Referring to fig. 1, a material separating device is provided in an embodiment, and is applied to a conveying flow channel 101 to separate materials 4 on the conveying flow channel 101. The material separating device comprises a limiting mechanism and a driving unit which are arranged on the base 100. The limiting mechanism is a connecting rod and comprises a connecting part connected to the conveying runner 101, two arms extending out of the connecting part, a front arm 211 and a rear arm 222, and a front limiting piece 212 connected to the front arm 211 and the rear limiting piece 222 connected to the rear arm 221 respectively. The front and the rear are that, in the conveying direction of the conveying flow channel 101, the same material arrives at the rear first, and the direction of the same material flow is the front, that is, the material 4 is conveyed from the rear to the front. One end of the driving unit is connected to the conveying flow channel 101, and the other end of the driving unit is connected to the limiting mechanism to drive the limiting mechanism to move. The structure is simple in structure, low in cost and easy to replace elements and maintain, and only a connecting rod and a drive are added in the conveying flow channel 101. Meanwhile, the notch 102 is formed in the conveying runner 101, and the front limiting piece 201 or the rear limiting piece 222 protrudes into the conveying runner 101 from the notch 102, so that the material distribution device is allowed to be arranged at a height not higher than that of the conveying runner 101, even under the conveying runner 101, and space is saved.

In the above embodiments, the base 100 is provided integrally with the conveying runner 101, and the conveying runner 101 refers to its entirety. Of course, the base may be provided separately from the conveying flow path 101, and in this case, the position of the position limiting mechanism may be adjusted conveniently.

The conveying flow channel 101 bears materials and provides position reference for the driving unit and the limiting mechanism, the materials 4 are operation objects, the limiting mechanism is an operation mechanism, the driving unit belongs to a control mechanism, and the front limiting piece 212 and the rear limiting piece 222 of the limiting mechanism are controlled to swing in the conveying flow channel 101 so as to control the movement or stop of the materials 4 in the conveying flow channel 101. In the material conveying direction, the front limiting member 212 and the rear limiting member 222 are spaced from each other at a distance of one or more material sizes or slightly less than one material size, when the front limiting member works, the materials are drawn together to determine the specific position of the operated object, then the front limiting member 212 is retracted, the rear limiting member 222 works, so that the second or more than second group of materials 4 still keep stopping, and the first or more than second group of materials are discharged, as shown in fig. 2, namely, the separated materials 401. In order to make the front limiting member 212 and the rear limiting member 222 operate continuously and realize synchronous separation, the front limiting member 212 and the rear limiting member 222 are fixed on the same connecting rod, namely the front arm 211 and the rear arm 221 of the limiting mechanism, and after the position of the front limiting member 212 is determined, the position of the rear limiting member 222 is also determined, so that only the relative positions of the front limiting member 212 and the rear limiting member 222 need to be adjusted.

In an embodiment, referring to fig. 1, the connection manner of the limiting mechanism and the conveying runner 101 is a rotational connection, the connection portion is a rotation portion 201, and the driving unit acts on the front arm 211 or the rear arm 221 with the rotation portion 201 as a fulcrum to drive the front arm 211 or the rear arm 221 to rotate, so as to drive the front limiting member 212 and the rear limiting member 222 to swing in the conveying runner 101.

The distance between the front stopper 212 and the rear stopper 222 in the conveying direction of the conveying flow path 101 is generally a distance of an integer number of material sizes, but the range is not limited. The "distance" hereinafter refers to a distance in the conveying direction of the conveying flow path 101. The tolerance to the distance is different due to different shapes of the materials, for example, for a cylindrical battery, the tolerance range can reach five material sizes of positive and negative zero points; for the materials of the rectangular column, the tolerance range is almost zero; for materials with chamfers or fillets, the tolerance range depends on the size of the chamfers or fillets. If one of the right-angled sides of the right-angled triangular material is in contact with the conveying channel 101 and the other right-angled side is directed forward, the distance between the front stopper 212 and the rear stopper 222 may not be limited within one material.

In addition, according to the working interval between the front limiting piece 212 and the rear limiting piece 222, that is, the time interval in which no limiting piece is inserted in the conveying flow channel 101, and the conveying speed of the material 4, the distance between the front limiting piece 212 and the rear limiting piece 222 should be correspondingly shortened by × (═ vdt, where v denotes the instantaneous speed in the aforementioned time interval, t denotes the time, and the integration range is from the interval time to the end of the interval time.

When the shortened distance is less than the tolerant distance, the adjustment is not needed; however, when the shortened distance is greater than the tolerant distance, at least the shortened distance should be adjusted.

In short, in the conveying direction of the conveying flow channel 101, the distance between the front limiting member 212 and the rear limiting member 222 is such that when the front limiting member 212 leaves the limiting position and the rear limiting member 222 is inserted into the limiting position, the material distributing device just discharges the set number of separated materials 401, and the blocked materials 4 are not damaged; alternatively, the rear stopper 222 is inserted between the materials 4 when the front stopper 212 leaves the stopping position.

There may be exceptions to the above description of the distance between the front 212 and rear 222 stops. In one embodiment, when the rear stopper 222 is positioned above the material 4, i.e., spatially, with respect to the side of the material 4 contacting the bottom of the conveying flow channel 101, it is sufficient that the distance between the front stopper 212 and the rear stopper 222 is greater than or equal to one dimension of the material 4. In order to avoid the rear limiting piece 222 from damaging the material 4, a buffer can be assembled on the rear limiting piece 222. For cylindrical shapes of the materials 4, the distance between the front stopper 212 and the rear stopper 222 is greater than or equal to the size of zero five materials 4; similarly, for a material 4 having a chamfered or rounded shape, the distance between the front stop 212 and the rear stop 222 is greater than or equal to the size of one material 4 minus the width of the chamfer or radius. This embodiment allows more room for tolerance for the distance between the front 212 and rear 222 stops.

In this embodiment, referring to fig. 1, a notch 102 is provided at the bottom of the conveying flow channel 101; the rear limiting member 222 is located below the bottom of the conveying flow channel 101 and can extend into the conveying flow channel 101 from the notch 102, so as to block the material 4 in the conveying flow channel 101. Meanwhile, the front limiting piece 212 is located above the material 4 in the conveying flow channel 101, and the two limiting pieces are separately arranged, that is, the front limiting piece 212 and the rear limiting piece 222 respectively extend into the conveying flow channel 101 from two opposite sides relative to the conveying flow channel 101, so as to fully ensure the order of material distribution operation.

Similarly, the upper and lower positions of the front stopper 212 and the rear stopper 222 can be exchanged, and the same technical effect can be achieved, that is, the front stopper 212 is located below the bottom of the conveying flow channel 101 and can extend into the conveying flow channel 101 from the notch 102, so as to block the material 4 in the conveying flow channel 101. While the rear stop 222 is located above the material 4 in the conveying flow channel 101.

In addition to the above embodiments, a case where the front arm 211 and the rear arm 221 are located on the same side as the rotating portion 201 will be described. When the rotating part 201 is located in front of the front arm 211 and the rear arm 221, the rear arm 221 is longer than the front arm 211, so that a zigzag arm is provided, in the conveying direction of the conveying flow channel 101, the rotating part 201 is provided at the front end of the zigzag arm, the rear stopper 222 is provided at the rear end of the zigzag arm, and the front stopper 212 is provided at a turning point on the zigzag arm closest to the rotating part 201. Similarly, when the rotating part 201 is located behind the front arm 211 and the rear arm 221, the front arm 211 is longer than the rear arm 221, a zigzag arm is provided, in the conveying direction of the conveying flow channel 101, the rotating part 201 is arranged at the rear end of the zigzag arm, the front stopper 212 is arranged at the front end of the zigzag arm, and the rear stopper 222 is arranged at a turning position closest to the rotating part 201 on the zigzag arm. The front limiting piece 212 and the rear limiting piece 222 do not simultaneously perform blocking action or release, so that the material distributing operation is stable and orderly.

In order to further reduce the cost, referring to fig. 1, the driving unit is an inexpensive cylinder 3, and the cylinder 3 has opposite ends, one end of which is connected to the conveying flow passage 101 and the other end of which is connected to the rear arm 221.

Specifically, one end of the cylinder 3 is rotatably connected to the conveying flow channel 101, and the other end is rotatably connected to the rear arm 221; or, the rear arm 221 is provided with a guide rail or a guide groove, one end of the cylinder 3 is clamped on the guide rail or the guide groove on the rear arm 221, and the other end is rotatably connected to the conveying flow channel 101; or, a guide rail or a guide groove is arranged on the conveying flow channel 101, one end of the cylinder 3 is clamped on the guide rail or the guide groove on the conveying flow channel 101, and the other end is rotatably connected to the rear arm 221; or, the conveying flow channel 101 and the rear arm 221 are provided with guide rails or guide grooves, one end of the cylinder 3 is clamped on the guide rails or the guide grooves on the conveying flow channel 101, and the other end is clamped on the guide rails or the guide grooves on the rear arm 221.

In the embodiment, referring to fig. 1, a support member is fixedly connected to the bottom of the conveying flow channel 101, and one end of the cylinder 3 is rotatably connected to the support member, and the other end is rotatably connected to the rear arm 221 of the limiting mechanism. The support member is provided to provide a position for installing the transfer chute 101, and since the rear arm 221 is located at a short distance from the support member, the other end of the cylinder 3 is rotatably connected to the rear arm 211 for space saving and efficiency improvement. When the output end of the cylinder 3 contracts, the front arm 211 is lowered to drive the front limiting piece 222 to descend into the conveying channel of the conveying flow channel 101, so that the material 4 is blocked; when the output end of the cylinder 3 extends, the rear arm 221 is jacked up, so that the rear stopper 222 extends into the notch 102 to block the material 4, and at the same time, the front stopper 212 is lifted to discharge the separated material 401. In the process, the angle of the cylinder 3 relative to the limiting mechanism and the conveying flow channel 101 changes, a certain angle deviation is generated, and the rotary connection is used for assisting the process to be smoothly carried out.

Optionally, the driving unit is a cam motor, and the cam motor is composed of a motor and a cam connected to the output end of the motor; the motor of the cam motor is fixedly connected to the conveying flow channel 101, and the rim of the cam is movably connected to the rear arm 221 or the front arm 211. The cam motor is fixed relative to the delivery flow path 101, and the probability of occurrence of malfunction can be further reduced according to the principle of the razor.

Specifically, the rim of the cam can be connected with the limiting mechanism in an abutting connection or sliding connection mode. The collision connection means that the flange of the cam is collided on the front arm 211 or the rear arm 221 of the limiting mechanism, when the motor rotates, the cam can lift the limiting mechanism, and then returns to the initial state under the action of gravity, so that the material distribution operation is completed. Furthermore, in order to ensure the stability of connection, a guide rail or a guide groove is arranged on the limiting mechanism, and the cam is clamped on the guide rail or the guide groove, so that the stability is ensured.

In one embodiment, the material distribution device comprises a conveying flow channel 101, a limiting mechanism and a driving unit. The limiting mechanism is a connecting rod and comprises a transmission part connected to the conveying runner 101, two arms extending out of the transmission part, a front arm 211 and a rear arm 222, wherein a front limiting piece 212 is connected to the front arm 211, and a rear limiting piece 222 is connected to the rear arm 221. The front and the rear are that, in the conveying direction of the conveying flow channel 101, the same material arrives at the rear first, and the direction of the same material flow is the front, that is, the material 4 is conveyed from the rear to the front. One end of the driving unit is connected to the conveying flow channel 101, and the other end of the driving unit is connected to the limiting mechanism to drive the limiting mechanism to move. The structure is simple in structure, low in cost and easy to replace elements and maintain, and only a connecting rod and a drive are added in the conveying flow channel 101.

Specifically, the transmission part is slidably connected to the conveying flow path 101, and the sliding direction has a component perpendicular to the conveying direction of the conveying flow path 101. The movement of the transmission part in the direction perpendicular to the conveying direction of the conveying flow channel 101 drives the front stopper 212 and the rear stopper 222 to enter or leave the conveying channel of the conveying flow channel 101. If the component does not exist, the front stopper 212 and the rear stopper 222 are always inside or outside the conveying passage of the conveying flow passage 101 no matter how they move, and the two actions of blocking and releasing the material 4 cannot be performed.

Optionally, the drive unit is a dc motor. The direct current motor is fixedly connected to the conveying flow channel, and the output end of the direct current motor is connected with the front arm 211 or the rear arm 222 and drives the limiting mechanism to move.

Specifically, a tooth structure is arranged on the transmission part of the limiting mechanism, and the tooth structure is meshed with a gear at the output end of the direct current motor, so that the front limiting piece 212 and the rear limiting piece 222 are driven to enter or separate from the conveying channel of the conveying flow channel 101.

Optionally, a notch 102 is formed at the bottom of the conveying flow channel 101; the rear limiting member 222 is located below the bottom of the conveying flow channel 101 and can extend into the conveying flow channel 101 from the notch 102, so as to block the material 4 in the conveying flow channel 101. Meanwhile, the front limiting piece 212 is positioned above the material 4 in the conveying flow channel 101, and the front limiting piece 212 and the rear limiting piece 222 are separately arranged to fully ensure the ordering of material distribution operation.

Specifically, the direct current motor is connected with a pulse power supply, and the pulse power supply can output positive potential pulses and negative potential pulses of a certain level. Alternatively, the negative potential pulse causes the direct current motor to rotate reversely, drives the limiting mechanism to move along the lower part of the material 4, causes the front limiting piece 212 to block, releases the rear limiting piece 222, and the positive potential pulse causes the direct current motor to rotate normally, drives the limiting mechanism to move along the upper part of the material 4, causes the front limiting piece 212 to release, releases the rear limiting piece 222 to block, and separates the separated material 401; or, the positive potential pulse makes the direct current motor rotate forward to drive the limiting mechanism to move along the lower part of the material 4, so that the front limiting piece 212 blocks the rear limiting piece 222, and the negative potential pulse makes the direct current motor rotate backward to drive the limiting mechanism to move along the upper part of the material 4, so that the front limiting piece 212 blocks the rear limiting piece 222, and the separated material 401 is separated.

Optionally, a front limiting hole and a rear limiting hole are arranged on two sides of the conveying flow channel 101, the front limiting piece 212 extends into the front limiting hole 222, and the rear limiting piece 222 extends into the rear limiting hole; the transmission part is connected to a driving unit fixedly provided on the conveying flow passage 101.

The transmission part can adopt one of the following two modes: the transmission part is connected to the conveying flow channel 101 in a sliding manner, is higher than the conveying channel of the conveying flow channel 101 or lower than the conveying channel of the conveying flow channel 101, and cannot intersect with the conveying channel of the conveying flow channel 101; or directly connected with the driving unit, and the transmission part is positioned higher than the conveying channel of the conveying flow channel 101 or lower than the conveying channel of the conveying flow channel 101 and does not intersect with the conveying channel of the conveying flow channel 101.

In one embodiment, the driving unit is a cylinder 3. The output end of the cylinder 3 is connected with the transmission part. The cylinder 3 is arranged coaxially with the transmission part.

Referring to fig. 2, when the apparatus is operated, the apparatus is initially in an initial state in which the front stopper 212 is blocked in the conveyance path of the conveyance path 101 and the rear stopper 222 is out of the conveyance path, and is released. The material 4 is continuously conveyed forward until the material 4 is directly or indirectly blocked by the front stopper 212, accumulated and arranged in the conveying flow channel 101, and the position of each material 4 is determined due to the fixed size of each material 4.

At this point, the cylinder 3 extends to block the rear limiting member 222 in the conveying channel, the front limiting member 212 is sent out of the conveying channel, the material 4 behind the rear limiting member 222 is still blocked, and the separated material 401 originally between the front limiting member 212 and the rear limiting member 222 is released and separated out.

Then, the cylinder 3 contracts and the apparatus returns to the initial state.
