Description

Technical Field

[0001] The utility model relates to the technical field of packaging box palletizing, in particular to a palletizing device for producing paper packaging boxes. Background Art

[0002] With the rapid development of the express delivery industry, cartons are the most widely used packaging products. According to different materials, there are corrugated cartons, single-layer cardboard boxes, etc., with various specifications and models. Cartons are usually used as wrapping materials for goods or as outer protective materials for items. After the production and processing of cartons are completed, the cartons need to be stacked and bundled, and then the folded cartons are transported and assembled after being transported to the designated place. Therefore, a carton stacking device is needed.

[0003] Since cartons are often in the form of flat cardboard during production and processing for transportation and stacking, and are then shaped and fixed to hold goods, existing carton production stacking devices mostly use suction cups to adsorb and then stack the cartons on pallets, which results in adsorption and stacking from top to bottom layer by layer at a time, with a slow cycle and low efficiency. In addition, the packaging boxes in the stack cannot be integrated during the stacking process, resulting in the stacked packaging boxes gradually tilting as they are continuously stacked and raised, and are prone to tipping over. Especially during the stacking process, if the packaging boxes are not limited, shaking and misalignment are likely to occur. These factors will eventually lead to overall tilting and tipping over.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The packaging boxes inside the stacking rack can be integrated through the integration mechanism. The two sets of integration plates are driven to move toward each other through the extension and contraction of the cylinders on both sides to clamp the packaging boxes inside on both sides, thereby playing the role of integration and shaping. At the same time, the rotation of the rotating motor can drive the rotating seat to rotate on the swing seat, thereby driving the two sets of thrust plates to swing at the same time to clamp and integrate the other two sides of the packaging boxes. The packaging boxes can be neatly stacked together by cooperating with the integration mechanism. At the same time, during the transmission process, the four sides are clamped to avoid looseness and collapse.

[0017] The integrated packaging boxes will be moved to the designated stacking position for stacking under the drive of the guide mechanism. After the packaging boxes are stacked, the transport rack will be pulled out from the bottom of the packaging boxes.

At this time, the other set of thrust plates will remain stationary to play a thrust-stopping role, preventing the friction inertia of the transport rack from driving the stacked packaging boxes to deviate during the withdrawal process, causing the stacked packaging boxes to be misaligned and unstable.

[0018] The transmission bars on the conveyor belt and the transport struts on the transport rack are staggered. This arrangement allows one batch of cartons to be integrated and palletized while another batch of cartons can be moved to a designated location by the transport mechanism. At this time, the transport rack can be directly inserted horizontally between the transmission bars, and can directly drive the cartons to move for integration and palletizing by rising, thereby improving the rhythm and work efficiency. Moreover, this design of directly lifting the packages from the bottom for palletizing can drive multiple groups of cartons for palletizing at one time, which is more efficient than the adsorption transport palletizing that can only drive the top layer of cartons at a time.

[0019] This arrangement can use the guiding mechanism to drive the transport rack and the stacking rack to move and cooperate in the stacking operation respectively without interfering with each other, thereby improving work efficiency. By connecting the cylinder frame with the lifting assembly and the sliding assembly and coordinating through program control therebetween, the stacking rack can move up, down, left and right, so as to more flexibly drive the packaging boxes to move for stacking operations.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 7The utility model provides an embodiment: a stacking device for producing paper packaging boxes, comprising a transport mechanism, a base 32, a side plate 33, a transport frame 10 and a stacking frame 16, wherein a steel plate is welded on the top surface of the base 32, and the side plates 33 are symmetrically welded on both sides of the steel plate. Both inner and outer surfaces of the two side walls of the stacking frame 16 are equipped with guide mechanisms with opposite guides, and an integration mechanism is installed on the two side walls of the stacking frame 16, and the integration mechanism is composed of a cylinder seat 20, an integration plate 21 and a cylinder 19. The cylinder seat 20 is symmetrically installed on the outer walls of the two sides of the stacking frame 16 by bolts, and the cylinder 19 is fixedly installed on the cylinder seat 20, and the output end of the cylinder 19 passes through the two side walls of the stacking frame 16. And it is fixedly connected to one side wall of the integration plate 21. The device can drive the transport rack 10 to move to the side of the packaging box to be stacked and drive it to the inside of the stacking rack 16 by setting two sets of guiding mechanisms with opposite directions. At this time, the packaging box inside can be integrated through the set integration mechanism, and the two sets of integration plates 21 are driven to move toward each other by the extension and contraction of the cylinders 19 on both sides to clamp the packaging box inside on both sides, thereby playing the role of integration and shaping, avoiding misalignment when stacking the packaging boxes, which may cause them to collapse easily. The integrated packaging boxes will be moved to the designated stacking position for stacking under the drive of another set of guiding mechanisms.

[0030] Specifically, swing seats 17 are symmetrically welded on both sides of the top surface of the stacking frame 16, and a rotating motor 24 is fixedly installed on one side wall of the swing seat 17. The output end of the rotating motor 24 passes through the rotating seat 23 and is plugged into the inner wall of the rotating seat 23, and the output end of the rotating motor 24 is rotatably connected to the inner wall of one side of the swing seat 17 through a bushing. A thrust plate 22 is fixedly installed on one side of the rotating seat 23. When the packaging box is transported to the inner side of the stacking frame 16 for integration, the rotation of the rotating motor 24 can drive the rotating seat 23 to rotate on the swing seat 17, thereby driving the two sets of thrust plates 22 to swing at the same time, so as to stack the other two sides of the packaging box. The clamping integration can make the packaging boxes neatly stacked together by cooperating with the integration mechanism. At the same time, by clamping them on all sides during the transmission process, looseness and collapse can be avoided. After the packaging boxes are stacked, the transport rack 10 will be pulled out from the bottom of the packaging boxes. During this process, the thrust plates 22 in the opposite direction of the movement of the transport rack 10 will be retracted. At this time, the other set of thrust plates 22 remain stationary to play a thrust role, thereby preventing the friction inertia of the transport rack 10 from causing the stacked packaging boxes to shift during the withdrawal process, resulting in misaligned and unstable stacking.

[0031] Specifically, the guiding mechanism is composed of a cylinder frame 15, a power cylinder 14 and a connecting seat 12. The power cylinder 14 is embedded in the inner wall of the cylinder frame 15, and the output end of the power cylinder 14 is fixedly connected to the connecting seat 12. Two groups of mounting holes are opened on the connecting seat 12. The extension and retraction of the power cylinder 14 can drive the support arm connected to the connecting seat 12 to move, thereby achieving the purpose of transporting the packaging box.

[0032] Specifically, four groups of cylinder frames 15 are provided, of which two groups of cylinder frames 15 are symmetrically installed on the inner walls on both sides of the stacking rack 16, and the other two groups of cylinder frames 15 are locked and connected with the guide seat 29 and the slide seat 30 respectively. The guide seat 29 and the slide seat 30 are respectively installed in the lifting assembly and the sliding assembly. By connecting the cylinder frame 15 with the lifting assembly and the sliding assembly, and through the program control and coordination therebetween, the stacking rack 16 can move up, down, left and right, so as to more flexibly drive the movement of the packaging box for stacking operations.

[0033] Specifically, the connecting seat 12 and the locking bolt 13 on the power cylinder 14 in the two groups of cylinder frames 15 located on the inner side of the stacking rack 16 are fixedly connected to the first arm 11, and the connecting seat 12 and the locking bolt 13 on the power cylinder 14 in the other two groups of cylinder frames 15 are fixedly connected to the second arm 18. The first arm 11 and the second arm 18 are respectively fixedly connected to the two side walls of the transport rack 10 and the stacking rack 16. This arrangement can drive the transport rack 10 and the stacking rack 16 to move and cooperate to perform stacking operations through the guiding mechanism without interfering with each other, thereby improving work efficiency.

[0034] Specifically, the lifting assembly is composed of a servo motor 25, a base 26, fixing bolts 27, a guide seat 29 and a threaded guide column 34. The inner walls on both sides of the side plate 33 are provided with a slide groove 28. The base 26 is connected to the top surface of the side plate 33 by two sets of fixing bolts 27. The servo motor 25 is installed on the base 26, and the output end of the servo motor 25 is fixedly connected to the top of the threaded guide column 34 by a coupling. The bottom end of the threaded guide column 34 passes through the slide groove 28 and is embedded in the inner wall of the side plate 33 through a bearing. The guide seat 29 is threadedly connected to the outer end of the threaded guide column 34. As the stacking of the packaging boxes continues to increase, the stacking rack 16 can be driven to rise and cooperate through the provided lifting assembly. The rotation of the servo motor 25 can drive the threaded guide column 34 to rotate. Under the rotation of the threaded guide column 34, the guide seat 29 will move up and down in the slide groove 28 for lifting. The lifting and lowering of the guide seat 29 synchronously drives the lifting and lowering of the stacking rack 16.

[0035] Specifically, the sliding assembly consists of a slide seat 30 and a slide rod 31. The slide rod 31 is installed in the inner wall of the slide groove 28, and the slide seat 30 is slidably connected to the outer wall of the slide rod 31. When the lifting assembly drives the stacking rack 16 to move, the slide seat 30 on the other side of the stacking rack 16 will slide in the slide rod 31 to assist its stable movement.

[0036] Specifically, the transport mechanism is provided with two groups, and the two groups of transport mechanisms are symmetrically arranged on both sides of the side plate 33, and the transport mechanism frame 1, the transmission belt 2, the driven roller 3, the rolling bearing 4, the bearing groove 5, the mounting seat 6, the transmission motor 7, the active roller 8 and the support plate 9, the support plate 9 is installed in the middle of the frame 1, and the active roller 8 and the driven roller 3 are respectively arranged on both sides of the support plate 9, the transmission belt 2 is sleeved on the outer ends of the active roller 8 and the driven roller 3, and both ends of the active roller 8 and the driven roller 3 are embedded in the bearing groove 5 opened on the inner wall of the frame 1 through the rolling bearing 4, and the active roller One end of 8 passes through the bearing slot 5 and is connected to the output end of the transmission motor 7. The transmission motor 7 is installed on a side wall of the frame 1 through the mounting seat 6. Two sets of transport mechanisms are provided to uniformly move the packaging boxes to one side of the stacking rack 16 for collection, and after being integrated by the stacking rack 16, the packaging boxes are moved to the other side for stacking. Finally, driven by the transport mechanism, the stacked packaging boxes will be uniformly moved out. When the transport mechanism needs to be operated, the transmission motor 7 is started. Under the rotation of the transmission motor 7, the active roller 8, the driven roller 3 and the conveyor belt 2 will rotate simultaneously to perform the transport operation.

[0037] Specifically, a plurality of groups of transmission bars are equidistantly arranged on the conveyor belt 2, and a plurality of groups of transport struts are equidistantly arranged on the transport rack 10. The plurality of transport struts and the transmission bars are staggered. This arrangement allows a batch of packaging boxes to be integrated and stacked while another batch of packaging boxes can be moved to a designated location under the drive of the transport mechanism. At this time, the transport rack 10 can be directly inserted horizontally between the transmission bars, and can directly drive the packaging boxes to move for integration and stacking by rising, thereby improving the rhythm and work efficiency.

[0038] Working principle: when in use, two groups of transport mechanisms are set up to uniformly move the packaging boxes to one side of the stacking rack 16 for collection, and after being integrated by the stacking rack 16, the packaging boxes are moved to the other side for stacking. Finally, driven by the transport mechanism, the stacked packaging boxes will be uniformly moved out. When the transport mechanism needs to be operated, the transmission motor 7 is started. Under the rotation of the transmission motor 7, the active roller 8, the driven roller 3 and the conveyor belt 2 will rotate simultaneously to perform the transportation operation. By setting two groups of guiding mechanisms with opposite guides, the transport rack 10 can be driven to move to the side of the packaging box to be stacked and driven to the inside of the stacking rack 16. At this time, the packaging boxes inside it can be integrated through the set integration mechanism, and the two groups of integration plates 21 are driven to move toward each other by the extension and contraction of the cylinders 19 on both sides to clamp the packaging boxes inside on both sides, thereby playing a role of integration and shaping, avoiding misalignment when the packaging boxes are stacked, which may cause them to collapse easily. The integrated packaging boxes will be moved to the designated stacking position driven by another group of guiding mechanisms. For palletizing, when the packaging box is transported to the inner side of the stacking rack 16 for integration, the rotation of the rotating motor 24 can drive the swivel seat 23 to rotate on the swing seat 17, thereby driving the two sets of thrust plates 22 to swing at the same time to clamp and integrate the other two sides of the packaging box. By cooperating with the integration mechanism, the packaging box can be neatly stacked together. At the same time, by clamping it all around during the transmission process, looseness and collapse can be avoided during the process. After the packaging box is stacked, the transport rack 10 will be pulled out from the bottom of the packaging box. During this process, the thrust plate 22 in the opposite direction of the movement of the transport rack 10 will be retracted. At this time, the other set of thrust plates 22 remains stationary and plays a thrust role to prevent the friction inertia of the transport rack 10 from driving the stacked packaging boxes to deviate during the extraction process, resulting in the occurrence of unstable stacking. By connecting the cylinder rack 15 with the lifting assembly and the sliding assembly, the stacking rack 16 can move up, down, left and right through the program control and cooperation between them, so as to more flexibly drive the packaging box to move for palletizing operations.
