Description

Technical Field

[0001] The invention belongs to the technical field of weighing and palletizing, and in particular relates to automatic weighing and palletizing equipment. Background Art

[0002] Palletizer is a device that automatically stacks the delivered material bags, cartons or other packaged products into stacks according to the working method required by the process, and transports the stacked materials. It can stack multiple layers and then push them out, saving transportation space and making it easier for forklifts to transfer the stacked goods to warehouses for storage. With the continuous development of logistics, food and other industries, the batch size of goods is getting larger and larger. Palletizers are widely used in the stacking of cartons, plastic boxes, bottles, bags, barrels, box-shaped products and filled products.

[0003] Publication No. "CN215400958U" discloses "a palletizing device with a self-weighing function". By integrating a weighing mechanism into the palletizing device, weighing operations are performed while materials are palletizing, reducing the workload of manual operation and handling, and saving labor costs. The weighing sensors arranged at the four corners of the weighing mechanism make material weighing more accurate and improve the packaging quality of the product. The rollers arranged on the weighing mechanism make it more convenient to transport materials after palletizing. Two layers of baffles are added on both sides of the palletizing device. The lower layer is fixed and the upper layer is a cylinder-driven ejection movable type. The height of the baffles can be adjusted according to the requirements of the material packaging dimensions to meet the stacking and palletizing of various types of industrial products and prevent materials from tipping over due to excessive stacking during the palletizing process.

[0004] The above prior art still has the following disadvantages:

[0005] 1. The height of the baffle is adjusted by the cylinder. Since the extension length of the cylinder is fixed, the height of the baffle cannot be controlled, and the height of the baffle is easily too high. When one of the cylinders fails, the baffles on both sides cannot be adjusted synchronously, and the synchronous up and down movement of the baffles on both sides cannot be guaranteed, resulting in poor use effect.

[0006] 2. Only the height of the baffle can be adjusted to meet the needs of different stacking heights. It is not possible to flexibly adjust the spacing between the baffles on both sides according to actual usage to adapt to the stacking and palletizing of products of different widths;

[0007] 3. If there are multiple weighing sensors, if one of them fails, the weight of the product cannot be accurately measured, and the weighing data is prone to errors.

[0008] To this end, we designed an automatic weighing and palletizing equipment to solve the above problems. Summary of the invention

[0009] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0010] The present invention is an automatic weighing and palletizing device, including a fixed frame and a movable frame movably inserted on the right side of the fixed frame. Fixed baffles are fixed on the outer sides of the upper surfaces of the fixed frame and the movable frame. Movable baffles are movably arranged inside the fixed baffles. A U-shaped frame is fixed between the front and rear surfaces of the fixed frame. Screws are rotatably arranged on both the fixed frame and the movable frame. Internal thread grooves are formed inside the movable baffles. The upper parts of the screws pass through the fixed baffles and are in threaded cooperation with the internal thread grooves inside the movable baffles. Driven bevel gears are fixed at the lower ends of the screws. Driving bevel gears are meshed inside the driven bevel gears. A number of sliding grooves are formed inside the movable frame. A number of support rods are fixed inside the fixed frame and are in movable cooperation with the sliding grooves;

[0011] Through the meshing action of the driving bevel gear and the driven bevel gear, it is convenient to drive the screw to rotate. Under the threaded cooperation of the screw and the movable baffle, it is convenient to adjust the up and down movement of the movable baffle, thereby achieving the purpose of adjusting the height of the two side baffles. It solves the disadvantages that in the use process of the existing palletizing device with self-weighing function, the height of the baffle is adjusted by the cylinder. Since the extension length of the cylinder is fixed, it is impossible to control the height of the up and down movement of the baffle, effectively avoiding the phenomenon of too high baffle height. At the same time, it eliminates the disadvantage that if one of the cylinders fails, the synchronous adjustment of the two side baffles cannot be achieved, and the synchronous up and down movement of the two side baffles cannot be guaranteed.

[0012] An installation frame is arranged on the right side inside the U-shaped frame. A cross bar is fixed on the right surface of the installation frame. A sleeve is movably arranged outside the cross bar. A right fixed plate is rotatably installed on the outer surface of the sleeve through a bearing. The right fixed plate is fixed on the lower surface of the movable frame. The cross bar is of a hollow structure. An electric push rod is installed inside the installation frame. A top rod is fixed at the telescopic end of the electric push rod. The right end of the top rod is fixedly connected with the right inner surface of the sleeve. A rotating rod is fixed on the right end face of the left driving bevel gear. The right end of the sleeve is fixedly connected with the right driving bevel gear. A weighing mechanism is arranged below the U-shaped frame.

[0013] In the above structure, through the extension or contraction of the electric push rod, combined with the action of the ejector rod and the movable cooperation between the sleeve and the cross bar, it is convenient to drive the sleeve to move to the right or left. Under the fixed connection between the right fixed plate and the movable frame, and the movable cooperation between the movable frame and the fixed frame, the movable frame is driven to move away from or close to the fixed frame, achieving the purpose of adjusting the distance between the baffles on both sides, adapting to the stacking and palletizing of products of different sizes, and solving the drawback that in the existing palletizing device with self-weight function during use, only the height of the baffle can be adjusted to meet the use requirements of different stacking heights, and the distance between the baffles on both sides cannot be flexibly adjusted according to the actual use situation, improving the flexibility of the device and facilitating the use. Among them, under the action of the weighing mechanism, it is convenient to weigh the palletized products.

[0014] Further, the weighing mechanism includes a support plate arranged on the lower side of the U-shaped frame and a plurality of upright columns fixed on the support plate. A plurality of slots are formed on the lower surface of the U-shaped frame, and the slots correspond to the upright columns one by one and cooperate with each other. A base is arranged on the lower side of the support plate, and a weighing sensor is arranged on the upper surface of the base and cooperates with the lower surface of the support plate.

[0015] Further, a plurality of tooth grooves are formed inside the sleeve, and a plurality of teeth are fixed on the outer surface of the right side of the cross bar, and the teeth cooperate with the tooth grooves.

[0016] Further, two vertical plates are relatively fixed inside the U-shaped frame. A double-shaft motor is installed between the left and right vertical plates. The left output shaft of the double-shaft motor passes through the left vertical plate and is connected to the right end of the rotating rod. The right output shaft of the double-shaft motor passes through the right vertical plate and is connected to the left surface of the mounting frame. And the left end of the mounting frame is rotationally matched with the right vertical plate. A left fixed plate is rotatably arranged on the rotating rod, and the lower surface of the left fixed plate is fixed on the U-shaped frame.

[0017] Further, legs are fixed on the front and rear sides of the lower surfaces of the fixed frame and the movable frame. Two sleeves are relatively fixed on the left side of the upper surface of the support plate, and the left legs on both sides are respectively movably matched with the inner cavities of the two sleeves.

[0018] Further, a plurality of movable grooves are formed on the surface of the base, and T-shaped blocks are slidably arranged in the movable grooves. The upper ends of the T-shaped blocks are fixedly connected to the lower surface of the support plate, and springs are connected between the lower ends of the T-shaped blocks and the inner walls of the movable grooves.

[0019] Further, an installation groove is formed on the front surface of the base, and a display screen is installed in the installation groove. Grooves are formed on both the left and right sides of the installation groove, and a buzzer and a warning lamp are respectively installed in the left and right grooves.

[0020] Further, two lifting blocks are fixed on the left surface of the fixed frame and the right surface of the movable frame respectively.

[0021] Further, the movable baffle includes a horizontal plate and a plurality of vertical plates fixed to the lower surface of the horizontal plate. A plurality of avoidance grooves are formed on the mutually approaching surfaces of the left and right fixed baffles, which cooperate with the vertical plates. An internal thread groove is formed inside the middle vertical plate, and connecting plates are fixed to the lower sides between the middle vertical plate and the front and rear vertical plates.

[0022] The present invention has the following beneficial effects:

[0023] Through the meshing of the driving bevel gear and the driven bevel gear, the present invention facilitates driving the screw rod to rotate. Under the screw thread cooperation between the screw rod and the movable baffle, it is convenient to adjust the up and down movement of the movable baffle, thereby achieving the purpose of adjusting the heights of the two side baffles, solving the drawback that in the existing palletizing device with self-weight function during use, the height of the baffle is adjusted by the cylinder. Since the extending length of the cylinder is fixed, it is impossible to control the height of the up and down movement of the baffle, effectively avoiding the phenomenon that the baffle height is too high. At the same time, it eliminates the drawback that if one of the cylinders fails, the synchronous adjustment of the two side baffles cannot be achieved, and the synchronous up and down movement of the two side baffles cannot be guaranteed.

[0024] Meanwhile, through the extension or contraction of the electric push rod, combined with the action of the ejector rod, and the movable cooperation between the sleeve and the cross bar, it is convenient to drive the sleeve to move to the right or left. Under the fixed connection between the right fixing plate and the movable frame, and the movable cooperation between the movable frame and the fixed frame, the movable frame is driven to move away from or close to the fixed frame, achieving the purpose of adjusting the distance between the left and right side baffles, adapting to the stacking and palletizing of products of different sizes, solving the drawback that in the existing palletizing device with self-weight function during use, only the height of the baffle can be adjusted to meet the use of different stacking heights, and the distance between the two side baffles cannot be flexibly adjusted according to the actual use situation, improving the flexibility of the device and facilitating the use.

[0025] Among them, the mutual cooperation between the column and the slot, and the mutual cooperation between the two left legs and the inner cavity of the sleeve facilitate limiting the fixed frame, ensuring the stability of the device during the palletizing process. Combined with the weighing sensor, it is convenient to weigh the palletized products, without the need to use multiple weighing sensors, and solves the drawback that if one of the weighing sensors fails or malfunctions, the weight of the product cannot be accurately measured, and the weighing data is prone to errors.

[0026] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. Description of the Drawings

Under the threaded cooperation of the screw 6 and the adjustable baffle 4, it is convenient to adjust the up and down movement of the adjustable baffle 4, thereby achieving the purpose of adjusting the height of the two side baffles, solving the drawbacks that in the existing palletizing device with self-weighing function, when adjusting the height of the baffle through the cylinder, since the extension length of the cylinder is fixed, the height of the up and down movement of the baffle cannot be controlled, effectively avoiding the phenomenon that the baffle height is too high. At the same time, it eliminates the drawback that if one of the cylinders fails, the synchronous adjustment of the two side baffles cannot be achieved and the synchronous up and down movement of the two side baffles cannot be ensured.

[0043] On the right side inside the U-shaped frame 5, there is an installation frame 11. A cross bar 12 is fixed to the right surface of the installation frame 11. A sleeve 13 is movably arranged outside the cross bar 12. A right fixed plate 14 is rotatably installed on the outer surface of the sleeve 13 through a bearing.

A weighing mechanism is arranged below the U-shaped frame 5.

[0044] In the above structure, through the extension or contraction of the electric push rod 15, combined with the action of the push rod 16 and the movable cooperation between the sleeve 13 and the cross bar 12, it is convenient to drive the sleeve 13 to move to the right or left. Under the fixed connection between the right fixed plate 14 and the movable frame 2, and the movable cooperation between the movable frame 2 and the fixed frame 1, the movable frame 2 is driven to move away from or close to the fixed frame 1, achieving the purpose of adjusting the distance between the baffles on both sides, adapting to the stacking and palletizing of products of different sizes, solving the drawback that in the existing palletizing device with self-weighing function during use, only the height of the baffle can be adjusted to meet the use of different stacking heights, and the distance between the baffles on both sides cannot be flexibly adjusted according to the actual use situation, improving the flexibility of the device and facilitating the use. Among them, under the action of the weighing mechanism, it is convenient to weigh the palletized products.

[0045] The weighing mechanism includes a support plate 18 arranged below the U-shaped frame 5 and a number of upright columns 19 fixed to the support plate 18. A number of slots 17 are opened on the lower surface of the U-shaped frame 5. The slots 17 correspond to the upright columns 19 one by one and cooperate with each other. A base 20 is arranged below the support plate 18. A weighing sensor 21 is arranged on the upper surface of the base 20 and cooperates with the lower surface of the support plate 18.

[0046] A number of tooth grooves 22 are opened inside the sleeve 13. A number of teeth 23 are fixed to the right side of the outer surface of the cross bar 12. The teeth 23 cooperate with the tooth grooves 22.

[0047] Two vertical plates 24 are relatively fixed inside the U-shaped frame 5. A double-shaft motor 25 is installed between the left and right vertical plates 24. The left output shaft of the double-shaft motor 25 passes through the left vertical plate 24 and is connected to the right end of the rotating rod 10. The right output shaft of the double-shaft motor 25 passes through the right vertical plate 24 and is connected to the left surface of the installation frame 11. And the left end of the installation frame 11 is rotatably matched with the right vertical plate 24. A left fixed plate 34 is rotatably arranged on the rotating rod 10. The lower surface of the left fixed plate 34 is fixed to the U-shaped frame 5.

[0048] Legs 26 are fixedly attached to the front and rear sides of the lower surfaces of the fixed frame 1 and the movable frame 2. On the left side of the upper surface of the support plate 18, two sleeves 27 are relatively fixedly attached. The two left legs 26 are respectively movably engaged with the inner cavities of the two sleeves 27.

[0049] On the surface of the base 20, a number of movable grooves 28 are relatively formed. A T-shaped block 29 is slidably arranged in the movable groove 28. The upper end of the T-shaped block 29 is fixedly connected to the lower surface of the support plate 18. A spring 30 is connected between the lower end of the T-shaped block 29 and the inner wall of the movable groove 28.

[0050] On the front surface of the base 20, an installation groove is formed. A display screen 31 is installed in the installation groove. Grooves are formed on both the left and right sides of the installation groove. A buzzer 32 and a warning light 33 are respectively installed in the two left and right grooves.

[0051] Two lifting blocks 35 are fixedly attached to the left surface of the fixed frame 1 and the right surface of the movable frame 2.

[0052] The movable baffle 4 includes a horizontal plate and a number of vertical plates fixedly attached to the lower surface of the horizontal plate. On the mutually approaching surfaces of the two fixed baffles 3 on the left and right, a number of avoidance grooves are formed, which cooperate with the vertical plates. An internal thread groove is formed inside the middle vertical plate. Connecting plates are fixedly attached to the lower sides between the middle vertical plate and the front and rear vertical plates.

[0053] Embodiment:

[0054] First, use a forklift to adjust the U-shaped frame 5 to approach the column 19 and place the U-shaped frame 5 downward, so that the column 19 is inserted into the corresponding slot 17. At the same time, the two left legs 26 are driven to be inserted into the corresponding two sleeves 27.

[0055] During production, after the previous process completes material loading and packaging, according to the size of the material to be palletized, start the electric push rod 15 to extend. Under the action of the ejector rod 16, combined with the movable cooperation of the sleeve 13 and the cross bar 12, drive the sleeve 13 to move to the right. Under the fixed connection of the right fixing plate 14 and the movable frame 2, and the movable cooperation of the movable frame 2 and the fixed frame 1, further drive the movable frame 2 to move away from the fixed frame 1 until the distance between the two fixed baffles 3 on the left and right is adapted to the size of the material to be palletized, and then stop the extension of the electric push rod 15. This solves the drawback in the prior art that only the height of the baffle can be adjusted and the distance between the two side baffles cannot be flexibly adjusted according to the actual use situation, improves the flexibility of the device, and facilitates the use.

[0056] Both the front and rear sides inside the fixed frame 1 are provided with limit grooves. Limit blocks are fixed on the left sides of the front and rear surfaces of the movable frame 2 and are matched with the limit grooves. In combination with the cooperation between the support rod 9 and the chute, and considering that the extension length of the electric push rod 15 is limited, it effectively limits the movable frame 2 and prevents the movable frame 2 from detaching from the fixed frame 1. At the same time, with the cooperation between the limit block and the limit groove, and the cooperation between the support rod 9 and the chute, it effectively supports the movable frame 2 and ensures the stability of the bottom of the device during the palletizing process;

[0057] Then, the palletizing robot transfers the materials to this device. The fixed baffle 3 limits both sides of the palletized materials. When the palletizing reaches a certain height, the dual-axis motor 25 is started. The dual-axis motor 25 drives the rotating rod 10 and the mounting frame 11 to rotate simultaneously. Under the fixed connection between the mounting frame 11 and the cross bar 12, in combination with the rotational cooperation between the sleeve 13 and the right fixed plate 14, and the cooperation between the teeth 23 and the tooth grooves 22, it drives the sleeve 13 to rotate synchronously, and then drives the rotation of the left and right active bevel gears 8;

[0058] Under the meshing action of the active bevel gear 8 and the driven bevel gear 7, it drives the screw rod 6 to rotate. Under the threaded cooperation between the screw rod 6 and the movable baffle 4, it realizes the purpose of adjusting the upward movement of the movable baffle 4, and thus realizes the purpose of adjusting the height of both sides of the baffle, and is convenient for controlling the adjusted height. It solves the drawback in the prior art that when adjusting the height of the baffle through a cylinder, since the extension length of the cylinder is fixed, it is impossible to control the height of the up and down movement of the baffle, effectively avoiding the phenomenon of the baffle being too high. At the same time, it eliminates the drawback that if one of the cylinders fails, it is impossible to achieve the synchronous adjustment of both sides of the baffle and ensure the synchronous up and down movement of both sides of the baffle;

[0059] The inner side surface of the fixed baffle 3 and the inner side surface of the movable baffle 4 are on the same horizontal plane, which is convenient for palletizing the materials and avoids damaging the palletized materials due to the uneven inner side surface of the baffle;

[0060] During the palletizing process of the materials, as the materials are palletized between the two side baffles, the support plate 18 is pressed downward. Under the mutual cooperation of the T-shaped block 29 and the movable groove 28, the support plate 18 is stably pressed downward until it presses on the weighing sensor 21. The gravity is transmitted to the weighing sensor 21 through the support plate 18, and the weighing sensor 21 transmits the actual weight to the display screen 31. When the weight of the palletized materials reaches the set weight, a forklift or other lifting device is used to transfer the palletized materials, completing the weighing and palletizing of a batch of materials. When the materials exceed the pre-set weight, the buzzer 32 and the warning light 33 will give an alarm reminder simultaneously, facilitating the staff to make timely responses and handle the overweight situation. There is no need to set multiple weighing sensors 21, which solves the drawback that if any one of the multiple weighing sensors 21 fails or malfunctions, the product weight cannot be accurately measured.

[0061] When there is no material on the device, under the elastic action of the spring 30, the T-shaped block 29 is squeezed upward, thereby driving the support plate 18 away from the weighing sensor 21, making the support plate 18 not in contact with the weighing sensor 21. At this time, there is no gravity effect, and no data is displayed on the display screen 31, ensuring the accuracy of the weighing data during the palletizing process.

[0062] It should be further noted that the installation structure, connection method, or setting method of each component in the present invention are all common mechanical methods, and any implementation that can achieve its beneficial effects can be carried out. At the same time, the weighing sensor 21, the double-shaft motor 25, and the electric push rod 15 in the present invention are all purchased on the market, and those skilled in the art can install and use them according to the requirements.
