Description

Technical Field

[0001] This utility model relates to the field of packaging production technology, and in particular to a linear combination scale. Background Technology

[0002] A typical combination scale uses a dispersing feeder to radially vibrate and disperse the supplied material, and then multiple linear feeders to linearly vibrate and transport the dispersed material outwards, supplying it to the feed hoppers facing the ends of each linear feeder. Each feed hopper opens its gate to supply the material to the multiple metering hoppers located below, and the combination scale then selects the combination of metering hoppers. In this type of combination scale, the multiple feed hoppers are arranged in a ring. When the overall volume of the combination scale is large, it only has one or two discharge channels. However, in some space-constrained production workshops, it is often necessary to densely distribute multiple packaging units of packaging machines within a small space. For example, some packaging machines have multiple packaging units arranged in a straight line, each with a packaging inlet. Traditional combination scales cannot meet this requirement. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a linear combination scale with a very compact structure that can accommodate multiple packaging units in a small space.

[0004] A linear combination scale according to an embodiment of the present invention includes: a body, wherein multiple combination scale units are sequentially arranged along a first horizontal line, each combination scale unit includes a feeding bin and two receiving bin assemblies disposed opposite to each other about the first horizontal line, each receiving bin assembly includes two storage bins spaced apart along the first horizontal line, each storage bin having a first weighing bin and a second weighing bin spaced apart below it along a second horizontal line, the second horizontal line being orthogonal to the first horizontal line, the feeding bin being used to receive the measured material output from the first weighing bin and the second weighing bin, and each storage bin having a switching mechanism, the switching mechanism being capable of selectively opening a first opening toward the first weighing bin or opening a second opening toward the second weighing bin.

[0005] The inline combination scale according to the embodiments of this utility model has at least the following beneficial effects:

[0006] The above-described inline combination scale has one feeding bin connected to two combination scale units. Each combination scale unit is equipped with two storage bins. Each storage bin can selectively input the measured material into the corresponding first or second weighing bin via a switching mechanism. That is, one feeding bin can receive the measured material released from four first weighing bins and four second weighing bins, thus forming a weighing mode with eight bins that can be freely combined. This allows the inline combination scale to be equipped with multiple feeding bins along the first horizontal line. The structure is very compact and can accommodate multiple packaging units in a small space, thereby improving workshop utilization and packaging production efficiency. The computer unit of the inline combination scale records the weight data of the items to be measured in each first and second weighing bin of the same combination scale unit. By freely combining them, a combination method close to the target weight is obtained. When some first and second weighing bins release the items to be measured, these released items are gathered in the unloading bin and output to the corresponding packaging unit. Then, the storage bin selects to open the first or second opening to replenish the items to be measured, depending on whether the first or second weighing bin is empty. Then, the process of freely combining is entered again. This design can reduce the number of storage bins, which helps to simplify the construction of the combination scale and save space.

[0007] In some embodiments of this utility model, the storage bin has a storage cavity that runs vertically through it, and the switching mechanism includes a first door plate and a second door plate movably disposed at the lower port of the storage cavity. The first door plate and the second door plate can be tilted to form a "V" shape to close the lower port of the storage cavity. When the lower port of the storage cavity is closed, the first door plate is tilted toward the interior of the first weighing bin, and the second door plate is tilted toward the interior of the second weighing bin.

[0008] In some embodiments of this utility model, the lower ends of the two side plates of the storage bin arranged at intervals along the first horizontal line are each provided with a V-shaped plate. The first door plate and the second door plate are rotatably connected to the storage bin. The first door plate is connected to a first elastic member that drives it to abut against one side edge of the two V-shaped plates. The second door plate is connected to a second elastic member that drives it to abut against the other side edge of the two V-shaped plates. A first linkage rod group is provided between the storage bin and the first door plate. A second linkage rod group is provided between the storage bin and the second door plate. The switching mechanism further includes a first driver for driving the first linkage rod group to move so that the first door plate opens the second opening and a second driver for driving the second linkage rod group to move so that the second door plate opens the first opening.

[0009] In some embodiments of this utility model, the first driver includes a first motor and a first crank disposed on the output shaft of the first motor. The first linkage group includes a first rotating arm rotatably disposed on the storage bin. One end of the first rotating arm is rotatably connected to the first door panel via a first connecting rod. The other end of the first rotating arm is connected to a first driving rod opposite to the first crank. When the first crank rotates, it contacts the first driving rod to rotate the first rotating arm and drive the first door panel to rotate and open the first opening. The second driver includes a second motor and a second crank disposed on the output shaft of the second motor. The second linkage group includes a second rotating arm rotatably disposed on the machine body. One end of the second rotating arm is rotatably connected to the second door panel via a second connecting rod. The other end of the second rotating arm is connected to a second driving rod opposite to the second crank. When the first crank rotates, it contacts the second driving rod to rotate the second rotating arm and drive the second door panel to rotate and open the second opening.

[0010] In some embodiments of this utility model, there is a height space between the storage bin and the first weighing bin, and between the storage bin and the second weighing bin, and there is a gap between the first weighing bin and the second weighing bin. A guide sleeve is provided in the height space. The guide sleeve is provided with a first channel for guiding the measured material flowing out of the first opening to the first weighing bin and a second channel for guiding the measured material flowing out of the second opening to the second weighing bin.

[0011] In some embodiments of this utility model, the guide sleeve is provided with an inverted V-shaped guide plate inside. The two side walls of the guide plate extend toward the first weighing chamber and the second weighing chamber, respectively. The guide sleeve is connected to the machine body through an L-shaped bracket. The L-shaped bracket is provided with a first waist-shaped hole extending in the vertical direction and a second waist-shaped hole extending in the horizontal direction. A first bolt passes through the first waist-shaped hole and is connected to the machine body, and a second bolt passes through the second waist-shaped hole and is connected to the guide sleeve.

[0012] In some embodiments of this utility model, the machine body is provided with a feeding bin above the combined scale unit, and a discharge port corresponding to the storage bin is provided below the feeding bin. The feeding bin is provided with an inverted V-shaped diverting plate, and the two side walls of the diverting plate guide the measured material to be distributed to the discharge ports located on both sides of the first horizontal line. A conveying track is provided between the discharge port and the corresponding storage bin, and a vibrator is provided below the conveying track to drive the measured material to the storage bin.

[0013] In some embodiments of this utility model, the side wall of the flow divider is provided with partition strips arranged at intervals along the length direction of the flow divider, and a guide channel communicating with the discharge port is defined between two adjacent partition strips. The guide channel has a funnel-shaped opening that gradually narrows from top to bottom.

[0014] In some embodiments of this utility model, the machine body is movably provided with a flow-limiting plate that can change the size of the connection between the discharge port and the conveying track.

[0015] In some embodiments of this utility model, the flow limiting plate is provided with a long strip hole arranged in the vertical direction, and the threaded fastener is passed through the long strip hole and tightened on the machine body. The lower end of the flow limiting plate is provided with an arc-shaped plate extending toward the bottom surface of the conveying track, and there is a height distance between the arc-shaped plate and the bottom surface of the conveying track.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] See Figures 1 to 3 This utility model discloses a linear combination scale, comprising: a body 100, wherein multiple combination scale units 200 are sequentially arranged along a first horizontal line. Each combination scale unit 200 includes a feeding bin 210 and two receiving bin assemblies 220 disposed opposite to each other about the first horizontal line. Each receiving bin assembly 220 includes two storage bins 221 spaced apart along the first horizontal line. Below each storage bin 221, a first weighing bin 222 and a second weighing bin 223 are spaced apart along a second horizontal line. The second horizontal line is orthogonal to the first horizontal line. The feeding bin 210 is used to receive the measured material output from the first weighing bin 222 and the second weighing bin 223. Each storage bin 221 is provided with a switching mechanism 230, which can selectively open a first opening facing the first weighing bin 222 or a second opening facing the second weighing bin 223.

[0031] The above-described inline combination scale has one feeding bin 210 connected to two combination scale units 200. Each combination scale unit 200 is equipped with two storage bins 221. Each storage bin 221 can selectively input the measured material into the corresponding first weighing bin 222 or second weighing bin 223 through a switching mechanism 230. That is, one feeding bin 210 can receive the measured material released from four first weighing bins 222 and four second weighing bins 223, thereby forming a weighing mode with eight bins that can be freely combined. This allows the inline combination scale to be equipped with multiple feeding bins 210 along the first horizontal line. The structure is very compact and can accommodate multiple packaging units in a small space, thereby improving workshop utilization and packaging production efficiency. In this embodiment, the vertical projection of the body 100 is approximately rectangular. The first horizontal line is the length direction of the body 100, and the second horizontal line is the width direction of the body 100. It can be imagined that the above-mentioned inline combination scale can form multiple linearly arranged combination scale units 200 with a very small width. Specifically, the computer unit of the inline combination scale records the weight data of the measured items in each of the first weighing bins 222 and second weighing bins 223 of the same combination scale unit 200. Through free combination, a combination method close to the target weight is obtained. When some of the first weighing bins 222 and second weighing bins 223 release the measured items, these released measured items converge in the unloading bin 210 for output to the corresponding packaging unit. Then, the storage bin 221 selects to open the first or second opening to replenish the measured items based on whether the first weighing bin 222 or second weighing bin 223 is empty. Then, the process of free combination resumes. This design can reduce the number of storage bins 221, which helps to simplify the structure of the combination scale and save space.

[0032] It should be noted that each of the first weighing chambers 222 and the second weighing chambers 223 has a switch structure for opening or closing its inner cavity. This switch structure is conventional technology in the field and will not be described in detail here.

[0033] See Figure 3 and Figure 4 In some embodiments of this utility model, the storage bin 221 has a storage cavity that runs vertically through it, and the switching mechanism 230 includes a first door plate 231 and a second door plate 232 movably disposed at the lower port of the storage cavity. The first door plate 231 and the second door plate 232 can be tilted to form a "V" shape to close the lower port of the storage cavity. When the lower port of the storage cavity is closed, the first door plate 231 is tilted toward the interior of the first weighing bin 222, and the second door plate 232 is tilted toward the interior of the second weighing bin 223.

[0034] Each storage bin 221 has a first door panel 231 and a second door panel 232. By selectively opening the first door panel 231 or the second door panel 232, the material to be measured can be input into the first weighing bin 222 or the second weighing bin 223. Specifically, when the first weighing bin 222 needs to be replenished with the material to be measured, the switching mechanism 230 opens the second door panel 232 to expose the first opening, and the material to be measured can slide down along the inclined angle of the first door panel 231 to enter the first weighing bin 222; when the second weighing bin 223 needs to be replenished with the material to be measured, the switching mechanism 230 opens the first door panel 231 to expose the second opening, and the material to be measured can slide down along the inclined angle of the second door panel 232 to enter the second weighing bin 223, which facilitates the smooth input of the material to be measured into the first weighing bin 222 or the second weighing bin 223.

[0035] See Figure 4 and Figure 5 In some embodiments of this utility model, the lower ends of the two side plates of the storage bin 221, which are spaced apart along the first horizontal line, are each provided with a V-shaped plate. The first door plate 231 and the second door plate 232 are rotatably connected to the storage bin 221. The first door plate 231 is connected to a first elastic member 233 that drives it to abut against one side edge of the two V-shaped plates. The second door plate 232 is connected to a second elastic member 234 that drives it to abut against the other side edge of the two V-shaped plates. A first linkage rod group 300 is provided between the storage bin 221 and the first door plate 231. A second linkage rod group 400 is provided between the storage bin 221 and the second door plate 232. The switching mechanism 230 further includes a first driver 235 for driving the first linkage rod group 300 to move so that the first door plate 231 opens the second opening and a second driver 236 for driving the second linkage rod group 400 to move so that the second door plate 232 opens the first opening.

[0036] Understandably, under the action of the first elastic member 233 and the second elastic member 234, the first door plate 231 and the second door plate 232 keep the lower port of the storage chamber closed. The arrangement of the two V-shaped plates enables the metered material to be quickly released when the first door plate 231 or the second door plate 232 is opened, and the sealing effect between the first door plate 231, the second door plate 232 and the two V-shaped plates is good. When the object to be measured needs to be input into the first weighing chamber 222, the second driver 236 drives the second door plate 232 to overcome the action of the second elastic member 234 and open a part of the lower port of the storage chamber, thus exposing the first opening. The object to be measured can then flow into the first weighing chamber 222 along the inclined direction of the first door plate 231. When the object to be measured needs to be input into the second weighing chamber 223, the first driver 235 drives the first door plate 231 to overcome the action of the first elastic member 233 and open a part of the lower port of the storage chamber, thus exposing the second opening. The object to be measured can then flow into the second weighing chamber 223 along the inclined direction of the second door plate 232.

[0037] See Figure 4 and Figure 5 In some embodiments of this utility model, the first driver 235 includes a first motor 2351 and a first crank 2352 disposed on the output shaft of the first motor 2351. The first linkage group 300 includes a first rotating arm 310 rotatably disposed on the storage bin 221. One end of the first rotating arm 310 is rotatably connected to the first door panel 231 by a first connecting rod 320. The other end of the first rotating arm 310 is connected to a first driving rod 330 opposite to the first crank 2352. When the first crank 2352 rotates, it contacts the first driving rod 330 to make the first rotating arm 310 rotate, thereby driving the first door panel 231 to rotate open. The first opening is opened; the second driver 236 includes a second motor 2361 and a second crank 2362 disposed on the output shaft of the second motor 2361; the second linkage group 400 includes a second rotating arm 410 rotatably disposed on the body 100; one end of the second rotating arm 410 is rotatably connected to the second door panel 232 by a second connecting rod 420; the other end of the second rotating arm 410 is connected to a second driving rod 430 opposite to the second crank 2362; when the first crank 2352 rotates, it contacts the second driving rod 430 to make the second rotating arm 410 rotate, thereby driving the second door panel 232 to rotate and open the second opening.

[0038] It should be noted that when the computer unit of the inline combination scale detects that a first weighing bin 222 or a second weighing bin 223 is empty, it can control the corresponding first motor 2351 or second motor 2361 to rotate, thereby replenishing the weighed item in the first weighing bin 222 or the second weighing bin 223. Specifically, when the first motor 2351 rotates, the first crank 2352 actuates the first drive rod 330 to rotate the first rotating arm 310. The first rotating arm 310, through the first connecting rod 320, drives the first door plate 231 to rotate, thereby opening the second opening. When the second motor 2361 rotates, the second crank 2362 actuates the second drive rod 430 to rotate the second rotating arm 410. The second rotating arm 410, through the second connecting rods 420 and 422, drives the second door plate 232 to rotate, thereby opening the first opening. This structure is simple, reliable, and easy to manufacture and assemble. Of course, in other embodiments, the first driver 235 and the second driver 236 can also be replaced by cylinders. The cylinder body is rotatably connected to the body 100, and the cylinder extension rod is rotatably connected to the first door panel 231 or the second door panel 232. This method can also realize the opening and closing of the first door panel 231 and the second door panel 232.

[0039] See Figure 3 and Figure 4 In some embodiments of this utility model, there is a height space between the storage bin 221 and the first weighing bin 222, and between the storage bin 221 and the second weighing bin 223. There is a gap between the first weighing bin 222 and the second weighing bin 223. A guide sleeve 500 is provided in the height space. The guide sleeve 500 is provided with a first channel 510 for guiding the measured material flowing out of the first opening to the first weighing bin 222 and a second channel 520 for guiding the measured material flowing out of the second opening to the second weighing bin 223. It is understood that the height space between the storage bin 221 and the first weighing bin 222, and between the storage bin 221 and the second weighing bin 223, can prevent interference between the first door panel 231 and the second door panel 232 during rotation, and provide sufficient room for movement; the gap between the first weighing bin 222 and the second weighing bin 223 can prevent them from getting too close and causing the measured object to accidentally fall outside the preset first weighing bin 222 or second weighing bin 223. When the second door panel 232 opens the first opening, the measured object flowing out of the first opening enters the first weighing bin 222 along the first channel 510; when the first door panel 231 opens the second opening, the measured object flowing out of the second opening enters the second weighing bin 223 along the second channel 520, ensuring the accuracy of the measured object delivery.

[0040] See Figure 4In some embodiments of this utility model, the guide sleeve 500 has an inverted V-shaped guide plate 530 inside. The two side walls of the guide plate 530 extend toward the first weighing chamber 222 and the second weighing chamber 223, respectively. The guide sleeve 500 is connected to the machine body 100 through an L-shaped bracket 540. The L-shaped bracket 540 has a first waist-shaped hole 541 extending vertically and a second waist-shaped hole 542 extending horizontally. A first bolt passes through the first waist-shaped hole 541 and is connected to the machine body 100, and a second bolt passes through the second waist-shaped hole 542 and is connected to the guide sleeve 500. It can be understood that the measured material flowing out from the first opening falls onto one side wall of the guide plate 530 and enters the first channel 510, and the measured material flowing out from the second opening falls onto the other side wall of the guide plate 530 and enters the second channel. When the measured object falls incorrectly on the side wall of the guide plate 530, the user can loosen the first and second bolts and adjust the position of the guide sleeve 500 along the second horizontal line and in the height direction to solve the problem, which is helpful for production debugging.

[0041] See Figure 1 and Figure 6 In some embodiments of this utility model, the machine body 100 is provided with a feeding bin 600 above the combined weighing unit 200. Below the feeding bin 600 are discharge ports corresponding to the storage bins 221. The feeding bin 600 contains an inverted V-shaped diverting plate 620. The two side walls of the diverting plate 620 guide the measured material to be distributed to the discharge ports located on both sides of the first horizontal line. A conveying track 700 is provided between the discharge ports and the corresponding storage bins 221. Below the conveying track 700 is a vibrator that drives the measured material to move to the storage bin 221. It can be understood that when a large amount of measured material is poured into the feeding bin 600, it is quickly divided into two parts located on both sides of the first horizontal line under the action of the diverting plate 620, thus entering each discharge port with a relatively uniform flow rate. After passing through the discharge ports, it enters the conveying track 700 and is linearly fed to the storage bins 221 under the action of the vibrator.

[0042] See Figure 6 In some embodiments of this utility model, in order to guide the metered material to be evenly distributed to each discharge port in a more orderly manner, the side wall of the diversion plate 620 is provided with partition strips 630 arranged at intervals along the length direction of the diversion plate 620, and a guide channel 640 connected to the discharge port is defined between two adjacent partition strips 630. The guide channel 640 has a flared opening that gradually narrows from top to bottom.

[0043] See Figure 3In some embodiments of this utility model, the machine body 100 is movably provided with a flow-limiting plate 800 capable of changing the size of the connection between the discharge port and the conveying track 700. It can be understood that the size of the connection between the discharge port and the conveying track 700 can be adjusted by adjusting the position of the limiting plate, thereby adjusting the flow rate of the measured material.

[0044] See Figure 3 In some embodiments of this utility model, the flow-limiting plate 800 is provided with a vertically oriented elongated hole 810, and a threaded fastener 820 passes through the elongated hole 810 and is tightened onto the machine body 100. The lower end of the flow-limiting plate 800 is provided with an arc-shaped plate 830 extending towards the bottom surface of the conveying track 700, and there is a height distance between the arc-shaped plate 830 and the bottom surface of the conveying track 700. It can be understood that when the user loosens the threaded fastener 820, the flow-limiting plate 800 can be raised or lowered by a certain position, thereby adjusting the height distance between the arc-shaped plate 830 and the bottom surface of the conveying track 700. Finally, the threaded fastener 820 can be tightened, making adjustment very convenient.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
