Detailed implementation manners

[0034] The present invention will be further described below with reference to the drawings and embodiments.

[0035] Embodiment 1

[0036] An optical sensor information recognition device for shelf commodities, as Figures 1-7As shown in the figure, it includes a support frame 1, a first mounting plate 2, a shelf 3, a second mounting plate 4, an identification mechanism 5, a display mechanism 6 and a material pushing mechanism 7. On the left and right sides of the support frame 1, there are respectively three second mounting plates 4 and three first mounting plates 2. The support frame 1 is made of aluminum alloy, which is light in weight and hard in strength. Between the first mounting plate 2 and the second mounting plate 4, there is a shelf 3 for placing goods connected by bolts. The shelf 3 is arranged with a downward slope at the front part. There are four placement slots on the shelf 3. Between the shelf 3 and the support frame 1, there are an identification mechanism 5 and a display mechanism 6. And there is a material pushing mechanism 7 on the placement slots.

[0037] As Figure 5 shown in the figure, the identification mechanism 5 includes a fixing plate 51, an optical sensor 52, a top cover 53 and a display screen 54. At the front side of the lower part of the shelf 3, there is a fixing plate 51 connected by bolts. In the middle of the fixing plate 51, there is an optical sensor 52 for scanning goods. At the top of the support frame 1, there is a top cover 53 connected by bolts. The top cover 53 is arranged in a C shape with the opening facing downwards. Between the top cover 53 and the support frame 1, there is a display screen 54 for displaying the information of the scanned goods. The display screen 54 is electrically connected to the optical sensor 52.

[0038] As Figure 3 and Figure 4 shown in the figure, the display mechanism 6 includes a guide rail 61, a display board 62, a hinge plate 63, a hinge block 64, an electric slide rail 65 and a pressing plate 66. At the rear side of the middle part of the shelf 3, there is an electric slide rail 65 connected by bolts. At the rear side of the lower part of the electric slide rail 65, there is a pressing plate 66. At the rear side of the shelf 3, there are two hinge plates 63 rotatably arranged. The two hinge plates 63 are respectively located on the left and right sides of the electric slide rail 65. At the lower part of the hinge plate 63, there is a hinge block 64 rotatably arranged. The hinge plate 63 is in contact with the pressing plate 66. Between the shelf 3 and the support frame 1, there is a guide rail 61 connected by bolts. On the upper side of the guide rail 61, there are display boards 62 for displaying goods information symmetrically arranged left and right in a sliding manner. The display boards 62 are in sliding cooperation with the guide rail 61 and the support frame 1. The display boards 62 on the left and right sides are respectively in sliding cooperation with the hinge blocks 64 on the left and right sides.

[0039] As Figure 6 and Figure 7 shown in the figure, the material pushing mechanism 7 includes a guide plate 71, a material pushing plate 72, a plug rod 73 and a counterweight 74. Between the front and rear side walls of the placement slot on the shelf 3, there is a guide plate 71 connected by bolts. On the guide plate 71, there is a material pushing plate 72 slidingly arranged. On the upper side of the material pushing plate 72, there is a plug rod 73 connected by bolts. At the rear side of the upper part of the material pushing plate 72, there is a counterweight 74 connected.

[0040] First, the operator pushes the pusher plate 72 backward through the insertion rod 73, then places the commodities on the upper side of the guide plate 71 from back to front. After releasing the insertion rod 73, since the shelf 3 is arranged with its front part inclined downward, the pusher plate 72 will push the commodities forward under the gravity of the counterweight 74, so that the commodities are always located in front of the placement groove. When people take the first commodity, the commodities at the back will replace the position of the first commodity. The operator places the bar code of the commodity in front of the optical sensor 52 for scanning, and the optical sensor 52 inputs the commodity information onto the display screen 54. The operator can understand the commodity information in detail through the display screen 54, and thus can perform the operation of identifying the commodity information. The operator starts the electric slide rail 65 to move upward, and the electric slide rail 65 drives the pressing plate 66 to move upward. During the upward movement of the pressing plate 66, it will contact the hinge plate 63, and the hinge plate 63 will rotate away from the electric slide rail 65 under the force. The hinge plate 63 pushes the display board 62 away from the electric slide rail 65 through the hinge block 64, and the display board 62 slides on the guide rail 61 to expand the display board 62. Then the electric slide rail 65 is turned off, and thus the information of the commodity can be displayed through the display board 62 to better promote the commodity. The operator starts the electric slide rail 65 to move downward, and the electric slide rail 65 drives the pressing plate 66 to move downward. During the downward movement of the pressing plate 66, it will disengage from the hinge plate 63, and the hinge plate 63 will rotate toward the electric slide rail 65 under the action of gravity. The hinge plate 63 pulls the display board 62 toward the electric slide rail 65 through the hinge block 64, and the display board 62 slides on the guide rail 61, and thus the display board 62 can be retracted.

[0041] Embodiment 2

[0042] On the basis of Embodiment 1, as Figure 1 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 shown, it further includes a hanging mechanism 8. The hanging mechanism 8 includes a mounting rod 81, a hook 82, a socket 83, a fixing block 84, a limiting block 85 and a connecting spring 86. Cavities are opened on the upper left side wall of the placement groove of the shelf 3 and on the upper right side of the second mounting plate 4. The mounting rod 81 is slidably arranged in the cavity. Ten hooks 82 for hanging commodities are evenly spaced and connected to the lower side of the mounting rod 81 by means of bolts. The hook 82 is slidably matched with the cavity. A socket 83 is opened on the right rear part of the mounting rod 81, and the insertion rod 73 can be snap-fitted with the socket 83. A spring groove is opened on the upper rear side wall of the placement groove of the shelf 3, and a limiting block 85 is connected to the middle of the lower side wall of the spring groove by means of bolts. The mounting rod 81 can contact the limiting block 85 when moving to the right. A fixing block 84 is connected to the right side wall of the spring groove, and a connecting spring 86 is connected between the fixing block 84 and the mounting rod 81. The connecting spring 86 passes through the limiting block 85.

[0043] At first, the installation rod 81 contacts the limit block 85. The operator pushes the installation rod 81 to the left. During the leftward movement of the installation rod 81, it will disengage from the limit block 85, and the connecting spring 86 enters the stretched state, causing the installation rod 81 to be located inside the cavity on the second mounting plate 4. Then, the pusher plate 72 is pushed backward so that the pusher plate 72 is located at the rearmost side of the placement groove. The operator then releases the installation rod 81, and the connecting spring 86 resets. Under the action of the reset of the connecting spring 86, the installation rod 81 moves to the right and contacts the limit block 85, and the socket 83 on the installation rod 81 is engaged with the insertion rod 73 on the pusher plate 72 in a snap-fit manner. In this way, the pusher plate 72 can be retracted and fixed. At this time, the operator can hang the commodity on the hook 82 for sale.

[0044] Embodiment 3

[0045] Based on Embodiment 2, as Figure 2 、 Figure 8 and Figure 9 shown, there is also a fixing mechanism 9. The fixing mechanism 9 includes a connecting rod 91, a push rod 92, a clamping block 93 and a reset spring 94. The front end of the installation rod 81 is slidably provided with the clamping block 93. A reset spring 94 is connected between the clamping block 93 and the installation rod 81. The clamping block 93 is engaged with the front side wall of the cavity. The push rod 92 is slidably arranged in the front part of the cavity. The push rod 92 can contact the clamping block 93. The four push rods 92 are connected by bolts to form a connecting rod 91.

[0046] The operator moves the installation rod 81 to the left, and the connecting spring 86 enters the stretched state, causing the installation rod 81 to be located inside the cavity on the second mounting plate 4. The installation rod 81 will drive the clamping block 93 and the hook 82 to move to the left. During the leftward movement of the clamping block 93, it will contact the second mounting plate 4, and the clamping block 93 will then move backward under the force, and the reset spring 94 enters the compressed state. When the clamping block 93 moves continuously to the left, it will gradually disengage from the second mounting plate 4, and the reset spring 94 resets. Under the action of the reset of the reset spring 94, the clamping block 93 moves forward, so that the clamping block 93 is stuck in the cavity. In this way, the hook 82 can be retracted and the placement method of the commodity can be changed. The operator pushes the connecting rod 91 backward, and the connecting rod 91 pushes the clamping block 93 backward through the push rod 92, and the reset spring 94 enters the compressed state. The clamping block 93 disengages from the cavity, and the connecting spring 86 resets. Under the action of the reset of the connecting spring 86, the installation rod 81 drives the clamping block 93 and the hook 82 to move to the right. During the rightward movement of the clamping block 93, it will disengage from the second mounting plate 4, and the reset spring 94 resets. During the rightward movement of the installation rod 81, it will contact the limit block 85. At this time, the commodity can be hung through the hook 82.

[0047] Embodiment 4

[0048] Based on Embodiment 3, as Figure 1 、Figure 10 and Figure 12 As shown in Figure 12 , it further includes a merging mechanism 10. The merging mechanism 10 includes a guide rod 101, a pushing block 102, an L-shaped plate 103, and a pushing plate 104. The left part of the connecting rod 91 is connected to the L-shaped plate 103. The left side of the lower part of the second mounting plate 4 is connected to the guide rod 101 by means of bolt connection. The front part of the guide rod 101 is slidably sleeved with the pushing block 102. The pushing block 102 can contact the L-shaped plate 103 when moving backward. A chute is formed in the lower part of the second mounting plate 4. The pushing plate 104 is connected between the four pushing plates 72 by means of bolt connection. The left part of the pushing plate 104 slidably penetrates through the chute and is connected to the pushing block 102.

[0049] At first, the hook 82 is in a retracted state. When it is necessary to open the hook 82, the operator pushes the pushing plate 72 backward to retract the pushing plate 72. The pushing plate 72 drives the pushing block 102 to move backward through the pushing plate 104. The pushing block 102 will contact the L-shaped plate 103 during the backward movement. The L-shaped plate 103 is forced to move backward, and the L-shaped plate 103 then drives the push rod 92 to move backward through the connecting rod 91. In this way, the hook 82 can be opened while the pushing plate 72 is retracted backward.

[0050] The above embodiments only represent the preferred embodiments of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements, and substitutions can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
