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] To meet the demands of large-scale, high-speed production, food pallets typically need to be transferred to subsequent multi-channel conveyors via automated conveyor systems.

[0004] The commonly used solution in the industry is to set up a dedicated pallet transport line (usually a single-line structure). The main task of this transport line is to move empty pallets or pallets loaded with food to designated pre-positioned locations located above or at the entrance of a multi-channel conveyor. Its typical workflow is as follows: Pallets from upstream are sequentially fed into this single pallet transport line and arranged in order at designated preparatory positions to form a queue. When the number of pallets in the queue reaches a specified number, a special push-out device is activated to push all the pallets in the queue laterally out of the pallet transport line at the same time. The pushed-out pallets leave the pallet transport line and fall or slide into the corresponding channels of the multi-channel conveyor below by gravity or auxiliary guiding devices.

[0005] This structure has the following obvious shortcomings: First, because multiple pallets need to be arranged sequentially on the pallet transport line, there is often a long waiting time, which leads to the multi-channel conveyor being idle and waiting, thus reducing its utilization efficiency.

[0006] Secondly, the conveying capacity of a single pallet transport line has a bottleneck, making it difficult to meet the needs of high-speed and continuous production, and easily becoming a restrictive link in the entire production process. Utility Model Content

[0026] Reference Figures 1 to 5The pallet loading device has a first direction, a second direction, and a vertical direction. The first direction, the second direction, and the vertical direction are orthogonal to each other. 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 vertical direction is parallel to the Z-axis in the figure.

[0027] The pallet loading device includes: a frame 100, a multi-channel conveyor line 200, pallet transport components and a pause conveyor device 400.

[0028] A multi-channel conveyor line 200 is fixedly installed on the frame 100. The multi-channel conveyor line 200 is provided with multiple pallet conveying channels 201, all extending along a first direction and arranged parallel to each other. The pallet conveying channels 201 are used to guide and convey pallets, ensuring that the pallets are conveyed along the first direction. Specifically, in this embodiment, the number of pallet conveying channels 201 is set to sixteen, meaning this multi-channel conveyor line 200 is a sixteen-channel conveyor line. In other embodiments, those skilled in the art can select the number of pallet conveying channels 201 according to actual needs.

[0029] Specifically, in this embodiment, the multi-channel conveyor line 200 includes components such as a multi-channel drive unit, a multi-channel conveyor shaft, a multi-channel conveyor belt, and a multi-channel divider plate 210.

[0030] The multi-channel drive unit is configured as a rotary motor and is fixedly mounted on the frame 100.

[0031] The multi-channel conveyor shaft is rotatably connected to the frame 100. Two multi-channel conveyor shafts are arranged along the first direction. One of the multi-channel conveyor shafts is fixedly connected to the output end of the multi-channel drive unit. Specifically, in this embodiment, the multi-channel conveyor shaft located at the front end of the multi-channel conveyor line 200 is fixed to the output shaft of the multi-channel drive unit.

[0032] The multi-channel conveyor belt passes around two multi-channel conveyor shafts, and the multi-channel conveyor belt is connected to the multi-channel conveyor shafts for transmission.

[0033] The multi-channel guide plate 210 is fixedly connected to the frame 100 and is positioned above the multi-channel conveyor belt. The upper end face of the multi-channel conveyor belt and the side walls of two adjacent multi-channel guide plates 210 form a pallet conveying channel 201. The multi-channel guide plate 210 separates multiple pallets arranged along the second direction on the multi-channel conveyor line 200 to prevent interference between pallets. The spacing between each pallet conveying channel 201 is uniform to accommodate the width of the pallets.

[0034] In this embodiment, the number of pallet transport components is set to two. In other embodiments, the number of pallet transport components may also be set to three, four, or other numbers. Those skilled in the art can select the number of pallet transport components according to actual needs.

[0035] The pallet transport components include: a pallet feeding conveyor 310, a pallet storage conveyor 320, a pallet slide 330, a pallet transfer structure 340, and a pallet side limiting structure 350.

[0036] The pallet feeding conveyor 310 is used to receive upstream pallets and transport them to the pallet storage conveyor 320. The pallet feeding conveyor 310 includes a first feeding section 311 and a second feeding section 312. Both the first feeding section 311 and the second feeding section 312 are fixedly installed on the frame 100.

[0037] Both the first feeding section 311 and the second feeding section 312 are configured as conventional belt conveyor structures. Those skilled in the art can select the specific structure of the first feeding section 311 and the second feeding section 312 according to actual needs.

[0038] In this embodiment, the first feeding segment 311 extends along the first direction, and the second feeding segment 312 extends along the second direction. The first feeding segment 311 and the second feeding segment 312 are connected at right angles so that the pallet feeding conveyor line 310 forms a corner conveying path, thereby enabling the pallet feeding conveyor line 310 to flexibly adapt to the layout of other upstream and downstream equipment.

[0039] In other embodiments, the first feed segment 311 may also be configured to extend at an angle relative to the first direction and the second direction. Those skilled in the art can design the extension direction of the first feed segment 311 according to other upstream and downstream equipment.

[0040] Specifically, in this embodiment, a corner support plate 313 and a transverse feeding mechanism 314 are provided at the corner connecting the first feeding section 311 and the second section.

[0041] The corner support plate 313 is fixedly connected to the frame 100. The corner support plate 313 is used to temporarily support the pallet located at the corner of the pallet feeding conveyor line 310.

[0042] The transverse feeding mechanism 314 is located above the corner support plate 313 and is fixedly installed on the frame 100. Specifically, the transverse feeding mechanism 314 includes: feeding drive motor 510, feeding drive wheel, feeding circulation structure and feeding unit 520 (the feeding drive wheel and feeding circulation structure are not shown in the figure).

[0043] The feeding drive motor 510 is fixedly installed on the frame 100, and the feeding drive unit is set as a rotary motor or a servo motor.

[0044] The feeding drive wheel is rotatably connected to the frame 100, and its rotation axis is parallel to the first direction. Two feeding drive wheels are provided, arranged along the second direction. One of the feeding drive wheels is fixedly connected to the output end of the feeding drive unit.

[0045] The material feeding circulation structure is set as a synchronous belt structure, which bypasses two material feeding drive wheels and is connected to the material feeding drive wheels through a transmission.

[0046] The feeding unit 520 is fixedly installed on the feeding circulation structure. The feeding drive unit drives the feeding unit 520 to move in the second direction through the feeding drive wheel and the feeding circulation structure, so as to push the pallet on the corner support plate 313 to move in the second direction, so that the pallet detaches from the corner support plate 313 and enters the second feeding section 312. After the pallet enters the second feeding section 312, it is driven by the second feeding section 312 to be conveyed in the second direction.

[0047] Specifically, in this embodiment, the number of feeding units 520 is set to multiple, and the multiple feeding units 520 are evenly arranged in the feeding circulation structure. By setting multiple feeding units 520, the transverse feeding mechanism 314 can continuously push multiple trays.

[0048] When a pallet enters from the first feeding section 311 to the second feeding section 312, since the conveying directions of the first feeding section 311 and the second feeding section 312 are different, if the pallet directly enters from the first feeding section 311 to the second feeding section 312, the bottom of the pallet will directly contact the conveying surface of the second feeding section 312, which may cause the pallet to jam or slip. By setting a corner support plate 313 and a transverse material feeding mechanism 314, the bottom of the pallet can be prevented from slipping, which may cause multiple pallets to get stuck in the same position, so as to ensure that the pallet feeding conveyor line 310 can convey the pallets normally and smoothly.

[0049] The pallet storage conveyor line 320 is connected to the second infeed section 312 of the pallet feeding conveyor line 310, and the pallet storage conveyor lines 320 of the two pallet transport components are arranged at intervals along the first direction. The pallet storage conveyor line 320 is configured as a conventional belt conveyor line structure, and the pallet storage conveyor line 320 is used to transport pallets along the second direction.

[0050] The front end of the pallet storage conveyor line 320 (the end away from the second feeding section 312) is provided with a baffle structure 321. In this embodiment, the baffle structure 321 is configured as a baffle-shaped component. The baffle structure 321 is fixedly connected to the frame 100. The baffle structure 321 is used to restrict the pallet located at the front to prevent the pallet at the front from continuing to move forward, so that multiple pallets are closely arranged along the second direction on the pallet storage conveyor line 320 to form a pallet queue.

[0051] The pallet slide 330 is fixedly installed on the frame 100. The pallet slide 330 is located on one side of the pallet storage conveyor line 320 in the first direction. The pallet slide 330 is provided with multiple pallet sliding channels, which correspond one-to-one with the multiple pallet conveying channels 201 of the multi-channel conveyor line 200. Each pallet sliding channel is inclined from top to bottom, and its lowest point is located above the corresponding pallet conveying channel 201. When a pallet enters the pallet sliding channel, the pallet slides down along the pallet sliding channel by its own weight or with the help of other auxiliary structures, and finally detaches from the pallet sliding channel and enters the pallet conveying channel 201.

[0052] The multiple pallet sliding channels of the pallet slide 330 are separated by the pallet separation structure 331. The pallet separation structure 331 has two pallet separation surfaces 332 arranged opposite to each other. The distance between the two pallet separation surfaces 332 gradually increases in the direction away from the pallet storage conveyor line 320, so that the distance between two adjacent pallets gradually increases during the process of sliding down the pallet slide 330, thereby realizing the separation of two adjacent pallets.

[0053] The pallet transfer structure 340 is used to move multiple pallets stored and arranged on the pallet storage conveyor line 320 to the pallet slide 330 along a first direction. Specifically, the pallet transfer structure 340 includes: a pusher drive unit 341 and a pusher unit 342.

[0054] The pusher drive unit 341 includes a pusher drive motor, a pusher drive wheel, and a pusher drive belt.

[0055] The pusher drive motor is fixedly installed on the frame 100.

[0056] The pusher drive wheel is rotatably connected to the frame 100. The number of pusher drive wheels is set to two. The two pusher drive wheels are arranged along the first direction. One of the pusher drive wheels is fixedly connected to the output end of the pusher drive motor. The pusher drive motor drives the corresponding pusher drive wheel to rotate around an axis parallel to the second direction.

[0057] The pusher drive belt passes over two pusher drive wheels, and the pusher drive belt is connected to the pusher drive wheels for transmission.

[0058] In other embodiments, the pusher drive unit 341 may also be configured as a linear cylinder or linear motor or other conventional linear drive components. Those skilled in the art can select the specific structure of the pusher drive unit 341 according to actual needs.

[0059] The pushing unit 342 is slidably connected to the frame 100. The pushing unit 342 and the frame 100 are slidably connected via a guide rail and a guide seat. By providing a guide rail and a guide seat between the pushing drive unit 341 and the frame 100, the pushing unit 342 can be guided so that it moves relative to the frame 100 in a first direction. The pushing unit 342 is fixedly connected to the output end of the pushing drive unit 341. The pushing unit 342 is positioned above the pallet storage conveyor line 320. The pushing unit 342 is equipped with a pushing section, which is a plate-shaped component extending in a second direction. When the pushing section moves in the first direction, it can simultaneously push multiple pallets arranged in the second direction, causing multiple pallets to simultaneously detach from the pallet storage conveyor line 320 and enter the pallet slide 330.

[0060] The pause conveying device 400 is disposed at one end of the pallet storage conveying line 320 near the pallet feeding conveying line 310. The pause conveying device 400 includes: a pause drive unit 410, a pause first clamping unit 420, and a pause second clamping unit 430.

[0061] The pause drive unit 410 is fixedly installed on the frame 100. In this embodiment, the pause drive unit 410 is set as a linear cylinder. In other embodiments, the pause drive unit 410 can also be set as a linear motor or other conventional linear drive device. Those skilled in the art can select the specific structure of the pause drive unit 410 according to actual needs.

[0062] The first clamping unit 420 is configured as a block structure and is fixedly installed at the output end of the pause drive unit 410. The pause drive unit 410 drives the first clamping unit 420 to move along the first direction.

[0063] The second clamping unit 430 and the first clamping unit 420 are arranged along the first direction on both sides of the pallet storage conveyor line 320 and are positioned opposite each other. The second clamping unit 430 is configured as a plate-shaped component and is fixedly connected to the frame 100.

[0064] When the first clamping unit 420 moves closer to the second clamping unit 430, it can clamp the pallet, thereby stopping the pallet from continuing to be transported in the second direction. This prevents the pallet from continuing to be transported in the second direction during the operation of the pallet transfer structure 340, so that subsequent steps can be carried out smoothly and normally.

[0065] The pallet side limiting structure 350 includes: a side limiting drive unit 351 and a side limiting member 352.

[0066] The side limit drive unit 351 is fixedly installed on the frame 100 and is positioned above the pallet storage conveyor line 320. Specifically, in this embodiment, the side limit drive unit 351 is configured as a linear cylinder. In other embodiments, the side limit drive unit 351 can also be configured as a conventional linear drive device such as a linear motor. Those skilled in the art can select the specific structure of the side limit drive unit 351 according to actual needs.

[0067] Specifically, in this embodiment, the number of side limit drive units 351 is set to two, and the two side limit drive units 351 are arranged at intervals along the second direction.

[0068] The side limiting member 352 is a plate-shaped component. The side limiting member 352 is fixed to the output end of the side limiting drive unit 351. The side limiting drive unit 351 drives the side limiting drive member to move closer to or away from the intersection of the pallet slide 330 and the pallet storage conveyor line 320 in the vertical direction. The side limiting member 352 is used to limit the position of the pallet in the first direction to prevent the pallet from accidentally moving from the pallet storage conveyor line 320 to the pallet slide 330 due to vibration or other external forces during equipment operation, thereby ensuring that the pallet loading device can work normally.

[0069] The working process of this pallet loading device is as follows: 1. The upstream equipment sequentially feeds the pallets into the first feeding section 311; 2. The pallet passes through the corner support plate 313 and enters the second feeding section 312 under the action of the transverse feeding mechanism 314; 3. The pallets continue to be conveyed to the storage conveyor line in the second direction, and form a pallet queue that is closely arranged in the second direction under the obstruction of the retaining structure 321; 4. When the pallet transfer structure 340 is in operation, the pushing unit 342 moves along the first direction toward the pallet slide 330, pushing multiple pallets to move simultaneously along the first direction to the pallet slide 330. 5. The pallet slides down the pallet drop channel and finally falls into the corresponding pallet conveying channel 201 of the multi-channel conveyor line 200; 6. The multi-channel conveyor line 200 continues to transport the pallet along the first direction to the downstream processing equipment.

[0070] This invention, by setting up multiple pallet transport components, can effectively reduce the idle waiting time of multi-channel conveyor equipment by transporting pallets to the multi-channel conveyor equipment. This can effectively improve the utilization efficiency of the multi-channel conveyor, and the multiple pallet transport components can meet the production needs of high-speed and continuous production, thereby effectively improving the production efficiency of enterprises.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
