(See FIG. 3D). Further, the wrapping paper 12 on the top surface of the article 10 is bumped by the folding members 33 and 33 being lowered with the extending portions 16 and 17 sandwiched from the front and the back and pressed against the front and rear surfaces of the article 10. The front and rear extending portions 16 and 17 are pressed against the front and rear surfaces of the article 10 (see FIG. 3E). As a result, as shown in FIG. 4A, the packaged product 18 in which the article 10 whose bottom surface is supported by the folding unit S2 is covered with the wrapping paper 12 includes the first folding member 20 and the second folding member 20 positioned at the retracted position. Between the folding member 21, the second extending portion 17 and the first extending portion 16 face downward from the front and rear lower edges of the article 10.

  By moving the first folding member 20 positioned at the retracted position horizontally (see FIG. 4B), the first extending portion 16 extending downward from the rear lower end edge of the article 10 becomes the article 10. Folds along the bottom of the. After the first folding member 20 that has folded the first extending portion 16 moves forward to the folding position and stops, the second folding member 21 located at the retracted position approaches the first folding member 20. The second extending portion 17 extending downward from the front lower end edge of the article 10 is folded along the bottom surface of the article 10 by moving forward horizontally. The second extending portion 17 folded by the proximity movement of the second folding member 21 toward the first folding member 20 overlaps the first extending portion 16 extending from the tip of the second folding member 21, By retracting the first folding member 20 toward the retracted position so as to synchronize with the second folding member 21 at the timing when the overlapping portion T1 is supported by the second folding member 21, both folding members 20, 21 Move with their tips close together. As a result, the second extension portion 17 folded by the second folding member 21 is overlapped on the front side of the first extension portion 16 that has been folded first, and the article 10 is covered with the wrapping paper 12. 18 is obtained.

  When the first folding member 20 is retracted to the retracted position and the second folding member 21 is advanced to a passing position where the hooking member 22 passes under the packaged product 18, the hooking member 22 at the retracted position is reached. Is raised to the hooking position (see FIG. 4C). Next, by retracting the second folding member 21 toward the retracted position, the hooking member 22 moved to the hooking position is hooked on the rear end edge of the packaged product 18, and the second folding member 21 is moved. The packaged product 18 placed on is horizontally transferred to the sealing portion S3 (see FIG. 4D). Further, the packaged product 18 placed and transferred on the second folding member 21 from the folding portion S2 toward the sealing portion S3 is pressed against the second folding member 21 from the top surface side by the top surface guide 41. Is done. Then, in the packaged product 18 that has been transferred to the sealing portion S3, the overlapping portion of the two extending portions 16 and 17 of the wrapping paper 12 folded at the bottom is sealed by a predetermined sealing means 19.

  In the packaging product transfer apparatus of the embodiment, the packaging product 18 is directed toward the sealing portion S3 by the hook member 22 that moves integrally with the second folding member 21 that folds the second extending portion 17 of the wrapping paper 12. Since it is configured to transfer, it is not necessary to provide a transfer conveyor provided with an extrusion member above the transfer path of the packaged product 18, and the apparatus can be reduced in size, and from the folding of the extension portion 17 to the transfer. It can be carried out stably. Moreover, since the hook member 22 moves integrally with the second folding member 21 on which the packaged product 18 is placed, the hooking member 22 is packaged on the bottom surface of the packaged product 18 placed on the second folding member 21. The package 18 can be stably transferred toward the sealing portion S3 without loosening the folding of the paper 12. In addition, with a simple configuration that simply raises and lowers the hooking member 22, the second folding member 21 can fold the second extending portion 17 and stably transfer the packaged product 18 to the sealing portion S <b> 3. it can. Furthermore, since the top surface guide 41 for pressing the package product 18 from the top surface side is provided above the transfer path of the package product 18, the package product 18 is stably transferred from the folding portion S2 to the sealing portion S3. can do. Further, it is possible to suppress the looseness of the wrapping paper 12 during the transfer.

  Since the first folding member 20 and the second folding member 21 are configured to move horizontally at the same horizontal level, the second folding member 20 is in close contact with the first extending portion 16 folded by the first folding member 20. The extending part 17 can be folded by the second folding member 21. In addition, the first folding member 20 obtained by folding the first extending portion 16 along the bottom surface of the article is overlapped on the first extending portion 16 by folding the second extending portion 17 with the second folding member 21. In this case, since the second folding member 21 is configured to move backward while supporting the overlapping portion T1 of the first extending portion 16 and the second extending portion 17, the first extending portion folded first. 16 can be effectively prevented from being pulled back and loosened by the retraction of the first folding member 20. In addition, it is possible to prevent the overlapping of the extending portions 16 and 17.

  The hooking member 22 is configured to move up and down between the retracted position and the hooking position by the lifting and lowering air cylinder 23 that moves integrally with the second folding member 21. 2 In relation to the folding operation of the extending portion 17, the raising / lowering timing of the hooking member 22 can be freely set, and the adjustment at the time of packaging a plurality of types having different article dimensions can be simplified. Moreover, since each folding member 20 and 21 was moved independently by the servomotors 39 and 40 which moved the 1st folding member 20 and the 2nd folding member 21 separately, each folding member 20 , 21 can be arbitrarily changed and set. That is, since the folding timing of the wrapping paper 12 by the folding members 20 and 21 can be arbitrarily changed and set, the article 10 having a different material and size of the wrapping paper 12 and other conditions can be flexibly dealt with, and it can be used for a wide variety of products. Can be easily performed.

The present invention is not limited to the configuration of the embodiment, and can be modified as follows, for example. Further, not limited to the following modification examples, various embodiments may be adopted for the configurations described in the examples within the scope of the gist of the present invention.
(1) The hooking member 22 is configured to move up and down by an elevating air cylinder 23 that moves integrally with the second folding member 21. However, the hooking member 22 is moved up and down by other driving means such as a motor. Can do. In addition, the driving means of the switching operation means is arranged in an appropriate fixing portion, and the linkage mechanism that links the driving means and the hooking member 22 is operated by the driving means at a timing related to the folding operation of the second folding member 21. It is possible to employ a configuration that operates to move the hooking member 22 between the retracted position and the hooking position. Further, when the extension portion 17 is folded without using a driving means, it is separated from the packaged product 18 by an elastic member such as a spring and moves to the hooking position after passing through the packaged product 18, and a cam and a cam follower are used. Such as a structure in which the hook member 22 is moved up and down by a cam link mechanism or the like according to the movement mechanism of the mechanism or the second folding member 21 at a position where the extension portion 17 is separated from the packaged product 18 and does not interfere with Various mechanisms that project toward the packaged product 18 after the extension portion 17 is folded and can move to a position where the packaged product 18 can be hooked and pushed can be employed as the switching operation means.
Further, the hooking member 22 is not limited to linearly moving up and down by a switching operation means such as a driving means or a cam link mechanism, but is directed to a retracted position separated from the packaged product 18 by a rotary type or the like and to the packaged product 18. It is possible to employ a configuration that moves between the hook positions projecting.
(2) The second folding member 21 is moved from the folding height position of the first folding member 20 so that the folding heights (horizontal movement levels) of the first folding member 20 and the second folding member 21 are different. It is possible to adopt a configuration in which horizontal movement is performed at a position away from the article 10. Further, when the first folding member 20 is retracted in a state where the overlapping portion T1 of both the extending portions 16 and 17 is supported by the second folding member 21, the first folding member 20 retracts faster than the moving speed of the second folding member 21. May be.
(3) Although the first folding member 20 and the second folding member 21 are moved forward and backward by driving the servo motors 39 and 40, they are driven by another actuator such as an air cylinder or a cam link mechanism. May be.
(4) Not only the form which folds the extension parts 16 and 17 under the article | item 10, but the form which folds a pair of extension parts 16 and 17 extended upwards from the upper end edge which the article | item 10 opposes above the article | item 10. Can be adopted. That is, the second folding member 21 moves forward and backward at the same height level as or above the first folding member 20 that moves forward and backward over the package 18 whose lower surface is supported by the folding part S by the support means. When the second extension member 17 is folded by the second folding member 21, the hook member 22 positioned at the retracted position is lowered to the hook position after the second extension portion 17 is folded. It is possible to adopt a configuration in which the packaged product 18 is hooked by the hooking member 22 by the retraction of the two folding members 21 and the packaged product 18 supported by the supporting means is pushed.
(5) In the embodiment, the sealing part S3 for sealing the front and rear extension parts 16, 17 folded on the bottom surface of the article is used as the next processing part, but the packaged product 18 after packaging is removed from the upper packaging machine. It is good also considering the carrying-out part to carry out as the following process part.
