Description

  The present invention relates to a label sticking method for sticking a label displaying information such as a product to the outer surface of various label adherends including containers and the like, and a label sticking apparatus for sticking the label.

  Generally, containers made of plastic, paper, metal, etc. are filled and packaged with the contents as a product in the container, and on the outer surface of the container body, the name of the product, A label on which various types of information such as brand, manufacturer / seller name, date of manufacture, expiration date, product material composition, etc. are printed and displayed is attached via an adhesive (pressure-sensitive adhesive) or the like.

  When sticking the product label corresponding to the container on the outer surface of each container, there are cases where the container is manually pasted one by one, or a dedicated label sticking device is used. However, it is common to use a dedicated label sticking device from the viewpoint of manufacturing efficiency.

  By the way, a method for sticking a label to a container body using a dedicated label sticking apparatus is performed on a transport line in a manufacturing process of the container body or on a transport line in a content filling and packaging process. A method of temporarily stopping the movement of the container body, which is an attachment, and moving the label held by the suction pad of the label supply sticking means to the sticking position of the container body, and stopping the movement of the container body There is a method of sticking by moving the label held by the suction pad of the label supply sticking means to the sticking position of the container main body while continuously moving it.

  In addition, in the label sticking method using the suction pad of the label supply sticking means, after moving the suction pad holding the label to the position corresponding to the sticking position of the container body that has stopped moving, Corresponding to the method of sticking the label by pressing the suction pad all the way to the outer surface of the stopped container body, and the sticking position of the container body that is continuously moving the suction pad holding the label There is a method in which the label is adhered to the entire surface while the tip of the label of the suction pad is pressed toward the outer surface of the moving container body after being moved to the position where it is moved.

  In the label sticking method, the method of sticking while pressing the suction pad toward the outer surface of the continuously moving container body can stick without stopping the transport movement of the container as the adherend. On the other hand, it is advantageous in sticking efficiency, but on the other hand, air and bubbles are easily entrapped between the outer surface of the container body and the label sticking surface (adhesive surface). Or wrinkles may occur.

  Therefore, as a measure for preventing irregularities and wrinkles from occurring on the label surface, for example, the specification of JP-A-7-187159 and FIGS. 1 and 4 attached to the specification include the outer surface of the container body. In order to prevent air and bubbles from being trapped between the label and the label attachment surface (adhesive surface), an elastic resin pressing body is used to press the label against the container body. And a method and apparatus for adhering to it are described, and Japanese Patent Application Laid-Open No. 2002-362524 does not entrap air or bubbles between the outer surface of the work body and the label adhering surface (adhesive surface). Thus, a device is described in which a pressing roller for pressing the label against the main body of the container is provided at the time of sticking.

The known patent documents are described below.
JP-A-7-187159 JP 2002-362524 A

  In this way, when an adherend such as a container is continuously moved and a label is supplied and adhered to the adherend, air or bubbles are trapped between the adherend and the label. A pressing body and a pressing roller are used so as not to occur, but the label supplied to the adherend is a sharp angle of a web-like release sheet (separator) on which a large number of labels are temporarily attached at equal intervals. The label is peeled intermittently by the guide plate, and the labels are peeled one by one from the acute angle tip of the release sheet that is folded intermittently fed by the acute angle guide plate, and the adhesive surface of the label faces the adherend surface and can be fed out. It is like that.

  Thus, the labels fed out one by one on the surface of the adherend are opposite from the label end (label end) which is first attached to the adherend by the pressing body or the pressing roller. While pressing toward the adherend surface in order up to the label end (label end) on the side, air and air bubbles held between the adherend surface and the label are on the opposite end (label end) It will be evicted from and pasted.

  However, the adherend surface during continuous movement is already in contact with the adherend surface in front of the adherend surface to which the label tip portion adheres, and then the label tip portion is in contact with the adherend surface. Attached to the outer surface of the moving adherend so that the pressing body and the pressing roller are pressed in the order from the label front end to the label end, and are stuck while expelling the air and air bubbles to be held from the label end. In such a case, there is a risk of scratches caused by the pressing body or the pressing roller.

  In addition, the leading edge of the label leading edge where the labels fed out one by one on the adherend surface are first attached to the adherend, for example, rise slightly from the adherend surface and are correctly attached to the adherend surface. If it is not, the pressing body or pressing roller that is already in contact with and pressed against the adherend surface in front of the label leading edge will be caught by the tip of the label leading edge, and the label may be damaged or jammed. There is also a risk of occurrence.

  In addition, while feeding the label by intermittent feeding of the release sheet, in order to supply and stick the label tip to a predetermined sticking position on the adherend surface during continuous movement, the continuous moving speed of the adherend and the label It was difficult to match and adjust the feeding speed.

  The present invention relates to a label sticking method for supplying and sticking a label with an adsorption pad to an outer surface of an adherend such as a container that is continuously moving, and a pressing body and a press for expelling air and bubbles. Avoids the occurrence of scratches on the outer surface of the moving adherend due to the roller, and the risk that the pressing body or the pressing roller gets caught in the slightly raised part of the leading edge of the label leading to breakage of the label or jamming Is to facilitate the matching and adjustment of the continuous moving speed of the adherend and the feeding speed of the label.

  Subsequently, the rotational movement means C provided with the rotating body 14 driven and rotated around the support shaft 14a in the direction of the arrow (leftward) continuously at a constant speed at the rotational peripheral speed w is the first rotation receiving means B. The adherend 1 that is continuously moved in the rotational direction by the rotation of the rotating body 11 while being held by the housing portion 12 and the arcuate guide portion 13 is rotated with the rotating body 11 of the first rotation receiving means B. At the overlap position of the rotating body 14 that overlaps with each other, the rotation of the rotating bodies 11 and 14 and the arcuate guide portion 13 cause the rotation of the rotating body 11 of the first rotation receiving means B from within the accommodating portion 11. One piece is received and accommodated in each of the fixed holding portions 15 provided at a plurality of locations at equal circumferential length intervals d along the rotation outer peripheral end portion of the rotating body 14.

  Then, the rotational movement means C shakes the received adherend 1 by adherend fixing and holding means (not shown) by an air adsorption chucking method or an open / close claw clamp method or the like provided in each fixing and holding portion 15. While being fixed and held so as not to move, the rotating body 14 is moved in the rotating direction by the rotation of the rotating body 14.

  And in the fixed position outside the rotation outer peripheral edge part of the rotary body 14 of the said rotational movement means C, as shown in the top view of FIG. 1, the label supply sticking means F is 1 group, 2 groups or more. The label supply and sticking means F is held by the fixed holding portions 15 of the rotating body 14 of the rotating and moving means C and is rotated and moved. A label is supplied to the outer surface, and the entire surface of the label is adhered to the outer surface of the adherend 1 while air is vented between the outer surface of the adherend 1 and the label attaching surface.

  Subsequently, the second rotation receiving means D including the rotating body 16 driven and rotated around the support shaft 16a in the direction of the arrow (rightward) continuously at a constant speed at the rotational peripheral speed w is the rotational movement means C. The adherend 1 to which the label is attached by being continuously moved in the rotation direction by the rotation of the rotating body 14 while being fixedly held by the fixed holding section 15 of the rotating body 14 and the rotating outer peripheral end of the rotating body 14 is mutually rotated. At the overlap position of the rotating body 16 that overlaps with each other, the rotation of the rotating bodies 14 and 16 and the adherend 1 accommodated in the fixed holding portion 15 are guided along the rotational movement direction of the rotating body 16.

The label-attached adherend 1 that is continuously moved in the rotation direction by the rotation of the rotating body 16 while being held by the accommodating portion 17 and the arcuate guide portion 18 is rotated by the rotating body 16 of the second rotation receiving means D. At the overlap position of the carry-out path 20 that overlaps at the outer peripheral end portion, the rotation of the rotating body 16 and the guide by the arcuate guide portion 18 cause the second rotation receiving means C to move out of the housing portion 17 of the rotating body 16. The adherend 1 received on the carry-out path 20 and having the label attached thereto is sequentially carried out along the carry-out path 20 by the carry-out conveyor 19 at the same or a predetermined speed as the rotational peripheral speed w of the rotary body 16. It is to be taken out.

  The adherend 1 is continuously provided by the adherend carrying-in means A, the first rotation receiving means B, the rotational movement means C, the second rotation receiving means D, and the adherend carrying-out means E in each of the label attaching devices. In each operation of carrying in, continuously rotating, and continuously carrying out, it was provided on the rotating body 14 of the rotary moving means C by the label supply sticking means F arranged outside the rotating outer periphery of the rotary moving means C.

<Label sticking operation by the main body frame F1 rotation type label feeding sticking means F>
The operation of the main body frame F1 rotation type label supply sticking means F will be described below. FIGS.

  As shown in FIG. 2, the suction pad 32 of the label suction pad portion 30 of the label supply sticking means F facing the outside of the rotating outer peripheral end portion of the rotating body 14 of the rotational movement means C is rotated by the rotating body 14. It is held in a posture parallel to the tangential direction of the circle.

Subsequently, before the outer surface (front surface) of the adherend 1 held continuously by the fixed holding portion 15 of the rotating body 14 continuously rotating at the rotational peripheral speed w reaches the position facing the suction pad 32. 3, the peeling plate 45 at the rear end portion of the suction surface 32 b of the suction pad 32 is swung in the forward direction by the support shaft 41, so that the rear end of the suction surface 32 b of the suction pad 32. The distance m between the pressing roll 35 and the front end portion 46 of the peeling plate 45 is set to a distance equal to the length n of the label L by moving in the direction of the arrow to a position that is close to and opposed to a part of the surface of the part. At the same time, the web-like release sheet S corresponding to the length substantially corresponding to the extension movement length of the release plate 45 is wound by the unwinding and winding operation of the unwinding unit 50 and the winding unit 60 (see FIG. 1). Roll web mounted on exit 50 It is unwound from a release sheet S, while, also winding section 60 for winding rotation of the web-like release sheet S of the same length fraction.

  At that time, a web-like shape in which a large number of labels L fed through the V-shaped acute end portion 46 of the peeling plate 45 via a V-shaped turn (in the direction of the arrow) are temporarily attached so as to be peeled at equal intervals. From the release sheet S, the label L has its width direction set to the vertical direction, the posture is straightened by the lumbar force (rigidity) of the label L, and close to the suction surface 32b of the suction pad 32 in close proximity to each other. The label L peeled off from the portion L1 is in a state where the end portion L2 of the label L is still held slightly peeled from the surface of the release sheet S (or the end portion L2 of the label L is completely In the state released from the surface of the release sheet S), the leading end L1 of the label L faces the adherend 1 on the peripheral surface of the pressing roll 35 attached to the suction pad 32 in a fixed state. Air suction reaching the peripheral surface Is sucked and held by air suction operation of the air suction holes 32c (see FIG. 2) on the suction surface 32b of the suction pads 32 are created.

  Subsequently, as shown in FIG. 4, before the outer surface (front surface) of the adherend 1 that continuously rotates and moves reaches the position facing the suction pad 32, the peeling plate 45 is moved backward by the rotation of the support shaft 41. It is moved backward by a swinging motion in the direction to return to the original position.

  Then, as shown in FIG. 4, after the return plate 45 is returned to its original position by swinging and moving backward by the rotation of the support shaft 41 (or by the rotation of the support shaft 41, At the same time when the outer surface (front surface) of the adherend 1 that is held by the fixed holding portion 15 of the rotating body 14 and continuously rotates and reaches the position facing the suction pad 32 at the same time as the start of the backward movement operation. The suction pad 32 rotates in the direction of the arrow (leftward) about the support shaft 31b, and the label is attracted to the suction surface 32b by the air suction operation by the air suction hole 32c (see FIG. 2) of the suction surface 32b. The front end L1 of L is pressed to the sticking position on the outer surface of the adherend 1 by a pressing roll 35 pivotally supported on a bearing arm 34 fixed to the front end of the suction pad 32, and the front end L1 of the label L is pressed. Start sticking The

  At that time, the suction pad 32 is set to −θ with the center line O passing through the rotating shaft 31b as a steady position by the pressing of the pressing roll 35 to the outer surface of the adherend 1 by the elastic rocking pressing mechanism described above. Since it is pivotally supported by the rotating shaft 31b supported by the bearing portion 31a of the rotating portion 31 in a state of being biased by the spring 36c in the angular direction (left rotation direction), it is −θ around the supporting shaft 33. By swinging and moving by an angle, the label L is pressed against the outer surface of the adherend 1 against the spring 36c.

  Further, when a material such as elastic rubber, urethane, or sponge is used for the roll material of the pressing roll 35, the arm 34 supported by the support shaft 33 resists the spring only in the clockwise direction. For the initial pressing (pressing in the counterclockwise rotation direction) in the sticking of the leading end L1 of the label L by the pressing roll 35, the elasticity of the roll material of the pressing roll 35 is applied. You may make it utilize sex.

  Subsequently, the air suction operation by the air suction hole 32c of the suction surface 32b of the suction pad 32 is stopped, the label L is released from the suction surface 32b of the suction pad 32, and is held by the fixed holding portion 15 of the rotating body 14. As shown in FIG. 5, the position of the leading end L1 of the label L adhered to the adherend 1 is moved by the continuous movement of the adherend 1 that continuously rotates, and the pressing roll pressing the label L surface. 35, while pressing the sticking surface (adhesive surface) of the label L against the outer surface of the adherend 1, the label L moves relative to the direction from the front end L1 to the end L2. The entire surface of the label L is adhered to the outer surface of the adherend 1 while the air held between the attachment surface and the outer surface of the adherend 1 is vented toward the label end L2.

  Thereafter, the suction pad 32 subsequently returns to the original position shown in FIG. 2 by the rotation of the support shaft portion 31b that is pivotally supported by the vertical bearing portion 31a of the rotation support portion 31 that attaches and supports the suction pad 32. Then, by repeating the above-described operations shown in FIGS. 2 and 3 to 5, the adherence that is held by each fixed holding portion 15 of the rotating body 14 of the rotary moving means C that is the continuous moving means and is being continuously rotated. The label L is attached to the outer surface of the body 1.

<Label sticking operation by the label supply sticking means F of the body frame F1 fixing method>
The operation of the label supplying and sticking means F of the main body frame F1 fixing method will be described below. FIGS. 2 and 6 to 11 show a fixing method in which the main body frame F1 does not rotate.

  As shown in FIG. 2, the suction pad 32 of the label suction pad portion 30 of the label supply sticking means F facing the outside of the rotating outer peripheral end of the rotary body 14 of the rotational movement means C is rotated by the rotation of the rotary body 14. It is held in a posture parallel to the tangential direction of the circle.

  Subsequently, as shown in FIG. 6, the outer surface (front surface) of the adherend 1 that is held by the fixed holding portion 15 of the rotating body 14 that continuously rotates at the rotational peripheral speed w and continuously rotates is the suction pad 32. Before reaching the facing position, the peeling plate 45 at the rear end portion of the suction surface 32b of the suction pad 32 is partly attached to the rear end portion of the suction surface 32b of the suction pad 32 by the extension operation of the air cylinder 47. The distance m between the pressing roll 35 and the front end portion 46 of the peeling plate 45 is set to a distance equal to the length n of the label L and the unwinding portion 50 (see FIG. 1)), the web-like release sheet S corresponding to the length approximately corresponding to the extension movement length of the release plate 45 is unwound from the roll web-like release sheet S attached to the unwinding portion 50. In the meantime, Preparative portion 60 winding rotation is stopped.

  Subsequently, as shown in the plan view of FIG. 7, before the outer surface (front surface) of the adherend 1 that continuously rotates and moves reaches the position facing the suction pad 32, the unwinding operation of the unwinding unit 50 While unwinding the release sheet S to which the label L is temporarily attached and winding the release sheet S by the winding operation of the winding unit 60, the V-shaped acute angle tip 46 of the release plate 45 is V A label L is formed from a web-like release sheet S on which a large number of labels L fed via a character-shaped turn (in the direction of an arrow) are temporarily attached so as to be peeled at equal intervals, and the width direction of the label L is set to a vertical direction. The label L is peeled while straightly facing the suction surface 32b of the suction pad 32 in parallel with the suction force (rigidity) of the label L, and the peeled label L is separated from the end of the label L. L2 is still slightly peeled off The tip L1 of the label L is adsorbed in a state in which the label L is not peeled off (or the end L2 of the label L is completely peeled from the release sheet S and released). The suction surface of the suction pad 32 that has reached the peripheral surface facing the adherend 1 on the peripheral surface of the pressing roll 35 that is urged and attached to the pad 32 in a swingable manner, and is performing an air suction operation. 32b is sucked and held by the air suction operation of the air suction hole 32c (see FIG. 2).

  Subsequently, as shown in FIG. 8, before the outer surface (front surface) of the adherend 1 that continuously rotates and moves reaches the position facing the suction pad 32, the peeling plate 45 is moved back to the original position by the shortening operation of the air cylinder 47. The label L was peeled off while the unwinding operation of the unwinding portion 50 was stopped while the separation distance between the pressing roll 35 and the acute angle tip 46 of the peeling plate 45 was set to the original distance m. The web-like release sheet S is taken up by the take-up unit 60 via the collection guide roll 43 by the take-up operation of the take-up unit 60 by the length of the backward movement of the release plate 45.

Subsequently, as shown in FIG. 9, at a timing when the outer surface (front surface) of the adherend 1 that is held by the fixed holding portion 15 of the rotating body 14 and continuously rotates moves to a position facing the suction pad 32. The suction pad 32 rotates in the direction of the arrow (leftward) about the support shaft 31b, and the label is attracted to the suction surface 32b by the air suction operation by the air suction hole 32c (see FIG. 2) of the suction surface 32b. The leading end L1 of L is pressed to the sticking position on the outer surface of the adherend 1 by the pressing roll 35 at the leading end of the suction pad 32, and the sticking of the leading end L1 of the label L is started.

  At that time, the pressing roll 35 is pivotally supported by the support shaft 33 in a state where the center line O is urged by a spring in a ± θ angle direction (both left and right rotation directions) with the center line O as a steady position. Thus, the label L is pressed against the outer surface of the adherend 1 against the spring by swinging and moving about the support shaft 33 by an angle of θ1.

  Further, when a material such as elastic rubber, urethane, or sponge is used for the roll material of the pressing roll 35, the arm 34 supported by the support shaft 33 resists the spring only in the clockwise direction. For the initial pressing (pressing in the counterclockwise rotation direction) in the sticking of the leading end L1 of the label L by the pressing roll 35, the elasticity of the roll material of the pressing roll 35 is applied. You may make it utilize sex.

  Subsequently, the air suction operation by the air suction hole 32c of the suction surface 32b of the suction pad 32 is stopped, the label L is released from the suction surface 32b of the suction pad 32, and the rotating body 14 is fixedly held as shown in FIG. By the continuous movement of the adherend 1 that is held by the portion 15 and continuously rotates, the position of the tip L1 of the label L adhered to the adherend 1 is moved and the pressing roll 35 pressing the label L surface. While the pressing surface (adhesive surface) of the label L is pressed against the outer surface of the adherend 1, the label L is moved relatively from the front end L1 to the end L2 of the label L. The label L is adhered to the outer surface of the adherend 1 while the air held between the attachment surface and the outer surface of the adherend 1 is vented toward the label end L2.

The label L is attached to the outer surface of the first.

  At this time, the pressing roll 35 varies depending on the outer surface shape of the adherend 1 (an elliptical arc shape or a true arc shape as shown), but the center line O is positioned at a steady position as shown in FIG. As a result, the arm 34 pivotally supported by the support shaft 33 in a state of being biased by a spring in the + θ angle direction (rightward rotation direction) is swung around the support shaft 33 by an angle of θ2, L is pressed against the outer surface of the adherend 1 against the spring while releasing air.

  Further, as shown in FIG. 11, the support shaft is supported by an arm 34 that is supported by the support shaft 33 in a state in which the center line O is a steady position and is biased by a spring in the angle direction of −θ (left rotation direction). The label L is attached to the outer surface of the adherend 1 while pressing it against the spring against the spring while releasing air.
