Description

Technical Field

[0001] The present invention relates to the field of automated analytical instruments, and in particular to a single-drive, space-spacing sample conveying track. Background Art

[0002] Sample and material transport functions are often used in many automated analytical equipment and conveying lines. Test samples and materials need to stop at different locations to complete sampling or install accessories. The corresponding workstations often need to leave the track to a dedicated location; in this case, track change and displacement functions are required.

[0003] Most existing conveyor lines with track switching functions use independent conveying units upstream and downstream of the track switching mechanism to achieve relay delivery. The present invention uses a single motor-driven closed conveyor belt to achieve the relay delivery function of two conveyor tracks. This invention has a simple structure, good conveying synchronization, and reduces the control process. Summary of the Invention

[0004] The present invention aims to solve the technical problems of the existing technology, which are complex in structure and high in cost. It provides a new single-drive space-bridge type sample conveying track, which has the characteristics of simple structure, good conveying synchronization, and reduced control process.

[0005] In order to solve the above technical problems, the technical solutions adopted are as follows:

[0006] A single-drive, spaced-apart, cross-connected sample conveying track is used for track-changing operations of sample racks. The single-drive, spaced-apart, cross-connected sample conveying track connects two main conveying tracks. The single-drive, spaced-apart, cross-connected sample conveying track includes a closed conveyor belt driven by a conveying motor through a motor drive wheel.

[0007] The closed conveyor belt is provided with a local disconnection space formed by guiding and restraining three conveyor belt guide wheels at the connection with the main conveyor track. The first conveyor belt guide wheel and the second conveyor belt guide wheel of the three conveyor belt guide wheels are arranged horizontally at intervals, and the third conveyor belt guide wheel is arranged below the center line of the connection line between the first conveyor belt guide wheel and the second conveyor belt guide wheel. The local disconnection space is a recessed space formed by the conveyor belts attached to the first conveyor belt guide wheel, the second conveyor belt guide wheel and the third conveyor belt guide wheel; the local disconnection space is used to place the main conveyor track, and a track changing mechanism for realizing the track changing operation of the sample rack is provided above the local disconnection space.

[0008] In the above solution, for optimization, the closed conveyor belt is further provided with a tension adjustment mechanism for adjusting the tension of the conveyor belt, and the tension adjustment mechanism includes a conveyor belt tensioning wheel, a tensioning swing arm and a conveyor belt tensioning spring.

[0009] Furthermore, the conveyor belt tensioning wheel and the motor driving wheel are arranged horizontally with an interval therebetween and vertically adjacent to each other, and the conveyor belt is wound around the motor driving wheel and the conveyor belt tensioning wheel in an S shape.

[0010] Furthermore, the closed conveyor belt is sequentially wound around two track end wheels, 3×n conveyor belt guide wheels, one motor drive wheel and one conveyor belt tensioning wheel, where n is a positive integer greater than or equal to 1.

[0011] Furthermore, n=2.

[0012] Furthermore, a cut-off baffle controlled by a cut-off motor is provided at the local cut-off space for cutting off the sample rack.

[0013] Furthermore, the cut-off motor switches between the cut-off state and the running state by controlling the cut-off baffle to rotate 90 degrees.

[0014] Furthermore, the track changing mechanism completes the horizontal 90° track changing operation of the sample rack.

[0015] Furthermore, the single-drive space-crossing sample transport track also includes a mechanism support frame, and each unit structure of the single-drive space-crossing sample transport track is supported and fixed by the mechanism support frame.

[0016] Furthermore, the single-drive, air-spaced, cross-connected sample conveying track also includes a sliding groove, which is used to maintain the posture of the sample rack while it is moving. The conveyor belt is driven by a motor drive wheel. When it reaches a position where track change is required, a local break space is formed by the guide constraints of the three conveyor belt guide wheels, and this space just meets the working operation of the track change mechanism. The material and sample rack cross the breakpoint and pass or stop here to perform track change displacement operations, meeting the needs of passing or stopping the track change.

[0017] Beneficial effects of the present invention: The present invention uses a motor to drive a closed conveyor belt to complete the function of relay conveying between two sections of conveyor tracks. The invention has a simple structure, good conveying synchronization, and reduces the control process. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] This embodiment provides a single-drive space-spanning sample transport track, such as Figure 1 、 Figure 2 、 Figure 3 Used for the track changing operation of the sample rack 1, the single-driven air-bridged sample conveying track connects the two main conveying tracks; the single-driven air-bridged sample conveying track includes a closed conveyor belt 3 driven by a conveying motor 14; the closed conveyor belt is provided with a local disconnection space formed by three conveyor belt guide wheels 10-directionally constrained at the connection with the main conveying track, the first conveyor belt guide wheel and the second conveyor belt guide wheel of the three conveyor belt guide wheels are arranged horizontally, and the third conveyor belt guide wheel is arranged below the center line of the connection line between the first conveyor belt guide wheel and the second conveyor belt guide wheel, and the local disconnection space is a recessed space formed by the conveyor belts to which the first conveyor belt guide wheel, the second conveyor belt guide wheel and the third conveyor belt guide wheel are attached; the local disconnection space is used to place the main conveying track, and a track changing mechanism 4 for realizing the track changing operation of the sample rack is provided above the local disconnection space.

[0028] The sliding groove 2 in the figure is used to keep the sample rack 1 in a constant position during the movement. The support frame is used to support the device.

[0029] The track changing mechanism 4 uses an existing structure that can achieve angle change of the sample holder, mainly to complete a 90° conversion.
