  Then, the transport device 13 operates so as to perform the receiving process of the incoming product A and the outgoing process of the outgoing product B in parallel.

  First, with reference to FIG. 7 to FIG. 10, the processing operation of the incoming product A and the outgoing product B in the ascending transport unit 26 will be described.

  The ascending transport unit 26 includes a plurality of transport platform detection sensors P1-1 that detect the position of the ascending transport platform 37 corresponding to each position of the first delivery unit 32 and the plurality of second delivery units 33. , P1-2 ..., a plurality of transport object detection sensors P2-1, P2-2 ... for detecting the position of the incoming transported object 12, and a plurality of stops for detecting the stop position of the incoming transported object 12. Sensors P3-1, P3-2 ... are installed.

  As shown in FIG. 7 (a), for example, the goods A1 are loaded into the first loading section 21, the goods B1 are loaded into the second loading section 22 at the bottom, and the second loading from the second level from the bottom. The outgoing article B2 has been carried into the unit 22. Further, the transport table 37 immediately before the transport table 37 on which the goods A1 are to be loaded is in a state of passing upward through the first delivery unit 32. Then, it is assumed that the outgoing order of the outgoing product B1 and the outgoing product B2 is set in the order of the outgoing product B1 and the outgoing product B2.

  As shown in FIG. 7 (b), when the immediately preceding transport table 37 rises to a position where it does not interfere with the incoming goods A1 sent onto the first delivery section 32, the immediately preceding transport table 37 is detected. Sensor P1-1 detects. Based on the detection of the conveyance table detection sensor P1-1, the first delivery roller 58 of the first delivery section 32 is driven to rotate, and the delivery of the goods A1 from the first delivery section 21 to the first delivery section 32 is performed. Start.

  As shown in FIG. 7 (c), after the carrier detection sensor P1-1 detects the passage of the immediately preceding carrier 37, the lowermost second receiving unit is moved toward the approach position in the ascending transport unit 26. The movement of the second transfer roller 65 of the transfer section 33 is started.

  As shown in FIG. 7D, the first delivery unit 32 conveys the goods A1 received from the first carry-in unit 21 to a position where the goods A1 are delivered to the other mounting position 40b of the carrier 37. Incoming goods A2 to be stored next are carried into the first carrying-in section 21.

  The second delivery roller 65 of the lowermost second delivery section 33 enters the ascending transport section 26. When the immediately preceding carrier 37 rises to a position where it does not interfere with the outgoing goods B1 sent onto the lowermost second delivery section 33, the carrier carrier sensor P1-2 detects the immediately preceding carrier 37. I do. The second delivery roller 65 of the lowermost second delivery unit 33 is rotationally driven based on the detection of the transfer table detection sensor P1-2, and the lowermost second delivery unit is moved from the lowermost second loading unit 22 to the lowermost second delivery unit. The delivery of goods B1 to 33 is started.

  As shown in FIG. 7 (e), after the conveyed goods detection sensor P2-1 detects the passing of the goods A1 conveyed by the first delivery unit 32, and then the stop sensor P3-1 detects the goods A1 received. Then, the transport of the goods A1 received by the first delivery unit 32 is stopped (the rotation of the first delivery roller 58 is stopped). Thereby, the goods A1 on the first delivery unit 32 are arranged at a position where the goods A1 are delivered to the other-side mounting position 40b of the carrier 37.

  As shown in FIG. 8 (a), the second delivery unit 33 at the lowermost stage moves the outgoing goods B1 received from the second carry-in unit 22 to a position where the goods B1 are delivered to the one-side mounting position 40a of the carrier 37. That is, the sheet is conveyed from the other-side delivery section 33b to the one-side delivery section 33a.

  As shown in FIG. 8 (b), the outgoing goods B1 conveyed by the second delivery section 33 at the lowermost stage transfer from the other-side delivery section 33b to the one-side delivery section 33a, and the passing of the outgoing goods B1 is used for detecting the conveyed article. When the sensor P2-2 detects, the second delivery roller 65 of the other delivery part 33b is stopped from rotating, and the other delivery part 33b is retracted from the inside of the ascending transport part 26. At this time, by using a high-speed drive cylinder as the cylinder 71, the other-side delivery section 33b is moved away from the inside of the ascending transport section 26 at a high speed by using the high-speed driving cylinder for the other-side delivery section 33b of the lowermost second delivery section 33. . This is because the incoming goods A1 on the first delivery section 32 located immediately below the other-side delivery section 33b are lifted by the carrier 37, so that the interference between the other-side delivery section 33b and the received articles A1 is ensured. In order to prevent this.

  When the stop sensor P3-2 detects the outgoing product B1 conveyed by the one-side delivery section 33a of the lowermost second delivery section 33, the conveyance of the outgoing article B1 by the one-side delivery section 33a is stopped (the second delivery roller). Stop rotation of 65). As a result, the outgoing article B1 is arranged on the one-side delivery section 33a at a position where it is delivered to the one-side mounting position 40a of the carrier 37.

  As shown in FIG. 8C, the other delivery unit 33b of the second delivery unit 33 at the lowermost stage completes the evacuation from the ascending transport unit 26 before the incoming product A1 ascends.

  As shown in FIG. 8D, the goods A1 on the first delivery unit 32 are received at the other mounting position 40b of the carrier 37 rising from the lower side of the ascending carrier 26, and the goods are stored by the carrier 37. Raise the product A1.

  As shown in FIG. 8 (e), when the carriage 37 loaded with the goods A1 is moved up to a position where it does not interfere with the goods A2 to be sent next to the first delivery section 32, the conveyance carrying the goods A1 is carried out. The platform 37 is detected by the transport platform detection sensor P1-1. The first delivery roller 58 of the first delivery unit 32 is rotationally driven based on the detection of the conveyance table detection sensor P1-1, and the next delivery item A2 from the first delivery unit 21 to the first delivery unit 32 is received. Start loading.

  Then, as for the incoming articles A2, A3, A4, and so on, the ascending transport section 26 is mounted on the ascending transport table 37 in the same manner as the incoming article A1.

  As shown in FIG. 9 (a), at the one-side mounting position 40a of the carrier 37 on which the goods A1 are mounted, the outgoing goods B1 arranged on the one-side transfer part 33a of the lowermost second transfer part 33 are removed. Receiving and raising the outgoing goods B1 on the transfer table 37. Therefore, the incoming goods A1 and the outgoing goods B1 are mounted together on one carrier 37, and the incoming goods A1 are mounted on the other mounting position 40b of the carrier 37 on the second unloading section 24 side, and the first unloading is performed. The outgoing goods B1 are mounted on one side mounting position 40a of the transfer table 37 on the side of the unit 23.

  As shown in FIG. 9 (b), when the transport platform detection sensor P1-2 detects the transport platform 37 on which the incoming product A1 and the outgoing product B1 are mounted, one side delivery unit 33a of the second delivery unit 33 at the bottom. Is retracted from the inside of the ascending transport section 26.

  As shown in FIG. 9 (c), after the carrier detection sensor P1-2 detects the passage of the carrier 37 on which the incoming product A1 and the outgoing product B1 are mounted, the sensor P1-2 is turned to the entrance position in the ascending transport unit 26. The movement of the second delivery roller 65 of the second delivery unit 33 in the second stage from the bottom is started.

  As shown in FIG. 9D, the second delivery roller 65 of the second delivery unit 33 at the second tier from below enters the ascending transport unit 26. When the carriage 37 on which the incoming product A1 and the outgoing product B1 are mounted is raised to a position where it does not interfere with the outgoing product B2 sent to the second transfer unit 33 from the bottom, the incoming product A1 and the outgoing product B1 are mounted. The transfer table 37 is detected by the transfer table detection sensor P1-3. Based on the detection of the conveyance table detection sensor P1-3, the second delivery roller 65 of the second delivery unit 33 in the second stage from the bottom is driven to rotate, and the second delivery roller 22 in the second stage from the bottom is driven downward. The transfer of the outgoing article B2 to the second delivery unit 33 in the second stage from is started.

  As shown in FIGS. 9E and 10A, the second delivery unit 33 in the second tier from the bottom places the outgoing goods B2 received from the second carry-in unit 22 on one side of the transfer table 37. It is conveyed toward the position to be delivered to 40a, that is, from the other side delivery unit 33b to the one side delivery unit 33a.

  As shown in FIG. 10 (b), the outgoing product B2 conveyed by the second delivery unit 33 at the second stage from the bottom transfers from the other delivery unit 33b to the one-side delivery unit 33a, and the passing of the outgoing product B2 is carried out. When the object detection sensor P2-3 detects, the rotation of the second delivery roller 65 of the other-side delivery unit 33b is stopped, and the other-side delivery unit 33b is retracted from the inside of the ascending transport unit 26.

  When the stop sensor P3-3 detects the outgoing product B2 conveyed by the one-side delivery section 33a of the second delivery section 33 in the second stage from the bottom, the conveyance of the outgoing article B1 by the one-side delivery section 33a is stopped. (2) The delivery roller 65 stops rotating). As a result, the outgoing article B2 is disposed on the one-side delivery section 33a at a position where it is delivered to the one-side mounting position 40a of the carrier 37.

  As shown in FIG. 10C, the other delivery unit 33b of the second delivery unit 33, which is one stage higher than the lowest stage, completes the retreat from the ascending transport unit 26 before the incoming product A2 rises.

  As shown in the order of FIGS. 10 (d) and (e), it is arranged on one side delivery part 33a of the second delivery part 33 of the second stage from the bottom at one side loading position 40a of the carrier 37 on which the goods A2 are loaded. The delivered product B2 is received, and the delivered product B2 is raised by the carrier 37. Therefore, the goods A2 and the goods B2 are loaded together on one carrier 37, and the goods A2 are loaded on the other mounting position 40b of the carrier 37 on the side of the second carrying-out section 24, and the first carrying-out is performed. The outgoing goods B2 are mounted on one side mounting position 40a of the transfer table 37 on the part 23 side.

  Then, the subsequent outgoing products B3,... Are mounted on the ascending transport table 37 in the same manner as the outgoing products B1, B2. For example, the outgoing product B3 is located in the second loading section 22 at the sixth level from the bottom, and is received by the second delivery section 33 at the sixth level from the bottom on the transfer table 37, similarly to the lowest level and the second level from the bottom. hand over.

  It should be noted that the transfer table 37 is not always loaded with the incoming product A and the outgoing product B. When only the incoming product A is installed, when only the outgoing product B is mounted, the incoming product A and the outgoing product are loaded. B may not be mounted.

  Next, FIGS. 11 and 12 explain the processing operation of the incoming product A and the outgoing product B in the descending transport unit 27.

  The descending transport unit 27 includes a plurality of units for detecting the delivery of the transported object 12 to the first unloading unit 23 and the second unloading unit 24 corresponding to the positions of the first sending unit 34 and the second sending unit 35. , And a plurality of carriage detection sensors P5-1, P5-2, P5-3 ... for detecting the position of the descending carriage 37. is set up.

  As shown in FIG. 11A, for example, it is assumed that the incoming goods A1 are set so as to be sorted into the second unloading section 24 at the third tier from the bottom. Even if another incoming product A is mounted on the immediately preceding transport platform 37 that descends prior to the transport platform 37 on which the incoming product A1 is mounted, the incoming product A is the third row from the bottom. When the conveyor 37 is lowered to a height position where it does not interfere with the second sending unit 35, the carrier table sensor P5-3 detects the immediately preceding carrier 37. Based on the detection of the carrier detection sensor P5-3, the second delivery roller 81 of the second delivery unit 35 at the third stage from the bottom enters the descending delivery unit 27, and the second delivery roller 81 is rotationally driven. I do.

  As shown in FIG. 11B, the second sending unit 35 at the third stage from the bottom receives the goods A1 mounted on the other mounting position 40b on the other side of the transporting table 37 descending, and the third stage from the bottom. It is sent out to the second discharge unit 24 of the eye.

  As shown in FIG. 11 (c), an outgoing product B1 is mounted at one side mounting position 40a of the transfer table 37 which has delivered the incoming product A1 to the second unloading section 24 at the third tier from the bottom. The article B1 passes through one side of the second sending section 35 and descends.

  As shown in FIGS. 11D and 11E, when the delivery detection sensor P4-4 detects that the goods A1 have been sent out to the second unloading section 24 at the third row from the bottom, the third row from the bottom is detected. The second delivery unit 35 is retracted from the descending conveyance unit 27 and the second delivery roller 81 is stopped from rotating. When the incoming goods A2 conveyed by the next conveyance table 37 are also sorted into the second unloading section 24 at the third level from the bottom, the second sending section 35 does not have to be retreated.

  As shown in FIGS. 12A and 12B, for example, it is assumed that the incoming goods A2 are set to be sorted into the second unloading section 24 in the second stage from the bottom. Even if another incoming product A is mounted on the immediately preceding transport platform 37 that descends before the transport platform 37 on which the incoming product A2 is mounted, the incoming product A is the second stage from the bottom. When the conveyor 37 is lowered to a height position where it does not interfere with the second sending unit 35, the carrier table sensor P5-2 detects the immediately preceding carrier 37. Based on the detection of the carrier detection sensor P5-2, the second delivery roller 81 of the second delivery unit 35 at the second stage from the bottom enters the descending delivery unit 27, and the second delivery roller 81 is rotationally driven. I do.

  As shown in FIG. 12C, the first delivery unit 34 receives the outgoing goods B1 mounted on the one-side mounting position 40a of the descending carriage 37 and sends it out to the first carry-out unit 23.

  As shown in FIG. 12 (d), it is confirmed that the outgoing article B1 has been sent to the first unloading section 23 based on the detection of the sending detection sensor P4-1.

  As shown in FIG. 12 (e), the second sending unit 35 at the second stage from the bottom receives the goods A2 mounted on the other mounting position 40b on the other side of the transporting table 37 descending, and the second stage from the bottom. It is sent out to the second discharge unit 24 of the eye.

  The other side of the first sending unit 34 in the second direction Y, through which the other side mounting position 40b of the transport table 37 passes, is not normally used for transporting the transported object 12 at normal times. In the event of a failure of the second delivery unit 35 or a failure of the second delivery unit 35, the goods A that are not sent out from the carriage 37 to the second unloading unit 24 and fall down with the carriage 37 occur. The incoming goods A can be received from 40b and sent out to the first unloading section 23.

  .., And outgoing products B2, B3,... Are processed in the same manner as in the incoming product A1 and the outgoing product B1.

  .. Sent to the second unloading section 24 are transferred to the transfer section 17 of the warehouse body 11 and stored in the predetermined storage section 16.

  As described above, in the transport device 13 of the present embodiment, the incoming goods A sent from the first loading portion 21 to the ascending transport portion 26 are sent out from the descending transport portion 27 to the second unloading portion 24 by the transport device body 20. By carrying out the outgoing goods B sent from the second carrying-in section 22 to the ascending carrying section 26 to the first carrying-out section 23 from the descending carrying section 27, the incoming of the incoming goods A and the outgoing of the outgoing goods B are performed in parallel. be able to.

  In other words, according to the transport device 13, one transport device main body 20 transports the transported object 12 (entry A) from one side of the transport device main body 20 to the other side, and one transport device main body 20 receives the transported object 12 from the other side. The transfer of the transfer object 12 (outgoing goods B) to the side can be performed in parallel, and the transfer object 12 can be efficiently transferred in a small space.

  In addition, since the transfer table 37 is provided with a mounting position 40 for mounting the transfer object 12 at two locations on one side and the other side, the transfer object 12 (incoming goods A) that transfers from one side of the transfer device body 20 to the other side is provided. In addition, the conveyed object 12 (outgoing product B) to be conveyed from the other side of the conveying device body 20 to one side can be mounted and conveyed together, and the conveyed object 12 can be conveyed more efficiently.

  Further, at the mounting position 40 on one side of the transfer table 37, the transfer object 12 (outgoing goods B) to be sent from the other side of the transfer device main body 20 to the first unloading section 23 on one side is mounted. At the loading position 40 on the other side of the 37, the transported object 12 (entry A) to be sent from one side of the transporting device body 20 to the second unloading section 24 on the other side is loaded, so that the first unloading from the transport table 37 is performed. The transport of the transported object 12 (outgoing product B) to the unit 23 and the transport of the transported object 12 (incoming product A) from the transport table 37 to the second unloading unit 24 can be performed in parallel.

  Further, the second delivery unit 33 has a one-side delivery unit 33a and another-side delivery unit 33b that can advance and retreat with respect to the ascending transport unit 26, and when the one-side delivery unit 33a and the other-side delivery unit 33b enter. The loading position 40 on one side of a transport table 37 that transports the transported object 12 (outgoing product B) sent from the second loading section 22 to the ascending transport section 26 onto the one-side transfer section 33a and ascends the ascending transport section 26. (The one-side mounting position 40a), and when the other-side transfer part 33b is retracted, the ascending transfer part 26 is moved to the other mounting position 40 (the other-side mounting position 40b) of the carrier 37 that ascends. The loaded transported object 12 (entry A) can be passed.

  Further, a plurality of forks 42 are provided in a comb shape on both sides of the transport table 37 in the first direction X, and the plurality of second delivery rollers 65 of the second delivery section 33 are placed on both sides of the ascending transport section 26 in the first direction X. And a plurality of second delivery rollers 81 of the second delivery unit 35 are moved from both sides in the first direction X of the descending delivery unit 27. , So that the second delivery roller 65 and the second delivery roller 81 have a short stroke for forward and backward movement, and the second delivery roller 65 and the second delivery roller 81 can be moved between the approach position and the retreat position in a short time. Therefore, even if the transport speed of the transported object 12 is increased, the forward / backward switching of the second delivery unit 33 and the second sending unit 35 can be performed, and the transport efficiency of the transport device 13 can be improved.

  In the transport device 13 of the above-described embodiment, the first delivery section 32 receives two received articles A from the first carry-in section 21 and places the two received articles A at two mounting positions 40 on the transport table 37. A may be transferred together, and the second delivery unit 35 may receive two received articles A from the two mounting positions 40 of the carrier 37 and send them out to the second unloading unit 24 together. In this case, similarly to the second delivery unit 33, the second sending unit 35 is divided into two parts in the second direction Y corresponding to the two mounting positions 40 of the carrier 37, and each of the two parts is disposed. What is necessary is just to comprise so that it can advance and retreat with respect to the downward conveyance part 27.

  Similarly, the two delivery items B carried in from the second carry-in unit 22 are received together by the second delivery unit 33, and the two delivery items B are put together at the two mounting positions 40 of the carrier 37. In addition, the first delivery unit 34 may receive two outgoing articles B from the two mounting positions 40 of the transport table 37 and send them out to the first unloading unit 23 together.

  Further, the transfer table 37 may be provided with three or more mounting positions 40 in the second direction Y to transfer a plurality of articles A or a plurality of articles B together.

  The second delivery roller 65 of the second delivery unit 33 capable of moving forward and backward with respect to the ascending transport unit 26 and the second delivery roller 81 of the second delivery unit 35 capable of moving forward and backward with respect to the descending transport unit 27 include: Not limited to the configuration of sliding along the first direction X, the end of the second delivery roller 65 entering the ascending transport unit 26 and the end of the second delivery roller 81 entering the descending transport unit 27 It may be configured to swing up and down.

In this case, the outgoing goods B are mounted on the carrier 37 on which the incoming goods A are not mounted, and are not mounted on the carrier 37 on which the incoming goods A are mounted. In addition, the one-side delivery section 33a and the other-side delivery section 33b of the second delivery section 33 that has delivered the outgoing article B to the transfer table 37 are retreated from the ascending transfer section 26. Then, the outgoing article B is transported from the upward transport section 26 to the downward transport section 27 by the transport table 37.

  As shown in FIGS. 20 (e) to 20 (g), when the length of the outgoing article B in the second direction Y is long, the first sending section 34 arranged on the descending transport section 27 is In addition to 34a, it is provided with another side sending section 34b for assisting the receiving of the outgoing goods B from the carrier 37.

  In FIGS. 20 (e) to (g), the one-side sending portion 34a and the other-side sending portion 34b are fixedly arranged so as to enter the descending transport portion 27, and the one-side sending portion 34a Shows an example in which the first unloading section 23 is arranged. However, the one-side sending unit 34a and the other-side sending unit 34b may be configured to be able to advance and retreat with respect to the inside of the descending transport unit 27 as described above.

  As shown in FIGS. 20 (e) and 20 (f), one delivery unit 34a and the other delivery unit 34b of the first delivery unit 34 receive the outgoing goods B from the transport table 37 descending in the downward transport unit 27. .

  As shown in FIG. 20 (g), the outgoing goods B received on the one side sending part 34a and the other side sending part 34b are sent out to the first unloading part 23.

  If the length of the outgoing product B in the second direction Y is a length that can be received from the carrier 37 by only the one-side sending portion 34a, the other-side sending portion 34b of the reception assistance may not be used. .

  As described above, even if the length of the article B to be delivered in the second direction Y is long, the carrying device 13 can handle the article B as long as the article B can be mounted on the carrier 37.

  Next, FIG. 21 shows a case in which the length of the incoming product A in the second direction Y is long, the length of the outgoing product B in the second direction Y is short, and the incoming product A> the length of the outgoing product B is satisfied. The operation in the case where the incoming goods A and the outgoing goods B can be mounted together on one carrier 37 will be described. In this case, the relationship of (the length of the incoming product A in the second direction Y) + (the length of the outgoing product B in the second direction Y) <(the length of the mounting area of the carrier 37 in the second direction Y) is satisfied. is there. The incoming product A is of a length that can be received from the carrier 37 only by the other side sending section 35b of the second sending section 35, and the second sending section 35 does not use the one side sending section 35a of the reception assistance. . Note that the minimum clearance value may be set so that the incoming product A and the outgoing product B always leave a gap.

  As shown in FIGS. 21 (a) to (d), similarly to FIGS. 19 (a) to (d) described above, in the first delivery unit 32, the ascending transport unit 26 is placed on the ascending transport table 37. Delivery goods A is delivered. The stocked product A is mounted from the other side mounting position 40b of the carrier 37 to a part of the one side mounting position 40a.

  As shown in FIG. 21 (e), the outgoing article B is conveyed onto the other-side delivery section 33b located at the receiving position of the second delivery section 33.

  As shown in FIG. 21 (f), the one-side delivery unit 33a passes through the position of the second delivery unit 33 by the transfer table 37 immediately before the transfer table 37 on which the outgoing goods B is to be mounted. The other-side transfer section 33b is moved into the ascending transport section 26 from the retreat position. In addition, the timing of the approach movement of the one-side delivery unit 33a and the other-side delivery unit 33b is executed based on the detection of each sensor as described above.

  By driving the one-side delivery unit 33a and the other-side delivery unit 33b that have entered the ascending transport unit 26, the outgoing goods B on the other-side delivery unit 33b are transported onto the one-side delivery unit 33a. In this case, in order for the outgoing product B on the other-side delivery section 33b to move onto the one-side delivery section 33a, the one-side delivery section 33a needs to move to the maximum approach position. The tip side of the delivery unit 33a interferes with the goods A on the carrier 37. Therefore, as shown in FIG. 21 (g), the one-side delivery section 33a is moved backward so that the leading end side of the one-side delivery section 33a does not interfere with the goods A on the carrier 37. Further, the retrieval article B is arranged at a predetermined delivery position on the tip side of the one-side delivery section 33a. In addition, the other-side delivery unit 33b that has delivered the outgoing goods B to the one-side delivery unit 33a is retracted from the ascending transport unit 26.

  As shown in FIGS. 21 (h) and 21 (i), the outgoing product B on the second delivery unit 33 is delivered to the transport table 37 which rises in the ascending transport unit 26. The outgoing goods B are mounted on a part of the one-side mounting position 40a adjacent to the incoming goods A already mounted on the carrier 37. Therefore, the incoming product A and the outgoing product B are mounted together on one transport table 37 and transported from the upward transport unit 26 to the downward transport unit 27. In addition, the one-side delivery unit 33a and the other-side delivery unit 33b of the second delivery unit 33 that has delivered the outgoing goods B to the transfer table 37 are retracted from the ascending transfer unit 26.

  Then, in the descending transport section 27, the article A on the transport table 37 is sent out to the second unloading section 24 by the corresponding second sending section 35, and the unloading article B is sent to the first unloading section 23 by the first sending section 34. Will be sent out.

  Thus, even if the length of the incoming product A in the second direction Y is long, the transport device 13 can handle the incoming product A and provide the outgoing product B having a short length in the second direction Y. By combining the goods A and the goods B out on one carrier 37 and carrying them in combination, the carrying efficiency can be improved.

  Next, FIGS. 22 and 23 show that the length of the outgoing product B in the second direction Y is long and the length of the incoming product A in the second direction Y is short. In a certain case, an operation in a case where the incoming goods A and the outgoing goods B are mounted together on one transfer stand 37 will be described. In this case, the relationship of (the length of the incoming product A in the second direction Y) + (the length of the outgoing product B in the second direction Y) <(the length of the mounting area of the (transportation table 37) in the second direction Y) is satisfied. It is in.

  As shown in FIGS. 22 (a) to (d), similarly to FIGS. 19 (a) to (d) described above, in the first delivery section 32, the ascending transport section 26 is placed on the ascending transport table 37. The received goods A are delivered. Stored goods A are mounted on a part of the other side of the carriage 37 at the other side mounting position 40b.

  As shown in FIG. 22 (e), the outgoing article B is transported onto the other delivery part 33b at the receiving position of the second delivery part 33.

  As shown in FIG. 22 (f), the one-side delivery unit 33a passes through the position of the second delivery unit 33 by the transfer table 37 immediately before the transfer table 37 on which the article B is to be loaded. The other-side transfer section 33b is moved into the ascending transport section 26 from the retreat position. In addition, the timing of the approach movement of the one-side delivery unit 33a and the other-side delivery unit 33b is executed based on the detection of each sensor as described above.

  By the driving of the one-side delivery section 33a and the other-side delivery section 33b that have moved into the ascending transport section 26, the outgoing product B on the other-side delivery section 33b is transported onto the one-side delivery section 33a, and the outbound product B is transported. The positioning is stopped at a predetermined delivery position with respect to the carrier 37 with reference to the leading end in the direction. Note that the positioning stop of the article B to be delivered is executed based on the detection of each sensor as described above.

  As shown in FIG. 22 (g), the other-side delivery section 33b is retreated from the ascending transport section 26. When the length of the outgoing product B is such that it extends from the one-side delivery section 33a to the other-side delivery section 33b, the outgoing article B is removed when the other-side delivery section 33b is retracted from the ascending transport section 26. There is a possibility that it will be dragged and displaced. Therefore, when the other-side delivery unit 33b is withdrawn from the ascending transport unit 26, the other-side delivery unit 33b (the second delivery / transport body 111) is withdrawn while being rotated forward, so that the delivery item B is Position shift is prevented. Alternatively, the outgoing article B is once transported from the other-side delivery section 33b to a position where it is placed only on the one-side delivery section 33a, and after the other-side delivery section 33b is retracted, the one-side delivery section 33a (the second delivery carrier 111) ) Is reversed and the outgoing article B is transported to the predetermined delivery position, thereby preventing the outgoing article B from being displaced.

  As shown in FIGS. 22 (h) and (i), the outgoing goods B on the second delivery unit 33 are transferred to the ascending carriage 37 in the ascending conveyor 26. The outgoing goods B are mounted from one side mounting position 40a adjacent to the incoming goods A already mounted on the transfer table 37 to a part near one side of the other side mounting position 40b. Therefore, the incoming product A and the outgoing product B are mounted together on one carrier 37, and are transported from the upward transport unit 26 to the downward transport unit 27. In addition, the one-side delivery section 33a of the second delivery section 33 that has delivered the article B to the carrier 37 returns to the retreat position.

  As shown in FIGS. 23 (a) and 23 (b), in the descending transport section 27, the transport table 37 immediately before the transport table 37 loaded with the incoming goods A to be received passes through the position of the second sending section 35. As a result, the other-side sending section 35b enters and moves into the descending transport section 27. In addition, the timing of the approach movement of the other side sending unit 35b is executed based on the detection of each sensor as described above.

  At this time, if the other-side sending unit 35b is moved to the maximum entry position, the tip side of the other-side sending unit 35b interferes with the outgoing product B on the carrier 37. Therefore, the moving amount L of the other-side sending section 35b entering the lower-side transport section 27 is adjusted so that the other-side sending section 35b does not interfere with the outgoing product B.

  As shown in FIGS. 23 (c) and (d), the incoming article A is received from the transport table 37 descending in the descending transport unit 27 by the other-side sending unit 35b which has moved into the descending transport unit 27.

  As shown in FIG. 23 (e), the other side sending section 35b is retreated from the lower transport section 27. As a result, the other-side sending section 35b returns to the sending position of the articles A to be sent to the second unloading section 24, and the articles A on the other-side sending section 35b are sent out to the second unloading section 24.

  Further, in the descending transport section 27, the outgoing goods B on the transport table 37 are sent out to the first unloading section 23 by the first sending section 34.

  As described above, even when the length of the outgoing product B in the second direction Y is long, the transport device 13 can handle the outgoing product B, and the incoming device A having the short length in the second direction Y can be used. By combining the goods A and the goods B out on one carrier 37 and carrying them in combination, the carrying efficiency can be improved.

  In the transport device 13 according to the second embodiment, as in the first embodiment, one transport device main body 20 allows the transported object 12 (incoming goods) from one side of the transport device main body 20 to the other side. A) and the transfer of the transfer object 12 (outgoing goods B) from the other side of the transfer device body 20 to one side can be performed in parallel, and the transfer object 12 can be efficiently transferred in a small space. And the like.

  Further, since each of the delivery units 32 and 33 and each of the delivery units 34 and 35 advance and retreat in the second direction Y with respect to the ascending transport unit 26 and the descending transport unit 27, each of the delivery units in the first direction X. There is no need to provide a retreat space for the 32, 33 and each of the sending sections 34, 35, and the distance between the ascending transport section 26 and the descending transport section 27 of the transport device main body 20 can be reduced and the size can be reduced. Moreover, it is possible to cope with the automatic warehouse system 10 in which the intervals between the two rows of storage units 16 are narrow.

  In addition, since the moving direction of each of the transfer units 32 and 33 and each of the sending units 34 and 35 is the same as the direction of conveyance of the conveyed object 12, the transfer unit 32 transports the goods on the transfer units 32 and 33 and the sending units 34 and 35. It is possible to move while the object 12 is placed thereon, and the transfer efficiency of the transfer device 13 can be improved.

  That is, in each of the delivery units 32 and 33, the one-side delivery unit 32a or the other-side delivery unit 33b enters the ascending transport unit 26, and moves on the one-side delivery unit 32a or the other-side delivery unit 33b. Since the entering and moving of the conveyed goods 12 can be performed at the same time, the conveyed goods 12 are placed on the one-side transferring part 32a or the other-side transferring part 33b after the one-side transferring part 32a or the other-side transferring part 33b moves in. The transported object 12 can be promptly arranged at a predetermined position of the ascending transport section 26 as compared with the case of feeding. Therefore, even if the transfer speed of the transfer object 12 by the transfer table 37 is increased, each of the delivery units 32 and 33 can cope, and the transfer efficiency of the transfer device 13 can be improved.

  Similarly, in each of the sending units 34 and 35, the one-side sending unit 34a or the other-side sending unit 35b is retracted with respect to the descending transport unit 27, and is received on the one-side sending unit 34a or the other-side sending unit 35b. Can be performed simultaneously with the retreat movement of the conveyed object 12, so that when the conveyed object 12 is sent out from the one side sending part 34a or the other side sending part 35b, the one side sending part 34a or the other side sending part 35b is retreated. In comparison, the retreat movement timing of the one-side sending unit 34a or the other-side sending unit 35b can be advanced. Therefore, even if the transfer speed of the transfer object 12 by the transfer table 37 is increased, each of the sending units 34 and 35 can respond, and the transfer efficiency of the transfer device 13 can be improved.

  Further, in each of the transfer units 32 and 33, immediately after passing the transfer table 37 immediately before the transfer table 37 for transferring the conveyed article 12, the other-side transfer unit 32b or the one-side transfer unit 33a is moved to the inside of the ascending transfer unit 26. If the one-side delivery part 32a or the other-side delivery part 33b on which the article 12 is placed moves into the ascending transport part 26, the one-side delivery part 32a or the other-side delivery part 33b immediately moves from the one-side delivery part 32a or the other-side delivery part 33b. The article 12 can be transported to the delivery section 32b or the one-side delivery section 33a. Therefore, even if the transfer speed of the transfer object 12 by the transfer table 37 is increased, each of the delivery units 32 and 33 can cope, and the transfer efficiency of the transfer device 13 can be improved.
