Description

Technical Field

[0001] The utility model relates to the technical field of intelligent warehousing systems, and in particular to a long material stacker capable of crossing lanes. Background Art

[0002] Stacker cranes are the core storage and retrieval equipment in intelligent warehousing systems and are widely used in various industries.

[0003] The intelligent storage multi-aisle system for long materials currently adopts the form of one stacker in one aisle, but this method requires a large investment for a three-dimensional warehouse with a small footprint. When you want to share one stacker in multiple aisles, you can install a transfer device to make the stacker turn and complete the aisle conversion. However, for the long material stacker, the overall length of the stacker is long, which requires a larger space for installing the transfer device to ensure that the long material stacker has a sufficient turning radius to complete the aisle conversion. This is a huge waste of space utilization.

[0004] A bridge stacker can also be used, but in order to complete the lane conversion action, the bridge stacker must first lift the long material from the lowest position to above the highest position of the stereoscopic warehouse through the lifting mechanism. At the highest point of the equipment, the long material is driven by the transverse mechanism to move horizontally to the target lane. Since the stacker has an extra step of lifting the long material each time it takes and puts the long material, it has a great impact on the overall rhythm of the stacker's material taking and feeding. In addition, due to the transverse mechanism and track of the bridge stacker, it needs to be raised to the top of the stereoscopic warehouse by a column bracket. The overall investment of the equipment is large, and the high height of the equipment is not conducive to the stability of the overall operation of the equipment, and it is inconvenient to repair.

Among them, the lowest position of the cargo platform relative to the stacker frame is lower than the lowest point of each suspension unit, and the width of the stacker frame is greater than the width of each suspension unit, so that the stacker frame can be driven by the walking mechanism to cross the corresponding number of suspension units from the lane where it is located and then run to the required lane.

[0010] Furthermore, the vertical lifting mechanism includes a sliding frame slidably connected to each column and a driving device connected to the sliding frame. The sliding frame is fixedly connected to the cargo platform, and the driving device is used to provide lifting power for the sliding frame.

[0011] Furthermore, a pulley assembly is connected to the top of the column, and the driving device is a winch fixed on the outside of the column. The free end of the rope of the winch is fixedly connected to the sliding frame after passing through the pulley assembly.

[0012] Furthermore, the driving device is a hydraulic cylinder fixed between the bottom beam and the lifting platform, and the driving end of the hydraulic cylinder is connected to the lifting platform.

[0013] Furthermore, a stopper component is formed at the top end of the column to prevent the sliding frame from falling out.

[0014] Furthermore, a plurality of suspension units arranged at intervals in the transverse direction form a group of transverse arrangement units, and each group of transverse arrangement units is used in conjunction with a long material stacker capable of crossing the aisle.

[0015] Furthermore, the height of the column is lower than the bottom surface of the top beam of the suspension rack, and the highest position of the cargo platform relative to the column is higher than the position of the uppermost storage position of the suspension rack.

[0016] The utility model has a simple structure for the long material stacker that can cross the aisle, and the manufacturing and installation are more convenient. The equipment is reliable to use and the investment is small. It is particularly suitable for a three-dimensional storage system for rows of long materials in a small space.

Figure 2 As shown, the long material stacker 100 that can cross the aisle is used for a suspended shelf 200, and the suspended shelf 200 includes a plurality of suspension units 201 arranged at intervals in a transverse direction, and aisles 202 are formed between adjacent suspension units 201. Figure 1 and Figure 2As shown, the long material stacker 100 that can cross the aisle may include: a stacker frame 1, the stacker frame 1 includes two parallel columns 11 and a bottom beam 12 connected between the two columns 11; a walking mechanism 2 connected to the bottom end of the bottom beam 12; a vertical lifting mechanism 3 connected to the columns 11; a cargo platform 4 connected to the vertical lifting mechanism 3, the vertical lifting mechanism 3 is used to drive the cargo platform 4 to move vertically up and down; and a telescopic fork group 5 connected to the cargo platform 4, the telescopic fork group 5 is used to horizontally extend and retract relative to the cargo platform 4 to achieve material retrieval or delivery. Among them, the lowest position of the cargo platform 4 relative to the stacker frame 1 is lower than the lowest point of each suspension unit 201, and the width of the stacker frame 1 is greater than the width of each suspension unit 201 (i.e. Figure 2 The width in the direction perpendicular to the paper surface as shown) is large enough to enable the stacker frame 1 to be driven by the traveling mechanism 2 to move from the lane 202 where it is located to the desired lane 202 after traversing a corresponding number of suspension units 201 transversely.

[0021] When the cross-aisle long material stacker 100 of the utility model is working, when the storage position of the long material row 300 and the material picking position are in the same aisle 202, the specific implementation method of the long material row 300 entering the warehouse is as follows: first, the loading platform 4 on the stacker frame 1 is in a low position waiting for receiving materials. When the long material row 300 reaches the material picking and feeding position, the telescopic fork group 5 on the loading platform 4 extends an empty fork to the incoming material side, the loading platform 4 rises, and the telescopic fork group 5 is retracted to take the long material row 300 to the loading platform 4. Then, the loading platform 4 rises with the material to the specified material position of the three-dimensional shelf 200, and the telescopic fork group 5 extends the material. The cargo platform 4 descends, and the empty forks of the telescopic fork group 5 are retracted, completing the warehousing operation of the long material row 300; the specific implementation method of the long material row 300 out of the warehouse is as follows: first, the cargo platform 4 on the stacker frame 1 reaches the specified material position, the telescopic fork group 5 on the cargo platform 6 extends the empty forks toward the specified material position side, the cargo platform 4 rises, the telescopic fork group 5 is retracted, and the long material row 300 is taken to the stacker, and then the cargo platform 4 descends, and the long material row 300 is delivered to the pick-up and delivery position, the telescopic fork group 5 extends the material, the cargo platform 4 descends, and the empty forks of the telescopic fork group 5 are retracted, completing the out-of-warehouse operation of the long material row 300.

[0022] When the designated storage position and the picking position of the long material row 300 are not in the same lane 202, the specific implementation method of the long material row 300 entering the warehouse is as follows: first, the loading platform 4 on the stacker frame 1 is at a low position waiting to receive materials. When the long material row 300 reaches the picking and feeding position, the telescopic fork group 5 on the loading platform 4 extends an empty fork toward the incoming material side, the loading platform 4 rises, and the telescopic fork group 5 is retracted to take the long material row 300 to the loading platform 4. The loading platform 4 with the material drops to the lowest position. At this time, the highest position of the loading platform 4 with the material is still lower than the lowest point of the suspension unit 201. When the stacker frame 1 moves across the lane 202, the loading platform 4 can pass through the bottom of the suspension unit 201 with the material. When the stacker frame 1 reaches the designated lane 202, the loading platform 4 rises to the designated material position of the corresponding suspension unit 201, the telescopic fork group 5 extends out with the material, and the loading platform 4 descends, the empty forks of the telescopic fork group 5 are retracted, and the warehousing operation of the long material row 300 is completed; the specific implementation method of the long material row 300 out of the warehouse is as follows: first, the loading platform 4 on the stacker frame 1 reaches the specified material position, the telescopic fork group 5 on the loading platform 4 extends the empty fork to the specified material position side, the loading platform 4 rises, the telescopic fork group 5 is retracted, the long material row 300 is taken to the loading platform 4, and then the loading platform 4 descends to the lowest position. At this time, the highest position of the loading platform 4 with materials is still lower than the lowest point of the suspension unit 201. When the stacker frame 1 moves across the lane 202, the loading platform 4 can pass through the bottom of the suspension unit 201 with materials. When the stacker frame 1 reaches the material retrieving lane, the loading platform 4 rises to the material picking and feeding position, the telescopic fork group 5 extends the materials, the loading platform 4 descends, and the empty forks of the telescopic fork group 5 are retracted, and the out-of-warehouse operation of the long material row 300 is completed.

[0023] The utility model has a simple structure for the long material stacker 100 that can cross the aisle, and the manufacturing and installation are more convenient. The equipment is reliable to use and the investment is small. It is particularly suitable for a three-dimensional storage system for rows of long materials in a small space. It can effectively solve the problems of too much space occupied by the switching when the long material stacker changes the aisle, low storage rhythm efficiency, poor stability, inconvenient maintenance and excessive investment when the bridge-type long material stacker runs on an elevated frame, thereby promoting the application of intelligent storage systems in the field of long material storage and is conducive to popularization and application.

[0024] In a preferred embodiment, the telescopic fork set 5 can be a bidirectional telescopic fork set, so that when the stacker frame 1 is located in the lane 202, it can pick up or deliver materials to the two adjacent suspension units 201, which can further improve the storage rhythm and efficiency. Preferably, the bidirectional telescopic fork set can be linked, can act in groups, or can act individually.

[0025] According to the utility model, the hanging shelf 200 may also include a longitudinal (i.e., along Figure 2The plurality of suspension units 201 are arranged at intervals (in the direction perpendicular to the paper surface shown), and each suspension unit 201 is distributed in a rectangular array. The walking mechanism 2 is also used to drive the stacker frame 1 to walk longitudinally along the same lane 201, so that the stacker frame 1 can feed or retrieve materials to the suspension units 201 arranged longitudinally. Such a setting method can further realize that the long material stacker 100 that can cross the lane can feed and retrieve materials across the lane, and can further realize that the long material stacker 100 that can cross the lane can feed and retrieve materials to different suspension units 201 in the same lane 202, so that one long material stacker 100 that can cross the lane can complete the feeding and retrieving operations of each suspension unit 201 of the entire suspension shelf 200.

[0026] Preferably, the long material stacker 100 that can cross the lanes may also include a track assembly 6 laid on the ground for slidingly cooperating with the traveling mechanism, and the track assembly 6 may include a first guide rail (not shown in the figure) for making the traveling mechanism 2 walk horizontally to realize walking across the lanes and a second guide rail (not shown in the figure) for making the traveling mechanism walk longitudinally to realize walking along the same lane, and the first guide rail is perpendicular to and connected to the second guide rail. In other words, the first track and the second track are in a cross shape. Through this setting, when the traveling mechanism needs to change from the first guide rail to the second guide rail, the direction of the pulley of the traveling mechanism can be changed at the connection point between the first guide rail and the second guide rail, so that the traveling mechanism 2 can be changed from walking horizontally to walking longitudinally.

[0027] According to the utility model, if Figure 1 As shown, the vertical lifting mechanism 3 may include a sliding frame 31 slidably connected to each column 11 and a driving device 32 connected to the sliding frame 31 , the sliding frame 31 is fixedly connected to the cargo platform 4 , and the driving device 32 is used to provide lifting power for the sliding frame 31 .

[0028] In a preferred embodiment, Figure 1 As shown, the top of the column 11 may be connected to a pulley assembly 33 , and the driving device 32 may be a winch fixed on the outside of the column 11 , and the free end of the rope of the winch is fixedly connected to the sliding frame 31 after passing through the pulley assembly 32 .

[0029] In another preferred embodiment, the driving device 32 may also be a hydraulic cylinder (not shown) fixed between the bottom beam 12 and the lifting platform 4, and the driving end of the hydraulic cylinder is connected to the lifting platform 4. Preferably, in this embodiment, a stopper member for preventing the sliding frame 31 from falling out may be formed at the top end of the column 11.

[0030] According to the utility model, a plurality of suspension units 201 arranged at intervals in the transverse direction form a group of transverse arrangement units, and each group of transverse arrangement units cooperates with a stacker 100 for long materials across the aisles. This embodiment enables each stacker 100 for long materials across the aisles to perform feeding and retrieving operations only on each suspension unit 201 in a group of transverse arrangement units. Such a setting can reduce the time for feeding and retrieving materials for the entire suspension shelf 200, and also facilitates more targeted control of the stacker 100 for long materials across the aisles corresponding to each group of transverse arrangement units.

[0031] In such Figure 1 and Figure 2 In the preferred embodiment shown, the height of the column 11 is lower than the bottom surface of the top beam 203 of the overhead shelf 200, and the highest position of the cargo platform 4 relative to the column 11 is higher than the position of the top storage level 210 of the overhead shelf 200. By setting the height of the column 11 to be lower than the bottom surface of the top beam 203 of the overhead shelf 200, when the long material stacker 100 that can cross the aisle is walking in the aisle, the top of the column 11 will not be blocked; by setting the highest position of the cargo platform 4 relative to the column 11 to be higher than the position of the top storage level 210 of the overhead shelf 200, the cargo platform 4 can deliver the long row of materials 300 to the top storage level 210 of the overhead shelf 200.
