Referring to fig. 1-4, the double track apparatus further includes a return track having an input end capable of communicating with a downstream section 1-2 of the upper track and an output end capable of communicating with an upstream section 1-1 of the upper track. The input end of the downstream section 1-2 of the upper-layer rail is provided with a tube detection device, and the tube detection device is used for detecting whether a sample tube exists on the sample support.

After the upstream section 1-1 of the upper-layer rail conveys the sample support to the detection mechanism, the detection mechanism firstly performs lofting (placing a sample tube) on the sample support, then detects the sample in the sample tube, if the detection is finished, the sample tube on the sample support is taken away, the sample support at the moment becomes an empty support, and the empty sample support is conveyed to the input end of the downstream section 1-2 of the upper-layer rail.

At the input end of the downstream section 1-2 of the upper rail, the sample holder is inspected by the inspection device. If no sample tube is detected on the sample holder, which indicates that the sample holder is an empty holder, the downstream section 1-2 of the upper rail is communicated with the lower rail 2, and the sample holder is conveyed to the lower rail 2. If a sample tube is detected on the sample holder, the sample holder needs to be sent to the detection mechanism again for detection, then the downstream section 1-2 of the upper-layer rail is communicated with the U-turn rail, the sample holder enters the upstream section 1-1 of the upper-layer rail again through the U-turn rail, and then the sample holder is conveyed into the detection mechanism. This is cycled through until no sample tube is detected on the sample tray.

In this first cycle, it is possible to ensure that the sample on the sample holder is gradually subjected to different detection processes by the detection mechanism. The second cycle of the utility model is composed of an upstream section 1-1 of the upper rail, a detection mechanism, a downstream section 1-2 of the upper rail and a lower rail 2. In this second cycle, the sample holder undergoes lofting, detection, transport to the lower rail 2, and lofting, in that order. In this way, it can be ensured that empty pallets are constantly buffered in the lower track 2.

Referring to fig. 4, the return rail 3 specifically includes a first tuning rail 3-1, a return rail body 3-2, and a second tuning rail 3-3. The first turnaround track 3-1 is used to transport sample trays on the downstream section 1-2 of the upper track to the return track body 3-2. The second turnaround track 3-3 is capable of transporting the sample holders from the return track body 3-2 to the upstream section 1-1 of the upper track, followed by the upstream section 1-1 of the upper track transporting the sample holders to the detection mechanism. In this embodiment, the first switch rail 3-1 is used to connect the downstream section 1-2 of the upper rail and the return rail body 3-2, and the second switch rail 3-3 is used to connect the return rail body 3-2 and the upstream section 1-1 of the upper rail.

The utility model discloses the input of the downstream section 1-2 of upper rail has set up first guiding mechanism 4-1. When the sample tray is detected by the tube detecting device to have a sample thereon, the first guide mechanism 4-1 is opened to form a guide from the downstream section 1-2 of the upper rail to the first turnaround rail 3-1. Thus, the sample holder conveyed to the input end of the downstream section 1-2 of the upper rail enters the first shunting rail 3-1 under the guiding action of the first guiding mechanism 4-1, and then is conveyed to the return rail body 3-2 by the first shunting rail 3-1.

The transfer means can transfer samples from the output end of the lower rail 2 to the input end of the upstream section 1-1 of the upper rail, or the transfer means can transfer samples from the output end of the downstream section 1-2 of the upper rail to the input end of the lower rail 2.

The upper input end stop is also arranged at the input end of the upper rail, namely the upper input end stop is arranged at the input end of the upstream section 1-1 of the upper rail. The upper input barrier is disabled to control whether the upper track receives a new sample holder. If the upper layer rail is in a full state, the upper layer input end is blocked and closed, and a new sample holder is prevented from entering. An upper output stop is also provided at the output of the downstream section 1-2 of the upper rail to prevent the sample in the upper rail from moving out at will. A lower output stop is also provided at the output end of the lower rail 2 to prevent the sample holder in the lower rail 2 from being removed at will.

The utility model discloses a two kinds of transfer devices are first transfer device 5 and second transfer device respectively. First, the first transfer device 5 will be described, with reference to the accompanying figures 5-7: the first transfer device 5 comprises a receiving plate 7-1 and a moving assembly. The receiving plate 7-1 has an opening 7-2 for the entry and removal of the sample. The output end of the movement assembly is capable of outputting movement from the output end of the lower track 2 to the input end of the upstream section 1-1 of the upper track, or from the output end of the downstream section 1-2 of the upper track to the input end of the lower track 2. The connecting and supporting plate 7-1 is connected to the output end of the moving assembly.

If the first transfer device 5 is located at the input end of the upstream section 1-1 of the upper rail, the receiving plate 7-1 is to transfer the sample in the lower rail 2 onto the upstream section 1-1 of the upper rail. The moving process of the receiving plate 7-1 is as follows: the receiving and supporting plate 7-1 is firstly stopped at the output end of the lower layer rail 2, after the lower layer rail 2 conveys the sample support to the receiving and supporting plate 7-1, the moving assembly drives the receiving and supporting plate 7-1 to move to the input end of the upstream section 1-1 of the upper layer rail, and then the sample support is gradually entered into the upstream section 1-1 of the upper layer rail under the drive of the upstream section 1-1 of the upper layer rail. Then the receiving plate 7-1 returns according to the original path and stops at the output end of the lower layer rail 2 again to transfer the next sample tray.

If the first transfer means 5 is located at the output end of the downstream section 1-2 of the upper rail, the receiving plate 7-1 is to transfer samples from the output end of the downstream section 1-2 of the upper rail to the input end of the lower rail 2. The moving process of the receiving plate 7-1 is as follows: the receiving and supporting plate 7-1 is firstly stopped at the output end of the downstream section 1-2 of the upper-layer rail, after the downstream section 1-2 of the upper-layer rail conveys the sample holder to the receiving and supporting plate 7-1, the receiving and supporting plate 7-1 is driven by the moving assembly to move to the input end of the lower-layer rail 2, and then the sample holder in the receiving and supporting plate 7-1 is driven by the lower-layer rail 2 to move into the lower-layer rail 2. The receiving plate 7-1 then returns to the output end of the downstream section 1-2 of the upper track as it is, waiting for the next sample holder.

It is then particularly how the sample holders on the receiving plate 7-1 are moved away from the receiving plate 7-1 into the lower rail 2 or into the upstream section 1-1 of the upper rail, and particularly how the sample holders in the lower rail 2 or in the downstream section 1-2 of the upper rail are moved into the receiving plate 7-1. To the problem, the utility model discloses make following design: at first the utility model provides a sample holds in palm the main part and is cylindric to form undergauge portion at the middle part that the sample held in the palm. The upper part of the diameter-reduced part is an upper large-diameter part 7-6, and the lower part is a lower large-diameter part. The opening 7-2 on the supporting plate 7-1 is matched with the reduced diameter part of the sample holder, namely the reduced diameter part can enter and exit the opening 7-2. The supporting plate 7-1 is also provided with a clamping groove 7-3, the clamping groove 7-3 is communicated with the opening 7-2, and the clamping groove 7-3 can clamp the sample support. Furthermore, the utility model also arranges a sinking platform 7-5 in the slot 7-3, and the lower end surface of the upper large diameter part 7-6 of the sample support can be located on the sinking platform 7-5.

It should be noted that the return rail body 3-2 is substantially parallel to the upstream section 1-1 of the upper rail or to the downstream section 1-2 of the upper rail. The lower tier rail 2 is preferably located intermediate the upstream section 1-1 of the upper tier rail and the return rail body 3-2. In other words, the lower rail 2 is offset from the upper rail. The movement output by the output end of the moving assembly includes a horizontal movement and a vertical movement.

If the first transfer device 5 is located at the input end side of the upstream section 1-1 of the upper layer rail, the receiving plate 7-1 stops above the output end of the lower layer rail 2 in the initial state, the opening 7-2 of the receiving plate 7-1 is opposite to the reduced diameter part of the sample holder, the reduced diameter part of the sample holder can move into the clamping groove 7-3 through the opening 7-2 along with the conveying of the lower layer rail 2, and then the sample holder moves upwards along with the moving assembly, so that the upper large diameter part 7-6 of the sample holder can be located on the sinking platform 7-5 through adaptive adjustment. Therefore, the clamping effect is formed on the sample support, and meanwhile, the limiting effect is formed on the sample support, so that the sample support can be stably located in the clamping groove 7-3. After the receiving plate 7-1 rises to a certain height above the upstream section 1-1 of the upper rail, the moving assembly drives the receiving plate 7-1 to move horizontally until the receiving plate 7-1 is positioned above the upstream section 1-1 of the upper rail, and at the moment, the bottom of the sample holder in the receiving plate 7-1 is just seated on the upstream section 1-1 of the upper rail, and the reduced diameter part is just opposite to the opening 7-2 of the receiving plate 7-1. Under the conveying action of the upstream section 1-1 of the upper rail, the sample holder slides out of the receiving plate 7-1 through the opening 7-2. Then the receiving plate 7-1 is driven by the moving assembly to return according to the original path.

If the first transfer means 5 is located at the output end side of the downstream section 1-2 of the upper track, the moving principle of the receiving plate 7-1 is similar to that of the input end side of the upstream section 1-1 of the upper track, and therefore, the description thereof will be omitted.

It should be noted that, there may be two or more card slots 7-3 in the support plate 7-1. Two or more card slots 7-3 are arranged along the moving direction of the sample holder. The adjacent two clamping grooves 7-3 are communicated through a channel 7-4. The first transfer device 5 is also illustrated on the input side of the upstream section 1-1 of the upper track: if the plate carrier is stopped above the outlet end of the lower rail 2, the first sample carrier will enter the card slot 7-3 through the opening 7-2 as the lower rail 2 is transported, and will gradually enter the innermost card slot 7-3 or the card slot 7-3 farthest from the lower rail 2 under the transporting action of the lower rail 2. Then the second and third sample holders will enter the next inner card slot 7-3 and the next inner card slot 7-3 in sequence. After the sample support is transferred to the upper part of the input end of the upstream section 1-1 of the upper-layer rail by the receiving plate 7-1, the sample support slides out of the receiving plate 7-1 in sequence under the conveying action of the upstream section 1-1 of the upper-layer rail. The arrangement of the plurality of card slots 7-3 improves the transfer efficiency.

The specific structure of the moving assembly is described next: the moving assembly comprises a horizontal moving assembly and a vertical moving assembly, the horizontal moving assembly is arranged on the horizontal base plate 5-1, and the vertical moving assembly is arranged on the vertical base plate 5-6. The vertical base plates 5-6 are connected to the output end of the horizontal moving assembly. The horizontal base plate 5-1 is arranged on the fixing frame.

The horizontal moving assembly comprises a horizontal transmission belt 5-2, a first driving wheel, a first driven wheel and a first motor 5-5. A horizontal transmission belt 5-2 is wound on the first driving wheel and the first driven wheel. The first driving wheel is driven by a first motor 5-5, and the first driving wheel, the first driven wheel and the first motor 5-5 are all arranged on the horizontal substrate 5-1. The vertical base plate 5-6 is connected to the horizontal transmission belt 5-2.

Furthermore, a horizontal guide rail 5-3 is arranged on the horizontal base plate 5-1, a horizontal sliding block is connected to the vertical base plate 5-6, and the horizontal sliding block is in sliding fit with the horizontal guide rail. Thus, the vertical base plate 5-6 can move along the horizontal guide rail 5-3 under the driving action of the horizontal transmission belt 5-2. The horizontal movement of the vertical base plates 5-6 is also the horizontal movement of the vertical movement assembly.

In order to ensure that the vertical moving component can move in place when moving horizontally, thereby ensuring the smooth proceeding of the sample support transferring operation, the utility model discloses a horizontal in-place detector 5-4 is arranged on the horizontal substrate 5-1. After the first motor 5-5 drives the vertical moving component to move horizontally, the horizontal in-place detector 5-4 detects whether the vertical moving component moves in place or not. If the horizontal to in-position detector 5-4 detects that the vertical moving assembly is moved in position, the controller controls the transfer device to perform subsequent actions. If the horizontal in-place detector 5-4 detects that the vertical moving component does not move in place, the horizontal in-place detector 5-4 triggers an alarm to give an alarm, and the transfer device suspends the operation.

For example, in the process that the receiving plate 7-1 transfers the sample of the lower rail 2 to the upstream section 1-1 of the upper rail, after the receiving plate 7-1 moves to a certain height from the lower rail 2, the first motor 5-5 controls the vertical moving assembly, or controls the receiving plate 7-1 to move in the horizontal direction. After the first motor 5-5 is driven, the horizontal-to-position detector 5-4 detects whether the vertical moving assembly, or the vertical substrate 5-6, is moved to the position. If the position is moved, the controller controls the first motor 5-5 or the second motor 5-10 to perform a subsequent action. If the vertical moving component is detected not to move in place, the first motor 5-5 and the second motor 5-10 stop working, and an alarm is triggered to give an alarm.

The vertical moving assembly comprises a vertical transmission belt, a second driving wheel, a second driven wheel and a second motor. The vertical transmission belt is wound on the second driving wheel and the second driven wheel. The second driving wheel is driven by a second motor 5-10, and the second driving wheel, the second driven wheel and the second motor are all arranged on the vertical base plate 5-6.

Furthermore, the utility model also arranges a vertical guide rail 5-7 on the vertical base plate 5-6. The supporting plate 7-1 is connected with a vertical sliding block, and the vertical sliding block is in sliding fit with the vertical guide rail 5-7. Driven by the vertical transmission belt, the supporting plate 7-1 slides up and down along the vertical guide rail 5-7.

In order to ensure that the receiving plate 7-1 can move in place when moving in the vertical direction, thereby ensuring the smooth proceeding of the sample support transferring operation, the utility model is provided with a vertical in-place detector 5-9 on the vertical base plate 5-6.
