Description

Technical Field

[0001] The present invention belongs to the technical field of equidistant arrangement in the canned food conveying link, and particularly relates to a canned food arranging and conveying device, a lid closing system and a method. Background Art

[0002] During the production process of canned food, it is usually conveyed densely along the conveying trough, that is, adjacent canned foods are in contact with each other, which will lead to the inability to effectively control the conveying rhythm and the inconvenience of accurately positioning the canned foods in some production links. For example, the densely conveyed canned foods also cause difficulties for the vacuum suction cup or transfer fixture to accurately position the canned foods during subsequent packaging; or it is difficult to accurately position when placing the canned food cover on the top of the canned food. Therefore, it is necessary to study how to arrange the densely conveyed canned foods so that the canned foods are conveyed in an equidistant arrangement, and how to improve the positioning accuracy of the canned foods in multiple production links. Summary of the Invention

[0003] To solve the deficiencies of the prior art, the present invention provides a canned food arranging and conveying device, a lid closing system and a method, which can convey the canned foods in an equidistant arrangement and meet the requirements for positioning accuracy during the conveying process.

[0004] In order to achieve the purpose of the present invention, the following scheme is proposed: A canned food arranging and conveying device includes: a support plate, a sliding frame and side clamping plates.

[0005] The support plate is arranged parallel and at intervals above the conveying trough for conveying canned foods; The sliding frame is arranged parallel above the support plate, and a driving element is provided at the front end of the support plate for driving the sliding frame to reciprocate in the front-rear direction of the support plate; There are two side clamping plates, which are respectively arranged parallel on both sides at the same height below the support plate and above the conveying trough. The two side clamping plates are parallel to each other, and a plurality of pairs of arranged clamping grooves are arrayed on the opposite sides; The outer sides of the side clamping plates are connected to the outer sides of the sliding frame through support ears, and the side clamping plates are arranged to move along the width direction of the sliding frame. Clamping springs are provided on both sides of the sliding frame for applying pressure to the side clamping plates towards the middle of the sliding frame; A set of guiding components are provided on both sides of the bottom surface of the support plate for guiding the side clamping plates to move along the width direction of the sliding frame; when the sliding frame moves to a predetermined position at the front end of the support plate, the two side clamping plates move towards the middle of the sliding frame simultaneously for clamping the canned foods; when the sliding frame moves a predetermined distance towards the rear end of the support plate, the two side clamping plates move towards the outer sides of the sliding frame simultaneously for releasing the canned foods, and the predetermined distance is the same as the distance between adjacent clamping grooves on the side clamping plates; A baffle is arranged through the input end of the conveying trough corresponding to the lower part of the support plate, and the baffle is arranged to move along the direction perpendicular to the extension of the conveying trough.

[0006] A can lid closing system includes the above-mentioned can arranging and conveying device. In the middle of the top surface of the support plate, a storage barrel for stacking can lids is vertically provided. A through hole is vertically opened at the front end of the support plate. The outer circumferential surface of the can lid is in close contact with the inner wall of the through hole. The storage barrel and the through hole are on the same front-rear connection line of the support plate and are located directly above the conveying groove. A push plate facing the front end is provided at the rear end of the sliding frame. The thickness of the push plate is less than or equal to the thickness of the can lid. A through hole for passing through the push plate is opened at the bottom of the storage barrel along the front-rear connection line direction of the support plate. The height of the through hole is greater than the thickness of one can lid and less than the thickness of two can lids. When the sliding frame moves to a predetermined position at the front end of the support plate, the push plate pushes the can lid at the bottom of the storage barrel above the through hole. A rotating plate is hinged to the top of the front end of the support plate. A pressing plate is provided at the bottom of the end of the rotating plate. An elastic member is provided between the bottom of the rotating plate and the support plate. When it is in the natural state, the end of the rotating plate is inclined upward toward the rear end of the support plate, and the interval between the bottom of the pressing plate and the top surface of the through hole is greater than the thickness of the can lid. During the process of the sliding frame moving toward the rear end of the support plate, the front frame of the sliding frame pushes the rotating plate to swing downward, and presses the can lid above the through hole into the through hole through the pressing plate. When the sliding frame moves a predetermined distance toward the rear end of the support plate and the two side clamping plates release the can and continue to move backward, during the process of the sliding frame continuing to move backward, the pressing plate pushes the can lid in the through hole downward out of the through hole and presses it onto the top of the can.

[0007] A can lid closing method is realized by using the above-mentioned can lid closing system. The method includes the following steps: S1: Pushing the can lid. Using the driving element to push the sliding frame forward, and pushing the can lid at the bottom of the storage barrel above the through hole through the push plate. S2: Clamping and positioning. The sliding frame moves forward to a predetermined position at the front end of the support plate. The two side clamping plates synchronously close toward the middle, clamp the can against which the baffle is held through the first card slot at the front end, and clamp the cans arranged behind in the conveying groove through the remaining card slots of the side clamping plates. The baffle moves out from the inside of the conveying groove. S3: Pushing the can. Using the driving element to push the sliding frame backward, so that the sliding frame moves to a predetermined position at the rear end of the support plate. The baffle is inserted into the conveying groove again to hold the cans behind. The two side clamping plates move to both sides at the same time to release the can. The released can is coaxially located below the through hole. The pressing plate presses the can lid above the through hole into the through hole. S4: Closing the lid. Using the driving element to continue pushing the sliding frame backward, using the front frame of the sliding frame to continue pushing the rotating plate to rotate downward, and using the pressing plate to press the can lid in the through hole onto the top of the can.

[0008] The beneficial effects of the present invention are as follows: 1. Canned foods can be arranged at equal intervals on the conveying trough by using side clamping plates, so as to achieve the purpose of conveying canned foods at equal intervals within the length range of the side clamping plates. During the production process of canned foods, the positioning process that requires accurate positioning can be set within the moving range of the side clamping plates to ensure the accuracy of the positions of the canned foods on the conveying trough during processing.

[0009] 2. Incorporating the lid closing process into the arranging and conveying device, the driving element of the arranging and conveying device can be used to synchronously complete the lid closing process, which can not only ensure the relative position accuracy between the can lid and the can during lid closing, but also effectively reduce the setting of power elements and avoid designing a complex control system.

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will describe the embodiments of the present invention in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Embodiment 1, as Figure 1 , Figure 2 shown, a can arranging and conveying device includes: a support plate 1, a sliding frame 2, and a side clamping plate 3.

[0030] The support plate 1 is disposed parallel and at intervals above the conveyor trough 4 for conveying cans, and the direction of the line connecting the front and rear ends of the support plate 1 is parallel to the conveying direction of the conveyor trough 4.

[0031] The sliding frame 2 is disposed parallel to the upper side of the support plate 1. A driving element 11 is provided at the front end of the support plate 1 for driving the sliding frame 2 to reciprocate in the front-rear direction along the support plate 1. In this application, the description of the front and rear directions is defined based on the direction of the support plate 1.

[0032] There are two side clamping plates 3, which are respectively disposed parallel to both sides at the same height below the support plate 1 and are located above the conveying groove 4. The two side clamping plates 3 are parallel to each other, and a plurality of pairs of clamping grooves 301 are arranged in an array on the opposite sides for clamping cans. To ensure the positioning accuracy during clamping and to accommodate cans of different outer diameters, the clamping grooves 301 are set as a V-shaped structure or a semi-circular structure.

[0033] The outer sides of the side clamping plates 3 are connected to the outer sides of the sliding frame 2 through support ears 31. To ensure the stability of the connection structure, usually two or more support ears 31 are provided, and the side clamping plates 3 are movably arranged along the width direction of the sliding frame 2. Specifically, a rod body can be provided on the side of the support ear 31 facing the sliding frame 2, and the rod body passes through the side surface of the sliding frame 2 to connect the support ear 31 to the sliding frame 2 and meet the requirement for the side clamping plate 3 to move along the width direction of the sliding frame 2; or guide rails can be provided on both sides of the sliding frame 2. The cross-section of the guide rails can be set as a T-shaped structure or a polygonal structure, and the upper ends of the support ears 31 are slidably connected to the guide rails, or the guide rails pass through the support ears 31. Clamping springs 21 are provided on both sides of the sliding frame 2 for applying a pressure towards the middle of the sliding frame 2 to the side clamping plates 3. Specifically, the two ends of the clamping springs 21 can be respectively connected to the support ears 31 and the sliding frame 2. By using the elastic force generated when the clamping springs 21 contract, the side clamping plates 3 are driven to move towards the middle, so that the cans are fixed by the elastic force generated by the clamping springs 21 through the paired clamping grooves 301 on the side clamping plates 3.

[0034] A set of guiding components 12 are provided on both sides of the bottom surface of the support plate 1. When the sliding frame 2 moves to a predetermined position on the support plate 1, the guiding components 12 are used to guide the side clamping plates 3 to move along the width direction of the sliding frame 2.

[0035] Combined with Figures 1 to 4 As shown, when the sliding frame 2 moves to a predetermined position at the front end of the support plate 1, the two side clamping plates 3 move towards the middle of the sliding frame 2 simultaneously for clamping the cans.

[0036] Combined with Figures 6 to 8 As shown, when the sliding frame 2 moves a predetermined distance towards the rear end of the support plate 1, the two side clamping plates 3 move towards the outside of the sliding frame 2 simultaneously for releasing the cans. The predetermined distance is the same as the distance between adjacent clamping grooves 301 on the side clamping plates 3.

[0037] Combined with as Figure 2 、 Figure 7 、 Figure 11As shown, a baffle 41 is provided through the lower part corresponding to the input end of the conveying trough 4, and the baffle 41 is movably arranged along the direction perpendicular to the extension of the conveying trough 4.

[0038] Through the above design, during the can conveying process, as Figure 7 , Figure 8 shown, when the can is conveyed to the baffle 41, it will be blocked by the baffle 41 to prevent the can from moving backward. The sliding frame 2 is moved to a predetermined position at the front end of the support plate 1 by the driving element 11. As Figure 3 , Figure 4 shown, at this time, the two side clamping plates 3 move towards the middle of the sliding frame 2 at the same time, and the can in contact with the baffle 41 is clamped by the first pair of card slots 301 provided at the front end of the side clamping plate 3. Then, the driving element 11 is used to move the sliding frame 2 backward to drive the clamped can to move backward in the conveying trough 4, and at the same time, the baffle 41 is removed from the conveying trough 4, so that the clamped can passes smoothly. And after the clamped can passes, the baffle 41 is inserted into the conveying trough 4 again to block the next can. Combining Figure 8 , Figure 12 shown, when the sliding frame 2 moves to a predetermined position at the rear end of the support plate 1, the two side clamping plates 3 move towards the outside of the sliding frame 2 at the same time, so as to achieve the purpose of releasing the clamped can. The moving distance of the sliding frame 2 between the two positions of clamping and releasing the can is the same as the distance between the card slots 301 on the side clamping plate 3. After the can is released, the driving element 11 drives the sliding frame 2 to move forward, so that the sliding frame 2 moves to a predetermined position at the front end of the support plate 1 again. At this time, the first card slot 301 in front of the side clamping plate 3 clamps and resists the can behind the baffle 41, and the second card slot 301 in front clamps the can that was released before and is in front of the baffle 41, and drives the two clamped cans to move towards the rear end of the conveying trough 4 under the drive of the sliding frame 2. And when the sliding frame 2 moves backward a predetermined distance, the clamped can will be released again. By repeating the above process multiple times, the cans can be arranged at equal intervals on the conveying trough 4 by using the side clamping plates 3, so as to achieve the purpose of conveying the cans at equal intervals within the length range of the side clamping plates 3. During the can production process, the processing procedures that require accurate positioning can be set within the moving range of the side clamping plates 3. Specifically, the devices or tools involved in the processing procedures that require accurate positioning can be installed on the support plate 1. To ensure that there is enough space within the moving range of the side clamping plates 3 to set the devices and tools for various procedures, the length of the side clamping plates 3 can be extended according to actual needs, and the number of card slots 301 opened on the side clamping plates 3 can be increased; In this embodiment, the conveying trough 4 behind the baffle 41 does not actively drive the cans to move. Instead, the cans that move to the conveying trough 4 behind the baffle 41 only move under the drive of the side clamping plates 3. The can bodies in front of the baffle 41 on the conveying trough 4 are sent into the conveying trough 4 through the belt transmission device provided at the front end of the conveying trough 4. The cans that have completed the predetermined process within the moving range of the side clamping plates 3 can also be pushed further towards the rear end of the conveying trough 4 under the pushing action of the side clamping plates 3.

[0039] Preferably, as shown in Figure 4 , Figure 8 and Figure 12 , a limiting member 32 is provided on the top surface of the side clamping plate 3. The guiding assembly 12 includes a parallel bar 121 parallel to the connection line between the front and rear ends of the support plate 1. An inclined bar 122 is provided at an interval behind it. The interval size is larger than the outer contour size of the limiting member 32 to facilitate the smooth passing of the limiting member 32 between the parallel bar 121 and the inclined bar 122. The front end of the inclined bar 122 is inclined towards the middle of the front of the support plate 1. Therefore, the rear end of the inclined bar 122 will face the outside of the rear of the support plate 1. And the distance between the front end of the inclined bar 122 and the center line of the support plate 1 is smaller than the distance between the parallel bar 121 and the center line of the support plate 1. The distance between the front end of the parallel bar 121 and the inclined bar 122 is equal to the spacing between adjacent card slots 301 on the side clamping plate 3.

[0040] At the end of the parallel strip 121, a stop strip 123 is rotatably provided, and a torsion spring is provided at the rotation point. When the torsion spring is in its natural state, the end of the stop strip 123 supports on the surface of the inclined strip 122 facing the parallel strip 121, and the outer side surface of the stop strip 123 is in the same plane as the outer side surface of the parallel strip 121. When the limiting member 32 contacts the outer side surfaces of the parallel strip 121 and the stop strip 123, the distance between the two side clamping plates 3 is the largest. When the side clamping plates 3 clamp the can, the limiting member 32 is located inside the parallel strip 121 and the stop strip 123. Therefore, the can between the two side clamping plates 3 is in a released state at this time. During operation, the stop strip 123 swings outward under the pushing action of the limiting member 32, and after separating from the limiting member 32, it automatically swings inward under the action of the torsion spring restoring its elastic deformation, so that the end of the stop strip 123 abuts against the surface of the inclined strip 122 facing the parallel strip 121 again to prevent the stop strip 123 from swinging inward continuously. When the sliding frame 2 moves to a predetermined position at the front end of the support plate 1, the limiting member 32 moves in front of the parallel strip 121. After the limiting member 32 separates from the parallel strip 121, under the action of the clamping spring 21, the two side clamping plates 3 will move towards each other simultaneously, so as to achieve the purpose of clamping the can. After the side clamping plates 3 clamp the can, driven by the sliding frame 2, the side clamping plates 3 will move towards the rear end of the support plate 1. At this time, the limiting member 32 will also move towards the inclined strip 122. After the limiting member 32 abuts against the inclined strip 122 and continues to move the sliding frame 2 backward, because the inclined strip 122 is designed with an inclined structure, when the limiting member 32 contacts the inclined strip 122, under its guiding action, the limiting member 32 will move towards the outside of the support plate 1. This process is used to release the clamped can. During the process of the limiting member 32 moving outward, it will push the stop strip 123 to swing outward until the limiting member 32 separates from the stop strip 123. Under the action of the torsion spring, the stop strip 123 will automatically swing inward until the rear end of the stop strip 123 abuts against the inclined strip 122, thereby closing the gap between the inclined strip 122 and the parallel strip 121 to prevent the limiting member 32 from entering the gap between the inclined strip 122 and the parallel strip 121 again during the process of the sliding frame 2 moving towards the front end of the support plate 1. When the limiting member 32 moves to the outside of the inclined strip 122, the driving element 11 drives the sliding frame 2 to move towards the front end of the support plate 1. At this time, the stop strip 123 has closed the gap between the inclined strip 122 and the parallel strip 121. Therefore, the limiting member 32 can move forward smoothly along the outer side surfaces of the parallel strip 121 and the stop strip 123. During this process, the distance between the two side clamping plates 3 is always in the maximum state to facilitate the next clamping. This structure only needs to reciprocate the sliding frame 2 to automatically control the movement of the side clamping plates 3 along the width direction of the sliding frame 2 by using the guiding assembly 12 and the clamping spring 21.

[0041] Preferably, as Figure 1 , Figure 2 , Figure 6 , Figure 10 andFigure 15 As shown, both sides of the sliding frame 2 are provided with guide rods 22 passing through the lugs 31 along the width direction, and multiple guide rods 22 and lugs 31 are provided along the length direction of the side clamping plate 3. The clamping spring 21 is a cylindrical spring. The outside of the guide rods 22 is sleeved with the clamping spring 21, and the clamping spring 21 is located between the outer end of the guide rod 22 and the lug 31, and the clamping spring 21 is in a compressed state. This scheme uses the guide rods 22 to connect the lugs 31 and the clamping spring 21, which can make the installation structure more compact, and this scheme sets multiple clamping springs 21 along the length direction of the side clamping plate 3, which helps to improve the clamping stability of each section of the side clamping plate 3 on the can. Specifically, a baffle can be set at the outer end of the guide rod 22 to limit the cylindrical spring to prevent the cylindrical spring from falling off, and the end of the cylindrical spring can also be welded to the end of the guide rod 22 to ensure that the end of the cylindrical spring is fixed.

[0042] Further preferably, Figure 1 , Figure 2 , Figure 6 , Figure 10 , Figure 14 and Figure 15 As shown, the ears 31 at the rear ends of the two side clamps 3 are each rotatably provided with a hinge rod 33, and the ends of the two hinge rods 33 are hinged to a connecting block 34, and the ends of the two hinge rods 33 are provided with gears 331, and the two gears 331 are meshed with each other, and the axis of the gear 331 is parallel to the hinge axis of the hinge rod 33 on the connecting block 34. The rear end of the sliding frame 2 is provided with an extension rod 23 along the length direction, and the extension rod 23 passes through the connecting block 34. When the two side clamps 3 have a maximum spacing, there is an obtuse angle between the two hinge rods 33 to prevent the two hinge rods 33 from being in the same straight line after the side clamps 3 move to both sides, resulting in a dead point, affecting the retraction of the two side clamps 3. When the side clamps 3 move along the sliding frame 2 When moving in the width direction, the support ear 31 will drive the hinge rod 33 to swing, and both ends of the hinge rod 33 will swing, and the gears 331 meshing with each other at the ends of the two hinge rods 33 can make the two hinge rods 33 swing in opposite directions at the same angle, thereby reversely controlling the two side clamps 3 to move in opposite directions at the same speed and the same distance, and even if there is a difference in the elastic force of the multiple clamping springs 21, the hinge rod 33 can ensure that the two side clamps 3 move in opposite directions at the same speed and the same distance, thereby ensuring the stability of the two side clamps clamping the can body, and improving the positioning accuracy of the can, ensuring that the can is in the middle part of the sliding frame 2, and preventing the can from deviating toward any side clamp 3.

[0043] Preferably, Figure 1 , Figure 3 , Figure 6 , Figure 7 , Figure 10 , Figure 11 , Figure 15and Figure 16 As shown in the figure, on one side of the baffle 41, guide plates 411 are provided in parallel and at intervals. The lower ends of the guide plates 411 and the baffle 41 are connected by a cross bar 412. The baffle 41 vertically penetrates the bottom of the conveying trough 4, the guide plates 411 penetrate one side of the conveying trough 4, and a support spring 42 is provided at the bottom of the cross bar 412 for providing an upward supporting force to the baffle 41. The outer side of the top of the guide plate 411 has a guiding inclined surface 413.

[0044] When the side clamping plates 3 clamp the cans, the bottom surface of the guide plate 411 contacts the bottom surface of the side clamping plates 3, and the support spring 42 is compressed. At this time, the top of the baffle 41 is lower than the bottom of the conveying trough 4; as Figures 6 to 8 shown in the figure, when the sliding frame 2 moves a predetermined distance towards the rear end of the support plate 1, the guide plate 411 is located in front of the side clamping plates 3. Under the supporting action of the support spring 42, the top of the baffle 41 protrudes upwards from the bottom of the conveying trough 4, forming a blocking structure for the cans. As Figures 10 to 12 and Figure 15 、 Figure 16 shown in the figure, when the two side clamping plates 3 release the cans, the guide plate 411 is located inside the side clamping plates 3. Under the supporting action of the support spring 42, the top of the baffle 41 protrudes upwards from the bottom of the conveying trough 4, forming a blocking structure for the cans.

[0045] In the specific working process, when the two side clamping plates 3 move towards the middle to prepare for clamping the cans, the inner edges of the side clamping plates 3 will be in sliding contact with the guiding inclined surface 413, thereby pushing the guide plate 411 and the baffle 41 to descend together until the side clamping plates 3 are completely above the guide plate 411. At this time, the top of the baffle 41 is lower than the bottom of the conveying trough 4 to facilitate pushing the cans towards the rear end of the conveying trough 4; after the side clamping plates 3 move a predetermined distance towards the rear end of the support plate 1 driven by the sliding frame 2, the guide plate 411 will separate from the front end of the side clamping plates 3 and automatically rise under the action of the support spring 42 to form a blocking effect on the rear cans again. At the same time, the two side clamping plates 3 move outwards simultaneously, and the guide plate 411 will be located inside the side clamping plates 3. After that, moving the sliding frame 2 towards the front end of the support plate 1 will drive the side clamping plates 3 to move forward together to a predetermined position at the front end of the support plate 1, and then moving the side clamping plates 3 towards the middle again can complete the next clamping operation; this structural design can automatically control the movement of the baffle 41 through the cooperation between the side clamping plates 3 and the guiding inclined surface 413 and the cooperation between the side clamping plates 3 and the guide plate 411 when the sliding frame 2 moves to different positions, so that the baffle 41 automatically blocks or releases the cans in the conveying trough 4 at a predetermined position.

[0046] Embodiment 2, a can lid closing system, includes the can arranging and conveying device described in Embodiment 1, as Figures 1 to 13 and Figure 15As shown in the figure, a storage barrel 13 for stacking canned lids is vertically provided in the middle of the top surface of the support plate 1. A through hole 101 is vertically opened at the front end of the support plate 1. The outer circumferential surface of the canned lid is in close contact with the inner wall of the through hole 101, so as to prevent the canned lid from automatically falling from the through hole 101. The specific implementation method can be to set a rubber layer on the inner wall of the through hole 101 or to treat the canned lid made of plastic. It can also be to set a spring piece on the inner wall of the through hole 101 to block the falling of the canned lid. When the canned lid is subjected to a downward pressure, the spring piece can be pushed to compress, so that the canned lid is moved downward from the through hole 101 under the action of the pressure. The storage barrel 13 and the through hole 101 are on the same line at the front and rear ends of the support plate 1 and are located directly above the conveying groove 4; A push plate 24 facing the front end is provided at the rear end of the sliding frame 2. The thickness of the push plate 24 is less than or equal to the thickness of the canned lid. A through hole 131 for passing through the push plate 24 is opened at the bottom of the storage barrel 13 along the direction of the connection line of the front and rear ends of the support plate 1.

[0051] Embodiment 3, a method for closing the can lid, which is realized by using the can lid closing system described in Embodiment 2. The lid closing method includes the following steps: S1: Push the can cover. Use the driving element 11 to push the sliding frame 2 forward, and push the can cover at the bottom of the storage barrel 13 to above the through hole 101 through the push plate 24. S2: Clamp and position. The sliding frame 2 moves forward to a predetermined position at the front end of the support plate 1. The two side clamping plates 3 synchronously close towards the middle, and clamp the can blocked by the baffle 41 through the first card slot 301 at the front end, and clamp the cans arranged behind in the conveying groove 4 through the remaining card slots 301 of the side clamping plates 3. The baffle 41 is removed from the inside of the conveying groove 4 to remove the blocking effect on the cans. S3: Push the can. Use the driving element 11 to push the sliding frame 2 backward, so that the sliding frame 2 moves to a predetermined position at the rear end of the support plate 1. The baffle 41 is inserted into the conveying groove 4 again to block the cans at the rear. The two side clamping plates 3 move to both sides at the same time to release the cans. The released cans are coaxially located below the through hole 101. The pressing plate 15 presses the can cover above the through hole 101 into the through hole 101, and uses the tight contact method between the can cover and the through hole 101 to temporarily store the can cover in the through hole 101. S4: Close the lid. Use the driving element 11 to continue pushing the sliding frame 2 backward. At this time, since the side clamping plates 3 have released the cans in step S3, when the sliding frame 2 is continuously pushed in this step, the cans arranged on the conveying groove 4 will not move further. Use the front border of the sliding frame 2 to continue pushing the rotating plate 14 to rotate downward, and use the pressing plate 15 to press the can cover in the through hole 101 to the top of the can. By repeating steps S1 to S4, the cans can be continuously arranged and conveyed, and the lid closing process can be completed during the arrangement and conveyance. Moreover, by integrating the lid closing process into the arrangement and conveyance device, the driving element 11 of the arrangement and conveyance device can be used to synchronously complete the lid closing process, which can effectively reduce the setting of power elements and avoid designing a complex control system.
