Description

  The present invention relates to a packaging device used when shipping a gaming machine, and more particularly to a packaging device for a gaming machine that wraps and packages a gaming machine with a thin film sheet.

  Pachinko machines, arrange ball machines, slot machines, and other gaming machines require strict management of shipping conditions in view of characteristics such as euphoria, and gaming machine manufacturers have received orders from gaming facilities. The model name, the scheduled amusement facility to be delivered, the number of deliveries, etc. are reported to the gaming machine management institution, a stamp is issued according to the number of deliveries, and the stamp number is printed at the shipping stage when shipping from the factory to the amusement facility Is attached to each game machine and shipped. Accordingly, the gaming machines loaded on the truck from the gaming machine maker are delivered to the gaming facility in a relatively short period of time after shipment, and are installed and fixed on the island facility of the gaming facility. For these reasons, the packaging of gaming machines is mainly intended to prevent dust during transportation. Generally, packaging in the form of packaging in which a thin film sheet is covered and wrapped around the gaming machine is used.

In the amusement machine production factory, labor saving and automation are promoted, and an automatic packing device has been devised for packing at the time of shipment. As such a packing device, for example, a packing device is known in which a thin film-like sheet is formed into a cylindrical shape or an envelope shape, and this is covered with a gaming machine and packed. Specifically, the sealing material wound around the packing roll is fed out, and the lower end portion of the closely attached sheet is pulled back and forth with a suction device to open the sealing bag, and the opened sealing bag is covered from above the gaming machine. It is configured to be lowered so as to be covered, accommodated in a sealed bag, and packaged (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-1104

  However, in the conventional packaging apparatus as described above, it is necessary to use a sealing material in which a sheet used for packaging is formed into a cylindrical shape or an envelope shape, and there is a problem that the material cost is higher than that of a single sheet. It was. Moreover, since such a sealing material is generally formed by blow molding a thermoplastic resin such as polyethylene or polypropylene, there is a problem that the front and back sheets cannot be formed with different properties and materials. .

  In addition, a feeding mechanism that feeds the sealing material wound around the packing roll by a length that matches the height of the gaming machine, and an opening mechanism that opens the sealing bag by sucking the front and rear sheets in close contact are required. The mechanism structure of the packing device becomes complicated and expensive, and it is difficult to ensure stable operation because it directly handles thin film sheets, and it is easy to cause defective packaging due to slight material changes and climate changes. There was a problem.

  Furthermore, even if the upper part of the encapsulated sealing material is welded and cut and the gaming machine is packaged in an envelope-shaped sealing bag, the lower part remains open, and contamination due to dust entrainment from the lower part cannot be prevented. In order to prevent this, if a separate welding mechanism for the lower part is provided, there arises a new problem that the structure of the packaging device is further complicated and expensive.

  The present invention has been made in view of the above circumstances, and provides a packaging device that can use a low-cost sheet or different front and rear sheets according to the purpose, and can perform a stable packaging operation with a simple configuration. The purpose is to do.

  To achieve the above object, the packaging device of the present invention is a packaging device for packaging a gaming machine with a sheet of thermoplastic resin, in which a long first sheet for covering the front side of the gaming machine is wound. The 1st sheet | seat pulled out from each packing roll which supports the 2nd packing roll by which the elongate 2nd sheet | seat for covering the rear surface side of a 1st packing roll and a gaming machine was made to oppose, and was rotated And a roll holding portion that allows the second sheet to be fed out, and the width of the sheet sandwiched from the outside by overlapping the first sheet fed from the first packing roll and the second sheet fed from the second packing roll A welding cutting unit that welds and cuts in the direction, and one side of the gaming machine is brought into contact with the inner surface of the sheet that is welded and joined by the welding cutting unit, and the gaming machine is relative to the longitudinal direction of the joined sheet Move to join Configured moving mechanism which causes wound sheet was (e.g., handling robot 30 in the embodiment) and a. The welding cutting unit includes a plurality of welding structures (for example, a welding heater in the embodiment) provided in parallel in the longitudinal direction of the first sheet and the second sheet, and a plurality of welding structures. It is comprised from the cutting | disconnection structure part (for example, cutting heater in embodiment) which cut | disconnects between the to-be-welded parts of the 1st and 2nd sheet | seat provided and welded between. In this packing apparatus, the first sheet and the second sheet are welded by the welding and cutting unit, and one side surface of the gaming machine is brought into contact with the inner surface of the sheet joined by the moving mechanism, so that the longitudinal direction of the joined sheet The gaming machine is configured to be packaged by relatively moving the gaming machine and welding and cutting the first sheet and the second sheet on the other side of the gaming machine by the welding and cutting unit.

  In the gaming machine configured as described above, a first sheet for covering the front side of the gaming machine and a second sheet for covering the rear side of the gaming machine are used as sheets for packaging the gaming machine. For this reason, a relatively inexpensive single sheet can be used without using a cylindrical or envelope-shaped sealing material, and the material cost of the packaging material can be reduced. Since different sheets can be used for the first sheet and the second sheet, for example, a transparent resin material is used for the first sheet on the front side of the gaming machine, and a translucent or opaque resin is used for the second sheet on the rear side. You can use a material, use a sheet material thicker than the first sheet on the front side for the second sheet on the rear side, or use a different resin material, and play with an appropriate resin material according to the purpose. The machine can be packaged.

  In addition, the first packing roll and the second packing roll are rotatably supported by the roll holding unit, and the first sheet and the second sheet pulled out from each packing roll are arranged to be freely drawn out, and the game machine is operated by the moving mechanism. The first and second sheets joined together are drawn out and wound around the gaming machine by moving the sheet relatively in the longitudinal direction of the sheet, so that the thin film-like first and second sheets are game machines This eliminates the need to provide a feeding mechanism that feeds the length that matches the dimensions of the product and an opening mechanism that sucks the sheet in close contact to open the sealed bag, simplifying the mechanism configuration of the packaging device and reducing costs. At the same time, stable operation can be ensured regardless of changes in sheet material or climate.

  Further, the welding and cutting unit is provided with a plurality of welding structure portions extending in the width direction of the first and second sheets arranged in the longitudinal direction of the sheet, and the welded portions of the first and second sheets therebetween. The cutting structure part which cut | disconnects between is provided, and a 1st sheet | seat and a 2nd sheet | seat are welded up and down a cutting line by pinching | interposing a 1st sheet | seat and a 2nd sheet | seat by a welding cutting unit. For this reason, for example, the lower surface of the gaming machine is brought into contact with the inner surface of the welded sheet, and the gaming machine is moved downward, and the first and second sheets are welded and cut on the upper surface side of the gaming machine by the welding cutting unit. Thus, the gaming machine is heat-sealed at both the upper part and the lower part, and a lower-side seal for packaging the next gaming machine is formed on the packing roll side. Therefore, it is possible to provide a packaging device that can seal both the upper and lower sides in a single welding cutting process for each gaming machine without complicating and increasing the configuration of the packaging device.

  Therefore, according to the present invention, it is possible to use a low-cost sheet or different front and rear sheets depending on the purpose, and it is possible to provide a packaging apparatus capable of stable packaging operation with a simple configuration.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. FIG. 1 schematically shows a process until a game machine such as a pachinko machine temporarily stored in the product warehouse 10 is loaded onto a truck TR through a shipping line, and FIG. 2 shows an overall layout as a layout diagram. First, the overall flow of the shipping process will be outlined with reference to these drawings.

  The pachinko machine PM assembled through the processing and assembling process is positioned on a pallet 12 where about 15 pachinko machines can be positioned and loaded, and the model and number of pachinko machines PM loaded on the pallet 12 Is specified, and is carried in from the warehousing port side (not shown) and stored in the product warehouse 10. A large number of storage shelves 11 whose shelf addresses are specified are provided in the product warehouse 10, and each storage shelf 11 stores a pallet 12 on which a pachinko machine PM is mounted. Loading and unloading of the pallet 12 to and from the storage shelf 11 is managed based on the shelf position information, and loading and unloading are performed by an automatic loading and unloading device (not shown).

  Conveying rails 14 are provided adjacent to the product warehouse 10 on the exit side, and six rows of shipping lines 20 are provided across the conveying rails 14. The transport rail 14 is formed in a loop between the product warehouse 10 and the shipping line 20, and six delivery stations 15 are provided corresponding to the six rows of shipping lines 20. Six rows of shipping lines are provided adjacent to each other in two rows, and three transfer robots 18 are arranged between two adjacent left and right delivery stations 15 and 15 in total.

  When a command signal (game machine transport request) is issued from the shipping line 20 based on the shipping schedule, the automatic loading / unloading device is loaded with a corresponding type of pachinko machine from the storage shelf 11 of the product warehouse based on the shelf position information. The pallet 12 is pulled out and carried onto the transport rail 14, and the pallet 12 carried onto the transport rail 14 is transported to the left or right unloading station 15 on the shipping line 20 according to the shipping command. When the pallet 12 is stopped at the unloading station 15, the pachinko machine PM on the pallet 12 is picked up one by one by the transfer robot 18 and transferred to the standby stage 21 provided at the front stage of the shipping line 20.

  Each shipping line 20 is composed of a standby stage 21, a stamp sticking stage 22, a packing stage 23, a shipping label sticking stage 24, and the like, and a pachinko machine PM transported to the standby stage 21 by the transport robot 18 is provided in this line. The transport mechanism 25 sequentially sends the stamp from the standby stage 21 to the stamp pasting stage 22, and the stamp is pasted on the packing stage 23. The shipping label is pasted on the shipping label pasting stage 24. A shipping assist device 60 is arranged at the end of the shipping line 20, and the pachinko machine PM with the shipping label attached is loaded into the truck TR stopped in the shipping bay EXB using the shipping assist device and shipped to the delivery destination. The As described above, six rows of shipping lines are provided, and it is configured so that shipping operations can be performed in parallel on the six rows of shipping lines according to the shipping schedule.

  In the shipping system generally configured as described above, first, a shipping transport system in which the transport robot 18 picks up the pachinko machine PM and transports it to the shipping line 20 from the pallet 12 transported to the unloading station 15 is shown in FIGS. This will be described in detail below with reference to FIG. Here, FIG. 3 is a layout diagram showing a partially enlarged view of two adjacent rows of shipping lines 20, FIG. 4 is an explanatory diagram schematically showing the transport status of the pachinko machine PM in this shipping transport system, and FIG. FIG. 6 is a timing chart illustrating an operation state of the shipping and conveying system. FIG. 6 is a flowchart showing an outline of distribution control in the shipping and conveying system.

  As explained in the outline, six rows of shipping lines 20 are provided adjacent to each other in two rows, and three transfer robots 18 are arranged between two adjacent left and right delivery stations 15 and 15 in total. Has been. That is, the three transfer robots 18 each have two rows of shipping lines 20 and 20, and transfer the pachinko machine PM to these two rows of shipment lines.

  Here, since the shipping station 15 is provided corresponding to the shipping line 20, the shipping line 20 (from the pallet 12 conveyed to the shipping station 15 (for convenience, A station 15A and B station 15B) ( Similarly, as a means for transporting the pachinko machine to the A line 20A and the B line 20B), the delivery station 15 and the shipping line 20 are directly associated with each other so that the A station 15A → the A line 20A and the B station 15B → It is also possible to set the conveyance pattern to 1: 1 correspondence like the B line 20B.

  However, the pachinko machine PM to be shipped is stored in the storage shelf 11 of the product warehouse in a state of being loaded on the pallet 12, and a predetermined transfer time is required while being transferred to the shipping station 15 after the shipping command is issued. is required. In addition, the pallet transport to the delivery station 15 is set to start after the empty pallet is stored at the original shelf position in order to prevent duplicate delivery, and the recovery of the empty pallet also requires a predetermined recovery time. . Accordingly, when the same model of the pachinko machine PM is shipped from both the A and B lines, considering the pallet 12 transport time, recovery time, etc., for example, the pallet is being transported to the B station 15B (or being recovered) ), The pachinko machine on the pallet located at the A station 15A is divided into the A line 20A and the B line 20B and conveyed, and the shipping process is performed in parallel on both the A and B lines.

  Therefore, in the present shipment conveyance system, when the same model of the pachinko machine PM is shipped from both the A line 20A and the B line 20B, when the pallet 12 is conveyed to the shipping station 15A or 15B, the pallet The upper pachinko machine is divided into an A line 20A and a B line 20B, and is conveyed alternately, and is configured to ship in parallel on both the A and B lines.

  On the other hand, the stamp line pasting stage 22 in the shipping line is a first stamp sheet pasting step for pasting the stamp base sheet and the first certificate sheet on the front side of the game board, and a second label sheet for pasting the second certificate sheet at a predetermined position on the back side of the front frame. The pachinko machine PM received in this stage 22 is sequentially sent to the next process, which includes a verification stamping process and a verification process for verifying the stamp numbers of the first and second stamps. The pachinko machines that have been verified in the verification process are sent to the next packing stage 23 one by one. In the certificate pasting stage 22, since the first and second certificate stamps issued by the gaming machine management organization and printed with individual certificate numbers are handled, strict management is required, and the work of each process is performed by the operator. Is called. For this reason, the processing efficiency of the two lines A and B is not the same, and there is a relative difference in the processing efficiency (processing speed). As a result, a situation in which the shipping operation of the shipping line is stagnant may occur.

  In such a case, in the shipping and conveying system configured to alternately convey the pachinko machine PM to the A line 20A and the B line 20B regardless of the progress of the operations of both the A and B lines, the relative processing is performed. A low-efficiency shipping line, for example, a B line 20B delays the operation of the pachinko machine to the B line (becomes a standby state), while the A line 20A has a relatively high processing efficiency. Since the pachinko machine to be transported does not reach along with the stagnation of the transport of the pachinko machine to 20B, a wasteful waiting time occurs. In addition, if a trouble occurs in which the shipping operation must be interrupted on either the A or B shipping line, for example, the A line 20A, the operation of the A / B line shipping / conveying system is once stopped and the A line 20A is transported. If the process of removing from the front is not performed, the state until the transfer process to the B line 20B remains in a standby state, and the transfer system is substantially stopped.

  Therefore, in the shipping and conveying system in the main factory, the pachinko machine PM conveyed by the conveying robot 18 is received at the front stage of each shipping line 20 until the pachinko machines are sequentially processed according to the progress of work on the shipping line 20. A standby stage 21 for temporarily waiting is provided, and the system is configured such that the transfer robot 18 gives priority to transfer to a shipping line in which the standby stage is vacant in accordance with the presence of the standby stage 21. .

  That is, in the configuration in which pachinko machines are distributed and transported to the A line 20A and the B line 20B, even if it is originally the order of transporting to the A line, the shipping process of the A line 20A may be performed. If there is no room to accept the pachinko machine PM in the standby stage 21A of the A line due to a delay or the like, and there is a free room in the standby stage 21B of the B line 20B, the transfer robot gives priority to the transfer to the B line 20B. Then, after the transfer process to the B line 20B is completed, the transfer process is performed again according to the empty state of the standby stage 21A for the A line and the empty state of the standby stage 21B for the B line.

  Specifically, the standby stage 21 (21A, 21B) includes a plurality of pachinko machines, for example, a loading table that can hold three pachinko machines PM in parallel as shown in the drawings, and a stamp sticking line. When a pachinko machine waiting and held at the entrance of 22 is taken into the certificate sticking stage 22, a progressive mechanism for sequentially moving the pachinko machine on the loading platform to the entrance side of the certificate pasting line 22, and a pachinko on the loading platform A stock detector (for example, a detector such as a photoelectric sensor or a limit switch) for detecting the stock status of the machine is provided. The detection signal of the presence detector is input to the control device of the shipping conveyance system.

  Then, the pachinko machine that has completed the collation process in the stamp pasting stage 22 is sent out to the packing stage 23, and the pachinko machines in the stamp pasting stage 22 are sequentially sent to the next process in the stage to the entrance position of the stamp pasting line 22 When the pachinko machine held on standby is taken into the sticker mount and the first sticker sticking step, the pachinko machine remaining on the loading base is sequentially moved to the entrance side of the sticker sticking line 22 by the progressive mechanism. An empty space on which the pachinko machine PM can be placed is formed on the opposite loading platform. The stock status of the pachinko machine on the loading platform is detected by the stock detector and is input to the transport control device of the shipping transport system. The transport control device receives both the A and B lines input from the stock detector. The transfer to the shipping line in which the standby stage 21 is vacant is prioritized according to the stock status.

  As shown in the flow chart of this transport control in FIG. 5, when a transport request for a gaming machine is input from the shipping line 20 in step S1, the shipping master of the shipping line 20 that has been transported in step S5 is referred to the shipping master. In step S10, it is determined whether the shipping lines 20A and 20B are parallel shipments of the same model. Then, in the case of parallel shipment of the same model, the process proceeds to step S20 to execute the distribution transfer shipping transfer process (shipment transfer process of the present transfer system), and in other cases (for example, different model parallel shipment or single line shipment). To proceed to step S12, another shipping / conveying process (for example, the above-described 1: 1-compatible shipping / conveying process) is executed.

  In step S20, it is determined whether or not there is a space in which the pachinko machine can be placed on the standby stage 21A of the A line based on the input signal from the stock detector of the standby stage 21A, and it is determined that there is a space. In step S21, the A-line empty flag F1 is turned on and the process proceeds to step S30. When it is determined that there is no empty, the A-line empty flag F1 is turned off in step S22 and the process proceeds to step S30. In step S30, whether or not there is a vacant space in which the pachinko machine can be placed on the standby stage 21B of the B line is determined based on an input signal from the stock detector of the standby stage 21B. In step S31, the B line empty flag F2 is turned on and the process proceeds to step S40. When it is determined that there is no empty, the B line empty flag F2 is turned off in step S32 and the process proceeds to step S40.

  In step S40, it is determined whether or not both the A line empty flag F1 set in steps S21 and S22 and the B line empty flag F2 set in steps S31 and S32 are on. If it is determined in step S40 that both the flags F1 and F2 are on, the process proceeds to step S41. Otherwise, the process proceeds to step S45.

  If it is determined in step S40 that both the flags F1 and F2 are on, that is, if both the standby stage 21A for the A line and the standby stage 21B for the B line are free, the basic two lines in step S41. Alternating supply processing is performed. Specifically, the operation of the transfer robot 18 is controlled so that the pachinko machines are alternately transferred to the A and B lines, and the pachinko machine is transferred from the pallet 12 to the standby stage (for example, 21A) of the shipping line in the order to be transferred. Is done. In step S60, it is determined whether or not the pallet 12 is empty. If it is determined that the pallet 12 is not empty, the process returns to step S15 and the processes in and after step S20 are repeated, and it is determined that the pallet 12 is empty. In this case, the conveyance process for the pallet 12 is finished.

  On the other hand, in cases other than the case where it is determined in step S40 that both flags F1 and F2 are on, it is determined in step S45 whether or not both flags F1 and F2 are off, and it is determined that both are off. If so, go to Step S47, otherwise go to Step S50.

  The case where it is determined in step S45 that both the flags F1 and F2 are OFF is when both the standby stage 21A for the A line and the standby stage 21B for the B line are not empty (full state). In step S47, a supply standby process is performed. For example, after a certain standby time set by the timer means has elapsed, the process returns to step S15 and the processes in and after step S20 are repeated.

  In step S50, it is determined whether or not the A line empty flag F1 is ON. The determination process in step S50 is performed when the flags F1 and F2 are both on (both both standby stages are empty) or both are off (both standby stages are full). Is a case where there is a vacancy only in one of the standby stages A and B. When the flag F1 is on, only the standby stage 21A of the A line has a vacancy, and when the flag F1 is not on, it means that only the standby stage 21B of the B line has a vacancy.

  Therefore, if it is determined in step S50 that the A line empty flag F1 is on, the process proceeds to step S51, where priority supply processing to the A line 20A is performed, and if the A line empty flag F1 is not on in step S50. When it is determined, the process proceeds to step S52, and the priority supply process to the B line 20B is performed.

  For example, in the A-line priority supply process in step S51, the conveyance robot 18 is configured to supply the pachinko machine PM preferentially to the A-line 20A regardless of which line is supplied in an alternate supply. The operation is controlled, and the pachinko machine PM is conveyed from the pallet 12 to the standby stage 21A of the A line. The same applies to the B line preferential supply processing in step S52. In step S60, it is determined whether or not the pallet 12 is empty. If it is determined that the pallet 12 is not empty, the process returns to step S15 and the processes in and after step S20 are repeated, and it is determined that the pallet 12 is empty. In this case, the conveyance process for the pallet 12 is finished.

  As a means for determining whether or not the pallet 12 is empty, for example, using the shelf position information, the number of pachinko machines already transferred to the standby stage from the number of pachinko machines PM loaded on the pallet 12 is calculated. Means for determining whether the remaining quantity is zero by performing subtraction processing, means for determining whether the pachinko machine PM is loaded on the pallet by providing a detection means for the pachinko machine PM on the pallet 12 or the station 15, etc. Any means may be used.

  FIG. 6 exemplifies a timing chart of the transport control based on this control flow. In order from the top of FIG. 6, (a) the state of the flag F1 indicating the vacant state of the standby stage 21A of the A line, (b) B The state of the flag F2 indicating the empty state of the standby stage 21B of the line, (c) the supply operation of the transfer robot 18 to the A line 20A, and (d) the supply operation of the transfer robot 18 to the B line 20B are shown. Yes.

A time region I in FIG. 6 shows a situation in which both the shipment work in the A line 20A and the shipment work in the B line 20B are proceeding smoothly. In the shipment conveyance system, the conveyance process determination (step S40). ) At time t ₁ , t ₂ , t ₃ , which is the time of determination), the flag F1 indicating the availability of the A line (standby stage 21A) and the flag F2 indicating the availability of the B line (standby stage 21B) Since the two-line alternate supply process (step S41) is executed, the transport robot 18 is controlled to alternately supply the pachinko machine PM to the A line 20A and the B line 20B. The machine PM is alternately conveyed to the standby stages 21A and 21B.

Time domain II shows the situation when a delay occurs in shipping operation in the B line 20B, at time t ₄ transportation process determination flag F1 is turned on indicating the availability of the A-line, the availability of line B The flag F2 indicating is OFF. For this reason, the A-line priority process (step S51) is executed in the shipping conveyance system, the conveyance robot 18 is controlled to supply the pachinko machine PM preferentially to the A line 20A, and the pachinko machine PM on the pallet 12 is controlled to the A line. To the standby stage 21A. In this stage, even if the sheets are alternately conveyed, the order is to supply to the A line 20A.

However even at the time t _5, a flag F1 indicating the availability of the A-line is on, the flag F2 indicating the availability of the B line is off. For this reason, the pachinko machine is supplied to the B line in the case of alternating conveyance, but the A line priority process (step S51) is executed again in the shipping conveyance system, and the conveyance robot 18 transfers the pachinko machine PM to the A line 20A. The pachinko machine PM on the pallet 12 is transported to the standby stage 21A of the A line.

The time region III shows a situation when a trouble occurs in the A line 20A, and the flag F1 indicating the vacant state of the A line is turned off at times t ₆ , t ₇ , t ₈ . The flag F2 indicating the availability of the B line is ON. For this reason, the B-line priority process (step S52) is executed in the shipping conveyance system, the conveyance robot 18 is controlled to supply the pachinko machine PM preferentially to the B line 20B, and the pachinko machine PM on the pallet 12 is transferred to the B line. Are repeatedly and intermittently conveyed to the standby stage 21B.

  As described above, according to the above-described shipping conveyance system, even if any of the plurality of shipping lines has a lower processing efficiency than the other shipping lines, or a trouble occurs in any of these lines, these Accordingly, it is possible to respond to the situation quickly and flexibly, and to perform an appropriate conveyance process, thereby improving the shipping process efficiency of the entire shipping system.

  Now, the pachinko machine PM thus transported from the pallet 12 to the standby stage 21 is sequentially taken into the stamp sticking stage 22 according to the progress of the shipping line 20, and in the first stamp sticking process in this stage, The certificate backing paper and the first certificate paper are affixed at the predetermined positions, the second certificate paper is affixed to the predetermined position on the back side of the front frame in the second certificate paper affixing process, and the first certificate paper and the second certificate paper are verified in the verification process. The stamp number and the delivery destination are verified. The pachinko machine PM that has been verified in the verification process is sent to the packing stage 23 by the transport mechanism 25.

  The packing stage 23 is provided with an automatic packing device 23M, and the pachinko machine PM to which the certificate paper is pasted is automatically packed at the packing stage 23. 7 to 9 show the automatic packing device, and FIGS. 10 and 11 show the packing process by the automatic packing device.

It is configured so that it can be adjusted and fixed.

  Below the side welding unit 46, a delivery mechanism 48 is provided between the front mechanism 40a and the rear mechanism 40b. The delivery mechanism 48 mainly includes a roller conveyor 48a having a plurality of rotating rollers in which a motor is incorporated inside the roller. The upper surface of the roller conveyor 48a has a slightly wider interval than the width in the front-rear direction of the pachinko machine PM. The pachinko machine is guided by the attached guide plate and guided to the adjacent shipping label attaching stage 24.

  The operation of the packaging device main body 40 is controlled by the packaging control device of the shipping and conveying system, and controls the supply of air to the upper first and second cylinders 45s and the side cylinder 46s, so that the heater holder 45h of the welding and cutting unit 45 is obtained. The extension operation and the drawing operation of the heater holder 46h of the side welding unit 46 (first holder unit and second holder unit) are controlled. Therefore, the operation of the automatic packing device 23M configured as described above will be described below.

  First, the pachinko machine PM sent out from the stamp pasting stage 22 by the transport mechanism 25 and carried into the packing stage 23 is introduced into the stage by the roller conveyor 26a of the introduction mechanism 26 and stopped at the reference position. Input from the introduction detector 26c to the packing control device.

  When the signal is input, the packing control device lowers the Z-axis carriage 33 of the handling robot 30 to dispose the clamp arm 35a on the left and right sides of the pachinko machine, and supplies air to the clamp cylinder 35s to Each of the clamp arms 35a is pivoted inward to sandwich the outer frame from the left and right sides, and a plurality of locking pins provided on the clamp arm are bitten into the outer frame to hold the pachinko machine PM so that it can be lifted. Next, the Z-axis stepping motor is rotationally driven to raise the Z-axis carriage 33, and the X-axis stepping motor is rotationally driven to move the X-axis carriage 32 to the right so that the pachinko machine PM held by the clamp 35 is moved. It arrange | positions above the packaging apparatus main body 40 (refer FIG. 9). Then, the Z-axis stepping motor is rotationally driven to lower the Z-axis carriage 33 at a low speed, and the pachinko machine PM is slowly lowered between the front and rear mechanism portions 40a and 40b (see FIG. 10C).

  Then, first, the bottom surface of the pachinko machine PM comes into contact with the inner surfaces of the first and second sheets welded and joined in advance, and the first packing roll 41r and the second packing roll 42r to which appropriate friction is applied, respectively, The Z-axis carriage 33 is stopped descending at a height position where the lower surface of the pachinko machine is supported by the feeding mechanism 48 while feeding the sheet having a length corresponding to the lowered position. Then, the left and right clamps 35 are released, the Z-axis carriage 33 is raised, the X-axis carriage 32 is moved to the left, and the handling robot 30 returns to the original standby position. Thus, the pachinko machine PM is positioned between the first sheet 41 and the second sheet 42 stretched in a V shape in a side view (see FIG. 11A) and supported on the delivery mechanism 48. The At this time, the rotating roller of the delivery mechanism 48 is stopped.

  Then, after the left and right clamps 35 are retracted upward, the packaging operation by the welding and cutting unit 45 and the side welding unit 46 is started. In the packaging operation, first, air is supplied to the bottom side port of the upper first cylinder 45s in the welding / cutting unit 45, and the first holder assembly of the heater holder 45 protrudes upward from the front and rear mechanism frames 47 toward the center and above the pachinko machine. It is. The first holder assembly is an assembly in which the first, third, and fifth stage holder plates in the five-stage heater holder 45 are connected, and the first stage and the fifth stage by the extension operation of the first holder assembly. The first sheet 41 and the second sheet 42 are elastically sandwiched and fixed by the sheet presser 45ho provided on the step, and the third-stage cutting heater 45hc sandwiches the first and second sheets in between. Touched in state.

  Next, air is supplied to the bottom second port of the upper second cylinder 45 s of the welding cutting unit 45 and the side cylinder 46 s of the side welding unit 46, and the second holder assembly of the heater holder 45 and the left and right heater holders 46 h are moved from the mechanism frame 47. Projected toward the center. The second holder assembly is an assembly in which the second and fourth stage holder plates in the five-stage heater holder 45 are connected. The second holder assembly is provided in the second stage and the fourth stage by the extension operation of the second holder assembly. The welding heater 45hw is held in contact with the first and second sheets sandwiched above and below the cutting heater 45hc. Further, the first sheet 41 and the second sheet 42 are elastically sandwiched and fixed by the first-stage and third-stage sheet pressers 46ho on the side of the pachinko machine PM by the overhanging operation of the left and right heater holders 46h. At the same time, the second stage welding heater 46hw is held in contact with the first and second sheets in between.

  Then, after a lapse of a predetermined time since the first holder assembly in the welding and fusing unit 45 has passed (after a lapse of a predetermined time from the start of contact with the cutting heater 45hc), air is supplied to the head side port of the upper first cylinder 45s, The first holder assembly is pulled into the mechanism frame 47. In addition, after the elapse of a predetermined time from the extension of the second holder assembly in the welding fusing unit 45 and the extension of the heater holder 46h of the side welding unit 46 (after the elapse of a predetermined time from the start of contact of the welding heaters 45hw and 46hw), the upper second Air is supplied to the head side ports of the two cylinders 45s and the side cylinders 46s, and the second holder assembly and the left and right heater holders 46h are drawn into the mechanism frame 47.

That is, in the automatic packing device 23M, the heating temperature of the welding heater and the cutting heater is set to substantially the same temperature, and welding and cutting are performed by controlling the contact time of each heater. For this reason, the overhang time of the first holder assembly is set to a time suitable for fusing the first and second sheets 41 and 42 by the cutting heater (cutting time T ₁ , for example, about 3 to 5 seconds). The extension time of the two-holder assembly and the heater holder 46h is set to a time suitable for welding the first and second sheets 41 and 42 by the welding heater (welding time T ₂ , for example, about 2 to 4 seconds).

In the automatic packing apparatus M shown in the present embodiment, first, the first holder assembly in the welding fusing unit 45 is first projected to contact the cutting heater, and then the time difference Δt = T ₁ −T between the cutting time and the welding time. ₂ , the second holder assembly and the heater holder 46h are extended to contact the welding heater, and after the time T ₁ and T ₂ have elapsed, all the heaters are drawn simultaneously.

  When the first holder assembly and the second holder assembly of the welding fusing unit 45 are drawn into the mechanism frame 47, and the heater holder 46h of the left and right side welding units 46 is drawn into the mechanism frame 47, the pachinko machine PM The first sheet 41 on the side and the second sheet 42 on the rear side are welded so that all the upper and lower sides and the left and right sides are welded, and separated from the first and second sheets welded and joined on the upper side, the pachinko machine PM Packaging is complete.

  When the packaging of the pachinko machine PM is completed, the rotary roller of the delivery mechanism 48 is driven to rotate and is guided by the guide plate provided on the upper surface of the roller conveyor 48a, so that the pachinko machine PM is delivered to the shipping label pasting stage 24.

  Thus, according to the automatic packing apparatus 23M as described above, since the single sheet can be used as the first sheet 41 and the second sheet 42, the material cost of the packing material can be reduced, and each sheet can be reduced. Since the same material or different materials can be used, it is possible to package the pachinko machine by selecting an appropriate resin material according to the purpose.

  In addition, by moving the pachinko machine relatively in the longitudinal direction of the sheet, the first and second sheets are drawn out and wound around the pachinko machine. There is no need to provide a feeding mechanism that feeds the matching length or an opening mechanism that opens the sealed bag by sucking a sheet that is in close contact, ensuring a stable operation while reducing costs with a simple configuration. Can do.

  Further, since the welding heater 45hw is provided above and below the cutting heater 45hc in the welding / cutting unit 45, the upper surface of the pachinko machine to be packaged is operated by sandwiching the first and second sheets above the pachinko machine. Side welding, separation from the first and second sheets above it, and welding on the lower surface side of the pachinko machine that is the next packaging target can be performed simultaneously, making the configuration of the packaging device complicated and expensive Therefore, it is possible to provide a highly productive packaging device.

  In addition, although the structure example which controls the contact time of each heater by making the heating temperature of the welding heater and the cutting heater the same for the welding and cutting of the packing sheet is shown, the temperature of the cutting heater is set higher than the temperature of the welding heater And it can also be set as the structure which makes the contact time of all the heaters the same. According to such a structure, the structure of the welding cutting unit 45 can be simplified. Moreover, although the structural example cut | disconnected thermally using the cutting heater 45hc was shown as a cutting | disconnection structure part which cut | disconnects a packing sheet, For example, it seems to cut mechanically using a rotary type cutter or a shearing type cutter. It may be a simple configuration. Furthermore, although the configuration in which the pachinko machine PM is moved up and down in a standing posture by the handling robot 30 is exemplified, the posture and moving direction of the gaming machine may be other postures or directions, and the gaming machine is fixed The form which moves the packaging apparatus main body 40 relatively may be sufficient.

  On the shipping label pasting stage 24 adjacent to the packing stage 23, an automatic label for pasting a shipping label clearly indicating the delivery destination of the pachinko machine on the upper surface of the sheet of the pachinko machine PM sent out after being packed by the automatic packing device 23M.

The chain 66c hangs down along the part 63a, and the sprocket drive motor 67 is connected to the rotating shaft of the lifting structure 66 through a speed reduction mechanism.

  The roller conveyor 61 is disposed on the upper part of the base frame 62 through the inside of the gate-shaped subframe 63, and is pivotally connected to each other at the rear end portion by a connection support structure 64 provided on the base frame 62. It is supported so that it can swing. Further, on the front end side of the base frame 62, chains 66c and 66c hanging along the left and right leg portions 63a and 63a are connected to the left and right side portions of the roller frame 61f through turnbuckles. As a result, the roller conveyor 61 is supported so as to be able to swing up and down around the several axes of the connection support structure 64, and is stably supported at the angular position lifted by the left and right chains 66 c of the lift mechanism 65.

  Then, by rotating and driving the sprocket drive motor 67 of the lift mechanism 65 to wind or feed the chain 66c, the front end side of the roller conveyor 61 can be swung up and down around several connecting shafts of the connection support structure 64. By adjusting the rotational angle position of the sprocket 66s, the height position of the front end portion of the roller conveyor 61 can be adjusted to an arbitrary height. Further, in the shipping auxiliary device 60, a connection support structure 64 for connecting the roller conveyor 61 and the base frame 62 is set at the rear end of each other, and is arranged close to the rotation shaft of the roller at the rear end position in the roller conveyor 61. ing. For this reason, even if the roller conveyor 61 is swung up and down by the lift mechanism 65, the arrangement position of the rollers at the rear end position hardly changes.

  Therefore, an operator who loads the pachinko machine PM adjusts the position of the front end side of the shipment assisting device 60 in accordance with the stop position of the truck TR stopped in the shipping bay EXB, and loads the truck TR. By adjusting the height position of the front end portion of the roller conveyor 61 by the lift mechanism 65 according to the height position, the front and rear ends of the shipment assisting device 60 can be installed without any step, thereby shipping The end of the line and the loading platform of the truck TR can be connected by the roller conveyor 61 without a step. The roller conveyor 61 uses a rotating roller with a built-in motor. Even if the roller conveyor 61 is inclined forward and inclined, a pachinko machine or the like placed on the rear end roller is used as the roller conveyor 61. It is conveyed to the front end side.

  For this reason, the worker who performs the loading work places the pachinko machine PM sent to the carry-out roller way 55 on the rear end of the roller conveyor 61 according to the work situation on the loading platform side of the truck, or the motor By turning on / off the power supply to the rollers, the pachinko machine PM can be easily transported to the truck bed.

  As described above, according to the shipment assisting device 60, even if the vehicle type and type of the truck to be dispatched are different and the carrier height is various, the roller conveyor 61 according to the height position of the cargo carrier of the truck. By raising and lowering the front end side, the step between the front end portion of the roller conveyor and the loading platform can be eliminated, and the burden of loading work can be reduced. Further, a sub-frame 63 is formed so as to straddle the roller conveyor 61, the lift mechanism 65 is disposed on the top plate 63b, and the roller conveyor 61 is lifted and supported by a chain 66c suspended along the leg portion 63a. Therefore, the drive mechanism for raising and lowering the front end side of the roller conveyor 61 does not protrude to the left and right sides, and the installation area in the width direction of the shipping assist device can be greatly suppressed.

  Further, since the connection support structure 64 that pivotally connects the roller frame 61 and the base frame 62 is disposed close to the rotation shaft of the roller at the rear end of the conveyor, the roller conveyor 61 is swung up and down by the lift mechanism 65. However, the arrangement position of the roller at the rear end position hardly changes. For this reason, it is not necessary to provide an adjustment mechanism on the rear end side to correct the height shift caused by the elevation of the roller conveyor front end side, and it has a simple configuration and does not cause a step at the front and rear end portions of the roller conveyor. An auxiliary device can be configured.

  In this embodiment, as a configuration example of the lift mechanism 65 that swings the roller conveyor 61, a configuration example in which the roller conveyor 61 is lifted by the chain 66c is shown, but the lift mechanism is limited to such a configuration example. Instead, for example, a cam that pushes up the roller conveyor 61 is rotatably disposed on the base frame 62, a sprocket connected to the cam is disposed, and a chain is hung between the sprocket disposed on the top plate. The roller conveyor 61 may be pushed up by swinging the cam by swinging it with a sprocket drive motor, and the front end of the roller conveyor may be moved up and down.

  In addition, although a pachinko machine has been illustrated as a representative example of a gaming machine, the present invention is similarly applied to other ball game machines such as an arrangement ball machine and a sparrow ball game machine, or a gaming machine such as a slot machine, and the same effect is obtained. Obtainable.
