Description

Technical Field

[0001] This application relates to the technical field of food processing machinery, and in particular to a multi-row tray feeding machine. Background Technology

[0002] In the food production process, the neat arrangement of products is particularly important for subsequent processing, especially when placing products on baking trays. Ensuring that the products are positioned and spaced evenly on the baking trays can improve the baking effect.

[0003] Traditional dough tray arranging machines typically place each dough ball individually on the lower tray during the arranging process. This method maximizes the integrity and aesthetic appeal of the dough balls during tray arrangement.

[0004] Regarding the aforementioned technologies, the method of arranging trays one by one results in a slow tray arrangement speed. The inventor believes that this method has drawbacks such as low work efficiency, large production line footprint, and high production costs. Summary of the Invention

[0005] In order to improve tray arrangement efficiency, reduce production line size, and lower production costs, this application provides a multi-row tray arrangement machine.

[0006] The multi-row tray arrangement machine provided in this application adopts the following technical solution:

[0007] A multi-row tray feeding machine includes a frame, on which a tray feeding device for continuously feeding trays is mounted. The length direction of the tray feeding device is parallel to the length direction of the tray. A support frame is mounted below the tray feeding device, extending from the tray feeding device along one side of the tray width direction. A tray delivery device is mounted on the support frame to drive the tray to slide along the length direction of the support frame. A mounting frame is mounted on one side of the support frame along the width direction. A conveyor belt is mounted on the mounting frame, with the forward direction of the conveyor belt parallel to the width direction of the support frame. A sliding drive device is mounted on the frame to drive the mounting frame to slide along the forward direction of the conveyor belt.

[0008] By adopting the above technical solution, workers place a large number of pallets into the pallet feeding device, while simultaneously placing rows of products to be processed at the end of the conveyor belt away from the support frame. The pallet feeding device continuously places pallets onto the support frame along its length. The pallet delivery device drives the pallets to move along the length of the support frame. When any pallet moves to the underside of the conveyor belt, the sliding drive device drives the mounting frame to move closer to the pallet. At the same time, the conveyor belt moves the rows of products to the end of the conveyor belt. When the end of the conveyor belt moves above the pallet, the conveyor belt continues to move the rows of products forward, while the mounting frame quickly moves away from the pallet. The rows of products fall onto the pallet due to gravity and inertia, thus completing the pallet arrangement operation.

[0009] Preferably, the support frame includes support rods for supporting the tray. The support rods are horizontally arranged, with one end of the support rod along its length located below the tray feeding device. Two support rods are symmetrically arranged on both sides of the support frame in the width direction. The tray feeding device includes a tray feeding motor mounted on the frame. Sprockets are also provided on the lower sides of both ends of the support rods. The sprockets are vertically arranged, with their axes parallel to the width direction of the support frame. There is one sprocket at each end of the support rod in the length direction. A set of two sprockets is provided on each of the two support rods. The two symmetrical sprockets on both sides are coaxially fixed. A synchronous chain is wound around the two sprockets on the lower side of the same support rod. The output shaft of the tray feeding motor is coaxially fixed to any one of the sprockets. Push plates are provided on the two chains. The push plates are vertically arranged, with their length direction parallel to the length direction of the tray. The two ends of the push plates in the length direction are respectively fixed to the two chains. Multiple push plates are spaced apart along the length direction of the support rod. The tray is placed between two push plates.

[0010] By adopting the above technical solution, the support frame carries the pallet through symmetrical support rods. The pallet feeding motor drives the sprocket to rotate, and the sprocket drives the push plate to slide along the support rod direction through a synchronous chain. The push plate is fixed on the synchronous chains on both sides, which facilitates adjustment according to the size of the pallet. Any pallet is pushed by the corresponding push plate to move along the length of the support rod, completing the transfer from the pallet feeding device to the pallet arrangement station.

[0011] Preferably, the support frame is provided with a baffle on one side along its width direction, the baffle is vertically arranged, and the support frame is provided with a clamping device on the side away from the baffle along its width direction to ensure that the pallet is relatively stationary in the width direction of the support frame.

[0012] By adopting the above technical solutions, the clamping device and baffle help ensure the stability of the pallet in the horizontal direction of the support frame, which facilitates the subsequent positioning of the pallet.

[0013] Preferably, the clamping device includes a base plate, which is vertically arranged and parallel to the width direction of the support rods in the length direction. The base plate is fixed relative to the frame. The base plate and the baffle are located on opposite sides of the two support rods. A clamping plate is provided on the base plate, which is vertically arranged. The end of the clamping plate near the feeding device in the length direction is hinged to the end of the base plate in the length direction. A spring is provided between the clamping plate and the base plate, and the two ends of the spring abut against the sides of the base plate and the clamping plate that are close to each other.

[0014] By adopting the above technical solution, the clamping plate and the base plate are hinged at one end, and the spring makes the clamping plate and the base plate form a certain angle. The clamping plate presses the pallet on the support frame against the baffle, thereby ensuring that the pallet moves stably in the horizontal direction of the support frame.

[0015] Preferably, the frame further includes a positioning frame, and the mounting frame slides and engages with the positioning frame on both sides along the length of the support frame and along the width of the support frame. A mounting plate is fixed on one side of the mounting frame along the length of the support frame. The sliding drive device includes a synchronous belt and two pulleys mounted on the positioning frame. Either pulley is horizontally positioned, and the axis of either pulley is parallel to the length of the support frame. The synchronous belt is wound around the two pulleys. The mounting plate is fixed on the upper or lower side of the synchronous belt. The housing of the sliding drive motor is fixed on the positioning frame, and the output shaft of the sliding drive motor is coaxially fixed with either pulley.

[0016] By adopting the above technical solution, the positioning frame and the mounting frame slide together, allowing the mounting frame to slide along the width of the support frame. The output shaft of the sliding drive motor rotates, driving the pulley to rotate. The synchronous belt, following the pulley, moves the clamping plate, moving the pallet to the predetermined position and completing the product tray arrangement. The mounting frame slides into the positioning frame on both sides, and the conveyor belt has a certain width, allowing workers to place rows of products along its width.

[0017] Preferably, a support plate is fixed on the mounting frame, the support plate is horizontally arranged, and a support roller is arranged on the side of the support plate away from the support frame along the width direction of the support frame. The axis of the support roller is parallel to the length direction of the support frame, and the support roller is rotatably connected to the support plate around its own axis. A rotating plate is arranged on the side of the support plate away from the support roller. The end of the rotating plate near the support plate rotates with the support plate around an axis parallel to the axis of the support roller. A fixing assembly for fixing the rotating plate is also provided on the support plate. A rotating roller is arranged on the end of the rotating plate away from the support plate. The axis of the rotating roller is parallel to the axis of the support roller, and the rotating roller is rotatably connected to the rotating plate around its own axis. A conveyor motor is also provided on the mounting frame, and a conveyor roller is fixed on the output shaft of the conveyor motor. The conveyor belt is sequentially wound around the rotating roller, the conveyor roller, and the support roller.

[0018] By adopting the above technical solution, the support plate provides support for the conveyor belt, the drive motor drives the conveyor roller to rotate, and the rotation of the conveyor roller drives the conveyor belt forward. The support roller and the rotating roller rotate with the conveyor belt, thereby ensuring the smooth forward movement of the conveyor belt. The operator can adjust the angle between the rotating plate and the support plate, thereby changing part of the conveyor belt angle. The rotating plate tilted at a certain angle helps to ensure that when the mounting frame moves the conveyor belt away from the support frame, the products that are moved off the upper side of the conveyor belt are thrown out and fall onto the pallet due to gravity and inertia.

[0019] Preferably, the mounting frame is further provided with multiple tension rollers, the axis of any tension roller is parallel to the axis of the support roller, and any tension roller is rotatably connected to the mounting frame around its own axis. The conveyor belt body is also sequentially wound around the multiple tension rollers to keep the upper side of the conveyor belt body flat. A scraper is provided on the outer side of the tension roller on the side away from the support frame, and the scraper abuts against the surface of the conveyor belt body.

[0020] By adopting the above technical solutions, the tension roller helps maintain the flatness of the upper side of the conveyor belt, ensuring that the conveyor belt remains flatly wound around the support roller and rotating roller after the operator adjusts the rotating plate, thus guaranteeing the conveying effect. The scraper removes residual product residue or other attachments from the conveyor belt, helping to ensure the smooth forward movement of the conveyor belt.

[0021] Preferably, the rotating plate is further provided with a fixing frame, on which a brush is fixed, and the brush is mounted on the outside of the rotating roller away from the support plate.

[0022] By adopting the above technical solution, the brush can remove the floating scum from the product surface, which helps to improve the quality of the finished product and keep the material clean and beautiful.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the automated design of the tray feeding device, tray delivery device, and sliding drive device, continuous traying of multiple rows of products is achieved, significantly improving traying speed and production efficiency. By reducing manual intervention, the automated equipment can stably and quickly transport trays and products to predetermined positions, thereby reducing the error rate of manual operation and improving the overall operating efficiency of the production line.

[0025] 2. The combined design of the clamping device and baffle effectively ensures the stability of the pallet during the palletizing process, preventing pallet displacement. The spring system of the base plate and clamping plate provides additional clamping force, ensuring that the pallet remains stable at all times and avoiding uneven product arrangement due to pallet shaking or displacement, thereby improving palletizing accuracy and product quality consistency;

[0026] 3. It has strong adaptability and can adjust the spacing of the push plates according to the pallet size to meet the needs of pallets of different widths. At the same time, the tension roller and scraper design of the conveyor belt ensures that the conveyor belt always remains flat, reduces the impact of product residue on the conveyor belt operation, and cleans the floating scum on the surface of the material with a brush.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] This application discloses a multi-row tray arrangement machine.

[0035] See also Figure 1 The multi-row tray feeding machine includes a frame 1, which includes an operating platform 11. A tray feeding device 2 is mounted on the operating platform 11, consisting of two opposing lifting machines 21. One side of the tray can be inserted between two adjacent partitions of the corresponding lifting machine 21 along its length. A support frame 12 is positioned between the two lifting machines 21 and is fixed to the operating platform 11. The support frame 12 extends along the width of the tray away from the tray feeding device 2, and its length is parallel to the width of the tray. A tray delivery device 3 is also mounted on the support frame 12. A mounting frame 14 is located in the middle of the support frame 12, slidingly engaging with the frame 1 along its width. A conveyor belt 6 is mounted on the mounting frame 14, with its forward direction parallel to the width of the support frame 12. A sliding drive device for driving the mounting frame 14 to slide is also provided on the frame 1.

[0036] In practice, workers can pre-place multiple pallets between two elevators 21. The elevators 21 sequentially lower the pallets onto the support frame 12. The pallet feeding device 3 moves the pallets along the length of the support frame 12. Simultaneously, workers place rows of products to be processed onto the front end of the conveyor belt 6. The conveyor belt 6 moves forward, carrying the rows of products forward. At the same time, the sliding drive device moves the mounting frame 14 along the forward direction of the conveyor belt 6 towards the side closest to the pallet, until the end of the conveyor belt 6 is above the corresponding pallet. The conveyor belt 6 continues to move the products forward, while the sliding drive device moves the mounting frame 14 rapidly away from the support frame 12. Due to gravity and inertia, the products continue to move towards the side closest to the pallet, falling from the conveyor belt 6 into the pallet, thus completing the pallet arrangement.

[0037] See also Figure 1 , Figure 2 The support frame 12 includes a support rod 121, which is horizontally positioned and parallel to the length of the support frame 12. The support rod 121 is mounted on and fixedly connected to the operating platform 11, with one end of the support rod 121 located between two lifting machines 21. One support rod 121 is located on each side of the tray along its length. The tray feeding device 3 includes a sprocket 31, which is vertically positioned and parallel to the width of the support frame 12. The sprocket 31 is rotatably connected to the frame body 1, and one sprocket 31 is located on the lower side of each end of the support rod 121 along its length. A synchronous chain is wound around the two sprockets 31 on the lower side of each support rod 121. Two sets of sprockets 31 symmetrically positioned on both sides of the support frame 12 along its width are coaxially fixed. A tray feeding motor is also mounted on the frame body 1, with its housing fixed to the frame body 1. The output shaft of the tray feeding motor is coaxially fixed to one of the sprockets 31. A push plate 32 is disposed between two chains. The push plate 32 is vertically positioned, and its length direction is parallel to the width direction of the support frame 12. The lower sides of both ends of the push plate 32 along its length direction are detachably fixed to the two chains respectively. Multiple push plates 32 are evenly spaced along the length direction of any chain. Any tray can be placed between two adjacent push plates 32.

[0038] An extension rod 122 is also provided on the side of the support frame 12 away from the feeding device 2. The length direction of the extension rod 122 is parallel to the length direction of the support rod 121. There is one extension rod 122 on each of the two support rods 121. The end of the extension rod 122 near the support frame 12 is fixed to the end of the corresponding support rod 121 away from the feeding device 2. The two extension rods 122 are arranged symmetrically.

[0039] After the elevator 21 places the pallet on the support rod 121, the pallet feeding motor drives the corresponding sprocket 31 to rotate, thereby driving the chains on both sides forward. The chains on both sides drive the push plates 32 forward, and the push plates 32 push the corresponding pallet to move along the length of the support frame 12. When the corresponding pallet moves to the underside of the conveyor belt 6, the pallet feeding motor stops rotating, making the pallet relatively stationary on the operating table 11. The mounting frame 14 drives the conveyor belt 6 to place multiple rows of products to be processed into the pallet. After the pallet is placed, the pallet feeding motor rotates, thereby driving the push plates 32 to continue moving forward. Multiple push plates 32 drive the pallet with the completed pallet to the extension rod 122, and at the same time, drive the next empty pallet to the underside of the conveyor belt 6. The operator can remove the multiple pallets filled with products placed on the two extension rods 122 at intervals for convenient operation.

[0040] A baffle 41 is provided on the side of the support frame 12 closest to the conveyor belt 6 in the width direction. The baffle 41 is vertically arranged, and its length direction is parallel to the length direction of the support frame 12. A clamping device 4 is provided on the other side of the support frame 12 in the width direction. The clamping device 4 includes a base plate 42, which is vertically arranged and its length direction is parallel to the length direction of the support frame 12. A clamping plate 43 is provided on the side of the base plate 42 closest to the support frame 12. The clamping plate 43 is vertically arranged, and its end closest to the feeding device 2 is hinged to the corresponding end of the base plate 42. A spring 44 is provided between the clamping plate 43 and the base plate 42. The spring 44 is located at the end of the base plate 42 away from the feeding device 2 in the length direction. The two ends of the spring 44 in the axial direction respectively abut against the sides of the base plate 42 and the clamping plate 43 that are close to each other. Multiple clamping devices 4 are continuously arranged on the operating table 11 along the length of the support frame 12. The specific number depends on the length of the base plate 42 and the length of the support rod 121, ensuring that the pallet remains relatively stationary in the width direction of the support frame 12 during movement. In this embodiment, two devices are configured. The conveyor belt 6 is located above the spring 44 inside the clamping device 4 near the pallet supply device 2.

[0041] As the pallet slides on the support frame 12, its length direction is parallel to the width direction of the support frame 12. One side of the pallet abuts against the baffle 41, and the other side abuts against the clamping plate 43 of the corresponding clamping device 4. Since the length of the pallet is greater than the minimum distance between the baffle 41 and the corresponding clamping plate 43, the pallet gradually presses against the clamping plate 43, thereby compressing the spring 44. This helps to ensure that the pallet remains relatively stationary with respect to the support frame 12 along its own length, thus ensuring the stability of the pallet moving when the pallet feeding device 3 moves the pallet, while the conveyor belt 6 precisely positions the pallet.

[0042] See also Figure 1 , Figures 3-5The operating table 11 is also equipped with a positioning frame 13. The mounting frame 14, along the length of the support frame 12, slides along the width of the support frame 12 on both sides of the positioning frame 13 via slider rails. A sliding drive device is mounted on the positioning frame 13 and includes two pulleys, a synchronous belt, and a sliding drive motor 5. The axes of the two pulleys are parallel to the length of the support frame, and the two pulleys are spaced apart on the positioning frame 13 along the width of the support frame 12. Each pulley is rotatably connected to the positioning frame 13 around its own axis. The synchronous belt is wound around the two pulleys. The housing of the sliding drive motor 5 is fixed to the positioning frame 13, and the output shaft of the sliding drive motor 5 is coaxially fixed to either pulley. A mounting plate is provided on the side of the mounting frame 14 along the length of the support frame 12 near the sliding drive device, and the mounting plate is fixed to the upper or lower side of the synchronous belt. The sliding drive motor 5 rotates, causing the pulley to rotate. The pulley drives the synchronous belt to move forward or backward, and the mounting plate moves forward or backward with the synchronous belt, thereby causing the mounting frame 14 to slide along the width direction of the support frame 12.

[0043] A support plate 61 is fixed on the mounting frame 14. The support plate 61 is horizontally positioned, and its length is parallel to the width of the support frame 12. A support roller 62 is mounted on the side of the support plate 61 away from the support frame 12, with its axis parallel to the length of the support frame 12. The support roller 62 is rotatably connected to the support plate 61 around its own axis. A rotating frame 63 is mounted on the side of the support plate 61 away from the support roller 62, and a rotating plate 64 is mounted on the rotating frame 63. The rotating frame 63 and the support plate 61 rotate around an axis parallel to the axis of the support roller 62. The rotating frame 63 and the support plate 61 are detachably fixed with bolts. The length of the rotating plate 64 is parallel to the width of the support plate 61, and the rotating plate 64 is rotatably connected to the rotating frame 63 around its own length. The rotating plate 64 and the rotating frame 63 are detachably fixed with bolts.

[0044] A rotating roller 65 is provided on the side of the rotating plate 64 away from the support plate 61 along its own width direction. The axis of the rotating roller 65 is parallel to the axis of the support roller 62, and the rotating roller 65 is rotatably connected around its own axis. A photoelectric sensor 651 is also provided on the side of the rotating plate 64 near the rotating roller 65. The photoelectric sensor 651 is used to detect whether a product passes through the end of the conveyor belt 6.

[0045] A conveyor roller 66 is also provided on the lower side of the support plate 61, with its axis parallel to that of the support roller 62. A conveyor motor is also provided on the mounting frame 14, with its housing fixed to the frame and its output shaft coaxially fixed to the conveyor roller 66. The conveyor roller 66 is located at the middle of the length of the support plate 61, and multiple tension rollers 67 are provided on both sides of the conveyor roller 66 along the length of the support plate 61. The axis of any tension roller 67 is parallel to that of the support roller 62, and each tension roller 67 is rotatably connected to the mounting frame 14 around its own axis. The conveyor belt 6 is sequentially wound around the support roller 62, the rotating roller 65, the tension roller 67, and the conveyor roller 66. Multiple rubber rings are also fitted on the conveyor roller 66 to increase the friction between the conveyor belt 6 and the conveyor roller 66.

[0046] The rotation of the conveyor motor drives the conveyor roller 66 to rotate, thereby causing the upper belt body of the conveyor belt 6 to move along the width direction of the support frame 12. The tension roller 67 helps to ensure that the upper belt body remains horizontal.

[0047] A scraper 68 is provided on the outer side of a tension roller 67 closest to the support roller 62. The scraper 68 is fixed relative to the mounting frame 14, and the lower side of the conveyor belt 6 passes between the scraper 68 and the tension roller 67. In actual operation, the scraper 68 can remove product residue from the surface of the belt, reducing the impact on the belt's forward movement and minimizing the impact of residue on subsequent products.

[0048] A fixed frame 141 is also fixed on the rotating frame 63, and a brush 142 is fixed on the fixed frame 141. The brush 142 is located on the outer side of the rotating roller 65 away from the support plate 61. When the product to be processed moves to the end of the conveyor belt 6, the sliding drive device drives the entire conveyor belt 6 to move rapidly to the side away from the support frame 12. At the same time, the conveyor belt 6 continues to move the row of products to the side closer to the support frame 12. The row of products falls onto the pallet due to inertia and gravity. During this process, the brush 142 brushes over the top of the product, thereby brushing away the floating scum on the surface of the product.

[0049] The implementation principle of a multi-row palletizing machine according to this application embodiment is as follows: Before actual operation, the operator can insert multiple pallets between two elevators 21. The operator adjusts the angle between the rotating plate 64 and the support plate 61 according to the size of the product to be processed, and fixes the rotating plate 64 and the support plate 61 relative to each other with bolts. During actual operation, the elevators 21 sequentially lower the pallets onto the support frame 12. The pallet feeding motor drives two sets of chains forward, thereby driving the push plate 32 to move along the length of the support frame 12 towards the side opposite to the elevators 21. The push plate 32 sequentially pushes the pallets forward. The clamping plate 43 and the baffle 41 ensure that the pallets remain relatively stationary relative to the support frame 12 in the width direction. When the pallet moves below the conveyor belt 6, the pallet feeding motor stops rotating. Meanwhile, workers place rows of products to be processed in sequence at the front end of conveyor belt 6. The conveyor motor rotates, driving the conveyor roller 66 to rotate. The conveyor roller 66 drives the conveyor belt 6 forward. When the rows of products on conveyor belt 6 move to the end of conveyor belt 6 and are detected by photoelectric sensor 651, the sliding drive motor 5 rotates, driving the synchronous belt forward. Through the mounting plate, the mounting frame 14 is driven, thereby driving the entire conveyor belt 6 to move rapidly to the side away from the support frame 12. At the same time, the conveyor belt 6 continues to move forward. The rows of products at the end of conveyor belt 6 fall onto the corresponding row on the pallet due to inertia and gravity.

[0050] The sliding drive motor 5 rotates in the opposite direction, thereby moving the end of the conveyor belt 6 to the next row on the pallet, repeating the pallet arrangement operation. When the pallet is full, the sliding drive motor 5 rotates, moving the conveyor belt 6 to the position corresponding to the first row of pallets. At the same time, the pallet feeding motor rotates, moving the pallet further away from the elevator 21. After multiple pallets have moved onto the extension rod 122, the worker can remove the pallet filled with products.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
