It comprises a left wall portion 45 and a right wall portion 46 to be protected. On the upper surface of the lower wall portion 44, a recess 44a capable of accommodating the support member 36 is formed at a position corresponding to each support member 36 that supports the lower surface of the game board 13 so as to extend in the front-rear direction. . The cushioning material 43 according to the embodiment has a double structure in which corrugated cardboard sheets are folded, and a recess 44a is formed by notching a sheet stacked on the upper side. In the embodiment, the recess 44a extends to the rear end of the cushioning material 43 (the end on the side where the support member 36 moves from the support position to the release position), but the recess 44a should not reach the rear end. Thus, the strength may be prevented from decreasing by maintaining the state where the left and right sheets are connected at the rear end.

  Further, the lower wall portion 44 is formed with a pair of notches spaced apart in the left-right direction in the middle in the left-right direction with a predetermined length from the rear end side to the front side, so that the front side is between the notches. A support piece 44b that can be bent so as to stand up as a fulcrum is provided. The support piece 44b is provided at a position capable of supporting the lower surface of a component 28 such as a control device attached to the back surface of the game board 13 (see FIG. 11). The left and right wall portions 45 and 46 are respectively formed with handle holes 47 at upper positions that do not come into contact with the side surfaces of the game board 13 when the cushioning material 43 is attached to the game board 13. In addition, a concave groove 48 extending in the vertical direction is formed on the inner surface side of the left and right wall portions 45, 46 facing the side surface of the game board 13, and a plate member in the game board 13 is formed in the concave groove 48. The movement of the game board 13 in the front-rear direction can be restricted by fitting the end portions of 27.

[Operation of the first embodiment]
Next, the operation of the game board packing line according to the first embodiment will be described.

  As shown in FIG. 1, the control means 23 causes the box making machine 10 to assemble the packaging box 11 under the condition that the first detection means 22 does not detect the packaging box 11 (non-detection state). The box making machine 10 is controlled to operate. That is, in the box making machine 10, as shown in FIG. 2 or FIG. 3, the suction means 19 of the take-out device 18 moves forward and sucks the rear wall portion of the corrugated cardboard sheet 15 facing the sheet take-out position of the sheet magazine 16. By retracting the suction means 19 to the back standby position, one cardboard sheet 15 is taken out from the sheet magazine 16. At this time, the side wall of the corrugated cardboard sheet 15 abuts against the guide member 21 and the movement is restricted, so that the corrugated cardboard sheet 15 is opened in a box shape and taken out to the delivery position P1. In addition, when the foremost corrugated cardboard sheet 15 is picked up by the sucking means 19, the next corrugated cardboard sheet 15 is restricted from moving in the picking direction by the upper and lower restricting members 20, 20. The cardboard sheets 15 are prevented from being taken out in a state where they are overlapped. When the foremost cardboard sheet 15 is taken out, the transfer device 17 of the sheet magazine 16 is driven to move the next cardboard sheet 15 to the sheet takeout position and wait for the next takeout.

  The packaging box 11 taken out to the delivery position P1 by the take-out device 18 is sent out to the box conveyor 12 after the lower flap is folded, and at this time, the lower flap is sealed with a sealing tape. When the packaging box 11 assembled by the box making machine 10 is sent to the receiving position of the box conveyor 12, the first detection means 22 detects the packaging box 11, and the control means 23 is activated by inputting the detection signal. The box making machine 10 is controlled to interrupt the assembly of the packaging box 11 in the box making machine 10. When the packaging box 11 is conveyed from the receiving position to the downstream side by the processing on the downstream side of the box conveying conveyor 12 and the first detection unit 22 no longer detects the packaging box 11 again, the control unit 23 causes the box making machine 10 to The box making machine 10 is controlled so that the assembly of the packaging box 11 is resumed. In other words, the box making machine 10 is controlled to operate so that a predetermined number of packaging boxes 11 always stand by on the box transport conveyor 12, and the supply of the packaging boxes 11 to the storage standby position P2 can be prevented from being delayed.

  When the second detection means 24 detects that the packaging box 11 located on the most downstream side has arrived at the storage standby position P <b> 2 by the travel of the box conveyor 12, the control means 23 detects the detection signal from the second detection means 24. Is controlled so as to stop the box transport conveyor 12, whereby the packaging box 11 opened upward stops at the storage standby position P <b> 2 and waits for storage of the game board 13.

  An upper end portion of the game board 13 placed in a forward standing posture is supported on the board conveyor 14 by a support roller 25, and the game board 13 stands in a downstream posture by the running of the board conveyor 14. It is conveyed as it is. As shown in FIG. 9, when the detection signal that the third detection means 26 detects the game board 13 is input to the control means 23, the control means 23 controls the stop of the board conveyor 14, and the movable conveyor 29 The game board 13 is stopped on the upstream side. When the operation signal is input from the second operation switch 42, the control means 23 controls the board transport conveyor 14 to travel, and moves the game board 13 detected by the third detection means 26 to the movable conveyor 29. Transport toward

  The game board 13 sent from the board conveyor 14 to the movable conveyor 29 at the transfer position is conveyed downstream with the back surface of the upper end supported by the guide means 30, and the fourth detection means 34 is played. When the board 13 is detected, the control means 23 stops the movable conveyor 29 based on the input of the detection signal from the fourth detection means 34. At this time, as shown in FIG. 5, the right side surface (downstream end) of the game board 13 is brought into contact with the stopper 33a of the right guide 33 and the position is regulated, and the game board 13 is positioned at the box storage position P3. Further, since the upper surface of each support member 36 facing the support position of the support device 35 is located below the placement surface of the movable conveyor 29 at the transfer position, the game board 13 conveyed by the movable conveyor 29 is The conveyance is not hindered by contacting the support member 36. As described above, the game board 13 is supported by various parts arranged on the back side of the plate member 27 so that the center of gravity is located on the back side and the upper end on the back side is tilted to the guide means 30 side. 13 is stably conveyed by the movable conveyer 29 in a state where the back upper end of 13 is supported by the guide means 30. Further, as shown in FIG. 9, the left end of the left guide 32 is close to the most downstream support roller 25, so that the upper end of the game board 13 moving from the board transport conveyor 14 to the movable conveyor 29 is moved by the left guide 32. Continued support will ensure stable delivery.

  When the detection signal is input from the fourth detection unit 34, the control unit 23 controls the movable conveyor 29 and the left and right guides 32 and 33 to convey the movable conveyor 29 as shown in FIG. The left and right guides 32 and 33 are moved from the support position to the separated position while being lowered from the position to the lowered position. When the movable conveyor 29 moves from the transport position to the lowered position, the game board 13 is delivered to the pair of support members 36 and 36 that face the support position. As a result, the lower surface of the game board 13 is supported by the pair of support members 36, 36 inside the left and right ends, and the central portion of the upper end of the back side is supported by the middle guide 31. Both side surfaces are substantially exposed.

  With respect to the game board 13 whose lower surface is supported by the pair of support members 36, 36, the worker waiting at the work station pushes the lower wall portion 44 of the cushioning material 43 below the game board 13 from the front side. The left and right wall portions 45 and 46 are bent along the corresponding left and right side surfaces of the game board 13, and the lower surface and the left and right side surfaces of the game board 13 are surrounded by the cushioning material 43 ( (See FIG. 7). At this time, since the left and right guides 32 and 33 supporting the upper left and right sides of the game board 13 are retracted to the back side, the left and right walls 45 and 46 of the cushioning material 43 are connected to the left and right side surfaces of the game board 13. Can follow along without any problems. Further, even when the game board 13 is dropped from the support members 36 and 36 due to some cause during the work of disposing the cushioning material 43 on the game board 13 supported by the support members 36 and 36, FIG. As shown in (c), since the movable conveyor 29 is located below the support members 36, 36, the game board 13 is prevented from falling onto the box transport conveyor 12.

  In a state where the left and right wall portions 45, 46 of the cushioning material 43 surrounding the game board 13 in the box storage position P3 are held by holding the finger in the hand holes 47, 47, the operator operates the first operation switch with his / her foot. When 41 is operated, the control means 23 first controls the folding means 39 and moves the folding member 38 from the lower position to the upper position as shown in FIG. The support piece 44b formed on the portion 44 is bent so as to rise by the bending member 38, and the lower surface of the component 28 disposed on the back side of the game board 13 is supported by the support piece 44b. Next, the control means 23 controls the movable conveyor 29 and the support device 35 to move the movable conveyor 29 facing the lowered position to the retracted position and support the support members 36 and 36 of the support device 35 as shown in FIG. Move from position to release position. Since the recess 44a is formed in the lower wall portion 44 of the cushioning material 43 at a position corresponding to each support member 36, the support member 36 is smoothly moved from the support position to the release position. It is suppressed that the lower part of the game board 13 is moved to the back side together with 36. Further, since the back surface of the component 28 in the game board 13 is in contact with the restriction piece 37, the movement of the game board 13 to the back side is reliably prevented by the restriction piece 37. Displacement of the gaming board 13 from the box storage position P3 directly above the storage standby position P2 is suppressed. Since the bending of the support piece 44b by the bending means 39 is performed before the support of the game board 13 is released by the support device 35, it is not necessary for the operator to support the game board 13 at the time of bending, and the operator is burdened. It is possible to bend easily without applying a fold.

  When the support of the game board 13 by the support members 36, 36 of the support device 35 is released, the weight of the game board 13 is added to the buffer material 43, so that the operator can hold the left and right wall portions 45, 46 while holding the game board 13. By lowering the material 43, the cushioning material 43 and the game board 13 are stored from above in the packaging box 11 facing the storage standby position P2, as shown in FIG. In the game board 13 surrounded by the cushioning material 43, the lower surface of the component 28 disposed on the back side is supported by the support pieces 44 b, and the left and right ends of the plate member 27 are the left and right wall portions 45, 46 of the cushioning material 43. Therefore, when the game board 13 is stored in the packaging box 11, it is prevented that the game board 13 moves and hinders the storage. Further, since the impact generated when the lower surface of the cushioning material 43 reaches the inner bottom surface of the packaging box 11 can be absorbed by the support piece 44b, damage to the component 28 and the like can be prevented. Further, the outer dimension of the lower wall portion 44 of the cushioning material 43 in a state of surrounding the game board 13 is set to be slightly smaller than the opening dimension of the packaging box 11, and the cushioning material 43 and the packaging box 11 together with the gaming board 13 are set. When stored in the packaging box 11, the air in the packaging box 11 is difficult to escape due to the small gap between the cushioning material 43 and the packaging box 11. The impact generated when the lower surface of the material 43 reaches the inner bottom surface of the packaging box 11 can be reduced. That is, since the shock itself generated when the lower surface of the cushioning material 43 reaches the inner bottom surface of the packaging box 11 can be reduced, the damage of the component 28 and the like can be surely combined with the impact absorbing action of the support piece 44b. Can be prevented.

  When the operator operates the second operation switch 42, the control means 23 controls the movable conveyor 29 and the support device 35 to move the movable conveyor 29 facing the retracted position to the transport position and to support it. The support members 36 and 36 of the device 35 are moved from the release position to the support position. Further, both the left and right guides 32 and 33 are controlled by the control means 23, the both guides 32 and 33 move from the separated position to the support position, and wait for the next game board 13 to be loaded (state of FIG. 4). Then, the control means 23 controls the fourth box 34 to run on the board box conveyor 14 under the non-detection condition, and conveys the game board 13 on the most downstream side toward the movable conveyor 29. . Further, the box transport conveyor 12 is controlled to travel, the packaging box 11 containing the game board 13 is carried out to the sealing machine 40, and the upper flap of the packaging box 11 is folded and sealed with a sealing tape.

  As described above, the game board 13 is supplied to the box storage position P3 above the storage standby position P2 where the packaging box 11 that opens upward is waiting, and the cushioning material 43 is arranged on the game board 13 at the box storage position P3. The game board 13 surrounded by the cushioning material 43 can be stored in the packaging box 11 simply by releasing the support of the game board 13 and lowering it as it is. That is, the operator does not need to lift the game board 13 surrounded by the cushioning material 43 to a position where it can be stored in the packaging box 11 from above, so that the burden on the operator can be reduced and work efficiency can be improved.

[Second Embodiment]

Only the part will be described. In addition, since the apparatus configuration is not different between the first embodiment and the second embodiment, the same reference numerals are given to the same members in both embodiments.

  In the packaging line of the second embodiment, when the detection signal from the fourth detection means 34 is input, the control means 23 moves the movable conveyor 29 and the game board 13 from the transfer position to the support members 36 and 36. Control is performed so as to move back to the retracted position after being lowered by a transferable height. That is, in the packaging line of the second embodiment, when the game board 13 is detected by the fourth detection means 34, the movable conveyor 29 moves to the retracted position as shown in FIG. The guides 32 and 33 are configured to move to the separated position. By retracting the movable conveyor 29 from the lower side of the game board 13 in this way, a large space is created below the game board 13, and the work of disposing the cushioning material 43 on the game board 13 is facilitated.
