The walking aid driving wheels 22021 and the walking aid driven wheels 22022 are arranged at intervals in sequence, and preferably, the two sides of the walking aid driven wheels 22022 are provided with the walking aid driving wheels 22021. The outer diameters of the walking aid driving wheels 22021 and the walking aid driven wheels 22022 are sequentially increased in the longitudinal direction, so that the longitudinal section of the walking aid plane roller bed set 220 is wedge-shaped. The walking aid driving wheel 22021 is rigidly connected with a transmission wheel shaft 22014, the transmission wheel shaft 22014 penetrates through the walking aid plane roller bed frame 2203 to transmit power from the transmission wheel 22013 to the walking aid driving wheel 22021, and further to transmit power from the walking aid plane roller bed 2201 to the walking aid plane roller bed 2202.

The walking aid belt 22023 is sleeved on the walking aid driving wheel 22021 and the walking aid driven wheel 22022, and the walking aid driving wheel 22021 drives the walking aid driven wheel 22022 to rotate through the walking aid belt 22023. The upper plane of the walking aid belt 22023 is higher than the upper plane of the walking aid plane roller rack 2203, and the lower plane of the walking aid belt 22023 is higher than the lower plane of the walking aid plane roller rack 2203.

By the above structure, as shown in fig. 7 and 8, when the lower working surface of the goods transposition device 2 is tightly attached to the working plane and pushed forward or retreated, referring to fig. 7, the driving wheel 22012 of the walking aid plane roller way set 220 is tightly attached to the working plane, the gravity type walking aid roller way 22 becomes a powered plane roller way by the friction transmission force generated by the driving wheel 22012 and the working plane, and the moving direction of the goods on the roller way is opposite to the working direction of the goods transposition device 2; when the goods transposition device 2 is lifted away from the operation plane, referring to fig. 8, the walking aid plane roller set 220 sinks under the action of gravity, the upper plane of the gravity walking aid roller table 22 is not higher than the upper plane of the grid base plate 23, the gravity walking aid roller table 22 loses the action of the power plane roller table, and at the moment, the upper operation plane 24 and the upper plane of the grid base plate 23 are on the same plane and only play a role of a bearing plane.

In a preferred embodiment of the present application, the longitudinal length of the gravity table 22 is greater than the sum of the lengths of the antifriction front tongue 20 and the gravity table 21.

As shown in fig. 19, the leveling mechanism 25 is disposed below the grid substrate 23. As shown in fig. 12-15, the leveling mechanism 25 includes a leveling wheel lever 250, a leveling link 251, a leveling wheel 252, a leveling ramp 253, and a leveling cylinder 254. Specifically, as shown in fig. 12 and 13, the leveling sloping block 253 is disposed on the bottom plane of the slot in the longitudinal long slot 255 with a downward opening at the lower part of the goods transposing device 2; two sets of leveling rollers 252 are distributed at both ends of the elongated leveling roller bar 250 and are disposed together in the longitudinal elongated slot 255. At the rear end of the leveling wheel rod 250, the leveling wheel rod 250 is connected with the telescopic end of a leveling cylinder 254 through a leveling connecting rod 251, and the leveling cylinder 254 is longitudinally arranged at the lower part of a mixed conveying roller bed 3 which is connected with the goods transposition device 2 and is described below. As shown in fig. 14 and 15, the leveling sloping block 253 is provided with a platform section, the height of the platform section of the leveling sloping block 253 is designed to be larger than that of the rear sloping block, and the thin end of the leveling sloping block 253 faces the leveling cylinder 254, namely the rear end of the goods transposition device 2. In order to ensure that the goods transposition device 2 runs smoothly in operation, at least two groups of the leveling mechanisms 25 are arranged.

The operation principle of the leveling mechanism 25 is that when the goods transposition device 2 needs to operate normally, the leveling mechanism 25 is in a non-working state, as shown in fig. 14, at this time, the leveling cylinder 254 is in a zero stroke, the leveling roller 252 is in contact with the thinnest end of the leveling inclined block 253, and the goods transposition device 2 operates normally according to the function; when the forward pushing intake and backward pulling discharge functions of the locking goods transposition device 2 are required, the leveling mechanism 25 needs to enter a working state, as shown in fig. 15, the leveling cylinder 254 needs to be pushed forward until the maximum stroke is reached, the leveling roller 252 runs to a platform section through the inclined surface section of the leveling inclined block 253 under the forward pushing action of the leveling cylinder 254, and the leveling roller 252 lifts the leveling inclined block 253 and stabilizes on the platform section; along with the lifting of the pushing and leveling inclined block 253, the goods transposition device 2 is also lifted, and the height of the platform section of the pushing and leveling inclined block 253 is designed to be larger than that of the rear inclined block, so that the upper working surface 24 becomes a horizontal plane after the goods transposition device 2 is lifted. Meanwhile, the driving wheel 22012 of the gravity type walking aid roller table 22 at the bottom of the goods transposition device 2 is separated from the working surface, the goods transposition device 2 loses the functions of forward pushing, drawing and discharging, only the function of a bearing platform is remained, and the supporting and moving of the goods transposition device 2 are realized by the pushing and leveling roller 252.

The leveling mechanism 25 is used for releasing or locking the forward-pushing intake and backward-pulling discharge functions of the goods transposition device 2 according to the operation requirement during loading and unloading, and switching the upper operation surface 24 of the goods transposition device 2 between an inclined surface and a horizontal surface: when the goods transposition device 2 is positioned on an inclined plane, the goods transposition device 2 releases the functions of forward pushing, drawing and discharging, and the reciprocating movement of the goods transposition device 2 is realized by the rolling of the driving wheel 22012 of the gravity type walking aid roller table 22; when the goods transposition device 2 is in a horizontal plane, the upper working surface 24 of the goods transposition device 2 and the upper plane of a mixed conveying roller bed 3 to be described below are combined into the same plane, the lower working surface of the goods transposition device 2 is lifted to leave the working surface, the forward pushing and drawing-in and backward pulling and discharging functions of the goods transposition device 2 are locked, and the reciprocating movement of the goods transposition device 2 is realized by the rolling of a leveling roller 252 of a leveling mechanism 25.

According to the above structure of the structure, the working principle of the goods transposition device 2 is as follows: under the conditions of 'packaging of angle bead strips at the bottom edge of the head-on side of unit goods' and 'arrangement of a vertical rear blocking wall of goods' in the operation method of the invention, when the unit goods without tray operation need to be loaded, unloaded or transported, the goods transposition device 2 is directly inserted into a gap between the angle bead strips at the bottom edge of the head-on side of the unit goods and a stacking plane, under the guiding action of the excircle angle bead strips and the longitudinal packing strips at the bottom of each piece of goods at the bottom layer of the unit goods and the reaction force action of the vertical rear blocking wall of the goods, and under the continuous propelling action of the goods transposition device 2, the unit goods without tray operation gradually pass through the friction-reducing front tongue section 20, the gravity type following roller way 21 section and the gravity type walking aid roller way 22 section, and are finally completely accommodated on the upper operation surface 24 of the goods transposition device 2. In the process, the relative movement of the friction-reducing front tongue 20 section and the bottom surface of the goods is sliding movement with low friction coefficient, and the moving power is formed by the continuous propelling acting force of the goods transposition device 2 and the reaction force of the vertical rear retaining wall of the unit goods which are processed without pallets. The relative movement of the gravity type following roller way 21 section and the gravity type walking aid roller way 22 section and the bottom surface of the goods is non-sliding plane movement, wherein the plane movement power of the gravity type following roller way 21 section is also formed by the continuous propelling acting force of the goods transposition device 2 and the counter acting force of the vertical rear retaining wall of the unit goods without tray operation; the moving power of the gravity type walking aid roller table 22 section is formed by the continuous propelling action of the goods transposition device 2, the walking aid power of the gravity type walking aid roller table 22 and the counter force of the vertical rear retaining wall of the unit goods without pallets. When the unit goods without the pallet are completely accommodated in the upper working surface 24 of the goods transposing device 2, the carrying or moving operation of the unit goods without the pallet can be carried out. During the carrying or moving operation of the goods without the pallet units, the goods transposition device 2 is lifted, the gravity type following roller way 21 and the gravity type walking roller way 22 lose the function of the roller ways and only play a part in supporting the goods, and the unit goods for the operation without the pallet units are still on the goods transposition device 2. When the unit goods which are carried or moved and do not carry out tray operation are stacked on the next stacking plane, the lower operation surface of the goods transposition device 2 can be attached to the stacking plane and withdrawn backwards, and the unit goods which do not carry out tray operation and are positioned on the operation surface 24 on the goods transposition device 2 are spitted on the next stacking plane under the combined action of the moving power of the gravity type walking aid roller way 22 opposite to the withdrawing direction and the inclination of the upper operation surface 24. Because the longitudinal length of the gravity type rollator table 22 of the working surface 24 on the goods transposition device 2 is larger than the sum of the longitudinal lengths of the antifriction front tongue 20 and the gravity type roller table 21, i.e. the process may continue until more than half of the unit load subjected to palletless operations is discharged, whereafter under the influence of gravity on the stacking plane of more than half of the unit load subjected to palletless operations, under the combined action of the following action of the gravity type following roller way 21, the sliding action of the low friction coefficient of the antifriction front tongue 20 and the inclination of the upper operation surface 24 of the goods transposition device 2, the unit goods which are subjected to the tray-free operation are continuously discharged from the upper operation surface 24 of the goods transposition device 2 until the goods transposition device 2 completely exits from the bottom surface of the unit goods which are subjected to the tray-free operation, and the stacking operation of the unit goods which are subjected to the tray-free operation on the next plane is completed.

Based on the working principle of the goods transposition device 2, the goods transposition device 2 can be used for a transposition fork of a forklift without a pallet unit, a pallet unit goods loading and unloading platform device without a pallet unit at the front end of a collection loading and unloading platform, and a pallet unit goods loading and unloading tail plate device without a pallet unit.

Carrying and plane stacking storage operation: when the forklift provided with the goods transposition device 2 transposition fork implements transposition operation of a goods stacking plane without a tray unit, carrying operation is simultaneously carried out, and when plane stacking is completed in carrying, the unit goods without the tray operation are always placed under the condition of a vertical rear baffle wall with a certain area; 3. conveying operation: when the goods transposition device 2 is used for transposition operation of a stacking plane of unit goods without trays at the front end of the collection loading and unloading platform, the goods transposition device 2 also undertakes conveying operation of the unit goods without trays during mutual transposition between the unit goods on the collection loading and unloading platform and the carriage bottom plate.

The 'goods vertical rear retaining wall' operation condition of the invention means that in the operation process, unit goods without tray operation are always placed under the condition of a vertical rear retaining wall with a certain area, and the rear retaining wall can be naturally formed or specially created: such as the unit goods without the tray, the front end plate of the carriage, the thick wall body, the upright post with the plane, the vertical baffle plate equipment for fixing the foundation and the like in a row, the unit goods without the tray can be oppositely and synchronously inserted in a backrest mode to obtain the working condition of the goods vertical rear baffle wall.

Because the fork 5 of the goods transposition device has the functions of pushing forwards and containing and pulling backwards and spitting out the unit goods without tray for operation, the unit goods without tray for operation can be transposed from the original stacking plane to the next stacking plane.

The working principle of the mixed conveying roller way 3 is as follows: as shown in fig. 21, when the lifting cylinder 3021 performs a pushing action, the lifting push-pull rod 302 drives the lifting roller set 3020 to make the lifting wedge 3010 drive the lifting support rod 301 to rise upwards, and as the upper plane of the lifting support rod 301 rises, the load distribution between the mobile plane roller 30 and the free plane roller 31 will change: when the stroke of the lifting oil cylinder 3021 is maximum, the lifting support rod 301 is lifted to the highest position, the moving plane roller way 30 is higher than the free plane roller way 31, and at this time, the moving plane roller way 30 can be regarded as bearing the weight of all the cargos. As shown in fig. 22, when the lifting cylinder 3021 performs a pulling operation, the lifting push-pull rod 302 drives the lifting roller set 3020, so that the lifting wedge 3010 drives the lifting support rod 301 to descend to the moving plane roller 30 below the free plane roller 31 under the action of gravity, and at this time, the free plane roller 31 can be regarded as bearing the weight of all the cargo.

When the push-pull oil cylinder 3031 performs pushing or pulling actions, the push-pull long rod 303 and the lifting support rod 301 driven by the push-pull long rod 303 perform reciprocating rolling movement on the bottom groove roller bed 304 through the push-pull roller 3030 together: that is, when the lifting support rod 301 is lifted upwards to the highest position, the moving plane roller table 30 can perform full-load reciprocating movement; when the lifting support rod 301 is lifted upwards to be at other specific positions lower than the highest position, the movable plane roller way 30 can perform incomplete load movement, and at the moment, partial load is born by the free plane roller way 31 and is driven by the movable plane roller way 30 to move; when the lifting support rod 301 falls back down to the lowest position, the free plane roller 31 is higher than the moving plane roller 30, the moving plane roller 30 is considered to be unloaded, and the moving plane roller 30 can perform the return movement. In this way, the joint operation or independent operation of the movable flat roller way 30 and the free flat roller way 31 is realized by controlling the operation height of the movable flat roller way 30.

It should be noted that when the moving plane roller table 30 is lower than the free plane roller table 31, the free plane roller table 31 becomes an unpowered roller table, and the load on the free plane roller table 31 can be movably conveyed by applying a longitudinal horizontal force to the load on the free plane roller table 31.

The above operations are repeated according to the operation requirements, so that the collecting operation and the collecting and conveying operation of the stacked unit goods without pallets on the mixed conveying roller way 3 can be realized.

s2, stacking operation and tray loading operation: and the palletizing unit goods without pallets are converted into single palletizing unit goods with pallets by the pallet removing and palletizing device 62, and are warehoused by a conveying line or a common forklift.

Example 7

The present embodiment is substantially the same as embodiment 5, except that the unitized logistics operation system in the present embodiment includes, in addition to embodiment 5, a fork 5 of a cargo transposing device and a cross-connecting assembly device 7.

As shown in fig. 35-37, the interface module 7 includes an access lift platform 70 and a transfer platform 71. Wherein the longitudinal length of the access lift platform 70 is related to the longitudinal length of the pallet during loading and unloading, and the longitudinal length of the transfer platform 71 is twice as long as that of the access lift platform 70.

The transfer assembly 7 is provided at the rear end of the tray and stack stacking and unstacking device 62, and is a device for replacing the function of connecting the loading and unloading end 620 of the tray and stack stacking and unstacking device 62 after removing the loading and unloading end. The function of the transfer assembly 7 is to engage the single stack unit load without pallets with the collective loading and unloading unit 6 during loading and unloading by operation of the forklift equipped with the fork 5 of the load transposing device.

As shown in fig. 35 and 37, the access lift platform 70 includes a lift platform upper plane 700, a longitudinal groove 701, a trough bottom raceway 702, a lift mechanism 703, a platform frame 704, and a tailgate 705;

the control lifting mechanism 703 can control the lifting of the in-out lifting platform 70. When the upper plane 700 of the lifting platform rises to the highest position, the upper plane 700 of the lifting platform, the longitudinal groove 701, the groove bottom roller way 702, the upper plane of the conversion conveying line 711 of the conversion conveying platform 71 and the long groove 710 of the conversion roller way are correspondingly butted respectively. When the upper plane 700 of the lifting platform descends to the lowest position, the rear baffle 705 is exposed and vertically blocked in the forward direction of the upper plane 700 of the lifting platform; when the upper plane 700 of the lifting platform is at the highest position or the lowest position, the upper plane 700 of the lifting platform is used as a stacking plane for the operation forklift to be connected with the aggregate loading and unloading unit without the pallet unit.

As shown in fig. 36, the conversion conveying platform 71 includes a moving plane roller table 30, a conversion roller table long groove 710, a conversion conveying line 711, a conversion driving device 712, a conversion platform base frame 713, and a vertical supporting structure 714; it should be noted that the structure of the mobile plane roller table 30 corresponds to the structure of the mobile plane roller table 30 of the collective loading and unloading platform 60.

A moving plane roller way 30 is arranged in the long groove 710 of the conversion roller way, and the moving plane roller way 30 is equal to the long groove 710 of the conversion roller way, namely equal to the conversion conveying platform 71; the movable flat roller bed 30 can perform a lifting motion in the switching grooved roller bed 710 and can perform a longitudinal reciprocating motion only in a direction of entering and exiting the lifting platform 70. When the moving plane roller way 30 is at the lowest position, namely the original position, the upper plane of the moving plane roller way 30 is not higher than the upper plane of the conversion conveying line 711; when the moving plane roller way 30 is at the highest position, the upper plane of the moving plane roller way 30 is higher than the upper plane of the conversion conveying line 711. The longitudinal moving distance of the moving plane roller table 30 is the same as the longitudinal length of the in-and-out lifting platform 70. The long groove 710 of the conversion roller way and the conversion conveying line 711 are arranged at intervals; the conversion conveying lines 711 are driven by a driving device 712 to move, and the array conversion conveying lines 720 are connected through a conveying mechanism; transfer feed line 711 is supported by vertical support structure 724.

The operation procedure of the delivery/assembly device 7:

when loading, the in-out lifting platform 70 is controlled to be lifted to the highest position, and the longitudinal movement function of the mobile plane roller way 30 in the original state is controlled, so that the mobile plane roller way 30 enters the longitudinal groove 701 of the in-out lifting platform 70 from the long conversion roller way groove 710 of the conversion conveying platform 71.

Because the upper plane of the movable plane roller way 30 can be switched in a lifting way, the upper plane of the movable plane roller way 30 and the upper plane 700 of the lifting platform can form a relatively flat integral plane, and the in-and-out lifting platform 70 can receive single stacks of unit goods which are carried and transposed by the forklift provided with the fork 5 of the goods transposition device to carry out operation without pallets.

Next, the lifting function of the movable flat roller way 30 is controlled to lift the upper plane of the movable flat roller way 30, and the single pile on the in-out lifting platform 70 is used for the unit goods without pallets, so that the single pile is separated from the support of the upper plane 700 of the lifting platform of the in-out lifting platform 70 and is completely supported by the movable flat roller way 30.

By controlling the longitudinal movement function of the mobile plane roller way 30, the mobile plane roller way 30 carries the unit goods of the single stack without pallet operation, and moves to the initial position of the mobile plane roller way 30, so that the unit goods of the single stack without pallet operation are moved and conveyed to the conversion conveying platform 71.

The descending function of the moving plane roller way 30 is controlled to make the upper plane of the moving plane roller way 30 descend to the initial position, namely not higher than the upper plane of the conversion conveying line 711 of the conversion conveying platform 71, so that the supporting task of the unit goods without tray operation of single stack is transferred to the conversion conveying line 711, and then the unit goods without tray operation is conveyed to the tray removing and stacking and separating device of the integrated handling unit 6 by the conversion conveying line 711 to enter the next loading operation process of the unit goods without tray.

Further, when unloading, the unloading operation of goods without the tray unit can be carried out according to the reverse flow process of the loading process. During unloading, when a single pile of unit goods without pallets is moved and conveyed to the in-out lifting platform 70 and is subjected to transposition operation with a forklift provided with a fork 5 of the goods transposition device, the transposition operation condition of the goods vertical rear retaining wall without pallets needs to be established. At this time, the vertical rear blocking wall can be changed by vertically collecting several stacks of single-stacked unit goods without trays on the transfer combination device 7 and the rear end of the front tray-loading and stacking device 62. When the originally established operation condition of 'vertical goods rear retaining wall' can not meet the operation requirement any more, the in-out lifting platform 70 can be lowered, the rear baffle 705 arranged at the front end of the in-out lifting platform 70 is exposed, and the forklift provided with the goods transposition device fork 5 can smoothly complete the transposition warehousing operation of single-stack unit goods without pallets at the unloading tail end by utilizing the vertical rear retaining wall action of the rear baffle 705.

Application scenario of example 7: under the condition of the operation method of the invention, according to business needs, the following operations can be implemented by using the embodiment:

①, under the condition of flat goods position at both the delivery warehouse and the arrival warehouse, the united operation of the fork truck with the goods transposition device 5, the cross-over combination device 7 and the integrated loading and unloading machine set 6 can be used to perform the unit integrated operation without pallets for the unit goods in the whole process of the logistics business, wherein, the integrated stacking unit operation without pallets for the unit goods is performed in the loading and unloading link of the transportation.

②, under the condition that the sending warehouse is a three-dimensional warehouse and the arrival warehouse has a plane goods space, the unit goods with trays in the sending warehouse can be assembled by the assembly loading and unloading unit 6 for the unit goods without trays, and during the unloading operation of the arrival warehouse, the forklift with the fork 5 of the goods transposition device can be independently used to enter the carriage with the rear door, so as to independently complete the unloading operation of the unit goods without trays and the warehousing and stacking operation of the plane goods space of the arrival warehouse.
