Description

Technical Field

[0001] The present application relates to the technical field of cover production equipment, and in particular to a cover stacking device. Background Art

[0002] In the field of disposable paper covers and plastic covers production, in order to reduce manpower input and improve work efficiency, an automatic stacking device that can automatically stack the covers into piles to facilitate the packing of the whole pile is usually set at the rear end of the cover production line and the inspection line. For example, Chinese patent CN1172018642A discloses a paper cover stacking device, which is provided with at least one stacking mechanism at the output end of the conveying mechanism, and the stacking mechanism includes a bracket and a lifting column, a support platform, a driving assembly, a limiting column and an elastically deformable arc support plate assembly arranged on the bracket, the lifting column is slidably connected to the lifting column, and a through hole for the lifting column to pass through is arranged on the support platform; the driving assembly is connected to the lifting column, and is used to move the lifting column along the axis direction of the through hole; the arc support plate assembly and the limiting column are both distributed and arranged at the edge of the through hole; when the paper cover comes to the support platform, under the action of the driving assembly, the lifting column moves upward and passes through the through hole to push the paper cover onto the arc support plate assembly, and circulates in sequence, thereby realizing the stacking of multiple paper covers.

When the trajectory of the paper cover entering the support platform of the stacking mechanism is not straight or is obstructed by other factors, the paper cover will not be able to align with the through hole on the support platform, which will cause the lifting column to be unable to smoothly lift the paper cover from the center of the paper cover to the top of the arc-shaped support part assembly, causing the paper cover to flip over or even the edge of the paper cover to be impacted and damaged.

DETAILED DESCRIPTION

[0032] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0033] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0034] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0035] In the field of disposable paper covers and plastic covers production, in order to reduce manpower input and improve work efficiency, an automatic stacking device that can automatically stack the covers into piles to facilitate the packing of the whole pile is usually set at the rear end of the cover production line and the inspection line. For example, Chinese patent CN1172018642A discloses a paper cover stacking device, which is provided with at least one stacking mechanism at the output end of the conveying mechanism, and the stacking mechanism includes a bracket and a lifting column, a support platform, a driving assembly, a limiting column and an elastically deformable arc support plate assembly arranged on the bracket, the lifting column is slidably connected to the lifting column, and a through hole for the lifting column to pass through is arranged on the support platform; the driving assembly is connected to the lifting column, and is used to move the lifting column along the axis direction of the through hole; the arc support plate assembly and the limiting column are both distributed and arranged at the edge of the through hole; when the paper cover comes to the support platform, under the action of the driving assembly, the lifting column moves upward and passes through the through hole to push the paper cover onto the arc support plate assembly, and circulates in sequence, thereby realizing the stacking of multiple paper covers.

[0036] Although the paper cover stacking device of the prior art can realize automatic stacking operation, it still has defects: the stacking mechanism is arranged at the output end of the conveying mechanism, and the paper cover can only rely on the inertia of the paper cover itself when entering the stacking mechanism from the conveying mechanism. When the trajectory of the paper cover entering the support platform of the stacking mechanism is not straight or is obstructed by other factors, the paper cover will not be able to align with the through hole on the support platform, which will cause the lifting column to be unable to smoothly lift the paper cover from the center of the paper cover to the top of the arc-shaped support part assembly, causing the paper cover to flip over or even the edge of the paper cover to be impacted and damaged.

[0037] In order to overcome the above technical problems, refer to Figure 1-4 The present embodiment provides a cover stacking device, including a first conveying mechanism 10, a second conveying mechanism 20, and a stacking mechanism 30 and a lifting mechanism 40 respectively arranged above and below the second conveying mechanism 20. During operation, the first conveying mechanism 10 conveys the cover 60 to the second conveying mechanism 20, and the second conveying mechanism 20 continues to push the cover 60, so that the cover 60 can be accurately aligned above the lifting mechanism 40, so that the lifting mechanism 40 can align with the center of the cover 60 and stably lift the cover 60 upward, overcoming the problem in the traditional solution that the lifting column cannot smoothly lift the paper cover from the center of the paper cover to the top of the arc-shaped support part assembly, causing the paper cover to flip over or even impact and damage the edge of the paper cover.

[0038] In the specific structure of the present scheme, the first conveying mechanism 10 has a plurality of conveying channels 11; specifically, the first conveying mechanism 10 has a wide conveyor belt, and a plurality of partition plates are provided on the conveyor belt to separate a plurality of conveying channels 11. After the cover body 60 produced or inspected in the front falls onto the conveyor belt, it is evenly dispersed into each conveying channel 11, and the continuously running conveyor belt pushes each cover body 60 onto the second conveying mechanism 20.

[0039] The second conveying mechanism 20 is connected to the rear end of the first conveying mechanism 10, and has a plurality of conveying units 21 corresponding to the conveying channels 11 one by one, each of the conveying units 21 includes two conveying belts 211 arranged at intervals, and a lifting space for allowing the cover body 60 to pass through is formed between the two conveying belts 211; specifically, each conveying unit 21 of the second conveying mechanism 20 is just allowed to convey one cover body 60, and the width of the lifting space needs to be smaller than the width of the cover body 60, so that the cover body 60 can be pushed across the two conveying belts 211; and the width of the lifting space needs to be larger than the width of the lifting unit 41, so that the lifting unit 41 can lift the cover body 60 upward without obstacles.

[0040] The stacking mechanism 30 is installed above the second conveying mechanism 20 and has a plurality of stacking units 31 corresponding to the conveying units 21 one by one; the stacking units 31 can stack the covers 60 lifted by the lifting mechanism 40 one by one, so as to sort and gather the covers 60.

[0041] The lifting mechanism 40 is installed below the second conveying mechanism 20, and has a plurality of lifting units 41 corresponding one to one with the conveying units 21. The lifting unit 41 can lift the cover body 60 on the conveying unit 21 upward into the stacking unit 31 through the lifting space; the lifting unit 41 can lift the cover body 60 above the conveying unit 21 upward one by one into the stacking unit 31, thereby realizing the function of automatic stacking.

[0042] In summary, the cover stacking device based on this embodiment can automatically stack products such as disposable paper covers and plastic covers. The cover stacking device of this solution is connected to the second conveying mechanism 20 at the rear end of the first conveying mechanism 10. The stacking mechanism 30 and the top-loading mechanism 40 are respectively arranged above and below the second conveying mechanism 20. The second conveying mechanism 20 is provided with a plurality of conveying units 21. Each conveying unit 21 is provided with two conveying belts 211 arranged at intervals. When the cover 60 is transported to the end of the first conveying mechanism 10, it will continue to be pushed to the second conveying mechanism 20. The two conveying belts 211 of the second conveying mechanism 20 continue to operate and continue to provide a pushing force to the cover 60, so that the cover 60 can be accurately moved to the top of the top-loading mechanism 40. The top-loading mechanism 40 can automatically lift the cover 60 from the center of the cover 60 and stack it in the stacking mechanism 30, thereby realizing a stable and orderly automatic stacking function. Compared with the prior art method of solely utilizing the inertia of the cover body 60 itself to push the cover body 60 into the stacking mechanism, the present solution arranges a second conveying mechanism 20, which can continuously provide propulsion force for the cover body 60 without hindering the lifting mechanism 40 from lifting the cover body 60 upward, thereby avoiding problems such as the cover body 60 being obstructed and unable to align with the lifting mechanism 40, causing the cover body 60 to flip over, and the edge of the cover body 60 to be damaged by impact.

[0043] In one embodiment, referring to Figure 5 Each of the conveying units 21 includes two first pulleys 212 and two second pulleys 213, and each of the conveying belts 211 is sleeved on one of the pulleys and one of the second pulleys 213; in the second conveying mechanism 20, all of the first pulleys 212 are coaxially arranged, and all of the second pulleys 213 are coaxially arranged, and the second conveying mechanism 20 includes a first support shaft 24 and a second support shaft 25, and the first support shaft 24 is connected in series to all of the first pulleys 212, and the second support shaft 25 is connected in series to all of the second pulleys 213.

[0044] Specifically, the first support shaft 24 and the second support shaft 25, in addition to supporting the first pulley 212 and the second pulley 213, can also be used as a driving shaft to drive the first pulley 212 and the second pulley 213 to operate. Taking the first support shaft 24 as an example, when it only provides a support function for the first pulley 212, it can be fixedly installed. At this time, the first pulley 212 needs to be rotatably installed on the first support shaft 24, so that the first pulley 212 can drive or follow the conveyor belt 211 to rotate; when the first support shaft 24 also serves as a driving shaft, the first support shaft 24 needs to be rotatably installed, and the first pulley 212 needs to be fixedly installed on the first support shaft 24. When the mechanism is running, it only needs to drive the first support shaft 24 to rotate, so that all conveyor belts 211 can be driven to operate. Obviously, this structure has the advantages of simple structure and good synchronization. The setting of the second support shaft 25 can refer to the description of the first support shaft 24 mentioned above. In the specific setting, preferably, only one of the first support shaft 24 and the second support shaft 25 needs to be rotated to serve as the driving shaft, and the other one can be fixed.

[0045] In one embodiment, referring to Figure 5 The conveying unit 21 includes a driving mechanism 23, which includes a driving motor 231, a driving wheel 232, a driven wheel 233 and a synchronous belt 234. The driving wheel 232 is connected to the output shaft of the driving motor 231, the driven wheel 233 is connected to the end of the first support shaft 24, and the synchronous belt 234 is sleeved on the driving wheel 232 and the driven wheel 233.

[0046] This solution only has one driving mechanism 23 to drive all the conveyor belts 211, which has the advantages of simple structure and low cost. The combination of a driving motor 231, a driving wheel 232, a driven wheel 233 and a synchronous belt 234 is used to drive the conveyor belt 211. This design has the advantages of compact structure, high transmission efficiency and good synchronization.

[0047] In one embodiment, referring to Figure 5 The second conveying mechanism 20 includes a mechanism bracket 22, and the mechanism bracket 22 includes a bracket bottom plate 221 and a plurality of support vertical plates 222 parallel to and erected on the bracket bottom plate 221, and bearings 223 are arranged on the support vertical plates 222, and the first support shaft 24 passes through each of the bearings 223; the bracket bottom plate 221 is provided with a plurality of top material holes 2211 corresponding to the top material spaces one by one; the driving motor 231 is arranged below the bracket bottom plate 221, and the bracket bottom plate 221 is provided with a avoidance hole 2212 for allowing the synchronous belt 234 to pass through.

[0048] The mechanism support 22 formed by the combination of the support bottom plate 221 and the parallel vertical support plate 222 provides a stable support foundation for the entire conveying mechanism. This structure can ensure the stability and reliability of the cover 60 conveying. A bearing 223 is set on the vertical support plate 222, and the first support shaft 24 is supported by the bearing 223. This design allows the first support shaft 24 to rotate smoothly and improves the transmission efficiency. The drive motor 231 is set below the support bottom plate 221. This layout not only saves space, but also makes the structure of the entire conveying mechanism more compact.

[0049] In one embodiment, referring to Figure 6 The mechanism bracket 22 also includes a plurality of material guide plates 26 corresponding one by one to the top material space, and the material guide plates 26 include a vertical support portion and a horizontal guide portion vertically connected, the vertical support portion is upright and fixed on the bracket bottom plate 221, and the horizontal guide portion covers above the first support shaft 24.

[0050] Specifically, the first support shaft 24 is a support shaft arranged near the first conveying mechanism 10. When the cover 60 is conveyed to the conveyor belt 211, it needs to pass over the first support shaft 24. However, since a certain distance is maintained between the two conveyor belts 211, it is inevitable that when the cover 60 is tilted, it will fall into the top material space of the two conveyor belts 211, and then rub against the rotating first support shaft 24, which may damage the cover 60 and interfere with the normal operation of the first support shaft 24. In this solution, a guide plate 26 is provided, and the horizontal guide portion of the guide plate 26 is used to cover the top of the first support shaft 24, so that the cover 60 can be smoothly guided to pass over the first support shaft 24, thereby preventing the cover 60 from falling onto the first support shaft 24 and causing the aforementioned problems.

[0051] In one embodiment, the second conveying mechanism 20 also includes a rear material stopper rack 27, which includes a support frame 271 and a plurality of material stopper plates 272 installed on the support frame 271 and corresponding one-to-one to the top material space, and the material stopper plates 272 are arranged opposite to the conveying channel 11. The material stopper plates 272 limit the conveying distance of the cover body 60 on the conveying unit 21, so that the cover body 60 can be aligned with the top material unit 41 and the stacking unit 31.

[0052] Specifically, the setting of the rear material stopper can block the cover body 60 just above the top material unit 41. When the cover body 60 contacts the rear material stopper 27, even if the conveyor belt 211 continues to operate, the cover body 60 will be blocked by the rear material stopper 27 and cannot move forward. At this time, the cover body 60 is just aligned with the top material unit 41. The rise of the top material unit 41 can directly lift it up from the center of the cover body 60, avoiding the problem of the cover body 60 being tilted or damaged.

[0053] In one embodiment, the baffle plate 272 is provided with an adjustment long hole, and a locking bolt passes through the adjustment long hole and is locked on the support frame 271. Based on the sliding of the adjustment long hole relative to the locking bolt, the distance between the baffle plate 272 and the conveying channel 11 can be adjusted.

[0054] Specifically, the position of the baffle plate 272 can be adjusted by loosening the locking bolt, and the baffle plate 272 can be fixed by tightening the locking bolt. This structure can facilitate the position of the baffle plate 272 to be adaptively adjusted according to the size of the cover body 60, thereby adjusting the positioning position of the cover body 60 after transportation, and meeting the stacking requirements of covers 60 of different sizes.

[0055] In one embodiment, referring to Figure 7-8 The stacking unit 31 includes a support frame 311 and a plurality of check assemblies 312 and a plurality of guide rods 313 installed on the support frame 311. The cover body 60 can pass through the check assembly 312 in one direction from bottom to top. Through the support of the check assembly 312, the cover body 60 can be stacked between the guide rods 313.

[0056] Through the cooperation of the non-return assembly 312 and the guide rod 313, the stacking unit 31 can achieve stable stacking of the cover bodies 60. This design makes it difficult for the stacked cover bodies 60 to collapse or misalign, which provides convenience for subsequent processing and transportation.

[0057] Preferably, the non-return assembly 312 includes a mounting seat 3121 and a supporting block 3122. The mounting seat 3121 is fixed around the support frame 311. The supporting block 3122 is a wedge-shaped block, which is rotatably mounted on the mounting seat 3121. The mounting seat 3121 and the supporting block 3122 are provided with springs. When the lifting unit 41 lifts the cover body 60 upward, the edge of the cover body 60 will push each supporting block 3122 to flip upward. After the cover body 60 passes over the supporting block 3122, the spring force will automatically push the supporting block 3122 back to its original position. After the lifting unit 41 falls, the cover body 60 is supported on the supporting block 3122, thereby achieving the purpose of automatic stacking.

[0058] In one embodiment, the pushing unit 41 includes a pushing cylinder 411 and a pushing head 412 connected to the end of a piston rod of the pushing cylinder 411. The pushing head 412 is aligned with the bottom of the stacking unit 31. The pushing head 412 is driven to rise and fall by the extension and contraction of the pushing cylinder 411, so as to push the cover body 60 upward into the stacking unit 31.

[0059] The ejection cylinder 411 is used to drive the ejection head 412 to rise and fall to realize the ejection function. This structure has the advantages of mature technology, good reliability and easy implementation.

[0060] In one embodiment, a quantitative mechanism 50 is further included, and the quantitative mechanism 50 is installed above the stacking mechanism 30, and includes a plurality of quantitative units corresponding to the stacking units 31 one by one, and the quantitative units include a lifting drive module, a horizontal drive module and a supporting claw, and the supporting claw is connected to the horizontal drive module, and the horizontal drive module is connected to the lifting drive module. Through the cooperation of the horizontal drive module and the lifting drive module, the supporting claw can quantitatively lift the cover body 60 stacked in the stacking unit 31.

[0061] Specifically, the quantitative mechanism 50 is used to quantitatively stack the stacked covers 60 to facilitate the subsequent quantitative packing work. Figure 6 In the second conveying mechanism 20, a counter 28 corresponding to each conveying unit 21 is also provided. The counter 28 is linked to the control of the quantitative mechanism 50. It can be understood that based on the counter 28, the number of cover bodies 60 stacked in the stacking unit 31 can be automatically calculated. When the set number is reached, the quantitative mechanism 50 automatically lifts the stacked stack of cover bodies 60, and then other unloading devices are used to take out the stacked fixed number of cover bodies 60 for packing.

[0062] When the quantitative mechanism 50 is working specifically, after receiving the start command, the lifting drive module drives the horizontal drive module and the material supporting claws to move to the position under the cover body 60, and then the horizontal drive module drives the material supporting claws to extend horizontally, and the material supporting claws move to just below the cover body 60, and the lifting drive module drives the horizontal drive module to lift, thereby realizing the automatic stacking function; when the cover body 60 lifted by the material supporting claws is taken out, the horizontal drive module drives the material supporting claws to retract and reset, and this cycle is repeated.

[0063] In other embodiments, after the quantitative mechanism 50 stacks the cover bodies 60 in a quantitative manner, the quantitative cover bodies 60 may be directly taken out manually.

[0064] The length of the guide rod 313 can be set specifically according to the quantitative stacking height of the cover body 60. In order to facilitate mechanical or manual lifting of the entire stack of cover bodies 60 out of the restricted range of the guide rod 313, the height of the guide rod 313 can be appropriately reduced according to actual conditions.
