Detailed Description

For the purpose of making apparent the objects, technical solutions and advantages of the present utility model, the present utility model will be further described in detail with reference to the accompanying drawings and examples, it being understood that the specific examples described herein are for illustration only and are not intended to limit the present utility model.

Referring to fig. 1, 2 and 3, the utility model provides an intelligent number plate conveying device, which comprises a roller type transmission mechanism 1 and a conveying structure matched with the roller type transmission mechanism;

the roller type transmission mechanism 1 comprises a plurality of transmission rollers 11 which are fixed in position and driven by an external driving assembly to rotate; the drive assembly is rotated by driving the driving roller 11 to effect the transmission of the number plate (this roller transmission mechanism is a means known to those skilled in the art and is referred to in most devices, for example in CN202022743496.5, a roller conveyor named a conveying stack, and is not described in any greater detail in this application).

Gaps exist among the driving rollers 11; the conveying structure comprises a tray 3 which is driven by a lifting structure to move along a vertical elliptic track and is always in a horizontal state; the tray 3 includes a plurality of gear shaping teeth penetrating through the gaps, and the gear shaping teeth penetrate through the gaps between the plurality of driving rollers 11 when the tray 3 moves in the vertical direction and passes through the roller driving mechanism 1. When the position error appears in the number plate (here detection of number plate position can detect through visual sensor, and this application does not mention, is conventional art), tray 3 passes the clearance between the driving roller 11 from bottom to top and will be located the temporary support of number plate on the driving roller 11 to place in the top briefly, when there is great clearance between the number plate on the driving roller 11, tray 3 descends and will temporarily store the number plate and place on driving roller 11 again, and the number plate of placing fills the clearance, guarantees the homogeneity in clearance between the number plate, realizes the position adjustment of number plate.

Referring to fig. 1, the lifting structure 2 includes a spider 21, a gear set vertically disposed on the spider 21, and a transmission chain 23 (shown in fig. 3) sleeved on the gear set; in this example, the gear set is formed by two sets of gears 22, and at least one set of gears is connected to a drive motor (not shown); the support frame 5 for supporting the tray 3 is arranged on the transmission chain 23, a mounting shaft 31 is arranged at the end part of the tray 3, and the mounting shaft 31 is rotatably connected with the support frame 5. When the driving tray 3 carries out the circulation transmission, the driving motor drives the gear set to rotate and further drives the transmission chain 23 to carry out the transmission, and the supporting frame 5 is further driven by the transmission chain 23 and carries out the circulation transmission according to the track.

A positioning structure for positioning along the direction of the mounting shaft 31 is arranged between the support frame 5 and the conveying support frame 21; the positioning structure ensures that the position of the supporting frame 5 and the conveying support 21 is fixed, and the supporting frame 5 is driven to drive the transmission chain 23 to be separated from the gear set under the action of gravity of the tray 3.

The positioning structure comprises a positioning plate 6 arranged in a conveying bracket 21; the supporting frame 5 comprises two clamping plates 51 (shown in fig. 4) which are symmetrically arranged relative to the positioning plate 6 and are fixedly connected with each other; a positioning space for matching with the positioning plate 6 is formed between the two clamping plates 51, and the positioning plate 6 is clamped by the two clamping plates 51; referring to fig. 6, two clamping plates 51 are fixedly connected with the chain shaft of the transmission chain 23 through a connecting block 53. When the transmission chain 23 drives the support frame 5 to transmit, the positioning plate 6 is always arranged in the positioning space formed by the two clamping plates 51, so that the support frame 5 is positioned under the condition that the normal transmission of the support frame 5 is not affected.

Further, the lateral end of the supporting frame 5 is provided with a roller 52 contacting with the positioning plate 6. During positioning, the roller 52 is contacted with the positioning plate 6, so that the transmission friction force between the support frame 5 and the positioning plate 6 is reduced (direct contact between the support frame 5 and the positioning plate 6 is avoided).

Referring to fig. 4 and 5, the tray 3 is driven by a balancing mechanism to be always in a horizontal state; this is because only the tray 3 is always in a horizontal state when it is driven: on the one hand, stable supporting of the number plate is realized (if the tray 3 is subjected to angle change (non-horizontal state), the number plate can slide off from the tray 3), and on the other hand, the gear shaping is ensured to pass through gaps among a plurality of driving rollers 11.

The balancing mechanism comprises a plurality of groups of balancing wheels 71 (shown in fig. 4) which are arranged on the mounting shaft 31 and are mutually matched, and a plurality of balancing plates 72 (shown in fig. 5) which are arranged inside the conveying bracket 21 and are arranged corresponding to the balancing wheels 71; in this example, the balance wheels 71 are provided with four balance wheels 71, each balance wheel 71 is fixedly connected to the mounting shaft 31 through a connecting rod 73, the four connecting rods 73 form a cross-shaped structure, and the four balance wheels 71 are all arranged on different planes.

Four balancing plates 72 are correspondingly arranged, an arc track (shown in fig. 5) is arranged at the inner edge of each balancing plate 72, each balancing wheel 71 is always attached to the arc track of the inner edge of the corresponding balancing plate 72, and under the action of the arc track and the balancing wheels 71, the balancing wheels 71 roll along the inner edge of the balancing plate 72 to drive the mounting shaft 31 to rotate and lock.

Because the roller type transmission mechanism is always in a transmission working state, in the lifting operation of the tray 3, the situation that the number plate cannot accurately fall into the lifting area of the tray 3, so that the tray 3 cannot normally lift the number plate can occur, the application is improved in the following way, and a telescopic stop block structure for blocking the number plate from advancing is arranged at the lifting position of the tray 3; the telescopic stopper structure comprises a telescopic device 32 fixedly installed on a frame of a roller type transmission mechanism and a stopper 33 installed at the output end of the telescopic device 32, and in the example, the telescopic device 32 adopts a telescopic cylinder. The number plate is in normal conveying process on the roller type transmission mechanism, the telescopic device 32 is in a contracted state, the stop block 33 does not affect normal conveying of the number plate, however, when the number plate needs to be lifted, the telescopic device 32 stretches out (shown in fig. 7), the number plate scheduled to be lifted is blocked to a lifting position by the stop block 33, and finally, the number plate is lifted by the tray 3.

Of course, the present utility model is capable of other various embodiments and its several details are capable of modification and variation in light of the present utility model, as will be apparent to those skilled in the art, without departing from the spirit and scope of the utility model as defined in the appended claims.
