In the chemical industry, when the same container is used for containing different chemicals, the operator usually inputs the information code on the outer wall of the container, for example, the product information on the bar code. For example, the operator may use a hand-held information collector (scanner) to sequentially scan the barcode on the outer wall of each product container 3, or may pass the product containers 3 through a fixed-position scanning device to collect data information from the barcode on the outer wall of the container.

The method for collecting the product information firstly causes the labor intensity of operators to be too high, the data collection efficiency to be low, the bar codes are dislocated due to reasons of different placing directions of the bar codes on the outer wall of the container, vibration in the moving process and the like, and the bar codes do not uniformly face a code scanner or a scanning instrument, so that inconvenience is brought to the operators or the product information cannot be effectively collected; in the case of conveying a plurality of containers by the conveyor belt 13, the operator is required to have skillful operation and faster response speed, and the accuracy of the recorded data information is lower.

As shown in fig. 3, the clamping portion 21 may alternatively include two fixing plates 211 symmetrically disposed at both sides of the second end of the product container 3 and two movable clamping plates 212 coupled between the two fixing plates 211, the two clamping plates 212 being disposed opposite to each other; wherein the two clamping plates 212 may be moved toward each other to clamp the second end of the product container 3 or the two clamping plates 212 may be moved away from each other to unclamp the second end of the product container 3.

In this embodiment, the clamping portion 21 of the information collecting device 2 for clamping the second end of the product container 3 specifically includes two fixing plates 211 and two movable clamping plates 212, wherein the two fixing plates 211 are respectively located at two sides of the second end of the product container 3, the two clamping plates 212 are connected between the two fixing plates 211, and the two clamping plates 212 are oppositely disposed, for example, the clamping plates 212 may be perpendicular to the extending direction of the fixing plates 211, and the two clamping plates 212 are respectively located at two opposite sides of the second end of the product container 3.

Two splint 212 are at the removal in-process, can be close to each other, thereby can press from both sides the second end of product container 3 through two splint 212, when product container 3 moves to corresponding with information acquisition device 2, two splint 212 are close to each other and press from both sides tight product container 3 second end, the both ends of product container 3 are all fixed firm like this, can guarantee product container 3's stability, for example guarantee that product container 3 does not take place phenomenons such as rocking or skew, so as to ensure that the information code of product container 3 outer wall can aim at data acquisition portion 22, so that the product information on the information code is effectively gathered to data acquisition portion 22.

After data information acquisition is completed, the two clamping plates 212 are far away from each other, the second end of the product container 3 is loosened, so that the conveying device 1 can continue to drive the product container 3 to move away from the position corresponding to the information acquisition device 2 after stopping rotating to move, then the next product container 3 can move to correspond to the information acquisition device 2, and the information acquisition device 2 acquires product information in the information code of the next product container 3 once. Circulating in this way, the product containers 3 are sequentially conveyed to the position of the information acquisition device 2 through the conveying device 1, and the information acquisition device 2 finishes the acquisition of the product information of the next product container 3, which is not described in detail herein.

How to enter the clamping portion 21 of the information acquisition device 2, the product container 3 can be clamped by the two clamping plates 212, and the product container 3 can be moved out of the clamping portion 21 after information acquisition is completed, in a possible embodiment, the two fixing plates 211 can both be provided with through grooves 2111, the product container 3 can enter between the two fixing plates 211 through the through groove 2111 of one fixing plate 211 and stay during the moving process so as to acquire product information, and after the product information acquisition is completed, the conveying device 1 drives the product container 3 to move out of the information acquisition device 2 from the through groove 2111 of the other fixing plate 211.

It will be appreciated that the cross-sectional area of the through slot 2111 should be slightly larger than the outer profile area of the second end of the product container 3, so that the second end of the product container 3 enters between the two retaining plates 211 through the through slot 2111.

To improve the stability of the clamping plates 212 against the second end of the product container 3, in one possible embodiment, each clamping plate 212 may be provided with at least one roller shaft 213, and the roller shafts 213 on the two clamping plates 212 may abut against the outer wall of the second end of the product container 3 during the approach of the two clamping plates 212 to clamp the second end of the product container 3.

As shown in fig. 3 or fig. 5, in the present embodiment, each clamping plate 212 is provided with a roller shaft 213, when the two clamping plates 212 approach each other and clamp the second end of the product container 3, specifically, the roller shaft 213 clamps the second end of the product container 3, the roller shaft 213 can clamp the second end of the product container 3 more firmly, so that the stability of the product container 3 can be improved, and the information code of the outer wall of the product container 3 can correspond to the data acquisition part 22 more accurately.

For example, each of the clamping plates 212 may be provided with one roller shaft 213, and for the arrangement position of the roller shafts 213, the roller shafts 213 of the two clamping plates 212 may be symmetrical, and taking the outer wall of the second end of the product container 3 as a cylinder as an example, the roller shafts 213 of the two clamping plates 212 may correspond to two ends of the diameter of the second end of the product container 3, which is not described herein again.

As shown in fig. 3 or 5, in an embodiment, two roller shafts 213 may be disposed on each clamping plate 212 at intervals, and the roller shafts 213 may be connected to the clamping plates 212 through rotating shafts. By providing two rollers 213 on each clamp plate 212, the two rollers 213 may be spaced apart from each other, such that the two rollers 213 contact different portions of one side of the second end of the product container 3, and the four rollers 213 on the two clamp plates 212 contact four portions of the second end of the product container 3, thereby providing a more stable clamping of the second end of the product container 3.

In addition, the roller shaft 213 may be connected to the clamping plate 212 through a rotating shaft, so that when the product container 3 is clamped or rotated, the roller shaft 213 may rotate relative to the clamping plate 212, so as to better clamp the product container 3, and the roller shaft 213 may rotate to drive the product container 3 to rotate, so that the information code of the outer wall of the product container 3 may be aligned with the data collecting part 22 during the rotation of the product container 3.

It can be understood that, by providing the rotatable roller shaft 213 to clamp the second end of the product container 3, even if the information code of the outer wall of the product container 3 is not directed to the data collecting part 22 at the initial position, the information code of the outer wall of the product container 3 can be aligned with the data collecting part 22 during the rotation of the product container 3 driven by the roller shaft 213, so that the data collecting part 22 collects the product information in the information code. Therefore, the information collecting device 2 can accurately and effectively collect the product information, and the situation that the product information cannot be collected because the information code is not aligned with the data collecting part 22 is avoided, which can improve the accuracy of collecting the product information by the information collecting device 2.

In practical applications, as for the material of the roller shaft 213, the roller shaft 213 may be a flexible roller shaft 213 such as a rubber roller shaft 213, so that when the roller shaft 213 clamps the second end of the product container 3, the product container 3 presses the roller shaft 213, and the generated pressing force can increase the clamping force of the roller shaft 213 on the product container 3; in addition, the roller shaft 213 made of rubber or silica gel has a certain protection effect on the product container 3, and in the rotation process of the product container 3, the scraping damage of the roller shaft 213 on the outer wall of the product container 3 can be reduced.

For the roller shaft 213 driving the product container 3 to rotate, specifically, at least one first motor 214 may be disposed on the clamping plate 212, and the first motor 214 may be connected to the at least one roller shaft 213 and drive the roller shaft 213 to rotate. As shown in fig. 3 and 5, the first motor 214 is disposed on the clamping plate 212, and the first motor 214 is connected to at least one roller shaft 213, so that the first motor 214 can drive the roller shaft 213 to rotate, the roller shaft 213 can drive the product container 3 to rotate by the friction between the roller shaft 213 and the outer wall of the second end of the product container 3, and since the other roller shafts 213 can rotate relative to the clamping plate 212, the product container 3 can drive the other roller shafts 213 to rotate, so that the information code of the outer wall of the product container 3 can be rotated to correspond to the data acquisition part 22.

In a specific application, the first motor 214 may be controlled to drive the roller shaft 213 to rotate so as to rotate the product container 3 at least one turn, so that no matter which direction the information code on the outer wall of the product container 3 initially faces, during the rotation of the product container 3, the information code must rotate to correspond to the data acquisition portion 22, which is not described herein again.

As shown in fig. 2, the data collecting part 22 may be connected to the fixing plate 211 through the extension rod 23, and the data collecting part 22 may be provided with a circumferential outer wall of the information code corresponding to the product container 3, and the roller shaft 213 drives the product container 3 to rotate so that the information code is directly opposite to the data collecting part 22.

Because the clamping part 21 corresponds to the second end of the product container 3, taking the product container 3 as an example, for the case that the information code is arranged on the circumferential outer wall of the bottle body, because the information code has a certain distance from the clamping part 21, and in order to make the data acquisition part 22 correspond to the information code, the data acquisition part 22 can be connected to the fixing plate 211 through the extension rod 23, so that the data acquisition part 22 corresponds to the circumferential outer wall of the position where the information code of the product container 3 is located, that is, the data acquisition part 22 and the information code are in the same height range, so that in the process that the roller shaft 213 drives the product container 3 to rotate, the information code can correspond to the data acquisition part 22.

As shown in fig. 5, for the connection of the roller shaft 213 and the clamping plate 212, in one embodiment, the clamping plate 212 may have a mounting groove 2121 thereon, and the roller shaft 213 may be located in the mounting groove 2121. In this embodiment, the clamping plate 212 may have a certain width, so that the mounting groove 2121 may be provided on the clamping plate 212, and the roller shaft 213 may be mounted in the mounting groove 2121, and the roller shaft 213 may be connected to a groove wall of the mounting groove 2121 through a rotation shaft, so that the roller shaft 213 may rotate in the mounting groove 2121.
