  2 includes a label supply unit 103 that rotatably holds a supply reel 102, a transfer unit 105 that transfers a label tape 104 wound around the supply reel 102, and a transfer unit 105. The label peeling part 106 which turns back the transfer direction of the label tape 104, and the winding-up part 107 for winding up the label tape 104 sent out from the transfer part 105 were provided.

  The label tape 104 is a temporary attachment of a plurality of labels 104b to the belt-like mount 104a with a predetermined interval. The label 104b is attached to a label application object (not shown) at the tip of the label peeling unit 106, 104a was peeled off.

  The conventional label sticking apparatus 101 holds the supply reel 102 on the shaft body 103a of the label supply unit 103, and feeds the fed label tape 104 to the label peeling unit 106 via the tension roller 108 and the first guide roller 109a. It was.

  The belt-like mount 104a that is reversed by the label peeling unit 106 and peeled off the label 104b passes under the second guide roller 109b and above the third guide roller 109c, and then to the feed roller 105a that is the transfer unit 105. It was wound up, and was finally wound up in a roll shape by the winding unit 107.

  The label peeling unit 106 includes a label peeling plate swing mechanism 106b for rotating the label peeling plate 106a and a label detection sensor 106c. When the leading end of the label 104b is detected, a signal is sent to a control unit (not shown). The servo motor 106d of the label peeling plate swing mechanism 106b to be connected is rotationally driven to swing down the label peeling plate 106a, thereby sticking the tip of the label 104b protruding from the label peeling plate 106a to a predetermined position of the label sticking object. It was.

  Since the conventional label sticking apparatus 101 transports while applying tension to the label tape 104, the tension change is absorbed by the interposed tension roller 108, but the normal label tape 104 is usually fed by the feed roller 105 a of the transport unit 105. A predetermined tension is applied by a winding force, and the force is maintained between the label supply unit 103 and the feed roller 105a.

  However, if the label tape 104 is not wrapped and the end of the supply reel 102 is removed, or if cutting occurs in the middle of the tape, there is a drawback in that labeling is impossible because tension is lost throughout the tape. It was.

  Further, when the label tape 104 is no longer wound and replaced with a new tape, all of the old label tape 104 remaining in the label sticking apparatus 101 must be removed, resulting in increased waste of labels. There were drawbacks.

  In addition, when a cut occurs in the middle and the old label tape and the new label tape are connected and used, after loosening all contact with each roller in the entire transfer section of the old label tape, Tensions had to be applied while adjusting each part, and the joining process was a complicated operation.

  The present invention has been made to solve the above-mentioned problems of the label applicator, and is capable of labeling while maintaining the tension in the vicinity of the label peeling plate even if the label tape is detached from the supply reel or is cut in the middle. It is an object of the present invention to provide a label sticking device that is easy to connect, and that can reduce the number of discarded labels.

In order to solve the above-described problem, a label sticking device of the present invention includes a label supply unit that winds a belt-like mount on which a plurality of labels are temporarily attached at a predetermined interval around a supply reel, and rotatably holds the supply reel. A transfer unit that transfers while sandwiching the belt-like mount, a label peeling plate that peels off the label from the belt mount by folding back the direction of transport of the belt-like mount, and a label pasting object at the tip of the label peel-off plate In a label sticking apparatus comprising a winding part for winding the belt-like mount after sticking the label, the transfer part is arranged in the base direction of the label peeling plate and is rotated by an independent drive motor. It is a triple transfer roller, and the upper and middle rollers transfer the band-shaped mount sandwiched in the direction of the leading edge of the label peeling plate, and the middle and lower-stage rollers transfer the band-shaped mount sandwiched by the winding unit Transferred to the rotational speed of the upper roller was set to slower than the middle rollers, the rotational speed of the lower roller is characterized in that to set the faster than the middle rollers.

  The upper middle roller is a roller for pulling out the belt-like mount from the supply reel, and the middle and lower roller is a roller for applying tension to the belt-like backing folded along the upper and lower surfaces of the label peeling plate. The upper, middle, and lower three-stage transfer rollers are always held with tension when transporting the belt-like backing sheet, and the belt is placed before and after that, that is, between the label supply unit and the upper and middle rollers, or from the middle and lower rollers to the take-up unit. This tension is maintained even if the mount is cut.

The transport rollers are upper, middle, and lower rollers that are rotated by independent drive motors. The rotation speed of the upper rollers is set slower than that of the middle rollers to maintain the tension on the label peeling plate, and the rotation speed of the lower rollers is Set faster than the middle roller.

The label supply unit of the label sticking device according to claim 2 has a pair of placement rollers on which the supply reel is rotatably mounted, and one of the placement rollers is disposed on an outer periphery of the supply reel that abuts the supply reel. On the other hand, a rotational driving force that rotates in synchronization with the transfer speed of the transfer roller in the transfer direction of the belt-like mount is applied.

  The interval between the placement rollers is such that the supply reel with the belt mount fully wound or idle can be always stably mounted, and one loading roller for applying the rotational driving force is synchronized with the transfer speed of the transfer roller. Rotate. When replacing the supply reel, the used supply reel can be supplied simply by moving it upward, and a new reel can be set simply by being placed on the mounting roller.

  In the label sticking device of the present invention, the upper, middle, and lower three transfer rollers are arranged at the base of the label peeling plate, and tension is applied to the belt-like mount folded along the upper and lower surfaces of the label peeling plate. Labeling is possible even when the belt-like mount is cut between the upper and middle rollers or between the middle and lower rollers and the winding portion, and the tape joining process can be facilitated. Also, the number of discarded labels can be reduced.

Further, since the upper, middle and lower rollers of the label applying device are rotated by independent drive motors, tension adjustment with the label peeling plate can be easily performed.

Since the label supply part of the label sticking apparatus according to claim 2 has a pair of mounting rollers on which the supply reel is rotatably mounted, the supply reel can be easily replaced. In addition, since a rotational driving force is applied to the supply reel from one loading roller, the belt-shaped mount is smoothly fed. Since the feeding speed coincides with the abutted belt-like mount, it is easy to synchronize with the feeding speed of the feeding roller.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a front view of the label sticking apparatus. The label sticking device 1 is a device that performs labeling while continuously conveying containers or the like as label sticking objects 2 on a conveyor 3, and a label supply unit 5 that rotatably holds a supply reel 4, and the supply reel 4. A transfer part 7 for transferring the label tape 6 to be wound around, a label peeling part 8 for turning back the transfer direction of the label tape 6, and a take-up part 9 for winding the label tape 6 fed from the transfer part 7. It has.

  The label tape 6 is for temporarily attaching a plurality of labels 6b to the belt-like mount 6a at predetermined intervals. The label tape 6 is affixed to the label application object 2 at the tip of the label peeling portion 8, and the belt-like mount 6a. Peel from.

  The label supply unit 5 includes a pair of placement rollers 5a and 5b on which the supply reel 4 is rotatably mounted. One of the placement rollers 5a receives the rotational driving force of the servo motor 5c and comes into contact therewith. A rotational force is applied to the outer periphery of the supply reel 4 in the transfer direction of the label tape 6.

  The interval between the mounting rollers 5a and 5b is such that the supply reel 4 is always stable when the label tape 6 is fully wound (state shown by a solid line in FIG. 1) or almost idle (state shown by a two-dot chain line in FIG. 1). One mounting roller 5 a that applies a rotational driving force rotates in synchronization with the transfer speed of the label tape 6. That is, even if the radius of the supply reel 4 changes with respect to a constant transfer speed of the label tape 6, it can be handled with a constant motor rotation speed, so that the control becomes simple.

  The label tape 6 fed out from the supply reel 4 is sent to the transfer unit 7 and the label peeling unit 8 via the supply roller 10, the tension roller 11, and the guide roller 12. The tension roller 11 can move up and down along the guide 11a. An upper limit position and a lower limit position are set in the guide 11a. When the tension roller 11 reaches the upper limit position, the label in the label supply unit 5 is connected via a control unit (not shown). The transfer speed of the tape 6 is increased to loosen excess tension, and when the lower limit position is reached, the rotation speed of the mounting roller 5a is decreased so that a predetermined range of tension is applied to the label tape 6.

  The transfer unit 7 includes upper, middle, and lower three-stage transfer rollers 7 a, 7 b, and 7 c that are arranged in the base direction of the label peeling unit 8. These transfer rollers 7a, 7b, and 7c are attached to a substantially T-shaped swing plate 8a constituting the label peeling portion 8, and rotate by receiving the rotational driving force of the servo motors 7d, 7e, and 7f, respectively.

  The upper transfer roller 7a and the servo motor 7d connected to the upper transfer roller 7a are supported by a motor hanger 7g rotatably attached to the swing plate 8a, and the middle transfer roller 7b and the middle transfer roller 7b are operated by operating a lever 7i protruding from the motor hanger 7g. Is made. Similarly, the lower transfer roller 7c and the servo motor 7f are supported by a motor hanger 7h and are brought into and out of contact with the intermediate transfer roller 7b by operating the lever 7j.

  Both ends of the top of the swing plate 8a are coupled to the pins 8b and 8c, respectively, and swings when receiving the reciprocation of the link 8e connected to the cam 8d.

  A label peeling plate 8f is attached to the front end portion of the swing plate 8a, and the front end portion extends toward the label attaching object 2 conveyed on the conveyor 3. The label tape 6 is turned at the front end of the release plate 8f, whereby the label 6b peeled off from the belt-like mount 6a is fed forward of the release plate 8f.

  Further, a bracket 8g protrudes from the upper end of the swing plate 8a and a label sensor 8h is mounted. An arm 8j for attaching a pressing roller 8i is attached to the bracket 8g.

  On the other hand, on the conveyor 3 side, a sensor 3a and an air cylinder 3b that is actuated by a signal thereof are disposed, and a stopper 3c projects from the upper surface of the conveyor 3.

  When the sensor 3a detects the label pasting object 2 conveyed by the conveyor 3, a signal is sent from a control unit (not shown) to the air cylinder 3b so that the stopper 3c protrudes on the conveyor 3 to capture the label pasting object 2. At this time, the label sensor 8h also detects the tip of the label 6b and grasps the position of the label 6b.

  Driving of the servo motors 7d, 7e, 7f and the cam 8d of the transfer unit 7 is controlled by a control unit (not shown), and the tip of the label 6b fed out from the label peeling plate 8f in accordance with the position of the label pasting object 2 and the label 6b. Is rotated at the same timing so as to be attached to a predetermined position on the upper surface of the label application object 2, and the head is swung as shown by the two-dot chain line in FIG.

  Thereafter, the stopper 3c is lowered to feed the label application object 2 forward, and the label 6b is attached by a press roller 8i provided in front.

  On the other hand, the belt-like mount 6a from which the label 6b has been peeled passes through the lower surface side of the label peeling plate 8f, is sandwiched between the middle and lower transfer rollers 7b, 7c, and is sent to the winding unit 9 via the guide roller 13. Similarly to the label supply unit 5, the winding unit 9 has a pair of mounting rollers 15a and 15b on which the winding reel 14 is rotatably mounted. One of the mounting rollers 15a is a servo motor 15c. Upon receiving the rotational driving force, a rotational force is applied in the winding direction of the belt-like mount 6a to the outer periphery of the winding reel 14 that comes into contact.

  As described above, the upper and middle transfer rollers 7a and 7b in the transfer unit 7 transfer the label tape 6 to be sandwiched in the direction of the leading end of the label peeling plate 8f, and the middle and lower transfer rollers 7b and 7c receive the belt-like mount 6a to be sandwiched. It moves in the direction of the winding unit 9. Each of the transfer rollers 7a, 7b, and 7c is rotated by receiving the rotational driving force of the servo motors 7d, 7e, and 7f, and the rotational speed of the upper roller 7a to maintain the tension of the label tape 6 on the label peeling plate 8f. Is set slower than the middle roller 7b, and the rotational speed of the lower roller 7c is set faster than the middle roller 7b.

  The upper and middle transfer rollers 7 a and 7 b are rollers for pulling out the label tape 6 from the supply reel 4, and the middle and lower transfer rollers 7 b and 7 c are rollers for applying tension to the label tape 6. The upper, middle, and lower three-stage transfer rollers 7a, 7b, and 7c are always sandwiched with tension when the label tape 6 is transferred, that is, before and after that, that is, between the label supply unit 5 and the upper and middle transfer rollers 7a and 7b. Alternatively, even if the label tape 6 is cut from the middle and lower transfer rollers 7b and 7c to the winding unit 9, this tension is maintained.

  This label sticking apparatus can be applied not only to a label sticking object that is transported on a conveyor but also to a label sticking object that is automatically transported.
