Description
Technical Field
[0001] This invention relates to the field of logistics technology, and in particular to a workstation transfer device for cardboard box packaging. Background Technology
[0002] Cardboard packaging is an indispensable part of the commodity circulation process, widely used in food, pharmaceuticals, electronics, and many other fields. On the cardboard box production and packaging line, the workstation transfer equipment plays a crucial role, its main function being to smoothly and accurately transport cardboard boxes from one process to the next.
[0003] Existing paper box processing equipment typically consists of conveyor belts, simple robotic arms, or turntables. However, with the increasing demands for efficiency and precision in automated production, traditional equipment has gradually revealed the following technical problems in practical applications: Insufficient feeding positioning accuracy easily leads to cumulative errors: Traditional feeding lines often lack effective correction mechanisms. When cartons are slightly skewed or misaligned during high-speed transport, they directly enter subsequent transfer stages, causing them to jam, fall, or even be damaged during gripping or transfer. Existing positioning devices are mostly fixed and cannot adaptively adjust to the dimensions of cartons of different sizes, making it difficult to eliminate cumulative errors caused by long-distance transport.
[0004] Poor flow flexibility and inability to meet multi-position requirements: Most existing flow equipment can only achieve horizontal linear conveying or single-angle rotation, lacking the ability to adjust height in the vertical direction. In actual production, the joint heights of different processes are often inconsistent, or the cartons need to be flipped at a specific angle to accommodate subsequent processes. Traditional equipment cannot simultaneously adjust the cartons to a specified spatial angle and height, limiting its applicability and often requiring additional lifting or flipping mechanisms, resulting in complex equipment structures and high costs. Summary of the Invention
[0005] The purpose of this invention is to provide a workstation transfer device for paper box packaging, which solves the problem that the existing technology cannot achieve flexible adjustment of multiple angles and heights.
[0006] To achieve the above objectives, the present invention provides a workstation transfer device for cardboard box packaging, comprising a support assembly, a transfer assembly, and a conveying assembly. The support assembly includes a base, a support frame, a feeding line, and a positioning groove. The base and the support frame are fixedly connected and the base is located on one side of the support frame. The feeding line is rotatably mounted on the support frame. The transfer assembly includes a support rod, a rotating motor, a first rotating disk, and a second rotating disk. The support rod is fixed to the support frame, and the rotating motor is fixed to the top of the support rod. The first rotating disk has multiple enclosing plates for limiting the position of the cardboard box. The second rotating disk includes a second rotating disk body and multiple sliding plates. The second rotating disk body has multiple grooves and is rotatably disposed below the first rotating disk. The multiple sliding plates are slidably disposed in the multiple grooves for placing the cardboard box falling from the first rotating disk. The conveying assembly is disposed below the second rotating disk.
[0007] The support assembly also includes a correction plate, which is disposed on one side of the feeding line and is used to correct the position of the incoming paper box.
[0008] The calibration plate includes two calibration plate bodies, a screw, and a calibration motor. The two calibration plate bodies are slidably disposed on both sides of the feed line. The screw has two opposite threads and is threadedly connected to the two calibration plate bodies. The output end of the calibration motor is connected to the screw.
[0009] The first rotating disk has multiple positioning blocks, which are arranged corresponding to the enclosure plate. A positioning groove is slidably arranged on the support frame, and a support spring is installed between the positioning groove and the support frame. The positioning blocks cooperate with the positioning groove to correct the position of the enclosure plate.
[0010] The first rotating disk further includes multiple limiting rings, which are located between two adjacent enclosure plates to prevent the cardboard box from entering the position between the two adjacent enclosure plates.
[0011] The sliding plate includes a lifting cylinder, a return spring, and a sliding plate body. The lifting cylinder is fixed to the second rotating disk body, the sliding plate body is connected to the output end of the lifting cylinder, and the return spring is disposed between the lifting cylinder and the sliding plate body.
[0012] The second rotating disk also includes multiple closing plates, which are disposed in the groove and are used to close the groove before the cardboard box is sent out by the conveyor line.
[0013] The closing plate includes a closing plate body, a push block, a push rod, and a push cylinder. The closing plate body is rotatably mounted on the second rotating disk body, the push block is slidably mounted on the second rotating disk body, the push rod is rotatably connected to the closing plate body and the push block, and is located between the closing plate body and the push block, and the output end of the push cylinder is connected to the push block.
[0014] The rotating assembly further includes a guide plate, a rotating rod, and a locking nut. The rotating rod is rotatably mounted on the support frame. The guide plate is fixed on the rotating rod and located on one side of the feed line. The locking nut is threadedly connected to the rotating rod to lock the position of the rotating rod.
[0015] The conveying assembly includes a conveyor line, a lifting support plate, and a lifter. The lifting support plate is slidably mounted on the support frame and located below the second rotating disk body. The conveyor line is rotatably mounted on the lifting support plate, and the lifter is used to drive the lifting support plate to move up and down.
[0016] The present invention provides a stationary transfer device for paper box packaging, wherein the support component is the skeleton of the device, responsible for bearing all moving parts and ensuring the initial accuracy of feeding.
[0017] The base, serving as the foundation of the entire machine, is made of high-strength alloy steel to ensure the stability of the equipment under high-speed operation. The support frame is vertically fixed to one side of the base, forming a cantilever or portal structure to provide an installation interface for the components above.
[0018] The feeding line is mounted on a support frame, and an anti-slip conveyor belt can be laid on its surface to prevent the cartons from slipping. Positioning slots are located at the feeding line exit, their shape matching the bottom contour of the cartons to ensure the cartons are in the correct coordinate position before entering the transfer stage, eliminating accumulated errors.
[0019] The transfer unit smoothly and orderly transfers the cardboard boxes from the feeding position to the unloading position, and has the ability to process multiple stations in parallel.
[0020] Specifically, the first rotating disk is located on the upper layer and rotates synchronously with the motor. Its key feature is the presence of multiple enclosing plates. These enclosing plates are arranged radially or circumferentially, forming a temporary semi-enclosed space. When the cardboard box enters the enclosing plate area from the feeding line, the enclosing plates limit the cardboard box's perimeter, allowing the cardboard box to be rotated and moved.
[0021] The second rotating disk is located directly below the first rotating disk and is also driven by a drive mechanism. The body of the second rotating disk has multiple grooves corresponding to the positions of the enclosing plate of the first rotating disk. A sliding plate is embedded in these grooves and can slide vertically.
[0022] When the first rotating disk rotates to a preset angle, the cardboard box can fall down along the groove onto the sliding plate for support. The height of the sliding plate can be adjusted as needed, so that the cardboard box can be fed into a specified height and then sent out through the conveyor line. Thus, the present invention can rotate the cardboard box to a specified angle and a specified height, making it more widely applicable. Attached Figure Description

Detailed Implementation
[0032] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0033] Please see Figures 1-7This invention provides a workstation transfer device for cardboard box packaging, including a support assembly, a transfer assembly, and a conveying assembly. The support assembly includes a base 101, a support frame 102, a feeding line 103, and a positioning groove 105. The base 101 and the support frame 102 are fixedly connected and the base 101 is located on one side of the support frame 102. The feeding line 103 is rotatably mounted on the support frame 102. The transfer assembly includes a support rod 106, a rotating motor 107, a first rotating disk 108, and a second rotating disk 109. The support rod 106 is fixed to the support frame 102. The machine 107 is fixed to the top of the support rod 106. The first rotating disk 108 has a plurality of enclosure plates 110, which are used to limit the paper box. The second rotating disk 109 includes a second rotating disk body 111 and a plurality of sliding plates 112. The second rotating disk body 111 has a plurality of grooves. The second rotating disk body 111 is rotatably disposed below the first rotating disk 108. The plurality of sliding plates 112 are slidably disposed in the plurality of grooves for placing the paper box falling from the first rotating disk 108. The conveying assembly is disposed below the second rotating disk 109.
[0034] In this embodiment, the support component is the skeleton of the equipment, responsible for bearing all moving parts and ensuring the initial accuracy of feeding.
[0035] The base 101, serving as the foundation of the entire machine, is made of high-strength alloy steel to ensure the stability of the equipment under high-speed operation. The support frame 102 is vertically fixed to one side of the base 101, forming a cantilever or portal structure to provide an installation interface for the components above.
[0036] The feeding line 103 is rotatably mounted on the support frame 102. An anti-slip conveyor belt can be laid on the surface of the feeding line 103 to prevent the carton from slipping. The positioning groove 105 is opened at the outlet of the feeding line 103. Its shape matches the bottom contour of the carton to ensure that the carton is in an absolutely correct coordinate position before entering the transfer process, eliminating cumulative errors.
[0037] The transfer unit smoothly and orderly transfers the cardboard boxes from the feeding position to the unloading position, and has the ability to process multiple stations in parallel.
[0038] Specifically, the first rotating disk 108 is located on the upper layer and rotates synchronously with the motor. It is characterized by having multiple enclosing plates 110. These enclosing plates 110 are radially or circumferentially distributed, forming a temporary semi-enclosed space. When the cardboard box enters the area of the enclosing plates 110 from the feed line 103, the enclosing plates 110 limit the cardboard box around its perimeter, allowing the cardboard box to be rotated and moved.
[0039] The second rotating disk 109 is located directly below the first rotating disk 108 and is also driven by a drive mechanism. The body 111 of the second rotating disk has multiple grooves corresponding to the positions of the enclosing plate 110 of the first rotating disk 108. A sliding plate 112 is embedded in the grooves and can slide vertically.
[0040] When the first rotating disk 108 rotates to a preset angle, the paper box can fall down along the groove onto the sliding plate 112 for support. The height of the sliding plate 112 can be adjusted as needed so that the paper box can be fed into a specified height and then sent out through the conveyor line 130. Thus, the present invention can rotate the paper box to a specified angle and a specified height, making it more widely applicable.
[0041] The support assembly also includes a correction plate 104, which is disposed on one side of the feed line 103 and is used to correct the position of the incoming paper box.
[0042] The calibration plate 104 includes two calibration plate bodies 113, a screw 114, and a calibration motor 115. The two calibration plate bodies 113 are slidably disposed on both sides of the feed line 103. The screw 114 has two opposite threads and is threadedly connected to the two calibration plate bodies 113. The output end of the calibration motor 115 is connected to the screw 114.
[0043] The correction plate body 113 is slidably positioned on the left and right sides (or front and rear sides, depending on the direction of the carton's travel) of the feed line 103 conveying surface via linear guide rails or chute structures. This symmetrical layout ensures the balanced application of the correction force, preventing the carton from tilting or jamming during the correction process due to unilateral force.
[0044] The special feature of the screw 114 is its thread design—with the center of the screw 114 as the boundary, the two ends are machined with threads of opposite directions (i.e., one end is a left-hand thread and the other end is a right-hand thread). A high-precision calibration motor 115 (such as a stepper motor or servo motor) is also configured, whose output shaft is directly connected to one end of the aforementioned bidirectional threaded screw 114 via a coupling, providing the power source for the entire calibration operation.
[0045] When the control system detects that the carton has entered the feed line 103 or starts according to a preset program, the calibration motor 115 begins to rotate. The rotation of the motor drives the screw 114 to rotate. Since the threads at both ends of the screw 114 turn in opposite directions, when the screw 114 rotates, the two calibration plate bodies 113 threadedly connected to it will move in opposite directions (clamping / calibrating) or in opposite directions (releasing / resetting) along the axis of the screw 114. Regardless of the initial position of the two calibration plate bodies 113, as long as the screw 114 rotates, their displacement relative to the center of the screw 114 is always equal. This means that no matter what the initial offset of the carton is, the two calibration plates 104 can advance synchronously inward with the center line as a reference, ensuring that the carton is ultimately pushed accurately to the geometric center line of the feed line 103, rather than biased to one side.
[0046] The first rotating disk 108 has a plurality of positioning blocks 116, which are arranged corresponding to the enclosure plate 110. A second positioning groove 117 is slidably arranged on the support frame 102. A support spring 118 is installed between the second positioning groove 117 and the support frame 102. The positioning blocks 116 cooperate with the second positioning groove 117 to correct the position of the enclosure plate 110.
[0047] A positioning block 116 is rigidly connected to the bottom or side of each station of the first rotating disk 108 (i.e., the corresponding position of each enclosure plate 110). Correspondingly, a second positioning groove 117 is slidably provided on the stationary support frame 102.
[0048] The second positioning groove 117 is not rigidly fixed to the support frame 102, but is elastically connected to the support frame 102 via a support spring 118. This design constitutes a "floating guide mechanism". When the first rotating disk 108 rotates to a specific station (such as the feeding or unloading position) and is about to stop, the positioning block 116 on the disk body will insert into the second positioning groove 117 on the support frame 102. If there is a slight deviation in the stopping position of the rotating disk due to mechanical transmission clearance, the positioning block 116, guided by the inclined surface entering the second positioning groove 117, will push the second positioning groove 117 to make a slight displacement, compressing the support spring 118. Under the action of the spring's restoring force, the second positioning groove 117 will exert a reverse force on the positioning block 116, forcibly "pulling" the first rotating disk 108 back to the correct center position.
[0049] This combination of "hard contact + soft buffer" not only eliminates backlash errors in gear or motor transmissions and achieves high-precision repeatability, but also avoids noise and mechanical damage caused by rigid collisions.
[0050] The first rotating disk 108 also includes a plurality of limiting rings 119, which are located between two adjacent enclosure plates 110 to prevent the cardboard box from entering the position between the two adjacent enclosure plates 110.
[0051] On the first rotating disk 108, a raised limiting ring 119 is added between every two adjacent enclosure plates 110. The height of the limiting ring 119 is slightly higher than the effective height of the bottom surface or side wall of the enclosure plate 110, forming a physical barrier. The limiting ring 119 occupies the ineffective space between the enclosure plates 110. When the cardboard box falls from the feed line 103, even if lateral deviation occurs, it will first hit the side wall of the limiting ring 119, thus being blocked within the entrance range of the target enclosure plate 110 and unable to enter the adjacent station.
[0052] The sliding plate 112 includes a lifting cylinder 120, a return spring 121, and a sliding plate body 122. The lifting cylinder 120 is fixed to the second rotating disk body 111, and the sliding plate body 122 is connected to the output end of the lifting cylinder 120. The return spring 121 is disposed between the lifting cylinder 120 and the sliding plate body 122.
[0053] The lifting cylinder 120, as an active actuator, is vertically fixedly installed at the bottom of the groove or on the bracket of the second rotating disk body 111.
[0054] The sliding plate body 122 serves as the bearing surface that directly contacts the paper box, and its back is rigidly connected to the piston rod output end of the lifting cylinder 120.
[0055] The return spring 121, as a passive safety component, is sleeved or connected in parallel between the cylinder body of the lifting cylinder 120 and the sliding plate body 122 (or located at the limit position of the piston rod stroke). This allows the height of the sliding plate body 122 to be controlled by the lifting cylinder 120, making it more convenient to use. The return spring 121 is used to reset the sliding plate body 122.
[0056] The second rotating disk 109 also includes a plurality of closing plates, which are disposed in the groove and are used to close the groove before the paper box is sent out by the conveyor line 130.
[0057] The closing plate includes a closing plate body 123, a push block 124, a push rod 125, and a push cylinder 126. The closing plate body 123 is rotatably mounted on the second rotating disk body 111. The push block 124 is slidably mounted on the second rotating disk body 111. The push rod 125 is rotatably connected to the closing plate body 123 and the push block 124 and is located between the closing plate body 123 and the push block 124. The output end of the push cylinder 126 is connected to the push block 124.
[0058] Before the cardboard box is delivered by the conveyor line 130, the groove opening is automatically closed to form a temporary storage compartment; once the conveyor line 130 is ready, the groove is automatically opened to release the cardboard box.
[0059] The closing plate body 123 is rotatably mounted on the edge of the groove of the second rotating disk body 111 via a pin. Its shape matches the cross-section of the groove, and when closed, it can perfectly fill the groove opening to form a closed or semi-closed cavity, which can directly prevent the cardboard box from falling or sliding out, providing physical restraint.
[0060] The pusher block 124 is slidably disposed in the guide groove inside the second rotating disk body 111, and its movement trajectory is at a specific angle (usually perpendicular or inclined) to the rotation plane of the closing plate body 123. It can serve as an intermediate transmission component to convert the linear thrust of the cylinder into the displacement of the pushing rod.
[0061] One end of the push rod 125 is hinged (rotatably connected) to the back of the closing plate body 123, and the other end is hinged (rotatably connected) to the push block 124. It is located between the closing plate body 123 and the push block 124. Through the lever principle, the short-stroke linear motion of the push block 124 is converted into the large-angle rotational motion of the closing plate, ensuring tight closure.
[0062] The push cylinder 126 is fixedly mounted on the internal support of the second rotating disk body 111, and its output end (piston rod) is directly rigidly connected to the push block 124. The central control system issues commands based on the position of the rotating disk and the status of the conveyor line 130 to control the reciprocating motion of the push block 124.
[0063] The rotating assembly also includes a guide plate 127, a rotating rod 128, and a locking nut 129. The rotating rod 128 is rotatably mounted on the support frame 102. The guide plate 127 is fixed on the rotating rod 128 and located on one side of the feed line 103. The locking nut 129 is threadedly connected to the rotating rod 128 and is used to lock the position of the rotating rod 128.
[0064] To accommodate the feeding angle requirements of different sized cardboard boxes and to solve the problem of misalignment caused by installation errors, this invention integrates a finely adjustable rotating guide mechanism on the support frame 102. This mechanism consists of a rotating rod 128, a guide plate 127, and a locking device, realizing stepless adjustment and rigid locking of the feeding path.
[0065] The rotating rod 128 is a high-strength rotating shaft, which is rotatably mounted on the side wall or crossbeam of the support frame 102 via a bearing seat. Its axis is designed to be perpendicular to the ground, serving as the rotation center of the entire guiding mechanism.
[0066] The guide plate 127 is a piece of board with a specific curvature or angle, rigidly fixed to the middle or end of the rotating rod 128. Its position is precisely arranged on the side of the outlet of the feed line 103, forming the last physical barrier before the carton enters the first rotating disk 108.
[0067] The locking nut 129 is fitted onto the threaded section of the rotating rod 128, located on one side (or both sides) of the contact surface of the bearing housing or support frame 102.
[0068] When it is necessary to change the cardboard box specifications or correct the feeding trajectory, the operator only needs to loosen the locking nut 129 to release its axial clamping force on the rotating rod 128. At this time, the rotating rod 128 can rotate freely within the bearing. Manually or with the aid of tools, the rotating rod 128 is rotated, causing the guide plate 127 to swing around the axis. By changing the angle and distance between the guide plate 127 and the feeding line 103, the cutting angle and buffering force of the cardboard box sliding into the enclosure plate 110 can be precisely controlled to ensure that the cardboard box enters the limiting area in the best posture. After adjusting to the ideal position, the locking nut 129 is tightened again. The huge axial clamping force generated by the nut firmly "locks" the rotating rod 128 onto the support frame 102, using friction to prevent the equipment from shifting during high-speed vibration and ensuring the long-term stability of the guide angle.
[0069] The conveying assembly includes a conveyor line 130, a lifting support plate 131, and a lifter 132. The lifting support plate 131 is slidably disposed on the support frame 102 and located below the second rotating disk body 111. The conveyor line 130 is rotatably disposed on the lifting support plate 131. The lifter 132 is used to drive the lifting support plate 131 to move up and down.
[0070] To address the problems of traditional fixed conveyors being unable to adapt to cartons of varying heights and having large gaps between feeders that easily lead to drops and breakage, this invention designs an active lifting conveyor system. This system can dynamically adjust the feeding height according to the carton size and turnover rate, achieving seamless "zero drop" connection.
[0071] The lifting support plate 131 is a high-rigidity flat plate, which is slidably mounted on the column of the support frame 102 via linear guide rails or guide columns, located directly below the second rotating disk body 111. Its vertical movement freedom ensures the variability of its height.
[0072] The conveyor line 130 uses a conveyor device in the form of a belt, roller, or chain, which is rotatably mounted (i.e. installed and driven to rotate) on the upper surface of the lifting support plate 131. It rises and falls together with the support plate and is responsible for horizontally feeding the received cardboard boxes out.
[0073] The lifting device 132 is mounted at the bottom or top of the support frame 102, and is typically an electric push rod, a lead screw module, or a pneumatic cylinder. Its output end is connected to the lifting support plate 131 to provide precise vertical driving force.
[0074] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
