Description

Technical Field

[0001] The invention relates to a blanking and unloading box device, in particular to a side-sliding cleaning anti-straight-fall string tube used in conjunction with an intelligent Chinese medicine cabinet. Background Art

[0002] Traditional Chinese medicine is profound and extensive. Chinese medicine prescriptions are usually only targeted at specific patients and diseases. The effects of the same medicine in different prescriptions vary greatly. The traditional important drug dispensing process is: prescription writing, prescription review, drug picking and preparation, proofreading, and drug distribution. At present, almost all Chinese medicine pharmacies retain the traditional manual preparation method, and important cabinets usually store hundreds of Chinese medicinal materials, which are stored in thousands of medicine boxes. This makes the drug picking process of Chinese medicine pharmacists very time-consuming, laborious and prone to errors.

[0003] Workers at traditional Chinese medicine hospitals have made some useful explorations in the intelligentization of Chinese medicine cabinets, such as "An intelligent Chinese medicine cabinet for traditional Chinese medicine" (CN215382438): the bottom of the Chinese medicine cabinet is a medicine cabinet, and the upper part is a medicine storage cabinet. The medicine storage cabinet is divided into several medicine boxes by baffles. The inside of the medicine cabinet is slidably connected to the medicine box, and the medicine box is equipped with a liquid crystal display to display patient information and prescription information, making it easier to get medicine.

[0004] Another example is the "Intelligent Chinese Medicine Cabinet Based on PLC Control" (CN215776883): by setting a PLC module on the Chinese medicine cabinet, the PLC module controls the corresponding medicine cabinet's medicine dispenser indicator to turn on according to the prescription, making it convenient for Chinese medicine pharmacists to adjust and dispense medicines.

[0005] The above patent document is an improvement only for the manual dispensing and preparation process, and is not suitable for the dispensing and picking of medicines mainly based on bulk medicinal materials and / or mainly based on medicinal materials in small packaging bags through the combination of different unit medicine cabinets.

[0006] In the intelligent Chinese medicine cabinet, Chinese herbal medicine pieces are crushed by a stirring device, measured by a metering device, and then sent out through a belt conveyor installed in the medicine cabinet. In the same drop-out channel, multiple layers of conveyor belts are usually arranged from bottom to top. When Chinese herbal medicine pieces are sent out from a high conveyor belt, a string barrel drop channel is generally used, that is, Chinese herbal medicine pieces sent out by multiple conveyor belts are discharged to the loading tray below through the string barrel. The above string barrel has the following defects: First, Chinese herbal medicine pieces fall straight down in the string barrel, causing splashing, which is not conducive to the collection of Chinese herbal medicine pieces by the loading tray. Second, dust is easily adhered to the inner wall of the string barrel during use, which will cause the same prescription to mix with the drug dust of the previous prescription. Third, the dust adhered to the inner wall of the string barrel is not easy to clean. Summary of the invention

[0007] The purpose of the present invention is to provide a side-sliding cleaning anti-straight-fall string barrel, which aims to provide two material dropping channels in a set of string barrels, one channel is working and the other channel is self-cleaning, and the Chinese herbal medicine pieces slide down in the string barrel in a broken line form under deceleration and have a self-cleaning function.

[0009] The broken-line string barrel box is composed of at least one standard side-sliding anti-straight-fall string barrel section and one bottom-level side-sliding anti-straight-fall string barrel section, and is divided into a right drop channel and a left drop channel by a middle partition; the standard side-sliding anti-straight-fall string barrel section is composed of a left oblique downward square barrel body and a right oblique downward square barrel body with the same inclination angle connected end to end, the vertical opening of the upper front side wall of the left oblique downward square barrel body is used as a material taking port, which is used to connect with the third-level conveyor belt to take materials, the upper opening of the rear side wall of the left oblique downward square barrel body is used as a spare feeding port, the bent plate-shaped section cover is fixed to the horizontal top plate of the left oblique downward square barrel body by screws and covers the spare feeding port, and the oblique opening at the bottom of the right oblique downward square barrel body is used as a discharge port; the bottom-level side-sliding anti-straight-fall string barrel The section is composed of another left-slanting downward square cylinder and another right-slanting downward square cylinder with the same inclination angle connected end to end, the vertical opening of the upper front side wall of the other left-slanting downward square cylinder serves as an upper material taking port, which is used to connect with the second-layer conveyor belt to take materials, the upper opening of the rear side wall of the other left-slanting downward square cylinder is connected to the discharge port of the right-slanting downward square cylinder of the above-mentioned standard side-sliding anti-straight-fall string cylinder section through a sealing ring or welding, the lower vertical opening of the other right-slanting downward square cylinder serves as a lower material taking port, which is used to connect with the first-layer conveyor belt to take materials, and the horizontal opening at the bottom of the other right-slanting downward square cylinder serves as a discharge port, the bracket is vertically fixed between the other left-slanting downward square cylinder and the other right-slanting downward square cylinder, and the screw nut is fixed on the bracket;

[0010] A left standard dust box and a left bottom dust box, which are similar in shape to the left oblique downward square cylinder and the right oblique downward square cylinder in side view, are fixed to the front of the frame through L-shaped fixing parts and are located on the left side of the first, second and third conveyor belts; a right standard dust box and a right bottom dust box, which are similar in shape to another left oblique downward square cylinder and another right oblique downward square cylinder in side view, are fixed to the front of the frame through L-shaped fixing parts and are located on the right side of the first, second and third conveyor belts; a dust collector is connected to the left standard dust box, the right standard dust box, the left bottom dust box and the right bottom dust box through a pipe with a switch valve;

[0012] Compared with the prior art, the present invention has the following technical features and advantages:

[0013] 1. Slow down and prevent splashing: The side-sliding anti-straight-fall string barrel provides a falling environment that can slow down the falling of materials and prevent the splashing of medicinal materials that fall into the loading tray. Due to the zigzag structure of the side-sliding anti-straight-fall string barrel section, the medicinal materials slide down along the lower folding plate of the inner and outer folding plates in the side-sliding anti-straight-fall string barrel section, so that the medicinal materials slide down in a zigzag manner and slow down into the loading tray received by the lower end outlet. Since the sliding speed of the medicinal materials is reduced, the falling force is greatly reduced when falling into the loading tray, thereby reducing the rebound force of the medicinal materials falling into the loading tray, which plays a better role in splashing prevention.

[0014] 2. Self-cleaning function: The side-sliding anti-straight-fall string barrel device can, under the control of the control circuit board, collect the dust attached to the inner wall of the side-sliding anti-straight-fall string barrel section and the dust in the cavity through the dust suction box, and collect the absorbed dust into the dust suction and dust collection equipment through the dust suction channel formed by the dust suction box and the dust suction pipe, so as to facilitate regular cleaning.

[0015] 3. Easy operation: The equipment has a simple structure and is easy to operate, reducing the trouble of manual cleaning.

[0016] 4. Easy maintenance: Since the side-sliding anti-straight-fall string barrel adopts a modular design, whichever one fails can be replaced. The replaced side-sliding anti-straight-fall string barrel can be repaired in the maintenance workshop, minimizing the impact of maintenance on equipment operation and achieving simple and quick maintenance.

[0053] composition:

[0054] The side-sliding cleaning string barrel is composed of dust suction and collection equipment, dust suction pipes, electric control pipe switch valves, dust suction boxes, L-shaped mounting fixtures of dust suction boxes, side-sliding anti-straight-fall string barrel sections, string barrel section covers, slide rails and slide rail brackets, screw rods, reduction motors, limit switches, control circuit boards, control circuit board boxes, etc.

[0055] Each component and its function:

[0056] 1. Dust suction and dust collection equipment: Dust suction and dust collection equipment is a mature outsourced equipment, which is installed on the outside of the side-sliding cleaning anti-straight-fall string barrel device. It provides strong suction for the side-sliding cleaning anti-straight-fall string barrel device and collects the absorbed dust. It is connected to the cleaning string barrel section through the dust suction main pipe and the telescopic trolley hose.

[0057] 2. Dust collection pipe: One end of the dust collection main pipe is connected to the dust collection equipment, and the other end is connected to the dust collection box through the branch pipe. Its function is to transmit the suction force of the dust collection equipment and disperse the suction force of the dust collection equipment to each dust collection box through the branch pipe. It is also the channel for the dust collection equipment to collect dust.

[0058] 3. Electric-controlled pipeline switching valve: The electric-controlled pipeline switching valve is installed on the dust suction main pipeline, and its function is: when the left or right side of the side-sliding anti-straight fall string barrel section needs to start dust suction operation, the electric-controlled pipeline switching valve on this side opens the valve under the control of the control circuit board, so that this side of the side-sliding anti-straight fall string barrel section can be cleaned under negative pressure suction; when the left or right side of the side-sliding anti-straight fall string barrel section needs blanking operation, the electric-controlled pipeline switching valve closes the valve on this side under the control of the control circuit board, and this side of the side-sliding anti-straight fall string barrel section can be blanked under normal air pressure.

[0059] 4. Dust box: The dust box is divided into a left dust box and a right dust box. The left and right dust boxes are symmetrically installed on the L-shaped mounting fixture of the dust box, and then the L-shaped mounting fixture of the dust box is installed and fixed on the frame. The dust box is divided into a bottom section dust box and a standard section dust box corresponding to the side-sliding anti-straight-fall string barrel section. The surrounding of the dust box and the side facing the inner cavity of the string barrel section are densely covered with small dust suction holes, and the side facing the inner cavity of the string barrel section is connected to the dust suction pipe. When the suction force of the dust collection equipment is transmitted to the dust box, the internal space of the dust box forms a negative pressure suction force, which sucks the air and dust in the string barrel section into the dust box, and then transmits it to the dust collection equipment through the dust suction pipe.

[0060] 5. L-shaped dust box mounting fixture: The function of the L-shaped dust box mounting fixture is to install and fix each section of the dust box on the frame.

[0061] 6. Side-sliding anti-straight-fall string barrel section: The side-sliding anti-straight-fall string barrel section is composed of a partition in the string barrel section that separates the folded-line string barrel box vertically from the middle, forming two symmetrical folded-line string barrel boxes that are put together. The folded-line string barrel box is designed with enough space to meet the sliding of medicinal materials and decoction pieces inside it; due to the isolation of the partition in the string barrel section, the two symmetrical folded-line string barrel boxes that are put together can act independently without affecting each other.

[0062] The side-sliding anti-straight fall string barrel sections are divided into three types: bottom-level side-sliding anti-straight fall string barrel sections, standard side-sliding anti-straight fall string barrel sections, and standard side-sliding anti-straight fall string barrel sections with push. The bottom-level side-sliding anti-straight fall string barrel sections are installed at the very bottom, and the standard side-sliding anti-straight fall string barrel sections are installed alternately with the standard side-sliding anti-straight fall string barrel sections with push starting from the bottom-level side-sliding anti-straight fall string barrel sections upwards, namely: bottom-level side-sliding anti-straight fall string barrel sections → standard side-sliding anti-straight fall string barrel sections → standard side-sliding anti-straight fall string barrel sections with push → standard side-sliding anti-straight fall string barrel sections → standard side-sliding anti-straight fall string barrel sections with push... Its function is: through the specific zigzag structure design, the medicinal pieces can decelerate and slide down along the zigzag trajectory after falling into the stringing tube section, so as to prevent the medicinal pieces from raising too much dust in the stringing tube box; prevent the medicinal pieces from splashing too much when falling into the loading tray; reduce the noise caused by the medicinal pieces in the falling process; and make the side sliding push smoother.

[0063] The lower and upper parts of the bottom side-sliding anti-straight-fall string barrel section and the standard side-sliding anti-straight-fall string barrel section with pusher and the upper part of the standard side-sliding anti-straight-fall string barrel section are installed with sliders, which are used in conjunction with the slide rails installed on the rack to enable the side-sliding anti-straight-fall string barrel section to slide left and right on the rack. Calculated from the bottom side-sliding anti-straight-fall string barrel section upwards, the side-sliding anti-straight-fall string barrel sections of the odd-numbered layers separated by each layer of side-sliding anti-straight-fall string barrel section are all installed with sliders on the upper and lower parts, such as: a single-layer side-sliding anti-straight-fall string barrel section (i.e., the bottom side-sliding anti-straight-fall string barrel section), a three-layer side-sliding anti-straight-fall string barrel section, a five-layer side-sliding anti-straight-fall string barrel section, etc.

[0064] The lower and upper parts of the bottom side-sliding anti-straight-fall string barrel section and the standard side-sliding anti-straight-fall string barrel section with push are both equipped with side-sliding anti-straight-fall string barrel sections with sliding blocks. A screw nut fixing bracket is installed and fixed in the middle, and a screw nut is installed and fixed on the screw nut fixing bracket. Its function is to be used in conjunction with the screw to push the side-sliding anti-straight-fall string barrel to move left and right.

[0065] 7. String barrel section cover: The string barrel section cover is installed on the top of the uppermost side-sliding anti-straight-fall string barrel section to prevent dust and other impurities from entering the string barrel section from the top.

[0066] 8. Slide rails and slide rail brackets: The slide rails are installed on the slide rail brackets, and the slide rail brackets are installed and fixed on the rack. They are used in conjunction with the sliders installed on the side-sliding anti-straight-fall string barrel sections to enable the side-sliding anti-straight-fall string barrel sections to slide left and right on the rack.

[0067] 9. Screw: One end of the screw is fixed on the output shaft of the reduction motor through a coupling, and the other end is installed in the bearing in the bearing sleeve of the screw fixing seat. Its function is to push the side-sliding anti-straight-fall string cylinder to move left and right.

[0068] 10. Reducer motor: The reducer motor is installed on the frame through the motor seat, and the output shaft of the reducer motor is connected and fixed with the screw through the coupling. Its function is to provide power for the rotation of the screw.

[0069] 11. Limit switch: It is installed at both ends of the slide rail bracket near the screw rod. Through cooperation with the limit baffles on both sides of the side-sliding anti-straight-fall string barrel section, the information that the side-sliding anti-straight-fall string barrel section has reached the side-sliding position is sent to the control circuit board in real time. The control circuit board controls the reduction motor to stop rotating to realize the side-sliding limit of the side-sliding anti-straight-fall string barrel section.

[0070] 12. Control circuit board: The control circuit board is installed in the control circuit board box on the rack near the side of the side-sliding anti-straight-fall string tube device. Its functions are: receiving instructions from the upper computer system; receiving information transmitted by the limit switch; controlling the rotation direction and rotation of the reduction motor in the side-sliding anti-straight-fall string tube device; controlling the opening and closing of the electric control pipeline switch valve on the dust collection and dust collection equipment; reporting the operating status of the side-sliding anti-straight-fall string tube device to the upper computer system; reporting fault alarms to the upper computer system. It is the control brain of the entire side-sliding anti-straight-fall string tube device.

[0071] 13. Control circuit board box: The control circuit board box is installed on the rack adjacent to the side of the side-sliding anti-straight-fall string tube device, and plays the role of protecting the control circuit board.

[0072] Working principle:

[0073] 1. Equipment combination mode: The side-sliding anti-straight-fall string barrel section can work individually or be assembled from bottom to top in the order of bottom-level side-sliding anti-straight-fall string barrel section → standard side-sliding anti-straight-fall string barrel section → standard side-sliding anti-straight-fall string barrel section with pusher to form a complete, standard side-sliding anti-straight-fall string barrel device.

[0075] 3. Equipment operation process:

[0076] ⑴. Right side drop: The medicine cabinet conveyor belt conveys the medicinal pieces into the right side drop channel of the side-sliding anti-straight-fall string barrel. The medicinal pieces slide down along the lower wall of the string barrel box in the right side drop channel of the side-sliding anti-straight-fall string barrel. Due to the zigzag structure of the string barrel section, the medicinal pieces slow down and slide down in a zigzag manner into the loading tray received by the lower end outlet. The sliding process is as follows:

[0077] A complete and standard side-sliding anti-straight-fall stringing device involves an upper conveyor belt, two middle conveyor belts and a bottom conveyor belt. Here, only the upper conveyor belt, an upper middle conveyor belt and the bottom conveyor belt are described.

[0078] The upper conveyor belt delivers the medicinal material slices down the process: the upper conveyor belt delivers the medicinal material slices into the right side material taking port of the belt push standard side sliding anti-straight falling string barrel section and enters the right side material dropping channel. The medicinal material slices slide down along the upper folding plate of the inner folding plate of the right side material dropping channel of the belt push standard side sliding anti-straight falling string barrel section. After the medicinal material slices slide down to the upper folding plate of the inner folding plate that is separated from the right side material dropping channel, they fall in a parabolic manner to the lower folding plate of the outer folding plate of the right side material dropping channel of the belt push standard side sliding anti-straight falling string barrel section. ; The medicinal pieces continue to slide down on the lower folding plate of the outer folding plate of the right side blanking channel of the standard side-sliding anti-straight-fall string barrel section with push, and after the medicinal pieces slide down to the lower folding plate of the outer folding plate of the right side blanking channel of the standard side-sliding anti-straight-fall string barrel section with push, they fall in a parabolic manner to the upper folding plate of the inner folding plate of the right side blanking channel of the standard side-sliding anti-straight-fall string barrel section; The medicinal pieces slide down along the upper folding plate of the inner folding plate of the right side blanking channel of the standard side-sliding anti-straight-fall string barrel section, and the medicinal pieces slide down to the lower folding plate of the outer folding plate of the right side blanking channel of the standard side-sliding anti-straight-fall string barrel section. After the upper folding plate of the inner folding plate of the material channel, it falls in a parabolic manner to the lower folding plate of the outer folding plate of the right side material channel of the standard side-sliding anti-straight-fall string barrel section; the medicinal material pieces continue to slide down on the lower folding plate of the outer folding plate of the right side material channel of the standard side-sliding anti-straight-fall string barrel section, and after the medicinal material pieces slide down to the lower folding plate of the outer folding plate that is separated from the right side material channel of the standard side-sliding anti-straight-fall string barrel section, they fall in a parabolic manner to the upper folding plate of the inner folding plate of the bottom side-sliding anti-straight-fall string barrel section; the medicinal material pieces fall along the bottom side The upper folding plate of the inner folding plate of the right side of the drop channel of the sliding anti-straight-fall string barrel section slides down, and the medicinal material pieces slide down to the upper folding plate of the inner folding plate that is separated from the right side of the drop channel, and then fall to the lower folding plate of the outer folding plate of the right side of the drop channel of the bottom side sliding anti-straight-fall string barrel section in a parabolic manner; the medicinal material pieces slide down along the lower folding plate of the outer folding plate of the right side of the drop channel of the bottom side sliding anti-straight-fall string barrel section, and the medicinal material pieces slide down to the lower folding plate of the outer folding plate that is separated from the right side of the drop channel, and then fall to the lower loading tray in a parabolic manner. At this point, the sliding process of the medicinal material pieces delivered by the upper conveyor belt is completed.

[0079] The upper middle conveyor belt delivers the medicinal material slices in the sliding process: the upper middle conveyor belt delivers the medicinal material slices into the right feeding port of the standard side-sliding anti-straight-fall string barrel section and enters the right feeding channel. The medicinal material slices slide down along the upper folding plate of the inner folding plate of the right feeding channel of the standard side-sliding anti-straight-fall string barrel section. After the medicinal material slices slide down to the upper folding plate of the inner folding plate that is separated from the right feeding channel, they fall in a parabolic manner to the lower folding plate of the outer folding plate of the right feeding channel of the standard side-sliding anti-straight-fall string barrel section. The medicinal material slices continue to slide down on the lower folding plate of the outer folding plate of the right feeding channel of the standard side-sliding anti-straight-fall string barrel section. The medicinal material slices slide down to the upper folding plate of the inner folding plate that is separated from the right feeding channel. After the lower folding plate of the outer folding plate of the right side of the drop channel of the section, it falls in a parabolic manner to the upper folding plate of the inner folding plate of the bottom side-sliding anti-straight-fall string barrel section; the medicinal pieces slide down along the upper folding plate of the inner folding plate of the right side of the drop channel of the bottom side-sliding anti-straight-fall string barrel section, and after the medicinal pieces slide down to the upper folding plate of the inner folding plate that is separated from the right side of the drop channel, they fall in a parabolic manner to the lower folding plate of the outer folding plate of the right side of the drop channel of the bottom side-sliding anti-straight-fall string barrel section; the medicinal pieces slide down along the lower folding plate of the outer folding plate of the right side of the drop channel of the bottom side-sliding anti-straight-fall string barrel section, and after the medicinal pieces slide down to the lower folding plate of the outer folding plate that is separated from the right side of the drop channel, they fall in a parabolic manner to the loading tray at the bottom. So far, the sliding process of the medicinal pieces delivered by the middle upper conveyor belt is completed.

[0080] The sliding process of the bottom conveyor belt delivering the medicinal material slices: After the bottom conveyor belt delivers the medicinal material slices into the lower feeding port of the bottom side-sliding anti-straight-fall stringing tube section, the medicinal material slices fall directly into the loading tray at the bottom in a parabolic manner. This completes the sliding process of the bottom conveyor belt delivering the medicinal material slices.

[0081] ⑵, Right side cleaning:

[0082] After the conveyor belt of the medicine cabinet stops conveying, it waits for a few seconds until the medicinal materials are dropped into the container. Then the upper computer system sends a cleaning command to the control circuit board. The control circuit board controls the right electric control pipe switch valve on the right dust suction pipe to open. After the right electric control pipe switch valve is opened, negative pressure suction is formed in the right dust suction pipe and all the dust suction boxes on the right side.

[0083] At the same time, the control circuit board controls the reduction motor to start forward rotation, and the reduction motor shaft drives the lead screw to rotate forward through the coupling. The forward rotation of the lead screw in the lead screw nut generates a thrust that moves the lead screw nut to the right, pushing all the side-sliding anti-straight-fall string barrel sections to move to the right, until the limit block on the right side of the side-sliding anti-straight-fall string barrel section touches the right limit switch. After the control circuit board receives the information sent by the right limit switch, it immediately controls the reduction motor to stop rotating, and all side-sliding anti-straight-fall string barrel sections stop moving, but the dust collection does not stop. At this time, the right side of the middle partition of all side-sliding anti-straight-fall string barrel sections has moved close to the front of the right dust collection box. After the dust collection work is delayed for 2 seconds, the control circuit board controls the right side of the electric control pipeline switch valve to close the valve. At this point, one cleaning work is completed and waiting for the next cleaning work.

[0084] ⑶. Blanking and cleaning on the left side: When the blanking and cleaning on the right side is completed, the blanking channel on the left side is formed. The blanking and cleaning methods on the left side are exactly the same as those on the right side, so they will not be repeated here.
