In the process in which the article 10 is lifted by the lifter 14, the top surface of the article 10 is pushed up onto the wrapping paper 12 from below and the wrapping paper 12 is pressed against the top surface of the article 10 by the weight of the pressing member 26. By rising, the wrapping paper 12 is lifted with respect to the article 10 without being displaced.

前記一対の折曲げガイド２４,２４の間を物品１０が押し上げられる際に、該物品１０の天面にあてがわれた包装紙１２は、該物品１０の左右の端縁から外方に延出する左右の延出部１５,１５が物品１０の左右の側面に沿って下側に向けて折り曲げられる。前記折畳み位置Ｓ２まで持ち上げられた物品１０の底面が支持され、包装紙１２の左右の延出部１５,１５が、折込手段２７の折込片２８,２８によって物品１０の前面と後面に沿うよう折り込まれると共に、底折り手段２９の折曲片３０,３０によって物品１０の底面に沿って折り曲げられる(図３(ｂ),(ｃ)参照)。また、物品１０の前後の端縁から外方に延出する包装紙１２の前後の延出部１６,１７が、前後折曲手段３２の折曲部材３３,３３によって物品１０の前後面に沿って折り曲げられる(図３(ｄ)参照)。更に、前記折曲部材３３,３３が延出部１６,１７を前後から挟んで物品１０の前面と後面に押し付けた状態で下降することにより、物品１０の天面の包装紙１２がだぶつくことなく密着状態となり、前後の延出部１６,１７が物品１０の前後面に密着するように押し当てられる(図３(ｅ)参照)。これにより、図４(ａ)に示す如く、折畳み部Ｓ２で底面が支持状態の物品１０を包装紙１２で覆った包装品１８は、前記退避位置に位置する第１折畳部材２０および第２折畳部材２１の間に、物品１０の前後の下端縁から第２延出部１７および第１延出部１６が下方に延出する状態で臨む。   When the article 10 is pushed up between the pair of bending guides 24, 24, the wrapping paper 12 applied to the top surface of the article 10 extends outward from the left and right edges of the article 10. The left and right extending portions 15, 15 are bent along the left and right side surfaces of the article 10 downward. The bottom surface of the article 10 lifted up to the folding position S2 is supported, and the left and right extending portions 15 and 15 of the wrapping paper 12 are folded along the front and rear surfaces of the article 10 by the folding pieces 28 and 28 of the folding means 27. At the same time, the bent pieces 30 and 30 of the bottom folding means 29 are bent along the bottom surface of the article 10 (see FIGS. 3B and 3C). Further, the front and rear extending portions 16 and 17 of the wrapping paper 12 extending outward from the front and rear edges of the article 10 are formed along the front and rear surfaces of the article 10 by the folding members 33 and 33 of the front and rear folding means 32. (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.

前記退避位置に位置する第１折畳部材２０を水平に前進することで(図４(ｂ)参照)、前記物品１０の後下端縁から下方に延出する第１延出部１６が物品１０の底面に沿って折り畳まれる。第１延出部１６を折り進んだ第１折畳部材２０が折畳み位置まで前進して停止した後に、前記退避位置に位置する第２折畳部材２１を第１折畳部材２０に接近するように水平に前進することで、前記物品１０の前下端縁から下方に延出する第２延出部１７が物品１０の底面に沿って折り畳まれる。第２折畳部材２１の第１折畳部材２０に向けた近接移動により折り畳まれる第２延出部１７が第２折畳部材２１の先端から延出する第１延出部１６に重なり、その重合部Ｔ１を第２折畳部材２１で支持したタイミングで第１折畳部材２０を第２折畳部材２１と同調するように退避位置に向けて後退することで、両折畳部材２０,２１は先端同士が近接した状態で移動する。これにより、先に折り畳まれている第１延出部１６の表側に、第２折畳部材２１で折り畳まれる第２延出部１７が重ねられ、包装紙１２で物品１０が覆われた包装品１８が得られる。   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.

前記第１折畳部材２０が退避位置まで後退すると共に、前記引掛け部材２２が包装品１８の下方を通過する通過位置まで第２折畳部材２１が前進すると、前記退避位置の引掛け部材２２が引掛け位置まで上昇される(図４(ｃ)参照)。次いで、前記第２折畳部材２１を退避位置に向けて後退することで、引掛け位置まで移動された引掛け部材２２が包装品１８の後端縁部に引掛かり、第２折畳部材２１に載置されている包装品１８は封止部Ｓ３まで水平に移送される(図４(ｄ)参照)。また、折畳み部Ｓ２から封止部Ｓ３に向けて第２折畳部材２１に載置されて移送される包装品１８は、前記天面ガイド４１によって天面側から第２折畳部材２１に押圧される。そして、封止部Ｓ３まで移送された包装品１８は、底面で折り重なった包装紙１２の両延出部１６,１７の重なり部が所定の封止手段１９によって封止される。   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.

実施例の包装品移送装置では、包装紙１２における第２延出部１７を折り畳む第２折畳部材２１と一体的に移動する引掛け部材２２によって、包装品１８を封止部Ｓ３に向けて移送するよう構成したので、包装品１８の移送路の上方に押出し部材を備えた移送コンベヤを設ける必要はなく、装置の小型化を図ることができると共に、延出部１７の折り畳みから移送までを安定して実施することができる。また、引掛け部材２２は、包装品１８が載置されている第２折畳部材２１と一体的に移動するので、第２折畳部材２１に載置された包装品１８の底面での包装紙１２の折り重ねが緩むことなく、包装品１８を封止部Ｓ３に向けて安定的に移送することができる。また、引掛け部材２２を昇降するだけのシンプルな構成で、第２折畳部材２１による第２延出部１７の折り畳みと包装品１８の封止部Ｓ３への安定した移送を達成することができる。更に、包装品１８の移送路の上方に、該包装品１８を天面側から押圧する天面ガイド４１を設けているので、折畳み部Ｓ２から封止部Ｓ３に包装品１８を安定して移送することができる。また、移送中に包装紙１２に緩みが生ずるのを抑制することもできる。   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.

前記第１折畳部材２０および第２折畳部材２１を同一水平レベルで水平移動するよう構成したので、第１折畳部材２０で折り畳まれた第１延出部１６に密着するように第２延出部１７を第２折畳部材２１で折り重ねることができる。また、前記第１延出部１６を物品底面に沿って折り畳んだ第１折畳部材２０を、前記第２折畳部材２１で第２延出部１７を折り畳んで第１延出部１６に重ねる際には、第２折畳部材２１で第１延出部１６と第２延出部１７との重合部Ｔ１を支持した状態で後退するよう構成したので、先に折り畳んだ第１延出部１６が、第１折畳部材２０の後退によって引き戻されて緩むのを効果的に防止できる。また、両延出部１６,１７の折り重ねのだぶつきを防止できる。   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.

前記引掛け部材２２は、前記第２折畳部材２１と一体的に移動する昇降用エアシリンダ２３によって退避位置と引掛け位置とに昇降動するよう構成したので、第２折畳部材２１による第２延出部１７の折り畳み動作に関連して、引掛け部材２２の昇降タイミングを自由に設定することができ、物品寸法が異なる複数品種の包装時の調節を簡単にすることができる。また、第１折畳部材２０と第２折畳部材２１とを別々に移動するサーボモータ３９,４０により各折畳部材２０,２１を独立して移動するよう構成したので、各折畳部材２０,２１の移動位置や移動速度を任意に変更設定することができる。すなわち、折畳部材２０,２１による包装紙１２の折り曲げタイミングを任意に変更設定できるので、包装紙１２の材質やサイズの異なる物品１０、その他の条件変化に柔軟に対応でき、多品種への対応を容易に行うことができる。   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.
