The packaging machine 10 of the cardboard boxing system 1 is a vertical bag packaging machine that manufactures a bag package by packaging the product S in a cylindrical packaging material. 11 is bent into a cylindrical shape, both side edges are heat-sealed by a vertical heat sealer 13 and formed into a cylindrical packaging material Ft around the filling cylinder 12, and the product S put into the filling cylinder 12 is packaged in a cylinder By filling the material Ft, and heat-sealing the cylindrical packaging material Ft with the horizontal heat sealer / cutter 14 above and below the product S and cutting with the cutter, a bag package P such as a pillow package is manufactured. It is a vertical type bag making filling and packaging machine that may be known. The packaging machine 10 is installed with its lower end close to the floor surface. A curved chute 15 is provided below the horizontal heat sealer / cutter 14, and the back-sealed seal portion Sb heat-sealed by the vertical heat sealer 13 changes its direction to the upper surface and is discharged from the packaging machine 10. . The packaging machine 10 includes a roll loading unit 16 in which a web roll Rw around which a web-shaped packaging material Fw is wound is loaded.

  Here, the definition about the attitude | position of the bag packaging body P and the cardboard box B is demonstrated. In the bag package P shown on the left side of FIG. 5 (a), a vertical heat seal portion (back-attached seal portion) is present on the lower side of the bag, and the surface Pa that is often subjected to printing representing products etc. is the upper surface. Shows the state of facing. The bag packaging body P shown on the right side of FIG. 5A is opposite to that shown on the left side, and shows a state where the back-sealed seal portion Sb exists on the upper side of the bag. FIG. 5 (b) shows a state in which the cardboard box is in a normal top-and-bottom position, and the upper figure shows a sealed state (cardboard box B4) with the flap fb of the cardboard box B closed. The figure on the side shows that the flap fb is in an unsealed state (corrugated cardboard boxes B2 and B3).

As shown in detail in FIG. 3, the upward inclined conveying conveyor 20 that conveys the bag package P manufactured by the packaging machine 10 has the lowest height at the carry-in position 22 that receives the bag package P from the curved chute 15, After receiving the bag package P, it gradually rises as it is transported , and as a front stage of the up-tilt transport conveyor 20 , a series of slopes leading to an intermediate position 23 for feeding the bag package P into the cardboard caser 40 A conveyance path 21 is provided. In the ascending and conveying conveyor 20, the bag packaging body P is in a state where the back-sealed seal portion Sb faces the upper surface, and the lower end portion of the bag filled with the product S in the packaging machine 10 is forward in the conveying direction (upward direction). It is transported in the state of facing. A weight checker 24 is disposed along the inclined conveyance path 21. The weight checker 24 measures the weight of each bag package P and checks whether the weight is within an allowable range. A height measuring device 25 for measuring the height of each bag package P is disposed immediately downstream of the position where the weight checker 24 of the inclined conveyance path 21 is disposed. The height measuring device 25 measures the height of each bag package P and checks whether the height is within an allowable range. The bag package P whose weight or height is outside the allowable range is immediately discharged out of the conveyor so as not to be carried into the cardboard caser 40.

  As shown in FIG. 3, the bag package P manufactured by the packaging machine 10 has the product S by the packaging machine 10 with the side with the back-sealed seal portion Sb facing the upper surface, that is, the upper side of the bag package P. During manufacture in which the bag is filled, the bag end on the bag bottom side is directed forward in the conveyance direction, and is conveyed so as to ascend the conveyance path that has become the upward inclined path of the upward inclined conveyance conveyor 20 (state (I) ). Therefore, the product S that has been sunk to the bottom during the manufacture of the bag package P in the packaging machine 10, that is, the product S that is biased forward in the conveyance direction, is transferred when it is transferred to the upward inclined conveyor 20. The direction of is greatly changed, acceleration is applied to the product S, and it naturally moves back in the bag and is leveled (shown in the state of (II)). The bag package P is packed in a corrugated cardboard box B2 that has been formed in an inverted state with the shape of the product S in the bag being free from unevenness.

  About the conveyance speed of the upward inclination conveyance conveyor 20, it can be made variable. By changing the conveyance speed of the upward inclined conveyance conveyor 20, the magnitude of the acceleration received by each bag package P during conveyance changes, and the product S that is unevenly distributed in the conveyance direction in the bag changes such acceleration. In response, the degree of movement in the bag, that is, the leveling condition can be changed. Specifically, the level of the product S at the time of transfer to the up-tilt transport conveyor 20 can be increased as the transport speed of the up-tilt transport conveyor 20 is made larger than the speed of sliding down the curved chute 15. By smoothing, the bag package P in a state close to a fixed shape is stably accumulated, stably inserted into the cardboard box B2, packed in a box, and then sealed.

In the corrugated cardboard boxing system according to the present invention, a direction changing device and a sorting device for the bag packaging are arranged on the downstream side of the intermediate position 23 of the upward inclined conveying conveyor 20, and after the sorting device of the conveying conveyor 20. Connected to the stream is a gathering device for bag packaging. That is, the conveyor 20 is configured as an upwardly inclined conveyor that includes the inclined conveyor path 21 and is provided with a direction changing device and a distribution device, and is configured to follow the upstream inclined conveyor. The collective device is connected in a horizontal state. 9 and 10 are a side view and a top view showing the sorting device and the gathering device of the cardboard boxing system 1, and the sorting device 201 shown on the left side of the figure is a first transporting bag package from the intermediate position 23 in a row. Between the supply conveyor 202 as one conveyance device, the alignment conveyor 203 as a second conveyance device that distributes and discharges the bag package supplied from the supply conveyor 202 in two rows, and between the supply conveyor 202 and the alignment conveyor 203 And a sorting conveyor 204 as a sorting device that sorts the bag package into two rows (a plurality of rows; here, two rows). Each of the conveyors 202, 203, and 204 is a belt conveyor that is driven by a motor and forms a gently rising conveyor row, and the distribution device 201 is a rear stage of the upward inclined conveying conveyor 20, that is, after the direction changing device. It constitutes the rearmost part of the upwardly inclined conveying conveyor on the flow side and on the upstream side of the collecting device .

  The supply conveyor 202 sequentially conveys the bag packages in a row and spaced from each other. The sorting conveyor 204 is reciprocated along the slide shafts 207 and 207 when the output of the servo motor 205 is converted into a lateral movement perpendicular to the conveying direction via the crank mechanism 206. The sorting conveyor 204 crosses the transport direction of the bag package in the transverse direction while preferably transporting the bag package conveyed in a row from the supply conveyor 202 by reciprocation between the sorting transfer positions (preferably Moves toward the sorting and transfer position that is orthogonal to the carrying direction of the bag package, and transfers the carried bag package to the alignment conveyor 203 at the sorting and transferring position. That is, the bag package is distributed to the two alignment conveyors 203a and 203b at the two distribution transfer positions which are the dead center positions when moving most in the horizontal direction on the distribution conveyor 204. The alignment conveyor 203, which is the second transport device, is composed of two rows of alignment conveyors 203a and 203b. The alignment conveyor 203a is a continuously driven belt conveyor, and the alignment conveyor 203b is an intermittently driven belt conveyor.

A moving / converting mechanism 214 is provided that moves the suction units 213 and 213 in synchronization with the transport of the supply conveyor 202 by the driving force from the mechanism 212 to change the direction while transporting the sucked product.

  In the driving mechanism 212 of the direction changing device 210, the output of the servo motor attached to the frame 211 is transmitted to the moving / converting mechanism 214 via the belt transmission mechanism. The movement / conversion mechanism 214 causes the suction units 213 and 213 attached to the chain to move in parallel along the winding path by the two front and rear chain transmission mechanisms 215 and 215. Since the cam mechanism 216 is combined with one of the chain transmission mechanisms 215, the suction units 213 and 213 rotate around the axis of each unit together with the parallel operation to rotate the sucked bag packaging body. Let the direction of the bag package change.

In the downstream of the alignment conveyor 203, a bag package is used as a collective conveying device that collects the bag package conveyed by the uphill conveying conveyor 20 and conveys the assembled bag package group to the bag package input unit. The collective device 220 is provided. As shown in FIG. 12, the collecting device 220 is configured based on two sets of table conveyors 221 and 222 including chains 223 and 224 and slat-like collecting tables 225 and 226 attached thereto. The slat-like gathering tables 225 and 226 are configured by attaching elongated plates next to each other over the chain. A partition plate can be erected on the elongated plate so that the products can be assembled in an upright state. Each table conveyor 221, 222 has a chain sprocket at both ends coaxially arranged, and is driven by separate servo motors 227, 228 so as not to interfere with each other. Set table 225 and 226, the elongated plate adjacent when traveling on a curved path, such as around the chain sprocket can pass through the curved road by bending relative to one another. The table conveyors 221 and 222 can place the bag package P on the collective tables 225 and 226. That is, the bag package P carried out from the aligning conveyor 203 is moved in small increments by moving the collecting tables 225 and 226 in a small amount, or is gathered on the collecting tables 225 and 226 in a sash-like manner or gathered in a flat state. It becomes a state.

In the table conveyors 221 and 222, a bag packaging input device 230 is disposed downstream of the collecting device 220 (corresponding to the cardboard caser 40 including the boxing station 41 in FIGS. 1 and 2). The assembling apparatus 220 conveys the bag packaging body group that is in the gathering state on the assembling table 225 or 226 to a bag packaging body loading section provided at a position corresponding to the bag packaging body loading apparatus 230. The product loading device 230 has a structure that also serves as a gripping device provided with a gripping tool 231 formed of a suction cup, and sucks and grips the bag package group that is gathered in a sash-like shape or a flat place on the gathering tables 225 and 226. Can be raised and lowered. When the gripping tool 231 sucks and grips the bag packaging body group on the assembly table 225 or 226 conveyed to the bag packaging body input section , the table conveyors 221 and 222 are driven, and the assembly table 225 or 226 becomes the bag packaging body input section. Get away from. There is no aggregate table 225, 226 below the input device 230, and the input device 230 descends through the empty space of the table conveyors 221, 222 by the operation of an appropriate drive mechanism 232 using a servo motor. It is, that beneath, i.e., is introduced into a cardboard box that is conveyed to the insertion of the box conveyor device (described in detail below). The lowering amount (speed and position) of the charging device 230 can be controlled in accordance with the input amount (input amount) of the bag package into the cardboard box.

  The corrugated cardboard box in which the bag package group has been charged is lightly tapped or vibrated by the vibration mechanism 240, or the top product in the cardboard box is pressed by the press mechanism 250. By pressing at 251, the degree of product accumulation in the box can be made denser. Folding the flap that was open at the top at the loading position, and further sealing the flap with tape or adhesive, completes the packaging of the product.

  The cardboard box box making machine 30 unfolds and forms a folded cardboard box, and is disposed adjacent to the side of a cardboard caser 40 described later. The corrugated cardboard boxes B1 folded in the stacker 31 and accumulated in a stack are fed out one by one by the suction means 32, etc., and folded at a molding station 33 at a right angle to form a box (corrugated cardboard). Box B2). In this cardboard box box making machine 30, the cardboard box B1 is set upside down, and the flap on the top side is originally folded and sealed with tape. Is set to the open state. The cardboard box molded in a predetermined unfolded state at the molding station 33 is pushed out to the feeding station 34 by an appropriate means (such as a pusher), and passes through the transfer path 35 from the feeding station 34 to the boxing station 41 of the cardboard caser 40.
