By the action of the downward bias, the first or the second wheel set can move up and down. The second or first wheel set corresponding to the unbiased wheel seat may be reset away from the rail plane, for example, by a spring force. In one example, a first wheel mounted to the first outboard panel or a second wheel mounted to the second outboard panel moves downward to contact a corresponding track when the first wheel mount or the second wheel mount is biased downward. In a preferred embodiment, the outer contour parts of the first reversing cam and the second reversing cam are designed to be overlapped, so that the four sets of wheel sets are in contact with the rail at the same time, and the four sets of wheel sets are positioned on the rail more stably.
Referring to fig. 7 and 10, as best shown in fig. 10, in the present embodiment, a travel driving motor 351 is connected to a travel driving gear group 352, and 352 transmits a rotational motion to a first travel driving shaft 353, and both ends of the first travel driving shaft 353 are connected to the travel wheels 340 of the second wheel group through a belt transmission (not shown) so that the transport robot can travel on the first track. The travel drive gear set 352 simultaneously rotates the bevel gear 354, and simultaneously transmits power to the second travel drive shaft 355. Both ends of the second travel driving shaft 355 drive the travel wheels 330 of the first wheel set through belt transmission, so that the transfer robot can travel on the second track.
The reversing motor 361 is connected to the first reversing transmission shaft 362, and drives the first reversing transmission shaft 363 through a belt transmission (not shown), two sets of cams 364 and 365 (a first reversing cam and a second reversing cam) with opposite directions are respectively fixed at two ends of the first reversing transmission shaft 363, when the cam shaft rotates, the two sets of cams respectively bias the first wheel seat or the second wheel seat downwards to the driven roller, so that the first or second wheel set can move up and down, and the second or first wheel set can be reset away from the track plane through spring force. And the four groups of wheel sets can be contacted with the track by designing the outer contour parts of the first reversing cam and the second reversing cam to be partially overlapped, so that the four groups of wheel sets are more stably positioned on the track. When the cam shaft rotates, the two groups of cams respectively bias the first wheel seat or the second wheel seat downwards so as to drive the first wheel set or the second wheel set to move downwards, so that the first wheel train component and the second wheel train component can alternately contact one group of wheels with the track by virtue of the height difference caused by the opposite directions of the cams.
Preferably, in the wheel-seat box of the transport robot, a driven roller located below and abutting against the first reversing cam or the second reversing cam may be provided in at least one of the first wheel seat and the second wheel seat.
For example, as shown in fig. 8 or 9, a first driven roller 375 may be disposed in the first wheel base 370, and a second driven roller 385 may be disposed in the second wheel base 380. When fitted in place, the cams 364 and 365 abut against the first driven roller 375 and the second driven roller 385, respectively. As shown in fig. 9, the second driven roller 385 is mounted on the second driven roller shaft holder 386 through a driven roller rotation shaft 385S. Similarly, the first driven roller 375 is also mounted on the first driven roller shaft seat 376 through a rotating shaft.
Similarly, the second reversing drive shaft 366 on the other side drives the corresponding set of cams to effect the reversing synchronously. For example, the first and second reversing drive shafts 363, 366 may transmit power and maintain synchronization via a belt or chain at each end of the shafts.
The first and second cams 364, 365 of each cam set may be fixed on the same camshaft. To further ensure stability of the reversing process, the displacement curves of the first and second wheel bases 370, 380 in the first angular segment may be the same, while the displacement curves of the first and second wheel bases 370, 380 in the second angular segment may be opposite. In order to achieve that all wheel sets contact the rail simultaneously, the cam displacement curves may have a partial overlap. For example, the displacement curves of first wheel base 370 and second wheel base 380 within the third angular segment may overlap.
Specifically, the displacement curves of the first wheel seat 370 and the second wheel seat 380 in the first angle section are the same, which means that the profile curves of the first cam 364 and the second cam 365 in a certain angle range are the same, for example, in the range of 0 ° to 10 °, preferably in the range of 0 ° to 3 °, the profile curves of the first cam 364 and the second cam 365 are the same, and then the contact height of the first wheel seat and the second wheel seat with the rail is not changed at the same time. The displacement curves of the first wheel seat and the second wheel seat in the angular segment are opposite, which means that the profile curves of the first cam 364 and the second cam 365 in a certain angular range are symmetrical to each other, and when the cam shaft rotates in the angular range, the first wheel seat and the second wheel seat move at the same speed and in opposite directions.
In one embodiment of the invention, the first cam and the second cam are identical in shape, the first cam and the second cam having an angular deviation in the mounting direction. Preferably, the angular deviation of the first cam from the second cam in the mounting direction is 180 degrees, in other words, the phase angle of the first cam differs from the phase angle of the second cam by 180 degrees.
The first top plate 371 and the first bottom plate 372 are parallel to each other, and the first top plate 372 and the first bottom plate 372 are both shaped like an "F", i.e., the length of the transverse plate located at the middle of the longitudinal plate is shorter than the length of the transverse plate located at the end of the longitudinal plate.
In the structure of the second wheel seat shown in fig. 9, the second top plate 381 and the second bottom plate 382 have a groove, and the groove is matched with the convex portion of the middle portion of the first top plate 371 and the convex portion of the middle portion of the first bottom plate 372, so that the shape of the combination of the first wheel seat and the second wheel seat is substantially square. The structure makes the wheel seat box of the transport robot more compact, and improves the strength of each wheel seat.
Further, a guiding component for guiding the wheel seat to move up and down, such as a guide rod shown in the figure and a spring (not shown) sleeved on the guide rod, such as a guide post 376 shown in fig. 8, are also arranged in the wheel seat. Because each guide rod is positioned between the top plate and the bottom plate of each wheel seat, the spring is particularly arranged between the bottom plate and the sliding block. The number of the guide rods in the first wheel seat and the second wheel seat is at least two. Illustratively, when the first cam drives the first wheel seat to descend, the first cam pushes the first wheel seat to descend, and the spring between the first bottom plate and the sliding block is compressed; when the first cam drives the first wheel seat to ascend, the first wheel seat is always contacted with the profile of the first cam by the counterforce of the spring between the sliding block and the first bottom plate.
Preferably, as shown in fig. 2, in one embodiment of the warehouse, the warehouse may further include a maintenance platform area 600, preferably disposed proximate to the item storage area. The service platform area may be provided with service area rails for access machines to enter or leave the item storage area.
In one embodiment of the warehouse according to the present disclosure, the access retrieval station may be disposed on a floor of a building of the warehouse, and the floor of the item storage area is at the same height as or higher than the floor of the building.
The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the protection scope of the technical solution of the present invention.
