In addition, the present invention relates to a transport machine capable of increasing the processing density by increasing the transport density.

In recent years, documents, magazines, books, CD cases, etc. are transported by courier or mail.
In this transportation, documents, magazines, and the like are stored in a large envelope for delivery to home or mail made of vinyl or paper, or in a case such as cardboard or cardboard. Also, magazines and the like are sometimes not transported in envelopes or cases, but are transported only in a band or as they are.
The large envelopes and cases (including postcards and small envelopes) described above are classified by a dedicated transport machine.

(Conventional technology)
Next, a conventional conveyor will be described with reference to the drawings.
FIG. 5a shows a schematic plan view of a conventional transfer machine.
FIG. 5b shows a schematic front view of a conventional transfer machine.
5A and 5B, a conventional transport machine 100 includes a housing 110, a guide rail 150 provided in the housing 110 and formed in an endless loop shape having a straight portion and a curved portion, and a guide rail 150. A plurality of transport boxes 120 that are suspended and circulate and move along an endless loop path are provided.

(Casing)
The casing 110 includes a plurality of sorting section casings 111 and four supply section casings 112.
The sorting unit housing 111 includes a plurality of stacking units 113 for stacking the transport target objects 101 discharged from the transport box 120. Further, the supply unit housing 112 transports the transported object 101 that has been transported, a feeder 12 that feeds the stacked transported objects 101 one by one, a belt 14 that transports the supplied transported object 101, and the like. Transfer means 13 for transferring to the box 120 is provided.
In general, the stacking unit 113 and the transfer means 13 are disposed in a straight conveyance portion of the conveyance box 120. Examples of the conveyance object 101 include postcards, envelopes, documents, magazines, books, and CD cases, but are not limited thereto.

(Transport box)
FIG. 6 a shows a schematic front view of a transport box according to a conventional example.
FIG. 6B is a schematic side view of the transport box according to the conventional example viewed from the outer side.
In FIGS. 6 a and 6 b, the transport box 120 has a substantially rectangular box shape and includes four storage chambers 121 that are partitioned at equal intervals by a partition plate 122. As shown in FIG. 6b, the transport box 120 has a parallelogram shape with its upper part protruding in the transport direction when viewed from the side. If it does in this way, the conveyance target object 101 can be discharged | emitted smoothly.
Moreover, the conveyance box 120 is suspended by the guide rail 150 via the connected conveyance trolley (not shown). Here, the transport box 120 is supported so that the center of gravity of the transport box 120 is located almost directly below the guide rail 150 when viewed from above.

The transfer box 120 is formed with a transfer port 123 for throwing the transfer object 101 on the side surface on the outer side, and is a rotary type as a discharge means for discharging the transfer object 101 to the bottom of each storage chamber 121. The bottom lid 8 is provided.
Each of the storage chambers 121 has a conveyance direction width W (constant) in the entire region viewed from the front direction. Therefore, the transfer direction width of the transfer space 124 used when the transfer object 101 is transferred is also W (constant) in the entire region viewed from the front direction.

(Transfer means)
For example, as shown in FIG. 7, the transfer means 13 includes two belts 132 and 133 that are hung on a plurality of rollers 134 that are transported while sandwiching the transport object 101, and a tip on the transport direction side. The roller 135 and the swinging means (not shown) for rotating the transfer means 13 according to the transport speed and timing of the transport box 120 are provided. Thus, since the transfer means 13 swings in accordance with the transfer speed and timing of the transfer box 120, the transfer time (the time from the transfer start time to the transfer completion time) can be lengthened.

Next, the operation of the conveyor 100 will be described.
In the transport device 100, the supply device 12 supplies the transport object 101 to the belt 14 one by one, and the belt 14 transports the transfer device 13. Subsequently, the transfer means 13 transfers the transfer object 101 to a predetermined storage chamber 121 of the transfer box 120. In general, the most upstream (first) transfer means 13 transfers the transport object 101 to the transport direction side (first) storage chamber 121, and then the downstream side. The (second, third, fourth) transfer means 13 sequentially transfers the transfer object 101 to the (second, third, fourth) storage chamber 121 on the side opposite to the transfer direction.

FIG. 7 is a cross-sectional view seen from above for explaining the transfer operation of the transfer means of the conventional example, (a) is a schematic view when transfer is started, and (b) is transfer. (C) is a schematic diagram when transfer is completed, and (d) is a schematic diagram in a transfer preparation state.
In FIG. 7A, the transfer means 13 is rotated by the swinging means so that the speed component in the transport direction at the tip of the transport target object 10 to be pushed out is substantially the same as the transport speed of the transport box 120. ing. The transport object 101 is transported by the two belts 132 and 133. The time when the leading end of the conveyance object 101 reaches the transfer port 123 is the transfer start time.

  Next, in FIG. 7B, the transfer means 13 continues to rotate and transfer, and the transfer object 101 has moved into the transfer space 124 of the storage chamber 121. As shown in FIG. 7C, the transfer unit 13 continues the rotation and the conveyance until the last part of the conveyance target 101 reaches the transfer port 123. In addition, the time when the last part of the conveyance object 101 reaches the transfer port 123 is the transfer completion time point.

Next, when the transfer is completed, the transfer means 13 decelerates the rotation speed and stops. Subsequently, the transfer means 13 rotates in the return direction, stops and waits for the next transfer as shown in FIG.
As shown in FIG. 6 a, the transport box 120 does not have a side plate on the inward side facing the transfer port 123. Instead of this side plate, a receiving side plate 127 is fixed at a position corresponding to the transfer means 13 of the housing 110. Therefore, the transfer object 101 that has moved from the transfer means 13 through the transfer port 123 into the transfer box 120 at high speed collides with the receiving side plate 127 and falls, and is stored in the transfer box 120. That is, since the side plate 127 receives the impact of the conveyance object 101 thrown into the conveyance box 120 at a high speed, the mechanical strength of the conveyance box 120 and the conveyance carriage 106 can be reduced. Further, the stored conveyance target 101 is locked by the outer side plate 126 and the inner side plate 124 so as not to jump out of the transfer port 123 and the like.

Next, the transport machine 100 transports the transport box 120 on which the transport target object 101 is transferred, to the sorting unit casing 111 along the guide rails 150 by driving means (not shown).
And the conveying machine 100 discharges | emits the conveyance target object 101 to the stacking part 113 according to the destination by opening the bottom cover 8. FIG. That is, the transport device 100 can classify the transport target object 101 by destination while transporting the transport target object 101.

By the way, as shown in FIG. 6b, when the width in the conveyance direction of each storage chamber 121 is W and the thickness in the conveyance direction of the object to be conveyed 101 is t, the conveyance direction gap Δ of the transfer space 124 is Δ = W−. t (mm).
Further, the conveyance density of the conveyance box 120 is t / W (%) when the thickness of the partition plate 122 is negligible.
Furthermore, the transfer time required to transfer the transfer object 101 in a stable state is proportional to Δ and inversely proportional to v, where v is the transfer speed of the transfer box 120.

From the above relationship, if the transport density is increased for the purpose of improving the transport capability of the transport box 120, Δ is decreased, the transfer time is shortened, and the transfer stability is lowered. Similarly, when the transport speed v is increased for the purpose of improving the processing capability of the transport machine 100, Δ is decreased, the transfer time is shortened, and the transfer stability is lowered.
Further, when the transfer speed of the transfer means 13 is constant, the transfer time increases as the length of the transfer target 101 increases in the transfer direction, so that the transfer direction gap Δ is increased or the transfer speed is increased. It is necessary to slow down v.

In addition, since the processing capacity of the transport machine 100 increases when the transport density is increased, various techniques for increasing the transport density have been developed.
For example, Patent Document 1 discloses a technique of a conveyance interval variable type conveyance machine. This transfer machine is provided with a transfer interval variable mechanism that makes the interval of the transfer box variable at the boundary portion between the straight line portion and the curved portion of the endless loop path, thereby increasing the mounting density of the transfer box in the straight line portion. Conveying speed in is minimized. By doing in this way, the processing capacity of a conveyed product does not fall, and the transfer operation and discharge operation | movement of a conveyed product are stabilized.

However, this transfer interval variable type transfer machine has been able to improve the processing capability by realizing high-density transfer in the straight portion, but further improvement of the processing capability is required in the market.
Further, in the above high-density transport, the transport boxes are almost in contact with each other, and in order to further improve the processing capacity of the transport machine, the transport direction gap Δ of the storage chamber is narrowed or the transport of the transport box is performed. It is necessary to increase the speed v.
JP 2003-237926 A (Claim 1, FIGS. 2, 5)

However, if the conveyance direction gap Δ in the storage chamber of the transfer box is reduced or the transfer speed v of the transfer box of the transfer machine is increased, the transfer object is moved before the transfer of the transfer object is completed. There is a problem that the transfer plate is in contact with the partition plate on the side opposite to the conveyance direction of the storage chamber, and transfer is not stable or cannot be transferred.
Further, if the transport speed v of the transport box is increased or the transport density is increased, the transfer cycle time is shortened, so that it is necessary to swing the transfer means at a high speed. However, in order to speed up operations such as sudden acceleration rotation, sudden stop, and sudden acceleration rotation in the reverse direction of the transfer means, the conventional swing means has structural limitations and cannot cope with the high speed. There was a problem.
In particular, when the object to be transported becomes large and becomes longer in the transfer direction, the transfer time becomes longer, and this increased transfer time becomes a bottleneck, and there is a problem that the processing capacity of the transporter cannot be improved. .

  In order to solve the above problems, the present invention aims to stabilize the transfer operation of the transfer object and increase the transfer speed by transferring the transfer object while moving the transfer means along with the transfer box.

FIG. 1: has shown the schematic front view of the conveying machine concerning embodiment of this invention.
In FIG. 1, the transport machine 1 is different from the transport machine 100 of the conventional example in that a transfer device 2 is provided instead of the transfer means 13. Other constituent elements are substantially the same as those of the conventional transfer machine 100.
Therefore, in FIG. 1, the same components as those in FIG. 5a are denoted by the same reference numerals, and detailed description thereof is omitted.

FIG. 2 a shows a schematic enlarged front view of the main part of the transfer device in the transporter according to the embodiment of the present invention.

In FIG. 2 a, the parallel guide rail 41 on the front side is omitted for easy understanding of the structure of the parallel carriage 42. Moreover, in FIG. 2c, the parallel running direction side guide plate 33 is illustrated by a dotted line for easy understanding.

(Transfer means)
The transfer means 3 includes a base plate 31, an anti-parallel running direction side guide plate 32, a parallel running direction side guide plate 33, a conveyance / discharge belt 34, and a roller 35.
The base plate 31 has a rectangular shape, and the bottom surface is supported by the parallel carriage 42 of the parallel running means 4 by a connecting member 426. Further, the lateral width of the base plate 31 is approximately the same as the pitch of the transport box 120.
The base plate 31 of the present embodiment has a smooth surface so that the conveyance object 101 can easily slide, but is not limited to this structure. For example, a belt conveyor (not shown) It is good also as a structure which moves and the conveyance target object 101 moves to the discharge port side.

The anti-parallel running direction side guide plate 32 has a rectangular shape, and is provided at an end of the base plate 31 on the parallel running direction side with an upper portion inclined to the parallel running direction side. This inclination angle is substantially the same as the inclination angle of the transfer port 123 of the transport box 120. The guide plate 32 has a length that does not run on the roller 35 so as not to hinder the movement of the roller 35.
In the anti-parallel running direction side guide plate 32, the parallel running direction side surface is a guide surface, and guides the conveyance object 101 to which the previous transfer means 3 is transferred from the anti-parallel running direction side.

The parallel running direction side guide plate 33 includes a triangular conveyance guide plate 331 and a discharge guide plate 332. The conveyance guide plate 331 is located above the conveyance / discharge belt 34 on the receiving port side and in the parallel running direction side, and further, with the upper portion inclined to the parallel running direction side, via an arm (not shown), It is attached to the base plate 31.

Thus, it is attached to the connecting arm 346 via a connecting plate (not shown). Therefore, the discharge guide plate 332 rotates together with the connecting arm 346.
By providing such a parallel running direction side guide plate 33, it is possible to reliably receive and discharge the conveyance target 101.

The conveyance / discharge belt 34 includes a driving roller 341, a passive roller 342, an intermediate roller 343, an urging roller 344, a belt 345, and a connecting arm 346.
The drive roller 341 is pivotally supported at the end of the base plate 31 on the side of the parallel running direction and on the receiving side. The drive roller 341 rotates when a pinion (not shown) provided at the lower part moves a rack (not shown) provided at the upper part of the guide rail 41 for parallel running in the parallel running direction.

  The passive roller 342 is rotatably supported at the end of the base plate 31 on the side opposite to the running direction and on the discharge port side. The passive roller 343 is pivotally supported by the intermediate roller 343 in a state in which the passive roller 343 is urged clockwise through the connecting arm 346. If it does in this way, the conveyance target object 101 from which thickness differs can be discharged | emitted reliably.

Preferably, although not shown, when the conveying / discharge belt 34 located between the passive roller 342 and the intermediate roller 343 receives a predetermined external force in the parallel running direction, it further rotates in the parallel running direction. It is good to have a configuration to In this case, for example, the transfer is not performed normally, and the transfer means 3 passes through the parallel transfer transfer area 44 in a state where the transfer target object 101 extends over the transfer box 120 and the transfer means 3. However, it is possible to prevent such a problem that the conveyance object 101 is damaged.
The protection function for protecting the conveyance object 101 is not limited to the above configuration. For example, when the roller 35 receives a predetermined external force in the anti-parallel direction side, it rotates in the anti-parallel direction side. It is good also as a structure.

The intermediate roller 343 is pivotally supported at a substantially central portion of the base plate 31 while being sandwiched between the belts 345.
The urging roller 344 is provided in the vicinity of the intermediate roller 343 in a state of being urged in the opposite running direction side, and pushes the belt 345 from the running direction side to apply a predetermined tension to the belt 345.
The belt 345 is hung on the driving roller 341 and the passive roller 342 and exhibits the functions of a conveying belt and a discharging belt. Since the belt 345 is shared, the manufacturing cost can be reduced. .
Further, the conveyance / discharge belt 34 is provided in a state where the upper portion is inclined to the side of the parallel running direction at substantially the same angle as the inclination angle of the transfer port 123.

  The roller 35 is rotatably supported at the end of the base plate 31 on the side of the parallel running direction and on the discharge port side so that the upper part is inclined to the side of the parallel running direction at substantially the same angle as the tilt angle of the transfer port 123. Yes.

In this embodiment, the transfer means 3 forms a receiving space 36 surrounded by the base plate 31, the conveyance / discharge belt 34, the parallel running direction side guide plate 33, and the counter parallel running direction side guide plate 32.
The transfer means 3 configured as described above can reliably receive the conveyance object 101 from the belt 14 even while running in parallel, and can reliably discharge the conveyance object 101 without damaging it. it can.

(Parallel means)
The parallel running means 4 includes a parallel running guide rail 41, a parallel running carriage 42, and a screw 43 as a driving means for moving the parallel running carriage 42.
The parallel running guide rail 41 is a pair of endless loop rails formed so as to face each other and a groove 411 into which the roller bearing 422 is inserted in the horizontal direction, and a gap in which the roller bearings 423 and 424 are inserted in the vertical direction is formed. In the opened state, it is supported by the supply unit housing 112 via a support member (not shown).

  Further, the parallel running guide rail 41 forms an oval path when viewed from the front direction, and an area corresponding to the upper straight portion of the oval is defined as a parallel running transfer area 44. By setting the length of the parallel transfer transfer area 44, the transfer time can be freely adjusted, and the transfer speed of the transfer box 120 can be increased. Further, the structure of the parallel running means 4 can be simplified by the elliptical parallel running guide rail 41, and the manufacturing cost can be reduced.

The parallel carriage 42 includes a curved rectangular bar-shaped carriage main body 421, a pair of roller bearings 422 projecting horizontally from an end of the carriage main body 421 in the anti-parallel running direction, and an end of the carriage main body 421 in the anti-parallel running direction. Roller bearing 423 projecting upward from the center, two-stage roller bearings 424 and 425 projecting downward from the center of the cart body 421, and projecting upward from the center of the cart body 421 It consists of a connecting member 426. In the parallel carriage 42, a pair of roller bearings 422 connects the carriage main bodies 421 so as to be rotatable. Further, the lower roller bearing 425 is inserted into the groove of the screw 43.
The position of the parallel carriage 42 is restricted by a pair of roller bearings 422 and roller bearings 423 and 424, and can move only in the parallel direction along the parallel guide rail 41.

The screw 43 as the driving means is rotated by a motor and a control unit (not shown), and the roller bearing 425 fitted in the groove of the screw 43 is circulated and moved in the parallel running direction. Further, the rotation speed and the rotation timing of the screw 43 are controlled by the control unit. By doing in this way, in the parallel transfer transfer area 44, the transfer means 3 moves side by side with the transport box 120 in synchronization with the transport speed and timing of the transport box 120.
Thus, the parallel running means 4 can continuously run a plurality of transfer means 3 along the endless loop path, and can increase the parallel running speed easily. The parallel speed and timing can be controlled.

Next, the operation of the conveyor 1 having the above configuration will be described with reference to the drawings.
Fig.3 (a)-FIG.3 (i) have shown the schematic of the principal part for demonstrating the state to which the transfer apparatus in the conveying machine concerning embodiment of this invention transfers a conveyance target object. .
The transport machine 1 is different from the conventional transport machine 100 in that a transfer device 2 is provided instead of the transfer means 13. Therefore, the operation not related to the transfer device 2 is almost the same as the operation of the transporter 100.

In FIG. 3A, the transport machine 1 is transporting the transport box 120 at a predetermined transport speed. Further, the transfer device 2 moves the transfer means 3 to the transfer box at the timing when the parallel means 4 is at the same speed as the transfer speed and the discharged transfer object 101 is transferred to the predetermined storage chamber 123. I'm running with 120.
In addition, the transfer means 3 is in a state in which the conveyance / discharge belt 34 rotates and can accept the conveyance object 101 conveyed by the belt 14. This position is the start position of the parallel transfer area 44.

  Next, in FIG. 3 (b), the belt 14 conveys the conveyance object 101, and the leading end of the conveyance object 101 enters the receiving space 36 of the transfer means 3, and subsequently in FIG. 3 (c). The transport object 101 further enters the receiving space 36 of the transfer means 3. Here, even if the front end of the conveyance target 101 is in contact with the conveyance / discharge belt 34, the conveyance / discharge belt 34 is rotating, so that a problem such as damage to the conveyance target 101 is prevented. Can do.

Next, in FIG. 3D, the rearmost end of the conveyance target object 101 is conveyed by the belt 14, and the front end portion of the conveyance target object 101 is in contact with the conveyance / discharge belt 34, and the discharge port side It is conveyed to.
Although not shown in the figure, even if the end of the transport object 101 is away from the belt 14, the transport object 101 is not affected by the inertial force received from the belt 14 and the transport / discharge belt 34. Is conveyed to the discharge port side. At this time, since the conveyance object 101 is guided by the parallel running direction side guide plate 33, a part of the conveyance object 101 comes into contact with the conveyance / discharge belt 34 and is reliably conveyed to the discharge port side.

  Next, in FIG. 3 (e), when the conveyance object 101 is sandwiched between the anti-parallel running direction side guide plate 32 and the conveyance / discharge belt 34, the connecting arm 346 is moved according to the thickness of the conveyance object 101. It rotates counterclockwise. Subsequently, as shown in FIGS. 3F to 3H, the transfer means 3 continues to rotate even when the connecting arm 346 is rotated, and the transport object 101 is transported to the transport / discharge belt 34. It moves to the predetermined | prescribed storage chamber 123 of the conveyance box 120 with the moving speed of. Here, since the transfer means 3 is running side by side with the transfer box 120 as described above, the transfer object 101 can be transferred stably.

Next, in FIG. 3I, in the transfer means 3, the connecting arm 346 rotates in the clockwise direction when the rear end of the conveyance object 101 leaves the conveyance / discharge belt 34. Further, the transfer object 101 completely enters the storage chamber 123 by the inertial force received from the transfer / discharge belt 34, and the transfer operation of one transfer object 101 is completed.
The position where the transfer operation is completed is in the parallel transfer region 44, and the transfer operation can be performed safely and reliably.

Thus, since the transfer means 3 of the transfer apparatus 2 transfers the transfer target object 101 while running along with the transfer box 120, the transfer device 1 can transfer the transfer object in a reliable and stable state. . Furthermore, the conveyance direction width W of each storage chamber 121 of the conveyance box 120 can be narrowed, and the conveyance density can be made dense.
Further, since the transfer of the transfer object 101 is performed in a state where the transfer box 120 and the transfer means 3 are relatively stationary, the transfer speed of the transfer box 120 can be increased.
That is, the conveyor 1 can stabilize the transfer operation and can greatly improve the processing capability.

As mentioned above, although the preferable embodiment was shown and demonstrated about the supply machine of this invention, the supply machine which concerns on this invention is not limited only to embodiment mentioned above, A various change implementation is carried out in the scope of the present invention. It goes without saying that it is possible.
For example, in the transfer machine 1, the transfer means 3 provides a transfer / discharge belt 34 between the receiving side and the discharge port side of the receiving space 36, and transfers the received transfer object 101 to the discharge port side. In addition, the conveyance object 101 is discharged using the conveyance / discharge belt 34 and the roller 35, but the configuration is not limited to this.
The transfer means 3a shown in FIG. 4 is a discharge belt comprising a pair of rollers 351 and a belt 352 on the side opposite to the running direction and on the discharge port side of the base plate 31a, instead of the roller 35, with respect to the transfer means 3. 35a and provided, further, in place of the anti-adjacent parallel direction guide plate 32, the counter-travel together direction side of the base plate 31a, it is constituted in which a counter adjacent parallel direction guide plate 32a. In this way, since the belt 352 is rotated by the transport / discharge belt 34, the performance of transporting the transport target 101 to the discharge port side can be improved.
