[0002] In the industrial field, many times need to feed the next work by feeding device, and the vibrating disc and the feeder are the commonly used feeding devices. Before the feeding device, the material needs to be counted and determined, that is, the counting.

[0003] In the food industry packaging industry, the counting device and the feeding device are separated. The counting device is arranged before the feeding device, and the to-be-packaged material is counted to a specific number before being transferred to the feeding device for feeding to the next process.

[0004] In the above-mentioned technology, for the fragile flaky food, the more the devices are transferred into, the higher the possibility of food fragmentation is, and the conventional vibrating disc and feeder accelerate the fragmentation of the fragile food. In addition, high-grade flaky fragile food packaging requires that the flaky food be arranged in order and that the product in each package have a specific number. Therefore, it is necessary to provide a feeding device which has a simple transfer process, no vibration, convenient counting, and orderly arrangement of to-be-packaged materials. SUMMARY

[0005] In order to facilitate counting and arrange the to-be-packaged materials in order through as few processes as possible, the present application provides a multi-channel counting and feeding device, which is implemented by adopting the following technical scheme.

Therefore, one to-be-packaged material corresponds to one counting yoke, one counting single shaft, one counting tooth, and one counting sensor, and the counting sensor will count once.

[0015] By adopting the above technical scheme, as many point number single shafts as there are on the point number roller, the point number roller can provide as many to-be-packaged objects as the number of the point number single shafts that complete one rotation. The arrayed through holes can accommodate the arrayed point number single shafts, so that the point number roller can stably and uniformly feed the to-be-packaged objects.

[0018] Preferably, the control fork sliding groove is an irregular closed ring.

[0019] By adopting the above technical solution, the shape of the irregular ring can ensure the rotation of the point counting single shaft. The distance between the control fork sliding groove and the center of the control fork fixed disc changes from large to small, and the rotation direction of the control fork single shaft is opposite to the revolution direction of the point counting single shaft around the point counting general shaft. The distance between the control fork sliding groove and the center of the control fork fixed disc changes from small to large, and the rotation direction of the control fork single shaft is the same as the revolution direction of the point counting single shaft around the point counting general shaft.

[0020] Preferably, the point counting disc is arranged on the outer side of the control fork fixed disc away from the point counting turntable.

Therefore, one to-be-packaged object corresponds to one point counting yoke, one point counting single shaft, one point counting tooth, and one point counting sensor, and the to-be-packaged object is counted once. Since the synchronous feeding device has separated the to-be-packaged objects on each feeding belt with a spacing and is synchronous at the same frequency, it is ensured that each point counting yoke can take away a to-be-packaged object at the same time. The synchronous feeding and the point counting structure are cooperatively arranged to realize the synchronous feeding and counting of the to-be-packaged objects.

DETAILED DESCRIPTION

[0048] The present application will be further described in detail below in combination with all the drawings and specific embodiments.

[0049] The present embodiment is a food counting and feeding packaging machine with seven feeding channels, which can quickly sort and package a specific number of objects to be packaged 9. The objects to be packaged 9 in the present embodiment are circular thin sheet-like fragile foods.

[0050] Reference Figure 1The packaging machine comprises a material arranging device 1, a synchronizing device 2, a counting roller 3, a small carriage 4 and a large carriage 5. The material arranging device 1 is provided with material arranging belts 11. The to-be-packaged materials 9 on each material channel are transported by the material arranging belts 11 so that the to-be-packaged materials 9 are gathered in sufficient quantity in front of the synchronizing device 2, so that the synchronizing device 2 can ensure that there are to-be-packaged materials 9 on each material channel when synchronizing seven material channels each time, and the phenomenon of empty loading of a certain material channel does not occur.

[0051] The to-be-packaged materials 9 continue to move on the material receiving rail 6 after passing through the synchronizing device 2. The other end of the material receiving rail 6 is provided with the counting roller 3. The counting roller 3 connects the to-be-packaged materials 9 on the material receiving rail 6 to the material transferring rail 7 matched with the counting roller 3. With the operation of the counting roller 3, the thin to-be-packaged materials 9 horizontally placed become vertical. The other end of the material transferring rail 7 is provided with a material discharging rail 8. The two sides of the material transferring rail 7 are provided with the small carriages 4 which can move to the material discharging rail 8. The inner side wall of the packaging machine is provided with a large carriage toothed belt 55, a large carriage slide rail, a small carriage toothed belt and a small carriage slide rail 49. The large carriage slide rail is above the small carriage slide rail 49, and the large carriage toothed belt 55 is above the small carriage toothed belt. The large carriages 5 slide in the small carriage slide rail 49 at both ends, and the small carriages 4 slide in the large carriage slide rail at both ends. The large carriages 5 are driven by the large carriage toothed belt 55, and the small carriages 4 are driven by the small carriage toothed belt. The highest point of the counting roller 3 is a first station. When a specific number of to-be-packaged materials 9 are stored in the first station, the small carriages 4 move to pull the to-be-packaged materials 9 and lift the to-be-packaged materials 9 by a distance, so that the to-be-packaged materials 9 are located at a second station on the material transferring rail 7, thereby leaving space for the to-be-packaged materials 9 to be continuously supplied, i.e. emptying the first station. When there are enough to-be-packaged materials 9 in the first station, the large carriages 5 pull the to-be-packaged materials 9 in the second station and the first station to move to a third station on the material discharging rail 8. The material discharging rail 8 discharges the counted to-be-packaged materials 9 transported by the large carriages 5 into a packaging container, thereby completing the packaging.

[0052] With reference to Figure 2 The synchronization function of the synchronizing device 2 is realized by a synchronization toothed belt 24. A bearing plate 26 is fixed along the arrangement direction of the material channels of the to-be-packaged materials 9 on the frame of the packaging machine. One end of the bearing plate 26 is fixedly provided with a synchronization servo motor 21. The output end of the motor is fixedly connected to a transmission wheel 22. The other end of the bearing plate 26 is provided with an adjusting groove 261. The lower end of the adjusting groove 261 is provided with a freely rotatable tensioning wheel 23. The overall frame of the tensioning wheel 23 is fixed at a suitable position of the adjusting groove 261 by an adjusting nut 231.

[0053] On the bearing plate 26 between the synchronous servo motor 21 and the adjusting groove 261, there are also 14 identical support cylinders 27, each of which is provided with a synchronous rotating rod 28, one end of which extends out of the upper part of the support cylinder 27 and is fixedly connected with a synchronous dial 29, and the other end of which extends to the lower part of the bearing plate 26 and is fixedly connected with a synchronous gear 25. The outer circumferential surface of the synchronous dial 29 is provided with four arc-shaped grooves 291. The synchronous gear belt 24 forms a closed loop around the transmission wheel 22 and the tension wheel 23, and is wound in an interlaced manner from the transmission wheel 22 to the tension wheel 23, and then directly returns to the transmission wheel 22 from the tension wheel 23 to form a closed loop, so that the rotating directions of the two adjacent synchronous gears 25 are opposite. After the synchronous servo motor 21 outputs power each time, one arc-shaped groove 291 corresponds to the to-be-packaged object 9, the synchronous dial 29 rotates axially, and one-time synchronous feeding is realized. Thus, the rotating directions of the two adjacent synchronous dials 29 are opposite, the tangential directions of the synchronous dials 29 at the two ends of one material channel are consistent with the movement direction of the to-be-packaged object 9 in the material channel, and the purpose of synchronously dialing the to-be-packaged object 9 is achieved.

[0054] Referring to Figure 1 , after the to-be-packaged object 9 passes through the synchronous dial 29, it reaches the material bearing rail 6, which has two horizontally placed cylindrical circular rails 61 in the middle, and the two circular rails 61 are hollow in the middle to provide space for the movement of the power rod 63 below to drive the to-be-packaged object 9 to move, thereby synchronously conveying the to-be-packaged object 9 to the next process; the outer sides of the two circular rails 61 are vertically erected side plates 62, which are used to limit the running track of the to-be-packaged object 9 and also prevent the to-be-packaged object 9 from falling or separating from the circular rail 61. A power chain is provided below the circular rail 61, and the power chain is provided with a power rod 63. When the power chain rotates, the power rod 63 located between the two circular rails 61 pushes the to-be-packaged object 9 vertically to the movement plane of the to-be-packaged object 9.

[0055] Referring to Figure 3 and Figure 4 , the to-be-packaged object 9 that has passed through the synchronous device 2 is transferred by the counting roller 3 at the end of the material bearing rail 6. The counting roller 3 is coaxially provided with a counting disc 31, and the counting disc 31 rotates synchronously with the rotation of the counting roller 3. The counting disc 31 is provided with a plurality of counting protrusions 311 in the circumferential direction. Each counting single shaft 33 is provided with a counting fork 34 corresponding to the position of each material rotating rail 7. Each counting single shaft 33 corresponds to one counting protrusion 311. The counting single shaft 33 and the counting protrusion 311 are in one-to-one correspondence. A counting sensor 32 is fixedly arranged on the movement track of the counting protrusion 311 on the rack. When each counting protrusion 311 passes through the counting sensor 32, it means that the counting single shaft 33 provides one to-be-packaged object 9 for each material rotating rail 7. The counting sensor 32 counts once, thereby achieving the purpose of counting the amount of feeding.

[0056] The point counting roller 3 is located at the front end of the large carriage 5 and the small carriage 4, and a point counting main shaft 38 is arranged on the packaging machine frame. One point counting disc 37 is fixedly connected to each end of the point counting main shaft 38. A plurality of axial through holes are arranged on each point counting disc 37, and the through holes are arranged in a circumferential array. The through holes on the two point counting discs 37 are one-to-one corresponding, and a point counting single shaft 33 passes through the corresponding through holes arranged oppositely. The point counting single shaft 33 can freely rotate in the through holes. The part of the point counting single shaft 33 inside the two point counting discs 37 is fixedly provided with a point counting fork 34 at a position corresponding to the material supporting rail 6. The point counting fork 34 is provided with a material placing table 341 and a material pushing rod 342. The material pushing rod 342 is U-shaped. The to-be-packaged object 9 on the material supporting rail 6 is pushed to the point counting roller 3 by the power rod 63. The middle part of the U-shaped material pushing rod 342 on the point counting roller 3 is used to accommodate the power rod 63, so as to stably transfer the to-be-packaged object 9 to the point counting roller 3. When the to-be-packaged object 9 is transferred from the material supporting rail 6 to the point counting fork 34, the to-be-packaged object 9 is supported and connected by the material pushing rod 342 and abuts against the material placing table. One end of the point counting main shaft 38 is provided with a gear-shaped disc. The gear-shaped disc rotates synchronously with the point counting main shaft 38. Each tooth of the gear-shaped disc is a point counting convex tooth 311. The position and number of the point counting convex teeth 311 correspond to the point counting single shaft 33 one-to-one. A point counting sensor 32 is arranged on the packaging machine frame at a position corresponding to the movement track of the point counting convex tooth 311, so as to count the number of to-be-packaged objects supplied by the point counting single shaft 33.

[0057] Since the point counting roller 3 rotates in a circumferential direction, the transfer rail 7 upstream and downstream of the point counting roller 3 is straight, and the transfer rail 7 in the circumferential direction of the transfer of the point counting roller 3 is in an arc shape. The transfer rail 7 includes two material supporting pieces 71 and two limiting pieces 72. The to-be-packaged object 9 is placed on the two material supporting pieces 71. The two limiting pieces 72 are erected on both sides of the to-be-packaged object 9, so as to limit the position of the to-be-packaged object 9, so that the to-be-packaged object 9 will not fall off the production line. With the rotation of the point counting roller 3, the sheet-shaped to-be-packaged object 9 gradually stands up. At this time, the included angle between the point counting fork 34 and the advancing direction of the transfer rail 7 is smaller and smaller, and there is a possibility that the point counting fork 34 will crush the fragile to-be-packaged object 9. In order to prevent the point counting fork 34 from crushing the to-be-packaged object 9 at a higher position of the transfer rail 7, the point counting roller 3 has the following structure.

[0058] Referring to Figure 5 and Figure 6, the control fork fixed disc 35 is provided with a control fork fixed disc 35, and the control fork fixed disc 35 penetrates the total number of shafts 38 and is not linked with the total number of shafts 38. The end of the number single shaft 33 is fixedly connected with the control fork rotating rod 36, and the other end of the control fork rotating rod 36 is provided with the control fork sliding block 361 away from the number rotating disc 37. The control fork sliding block 361 slides in the control fork sliding groove 351 of the control fork fixed disc 35, and the control fork sliding groove 351 is irregularly annular. The irregular annular shape can ensure the rotation of the number single shaft 33. The distance of the control fork sliding groove 351 from the center of the control fork fixed disc 35 changes from large to small, and the rotation direction of the control fork single shaft is opposite to the revolution direction of the number single shaft 33 around the total number of shafts 38; the distance of the control fork sliding groove 351 from the center of the control fork fixed disc 35 changes from small to large, and the rotation direction of the control fork single shaft is the same as the revolution direction of the number single shaft 33 around the total number of shafts 38. Referring to Figure 7 and Figure 8 , the control fork sliding groove 351 on the control fork fixed disc 35 is irregularly annular. In the arc of the control fork sliding groove 351 towards the material rotating rail 7, the position of the control fork sliding groove 351 is closer to the center of the control fork fixed disc 35. The control fork sliding groove 351 corresponding to the angles α, β and γ in the figure is the process stage when the number fork 34 moves to contact the material rotating rail 7 and then separates from the material rotating rail 7. In the α section, the pushing rod 342 of the number fork 34 gradually deviates to the left in the figure, and the pushing rod 342 keeps pushing the to-be-packaged object 9, so that the to-be-packaged object 9 does not lose the pushing force and fall or slide. The inclined surface of the pushing rod 342 keeps a position substantially perpendicular to the position of the material rotating rail 7; in the β section, the pushing rod 342 of the number fork 34 is about to separate from the to-be-packaged object 9, and the pushing rod 342 of the number fork 34 rotates at a large angle, so as to return to the normal regular operation angle in a smaller rotating stroke; in the γ section, the number fork 34 is about to adjust the angle and contact the to-be-packaged object 9 on the material rail 6 in the horizontal position, and the position of the control fork sliding groove 351 from the center of the control fork fixed disc 35 is larger and larger.

[0059] Figure 8 In the α section, the number roller 3 rotates clockwise, the distance of the control fork sliding groove 351 from the center of the control fork fixed disc 35 changes from large to small, and the pushing rod 342 rotates counterclockwise; in the γ section, the distance of the control fork sliding groove 351 from the center of the control fork fixed disc 35 changes from small to large, and the pushing rod 342 rotates clockwise.

[0060] The number disc 31 is arranged outside the control fork fixed disc 35 away from the number rotating disc 37. The maximum distance of the control fork sliding groove 351 to the control fork fixed disc 35 is the same as the distance of the number single shaft 33 to the total number of shafts 38. The control fork fixed disc 35 is closer to the number rotating disc 37, which is convenient for controlling the rotation of the number single shaft 33, so that the distance of the control fork sliding groove 351 to the center of the control fork fixed disc 35 changes smaller, and the required rotation angle of the number single shaft 33 can be realized.

[0061] Referring toFigures 3-8 The working process of the point counting roller 3 is as follows: the point counting main shaft 38 rotates to drive the point counting turntable 37 to rotate, the point counting turntable 37 drives the point counting single shaft 33 to rotate around the point counting main shaft 38, the point counting single shaft 33 drives the point counting fork 34 on the point counting single shaft 33 to move along the axial direction of the point counting main shaft 38, so that the to-be-packaged object 9 is transferred from the horizontal material supporting rail 6 to the point counting fork 34, the point counting fork 34 supports the to-be-packaged object 9, the pushing rod 342 pushes the to-be-packaged object 9 to move forward, and the limiting member 72 on the two sides of the material rotating rail 7 limits the position of the to-be-packaged object 9, so that the to-be-packaged object 9 will not fall off. When the point counting fork 34 and the straight part of the material rotating rail 7 are about to be perpendicular, the control fork sliding block 361 fixed outside the point counting single shaft 33 will make the point counting single shaft 33 rotate counterclockwise along the axis of the point counting single shaft 33, Figure 8 The inclination angle of each pushing rod 342 in the packaging machine can also be seen to have such a movement tendency. When moving to the β section, the next to-be-packaged object 9 will be in contact with the to-be-packaged object 9, and the to-be-packaged object 9 will not lose power and slide or fall down because of being separated from the pushing rod 342. At this time, the pushing rod 342 is separated from the to-be-packaged object 9, and the position of the control fork sliding groove 351 makes the point counting single shaft 33 rotate clockwise along the axis of the point counting single shaft 33.

[0062] Referring to Figure 9 and Figure 10 The small carriage 4 is arranged in the next working process of the point counting roller 3. When the first working position of the material rotating rail 7 collects a specific number of sheet to-be-packaged objects 9, the small carriage 4 pulls the to-be-packaged objects 9 to the second working position at the far end of the material rotating rail 7, so as to empty the first working position to prepare space for the to-be-packaged objects 9 to be collected.

[0063] The inner side wall of the packaging machine rack is provided with a trolley sliding rail 49, the small carriage 4 is provided with a trolley frame 41, one end of the trolley frame 41 is provided with a trolley sliding block 45, and the other end is provided with a trolley walking block 46. The trolley sliding block 45 is in sliding connection with the trolley sliding rail 49, the trolley walking block 46 is fixed with a trolley toothed belt, the trolley toothed belt is driven to move the small carriage 4 as a whole along the direction of the material rotating rail 7, so as to realize the movement of the small carriage 4 between the first working position and the second working position.

[0064] The trolley walking block 46 is fixed with a lifting servo motor 42, the output shaft of the lifting servo motor 42 transmits power to a transmission gear 43, the center of the transmission gear 43 is fixed with a threaded rod 44, the threaded rod 44 is in threaded connection with a threaded block 441, the threaded block 441 is provided with a U-shaped structure, a pushing block 442 is arranged in the middle of the U-shaped structure, and the pushing block 442 is connected with a trolley pushing shaft 47. The transmission gear 43 is driven to move the threaded block 441 up and down along the threaded rod 44, the U-shaped structure of the threaded block 441 pushes the pushing block 442 to make the trolley pushing shaft 47 connected with the pushing block 442 rotate back and forth along the axis of the trolley pushing shaft 47 in the direction of B-B1. The small carriage 4 moves linearly in the direction of A-A1 in the rack of the packaging machine.

[0069] The large vehicle 5 as a whole realizes linear reciprocating movement along the C-C1 direction under the transmission of the large vehicle toothed belt 55.

[0070] Referring to Figure 15 When the counting of the counting roller 3 is completed and the specific to-be-packaged objects 9 are gathered at Figure 15 the position, at this time, the to-be-packaged objects 9 are located at the first station, the small vehicle 4 moves to the B1 direction, pulls the to-be-packaged objects 9, and pulls them to the far end of the material rotating rail 7, the E position before the material rotating rail 7 is the material rotating rail 7, and the E position after the material rotating rail 7 is the material discharging rail 8. The small vehicle 4 pulls the to-be-packaged objects 9 to the rear end of the material rotating rail 7, and temporarily stores the to-be-packaged objects 9 at the front end of the E position.

[0071] Referring to Figures 15-18 The initial position of the large vehicle 5 is that the front fork 511 of the large vehicle 5 is located above the first station. The front fork 511 is a straight plate-shaped long strip structure. When the small vehicle 4 pulls the to-be-packaged objects 9 to the rear end of the material rotating rail 7, the to-be-packaged objects 9 at this time are located at the second station, and the initial position of the small vehicle 4, that is, the first station, has stored the same number of to-be-packaged objects 9. The large vehicle 5 first lowers the rear fork 521 to receive the to-be-packaged objects 9 from the U-shaped hook 481 of the small vehicle 4, that is, the large vehicle 5 lowers the rear fork 521 at the second station. The large vehicle 5 lowers the front fork 511, that is, the large vehicle 5 lowers the front fork 511 at the first station. The front fork 511 limits the same number of to-be-packaged objects 9 at the first station. At the same time when the front fork 511 of the large vehicle 5 is limited, the small vehicle 4 moves on the material rotating rail 7 to the direction of the counting roller 3 to return to the initial position, that is, the first station, to prepare for the next pulling of the to-be-packaged objects 9.

[0072] Referring to Figure 19, the first and second workstations of the to-be-packaged objects 9 are positioned on the discharging rail 8, and the final position of the large vehicle 5 is the third workstation. The discharging rail 8 and the material transferring rail 7 both support the to-be-packaged objects 9 by two supporting objects 71. The difference is that the distance between the two supporting objects 71 of the material transferring rail 7 cannot be changed, while the distance between the two supporting objects 71 of the discharging rail 8 can be changed, and the to-be-packaged objects 9 are discharged into the packaging container or packaging bag to complete the packaging by changing the distance between the two supporting objects 71 of the discharging rail 8.

[0073] The implementation principle of the embodiment is that the counting device and the feeding device are realized in one set of equipment, and the combination of the counting device and the feeding device is simplified. The counting roller 3 counts the to-be-packaged objects 9, and the counting roller 3 is provided with counting single shafts 33 in the axial direction, each counting single shaft 33 corresponds to a counting tooth, and each counting shaft is provided with a counting yoke 34, and each counting yoke 34 drives a to-be-packaged object 9. Therefore, one to-be-packaged object 9 corresponds to one counting yoke 34, one counting single shaft 33, one counting tooth, and one counting sensor 32, and the counting sensor 32 will count once. Since the synchronous feeding device has separated the to-be-packaged objects 9 of each feeding belt with a certain distance and is synchronous at the same frequency, it is ensured that each counting yoke 34 can take away a to-be-packaged object 9 at the same time. The synchronous feeding and counting structure are set in cooperation to realize the synchronous feeding and counting packaging of the to-be-packaged objects 9.

[0074] The counting yoke 34 gradually separates from the to-be-packaged object 9, a yoke fixing disc 35 is arranged, the rotation movement of the counting single shaft 33 along its own axis is controlled, the counting single shaft 33 rotates around the counting main shaft 38 while rotating around its own axis, the sharp end of the U-shaped pushing rod 342 moves away from the to-be-packaged object 9, so that the counting yoke 34 does not continuously apply force to the to-be-packaged object 9 by the sharp end of the U-shaped pushing rod 342, and therefore the pushing rod 342 does not crush the to-be-packaged object 9.

[0075] When the to-be-packaged object 9 is driven, the driving is stable and there is no large amplitude vibration, the feeding is synchronous with the counting, the to-be-packaged object 9 does not need to be separately taken through another process, the rolling type counting roller 3 is used to realize rolling type continuous feeding, the to-be-packaged objects 9 are arranged in order, and become high-grade packaging products of a specific number without fragmentation.

[0076] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
