Description

Cartridge-type labeling device with improved tension control function

[0001] The present invention relates to a cartridge-type labeling device with an improved tension control function, and more specifically, to a cartridge-type labeling device that operates in conjunction with secondary battery production equipment, wherein the tension of the release paper being unwound can be controlled by controlling the inertial rotation of the unwinding roller on which the release paper with a label attached is wound, and the tension of the release paper can be controlled during the process in which the release paper is unwound from the unwinding roller and wound onto the winding roller inside the cartridge.

[0002] Unlike primary batteries that cannot be recharged, rechargeable batteries are batteries that can be charged and discharged. Low-capacity batteries, in which a single battery cell is packaged in a pack, are used in small portable electronic devices such as mobile phones and camcorders, while high-capacity batteries, in which dozens of battery cells are connected, are widely used as power sources for driving motors in electric scooters, hybrid cars, and electric vehicles.

[0003] These secondary batteries are manufactured in various shapes, with cylindrical and prismatic shapes being representative examples. They are constructed by housing an electrode assembly, formed by interposing an insulator separator between positive and negative plates, and an electrolyte together in a case, and installing a cap plate on the case. Of course, positive and negative terminals are connected to the electrode assembly, and these are exposed and protrude to the outside through the cap plate.

[0004] Electrodes for secondary batteries have traditionally been manufactured by coating active materials, conductive materials, and binders onto a thin-walled current collector and then drying it. When manufacturing thin-walled secondary battery electrodes, problems arose, such as defects occurring due to the inclusion of external impurities when coating the active material onto the surface of the current collector, or defects occurring internally when the active material was not uniformly coated. Therefore, after manufacturing the secondary battery electrodes, they were always wound onto a winding roller, unwound to check for defects on the entire surface and mark them, and then wound onto another roller for packaging or transferred to a cutting process to remove the marked defective parts and use only the normal electrode portions.

[0005] Conventionally, defective parts on the surface of electrodes for secondary batteries were marked manually using white paint or coatings. However, with the recent surge in demand for secondary batteries, an increasingly large quantity of electrodes for secondary batteries has become required. Consequently, automated manufacturing machines have been used for mass production when manufacturing electrodes for secondary batteries. At this time, rather than humans directly marking defective parts on thin-plate electrodes using conventional paints or coatings, a method has been adopted in which a label is attached to the defective part using a labeling device for easier marking.

[0006] A typical labeling device includes an unwinding roller on which a sheet with a label is wound, and a winding roller on which the sheet unwound from the unwinding roller is wound. These rollers are configured to be rotated by a motor, which is a rotating means, so that the label on the sheet discharged from the unwinding roller is attached to a desired area, and the sheet from which the label has been removed is wound onto the winding roller.

[0007] As prior art for a labeling device, Korean Registered Patent No. 10-2083765 (Publication Date: March 2, 2020) discloses a labeling device. The labeling device comprises a cartridge that is detachably coupled to a base and has a sheet wound inside, and a pressure roller that presses the label when at least a portion of the label attached to the sheet is discharged from the cartridge to the upper side of the object to be attached when the object to be attached is conveyed parallel to the longitudinal direction of the sheet from the lower side of the base, and the pressure roller is configured to press the label by rotating eccentrically and pressing the label so that the label is attached to the object to be attached.

[0008] However, the labeling device according to the prior art with this structure had a problem in that errors occurred during label attachment because, even if the winding roller stopped during the process in which the release paper with the label attached was unwound from the unwinding roller due to the inertial rotation of the unwinding roller, the release paper was excessively unwound.

[0009] In addition, the labeling device according to the invention had a problem in that the actuator of the compression roller, which attaches the label to the conveyed object (material - copper foil, aluminum foil, etc.), was configured to be positioned perpendicular to the direction of travel of the object and apply downward pressure, and the shaft of the actuator was damaged when the compression roller applied pressure to the continuously moving object. There was also a problem in that the compression roller was damaged due to the shaft damage, or foreign matter was generated due to interference between the damaged part and surrounding components, causing damage to the object.

[0010] The objective of the present invention is to provide a means to control the tension of the release liner being unwound by controlling the inertial rotation of the unwinding roller on which the release liner with a label attached is wound in a cartridge-type labeling device for a secondary battery, and to additionally control the tension of the release liner that is unwound from the unwinding roller and wound onto the winding roller inside the cartridge.

[0011] Another technical objective of the present invention is to provide a means to prevent or minimize damage to the part operating the pressure roller by enabling the pressure roller, which presses and attaches a label to an object, to be operated by a label attachment module having a cantilever structure.

[0012] Furthermore, the problems that the present invention aims to solve are not limited to the technical problems mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0013] The above objective is achieved by a main body having an integrated structure with a receiving portion formed on the rear surface that is open in one direction; a winding chuck member provided on the drive shaft of a driving motor exposed to the front of the main body; an unwinding chuck member rotatably provided on the front of the main body; a label attachment module provided on the receiving portion configured to selectively move and return a label attachment roller disposed on the front of the main body to an attachment position; and respective detection sensors provided on one side of the front of the main body configured to detect a label sheet and detect whether the label sheet is attached. This is achieved by a cartridge-type labeling device with an improved tension control function, characterized by comprising: a release roller on which a release paper with attached labels is wound; a winding roller on which a release paper unwound from the release roller is wound; a separation block for separating the label paper from the release paper; and a guide roller for supporting and guiding the release paper, wherein the release roller is coupled to the release chuck member and the winding roller is coupled to the winding chuck member by means of attachment and detachment, wherein a first tension control means is provided inside the release chuck member to elastically press the inner surface of the release roller to control the inertial rotation of the release roller to primarily control the tension of the release paper being unwound, and a second tension control means is provided inside the cartridge, comprising a fixing block fixed to the inner surface of the cartridge and an elastic plate having one end fixed to the fixing block and the other end pressing the release paper being conveyed to the guide roller.

[0014] The main body includes a cover coupled to the back of the main body to open and close the receiving portion, and a control panel for operating and controlling the labeling device and an amplifier for the detection sensor may be installed on one side.

[0015] The label attachment module may be configured to include: a pivot member, one end of which is rotatably coupled to the inner vertical surface of the receiving portion by a support shaft; a pivot shaft, one end of which is rotatably coupled to the label attachment roller located on the front of the main body, and the other end of which passes through an operating slot formed in the front lower area of ​​the main body and is coupled to the other end of the pivot member; and an actuator, the lower end of which is coupled to the pivot member by an axis and is installed on the inner vertical surface, which reciprocates the operating rod to rotate the pivot member downward around the support shaft to move the label attachment roller to the attachment position.

[0016] The above detachable means may be configured to include at least three magnets embedded inside the cartridge; and a metal plate coupled to a portion of the front of the main body so that the cartridge is attached to the front of the main body by the magnetic force of the magnets.

[0017] On the front of the cartridge, a release liner inspection hole may be formed to allow checking of the release liner wound on the winding roller and the unwinding roller.

[0018] The first tension adjustment means comprises: a tightening bolt having an installation hole open in one direction inside; an elastic body inserted into the installation hole; and a pressure member elastically supported by the elastic body and provided so that a portion of it is exposed to the outside at the entrance of the installation hole, wherein the tightening bolt can be fastened and coupled to a fastening hole formed by penetrating the unwinding chuck member and having an internal female screw thread.

[0019] The second tension adjustment means may be configured to include an adjustment slot formed in the fixed block; and an adjustment bolt that penetrates the adjustment slot and is coupled to the inner surface of the cartridge, and to adjust the pressure of the elastic plate by using the adjustment bolt to move the position of the fixed block closer to or further away from the guide roller within the range of the adjustment slot.

[0020] The second tension adjustment means may be configured to include an adjustment hole formed in the fixed block; and an adjustment bolt that penetrates the adjustment hole and is coupled to the inner surface of the cartridge, and to adjust the pressure of the elastic plate by adjusting the rotation angle of the fixed block around the adjustment bolt.

[0021] On the inner surface of the cartridge to which the above-mentioned fixed block is coupled, a plurality of first adjustment protrusions are formed radially, and on one surface of the above-mentioned fixed block corresponding to the first adjustment protrusions, second adjustment protrusions for engaging with the first adjustment protrusions may be formed radially.

[0022] On the inner surface of the cartridge to which the fixed block is coupled, a scale may be formed to numerically check the degree of bending of the elastic plate by the second tension adjustment means.

[0023] A cartridge mounting detection sensor for detecting whether the cartridge is mounted is provided on the front of the main body, and the control panel may be configured to generate an alarm when the cartridge mounting detection sensor detects that the cartridge has been detached.

[0024] On the front of the main body in the area where the cartridge is mounted, a release paper detection sensor is provided to detect the diameter of the release paper wound on the winding roller through a detection hole formed in the cartridge, and the control panel may be configured to generate an alarm based on the detection signal of the release paper detection sensor that detects that the diameter of the release paper has reached a set diameter.

[0025] According to the present invention, in a cartridge-type labeling device for a secondary battery, the tension of the release liner to which the label is attached is superimposedly controlled through a first tension control means and a second tension control means, thereby preventing stretching of the release liner and enabling the labels attached to the release liner to be accurately attached to the target object.

[0026] In addition, as the elastic plate of the second tension adjustment means can finely adjust the pressure applied to the release paper by checking the scale value, the tension of the release paper unwound from the unwinding roller and wound onto the winding roller can be adjusted more finely and accurately.

[0027] In addition, by configuring the label attachment roller that attaches the label to the object to be attached to operate by a label attachment module with a cantilever structure, damage to related parts including the label attachment roller can be prevented or minimized.

[0028] In addition, since the cartridge installation detection sensor detects whether the cartridge is installed, an alarm is triggered if the cartridge is removed while the power is still on due to user negligence, which can significantly reduce the failure rate.

[0029] In addition, the cartridge mounting detection sensor is configured to detect the remaining amount of release paper and generate an alarm in advance, thereby making it possible to determine the cartridge replacement time in advance.

[0061]

[0062] Among the attached drawings, FIG. 1 is an exploded perspective view illustrating a labeling device according to the present invention, FIG. 2 is an assembled perspective view illustrating the labeling device illustrated in FIG. 1, and FIG. 3 is a front cross-sectional view of a cartridge illustrating the first tension adjustment means and the second tension adjustment means of the labeling device illustrated in FIG. 1.

[0063] As illustrated in FIGS. 1 to 3, the cartridge-type labeling device (10) with an improved tension control function according to the present invention is configured to operate at high speed to attach a label (R) to an object (B), and includes a first tension control means (M1) and a second tension control means (M2) to maintain appropriate tension (tension) during the process in which a release paper (S) equipped with each label (R) is drawn out from a release roller (72), passes through guide rollers (78) and a separation block (76) to separate the label (R), and is then wound onto a winding roller (74).

[0064] This is explained in more detail.

[0065] A labeling device (10) comprises a main body (20) having an integrated structure with a receiving portion (22) formed on the back surface that is open in one direction, a winding chuck member (34) provided on the drive shaft (32) of a driving motor (30) exposed to the front of the main body (22), a winding chuck member (40) rotatably provided on the front of the main body (20), a label attachment module (50) provided in the receiving portion (22) configured to selectively move a label attachment roller (52) placed on the front of the main body (20) to an attachment position and return it to its original position, each detection sensor (60) provided on one side of the front of the main body (20) configured to detect a label (R) attached to a release paper (S) and to detect whether the label (R) is attached to an object (B), a winding roller (72) on which the release paper (S) with the label (R) attached is wound, and a release paper (S) from which the label (R) has been separated It includes a cartridge (70) containing a winding roller (74) for winding, guide rollers (78) for guiding the release paper (S), and a separation block (76) for separating the label (R) attached to the release paper (S).

[0066] The main body (20) is configured to have components necessary for the operation of a labeling device (10), including a drive motor (30) and a label attachment module (50), and has an integrated structure having a receiving portion (22) that is open in one direction on the back surface as shown in FIG. 1. That is, the receiving portion (22) that is open in one direction is formed by being recessed, and the integrated structure is manufactured by a casting method or a milling method. The receiving portion (22) is opened and closed by a cover (24), and the cover (24) may be equipped with a sealing packing.

[0067] In addition, an operating hole (29) is formed connected to the front lower side and a part of the bottom side of the main body to allow the label attachment module (50) to operate. This operating hole (29) is intended to allow a rotation shaft (56) connecting the rotating member (54) of the label attachment module (50) and the label attachment roller (52) to pass through, thereby preventing interference during rotational operation.

[0068] On one side of the aforementioned main body (20), a control panel (26) for controlling a driving motor (30), a label attachment module (50), a detection sensor (60), etc., and an amplifier (28) for the detection sensor (60) are respectively provided.

[0069] The front (21) of the main body (20), that is, the front (21) corresponding to the area where the cartridge (70) is mounted, is provided with a cartridge mounting detection sensor (26A) to detect when the cartridge (70) is removed without turning off the power of the labeling device (10). The cartridge mounting detection sensor (26A) is composed of a limit switch or a photo sensor, etc., and detects whether the cartridge (70) is mounted or removed. Then, the control panel (26) generates an alarm when the cartridge mounting detection sensor (26A) detects that the cartridge (70) has been removed.

[0070] In this way, a cartridge mounting detection sensor (26A) is provided in the main body (20), and when a worker removes the cartridge (70) without turning off the power of the labeling device (10), the control panel (26) generates an alarm, thereby preventing in advance any malfunctions or safety accidents that may occur when the cartridge (70) is removed while the power of the labeling device (10) is on.

[0071] Meanwhile, as shown in FIG. 8 (a) and (b), in the front (21) of the main body (20) where the cartridge (70) is mounted, that is, in the area corresponding to the unwinding roller (72) on the front (21), a release paper detection sensor (26B) may be provided to detect the diameter of the release paper (S) wound on the unwinding roller (72) through the detection hole (77) formed in the cartridge (70).

[0072] The release paper detection sensor (26B) is composed of a photosensor or the like and is configured to detect the diameter of the release paper (S) (height of the release paper based on the outer diameter of the unwinding roller) as the release paper (S) is unwound.

[0073] That is, the release paper detection sensor (26B) can be configured to detect the diameter of the release paper (S) by receiving light reflected from the opposite wall after the light from the light-emitting sensor passes through the detection hole (77) as the release paper (S) is unwound and its diameter decreases.

[0074] And the control panel (26) is configured to generate an alarm based on the detection signal of the release paper detection sensor (26B) that detects that the diameter of the release paper (S) has reached a set diameter.

[0075] In this way, the release paper detection sensor (26B) is configured to detect the remaining amount through the diameter of the release paper (S) wound on the unwinding roller (72) and notify it as an alarm, thereby allowing the replacement time of the cartridge (70) to be determined in advance and replaced.

[0076] As described above, since the main body (20) is configured as a single unit, the inconvenience of having to assemble the main body (20) is eliminated and durability can be significantly improved. Additionally, since a control panel (26) and an amplifier (28) are installed on one side, operation is simple and maintenance of the amplifier (28) can be performed quickly and easily.

[0077]

[0078] The drive motor (30) is configured to drive the winding chuck member (34) to cause the release paper (S) to be wound onto the winding roller (74), and the winding chuck member (34) is detachably coupled to the drive shaft (32) of the drive motor (30) which penetrates the inner surface of the main body (20).

[0079] The winding chuck member (34) has a plurality of rotating protrusions (34A) formed to engage with roller protrusions (74A) formed in the inner diameter of the winding roller (74) provided in the cartridge (70).

[0080] The unwinding chuck member (40) is configured to allow the unwinding roller (72) provided inside the cartridge (70) to rotate freely, and is formed with an outer diameter smaller than the inner diameter of the unwinding roller (72), with one end connected to the front of the main body (20).

[0081] A first tension adjustment means (M1) is provided inside the unwinding chuck member (40).

[0082] The first tension control means (M1) is intended to primarily control the tension of the release paper (S) being released by controlling the inertial rotation of the release roller (72) so that the release roller (72) does not rotate due to rotational inertia even if the release of the release paper (S) stops when the release roller (72) rotates as the release paper (S) is released from the release roller (72) by the rotation of the winding roller (74) while the release cartridge (40) is inserted into the inner diameter of the release roller (72).

[0083] This first tension adjustment means (M1) comprises a fastening hole (42) formed through the unwinding chuck member (40) and having a female screw thread, a mounting hole (48A) formed with an opening (48B) that is open to one side from the inside, a tightening bolt (48) that is fastened to the fastening hole (42), an elastic body (46) that is inserted into the mounting hole (48A), and a pressure member (44) that is positioned in the opening (48B) area of ​​the mounting hole (48A), elastically supported by the elastic body (46), and has a portion exposed to the opening (48B).

[0084] That is, the tightening bolt (48) is fastened to the fastening hole (42) of the unwinding chuck member (40) to form a ball stopper structure. The aforementioned pressure member (44) is formed in a spherical shape to minimize friction with the inner surface of the unwinding roller (72) and may rotate together with the unwinding roller (72) when it rotates.

[0085] In this way, since the pressure member (44) elastically presses the inner surface of the unwinding roller (72), the unwinding roller (72) can stop immediately without rotating due to inertia even when the unwinding of the release paper (S) is stopped. Therefore, the unwinding release paper (S) can always maintain a constant tension.

[0086] And by controlling the pressure of the pressure member (44) by tightening or loosening the tightening bolt, the rotation of the unwinding roller (72) can be controlled to control the tension of the release paper (S).

[0087]

[0088] The label attachment module (50) is configured to selectively move and return the label attachment roller (52), which is positioned on the front of the main body (20), to the attachment position (P) and is provided in the receiving portion (22).

[0089] As illustrated in FIGS. 1, 5, 6 and 7, the label attachment module (50) comprises a rotating member (54) having one end rotatably coupled to the inner vertical surface of a receiving portion (22) by a support shaft (54A), a rotating shaft (56) having one end rotatably coupled to a label attachment roller (52) located on the front of the main body (20) and the other end coupled to the other end of the rotating member (54) by passing through an operating slot (29) formed in the front lower area of ​​the main body (20), and an actuator (58) having the lower end of an operating rod (58A) axially coupled to the rotating member (54) and installed on the inner vertical surface to reciprocate the operating rod (58A) so as to rotate the rotating member (54) downward around the support shaft (54A) to move the label attachment roller (52) to an attachment position (P).

[0090] In the label attachment module (50) configured in this way, when the actuator (58) moves the operating rod (58A) downward by means of a label attachment signal, the rotating member (54) of the cantilever structure rotates downward around the support shaft (54A), so that the label attachment roller (52) moves to the attachment position (P) and can attach the label paper (R) by pressing it onto the attachment target (B) being transported by the conveyor roller (55).

[0091] In addition, since the rotating member is configured in a cantilever structure and operates, even if the operating rod (58A) presses the rotating member (54) downward, damage to the parts constituting the label attachment module (50) can be prevented. That is, since the rotating member (54) is configured in a cantilever structure and the label attachment roller (52) presses the label paper (R) without interfering with the transport of the object to be attached (B), damage to the parts constituting the label attachment module (50) can be prevented.

[0092]

[0093] The detection sensor (60) includes a first optical sensor (62) installed in the main body (20) at a position corresponding to the label verification hole (71) of the cartridge (70) to detect whether there is a label (R) attached to a release liner (S) embedded in the cartridge (70), and a second optical sensor (64) installed in the main body (20) at a position corresponding to the transport position of the attachment target (B) to detect whether the label (R) has been attached to the attachment target (B) by the label attachment module (50).

[0094] The first optical sensor (62) detects whether there is a currently available label (R) on the moving release paper (S), and the control panel (26) controls the operation of the drive motor (30) that rotates the winding roller (74) based on the detection signal of the first optical sensor (62).

[0095] At this time, the control panel (26) can control the rotation of the drive motor (30) by the amount of one label (R) to be issued (moved to the attachment position) based on the detection signal of the first light sensor (62).

[0096] The first optical sensor (62) described above detects in real time, via the label paper (R), the change in the transport distance of the release paper (S) due to the increase in the diameter of the release paper (S) wound on the winding roller (74), and enables accurate transport of the label paper (R) by precisely correcting the amount of rotation of the drive motor (30).

[0097] The second optical sensor (64) checks whether the label (R) is properly attached when the attachment target (B), on which the label (R) is attached by the label attachment module (50), is transported.

[0098] The amplifier (28) for the aforementioned first and second optical sensors (62, 64) is provided on the side of the main body (20) and outputs the signal detected by each optical sensor as a digital or analog signal and transmits it to the control panel (26).

[0099] The cartridge (70) contains a release roller (72) on which release paper (S) attached to each label paper (R) is wound while maintaining a spacing, guide rollers (78) for guiding the release paper (S) being unwound from the release roller (72), a separation block (76) for separating the label paper (R) attached to the release paper (S) at the attachment position (P), and a winding roller (74) on which the release paper (S) from which the label paper (R) has been separated is wound while passing through the separation block (76).

[0100] The cartridge (70) is composed of a main body (70A) and a cover member (70B) formed in a symmetrical structure with respect to the main body (70A) and coupled to the main body (70A), and an unwinding roller (72), a winding roller (74), and respective guide rollers (78) are each rotatably coupled in the internal space between the main body (70A) and the cover member (70B).

[0101] And the wedge-shaped separation block (76) is formed so that a part of it protrudes from one side of the bottom of the main body (70A) and the cover member (70B) in which the label verification hole (71) is formed.

[0102] On the front of the cover member (70B), that is, at a position corresponding to the winding roller (74) and the unwinding roller (72), release paper inspection holes (70B-1) are formed to visually inspect the release paper (S) wound on the unwinding roller (72) and to visually inspect the release paper (S) wound on the winding roller (74).

[0103] Through these release paper inspection holes (70B-1), the operator can visually check the release paper (S) wound on the unwinding roller (72) and the release paper (S) wound on the winding roller (74).

[0104] In the inner diameter of the winding roller (74), roller protrusions (74A) are formed to engage with the rotating protrusion (34A) of the winding chuck member (34).

[0105] The winding roller (74) and the unwinding roller (72) are rotatably supported by rotational support ribs (75A, 75B) that are formed protruding from the mutually facing surfaces of the main body (70A) and the cover member (70B), respectively.

[0106] Meanwhile, the winding roller (74) and the rotating support rib (75A) are provided with a reverse rotation prevention means to prevent the winding roller (74) from rotating in the opposite direction of winding due to the tension of the release paper (S) before being mounted (coupled) to the winding chuck member (34).

[0107] The reverse rotation prevention means comprises a plurality of first teeth (74B) formed in succession at one end of the winding roller (74) facing the rotational support rib (75A) so as to be inclined in one direction, and a second tooth (75A-1) that engages with the first teeth (74B) when the rotational support rib (75A) is inserted into the inner end of the winding roller (74) to cause the winding roller (74) to rotate only in one direction.

[0108] By means of such a reverse rotation prevention means, the winding roller (74) can be prevented from rotating in the opposite direction of winding due to the tension of the release paper (S) in the state before the winding roller (74) is mounted on the winding chuck member (34), that is, in the state before the cartridge (70) is mounted on the main body (20), and can also prevent arbitrary rotation of the winding roller (74) during the process of installing the initial winding roller (74) between the main body (70A) and the cover member (70B).

[0109] With a cartridge (70) of this structure, the release paper (S) embedded in the cartridge (70) is guided to the guide roller (78) on the unwinding roller (72) side, and then passes through the narrowing separation section (76A) of the separation block (76) to separate the label paper (R). The release paper (S) from which the label paper (R) has been separated is then guided to each guide roller (78) on the winding roller (74) side and wound onto the winding roller (74). This operation is achieved by the winding roller (74) being rotated by the drive motor (30).

[0110] Meanwhile, the cartridge (70) configured as described above is attached to or detached from the main body (20) by means of a detachable means (80).

[0111] The detachable means (80) comprises at least three magnets (82) embedded inside the main body (70A) of the cartridge (70), and a metal plate (84) coupled to a part of the front (21) of the main body (20) so that the cartridge (70) is attached to the front (21) of the main body (20) by the magnetic force of the magnets (82).

[0112] In this way, a metal plate (84) is attached to the front of the main body (20), and magnets (82) are embedded in the cartridge (70). When the cartridge (70) is brought close to the metal plate (84), the cartridge (70) can be mounted on the front of the main body (20) by magnetic force, and when the cartridge (70) is pulled forward with a force capable of overcoming magnetic force, it can be separated from the main body (20).

[0113] Then, when the cartridge is mounted to the main body (20) by magnetic force, the winding chuck member (34) is inserted into the winding roller (74), the roller protrusions (74A) of the winding roller (74) and the rotating protrusions (34A) of the winding chuck member (34) engage, and the unwinding chuck member (40) is inserted into the unwinding roller (72).

[0114] In this way, since the cartridge (70) is mounted to the main body (20) by magnetic force, there is no need for a separate part or operation to connect the cartridge (70) to the main body (20) to engage the winding roller (74) with the winding chuck member (34) and to insert the unwinding chuck member (40) into the unwinding roller (72).

[0115] Meanwhile, in the interior of the cartridge (70), that is, the main body (70A), a second tension adjustment means (M2) is provided to adjust the tension of the release paper (S) by applying pressure to the guide roller (78) on the side of the release roller (72) for the release paper (S) that is released from the release roller (72) and transferred to the separation block (76).

[0116] The second tension adjustment means (M2) includes a fixing block (92) in which an adjustment hole (92A) is formed in a vertical direction and is fixed by an adjustment bolt (92B) that penetrates the adjustment hole (92A) on the inner surface of the main body (70A) of the cartridge (70), and an elastic plate (94) that presses a release paper (S), which is transported and has one end fixed to the fixing block (92), onto a guide roller (78).

[0117] The second tension adjustment means (M2) fixes one end of the elastic plate (94) to the fixing block (92) with a bolt or the like while the other end of the elastic plate (94) is in contact with the release paper (S), or fixes the fixing block (92) to the main body (70A) with an adjustment bolt (92B) while the other end of the elastic plate (94) is fixed to the fixing block (92), thereby causing the elastic plate (94) to deform and elastically press the release paper (S).

[0118] And the second tension adjustment means (M2) can adjust the elasticity of the elastic plate (94) by adjusting the adjustment slot (92A) and the adjustment bolt (92B) formed in the fixed block (92).

[0119] That is, when the other end of the elastic plate (94) is in contact with the release paper (S), the fixing block (92) is moved upward within the range of the adjustment slot (92A), and then the adjustment bolt (92B) is tightened to fix it, so the bending of the elastic plate (94) becomes large, and thus a large elastic force is generated.

[0120] Conversely, if the fixed block (92) is moved downward and then tightened to fix it, the bending of the elastic plate (94) is reduced, and a small elastic force is generated.

[0121] Therefore, the second tension adjustment means (M2) can adjust the elasticity of the elastic plate (94) by adjusting the position of the fixed block (92).

[0122] At this time, the degree of movement of the fixed block (92) can be checked through the scale (96) marked on the inner side of the main body (70A), and the elastic force of the elastic plate (94) can be quantitatively adjusted.

[0123] Among the attached drawings, FIG. 4 shows another embodiment of the second tension adjustment means (M2).

[0124] A second tension adjustment means (M2) according to another embodiment includes an adjustment hole (92E) formed in a fixed block (92), an adjustment bolt (92B) fastened to the inner surface of the cartridge (70), i.e., the inner surface of the main body (70A), through the adjustment hole (92E), and an elastic plate (94) that presses a release paper (S), which is fixed at one end to the fixed block (92) and transported at the other end, against a guide roller (78).

[0125] And on the inner surface of the main body (70A) corresponding to the periphery of the fixed block, a scale (96) is formed in an arc or circle shape to visually rotate the amount of rotation of the fixed block (92).

[0126] And on the inner surface of the cartridge (70) to which the fixing block is coupled, that is, on the inner surface of the main body (70A), a plurality of first adjustment protrusions (92C) are formed radially, and on one surface of the fixing block (92) corresponding to the first adjustment protrusions (92C), second adjustment protrusions (92D) are formed radially to engage with the first adjustment protrusions (92C).

[0127] The second tension adjustment means (M2) of this structure generates a large elastic force when the adjustment bolt (92B) is tightened after the fixed block (92) is rotated toward the guide roller (78) toward the unwinding roller (72) that guides the release paper (S).

[0128] Conversely, if the fixed block (92) is rotated in the opposite direction and the adjustment bolt (92B) is tightened, the elastic plate (94) bends slightly and generates a small elastic force.

[0129] At this time, when the adjustment bolt (92B) is tightened, the first adjustment protrusions (92C) and the second adjustment protrusions (92D) interlock, so the fixed state of the fixing block (92) can be firmly maintained.

[0130] In this way, by adjusting the rotation angle of the fixed block (92) around the adjustment bolt (92B), the pressure of the elastic plate (94) can be adjusted.

[0131] And when the fixed block rotates, the rotation angle of the fixed block (92) can be numerically checked through the scale (96).

[0132] The operation of a cartridge-type labeling device (10) with an improved tension control function configured as described above will be explained.

[0133] As shown in FIGS. 5 to 7, when a cartridge (70) containing a release roller (72) on which release paper (S) is wound, a winding roller (74), respective guide rollers (78), and a separation block (76) is pressed against a metal plate (84), the cartridge (70) is coupled to the front of the main body (20) by the magnetic force of the magnets (82).

[0134] At this time, the leading edge of the release paper (S) is fixed to the winding roller (74) via each guide roller (78) and separation block (76).

[0135] As the cartridge (70) is coupled to the main body (20), the unwinding chuck member (40) is inserted into the unwinding roller (72) and the winding chuck member (34) is inserted into the winding roller (74) and engaged.

[0136] When the unwinding chuck member (40) is inserted into the unwinding roller (72), the pressing member (44) of the first tension adjustment means (M1) presses the inner surface of the unwinding roller (72), so the unwinding roller (72) does not rotate arbitrarily.

[0137] When the cartridge (70) is mounted on the main body (20) through the above-described process, the drive motor (30) performs an operation for winding based on the signal detected by the detection sensor (60).

[0138] When the winding roller (74) is driven by the drive motor (30), the release paper (S) is unwound on the unwinding roller (72), then passes through the guide roller (78), the separation block (76), and other guide rollers (78), and is then wound onto the winding roller (74).

[0139] In this process, the label (R) attached to the release liner (S) is separated from the release liner (S) by the separation block (76) and then attached to the object to be attached (B) by the label attachment roller (52).

[0140] Then, when the winding roller (74) stops, the unwinding of the release paper (S) stops, and the unwinding roller (72) is prevented from rotating inertia by the first tension control means (M1).

[0141] That is, since the pressure member (44) elastically presses the inner surface of the unwinding roller (72), the inertial rotation phenomenon can be prevented even if the unwinding roller (72) stops.

[0142] Meanwhile, when the release paper (S) is unwound from the unwinding roller (72), guided to each guide roller (78), and wound onto the winding roller (74), the elastic plate (94) of the second tension adjustment means (M2) elastically presses the release paper (S) against the guide roller (78), so the tension of the release paper (S) can always be maintained at a constant level.

[0143] When the release liner (S) passes through the separation block (76) in the aforementioned process, the label (R) separated from the release liner (S) is attached to the object to be attached (B) by a label attachment roller (52) that is configured with a cantilever structure and operates downward.

[0144] Since the label attachment roller (52) is rotatably coupled to the end of the rotating member (54) which operates in a cantilever structure, no bending load is generated on the operating rod (58A) of the actuator (58) when the attachment object (B) is transported.

[0145] Therefore, compared to a conventional device in which the label attachment roller (52) is pressed in a direction perpendicular to the transport direction of the attachment target (B), the failure rate is significantly lower.

[0146]

[0147] Although specific embodiments of the present invention have been described and illustrated above, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should not be understood individually from the technical spirit or perspective of the present invention, and the modified embodiments should be considered to fall within the scope of the claims of the present invention.

[0148] The cartridge-type labeling device with an improved tension control function according to the present invention is configured to prevent sagging of the release paper with the attached label through a first tension control means and a second tension control means, thereby enabling the label papers attached to the release paper to be accurately attached to the target object. Furthermore, the labeling device according to the present invention is configured to finely adjust the pressure applied to the release paper by the elastic plate of the second tension control means by numerically verifying the pressure applied to the release paper, thereby enabling more fine and accurate control of the tension of the release paper unwound from the unwinding roller and wound onto the winding roller. Additionally, the labeling device according to the present invention is configured such that the label attachment roller, which attaches the label paper to the target object, is operated by a label attachment module having a cantilever structure, thereby preventing or minimizing damage to related parts including the label attachment roller. In this regard, the present invention overcomes the limitations of existing technology, and thus, not only is there sufficient possibility for the commercialization or business of the applied device rather than just the use of related technology, but it is also an invention with industrial applicability as it is clearly and practically implementable.
