Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging machines, in particular to a synchronous feeding and counting packaging machine. BACKGROUND

[0002] Food packaging machines are machines that package edible products, which protect and beautify the food products.

[0003] When the food production is large, multiple production lines are needed to achieve efficient production. A counting device is provided in front of each production line to flow a specific number of products into the production line to achieve packaging. The specific number of products conveyed by each production line is packaged in one package. In existing packaging machines for fragile piece-shaped food, the multiple conveying belts of the multiple production lines are independently controlled and adjusted at different conveying speeds. Because the efficient packaging and sealing process can package multiple products at a time, the packaging machine needs to position the products from multiple production lines at a specific location before packaging and sealing.

[0004] In the above related technology, the multiple conveying belts are independently controlled and move independently, which makes it difficult to achieve precise synchronous feeding of the multiple conveying belts. The feeding frequency and cycle of each conveying belt are different, which makes the final sealing and packaging unsatisfactory. The feeding of one production line has been completed and is ready for packaging, while the feeding of other production lines has not yet been transferred to the packaging position. Therefore, the terminal sealing station is forced to extend the cycle, which not only reduces the production efficiency, but also cannot completely avoid empty packaging or different packaging quantities of different conveying belts, and it is also difficult to achieve standard and unified packaging production and management. SUMMARY

[0005] To achieve synchronous feeding of multiple conveying belts of a food packaging machine, the present application provides a synchronous feeding and counting packaging machine, which adopts the following technical solution.

The synchronous servo motor drives the synchronous gear to rotate by a certain angle through the synchronous toothed belt, and correspondingly, the synchronous dialing wheel of the to-be-packaged objects on the material conveying belt also rotates by the same angle, so as to realize the synchronous feeding of the material conveying belts.

[0010] The synchronous gear arranged on the same side of the material conveying belt corresponding to the dialing assembly is arranged in the same direction with the synchronous toothed belt, and the synchronous gear arranged on the different side of the material conveying belt corresponding to the dialing assembly is arranged in the reverse direction with the synchronous toothed belt.

[0011] By adopting the above technical scheme, each material channel, that is, each material conveying belt can be provided with one dialing assembly or two dialing assemblies, and the synchronous gears of all the dialing assemblies are arranged in the same plane. The servo motor drives the power out through the synchronous rack and then through the synchronous gear.

[0012] Preferably, each material conveying belt is provided with a set of the dialing assembly, the synchronous gears are arranged in sequence, and the synchronous toothed belt is arranged in the same direction on the synchronous gears.

[0013] By adopting the above technical scheme, the middle or the same side of each material conveying guide rail is provided with a set of dialing assembly, and one set of dialing assembly can meet the passing of the to-be-packaged objects. At this time, the transmission is the ring-shaped closed synchronous toothed belt in the tooth direction, and the ring-shaped interior is engaged with the synchronous gears. All the synchronous gears are ensured to rotate in the same direction at the same time, so as to dial the to-be-packaged objects and realize the synchronous feeding.

[0014] Preferably, each material conveying belt is provided with two sets of the dialing assembly, the two sets of the dialing assembly are arranged on the two sides of the corresponding material conveying belt respectively, the synchronous gears are arranged in sequence, and the synchronous toothed belt is arranged on the synchronous gears in the alternating direction.

[0015] By adopting the technical scheme, each of the two sides of each conveying belt is provided with a set of poking assembly, the poking assemblies on the two sides of each conveying belt rotate in opposite directions, and the two sides of the to-be-packaged objects on each conveying belt are simultaneously allowed to move in the movement direction of the conveying belt.

[0016] Preferably, the rack is further provided with a tensioning wheel, the tensioning wheel is in the same plane as the synchronous gear, and the tensioning wheel can freely rotate around its own axis.

[0017] By adopting the technical scheme, the tensioning wheel is placed at the end of the bearing plate, the synchronous gear is balanced in force, the synchronous gear belt does not generate excessive tension on the synchronous gear, the transmission of the synchronous gear is not affected, or the service life of the synchronous gear is reduced.

[0018] Preferably, the rack is further provided with an adjusting groove, and the distance between the tensioning wheel and the synchronous gear is adjusted by changing the positional relationship between the tensioning wheel and the adjusting groove.

[0019] By adopting the technical scheme, under the condition that the packaging machine is operated for a long time, the synchronous gear belt may be fatigued or relaxed, the transmission may be affected, and in this case, the position of the tensioning wheel on the bearing plate is adjusted to tension the belt again, thereby ensuring the transmission.

[0020] Preferably, the outer circumferential surface of the synchronous poking wheel is provided with four arc-shaped grooves.

[0021] By adopting the technical scheme, after each output of power by the synchronous servo motor, there is an arc-shaped groove corresponding to the to-be-packaged object, the synchronous poking wheel rotates axially, and one-time synchronous conveying is realized.

[0022] In summary, the present application has at least one of the following beneficial technical effects.

[0023] 1. The servo motor outputs power, the power is transmitted to the poking assembly through the synchronous gear belt, each conveying belt is provided with a poking assembly on both sides, the lower part of the poking assembly is provided with a synchronous gear, each synchronous gear is connected with the synchronous gear belt, and each conveying belt is connected with the synchronous gear belt. Therefore, the poking assemblies of the various channels can move synchronously.

[0024] 2. Each set of poking assemblies is fixed on the rack, and a bearing plate is fixed on the rack. The bearing plate is used for installing the poking assembly, the poking assembly is fixedly installed on the bearing plate of the rack, all the synchronous gears are on one side of the bearing plate, and all the synchronous gears are connected with the synchronous gear belt. The to-be-packaged objects on all the conveying belts will be allowed to pass at the same time.

[0025] 3. Each material channel, i.e. each material conveying belt, can be provided with one or two material pushing assemblies, and the synchronization gears of all the material pushing assemblies are in the same plane. The servo motor transmits power through the synchronization rack and then through the synchronization gears. Since it is the same synchronization rack, the movement of the synchronization gears is synchronized, i.e. the movement of the material pushing assemblies is synchronized, thereby realizing synchronized feeding, improving work efficiency, and quickly completing packaging.

[0026] 4. After synchronized feeding, the counting roller counts the to-be-packaged objects. The counting roller is provided with counting single shafts in the axial direction, each counting single shaft corresponding to a counting tooth, and each counting shaft is provided with a counting yoke, each counting yoke driving a to-be-packaged object. Therefore, one to-be-packaged object corresponds to one counting yoke, one counting single shaft, one counting tooth, and one counting sensor, which will count once. Since the synchronized feeding device has separated the to-be-packaged objects of each material conveying belt with a distance and at the same frequency, it ensures that each counting yoke can take away a to-be-packaged object at the same time. The synchronized feeding and counting structure realize synchronized feeding and counting packaging of the to-be-packaged objects. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

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

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

[0050] Referring to Figure 1 , the packaging machine comprises a sorting device 1, a synchronization device 2, a counting drum 3, a small carriage 4, and a large carriage 5. The sorting device 1 is provided with sorting belts 11. The to-be-packaged objects 9 on each feeding channel are transported by the multiple sorting belts 11, so that the to-be-packaged objects 9 are gathered in a sufficient number at the front end of the synchronization device 2, so that the synchronization device 2 can ensure that there are to-be-packaged objects 9 on each feeding channel when synchronizing the seven feeding channels, and the phenomenon of empty loading of a certain feeding channel does not occur.

[0051] The to-be-packaged objects 9 continue to move on the material receiving rail 6 through the synchronizing device 2, and the other end of the material receiving rail 6 is provided with a counting roller 3, which receives the to-be-packaged objects 9 from the material receiving rail 6 to a material transferring rail 7 matched with the counting roller 3, and the horizontally placed sheet-shaped to-be-packaged objects 9 become vertical with the operation of the counting roller 3. The other end of the material transferring rail 7 is provided with a material discharging rail 8, and the two sides of the material transferring rail 7 are provided with small trolleys 4 that can move to the material discharging rail 8, and the inner side wall of the packaging machine is provided with a large trolley toothed belt 55, a large trolley slide rail, a small trolley toothed belt and a small trolley slide rail 49, the large trolley slide rail is above the small trolley slide rail 49, and the large trolley toothed belt 55 is above the small trolley toothed belt. The two ends of the large trolley 5 slide in the small trolley slide rail 49, and the two ends of the small trolley 4 slide in the large trolley slide rail. The large trolley 5 is driven by the large trolley toothed belt 55, and the small trolley 4 is driven by the small trolley toothed belt. The highest point of the counting roller 3 is a first station, when a certain number of to-be-packaged objects 9 are stored in the first station, the small trolley 4 moves to pull these to-be-packaged objects 9, and lifts the to-be-packaged objects 9 by a distance, so that the to-be-packaged objects 9 are located at a second station on the material transferring rail 7, and the to-be-packaged objects 9 behind continue to be supplied to the first station, that is, the first station is emptied. When there are enough to-be-packaged objects 9 in the first station, the large trolley 5 pulls the to-be-packaged objects 9 in the second station and the first station, and moves them together to a third station on the material discharging rail 8, and the material discharging rail 8 discharges the to-be-packaged objects 9 transported by the large trolley 5 to the packaging container, and completes the packaging.

[0052] Referring 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 on the frame of the packaging machine along the direction of the to-be-packaged object 9 channel, 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 with a transmission wheel 22, the other end of the bearing plate 26 is provided with an adjusting groove 261, and the lower end of the adjusting groove 261 is provided with a freely rotating tension wheel 23, and the overall frame of the tension wheel 23 is fixed at a suitable position of the adjusting groove 261 through 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.

[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 is before the material rotating rail 7, and the E position is after the material placing 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 them 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 that 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 time of pulling the to-be-packaged objects 9.

[0072] Referring to Figure 19The first and second workstations of the large vehicle 5 are moved away from the counting roller 3 until they are positioned above the discharge rail 8 at the position E, and the large vehicle 5 is finally positioned at the third workstation. The discharge rail 8 is similar to the transfer rail 7 in that it supports the objects 9 to be packaged by two supporting members 71. The difference is that the distance between the two supporting members 71 of the transfer rail 7 cannot be changed, while the distance between the two supporting members 71 of the discharge rail 8 can be changed. The objects 9 to be packaged are discharged by changing the distance between the two supporting members 71 of the discharge rail 8 and then placed into a packaging container or a packaging bag to complete the packaging.

[0073] The principle of the embodiment is that the servo motor outputs power, which is transmitted to the poking assembly through the synchronous toothed belt 24. Each conveying belt is provided with a poking assembly on both sides. The lower part of the poking assembly is provided with a synchronous gear 25. Each synchronous gear 25 is connected with the synchronous toothed belt 24. Each synchronous gear 25 of each conveying belt is connected with the synchronous toothed belt 24. Therefore, the poking assemblies of each channel can move synchronously. Each set of poking assemblies is fixed on the rack. The rack is fixedly provided with a bearing plate 26. The bearing plate 26 is used for mounting the poking assembly. The poking assembly is fixedly mounted on the bearing plate 26 of the rack. All the synchronous gears 25 are on one side of the bearing plate 26. All the synchronous gears 25 are connected with the synchronous toothed belt 24. All the objects 9 on the conveying belts will be allowed to pass at the same time. Each channel, i.e., each conveying belt, can be provided with one poking assembly or two poking assemblies. The synchronous gears 25 of all the poking assemblies are in the same plane. The servo motor transmits power through the synchronous rack and then through the synchronous gears 25. Since it is the same synchronous toothed belt 24, the movements of the synchronous gears 25 are synchronous, that is, the movements of the poking assemblies are synchronous, thereby realizing synchronous feeding, improving work efficiency, and quickly completing packaging.

[0074] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered by the protection scope of the present application.
