Description

Technical Field

[0001] The embodiments of this utility model relate to the field of feeding equipment technology, specifically to a dual-station feeding device and a parallel palletizing production line. Background Technology

[0002] With the continuous growth of market demand for products and the increasing level of production automation, industrial palletizing technology is also constantly innovating to meet the needs of large-scale, high-efficiency, and high-precision production. Various types of palletizing equipment are emerging and are widely used in many industries such as food, chemicals, and logistics.

[0003] In actual palletizing operations, to fully utilize warehouse space and ensure palletizing stability, product palletizing methods are often quite complex, with each pallet having more than one row of products. Taking the case where each pallet has two rows of products as an example, during the palletizing process, the products need to be pushed row by row to the designated position to form a complete pallet. However, most current palletizing equipment uses a single production line, which can only output one row of products at a time, resulting in the need for two pushes to complete the stacking of one pallet.

[0004] On the one hand, the two push operations increase the time required for palletizing, resulting in low palletizing efficiency and an inability to meet the ever-increasing production speed requirements. On the other hand, the frequent push operations significantly increase the usage frequency of various equipment components, accelerating equipment wear and tear and increasing maintenance costs.

[0005] Therefore, for situations where each product stack has multiple rows of products, how to improve palletizing efficiency and reduce equipment wear and tear has become an important problem that urgently needs to be solved in the current industrial palletizing field. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this utility model provide a dual-station feeding device and a parallel palletizing production line, which solves the technical problem in the related technology that when there are two rows of products in each product stack, it takes two pushes to complete the stacking of one product stack, resulting in low palletizing efficiency.

[0007] According to one aspect, at least one embodiment of the present invention provides a dual-station feeding device, including a frame, a feeding conveyor, a distributing conveyor, a gantry frame, and a distributing plate. The feeding conveyor and the distributing conveyor are sequentially arranged on the frame. The output end of the feeding conveyor faces the middle of the distributing conveyor and is used to transport products to the middle of the distributing conveyor. The gantry frame is arranged on the frame and located above the distributing conveyor. The distributing plate is slidably arranged relative to the gantry frame. The distributing plate is capable of pushing products located in the middle of the distributing conveyor to either side, so that the products are subsequently transported in two rows.

[0008] For example, the dual-station feeding device provided in at least one embodiment of this utility model further includes:

[0009] The gantry frame is equipped with a pair of synchronous pulleys that rotate in rotation. A transmission belt is fitted onto the two synchronous pulleys. A sliding frame is provided on the top of the material distribution plate. The sliding frame is mounted on the transmission belt, which is used to drive the material distribution plate to slide.

[0010] For example, the dual-station feeding device provided in at least one embodiment of this utility model further includes:

[0011] A drive shaft is rotatably mounted on the gantry frame. Two sets of synchronous pulleys and two sets of drive belts are provided. The two sets of synchronous pulleys are coaxially mounted on the drive shaft, which drives the two sets of synchronous pulleys to rotate synchronously.

[0012] For example, the dual-station feeding device provided in at least one embodiment of this utility model further includes:

[0013] The gantry frame is provided with a guide rail along its own length, and the sliding frame is provided with a plurality of guide wheels that rotatably abut against the guide rail and are used to roll along the guide rail.

[0014] For example, the dual-station feeding device provided in at least one embodiment of this utility model further includes:

[0015] Two baffles are symmetrically arranged on the frame, and the two baffles are located on both sides of the material distribution conveyor. The baffles are used to block the products on the material distribution conveyor to prevent them from falling.

[0016] For example, the parallel palletizing production line provided in at least one embodiment of this utility model further includes:

[0017] It also includes two parallel subcontracting conveyor lines after the material distribution conveyor. The two sets of subcontracting conveyor lines are used to receive the two rows of products output by the material distribution conveyor. The frame is equipped with a subcontracting mechanism. There are two sets of subcontracting mechanisms, which are located above the two sets of subcontracting conveyor lines respectively. The subcontracting mechanisms are used to clamp and rotate the products on the subcontracting conveyor lines so that the products meet the requirements of horizontal or vertical placement during subsequent palletizing.

[0018] For example, the parallel palletizing production line provided in at least one embodiment of this utility model further includes:

[0019] The subcontracting mechanism includes a support, a rotating frame, and a pair of clamping plates. The support is mounted on the frame and located above the subcontracting conveyor line. The rotating frame is rotatably mounted on the support, and the clamping plates are oscillatingly mounted on the rotating frame. Two sets of clamping plates are symmetrically arranged along the central axis of the rotating frame.

[0020] For example, the parallel palletizing production line provided in at least one embodiment of this utility model further includes:

[0021] The input end of the subcontracting conveyor is provided with a limit plate. There are two sets of limit plates, which are located on both sides of the subcontracting conveyor. The end of the limit plate facing the material distribution conveyor has an inclined guide portion.

[0022] For example, the parallel palletizing production line provided in at least one embodiment of this utility model further includes:

[0023] It also includes a palletizing mechanism connected after the subcontracting conveyor line. The palletizing mechanism includes a palletizing conveyor line, a pusher, and sliding pallets. The palletizing conveyor line is mounted on the frame and is used to receive two rows of products output from the two subcontracting conveyor lines. The pusher is slidably mounted on the frame and located above the palletizing conveyor line. The sliding direction of the pusher is perpendicular to the conveying direction of the subcontracting conveyor line. The sliding pallets are slidably mounted in pairs on the frame. The pusher is used to push the two rows of products stacked on the palletizing conveyor line onto the sliding pallets. The two sliding pallets can slide back to back and open to allow the products to fall onto the tray below.

[0024] For example, the parallel palletizing production line provided in at least one embodiment of this utility model further includes:

[0025] A push plate is slidably mounted on the frame. The push plate is used to abut against the side of the product on the sliding tray to block the product when the sliding tray is opened and prevent the product from moving with the sliding tray.

[0026] The beneficial effects of the embodiments of this utility model are as follows:

[0027] In this invention, during operation, the feeding conveyor transports the products to the middle position of the distributing conveyor. At this time, the distributing plate slides on the gantry. The distributing plate slides to one side, pushing the products located in the middle of the distributing conveyor to that side; the distributing plate slides to the other side, pushing the products located in the middle of the distributing conveyor to that side, thus forming two rows of products on the distributing conveyor. As the distributing conveyor operates, the products are transported to the subsequent stacking position in two rows. During stacking, a pushing operation is performed perpendicular to the product conveying direction. Since the products have already been divided into two rows, the two rows of side-by-side products can be pushed to the designated position at once, thereby completing the stacking of one layer of products.

[0028] This avoids the cumbersome process of traditional single-line production lines requiring two pushes to complete one layer of product stacking, thus improving palletizing efficiency. The reduced number of pushes required for palletizing decreases the frequency of use of various equipment components, effectively slowing down equipment wear and extending its service life.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0038] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0039] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] like Figures 1-6As shown, this invention illustrates a dual-station feeding device according to one embodiment, comprising a frame 1, a feeding conveyor 2, a distributing conveyor 3, a gantry frame 4, and a distributing plate 5. The frame 1 is the basic support structure of the entire dual-station feeding device. The feeding conveyor 2 is mounted on the frame 1 and is in the form of a conveyor belt. The output end of the feeding conveyor 2 is precisely oriented towards the center of the distributing conveyor 3, ensuring that the product can be accurately conveyed to the designated position on the distributing conveyor 3. The distributing conveyor 3 is located after the feeding conveyor 2 and is mounted on the frame 1, also using a conveyor belt. The gantry frame 4 is mounted on the frame 1 and is positioned above the distributing conveyor 3. The distributing plate 5 is slidably mounted relative to the gantry frame 4 and has a flat plate structure. The distributing plate 5 can slide left and right on the gantry frame 4, thereby pushing the product from the center to both sides.

[0044] During operation, the feeding conveyor 2 transports the products to the middle position of the distributing conveyor 3. At this time, the distributing plate 5 slides on the gantry 4. The distributing plate 5 slides to one side, pushing the products located in the middle of the distributing conveyor 3 to that side; the distributing plate 5 slides to the other side, pushing the products located in the middle of the distributing conveyor 3 to that side, so that the products are distributed in two rows on the distributing conveyor 3. As the distributing conveyor 3 operates, the products are transported to the subsequent stacking position in a two-row distribution. During stacking, a pushing operation is performed along the direction perpendicular to the product conveying. Since the products have been divided into two rows, the two rows of side-by-side products can be pushed to the designated position at one time, thereby completing the stacking of one layer of products.

[0045] This avoids the cumbersome process of traditional single-line production lines requiring two pushes to complete one layer of product stacking, thus improving palletizing efficiency. The reduced number of pushes required for palletizing decreases the frequency of use of various equipment components, effectively slowing down equipment wear and extending its service life.

[0046] In some examples, such as Figure 2As shown, synchronous pulleys 6 are rotatably mounted in pairs on the gantry frame 4, and transmission belts 7 are fitted onto the two synchronous pulleys 6. A drive shaft 9 is rotatably mounted on the gantry frame 4. Two sets of synchronous pulleys 6 and transmission belts 7 are provided, with the two sets of synchronous pulleys 6 coaxially mounted on the drive shaft 9, allowing the two sets of transmission belts 7 to move synchronously under the drive of the drive shaft 9. Two sets of sliding frames 8 are provided on the top of the material distribution plate 5, and the two sets of sliding frames 8 are respectively mounted on the two sets of transmission belts 7. When the transmission belts 7 move, the sliding frames 8 move accordingly, thereby driving the material distribution plate 5 to slide. Due to the provision of two sets of transmission belts 7 and sliding frames 8, the material distribution plate 5 can be subjected to uniform tension on both sides during movement, ensuring the stability and straightness of the material distribution plate 5 during sliding. A guide rail 10 is provided along the length of the gantry frame 4, and multiple guide wheels 11 are rotatably mounted on the sliding frames 8, with the guide wheels 11 abutting against the guide rail 10. When the material distribution plate 5 moves, the guide wheel 11 rolls on the guide rail 10, providing guidance for the material distribution plate 5 and ensuring the smooth movement of the material distribution plate 5, avoiding deviation or shaking. Two baffles 12 are symmetrically arranged on the frame 1, located on both sides of the material distribution conveyor 3. They can prevent products from falling off the sides of the material distribution conveyor 3 when the material distribution plate 5 pushes the products.

[0047] When the material distribution plate 5 needs to perform material distribution, the motor mounted on the gantry frame 4 starts, driving the drive shaft 9 to rotate. This causes the two sets of synchronous pulleys 6 to rotate synchronously, driving the drive belt 7 mounted on it to move. The movement of the drive belt 7 drives the sliding frame 8 mounted on it to move, thus realizing the sliding of the material distribution plate 5. The arrangement of the two sets of drive belts 7 and the sliding frame 8 ensures that the force on both sides of the material distribution plate 5 is uniform during the sliding process, avoiding tilting or jamming of the material distribution plate 5 due to uneven force. During the sliding process of the material distribution plate 5, the guide wheel 11 contacts the guide rail 10 and rolls along the guide rail 10, ensuring the accuracy of the moving direction of the material distribution plate 5. At the same time, it reduces the resistance during the movement of the material distribution plate 5, further improving the smoothness of the movement of the material distribution plate 5.

[0048] In some examples, the parallel palletizing production line includes a dual-station feeding device and two subcontracting conveyor lines 13 connected in parallel after the material distribution conveyor 3, the two sets of subcontracting conveyor lines 13 being used to receive the two rows of products output from the material distribution conveyor 3 respectively.

[0049] In order to improve the stability of palletizing, each product stack has two rows of products: one row of three products placed vertically and the other row of two products placed horizontally. In addition, the two rows of products in adjacent product stacks are placed upside down, thereby increasing the overall stability of palletizing.

[0050] Therefore, in the parallel palletizing production line, to meet the product placement direction requirements of this palletizing method, a subcontracting conveyor line 13 and a subcontracting mechanism 14 are added. Two subcontracting conveyor lines 13 are connected in parallel after the material distribution conveyor 3, and are used to receive the two rows of products output from the material distribution conveyor 3 respectively. The two subcontracting conveyor lines 13 are arranged in parallel and connected to the output end of the material distribution conveyor 3. The subcontracting conveyor line 13 adopts the form of a conveyor belt. A limit plate 18 is provided at the input end of the subcontracting conveyor line 13. There are two sets of limit plates 18, located on both sides of the subcontracting conveyor line 13. The end of the limit plate 18 facing the material distribution conveyor 3 has an inclined guide portion 19, which is a sloping surface to guide the products into the subcontracting conveyor line 13.

[0051] Two sets of subcontracting mechanisms 14 are provided, located above the two sets of subcontracting conveyor lines 13 respectively. Each subcontracting mechanism 14 includes a bracket 15, a rotating frame 16, and a pair of clamping plates 17. The bracket 15 is fixedly installed on the frame 1, located directly above the subcontracting conveyor line 13, providing a mounting base for the rotating frame 16 and the clamping plates 17. The rotating frame 16 is rotatably mounted on the bracket 15 and can rotate around its own axis. In this embodiment, the rotation angle is mainly 90 degrees, and the rotating frame 16 can be driven to rotate by a rotary motor mounted on the bracket 15. The clamping plates 17 are oscillatingly mounted on the rotating frame 16. The clamping plates 17 can be driven by hinged to the two ends of the telescopic cylinder on the clamping plates 17 and the rotating frame 16 respectively. Two sets of clamping plates 17 are symmetrically arranged along the central axis of the rotating frame 16. The clamping plates 17 can swing on the rotating frame 16 to achieve the clamping and releasing action of the product.

[0052] The sorting conveyor 3 transports the two rows of sorted products to the two subcontracting conveyor lines 13. If a product's position deviates when entering the subcontracting conveyor line 13, it can follow the inclined guide section 19 between the two sets of limiting plates 18, ensuring the product is neatly arranged on the subcontracting conveyor line 13. When the product is conveyed to below the subcontracting mechanism 14, the two sets of clamping plates 17 swing, approaching and holding the product, while the rotating frame 16 rotates 90 degrees under the drive of a motor mounted on the bracket 15. This rotation operation allows for the horizontal or vertical conversion of the product, meeting the placement requirements during subsequent palletizing.

[0053] By arranging products on the subcontracting conveyor line 13 and adjusting the product orientation using the subcontracting mechanism 14, each product stack is arranged with three products placed vertically in one row and two products placed horizontally in another row, with adjacent layers placed upside down. This increases the stability of the stacking. The products are more tightly supported, reducing the risk of collapse or deformation during storage and handling, and improving the quality of product stacking.

[0054] In some examples, such as Figure 1As shown, the palletizing conveyor line 21 is mounted on the frame 1, located after the two subcontracting conveyor lines 13, and is used to receive the two rows of products output from the subcontracting conveyor lines 13. It adopts the form of a roller conveyor. A pusher frame 22 is slidably mounted on the frame 1 and located above the palletizing conveyor line 21. The sliding direction of the pusher frame 22 is perpendicular to the conveying direction of the subcontracting conveyor line 13, so as to push the products on the palletizing conveyor line 21 onto the sliding pallet 23. The sliding pallets 23 are slidably mounted in pairs on the frame 1 to receive the products pushed by the pusher frame 22. The two sliding pallets 23 can slide back-to-back and open, allowing the products to fall smoothly onto the tray below. A pusher plate 24 is slidably mounted on the frame 1, its function being to abut the side of the product after it is placed on the sliding pallet 23. There are multiple pusher plates 24, which push the products from different directions, making the products more compact. In this solution, the pusher 22, sliding pallet 23 and push plate 24 can all be driven by common drive components in the prior art, such as telescopic cylinders, lead screws and nuts.

[0055] After the subcontracting mechanism 14 adjusts the direction of the two rows of products, they are conveyed from the two subcontracting conveyor lines 13 to the palletizing conveyor line 21, forming a layout of three vertically placed products in one row and two horizontally placed products in the other row on the palletizing conveyor line 21. At this time, the pusher 22 slides, contacts the two rows of products on the palletizing conveyor line 21, and pushes the products onto the sliding pallet 23.

[0056] Multiple pusher plates 24 abut against the sides of the products from different directions, bringing the products together towards the center, making the arrangement of multiple products more compact and thus enhancing the stability of the stacking. As the sliding pallet 23 opens, the pusher plates 24 continuously abut against the products, acting as a barrier to prevent the products from moving with the sliding pallet 23. Without the support of the sliding pallet 23, the products fall onto the pre-placed tray below under gravity, completing the stacking of one layer of products. Afterwards, the sliding pallet 23 and pusher plates 24 return to their original positions, ready for the next layer of products to be stacked, thus achieving continuous stacking.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
