Description

Technical Field

[0001] The invention relates to a side dumping type counterweight scale system and method. Background Art

[0002] At present, there are many practical demands in the packaging industry that require materials to be paired and mixed before packaging and then packaged after reaching the target weight. With the development of high technology today, this demand can be solved by automated equipment. There are many material weighing scales on the market, which generally have fast speed, high accuracy, and reduce labor.

[0003] The most commonly used counterweight scale for bulk materials is the belt counterweight scale. It performs high-speed calculation and processing according to the weight target. The control system will select six belt conveyor weighing units on the left and right sides of the belt counterweight scale that meet the quantitative target, and a long conveyor belt is set in the middle. When the belt counterweight scale is counterweighted, the quantitative weight target of the pre-packaged material is set first, and then the material is manually put into the empty weighing unit of the counterweight scale. After the material is put in, each tray will be automatically weighed and the weight will be recorded. Then, the automatic counterweight control system will calculate and confirm according to the optimal value of the preset weight target and command the successfully matched weighing unit to convey the material to the middle conveyor belt, which will be quickly transported to the packaging station by the conveyor line. In this way, the entire automatic counterweight combination process is completed. Because of the slippage of the belt, the speed matching will be inaccurate;

[0004] In the belt counterweight scale structure, the weighing units are arranged on both sides of the counterweight scale. Workers and materials to be weighed need to be arranged on both sides at the same time, which requires a large site and requires manual placement of materials around the counterweight scale many times in advance, increasing working time and work intensity. During the matching process of the belt counterweight scale, materials on the weighing units that are not successfully matched will occupy the work station until they are successfully matched and will be discharged from the weighing units, resulting in a waste of time on the weighing units and low work efficiency.

[0005] The existing tipping combination weigher has a V-shaped tipping bucket and a plurality of anti-sticking grooves on the bucket wall. When pouring materials into the lower combination bucket, the tipping bucket needs to rotate in the opposite direction to return to its original position after rotating to pour materials, which wastes time, and there are problems such as unclean dumping and long waiting time at the work station.

[0006] The existing weighing process can only dump in a single way, which is inefficient and cannot achieve two-way circulation and continuous falling dumping. Summary of the invention

[0007] The technical problem to be solved by the present invention is generally to provide a side-dumping weight scale system and method, which can be used to combine multiple block materials into a material scale with a set target weight, replacing manual weighing and then combining weight calculation.

[0008] To solve the above problems, the technical solution adopted by the present invention is:

[0009] In order to achieve continuous high-efficiency work and achieve the connection with the upper and lower processes, a side-dumping counterweight scale system includes a main frame; a conveyor belt for process connection is arranged on the main frame;

[0010] An output station is arranged on the conveyor belt;

[0011] A buffer component is arranged above the output station; a weighing component is arranged above the buffer component;

[0012] The weighing component quantitatively receives the material, and the weighing component can continuously rotate in one direction so that the quantitative material falls onto the buffer component for temporary storage;

[0013] The buffer component outputs the temporarily stored falling materials to a set position on the conveyor belt.

[0014] As a further improvement of the above technical solution:

[0015] In order to achieve compartmentalized storage, partition frames are distributed on the conveyor belt to receive the falling quantitative materials at the output station.

[0016] A pulley is arranged below the main frame;

[0017] A control panel is arranged above the main frame;

[0018] An indicator light is provided on the front panel of the main frame.

[0019] In order to achieve continuous action, several weighing components are arranged on the main frame;

[0020] The weighing assembly includes an upper weighing bucket which is rotatably arranged;

[0021] The upper weighing bucket rotates through the blanking station and the falling station.

[0022] As a further improvement of the above technical solution:

[0023] In order to realize the falling of materials, the upper weighing bucket is used to receive the materials at the material dropping station;

[0024] In order to realize material output, at the falling station, the upper weighing bucket dumps the material received at the dropping station;

[0025] In order to achieve continuous work, the drop station includes a drop station A and / or a drop station B;

[0026] When the material received by the blanking station reaches the set weight, the upper weighing bucket rotates, causing the material to fall from the blanking station to the falling station and separate from the upper weighing bucket.

[0027] In order to achieve better material loading, the upper weighing bucket has a middle recess for loading materials;

[0028] In order to improve efficiency, the upper weighing bucket is a Y-shaped structure;

[0029] The middle concave portion corresponds to the falling station and the blanking station.

[0030] The drop station and the blanking station are located in the Y-shaped concave part.

[0031] In order to reduce friction, the upper weighing bucket includes a number of baffle pieces;

[0032] Spacers are provided between adjacent partition members.

[0033] The partition pieces are connected in series through connecting rods;

[0034] In order to form a gap, a gap part is arranged on the connecting rod; the gap part is located at the gap gap;

[0035] The spacing part is a spacing sleeve or a spacing step.

[0036] In order to achieve continuous rotation, the upper weighing bucket is connected to the side dumping drive assembly;

[0037] In order to achieve weighing, the side dumping drive assembly includes a weighing mounting seat arranged on the main frame; a weighing sensor is arranged between the main frame and the weighing mounting seat;

[0038] A driving motor is arranged on the main frame, and the driving motor is connected to a connecting shaft through a coupling transmission;

[0039] The connecting shaft member is connected to the partition member;

[0040] Outer baffle members are provided at both ends of the partition member;

[0041] The outer baffle member is connected to the connecting shaft member.

[0042] In order to temporarily store quantitative materials, a buffer component is provided below the weighing component;

[0043] The cache assembly includes a lower cache bucket that is opened and closed;

[0044] The lower buffer bucket is located below the upper weighing bucket.

[0045] In order to realize the flipping of the lower buffer bucket, the lower buffer bucket is connected with an opening and closing drive assembly;

[0046] The opening and closing driving assembly includes a fixed cylinder mounting seat and a swing shaft fixing seat; a cylinder assembly is arranged on the cylinder mounting seat;

[0047] A swing connecting shaft is rotatably arranged on the swing shaft fixing seat; the swing connecting shaft is connected to the lower buffer bucket;

[0048] A swing shaft clamping block is hinged between the swing connecting shaft and the cylinder assembly.

[0049] In order to reduce friction and achieve better material falling, the lower buffer bucket is M-shaped, with the opening facing the end.

[0050] In order to realize the temporary storage of quantitative materials in compartments, vertical partitions A and B are arranged on both sides above the lower buffer hopper;

[0051] The upper weighing bucket is arranged below the vertical partition A; the vertical partition B is arranged between adjacent upper weighing buckets;

[0052] In order to achieve efficient material falling, vertical partitions B are arranged on both sides of a vertical partition A to form a buffer A cavity and a buffer B cavity;

[0053] The lower buffer buckets correspond to the lower parts of the buffer cavity A and the buffer cavity B respectively;

[0054] When one middle concave portion is located at the blanking station, the other two middle concave portions are located at the dropping station A and the dropping station B respectively;

[0055] The drop station A is located above the buffer A cavity;

[0056] The drop station B is located above the buffer B cavity;

[0057] In order to facilitate the rapid falling of materials and reduce friction resistance, the Y-shaped fingers have a circumferential slope on the cross section perpendicular to the axis of rotation, which becomes thinner as it approaches the end;

[0058] In the cross section along the center line of the rotating shaft, the Y-shaped finger has a shaft lateral inclined surface, which becomes thinner as it approaches the end, and the shaft lateral inclined surface is located on the side of the shaft lateral neutral position.

[0059] In order to realize the efficient circulation of falling materials, a side-dumping type counterweight method is provided, comprising the above-mentioned side-dumping type counterweight scale system; performing the following steps;

[0060] Step 1: First, send the material to the drop station; then, the weighing sensor monitors the weight of the material falling. When the weight reaches the set threshold, the upper weighing bucket turns 120 degrees to the drop station, and at the same time, the empty middle concave part turns unidirectionally to the drop station; when the material is temporarily stored in the drop station B, the material falls to the drop station A; when the material is temporarily stored in the drop station A, the material falls to the drop station B;

[0061] Step 2: First, temporarily store the materials at the drop station A and wait for the conveyor belt to move forward so that the partition frame reaches the output station; then, the lower buffer bucket swings downward so that the materials fall into the partition frame in a concentrated manner;

[0062] Step 3: The conveyor belt outputs and moves forward.

[0063] As a further improvement of the above technical solution:

[0064] In step 1, the driving motor drives the upper weighing bucket to rotate through the coupling and the connecting shaft;

[0065] In step 2, the cylinder assembly drives the lower buffer bucket through the swing shaft clamping block and the swing connecting shaft.

[0066] The invention has reasonable design, low cost, durability, safety and reliability, simple operation, time and labor saving, money saving, compact structure and convenient use.

[0067] Compared with the belt counterweight scale, the present invention is a completely new design concept. It does not require deviation correction and does not worry about slipping. Compared with the flip-type combination scale, the structure of this side-dumping counterweight scale is also completely different. The style of the weighing bucket is Y-shaped, while the flipping bucket of the flipping combination scale is V-shaped; the operation mode of the weighing bucket is single motion, while the operation mode of the flipping combination scale flipping bucket is forward and reverse reciprocating motion; the weighing bucket is a multi-layer stacking style, while the bucket wall of the flipping bucket is provided with a number of grooves; the lower part of this side-dumping counterweight scale is equipped with a conveyor belt, which can place each group of successfully paired materials between the two partitions of the same section to ensure that the weight of the materials placed between the two partitions of each section is the same. Workers stand on the side of the conveyor belt and take materials from the side between the two partitions. The bottom conveyor belt of the flipping combination scale has no partitions, and the materials are just placed on the conveyor belt. Each group of materials is placed scattered with large spacing. Workers need to wait for all the materials to be discharged before they can be packaged, which wastes working time.

[0068] The beneficial effects of the present invention are as follows: the side-dumping counterweight scale adopts an upper weighing bucket fixed on the upper part of the weighing sensor to weigh the material. After the material is weighed, the weighing bucket tilts sideways 120° to drop the material into the buffer bucket. Since the weighing bucket is a Y-shaped three-side hopper design, each time the weighing bucket tilts sideways 120°, one side of the hopper will be emptied and a new hopper will be exposed at the same time. This dumping method can reduce the shaking of the weighing bucket, which is beneficial to the stability of the weighing sensor, thereby improving the weighing accuracy of the weighing sensor, and saving the weighing response time of the weighing sensor, thereby improving the weighing efficiency. Through the design of the above structure, each weighing bucket corresponds to two left and right buffer buckets, providing two materials that can participate in counterweighting, greatly improving the counterweighting probability, and shortening the counterweighting time.

[0069] Compared with the belt-type counterweight scale, each weighing unit can only provide one material weight for counterweighting, and the unsuccessful matching materials occupy the weighing unit for a long time, which limits the counterweighting probability. The side-dumping counterweight scale avoids the shortcomings of the belt-type counterweight scale and significantly improves work efficiency.

[0070] Compared with the belt counterweight scale, the side-dumping counterweight scale is a one-sided loading system. Workers can load materials into the weighing bucket by standing on one side of the equipment, which reduces the labor intensity of workers and does not require a large space, which is conducive to the neat placement of materials in the workshop.

[0086] A buffer assembly 3 is disposed above the output station 36; a weighing assembly 2 is disposed above the buffer assembly 3;

[0087] The weighing component 2 quantitatively receives the material, and the weighing component 2 can continuously rotate in one direction so that the quantitative material falls onto the buffer component 3 for temporary storage;

[0088] The buffer component 3 outputs the temporarily stored falling materials to a set position on the conveyor belt 32 .

[0089] The weighing assembly 2 includes an upper weighing bucket 6 which is rotatably arranged to realize unidirectional rotation and falling;

[0090] The upper weighing bucket 6 rotates through the material dropping station 22 and the falling station, thereby achieving quantitative falling of materials.

[0091] At the material dropping station 22, the upper weighing bucket 6 is used to receive the material until the weight meets the set requirements;

[0092] At the falling station, the upper weighing bucket 6 dumps the material received at the material dropping station 22;

[0093] The dropping station includes dropping station A23 and / or dropping station B24; preferably, it is divided into three equal parts to achieve continuous output.

[0094] When the material received by the blanking station 22 reaches a set weight, the upper weighing bucket 6 rotates, so that the material falls from the blanking station 22 to the falling station and is separated from the upper weighing bucket 6 .

[0095] The upper weighing bucket 6 has a middle recess 28 for carrying materials, thereby realizing temporary storage, and its size and depth can be adjusted according to the material conditions;

[0096] The upper weighing bucket 6 is a Y-shaped structure, and can also be other similar structures to achieve multiple continuous actions.

[0097] The drop station and the material drop station 22 are located in the Y-shaped concave portion, thereby realizing temporary storage of materials.

[0098] The upper weighing bucket 6 includes a plurality of partition members 9 to realize axial side blocking of the material;

[0099] Spacers are provided between adjacent partition members 9 to reduce friction.

[0100] The partition members 9 are connected in series as a whole through the connecting rods 7 and connected by bolts;

[0101] The connecting rod 7 is eccentric to the rotation axis of the partition member 9, which can improve the strength and avoid the influence of the material in the root concave part;

[0102] A spacer 8 is provided on the connecting rod 7; the spacer 8 is located at the spaced gap;

[0103] The connecting rod 7 is eccentric to the rotation axis of the partition member 9, thereby increasing the strength, avoiding clamping of materials squeezed at the root, and facilitating cleaning.

[0104] The spacer 8 is a spacer sleeve or a spacer step or other equivalent structures.

[0105] The upper weighing bucket 6 is transmission-connected to the side dumping drive assembly 4; it can realize other rotating parts, such as gears, motors or other structures.

[0106] The side dumping drive assembly 4 includes a weighing mounting seat 13 disposed on the main frame 1; a weighing sensor 10 is disposed between the main frame 1 and the weighing mounting seat 13 to achieve weight monitoring;

[0107] As a specific description, a driving motor 11 is arranged on the main frame 1, and the driving motor 11 is connected to a connecting shaft 14 through a coupling 12;

[0108] The connecting shaft member 14 is connected to the partition member 9 to achieve the connection.

[0109] Outer baffles 15 are provided at both ends of the partition member 9, thereby realizing side blocking of materials.

[0110] Preferably, the outer baffle member 15 is connected to the connecting shaft member 14, and may also be connected in an equivalent manner.

[0111] A buffer component 3 is provided below the weighing component 2 to achieve temporary storage of materials and centralized falling.

[0112] As a specific mechanism, the cache assembly 3 includes a lower cache bucket 21 that is openable and closable;

[0113] The lower buffer bucket 21 is located below the upper weighing bucket 6 .

[0114] The lower buffer bucket 21 is connected to an opening and closing drive assembly 5, which can be driven by a conventional swing mechanism, such as a connecting rod or a motor;

[0115] The opening and closing driving assembly 5 includes a fixed cylinder mounting seat 16 and a swing shaft fixing seat 18; a cylinder assembly 17 is arranged on the cylinder mounting seat 16;

[0116] A swing connecting shaft 20 is rotatably mounted on the swing shaft fixing seat 18; the swing connecting shaft 20 is connected to the lower buffer bucket 21;

[0117] A swing shaft clamping block 19 is hinged between the swing connecting shaft 20 and the cylinder assembly 17 .

[0118] The lower buffer bucket 21 is M-shaped, and the opening of the M-shape faces the end, so that the material can fall quickly under the action of the swinging centrifugal force, and at the same time, it is convenient to clean.

[0119] As a working principle, the main frame 1 is the main body, and the material falls into the middle recess 28 located at the blanking station 22. The weight is monitored by the weighing sensor 10. When the weight reaches the set weight, the driving motor 11 drives the coupling 12, the weighing mounting seat 13, and the connecting shaft 14 to rotate the outer baffle member 15 and the partition member 9, so that the material reaches the dropping station A23 or the dropping station B24 from the blanking station 22, and the material falls into the lower buffer bucket 21.

[0120] The cylinder assembly 17 drives the lower buffer bucket 21 to swing downward centrifugally through the swing shaft fixing seat 18, the swing shaft clamping block 19, and the swing connecting shaft 20, so that the materials fall and leave.

[0121] Preferably, the upper weighing bucket 6 has a Y-shaped finger 37, thereby achieving continuous loading and unloading and improving efficiency.

[0122] The middle recess 28 corresponds to the falling station and the material dropping station 22, so as to achieve smooth loading and dropping of the material.

[0123] The upper weighing bucket 6 includes a plurality of partition members 9, which are convenient for cleaning and flushing, ventilation and drying, and for adjusting the length in the axial direction to meet the requirements of different load capacities.

[0124] Axial side gaps 30 are provided between adjacent partition members 9 to form gaps to reduce friction. In order to store materials temporarily, vertical partitions A38 and B39 are provided on both sides above the lower buffer bucket 21;

[0125] The upper weighing bucket 6 is arranged below the vertical partition A38, so that the material can fall accurately into the corresponding buffer cavity; the vertical partition B39 is arranged between adjacent upper weighing buckets 6 to separate the cavities;

[0126] As a specific illustration, vertical partitions B39 are provided on both sides of a vertical partition A38 to form a buffer A cavity 34 and a buffer B cavity 35;

[0127] The lower buffer buckets 21 correspond to the lower parts of the buffer chamber A 34 and the buffer chamber B 35, respectively, so as to realize the opening and closing of the corresponding buffer chambers;

[0128] When one middle recess 28 is located at the blanking station 22, the other two middle recesses 28 are located at the dropping station A23 and the dropping station B24, respectively, and one finger of the Y-shaped finger is vertically located above the vertical partition A38; thus, continuous operation is achieved;

[0129] The drop station A23 is located above the buffer A cavity 34;

[0130] The drop station B24 is located above the buffer B cavity 35;

[0131] In the cross section perpendicular to the axis of rotation, the Y-shaped finger 37 has a circumferential slope 29, which becomes thinner as it approaches the end; in the cross section along the axis of rotation, the Y-shaped finger 37 has a shaft lateral slope 31, which becomes thinner as it approaches the end, and the shaft lateral slope 31 is located on the side of the shaft lateral gap 30. It achieves low resistance and rapid falling, and at the same time, avoids the material from being stuck in the gap due to squeezing and unable to be separated.

[0132] As Example 2, Figure 1-8 The side-dumping type counterweight method of this embodiment includes the above-mentioned side-dumping type counterweight scale system; performing the following steps;

[0133] Step 1, first, send the material to the drop station 22; then, the weighing sensor 10 monitors the falling weight of the material. When the weight reaches the set threshold, the upper weighing bucket 6 turns 120 degrees to the drop station, and at the same time, the empty middle concave portion 28 turns unidirectionally to the drop station 22; when the drop station B24 temporarily stores the material, the material falls to the drop station A23; when the drop station A23 temporarily stores the material, the material falls to the drop station B24;

[0134] Step 2: First, temporarily store the materials at the drop station A23, and wait for the conveyor belt 32 to move forward so that the partition frame 33 reaches the output station 36; then, the lower buffer bucket 21 swings downward so that the materials fall into the partition frame 33 in a concentrated manner;

[0135] Step 3: The conveyor belt 32 outputs and moves forward.

[0136] In step 1, the driving motor 11 drives the upper weighing bucket 6 to rotate through the coupling 12 and the connecting shaft 14;

[0137] In step 2, the cylinder assembly 17 drives the lower buffer bucket 21 through the swing shaft clamping block 19 and the swing connecting shaft 20.

[0138] Example 3, as a specific application, Figure 1-5The upper weighing bucket 6 is a Y-shaped bucket with 120° openings on three sides, and the weighing bucket is designed with multi-layer partitions and hollow anti-sticking materials. The upper weighing bucket is provided with a side dumping drive component, which drives the weighing bucket to turn 120° to both sides to dump materials. The upper weighing bucket is located above the lower buffer bucket, and each upper weighing bucket has a corresponding lower buffer bucket on both sides. The lower buffer bucket is provided with an opening and closing drive component, which drives the buffer bucket to open downward more than 60° for easy dumping. Figure 4 .

[0139] In the side dumping drive assembly, the weighing mounting seat has an embedded bearing, one end of the connecting shaft is connected to the coupling through the weighing mounting seat, the coupling is connected to the drive motor, the other end of the connecting shaft is connected to the weighing bucket, and the weighing mounting seat is fixed to the upper end of the weighing sensor.

[0140] In the opening and closing drive assembly, there are two cylinder mounting seat mounting plates at the connecting end of the swing connecting shaft and the lower buffer bucket, and countersunk holes are arranged on the mounting plates. The two sides of the buffer bucket are fixedly connected by threads with matching bolts passing through the countersunk holes of the mounting plates.

[0141] The buffer bucket can be a flat plate with a plurality of long holes formed on the flat plate.

[0142] The main frame is preferably C-shaped when viewed from the side. A pulley is installed at the bottom of the main frame, and a telescopic foot is installed on the pulley. The upper part of the main frame is equipped with a drop station A and a drop station B. The drop station A is above the weighing bucket, and the drop station B is located on the left side of the upper part of the main frame. Figure 1 .

[0143] The weighing hopper is designed with three Y-shaped hoppers, and each hopper is opened at 120°. Each time the weighing hopper tilts 120°, one hopper will be emptied and a new hopper will be exposed. This dumping method can reduce the shaking of the weighing hopper, which is beneficial to the stability of the weighing sensor, thereby improving the weighing accuracy of the weighing sensor and saving the weighing response time of the weighing sensor.

[0144] There are two buffer buckets on the left and right under each weighing bucket, providing two materials that can be used for balancing, which greatly improves the probability of balancing and shortens the balancing time.

[0145] The side-dumping counterweight scale is a one-side loading system. Workers can load materials into the weighing bucket while standing on one side of the equipment, which reduces the labor intensity of workers.

[0146] The lower part of this side-dumping counterweight scale is equipped with a partition-type conveyor belt, which can place each group of successfully matched materials between the two partitions of the same section to ensure that the weight of the materials placed between the two partitions of each section is the same. Workers stand on the side of the conveyor belt and take the materials from the side between the two partitions, which increases the convenience of taking materials and improves work efficiency.

[0147] Compared with the side-dumping counterweight scale, the weighing hopper of the present invention is a Y-shaped three-side hopper design, and each side hopper is 120° open. Each time the weighing hopper tilts 120°, one side hopper will be emptied and a new hopper will be exposed at the same time, without the need to return to the origin in the opposite direction. This dumping method can reduce the shaking of the weighing hopper, which is beneficial to the stability of the weighing sensor, thereby improving the weighing accuracy of the weighing sensor and saving the weighing response time of the weighing sensor; the driving structure of the flip-type combination scale is relatively complex and requires transmission of parts such as gears. The side-dumping counterweight scale has a simple structure and is directly connected to the motor, which reduces costs and saves space. Figure 3 .
