  As an example of the conventional boxing apparatus, there is an apparatus disclosed in Japanese Patent Laid-Open No. 9-77003. This apparatus is for storing products such as a bag-packed product 1 and a box-packed product (not shown) as shown in FIG. In FIG. 17A, the bag-packed products 1 conveyed by the introduction conveyor 4 are one by one with respect to the gap portion 6 formed by a large number of fins 5 provided on the transfer surface of the alignment conveyor 3. It is inserted and aligned in a row while standing on the transfer surface of the alignment conveyor 3.

  Next, as shown in FIG. 17A, when a predetermined number of, for example, five bag-packed products 1 are aligned on the alignment conveyor 3, the extrusion provided with slits 12 for avoiding interference with the fins 5 is provided. The plate 11 pushes out the five packed products 1 on the aligning conveyor 3, and supplies them to the damper plates 7 and 7 that can be freely opened and closed via the U-shaped intermediate body 10 (FIG. 17). (See (b)). On the damper plates 7 and 7, five bag-packed items 1 are extruded twice.

In addition, the extrusion plate 11 is aligned so as not to interfere with the next bagging product 1 being aligned on the alignment conveyor 3 when the bagging products 1 are pushed out to the predetermined positions on the damper plates 7 and 7 by five. The upper part of the conveyor 3 is slid in the direction opposite to the pushing direction and returned, and waits at the position shown in FIG. 17A until the next pushing operation starts.
Next, as shown in FIG. 17 (b), the packaged product 1 pushed out in a standing state on the damper plates 7, 7 is sandwiched and held by the pair of holding plates 9, 9 from the front and rear.
Next, as shown in FIG. 18 (a), the damper plates 7, 7 are changed from the closed state to the open state, the cardboard case (exterior box) 2 waiting in the lower position is raised, and the holding plate 9, 9 is inserted into the cardboard case 2. The cardboard case 2 is conveyed by a roller conveyor (not shown) and is waiting at a predetermined standby position. Reference numeral 2 a shown in FIG. 18A denotes a flap of the cardboard case 2.

Then, the push-in plate 13 is lowered, and the pair of holding plates 9 and 9 are driven in a direction in which the push-in plate 13 spreads to release the pressing force on the bag-packed product 1. In this way, the bag-packed product 1 is stored in the cardboard case 2 (see FIG. 18A).
Next, as shown in FIG. 18B, the corrugated cardboard case 2 in which the bagging product 1 is accommodated is lowered to drive the damper plates 7 and 7 from the open state to the closed state. In this way, the original state shown in FIG. 17A is restored, and one cycle of the storing operation of the bag-packed product 1 is completed. Thereafter, the above-mentioned cycle is automatically repeated to perform the packing operation.

  For example, in the case where a thick bag-packed product 1 is boxed in the cardboard case 2, the distance between the fins 5 and 5 may be widened, but in order to widen the distance between the fins 5 and 5, each fin 5 is conveyed. It is necessary to remove each screw attached to the surface, and there is a problem that it takes a lot of labor and time.

  An object of this invention is to provide the conveying apparatus which can remove | desorb a fin easily.

  In FIG. 9, reference numeral 58 denotes an aligning conveyor. The introducing conveyor 4 is connected to the aligning conveyor 58, and the bagging product 1 is transferred to the aligning conveyor 58 by the introducing conveyor (feeding means) 4. That is, the bag-packed product 1 conveyed by the introduction conveyor 4 is formed by a large number of fins (this fin is a partitioning means described in the claims) 5 provided on the transfer surface of the alignment conveyor 58. One by one is sequentially supplied to each of the gap portions 6 and is loaded at right angles to the transfer surface of the alignment conveyor 58, that is, in an upright state. Incidentally, the alignment conveyor 58 is driven and controlled to perform an intermittent motion by the two first and second stepping motors 8a and 8b and its control device, and the intermittent motion is shown in FIG. 9 (a). As described above, one bag-packed product 1 conveyed by the introduction conveyor 4 is set to be loaded in one gap portion 6.

Next, as shown in FIG. 9B, for example, when a predetermined number of five bag-packed products 1 are loaded and aligned in the five gap portions 6 between the fins 5 of the alignment conveyor 58, The extrusion plate 11 provided with the slits 12 for avoiding interference (extraction means according to claim 5) extrudes the five packed products 1 aligned on the alignment conveyor 58, and FIG. Is supplied onto damper plates 7 and 7 that can be opened and closed, which will be described later, via a U-shaped intermediate body 10 (see FIG. 9C). That is, the push plate 11 can be slid on the alignment conveyor 58 in the horizontal direction perpendicular to the alignment conveyor 58 by a linear motion mechanism 55 to be described later. Can be pushed through the intermediate body 10 onto the damper plate 7 in the holding position. Reference numeral 34 shown in FIG. 9C denotes a stopper plate for aligning and stopping the packed products 1 pushed out onto the damper plate 7 in one row.
The slide operation for the push-out plate 11 to push out the bag 1 is controlled so as to be performed when the alignment conveyor 58 is temporarily stopped at a predetermined position by an intermittent motion. Incidentally, the operation of the extrusion plate 11 is not limited to the above, and the operation stroke or the like can be freely adjusted according to the width of the bag-packed product 1 or the number of rows stored in the outer box 2. I can do it.

As described above, when the extrusion plate 11 extrudes the bag-packed product 1 to a predetermined position on the damper plate 7, the extrusion plate 11 slides horizontally in the direction opposite to the extrusion direction, and the bags of the alignment conveyor 58. The stuffed product 1 is temporarily stopped in front of the six fins 5 that have been emptied (FIG. 10 (a)), and thereafter, the slidable product 1 is further slid in the horizontal direction so as not to interfere with the fins 5. Is returned to the origin position and waits until the next push-out operation is started (FIG. 10B).
At this time, as shown in FIG. 10 (b), the pushing plate 13 descends to a predetermined height and presses the upper edges of the five bag-packed products 1 on the damper plate 7 to raise the height of each bag-packed product 1. Align.

  Next, as shown in FIGS. 10 (b) and 10 (c), the side plate 35 in the horizontal position rotates to the vertical position, and the alignment conveyor 58 for the five packaged products 1 on the damper plates 7, 7. Each side edge of the side is pressed and the width direction of each bag-packed product 1 is aligned. Further, the five pieces of one row of bag-packed products 1 on the damper plate 7 are sandwiched from both the left and right sides by holding plates 9 and 9 provided perpendicularly to the both side positions in the alignment direction of the bag-packed products 1, and this holding is performed. The pressing force of the plates 9, 9 and the stopper plate 34 and the side plate 35 are held by the pressing force pressing the bag-packed product 1 from both the left and right edges (holding state).

  As described above, when the bag 1 is held by the holding plates 9, 9, the stopper plate 34 and the side plate 35, as shown in FIG. The damper plates 7 and 7 are driven from the closed state (the holding position) to the open state (the non-holding position). Then, the outer box 2 waiting on the outer box lifting platform 17 shown in FIG. 4 is lifted by the outer box lifting mechanism 98 and moved to a position below the bag-packed product 1. The exterior box 2 is conveyed by the carry-in conveyor 96 shown in FIG. 4 and is waiting at a predetermined position on the lifting platform 17. 11 is a flap for the outer packaging box 2, and 36 is a guide for guiding the bagging product 1 when the bagging product 1 is pushed into the outer packaging box 2.

  Next, as shown in FIG. 11 (b), the holding plates 9, 9 are slightly moved in the expanding direction by the expansion / contraction devices 16, 16 (see FIG. 3) to release the force for pinching the bag-packed product 1 ( In the non-holding state), the pushing plate 13 is lowered and the five bag-packed items 1 can be forcibly pushed into the bottom of the outer box 2 and stored. Then, as shown in FIG. 11 (c), the side plate 35 in the vertical position is rotated back to the original horizontal position, and the damper plate 7 in the open state by driving the opening / closing device as shown in FIG. , 7 are moved to the closed state.

  Thereafter, the outer box 2 in which the bag-packed product 1 is stored is lowered to the original lowered position and discharged to a predetermined discharge position, and the next outer box 2 is supplied to a position below the damper plates 7 and 7. At the same time, the push-in plate 13 returns to the original raised position, and the holding plates 9, 9 return to the original open state. This completes one cycle of the boxing operation for the bag-packed product 1. Thereafter, the boxing operation can be automatically repeated by sequentially repeating the above steps.

Next, the introduction conveyor 4, the alignment conveyor 58, the extrusion plate 11 and its operation mechanism will be described in order.
[Introduction conveyor 4 and alignment conveyor 58]
The introduction conveyor 4 shown in FIG. 9 is a belt conveyor made of synthetic rubber, and sequentially conveys the packed products 1 supplied at a substantially constant interval from a vertical pillow packaging machine or the like provided at the preceding stage. It is supplied to the alignment conveyor 58 provided in the subsequent stage. However, there may be a variation in the interval between the bag-packed products 1 depending on the operation state of the packaging machine in the previous process. Therefore, as shown in FIG. 1, an article sensor 20 for detecting the bag-packed product 1 is provided at the entrance of the alignment conveyor 58, and is provided on the alignment conveyor 58 based on the detection signal of the article sensor 20. The first and second driving stepping motors 8a and 8b are activated at an appropriate timing.

  As shown in the plan view of FIG. 2, the aligning conveyor (conveying device according to claim 1) 58 includes four annular chains 18a, 18b, 21c, and 21d, and the chains 18a and 18b are the first series. The chains 21c and 21d belong to the second group. The chains 18a and 18b belonging to the first series travel while being driven by the first stepping motor 8a, and the chains 21c and 21d belonging to the second series travel while being driven by the second stepping motor 8b. The first series of chains 18a and 18b are provided with mounting brackets 33 for holding the fins 5 at positions facing each other, and two pairs of mounting brackets 33 provided on the chains 18a and 18b are used. One fin 5 can be detachably attached.

As shown in FIGS. 1 and 2, the first group of chains 18 a and 18 b has a total of 21 pairs of first group fittings 33 to which a maximum of 21 fins 5 can be attached. And a total of 21 pairs of mounting brackets 33 of a second group that can be attached to a maximum of 21 fins 5 at a location that is delayed by a half cycle of the travel route. Further, the same number of mounting brackets 33 of the first and second groups equivalent to the first chain 18a and 18b are provided in the second chain 21c and 21d.
Therefore, as shown in FIG. 1, the alignment conveyor 58 includes a first group (a group) of fins 5 and a second group (a group) belonging to the first series driven by the first stepping motor 8 a. A first group of fins 5, and a first group (a group of) fins 5 and a second group (a group of) fins 5 belonging to the second series driven by the second stepping motor 8 b. ing.

  Note that first drive sprockets 22 a and 22 b that are coupled to the first drive shaft 24 and rotate with the first drive shaft 24 are arranged at the left end (entrance) of the alignment conveyor 58 shown in FIG. 1. And second driven sprockets 22c and 22d supported so as to be rotatable with respect to the first drive shaft 24, and the second end (exit) of the alignment conveyor 58 has a second driven sprocket 22c and 22d. Second drive sprockets 25c and 25d that are coupled to the drive shaft 26 and rotate along with the second drive shaft 26, and a first that is rotatably supported with respect to the second drive shaft 26. Driven sprockets 25a and 25b are provided. The first chain 18a and 18b are hung on the first driving sprockets 22a and 22b and the first driven sprockets 25a and 25b, respectively. The second drive sprockets 25c and 25d and the second driven sprockets 22c and 22d are respectively hung by the second chain 21c and 21d. The first and second drive shafts 24 and 26 are connected to corresponding rotary shafts of the first and second stepping motors 8a and 8b via timing belts.

As shown in FIG. 1, the fin 5 is an L-shaped metal plate, and a gap portion 6 is formed in a gap defined by adjacent fins 5. The gap portion 6 is formed slightly wider than the thickness of the bag-packed product 1. That is, the bag-packed product 1 can be held in a slightly loose state in the upright state. Further, the fins 5 spread radially at the entrance of the aligning conveyor 58 to form the input port 23 for the bag-filled product 1 so that the bag-filled product 1 conveyed by the introduction conveyor 4 slides into the input port 23. It is configured. Each traveling position of the fin 5 forming the insertion port 23 is a receiving position 43.
In addition, the bag goods 1 conveyed by the introductory conveyor 4 are conveyed with the bottom part forward, and therefore the bag goods 1 supplied one by one to the gap part 6 are in an upright state with the bottom part downward. Align. The alignment conveyor 58 shown in FIGS. 1 and 2 is the alignment conveyor 58 shown in FIGS. 9 and 10. The number of fins 5 constituting each group is six, and the number of fins 1 to be pushed out by the extrusion plate 11 at one time is exactly the number of pieces to be held.

Next, an electric circuit of the boxing device will be described with reference to a block diagram shown in FIG. The boxing device includes a controller (CPU as a control means) 27. The controller 27 performs various arithmetic processes according to a program stored in advance in the storage unit 28, and performs first and second stepping motors 8a and 8b. And each drive part, such as the stepping motor 41 for operating the extrusion plate 11, is driven.
The setting display unit 30 connected to the controller 27 sets, for example, the traveling speed when the first and second fins 5 receive the supply of the bagging product 1 from the introduction conveyor 3 (FIG. 9). Traveling speed when moving the fins 5 of the group in which receiving or taking out of the individual bag-packed products 1 (FIGS. 9B and 9C) is finished to the take-out position 19 or the receiving position 43 in the next process Further, the operation timing of each process can be set.

  In addition, the traveling speed when moving the fins 5 of the group that has finished receiving or taking out the bag-packed product 1 to the take-out position 19 or the receiving position 43 in the next process is such that the fins 5 of each group move from the introduction conveyor 3 to the bag. The speed is set to be higher than the traveling speed when receiving the supply of the stuffing 1, and the controller 27 can cause the fins 5 of each group to travel between the two processes at the set high traveling speed. . Note that the traveling speed of the fins 5 when receiving the supply of the bag-packed product 1 from the introduction conveyor 3 refers to the average speed of the fins 5 that travel intermittently. However, when it is set as the alignment conveyor of the type where the fin 5 travels at a constant speed, the traveling speed is said.

  Then, according to the program stored in the storage unit 28, the controller 27 assigns one of the first group of fins 5 and the second group of fins 5 to the group of fins 5. As shown in FIG. 9 (a), the group of fins 5 is moved by the extruding plate 11 as shown in FIG. 9 (b). Means are provided that can stop or slow down at the take-out position 19 from which the stuffed product 1 is taken out and can stand by.

In addition, the controller 27 accepts the position of either one of the first group of fins 5 and the second group of fins 5 according to the program stored in the storage unit 28. Means for allowing the other group of fins 5 to finish taking out the packaged product 1 and waiting in front of the receiving position 43 in a state where the packaged product 1 is received at 43, and the group of one fin 5 In the state where the bag 1 is received at the receiving position 43, the other group of fins 5 finishes receiving the predetermined number of preset bags, for example, five bags 1, and before the take-out position 19. Means capable of waiting are provided.
In order to realize this, as shown in FIG. 1, after the bag 1 is taken out from the group of the first fins 5 of the first series, the second of the first series is taken out. The length of the alignment conveyor 58 is determined so that the group of fins 5 can stand by in front of the group of the first fins 5 in the second series, as indicated by a two-dot chain line. Further, this alignment conveyor 58 is arranged so that the group of the first fins 5 of the second series that has finished receiving the five bag-packed products 1 can wait at a predetermined position indicated by a two-dot chain line before the take-out position 19. The length of is defined. However, in FIGS. 9 and 10, the alignment conveyor 58 is schematically illustrated in a short form, but is the same as FIG. 1.

Further, the controller 27 includes a take-out position sensor 31, an article sensor 20, an origin position sensor 42, pulse transmitters 32a, 32b, 38, drivers 39a, 39b, 40, stepping motors 8a, 8b, 41, a storage unit 28, and Although not shown in detail, various drive units and sensors such as the expansion / contraction device 16 provided in the boxing device are connected.
When the group of fins 5 supplied with a predetermined number of, for example, five bag-packed products 1 is conveyed in the direction of the pick-up position 19 from which the bag-packed products 1 are picked up, the take-out position sensor 31 Is detected and stopped at the take-out position 19 (position where the first group of first fins 5 is stopped) shown in FIG.
As shown in FIG. 1, the article sensor 20 detects the packaged product 1 when one packaged product 1 conveyed by the introduction conveyor 4 is loaded into one gap portion 6, and this detection signal is used. This is for driving the fin 5 to move the next gap portion 6 to the loading position of the bagged product 1.
As shown in FIG. 9B, the origin position sensor 42 is for detecting the extrusion plate 11 when the extrusion plate 11 is at the origin position. When the pushing plate 11 at the origin position is detected, the bag-filled product 1 held by the group of fins 5 at the taking-out position 19 can be pushed out and taken out.

  Each pulse transmitter 32a, 32b, 38 transmits the number of pulses designated by the controller 27, and each driver 39a, 39b, 40 corresponds to each rotation angle corresponding to the transmitted pulse. The stepping motors 8a, 8b and 41 are rotationally driven.

  The operation of the alignment conveyor 58 of the bagging apparatus configured as described above will be described with reference to the flowchart shown in FIG. When one of the first group of fins 5 and the second group of fins 5 moves to the receiving position 43 of the bag 1, each of the fins 5. The controller 27 determines whether or not the bag 1 is inserted into the gap 6 (S100), and when the bag 1 is inserted into the gap 6 and it is determined YES, the fin 5 is sent by one pitch. The stepping motor corresponding to is driven (S102). Then, the controller 27 determines whether or not a predetermined number of, for example, five bags 1 are supplied to the five gap portions 6 of the six fins 5 of this group (S104). When it is determined NO because the five bags 1 are not supplied, the processes of steps S100 to S104 are repeated. In step S104, when five bag-filled products 1 are supplied and it is determined YES, the fin 5 is moved from the receiving position 43 to the next process at a higher speed than the speed at which the fin 5 passes through the receiving position 43. Move to the take-out position 19 (S106). When the group of the fins 5 moves to the take-out position 19, the five bag-filled products 1 held in the gap portions 6 of the fins 5 are pushed out by the push-out plate 11 and taken out. The vehicle is stopped at a plurality of predetermined positions (S108), and thereafter, the vehicle is caused to travel from the predetermined position to the receiving position 43 of the next process at a speed higher than the speed when passing through the receiving position 43. However, each group of fins 5 is controlled to run so as not to interfere (contact) with other groups of fins 5 in front.

  Thus, since the moving speed of the fins 5 of each group between the receiving position 43 and the taking-out position 19 is higher than the speed when passing through the receiving position 43, the moving time can be shortened. It is possible to shorten one cycle time required for supplying and taking out the bag-packed product 1 from the alignment conveyor 58. As a result, the processing capacity of the boxing device can be improved.

  And since the fin 5 of the 1st and 2nd series can be made to run independently, respectively, in order for the group of one fin 5 of the 1st and 2nd fins 5 to receive bagging goods 1 While being intermittently driven and traveling in the receiving position 43 at a predetermined receiving speed, the bag-packed product 1 can be taken out from the group of the other fins 5 stopped at the taking-out position 19, for example. The receiving speed refers to the average traveling speed of the fins 5 that are intermittently driven.

  Therefore, waiting for the removal or acceptance of the bag 1 to the other group of fins 5 until the processing is completed in a state where the group of one fin 5 has received or removed the bag 1. Therefore, it is possible to shorten one cycle time for supplying and taking out the bag-packed product 1 from the alignment conveyor 58.

In addition, as shown by a two-dot chain line in FIG. 1, in a state where one of the groups of fins 5 of the first and second groups receives the bag 1 at the receiving position 43. The other group of fins 5 can finish taking out the bag 1 and wait in front of the receiving position 43, and the one group of fins 5 can receive the bag 1 at the receiving position 43. In this state, the other group of fins 5 can complete the acceptance of the bag 1 and wait in front of the take-out position 19.
Therefore, it is possible to sequentially take out and receive the bag-packed product 1 and thereby improve the processing capacity of the boxing device to which the alignment conveyor 58 is applied.

Next, the attachment mechanism 44 of the fin 5 will be described with reference to FIG. 2 and FIGS.

Screwed to the lower ends of each of these by nuts 51. The retaining portion 46 has an outer diameter smaller than the inner diameter of the wide portion 47 of the insertion hole 45 and wider than the narrow portion 48, and is inserted through the wide portion 47 and moved to the narrow portion 48 side. Thus, it is possible to contact the lower surface of the edge 48a of the narrow portion 48.

Each extending portion 50 is inserted through an inner hole of a short cylindrical holding member 52 as shown in FIG.
The pressing member 52 is movable in the length direction with respect to the extending portion 50, and has a large-diameter bowl-shaped portion 52a at the lower end portion. A coil spring 53 is mounted on the outer periphery of the holding member 52, and the lower end of the coil spring 53 comes into contact with the hook-like portion 52a to press the holding member 52 against the retaining portion 46 by a spring force. (State shown in FIG. 6A). FIG. 6B shows a state in which the holding member 52 is slid upward against the spring force of the coil spring 53.

Projected. As shown in FIG. 8, the locking portion 54 engages with a retaining portion 46 that is pressed against the lower surface of the edge portion 48 a of the narrow portion 48 by a spring 53, so that the retaining portion 46 faces the wide portion 47 side. The fins 5 are locked so as not to move so that the fins 5 are not detached from the pair of mounting brackets 33, 33. Further, the extending portion 50 is in contact with the inner edge 48a of the narrowed portion 48 in a state where the locking portion 54 and the retaining portion 46 are engaged, whereby the locking portion 54 is attached to the pair of fins 5. It also functions to position the brackets 33, 33.

According to the attachment mechanism 44 configured as described above, each fin 5 can be detachably attached to the pair of attachment fittings 33, 33 of each group. When the fin 5 is attached to a pair of mounting brackets 33, 33 of any group, the fin 5 is directed in a predetermined direction shown in FIG. 1, and as shown in FIGS. 7 (a) and 7 (b). The pair of retaining portions 46 provided in the pair are inserted into the wide portions 47 of the respective insertion holes 45 provided in the pair of mounting brackets 33 and 33 from the upper side against the force of the spring 53 and pushed. At this time, since the lower surface of the flange-shaped portion 52 a of the pressing member 52 contacts the upper surface of the edge portion of the wide portion 47, the fin 5 is biased upward by the force of the pair of springs 53. Then, as shown in FIGS. 7C and 7D, the pair of retaining portions 46 are moved into the narrowed portion 48 side while being pushed into the wide portions 47, and the pair of extending portions 50 are The fin 5 is moved to the right to a position where the edge 48a at the right end of the narrow portion 48 contacts. At this time, the locking portion 54 is moved over the retaining portion 46 on the right side of FIG. Next, the force by which the operator pushes the fin 5 downward is loosened, and each retaining portion 46 is pressed against the lower surface of the edge portion 48a of each narrow portion 48 by the force of the pair of springs 53 as shown in FIG. What should I do? In a state where the retaining portion 46 is pressed against the lower surface of the edge portion 48a of the narrow portion 48, the movement of the retaining portion 46 toward the wide portion 47 side is retained by the retaining portion 54, so that the fin 5 is attached to the mounting bracket. 33, 33 can be prevented from coming off.
When removing the fin 5 from the pair of mounting brackets 33, 33, a procedure reverse to the above-described mounting procedure may be performed. That is, the fin 5 is pushed downward against the force of the pair of springs 53 to pull the retaining portion 46 away from the lower surface of the edge portion 48a of the narrowed portion 48, and the retaining portion 54 is engaged with the retaining portion 46 in this separated state. Is moved to the wide portion 47 side, and the retaining portion 46 is removed from the wide portion 47.

  This boxing device is configured to hold the bagging product 1 in each gap portion 6 between the fins 5..., And accordingly, when the thickness of the bagging product 1 is changed, the thickness of the bagging product 1 is changed. It is necessary to change the mounting positions of the plurality of fins 5 so that the corresponding intervals are obtained. Therefore, according to the attachment mechanism 44, no tool is required when attaching and detaching the fins 5 to and from the attachment fittings 33 and 33 (chains), and they can be easily attached and detached. The fins 5 can be positioned at a predetermined mounting position by the locking portions 54 and can be prevented from being removed during operation. Further, when the number of fins 5 to be attached is changed in accordance with the change in the number of bags 1 to be packaged in the outer box 2, the fins 5 can be easily attached or detached.

[Extruded plate 11 and its operating mechanism]
The extrusion plate 11 is made of a metal plate, as shown in FIGS. 3 to 5 and FIG. 9B, etc., and the pressing portion for pushing out the bag-packed product 1 includes the fins 5 provided on the alignment conveyor 58. A slit 12 having a width that can avoid interference is provided. Therefore, the extrusion plate 11 is prepared in accordance with the number of fins 5 attached to each group and the distance between the gap portions 6 of the fins 5. The push plate 11 is operated by a horizontal linear motion mechanism 55.
As shown in the side view of FIG. 5, the linear motion mechanism 55 has a reciprocating table 56, and the movement path of the reciprocating table 56 is orthogonal to the conveying direction 57 of the alignment conveyor 58. The main body frame 37 is provided in a direction (horizontal direction) parallel to the transport surface. The linear motion mechanism 55 is configured such that the reciprocating table 56 reciprocates within the range of the stroke S1 shown in FIGS.
When the pushing plate 11 provided on the reciprocating table 56 of the linear motion mechanism 55 advances from the origin position shown in FIG. 5 by the stroke S1, the five packed products 1 aligned on the aligning conveyor 58 are held by the holding plates 9 and 9. Can be moved between.

The linear motion mechanism 55 is of a timing belt type, for example, although not shown in the drawing. A reciprocating table 56 is coupled to the timing belt, and the reciprocating table 56 is guided by a rail (not shown) and can reciprocate freely. The timing belt is hung on the driven side timing pulley and the driving side timing pulley provided on the rotating shaft of the stepping motor 41. The stepping motor 41, the rail, the driven side timing pulley, and the drive side timing pulley are provided on the main body frame 37 side.
However, although the linear motion mechanism 55 is a timing belt type, the drive plate 11 provided on the reciprocating table 56 may be reciprocated using another drive type.

The stepping motor 41 is automatically controlled and driven by a controller (CPU) 27, and the controller 27 performs processing according to a predetermined program having the contents shown in the flowchart of FIG.
The extrusion plate 11 is driven and controlled by the controller 27 and is aligned when one of the four groups of fins 5 is stopped at the take-out position 19 of the bag 1 shown in FIG. 9B. 5 bags are held in the gaps 6 between the fins 5 by moving along a predetermined horizontal movement path across the alignment conveyor 58 from the origin position shown on the side of the conveyor 58. The product 1 can be extruded and the five bag products 1 can be transferred between the holding plates 9 and 9. And it is the structure which can move the predetermined movement path | route to the direction opposite to the above, and can return to an origin position at the timing which does not interfere with the group of fin 5 by which the bagging goods 1 were extruded.

  Next, the operation of the linear motion mechanism 55 will be described with reference to the flowchart shown in FIG. Now, it is assumed that the extrusion plate 11 is at the origin position shown in FIG. An extraction position sensor 31 indicates that five bags 1 are supplied to one group of fins 5 of the alignment conveyor 58 and that the group of fins 5 is stopped at the extraction position 19 shown in FIG. Is detected (S200), the stepping motor 41 of the linear motion mechanism 55 is driven to slide the extrusion plate 11 from the origin position, so that the packaged product 1 is held between the holding plates 9 and 9 as shown in FIG. Transfer between them (S202). Then, as shown in FIG. 10A, the linear motion mechanism 55 is driven backward to stop the pushing plate 11 just before the alignment conveyor 58 (S204, S206). Then, it is determined whether or not the group of fins 5 from which the bag 1 has been taken out has moved to a predetermined position and stopped (S208), and the group of fins 5 has stopped at the predetermined position and YES. When it is determined, the linear motion mechanism 55 is driven backward to return the pushing plate 11 to the origin position (S210).

  The predetermined position of the group of fins 5 at which the extrusion plate 11 can return to the origin position is a position at which the fins 5 can pass through the slits 12 of the extrusion plate 11 when the extrusion plate 11 crosses the alignment conveyor 58. . In this embodiment, the group of fins 5 from which five bag-packed items 1 have been taken out travels intermittently by one pitch of the fins 5 from the take-out position, and when the fins 5 are stopped, FIG. As shown in a) and (b), the extrusion plate 11 stopped in front of the alignment conveyor 58 returns to the origin position. Thus, each position where the fin 5 stops when performing intermittent travel is the predetermined position. After the extrusion plate 11 returns to the origin position, the group of fins 5 is moved to the receiving position 43 by traveling at the predetermined high speed. Of course, the traveling speed is controlled so as not to interfere with other groups of the front fins 5 and so that the bag-packed product 1 can be received from the introduction conveyor 4. In this way, the extrusion plate 11 can take out the bag 1 that is held in one group of fins 5 and can take out the bag 1 that is held in the next group of fins 5. The bag-packed products 1 can be sequentially taken out from the alignment conveyor 58 by repeating the same procedure as described above.

  However, the group of the fins 5 from which the bag-packed product 1 is taken out travels intermittently from the take-out position 19 by one pitch of the fins 5 and each stop position until the pushing plate 11 returns to the origin position is set as a predetermined position. However, instead of this, the group of fins 5 may be configured to intermittently travel from the take-out position 19 by a predetermined pitch of two or more pitches of the fin 5. FIG. 13 shows a case where the pushing plate 11 returns to the origin position before the group of fins 5 moves from the take-out position to the first predetermined position.

According to the horizontal linear motion mechanism 55 of the extrusion plate 11 configured as described above, the extrusion plate 11 reciprocates along a predetermined horizontal movement path across the alignment conveyor 58 to form a group of fins 5. Since the held bagging product 1 is taken out, the height of the boxing device is lowered by the height of the raising and lowering as compared with the conventional boxing device shown in FIG. The bulk can be reduced.
Then, as shown in FIG. 10A, when the bag-packed product 1 is pushed out and returned to the origin position, it stops before the alignment conveyor 58, and the group of fins 5 is one of a plurality of predetermined positions. The extrusion plate 11 is returned to the origin position when it is determined that it has stopped at the predetermined position, and thus the waiting time until the extrusion plate 11 returns to the origin position can be shortened. The group of the fins 5 taken out can be moved in a direction in which the group of the fins 5 approaches the receiving position 43 of the bag-packed product 1. As a result, the processing capacity of the boxing device can be improved.

  However, in the above-described embodiment, five bag-packed products 1 are arranged in one row, but may be a predetermined plurality other than five. And although the bagging goods 1 were stored in the exterior box 2 in 1 row, it can be set as 2 or more predetermined rows. Moreover, although five rows are arranged in one row and packed in one row, a plurality of rows can be formed. When the number of rows, the number of rows, and the number of rows of the bag-packed product 1 are changed in this way, the shape of the extrusion plate 11, the interval between the holding plates 9, the lifting stroke of the pushing plate 13, and the operation timing thereof Etc. will be changed as necessary.

  Moreover, in the said embodiment, as shown in FIG. 9, the bagging goods 1 are supplied to the alignment conveyor 58 from the introduction conveyor 4 one by one, and the bagging goods 1 are arranged on the alignment conveyor 58 in five lines. Although not shown in the figure, the bags 1 are supplied to the alignment conveyor 58 from the introduction conveyor 4 in a state where, for example, two or more predetermined numbers are arranged in a horizontal row, 1 may be inserted into the gap 6 between the fins 5 by a predetermined number of two or more, and may be arranged in two or more predetermined rows. In this case, the shape of the extrusion plate 11, the interval between the holding plates 9 and 9, the operation timing thereof, and the like are changed as necessary.

  Further, in the above embodiment, as shown in FIG. 9, the bag-filled products 1 on the introduction conveyor 4 are laid sideways so that the bottom faces forward, so that they are aligned in an upright state on the alignment conveyor 58. In the state where the bagging product 1 on the introduction conveyor 4 is laid sideways and the side edge (long side edge) is directed forward, the side edge is set to the lower position on the alignment conveyor 58. You may make it align. The bag-packed product 1 is aligned and boxed in this way when, for example, the other side edge on the long side of the bag-packed product 1 is the upper portion of the bag-packed product 1.

And in the said embodiment, as shown in FIG. 1, although it was set as the structure which can attach the 1st and 2nd 2 groups of the fin 5 to each of the 1st and 2nd series, it replaces with this. Thus, a configuration may be adopted in which one group of fins 5 can be attached to each of the first and second series.
Further, in the above-described embodiment, the controller 27 performs one of the fins 5 of the first group of fins 5 and the second group of fins 5 according to the program stored in the storage unit 28. The group of the other fins 5 is set in a predetermined number, for example, five bag-packed items 1 in a state of stopping (or slowing down) and waiting at the pick-up position 19 for taking out the bag-packed items 1. It is good also as a structure provided with a means which can be made to wait in front of the taking-out position 19 after completing acceptance of this. With this configuration, one group of fins 5 waits at the take-out position 19 for taking out the bag-filled product 1, and the other group of fins 5 finishes receiving the bag-filled product 1 and It is possible to wait in front, and as a result, the processing capacity of the boxing device can be improved.
