1.
5 and can be moved without any difficulty.
Regarding the sliding movement between the spherical seat 33 and the spherical catch 25, the support shaft 34 is required to maintain that state regardless of the displacement.
The intermediate flat part of the guide element 28 engages with the cut groove 27 of the seat piece 24 through the elongated hole 2 of the guide element 28 in the left-right direction, and the guide element 28
cuts the protrusions 28' and 28' at both ends, and allows the movable body 30 to be displaced both back and forth and up and down within 427.27, without causing any rotational displacement about the shaft 34. It can operate smoothly.

In the process of pasting the label, the movable body 20 together with the label holder 30 receives a required pressing force, and the main body 10
When regressing inward, the preset pressure displacement dimension -
When the movable body 20 retreats, the cam 50 presses down the operating piece 52' of the limit switch 52, and the switch 52 generates an electrical signal. When this is transmitted to a separately provided operating section, the label is removed at that point. It is possible to confirm that the label has been pasted, and even when items are continuously being sent with irregular surfaces to be pasted, it is possible to easily and accurately apply the label. It can be done.

In the above explanation, the label holding surface of the label sticking head is a flat surface, but even when using a curved label holding surface, the label is It is preferable to use a type with a holding surface that can swing freely, so that it can be attached even to the surface of the article that has a concave curve, making automatic label attachment difficult. To explain this in detail with reference to the drawings, as shown in FIG. 6 and FIG. 55 is installed, and this support piece 55 is made hollow with the center aligned with the axis of the operating rod 3 and has an appropriate length.A spherical support piece 56 is provided at the front end of the support piece 55, and a spherical support piece 56 is provided on the outer periphery of the tip. The mounting is done by forming a collar 55', and in front of the support piece 55 is a label holder 60 having an arcuate label suction/holding surface, and a spherical seat 61 protruding from the center of the back side. In addition to the music that is slid onto the spherical seat 56 of the support piece 55, the seat plate 57 is fitted into the tip attachment hole 62' of the connecting shaft 62 planted in the center of the spherical seat 61 and the rear end of the hollow part of the support piece 55.
are connected by a tension spring 58 and attached to the support piece 55 via a spherical seat 61 so as to be swingable.

The label holder 60 is hollow inside to form an intake chamber 63, which is connected to an intake source through flexible piping as in the above specific example, and a cushion layer 64 is provided on the arcuate surface of the front surface.
is provided so that its front surface becomes a label adsorption surface 65,
A large number of small holes 66 are formed so as to extend into the intake chamber 63.

In addition, a pair of fluid pressure cylinders 71 and 71' are symmetrically attached to a mounting plate 70 that is fastened to the collar 55' of the support piece 55 and extends from the center to the left and right. The fork piece 72 attached to the end of each piston rod 71 of the cylinder 71 is attached to the label holder 6.
The bottle 7 is connected to the long hole 67' of the connecting piece 67 attached to the back plate of the bottle 7.
4 are connected to each other so that the label suction surface 65 of the label holder 60 can press or affix a label to the surface to be affixed by operating the fluid pressure cylinder 71.

When operating the labeling head 1A constructed as described above, the operating rod 3 and the labeling head 1A are operated in a state in which they move straight.

In addition, if the surface of the article to be pasted is a curved surface, the label is first applied to the label suction surface 65 of the label holder 60 by a well-known means for the article supplied to the predetermined label pasting position, and then When the posterior vaginal label holder 60 is advanced and pressed against the surface to which it is applied, since the front surface of the label holder 60 is arcuate, the retained label will come into contact with the surface to which it is applied only at its center. Therefore, a fluid operating section (not shown) is installed in the fluid pressure cylinder 71, 71' provided behind the holder 60.
Pressure fluid is supplied from both cylinders 71. γ1/ is actuated to swing the label holder 60 left and right through the connecting piece 67 connected to the piston rod, and the label holder 60 is swung to the left and right through the connecting piece 67 connected to the piston rod. You can also attach a label along this line.

Of course, at this time, the label holder 60 has a sliding fit between the spherical seat 61 and the spherical seat 56 with respect to the support piece 55, and a tension frame between the connecting shaft 62 protruding from the holder side and the seat plate 57 at one end of the support. Since the label holder can be freely swung by the tensile force of the tension spring 58, the label affixing operation can be performed without any trouble.

In the case of this method, in addition to moving the labeling head only in the straight direction, the support arm 3' to which the support piece 55 of the labeling head 60 is attached is attached to the support as shown in FIGS. 8 and 9. 4 is supported so as to be movable up and down by a main body pressure cylinder 5, and is rotatable left and right about a vertical axis inside the support 4 by a rotation mechanism 6 provided on the upper part thereof, and furthermore, this support 4 and the main body pressure cylinder 5 attachment part 7 are attached to the machine body 8 to form a labeling machine, and the labeling machine R is disposed perpendicularly to the article conveyance body such as a conveyor line, and the labeling machine The landing machine R is made to be movable back and forth, and at the label supply position, the tip of the support arm 3' horizontally rotates to either the left or right, and the support arm 3' and the support piece 55 are connected by a fluid pressure cylinder 75. Connect and label pasting head 6
0 is made to be able to rotate downward around the support piece 55 and the pivot pin 54.

With this configuration, for example, as shown in FIG. 9, the labeling head 60 of the labeling machine H can be inserted into a hot coil C such as a thin steel plate, and a label can be pasted on the inner surface of the hot coil C. The operation procedure in this case is shown in FIGS. 9 to 13. First, as shown in FIG. Then, the pasting head 60 is attached by known means.
After that, the pasting head is returned to its original position, and then the pasting machine R is moved forward to enter the pasting head 60 into the inside of the coil C, as shown in FIG. After that, the fluid pressure cylinder 75 is operated to rotate the labeling head 60 downward using the pivot pin between the support arm 3' and the support piece 55 as a fulcrum, and the support 4 is moved into the main flow. When vertically lowered by the pressure cylinder 5, the label applicator head 60 moves toward the inner surface of the coil C via its support arm 3', and first attaches the central part of the label held on the label suction surface to the target surface. (first
(See Figure 1).

Next, the operation fluid pressure cylinder 71 on the right side of the drawing connected to the back of the label holder 60 is operated, and when the piston rod of the cylinder is projected as shown in FIG. 12, the label is inserted through the connecting piece 67 connected thereto. Since the right side of the holder 60 in the figure is pushed, the label holder 60 swings by sliding between the spherical seat 61 at the center of its back surface and the spherical seat 56 on the support piece 55 side, and the coil C is moved smoothly. The label rolls along the inner curved surface of the suction surface and presses the label held on the suction surface to the surface to be adhered.

Therefore, from now on, the piston rod of the operating fluid pressure cylinder 71' on the left side in the figure should be protruded, and at the same time the piston rod of the operating fluid pressure cylinder 71' on the right side in the figure should be extended
When the piston rod 1 is moved back, the label holder 60 is displaced in the opposite direction as shown in FIG. ends.

When the protruding operating fluid pressure cylinder 71' is returned to its original position, the label holder 60 returns to its normal position by the force of the tension spring 58 connected to the connecting shaft 62 at the center of its back surface, and the main fluid pressure cylinder 5 is reversely operated to support the label holder 60. The original state is returned by raising the body 4 and advancing the piston rod of the operating fluid pressure cylinder 75 for changing the direction of the pasting head, and then the work is completed by retracting the pasting machine to the required position. .

By making the label suction and holding surface formed on the front part of the labeling head into an arcuate surface in this way, even if the surface to be pasted is a curved surface, the label can be reliably pasted on that surface. Of course, by making this process automatic, it became possible to carry out the process with high efficiency.

In addition, when employing a label application head with such a curved surface, electric detectors such as microswitches may be installed at appropriate positions at both ends and the center of the front of the label holder for label dispensing and application work. Labels can be applied more accurately if the head is installed without any problems and is connected to the operation control mechanism of the applicator to check the operation of the head using electrical signals.

Note that even if the label adsorption/holding surface is formed into an arcuate surface as shown in the above embodiments, it can be freely followed and adhered, so if the curvature can be arbitrarily selected, the above-mentioned elasticity can be avoided. Even in a label sticking head having a configuration in which the body is interposed inside the main body, it is not optional to form the front surface of the label holder having a flat suction surface as described in the configuration into an arcuate suction surface. You get it.

In this case, it is preferable to provide an operating means behind the product as it is necessary to automatically swing from side to side according to the object, but if the radius of the curved surface is large, it is not necessary to provide an operating means. In addition, when an operating means is attached, it is desirable that the mounting section be provided with a function of being able to be displaced in all directions.

As shown in the above, according to the present invention, the label application head is freely held against the surface of the article to which the label is applied, and thrust and reaction force are utilized, which makes it difficult to apply the label reliably in the past. Even on uneven surfaces, concave curved surfaces, or convex curved surfaces, labels can be attached accurately without any difficulty, and it can be particularly effective when applied to automatic label attachment. It is.

Note that according to the spirit of the present invention, the present invention is not limited to the above-mentioned embodiments, and modifications within the technical scope of the present invention belong to the present invention.
