Description

Technical Field

[0001] The present invention belongs to the technical field of production line sorting, and particularly relates to an automatic sorting mechanism for cartons that prevents scattering. Background Art

[0002] When packing small boxes in batches on a production line, it is necessary to first sort the small boxes. After arranging them neatly, they are uniformly clamped into the box by a fixture. In the sorting process, it is necessary to stack the small boxes conveyed by the production line into columns, and then stack the columns of small boxes into sheets. When the existing sorting devices sort easily deformable small boxes, it is easy to have insufficient positioning and excessive extrusion, resulting in the scattering of small boxes. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic sorting mechanism for cartons that prevents scattering in order to solve the above problems.

[0004] The present invention achieves the above purpose through the following technical solutions:

[0005] An automatic sorting mechanism for cartons that prevents scattering includes a feeding mechanism for conveying small boxes, and also includes the following mechanisms:

[0006] A box-topping mechanism: used to receive the small boxes conveyed by the feeding mechanism, including a single-box channel for arranging the small boxes one by one, rollers provided on the side walls of the single-box channel, a full-material detection member provided at the end of the single-box channel, and a jacking assembly for jacking up the small boxes;

[0007] A box-supporting mechanism: used to receive the small boxes jacked up by the box-topping mechanism and stack them vertically, including two clamping plates, a long plate located inside the two clamping plates, and a supporting plate hinged at the bottom end of the long plate. A limiting member for limiting is provided between the supporting plate and the long plate;

[0008] A front-pushing mechanism and a rear-pushing mechanism: used to transfer the small boxes in the box-supporting mechanism to the flipping mechanism. The front-pushing mechanism includes a front-pushing plate and a driving assembly, and the rear-pushing mechanism includes a rear-pushing plate and a stroke assembly;

[0009] A flipping mechanism: used to flip the vertically stacked small boxes to horizontal, including a fixed plate and a rotating plate, and a stroke cylinder for driving the rotating plate to lie flat.

[0010] As a further optimized solution of the present invention, the feeding mechanism includes a frame body, a conveyor belt provided on the frame body, a clamping channel provided at the upper end of the frame body, and an adjusting member for adjusting the position of the clamping channel. The feeding mechanism is provided with a clamping channel to limit the traveling direction of the small boxes so that they are aligned with the single-box channel.

[0011] As a further optimized solution of the present invention, a pressing wheel for flattening the small boxes and an adjusting member for adjusting the position of the pressing wheel are provided at the end of the feeding mechanism. The pressing wheel is used to press the small boxes neatly so that the small boxes enter the single-box channel flatly.

[0012] As a further optimized solution of the present invention, the lifting assembly includes a lifting cylinder and a lifting member disposed below the single-box channel. At least two parallel cross bars are provided at the top end of the lifting member, and the cross bars are located in the gaps between the rollers, facilitating up and down movement, and lifting the neatly arranged small boxes upward.

[0013] As a further optimized solution of the present invention, the box supporting mechanism includes two outer frames disposed above the single-box channel. The outer frames are arranged around the periphery of the clamping plate. A guide rod and a slider cylinder sliding on the surface of the guide rod are provided between the upper and lower frames of the outer frame. The slider cylinder extends to the inner side of the clamping plate through a cross arm and is fixedly connected to the long plate. The box supporting mechanism is used to support the bottom of the small boxes lifted by the lifting mechanism, and then stack them layer by layer into a sheet. Among them, the clamping plate is used to limit the small boxes on both sides, and the front push plate and the rear push plate are used to limit the small boxes in the middle of the clamping plate at both ends.

[0014] As a further optimized solution of the present invention, the flipping mechanism includes a fixed rod, which is hinged to a rotating plate. An L-shaped convex frame for placing small boxes and a clamping plate for clamping small boxes are provided on the surface of the rotating plate close to the fixed plate. The clamping plate is driven by a clamping cylinder. The flipping mechanism is used to lay flat the vertically stacked small boxes neatly, facilitating subsequent packing into boxes.

[0015] As a further optimized solution of the present invention, the frame of the front pushing mechanism is disposed above the feeding mechanism. The driving assembly includes a first motor disposed on the frame, a toothed belt driven by the first motor, and a sliding member fixedly connected to the toothed belt. The lower part of the sliding member is fixedly connected to the front push plate. The front pushing mechanism is used to push the small boxes from the middle of the clamping plate into the flipping mechanism.

[0016] As a further optimized solution of the present invention, the rear pushing mechanism is disposed at the rear end of the flipping mechanism away from the feeding direction. The stroke assembly is disposed at the upper end of the base and is driven by a second motor. The output end of the stroke assembly is provided with a rear push plate passing through the gap between the rotating plate and the fixed plate. The function of the rear pushing mechanism is the same as that of the front pushing mechanism.

[0017] The beneficial effects of the present invention are as follows:

[0018] By the mutual cooperation among the box lifting mechanism, the box supporting mechanism, the front pushing mechanism, the rear pushing mechanism and the flipping mechanism, the present invention enables the relatively small packaging boxes to be assembled into a sheet before packing, and has multi-sided limiting throughout the process of material collection, effectively preventing the problems of deformation and scattering of the small boxes, greatly improving the efficiency of small box sorting and packing, and being applicable to the high-speed operation of the production line.

[0028] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0029] Embodiment 1

[0030] As Figure 1-8As shown in the figure, an automatic sorting mechanism for anti-scattering cartons includes a feeding mechanism 1 for conveying small boxes, a box-topping mechanism 3 for receiving the small boxes conveyed by the feeding mechanism 1, a box-supporting mechanism 4 for receiving the row of small boxes lifted by the box-topping mechanism 3 and gathering them into a sheet, a flipping mechanism 6 for flipping the vertically stacked small boxes to horizontal, a front-pushing mechanism 2 and a rear-pushing mechanism 5 for transporting the small boxes in the box-supporting mechanism 4 to the flipping mechanism 6.

[0031] During operation, the small boxes enter the box-topping mechanism 3 from the feeding mechanism 1, are arranged in a row and then lifted upward, enter the box-supporting mechanism 4, are gathered into a sheet in the box-supporting mechanism 4, and are laterally pushed into the flipping mechanism 6 under the combined action of the front-pushing mechanism 2 and the rear-pushing mechanism 4. Finally, the flipping mechanism 6 flattens the vertically stacked small boxes to complete the sorting process.

[0032] The feeding mechanism 1 includes a frame 21, a conveyor belt 13 arranged on the frame 21, a clamping channel 12 arranged at the upper end of the frame 21, and an adjusting member 11 for adjusting the position of the clamping channel 12. At the end of the feeding mechanism 1, there is a pressing wheel 14 for flattening the small boxes and an adjusting member 15 for adjusting the position of the pressing wheel 14.

[0033] In use, the small boxes are guided by the clamping channel 12 and move from the conveyor belt 13 towards the single-box channel 31. After passing under the box-pressing assembly, they enter the single-box channel 31. Among them, both the clamping channel 12 and the pressing wheel 14 can be adjusted according to the shape of the small boxes.

[0034] The box-topping mechanism 3 includes a single-box channel 31, rollers 32 arranged on the side walls of the single-box channel 31, a full-material detection member 36 arranged at the end of the single-box channel 31, and a jacking assembly for jacking up the small boxes. The jacking assembly includes a jacking cylinder 33 arranged below the single-box channel 31 and a jacking member 34. At least two parallel cross bars 35 are arranged at the top end of the jacking member 34.

[0035] A single-box channel 31 is provided in the box-topping mechanism 3. This channel can only accommodate one small box to enter. Rollers 32 are arranged on both side walls of the channel, and the gap between the rollers 32 is the space for the cross bar 35 to rise and fall. Among them, the single-box channel 31 can be set to be adjustable. By setting an adjusting device, the width of the single-box channel 31 is adjusted, and at the same time, the width between two clamping plates 42 is also adjusted to adapt to small boxes of various specifications. The full-material detection member 36 is a trigger switch. When the single-box channel 31 is filled with materials, the full-material detection member 36 is triggered, and the jacking cylinder 33 operates to make the cross bar 35 jack up the row of small boxes.

[0036] The box holding mechanism 4 includes two outer frames 41 and two clamping plates 42 arranged above the single box channel 31. The outer frame 41 is arranged around the outer periphery of the clamping plate 42. A guide rod 43 and a slider cylinder 44 sliding on the surface of the guide rod 43 are arranged between the upper and lower frames of the outer frame 41. The slider cylinder 44 extends to the inner side of the clamping plate 42 through a cross arm. A long plate 45 is arranged at the end of the cross arm. A supporting plate 46 is hinged at the bottom end of the long plate 45. A limiting member 47 is arranged between the supporting plate 46 and the long plate 45.

[0037] The box supporting mechanism 4 is used to stack the small boxes vertically. When the top box mechanism 3 lifts up the small boxes, the small boxes push up the supporting plate 46. When the top box mechanism 3 descends, the supporting plate 46 drops to a horizontal level and is prevented from continuing to drop by the limiting member 47, thereby supporting the edge of the small box. The same is true when the top box mechanism 3 lifts up the next row of small boxes, until they are gathered into pieces. The small boxes are limited by the clamping plates 42 on both sides, and by the front push plates 25 and the rear push plates 54 on both sides, so that they are neatly arranged and will not scatter.

[0038] The forward pushing mechanism 2 includes a forward pushing plate 25 and a driving assembly. The frame of the forward pushing mechanism 2 is arranged above the feeding mechanism 1. The driving assembly includes a first motor 22 arranged on the frame, a toothed belt 23 driven by the first motor 22, and a sliding member 24 fixedly connected to the toothed belt 23. The bottom of the sliding member 24 is fixedly connected to the forward pushing plate 25.

[0039] The rear push mechanism 5 includes a rear push plate 54 and a stroke assembly 52. The rear push mechanism 5 is arranged at the rear end of the flip mechanism 6 away from the feeding direction. The stroke assembly 52 is arranged at the upper end of the base 51 and is driven by the second motor 53. The output end of the stroke assembly 52 is provided with a rear push plate 54 that passes through the gap between the rotating plate 63 and the fixed plate 61.

[0040] The left and right structures of the front push mechanism 2 and the rear push mechanism 5 are basically the same, and are used to support the two side edges of the small box. When the rear push plate 54 passes over the convex frame 67, the convex frame 67 is provided with a recess for the rear push plate 54 to pass through. The slider cylinder 44 in the box supporting mechanism 4 lifts the supporting plate 46 so that the supporting plate 46 is aligned with the bottom edge of the convex frame 67, and then the front push plate 25 and the rear push plate 54 push the small boxes in pieces into the flipping mechanism 6.

[0041] The flipping mechanism 6 includes a fixed plate 61 and a rotating plate 63, and a stroke cylinder 64 for driving the rotating plate 63 to be laid flat. The flipping mechanism 6 also includes a fixed rod 62, which is hinged to the rotating plate 63. The rotating plate 63 is provided with an L-shaped convex frame 67 for placing the small box on one side surface close to the fixed plate 61, and a clamping plate 66 for clamping the small box. The clamping plate 66 is driven by a clamping cylinder 65.

[0042] After entering the turning mechanism, the clamping cylinder 65 limits the upper end of the small box to prevent it from being scattered after being laid flat, and then the stroke cylinder 64 runs to lay the rotating plate 63 flat, completing the material sorting of the small box for convenient packing.

[0043] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
