Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a tray feeding device. Background Technology

[0002] In the food processing industry, to achieve efficient automated production processes, it is often necessary to temporarily and neatly load semi-finished or finished food products that have completed specific processes (such as shaping, filling, coating, cooking, etc.) onto pallets. This palletizing operation mainly serves two core purposes: first, to facilitate subsequent material handling, centralized cooling / freezing, or efficient packaging; and second, to provide necessary physical support and protection for the product, maintaining its final shape and preventing deformation or damage.

[0003] In actual production, after initial processing, the aforementioned products typically undergo a series of steps including palletizing, freezing, and sorting. The palletizing step involves manually or mechanically placing the products accurately into pallets, which are then conveyed by a transport system to a freezing facility for cryogenic treatment. After freezing, the products are sorted from the pallets to proceed to packaging or downstream processes.

[0004] However, existing processing lines generally use a single conveyor line structure, which is responsible for transporting pallets containing products to refrigeration equipment for processing.

[0005] This design has obvious limitations: First, the processing capacity of a single-line conveyor is limited and it is difficult to meet the needs of high-capacity production; second, since refrigeration equipment is usually a high-power device with high operating costs, single-line transmission results in the refrigeration equipment's processing capacity not being fully utilized, leading to low resource utilization.

[0025] Reference Figures 1 to 5 The pallet handling device has a first direction, a second direction, and a third direction, which are orthogonally arranged. The first direction is parallel to the X-axis in the figure, the second direction is parallel to the Y-axis in the figure, and the third direction is parallel to the Z-axis in the figure. The definition of the above directions can effectively guide the layout and standardized expression of the movement direction of each component.

[0026] The pallet sorting device comprises the following core components: frame 100, pallet sorting infeed conveyor line 200, pallet sorting outfeed conveyor line 300, and pallet sorting ejection mechanism 400. These components work together to complete a series of actions, including pallet sorting, conveying, limiting, and ejection, thereby improving the automation level and operational efficiency of the entire line.

[0027] The pallet feeding conveyor line 200 and the pallet feeding discharging conveyor line 300 are both fixedly installed on the frame 100.

[0028] In this embodiment, the number of pallet feeding conveyor lines 200 is set to two. In practical applications, the number of pallet feeding conveyor lines 200 can be set to three, four, or more channels, depending on parameters such as pallet size, production line cycle time, and feeding frequency. Those skilled in the art can flexibly adjust the specific number according to actual application scenarios to meet different needs.

[0029] The pallet feeding conveyor line 200 is further divided into two sections, including a first feeding section 210 and a second feeding section 220. The second feeding section 220 is connected to the first feeding section 210. Specifically, in this embodiment, the first feeding section 210 is configured as a turning conveyor, and the second feeding section 220 is configured as a straight conveyor. In other embodiments, both the first feeding section 210 and the second feeding section 220 can be configured as straight conveyors, and arranged at right angles. Those skilled in the art can select the specific structure of the first feeding section 210 and the second feeding section 220 according to actual needs.

[0030] To improve the stability of pallets passing through turns and prevent problems such as overturning or jamming due to speed changes or trajectory deviations during turning, in this embodiment, a pallet limiting structure 211 is provided at the turning point of the first material feeding section 210. The pallet limiting structure 211 is fixedly connected to the frame 100 and is a guide rail structure with a curved section. The pallet limiting structure 211 is located above the turning point of the first material feeding section 210. Through the guiding effect of the pallet limiting structure 211, it can be ensured that the bottom of the pallet remains in contact with the conveying surface during turning, reducing pallet posture changes, improving operational stability, thereby ensuring that the pallet can smoothly complete the turning conveying action and improving the reliability of the entire line operation.

[0031] The pallet feeding conveyor 200 is equipped with an ejection waiting area, which serves as a temporary buffer and arrangement area for pallets. The ejection waiting area is located in the second feeding section 220. Pallets are arranged in the ejection waiting area and await ejection. The ejection waiting areas of the two pallet feeding conveyors 200 are arranged along a first direction.

[0032] Specifically, in this embodiment, the pallet feeding and conveying line 200 also includes a pallet feeding end limiting component 230. The pallet feeding end limiting component 230 is used to achieve precise control of the pallet entering the ejection waiting area, so as to avoid the pallet entering the waiting area due to inertia or conveying error and interfering with subsequent operations.

[0033] The material handling end limiting assembly 230 includes a material handling end limiting unit 231 and a material handling end limiting drive unit 232.

[0034] The material handling end limit drive unit 232 is fixedly installed on the frame 100, and is located at the end of the second material handling feed section 220 away from the first material handling feed section 210. In this embodiment, the material handling end limit drive unit 232 is configured as a linear cylinder. In other embodiments, the material handling end limit drive unit 232 can also be configured as a conventional linear drive structure such as a linear motor, a lead screw module, or a belt module. Those skilled in the art can select the specific structure of the material handling end limit drive unit 232 according to actual needs.

[0035] The material handling end limiting unit 231 is fixedly installed at the output end of the material handling end limiting drive unit 232. The material handling end limiting unit 231 is configured as a plate-shaped component. The material handling end limiting drive unit 232 drives the material handling end limiting unit 231 to move along the second direction, so that the material handling end limiting unit 231 moves closer to or further away from the ejection waiting area.

[0036] Specifically, the operation process of the material handling end limiting component 230 is as follows: when it is necessary to limit the pallet on the second material handling feed section 220, the material handling end limiting drive unit 232 drives the material handling end limiting unit 231 to approach the ejection waiting area. After the pallets in the ejection waiting area are arranged (after the number of pallets reaches the set value), the material handling end limiting drive unit 232 drives the material handling end limiting unit 231 to move away from the ejection waiting area to avoid obstructing the subsequent movement of other mechanisms.

[0037] In other embodiments, the material handling end limiting drive unit 232 may be omitted, and the material handling end limiting unit 231 may be fixed to the frame 100. Those skilled in the art can select the specific structure of the material handling end limiting component 230 according to actual needs.

[0038] Specifically, in this embodiment, the pallet feeding conveyor line 200 also includes a feeding control component 240. The feeding control component 240 is located at the beginning of the second feeding section 220 (i.e., the end of the second feeding section 220 that is close to the first feeding section 210).

[0039] The material handling control assembly 240 includes: a material handling control drive unit, a first material handling control component, and a second material handling control component.

[0040] The material handling control drive unit is fixedly mounted on the frame 100. In this embodiment, the material handling control drive unit is a linear cylinder. In other embodiments, the material handling control drive unit can also be a conventional linear drive device such as a linear motor, or a rotary drive device. Those skilled in the art can select the specific structure of the material handling control drive unit according to actual needs.

[0041] The first material handling control component is fixedly installed at the output end of the material handling control drive unit, and the first material handling control component is configured as a block-shaped component.

[0042] The second material handling control component is fixedly installed on the frame 100, and the second material handling control component is arranged opposite to the first material handling control component.

[0043] Once the designated number of pallets in the ejection waiting area have been reached, other mechanisms need to perform actions within the ejection waiting area. At this point, it is necessary to pause the entry of pallets into the ejection waiting area. The material handling control drive unit drives the first material handling controller to approach the second material handling controller. The first and second material handling controllers clamp the pallet closest to the ejection waiting area, stopping the pallet from continuing to be conveyed in the second direction. This prevents the pallet from accidentally entering the ejection waiting area and affecting the operation of other mechanisms, thus ensuring the normal operation of other mechanisms.

[0044] The pallet sorting and unloading conveyor line 300 is configured as a conventional belt conveyor, and its conveying direction is parallel to the first direction. The pallet sorting and unloading conveyor line 300 and the ejection waiting area are arranged along the first direction. The pallet sorting and unloading conveyor line 300 is used to receive pallets from each pallet sorting infeed conveyor line 200 and to transport multiple pallets into subsequent processes in a unified manner.

[0045] Specifically, in this embodiment, the second feeding sections 220 of the two pallet feeding conveyors 200 are arranged in opposite directions, and the first feeding sections 210 of the two pallet feeding conveyors 200 are respectively arranged on both sides of the pallet feeding discharge conveyor 300 in the second direction. Arranging the first feeding sections 210 on both sides of the pallet feeding discharge conveyor 300 can avoid the two first feeding sections 210 being arranged too closely, thereby reducing the difficulty of maintenance and assembly.

[0046] The pallet feeding and ejection mechanism 400 includes: a first feeding and ejection drive unit 410, a second feeding and ejection drive unit 420, and a feeding and ejection component 430.

[0047] The first material feeding and ejection drive unit 410 is fixedly installed on the frame 100, and the driving direction of the first material feeding and ejection drive unit 410 is parallel to the first direction. Specifically, in this embodiment, the first material feeding and ejection drive unit 410 is configured as a belt-driven linear module. In other embodiments, the first material feeding and ejection drive unit 410 can also be configured as a linear module of linear cylinder, linear motor, or ball screw. Those skilled in the art can select the specific structure of the first material feeding and ejection drive unit 410 according to actual needs.

[0048] The second material feeding and ejection drive unit 420 is fixedly installed at the output end of the first material feeding and ejection drive unit 410, and the driving direction of the second material feeding and ejection drive unit 420 is parallel to the third direction. Specifically, in this embodiment, the second material feeding and ejection drive unit 420 is configured as a linear cylinder. In other embodiments, the second material feeding and ejection drive unit 420 can also be configured as a linear motor, a belt-driven linear module, or a ball screw-driven linear module. Those skilled in the art can select the specific structure of the second material feeding and ejection drive unit 420 according to actual needs.

[0049] The material feeding ejector 430 is fixedly installed at the output end of the second material feeding ejection drive unit 420, and is positioned above the pallet material feeding and discharge conveyor line 300. The material feeding ejector 430 has multiple pushing parts 431. Specifically, in this embodiment, the number of pushing parts 431 is set to two, with the two pushing parts 431 spaced apart along a first direction. The two pushing parts 431 are respectively used to push the pallets on the two pallet material feeding and discharge conveyor lines 200, maintaining a certain distance between the pallets on the two pallet material feeding and discharge conveyor lines 200 as they move along the first direction. The pushing part 431 is a plate-shaped component, extending along a second direction. In other embodiments, one pushing part 431 can also push multiple pallets on the pallet material feeding and discharge conveyor lines 200 to move along the first direction. Those skilled in the art can select the number of pushing parts 431 according to actual needs.

[0050] When the pallet feeding and ejection mechanism 400 is working, the first feeding and ejection drive unit 410 drives the second feeding and ejection drive unit 420 and the feeding and ejection component 430 to move along the first direction. The multiple pushing parts 431 of the feeding and ejection component 430 push the pallets on the multiple pallet feeding and ejection conveyor lines 200 respectively, so that the two rows of pallets move from the two ejection waiting areas to the starting end of the pallet feeding and ejection conveyor line 300.

[0051] After the pallet feeding and ejection mechanism 400 pushes the pallet to the pallet feeding and ejection conveyor line 300, the second feeding and ejection drive unit 420 drives the feeding and ejection component 430 away from the pallet feeding and ejection conveyor line 200 along a third direction. Then, the first feeding and ejection drive unit 410 drives the second feeding and ejection drive unit 420 and the feeding and ejection component 430 away from the pallet feeding and ejection conveyor line 300 along a first direction, so that the second feeding and ejection drive unit 420 and the feeding and ejection component 430 are reset to the position before ejecting the pallet. Then, the second feeding and ejection drive unit 420 drives the feeding and ejection component 430 closer to the pallet feeding and ejection conveyor line 200 along a third direction, so that the feeding and ejection component 430 is reset and waits for the next time to push the pallet to the pallet feeding and ejection conveyor line 300.

[0052] In other embodiments, the material feeding ejector 430 can also be directly mounted on the output end of the first material feeding ejection drive unit 410. However, during the reset process of the first material feeding ejection drive unit 410 driving the material feeding ejector 430, there cannot be any pallets in the ejection waiting area of ​​the pallet material feeding conveyor line 200, which will reduce the efficiency of the pallet material feeding device. Those skilled in the art can select the specific structure of the pallet material feeding ejection mechanism 400 according to actual needs.

[0053] The beneficial effects of this embodiment are summarized as follows: By operating multiple pallet feeding and conveying lines 200 in parallel within this device, the overall processing capacity of the system is significantly improved, making it particularly suitable for high-capacity demand scenarios. After the pallet feeding process, the materials can be uniformly conveyed to subsequent processes. Especially for equipment such as refrigeration equipment that has strict rhythm requirements and high energy consumption, this device can significantly improve its utilization efficiency, thereby optimizing resource allocation, reducing energy waste, and improving the overall efficiency of the production line.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
