Description

  The present invention relates to an apparatus for attaching a permission seal such as a copyright on a transfer line for transferring a work such as a gaming machine or a gaming machine part.

  Conventionally, game machines completed through assembly work are shipped to pachinko halls, etc. with a sticker such as a product number, model code, license for association or association use attached by each manufacturer. (For example, Patent Document 1).

  With respect to the place where the stamp is pasted, it is required to be pasted at a position that can be seen by the player due to revisions of various industry rules and the like. ).

  By the way, recently, it has become necessary to affix a license sticker for copyrights (music copyrights, etc.) of music used for game effects. The currently issued copyright permission seal is provided in the form of a sheet carrying, for example, 100 seals arranged in 10 rows and 10 columns. This copyright permission sticker has a large unit price, so it becomes a big problem if a sticking failure occurs.

  For this reason, in the sticker sticking device for sticking the copyright permission sticker, “(1) Technology for taking out only one sheet from many sheets prepared by stacking”, “(2) n × m (n , M is an integer greater than or equal to 2) Technology that peels only one seal from among the seals ”,“ (3) Before sticking so that the seal does not tilt significantly with respect to the sheet sticking position of the workpiece Position adjustment technology "is required.

Among these necessary techniques, the following proposals have conventionally been proposed as “a technique for extracting only one sheet from a large number of stacked sheets”.
1) A method in which two suction pads that can be moved up and down are provided, one side of the sheet is lifted while holding the sheet group while the other is lifted, and the sheet is bent and separated (Patent Document 3).
2) Equipped with two suction pads extending in the shape of a letter C on the left and right and a suction pad extending vertically in the center, while holding the sheet group at the center, raise the left and right suction pads diagonally upward to bend the sheet (Patent Document 4).
3) A method comprising two suction pads and air nozzles that can swing, and separating them by swinging operation of the suction pads and air ejection of the air nozzles (Patent Document 5).
4) Stick a hook-and-loop fastener with fine protrusions on a leaf spring attached to the opening of the magazine that stores the sheets, and separate the fine protrusions of the hook-and-loop fasteners when the sheet is lifted by the suction pad. Method (Patent Document 6).

  In addition, regarding the “technology for removing the seal from the mount”, a method has been proposed in which the mount is bent at an acute angle and the seal is lifted off from the mount (Patent Document 7).

Furthermore, as “a technique for sticking a seal to a workpiece without tilting”, a method of adjusting an angle by pushing a seal that is sucked by a suction pad with a guide plate has been proposed (Patent Document 8).
Japanese Patent Laying-Open No. 2003-260170 (FIG. 4) Japanese Utility Model Publication No. 7-9377 (FIG. 1) JP-A-8-2712 (FIG. 2) Japanese Patent Laid-Open No. 6-179535 (FIG. 1) JP-A-8-290843 (FIG. 3) Japanese Patent Laid-Open No. 6-255821 (FIG. 11) Japanese Patent Laying-Open No. 2003-175922 (FIG. 10) JP 2002-2647 A (FIGS. 6 and 7)

  However, since the methods of Patent Documents 3 and 4 cause the sheet to be greatly bent or curved, there is a risk that the expensive copyright permit seal that is detachably attached to the sheet may be displaced or peeled off.

  In the method of Patent Document 5, the copyright permission seal may be peeled off while repeating the swinging motion, or the second sheet may be displaced and land due to air blowing. When the second sheet is shifted and landed, there is a possibility that the sheet cannot be placed at the correct application position when the sheet is adsorbed and moved to the application position. In this case, there is a possibility that the seal is not correctly peeled off in the seal peeling process for the next sticking, and that the seal cannot be stuck at the correct position in the sticking process.

  Furthermore, in the method of Patent Document 6, the leaf spring bent inward becomes an obstacle when the sheet is stored in the magazine, and the edge of the sheet is hooked up and the edge of the seal on the upper surface of the sheet is turned up. There is also a possibility that adhesion between sheets may occur due to the edge of the seal.

  Further, since the copyright permission sticker issued by the Music Copyright Association is 10 × 10 = 100 sheets arranged and carried on one sheet, in the method of Patent Document 7, ten sheets are peeled off at the same time. It will end up.

  Furthermore, the method of Patent Document 8 has a problem that when the suction force is strong, the seal is bent when pressed by the guide plate, while the suction force is too weak, as explained in the prior art. Further, there is a problem that further deviation occurs after the position adjustment with the guide plate.

  In the present invention, among these problems that cannot be solved by the prior art, in particular, a large number of sheets bearing a permission seal such as a copyright are detachably supported on the upper surface, and a number of sheets are peeled off. It is an object of the present invention to provide a technique for taking out only one sheet without causing waste of a seal.

The seal sticking device of the present invention made to achieve the above object is installed at a permission seal sticking work position set in the middle of a transport line for transporting workpieces, and seals a predetermined position of the transported workpiece. A sticker sticking device for sticking a permission sticker as a sticking position, characterized in that it has the following configuration.
(1) A sheet placement holding unit for preparing and stacking rectangular sheets carrying nxm (n and m are integers of 2 or more) of the above permission seals and detachably supported with the seals facing up. Be prepared.
(2) It is provided with sheet transfer means for adsorbing the rectangular sheets prepared by being stacked on the sheet placement holding unit from above, taking them one by one and transferring them to the seal peeling operation unit.
(3) It is provided with a seal peeling means that is installed in the seal peeling working unit and sucks and removes the permission seals carried on the upper surface of the rectangular sheet one by one.
(4) It has a sticking means for moving and sticking the permission seal peeled off by the seal peeling means to the seal sticking position of the workpiece on the transport line.
(1-1) A plurality of guide pins are erected on the sheet placement holder so that at least one of the four sides of the rectangular sheet is in contact with each other.
(2-1) The sheet transfer means includes a plurality of transfer suction pads provided so as to be swingable between a state where the sheet is suspended in a vertical direction and a state where the sheet is inclined.
(2-2) The upper surface of the uppermost one of the rectangular sheets stacked on the sheet placement holding unit in a state of hanging down in the vertical direction is sucked to the plurality of transfer suction pads, and the suction is performed. The raised rectangular sheet is raised until it is above the tip of the guide pin, and then the swinging motion is performed several times to swing between the vertically suspended state and the inclined state, and then again. A sheet take-out operation control means for executing an operation of returning to the state of hanging vertically.

  According to the sticker sticking device of the present invention having such a configuration, even when two rectangular sheets are lifted by overlapping, the sheet take-out operation control means performs the swinging motion several times, so that the lower one is shaken. Can be dropped. At this time, even if the rectangular sheet that has been shaken down is tilted when falling down and does not fall straight, it is guided by the guide pins and correctly returned to its original position. Even if the suction pad does not return correctly and is slightly caught by the guide pin, when the suction pad is once lowered in the next suction operation, it is returned to the correct position where the four sides are guided by the guide pin and sucked.

  Therefore, according to the seal sticking device of the present invention, the rectangular sheet is not always taken out one by one, but is always delivered to the next seal peeling working unit in a properly aligned state. Can do. As a result, it is possible to prevent the two permission seals from being accidentally peeled off in the subsequent seal peeling operation.

The seal sticking device of the present invention may further include the following configuration.
(1-2) The plurality of guide pins are erected in the vicinity of the corners of each side so that the corners of the rectangular sheet can be positioned.

  By providing such a configuration, the corners of the rectangular sheet can be positioned. Therefore, even if the positioning accuracy by the guide pins is slightly loosened to facilitate the setting of the rectangular sheet, the positioning can be performed firmly. Note that the tip of the guide pin is preferably rounded.

The seal sticking device of the present invention may further include the following configuration.
(1-3) The plurality of guide pins are planted with brush-like projections having a length that reaches only marginal margins of the rectangular sheet.

  By adopting such a configuration, the rectangular sheet is naturally separated by touching the brush-like projections when setting the rectangular sheet, and the edge of the sheet is also attached to the brush-like projections when lifting with the suction pad. The sheet is separated by contacting. Therefore, the possibility that two or more sheets are lifted by mistake can be reduced. As a result, the movement of the suction pad in the swinging operation may be very small, and the seal can be prevented from being bent during the swinging operation.

The seal sticking device of the present invention may further include the following configuration.
(2-3) Each of the plurality of transfer suction pads is configured to be able to swing independently.

By adopting this configuration as well, for example, the sheet take-out operation control means can be used for a plurality of suction pads for transfer.
1) Either one of them is swung in an inclined state, and the other is left in a suspended state.
2) All swing to tilt in the same direction.
3) Swing so as to incline in the direction in which the tips approach each other.
4) Swing so as to incline in directions in which the tips are separated from each other.
Apply vibration to bend various parts of a rectangular sheet in various states, such as a state where the center of the sheet is convex upward, a state where the sheet is convex downward, or a state where one end of the sheet is lifted up. Can do.

  Here, in the sheet carrying a licensed seal of n × m (n, m is an integer of 2 or more) sheets of copyright on the upper surface in a matrix form, in addition to the overall adhesion due to static electricity, There is a case where the seal sticks between the seals due to the influence of the adhesive. On the other hand, since the structure of (2-3) is also provided, it is possible to make a deformation such that the position close to the edge as well as the center of the sheet is the apex of the curve. By closely deforming the portion between the seals, it is possible to cope with close contact due to the influence of the adhesive or the like. Since the apexes of the curve can be formed in various parts in this way, it is not necessary to form a large curve state for the entire sheet. As a result, the entire sheet is greatly curved and the peelable sticker is not shifted or turned up.

It should be noted that the seal sticking device of the present invention is also provided with the following configuration, and among the problems that cannot be solved by the prior art, in particular, n × m (n and m are integers of 2 or more) copies. It is possible to prevent the waste of the seal from being generated by accurately removing only one permission seal from the sheet carrying the permission seal such as detachable on the upper surface.
(2-11) The sheet transfer means includes a plurality of transfer suction pads, each of which performs suction / release independently, with a plurality of transfer suction pads from the sheet placement holding unit. It is comprised as a means to convey the rectangular sheet picked up and taken out to near the seal peeling work part.
(3-11) The seal peeling means includes a table portion on which the rectangular sheet is placed, a feeding roller that feeds the tip of the rectangular sheet between the table portion near the edge of the table portion, and the feeding roller. A push-bending member that pushes and bends the front end of the rectangular sheet protruding from the edge of the table portion by the roller; and a vertical pull-out member that grips and pulls the front end of the rectangular sheet that is pushed and bent downward by the push-bending member. , A horizontal support member that can move forward and backward toward the edge of the table portion, a peeling suction pad having a suction surface that can suck only one permission seal on the rectangular sheet, and more than the peeling suction pad A separation pressing member provided so as to be positioned on the feeding roller side.
(3-12) For the plurality of transfer suction pads that have transferred the rectangular sheet to the vicinity of the seal peeling portion, the transfer suction pad on the front side of the rectangular sheet is opened, and then the transfer is performed on the rear end side of the rectangular sheet. Sheet opening operation control means for releasing the transfer suction pad on the rear end side after moving the suction pad toward the edge of the table portion;
(3-13) After the feeding roller is rotated in the sheet feeding direction, the pushing / bending member is lowered, the horizontal support member is moved toward the edge of the table portion, and further the vertical movement is performed. A seal floating operation control means for performing a seal floating operation for floating the permission seal from the rectangular sheet by causing the drawing member to perform a gripping and lowering operation is provided.
(3-14) Among the permission seals in a state of floating on the horizontal support member, the seal located at the end in the seal alignment direction on the most distal end side is adsorbed by the peeling pad and the seal adjacent to the flange A peeling operation control means for performing a seal peeling operation for raising the peeling suction pad after the peeling pressing member is brought into contact with an upper surface;

Here, “the seal positioned at the end in the seal arrangement direction on the most distal side” means “the seal positioned at the end of the row” when no seal in the top row is used. When several sheets are already used, it means “seal located at the end of the remaining seals” in the top row.
According to the sticker sticking apparatus of the present invention having such a configuration, when the rectangular sheet is transferred to the vicinity of the seal peeling work part by the sheet transfer means, the sheet opening operation control means is activated. Accordingly, the transfer suction pad on the front side of the rectangular sheet among the plurality of transfer suction pads is opened, and the sheet front end hangs downward. At this time, the opening operation may be performed at such a height that the front end of the sheet comes into contact with the table portion. After the opening operation of the transfer suction pad on the front end side of the sheet, the sheet release operation control means moves the transfer suction pad on the rear end side of the sheet toward the edge of the table portion and then releases it. Accordingly, the leading edge of the rectangular sheet is placed on the table portion in a state of being sandwiched between the feeding roller and the table portion. At this time, if the position at which the leading end of the sheet comes into contact with the feeding roller is set to the stop and release position of the trailing suction pad, the leading end of the sheet and the table edge are naturally adjusted to be parallel.

  Subsequently, the seal floating operation control means is operated, and the feeding roller is rotated in the sheet feeding direction. Thereby, the front-end | tip of a rectangular sheet protrudes from the edge of a table part. Thus, at the timing when the leading end of the rectangular sheet protrudes from the edge of the table portion, the pushing and bending member is lowered. As a result, the protruding end of the rectangular sheet is pushed and bent downward. The front end of the rectangular sheet pushed and bent in this way is bent substantially at a right angle by the horizontal support member being brought closer to the edge of the table portion. And the front-end | tip of the rectangular sheet | seat bent at right angle is hold | gripped by the perpendicular | vertical drawer member, and is pulled below. At this time, the feeding speed of the feeding roller and the lowering speed of the vertical drawing member are synchronized so as to be substantially the same. In this way, the rectangular sheet is bent downward at a substantially right angle and pulled down, so that the permission seal on the upper surface rises. At this time, since the horizontal support member is approached toward the edge of the table portion, the lifted permission seal is received in a sure manner. As a result, the permission seal advances on the upper surface of the horizontal support member while being lifted from the rectangular sheet.

  When the permission seals thus lifted from the rectangular sheet are moved onto the horizontal support member in a state where at least two permission seals (excluding the rear end of the sheet) are arranged in the feeding direction, the peeling operation control means is activated. As a result, the holding member for peeling causes the seal located at the end of the seal alignment direction on the most distal end side among the permission seals on the horizontal support member to be sucked by the peeling suction pad and peeled to the upper surface of the seal adjacent to the flange. After the pressing member is brought into contact, the peeling suction pad is raised. Thereby, only one sheet from the edge of the sheet can be peeled off.

The seal sticking apparatus provided with the configurations (2-11) and (3-11) to (3-14) may further include the following configuration.
(3-15) The horizontal support member is provided with a blade having a taper surface at the tip.

  By providing such a configuration as well, the permission seal floating from the rectangular sheet can be smoothly received by the horizontal support member by scooping it up with a blade.

The seal sticking apparatus provided with the configurations (2-11) and (3-11) to (3-14) may further include the following configuration.
(3-16) The peeling operation control means includes a peeling start position setting means for setting a peeling start position at which peeling of the permission seal is to be started, and the seal peeling operation with respect to a seal arranged next to the first peeled seal. Is repeatedly executed over one row that is fed out at the head, and when the permission seal is peeled from the end of the first row by the repeated execution means, the feeding roller and the vertical pulling member A peeling resumption position setting means for causing the sheet feeding operation to be executed for one sheet of the seal length and setting the seal at either end of the next row to the peeling start position;

  According to the seal affixing device having such a configuration, the peeling start position can be set by the peeling start position setting means, and the repeated execution means peels off one row of seals fed out to the head in order from the end. When all of the permission seals for one row have been peeled off, the peeling resumption position setting means resets the feeding of the rectangular sheet and either end of the next row as the peeling start position. For example, 10 × 10 = 100 sheets When using a new rectangular sheet carrying the permission seal, set the left or right end of the top row as the peeling start position, and remove all 100 sheets in order from the first sheet. Can do. Further, the peeling start position setting means sets the above-mentioned position as a default, and makes it possible to set an arbitrary position as necessary, so that the permission seal is used halfway from a non-new rectangular sheet. The permission seal can be peeled off and used without any loss.

  It should be noted that this peeling start position setting means is easy to operate if it is configured as “a means for associating the application position of the n × n permission seal as a unique position on the rectangular sheet and designating the unique position”. .

The seal sticking apparatus provided with the configurations (2-11) and (3-11) to (3-14) may further include the following configuration.
(4-11) The sticking means includes a sticking suction pad that receives the permission seal transferred by the peeling suction pad and performs a sticking operation on the workpiece.

  By having such a configuration as well, the peeling operation and the sticking operation are executed by separate suction pads, so the moving distance of the suction pad can be shortened, the return time of the peeling suction pad can be shortened, and from peeling to sticking The time required for the operation can be reduced as a whole.

In addition, when the sticker sticking device of the present invention further comprises the following configuration, among the problems that cannot be solved by the prior art, in particular, position adjustment for sticking a permission sticker such as a copyright right at the correct position. It is possible to prevent wasteful seals by reliably executing the above.
(3-21) The seal peeling means includes a peeling suction pad for moving and releasing the permission seal peeled off by suction in the seal peeling working unit to a delivery position to the sticking means.
(4-21) The sticking means includes a sticking suction pad that receives the permission seal transferred to the delivery position by the peeling suction pad and performs a sticking operation on the workpiece.
(4-22) The delivery position includes a seal placement surface formed within a length and a width of the permission seal by a plurality of thin protrusions, and at least perpendicular to the seal placement surface in the horizontal direction. An orthogonal horizontal guide member that approaches and separates from two directions is provided.
(4-23) After the permission seal is placed at the delivery position, the orthogonal horizontal guide member is moved away from the center of the seal placement surface by a half of the length of the permission seal or a half of the width. Position adjustment operation control means to be approached.

  According to the seal sticking device having the configurations of (3-21) and (4-21) to (4-23), the permission stickers are transferred one by one to the delivery position by the peeling suction pad, and the sticking thereafter Since the sticking suction pad takes charge, the cycle time of the peeling operation can be shortened, and the time required for the whole sticking work can be shortened. Further, since the seal placement surface is configured as described above by the tips of a large number of thin protrusions, the permission seal placed at the delivery position does not stick firmly to the seal placement surface. As a result, when the orthogonal horizontal guide member comes into contact, the position and angle of the permission seal are adjusted. At this time, since the position adjustment operation control means operates the orthogonal horizontal guide member as described above, the center of the permission seal coincides with the center of the seal placement surface. In addition, since this position adjustment operation is performed from the orthogonal direction, the four sides of the seal coincide with the respective directions of the orthogonal horizontal guide, and if it is applied to the workpiece as it is, it can be applied to the workpiece without being inclined. Become.

Here, the seal sticking apparatus provided with the configurations (3-21) and (4-21) to (4-23) may further include the following configurations.
(4-24) Two orthogonal horizontal guide members are provided in each direction with the seal placement surface interposed therebetween.
(4-25) The position adjustment operation control means is configured as means for causing the orthogonal horizontal guide member to perform an approach / separation operation several times or more.

  By adopting such a configuration as well, the permission seal does not move excessively when the orthogonal horizontal guide member is brought into contact with each other, and is aligned at an accurate position from four directions.

Moreover, the seal sticking apparatus provided with the configurations of (3-21) and (4-21) to (4-23) may further include the following configurations.
(4-6) A free bearing structure in which small spheres are rotatably fitted to the tips of the protrusions constituting the seal placement surface.

  Since the entire seal mounting surface has a free bearing structure, the seal moves smoothly during the position adjustment operation using the orthogonal horizontal guide.

  According to the present invention, it is possible to use a license sticker such as a copyright with a high unit price without wasting it.

  Hereinafter, embodiments embodying the present invention will be described. As shown in FIG. 1, the copyright permission seal automatic pasting system 1 as an embodiment is installed and transported at a transport line 10 for transporting a game board and a pasting work position P1 set in the middle of the transport line 10. And a sticker sticking device 100 for sticking a music copyright permission sticker to a place where the permission sticker is attached to the game board. Here, a recognition seal printed with a QR code is affixed to a predetermined location (QR code affixing location) of the game board that is transported along the transport line 10. In the QR code, model code information is recorded. The transfer line 10 is a screw fastening line in the game board assembly line. For this reason, the game board is placed on the pallet carriage and is flowed to the line. Hereinafter, the game board is referred to as work W. Further, the game board and the pallet carriage on which it is placed may be referred to as a work W.

  A QR code reader 200 that reads a QR code from a QR code application position of a work W that has been conveyed on the conveyance line 10 is installed at the QR code reading position P2 upstream of the application work position P1 of the conveyance line 10. Yes. In addition, at the inspection position P3 on the downstream side of the license line sticking work position P1 of the transfer line 10, a license sticker necessary for the work W is stuck at the license sticking position of the work W that has been transported along the transfer line 10. An inspection apparatus 300 for inspecting whether or not it is attached is installed. Further, based on the inspection result by the inspection apparatus, the work (seal where the permission seal is not correctly attached at the place where the permission seal is affixed to the NG information writing position P4 on the downstream side of the installation position of the inspection apparatus 300 on the transport line 10 is provided. An NG information writing device 400 for writing information for specifying as an NG product (including a case where a permission seal is affixed to an unnecessary work) to the pallet truck on which the work W is placed is also provided. is set up.

  Further, the transfer line 10 is provided with screw fastening stations P11, P12,... Where a plurality of screw fastening robots are installed. Each of these screw fastening stations P11, P12,..., QR code reading position P2, pasting work position P1, inspection position P3, and NG information writing position P4 is provided with an auto-stopper, and works for work at each position. It is comprised so that positioning of W may be implemented.

  The control system of this embodiment provided with these devices is configured as shown in FIG. .., 101, 201, 301, 401, sticker attaching device 100, QR code reader 200, inspection device 300, and NG information writing device. 400 is configured such that the operation timing and the like are managed by the line-side control device 50. In the present embodiment, apart from the line side control device 50, the sticker sticking device 100, the QR code reader 200, and the inspection device 300 are also connected to a sticker management personal computer 500. The personal computer 500 is connected to the server 600. Each auto-stopper 31, 32, etc. is provided with a sensor for detecting the completion of the stop / positioning of the workpiece W. When the completion of the stop / positioning is detected, the line-side control device 50 is detected. And a positioning completion signal is transmitted.

  As shown in FIG. 3, the server 600 has a model master 610 in which the correspondence between the model code and the model name is registered, and an attachment necessity file in which the correspondence between the model name and the necessity to attach the permission seal is registered. 620 and a seal type file 630 in which a correspondence relationship between the type of permission seal and the model name is registered are stored as independent files. Each file is independent, but any file can be linked with the model name as a term. That is, when the model code is specified, the model name is specified from the model master 610, and by searching the pasting necessity file 620 using this model name as a term, it is specified whether or not it is a model that needs the sticker sticker. be able to. Next, by searching the seal type file 630 using the model name to which the permission seal is required as a term, the type of the copyright permission seal to be applied to the model is specified.

  In addition to these files, the server 600 also includes a development management file 640 in which a development schedule for each model is registered, an order management file 650 in which order information for each model is registered, and a production in which production management information for each model is registered. A management file 660 and the like are stored so that information can be specified by using the model name as a term. These files 640 to 660 can also be used by linking them via the model master 610.

  As described above, since there is a lot of information to be managed for each model in the gaming machine manufacturer, it is necessary to store various databases in independent files in the server 600 according to the type of information as described above. it makes sense. In particular, the copyright license seal that is the point of this embodiment has the following advantages.

  For example, whether or not it is necessary to attach a copyright license sticker is related to the copyright license sticker with the Music Copyright Association at the beginning of the release of the same model even if there is a long-term demand. Since there was no contract or the like, the sticker was not required until a certain period, but after that, the contract or the like is established and the sticker is required. In such a case, the model master 610 does not need to be rewritten at all, and the corresponding model column in the models registered in the pasting necessity file 620 may be rewritten as pasting required. Further, in the seal type file 630, it is only necessary to add the model name for which a new sticker is required to be added to the corresponding one of the types of copyright permission seals contracted by the gaming machine manufacturer.

  In each file 620 other than the model master 610, the same series may be defined as “the same model”, or the same series may be defined as “different models” depending on the specifications. Good. Also, it is possible to determine such that “same model” and “different models” are distinguished by the difference in the outer frame in the same series.

  The personal computer 500 is installed with an arithmetic processing program for executing processing as shown in FIG. 4 with respect to the present embodiment. When the personal computer 500 receives information read by the QR reader 200 via the line control device 50 by executing this arithmetic processing program (S10: YES), the model master uses the model code obtained by extracting the model code from the information as a term. 610 is searched (S20), and the model name is specified (S30). Next, the sticking necessity file 620 is searched based on the model name (S40), and it is determined whether or not the game board is of a model that needs to be attached with a copyright permission seal (S50). When it is determined that sticker application is required (S50: YES), the seal type file 630 is further searched with this model name to specify the type of seal (S60, S70). And the information which specifies the workpiece | work W determined to be sticker sticking required and the information which specifies the kind of seal | sticker are transmitted with respect to the line control apparatus 50 (S80).

  The line-side control device 50 performs processing for instructing operation timing to each device installed along the transport line 10. Among these, with respect to the QR code reading timing, processing of a procedure as shown in FIG. 5 is performed. First, a stop / positioning command for the workpiece W is transmitted to the automatic stopper 201 at the QR code reading position P2 (S110). When a positioning completion signal is received from the auto stopper 201 (S120: YES), the QR code reader 200 is instructed to start reading the QR code (S130). When a read signal is received from the QR code reader 200 (S140: YES), this signal is transmitted to the personal computer 500 (S150), and an opening command is transmitted to the auto stopper 201 (S160). The above processing is repeatedly executed every time the auto stopper of the screw tightening station located immediately upstream of the QR code reading position P2 opens.

  The line-side control device 50 performs the process of the procedure as shown in FIG. First, a stop / positioning command for the workpiece W is transmitted to the automatic stopper 101 at the sticking operation position P1 (S210). When a positioning completion signal is received from the auto stopper 101 (S220: YES), it is determined whether or not a command regarding whether or not a sticker is required and a seal type is received from the personal computer 500 (S230). If it has been received (S230: YES), it is first determined whether or not a sticker is required (S240). If the sticker is required (S240: YES), the seal type is specified from the received information (S250). Then, the seal application necessity and the determination result of the seal type are transmitted to the seal application device 100 (S260), a flag is entered in the inspection object table, and the inspection object table is notified to the inspection apparatus 300 (S270). And it waits to receive the sticking completion signal from the sticking sticking apparatus 100 (S280). When a pasting completion signal is received (S280: YES), an opening command is transmitted to the auto stopper 101 (S290). If it is determined that the sticker is not required (S240: NO), the process immediately proceeds to S290. The above processing is repeatedly executed every time the auto stopper 201 at the upstream QR code reading position P2 performs the opening operation.

  Here, as shown in FIG. 7, the inspection target table is a table composed of work numbers given as 1, 2,..., Seal types, and inspection flags according to the processing order. In the case shown in the figure, the processing order 101 to 200 is not flagged as out of sticker application. As the seal type, data received from the personal computer 500 is written as it is.

  The line-side control device 50 performs processing of a procedure as shown in FIG. 8 regarding the inspection timing. This process is performed when the work W to which the sticker is attached reaches the inspection position P3 by the process related to the sticking timing of the sticker. The transfer line 10 is originally a screw tightening line, and the work W is repeatedly transferred and stopped by an intermittent operation for the screw tightening operation. For this reason, it can be determined from the number of intermittent operations what number of workpieces has reached the inspection position P3.

  In the inspection timing command process of FIG. 8, a stop / positioning command for the workpiece W is transmitted to the auto-stopper 301 at the inspection position P3 (S310), and whether or not the workpiece that reaches this time based on the inspection target table is an inspection target. Is determined (S320). If it is an inspection target (S320: YES), it waits for reception of a positioning completion signal from the auto stopper 301 (S330). When the positioning completion signal is received (S330: YES), the seal type data of the inspection target table is transmitted to the inspection apparatus 300 together with the inspection start command (S340). Then, it waits to receive a test end signal and a test result from the test apparatus 300 (S350). When an examination end signal is received (S350: YES). It is determined whether or not the inspection result is NG (S360). If it is NG (S360: YES), a flag is entered in the NG writing target table (S370), and then an opening command is transmitted to the auto stopper 301 (S380). If it is not NG (S360: NO), and if it is not an inspection target (S320: NO), the process immediately proceeds to S380. The above processing is executed in synchronization with the intermittent feeding operation of the transport line 10.

  Here, as shown in FIG. 9, the NG writing target table is a table composed of work numbers assigned 1, 2,... According to the processing order, and an NG flag. In the illustrated case, the processing order 99 is NG.

  The line-side control device 50 performs processing of a procedure as shown in FIG. 10 with respect to the NG writing timing. In this process, as with the inspection timing, it is possible to determine what number of workpieces has reached the NG writing position P4 from the relationship with the intermittent feed operation of the transport line 10. The content of the process is that a stop / positioning command for the workpiece W is transmitted to the auto-stopper 401 at the NG writing position P4 (S410), and it is determined whether or not the workpiece that has reached this time is an NG writing target (S420). . If it is an NG writing target (S420: YES), it waits to receive a positioning completion signal from the auto stopper 401 (S430). When the positioning completion signal is received (S430: YES), the NG information writing device 400 is instructed to write NG information (S440). When receiving a writing end signal from the NG information writing device 400 (S450: YES), an opening command is transmitted to the auto stopper 401 (S460). If it is not an NG writing target (S420: NO), the process immediately proceeds to S460. The above processing is also executed in synchronization with the intermittent feeding operation of the transport line 10.

  As shown in FIG. 1B, the QR code reader 200 is a general device that includes a QR camera 202 and reads code data from a photographed image. The inspection apparatus 300 is an image processing apparatus that determines an image captured by a CCD camera by comparing it with an image in a state where a correct permission sticker is pasted at a correct position by pattern matching processing. Furthermore, as shown in FIG. 1C, the NG information writing device 400 is constituted by a display device 402. In the case of NG, the NG information writing device 400 displays NG characters on the display device 402 for a certain period of time. Then, the display on the display device 402 is recorded by the CCD camera 403 installed on the pallet carriage side, so that NG is written in the memory section of the pallet carriage. Since the NG information is written to the pallet truck, the game board that has become an NG product has no problem in shipping as a product if the sticker is re-applied after visual inspection. Therefore, according to the present embodiment, not only NG products can be distinguished, but no NG information is written on the game board itself, so that the value as a product is not impaired.

  Next, the seal sticking device 100 employed in the present embodiment will be described. First, FIG. 11 shows a form of a copyright permission seal to be set in the sticker sticking apparatus 100. As shown in the figure, the copyright permission seal 111 is affixed in a matrix on a rectangular sheet 110 having 10 × 10 = 100 sheets as one unit. Further, a margin is left as a frame-shaped seal 112 at the peripheral edge.

  The sticker sticking apparatus 100 includes a sheet placement holding unit 120 as shown in FIG. 12 in order to prepare the rectangular sheets 110 by stacking them with the seals facing up. In the sheet placement holding unit 120, eight guide pins 121, 121,... Are erected so that at least one or more of the four sides of the rectangular sheet 110 are in contact with each other. More specifically, the guide pins 121, 121,... Are erected near the corners of each side so that the corners of the rectangular sheet 110 can be positioned. By providing a plurality of the sheet placement and holding units 120, it is possible to prepare a plurality of types of permission seals whose colors are changed according to the unit price of one seal, for example.

  Further, the sticker sticking apparatus 100 includes a sheet transfer unit 130 as shown in FIG. 13 in order to suck the rectangular sheets 110 stacked and prepared on the sheet placement holding unit 120 from the top and take them out one by one. . The sheet transfer unit 130 includes two transfer suction pads 131 and 132 that are swingable between a state in which the sheet transfer unit hangs down in a vertical direction and a state in which the sheet transfer unit 130 is inclined. Yes. Then, the upper surfaces of the uppermost ones of the rectangular sheets 110 stacked on the sheet placing and holding unit 120 in a state of hanging vertically are sucked to the two transfer suction pads 131 and 132, and the rectangular sheets are sucked. After raising 110 until it is higher than the tip of the guide pin 121, performing an oscillating motion that oscillates between a suspended state and an inclined state several times and then returning to a vertically suspended state again Control to execute.

  As a result, even when two rectangular sheets 110 are lifted by being overlapped by the suction pads 131 and 132 for transfer, the lower one can be shaken down. At this time, the swaying rectangular sheet 120 is guided by the guide pins 121 and correctly returns to the original position even if the rectangular sheet 120 is tilted when falling and does not fall straight. Even if the suction pads 131 and 132 are temporarily lowered before suction in the next suction operation, the four sides are returned to the correct positions guided by the guide pins 121 even if the guide pins 121 are slightly caught without being correctly returned. Is absorbed.

  Therefore, according to this sticker pasting device 100, the rectangular sheet 110 cannot be simply taken out one by one, but the rectangular sheet 110 is always properly aligned for the seal peeling operation to be performed next. Can be handed over. As a result, it is possible to prevent the two permission seals from being accidentally peeled off in the subsequent seal peeling operation.

  Here, the front and rear suction pads 131 and 132 are configured so that each can perform suction and release independently. This can be realized by opening / closing control of a plurality of valves.

  As a result, as shown in FIG. 14, when the rectangular sheet is transferred to the table unit 141 where the seal peeling operation is performed while the rectangular sheet 110 is adsorbed, the rectangular sheet 110 is moved to the vicinity of the edge 142 of the table unit 141. After the transfer, the transfer suction pad 131 on the front end side of the rectangular sheet is opened, and then the transfer suction pad 132 on the rear end side of the rectangular sheet is moved toward the edge of the table portion and then released. Operation control is performed.

  As shown in FIGS. 15 and 16, the feeding rollers 143 and 144 that feed out the front end of the rectangular sheet 110 by sandwiching the leading end of the rectangular sheet 110 between the table portion 141 and the table portion 141 near the edge 142 of the table portion 141, and the feeding roller 143, 144 pushes and bends the tip of the rectangular sheet 110 protruding from the edge 142 of the table portion 141 downward, and holds the tip of the rectangular sheet 110 pushed and bent downward by the push-bending member 145, The vertical lifting members 146 and 147 to be drawn out and the horizontal support member 148 that can be advanced and retracted toward the edge 142 of the table portion 141 perform a seal floating operation.

  In this operation, first, the feeding rollers 143 and 144 are rotated in the sheet feeding direction (FIG. 16A). Thereby, the front end of the rectangular sheet 110 is slightly protruded from the edge 142 of the table unit 141. When this slightly protruding state is reached, the feeding rollers 143 and 144 are temporarily stopped. In this way, the push-bending member 145 is lowered in a state where the front end of the rectangular sheet slightly protrudes from the edge 142 of the table portion 141 (FIG. 16B). Thus, the protruding end of the rectangular sheet 110 is bent downward. When the pushing and bending are completed, the pushing and bending member 145 is retracted upward (FIG. 16C).

  Next, the horizontal support member 148 approaches toward the front end of the rectangular sheet 110 pushed and bent in this way (FIG. 16D). As a result, the front end of the rectangular sheet 110 is bent at a substantially right angle. If it will be in this state, the vertical drawer members 146 and 147 will be raised, the front-end | tip of the rectangular sheet 110 will be hold | gripped, and it will pull downward (FIG.16 (E)-(G)). At this time, the feeding rollers 143 and 144 are rotated again. The feeding speed by the feeding rollers 143 and 144 and the descending speed of the vertical drawing members 146 and 147 are synchronized so as to be substantially the same. Except for the first drawing, the vertical drawing members 1496 and 147 may be freely rotated according to the sheet drawing operation. In this way, the rectangular sheet 110 is bent downward at a substantially right angle and pulled down, so that the permission seal 111 on the upper surface rises greatly (FIGS. 16G to 16H). At this time, since the horizontal support member 148 has come close to the edge 142 of the table portion 141, the lifted permission seal 111 is received in such a manner as to be surely scooped. As a result, the permission seal 111 advances on the upper surface of the horizontal support member 148 while being lifted from the rectangular sheet 110.

  As shown in FIG. 17, the sticker sticking device 100 has a peeling suction pad 151 having a suction surface large enough to suck only one permission seal 111, and is closer to the feeding rollers 143 and 144 than the peeling suction pad 151. A peeling pressing member 152 provided to be positioned is also provided. Then, among the permission seals 111 in a state of floating on the horizontal support member 148, the seal located at the end in the seal alignment direction on the most distal end side is adsorbed by the peeling suction pad 151 and on the upper surface of the seal adjacent to the flange. The peeling suction pad 151 is raised after the peeling pressing member 152 is brought into contact therewith. As a result, a seal peeling operation is performed, and only one permission seal 111 is peeled off.

Here, as shown in FIG. 17, the peeling pressing member 152 is biased downward by a coil spring, and in the initial state, the lower end is at a position lower than the peeling suction pad 151. Therefore, when the peeling pressing member 152 first comes into contact with the sealing surface, and then the peeling suction pad 151 comes into contact with the sealing surface, the repulsion of the coil spring becomes a resistance to the downward movement, and the contact of the peeling suction pad 151 is reduced. The contact is performed slowly. As a result, the permission seal to be peeled is not strongly pressed against the upper surface of the horizontal support member 148 and firmly attached.
Further, in the sheet transfer control, the sheet is adsorbed only by the rear transfer adsorption pad 132 and positioned for starting the peeling operation. The guide pin 121 is provided so as to position the four corners of the sheet, and the two transfer suction pads 131 and 132 are used to move to the vicinity of the edge 142 of the table unit 141. The sheet leading edge and the edge 142 of the table portion 141 are naturally adjusted so as not to deviate from each other.

  When the permission seal 111 lifted from the rectangular sheet 110 is moved onto the horizontal support member 148 in a state in which at least two sheets (excluding the rear end of the sheet) are arranged in the feeding direction, the above-described peeling adsorption is performed. The peeling operation by the pad 151 and the peeling pressing member 152 is performed.

  Further, the horizontal support member 148 includes a blade 149 whose upper surface is a tapered surface at the tip. As a result, the permission seal 111 lifted from the rectangular sheet 110 can be smoothly received by the horizontal support member 148 by scooping it up with the blade 149.

  This seal peeling operation is executed as an operation of peeling the permission seals 111 on the rectangular sheet 110 one by one sequentially from the peeling start position set using the setting device 160 as shown in FIG. That is, the setting device 160 displays the positions of the 100 permission seals 111 on the sheet 110 as the take-out position setting unit 161 together with the numbers 1 to 100 in a 10 × 10 matrix arrangement. By specifying a number from the setting device 160, it is possible to take out only one in the middle, in an extreme case. However, the setting of taking out one sheet in the middle is not for such a purpose, but for setting the peeling start position when using a sheet partially using the permission seal 111. Note that “1” is set as the default value.

  The peeling operation by the peeling suction pad 151 and the peeling pressing member 152 is sequentially repeated from the top in the sheet width direction. Therefore, in terms of the setting screen of the setting device 160, the first, first, second, third,... In this embodiment, when the first row of seals is peeled off in this manner, the second row is peeled off sequentially from No. 11. Before starting the separation in the second row, the sheet feeding operation for the length of one seal is performed by the feeding rollers 143 and 144 and the vertical drawing members 146 and 147. In addition, it may be set to peel in the reverse direction from No. 20 to No. 19, No. 18, No. 18, and so on.

  As shown in FIG. 19, the seal affixing device 100 transfers the licensed seal 111 that has been peeled one by one to the position just above the temporary placement station 170 while being sucked by the peeling suction pad 151, and lowers and opens it. Thus, temporary placement is executed. At the time of opening, not only the suction is stopped but also air injection is executed. This is because the seal 111 is small and may not be opened only by stopping the suction. The temporary placement station 170 moves linearly between the left and right ends of the temporary placement table 177 shown in the figure. This is to move to the processing position for the subsequent pasting operation.

  As shown in FIG. 20, the temporary placement station 170 includes a seal placement surface 172 formed within the length and width of the permission seal 111 by the tips of a large number of thin protrusions 171, 171,. Four orthogonal horizontal guide members 173 to 176 approaching and separating from two directions orthogonal to the horizontal direction with respect to the surface 172 are provided.

  The four orthogonal horizontal guide members 173 to 176 perform a position adjustment operation that approaches from the center of the seal placement surface 172 to a position separated by half the length of the permission seal 111 or half the width. Therefore, the position of the seal 111 is adjusted by the horizontal guide members 173 and 175 facing in the length direction so that the center in the length direction coincides with the center of the seal placement surface 172. Further, the horizontal guide members 174 and 176 facing the width direction adjust the position of the seal 111 so that the center of the width direction coincides with the center of the seal mounting surface 172.

  As shown in FIG. 21, the permission seal 111 whose position has been adjusted at the temporary placement station 170 is attached to the workpiece W by the attaching suction pad 181 prepared separately from the peeling suction pad 151. Prior to this sticking operation, the position adjustment of the permission seal 111 is performed as described above. Therefore, if the sticking suction pad 181 is stuck on the workpiece W without rotating around the vertical axis, the workpiece W The permission seal 111 can be attached without tilting to W.

  The position adjustment operation by the above-mentioned orthogonal horizontal guide members 173 to 176 is configured to execute the approach / separation operation several times. Thereby, the precision of position adjustment further increases. Further, as described above, since the permission seal 111 is small, it is necessary to execute air ejection when the permission seal 111 is opened. For this reason, there is no denying the possibility that the permission seal 111 may be slightly displaced when temporarily placed on the temporary placement station 170. Therefore, the position adjustment operation by the orthogonal horizontal guide members 173 to 176 is extremely effective in accurately attaching the small permission seal 111 to the workpiece.

  According to the embodiment described above, it is possible for a gaming machine manufacturer to accurately paste a music copyright permission seal 111 having a high unit price on a gaming machine manufacturing / shipping schedule without waste, and Can be used without waste.

  Next, a modified example will be described. The first modification relates to the sheet placement holding unit 120. As shown in FIG. 22, in the first modified example, the length that reaches only the margin portion 112 on the peripheral edge of the rectangular sheet 110 on the upper inner surface side of the eight guide pins 121, 121,. The brush-like projections 122, 122,... Are implanted.

  According to this modification, when the rectangular sheets 110 are stacked and set, the brush-like protrusions 122 are touched to naturally separate the rectangular sheets 110 and also when the rectangular sheets 110 are lifted by the transfer suction pads 131 and 132. The sheet is separated by the end of the sheet 110 coming into contact with the brush-like projection 122. Therefore, the possibility that two or more sheets are lifted by mistake can be reduced. As a result, the movement of the transfer suction pads 131 and 132 during the swinging operation may be very small, and the permission seal 111 can be prevented from being turned over during the swinging operation.

  Next, a second modification will be described. The second modification relates to the transfer suction pads 131 and 132. As shown in FIG. 23, in the second modified example, the front and rear transfer suction pads 131 and 132 are configured to be swingable at independent inclination angles. For this purpose, the support portions 131a and 132a of the suction pads 131 and 132 have a support structure in which the pins 131c and 132c are engaged with the upper and lower slide grooves 131b and 132b. A gear set for swinging the front and rear suction pads 131 and 132 includes a central drive gear 133 and driven gears 134 and 135 meshed side by side in the front-rear direction, and the middle of the support members 131a and 132b. Are connected to the driven gears 134 and 135 at eccentric positions by links 131d and 132d. Thereby, by rotating the drive gear 133 as shown in the drawing, the front and rear suction pads 131 and 132 can be tilted at independent angles, and the rectangular sheet 110 can be swung so as to wave.

  This is because the two rectangular sheets 110 carrying the permission seal 111 on the upper surface so as to be peeled off in a matrix shape are taken out, in addition to the overall adhesion due to static electricity or the like, the adhesive is applied at the portion between the seals. This is because it may be in close contact with each other due to the influence of protrusion. In other words, according to the second modification, since it is possible to make a deformation such that the position close to the edge as well as the center of the sheet is the apex of the curve, it is possible to cope with close contact due to the influence of the protrusion of the adhesive or the like. be able to. Since the apexes of the curve can be formed in various parts in this way, it is not necessary to form a large curve state for the entire sheet. As a result, the effect that the entire sheet is curved so that the sticker 111 that can be peeled off is not shifted or turned up is also exhibited.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this, The various change in the range which does not deviate from the summary is possible.

  For example, the guide pin 121 is a modified example in which the tip is rounded so that the edge is not caught when the sheet is put in and out. It is also an effective modification to have a free bearing structure in which a small sphere is rotatably fitted to the tip of the projection 121 constituting the seal mounting surface 122. Since the entire seal mounting surface has a free bearing structure, the seal moves smoothly during the position adjustment operation using the orthogonal horizontal guide. Further, the writing of the NG information is not electronic but may be mechanical such as driving a pallet detection pin provided in the pallet carriage.

  Also, the rectangular sheet 110 on which a part of the permission seal 111 is used is removed, and the seal that has been lifted between the weights like a pressed flower and returned to a flat state is returned to the top of the sheet placement holding unit 120. Thereafter, when the permission seal is peeled off from the partially used rectangular sheet 110, when the number of the seal at the peeling start position is input using the setting device 160, the feeding rollers 143 and 144 and the vertical pulling member 146 are used. , 147 is also an effective modification in which an idle feed operation corresponding to the peeled seal length is executed.

  For example, as shown in FIG. 24A, if the licensed seals 1 to 25 are used, the seal floating operation is performed after performing the idle feed operation for two seal lengths. . As shown in FIG. 24 (B), when only the permission seals 1 to 9 are used, the seal No. 10 as the seal in the first row is the peeling start position. The action is not executed. Therefore, in the embodiment, as shown in FIG. 25, it is determined what column the setting of the peeling start position by the setting device 160 is from the top (S1010 to S1100), and based on the determination result, there is no idle feed ( S1015) It can be configured to execute the determination that the first row is skipped (S1025),...
