Description

  The present invention relates to a sticking device for a double-sided printing label, and more particularly to a sticking device for a double-sided printing label for automatically sticking a front surface label and a back surface label of a double-sided printing label to the front and back surfaces of an adherend at once.

  For example, in a supermarket, an operator (for example, a store clerk) prints various information about food on a label with a label printer and issues it, and affixes it to a plastic container (an example of an adherend) containing food such as sugar beet. After that, display it on the display shelf.

  In this case, more information can be provided to the consumer by attaching labels to both the front and back surfaces of the container.

  Conventionally, as a method of sticking two labels on the front and back of a container, different information is printed on both sides of a double-sided printing label with a double-sided printer, and the operator peels off the front surface label and the back surface label by hand. It was pasted on the front and back.

  Also, using a single-sided label sticking device, first the first label is stuck on the surface of the container (upward sticking), then it is transported by a conveyor or the like and placed on the bottom of the container with another label sticking device. A two-step pasting operation was performed to attach the first label (underlay) (for example, Patent Document 1).

  By the way, many food containers are used in which the lid is supported by the container body so as to be swingable and openable. In this case, the lid is not opened after the food is put in the container. In addition, the lid is usually sealed to the container by a sealing member such as a rubber band or a tape, or heat welding.

  A sticking device for a double-sided printer according to an embodiment of the present invention is provided with a double-sided printing by a double-sided printer, and a label for a front surface and a back surface label of the issued double-sided printed label are once applied to the front and back surfaces of an adherend. It is configured as a device for automatically sticking to.

  Hereinafter, the double-sided printer, the sticking device, and the double-sided label used are described in detail.

[Double-sided printer]
As shown in FIG. 1, the double-sided printer 1 mainly includes a belt-like double-sided print label 3 feeding reel device 10, a transfer path 4, a paper sensor 5, a transfer mechanism 6, a print mechanism 7, and a printer housing 2. Various members such as an opening / closing mechanism 9 for opening / closing the width guide lock mechanism 8, the transfer mechanism 6 and the printing mechanism 7, and a cutting unit 19 are provided. Then, the double-sided printing label 3 </ b> A that has been printed on both sides by the printing mechanism 7 and cut by the cutting unit 19 is fed out from the issuing port 11 and directed toward the pasting device 20 by the issuing mechanism 12 provided outside the printer housing 2. Issued.

  The belt-like double-sided printing label 3 is wound and supported in a roll shape around the rotation shaft of the paper feed reel device 10, and is sent out to the transfer path 4 by the transfer mechanism 6.

  The transfer path 4 is a path for transferring the double-sided print label 3 sent out from the paper supply reel device 10 to the issue port 11, and in order from the paper supply reel device 10 side, the width guide lock mechanism 8, the paper sensor 5, A printing mechanism 7 including a first printing unit 7A and a second printing unit 7B, a cutting unit 19, and an issuing mechanism 12 are provided.

  The width guide lock mechanism 8 is a mechanism in which the double-sided print label 3 sent out to the transfer path 4 is transferred without meandering by regulating the width direction of the double-sided print label 3.

  The transfer mechanism 6 includes a fixed drive roller 13 and a driven roller 14 that can move in the vertical direction with respect to the drive roller 13. The double-sided print label 3 is transferred along the transfer path 4 by sandwiching the double-sided print label 3 between the two rollers 13 and 14 and rotationally driving the driving roller 13.

  The paper sensor 5 detects a position detection mark E (see FIG. 3) provided on the double-sided print label 3, and detects the relative position of the double-sided print label 3 with respect to the transfer mechanism 6, the printing mechanism 7, the opening / closing mechanism 9, and the like. To do.

  The first printing unit 7 </ b> A and the second printing unit 7 </ b> B are for printing predetermined information on the front and back surfaces of the double-sided printing label 3, and are sequentially arranged along the transfer path 4. Of the first printing unit 7A and the second printing unit 7B, the first printing unit 7A provided on the upstream side is mainly composed of the thermal head 17 and the platen roller 15. The double-sided printing label 3 sent from the paper supply reel device 10 is sandwiched between the thermal head 17 and the platen roller 15. Then, the platen roller 15 rotates in a sandwiched state, and the double-sided print label 3 is printed and conveyed. As a result, the print information is printed on one side (for example, the back side) of the double-sided print label 3.

  The second printing unit 7B provided on the downstream side is also composed of the thermal head 18 and the platen roller 16 as in the first printing unit 7A, but the vertical relationship between the thermal head 18 and the platen roller 16 is reversed. doing. Thereby, the printing information is printed on the other side (for example, the front side) of the double-sided printing label 3.

  As the types of the first printing unit 7A and the second printing unit 7B, a thermal coloring type thermal printer method and a transfer type thermal printer method can be suitably used. In the case of a transfer type thermal printer system, an ink ribbon (not shown) is required in addition to the thermal heads 17 and 18 and the platen rollers 15 and 16 as the configuration of the first printing unit 7A and the second printing unit 7B.

Further, the transfer amount of the upstream platen roller 15 is set slightly larger than the transfer amount of the double-sided print label A by the transfer mechanism 6. Thereby, when the double-sided print label A is transferred from the upstream side to the downstream side, a predetermined tension can be applied to the double-sided print label A, so that the double-sided print label A on the transfer path 4 can be prevented from being loosened.

  Further, when the double-sided printing label 3 is reversely transferred from the downstream side toward the upstream side, the upstream thermal head 17 and the downstream thermal head 18 are opened from the platen rollers 15 and 16 by the opening / closing mechanism 9 described later. Thus, the platen rollers 15 and 16 are reversely transferred only by the transfer mechanism 6 while being rotated in the direction of forward transfer (not reverse transfer). This prevents slack in the double-sided printed label 3 even when reversely transporting.

  The cutting unit 19 is composed of a fixed blade 19A and a movable blade 19B that can move forward and backward with respect to the fixed blade 19A, and double-sided printing in which both sides are printed on the front and back surfaces by the first and second printing units 7A and 7B. By cutting the label 3 at the position detection mark E, the label 3 is cut into one double-sided printing label 3A.

  The opening / closing mechanism 9 is a mechanism capable of opening / closing (pushing up and returning) the driven roller 14 in the transfer mechanism 6 with respect to the driving roller 13, and an upstream thermal head 17 and a downstream thermal head 18 in the printing mechanism 7. Are respectively openable and closable with respect to the upstream platen roller 15 and the downstream platen roller 16 (can be pushed down and pushed up, and can be returned).

  The issue mechanism 12 includes a pair of upper and lower nip rollers 12A and 12B provided outside the issue port 11, and nips the cut double-sided print label 3A toward the sticking device 20 with the nip rollers 12A and 12B. .

  According to the double-sided printer 1 configured as described above, the double-sided printing label 3A printed on the surface of the double-sided printing label 3 by the printing unit 7 and cut into one sheet by the cutting unit 19 is issued by the issuing mechanism 12.

  In the present embodiment, the adherend 22 will be described using an example of a plastic lidded container (hereinafter simply referred to as “container 22”) used as a food container such as a supermarket. As shown in FIG. 2, the container 22 with a lid has a substantially rectangular container body 22A and a lid 22B connected to each other at one of four sides, and the lid 22B is shaken via the connected hinge portion 22C. It opens and closes dynamically.

  An example of a panorama label (hereinafter referred to as “panorama label 3A”) will be described as the double-sided printing label 3A. As shown in FIGS. 3A and 3B, the panoramic label 3A is formed by folding one label in half and adhering it with an adhesive B so that it can be peeled off. Is formed. 3A and 3B show the state of the strip-like panorama label 3 before being cut into one panorama label 3A by the cutting unit 19 in the duplex printer 1. FIG.

  Further, on the opposite side of the folded portion C of the panoramic label 3 which is folded in half, a paste-killing portion D (width up to a broken line) for separating the front surface label X and the back surface label Y is formed. Further, the panorama label 3 is printed with a position detection mark E for detecting a cutting position for cutting each sheet, and is cut into a predetermined width W by the cutting unit 19 of the double-sided printer 1 described above.

  As shown in FIGS. 4 and 5, the sticking device 20 includes a pressing means 26 that closes the lid 22 </ b> B of the container 22 along the transport direction of the first belt conveyor 24 that transports the container 22, and the container 22 in the first direction. Transfer means 30 for transferring from the belt conveyor 24 to the second belt conveyor 28 is provided. Further, detection sensors 26C and 30D for detecting the pressing timing of the pressing means 26 and the transfer timing of the transfer means are provided on the side of the first belt conveyor 24, and the detection information is detected by the duplex printer 1 and the pasting device 20. Is input to the controller 31 that controls

  Although it does not specifically limit as the pressing means 26, For example, the following can be employ | adopted. That is, the pressing means 26 is provided at a lateral position in the width direction of the first belt conveyor 24, and the swing plate 26B is attached to the swing shaft 26A provided substantially parallel to the first belt conveyor 24 by the arrow AB. What is supported so that it can swing in the direction can be adopted. One end of the swing shaft 26A is connected to a swing drive source (not shown) (not shown), and is driven by a command from the controller 31.

  On the other hand, the container 22 with the lid 22B opened is conveyed on the first belt conveyor 24 in such a direction that the hinge portion 22C is close to the swing plate 26B. When the container 22 comes to the position of the pressing means 26, the swing plate 26B swings in the direction of arrow B. As a result, the lid 22B of the container 22 with the lid 22B open is closed by swinging the swing plate 26B in the B direction.

  Next, the container 22 is conveyed to a transfer position where the container 22 is transferred from the first belt conveyor 24 to the second belt conveyor 28 with the lid 22 </ b> B closed by the upper pressing guide rail 29. The container 22 conveyed to the transfer position is transferred to the second belt conveyor 28 by the transfer means 30. Here, the transfer means that the container 22 is transferred from the first belt conveyor 24 to the second belt conveyor 28.

  Any means can be used as the transfer means 30 as long as the container 22 can be transferred from the first belt conveyor 24 to the second belt conveyor 28. For example, the rod 30B moves the piston in the CD direction by the cylinder body 30A. It is possible to employ a configuration in which the contact plate 30C is provided at the rod tip. The cylinder body 30 </ b> A is driven by a command from the controller 31. Accordingly, the container 22 is pushed out from the first belt conveyor 24 to the second belt conveyor 28 by the rod 30 </ b> B performing the extending operation at the timing when the container 22 is conveyed to the transfer position. As a result, the container 22 is transferred from the first belt conveyor 24 to the second belt conveyor 28. If the first belt conveyor 24 and the second belt conveyor 28 are one continuous conveyor, the transfer means 30 is not necessary.

  The second belt conveyor 28 includes two parallel endless belts 28A and 28A provided below the both ends of the container width direction along the direction in which the container 22 is conveyed. Endless belts 28A and 28A are looped around a pair of rollers.

  A pair of parallel guide rails 32 and 32 along the endless belts 28A and 28A are provided above the two endless belts 28A and 28A. The distance between the endless belts 28 </ b> A and 28 </ b> A and the guide rails 32 and 32 is substantially equal to the thickness of the container 22. As a result, the container 22 conveyed by the second belt conveyor 28 has an upper surface and a lower surface sandwiched between the pair of endless belts 28A and 28A and the pair of guide rails 32 and 32 at both ends in the width direction. The 22 lids 22B are conveyed without being opened.

  Instead of the pair of guide rails 32, 32, the same belt conveyor 28 may be provided. That is, the container 22 is conveyed while being sandwiched between the upper and lower surfaces of the container 22 by the endless belts 28A and 28A.

  A holding mechanism for holding one panoramic label 3A issued from the double-sided printing printer 1 is provided at a position downstream of the second belt conveyor 28 and at the issuing port 11 of the double-sided printing printer 1, and the label for the surface in the held state. A peeling mechanism that peels X and the back surface label Y, and a contact mechanism that makes the front surface label X and the back surface label Y contact the front and back surfaces of the container 22 conveyed by the second belt conveyor 28. A holding / peeling / contact mechanism 34 having three mechanisms is provided.

  As the holding / peeling / contacting mechanism 34, as shown in FIG. 4 and FIG. 5, one constituted by four rollers can be suitably employed. That is, the holding / separating / contact mechanism 34 is mainly composed of a pair of upper and lower front rollers 36A and 36B and a pair of upper and lower rear rollers 38A and 38B, and the roller axis direction is the moving direction of the second belt conveyor 28. It arrange | positions so that it may orthogonally cross.

  The front rollers 36A and 36B are rotatable rollers having a suction function on the roller surface. The front rollers 36A and 36B perform a vertical movement in a direction in which the pair of front rollers 36A and 36B approach and separate from each other and a horizontal movement in the transport direction. Provide a mechanism to perform. The front rollers 36A and 36B can be rotated in the direction of the arrow by a rotation drive source (not shown).

  The rear rollers 38A and 38B are rotatable rollers and include a mechanism that vertically moves in a direction in which the pair of rear rollers 38A and 38B approach and separate from each other.

  A first detection sensor 40 and a second sensor 42 that detect the container 22 are provided in the middle of the second belt conveyor 28, and detection information is input to the controller 31. The controller 31 drives the double-sided printer 1 and the pasting device 20 to issue a panoramic label 3A from the double-sided printer 1, and a peeling timing to peel the panoramic label 3A into the front surface label X and the back surface label Y. The conveyance timing of the container 22 and the contact timing of the front surface label X and the rear surface label Y with respect to the front and back surfaces of the container 22 are controlled.

  FIG. 6 is a diagram for specifically explaining an example of the vertical movement and horizontal movement mechanisms of the front rollers 36A and 36B.

  As shown in FIG. 6, among the pair of upper and lower front rollers 36A and 36B, a pair of support plates 44 and 44 are provided in the vertical direction on both end sides of the upper front roller 36A, and the support plates 44 and 44 are vertically disposed. Long holes 46 are formed in the direction. The upper front roller 36A is supported by a pair of rotating shafts at both ends of the roller so as to be slidable in the long holes 46 and 46 via respective bearings 48 and 48. Furthermore, the main body portions 50A and 50A of the cylinder devices 50 and 50 are fixed to the support plates 44 and 44, and cylinder rods 50B and 50B are provided downward from the main body portions 50A and 50A. The bearings 48 are supported at the tips of the cylinder rods 50B and 50B. As a result, the cylinder devices 50, 50 are driven and the cylinder rods 50B, 50B expand and contract in the EF direction, whereby the upper front roller 36A moves in the vertical direction along the long holes 46, 46.

  The basic structure of the lower front roller 36B is the same as that of the upper front roller 36A described above, but the main body portions 50A and 50A of the cylinder devices 50 and 50 are fixed to the support plates 44 and 44, respectively. The difference is that cylinder rods 50B and 50B are provided upward from 50A and 50A.

  Therefore, when the cylinder device 50 of the upper front roller 36A and the lower front roller 36B performs the contraction operation (E direction), the front rollers 36A and 36B are separated from each other, and when the extension operation (F direction) is performed, the front rollers 36A. , 36B approaches.

  Also, four horizontal rails 52, 52 parallel to the width of the pair of support plates 44, 44 are provided above the upper front roller 36A and below the lower front roller 36B. It is provided along the direction. The upper ends of the pair of support plates 44 and 44 that support the upper front roller 36 </ b> A are supported by the rails 52 and 52 via the self-propelled moving bodies 54 and 54. Similarly, the lower ends of the pair of support plates 44 and 44 that support the lower front roller 36B are supported by the rails 52 and 52 via the self-propelled moving bodies 54 and 54, respectively. As the self-propelled moving body 54, for example, a type in which a pair of wheels (not shown) sandwiching the rail 52 is driven by a motor (not shown) can be used.

  Accordingly, the pair of upstream rollers 36 </ b> A and 36 </ b> B can move in the GH direction along the conveyance direction of the second belt conveyor 28.

  FIG. 7 is an external view of the front rollers 36A and 36B. The front rollers 36A and 36B are provided with a pair of hollow rotating shafts b and b at both ends of a hollow roller body a. In addition, one end of the pair of rotating shafts b and b is closed, and the other end is connected to the vacuum tube 58 via the rotary joint 56, and the vacuum tube 58 is connected to a vacuum generator (not shown). It is. Further, a sponge-like cylindrical body c having the same width as the roller body a is fitted outside the roller body a, and a large number of holes d communicate with the roller body a and the cylinder c. Formed. Thus, when the vacuum generator is driven, an adsorption force (suction force) is generated on the surface of the cylindrical body c of the preceding rollers 36A and 36B.

  The structure of the rear rollers 38A and 38B is the same as that of the front rollers 36A and 36B described above, except that the rear rollers 38A and 38B are directly supported by the rail 52 without the self-propelled moving body 54 for lateral movement. This is different from the preceding rollers 36A and 36B. Also, unlike the former rollers 36A and 36B, there is no mechanism for generating an attracting force on the roller surface, but a sponge-like cylindrical body (not shown) without a hole is fitted outside the roller body. Be dressed. In this manner, by providing sponge-like cylindrical bodies on the roller surfaces of the front rollers 36A and 36B and the rear rollers 38A and 38B, the panorama label 3A issued from the double-sided printer 1 is sandwiched and held even if the thickness slightly changes. It is easy and does not damage the panorama label 3A. In addition, when the panoramic label 3A is affixed to the container 22, even if the shape and thickness of the container 22 are slightly different, the sponge-like cylindrical body absorbs the thickness and shape.

  In the following description, the upper front roller 36A and the upper rear roller 38A are collectively referred to as upper rollers 36A and 38A, and the lower front roller 36B and the lower rear roller 38B are collectively referred to as lower rollers 36B and 38B. There is also.

  As shown in FIGS. 4 and 5, the container 22 to which the panorama label A is pasted by the pasting device 20 is transferred from the second belt conveyor 28 to the third belt conveyor 60 and is transported to the final transport destination.

  Next, the effect of attaching the panorama label 3A to the lidded container 22 by the attaching device 20 configured as described above will be described with reference to the schematic diagrams of FIGS.

  As shown in FIG. 8, the container 22 in which food is stored and the lid 22 </ b> B is opened is conveyed by the first belt conveyor 24. The controller 31 presses the lid 22B by swinging the swing plate 26B of the pressing means 26 in the B direction based on the timing when the container 22 is detected by the detection sensor 26C. As a result, the lid 22B of the container 22 is closed.

  Next, the controller 31 drives the contact plate 30C of the transfer means 30 in the extending direction based on the timing when the container 22 is detected by the detection sensor 30D, and the container with the lid 22B closed is moved to the first belt conveyor 24. To the second belt conveyor 28.

  Next, the controller 31 outputs command information to the printing mechanism 7 of the double-sided printer 1 at the timing when the container 22 transferred to the second belt conveyor 28 is detected by the first sensor 40, and issues a single panorama to be issued. Double-sided printing is performed on the label 3A. Further, the controller 31 drives the cutting unit 19 to cut the panoramic label 3A printed on both sides, and then drives the issuing mechanism 12 to move the upper roller 36A in a separated state as shown in FIG. 9A. , 38A and the lower rollers 36B, 38B. The direction of the issued panorama label 3A is issued so that the paste-killing portion D faces the container 22 conveyed on the second belt conveyor 28.

  Next, the controller 31 controls the cylinder device 50 to vertically move the upper rollers 36A and 38A and the lower rollers 36B and 38B in a direction approaching each other, as shown in FIG. 9B. Thus, the issued panorama label 3A is sandwiched between the upper rollers 36A and 38A and the lower rollers 36B and 38B.

  Next, as shown in FIG. 9C, the controller 31 controls a rotation drive source (not shown) to rotate the upper front roller 36A and the lower front roller 36B to which the suction force is applied in the direction of the arrow. To do. In this case, air is ejected from the air nozzle 62 having a slot-shaped air outlet larger than the width W of the panorama label 3A (see FIG. 3B) toward the paste-killing portion D of the panorama label A, and the paste-killing portion D. It is preferable to assist the peeling. As a result, as shown in FIG. 9D, the panorama label 3A starts to be peeled off from the paste-killing portion D, the upper label X is sucked and held by the upper front roller 36A, and the lower label Y is moved to the lower front stage. It is sucked and held by the roller 36B. On the other hand, the container 22 approaches the front rollers 36A and 36B by the second belt conveyor 28 as shown in FIGS. 9C and 9D.

  Next, as shown in FIG. 9E, the controller 31 detects the upper front roller at the timing when the container 22 is detected by the second sensor 42, that is, at the timing when the front end in the transport direction of the container 22 contacts the front rollers 36A and 36B. 36A and the lower front roller 36B are moved laterally in the direction of arrow G while being moved vertically in the direction of the arrow E to be separated. At the same time, the upper rear roller 38A and the lower rear roller 38B are vertically moved in the direction of the arrow E that separates them.

  10A and 10B, the panorama label 3A is affixed to the front and back surfaces of the container 22, and the open / close side of the container 22 is sealed with the panorama label 3A.

  In the present embodiment, the panorama label 3A is used as the double-sided printing label, and the example in which the operation of attaching the panorama label 3A to the front and back surfaces of the container 22 and the operation of sealing the container 22 are performed simultaneously. However, when the double-sided printing label is pasted by the pasting device 20 on the front and back surfaces of the container 22 previously sealed by a sealing member such as a rubber band or a tape or heat welding so that the lid 22B is not opened, the second The container 22 may be placed on the belt conveyor 28. That is, the pressing means 26 and the transfer means 30 are not necessary. Further, it is not necessary to use the panorama label 3A as the double-sided printing label, and a normal double-sided printing label in which the front surface label X and the back surface label Y are separated can be used.

  As described above, the sticking device for the double-sided printer according to the present invention can stick the double-sided label on the front and back surfaces of the adherend at the same time. Labor can be reduced. If a panoramic label is used as the double-sided printing label, the container can be sealed at the same time.
