Description

  The present invention relates to an information mounting sheet manufacturing apparatus for attaching a predetermined number of single sheet such as each RFID called an inlet separated from an information mounting source sheet onto a continuous sheet.

  In recent years, RFID media that include an IC module and an antenna and can exchange data in a non-contact manner are becoming cheaper and used as labels in addition to IC cards. When shipping as a sheet with a large number of RFID labels such as inlets attached, it is basically necessary for the inlets to be all non-defective, and maintaining quality during mass production due to high-speed manufacturing. Improvement in yield is desired.

  Conventionally, when manufacturing an RFID label sheet, for example, Patent Documents 1 and 2 disclose that an inlet to be affixed eliminates defective products and makes them all good. In Patent Documents 1 and 2, each inlet on the manufactured RFID label original sheet is sequentially inspected for communication, and only a non-defective IC label determined to be non-defective according to the communication state is coated with an adhesive by an inlet mounting machine ( It is disclosed as an apparatus for sequentially sticking onto a release paper.

  In order to mass-produce the inlet mounting machine as described above, for example, as shown in Patent Documents 1 and 2, for example, four suction arms are rotated, and each non-defective inlet is sucked to each suction arm. When the corresponding arm is positioned on the mount on which the adhesive is applied by the rotation, the adsorbing portion of the arm is protruded by the cylinder and stuck on the mount surface. In this case, the inlet to be affixed has the same arrangement as the RFID label original sheet, and the inlet determined to be defective is excluded, so the so-called tooth missing state in which the inlet portion of the defective product is removed. Becomes an array of

  In other words, each arm that attaches the inlet onto the mount is provided with a suction portion that sucks the inlet at the tip, and the tip portion protrudes on the mount when a good inlet is sucked and is determined to be a defective inlet. When the inlet is not attracted, cylinder control is performed so that the inlet does not protrude.

  FIG. 6 shows an explanatory diagram of a conventional inlet sticking state. An inlet mounting machine 101 in FIG. 6A is described in Patent Documents 1 and 2 described above. The inlet mounting machine 101 is configured to mount the inlet 111 at a predetermined pitch on a mount 102 to which an adhesive is applied. Four suction arms 104A to 104D are provided at 103 at an equal interval so as to be slidably movable. The tips of the suction arms 104A to 104D serve as suction holding portions.

  In the inlet loading machine 101, the rotation speed is slowed down when the inlet 111 is first held, the rotation is accelerated to the loading position, and the rotation is synchronized with the transport speed of the mounting sheet 102 when loaded on the mounting sheet 102. The acceleration / deceleration is repeated to reduce the speed. Such an inlet mounting machine 101 is effective in that the mounting pitch of the inlets 111 mounted on the mount 102 can be changed and mounted on the mount 102, but the rotation is accelerated / decelerated. In order to synchronize with the conveyance speed of the mount 102, the mounting pitch is accurately adjusted, as shown in FIG. 6A, the tip of the inlet 111 (the tip on the downstream side in the mount conveyance direction) is attached to the suction arms 104A to 104A. It is necessary to hold at 104D.

  However, when the suction arm 104A to 104D holds and rotates the tip of the inlet 111 and mounts it on the mount 102, the rear end portion of the inlet 111 bends due to the deceleration acceleration as shown in FIG. In this state, if it is to be mounted on the mount 102, as shown in FIG. 6C, the rear end side of the inlet 111 adheres to the mount 102 earlier than the front end side and remains bent. Will be installed. If the surface sheet is covered in this state, the inlet 111 becomes wrinkled, which causes a problem of quality deterioration.

  Accordingly, the present invention has been made in view of the above problems, and provides an information-mounted sheet manufacturing apparatus that prevents wrinkling of a single-piece sheet affixed on a continuous sheet, maintains quality, and improves yield. Objective.

In order to solve the above-mentioned problem, in the invention of claim 1, it is an information mounting sheet manufacturing apparatus for sticking a single piece sheet at a predetermined interval onto a conveyed continuous sheet as a label, and a predetermined number of rotated sheets. Single-piece sheet affixing having a sticking arm, holding the supplied single-piece sheet at the tip in the rotation direction, and sticking the single-piece sheet rotated and held to the sticking position on the continuous sheet on the continuous sheet And a continuous sheet transport that places a pasting position roller with the pasting position at the apex at the pasting position in the transport path of the continuous sheet and guides the upstream side of the continuous sheet pasting position from below to the pasting position. And a path defining means.

  According to a second aspect of the present invention, the continuous sheet conveyance path defining means conveys the continuous sheet substantially horizontally on the downstream side of the sticking position.

  According to the first aspect of the present invention, the single sheet supplied by a predetermined number of the rotation arms rotated in the single sheet application portion is held at the tip portion in the rotation direction and rotated to the application position on the continuous sheet. A single piece sheet held on the continuous sheet is pasted on the continuous sheet, and a pasting position roller having the pasting position as a substantially apex is arranged at the pasting position in the continuous sheet conveyance path, and the continuous sheet is attached to the pasting position. By adopting a configuration that guides the upstream side from the lower side to the pasting position, the bending portion behind the single piece sheet when sticking with the single piece sheet tip is held on the upstream side of the continuous sheet conveyance at the pasting position and the conveyance path from below. Will contact the continuous sheet later than the leading edge, preventing the generation of wrinkles on the single sheet affixed on the continuous sheet and improving the quality and yield. It is intended.

  According to the invention of claim 2, the continuous sheet is transported substantially horizontally downstream of the pasting position, whereby the bent portion is regulated to be in a substantially horizontal state after being pasted on the continuous sheet at the leading end portion of the single piece sheet. Therefore, it is possible to prevent the jumping behavior of the rear part once bonded, and thus the generation of wrinkles on the single piece sheet stuck on the continuous sheet can be prevented, and the quality can be maintained and the yield can be improved. is there.

It is explanatory drawing which shows the relationship between the rotation arm group and the sticking position roller in the inlet sticking mechanism of FIG. It is operation | movement explanatory drawing (1) of the inlet sticking of FIG. It is operation | movement explanatory drawing (2) of the inlet sticking of FIG. It is explanatory drawing of the conventional inlet sticking state.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, the schematic block diagram of the information mounting sheet manufacturing apparatus which concerns on this invention is shown. In the present embodiment, the case where RFID label sheets having the same arrangement are produced from six rows of RFID label original sheets is shown, but even one row can be applied, and two or more rows are produced. It can be applied to things. In this embodiment, a single sheet is described as an RFID inlet, and a continuous sheet is described as a continuous mount.

  FIG. 1A shows a conceptual diagram of an information mounting sheet manufacturing apparatus. The information mounting sheet manufacturing apparatus 11 is conveyed from a continuous RFID label original sheet 12 in a roll form by, for example, feed rollers 13A and 13B. The As shown in FIG. 1B, the RFID label original sheet 12 is obtained by forming inlets 41, which are RFIDs, in six rows on a sheet base material 42 at predetermined intervals.

  An RFID reading inspection unit 14 is arranged between the feed rollers 13A and 13B, and each inlet 41 on the RFID label original sheet 12 is simultaneously read and inspected in six rows and one stage to determine whether it is a non-defective product or a defective product. The result is sent to the control unit (17) described later. The RFID label original sheet 12 is sent to the unit inlet cutting unit 15 after the inspection. The unit inlet cutting unit 15 is composed of an inlet cutting upper blade 21 and an inlet cutting lower blade 22, and is made into an inlet 41 by rotating cutting simultaneously in six rows and one stage. The inlet cutting lower blade 22 is a mechanism for sucking and holding the inlets 41 individually.

  For the inlet 41 after cutting, the controller 17 controls the suction of the inlet cutting lower blade 22 based on information on whether the corresponding inlet 41 is a non-defective product or a defective product, and only the non-defective inlet is sucked and held. In the case of the inlet 41 determined as a defective product, the defective inlet collection unit 23 collects the inlet 41 without sucking and holding it.

  The inlet 41 sucked and held by the inlet cutting lower blade 22 is transferred to the unit inlet feeding roller 31 of the inlet pasting portion 16 by the rotation of the inlet cutting lower blade 22. The unit inlet feed roller 31 is also a mechanism for sucking and holding the inlet 41 in the same arrangement as the unit inlet cutting unit 15, and the sucked and held inlet 41 is supplied to the inlet pasting mechanism 32 by rotational conveyance. The unit inlet feed roller 31 and the inlet sticking mechanism 32 constitute an inlet sticking part 16 that is a single piece sheet sticking part. The configuration up to this point is the same as that of Patent Documents 1 and 2 described above.

  The inlet sticking mechanism 32 will be described in detail with reference to FIG. 2. The inlet sticking mechanism 32 includes a rotating arm group, an inlet suction mechanism, and an air cylinder drive transmission unit, and is provided with individual inlets supplied from the unit inlet feed roller 31. 41 is pasted on the continuous mount 20 in the same arrangement as the RFID label original sheet 12.

  Two types of air, positive pressure and negative pressure, are supplied as control air from the air supply source 18 to the inlet pasting mechanism 32 via the air control drive unit 19. The air supply timing is controlled by the controller 17. Here, the control unit 17 controls the information mounting label sheet manufacturing apparatus 11 in an integrated manner. In particular, the position information in each inlet from the RFID reading inspection unit 14 and the inspection determination result of a good product or a defective product. And the air control drive unit 19 that controls the suction holding and holding of the non-defective inlet by the inlet cutting lower blade 22 and the sticking onto the mount 20 by the inlet sticking mechanism 32 is controlled. Although not shown, the air control drive unit 19 includes respective electromagnetic valves that supply and drive control air to an air cylinder drive transmission unit (54) described later.

  The mount 20 is formed with a release agent, and an adhesive is applied onto the release agent of the mount 20. As shown in FIG. 1B, the same arrangement as that of the RFID label original sheet 12 is provided by the inlet pasting mechanism 32. Only the inlet 41 determined to be non-defective is attached. In this case, the position of the inlet 41 determined as a defective product is in a so-called tooth missing state. That is, the affixed inlet 41 becomes an RFID label holding an adhesive, and is temporarily attached to the mount 20 with a release agent. Here, the case where the adhesive is applied to the mount 20 will be described, but conversely, the adhesive may be applied to the inlet side. In short, the adhesive is applied to either the inlet 41 or the mount 20. It is good.

  The mount 20 is supplied in the form of a roll (not shown), and is temporarily passed downward from the horizontal state to the mount transport path path rollers 33 and 34, and is lifted upward from below with respect to the sticking position roller 35 to be substantially horizontal. A conveyance path is formed on the surface. The board conveyance path defining means includes the board conveyance path path rollers 33 and 34 and the sticking position roller 35. The relationship between the rotating arm and the application position roller in the inlet application mechanism will be described with reference to FIG.

  Here, the schematic block diagram of the inlet sticking mechanism of FIG. 1 is shown in FIG. The configuration and operation of the inlet pasting mechanism shown in FIG. 2 are the same as Japanese Patent Application No. 2011-092513 filed by the present applicant. That is, FIG. 2A shows a conceptual diagram of the inlet sticking mechanism 32, and is configured by connecting a rotary arm group 52, an inlet suction mechanism 53, and an air cylinder drive transmission unit 54 to a rotary shaft 51. The air cylinder drive transmission unit 54 includes an air transmission outer ring portion 55 and an air transmission inner ring portion 56. The rotation arm group 52, the inlet suction mechanism 53, and the air transmission outer ring portion 55 of the air cylinder drive transmission portion 54 rotate together with the rotation of the rotation shaft 51, and the air transmission inner ring portion 56 of the air cylinder drive transmission portion 54 is fixed to be non-rotating. State.

  In the rotating arm group 52, six rotating arms 52 </ b> A to 52 </ b> F are arranged at the same interval as the inlet arrangement in accordance with the six rows of the RFID label original sheet 12. Incidentally, when the RFID label original sheet 12 is in one row, it becomes one rotating arm 52. Taking one rotating arm 52A as an example, as shown in FIGS. 2B and 2C, three sticking arms 62 (62A to 62C) extend from the center of rotation at the same interval, and sticking arms 62A to 62A to A movable shaft 63 serving as a cylinder is included in each of 62C, and a movable tip 61 (61A to 61C) is integrally formed at the tip of the movable shaft 63.

  That is, each of the sticking arms 62A to 62C protrudes (positive pressure) and does not protrude (negative pressure as a pull-in) the movable tip portions 61A to 61C, which are tip portions of the rotating arm 52A, according to the driving of the air cylinder drive transmission portion 54. ), When the non-defective inlet 41 is supplied, the movable tip portions 61A to 61C, which are the tip portions, are protruded and adsorbed, and when they are positioned on the mount 20 by rotation, The movable tip portions 61A to 61C that are the tip portions are projected and pasted, and when the inlet 41 is not supplied for defective products, the movable tip portions 61A to 61C that are the tip portions are not projected so as not to contact the mount 20. It is something to be made.

  Further, as shown in FIG. 2C, the movable tip portions 61A to 61C have two inlet suction protrusions (one of which does not appear in the drawing) on the inlet holding surface 64 when the movable portion tip portion 61A is taken as an example. 65, and the inlet suction hole 65A communicates with the inlet holding air supply port 66 through the internal vent hole. The inlet holding air supply port 66 is connected in communication with the inlet suction mechanism 53. The inlet suction mechanism 53 supplies negative pressure air for adsorbing the inlet 41 into the inlet suction holes 65A of the movable tip portions 61A to 61C of the sticking arms 62A to 62C.

  On the other hand, a space region for moving the movable shaft 63 forward and backward is formed in the sticking arm 62A including the movable shaft 63 integral with the movable tip portions 61A to 61C, and a regulation protrusion for regulating the position of the movable shaft 63 at an appropriate position. Is formed. A driving air supply port 67 is formed in the space area, and is connected to a connection port formed in the air transmission outer ring portion 55 of the air cylinder drive transmission portion 54 via an air joint 57A.

  By the way, if the number of the sticking arms is three or more, the effect of the present invention can be obtained, and when the arrangements are equally spaced, the number can be realized by a multiple of three. Moreover, when it is set as the number other than the multiple of 3, it can implement | achieve by not arrange | positioning another sticking arm in the point symmetrical position of one sticking arm.

  Next, FIG. 3 shows an explanatory diagram of the relationship between the rotating arm group and the sticking position roller in the inlet sticking mechanism of FIG. In FIG. 3, for example, when a position just below the center of the rotating arm 52 </ b> A is a pasting position 52 </ b> P (P on the mount 20), the center of the pasting position roller 35 is positioned on the center line. In this case, the diameter of the sticking position roller 35 is preferably equal to or less than the diameter of the rotating arm 52 (the diameter of the protruding state). And it arrange | positions so that the vertex 35P of the sticking position roller 35 may become the substantially sticking position P on the mount 20. Here, the substantially pasting position is meant to include the case where the apex position is displaced from the pasting position within the allowable error range.

  At this time, the transport path of the mount 20 is in a state where the upstream side with respect to the pasting position P is guided to the pasting position P from below. Further, the downstream side of the mounting position P of the mount 20 is a substantially horizontal conveyance path. Here, “substantially horizontal” means that an inclination which is equivalent in terms of action is included as an allowable error.

  FIG. 4 and FIG. 5 are diagrams for explaining the operation of attaching the inlet of FIG. First, the rotary arm group 52 (here, only one rotary arm 52A is shown and described, but the same operation is performed because the other rotary arms 52B to 52F are connected), and each of the pasting arms 62A to 62C. However, at the holding position of the inlet 41, the rotation speed is controlled to be slow (deceleration), and is rotated at a high speed from the holding position to immediately before the application position, and at the application position, the rotation speed is decelerated to a rotation speed synchronized with the conveyance speed of the mount 20 and applied. From the position to the position immediately before holding is controlled by acceleration / deceleration that is rotated at high speed. Even when the inlet 41 is a defective product and is not held, acceleration / deceleration is controlled according to each position.

  In FIG. 4A, when a good inlet 41 is supplied, positive control air is supplied to the drive air supply port 67 of the sticking arm 62A in the previous stage of the supply position (position immediately before holding). As a result, the movable shaft 63 protrudes, and the tip portion of the inlet 41 is sucked and held by the inlet suction portion 65 (inlet suction hole 65A) of the movable tip portion 61A. At this time, the rotating arm 52A is decelerated. After the inlet 41 is held by the sticking arm 62A, the rotary arm 52A is accelerated and rotated at a high speed until the sticking arm 62C reaches a position immediately before sticking, and the sticking arm 62C is rotated at a reduced speed from the position immediately before sticking. When the inlet 41 is not held, the movable shaft 63 is pulled in by control air (negative pressure). Then, from the sticking position of the sticking arm 62C, the rotating arm 52A is accelerated and rotated at a high speed until the sticking arm 62B reaches a position immediately before holding the inlet 41, and the sticking arm 62B is rotated at a reduced speed from the position immediately before holding. The leading end portion of the non-defective inlet 41 is sucked and held by the control air.

  Subsequently, as shown in FIG. 4B, the rotating arm 52A is accelerated and rotated at a high speed until the sticking arm 62A reaches a position immediately before sticking, and is decelerated to synchronize with the mount conveyance speed to the sticking position of the sticking arm 62A. Rotation.

  At this time, since the rotation speed is decelerated so that the pasting arm 62A reaches the pasting position on the mount 20 (immediately before the pasting), the inlet 41 is moved backward in the rotation direction by the deceleration acceleration. The part will bend downward. When the sticking arm 62A (movable tip 61A) reaches the sticking position, the upstream side of the sticking position of the mount 20 is transported from below as shown in FIG. When the leading end portion is in contact with the mount 20, the back portion is not in contact with the mount 20 even if the rear portion is bent downward.

  The mount 20 is transported substantially horizontally on the downstream side of the pasting position, and the inlet 41 gradually takes a contact state on the mount 20 from the state of FIG. As shown to (A), bending will be normalized (leveled) and it will affix on the said mount 20 with the whole sticking surface of the inlet 41. FIG. After sticking by the sticking arm 62A, the rotary arm 52A is controlled at high speed rotation until the sticking arm 62C reaches a position immediately before holding the inlet 41, and is controlled by decelerating rotation from the position immediately before holding the sticking arm 62C to the holding position. If the inlet 41 is not held due to a defective product at the holding position of the sticking arm 62C, the rotary arm 52A is controlled at a high speed until the sticking arm 62B comes to a position immediately before sticking. Subsequently, as shown in FIG. 5B, the rotary arm 52A is decelerated and rotated until the sticking arm 62B reaches the sticking position from the position immediately before sticking, but the deflection is also normalized in the inlet 41 held at the tip (horizontal). And the entire sticking surface of the inlet 41 is stuck on the mount 20. Then, as shown in FIG. 4A and after, the rotation control of the rotation arm 52A and the suction holding and non-holding operations of the inlet 41 in each of the pasting arms 62A to 62C are performed.

  In this way, the bent portion behind the inlet 41 when sticking by holding the inlet tip is gradually brought into contact with the mount 20 as the transport path from the lower side on the upstream side of the board transport at the pasting position later than the tip portion. Thus, even if sheets are further overlapped on the mount 20, no wrinkles are generated in the attached inlet 41, and the quality can be maintained and the yield can be improved.

  Further, since the mount 20 is transported substantially horizontally on the downstream side of the sticking position, the rear bent portion is restricted to a substantially horizontal state after sticking the tip portion of the inlet 41 to the mount 20, and thus once bonded. As a result, it is possible to prevent the occurrence of wrinkling of the inlet 41 affixed on the mount 20 in the same manner as described above, and to maintain the quality and improve the yield. is there.

  The information mounting sheet manufacturing apparatus of the present invention can be used in the industrial field of information mounting sheet manufacturing in which a predetermined number of single-sheets such as inlets separated from a label original sheet are pasted onto a continuous sheet.
