Detailed Description

Embodiments of the invention are described in detail below with reference to the attached drawings, but the invention can be implemented in a number of different ways, which are defined and covered by the claims.

Referring to fig. 1-2, the preferred embodiment of the present invention provides an online laboratory comprising an endless conveyor 6000, a carrier transport vehicle 1000 placed on the endless conveyor 6000, carrier operating mechanisms distributed beside the endless conveyor 6000, and various online analyzers 3000. The carrier operating mechanism includes a carrier cleaning mechanism, a carrier handling mechanism 4000 for receiving clean carriers and weighing the carriers with samples, and an automatic sample separating mechanism 2000 for providing the carriers with coal samples. A carrier transfer cart moving mechanism 5000 for matching with the carrier cleaning mechanism and the online analyzer 3000 is also arranged beside the circulating conveyor 6000. The carrier transfer cart moving mechanism 5000 includes a bottom plate 5100 and a temporary storage table 5200 for operation of the carrier cleaning mechanism and the on-line analyzer 3000, and the temporary storage table 5200 is disposed at an interval from the bottom plate 5100. The bottom plate 5100 is provided with a blocking piece 5300 for blocking or releasing the carrier transfer cart 1000 on the endless conveyor 6000 and a lifting table 5400 for reciprocating between a blocking position and the temporary storage table 5200; the lift table 5400 is provided with a loading/unloading mechanism for loading/unloading the tool transfer cart 1000.

The lifting platform 5400 is provided with a follow-up loading and unloading mechanism matched with the carrier transfer trolley 1000, and the loading and unloading mechanism is used for placing the carrier transfer trolley 1000 at the blocking position to the temporary storage platform 5200 or placing the carrier transfer trolley 1000 on the temporary storage platform 5200 back to the blocking position.

The carrier transfer cart 1000 is placed on the endless conveyor 6000, and is driven to be transported by friction force of the endless conveyor 6000. Referring to fig. 3 and 4, the transfer body 1100 is provided with a carrier hole 1200, and a carrier can be placed or manually placed in an external mechanism such as a crucible placing device, an oxygen bomb clamping jaw, etc., and a sample such as a coal sample is contained in the carrier. When the transfer body 1100 is transported to the operation point, such as the sampling point, the baking point, corresponding positions on the endless conveyor 6000. The external lifting rod is inserted into the lifting hole 1300, and the transferring body 1100 is matched with the lifting rod to keep balance, so that the transferring body can stably rise and cannot rotate. When the crucible is lifted to the required height and reaches the operating point, the operating mechanism operates the sample in the carrier, such as the crucible X and the oxygen bomb. The transfer body 1100 can be returned to the endless conveyor 6000 by reversing the above-described operations. After the current transfer body 1100 is lifted, the subsequent transfer trolley can pass through the device unimpeded and quickly, the time interval for taking the carriers later is shortened, and the transportation efficiency is improved. The carrier hole 1200 may be a through hole or a blind hole, and when the carrier hole is a blind hole, the carrier can only adopt a corresponding clamp to take out the discarded sample from the upper part. In the case of through holes, in addition to taking out the discarded samples from above by using a clamp, the corresponding rod body can also be used for extending into the carrier hole 1200 to eject the carrier out of the discarded samples.

Alternatively, referring to fig. 3 and 4, the transfer body 1100 includes a guide groove 1310 communicating the lifting hole 1300 with the bottom surface of the transfer body 1100. Meanwhile, the guide groove 1310 can also enable the transferring body 1100 to be more stable and not easy to topple when the rod-shaped lifting rod axially moves. Optionally, the carrier hole 1200 is penetrated from top to bottom, into which the external pick-up bar 4530 extends from below to eject the carrier or from above into which the carrier is placed. Alternatively, referring to fig. 3 and 4, the transferring body 1100 is provided with an identifier, such as an identification chip, and the top surface of the transferring body 1100 is provided with a mounting area 1400 for mounting the identification chip, such as a groove for digging the identification chip on the top surface of the transferring body 1100 for embedding the identification chip, or only a blank area is flowed for attaching or otherwise fixing the identification chip. The carrier transfer vehicles 1000 are usually arranged on the circulating conveyor belt 6000, so that the degree of automation and the working efficiency are improved, the identification chip is arranged to distinguish each carrier transfer vehicle 1000, the information of the carriers can be recorded, the possibility of errors in the subsequent process is reduced, and the degree of automation and the degree of intelligence are improved. Optionally, the carrier transporter moving mechanism 5000 further includes a reading mechanism for reading the identification chip.

The carrier operation mechanism includes a carrier cleaning mechanism N, a carrier processing mechanism 4000, and an automatic sample separating mechanism 2000. The carrier cleaning mechanism is mainly used for cleaning carriers, such as crucibles and oxygen bullets of various types and specifications. The carrier processing mechanism 4000 is matched with the carrier cleaning mechanism and is responsible for carrying out preparation work before receiving the coal sample and work after receiving the coal sample on the cleaned carrier, such as moving the carrier to a weighing position and a position where the automatic sample separating mechanism 2000 releases the coal sample (the weighing position and the position where the coal sample is released are the same in general), and finally transferring the carrier with the weighed coal sample to the circulating conveyor 6000. The automatic sample separating mechanism 2000 is responsible for receiving the coal sample bottles, pouring out the coal samples in the coal sample bottles through the operations such as moving and overturning, and pouring out the coal samples into the carrier. The carrier operation mechanism mainly performs preparation such as carrier cleaning, transferring, loading, etc., and the carrier is transferred to the circulating conveyor 6000 after loading, and is tested by various online analyzers 3000. The online analyzer 3000 is configured according to the collection requirement of the coal sample data, and is generally required to test ash, volatile matters, moisture, sulfur, heat value, hydrocarbon and nitrogen elements of the coal sample, so that an ash analyzer, a volatile matter analyzer, a moisture meter, a sulfur meter 3900, a calorimeter 3700 and an element analyzer 3800 are required to be configured.

Referring to fig. 5 and 6, each of the online analyzers 3000 tests a carrier-transfer-vehicle moving mechanism 5000 in one-to-one correspondence. The blocking element 5300 forms a blocking for the carrier vehicle 1000 near the endless conveyor belt 6000, and the carrier vehicle 1000 at the current position stops moving so that the first push-pull mechanism 5410 and the lifting rod 5420 are matched and taken away, and the rest carrier vehicle 1000 still moves. After the carrier transport vehicle 1000 is removed, the blocking member 5300 is away from the endless conveyor 6000, and the carrier transport vehicle 1000 can travel unimpeded along with the endless conveyor 6000.

The loading and unloading mechanism takes the carrier transport vehicle 1000 in the blocking position, the lifting platform 5400 is lifted or lowered to a position suitable for operating the temporary storage platform 5200, and then the carrier transport vehicle 1000 is placed on the temporary storage platform 5200. The on-line analyzer 3000 takes away the carriers in the carrier transport vehicle 1000 placed on the temporary storage table 5200, performs corresponding processing and testing, and returns to the carrier transport vehicle 1000. After the loading and unloading mechanism finishes sampling, the carrier transfer vehicle 1000 is put back to the blocking position on the circulating conveyor belt 6000. The carrier transfer cart 1000 is put back onto the endless conveyor 6000, and when the carrier transfer cart arrives at the carrier cleaning mechanism following the advancing movement, the carrier is cleaned by the carrier cleaning mechanism, so that the carrier is repeatedly recycled.

Preferably, referring to fig. 1 and 2, the on-line laboratory is further provided with a manual operation table 9000, after loading the carbon-hydrogen nitrogen and heat-generating quantity test coal sample, the carrier transfer vehicle 1000 reaches the position of the manual operation table 9000 first, and the carrier transfer vehicle moving mechanism 5000 or the crucible is manually taken to the manual operation table 9000 to perform operations of manually rubbing balls, placing the crucible into an oxygen bomb and loading ignition wires, and then returning to the circulating conveyor belt 6000. The coal sample and related operation manual operation efficiency is high, and the finished quality is good. After the calorimeter 3700 is tested, the sample is transferred to the manual operation table 9000, and an oxygen bomb is opened manually to clean the crucible.

In the above-mentioned online laboratory, the carrier processing mechanism 4000 receives the weighing of the clean carrier, and adds the sample of the required weight to the carrier in cooperation with the automatic sample dividing mechanism 2000, so as to transfer the carrier to the carrier transfer vehicle 1000. The carrier transfer trolley 1000 moves on the circulating conveyor 6000, and according to the analysis data, the carrier transfer trolley moving mechanism 5000 takes the carrier transfer trolley 1000 to the temporary storage platform 5200 for subsequent analysis processing of the corresponding online analyzer 3000, and after the analysis is completed, the temporary storage platform 5200 returns to the circulating conveyor 6000. The carrier cleaning mechanism takes away the carriers of the carrier transport vehicle 1000 to clean and provide to the carrier handling mechanism 4000. When the carrier transfer trolley 1000 is taken, the carrier transfer trolley 1000 is blocked by the blocking piece 5300 approaching the circulating conveyor 6000, and the carrier transfer trolley 1000 at the blocking position is taken away by the loading and unloading mechanism and matched with the lifting platform 5400 to be sent to the temporary storage platform 5200 for sampling analysis by the on-line analyzer 3000. After the sampling is completed, the carrier transport vehicle 1000 is returned to the endless conveyor 6000. The whole operation process of the circulating conveyor belt 6000 does not need to stop, so that the power mechanism of the circulating conveyor belt 6000 is not damaged, and meanwhile, the circulating conveyor belt 6000 runs uninterruptedly, and the conveying efficiency is improved. Above-mentioned online laboratory, the washing of carrier, transfer, application of sample are the instrument completion, and degree of automation is high, and detection efficiency is high.

The second push-pull mechanism 5510 is provided corresponding to the temporary storage stage 5200 for loading and unloading the temporary storage stage 5200 with the tool carriage. The second push-pull mechanism 5510 pushes the carrier transport cart 1000 on the lift bar 5420 onto the staging platform 5200 and pulls the carrier transport cart 1000 back to the lift bar 5420.

The carrier transport vehicle 1000 is stopped by the blocking element 5300 and the first push-pull mechanism 5410 pushes the lift bar 5420 into the lift hole 1300. The first push-pull mechanism 5410 may be a cylinder mechanism, a motor-driven propulsion mechanism, or other mechanism having a linear reciprocating propulsion function. Then the lifting platform 5400 is lifted or lowered to the level with the temporary storage platform 5200, and the second push-pull mechanism 5510 pushes the carrier transfer trolley 1000 on the lifting rod to the temporary storage platform 5200 for sampling analysis by the on-line analyzer 3000.

The multi-carrier transfer mechanism receives the carriers taken from the carrier storage and transportation mechanism 4200 by the carrier placement mechanism 4300, and revolves through the weighing mechanism 4600 and the carrier taking mechanism 4500 in sequence to complete the corresponding operations. The multi-carrier transfer mechanism includes a base 4100, where the base 4100 includes a corresponding carrier position a, a carrier position C, and a carrier position D. The housing 4100 is provided with a revolution main shaft 4110 rotating relative to the housing 4100 and a plurality of rotating disk groups 4120 which are provided uniformly around the revolution main shaft 4110 to follow revolution and switch at each station.

Referring to fig. 14, the multi-carrier transfer mechanism is peripherally surrounded by a placement carrier mechanism, a weighing mechanism 4600, and a pick carrier mechanism 4500. The rotating disk assembly 4120 may house various types of carriers. The following describes the multi-type carrier transfer mechanism using the carrier as a crucible, and the specific processing procedures of the other types of carriers are basically the same. Different crucibles are handled by different sets of rotating disks 4120, each rotating disk 4123 holding the same crucible. The placement hole sizes of the respective rotary disks 4123 are different, or the placement hole sizes of some of the rotary disks 4123 are different. The number of placement holes of each rotating disk 4123 is preferably an even number, so that two crucibles can be placed at a time, thereby improving the working efficiency. The rotating disk 4123 is preferably removably attached, and the rotating disk 4123 can be installed and replaced as needed to accommodate the needs of various crucibles.

And the number of the rotating disc groups 4120 can be consistent with or greater than the number of operators, for example, the stations comprise a loading position, a weighing position and a taking position, and the number of the rotating disc groups 4120 can be 3 groups, 4 groups or more. When the number of the rotating disc groups 4120 is greater than the number of operators, the position of the seat 4100 not corresponding to the operation mechanism is the transition position B. The rotating disc groups 4120 are uniformly distributed, and the revolving angle of each revolution is used for ensuring that each rotating disc group 4120 can pass through the operation station. As shown in fig. 14, the revolution angle may be 90 °.

Obviously, the driving device control connecting rod 4122 can be arranged on the corresponding station of the seat 4100 to drive the rotating disk 4123 to rotate, and the mode has the advantage of lower cost. In the former way, a driving device needs to be disposed on each connecting frame 4121, so that the cost is high, and in some steps, as in the previous transition position, no corresponding operating mechanism is used for operating the crucible, the rotating disc 4123 can not rotate, and the arrangement of the driving device on the connecting frame 4121 may cause energy waste due to the fact that the rotation is also performed in the transition position. The corresponding stations of the seat 4100 are provided with driving devices, the number of the driving devices is small, the cost is low, and the rotating disk 4123 does not rotate when the rotating disk does not need to rotate.

When the rotating disc group 4120 reaches each station, the rotating disc 4123 makes all the carriers loaded by the rotating disc group complete the operation of the station through autorotation. Taking the rotary disk set 4120 for carrying the carrier, the operation of the rest of the stations is similar. The carrier placement mechanism 4300 rotates the rotating disk 4123 to rotate the empty placement hole to the crucible placement point each time 1 or two crucibles are placed, and finally fills the crucible on the rotating disk 4123.

And when this rotary disk 4123 is performing the crucible discharging operation, the weighing mechanism 4600 and the pick-up carrier mechanism 4500 are also operating on the rotary disk 4123 that stays at their corresponding stations. It will be appreciated that the number of holes in each rotating disc 4123 is preferably equal, so that the operations of each rotating disc 4123 at different stations can be guaranteed to be completed substantially simultaneously, and the waiting time for completing the operation of the rotating disc 4123 at one station but not rotating to the next station due to incomplete operations of the rotating discs 4123 at other stations is shortened, thereby improving the working efficiency.

The multi-type carrier transfer mechanism includes a revolving spindle 4110 and a rotating disc set 4120, and a plurality of rotating disc sets 4120 can accommodate a plurality of types of carriers. The rotating disk set 4120 sequentially passes through a carrier placing position, a carrier weighing position and a carrier taking position along with the revolution spindle 4110. When the rotating disc 4120 reaches each station, the rotating disc 4123 rotates to enable all the loaded carriers to finish the operation of the station, and then revolves to the next station to finish the operations of weighing and taking the carriers. The multi-type carrier transferring mechanism can process multiple types of carriers simultaneously, the carriers at each station are operated at the corresponding stations simultaneously, the carriers are subjected to seamless conversion among the placing, weighing and taking processes, the automation degree is high, and the processing efficiency is high.

The mass of the first arm is larger than that of the second arm, so that the first arm is attached to the sliding block in a natural state without external force, and the second arm is vertical. In this state, the slider is pressed against the first arm, and the rotating pawl 4132 can rotate only in the direction of the second arm. When the rotating claw cylinder 4131 pushes the rotating claw 4132 to protrude rightward, the second arm outer wall surface is brought into contact with the touch lever 4133 during traveling, pushing it to rotate, thereby driving the rotating disk 4123 to rotate, which is a push state. When the rotating claw cylinder 4131 drives the rotating claw 4132 to retract to the left, the outer wall surface of the second arm is contacted with the touching rod 4133 during the traveling process, the second arm rotates anticlockwise under the reaction force of the touching rod 4133, the height of the rotating claw 4132 is reduced so as to avoid the touching rod 4133 and avoid continuous contact, and after the rotating claw 4132 is thoroughly separated from the touching rod 4133, the rotating claw 4132 returns to the second arm standing state, and the rotating disc 4123 keeps in the static state during the traveling process, so that the rotating disc 4123 is in the avoiding state. The toggle mechanism 4130 with the design is simple in structure, and can not prevent the rotating disc group 4120 from being blocked when the rotating disc 4123 revolves around the revolution, and the rotating disc 4123 enters and leaves the toggle mechanism 4130 conveniently and rapidly.

Alternatively, referring to fig. 13, each rotating disk 4123 is mounted at a height compatible with the carriers being loaded so that the bottom heights of all carriers are equal. The support seat 4141 fixed on the base 4100 is arranged outside the revolution main shaft 4110 in a penetrating manner, each connecting frame 4121 is arranged in a sliding manner along the axial direction of the revolution main shaft 4110, the bottom of each connecting frame 4121 is propped against the support seat 4141 and revolves along the circumferential direction of the support seat, the support seat 4141 is provided with a notch 4142 at the carrier weighing position, and the base 4100 is provided with a lifting device for lifting the connecting frame 4121 at the carrier weighing position at the position corresponding to the notch 4142 so as to enable the carrier to be in contact with the weighing mechanism 4600 for weighing.

The support base 4141 is fixedly connected to the base 4100 so as not to follow the revolution. Each connecting frame 4121 is axially slidably connected to the revolution main shaft 4110 by a slide rail and slider fit. The connection frame 4121 rotates following the revolution main shaft 4110 while the bottom is pressed against the support base 4141 to be supported thereby at the time of revolution, so that the connection frame 4121 is in a stable equilibrium state in a normal state and does not naturally slide down. When the rotational frame 2120 passes through the notch 4142, the connecting frame 4121 is separated from the supporting base 4141 and supported by the lifting device instead. After the lifting device descends to enable the crucible to be in contact with the weighing rod of the weighing mechanism 4600 to finish weighing, the crucible is lifted and reset, the rotating disc 4123 rotates to convert the other crucible to a weighing position, the weighing is descended, the cycle is repeated until all the crucibles are weighed, and the rotating disc 4123 is lifted and reset to leave the notch 4142 along with revolution and is supported by the supporting seat 4141 again. The whole device is small in size due to the design, the weighing process is stable in operation, and the operation difficulty is low. The lifting device can be a screw rod transmission structure, a linear guide rail transmission mechanism, an air cylinder transmission mechanism and a conveyor belt transmission mechanism.

Alternatively, referring to fig. 12, the bottom of the connecting frame 4121 is abutted against the supporting seat 4141 by the rolling bearing 4143. The lifting device comprises a transition support member 4145 which is driven by a motor to lift the lifting cam 4144, wherein a lifting bearing 4146 which replaces the rolling bearing 4143 to lift the lower edge of the connecting frame 4121 is arranged at the top of the transition support member 4145.

The bottom of the connecting frame 4121 is connected with the supporting seat 4141 through the rolling bearing 4143, and the rolling is smooth and the resistance is small during revolution. The top of the transition support 4145 is provided with a lifting bearing 4146, when the rolling bearing 4143 of the connecting member reaches the notch 4142, the lifting bearing 4146 comes into contact with the lower edge of the connecting member, the contact surface between the rolling bearing 4143 and the connecting member gradually increases as the rolling bearing 4143 is added into the notch 4142, and the contact surface between the rolling bearing 4143 and the connecting member gradually decreases. When the rolling bearing 4143 completely enters the notch 4142, the rolling bearing 4143 is completely separated from the connecting member and supported by the lifting bearing 4146. At this time, the height of the connector remains unchanged so that the connector is supported by the support 4141 after the connector is separated from the notch 4142 by revolution after the weighing is completed. Because the lifting height precision of the lifting device is not excessively high during weighing, the lifting device in the embodiment lifts the connecting piece through the height difference generated by the rolling of the lifting cam 4144, so that the lifting requirement is met, and compared with other lifting modes, the lifting device is simple in structure, low in cost and good in reliability.

Alternatively, referring to fig. 14, the housing 4100 also has a transition B, and the side wall of the rotating disk 4123 is provided with an opening communicating with the placement hole.

The number of the rotating disc groups 4120 is larger than the number of operators, and the position of the seat 4100, which does not correspond to the operation mechanism, is the transition position. When the rotary disk 4123 is rotated to this position, the crucible is not weighed or taken away. The number of transition bits, namely the rotating disc groups 4120, is larger, so that the number of the placed crucibles can be increased, and the balance of the whole device is better. The placement holes are in communication with the side walls of the rotating disk 4123, and the manner in which the crucible is placed and removed is more varied, either by clamping or by removing the crucible from the side through the take-off lever 4530.

Alternatively, referring to fig. 14, 16 and 17, the carrier storage and transportation mechanism 4200 includes a storage and transportation housing and a translation mechanism 4230 disposed at the bottom of the storage and transportation housing, wherein a storage tray 4210 for placing various carriers and/or carrier covers in rows is disposed in the storage and transportation housing, a conveyor belt 4220 disposed at the bottom of the storage tray 4210 for driving the carriers or carrier covers to travel along the extending direction of each row is disposed in the storage and transportation housing, and the translation mechanism 4230 drives the storage and transportation housing to translate along the vertical direction of each row, so as to provide the carrier placement mechanism 4300 with the required carriers or carrier covers.

The volatile crucible has a crucible cover. The storage tray 4210 is divided into a plurality of columns by partition plates, and each column is provided with a crucible or a crucible cover of the same type, so that the crucible and the crucible cover can be stored in a classified manner. The bottoms of the crucible and the crucible cover are brought into contact with the conveyor 4220, and driven by the conveyor to travel along the extending direction of each row, and are automatically supplied to the crucible taking point of the carrier placement mechanism 4300. The translation mechanism 4230 drives the storage and transportation housing to translate along the vertical direction of each row, such that the carrier placement mechanism 4300 corresponds to a different row, thereby requiring a carrier or carrier cover.

Optionally, a bead is provided within the storage tray 4210 to prevent stacking of the carrier covers.

Because the crucible covers are thinner, when the crucible covers advance along the row direction, the rear crucible covers are easily stacked on the front crucible covers, and the crucible covers are blocked, so that the edges of each row of partition plates are provided with pressing strips to prevent the crucible covers from being stacked.

Alternatively, referring to fig. 16, the carrier placement mechanism 4300 includes a suction-discharge carrier horizontal mechanism 4310, a suction-discharge carrier vertical mechanism 4320 provided at a movable end of the suction-discharge carrier horizontal mechanism 4310, and a pick-and-place mechanism 4330 for picking and placing a carrier or a carrier cover provided at a movable end of the suction-discharge carrier vertical mechanism 4320.
