In example, directly detected by stroke of the flexible chain stroke detection sensor 13 to flexible chain 7, it in this way can be to avoid flexible chain
Journey error caused by wearing.In addition, directly being detected by the stroke to flexible chain 7, the lower electricity of precision can be used
Machine and the high-cost servo motor of gear-box substitution high-precision carry out closed-loop control, significantly reduce the cost of system.
With in the prior art based on the transportation system of guide rail compared with, the transportation system of the present embodiment not only simplifies existing rail
The complexity of road structure, also reduction equipment when using installation and maintenance can be at any time to trouble unit when equipment breaks down
Detachable maintaining is individually carried out, human cost and production cost are reduced.
As shown in Fig. 1 to 5, the liquid transportation system of matching of the full-automatic dispensing equipment in the present embodiment has following conveying side
Method specifically comprises the following steps:
(1) driving of sprocket wheel transmission mechanism 5 load bearing component 2 is moved to the lower section of pallet 4；Load bearing component 2 is in low level at this time
State, pallet 4 are in originating location, and pallet 4 is carried on the upper surface of rigid substrates 11.
(2) 3 drive sprocket transmission mechanism 5 of sprocket wheel elevating mechanism lifting upwards, so that the top salient point 10 of load bearing component 2 is from rigid
It is passed through in through slot 9 on property substrate 11 and lifts pallet from rigid substrates 11；Sprocket wheel transmission mechanism 5 is started to work, flexible chain 7
Drive moves load bearing component 2 and pallet 4 along the cloth set direction of through slot 9；
(3) 3 drive sprocket transmission mechanism 5 of sprocket wheel elevating mechanism moves downward, and pallet 4 is made to ride upon rigid substrates 11
On, so as to subsequent operation.
In addition, flexible chain 7 may be configured as on sprocket wheel 6 when it is the bagged liquid for having been injected into drug that pallet 4, which is carried,
Incomplete tensioning state, but the incomplete tensioning state refer to guarantee flexible chain 7 can normally drive load bearing component 2 move
But the state that can slightly rise and fall.At this point, the bagged liquid of drug is had been injected into when moving on pallet 4 with load bearing component 2,
Bagged liquid can be rocked, medical fluid and drug can be sufficiently mixed uniformly using the fluctuating of flexible chain 7, avoid drug without
Drug effect decline caused by method is uniform.So, the conveying mechanism in the application can also be completed while conveying medicine company bag
Its mixing step, while guaranteeing safe transport, moreover it is possible to have the function of to shake up, no longer need to that shaking up for bagged liquid is additionally arranged
Oscillation device, intensivism are strong.At this point, the top salient point 10 on load bearing component 2 is preferably ball head structure, while in the following table of pallet 4
Face offers groove compatible with ball head structure, can guarantee that pallet 4 can steady position by the matching of ball head structure and groove
It moves, avoids toppling because rising and falling.
At the same time, the present embodiment middle sprocket elevating mechanism 3 can be also used for across the chamber translation of full-automatic dispensing equipment.Tool
For body, full-automatic dispensing equipment is generally divided by function several chambers at present, and several chambers independently form, but chamber two-by-two
Between often have gap.Therefore, when encountering such case, the transportation system being respectively provided in each chamber in the present embodiment,
At this point, 3 pushing tow of sprocket wheel elevating mechanism makes the upward pushing tow pallet of load bearing component 2, the leap in gap between chamber can be completed.
During sprocket wheel transmission mechanism 5 drives load bearing component 2 to translate, flexible chain stroke detection sensor 13 detects soft
The moving distance of property chain.Detection process specifically includes the following steps: flexible chain stroke detection sensor 13 laser source array
18 issue laser, and laser sequentially passes through internode gap, optical filter 17 and the polarizing film 16 of flexible chain 7, finally exposes to flexibility
On the ccd sensor 14 of chain stroke detection sensor 13.In 7 moving process of flexible chain, flexible chain stroke detection sensor 13
Image processing unit 15 sampled every the image that predetermined period obtains ccd sensor 14, and according to each sampled result
Calculate the moving distance of flexible chain 7 in each sampling interval.
In the present embodiment, image processing unit once samples image every 40ms, between adjacent double sampling
The translation distance of image can be used as the moving distance of flexible chain 7 in current sampling interval.By the moving distance in some period
It adds up, the overall movement distance of flexible chain 7 during this period of time can be obtained.
Although above embodiments are elaborated referring to conception and embodiment of the attached drawing to the utility model aim,
But those skilled in the art will realize that still may be used in the case where no disengaging claim limits the precondition of range
To make various modifications and variations to the utility model, therefore will not repeat them here.
