JP 2003-212338 A JP-A-9-104526

  By the way, in the conveyance device 100 described in Patent Document 1, a relatively long posture changing device 130 for converting the article X from a horizontal posture to a standing posture is required, which increases the size of the entire device and restricts cost and installation space. If there is a problem. Further, on the downstream side of the posture changing device 130, the article X is held in a standing posture by being sandwiched between a pair of fourth and fifth conveyors 134 and 135 whose running surfaces are vertical. When the thickness of the product X varies, or when the packaging material of the packaged product X is different in terms of friction characteristics and flexibility, the standing posture may not be stably maintained.

  On the other hand, in the conveyance device 200 described in Patent Document 2, the article X is converted from a horizontal posture to a standing posture by the rotation of the delivery table 231 of the delivery device 230. There are no problems such as an increase in the size of the device or stability of the posture.

  However, when the supplied article X is received by the delivery table 231 of the delivery device 230, the positional deviation of the article X that has arrived at the delivery table 230 is caused by variations in the entry direction of the article X, the position of the center of gravity, the inclination, and the like. In such a case, the article X cannot be delivered to the holding device 210 at the subsequent stage in an appropriate positional relationship, and as a result of the accumulation posture of the delivered articles X... X being disturbed, the article X accumulated at the discharge position. ... There is a problem that X cannot be discharged smoothly.

  Accordingly, an object of the present invention is to provide a transport device that can position and receive articles at a receiving position and that does not disturb the stacking posture.

  In order to solve the above problems, the present invention is configured as follows.

  In the first aspect of the invention, a delivery means for receiving an article supplied from the outside at a predetermined receiving position and delivering it to the downstream side, and a plurality of articles delivered from the delivery means are integrated in the front-rear direction. A transfer apparatus having a holding means for holding the holding means and a transfer means for transferring the holding means to a discharge position, wherein the delivery means stands up by receiving articles one by one in a predetermined receiving posture at the receiving position. The article is raised by rotating in a posture direction, and has a delivery table for delivering the article to the holding means, and the delivery table has a slightly different receiving posture from a horizontal posture to a counter-rotating direction. It is configured to have an inclined posture, and a movement restricting member that restricts the movement of the accepted article is provided on the side that is lowered by the inclination.

  The invention according to claim 2 is the transfer device according to claim 1, further comprising a carry-in means for carrying the article into the receiving position, wherein the carrying surface of the carry-in means is a surface of the delivery table. It is characterized in that it is inclined substantially in accordance with the receiving posture.

  First, according to the first aspect of the present invention, when the delivery table receives an article supplied from the outside at the receiving position, the delivery table rotates in the standing posture direction, and accordingly, the article is placed in the standing posture. And since the delivery stand delivers the received article to the holding means, the article is held by the holding means in a stacked state in a standing posture. Therefore, it is not necessary to provide a relatively long posture changing device for changing the article from the horizontal posture to the standing posture as in the conventional case, and the entire device does not increase in size.

  Furthermore, unlike the conventional posture changing device, it is not a standing posture that is sandwiched between a pair of conveyors whose running surfaces are vertical at the downstream end, for example, when the thickness varies with the same type of packaged article, or Even when the packaging material of the packaged article is different in terms of friction characteristics and flexibility, the article can be stably raised without being affected by these.

  In addition, since the delivery table accepts the article in a posture slightly inclined from the horizontal posture to the counter-rotating direction at the time of receiving the article, the accepted article moves in the inclined direction on the delivery table and is moved by the movement restricting member. Movement will be restricted. Therefore, it is possible to realize a transport apparatus that can position and receive articles at the receiving position and that does not disturb the stacking posture.

  According to the second aspect of the present invention, the conveyance surface of the carrying means on the article supply side and the delivery table on the article receiving side are substantially coincident and inclined, so that there is no difference between the carrying means and the delivery table. Goods exchange will be smooth. Moreover, since the posture of the article is inclined before entering the delivery table, the effect of inclining the delivery table is further promoted.

  The best mode for carrying out the present invention will be described.

  The conveyance device 1 according to the embodiment of the present invention shown in FIGS. 1 and 2 conveys a relatively flat packaged article X such as a snack, and the articles X are indicated by arrows a in order from the upstream side. The delivery conveyor 11 that carries in the delivery position P1, the delivery device 12 that receives the article X from the delivery conveyor 11 and delivers it to the downstream side, and the articles X... X that are delivered from the delivery device 12 in an accumulated state. As shown by b, it has a stacking and conveying apparatus 13 that conveys it to the discharging position P2, and a discharging apparatus 14 that discharges a group of articles X ... X conveyed to the discharging position P2.

As a result, the driving force of the motor 29 is transmitted to the outer support plate 21, and the support plate 21 rotates once in the direction of the arrow c around the fixed shaft 22, that is, the central toothed pulley 25, due to the aforementioned number of teeth. In the meantime, the four toothed pulleys 26... 26, that is, the rotary shafts 23... 23 rotate twice in the direction of the arrow d via the toothed timing belt 28.

  That is, when the motor 29 is driven, the delivery tables 24... 24 fixed to the rotary shafts 23... 23 rotate in the direction of the arrow d to realize the above-described predetermined receiving posture and standing posture, and support. The plate 21 moves forward, that is, in the direction of the arrow b through the rotation in the direction of the arrow c. When the support plate 21 rotates once in the direction of the arrow c, the delivery tables 24... 24 return to their original positions and postures again.

  As shown in FIGS. 3 and 4, the delivery table 24 that receives the article X supplied from the direction of the arrow a and transfers it in the direction of the arrow b orthogonal to the supply direction a includes the mounting surface 24 a and the mounting table 24 a.

At this time, the transfer table 24 _2, which is shaped to not interfere with each other as described above and the lower guide member 62 intersect.

In addition, the empty bucket 44 that has left the discharge position P2 overlaps the upstream side of the bucket 45 that is receiving the articles within a predetermined range, and is determined by the partition members 51 and 51 of both buckets 44 and 45. A space for holding the ₁₂ articles X _{1 to} X ₁₂ is defined. After the overlap, both buckets 44 and 45 move in synchronization. Then, by the operation of the air cylinder 73 of the upper guide mechanism 71, the pressing member 72 is pressed down an upper end of such article X ₅ is moved upward as indicated by an arrow e '.

Next, as shown in FIG. 15, both buckets 44 and 45 move in the arrow b direction by one article while being synchronized. Transfer table 24 ₂ is further rotated in the arrow d direction, with passes to the bucket 45 the articles _{X 6} from the lower guide member 62, lapping in a standing posture behind the article _X 1 to X ₅ in the bucket 45. Meanwhile, the transfer table 24 ₃ a subsequent, as well as reach the receiving position P1, which is a predetermined receiving position, the receiving Dodai 24 _3, and a new article X ₇ is supplied.

As described above, the delivery device 12 is provided with the _four delivery tables 24 _{1 to} 24 _4, which are replaced and can receive the article X from the upstream side, thereby speeding up the accumulation process at the delivery position P 1. .

  With the configuration described above, the delivery table 24 rotates in the standing posture direction when receiving the flat article X supplied from the outside at the receiving position P1, and accordingly, the article X is placed in the standing posture. The And since the delivery stand 24 delivers the received articles X in the buckets 44 and 45 while being packed in order from the front side, the articles X... X are held in a standing posture by the buckets 44 and 45. Therefore, it is not necessary to provide a relatively long posture changing device for shifting the article X from a horizontal posture to a standing posture as in the conventional case, and the entire device does not increase in size.

  Furthermore, unlike the conventional posture changing device, it is not a standing posture that is sandwiched between a pair of conveyors whose running surfaces are vertical at the downstream end, for example, when the thickness varies with the same type of packaged article, or Even when the packaging material of the packaged article is different in terms of friction characteristics and flexibility, the article can be stably raised without being affected by these.

  In addition, since the delivery table 24 accepts the article X in a posture slightly inclined from the horizontal posture to the counter-rotating direction d ′ when the article is received, the received article X moves on the delivery table 24 in the inclined direction. Thus, the movement is restricted by the movement restriction wall 24c. Therefore, the conveyance device 1 that can position and receive the article X at the receiving position P1 and does not disturb the stacking posture is realized.

  Since the conveying surface of the carry-in conveyor 11 on the article supply side and the delivery table 24 on the article receiving side are substantially coincident and inclined, the delivery of articles between the carry-in conveyor 11 and the delivery table 24 becomes smooth. Moreover, since the posture of the article X is inclined before entering the delivery table 24, the effect of inclining the delivery table 24 described above is further promoted.

  It should be noted that the present invention is not limited to the above-described embodiment that has been specifically described in detail, and may be any that are within the spirit of the present invention. For example, the inclination angles α, β, and γ are not shown by using specific numbers, but are set in a range in which the article X is stably conveyed and delivered. In particular, the angles β and γ may be zero.

  The stacking and conveying device 13 is provided with a pair of flat belts 43 and 43 and buckets 44 and 45, which can be added respectively.

  As described above, according to the present invention, it is possible to provide a transport apparatus that can position and receive articles at the receiving position and that does not disturb the stacking posture. That is, the present invention is widely suitable for the technical field of article conveyance.
