When the receiving cups 22 are located below the discharging guide plate 14 (as shown in fig. 1), the receiving cups 22 can receive the materials from the discharging guide plate 14, and when the receiving cups 22 move to the upper side of each receiving cup 23, the second moving assembly 24 is used for enabling the materials in the receiving cups 23 to fall into the receiving cups 23. In this way, material may be collected in different receiving cups 23, depending on the weight of the material.

The automatic weighing and distributing device 300 provided by the embodiment of the application comprises a weighing unit 100 and a distributing unit 200, wherein the weighing unit 100 comprises a feeding guide plate 12, an electronic scale 13, a discharging guide plate 14 and a first moving assembly 15 which are connected in sequence, after a material to be weighed reaches the electronic scale 13 from the feeding guide plate 12 and is weighed, the first moving assembly 15 moves the weighed material to the discharging guide plate 14 from the scale surface of the electronic scale 13, the distributing unit 200 comprises a receiving cup 22, a second moving assembly 24 and a plurality of receiving cups 23, the receiving cup 22 receives the weighed material from the lower part of the discharging guide plate 14, the second moving assembly 24 drives the receiving cup 22 to move to the upper part of each receiving cup 23 from the lower part of the discharging guide plate 14 and enables the material in each receiving cup 23 to fall into the receiving cup 23, and the whole volume of the automatic weighing and distributing device 300 can be small, the influence of the feeding and discharging processes on the electronic scale 13 is small, the weighing precision of the electronic scale 13 can be ensured, and the automatic weighing and sorting device is suitable for automatic weighing and sorting of small materials including but not limited to precious metals.

Of course, the automatic weighing and distributing device 300 further comprises a controller (not shown) which is in communication connection with both the weighing unit 100 and the distributing unit 200. Specifically, the controller is in communication with the electronic scale 13, the first moving assembly 15 and the second moving assembly 24. The controller receives weight information fed back by the electronic scales 13 of the weighing unit 100, controls the first moving assembly 15 to move the materials which are weighed out of the electronic scales 13, and controls the second moving assembly 24 of the material distributing unit 200 to act according to the weight information, so that the materials are collected in the corresponding material receiving cups 23.

The weighing unit 100 can be applied to a production line, the upper end of the feeding guide plate 12 can be matched with a previous process on the production line, and materials produced and obtained in the previous work automatically reach the feeding guide plate 12. Of course, the material to be weighed can also be introduced from the upper end of the feed chute 12 by manually placing the material. There is no particular limitation.

Referring to fig. 1, the weighing unit 100 includes a first fixing frame 11, and an electronic scale 13, a feeding guide plate 12, a discharging guide plate 14 and a first moving assembly 15 are all fixedly disposed on the first fixing frame 11, so that the electronic scale 13, the feeding guide plate 12, the discharging guide plate 14 and the first moving assembly 15 are relatively fixed in position.

Specifically, as shown in fig. 2 to 4 and 6, the first fixing frame 11 includes a first base 111 and a housing 112. The first base 111 is disposed under the electronic scales 13 and the first moving assembly 15 to support the electronic scales 13 and the first moving assembly 15 from below. The case 112 is connected to the periphery of the first base 111, is closed, covers and protects the electronic scale 13 and the first movable member 15, and prevents other foreign objects from falling onto the scale pan surface of the electronic scale 13 from above and affecting the weighing result, and is dustproof.

As shown in fig. 2 and 3, the housing 112 includes a plurality of side plates 1121, and the plurality of side plates 1121 are sequentially connected and enclosed to form a closed shape. In this embodiment, the number of the side plates 1121 may be five, and the five side plates 1121 surround to form an open rectangular parallelepiped, and one end of the open rectangular parallelepiped faces the electronic scale 13 and is connected to the periphery of the first base 111. Thus, the weighing cell 100 is formed in a regular rectangular parallelepiped shape as a whole. Of course, the number of the side plates 1121 may be other according to specific needs, and the weighing unit 100 as a whole may have other shapes, which are not particularly limited herein.

Optionally, at least one side panel 1121 is configured to be movable relative to other side panels 1121 or the first base 111, etc., for example, to be capable of translating, opening, closing, turning, etc., so that the housing 112 can be opened and expose the electronic scale 13 and the first moving assembly 15, etc., inside the housing 112, thereby facilitating operations such as observation or cleaning of the inside of the housing 112.

The discharging guide plate 14 and the feeding guide plate 12 both pass through the side plate 1121 of the housing 112 and are connected with the electronic scale 13. The purpose of this is, on the one hand, that the housing 112 directly supports the discharge guide plate 14 and the feed guide plate 12, and on the other hand, that the upper end of the discharge guide plate 14 is located outside the housing 112 to facilitate the placement of the material, and that the lower end of the discharge guide plate 14 is located outside the housing 112 to facilitate the connection with the receiving cup 22 of the material distribution unit 200.

As shown in fig. 3, the feed guide 12 has a feed chute 120 for sliding the material. As shown in fig. 2 to 4 and 6, the feeding guide 12 is inclined toward the electronic scale 13, and when the material to be weighed enters the feeding chute 120 of the feeding guide 12 from the upper end of the feeding guide 12, the material to be weighed slides under its own weight until reaching the scale pan surface of the electronic scale 13. Similarly, as shown in fig. 3, the discharging guide plate 14 has a discharging chute 140 for the material to slide. As shown in fig. 2 to 4 and 6, the discharge guide 14 is inclined away from the electronic scale 13. When the material which has finished weighing is moved by the first moving assembly 15 to the upper end of the discharge guide 14, the material slides under its own weight until it falls into the receiving cup 22.

As shown in FIGS. 4 and 6, in one embodiment, the feed shoe 12 includes a first shoe body 121 and first baffle plates 122 attached to opposite sides of the first shoe body 121, with the feed chute 120 being formed between the first baffle plates 122 and above the first shoe body 121. The material slides obliquely downward along the upper surface of the first guide body 121, and the first baffle 122 is used to restrict the material from sliding out in the horizontal direction. The first guide body 121 penetrates the housing 112.

The horizontal width of the feed chute 120 is large in size, i.e., the feed guide 12 is substantially similar to a funnel, and its lower end has a gathering effect on the material, which ensures that the material slides down and then falls within a smaller range on the scale surface of the electronic scale 13 (or, when the scale surface itself is smaller, the feed guide 12 causes the material to fall on the scale surface in a gathering manner).

The first guide body 121 may be an integrally formed member, or may be a member formed by connecting a plurality of plate-like structures. The first baffle 122 and at least a portion of the first guide body 121 may be integrally formed, or may be separately manufactured and connected, and is not particularly limited herein.

As shown in fig. 1, 2 and 4 to 6, the feeding guide 12 further includes a front guide cylinder 124 connected to the front end of the first guide body 121, the front guide cylinder 124 is hollow and has two open ends, and the front guide cylinder 124 is located outside the housing 112 and fixed to the housing 112 and the first guide body 121. Specifically, as shown in fig. 4 to 6, the first guide body 121 may be fixed on the side plate 1121 by a first mounting plate 1122 provided on an outer surface of the side plate 1121; as shown in fig. 5, the front end guide cylinder 124 is fixed to the side plate 1121 by a second mounting plate 1123 and is positioned obliquely above the first guide body 121. The material to be weighed enters from the upper end opening of the front guide drum 124 and can directly enter the feeding chute 120 after sliding out from the lower end opening. The purpose of this is to avoid the material accidentally dropping when entering the feeding chute 120, ensure that the material can enter the feeding chute 120, and facilitate the butt joint with the previous process when the weighing unit 100 is applied to the production line.

Referring to fig. 3, 4 and 6, the discharging guide plate 14 is fixed on the side plate 1121 through a third mounting plate 1124. It will be appreciated that discharge guide 14 is preferably positioned so as not to interfere with the weighing process of electronic scale 13, e.g., discharge guide 14 is suspended relative to the pan surface of electronic scale 13.

As shown in fig. 4 and 6, the discharge guide 14 includes a second guide body 141 and second baffles 142 disposed at opposite sides of the second guide body 141. The discharge chute 140 is formed between the two second baffles 142 on the upper surface of the second guide body 141. Similarly, the horizontal width of the discharging chute 140 is gradually decreased from top to bottom, so that the material can be accurately fed into the receiving cup 22 after being gathered.

As shown in fig. 5, the housing 112 is provided with a setting plate 1125 extending toward the bottom wall of the feed chute 120 (i.e., the upper surface of the first fence body 121). The distance between the lower end of the setting plate 1125 and the upper surface of the first guide plate body 121 is smaller, specifically, larger than 0 and smaller than the size of the first baffle 122 in the vertical direction. The purpose of setting up like this is, the material by the lower extreme opening roll-off of front end guide 124 behind the effect of blockking of dialling positive board 1125, can keep sliding with laminating mutually between the upper surface of first baffle body 121, so for the slip of material on first baffle body 121 is more stable, can not produce the phenomenon such as jump of material, and then has reduced the problem that the material jumps out feeding slide 120, guarantees that the material can reach the surface of electronic scale 13.

Since the first guide body 121 is inclined, in order to ensure that the material can more accurately reach the surface of the electronic scale 13, as shown in fig. 4 and 6, the feeding guide 12 further includes a terminal guide 125 connected to the lower end of the first guide body 121, the terminal guide 125 is also hollow and has two open ends, and is vertically disposed, the upper end opening is connected to the lower end of the first guide body 121, and the lower end opening faces the scale pan surface of the electronic scale 13 vertically. Thus, the materials sliding along the surface of the first guide plate body 121 can vertically drop on the scale pan surface of the electronic scale 13 under the guidance of the end guide cylinder 125, the long-distance movement in the horizontal direction cannot occur, the scale pan surface range of the electronic scale 13 can be further prevented from sliding out, and the dropping range of the materials on the scale pan surface of the electronic scale 13 is ensured.

The first moving assembly 15 is used for moving the material on the scale pan surface of the electronic scale 13 to the discharging guide plate 14, and therefore, the first moving assembly 15 has a first position and a second position: in the first position, the first movable assembly 15 is vertically aligned with the scale pan surface of the electronic scale 13 and the lower end of the end guide 125, and in the second position, the material is separated from the first movable assembly 15 and automatically enters the discharge chute 140 of the discharge guide 14.

As shown in fig. 3, 4 and 6, in one embodiment, the first moving assembly 15 includes a first motor 151 and a material pushing plate 152, the first motor 151 is fixedly disposed on the first base 111 through a support 113 and is located inside the housing 112, the material pushing plate 152 is driven by the first motor 151 to rotate, and the end of the material pushing plate 152 forms a material pushing ring 1520, and the material pushing ring 1520 is in a ring shape with an open upper end and a lower end. In the first position, push ring 1520 is aligned with the lower end of end guide 125 and material falling from end guide 125 onto the scale surface of electronic scale 13 is confined within the space in the middle of push ring 1520. Therefore, on one hand, the position of the material on the scale surface of the electronic scale 13 can be further limited, so that the situation that the material cannot be weighed due to sliding out is avoided, on the other hand, as long as the material pushing plate 152 moves, the material pushing ring 1520 can drive the material inside the material pushing plate to move, when the material is driven to move to the surface of the material discharging guide plate 14, the material can automatically drop downwards and slide along the material discharging slide rail 140, and the material pushing plate 152 can reversely rotate and return to the first position to perform the next material pushing action.

Not limited to the above, in other alternative embodiments, the first movement assembly 15 may move the material by translation or other available means. For example, the first motor 151 drives the ejector plate 152 to reciprocate through a transmission (not shown) to switch the ejector plate 152 between the first position and the second position.

Wherein, optionally, as shown in fig. 6, the lower end of the tip guide 125 is formed with a flange extending radially outward. The purpose of such setting is that the size (inner diameter) of the inner space of the end guide 125 can be smaller, so that the range of the material falling on the scale surface of the electronic scale 13 can be smaller, and the flanging can ensure that the upper edge of the material pushing ring 1520 is completely shielded even if the material pushing ring 1520 is deviated, so that the material can be further ensured not to jump out of the material pushing ring 1520, and the continuity of the weighing process can be ensured.

In one embodiment, as shown in fig. 4 and 6, the first moving assembly 15 further includes at least one first sensor 153, the first sensor 153 is disposed on the first fixing frame 11, particularly on the supporting column 113, and both the first sensors 153 are in communication connection with the controller. The first sensor 153 is used for detecting the position of the material pushing plate 152, so as to position the material pushing plate 152 in the continuously reciprocating moving process, so as to ensure the accuracy of the position of the material pushing plate 152 after subsequent movement, and further ensure the accuracy of the positioning and pushing actions of the material pushing plate 152.

In an alternative embodiment, the number of the first sensors 153 is two. The two first sensors 153 are respectively disposed at two extreme positions of the moving path of the stripper plate 152 for detecting the stripper plate 152 when the stripper plate 152 reaches the first position and the second position, that is, when one of the first sensors 153 detects the stripper plate 152, it indicates that the stripper plate 152 is located at the first position at this time, and when the other first sensor 153 detects the stripper plate 152, it indicates that the stripper plate 152 is located at the second position at this time. The first sensor 153 feeds back the detection signal to the controller, so that the controller can obtain the position of the stripper plate 152, and accordingly can correspondingly control the position of the stripper plate 152 at the next moment, and the controller forms a closed loop for controlling the first motor 151, so that the accuracy of the action and the position of the stripper plate 152 and the first motor 151 can be ensured in the working process all the time.

Next, referring to fig. 1, the material distributing unit 200 further includes a second fixing frame 21, and the second moving assembly 24 and the material receiving cup 23 are disposed on the second fixing frame 21.

Specifically, as shown in fig. 1 and 7, the second fixing frame 21 includes a second base 211 and a bracket 212, the plurality of material receiving cups 23 are arranged on the second base 211 along the moving track of the material receiving cup 22, and the second moving assembly 24 drives the material receiving cup 22 to move. The second base 211 is substantially plate-shaped and has a large surface area for receiving a plurality of receiving cups 23.

As shown in fig. 1, the second fixing frame 21 and the first fixing frame 11 may be independent and do not affect each other, and the weighing unit 100 and the material distributing unit 200 may be used separately and adapted to other functional units; alternatively, in other alternative embodiments, the second fixing frame 21 and the first fixing frame 11 may be integrated or fixedly connected together, so that the weighing unit 100 and the material distributing unit 200 are fixedly connected together.

In one embodiment, as shown in fig. 7 and 8, the second moving assembly 24 includes a second motor 241 fixedly disposed on the second base 211, and a distribution arm 242 driven by the second motor 241 to rotate, one end of the distribution arm 242 is connected to the second motor 241 and rotatably supported on the bracket 212, the bracket 212 of the distribution arm 242 provides support for the distribution arm 242, and the other end of the distribution arm 242 is connected to the receiving cup 22. Each of the receiving cups 23 is provided on a rotation path of the distributing arm 242. The rotation of the distributing arm 242 by different angles can make the receiving cup 22 reach above different receiving cups 23, so that the material in the receiving cup 22 can be distributed in different receiving cups 23.

Of course, without limitation, in other alternative embodiments, the distributing arm 242 may be driven by the second motor 241 to perform translation or other movement, and only needs to be able to correspond to the upper portion of each receiving cup 23.

In one embodiment, the second motor 241 is a stepper motor. Thus, the controller can drive the second motor 241 to rotate by a corresponding angle by outputting a corresponding control signal to the second motor 241, so that the material dividing arm 242 and the material receiving cup 23 reach the upper side of the corresponding material receiving cup 23.

In one embodiment, the distributing arm 242 has a third position in which the receiving cup 22 is located below the discharge guide 14 and can receive the material from the discharge guide 14, and a fourth position which is the extreme end of the movement path of the distributing arm 242, i.e., the position of the receiving cup 23 that is farthest from the discharge guide 14 on the movement path of the receiving cup 22.

As shown in fig. 8, in one embodiment, the second moving assembly 24 further includes at least one second sensor 243, the second sensor 243 being communicatively coupled to the controller. The second sensor 243 is used for detecting the position of the distributing arm 242, so as to position the distributing arm 242 in the continuously reciprocating moving process, so as to ensure the accuracy of the position of the distributing arm 242 after subsequent movement, and further ensure the accuracy of the position of the receiving cup 22.

In an alternative embodiment, the number of the second sensors 243 is two, which are respectively provided at two extreme positions of the moving path of the distribution arm 242, and the second sensors 243 are used to detect the distribution arm 242 at the third position and the fourth position. That is, when one of the second sensors 243 detects the distribution arm 242, it indicates that the distribution arm 242 and the receiving cup 22 are at the third position, and when the other second sensor 243 detects the distribution arm 242, it indicates that the distribution arm 242 and the receiving cup 22 are at the fourth position. In this way, the controller obtains the limit position of the distributing arm 242, so that the action of the second motor 241 at the next moment and the position of the distributing arm 242 at the next moment can be correspondingly controlled, and the controller forms a closed loop for controlling the second motor 241 to a certain extent, so that the accuracy of the action and the position of the distributing arm 242 and the second motor 241 can be ensured in the working process all the time.

Of course, in other embodiments, a second sensor 243 may be provided at a position corresponding to each receiving cup 23, and when the second sensor 243 detects the distribution arm 242, that is, when the distribution arm 242 reaches the corresponding position, the material can be controlled to fall from the receiving cup 22. In this case, the second motor 241 may be a non-stepping motor, but may also be a stepping motor.

As shown in fig. 7 to 9, in one embodiment, the second moving assembly 24 further includes a third motor 245 disposed on the distribution arm 242 and a third baffle 246 driven by the third motor 245 to move, and the third baffle 246 moves to open and close the opening of the bottom of the receiving cup 22. When the opening at the bottom of the receiving cup 22 is closed, the material can be received from the discharge guide 14, and when the opening at the bottom of the receiving cup 22 is opened, the material in the receiving cup 22 can fall.

Thus, the third baffle 246 has a fifth position and a sixth position, the fifth position being a position that closes the opening at the bottom of the receiving cup 22, and the sixth position being a position that opens the opening at the bottom of the receiving cup 22.

As shown in fig. 8 and 9, the second moving assembly 24 further includes at least one third sensor 244, and the third sensor 244 is in communication connection with the controller, and is used for detecting the position of the third baffle 246 and positioning the third baffle 246 during the continuous reciprocating movement process, so as to ensure the accuracy of the position of the third baffle 246 after the subsequent movement, and thus the accuracy of the material receiving and releasing actions of the material receiving cup 22.

In one embodiment, the second moving assembly 24 includes two third sensors 244, and the two third sensors 244 are respectively disposed on the distribution arm 242 and are both in communication with the controller. And, the two third sensors 244 are provided at two extreme positions of the moving path of the third barrier 246. Thus, when one of the third sensors 244 detects the third blocking plate 246, it indicates that the opening of the bottom of the receiving cup 22 is in the closed state, and when the other third sensor 244 detects the third blocking plate 246, it indicates that the opening of the bottom of the receiving cup 22 is in the open state. In this way, the controller obtains the position of the third baffle 246, and accordingly can control the action of the third motor 245 at the next moment and the position of the third baffle 246 at the next moment, thereby ensuring the accuracy of the position of the third baffle 246 at different moments and ensuring the accuracy of material distribution.

The third baffle 246 may translate, rotate, or otherwise close and open the opening at the bottom of the receiving cup 22. For example, as shown in fig. 9, in the present embodiment, the output shaft of the third motor 245 is connected to a connecting rod 247, one end of the connecting rod 247 away from the third motor 245 is movably disposed in a strip-shaped hole 2461 on the third baffle 246, and the extending direction of the strip-shaped hole 2461 is perpendicular to the translation direction of the third baffle 246 and both lie in the rotation plane of the connecting rod 247. When the output shaft of the third motor 245 drives the connecting rod 247 to rotate, the rotation of the end of the connecting rod 247 away from the third motor 245 is converted into the translation of the third baffle 246.

Of course, as shown in fig. 9, the receiving cup 22 is located on the upper surface of the distributing arm 242, the lower end opening of the receiving cup 22 penetrates through to the lower surface of the distributing arm 242, and the third baffle 246 is located on the lower surface of the distributing arm 242. The third baffle 246 is further provided with a plurality of guide holes 2462, the guide holes 2462 are elongated and extend along the translation direction of the third baffle 246, and structural members such as a stop pin 2420 penetrate through the guide holes 2462 and limit the third baffle 246 on the lower surface of the feed arm 242, so that the third baffle 246 is attached to the lower surface of the feed arm 242 and slides under the limit of the guide holes 2462.

In addition, as shown in fig. 1 and fig. 7 to 9, the material separating unit 200 further includes a plurality of protective covers 248, wherein one of the protective covers 248 is disposed on the second base 211 for protecting and covering the bracket 212 and the second motor 241, the second sensor 243, etc., and the other protective cover 248 is disposed on the material separating arm 242 for protecting the third motor 245, etc.

The automatic weighing and distributing device 300 of the application has the following working process:

the material to be weighed enters from the feeding guide plate 12 and slides downwards to the surface of a scale pan of an electronic scale 13; the electronic scale 13 is used for weighing the materials and feeding back the weighing result to the controller; the controller receives the weighing result and then controls the first motor 151 to rotate, the material pushing plate 152 moves from the first position to the second position, and the weighed material is pushed onto the material discharging guide plate 14; the distributing arm 242 is in the third position, and the material slides from the discharging guide plate 14 and falls into the receiving cup 22; the controller controls the distributing arm 242 to rotate by a corresponding angle according to the weighing result, and the distributing arm 242 and the receiving cup 22 reach the upper part of the corresponding receiving cup 23; the controller controls the third motor 245 to rotate, so that the opening at the bottom of the receiving cup 22 is opened after the third baffle 246 moves, the material falls into the receiving cup 23, and the controller receives the information fed back by the third sensor 244; the controller controls the third motor 245 to rotate reversely, and the third baffle 246 moves to close the opening at the bottom of the receiving cup 22; the controller controls the second motor 241 to rotate and return the dispensing arm 242 to the third position.
