Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to solve the problem that cargoes such as a stacking box in the prior art cannot be handled and carried on a large scale, as shown in fig. 1, this embodiment provides a stacking box carrying device, which includes a picking and delivering mechanism and a moving mechanism for driving the picking and delivering mechanism to move, the moving mechanism can be implemented by using a device capable of walking in the prior art, in this embodiment, in order to implement the transportation of the picking and delivering mechanism in the vertical direction, it is preferable to use a truss 10 as the moving mechanism, and to hoist the picking and delivering mechanism on the truss 10.
As shown in fig. 2 to 4, the fetching mechanism specifically includes a first connecting frame 20, an anti-toppling mechanism 30, and a fork 40. Wherein, prevent empting mechanism 30 installs in first link 20 downside, and it is including left guardrail 31, the right guardrail 32 that are relative positional relationship and be relative positional relationship's back guardrail 33, preceding guardrail 34, realizes comprehensively protecting into buttress packing box through forming rail formula structure, specifically, preceding guardrail 34 is as preventing empting the door body of mechanism 30, can realize the switching operation. In order to facilitate real-time observation of stacked containers during the handling process, the left guard rail 31, the right guard rail 32, the rear guard rail 33 and the front guard rail 34 in this embodiment are hollow structures, for example, grid guard rails are adopted.
The pallet fork 40 is movably mounted under the first connecting frame 20, and may be connected between the pallet fork 40 and the first connecting frame 20 by a telescopic device (such as a hydraulic cylinder or an air cylinder) or an electric guide rail, and the front and back movement of the pallet fork 40 is realized by the telescopic movement of the telescopic part of the telescopic device or the sliding of the sliding block on the electric guide rail.
The fork 40 includes a fork frame 41 positioned outside the rear rail 33 and connected to the hydraulic cylinder 50, and a plurality of fork arms 42 extending back and forth below the anti-toppling mechanism 30, the plurality of fork arms 42 being disposed at equal intervals. The four directions of front, rear, left and right defined in this embodiment are determined in the view direction relationship shown in fig. 2, and are not limiting of this embodiment, but are merely for convenience of description of the present invention and for simplification of description. In order to improve the reliability of the connection when the hydraulic cylinder 50 moves the fork 40 back as a whole, in other embodiments, a telescopic structure 12 of the liftable fork 40, such as a tension spring, a hydraulic cylinder, a cylinder, etc., which is arranged obliquely, may be hinged between the fork carriage 41 and the boom 11 of the truss 10, as shown in fig. 9.
The first connecting frame 20 serves both as an integral support for the taking-out and feeding mechanism and for the connection between the taking-out and feeding mechanism and the trolley 10. In order to ensure that the picking and delivering mechanism can be horizontally swung to realize that the picking and delivering mechanism is opposite to the stacking container when the picking and delivering mechanism is forked to the stacking container when the picking and delivering mechanism is moved to the loading position, the first connecting frame 20 can be preferably rotatably hoisted on the picking and delivering mechanism 10 in some embodiments, and in particular, the first connecting frame 20 can be axially fixed on the suspension arm 11 of the picking and delivering mechanism 10 by adopting a thrust bearing.
In this embodiment, since the center of gravity of the picking and delivering mechanism loaded with different cargoes will change, in order to ensure the balance of the transportation process, as shown in fig. 1, multiple lifting points lifting, for example, two lifting points lifting, three lifting points lifting, four lifting points lifting, etc. may be adopted between the first connecting frame 20 and the truss truck 10, so as to ensure stable lifting and balanced stress, specifically, the suspension arm 11 at each lifting point in the truss truck 10 may be a rigid rod and connected to the first connecting frame 20 in a rigid connection manner, and in order to ensure the whole height of the picking and delivering mechanism to be adjustable, that is, the lifting and delivering mechanism is carried out in the vertical direction, in this embodiment, the suspension arm 11 of the truss truck 10 includes a lifting mechanism (not shown in the drawing) for lifting and delivering the picking and delivering mechanism, for example, a telescopic device such as a hydraulic cylinder, an air cylinder, etc. that can be lifted, and in other embodiments adopting multiple lifting points lifting, an electric rail structure capable of driving the picking and delivering mechanism to lift may be installed between the suspension arms 11 of the truss truck 10 and the first connecting frame 20. Of course, if the boom 11 (such as a steel wire rope, a flat sling, a chain, etc.) made of a flexible material is adopted in another embodiment, in order to avoid the shaking of the picking and delivering mechanism, a lifting guiding structure may be additionally arranged between the truss and the picking and delivering mechanism, in order to simplify the structure, the lifting guiding structure may include two guiding drums 13 sleeved with each other, the two guiding drums 13 are respectively fixed on the first connecting frame 20 and the top of the truss 10, and in the process of driving the picking and delivering mechanism to move by the flexible boom 11, the shaking problem of the picking and delivering mechanism can be effectively avoided by using the two guiding drums 13 sleeved with each other, as shown in fig. 9.
The handling equipment of the embodiment can be used for simultaneously loading, unloading and carrying the stacked containers in multiple rows and multiple columns in the horizontal direction and stacked in multiple layers in the vertical direction, and effectively avoids the shaking and tilting problems of the containers by virtue of the anti-tilting mechanism 30 in the carrying process.
In order to avoid interference and collision between the front guard rail 34, the left guard rail 31, the right guard rail 32 and the container when the fork arm 42 forks the container at the loading position, the lifting second connecting frame 60 is installed at the lower side of the first connecting frame 20 in the embodiment, and a plurality of hydraulic cylinders 70 extending in the vertical direction can be arranged between the second connecting frame 60 and the first connecting frame 20, so that the lifting of the second connecting frame 60 is realized through the expansion and contraction of the hydraulic cylinders 70. Before forking the piled containers, the front guard bar 34, the left guard bar 31 and the right guard bar 32 are driven to avoid the piled containers by the rising of the second connecting frame 60; after loading, the front guard rail 34, the left guard rail 31, the right guard rail 32 and the rear guard rail 33 are driven to jointly protect the stacked containers by the descent of the second connecting frame 60. The rear guard rail 33 of this embodiment is fixedly mounted on the underside of the first connecting frame 20, and is not only used for preventing the piled containers from tilting backward, but the rear guard rail 33 also cooperates with the fork 40 which moves backward to push out the piled containers from the fork arm 42 to the unloading position when the piled containers are unloaded at the unloading position, as shown in fig. 5.
For the connection scheme of the front guard rail 34, because the front guard rail 34 needs to be opened and closed, the top of the front guard rail 34 is designed to be rotatably connected to the second connecting frame 60, the included angle between the opened position and the closed position of the front guard rail 34 is larger than 90 degrees, the front guard rail 34 of the embodiment is turned up 180 degrees when being in the opened position, so that the front guard rail 34 does not interfere with stacked containers when being rotated to the opened position, the front guard rail 34 of the embodiment can be manually turned over, and is fixed at the opened position or the closed position by adopting a magnetic structure or a clamping structure, and in other embodiments, the operation of automatically turning over the front guard rail 34 upwards to the opened position can be realized by adopting the structure form of a driving motor, a gear transmission mechanism and a rotating shaft in the prior art. In other embodiments, a vertical motorized rail may be provided between the front rail 34 and the second connecting frame 60 to vertically slidably couple the front rail 34 to the second connecting frame 60 in the open and closed positions.
Because the length of the stacking containers to be handled in the left-right direction may be changed, in order to improve the versatility of the handling apparatus, the tops of the left guard rail 31 and the right guard rail 32 may be connected to the second connecting frame 60 in a manner of sliding left and right, and specifically, an electric guide rail or a telescopic device extending left and right may be mounted at the bottom of the second connecting frame 60, and the left and right sliding of the left guard rail 31 and the right guard rail 32 may be realized by the movement of the slide block on the electric guide rail or the telescopic movement of the telescopic part on the telescopic device. Before forking the piled containers, the left guard bar 31 and the right guard bar 32 move back to reserve enough avoiding space for the piled containers; after the piled containers are forked, the left guard bar 31 and the right guard bar 32 move towards each other to reliably clamp the piled containers. Because the tops of the left guard rail 31 and the right guard rail 32 are connected to the second connecting frame 60, in order to ensure that the bottoms of the left guard rail 31 and the right guard rail 32 can still exert strong clamping force, the distance between the left guard rail 31 and/or the right guard rail 32 decreases from top to bottom, i.e. the left guard rail 31 and the right guard rail 32 are obliquely arranged from top to bottom towards each other. The reverse movement (backward movement, forward movement) of the left guard rail 31 and the right guard rail 32 may be performed simultaneously with the lifting movement.
Because the length of the stacking container in the front-rear direction of the stacking container to be handled may also change, in order to further improve the universality of the handling equipment, the fetching and delivering mechanism further comprises a partition plate 80 installed on the lower side of the first connecting frame 20 for protecting the stacking container, the partition plate 80 is provided with a plurality of front-rear protection lengths of the anti-toppling mechanism 30, and in order to realize the detachable installation of the partition plate 80, the clamp 21 for clamping the partition plate 80 can be arranged on the lower side of the first connecting frame 20. In order to avoid interference between the partition plate 80 and the second connecting frame 60, the second connecting frame 60 may be correspondingly provided with a long-strip insertion hole 61 into which the partition plate 80 is inserted. The dual retention of the clips 21, the elongated receptacles also better secures the spacer 80.
When the first connecting frame 20 is provided with the clip 21, the partition 80 can be matched with the front guard rail 34 and/or the rear guard rail 33 to realize front and rear protection of the stacked containers; when the first connecting frame 20 is provided with the plurality of clips 21 arranged at intervals, the spacing between the partition plate 80 and the front guard rail 34 or the rear guard rail 33 can be adjusted by the clamping fit of the partition plate 80 and the different clips 21, so that the handling of stacked containers with different lengths in the front-rear direction can be better protected.
The partition 80 is not only beneficial to the handling of stacked containers with different lengths in the front-rear direction, but also can realize the simultaneous handling of multiple stacked containers. In this embodiment, in particular, the 3 clips 21 are disposed on the lower side of the first connecting frame 20, taking the case of clamping 2 partition boards 80 on the lower side of the first connecting frame 20, for convenience of explanation, the 2 partition boards 80 are respectively: the first partition plate 80 and the second partition plate 80 are three groups of stacking containers which are required to be assembled, disassembled and transported, and the stacking containers are respectively: the first, second and third packing boxes comprise a packing box. Before loading, the two partition plates 80 are removed, after the fork arms 42 fork the first container to form a stack, the first partition plates 80 are clamped at the lower side of the first connecting frame 20, and form front and rear protective walls of the first container to form a stack with the rear guard 33; then, the second stacking container is forked, after the fork arms 42 fork the second stacking container, the second partition plate 80 is clamped on the lower side of the first connecting frame 20, and the first partition plate 80 and the second partition plate 80 form front and rear protective walls of the second stacking container; the third set of stacked containers is then forked and after the fork arms 42 fork the third set of stacked containers, the front side rails 34 are rotated to the closed position which, with the second partition 80, form the front and rear guard walls for the third set of stacked containers. The unloading process of the three-pack cargo box is referred to as the loading process and will not be described in detail herein.
Since the fork arm 42 needs to extend into the bottom of the palletized container when the palletized container is palletized at the loading position, in order to facilitate the palletized container being palletized by the fork arm 42, the palletized container handling apparatus of the present embodiment includes a tray 90 which is adapted to be inserted with the fork arm 42, as shown in fig. 6, and a plurality of grooves 91 which are adapted to be inserted with the fork arm 42 are provided at the top of the tray 90. After the fork arms 42 fork to form a stack of containers, the pallet 90 remains at the loading location without following the movement of the handling equipment, reducing the use of the pallet 90 and reducing the turnover frequency of the pallet 90.
In this embodiment, a touch sensor (not shown in the drawings) is installed at the bottom of the fork arm 42, and in the process that the truss truck 10 drives the picking mechanism to descend to approach the unloading position, the touch sensor can send a signal when the picking mechanism contacts the unloading position, and the truss truck 10 stops driving the picking mechanism to descend continuously according to the signal sent by the touch sensor. At this time, the fork arm 42 is in micro-contact with the unloading position, so that the reaction force of the fork arm 42 received by the unloading position is small, and the fork arm is convenient to move backwards and withdraw from the position below the anti-toppling mechanism 30.
To further mitigate drag during unloading of a palletized container, in other embodiments, as shown in fig. 7 and 8, a roller yoke 42 or a belt yoke 42 may be employed, the roller yoke 42 may include two links and a plurality of small rollers rotatably connected between the two links, and a conveyor belt may be formed over the roller yoke 42. In the process that the fork arm 42 moves backwards to withdraw from the lower part of the anti-toppling mechanism 30, sliding friction between the fork arm 42 and a piled container is improved to rolling friction, so that the resistance of the fork arm 42 when moving backwards to withdraw can be effectively reduced.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the invention in any way, and any person skilled in the art may make modifications or alterations to the disclosed technical content to the equivalent embodiments. However, any simple modification, equivalent variation and variation of the above embodiments according to the technical substance of the present invention still fall within the protection scope of the technical solution of the present invention.
