Description

The present invention relates to a sticker application device that applies stickers to objects such as compacts.

Conventionally, there is known a loading device that automatically loads contents by conveying a pallet holding containers such as compacts along a predetermined direction to manufacture a final product. For example, an automatic assembly device described in Patent Document 1 includes a container lid opening device that automatically opens the lid of a compact, a labeling device (sealing device) that affixes a label (seal) indicating a list price, a lot number, etc. to a compact (object), an inner tray installation device that assembles an inner tray filled with cosmetics into a compact, a film placement device that places a film on the cosmetics filled in the inner tray, and a cartoning device that packages the compact. Then, a pallet holding the compact is conveyed to these devices to manufacture a final product.
Here, in the automatic assembly apparatus described in Patent Document 1, the label application device includes a label feeder that feeds a strip-shaped label mount, and a label cylinder device that peels the label off the label mount, receives the label, and applies it compactly.

Japanese Patent Application Publication No. 6-729

However, the label application device described in Patent Document 1 uses a strip-shaped label mount wound in a roll, and as the number of turns of the label mount is reduced by feeding the label mount and applying the labels, the label will warp in line with the winding of the label mount, and the label application device will not be able to properly apply the labels compactly.

The object of the present invention is to provide a sticker application device that can prevent sticker warping and properly apply stickers to objects.

The seal application device of the present invention comprises a seal feed-out means for peeling off a plurality of seals affixed to a backing paper wound into a roll from the backing paper and feeding them out in a predetermined direction, a seal base having a planar mounting surface on which the seal fed out by the seal feed-out means is placed, and a seal gripping means for gripping the seal placed on the seal base and attaching the seal to a predetermined object, the seal base being arranged at a predetermined distance from the mounting surface and comprising a pressing member having an abutment portion that abuts against the seal fed out by the seal feed-out means to prevent warping of the seal, the pressing member comprising a pressing plate that is inclined downwardly towards the seal base in a direction perpendicular to the feeding direction , the pressing plate having a notch formed on the seal feed-out means side of the abutment portion, and the distance between the abutment portion of the pressing member and the mounting surface of the seal base is set so that the distance is narrower on the side opposite the seal feed-out means than on the seal feed-out means side due to the inclination of the pressing plate and the notch.

With this configuration, the sticker application device is equipped with a sticker base having a planar mounting surface on which the sticker dispensed by the sticker dispensing means is placed, and the sticker base is arranged at a predetermined distance from the mounting surface and is equipped with a pressing member having a contact portion that abuts against the sticker dispensed by the sticker dispensing means to prevent the sticker from warping, thereby suppressing warping of the sticker and enabling the sticker to be normally affixed to the object.
In addition, the distance between the abutment portion of the pressing member and the mounting surface of the seal base is set by the inclination of the pressing plate and the cutout portion so that it is narrower on the side opposite the seal dispensing means than on the seal dispensing means side, so that the seal dispensing means can smoothly dispense a seal between the abutment portion of the pressing member and the mounting surface of the seal base.

The present invention preferably includes a posture detection means for detecting the posture of a sticker placed on the sticker base, and a control means for controlling the entire sticker application device, and the control means preferably causes the sticker gripping means to grip the sticker placed on the sticker base based on the posture of the sticker detected by the posture detection means.

With this configuration, the pressing member can prevent the seal from warping, so the posture detection means can reliably detect the posture of the seal placed on the seal base. Then, the control means causes the seal gripping means to grip the seal placed on the seal base based on the posture of the seal detected by the posture detection means, so the seal gripping means can reliably grip the seal placed on the seal base.

In the present invention, it is preferable that the contact portion of the pressing member contacts the outer edge of the seal to prevent the seal from warping.

With this configuration, the abutment portion of the pressing member abuts against the outer edge of the seal to prevent the seal from warping, so that the seal gripping means is less likely to be hindered by the pressing member when gripping a seal placed on the seal base. Therefore, the seal gripping means can reliably grip the seal placed on the seal base.

In the present invention, when the seal is gripped by the seal gripping means, the pressing member is preferably pressed by the seal gripping means to move along the mounting surface of the seal base, thereby releasing the state in which the seal is prevented from warping.

With this configuration, when the seal gripping means grips a seal, the pressing member is pressed by the seal gripping means to move along the mounting surface of the seal base, releasing the state in which the seal was prevented from warping. Therefore, when the seal gripping means grips a seal placed on the seal base, its movement is less likely to be hindered by the pressing member. Therefore, the seal gripping means can reliably grip the seal placed on the seal base.

The container transfer device 5 transfers the containers 20 being transported in the +X-axis direction via the transport path 41 to the pallet 2. Specifically, the container transfer device 5 transfers six containers 20 to the pallet 2.
After the label is affixed to the container 20 by the label application device 4 and before it is transferred to the pallet 2 by the container transfer device 5, in other words, when it is being transported in the +X-axis direction via the transport path 41, the container 20 is inverted so that the container body 201 in the closed state is facing vertically downward and the lid member 202 is facing vertically upward.

The container lid opening device 6 releases the engagement of the hook portion 204 of the container 20 supplied to the pallet 2 and then opens the container 20 by rotating the hinge portion 203 .
The inner plate cleaning device 7 has an index 71 that holds the inner plate D from the vertically upper side, and an index 72 that holds the inner plate D from the vertically lower side, and cleans six surfaces of the inner plate D held by the indexes 71 and 72, including the bottom surface, each side surface, and the peripheral edge of the top surface.

The inner plate loading device 8 loads the inner plate D cleaned by the inner plate cleaning device 7 into each of the containers 20 whose lids have been opened by the container lid opening device 6. Specifically, the inner plate loading device 8 applies hot melt adhesive to the storage portion 201A of the container 20, and then loads the inner plate D filled with the cosmetic C1.
The brush loading device 9 includes a mounting table 91 on which the brush B is placed, and a loading mechanism 92 that loads the brush B placed on the mounting table 91 into the container 20. The loading mechanism 92 loads the brush B into each of the containers 20 in which the inner plate D has been loaded by the inner plate loading device 8. Specifically, the brush loading device 9 loads the brush B into the storage portion 201B of the container 20.

The pallet adjustment device 10 adjusts the pallet 2 to match the size of the container 20. Here, the pallet 2 is capable of storing six containers 20, and the storage width is adjustable. The pallet adjustment device 10 adjusts the storage width of the pallet 2.
The container discharge device 11 includes a discharge path 111 for discharging the container 20, and a transfer mechanism 112 for transferring the container 20 from the pallet 2 to the discharge path 111, and the transfer mechanism 112 transfers the container 20 from the pallet 2 to the discharge path 111 and discharges it.

The detailed configuration of the label application device 4 of the present invention is described below.

4 and 5 are perspective and top views of the label sticking device according to an embodiment of the present invention.
As described above, the label application device 4 includes a transport path 41 that transports the container 20 in the -Y axis direction, and an application mechanism 42 that applies a label to the container 20 transported on the transport path 41 from vertically above.
As shown in Figures 4 and 5, the application mechanism 42 includes a label feed means 43 as a seal feed means arranged on the +X-axis direction side of the conveying path 41, a stage 44 as a seal base arranged between the conveying path 41 and the label feed means 43, and a robot arm 45 as a seal gripping means arranged on the +Y-axis direction side of the label feed means 43 and the stage 44.

The label unwinding means 43 peels off the labels L, which are in the form of a plurality of stickers attached to a backing sheet S wound in a roll, from the backing sheet S and unwinds the labels L in a predetermined direction.
This label unwinding means 43 comprises a first support shaft 431 that rotatably supports the roll shaft SR1 of the roll body SR on which the backing paper S is wound in a roll shape, a rectangular plate 432 arranged adjacent to the stage 44 on the +X axis direction side of the stage 44, a second support shaft 433 that supports the roll shaft SR2 that winds up the backing paper S wrapped around the plate 432, a motor 434 (see Figure 5) that rotates and drives the second support shaft 433 in the direction in which the backing paper S is wound up, and rollers 435A, 435B that are arranged on the upper and lower sides of the plate 432 to wrap the backing paper S around the plate 432.
The label feeding means 43 also includes a first support shaft 431, a plate 432, a second support shaft 433, a motor 434, and a base 436 on which rollers 435A and 435B are attached.

The stage 44 has a flat mounting surface 441. The label L fed by the label feeding means 43 is placed on this mounting surface 441 with the adhesive surface of the label L facing vertically downward. The mounting surface 441 is surface-treated so that the label L can be easily peeled off when placed on the mounting surface 441.
In addition, the stage 44 is arranged at a predetermined distance from the mounting surface 441, and is equipped with a pressing member 46 having a contact portion 461A that abuts against the label L fed by the label feeding means 43 to prevent the label L from warping.

Fig. 6 is an enlarged top view of a main part of the labeling device. Fig. 7 is an enlarged view of the vicinity of the pressing member. Specifically, Fig. 7(A) is a view of the vicinity of the pressing member from above, and Fig. 7(B) is a view of the vicinity of the pressing member from a side (+Y-axis direction).
As shown in Figures 6 and 7, the pressing member 46 includes a pressing plate 461 having an abutment portion 461A, a support plate 462 extending along the X-axis and supporting the pressing plate 461, a base 463 that is approximately L-shaped in a plan view and has a rotation axis 463A that supports the support plate 462 so that it can rotate freely around the Z-axis, and a spring 464 that is attached to the support plate 462 and the base 463 and urges the support plate 462 toward the +Y-axis direction.

Here, the pressing plate 461 of the pressing member 46 is supported by the support plate 462 at an incline so as to descend toward the stage 44 side (see FIG. 4). The pressing plate 461 also has a notch 461B formed on the +X-axis direction side of the abutting portion 461A.
Furthermore, due to the inclination of the pressing plate 461 and the cutout portion 461B, the distance between the abutment portion 461A of the pressing member 46 and the mounting surface 441 of the stage 44 is set to be narrower on the side opposite the label feeding means 43 (-X axis direction side) than on the label feeding means 43 side (+X axis direction side) (see Figure 7 (B)).

The robot arm 45 grasps the label L placed on the stage 44 and attaches the label L to the container body 201 as a predetermined object.
4 to 6, the robot arm 45 includes a rectangular plate-shaped pad 451 that adsorbs the label L, a robot body 452 that moves the pad 451 in three axial directions, namely, X, Y, and Z, and a connection shaft 453 (see FIG. 4) that connects the pad 451 and the robot body 452 so as to be rotatable about an axis perpendicular to the plate surface of the pad 451. Therefore, the robot arm 45 can move the pad 451 in three axial directions, namely, X, Y, and Z. In addition, the robot arm 45 can rotate the pad 451 about an axis perpendicular to the plate surface of the pad 451 by rotating the connection shaft 453.
4 and 5 show the robot arm 45 in an operating state, and FIG. 6 shows the robot arm 45 in an initial state.

FIG. 8 is a block diagram showing the functions of the label attachment device.
The label application device 4 includes the above-mentioned transport path 41 and application mechanism 42, and further includes a position detection means 47 and a control means 48, as shown in FIG.
The posture detection means 47 detects the posture of the label L placed on the stage 44. Specifically, in this embodiment, the posture detection means 47 is a CCD (Charge-Coupled Device) camera, and detects the posture of the label L placed on the stage 44 by capturing an image of the entire label L, including character information printed on the surface of the label L placed on the placement surface 441 of the stage 44.

The control means 48 is configured with a CPU (Central Processing Unit), memory, etc., and executes information processing according to a predetermined program stored in the memory. The control means 48 includes a label control unit 481, a posture detection control unit 482, and an arm control unit 483.

The label control unit 481 drives the motor 434 of the label feeding means 43 to peel off the labels L, which are multiple stickers attached to the backing paper S wound in a roll, from the backing paper S and feeds them along a predetermined direction.
The posture detection control unit 482 detects the position and posture of the label L placed on the stage 44 by having the posture detection means 47 capture an image of the entire label L, including the text information printed on the surface of the label L placed on the mounting surface 441 of the stage 44.

The arm control unit 483 causes the robot arm 45 to grip the label L placed on the stage 44 based on the position and orientation of the label L detected by the orientation detection means 47 .
In addition, the arm control unit 483 attaches the label L held by the robot arm 45 to the container body 201.

FIG. 9 is a flowchart showing the label pasting process executed by the label pasting device.
When the label sticking device 4 sticks a label on the container body 201, the control means 48 executes steps ST1 to ST4 as shown in FIG. 9 in accordance with a predetermined program stored in the memory.
Details of steps ST1 to ST4 will be described below with reference to the drawings.

FIG. 10 is a diagram showing a state in which the label is peeled off from the backing paper by the label feeding means and is fed in a predetermined direction.
First, the label control unit 481 drives the motor 434 of the label feeding means 43 to peel off multiple labels L affixed to the backing paper S wound in a roll from the backing paper S and feed them toward the -X-axis direction, as shown by the arrow in Figure 10 (ST1: label feeding step).

11A and 11B are diagrams showing the state immediately before the label is fed out by the label feeding means, specifically, Fig. 11A is a diagram showing the vicinity of the pressing member from above, and Fig. 11B is a diagram showing the vicinity of the pressing member from a side (+Y-axis direction) side.
When the label L is peeled off from the backing paper S by the label feeding means 43 and fed in the -X-axis direction, since the backing paper S is wound in a roll, as shown in Figure 11, a warp may occur in the label L along the winding of the backing paper S due to a reduction in the number of turns caused by feeding the backing paper S and attaching the label L (see Figure 11 (B)).

12A and 12B are diagrams showing the state immediately after the label is fed out by the label feeding means, in which Fig. 12A is a diagram showing the vicinity of the pressing member from above, and Fig. 12B is a diagram showing the vicinity of the pressing member from a side (+Y-axis direction) side.
In contrast, the stage 44 is positioned at a predetermined distance from the mounting surface 441, and is equipped with a pressing member 46 having an abutment portion 461A that abuts against the label L fed by the label feeding means 43 to suppress warping of the label L, so that warping of the label L can be suppressed as shown in Figure 12 (see Figure 12 (B)).
In addition, the contact portion 461A of the pressing member 46 contacts the outer edge of the label L to prevent the label L from warping (see FIG. 12A).

After peeling the label L from the backing sheet S and unrolling it in the -X-axis direction, the attitude detection control unit 482 detects the position and attitude of the label L placed on the stage 44 by having the attitude detection means 47 capture an image of the entire label L, including the text information printed on the surface of the label L placed on the placement surface 441 of the stage 44 (ST2: label attitude detection step).

FIG. 13 is a diagram showing a state in which the label placed on the stage is gripped by the robot arm.
13, the arm control unit 483 causes the robot arm 45 to grip the label L placed on the stage 44 based on the position and orientation of the label L detected by the orientation detection means 47 (ST3: label gripping step). Specifically, the arm control unit 483 drives the robot arm 45 to move and rotate the pad 451 in accordance with the position and orientation of the label L detected by the orientation detection means 47 (see the arrow in FIG. 13), and then adsorbs the label L to the pad 451, thereby causing the robot arm 45 to grip the label L placed on the stage 44.

Fig. 14 is an enlarged view showing a state in which a label placed on a stage is gripped by a robot arm. Specifically, Fig. 14(A) is a view of the vicinity of the pressing member as seen from above, and Fig. 14(B) is a view of the vicinity of the pressing member as seen from the side (+Y-axis direction).
When the robot arm 45 grips the label L, the pressing member 46 is pressed by the pad 451 of the robot arm 45, and rotates around the rotation axis 463A, as shown in Fig. 14. Specifically, the pressing plate 461 of the pressing member 46 moves in the -Y axis direction along the mounting surface 441 of the stage 44, and releases the state in which the warp of the label L is suppressed (see the arrow in Fig. 14(A)).

FIG. 15 is a diagram showing a state in which a label held by a robot arm is attached to a container body.
15, the arm control unit 483 attaches the label L held by the robot arm 45 to the container body 201 (ST4: label attachment step). Specifically, when attaching the label L held by the robot arm 45 to the container body 201, the arm control unit 483 detects information related to the position and posture of the container 20 being transported on the transport path 41 using a CCD camera (not shown), and based on this detected information, drives the robot arm 45 to move and rotate the pad 451 in accordance with the position and posture of the container body 201 detected by the CCD camera (see the arrow in FIG. 15), and then releases the state in which the pad 451 adsorbs the label L, thereby attaching the label L to a predetermined position on the container body 201.

According to this embodiment, the following actions and effects can be achieved.
(1) The label application device 4 is provided with a stage 44 having a flat mounting surface 441 on which the label L fed out by the label feeding means 43 is placed. The stage 44 is arranged at a predetermined distance from the mounting surface 441 and is provided with a pressing member 46 having an abutment portion 461A that abuts against the label L fed out by the label feeding means 43 to prevent warping of the label L. Therefore, warping of the label L can be suppressed and the label L can be normally affixed to the container body 201.

(2) Since the pressing member 46 can prevent the warping of the label L, the orientation detection means 47 can reliably detect the orientation of the label L placed on the stage 44. Then, the control means 48 causes the robot arm 45 to grip the label L placed on the stage 44 based on the orientation of the label L detected by the orientation detection means 47, so that the robot arm 45 can reliably grip the label L placed on the stage 44.
(3) Since the contact portion 461A of the pressing member 46 contacts the outer edge of the label L to prevent the label L from warping, when the robot arm 45 grasps the label L placed on the stage 44, the movement of the robot arm 45 is less likely to be hindered by the pressing member 46. Therefore, the robot arm 45 can reliably grasp the label L placed on the stage 44.

(4) When the robot arm 45 grips the label L, the pressing member 46 is pressed by the robot arm 45 to move along the mounting surface 441 of the stage 44 and release the state in which the pressing member 46 has held down the warp of the label L. Therefore, when the robot arm 45 grips the label L placed on the stage 44, its movement is less likely to be hindered by the pressing member 46. Therefore, the robot arm 45 can reliably grip the label L placed on the stage 44.
(5) The distance between the abutment portion 461A of the pressing member 46 and the mounting surface 441 of the stage 44 is set so as to be narrower on the side opposite the label feeding means 43 than on the side of the label feeding means 43, so that the label feeding means 43 can smoothly feed the label L between the abutment portion 461A of the pressing member 46 and the mounting surface 441 of the stage 44.

The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of the present invention that can achieve the object of the present invention are included in the present invention.
For example, in the above embodiment, the label sticking device 4 is used in the compact loading device 1, but the seal sticking device of the present invention may be used in other devices.
In the above embodiment, the label application device 4 includes the position detection means 47 for detecting the position of the label L placed on the stage 44 . However, the position detection means 47 may not be included.
In addition, in the above embodiment, the contact portion 461A of the pressing member 46 prevents warping of the label L by contacting one point on the outer edge of the label L, but it may prevent warping of the label L by contacting other points or multiple points. In short, it is sufficient that the pressing member is disposed at a predetermined distance from the placement surface and has a contact portion that prevents warping of the sticker by contacting the sticker fed by the sticker feeding means.

In addition, in the above embodiment, when the robot arm 45 grasps the label L, the pressing member 46 is pressed by the robot arm 45 to move along the mounting surface 441 of the stage 44, thereby releasing the state in which the label L was pressed against the warp. However, in cases where the operation of the robot arm 45 is not hindered by the pressing member 46, the pressing member 46 may not release the state in which the label L was pressed against the warp.

In addition, in the above embodiment, the distance between the abutment portion 461A of the pressing member 46 and the mounting surface 441 of the stage 44 was set to be narrower on the side opposite the label feeding means 43 than on the side of the label feeding means 43, but it may be set to be wider, or it may be set to be uniform. In short, it is sufficient that the pressing member is disposed at a predetermined distance from the mounting surface and has an abutment portion that abuts against the seal fed by the seal feeding means to prevent the seal from warping.

As described above, the present invention can be suitably used in sticker application devices that apply stickers to objects such as compacts.
