Description
Technical Field
The invention belongs to the field of stackers, and particularly relates to a cargo carrying platform and a stacker.
Background
The track tunnel stacking crane is core equipment in an automatic warehouse logistics system and is mainly used for carrying operation of goods in and out of a goods shelf. The rail tunnel stacking crane generally realizes the horizontal movement of the whole stacking machine on a fixed rail through a traveling gear motor and traveling wheels; the lifting speed reducing motor, the winding drum and the steel wire rope drive the loading platform to do high-speed vertical lifting movement. After the goods are conveyed by the rail tunnel stacker crane and lifted to the appointed layer of the appointed column of the goods shelf, the rail tunnel stacker crane enables the goods to be transferred to the appointed position through the goods fork and the goods fork driving mechanism. The traditional track tunnel stacking crane can only access one cargo unit when carrying out cargo access operation once, and the cargo access efficiency is lower. When the storage area of the stereoscopic warehouse is longer in roadway length and larger in area, the rail roadway stacking crane which can only access one cargo at a time can cause low comprehensive warehouse entering and exiting efficiency of the automatic stereoscopic warehouse.
Chinese patent publication No. CN113753805B discloses a palletizing apparatus including a loading rack having a plurality of cargo spaces. The carrying shelf is provided with a carrying platform capable of horizontally moving, and the carrying platform is provided with a telescopic fork. The goods on the goods shelves can be taken onto the appointed goods places of the goods shelves by the goods platforms and the telescopic forks one by one, and the goods on the goods places of the goods shelves are placed onto the appointed positions of the appointed goods shelves one by one. Thus, a palletizer apparatus for accessing loads by movement of a single load bed, while capable of handling multiple loads at a time, must have an empty load path between loads accessed at a time. That is, after the goods are stored and taken out, the goods carrying platform and the telescopic fork thereon must travel to the next goods location in an empty state to be stored and taken out next time, and the time for carrying the goods by the stacking device is prolonged. Therefore, the overall stacking efficiency of the stacking equipment is low, and the comprehensive warehouse-in and warehouse-out efficiency of the automatic stereoscopic warehouse is not improved.

Detailed Description
The features and capabilities of the present invention are described in further detail below in connection with the examples.
The scheme principle of the stacker is as follows:
A stacker, the structure of which can be seen in fig. 1, comprises a loading platform 5, and the loading platform 5 is provided with side-by-side goods spaces. Conveying mechanisms are arranged on the goods spaces side by side and used for realizing the transfer of goods between the goods spaces. 2-4, at least one of the cargo positions is independently provided with a lifting telescoping fork for removing cargo from and placing cargo on its cargo position onto the pallet. When the stacker disclosed by the invention executes the delivery of cargoes, the cargo space with the lifting telescopic fork transfers cargoes from the goods shelf to the cargo space through the lifting telescopic fork, and then the cargo is transferred to other cargo spaces by utilizing the conveying mechanism of the cargo space, so that the next cargo taking is performed by freeing the cargo space, and the stacker can realize the function of positioning for multiple cargo taking at one time, so that the cargo taking efficiency of the stacker is improved. During warehouse entry, the conveying mechanism of other goods places shifts the goods to the goods place of taking the flexible fork of lift on to place the goods on the goods shelves through the flexible fork of lift on this goods place, and then make the stacker can realize once locating the function of multiple stock to improve the stock efficiency of stacker.
When the stacker performs the work of storing and taking out goods, no idle stroke of the conveying mechanism and the lifting telescopic fork on the goods space can occur; the movement of the conveying mechanism and the movement of the lifting telescopic fork are independent of each other, so that the conveying mechanism which does not interfere with the lifting telescopic fork can still independently convey goods when the lifting telescopic fork performs goods storing and taking operation, and the goods storing and taking efficiency is improved; when the goods move to a position where the goods do not interfere with the lifting telescopic fork, the lifting telescopic fork can perform goods picking operation again, so that the time interval between single goods picking operations is reduced. Therefore, the structure can avoid the empty load travel of the goods space of the stacker in the running process, and effectively improve the goods storage and taking efficiency of the stacker.
Based on the principle of the above scheme, the embodiment 1 of the stacker of the present invention is:
A stacker, the structure of which can be seen with reference to figure 1, comprises an upper beam assembly 1, a lower beam assembly 2 and a metal upright 3 fixedly connected between the upper beam assembly 1 and the lower beam assembly 2. The upper beam assembly 1, the lower beam assembly 2 and the metal upright posts 3 form a frame body of the stacker together. The lower beam assembly 2 includes a travelling mechanism 4 to allow the stacker to travel on a fixed track.
The metal upright post 3 is provided with a lifting guide rail, and a cargo platform 5 is assembled on the lifting guide rail in a guiding way. A lifting assembly 6 is mounted on the outside of the metal upright 3 to lift or drop the cargo platform 5 via a wire rope 7. The cargo platform 5 is constructed as shown with reference to fig. 2-4, with side-by-side cargo spaces provided thereon, and with a conveyor mechanism provided on each cargo space. At least one of the side-by-side cargo bays is independently provided with a lifting telescopic fork for removing cargo from its cargo bay to the shelf and for placing cargo on the shelf to its cargo bay. For a goods space with a lifting telescopic fork, the conveying mechanisms are arranged on two sides of the goods space facing to the goods shelf in pairs; the lifting telescopic fork is arranged at the center of the goods space. The goods are placed on the conveying mechanism, so that the stacker can transfer the goods taken by the lifting telescopic fork to other goods places through the conveying mechanism, and the goods on other goods places to the goods places with the lifting telescopic fork. When goods go out of the warehouse, the goods space with the lifting telescopic fork transfers the goods from the goods shelf to the conveying mechanism of the goods space through the lifting telescopic fork, and then the goods are transferred to the conveying mechanism of other goods spaces through the conveying mechanism on the goods space, so that the goods space with the lifting telescopic fork is emptied to take the goods next time, and then the stacker can realize the function of positioning the goods for multiple times, so that the goods taking efficiency of the stacker is improved. When the goods are put in storage, the conveying mechanism on other goods places transfers the goods to the conveying mechanism on the goods place with the lifting telescopic fork, and then the goods are placed on the goods shelf through the lifting telescopic fork, so that the stacker can realize the function of positioning multiple stock at one time, and the stock efficiency of the stacker is improved.
Through the electric drive system and the electric control system matched with the stacker structure, the stacker can realize the goods transfer from the stereoscopic goods shelf storage area to the front conveyor of the automatic stereoscopic warehouse. In the process, a speed reducing switch and a stop switch can be arranged at the front end and the rear end of a track where the stacker walks so as to ensure that the stacker does not rush out of a roadway; a speed reducing switch and a stop in-place switch are arranged at the top and the bottom of the lifting guide rail so as to ensure that the stacker carrying platform does not mound and topples; the upper parts of the lower beam assembly 2 and the upper beam assembly 1 are provided with a speed limiter safety gear linkage assembly 8 so as to realize the functions of overspeed protection, safety stop and the like of the cargo carrying platform.
The key point of the embodiment is that the number of goods positions of the stacker is odd, and the lifting telescopic fork is arranged on the goods position positioned in the middle. Of course, the number of cargo spaces may be provided with an even number, and the lifting telescopic fork is provided on one of the two cargo spaces located in the middle. The arrangement described above makes it possible to keep the load on the load platform 5 as balanced as possible during the access operation, avoiding excessive uneven loads on the load platform 5, no matter whether the number of load positions on the stacker is odd or even. Meanwhile, compared with the technical scheme that goods can be conveyed to a single-side goods space only, the arrangement can enable the stacker to set a reasonable access scheme according to specific goods access logic, and the stacker is prevented from being capable of only storing or taking goods according to fixed and single goods access logic. The arrangement effectively improves the versatility of the stacker.
Of course, for accessing a single logical cargo, a lifting telescopic fork may be provided in the side-most cargo space of the cargo bed 5. When goods are stored and taken, the goods are transferred to other goods places according to the sequence respectively through the goods places; or from other cargo locations to a designated shelf via the cargo location. For such a stacker, there may be at least two cargo spaces thereon, and a lifting telescopic fork may be provided on any one of the cargo spaces. According to actual access needs, the goods space with the lifting telescopic fork can be arranged in the middle of the stacker, and is not arranged on the side, for example, one side of the goods space with the lifting telescopic fork is provided with a goods space without the lifting telescopic fork, and the other side of the goods space with the lifting telescopic fork is provided with four goods spaces without the lifting telescopic fork.
The cargo space on the stacker is preferably provided with three, wherein the cargo space in the middle is provided with a lifting telescopic fork. When the picking operation is executed, the lifting telescopic fork on the middle cargo space is lifted and stretches out to pick up the cargoes from the goods shelf. After the goods are taken, the telescopic fork 10 is retracted and falls along with the lifting platform 9, so that the goods on the telescopic fork 10 fall on the conveying mechanism of the middle goods space. The transport mechanism can now transport cargo to cargo spaces on either side so that cargo on the intermediate cargo space can be transferred to cargo spaces on either side thereof. When the next picking operation is performed, the goods picked up by the intermediate goods space can be transferred to the goods space on the other side. And when the last goods taking operation is performed, the goods taken from the intermediate goods space stay on the goods space. At this time, the stacker transfers three goods integrally so as to improve the goods transferring efficiency. When in stock, the intermediate goods space stores the goods temporarily stored on the intermediate goods space to the appointed position of the appointed goods shelf; then the goods on one side of the goods are transferred to the conveying mechanism of the middle goods through the conveying mechanism, so that the goods are stored to the appointed position of the goods shelf through the lifting telescopic fork of the middle goods; and finally, the goods on the other goods space are conveyed to the middle goods space through the conveying mechanism, so that the goods can be stored to the appointed position of the goods shelf through the lifting telescopic fork on the middle goods space. The distance from the side-most goods place to the middle goods place is reduced, and then the path and time for transferring the goods from the side-most goods place to the middle goods place are reduced, so that the transferring time of the goods is reduced, and the stacking efficiency of the stacker is improved.
Of course, five, seven or even more cargo spaces on the stacker may also be provided. If the goods space on the stacker is provided with five, the goods space in the middle is provided with a lifting telescopic fork, and goods are still transferred between the lifting telescopic fork and other goods spaces through the conveying mechanism, and the specific setting can refer to the foregoing. It is emphasized here that the number of cargo spaces on the stacker should be specifically designed according to specific needs. The aforementioned "the positions on the stacker are preferably provided with three" is the optimal solution chosen for the consideration of the transport path of the goods on the stacker, and does not mean that the positions on the stacker can be provided with only three.
In order to improve the efficiency of goods storage and taking, a plurality of goods positions with lifting telescopic forks can be arranged, and the arrangement relation between the goods positions and other goods positions can be referred to the above; or all goods places can be provided with lifting telescopic forks. If the stacker is provided with seven goods places, three goods places are provided with lifting telescopic forks. Then the three goods spaces can be adjacently arranged together, and the goods spaces without lifting telescopic forks are respectively symmetrically arranged at two sides of the three goods spaces; or the four goods spaces without the lifting telescopic fork are arranged in parallel at intervals, and the three goods spaces with the lifting telescopic fork are respectively arranged at intervals of two adjacent goods spaces without the lifting telescopic fork; or three goods shelves provided with the lifting telescopic forks are arranged in parallel at intervals, and two goods spaces without the lifting telescopic forks are respectively arranged in the two intervals formed by the three goods shelves. It is emphasized here that the specific number of positions provided with the lifting telescopic forks and their positional relationship with respect to positions not provided with the lifting telescopic forks are set according to the specific need for accessing the cargo and the access logic.
All goods shelves all have the flexible fork of lift, like being provided with three goods shelves on the stacker, all be provided with flexible fork of lift and conveying mechanism on the three goods shelves to make every goods shelf homoenergetic independently get goods and carry goods to other goods shelves.
The conveyor mechanism is preferably a chain conveyor mechanism 16 or a belt conveyor mechanism. When the conveyor mechanism employs a chain conveyor mechanism 16, it is specifically as follows: the chain conveyor 16 is arranged opposite each other on both sides of the load platform 5 in the direction of extension of the forks, and the chain conveyor 16 on different cargo positions is arranged in alignment. The chain conveying mechanism 16 includes a conveying chain 17 and a power sprocket 18 provided on the elevating platform. In operation, the power sprocket 18 can rotate in both forward and reverse directions so that cargo on the conveyor chain 17 can be transferred between different cargo positions. In the normal tension state of the conveying chain 17, the uppermost chain height is greater than the highest surface of the cargo bed and the telescopic fork 10 in the lowest position, so that the cargo on the telescopic fork 10 can fall on the chain conveying mechanism 16 when the cargo bed and the telescopic fork 10 fall. The arrangement can ensure stable movement of the conveying mechanism and improve carrying capacity of the conveying mechanism. When the conveyor mechanism is a belt conveyor mechanism, a synchronous belt conveyor mechanism is preferably selected. The synchronous wheel of the synchronous belt conveying mechanism refers to the arrangement of the power sprocket 18, and the synchronous belt refers to the arrangement of the conveying chain 17, which is not described herein.
Based on the principle of the above scheme, embodiment 2 of the stacker of the present invention is:
Compared with embodiment 1, the key point of this embodiment 2 is that the lifting telescopic fork includes a lifting mechanism fixedly disposed on the cargo space, a lifting platform 9 is fixedly disposed on a lifting end of the lifting mechanism, and a telescopic fork 10 is disposed on the lifting platform 9. The arrangement can ensure that the movement of the lifting telescopic fork can not interfere with the movement of the conveying mechanism, and ensure the independence and reliability of the movement of the mechanisms. In the actual goods taking work, the lifting mechanism lifts the lifting platform 9, and the telescopic fork 10 on the lifting platform 9 stretches out of the goods taking work after the lifting platform 9 reaches a designated height; after the picking is completed, the telescopic fork 10 is retracted, so that the goods of the telescopic fork 10 can reach the upper part of the conveying mechanism of the goods place along with the fork. The lifting platform 9 is lowered at this time so that the goods can be stably placed on the conveying mechanism of the goods place where the goods are located. The conveying mechanism of the goods space where the lifting telescopic fork is located transfers goods to conveying mechanisms of other goods spaces, so that the goods space with the lifting telescopic fork is vacated, and the next goods taking operation is performed. In the process, as the movement of the lifting telescopic fork and the conveying mechanism of the goods place where the lifting telescopic fork is positioned are mutually independent movement mechanisms, when the goods are moved to the position where the lifting telescopic fork is not interfered with the lifting telescopic fork in the process of transferring the goods to other goods places, the lifting telescopic fork can carry out goods picking operation again, so that the time interval between single goods picking operations is reduced.
In the actual inventory operation, the transport mechanism on the other cargo space first transports the cargo to the transport mechanism on the cargo space with the lifting telescopic fork. At this time, the lifting mechanism lifts the lifting platform 9, and the telescopic fork 10 on the lifting platform 9 stretches out to send the goods to the appointed position of the goods shelf after the lifting platform 9 reaches the appointed height. After the placement, the telescopic fork 10 is retracted, at which point the lifting platform 9 is lowered so that the cargo space can be subjected to the next inventory work. In this process, since the movement of the lifting telescopic fork and the conveying mechanism of the cargo space are mutually independent movement mechanisms, when the lifting telescopic fork performs the inventory work action, the conveying mechanisms on other cargo spaces can synchronously start conveying cargoes to the cargo space so as to reduce the time interval between single inventory works.
Therefore, the efficiency of goods storing and taking operation can be improved by the mode that the lifting telescopic fork and the conveying mechanism are operated separately. On the basis, the lifting mechanism can specifically comprise a lifting driving motor 11 and a driving gear 12 which are fixedly arranged on the cargo platform 5, and a driving rack 13 which is fixedly arranged on the lifting platform 9 and is in meshed transmission with the driving gear 12. The gear rack structure is used as a force transmission path of the lifting mechanism, so that the bearing capacity of the lifting platform 9 and the telescopic fork 10 on the lifting platform can be improved, meanwhile, the motion stability of the lifting platform 9 during lifting is ensured, and the vibration of goods caused by clamping stagnation of the lifting mechanism is prevented. It is easily conceivable that the aforesaid lifting mechanism can also be an oil cylinder, an electric cylinder or an air cylinder arranged between the lifting platform 9 and the cargo platform 5. The loading platform 5 is provided with a power source corresponding to the oil cylinder, the electric cylinder or the air cylinder. The lifting mechanism also comprises a guiding structure in order to achieve guiding of the lifting movement of the lifting platform 9.
On the basis of the above structure, the guiding structure may include a guiding rod 14 fixedly provided on one of the lifting platform 9 and the cargo platform 5 and a guiding hole 15 provided on the other, so as to play a guiding role in the lifting movement of the lifting platform 9, and prevent the lifting platform 9 from being deflected during the lifting process. In the present embodiment, the guiding structure comprises in particular guiding studs welded to the cargo platform 5 and guiding holes 15 provided in the lifting platform 9. In other embodiments, the guiding structure may be a guiding hole 15 formed in the cargo platform 5 and a guiding post welded to the bottom of the lifting platform 9.
The telescopic pallet fork 10 is a bidirectional telescopic pallet fork. Therefore, the stacker can be used for storing and taking goods towards the two sides of the goods shelf, and is more suitable for stacking scenes in which the goods shelf is arranged on the two sides of the roadway. Meanwhile, as the two sides of the stacker can be used for storing and taking cargoes, the stacker can search and store cargoes on two rows of shelves at the same time, and therefore the stacking efficiency of the stacker is effectively improved. Of course, the telescopic fork 10 may also be a one-way telescopic fork when the pallet is arranged on only one side of the stacker.
The parts not mentioned in this example remain identical to example 1.
Embodiments of the cargo platform of the present invention:
