JP 2006-232321 A

  In order to convey articles on the conveyor of the article insertion device, the articles must be positioned one by one in a plurality of conveyance buckets attached to the conveyor belt. This is because when the article is pushed by the pusher, the conveying bucket lifts the article from the conveyor belt so that the pusher does not contact the conveyor belt.

  However, for example, single-pieces inserted into an envelope of direct mail have various sizes and shapes. For this reason, it is difficult to change the conveying buckets with different dimensions each time the type of the sheet is changed, or to increase or decrease the pitch for arranging the plurality of conveying buckets on the conveyor belt.

  Accordingly, an object of the present invention is to provide a collating and conveying apparatus that can be positioned as desired in the process of conveying a sheet regardless of the size and shape of the sheet.

  In order to achieve the above object, the present invention provides a plurality of sheets that are pushed into the bag body by a pusher that operates in a direction crossing the arrangement direction in a process in which the plurality of bag bodies arranged in a row are conveyed in the arrangement direction. A collating and conveying apparatus for conveying an object, wherein the sheet is supported by a bottom surface material, and the sheet material is opposed to the bag body by a plurality of collating claws protruding upward from the bottom surface material. A collating conveyor that conveys the single sheet by moving the collating claws in the alignment direction, and a guide member that guides the single sheet conveyed to the collating conveyor upward. A plurality of convex portions that are provided along the travel of the collating claw and that receive the sheet material guided by the guide member at a position higher than the bottom material of the collating conveyor, And a loading conveyor that runs at a speed synchronized with the claw Between the plurality of protrusions of the mounting conveyor is characterized in that securing a space capable of passing through the pusher.

  Further, according to the present invention, the collating conveyor includes two claw belts in which the plurality of claw claws are provided at equal intervals, and two driving means for driving the two claw belts, respectively. The two driving means cause the two claw belts to travel in the same phase with each other or relatively reversely feed.

  The collating device according to the present invention is a process in which the collating conveyor travels the collating claw, and the sheet material is conveyed along with the collating claw in the direction in which a plurality of bags are arranged, and receives frictional force from the bottom material. It is pressed moderately on the collating nail. As a result, the sheet is positioned on the collating conveyor in close contact with the collating claw. In addition, since the collating claw protrudes above the bottom material, the sheet is guided above the bottom material by the guide member, but the collating claw travels without detaching from the collating claw. It is received by the several convex part of the mounting conveyor installed along.

  In this state, the pusher operating in the direction crossing the alignment direction can pass through the gaps between the plurality of convex portions, so that the sheet can be transferred from the mounting conveyor to the bag body without unnecessary contact with the mounting conveyor. Can be extruded. In this way, the single wafer extruded by the pusher slides relative to the convex portion of the loading conveyor, but the loading conveyor is traveling at a speed that synchronizes the convex portion with the collating conveyor. Is maintained in a posture facing the bag body by the collating claw.

  Therefore, according to the collating and transporting apparatus, a transport bucket or the like is not required for positioning a sheet, and even if the type of sheet is frequently changed, regardless of its size or shape. Any type of single wafer can be positioned and conveyed as desired.

  Furthermore, according to the collating and conveying apparatus according to the present invention, when the two driving units run the two claw belts in the same phase, the positions of the respective claw claws of the two claw belts are aligned. The individual sheets received by the convex portion of the placing conveyor are positioned in a posture facing the bag body by the two collating claws. In addition, since the two collating claws abut against each individual sheet at two points, it is possible to restrict the sheet from being inclined with respect to the bag body.

  In addition, when the collating and conveying apparatus is urgently stopped for some reason, the sheet may be detached from the two collating claws due to its inertial force. In this state, the two driving units relatively reversely feed the two claw belts, so that the claw of one claw belt of the two claw belts is directed toward the claw of the other claw belt. You can push things back. Then, when the sheet material hits the claw of the other claw belt, if the two driving means resume the operation of running the two claw belts in the same phase, they are received by the convex portion of the loading conveyor. The stopped individual sheets are again positioned as described above.

  In this way, since the posture and arrangement of the sheet can be quickly returned without manual operation immediately after an emergency stop, the collating and conveying apparatus has the advantage that the time for stopping the operation can be minimized. There is.

  FIG. 1 shows a collating and conveying device 3 that conveys a plurality of single-piece objects 2 that are pushed into the bag body 1 in a process in which a plurality of bag bodies 1 arranged in a row are conveyed in the arrangement direction. The bag 1 is assumed to be transparent for convenience of explanation. FIG. 2 shows an example in which the collating and conveying device 3 conveys the sheet 2 in a posture facing the opening 11 of the bag body 1. FIG. 3 shows a process in which the pusher 5 with the nail 51 placed on the sheet 2 pushes the sheet 2 into the bag 1.

  An arrow T indicates the conveyance direction in which the sheet 2 is conveyed. The pusher 5 operates in a direction crossing the arrangement direction of the plurality of bag bodies 1, and an arrow P indicates a direction in which the pusher 5 advances to the bag body 1. Reference numeral 12 in FIG. 2 indicates a gap for releasing the claw 51 of the pusher 5. The code | symbol 13 of FIG. 3 has pointed out the member which guides the sheet | seat 2 to the back of the bag body 1. FIG. Details will be described in the following examples.

  As shown in FIGS. 4 and 5 (a), 5 (b), the collating and conveying apparatus 3 includes a collating conveyor in which two endless claw belts 61 and 62 are wound around four pulleys 63 to 66, respectively. 6, a pair of guide members 7 provided on both sides of the collating conveyor 6, and a mounting conveyor 8 in which two endless convex belts 81 and 82 are wound around four pulleys 83 to 86, respectively. .

  In the collating conveyor 6, a bottom material 9 that slidably supports the claw belts 61 and 62 is attached to the inside of the housing 31 of the collating conveyance device 3, and protrudes above the bottom material 9 to the claw belts 61 and 62. A plurality of collating claws 10 are provided. The plurality of collating claws 10 are prisms made of synthetic resin, and are arranged at equal intervals in the transport direction. The two pulleys 63 and 64 are connected to the two drive means 14 and 15 via drive shafts 67 and 68 that are supported by the housing 31, respectively. The driving means 14 and 15 rotate the pulleys 63 and 64 to cause the claw belts 61 and 62 to travel in the transport direction or to relatively reversely feed the claw belts 61 and 62. This will be described later. The drive means 14 and 15 are preferably servo motors.

  The loading conveyor 8 is installed along the travel of the claw belts 61 and 62 of the collating conveyor 6. The two pulleys 83 and 84 are connected to the drive shaft 68, and the convex belts 81 and 82 are driven by the drive unit 15 together with the claw belt 62 of the collating conveyor 6. The convex belts 81 and 82 are provided with a plurality of convex portions 16 that receive the sheet 2 at a position higher than the bottom surface material 9. The plurality of convex portions 16 are synthetic resin pedestals arranged at equal intervals in the transport direction. A space 12 is formed between the plurality of convex portions 16.

  As shown in FIGS. 4 and 6, the guide member 7 includes a base portion 71 connected to the bottom surface material 9, side pieces 72 standing outside the pulleys 85 and 86 of the loading conveyor 8, and a forward direction in the conveying direction. It is the steel plate in which the inclined piece 73 which goes up as it goes is formed. The base 71 can slidably support the sheet 2 at the same height as the bottom material 9. The upper end of the inclined piece 73 extends to the same height as the convex portion 16 or a position slightly higher than the convex portion 16.

  The bag 1 shown in FIGS. 1 and 2 is an envelope in which a paste margin piece 17 extends from the lower edge of the opening 11, and is conveyed by a suction conveyor 18 adjacent to the collating conveyor 6. The suction conveyor 18 includes endless belts 181 and 182 on which the adhesive piece 17 and the body portion 19 of the bag body 1 are placed, respectively. Ventilation holes 183 are formed at appropriate positions, and the negative pressure generated at the intake port of an air blower or the like is guided to the ventilation holes 183, whereby the adhesive margin piece 17 and the body portion 19 are adsorbed to the endless belts 181 and 182, respectively. The

  Since the endless belt 181 is disposed lower than the endless belt 182, the paste margin piece 17 of the bag body 1 conveyed by the suction conveyor 18 is deformed so as to be inclined downward from the opening 11, and the bottom material 9 and the lower side of the inclined plate 184 provided between the suction conveyor 18 and the suction conveyor 18. Reference numeral 185 indicates an inclined bar that compensates between the endless belts 181 and 182.

  Next, the operation of the collating transport device 3 will be described. The drawings refer to FIGS. 1 to 4 unless otherwise specified.

  As shown in FIG. 7, the collating claws 10 of the two claw belts 61 and 62 are aligned in the arrow P direction. In this state, the two driving means 14 and 15 are activated simultaneously. The two driving means 14 and 15 are electrically synchronized with each other, and the pawl belts 61 and 62 travel in the same phase. In other words, the traveling speeds of the claw belts 61 and 62 coincide with each other, and the collating claws 10 are maintained in the direction of the arrow P.

  On the other hand, on the starting end of the collating conveyor 6, the single or multiple sheets 2 are placed. In this step, the bottom material 9 receives the sheet 2 supplied from the feeder 19 installed on the side of the housing 31. Then, in the process in which the collating conveyor 6 runs the claw belts 61 and 62, the collating claw 10 hits the sheet 2, and the sheet 2 is conveyed according to the collating claw 10. Moreover, since the single-piece 2 receives frictional force from the bottom material 9, it is appropriately pressed against the two collating claws 10. Thereby, the sheet 2 is positioned on the claw belts 61 and 62 of the collating conveyor 6 in a posture in close contact with the collating claw 10 and facing the opening 11 of the bag body 1.

  Further, the sheet 2 conveyed according to the collating claw 10 gets on the inclined piece 73 from the base 71 of the guide member 7 when approaching the pulleys 85 and 86 of the loading conveyor 8, and follows the inclined piece 73 to the bottom surface material 9. It is guided upwards. Immediately after this, the sheet 2 passes through the upper end of the inclined piece 73 and is received by the plurality of convex portions 16 of the placing conveyor 8 as shown in FIG. Further, the collating claw 10 protrudes above the guide member 7. For this reason, the sheet 2 is not removed from the collating claw 10 while being guided by the inclined piece 73 and received by the convex portion 16 of the loading conveyor 8. Continue to be transported according to 10.

  As described above, the sheet 2 is pushed into the opening 11 of the bag 1 by the pusher 5 moving forward to the bag 1 in a state where the sheet 2 is received by the convex portion 16. Moreover, since the nail | claw 51 of the pusher 5 can pass the space | gap 12 between the some convex parts 16, it does not contact the mounting conveyor 8 unnecessarily. Therefore, the collating / conveying device 3 does not require a conveying bucket or the like to position the sheet 2. Moreover, even if the type of the sheet 2 is frequently changed, the collating and conveying device 3 positions and conveys the sheets 2 in all forms as described above regardless of the size or shape. Can do.

  Further, for example, when the collating and conveying device 3 is brought to an emergency stop due to a failure such as the supply of the bag 1 being interrupted, the single-piece 2 is collated with its claws by its inertia force as shown in FIG. There is a possibility of leaving from 10. Actually, a plurality of sheets 2 are superposed on each other, and the lowermost sheet among these is subjected to the frictional force of the convex part 16, but the sheet on top of it is a collating nail. There is a strong tendency to leave 10. In such a case, the two drive means 14 and 15 relatively reversely feed the claw belts 61 and 62 as follows.

  That is, in a state where the driving unit 15 is stopped, the driving unit 14 is rotated in the reverse direction, and the claw belt 61 is fed back in the conveyance direction. As a result, as shown in FIG. 5C, the collating claw 10 of the nail belt 61 pushes the sheet 2 back until it hits the collating claw 10 of the nail belt 62. Then, the drive means 14 is rotated forward, and the drive means 14 is stopped when the respective claws 10 of the claw belts 61 and 62 are aligned in the direction of the arrow P as shown in FIG. As a result, the two collating claws 10 are abutted against the sheet material 2, and the sheet material 2 can be returned to the posture facing the opening 11 of the bag body 1.

  Further, since the two collating claws 10 abut against each individual sheet 2 at two points, even if the sheet 2 is inclined with respect to the bag 1 as shown in FIG. Can be corrected to a posture that directly faces the opening 11 of the bag body 1 as shown in FIG. As described above, the collating and conveying apparatus 3 can quickly return the posture and arrangement of the sheet 2 immediately after an emergency stop without relying on a human hand, and therefore has an advantage that the time for stopping the operation can be minimized. There is.

  It should be noted that the present invention can be implemented in a mode in which various improvements, modifications, or variations are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention. The suction conveyor 18 is not an essential element of the present invention, and the bag body 1 may be transported by transfer other than the conveyor as long as it fulfills the function of transporting the bag body 1. Further, instead of the claw belts 61 and 62 or the convex belts 81 and 82, a chain may be applied. As shown in FIG. 7, a rib 69 may be provided on the collating claw 10 of the claw belt 62, and a guide piece 87 aligned with the two collating claws 10 may be provided on the convex portion 16.

  The collating conveyor and the loading conveyor applied to the collating and conveying apparatus according to the present invention are intermittently used to stop the bag and the sheet when the pusher of the insertion device pushes the sheet into the bag. You may drive. Alternatively, the collating conveyor and the loading conveyor may continue the continuous operation. In this case, the pusher is moved at a speed synchronized with the sheet, and in this process, the pusher pushes the sheet into the bag.
