(Attaching / detaching guide member connecting parts)
FIG. 5A is a perspective view of the state when the guide member connecting part 59 is removed as viewed from above, and FIG. 5B shows the state when the guide member connecting part 59 is removed downward. It is the perspective view seen from. Here, FIG. 5B is a diagram viewed from the arrow c side in FIG. Here, a method of attaching / detaching the guide member connecting component 59 on the one rotating shaft 53a side will be described, but the method of attaching / detaching the guide member connecting component 59 on the other rotating shaft 53b side is also the same.

  The attachment member 57 fixed to the rotating shaft 53a is provided with substantially L-shaped attachment grooves 57a at both end portions thereof. On the other hand, the mounting groove 57a of the mounting member 57 is formed on the back surface (the surface opposite to the surface on which the guide members 41 and 42 are mounted) of both ends in the longitudinal direction of the connecting member 58 of the guide member connecting component 59. A screw part 58a to be inserted into is provided.

  When the guide member connecting component 59 is attached to the attachment member 57, the two screw portions 58a are inserted from the entrance / exit 57b of the two attachment grooves 57a and moved along the substantially L-shaped shape of the attachment groove 57a. Align with the mounting position 57c behind the lever. The guide member connecting component 59 can be attached to the attachment member 57 by inserting a flat washer and a spring washer into each screw portion 58 a and screwing a nut. The guide member connecting component 59 can be removed from the attachment member 57 by the reverse procedure.

  When the guide member connecting component 59 is attached to the rotating shaft 53a (53b) via the mounting member 57, the connecting member 58 is long in the axial direction of the rotating shaft 53a (53b), and is located on both sides in the longitudinal direction. Guide members 41, 42 (43, 44) are mounted between two screw portions 58a provided at the end.

  Further, in this example, the guide members 41 and 42 are configured so that fine adjustment of the mounting position on the connecting member 58 is possible. That is, as shown in FIG. 5B, the connecting member 58 is provided with a long hole 58b at the mounting position of the guide members 41 and 42. Then, two screw portions 405 that can be inserted into the elongated holes 58b are projected from the back side of the guide members 41 and 42. The two screw portions 405 are inserted into the long holes 58b, and flat screw washers and spring washers (not shown) are inserted into the screw portions 405, and the nuts are screwed together, whereby the guide members 41 and 42 are connected to each other. 58 is fixed. Here, when the nut (not shown) is loosened, the two screw portions 405 can be slid in the longitudinal direction of the long hole 58b, and the mounting positions of the guide members 41 and 42 can be finely adjusted. Similarly, the guide members 43 and 44 are also configured so that fine adjustment of the mounting position on the connecting member 58 is possible.

  The four guide members 41 to 44 are arranged so as to correspond to the four corners of the outer box 110 arranged at the boxing position P in plan view.

  Each of the guide members 41 to 44 is formed by bending a thin metal plate processed into a predetermined shape. The two guide members 41 and 42 attached to one rotation shaft 53a have a bilaterally symmetric structure, and each of the guide members 41 and 42 has a main piece 401 having a surface facing the opposing guide members 43 and 44, and A side piece 402 extending in the direction of the guide members 43 and 44 from the edge of the main piece 401 on the side farther from the two guide members 41 and 42 is provided. A boundary portion between the main piece portion 401 and the side piece portion 402 is a bent portion 403, and the guide members 41 and 42 having a horizontal cross-sectional shape of L shape (substantially L shape in this example) are configured.

  Furthermore, in this example, the main piece 401 of each of the guide members 41 and 42 is a main main piece 401a, and a sub main piece 401b inclined slightly inward between the main main piece 401a and the side piece 402. It consists of and. Here, although the sub main piece 401b is formed in a planar shape, it may be formed in a curved surface bulging outward. Alternatively, the main main piece 401a and the side piece 402 may be configured as the guide members 41 and 42 having an L-shaped horizontal cross section without the sub main piece 401b.

  The two guide members 43 and 44 attached to the other rotation shaft 53b have the same configuration as the two guide members 41 and 42 attached to the one rotation shaft 53a. Each of the bent portions 403 of the four guide members 41 to 44 is positioned at the apex of a square (rectangle or square) in plan view when the guide members 41 to 44 are in the hanging posture.

[Configuration of control system]
FIG. 6 is a block diagram illustrating an example of a schematic configuration of a control system of the boxing device 100.

  The control device 30 provided in the boxing device 100 includes, for example, a control unit 31 having a computing unit such as a CPU and a storage unit 32 having a memory such as a ROM and a RAM. The article detection signal output from the article take-in detection device 69 and the box detection signal output from the box detection device 25 are input to the control unit 31. Predetermined control programs are stored in the storage unit 32, and the control unit 31 reads and executes these control programs, whereby the control device 30 causes the alignment conveyor 6, the extrusion device 7, the pressing device 8, and the push-in device. The drive devices of the device 9, the floor opening and closing device 10, the pressing device 18, the outer box placement device 20 and the guide device 40 are controlled. That is, the operation of the entire boxing device 100 is controlled by the control device 30. The control device 30 may be configured by a single control device that performs centralized control, or may be configured by a plurality of control devices that perform distributed control in cooperation with each other.

[Operation of boxing device]
FIG. 7 is a flowchart illustrating an example of the operation of the boxing device 100. This operation is realized by processing of the control device 30.

  First, in step S <b> 1, the control device 30 controls the alignment conveyor 6 to align a predetermined number of articles W sequentially supplied from the supply conveyor 200 at the alignment position T.

  Next, in step S <b> 2, the control device 30 controls the pushing device 7 to move the pushing member 70 from the retracted position to the advanced position, thereby pushing the articles W aligned at the aligning position T onto the floor plate 11. . Then, the control device 30 returns the pushing member 70 from the advanced position to the retracted position. As a result, the article group is placed in the article placement position A in an aligned state.

  Next, in step S3, the control device 30 controls the pressing device 18, swings the pressing member 19 downward to the pressing position, and presses the upper side surface of the extruded group of articles. Thereby, each article W is in a state where both ends in the horizontal direction perpendicular to the alignment direction Y are aligned by the pressing member 19 and the stopper member 17. Subsequently, the control device 30 controls the pinching device 8 to advance the pinching plates 80 in directions in which the pair of pinching plates 80 approach each other. As a result, the article group can be clamped from the alignment direction Y to bring the articles W into close contact with each other.

  Next, in step S4, the control device 30 controls the pushing device 9 to lower the pushing member 91 having a suction function so as to come into contact with the top surface of the clamped article group, so that the top surface of the article group is lowered. Adsorb. As a result, the article group is held by the pushing member 91.

  Next, in step S5, the control device 30 controls the floor opening / closing device 10 to drive the pair of floor plates 11 backward. As a result, an opening is formed directly under the article group located at the article placement position A.

  On the other hand, the control device 30 performs an exterior box arrangement process (step S6) and a guide device control process (step S7) in parallel with the processes of steps S1 to S5.

  In step S <b> 6, the control device 30 has previously placed the rod body 23 a of the restraining device 23 at the advanced position, and stops the outer box 110 carried by the outer box transport conveyor 22 at the box stop position U. . When the control device 30 receives a box detection signal from the box detection device 25, the control device 30 stops the transfer operation of the outer box transfer conveyor 22, raises the base 24, and moves the outer box 110 at the box stop position U to the boxing position P. To be located.

  Next, in step S <b> 7, the control device 30 controls the guide device 40 to displace the guide members 41 to 44 from the tilted posture to the suspended posture.

  Next, in step S <b> 8, the control device 30 controls the pushing device 9 to push the article group into the outer box 110 by lowering the pushing member 91 adsorbing the article group. At this time, the articles W at both ends of the article group slide through the surface of the pressure plate 80. In addition, the article group has four corners that pass through the inside of the four guide members 41 to 44, so that the gaps between the adjacent flaps F1 to F4 of the outer box 110 (the gaps between F1 and F2 and the gaps between F2 and F3). , The gap between F3 and F4, the gap between F4 and F1) is guided into the exterior box 110.

  Next, in step S9, the pushing device 9, the guide device 40, the floor opening / closing device 10 and the like are returned to their original states. For example, the pushing device 9 stops the suction function of the pushing member 91 and then raises the pushing member 91 to above the formation position of the article group. After the pushing member 91 is raised, the floor plate 11 is closed and the guide members 41 to 44 are returned to the inclined posture. Further, the pressing member 19 is returned to the retracted position, and the pressing plate 80 is retracted to return to the original position.

  And the control apparatus 30 performs the process of step S10 in parallel with step S9. In step S10, after the pedestal 24 is lowered and the outer box 110 containing the group of articles is positioned at the box stop position U, the rod body 23a of the restraining device 23 is retracted from the transport path, and the outer box transport conveyor 22 is transported. The operation is resumed and the outer box 110 is unloaded from the boxing device 100.

  Then, the same boxing operation as described above is newly repeated.

  In the boxing device 100, when the outer box 110 is disposed at the boxing position P below the floor board 11, the guide members 41 to 44 are displaced from the inclined posture to the hanging posture. Thereby, it is possible to prevent the guide members 41 to 44 from coming into contact with the inside of the four flaps F1 to F4 of the exterior box 110 and the flaps F1 to F4 from falling inward. In addition, with respect to the group of articles pushed by the pushing device 9, four gaps (F1 and F2 gaps, F2 and F3 gaps, F3 and F4 gaps) between the adjacent flaps (F1 to F4) of the outer box 110 are provided. A gap, a gap between F4 and F1, is hidden by each of the guide members 41 to 44 in the hanging posture. As a result, the group of articles pushed into the exterior box 110 passes through the inside of the four guide members 41 to 44 and is guided to the exterior box 110 without contacting the gaps between the flaps F1 to F4 of the exterior box 110. Therefore, the article can be prevented from being caught in the gap between the flaps F1 to F4, and the article can be accurately packed in the outer box 110.

  Further, since the four guide members 41 to 44 can be divided into two and operated by the rotation of the two rotation shafts 53a and 53b, the operation for rotating the four guide members 41 to 44 is performed. Two mechanisms and a rotary device (rotary actuator 56) are required, and the configuration is simplified.

  In addition, a guide member connecting component 59 having two guide members (41, 42 or 43, 44) is detachably attached to attachment members 57 fixed to the respective rotation shafts 53a, 53b. Therefore, there is a change in the boxed product to be produced (that is, a change in the type of article or the number of articles packed in one box), and the lateral direction of the outer box 110 (the article alignment direction Y, the axial direction of the rotary shafts 53a and 53b). ), There is a change in the horizontal dimension of the outer box 110 by preparing another guide member connecting part 59 corresponding to the changed dimension in advance and replacing it with the other. Can be easily accommodated. Therefore, it is possible to simplify the setup change work when the boxed product to be produced is changed and shorten the work time. Another guide member connecting part 59 to be replaced has a space between two guide members determined in accordance with the dimension in the left-right direction of the exterior box 110 after the change.

  Moreover, in this example, when there is a change in the boxed product to be produced and there is a change in the dimension in the front-rear direction (interval direction of the two rotating shafts 53a and 53b) of the outer box 110 in FIG. Since the clamp lever 49 of the interval adjusting mechanisms 4C and 4D can be loosened to change the interval between the two guide member rotating portions 4A and 4B (the interval between the guide members 41 and 42 and the guide members 43 and 44), the exterior It is possible to easily cope with a change in the size of the box 110 in the front-rear direction. Therefore, it is possible to simplify the setup change work when the boxed product to be produced is changed and shorten the work time.

[Second configuration example]
FIG. 8 is a perspective view showing a pedestal portion of the outer box lifting device in the boxing device of the second configuration example of the present embodiment.

A gear (not shown) is attached to one end of each of the connecting screw shafts 26 and 27, and a chain 28 is bridged between both gears. Further, one end of one of the connecting screw shafts 26 is extended and connected to the handle 29, and when the operator or the like turns the handle 29, the two connecting screw shafts 26 and 27 can be rotated simultaneously.

  Each of the connecting screw shafts 26 and 27 is formed by joining a right screw member SR formed with a right-hand thread and a left screw member SL formed with a left-hand screw at the center except for the end portions.

  A box guide plate 33 is attached to each right screw member SR of the connecting screw shafts 26 and 27 via a female screw member 34 fitted to the right screw member SR, and each left screw member SL is fitted to the female screw fitted thereto. A box guide plate 36 is mounted via a member 37.

  Therefore, according to the size of the exterior box 110 in the front-rear direction, the handle 29 can be turned to change or adjust the distance (distance) between the two box guide plates 33 and 36. For example, the interval between the box guide plates 33 and 36 is increased by turning the handle 29 clockwise (clockwise), and the interval between the box guide plates 33 and 36 is shortened by turning counterclockwise (counterclockwise). it can. The direction in which the outer box 110 is transported by the outer box conveyor 22 is the direction of the arrow y, and the space between the two box guide plates 33 and 36 is the transport path (passage) Q of the outer box 110 including the box stop position U. That is, the two box guide plates 33 and 36 are disposed to face each other with the conveyance path Q of the outer box 110 interposed therebetween.

  Further, attachment portions 35 and 38 are provided at the upper ends of the box guide plates 33 and 36 along the upper edge thereof. The attachment portions 35 and 38 are provided so as to extend horizontally from the upper ends of the box guide plates 33 and 36 to the side opposite to the conveyance path Q.

  The mounting portion 38 is mounted with the same restraining device 23 and the box detection device 25 as in the first configuration example, and the rear contact device 104 is mounted. The restraining device 23 and the box detecting device 25 are fixed on the slide plate 107. The slide plate 107 is configured to be slidable along two long holes 38b provided in the attachment portion 38 and extending in the outer box transport direction (y direction), and is fixed to the attachment portion 38 by tightening the clamp lever 108. Has been. By loosening the clamp lever 108, the positions of the restraining device 23 and the box detecting device 25 together with the slide plate 107 can be changed or adjusted along the elongated hole 38b.

The slide plate 105 is configured to be slidable along two elongated holes 38a provided in the mounting portion 38 in the outer box transport direction (y direction), and is fixed to the mounting portion 38 by tightening the clamp lever 106. Has been. By loosening the clamp lever 106, the position of the rear contact device 104 together with the slide plate 105 can be changed or adjusted along the elongated hole 38a.

  In this example, an attachment portion 38 is provided in which an attachment portion to which the restraining device 23 and the box detection device 25 are attached and an attachment portion to which the rear contact device 104 is attached are integrated. However, they may be provided separately.

  On the other hand, the front side contact device 101 is attached to the attachment portion 35. The front contact device 101 is fixed on the slide plate 102. The slide plate 102 is configured to be slidable along two elongated holes 35 a provided in the mounting portion 35 in the outer box transport direction (y direction), and is fixed to the mounting portion 35 by tightening the clamp lever 103. Has been. The position of the front contact device 101 together with the slide plate 102 can be changed or adjusted along the elongated hole 35a by loosening the clamp lever 103.

  In addition, the front side and the rear side in the front side and rear side contact devices 101 and 104 mean the front side and the rear side in the transport direction (y direction) of the exterior box 110. In this example, the restraining device 23 is also a front contact device, and has two front contact devices together with the front contact device 101.

  The front side and rear side contact devices 101 and 104 are configured by contact plates 101a and 104a and air-driven rotary actuators 101b and 104b that rotate the contact plates 101a and 104a by 90 degrees, respectively. The contact plates 101a and 104a are rotated 90 degrees as indicated by arrows a and b, respectively.

  In FIG. 8, the front and rear abutment devices 101 and 104 are provided when the outer box 110 (not shown) is in contact with the rod body 23 a of the restraining device 23 (that is, the outer box 110 is in the box stop position U). ) Shows a state in which the contact plates 101a and 104a are in the advanced position (contact position) where the contact plates 101a have advanced into the transport path Q. At this time, the contact plate 101a contacts the front surface of the outer box 110 in the transport direction. The contact plate 104a is in contact with the surface of the exterior box 110 on the rear side in the transport direction. From this state, when the contact plates 101a and 104a are rotated 90 degrees as indicated by arrows a and b by the rotary actuators 101b and 104b, the contact plates 101a and 104a are retracted from the transport path Q. Become position. Even when the pedestal 24A is raised and the outer box 110 is in the boxing position P, the bar body 23a and the contact plates 101a and 104a of the restraining device 23 are in the same state as shown in FIG.

  In the operation in the second configuration example, the operations of the front and rear contact devices 101 and 104 are added to the operation in the first configuration example. That is, only the exterior box arrangement process in step S6 and the carry-out process in step S10 in FIG. 7 are different, and the other processes are the same as those in the first configuration example. The front side and rear side contact devices 101 and 104 are also controlled by the control device 30.

  In the case of the second configuration example, in step S6, the control device 30 has previously placed the rod body 23a of the restraining device 23 in the advanced position, and the front side and rear side contact devices 101 and 104 are in the state of being advanced. The contact plates 101a and 104a are in the retracted position. In this state, the exterior box 110 carried in by the exterior box transport conveyor 22 comes into contact with the rod body 23a of the restraining device 23 and stops at the box stop position U. When the control device 30 receives a box detection signal from the box detection device 25, the control device 30 stops the transport operation of the outer box transport conveyor 22, and rotates the contact plates 101a and 104a to the advanced position, thereby the outer box 110. It is made to contact from the front and back in the conveyance direction. Subsequently, the pedestal 24A is raised by an elevating device (not shown), and the outer box 110 at the box stop position U is positioned at the boxing position P.

  In step S10, the control device 30 lowers the pedestal 24A to place the outer box 110 containing the article group in the box stop position U, and then retracts the rod body 23a of the restraining device 23 from the transport path Q. At the same time, the contact plates 101a and 104a are rotated to the retracted position, the conveying operation of the outer box conveying conveyor 22 is restarted, and the outer box 110 is carried out of the boxing device 100.

  In the case of this second configuration example, the same effects as in the case of the first configuration example can be obtained, and on the pedestal 24A, the exterior box 110 is disposed on the front surface in the transport direction with the rod body 23a and the contact plate 101a. Are supported at two locations that are in contact with each other in the horizontal direction, and the contact plate 104a is in contact with and supported by the rear surface. That is, since two opposing sides of the rectangular outer box 110 in plan view are supported at three locations, the outer box 110 can be accurately positioned and positioned at the boxing position P. Accordingly, the four corners of the outer box 110 can be accurately associated with the guide members 41 to 44, and when the articles are pushed into the outer box 110, the articles are placed in the gaps between the flaps F <b> 1 to F <b> 4 of the outer box 110. It is possible to prevent the article from being caught and to pack the articles into the outer box 110 more accurately.

  In addition, about the front side contact apparatus 101, you may make it make the contact plate 101a advance / retreat operation at the same timing as the advance / retreat operation of the rod body 23a of the restraining device 23. That is, the contact plate 101a may be in the advanced position before the outer box 110 is carried in. In this case, the front contact device 101 is a stop device that stops the outer box 110 conveyed by the outer box transport conveyor 22 at the box stop position U together with the control device 23, and the front contact device 101 is stopped. Similarly to 23, an air cylinder may be used.

  Further, the restraining device 23 may have a configuration using a contact plate and a rotary actuator, similarly to the front side and rear side contact devices 101 and 104.

  In addition, when there is a change in the boxed product to be produced and there is a change in the dimension of the exterior box 110 in the front-rear direction (see FIG. 1), the handle 29 is turned to guide the two boxes according to the changed dimension. The distance between the plates 33 and 36 can be changed. Further, when there is a change in the dimension in the left-right direction (see FIG. 1) of the outer box 110, the front contact device 101 is operated by operating the clamp levers 103, 106, 108 according to the changed dimension. The positions of the rear contact device 104, the restraining device 23, and the box detecting device 25 can be changed. Therefore, it is possible to simplify the setup change work when the boxed product to be produced is changed and shorten the work time.
