[0011] A manual discharge and packaging system for coal sample collection in a factory, which comprises a collecting device, a sample barrel temporary storage and conveying device and a barrel holding device, wherein the sample barrel temporary storage and conveying device is used to convey an empty barrel to a feeding position, and the barrel holding device is used to convey an empty barrel 2 conveyed to the feeding position to the collecting device; The sample barrel temporary storage and conveying device comprises a conveying motor 26, which is threadedly connected to a conveying screw 23, on which a conveying slide 25 is sleeved, and the conveying slide is fixed to a sample barrel conveying long slide 24.

[0012] The manual discharge and packaging system for collecting coal samples entering the factory, the collecting device includes a collector motor 1, and the middle part of the collector motor is fixed to the rotating disk 27.

[0013] The described coal sample collection and manual discharge packaging system for entering the factory, the described bucket holding device includes a bucket holding mechanical arm lifting cylinder 11 and a bucket holding mechanical arm horizontal finger cylinder 12, and the push rod end of the described bucket holding mechanical arm lifting cylinder is fixed to the described bucket holding mechanical arm horizontal finger cylinder.

[0014] The described artificial discharge and packaging system for coal sample collection entering the factory has a lock opener 19, a signal transmitter 20, a cover opening and removing position 21 and a weighing position 22 at the turntable. The cover opening and removing position includes a cover grabbing manipulator lifting cylinder 5 and a cover grabbing manipulator horizontal finger cylinder 6. The push rod end of the cover grabbing manipulator lifting cylinder is fixed to the cover grabbing manipulator horizontal finger cylinder.

[0015] Working principle: The operator places the locked sample barrel on the barrel entry platform and starts with one button. The sample barrels are pushed to the barrel entry position one by one. The photoelectric switch detects that there is a barrel in the original position. The PLC controls the barrel push cylinder to push the sample barrel onto the sample collector plate and push it to the third position to fix it. After the six-station sample barrels are fully pushed in place, the PLC detects the incoming ore information, powers on the corresponding barrel cover, opens the corresponding barrel cover, and the barrel cover is unlocked in place. The PLC sends an unlocking signal to the PLC, and the robot grabs the corresponding barrel cover, controls the rotation of the plate, and aligns the corresponding barrel position after the cover is removed with the material receiving position.

[0016] When the current sample barrel is finished receiving materials, the large plate turns back to the capping position and automatically caps. After capping is completed, the PLC issues a locking and information storage command, the barrel lid is locked in place, and a locking signal is sent to the PLC. The PLC can then enter the next cycle of power-on, lid opening, rotation, lid grabbing, rotation, receiving materials, turning back, capping, and locking.

[0017] After all sample barrels have been loaded, when unloading, the large plate rotates to ensure that barrel No. 1 is aligned with the unloading position, and the unloading cylinder pushes the barrels onto the unloading slide, and unloads the barrels one by one. The operator directly takes out the sample barrels with the lock code on the unloading platform.

[0018] Process flow: (1) When the sampler starts working at the beginning of each shift, the collector interlocks the sampler's start signal to prepare for sampling. First, the bucket number is assigned according to the batch information and sampling code issued by the sampling plan. When the collector is ready, sampling can be reduced.

[0019] (2) When the batch information is changed, the collector receives a new sampling code. At this time, the collector will start to change the barrel number after the reduction is completed. Sampling is allowed after the change is completed. (3) When a batch of coal samples needs to be collected, a password bucket pre-designated by the system automatically rotates to the receiving station, then automatically swipes the card to unlock, automatically opens the lid, automatically collects the sample and weighs it. After the sample is collected, the lid is automatically closed and locked. Then the system automatically controls another password bucket of the coal type to be collected to enter the receiving station and repeat the above actions.

[0020] (4) When a batch of coal samples is collected or a password bucket is full (the sample weight reaches the set value), the system automatically prompts and rotates the bucket to the bucket retrieval station.

[0021] Product performance indicators: (1) The electronic lock combination barrel and barrel cover are made of stainless steel, which is durable and can be reused. The barrel cover requires an ultra-long standby time of more than 10 days and is recharged regularly. It can communicate and interconnect with PLC. It has the functions of opening and closing, fault alarm, and battery power reminder.

[0022] (2) The electronic lock is powered by a 12V power supply and adopts an intermittent power supply method. The system will only issue a power supply command after the current barrel is assigned to the sequence to be connected to the materials. At this time, the electronic lock mechanism of the barrel cover is unlocked and energized. After completing the material connection task, the internal circuit is automatically disconnected, which greatly extends the battery standby time (charged once about once a month). The electronic lock is also designed with a switch lock position signal feedback function (this technique is particularly important). Only when the switch lock is in place signal is obtained can the system execute the next operation. This avoids the common disadvantage of many manufacturers, the difficulty of picking up the barrel and the barrel cover together, and is stable and reliable.

[0023] (3) Sample information is recorded in the chip of the electronic lock barrel in an encrypted format. After the sample enters the lock barrel and is locked, it cannot be opened during transportation. Only after arriving in the sample preparation room can the coded information in the chip be read by a scanner. Only with authorization can the lock be opened by swiping a card, thus ensuring confidentiality of the samples throughout the process.

[0024] (4) During the sample collection process, the system can automatically close and lock the lid after each sub-sample is collected. On the one hand, it can ensure the confidentiality of the sample, and on the other hand, it can ensure that no water is lost during the sample collection process.

[0025] (5) Automatic unlocking and locking. Wireless transmission of lock status.

[0026] The sample barrel is locked when it is placed in the collector. Before it reaches the drop point, the sensor automatically unlocks it. After unlocking, an unlocking signal is sent. The wireless receiver receives the unlocking signal and sends a signal command to the PLC, which controls the manipulator to automatically extract the barrel cover. (The unlocking rate of the sample barrel must be 100%, otherwise the barrel will be lifted together, causing irreversible damage. At the same time, the wireless receiver receives the barrel cover unlocking signal every time to ensure the closed loop of the system).

[0027] After unlocking, the barrel cover transmits information wirelessly, and has three functions: opening, closing and fault, and communicates with the PLC in a chain manner.

[0028] After collecting the sample, the sample barrel rotates to the next position and locks automatically.

[0029] (6) The sampling process is fully enclosed, with a sealed coal drop pipe with an asbestos rubber bottom plate and a barrel mouth that is tightly pressed, without any dust leakage or water loss.

[0030] (7) The robot automatically closes and removes the lid. The curved gripper automatically locks the lid after grabbing it, and it will not loosen or fall off.

[0031] The manipulator has two types: fork type and clamp type. According to the space on site, you can also choose the precise positioning and capping system. At the same time, it can prevent extrusion and overload. It is equipped with real-time detection to check whether the barrel cover is accurately shifted.

[0032] (8) Single tank real-time weighing, V-shaped base, suspended weighing tray.

[0033] (9) The packaging system of the sampling machine realizes the function of "non-dropping" transmission of samples (that is, from the time the sample enters the sample collection barrel to the start of sample preparation, personnel cannot touch the sample during the entire process), ensuring the realization of functions such as automatic batching of incoming coal, automatic sampling, non-dropping transmission of data and samples, encrypted transmission of test data, and complete mixing of incoming coal and factory coal. The equipment has fully automatic operation conditions, meeting the functions of automatic barrel loading, automatic material receiving, automatic weighing, automatic barrel changing, automatic encrypted packaging, automatic barrel unloading, automatic identification and removal of waste barrels, etc., and has seamless connection with automobile samplers and belt samplers. It can adapt to sampling of multiple batches of incoming coal without mixing samples, and there is no human interference factor in the whole process.

[0034] (10) The fully automatic sample sorting and packaging equipment can be seamlessly connected with the sampling machines of various manufacturers, and can be modularly designed according to various complex environments on site. The overall structure of the machine should have strong applicability.

[0035] (11) The single tank weighing password barrel collector is equipped with an independent weighing mechanism at the bottom of the feed port. After the empty barrel is in place, it is automatically weighed in real time. The weighing data is uploaded directly to the factory system database without dropping to the ground. The device has the characteristics of accurate positioning, small sample moisture loss, high equipment safety, and simple and convenient maintenance.

[0036] (12) During the sample collection process, the collector obtains the batch information and sampling code, automatically assigns a barrel number and writes the sampling code into the chip memory of the password barrel cover. The sample information, including weight, coal type, sampling time, number of reductions, number of barrels of the same batch of samples, etc., can be read out through special equipment in the sample storage room and sample preparation room. The collector weighs a single barrel, and the weight of the sample in a single password barrel is written into the memory of the barrel cover. The password barrel is safe and reliable during transportation and cannot be opened by unauthorized personnel.

[0037] (13) Collector drive device: collector disc motor (220V / 380 drive motor), inlet and outlet barrel pulley drive motor (DC 220 / 380V); (14) Collector position detection device: The collector disk is positioned using a multi-point detection method, which is stable and reliable, and avoids the risk of mixed samples caused by algorithm memory; the cam motor is used for positioning, and 6 positioning switches are added to position the barrels one by one (the number of switches is configured according to the number of barrels).
