[0045] Please refer to Figure 1-Figure 12The present embodiment is a counting and packaging device for sealing rings. The counting and packaging device 100 for sealing rings comprises a dividing plate 1, a plurality of carriers 2 arranged in equal angles on the dividing plate 1, and a loading station 30, a correction station 40 and a discharge station 50 arranged in sequence around the conveying direction of the dividing plate 1, each station being provided with a carrier 2 for transversely stacking sealing rings 200; a conveying mechanism 3 for conveying sealing rings 200, a feeding module 4 for sequentially pushing the sealing rings 200 on the conveying mechanism 3 to the carrier 2, and a counting sensor 6 arranged at the output end of the feeding module 4 are arranged at the loading station 30; a correction module 7 for correcting a plurality of sealing rings 200 on the carrier 2 is arranged at the correction station 40; a packaging mechanism 8 for simultaneously bagging a plurality of sealing rings, a discharge and conveying mechanism 9 for simultaneously conveying a plurality of corrected sealing rings 200 on the carrier 2 to the packaging mechanism 8, and a finished product conveying line 5 for conveying the packaged finished products on the packaging mechanism 8 are arranged at the discharge station 50.

[0046] A rotary drive motor 11 is disposed at the lower end of the indexing plate 1 to drive the indexing plate 1 to rotate. The rotary drive motor 11 drives the indexing plate 1 to rotate so that the carrier 2 on each station rotates to the next station in sequence. The rotary drive motor 11 is fixed on a frame 12 .

[0047] The conveying mechanism 3 includes a conveying channel 32 for conveying the sealing ring 200 in an upright state, a conveying line 31, a rolling channel connecting the conveying line 31 and the feeding module 4, and a direct vibration module 33 for driving the sealing ring 200 in the rolling channel to be conveyed forward, and the rolling channel is arranged obliquely so that the sealing ring 200 in the guide channel 34 can be smoothly conveyed to the feeding module 4. The conveying line 31 is conveyed by a transmission shaft and a transmission belt, and a guide channel 34 is arranged above the transmission belt of the conveying line 31 to keep the sealing ring 200 in an upright state, and the guide channel 34 is formed by a plurality of guide rods surrounded front and back; the guide channel 34 is connected to the rolling channel and has a conveying channel 32 formed inside for rolling a single sealing ring 200 in an upright state.

[0048] The feeding module 4 includes a receiving plate 43 connected to the end of the conveying channel 32, a first cylinder 42 that drives the receiving plate 43 to move forward and backward to realize that the receiving plate 43 is alternately connected to the conveying channel 32 and the carrier 2, a limiting blocking plate 47 that limits the end face of the sealing ring 200 and blocks the sealing ring 200 in the conveying channel 32 from continuing to be transported forward, and a second cylinder 48 that drives the limiting blocking plate 47 to push the sealing ring 200 onto the carrier 2; the upper surface of the receiving plate 43 is provided with a supporting groove 44 that supports the bottom of the sealing ring 200, and a limiting plate 45 that prevents the sealing ring 200 from falling is provided on the side opposite to the conveying channel 32, and a sensor 46 that detects whether the sealing ring 200 enters the supporting groove 47 is provided above. The counting sensor 6 is arranged below the middle of the limiting blocking plate 47 and the carrier 2 to prevent interference with the detection of the sensor 46. The position-limiting blocking plate 47 includes a position-limiting portion 471 disposed at the front end to limit the end face of the sealing ring 200 and a blocking portion 472 disposed at the side to block the sealing ring 200 in the conveying channel 32 from continuing to be conveyed forward. When the receiving plate 43 is connected to the conveying channel 32, the position-limiting portion 471 is aligned with one side of the conveying channel 32, so that when the sealing ring 200 enters the supporting groove 44, the end face of the sealing ring 200 is just limited on the position-limiting portion 471 to prevent the sealing ring 200 from tipping over. When the second cylinder 48 drives the position-limiting blocking plate 47 to push, the position-limiting portion 471 pushes the sealing ring 200 onto the carrier 2. The sensor 46 can adjust the angle so as to detect whether there is a sealing ring 200 in the supporting groove 44.

[0049] The feeding module 4 further includes a feeding frame 41 , on which a first slide rail 411 is disposed, and a receiving plate 43 is slidably disposed on the first slide rail 411 via a first sliding block 431 .

[0050] The process of the sealing ring 200 on the conveying mechanism 3 entering the carrier 2 is as follows: the conveying mechanism 3 continuously outputs a single sealing ring 200 in an upright state, the sealing ring 200 enters the support groove 44 on the receiving plate 43 from the conveying flow channel 32 and is restricted by the limiting plate 45 without falling. When the sensor 46 detects that there is a sealing ring 200 on the receiving plate 43, the first cylinder 42 retracts to drive the receiving plate 43 to communicate with the carrier 2, and the second cylinder 48 drives the limiting blocking plate 47 to push the sealing ring 200 on the receiving plate 43 onto the carrier 2. At the same time, the blocking portion 472 on the side of the limiting blocking plate 47 blocks the sealing ring 200 on the receiving plate 43. The sealing ring 200 in the conveying channel 32 continues to be conveyed forward. At the same time, when the sealing ring 200 is pushed to the carrier 2, the counting sensor 6 senses and detects the sealing ring 200 and counts it; after the sealing ring 200 is pushed onto the carrier 2, the second cylinder 48 retracts to drive the limit blocking plate 47 to retract, and the blocking part 472 on the side of the limit blocking plate 47 retracts synchronously. At the same time, the first cylinder 42 extends out to drive the receiving plate 43 to connect with the conveying channel 32. The receiving plate 43 continues to receive the next sealing ring 200 on the conveying channel 32 and allows the next sealing ring 200 to enter the carrier 2.

[0051] The carrier 2 includes a pair of first support rods 21 arranged on the dividing plate 1 and supporting the sealing ring 200, and a clamping rod 222 movably arranged above the first support rods 21 and pressing the sealing ring 200. The first support rods 21 and the clamping rods 222 together form a transverse storage bin 22, and the opening of the bin 22 faces radially outward to receive the sealing ring 200 on the receiving plate 43.

[0052] One end of the first support rod 21 is fixed on the dividing plate 1 and the other end is cantilevered out of the dividing plate 1; a stop block 212 is provided on the first support rod 21 on the inner side of the silo 22, and the inner end of the clamping rod 222 is axially movable with a first end limit block 223, and the outer end is fixedly provided with a second end limit block 228.

[0053] A contoured slot 211 for supporting the lower side of the sealing ring 200 is formed between a pair of first support rods 21, a first end stopper 223 is installed on the clamping rod 222 through a linear bearing 227, and the lower end of the first end stopper 223 extends vertically downward from the silo 22 into the contoured slot 211, and the lower side of the sealing ring 200 is supported in the contoured slot 211. For sealing rings 200 of different diameters, since the lower side of the sealing ring 200 is an arc structure, the arc-shaped periphery at different positions can be inserted into the contoured slot 211, so it can be applied to sealing rings 200 of different diameters. Two first support rods 21 are provided to support the bottom of the sealing ring, and the silo 22 provided can move up and down and press against the upper side of the sealing ring 200, so the provided carrier 2 can be applied to sealing rings of different diameters, and has strong versatility.

[0054] The height of the stop block 212 is higher than the height of the first support rod 21, so that multiple sealing rings 200 can be pushed into the silo 22. The stop block 212 stops the lower end face of the sealing ring 200 that first enters the silo 22, and the first end stop block 223 stops the upper end face of the sealing ring 200 that first enters the silo 22. The stop block 212 and the first end stop block 223 work together to stop the sealing ring that first enters the silo 22 to prevent the sealing ring from tipping over. The second end stop block 228 stops the end face of the sealing ring 200 that last enters the first support rod 21. The stop block 212 and the first end stop block 223 stop the inner end face of the sealing ring, and the second end stop block 228 stops the outermost sealing ring. The three together achieve the function of limiting the front and rear end faces of multiple sealing rings 200.

[0055] The carrier 2 also includes a first support frame 221 disposed on the indexing plate 1, a mounting frame 224 is slidably disposed on the first support frame 221, one end of the clamping rod 222 is fixed on the mounting frame 224, and the mounting frame 224 is pressed downward by the elastic component so that the clamping rod 222 remains in a clamped state. A second slide rail 2211 is disposed on the first support frame 221, and the mounting frame 224 is slidably disposed on the second slide rail 2211 through a second slider 2241. The elastic component includes a guide rod 226 disposed on the mounting frame 224, a spring sleeved on the outer periphery of the guide rod 226, and a spring stopper 229 disposed on the upper end surface of the spring and fixed on the first support frame 221, the lower end of the spring abuts on the mounting frame 224, and the upper end abuts on the spring stopper 229.

[0056] A driving module is provided at the loading station 30 and the unloading station 50 to drive the clamping rod 222 to open upward, and the driving module includes a roller 2242 disposed on the mounting frame 224 and a driving member that drives the roller 2242 to move upward.

[0057] In this embodiment, the driving member is a cam 225 fixedly arranged above the indexing plate 1. The cam 225 is fixed to the frame 12 through a plurality of support rods, and the cam 225 extends upward from the middle of the indexing plate 1. Since the clamping rod 222 needs to be opened upward at the loading station 30 and the unloading station 50, so that the conveying mechanism 3 can push the sealing ring onto the silo 22, or the unloading and handling mechanism 9 can remove the sealing ring 200 from the silo 22, a rolling track 2251 higher than the surface of the cam 225 is provided on the cam 225, and the rolling track 2251 forms a height difference with the surface of the cam 225. The rolling track 2251 covers the loading station 30 and the unloading station 50. When the carrier 2 rotates with the indexing plate 1, when the roller 2242 passes through the rolling track 2251, it is lifted upward by the rolling track 2251, so that the clamping rod 222 is lifted upward and opened. The rolling track 2251 and the surface of the cam 225 are connected by a guiding slope to facilitate the roller 2242 to enter the surface of the cam 225 from the rolling track 2251 and enter the correction station 40. The clamping rod 222 is pressed downward by the elastic component so that the clamping rod 222 remains in a clamped state. The clamping rod 222 is pressed downward on the sealing ring 200 and together with the correction module 7 realizes the correction action of the sealing ring 200.

[0058] In this embodiment, the rolling track 2251 extends from the unloading station 50 to the loading station 30 along the conveying direction of the indexing plate 1. After the sealing ring 200 in the carrier 2 on the unloading station 50 is taken away, the indexing plate 1 drives the carrier 2 to rotate at the same time, and at the same time, the roller 2242 rolls on the rolling track 2251 to enter the loading station 30, and the spring of the elastic component is compressed. At this time, the clamping rod 222 is in an upwardly opened state, and the conveying mechanism 3 continues to push the sealing ring 200 into the silo 22, and the sealing ring 200 pushed later pushes the sealing ring 200 that has been pushed in front to the indexing plate in sequence. 1 is pushed from the center side. When the sealing ring 200 to be pushed reaches the set number, the indexing plate 1 rotates, and at the same time, the roller 2242 enters the surface of the swallowing cam 225 from the rolling track 2251 through the guide slope. At this time, the spring of the elastic component is stretched, and the clamping rod 222 elastically presses downward on the upper side of the sealing ring 200. The second end limit block 228 limits the end face of the sealing ring 200 that finally enters the first support rod 21. The indexing plate 1 continues to rotate, and the carrier 2 enters the return station 40. The clamping rod 222 and the return module 7 together realize the return action of the sealing ring 200.

[0059] In other embodiments, the driving member is configured to be cylinder-driven or motor-driven. When at the loading station 30 and the unloading station 50, the cylinder-driven or motor-driven clamping rod 22 opens upward to facilitate loading and unloading. At the correction station 40, the cylinder-driven or motor-driven clamping rod 22 moves downward, thereby realizing the elastic clamping action of the clamping rod 222 on the sealing ring 200.

[0060] Since the sealing rings 200 pushed onto the carrier 2 may be offset in position or the spacing between the sealing rings 200 may be non-uniform, a correction module 7 is provided to correct the sealing rings 200 before packaging the sealing rings to ensure the quality of packaging.

[0061] The correction module 7 includes a correction block 71 that pushes the first end limit block 223, a third cylinder 72 that drives the correction block 71 to push the first end limit block 223 toward the second end limit block 228 to achieve end face correction, and a second support frame 73 that fixes the third cylinder 72. The upper end of the first end limit block 223 extends upward and overlaps with the correction block 71 in the vertical height, so that the correction block 71 can contact and push the first end limit block 223 when moving forward and backward.

[0062] When the dividing plate 1 rotates and the carrier 2 enters the alignment station 40, the roller 2242 is on the second rolling track 2252. At the same time, the spring of the elastic component is stretched, the clamping rod 222 is in a low position and elastically pressed on the upper side of the sealing ring 200, and the second end limit block 228 on the clamping rod 222 limits the end face of the sealing ring 200 that finally enters the first support rod 21. The third cylinder 72 drives the alignment block 71 to push the first end limit block 223 toward the second end limit block 228, and laterally compresses the set number of horizontally stacked sealing rings 200 to achieve alignment of the upper and lower sides and the front and rear end faces.

[0063] The material unloading and handling mechanism 9 includes a linear drive motor 91, a first support plate 92 driven by the linear drive motor 91 to move left and right, a fourth cylinder 93 fixed on the first support plate 92, a second support plate 94 driven by the fourth cylinder 93 to move up and down, a second support rod 95 arranged on the second support plate 94 and supported at the bottom of the sealing ring 200, a first clamping rod 96 fixed on one side of the second support plate 94 and clamped on one end face of the sealing ring 200, a second clamping rod 98 movably arranged on the other opposite side of the second support plate 94 and capable of extending into the silo 22 and clamped on the other opposite end face of the sealing ring 200, and a fifth cylinder 97 for driving the second clamping rod 98 to move left and right to realize the clamping action.

[0064] In this embodiment, since a first end limit block 223 is provided at the end face of the sealing ring 200 on the inner side of the dividing plate 1 to limit and correct the end face of the sealing ring 200, the end face of the sealing ring 200 is blocked by the first end limit block 223. Therefore, the clamping assembly is clamped at the end face of the sealing ring 200 on the inner side of the dividing plate 1, and the first clamping rod 96 is clamped at the end face of the outermost sealing ring of the dividing plate 1. Then the driving shaft of the fifth cylinder 97 retracts to drive the second clamping rod 98 to move toward the side of the first clamping rod 96 so that the first clamping rod 96 and the second clamping rod 98 are clamped at the two end faces of the sealing ring 200 at the same time. Therefore, an avoidance opening 99 for avoiding the first end limit block 223 is provided in the middle of the second clamping rod 98 to facilitate the left and right movement of the second clamping rod 98 to clamp the end face of the sealing ring 200.

[0065] The action of the unloading and handling mechanism 9 for clamping and handling is as follows: the linear drive motor 91 drives the first support plate 92 to move to the bottom of the carrier 2 of the unloading station 50, the fourth cylinder 93 drives the second support plate 94 to drive the second support rod 95, the first clamping rod 96 and the second clamping rod 98 to move upward at the same time, the second support rod 95 extends into the contoured groove 211 to support the bottom of the sealing ring 200, the first clamping rod 96 extends into the end face of the right side of the sealing ring 200, the first clamping rod 96 extends into the silo 22, and then the drive shaft of the fifth cylinder 97 retracts to drive the second clamping rod 98 to move upward. The rod 98 moves toward the side of the first clamping rod 96 so that the first clamping rod 96 and the second clamping rod 98 are clamped on the two end surfaces of the sealing ring 200 at the same time, and the linear drive motor 91 drives the first support plate 92 to drive the first clamping rod 96 and the second clamping rod 98 to move the sealing ring 200 to the right away from the carrier 2, and the fourth cylinder 93 drives the second support plate 94 to drive the second support rod 95, the first clamping rod 96 and the second clamping rod 98 to move downward at the same time, and under the drive of the linear drive motor 91, the sealing ring 200 is transported to the packaging mechanism 8 for bagging and packaging operations.

[0066] The packaging mechanism 8 uses a packaging bag to package a plurality of transversely stacked sealing rings. This technology is in the prior art and will not be described in detail here.

[0067] When the counting and packaging device 100 for sealing rings provided by the present invention is applied: the conveying mechanism 3 continuously outputs a single sealing ring 200 in an upright state, and the sealing ring 200 enters the support groove 44 on the receiving plate 43 from the conveying flow channel 32 and is restricted by the limiting plate 45 and does not fall. When the sensor 46 detects that there is a sealing ring 200 on the receiving plate 43, the first cylinder 42 retracts to drive the receiving plate 43 to communicate with the carrier 2, and the second cylinder 48 drives the limiting blocking plate 47 to push the sealing ring 200 on the receiving plate 43 onto the carrier 2. At the same time, the limiting blocking plate The blocking portion 472 on the side of 47 blocks the sealing ring 200 in the conveying flow channel 32 from continuing to be conveyed forward. At the same time, when the sealing ring 200 is pushed to the carrier 2, the counting sensor 6 senses and detects the sealing ring 200 and counts it; after the sealing ring 200 is pushed to the carrier 2, the second cylinder 48 retracts to drive the limit blocking plate 47 to retract, and the blocking portion 472 on the side of the limit blocking plate 47 retracts synchronously. At the same time, the first cylinder 42 extends to drive the receiving plate 43 to communicate with the conveying flow channel 32, and the receiving plate 43 continues to receive the next sealing ring on the conveying flow channel 32. The sealing ring 200 is stopped by the stop block 212, and the next sealing ring 200 is put on the carrier 2. When the sealing rings 200 in the silo 22 reach the set number, the stop block 212 stops the lower end face of the sealing ring 200 that first enters the silo 22, and the first end limit block 223 limits the upper end face of the sealing ring 200 that first enters the silo 22. The stop block 212 and the first end limit block 223 work together to limit the sealing ring that first enters the silo 22. The indexing plate 1 rotates, and at the same time, the roller 2242 is guided by the rolling track 2251. The inclined surface enters the surface of the swallowing cam 225. At this time, the spring of the elastic component is stretched, and the pressing rod 222 is elastically pressed downward on the upper side of the sealing ring 200. The second end limit block 228 limits the end face of the sealing ring 200 that finally enters the first support rod 21. The indexing plate 1 continues to rotate, and the carrier 2 enters the return station 40. The third cylinder 72 drives the return block 71 to push the first end limit block 223 toward the second end limit block 228, and the set number of horizontally stacked sealing rings 200 are transversely pressed to realize the return of the upper and lower sides and the front and rear end faces.After being adjusted, the indexing plate 1 continues to rotate, and at the same time, the roller 2242 enters the rolling track 2251 from the surface of the cam 225 through the guide slope, the clamping rod 222 opens upward, and the linear drive motor 91 drives the first support plate 92 to move to the bottom of the carrier 2 of the unloading station 50. The fourth cylinder 93 drives the second support plate 94 to drive the second support rod 95, the first clamping rod 96 and the second clamping rod 98 to move upward at the same time, and the second support rod 95 extends into the silo 22 to support the bottom of the sealing ring 200, and the first clamping rod 96 extends into the end face of the right side of the sealing ring 200 in the silo 22, and then the drive shaft of the fifth cylinder 97 retracts to drive The second clamping rod 98 moves toward the first clamping rod 96 so that the first clamping rod 96 and the second clamping rod 98 are clamped at both end surfaces of the sealing ring 200 at the same time. The linear drive motor 91 drives the first support plate 92 to drive the first clamping rod 96 and the second clamping rod 98 to move the clamped sealing ring 200 to the right so as to leave the carrier 2. The fourth cylinder 93 drives the second support plate 94 to drive the second support rod 95, the first clamping rod 96 and the second clamping rod 98 to move downward at the same time, and under the drive of the linear drive motor 91, the sealing ring 200 is transported to the packaging mechanism 8 for bagging and packaging operations, and is output through the finished product conveyor line 5 after packaging. ;

[0068] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
