Summary of the Invention

Problems to be Solved by the Invention

[0004] Generally, in retail stores such as supermarkets, labels may be affixed to a large number of sheets, the contents may be contained, and they may be arranged at the storefront. The conventional label device has a complicated operation when initially setting it up, and does not sufficiently consider the excess length of the label paper. That is, since it is necessary to ensure a large excess length of the label paper (ensure 550 mm or more), there is a problem of material loss.

[0005] Furthermore, in a labeling device that applies a label to each separated sheet, it is necessary to secure a transport path for the sheets and transport the separated sheets to the labeling device. Therefore, it is necessary to secure a transport path for transporting the sheets, which makes the entire device larger. It is preferable for the labeling device to be miniaturized and capable of efficiently peeling labels from label paper, applying them to sheets, and separating individual sheets.

[0006] The present invention was made based on the above-mentioned problems, and aims to provide a labeling device that allows for easy setting of label paper, does not increase the size of the device, and does not result in material waste of label paper. [Means for solving the problem]

[0007] To achieve the above objective, the label application device according to the present invention has a housing equipped with a label application mechanism that pulls out label paper, on which labels are continuously attached along the longitudinal direction to a strip-shaped backing sheet, from a label roller, picks up labels one by one from the label paper, and applies them to the top sheet of a stacked sheet, the housing having a backing sheet insertion opening into which the backing sheet, which has been pulled out from the label roller and on which labels have been sucked up by the label suction part of the label application mechanism, a pair of rollers that grip and transport the backing sheet inserted from the backing sheet insertion opening, an operating member that switches the pair of rollers between a contact state and a separated state, and the label suction part that is pressed The device comprises a label removal unit that picks up labels from label paper, and a winding roller installed downstream of the roller pair and rotated to wind up the discharged backing paper. The label removal unit has a backing paper insertion opening so that the label paper enters the housing, and is supported to open widely to the housing when setting the label paper, and to open narrowly to the housing when peeling off the label. The winding roller rotates to wind up the backing paper when the roller pair rotates to transport the backing paper to a winding-ready position when setting the label paper.

[0008] In the label application device described above, when setting label paper, a pair of rollers installed inside the housing is moved from a contact state to a separated state by an operating member, the label paper is inserted into the pair of rollers, and the pair of rollers is returned to the contact state. At this time, even if the leading edge of the label paper is not set on the winding roller, the winding roller is rotated when the leading edge of the label paper (backing paper) is transported to the winding position by the driving of the pair of rollers, so the label paper can be easily set. In addition, it is possible to reduce the excess length of the label paper, thereby suppressing material loss. Furthermore, the label removal section that forms the backing paper insertion opening is supported to open widely to the housing when setting the label paper, so the label paper can be easily set. [Effects of the Invention]

[0009] According to the present invention, a label application device can be obtained that allows for easy setting of label paper, does not increase the size of the device, and does not result in any material waste of label paper. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0011] An embodiment of a label application device will be described below with reference to Figures 1 to 5.

[0012] Figure 1 is a perspective view of the label application device of this embodiment as seen from the label application side, Figure 2 is a perspective view of the label application device shown in Figure 1 as seen from the backing paper winding device side, Figure 3 is a side view of the label application device shown in Figure 1, Figure 4 is a diagram showing the label application device and sheet movement mechanism shown in Figure 1, and Figure 5 is a rear view of the label application device shown in Figure 1. In these diagrams, the direction of movement of the stacked sheets (front-to-back direction) is denoted by X, the direction perpendicular to the direction of movement of the sheets (width direction) is denoted by Y, and the direction perpendicular to the XY plane (up-down direction) is denoted by Z.

[0013] The label affixing device 1 according to this embodiment has a mounting table 3 for stacking a large number of storage bags (also referred to as sheets) 100 for storing foods such as vegetables, and a housing 2 provided with a label roller 5 around which a strip of label paper 121 is wound. The label paper 121 has labels 120 with product names etc. printed thereon in advance continuously attached to a strip of backing paper 122 in the longitudinal direction. The mounting table 3 is installed on the lower side of the housing 2, and the label roller 5 is installed on the upper side of the housing 2. The label paper 121 pulled out from the label roller 5 is sent forward and then deflected downward, and the labels 120 are sequentially sucked (peeled off) at the front part of the housing, and are sequentially attached to the uppermost storage bag 100 on the mounting table 3. Then, the backing paper 122 from which the labels 120 have been peeled off is conveyed into the housing through a backing paper insertion port to be described later, and is wound around a winding roller 61 of a backing paper winding device 60.

[0014] In the above-described configuration, the strip of label paper 121 (backing paper 122) is conveyed by the driving of a pair of rollers (roller pair) to be described later disposed inside the housing. That is, the label paper 121 to which the labels 120 are continuously attached is sandwiched at the portion where the roller pair abuts against each other, and is pulled out from the label roller 5 by the driving of one of the driving rollers. Then, the pulled-out label paper is peeled off the labels 120 on the way, and the backing paper 122 is conveyed to the rear side via the inside of the housing 2 by the driving of the roller pair, and is wound around the rotationally driven winding roller 61.

[0015] Note that the label paper 121 pulled out from the label roller 5 is sucked one by one continuously by a suction machine 11 (label suction portion 11A) installed on the front side of the housing 2, and is attached to the uppermost sheet 100a of the stacked sheets 100.

[0016] The sheet 100 stacked on the aforementioned mounting base 3 is constructed as a so-called triangular shape by overlapping rectangular plastic film sheets (nylon storage bags) and welding the outer edges together. The contents such as vegetables and fruits are stored inside. The label 120 attached to it has the product name, price, barcode, etc., pre-printed on it.

[0017] The following describes the setup of label paper 121 and the process of applying the labels. The housing 2 is equipped with a guide roller 8 downstream of the label roller 5, which guides the pulled-out label paper 121 toward the downstream side of the front of the housing 2. A label application mechanism 10 is also installed downstream of the guide roller 8 on the housing 2, and this label application mechanism 10 applies one label to the top sheet 100a of the laminated sheet 100 on the mounting base 3. The front portion of the top sheet 100a with the label attached is then flipped up by a sheet moving mechanism 20 provided on the housing 2 and moved to the rear side of the laminated sheet 100.

[0018] The label application mechanism 10 includes a suction device 11 positioned at the center of the width direction of the transported label paper 121. The label suction part 11A at the tip of the suction device 11 sucks the label 120 from the label paper 121 and attaches it to the top sheet 100a of the laminated sheet 100. Adhesive is applied to the back surface of the label 120. The suction device 11 is driven toward the rear (towards the housing) in synchronization with the transported label paper 121, and the label suction part 11A picks up the label 120 as it peels off from the label paper 121 as it bends and is transported into the housing. That is, as the label 120 bends and is transported (loaded) into the housing, the label 120 peels off from the backing paper due to the bending and is picked up by the label suction part 11A. After that, the suction device 11 is driven to rotate approximately 90°, and the sucked label is pressed against the top sheet 100a to adhere it.

[0019] The suction device 11 is configured as a cylinder that sucks in air, and when air is sucked in by the label suction part 11A at its tip, the label 120 is sucked from the label paper 121. The suction device 11 is supported by a cylinder rotation arm 13 provided on the housing 2. By controlling the rotational drive of this cylinder rotation arm 13 and the air suction operation of the suction device 11, the label 120 is continuously affixed to the top sheet 100a while the device is in operation.

[0020] The housing 2 is equipped with a backing paper insertion opening 15 into which the backing paper (backing paper with the label 120 sucked up by the label suction part 11A of the label application mechanism 10) 122 pulled out from the label roller 5 is inserted (carried in). As described above, the downstream side of this backing paper insertion opening 15 is bent to make it easier to peel off the label, and after the label is peeled off, the backing paper 122 with the label sucked up by the suction device is guided to the roller pair inside the housing 2.

[0021] Furthermore, the housing 2 of this embodiment is equipped with a guide mechanism 30 that guides the label paper 121 (backing paper 122) pulled out from the label roller 5 from the label suction section 11A, through the backing paper insertion opening 15, to the pair of rollers installed inside the housing 2. This guide mechanism 30 has a function that allows the label paper 121 pulled out from the label roller 5 to be easily set, thereby enabling the label paper to be transported in a stable state.

[0022] The guide mechanism 30 includes a press guide 31 that extends in the width direction to press the label paper 121 pulled from the label roller 5 against the front surface of the housing 2. This press guide 31 has the function of pressing the label paper 121, which has been deflected by the guide roller 8, towards the housing to prevent it from bulging. Furthermore, a second press guide 33 with a similar function is provided downstream of the press guide 31 as a guide mechanism.

[0023] The second retaining guide 33 is biased toward the housing 2 by a biasing spring (not shown). By pulling the tensioning operation part 33a forward against the biasing force, a gap is formed between the retaining guide 33 and the housing 2. The label paper is then inserted into this gap, and the tensioning operation part 33a is returned to its original position to perform the initial setup. This prevents the label paper from bulging.

[0024] Downstream of the second pressing guide 33, a label removal section 37 is provided, against which the label suction section 11A is pressed when the label 120 is sucked up. The label removal section 37 is formed in a plate shape, and the backing paper 122 enters the gap between the upper edge of its front surface and the housing 2, guiding the backing paper 122 into the housing (the gap constitutes the backing paper insertion opening 15).

[0025] In this case, the backing paper transport path from the backing paper insertion opening 15 to the following pair of rollers 40 is bent sharply upward from the backing paper insertion opening 15 (bent diagonally upward), so when the label paper 121 enters the housing from the backing paper insertion opening 15, the label paper 121 is bent, causing the label 120 to peel off the backing paper (or to peel off easily).

[0026] In other words, as the label paper 121 is transported downward from the second pressing guide 33, and the backing paper 122 is transported into the housing while bending through the gap at the upper end of the label removal section 37 (backing paper insertion opening 15), the label 120 moves downward while being peeled from the label paper 121 and is picked up by the label suction section 11A.

[0027] Inside the housing 2, a pair of rollers 40 is provided near the cardboard insertion opening 15 to grip and transport the cardboard 122 inserted through the cardboard insertion opening 15. This pair of rollers 40 consists of a drive roller 41 on one side and a driven roller 42 on the other. In this embodiment, the lower roller is the drive roller 41 and the upper roller is the driven roller 42. This pair of rollers 40 can be switched between a contact state and a separation state by an operating member 45.

[0028] In this embodiment, the device is configured to allow switching with a simple operation (one-touch operation). Specifically, the operating member 45 comprises a pair of rotating parts 46a and 46b that are rotatably supported by the housing 2 at both ends of the support shaft of the driven roller 42, and an operating part 46c bridged at the tips of this pair of rotating parts 46a and 46b. The pair of rotating parts 46a and 46b are biased downward (towards the contact side of the roller pair) by a biasing means (not shown). As a result, by lifting the operating part 46c against the biasing force, the roller pair 40 is separated, and by pushing the operating part 46c downward according to the biasing force, the roller pair 40 is brought into contact.

[0029] In this embodiment, the label paper (backing sheet) 121 pulled out from the label roller 5 is transported between the pair of rotating parts 46a and 46b, and the contact / separation operation of the roller pair 40 can be easily performed. Furthermore, as described above, the label paper pulled out from the label roller 5 is guided from the label suction part 11A to the roller pair 40 via the guide mechanism 30 provided in the housing 2.

[0030] Downstream of the roller pair 40, a backing paper winding device 60 is provided for winding up the backing paper 122 that is being transported by the drive of the roller pair 40. The backing paper winding device 60 is equipped with a winding roller 61, which winds up the backing paper that is being transported by the drive of the roller pair 40. In this case, the rotation of the winding roller 61 is controlled in conjunction with the rotational drive of the roller pair 40, and the discharged backing paper 122 is wound onto the winding roller 61 without slack.

[0031] The label 120 has been affixed to the top sheet 100a on the mounting table 3 by the label affixing mechanism 10. The top sheet 100a is then moved to the rear side of the stacked sheets 100 by the sheet moving mechanism 20 provided in the housing 2. The sheet moving mechanism 20 includes a suction device 21 for sucking up the top sheet and a sheet separation mechanism that prevents multiple sheets from being lifted (by scraping them off so that only one sheet remains) when the sheet is lifted by the suction device 21.

[0032] Multiple suction devices 21 are arranged (five in this embodiment) at positions symmetrical with respect to the width direction of the sheet, so as to evenly suction the top sheet 100a to which the label 120 is attached. The suction devices 21 can be appropriately changed depending on the size of the sheet to be separated, and can be modified as appropriate, for example, by arranging one on each side (a total of two).

[0033] The sheet separation mechanism is, for example, located on the edge (front edge) side of the stacked sheets 100 stacked on the mounting base 3, and includes a flange that presses the top sheet of the stacked sheets 100 against the edge within a certain range in a biased state. When the top sheet is sucked up and lifted by the suction machine 21, this flange has the function of preventing the second and subsequent sheets from rising in a chain by bending the sheet and separating it from the flange (a function of scraping off the second and subsequent sheets). Furthermore, the configuration of such a sheet separation mechanism 22 can be modified as appropriate, as long as it can separate from the second and subsequent sheets when the top sheet is moved in the direction in which it is sucked up and lifted.

[0034] The suction device 21 of the sheet moving mechanism 20 is supported by the housing 2 so as to be driven back and forth along the stacked sheets 100, and the top sheet 100a to which the label 120 is attached is moved backward as it is lifted up by the suction of the suction device 21, and the suction is released on the sheet after the top sheet so that it is folded over the next sheet.

[0035] Therefore, on the rear side of the laminated sheet, the sheets with labels attached are sequentially folded over, so the laminated state of the sheets with labels attached does not become longer in the front-to-back direction, making it possible to make the entire device more compact.

[0036] Next, the configuration of the cardboard winding device 60 will be described with reference to Figures 6 to 9. The cardboard winding device 60 is equipped with a winding roller 61 that is rotatably supported by the housing 2 (roller mounting stay 2A). The cardboard discharged from the cardboard discharge section 65 provided in the housing 2 by the roller pair 40 is wound onto the winding roller 61, which is rotationally driven in the direction of the arrow in Figure 8. In this case, the winding roller 61 can be rotationally driven by the same drive source (drive motor) as the roller pair 40, and is connected to the drive source by a gear train, drive belt, etc.

[0037] It is preferable to provide a backing paper passage between the winding roller 61 and the backing paper discharge section 65 to guide the backing paper discharged from the backing paper discharge section 65 toward the winding roller. Such a backing paper passage can be made up of, for example, a pair of flaps 66a and 66b as shown below. That is, a pair of flaps 66a and 66b that swing in the vertical direction are made up of substantially the same shape and are plate-like, and the gap formed between them can form a backing paper passage 66c. The backing paper 122 discharged from the backing paper discharge section 65 enters the backing paper passage 66c, and the backing paper 122 guided there is then conveyed toward the winding roller 61.

[0038] As shown in Figure 7, a flat portion 61a is formed on the outer circumferential surface of the winding roller 61, and a cavity (notch) 61b extending radially is formed in the center of the flat portion 61a. This cavity 61b extends in the axial direction (width direction), and the winding roller 61 is supported by a semi-cylindrical portion 61c with a substantially semicircular cross-section and a semi-cylindrical portion 61d of substantially the same shape, which are separated by the cavity and face each other at a certain distance apart.

[0039] Furthermore, a structure is provided between the semi-cylindrical sections 61c and 61d to deform the winding roller 61 radially and reduce its diameter. This diameter reduction structure is constructed, for example, by supporting a spring 62 in the gap at the ends of the semi-cylindrical sections 61c and 61d. When the semi-cylindrical sections 61c and 61d are pinched and compressed radially, the diameter of the winding roller 61 is reduced. Therefore, when removing the backing paper 122 wound around the winding roller 61, pinching the semi-cylindrical sections 61c and 61d reduces their diameter, making it easy to remove the backing paper 122 while it is wound around the roller.

[0040] Furthermore, the positional relationship between the pair of flaps 66a, 66b and the winding roller 61 is controlled during the initial setup so that the hollow portion 61b of the winding roller 61 is located on the extension of the backing paper passage 66c of the pair of flaps 66a, 66b.

[0041] In this configuration, when the roller pair 40 is driven and the backing paper 122 is discharged, the backing paper 122 enters the cavity 61b of the take-up roller 61, which is in a stopped state. With the backing paper 122 inside, the take-up roller 61 is rotated, and the discharged backing paper 122 is automatically wound up. In this way, when the label paper 121 is set on the label roller 5 and pulled out and held at the position of the roller pair 40, the take-up roller 61 rotates with a delay after the rotation of the roller pair 40, and the backing paper 122 guided through the backing paper passage 66c is automatically wound up in the initial stage.

[0042] In other words, the winding roller 61 rotates when the backing paper 122 is transported to a winding-ready position to wind the backing paper, eliminating the need to grasp the discharged backing paper 122 and wind it onto the winding roller 61 (making operation easier).

[0043] When using the label application device 1 configured as described above, the label paper 121 is mounted on the label roller 5, and the label 120 at the leading edge of the label paper is peeled off from the backing paper (approximately 80 mm in this embodiment). Next, the operating part 46c of the operating member 45 is lifted to separate the roller pair 40. In this state, the label paper 121 is passed through the press guide 31 of the guide mechanism 30, and the tension operating part 33a of the press guide 33 below it is pulled forward against the biasing force, and the label paper 121 is inserted into the gap between the press guide 33 and the housing 2. Next, the backing paper 122 from which the label 120 at the leading edge has been peeled off is inserted approximately 80 mm from the backing paper insertion opening 15, and the operating part 46c of the operating member 45 is pushed down to bring the roller pair 40 into contact with it. In this case, if the backing paper 122 becomes loose at the backing paper insertion opening 15, the label roller 5 is reversed slightly by hand to eliminate the looseness.

[0044] The above steps complete the initial setup before the device is put into operation. The leading edge of the backing paper 122 does not need to be pinched with fingers and set to be wound onto the winding roller 61; it is automatically wound onto the winding roller 61 by the drive of the device. In this case, the winding roller 61 is driven to rotate with a delay of time (the time it takes for the leading edge of the backing paper to enter the notch 61b of the winding roller 61) compared to the drive of the roller pair 40.

[0045] According to the label application device of this embodiment, when pulling out the label paper 121 from the label roller 5 and setting it, the guide mechanism 30 described above allows the label paper 121 to be set stably. The roller pair 40 can be separated with a single touch of the operating member 45, and the label paper can be inserted into the separated portion and brought into contact with the roller pair 40, thus improving operability. Furthermore, since the leading edge of the label paper 121 is automatically set on the take-up roller 61, there is no need to pull out the label paper 121 and wind it onto the take-up roller 61.

[0046] In other words, when using the label application device, the label paper setting operation can be performed easily without any hassle, and furthermore, it becomes unnecessary to ensure a large excess length of label paper backing (conventionally 550 mm or more). Specifically, with the configuration of this embodiment, automatic mounting can be achieved even with an excess length of 80 mm, making it possible to reduce the excess length of backing paper during setting by about 80% compared to conventional methods (suppressing material loss).

[0047] Furthermore, the top sheet 100a, to which the label 120 has been attached by the label attachment mechanism 10, is moved from the stacked sheet by the sheet moving mechanism 20, and its front half is folded over onto the next sheet. This allows the entire apparatus for creating the labeled sheets to be made more compact, and the label attachment process to be carried out more efficiently.

[0048] Although embodiments of the labeling apparatus of the present invention have been described above, the present invention is not limited to the embodiments described above and can be modified in various ways. For example, the label removal unit that removes labels from the label paper, and the structure that transports the backing paper with the labels peeled off into the housing, can be modified as needed.

[0049] Figures 10 to 14 show modified versions of the label dispensing section in the label application device shown in Figure 1. Figure 10 is a side view of the entire device, Figure 11 is an enlarged view of the main part of Figure 10, Figure 12 is an enlarged view showing the operation (open state) of the label dispensing section, Figure 13 is an enlarged view showing the operation (closed state) of the label dispensing section, and Figure 14 shows the open state of the label dispensing section and illustrates the configuration of the part into which the backing paper is inserted.

[0050] In this modified example, the label dispenser installed downstream of the second retaining guide 33 is configured as follows to facilitate the loading of the label paper 121 into the housing during initial setup.

[0051] The roller pair 40 (drive roller 41, driven roller 42) installed inside the housing 2 is brought into contact with or separated from the housing 2 by rotating the operating member 45 which is exposed on the side surface of the housing 2. Specifically, by gripping the operating part 45A and rotating it in the direction of arrow D1, the roller pair 40 comes into contact with each other, and by rotating it in the opposite direction, they are separated.

[0052] The label removal section 37A, which is installed downstream of the second pressing guide 33 and against which the label suction section 11A is pressed, is supported movably (rotatably in this embodiment) relative to the housing 2. The label removal section 37A comprises a suction section 37a and a detachable section 37b that can be attached to and detached from the housing 2, and these are configured as a plate-like member bent at approximately a right angle.

[0053] When the suction part 37a is rotated in one direction, it becomes substantially flush with the front surface of the housing 2, and its position is fixed by a positioning and fixing means, for example, a magnet 70 (see Figure 14) provided on the housing 2 or the attachment / detachment part 37b, which comes into contact with the attachment / detachment part 37b and is attracted to it. In this state, the label paper being transported through the gap between the second press guide 33 and the housing 2 is transported into the housing through the backing paper insertion opening 15 between the lower edge of the housing 2 and the corner of the label removal part 37A while being transported, and the label 120 is attracted by the label suction part 11A during this transport (see Figure 13).

[0054] In the configuration described above, pushing the suction part 37a of the label removal unit 37A into the housing causes the backing paper insertion opening 15 to open wide. As a result, the label paper can be easily inserted into the detached roller pair 40 through the wide-opening backing paper insertion opening (see Figures 10 to 12), making the setting of the label paper even easier. From this state, by pulling up the suction part 37a of the label removal unit 37A, the rotational position of the label removal unit 37A is positioned by the magnet 70 (Figure 14), and the backing paper from which the labels have been peeled off can be transported into the housing 2 through the narrowly opened backing paper insertion opening 15.

[0055] In the above-described configuration, the present invention allows for appropriate modifications to various aspects, such as the configuration of the operating member for separating / contacting the roller pair, the configuration of the sheet moving mechanism, and the configuration of the backing paper winding device. The configuration and arrangement of the sheet pressing member can also be appropriately modified. Furthermore, the label removal unit 37A may be driven together with the operating member 45, and may move linearly in addition to rotating. Moreover, the configuration of the positioning and fixing means can also be appropriately modified. [Explanation of Symbols]
