  However, the label sticking apparatus for sticking in Patent Document 1 has two conveyors, an introduction conveyor and a transport conveyor, and the two conveyors are stopped and the direction perpendicular to the transport direction in the sticking area between the two conveyors. In addition, the both ends of the band are gripped by the sticking arm that moves in the vertical direction, and are attached to the side surface of the container. For this reason, the conveyor must be divided into two parts, and the structure is complicated, and the container stops moving when the side surface of the container is scooped with a sticking arm, so the processing speed per unit time is limited. There is a problem that there is.

  On the other hand, if it is going to stick a strip with the sticking arm while the container is being transported, the container moves in the transport direction when sticking to the container with the sticking arm, so it is difficult to stick the strip straight.

  This invention is made | formed in view of this point, The place made into the objective is to stick a strip | belt-shaped label to a container reliably, without distorting.

  In order to achieve the above object, in the present invention, a belt-like label is affixed to the side of the container while the pair of arms are advanced at the same speed as the container.

  Specifically, the first invention presupposes a label sticking device that sticks a band-like label on both sides of the container across the lid from above the container having a lid at the upper end.

  According to the above configuration, the label pressing mechanism moves up and down while moving in the transport direction and sticks the strip-shaped label. Therefore, the label pressing mechanism is not distorted compared to the case where the label pressing mechanism does not move in the transport direction. Can be securely attached to the side.

In the second invention, in the first invention,
The transport mechanism includes an upper press conveyor that contacts the lid portion of the container that travels on the transport mechanism at the transport speed and presses it while proceeding at the transport speed.

  According to said structure, since a container is conveyed, pressing the lid part of a container, a container does not incline when pressing with a pair of arm part. Further, a band-like label can be added to the lid.

Further, in the third invention, on the premise of a label sticking method of sticking a band-like label on both sides of the container across the lid from above the container having a lid at the upper end,
This method

The label sticking device 1 is controlled by the control unit 40, and sticks the strip-like label L to both side surfaces C2 of the container C across the lid C1 from above the container C having the lid C1 at the upper end. For example, the label L has both ends L1 formed wide, and the expiry date and the like are described in addition to product information such as fruits and sweets contained in the container C in the wide portion. . In the middle part of the label L, the product name in the container C is described. For example, although the adhesive is provided on the entire back surface of the label L, this adhesive may be provided only at both ends L1 and the central portion.
The label L serves not only to display product information but also to prevent the lid C1 from being removed from the container C. For this reason, both side surfaces C2 of the strip-shaped label L need to be firmly attached to both side surfaces C2 of the container C. The shape of the container C is not particularly limited, but is a circular cross section, an oval shape, an oval shape, a rectangular shape, and the like, and the material thereof is not particularly limited, such as a resin molded product, a metal molded product, and paper. The lid C1 is softer than the side C2 of the container C in order to facilitate removal, and can be removed. In some cases, a thin sheet may be welded or bonded.

  On the upper surface of the base 2, there is provided a transport mechanism 10 that feeds the container C onto the transport path at a predetermined transport speed. The transport path is set on the transport conveyor 11 of the transport mechanism 10.

The separation cylinder 13 is made of an air cylinder, for example, and is supplied with high-pressure air from a compressor (not shown). Then, the container C is detected by the separation sensor 14 provided on the upstream side, and the control unit 40 that receives the signal controls the separation cylinder 13 to control the container 13 so that the containers C are spaced at appropriate intervals (for example, 60 pieces per minute). Is fed onto the conveyor 11.

  Further, a label supply mechanism 20 is provided above the transport mechanism 10 on the upstream side. The label supply mechanism 20 is controlled by the labeler control panel 41 of the control unit 40 and serves to affix the strip-shaped label L to the lid C1 of the container C that is being transported on the transport mechanism 10. The label supply mechanism 20 has a thermal printer 21, and a label roll 22 is detachably and rotatably provided. A number of strip-shaped labels L are affixed to the sheet of the label roll 22 so that the width direction is the transport direction. A printer operation panel 42 is connected to the control unit 40 so that the expiration date and time can be input. The date can be printed on the belt-like label L by the thermal printer 21. If printing such as date is not necessary, the thermal printer 21 and the printer operation panel 42 may be omitted. The label L printed with the date and the like is detected by the label sticking sensor 23 provided in the transport mechanism 10 and the container C is transported, and the center of the label L is pressed against the lid C1 by the sticking part 24 at the tip. It is configured to be attached. At this stage, both ends L1 of the label L are not attached to both side surfaces C2 of the container C. The label supply mechanism 20 includes a labeler position adjustment unit 25, and the label supply mechanism 20 can adjust the vertical and front / rear positions by operating the labeler handle 26.

  On the further downstream side of the label supply mechanism 20, a label pressing mechanism 30 that is controlled by the control unit 40 and presses both ends L 1 of the strip-shaped label L against both side surfaces C 2 of the container C on the transport mechanism 10 while moving up and down. Is provided. As shown in FIG. 1, the label pressing mechanism 30 includes a pair of elevating parts 31 that elevate up and down on both sides of the conveyance path. The pair of elevating units 31 may be moved up and down simultaneously by, for example, an electric motor. The label pressing mechanism 30 includes a pair of arm portions 32 that are rotatably connected to the pair of elevating portions 31 and press the belt-like label L toward the side surface C2 of the container C at the tip. The pair of arm portions 32 are urged so as to approach each other, for example, by a tension coil spring 37 having one end connected to the elevating portion 31. A pressing roller 33 is rotatably provided at the distal ends of the pair of arm portions 32. For the pressing roller 33, a material having appropriate hardness and flexibility such as a resin molded product and an elastomer is suitable. At the lower end of the label supply mechanism 20, a pair of rail portions 34 are provided that guide the rotation operation of the pair of arm portions 32 at a predetermined interval in a direction perpendicular to the transport direction. A tip surface of the pair of rail portions 34 is formed with an inclined surface 34a that is inclined so as to approach each other downward. The pressing roller 33 also serves as a guide roller guided by the rail portion 34. Since the guide roller also serves as the pressing roller 33, it is not necessary to provide a separate guide roller, and the number of parts can be reduced. The pressing roller 33 of the arm portion 32 comes into contact with and is guided by the inclined surface 34a. The side surface C2 of the container C is pressed while the pressing roller 33 at the tip of the pair of arm portions 32 is further lowered from the lower ends of the pair of rail portions 34.

  The label pressing mechanism 30 includes a lateral movement motor 35 that is controlled by the control unit 40. The lateral movement motor 35 is constituted by, for example, a servo motor, and a ball screw (not shown) is advanced and retracted by this servo motor. This is easier to control and maintain than a unitized electric cylinder. Further, a bending sensor 36 is provided at a predetermined position of the transport mechanism 10. The label pressing mechanism 30 is configured to be horizontally movable in the transport direction by sending a detection signal from the bending sensor 36 to the control unit 40 and driving the lateral movement motor 35. The label pressing mechanism 30 is configured to affix the strip-shaped label L to the container C while proceeding at the same speed as the transport speed of the transport mechanism 10 under the control of the control unit 40.

  The label pressing mechanism 30 can adjust the lower end position of the rail portion 34 with the vertical pressing position adjusting handle 38 shown in FIG. Moreover, the space | interval of a pair of rail part 34 can be adjusted with the handle | steering-wheel 39 for the horizontal direction pressing position shown in FIG.

  Between the label pressing mechanism 30 and the transport mechanism 10, there is provided an upper press conveyor 50 that contacts the lid C1 of the container C that travels on the transport mechanism 10 at the transport speed and presses it while proceeding at the same transport speed. Yes. The upper presser conveyor 50 includes an upper presser belt 51 containing a soft material such as sponge. The upper presser conveyor 50 includes an upper presser belt vertical position adjusting handle 52 that can adjust the vertical position thereof according to the height of the container C. The speed of the upper presser belt 51 is controlled by the control unit 40 to the same speed as that of the transport conveyor 11.

  A further presser mechanism 60 is provided on the downstream side of the label pressing mechanism 30. Then, when the increase sensor 61 provided at a predetermined position of the transport mechanism 10 detects that the container C with the label L attached to the both side surfaces C2 is transported by the label pressing mechanism 30, the booster 62 The container C is sandwiched from both sides so that the label L is securely attached to the container C. The push-in mechanism 60 may be omitted.

  An outlet side belt conveyor 70 is provided further downstream of the push-in mechanism 60, and the container C to which the label L is attached is conveyed downstream by the outlet side belt conveyor 70. ing.

  The label pressing mechanism 30, the upper pressing conveyor 50, the pressing mechanism 60, and the like are covered with a protective cover 5 indicated by a two-dot chain line for safety.

  Next, the operation of the label sticking device 1 according to this embodiment will be described.

  First, necessary items such as a date are input on the printer operation panel 42. By operating the control unit 40 or the like, the labeling apparatus 1 and the compressor are turned on, and the transporting mechanism 11 drives the transporting conveyor 11 at a predetermined speed.

  In the upstream process, the container C in which the contents are accommodated and the lid C1 is fitted is supplied to the connecting plate 12.

  Next, when the separation sensor 14 detects the container C, the control unit 40 extends the separation cylinder 13 so that the container C is supplied onto the transport conveyor 11 at a predetermined interval, thereby damming the container C.

  Then, after a certain time, the separation cylinder 13 is opened, and the container C moves on the conveyor 11 at a predetermined speed.

  Next, when the label sticking sensor 23 detects the container C, the control unit 40 and the labeler control panel 41 control the label supply mechanism 20, and the sticking part 24 sticks the label L to the lid part C1. At this time, the label L is attached only to the lid C1.

  Next, the container C enters the area of the upper presser conveyor 50 and moves on the transport conveyor 11 while the lid C1 is pressed by the upper presser belt 51. At this time, the label L attached to the lid C1 is pushed up by the upper pressing belt 51.

  Next, when the bending sensor 36 detects the container C, the controller 40 lowers the elevating unit 31 while moving the entire label pressing mechanism 30 along the transport direction by the lateral movement motor 35, and the pressing roller 33. Is guided by the rail portion 34.

  Next, when the pair of pressing rollers 33 reach the inclined surface 34a, the arm portion 32 rotates so as to approach each other. At this time, since the pair of pressing rollers 33 that also serve as guide rollers are guided by the tips of the pair of rail portions 34 to restrict the movement of the arm portion 32, a belt-like shape is formed on the side surface C2 of the container C while avoiding the lid portion C1. Easy to apply label L.

  Next, the pair of arm portions 32 is pulled by the pulling coil spring 37 from the vicinity of the pressing roller 33 beyond the lid portion C1 and rotated to press both side surfaces C2 of the container C. At this time, since the label pressing mechanism 30 moves in the transport direction, the strip-shaped label L is pasted. Therefore, the strip-shaped label L is pasted on the side surface C2 of the container C without being distorted compared to the case where the label pressing mechanism 30 does not move. Can do. Since the lid C1 of the container C is conveyed while being pressed by the upper pressing belt 51, the container C does not tilt when the label L is pressed by the pair of arm parts 32.

  When the pasting is completed, the control unit 40 moves the label pressing mechanism 30 to the opposite side to the transport position by moving the horizontal movement motor 35 in the reverse direction while raising the elevating unit 31 to return it to the original position.

  Next, when the container C further advances and the increase sensor 61 detects, the control unit 40 drives the increase mechanism 60 and presses both side surfaces C2 of the container C by the increase unit 62. Thereby, both ends L1 of the label L are reliably affixed on the both side surfaces C2 of the container C.

  These steps are performed continuously for each container C.

  In this way, the pair of arm portions 32 moves up and down in accordance with the movement of the pair of lifting portions 31 and rotates when the pair of arm portions 32 descends below the pair of rail portions 34 to move the side surface C2 of the container C from both sides. In the region where the rail portion 34 is present, the belt-like label L is lowered so as to reduce the distance between the ends of the pair of arm portions 32 after descending over the lid portion C1 while avoiding the lid portion C1. Can be pressed down.

  When the container C reaches the outlet both side belt conveyor 70, the container C is conveyed downstream so as to hold both side surfaces C2.

  Therefore, according to the label sticking device 1 according to the present embodiment, the pair of arm portions 32 that can be moved up and down and turn at the same speed as the transport speed of the container C, and the lid portion on the side C2 of the container C on the transport path. Since both ends L1 of the label L affixed to C1 are pressed against both side surfaces C2 of the container C, the belt-like label L can be reliably affixed to the container C without distortion.

3 and 4 show a label pressing mechanism 130 of the label sticking device 1 according to the second embodiment of the present invention, which is different from the first embodiment in that the configuration of the guide roller 133 is different. In the present embodiment, the same parts as those in FIGS. 1 and 2 are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the present embodiment, a guide roller 133 is provided in the middle of the pair of arm portions 132, and the pair of guide rollers 133 are guided by the rail portion 34.

  That is, as illustrated in FIG. 3, when the guide roller 133 moves downward while rotating on the pair of rail portions 34, the pressing roller 33 may or may not contact the rail portion 34. Also good.

  When reaching the inclined surface 34 a at the lower end of the rail portion 34, the guide roller 133 is guided by the inclined surface 34 a and moves so that the pair of arm portions 132 urged by the tension coil spring 37 approach each other.

  Then, the pressing roller 33 at the tip avoids contact with the lid C1, and then comes into contact with both side surfaces C2 of the container C to securely press both side surfaces C2 of the label L.

  Even after the descent is completed, the guide roller 133 abuts against the inclined surface 34a and rises while the rails 34 are raised while re-raising.

  As described above, this embodiment is more advantageous than the first embodiment when the track of the pressing roller 33 is easier to operate and the edge of the lid C1 is protruding.

  In addition, the above embodiment is an essentially preferable illustration, Comprising: It does not intend restrict | limiting the range of this invention, its application thing, or a use.

  For example, in each of the above embodiments, one label L is attached to one container C at a time, but a plurality of labels L may be attached to a plurality of containers C at one time. In that case, a plurality of pairs of arm portions and rail portions may be provided.
