Description

Technical Field

[0003] In addition, the existing code scanning can also be transmitted by means of a conveyor belt, and during the transmission process, it passes through a scanner, which scans the QR code, bar code and other identification codes on the passing goods to realize automatic transmission and scanning. However, in order to ensure the accuracy of the scanning, the transmission rate of the conveyor belt needs to be maintained below a certain rate to prevent the transmission rate from being too fast and causing missed scans. Therefore, the transmission rate of the conveyor belt is limited, which makes the efficiency of code scanning and shipment low. Utility Model Content

[0036] In order to enable those skilled in the art to better understand the present invention, and thus to more clearly define the scope of protection claimed by the present invention, the present invention is described in detail below with respect to certain specific embodiments of the present invention. It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0037] like Figure 1-Figure 6 As shown, the utility model discloses an automatic code reader, comprising:

[0038] Rack 1;

[0039] Conveyor belt 2, the conveyor belt 2 is arranged on the frame 1, and the conveyor belt 2 is provided with a cargo receiving area 21, a code scanning area 22, and a cargo discharging area 23 from left to right, and the conveyor belt 2 is used to sequentially transport the cargo through the cargo receiving area 21, the code scanning area 22, and the cargo discharging area 23;

[0040] The barcode scanner 31 is disposed on the frame 1 and located above the barcode scanning area 22 to scan the goods passing through the barcode scanning area 22 downward;

[0041] A first positioning cylinder 4, which is disposed on the frame 1 and is located at one end of the code scanning area 22 facing the goods receiving area 21;

[0042] The second positioning cylinder 5 is disposed on the frame 1 , and the second positioning cylinder 5 is located at one end of the code scanning area 22 facing the shipping area 23 .

[0043] Specifically, the cargo in this embodiment is a blister tray 9 for loading top cover sheets, and the blister tray 9 can accommodate a plurality of top cover sheets.

[0044] Therefore, the blister trays 9 that need to be scanned are placed in the incoming goods area 21 in turn, and the blister trays 9 can be quickly transferred to the scanning area 22 under the action of the conveyor belt 2. Then the first positioning cylinder 4 and the second positioning cylinder 5 work to clamp the blister tray 9 between the first positioning cylinder 4 and the second positioning cylinder 5, which not only has the function of guiding the direction of the blister tray 9, but also makes the blister tray 9 stationary relative to the scanner 31, so that the scanner 31 can accurately read the identification code on the blister tray 9. After the reading is completed, the first positioning cylinder 4 and the second positioning cylinder 5 work to release the restriction on the blister tray 9, and the blister tray 9 can move toward the shipping area 23 to leave the scanning area 22 to complete the shipment.

[0045] In addition, this embodiment also includes:

[0046] A first sensor system 61, which is disposed on the frame 1 and is located in the code scanning area 22 to detect that the goods have completely entered the code scanning area 22;

[0047] The second sensor system 62 is disposed on the frame 1 . The second sensor system 62 is located in the shipping area 23 to detect when the goods have completely left the code scanning area 22 .

[0048] Therefore, the first sensing system 61 can detect that the blister tray 9 enters the code scanning area 22, so as to drive the first positioning cylinder 4 to work and cut off the connection between the code scanning area 22 and the incoming goods area 21, thereby preventing multiple blister trays 9 from entering the code scanning area 22 and affecting the code scanning. The second sensing system 62 can detect that the blister tray 9 completely leaves the code scanning area 22, so as to drive the second positioning cylinder 5 to work and cut off the connection between the code scanning area 22 and the outgoing goods area 23, thereby preventing the blister tray 9 that has not been scanned from leaving the code scanning area 22 and causing a code missing phenomenon.

[0049] Preferably, the first sensing system 61 and the second sensing system 62 in this embodiment both use counter-beam sensors, specifically infrared counter-beam sensors, so that the two counter-beam components are arranged on the front and rear sides of the conveyor belt 2, so that when no blister tray 9 passes by, the receiving end receives the signal from the transmitting end, and when the blister tray 9 passes by, the blister tray 9 blocks the infrared rays so that the receiving end cannot receive the signal from the transmitting end, and the detection is accurate and the structure is simple.

[0050] Specifically, the first positioning cylinder 4 and the second positioning cylinder 5 in this embodiment are both located on the rear side of the conveyor belt 2, and their output shafts are both facing forward, and the output shafts of the first positioning cylinder 4 and the second positioning cylinder 5 are both provided with positioning stops 71 by means of nuts tightened, and the right side of each positioning stop 71 is also fixedly installed with a guide bar 72 extending forward and backward by means of bolts, and correspondingly, a slide seat 73 is fixedly installed on the frame 1, so that the corresponding guide bar 72 cooperates with the slide seat 73 to achieve smoother sliding guidance, so that the positioning of the blister plate 9 by the positioning stop 71 is more stably.

[0058] Specifically, the second flip rod 85 in the present embodiment is cylindrical, and a third cylindrical hole (not marked in the figure) is vertically penetrated on the second mounting seat 84 for the sliding rod 81 to pass through, and a notch is formed on one radial side of the third cylindrical hole, and the third locking member is a bolt, so that the third cylindrical hole can be contracted by the bolt in cooperation with the second mounting seat 84 to clamp and fix the sliding rod 81, and a fourth cylindrical hole (not marked in the figure) is penetrated front and back on the second mounting seat 84 for the second flip rod 85 to pass through, and a notch is formed on one radial side of the fourth cylindrical hole, and the fourth locking member is a bolt, so that the fourth cylindrical hole can be contracted by the bolt in cooperation with the second mounting seat 84 to clamp and fix the second flip rod 85.
