Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a feeding mechanism 100 according to the present disclosure. In this embodiment, the feeding mechanism 100 may include an inlet channel 110, a dispensing assembly 140, and an inlet assembly 150. The feeding channel 110 is used for conveying the objects 20, and may include a feeding section 111 and a circulation section 112, and the objects may sequentially pass through the feeding section 111 and the circulation section 112 from the upstream of the feeding channel 110 and be conveyed to the downstream of the feeding channel 110; the material distributing assembly 140 is arranged on the feeding section 111 and is used for delivering the articles 20 conveyed from the upstream of the feeding channel 110 to the material receiving station 10; the feeding assembly 150 is disposed on the circulation section 112, and is used for receiving the articles 20 transferred from the material-separating assembly 140 from the material-receiving station 10 and conveying the articles to the downstream of the feeding channel 110.

Wherein, the upstream of the feeding channel 110 may be connected to a conveying assembly (not shown) which may continuously convey the objects 20 into the feeding channel 110; downstream of the infeed channel 110 may be connected to other equipment, such as a packaging machine.

The cross section of the object 20 conveyed by the feeding mechanism 100 in this embodiment is circular. For example, the article 20 may be a cylindrical article, such as a battery, beverage can, pipe, or the like; of course, in other embodiments, the object 20 may also be a spherical object 20, a conical object 20, etc., which is not further limited in this application.

When the feeding mechanism 100 in this embodiment conveys the articles 20, the material separating assembly 140 can separate the unordered articles 20 one by one and transfer the separated articles to the material receiving station 10, facing the articles 20 passing through the material receiving section 111; the feeding assembly 150 can sequentially pick up the articles 20 transferred from the material separating assembly 140 at the receiving station 10, and then convey the articles 20 downstream of the feeding channel 110 at the turning section 112.

As will be readily appreciated, the recirculation section 112 is essentially the path of movement of the articles 10 conveyed by the infeed assembly 150. Further, in order to prevent the objects 10 from deviating from the feeding assembly 150 when the feeding assembly 150 conveys the objects 10, a rail is disposed outside the moving track of the feeding assembly 150, which can limit the moving direction of the objects 20.

The receiving station 10 is essentially a station where the dispensing assembly 140 and the feeding assembly 150 interface the articles 20. Since the circulation section 112 is substantially a moving track of the feeding assembly 150 for conveying the articles 10, it is easy to understand that the receiving station 10 is located at the connection between the feeding section 111 and the circulation section 112.

Therefore, the feeding mechanism 100 in this embodiment sequentially sets the material separating assembly 140 and the material feeding assembly 150 on the material feeding channel 110 along the conveying direction of the articles 20, and the material separating assembly 140 and the material feeding assembly 150 transfer the articles 20 at the material receiving station 10, so that the unordered articles 20 can be sorted one by one and output one by one; on the one hand, clogging of the feed channel 110 is avoided and, on the other hand, subsequent treatment of the articles 20 by downstream equipment is facilitated. Further, with continued reference to fig. 1, in an embodiment, the material distribution assembly 140 may include a material distribution tray 141 and a material distribution driving member (not shown), which is connected to the material distribution tray 141 and drives the material distribution tray 141 to rotate circularly. The material distribution driving member may be a motor, the material distribution tray 141 may be connected to the motor shaft 143 of the material distribution driving member, and the material distribution tray 141 may rotate along with the motor shaft 143 of the material distribution driving member.

Optionally, the distribution tray 141 is provided with a plurality of first receiving grooves 142 uniformly distributed on the periphery thereof, and the shapes of the first receiving grooves 142 are matched with the cross-sectional shapes of the objects 20. When the objects 20 are received, the material distribution tray 141 can engage the objects 20 through the first material receiving groove 142, so as to separate the objects 20 passing through the material feeding section 111 one by one, and transfer the objects to the material receiving station 10, so that the material feeding assembly 150 receives and transfers the objects 20. Alternatively, the dispensing disc 141 in this embodiment may be a ratchet. A plurality of receiving members (not shown) are uniformly arranged on the periphery of the distributing tray 141, the configuration of the receiving members is similar to that of the first receiving groove 142, and the receiving members can receive the objects 20.

Further, the feeding assembly 150 may include a feeding tray 151 and a feeding driving member (not shown), which is connected to the feeding tray 151 and drives the feeding tray 151 to rotate circumferentially. The feeding tray 151 may be connected to the motor shaft 153 of the feeding driving member, and the feeding tray 151 may rotate along with the motor shaft 153 of the feeding driving member.

Optionally, the periphery of the feeding tray 151 is provided with a plurality of second receiving grooves 152 which are uniformly distributed, and the shape of the second receiving grooves 152 is matched with the cross-sectional shape of the object 20. When the material receiving station 10 receives the articles 20, the second material receiving groove 152 on the material receiving station 10 on the material feeding tray 151 and the first material receiving groove 142 on the material distributing tray 141 on the material receiving station 10 are arranged oppositely, so that the second material receiving groove 152 receives and clamps the articles 20 from the first material receiving groove 142, and then conveys the articles 20 to the downstream of the material feeding channel 110, thereby ensuring that the articles 20 flowing into the downstream equipment are tidy and regular. The feeding tray 151 in this embodiment may be a ratchet. Optionally, a plurality of receiving members (not shown) are uniformly arranged on the periphery of the feeding tray 151, and the configuration of the receiving members is similar to that of the first receiving groove 142, so that the objects 20 can be received.

In this embodiment, by providing the second receiving grooves 152 or receiving members distributed uniformly, the feeding assembly 150 can convey the objects 20 downstream at equal intervals under the condition that the feeding driving member drives the feeding tray 151 to rotate at a constant speed. In this way, other devices disposed downstream of the feeding channel 110 can stably receive the objects 20. According to the receiving efficiency of other downstream devices, the distribution quantity of the second receiving grooves 152 or receiving parts on the feeding tray 151 can be adjusted, and the rotating speed of the feeding tray 151 can also be adjusted to meet the feeding requirement and ensure that the feeding efficiency of the feeding mechanism is consistent with the receiving efficiency of other downstream devices.

In this embodiment, the first receiving groove 142 and the second receiving groove 152 may be arc-shaped, taking the object 20 as an example of a battery.

In this embodiment, the feeding mechanism 100 can match the rotation speed of the feeding tray 151 and the number of the second receiving grooves 152 by setting the rotation speed of the distribution tray 141 and the number of the first receiving grooves 142. Because a plurality of first receiving grooves 142 and a plurality of second receiving grooves 152 are respectively and uniformly arranged at the peripheries of the distributing tray 141 and the feeding tray 151, when one of the first receiving grooves 142 on the distributing tray 141 carries the object 20 to transfer to the receiving station 10, one of the second receiving grooves 152 on the feeding tray 151 just rotates 20 to the receiving station 10, so that the object 20 can sequentially circulate, and the circulation speed of the object 20 can be controlled by controlling the matching efficiency of the first receiving groove 142 and the second receiving groove 152 to be matched with downstream equipment for use.

Alternatively, to facilitate dispensing by dispensing assembly 140, infeed section 111 may be provided with a width through which only one article 20 passes; in order to better limit the movement of the objects 20 in the feeding channel 110 to the distributing assembly 140, the feeding section 111 may be provided with a fence at both sides, wherein a notch 114 is further formed on the fence at a position of the feeding section 111 corresponding to the distributing assembly 140 to allow the distributing tray 141 to enter the feeding section 111 through the notch 114 for performing a related action, so as to facilitate the first receiving groove 142 to receive the objects 20. Since the second receiving groove 152 of the feeding assembly 150 moves along a circle, the circulation section 112 can be configured as a circular arc track.

In a specific application scenario, when the matching efficiency of the material separating assembly 140 and the material feeding assembly 150 is inconsistent, the articles 20 may be stacked or jammed near the material receiving station 10. Based on this, the feeding mechanism 100 in this embodiment may further include a buffering assembly 130, and the buffering assembly 130 may be disposed in a region near the receiving station 10 for alleviating the accumulation or blockage of the articles 20 on the feeding channel 110.

Of course, in other embodiments, the buffer assembly 130 can be disposed at other positions of the material inlet channel 110. It is understood that the setting position and the number of the buffer assemblies 130 on the feeding channel 110 are not limited in this embodiment, and those skilled in the art can make adjustments according to actual situations.

For example, in a specific application scenario, when the separating assembly 140 and the feeding assembly 150 interface the objects 20, if the feeding assembly 150 does not completely receive the objects 20, the objects 20 are biased toward the separating assembly 140. As the distributing tray 141 rotates continuously, the objects 20 will be supported on the rail of the feeding channel 110 near the distributing assembly 140; at this time, the material separating assembly 140 is still delivering the objects 20 to the material feeding assembly 150, and the material feeding assembly 150 is still transferring the objects 20 to the downstream of the material feeding channel 110; as a result, the receiving station 10 can be subject to a build-up or jamming of articles 20.

Optionally, the buffering assembly 130 may be movably connected to the feeding channel 110 by splicing, and is used as a part of the feeding channel 110, so that the buffering assembly 130 can play a role of buffering when not pushed by the objects 20.

Further, referring to fig. 2 in conjunction with fig. 1, fig. 2 is a schematic diagram illustrating an operation of the buffer assembly 130 according to the present application. In the embodiment, when the objects 20 are jammed inside the feeding channel 110 to form a stack or a jam, the objects 20 will abut against the fence of the feeding channel 110 near the distributing member 140, and the objects 20 will be squeezed together to push the buffering member 130. Since the buffer assembly 130 is movably connected to the feeding channel 110, when the buffer assembly 130 is pushed by the object 20, the buffer assembly 130 moves away from the feeding channel 110. In one embodiment, after the buffer assembly 130 is pushed out by the misaligned articles 20, the feeding channel 110 is unblocked again, and the articles 20 received by the feeding assembly 150 can continue to move downstream along the feeding channel 110. In another embodiment, a detecting member (not shown) may be provided, and after the buffering assembly 130 is pushed, the detecting member can detect the change of the buffering assembly 130, and then transmit the information to the control system, and the control system sends an alarm to remind the operator to handle the piled or jammed object and to dredge the feeding channel 110 again. In another embodiment, after the buffering assembly 130 is pushed out by the dislocated objects 20, the original connection between the buffering assembly 130 and the feeding channel 110 forms a gap 113, and the stacked objects 20 can be discharged from the inside of the feeding channel 110 through the gap 113, so that the feeding channel 110 is unblocked again. After the stacked articles 20 are discharged, the buffer assembly 130 may be reconnected to the infeed channel 110, and the underlying articles 20 may continue to be conveyed upstream of the infeed channel 110 to downstream of the infeed channel 110.

Through the manner, the feeding mechanism 100 in the application can process the blocking condition and dredge the feeding channel 110 through the buffering assembly 130 when the objects 20 are stacked or blocked in the feeding channel 110, so as to continue to convey the subsequent objects 20, thereby reducing the influence of the stacking or blocking of the objects 20 on the conveying efficiency of the feeding mechanism 100.

Specifically, referring to fig. 1 and further referring to fig. 3, fig. 3 is a schematic diagram illustrating the connection between the buffer assembly 130 and the feeding channel 110 according to the present embodiment. In this embodiment, two ends of the buffering assembly 130 are respectively spliced with the fences of the feeding section 111 and the circulating section 112 of the feeding channel 110 near one side of the material distributing assembly 140. The first end 1301 of the buffering assembly 130 is movably connected to the circulation section 112, and the second end 1302 of the buffering assembly 130 is movably connected to the feeding section 111.

Optionally, the first end 1301 of the buffer assembly 130 may be provided with at least one protrusion, and a groove corresponding to the protrusion is provided at the joint of the feeding section 111 and the buffer assembly 130. The buffer assembly 130 and the feeding channel 110 are arranged in the splicing structure, so that the buffer assembly 130 can move; on the other hand, the buffer assembly 130 is guided to move, so that the buffer assembly 130 can only move along the splicing direction with the feeding channel 110, and the accuracy and stability of the position of the buffer assembly 130 are ensured.

Of course, in other embodiments, the second end 1302 of the cushioning member 130 may be configured to resemble a protrusion and a groove, which is not further limited in this embodiment. It can be understood that the splicing manner of the buffer assembly 130 and the feeding channel 110 in this embodiment is only one, and other types of splicing manners may be adopted in other embodiments as long as the splicing manner can achieve the movable connection and has a function of guiding the buffer assembly 130 to move in the splicing direction, and those skilled in the art can adjust the splicing manner according to the actual situation, and details are not described herein.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a feeding mechanism according to another embodiment of the present disclosure. In this embodiment, the feeding mechanism 200 may include an input channel 210 for conveying the objects 20, and a material distributing assembly 240, a buffering assembly 230 and an input assembly 250 sequentially disposed on the input channel 210. The material distributing assembly 240 is used for receiving the objects 20 conveyed from the feeding channel 210 and transferring the objects to the feeding assembly 250; the feeding assembly 250 is used for receiving the articles 20 transferred from the material distributing assembly 240 and driving the articles 20 to be conveyed to downstream equipment through the feeding channel 210; the buffer assembly 230 is movably connected to the feeding channel 210, and is used for handling a blockage situation and dredging the feeding channel 110 when the objects 20 are stuck in the feeding channel 210 and stacked or blocked, so as to allow the objects 20 to continuously move downstream in the feeding channel 110. The specific structure and connection relationship of the components of the feeding mechanism 200 can be referred to the previous embodiment, and will not be further described in this embodiment.

The difference between the present embodiment and the previous embodiment is that the buffering assembly 230 in the present embodiment further includes a buffering element 231 and a buffering reset element 232, and the buffering reset element 232 is connected to the buffering element 231 and is used for driving the buffering element 231 to reset after the object 20 is discharged. The buffer 231 is matched with the feeding channel 210 in a splicing manner and serves as a part of the feeding channel 210; the buffering reset member 232 further includes an elastic member 2321 and a fixing member 2322, and both ends of the elastic member 2321 are respectively connected to the buffering member 231 and the fixing member 2322. The elastic member 2321 is used for providing a restoring force for the buffer member 231 after the clamped object 20 is processed; the fixing member 2322 is used for providing a supporting point when the buffer member 231 is reset.

Optionally, the elastic member 2321 in this embodiment is in a compressed state and abuts against the buffer member 231. When the object 20 pushes the buffering member 231, the elastic member 2321 disposed between the fixing member 2322 and the buffering member 231 is further compressed until the object 20 is processed, the buffering member 231 loses the external force, and the elastic restoring force of the elastic member 2321 pushes the buffering member 231 to be matched with the feeding channel 210 again. In this embodiment, the elastic member 2321 may be a compression spring; the fixing member 2322 may be disposed on the main body of the feeding mechanism 200, or may be disposed on other devices, which is not further limited in this embodiment.

Compared with the previous embodiment, the feeding mechanism 200 of the present embodiment further includes a buffering reset member 232 in the buffering assembly 230, and the buffering reset member 232 can drive the buffering member 231 to reset quickly after the object 20 is processed, so as to further reduce the influence of the object 20 being stuck on the feeding assembly 250 and the separating assembly 240 to convey the subsequent object 20.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a feeding mechanism according to still another embodiment of the present disclosure. In this embodiment, the feeding mechanism 300 may include a feeding channel 310 for conveying the objects 20, and a material distributing assembly 340, a buffering assembly 330 and a feeding assembly 350 sequentially disposed on the feeding channel 310. The specific structure, function and connection relationship of the components of the feeding mechanism 300 can refer to any of the above embodiments, and will not be further described in this embodiment.

The present embodiment is different from any of the above embodiments in that the buffer assembly 330 in the present embodiment further includes a buffer 331, a buffer resetting member 332, and a guide member 333, and the guide member 333 is connected to the buffer 331 and the buffer resetting member 332. The guide member 333 may include a connection member 3331 and a stopper 3332. The connecting member 3331 connects the buffer member 331 and the elastic member 3321 of the buffer resetting member 332, respectively, and is rotatably connected to a rotation fulcrum. Therefore, when the buffering member 331 is pushed outward by the dislocated object 20, the buffering member 331 drives the connecting member 3331 to rotate around the rotation pivot, so that the buffering member 331 moves away from or approaches the feeding channel 310 in a swinging manner along the arc track.

When the objects 20 push the buffer 331, the buffer 331 moves along an arc track around the rotation pivot under the guidance of the connecting element 3331, so that the end of the buffer 331, which is engaged with the feeding channel 310, is spaced and forms a gap for allowing the objects 20 to pass through (see fig. 2). Thus, the jammed objects 20 can be accommodated in the gap to avoid the influence on the transportation of the subsequently conveyed objects 20 when the feeding channel 310 is blocked. The jammed item 20 can be removed manually or pushed directly from the gap by a subsequent item 20 out of the infeed channel 310.

In one embodiment, in order to minimize the volume of the feeding mechanism 300, the rotation point may be the motor shaft 343 of the material distributing assembly 340; at this time, the connecting member 3331 is rotatably connected to the motor shaft 343 via a bearing, so that the rotation of the motor shaft 343 does not affect the buffer member 331, and the passive motion of the buffer member 331 does not affect the motion of the material separating assembly 340.

Further, the position-limiting member 3332 is used for limiting the reset position of the buffer member 331. In an initial state, the connecting member 3331 may abut against the limiting member 3332; when the buffering member 331 is pushed by the dislocated object 20, the buffering member 331 drives the connecting member 3331 to rotate around the rotation pivot and to be away from the feeding channel 110; after the pushing force of the object 20 is lost, the elastic restoring force of the elastic element 2321 pulls the buffering element 331 to rotate reversely around the rotation pivot until the buffering element 331 abuts against the limiting element 3332 again. By providing the position-limiting member 3332, the position of the buffer member 331, which is finally engaged with the feeding channel 310 when the buffer member 331 is reset, can be limited, and the feeding channel 310 is not blocked by excessive resetting of the elastic restoring force of the elastic member 2321.

Optionally, the elastic member 3321 in this embodiment is in a stretched state. Thus, after the clamped object 20 is processed, the elastic member 3321 pulls the connecting member 3331, so that the buffer member 331 connected to the connecting member 3331 is engaged with the feeding channel 310 again. The position-limiting member 3332 can prevent the buffer 331 from being over-reset and exceeding the range of the feeding channel 310, thereby avoiding affecting the transportation of the subsequent objects 20. The elastic member 3321 in this embodiment may be a tension spring.

Optionally, the guiding member 333 in this embodiment may further include a detecting element 3333 for detecting the position of the buffering element 331. Specifically, the detecting element 3333 may be disposed on one side of the limiting element 3332, and a detecting end of the detecting element 3333 is opposite to the connecting element 3331 abutted against the limiting element 3332 and fixed on the main body of the feeding mechanism 300 through the fixing seat 3334. The detecting member 3333 can be a distance sensor for detecting the distance between the detecting member 3333 and the connecting member 3331, and transmitting the information to the control system, wherein the control system determines whether the buffering member 331 has completed the reset operation and is to be used as a part of the feeding channel 310 again. If the information detected by the detecting element 3333 is not satisfactory, it indicates that the buffering element 331 has not been reset, and the object 20 may still be in a jammed state, requiring operator intervention.

Of course, in other embodiments, the detecting element 3333 may also be disposed on the feeding channel 310 to detect whether a gap is formed between the buffering element 331 and the feeding channel 310 (see fig. 2), so as to determine whether the buffering element 331 is reset.

In an embodiment, the connection 3331 further includes a first sub-connection 33311, a second sub-connection 33312, and a third sub-connection 33313. The first sub-link 33311 is connected to the damper 431, the second sub-link 33312 is pivotally connected to the pivot and simultaneously connects the first sub-link 33311 and the third sub-link 33313, and the third sub-link 33313 is connected to the damper reset member 332. In the initial state, the third sub-connecting member 33313 abuts against the limiting member 3332; the detecting member 3333 may detect the position of the third sub-connecting member 33313 so as to know the position of the buffering member 331. As can be easily understood, the force direction of the third sub-connecting element 33313 is similar to the force direction of the buffer 331, so that the buffer resetting member 332 acts on the third sub-connecting element 33313 to finally reset the buffer 331.

When the object 20 is jammed, it pushes the buffer 331. When the pulling force of the buffer resetting member 332 and the pushing force of the object 20 reach a balance, or the distance set by the buffer 331 is too small, the object 20 is likely to be jammed between the buffer 331 and the feeding channel 310. At this time, the third sub-connection member 33313 may serve as a point of action of the human applied force. That is, when the object 20 is found to be jammed, the worker may make the buffer member 331 have a large distance by pressing the third sub-connecting member 33313, so that the jammed object 20 is smoothly discharged.

Optionally, the feeding mechanism proposed by the present application further comprises a stop assembly 360. The stop assembly 360 is disposed at the feeding section 311 for blocking the articles 20 from entering the feeding channel 310. As can be readily appreciated, when the apparatus is shut down or there is a need for shutting down, in order to prevent the objects 20 from entering the feeding mechanism and affecting the processing, the feeding channel 310 is blocked by the stopping assembly 360, which plays a role in blocking the objects 20 from entering the feeding channel 310.

Specifically, stop assembly 360 includes a stop 361 and a stop drive 362; in the non-blocking state, the stopping part 361 is far away from the feeding channel 310, the feeding channel 310 is smooth, and the objects 20 can be conveyed in the feeding mechanism; when it is desired to block the feeding channel 310, the stop driving member 362 drives the stop 361 to move toward the feeding channel 310, so that the stop 361 blocks the feeding channel 310 and blocks the objects 20 from entering the feeding channel 310. The stopping member 361 can be disposed on any side of the feeding section 311, and only needs to move towards the feeding channel 310 to block the feeding channel 310 when necessary, which is not limited in the present application.

In one embodiment, the feeding channel 310 includes a feeding section 311, and the feeding section 311 includes a first baffle 3111 and a second baffle 3112, the first baffle 3111 and the second baffle 3112 being disposed opposite to each other and forming a slot 3113 for transporting the objects 20.

Specifically, the stopper 361 is disposed on the first stopper 3111, and the stopper driving member 362 drives the stopper 361 to reciprocate between the first stopper 3111 and the second stopper 3112. When the stopper 361 penetrates from a side of the first shutter 3111, enters the feeding section 311, and abuts against a side of the second shutter 3112 opposite to the first shutter 3111, the stopper 361 can block the objects 20 from entering the feeding passage 310. Alternatively, the stop 361 in this embodiment may be a lever or a baffle, and the stop drive 362 may be a cylinder.

When the objects 20 are stacked or blocked too severely in the feeding channel 310 and cannot be processed by the buffering assembly 330, the worker can control the stopping driving member 362 so that the stopping member 361 extends into the feeding channel 310 from one side of the feeding section 310 and abuts against the other side of the feeding channel 310 to block the objects 20 from continuously entering the feeding channel 310, thereby preventing the objects 20 in the feeding channel 310 from being blocked too much and avoiding damaging the feeding mechanism 300.

In summary, the present application provides a feeding mechanism for conveying an object.
