  The main body C1 of the case C is held by a case holding portion 262 provided in the case rotating device 26. The case holding part 262 can be rotated approximately 90 ° by a rotation mechanism described later. In FIG. 3, the case C is laid sideways and its opening is directed to the pusher moving endless belt 180 side, and the packaging start position of the case holding portion 262 is rotated approximately 90 ° from the sideways state. Thus, the boxing completion position of the case holding part 262 whose opening is directed upward is drawn.

  The case holding part 262 includes a plate part 262P that is in close contact with one side surface (the side surface on the near side in FIG. 3) of the case main body C1 and sucks the case C. Further, from the lower side of the plate portion 262P at the packaging start position, the plate portion 262P is bent to the back side of the drawing, and the lower folded portion 262B that supports the lower side of the case body C1 at the packaging start position, and the plate portion 262P in FIG. A rear folded portion 262R that is bent from the left side at the packaging start position to the back side of the drawing and contacts the rear side of the case main body C1 at the packaging start position is provided.

  The case C is delivered to the case holding part 262 disposed at the boxing start position using, for example, case delivery means (not shown), and is sucked and held by the plate part 262P. The case holding portion 262 is held by a cylinder 264 that can advance and retreat in the direction perpendicular to the paper surface of FIG. 3, and the cylinder 264 is held by the arm movable portion 266. The arm movable portion 266 can advance and retreat with respect to the arm base portion 268 (can advance and retreat in the left-right direction at the boxing start position in FIG. 3).

  The arm base 268 is pivotally supported on the lifting block 270 via a pivot shaft 268P (a horizontal axis perpendicular to the longitudinal direction of the pusher moving endless belt 180) arranged along the direction perpendicular to the paper surface of FIG. Further, the swing arm 272 to which the base end portion is attached can be rotated with respect to the lifting block 270. That is, the case holding portion 262, the cylinder 264, the arm movable portion 266, and the arm base portion 268 can be integrally rotated about 90 ° about the pivot shaft 268P.

A cam follower 272C is provided at the tip of the swing arm 272, and the cam follower 272C engages with a cam groove 275 extending along a horizontal axis (lateral direction in FIG. 3) parallel to the rotation surface of the swing arm 272. . Therefore, the movement of the tip portion of the swing arm 272 is restricted to the horizontal reciprocation along the cam groove 275. When the elevating device 274 is driven and the elevating block 270, that is, the pivot shaft 268P is moved up and down, the cam follower 272C provided at the tip of the swing arm 272 is moved in the cam groove 275, thereby the arm base 268, That is, the case holding part 262 rotates around the pivot shaft 268P while moving up and down. When the elevating block 270 is at the upper limit position in the elevating movable range, the case holding portion 262 is arranged at the upper packaging start position at the upper side, and when at the lower limit position, it is arranged at the lower packaging completion position at the lower limit position.

  When the case C is transferred to the case holding portion 262, the lid C2 of the opening of the case C is opened, and the tip portions of the pair of side guides 22 and 22 are placed in the case C as shown in FIG. Is inserted into the main body C1. The side guides 22 and 22 include a pair of upright plate-like members arranged in parallel along the pusher moving endless belt 180 from the stacking device 16 toward the case holding portion 262 at the boxing start position. . Immediately after the case C is delivered to the case holding portion 262, the side guides 22 and 22 are brought close to each other so that the front ends of the side guides 22 and 22 inserted into the case main body C1 do not contact the case main body C1. After that, when the tip portion is inserted into the case main body C1, it is expanded so as to be separated from each other (opened in the direction perpendicular to the paper surface of FIG. 1). As a result, the outer surfaces of the side guides 22 and 22 abut against the inner sides of the two opposing side surfaces of the case C1 at the opening, and the case C is maintained in an appropriate opening state.

  In FIG. 1, a lid C2 (see FIG. 3) is provided at the side opening located on the back side of the case body C1, and the back side guide 22 maintains the lid C2 in an open state. Also fulfills. Further, the case C of the present embodiment includes flaps on both side surfaces (upper and lower side surfaces in FIG. 1) of the side surface provided with the lid C2, and these flaps are respectively provided by an upper flap guide 24U and a lower flap guide 24D. Maintained open. In addition, when in the packaging start position, the lower surface of the case C is positioned at substantially the same height as the endless belts 180, 182, and 182 and slightly lower than the guide plates 194 and 194.

  That is, in parallel with the insertion of the front ends of the side guides 22 and 22 into the case C, the upper flap guide 24U is swung upward, and the upper flap in FIG. 1 is flipped upward by the upper flap guide 24U. Further, the lower sides of the tip portions of the side guides 22 and 22 have a tapered shape such that the tip ends of the side guides 22 and 22 are narrowed, and the horizontal lower sides behind the taper portions are perpendicular to the plane of FIG. Are provided with a lower flap guide 24D composed of tongue members bent in an L shape inside each other. When the front ends of the side guides 22 and 22 are inserted into the case C, the lower flap guide 24D comes into contact with the lower flap, and the lower flap is pushed down.

  Note that the case C is transferred to the case holding portion 262 by bringing the case C held at a predetermined position by case transfer means (not shown) into close contact with the case holding portion 262 from the side of the case C by driving the cylinder 264. This is performed by adsorbing the case C by an adsorbing means (not shown). The insertion of the distal ends of the side guides 22 and 22 into the case C drives the arm movable portion 266 to horizontally move the case C held by the case holding portion 262 toward the pusher moving endless belt 180 side. Is done. Here, the lower folded portion 262B and the rear folded portion 262R provided on the plate portion 262P are engaged with the corresponding surfaces of the case C to prevent misalignment when the case is attracted and when the side guide is inserted. Further, when receiving the next case C, the arm movable portion 266 and the cylinder 264 are driven in reverse to return the case holding portion 262 to the original position.

  Next, with reference to FIG. 2, the operation of the stacking process for the articles W in the stacking apparatus 16 will be described.

  In the embodiment shown in FIG. 2, the stacking device 16 stacks ten articles W in units, and packs the stacked articles W into each case C. FIG. 2 shows a state in which the first set of stacking has been completed, and four of the next set have been put into the stacking device 16 from the article supply conveyor 12 (see FIG. 1).

  The lowermost (first stage) article W among the ten articles W of the set in which the stacking has been completed is placed on the guide plates 194 and 194 of the stacked article extrusion apparatus 18. At this time, the finger pairs 16F and 16F that have supported the first-stage article W and transported downward between the opposing spans are moved to the span between the sprockets 163 and 164.

  Four (second to fifth stage) articles W stacked on the first stage article W are supported from both sides by the lowest pair of fingers 16F and 16F in the opposing span. Further, four (6th to 9th stage) articles W stacked thereon are supported from both sides by finger pairs 16F and 16F located second from the bottom in the opposing span. The uppermost (tenth stage) article W in this set is supported by the pair of fingers 16F and 16F located third from the bottom in the opposing span.

  Also, in the illustrated example, the fourth finger pair 16F, 16F positioned from the bottom in the opposing span is not used, and the fifth pair of finger pairs 16F, 16F includes only one one-stage article W in the next set. A state in which three (2nd to 4th stage) articles W are stacked on the pair of fingers 16F and 16F that are supported and located at the sixth position from the bottom of the opposing span is shown. In the state of FIG. 2, the driving of the chains 16R and 16L is stopped. Then, the parallel link robot 14 places the remaining articles W (fifth stage) on the fourth stage articles W from the article supply conveyor 12, and the bottom ten articles W after the stacking are completed. The product article extrusion device 18 and the case holding device 20 are put into the case C by a boxing process (described later) performed in cooperation.

  When the boxing process of the lower ten articles W is completed, the chains 16R and 16L are moved again by the drive motors 160 and 160, and the finger pairs 16F and 16F are lowered by the finger interval. Then, the supply of the articles W from the article supply conveyor 12 by the parallel link robot 14 is restarted, and four (6th to 9th stages) articles W are stacked on the next finger pair 16F, 16F. Each finger pair 16F, 16F is lowered by the finger interval. Then, when the last one (tenth stage) article W is placed on the next finger pair 16F, 16F, each finger pair 16F, 16F is lowered again by the desired finger interval, and the lowest The article W is placed on the guide plates 194 and 194. That is, the stacking depicted on the lower side of FIG. 2 is completed, and the same processing is repeated.

  Next, with reference to FIGS. 3, 4, and 5, a boxing process performed in cooperation with the stacked article extruding device 18 and the case holding device 20 will be described. 4 (a) to 4 (d) and FIGS. 5 (e) to 5 (g), the articles W stacked by the stacking device 16 are transferred to the case C by the stacked product extrusion device 18 and the case holding device 20. It is a figure which shows the process until it is boxed in time series.

  When the stacking of the articles W is completed, the driving pulleys 184 and 188 are simultaneously driven, and the pusher moving endless belt 180 and the guide plate moving endless belts 182 and 182 travel in the same direction and at the same speed. As a result, the guide plates 194 and 194 on which the first-stage article W is placed move toward the case C, and the first-stage article W also tries to move together. A projecting body provided on the front edge of the lower end of the pusher 192 on the first-stage article W when the first-stage article W slides on the guide plates 194 and 194 due to abrupt operation of the guide plates 194 and 194. 196 contacts and moves toward the case C (FIG. 4A). Since the second-stage article W is supported by the first finger pair 16F, 16F, the first-stage article W is disposed above the first-stage article W by a predetermined distance and moved. Stays in its original position without being affected by

  Since the abutting plate 192P of the pusher 192 is inclined so that the lower end portion protrudes in the advancing direction, when the pusher 192 further advances, the abutting plate 192P abuts against the second-stage article W, Four articles W in the 2nd to 5th stages supported by the finger pairs 16F and 16F are advanced, and then the abutment plate 192P is further supported by the second finger pair 16F and 16F. The four articles W in the sixth to ninth stages are moved forward (FIG. 4B).

  Finally, the contact plate 192P comes into contact with one article W on the 10th stage supported by the third finger pair 16F, 16F, and all 10 articles W are advanced toward the case C. The As a result, the ten articles W stacked vertically by the stacking device 16 are stacked obliquely along the contact plate 192P by the protrusions 196 and the contact plate 192P (the lower product W is It advances toward case C in a more advanced state). As a result, the second, sixth, and tenth articles W supported by the first to third finger pairs 16F and 16F from the bottom are separated from each finger 16F, and all the ten-stage articles W are Then, it is transferred in a state where it is obliquely stacked on the first article placed on the guide plates 194 and 194 (FIG. 4C).

  Thereafter, the articles W stacked obliquely are pushed into the opening of the case C while being supported by the pusher 192 together with the guide plates 194 and 194 and supported by the side guides 22 and 22 on both sides. At this time, the stacked articles W are pushed into the opening of the case C in order from the lower article W, and before the pusher 192 passes over the rotation shaft of the driven pulley 186, the stacked articles W All the leading edges are inserted into the case C (FIG. 4 (d)). At this time, since the front edges of the plurality of articles W do not simultaneously start contact with the openings, the stacked articles W can be stably and easily inserted into the case C.

  When the base portion (attachment portion to the belt 180) of the contact plate 192P passes on the rotation shaft of the driven pulley 186, the guide plate moving endless belts 182 and 182 are driven in reverse at substantially the same timing, and the guide plates 194 and 194 are driven. Is retreated. In parallel with this, the elevating device 274 starts the lowering of the elevating block 270, and the case holding portion 262 that holds the case C at the boxing start position starts lowering and rotating (FIG. 5 (e)).

  When the base portion (attachment portion to the belt 180) of the contact plate 192P passes on the rotation shaft of the driven pulley 186 and starts to move along the arc of the driven pulley 186, the base portion of the contact plate 192P and the support arm 192A. The linear distance between the base portions (attachment portions to the belt 180) gradually decreases, and the contact plate 192P is tilted forward with respect to the belt tangential direction. In parallel with this, the case C is lowered in the vertical direction while being rotated by the case rotating device 26, and the stacked articles W slide down to the back of the case C under their own weight while being aligned. At this time, the contact plate 192P that rotates around the driven pulley 186 covers the opening of the case C like a lid and prevents the article W from spilling out of the case C due to impact or the like. During this time, the guide plate 194 is retracted to the original position where the next set of articles W is placed (FIG. 5 (f)).

  Further, when the base of the support arm 192A passes over the rotation axis of the driven pulley 186, and the base of the contact plate 192P and the base of the support arm 192A start to move along the arc of the driven pulley 186, the contact plate 192P becomes a state standing upright in the radial direction, and the forward inclination with respect to the belt tangential direction stops. While the base of the contact plate 192P and the base of the support arm 192A are moving along the arc of the driven pulley 186, the contact plate 192P moves along the arc of the driven pulley 186 while maintaining the same posture. Is done. The base of the abutment plate 192P rotates about 90 ° on the outer periphery of the driven pulley 186, and the case holding portion 262 is rotated 90 ° at substantially the same timing as the abutment plate 192P is substantially horizontal, and the packaging is completed. Reach position. At this time, the case C is positioned below the pusher moving endless belt 180, the opening of the case C is directed upward, and the boxed box is packed into the case C of one set (ten pieces) of articles W. Completion is complete (FIG. 5 (g)).

  Thereafter, the case C in which boxing has been completed is immediately sent to the next step by a conveying device (not shown). On the other hand, the contact plate 192P continues to move along the arc of the driven pulley 186, and when the base of the contact plate 192P passes through the arc section of the driven pulley 186, the inclination of the contact plate 192P gradually reaches the original angle. Returned. The pusher 192 is then intermittently conveyed below the pusher moving endless belt 180 and returned to the original position above the pusher moving endless belt 180 via the driving pulley 184. During this time, the same boxing operation is repeated by the other pushers provided on the pusher moving endless belt 180.

  As described above, according to the boxing apparatus of this embodiment, stacked articles can be smoothly accommodated in a case.
