[0001] The invention relates to the technical field of cardboard palletizers, and more particularly to an automatic turning device of a cardboard palletizer. Background Art

[0002] The cardboard palletizer stacks the corrugated cardboard on the production line in a certain arrangement on the pallet to form a freight unit, which is convenient for adapting to mechanized, large-scale and high-speed modern logistics operations. The cardboard palletizer transfers and stacks the formed, printed, die-cut and bundled corrugated cardboard on the pallet, solving the problem of high labor intensity of manual palletizing. The cardboard palletizer is widely used for its high speed, intelligence, stability, and integration.

[0003] The cardboard palletizer needs to be designed together with the transmission unit and the corrugated cardboard processing unit in the entire production line. In order to ensure the neatness of the corrugated cardboard during palletizing, the production staff needs to manually turn over the cardboard pile on the transmission line from time to time to prevent the cardboard from bending naturally and affecting the flatness, and also make the stacked cardboard more layered and more reasonable. Manual intervention in this stage of work has the risk of mistakes, which will seriously affect the transportation and stacking of the current batch. Summary of the invention

[0008] Furthermore, when the cam transmission member moves to the rightmost and leftmost sides of the driving turntable, the matching baffle plate corresponds to the minimum swing angle and maximum swing angle; when the swing angle is minimum, the matching baffle plate is lower than the conveyor belt surface of the cardboard palletizer; when the swing angle is maximum, the angle between the matching baffle plate and the horizontal plane is greater than 90°.

[0009] Furthermore, the cam transmission member is bent downward as a whole, and the curvature of the cam transmission member is smooth.

DETAILED DESCRIPTION Example

[0018] The following is combined with Figure 1-4 The present invention is described in further detail.

[0019] An automatic turning device for a cardboard palletizer, such as Figure 1 As shown, it is arranged on the transmission line of the entire cardboard palletizer and is improved and optimized based on the frame of the cardboard palletizer.

[0020] like Figure 2 and Figure 3As shown, a driving turntable 10 is provided on the rising section of the frame of the cardboard palletizer. The driving turntable 10 is rotatably arranged on the frame through a driving shaft 11 that crosses the frame, and a special motor is also provided at the end of the driving shaft 11. A pair of fixed turntables are provided on the front end of the frame of the cardboard palletizer where the driving turntable 10 is arranged. The fixed turntables are fixed to the frame of the cardboard palletizer through docking holes around them and are symmetrically arranged on both sides. A special docking hole is provided at the center of the fixed disc 20, and docking holes are provided at the four corners of the outer side of the connecting rotating frame 30. The docking hole at the center of the fixed disc 20 is connected to the docking hole at the upper right corner of the outer side of the connecting rotating frame 30 through a pin shaft, and the connecting rotating frame 30 can rotate relative to the fixed disc 20. The connecting rotating frame 30 is linked to the driving turntable 10 through a cam fixing member. The cam rotating member is bent downward as a whole and has a smooth arc. A separate docking hole is provided on the circumference of the driving turntable 10, and docking holes are provided at both ends of the cam transmission member 40. The docking hole at the lower left corner of the connecting rotating frame 30, the docking holes at both ends of the cam transmission member 40, and the docking holes on the circumference of the driving turntable 10 are aligned one by one and connected by a pin shaft. In this way, the basic framework of the entire transmission system has been formed. The motor drives the driving turntable 10 through the driving shaft 11 and drives the driving turntable 10 to rotate. The driving turntable 10 is transmitted to the connecting rotating frame 30 through the cam transmission member 40 and drives the connecting rotating frame 30 to reciprocate and rotate and swing around the neutral line of the fixed disk 20. When the end of the cam transmission member 40 moves to the rightmost end of the driving turntable 10, the connecting rotating frame 30 takes the horizontal plane as the reference, and the swing angle of the connecting rotating frame 30 is the smallest; when the end of the cam transmission member 40 moves to the leftmost end of the driving turntable 10, the corresponding swing angle of the connecting rotating frame 30 exceeds the vertical area and continues to expand, and at this time the swing angle of the connecting rotating frame 30 is the largest.

[0021] like Figure 2 and Figure 4As shown, the mechanical structure of the swinging part is determined, and a direct acting structure of the cardboard pile 70 needs to be added to the key component of the connecting rotating frame 30. A plurality of baffle modules 50 arranged in an array are set on the connecting rotating frame 30 corresponding to the gaps between adjacent conveyor belts of the cardboard palletizer. The baffle module 50 includes a telescopic cylinder 51 and a dynamic baffle 52. The telescopic cylinder 51 is fixedly mounted on the connecting rotating frame 30, and the extension direction is consistent with the conveying direction of the cardboard pile 70. The telescopic cylinder 51 gives the entire structure a telescopic function. The dynamic baffle 52 docks with the telescopic end of the telescopic cylinder 51 and is an important motion transition piece. The telescopic cylinder 51 can drive the dynamic baffle 52 to extend or retract. A fixed slider 53 is fixedly set on the telescopic cylinder 51 or directly on the free position of the connecting rotating frame 30. A through sliding groove is set on the top of the fixed slider 53. A movable slide rail 54 parallel to the telescopic direction is set on the dynamic baffle 52. The movable slide rail 54 is slidably connected with the fixed slider 53, and the movable slide rail 54 is set lower than the dynamic baffle 52. This is to ensure that the dynamic baffle 52 is the component that directly contacts the cardboard pile 70. The movable slide rail 54 and the fixed slider 53 are set to guide and limit the telescopic movement of the dynamic baffle 52 to prevent deviation. At the same time, an angle reinforcement is added to the back of the end of the dynamic baffle 52 to strengthen the structure of the dynamic baffle 52 itself. A separate matching baffle 60 is set on the fixed end of the telescopic cylinder 51 or the connecting rotating frame 30 corresponding to the dynamic baffle 52. The matching baffle 60 is staggered from the dynamic baffle 52 and the two are vertical in space. The specific setting of the matching baffle 60 requires that when the swing angle of the connecting rotating frame 30 is the smallest, the end of the matching baffle 60 is lower than the surface of the conveyor belt of the cardboard stacker, does not affect the normal transmission of the cardboard pile 70 and is not completely horizontal, that is, at this time, the effective angle between the end of the matching baffle 60 and the horizontal plane is greater than 0°, and the cardboard pile 70 can be turned over faster and more effectively; when the swing angle of the connecting rotating frame 30 is the largest, the matching baffle 60 must also extend out of the gap between the adjacent conveyor belts, and the effective angle between the matching baffle 60 and the horizontal plane is greater than 90°. In order to smoothly make the end of the matching baffle 60 contact and clamp the cardboard pile 70, its end is designed to have a structure with a sinking slope surface, so that the initial contact is smoother and the collision is smaller. The matching baffle 60 and the dynamic baffle 52 cooperate to contact and clamp the cardboard pile 70. During the swinging process, the telescopic cylinder 51 is extended and retracted to drive the dynamic baffle 52 to extend or retract into the gap between the adjacent conveyor belts of the cardboard stacker.

[0022] The entire structure is controlled by an automated system, and the cardboard pile 70 is flipped in a regular or random manner according to the pre-programmed operation. The control mechanism interferes with the entire action by controlling the motor and telescopic cylinder 51 on the drive shaft 11. The drive motor ensures that the end of the cam transmission member 40 on the drive turntable 10 is located at its rightmost end under normal conditions. At this time, the matching baffle 60 and the dynamic baffle 52 are both below the surface of the conveyor belt, and there is no direct contact with the cardboard pile 70, which does not affect the normal transmission of the cardboard pile 70. When the intervention link preset by the program is triggered, the telescopic cylinder 51 responds quickly, driving the dynamic baffle 52 to extend out of the gap between the adjacent conveyor belts, and timely blocks the cardboard that needs to be flipped. At the same time, the motor on the drive shaft 11 responds, rotates the drive turntable 10, and makes the end of the cam transmission member 40 quickly rotate with it and move to the leftmost end of the drive turntable 10. The direct action structure of the entire cardboard pile 70 is connected to the synchronous rotation of the entire structure by the contact clamping of the cardboard pile 70 by the matching baffle 60 and the dynamic baffle 52. Under the action of the transmission system, the cardboard pile 70 flips over 90 degrees, completes the flip and naturally disengages from the matching baffle 60 and the dynamic baffle 52, falls onto the conveyor belt, continues to be transmitted, and is corrected in position with the help of subsequent regular components of the transmission line.

[0023] It should be noted that this specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
