Description

Technical Field

[0001] This invention relates to the field of material transport equipment technology, and in particular to a material transport system for food processing. Background Technology

[0002] With the continuous development of industries such as logistics, food, and petrochemicals, the volume of goods is increasing. To save transportation space, goods need to be stacked neatly before transport. Since the quantity of goods is often large, manual stacking is too inefficient and cannot meet the stacking requirements in production. Therefore, automated feeding devices (such as palletizers and feeding robots) are playing an increasingly important role due to their high level of modernization.

[0003] To facilitate the transportation and storage of goods, it is often necessary to first neatly stack the goods on pallets before transferring the entire stack, thereby improving transportation efficiency and reducing storage costs. Existing palletizing devices mainly include automatic palletizers for tow boxes and automatic palletizers for cartons. However, during material transport, tilting and collisions are unavoidable, affecting the material's movement characteristics and resulting in poor continuity between material handling and clamping. Furthermore, the fixed gripper mechanisms can only handle goods of specific sizes, and the gripping method is not secure, easily leading to goods falling off. Moreover, the stacks of goods stacked by the palletizer are difficult to transport and transfer, making transshipment inconvenient. Therefore, designing a highly automated, safe, and efficient feeding system is essential. Summary of the Invention

[0004] To address the shortcomings in the aforementioned background technology, this invention proposes a material transportation system for food processing, which solves the problem of poor material transportation efficiency in the prior art.

[0005] The technical solution of the present invention is implemented as follows: a material transportation system for food processing includes a material handling device, an automatic clamping device, and a palletizing and conveying device. The automatic clamping device is located between the material handling device and the palletizing and conveying device and corresponds to the material handling device and the palletizing and conveying device respectively.

[0006] The palletizing and conveying device includes a movable support and a conveying mechanism. The conveying mechanism is located at the lower part of the movable support and passes through the movable support. A blocking and positioning mechanism and a lifting mechanism are symmetrically arranged on the side walls on both sides of the movable support. The lifting mechanism is located above the blocking and positioning mechanism. A baffle is provided on the movable support.

[0007] The conveying mechanism includes a conveyor frame, conveyor belts on both sides of the conveyor frame, magnetic seats on the conveyor belts, and support seats magnetically attracted to the magnetic seats. The support seats correspond to the stop fixing mechanism, and a support cylinder is provided at the lower part of the support seats.

[0008] The stop positioning mechanism includes a U-shaped seat fixed on a movable bracket. A rotating shaft is provided inside the U-shaped seat, and a swing arm bushing is rotatably mounted on the rotating shaft. One end of the swing arm bushing is connected to the drive device, and the other end corresponds to the support seat of the conveying mechanism. The swing arm bushing is provided with a connecting arm and a positioning arm. The connecting arm is connected to a swing cylinder set on the U-shaped seat through a connecting rod, and the positioning arm corresponds to the support seat of the conveying mechanism.

[0009] The lifting mechanism includes a fixed beam fixed on a movable support, with hinge seats symmetrically arranged on the fixed beam. Arc arms are hinged to the hinge seats and connected by a first connecting rod. The first connecting rod is connected to a drive cylinder arranged on the fixed beam. The free end of the arc arm is provided with a reinforcing arm. The drive cylinder is located on the midline of the line connecting the two hinge seats and is located above the hinge seats.

[0010] The gripper mechanism includes a rotating frame with a sliding support seat. The sliding support seat has a front moving gripper assembly and a rear flip-top cover assembly. The rear flip-top cover assembly corresponds to the front moving gripper assembly, and an upper pressure plate is provided between the rear flip-top cover assembly and the front moving gripper assembly. The front moving gripper assembly includes a connecting frame that is slidably connected to a slide rail on the sliding support seat. The sliding support seat has a telescopic cylinder, the telescopic end of which is connected to the connecting frame. The lower part of the connecting frame has claw teeth. The upper pressure plate is connected to the connecting frame via a vertical cylinder and is located between the claw teeth and the connecting frame.

[0011] The rear flip-up cover assembly includes a vertical plate mounted on a sliding support base, a driving component on the vertical plate, a swing shaft rotatably mounted on the sliding support base, the driving component being connected to the swing shaft, and a rear cover plate mounted on the swing shaft; the driving component is a small swing cylinder, which is connected to the swing shaft via a connecting crank arm; the rotating frame includes a rotary motor connected to a robotic arm, a rotary disk at the output end of the rotary motor, and the sliding support base being connected to the rotary disk.

[0012] The guide rail mechanism includes a support rail with a position switch on it. The bottom rotating mechanism is mounted on the support rail via a walking mechanism. The bottom rotating mechanism includes a support base with wheels on it. The wheels cooperate with the support rail. A large turntable is mounted on the support base and connected to the main drive. The robotic arm is mounted on the large turntable.

[0013] The material handling device includes a segmented support frame with a roller conveyor belt connected to a drive device mounted on a transmission support frame. The segmented support frame also includes a straightening mechanism and a guiding mechanism, and a buffer mechanism at each end of the segmented support frame. The segmented support frame includes a front support frame and a rear support frame of equal length and height, which are hinged together. The buffer mechanism includes an independent frame with a groove seat containing several rollers.

[0014] The straightening mechanism includes a first bracket fixed on a segmented support, a wheel seat on the first bracket, the wheel seat being connected to the first bracket by adjusting bolts, and a straightening wheel rotatably mounted on the wheel seat, the rotation direction of the straightening wheel corresponding to the movement direction of the roller conveyor belt; the guiding mechanism includes several second brackets fixed on the segmented support, guide plates hinged to the second brackets, and adjacent guide plates being hinged by a hinge mechanism; the hinge mechanism includes a sliding rod slidably disposed at one end of the guide plate, and a buckle at the other end of the guide plate cooperating with the sliding rod on the adjacent guide plate.

[0015] This invention's palletizing and conveying device positions the pallet of goods on the conveying mechanism using a stop-fixing positioning mechanism, and then lifts and removes the positioned pallet from the conveying mechanism using a lifting mechanism, achieving flexible and efficient transfer of the pallet. The magnetic seat on the conveyor belt is magnetically attracted and fixed to the support seat, ensuring stable transport of the support seat and enabling the lifting mechanism to quickly and easily lift it. The stop-fixing positioning mechanism and the lifting mechanism work together to achieve rapid and stable detachment of the support seat from the conveying mechanism, improving transfer efficiency. The segmented support structure of this invention's material handling device uses front and rear supports of equal length and height, allowing for both long-distance and short-distance material transport, offering flexibility. The straightening and guiding mechanisms are used to transport materials on the roller conveyor belt forward in the correct posture. The buffer mechanism can exist independently of the segmented support structure, temporarily storing materials when the transport volume is excessive, preventing material accumulation. The flexible design of the straightening and guiding mechanisms achieves minimal friction and flexible guidance of the materials, preventing tilting during transport and ensuring transport accuracy. The automatic clamping device features a front-moving gripper assembly that can move back and forth relative to the rear-tilting cover assembly, while the rear-tilting cover assembly can rotate up and down relative to the sliding support. The rear-tilting cover assembly works in conjunction with the front-moving gripper assembly to clamp different materials, ensuring stable material handling and transport, and improving material transport efficiency. This invention boasts an ingenious structural design, achieving efficient, safe, and automated material handling, feeding, and palletizing, thus improving overall feeding efficiency and possessing significant market and promotional value.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1As shown in Embodiment 1, a material transport system for food processing includes a material handling device 1, an automatic clamping device 2, and a palletizing and conveying device 3. The automatic clamping device 2 is located between the material handling device 1 and the palletizing and conveying device 3 and corresponds to both devices. Specifically, the material handling device transports materials to the clamping range of the automatic clamping device, which then clamps the materials and places them at the palletizing and conveying device. The palletizing and conveying device then transports the palletized materials out as a whole, improving transport efficiency. The automatic clamping device 2 includes a guide rail mechanism 21, through which the automatic clamping device changes position. A bottom rotating mechanism 22 is provided on the guide rail mechanism 21, and a robotic arm 23 is provided on the bottom rotating mechanism 22. The robotic arm rotates under the action of the bottom rotating mechanism, enabling flexible steering. A gripper mechanism 24 is provided at the free end of the robotic arm 23, which is used to clamp materials from the material handling device.

[0030] Furthermore, such as Figure 8 As shown, the palletizing and conveying device 3 includes a movable support 301 and a conveying mechanism 302. The movable support 301 is a support frame with wheels. The conveying mechanism 302 is located below the movable support 301 and passes through it, meaning the movable support spans across the conveying mechanism and works with it to transfer the pallet of goods from the conveying mechanism. A blocking and positioning mechanism 303 and a lifting mechanism 304 are symmetrically arranged on the side walls of both sides of the movable support 301. The lifting mechanism 304 is located above the blocking and positioning mechanism 303. The blocking and positioning mechanism is used to position the pallet of goods on the conveying mechanism, and then the lifting mechanism is used to lift and move the positioned pallet of goods away from the conveying mechanism. To ensure the stability of the pallet of goods, a baffle 305 is provided on the movable support 301 to prevent goods from slipping.

[0031] Furthermore, such as Figure 9 As shown, the conveying mechanism 302 includes a conveyor frame 302-1, which adopts a frame body that cooperates with the movable support. Conveyor belts 302-2 are provided on both sides of the conveyor frame 302-1, and the two conveyor belts drive synchronously to stably transport the stack of goods forward. Magnetic seats 302-3 are provided on the conveyor belts 302-2, and support seats 302-4 are magnetically attracted to the magnetic seats 302-3. The support seats and magnetic seats are fixed together by magnetic attraction. The support seats 302-4 correspond to the stop and positioning mechanism 303. The support seats do not interfere with the movable support and can ensure that the stop and positioning mechanism can contact and position the support seats. A support cylinder 303-5 is provided at the lower part of the support seat 302-4. Rollers can also be provided at the bottom of the support cylinder to support the support seat, acting as outriggers.

[0032] Furthermore, such as Figure 10As shown, the stop and fixation mechanism 303 includes a U-shaped seat 303-1 fixed on a movable support 301. The openings of the U-shaped seat 303-1 are arranged opposite each other. Two vertically arranged rotating shafts 303-3 are provided inside the U-shaped seat 303-1. A swing arm sleeve 303-2 is rotatably mounted on the rotating shafts 303-3, i.e., the swing arm sleeve is rotatably connected to the rotating shafts 303-3 via bearings. One end of the swing arm sleeve 303-2 is connected to the drive device, and the other end corresponds to the support seat 302-4 of the conveying mechanism 302. When the support seat moves between the stop and fixation mechanisms, the laser sensor on the swing arm sleeve transmits a signal to the controller. The controller controls the conveyor belt to stop moving, and the drive device drives the swing arm sleeve to rotate, causing the swing arm on the swing arm sleeve to contact and fix the support seat. Then, the lifting mechanism lifts the support seat and the stack of goods away from the conveyor belt, achieving transfer under the action of the movable support.

[0033] Specifically, the swing arm bushing 303-2 is provided with an integrally cast connecting arm 303-4 and a positioning arm 303-5. The connecting arm 303-4 is connected to the swing cylinder 303-6 set on the U-shaped seat 303-1 through a connecting rod. The swing cylinder drives the two swing arm bushings to rotate synchronously through the connecting rod. The positioning arm 303-5 corresponds to the support seat 302-4 of the transmission mechanism 302. During the rotation of the two swing arm bushings by the swing cylinder through the connecting rod, the positioning arm can contact the support seat, which plays a role in rapid positioning.

[0034] Furthermore, such as Figure 11 As shown, the lifting mechanism 304 includes a fixed beam 304-1 fixed on a movable support 301. Symmetrically arranged hinge seats 304-2 are mounted on the fixed beam 304-1. Arc-shaped arms 304-3 are hinged to the hinge seats 304-2, and the arc-shaped arms can rotate around the hinge point. The two arc-shaped arms 304-3 are connected by a first connecting rod 304-4. The first connecting rod 304-4 is connected to a drive cylinder 304-5 mounted on the fixed beam 304-1. The drive cylinder 304-5 is located on the midline of the line connecting the two hinge seats 304-2 and is positioned above the hinge seats 304-2. Under the action of the drive cylinder, the two arc-shaped arms rotate synchronously. To ensure stable contact with the support seat, a reinforcing arm 304-6 is provided at the free end of the arc-shaped arm 304-3. After the positioning mechanism positions the support seat, the support cylinder 303-5 lifts the support seat, separating it from the magnetic seat. Then, the cylinder extends, the reinforcing arm inserts into the support seat and lifts it a certain distance. Finally, the support seat and the stack of goods are transferred out by the moving bracket.

[0035] Example 2, as Figure 3As shown, a material transport system for food processing includes a gripper mechanism 24 comprising a rotating frame 24-1, which includes a rotary motor 24-1-1 connected to a robotic arm. The output end of the rotary motor 24-1-1 is provided with a turntable 24-1-2, and a sliding support 24-2 is connected to the turntable 24-1-2. Under the action of the rotary motor, the turntable rotates, driving the sliding support to rotate, thereby realizing the adjustment of the gripping direction or the direction of the material below. A sliding support seat 24-2 is provided on the rotating frame 24-1, which is connected to the turntable 24-1-2. The sliding support seat 24-2 is equipped with a front moving gripper assembly 24-3 and a rear tilting cover assembly 24-4. The rear tilting cover assembly 24-4 corresponds to the front moving gripper assembly 24-3; that is, the front moving gripper assembly can move back and forth relative to the rear tilting cover assembly, and the rear tilting cover assembly can tilt up and down relative to the sliding support seat. The rear tilting cover assembly 24-4 and the front moving gripper assembly 24-3 work together to grip materials. An upper pressure plate 24-5 is provided between the rear tilting cover assembly 24-4 and the front moving gripper assembly 24-3. The upper pressure plate presses down and clamps the material between the rear tilting cover assembly 24-4 and the front moving gripper assembly 24-3, ensuring the stability of material gripping and transportation.

[0036] Furthermore, the front moving gripper assembly 24-3 includes a connecting frame 24-3-1, which is slidably connected to a slide rail 24-6 mounted on a sliding support 24-2. A telescopic cylinder 24-7 is mounted on the sliding support 24-2, with its telescopic end connected to the connecting frame 24-3-1. Under the telescopic action of the cylinder, the connecting frame 24-3-1 moves along the slide rail 24-6, thereby realizing the movement of the front moving gripper assembly relative to the rear flip-up cover assembly, and determining whether the front moving gripper assembly is gripping. The lower part of the connecting frame 24-3-1 is provided with claw teeth 24-3-2, which are L-shaped teeth arranged in a row. The upper pressure plate is located above the row of L-shaped teeth, and the L-shaped teeth provide a pressing fulcrum for the upper pressure plate, keeping the material between them stable. Preferably, the upper pressure plate 24-5 is connected to the connecting frame 24-3-1 via a vertical cylinder 24-8, and the upper pressure plate 24-5 is located between the claw teeth 24-3-2 and the connecting frame 24-3-1. Under the action of the vertical cylinder, the upper pressure plate moves up and down, thereby controlling whether the material on the claw teeth is pressed, which facilitates operation.

[0037] Furthermore, the rear flip-top cover assembly 24-4 includes a vertical plate 24-4-1 fixedly mounted on the sliding support 24-2. The vertical plate 24-4-1 is provided with a driving component 24-4-2. The sliding support 24-2 is rotatably mounted with a swing shaft 24-4-3. The axis of the swing shaft is perpendicular to the direction of the slide rail. The driving component 24-4-2 is connected to the swing shaft 24-4-3, driving the swing shaft to rotate. The swing shaft 24-4-3 is provided with a rear cover plate 24-4-4. The rear cover plate is fixedly connected to the swing shaft and swings with the swing shaft, thereby realizing the back-and-forth swinging relative to the forward moving gripper assembly, blocking the material and effectively preventing the material from falling.

[0038] Preferably, the driving component 24-4-2 is a small swing cylinder, which is connected to the swing shaft 24-4-3 via a connecting crank arm 24-4-5. The small swing cylinder is fixed to the upright plate, and its extension and retraction drive the swing shaft to rotate via the connecting crank arm. When gripping materials, the piston of the small swing cylinder retracts, flipping up the rear cover plate to facilitate material gripping; when gripping materials, the piston of the small swing cylinder extends, lowering the rear cover plate to secure the materials and ensure stable and safe transportation.

[0039] The other structures are the same as in Example 1.

[0040] like Figure 2 As shown in Embodiment 3, an automatic feeding device based on a robot is described. The guide rail mechanism 21 includes a support rail 21-1, which can be set on the ground or other workbench. A bottom rotating mechanism 22 is mounted on the support rail 21-1 via a walking mechanism. A position switch is provided on the support rail 21-1, and the position switch is connected to a backend controller. When the bottom rotating mechanism moves to a specific position, the position switch transmits a signal to the backend controller, which then controls the walking mechanism of the bottom rotating mechanism to stop moving, thus achieving automatic adjustment. The bottom rotating mechanism 22 includes a support base 22-1, on which walking wheels are provided. The walking wheels cooperate with the support rail 21-1, and under the action of a drive device, the walking wheels drive the support base to move along the support rail. A large turntable 22-2 and a main drive 22-3 are connected to the support base 22-1. The robotic arm 23 is mounted on the large turntable 22-2. Under the action of the main drive, the large turntable drives the robotic arm to rotate, thereby enabling the robotic arm to drive the gripper mechanism to rotate, facilitating the picking and placing of materials.

[0041] Furthermore, such as Figure 4 , 5As shown, the material handling device 1 includes a segmented support 101, on which a roller conveyor belt 102 is mounted. The roller conveyor belt 102 is connected to a drive device 103 mounted on the transmission support 101. The drive device can be an electric motor or a hydraulic motor. The drive device drives the roller conveyor belt to rotate, transporting the material forward. The segmented support 101 includes a front support 101-1 and a rear support 101-2 of equal length and height, which are hinged together by a pin. When the transport path is long, the front support 101-1 and the rear support 101-2 are connected in series to ensure the longest possible transport path. When the transport path is short and the transport volume is large, the front support 101-1 and the rear support 101-2 are connected in parallel to form two conveyor belts, improving transport efficiency. The segmented support 101 is equipped with a correction mechanism 104 and a guiding mechanism 105, and a buffer mechanism 106 is provided at the end of the segmented support 101. The straightening mechanism 104 and the guiding mechanism 105 are used to transport the material on the roller conveyor belt 102 forward in the correct posture. The buffer mechanism and the segmented support can exist independently and are used to temporarily store materials when the material transport volume is too large.

[0042] Furthermore, such as Figure 6 As shown, the straightening mechanism 104 includes a first bracket 104-1 fixed on a segmented bracket 101. The first bracket can be arranged on both sides of the segmented bracket. A wheel seat 104-2 is provided on the first bracket 104-1. The wheel seat 104-2 is connected to the first bracket 104-1 by an adjusting bolt 104-3. The distance of the wheel seat extending out of the first bracket is adjusted by the adjusting bolt, which is used to adjust the position of the material on the roller conveyor belt laterally. A straightening wheel 104-4 is rotatably provided on the wheel seat 104-2. The rotation direction of the straightening wheel 104-4 corresponds to the movement direction of the roller conveyor belt 102. That is, the straightening wheel 104-4 makes rolling contact with the material during the contact process, reducing the friction between the straightening mechanism and the material during the straightening process, so as not to affect the material transportation.

[0043] The other structures are the same as in Example 2.

[0044] Implementation 4, such as Figure 7 As shown, a material handling device for food production includes a guiding mechanism 105 comprising a plurality of second supports 105-1 fixed on a segmented support 101. The second supports can be arranged on either side or one side of the segmented support, and the number can be 1 to 4. Guide plates 105-2 are hinged to the second supports 105-1. The guide plates can be connected to the second supports via studs, and their extension length is adjustable. Adjacent guide plates 105-2 are hinged together via a hinge mechanism to achieve flexible guiding.

[0045] Furthermore, the hinge mechanism includes a slide rod 105-3 slidably disposed at one end of the guide plate 105-2, that is, the guide plate is provided with a slide rail, and the slide rod can slide in the slide rail. The other end of the guide plate 105-2 is provided with a buckle 105-4 that cooperates with the slide rod 105-3 on the adjacent guide plate 105-2. The buckle can be locked onto the slide rod and can rotate around the slide rod, so as to realize the overall guiding flexibility of the guide mechanism.

[0046] Furthermore, the buffer mechanism 106 includes an independent frame 106-1, with wheels at the bottom for free movement. The independent frame 106-1 has slots 106-2, the number of which can be set as needed and are arranged in parallel. Each slot 106-2 contains several rollers 106-3, which roll in contact with the material to reduce friction. When too much material is transported, it is temporarily stored on the buffer mechanism to prevent material accumulation.

[0047] The other structures are the same as in Example 3.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
