Description

Technical Field

[0001] This invention relates to an egg roll packaging device, and more particularly to an automatic egg roll tray packaging device. Background Technology

[0002] After production, egg rolls need to be placed into trays for packaging. Currently, most manufacturers still use manual tray loading, where egg rolls are manually placed one by one into trays located on a conveyor belt. This manual loading method has problems such as high labor intensity, high labor costs, low production efficiency, and high egg roll breakage rate, and can no longer meet the needs of modern industrial automated production.

[0003] Therefore, it is necessary to develop and design an automatic egg roll tray packaging device to solve the problem of manual tray loading of egg rolls. Summary of the Invention

[0004] This invention addresses the problems of high labor intensity, high labor costs, low production efficiency, and high breakage rate associated with manual egg roll tray loading. It provides an automatic egg roll tray loading and packaging device that is simple in structure, easy to use, and can automatically load egg rolls into trays, thereby improving production efficiency and reducing labor costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic egg roll tray packaging device of the present invention includes a belt conveyor and a tray loading platform. The belt conveyor forms an inlet end and an outlet end at its two ends along the conveying direction. The tray loading platform is located outside the outlet end. The tray loading platform is provided with a tray-separating mechanism for intermittently dropping trays onto the tray loading platform, a tray-pushing mechanism for pushing trays containing egg rolls off the tray loading platform, and a tray-feeding mechanism for pulling trays dropped onto the tray loading platform forward to the front of the tray-pushing mechanism. The tray-feeding mechanism, tray-separating mechanism, and tray-pushing mechanism are sequentially arranged on the tray loading platform in the direction of the belt conveyor. A gripping mechanism for transferring egg rolls from the outlet end to the trays located in front of the tray-pushing mechanism is provided between the tray loading platform and the belt conveyor. The belt conveyor in this invention is existing technology, mainly used for conveying egg rolls. Egg rolls can be placed onto the conveyor belt from the feed end by a robotic arm. When the egg rolls are conveyed to the gripping mechanism, the gripping mechanism grabs the egg rolls and transfers them to a base tray located in front of the pushing mechanism. It releases the egg rolls, allowing them to fall into the base tray, and then resets. The pushing mechanism pushes the base tray containing the egg rolls out of the feeding platform and resets. The tray-separating mechanism causes the base trays to fall intermittently onto the feeding platform so that the feeding mechanism can push the base trays in front of the pushing mechanism. A guiding mechanism can also be provided between the tray-separating mechanism and the pushing mechanism. The guiding mechanism includes two opposing side baffles, with the gap between the side baffles forming a guiding channel. The opening of the guiding channel near the tray-separating mechanism is flared to prevent the base trays from tilting. This invention has a simple structure, is easy to use, and can automatically feed egg rolls into trays, improving production efficiency and reducing labor costs.

[0006] Preferably, the tray-separating mechanism includes a tray-dropping groove fixed to the tray-entry platform. The tray-dropping groove has a tray-separating channel for accommodating the tray. The lower part of the tray-separating channel has a blocking part to prevent the tray from falling. There is a gap between the tray at the bottom of the tray-separating channel and the tray-entry platform, which forms a tray-feeding channel. The tray-entry platform located below the tray-separating channel has a vacuum nozzle. After the bottom trays are stacked together, they are placed in the tray distribution channel. The blocking part is used to block the flange at the opening of the bottom tray (so that the bottom tray is suspended in the air), so that the bottom tray at the bottom is formed with the tray receiving platform, thus avoiding interference between the tray receiving mechanism and the bottom tray at the bottom of the tray distribution channel when the tray is moving forward. The vacuum nozzle is opened intermittently. When the vacuum nozzle is opened, the bottom tray at the bottom of the tray distribution channel is lifted by the suction of the vacuum nozzle, and the flange at the opening of the bottom tray can overcome the obstruction of the blocking part (causing deformation) and fall onto the tray receiving platform, thus realizing tray distribution. The other bottom trays fall under the action of gravity, and the flange at the opening of the bottom tray at the bottom of the tray distribution channel is blocked by the blocking part again.

[0007] Preferably, the tray includes two U-shaped trays, which are fixed to the tray platform with their openings facing each other. The gap between the U-shaped trays forms a tray distribution channel, and the blocking part is provided at the lower edge of both sides of the U-shaped tray.

[0008] Preferably, the blocking part is a locking tooth protruding from the edges of both sides of the U-shaped groove, and the upper tooth profile of the locking tooth is curved. The locking tooth structure is simple and can block and support the flange at the opening of the base; the upper tooth profile of the locking tooth is curved, so the base is not easy to get stuck when the vacuum nozzle is opened and can fall easily.

[0009] Preferably, the bottom support trough is provided with baffle rods on both sides facing the belt conveyor, and the U-shaped trough and baffle rods together form a support channel. The baffle rods limit the bottom support's movement towards the belt conveyor.

[0010] Preferably, the platform has two L-shaped mounting plates facing each other. The horizontal plate of each L-shaped mounting plate has a long connecting hole, and the horizontal plate is fastened to the platform by screws passing through the long connecting hole. The lower end of the U-shaped groove is fixedly connected to the vertical section of the L-shaped mounting plate. The drop trough has U-shaped seats on both sides facing the belt conveyor. Connecting plates are fixed to the outer ends of the U-shaped seats, and each connecting plate has a long connecting hole. The connecting plates are fastened to the platform by screws passing through the long connecting holes. The lower end of the support rod is fixed to the U-shaped seat. This structural design allows for adjustable spacing between the U-shaped grooves and between the support rods, making it suitable for bases of different sizes and improving the versatility of the invention.

[0011] Preferably, the material handling mechanism includes a rodless cylinder and a bracket. The bracket is fixed on the loading platform and the belt conveyor, respectively. The rodless cylinder is mounted on the bracket. Pen-shaped cylinders are provided on both sides of the moving slide of the rodless cylinder. An installation frame is fixed on the moving slide of the rodless cylinder. The bottom of the installation frame is provided with clamps and baffles at intervals along the conveying direction of the belt conveyor. The clamps and baffles are respectively hinged to the installation frame. The cylinder bodies of the pen-shaped cylinders on both sides of the installation frame are hinged to the installation frame. The piston rods of the pen-shaped cylinders are respectively hinged to the clamps and baffles. Elastic blocks are provided on the clamps and baffles. In this invention, the movement of the baffle can be adjusted according to the operation mode of the belt conveyor. When the conveyor belt of the belt conveyor is continuously conveying, the piston rod of the pen-shaped cylinder connected to the baffle extends, causing the baffle to flip downwards, and the pen-shaped cylinder connected to the baffle stops operating. The baffle remains fixed. When the egg roll on the conveyor belt of the belt conveyor is conveyed to the baffle, it can be blocked by the baffle. The piston rod of the pen-shaped cylinder connected to the clamp extends, causing the clamp to flip downwards and cooperate with the baffle to clamp the egg roll. The moving slide of the rodless cylinder moves horizontally, transporting the egg roll to the bottom tray located in front of the pushing mechanism. Then, the piston rod of the pen-shaped cylinder connected to the clamp retracts, the clamp flips upwards, thereby releasing the egg roll, and the egg roll falls directly to the bottom tray. When the conveyor belt of the belt conveyor is in intermittent conveying mode, the pen-shaped cylinders connecting the baffle and the clamping plate operate synchronously. When the egg rolls on the conveyor belt are conveyed to the lower part of the moving slide of the rodless cylinder, the piston rods of the pen-shaped cylinders connecting the baffle and the clamping plate extend simultaneously, causing the baffle and clamping plate to flip downwards to clamp the egg rolls. The moving slide of the rodless cylinder moves horizontally, transporting the egg rolls to the bottom tray located in front of the pushing mechanism. Then, the piston rods of the pen-shaped cylinders connecting the baffle and the clamping plate retract simultaneously, causing the baffle and clamping plate to flip upwards to release the egg rolls. The egg rolls then fall directly into the bottom tray, completing the placement process.

[0012] Preferably, the mounting frame is equipped with a pressing cylinder, and a pressing block is fixed on the piston rod of the pressing cylinder. The pressing block is located between the clamping plate and the baffle. When the feeding mechanism releases the egg roll, the pressing block is pressed down by the pressing cylinder to ensure that the egg roll can be fully placed in the tray and to prevent the egg roll from being placed incompletely and resting on the flip edge of the bottom tray.

[0013] Preferably, the pushing mechanism includes a pushing cylinder and an L-shaped push plate, wherein the pushing cylinder is fixed on the loading platform and the L-shaped push plate is fixed to the piston rod end of the pushing cylinder.

[0014] Preferably, the feeding mechanism includes a feeding cylinder and a U-shaped push plate, wherein the feeding cylinder is fixed on the feeding platform and the U-shaped push plate is fixed to the end of the piston rod of the feeding cylinder.

[0015] Therefore, the present invention has the following beneficial effects: through the cooperation between the belt conveyor, the tray loading platform, the tray pushing mechanism, the tray delivery mechanism and the tray separating mechanism, the structure is simple and easy to use, realizing automatic tray loading of egg rolls, which is conducive to improving production efficiency, reducing labor costs and meeting the needs of automated egg roll production.

The belt conveyor has an inlet end 3 and an outlet end 4 at its two ends along the conveying direction. The tray loading platform is located outside the outlet end. The tray loading platform is equipped with a tray-separating mechanism that causes trays to intermittently fall onto the platform, a pushing mechanism that pushes trays containing egg rolls 5 off the platform, and a tray-feeding mechanism that pulls trays that have fallen onto the platform forward to the front of the pushing mechanism. The tray-feeding mechanism, tray-separating mechanism, and pushing mechanism are sequentially arranged on the tray loading platform towards the belt conveyor. A connection is provided between the tray loading platform and the belt conveyor for rotating the egg rolls at the outlet end. The material-grabbing mechanism is moved to the bottom support located in front of the pushing mechanism; the material-dividing mechanism includes a dropping trough, which includes two U-shaped troughs 10. Two L-shaped mounting plates 12 are fixedly fixed to each other on the feeding platform. The horizontal plate of the L-shaped mounting plate has a long connecting hole 13. The horizontal plate of the L-shaped mounting plate is fastened to the feeding platform by screws 14 passing through the long connecting hole. The lower end of the U-shaped trough is fixedly connected to the vertical section of the L-shaped mounting plate. The openings of the two U-shaped troughs are opposite each other. The lower part of the edge of both sides of the U-shaped trough protrudes to form a blocking part 7. The blocking part is a tooth with a curved upper tooth profile. U-shaped seats 15 are fixed on both sides of the dropping trough facing the belt conveyor (e.g., Figure 2 As shown), connecting plates 16 are fixed to the outer sides of both ends of the U-shaped seat. Long connecting holes are opened on the connecting plates. The connecting plates and the support platform are fastened together by screws passing through the long connecting holes. A stop rod 11 is fixed to the inner side of the U-shaped seat. The U-shaped groove and the stop rod together form a support channel 6 (as shown). Figure 3 As shown), there is a gap between the bottom tray at the bottom of the tray distribution channel and the tray entry platform, which forms the tray delivery channel 8. A vacuum nozzle 9 is installed in the tray entry platform located below the tray distribution channel (as shown). Figure 4 (As shown); the material handling mechanism includes a rodless cylinder 17 and a support 18 (as shown). Figure 5 As shown), the brackets are fixed on the loading platform and the belt conveyor respectively. A rodless cylinder is mounted on the bracket. Pen-shaped cylinders 19 are provided on both sides of the moving slide of the rodless cylinder. A mounting frame 20 is fixed on the moving slide of the rodless cylinder. Clamping plates 21 and baffles 23 are spaced apart at the bottom of the mounting frame along the conveying direction of the belt conveyor. The clamping plates and baffles are hinged to the mounting frame. The cylinder bodies of the pen-shaped cylinders on both sides of the mounting frame are hinged to the mounting frame. The piston rods of the pen-shaped cylinders are hinged to the clamping plates and baffles respectively. Elastic blocks 22 are provided on the clamping plates and baffles. A pressing cylinder 24 is provided on the mounting frame. A pressing block 25 is fixed on the piston rod of the pressing cylinder, and the pressing block is located between the clamping plates and baffles. The pushing mechanism includes a pushing cylinder 26 and an L-shaped push plate 27 (as shown). Figure 6As shown), the pushing cylinder is fixed on the loading platform, and the L-shaped push plate is fixed on the piston rod end of the pushing cylinder; the feeding mechanism includes a feeding cylinder 28 and a U-shaped push plate 29. The feeding cylinder is fixed on the loading platform, and the U-shaped push plate is fixed on the piston rod end of the feeding cylinder; a guiding mechanism is also provided between the separating mechanism and the pushing mechanism. The guiding mechanism includes two side baffles 30 arranged opposite to each other. The gap between the side baffles forms a guiding channel 31. The opening of the guiding channel near the separating mechanism is set as a flared structure.

[0025] The operating principle of this invention is as follows: A robotic arm (not shown in the figure) grips the egg roll 32 onto the conveyor belt of a belt conveyor. The piston rod of the pen-shaped cylinder connecting the baffle extends, causing the baffle to flip downwards. The pen-shaped cylinder connecting the baffle stops operating, and the baffle remains fixed. When the egg roll on the conveyor belt reaches the baffle, it is blocked by the baffle (elastic block). The piston rod of the pen-shaped cylinder connecting the clamp extends, causing the clamp to flip downwards and engage with the baffle to clamp the egg roll. The sliding table of the rodless cylinder moves horizontally, transporting the egg roll to the base located in front of the pushing mechanism. Then, the piston rod of the pen-shaped cylinder connecting the clamp retracts, causing the clamp to flip upwards, thus releasing the egg roll, which then falls directly to the ground. In the base tray, the piston rod of the pressing cylinder drives the pressing block to press down and then reset, completing the egg roll placement. At the same time, the material gripping mechanism resets, and the pushing cylinder drives the L-shaped push plate to push out the egg roll with the base tray and then reset the L-shaped push plate. The vacuum nozzle opens, and the base tray at the bottom of the tray distribution channel is lifted by the suction of the vacuum nozzle. The flange at the opening of the base tray can overcome the obstruction of the caliper (causing deformation) and fall onto the tray placement platform to achieve tray placement. The other base trays fall under the action of gravity. The flange at the opening of the base tray at the bottom of the tray distribution channel is blocked again by the blocking part. The tray delivery cylinder drives the U-shaped push plate to push the base tray that has fallen onto the tray placement platform through the tray delivery channel and the guide channel to the front of the pushing mechanism and then reset.
